Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a swing electroplating device for processing new energy battery casings.

[0021] Embodiment 1: Please refer to Figures 1-4A swing electroplating device for processing a new energy battery shell comprises a tank body 1, an anode 2 mounted on the side wall of the tank body 1, a beam 3 is arranged above the tank body 1, a pumping and spraying assembly 4 is arranged inside the tank body 1, a hanger 5 for hoisting a workpiece is arranged inside the beam 3, a vertical adjustment assembly 6 is arranged on the top of the beam 3, and the vertical adjustment assembly 6 is used to drive the hanger 5 to move vertically, and a lateral adjustment assembly 7 is also arranged on the hanger 5, and the lateral adjustment assembly 7 is used to drive the workpiece to move horizontally; The pumping and spraying assembly 4 includes a spraying pipe 41 and a nozzle 42 mounted on the spraying pipe 41, wherein the nozzle 42 faces the deep cavity of the workpiece, and the pumping and spraying assembly 4 is used to circulate the solution in the tank body 1 to the deep cavity of the workpiece; Before the electroplating work, the hanger 5 fixes the workpiece, and the vertical adjustment assembly 6 operates to force the workpiece to be immersed in the tank body 1; During electroplating, the pumping and spraying assembly 4 operates to circulate and spray the solution into the deep cavity of the workpiece to achieve forced internal circulation of the solution. At the same time, the vertical adjustment assembly 6 and the horizontal adjustment assembly 7 operate to force the workpiece to perform a composite swinging movement up, down, left and right.

[0022] The tank body 1, the spray pipe 41 and the nozzle 42 are all made of corrosion-resistant materials. The shape of the spray pipe 41 matches the shape of the shell. The number of the nozzles 42 is set according to actual needs. The positions of the nozzles 42 are aligned with the corners in the deep cavity of the shell. When in use, first fix the workpiece by the hanger 5, and then start the vertical adjustment component 6. After the vertical adjustment component 6 is operated, the hanger 5 is driven to move vertically, thereby driving the workpiece to move vertically, and the workpiece is placed in the tank body 1 immersed in the solution. After the tank body 1 is operated, the workpiece is electroplated. At the same time, the pumping and spraying component 4 is operated to continuously spray the solution into the deep cavity of the workpiece, so that the solution contacts the corners in the deep cavity of the workpiece after forced circulation. In addition, the vertical adjustment component 6 and the lateral adjustment component 7 are started. When the vertical adjustment component 6 is operated, it drives the hanger 5 and the workpiece to reciprocate vertically, and when the lateral adjustment component 7 is operated, it drives the hanger 5 and the workpiece to reciprocate horizontally, so that the workpiece performs a compound swinging motion up and down and left and right, further updating the solution in the deep cavity of the shell, avoiding ion depletion by forcing solution circulation and compound swinging, and ensuring that the electroplating inside the deep cavity of the workpiece is more efficient. When the electroplating work is completed, the vertical adjustment component 6 is started again to drive the hanger 5 and the workpiece to move up and out of the tank body 1.

[0023] By setting up the vertical adjustment component 6 and the horizontal adjustment component 7, the workpiece can be driven to move up, down, left and right in the electroplating tank, and then the compound swing mode is adopted to improve the fluidity of the solution, thereby improving the electroplating effect. The effect is better than the ordinary swing mode and is applicable to large shell workpieces. By setting up the pumping and spraying component 4, the solution can be circulated and pumped to the corners inside the deep cavity of the workpiece, and then the forced circulation of the solution is used to ensure that the corners are in contact with the new solution, which can also improve the electroplating effect. Under the action of these two methods, the electroplating quality of the battery shell can be improved.

[0024] Embodiment 2: Refer to Figure 2 , different from the above embodiment, tracks 8 are provided on both sides of the tank body 1. A bracket 9 is fixed at the bottom of the track 8, and the bracket 9 is fixedly connected to the side wall of the tank body 1. A frame 10 is fixed at the bottom end of the cross beam 3, and the frame 10 is slidably connected to both tracks 8.

[0025] Among them, the frame 10 is set as a horizontally arranged rectangular metal frame. During use, after the workpiece is fixed, the frame slides along the track 8 to the upper part of the tank body 1, so that the cross beam 3 moves to the upper part of the tank body 1, and then the vertical adjustment component 6 is started to put the workpiece into the tank body 1. When the electroplating work is completed, the frame is moved again to transfer the workpiece to other workstations.

