Description

Technical Field

[0001] This utility model belongs to the technical field of glass coating fixtures, and specifically relates to an optical glass coating fixture. Background Technology

[0002] Optical glass coating fixtures are tools used to fix and hold optical glass during the coating process. Their function is to ensure the optical glass is in the correct position and angle during coating, guaranteeing the uniformity and accuracy of the coating, and preventing displacement or shaking of the optical glass during the coating operation that could affect coating quality. This ensures the smooth completion of the coating process and the acquisition of high-quality coated optical glass products. For example, when coating optical glass components such as camera lenses, specially designed optical glass coating fixtures are used to fix the lens in place for coating.

[0003] Traditional optical glass clamps mostly use bolts for direct compression or mechanical snap-fit, which have extremely high requirements for glass thickness accuracy and are difficult to adapt to products of different specifications; moreover, the uneven distribution of clamping force can easily cause the glass to shift during the coating process, affecting the coating effect. Utility Model Content

[0016] Compared with the prior art, this utility model provides an optical glass coating fixture with the following features:

[0017] Beneficial effects:

[0018] 1. Traditional optical glass clamps mostly use bolts for direct pressing or mechanical snap-fit, which have extremely high requirements for glass thickness accuracy and are difficult to adapt to products of different specifications; moreover, the uneven distribution of clamping force can easily cause the glass to shift during the coating process, affecting the coating effect.

[0019] This clamp precisely adjusts the height of the upper magnet via a threaded rod, combining the dynamic balance of magnetic attraction and spring force to adaptively clamp optical glass of varying thicknesses. Whether it's ultra-thin lenses or thick glass sheets, it achieves uniform and stable clamping, avoiding compatibility issues caused by size differences.

[0020] 2. Existing rigid clamping methods can cause localized stress concentration on the glass surface, especially on irregularly shaped glass or lenses with thin edges, which can easily cause breakage; while simple magnetic clamps may cause the glass surface to be scratched or damaged by collisions when attracted due to excessive magnetic force.

[0021] In addition, the spring's buffering effect can effectively reduce the impact of magnetic attraction on the glass and evenly distribute the clamping force to the entire contact area; the flexible protection of the rubber ring further avoids direct contact between the glass and the magnet, reducing the risk of damage to the glass surface and significantly improving the product yield.

[0028] 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.

[0029] This utility model provides, for example Figure 1-5 An optical glass coating fixture is shown, including a back plate 1 and two fixing rods 2 disposed at the upper and lower ends of the front side of the back plate 1.

[0030] A fixing plate 3 is provided on the front side of the fixing rod 2, and clamping arms 4 are provided on the left and right ends of the front side of the fixing plate 3 respectively.

[0031] An upper clamping block 6 is provided at the end of the upper clamping arm 4, and a lower clamping block 7 is provided at the end of the lower clamping arm 4. A threaded rod 5 is provided on the inner side of the middle of the upper clamping block 6, and an upper magnet 11 is provided at the lower end of the threaded rod 5. A sleeve 8 is provided on the inner side of the middle of the lower clamping block 7, and a sleeve rod 13 is provided on the inner side of the middle of the sleeve 8. A lower magnet 10 is provided at the upper end of the sleeve rod 13, and a spring 9 is provided at the connection between the lower magnet 10 and the sleeve 8.

[0032] Rubber rings 12 are respectively provided on the outer side of the upper magnet 11 and the lower magnet 10.

[0033] Among them, the sleeve 8 and the lower clamping block 7 are fixedly connected, the threaded rod 5 is connected to the upper clamping block 6 by a threaded connection, the threaded rod 5 can move up and down on the upper clamping block 6 by the thread, the upper magnet 11 is fixedly connected to the threaded rod 5, the lower magnet 10 is fixedly connected to the sleeve rod 13, the sleeve rod 13 is connected to the sleeve 8 by a nesting connection, and the sleeve rod 13 can move up and down inside the sleeve 8, the upper and lower ends of the spring 9 are respectively connected to the lower magnet 10 and the upper end of the sleeve 8 by spot welding, the upper magnet 11 and the sleeve rod 13 move towards the bottom end of the sleeve 8 under the action of the spring force of the spring 9, the rubber ring 12 is connected to the upper magnet 11 and the lower magnet 10 by an inlay connection, and a rotating motor 15 is provided in the middle of the rear side of the back plate 1, and the connection between the rotating motor 15 and the back plate 1 is connected to the drive shaft 14, and the back plate 1 can rotate under the drive of the rotating motor 15.

