[0043] First, in this embodiment, the specific structure of the powder dipping processing station 3 is as follows:

[0044] The powder soaking processing station 3 is composed of a powder soaking box 301 and a dust hood 302. The powder soaking box 301 is installed at the right end of the preheating station 2, and the dust hood 302 is fixedly installed above the powder soaking box 301. A lifting frame 303 is movably installed inside the powder soaking box 301. A lifting mechanism 304 is fixedly installed outside the powder soaking box 301 and above the lifting frame 303. A mounting basket 305 is movably installed inside the lifting frame 303. A mounting basket 305 is fixed inside the lifting frame 303 and outside the mounting basket 305. The conductive busbar body 9 is preheated to about 300°C by the preheating station 2, which is helpful for the adhesion of epoxy resin powder. Then, the conductive busbar body 9 is mounted on the mounting mechanism 8 in the first rail carrier unit 5, and then the mounting mechanism 8 is removed and installed in the installation basket 305, so that the conductive busbar body 9 is mounted in the installation basket 305. Then, the lifting frame 303 is lowered by the lifting mechanism 304, so that the installation basket 305 is immersed in the epoxy resin powder in the powder dipping box 301, and the epoxy resin powder enters the inside of the installation basket 305 through the installation basket 305 and adheres to the outside of the conductive busbar body 9. In this process, the reciprocating mechanism 306 is used to drive the installation basket 305 to move back and forth to avoid the accumulation and agglomeration of powder particles, so that the conductive busbar body 9 is fully in contact with the epoxy resin powder without being excessively attached, thereby avoiding the waste of epoxy resin powder, thereby ensuring the uniformity of the adhesion of the epoxy resin powder. At the same time, when the conductive busbar body 9 after the powder dipping is taken out, the lifting frame 303 is slowly raised by the lifting mechanism 304, and the epoxy resin powder inside the installation basket 305 will leak back into the inside of the powder dipping box 301 as the lifting frame 303 is raised, thereby avoiding excessive powder flying due to excessive movement when the conductive busbar body 9 is taken out from the inside of the installation basket 305. At the same time, the dust cover 302 is externally connected to an industrial vacuum cleaner to suck away the floating powder during operation to avoid the impact on the environment and health.

[0045] Furthermore, the preheating station 2 is composed of multiple groups of first conveyor belts 201 and multiple groups of high-temperature preheating furnaces 202. The multiple groups of first conveyor belts 201 are installed in parallel on the left side of the dust-free workshop 1, and the high-temperature preheating furnace 202 is installed at the right end of the first conveyor belt 201. A product marking conveyor belt 203 is installed inside the dust-free workshop 1 and in front of the first conveyor belt 201 at the front. Before preheating the conductive busbar body 9, the insulation range is marked on the product marking conveyor belt 203 to facilitate the subsequent removal of excess insulation on the conductive busbar body 9. Then, the conductive busbar body 9 is sent to the high-temperature preheating furnace 202 for preheating through the multiple groups of first conveyor belts 201. The conductive busbar body 9 is preheated to about 300°C, which helps the adhesion of the epoxy resin powder.

[0046] Then, the four corners on the front and rear sides of the lifting frame 303 are rotatably connected with moving wheels 307, and the multiple sets of moving wheels 307 are in contact with the inner wall of the powder immersion box 301. When the lifting frame 303 is lifted and lowered by the lifting mechanism 304, the multiple sets of moving wheels 307 roll along the inner wall of the powder immersion box 301, thereby ensuring the movement stability of the lifting frame 303 and avoiding excessive movement during the operation to cause the powder to fly.

[0047] Furthermore, the lifting mechanism 304 includes a support frame 308 fixedly installed on the left side of the powder soaking box 301 and located above the lifting frame 303, and a rope collection frame 309 is fixedly installed on the front end of the support frame 308. The rope collection frame 309 is internally rotatably connected to a rope collection wheel 310, and a pull rope 311 is wound around the outer side of the rope collection wheel 310. The outer side of the rope collection frame 309 is rotatably connected to multiple groups of guide wheels 312, and the pull rope 311 is wound around the outer sides of the multiple groups of guide wheels 312. The end of the pull rope 311 close to the lifting frame 303 is hung on the lifting frame 303 through a connector 313. When controlling the lifting frame 303 to be lifted or lowered, the rope collection wheel 310 is rotated to control the lifting and lowering of the lifting frame 303 by retracting and releasing the pull rope 311, and the pull rope 311 can stably pull the lifting frame 303 through the guide wheel 312.

