Description

Technical Field

[0001] The present application relates to the technical field of electrophoresis processing, and in particular to a swing mechanism, a swing method and an electrophoresis immersion device for an electrophoresis immersion device. Background Art

[0002] Electrophoresis is a technology that uses the difference in the speed of charged particles moving in an electric field to achieve particle separation. The basic principle is that charged particles will move toward the electrode with the opposite electrical properties under the action of the electric field, thereby achieving the separation of particles with different electrical properties. Currently, this technology is widely used in metal surface treatment. In the prior art, electrophoresis immersion tanks are usually used to perform metal surface treatment. During the process, a treatment solution is introduced into the electrophoresis immersion tank, and after the product is placed in the electrophoresis immersion tank, the electric field force can evenly disperse the coating particles in the treatment solution and make the coating particles evenly adhere to the surface of the object, forming a uniform, high-gloss, corrosion-resistant and anti-oxidation coating with high coating quality.

[0003] However, due to the high concentration of the treatment solution, its fluidity is poor. When facing products with more grooves (such as battery boxes), the treatment solution cannot smoothly enter the grooves, which greatly affects the surface treatment quality of the products. At the same time, since some air will remain in the grooves, after the product enters the immersion tank, the air in the grooves will continue to be discharged outward, causing bubbles to continuously be generated in the treatment solution, which greatly affects the electrophoresis effect of the treatment solution.

The upper end of the immersion tank 1 has a notch 11, and the swing mechanism includes a horizontal support frame 3 suspended on the notch 11, two swing components 4 respectively arranged on both sides of the width direction of the immersion tank 1, and a driving component 5 arranged at one end of the length direction of the immersion tank 1. The sides of the length direction and the width direction of the immersion tank 1 are respectively provided with a rack 6 for installing the swing component 4 and the driving component 5. The projection of the immersion tank 1 on the plane where the support frame 3 is located coincides with the support frame 3, the width of the support frame 3 is greater than the width of the immersion tank 1, and the two swing components 4 are respectively connected to the two sides of the width direction of the support frame 3.

[0034] Each swing assembly 4 includes three swing arms 41 arranged at intervals along the length direction of the support frame 3, and a first matching frame 42 arranged on the frame 6. The swing arms 41 are arranged along the vertical direction. The length direction of the first matching frame 42 is parallel to the length direction of the support frame 3. Three matching seats 43 are arranged on the first matching frame 42 along its own length direction. Each matching seat 43 has a matching surface 44, and the matching surface 44 is inclined upward along the extension direction of the first matching frame 42. The three swing arms 41 correspond to the three matching surfaces 44 one by one. The upper ends of the three swing arms 41 are connected to the support frame 3, and the lower ends are movable ends. The movable ends are in contact with the corresponding matching surfaces 44 and are movable along the inclined direction of the matching surfaces 44.

[0035] The driving assembly 5 is used to drive the six movable ends constituting the two swing assemblies 4 to move back and forth on the corresponding matching surfaces 44 .

[0036] In this way, after the product is placed in the hanger 2, the product is immersed in the immersion tank 1, and the driving component 5 drives the two swing components 4 to move, and the six movable ends constituting the two swing components 4 move back and forth on the corresponding mating surfaces 44, thereby driving the support frame 3 to swing back and forth along the length direction and vertical direction of the immersion tank 1, and then driving the hanger 2 to swing back and forth in the immersion tank 1, and the product contained in the hanger 2 shakes in the immersion tank 1 driven by the hanger 2, thereby stirring the treatment solution and increasing the fluidity of the treatment solution, and the accelerated flow of the treatment solution can smoothly enter the product groove, effectively improving the surface treatment quality of the product; at the same time, the treatment solution entering the product groove can quickly discharge the air in the product groove, avoiding the continuous discharge of air in the groove during the electrophoresis process, resulting in excessive bubbles in the treatment solution, effectively improving the electrophoresis effect of the treatment solution, and further improving the surface treatment quality of the product.

[0037] In this embodiment, the movable end is provided with a first roller 45, the rotation axis of the first roller 45 extends in the horizontal direction and is perpendicular to the length direction of the first matching frame 42, and the three first rollers 45 constituting each swing assembly 4 can respectively roll against the three matching surfaces 44. Among them, the first roller 45 is provided with a first wheel groove 451 around the circumference of the side portion, and the matching seat 43 is provided with a side portion of the matching surface 44 and is relatively engaged with the first wheel groove 451, so that the first roller 45 can be prevented from deflecting during the rolling process. A baffle 49 for blocking the first roller 45 is also provided at the end of the matching surface 44 in the inclined direction.

