Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a battery module shaping device. Background Art

[0002] After the battery cells are stacked, the battery pack needs to be pressurized and shaped to ensure the size of the module and the flatness of the cell pack. In particular, if the height difference of the pole surface is too large, it will affect the subsequent busbar welding quality and cause cold soldering in the module busbar welding.

[0003] The current module shaping devices basically perform full-surface extrusion and shaping on all surfaces of the battery cell group. The size of a single battery cell in the battery cell group cannot be adjusted individually, and the battery cells are bonded together with adhesive spacers, making it difficult to move the battery cells by shaping. Due to processing errors in the size of a single battery cell, the pole surface sizes of individual batteries are still inconsistent after shaping the entire surface. If the pressure or size does not meet the standard after full-surface extrusion and shaping, the entire battery cell group will be defective and the entire battery cell group needs to be scrapped, resulting in serious waste of materials.

If it is detected that the pole of a certain battery cell is not aligned with the other poles 4-3, the background controller detects whether the poles 4-3 of each battery cell are in a straight line. On a straight line, the background controller controls the two driving members 2 34 located on both sides of the battery cell to extend or retract, and by squeezing and adjusting the battery, all the battery cell poles 4-3 of the battery module 4 to be shaped are on a straight line and do not exceed the predetermined offset threshold. After the adjustment, the driving member 2 34 is reset; then, the driving member 4 10 extends to drive the movable plate to move downward, thereby driving the top shaping plate 9 to move downward, so that the multiple top shaping blocks 6 are respectively in contact with the tops of the multiple batteries of the battery module 4, and then, the multiple driving members 15 extend to push the multiple bottom shaping blocks 14 upward respectively, ensuring that the top of each battery cell is in contact with the corresponding top shaping block 6, and the module pre-shaping is completed at this time;

[0050] Afterwards, the driving member 4 10 contracts to drive the top shaping plate 9 to lift upward, and the driving member 8 26 extends out. Under the action of the driving member 10 30, the two film-tearing jaws 29 clamp the partitions between the battery cells, and then the driving member 6 20 drives the supporting plate 3 21 upward to pull out the partitions; driven by the moving module 2 12, the partitions between the battery cells are pulled out in turn; afterward, the film-tearing jaws 29 are aligned with the release paper on the spacer 4-2 and the film-tearing jaws 29 clamp the release paper, and the driving member 6 20 drives the supporting plate 3 21 upward to tear off the release paper; after all the partitions 4-1 are pulled out and the release papers on all the spacers 4-2 are torn off, the driving member 4 10, multiple driving members 2 34, and the driving member 3 40 extend out at the same time to press the battery module 4 up and down and left and right. At this time, the shaping of the battery module 4 is completed;

[0051] After the shaping is completed, the driving member 4 10, the driving member 2 34, the driving member 3 40, and the driving member 13 35 are reset, and the driving member 6 20 pushes the supporting plate 3 21 downward, and at the same time, multiple clamping blocks 25 are moved downward to both sides of the battery module 4 that has completed shaping, and multiple driving members 7 24 on both sides respectively push multiple clamping blocks 25 to clamp the battery module 4 that has completed shaping, and then the driving member 6 20 drives the supporting plate 3 21 upward to lift the battery module 4 that has completed shaping to a certain height, and then the driving member 11 17 drives the lifting plate 18 to descend and reset, and the two driving members 5 45 The two support rods 44 are driven to move respectively so that the two support rods 44 are close to each other; then the driving member six 20 pushes the support plate three 21 downward, and the multiple driving members seven 24 contract to drive the clamping block 25 to reset and release the battery module 4 that has completed the shaping. At this time, the battery module 4 that has completed the shaping is supported by the two support rods 44; the pneumatic positioning pin 48 descends and resets to disengage from the positioning hole of the tray, and then the lifting cylinder 49 contracts to put the tray back on the logistics line 2, and then the lifting stop member 46 descends and resets, and the logistics line 2 transports the battery module 4 that has completed the shaping to move to the next process.
