[0033] The wire transmission mechanism 20 includes a support plate 21, which is arranged inside the support frame 114 and connected to the side of the conveyor frame 11. The upper surface of the support plate 21 is provided with a first connecting plate 22, and the first rotating shaft 113 is rotatably connected to the first connecting plate 22. The circumferential surface of the first rotating shaft 113 is transmission-connected with a new energy harness disk 23, and the new energy harness disk 23 is located in the middle of the first connecting plate 22.

A wire stripping machine 214 is provided in the middle of the plate 215, and the wire stripping machine 214 is located at the rear side of the first guide roller 29 and the second guide roller 213. A movable slide rail 216 is provided on the upper surface of the support plate 21. The movable slide rail 216 is internally slidably connected to a slider 217. An electric slide rail 218 is provided on the upper surface of the slider 217. The electric slide rail 218 is internally slidably connected to an electric clamp 219. A connecting slide rod 220 is provided on the lower surface of the slider 217, and the connecting slide rod 220 is slidably connected to the support plate 21 and the movable slide rail 216.

[0034] It should be noted that when the first rotating shaft 113 rotates, the new energy wiring harness disc 23 can be driven to rotate to unwind the new energy wiring harness. When the first rotating shaft 113 rotates, the fourth transmission shaft 26 can be driven to rotate under the action of the first gear 24 and the second gear 25. When the fourth transmission shaft 26 rotates, under the action of the third transmission belt 27, the second rotating shaft 28 can be driven to rotate, thereby driving the first guide roller 29 to rotate. The second rotating shaft 28 can drive the third rotating shaft 212 to rotate by the action of the third gear 210 and the fourth gear 211, thereby driving the second guide roller 213 to rotate. Under the action of the first gear 24, the second gear 25, the third gear 210 and the fourth gear 211, the rotation direction of the new energy wiring harness disc 23 is the same as the rotation direction of the second guide roller 213 and is opposite to the direction of the first guide roller 29. Under this condition, the first guide roller 29 cooperates with the second guide roller 213 to transport the new energy wiring harness unwound by the new energy wiring harness disc 23 forward. There is a certain transmission ratio between the first gear 24 and the second gear 25. This transmission ratio can make the new energy wire harness unwound by the new energy wire harness disc 23 exactly the same as the wire harness conveyed by the first guide roller 29 and the second guide roller 213. This function can prevent the new energy wire harness from being piled up and wound between the new energy wire harness disc 23 and the first guide roller 29 and the second guide roller 213. With the cooperation of the first guide roller 29 and the second guide roller 213, the new energy wire harness can be conveyed to the inside of the wire stripping machine 214. The wire stripping machine 214 can strip the front end of the new energy wire harness where spot welding is required. When the new energy wire harness is stripped by the wire stripping machine 214 and comes out to the moving part, the electric clamp 219 will clamp the unstripped part of the new energy wire harness. At the same time, the slider 217 drives the new energy wire harness to be conveyed to the position where the electronic components need to be spot welded under the action of the moving slide rail 216, and then the two are welded using the ultrasonic spot welding equipment 12.

[0035] The reciprocating mechanism 30 includes a connecting bracket 31, which is arranged on the lower surface of the support plate 21, and the lower surface of the connecting bracket 31 is connected to the inner bottom wall of the support frame 114. A gear assembly frame 32 is provided inside the connecting bracket 31, and the internal rotation of the gear assembly frame 32 is connected to a first eccentric gear 33, and the internal rotation of the gear assembly frame 32 is connected to a drive shaft 34, and the drive shaft 34 is transmission-connected to the first eccentric gear 33, and the internal rotation of the gear assembly frame 32 is connected to a second eccentric gear 35, and the second eccentric gear 35 is meshed with the first eccentric gear 33, and the second eccentric gear 35 is hinged to a moving frame 36 through a hinge shaft, and the moving frame 36 is hinged to the moving frame 36. A sliding rod 37 is provided on the side of the frame 36, and the sliding rod 37 is slidably connected to the connecting bracket 31, and the end of the sliding rod 37 away from the movable frame 36 is connected to the connecting sliding rod 220, and the circumferential surface of the first rotating shaft 113 is transmission-connected with the fourth transmission belt 38, and a transmission 39 is provided on the side of the support frame 114, and the end of the fourth transmission belt 38 away from the first rotating shaft 113 is transmission-connected with the input end of the transmission 39, and the output end of the transmission 39 is transmission-connected with the fifth transmission belt 310, and the end of the fifth transmission belt 310 away from the transmission 39 is transmission-connected with the drive shaft 34, and the drive shaft 34 passes through the lower surface of the support frame 114 and is rotationally connected thereto.

