Description

Technical Field

[0001] The utility model relates to the field of lithium batteries, in particular to a glue-tearing mechanism with multiple cylinders connected in series. Background Art

[0002] With the continuous development of the new energy vehicle field, the market demand for power batteries has also expanded. At the same time, the requirements for power battery packs are also constantly increasing, and higher standards and requirements are also put forward for the production process and efficiency of lithium battery module PACK. Before the single battery cells are stacked into modules, spacers must be attached to the surface of the battery cells. The spacers are affixed with battery cell release paper, which needs to be torn off after use. At the beginning, manual glue tearing was used. After the development of technology, the existing glue tearing mechanisms in the lithium battery industry are generally three-axis trusses or four-axis robots. However, these two forms are servo-driven, occupy a large space, are costly, and are more complicated to debug. These structures are also not suitable for environments with limited space and projects with cost control. Utility Model Content

[0024] The second translation cylinder 3 is installed on the first rotation cylinder 2. When the peeling mechanism claws reach the battery cell release paper 9, the claw cylinder 8 moves horizontally to allow the battery cell release paper 9 to enter the inside of the claw cylinder 8, making it easier for the claw cylinder 8 to clamp the battery cell release paper 9.

[0025] The switching mechanism 4 switches the upper connected mechanism by 90 degrees, and fixes the action planes of the third translation cylinder 5 and the fourth rotation cylinder 6 on the vertical plane.

[0026] The third translation cylinder 5 rises after the clamping claw cylinder 8 clamps the battery cell release paper 9, driving the release paper up a distance to avoid interference with the battery cell for the next step of rotation.

[0027] The fourth rotary cylinder 6 drives the entire clamping claw cylinder 8 to rotate perpendicular to the horizontal plane, and rotates an angle when clamping the battery core release paper 9, so as to facilitate tearing the battery core release paper 9; the clamping claw cylinder 8 is used to clamp the release paper.

The first rotary cylinder 2 and the second translation cylinder 3 and between the third translation cylinder 5 and the fourth rotary cylinder 6 are connected via the mounting plate.

[0030] The first rotary cylinder 2, the second translation cylinder 3, the third translation cylinder 5, the fourth rotary cylinder 6 and the clamping cylinder 8 are all provided with a center sealing valve.

After the workpiece is in place, the first rotary cylinder 2 rotates into place, such as Figure 1 As shown; when the clamping claw cylinder 8 is in the open state, the second translation cylinder 3 moves to make the clamping claw cylinder 8 cover the battery cell release paper 9; the clamping claw cylinder 8 clamps the release paper; the third translation cylinder 5 rises, driving the battery cell release paper 9 up a distance, so as to avoid interference from the battery cell for the next rotation; the fourth rotary cylinder 6 rotates to lift the battery cell release paper 9 to a certain angle; then the first rotary cylinder 2 rotates significantly to tear off the battery cell release paper 9, and the battery cell release paper 9 is torn off; the clamping claw cylinder 8 is released, and the battery cell release paper 9 falls into the recycling box.
