Description

Technical Field

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

[0002] In modern industrial manufacturing, glass vacuum coating technology is widely used in optics, electronics, and construction to improve the performance of glass surfaces, such as enhancing wear resistance, anti-reflection, or conductivity. However, the design and use of the fixture plays a crucial role in the coating quality during the glass vacuum coating process. Existing glass vacuum coating fixtures often have some shortcomings, such as unstable clamping, easy damage to the glass surface, or uneven coating. Furthermore, traditional fixtures often require complex adjustments or component replacements when adapting to glass substrates of different sizes and shapes, increasing operational difficulty and production costs. At the same time, the sealing and durability of existing fixtures in a vacuum environment also have certain limitations, which may affect the stability and efficiency of the coating process. Therefore, there is an urgent need for a new type of glass vacuum coating fixture that can solve the above problems, improve clamping stability, adapt to various specifications of glass substrates, and ensure the high efficiency and reliability of the coating process. Utility Model Content

[0006] A further technical solution of this utility model is: a screw is provided inside the slider, and a handwheel connected to the screw is provided on the outside of the slider.

The clamping plate is used to fix the glass, the elastic pad is used to buffer the pressure on the glass surface, and the locking knob is used to adjust the tightness of the clamping plate to ensure stable clamping without damaging the glass surface.

[0009] A further technical solution of this utility model is: the inner side of the clamping plate is provided with a groove, the position of the groove corresponds to the elastic pad, so that the elastic pad can be embedded in the groove to increase the stability during clamping.

[0018] This utility model provides a glass vacuum coating fixture, which achieves efficient and stable clamping of glass through the coordinated operation of a base 1, a clamping mechanism 2, and an adjusting bracket 3, effectively avoiding damage to the glass surface during the clamping process. The following description, in conjunction with the appendix... Figures 1 to 3 The accompanying diagrams and reference numerals are described in detail. The overall structure is as follows: Figure 1 As shown, the core components of the clamp include a base 1, a clamping mechanism 2, and an adjusting bracket 3. The base 1 is the main structure. The clamping mechanism 2 is movably connected to the base 1 via a slider 4. The adjusting bracket 3 is located on one side of the base 1 and has a "C"-shaped design, used to adjust the clamping height and angle. The structure of the clamping mechanism 2 is further detailed as follows... Figure 2 As shown, it mainly includes a clamping plate 8, an elastic pad 9, and a locking knob 10. These components work together to achieve precise clamping of the glass. The mating relationship between the slider 4 and the base 1 is as follows. Figure 3 As shown, the coordinated operation of the screw 5, handwheel 6, guide rail 7 and internal threaded hole 14 ensures that the slider 4 can move precisely in the horizontal direction.

[0019] In practical implementation, the base 1 serves as the basic structure of the entire fixture, equipped with a guide rail 7 and an internal threaded hole 14, providing guidance and drive support for the horizontal movement of the slider 4. A screw 5 is installed inside the slider 4, with one end extending to the outside of the slider 4 and connecting to a handwheel 6. By rotating the handwheel 6, the screw 5 rotates accordingly. Since the screw 5 matches the internal threaded hole 14 on the base 1, the rotation of the screw 5 translates into the horizontal movement of the slider 4 along the guide rail 7. This design allows the clamping mechanism 2 to flexibly adjust its position according to actual needs, thereby adapting to glass workpieces of different sizes or shapes.

[0020] The specific structure of clamping mechanism 2 is as follows Figure 2As shown, its core component, the clamping plate 8, is used to directly contact and fix the glass workpiece. The inner side of the clamping plate 8 has a groove 11, the position of which corresponds to the elastic pad 9, allowing the elastic pad 9 to be embedded within it to increase stability during clamping. The elastic pad 9 is made of a highly elastic material, and its side away from the clamping plate 8 has anti-slip texture 13, the surface of which is coated with a silicone coating. This design not only enhances the friction between the elastic pad 9 and the glass surface but also effectively prevents the glass from slipping during clamping. Furthermore, the presence of the elastic pad 9 also acts as a buffer, preventing the clamping plate 8 from directly contacting the glass surface and causing damage. A locking knob 10 is located on the outer side of the clamping plate 8. Rotating the locking knob 10 adjusts the tightness of the clamping plate 8, thereby ensuring the stability and safety of the clamping.

[0021] The design of the adjustment bracket 3 is as follows Figure 1 As shown, it has a "C"-shaped structure with multiple positioning holes 12 on the side. The main function of the adjusting bracket 3 is to adjust the clamping height and angle according to the size and processing requirements of the glass workpiece. In actual operation, the user can select the appropriate positioning holes 12 as needed and fix the adjusting bracket 3 on the base 1, thereby achieving precise control of the clamping angle. For example, when processing larger glass workpieces, the clamping height can be increased by adjusting the bracket 3 to provide more operating space for subsequent coating processes; while when processing smaller glass workpieces, the clamping height can be decreased to enhance clamping stability.

[0022] The working principle of this utility model is as follows: First, the glass workpiece to be processed is placed between the clamping plates 8 of the clamping mechanism 2. The tightness of the clamping plates 8 is adjusted by rotating the locking knob 10, so that the elastic pad 9 is in close contact with the glass surface. During this process, the anti-slip texture 13 and silicone coating of the elastic pad 9 can effectively prevent the glass from sliding, while reducing the impact of clamping pressure on the glass surface. Next, according to the size of the glass workpiece and the processing requirements, the handwheel 6 is rotated to drive the screw 5 to rotate, so that the slider 4 moves horizontally along the guide rail 7, thereby adjusting the position of the clamping mechanism 2. Finally, the clamping height and angle are adjusted by adjusting the positioning hole 12 on the bracket 3 to ensure the stability and processing accuracy of the glass workpiece during the coating process.

[0023] In practical applications, the glass vacuum coating fixture of this invention can be widely used in various glass processing production lines. For example, in automotive glass coating processes, this fixture can quickly and accurately fix glass workpieces of different sizes and shapes, and adjust the clamping angle by adjusting the bracket 3 to adapt to complex coating paths. Furthermore, due to the excellent cushioning performance of the elastic pad 9 of the clamping mechanism 2, this fixture can also be used for processing precision optical glass, avoiding scratches or other damage to the glass surface during clamping.

[0024] In summary, this utility model provides a glass vacuum coating fixture that achieves efficient and stable clamping of glass workpieces through the coordinated operation of the base 1, clamping mechanism 2, and adjusting bracket 3. It features a simple structure, low cost, and can be used in large quantities. Furthermore, it offers convenient operation and high clamping precision, significantly improving the processing efficiency of glass vacuum coating.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
