[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 3As shown in the embodiment of this utility model, an LED display processing and positioning device includes a base 1; a plurality of fixing plates 11 are fixedly connected to the top of the base 1; a first screw 12 is threadedly connected to the middle of the fixing plate 11; a clamping plate 13 is rotatably connected to the end of the first screw 12; a first limiting rod 14 is fixedly connected to the side wall of the clamping plate 13; the first limiting rod 14 passes through the fixing plate 11 and slides with the fixing plate 11; a plurality of sliding grooves 15 are formed on the inner side wall of the clamping plate 13; a limiting block 16 is slidably connected inside the sliding groove 15; a first spring 17 is fixedly connected between the limiting block 16 and the inner side wall of the sliding groove 15; during operation, the first screw 12 is first controlled to move the two clamping plates 13 away from each other, then the display to be processed is placed between the two clamping plates 13, and then the first screw 12 is rotated to move the two clamping plates 13 closer to each other until they contact the frame of the LED display. To achieve the positioning and clamping of the display, as the clamping plate 13 approaches the display, the limiting block 16 will first contact the display frame and compress the first spring 17. At this time, the limiting block 16 will retract into the slide groove 15. During this process, the limiting block 16 that is not in contact with the display will remain in its original position, thereby limiting the position of the display. At this time, when the clamping plate 13 squeezes the display, the display is less likely to tilt between the two clamping plates 13. After the display is processed, the first screw 12 is controlled to move the two clamping plates 13 away from each other. At this time, the clamping plate 13 is disengaged from the display, thereby releasing the display and completing the processing and positioning of the LED display screen. By providing multiple limiting blocks 16 in the middle of the clamping plate 13 to cooperate with each other, the clamping plate 13 can achieve a positioning effect even for thinner displays during the clamping process, reducing the tilting problem of the display screen when it is clamped and improving the processing and positioning stability.

[0026] like Figure 3 As shown, an elastic band 2 is provided between adjacent limiting blocks 16; the end of the elastic band 2 is fixedly connected to the limiting block 16; during operation, after the limiting block 16 contacts the display screen, the elastic band 2 can contact the boundary of the display screen and be tightened on the frame of the display screen to achieve stability of the display screen when it is positioned; by adding multiple elastic bands 2, the contact area can be increased when the limiting block 16 contacts the display screen, the friction can be improved, and the problem of loosening and shaking of the display screen during the clamping and positioning process can be further reduced, thereby further improving the positioning stability of the display screen.

[0027] like Figure 5As shown, a second limiting rod 3 is slidably connected to the bottom of the clamping plate 13; a pull rod 31 is fixedly connected to the bottom end of the second limiting rod 3; a second spring 32 is sleeved in the middle of the second limiting rod 3; one end of the second spring 32 is fixedly connected to the pull rod 31, and the other end is fixedly connected to the clamping plate 13; a top plate 33 is fixedly connected to the top of the second limiting rod 3; multiple suction cups 34 are fixedly connected to the top of the top plate 33; during operation, as the clamping plate 13 moves closer to the display screen, the pull rod 31 needs to be pulled down. At this time, the second limiting rod 3 and the top plate 33 will descend synchronously, simultaneously stretching the second spring 32. After the display screen is clamped and positioned by the two clamping plates 13, it is released. Pull rod 31 can move upward under the contraction of the second spring 32. At this time, the suction cup 34 on the top of the top plate 33 will contact the bottom of the display screen to achieve adsorption of the bottom of the display screen. After the display screen is processed, pull rod 31 to make the second limit rod 3, the top plate 33 and the suction cup 34 descend synchronously. At this time, the suction cup 34 will disengage from the display screen. By providing a movable suction cup 34 inside the clamping plate 13, the display screen can be adsorbed from the bottom when the clamping plate 13 clamps and positions the display screen. Without damaging the top panel of the display screen, the positioning effect of the display screen between the clamping plates 13 is further stabilized.

[0028] like Figure 6 As shown, a plurality of tower-shaped springs 4 are fixedly connected to the top of the top plate 33; a top ring 41 is fixedly connected to the top of the tower-shaped springs 4; the top ring 41 is located between the suction cup 34 and the top plate 33; during operation, when the suction cup 34 is attached to the bottom of the display screen, the top ring 41 can contact the boundary of the suction cup 34 during the deformation of the suction cup 34, thereby squeezing the boundary of the suction cup 34 and making the adhesion and sealing between the suction cup 34 and the display screen better.

