Description

Technical Field

[0001] This utility model relates to the technical field of tin plating equipment, and more specifically, to a copper wire tin plating equipment for new energy vehicles. Background Technology

[0002] In the production and manufacturing of new energy vehicles, copper wire is an important conductive component, and its performance directly affects the stability and safety of the vehicle's electrical system. Tin plating is a common and effective way to improve the weldability, corrosion resistance and oxidation resistance of copper wire.

[0003] In the existing technology, when replacing copper wires in tin-plating processes, it is usually necessary to remove the tin material from the tin-plating bath before inserting the copper wire into the bottom of the tin-plating bath for replacement, which consumes a lot of time and is difficult to operate.

[0004] Therefore, we have made improvements to this and proposed a copper wire tin plating device for new energy vehicles. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing copper wire tinning devices for new energy vehicles typically require the removal of the tin plating solution from the tin plating tank before the copper wire is inserted into the bottom of the tin plating tank for replacement, which consumes a lot of time and is difficult to operate.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A copper wire tinning device for new energy vehicles is proposed to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] The device includes: a tin plating box; an auxiliary roller; and a winding roller. Two lifting grooves are formed on both the front and rear sides of the inner surface of the tin plating box. A lifting component for controlling the height of the auxiliary roller is slidably connected to the inner surface of each lifting groove. Mounting plates are fixedly connected to both the left and right sides of the outer surface of the tin plating box. A power component for controlling the rotation of the winding roller is rotatably connected to the inner surface of each mounting plate. Mounting plates are fixedly connected to the outer surface of the tin plating box behind the two mounting plates. A device for disassembling and replacing the winding roller is slidably connected to the inner surface of each mounting plate.

[0010] To achieve the above technical solution, the power component drives the winding rollers on both sides to rotate, so that the copper wire passes through the tin plating solution inside the tin plating box for tin plating and is then wound up. The lifting component moves the two auxiliary rollers upward, making it convenient for the user to arrange the copper wire onto the surface of the auxiliary rollers. The replacement component facilitates the replacement and installation of the winding rollers on the two rotating shafts, greatly reducing the difficulty of replacement and shortening the replacement time.

[0011] As a preferred embodiment of the copper wire tinning device for new energy vehicles provided by this utility model, the lifting component includes a lifting frame. Lifting grooves are provided on both the left and right sides of the inner surface of the tinning box. The lifting frame is slidably disposed inside the lifting grooves and lifting grooves. A rotating shaft is rotatably connected to the inner side of the lifting frame. Two auxiliary rollers are provided, each fixedly disposed on the outer surface of the two rotating shafts. An installation groove is provided inside the tinning box on the upper side of each of the two lifting grooves. A motor is fixedly connected to the inner bottom surface of the installation groove. A threaded rod is fixedly connected to the output end of the motor. The threaded rod is rotatably connected to the tinning box and threadedly connected to the lifting frame.

[0012] In a preferred embodiment of the copper wire tin plating device for new energy vehicles provided by this utility model, an auxiliary groove is provided on the outer surface of the auxiliary roller.

[0013] To achieve the above technical solution, the operation of motor one drives the threaded rod to rotate. The rotation of the threaded rod causes the lifting frame, rotating shaft one, and auxiliary rollers to move vertically upward under the limiting action of lifting groove one and lifting groove two. Then, the copper wire passes through the lower surface of the two auxiliary rollers in sequence. Then, motor one works again to drive the threaded rod to rotate in the opposite direction, which can move the auxiliary rollers back into the tin plating solution inside the tin plating box. The auxiliary grooves opened on the outer surface of the auxiliary rollers ensure the stable transmission of the copper wire.

