Description

Technical Field

[0002] With the rapid development of the new energy vehicle industry, the categories, models, and specifications of battery modules are increasing. When performing side seam welding on new energy battery modules, it is necessary to shape the battery cell module and the side plate in advance, and adjust and stabilize the side plate and the end plate to ensure that the side plate and the end plate can fit on the battery cell module during the welding of the battery cell module, so as to ensure the quality of the processed new energy battery. Currently, most of the welding of the end plate and the side plate of the battery module uses laser welding with a high degree of automation. However, in the prior art, most of the welding platforms for the end side plates of modules with a high degree of automation can only adapt to the welding of end side plates of a single size. The reason is that the platform cannot complete the automatic adjustment in the length and width directions of different modules during welding, and the welding assembly positioning jig can only achieve the assembly and positioning of a single specification of battery module, and cannot be compatible with different specifications of battery modules. This makes it necessary to replace different positioning jigs when producing different specifications of battery modules, which is inconvenient to operate and has low efficiency.

[0030] The side seam welding and shaping jig or the module shaping assembly provided by the above embodiments has the following beneficial effects:

[0031] 1. Through the movable connection between the first movable plate and the frame assembly, the positions of the material placing platform and the side plate clamping assembly can be adjusted. Through the movable connection between the second movable plate and the frame assembly, the positions of the first side plate shaping assembly and the positioning mechanism can be adjusted. By changing the distances between the first movable plate and the second movable plate and the fixed plate, it is convenient to weld side plates and battery cell modules of different sizes. The material placing platform, the end plate clamping assembly, and the side plate clamping assembly are arranged in a "cross" shape. The workpiece is placed on the material placing platform, the end plate is pressed by the end plate clamping assembly, the side plate is shaped by the side plate shaping assembly, the side plate is clamped by the side plate clamping assembly, and the positioning mechanism positions the side plate, which is convenient for welding the side plate and the battery cell module, ensuring the accuracy of the corresponding positions when the end plate and the side plate are welded to the battery cell module, and avoiding deviations during welding and affecting the processing quality of the battery cell module.

[0032] 2. The third movable plate is movably connected to the first movable plate through a slide rail. The distance between the third movable plate and the material placing platform is changed by the second electric cylinder to make the side plate shaping substrate fit the side plate, which is convenient for adjustment according to battery cell modules of different sizes. A side plate shaping positioning block is mounted on the third movable plate, and a side plate shaping hook and a side plate upper pressing block are mounted on the side plate shaping positioning block to shape and fix the side plate. The position of the side plate shaping positioning block on the third movable plate is changed by the pushing electric cylinder, and the distances between the side plate shaping hook and the side plate upper pressing block and the side plate shaping substrate are changed, which is convenient for using side plates of different thicknesses. The side plate shaping hook ensures the position fit between the side plate and the side plate shaping substrate, and the side plate upper pressing block fixes and clamps the side plate. After shaping, the side plate is adsorbed and fixed by a vacuum chuck.

[0033] 3. The movement of the shaping end plate is controlled by the shaping cylinder installed on the shaping bracket to adjust the position of the side plate, ensuring the stability when the side plate is connected to the battery cell module. The shaping cylinder pushes the shaping end plate to slide along the shaping bracket to shape the side plate, and one end of the side plate is extended into the welding baffle, facilitating the welding of the side plate to the battery cell module. The welding baffle is adjusted by the copper nozzle pressing cylinder, which is convenient for adjusting the welding baffle according to the size of different side plates. A through hole for the movement of the welding baffle is provided on the copper nozzle support frame, facilitating the adjustment of the welding baffle according to the size of the side plate under the control of the copper nozzle pressing cylinder.

[0034] 4. After the battery cell module is placed on the feeding platform, it is rectified by the module side shaping mechanism. After rectification, the battery cell module is pressed by the pole pressing and limiting mechanism, and then the side plate is installed by the side plate clamping assembly. When the battery cell module is placed on the feeding platform, the bracket pushing cylinder pushes the side shaping bracket to move up and down along the slide rail, driving the side pressing module to move up and down. The side shaping cylinder on the cylinder mounting plate pushes the side pressing module to move along the slide rail to shape the battery cell module, and the side pressing module is locked by the pin cylinder, facilitating the side pressing module to shape the battery cell.

[0035] 5. The pole pressing cylinder pushes the pole roller assembly mounting plate to move up and down, so that the pole pressing and limiting mechanism presses the top of the battery cell module, facilitating the fixation of the battery cell module. When the pole roller assembly contacts the battery cell module, the roller contracts, and the pole pressing spring tops the roller and gives a repulsive force to the pole roller assembly mounting plate and the battery cell module, facilitating the fixation of the battery cell module and protecting the battery cell module at the same time.