[0026] Embodiment 3, refer to Figures 3-6 , different from the above embodiment, the sling 5 includes a horizontal slide rail 51. Roller wheels 52 are installed at both ends of the horizontal slide rail 51, and the roller wheels 52 are vertically slidably connected to the cross beam 3. A strip-shaped slider 53 is slidably connected to the horizontal slide rail 51. A suspension rope 54 is fixed to the bottom of the strip-shaped slider 53, and the suspension rope 54 is used to connect the workpiece. The vertical adjustment component 6 includes a main motor 61 and a main rotating shaft 62. The main rotating shaft 62 is rotatably connected to the top end of the cross beam 3, the main motor 61 is fixedly connected to the top end of the cross beam 3, the output shaft of the main motor 61 is fixedly connected to the end of the main rotating shaft 62, a main winding wheel 63 is fixed on the main rotating shaft 62, and a rope belt 64 is fixedly wound on the main winding wheel 63. The bottom end of the rope belt 64 is fixedly connected to the horizontal slide rail 51.

[0027] Wherein, vertical channels matching the rollers 52 are provided inside both sides of the cross beam 3. The lifting ropes 54 are made of metal ropes. A plurality of lifting ropes 54 are provided and are evenly connected to the top edge of the workpiece. During use, the lifting ropes 54 are connected to the top of the workpiece, and then the main motor 61 is started. When the main motor 61 operates, it drives the main rotating shaft 62 to rotate. When the main rotating shaft 62 rotates, it drives the main winding wheel 63 to rotate. When the main winding wheel 63 rotates, it pulls the rope belt 64. The rope belt 64 pulls the horizontal sliding rail 51 upward. When the horizontal sliding rail 51 moves upward, it drives the strip-shaped slider 53 to move upward. When the strip-shaped slider 53 moves upward, it drives the lifting ropes 54 and the workpiece to move upward. Similarly, when the main motor 61 drives the main rotating shaft 62 to rotate in the reverse direction, the workpiece can be driven to move downward; By providing the vertical adjustment assembly 6, the main motor 61 can drive the workpiece to move up and down respectively when rotating forward and backward, which is beneficial to realizing the loading and unloading work of the workpiece during electroplating, and can also drive the workpiece to swing vertically up and down reciprocally during the electroplating process, enabling the ions in the liquid to come into full contact with the workpiece and improving the electroplating effect.

[0028] Example 4, refer to Figure 7 and Figure 8 Differing from the above embodiments, the horizontal adjustment assembly 7 includes a horizontal screw rod 71 and a driving motor 72. The horizontal screw rod 71 passes through the strip-shaped slider 53 and is threadedly connected to the strip-shaped slider 53. Both ends of the horizontal screw rod 71 are rotatably connected to both ends of the horizontal sliding rail 51. A driven bevel gear 73 is fixed on the horizontal screw rod 71. The driving motor 72 is fixed on the horizontal sliding rail 51. A driving bevel gear 74 is fixed on the output shaft of the driving motor 72. The driving bevel gear 74 meshes with the driven bevel gear 73.

[0029] Wherein, the horizontal screw rod 71 is located inside the horizontal sliding rail 51. During use, the driving motor 72 is started. When the driving motor 72 operates, it drives the driving bevel gear 74. When the driving bevel gear 74 rotates, it drives the driven bevel gear 73 to rotate. When the driven bevel gear 73 rotates, it drives the horizontal screw rod 71 to rotate. When the horizontal screw rod 71 rotates, it drives the strip-shaped slider 53 to move along the horizontal sliding rail 51. When the strip-shaped slider 53 moves, it drives the workpiece to move horizontally. Similarly, when the driving motor 72 drives the driving bevel gear 74 to rotate in the reverse direction, it drives the strip-shaped slider 53 and the workpiece to move in the reverse direction.

[0030] By providing the horizontal adjustment assembly 7, during the electroplating process, starting the driving motor 72 can drive the workpiece to move left and right reciprocally, which is beneficial to driving the workpiece to swing left and right, enabling the ions in the liquid to come into full contact with the workpiece and improving the electroplating effect.

[0031] Example 5, refer to Figure 9, different from the above embodiments, the pumping and spraying assembly 4 further includes a water pump 43 fixed outside the tank body 1. The input end of the water pump 43 is fixed to the tank body 1 and communicates with the inside of the tank body 1. A hose 44 is fixed to the output end of the water pump 43. The hose 44 is fixed to the spray pipe 41. A horizontally arranged strip plate 45 is fixedly connected inside the tank body 1. A strip hole 46 is formed in the strip plate 45. A movable plate 47 is slidably connected in the strip hole 46. Two vertical rods 48 are fixed to the spray pipe 41. The vertical rods 48 are movably inserted into the movable plate 47. A end plate 49 is fixed between the tops of the two vertical rods 48. A spring 40 is also sleeved on the two vertical rods 48. Two ends of the spring 40 are respectively fixed to the end plate 49 and the movable plate 47.

