Description

Technical Field

[0001] This invention relates to the field of warp knitting machines, and in particular to a jacquard driver and a wireless jacquard device. Background Technology

[0002] A piezoelectric Jacquard consists of a piezoelectric needle selector, needle clip, yarn guide needle, protective cover, cable plug, and an aluminum-magnesium alloy base for fixing and limiting the piezoelectric needle selector. The corresponding machine size is indicated by the number of needles per inch. It is a cantilever beam structure in which two piezoelectric ceramic plates are symmetrically bonded to an elastic substrate. The commonly used DC drive voltage is 200V, and the average drive current per plate is less than 1mA. Under the excitation of an external rectangular pulse signal, a 200V DC drive voltage is alternately applied to the two ceramic plates of the piezoelectric needle selector. Due to the inverse piezoelectric effect, the piezoelectric ceramic plates continuously contract, bend, or recover during charging and discharging, driving the Jacquard yarn guide needle to perform a periodic deflection motion.

[0003] The piezoelectric needle guide consists of a three-layer structure: piezoelectric ceramic, substrate (insulating glass fiber layer), and piezoelectric ceramic again. Utilizing the "inverse piezoelectric effect," when a positive external electric field is applied in the same direction as the polarization, the polarization intensity is enhanced, causing the piezoelectric ceramic to elongate along the polarization direction. Conversely, when a reverse external electric field is applied in the opposite direction, the polarization intensity is weakened, causing the piezoelectric ceramic to shorten along the polarization direction. Alternating positive and negative voltages are applied to both sides of the piezoelectric Jacquard element by a drive controller, causing the piezoelectric ceramic to bend, thus allowing the guide needle to deflect to the left or right. By setting positioning blocks on both sides of the Jacquard guide needle, its deflection angle can be precisely controlled. Furthermore, because the piezoelectric ceramic has a capacitor-like effect, the piezoelectric Jacquard element can maintain its offset position.

[0004] Chinese invention patent (application number: 201710030965.9, publication number: CN106757749B) discloses an active jacquard drive system, comprising: at least one driver mounted on a jacquard for directly driving the jacquard needles on the jacquard, the driver having a first interface; at least one CPU for receiving process signals and processing the process signals to output CLK clock signals, LE signals and data signals to the driver; a ribbon cable including circuitry for providing the required drive power to the CPU and the driver, process signal lines, and the ribbon cable also connected to at least one second interface for providing drive power and CLK clock signals, LE signals and data signals. This prior art lacks a debugging port, requiring all jacquard devices to be powered on each time, and cannot achieve the goal of powering on only a single designated wireless jacquard device, which refers to the wireless jacquard device that needs to be debugged before the warp knitting machine is run.

[0005] Currently, in existing wireless jacquard knitting devices, two parallel copper strips are arranged on the carding bed, one as the positive electrode and the other as the negative electrode. One end of each copper strip is electrically connected to a power source. The conductive pins inside the wireless jacquard knitting device contact the copper strips to draw power. Existing wireless jacquard knitting devices use copper strips instead of cables for power supply, thus achieving wireless operation. This wireless operation means that there is no cable at the tail end during operation, solving the problem of the cable at the tail end of the wired piezoelectric jacquard affecting normal operation in traditional warp knitting machines (see Appendix CN106757749B for details). Figure 2 It is a wired piezoelectric jacquard.

[0006] However, existing wireless jacquard knitting devices still have the following shortcomings in practical use: 1. The aforementioned power supply method requires the length of the copper strip to be equal to the length of the carding bed, thus requiring two very long copper strips. 2. Because the copper strips are exposed to the air for a long time during use, the stability of the copper strips' conductivity is reduced over time, affecting the normal operation of the wireless jacquard knitting device. Summary of the Invention

[0007] This invention provides a Jacquard driver and a wireless Jacquard device. Its main purpose is to overcome the shortcomings of the Jacquard driver in the wireless Jacquard device, which uses a pin to contact a copper strip for power supply. This power supply method has the defect of insufficient power supply stability during long-term use.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A Jacquard driver includes at least one printed circuit board, multiple drive circuits disposed on the printed circuit board, at least one first power port and at least one second power port, and a first ribbon cable disposed within the printed circuit board. The first ribbon cable includes circuitry for providing the required drive power to the drive circuitry and process signal lines. The first ribbon cable is used to connect the first power port and the second power port. The output terminal of the first power port and the input terminal of the second power port are respectively soldered onto the printed circuit board, such that the first power port, the second power port, and the printed circuit board are electrically connected together to form an inseparable whole.

