A glue storage box 317 is fixed to the left side of the top surface of the bottom plate 1. The glue storage box 317 is located on the left side of the two limit plates 2. A glue inlet is provided on the top surface of the glue storage box 317. A liquid pump 318 is fixedly installed at the bottom end of the glue storage box 317. , a hose is provided on the top surface of the liquid pump 318, the hose of the liquid pump 318 penetrates and is fixed to the inner top of the glue storage box 317, one end of the hose of the liquid pump 318 is fixedly connected to the outer wall top of the electric spray head 316, the nozzle of the electric spray head 316 is located below the round tube 315, the servo motor 312 shaft drives the disc 313 to rotate, the disc 313 drives the bracket 314 to rotate, the bracket 314 drives the round tube 315 to rotate, and the round tube 315 drives the electric spray head 316 to rotate, so that the electric spray head 316 can rotate into an arc to apply glue to the windshield during the process of applying glue to the curved edge of the windshield, so as to avoid the difficulty of the automotive parts gluing device to apply glue to the curved edge of the windshield, resulting in poor gluing effect of the equipment;

[0034] A lower support module 32 is provided on the bottom surface of the bracket 314, and the lower support module 32 includes a spring rod 321, which is fixed to the bottom surface of the bracket 314, and the spring rod 321 is located in the middle below the disc 313. A ball shell 322 is fixed to the bottom surface of the spring rod 321, and a rubber ball 323 is rotatably installed on the inner wall of the ball shell 322. The windshield of the two limit plates 2 is on the movement trajectory of the rubber ball 323. When the electric spray head 316 rotates into an arc, the rubber ball 323 is against the windshield, so that the electric spray head 316 can be supported by the rubber ball 323 when rotating to apply glue, thereby reducing the amplitude of the electric spray head 316, and avoiding the electric spray head 316 from vibrating when rotating during the process of applying glue to the curved edge of the windshield by the automotive parts gluing device, causing the glue to be distorted.

[0035] When in use, the bottom plate 1 supports the limit plate 2, and the staff places the windshield on the limit plate 2. The limit column on the limit plate 2 limits the windshield. Since the edge of the car windshield is curved during the process of gluing the car windshield, it is difficult for the equipment to gluing the curved edge of the car windshield. At this time, the staff starts the electric slide rail in the bottom plate 1, and the electric slide rail drives the mechanical arm 3 to move back and forth. At the same time, the mechanical arm 3 is started, and the mechanical arm 3 drives the round shell 311 to move back and forth. The round shell 311 drives the servo motor 312 to move, and the servo motor 312 drives the disc 313 to move. The disc 313 drives the bracket 314 to move, and the bracket 314 drives the round tube 315 to move. The round tube 315 drives the electric spray head 316 to move. At the same time, the liquid pump 318 in the glue storage box 317 is started, and the liquid pump 318 extracts glue into the hose. The hose of the pump 318 transports the glue to the electric spray head 316, and the electric spray head 316 sprays the glue, so that the mechanical arm 3 drives the electric spray head 316 to move back and forth in a U-shaped manner. When applying glue to the curved edge of the windshield, the servo motor 312 in the round shell 311 is started, and the rotating shaft of the servo motor 312 starts to rotate. The rotating shaft of the servo motor 312 drives the disc 313 to rotate, and the disc 313 drives the bracket 314 to rotate. The bracket 314 drives the circular tube 315 to rotate, and the circular tube 315 drives the electric spray head 316 to rotate, so that when the electric spray head 316 is applying glue to the curved edge of the windshield, the electric spray head 316 can rotate into an arc to apply glue to the windshield, thereby preventing the curved edge of the windshield from being difficult to apply glue when the equipment is in use, thereby avoiding the problem that the automotive parts gluing device is difficult to apply glue to the curved edge of the windshield, resulting in poor gluing effect of the equipment.

[0036] When the disc 313 drives the bracket 314 to move, the bracket 314 drives the spring rod 321 to move, the spring rod 321 drives the ball shell 322 to move, and the ball shell 322 drives the rubber ball 323 to move. Under the action of friction, the rubber ball 323 rolls on the windshield. When the disc 313 drives the bracket 314 to rotate, the bracket 314 drives the spring rod 321 to rotate, the spring rod 321 drives the ball shell 322 to rotate, and the ball shell 322 drives the rubber ball 323 to rotate, so that when the electric spray head 316 rotates into an arc, the rubber ball 323 is against the windshield, so that the electric spray head 316 can be supported by the rubber ball 323 when rotating to apply glue, thereby reducing the amplitude of the electric spray head 316, thereby avoiding the problem of distortion of glue coating caused by vibration of the electric spray head 316 when the automotive parts gluing device is applying glue to the curved edge of the windshield.

