Description
Technical Field
[0001] This utility model relates to the field of coating cage technology, and in particular to an improved vacuum coating cage. Background Technology
[0002] Vacuum coating cages are the core devices used to fix and support workpieces in the vacuum coating process. Typically, a workpiece plate is placed on the cage, and the workpiece is then coated by the vacuum coating machine. After prolonged use, dust generated during coating can accumulate on the cage, and this dust falling onto the workpiece can affect the coating quality.
[0003] However, some workpiece plates on the market are placed on the cage using a U-shaped groove. This design may cause dust / dust from the U-shaped groove to fall onto the workpiece during installation, thus affecting the coating quality when installing or removing such workpiece plates.
[0004] For example, Chinese patent application number CN201620822109.8 discloses a cage frame in a vacuum coating machine. The vacuum coating machine includes a rotatable frame with a U-shaped groove at its upper end for holding the cage frame in place. The lower end of the frame has a rotatable frustum supporting the cage frame. A bearing is located at the upper end of the cage frame, and the outer diameter of the bearing is the same as the opening width of the U-shaped groove. In this design, the cage frame acts as a workpiece plate, and installation is completed by holding the cage frame in the U-shaped groove. This design requires lifting the workpiece during cage frame installation and then securing the upper and lower ends of the cage frame into the corresponding U-shaped grooves. During workpiece plate installation, dust / dust from the U-shaped groove may fall onto the workpiece, thus affecting the coating quality due to the frequent installation and removal of the workpiece plate.

[0032] The back of the workpiece plate 20 is suspended on the hanging rail 120 and can slide on the hanging rail 120. This design makes the assembly of the tooling plate simpler and can prevent dust / dust from falling on the workpiece, which helps to ensure the quality of the coating.
[0033] This application provides an improved vacuum coating cage, including a cage body 10 and a workpiece plate 20. A hanging rail 120 is provided on the cage body 10. A suspension part 21 is provided on the back of the workpiece plate 20. The suspension part 21 is hung on the hanging rail 120 and can slide on the hanging rail 120. A first bending part 23 is provided on the left side of the workpiece plate 20, and a second bending part 24 is provided on the right side. Adjacent workpiece plates 20 are closed together, with the first bending part 23 and the second bending part 24 abutting against each other. The workpiece plate 20 can be made of a suitable material, such as stainless steel or other magnetically adsorbable metal plates, and the workpiece can be magnetically attached to the workpiece plate 20. The workpiece can also be attached to the workpiece plate 20 in other ways, such as by suction cups. The suspension part 21 can be attached to the back of the workpiece plate 20 by screws, connectors, welding, etc. The workpiece plate 20 has a curved shape, and multiple workpiece plates 20 can be assembled together to form a cylindrical shape. The first bend 23 and the second bend 24 abut together, preventing dust and other contaminants from entering the cage body 10 and helping to maintain the cleanliness of the equipment's interior. During workpiece plate assembly, workers or robots lower the workpiece plate 20 onto the cage body 10 from bottom to top, allowing the suspension part 21 to hang on the rail 120. This assembly method is very simple and efficient. After the workpiece plates 20 are assembled, pushing them eliminates the gaps between them, causing the first bend 23 and the second bend 24 to abut together, preventing dust from entering the cage body 10 and helping to maintain the cleanliness of the cage.
[0034] Preferably, the cage body 10 includes a main shaft 110, an upper top plate 13, a lower top plate 15, and a support rod 17. The upper top plate 13 is disposed at the upper end of the main shaft 110, and the lower top plate 15 is disposed at the lower end of the main shaft 110. The support rod 17 connects the upper top plate 13 and the lower top plate 15. The hanging rail 120 is disposed on the support rod 17. A first connecting member (not shown in the figure) is provided between adjacent upper top plates 13 to connect them. A second connecting member 14 is provided between adjacent lower top plates 15 to connect them. The first connecting member (not shown in the figure) and the second connecting member 14 can be plate-shaped. The upper top plate 13, the lower top plate 15, and the main shaft 110 are assembled together by screws or bolts; the upper top plate 13 and the lower top plate 15 are mounted on the support rod 17 by screws; the first connecting piece (not shown in the figure) splices the upper top plate 13 together by screws; the second connecting piece 14 splices the lower top plate 15 together by screws; the hanging rail 120 is mounted on the support rod 17 by the third connecting piece; in this way, the cage body 10 can be assembled into a whole, with good structural stability and fewer required accessories.
