Description

Technical Field

[0001] This invention relates to the field of photosensitive material plate repair equipment technology, and also to a method for repairing defects in photosensitive material plates, specifically to a photosensitive material plate defect repair device and a photosensitive material plate defect repair method. Background Technology

[0002] A photosensitive material plate includes a substrate underneath and a photosensitive material coating on the substrate. The photosensitive material coating is formed by the solidification of a photosensitive material solution. During the production process of the photosensitive material plate, defects often occur, such as incomplete application of the solution due to air bubbles. These defects affect the quality of the photosensitive material plate and usually require repair.

[0003] Currently, there is no specialized repair equipment for repairing defective photosensitive material plates. Repairing is often done manually by applying the photosensitive material solution to the defective area using a brush and allowing it to dry naturally. This method suffers from drawbacks such as low repair efficiency, poor repair quality, and noticeable repair boundaries. Improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a device and method for repairing defects in photosensitive material plates that are simple to use, provide high-quality repairs, and address the issue of unclear repair boundaries.

[0005] The technical solution adopted by the photosensitive material plate defect repair device of the present invention is as follows: The photosensitive material plate defect repair device includes a device frame, on which a platform for placing photosensitive material plates is provided. A container for photosensitive material plate repair liquid is also installed on the device frame. The container has a repair liquid output pipe. The device is characterized in that: the repair liquid output pipe is connected to a spray head via an output pump; the spray head is mounted on the device frame via a lifting device; the spray head is connected to a control device; the lifting device is connected to the control device; a first electronic switch is also installed on the spray head or in the middle of the repair liquid output pipe; the first electronic switch is connected to the control device; the control device can control the opening degree of the first electronic switch; the control device operates as follows: the control device activates the first electronic switch, the spray head sprays repair liquid onto the defective area, and as spraying proceeds, the lifting device gradually rises. During the gradual rise of the lifting device, the control device gradually closes the first electronic switch; when the lifting device reaches a certain level, the control device completely closes the first electronic switch, and then the lifting device returns to its initial position.

[0006] In one technical solution, the device frame has a bendable cantilever, and the spray head is mounted under the cantilever.

[0007] In one technical solution, the device frame has a slide rail, and the placement platform is installed in the slide rail and can slide in the left and right or / and front and back directions.

[0008] Furthermore, the placement platform has a first temperature regulating device, and the repair fluid output pipe has a second temperature regulating device. The first and second temperature regulating devices are respectively connected to a control device. The control device can make the temperature above the placement platform and below the part targeted by the spray head, i.e., the surrounding area, reach 25-30°C. The control device can make the temperature of the repair fluid sprayed from the spray head reach 20-25°C, and the temperature of the sprayed fluid is 3-5°C lower than the temperature above the placement platform.

[0009] In one technical solution, the control device is a PLC control device, a microcontroller, or a control unit.

[0010] Furthermore, the device frame is also equipped with a refrigeration unit, which has a cold air outlet connected to a cold air output pipe. The cold air output pipe has a cold air release port. The refrigeration unit can ensure that the temperature of the air flowing out of the cold air release port reaches 5-10°C. The cold air release port is installed on the side of the spray head via a telescopic component. The telescopic component is connected to a control device, which can control the extension and retraction of the telescopic component. An electronic valve is installed in the middle of the cold air output pipe, and the valve is connected to the control device, which can control the opening degree of the electronic valve. When the lifting device completes its ascent, the control device can cause the electronic valve to gradually open and the telescopic component to gradually extend; then, the telescopic component will gradually retract and the electronic valve will gradually close.

[0011] The technical solution adopted in the photosensitive material plate defect repair method of the present invention is as follows: The photosensitive material plate defect repair method uses a repair liquid to repair the defective parts of the photosensitive material plate. The repair liquid is sprayed onto the defective parts using a spray head, and as the spraying proceeds, the spray head gradually moves away from the defective parts of the photosensitive material plate (i.e., the parts where the repair liquid is sprayed). This process is the repair liquid spraying process, and during the repair liquid spraying process, the repair liquid sprayed from the spray head gradually decreases.

[0012] Furthermore, during the repair process of the photosensitive material plate, the temperature of the defective part of the photosensitive material plate and its surrounding area is 25-30℃, the temperature of the repair liquid is 20-25℃, and the temperature of the repair liquid is 3-5℃ lower than the temperature of the defective part of the photosensitive material plate and its surrounding area.

[0013] Furthermore, after the repair liquid is applied, there is a process of blowing cold air onto the defective area. The temperature of the cold air blown onto the defective area is 5-10℃. As the cold air is blown, the air volume is gradually increased first and then gradually decreased to complete the repair of the defect on the photosensitive material board.

[0014] The beneficial effects of this invention are that the photosensitive material plate defect repair device and the photosensitive material plate defect repair method have the advantages of being simple to use, having good repair quality, and having indistinct repair boundaries.