[0010] A wireless Jacquard jacquard device includes an actuator, a base, and a Jacquard driver. The actuator has a plurality of piezoelectric Jacquard elements arranged on the base. A portion of the Jacquard driver is detachably mounted on a portion of the base. The Jacquard driver is used to drive the piezoelectric Jacquard elements to oscillate and guide the jacquard yarn. The output end of the Jacquard driver is detachably mounted on the enable end of the piezoelectric Jacquard elements. The Jacquard driver is the Jacquard driver described above.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] This invention features a simple structure and strong practicality. By setting the output end of the first power-on port and the input end of the second power-on port, which are respectively soldered onto a printed circuit board, the first power-on port, the second power-on port, and the printed circuit board are electrically connected together to form an inseparable whole. This whole serves as a power-gathering unit, providing wireless power. On the one hand, it replaces the existing copper strip and pin power-gathering method, improving the integration of the power-gathering unit and the stability of the power supply. On the other hand, by setting up the circuit board, a portion of the printed circuit board can be detachably mounted on a portion of the base, facilitating the separation and replacement of the Jacquard driver during later maintenance. When the piezoelectric Jacquard element is damaged, the detached, usable Jacquard driver can be transferred and installed on another base for reuse, thereby reducing product costs and achieving a dual benefit.

[0013] In this invention, by placing the driving circuit on a printed circuit board, the driving circuit is integrated with the first power connection port and the second power connection port on the same printed circuit board, forming an inseparable whole. On the one hand, this allows the Jacquard driver to not only have the function of wireless power supply, but also integrate the driving circuit, thereby improving the integration of the Jacquard driver, making reasonable use of the space of the printed circuit board and reducing waste. On the other hand, it eliminates other adapter parts and has the advantage of improving response speed, achieving two benefits at once.

[0014] In this invention, by setting a plug-in element, the Jacquard driver can be plugged into and detachably installed on the power terminal of the piezoelectric Jacquard element. This allows the entire Jacquard driver to be quickly plugged into and detached from the piezoelectric Jacquard element. On the one hand, when installing the Jacquard driver, the plugging and detaching method allows for quick installation between the output end of the Jacquard driver and the power terminal of the piezoelectric Jacquard element, establishing an electrical connection. When disassembling the Jacquard driver, the plugging and detaching method allows for quick separation between the Jacquard driver and the power terminal of the piezoelectric Jacquard element, facilitating subsequent maintenance. On the other hand, by directly connecting the output end of the Jacquard driver to the power terminal of the piezoelectric Jacquard element via a plugging method, the intermediate adapter is eliminated, allowing the Jacquard driver to directly drive the piezoelectric Jacquard element to perform jacquard yarn guiding action, improving response speed and achieving a dual benefit.

[0015] In this invention, by electrically connecting the input end of the plug-in element to the printed circuit board, an inseparable whole is formed. Thus, during separation, it is only necessary to pull the plug-in element out of the power terminal of the piezoelectric Jacquard element to separate the first power terminal, the second power terminal, the drive circuit, and the printed circuit board together, which is quick and convenient. During installation, it is only necessary to insert the plug-in element into the power terminal of the piezoelectric Jacquard element to achieve electrical connection between the drive circuit and the power terminal of the piezoelectric Jacquard element, and at the same time complete the installation and positioning of the printed circuit board, the first power terminal, and the second power terminal. It is simple and convenient, achieving two goals at once.

[0016] In this invention, the output of the third power port 120 is soldered onto the printed circuit board, so that the output of the third power port 120 is electrically connected to the printed circuit board, forming an inseparable whole. On the one hand, this makes reasonable use of the space at the rear of the printed circuit board, and on the other hand, it integrates the third power port 120 with the first power port and the second power port onto the same printed circuit board, forming an inseparable whole. This allows the Jacquard driver to not only have wireless power supply function, but also integrate adjustment function when adjusting the pin pitch, improving the integration of the Jacquard driver, making reasonable use of the space of the printed circuit board, reducing waste, and eliminating other adapter parts, which has the advantage of improving response speed, achieving two benefits at once.