[0035] Preferably, the spindle 110 has a hollow structure, and cleaning ports 11 are symmetrically arranged on its upper and lower ends. The hollow interior of the spindle 110 reduces its weight, and the cleaning ports 11 facilitate cleaning the interior of the spindle 110 using a vacuum cleaner. In this embodiment, two cleaning ports 11 are symmetrically arranged on each of the upper and lower ends of the spindle 110, allowing workers to clean the interior of the spindle 110 from multiple angles.
[0036] Preferably, the support rod 17 is provided with a plurality of first weight-reducing holes 18; the upper top plate 13 and the lower top plate 15 are structured in a fan shape or fan ring shape, and both the upper top plate 13 and the lower top plate 15 are provided with second weight-reducing holes 16. The first weight-reducing holes 18 and the second weight-reducing holes 16 can reduce the weight of the cage frame body 10, making it easier to assemble and transport the cage frame body 10. The fan shape or fan ring shape of the upper top plate 13 and the lower top plate 15 allows each of the upper top plate 13 and the lower top plate 15 to be assembled into a circle, which is a very ingenious assembly structure.
[0037] Preferably, the hanging rail 120 includes a mounting plate 121 and a first hanging plate 122 formed by bending the mounting plate 121; the suspension part 21 is hung on the first hanging plate 122; the mounting plate 121 is mounted on the support rod 17 via a third connector 19. The hanging rail 120 can be formed by stamping aluminum or stainless steel plate. The third connector 19 can be L-shaped. During assembly of the hanging rail 120, the third connector 19 is installed on the support rod 17 with screws; then the third connector 19 supports the mounting plate 121, and the screws assemble the mounting plate 121 and the third connector 19 together, thus completing the assembly of the hanging rail 120. This assembly structure is very simple.
[0038] Preferably, the hanging rail 120 has a circular ring structure; the suspension part 21 has an arc structure, and a second hanging plate 22 is formed by bending on the arc structure; the second hanging plate 22 is hung on the first hanging plate 122. The hanging rail 120 can be a circular ring structure spliced from multiple segments, or it can be a circular ring structure as a whole. In this embodiment, the hanging rail 120 is spliced from multiple segments, which facilitates assembly. Specifically, the hanging rail 120 is an arc-shaped plate. The hanging rail 120 can be stamped from stainless steel plate or aluminum alloy plate. When assembling the workpiece plate 20, the second hanging plate 22 is hung on the first hanging plate 122, so that the suspension part 21 can be directly suspended on the hanging rail 120. This assembly structure is very simple and convenient.
[0039] Preferably, the first bending portion 23 has an L-shape, and the second bending portion 24 has a rectangular shape. When adjacent workpiece plates 20 are closed, the first bending portion 23 and the second bending portion 24 will close together. This structure can prevent dust / dust and other particles from entering the cage body 10. The first bending portion 23 and the second bending portion 24 are formed by stamping. The L-shape of the first bending portion 23 and the rectangular shape of the second bending portion 24 facilitate the closure of the connected workpiece plates 20. The bending path between the first bending portion 23 and the second bending portion 24 effectively prevents dust / dust and other particles from entering the cage.
[0040] Preferably, the back of the workpiece plate 20 is provided with a plurality of first reinforcing ribs 25 laterally and a plurality of second reinforcing ribs 26 longitudinally, the first reinforcing ribs 25 and the second reinforcing ribs 26 interlocking together. The first reinforcing ribs 25 and the second reinforcing ribs 26 can be plate-shaped. The first reinforcing ribs 25 and the second reinforcing ribs 26 can be installed on the back of the workpiece plate 20 by welding or screwing. The cooperation of the first reinforcing ribs 25 and the second reinforcing ribs 26 can enhance the strength of the workpiece plate 20 and prevent its deformation. The first reinforcing ribs 25 and the second reinforcing ribs 26 interlocking and then welding together provides a very strong assembly process.
[0041] Preferably, handles 27 are provided on the upper and lower ends of the front side of the workpiece plate 20. The handles 27 facilitate workers or robots to move the workpiece plate 20.
[0042] Preferably, the cage body 10 is provided with at least two hanging rails 120; the workpiece plate 20 is provided with at least two suspension parts 21. The number of hanging rails 120 and suspension parts 21 can be set as needed.
[0043] In summary, the key design feature of this invention is that the suspension part 21, suspended on the hanging rail 120, allows for the installation of the workpiece plate 20. Simultaneously, the suspension part 21 is located on the back of the workpiece plate 20, preventing dust / dust from falling onto the workpiece and ensuring the coating quality. The workpiece plate 20 can be closed together by sliding on the hanging rail 120, facilitating position adjustment. The first bending part 23 and the second bending part 24 abut against each other, preventing coating dust / dust from entering the cage body 10 and contributing to the cleanliness of the equipment.
