Description

Technical Field

[0001] This utility model relates to the field of PS plate substrates, specifically a high-precision online detection device for surface defects of PS plate substrates. Background Technology

[0002] PS plate base is the basic carrier of pre-coated photosensitive plate. It is mainly made of aluminum alloy thin plate through a series of precision processing. Its surface needs to undergo special treatments such as sanding, anodizing, and sealing to form a uniform oxide film layer with a certain roughness. This oxide film can not only enhance the adhesion of the photosensitive layer, but also improve the printing durability of the plate.

[0003] However, when performing defect detection on the surface of PS substrates, it is difficult to clean and pre-treat the PS substrates. Dust and water stains covering the surface of the PS substrates will interfere with the imaging effect, leading to misjudgment of defects and reducing the detection accuracy and reliability. To address this issue, we propose a high-precision online defect detection device for PS substrates to solve the above problems. Utility Model Content

[0016] According to one embodiment of the present invention, in conjunction with the appended drawings Figure 1-4 As shown.

[0017] A high-precision online inspection device for surface defects on PS substrates includes a conveying mechanism 1, a housing 2 above the conveying mechanism 1, a high-precision industrial camera 3 fixedly mounted on the inner top wall of the housing 2, a high-pressure blower 4 mounted on the back of the housing 2, a connecting pipe 5 fixedly connected to the outlet end of the high-pressure blower 4, the end of the connecting pipe 5 away from the high-pressure blower 4 penetrating the housing 2 and extending into the interior of the housing 2, and a spray pipe 6 fixedly connected to the end of the connecting pipe 5 away from the high-pressure blower 4, a spray hood 7 fixedly connected to the outer surface of the spray pipe 6, and an installation port 8 on the upper surface of the housing 2. Two mounting plates 9 are fixedly installed on the inner wall of the mounting port 8. An electric push rod 10 is mounted on one side of the two mounting plates 9 that are close to each other. A bracket 11 is fixedly installed on the telescopic end of the electric push rod 10. Two first bearings 12 are fixedly embedded in the inner wall of the bracket 11. Rotating rods 13 are fixedly connected to the inner rings of the two first bearings 12. A cleaning roller 14 is fixedly installed on one side of the two rotating rods 13 that are close to each other. A mounting cover 15 is fixedly connected to the upper surface of the housing 2. A blower 16 is fixedly installed on the inner wall of the mounting cover 15. The housing 2 is equipped with a fixed electric heating wire 17 and two lighting lamps 21 fixedly installed on the inner top wall. Through the arrangement of a high-pressure blower 4, a connecting pipe 5, a spray pipe 6, and a spray hood 7, air can be blown and conveyed to perform preliminary air cleaning of the PS substrate surface, removing most of the surface dust. An electric push rod 10 pushes the support 11 downwards, allowing the cleaning roller 14 to contact the PS substrate surface for further wiping and cleaning of water stains. The blower 16 and electric heating wire 17 can blow and heat simultaneously, generating hot air to dry the PS substrate surface, removing any remaining water stains and preventing moisture residue from affecting imaging. This reduces interference from dust and water stains on the detection process, solving the problem that dust and water stains on the PS substrate surface interfere with imaging, reducing false defect judgments, and improving detection accuracy and reliability. Furthermore, the cooperation of the conveying mechanism 1, the high-precision industrial camera 3, and the two lighting lamps 21 enables automatic conveying of the PS substrate and simultaneous high-precision online surface defect detection, improving the detection efficiency of the PS substrate.

[0018] In this embodiment, the conveying mechanism 1 includes two carrier plates 101. The upper surfaces of the two carrier plates 101 are fixedly installed to the bottom surface of the housing 2. A servo motor 102 is installed on the back of one carrier plate 101. Two second bearings 103 are fixedly embedded on the side of the two carrier plates 101 that are close to each other. The inner rings of the two sets of second bearings 103 are fixedly connected to two rotating rods 104. The outer surfaces of the two rotating rods 104 are connected to a conveyor belt 105. The surface of the conveyor belt 105 is provided with anti-slip texture. The rear end of one rotating rod 104 is fixedly installed to the output end of the servo motor 102. By using the conveying mechanism 1, the servo motor 102 can be started to work, which can drive the two rotating rods 104 and the conveyor belt 105 to rotate, and can automatically convey the PS plate base to the inside of the housing 2 for preprocessing and defect detection.

[0019] In this embodiment, two stabilizing plates 18 are fixedly installed on the inner top wall of the housing 2. The bottom surfaces of the two stabilizing plates 18 are fixedly installed on the outer surface of the air spray pipe 6. A PLC controller 19 is fixedly installed on the front of the housing 2. A protective net 20 is fixedly connected to the inner wall of the mounting cover 15. Two connecting plates 22 are fixedly installed on the inner wall of the housing 2. Limiting plates 23 are fixedly installed on the side of the two connecting plates 22 that are close to each other. Three sets of third bearings 24 are fixedly embedded on the side of the two carrier plates 101 that are close to each other. Three rotating rods 25 are fixedly connected to the inner ring of the three sets of third bearings 24. The outer surfaces of the three rotating rods 25 are in contact with the inner ring of the conveyor belt 105. The two stabilizing plates 18 can make the air spray pipe 6 more stable. The PLC controller 19 can control the equipment. The protective net 20 can block dust and impurities. The two connecting plates 22 and the two limiting plates 23 can limit the PS plate base and ensure accurate detection position. The three sets of third bearings 24 and the three rotating rods 25 can form bottom support for the conveyor belt 105 and ensure smooth conveying.

[0020] Working principle: First, the PS substrate is placed on the conveyor belt 105, and the conveyor mechanism 1 is started to automatically transport the PS substrate into the housing 2. After the PS substrate enters the housing 2, the high-pressure blower 4 is started to blow air through the pipe 5 to the air spray pipe 6, and then sprayed out through the air spray hood 7 to perform preliminary air blowing and cleaning of the surface of the PS substrate, removing most of the surface dust. Then, the electric push rod 10 is started to push the bracket 11 to move down, so that the cleaning roller 14 contacts the surface of the PS substrate. During the movement of the PS substrate, the cleaning roller 14 is moved by three rotating rods 13. The first bearing 12 rotates to further wipe and clean the surface of the PS substrate. After cleaning, the PS substrate continues to move, and the blower 16 is activated to generate airflow. After being heated by the electric heating wire 17, hot air is generated to dry the surface of the PS substrate and remove any water stains. Then, two lights 21 are turned on to provide sufficient illumination. The high-precision industrial camera 3 images the cleaned and dried surface of the PS substrate and transmits the images to the PLC controller 19 for analysis and identification. The images are processed according to preset parameters to determine whether there are scratches, dents, or other defects.

[0021] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
