Description

Technical Field

[0001] This invention relates to the field of piezoelectric jacquard, and in particular to a wireless jacquard jacquard with multiple yarn guide needles. Background Technology

[0002] Piezoelectric jacquard is the core component of high-speed warp knitting machines to achieve multi-color jacquard weaving. It relies on the deformation of piezoelectric ceramic sheets when energized to drive the guide needles to deflect, thereby completing the layered jacquard action of the warp yarns. The drive circuit board is the signal control core of the piezoelectric ceramic sheet 4.

[0003] The existing Jacquard driver circuit board does not match the number of IC chip output pins with the number of socket input pins. If a 64-pin general-purpose IC chip is used to adapt to a 16-pin Jacquard comb, 32 chip output pins will be idle and wasted, resulting in low chip resource utilization and high circuit board hardware cost. Summary of the Invention

[0004] This invention provides a wireless jacquard jacquard with multiple yarn guide needles to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A wireless jacquard jacquard with multiple yarn guide needles includes a base, yarn guide needles, a piezoelectric ceramic sheet, a drive circuit board, an IC chip, and a socket. The piezoelectric ceramic sheet is disposed on the front part of the base. The yarn guide needle is located on the front part of the piezoelectric ceramic sheet. A portion of the drive circuit board is located on the rear of the base. The output terminal of the drive circuit board is electrically connected to the input terminal of the piezoelectric ceramic sheet. Multiple conductive ribbon cables are arranged within the drive circuit board. The IC chip is integrated on the driver circuit board, and the number of output pins of the IC chip is X. The socket is located on the front end of the driver circuit board, and the number of input pins of the socket is Y, where X=Y. The output pin of each IC chip is electrically connected to the input pin of each socket through a corresponding conductive cable, and each output pin is electrically connected to the corresponding piezoelectric ceramic sheet through the corresponding output terminal of the driver circuit board.

[0006] Furthermore, the IC chip is provided with a driving circuit, and the number of driving circuits is Z, where Z=X.

[0007] Furthermore, the driving circuit board is provided with a first conductive contact, through which an electrical signal is input to drive the driving circuit in the IC chip, wherein the electrical signal is a high level or a low level.

[0008] Furthermore, the drive circuit board is provided with a second conductive contact, which is used to output the electrical signal transmitted by the first conductive contact.

[0009] Furthermore, a second conductive cable 22 is provided on the conductive sheet at the tail of the piezoelectric ceramic sheet, and a plug is provided on the front end of the second conductive cable 22. The plug is installed into the corresponding socket in a plug-in manner.

[0010] Furthermore, when the value of X is 64, the value of Y is 64.

[0011] Furthermore, when the value of X is 32, the value of Y is also 32.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention has a simple structure and strong practicality. The number of output pins X of the IC chip is equal to the number of input pins Y of the first socket. It can match the corresponding pin specifications according to the Jacquard pin position, avoiding the pin idleness when adapting large-pin chips to products with few pins, and saving material costs.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

Terms such as “inner,” “outer,” “upper,” and “lower” are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0021] Example 1, refer to Figure 1 , Figure 2 and Figure 5 A wireless jacquard jacquard with multiple yarn guide needles is detachably mounted on the rear of the comb base via a connector, and can be directly plugged into and connected to the conductive plate at the tail of the piezoelectric ceramic plate 4 via a second conductive cable 22 and a second plug 35.

[0022] Reference Figure 1 and Figure 2 The wireless jacquard jacquard includes: a base 34, a yarn guide needle 5, a piezoelectric ceramic sheet 4, a drive circuit board 1, an IC chip 2, and a first socket 3. The piezoelectric ceramic sheet 4 is located on the front of the base 34, the yarn guide needle 5 is located on the front of the piezoelectric ceramic sheet 4, and a portion of the drive circuit board 1 is located on the rear of the base 34. The output terminal of the drive circuit board 1 is electrically connected to the input terminal of the piezoelectric ceramic sheet 4. A second conductive cable 22 is provided on the conductive sheet at the tail of the piezoelectric ceramic sheet 4, and a second plug 35 is provided at the front end of the second conductive cable 22. The second plug 35 is plugged into the corresponding first socket 3.

[0023] Reference Figure 1 and Figure 2 The driving circuit board 1 contains multiple conductive ribbon cables. An IC chip 2 is integrated onto the driving circuit board 1, and the number of output pins of the IC chip 2 is X. A first socket 3 is located at the front end of the driving circuit board 1, and the number of input pins of the first socket 3 is Y, where X = Y. Each output pin of the IC chip 2 is electrically connected to each input pin of the first socket 3 via a corresponding conductive ribbon cable. Each output pin is electrically connected to the corresponding piezoelectric ceramic sheet 4 through the corresponding output terminal of the driving circuit board 1. X can be 32 or 64. The IC chip 2 contains a driving circuit, and the number of driving circuits is Z, where Z = X.

