[0014] A lithium battery steel shell electroplating method, based on the above-mentioned lithium battery steel shell electroplating device, specifically comprises the following steps: S1. Move the anode rod with current flowing into the electroplating solution of the electroplating tank, connect the cathode wire to the rear end of the metal carrier, and place the cylindrical lithium battery steel shell horizontally in the storage hopper; S2, the driving device drives the first rotating shaft to rotate counterclockwise, and the first rotating shaft drives the feeding roller and the turntable to rotate counterclockwise synchronously, and the feeding roller rotates until the feeding trough is at the top, and at this time, the cylindrical lithium battery steel shell at the bottom falls into the feeding trough; S3. After the feeding roller rotates 180 degrees counterclockwise, the feeding trough is located at the bottom, and the cylindrical lithium battery steel shell falls on the upper end of the metal carrier. As the feeding roller continues to rotate 180 degrees counterclockwise, the feeding trough returns to the top. During this process, the turntable rotates 180 degrees counterclockwise, so that the Z-shaped rod at the top drives the moving frame to move downward, and the moving frame drives the rack assembly to move downward. The rack assembly and the driving gear assembly are driven, and as the driving gear assembly and the driven synchronous transmission assembly are driven, the first suspension rope and the second suspension rope are moved downward at the same time; S4, after the first lifting rope moves down, the metal carrier moves down, and after the second lifting rope moves down, the slider moves down, and the slider moves down to the bottom of the slide rail and stops moving, and the metal carrier continues to move down into the electroplating solution of the electroplating tank. During this process, the left end of the connecting rod is fixed, and the right end moves downward. The connecting rod is in an inclined state until the feeding trough returns to the top and stops, and at the same time, the cylindrical lithium battery steel shell falls into the feeding trough; S5, after the feeding roller rotates 180 degrees counterclockwise, the feeding trough returns to the bottom again. During this process, the turntable rotates 180 degrees counterclockwise, so that the Z-shaped rod at the bottom drives the moving frame to move upward, and the moving frame drives the rack assembly to move upward. The rack assembly and the driving gear assembly are driven by the driven synchronous transmission assembly, and the first suspension rope and the second suspension rope are moved upward at the same time; S6. After the first lifting rope moves up, the metal carrier moves up, and after the second lifting rope moves down, the slider moves up until the metal carrier moves into the notch, and the cylindrical lithium battery steel shell on the metal carrier pushes the cylindrical lithium battery steel shell in the feed trough and enters the feed trough, while the cylindrical lithium battery steel shell that has not been electroplated above pushes the arc seat into the storage slot and squeezes the spring damper; S7. After the feeding roller turns counterclockwise at an angle of forty-five degrees, the electroplated cylindrical lithium battery steel shell corresponds to the discharge window and falls out of the discharge window, completing the electroplating of the cylindrical lithium battery steel shell.

[0015] Beneficial effect: the cylindrical lithium battery steel shells are stored horizontally in the storage hopper, so that the cylindrical lithium battery steel shells at the bottom fall into the feeding trough, so that after the feeding roller rotates 180 degrees counterclockwise, the feeding trough is at the bottom, and the cylindrical lithium battery steel shell falls on the upper end of the metal carrier, as the feeding roller continues to rotate 180 degrees counterclockwise, the feeding trough returns to the top, and the metal carrier automatically moves down into the electroplating solution of the electroplating tank for electroplating. At the same time, the unplated cylindrical lithium battery steel shells fall into the feeding trough, and after the feeding roller rotates 180 degrees counterclockwise again, the feeding trough returns to the bottom. In this process, the metal carrier automatically moves up into the notch, so that It can complete automatic downward discharge plating and automatic upward movement after electroplating, which is conducive to realizing automated operation. In addition, when the metal carrier drives the electroplated cylindrical lithium battery steel into the feed trough, the cylindrical lithium battery steel shell in the feed trough can be pushed and enter the feed trough, while the cylindrical lithium battery steel shell that has not been electroplated above pushes the arc seat into the storage slot and squeezes the spring damper. Finally, after the feed roller turns counterclockwise at an angle of forty-five degrees, the electroplated cylindrical lithium battery steel shell corresponds to the discharge window and falls out of the discharge window, completing the electroplating of the cylindrical lithium battery steel shell. In this way, the collection of the electroplated cylindrical lithium battery steel shell is also convenient for automation, thereby reducing labor and improving automated production.