[0036] It should be noted that when the first rotating shaft 113 rotates, the fourth transmission belt 38, the transmission 39 and the fifth transmission belt 310 can be used to rotate the driving shaft 34. When the driving shaft 34 rotates, the first eccentric gear 33 can be rotated inside the gear assembly frame 32. The first eccentric gear 33 can drive the second eccentric gear 35 to rotate by meshing with the second eccentric gear 35. The first eccentric gear 33 and the second eccentric gear 35 have the same number of teeth, and the axes of the two are on the same line. When the first eccentric gear 33 rotates, it will also push the gear assembly frame 32 to perform eccentric motion. At this time, theoretically, the gear assembly frame 32 will also drive the moving frame 36 to perform eccentric reciprocating motion, but during the rotation of the second eccentric gear 35 and the first eccentric gear 33 Under the action of opposite directions, the lateral force in the eccentric motion will be offset, so that the movable frame 36 can only perform reciprocating linear motion. When the movable frame 36 performs reciprocating linear remote motion, it will drive the sliding rod 37 to perform reciprocating linear remote motion, wherein the remote motion distance of the sliding rod 37 is the sum of the diameters of the first eccentric gear 33 and the second eccentric gear 35, and the driving shaft 34 rotates one circle, and the sliding rod 37 reciprocates one back and forth. This method can achieve a longer distance of reciprocating remote motion while reducing the volume of the device. When the sliding rod 37 reciprocates, under the action of the connecting slide rod 220, it can drive the slider 217 to reciprocate one back and forth inside the movable slide rail 216, so that the electric clamp 219 can clamp the new energy wiring harness and transport it to the position where the electronic component needs to be spot welded, and then reset it.

[0037] The cutting mechanism 40 includes a connecting slide rail 41, and the connecting slide rail 41 is connected to the support plate 21, the connecting slide rail 41 is internally slidably connected with a sliding tooth plate 42, a connecting rod 43 is provided between the sliding tooth plate 42 and the sliding rod 37, and the connecting rod 43 is slidably connected to the connecting slide rail 41, the upper surface of the sliding tooth plate 42 is meshingly connected with a fifth gear 44, the middle part of the fifth gear 44 is provided with a threaded rod 45, the side of the second connecting plate 215 is provided with a limiting slide rail 46, and the threaded rod 45 is rotatably connected to the limiting slide rail 46, and the cutting mechanism 40 is provided on both sides of the second connecting plate 215, the internal sliding connection of the left limiting slide rail 46 is a cutter 47, and the threaded rod 45 is threadedly connected to the cutter 47, and the internal sliding connection of the right limiting slide rail 46 is a cutting seat 48, and the cutting seat 48 is threadedly connected to the threaded rod 45.

[0038] It should be noted that when the sliding rod 37 moves, the sliding tooth plate 42 can be driven to move in the connecting slide rail 41 under the action of the connecting rod 43. The movement of the sliding tooth plate 42 in the connecting slide rail 41 can drive the fifth gear 44 to rotate. When the fifth gear 44 rotates, the threaded rod 45 can be rotated. When the threaded rod 45 rotates, under the limiting action of the limiting slide rail 46, the cutter 47 and the cutting seat 48 can simultaneously approach the middle part of the second connecting plate 215, and then cut off the new energy wire harness in the middle part, that is, when the electric clamp 219 clamps the new energy wire harness and transports it to the position where the electronic components need to be spot welded, the cutter 47 and the cutting seat 48 can just cut off the new energy wire harness. After welding is completed, the electric clamp 219 will release the new energy wire harness. At this time, under the action of the conveyor belt 15, it will drive the combination of the welded electronic components and the new energy wire harness to move to the unloading place for unloading.