[0024] Reference Figure 1 and Figure 2 The drive circuit board 1 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 pin of IC chip 2 and the input pin of first socket 15 respectively, to achieve one-to-one electrical connection. The drive circuit board 1 has mounting holes at the four corners, which can be fixed to the comb base as a whole with screws, making disassembly and assembly convenient.

[0025] The pattern control electrical signal is introduced into the IC chip 2 through the first conductive contact. The input electrical signal is divided into only two logic states: 5V high level and 0V low level. After the signal is processed by the IC chip, it triggers the corresponding drive circuit to conduct and output the drive voltage. The drive circuit board 1 is equipped with a second conductive contact. The second conductive contact is interconnected with the underlying circuit of the first conductive contact through the IC chip, which can synchronously split and transmit the input level and serve as an external detection port.

[0026] Reference Figure 1 and Figure 2 The piezoelectric ceramic sheet 4 is connected to the plug via a second conductive cable 22 at the tail conductive plate. The plug is installed in the first socket 3. The pins of the first socket 3 transmit the high and low level drive signals output by the IC chip 2 to the piezoelectric ceramic sheet 4 through the plug and the second conductive cable 22. When the piezoelectric ceramic sheet 4 receives a high level voltage, it undergoes lateral deformation and drives the matching guide needle 5 to shift to complete the warp layer jacquard. When it receives a low level signal, there is no drive voltage input, and the ceramic sheet resets itself due to its own elasticity. The guide needle 5 returns to its initial position. The continuous dynamic switching of multiple signals, combined with the reciprocating motion of the comb, can complete the weaving of the complete fabric pattern.

[0027] Reference Figure 1 and Figure 2 The overall structure can be matched with IC chip 2 and first socket 3 with the corresponding number of pins according to the 32-pin double jacquard specification. There is no hardware resource loss throughout the process. It is compatible with various warp knitting machine models with different widths and speeds, and has stronger versatility and adaptability for mass production.

[0028] Example 2, refer to Figure 1 and Figure 2 The difference between this second embodiment and the first embodiment is that: an IC chip 2 is integrally surface-mount soldered in the middle of the driver circuit board 1, and the number of output pins X on one side of the IC chip 2 is 64; a plastic insulated pluggable first socket 3 is soldered and fixed to the front edge of the driver circuit board 1, and the first socket 3 is arranged parallel to the front end of the board body, with the number of input pins Y of the first socket 3 being 64. Reference Figure 1 and Figure 2The 64 internal conductive ribbon cables connect the 64 IC output pins to the 64 input pins of the first socket 3 one by one. There are no shared pins or intermediate conductive contacts. All 64 output pins of the IC chip 2 are connected to the first socket 3 through conductive ribbon cables, corresponding to the 32 guide needles 5 and piezoelectric ceramic plates 4. There are no idle pins, making full use of all the chip's driving resources.

[0029] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0030] Example 3, referring to Figure 1 and Figure 2 The difference between this embodiment 3 and embodiment 1 is that the IC chip 2 is surface-mounted and integrated in the middle of the driving circuit board 1. The chip has Z independent driving circuits. The number of driving circuits Z and the number of IC output pins X are strictly matched. Each driving circuit receives a set of pattern level signals separately. The circuits are isolated from each other by the substrate insulation area. When the main controller sends a high-level signal, the corresponding internal switch of the driving circuit is turned on and outputs a stable driving voltage to the corresponding output pin. When the main controller sends a low-level signal, the corresponding internal switch of the driving circuit is turned off and no voltage is output. The multiple driving circuits can operate synchronously and independently, respectively controlling the piezoelectric ceramic sheet 4 matched with the single yarn guide needle 5.

[0031] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0032] Example 4, refer to Figure 1 and Figure 2 The difference between this fourth embodiment and the first embodiment is that the driving circuit board 1 is provided with a second conductive contact, which is used to output the electrical signal transmitted by the first conductive contact.

[0033] Reference Figure 1 and Figure 2 On the same side of the drive circuit board 1, below the first conductive contact, a second conductive contact is provided. The second conductive contact corresponds one-to-one with the first conductive contact. The second conductive contact is connected to the bottom copper foil circuit of the first conductive contact, and can shunt and output the input high and low level signals.

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

[0035] Example 5, refer to Figure 1 and Figure 2 The difference between this fifth embodiment and the first embodiment is that the driving circuit board 1 includes a first printed circuit board 10 and a second printed circuit board 11. The first printed circuit board 10 and the second printed circuit board 11 are stacked in parallel with each other, and the overall structure is flat and compact with high space utilization.

