Abstract
Description
Technical Field
[0001] This invention relates to the field of substrate manufacturing technology, and more specifically to an oxidation apparatus and a method for oxidizing substrates. Background Technology
[0002] A photosensitive material plate includes a substrate and a photosensitive liquid layer on the substrate.
[0003] The substrate is an aluminum substrate. Before coating the substrate with a photosensitive liquid layer, an oxide layer is also required on the substrate. The equipment used to form an oxide tank on the substrate is a substrate oxidation device.
[0004] An oxidation apparatus for a substrate includes a frame and an oxidation tank mounted on the frame. In use, the oxidation tank contains an oxidation solution, such as dilute sulfuric acid. The oxidation tank has an inlet on the left and an outlet on the right. A substrate feed roller is installed at the inlet, and a substrate receiving roller is installed at the outlet. Guide rollers for the substrate are installed inside the oxidation tank; these guide rollers are inner guide rollers. The substrate forms an oxidation path under the action of the feed roller, inner guide roller, and receiving roller. The substrate moves along the oxidation path, and an oxidation tank can be formed on the surface of the substrate. Since only one side of the substrate (i.e., the side with the photosensitive emulsion layer) needs to be oxidized for the production of photosensitive material boards, in existing technologies, there are no covering components on the sides of the oxidation path. This results in oxide layers on both sides of the produced substrate, or the oxidation degree on both sides is the same. This wastes oxidation solution, causes unnecessary damage to the substrate, and increases production costs. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing an oxidation apparatus and method for substrates that reduce waste of oxidation solution, save costs, and reduce damage to the substrate.
[0006] The technical solution of the substrate oxidation apparatus of the present invention is implemented as follows: A substrate oxidation apparatus includes an apparatus frame and an oxidation tank mounted on the apparatus frame. The oxidation tank has an inlet end on the left and an outlet end on the right. A substrate feeding roller is installed at the inlet end, and a substrate receiving roller is installed at the outlet end. Guide rollers for the substrate are installed inside the oxidation tank. These guide rollers are inner guide rollers. The substrate forms an oxidation path under the action of the feeding roller, the inner guide roller, and the receiving roller. The feature is that guide rollers are also installed on the apparatus frame on the outer periphery of the oxidation tank. These guide rollers are outer guide rollers. An annular support belt is installed on the outer guide roller. The support belt is made of rubber. The top of the support belt extends into the oxidation tank. The support belt is attached to the oxidation path and runs synchronously inside the oxidation tank. The side of the support belt that is in contact with the oxidation path is the contact surface.
[0007] Furthermore, an adhesive reservoir is also installed on the device frame. The adhesive reservoir is connected to an adhesive nozzle via a pipe. The adhesive nozzle faces the side where the backing tape and the oxidation path will be bonded, and is located behind the part that will be bonded to the oxidation path.
[0008] Furthermore, pairs of rolling rollers are installed on the device frame, with the rolling section between the two rolling rollers. The supporting belt and oxidation path are attached to the rolling section.
[0009] Furthermore, a washing tank is also installed on the device frame, and a variable diameter roller is also installed in the washing tank. This variable diameter roller is a washing variable diameter roller, and the supporting belt is also acted on in the washing tank through the washing variable diameter roller.
[0010] Furthermore, the bonding surface has protrusions on both sides.
[0011] The technical solution of the substrate oxidation method of the present invention is implemented as follows: the substrate oxidation method oxidizes the substrate by oxidizing the substrate in an oxidation tank, so that an oxidized surface is formed on the substrate, and the side opposite to the oxidized surface is the bottom surface. The characteristic is that, during the oxidation process, a cover film is attached to the bottom surface of the substrate.
[0012] Furthermore, an adhesive is also filled between the substrate and the cover film.
[0013] To elaborate further, the adhesive is glycerin.
[0014] Furthermore, a rolling roller is used to roll the substrate and the cover film, making the substrate and the cover film bond more tightly.
[0015] Furthermore, after oxidizing the substrate surface, the cover film is removed and then washed.
[0016] The beneficial effects of the present invention are that such an oxidation apparatus and method for substrates have the advantages of reducing waste of oxidation liquid, saving costs, and reducing damage to the substrate. Attached Figure Description

Detailed Implementation
[0020] In the description of the preferred embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate link; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0021] To better understand this invention, the following description, in conjunction with the accompanying drawings, will provide further details.
