Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component surface detection, in particular to a photovoltaic component detection device capable of performing continuous multi-surface detection. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: photovoltaic modules (photovoltaic panels), controllers and inverters. Among them, photovoltaic modules are the main sunlight receiving components, and their surface quality needs to be guaranteed. The most common defects on the light-receiving surface of photovoltaic modules are texture defects, mainly including spots, wheel marks (fingerprints), etc., and the common defects on the mounting surface are misalignment of mounting holes or missing snap-on parts. Therefore, it is necessary to detect the surface defects of photovoltaic modules and distinguish the defect categories, and then perform relevant processing on the photovoltaic modules according to the specific defect type until the production quality requirements are met.

[0003] For the surface defect detection of photovoltaic modules, the surface status is generally recorded by detecting the probe, and then the recorded image is analyzed by analysis and comparison software to determine whether there are surface defects and the type of defects. Since both the light-receiving surface and the installation surface of the photovoltaic module may have surface defects, double-sided detection is required. However, existing detection devices are often only capable of single-sided detection. Therefore, for a single photovoltaic module, it is necessary to perform flip detection after the single-sided detection is completed. The detection process of a single photovoltaic module includes four steps: placement, single-sided detection, flip detection, and removal. This undoubtedly increases the detection process and detection time of a single photovoltaic module, causing the overall detection efficiency to decrease. In addition, the placement, flipping, and removal processes are all non-detection time, which affects the continuity of the entire detection device.

[0004] Therefore, it is necessary to invent a detection device for photovoltaic modules that can be used for continuous multi-faceted detection to solve the above problems. Utility Model Content

[0005] In order to address the deficiencies in the prior art, the purpose of the present utility model is to provide a detection device for photovoltaic modules that can perform continuous multi-sided detection, which solves the problem that the detection device in the prior art can often only detect a single side. Therefore, for a single photovoltaic module, it is necessary to turn over and detect it after the single-sided detection is completed. The detection process of a single photovoltaic module includes four steps: placement, single-sided detection, flip detection and removal. This undoubtedly increases the detection process and detection time of a single photovoltaic module, thereby reducing the overall detection efficiency. In addition, the placement, flipping and removal processes are all non-detection time, thereby affecting the continuity of the entire detection device.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0010] As a preferred solution of the utility model, four slots are opened in the rotating drum, and the four slots are arranged in a circle with equal divisions. The four plug plates can be removably inserted into the slots respectively. Locking plates can be removably sleeved at the positions of both ends of the rotating rod close to the end surface of the rotating drum. One side of the locking plate is connected to multiple locking blocks that can be respectively inserted into the corresponding slots.

[0011] As a preferred solution of the utility model, the plug plate is located on one side wall of the rotating drum and is connected to a guide rail, and the side U-shaped clamp is detachably installed with a slide seat at one end close to the rotating drum, and the corresponding two slide seats can slide synchronously laterally along the corresponding guide rails, and the side U-shaped clamp and the end U-shaped clamp are both detachably embedded with U-shaped rubber pads.

[0014] In the utility model, the two side U-shaped clips on each plug board are driven to slide synchronously, so that the spacing between the two side U-shaped clips is consistent with the width of the photovoltaic module, and then the two side U-shaped clips on the same plug board and the end U-shaped clip can clamp and fix a photovoltaic module. When the detection is performed from left to right, the rotating drum rotates clockwise. At this time, the detection component located on the left side of the bottom surface of the top plate performs a single-sided detection on the photovoltaic module clamped and fixed on the left plug board. The photovoltaic module clamped and fixed in the plug board above the rotating drum has completed the single-sided detection and is in the flip-over waiting position. The detection component located on the right side of the bottom surface of the top plate performs a flip-over detection on the photovoltaic module clamped and fixed on the right plug board. At this time, the single photovoltaic module on the right plug board has passed the single-sided and flip-over detection, and can be removed from the right plug board and can clamp and fix a new photovoltaic module to be detected. Therefore, at this time, the clamped photovoltaic module in the plug board below the rotating drum The fixed photovoltaic module is the new one to be inspected.

A bearing 9 is detachably embedded in the slot. A rotating rod 10 is detachably passed through the rotating cylinder 12, and the rotating rod 10 is rotatably passed through two bearings 9. The locking seat 8 and the cross bar 7 can provide installation positions for the bearing 9, and the bearing 9 can provide a stable and smooth rotation environment for the rotating rod 10.

[0025] An indicating disc 11 is provided at one end of the rotating rod 10 for indicating the rotation angle of the rotating rod 10 . Each rotation of the rotating rod 10 by 90 degrees can be indicated and recorded by the indicating disc 11 , thereby completing the switching and approach of the detection process.

[0026] Four slots 13 are provided in the rotating drum 12, and the four slots 13 are arranged in an equally divided circle. The four plug plates 15 can be removably inserted into the slots 13 respectively. Locking plates 14 can be removably sleeved at the positions of both ends of the rotating rod 10 near the end surface of the rotating drum 12.

[0027] The plug plate 15 is located on one side wall of the rotating drum 12 and is connected to a guide rail 16. A side U-shaped clamp 18 is detachably mounted with a slide 17 at one end close to the rotating drum 12.
