Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic film detection, and particularly relates to a defect detection device for an aluminum-plastic film. Background Art

[0002] The aluminum-plastic film is used for packaging battery cells, has the characteristic of light weight, is an important material for encapsulating batteries, plays a crucial role in the quality of batteries, and can greatly improve the specific energy of batteries. At the same time, it also has flexibility, can effectively reduce the internal pressure of the battery, and reduce the risk of explosion. Generally, the aluminum-plastic film is mainly divided into three layers, namely an outer protective layer, an aluminum layer and a heat-sealing layer. After the aluminum-plastic film undergoes the processes of punching and forming and cutting, it can be used for battery encapsulation. Before battery encapsulation, it is necessary to detect the defects of the aluminum-plastic film. After the existing aluminum-plastic film is punched and formed, the heat-sealing layer is easily damaged mechanically. Generally, it is detected by the naked eye of workers. However, some damages cannot even be identified by the naked eye, which leads to defective products flowing into the subsequent processes;

[0003] With the development of technology, by using fill lights to supplement light for the detected aluminum-plastic film, a camera is used to capture and collect the situation on the surface of the heat-sealing layer of the aluminum-plastic film, and automatic monitoring replaces manual visual inspection, which is convenient to operate and the detection is more delicate;

[0004] However, when the existing automatic detection of aluminum-plastic film is carried out, generally, after the aluminum-plastic film is placed on the detection table, after the detection by the camera is completed, the aluminum-plastic film is taken off the detection table, and then according to the detection results, the aluminum-plastic film is classified into a qualified collection box and a defect collection box, and then, for subsequent feeding, which results in a long operation time and affects the detection efficiency. Therefore, it is urgent to design a defect detection device for an aluminum-plastic film to solve the above problems. Summary of the Utility Model

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a defect detection device for aluminum-plastic film provided by an embodiment of the present utility model includes a detection mechanism 1 and two groups of conveyor mechanisms 2. There are several feeding trays 9 arranged between the two groups of conveyor mechanisms 2. A feeding groove 10 is opened on the upper side of the feeding tray 9. The feeding groove 10 is used for placing the aluminum-plastic film and limiting it. A guide groove is opened on the lower side of the feeding groove 10. A guide rod 20 is slidably installed in the guide groove. The number of the guide grooves and the guide rods 20 is three each. The guide grooves and the guide rods 20 are used to guide the linear movement of the lifting plate 11. The upper side of the guide rod 20 is fixedly installed with a lifting plate 11. The lifting plate 11 is movably installed in the feeding groove 10. A circular rod 13 is arranged on the lower side of the guide rod 20. A fixed plate 14 is arranged between the two groups of conveyor mechanisms 2. An electric push rod 15 is arranged on the upper side of the fixed plate 14. The electric push rod 15 is fixedly installed on the upper side of the rear end of the fixed plate 14. The output end of the electric push rod 15 is fixedly installed with an arc plate 16. The arc plate 16 is adapted to the circular rod 13. An installation frame 17 is arranged on one side of one of the two groups of conveyor mechanisms 2. An electric telescopic rod 18 is arranged on the upper side of the installation frame 17. The output end of the electric telescopic rod 18 is fixedly installed with a push plate 19. The positions of the electric telescopic rod 18 and the push plate 19 correspond to those of the electric push rod 15. The conveyor mechanism 2 includes an installation frame 3, a driving motor 4, a rotating shaft 5 and a conveyor belt 6. The driving motor 4 is fixedly installed on one side of the installation frame 3. The driving motor 4 is installed on one side of the installation frame 3 through an installation plate. The number of the rotating shafts 5 is two. The two rotating shafts 5 are rotatably installed on the other side of the installation frame 3. The two rotating shafts 5 are rotatably installed at one side of the two ends of the installation frame 3. The output end of the driving motor 4 is fixedly connected to one of the rotating shafts 5. The conveyor belt 6 is sleeved between the two rotating shafts 5. Fixed rods 12 are fixedly installed on both sides of the feeding tray 9. The two fixed rods 12 are respectively fixedly connected to one side of the two conveyor belts 6. The fixed plate 14 is fixedly installed between the two installation frames 3. Two support frames 7 are fixedly installed between the two installation frames 3. The support frames 7 are used to support the two installation frames 3.

