[0033] In the embodiment of the present invention, the driving mechanism includes a rodless cylinder connected between the movable base and the working platform, and a slider and rail moving pair 7 is connected between the front part of the movable base and the working platform.

[0034] The rodless cylinder provides power for the movement of the glue preparation mechanism, and the slider and rail moving pair is used for guiding the translation.

[0035] In the embodiment of the present invention, the front end of the movable base is provided with a positioning pin 9 which is driven to rise and fall by the first lifting cylinder 8, the top table of the working platform is provided with a limiting mechanism at the pushing end point of the movable base, and is provided with a positioning pin hole 10 for inserting the positioning pin into place.

Then, the positioning pin at the end point of pushing is lowered and inserted into the positioning pin hole to ensure the stable positioning of the glue preparation mechanism after it is pushed into place.

[0038] The positioning pin will be disengaged from the positioning pin hole first when the glue preparation mechanism is pushed out next time.

[0045] Specifically, the left width limiting baffle is locked on the left and right extending grooves 30 of the stripping plate by bolts and nuts, and the right width limiting baffle is locked on the mounting internal threaded hole of the stripping plate by bolts. By loosening and tightening the bolts and nuts of the left width limiting baffle, the distance between the left and right width limiting baffles can be changed to adapt to the width of the adhesive tape.

[0046] In the embodiment of the present invention, the upper surface of the peeling plate is fixedly connected with a telescopic cylinder 31 on the side of the adhesive tape travel channel, the piston rod of the telescopic cylinder is axially oriented to the left and right and is fixedly connected with a fiber optic sensor 32 with a detection head facing downward toward the top surface of the wedge-shaped guide plate.

[0047] The telescopic cylinder is used to extend and retract and drive the optical fiber sensor to reciprocate and translate for detection, and is used to detect whether the adhesive strip on the upper surface of the lower release paper reaches the predetermined position of the wedge-shaped guide plate.

[0048] In the embodiment of the present invention, the upper release paper winding assembly includes an upper winding roller 33 installed on a movable base, and the lower release paper winding assembly includes a second reversing roller 34, an active flower roller 35 is arranged behind the second reversing roller, a driven rubber roller 36 is arranged below the active flower roller, and a lower winding roller 37 is arranged behind the driven rubber roller.

[0049] In an embodiment of the present invention, the glue preparation method of the glue preparation device of the battery cell glue sticking machine is: 1. When the glue preparation mechanism on one glue preparation station is in the state of putting film, the glue preparation mechanism on the other glue preparation station is pushed out to change the film. When the new film is replaced, the glue preparation mechanism is pushed back in. One in use and one in reserve can be achieved, so that glue can be changed without stopping the machine, and the work efficiency of the production line is improved.

[0050] When the glue preparation mechanism is pushed in or out on the glue preparation station, the support legs are used to support the rear of the glue preparation mechanism, and the rollers roll on the ground.

[0051] 2. When the above-mentioned glue preparation mechanism is pushed into place, the front end of the movable base first contacts the buffer head of the oil pressure buffer for buffering, and finally stops moving forward after contacting the limit screw. Then, the positioning pin at the end point of pushing is lowered and inserted into the positioning pin hole to ensure the stable positioning of the glue preparation mechanism after it is pushed into place.

[0052] The positioning pin will be separated from the positioning pin hole first when the glue preparation mechanism is pushed out next time.

[0053] 3. The glue preparation mechanisms on the two glue preparation stations perform roll changing operations in turn according to the above steps.

[0054] In an embodiment of the present invention, the glue stripping method of the glue preparation mechanism of the glue preparation device of the battery cell glue sticking machine is: The film has a three-layer structure, with a cut adhesive strip sandwiched between two layers of release paper.

[0055] 1. The film roll is installed on the material roll roller, and the adhesive paper is first wound downward on the tensioning roller, wherein the upper release paper 38 is torn and wound upward on the upper winding roller, and the lower release paper 39 extends forward with the adhesive strip through the transition roller, and passes through the upper surface of the supporting plate, the peeling plate, and the wedge-shaped guide plate in sequence, wherein the lower release paper is wound downward from the front edge of the wedge-shaped guide plate in sequence through the first reversing roller, the second reversing roller, the active flower roller and the driven rubber roller, and finally wound on the lower winding roller.

[0056] 2. When stripping glue, when the frontmost glue strip reaches the predetermined position of the wedge-shaped guide plate through the optical fiber sensor, the pressure block presses down the glue paper supporting the flat plate, and the material roll roller stops unwinding. The glue suction cup 40 of the next station of the battery cell glue machine moves to the top of the peeling flat plate and the wedge-shaped guide plate and adsorbs downward on the corresponding glue strip. Among them, the glue suction cup is foamed silicone, which is also treated with non-stick, and uses vacuum to adsorb the glue strip.

[0057] 3. Then, the movable frame moves backward, carrying the peeling plate, wedge-shaped guide plate and the first reversing roller. At the same time, the lower release paper winding assembly works, and the active flower roller provides the winding power, so that the lower release paper is kept synchronously recovered and the paper mold is tight without loosening. The rubber strip and the lower release paper produce relative displacement, so that the rubber strip is separated from the lower release paper, and the subsequent rubber strip is transported to the next station by the glue suction cup.

[0058] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
