[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] Reference Figure 1-6 , is an embodiment of the utility model, and provides a substrate fixing device for replacing plastic oil coating. The substrate fixing device for replacing plastic oil coating includes a base 1, the base 1 is a U-shaped structure, the two ends of the base 1 are protrusions, a processing table 2 is arranged in the concave part of the base 1, an air bag 3 is installed between the base 1 and the processing table 2, and is used to control the lifting and lowering of the processing table 2. The air bag 3 is inflated by an air pump and controlled by an air pressure control system, and can realize automatic and remote control of inflation and deflation as in the prior art. Two parallel cross bars 4 are arranged on the base 1, and the two ends of the cross bar 4 are respectively installed on the protrusions at the two ends of the base 1 and slidably connected therewith. The protruding ends of the base 1 are both installed with rails 6, and the two ends of the cross bar 4 are both installed with card blocks 7. The card blocks 7 are stuck on the rails 6 and can slide relative to the rails 6. There is no free gap between the sliding between the two. When the processing table 2 rises to the highest point, it contacts the bottom surface of the cross bar 4. The four corners of the upper end of the base 1 are fixedly installed with limit blocks 8. After the processing table 2 moves to the uppermost end, it is blocked by the limit blocks 8. The device further comprises two limiting mechanisms 5 , which are slidably arranged on the two cross bars 4 , and the limiting mechanisms 5 are arranged perpendicular to the two cross bars 4 .
[0027] The limiting mechanism 5 includes a longitudinal rod 501, and a slider 502 is slidably provided at the bottom of both ends of the longitudinal rod 501. The bottom end of the slider 502 is stuck on the cross bar 4 and slidably connected thereto. There is no free gap between the slider 502 and the cross bar 4. A cushion block 503 is hinged at the middle position of the longitudinal rod 501. A compression spring 504 is installed on the slider 502. The compression spring 504 is made of alloy material. One end of the compression spring 504 connected to the slider 502 can adjust the angle relative to the slider 502. The bottom surface of the slider 502 is flush with the bottom surface of the cross bar 4, and a gasket 505 is fixedly installed on the side of the slider 502 that is close to each other. A sliding groove 506 that runs through the top and bottom is provided at the front and rear ends of the longitudinal rod 501. The upper end of the slider 502 passes through the sliding groove 506 and slides with it. When the cushion block 503 swings downward to a vertical position, it is on the same vertical plane as the gasket 505. The positions where the cushion block 503 and the gasket 505 contact the substrate are both rough surface structures. The compression spring 504 is elastic, and one end of the compression spring 504 away from the slider 502 approaches the processing table 2 and can fit therewith.
[0028] During use, after the airbag 3 is inflated, the processing table 2 can always be at the top and in contact with the cross bar 4. At this time, the bottom of the substrate is lifted up, the distance between the two cross bars 4 can be adjusted, and the distance between the two longitudinal bars 501 can also be adjusted. At the same time, the two can be adjusted in conjunction. The area between the two can be used to place the substrate, and substrates of different sizes can be placed. When the substrate has a certain hardness, the gasket 505 on the cross bar 4 and the slider 502 can achieve restriction. When the substrate is larger, the cushion block 503 can also limit the middle. When the substrate is thinner and softer, the compression spring 504 can play an auxiliary fixing effect. The compression spring 504 is used to fix different positions during spraying. When the substrate is processed, the processing table 2 is lowered to remove the substrate.
