Technical Field

[0001] The utility model relates to the technical field of cylindrical battery detection, in particular to a sorting and detecting device for cylindrical batteries. Background Technique

[0002] Cylindrical batteries are batteries with high capacity, long cycle life and wide operating temperature range. They have a wide range of applications and are commonly seen in daily life. When sorting and detecting cylindrical batteries, a sorting and detecting device for cylindrical batteries is required. When performing X-ray detection on cylindrical batteries, the direct test method is generally used, that is, the battery to be tested is placed in front of the X-ray emission source, and after the X-ray irradiates the battery to be tested, it reaches the X-ray detector. Since the positive and negative electrode materials inside the battery are different, the overlapping thickness is different, and the absorption of X-rays is different, the intensity of the X-rays passing through the battery is different. The X-ray detector can draw the internal morphology of the battery to be tested according to the different intensities of the detected X-rays, and then measure the alignment degree of the positive and negative electrodes in the battery.

[0003] Common sorting and detecting devices for cylindrical batteries still have some problems. For example, when detecting batteries, the batteries need to be placed in a suitable position, but it is not convenient to limit cylindrical batteries of different sizes according to requirements, which is likely to affect the detection accuracy.
