[0016] (III) Beneficial Effects

[0017] This invention provides a display positioning pressure plate fixture. It has the following advantages:

[0018] 1. This invention, by setting up a sliding rod, a connecting base plate, a protective frame, a first limiting block, a sliding groove, a conical block, a slider, and a rubber pad, allows the upper pressure plate to press the flexible screen as it moves downward, while simultaneously squeezing the conical block. This causes the rubber pad at the bottom of the conical block to pre-press the flexible screen, and the rubber pads on both sides move slowly from the middle to both sides at the same time. This helps the flexible screen expel air bubbles during the pressing process and improves the installation accuracy of the flexible screen.

[0019] 2. In this invention, by setting up a rubber pad, a collection box and a cleaning plate, when the conical block moves under the action of the upper pressure plate, the rubber pad will clean the particles adsorbed on the surface of the flexible screen, and at the same time, the cleaning plate will clean the particles adsorbed on the lower surface of the upper pressure plate under the action of the connecting component, so as to prevent the flexible screen from being crushed by the presence of particles during the pressing process of the upper pressure plate.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0031] like Figure 1-9As shown, this embodiment of the invention provides a display positioning pressure plate fixture, including a worktable 1. Columns 2 are fixedly connected to the four corners of the top of the worktable 1. A top plate 3 is slidably connected to the column 2. A connecting column 4 is fixedly connected to the middle of the bottom of the top plate 3. An upper pressure plate 5 is fixedly connected to the bottom end of the connecting column 4. A third limiting block 23 is fixedly connected to the top of the column 2. A fifth spring 22 is sleeved on the circumferential surface of the column 2. The fifth spring 22 mainly lifts the top plate 3 and the components on the top plate 3. A pressure rod 24 is fixedly connected to the front side wall of the top plate 3. The pressure rod 24 is mainly used to control the downward movement of the top plate 3.

[0032] A sliding rod 7 is slidably connected to the top plate 3, and a connecting base plate 8 is fixedly connected to the bottom end of the sliding rod 7. The sliding rod 7 and the connecting base plate 8 are mainly used to limit the movement of the protective frame 9. The protective frame 9 is located below the top plate 3, and the connecting base plate 8 is fixedly connected to the protective frame 9. The protective frame 9 can play a protective role during the pressing process. A groove 11 is provided on the inner wall of the protective frame 9. Two conical blocks 12 are provided inside the protective frame 9, and the two conical blocks 12 are arranged symmetrically from left to right. A slider 13 is fixedly connected to the front and rear side walls of the conical blocks 12, and the slider 13 is slidably connected inside the groove 11. The groove 11 and the slider 13 are mainly used to limit the movement of the conical blocks 12. Rubber pads 14 are fixedly connected to the bottom of each of the two conical blocks 12. By setting two conical blocks 12, it is convenient for the upper pressure plate 5 to move down and press the flexible screen. During this process, the conical blocks 12 drive the rubber pads 14 to move from the middle of the flexible screen to both sides, realizing the pre-pressing operation of the flexible screen. This helps to expel air bubbles and improve the installation accuracy of the flexible screen. In addition, the rubber pads 14 will clean the particles adsorbed on the surface of the flexible screen during the movement, preventing the flexible screen from being crushed during the pressing process of the upper pressure plate 5. A reset component 15 is set between the conical blocks 12 and the protective frame 9. When the upper pressure plate 5 moves up, the two conical blocks 12 return to their initial positions under the action of the reset component 15.

[0033] The reset assembly 15 includes a guide rod 151, a second limiting block 152, and a second spring 153. The guide rod 151 is fixedly connected to the side wall of the conical block 12 and is slidably connected to the protective frame 9. The second limiting block 152 is fixedly connected to the other end of the guide rod 151. The second spring 153 is sleeved on the guide rod 151. When the upper pressure plate 5 presses the two conical blocks 12 and forces the two conical blocks 12 to move to both sides, the second spring 153 is compressed.

[0034] Two collection boxes 17 are provided below the upper pressure plate 5. The collection boxes 17 mainly collect the particles cleaned by the cleaning plate 18 to prevent the particles from falling. After a period of use, the staff can use a high-pressure air gun to clean the particles inside the collection boxes 17. The top of the collection box 17 is fixedly connected to the cleaning plate 18, and the cleaning plate 18 is in contact with the bottom of the upper pressure plate 5. Both collection boxes 17 are connected to two conical blocks 12 through the connecting component 19. The bottom left and right edges of the upper pressure plate 5 are provided with storage slots 6. The storage slots 6 are mainly used to store the collection boxes 17 and the cleaning plate 18 to prevent the collection boxes 17 and the cleaning plate 18 from affecting the upper pressure plate 5's pressing operation on the flexible screen. The setting of the connecting component 19 makes it easy for the two conical blocks 12 to move the collection boxes 17 and the cleaning plate 18 when they move, cleaning the particles adsorbed on the lower surface of the upper pressure plate 5, and preventing the upper pressure plate 5 from crushing the flexible screen due to the presence of particles during the pressing process.

