Description

Technical Field

[0001] This utility model relates to the field of defect detection technology, and more specifically to an automated detection device for defects on the surface of conductive sheets. Background Technology

[0002] In modern industrial production, conductive sheets are a crucial electronic component widely used in various electronic devices, power systems, and new energy fields. Their quality directly affects the performance, safety, and reliability of the entire product. However, during the production process of conductive sheets, various defects inevitably occur on the surface due to factors such as uneven raw material texture, limitations in processing technology, and the complexity of the production environment. These defects include scratches, pits, holes, cracks, and stains. These surface defects not only affect the appearance of the conductive sheet but, more importantly, have a serious negative impact on its conductivity, mechanical properties, and the stability of its connection with other components. Therefore, machine vision inspection technology is needed to detect defects such as spots, pits, scratches, color differences, and breaks on the surface of conductive sheets.

[0003] As shown in the prior art published in CN210005456U, although this prior art can detect defects on the surface of products and remove defective products from the feeding port using a pusher cylinder, it has a high degree of automation and can effectively improve product inspection efficiency. However, this prior art adjusts the vision inspection camera and supplementary light through the assembly of clamps, and the assembly operation of the clamps is relatively cumbersome, requiring repeated tightening and loosening of screws for disassembly and adjustment, which affects assembly efficiency and ease of operation. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides an automated detection device for surface defects of conductive sheets. By pulling the handle outward, the connecting post and the locking post move outward. The connecting post is compressed by the positioning post against the spring, simultaneously adjusting the height of the adjustment frame, which is not limited by the locking post. Then, the spring's rebound force pushes the positioning post and the connecting post inward. The connecting post causes the locking post on the handle to insert into the corresponding slot. The engagement of the locking post and the slot fixes the adjustment frame, thereby achieving height adjustment of the visual inspection camera and the supplementary light. The overall operation is simple and convenient, effectively improving adjustment efficiency and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated detection device for surface defects of conductive sheets, including a conveying component for conveying to the conductive sheet, and a detection component for surface defect detection is provided outside the conveying component, the detection component being height-adjustable by an adjusting component;

[0006] The adjusting component includes a vertical plate located at the top of the rear end of the conveyor, with multiple slots on the rear side of the vertical plate and two sets of engaging components on the outside of the vertical plate.

[0007] Each set of locking components includes an adjustment frame sleeved on the outside of the vertical plate. The adjustment frame has two mirror-distributed cavities inside. From front to back, each cavity has a limiting post, a connecting post, and a spring. The spring is sleeved on the outside of the connecting post.

[0008] Both connecting posts have their rear ends passing through the adjustment frame and are fitted with the same handle. The front side of the handle has a locking post that passes through the adjustment frame and extends into one of the slots.

[0009] In a preferred embodiment, the conveyor includes two mounting plates, with a belt conveyor for conveying conductive sheets mounted between the two mounting plates. The vertical plate is located at the top rear end of the belt conveyor, and a servo motor for driving the belt conveyor is mounted on the outside of one of the mounting plates.

[0010] In a preferred embodiment, the belt conveyor is externally equipped with a plurality of spaced-apart material distribution plates, and a storage area for placing conductive sheets is provided between two adjacent material distribution plates.

[0011] In a preferred embodiment, the detection component includes a top plate disposed at the top of the rear end of the belt conveyor, with the top of the vertical plate fixed to the bottom of the top plate. The bottom of the top plate is provided with a mounting base and a mounting ring. A visual inspection camera is mounted at the bottom of the mounting base, and a supplementary light is mounted at the bottom of the mounting ring.

[0012] The rear end of the mounting base is fixed to the front side of one of the adjustment frames, and the rear end of the mounting ring is movably connected to the other adjustment frame via a movable component.

[0013] In a preferred embodiment, the movable component includes a connecting shaft mounted on the rear side of the mounting ring, and the rear end of the connecting shaft is movably connected to the front side of one of the adjustment frames via a bearing. A driven gear is sleeved on the outside of the connecting shaft, and a master gear meshes with the top of the driven gear. A micro motor for driving the master gear is mounted on the top of the front end of the adjustment frame.

[0014] In a preferred embodiment, each of the four corners of the bottom of the top plate is equipped with a support column, and each support column is equipped with a support plate at its bottom. The support plate is installed on the side of the mounting plate away from the belt conveyor.

[0015] In a preferred embodiment, a cross plate for fixing an electric push rod is installed between two support plates, and a push plate for separating defective products is installed at the end of the electric push rod near the belt conveyor. A collection box for storing defective products is provided between the other two support plates.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By pulling the handle outward, the connecting column and the locking column move outward. The connecting column is compressed by the positioning column, and the height of the adjustment frame, which is not limited by the locking column, is adjusted. Then, the spring's rebound force pushes the positioning column and the connecting column inward. The connecting column drives the locking column on the handle to insert into the corresponding slot. The engagement of the locking column and the slot fixes the adjustment frame, thereby realizing the height adjustment of the visual inspection camera and the supplementary light. The overall operation is simple and convenient, and can effectively improve the adjustment efficiency.

[0018] 2. The main gear is driven by a micro motor to rotate. The main gear drives the connecting shaft to rotate through the meshing driven gear.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Refer to the instruction manual appendix Figure 1-5 This utility model provides an automated detection device for surface defects of conductive sheets, including a conveyor for conveying conductive sheets. The conveyor includes two mounting plates 10, and a belt conveyor 11 for conveying conductive sheets is installed between the two mounting plates 10. The vertical plate 1 is located at the top of the rear end of the belt conveyor 11, and a servo motor 12 for driving the belt conveyor 11 is installed on the outside of one of the mounting plates 10.