[0039] The working principle and use process of the present invention:

[0040] Step one, by making the servo motor 14 work and under the action of the two conveying rollers 13, the conveyor belt 15 can be used for conveying. The conveyor belt 15 can convey the electronic components to the ultrasonic spot welding equipment 12. At the same time, when the conveying roller 13 rotates, the first transmission shaft 16 can be driven to rotate. When the first transmission shaft 16 rotates, the second transmission shaft 18 can be driven to rotate by the action of the first transmission belt 17. When the second transmission shaft 18 rotates, the first bevel gear 19 can drive the second bevel gear 110 to rotate, and then drive the third transmission shaft 111 to rotate. When the third transmission shaft 111 rotates, the second transmission belt 112 can be used to drive the first rotating shaft 113 to rotate. When the first rotating shaft 113 rotates, it can drive the new energy wiring harness disk 23 to rotate to unwind the new energy wiring harness. When the first rotating shaft 113 rotates, The first gear 24 and the second gear 25 can drive the fourth transmission shaft 26 to rotate. When the fourth transmission shaft 26 rotates, the third transmission belt 27 can drive the second rotating shaft 28 to rotate, thereby driving the first guide roller 29 to rotate. The second rotating shaft 28 can drive the third rotating shaft 212 to rotate by the third gear 210 and the fourth gear 211, thereby driving the second guide roller 213 to rotate. With the cooperation of the first guide roller 29 and the second guide roller 213, the new energy wire harness can be transported to the inside of the wire stripping machine 214. The wire stripping machine 214 can strip the part of the new energy wire harness that needs to be spot welded at the front end. When the new energy wire harness is stripped by the wire stripping machine 214 and comes out to the moving part, the electric clamp 219 will clamp the unstripped part of the new energy wire harness.

[0041] Step 2, when the first rotating shaft 113 rotates, the fourth transmission belt 38, the transmission 39 and the fifth transmission belt 310 can be used to rotate the driving shaft 34. When the driving shaft 34 rotates, the first eccentric gear 33 can rotate inside the gear assembly frame 32. The first eccentric gear 33 can drive the second eccentric gear 35 to rotate by meshing with the second eccentric gear 35. Under the cooperation of the first eccentric gear 33 and the second eccentric gear 35, the moving frame 36 can perform reciprocating linear motion. When the moving frame 36 performs reciprocating linear motion, it will drive the sliding rod 37 to perform reciprocating linear motion. When the sliding rod 37 reciprocates, under the action of the connecting slide rod 220, the slider 217 can be driven to reciprocate inside the moving slide rail 216. Back and forth, the electric clamp 219 can clamp the new energy wiring harness and transport it to the position where the electronic components need to be spot welded, and then the two are welded by the ultrasonic spot welding equipment 12, and reset after the spot welding is completed;

[0042] Step three, when the sliding rod 37 moves, the sliding tooth plate 42 can be driven to move in the connecting slide rail 41 under the action of the connecting rod 43, and the sliding tooth plate 42 can drive the fifth gear 44 to rotate when it moves in the connecting slide rail 41. When the fifth gear 44 rotates, the threaded rod 45 can be rotated. When the threaded rod 45 rotates, under the limiting action of the limiting slide rail 46, the cutter 47 and the cutting seat 48 can simultaneously approach the middle part of the second connecting plate 215, and then cut off the new energy wire harness in the middle part, that is, when the electric clamp 219 clamps the new energy wire harness and transports it to the position where the electronic components need to be spot welded, the cutter 47 and the cutting seat 48 can just cut off the new energy wire harness. After the welding is completed, the electric clamp 219 will release the new energy wire harness. At this time, under the action of the conveyor belt 15, it will drive the combination of the welded electronic components and the new energy wire harness to move to the unloading place for unloading.
