[0034] During the implementation of this embodiment, the LED display back panel to be stamped is placed in the lower mold 6. Through the control of the control box 3, the lower pressing component 4 drives the upper mold 5 to perform a stamping operation on the LED display back panel. After the stamping is completed, the upper mold 5 is away from the LED display back panel. At this time, the demoulding component 7 is used to clean the debris and oil stains formed on the upper part of the outer surface of the LED display back panel due to stamping, and then the demoulding component 7 is used to eject and adsorb the LED display back panel, so that the demoulding component 7 is separated from the lower mold 6. Subsequently, before the next stamping operation, the spraying component 8 is used to spray the release agent on the inner surface of the lower mold 6, thereby facilitating the demoulding operation of the stamped LED display back panel.

[0038] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 In this embodiment, the driving mechanism 73 includes a double-axis motor 733 fixedly connected to the lower part of the inner surface of the rectangular cover 79, the left end output end of the double-axis motor 733 is fixedly connected to a rotating rod 734 through a coupling, the front end of the rectangular plate 71 is symmetrically fixedly connected to a fixed block 735, the inner surfaces of the two fixed blocks 735 are rotatably connected to a transmission rod 737, the outer surface of the rotating rod 734 is fixedly connected to a gear belt group 736 fixedly connected to the middle part of the outer surface of the transmission rod 737, the outer surface of the transmission rod 737 is symmetrically fixedly connected to a one-way bearing 738, the rear part of the inner surface of the two slide grooves 72 passes through and extends to the front end of the rectangular plate 71 and is rotatably connected to a screw rod 731, the outer surfaces of the two screw rods 731 are fixedly connected to a bevel gear group 739 fixedly connected to the outer surface of the one-way bearing 738, and the inner surfaces of the two slide grooves 72 are slidably connected to a slider 732 slidably connected to the outer surface of the screw rod 731.

[0039] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 In this embodiment, the cleaning mechanism 74 includes a connecting block 741 fixedly connected to the upper end of the left slider 732, the upper end of the connecting block 741 is fixedly connected to a groove plate 742, and a sponge block 743 is pasted on the upper inner surface of the groove plate 742.

[0040] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 In this embodiment, the collecting mechanism 78 includes a slot 781 opened at the upper end of the rectangular plate 71, the inner surface of the slot 781 is snapped with a collecting frame 782, and the inner surface of the collecting frame 782 is fixedly connected with a filter screen 783.

[0041] During the implementation process, the left end output end of the dual-axis motor 733 is started to drive the rotating rod 734 to rotate forward, and the transmission rod 737 is driven to rotate under the cooperation of the gear belt group 736. At this time, under the action of the one-way bearing 738 located on the left, the bevel gear group 739 located on the left is driven to move, thereby causing the screw rod 731 located on the left to rotate, and under the action of the sliding connection between the slider 732 and the screw rod 731, the groove plate 742 on the connecting block 741 is driven to move forward, so that the sponge block 743 on the groove plate 742 can be sponged to clean the debris and oil stains generated on the back panel of the LED display after stamping. At the same time, the cleaned debris and oil stains will enter the collection frame 782 under the action of gravity, and be separated into solid and liquid through the filter net 783, so that no debris is generated on the outer surface of the back panel of the LED display, which is convenient for subsequent demolding operations.

[0042] The gear belt assembly 736 mentioned above is composed of two gears and a toothed belt.

[0043] The bevel gear set 739 mentioned above is composed of two bevel gears.

[0044] The slider 732 and the screw rod 731 mentioned above constitute a ball screw mechanism in the prior art.

[0045] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the adsorption mechanism 75 includes a square rod 751 fixedly connected to the middle part of the upper end of the right slider 732, an L-shaped rod 752 is slidably connected to the outer surface of the square rod 751, the upper end of the rectangular plate 71 is located at the right slide groove 72 and is symmetrically fixedly connected to a guide plate 756, the lower end of the L-shaped rod 752 is symmetrically fixedly installed with a roller 755, the middle part of the upper end of the square rod 751 is fixedly connected to a spring 753 fixedly connected to the upper part of the inner surface of the L-shaped rod 752 in the vertical direction, and the lower end of the L-shaped rod 752 in the horizontal direction is linearly distributed and fixedly connected to a plurality of suction cups 754 connected to the horizontal inner surface of the L-shaped rod 752.

[0046] The gear train 736 then rotates the transmission rod 737, and the bevel gear set 739 on the right side is driven to move, thereby causing the screw rod 731 on the right side to rotate, causing the slider 732 on the right side to slide on the inner surface of the slide groove 72, thereby driving the square rod 751 to move backward, thereby driving the L-shaped rod 752 to move backward, causing the roller 755 at the lower end of the L-shaped rod 752 to roll on the upper end of the guide plate 756. When the roller 755 moves to the groove at the upper end of the guide plate 756, due to the height change of the upper end of the guide plate 756, the L-shaped rod 752 is pulled down as a whole under the tensile reaction of the spring 753 of gravity, so that the height of the suction cup 754 can be reduced.