[0036] Reference Figure 1 and Figure 2 An IC chip 2 is integrated on the upper surface of the first printed circuit board 10. The IC chip 2 contains a first driving circuit, which outputs the driving signal required to drive the piezoelectric ceramic sheet 4. Two sets of third PCB edge pad contacts 12 are provided on the lower surface of the first printed circuit board 10. These two sets of third PCB edge pad contacts 12 are parallel to each other and spaced apart, forming two independent signal channels. A second driving circuit 14 is arranged on the lower surface of the second printed circuit board 11, cooperating with the first driving circuit to achieve multi-channel signal coordinated driving. A set of fourth PCB edge pad contacts 13 is provided on the left and right edges of the lower surface of the second printed circuit board 11. These two sets of fourth PCB edge pad contacts 13 are also arranged parallel to each other and spaced apart, corresponding to the positions of the third PCB edge pad contacts 12.

[0037] Reference Figure 1 and Figure 2 The upper surface of the second printed circuit board 11 completely adheres to and covers the lower surface of the first printed circuit board 10, ensuring that the first and second printed circuit boards 10 and 11 remain parallel and stacked. The third and fourth PCB edge pad contacts 12 and 13 extend to the sides of the first and second printed circuit boards 10 and 11, respectively. Through side soldering, the corresponding third and fourth PCB edge pad contacts 12 and 13 are soldered to establish conductivity, enabling bidirectional transmission of power and control signals between the first and second printed circuit boards 10 and 11. The first printed circuit board 10 is provided with the fourth PCB edge pad contact 13, which is used to output the electrical signals transmitted by the third PCB edge pad contact 12.

[0038] During operation, the first drive circuit and the second drive circuit 14 work together to output multiple stable drive voltage signals. These signals are transmitted to the piezoelectric ceramic sheet 4 of the Jacquard guide needle block 30 through the side-welded conductive contact structure. The piezoelectric ceramic sheet 4 generates controllable bending deformation based on the piezoelectric inverse effect, driving the guide needle 5 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 and Figure 2 The first driving circuit and the second driving circuit 14 are respectively arranged on different surfaces of the first printed circuit board 10 and the second printed circuit board 11, 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 and Figure 2 The first printed circuit board 10 and the second printed circuit board 11 are connected by side soldering, which allows the first printed circuit board 10 and the second printed circuit board 11 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 and Figure 2 The fourth PCB edge pad contact 13 is arranged on the left and right edges of the lower surface of the second printed circuit board 11, and the two sets of fourth PCB edge pad contact 13 are arranged in parallel and spaced apart, so as to realize the independent conduction of the drive circuit, further isolate the drive signals of different groups, reduce mutual interference of signals, and effectively improve the jacquard control accuracy.

[0042] Reference Figure 1 and Figure 2 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 adapt to the high-speed vibration operating conditions of warp knitting machines for extended periods, significantly improving equipment operational stability and service life. During disassembly, the solder joints are heated to melt the solder, thereby separating the first printed circuit board 10 and the second printed circuit board 11.

[0043] Reference Figure 1 and Figure 2 The first printed circuit board 10 has a first socket 3 at the front, which can be directly connected to the piezoelectric ceramic sheet 4 of the Jacquard yarn guide needle block 30. 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 and Figure 2 The first printed circuit board 10 and the second printed circuit board 11 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 6, refer to Figure 1 and Figure 2The difference between this sixth embodiment and the first embodiment is that the two sets of third PCB edge pad contacts 12 and the two sets of fourth PCB edge pad contacts 13 are all arranged in an equidistant parallel layout, and the fourth PCB edge pad contacts 13 are precisely arranged on the left and right sides of the lower surface of the second printed circuit board 11, providing sufficient operating space for side soldering.

[0047] Reference Figure 1 and Figure 2 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 4, achieving multi-channel independent jacquard control. It can adapt to the arrangement requirements of various specifications of guide needles 5, 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 7, refer to Figure 1 and Figure 2 The difference between this seventh embodiment and the first embodiment is that it also includes a second socket 20, a first conductive cable 21, and a second conductive cable 22.

[0050] Reference Figure 1 and Figure 2 The first printed circuit board 10 has a third PCB edge pad contact 12, a fourth PCB edge pad contact 13, and a first driving circuit on its upper part. The output of the first driving circuit is electrically connected to the third PCB edge pad contact 12. The second socket 20 is fixedly installed at the third PCB edge pad contact 12 and achieves stable conduction. The front end of the first conductive cable 21 integrates a first plug 23, which can be quickly connected to external devices. The rear end of the first conductive cable 21 is fixedly connected to the fourth PCB edge pad contact 13. During operation, the external first electrical signal is input to the driving circuit through the second socket 20 and the third PCB edge pad contact 12. The driving circuit outputs a matching second electrical signal according to the first electrical signal, and simultaneously outputs it outward through the fourth PCB edge pad contact 13 and the first conductive cable 21.

