Description

Technical Field

[0001] This invention relates to the field of welding processing technology, specifically to a welding processing device for a multi-mode lighting control circuit for a luminous desktop doll. Background Technology

[0002] As is well known, in order to meet the welding requirements of multi-mode lighting control circuits for luminous desktop dolls, the welding processing equipment is a type of professional equipment that can be used in an integrated or standalone manner. It includes soldering irons, multi-functional soldering stations and welding robots, which can specifically complete the welding operations of various components in the circuit, ensuring the quality and efficiency of circuit welding.

[0003] A search revealed a Chinese patent, CN119794691B, disclosing a welding fixture for electronic products. This patent includes a fixture body with support bases fixedly connected to its four corners. A control panel is fixedly mounted on the surface of the fixture body. A base plate is fixedly connected to one side of the top surface of the fixture body. A mounting plate is vertically fixedly connected to the top surface of the base plate. A pair of guide rails are fixedly connected to one side of the mounting plate. Slider blocks are slidably connected to the guide rails. A horizontal plate is fixedly connected between the sliders. The middle of the horizontal plate is threaded onto a first lead screw, which is rotatably connected to a first shaft seat. This invention has a reasonable structure and allows for the adjustment of electronic products through the assembly. The circuit board of the product is fixed, and then the adjustment component is installed on the drive component conveyor belt through the docking assembly. The drive component causes the conveyor belt to rotate the adjustment component, which facilitates the soldering gun to process the circuit board of the electronic product. The multi-mode lighting control circuit of the luminous desktop doll is a control system composed of multiple wires and circuit boards. During the soldering process, multiple wires are soldered side by side to the circuit board to form the control system. The problem with the existing technology is that due to the lack of a structure for continuously transporting and aligning multiple wires and circuit boards, it is impossible to continuously align the wires and circuit boards when soldering multiple wires and circuit boards, thus reducing the flexibility when continuously soldering multiple rows of multiple wires and circuit boards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a welding processing device for a multi-mode lighting control circuit for a luminous desktop doll. This device has a structure that continuously feeds and aligns multiple wires to a circuit board, thus enabling continuous alignment of the wires and circuit board during welding, thereby improving the flexibility of continuously welding multiple rows of wires to a circuit board.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a welding processing device for a multi-mode lighting control circuit for a luminous desktop doll, comprising a welding platform, a feeding mechanism on the left side of the top of the welding platform, and a wire feeding mechanism on the right side of the top of the welding platform. The feeding mechanism includes an air extraction component, a flow guiding component, a follower component, and a loading component. The air extraction component is located on the left side of the top of the welding platform, the flow guiding component is located on top of the air extraction component, the follower component is located on top of the flow guiding component, and the loading component is located on top of the follower component. The wire feeding mechanism includes a transmission component, a guide component, a power supply component, a wire laying component, and a positioning component. The transmission component is located on the right side of the top of the welding platform, the guide component is located on top of the transmission component, the power supply component is located on top of the guide component, the wire laying component is located on top of the power supply component, and the positioning component is located on top of the wire laying component.

[0006] By adopting the above technical solution, and by setting up a feeding mechanism and a wire feeding mechanism, the feeding mechanism can continuously transport circuit boards, and the wire feeding mechanism can continuously feed multiple wires arranged in a row, and bring the wires into contact with the solder joints of the circuit board, thereby facilitating the continuous soldering of the circuit board and multiple wires by the soldering platform.

[0007] The present invention is further configured such that: the exhaust assembly includes a limiting base plate, an exhaust fan and an exhaust pipe, the limiting base plate is bolted to the left side of the top of the welding platform, the exhaust fan is bolted to the left side of the top of the limiting base plate, and the exhaust pipe is connected to the input end of the exhaust fan.

[0008] By adopting the above technical solution, the limiting base plate can form an air extraction structure with the exhaust fan and exhaust pipe by setting an air extraction component. The limiting base plate provides support for the drainage tube and the exhaust fan. The exhaust fan is a small high-pressure exhaust device with a power of 500-800W to ensure that a stable negative pressure of -30~-50kPa is generated at the concave top drainage base. This allows the exhaust fan to extract the air in the drainage tube through the exhaust pipe, providing negative pressure adsorption force for limiting the circuit board at the concave top drainage base. This can not only firmly adsorb the circuit board, but also efficiently suck up welding fumes.

[0009] The present invention is further configured such that: the drainage assembly includes a drainage cylinder, a support tray and a thrust roller bearing; the drainage cylinder is bolted to the top of the limiting base plate; the left side of the drainage cylinder is connected to the right side of the exhaust pipe; the support tray is bolted to the top of the surface of the drainage cylinder; and the thrust roller bearing is rotatably connected to the top of the support tray.

