Description

Technical Field

[0001] The utility model relates to the field of battery detection, and more specifically, to a foreign object detection platform for the production of battery blue films. Background Art

[0002] The battery cell is the most basic and important independent unit in a power battery. According to its shape, it can be mainly divided into three categories: square, cylindrical and soft-pack. In the vast majority of production processes, a protective film needs to be wrapped outside the battery cell, and because its color is blue, it is also called a blue film. The blue film is the last safety barrier of the battery. Therefore, during the production process, it is necessary to conduct a detailed inspection on whether there are defects and the form of the defects. Due to the influence of the process and the environment during the film wrapping process of the battery blue film, there is a probability that there are bump defects, that is, foreign object defects, on the surface after film wrapping. The foreign objects or bumps may be in the form of bubbles, soft foreign objects, hard foreign objects, etc. At present, it is necessary for production personnel to manually check the situation of foreign objects under the blue film, which consumes a lot of manpower and material resources.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] The working principle and technical effects of the above technical solution are as follows:

[0030] For the foreign object detection platform for battery blue film production of the present utility model, when detecting the battery blue film, the battery to be detected is placed on the detection table mechanism 2, and the detection table mechanism 2 is controlled to move the battery to directly below the image acquisition mechanism 3. Then, the alignment adjustment mechanism 4 is started, and the alignment adjustment mechanism 4 is used to align and center the battery on the detection table mechanism 2, so that the whole battery is located in the middle of the detection table mechanism 2. Then, the blowing and impurity removal mechanism 5 is controlled to start, and the surface of the battery blue film is blown by the blowing and impurity removal mechanism 5 to remove impurities such as dust on the surface of the battery blue film. Then, it is convenient to better take pictures of the battery through the image acquisition mechanism 3, acquire complete images, and transmit them to a display device for analysis. By manual visual judgment or calculation through relevant existing algorithms, it is convenient to more clearly judge whether there are foreign objects in the battery blue film. The alignment adjustment mechanism 4 is provided, which can align the battery placed on the detection table mechanism 2, making the acquired images clearer and more complete, and improving the image acquisition effect; the blowing and impurity removal mechanism 5 is also provided, which effectively removes the impurities on the outer surface of the battery blue film to be detected, prevents the impurities on the outer surface of the battery blue film from affecting the detection results, and improves the accuracy of detection.

[0031] The detection table mechanism 2 includes: a bearing table 21 slidably fitted on a linear guide on the cabinet 1, the bearing table 21 is connected to a lead screw seat plate 22, the lead screw seat plate 22 is threadedly connected to a driving lead screw 23, and the driving lead screw 23 is connected to the output shaft of a driving motor 24 fixed on the cabinet 1. After the driving lead screw 23 is started, it can drive the driving lead screw 23 to rotate. When the driving lead screw 23 rotates, the contact position between it and the lead screw seat plate 22 is changed, so as to drive the bearing table 21 to slide on the linear guide on the cabinet 1 through the lead screw seat plate 22, changing the position of the battery on the bearing table 21, making it more convenient for detection or taking and placing.

[0032] The image acquisition mechanism 3 includes: a CCD camera 31 electrically connected to the display screen.

The camera mounting plate 32 is connected to the upper end of the electric telescopic rod 33, and the lower end of the electric telescopic rod 33 is connected to the upper surface of the cabinet 1. A supplementary light lamp that irradiates toward the bearing table 21 is connected to the side of the camera mounting plate 32. The CCD camera 31 can be a camera purchased in the existing market, which can effectively collect images and transmit them to the display screen for analysis. The electric telescopic rod 33 can drive the camera mounting plate 32 to perform a lifting motion, thereby adjusting the horizontal height of the CCD camera 31 to meet the requirements of the CCD camera 31 for photographing and detecting different battery blue films and improving the photographing effect. A supplementary light lamp that irradiates toward the bearing table 21 is connected to the side of the camera mounting plate 32, which improves the photographing effect and solves the problem of poor photographing quality caused by insufficient light.

