Problems solved by technology
This method has the following disadvantages: (1) The length of the glue is not easy to control, so that the insulating tape after the glue is oversized and placed on the cover plate, which will directly lead to defects such as explosion points during welding around the cover plate; ( 2) Starting from the end of the battery cell to wrap the glue, it will cause the insulation film at the end of the battery cell to fold, which will cause bad problems such as short circuit of the battery cell

The invention discloses a square lithium battery core side tape wrapping device. The square lithium battery core side tape wrapping device includes a base plate, left and right supports fixed on the base plate, a clamping claw cylinder which is fixed on the base plate and is arranged between the left and right supports, a driving motor fixed on the left support, a first transmission shaft, a second transmission shaft, an active gear sleeved and fixed on the first transmission shaft, a passive gear sleeved and fixed on the second transmission shaft, two left swing rods, two right swing rods, two support shafts, two driven shafts, two tape wrapping rollers respectively sleeved and fixed on the corresponding support shafts, and left and right clamping boards in connection with the clamping claw cylinder. The square lithium battery core side tape wrapping device is advantaged in that the transmission shafts are driven by the driving motor to rotate, the support shafts are driven by the transmission shafts through the swing rods to move along guide holes on a clamping plate, so the insulation tape is driven by the tape wrapping roller to achieve tape wrapping no a side surface of a core, the structure is simple, tape wrapping is fast, and produced defective tape wrapping products are effectively reduced.
Description
technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a side surface rubber wrapping device of a square lithium battery cell. Background technique [0002] At present, before the square lithium battery cell is put into the shell, the surface of the cell is covered with insulating tape to reduce the short circuit rate of the shell, which is called "wrapping large glue" process. [0003] The current wrapping method is as follows: After the tape is pulled out for a certain distance, place the tail of the battery cell in the middle of the entire length of the tape, and then wrap it from the tail of the battery cell to the cover. This method has the following disadvantages: (1) The length of the glue is not easy to control, so that the insulating tape after the glue is oversized and placed on the cover plate, which will directly lead to defects such as explosion points during welding around the cover plate; ( 2) Start...