[0025] Specifically, in this embodiment, the aluminum-plastic film is placed in the feeding groove 10 on the feeding tray 9, and the aluminum-plastic film is limited by the feeding groove 10. Then, by starting two driving motors 4, the two driving motors 4 drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the conveyor belt 6 to rotate, and the rotation of the conveyor belt 6 drives several feeding trays 9 to move. Through the movement of several feeding trays 9, continuous feeding can be carried out. When the feeding tray 9 with the aluminum-plastic film moves to the lower side of the detection mechanism 1, the driving motor 4 is turned off. Then, the detection mechanism 1 is started again to automatically detect the aluminum-plastic film. After the detection is completed, the driving motor 4 is started again, so that the conveyor belt 6 drives the feeding tray 9 to move forward. Then, the subsequent feeding trays 9 are moved to the lower side of the detection mechanism 1, and the driving motor 4 is turned off again to enable the detection mechanism 1 to detect the aluminum-plastic film. At the same time, according to the detection result, when a defective aluminum-plastic film is detected, the electric push rod 15 is first started, so that the electric push rod 15 drives the arc-shaped plate 16 to move upward. The upward movement of the arc-shaped plate 16 can push the circular rod 13, so that the circular rod 13 drives the guide rod 20 and the lifting plate 11 to eject the aluminum-plastic film out of the feeding tray 9. Then, the electric telescopic rod 18 is started, so that the electric telescopic rod 18 drives the push plate 18 to move. The movement of the push plate 18 can push the aluminum-plastic film into the previously placed defective product collection box. Similarly, when the aluminum-plastic film is detected as a qualified product, the electric push rod 15 and the electric telescopic rod 18 will not be started, and the qualified aluminum-plastic film will follow. The feeding tray 9 continues to move. When it moves to the rear end of the conveyor belt 6 and the feeding tray 9 is turned over, the aluminum-plastic film will automatically fall into the previously placed qualified product collection box. Then, by repeating the above steps, the aluminum-plastic film can be continuously detected, and at the same time, the good and bad products of the aluminum-plastic film can be automatically classified, improving the detection efficiency of the aluminum-plastic film.

[0026] A defect detection device for an aluminum-plastic film provided by the present utility model, the detection mechanism 1 includes a fixed frame 22, a cylinder 23, a light-shielding cover 24 and a detection camera 25. The fixed frame 22 is arranged on the upper side of the installation frame 3. The cylinder 23 is fixedly installed on the upper side of the fixed frame 22. The light-shielding cover 24 is arranged on the lower side of the fixed frame 22, and the light-shielding cover 24 is fixedly connected to the output end of the cylinder 23. The detection camera 25 is arranged on the top of the inner wall of the light-shielding cover 24. There are two supplementary light lamps 26 arranged on the top of the inner wall of the light-shielding cover 24, and the two supplementary light lamps 26 are respectively located on both sides of the detection camera 25. The light-shielding cover 24 corresponds to the feeding tray 9. A sealing plug plate 27 is arranged on the lower side of the light-shielding cover 24, and a sealing groove 21 is arranged on the upper side of the feeding tray 9. The sealing plug plate 27 corresponds to the sealing groove 21.

[0027] In another embodiment provided by the present utility model, during detection, the cylinder 23 is activated to drive the light-shielding cover 24 to move downward, so that the light-shielding cover 24 contacts the upper side of the material feeding tray. At the same time, the sealing plug plate 27 is inserted into the sealing groove 21 to form a sealed dark space. Then, the supplementary light lamp 26 is turned on to supplement light to the aluminum-plastic film to be detected. At this time, the detection camera 25 is activated to photograph and collect the condition of the heat-sealing layer surface of the aluminum-plastic film. Then, the processor analyzes and processes the collected information to further determine whether there are defects in the aluminum-plastic film.

[0028] Working principle: The conveying mechanism 2 conveys the aluminum-plastic film in the material feeding tray 9, and then conveys the aluminum-plastic film to the lower side of the detection mechanism 1. Then, the detection mechanism 1 is activated to detect the aluminum-plastic film. When a defect is detected in the aluminum-plastic film, the electric push rod 15 drives the jacking plate 11 to jack out the aluminum-plastic film from the material feeding tray 9. Then, the electric telescopic rod 18 is activated to drive the push plate 18 to move. The movement of the push plate 18 can push the aluminum-plastic film into the pre-placed defect collection box, so that while continuously detecting the aluminum-plastic film, it can also automatically classify the aluminum-plastic film into good and bad products.

[0029] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
