Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and more particularly to a packaging foam detection device with a rapid positioning function. Background Art

[0002] Packaging foam inspection devices are specialized equipment used to test the physical, chemical, and appearance quality of packaging foams (such as polystyrene foam and EPE foam). They are widely used in packaging material production, quality inspection, and scientific research. Their primary function is to ensure that packaging foams comply with relevant standards and usage requirements, guaranteeing product safety and stability during transportation and storage. One of the inspection methods involves visual inspection of packaging foams to identify surface or internal defects. Using cameras and image processing technology, these devices can detect surface defects such as bubbles, cracks, missing material, and flash. They can also measure the size and shape of the foam to ensure it meets design requirements.

[0003] On this basis, after searching the patent website, Chinese patent application No. 202010439409.9 provides a packaging foam detection device, which places the packaging foam vertically, with the bottom part placed on a placement plate, clamped by a clamping plate, and the placement plate can be raised and lowered to accommodate packaging foams of different specifications. The head of the packaging foam is hooked by a draw hook, and then the draw hook applies a certain pulling force through a pulling motor to pull up and observe whether the foam is damaged, thereby performing a pulling strength test. A pressure sensor is set on the inner side of the clamping plate to detect the pressure; It can be seen that the above patent application has the following shortcomings: although the traditional packaging foam detection device can detect whether the packaging foam is qualified when in use, the device lacks the function of sorting the packaging foam. The device is not convenient for automatically classifying and collecting qualified and unqualified packaging foams, which makes it inconvenient for the operator to handle unqualified packaging foam, reducing the working efficiency of the device.

[0021] By adopting the above mechanism, the controller and the detection camera cooperate to analyze whether the appearance of the packaging foam is qualified.

