Description

Technical Field

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

[0002] Optical filters are widely used in mobile phones, automotive, and display technologies. During the production process of optical filters, before cleaning or shipping, a protective film is often applied to the surface of the filter to ensure that its surface cleanliness is not affected during circulation and to prevent the filter surface from being scratched or chipped due to direct contact with hard objects.

[0003] The existing lamination method involves placing a steel ring with the filter on a platform and manually applying the protective film to the filter surface. This method relies heavily on the operator's experience and attention to detail, making it difficult to ensure that every filter is evenly covered with the protective film. Uneven pressure during manual lamination can cause filters to break, resulting in uneven lamination. Furthermore, an uneven platform surface can lead to air bubbles in the lamination process, hindering subsequent steps. Purely manual lamination without fixture assistance is no longer sufficient to meet current production requirements. Therefore, we propose a fixture to assist manual lamination and address these issues. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] The purpose of this invention is to provide a coating fixture to solve the problems existing in the prior art. With the assistance of the fixture, the coating is more flat and uniform, reducing scratches and edge breakage caused by uneven force during manual operation, and improving the production yield.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-4As shown, this embodiment provides a coating fixture, including a base plate 1, a suction plate 2, a crossbeam 3, a roller bracket 4, and a roller 5. The upper surface of the base plate 1 is provided with a vacuum groove 6, and a connector 7 is provided on one side of the base plate 1 to connect to the vacuum groove 6. The connector 7 is used to connect a vacuum pumping device. The suction plate 2 is attached to and fixed to the upper surface of the base plate 1 and completely covers the vacuum groove 6. There should be no gaps around the vacuum groove 6 to avoid air leakage. The vacuum groove 6 can be sealed with sealant. A suction cup 8 is fixedly provided on the upper surface of the suction plate 2. The suction cup 8 has multiple suction holes 9, and each suction hole 9 is connected to the vacuum groove 6. The crossbeam 3 is slidably disposed on the suction plate 2 and its sliding direction is parallel to the upper surface of the suction cup 8. The roller bracket 4 is connected to the crossbeam 3 through a height adjustment mechanism. The roller 5 is rotatably connected to the roller bracket 4 and located above the suction cup 8. The axis of the roller 5 is parallel to the upper surface of the suction cup 8.

[0023] In use, the steel ring 12 with the filter attached is placed on the suction plate 2. The UV film under the filter is flattened by the suction cup 8. Since the filter is attached to the UV film, it is also flattened. The operator places the protective film on top of the steel ring 12 to completely cover the filter. The height of the roller 5 is adjusted to a suitable position using the height adjustment mechanism. The crossbeam 3 is pushed to move the roller 5 horizontally, and the roller 5 evenly applies the protective film to the surface of the filter. After the protective film is flat, the vacuum is turned off, and the operator removes the steel ring 12 with the protective film applied. This laminating fixture allows the roller 5 to adhere the protective film and the filter at a set interval, thereby controlling the laminating pressure and making the laminating force more uniform. This ensures the flatness and uniformity of the protective film adhered to the filter, effectively reducing scratches and chipping caused by excessive force during manual operation, and insufficient laminating adhesion caused by insufficient force, thus improving production yield.

[0024] In this embodiment, the upper surface of the suction plate 2 is provided with material picking grooves 10 at both ends, which makes it easier for the operator to pick up the steel ring 12 and improves the work efficiency to a certain extent. The upper surface of the suction plate 2 is fixedly provided with positioning posts 11 for positioning the steel ring 12. The positioning posts 11 are located on the outside of the suction cup 8. The steel ring 12 is positioned by the positioning posts 11 to prevent the steel ring 12 from moving during the film coating process.

[0025] In this embodiment, the crossbeam 3 is an inverted U-shaped crossbeam. A slider 13 is fixedly connected to the bottom of each end of the inverted U-shaped crossbeam. A side plate 14 is fixedly connected to each side of the suction plate 2. A guide rail 15 is fixedly connected to each side plate 14. The two sliders 13 are slidably connected to the two guide rails 15. The cooperation between the guide rails 15 and the sliders 13 makes the movement of the crossbeam 3 more stable. Lubricating oil is applied between the sliders 13 and the guide rails 15 to ensure that the sliders 13 can perform reciprocating translational motion on the guide rails 15.

[0026] In this embodiment, limit blocks 16 are fixed at both ends of the guide rail 15 to limit the working stroke of the slider 13 and prevent the slider 13 from falling off the guide rail 15.

[0027] In this embodiment, the roller support 4 is an inverted U-shaped support, and the two ends of the central shaft of the roller 5 are respectively rotatably connected to the two ends of the inverted U-shaped support.

[0028] In this embodiment, a handle 17 is fixedly provided at the upper end of the crossbeam 3, which facilitates the reciprocating movement of the crossbeam 3.

[0029] In this embodiment, both ends of the roller support 4 are connected to the crossbeam 3 via a height adjustment mechanism. The height adjustment mechanism includes a fixing screw 18, a fixing nut 19, and a wing nut 20. The fixing screw 18 is fixed to the upper end of the roller support 4, and the upper end of the fixing screw 18 passes through a through hole on the crossbeam 3 and is threadedly connected to the wing nut 20. The fixing nut 19 is threadedly connected to the fixing screw 18 and is located on the lower side of the crossbeam 3. By cooperating with the fixing nut 19 and the wing nut 20, the height of the roller support 4 can be adjusted, thereby adjusting the height of the roller 5. This can meet the coating requirements of filters of different thicknesses, demonstrating the versatility of the fixture.

[0030] In this embodiment, a stepped groove 21 is provided at one end of the bottom of the vacuum groove 6, and the connector 7 communicates with the stepped groove 21. The vacuum groove 6 is relatively shallow. By setting a deeper stepped groove 21, the connector 7 can communicate with the vacuum groove 6 through the stepped groove 21 after the connector 7 is installed.

[0031] In this embodiment, the suction cup 8 is a square suction cup with chamfered corners 22 at its four corners. This facilitates the placement of the steel ring 12 on the surface of the suction plate 2, preventing the sharp corners of the suction cup 8 from cutting workers and scratching the UV film. The thickness of the steel ring 12 is the same as the thickness of the suction cup 8. The steel ring 12 is fitted onto the outside of the suction cup 8, allowing the UV film to fit snugly against the surface of the suction cup 8, thus improving UV film adhesion and preventing stress concentration.

[0032] In this embodiment, the roller 5 is an anti-static roller. The roller 5 is made of anti-static material to prevent static electricity from being generated when the roller 5 rolls, which would affect the coating effect. The roller 5 rolls to stick the protective film tightly to the surface of the filter.

[0033] The coating fixture provided in this embodiment has a simple structure, is easy to operate, ensures uniform stress on the filter during coating, has good coating flatness, long service life, high coating efficiency, and is lightweight, durable, easy to manufacture and maintain, thus reducing production costs.