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] like Figure 1 , 2 As shown, a photosensitive material plate defect repair device includes a device frame 1, a photosensitive material plate placement platform 2 on the device frame, and a photosensitive material plate repair liquid holding tank 3 installed on the device frame. The holding tank has a repair liquid output pipe 31. The device is characterized in that: the repair liquid output pipe is connected to a spray head 32 via an output pump; the spray head is mounted on the device frame via a lifting device 4; the spray head is connected to a control device 5; the lifting device is connected to the control device; a first electronic switch 33 is also installed on the spray head or in the middle of the repair liquid output pipe; the first electronic switch is connected to the control device, and the control device can control the opening degree of the first electronic switch. The control device operates as follows: the control device activates the first electronic switch, the spray head sprays repair liquid onto the defective area, and as the spraying proceeds, the lifting device gradually rises. During the gradual rise of the lifting device, the control device gradually closes the first electronic switch; when the lifting device reaches a certain level, the control device completely closes the first electronic switch, and then the lifting device returns to its initial position.

[0020] When using the photosensitive material plate defect repair device of the present invention, the photosensitive material plate is placed on the placement platform, with the defective area located below the spray head. The control device operates, and the liquid coating of the photosensitive material plate sprayed from the spray head falls on the defective area. During the spraying process, the spray head gradually rises, and the amount of liquid sprayed gradually decreases. In this way, there is no clear boundary between the repaired area and the original intact liquid coating, which can achieve the purpose of the present invention and improve product quality. Since the present invention uses equipment processing, it has the advantages of simple use, higher degree of automation, and convenient operation.

[0021] In one technical solution, the device frame has a bendable cantilever 11, and the spray head is installed under the cantilever.

[0022] This invention allows for easy adjustment of the spray head's position, ensuring it is accurately aimed at defective areas on different parts of the photosensitive material plate.

[0023] In one technical solution, the device frame has a slide rail 21, and the placement platform is installed in the slide rail and can slide in the left and right or / and front and back directions.

[0024] This invention allows for adjustment of the position of the photosensitive material plate on the placement platform.

[0025] Furthermore, the placement platform has a first temperature regulating device 61, and the repair fluid output pipe has a second temperature regulating device 62. The first and second temperature regulating devices are respectively connected to a control device. The control device can make the temperature above the placement platform and below the area targeted by the spray head, i.e., the surrounding area, reach 25-30°C. The control device can make the temperature of the repair fluid sprayed from the spray head reach 20-25°C, and the temperature of the sprayed fluid is 3-5°C lower than the temperature above the placement platform.

[0026] During use, the control device can ensure that the temperature above the platform and below the area targeted by the spray head reaches 25-30°C, which is equivalent to the temperature of the area being repaired on the photosensitive material board reaching 25-30°C.

[0027] Practice has proven that the photosensitive material plates obtained in this way will not exhibit deterioration or peeling of the photosensitive material coating at the repaired areas. This is because, generally, the production process of photosensitive material plates includes a fixing process with the photosensitive material solution, which is time-consuming. Since this is a repair, it needs to be completed quickly, and repeating the fixing process could damage other areas. In existing technologies, the temperature of the repair solution is often the same as the temperature of the repaired area, or the temperature is not limited, omitting the fixing process for the repaired area. This often results in photosensitive material plates where the repaired areas are prone to coating peeling and deterioration. This device, employing the above-mentioned solution, produces photosensitive material plates where the repaired areas are less prone to deterioration and peeling.

[0028] The first and second temperature regulating devices include heating devices and cooling devices. Any device that can change the temperature is a temperature regulating device. For example, the temperature regulating device can be an electric heating element or an air conditioner.

[0029] In one technical solution, the control device is a PLC control device, a microcontroller, or a control unit.

[0030] Furthermore, the device frame is also equipped with a refrigeration unit 7, which has a cold air outlet connected to a cold air output pipe 71. The cold air output pipe has a cold air release port 72. The refrigeration unit can make the air temperature flowing out of the cold air release port reach 5-10℃. The cold air release port is installed on the side of the spray head via a telescopic component 73. The telescopic component is connected to a control device, which can control the extension and retraction of the telescopic component. An electronic valve 74 is installed in the middle of the cold air output pipe. The electronic valve is connected to the control device, which can control the opening degree of the electronic valve. When the lifting device completes its lifting, the control device can cause the electronic valve to gradually open and the telescopic component to gradually extend; then the telescopic component is gradually retracted and the electronic valve is gradually closed.

[0031] By adopting the above-mentioned technical solution, the present invention can reduce cracks in the repair coating by blowing cold air onto the coating formed by the repair liquid after repairing the photosensitive material plate.

[0032] By adopting the above method, the repaired area can be clearly seen to be smooth and free of cracks when observed under a microscope, thus improving product quality.

[0033] The method for repairing defects in photosensitive material plates involves using a repair liquid to repair the defective areas. A spray nozzle is used to spray the repair liquid onto the defective area, and as spraying continues, the nozzle gradually moves away from the defective area (i.e., the area where the repair liquid is being sprayed). This process is called the repair liquid spraying process, and the amount of repair liquid sprayed from the nozzle gradually decreases during the spraying process.

[0034] Furthermore, during the repair process of the photosensitive material plate, the temperature of the defective part of the photosensitive material plate and its surrounding area is 25-30℃, the temperature of the repair liquid is 20-25℃, and the temperature of the repair liquid is 3-5℃ lower than the temperature of the defective part of the photosensitive material plate and its surrounding area.

[0035] After the repair liquid is applied, there is a process of blowing cold air onto the defective area. The temperature of the cold air blown onto the defective area is 5-10℃. As the cold air is blown, the air volume is gradually increased first and then gradually decreased to complete the repair of the defect on the photosensitive material board.

[0036] The above description is only a specific embodiment of the present invention, but the structural features protected by 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.