[0010] By adopting the above technical solution, by setting the diversion component, the diversion cylinder can form a structure supporting the follower component together with the support tray and the thrust roller bearing. By supporting the support tray with the diversion cylinder, the thrust roller bearing can provide support for the follower gear disk along the support tray, and the follower gear disk can rotate with the thrust roller bearing.

[0011] The present invention is further configured such that: the follower assembly includes a follower gear disk, a flow guiding ring, and a flow guide plate; the follower gear disk is bolted to the top of the thrust roller bearing; the flow guiding ring is bolted to the top of the follower gear disk; and six flow guide plates are respectively welded to the inner side of the flow guiding ring.

[0012] By adopting the above technical solution, by setting a follower component, the follower gear disk can form a structure supporting the loading component together with the flow guiding ring and the flow guide plate. The follower gear disk rotates synchronously with the transmission of the guide gear disk, which can drive the flow guiding ring and the flow guide plate to rotate together. The flow guiding ring can provide support for the loading component, and at the same time, it can drive the loading component to rotate together when rotating, so as to achieve the effect of making the loading component drive the circuit board to move continuously together.

[0013] The present invention is further configured such that: the loading assembly includes a through-hole closed top plate, a concave top drainage base and an intercepting mesh plate, the through-hole closed top plate is bolted to the top of the drainage ring, the six concave top drainage bases are respectively connected to the top of the through-hole closed top plate, and the intercepting mesh plate is bolted to the top of the concave top drainage base.

[0014] Using the above technical solution, by setting up a loading assembly, the through-hole sealed top plate can form a structure for transporting circuit boards together with the concave top drainage base and the intercepting mesh plate. The air drainage structure formed by the through-hole sealed top plate and the concave top drainage base allows the concave top drainage base to draw air from the intercepting mesh plate into the through-hole sealed top plate when the exhaust fan draws air out. The air is then guided into the drainage cylinder by the guide plate and finally discharged from the exhaust fan through the exhaust pipe. The top of the concave top drainage base has an inwardly inclined groove, which can be used to guide the movement of the circuit board during placement on the intercepting mesh plate, directing the circuit board directly above the intercepting mesh plate. When negative pressure is generated when air flows into the concave top drainage base, the intercepting mesh plate can use this negative pressure to adhere the circuit board above it. While limiting the position of the circuit board, the negative pressure can also draw in fumes generated during the welding process, which then pass through the intercepting mesh plate. If the intercepting mesh plate becomes clogged after long-term use, it can be replaced with a new one.

[0015] The present invention is further configured such that: the transmission assembly includes a positioning base plate, a servo motor and a transmission base, the positioning base plate is bolted to the right side of the top of the welding platform, the servo motor is bolted to the top of the positioning base plate, and the transmission base is bolted to the output end of the top of the servo motor.

[0016] By adopting the above technical solution, and by setting up a transmission component, the positioning base plate can form a structure with the servo motor and the transmission base to drive the rotation of the guide component. By fixing the servo motor on the right side of the top of the welding platform through the positioning base plate, the servo motor can drive the transmission base to rotate, which in turn drives the guide gear disk and the guide support top plate connected to it to rotate together. This achieves the effect of driving the T-shaped box to rotate by rotating the guide support top plate, which can provide continuous conveying power for the T-shaped box containing multiple wires, and can also provide power for the rotation of the follower gear disk driven by the guide gear disk.

[0017] The present invention is further configured such that: the guiding assembly includes a guiding gear disk, a guiding support top plate and an assembly inner groove, the guiding gear disk is bolted to the bottom of the transmission base surface, the guiding support top plate is bolted to the top of the transmission base surface, and six assembly inner grooves are respectively opened at the bottom of the guiding support top plate.

[0018] By adopting the above technical solution, the guide gear disk, together with the guide support top plate and the assembly inner groove, forms a structure that provides transmission for the follower gear disk. As the guide gear disk and the guide support top plate rotate with the transmission base, they can drive the follower gear disk to rotate together, so that the follower gear disk rotates at the same speed in the opposite direction of the guide gear disk. This ensures that the circuit board driven by the left and right concave top drainage bases is always in contact with the multiple wires in the leftmost T-shaped box during movement, which is beneficial for the welding platform to weld the circuit board and the multiple wires. The assembly inner groove can provide installation and movement space for the brush, so that the brush can always be kept on top of the conductive slip ring.

