Description

Technical Field

[0001] This utility model relates to the field of battery testing, and more specifically, to a battery appearance testing device. Background Technology

[0002] In the battery production process, a crucial step before finished batteries leave the factory is appearance inspection, which significantly impacts the quality control of the finished batteries. Traditionally, appearance inspection is done manually; however, manual inspection is inefficient and susceptible to visual errors, leading to a high risk of false positives and false negatives. Therefore, manufacturers have introduced battery appearance inspection devices to improve the efficiency and quality of inspection.

[0003] However, existing battery appearance inspection devices, such as the Chinese national patent (application number: CN202311197850.0), use a gripping and rotating mechanism to clamp and rotate the two ends of the battery, and use a vision inspection device to inspect the two ends of the battery. Then, the battery that has been inspected in the end face inspection area will enter the side edge inspection area. The gripping and flipping mechanism can continue to grip the battery and can rotate and flip it. The vision inspection device inspects the edges and flipped surfaces. It requires flipping and rotating the battery to inspect all surfaces. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In addition, the directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. The directional terms are used to better and more clearly explain and understand this utility model, and are not intended to indicate or imply the necessary orientation of this utility model. Therefore, they should not be construed as limitations on this utility model.

[0025] Examples of embodiments of this utility model Figures 1 to 7As shown, a battery appearance inspection device includes a loading station, a first inspection station, a unloading station, and a second inspection station. The loading station is equipped with a first moving platform 1, which is a linear slide. A first rotating mechanism 10 is mounted on the first moving platform 1. The loading station, first inspection station, and unloading station are arranged sequentially from left to right. The first moving platform 1 drives the first rotating mechanism 10 to move between the loading station, first inspection station, and unloading station, i.e., the first moving platform 1 extends in the left-right direction. The first inspection station is equipped with a first camera 11 that inspects the top and side appearance of the battery on the first rotating mechanism 10, and a first bracket 12 that supports the first camera 11. The first bracket 12 is located behind the first moving platform 1. The optical axis of the first camera 11 forms an angle of 30° to 60° with the top surface of the battery on the first rotating mechanism 10. The first moving platform 1 drives the first rotating mechanism 10 to move from left to right, allowing the first camera 11 to capture images of the battery. At this time, the first camera 11 is located to the upper right of the first rotating mechanism 10. Then, the first camera 11 can perform appearance inspection, and the first rotating mechanism 10 drives the battery to rotate, so that the first camera 11 can detect the appearance of the battery from different sides and the appearance of the top surface of the battery from different angles. The unloading station is provided with an unloading mechanism 5 that moves the battery from the first rotating mechanism 10 to the second inspection station. The unloading mechanism 5 is located on the right rear side of the first moving platform 1. The unloading mechanism 5 is provided with a second rotating mechanism 6 that drives the battery to rotate. The second inspection station is provided with a second camera 60 that detects the bottom and sides of the battery on the unloading mechanism 5. The unloading mechanism 5 clamps the battery to expose the bottom surface of the battery. The optical axis of the second camera 60 makes an angle of 30° to 60° with the bottom surface of the battery on the unloading mechanism 5. At this time, the second camera 60 is located in front of and below the second rotating mechanism 6. The second rotating mechanism 6 drives the battery to rotate to detect the bottom and sides of the battery from various angles. The first rotating mechanism 10 and the second rotating mechanism 6 are both hollow rotating platforms. Preferably, the first camera 11 and the second camera 60 are both cameras with CCD sensors.

[0026] When the battery is at the first inspection station, the first rotating mechanism 10 drives the battery to rotate, thereby inspecting the various angles of the top surface and the sides of the battery. Then, the unloading mechanism 5 moves the battery to the second inspection station, where the second rotating mechanism 6 drives the battery to rotate, thereby inspecting the various angles of the bottom surface and the sides of the battery. This device can complete the appearance inspection of all sides of the battery without flipping it, reducing the steps of flipping the battery and improving the inspection efficiency. At the same time, the absence of a battery-flipping mechanism reduces the size of the device.

[0027] The first rotating mechanism 10 and the second rotating mechanism 6 respectively drive the battery to rotate, thereby detecting various angles of the top, bottom and side surfaces of the battery, thus improving the accuracy of the detection. This device only needs two detections to complete the appearance detection of all surfaces of the battery, improving the detection efficiency. At the same time, this device only requires two cameras, reducing the size of the device. Furthermore, the angle between the camera and the battery allows the camera to avoid the interference of high light from the vertical reflection of the battery surface when taking pictures, thus obtaining a clearer detection image.

