A top frame 3 is fixedly connected to the upper end of the support beam 2. A hydraulic cylinder 4 is fixedly installed on the upper end of the top frame 3. The output end of the hydraulic cylinder 4 passes through the upper end of the top frame 3 and is fixedly connected to an upper mold mounting frame 5. Adsorption mounting frames 12 are provided on both the left and right sides of the base 1. Mounting plates 13 are movably connected to the lower ends of the adsorption mounting frames 12, the upper ends of the base 1, and the lower ends of the upper mold mounting frames 5. A lower mold 15 is fixedly connected to the upper end of the lower mounting plate 13, and an upper mold 16 is fixedly connected to the lower end of the upper mounting plate 13. Vacuum adsorption plates 17 are fixedly connected to the lower ends of the left and right mounting plates 13. Four evenly distributed insertion holes 14 are provided on the lower ends of the adsorption mounting frames 12, the upper ends of the base 1, and the lower ends of the upper mold mounting frames 5. The mounting plate 13 has a rotating groove 18. A locking groove 19 is formed on the inner wall of the rotating groove 18 near the mounting plate 13. A fixing cylinder 20 is fixedly connected to the end of the mounting plate 13 away from the locking groove 19. A fixing plate 21 is fixedly connected inside the fixing cylinder 20.

The other end of the connecting pin 22 passes through the end of the mounting plate 13 near the locking groove 19 and extends into the interior of the rotating groove 18. A pressing plate 25 is fixedly connected to the end of the connecting rod 24 away from the connecting pin 22, passes through the end of the fixing cylinder 20 away from the rotating groove 18. A movable plate 26 is fixedly connected to the outer surface of the connecting rod 24. The movable plate 26 is slidably connected to the interior of the fixing cylinder 20. A spring 27 is sleeved on the outer surface of the connecting rod 24 between the movable plate 26 and the fixing plate 21.

[0030] Furthermore, a shaping groove 1501 is provided at the upper end of the lower mold 15. The shapes of the shaping groove 1501 and the upper mold 16 can be customized according to the shape of the display back panel to be processed as needed.

[0031] Furthermore, one side of the socket 14 is an arc groove, and the other side is a rectangular groove, with the locking groove 19 spaced 90° from the rectangular groove portion of the socket 14.

[0032] Furthermore, a locking block 23 is fixedly connected to the outer surface of the connecting pin 22, and the locking block 23 is engaged inside the locking groove 19.

[0033] Furthermore, the upper mold 16, lower mold 15, and vacuum adsorption plate 17 are all fixedly connected to the mounting plate 13 of the same size, and are all fixed by the locking block 23 and locking groove 19 structure. When installing the upper mold 16, lower mold 15, and vacuum adsorption plate 17, the locking block 23 on the mounting plate 13 is aligned with the rectangular groove portion of the insertion hole 14, and then the pressing plate 25 is pushed, so that the movable plate 26 compresses the spring 27, which drives the connecting rod 24 to push the connecting pin 22 to move. When the connecting pin 22 is in contact with the inner groove of the rotating groove 18... When the parts are in contact, rotating the pressing plate 25 by 90° will make the locking block 23 align with the locking groove 19. At this time, releasing the pressing plate 25 will cause the spring force of the spring 27 to drive the locking block 23 into the locking groove 19, thereby locking the mounting plate 13.

A second servo motor 32 for driving the second lead screw 31 to rotate is fixedly installed at the upper end of the fixed bracket 9. A lifting block 11 is threadedly connected to the outer surface of the second lead screw 31. The front ends of the two adsorption mounting brackets 12 are fixedly connected to the rear ends of the two lifting blocks 11 respectively.

[0035] Furthermore, the upper end of the adsorption mounting bracket 12 is provided with a through groove 1201, which is configured as a space for the connection of the threaded interface 28 with external equipment.

[0036] Furthermore, the vacuum adsorption plate 17 has a hollow structure, and multiple adsorption holes are opened at the lower end of the vacuum adsorption plate 17. The upper end of the vacuum adsorption plate 17 is connected to a threaded interface 28. The two threaded interfaces 28 pass through the upper end of the left mounting plate 13 and the upper end of the right mounting plate 13 respectively and extend to the upper side of the left mounting plate 13 and the right mounting plate 13 respectively.