[0019] The present invention is further configured such that: the power supply component includes a fixed housing, a conductive slip ring, and a brush; the fixed housing is rotatably connected to the surface of the transmission base; the bottom of the fixed housing is close to the top of the guide gear disk; the conductive slip ring is bolted to the inner side of the fixed housing; the brush is bolted to the inner side of the assembly inner groove; and the bottom of the brush contacts the top of the conductive slip ring.

[0020] By adopting the above technical solution, and by setting up a power supply component, the fixed housing can form a structure that provides power to the electric cylinder together with the conductive slip ring and the brush. The fixed housing is connected to an external power supply device, and both the fixed housing and the power supply device remain fixed and stationary. The fixed housing is mounted on the bearing seat of the transmission base, and the transmission base can rotate relative to the fixed housing. The bottom of the fixed housing is close to the top of the guide gear disk. The conductive slip ring is bolted to the inside of the fixed housing, and the brush is bolted to the inside of the assembly groove. The bottom of the brush contacts the top of the conductive slip ring. By setting up a power supply component, the fixed housing can form a structure that provides power to the electric cylinder together with the conductive slip ring and the brush. The rotation of the transmission base relative to the fixed housing drives the gear disk and the guide support top plate to rotate, while the fixed housing remains stationary. This allows the fixed housing to not rotate synchronously with the guide gear disk and the guide support top plate. When the fixed housing is connected to the external power supply device, it remains stationary with the power supply device, thereby allowing the power supply device to stably provide power support to the conductive slip ring, and the conductive slip ring to stably provide power support to the brush. The brush can provide power support to the electric cylinder through wires and can rotate together with the guide support top plate.

[0021] The present invention is further configured such that: the wiring assembly includes electric cylinders, a Z-shaped support plate, a T-shaped box, and a combing plate; six electric cylinders are respectively bolted to the top of the fixed housing; the electric cylinders are connected to the brushes via wires; the Z-shaped support plate is bolted to the output end of the top of the electric cylinders; the T-shaped box is bolted to the side of the Z-shaped support plate away from the electric cylinders; and the combing plate is bolted to the side of the T-shaped box away from the electric cylinders.

[0022] By adopting the above technical solution, and by setting up a wiring assembly, the electric cylinder can form a structure for continuously conveying wires together with the Z-shaped support plate, the T-shaped box, and the comb plate. The temporary wire storage structure composed of the T-shaped box and the comb plate can provide temporary support and storage for short wires used for circuit board soldering. When the comb plate and the concave top drain base are close to each other, the wires can be placed at the soldering point of the circuit board. The height adjustment structure composed of the electric cylinder and the Z-shaped support plate can allow the electric cylinder to drive the Z-shaped support plate to adjust the height of the T-shaped box, thereby allowing the T-shaped box to further adapt the wires to the position of the circuit board.

[0023] The present invention is further configured such that: the positioning component includes a limiting rod, a reset torsion spring, a T-shaped cover plate, and a wire-fixing comb plate; the limiting rod is bolted to the side of the T-shaped box near the electric cylinder; the reset torsion spring is welded to both sides of the inner side of the limiting rod; the T-shaped cover plate is rotatably connected between the opposite sides of the limiting rod; the opposite sides of the reset torsion spring are welded to the T-shaped cover plate; the wire-fixing comb plate is bolted to the side of the T-shaped cover plate near the comb plate; and an elastic rubber pad is adhered to the inner side of the comb plate.

[0024] By adopting the above technical solution, and by setting a positioning component, the limiting rod can form a structure for limiting multiple wires together with the reset torsion spring, the T-shaped cover plate, and the wire fixing comb plate. Through the reset structure formed by the limiting rod and the reset torsion spring, the T-shaped cover plate can drive the wire fixing comb plate to open upward from the T-shaped box along the limiting rod, so that the wire can be placed into the comb plate. And through the reset torsion spring using the limiting rod as a support point, the T-shaped cover plate is closed downward with the T-shaped box by its own elasticity, so that the wire fixing comb plate can press the wires in the comb plate. The pressing of the wires by the wire fixing comb plate achieves further limiting of the wires. Furthermore, the elastic rubber pad inside can further adapt to wires of different diameters by utilizing the elastic deformation of the rubber, while improving the stability of the limiting.

