Description

Technical Field

[0001] This utility model relates to the field of die-cut product inspection technology, specifically to an AOI intelligent inspection machine for die-cut products. Background Technology

[0002] After mass production, rolls / sheets such as die-cut parts, printed materials, etched products and semiconductor sheets need to be 100% inspected for appearance defects such as dimensional accuracy, hole positions, foreign objects, scratches, and waste discharge. Traditional inspection methods mainly rely on manual visual inspection or offline sampling inspection.

[0003] Manual visual inspection is slow, and the inspection time for a single item increases exponentially with the complexity of the defect; the inspection process requires frequent shutdowns for image adjustment and material change, which disrupts the production line cycle and reduces overall efficiency; operators are prone to visual fatigue from staring at high-brightness light sources for long periods of time, and the misjudgment rate increases exponentially with the working time; in order to alleviate manpower pressure, some companies adopt a sampling inspection model, but the sampling ratio is low and the coverage is incomplete, which significantly increases the risk of missed inspections.

[0004] To address this, an AOI intelligent inspection machine for die-cut products was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an AOI intelligent inspection machine for die-cut products in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An AOI intelligent inspection machine for die-cut products includes a frame on which an industrial inspection mechanism is installed for batch and continuous inspection of die-cut products passing through the industrial inspection mechanism. An inspection terminal is installed on the frame, and a main material pulling assembly is fixedly installed on the top surface of the frame.

[0008] Furthermore, the frame is provided with a product position and a receiving position on both sides for continuous conveying of die-cut products.

[0009] Furthermore, the industrial testing mechanism includes a housing fixedly mounted on a frame, and a first mounting bracket and a second mounting bracket are fixedly mounted on the inner walls of both sides of the frame and the housing, respectively, and are staggered and corresponding. An industrial camera is fixedly mounted on the first mounting bracket, and a backlight is fixedly mounted on the second mounting bracket.

[0010] Furthermore, the industrial camera and the backlight are arranged in a corresponding manner and are located on the upper and lower sides of the die-cut product, and the industrial camera is connected to the detection system built into the detection terminal.

[0011] Furthermore, the main material pulling assembly includes two sets of side frames fixedly installed on the top surface of the frame. A motor is fixedly installed on the surface of the side frame, and a material pulling roller is fixedly connected to the output end of the motor. A slider is slidably installed inside the side frame, and a pressure roller is rotatably inserted on the two sets of sliders. The material pulling roller and the pressure roller are arranged vertically correspondingly. The pressure roller, through its own weight and the weight of the two sets of sliders, vertically presses the die-cut product against the material pulling roller.

[0012] Furthermore, the frame is equipped with a manual inspection area, which is used to manually inspect die-cut products by turning on the light source in the manual inspection area.

[0013] The beneficial effects of this utility model are as follows:

[0014] The industrial testing facility forms a continuous testing channel within itself, and the main material pulling component provides constant traction, allowing die-cut products to pass through the testing channel sequentially. This enables batch testing without stopping the machine, improving testing efficiency. The testing terminal receives image data in real time and completes defect judgment, forming a closed-loop testing process. Attached Figure Description

[0025] like Figures 1 to 5 As shown, the die-cut product AOI intelligent inspection machine includes a frame 1, on which an industrial inspection mechanism 4 is installed for batch and continuous inspection of die-cut products passing through the industrial inspection mechanism 4. An inspection terminal 6 is also installed on the frame 1. Figure 3 and Figure 5 As shown, specifically, the industrial testing mechanism 4 includes a housing 401 fixedly installed on the frame 1, and a first mounting bracket 402 and a second mounting bracket 404 are fixedly installed on the inner walls of both sides of the frame 1 and the housing 401, respectively, and are staggered and corresponding. An industrial camera 403 is fixedly installed on the first mounting bracket 402, and a backlight 405 is fixedly installed on the second mounting bracket 404.

[0026] More specifically, the staggered arrangement of the first mounting bracket 402 and the second mounting bracket 404 enables the industrial camera 403 and the backlight 405 to form an upward and downward opposing light path. The backlight 405 provides uniform backlighting, and the industrial camera 403 acquires high-contrast images, enabling simultaneous inspection of the front and back sides of the die-cut product and improving the accuracy of the inspection.

[0027] like Figure 3 and Figure 5As shown, in some practical applications, the industrial camera 403 and the backlight 405 are arranged in a corresponding manner and are located on the upper and lower sides of the die-cut product, and the industrial camera 403 is connected to the detection system built into the detection terminal 6.

[0028] More specifically, the vertically positioned industrial camera 403 and backlight 405 capture images of the product outline and defects in real time. The image signals are directly sent to the inspection terminal 6 via hardwire or high-speed interface for algorithm analysis to complete defect identification and classification, ensuring inspection accuracy and speed.

[0029] The main material pulling assembly 7 is fixedly installed on the top surface of the frame 1; such as Figures 1 to 4 As shown, specifically, the main feeding assembly 7 includes two sets of side frames 701 fixedly installed on the top surface of the frame 1. A motor 702 is fixedly installed on the surface of the side frame 701, and a feeding roller 703 is fixedly connected to the output end of the motor 702. A slider 704 is slidably installed inside the side frame 701. A pressure roller 705 is rotatably inserted on the two sets of sliders 704. The feeding roller 703 and the pressure roller 705 are vertically corresponding. The pressure roller 705 vertically presses the die-cut product with the feeding roller 703 by its own weight and the weight of the two sets of sliders 704.

[0030] More specifically, the pull roller 703 is driven by the motor 702 to rotate at a constant speed, and the pressure roller 705, relying on its own weight and the gravity and guidance of the slider 704, is always elastically pressed with the pull roller 703 to form a clamping force, ensuring that the die-cut product moves forward continuously without slippage or wrinkles during the inspection process.

[0031] like Figures 1 to 3 As shown, in some practical applications, the frame 1 is provided with product position 2 and receiving position 3 on both sides for continuous conveying of die-cut products.

[0032] More specifically, product position 2 serves as the upstream feeding end, and receiving position 3 serves as the downstream receiving end. Together with the main feeding assembly 7, they form a straight conveying path to ensure that the die-cut products enter and leave the inspection area at a constant speed and with a stable posture.

[0033] like Figures 1 to 3 As shown, in some practical applications, a manual inspection area 5 is embedded on the frame 1, which is used to manually inspect the die-cut products by turning on the light source in the manual inspection area 5.

[0034] More specifically, when the detection terminal 6 determines a suspected defect, the operator can use the built-in light source in the manual review area 5 to provide sufficient illumination for manual review, thus avoiding false rejection or missed detection.

[0035] In summary: The industrial inspection mechanism 4 forms a continuous inspection channel within it, and the main material pulling component 7 provides a constant traction force, allowing the die-cut products to pass through the inspection channel sequentially, achieving batch inspection without stopping the machine and improving inspection efficiency. The inspection terminal 6 receives image data in real time and completes defect judgment, forming a closed-loop inspection process.
