Description

TECHNICAL FIELD

[0001] The utility model relates to battery manufacturing technical field especially relates to battery substrate detection equipment. BACKGROUND

[0002] Solar power generation is a kind of power generation mode that can directly convert solar energy into electric energy, and is a kind of renewable clean energy. Solar power generation is paid more and more attention due to its simple utilization, safety, non-pollution and the characteristics of being available at any place. Due to the wide distribution of solar spectrum, single-junction solar cells can only absorb photons with higher energy than the band gap, so the efficiency of converting light energy into effective electric energy is low. Perovskite solar cells become a feasible option for preparing high-efficiency solar cells due to their adjustable band gap, simple preparation process, low cost and many other advantages.

[0003] In the related art, the detection method for perovskite solar cell substrate is electroluminescence, and the basic principle is luminescence imaging. The sample surface is excited to emit light, and then a camera is used to capture the imaging of the light emission. Electroluminescence needs upper and lower electrodes to detect, and cannot detect defects of perovskite solar cell substrate in time and effectively. In the prior art, in order to improve the detection accuracy, an optical detection AOI (Automated Optical Inspection) device is developed, which detects the surface of the battery substrate through a high-magnification camera, and the defects on the surface of the battery substrate can be observed intuitively according to the photographed pictures. In the actual working process, the battery substrate is placed on the assembly line, and the assembly line drives the battery substrate to move to the shooting position of the AIO detection device for detection. However, the conventional AOI detection device cannot accurately position the battery substrate on the assembly line, and the battery substrate cannot be accurately parked at the shooting position, so that the high-magnification camera cannot accurately shoot the battery substrate, and the specific position of the battery substrate needs to be adjusted repeatedly by the staff, which greatly reduces the detection efficiency and detection effect of the battery substrate.

In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0056] In the related art, the detection method for perovskite solar cell substrate is electroluminescence, and the basic principle is luminescence imaging. The sample surface is excited to emit light, and then a camera is used to capture the imaging of the light emission. Electroluminescence needs upper and lower electrodes to detect, and cannot detect defects of perovskite solar cell substrate in time and effectively. In the prior art, in order to improve the detection accuracy, an optical detection AOI (Automated Optical Inspection) device is developed, which detects the surface of the battery substrate through a high magnification camera, and the defects on the surface of the battery substrate can be observed intuitively according to the photographed pictures. In the actual working process, the battery substrate is placed on the assembly line, and the assembly line drives the battery substrate to move to the shooting position of the AIO detection device for detection. However, the conventional AOI detection device cannot accurately position the battery substrate on the assembly line, and the battery substrate cannot be accurately parked at the shooting position, so that the high magnification camera cannot accurately shoot the battery substrate, and the specific position of the battery substrate needs to be adjusted repeatedly by the staff, which greatly reduces the detection efficiency and detection effect of the battery substrate.

[0057] In order to solve the above problems, as shown in Figure 1 and Figure 2 The battery substrate detection device 1000 is used for detecting the battery substrate 3000 conveyed by the conveying device 2000 along the first direction.

[0058] The battery substrate detection equipment 1000 can realize the blocking of the movement of the battery substrate 3000 in the first direction by setting the stop device 300 and abutting the battery substrate 3000 in the first direction, and can realize the positioning and fixing of the battery substrate 3000 by setting the locking device 200 to lock and fix the battery substrate 3000 abutting the stop device 300. The detection structure is set to shoot the battery substrate 3000 and detect the surface quality of the battery substrate 3000 according to the shooting image, so as to realize the accurate detection of the surface quality of the battery substrate 3000. The detection structure is connected with the three-axis driving device 100, and the three-axis driving device 100 drives the detection structure to move arbitrarily in space, so as to adjust the relative position of the detection structure and the battery substrate 3000 in space.

The detection device can detect the surface quality of the battery substrate 3000 according to the shooting image of the shooting device.

[0060] It should be noted that in the embodiment, the detection device includes an image recognition system and an AI (Artificial Intelligence) technology. The image recognition system is mainly an industrial system for detecting and judging images by machines instead of manual work.

In the process of comparing the image shot by the shooting device with the standard image in the resource library by the image recognition system, the AI technology continuously learns and supplements the resource library. When there is no standard comparison image in the resource library, the AI technology can be applied to decompose and learn the existing standard image in the resource library to find the closest standard image, finally give a judgment result and upload the bad related image to the resource library. The resource library is continuously automatically supplemented by the AI technology, so as to improve the detection accuracy and preparedness.