[0025] Compared with the prior art, the present invention provides a welding processing device for a multi-mode lighting control circuit for a luminous desktop doll, which has the following beneficial effects: This is a welding processing device for a multi-mode lighting control circuit of a luminous desktop doll. It includes a welding platform and a feeding mechanism. The welding platform is a welding robot and its supporting structure, as used in existing technologies. The welding robot can weld circuit boards and wires. A circuit board conveying structure composed of an air extraction component, a flow guiding component, a follow-up component, and a loading component; and an air conveying structure composed of a limiting base plate, an exhaust fan, and an exhaust pipe, can extract air from the concave top flow guiding base, creating negative pressure. An air guiding structure composed of a flow guiding cylinder, a support tray, and a thrust roller bearing guides the air from the concave top flow guiding base to the exhaust pipe, and then discharges it through the exhaust fan. Furthermore, the thrust roller bearing, with the support tray as a fulcrum, can rotate the follow-up gear disk. The conveying structure, consisting of a follower gear disk, a diversion ring, and a guide plate, provides guidance and support. The follower gear disk rotates in the opposite direction along with the guide gear disk, thereby driving the diversion ring to rotate the through-hole closed top plate synchronously. The guide plate can concentrate the air drawn in from the concave top diversion base and introduce it into the diversion cylinder. The circuit board continuous conveying structure, consisting of the through-hole closed top plate, the concave top diversion base, and the interception mesh plate, allows the concave top diversion base to draw in air from the interception mesh plate using negative pressure. When placing the circuit board on the interception mesh plate, the negative pressure temporarily fixes it to the interception mesh plate. Furthermore, when the through-hole closed top plate rotates with the diversion ring, it can drive the concave top diversion base to move in a circular motion, ultimately achieving the effect of continuously conveying the circuit board along a circular motion trajectory. This is a welding and processing device for a multi-mode lighting control circuit for a luminous desktop doll. By setting a wire feeding mechanism, the transmission component, guide component, power supply component, wiring component, and positioning component can form a structure with multiple wires arranged and continuously fed. Through the transmission structure composed of a positioning base plate, a servo motor, and a transmission base, the servo motor can rotate the transmission base with the positioning base plate as a support point. This allows the transmission base to drive the guide gear disk and guide support top plate to rotate synchronously. Through the transmission structure composed of the guide gear disk, guide support top plate, and assembly inner groove, the guide gear disk can drive the follower gear disk to rotate in the opposite direction at the same speed. The guide support top plate can rotate synchronously with the rotation of the transmission base, driving the wiring component and positioning component to rotate, allowing the wiring component and positioning component to move circumferentially on the top of the guide support top plate. The assembly inner groove provides movement space for the brush, thus driving the brush to rotate synchronously with the guide support top plate. The device is connected to a fixed outer shell, conductive slip ring, and... The power supply structure composed of brushes can limit the conductive slip ring by using the power supply equipment as a support point when the fixed housing is connected to the power supply equipment. The conductive slip ring supplies power to the brush, which in turn supplies power to the electric cylinder. The height adjustment structure composed of the electric cylinder, Z-shaped support plate, T-shaped box, and comb plate allows the electric cylinder to drive the Z-shaped support plate to adjust the height of the T-shaped box, so that the T-shaped box can be adapted to the position of the circuit board, allowing the wires to contact the solder joints of the circuit board. The comb plate can separate and arrange each wire, thus providing stable limiting for multiple wires at the same time. The wire limiting structure composed of limiting rod, return torsion spring, T-shaped cover plate, and wire fixing comb plate allows the T-shaped cover plate to open along the limiting rod. After the wire is placed in the comb plate, the spring force of the return torsion spring resets the T-shaped cover plate, allowing the T-shaped cover plate to drive the top of the wire fixing comb plate and the T-shaped box to close. Finally, the wire fixing comb plate presses down on each wire in the comb plate, achieving the effect of limiting each wire. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please see Figures 1-4A welding processing device for a multi-mode lighting control circuit for a luminous desktop doll includes a welding platform 1. A feeding mechanism 2 is located on the left side of the top of the welding platform 1. The feeding mechanism 2 includes an air extraction component 21, a flow guiding component 22, a follower component 23, and a loading component 24. The air extraction component 21 is located on the left side of the top of the welding platform 1, the flow guiding component 22 is located on top of the air extraction component 21, the follower component 23 is located on top of the flow guiding component 22, and the loading component 24 is located on top of the follower component 23. By setting up the welding platform 1 and the feeding mechanism 2, the welding platform 1 is a prior art device. The welding robot and its supporting platform structure allow for welding of circuit boards and wires. A circuit board conveying structure consisting of an extraction assembly 21, a flow guide assembly 22, a follow-up assembly 23, and a loading assembly 24, along with an air conveying structure consisting of a limiting base plate 211, an exhaust fan 212, and an exhaust pipe 213, can extract air from the concave top flow guide base 242, creating negative pressure. An air guiding structure consisting of a flow guide cylinder 221, a support tray 222, and a thrust roller bearing 223 can guide the air from the concave top flow guide base 242. The air guide exhaust pipe 213 at position 42 then discharges the air through the exhaust fan 212. The thrust roller bearing 223, using the support tray 222 as a fulcrum, guides and supports the rotation of the follower gear disk 231. The conveying structure formed by the follower gear disk 231, the guide ring 232, and the guide plate 233 allows the follower gear disk 231 to rotate in the opposite direction along with the guide gear disk 321. This drives the guide ring 232 to synchronously rotate the through-hole sealed top plate 241, and the guide plate 233 draws in air from the concave top guide base 242. The air-concentrated intake tube 221, the through-hole sealed top plate 241, the concave top intake base 242, and the intercepting mesh plate 243 form a continuous circuit board conveying structure. The concave top intake base 242 can use negative pressure to draw air from the intercepting mesh plate 243, so that when the circuit board is placed on the intercepting mesh plate 243, it is temporarily fixed on the intercepting mesh plate 243 by negative pressure. When the through-hole sealed top plate 241 rotates with the intake ring 232, it drives the concave top intake base 242 to move in a circle, ultimately achieving the effect of continuously conveying the circuit board along a circular movement trajectory.

