[0041] The battery mainly consists of a top cover, an aluminum shell and a winding core. The top cover and the shell are laser welded into a sealed whole. After the coding process is completed, the pole faces downward, and the top cover needs to be clamped and flipped over and moved to the welding jig. The traditional clamping mechanism mainly uses a servo motor or a cylinder with a secondary rail for lifting and lowering. The clamping claw cylinder clamps the top cover, but in the clamping process, the top cover is easily clamped obliquely or offset, resulting in the transfer clamp clamping the top cover cannot be accurately placed in the welding jig.
[0042] The utility model provides a clamping mechanism.
[0043] See also Figure 1 In one embodiment of the utility model, the clamping mechanism includes:
[0044] Bracket 100;
[0045] A clamping structure 200 is disposed on the support 100 and is used to clamp a target product; and
[0046] The limiting reference member 300 is disposed on the clamping structure 200 to abut against the target product when the clamping structure 200 clamps the target product so that the target product remains in a horizontal state.
[0047] The technical solution of the utility model provides a bracket 100, a clamping structure 200 and a limit reference part 300. The clamping structure 200 clamps the target product and drives the target product to be transferred to the next process. The limit reference part 300 is arranged on the clamping structure 200. When clamping the target product, the clamping structure 200 clamps both ends of the target product, and the limit reference part 300 abuts against the surface of one side of the target product close to the clamping structure 200, so that the target product can always maintain a horizontal state when being clamped, avoiding deformation and deflection of the target product when clamping, thereby improving the stability of the transfer.
[0048] In the specific implementation process, after the top cover of the battery is coded with the pole, the clamping structure 200 needs to clamp the top cover and transfer it to the welding jig. The clamping structure 200 clamps the two ends of the top cover and abuts against the top cover through the limiting reference part 300 to prevent the clamping from being tilted or offset, so that the top cover can be accurately placed in the welding jig.

The connecting plate 310 is arranged on the clamping structure 200. The first limit portion 320 and the second limit portion 330 are arranged on opposite sides of the connecting plate 310 and extend in a direction away from the bracket 100, so that when the clamping structure 200 clamps the target product, the connecting plate 310 abuts against the top surface of the target product, and the first limit portion 320 and the second limit portion 330 abut against the opposite sides of the target product to limit the target product.
[0050] Specifically, the limit reference member 300 includes a connecting plate 310, a first limit portion 320 and a second limit portion 330. The connecting plate 310 is fixed on the side of the clamping structure 200 facing the target product. The first limit portion 320 and the second limit portion 330 are respectively located on both sides of the connecting plate 310 and extend in a direction away from the bracket 100. The gap between the first limit portion 320 and the second limit portion 330 is for the target product to pass through. When the clamping structure 200 clamps the target product, the connecting plate 310 abuts against one side of the surface of the target product, and the first limit portion 320 and the second limit portion 330 abut against the two opposite side surfaces of the target product to limit the target product and prevent the target product from being skewed during the clamping process.

[0052] In detail, the rotating component 400 is arranged on the bracket 100 to drive the clamping structure 200 to rotate on the bracket 100 to flip the target product. In the specific implementation process, after the pole coding of the top cover is completed, the pole side of the top cover is set to face upward, and the pole side of the top cover in the welding fixture is required to face downward. The clamping structure 200 is driven to rotate by the rotating component 400, so that the clamping structure 200 and the top cover are flipped together to achieve actual needs.

[0057] In detail, the rotating assembly 400 includes a rotating drive member 410, a first rotating shaft 420 and a second rotating shaft 430. The first rotating shaft 420 and the second rotating shaft 430 are respectively arranged on both sides of the clamping structure 200. The rotating drive member 410 is arranged on the bracket 100 and is connected to the first rotating shaft 420. The second rotating shaft 430 is rotatably connected to the bracket 100. The first rotating shaft 420 and the second rotating shaft 430 are driven to rotate by the rotating drive member 410 to drive the clamping structure 200 and the limit reference member 300 to rotate. The first rotating shaft 420 and the second rotating shaft 430 on both sides of the clamping structure 200 are split, which better ensures the concentricity of the rotation of both sides of the clamping structure 200 and improves the rotation accuracy.

[0060] Specifically, a centering structure 440 is installed on the side of the second rotating shaft 430 away from the clamping structure 200. The centering structure 440 is installed on the bracket 100 to ensure the concentricity of the first rotating shaft 420 and the second rotating shaft 430 when the rotating driving member 410 drives the first rotating shaft 420 to rotate and drives the second rotating shaft 430 to rotate through the clamping structure 200, and automatically adjust the angle generated by the radial force of the second rotating shaft 430, so that the clamping structure 200 can be flipped stably.

[0063] Specifically, the opposite sides of the mounting frame 500 are respectively connected to the first rotating shaft 420 and the second rotating shaft 430, and the mounting frame 500 has a first mounting position and a second mounting position. The connecting line of the first mounting position and the second mounting position is perpendicular to the first rotating shaft 420, and a clamping structure 200 is respectively arranged at the first mounting position and the second mounting position.

The clamping structures 200 of the first mounting position and the second mounting position alternately clamp the top cover to improve the clamping efficiency.
[0064] In addition, a clamping structure 200 can be respectively provided on two opposite sides of the first installation position and two opposite sides of the second installation position, so that when any side of the mounting frame 500 is rotated to face the target product, each clamping structure 200 can clamp a top cover to improve efficiency.

The limit reference member 300 is disposed on the side of the clamping driving member 211 facing the first clamping jaw 212 and the second clamping jaw 213 and is located between the first clamping jaw 212 and the second clamping jaw 213 .
[0070] Specifically, the clamping assembly 210 includes a clamping drive 211, a first clamping jaw 212 and a second clamping jaw 213. The clamping drive 211 is fixed on the mounting frame 500, and the first clamping jaw 212 and the second clamping jaw 213 are arranged in parallel on both sides of the clamping drive 211.
