Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a material rack for a vacuum coating machine. Background Technology

[0002] Vacuum coating machines mainly refer to a type of coating equipment that needs to be carried out under high vacuum. The specific coating methods include vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, and many others. Evaporation and sputtering are the most commonly used. Evaporation coating generally involves heating the target material to evaporate the surface components in the form of atomic groups or ions, which then settle on the substrate surface and form a thin film after undergoing the film formation process.

[0003] During the use of a vacuum coating machine, the product to be coated needs to be placed on a rack. Currently used racks include a turntable, a base coaxially fixed to the turntable via a connecting rod, and several hanging rods arranged around the turntable. Each hanging rod has hooks for suspending the product. The turntable and base have corresponding insertion holes, and a tray is fixed to the lower end of the base. When the product is suspended on the hooks, the operator holds the hanging rod at an angle, making it easy for the product to fall off. The operator then passes the upper end of the hanging rod through the insertion hole on the turntable and rotates it to a vertical position before lowering it, allowing it to pass through the insertion hole on the base and contact the tray. The vacuum coating machine is equipped with a drive motor to rotate the turntable. During the start-up and stop of the turntable, because the size of the insertion hole is larger than the size of the hanging rod and there is no limiting structure for the hanging rod, the hanging rod is prone to wobbling, which can also cause the product to fall off the hook. This results in poor stability and fails to meet the usage requirements. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a vacuum coating machine material rack that is highly stable, practical, and easy to operate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A vacuum coating machine material rack includes a turntable, a base, a rotating shaft, and several hanging rods; the two ends of the rotating shaft are fixedly connected to the turntable and the base respectively, and the rotating shaft, the turntable, and the base are coaxially arranged; the base has several blind holes that can be inserted and mated with the hanging rods; the turntable has two spaced hooks fixedly installed opposite each blind hole; the upper ends of the hanging rods have protrusions on both sides that can be hooked with the hooks.

[0007] A slip ring is slidably fitted on the rotating shaft. Several radially arranged support arms are fixedly installed on the slip ring around its circumference. The outer ends of the support arms are all fixedly connected to the ring. A pressure block is provided protruding from the ring between the two hooks. An upper locking structure is installed between the disc and the turntable, and a lower locking structure is provided between the slip ring and the rotating shaft.

[0008] In this way, the product to be coated is connected to the hooks circumferentially set on the hanging rod. The operator holds the hanging rod vertically, aligning the upper end of the rod with the space between the two hooks and the protrusion with the hook. The operator moves the hanging rod downwards, inserting the lower end of the rod into the blind hole, with the protrusion inside the hook, thus completing the installation of a single hanging rod. After all hanging rods are installed, the operator moves the ring downwards, pressing the pressure block against the upper end of the hanging rod, using the lower locking structure to limit the position of the hanging rod. After coating is completed, the operator moves the ring upwards, using the upper locking structure to move the ring upwards until it is in contact with the turntable, after which the operator can remove the hanging rod.

[0009] The upper locking structure includes several upper magnets, the inner ring is recessed to form an upper groove, the upper magnets are fixedly installed in the upper groove, the ring is made of ferromagnetic metal, and the upper magnets can be attracted to the turntable.

[0010] The lower locking structure includes a limiting ring fixedly installed on the rotating shaft. The limiting ring is made of ferromagnetic metal. The lower end of the slip ring has a lower groove, and a lower magnet is fixedly installed in the lower groove. The lower magnet can be attracted to the limiting ring.

[0011] The upper end of the ring is fixedly installed with a guide pin, and the turntable has a guide hole that slides with the guide pin.

[0012] A reinforcing rib is fixedly installed between the support arm and the slip ring.

[0013] The circular ring is fixedly fitted with several handles facing downwards.

[0014] In summary, the material rack of this vacuum coating machine has the advantages of high stability, strong practicality, and simple operation. Attached Figure Description

These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0023] like Figure 1-7 As shown, a vacuum coating machine material rack includes a turntable 1, a base 2, a rotating shaft 3, and several hanging rods 4; the two ends of the rotating shaft are fixedly connected to the turntable and the base respectively, and the rotating shaft, the turntable, and the base are coaxially arranged; the base has several blind holes that can be inserted and matched with the hanging rods; the turntable has two spaced hooks 5 fixedly installed opposite each blind hole; the upper ends of the hanging rods have protrusions 6 on both sides that can be hooked with the hooks;

[0024] A slip ring 7 is slidably fitted on the rotating shaft. Several radially arranged support arms 8 are fixedly installed on the slip ring around its circumference. The outer ends of the support arms are all fixedly connected to a circular ring 9. A pressure block 10 is provided protruding between the two hooks on the circular ring. An upper locking structure is installed between the disc and the turntable, and a lower locking structure is provided between the slip ring and the rotating shaft.

[0025] In this way, the product to be coated is connected to the hooks circumferentially set on the hanging rod. The operator holds the hanging rod vertically, aligning the upper end of the rod with the space between the two hooks and the protrusion with the hook. The operator moves the hanging rod downwards, inserting the lower end of the rod into the blind hole, with the protrusion inside the hook, thus completing the installation of a single hanging rod. After all hanging rods are installed, the operator moves the ring downwards, pressing the pressure block against the upper end of the hanging rod, using the lower locking structure to limit the position of the hanging rod. After coating is completed, the operator moves the ring upwards, using the upper locking structure to move the ring upwards until it is in contact with the turntable, after which the operator can remove the hanging rod.

[0026] The turntable is coaxially and fixedly connected to the output shaft of the drive motor mounted on the upper end of the vacuum coating machine via a coupling. The base is connected to the vacuum coating machine via bearings, which is the existing installation method. Several hooks are provided around the circumference of the hanging rod. The hooks are connected to the hanging rod by bolts or welding, which is not shown in the figure and represents the existing installation method. The product to be coated can be hung on the hooks on the hanging rod.

[0027] When the ring is in contact with the turntable, the distance between the pressure block and the open end of the hook allows the protrusion to pass through.

[0028] In implementation, the upper locking structure includes several upper magnets 11. The ring is recessed to form an upper groove, and the upper magnets are fixedly installed in the upper groove. The ring is made of ferromagnetic metal, and the upper magnets can be attracted to the turntable. This facilitates fixing the position of the ring.

[0029] In implementation, the lower locking structure includes a limiting ring 12 fixedly mounted on the rotating shaft. The limiting ring is made of ferromagnetic metal, and a lower groove is formed at the lower end of the slip ring. A lower magnet is fixedly mounted in the lower groove, and the lower magnet can engage with the limiting ring. This facilitates the fixing of the position of the pressure block.

[0030] Ferromagnetic metals include a variety of metals, such as iron, nickel, and cobalt, as well as their alloys, such as various steels (low-carbon steel, silicon steel, etc.), AlNiCo, NdFeB, SamariumCo, etc., which are selected according to actual needs.

[0031] In practice, a guide pin 13 is fixedly installed at the upper end of the ring, and a guide hole 14 is provided on the turntable to slide with the guide pin. This facilitates the guiding of the ring's lifting and lowering.

[0032] During implementation, a reinforcing rib plate 15 is fixedly installed between the support arm and the slip ring to improve installation strength.

[0033] In practice, several handles 16 are fixedly installed downwards on the ring to facilitate its movement.

[0034] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