[0030] Please see Figure 3The air extraction assembly 21 includes a limiting base plate 211, an exhaust fan 212, and an exhaust pipe 213. The limiting base plate 211 is bolted to the left side of the top of the welding platform 1, the exhaust fan 212 is bolted to the left side of the top of the limiting base plate 211, and the exhaust pipe 213 is connected to the input end of the exhaust fan 212. By setting the air extraction assembly 21, the limiting base plate 211, the exhaust fan 212, and the exhaust pipe 213 can form an air extraction structure, through which the limiting base plate 211 provides air delivery. The drainage tube 221 and the exhaust fan 212 provide support. The exhaust fan 212 is a small high-pressure exhaust device with a power of 500-800W to ensure that a stable negative pressure of -30~-50kPa is generated at the concave top drainage base. This allows the exhaust fan 212 to extract the air in the drainage tube 221 through the exhaust pipe 213, providing negative pressure adsorption force for limiting the circuit board at the concave top drainage base 242. This can firmly adsorb the circuit board and efficiently suck up welding fumes.

[0031] Please see Figure 3 The diversion assembly 22 includes a diversion cylinder 221, a support tray 222, and a thrust roller bearing 223. The diversion cylinder 221 is bolted to the top of the limiting base plate 211. The left side of the diversion cylinder 221 is connected to the right side of the exhaust pipe 213. The support tray 222 is bolted to the top of the surface of the diversion cylinder 221. The thrust roller bearing 223 is rotatably connected to the top of the support tray 222. By setting the diversion assembly 22, the diversion cylinder 221, the support tray 222, and the thrust roller bearing 223 can form a structure that supports the follower assembly 23. By supporting the support tray 222 with the diversion cylinder 221, the thrust roller bearing 223 can provide support for the follower gear disk 231 along the support tray 222, and allow the follower gear disk 231 to rotate with the thrust roller bearing 223.

[0032] Please see Figure 4 The follower assembly 23 includes a follower gear disk 231, a flow-guiding ring 232, and a flow-guiding plate 233. The follower gear disk 231 is bolted to the top of the thrust roller bearing 223, and the flow-guiding ring 232 is bolted to the top of the follower gear disk 231. Six flow-guiding plates 233 are welded to the inner side of the flow-guiding ring 232. By setting the follower assembly 23, the follower gear disk 231 can form a structure that supports the loading assembly 24 together with the flow-guiding ring 232 and the flow-guiding plates 233. The follower gear disk 231 rotates synchronously with the transmission of the guide gear disk 321, which can drive the flow-guiding ring 232 and the flow-guiding plates 233 to rotate together. The flow-guiding ring 232 can provide support for the loading assembly 24 and can also drive the loading assembly 24 to rotate together when rotating, so as to achieve the effect of the loading assembly 24 driving the circuit board to move continuously together.

