Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic detection machines and defective product separation thereof, and particularly relates to an automatic detection machine and a defective product separation structure thereof. Background Art
[0002] In modern manufacturing, strict control of product quality is the cornerstone of a company's survival and growth. With the continuous advancement of production technology and increasing automation, higher requirements have been placed on the inspection and classification of product appearance quality. In traditional production processes, product appearance inspection has largely relied on manual labor. Workers must maintain their concentration for extended periods, inspecting each product individually. This is not only labor-intensive and inefficient, but also prone to misjudgments and omissions due to factors such as human subjectivity and fatigue. This approach clearly cannot adapt to the needs of large-scale, high-efficiency modern production. To improve inspection efficiency and accuracy, automated appearance inspection equipment has gradually been introduced into the production process. However, after inspection, how to quickly, accurately, and non-destructively separate good from defective products has become a pressing issue.
[0003] Common defective product separation devices in the past have many shortcomings. Some devices have a relatively simple structural design, relying solely on a single baffle or slide to separate good and defective products, lacking flexibility and adaptability. For some products with fragile and easily damaged surfaces, on high-speed production lines, the items move at a high speed. When they come into contact with the separation components, due to the lack of an effective buffering mechanism, they will produce a strong impact, which may not only damage the products and affect product quality, but also cause increased wear and tear on the equipment and shorten its service life. Moreover, due to the long-term exposure to large impact forces, the components of these separation devices are prone to deformation and damage, increasing maintenance costs and downtime, causing considerable economic losses to the company.
[0004] To this end, we proposed an automatic inspection machine and its defective product separation structure. By setting up good product areas and defective product areas and guiding them through the rotation of the guide plate, the device can accurately guide good and defective products to different areas, thereby improving the accuracy and efficiency of sorting. At the same time, when an item hits the guide plate, the guide plate squeezes the spring through the arc rod. The elastic force of the spring can reduce the impact force and slow down the movement speed of the item, thereby effectively preventing the item from being damaged by rapid movement and impact, and protecting the item. Utility Model Content
[0005] The purpose of this utility model is to provide an automatic inspection machine and a defective product separation structure thereof. The device can accurately guide good products and defective products to different areas, thereby improving the accuracy and efficiency of sorting. At the same time, when the items hit the guide plate, the movement speed of the items is slowed down, thereby effectively preventing the items from being damaged due to rapid movement and impact, and playing a protective role for the items.
[0006] The technical solutions adopted in this application are as follows:
[0007] A defective product separation structure includes a first bracket and a second bracket, wherein the first bracket is provided with a conveyor belt, the second bracket is provided with a blanking plate in contact with the conveyor belt, a partition plate is provided at the center of the blanking plate, the partition plate divides the blanking plate into a good product area and a defective product area, and the partition plate is provided with a material guide assembly;
[0008] The material guide assembly includes two fixed blocks arranged on the partition plate, the two fixed blocks are provided with a rotating assembly, the rotating assembly is provided with a connecting rod, one end of the connecting rod is provided with a material guide plate, and an elastic assembly is provided between the material guide plate and the partition plate;
[0009] The elastic component includes an arc-shaped shell connected to the partition plate and an arc-shaped rod connected to the material guide plate. A spring is provided inside the arc-shaped shell, and one side of the spring is connected to the arc-shaped rod located inside the arc-shaped shell.
[0010] Furthermore, the conveyor belt and the blanking plate are both provided with protective plates.
[0011] Furthermore, the rotating assembly includes a rotating shaft rotatably arranged between the two fixed blocks, a motor connected to one of the fixed blocks is arranged on the rotating shaft, and the outer side of the rotating shaft is connected to the connecting rod.
[0012] Furthermore, a first smooth surface is provided on the material guide plate, and a second smooth surface is provided inside the good product area and the defective product area.
[0013] Furthermore, the center of the arc rod is the same as the center of the rotating shaft.
[0014] Furthermore, a buffer layer is provided on the guide plate.
[0015] An automatic detection machine comprises a third bracket, a support plate is arranged on the top of the third bracket, and a detector is arranged on the bottom of the support plate.