[0027] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] Example 1, refer to Figure 1 A Jacquard driver and a wireless Jacquard device are disclosed. The wireless Jacquard device can be installed in a warp knitting machine. The wireless Jacquard device has an actuator, a base 111, and a Jacquard driver 112. The Jacquard driver 112 is used to drive the piezoelectric Jacquard element 102 to work and realize jacquard yarn guiding. The output end of the Jacquard driver 112 is detachably installed on the enable end of the piezoelectric Jacquard element 102.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The Jacquard driver 112 includes at least one printed circuit board 113, at least one first power port 114, at least one second power port 115, a first ribbon cable 116 disposed within the printed circuit board 113, at least one third power port 120 disposed at the tail of the printed circuit board 113, at least one plug-in element 300, multiple drive circuits 118 controlled by an external controller, a second ribbon cable 117 disposed within the printed circuit board 113, and a third ribbon cable 119 disposed within the printed circuit board 113. The drive circuits 118 are disposed on the printed circuit board 113, and the specific drive circuits 118 are used to drive the corresponding piezoelectric ceramic sheet to work.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The first power port 114 is soldered to the left side of the printed circuit board 113, the second power port 115 is soldered to the right side of the printed circuit board 113, the plug-in element 300 is soldered to the front of the printed circuit board 113, and the third power port 120 is soldered to the rear of the printed circuit board 113. The first power port 114, the second power port 115, the plug-in element 300, the third power port 120, and the printed circuit board 113 are electrically connected together by soldering to form an inseparable whole 600.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first ribbon cable 116 includes a circuit that provides the required driving power to the driving circuit 118 and a process signal line. The first ribbon cable 116 is used to connect the first power connection port 114 and the second power connection port 115.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The output terminal of the first power connection port 114 and the input terminal of the second power connection port 115 are respectively soldered onto the printed circuit board 113, so that the first power connection port 114, the second power connection port 115 and the printed circuit board 113 are electrically connected together to form an inseparable whole. A part of the printed circuit board 113 is detachably mounted on a part of the base 111, and the piezoelectric Jacquard element 102 is detachably mounted on another part of the base 111. Alternatively, the piezoelectric Jacquard element 102 can also be detachably mounted on another part of the base 111. In this embodiment, the piezoelectric Jacquard element 102 can be located on the front of the base 111, and the printed circuit board 113 can be detachably located on the rear of the base 111. The base 111 is made of aluminum-magnesium alloy, aluminum alloy or magnesium alloy.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4By setting the output end of the first power connection port 114 and the input end of the second power connection port 115, which are respectively soldered onto the printed circuit board 113, the first power connection port 114, the second power connection port 115 and the printed circuit board 113 are electrically connected together to form an inseparable whole. This whole serves as a power-gathering unit and performs the function of wireless power supply. On the one hand, it replaces the existing copper strip and pin power supply method, improving the integration of the power-gathering unit and the stability of power supply. On the other hand, by setting it up, a part of the printed circuit board 113 can be detachably mounted on a part of the base 111, which facilitates the separation and replacement of the Jacquard driver 112 during later maintenance. When the piezoelectric Jacquard element 102 is damaged, the detached and usable Jacquard driver 112 can be transferred and installed on other bases 111 for reuse, thereby reducing product costs and achieving two benefits at once.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The second ribbon cable 117 is used to connect the first power connection port 114 and the drive circuit 118. The second ribbon cable 117 includes a circuit that provides the required drive power to the drive circuit 118 and a process signal line.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The third cable 119 is used to connect the third power port 120 to the drive circuit 118. The third cable 119 includes a circuit that provides the required drive power to the drive circuit 118 and a process signal line. When the needle pitch is adjusted, the third power port 120 is powered on. When the warp knitting machine is running normally, that is, when the wireless jacquard device is normally jacquard guiding the yarn, the third power port 120 is not powered on.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 By setting a third power port 120 and a third ribbon cable 119 located in the printed circuit board 113, when the stitch length needs to be adjusted before the warp knitting machine is running, a single wireless jacquard device can be started as needed. An external cable connected separately to an external controller is used. This external cable is plugged into the third power port 120 in a pluggable manner to provide power, thereby driving the single wireless jacquard device that needs to be adjusted independently. After the adjustment is completed, the external cable can be directly unplugged to end the adjustment. This allows for quick and convenient adjustment of the stitch length of a specified single wireless jacquard device.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The printed circuit board 113 includes a first printed circuit board body 321 and a second printed circuit board body 322. The output terminal of the first printed circuit board body 321 and the input terminal of the second printed circuit board body 322 are electrically connected together by soldering to form an inseparable whole.

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The output terminal of the first power connection port 114, the input terminal of the second power connection port 115, and the output terminal of the third power connection port 120 are all soldered onto the first printed circuit board body 321 and electrically connected together to form an inseparable whole. The output terminal of the second printed circuit board body 322 and the output terminal of the plug-in element 300 are soldered together to form an inseparable whole.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The actuator has multiple piezoelectric Jacquard elements 102 arranged on the base 111. Each piezoelectric Jacquard element 102 includes at least one Jacquard pin 130, at least one substrate 502, two piezoelectric ceramic sheets 500 respectively wrapped around the left and right sides of the substrate 502, and two copper foil terminals 501 respectively disposed on the left and right sides of the substrate 502. The two copper foil terminals 501 are electrically connected to the tail of the corresponding piezoelectric ceramic sheet 500. The front of the substrate 502 is connected to the Jacquard pin 130. The voltage output by the drive circuit 118 is applied to the piezoelectric ceramic sheet 500 to drive the piezoelectric element 130. The piezoelectric ceramic sheet 500 oscillates, and the substrate 502 is an insulating layer, specifically a glass fiber sheet. The front end of the piezoelectric ceramic sheet 500 is provided with Jacquard needles 130. The substrate 502 and two piezoelectric ceramic sheets 500 are combined to form a piezoelectric needle selection plate. Typically, 16 Jacquard needles 130 can be set on a base 111, arranged horizontally. The specific number of Jacquard needles 130 is determined according to the machine number of the warp knitting machine. The piezoelectric ceramic sheet 500 is energized by the Jacquard driver 112 to perform polarization treatment, so that they become opposite poles, causing the two piezoelectric ceramic sheets 500 to actively bend in the same direction at the same time.

