Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1 to 4, a tab welding mechanism includes a lower platen 1 driven by a lower press, a mounting block 2 mounted on an end portion of a lower surface of the lower platen 1, and a plurality of lower press assemblies 3 movably disposed on the mounting block 2 and penetrating through the lower platen 1;

the pressing assemblies 3 are uniformly arranged at the end parts of the mounting blocks 2, and the pressing assemblies 3 comprise pressing blocks 31, guide columns 32 arranged at the upper ends of the pressing blocks 31, supporting columns 33 arranged above the guide columns 32, and elastic pieces 34 sleeved outside the guide columns 32 and respectively supporting the pressing blocks 31 and the supporting columns 33 up and down;

the mounting block 2 is provided with a mounting groove 21, the mounting groove 21 is used for mounting the pressing component 3, and the pressing block 31 is provided with at least two groups of guide posts 32, a jacking post 33 and an elastic piece 34.

The pressing block 31 adopts a groove design, so that sufficient space is reserved for spot welding of products while the downward pressure is ensured, and meanwhile, the contact area with a PCB (printed circuit board) is reduced, and the phenomenon that the products are bad due to the fact that the pressing claw presses the product parts is prevented; the bump 311 at the end of the pressing block 31, the bump 311 is disposed at two sides of the end of the pressing block 31, and a space 312 is provided between the bump 311 and the bump 311, the space 312 is used for the laser beam to pass through, the bumps 311 at two sides respectively press two sides of the position where the tab needs to be welded, and the position where the tab needs to be welded is disposed at the space 312.
