[0002] The photosensitive material plate comprises a substrate and a layer of photosensitive liquid on the substrate. The substrate first forms an oxidation film on its surface, and then a layer of photosensitive liquid is coated on the oxidation film of the substrate to obtain the photosensitive material plate. The equipment used to form the oxidation film on the substrate is the oxidation device of the photosensitive material plate substrate.

[0003] The oxidation device of the photosensitive material plate substrate comprises an oxidation tank. The oxidation tank has an entering end on the left side and an exiting end on the right side. There are a variable-diameter roller and a conveying roller in the oxidation tank. The substrate enters the oxidation tank from the entering end, and the oxidation of the surface of the substrate is completed in the oxidation tank. The oxidized substrate exits from the exiting end. The substrate enters from the entering end, passes through the variable-diameter roller, and then exits from the exiting end to form an oxidation route. In the prior art, people always think that the oxidation liquid above the oxidation tank is clearer and contains fewer impurities. The oxidation route is arranged above the inside of the oxidation tank. The substrate obtained in this way has fewer impurities on the surface and does not need to be cleaned too much. However, the oxidation film of the substrate obtained in this way has more pinholes (i.e., pinhole-shaped non-oxidized parts), which affects the quality of the oxidation layer. SUMMARY

[0004] The purpose of the utility model is to provide a substrate oxidation device with fewer pinholes on the oxidation film and good oxidation film quality to solve the above problems.

[0005] The technical solution of the utility model is as follows: a substrate oxidation device comprises an oxidation tank. The oxidation tank has an entering end on the left side and an exiting end on the right side. There are a variable-diameter roller and a conveying roller in the oxidation tank. The substrate enters the oxidation liquid in the oxidation tank from the entering end, and the oxidation of the surface of the substrate is completed in the oxidation tank. The oxidized substrate exits from the exiting end. The substrate enters from the entering end, passes through the variable-diameter roller, and then exits from the exiting end to form an oxidation route. The feature is that one section of the oxidation route is arranged at a position close to the bottom in the oxidation tank. This section of the oxidation route is the bottom route.

[0006] Further, one section of the oxidation route is arranged at a position above the oxidation tank. This section of the oxidation route is the upper route. The oxidation route runs from back to front. The upper route is in front of the bottom route.
