Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The following is a special explanation of some technical features in the embodiments: the movement of various devices on the XYZ axes in the embodiments is achieved by various cylinder modules, servo motor modules and lead screw modules. Cylinder modules, servo motor modules and lead screw modules are conventional technical means in the field. They are matched or assembled with each other according to requirements. They can be purchased on the market and belong to the prior art. Therefore, they are not described in detail in principle.

[0037] refer to Figures 1-3 An automated copper wire assembly device for a seat heating pad includes at least an assembly machine mounting frame 1. The process equipment mounted on the assembly machine mounting frame 1 sequentially includes manual wire adjustment, terminal crimping, terminal waste tape cutting, excess copper wire cutting, resistance welding, visual inspection, and heat shrink tubing heat sealing. A conveying module 3 runs through all the above processes, automatically transporting the heating pad from the conveying fixture 323 to the output of each process equipment. The conveying module 3 includes two lifting modules 32, located at the first and last positions of the process, respectively. A conveying track 31 connects the two lifting modules 32. The conveying track 31 is segmented, including an independent conveying track one 311 and an independent conveying track two 312. A conveying fixture 323 is mounted on the conveying track 31, and a wire clamping fixture 324 is mounted on one side of the conveying fixture 323. The conveying fixture 323 moves on the conveying track 31. The conveying track 31 is existing technology and will not be described in detail here.

[0038] refer to Figure 5 The lifting module 32 includes a lifting housing. A rodless cylinder module 321 is installed on the inner wall of the lifting housing. The output end of the rodless cylinder module 321 is equipped with a conveying mounting frame 322 and controls the movement of the conveying mounting frame 322 on the Z-axis. An independent conveying track 311 is installed on the conveying mounting frame 322. A conveying fixture 323 is installed on the independent conveying track 311, and the travel direction of the independent conveying track 311 is on the X-axis. A wire clamping fixture 324 for clamping the copper wire on the heating pad is also installed on the conveying fixture 323. The conveying track 31 is arranged in a ring. The conveying fixture 323 is transported from the front lifting module and conveyed to each process and then enters the rear lifting module. The rear lifting module then transports the conveying fixture 323 back to the front lifting module through the conveying track 31 to complete the cycle.

[0039] refer to Figures 2-3 First, there is the wire adjustment module 2, which contains at least two manual workstations and matching workbenches. The front lifting module is installed on one side of the workbenches. Next to the workbenches, there is a button to control the start and stop of the conveyor track 31 installed on the wire adjustment module 2. When the front lifting module delivers the conveyor fixture 323 to the workbenches, the operator presses the button to stop the conveyor track 31. Then, the operator uses a heating pad to perform tasks such as wire arrangement and wire picking, dividing the copper wire into multiple groups. Each group of copper wires contains one thick and one thin wire, arranged vertically. The heating pad is placed on the conveyor fixture 323, and the copper wires are clamped on the wire clamping fixture 324, ensuring that all copper wires are flush. Each group of copper wires is evenly spaced at 12mm intervals, and the front end of the copper wire protrudes 15mm from the wire clamping fixture 324. After completing the above process, the operator presses the button to allow the conveyor track 31 to continue conveying and proceed to the next process.

