Description

Technical Field

[0001] This utility model relates to the field of holographic screen assembly, specifically a holographic screen assembly sealing and curing device. Background Technology

[0002] Holographic displays are a type of display used in digital clocks and many portable computers. Holographic displays use two polarized materials with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to rearrange, making it impossible for light to pass through.

[0003] In the encapsulation of holographic screens, an adhesive curing device is required. However, existing holographic screen encapsulation and curing devices simply place the holographic screen on top of the processing table and do not have the function of limiting the position of the holographic screen. During processing, vibration may occur, causing the holographic screen to shake, which will affect the position and quality of the adhesive dispensing.

[0004] Therefore, a holographic screen assembly, sealing, and curing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a holographic screen assembly sealing and curing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A holographic screen assembly sealing and curing device of this utility model includes a base; a bracket is fixedly connected to the top of the base, a dispensing device is slidably connected to the inner side of the bracket, a UV lamp is provided on the side of the dispensing device, a first sliding groove is opened inside the base, a first motor is fixedly connected to the side of the base, a stud is fixedly connected to the output end of the first motor, the stud is rotatably connected to the first sliding groove, a movable frame is threadedly connected to the surface of the stud, the movable frame is slidably connected to the first sliding groove, a second motor is fixedly connected to the top of the movable frame, a positive and negative threaded screw is fixedly connected to the output end of the second motor, a clamping plate is threadedly connected to the surface of the positive and negative threaded screw, and the clamping plate is slidably connected to the movable frame; this step moves the movable frame by the stud, which can adjust the position of the clamping plates on both sides to reinforce the screen, and moves the clamping plate towards the middle by the positive and negative threaded screw, so that the clamping plate can clamp and limit screens of different sizes, increasing the applicable range of positioning the screen on the top of the base, and making the screen more stable during dispensing.

[0007] Preferably, an electric push rod is fixedly connected to the side of the clamping plate, and a pressure plate is fixedly connected to the moving end of the electric push rod. The pressure plate is slidably connected to the clamping plate. In this step, the electric push rod can drive the pressure plate to press down on the frame and screen after they are bonded together, pressing the screen and the frame tightly and improving their tightness.

[0008] Preferably, the base has a first groove on both the front and rear sides, and the clamping plate has a second groove on the top. This step increases the distance the clamping plate can move towards the center through the first groove, and increases the distance the pressure plate can move downward through the second groove, thereby improving the applicability of the clamping plate and pressure plate in limiting the screen and frame.

[0009] Preferably, the bottom of the base is provided with a second sliding groove, which is slidably connected to the movable frame; this step can limit the two sides of the movable frame through the second sliding groove, thereby increasing the stability of the movable frame when it moves.

[0010] Preferably, a reinforcing block is fixedly connected to the top of the positive and negative threaded screws, and one end of the clamping plate is rotatably connected to the reinforcing block; in this step, the reinforcing block can reinforce one end of the movable frame and limit the distance that the electric push rod moves outward. When the electric push rod moves outward and the surface contacts the reinforcing block, the clamping plate stops moving outward.

[0011] Preferably, a plurality of rollers are rotatably connected to the inner side of the first groove; in this step, when the inner side of the clamping plate contacts the surface of the rollers, the moving frame then drives the clamping plate to move horizontally inside the first groove. At this time, the inner side of the clamping plate drives the rollers to rotate, which can prevent the clamping plate from moving and causing wear when it is in contact with the inner side of the first groove.

[0012] The advantages of this utility model are: 1. The holographic screen assembly sealing and curing device of this utility model moves the movable frame by means of studs, and can adjust the position of the two side clamps for screen reinforcement. The clamps are moved towards the middle by means of positive and negative thread screws, so that the clamps can clamp and limit screens of different sizes, increase the applicable range of positioning the screen on the top of the base, and make the screen more stable when applying glue.

