Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel production equipment, specifically to a quality inspection device for photovoltaic panels. Background Technology

[0002] After the photovoltaic panels are manufactured, they should undergo quality inspection, mainly by using impact testing devices to detect potential damage to the photovoltaic panels in order to assess their service life.

[0003] For example, CN 221728299 U discloses a quality inspection device for photovoltaic panels, which includes a support plate with a limiting mechanism for restricting the photovoltaic panel's position; an arc-shaped conduit is fixedly mounted on the support plate via a mounting bracket, and a speed sensor is located at the end of the arc-shaped conduit; the interior of the arc-shaped conduit is equipped with an impact mechanism to reduce secondary impacts. This device aims to reduce the phenomenon of rebound and re-impact after an initial impact, thereby increasing the accuracy of the inspection results. However, the following problems still exist: 1. The impact point is fixed, and the impact position cannot be flexibly adjusted, resulting in poor representativeness of the test; 2. It is not conducive to removing the impact ball, affecting the inspection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quality inspection device for photovoltaic panels that has a reasonable structure and reliable operation, solves the above-mentioned problems, has high inspection efficiency, improves the representativeness of the inspection, and effectively improves the inspection accuracy.

[0005] The technical solution of this utility model is:

[0006] A quality inspection device for photovoltaic panels includes a base plate and a limiting plate disposed on the base plate. The key technical features are: the limiting plate is a right-angled plate; positioning components are provided on the X-direction side plate of the right-angled plate corresponding to the four corners of the photovoltaic panel; a Z-direction linear module is provided on the Y-direction plate of the right-angled plate; an X-direction linear module is fixed to the slider of the Z-direction linear module; a ball-laying guide tube is fixed to the slider of the X-direction linear module; the tail end of the ball-laying guide tube faces the X-direction side plate; a speed sensor is fixed to the top of the tail section of the ball-laying guide tube; a slidable base plate is provided on the bottom surface of the tail section of the ball-laying guide tube; a driving component connected to the slidable base plate is fixed to the side of the ball-laying guide tube; and a proximity switch is fixed to the other side of the ball-laying guide tube.

[0007] The aforementioned quality inspection device for photovoltaic panels includes a ball-releasing conduit consisting of a vertical section, a horizontal section, and a transition section connecting the vertical and horizontal sections. The lower end of the horizontal section is provided with a U-shaped guide plate that communicates with the bottom opening of the sliding base plate. The lower end of the U-shaped guide plate is provided with a ball-receiving hopper. The upper side of the vertical section of the ball-releasing conduit is provided with a ball-releasing port.

[0008] The aforementioned quality inspection device for photovoltaic panels includes a positioning component consisting of four right-angle positioning plates, positioning bolts threaded onto the right-angle positioning plates, and positioning pads located at the tips of the positioning bolts. The positioning pads are used to press down on the photovoltaic panels.

[0009] In the aforementioned quality inspection device for photovoltaic panels, the driving component is an electric push rod, the sliding base plate is a right-angle plate, the outer end of the right-angle plate is connected and fixed to the end of the telescopic rod of the electric push rod, and the outer side of the ball-releasing guide tube is provided with an extended guide groove corresponding to the sliding base plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. The longitudinal position of the ball-laying guide tube can be adjusted by the Z-axis linear module, and the horizontal position of the ball-laying guide tube can be adjusted by the X-axis linear module, thereby achieving the purpose of adjusting the end of the ball-laying tube, flexibly changing the impact point position on the photovoltaic panel, improving the representativeness of the test, and thus effectively improving the test accuracy.

[0012] 2. During the process of the impact ball impacting the photovoltaic panel through the end of the ball release tube, it passes through a proximity switch in advance. After the proximity switch provides a feedback signal, the drive component moves the sliding base plate. After the impact ball bounces, it falls out of the ball release tube, making it easy for staff to retrieve the ball for re-inspection, which significantly improves the inspection efficiency.

[0017] The present invention will be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-3As shown, the quality inspection device for the photovoltaic power generation panel includes a base plate 10 and a limiting plate 1 disposed on the base plate 10. The limiting plate 1 is a right-angle plate.

[0019] In this embodiment, the X-direction side plate 101 of the right-angled upright plate is provided with positioning components at the four corners of the photovoltaic power generation panel 2. The positioning components consist of four right-angled positioning plates 4, positioning bolts 3 threadedly connected to the right-angled positioning plates 4, and positioning pads 14 located at the tips of the positioning bolts 3. The positioning pads 14 are used to press down on the photovoltaic power generation panel 2.

[0020] The right-angled upright plate 102 is provided with a Z-direction linear module 6. An X-direction linear module 5 is fixed on the slider of the Z-direction linear module 6. A ball-releasing guide tube 7 is fixed on the slider of the X-direction linear module 5. The tail end of the ball-releasing guide tube 7 faces the X-direction side plate 101.

[0021] A speed sensor 12 is fixed to the top of the horizontal section of the ball-releasing conduit 7. A slidable base plate 13 is provided on the bottom surface of the horizontal section of the ball-releasing conduit 7. A drive assembly connected to the slidable base plate 13 is fixed to the side of the horizontal section of the ball-releasing conduit 7. A proximity switch 15 is fixed to the other side of the horizontal section of the ball-releasing conduit 7. The drive assembly is an electric push rod 17. The slidable base plate 13 is a right-angle plate. The outer end of the right-angle plate is connected and fixed to the end of the telescopic rod of the electric push rod 17. The ball-releasing conduit 7 has an extended guide groove 16 corresponding to the slidable base plate 13 on its exterior. In this embodiment, the ball-releasing conduit 7 consists of a vertical section, a horizontal section, and a transition section connecting the vertical section and the horizontal section. A U-shaped guide plate 8 communicating with the bottom opening of the slidable base plate 13 is provided below the tail section of the horizontal section. A ball-receiving hopper 9 is provided at the lower end of the U-shaped guide plate 8. A ball-releasing port is provided on the side of the upper end of the vertical section of the ball-releasing conduit 7.

[0022] Working principle:

[0023] 1. The position of the ball-laying guide tube 7 is adjusted in advance by using the Z-direction linear module 6 and the X-direction linear module 5, thereby adjusting the impact position of the impact ball 11 on the photovoltaic panel 2.

[0024] 2. The impact ball 11 is placed into the ball release port. The impact ball 11 moves quickly towards the photovoltaic panel 2 through the vertical section, transition section and horizontal section of the ball release guide tube 7. When it approaches the tail port, the speed sensor 12 detects the moving speed of the impact ball 11. At the same time, when it passes the proximity switch 15, the proximity switch 15 sends a feedback signal. The electric push rod 17 pushes the sliding base plate 13 outward after a delay. After the impact ball 11 rebounds, it falls out of the ball release guide tube 7 and falls into the ball receiving bucket 9 through the U-shaped guide plate 8, which is convenient for the staff to take out and carry out the next operation.

[0025] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