[0022] like Figure 1 , 2 As shown, an oxidation apparatus for a substrate includes a frame 1 and an oxidation tank 2 mounted on the frame. The oxidation tank has an inlet end on the left and an outlet end on the right. A substrate feed roller 11 is mounted at the inlet end, and a substrate receiving roller 12 is mounted at the outlet end. Guide rollers for the substrate are mounted inside the oxidation tank. These guide rollers are inner guide rollers 31. The substrate forms an oxidation path 4 under the action of the feed roller, the inner guide roller, and the receiving roller. The apparatus is characterized by: guide rollers 32 are also mounted on the frame around the oxidation tank. These guide rollers are outer guide rollers 32. An annular support belt 5 is mounted on the outer guide roller. The support belt is made of rubber and extends into the oxidation tank. The support belt is attached to the oxidation path and runs synchronously inside the oxidation tank. The side of the support belt that is in contact with the oxidation path is the contact surface.
[0023] In the present invention, the above-mentioned configuration allows the support strip to be placed under the substrate during use, preventing the oxide liquid from contacting the bottom surface of the substrate 13. The support strip is a cover film formed under the substrate, which can prevent oxidation or reduce the degree of oxidation on the bottom surface of the substrate, thus achieving the purpose of the present invention.
[0024] The support tape adheres to the bottom surface of the substrate inside the oxidation tank and separates from the substrate outside the oxidation tank. The support tape rotates continuously and can be reused.
[0025] The frame is also equipped with a conveying roller for conveying the substrate 13. The conveying roller is connected to a conveying motor. The conveying roller acts on the substrate to ensure the operation of the substrate on this device.
[0026] Furthermore, an adhesive reservoir 6 is also installed on the device frame. The adhesive reservoir is connected to an adhesive nozzle 61 via a pipe. The adhesive nozzle faces the side where the backing tape and the oxidation path will be bonded, and is located behind the part that will be bonded to the oxidation path.
[0027] In use, the adhesive container holds adhesive 62, which is a liquid adhesive. The adhesive can prevent the oxidizing liquid from entering the underside of the substrate between the substrate and the backing tape. Glycerin is preferred, which has the advantages of better preventing the oxidizing liquid from entering the underside of the substrate and does not cause deterioration of the oxidizing liquid.
[0028] The guide roller is also connected to a guide motor. The operation of the guide motor drives the guide roller to operate, ensuring the operation of the support belt.
[0029] Furthermore, there are pairs of rolling rollers 7 installed on the device frame, with the rolling section 71 between the two rolling rollers, and the supporting belt and oxidation route are attached to the rolling section.
[0030] The above-mentioned configuration of the present invention allows for a tighter bond between the support strip and the substrate.
[0031] Furthermore, a washing tank 8 is also installed on the device frame, and a variable diameter roller is also installed in the washing tank. This variable diameter roller is a washing variable diameter roller 81, and the supporting belt is also acted on in the washing tank through the washing variable diameter roller.
[0032] The above-mentioned configuration of the present invention can also enable the washing of the liner belt coming out of the oxidation tank.
[0033] Furthermore, the bonding surface has protrusions 51 on both sides.
[0034] The above-mentioned configuration of the present invention ensures that the supporting strip and the substrate have intact structures on the side, and makes it less likely for the oxide liquid to enter under the substrate.
[0035] The technical solution of the substrate oxidation method of the present invention is implemented as follows: the substrate oxidation method involves oxidizing the substrate in an oxidation tank to form an oxidized surface on the substrate, and the side opposite to the oxidized surface is the bottom surface. The characteristic is that during the oxidation process, a cover film is attached to the bottom surface of the substrate, and the cover film is formed by the aforementioned backing strip.
[0036] Furthermore, an adhesive is also filled between the substrate and the cover film.
[0037] To elaborate further, the adhesive is glycerin.
[0038] Furthermore, a rolling roller is used to roll the substrate and the cover film, making the substrate and the cover film bond more tightly.
[0039] Furthermore, after oxidizing the substrate surface, the cover film is removed and then washed.
[0040] It should be noted that the beneficial effects of the above-described embodiments of the substrate oxidation apparatus and substrate oxidation method can be explained and supplemented by each other.
[0041] This invention also provides an application of glycerol as an adhesive. When the surface of the substrate is not oxidized in the oxidation bath, a covering film is used to cover the surface, and an adhesive, namely glycerol, is filled between the surface and the oxide film. That is, during the oxidation process of the substrate in the oxidation bath, in order to oxidize one side of the substrate while leaving the other side unoxidized, a covering film is used to cover the other side of the substrate, and glycerol is filled between the substrate and the covering film as an adhesive to prevent the other side of the aluminum substrate from oxidizing.
[0042] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