[0013] 2. The holographic screen assembly sealing and curing device of this utility model can drive the pressure plate to press down on the frame and screen after they are bonded together by an electric push rod, so as to press the screen and the frame tightly and improve the tightness of the two.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 5As shown, a holographic screen assembly and sealing curing device includes a base 1; a bracket 12 is fixedly connected to the top of the base 1, a dispensing device 13 is slidably connected to the inner side of the bracket 12, a UV lamp 14 is provided on the side of the dispensing device 13, a first groove 15 is formed inside the base 1, a first motor 16 is fixedly connected to the side of the base 1, a stud 17 is fixedly connected to the output end of the first motor 16, the stud 17 is rotatably connected to the first groove 15, and a movable frame 18 is threadedly connected to the surface of the stud 17. The movable frame 18 is slidably connected to the first slide groove 15. A second motor 19 is fixedly connected to the top of the movable frame 18. A threaded screw 110 is fixedly connected to the output end of the second motor 19. A clamping plate 111 is threadedly connected to the surface of the threaded screw 110. The clamping plate 111 is slidably connected to the movable frame 18. During operation, the first motor 16 drives the stud 17 to rotate, which in turn drives the movable frame 18 to move inside the first slide groove 15. The movable frame 18 then drives the second motor 19 to move, adjusting the clamping plates 111 on both sides. The position allows staff to easily place the screen on top of the base 1, positioning it between the positive and negative thread screws 110. Then, the stud 17 drives the moving frame 18 to move, adjusting the position of the clamping plate 111. The second motor 19 drives the positive and negative thread screws 110 to rotate, which in turn moves the clamping plates 111 on both sides towards the center. The clamping plates 111 clamp the edges of the screen. Then, the dispensing device 13 applies adhesive to the surface of the screen. Before placing the frame on the screen, the clamping plates 111 are separated from the sides of the screen. The frame and screen are then aligned. The frame and screen are then irradiated with ultraviolet light 14 to cure the adhesive on the screen. This step involves the stud 17 driving the moving frame 18 to move, adjusting the position of the clamping plates 111 to reinforce the screen. The positive and negative thread screws 110 move the clamping plates 111 towards the center, allowing the clamping plates 111 to clamp and limit screens of different sizes, increasing the applicability of positioning the screen on top of the base 1, and making the screen more stable during adhesive application.

[0019] like Figure 4 and Figure 5 As shown, an electric push rod 21 is fixedly connected to the side of the clamping plate 111, and a pressure plate 22 is fixedly connected to the moving end of the electric push rod 21. The pressure plate 22 is slidably connected to the clamping plate 111. During operation, the clamping plate 111 moves, driving the electric push rod 21 to move. The height of the pressure plate 22 can be adjusted by the electric push rod 21. When the frame and the screen are attached, the electric push rod 21 drives the pressure plate 22 to press down on the screen and the frame at the top of the base 1. This step allows the electric push rod 21 to drive the pressure plate 22 to press down on the attached frame and screen, pressing the screen and the frame tightly and improving their tightness.

[0020] like Figures 1 to 3As shown, the base 1 has a first groove 31 on both the front and rear sides, and a second groove 32 on the top of the clamping plate 111. During operation, the moving frame 18 can move the clamping plate 111 inside the first groove 31, and the pressure plate 22 can move inside the second groove 32. This step increases the distance the clamping plate 111 moves towards the center through the first groove 31, and increases the distance the pressure plate 22 moves downward through the second groove 32, thereby improving the applicability of the clamping plate 111 and the pressure plate 22 in limiting the screen and frame.

[0021] like Figure 2 As shown, a second sliding groove 41 is provided at the bottom of the base 1, and the second sliding groove 41 is slidably connected to the movable frame 18; this step can limit the two sides of the movable frame 18 through the second sliding groove 41, increasing the stability of the movable frame 18 when moving.

[0022] like Figure 4 As shown, a reinforcing block 51 is fixedly connected to the top of the positive and negative threaded screw 110, and one end of the clamping plate 111 is rotatably connected to the reinforcing block 51. In this step, the reinforcing block 51 can reinforce one end of the movable frame 18 and limit the distance that the electric push rod 21 moves outward. When the electric push rod 21 moves outward and its surface contacts the reinforcing block 51, the clamping plate 111 stops moving outward.

[0023] like Figure 3 As shown, several rollers 61 are rotatably connected to the inner side of the first groove 31. In this step, when the inner side of the clamping plate 111 contacts the surface of the rollers 61, the moving frame 18 drives the clamping plate 111 to move horizontally inside the first groove 31. At this time, the inner side of the clamping plate 111 drives the rollers 61 to rotate, which can prevent the clamping plate 111 from moving when it is in contact with the inner side of the first groove 31 and causing wear.

[0024] The working principle is as follows: the first motor 16 drives the stud 17 to rotate, which in turn drives the movable frame 18 to move inside the first slide groove 15. The movable frame 18 then drives the second motor 19 to move, adjusting the position of the two clamping plates 111 so that the operator can easily place the screen on top of the base 1, positioning it between the positive and negative thread screws 110. Then, the stud 17 drives the movable frame 18 to move again, adjusting the position of the clamping plates 111. The second motor 19 then drives the positive and negative thread screws 110 to rotate, which in turn drives the two clamping plates 111 to move towards the center, thus clamping the edges of the screen. Then, glue is applied to the surface of the screen using the glue dispensing device 13. Before placing the frame on the screen, the clamp 111 is first separated from the side of the screen. Then, the frame and the screen are aligned. The frame and the screen are then irradiated by turning on the ultraviolet lamp 14 to cure the glue on the screen. When the clamp 111 moves, it drives the electric push rod 21 to move. The height of the pressure plate 22 can be adjusted by the electric push rod 21. After the frame and the screen are attached, the electric push rod 21 drives the pressure plate 22 to press down on the screen and the frame at the top of the base 1. The moving frame 18 can drive the clamp 111 to move inside the first groove 31, and the pressure plate 22 can move inside the second groove 32.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
