Description

Technical Field

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

[0002] Wireless Jacquard refers to a device that integrates a driver inside the Jacquard comb. This driver can be used to drive the piezoelectric ceramic part inside the Jacquard comb to swing, thereby causing the yarn guide needle to swing together to achieve the jacquard yarn guiding action, and thus achieve the purpose of removing the cable on the tail of the Jacquard comb.

[0003] Chinese utility model patent (application number: 201520150649.1, publication number: CN204496248U) discloses an embedded electronic Jacquard comb for jacquard control of warp knitting machines. However, it still has shortcomings in actual use: Currently, as the number of guide needles on a Jacquard comb increases, specifically, the number of guide needles on a Jacquard comb can reach 24 or 32 needles. Each guide needle requires a corresponding piezoelectric ceramic element to drive it. This requires the output end of the drive circuit board to be equipped with 24 or 32 conductive contacts. Due to the limited area of ​​the drive circuit board, the spacing between these conductive contacts is small. If only one connector is used to connect to all the conductive contacts, it is easy to solder the wrong points during the soldering process. On the other hand, if only one connector is used on the drive circuit board, the input end of the connector must also be equipped with the same number of conductive contacts, which has certain processing difficulties in actual production. Utility Model Content

[0004] This utility model provides a wireless jacquard device and a driver for the wireless jacquard device. Its main purpose is to overcome the defect that in existing wireless jacquard devices, when the driver is equipped with only one connector, there are too many solder joints and the spacing between the solder joints is small, which makes it easy to solder the wrong solder joints during the soldering process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: In a first aspect, a driver for a wireless jacquard device having a plurality of piezoelectric ceramic elements is provided. The driver includes at least one drive circuit board, a first connector disposed on the drive circuit board, and a second connector disposed on the drive circuit board. The drive circuit board is used to drive the corresponding piezoelectric ceramic elements to oscillate. The first connector is used to electrically connect at least one piezoelectric ceramic element to the output terminal of the corresponding drive circuit board. The second connector is used to electrically connect at least one piezoelectric ceramic element to the output terminal of the corresponding drive circuit board. When the drive circuit board drives the piezoelectric ceramic elements to oscillate, the drive circuit board drives at least one corresponding piezoelectric ceramic element to oscillate through the first connector, and the drive circuit board drives at least one corresponding piezoelectric ceramic element to oscillate through the second connector.

[0006] In one possible implementation, the first connector is disposed on the upper surface of the drive circuit board and electrically connected to the output terminal of the drive circuit board.

[0007] In one possible implementation, the second connector is disposed on the lower surface of the drive circuit board and electrically connected to the output terminal of the drive circuit board.

[0008] In one possible implementation, the driving circuit board includes a printed circuit board and a multi-channel driving circuit. The output terminal of the driving circuit board has a plurality of first conductive contacts arranged on the upper surface of the printed circuit board. The first conductive contacts are electrically connected to the corresponding driving circuits. The input terminal of the first connector is soldered to the corresponding first conductive contact. When the driving circuit board drives the piezoelectric ceramic element to swing, the driving circuit outputs a high level or a low level through the first conductive contact.

[0009] In one possible implementation, the output terminal of the drive circuit board has a plurality of second conductive contacts arranged on the lower surface of the printed circuit board. The input terminal of the second connector is soldered to the corresponding second conductive contact. The second conductive contact is electrically connected to the corresponding drive circuit. When the drive circuit board drives the piezoelectric ceramic element to swing, the drive circuit outputs a high level or a low level through the second conductive contact.

[0010] In one possible implementation, the output of the first connector is coupled to a piezoelectric ceramic element corresponding to a portion of the wireless jacquard device to achieve an electrical connection, and the second connector is coupled to a piezoelectric ceramic element corresponding to another portion of the wireless jacquard device to achieve an electrical connection.

[0011] In one possible implementation, the number of the first connector is 1 to 2, and the number of the second connector is 1 to 2.

[0012] A wireless jacquard weaving device includes a comb base, a plurality of piezoelectric ceramic elements disposed on the comb base, a plurality of yarn guide needles, and at least one driver. The driver is used to drive the corresponding piezoelectric ceramic elements to swing, so that the piezoelectric ceramic elements drive the corresponding yarn guide needles to swing together. The driver is characterized in that the driver is detachably disposed on the comb base, and the driver is the aforementioned driver.

[0013] In one possible implementation, the driver includes at least one drive circuit board, a first connector disposed on the drive circuit board, and a second connector disposed on the drive circuit board. The wireless jacquard device has a first plug and a second plug, the first plug being adapted to the first connector, and the second plug being adapted to the second connector. When using the wireless jacquard device, the first plug is installed on the first connector in a plug-in manner to achieve electrical connection, and the second plug is installed on the second connector in a plug-in manner to achieve electrical connection.

[0014] In one possible implementation, the number of the first connectors is 1 to 2, and the number of the second connectors is 1 to 2.

[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 a first connector and a second connector on the drive circuit board, when the number of the first connector and the second connector is one, the number of solder points on a single connector is half of the original number. When the number of the first connector and the second connector is two, the number of solder points on a single connector is one-quarter of the original number. This makes it possible to set fewer solder points on the first connector and the second connector than before, thereby facilitating the electrical connection between the first connector, the second connector and the drive circuit board.
