Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel testing technology, and in particular to a photovoltaic panel surface testing device. Background Technology

[0002] A photovoltaic panel is an assembly consisting of several solar cell modules assembled on a single plate in a specific manner. It is typically used as a unit in a photovoltaic array. To ensure the quality of photovoltaic panels, surface defect detection is required.

[0003] In existing technologies, such as the online defect detection device for photovoltaic panels disclosed in patent application number "CN201520139881.5", the process flow suffers from significant efficiency bottlenecks. This device employs a traditional single-piece flow inspection mode, requiring operators to manually place each photovoltaic panel one by one at the conveyor belt input end. After inspection, each panel is then removed from the output end and re-stacked. This discrete loading and unloading method not only prolongs the production cycle time but also increases the frequency of manual intervention, severely limiting the theoretical capacity of the inspection system. Especially when handling large-size photovoltaic panels, frequent handling increases the risk of breakage and can affect inspection accuracy due to potential deviations in manual placement. Furthermore, this design fails to achieve seamless integration between the inspection process and the front-end and back-end production lines, resulting in insufficient overall automation and making it difficult to meet the high-throughput process requirements of modern photovoltaic manufacturing.

[0004] To address the aforementioned problems, this utility model proposes a photovoltaic panel surface inspection device. Utility Model Content

[0023] Please see Figure 1-3 This utility model provides a technical solution: a photovoltaic panel surface inspection device, including an inspection platform 1, which is arc-shaped. The upper end face of the inspection platform 1 has three rectangular holes 2 at equal intervals around the axis of the inspection platform 1. The lower end face of the inspection platform 1 is fixedly installed with a fixing box 3 at the position corresponding to the three rectangular holes 2.

A rectangular frame 7 is fixedly installed at the end of the connecting plate 6 away from the motor 5. The rectangular frame 7 is correspondingly positioned above the rectangular holes 2.

[0024] Electric push rods 8 are fixedly installed at the bottom of the internal part of the fixed box 3. Base plates 9 are fixedly installed on the telescopic ends of the electric push rods 8. The lower end face of the support plate 4 is engaged with the upper end face of the base plate 9. Insertion arm slots 10 are provided on both sides of the upper end face of the base plate 9.

[0025] In this embodiment of the invention: A groove 13 is provided between each of two adjacent rectangular holes 2 on the upper surface of the testing platform 1. Multiple guide tubes 14 are rotatably installed inside each groove 13. This facilitates the conduction of light between the photovoltaic panel and the two rectangular holes 2, reduces friction, and prevents damage to the photovoltaic panel's base plate.

[0028] It should be noted that a travel limit switch is provided on the positioning plate 18. When the rectangular frame 7 contacts the positioning plate 18, the travel limit switch can control the motor 5 to reverse and return to the initial position.

[0029] All the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0030] Working principle:

[0031] First, a forklift is used to transfer the support plate 4 and the stacked photovoltaic panels to the fixed box 3 in the middle position and place it on the base plate 9. Then, the corresponding electric push rod 8 extends to drive the photovoltaic panel to rise, so that the bottom surface of the top photovoltaic panel rises to the same height as the top surface of the testing table 1, so that the rectangular frame 7 is fitted on the outside of the top photovoltaic panel. At this time, the upper surfaces of the support plates 4 on both sides are raised to a position that is one photovoltaic panel thickness away from the top surface of the testing table 1 by the support of the corresponding electric push rod 8.

[0032] At this time, the inspection camera 16 performs surface defect inspection on the top photovoltaic panel. If the photovoltaic panel has no defects, the motor 5 starts, driving the connecting plate 6 to rotate clockwise. The connecting plate 6 drives the rectangular frame 7 to rotate synchronously, causing the rectangular frame 7 to move the photovoltaic panel. When the rectangular frame 7 contacts the left positioning plate 18, the photovoltaic panel has moved into the left rectangular hole 2 and lands on the left support plate 4. The left electric push rod 8 retracts, causing the left support plate 4 to move downward by the thickness of one photovoltaic panel, making it easier to receive the next photovoltaic panel. At this time, the motor 5 reverses, driving the connecting plate 6 to rotate counterclockwise, causing the rectangular frame 7 to return to its original position. After the rectangular frame 7 returns to its original position, the electric push rod 8 in the middle position extends, causing the photovoltaic panel to rise, and then perform the next inspection.

[0033] If there are defects on the surface of the photovoltaic panel, the motor 5 starts and drives the connecting plate 6 to rotate counterclockwise. The connecting plate 6 drives the rectangular frame 7 to rotate synchronously, so that the rectangular frame 7 moves the photovoltaic panel. When the rectangular frame 7 contacts the right positioning plate 18, the photovoltaic panel has moved into the right rectangular hole 2 and falls on the right support plate 4. The right electric push rod 8 retracts and drives the left support plate 4 to move down by the thickness of one photovoltaic panel, so as to support the next photovoltaic panel.

[0034] When a large number of photovoltaic panels are collected in the fixed boxes 3 on both sides, a forklift is used to extend into the insert arm slot 10 to lift the support plate 4 and the accumulated photovoltaic panels and transfer them to the storage location.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