[0014] In a preferred embodiment of the copper wire tinning device for new energy vehicles provided by this utility model, the power component includes two rotating blocks, each rotatably connected to one of two mounting plates. Two rotating rods are rotatably connected to the front side of the tinning box. Synchronous pulleys are fixedly connected to the front ends of both the rotating blocks and the rotating rods. A synchronous belt is meshed between the outer surfaces of the two synchronous pulleys. Synchronous pulleys are fixedly connected to the outer surfaces of both rotating rods. A synchronous belt is meshed between the outer surfaces of the two synchronous pulleys. A mounting frame is fixedly connected to the outer surface of the tinning box below one of the rotating rods. A motor is fixedly connected to the front side of the mounting frame, and the output end of the motor is fixedly connected to one of the rotating rods.

[0015] To achieve the above technical solution, during tin plating, copper wire is wound around the surface of the right winding roller and passes through the lower surfaces of two auxiliary rollers in sequence before being wound around the surface of the left winding roller. The copper wire on the surface of the right winding roller is not tin-plated, while the copper wire on the surface of the left winding roller is already tin-plated. The copper wire inside the tin plating box is located between two stirring rods. Motor 2 drives the rotating rod and synchronous wheel 2 to rotate, and through the action of synchronous belt 2, drives another synchronous wheel 2 and the rotating rod to rotate synchronously, thereby causing the two synchronous wheels 1 to rotate synchronously. Under the action of the two synchronous belts 1, the other two synchronous wheels 1, the rotating block and the rotating shaft 2 rotate, which in turn drives the winding rollers on both sides to rotate, causing the copper wire on the surface of the right winding roller to be released and pass under the two auxiliary rollers for tin plating. Then, it is collected by winding through the rotation of the right winding roller.

[0016] In a preferred embodiment of the copper wire tinning device for new energy vehicles provided by this utility model, the replacement component includes a second rotating shaft, and two second rotating shafts are provided. The two second rotating shafts are slidably connected to two second mounting plates respectively. The two winding rollers are slidably disposed on the outer surfaces of the two second rotating shafts respectively. A slot is provided on the rear side of the rotating block. A locking block is fixedly connected to the front side of the second rotating shaft. The locking block is slidably disposed inside the slot. A connecting plate is rotatably connected to the rear end of the second rotating shaft. A slot is provided on the rear side of the second mounting plate. An insert is fixedly connected to the front side of the connecting plate. The insert is slidably disposed inside the slot.

[0017] In a preferred embodiment of the copper wire tin plating device for new energy vehicles provided by this utility model, the mounting plate two has a mounting groove two inside located on one side of the slot. A spring is fixedly connected to one side of the inner surface of the mounting groove two. A fixing block is fixedly connected to one end of the spring. A fixing groove is opened on the outer surface of the insertion block. The fixing block is slidably arranged inside the mounting groove two and the fixing groove respectively. A connecting rod is fixedly connected to one side of the fixing block. One end of the connecting rod extends to the outside of the mounting plate two and is fixedly connected to a pull plate.

[0018] To achieve the above technical solution, when it is necessary to replace the winding roller, pull the pull plate to disengage the fixing block from the inside of the fixing groove and compress the spring. Then pull the connecting plate to the right to pull out the insert block, the rotating shaft 2, and the locking block from the slot, the winding roller, and the locking groove, respectively. Then the winding roller can be taken out for easy replacement.

[0019] In a preferred embodiment of the copper wire tinning device for new energy vehicles provided by this utility model, two stirring rods are rotatably connected to the inner bottom surface of the tinning box. The lower ends of the two stirring rods extend to the bottom of the tinning box and are fixedly connected to a synchronous wheel three. A synchronous belt three meshes between the outer surfaces of the two synchronous wheels three. A mounting frame two is fixedly connected to the lower surface of the tinning box. A motor three is fixedly connected to the lower surface of the mounting frame two. The output end of the motor three is fixedly connected to one of the stirring rods.

[0020] To achieve the above technical solution, when motor three is working, it drives one of the stirring rods to rotate. Through the transmission of synchronous pulley three and synchronous belt three, the other stirring rod rotates synchronously to stir the tin plating solution in the tin plating box and ensure that the composition of the tin plating solution is uniform.

Mounting plates are fixedly connected to the outer surface of the tinning box behind the two mounting plates. A device for disassembling and replacing the winding rollers is slidably connected to the inner surface of the mounting plates.