[0040] refer to Figure 4 and Figure 6The conveyor track 31 in this section is an independently moving independent conveyor track 311, meaning that the driving power on this independent conveyor track 311 is separate. When the conveyor fixture 323 enters the terminal crimping module 4, the sensor on the independent conveyor track 311 will detect it, thereby activating the brake cylinder 47 and causing the output shaft to rise. A matching stop is provided on the bottom side of the conveyor fixture 323, which can prevent the conveyor fixture 323 from moving further. A groove is provided on the assembly machine mounting frame 1, and a longitudinal shaft frame 44 is installed on the bottom side wall of the groove. The longitudinal shaft frame 44 is controlled by the longitudinal axis servo motor module 46 to move along the Y-axis direction, and a transverse axis lead screw is installed on the longitudinal shaft frame 44. Block 45, the output end of the horizontal axis screw module 45 is equipped with a horizontal axis frame 43. The horizontal axis screw module 45 controls the horizontal axis frame 43 to move on the X-axis. The horizontal axis frame 43 is equipped with a lifting frame 48, which is used to lift the conveying fixture 323 upward in the Z-axis direction. The driving force is a cylinder. When the conveying fixture 323 moves to the terminal crimping module 4, the lifting frame 48 first moves on the Z-axis to lift the conveying fixture 323 upward and make it separate from the conveying track 31. Then the vertical axis servo motor module 46 drives the vertical axis frame 44 to move the equipment installed on the vertical axis frame 44 on the Y-axis, that is, towards the terminal crimping machine 41, so that the copper wire on the wire clamping fixture 324 enters the output end of the terminal crimping machine 41 for terminal crimping.

[0041] The terminal crimping machine 41 is also equipped with a terminal strip conveying module 42, which includes a driving guide wheel and a driven guide wheel. One end of the terminal strip is wound around the driven guide wheel, and the other end passes over the driving guide wheel and enters the output end of the terminal crimping machine. When a set of copper wires enters the output end, the terminal crimping machine 41 crimps the copper wires. After crimping a set of copper wires, the longitudinal axis servo motor module 46 drives the longitudinal axis frame 44 to move backward, i.e., away from the terminal crimping machine 41. At the same time, the transverse axis lead screw module 45 drives the transverse axis frame 43 to move to the right, so that the second set of copper wires is aligned with the output end of the terminal crimping machine 41. Then, the longitudinal axis frame 44 moves towards the terminal crimping machine 41, so that the second set of copper wires enters the output end. At the same time, the active working wheel rotates one unit, allowing the new terminal on the terminal strip to advance one unit into the output end, while the waste strip after terminal punching also advances one unit. This cycle repeats until all copper wires have been terminal punched. At this point, the terminal waste strip enters the terminal waste strip recycling module 5. Then, the output end of the terminal waste strip recycling module 5 cuts one unit of waste strip and enters the recycling box to wait for recycling. After the terminal punching is completed, the lifting frame 48 drives the conveying fixture 323 to move downward, and at the same time, the brake cylinder 47 resets and no longer blocks the conveying fixture 323. When the conveying fixture 323 contacts the conveying track 31, it continues to move into the next process.

[0042] refer to Figure 9 and Figure 10The conveyor track 31 in front of the resistance welding module 7 is also equipped with a brake cylinder 47 and a lifting frame 48 to prevent the movement of the conveyor fixture 323. The line adjustment module 2 includes a resistance welding mounting frame 716, which is controlled by a cylinder module to move along its Y-axis. A resistance welding machine 71 is mounted on the resistance welding mounting frame 716. The resistance welding machine 71 includes a lower electrode welder 711 and an upper electrode welder 712 mounted on the resistance welding mounting frame 716. Both the lower electrode welder 711 and the upper electrode welder 712 are controlled to move up and down by a cylinder module. Between the lower electrode welder 711 and the upper electrode welder 712, there is a gripper 715 mounted on the resistance welding mounting frame 716 and controlled to open and close by a servo motor module. The gripper 715 is Y-shaped. The cylinder module controls the resistance welding mounting... The bracket 716 approaches the wire clamping fixture 324, and then the copper wire is clamped by the first clamp 715. The clamping position is located behind the terminal to keep the copper wire stable during welding. Then the lower electrode weld 711 moves upward and contacts the copper wire. The lower electrode weld 711 has a groove that matches the copper wire, and the copper wire is placed in the groove. The upper electrode weld 712 moves downward and passes through the first clamp 715 to contact the lower electrode weld 711. When they contact, electric welding is generated, thus completing the process. After welding one group, the cylinder module resets the resistance welding mounting bracket 716. At the same time, the servo motor module drives the resistance welding mounting bracket 716 to move to the left. Then the cylinder module controls the resistance welding mounting bracket 716 to move forward, using the first clamp 715 to clamp the copper wire. The previous actions are repeated until each group of copper wires is welded.