[0048] Among them, a crank 314 is fixedly installed at the front end of the central axis of the rope collecting wheel 310, and a fixed gear 315 is fixedly connected to the outer side of the crank 314. A block 316 is rotatably connected to the left side of the rope collecting frame 309 and located on the outer side of the fixed gear 315. A spring 317 is fixedly connected between the top of the block 316 and the rope collecting frame 309. The rope collecting wheel 310 is rotated by the crank 314 to lift the lifting frame 303. When the lifting frame 303 is raised, the spring 317 continuously acts on the block 316 to fix the fixed gear 315, thereby preventing the crank 314 from rotating by itself, making it convenient to lift the lifting frame 303 to take and place the conductive busbar body 9, while preventing the lifting frame 303 from suddenly falling and stirring up dust.

[0049] Furthermore, a plurality of hanging rods 318 are fixedly connected to the top of the installation basket 305, and a plurality of through grooves 319 are provided on the left and right sides and the bottom of the installation basket 305. When the conductive busbar body 9 is dipped in powder, after the conductive busbar body 9 is mounted on the mounting mechanism 8, the mounting mechanism 8 can be directly mounted in the installation basket 305 through the hanging rods 318, so that the conductive busbar body 9 can be evenly dipped in powder when hung in the installation basket 305, and the removal and placement of the conductive busbar body 9 is convenient. The epoxy resin powder enters the installation basket 305 through the through grooves 319 and adheres to the outside of the conductive busbar body 9. At the same time, after the powder dipping is completed, the epoxy resin powder in the installation basket 305 will leak back into the powder dipping box 301 as the lifting frame 303 rises, thereby avoiding excessive powder flying due to excessive movement when the conductive busbar body 9 is taken out of the installation basket 305.

[0050] Furthermore, the reciprocating mechanism 306 includes a motor 320 fixedly installed on the top of the lifting frame 303, and the front end of the left side of the lifting frame 303 is rotatably connected to the driving wheel 321, and the motor 320 is connected to the rear end of the central axis of the driving wheel 321 through a pulley group 322. A transmission block 323 is fixedly installed on the top of the left side of the installation basket 305, and a transmission rod 324 is installed between the transmission block 323 and the driving wheel 321. During the powder dipping process of the conductive busbar body 9, the starting motor 320 drives the driving wheel 321 to rotate under the transmission of the pulley group 322, and pulls the transmission block 323 to move back and forth under the transmission of the transmission rod 324, thereby driving the installation basket 305 to reciprocate inside the lifting frame 303, avoiding the accumulation and agglomeration of powder particles, so that the conductive busbar body 9 is fully in contact with the epoxy resin powder without excessive adhesion, avoiding the waste of epoxy resin powder, thereby ensuring the uniformity of epoxy resin powder adhesion.

[0051] Furthermore, movable plates 325 are fixedly installed on the left and right ends of the lifting frame 303, and stabilizing frames 326 are fixedly installed on the left and right sides of the installation basket 305 and on the front and rear ends inside the movable plate 325. A fitting wheel 327 is rotatably connected between the stabilizing frame 326 and the movable plate 325. A limiting plate 328 is fixedly connected inside the lifting frame 303 and behind the transmission block 323. Both ends of the transmission rod 324 are rotatably connected to the transmission block 323 and the driving wheel 321 respectively. When the installation basket 305 moves, the fitting wheel 327 on the stabilizing frame 326 rolls on the movable plate 325, thereby driving the movement stability of the installation basket 305, and the limiting plate 328 is used to limit the movement range.

[0052] Secondly, a rubber cutting part placement area 401 and a finished product placement area 601 are respectively installed behind the product inspection rubber cutting line 4 and the product inspection packaging line 6. Both the product inspection rubber cutting line 4 and the product inspection packaging line 6 are composed of multiple groups of parallel installed second conveyor belts 402. The rubber cutting part placement area 401 is used to place rubber cutting tools for easy access. After the powder dipping is completed, the conductive busbar body 9 is mounted on the first track carrier unit 5 through the mounting mechanism 8 for transportation. After being transported to the position of the product inspection rubber cutting line 4, the conductive busbar body 9 is removed and placed on the second conveyor belt 402 of the product inspection rubber cutting line 4. Excess attached powder is cut off according to the product marking line, and then the processed conductive busbar body 9 is mounted on the second track carrier unit 7. The second track carrier unit 7 transports the conductive busbar body 9 to the inside of the curing and baking furnace 10 to complete the final curing. After the curing is completed, it is transported to the product inspection packaging line 6 to complete the final inspection and packaging. The final finished product is placed in the finished product placement area 601.

