Description

[0001] This invention relates to the field of piezoelectric jacquards, and in particular to a piezoelectric jacquard with a drive circuit board. Background Technology

[0002] Piezoelectric jacquards utilize the deformation properties of piezoelectric ceramic plates when energized to drive the oscillation of yarn guide needles, thus completing the jacquard weaving action. Existing piezoelectric jacquard wiring structures mostly use external, independent terminal connections, with signal input lines, cascaded output lines, and piezoelectric ceramic drive lines connected separately externally, lacking an integrated layout structure.

[0003] The distributed external cabling method has obvious drawbacks, resulting in messy wiring and tangled cables. During long-term high-frequency vibration operation of the warp knitting machine, external cables are prone to pulling, loosening, detachment, and breakage, leading to poor signal contact, jacquard misalignment, and other malfunctions. Furthermore, the distributed power connection structure involves cumbersome disassembly and assembly procedures; equipment maintenance and component replacement require disassembling cables one by one, resulting in low maintenance efficiency and impacting equipment production stability and the quality of finished fabrics. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A piezoelectric jacquard with a driving circuit board includes: a jacquard yarn guide block, a driving circuit board, a first socket, and a first conductive cable. The drive circuit board is mounted on the piezoelectric ceramic plate of the Jacquard yarn guide needle block. The upper part of the drive circuit board is provided with a first conductive contact, a second conductive contact, and a first drive circuit. The output terminal of the first drive circuit is electrically connected to the first conductive contact. The first socket is fixedly mounted on the first conductive contact, and the output terminal of the first socket is electrically connected to the first conductive contact. The first conductive cable has a first plug integrated at its front end, and the rear end of the conductive line is electrically connected to the second conductive contact. A first electrical signal is input to the first driving circuit through the first conductive contact, and the first driving circuit outputs a second electrical signal through the second conductive contact.

[0006] Furthermore, the rear end of the first conductive cable is soldered onto the second conductive contact.

[0007] Furthermore, a second socket is provided at the lower part of the drive circuit board, and the input terminal of the second socket is electrically connected to the output terminal of the first drive circuit.

[0008] Furthermore, a second conductive cable is welded to the tail of the piezoelectric ceramic sheet, and a second plug is provided on one end of the first conductive cable. The second plug is plugged into the second socket to realize electrical connection with the first driving circuit. The second electrical signal output by the first driving circuit is transmitted to the piezoelectric ceramic sheet through the second socket, the second plug and the second conductive cable.

[0009] Furthermore, a tail clip is provided on the rear part of the Jacquard guide needle block, and a first slot and a second slot are respectively provided on the upper outer surface of the tail clip. A portion of the first conductive cable extends through the first slot toward the outside of the first slot, and the opening of the first socket is provided in the second slot.

[0010] Furthermore, the first slot has a convex shape.

[0011] Furthermore, the second slot is rectangular in shape.

[0012] Furthermore, the length of the first conductive cable is greater than the width of the tail clip.

[0023] Reference Figure 1 and Figure 4 The upper part of the drive circuit board 11 is provided with a first conductive contact 4, a second conductive contact 5, and a first drive circuit 6. The output end of the first drive circuit 6 is electrically connected to the first conductive contact 4. The first socket 1 is fixedly installed at the first conductive contact 4 to achieve stable conduction. The front end of the first conductive cable 2 integrates a first plug 7, which can be quickly connected to external devices. The rear end of the first conductive cable 2 is fixedly connected to the second conductive contact 5. During operation, the external first electrical signal is input to the first drive circuit 6 through the first socket 1 and the first conductive contact 4. The first drive circuit 6 outputs an adapted second electrical signal according to the first electrical signal, and simultaneously outputs it outward through the second conductive contact 5 and the first conductive cable 2.

