[0024] In this embodiment, the automatic adhesive tape sticking machine includes three adhesive tape sticking units 3, and the distribution of the adhesive tape sticking units 3 makes the adhesive tapes stuck evenly distributed along the circumferential direction of the annular baffle, that is, the working station angle formed between the three adhesive tape sticking units 3 is 120°, so that after a workpiece passes through the automatic adhesive tape sticking machine, three adhesive tapes are stuck to the inner wall of the reel and the outer end faces of the annular baffles at both ends.

[0026] The positioning bottom plate 221 of the workpiece positioning die 22 is connected to the crawler-type transmission belt 21 through a hollow fixing plate 223 and two connecting columns 224. A space for the lower fitting brush head 351 and the adhesive tape shearing mechanism 33 to move is formed between the positioning bottom plate 221 and the hollow fixing plate 223; the hollow part of the hollow fixing plate 223 is large enough for the material clamping gripper 325 of the adhesive tape clamping and lifting mechanism 32 and its first longitudinal slide rod 323 to pass through.

[0027] The adhesive tape feeding mechanism 31 includes an adhesive tape unwinding roller 311, an unwinding roller bracket 312, and a guide roller 313.

The lower laminating mechanism 35 is fixedly installed on the frame 1; the upper laminating mechanism 34 and the lower laminating mechanism 35 respectively include a laterally arranged laminating driving cylinder 344 (352) and a laminating brush head (341, 351), and the rotating shaft of the laminating brush head (341, 351) is connected to the output end of the laminating driving cylinder 344 through an L-shaped connecting block 345, and a U-shaped space 346 for the adhesive tape to pass through is formed between the L-shaped connecting block 345 and the rotating shaft of the laminating brush head (341, 351); the lifting and lowering adjustment drive of the adhesive tape clamping and lifting mechanism 32 and the upper laminating mechanism 34 can also be realized by an electric push rod. The distance between the upper and lower laminating mechanisms is adjustable, so that workpieces of different heights can be suitable for gluing operations; the gluing brush head adopts a brush roller method, so that the brush head and the adhesive paper fully contact and thus the adhesive paper and the end surface of the baffle are fully fitted.

[0029] In this embodiment, according to actual installation conditions, from the perspective of saving space and improving bracket utilization, the upper and lower laminating mechanisms can also be installed on the first vertical bracket of the adhesive tape clamping and lifting mechanism.

[0030] The automatic glue laminating machine also includes a material unloading unit 4, which has an expandable support claw 41 extending from the top into the interior of the workpiece A reel, and a material unloading drive component 42 that drives the expandable support claw 41 to rise and fall as a whole and move laterally. After the expandable support claw 41 avoids the positioning column 222 and contacts the inner wall of the workpiece reel, the workpiece is taken out of the workpiece positioning mold 22 upward, and then transferred to the conveyor belt 43 and sent to other workstations without manual unloading. In this embodiment, the expandable support claw 41 is driven by a three-claw cylinder.

[0031] Of course, the device of the present invention also includes electronic components such as an electric control box and an in-position sensor, which are installed according to the parameter settings such as the stroke position and execution time of each action mechanism in the present invention to achieve automatic control. This is a conventional technology in the field and will not be described in detail.

[0032] The working process of the present invention is as follows: First, the upper bonding brush head 341 and the lower bonding brush head 351 respectively move radially under the drive of their drive components to positions near the center above and below the inner hole of the end face of the annular baffle, so that there is enough space, namely the U-shaped space 346, between the brush head and the inner edge of the annular baffle for the material clamping gripper 325 of the adhesive tape clamping and lifting mechanism 32 and the first longitudinal slide rod 323 to pass through; then the adhesive tape clamping and lifting mechanism 32 clamps the end of the adhesive tape, and under the drive of its first drive component 324 of the drive component, the adhesive tape is tractioned vertically upward, so that the adhesive tape sequentially passes through the gap between the lower bonding brush head 351 and the inner edge of the lower annular baffle, penetrates through the inside of the winding head, and passes out through the gap between the upper bonding brush head 341 and the inner edge of the upper annular baffle, so that the upper end of the adhesive tape reaches the set height. Then the adhesive tape cutting mechanism 33 extends from the direction parallel to the adhesive tape and cuts the adhesive tape. Then the upper bonding brush head 341 and the lower bonding brush head 351 respectively move radially towards the outer edge of the baffle at the same time, so that the upper and lower ends of the adhesive tape are respectively attached to the upper and lower baffle end faces. And when the upper end of the adhesive tape is in contact with the inner edge of the upper baffle, the material clamping gripper 325 of the upper adhesive tape clamping and lifting mechanism 32 releases the adhesive tape, so that the upper end of the adhesive tape is fully attached to the upper baffle end face; thus, the adhesive tape pasting operation at this station is completed; according to needs, a number of adhesive tapes can be pasted at different circumferential angles; for example, the present invention is provided with three pasting units, so that three adhesive tapes can be pasted at intervals along a 120-degree circumference on the upper and lower end faces of the baffle.

[0033] The automatic adhesive tape pasting machine of the present invention can realize automatic loading and unloading through a manipulator, and the intermediate pasting process is automatically completed by multiple pasting units. Therefore, the production efficiency is high, the manual operation is less, and the processing cost can be greatly reduced and the product quality can be improved.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
