Description

Technical Field

[0001] This utility model relates to the field of coating fixture technology, specifically to a slide rail adjustable multi-station coating fixture. Background Technology

[0002] With the continuous development of optical lens technology, optical lens coating technology has become increasingly mature. The conventional method of coating is to hold the glass slide with a coating fixture. The coating fixture is a key tooling equipment used in processes such as vacuum coating and optical coating. It is mainly used to fix and position the workpiece to ensure the uniformity and accuracy of the coating.

[0003] Currently, existing optical lens coating fixtures are inconvenient for picking up and placing glass slides. Due to the limited number of workstations for holding glass slides, the coating efficiency is low. Furthermore, the thermal expansion coefficients of metal fixtures (such as aluminum alloys) and optical glass differ greatly, which can easily lead to localized stress concentration in the lens during high-temperature coating, causing the lens to crack or undergo micro-deformation.

[0004] Based on this, the present invention designs a slide rail adjustable multi-station coating fixture to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example Please see Figure 1-7The present invention provides the following technical solution: a slide rail adjustable multi-station coating fixture, including a base 1, a connecting plate 2, a slide rail 3, a ball screw 4, a drive motor 5, a sliding seat 6, a ball nut 7, and a fixture assembly 8. The two ends of the two bases 1 are fixedly connected by the connecting plate 2. The ball screw 4 is movably installed between the two connecting plates 2. One end of the ball screw 4 is connected to the drive motor 5. The drive motor 5 is fixedly installed on the right connecting plate 2 by screws. The upper ends of the two bases 1 are fixedly connected to the slide rail 3. The sliding seat 6 is slidably installed on the slide rail 3. The fixture assembly 8 is fixedly installed on the upper end of the sliding seat 6. The clamp assembly 8 includes a clamp body 801, a mounting block 802, limiting posts 803, positive and negative threaded rods 804, a moving plate 805, a sliding block 806, a guide block 807, a clamping plate 808, a placement plate 809, and a second rubber pad 8010. The mounting block 802 is fixedly connected to the lower end of the center of the clamp body 801. Three limiting posts 803 are provided on the lower part of both ends of the clamp body 801. Three sets of sliding grooves are symmetrically opened on the upper end of the clamp body 801, and each set of sliding grooves is equipped with... A movable plate 805 is provided, and two guide blocks 807 are symmetrically provided at the lower end of each movable plate 805. A sliding block 806 is provided between the two guide blocks 807. The movable plate 805 is movably connected to the corresponding positive and negative threaded rods 804 through the sliding block 806 at the lower end. The positive and negative threaded rods 804 are movably installed in the corresponding sliding grooves, and a rotating head 8041 is provided at one end of the positive and negative threaded rods 804 that protrudes from the clamping body 801. A clamping plate 808 is provided on each of the two opposing movable plates 805 in the same group.

[0017] The clamping plate 808 includes a plate body 8081, a first rubber gasket 8082, an inner rod 8083, a spring 8084, and an outer cylinder 8085. The first rubber gasket 8082 is fixedly connected to one end of the plate body 8081, and the inner rod 8083 is fixedly connected to the other end of the plate body 8081. The spring 8084 is fixedly connected to one end of the inner rod 8083. The spring 8084 is fixedly connected inside the outer cylinder 8085, and the outer cylinder 8085 is embedded in the interior of the movable plate 805.

[0018] Through the structural design of the movable plate 805, the first rubber pad 8082 provided on the plate 8081 allows the lens to flexibly contact the plate 8081, protecting the lens. After clamping and fixing, during the high-temperature coating process, when the lens undergoes thermal expansion, the expansion of the lens compresses the plate 8081, and the spring 8084 can be compressed, thereby avoiding the rigid clamping that could cause the lens to crack or deform.

[0019] A placement plate 809 is fixedly connected to the center of the upper end of the clamping body 801, and a second rubber gasket 8010 is fixedly connected to the upper end of the placement plate 809.

[0020] The second rubber pad 8010 provided on the placement plate 809 provides good anti-slip properties while preventing the optical lens from directly rubbing against the placement plate 809 and causing scratches.

[0021] The second rubber gasket 8010 and the first rubber gasket 8082 are made of suitable high-temperature resistant rubber materials according to the requirements of high-temperature coating.

[0022] A mounting groove 601 is provided at the center of the sliding seat 6. Six mounting holes are symmetrically provided in the mounting groove 601, and each mounting hole is provided with a connecting bolt 603. Three limiting holes 602 are provided above both ends of the sliding seat 6.

[0023] The limiting posts 803 at the lower ends of both sides of the clamp assembly 8 are respectively inserted into the limiting holes 602 opened at the upper ends of the sliding seat 6. The mounting block 802 at the center of the lower end of the clamp assembly 8 is fixedly connected in the mounting groove 601. The sliding seat 6 is fixedly connected to the clamp assembly 8 by multiple connecting bolts 603.

[0024] The aforementioned clamp assembly 8 and sliding seat 6 are connected and fixed by limiting posts and bolts, which facilitates the installation and disassembly of the clamp assembly 8 and provides good flexibility.

[0025] A ball nut 7 is fixedly installed at the center of the lower end of the sliding seat 6 by bolts, and the ball nut 7 at the lower end of the sliding seat 6 is movably connected to the ball screw 4.

[0026] The aforementioned sliding seat 6 is connected to the ball screw 4 via the ball nut 7, thereby driving the ball nut 7 to move through the ball screw 4, thus enabling the sliding seat 6 to move along the slide rail 3, and allowing the clamp assembly 8 to achieve slide rail adjustment.

[0027] The working principle and usage process of this utility model are as follows: In specific use, the workpiece to be coated is placed on the placement plate 809 at the center of the fixture assembly 8, and the workpiece is positioned between each set of fixtures. Then, the rotating head 8041 drives the positive and negative threaded rods 804 to rotate. The rotation of the positive and negative threaded rods 804 causes two moving plates 805, which are movably connected to the positive and negative threads respectively by the sliding block 806, to move towards each other along the slide groove. Through the opposite movement of the two moving plates 805, the workpiece is elastically clamped by the clamping plate 808. The same operation can be performed on other sets of fixtures. Multiple sets of workpieces can be clamped at one time, improving coating efficiency. When it is necessary to move and position the fixture, the drive motor 5 drives the rotation of the ball screw 4, which allows the sliding seat 6 to move and adjust along the slide rail 3, ensuring that the position of the workpiece is accurately controllable during the coating process and avoiding uneven coating caused by displacement.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