[0053] Finally, the mounting mechanism 8 includes a hook 801 mounted on the transport module in the first rail transport unit 5 and the second rail transport unit 7, the bottom of the hook 801 is fixedly connected to a connecting block 802, the bottom end of the connecting block 802 and the outer side of the top of the conductive busbar body 9 are fixedly connected to a collar 803, the outer side of the connecting block 802 and the upper positioning block 804 is slidably connected between the collar 803 and the hook 801, the bottom end of the collar 803 and the inner side of the conductive busbar body 9 are fixedly connected to a bracket 805, and the bottom end of the bracket 805 and the outer side of the conductive busbar body 9 are hinged to a lower positioning hook Plate 806, when hanging the conductive busbar body 9, first remove the hook 801 from the carrier module, then move the entire mounting mechanism 8 to cause the upper positioning block 804 to slide downward, and at the same time, open the lower positioning hook plate 806, then insert the inverted bottom end of the conductive busbar body 9 into the ring 803 and close the lower positioning hook plate 806, and finally, re-align the conductive busbar body 9 and use the upper positioning block 804 and the lower positioning hook plate 806 to position the upper and lower ends of the conductive busbar body 9, which not only facilitates the hanging operation of the conductive busbar body 9, but also ensures its stability after hanging.

[0054] When using the device of the present technical solution, the conductive busbar body 9 is first preheated to about 300°C by the preheating station 2 to facilitate the adhesion of the epoxy resin powder. The conductive busbar body 9 is then mounted on the mounting mechanism 8 in the first rail carrier unit 5. The mounting mechanism 8 is then removed and installed in the installation basket 305, thereby mounting the conductive busbar body 9 in the installation basket 305. The lifting frame 303 is then lowered by the lifting mechanism 304, so that the installation basket 305 is immersed in the epoxy resin powder in the powder immersion box 301. The epoxy resin The powder passes through the installation basket 305 and enters the installation basket 305 to adhere to the outside of the conductive busbar body 9. In this process, the reciprocating mechanism 306 is used to drive the installation basket 305 to move back and forth to avoid the accumulation and agglomeration of powder particles, so that the conductive busbar body 9 is fully in contact with the epoxy resin powder without being excessively attached, thereby avoiding the waste of epoxy resin powder, thereby ensuring the uniformity of the epoxy resin powder adhesion. At the same time, when the conductive busbar body 9 after the powder is taken out, the lifting frame 303 is slowly raised by the lifting mechanism 304, and the epoxy resin powder inside the installation basket 305 is The powder will not leak back into the powder dipping box 301 as the lifting frame 303 rises, thereby preventing excessive powder from flying when the conductive busbar body 9 is taken out from the installation basket 305. At the same time, the dust cover 302 is connected to an industrial vacuum cleaner to suck away the floating powder during the operation. After the powder dipping is completed, the conductive busbar body 9 is mounted on the first track carrier unit 5 through the mounting mechanism 8 for transportation, and then transported to the position of the product inspection and cutting line 4, and then the conductive busbar body 9 is removed and placed on the second conveyor belt 402 of the product inspection and cutting line 4. On the surface, the excess attached powder is cut off according to the product markings, and then the processed conductive busbar body 9 is mounted on the second rail carrier unit 7, and the second rail carrier unit 7 transports the conductive busbar body 9 to the interior of the curing and baking furnace 10 to complete the final curing. After the curing is completed, it is transported to the product inspection and packaging line 6 to complete the final inspection and packaging. The final finished product is placed in the finished product placement area 601. The present invention can avoid the impact of excessive powder flying on the environment and health through design, and at the same time can avoid the waste of epoxy resin powder and ensure the uniformity of epoxy resin powder adhesion.

[0055] The embodiment of the present invention also provides a production process of a conductive busbar, and the specific operation steps are as follows:
