技术领域technical field
本发明涉及一种贾卡驱动系统，特别是涉及一种有源贾卡驱动系统。The invention relates to a jacquard drive system, in particular to an active jacquard drive system.
背景技术Background technique
传统的压电贾卡驱动系统包括贾卡和贾卡驱动装置，其原理和结构由图1和图2示意性地示出。如图1和图2所示，通过贾卡驱动1驱动压电贾卡1，通过贾卡驱动N驱动压电贾卡N。在梳栉上安装有N个贾卡，其中根据需要，N为任意正整数。为便于说明，在图2中仅示出了一个贾卡20’，其中贾卡20’安装在梳栉10’上，贾卡20’的驱动装置通常安装在经编机架上，因此，其和贾卡20’是分离的，两者通过贾卡引线插座30’与贾卡的驱动装置的插槽（未示出）电连接。由于每个贾卡都包括16枚贾卡针（由压电陶瓷片驱动）， 而每枚贾卡针都需要独立的驱动电缆，且通常在每个梳栉上安装有大约200个贾卡，这就造成从驱动装置与贾卡梳栉之间连接有数千根驱动电缆。这种复杂的电缆排布在实际应用中造成诸多不便和限制，如但不限于拆卸维修极为不便，从而极大地影响生产效率，且制约贾卡经编机新的工艺产品的开发。The traditional piezoelectric jacquard driving system includes jacquard and jacquard driving devices, the principle and structure of which are schematically shown in Fig. 1 and Fig. 2 . As shown in FIG. 1 and FIG. 2 , the piezoelectric jacquard 1 is driven by the jacquard driver 1 , and the piezoelectric jacquard N is driven by the jacquard driver N. N jacquards are installed on the comb bar, where N is any positive integer as required. For ease of description, only one jacquard 20' is shown in Fig. 2, wherein the jacquard 20' is installed on the comb bar 10', and the driving device of the jacquard 20' is usually installed on the warp knitting frame, therefore, its It is separated from the jacquard 20 ′, and the two are electrically connected to the slot (not shown) of the jacquard driving device through the jacquard lead socket 30 ′. Since each jacquard includes 16 jacquard needles (driven by piezoelectric ceramic sheets), and each jacquard needle requires an independent drive cable, and usually about 200 jacquards are installed on each bar, This results in thousands of drive cables connected between the slave drives and the jacquard bars. This complex cable arrangement causes a lot of inconvenience and limitations in practical application, such as but not limited to, it is extremely inconvenient to disassemble and maintain, which greatly affects the production efficiency and restricts the development of new craft products of the Jacquard warp knitting machine.
本技术领域仍然需要简单、方便、易拆卸的贾卡驱动系统，以至少部分地解决现有技术中存在的上述问题。There is still a need in the technical field for a jacquard drive system that is simple, convenient, and easy to disassemble, so as to at least partially solve the above-mentioned problems in the prior art.

Fig. 4 is a schematic assembly diagram of the active jacquard drive system of the present invention. It should be understood that, for the sake of description, only two active jacquards 100, 100' are shown in Fig. 4, but the present invention may adopt multiple jacquards identical to the active jacquards 100, 100' as required.
如图4所示，有源贾卡100、100’固定在梳栉500上，有源贾卡100、100’的驱动器上分别设有第一接口95、95’，为有源贾卡100、100’的驱动器提供电源和数据信号的柔性电路板200上设有第二接口295、295’，其中第一接口95通过接插件与第二接口295电连接，而第一接口95’通过接插件与第二接口295’电连接。同时参照图5和图6，这里的数据信号由CPU提供。CPU提供的数据信号以及柔性电路板上的电源信号共同集中在第二接口295、295’中。As shown in Figure 4, the active jacquard 100, 100' is fixed on the comb bar 500, and the drivers of the active jacquard 100, 100' are respectively provided with first interfaces 95, 95', which are active jacquard 100, The flexible circuit board 200 that the driver of 100' provides power and data signals is provided with second interface 295, 295', wherein the first interface 95 is electrically connected with the second interface 295 through the connector, and the first interface 95' is connected through the connector It is electrically connected with the second interface 295'.

优选地，为便于设置第二接口295、295’，首先将柔性电路板200连接至第二接口用线路板（未示出），然后在第二接口用线路板上设置所述第二接口。Preferably, in order to facilitate setting of the second interface 295, 295', the flexible circuit board 200 is first connected to a circuit board for the second interface (not shown), and then the second interface is provided on the circuit board for the second interface.
本发明中的CPU可根据需要为一个或多个，如由N个CPU，即从CPU 1至CPU N，其中一个CPU，如CPU 1，可对应多个驱动器，如驱动器1中驱动器N。The CPU in the present invention can be one or more as required, such as by N CPUs, that is, from CPU 1 to CPU N, wherein one CPU, such as CPU 1, can correspond to multiple drivers, such as driver N in driver 1.

