Abstract
Description
Technical Field
[0001] This utility model relates to the field of sputtering coating technology, specifically to a sputtering coating device capable of maintaining vacuum. Background Technology
[0002] Magnetron sputtering is a type of physical vapor deposition. General sputtering methods can be used to prepare various materials such as metals, semiconductors, and insulators, and have advantages such as simple equipment, easy control, large coating area, and strong adhesion. Magnetron sputtering, in particular, achieves high speed, low temperature, and low damage. Because high-speed sputtering is performed under low pressure, it is essential to effectively increase the ionization rate of the gas. Magnetron sputtering increases plasma density and sputtering speed by introducing a magnetic field onto the target cathode surface and using the magnetic field to confine charged particles. An existing sputtering coating apparatus capable of maintaining vacuum (publication number: CN205529009U) exhibits at least the following defects during use:
[0003] The above scheme creates a vacuum environment for the coating process by setting up a vacuum pump and adjusts the position of the substrate by flipping the cover plate. However, in actual use, the position of the substrate will move in a circular motion due to the flipping of the cover plate, causing the incompletely solidified coating to flow and affecting the coating quality. Therefore, a sputtering coating device that can maintain the vacuum level needs to be developed. Summary of the Invention
[0004] The main objective of this invention is to provide a sputtering coating device that can maintain a vacuum level, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A sputtering coating apparatus capable of maintaining vacuum includes a coating housing. Multiple sets of lifting slide columns are fixedly connected to the outer edge of the coating housing. A lifting cover plate is slidably connected to the side of all the lifting slide columns facing the coating housing. The bottom side of the lifting cover plate is in close contact with the top side of the coating housing. A lifting connecting column is fixedly connected to the bottom side of the lifting cover plate. A substrate clamping frame is fixedly connected to the bottom side of the lifting connecting column. A coating substrate is mounted on the bottom side of the substrate clamping frame. A coating nozzle is fixedly connected to the inner wall of the bottom side of the coating housing.
[0007] Preferably, a limiting plate is fixedly connected to the top side of each set of lifting slide columns, and one side of each limiting plate extends to the side of the corresponding lifting slide column facing the coating shell. A rotating block is rotatably connected between the opposite sides of the top of each set of lifting slide columns.
[0008] Preferably, each of the rotating blocks has a pushing ramp on its bottom side, and each of the rotating blocks has a latch on the side facing the coating shell. Each latch engages with the outer edge of the lifting cover plate, and each of the rotating blocks contacts the corresponding limiting plate on the side facing the coating shell.
[0009] Preferably, each set of lifting slide columns has a locking turntable on the side facing away from the coating shell, and each rotating block has another locking turntable on the side facing away from the coating shell, with multiple pushing springs between the corresponding two locking turntables.
[0010] Preferably, a coating bottom frame is fixedly connected to the bottom side of the coating shell, and one end of the coating nozzle is connected to the outside of the coating bottom frame.
[0011] Preferably, a ring of No. 1 electromagnets is fixedly connected to the bottom side of the lifting cover plate, and a ring of No. 2 electromagnets is fixedly connected to the inner wall of the bottom side of the coated bottom frame.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The lifting slide column allows workers to smoothly raise and lower the lifting cover plate, while simultaneously allowing the coating substrate connected to the lifting cover plate to rise and fall smoothly in sync. This ensures that the coating remains stable during handling and does not flow along the substrate surface, thus guaranteeing a stable coating thickness. Additionally, the rotating locking block secures the lifting cover plate, exposing the coating substrate for easy substrate replacement by workers. Attached Figure Description
