[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 4As shown, this utility model provides a continuous tin plating device for metal connectors, including a support frame 1. A driven plate 5 is rotatably connected to one end of the top of the support frame 1, and a driving plate 6 is rotatably connected to the other end of the top of the support frame 1. The bottom end of the driving plate 6 is coaxially fixedly connected to the output end of the drive unit. The driving plate 6 and the driven plate 5 are connected by transmission through a conveyor belt 7. Several equally spaced fixing parts are fixedly connected to the outer wall of the conveyor belt 7. A vertically arranged telescopic rod 10 is fixedly connected to each fixing part. The telescopic end of the telescopic rod 10 faces downward and is fixedly connected to a clamping mechanism. A tin plating part is fixedly connected to the middle of one side of the support frame 1, and a collection box 4 is fixedly connected to the bottom of the other side of the support frame 1. The collection box 4 is close to the driving plate 6.

[0024] The clamping mechanism can hold the metal connectors that need to be tinned. The drive unit can drive the conveyor belt 7 to rotate continuously through the active disk 6 and the driven disk 5. When the clamping mechanism holding the metal connector moves with the conveyor belt 7 to the top of the tinning section, the corresponding telescopic rod 10 extends, controlling the metal connector to descend to the tinning section for tinning. After tinning, the metal connector continues to move with the conveyor belt 7 to the top of the collection box 4. The clamping mechanism releases, and the metal connector automatically falls into the collection box 4 for collection. The clamping mechanism then picks up the next metal connector to continue tinning. This utility model can realize continuous tinning of metal connectors with high working efficiency.

[0025] The clamping mechanism is further optimized by including a connecting groove 11. The top end of the connecting groove 11 is fixedly connected to the telescopic end of the telescopic rod 10. A sliding cavity 14 is provided inside the connecting groove 11. A first slider 16 and a second slider 17 are slidably arranged inside the sliding cavity 14. The top ends of the first slider 16 and the second slider 17 are in sliding contact with the telescopic end of the telescopic rod 10. A spring 15 is fixedly connected between the side wall of the first slider 16 and the inner side wall of the sliding cavity 14. Another spring 15 is fixedly connected between the side wall of the second slider 17 and the inner side wall of the sliding cavity 14. The first slider 16 and the second slider 17 are magnetically connected by a magnetic attraction part. The bottom ends of the first slider 16 and the bottom ends of the second slider 17 that are far apart from each other are respectively fixedly connected to grippers 12. The two grippers 12 are slidably arranged in the through hole 20 opened in the bottom wall of the sliding cavity 14.

[0026] The scheme is further optimized. The magnetic attraction part includes an electromagnet 18 and a permanent magnet 19. The electromagnet 18 is fixedly embedded in the middle of the side wall of the first slider 16 near the second slider 17, and the permanent magnet 19 is fixedly embedded in the middle of the side wall of the second slider 17 near the first slider 16. The electromagnet 18 and the permanent magnet 19 correspond to each other.

[0027] The first slider 16 and the second slider 17 are made of plastic.

[0028] When it is necessary to clamp the metal connector, the electromagnet 18 is energized and generates magnetism, which creates a magnetic attraction with the permanent magnet 19, causing the first slider 16 and the second slider 17 to come closer and fit together. The two grippers 12 also come closer to each other, completing the clamping of the metal connector. After the metal connector is tinned and moves to the top of the collection box 4, the electromagnet 18 is de-energized and no longer creates a magnetic attraction with the permanent magnet 19. At this time, under the action of the rebound force of the two springs 15, the first slider 16 and the second slider 17 separate, and the metal connector automatically falls into the collection box 4.

[0029] In a further optimized design, pads 13 are fixedly connected to the sidewalls of the two grippers 12 that are close to each other.

[0030] The pad 13 is a rubber block that protects the metal connector and prevents the gripper 12 from damaging it.

[0031] The scheme is further optimized. The tin plating part includes a tray 2, which is horizontally set and fixedly connected to the middle of one side of the support frame 1. A plating tank 3 is fixedly connected to the top of the tray 2, and the plating tank 3 is located below several telescopic rods 10.

[0032] The plating tank 3 is filled with a certain amount of tin solution. The connection method between the metal connector and the external circuit during the tin plating process is existing technology and will not be described in detail.

[0033] The solution is further optimized. The fixing part includes a connecting block 8, which is fixedly connected to the outer wall of the conveyor belt 7. A fixing block 9 is fixedly connected to the middle of the side of the connecting block 8 away from the conveyor belt 7. The fixing block 9 is horizontally set and perpendicular to the connecting block 8. The telescopic rod 10 is fixedly connected to the fixing block 9.

[0034] The scheme is further optimized. The drive unit includes a support plate 21, which is fixedly connected to the inner wall of the support frame 1. A motor 23 is fixedly connected to the top of the support plate 21. The output shaft of the motor 23 is coaxially fixedly connected to the drive disc 6, and the drive disc 6 is in rotational contact with the support plate 21.

[0035] In a further optimized design, a support plate 21 is provided between the active disk 6 and the motor 23. The support plate 21 is fixedly connected to the top of the inner wall of the support frame 1. One end of the driven disk 5 is coaxially fixedly connected to a rotating shaft 22. The other end of the rotating shaft 22 is rotatably connected to the support plate 21. The other end of the support plate 21 is fixedly connected to the top of the inner wall of the support frame 1.

[0036] The working process of this utility model is as follows:

[0037] First, the metal connector to be tinned is fixedly clamped between two grippers 12, and then moves with the conveyor belt 7 to directly above the plating tank 3. At this time, the telescopic rod 10 extends, immersing the clamped metal connector into the molten tin in the plating tank 3 to begin tinning. After tinning is completed, the telescopic rod 10 shortens, causing the metal connector to rise to a height higher than the top of the plating tank 3, and then continues to move with the conveyor belt 7 to directly above the collection box 4. After that, the two grippers 12 release, and the tinned metal connector automatically falls into the collection box 4. The two released grippers 12 then continue to clamp another metal connector for tinning.
