Description

Technical Field

[0001] This utility model relates to the field of wireless jigs, and in particular to a wireless jig and a driving device for the wireless jig. Background Technology

[0002] Wireless Jacquard refers to a Jacquard comb with an integrated drive circuit board. This drive circuit board can be used to drive the piezoelectric ceramic element inside the Jacquard comb to swing, thereby causing the piezoelectric ceramic element to drive the yarn guide needle to swing together, so as to realize the jacquard yarn guiding action.

[0003] Currently, with the increase in the number of guide needles, a Jacquard comb can have 16, 24, or 32 guide needles. In order to improve the integration of the drive circuit board, a driver is set on the drive circuit board, which acts as the drive circuit, thereby replacing multiple drive circuits with one driver to reduce the space occupied by the drive circuit. However, in actual use, there are still the following shortcomings: after setting the driver, multiple corresponding current-limiting resistors need to be set accordingly. Due to the limited area of ​​the drive circuit board, there is not enough space to accommodate all the current-limiting resistors on one surface at the same time. Utility Model Content

[0004] This utility model provides a wireless jacquard and a driving device for the wireless jacquard. Its main purpose is to overcome the defect that due to the limited area of ​​the driving circuit board, it is impossible to accommodate all current-limiting resistors on one surface at the same time because there is not enough space.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: In a first aspect, this disclosure provides a driving device for a wireless jacquard, comprising at least one driving circuit board, multiple conductive units, at least one driver, and at least two sets of current-limiting resistors. The driver is integrally disposed on the driving circuit board, the conductive units are disposed on the output terminals of the driving circuit board, at least one set of the current-limiting resistors is disposed on the upper surface of the driving circuit board, and another set of the current-limiting resistors is disposed on the lower surface of the driving circuit board. One end of the current-limiting resistor is electrically connected to the corresponding conductive unit, and the other end of the current-limiting resistor is electrically connected to the driver. When the driving circuit board drives the piezoelectric ceramic element of the wireless jacquard to swing, the driver outputs at least one electrical signal according to the pattern process data. The electrical signal drives the piezoelectric ceramic element of the wireless jacquard to swing through the corresponding conductive unit, so that the piezoelectric ceramic element drives the corresponding yarn guide needle to swing together.

[0006] In one possible implementation, the total number of the current-limiting resistors is equal to the total number of the piezoelectric ceramic elements.

[0007] In one possible implementation, the driver is a microcontroller or a chip.

[0008] In one possible implementation, the total number of the current-limiting resistors is 1 to 64.

[0009] In one possible implementation, the electrical signal is either high or low.

[0010] In one possible implementation, the current-limiting resistor is adapted to the corresponding piezoelectric ceramic element, and the current-limiting resistor is used to prevent excessive current in the event of a short circuit.

[0011] In one possible implementation, the conductive unit includes at least two sets of connectors and at least two sets of conductive contacts adapted to the connectors. At least one set of the connectors is disposed on the upper surface of the drive circuit board, and the other set of the connectors is disposed on the lower surface of the drive circuit board. At least one set of the conductive contacts is disposed on the upper surface of the drive circuit board, and the other set of the conductive contacts is disposed on the lower surface of the drive circuit board. The input terminal of the connector is electrically connected to the corresponding current-limiting resistor through the corresponding conductive contact.

[0012] In one possible implementation, the connector and the driver are electrically connected via corresponding conductive contacts.

[0013] In one possible implementation, the connector includes at least one socket and at least one plug. When the input end of the socket is electrically connected to the conductive unit, the output end of the plug is electrically connected to the input end of the piezoelectric ceramic element. The plug achieves electrical connection by being inserted into the socket.

[0014] A wireless jacquard includes at least one comb base, a plurality of piezoelectric ceramic elements arranged on the comb base, a plurality of yarn guide needles arranged on the front of the comb base, and at least one driving device. The output end of the driving device is coupled to the input end of the piezoelectric ceramic elements to achieve electrical connection. The driving device is used to drive the piezoelectric ceramic elements to swing, and the piezoelectric ceramic elements are used to drive the corresponding yarn guide needles to swing together. The driving device is the aforementioned driving device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a simple structure and strong practicality. By setting at least one set of current-limiting resistors on the upper surface of the drive circuit board and another set of current-limiting resistors on the lower surface of the drive circuit board, the space on the upper and lower surfaces of the drive circuit board is effectively utilized to set the current-limiting resistors, making the position of the current-limiting resistors on the drive circuit board more reasonable and facilitating the arrangement of the wiring between the driver and the current-limiting resistors.

In this embodiment, at least one set of connectors 211 is disposed on the upper surface of the driving circuit board 200, and the other set of connectors 211 is disposed on the lower surface of the driving circuit board 200. At least one set of conductive contacts 210 is disposed on the upper surface of the driving circuit board 200, and the other set of conductive contacts 210 is disposed on the lower surface of the driving circuit board 200.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, by setting at least one set of current-limiting resistors 204 on the upper surface of the driving circuit board 200 and another set of current-limiting resistors 204 on the lower surface of the driving circuit board 200, the space on the upper and lower surfaces of the driving circuit board 200 is effectively utilized to set the current-limiting resistors 204, making the position of the current-limiting resistors 204 on the driving circuit board 200 more reasonable and facilitating the arrangement of the wiring between the driver 203 and the current-limiting resistors 204.

[0028] Example 2, refer to Figure 3 and Figure 4 The difference between this second embodiment and the first embodiment is that the connector 211 includes at least one socket 212 and at least one plug 213. When the input end of the socket 212 is electrically connected to the conductive unit 202, the output end of the plug 213 is electrically connected to the input end of the piezoelectric ceramic element 101.

Specifically, 16 current limiting resistors 204 can be set on the upper surface of the drive circuit board 200 and 16 current limiting resistors 204 can be set on the lower surface of the drive circuit board 200.

[0036] Reference Figure 1 , Figure 2 and Figure 3 For example, when the yarn guide needle 102 has 64 needles, 64 piezoelectric ceramic elements 101 are required, which in turn requires 64 current-limiting resistors. Specifically, 32 current-limiting resistors 204 can be set on the upper surface of the drive circuit board 200, and 32 current-limiting resistors 204 can be set on the lower surface of the drive circuit board 200. When the yarn guide needle 102 has 24 needles, 24 piezoelectric ceramic elements 101 are required, which in turn requires 24 current-limiting resistors 204.
