技术领域technical field
本发明涉及LED芯片分选技术领域，具体是涉及一种多台LED分选机联机自动化作业系统及方法。The invention relates to the technical field of LED chip sorting, in particular to an online automatic operation system and method for multiple LED sorting machines.
背景技术Background technique
一张LED晶圆片经过外延生长，图形加工，减薄切割后形成一颗颗LED芯片承载在蓝膜上，因外延生长的均匀性差异等原因，每颗芯片的光电特性不尽相同，经过LED点测机测试后，需要根据客户的需求，按照不同光电参数区间分类形成不同的BIN等级，然后使用LED芯片分选机将相同BIN等级的芯片集中在一张蓝膜上形成BIN供使用。After epitaxial growth, pattern processing, thinning and cutting, an LED wafer is formed into individual LED chips carried on the blue film. Due to differences in the uniformity of epitaxial growth and other reasons, the photoelectric characteristics of each chip are different. After the LED point tester is tested, it is necessary to form different BIN levels according to different photoelectric parameter intervals according to the customer's needs, and then use the LED chip sorter to gather chips of the same BIN level on a blue film to form a BIN for use.
现有的分选机每台配备1个圆片料盒和7个或8个BIN料盒，最大可加工的BIN等级为150或175个，BIN等级和BIN数量均会受到限制，而且每台分选机的料盒为当前分选机专用独有。Each existing sorting machine is equipped with 1 wafer magazine and 7 or 8 BIN magazines. The maximum processable BIN level is 150 or 175. Both the BIN level and the number of BINs will be limited, and each The material box of the sorting machine is unique to the current sorting machine.
在分选作业过程中，若遇到切机加工其它尺寸和图形的LED产品，需要将分选机内所有的BIN料盒内BIN制品结清，再重新配置设置参数加工下一产品，被结清出来的未排满的半成品BIN片部分颗数较少需要重排返工或是报废处理，造成返工和物料浪费比较多。During the sorting operation, if the cutting machine processes LED products of other sizes and graphics, it is necessary to clear all the BIN products in the BIN material boxes in the sorting machine, and then reconfigure and set the parameters to process the next product. The number of unfilled semi-finished BIN chips that have been cleared out is less and needs to be rearranged and reworked or scrapped, resulting in more rework and material waste.
其中，上述提及的缩写具体为：Among them, the abbreviations mentioned above are specifically:
LED：发光二极管；LED: light emitting diode;
BIN：LED芯片根据光电参数进行分类后形成的不同等级的统称;BIN: The general term for different grades of LED chips formed after they are classified according to the photoelectric parameters;
Wafer：LED晶圆片。Wafer: LED wafer.

Among them, the mode in which a transfer material box is placed on the transfer platform is preferred, and the BIN pieces taken out from the rack platform are transferred to the transfer BIN material box.

作为分选机的排布设置的优选方式，如图2中所示，分布设置在所述传输平台的两侧，在一定程度上减少传输路径，提高工作效率。As an optimal arrangement of sorting machines, as shown in Figure 2, they are arranged on both sides of the transfer platform, which reduces the transfer path to a certain extent and improves work efficiency.
优选地，分选机中只设置一个圆片料盒和一个BIN料盒。Preferably, only one wafer magazine and one BIN magazine are set in the sorting machine.

As another embodiment, a feeding device can be directly set between the transfer platform and the sorting machine, and the BIN pieces are fed from the transfer box to the corresponding sorting machine.
本发明进一步公开了一种多台LED分选机联机自动化作业方法，该方法包括：The present invention further discloses an online automatic operation method for multiple LED sorting machines, the method comprising:
确定目标BIN片，将目标BIN片从料架平台转移至一传输平台；Determine the target BIN piece, and transfer the target BIN piece from the shelf platform to a transmission platform;
目标BIN片在传输平台上传输至相应分选机位置；The target BIN piece is transferred to the corresponding position of the sorting machine on the transfer platform;
分选机被配置为从传输平台中获取目标BIN片。The sorting machine is configured to obtain target BIN pieces from the transfer platform.
