[0003] The existing incoming film is mostly in roll form, and the current automated gluing equipment is designed based on roll film. The sheet-like adhesive tape is pasted manually, which causes serious waste of manpower. In addition, manual adhesion has a series of quality risks such as large wrinkles, misalignment, bubbles, etc., and production efficiency cannot be guaranteed. Utility Model Content

[0026] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0027] like Figure 1 Figure 3 As shown, a new energy battery cell side glue sticking and peeling device is disclosed, comprising:

[0028] The fuselage stand 19 is provided with a first-direction glue taking drive unit 3, the first-direction glue taking drive unit is connected to the second-direction glue taking drive unit 2, and the fuselage stand is provided with a to-be-peeled glue paper bin 4, a waste material recovery slot 6 and a glue paper secondary positioning mechanism 18 in sequence along the movement direction of the first-direction glue taking drive unit 3, and the bottom of the second-direction glue taking drive unit is connected to a glue peeling actuator;

[0029] The gluing mechanism is used to stick the torn adhesive tape 8 on the adhesive tape secondary positioning mechanism 18 to the side surface of the battery cell in the wire carrier tray.

[0030] In this embodiment, the waste recycling tank 6 includes a release paper gripper 7 that cooperates with the adhesive peeling actuator. The release paper gripper 7 is a clamping cylinder that is used to clamp the release paper extending from one side of the adhesive paper to be peeled off, thereby peeling off the release paper.

[0031] In this embodiment, a tape bin slide 16 is provided at the bottom of the tape bin 4 to be torn, and the tape bin slide is slidably connected to the fuselage stand 19 through a rodless cylinder. The tape bin slide 16 can reciprocate in the X-axis direction through the rodless cylinder. After the tape bin slide 16 moves to the target position along the negative direction of the X-axis, it is convenient to manually place the tape to be torn into the 8 tape bins 4.

[0032] like Figure 2As shown, a positioning cylinder 20 is provided on the side of the adhesive tape secondary positioning mechanism 18, and the positioning cylinder 20 is used to center the adhesive tape to ensure the positioning accuracy of the adhesive tape.

[0033] like Figure 1 and 2 As shown, the glue peeling actuator is a vacuum suction cup Ⅰ14, and the vacuum suction cup Ⅰ14 is equipped with a vacuum detection device Ⅰ1. The glue sticking actuator is a vacuum suction cup Ⅱ15, and the vacuum suction cup Ⅱ15 is equipped with a vacuum detection device Ⅱ11. The vacuum detection device is used to detect the adhesive tape material sucked by the vacuum suction cup to effectively prevent abnormalities such as empty grabbing and falling.

[0034] like Figure 3 As shown, the gluing mechanism includes a robot 9 and a robot fixture 10. The robot fixture 10 is installed at the end of the robot 9. The robot fixture 10 is provided with a gluing actuator and a clamping mechanism. The robot in this embodiment is a four-axis robot.

[0035] like Figure 2 As shown, the pressing mechanism includes a roller pressing cylinder 12 and a roller 13. The roller 13 is provided at the power output end of the roller pressing cylinder. The robot drives the robot clamp to grab the torn adhesive tape and paste it on the large surface of the battery cell in the line tray, and makes reciprocating motion in the Y direction. By driving the roller to repeatedly press the upper surface of the initially pasted film, it is ensured that the film is firmly and reliably pasted and completely fits the large surface of the battery cell without bubbles.

[0036] like Figure 1 As shown, a brush 17 is provided on the side of the to-be-torn adhesive paper bin. The arrangement of the brush 17 prevents the vacuum suction cup Ⅰ14 from effectively pulling the next adhesive paper 5 to be torn when sucking the to-be-torn adhesive paper 5.

[0037] like Figure 2-Figure 3 As shown, the first direction glue taking driving unit 3 includes a slide rail 21 relatively arranged on both sides of the fuselage stand 19, and a slider 22 is respectively arranged on the slide rail 21, and a crossbeam 23 is arranged on the two sliders 22, and the crossbeam 23 is used to install the second direction glue taking driving unit 2;

[0038] The second direction glue taking drive unit 2 includes a vertical plate 24 arranged on the cross beam 23, a vertical slide rail 25 is arranged on the vertical plate 24, the slide rail 25 is equipped with a slider 26, a fixed plate 27 is arranged on the outer side of the slider 26, and the bottom of the fixed plate 27 is connected to an actuator horizontal plate 28 for installing an actuator 2; the first direction glue taking drive unit 3 moves along the X-axis direction, and the second direction glue taking drive unit 2 moves along the Z-axis direction.

[0039] The specific working process of the utility model is as follows:

[0040] The adhesive paper bin slide 16 can make reciprocating motion in the X-axis direction through the rodless cylinder. After the adhesive paper bin slide moves to the target position along the negative direction of the X-axis, the adhesive paper to be torn is placed manually in the 8 adhesive paper bins 4. After the adhesive paper bin slide 16 moves to the target position along the positive direction of the X-axis, the first direction adhesive driving unit 3 and the second direction adhesive driving unit 2 simultaneously suck 4 pieces of adhesive paper 5 to be torn to the release paper gripper 7, and the release paper extending from one side is clamped by the clamping claw cylinder. The second direction adhesive driving unit 2 moves downward to peel off the release paper, and the clamping claw cylinder is reset. The peeled release paper naturally falls into the waste recovery slot 6, and then the torn film 8 is placed on the adhesive paper secondary positioning mechanism 18, and the film is centered by the positioning cylinder 20 to ensure the positioning accuracy of the film;

[0041] The robot 9 drives the robot clamp 10 to grab the torn adhesive tape 8 and stick it to the large surface of the battery cell in the line carrier tray. The cylinder 12 with roller is extended downward to place the roller 13 against the upper surface of the initially pasted film. The robot 9 makes reciprocating motion in the Y direction and repeatedly presses the upper surface of the initially pasted film to ensure that the film is firmly and reliably pasted and completely fits the large surface of the battery cell without bubbles.