[0051] Reference Figure 1 and Figure 2The third PCB edge pad contact 12, the fourth PCB edge pad contact 13, the second socket 20, and the first conductive cable 21 are integrated on the upper part of the first printed circuit board 10. The first conductive cable 21, the first plug 23, and the second socket 20 constitute an integrated signal output channel and a signal input channel, replacing the traditional external distributed wiring structure. The wiring is neat and orderly, effectively solving the problem of messy and tangled cables in the whole machine.

[0052] Reference Figure 1 and Figure 2 The first electrical signal is input through the second socket 20 and the third PCB edge pad contact 12. After processing by the drive circuit, the second electrical signal is output through the fourth PCB edge pad contact 13, which can meet the needs of multiple piezoelectric Jacquard cascade assembly. The rear end of the first conductive cable 21 is fixedly connected to the fourth PCB edge pad contact 13 by welding. The connection is firm and has good vibration resistance, which can effectively avoid faults such as loosening of the line, breakage and signal abnormality during long-term operation.

[0053] Reference Figure 1 and Figure 2 A first socket 3 is provided at the lower part of the first printed circuit board 10. The piezoelectric ceramic sheet 4 is connected to the first socket 3 through the second plug 25 at the end of the second conductive cable 22, so as to achieve quick disassembly and assembly without cumbersome soldering operations, effectively improving the efficiency of equipment assembly, maintenance and replacement.

[0054] Reference Figure 1 and Figure 2 By setting a second conductive cable 22, a second socket 20, a first conductive cable 21, and a first plug 23, the signal input, signal cascade output, and piezoelectric ceramic driving functions are integrated onto a single first printed circuit board 10. The structure is compact, suitable for the narrow installation space inside the piezoelectric jacquard comb, 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.

[0055] Reference Figure 1 and Figure 2 The second socket 20 is welded and fixed to the edge pad 12 of the third PCB board as a whole, which is structurally robust, provides stable conductivity, and has both fixing and conductive functions. The second socket 20 and the first conductive cable 21 are arranged together in the exposed position on the upper part of the first printed circuit board 10 without structural obstruction, allowing for easy disassembly, assembly, and maintenance without interference.

[0056] Reference Figure 1 and Figure 2 The first socket 3 and the second plug 25 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.

[0057] Other structures are similar to those in Embodiment 1, and will not be described in detail here.

[0058] Example 9, referring to Figure 1 and Figure 2 The difference between Embodiment Nine and Embodiment One is that a tail clip 31 is provided on the rear part of the Jacquard guide needle block 30. The upper outer surface of the tail clip 31 is provided with a first slot 32 and a second slot 33 spaced apart. A portion of the first conductive cable 21 passes through the first slot 32 and extends outward from it. The opening of the second socket 20 is located within the second slot 33. The first slot 32 is convex in shape, and the second slot 33 is rectangular in shape.

[0059] Reference Figure 1 and Figure 2 The rear end of the first conductive cable 21 is fixed to the surface of the pad contact 13 on the edge of the fourth PCB board by soldering. The soldering structure has low contact resistance and stable conduction, which can resist the pulling effect caused by high frequency vibration of the equipment, avoid the line falling off and poor contact, and ensure long-term stable signal transmission.

[0060] Reference Figure 1 and Figure 2 A first socket 3 is fixedly mounted on the lower part of the first printed circuit board 10. The input end of the first socket 3 is electrically connected to the output end of the drive circuit, serving as a dedicated drive docking port for the piezoelectric ceramic sheet 4. A second conductive cable 22 is welded and fixed to the tail of the piezoelectric ceramic sheet 4. A second plug 25 is provided at the end of the second conductive cable 22. The second plug 25 can be directly plugged into the first socket 3, realizing a quick electrical connection between the drive circuit and the piezoelectric ceramic sheet 4, which is convenient for assembly and disassembly and has high efficiency.

[0061] Reference Figure 1 and Figure 2 The first external electrical signal is input into the drive circuit through the pad contact 12 on the edge of the third PCB board. After signal processing, the drive circuit outputs the second electrical signal. One signal is cascaded through the pad contact 13 on the edge of the fourth PCB board and the first conductive cable 21, while the other signal is output through the lower first socket 3, and then transmitted to the piezoelectric ceramic plate 4 via the second plug 25 and the second conductive cable 22. This drives the piezoelectric ceramic plate 4 to deform, thereby driving the yarn guide needle to complete the jacquard weaving action. The second socket 20 and the first conductive cable 21 are located in the exposed area on the upper part of the first printed circuit board 10, without structural obstruction, making disassembly and maintenance convenient. The second socket 20 is welded and fixed to the pad contact 12 on the edge of the third PCB board, resulting in a stable overall structure. The first socket 3 and the second plug 25 are tightly connected, effectively resisting equipment vibration and preventing the interface from loosening.

[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.
