Description

Technical Field

[0001] This utility model belongs to the field of optical coating technology, and specifically relates to a positioning device for optical coating of panels. Background Technology

[0002] Optical coating refers to the process of depositing one (or more) thin films of metal (or dielectric) onto the surface of optical components. The purpose of coating the surface of optical components is to achieve requirements such as reducing or increasing light reflection, beam splitting, color separation, filtering, and polarization. Commonly used coating methods include vacuum coating (a type of physical coating) and chemical coating.

[0003] Existing positioning fixtures are devices that fix the optical components to be coated in a corresponding position. After the optical components to be coated are placed on the placement table, the coating plate coats the optical components. Currently, the fixtures used for optical coating processing on the market can only process optical components of a fixed size and cannot adjust the size of the fixture to fix the shape according to the size of the optical components. Therefore, they need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for optical coating of panels, in order to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A positioning device for optical coating of a panel includes a base plate, wherein a positioning mechanism is mounted on the upper end of the base plate. The positioning mechanism includes a driving component, which is driven by four gears. The four gears are fixedly mounted with threaded rods. The upper end of the base plate has four sliding grooves. Sliding plates that are threadedly connected to the threaded rods are slidably connected inside the four sliding grooves. An mounting plate extending out of the base plate is fixedly mounted on the upper end of the sliding plate. A clamping component is mounted on the mounting plate.

[0007] The clamping element includes a spring mounted to the mounting plate, and the spring is fixedly mounted with a positioning plate that abuts against the base plate.

[0008] A limiting plate that extends into the sliding groove is fixedly installed at the lower end of the positioning plate.

[0009] The spring is fixedly mounted on a connecting plate, and the connecting plate and the mounting plate are threadedly connected to a threaded post.

[0010] The threaded post is equipped with a handle.

[0011] The drive assembly includes a drive motor mounted on the lower end of the base plate, a drive gear mounted on the output end of the drive motor, an internal gear ring rotatably mounted inside the base plate that meshes with the drive gear, and meshing teeth that mesh with the gear fixedly mounted on the upper end of the internal gear ring.

[0012] An electric suction cup is installed in the center of the base plate.

[0013] This invention enables a number of sliding plates and clamping parts to move closer or further apart as the four threaded rods are rotated by a drive component, thereby positioning and abutting the panel. This makes the operation more convenient and faster. At the same time, the spring installed can play a buffering role. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1: As Figure 1-3 As shown, the present invention provides a positioning device for optical coating of a panel, comprising a base plate 1, wherein a positioning mechanism is mounted on the upper end of the base plate 1. The positioning mechanism comprises a drive assembly, which is connected to four gears 11. Threaded rods 12 are fixedly mounted on the four gears 11. Four sliding grooves 13 are provided on the upper end of the base plate 1. Sliding plates 14 that are threadedly connected to the threaded rods 12 are slidably connected inside the four sliding grooves 13. Mounting plates 15 that extend out of the base plate 1 are fixedly mounted on the upper end of the sliding plates 14. Clamping components are mounted on the mounting plates 15.

[0022] The clamping component includes a spring 20 mounted to the mounting plate 15, and the spring 20 is fixedly mounted with a positioning plate 21 that abuts against the base plate 1.

[0023] A limiting plate 22 that extends into the sliding groove 13 is fixedly installed at the lower end of the positioning plate 21.

[0024] An electric suction cup 30 is installed in the center of the base plate 1. The electric suction cup 30, which is based on existing technology, is used to adhere to the panel.

[0025] In use, place the panel on the top of the base plate 1 and then start the drive assembly to drive the four gears 11 to rotate together, which in turn drives the four threaded rods 12 to rotate. Since the sliding plate 14 is slidably connected to the sliding groove 13, the sliding plate 14 can only slide towards the center along the direction of the sliding groove 13 under the rotation of the threaded rod 12. As a result, the four sliding plates 14 and the clamping parts will move closer to each other, thereby positioning and clamping the panel. Finally, the panel located in the center can be suctioned by the electric suction cup 30 for subsequent operations.

[0026] When the mounting plate 15 moves, it drives the spring 20 and the positioning plate 21 to move, thereby positioning the positioning plate 21 against the panel. Simultaneously, the spring 20 prevents the positioning plate 21 from making rigid contact with the panel. Similarly, after two symmetrical positioning plates 21 have contacted the panel, if the other two positioning plates 21 are not, the spring 20 can keep the mounting plate 15 moving closer until the other two positioning plates 21 are in contact with the panel. The limiting plate 22 limits the movement of the positioning plate 21, allowing it to move along the sliding groove 13.

[0027] This invention enables a number of sliding plates and clamping parts to move closer or further apart as the four threaded rods are rotated by a drive component, thereby positioning and abutting the panel. This makes the operation more convenient and faster. At the same time, the spring installed can play a buffering role.

[0028] Example 2: Based on Example 1, a further improvement is made. The spring 20 is fixedly installed with a connecting plate 23, and the connecting plate 23 and the mounting plate 15 are threadedly connected with a threaded post 24.

[0029] The threaded post 24 is fitted with a handle 25.

[0030] The drive assembly includes a drive motor 26 mounted on the lower end of the base plate 1. A drive gear 27 is mounted on the output end of the drive motor 26. An internal gear ring 28 that meshes with the drive gear 27 is rotatably mounted inside the base plate 1. A meshing tooth 29 that meshes with the gear 11 is fixedly mounted on the upper end of the internal gear ring 28.

[0031] When dealing with panels with large differences in length and width, the clamping parts can be replaced to change the elastic coefficient of the spring 20. Under the action of the spring 20, all four positioning plates 21 can abut against the panel. When replacing, simply turn the handle 25 to drive the threaded post 24 to rotate and contact the connection between the connecting plate 23 and the mounting plate 13 to remove the connecting plate 23, spring 20 and positioning plate 21, and then install a more suitable spring 20.

[0032] The drive motor 26 drives the drive gear 27 to rotate, which in turn drives the internal gear ring 28 and several meshing teeth 29 to rotate. The meshing teeth 29 drive the gear 11 to rotate, which in turn drives the threaded rod 12 to rotate.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