[0032] Among them, the input end of the water pump 43 corresponds to the bottom of the inner cavity of the tank body 1 so as to pump the solution at the bottom of the tank body 1 upward. During use, the water pump 43 is started. The water pump 43 sucks the solution at the bottom of the inner cavity of the tank body 1. The solution is transported to the spray pipe 41 through the hose 44 and then sprayed out through the nozzle 42. The solution is sprayed onto the corner of the deep cavity of the workpiece, so that the ions in the solution are in full contact with this place, improving the electroplating effect at this place and avoiding uneven electroplating at local parts inside the deep cavity of the workpiece.

[0033] Embodiment Six, refer to Figure 9 , different from the above embodiments, a transverse cylinder 17 is fixedly connected to the side wall of the tank body 1. The output end of the transverse cylinder 17 extends into the tank body 1 and is fixedly connected to the movable plate 47. A vertical cylinder 11 is fixedly connected to the frame 10. A push plate 12 is fixed to the bottom end of the vertical cylinder 11. The push plate 12 corresponds to the position of the end plate 49.

[0034] Among them, when the vertical adjustment assembly 6 and the horizontal adjustment assembly 7 operate to drive the workpiece to swing up and down and left and right, the relative position between the nozzle 42 and the workpiece changes. To ensure that the nozzle 42 can transport the solution to a specified position in the deep cavity of the workpiece, at this time, the transverse cylinder 17 is started. The transverse cylinder 17 extends to push the movable plate 47, so that the movable plate 47 slides along the strip hole 46. When the movable plate 47 slides, it drives the vertical rod 48 to move, and further drives the spray pipe at the bottom end of the vertical rod 48 to move horizontally, enabling the spray pipe to be synchronized with the swinging workpiece. In addition, the vertical cylinder 11 on the frame 10 is started. When the vertical cylinder 11 extends, it drives the push plate 12 to move vertically downward. When the push rod moves vertically downward, it pushes the end plate 49 to move downward. When the end plate 49 moves downward, it drives the vertical rod 48 to move downward and compresses the spring 40. When the vertical rod 48 moves downward, it drives the spray pipe to move downward. When the vertical cylinder 11 contracts, the elastic force of the spring 40 pushes the end plate 49 to move upward, and then drives the vertical rod 48 and the spray pipe to move upward and reset, which can also control the synchronous movement of the spray pipe and the swinging workpiece; By setting the horizontal cylinder 17, the vertical cylinder 11 and the spring 40, when the workpiece sways up, down, left and right inside the tank body 1, the horizontal cylinder 17, the vertical cylinder 11 and the spring 40 can drive the spray pipe to move up, down, left and right, making it synchronous with the workpiece, ensuring that the solution sprayed from the spray pipe always aims at the corner of the deep cavity of the workpiece, so that the two effects of workpiece swaying and forced circulation can be superimposed, further improving the exchange efficiency of the solution.

[0035] Embodiment Seven. Refer to Figure 10 , which is different from the above embodiment in that the top of the cross beam 3 is further provided with a secondary rotating shaft 13 and a secondary rotating shaft 13. The secondary rotating shaft 13 is parallel to the main rotating shaft 62. Both ends of the secondary rotating shaft 13 are rotatably connected to the cross beam 3. The secondary motor 14 is fixed to the top of the cross beam 3 and the output shaft is fixed to the end of the secondary rotating shaft 13. A secondary winding wheel 15 is fixed on the secondary rotating shaft 13, and a pulling rope 16 is fixedly wound on the secondary winding wheel 15. The pulling rope 16 is used to connect to the bottom end of the workpiece.

[0036] Among them, before electroplating and during the electroplating work, the pulling rope 16 is in the unwinding state and does not affect the movement of the workpiece. When the electroplating work is over, first start the vertical adjustment component 6 to lift the workpiece above the tank body 1. At this time, the workpiece has carried out a large amount of solution. Then start the secondary motor 14. When the secondary motor 14 operates, it drives the secondary rotating shaft 13 to rotate. When the secondary rotating shaft 13 rotates, it drives the secondary winding wheel 15 to rotate. When the secondary winding wheel rotates, it winds up the pulling rope 16. After the pulling rope 16 is wound up, it pulls the bottom end of the workpiece. Since the top end of the workpiece is suspended and the position is fixed, when the pulling rope 16 pulls the bottom end of the workpiece, the workpiece tilts, which can make the workpiece tilt. After the workpiece tilts, the deep cavity faces the tank body 1, which can assist in discharging the solution retained in the deep cavity; By setting the secondary rotating shaft 13, the secondary motor 14, the secondary winding wheel 15 and the secondary rotating shaft 13, after the electroplating work is over, the workpiece can be driven to tilt, so that the solution retained in the workpiece can be quickly discharged back into the tank body 1, which can reduce the loss of the solution, reduce the cost, and also reduce the risk of the solution polluting other metal workpieces and equipment when being transferred with the workpiece.
