[0002] Scratch-resistant modified films are thin film materials that have undergone special modification treatment and possess excellent scratch resistance. During the production and processing of modified films, to improve their scratch resistance, a protective film or other materials are usually coated onto the substrate. During the coating operation, to ensure the protective film material is evenly coated on the substrate surface and to guarantee that the coating quality and film thickness meet requirements, a spin coating device for scratch-resistant modified films is needed. However, current spin coating devices still have the following shortcomings:
[0003] For example, patent document CN218282442U discloses a spin coating drying device. This spin coating drying device can achieve controllable heating temperature and uniform heating, which is conducive to the rapid and uniform drying of the film and improves production efficiency. However, it is not convenient to automatically open and close the seal, the operation is not convenient, and the sealing effect is poor.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a spin coating device for scratch-resistant modified film. Summary of the Invention

The lifting assembly is disposed on the surface of the fixed seat, and the lifting assembly includes a servo motor, a threaded screw, a connecting support plate, a limiting rod, an electric push rod, a limiting support ring, and a sealing cover. The servo motor is disposed on the inner surface of the fixed seat, and the output end of the servo motor is connected to the threaded screw through a coupling. The outer surface of the threaded screw is threadedly connected to the connecting support plate. A limiting rod is installed on the upper surface of the left end of the fixed seat, and the bottom of the limiting rod is tightly connected to the upper surface of the left end of the fixed seat.
[0007] Furthermore, an electric push rod is installed on the inner side of the front end of the connecting support plate, and a limit support ring is provided on the outer surface of the electric push rod.
[0008] Furthermore, a sealing cover is installed at the bottom of the electric push rod, and the sealing cover and the electric push rod are an integral structure that is tightly connected.
[0009] Furthermore, a controller is installed on the left end of the upper surface of the fixed base plate, and a support plate is installed on the upper surface of the controller.
[0010] Furthermore, a coating sealing cavity is installed on the upper surface of the support plate, and an annular sealing groove is formed on the upper surface of the coating sealing cavity.
[0011] Furthermore, a sealing ring is engaged with the inner side of the annular sealing groove, and the upper surface of the sealing ring is connected to the lower surface of the sealing cover.
[0012] Furthermore, the controller is equipped with a rotating component for rotary coating, and the rotating component includes a stepper motor, a threaded fastener and a snap-fit reinforcement groove.

[0015] 1. This utility model incorporates a lifting assembly, which includes a servo motor, a threaded screw, a connecting support plate, a limiting rod, an electric push rod, a limiting support ring, and a sealing cover. In use, the servo motor is activated, causing the threaded screw to rotate. This, in turn, moves the connecting support plate up and down along the surface of the threaded screw. During this movement, the connecting support plate slides along the surface of the limiting rod. The sliding connection between the limiting rod and the connecting support plate limits the lifting and lowering of the connecting support plate. The limiting support ring fixes the electric push rod to the left end of the connecting support plate. The connecting support plate then drives the sealing cover to rise and fall, enabling the device to automatically lift and open / close the sealing cover, making operation more convenient.

The internally threaded connecting cylinder connects to the threaded fastener, linking the support base plate to the stepper motor output. Simultaneously, the snap-fit reinforcement member engages with the inner side of the snap-fit reinforcement groove, further reinforcing the connection. This allows for rapid disassembly and assembly of the internal structure, facilitating internal cleaning. Attached Figure Description

A sealing cover 307 is installed at the bottom of the electric push rod 305, and the sealing cover 307 and the electric push rod 305 are an integrated structure that is tightly connected.
[0024] The specific operation is as follows: When in use, start the servo motor 301, which drives the threaded screw 302 to rotate, further driving the connecting support plate 303 to move up and down along the surface of the threaded screw 302. During the movement of the connecting support plate 303, it will slide along the surface of the limiting rod 304. Through the sliding connection between the limiting rod 304 and the connecting support plate 303, the lifting and lowering of the connecting support plate 303 is limited. The electric push rod 305 is fixed to the left end of the connecting support plate 303 through the limiting support ring 306. The connecting support plate 303 can drive the sealing cover 307 to rise and fall. Through the locking connection between the sealing ring 8 and the inner side of the annular sealing groove 7, the coating sealing cavity 6 is further sealed.
[0025] Please refer to Figures 3 to 4A controller 4 is mounted on the left end of the upper surface of the fixed base plate 1, and a support plate 5 is mounted on the upper surface of the controller 4.

At the same time, the snap-fit reinforcement part 904 is engaged with the inner side of the snap-fit reinforcement groove 903 to further reinforce the connection. The film substrate is placed on the support base plate 906, and a protective film material is dripped onto the surface of the film substrate. Then, the servo motor 301 is started, causing the servo motor 301 to drive the threaded screw 302 to rotate, further driving the connecting support plate 303 along the surface of the threaded screw 302. As the surface moves up and down, the connecting support plate 303 slides along the surface of the limiting rod 304 during its movement. The sliding connection between the limiting rod 304 and the connecting support plate 303 limits the lifting and lowering of the connecting support plate 303.
