Description

Technical Field

[0001] This utility model relates to the field of online inspection equipment technology, specifically to an online defect inspection device for the production of vapor phase rust-preventing paper. Background Technology

[0002] Vapor phase corrosion inhibitor (VCI) paper is a special rust-preventive packaging material made from special neutral paper as the base material, coated with special substances of different formulations as vapor phase corrosion inhibitors, and processed through a series of post-processing steps. In a relatively sealed packaging space, the VCI in the VCI paper sublimates and volatilizes at room temperature and pressure, releasing rust-preventive gaseous factors. These factors diffuse and penetrate to the surface of the item being protected and adsorb onto it, forming a dense protective film layer one molecule thick, thus achieving the purpose of rust prevention. This protective film effectively prevents corrosion of metals by atmospheric elements such as oxygen and moisture, achieving long-term, stable, and excellent rust prevention in a sealed space. Therefore, a surface defect detection device is needed for quality inspection during the production and processing of this type of vapor phase corrosion inhibitor paper.

[0003] Existing online defect detection equipment for paper production lacks a structure for guiding paper feeding during use. For example, a paper surface defect detection device disclosed in application number CN202021539207.3. Existing detection devices lack a structure for guiding paper feeding after detection. While the detection device operates continuously at high speed, the feeding process lacks automated guidance. Paper accumulation or jamming increases manual workload, requiring operators to continuously guide the feeding process, increasing processing complexity. The separation of detection and feeding processes necessitates additional manual or equipment coordination, increasing automation costs. The lack of a guiding feeding structure means that an automated process from detection to feeding cannot be achieved, increasing labor costs and reducing production efficiency. Manual feeding operations may introduce uncertainties; improper manual operation can lead to paper jamming, increasing the risk of equipment failure. Furthermore, the lack of a guiding feeding structure prevents seamless integration of the detection device with other automated equipment, limiting the automation efficiency of the production line.

[0004] Therefore, it is necessary to invent an online defect detection device for the production of vapor phase rust-preventing paper to solve the above problems. Utility Model Content

The two detection devices 5 are set diagonally. The detection device 5 includes a detection frame 501 and a detection camera 502. The detection frame 501 is located on both sides of the outer wall of the conveyor frame 2. The detection camera 502 is installed below the front end of the detection frame 501. The detection camera 502 is located directly above the conveyor belt 3. A protective plate 6 is installed on the top surface of the conveyor frame 2. Two protective plates 6 are installed, which are located on the two sides of the surface of the conveyor frame 2 respectively. The protective plates 6 are located on both sides of the anti-rust paper body 4.

[0024] A feeding device 7 is provided at one end of the conveying device 1, and the feeding device 7 is located at the feeding end of the conveying frame 2. The feeding device 7 includes a fixed seat 701 and a transition plate 702. The fixed seats 701 are respectively fixedly installed on both sides of the tail end surface of the conveying frame 2. A transition plate 702 is provided between the ends of the two fixed seats 701. The fixed seats 701 are respectively located on both sides of the anti-rust paper body 4 at the lower end of the conveyor belt 3. There is a distance between the inner bottom surface of the fixed seat 701 and the anti-rust paper body 4. The connection part between the transition plate 702 and the fixed seat 701 is semi-cylindrical. The lower two sides of the transition plate 702 are raised. The width of the transition plate 702 is greater than the width of the anti-rust paper body 4. The lower end of the transition plate 702 is inclined.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-5 Using this online defect detection equipment for the production of weather-resistant rust-proof paper, the conveying device 1 consists of a conveyor frame 2 and a conveyor belt 3. The conveyor belt 3 is located in the middle of the conveyor frame 2 and is used to continuously transport the rust-proof paper body 4. Silicone pads 301 are set on both sides of the surface of the conveyor belt 3. When the rust-proof paper body 4 is placed on the conveyor belt 3, its bottom sides are attached to the silicone pads 301. The silicone material also has good elasticity and friction, and is chemically stable, so it is not easy to react chemically with the rust-proof paper, ensuring that the rust-proof paper remains stable during the conveying process and preventing deviation or slippage. The detection device 5 includes a detection frame 501 and a detection camera 502. The detection frame 501 is located on both sides of the outer wall of the conveyor frame 2. The detection camera 502 is installed below the front end of the detection frame 501 and directly above the conveyor belt 3. The two detection devices 5 are set diagonally, which can perform comprehensive detection on both sides of the rust-proof paper body 4. The detection camera 502 adopts a high-resolution industrial camera and captures images of the rust-proof paper surface in real time through a high-speed image acquisition and processing system. When defects appear on the surface of the rust-proof paper, the image features of the defective area are significantly different from those of the normal area. The system identifies these defects through image analysis algorithms and records their locations. The feeding device 7 includes a fixed seat 701 and a transition plate 702. The fixed seats 701 are fixedly installed on both sides of the tail end surface of the conveyor frame 2. The transition plate 702 is provided between the ends of the two fixed seats 701. The fixed seats 701 are located on both sides of the rust-proof paper body 4 at the feeding end of the conveyor belt 3. The inner bottom surface of the fixed seat 701 is flush with the rust-proof paper body. There is a distance between 4 to avoid obstructing the conveying of the rust-proof paper. The connection between the transition plate 702 and the fixed base 701 is semi-cylindrical. The lower two sides of the transition plate 702 are raised. The width of the transition plate 702 is greater than the width of the rust-proof paper body 4. The lower end of the transition plate 702 is inclined. When the rust-proof paper body 4 is conveyed to the feeding end, the rust-proof paper is smoothly guided by the inclination of the transition plate 702 to the next process or collection device, avoiding jamming or damage to the rust-proof paper during the feeding process.

[0027] When using this device, install the conveyor frame 2 on the production line, adjust the tension of the conveyor belt 3 to ensure smooth conveying, install the detection device 5, and adjust the height and angle of the detection camera 502 to clearly capture the surface image of the rust-proof paper body 4. Install the unloading device 7, and adjust the position and angle of the transition plate 702 to ensure smooth unloading of the rust-proof paper. Start the conveyor device 1, and the conveyor belt 3 begins to operate. Place the rust-proof paper body 4 on the conveyor belt 3, with both sides of the bottom surface of the rust-proof paper body 4 attached to the silicone pads 301. Convey it forward with the conveyor belt 3. The detection device 5 starts working, and the detection camera 502 acquires the surface image of the rust-proof paper body 4 in real time and processes it through the image processing system. The system analyzes and identifies defects. When a defect is detected on the surface of the rust-proof paper body 4, the system records the defect information and alerts the operator through an audible and visual alarm. The operator can mark or remove the defective rust-proof paper according to the defect information to ensure that unqualified products do not flow into the next process. When the rust-proof paper body 4 is conveyed to the unloading end, it slides smoothly into the collection device of the next process through the transition plate 702. After the equipment is used, the conveyor belt 3 and the detection camera 502 are cleaned regularly to prevent dust or stains from affecting the detection accuracy. The wear of the silicone pad 301 is checked and replaced in time if it is damaged. The image processing system of the detection device 5 is calibrated to ensure the accuracy of the detection results.
