Therefore, a plurality of equally spaced cutting channels (such as the cutting channels 40 shown in fig. 2B) parallel to the direction a and a plurality of equally spaced cutting channels (not shown) parallel to the direction B can be generated, that is, a plurality of cutting channels perpendicular to each other can be generated, and the large-area adhesive material 20 on the substrate 10 can be further cut into a plurality of small-area grid-shaped adhesive materials, and the small-area adhesive materials are completely separated from each other independently. The inventor finds that the large-area rubber material is cut into the rubber material with a smaller area, the phenomenon that the whole rubber material is directly peeled off to wind the roller can be avoided, the adhesive force of the rubber material is reduced in the subsequent liquid medicine spraying process, and the performance of the system is further improved.
According to an embodiment of the present invention, referring to fig. 2a and 2b, a chemical solution spraying unit 200 is provided to spray a chemical solution on the substrate 10 subjected to the cutting process. The liquid medicine spraying unit includes a liquid supply pipe assembly 210 and a liquid medicine spray head assembly 220, and the liquid supply pipe assembly 210 can supply liquid medicine to the liquid medicine spray head assembly 220 so that the liquid medicine acts on the cut rubber material 20 to reduce the adhesion of the rubber material 20 to the substrate 10. Specifically, the substrate 10 flows along the direction a, the chemical liquid spray head 220 sprays the chemical liquid on the surface of the rubber material 20, and the chemical liquid can enter the lower surface of the rubber material 20 through the cutting channel, so that the adhesive force between the rubber material 20 and the substrate 10 is reduced under the action of the chemical liquid. The inventor finds that by spraying the chemical solution on the surface of the rubber material 20 on the substrate 10 by using the chemical solution spraying unit 200, the chemical solution can enter the lower surface of the rubber material 20 in contact with the substrate 10 through the cutting channel between the rubber materials with small area, and the adhesive force between the rubber material 20 and the substrate 10 can be reduced under the action of the chemical solution.

According to an embodiment of the present invention, referring to fig. 2a and 2b, the peeling apparatus 2000 includes: a temperature control unit 300, and the aforementioned brush roller unit 400. According to the embodiment of the invention, the substrate after the cutting process and the chemical liquid spraying process can be subjected to the temperature control unit 300 to control the temperature of the environment where the substrate 10 is located, and then the rubber material 20 can be peeled off under the action of the brush roller unit 400.

The temperature control unit 300 further includes: the heating assembly 310 and the cooling assembly 320 are respectively used for heating or cooling the substrate 10. Therefore, the adhesive force of the rubber material can be reduced, and the success rate of rubber material stripping and the effect of rubber material stripping are further improved. The inventors found that in the field of manufacturing display devices, the adhesive material to be peeled off from the substrate is a temperature-sensitive adhesive material, such as a flexible temperature-controlled adhesive material, and the adhesion force of the adhesive material to the substrate has a close correlation with temperature change. More specifically, when the glue material is a high-temperature control glue material, the glue material is heated, and when the glue material reaches a certain temperature, the adhesive force of the glue material is greatly reduced; when the glue material is a low-temperature control glue material, the glue material is cooled, and when the temperature is reduced to a specific temperature, the adhesive force of the glue material is greatly reduced. Therefore, the heating assembly 310 and the cooling assembly 320 in the system can heat or cool the adhesive material according to the type of the adhesive material 20 sensitive to temperature, that is, the corresponding relationship between the adhesive force of the adhesive material and the temperature, so as to reduce the adhesive force between the adhesive material and the substrate to the maximum extent, and further improve the success rate and the peeling effect of the system for peeling the adhesive material.

Specifically, when gluing material 20 and gluing the material for high temperature, refrigeration component 320 closed, and heater 311 starts, heats the clean water, and the clean water after the heating sprays to gluing the material surface by water shower 314 to glue the material and heat.

Therefore, the adhesive force of the adhesive material is greatly reduced under the action of hot water or cold water, and the adhesive material is favorably and smoothly peeled. In addition, the heating treatment and the refrigerating treatment can be performed synchronously with the peeling treatment of the brush roller unit 400, that is, the brush roller unit 400 can peel the rubber material 20 under the condition of hot water or cold water spraying, so that the peeling success rate and the peeling effect are further improved. According to an embodiment of the present invention, the specific temperature of the heating treatment and the temperature reduction treatment is not particularly limited, and those skilled in the art can select the temperature according to the type of the glue material to be peeled, for example, the temperature of the heating treatment may be 30 to 60 degrees celsius, and the temperature of the temperature reduction treatment may be-15 to 10 degrees celsius. The inventors have found that under the above temperature range conditions of the heating treatment and the cooling treatment, i.e., the heated or cooled water is sprayed onto the surface of the rubber material 20 through the water spray heads 314, on one hand, the adhesion of the rubber material 20 can be reduced, on the other hand, the impact of the water on the surface of the rubber material 20, especially the impact of the water on the rubber material 20 at a high speed and a large flow rate, and the stripping effect of the rubber material can be greatly improved under the synergistic effect of the stripping effect of the brush roller unit 400.
