技术领域technical field
本发明涉及电火花加工技术领域，具体涉及一种电火花加工系统。The invention relates to the technical field of electrical discharge machining, in particular to an electrical discharge machining system.
背景技术Background technique
电火花加工机床在机械制造领域(特别是模具制造领域)有着非常重要的地位，常用于加工各种复杂的型腔，特别是在难加工材料的工件上加工型腔。EDM machine tools play a very important role in the field of mechanical manufacturing (especially in the field of mold manufacturing). They are often used to process various complex cavities, especially for machining cavities on workpieces of difficult-to-machine materials.
然而，电火花加工机床在加工过程中容易出现短路、拉弧等异常放电状态，在深型腔加工中尤其难免，一旦出现，机床便会暂停加工并报警，如果机床操作者不及时干预的话，则会严重影响生产进度。另外，由于电火花加工对材料的去除是一个微观领域的过程，材料去除率相对较低，这也决定了电火花加工机床的加工效率较低，在型腔加工时动辄需要耗费数小时甚至十几个小时。因此，在这漫长的加工时间中，机床操作者往往不敢离开车间(甚至不能远离机床)，但在绝大部分时间里(有时在整个加工过程中)机床放电状态正常，又不需要对机床进行干预，这便造成了对人工的严重浪费。However, EDM machine tools are prone to abnormal discharge states such as short circuits and arcs during processing, especially in deep cavity processing. Once such discharges occur, the machine tool will suspend processing and give an alarm. If the machine operator does not intervene in time, It will seriously affect the production schedule. In addition, because the removal of material by EDM is a process in the microscopic field, the material removal rate is relatively low, which also determines that the processing efficiency of EDM machine tools is low, and it takes several hours or even ten hours to process the cavity. a couple of hours. Therefore, during this long processing time, machine tool operators often dare not leave the workshop (even cannot stay away from the machine tool), but in most of the time (sometimes during the entire processing process) the machine tool discharge state is normal, and there is no need to repair the machine tool Intervention, which has resulted in a serious waste of labor.
此外，由于机床一旦开始加工便需要连续进行直至完成加工任务，因此经常会在机床操作者下班后仍旧在工作，机床操作者如果离开车间，则无法及时掌握机床的状态以及加工任务的进展状况，在出现异常放电状态时无法及时回到车间进行干预，在上一个加工任务完成后也无法及时关闭机床或者更换工件以开始下一个加工任务，这无疑会造成对机床工时的浪费。In addition, once the machine tool starts processing, it needs to continue until the processing task is completed. Therefore, the machine tool operator is often still working after work. If the machine tool operator leaves the workshop, he will not be able to grasp the status of the machine tool and the progress of the processing task in time. When an abnormal discharge state occurs, it is impossible to return to the workshop to intervene in time, and it is impossible to shut down the machine tool or replace the workpiece in time to start the next processing task after the previous processing task is completed. This will undoubtedly cause a waste of machine tool man-hours.

具体实施方式Detailed ways
本实施例的第一方面提供了一种带有蓝牙模块的电火花加工系统，如图1所示，其包括电火花加工机床1(具体为电火花成型加工机床，其利用工具电极在工件上进行放电加工，如成型加工或放电铣削加工)、通讯终端2和蓝牙外设模块5，其中，所述电火花加工机床1具有控制模块11、通讯模块12和蓝牙模块14。其中，所述蓝牙外设模块5可由机床操作者携带，并用于与所述蓝牙模块14进行配对，由此可用于确认机床操作者是否在电火花加工机床1的附近(例如有限的范围内)。在所述电火花加工机床1的工作过程中，当所述蓝牙模块14与所述蓝牙外设模块5脱离配对状态时，所述控制模块11可以确认机床操作者已不在电火花加工机床1的附近，例如实际的情况可能是离开电火花加工机床1甚至离开车间，于是，所述控制模块11便通过所述通讯模块12与所述通讯终端2进行通讯，以便向所述通讯终端2发送信息(例如发送电火花加工机床1的状态信息等)和/或接收所述通讯终端2发来的信息(例如对电火花加工机床1进行控制的指令信息等)。The first aspect of the present embodiment provides a kind of electric discharge processing system with bluetooth module, as shown in Figure 1, it comprises electric discharge machine tool 1 (specifically is electric discharge machine tool, and it utilizes tool electrode on workpiece EDM, such as forming or EDM), communication terminal 2 and Bluetooth peripheral module 5, wherein the EDM machine tool 1 has a control module 11, a communication module 12 and a Bluetooth module 14. Wherein, the bluetooth peripheral module 5 can be carried by the machine tool operator and used to pair with the bluetooth module 14, thus can be used to confirm whether the machine tool operator is near the electric discharge machining machine 1 (for example, within a limited range) . During the working process of the electric discharge machine tool 1, when the bluetooth module 14 and the bluetooth peripheral module 5 are out of the pairing state, the control module 11 can confirm that the machine tool operator is no longer in the electric discharge machine tool 1 Nearby, for example, the actual situation may be to leave the electric discharge machine tool 1 or even leave the workshop, so the control module 11 communicates with the communication terminal 2 through the communication module 12, so as to send information to the communication terminal 2 (for example, sending status information of the electric discharge machine tool 1 , etc.) and/or receiving information from the communication terminal 2 (for example, command information for controlling the electric discharge machine tool 1 , etc.).
