Description

Technical Field

[0001] The present application belongs to the technical field of battery cell module production equipment, and in particular, relates to a battery cell module processing device. Background Art

[0002] During the processing of the battery cell module, the poles and busbars of the battery cell module need to be welded together. The welding process of the poles and busbars of the battery cell module currently includes two process steps: pole cleaning and busbar welding. In both process steps, the poles of the battery cell module need to be positioned.

[0003] The existing positioning method is to position the pole before cleaning the pole, and to position the position to be welded before welding the busbar. Because the busbar needs to be installed on the pole after cleaning the pole and before welding, the busbar welding station cannot position the pole, so the busbar welding station needs to manually calibrate the position to be welded one by one. Obviously, this calibration method is inefficient and has large errors. Utility Model Content

[0009] After the conveying device conveys the battery cell module cleaned by the pole cleaning device to the busbar loading station, the busbar is placed on the pole corresponding to the upper surface of the battery cell module by a manual or automatic loading device;

[0010] The welding device is arranged at the welding station, and the welding device includes a second positioning component and a welding mechanism.

[0060] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0061] During the processing of the battery cell module, the poles and busbars of the battery cell module need to be welded together. The welding process of the poles and busbars of the battery cell module currently includes two process steps: pole cleaning and busbar welding. In both process steps, the poles of the battery cell module need to be positioned.

[0062] The existing positioning method is to position the pole before cleaning the pole, and to position the position to be welded before welding the busbar. Because the busbar needs to be installed on the pole after cleaning the pole and before welding, the busbar welding station cannot position the pole, so the busbar welding station needs to manually calibrate the position to be welded one by one. Obviously, this calibration method is inefficient and has large errors.

[0064] Specifically, the characteristic point is a through hole on the end plate of the battery cell module or a top corner of a battery cell in the battery cell module.

[0065] It can be seen that the cell module processing device proposed in the present application realizes automatic cleaning and welding of the cell module poles through the cooperation of the conveying device 10, the pole cleaning device 20 and the welding device 30; at the same time, by determining the position of each pole and the position offset parameter between the pole and the characteristic point at the pole cleaning station 11, only the position information of the characteristic point needs to be determined at the welding station 13, and the position coordinates of each pole of the cell module 40 at the welding station are automatically calculated in combination with the position offset parameter between the pole and the characteristic point, thereby determining the position to be welded of the cell module 40.

[0071] Specifically, the second driving member 340 adopts a double-axis transfer module composed of a transverse movement module and a lifting module.

[0072] Specifically, a first dust removal component 50 is provided on the first clamping block 342, and the first dust removal component 50 is configured to remove impurities and smoke generated during welding by the laser welder; the first dust removal component 50 includes a first dust suction end 500, a first dust suction pipeline 501 and a first dust suction device (not shown in the figure), the first dust suction end 500 is provided on each first clamping block 342 and is connected to the cavity 3420, the first end of the first dust suction pipeline 501 is connected to the first dust suction end 500, and the second end of the first dust suction pipeline 501 is connected to the first dust suction device, and the first dust suction device is configured to extract air from the first dust suction pipeline 501 so that a negative pressure is formed in the first dust suction pipeline 501 to suck away impurities and smoke.

[0073] It can be seen that by setting m*n first clamping blocks 342, each first clamping block 342 corresponds to a welding position.

[0125] Adjust the laser output position to the most suitable working position according to the process requirements.

[0126] Specifically, the most suitable working position refers to a position where the laser hitting the pole is circular and concentric with the pole.

[0127] It can be seen that before controlling the laser component 22 for trial operation, by pasting the positioning tool on the pole, the laser component 22 is controlled to hit the laser on the positioning tool, and the positioning camera of the first positioning component 21 is used to observe the position information left by the laser on the positioning tool of each pole, thereby realizing the calibration of the laser output position.