[0024] Reference Figure 1 and Figure 4 The first conductive contact 4, the second conductive contact 5, the first driving circuit 6, the first socket 1, and the first conductive cable 2 are integrated on the upper part of the driving circuit board 11. The first conductive cable 2, the first plug 7, and the first socket 1 form an integrated signal output channel and a signal input channel, replacing the traditional external distributed power connection structure, and the wiring is neat and orderly.

[0025] Reference Figure 1 and Figure 4 The first electrical signal is input through the first socket 1 and the first conductive contact 4, and after being processed by the first drive circuit 6, the second electrical signal is output through the second conductive contact 5, which can meet the needs of multiple sets of piezoelectric Jacquard cascade assembly. The rear end of the first conductive cable 2 is fixedly connected to the second conductive contact 5 by welding, which ensures a firm connection, good vibration resistance, and can effectively avoid faults such as loose wiring, broken wires, and abnormal signals during long-term operation.

[0026] Reference Figure 1 and Figure 4 A second socket 8 is provided at the lower part of the drive circuit board 11. The piezoelectric ceramic sheet 9 is connected to the second socket 8 through the second plug 13 at the end of the second conductive cable 3, so as to achieve quick disassembly and assembly without cumbersome soldering operations, effectively improving the efficiency of equipment assembly, maintenance and replacement.

[0027] Reference Figure 1 and Figure 4 By setting the second conductive cable 3, the first socket 1, the first conductive cable 2, and the first plug 7, the signal input, signal cascade output, and piezoelectric ceramic driving functions are integrated on a single drive circuit board 11. The structure is compact, suitable for the narrow installation space of piezoelectric jacquard, reduces external line signal interference, improves signal transmission stability, ensures accurate execution of jacquard actions, reduces fabric weaving defect rate, and is suitable for long-term continuous production conditions of warp knitting machines.

[0028] Reference Figure 1 and Figure 4 The first socket 1 and the first conductive contact 4 are welded and fixed together as a whole, which is structurally robust, provides stable conductivity, and has both fixing and conductive functions. The first socket 1 and the first conductive cable 2 are arranged on the upper exposed position of the drive circuit board 11 without structural obstruction, allowing for easy disassembly, assembly, and maintenance without interference.

[0029] Reference Figure 1 and Figure 4 The second socket 8 and the second plug 13 adopt a tight-fitting plug-in structure, which has good anti-vibration and anti-dislodgement effect and avoids the interface loosening caused by equipment vibration.

[0030] Example 2, refer to Figure 1 and Figure 4 The difference between this second embodiment and the first embodiment is that a tail clip 14 is provided on the rear part of the Jacquard guide needle block 10. The upper outer surface of the tail clip 14 is provided with a first slot 15 and a second slot 16 spaced apart. A portion of the first conductive cable 2 passes through the first slot 15 and extends outward from it. The opening of the first socket 1 is located within the second slot 16. The first slot 15 is convex in shape, and the second slot 16 is rectangular in shape.

[0031] Reference Figure 1 and Figure 4 The rear end of the first conductive cable 2 is fixed to the surface of the second conductive contact 5 by soldering. The soldered structure has low contact resistance and stable conduction, ensuring long-term stable signal transmission.

[0032] Reference Figure 1 and Figure 4 A second socket 8 is fixedly mounted on the lower part of the drive circuit board 11. The input end of the second socket 8 is electrically connected to the output end of the first drive circuit 6, serving as a dedicated drive docking port for the piezoelectric ceramic sheet 9. A second conductive cable 3 is welded and fixed to the tail of the piezoelectric ceramic sheet 9. A second plug 13 is provided at the end of the second conductive cable 3. The second plug 13 can be directly plugged into the second socket 8, realizing a quick electrical connection between the first drive circuit 6 and the piezoelectric ceramic sheet 9, which is convenient for assembly and disassembly and has high efficiency.

