[0023] A separation method of a battery film separating device comprises the battery film separating device, and the specific steps are as follows:

[0024] Step 1: separation of glue

[0025] Step 1.1: initial state, the gripper in the glue separating servo gripper mechanism and the lifting tooth in the glue separating variable-distance mechanism are in a parallel state;

[0026] The release paper on both sides of the film is torn off and placed on the conveying belt, the running driving assembly drives the conveying belt to convey the film to the conveying end of the conveying support, at this time, the rightmost strip of glue in the film is located above the lifting tooth;

[0027] Step 1.2: the gripper lowering assembly drives the gripper to descend, the gripper is inserted into the pin shaft on the corresponding lifting tooth respectively, so as to complete the clamping of the strip of glue, at this time, the film is separated into a to-be-separated glue film and a to-be-variable-distance glue film;

[0028] Step 1.3: The pressure cylinder is activated, which drives the fixed dispensing plate to press down, and the fixed dispensing plate presses the dispensing sheet tightly;

[0029] Step 1.4: The lifting mechanism moves upward, causing the clamped film to be adjusted to move upward, so that the clamped film to be adjusted is separated from the film to be separated.

[0030] Step 1.5: The servo motor works, driving the forward and reverse lead screws to rotate. The connecting seats installed on the forward and reverse lead screws move in opposite directions, completing the first pitch change and obtaining two sets of first pitch change gripper groups on the left and right.

[0031] Step 1.6: The left-side pitch-changing drive unit actuates, pulling the left-side glue-separating gripper mounting plate of the left-side first pitch-changing gripper assembly to the left;

[0032] The right-side pitch-changing drive unit moves, pulling the right-side glue-separating gripper mounting plate of the right-side first pitch-changing gripper group to the right to change pitch, completing the second pitch change, thereby completing the pitch-changing separation of all the films to be pitched.

[0033] During the pitch change process, since the follower lower pitch change seat is installed on the guide rail, when the glue dispensing servo gripper mechanism performs the first pitch change and the second pitch change, each lifting tooth in the follower lower pitch change seat also moves simultaneously.

[0034] Step 1.7: The lifting mechanism descends and returns to the initial position. Each strip of adhesive in the variable pitch film is attracted by the corresponding gripper. At the same time, the pushing cylinder is activated to push the variable pitch lifting teeth together, completing the reset of the lifting teeth.

[0035] Step 1.8: The robotic arm drives the glue-dispensing servo gripper mechanism to move to the station of the single battery. The corresponding gripper lifting component moves, causing the strip glue on the corresponding gripper to be pasted on both sides of the single battery to be glued in one go, completing the gluing of 2 single batteries. This process is repeated.

[0036] Step 2: Remove adhesive.

[0037] Furthermore, the specific steps for removing the adhesive in step 2 are as follows:

[0038] Step 2.1: The unwound adhesive cleaning device has unused adhesive cleaning rolls on it, and the rewind adhesive cleaning device rewinds the used adhesive cleaning rolls. The automatic adhesive cleaning mechanism is started periodically according to the production cycle and the adhesiveness of the film.

At this time, the drive component drives the conveyor belt to rotate, and the adhesive removal motor starts, driving the adhesive removal winding device to take in the material, thereby driving the adhesive removal unwinding device to release the material at the same time, and finally completing the cleaning of residual adhesive on the conveyor belt.

[0040] Step 2.2: After the glue cleaning is completed, the glue cleaning mode switching device is lowered, the glue cleaning motor is stopped, and the next glue cleaning is waited.
