Technical Field
[0001] This utility model relates to the field of hardware processing technology, specifically to a glass coating device with a positioning fixture. Background Technology
[0002] As living standards improve, people have higher and higher requirements for the appearance of electronic products. In order to make electronic products more durable and beautiful, vacuum coating is carried out during the product processing.
[0003] However, in actual use, the above-mentioned equipment requires limiting the glass for coating. The glass is clamped at both ends by telescopic cylinders. During the clamping process, the glass is easily over-clamped, which can damage the glass. In view of this, we propose a glass coating device with positioning fixture. Utility Model Content
[0004] The purpose of this invention is to provide a glass coating device with a positioning fixture to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass coating device with a positioning fixture, comprising a mounting platform, a bracket fixedly mounted on the upper surface of the mounting platform, a telescopic cylinder fixedly mounted on the upper surface of the bracket, a movable plate provided on the upper surface of the mounting platform, a positioning mechanism provided on the upper surface of the mounting platform, and a promoting mechanism provided on the upper surface of the mounting platform, wherein the positioning mechanism includes:
[0006] A threaded rod is threadedly connected to the inner wall of the movable plate, and a positioning block is rotatably connected to the end of the threaded rod;
[0007] A reset spring, one end of which is fixedly connected to the inner wall of the moving plate, and the other end of which is fixedly connected to a ball.
[0008] Preferably, the promoting mechanism includes a straight rod, which is fixedly mounted on the surface of the movable plate. A torsion spring is fixedly connected to the arc surface of the straight rod, and the end of the torsion spring away from the arc surface of the straight rod is fixedly connected to the inner wall of the limiting plate.
[0009] Preferably, the side wall of the limiting plate has a circular hole, and the limiting plate is sleeved on the arc surface of the straight rod, so that the limiting plate can rotate on the arc surface of the straight rod.
[0010] Preferably, the side wall of the movable plate is provided with a mounting groove, and a straight rod is fixedly installed on the inner wall of the mounting groove. The straight rod is fixedly installed inside the mounting groove.
[0011] Preferably, the side wall of the movable plate is provided with a cylindrical groove, the shape of which is adapted to the shape of the sphere, so that the sphere moves inside the cylindrical groove in conjunction with the return spring.
[0012] Preferably, the number of spheres is set to several, and the several spheres are arranged in a linear array on the upper surface of the moving plate. The arrangement of multiple spheres facilitates the movement of the glass.
[0013] Preferably, the side wall of the movable plate is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a threaded rod, so as to facilitate the adjustment of the threaded rod to drive the positioning block to limit the two sides of the glass.
[0014] Compared with the prior art, the present invention provides a glass coating device with a positioning fixture, which has the following advantages:
[0015] 1. The glass coating device with positioning fixture has a positioning mechanism that places the glass on the surface of a moving plate. The return spring and the ball facilitate the movement of the glass plate on the upper surface of the moving plate. Once the glass plate is moved to the appropriate position, it is positioned. The threaded rod is adjusted so that the positioning block on the threaded rod fixes the glass, thereby reducing damage caused by excessive clamping of the glass.
[0016] 2. The glass coating device with positioning fixture is equipped with a promoting mechanism. Under the continuous force of the torsion spring, the limiting plate is reliably pressed against the upper surface of the glass, which not only locks the glass position but also avoids damage from excessive pressure, providing a stable support for subsequent coating processes.

[0022] like Figures 1-4As shown, this utility model provides a technical solution: a glass coating device with a positioning fixture, including a mounting platform 1, a bracket 2 fixedly mounted on the upper surface of the mounting platform 1, a telescopic cylinder 5 fixedly mounted on the upper surface of the bracket 2, a movable plate 6 provided on the upper surface of the mounting platform 1, a positioning mechanism 3 provided on the upper surface of the mounting platform 1, and a promoting mechanism 4 provided on the upper surface of the mounting platform 1. The positioning mechanism 3 includes a threaded rod 301, a positioning block 302, a return spring 303, and a ball 304.
[0023] In one embodiment of this utility model, the threaded rod 301 is threadedly connected to the inner wall of the movable plate 6, and the end of the threaded rod 301 is rotatably connected to the positioning block 302. One end of the reset spring 303 is fixedly connected to the inner wall of the movable plate 6, and the other end of the reset spring 303 is fixedly connected to the ball 304.
[0024] In addition, the promoting mechanism 4 includes a straight rod 401, which is fixedly installed on the surface of the movable plate 6. A torsion spring 402 is fixedly connected to the arc surface of the straight rod 401. The end of the torsion spring 402 away from the arc surface of the straight rod 401 is fixedly connected to the inner wall of the limiting plate 403. A circular hole is opened on the side wall of the limiting plate 403. The limiting plate 403 is sleeved on the arc surface of the straight rod 401 and can rotate on the arc surface of the straight rod 401.
[0025] In this embodiment of the invention, the side wall of the movable plate 6 is provided with a mounting groove, and a straight rod 401 is fixedly installed on the inner wall of the mounting groove. The straight rod 401 is fixedly installed inside the mounting groove. The side wall of the movable plate 6 is provided with a cylindrical groove, the shape of which is adapted to the shape of the sphere 304, so that the sphere 304 moves inside the cylindrical groove in conjunction with the return spring 303. Several spheres 304 are provided, and several spheres 304 are arranged in a linear array on the upper surface of the movable plate 6. The arrangement of multiple spheres 304 facilitates the movement of the glass. The side wall of the movable plate 6 is provided with a threaded hole, and a threaded rod 301 is threadedly connected to the inner wall of the threaded hole, so as to facilitate the adjustment of the threaded rod 301 to drive the positioning block 302 to limit the two sides of the glass.

The movable end of the telescopic cylinder 5 is provided with a coating mechanism to facilitate coating the surface of the glass.
[0026] In this invention, when in use, the glass is placed on the surface of the movable plate 6. The reset spring 303, in conjunction with the ball 304, facilitates the movement of the glass plate on the upper surface of the movable plate 6. Once the glass plate is moved to a suitable position, it is positioned. The threaded rod 301 is adjusted, thereby fixing the glass plate with the positioning block 302 on the threaded rod 301, thus reducing damage caused by excessive clamping of the glass.
[0027] Furthermore, under the continuous force of the torsion spring 402, the limiting plate 403 is reliably pressed against the upper surface of the glass, which not only locks the glass position but also avoids damage from excessive pressure, providing stability for subsequent coating processes.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