[0016] The technical effects achieved by this utility model are:
[0017] First, place the object on the conveyor belt, and after detection, determine whether the object is good or defective. If it is a good product, the rotating component rotates at this time, and the rotating component drives the connecting rod to rotate the guide plate to a certain angle. When the guide plate rotates, it drives the arc rod to move inside the arc shell, thereby squeezing the spring, so that the spring has elasticity, and then the defective area is sealed. At this time, the guide plate and the good area form a good material guide channel. At the same time, the conveyor belt drives the object to collide with the guide plate first. This impact force will again cause the guide plate to drive the arc rod to move inside the arc shell to squeeze the spring. The elastic force of the spring can make the impact force The conveyor belt then drives the item to impact the guide plate. This impact force causes the guide plate to drive the curved rod to move inside the curved shell, compressing the spring. The spring's elasticity reduces the impact force, slowing down the fast-moving item to prevent damage, and then allowing it to enter the defective area. By setting up the good and defective areas and using the rotation of the guide plate to guide them, the device can accurately direct good and defective items to different areas, improving sorting accuracy and efficiency. At the same time, when an item hits the guide plate, the guide plate compresses the spring through the curved rod. The spring's elasticity reduces the impact force and slows down the item's movement, effectively preventing damage to the item due to rapid movement and impact, and protecting the item.

It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.
[0025] like Figure 1-4 As shown, the technical solution adopted by the present invention is specifically as follows: a defective product separation structure includes a first bracket 1 and a second bracket 2, the first bracket 1 is provided with a conveyor belt 3, the second bracket 2 is provided with a blanking plate 4 in contact with the conveyor belt 3, a partition plate 5 is provided at the center of the blanking plate 4, the partition plate 5 divides the blanking plate 4 into a good product area 6 and a defective product area 7, and a material guide component is provided on the partition plate 5;
[0026] The material guide assembly includes two fixed blocks 8 provided on the partition plate 5, a rotating assembly provided on the two fixed blocks 8, a connecting rod provided on the rotating assembly, a material guide plate 9 provided at one end of the connecting rod, and an elastic assembly provided between the material guide plate 9 and the partition plate 5;
[0027] The elastic component includes an arc-shaped shell 10 connected to the partition plate 5 and an arc-shaped rod 11 connected to the guide plate 9. A spring 12 is provided inside the arc-shaped shell 10, and one side of the spring 12 is connected to the arc-shaped rod 11 located inside the arc-shaped shell 10.
[0028] Its working principle is: first, place the object on the conveyor belt 3, and after detection, determine whether the object is a good product or a defective product. If it is a good product, the rotating component rotates at this time, and the rotating component drives the connecting rod to rotate the guide plate 9 to a certain angle. When the guide plate 9 rotates, it drives the arc rod 11 to move inside the arc shell 10, thereby squeezing the spring 12, so that the spring 12 has elasticity, and then the defective area 7 is sealed. At this time, the guide plate 9 and the good product area 6 form a good product guiding channel. At the same time, the conveyor belt 3 drives the object to first hit the guide plate 9. This impact force will again cause the guide plate 9 to drive the arc rod 11 to move inside the arc shell 10 to squeeze the spring 12. The elastic force of the spring 12 can It can reduce the impact force, thereby slowing down the speed of fast-moving items to prevent damage, and then enter the good product area 6. According to the same principle, when an item is judged as defective, the rotating component drives the guide plate 9 to rotate in the opposite direction, and then moves inside the arc-shaped shell 10 through the arc-shaped rod 11, thereby squeezing the spring 12, so that the spring 12 has elasticity and seals the good product area 6. Then the conveyor belt 3 drives the item to first hit the guide plate 9. This impact force will again cause the guide plate 9 to drive the arc-shaped rod 11 to move inside the arc-shaped shell 10 to squeeze the spring 12. The elastic force of the spring 12 can reduce the impact force, thereby slowing down the speed of fast-moving items to prevent damage, and then enter the defective product area 7. The device is capable of accurately directing good products and defective products to different areas by setting a good product area 6 and a defective product area 7 and utilizing the rotation of a guide plate 9 for guidance, thereby improving the accuracy and efficiency of sorting. At the same time, when an article hits the guide plate 9, the guide plate 9 squeezes the spring 12 through the arc rod 11. The elastic force of the spring 12 can reduce the impact force and slow down the movement speed of the article, thereby effectively preventing the article from being damaged due to rapid movement and impact, and protecting the article.
[0029] Wherein, protective plates 13 are provided on both the conveyor belt 3 and the blanking plate 4, and the protective plates 13 can prevent objects from falling during movement.
[0030] At the same time, the rotating assembly includes a rotating shaft 14 that is rotatably arranged between the two fixed blocks 8. A motor 15 connected to one of the fixed blocks 8 is provided on the rotating shaft 14, and the outer side of the rotating shaft 14 is connected to the connecting rod. The rotating shaft 14 is driven to rotate by the motor 15, and the rotating shaft 14 drives the connecting rod to rotate the guide plate 9.
[0031] The guide plate 9 is provided with a first smooth surface, which can reduce friction and enable the items to be quickly guided out.