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5When in use, the base 111 of one wireless jacquard device (wireless jacquard device 104) is placed close to the base 111 of another wireless jacquard device (wireless jacquard device 103), and the second power port 115 of one wireless jacquard device (wireless jacquard device 104) is placed close to the first power port 114 of another wireless jacquard device (wireless jacquard device 103). This allows the second power port 115 of one wireless jacquard device (wireless jacquard device 104) and the first power port 114 of another wireless jacquard device (wireless jacquard device 103) to be detachably installed together by plugging in, thereby quickly achieving electrical connection. This has the advantage of convenient installation, meets the needs of rapid installation, and achieves two benefits at once.

[0041] Although, Figure 5 The diagram only shows four wireless jacquard devices, but in actual use, it should not be limited to installing four wireless jacquard devices at the same time. The wireless jacquard device is used on warp knitting machines, and multiple wireless jacquard devices need to be set in the warp knitting machine. The specific number depends on the model number of the warp knitting machine.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The first power connector 114 is either a male or female power connector, and the second power connector is either a female or male power connector. When the first power connector 114 is a male power connector, the second power connector 115 is a female power connector, and when the first power connector 114 is a female power connector, the second power connector 115 is a male power connector.

[0043] Reference Figure 2 , Figure 3 and Figure 5 When disassembly is required, the wireless jacquard device to be disassembled can be directly removed from the carding machine 101. Power is cut off the moment the wireless jacquard device is removed. The power-off process is explained below:

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The second power port 115 of one wireless jacquard device (wireless jacquard device 104) and the first power port 114 of another wireless jacquard device (wireless jacquard device 103) can also be electrically connected by plugging, magnetic attraction or pressing.

[0045] The electrical connection between the male and female electrical connectors can be achieved through pressure spring contact, pin contact, or ball contact.

[0046] When the male connector is a conductive pressure spring, the female connector is a conductive plug slot, and the electrical connection is achieved through pressure spring contact.

[0047] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 During installation, the base 111 of one wireless jacquard device (wireless jacquard device 104) is close to the base 111 of another wireless jacquard device (wireless jacquard device 103), and the second power port 115 of one wireless jacquard device (wireless jacquard device 104) is close to the first power port 114 of another wireless jacquard device (wireless jacquard device 103). Because the pressure spring of the male power port is elastic, it can be directly inserted into the insertion slot of the female power port in a plug-in manner, so that the pressure spring directly abuts against the insertion slot to achieve electrical connection. Then, the base 111 is locked to the combing bed 101 using the tail clip 122.

[0048] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 When disassembling, after loosening the locking screw on the tail clip 122, the wireless jacquard device (wireless jacquard device 104) can be directly removed from the combing machine 101. Because the pressure spring of the male connector is elastic, the pressure spring can be separated from the insertion slot by pulling it out during the removal of the wireless jacquard device, thereby achieving power disconnection.

[0049] When the male connector has a conductive pin, the female connector has a conductive groove, and the pin can be a conductive spring pin. The electrical connection is achieved through a pin-type contact.

[0050] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5During installation, the base 111 of one wireless jacquard device (wireless jacquard device 104) is placed close to the base 111 of another wireless jacquard device (wireless jacquard device 103), and the second power port 115 of one wireless jacquard device (wireless jacquard device 104) is placed close to the first power port 114 of another wireless jacquard device (wireless jacquard device 103). Because the pin of the male power port can be directly inserted into the pin groove of the female power port in a plug-in manner, an electrical connection is achieved. Then, the base 111 is locked onto the combing bed 101 using the tail clip 122.

[0051] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 When disassembling, loosening the locking screw on the tail clip 122 allows the ejector pin to be pulled out of the needle groove during the removal of the wireless jacquard device, thus separating the ejector pin from the needle groove and disconnecting the power.

[0052] When the male connector has a conductive round ball, the female connector has a conductive ball groove, and the electrical connection is achieved through a round ball contact.

[0053] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 During installation, the base 111 of one wireless jacquard device (wireless jacquard device 104) is placed close to the base 111 of another wireless jacquard device (wireless jacquard device 103), and the second power port 115 of one wireless jacquard device (wireless jacquard device 104) is placed close to the first power port 114 of another wireless jacquard device (wireless jacquard device 103). Because the male power port is a round ball, it can be directly inserted into the ball groove of the female power port by plugging it in, so that the round ball directly abuts against the ball groove to achieve electrical connection. Then, the base 111 is locked to the combing bed 101 using the tail clip 122.

[0054] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5When disassembling, after loosening the locking screw on the tail clip 122, the wireless jacquard device (wireless jacquard device 104) can be directly removed from the combing machine 101. During the removal of the wireless jacquard device, the round ball of the male power connector will roll out of the ball groove by pulling it out, thereby separating the round ball from the ball groove and thus cutting off the power.

