[0001] This utility model relates to the field of diffusion plate production and processing technology, and in particular to a coating fixture for diffusion plate production. Background Technology

[0002] Coating fixtures for diffuser plate production are key auxiliary equipment in the process, playing a crucial role in ensuring the precise and efficient implementation of the coating process. Diffuser plates are widely used in numerous fields such as lighting, displays, and optical instruments, and different application scenarios place diverse requirements on their specifications and performance. In the coating stage, specific fixtures are needed to ensure that the film adheres evenly and flawlessly to the diffuser plate surface, thereby improving the optical performance, durability, and other quality indicators of the diffuser plate.

[0003] In actual diffusion plate production operations, the coating fixture typically has the following key components:

[0004] 1. The main body of the fixture is generally made of high-strength and corrosion-resistant metal. Its stable structure provides basic support for the entire coating operation, ensuring the overall stability of the fixture during complex operations.

[0005] 2. Positioning device: High-precision positioning pins, positioning blocks and other components are used to accurately determine the position of the diffuser plate on the fixture, ensuring the accuracy of the coating position and avoiding problems such as offset.

[0006] 3. Clamping mechanism: Common types include mechanical clamping, pneumatic clamping, and hydraulic clamping. These mechanisms can provide appropriate clamping force according to actual needs, firmly fixing the diffuser plate and preventing it from moving during lamination.

[0007] 4. Auxiliary structures, such as film guiding components, can guide the film to accurately cover the surface of the diffuser plate and avoid deviation during film laying; there are also venting components, which can effectively remove the air generated during the film coating process and prevent air bubbles from remaining between the film and the diffuser plate, affecting product quality.

[0008] Currently, various types of lamination fixtures exist on the market to meet the lamination requirements of diffusion plate production. Some manufacturers use fixed-structure lamination fixtures, which are designed for specific diffusion plate specifications and offer stability and cost advantages in single-specification product production. These fixtures are simple in structure and easy to operate and maintain. Other manufacturers use semi-automatic lamination fixtures, which improve the efficiency of some operations by introducing automated control components, such as motor-driven clamping devices. Some high-end lamination fixtures are equipped with advanced vision inspection systems that can monitor the quality status during the lamination process in real time.

[0009] However, the existing coating fixture implementation methods still have the following significant problems: in terms of adapting to different specifications of diffusion plates, most fixtures lack flexibility and are difficult to adjust quickly and conveniently to meet the production needs of various specifications of diffusion plates. When it is necessary to produce diffusion plates of different sizes and thicknesses, it is often necessary to replace the entire set of fixtures or make complex manual adjustments. This not only consumes a lot of time and labor costs, but also seriously affects production efficiency. In view of these problems, this application is committed to designing a new type of coating fixture for diffusion plate production. Through adjustable structural design and functional optimization, it can flexibly adapt to different specifications of diffusion plates, effectively ensure the stability of diffusion plate processing, and effectively improve the overall efficiency and product quality of diffusion plate production.

Through adjustable structural design and functional optimization, it can flexibly adapt to diffusion plates of different specifications, effectively ensuring stability during the diffusion plate processing and effectively improving the overall efficiency and product quality of diffusion plate production.

