Description

Technical Field

[0001] The utility model relates to the technical field of quality control in the battery manufacturing industry, and more specifically, to an optical inspection device for AGM separators. Background Art

[0002] The AGM separator is one of the key components of a sealed lead-acid battery. Its main function is to isolate the positive and negative electrodes of the battery to prevent short circuits, while maintaining the distribution of the electrolyte. The quality of the AGM separator directly affects the performance and service life of the battery. During the production process of the AGM separator, due to factors such as raw materials, production equipment, or production environment, defects such as holes, impurities, and wrinkles may appear on the surface of the separator, which will seriously affect the performance of the battery. Therefore, the detection of surface defects of the AGM separator has become an indispensable part of production.

[0003] Traditional detection of surface defects of AGM separators mainly relies on manual visual inspection. This method is not only inefficient but also may lead to inaccurate and inconsistent detection results due to human factors. With the improvement of the degree of production automation, manual detection can no longer meet the needs of modern production. In addition, the ability of manual detection to identify minor defects is limited, and long-term repetitive detection work is likely to cause visual fatigue of the staff, affecting the detection accuracy.

[0004] In recent years, the development of machine vision detection technology has made it possible to automatically detect surface defects of AGM separators. The machine vision detection system collects images of the object to be detected through a camera and analyzes the images using image processing technology to achieve automatic detection of surface defects of the object. However, there are still some deficiencies in the existing machine vision detection systems when applied to the detection of surface defects of AGM separators:

[0005] 1. Most of the existing optical inspection devices are fixedly arranged and cannot be adjusted according to actual needs;

[0006] 2. When the existing optical inspection device is detecting, floating dust or foreign objects are likely to appear on the AGM separator, affecting the detection results;

[0007] 3. After long-term detection by the existing optical inspection device, dust may fall on the light source, affecting the detection results. Summary of the Utility Model

[0008] Based on the above technical problems, the utility model proposes an optical inspection device for AGM separators.

[0009] An optical inspection device for an AGM separator, comprising an optical inspection box. A detection light source is arranged inside the optical inspection box. A glass plate is arranged on the upper part of the optical inspection box. The AGM separator passes between the glass plate and the detection light source. It further comprises a base. Walking wheels are arranged on the lower side of the base. A support rod is arranged at the center of the base. The optical inspection box is fixed at the upper end of the support rod. Limiting rods are arranged at the four corners of the base and the optical inspection box. The lower ends of the limiting rods are fixed on the base. The upper ends of the limiting rods are slidably installed inside the side walls of the optical inspection box. A dust cleaning device is arranged at the AGM separator inlet of the optical inspection box. A through hole is arranged in the middle of the dust cleaning device. Cleaning brushes are arranged on the upper and lower sides of the through hole. An air duct is arranged on each of the upper and lower sides outside the through hole. The air duct is communicated with a blower through a connecting pipe. The air outlet of the air duct faces the AGM separator to be detected.

[0010] Preferably, the support rod is a hydraulic lifting rod.

[0011] Preferably, the dust cleaning device is also arranged at the AGM separator outlet of the optical inspection box.

[0012] Preferably, a lower air duct is arranged at the bottom of the optical inspection box. The lower air duct is communicated with the optical inspection box. A filter plate is arranged in the middle of the lower air duct. The lower end of the lower air duct is communicated with the blower.

[0013] Beneficial effects:

[0014] 1. The setting of the dust cleaning device ensures the cleanliness of the AGM separator before and after detection, and avoids the influence of dust and impurities on the detection results;

[0015] 2. The hydraulic lifting function of the support rod enables the height of the optical inspection box to be adjustable, meeting the requirements of different production lines;

[0016] 3. The optimized design of the overall structure improves the detection efficiency and the mobility of the device, and reduces the production cost.

[0024] It should be noted that the AGM separator mentioned in this device is a continuous transmission AGM separator belt.

[0025] In order to facilitate passing the AGM separator through the dust cleaning device 8, the upper part of the dust cleaning device 8 can be set as a detachable structure. During installation, the optical inspection box 1 is moved below the AGM separator, and then the height of the optical inspection box 1 is lifted by the support rod 2 so that the AGM separator is located in the through port 9 at the lower part of the dust cleaning device 8.