[0055] When the male connector is a conductive magnetic connector, the female connector is a conductive magnetic connection slot, and the electrical connection is achieved through magnetic contact.

[0056] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 During installation, the base 111 of one wireless jacquard device (wireless jacquard device 104) is placed close to the base 111 of another wireless jacquard device (wireless jacquard device 103), and the second power port 115 of one wireless jacquard device (wireless jacquard device 104) is placed close to the first power port 114 of another wireless jacquard device (wireless jacquard device 103). Because the magnetic connector of the male power port is magnetic, it can be directly connected to the magnetic connection slot in a magnetic manner to achieve phase connection. Then, the base 111 is locked to the combing bed 101 using the tail clip 122.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 When disassembling, after loosening the locking screw on the tail clip 122, the wireless jacquard device (wireless jacquard device 104) can be directly removed from the combing bed 101. In the process of removing the wireless jacquard device, the magnetic connector can be separated from the magnetic connection slot by pulling it out, thereby achieving power disconnection.

[0058] For specific details regarding the external controller in this embodiment, please refer to the references provided in the background section (Chinese Invention Patent Application No.: 201710030965.9, Publication No.: CN106757749B). The CPU described therein is an external controller in the prior art, and the references provide detailed descriptions and explanations, which will not be repeated here.

[0059] Reference Figure 1 and Figure 7A plurality of first mounting holes 202 are provided on the rear part of the base 111, and a plurality of second mounting holes 201 are provided on the printed circuit board 113. The first mounting holes 202 and the second mounting holes 201 are adapted to each other. After the screw 200 passes through the second mounting hole, it is locked in the first mounting hole 202, so that the printed circuit board 113 can be detachably mounted on the rear part of the base 111.

[0060] Reference Figure 1 When the stitch length needs to be adjusted before the warp knitting machine is running, a single wireless jacquard device can be started as needed. Specifically, an external cable that is separately connected to an external controller is used. This external cable is plugged into the third power port 120 in a pluggable manner to provide power (input drive power and process signals), thereby driving the single wireless jacquard device that needs to be adjusted. After the adjustment is completed, the external cable is simply unplugged to end the adjustment. This allows for quick and convenient adjustment of the stitch length of a specified single wireless jacquard device.

[0061] The stitch length of a warp knitting machine typically refers to the left-right position of the guide bar relative to the knitting needles. The left-right distance of the entire row of guide needles relative to the knitting needles is controlled by the slider top wire of the pattern wheel. Using the knitting needles as a reference, observe the left-right position of the guide bar and adjust the direction of the top wire to move the guide bar slightly laterally, to the middle of the knitting needles. The stitch length needs to be adjusted before the warp knitting machine can operate normally.

[0062] Reference Figure 1 , Figure 2 , Figure 3 When the warp knitting machine is being tested before use with the wireless jacquard device, the third power port 120 is powered on, while the first power port 114 and the second power port 115 are not powered on. The third power port 120 is powered on only when the stitch length is being tested by connecting an external cable. The tail clip 122 has a wire groove 121, through which the external cable can be inserted to connect to the third power interface. When the warp knitting machine is working normally, the third power port 120 is idle, with no external cable installed and no power supply.

[0063] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 When the warp knitting machine is running normally, the first power port 114, the drive circuit 118, the second power port 115, and the plug-in element 300 are all powered (input drive power and process signals), while the third power port 120 is not powered.

[0064] Example 2, refer to Figure 2The difference between this second embodiment and the first embodiment is that the driving circuit 118 is used to drive the corresponding piezoelectric ceramic sheet to work, so that the Jacquard needle 130 of the piezoelectric Jacquard element 102 swings to realize the jacquard yarn guiding action. By setting the driving circuit 118 on the printed circuit board 113, the driving circuit 118 is integrated with the first power connection port 114 and the second power connection port 115 on the same printed circuit board 113 to form an inseparable whole. On the one hand, the Jacquard driver 112 not only has the function of wireless power supply, but also integrates the driving circuit 118, which improves the integration of the Jacquard driver 112, makes reasonable use of the space of the printed circuit board 113 and reduces waste. On the other hand, it eliminates other adapter parts and has the advantage of improving response speed, achieving two benefits at once.

[0065] Example 3, refer to Figure 4 and Figure 6 The difference between this embodiment 3 and embodiment 2 is that the driving circuit 118 includes power supply DC1, power supply DC2, resistor R1, resistor R2, resistor R3, capacitor C1, capacitor C2, diode D1, diode D2, diode D3, diode D4, diode D5, transistor Q1, transistor Q2, 5V power supply and control signal input terminal INPUT.