[0047] The one-way bearing 738 mentioned above is a mature one-way rotating part in the prior art. The present solution utilizes its function of being able to rotate freely in one direction and being locked in the other direction. In the present solution, it is only necessary to satisfy that the locking directions of the one-way bearings 738 on the left and right are opposite, and its structure and principle will not be elaborated further.

[0048] The L-shaped rod 752 mentioned above is located at the front upper end of the guide plate 756 in the initial state.

[0049] The spring 753 mentioned above is in a stretched deformation state in the initial state.

[0050] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11In this embodiment, the ejection mechanism 77 includes an inverted T-shaped groove 771 that penetrates the middle side of the left part of the inner surface of the right slide groove 72 and extends to the lower part of the inner surface of the placement groove 710. A rectangular hole block 772 is fixedly connected to the inner surface of the inverted T-shaped groove 771. A rectangular rod 774 is slidably connected to the inner surface of the rectangular hole block 772. An inclined surface extrusion block 1 773 is fixedly connected to the rear end of the right slider 732. An inclined surface extrusion block 2 775 is fixedly connected to the right end of the rectangular rod 774. An inclined surface extrusion block 3 777 that is slidably connected to the inner surface of the inverted T-shaped groove 771 in the horizontal direction is fixedly connected to the left end of the rectangular rod 774. A spring 3 is sleeved on the outer surface of the rectangular rod 774. 76, two ends of spring three 776 are fixedly connected to the right end of rectangular hole block 772 and the left end of inclined surface extrusion block two 775 respectively, the vertical inner surface of inverted T-shaped groove 771 is slidably connected with a slide bar 778, the lower end of the slide bar 778 is fixedly connected with an inclined surface extrusion block four 7710 slidably connected with the vertical inner surface of inverted T-shaped groove 771, the upper end of the slide bar 778 is fixedly connected with an ejection block 779 matched with the size and shape of the inner surface of the placement groove 710, the outer surface of the slide bar 778 is sleeved with a spring four 7711, and the two ends of the spring four 7711 are fixedly connected to the upper part of the vertical inner surface of the inverted T-shaped groove 771 and the upper end of the inclined surface extrusion block four 7710 respectively.

[0051] When the slider 732 on the right drives the L-shaped rod 752 to move backward, the inclined surface extrusion block 1 773 will also move with the slider 732. When the inclined surface extrusion block 1 773 moves to the inclined surface extrusion block 2 775, under the action of the inclined surface, the inclined surface extrusion block 1 773 will squeeze and push the inclined surface extrusion block 2 775 to slide to the left on the inner surface of the inverted T-shaped groove 771, push the rectangular rod 774 to slide on the inner surface of the rectangular hole block 772, and push the inclined surface extrusion block 3 777 to move to the left. At the same time, the spring 3 776 is in a compressed state. Since the inclined surface extrusion block 3 777 moves to the left, it will squeeze the inclined surface extrusion block 4 7710 to move upward, and then push the ejection block 779 on the slide bar 778 to move upward, so that the spring 4 7711 is in a compressed state, so that the ejection block 779 will eject the stamped LED display back panel from the lower mold 6, and can make the upper end of the LED display back panel close to the lower end of the suction cup 754.

[0052] Secondly, when the inclined extrusion block 1 773 moves away from the inclined extrusion block 2 775, the inclined extrusion block 2 775 will be reset under the compression reaction of the spring 3 776, so that the inclined extrusion block 3 777 moves away from the inclined extrusion block 4 7710, so that the inclined extrusion block 4 7710 moves downward under the action of the gravity of the spring 4 7711, thereby driving the ejection block 779 to re-enter the placement groove 710.

[0053] For further information, see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 In this embodiment, the suction mechanism 76 includes a limiting mechanism 1 761 fixedly connected to the upper right end of the L-shaped rod 752, a limiting mechanism 2 762 fixedly connected to the front right end of the rectangular plate 71, a spring 2 763 fixedly connected to the left part of the inner surface of the L-shaped rod 752 in the horizontal direction, a piston 1 764 fixedly connected to the inner surface of the L-shaped rod 752 in the horizontal direction on the right end of the spring 2 763, a rotating rod 2 767 rotatably connected to the rectangular cover 79 is fixedly connected to the right end of the output end of the dual-axis motor 733 through a coupling, a retractable wheel 766 is fixedly connected to the right part of the outer surface of the rotating rod 2 767, a pull rope 765 is wound around the outer surface of the retractable wheel 766, one end of the pull rope 765 is fixedly connected to the middle part of the right end of the piston 1 764, and the outer surface of the pull rope 765 is slidably connected to the L-shaped rod 752.

[0054] During the implementation process, after the lower end of the suction cup 754 is tightly attached to the upper end of the back panel of the LED display screen, the right end output end of the dual-axis motor 733 is started to rotate to drive the rotating rod 2 767 to rotate. Since the retracting wheel 766 is fixedly connected to the rotating rod 2 767, the retracting wheel 766 rotates, driving the pull rope 765 to tighten the operation, and under the action of the limiting mechanism 1 761 and the limiting mechanism 2 762, the pull rope 765 can smoothly pull the piston 1 764 to the right on the horizontal inner surface of the L-shaped rod 752, and make the spring 2 763 in a stretched state, thereby generating negative pressure on the horizontal inner surface of the L-shaped rod 752, and generating negative pressure inside the suction cup 754, so that the LED display back panel that can be processed and stamped can be adsorbed.