[0035] The connecting assembly 19 includes a mounting plate 191, a telescopic rod 192, a first sliding hole 193, a connecting block 194, a first connecting cylinder 195, a first movable cavity 196, a first sliding plate 197, a first connecting rod 198, a third spring 199, a connecting plate 1910, a second connecting cylinder 1911, a second movable cavity 1912, a second sliding plate 1913, a second connecting rod 1914, a fourth spring 1915, and a second sliding hole 1916. The arrangement of the first connecting cylinder 195, the first movable cavity 196, the first sliding plate 197, the first connecting rod 198, and the third spring 199 provides compensation for the movement of the cleaning plate 18, because the distance the conical block 12 moves is greater than the distance the cleaning plate 18 moves. When the cleaning plate 18 enters the storage groove 6, the cone block 12 will move. At this time, the first sliding plate 197 will slide in the first movable cavity 196, and the third spring 199 will be compressed. The second connecting cylinder 1911, the second movable cavity 1912, the second sliding plate 1913, the second connecting rod 1914, and the fourth spring 1915 are mainly designed to use the elastic force of the fourth spring 1915 to control the cleaning plate 18 to always be in contact with the upper pressure plate 5. In addition, when the cleaning plate 18 moves to the position of the storage groove 6, the cleaning plate 18 is pulled into the storage groove 6 under the action of the fourth spring 1915. The inner wall of the storage groove 6 is inclined, which makes it convenient for the cleaning plate 18 to be pushed out from the inside of the storage groove 6 later.

[0036] Mounting plate 191 is fixedly connected to the side wall of conical block 12. Telescopic rod 192 is fixedly connected to the top of mounting plate 191. First sliding hole 193 is provided at the top of top plate 3.

First sliding plate 197 is slidably connected inside the first movable cavity 196. First connecting rod 198 is fixedly connected to the side wall of first sliding plate 197. Third spring 199 is sleeved on first connecting rod 198, and third spring 199 is located inside the first movable cavity 196. The connecting plate 1910 is fixedly connected to the other end of the first connecting rod 198, the second connecting cylinder 1911 is fixedly connected to the bottom of the connecting plate 1910, the second movable cavity 1912 is disposed inside the second connecting cylinder 1911, the second sliding plate 1913 is slidably connected inside the second movable cavity 1912, the second connecting rod 1914 is fixedly connected to the bottom of the second sliding plate 1913, and the bottom end of the second connecting rod 1914 is fixedly connected to the collection box 17, the fourth spring 1915 is sleeved on the second connecting rod 1914, and the fourth spring 1915 is located inside the second movable cavity 1912, the second sliding hole 1916 is disposed on the top of the top plate 3, and the second connecting cylinder 1911 is slidably connected inside the second sliding hole 1916;

[0037] A placement slot 20 is provided at the top center of the workbench 1. The placement slot 20 is used to place the monitor and the flexible screen to be assembled. A clamping assembly 21 is provided at the bottom of the workbench 1. The clamping assembly 21 is mainly used to clamp and position the placed monitor and flexible screen. The clamping assembly 21 includes a moving slot 211, a side plate 212, a two-way screw 213, a knob 214, and a moving clamping block 215. There are two moving slots 211, which are located at the top of the workbench 1 and are symmetrically arranged. On the left and right sides of the placement slot 20, there are two side plates 212. The side plates 212 are fixedly connected to the bottom of the workbench 1, and the two side plates 212 are symmetrically arranged on the left and right sides of the two moving slots 211. The bidirectional screw 213 is rotatably connected to the two side plates 212. The knob 214 is fixedly connected to the right end of the bidirectional screw 213. There are two moving clamps 215. The two moving clamps 215 are slidably connected to the inside of the two moving slots 211 respectively. The moving clamps 215 are threadedly connected to the bidirectional screw 213.

[0038] The top of the connecting column 4 is fixedly connected to the first limiting block 10, and the circumferential surface of the connecting column 4 is fitted with the first spring 16. When the protective frame 9 contacts the worktable 1, the top plate 3 will continue to move down. At this time, the first spring 16 is compressed, which makes the protective frame 9 stable. There are two connecting base plates 8, and the two connecting base plates 8 are symmetrically arranged on the front and rear sides of the protective frame 9. There are four connecting columns 4, four first limiting blocks 10 and four first springs 16, and they are arranged in pairs, corresponding to the two connecting base plates 8 respectively.

[0039] Working principle: First, the monitor and flexible screen are placed inside the placement slot 20. Then, the operator controls the top plate 3 to move down using the pressure rod 24. The protective frame 9 first contacts the workbench 1, and at the same time, the rubber pad 14 presses down on the flexible screen. As the top plate 3 continues to move down, the upper pressure plate 5 squeezes the conical block 12, forcing the conical block 12 to move the rubber pad 14. The rubber pad 14 also performs a pre-pressing operation on the flexible screen and can clean the particles on the surface of the flexible screen. While the conical block 12 is moving, the cleaning plate 18, under the action of the connecting component 19, cleans the particles adsorbed at the bottom of the upper pressure plate 5. Before the upper pressure plate 5 presses down on the flexible screen, the cleaning plate 18 enters the storage slot 6. After pressing is completed, the pressure rod 24 is released, and the top plate 3 rises under the action of the fifth spring 22. At the same time, the conical block 12 and the cleaning plate 18 gradually return to their original positions, making it easy to perform the next pressing operation.