[0066] Reference Figure 6 One end of resistor R3 is electrically connected to the 5V power supply, and the other end of resistor R3 is electrically connected to the base of transistor Q2. The control signal input terminal INPUT is electrically connected to the emitter of transistor Q2. The collector of transistor Q2, the cathode of diode D5, the base of transistor Q1, and one end of resistor R1 are connected together. The base of transistor Q1, the other end of resistor R1, and one end of power supply DC1 are connected together. The emitter of transistor Q1, the anode of diode D5, and one end of resistor R2 are connected together. One end of capacitor C2, the other end of resistor R2, and the cathode of diode D4 are connected together. The anode of diode D4 is electrically connected to the anode of diode D3. The cathodes of diode D2 and D3, one end of capacitor C1, and the other end of capacitor C2 are connected together. The anode of diode D2 is electrically connected to the anode of diode D1. The cathode of diode D1, the other end of capacitor C1, the other end of power supply DC1, and one end of power supply DC2 are connected together. The other end of power supply DC2 is grounded.

[0067] Reference Figure 6By setting diodes D1, D2, D3, and D4 together to form a capacitor charging and discharging circuit, on the one hand, the common point between capacitors C1 and C2 does not need to be grounded; on the other hand, the lifespan of the piezoelectric ceramic sheet 500 is linearly related to the forward voltage. When the piezoelectric ceramic sheet 500 is subjected to the same voltage, when the charging direction is from C2 to C1, D1 and D2 share a portion of the voltage to C1, causing the voltage across C2 to decrease accordingly, but the magnitude remains unchanged. When the charging direction is from C1 to C2, D1 and D2 share a portion of the voltage to C2, causing the voltage across C1 to decrease accordingly, but the magnitude remains unchanged. The final result is that, under the premise of constant magnitude, the forward voltage across the piezoelectric ceramic sheet 500 is reduced, thus extending the lifespan of the piezoelectric ceramic sheet 500.

[0068] Reference Figure 1 , Figure 5 and Figure 6 The drive circuit 118 has the characteristics of having a small number of components and being easy to integrate, and it also has the function of driving the piezoelectric ceramic sheet 500 with positive and negative voltage.

[0069] Reference Figure 6 Diode D2 is a Zener diode, and diode D3 is a Zener diode.

[0070] Reference Figure 6 Capacitors C1 and C2 are the equivalent capacitances of the two piezoelectric ceramic plates 500. At any given time, only one of capacitors C1 and C2 is in a charging state, while the other is in a discharging state, causing the piezoelectric ceramic plate 500 to swing left and right.

[0071] Reference Figure 6 Power supply DC1 is a high-voltage DC power supply, and power supply DC2 is a high-voltage DC power supply.

[0072] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7 The working principle of drive circuit 118:

[0073] Reference Figure 71. The input signal at the INPUT terminal is input through the emitter (E) of Q2, and this signal is a 5V TTL signal. When the control signal at the INPUT terminal is high, since the base (B) of Q2 is connected to a 5V power supply through R3, the voltage difference between the emitter (E) and base (B) of Q2 is 0, so Q2 is in the off state. The DC power supply DC1 provides current to the base (B) of Q1 through R1. After being amplified by Q1, the current flows out from the emitter (E) of Q2, and then charges the 500 piezoelectric ceramic plate through R2. Resistor R2 here is a current-limiting resistor, which limits the charging current. Since Q2 is in the off state, DC2 has no effect at this time. Finally, the voltage direction in the diagram is high at point B and low at point C, and the charging direction is from B to C.

[0074] Reference Figure 7 2. When the input control signal at the INPUT terminal is low, +5V flows through R3 to the base of Q2, making Q2 conduct. After Q2 conducts, its collector (C terminal) is approximately zero, ignoring the Q2Vce voltage drop. Therefore, under the clamping effect of D5, Q1 quickly enters the cutoff state. At this time, DC1 has no effect, and DC2 enters from point C, passing through R2, and Q2 charges the circuit in reverse. Ultimately, the voltage direction in the diagram is high at point C and low at point B, with the charging direction from C to B.

[0075] Reference Figure 7 Taking point B as the high voltage and point C as the low voltage, meaning the charging direction is from B to C, D4 is reverse-biased and has no effect. The charging voltage is supplied to C2 and C1. Since D2 is a Zener diode, when the voltage Vac of C1 is greater than the Zener voltage of D2, D2 will conduct, making the voltage Vac of C1 equal to the Zener voltage of D2. Typically, the Zener voltage of D2 is around 10-30V, so C2 will experience normal high-voltage charging, while C1 will experience negative low-voltage charging. The sum of these two voltages equals the DC1 voltage. The reason and benefit of this approach are as follows: The lifespan of the piezoelectric ceramic plate 500 is linearly related to the forward voltage; the higher the voltage, the greater the oscillation force but the shorter the lifespan. However, by adding D1 to D4, when the piezoelectric ceramic plate 500 is subjected to the same voltage, D1 and D2 share a portion of the voltage with C1, causing the voltage across C2 to decrease accordingly, while the oscillation force remains unchanged. The final result is that, without changing the oscillation force, the forward voltage across the piezoelectric ceramic plate 500 is reduced, thus extending its lifespan. Similarly, when C is high and B is low, the reasoning is the same. In this case, C1 releases negative voltage and, in turn, bears the positive high voltage, while C2 discharges through Q2 and shares a portion of the negative voltage, a process similar to the above.