[0043] like Figure 9 As shown, a waste gas recovery module 72 is provided on one side of the resistance welding mounting bracket 716. The waste gas recovery module 72 includes a recovery pipe 722 and a recovery box 721. The waste gas generated by resistance welding enters the recovery box 721, is purified, and then discharged to the outside through the recovery pipe 722. In addition, a cleaning brush 714 is also installed on the resistance welding mounting bracket 716 via a cylinder module. The cleaning brush 714 has bristles on both the upper and lower sides. The cylinder module controls the cleaning brush 714 to rub back and forth on the lower electrode weld 711 and the upper electrode weld 712, thereby cleaning the weld joint and extending its protection life. In addition, the flexible hose 713 can be bent at will, so that the air outlet of the flexible hose 713 is aligned with the weld joint, thereby achieving rapid cooling.

[0044] After passing through the previous resistance welding module 7, the wires proceed along the independent conveyor track 312 to the next inspection process, namely the vision positioning module 8. The vision positioning module 8 includes an inspection frame equipped with a high-frequency camera and a gripper controlled by a cylinder module. The gripper clamps all the copper wires at once, and then the high-frequency camera takes high-speed pictures and performs inspection. The algorithm software and equipment used by the vision positioning module 8 for comparison inspection are existing technologies, and their working principle will not be described in detail.

[0045] refer to Figure 7 and Figure 8 After passing through the testing process, the heat shrink tubing enters the heat sealing module 9. The copper wire on the wire clamping fixture 324 enters the output end of the hot air gun 95 through the cylinder module. The heat sealing module 9 includes a heat shrink tubing roll 91 mounted on the assembly machine mounting frame 1. In addition, a heat sealing frame is also mounted on the assembly machine mounting frame 1. The heat sealing frame is equipped with multiple distributing rollers 92 and tube feeding rollers 93 arranged vertically. The distributing rollers 92 and tube feeding rollers 93 are controlled to rotate by a servo motor module. The heat sealing frame also has corresponding connecting holes 96. The heat shrink tubing is pulled out from the heat shrink tubing roll 91, passes around the distributing rollers 92, passes between the two tube feeding rollers 93, and then comes out from the connecting hole 96. The cylinder module controls the gripper 2 97 to approach the connecting hole 96 and clamp the heat shrink tubing. A cutter is installed above 6. After being pulled to a suitable length, the cutter cuts the heat shrink tubing. Then, the gripper 97 slowly pulls the heat shrink tubing toward the copper wire and wraps it. Afterward, the Z-axis lifting module 94 controls two hot air guns 95 to move closer to each other and then starts the hot air guns 95 to heat seal the heat shrink tubing onto the copper wire. After completion, the equipment on the heat shrink tubing heat sealing module 9 is reset, waiting for the next heat sealing. The heat-sealed heating pad enters the rear lifting module through the independent conveyor track 312. Then, it is manually removed from the conveyor fixture 323. The empty conveyor fixture 323 is driven downward by the rodless cylinder module 321 in the rear lifting module and enters the front lifting module through the conveyor track 31 in the assembly machine mounting frame 1, realizing a closed loop.

[0046] Through the above process, the equipment for assembling heating pads is centralized and modularized, realizing the automation of material loading and unloading and product assembly. According to CT analysis of each workstation, the time for wire adjustment module 2 is 45s, the total time for terminal crimping module 4 and terminal waste tape recycling module 5 is 25s, the time for copper wire cutting module 6 is 10s, the time for resistance welding module 7 is 25s, the time for vision positioning module 8 is 12s, and the time for heat shrink tubing heat sealing module 9 is 18s. The total time in the manufacturing process is only 135s, and the human-machine ratio is 2:1, thus improving production efficiency and saving labor costs.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
