The controller 5 is installed on the outer side of the moving frame 4.

[0042] Specifically, trapezoidal block 16 is an isosceles trapezoid and is used to interact with connecting block 26 to realize the rotation of scraper 25. Connecting block 26 is slidably connected to the inside of connecting block 17 on the outside to transmit motion. Spring 24 is used to provide reset force, spring 19 is used to provide reset force, and controller 5 is used to control the operation of the entire device.

[0043] Working principle: When in use, place the product to be glued on the base 1, and then the controller 5 can be used to activate the drive moving component one and moving component two, so that the glue dispensing cylinder 14 and glue dispensing head move above the product. Then, the cylinder 9 pushes the dust removal component, glue dispensing cylinder 14 and connecting block 17 and other components to descend, so that the glue dispensing head of the glue dispensing cylinder 14 can be used to apply glue to the product. Before the glue dispensing process, the controller 5 can be used to activate the air pump 11, so that the product can be dusted through the air nozzle 13.

[0044] As the glue-applying cylinder 14 moves downward, it drives components such as the connecting block 17, rack 21, connecting block 26, and gear 22 to move downward until connecting block 26 slides from the upper inclined side of trapezoidal block 16 to its highest point. This causes connecting block 26 and rack 21 to move, and rack 21 is compressed. Simultaneously, rack 21 rotates gear 22, thick rod 23, spring 24, square rod 28, and scraper 25 by 180 degrees. As connecting block 26 slowly moves away from trapezoidal block 16, spring 19 resets rack 21 and connecting block 26. The rotation of rack 21 rotates gear 22, thick rod 23, spring 24, square rod 28, and scraper 25 by 180 degrees. The rotation of scraper 25 wipes the nozzle of glue-applying cylinder 14. After spraying, connecting block 10 moves fixing cylinder 102 upward until fixing block 18 connects with fixing frame 110. Upon contact, cylinder 9 pushes the dust removal assembly, glue applicator 14, and connecting block 17 upwards. As glue applicator 14 moves upwards, it drives connecting block 17, rack 21, connecting block 26, and gear 22 upwards until connecting block 26 slides from the lower inclined side of trapezoidal block 16 to the highest point, causing connecting block 26 and rack 21 to move. The movement of rack 21 puts it in a compressed state. At the same time, the movement of rack 21 drives gear 22, thick rod 23, spring 24, square rod 28, and scraper 25 to rotate 180 degrees. When connecting block 26 slowly moves away from trapezoidal block 16, spring 19 drives rack 21 and connecting block 26 to reset. The movement of rack 21 drives gear 22, thick rod 23, spring 24, square rod 28, and scraper 25 to rotate 180 degrees, thus achieving timely cleaning of the nozzle after glue applicator 14 has finished, preventing paint dripping from the nozzle.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