A driving device fixed to the cylinder shell 4 is installed at the rear of the first rotating shaft 10, and the driving device includes a worm gear reducer 8 and a motor 9. The worm gear reducer 8 is fixed to the cylinder shell 4, and the output shaft of the worm gear reducer 8 is fixed to the rear of the first rotating shaft 10. The motor 9 is installed on the surface of the worm gear reducer 8, and the output shaft of the motor 9 is fixed to the input shaft of the worm gear reducer 8. The storage hopper 5 stores The cylindrical lithium battery steel shell is horizontally arranged, and the motor 9 is externally connected to a power supply and a switch. After the motor 9 is started, it will transmit with the worm gear reducer 8 to make the output shaft of the worm gear reducer 8 drive the first rotating shaft 10 to rotate counterclockwise, and the first rotating shaft 10 will drive the feed roller 40 to rotate counterclockwise. A feed trough 41 is opened on the surface of the feed roller 40, and a receiving groove 44 at the bottom of the feed trough 41 facilitates the arc seat 43 to move in, and the notch width of the receiving groove 44 is greater than the outer diameter of the cylindrical lithium battery steel shell. When When the feed roller 40 rotates until the feed trough 41 is located above, the lowest cylindrical lithium battery steel shell falls into the feed trough 41 from the upper opening of the cylinder shell 4, but cannot rely on the weight of the upper cylindrical lithium battery steel shell to press down the arc seat 43 until it moves into the storage groove 44 to squeeze the spring damper 45. In this way, as the feed roller 40 rotates counterclockwise until the feed trough 41 no longer corresponds to the upper opening of the cylinder shell 4, the lowest cylindrical lithium battery steel shell in the storage hopper 5 is blocked by the feed roller 40 in the upper opening of the cylinder shell 4.

[0019] A turntable 11 is fixed at the front end of the first rotating shaft 10, and a Z-shaped rod 12 is fixed to one side of the front end of the turntable 11. A movable sleeve is provided on the outer end of the Z-shaped rod 12 with a moving frame 13 in a horizontal state. A rack assembly is connected to the right side of the moving frame 13, and the rack assembly includes a rack 14 and a guide rail 15. The rack 14 is fixed to the moving frame 13, and the guide rail 15 is slidably connected to the right side of the rack 14. The guide rail 15 is fixedly connected to the cylinder shell 4. The counterclockwise rotation of the first rotating shaft 10 will also drive the turntable 11 to rotate synchronously, and the turntable 11 will drive the Z-shaped rod 12 to perform counterclockwise circular motion, and the Z-shaped rod 12 will drive the moving frame 13 to move, but the Z-shaped rod 12 will move horizontally along the moving frame 13 when it performs circular motion. Therefore, the moving frame 13 is vertically downward at this time, and the moving frame 13 drives the rack 14 to move downward along the guide rail 15. The setting of the guide rail 15 is conducive to the limiting of the rack 14, preventing the rack 14 from rotating, so that the rack 14 and the moving frame 13 can only move vertically.

[0020] The lower side of the rack assembly is transmission-connected with a driving gear assembly located at the lower right side of the turntable 11. The driving gear assembly includes a second rotating shaft 16 and a driving large gear 17. The second rotating shaft 16 is connected to the cylindrical shell 4 bearing, and the driving large gear 17 is fixed to the outside of the second rotating shaft 16. The driving large gear 17 is meshed and connected with the rack 14. When the rack 14 moves downward, it can drive the driving large gear 17 to rotate clockwise through the second rotating shaft 16.