[0025] Example

[0026] As shown in Figures 1, 2, 3, and 4, the technical solution in this application effectively solves the problem that most fixtures lack flexibility in adapting to different specifications of diffusion plates, making it difficult to quickly and conveniently adjust them to meet the production needs of various specifications of diffusion plates. When it is necessary to produce diffusion plates of different sizes and thicknesses, it is often necessary to replace the entire set of fixtures or perform complex manual adjustments. This not only consumes a lot of time and labor costs but also seriously affects production efficiency. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a coating fixture for diffusion plate production, including a worktable 1. Two clamping plates 3 are provided on the upper surface of the worktable 1 for clamping. Two support frames 2 are provided below the worktable 1. Connecting frames 7 are movably engaged on the upper surfaces of both support frames 2. A screw 6 is threaded onto the upper surface of the worktable 1. A U-shaped block 15 is movably connected inside the worktable 1. A support platform 5 for supporting the diffusion plate is fixedly connected to the upper surface of the U-shaped block 15. A fixing frame 14 is fixedly connected between the two support frames 2. A connecting cylinder 12 is fixedly connected inside the fixing frame 14. Two limiting posts 9 are movably sleeved inside the connecting cylinder 12. Return springs 10 are fixedly connected to the opposite faces of the two limiting posts 9. Both connecting frames 7 are fixedly connected to the worktable 1. A cylinder 4 is fixedly installed on the front surface of the worktable 1. The piston of the cylinder 4 is fixedly connected to the front clamping plate 3 of the two clamping plates 3. The front clamping plate 3 of the clamping plates 3 is movably connected to the worktable 1. During use, the diffuser plate is placed on the support platform 5. By activating the cylinder 4, the piston will drive the fixed clamping plate 3 to move. The movement of the clamping plate 3 will clamp and fix the diffuser plate. Rubber plates are provided on the opposite surfaces of the two clamping plates 3 to increase friction. Before clamping, rotating the screw 6 upward will drive the rotatably connected U-shaped block 15 to move together. During the movement of the U-shaped block 15, the fixed support platform 5 will move together. The movement of the support platform 5 will drive the diffuser plate placed on it to move together. At this time, the placement height of the diffuser plate can be adjusted according to the needs. The thickness of diffuser plates of different models and sizes may be different. By adjusting the height of the support platform 5, the diffuser plate can always be in a suitable operating height and clamping position, which is convenient for operators to perform operations such as coating, and ensures the accuracy and efficiency of the work.

[0028] Both support frames 2 have slots 8 on their upper surfaces, which are movably connected to the two connecting frames 7. The screw 6 is rotatably connected to the U-shaped block 15. A fixing post 11 is fixedly connected inside the connecting cylinder 12. The fixing post 11 is fixedly connected to two return springs 10. Both connecting frames 7 have a set of circular grooves 13 on their opposite surfaces. The two sets of circular grooves 13 are movably engaged with two limiting posts 9. Pressing the two limiting posts 9 relative to each other causes them to disengage from the two sets of circular grooves 13 on the two support frames 2, compressing the two return springs 10 and opening the limits. At this time, the worktable 1 fixed to the two connecting frames 7 can be moved up and down for adjustment. After adjustment, the two return springs 10 are used to reset the worktable 2 and the connecting frame 7, making them fixed. In addition to the coating operation of the diffuser plate, other related production processes such as cutting and assembly may be performed on the worktable 1. Different processes require different heights of the worktable 1 to achieve the best operating effect. The adjustable worktable 1 can meet these diverse production needs and improve the overall practicality.

[0029] Among them, the workbench 1 is the basic platform of the entire coating fixture. The upper surface is equipped with components such as the clamping plate 3 and the screw 6, and the lower part is connected to the support frame 2. Its height is adjustable, providing an operating plane for coating the diffusion plate and other production processes.

[0030] Support frame 2: Located below the workbench 1, it supports the workbench 1. The slot 8 on its surface cooperates with the connecting frame 7 to enable the height adjustment of the workbench 1 and ensure the overall stability of the fixture.

[0031] Clamping plate 3: Installed on the upper surface of the workbench 1, the two clamping plates 3 can clamp and fix the diffuser plate under the drive of the cylinder 4. The rubber plates on the opposite sides can increase the friction to ensure that the diffuser plate does not move during the coating process.

[0032] Cylinder 4: Fixed on the front surface of the worktable 1, its piston is connected to the clamping plate 3 in front. After starting, it pushes the clamping plate 3 to move, realizing the clamping action of the diffuser plate and providing fixed power for the coating operation.

[0033] Support platform 5: Fixed on the upper surface of U-shaped block 15, used to place the diffusion plate. It can move with U-shaped block 15. By adjusting its height, the diffusion plate can be placed in a suitable operating position, which is convenient for operations such as coating.

[0034] Screw 6: It is threaded onto the upper surface of the worktable 1 and rotatably connected to the U-shaped block 15. Rotating the screw 6 can drive the U-shaped block 15 and the support table 5 to move, thereby adjusting the placement height of the diffuser plate to meet the needs of diffuser plates of different specifications.

