Problems solved by technology
The advantage of the double cylinder is that the final force is uniform, which can avoid the force deflection caused by the change of the length of the module. The disadvantage is that the synchronization of the double cylinder is poor, and the lifting limit is adjusted at the bottom of the frame, which makes debugging difficult.
The advantage of the electric cylinder drive is that there is no need for a limit position, and it can be easily compatible with products of different heights. The disadvantage is that due to the large change in the length of the module, the force deflection of the busbar sheet will be uneven when the load is eccentric, and the cost of the electric cylinder is high.

The invention relates to a lithium battery laser welding clamp jacking mechanism which comprises a first substrate, a second substrate, a cylinder, profiling inclined blocks, rollers, a guide rail, aguiding column, a linear bearing and a movable support. The second substrate is installed above the first substrate through the guiding column and the linear bearing and can ascend and descend along the guiding column, the guide rail is installed on the first substrate, the movable support is slidably installed on the guide rail and can be driven by the cylinder to slide, the profiling inclined blocks are installed at the two sides of the movable support, the bottom of the second substrate is provided with the rollers which are in corresponding abutting fit with the profiling inclined blocks,and the tops of the profiling inclined blocks are horizontal. Synchronous jacking of a laser welding clamp can be achieved, deflection is effectively avoided, self-locking limiting of the jacking height can be achieved, the jacking positioning accuracy is ensured, and the effect of stable positioning is achieved.
Description
technical field [0001] The invention belongs to the technical field of lithium battery busbar laser welding, and in particular relates to a jacking mechanism for a lithium battery laser welding fixture. Background technique [0002] In the existing lithium battery busbar welding process, the jacking mechanism has two structures of double cylinder and electric cylinder drive. The advantage of the double cylinder is that the final force is uniform, which can avoid the force deflection caused by the change of the length of the module. The disadvantage is that the synchronization of the double cylinder is poor, and the jacking limit is adjusted at the bottom of the frame, which makes debugging difficult. The advantage of the electric cylinder drive is that there is no need for a limit position, and it can be easily compatible with products of different heights. The disadvantage is that due to the large change in the length of the module, the force deflection of the busbar sheet ...
