Description

Technical Field

[0001] This application relates to the field of semiconductor component processing technology, and in particular to a square battery appearance inspection device. Background Technology

[0002] With market demand, prismatic batteries are widely used due to their high energy density and good thermal stability. However, during the production process, the quality of the battery's appearance directly affects the performance and safety of the final product. Therefore, accurate and rapid detection of appearance defects is crucial for improving production efficiency. Traditional visual inspection methods are not only time-consuming and labor-intensive, but also prone to increased false positive rates due to human eye fatigue, making them unsuitable for the needs of modern manufacturing.

[0003] Currently, battery appearance inspection typically uses cameras to capture images of the battery surface and image processing algorithms to identify defects. While this method improves inspection speed and accuracy, due to the inherent structural characteristics of square batteries, when the batteries are fixed in place, the camera can only inspect each flat surface. After inspecting all six flat surfaces, it cannot accurately inspect the edges or corners of the battery, thus hindering automation and resulting in low inspection efficiency. Utility Model Content

[0010] Optionally, one side of the arc-shaped guide seat is also provided with a stator arc magnetic rail that extends synchronously therewith. The stator arc magnetic rail, the arc-shaped guide seat, and the arc guide rail are all concentric and extend in the same direction. The slide plate is provided with a moving element unit corresponding to the stator arc magnetic rail.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a square battery appearance inspection device.

[0027] Reference Figure 1 and Figure 2 A square battery appearance inspection device includes an inspection mechanism 1 and a clamping mechanism 2. The clamping mechanism 2 is used to fix the position of the square battery, and the inspection mechanism 1 is used to inspect the appearance of the square battery. The inspection mechanism 1 includes a fixed base 11 and an inspection camera 12. The fixed base 11 is provided with an arc-shaped guide seat 13, and the inspection camera 12 moves in an arc along the arc-shaped guide seat 13.

[0028] The clamping mechanism 2 includes a limiting part 21 and a clamping unit 22 corresponding to the limiting part 21, and the square battery is located in the clamping area between the limiting part 21 and the clamping unit 22;

[0029] The clamping mechanism 2 is located at the center of the arc-shaped guide seat 13. During the movement of the detection camera 12, its detection direction is always towards the clamping mechanism 2. When the square battery is in a fixed position, the detection camera 12 can move in an arc around the square battery, thereby realizing the appearance inspection of the square battery and detecting the edges or top corners of the square battery. Compared with the planar detection method of square batteries in the prior art, it is more accurate.

[0030] like Figure 3As shown, in order to enable the detection camera 12 to move in an arc on the arc guide seat 13, the arc guide seat 13 is provided with an arc guide rail 14 and a slider 15 that moves along the arc guide rail 14. The slider 15 is provided with a sliding plate 16 that moves synchronously with it. The detection camera 12 is fixedly installed on the sliding plate 16. When the slider 15 moves in an arc on the arc guide rail 14, the sliding plate 16 moves synchronously, thereby realizing the synchronous movement of the camera.

[0031] Furthermore, to enable the slider 15 to move in an arc shape on the arc-shaped guide rail 14, a stator arc magnetic rail 17 extending synchronously is provided on the outer arc of the arc-shaped guide seat 13; a moving unit 18 corresponding to the stator arc magnetic rail 17 is provided on the slide plate 16, the moving unit 18 is fixedly connected to the slide plate 16, and the two move synchronously, with the moving unit 18 connected to an external power supply. The relative arrangement of the moving unit 18 and the stator arc magnetic rail 17, and the fact that the moving unit 18 can reciprocate on the stator arc magnetic rail 17 after being connected to an external power supply, and serves as the driving source for the slide plate 16 and the slider 15, should be a conventional technical means known to those skilled in the art, and will not be described in detail here. The stator arc magnetic track 17, arc guide seat 13, and arc guide rail 14 are all concentric and extend in the same direction. During the movement of the moving unit 18, the slide plate 16, which is fixedly connected to the moving unit 18, moves synchronously. The slider 15 installed on the slide plate 16 also moves synchronously along the arc guide rail 14, realizing the arc movement of the slide plate 16, thereby enabling the detection camera 12 on the slide plate 16 to move in an arc.

[0032] Furthermore, the slide plate 16 is provided with a mover mounting seat 19 for fixing the mover unit 18. The mover mounting seat 19 is located near the outer wall of the stator arc magnetic rail 17 and extends synchronously with the stator arc magnetic rail 17 along the arc direction. The slide plate 16 has a fan-shaped structure, and the mover unit 18 and the mover mounting seat 19 have an L-shaped structure. The mover mounting seat 19 is installed and connected to the outer wall of the slide plate 16. During the movement of the mover unit 18, the mover mounting seat 19 always stays close to the stator arc magnetic rail 17, ensuring the accuracy and stability of the movement of the slide plate 16.

[0033] To ensure the reciprocating movement of the slide plate 16 within its travel range and to guarantee operational safety, limit blocks 3 are provided at both ends of the arc-shaped guide seat 13. The limit blocks 3 are located at the extreme positions of the slide plate 16's movement, and anti-collision pads 31 are also provided on the limit blocks 3. A limit sensor 4 is also installed on the slide plate 16 to detect the position of the limit blocks 3. When the slide plate 16 moves to its extreme position, the limit sensor 4 detects the movement position of the slide plate 16. This structure is existing conventional technology and will not be described in detail here.

[0034] For example Figure 4As shown, the clamping mechanism 2 also includes a support frame 23. The limiting part 21 and the clamping unit 22 are both mounted on the support frame 23. The clamping area is at the same height as the detection area of ​​the detection camera 12, ensuring that the square battery is always within the detection range of the detection camera 12.

[0035] The square battery is placed horizontally in the clamping area. The limiting part 21 includes two adjacent limiting short plates 24. The clamping unit 22 includes two pneumatic pressure plates 25. The pneumatic pressure plates 25 are driven by a cylinder. The limiting short plates 24 and the pneumatic pressure plates 25 are correspondingly arranged. The pneumatic pressure plates 25 are driven by the cylinder to move towards the corresponding limiting baffle to fix the position of the square battery. After the square battery is fixed, the limiting short plates 24 and the pneumatic pressure plates 25 abut against part of the side of the square battery. The two limiting short plates 24 are adjacent to each other, and their height and length are both less than the height and length of each plane of the square battery. The square battery is fixed by the clamping mechanism 2. At least one edge of the square battery is not blocked by the limiting short plate 24 and is completely located in the detection area of ​​the detection camera 12, which facilitates the detection camera 12 to detect its edge or top corner.

[0036] For example Figure 5 As shown, the square battery can be placed vertically on the clamping mechanism 2 and fixed by the limiting short plate 24 and the pneumatic pressure plate 25. At the same time, at least one edge of the square battery is completely located within the detection area of ​​the detection camera 12.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