[0055] Secondly, after adsorption, the driving mechanism 73 drives the screw rod 731 located on the right to rotate, and then the slider 732 can be driven to move forward. Under the action of the guide plate 756, the position of the L-shaped rod 752 is lifted again, so that the back panel of the LED display can be away from the lower mold 6. Through the reverse rotation of the retractable wheel 766, the pull rope 765 is loosened, and then the piston 1 764 is reset under the tensile reaction force of the spring 2 763, so that the suction cup 754 no longer generates negative pressure, and the back panel of the LED display is no longer adsorbed and fixed.

[0056] The height of the lower end of the LED display back panel after adsorption is higher than the height of the upper end of the groove plate 742.

[0057] The dual-axis motor 733 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes it to rotate independently on both sides, and the number of positive and negative rotations on both sides can be adjusted and controlled separately, and it can stop in time after rotating to the set number of circles.

[0058] The above-mentioned limiting mechanism 1 761 and limiting mechanism 2 762 are both composed of two limiting wheels and a concave plate, which can be used to limit the position of the pull rope 765 to prevent the pull rope 765 from getting stuck.

[0059] Embodiment 2: Based on Embodiment 1, this embodiment further includes a spraying component 8 for spraying a release agent on the lower mold 6 after demoulding, so as to achieve the purpose of spraying a release agent on the lower mold 6 after demoulding.

[0060] Specifically, in order to spray the release agent on the lower mold 6 after demoulding, refer to Figure 3 , Figure 5 , Figure 7 and Fig.12 In this embodiment, the spraying assembly 8 includes a hollow block 81 fixedly connected to the left end of the rectangular plate 71, a piston 2 83 is slidably connected to the inner surface of the hollow block 81, a connecting rod 82 fixedly connected to the left end of the connecting block 741 is fixedly connected to the middle part of the front end of the piston 2 83, and the outer surface of the connecting rod 82 is slidably connected to the hollow block 81, and a one-way valve 1 85 is fixedly installed at the rear part of the upper end of the hollow block 81 and extends to the upper part of the inner surface of the hollow block 81, and a connecting hose 87 is fixedly connected to the upper end of the one-way valve 1 85, and a connecting hose 87 is fixedly connected to the lower part of the outer surface of the connecting hose 87. A placement box 84 is fixedly connected to the rear end of the hollow block 81 and the left end of the rectangular plate 71, and a one-way valve 2 86 is fixedly installed on the lower side of the front inner surface of the placement box 84. A circular ring block 89 with an inner surface diameter larger than the outer surface diameter of the connecting hose 87 is fixedly connected at the rear end of the groove plate 742.

[0061] During the implementation process, when the connecting block 741 in the cleaning mechanism 74 moves forward, the connecting block 741 will drive the piston 2 83 on the connecting rod 82 to move forward on the inner surface of the hollow block 81, so that the inner surface of the hollow block 81 generates negative pressure, and the demoulding agent placed in the placement box 84 is sucked into the inner cavity of the hollow block 81 through the one-way valve 2 86. When the connecting block 741 moves backward, the connecting rod 82 will drive the piston 2 83 to move backward on the inner surface of the hollow block 81, so that the piston 2 83 squeezes the demoulding agent through the one-way valve 1 85 into the inside of the connecting hose 87, and in the process of moving backward, the demoulding agent is sprayed on the inside of the lower mold 6 through the nozzle 88 to prepare for the next stamping and demolding.

[0062] The one-way valve 1 85 and the one-way valve 2 86 mentioned above are mature control devices and mature control means in the prior art. This solution uses them to control the movement direction of the fluid, and their structure and principle will not be explained again.

[0063] The annular block 89 mentioned above can limit the position of the connecting hose 87 in this solution.

[0064] Working process: when in use, the driving mechanism 73 drives the movement of the slider 732 on the left to make the sponge block 743 in the cleaning mechanism 74 move forward, and the outer surface of the stamped LED display back panel is cleaned during the movement, and the cleaned debris is collected by the collecting mechanism 78. Secondly, the driving mechanism 73 drives the slider 732 on the right to move, so that the adsorption mechanism 75 moves, and when it moves to the set position, the ejection mechanism 77 ejects the LED display back panel from the lower mold 6, and then cooperates with the suction mechanism 76 to make the suction cup 754 in the adsorption mechanism 75 adsorb the LED display back panel and transport it forward, so that the LED display back panel is away from the lower mold 6, and again under the action of the suction mechanism 76, the LED display back panel can be separated from the suction cup 754, and then through the backward movement of the cleaning mechanism 74, the piston 2 83 squeezes the release agent in the hollow block 81 and sprays it into the lower mold 6 through the nozzle 88 on the connecting hose 87, so as to prepare for the next stamping and demolding.