[0033] A rubber anti-slip pad is provided on the bearing table 21 to improve the stability of placing the battery.

[0034] The alignment adjustment mechanism 4 includes: alignment cylinders 41. Two alignment cylinders 41 are fixedly provided on the upper surface of the cabinet 1 relatively and are located on both sides of the bearing table 21. The output ends of the two alignment cylinders 41 are respectively connected to a sliding push plate 42, and alignment ejector rods 43 for abutting against the battery are connected to the adjacent sides of the two sliding push plates 42. The two alignment cylinders 41 can drive the two sliding push plates 42 to approach each other, and abut against both sides of the battery through the alignment ejector rods 43 on the inner sides of the two sliding push plates 42, so that the battery is basically located in the middle of the bearing table 21, improving the image acquisition effect.

[0035] The air-blowing impurity removal mechanism 5 includes: an impurity removal blower 51 disposed toward the bearing table 21. The impurity removal blower 51 is connected to the horizontal swing frame 52. The horizontal swing frame 52 is slidably connected to the transverse slideway of the chute seat 53. The chute seat 53 is fixedly provided on the cabinet 1, and the horizontal swing frame 52 is connected to the swing drive assembly installed on the cabinet 1. After the impurity removal blower 51 is started, it can blow and remove the impurities on the outer surface of the battery blue film to prevent the impurities on the outer surface of the battery blue film from affecting the detection result and improve the accuracy of detection. After the swing drive assembly is started, it can drive the horizontal swing frame 52 to perform a displacement motion in the left-right direction in the transverse slideway of the chute seat 53, so that the impurity removal blower 51 can also perform a displacement motion in the left-right direction driven by the horizontal swing frame 52, which is convenient for improving the blowing effect or effectively removing impurities from batteries of different sizes.

[0036] The swing drive assembly includes: a swing motor 54 connected to the side of the cabinet 1 through a motor base. A circular runner 55 is key-connected to the output shaft of the swing motor 54. An eccentric shaft 56 is connected to the eccentric position of the circular runner 55. The eccentric shaft 56 is slidably arranged in the vertical chute of the linkage frame 57. The middle part of the linkage frame 57 is slidably arranged in the limiting transverse chute of the chute seat 53. The linkage frame 57 is connected to the horizontal swing frame 52. An eccentric chute is provided on the circular runner 55. The eccentric shaft 56 is slidably connected in the eccentric chute. The eccentric shaft 56 is threadedly connected to the middle part of a screw rod 58. The screw rod 58 is rotatably connected in the eccentric chute. A screw is threadedly connected to the circular runner 55 and abuts against the screw rod 58.

[0037] The working principle and technical effects of the above technical solution are as follows:

[0038] In the foreign object detection platform for battery blue film production of the present utility model, after the swing motor 54 is started, it drives the circular runner 55 to rotate around its own axis. When the circular runner 55 rotates, it drives the eccentric shaft 56 to perform a rotational circular motion. When the eccentric shaft 56 rotates, it can change its contact position with the vertical chute of the linkage frame 57, thereby driving the linkage frame 57 to perform a displacement motion in the left-right direction in the limiting transverse chute of the chute seat 53. When the linkage frame 57 moves, it drives the horizontal swing frame 52 and the impurity removal fan 51 to perform a displacement motion in the left-right direction. Among them, the eccentric shaft 56 is threadedly connected to the middle part of the screw rod 58. Rotating the screw rod 58 can change its contact position with the eccentric shaft 56, thereby controlling the eccentric shaft 56 to slide in the eccentric chute of the circular runner 55, adjusting the distance between the eccentric shaft 56 and the center of the circular runner 55, and thus changing the distance of the displacement motion of the eccentric shaft 56 driving the linkage frame 57 in the left-right direction, and finally realizing the adjustment of the motion distance of the impurity removal fan 51, so that it is better suitable for the impurity cleaning of batteries of different sizes.
