Abstract
Description
Technical Field
[0001] This utility model relates to the field of blister product testing technology, and in particular to a defect detection device for blister products. Background Technology
[0002] Vacuum forming is a process where plastic sheets are heated and softened, then adhered to a mold surface using vacuum suction or other methods, and finally cooled and solidified to form various shapes. In practical applications, the inspection equipment typically requires the following technologies: 1. Image acquisition mechanism, responsible for acquiring image information of blister packaging products; 2. Lighting mechanism to provide sufficient and uniform light for testing; 3. Mechanical transmission mechanism, used for conveying thermoformed products; The camera begins to capture images, converting the optical images into digital signals, which are then transmitted to the image processing system for analysis. The image processing system processes and analyzes the captured images to determine whether there are any defects in the blister packaging. When a defect is detected, the alarm mechanism will issue an audible and visual alarm signal to remind the operator to take action.
[0003] Visual inspection equipment typically uses flat-panel cameras, which can only capture images of the top or front of the blister packaging. Due to blind spots in the shooting angle, some defects generated during processing on the sides may be missed, affecting product quality control. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a defect detection device for thermoformed products. It solves the technical problem that most visual inspection devices use planar cameras, which can only capture images of the top or front of the thermoformed product. For defects generated during processing on both sides, the blind spots in the shooting angle can lead to the omission of some defects, affecting the control of product quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A defect detection device for thermoformed products includes a detection platform, a support cantilever, a detection box, and a power box. Each power box has a sliding adjustment frame for horizontal sliding at its side end. Each sliding adjustment frame has a support plate for adjusting the angle. Each support plate has a coupling collar for imaging fixedly installed at its bottom end. Each support plate has a load-bearing docking pivot fixedly installed on its two inner sidewalls, which docks with the sliding adjustment frame. Each load-bearing docking pivot has an adjustment component on its surface. Each adjustment component includes a coupling collar and a positioning rod.
[0006] Preferably, each of the load-bearing docking pivots has a guide groove on its surface, and each of the coupling collars has a guide block fixedly installed on its inner sidewall; The power box contains a drive motor and a control circuit board, and a camera component is installed at the bottom of the power box. Each of the coupling collars has a slide block fixedly mounted on its surface that mates with the sliding adjustment frame, and each slide block has two multi-segment compression reset rods fixedly mounted on its side end.
[0007] Preferably, each of the two sides of the detection box is fixedly equipped with a guide slide plate, and each of the two sides of the detection box is rotatably equipped with a screw for driving the sliding adjustment frame to move, and the top of each screw is connected to a motor inside the power box; Each of the sliding adjustment brackets has a threaded connecting pipe fixedly installed on its inner side, which is connected to the lead screw.
[0008] Compared with the prior art, the present invention has the following beneficial effects; In this invention, by pulling the coupling collar, the coupling collar causes the guide block to slide on the surface of the load-bearing pivot. The guide block disengages from the inside of the guide groove. At the same time, the coupling collar causes the positioning rod to move at the side end of the sliding adjustment frame, releasing the fixed state of the support plate. This allows the support plate to deflect at the side end of the sliding adjustment frame, adjusting the shooting angle of the support plate. The thermoformed product can be photographed simultaneously from different angles, covering multiple surfaces such as its top and sides. This enables comprehensive inspection of the thermoformed product and improves the quality of the inspection.
[0009] In this invention, a rotating screw generates a thrust on the threaded connecting pipe, causing the sliding adjustment frame to slide at the side end of the detection box. Simultaneously, the sliding adjustment frame slides in conjunction with the guide slide plate. The guide slide plate guides and supports the movement of the sliding adjustment frame. The two sliding adjustment frames drive the support plate to adjust the spacing, allowing the position of the coupling ring to be adjusted for different sizes of blister products, facilitating image capture.