[0021] A first suspension rope assembly is fixed at the front end of the cylinder shell 4 and is located directly below the turntable 11. A second suspension rope assembly is fixed at the front end of the cylinder shell 4 and is located directly to the left of the turntable 11. A driven synchronous transmission assembly is installed between the front parts of the first suspension rope assembly and the second suspension rope assembly. The driven synchronous transmission assembly is transmission-connected to the driving gear assembly. The driven synchronous transmission assembly includes a driven pinion 20, a driving synchronous wheel 28, a driven synchronous wheel 29 and a synchronous belt 31. The driving synchronous wheel 28 is rotationally connected to the front of the first suspension rope assembly, and the driven synchronous wheel 29 is rotationally connected to the front of the second suspension rope assembly. The synchronous belt 31 is connected between the active synchronous wheel 28 and the driven synchronous wheel 29. The driven pinion 20 is fixed at the front end of the active synchronous wheel 28. The driven pinion 20 is meshed with the active large gear 17. The first hanging rope assembly includes a first winding box 18, a first shaft 19 and a first hanging rope 21. The first winding box 18 is fixed to the cylinder shell 4. The first shaft 19 is connected to the inside of the first winding box 18 by a bearing. The first winding wheel is fixed to the outside of the first shaft 19. The first hanging rope 21 is wound around the outside of the first winding wheel. The end of the first hanging rope 21 moves through The first winding box 18 has a lower end, and the front end of the first shaft 19 passes through the first winding box 18 and is fixed to the active synchronous wheel 28 and the driven pinion 20. The second rope assembly includes a second winding box 26, a second shaft 27 and a second rope 30. The second winding box 26 is fixed to the cylinder shell 4. The second shaft 27 is connected to the inside of the second winding box 26 by a bearing. A second winding wheel is fixed to the outside of the second shaft 27. The second rope 30 is wound around the outside of the second winding wheel. The end of the second rope 30 movably passes through the left end of the second winding box 26. The front end of the second shaft 27 passes through the The second winding box 26 is fixed to the driven synchronous wheel 29. When the driving large gear 17 rotates clockwise, it meshes with the driven small gear 20, so that the driven small gear 20 drives the first shaft 19 to rotate counterclockwise, and the first shaft 19 drives the driving synchronous wheel 28 to rotate counterclockwise. Because the driving synchronous wheel 28 and the driven synchronous wheel 29 rotate synchronously through the synchronous belt 31, the driven synchronous wheel 29 will drive the second shaft 27 to rotate counterclockwise, so that the first winding wheel unwinds the first suspension rope 21, and the second winding wheel unwinds the second suspension rope 30.