优选地，确定目标BIN片的方法为：确定传输平台的位置，确定分选机的位置，以上述位置配置目标BIN片。Preferably, the method for determining the target BIN slice is: determining the position of the transmission platform, determining the position of the sorting machine, and configuring the target BIN slice at the above position.
根据LED芯片的光电参数分为不同的BIN等级；本领域的技术人员应当知道，为了防止蓝膜变形，按照制备工艺，在wafer扫描准备挑选时，BIN等级的挑选顺序为：按照待挑选的BIN颗数，从少到多的顺序依次进行挑选。According to the photoelectric parameters of the LED chip, it is divided into different BIN levels; those skilled in the art should know that in order to prevent the deformation of the blue film, according to the preparation process, when the wafer is scanned for selection, the selection order of the BIN level is: according to the BIN to be selected The number of pieces is selected in order from least to most.
当分选机加工工位未占用的第一等级的目标BIN片时，直接分配到对应的分选机的第一等级的缓冲BIN料盒中；When the first-level target BIN chips that are not occupied by the processing station of the sorting machine are directly allocated to the first-level buffer BIN material box of the corresponding sorting machine;
当分选机加工工位被占用的第一等级的目标BIN片时，监测同一等级的其他分选机的其它加工工位是否加工完成，并按照其他分选机的加工工位的上一BIN等级颗数进行排序，优先加工所述上一BIN等级颗数最多的加工工位，直到分选机加工工位对应的BIN等级全部加工完毕，循环加工下一等级的目标BIN片。When the processing station of the sorting machine is occupied by the target BIN piece of the first level, monitor whether other processing stations of other sorting machines of the same level have finished processing, and follow the previous BIN level of the processing stations of other sorting machines The number of pieces is sorted, and the processing station with the largest number of pieces in the previous BIN grade is processed first, until the BIN grades corresponding to the processing stations of the sorting machine are all processed, and the target BIN pieces of the next grade are processed circularly.
更具体的，假设满BIN颗数是n，一般的需要返工或颗数较少需要报废的BIN颗数是n，为避免BIN制品的返工及报废，在wafer扫描准备挑拣时，默认的BIN等级的挑拣顺序是按照颗数的多少，由少到多依次进行。首先将其它挑拣工位未占用的BIN片使用自动物料系统分配至当前工位的缓冲BIN料盒，当本机台需要加工占用的BIN片时，系统监测其它工位的是否加工完成，并按照当前工位加工的前一BIN等级颗数的多少决定排队次序，前一BIN等级颗数多的具备优先级，优先级落后的跳过当前占用等级加工下一等级，下一等级加工完后再次排队请求占用BIN等级片，依次循环，直到完成占用BIN等级加工。More specifically, assuming that the number of full BINs is n, the number of BINs that generally need to be reworked or have a small number of BINs that need to be scrapped is n, in order to avoid rework and scrapping of BIN products, when the wafer is scanned and ready to be picked, the default picking order of the BIN level is based on the number of pieces, from less to more. First, use the automatic material system to distribute the unoccupied BIN pieces of other picking stations to the buffer BIN material box of the current station. When the machine needs to process the occupied BIN pieces, the system monitors whether the processing of other stations is completed, and follows The number of pieces of the previous BIN level processed by the current station determines the queuing order. Those with more pieces in the previous BIN level have priority, and those with lower priority skip the current occupied level to process the next level. After the next level is processed, go back The queuing requests occupy BIN level slices, and cycle in turn until the occupied BIN level processing is completed.
需要说明的是，当监测排队等待占用的BIN片时间过长时，计算占用工位加工完占用BIN等级后的颗数，若颗数≥n，等待的工位可以取新的空BIN片进行排晶，占用BIN等级加工完后可以提前结清颗数下料。What needs to be explained is that when monitoring the occupied BIN slices waiting in line for too long, calculate the number of pieces after the occupied station has finished processing the occupied BIN level, if the number of pieces ≥ n, the waiting station can take a new empty BIN chip for crystal arrangement, and the number of chips can be settled in advance after the occupied BIN level is processed.