其中，所述通讯终端2例如可以是手机、平板电脑、PC机、工作站、或其他智能电器等，具体选择时主要考虑机床操作者在离开电火花加工机床1后是否便于查看。Wherein, the communication terminal 2 can be, for example, a mobile phone, a tablet computer, a PC, a workstation, or other smart electrical appliances, etc. The specific selection mainly considers whether the machine tool operator is easy to check after leaving the EDM machine tool 1 .
本发明的电火花加工系统中，电火花加工机床1能够通过蓝牙模块14和蓝牙外设模块5的配对状态自动检测机床操作者是否离开，并在确认机床操作者离开的情况下自动开启通讯模块12与通讯终端2之间的通讯，使得机床操作者能够在远离机床的情况下通过所述通讯终端2及时掌握机床的动态，从而一方面使机床操作者能够从以往不敢离开车间的束缚状态中解脱出来，在机床执行加工任务的同时，机床操作者可以放心地去执行其他方面的工作，极大地节约了人工；另一方面还能在加工任务紧迫的情况下及时掌握机床的任务进展情况，从而可以在获知机床的加工任务即将完成或已经完成后及时赶往车间进行任务更新，从而有效提高了机床利用率，大大节约了机床工时。In the electric discharge machining system of the present invention, the electric discharge machining machine tool 1 can automatically detect whether the machine tool operator has left through the pairing state of the Bluetooth module 14 and the Bluetooth peripheral module 5, and automatically open the communication module when the machine tool operator is confirmed to leave The communication between 12 and the communication terminal 2 enables the operator of the machine tool to grasp the dynamics of the machine tool through the communication terminal 2 in time when he is far away from the machine tool, so that on the one hand, the operator of the machine tool can avoid the bondage state that he dared not leave the workshop in the past Freed from the process, while the machine tool is performing processing tasks, the machine tool operator can perform other tasks with confidence, which greatly saves labor; on the other hand, it can also grasp the task progress of the machine tool in time when the processing task is urgent , so that after knowing that the processing task of the machine tool is about to be completed or has been completed, it can rush to the workshop to update the task in time, thereby effectively improving the utilization rate of the machine tool and greatly saving the man-hours of the machine tool.
例如，在电火花加工机床1全天候运行的情况下，机床操作者却可以不必实行严格的三班倒的模式，而是可以按时正常上下班，只要随身携带蓝牙外设模块即可，夜班人员例如可以仅在接收到机床需要进行人工干预的信息(如机床出现异常状态或者上一个加工任务完成)的时候前往车间即可。For example, when the EDM machine tool 1 operates around the clock, the machine tool operator does not need to implement a strict three-shift mode, but can go to and from get off work normally on time, as long as he carries the Bluetooth peripheral module with him, night shift personnel such as You can go to the workshop only when you receive information that the machine tool needs manual intervention (such as an abnormal state of the machine tool or the completion of the last processing task).
当机床操作者携带蓝牙外设模块5开启电火花加工机床1时，即在电火花加工机床1开机后，蓝牙模块14可以立即与蓝牙外设模块5完成配对。When the machine tool operator carries the Bluetooth peripheral module 5 and turns on the EDM machine tool 1 , that is, after the EDM machine tool 1 is turned on, the Bluetooth module 14 can be paired with the Bluetooth peripheral module 5 immediately.
优选地，在所述蓝牙模块14与所述蓝牙外设模块5配对成功的情况下，所述控制模块11可以实时(或者间隔一定时间)控制所述蓝牙模块14扫描所述蓝牙外设模块5，在预设的时间内未收到所述蓝牙外设模块5的应答信息时，则可确认为所述蓝牙模块14与所述蓝牙外设模块5脱离配对状态，也即确认为机床操作者离开机床。Preferably, in the case that the Bluetooth module 14 is successfully paired with the Bluetooth peripheral module 5, the control module 11 can control the Bluetooth module 14 to scan the Bluetooth peripheral module 5 in real time (or at regular intervals) , when the response information of the Bluetooth peripheral module 5 is not received within the preset time, it can be confirmed that the Bluetooth module 14 and the Bluetooth peripheral module 5 are out of the pairing state, that is, confirmed as the machine tool operator Get off the machine.