[0022] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. When it is necessary to inspect the packaging foam to be inspected, the packaging foam to be inspected can be placed under the inspection camera body 23, and the inspection camera body 23 is turned on in working mode. At the same time, the two sets of lighting lamps 24 are turned on in lighting mode. The inspection camera body 23 is responsible for capturing the image of the packaging foam, and the lighting lamps 24 provide sufficient and uniform lighting for shooting to ensure the clarity and quality of the image. The captured image is converted into an image signal and the signal is sent to the intelligent controller 4. The intelligent controller 4 has powerful computing power and can quickly process and analyze the collected image data, execute algorithms such as feature extraction, recognition, and measurement, and quickly determine the location of the appearance defects of the packaging foam based on the results of the image processing system; 2. When using the device, place the packaging foam to be tested on the top surface of the feeding end of the second conveyor belt 14, start the transport mode of the second conveyor belt 14, and the second conveyor belt 14 transports the packaging foam to be tested to the bottom of the detection camera body 23. Then, the transport work of the second conveyor belt 14 is turned off. In order to prevent the packaging foam from shifting during the inspection process, the user starts the working mode of the first motor 291. The first motor 291 drives the first forward and reverse screw 29 to rotate forward, and then the first forward and reverse screw 29 drives the two sets of support plates 27 to move closer to each other. The support plates 27 move horizontally along the limit groove 25 track, and then the support plates 27 drive the clamping blocks 26 to move closer to the packaging foam until the two sets of clamping blocks 26 are clamped and limited on both sides of the packaging foam. After the positioning, the packaging foam will be more stable when the quality is inspected by the detection camera body 23. This setting uses the positioning mechanism to limit the packaging foam during the inspection process, which can prevent the packaging foam from shifting during the inspection process, and better utilize the device to inspect the items during the stable process, thereby improving the inspection accuracy of the device. 3. After the device uses the detection camera body 23 to detect the packaging foam, it starts the first motor 291. The first motor 291 drives the first forward and reverse screw 29 to rotate in the opposite direction. The first forward and reverse screw 29 will drive the clamping block 26 to move horizontally toward the inside of the cavity box 21, and then the two groups of clamping blocks 26 will move in the direction away from the packaging foam until the clamping blocks 26 are retracted into the inside of the cavity box 21. At this time, the clamping blocks 26 give up the clamping work of the packaging foam and continue to use the transmission mode of the second conveyor belt 14 to transport the packaging foam forward. When the intelligent controller 4 analyzes that the packaging foam is unqualified, the intelligent controller 4 will send a signal to the second motor 36 and turn it on. The second motor 36 drives the second forward and reverse screw 38 to rotate forward, and then the two groups of limit blocks 352 and the two sets of lower sliders 351 move towards each other, and the push block 32 is used to push the unqualified items on the second conveyor belt 14 to the top surface of the first conveyor belt 13. At the same time, the transmission mode of the first conveyor belt 13 is turned on, and the unqualified packaging foam is transferred by the first conveyor belt 13 and collected by the collecting box 5 on the front side of the first conveyor belt 13, while the qualified packaging foam will continue to be smoothly transported by the second conveyor belt 14 and collected by the collecting box 5 at the front end of the second conveyor belt 14. Such operation will facilitate subsequent workers to uniformly handle unqualified packaging foam, and can assist the device in collecting qualified and unqualified inspection items separately. The operation is simple and quick, avoids manual distinction, and improves the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] To sum up, the working principle is as follows: visual inspection technology is a mature existing technology on the market. It can detect bubbles, cracks, impurities, color unevenness and other defects on the foam surface through high-definition cameras and image processing algorithms. Visual inspection technology usually uses industrial cameras to take high-speed real-time photos of the object to be tested and transmits them to the image processing control system to determine whether the appearance quality of the packaging foam is qualified; The detection camera body 23 in the device of the present application adopts the BNC-302 model visual inspection camera on the market. When the packaging foam to be tested needs to be tested, the packaging foam to be tested can be placed under the detection camera body 23, the detection camera body 23 working mode is turned on, and the two sets of lighting lights 24 lighting modes are turned on at the same time. The detection camera body 23 is responsible for capturing the image of the packaging foam, and the lighting lights 24 provide sufficient and uniform lighting for shooting to ensure the clarity and quality of the image, convert the captured image into an image signal, and send the signal to the intelligent controller 4. The intelligent controller 4 adopts the LH-D6901 model multi-function controller, which has powerful computing power, can quickly process and analyze the collected image data, execute feature extraction, recognition, measurement and other algorithms, and can quickly determine the location of the appearance defects of the packaging foam according to the results of the image processing system; When using the device, the packaging foam to be tested is placed on the top surface of the feeding end of the second conveyor belt 14, the transportation mode of the second conveyor belt 14 is turned on, the second conveyor belt 14 transports the packaging foam to be tested to the bottom of the detection camera body 23, and the transportation work of the second conveyor belt 14 is turned off. In order to prevent the packaging foam from deviating during the inspection process, the user turns on the working mode of the first motor 291, and the first motor 291 drives the first forward and reverse screw 29 to rotate forward, and then the first forward and reverse screw 29 drives the two sets of support plates 27 to move closer to each other, and the support plates 27 move horizontally along the limit groove 25 track, and then the support plates 27 drive the clamping blocks 26 to move closer to the packaging foam until the two sets of clamping blocks 26 are clamped and limited on both sides of the packaging foam. The packaging foam after being limited will be more stable when the quality is inspected by the detection camera body 23; this setting limits the packaging foam during the inspection process through the positioning mechanism, which can prevent the packaging foam from deviating during the inspection process, and better utilize the device to inspect the items during the stable process, thereby improving the inspection accuracy of the device; After the device uses the detection camera body 23 to detect the packaging foam, the first motor 291 is started. The first motor 291 drives the first forward and reverse screw 29 to rotate in the opposite direction. The first forward and reverse screw 29 will drive the clamping block 26 to move horizontally toward the inside of the cavity box 21, and then the two groups of clamping blocks 26 will move in the direction away from the packaging foam until the clamping blocks 26 are both retracted into the inside of the cavity box 21. At this time, the clamping blocks 26 give up the clamping work on the packaging foam and continue to use the transmission mode of the second conveyor belt 14 to transport the packaging foam forward. When the intelligent controller 4 analyzes unqualified packaging foam, the intelligent controller 4 will send a signal to the second motor 36 and start its working mode. The second motor 36 drives the second forward and reverse screw 38 to rotate forward, and then the two groups of limit blocks 352 and the two groups of lower sliders 351 move closer to each other. At the same time, the two groups of rotating rod components 361 rotate, and the two groups of upper sliders 341 move relative The second motor 36 then drives the second forward and reverse screw 38 to move in the opposite direction, and the second forward and reverse screw 38 drives the two sets of lower sliders 351 to move away from each other, and then the two sets of upper sliders 341 to move away from each other. At the same time, the two sets of rotating rod components 361 drive the sliding plate 34 to move in the direction close to the support block 35, and then the pushing block 32 moves again in the direction close to the protective box 31 until the pushing block 32 returns to its original position. At the same time, the transmission mode of the first conveyor belt 13 is turned on, and the unqualified packaging foam is transferred by the first conveyor belt 13 and collected by the collecting box 5 on the front side of the first conveyor belt 13. The qualified packaging foam will continue to be transported smoothly through the transmission of the second conveyor belt 14, and will be collected by the collection box 5 at the front end of the second conveyor belt 14. This operation will facilitate the subsequent workers to carry out unified processing of unqualified packaging foam, and can assist the device to collect qualified and unqualified inspection items separately.