[0033] Please see Figure 4The loading assembly 24 includes a through-hole sealed top plate 241, a recessed top drainage base 242, and an intercepting mesh plate 243. The through-hole sealed top plate 241 is bolted to the top of the drainage ring 232. Six recessed top drainage bases 242 are respectively connected to the top of the through-hole sealed top plate 241. The intercepting mesh plate 243 is bolted to the top of the recessed top drainage base 242. By setting the loading assembly 24, the through-hole sealed top plate 241, the recessed top drainage base 242, and the intercepting mesh plate 243 can form a transport circuit board structure. Through the air drainage structure formed by the through-hole sealed top plate 241 and the recessed top drainage base 242, when the exhaust fan 212 draws out air, the recessed top drainage base 242 can draw the air from the intercepting mesh plate 243 into the through-hole sealed top plate 241, and then... The airflow is guided into the guide tube 221 through the guide plate 233 and finally discharged from the exhaust fan 212 through the exhaust pipe 213. The top of the concave top guide base 242 is provided with an inwardly inclined groove, which can be used to guide the movement of the circuit board during the process of placing the circuit board on the interception mesh plate 243, guiding the circuit board to be directly above the interception mesh plate 243. When the air flows into the concave top guide base 242 and a negative pressure is generated, the circuit board can be attracted to the top of the interception mesh plate 243 by the negative pressure. While limiting the position of the circuit board, the negative pressure can also suck in the fumes generated during the welding process and pass them through the interception mesh plate 243. When the interception mesh plate 243 itself becomes blocked due to long-term use, it can be replaced with a new one.

[0034] The working principle of this embodiment is as follows: First, when a circuit board needs to be transported, it is placed on the interceptor mesh plate 243 within each recessed top drainage base 242. Then, the exhaust fan 212 is activated, drawing air out of the recessed top drainage base 242. The air then enters the through-hole sealed top plate 241 from the recessed top drainage base 242, is guided by the guide plate 233 into the drainage cylinder 221, and finally exits from the exhaust fan 212 through the exhaust pipe 213. At this time, a negative pressure is generated above the interceptor mesh plate 243, causing the circuit board to adhere to the interceptor mesh plate 243 due to the negative pressure. Then, when the guide gear disk 321 rotates, the follower gear disk 231 will rotate in the same speed but in the opposite direction as the guide gear disk 321, and drive the drainage ring 232 to rotate the through hole sealing top plate 241 synchronously. At this time, the concave top drainage base 242 will move in a circle with the rotation of the through hole sealing top plate 241. The concave top drainage base 242 will drive the circuit board to gradually move to the far right until the solder joint on the circuit board contacts the wire on the comb plate 344. Then, the welding robot on the welding platform 1 will weld the solder joint on the circuit board and the contact point with the wire.

[0035] Example 2: Based on Example 1, and referring to Figures 5-8A welding processing device for a multi-mode lighting control circuit for a luminous desktop doll also includes a wire feeding mechanism 3. The wire feeding mechanism 3 includes a transmission component 31, a guide component 32, a power supply component 33, a wire routing component 34, and a positioning component 35. The transmission component 31 is located on the right side of the top of the welding platform 1, the guide component 32 is located on top of the transmission component 31, the power supply component 33 is located on top of the guide component 32, the wire routing component 34 is located on top of the power supply component 33, and the positioning component 35 is located on top of the wire routing component 34. By setting the wire feeding mechanism 3, the transmission component 31, the guide component 32, the power supply component 33, the wire routing component 34, and the positioning component 35 can form a structure in which multiple wires are arranged and continuously fed, via a positioning base plate. The transmission structure consisting of servo motor 312 and transmission base 313, with positioning base 311 as the support point, allows servo motor 312 to rotate transmission base 313. This, in turn, allows transmission base 313 to drive guide gear disk 321 and guide support top plate 322 to rotate synchronously. Through the transmission structure consisting of guide gear disk 321, guide support top plate 322, and assembly inner groove 323, guide gear disk 321 can drive follower gear disk 231 to rotate in the opposite direction at the same speed. Guide support top plate 322, rotating with transmission base 313, synchronously drives cable assembly 34 and positioning assembly 35 to rotate, allowing cable assembly 34 and positioning assembly 35 to rotate circumferentially on top of guide support top plate 322. The movable inner groove 323 provides space for the brush 333 to move, allowing it to rotate synchronously with the guide support plate 322. The power supply structure consisting of the fixed housing 331, the conductive slip ring 332, and the brush 333 allows the conductive slip ring 332 to be limited by the power supply equipment when the fixed housing 331 is connected to it. The conductive slip ring 332 then supplies power to the brush 333, which in turn supplies power to the electric cylinder 341. The height adjustment structure consisting of the electric cylinder 341, the Z-shaped support plate 342, the T-shaped box 343, and the comb plate 344 allows the electric cylinder 341 to move the Z-shaped support plate 342 to adjust the height of the T-shaped box 343, thus allowing the T-shaped box 343 to rotate synchronously with the guide support plate 322. Box 343 adapts to the position of the circuit board, allowing the wires to contact the solder joints of the circuit board. Comb plate 344 can separate and arrange each wire, thus providing stable limiting for multiple wires simultaneously. The wire limiting structure composed of limiting rod 351, reset torsion spring 352, T-shaped cover plate 353 and fixed comb plate 354 allows T-shaped cover plate 353 to open along limiting rod 351. After the wire is placed in comb plate 344, the elastic force of reset torsion spring 352 resets T-shaped cover plate 353, allowing T-shaped cover plate 353 to drive fixed comb plate 354 and the top of T-shaped box 343 to close. Finally, fixed comb plate 354 presses down on each wire in comb plate 344, achieving the effect of limiting each wire.