在具体工作时，控制模块11可以通过蓝牙模块14实时(或者间隔一定时间)扫描蓝牙外设模块5，在扫描到蓝牙外设模块5的情况下(也即二者之间保持配对状态时)，则通讯模块12不工作，以免浪费网络资源；只有当蓝牙模块14扫描不到蓝牙外设模块5(例如在预设的时间内未能检测到蓝牙外设5)时，意味着二者之间脱离配对状态，此时蓝牙模块14可以向控制模块11发送信号，以触发通讯模块12与通讯终端2之间的通讯。During specific work, the control module 11 can scan the Bluetooth peripheral module 5 in real time (or at regular intervals) through the Bluetooth module 14, and when the Bluetooth peripheral module 5 is scanned (that is, when the pairing state is maintained between the two) , then the communication module 12 does not work, so as not to waste network resources; only when the bluetooth module 14 scans the bluetooth peripheral module 5 (such as failing to detect the bluetooth peripheral 5 within the preset time), it means that the two At this time, the Bluetooth module 14 can send a signal to the control module 11 to trigger the communication between the communication module 12 and the communication terminal 2 .
优选地，所述蓝牙外设模块5为可穿戴设备，以便于机床操作者携带；优选地，所述可穿戴设备包括手环、手表、吊坠、胸针或胸牌。替代地，所述蓝牙外模块设5也可以是带有蓝牙功能的手机等通讯设备。Preferably, the Bluetooth peripheral module 5 is a wearable device, so as to be easily carried by the machine tool operator; preferably, the wearable device includes a bracelet, watch, pendant, brooch or badge. Alternatively, the bluetooth external module device 5 may also be a communication device such as a mobile phone with a bluetooth function.
优选地，当所述电火花加工机床1接收到任何人工操作时，所述控制模块11便可以终止所述通讯模块12与所述通讯终端2之间的通讯，以免浪费网络资源。显然，当有人工操作电火花加工机床1时，意味着有机床操作者回到车间，此时，无论蓝牙模块14与蓝牙外设模块5是否重新处于配对状态，都可以终止所述通讯模块12与所述通讯终端2之间的通讯，以节约网络资源。Preferably, when the EDM machine tool 1 receives any manual operation, the control module 11 can terminate the communication between the communication module 12 and the communication terminal 2 to avoid wasting network resources. Obviously, when there is a manual operation of the electric discharge machining machine tool 1, it means that the operator of the machine tool returns to the workshop. At this time, no matter whether the Bluetooth module 14 and the Bluetooth peripheral module 5 are in the pairing state again, the communication module 12 can be terminated. Communication with the communication terminal 2 to save network resources.
替代地，在所述通讯模块12与所述通讯终端2之间的进行通讯的过程中，蓝牙模块14仍然可以实时(或者间隔一定时间)扫描蓝牙外设模块5，一旦二者重新配对成功，则蓝牙模块14可以向控制模块11发送信号，以终止所述通讯模块12与所述通讯终端2之间的通讯，以免浪费网络资源。Alternatively, during the process of communicating between the communication module 12 and the communication terminal 2, the Bluetooth module 14 can still scan the Bluetooth peripheral module 5 in real time (or at intervals of a certain time), once the two are re-paired successfully, Then the Bluetooth module 14 can send a signal to the control module 11 to terminate the communication between the communication module 12 and the communication terminal 2, so as to avoid wasting network resources.
作为一种优选实例，所述电火花加工机床1与所述通讯终端2可以在局域网范围内进行互联，从而机床操作者例如可以在机床进行加工的时候离开车间回到设计室中进行其他工作，在通讯终端2收到信息时则前往处理。As a preferred example, the electric discharge machining machine tool 1 and the communication terminal 2 can be interconnected within a local area network, so that the machine tool operator can leave the workshop and return to the design room to perform other work when the machine tool is processing, for example, Then proceed to process when communication terminal 2 receives information.
优选地，如图1所示，本发明的电火花加工系统还可以包括网关3，所述通讯模块12通过所述网关3连接互联网，进而经互联网与所述通讯终端2进行通讯。也即，作为进一步的优选实例，所述电火花加工机床1与所述通讯终端2通过互联网进行互联，从而使得机床操作者与电火花加工机床1之间不再受困于距离的限制，真正实现远程互联。例如，机床操作者可以利用通讯终端2在家中接收电火花加工机床1的相关信息，掌握机床动态，在不需要对机床进行干预的情况下，机床操作者可以不必前往车间，只有当机床停止工作(例如出现异常或者需要更换工件)时，才需要前往车间。这一特点对于晚上加班或周末加班的机床操作者而言更为有利。Preferably, as shown in FIG. 1 , the EDM system of the present invention may further include a gateway 3 , the communication module 12 is connected to the Internet through the gateway 3 , and then communicates with the communication terminal 2 via the Internet. That is, as a further preferred example, the electric discharge machine tool 1 and the communication terminal 2 are interconnected through the Internet, so that the operator of the machine tool and the electric discharge machine tool 1 are no longer limited by the distance, and the real Realize remote interconnection. For example, the machine tool operator can use the communication terminal 2 to receive relevant information about the EDM machine tool 1 at home and grasp the dynamics of the machine tool. In the case of no intervention on the machine tool, the machine tool operator does not need to go to the workshop, only when the machine tool stops working (such as an abnormality or the need to replace the workpiece), it is necessary to go to the workshop. This feature is more beneficial for machine tool operators who work overtime at night or on weekends.