[0033] Reference Figure 1 and Figure 4 An external first electrical signal is input into the first driving circuit 6 through the first conductive contact 4. After signal processing, the first driving circuit 6 outputs a second electrical signal. One signal is cascaded through the second conductive contact 5 and the first conductive cable 2, while the other signal is output through the lower second socket 8, and then transmitted to the piezoelectric ceramic plate 9 via the second plug 13 and the second conductive cable 3. This drives the piezoelectric ceramic plate 9 to deform, thereby driving the yarn guide needle 40 to complete the jacquard weaving action. The first socket 1 and the first conductive cable 2 are located in the exposed area on the upper part of the driving circuit board 11, without structural obstruction, making disassembly and maintenance convenient. The first socket 1 and the first conductive contact 4 are welded and fixed, resulting in a stable overall structure. The second socket 8 and the second plug 13 are tightly connected, effectively resisting equipment vibration and preventing the interface from loosening.

[0034] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0035] Example 3, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The difference between this embodiment 3 and embodiment 1 is that the driving circuit board 11 includes a first printed circuit board 30 and a second printed circuit board 31. The first printed circuit board 30 and the second printed circuit board 31 are stacked in parallel to each other, and the overall structure is flat and compact with high space utilization.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The upper surface of the first printed circuit board 30 integrates a first driving circuit 6, which is used to output the driving signal required to drive the piezoelectric ceramic sheet 9. The lower surface of the first printed circuit board 30 is provided with two sets of third PCB edge pad contacts 34. The two sets of third PCB edge pad contacts 34 are arranged parallel to each other and spaced apart, forming two independent signal channels. The lower surface of the second printed circuit board 31 is provided with a second driving circuit 32, which works with the first driving circuit 6 to realize multi-channel signal coordinated driving. The left and right edges of the lower surface of the second printed circuit board 31 are respectively provided with a set of fourth PCB edge pad contacts 33. The two sets of fourth PCB edge pad contacts 33 are also arranged parallel and spaced apart, corresponding to the positions of the third PCB edge pad contacts 34.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper surface of the second printed circuit board 31 completely adheres to and covers the lower surface of the first printed circuit board 30, ensuring that the first and second printed circuit boards 30 and 31 remain parallel and stacked. The third and fourth PCB edge pad contacts 34 and 33 extend to the sides of the first and second printed circuit boards 30 and 31, respectively. Through side soldering, the corresponding third and fourth PCB edge pad contacts 34 and 33 are soldered to achieve bidirectional transmission of power and control signals between the first and second printed circuit boards 30 and 31. The first printed circuit board 30 is provided with the fourth PCB edge pad contact 33, which is used to output the electrical signals transmitted by the third PCB edge pad contact 34.

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 During operation, the first drive circuit 6 and the second drive circuit 32 work together to output multiple stable drive voltage signals. These signals are transmitted to the piezoelectric ceramic sheet 9 of the Jacquard guide needle block 10 through the side-welded conductive contact structure. The piezoelectric ceramic sheet 9 generates controllable bending deformation based on the piezoelectric inverse effect, driving the guide needle 40 to complete precise displacement and layered jacquard movements, achieving continuous and stable fabric weaving. The side solder joints are strong and have excellent vibration resistance, effectively avoiding problems such as poor signal contact and signal interruption during long-term operation of the equipment.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The first driving circuit 6 and the second driving circuit 32 are respectively arranged on different surfaces of the first printed circuit board 30 and the second printed circuit board 31, which effectively disperses the wiring pressure of the single-layer circuit board, avoids electromagnetic crosstalk caused by dense and intersecting lines, and ensures the stability of multi-channel driving signal transmission.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first printed circuit board 30 and the second printed circuit board 31 are connected by side soldering, which allows the first printed circuit board 30 and the second printed circuit board 31 to be completely bonded and stacked. There is no need to reserve solder pad space on the bonding surface, which greatly frees up the wiring space in the middle area of ​​the circuit board, improves the rationality of the circuit layout and the overall integration, and adapts to the needs of miniaturization and high density assembly.