[0036] Please see Figure 6 The transmission assembly 31 includes a positioning base plate 311, a servo motor 312, and a transmission base 313. The positioning base plate 311 is bolted to the right side of the top of the welding platform 1, the servo motor 312 is bolted to the top of the positioning base plate 311, and the transmission base 313 is bolted to the output end of the top of the servo motor 312. By setting the transmission assembly 31, the positioning base plate 311, the servo motor 312, and the transmission base 313 can form a structure that drives the guide assembly 32 to rotate. By fixing the servo motor 312 to the right side of the top of the welding platform 1 through the positioning base plate 311, the servo motor 312 can drive the transmission base 313 to rotate, which in turn drives the guide gear disk 321 and the guide support top plate 322 connected to it to rotate together. This achieves the effect of driving the T-shaped box 343 to rotate by rotating the guide support top plate 322, which can provide continuous conveying power for the T-shaped box 343 containing multiple wires, and can also provide power for the guide gear disk 321 to drive the rotation of the follower gear disk 231.

[0037] Please see Figure 6 The guide assembly 32 includes a guide gear disk 321, a guide support top plate 322, and assembly inner grooves 323. The guide gear disk 321 is bolted to the bottom of the surface of the transmission base 313, and the guide support top plate 322 is bolted to the top of the surface of the transmission base 313. Six assembly inner grooves 323 are respectively formed at the bottom of the guide support top plate 322. By setting the guide assembly 32, the guide gear disk 321, the guide support top plate 322, and the assembly inner grooves 323 can form a structure that provides transmission for the follower gear disk 231. As the transmission base 313 rotates, it drives the follower gear disk 231 to rotate together, so that the follower gear disk 231 rotates at the same speed in the opposite direction of the guide gear disk 321. This ensures that the circuit board driven by the left and right concave top drainage bases 242 is always in contact with the multiple wires in the leftmost T-shaped box 343 during movement, which is beneficial for the welding platform 1 to weld the circuit board and the multiple wires. The assembly inner groove 323 can provide installation and movement space for the brush 333, so that the brush 333 can always be kept on top of the conductive slip ring 332.

[0038] Please see Figure 7The power supply component 33 includes a fixed housing 331, a conductive slip ring 332, and a brush 333. The fixed housing 331 is connected to an external power supply device and remains stationary with the power supply device. The fixed housing 331 is mounted on a bearing seat of a transmission base 313, and the transmission base 313 can rotate relative to the fixed housing 331. The bottom of the fixed housing 331 is close to the top of the guide gear disk 321. The conductive slip ring 332 is bolted to the inner side of the fixed housing 331, and the brush 333 is bolted to the inner side of the assembly groove 323. The bottom of the brush 333 contacts the top of the conductive slip ring 332. By setting the power supply component 33, the fixed housing 331 can be assembled with the conductive slip ring 332 and the brush 333. The structure that provides power to the electric cylinder 341 rotates the gear disk 321 and the guide support top plate 322 by rotating the transmission base 313 relative to the fixed housing 331, while the fixed housing 331 remains stationary. This allows the fixed housing 331 to rotate asynchronously with the guide gear disk 321 and the guide support top plate 322. When the fixed housing 331 is connected to an external power supply device, it remains stationary with the power supply device, thereby allowing the power supply device to stably provide power to the conductive slip ring 332, and the conductive slip ring 332 to stably provide power to the brush 333. The brush 333 can provide power to the electric cylinder 341 through wires and can rotate together with the guide support top plate 322.