[0038] During the electrophoresis process, the movable end can roll with the mating surface 44 through the first roller 45, which effectively reduces the friction resistance between the movable end and the mating surface 44 and improves the smoothness of the reciprocating movement of the movable end on the mating surface 44, thereby increasing the swing speed of the hanger 2 to further enhance the fluidity of the treatment solution, improve the electrophoresis effect of the treatment solution, and further improve the surface treatment quality of the product.

[0039] In this embodiment, each swing component 4 also includes a transmission module 46, which includes a transmission frame 461. The length direction of the transmission frame 461 is parallel to the length direction of the support frame 3. The driving component 5 can drive the transmission frame 461 to move along its own length direction. Three transmission seats 462 are arranged on the transmission frame 461 at intervals along its own length direction. The three swing arms 41 correspond to the three transmission seats 462 one by one, and each swing arm 41 is slidable in the corresponding transmission seat 462 along its own axis.

[0040] When the driving component 5 drives the transmission frame 461 to move, the three transmission seats 462 can synchronously push the three rocking arms 41 to move during the movement of the transmission frame 461. The three rocking arms 41 can move laterally with the three transmission seats 462 and move upward under the squeezing of the transmission seats 462, thereby driving the support frame 3 to swing, effectively improving the swing stability of the hanger 2, allowing the treatment solution to flow stably and evenly, effectively improving the electrophoresis effect of the treatment solution, and further improving the surface treatment quality of the product.

The four second rollers 4623 correspond to each other in pairs, and each corresponding two second rollers 4623 are arranged along the length direction of the transmission frame 461 and the two can roll against the two sides of the rocking bar 41. When the transmission seat 462 pushes the rocking bar 41, it can roll with the rocking bar 41 through the second rollers 4623, effectively reducing the friction resistance between the rocking bar 41 and the transmission seat 462, improving the smoothness of the reciprocating movement of the rocking bar 41 in the transmission seat 462, so as to increase the swing speed of the hanger 2, further enhance the fluidity of the treatment solution, improve the electrophoresis effect of the treatment solution, and further improve the surface treatment quality of the product.

During the movement of the transmission seat 462, the limit plates 48 can limit the upward movement of the transmission seat 462 to prevent the transmission seat 462 from excessively moving and causing the movable end to separate from the mating surface 44.

[0044] In this embodiment, the transmission module 46 also includes a second matching frame 463 disposed on the frame 6, the length direction of the second matching frame 463 is parallel to the length direction of the support frame 3, and four guide seats 464 are arranged at intervals on the second matching frame 463 along its own length direction, and the transmission frame 461 can be slidably penetrated in the four guide seats 464 along its own length direction. During the movement of the transmission frame 461, it can be kept on a fixed moving path with the cooperation of the four guide seats 464, effectively avoiding the deviation of the transmission frame 461 during the movement process and causing the hanger 2 to deflect during the swing process, effectively improving the swing stability of the hanger 2, allowing the treatment solution to flow stably and evenly, effectively improving the electrophoresis effect of the treatment solution, and further improving the surface treatment quality of the product.

The extension direction of the rotation axis of the two third rollers 4643 is perpendicular to the length direction of the transmission frame 461. The two third rollers 4643 are arranged up and down and can roll against the upper and lower side parts of the transmission frame 461. The third roller 4643 is provided with a third wheel groove 4644 on the circumferential side, and the side of the transmission frame 461 is relatively fitted with the third wheel groove 4644. In this way, the guide seat 464 can roll with the transmission frame 461 through the third roller 4643, effectively reducing the friction resistance between the transmission frame 461 and the guide seat 464, and improving the smoothness of the reciprocating movement of the transmission frame 461 in the guide seat 464, thereby increasing the swing speed of the hanger 2, so as to further enhance the fluidity of the treatment solution, improve the electrophoresis effect of the treatment solution, and further improve the surface treatment quality of the product.

The end of each driving rod 51 is coaxially connected to a cam 53, and the eccentric end of the cam 53 is hinged with a connecting rod 54. The connecting rod 54 is perpendicular to the driving rod 51, and the ends of the two connecting rods 54 away from their respective cams 53 are coaxially hinged to the two transmission frames 461 constituting the two swinging assemblies 4.

[0047] After starting the dual-axis motor, the two driving rods 51 drive the two transmission frames 461 to move back and forth stably through the cooperation of the two cams 53 and the two connecting rods 54 respectively. The two transmission frames 461 drive the three corresponding rocking arms 41 to move back and forth, which effectively improves the swing stability of the hanger 2, enables the treatment solution to flow stably and evenly, effectively improves the electrophoresis effect of the treatment solution, and further improves the surface treatment quality of the product.