[0076] Reference Figure 1 and Figure 2In addition to the driving circuit of this embodiment, the driving circuit 118 can also be replaced with other driving circuits for driving the piezoelectric ceramic sheet. For example, see reference (Chinese Utility Model Patent Application No.: CN202121926084.3, Publication No.: CN217486404U), or reference (Chinese Invention Patent Application No.: CN202011631491.1, Publication No.: CN114696655A), or reference (Chinese Utility Model Patent Application No.: CN202122770158.5, Publication No.: CN216585483U), or reference (Chinese Utility Model Patent Application No.: CN202120303871.6, Publication No.: CN217486404U), or reference (Chinese Utility Model Patent Application No.: CN202120303871.6, Publication No.: CN217486404U).

That is to say, the driving circuit used to drive the piezoelectric ceramic sheet in the art can replace the driving circuit provided in this embodiment. Other driving circuits in the art can be set on the printed circuit board 113 to drive the piezoelectric ceramic sheet of the wireless jacquard device.

[0077] Other structures are similar to those in Embodiment 2, and will not be described in detail here.

[0078] Example 4, refer to Figure 2 and Figure 3 The difference between this fourth embodiment and the first embodiment is that the first power port 114 is located on the left side of the printed circuit board 113, the second power port 115 is located on the right side of the printed circuit board 113, and the plug-in element 300 is located on the front of the printed circuit board 113.

[0079] Reference Figure 1 , Figure 2 and Figure 3 The input terminal of the plug-in element 300 is soldered onto the printed circuit board 113, so that the input terminal of the plug-in element 300 is electrically connected to the printed circuit board 113 to form an inseparable whole. The plug-in element 300 can be plugged into and detachably installed on the power terminal of the piezoelectric Jacquard element 102.

[0080] Reference Figure 1 , Figure 2 and Figure 3By setting the plug-in element 300, the plug-in element 300 can be plugged into and detachably installed on the power terminal of the piezoelectric Jacquard element 102. This allows the entire Jacquard driver 112 to be quickly plugged into and detached from the piezoelectric Jacquard element 102. On the one hand, when installing the Jacquard driver 112, the plugging and detaching method allows for quick installation and electrical connection between the output terminal of the Jacquard driver 112 and the power terminal of the piezoelectric Jacquard element 102. On the other hand, by directly connecting the output terminal of the Jacquard driver 112 to the power terminal of the piezoelectric Jacquard element 102 via plugging, the intermediate adapter is eliminated. This allows the Jacquard driver 112 to directly drive the piezoelectric Jacquard element 102 to perform jacquard yarn guiding action, improving response speed and achieving two benefits at once.

[0081] Reference Figure 1 , Figure 2 and Figure 3 By electrically connecting the input terminal of the plug-in element 300 to the printed circuit board 113, an inseparable whole is formed. During separation, simply unplugging the plug-in element 300 from the power terminal of the piezoelectric Jacquard element 102 allows for the separation of the first power terminal 114, the second power terminal 115, the drive circuit 118, and the printed circuit board 113 together, which is quick and convenient. During installation, simply inserting the plug-in element 300 into the power terminal of the piezoelectric Jacquard element 102 establishes an electrical connection between the drive circuit 118 and the power terminal of the piezoelectric Jacquard element 102, while simultaneously completing the installation and positioning of the printed circuit board 113, the first power terminal 114, and the second power terminal 115. This simple and convenient approach achieves two goals at once.

[0084] Reference Figure 1 , Figure 2 and Figure 3By soldering the output of the third power port 120 onto the printed circuit board 113, the output of the third power port 120 is electrically connected to the printed circuit board 113, forming an inseparable whole. This makes good use of the space at the rear of the printed circuit board 113, and integrates the third power port 120 with the first power port 114 and the second power port 115 onto the same printed circuit board 113, forming an inseparable whole. This allows the Jacquard driver 112 to not only have wireless power supply but also integrate adjustment functions when adjusting the pin pitch, improving the integration of the Jacquard driver 112, making good use of the space on the printed circuit board 113, reducing waste, and eliminating other adapter parts, thus improving response speed and achieving two benefits at once.

[0085] Example 6 differs from Example 1 in that:

[0086] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 The plug-in element 300 has a plurality of conductive first antioxidant layers 12. The first antioxidant layers 12 are electrically connected to the terminals of the piezoelectric Jacquard element 102 by plugging in, thereby making each first antioxidant layer 12 electrically connected to the corresponding piezoelectric Jacquard element 102.