[0037] See also Figure 1-Figure 8 On the basis of the above embodiment, another embodiment of the present invention further includes a glue-proof device 4 and an anti-entanglement device 5, wherein the glue-proof device 4 is provided at the bottom of the outer wall of the spring rod 321, and the glue-proof device 4 includes a ring block 41, an inclined tube rod 42, a ring plate 43 and a ring blocking plate 44, the ring block 41 is fixed at the bottom of the outer wall of the spring rod 321, the inclined tube rod 42 is fixed at the left side of the ring block 41, the ring plate 43 is fixed at the end of the inclined tube rod 42 away from the ring block 41, and a ring blocking plate 44 is fixed on the bottom surface of the ring plate 43, and the ring plate 43 is located at the bottom of the outer wall of the electric spray head 316. During the rotation of the ring blocking plate 44, the ring blocking plate 44 blocks the glue sprayed by the electric spray head 316 from splashing, so as to avoid the glue sprayed by the electric spray head 316 from splashing when the automotive parts glue coating device is coating the curved edge of the windshield, causing the equipment to fail to coat the glue.

[0040] The anti-entanglement device 5 also includes an annular tube 56, an arc-shaped spring piece 57 and a connecting block 58. The annular tube 56 is fixed in the middle of the outer wall of the vertical rod 52, the arc-shaped spring piece 57 is embedded in the right side of the annular tube 56, and the connecting block 58 is fixed on the side of the arc-shaped spring piece 57 away from the annular tube 56. The right side of the connecting block 58 is fixedly connected to the left side of the circular tube 315. The connecting block 58 is located above the ring plate 43. Under the elastic force of the arc-shaped spring piece 57, the shaking of the vertical rod 52 during rotation is reduced, so as to avoid the automobile parts gluing device from vigorous shaking during the gluing process, resulting in inaccurate gluing of the equipment.

[0041] While the bracket 314 drives the spring rod 321 to rotate, the spring rod 321 drives the ring block 41 to rotate, the ring block 41 drives the oblique tube rod 42 to rotate, the oblique tube rod 42 drives the ring plate 43 to rotate, and the ring plate 43 drives the ring plate 44 to rotate, so that during the rotation of the ring plate 44, the ring plate 44 blocks the glue sprayed by the electric nozzle 316 from splashing, thereby preventing the glue sprayed by the electric nozzle 316 from splashing when the equipment is in use, thereby avoiding the problem of unqualified gluing caused by the glue sprayed by the electric nozzle 316 during the process of gluing the curved edge of the windshield by the automotive parts gluing device.

[0042] While the ring block 41 drives the inclined tube rod 42 to rotate, the inclined tube rod 42 drives the L-shaped rod 45 to rotate, the L-shaped rod 45 drives the U-shaped frame 46 to rotate, and the U-shaped frame 46 drives the heating plate 47, and the heating plate 47 on the U-shaped frame 46 is started. The heating plate 47 transfers heat to the ring resistance plate 44, so that during the rotation of the ring resistance plate 44, the heat of the ring resistance plate 44 is transferred to the electric spray head 316, so that there will be no solidified glue at the nozzle of the electric spray head 316, preventing the electric spray head 316 from having solidified glue at the nozzle of the electric spray head 316 when the equipment is in use, thereby avoiding the problem of solidified glue at the nozzle of the electric spray head 316 during the gluing process of the automotive parts gluing device causing poor gluing effect of the equipment.

[0043] While the L-shaped rod 45 drives the U-shaped frame 46 to rotate, the U-shaped frame 46 drives the horizontal strip 51 to rotate, the horizontal strip 51 drives the vertical rod 52 to rotate, the vertical rod 52 drives the arc plate 53 to rotate, the arc plate 53 drives the short column 54 to rotate, and the short column 54 drives the rubber pad 55 to rotate, so that the rubber pad 55 contacts the hose of the liquid pump 318 during the rotation process, allowing the rubber pad 55 to limit the hose to prevent the hose of the liquid pump 318 from being entangled on the equipment when the equipment is in use, thereby avoiding the problem of the hose of the liquid pump 318 being entangled on the equipment during the gluing process of the automotive parts gluing device causing the equipment to jam.

[0044] While the horizontal strip 51 drives the vertical rod 52 to rotate, the vertical rod 52 drives the annular tube 56 to rotate, the annular tube 56 drives the arc-shaped spring piece 57 to rotate, and the arc-shaped spring piece 57 drives the connecting block 58 to rotate. Under the elastic force of the arc-shaped spring piece 57, the shaking of the vertical rod 52 during rotation is reduced, and the equipment is prevented from shaking violently during operation, thereby avoiding the problem of inaccurate gluing caused by violent shaking of the equipment during the gluing process of the automotive parts gluing device.