[0013] This application provides a defect detection device for blister products, effectively solving the problem that most visual inspection devices use planar cameras, which can only capture images of the top or front of the blister product. For defects generated during processing on both sides, blind spots in the shooting angle can lead to some defects being missed, affecting product quality control. By pulling the coupling ring, the guide block slides on the surface of the load-bearing pivot, disengaging from the guide groove. Simultaneously, the coupling ring moves the positioning rod at the side end of the sliding adjustment frame, releasing the fixed state of the support plate and allowing it to deflect at the side end of the sliding adjustment frame. This adjusts the shooting angle of the support plate, allowing simultaneous shooting of the blister product from different angles, covering multiple surfaces such as the top and sides, enabling comprehensive inspection of the blister product and improving inspection quality. Example
[0014] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that visual inspection equipment mostly uses planar cameras. Planar cameras can only capture images of the top or front of the blister product. For defects generated during processing on both sides, due to blind spots in the shooting angle, some defects will be missed, affecting the technical problem of product quality control. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a defect detection device for thermoformed products, including a detection platform 11, a support cantilever 12, a detection box 13, and a power box 14. Each power box 14 has a sliding adjustment frame 15 for horizontal sliding at its side end. Each sliding adjustment frame 15 has a support plate 19 for adjusting the angle. Each support plate 19 has a coupling collar 21 for imaging fixedly installed at its bottom end. Each support plate 19 has a load-bearing docking pivot 23 for docking with the sliding adjustment frame 15 fixedly installed on its two inner side walls. Each load-bearing docking pivot 23 has an adjustment component on its surface. Each adjustment component includes a coupling collar 21 and a positioning rod 22. Each load-bearing pivot 23 has a guide groove on its surface, and each coupling ring 21 has a guide block fixedly installed on its inner sidewall. By pulling the coupling ring 21, the coupling ring 21 drives the guide block to slide on the surface of the load-bearing pivot 23, and the guide block disengages from the inside of the guide groove. At the same time, the coupling ring 21 drives the positioning rod 22 to move at the side end of the sliding adjustment frame 15, releasing the fixed state of the support plate 19, allowing the support plate 19 to deflect at the side end of the sliding adjustment frame 15, adjusting the shooting angle of the support plate 19, and shooting the thermoformed product from different angles at the same time. This can cover multiple surfaces such as its top and sides, enabling all-round inspection of the thermoformed product and improving the quality of inspection.
[0015] The power box 14 contains a drive motor and a control circuit board. The bottom of the power box 14 is equipped with a camera component to process and analyze the acquired images, identify the type, location and size of defects in the thermoformed product, and compare them with a preset standard image to determine whether the product is qualified. Each coupling collar 21 has a slide block 24 fixedly installed on its surface to mate with the sliding adjustment frame 15. Each slide block 24 has two multi-segment compression reset rods 25 fixedly installed on its side end. The reverse pulling force applied to the slide block 24 by the reset rods 25 causes the slide block 24 to slide toward the side end of the sliding adjustment frame 15, while driving the coupling collar 21 to slide on the surface of the load-bearing docking pivot 23, so that the coupling collar 21 can quickly lock the angle of the support plate 19. Each detection box 13 has a guide slide plate 18 fixedly installed on both sides, and each detection box 13 has a screw 17 rotatably installed on both sides to drive the sliding adjustment frame 15 to move. The top of each screw 17 is connected to the motor inside the power box 14. Through the meshing of the transmission rod and the gear, the two screws 17 are driven to rotate on the side of the detection box 13. Each sliding adjustment bracket 15 has a threaded connecting pipe 16 fixedly installed on its inner side, which is connected to the screw 17. The lower half of the screw 17 engages with the threaded connecting pipe 16, and the rotating screw 17 generates a thrust on the threaded connecting pipe 16, allowing the sliding adjustment bracket 15 to slide at the side end of the detection box 13. At the same time, the sliding adjustment bracket 15 slides with the guide slide plate 18. The guide slide plate 18 guides and supports the movement of the sliding adjustment bracket 15. The two sliding adjustment brackets 15 drive the support plate 19 to adjust the spacing, which can adjust the position of the coupling ring 21 for different sizes of blister products, making it easier to capture images.
[0016] Working principle: The first step involves the coupling ring 21 and the camera component at the bottom of the power box 14 acquiring image information of the thermoformed product, converting the optical image into a digital signal, and transmitting it to the image processing system for analysis and processing. The power box 14 contains a drive motor and a control circuit board. The bottom of the power box 14 is equipped with a camera component that processes and analyzes the acquired images, identifies the type, location, and size of defects in the thermoformed product, and compares them with a preset standard image to determine whether the product is qualified.
[0017] The second step involves pulling the coupling collar 21, causing it to slide the guide block on the surface of the bearing pivot 23. The guide block disengages from the guide groove, and simultaneously, the coupling collar 21 moves the positioning rod 22 to the side end of the sliding adjustment frame 15, releasing the fixed state of the support plate 19. This allows the support plate 19 to deflect at the side end of the sliding adjustment frame 15, adjusting the shooting angle of the support plate 19. Simultaneous shooting of the blister product from different angles can cover multiple surfaces, including the top and sides, enabling comprehensive inspection and improving inspection quality. The reverse pulling force applied to the slide 24 by the reset rod 25 then allows the slide 24 to... The sliding adjustment frame 15 slides to the side end, simultaneously causing the coupling collar 21 to slide on the surface of the bearing docking pivot 23, allowing the coupling collar 21 to quickly lock the angle of the support plate 19. The rotating screw 17 generates a thrust on the threaded connecting pipe 16, causing the sliding adjustment frame 15 to slide at the side end of the detection box 13. At the same time, the sliding adjustment frame 15 slides and docks with the guide slide plate 18. The guide slide plate 18 guides and supports the movement of the sliding adjustment frame 15. The two sliding adjustment frames 15 drive the support plate 19 to adjust the spacing, which can adjust the position of the coupling collar 21 for different sizes of blister products, making it convenient to take pictures.
[0018] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