[0042] Please refer to Figure 1 and Figure 8The power components include two rotating blocks 31, which are rotatably connected to two mounting plates 3.

Synchronous belts 34 are meshed between the outer surfaces of the two synchronous pulleys 33. Synchronous pulleys 35 are fixedly connected to the outer surfaces of the two rotating rods 32.

A motor 38 is fixedly connected to the front side of the mounting bracket 37. The output end of the motor 38 is fixedly connected to one of the rotating rods 32. Two stirring rods 6 are rotatably connected to the inner bottom surface of the tin plating box 1. The lower ends of the two stirring rods 6 extend to the bottom of the tin plating box 1 and are fixedly connected to a synchronous pulley 63. A synchronous belt 64 meshes between the outer surfaces of the two synchronous pulleys 63. A mounting bracket 61 is fixedly connected to the lower surface of the tin plating box 1. A motor 62 is fixedly connected to the lower surface of the mounting bracket 61. The output end of the motor 62 is fixedly connected to one of the stirring rods 6. During tin plating, motor 362 drives one of the stirring rods 6 to rotate. Through the transmission of synchronous pulley 363 and synchronous belt 364, the other stirring rod 6 rotates synchronously to stir the tin plating solution in the tin plating tank 1, ensuring that the composition of the tin plating solution is uniform. At the same time, motor 238 drives the rotating rod 32 and synchronous pulley 235 to rotate. Through the action of synchronous belt 236, it drives another synchronous pulley 235 and rotating rod 32 to rotate synchronously, thereby causing the two synchronous pulleys 133 to rotate synchronously. Under the action of the two synchronous belts 134, the other two synchronous pulleys 133, rotating block 31 and rotating shaft 241 rotate, which in turn drives the winding rollers 42 on both sides to rotate. The copper wire on the surface of the right winding roller 42 is released and passes under the two auxiliary rollers 24 for tin plating. Then, it is collected by winding through the rotation of the right winding roller 42.

[0043] Specifically, when the winding roller 42 needs to be replaced, pull the pull plate 55 to disengage the fixing block 51 from the inside of the fixing groove 52 and compress the spring 53. Then pull the connecting plate 45 to the right to pull out the insert block 47, the rotating shaft 2 41, and the locking block 44 from the slot 46, the winding roller 42, and the locking groove 43, respectively. Then remove the winding roller 42. Then place the new winding roller 42 between the mounting plate 1 3 and the mounting plate 2 4 for reinstallation. Subsequently, the motor 1 26 drives the threaded rod 27 to rotate. The rotation of the threaded rod 27 drives the lifting frame 22, the rotating shaft 1 23, and the auxiliary roller 24 to move vertically upward under the limiting action of the lifting groove 1 2 and the lifting groove 2 21. Then, the copper wire passes through the lower surface of the two auxiliary rollers 24 in sequence. Then, the motor 1 26 drives the threaded rod 27 to rotate in the opposite direction to move the auxiliary roller 24 back into the tin plating solution inside the tin plating box 1. The auxiliary groove 28 on the surface ensures stable transmission of copper wire. During tin plating, motor 362 drives one of the stirring rods 6 to rotate. Through the transmission of synchronous pulley 363 and synchronous belt 364, the other stirring rod 6 rotates synchronously to stir the tin plating liquid in the tin plating box 1, ensuring uniform composition of the tin plating liquid. At the same time, motor 238 drives the rotating rod 32 and synchronous pulley 235 to rotate. Through the action of synchronous belt 236, it drives another synchronous pulley 235 and rotating rod 32 to rotate synchronously, thereby causing the two synchronous pulleys 133 to rotate synchronously. Under the action of the two synchronous belts 134, the other two synchronous pulleys 133, rotating block 31 and rotating shaft 241 rotate, which in turn drives the winding rollers 42 on both sides to rotate, so that the copper wire on the surface of the right winding roller 42 is released and passes under the two auxiliary rollers 24 for tin plating. Then, it is wound and collected by the rotation of the right winding roller 42.