[0032] A second smooth surface is provided inside the good product area 6 and the bad product area 7. This arrangement can reduce friction and enable the items to be quickly discharged.
[0033] The center of the arc rod 11 is the same as the center of the rotating shaft 14. This setting enables the rotating shaft 14 to drive the guide plate 9 to rotate with a trajectory that is the same as the trajectory of the arc rod 11 inside the arc shell 10, ensuring that the arc rod 11 can rotate inside the arc shell 10.
[0034] The conveyor belt 3 is a conventional technology in which a motor 15 drives a rotating shaft to rotate, and then the conveyor belt 3 drives another rotating shaft to rotate, thereby conveying items. This belongs to the conventional technology and will not be described in detail here.
[0035] A buffer layer is provided on the guide plate 9, which can further reduce the impact force, thereby effectively preventing the objects from being damaged due to rapid movement and impact.
[0036] An automatic detection machine includes a third bracket 16. A support plate is provided on the top of the third bracket 16, and a detector is provided on the bottom of the support plate.
[0037] Detectors are machine vision cameras used to detect and remove defective products from industrial production processes. Using advanced technologies and algorithms, these devices can efficiently and accurately detect defects in products and automatically remove them, thereby improving production efficiency and product quality.
[0038] Machine vision is a key technology in industrial defect detection equipment. It uses cameras and image processing algorithms to capture and analyze product images in real time. Machine vision systems can identify surface defects such as cracks, scratches, and deformations, distinguishing them from qualified products. The application of machine vision inspection equipment enables rapid and accurate detection of surface defects in industrial products on high-speed production lines, significantly improving production efficiency.
[0039] Detectors include:
[0040] 1. Image acquisition module: Usually composed of high-quality industrial cameras, it is responsible for capturing real-time images of products moving on the production line and can identify surface defects such as cracks, scratches, and deformations.
[0041] 2. Lighting system: Provides uniform, stable and appropriate intensity of light to ensure that the collected images are clear and accurate, and reduce the impact of shadows and reflections on detection.
[0042] 3. Image processing unit: Contains high-performance computer hardware and dedicated image processing software, used for preliminary processing and analysis of the collected images.
[0043] 4. After making a judgment, drive the rotating component to work.
[0044] 5. Controller: controls the operation of the entire device, and its model is a controller (PLC) that can be changed.
[0045] It should be noted that the detector is an existing technology, such as automatic product appearance detection equipment, and will not be described in detail here.
[0046] When the entire device is running, the object is first placed on the conveyor belt 3 and then transported to the bottom of the detector. The conveyor belt 3 stops working (controlled by the sensor), and then the detector determines whether the object is good or defective.
[0047] The working principle of the utility model is as follows: first, an object is placed on the conveyor belt 3, and the object is detected to determine whether it is a good product or a defective product. If it is a good product, the rotating component rotates at this time, and the rotating component drives the connecting rod to rotate the guide plate 9 to a certain angle. When the guide plate 9 rotates, it drives the arc rod 11 to move inside the arc shell 10, thereby squeezing the spring 12, so that the spring 12 has elasticity, and then the defective product area 7 is sealed. At this time, the guide plate 9 and the good product area 6 form a good product guiding channel. At the same time, the conveyor belt 3 drives the object to first hit the guide plate 9. This impact force will again cause the guide plate 9 to drive the arc rod 11 to move inside the arc shell 10 to squeeze the spring 12. Through the elastic force of the spring 12 It can reduce the impact force, thereby slowing down the movement of fast-moving items to prevent damage, and then enter the good product area 6. According to the same principle, when an item is judged as defective, the rotating component drives the guide plate 9 to rotate in the opposite direction, and then moves inside the arc-shaped shell 10 through the arc-shaped rod 11, thereby squeezing the spring 12, so that the spring 12 has elasticity and seals the good product area 6. Then the conveyor belt 3 drives the item to first collide with the guide plate 9. This impact force will again cause the guide plate 9 to drive the arc-shaped rod 11 to move inside the arc-shaped shell 10 to squeeze the spring 12. The elastic force of the spring 12 can reduce the impact force, thereby slowing down the movement of fast-moving items to prevent damage, and then enter the defective product area 7. The device is capable of accurately directing good products and defective products to different areas by setting a good product area 6 and a defective product area 7 and utilizing the rotation of a guide plate 9 for guidance, thereby improving the accuracy and efficiency of sorting. At the same time, when an article hits the guide plate 9, the guide plate 9 squeezes the spring 12 through the arc rod 11. The elastic force of the spring 12 can reduce the impact force and slow down the movement speed of the article, thereby effectively preventing the article from being damaged due to rapid movement and impact, and protecting the article.
[0048] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