优选地，所述通讯模块12与所述网关3之间的连接方式为无线连接，也即，通讯模块12优选为无线通讯模块，如WI-FI模块、ZigBee模块等，网关3优选为无线网关，如WI-FI网关、ZigBee网关等。采用无线连接的方式容易实现车间的整洁，有利于减少布线工作量和降低成本。Preferably, the connection mode between the communication module 12 and the gateway 3 is a wireless connection, that is, the communication module 12 is preferably a wireless communication module, such as a WI-FI module, a ZigBee module, etc., and the gateway 3 is preferably a wireless gateway , such as WI-FI gateway, ZigBee gateway, etc. The wireless connection is easy to realize the cleanliness of the workshop, which is conducive to reducing the workload of wiring and reducing costs.

The communication terminal 2 is used for communication.
优选地，所述云平台4能够根据所述控制模块11发送的信息内容查询云资源，以便向所述通讯终端2发送附加信息。例如，当控制模块11发送的信息内容包括机床故障信息时，云平台4可以查询云资源，获得与机床故障解除有关的信息，并将这些信息一并发送给通讯终端2，机床操作者在到达车间之前，便可以了解到这些信息，也便于及早做出相关准备。Preferably, the cloud platform 4 can query cloud resources according to the content of the information sent by the control module 11, so as to send additional information to the communication terminal 2. For example, when the information content sent by the control module 11 includes machine tool failure information, the cloud platform 4 can query cloud resources to obtain information related to the removal of the machine tool failure, and send this information to the communication terminal 2 together. This information can be known before the workshop, and it is also convenient to make relevant preparations as soon as possible.
通常，所述电火花加工机床1包括进给单元和供液单元(未示出)，所述进给单元用于提供工具电极和工件之间的相对运动，所述供液单元用于使电火花加工所必须的工作液进行循环，并且用于向工件和工具电极之间的间隙(即极间间隙)内进行强制冲液。Generally, the electric discharge machine tool 1 includes a feed unit and a liquid supply unit (not shown), the feed unit is used to provide relative motion between the tool electrode and the workpiece, and the liquid supply unit is used to make the electric The working fluid necessary for spark machining is circulated and used for forced flushing into the gap between the workpiece and the tool electrode (that is, the inter-electrode gap).
当所述电火花加工机床1在工作过程中出现异常状况时，例如出现放电状态异常(如拉弧和/或短路)，或者出现供液故障时，电火花加工机床1都会暂停放电工作，并且例如给出相应的报警信息，这些情况下，机床操作者必须及时进行处理，以免影响加工进度。特别地，在放电状态异常的情况下，机床虽然停止放电加工，但供液单元通常不会自动停止工作，如果机床操作者不能及时处理的话，则会造成供液单元白白工作而浪费能源。而在供液单元出现供液故障时，进给单元也有可能不会停止工作，但因为无法形成有效的放电加工，便会出现进给单元始终以原地踏步的方式进给，同样是白白工作而浪费能源。优选地，在这些异常状况发生时，所述控制模块11能够将所述异常状况的信息发送给所述通讯终端2，以向机床操作者汇报。并且优选地，所述通讯终端2能够向所述控制模块11发送控制指令，以便使所述控制模块11控制所述进给单元和/或所述供液单元停止工作。When the electric discharge machine tool 1 has an abnormal situation during the working process, such as an abnormal discharge state (such as arcing and/or short circuit), or when a liquid supply failure occurs, the electric discharge machine tool 1 will suspend the discharge work, and For example, corresponding alarm information is given. In these cases, the machine tool operator must deal with it in time to avoid affecting the processing progress. In particular, when the discharge state is abnormal, although the machine tool stops the discharge machining, the liquid supply unit usually does not automatically stop working. If the machine tool operator fails to deal with it in time, the liquid supply unit will work in vain and energy will be wasted. And when there is a liquid supply failure in the liquid supply unit, the feed unit may not stop working, but because the effective discharge machining cannot be formed, the feed unit will always feed in the same way, which is also in vain And waste energy. Preferably, when these abnormal conditions occur, the control module 11 can send the information of the abnormal conditions to the communication terminal 2 to report to the machine tool operator.