[0041] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The fourth PCB edge pad contact 33 is arranged on the left and right edges of the lower surface of the second printed circuit board 31, and the two sets of fourth PCB edge pad contact 33 are arranged in parallel and spaced apart, so as to realize the independent conduction of the first driving circuit in 6 zones, further isolate the driving signals of different groups, reduce mutual interference of signals, and effectively improve the jacquard control accuracy.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The design employs a side-soldering connection structure, resulting in strong overall integrity and a secure connection after the solder joints are formed. Compared to traditional plug-in structures, it eliminates the risk of loosening or poor contact, and can withstand the high-speed vibration of warp knitting machines for extended periods, significantly improving equipment stability and service life. During disassembly, the solder joints are heated to melt the solder, thereby separating the first printed circuit board 30 and the second printed circuit board 31.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first printed circuit board 30 has a second socket 8 at the front, which can be directly connected to the piezoelectric ceramic sheet 9 of the Jacquard yarn guide needle block 10. The wiring and assembly operations are simple and convenient. Later equipment maintenance and parts replacement do not require disassembling the circuit board structure, effectively reducing maintenance difficulty and improving production and maintenance efficiency.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The first printed circuit board 30 and the second printed circuit board 31 are stacked in parallel, with a neat and compact overall structure that occupies little space. This facilitates the dense assembly of multiple jacquard combs on the comb base, adapting to the assembly requirements of high-needle-count and wide-width warp knitting equipment, and making the equipment highly versatile.

[0045] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0046] Example 4, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The difference between this embodiment four and embodiment one is that the two sets of third PCB board edge pad contacts 34 and the two sets of fourth PCB board edge pad contacts 33 are all arranged in an equidistant parallel interval, and the fourth PCB board edge pad contacts 33 are precisely arranged on the left and right sides of the lower surface of the second printed circuit board 31, providing sufficient operating space for side soldering.

[0047] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The side welding is performed using tin soldering, resulting in uniform and full weld filling and stable solder joint resistance. Simultaneously, the partitioned edge contact layout divides the drive circuit into two independent working areas. The two sets of circuit signals do not interfere with each other and can drive different groups of piezoelectric ceramic sheets 9, achieving multi-channel independent jacquard control. It can adapt to various specifications of guide needles 40, such as 16-needle and 32-needle, meeting the weaving needs of both simple and complex high-precision patterns, thus enhancing the equipment's versatility and adaptability.

[0048] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0049] Example 5, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The difference between this fifth embodiment and the first embodiment is that: the piezoelectric ceramic sheet 9 is disposed on the front part of the base 12 of the Jacquard yarn guide block 10, the yarn guide needle 40 is disposed on the front part of the piezoelectric ceramic sheet 9, a portion of the first printed circuit board 30 is disposed on the rear part of the base 12, and the output end of the first printed circuit board 30 is electrically connected to the input end of the piezoelectric ceramic sheet 9. A second conductive cable is disposed on the conductive sheet at the tail of the piezoelectric ceramic sheet 9, and a second plug 13 is disposed on the front end of the second conductive cable. The second plug 13 is installed into the corresponding second socket 8 by plugging. The base 12 is made of one of the following materials: aluminum alloy, aluminum-magnesium alloy, magnesium-aluminum alloy, or carbon fiber.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first printed circuit board 30 contains multiple conductive ribbon cables. A first driving circuit 6 is integrated within an IC chip 41, which is also integrated onto the first printed circuit board 30. The number of output pins of the IC chip 41 is X. A second socket 8 is located at the front end of the first printed circuit board 30, and the number of input pins of the second socket 8 is Y, where X = Y. Each output pin of the IC chip 41 is electrically connected to each input pin of the second socket 8 via a corresponding conductive ribbon cable. Each output pin is electrically connected to the corresponding piezoelectric ceramic sheet 9 via the corresponding output terminal of the first printed circuit board 30. X can be 32 or 64. The IC chip 41 contains a first driving circuit 6, and the number of first driving circuits 6 is Z, where Z = X.

