Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a loading fixture for a vacuum coating machine. Background Art

[0002] Vacuum coating is a coating technology that uses physical methods in a vacuum environment to vaporize the surface of the material source into gaseous atoms, molecules or partially ionize them into ions, and deposits them on the surface of the substrate through low-pressure gas. It is mainly divided into evaporation deposition coating and sputtering deposition coating.

[0003] Vacuum coating technology is gaining increasing attention and widespread use. When coating recessed housings, such as plastic phone cases, if they are hung directly on a hanger, the coating machine drives the hanger to rotate during the coating process, causing the product to fall and resulting in poor stability. Using a contoured mold requires mold opening, which is costly, time-consuming, and inconvenient to disassemble and assemble, impacting coating efficiency. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a loading fixture for a vacuum coating machine that can be quickly installed, has high stability, and is easy to use.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A loading fixture for a vacuum coating machine includes a base plate and four support blocks. The support blocks are arranged diagonally on the base plate. The support blocks are fixedly connected to support rods, which are fixed to guide rods. Four guide blocks are fixed diagonally to the base plate. The guide blocks have guide holes formed therein. The guide rods slideably engage with the guide holes. The ends of the guide rods, away from the support rods, pass through the guide holes and are fixed to pull rings. The pull rings are connected to pull ropes, and the ends of the pull ropes not connected to the pull rings are fixedly connected to handles. The guide rods are sleeved with compression springs, which are located between the support blocks and the guide blocks. Thus, when coating a housing having a groove, the groove is aligned with the base plate, and the handle is pulled, which compresses the compression springs, causing the four support blocks to move closer together, covering the housing outside the four support blocks. Release the handle, and the compression springs return to their original position, driving the support blocks to tighten the housing, thereby enabling loading. The support blocks can be configured to conform to the shape of the product. The provision of compression springs avoids the complexity of directly using a contoured mold to load the housing, thereby improving loading efficiency.

[0007] Among them, four guide wheels are rotatably installed on the base plate, and the guide wheels are provided with guide grooves for guiding the pull ropes.

[0008] Wherein, a T-shaped guide rail is fixed to the lower end of the base plate, and the handle is provided with a T-shaped groove which is slidably matched with the T-shaped guide rail.

[0009] Wherein, a plurality of limiting columns are fixedly installed on the base plate.

[0010] Wherein, two positioning columns are fixed on one end of the base plate facing away from the limiting column, and a stud is fixed on one end of the base plate facing away from the limiting column.

[0011] In summary, the loading fixture for the vacuum coating machine has the advantages of being able to be quickly installed, having high stability, and being easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic structural diagram of a loading fixture for a vacuum coating machine according to the present invention.

[0016] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0017] like Figure 1-4 As shown, a loading fixture for a vacuum coating machine includes a substrate 1 and four support blocks 2, the support blocks are arranged in the diagonal direction of the substrate, the support blocks are fixedly connected to support rods 3, the length of the support rods is set according to actual needs, the support rods are fixed with guide rods 4, and four guide blocks 5 are fixed to the substrate along the diagonal direction, the guide blocks are provided with guide holes, the guide rods slide in conjunction with the guide holes, the end of the guide rod away from the support rod passes through the guide hole and is fixed with a pull ring 6, the pull ring is connected to a pull rope 7, the end of the pull rope not connected to the pull ring is fixedly connected to a handle 8, and a compression spring 9 is sleeved on the guide rod, and the compression spring is located between the support rod and the guide block.

[0018] Thus, when coating a housing 100 having a groove, the groove is aligned with the substrate, the handle is pulled, the compression spring is compressed, the four support blocks are brought closer together, and the housing is covered outside the four support blocks. The handle is released, the compression spring is reset, and the support blocks tighten the housing, allowing the housing to be loaded. The support blocks can be contoured to the product shape. The provision of compression springs avoids the complexity of directly setting a contouring mold to load the housing, thereby improving loading efficiency.

[0019] In this embodiment, four guide wheels 10 are rotatably mounted on the base plate, and the guide wheels are provided with guide grooves for guiding the pull ropes, so as to facilitate the guidance of the pull ropes.

[0020] In this embodiment, a T-shaped guide rail 11 is fixed to the lower end of the base plate, and the handle is provided with a T-shaped slot that slides with the T-shaped guide rail to facilitate guiding the movement of the handle.

[0021] In this embodiment, a plurality of limiting posts 12 are fixedly mounted on the base plate to facilitate limiting the position of the housing.

[0022] In this embodiment, two positioning posts 13 are fixed to the end of the substrate facing away from the limiting posts, and studs 14 are fixed to the end of the substrate facing away from the limiting posts. This facilitates quick connection with the coating machine bracket. The positioning posts are inserted into the positioning holes on the coating machine bracket, and the studs pass through the coating machine bracket and connect with nuts, improving the stability of the substrate installation.

[0023] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