[0028] Further improvements, such as Figure 4 and Figure 5 As shown, the unloading mechanism 5 includes a second support 50, a vacuum suction cup 51 for adsorbing the battery, and a dual-axis moving platform 52 that moves in the XZ axis direction. The second support 50 is located on one side of the first moving platform 1, at the right rear side of the first moving platform 1. The dual-axis moving platform 52 is mounted on the second support 50, and the vacuum suction cup 51 is mounted on the second rotating mechanism 6. The unloading mechanism 5 adsorbs the battery through the vacuum suction cup 51, and then moves the battery away from the first rotating mechanism 10 through the dual-axis moving platform 52, and moves the battery to a position where the angle between the optical axis of the second camera 60 and the bottom surface of the battery is any angle between 30° and 60°.

[0029] Further improvements, such as Figure 1 and Figure 2 As shown, the first rotating mechanism 10 is also equipped with the vacuum suction cup 51. The battery is fixed by the vacuum suction cup 51 to prevent the battery from moving when the first rotating mechanism 10 rotates the battery, thereby avoiding affecting the inspection of the battery's appearance.

[0030] Further improvements, such as Figure 1 and Figure 3 As shown, the first bracket 12 is provided with a first slide rail 13 extending horizontally. Preferably, the first slide rail 13 is a ball-bearing linear guide rail. The first slide rail 13 extends in the left and right direction. There are two first slide rails 13, which are spaced apart in the vertical direction. A first mounting bracket 2 with a limit sliding is provided on the first slide rail 13. The upper and lower ends of the first mounting bracket 2 are respectively limited and slidably connected to the two first slide rails 13. The first camera 11 is mounted on the first mounting bracket 2.

The first illumination source 4 is located on the left side of the first slide rail 13, and the first camera 11 is located on the right side of the first slide rail 13. The first illumination source 4 faces the top surface of the battery on the first rotating mechanism 10. The first illumination source 4 provides supplementary lighting to the battery, making the detection image of the first camera 11 clearer.

[0032] Further improvements, such as Figure 1 and Figure 3 As shown, the first mounting bracket 2 includes a first slider 20 and a first connecting bracket 21. The first slider 20 is slidably mounted on the first slide rail 13.

The first connecting bracket 21 is slidably mounted on the first slider 20. The first camera 11 is mounted on the first connecting bracket 21. A first lead screw 3 extending vertically is rotatably mounted on the first slider 20. The first lead screw 3 is threadedly connected to the first connecting bracket 21. A first handwheel 30 is provided at one end of the first lead screw 3. The first handwheel 30 drives the first lead screw 3 to rotate, so that the first connecting bracket 21 drives the first camera 11 to move up and down. The position of the first camera 11 is adjusted by the ball bearing slider and the first lead screw 3, thereby adjusting the first camera 11 and making the detected image of the first camera 11 clearer.

[0033] Further improvements, such as Figure 4 and Figure 6 As shown, a third bracket 61 is provided below the feeding mechanism 5. A second slide rail 62 extending horizontally is provided on the third bracket 61. The second slide rail is also a ball-bearing linear guide rail. The second slide rail 62 extends in the front-to-back direction. There are two second slide rails 62, which are spaced apart in the vertical direction. A second mounting bracket 7 with limited sliding is provided on the second slide rail 62. The upper and lower ends of the second mounting bracket 7 are respectively limited and slidably connected to the two second slide rails 62. The second camera 60 is mounted on the second mounting bracket 7.

[0034] Further improvements, such as Figure 4 As shown, a second illumination source 9 with a limited sliding is provided on the second slide rail 62. The upper and lower ends of the second illumination source 9 are respectively provided on the ball sliders of the two second slide rails 62. The second illumination source 9 is located on the left side of the second slide rail 62, and the second camera 60 is located on the right side of the second slide rail 62. The second illumination source 9 faces the bottom surface of the battery on the unloading mechanism 5. The second illumination source 9 provides supplementary lighting to the battery, making the detection image of the second camera 60 clearer.

[0035] Further improvements, such as Figure 4 and Figure 6 As shown, the second mounting bracket 7 includes a second slider 70 and a second connecting bracket 71. The second slider 70 is slidably mounted on the second slide rail 62. The upper and lower ends of the second slider 70 are respectively mounted on ball bearing sliders on the two second slide rails 62. The second connecting bracket 71 is slidably mounted on the second slider 70. The second camera 60 is mounted on the second connecting bracket 71. A second lead screw 8 extending vertically is rotatably mounted on the second slider 70. The second lead screw 8 is threadedly connected to the second connecting bracket 71. A second handwheel 80 is provided at one end of the second lead screw 8. The second handwheel 80 drives the second lead screw 8 to rotate, causing the second connecting bracket 71 to move the second camera 60 up and down. The position of the second camera 60 is adjusted by the ball bearing slider and the second lead screw 8, thereby adjusting the second camera 60 and making the detected image of the second camera 60 clearer.