[0034] In this embodiment, when installing the optical glass coating fixture, the user first fixes the back plate 1 at the designated position on the coating equipment. The rotary motor 15 on the rear side of the back plate 1 is connected to the equipment's power system via a drive shaft 14, ensuring that the rotary motor 15 can stably drive the back plate 1 to rotate. Next, two fixing rods 2 are respectively installed at the upper and lower ends of the front side of the back plate 1, and fixed by welding or high-strength bolts to ensure a stable connection between the fixing rods 2 and the back plate 1.

[0035] Next, the fixing plate 3 is installed on the front side of the fixing rod 2, which can be quickly fixed by bolts or clips. Then, the clamping arms 4 are installed on the left and right ends of the front side of the fixing plate 3, respectively. The clamping arms 4 are connected to the fixing plate 3 by hinges or slide rails to ensure that the clamping arms 4 can be flexibly adjusted in angle. Finally, the upper clamping block 6 and the lower clamping block 7 are installed on the ends of the upper and lower clamping arms 4, respectively, to complete the construction of the main structure of the fixture.

[0036] In use, the user first adjusts the vertical position of the upper magnet 11 in the upper clamping block 6 by turning the threaded rod 5, increasing the distance between the upper magnet 11 and the lower magnet 10 to reserve space for placing the optical glass. The optical glass to be coated is then placed horizontally on the rubber ring 12 on top of the lower magnet 10. The rubber ring 12 provides cushioning protection to prevent the glass surface from being scratched.

[0037] Next, the threaded rod 5 is turned down again to move it downwards. When the upper magnet 11 approaches the lower magnet 10, the lower magnet 10 is pulled upwards by the magnetic attraction between opposite magnetic poles. Since the sleeve rod 13 is fixedly connected to the lower magnet 10 and is fitted inside the sleeve 8, the lower magnet 10, under the force, drives the sleeve rod 13 to move upwards inside the sleeve 8 against the elastic force of the spring 9, until the upper and lower magnets tightly clamp the optical glass between the rubber ring 12 in the middle.

[0038] After clamping is complete, the rotating motor 15 is started, which drives the back plate 1 and the clamps on it to rotate as a whole through the transmission shaft 14. During the optical glass coating process, the rotation function can ensure that the glass surface is evenly coated with the coating material, avoiding local coatings that are too thick or too thin, thus improving the coating quality and efficiency.

[0039] Preferably, the core of this novel design lies in achieving efficient clamping through the synergistic effect of magnetism and spring. In use, the user manually adjusts the height of the upper magnet 11 by turning the threaded rod 5. The threaded connection between the threaded rod 5 and the upper clamping block 6 ensures precise height adjustment, adaptable to optical glass of varying thicknesses. After placing the glass, turning the threaded rod 5 again lowers the upper magnet 11. When the two magnets approach each other, a magnetic force is instantly generated, pulling the lower magnet 10 upwards.

[0040] Spring 9 plays a crucial role in this process: when the magnetic force pulls the magnet 10 upward, the spring 9 is compressed, generating a reverse elastic force that forms a dynamic balance with the magnetic force, ensuring that the clamping force acts evenly and stably on the optical glass. This design avoids the risk of stress concentration and breakage on the glass surface that may be caused by traditional rigid clamping (such as direct bolt pressure). At the same time, compared with simple magnetic attraction, the buffering effect of the spring can prevent damage to the glass caused by excessive magnetic force.

[0041] The rubber ring 12 further enhances the clamping effect. Its soft material conforms to the glass surface, not only providing anti-slip function, but also filling the tiny gap between the magnet and the glass, ensuring that the glass remains stable during the coating rotation and will not shift due to vibration or centrifugal force.

[0042] Optionally, the connection design between the rotating motor 15 and the back plate 1 ensures uniformity in the optical glass coating. After the motor is started, the drive shaft 14 transmits power to the back plate 1, causing the entire fixture to rotate at a uniform speed. During the coating process, the glass rotates with the fixture, allowing the coating material to cover all areas of the glass surface at the same time and angle.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
