During operation, in the existing stamping and flipping device, during the process of flipping the backlight iron frame, due to the inability to conveniently discharge the backlight iron frame after stamping, the efficiency of flipping is relatively poor. After the stamping of the backlight iron frame is completed, the hydraulic cylinder 29 operates, and the hydraulic rod 30 drives the pressing plate 31 to move vertically upward. The pressing plate 31 drives the upper die 32 to move vertically upward. At this time, the stamped backlight iron frame is located in the lower die 28. By operating the stepping motor 6, the lead screw 7 is driven to rotate. The lead screw 7 drives the guide block 8 to move horizontally. The guide block 8 drives the sliding plate 9 to move horizontally. The sliding plate 9 drives the lifting plate 19 thereon to move horizontally, so that the lifting plate 19 is located directly above the backlight iron frame. Then, the clamping component on the lifting plate 19 clamps the backlight iron frame. After that, by operating the stepping motor 6 again, the lifting plate 19 drives the backlight iron frame to move horizontally, and the backlight iron frame is removed from the lower die 28, realizing the convenient discharging of the backlight iron frame. Then, by operating the first electric telescopic rod 15, the first push rod 16 thereon drives the rack 14 to move vertically downward. The rack 14 pushes the gear 12 to rotate 180°. The gear 12 drives the rotating rod 11 to rotate 180°. The rotating rod 11 drives the flipping plate 17 to flip 180°. The flipping plate 17 drives the lifting plate 19 thereon to flip 180°.

After the lifting plate 19 moves to directly above the backlight iron frame, the second electric telescopic rod 18 operates, the second push rod 34 drives the lifting plate 19 to move vertically downward, the lifting plate 19 drives the suction cups 24 to move vertically downward, the lifting plate 19 presses the suction cups 24 against the backlight iron frame, and then the vacuum pump 20 operates to evacuate the air between the suction cups 24 and the backlight iron frame. When a vacuum is formed inside the suction cups 24, the external atmospheric pressure forces the backlight iron frame to contact the suction cups 24, and the backlight iron frame is adsorbed on the suction cups 24, realizing the adsorption and clamping of the backlight iron frame by the suction cups 24. Then the second push rod 34 drives the lifting plate 19 to move vertically upward, and the lifting plate 19 drives the adsorbed backlight iron frame to move vertically upward;

[0021] When the lifting plate 19 drives the clamped backlight iron frame to turn 180°, and when the clamping component on the lifting plate 19 releases the backlight iron frame, the electromagnetic valve 26 is controlled to open through the control panel 33, and the rapid deflation of the suction cups 24 can be realized, and the backlight iron frame falls off from the suction cups 24.

[0022] Working principle: During the process of flipping the backlight iron frame by the existing stamping and flipping device, due to the inability to conveniently discharge the backlight iron frame after stamping, the efficiency of flipping is relatively poor. After the stamping of the backlight iron frame is completed, the hydraulic cylinder 29 operates, and the hydraulic rod 30 drives the pressing plate 31 to move vertically upward. The pressing plate 31 drives the upper die 32 to move vertically upward. At this time, the stamped backlight iron frame is located in the lower die 28. By the operation of the stepping motor 6, the lead screw 7 is driven to rotate. The lead screw 7 drives the guide block 8 to move horizontally. The guide block 8 drives the sliding plate 9 to move horizontally. The sliding plate 9 drives the lifting plate 19 thereon to move horizontally, so that the lifting plate 19 is located directly above the backlight iron frame. Then, the clamping component on the lifting plate 19 clamps the backlight iron frame. After that, by the operation of the stepping motor 6 again, the lifting plate 19 drives the backlight iron frame to move horizontally, and the backlight iron frame is removed from the lower die 28, realizing the convenient discharging of the backlight iron frame. Then, by the operation of the first electric telescopic rod 15, the first push rod 16 thereon drives the rack 14 to move vertically downward. The rack 14 pushes the gear 12 to rotate 180°. The gear 12 drives the rotating rod 11 to rotate 180°. The rotating rod 11 drives the flipping plate 17 to flip 180°. The flipping plate 17 drives the lifting plate 19 thereon to flip 180°. The lifting plate 19 drives the clamped backlight iron frame to flip 180°. The clamping component on the lifting plate 19 releases the backlight iron frame. The backlight iron frame is placed on the placement table 3. This structure can accurately clamp the backlight iron frame, conveniently discharge the backlight iron frame, and finally efficiently flip the backlight iron frame. After the flipping is completed, the staff can take out the iron frame for the next processing or assembly work, which is beneficial to improving the efficiency of flipping the backlight iron frame and is beneficial to improving the processing efficiency of the backlight iron frame. During the process of flipping the backlight iron frame by the existing stamping and flipping device, the clamping force of the fixture cannot be controlled, and it is easy to cause damage to the backlight iron frame due to excessive clamping force, resulting in poor protection of the device. After the lifting plate 19 moves to directly above the backlight iron frame, the second electric telescopic rod 18 operates. The second push rod 34 drives the lifting plate 19 to move vertically downward. The lifting plate 19 drives the suction cup 24 to move vertically downward. The lifting plate 19 presses the suction cup 24 on the backlight iron frame. Then, the vacuum pump 20 operates. The vacuum pump 20 evacuates the air between the suction cup 24 and the backlight iron frame. When a vacuum is formed inside the suction cup 24, the external atmospheric pressure forces the backlight iron frame to contact the suction cup 24, and the backlight iron frame is adsorbed on the suction cup 24, realizing the adsorption and clamping of the suction cup 24 on the backlight iron frame. Then, the second push rod 34 drives the lifting plate 19 to move vertically upward. The lifting plate 19 drives the adsorbed backlight iron frame to move vertically upward;

[0023] When the lifting plate 19 drives the backlight iron frame clamped thereon to flip 180°, and when the clamping component on the lifting plate 19 releases the backlight iron frame, the electromagnetic valve 26 is controlled by the control panel 33 to open, and rapid deflation of the suction cup 24 can be achieved, and the backlight iron frame falls off from the suction cup 24. This structure realizes the clamping and fixing of the backlight iron frame through the adsorption of the suction cup 24 on the backlight iron frame, avoiding damage to the backlight iron frame caused by excessive clamping force, and is beneficial to improving the protection of the backlight iron frame.