[0037] Furthermore, the threaded interface 28 is used to connect a vacuum pump. By drawing air out of the vacuum adsorption plate 17, a negative pressure can be generated at the adsorption holes of the vacuum adsorption plate 17, thereby adsorbing the back panel of the display. The shape of the lower end of the vacuum adsorption plate 17 can be designed according to the shape of the back panel of the display to improve the fit with the surface of the back panel of the display and improve the stability of the adsorption.

[0038] Furthermore, the left vacuum adsorption plate 17 is used to adsorb the display back panel to be shaped, realizing automatic feeding, and the right vacuum adsorption plate 17 is used to adsorb the shaped display back panel. In their initial positions, the two vacuum adsorption plates 17 are located on the left and right sides of the base 1, respectively. The distance between the left and right vacuum adsorption plates 17 is greater than the length of the base 1. The left side of the left vacuum adsorption plate 17 is used to set up the display back panel feeding device, and the right side of the right vacuum adsorption plate 17 is used to set up the conveying device. The feeding device and the conveying device can be... The display back panel is transported by means of a conveyor belt or robotic arm. During processing, the first servo motor 30 first drives the first lead screw 29 to rotate forward. The rotation of the first lead screw 29 will drive the slide 8 to move to the left, thereby moving the left vacuum adsorption plate 17 to directly above the feeding device. When the left vacuum adsorption plate 17 is directly above the feeding device, the right vacuum adsorption plate 17 is directly above the lower mold 15. At this time, the two second servo motors 32 drive the two second lead screws 31 to rotate, so that the two lifting blocks 11 move the two vacuum adsorption plates 17 downward. Simultaneously, the external vacuum equipment is activated. At this time, the left vacuum adsorption plate 17 will adsorb the display back panel to be shaped, while the right vacuum adsorption plate 17 will adsorb the shaped display back panel in the lower mold 15. After adsorption is completed, the second servo motor 32 drives the two lifting blocks 11 to reset, and the first servo motor 30 reverses, causing the right vacuum adsorption plate 17 to move directly above the conveying equipment. When the right vacuum adsorption plate 17 is directly above the conveying equipment, the left vacuum adsorption plate 17 is directly above the lower mold 15. At this time, the second servo motor... The first servo motor 30 drives the two vacuum adsorption plates 17 to move downward. When the vacuum adsorption plates 17 move to the appropriate position, the two vacuum adsorption plates 17 release the adsorbed display back panel. At this time, the display back panel to be shaped is placed in the shaping groove 1501. The shaped display back panel falls onto the conveying equipment and is transferred to the next process. Then, the first servo motor 30 drives the slide 8 to reset. After the slide 8 is reset, the hydraulic cylinder 4 pushes the upper mold 16 down to shape the display back panel in the shaping groove 1501. After the shaping is completed, the above process will be repeated to realize automated processing.

[0039] Working principle: In use, the first servo motor 30 first drives the first lead screw 29 to rotate forward. The rotation of the first lead screw 29 will drive the slide block 8 to move to the left, thereby moving the left vacuum adsorption plate 17 to directly above the feeding device. When the left vacuum adsorption plate 17 is directly above the feeding device, the right vacuum adsorption plate 17 is directly above the lower mold 15. At this time, the two second servo motors 32 drive the two second lead screws 31 to rotate, causing the two lifting blocks 11 to move the two vacuum adsorption plates 17 downward. At the same time, the external vacuum equipment is activated. At this time, the left vacuum adsorption plate 17 will adsorb the display back panel to be shaped, while the right vacuum adsorption plate 17 will adsorb the shaped display back panel in the lower mold 15. After adsorption is completed, the second servo motor 30 drives the two lifting blocks 11 to reset, and the first servo motor 30 drives the slide block 8 to move to the left, thereby moving the slide block 8 to the left, and the slide block 8 to the right. Motor 30 reverses, causing the right vacuum adsorption plate 17 to move directly above the conveying equipment. When the right vacuum adsorption plate 17 is directly above the conveying equipment, the left vacuum adsorption plate 17 is directly above the lower mold 15. At this time, the second servo motor 32 drives the two vacuum adsorption plates 17 to move downward. When the vacuum adsorption plates 17 move to the appropriate position, the two vacuum adsorption plates 17 release the adsorbed display back panel. At this time, the display back panel to be shaped is placed in the shaping groove 1501. The shaped display back panel falls onto the conveying equipment and is transferred to the next process. Then, the first servo motor 30 drives the slide 8 to reset. After the slide 8 resets, the hydraulic cylinder 4 pushes the upper mold 16 down to shape the display back panel in the shaping groove 1501. After the shaping is completed, the above process will be repeated to achieve automated processing.