[0022] A notch 22 is provided at the lower end of the cylinder shell 4, a metal carrier 23 is provided inside the notch 22, a loading groove 37 is provided at the upper end of the metal carrier 23, a first hanging rope assembly is connected to the upper side of the front end of the metal carrier 23, an end of the first hanging rope 21 is fixed to the front end of the metal carrier 23, a slide rail 33 is fixed to the front end of the bracket 3, a slider 34 is slidably connected inside the slide rail 33, an upper end of the slider 34 is connected to the second hanging rope assembly, an end of the second hanging rope 30 is fixed to the upper end of the slider 34, a guide wheel 32 is rotatably connected to the upper end of the front end of the bracket 3, the second hanging rope 30 passes over the upper end of the guide wheel 32, a connecting rod 24 is rotatably connected between the front end of the slider 34 and the front end of the metal carrier 23, a first T-shaped shaft 25 is fixed to the center of the front end of the metal carrier 23, a second T-shaped shaft 36 is fixed to the center of the front end of the slider 34, and a connecting rod 24 is rotatably connected to the upper end of the slider 34. The rod 24 runs between the first T-shaped shaft 25 and the second T-shaped shaft 26. A boss 35 is fixed to the front end of the slider 34 and located above the connecting rod 24. Because when the feeding trough 41 rotates to the bottom with the cylindrical lithium battery steel shell, the cylindrical lithium battery steel shell will fall into the loading slot 37 of the metal carrier 23. The loading slot 37 can prevent the cylindrical lithium battery steel shell from falling from above the metal carrier 23. Therefore, when the first hanging rope 21 and the second hanging rope 30 are both unwound, the first hanging rope 21 lowers the metal carrier 23, and the second hanging rope 30 lowers the slider 34. At this time, the slider 34 and the metal carrier 23 move down at the same height at the same time, and the connecting rod 24 also moves down horizontally. At this time, the connecting rod 24 can prevent the rear end of the metal carrier 23 from tilting downward, so that even if one hanging rope hangs the metal carrier 23, the metal carrier 23 can be lifted. At the front end of the carrier 23, the metal carrier 23 can also remain horizontal, and the first hanging rope 21 hangs the top of the metal carrier 23, which can prevent the metal carrier 23 and the connecting rod 24 from rotating and tilting, thereby playing a complementary role, until the slider 34 moves down to the bottom of the slide rail 33, although the second hanging rope 30 is still unwinding, the slider 34 no longer moves down, and the first hanging rope 21 is also still unwinding, but the metal carrier 23 will continue to move into the electroplating solution of the electroplating tank 1. During this process, the left end of the connecting rod 24 is fixed, but the right end tilts and moves downward. At this time, the metal carrier 23 can rotate with the right end of the connecting rod 24 to keep it horizontal, preventing the cylindrical lithium battery steel shell in the metal carrier 23 from falling into the electroplating tank 1, so it does not hinder the downward movement of the metal carrier 23 until the turntable 11 rotates 180 degrees After the angle is adjusted, the Z-shaped rod 12 is located at the bottom. Because the electroplating tank 1 places the energized anode rod, and the metal carrier 23 is connected to the cathode wire, the metal carrier 23 causes the current to flow into the cylindrical lithium battery steel shell to perform the electroplating process. However, at this time, the feed trough 41 is located at the top, and the bottom cylindrical lithium battery steel shell falls into the feed trough 41 from the upper opening of the cylinder shell 4. Then, when the turntable 11 continues to rotate 180 degrees, the Z-shaped rod 12 moves from bottom to top, thereby driving the moving frame 13 to move vertically upward. The moving frame 13 drives the rack 14 to move upward along the guide rail 15, which can drive the active large gear 17 to rotate counterclockwise through the second rotating shaft 16, and then engage with the driven small gear 20, so that the driven small gear 20 drives the first shaft 19 to rotate clockwise.The first shaft 19 drives the active synchronous wheel 28 to rotate clockwise. Because the active synchronous wheel 28 and the driven synchronous wheel 29 rotate synchronously through the synchronous belt 31, the driven synchronous wheel 29 drives the second shaft 27 to rotate clockwise, so that the first winding wheel winds up the first suspension rope 21, and the second winding wheel winds up the second suspension rope 30. When the first suspension rope 21 and the second suspension rope 30 are both wound up, the first suspension rope 21 pulls up the metal carrier 23 until the slider 34 and the metal carrier 23 are at the same height, and the second suspension rope 30 will pull up the slider 34. At this time, the connecting rod 24 is horizontal, and the setting of the boss 35 can block the upper side of the left end of the connecting rod 24 to prevent the right end of the connecting rod 24 from tilting upward when the connecting rod 24 is in a horizontal state, until the metal carrier 23 moves up to the notch 22, and at this time the feed trough 41 is located below, and the electroplated cylindrical lithium battery steel shell in the metal carrier 23 pushes the un-electroplated cylindrical lithium battery steel shell in the feed trough 41 upward, and pushes the un-electroplated cylindrical lithium battery steel shell into the storage groove 44, at this time the arc seat 43 squeezes the spring damper 45, and at this time the feed trough 41 can accommodate two cylindrical lithium battery steel shells.

[0023] Side blocks 38 are fixed at both ends of the slider 34. Balls 39 are rollingly connected to the surfaces of the side blocks 38. The balls 39 are rollingly connected to the slide rails 33. When the slider 34 moves up and down, the balls 39 roll with the slide rails 33, which helps to reduce the sliding friction between the slider 34 and the slide rails 33.

[0024] A discharge window 42 is provided at the lower right end of the cylinder shell 4, an inclined plate 6 is fixed between the lower right end of the cylinder shell 4 and the right side of the upper end of the electroplating tank 1, and a liquid-absorbing cotton 7 is fixed at the upper end of the inclined plate 6, and the liquid-absorbing cotton 7 is located below the discharge window 42. When the feed roller 40 continues to rotate counterclockwise at an angle of forty-five degrees, the electroplated cylindrical lithium battery steel shell corresponds to the discharge window 42. At this time, the spring damper 45 is reset to slowly push the electroplated cylindrical lithium battery steel shell out of the discharge window 42 to complete the electroplating of the cylindrical lithium battery steel shell, and the cylindrical lithium battery steel shell that is moved out of the discharge window 42 falls on the inclined plate 6 and rolls down and is collected. During the rolling process of the cylindrical lithium battery steel shell, the liquid-absorbing cotton 7 can absorb the plating liquid remaining on the surface of the cylindrical lithium battery steel shell.