[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first printed circuit board 30 has multiple independent, non-intersecting copper conductive lines formed inside by etching process. Each conductive line has metal pads at both ends for connecting the output pins of the IC chip 41 and the input pins of the second socket 8 respectively, so as to achieve one-to-one electrical connection.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The number of output pins of IC chip 41, the number of pins of second socket 8 and the number of actual yarn guide pins 40 are completely consistent, there are no idle or redundant pins, and all the driving resources of the chip can be fully utilized.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The piezoelectric ceramic sheet 9 is connected to the second plug 13 via the second conductive cable 3 at the tail conductive plate. The second plug 13 is plugged into the second socket 8. The pins of the second socket 8 transmit the high and low level drive signals output by the IC chip 41 to the piezoelectric ceramic sheet 9 through the plug and the wire. After receiving the high level voltage, the piezoelectric ceramic sheet 9 undergoes lateral deformation and drives the matching guide needle 40 to shift to complete the warp layer jacquard. When receiving the low level signal, there is no drive voltage input. The continuous dynamic switching of multiple signals, combined with the reciprocating motion of the comb, can complete the weaving of the complete fabric pattern.

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4Compared to the existing traditional Jacquard first printed circuit board 30, when producing 16 single-unit Jacquards, a 32-pin IC is used with a 32-pin second socket 8, and when producing 32 double-unit Jacquards, a 64-pin IC chip 41 is used with a 64-pin second socket 8. This avoids the problem of 32 pins being wasted when using a 64-pin chip to assemble 16 single-unit Jacquards. At the same time, a one-to-one wiring structure is adopted between the IC pins and the pins of the second socket 8. Each drive signal is equipped with an independent conductive ribbon cable for direct connection, eliminating the need for multi-level conversion solder joints. The number of pins is adjusted synchronously with the actual pin position, and the number of solder joints is reasonable.

[0055] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0056] Example 6, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The difference between this sixth embodiment and the first embodiment is that: an IC chip 41 is integrated and surface-mounted in the middle of the first printed circuit board 30, and the number of output pins X of the IC chip 41 is 64; a plastic insulated pluggable second socket 8 is welded and fixed to the front edge of the first printed circuit board 30, and the second socket 8 is arranged parallel to the front end of the board body, and the number of input pins Y of the second socket 8 is 64.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The 64 internal conductive ribbon cables connect the 64 IC output pins to the 64 second socket 8 input pins. All 64 output pins of the IC chip 41 are connected to the second socket 8 through conductive ribbon cables, corresponding to the 32 guide needles 40 piezoelectric ceramic plates 9. There are no idle pins, making full use of all the chip's driving resources.

[0058] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0059] Example 7, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The difference between this embodiment seven and embodiment one is that: the IC chip 41 is surface-mount integrated in the middle of the first printed circuit board 30. The IC chip 41 has Z independent first driving circuits 6 inside. The number of first driving circuits 6 Z is strictly matched with the number of IC output pins X. Each first driving circuit 6 receives a set of pattern level signals. The circuits are isolated from each other by the substrate insulation area. When the main control sends a high level signal, the internal switch of the corresponding first driving circuit 6 is turned on and outputs a stable driving voltage to the corresponding output pin. When the main control sends a low level signal, the internal switch of the corresponding first driving circuit 6 is turned off and no voltage is output. Multiple first driving circuits 6 can operate synchronously and independently, respectively controlling the piezoelectric ceramic sheet 9 matched with the single yarn guide needle 40.

[0060] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0061] Example 8, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The difference between this embodiment eight and embodiment one is that: the IC chip 41 integrates 64 independent first driving circuits 6, and the total number of first driving circuits 6 is Z=64, which satisfies the matching relationship Z=X.

[0062] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0063] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