[0027] When using the belt conveyor 11 to transport conductive sheets for surface defect detection, multiple spaced distribution plates 13 are installed on the outside of the belt conveyor 11. A placement area 14 for placing conductive sheets is provided between two adjacent distribution plates 13. The conductive sheets can be placed between two distribution plates 13, and then the distribution plates 13 separate the conductive sheets to avoid them being stacked haphazardly, thereby ensuring the detection effect of the conductive sheets. Then, the belt conveyor 11 is driven by the servo motor 12 to transport the conductive sheets to the bottom of the test piece for surface defect detection.

[0028] like Figure 1-3 As shown, when the conductive sheet is conveyed to the bottom of the inspection piece, a visual inspection camera 18 is needed to perform defect detection. Therefore, an inspection piece for surface defect detection is provided on the outside of the conveyor. The inspection piece includes a top plate 15 located at the top of the rear end of the belt conveyor 11, and the top of the vertical plate 1 is fixed to the bottom of the top plate 15. The bottom of the top plate 15 is provided with a mounting plate 10 and a mounting ring 17. The visual inspection camera 18 is mounted on the bottom of the mounting plate 10, and a supplementary light 19 is mounted on the bottom of the mounting ring 17. The rear end of the mounting plate 10 is fixed to the front side of one of the adjustment frames 3, and the rear end of the mounting ring 17 is movably connected to another adjustment frame 3 through a movable part. Supplementary lighting is provided by the supplementary light 19, so that the visual inspection camera 18 can better inspect the conductive sheet, thereby ensuring the accuracy of the inspection.

[0029] Furthermore, the movable component includes a connecting shaft 20 installed on the rear side of the mounting ring 17, and the rear end of the connecting shaft 20 is movably connected to the front side of one of the adjustment frames 3 via a bearing. A driven gear 21 is sleeved on the outside of the connecting shaft 20, and a main gear 22 meshes with the top of the driven gear 21. A micro motor 23 for driving the main gear 22 is installed on the top front end of the adjustment frame 3. Thus, the micro motor 23 can drive the main gear 22 to rotate. The main gear 22 drives the connecting shaft 20 to rotate through the meshing driven gear 21. The connecting shaft 20 then drives the supplementary light 19 on the mounting ring 17 to rotate, thereby achieving the effect of adjusting the illumination angle of the supplementary light 19. The angled light can highlight surface scratches and make defects more obvious, thereby improving the detection effect.

[0030] To prevent conductive sheets with surface defects from mixing with intact conductive sheets, it is necessary to separate the conductive sheets with surface defects, such as... Figure 2 As shown, each of the four corners of the bottom of the top plate 15 is equipped with a support column 24, and each support column 24 is equipped with a support plate 25 at its bottom. The support plate 25 is installed on the side of the mounting plate 10 away from the belt conveyor 11. A horizontal plate 27 for fixing an electric push rod 26 is installed between two support plates 25, and a push plate 28 for separating defective products is installed at the end of the electric push rod 26 near the belt conveyor 11. A collection box 29 for storing defective products is provided between the other two support plates 25. The top plate 15 is fixed by the support plates 25 and the support columns 24 to ensure the stability of the top plate 15. When a defect is detected on the surface of the conductive sheet, the electric push rod 26 extends and drives the push plate 28 to push the conductive sheet and push it into the collection box 29, thereby separating the conductive sheet with surface defects from the intact conductive sheet.

[0031] To improve the detection results, the height and distance of the visual inspection camera 18 and the supplementary light 19 need to be adjusted, such as... Figure 3-5 As shown, the height of the detection component is adjusted by an adjusting component; the adjusting component includes a vertical plate 1 located at the top of the rear end of the conveyor component, a plurality of slots 2 are provided on the rear side of the vertical plate 1, and two sets of engaging components are provided on the outside of the vertical plate 1; each set of engaging components includes an adjusting frame 3 sleeved on the outside of the vertical plate 1, and two mirror-distributed cavities 4 are provided inside the adjusting frame 3, and a limiting post 5, a connecting post 6 and a spring 7 are arranged sequentially from front to back inside the cavity 4, and the spring 7 is sleeved on the outside of the connecting post 6; the rear ends of the two connecting posts 6 pass through the adjusting frame 3 and are equipped with the same handle 8, and a locking post 9 is installed on the front side of the handle 8, passing through the adjusting frame 3 and extending into one of the slots 2.

[0032] When adjusting the visual inspection camera 18 and the supplementary light 19, the connecting post 6 and the locking post 9 are moved outward by pulling the handle 8. The connecting post 6 is compressed by the limiting post 5, and the locking post 9 is separated from the slot 2. This facilitates the height adjustment of the unrestricted adjustment frame 3. After adjustment, the spring 7 pushes the limiting post 5 and the connecting post 6 inward by the rebound force. The connecting post 6 then drives the locking post 9 on the handle 8 to insert into the corresponding slot 2. The engagement of the locking post 9 and the slot 2 fixes the adjustment frame 3, thereby realizing the height adjustment of the visual inspection camera 18 and the supplementary light 19. The operation is simple and convenient, and can effectively improve the adjustment efficiency.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