As the feeding roller 40 continues to rotate 180 degrees counterclockwise, the feeding trough 41 returns to the top. During this process, the turntable 11 rotates 180 degrees counterclockwise, so that the Z-shaped rod 12 at the top drives the moving frame 13 to move downward, and the moving frame 13 drives the rack assembly to move downward, and the rack assembly and the driving gear assembly are driven. As the driving gear assembly and the driven synchronous transmission assembly are driven, the first suspension rope 21 and the second suspension rope 30 are moved downward at the same time; S4, after the first suspension rope 21 moves down, the metal carrier 23 moves down, and after the second suspension rope 30 moves down, the slider 34 moves down, and the slider 34 moves down to the bottom of the slide rail 33 and stops moving, and the metal carrier 23 continues to move down into the electroplating solution of the electroplating tank 1. During this process, the left end of the connecting rod 24 is fixed, and the right end moves downward. The connecting rod 24 is in an inclined state until the feeding trough 41 returns to the top and stops, and at the same time, the cylindrical lithium battery steel shell falls into the feeding trough 41; S5, after the feeding roller 40 rotates counterclockwise by 180 degrees, the feeding trough 41 returns to the bottom again. During this process, the turntable 11 rotates counterclockwise by 180 degrees, so that the Z-shaped rod 12 at the bottom drives the moving frame 13 to move upward, and the moving frame 13 drives the rack assembly to move upward, and the rack assembly and the driving gear assembly are driven. As the driving gear assembly and the driven synchronous transmission assembly are driven, the first suspension rope 21 and the second suspension rope 30 are moved upward at the same time; S6, after the first suspension rope 21 moves up, the metal carrier 23 moves up, and after the second suspension rope 30 moves down, the slider 34 moves up until the metal carrier 23 moves up into the notch 22, and the cylindrical lithium battery steel shell on the metal carrier 23 pushes the cylindrical lithium battery steel shell in the feed trough 41 and enters the feed trough 41, while the cylindrical lithium battery steel shell that has not been electroplated pushes the arc seat 43 to move into the storage groove 44 and squeezes the spring damper 45; S7, after the feeding roller 40 rotates counterclockwise at an angle of 45 degrees, the electroplated cylindrical lithium battery steel shell corresponds to the discharge window 42 and falls out of the discharge window 42, completing the electroplating of the cylindrical lithium battery steel shell.

[0026] In summary, the storage hopper 5 stores horizontally arranged cylindrical lithium battery steel shells, so that the cylindrical lithium battery steel shell at the bottom falls into the feed trough 41, so that after the feed roller 40 rotates counterclockwise by 180 degrees, the feed trough 41 is located at the bottom, and the cylindrical lithium battery steel shell falls on the upper end of the metal carrier 23. As the feed roller 40 continues to rotate counterclockwise by 180 degrees, the feed trough 41 returns to the top, and the metal carrier 23 automatically moves down into the electroplating solution of the electroplating tank 1 for electroplating. At the same time, the unplated cylindrical lithium battery steel shell falls into the feed trough 41. After the feed roller 40 rotates counterclockwise by 180 degrees again, the feed trough 41 returns to the bottom. In this process, the metal carrier 23 automatically moves up into the notch 22. In this way, automatic downward discharge plating and automatic upward movement after electroplating can be completed, which is conducive to realizing automated operation. In addition, when the metal carrier 23 drives the electroplated cylindrical lithium battery steel into the feed trough 41, the cylindrical lithium battery steel shell in the feed trough 41 can be pushed and enter the feed trough 41, while the cylindrical lithium battery steel shell that has not been electroplated above pushes the arc seat 43 to move into the storage slot 44 and squeezes the spring damper 45. Finally, after the feed roller 40 rotates counterclockwise at an angle of forty-five degrees, the electroplated cylindrical lithium battery steel shell corresponds to the discharge window 42 and falls out of the discharge window 42, completing the electroplating of the cylindrical lithium battery steel shell. In this way, the collection of the electroplated cylindrical lithium battery steel shell is also convenient for automation, thereby reducing labor and improving automated production.