[0035] Connecting frame 7: It is attached to the upper surface of the support frame 2 and fixedly connected to the worktable 1. Together with the limiting post 9, return spring 10 and other components, it realizes the up and down adjustment of the worktable 1 to adapt to the height requirements of the worktable 1 in various production processes.

[0036] Slot 8: It is formed on the upper surface of the support frame 2 and is movably connected to the connecting frame 7. During the height adjustment of the worktable 1, it plays a positioning and guiding role, ensuring the stable movement of the connecting frame 7 and ensuring the accuracy of the adjustment of the worktable 1.

[0037] Limiting post 9: It is movably sleeved inside the connecting cylinder 12 and cooperates with the circular groove 13 on the connecting frame 7. When the height of the worktable 1 is adjusted, the limiting post 9 is released from the circular groove 13 to unlock it. After the adjustment is completed, it is reset and fixed to limit the position of the worktable 1.

[0038] Return spring 10: Connected between the opposite surfaces of the two limit posts 9 and the fixed post 11, after the height of the worktable 1 is adjusted, the spring force is used to reset the limit posts 9 and re-engage them into the circular groove 13 of the connecting frame 7 to fix the height of the worktable 1.

[0039] Fixed column 11: Fixed inside the connecting cylinder 12, used to fix the return spring 10, provide a support point for the return spring 10, and ensure that the return spring 10 can stably exert its elastic force during operation to achieve positioning after the height of the worktable 1 is adjusted;

[0040] Connecting cylinder 12: Fixed inside the fixed frame 14, with the limiting post 9 movably sleeved inside, providing space for the limiting post 9 to move within the connecting cylinder 12, and working with other components to complete the locking and unlocking functions of the worktable 1 height adjustment;

[0041] Circular groove 13: It is opened on the opposite side of the connecting frame 7 and is movably connected with the limiting post 9. When the height of the worktable 1 is adjusted, the limiting post 9 is engaged or disengaged from the circular groove 13 to limit and adjust the height of the worktable 1 and ensure the accuracy of the adjustment.

[0042] Fixed frame 14: connects two support frames 2, fixes the connecting cylinder 12, enhances the stability between the support frames 2, provides an installation base for components such as the connecting cylinder 12 and the limiting column 9, and ensures the reliability of the entire height adjustment structure;

[0043] U-shaped block 15: It is movably connected inside the worktable 1, with a fixed support platform 5 on its upper surface. It is rotatably connected to the screw 6. When the screw 6 rotates, it drives the U-shaped block 15 and the support platform 5 to move, thereby adjusting the placement height of the diffuser plate.

[0044] Working principle:

[0045] During use, the diffuser plate is placed on the support platform 5. Activating the cylinder 4 causes the piston to move the fixed clamping plate 3, which clamps and secures the diffuser plate. Rubber plates are provided on the opposing surfaces of both clamping plates 3 to increase friction. Before clamping, rotating the screw 6 upwards moves the rotatably connected U-shaped block 15. The movement of the U-shaped block 15 moves the fixed support platform 5, which in turn moves the diffuser plate placed on it. The height of the diffuser plate can then be adjusted as needed. Different models and sizes of diffuser plates may have different thicknesses; adjusting the height of the support platform 5 ensures the diffuser plate is always at a suitable operating height and clamping position, facilitating operation. To ensure accuracy and efficiency, operators perform operations such as film coating. By pressing the two limit posts 9, they disengage from the two sets of circular grooves 13 on the two support frames 2, compressing the two return springs 10 and opening the limit. At this time, the worktable 1, which is fixed to the two connecting frames 7, can be moved up and down for adjustment. After adjustment, the two return springs 10 are used to reset the support frame 2 and the connecting frame 7, making them fixed. In addition to the film coating operation of the diffuser plate, other related production processes such as cutting and assembly may be performed on the worktable 1. Different processes require different heights of the worktable 1 to achieve the best operating effect. The adjustable worktable 1 can meet these diverse production needs and improve the overall practicality.

[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