[0039] Please see Figure 8 The wiring assembly 34 includes electric cylinders 341, a Z-shaped support plate 342, a T-shaped box 343, and a combing plate 344. Six electric cylinders 341 are bolted to the top of the fixed housing 331. Each electric cylinder 341 is connected to a brush 333 via wires. The Z-shaped support plate 342 is bolted to the output end of the top of the electric cylinders 341. The T-shaped box 343 is bolted to the side of the Z-shaped support plate 342 away from the electric cylinders 341. The combing plate 344 is bolted to the side of the T-shaped box 343 away from the electric cylinders 341. By setting up the wiring assembly 34, the electric cylinders 341 can be connected to the Z-shaped support plate 342, the T-shaped box 343, and the combing plate 344. The T-shaped box 343 and the comb plate 344 form a continuous wire conveying structure. The T-shaped box 343 and the comb plate 344 form a temporary wire storage structure for multiple wires, which can provide temporary support and storage for short wires used for circuit board soldering. When the comb plate 344 and the concave top drain base 242 are close to each other, the wires can be placed at the soldering point of the circuit board. The height adjustment structure formed by the electric cylinder 341 and the Z-shaped support plate 342 can drive the Z-shaped support plate 342 to adjust the height of the T-shaped box 343, so that the T-shaped box 343 can drive the wires to further adapt to the position of the circuit board.

[0040] The positioning component 35 includes a limiting rod 351, a reset torsion spring 352, a T-shaped cover plate 353, and a wire-fixing comb plate 354. The limiting rod 351 is bolted to the side of the T-shaped box 343 near the electric cylinder 341. The reset torsion spring 352 is welded to both sides of the inner side of the limiting rod 351. The T-shaped cover plate 353 is rotatably connected between the opposite sides of the limiting rod 351. The opposite sides of the reset torsion spring 352 are welded to the T-shaped cover plate 353. The wire-fixing comb plate 354 is bolted to the side of the T-shaped cover plate 353 near the comb plate 344. An elastic rubber pad is adhered to the inner side of the comb plate 344. By setting the positioning component 35, the limiting rod 351 can form a combination with the reset torsion spring 352, the T-shaped cover plate 353, and the wire-fixing comb plate 354. The structure for limiting multiple wires utilizes a reset structure composed of a limiting rod 351 and a reset torsion spring 352. This allows the T-shaped cover 353 to drive the wire-fixing comb plate 354 upward along the limiting rod 351 from the T-shaped box 343, thus allowing the wires to be placed inside the comb plate 344. The reset torsion spring 352, using the limiting rod 351 as a support point, uses its own elasticity to close the T-shaped cover 353 downward to the T-shaped box 343. This allows the wire-fixing comb plate 354 to press the wires inside, further limiting their movement. Furthermore, the internal elastic rubber pad can adapt to different wire diameters through its elastic deformation, improving the stability of the limiting mechanism.

[0041] The working principle of this embodiment is as follows: First, the servo motor 312 and the electric cylinder 341 are connected to an external PLC controller and power supply. When it is necessary to feed the wires, the T-shaped cover plate 353 is opened upwards, and multiple wires are placed into the comb plate 344 in sequence until the number of wires in the comb plate 344 reaches the current welding requirement. Then, the T-shaped cover plate 353 is released, and the T-shaped cover plate 353 will be driven by the elastic force of the return torsion spring 352 to return to the top of the T-shaped box 343 until the wire comb plate 354 contacts the wires as the T-shaped cover plate 353 moves. Then, the fixed housing 331 is connected to an external power supply and fixed to it. At this time, the conductive slip ring 332 will supply power to the brush 333, and the brush 333 will supply power to the electric cylinder 341. Then, the servo motor 312 is started by the PLC controller and its power supply is adjusted accordingly. Under control, the servo motor 312 will drive the transmission base 313 to rotate the guide gear disk 321 and the guide support top plate 322. At this time, the guide gear disk 321 will drive the follower gear disk 231 to rotate, and the guide support top plate 322 will drive the electric cylinder 341 to move in a circle. The electric cylinder 341 will drive the Z-shaped support plate 342, the T-shaped box 343, the comb plate 344 and the positioning component 35 to move together until the T-shaped box 343 moves to the leftmost side of the guide support top plate 322 and the wires in the comb plate 344 are close to the solder joint of the circuit board on the interception mesh plate 243. Then, the servo motor 312 will be paused, and the electric cylinder 341 will be controlled to drive the Z-shaped support plate 342 to rise and fall. The Z-shaped support plate 342 will drive the T-shaped box 343 and the comb plate 344 to rise and fall together until the wires in the comb plate 344 contact the solder joint of the circuit board.
