Description

Technical Field

[0002] Coating equipment is mainly used to coat a thin film on the surface of different materials to improve the performance of the material or achieve specific functions. At present, in the coating process, common coating equipment adopts sputtering coating method, using sputtering coating head to coat the substrate. The principle is that in the vacuum chamber, the sputtering coating head generates glow discharge by applying negative voltage to the target. When the electrons are accelerated to fly to the substrate under the action of the electric field, they collide with argon atoms and ionize Ar+ ions and another electron. These electrons and ions bombard the target material, causing the target atoms to escape and fly to the substrate to form a thin film. The magnetic field can change the direction of electron movement and increase the probability of electron ionization of the working gas.

[0003] In the prior art, in the process of coating flexible substrates, since many flexible substrates that need to be processed are of different models and sizes, the traditional flexible substrate positioning operation is inconvenient and wrinkles are prone to occur. During the coating process, the film layer is prone to uneven depth and thickness. At the same time, the positioning bracket for positioning the flexible substrate is often large in size, which also causes the entire coating equipment to be large and not compact enough. Therefore, the coating process is inconvenient to operate and the coating effect is not good.

[0022] The embodiment of the present application provides an antibacterial coating device and method for flexible substrates, thereby solving the problem that in the prior art, during the coating process of flexible substrates, since many flexible substrates that need to be processed are of different models and sizes, the traditional flexible substrate positioning operation is inconvenient and wrinkles are prone to occur. During the coating process, the film layer is prone to uneven depth and thickness. At the same time, the positioning bracket for positioning the flexible substrate is often large in size, which also leads to the problem that the entire coating equipment is large in size and not compact enough.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The device facilitates the fixing of the substrate body 10 on the positioning ring plate 51 through the design of the embedding groove 511 and the limiting assembly 9. During operation, the substrate body 10 is wound around the positioning ring plate 51 so that the two ends of the substrate body 10 are clamped in the embedding groove 511 and the sleeve 91, and then the screw rod 92 is rotated so that the screw rod 92 drives the clamping block 93 to move, and the clamping block 93 clamps the substrate body 10 to limit its position.
