Description

Technical Field

[0001] The utility model relates to the technical field of battery clamp roller plating, in particular to a battery clamp roller plating device. Background Art

[0002] A battery clamp is a tool used to connect batteries to circuits. It usually consists of two metal clips, each with a curved portion, that are used to clamp the positive and negative terminals of the battery. The other end of the clip is usually connected to the circuit to transfer the battery's energy to other devices or systems.

[0003] At present, when the battery clip is produced, the staff first makes the required model through the sand mold. After the model is formed, the staff uses the pouring method to inject slurry into the sand mold. After it cools, it will form the shape of the battery clip. Its shape is as follows Fig. 9 and Fig.10 At this time, the staff will take out the battery clips together with the waste, clean them after taking them out, and then put the waste and battery clips into the electroplating tank through the conveyor device for electroplating. After electroplating, the waste and battery clips are separated, and the production of battery clips can be realized.

[0004] Because, when the above-mentioned battery clamp is cast, in order to facilitate the subsequent disassembly, the connection between it and the waste material is connected in an easy-to-break manner. When the later conveying device drives the battery clamp and the waste material to be electroplated in the electroplating tank, it is necessary to convey them to different electroplating tanks through the conveying device. In the process of conveying, it is easy for the battery clamp and the conveying device to collide with each other. When they collide, it is easy for the connection between the battery clamp and the waste material to break, resulting in the separation of the battery clamp and the waste material, causing the battery clamp to fall into the electroplating tank, and needing to be salvaged by the staff later.

[0005] Therefore, there is a need for a battery clip roller plating device for improving the quality of products. Utility Model Content

[0045] Embodiment 3

[0046] like Figure 1-Figure 8 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0047] A heating wire 9 is fixedly connected to the bottom of the inner cavity of the electroplating pool 2, a first L-shaped slide 10 is symmetrically fixedly connected to one side of the inner cavity wall of the electroplating pool 2, an anode plate 11 is slidably connected to one side of the first L-shaped slide 10 and located between the inner walls of the electroplating pool 2, a second L-shaped slide 12 is symmetrically fixedly connected to the other side of the inner cavity wall of the electroplating pool 2, and a cathode plate 13 is slidably connected to one side of the second L-shaped slide 12 and located between the inner walls of the electroplating pool 2.

[0049] The cooperation between the first L-shaped slideway 10 and the second L-shaped slideway 12 facilitates the replacement of the anode plate 11 and the cathode plate 13 and fixation thereof.

[0050] The working principle and use process of this utility model:

[0051] In use:

[0052] When in use, first, put the battery clip to be electroplated into the diamond-shaped barrel 73 from the material port 75. After putting it in, at this time, place the blocking plate 76 at the material port 75. Before placing it, move the pull rod 79 first, the pull rod 79 drives the locking rod 78 to move, and stretch the reset spring 710. When the locking rod 78 moves to the specified position, at this time, the blocking plate 76 is just placed at the material port 75. At this time, release the pull rod 79, so that the locking rod 78 is reset under the action of the reset spring 710. After resetting, at this time, one end of the locking rod 78 will be inserted into the diamond-shaped barrel 73, so that the diamond-shaped barrel 73 is in a sealed state;

[0053] At this time, the staff moves the gantry 4, and when the gantry 4 moves, it will drive the hydraulic rod 5, the hanging hook 6 and the roller plating assembly 7 to move as a whole. When the roller plating assembly 7 moves to the upper part of the electroplating tank 2, the hydraulic rod 5 is started. The hydraulic rod 5 will drive the hanging hook 6, the roller plating assembly 7 and the inclined block 15 to move downward. When the inclined block 15 moves downward, it will contact one side of the moving plate 88 and squeeze one side of the moving plate 88. At this time, the moving plate 88 squeezes the damping rod 87 and the rotating rod 85, so that the rotating rod 85 retracts into the flower groove 84. When the limit stop in the roller plating assembly 7 When the rod 717 moves downward between the two groups of blocks 14, the movement of the hydraulic rod 5 will be stopped. When the limit rod 717 is located in the block 14, one end of the suspension hook 6 will also move out of the U-shaped block 716. After moving out, the gantry 4 will move forward. When the gantry 4 moves forward, the inclined block 15 will be separated from the moving plate 88. The moving plate 88 will drive the square block 86 to move into the square groove 714 under the action of the damping rod 87, so that the rotating rod 713 is connected with the rotating rod 85. At the same time, the gantry 4 will be separated from the roller plating assembly 7.

[0054] After separation, at this time, the driving motor 82 is started. When the driving motor 82 is working, it will drive the driving rod 83, the rotating rod 85, and the square block 86 to rotate. When the square block 86 rotates, it will drive the rotating rod 713 to rotate. When the rotating rod 713 rotates, it will drive the small gear 715 to rotate. When the small gear 715 rotates, it will drive the large toothed disc 72 to rotate. When the large toothed disc 72 rotates, it will drive the diamond-shaped cylinder 73 to rotate. When the diamond-shaped cylinder 73 rotates, it starts to drive the battery clamp in the diamond-shaped cylinder 73 to flip. When the battery clamp is flipping, it will be blocked by the shattering frame 712. When the battery clamp contacts the shattering frame 712, the battery clamp can be broken up to prevent the battery clamp from being attached, resulting in a poor electroplating effect.

[0055] When the electroplating is completed, the gantry 4 is moved. When the gantry 4 moves, the movable plate 88 will be squeezed by the inclined block 15, and the hanging hook 6 will be moved to the lower part of the U-shaped block 716, so that the roller plating assembly 7 can be taken out of the electroplating tank 2 as a whole, and then put into the next electroplating tank for electroplating. After electroplating, the blocking plate 76 will be opened to take out the battery clamp in the diamond cylinder 73.