优选地，分选机被配置获取目标BIN片的方法为：从传输平台中的中转料盒中抓取目标BIN片，放置于分选机配置的料盒中。Preferably, the method in which the sorting machine is configured to obtain the target BIN slices is as follows: grabbing the target BIN slices from the transfer magazine on the transfer platform, and placing them in the magazines configured by the sorting machine.
优选地，料架平台从上一平台中补充BIN片。Preferably, the shelf platform is replenished with BIN pieces from the previous platform.
优选地，分选机中配置设置一个BIN料盒；可以将BIN等级分的更细，使BIN等级的划分不受限制；而且可以快速完成BIN等级的加工，提高生产效率；此外，在切换品种时减少半成品BIN片的返工和报废，节约了加工成本。Preferably, a BIN material box is configured in the sorting machine; the BIN grade can be divided into finer, so that the division of the BIN grade is not restricted; and the processing of the BIN grade can be quickly completed to improve production efficiency; in addition, when switching varieties The rework and scrapping of semi-finished BIN chips can be reduced in time, and the processing cost can be saved.
如图2所示，本发明将机台内的BIN料盒进行缩减集中至料架，分选机后方设置滑轨和中转料盒转递BIN片，滑轨末端与料架间设置机械手用于料架与中转料盒间转移BIN片，中转料盒与分选机台内料盒的BIN片转移使用分选机内配备的滑轨及夹爪。分选机每次挑拣动作前，由料架端电脑程序预先将分选机优先使用的BIN片分配至分选机BIN料盒中，分选机挑拣过程中由料架端电脑及时分配补充更换BIN片。As shown in Figure 2, the present invention reduces the BIN material boxes in the machine and concentrates them on the material rack. A slide rail and a transfer material box are set behind the sorting machine to transfer the BIN pieces, and a manipulator is set between the end of the slide rail and the material rack for The BIN pieces are transferred between the material rack and the transfer box, and the transfer of the BIN pieces between the transfer box and the box in the sorting machine uses the slide rails and grippers equipped in the sorting machine. Before each sorting action of the sorting machine, the computer program at the rack end will pre-allocate the BIN slices that the sorting machine will use preferentially to the BIN material box of the sorting machine. During the sorting process, the computer at the rack end will allocate and replace them BIN slice.
本发明打破了常规的分选机BIN片单机独有的使用方法，通过本方案可以实现相同品种的产品共用BIN片。另外本方案通过在机台后方设置滑轨及中转料盒的方式实现了分选作业的自动化流水线。The present invention breaks through the unique usage method of the conventional sorting machine BIN chip single machine, and can realize that the products of the same variety share the BIN chip through this scheme. In addition, this scheme realizes the automatic assembly line of sorting operation by setting slide rails and transfer boxes behind the machine.
本发明由于BIN片集中在料架，产品的分BIN数量不会受到先前分选机最大150个BIN等级的限制，BIN等级数量可以根据客户需求无限制增加；In the present invention, because the BIN pieces are concentrated on the material rack, the number of BINs of the product will not be limited by the maximum 150 BIN levels of the previous sorting machine, and the number of BIN levels can be increased without limit according to customer needs;
相同的品种可以共用BIN片，通过料架端电脑的分配可以实现快速的完成特定BIN等级的加工量，从而加快订单完成率，提高效率；The same variety can share BIN slices, and through the distribution of the computer at the rack end, the processing volume of a specific BIN level can be quickly completed, thereby speeding up the order completion rate and improving efficiency;
相同的品种可以共用BIN片，这样在切换品种时可以大量减少半成品BIN的返工和报废，节约加工成本；The same variety can share BIN chips, which can greatly reduce the rework and scrapping of semi-finished BINs when switching varieties, and save processing costs;
通过在分选机后方设置滑轨和中转料盒，可以实现分选机自动补充BIN片和收集满料，减少操作工工作量，提高分选作业的自动化程度。By setting slide rails and transfer boxes behind the sorting machine, the sorting machine can automatically replenish BIN chips and collect full materials, reduce the workload of operators, and improve the automation of sorting operations.