[0087] Reference Figure 1 Figure 3 , Figure 8 , Figure 9 and Figure 10 The plug-in element 300 is pluggably mounted on the power terminal of the piezoelectric Jacquard element 102. Specifically, the plug-in element 300 includes a plurality of conductive first anti-oxidation layers 12, a housing 11, a plurality of slots 13 spaced apart in the housing 11, a plurality of first slot openings 14 spaced apart on one side surface of the housing 11, a plurality of second slot openings 15 spaced apart on the other side surface of the housing 11, a plurality of spaced solder pads 16, at least one second printed circuit board body 322 abutting against the other side surface of the housing 11, a plurality of output terminals on one side of the second printed circuit board body 322, a plurality of input terminals 19 on the other side of the second printed circuit board body 322, at least one first positioning post on the other side surface of the housing 11, at least one first positioning hole on the second printed circuit board body 322, and at least one second positioning post on the other side surface of the housing 11. The specific number of slots 13 is matched with the number of piezoelectric selector pieces. For example, when the number of piezoelectric selector pieces is 16, the number of slots 13 can be set to 16, which can be set as needed but is not limited to 16.

[0088] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The first slot 14, slot 13 and the second slot 15 are connected as one unit, and the first positioning hole is embedded in the second positioning post, so that the second printed circuit board body 322 is accurately attached to the other side of the outer shell 11.

[0089] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The first antioxidant layer 12 is electrically connected to the piezoelectric Jacquard element 102 by a plug-in connection, so that current flows through the first antioxidant layer 12 to the piezoelectric Jacquard element 102.

[0090] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 By setting a conductive first anti-oxidation layer 12, the plug element 300 can maintain good conductivity under long-term use, thereby extending the service life of the plug element 300 and improving the service life of the Jacquard device.

[0091] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, two first antioxidant layers 12 can be disposed on a specific pad 16. The two first antioxidant layers 12 are disposed on the pad 16 at intervals, with one first antioxidant layer 12 serving as the positive electrode and the other first antioxidant layer 12 serving as the negative electrode.

One end of the first copper sheet layer is disposed on the pad 16, and the other end of the first copper sheet layer extends toward the center of the slot 13.

[0093] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 By setting a first gold plating layer on the first copper sheet layer, on the one hand, the first gold plating layer itself has good conductivity, which can improve the conductivity of the first copper sheet layer; on the other hand, the first gold plating layer has good anti-oxidation properties, which can effectively protect the first copper sheet layer from oxidation during long-term use, thereby extending its service life and improving its stability, achieving a dual benefit.

[0094] By inserting the tail of the piezoelectric ceramic sheet 500 into the plug-in element 300, the copper foil terminal 501 is electrically connected to the first anti-oxidation layer 12.

The second copper sheet layer is disposed on the tail of the piezoelectric ceramic sheet 500, and the second gold plating layer is plated on the second copper sheet layer. In this embodiment, the first copper sheet layer and the second copper sheet layer are electrically connected in a pluggable manner.

[0096] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 One side of the slot 13 is connected to the first slot port 14, and the other side of the slot 13 is connected to the second slot port 15. The first anti-oxidation layer 12 is disposed in the slot 13. The piezoelectric Jacquard element 102 is inserted from the first slot port 14 and extends into the slot 13. Current is connected to the first anti-oxidation layer 12 from the second slot port 15.

[0097] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 By inserting the piezoelectric Jacquard element 102 from the first slot 14 and extending it into the slot 13, the piezoelectric Jacquard element 102 is less likely to fall out of the slot 13 after installation, thus making the electrical connection between the first anti-oxidation layer 12 and the piezoelectric Jacquard element 102 more secure and the installation process simple and convenient. On the other hand, during disassembly, the piezoelectric Jacquard element 102 can be directly pulled out, making maintenance more convenient and shortening the time required for maintenance, achieving a double benefit.

One side of the solder pad 16 is located on the second slot 15, and the other side of the solder pad 16 extends toward the inside of the slot 13. One end of the first anti-oxidation layer 12 is located on the solder pad 16, and the other end of the first anti-oxidation layer 12 extends obliquely toward the center of the slot 13.

[0099] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, each second slot 15 is provided with two pads 16, and each pad 16 is provided with a first anti-oxidation layer 12. Therefore, there are two relatively spaced pads 16 and two relatively spaced first anti-oxidation layers 12 in the slot 13. The two pads 16 extend along the inner walls of the left and right sides of the slot 13 respectively.

[0100] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The spacing between the slots 13 is equal to the spacing of the piezoelectric Jacquard element 102 mounted on the base 111.

Thus, the two first anti-oxidation layers 12 in the slots 13 are respectively clamped on the copper foil electrical terminals 501 on both sides of the tail of the piezoelectric Jacquard element 102, thereby making the copper foil electrical terminals 501 and the first anti-oxidation layer 12 electrically connected together. In this way, the electrical connection between the piezoelectric Jacquard element 102 and the plug-in element 300 can be quickly and conveniently completed through the plug-in action.

On the other hand, by setting the other end of the first anti-oxidation layer 12 to extend obliquely towards the center of the slot 13, it can be ensured that after plugging, the first anti-oxidation layer 12 and the copper foil electrical terminal 501 are tightly abutted together, thus ensuring stable power supply.
