Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a device for detecting damage to the negative electrode cover using a line scan camera. Background Technology

[0002] Button batteries are one of the important power supply components in electronic products, smart devices, and new energy fields. One of the processed components of a button battery is the negative electrode cap. The appearance defects of the negative electrode cap mainly include flash, scratches, dents, missing parts of the injection molding, and small gaps. Due to the diversity of defects, most factories still rely on manual visual inspection. Among them, the geometric characteristics of dent defects are random and highly reflective to light. Using a line scan camera to take line-by-line pictures and combine them into a single image provides a better observation effect.

[0003] Currently used detection devices use a ring light source for illumination and a single camera for shooting, resulting in poor imaging of negative electrode cap damage and a low detection rate for negative electrode cap damage. Utility Model Content

The surface light source body is slidably connected to the stand through a light source frame. The line scan camera is located below the surface light source body.

[0006] The light source body is arranged parallel to the line scan camera.

Detailed Implementation

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] As shown in the figure, a detection device for damage to the negative electrode cover using a line scan camera includes a base 2, a stand 1, a line scan camera 10, and a surface light source body 7. The lower end of the stand 1 is slidably and adjustablely connected to the base 2. The line scan camera 10 is slidably connected to the stand 1 via a camera frame. The surface light source body 7 is slidably connected to the stand 1 via a light source frame. The line scan camera 10 is positioned below the surface light source body 7.

[0017] The camera frame includes a first slide 4, a first horizontal plate 8, and a first vertical plate 9. The first slide 4 is slidably connected to the upright frame 1 and adjustable up and down. The right end of the first horizontal plate 8 is fixedly connected to the first slide 4. The left end of the first horizontal plate 8 is provided with a camera parallel keyway 11. The upper end of the first vertical plate 9 is slidably connected in the camera parallel keyway 11. The lower end of the first vertical plate 9 is provided with a camera arc-shaped keyway 12. The line scan camera 10 is slidably connected in the camera arc-shaped keyway 12 through a first limiting member.

[0018] The light source frame includes a second slide 3, a second horizontal plate 5, and a second vertical plate 6. The second slide 3 is slidably connected to the upright frame 1 and adjustable up and down. The left end of the second horizontal plate 5 is fixedly connected to the second slide 3. The right end of the second horizontal plate 5 is provided with a light source parallel keyway 13. The upper end of the second vertical plate 6 is slidably connected in the light source parallel keyway 13. The lower end of the second vertical plate 6 is provided with a light source arc-shaped keyway 14. The surface light source body 7 is slidably connected in the light source arc-shaped keyway 14 through a second limiting member.

[0019] The first slide 4 and the second slide 3 can be locked in place by a locking knob.

[0020] The light source body is arranged parallel to the line scan camera 10. The line scan camera 10 is tilted towards the direction of movement of the negative electrode cover, with an angle of 0-60° between the line scan camera 10 and the vertical direction. The parallel keyway 11 of the camera controls the line scan camera 10 to be adjusted left and right by 0-15cm. This helps to highlight the detailed features of the pressure marks on the surface of the negative electrode cover, avoiding interference from defects such as scratches and dirt. Under the illumination of the surface light source, the image contrast of the pressure mark area is significantly different from that of the adjacent area, resulting in a high imaging effect on the negative electrode cover and effectively avoiding the omission of small and shallow pressure marks.