图5为本发明的有源贾卡驱动系统中的带有驱动器于其上的有源贾卡的示意图。如图5所示，有源贾卡100包括贾卡针（包括压电陶瓷片）10、基座20。与现有技术不同的是，有源贾卡100在其后端，即与贾卡针10相对的一端还固定有驱动器。驱动器包括线路板，而为了减小驱动器的体积，线路板由上线路板70和下线路板80组成，而上线路板70和下线路板80电连接，以实现线路板的完整功能。线路板的一端设有第一接口95，以用于通过插接与柔性线路板200上的第二接口295电连接（参见图4）。5 is a schematic diagram of an active jacquard with a driver thereon in the active jacquard driving system of the present invention. As shown in FIG. 5 , the active jacquard 100 includes a jacquard needle (including a piezoelectric ceramic sheet) 10 and a base 20 . Different from the prior art, the active jacquard 100 is also fixed with a driver at its rear end, that is, the end opposite to the jacquard needle 10 . The driver includes a circuit board, and in order to reduce the volume of the driver, the circuit board is composed of an upper circuit board 70 and a lower circuit board 80, and the upper circuit board 70 and the lower circuit board 80 are electrically connected to realize the complete function of the circuit board. One end of the circuit board is provided with a first interface 95 for electrical connection with the second interface 295 on the flexible circuit board 200 through plugging (see FIG. 4 ).
为防止灰尘进入和方便设置第一接口95，有源贾卡还包括容纳线路板的驱动器外壳90。In order to prevent dust from entering and conveniently set the first interface 95, the active jacquard also includes a driver housing 90 for accommodating a circuit board.
有源贾卡100通过固定块40 和滑块30以及紧固件，如第一螺钉50固定至梳栉的凹槽（未示出）中。这种固定方式对本领域的技术人员而言是已知的，在此不予赘述。The active jacquard 100 is fixed into the groove (not shown) of the comb bar through the fixing block 40 and the sliding block 30 and fasteners, such as the first screw 50 . This fixing method is known to those skilled in the art and will not be repeated here.
为了方便将贾卡100（仅为举例，其它贾卡相同）固定至梳栉上或从梳栉上拆下，上线路板70以及驱动器罩壳90的与第一螺钉50相应的位置设有安装孔，优选腰型孔，以方便对第一螺钉50的操作。In order to facilitate fixing the jacquard 100 (just for example, other jacquards are the same) to the comb bar or remove it from the comb bar, the position corresponding to the first screw 50 of the upper circuit board 70 and the driver cover 90 is provided with a mounting bracket. Holes, preferably waist-shaped holes, to facilitate the operation of the first screw 50.

应该理解，线路板并非一定要做成上线路板70和下线路板80的形式，也可以仅采用单一线路板，只要该线路板能实现所需的所有控制功能。It should be understood that the circuit boards do not have to be in the form of the upper circuit board 70 and the lower circuit board 80, and only a single circuit board can be used as long as the circuit board can realize all required control functions.
线路板上的各个功能电路或模块以及它们之间的相互连接和作用关系对本领域的技术人员而言是已知的，在此不予赘述。Various functional circuits or modules on the circuit board and their interconnections and functional relationships are known to those skilled in the art, and will not be repeated here.
本发明的有源贾卡控制系统在具体操作时，只需将第一接口95和第二接口295通过插接电连接即可。柔性线路板与有源贾卡配合后，保持松弛状态，从而便于有源贾卡的装配和拆卸。During specific operation of the active jacquard control system of the present invention, it is only necessary to electrically connect the first interface 95 and the second interface 295 through plugging. After the flexible circuit board is mated with the active jacquard, it remains in a relaxed state, thereby facilitating the assembly and disassembly of the active jacquard.
由于驱动器工作时会产生热量，可在梳栉和贾卡基座上设置通气孔，为梳栉通风冷却，防止梳栉因热膨胀而产生变形。Since the driver will generate heat during operation, vent holes can be set on the bar and the jacquard base to ventilate and cool the bar, and prevent the bar from being deformed due to thermal expansion.
本发明的有源贾卡控制系统采用有源贾卡，将驱控器直接设置于贾卡上，完全消除了现有贾卡驱动电路板与贾卡之间的数千根驱动电缆，从而精简了系统接线，贾卡提花梳栉可像普通导纱梳栉一样进行拆卸后穿纱，且在机台安装位置的设计上也可像普通梳栉那样不受限制。The active jacquard control system of the present invention adopts active jacquard, and the drive controller is directly arranged on the jacquard, which completely eliminates thousands of drive cables between the existing jacquard drive circuit board and the jacquard, thereby simplifying the After connecting the system, the Jacquard jacquard bar can be disassembled like a common yarn guide bar and then threaded, and the design of the machine installation position can also be unrestricted like a common bar.
基于对本发明优选实施方式的描述，应该清楚，由所附的权利要求书所限定的本发明并不仅仅局限于上面说明书中所阐述的特定细节，未脱离本发明宗旨或范围的对本发明的许多显而易见的改变同样可能达到本发明的目的。Based on the description of the preferred embodiments of the present invention, it should be clear that the present invention defined by the appended claims is not limited to the specific details set forth in the description above, and there are many aspects of the present invention that do not depart from the spirit or scope of the present invention.
