Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module manufacturing equipment, and in particular relates to a photovoltaic module appearance inspection device. Background Technology

[0002] See Figure 1 The photovoltaic module 10 consists of a solar panel 11, a frame 12, and an electrical connector group 13. The electrical connector group 13 is generally located in the middle or end of the photovoltaic module 10 along its length. Figure 1 The first electrical connector 131, the second electrical connector 132, and the third electrical connector 133 are arranged in a wide direction to output the electricity generated by the photovoltaic module 10. The solar panel 11 is composed of battery cells connected in series and in parallel. After the electrical connector group 13 is welded to the solar panel 11 and after the frame 12 is installed, online appearance inspection is required to reject defective products such as dimensional deviation, missing corners, chipped edges, battery cell misalignment, busbar misalignment, and dirt.

[0003] Before being framed, photovoltaic modules have relatively poor overall rigidity during photography, making them prone to image distortion. The large size of photovoltaic modules also places high demands on camera field of view and light source, creating stringent requirements for the overall photographic environment and making image glare susceptible to occur. Image distortion and image glare affect the consistency and accuracy of test results.

[0004] Existing technology uses a field-array camera to take pictures of the front and back of the solar panel 11 of a photovoltaic module. Due to the limited field of view of the field-array camera, for large-sized photovoltaic modules, it is necessary to take pictures of different parts each time and then stitch the pictures of the multiple parts together to capture the complete photovoltaic module. Since the positioning requirements for multiple pictures are high, the intelligence requirements for the stitching algorithm are also high. Often, some uncontrollable variables in the intermediate links will cause stitching errors, resulting in distortion of the module image.

[0005] To overcome the impact of image distortion, image spotting, and image falsification on inspection results, we developed a photovoltaic module appearance inspection device. This device uses an 8K line scan camera to scan the photovoltaic module and uses image recognition to detect defects such as dimensional deviations, missing corners, chipped edges, cell misalignment, busbar misalignment, and dirt in the photovoltaic module 10, allowing us to reject defective products.