[0029] like Figure 4 As shown, the top of the clamping plate 13 is connected to a second screw 5 via a thread; the bottom of the second screw 5 is rotatably connected to a pressure plate 51; the top of the pressure plate 51 is fixedly connected to a third limiting rod 52; the third limiting rod 52 passes through the clamping plate 13 and slides with the clamping plate 13; a rubber pad 53 is fixedly connected to the bottom of the pressure plate 51; the bottom of the rubber pad 53 is serrated; during operation, when the display screen is positioned in the middle of the clamping plate 13, the second screw 5 can be rotated to move the pressure plate 51 downwards until the rubber pad 53 contacts the top of the display screen, at which point the rotation of the second screw 5 stops. At this time, the rubber pad 53 only contacts the display screen but does not apply pressure to the display screen. The purpose of this operation is to limit the top of the display screen with the pressure plate 51 and the rubber pad 53, further reducing the problem of the display screen tilting upwards.

[0030] like Figure 4As shown, a sponge pad 6 is fixed to the bottom of the pressure plate 51; the sponge pad 6 is wrapped around the outside of the rubber pad 53; during operation, by adding a sponge pad 6 to the bottom of the pressure plate 51, when the rubber pad 53 is close to the top of the LED display screen, the sponge pad 6 contacts the top of the display screen, reducing the scratches caused by direct contact between the rubber pad 53 and the top of the display screen.

[0031] The working principle is as follows: First, the first screw 12 is controlled to move the two clamping plates 13 away from each other. Then, the display to be processed is placed between the two clamping plates 13. Next, the first screw 12 is rotated to move the two clamping plates 13 closer together until they contact the frame of the LED display, thus achieving positioning and clamping of the display. As the clamping plates 13 approach the display, the limiting block 16 will first contact the display frame, compressing the first spring 17. At this time, the limiting block 16 will retract into the slide groove 15. During this process, the limiting block 16 that is not in contact with the display will remain in its original position, thus limiting the position of the display. At this time, when the clamping plates 13 squeeze the display, the display is less likely to tilt between the two clamping plates 13. After the display is processed, the first screw 12 is controlled to move the two clamping plates 13 away from each other. At this time, the clamping plates 13 are disengaged from the display, thus releasing the display and completing the processing and positioning of the LED display screen. After contact with the display screen, the elastic band 2 can contact the edge of the display screen and beaded on the frame of the display screen to achieve stability when the display screen is positioned. As the clamping plate 13 moves closer to the display screen, the pull rod 31 needs to be pulled down. At this time, the second limiting rod 3 and the top plate 33 will descend synchronously, and the second spring 32 will be stretched. After the display screen is clamped and positioned by the two clamping plates 13, the pull rod 31 is released. At this time, the pull rod 31 can move upward under the contraction of the second spring 32. At this time, the suction cup 34 on the top of the top plate 33 will contact the bottom of the display screen to achieve adsorption of the bottom of the display screen. After the display screen is processed, the pull rod 31 is pulled to make the second limiting rod 3, the top plate 33 and the suction cup 34 descend synchronously. At this time, the suction cup 34 is separated from the contact with the display screen. When the suction cup 34 is attached to the bottom of the display screen, during the deformation of the suction cup 34, the top ring 41 can contact the edge of the suction cup 34 to squeeze the edge of the suction cup 34, so that the adhesion and sealing between the suction cup 34 and the display screen is better. When the display screen is positioned in the middle of the clamping plate 13, the second screw 5 can be rotated to move the pressure plate 51 downwards until the rubber pad 53 contacts the top of the display screen. Then, the rotation of the second screw 5 is stopped. At this time, the rubber pad 53 only contacts the display screen but does not apply pressure to the display screen. The purpose of this operation is to limit the top of the display screen by the pressure plate 51 and the rubber pad 53. By adding a sponge pad 6 at the bottom of the pressure plate 51, the sponge pad 6 can contact the top of the display screen when the rubber pad 53 is close to the top of the LED display screen, reducing the scratches caused by direct contact between the rubber pad 53 and the top of the display screen.
