Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel production, in particular to a photovoltaic component appearance inspection lighting component. Background Art

[0002] Photovoltaic modules, also known as solar panels, can convert solar energy into electrical energy. They are composed of photovoltaic glass, EVA film, battery cells, EVA film, and backplane laid from top to bottom. The stacked modules need to be evacuated, and then heated to melt the EVA film, so that the photovoltaic glass, battery cells, and backplane are bonded together. After the photovoltaic module is prepared, the appearance of the glass surface needs to be manually inspected. The existing inspection method is to flip the photovoltaic module 90° to expose its glass surface, then use light to illuminate it, and inspect its appearance through naked eye observation by workers.

[0003] Since photovoltaic modules are large in size and difficult to flip manually, the prior art uses an appearance inspection flipping machine to flip them over and then illuminate the glass surface with light. The light of the traditional appearance inspection flipping machine is fixed on the ceiling and illuminates diagonally downward. This method has the following disadvantages: (1) In the 90° flipped state, the upper part of the photovoltaic module is illuminated by strong light, while the lower part is illuminated by very weak light, making the lower part difficult to observe; (2) The lighting direction is fixed, but some defects on the glass are difficult to observe at one lighting angle. Workers often need to walk back and forth to change the light reflection angle and carefully identify the surface of the glass, which is not very convenient for observation.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art, thereby providing a photovoltaic module appearance inspection lighting component which has a scientific design, no blind spots in lighting, convenient observation, and strong practicality.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a photovoltaic module appearance inspection lighting assembly, including an inspection table and two vertical lamp stands, a flipping mechanism for flipping the photovoltaic module 90° is arranged in the center of the rear part of the inspection table, and the two vertical lamp stands stand on both sides of the front part of the inspection table, each of the vertical lamp stands includes a driving motor, a rotating lamp holder installed on the inspection table and a lamp tube assembly vertically installed on the rotating lamp holder, the rotating shaft of the rotating lamp holder is vertically arranged, the driving motor drives the rotating lamp holder to rotate, and a number of vertical shading strips are evenly spaced on the lamp tube assembly to allow the light to intermittently sweep across the inspection area above the inspection table.

[0007] Based on the above, the lamp tube assembly includes a central lamp tube and three vertical shading strips arranged around the central lamp tube, and the angles between the two side edges of the vertical shading strips and the center of the central lamp tube are 30-45 degrees.

[0008] Based on the above, the rotating lamp holder is externally connected to a power line via a conductive slip ring.

[0009] Based on the above, a reflective baffle is provided on the inspection table corresponding to each of the vertical lamp stands, and the reflective baffle surrounds the outer corner direction of the vertical lamp stand.

[0010] Based on the above, a ceiling is also provided directly above the inspection table, and the top end of the vertical lamp rack is rotatably mounted on the ceiling.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model arranges two vertical lamp racks on both sides of the front of the inspection table to illuminate the flipped photovoltaic module from both sides, so that the light intensity at various places on the surface of the photovoltaic module is more uniform. At the same time, the rotating lamp holder can drive the lamp tube assembly to rotate, and a number of vertical shading strips will block part of the light, so that the light on both sides can intermittently sweep across the inspection area. The staff can see the light from multiple angles sweeping across the glass surface without walking back and forth, which is convenient for the staff to observe. It has the advantages of scientific design, no blind spots in lighting, convenient observation and strong practicality.

[0012] Furthermore, the setting of the reflective baffle can, on the one hand, reflect the light toward the detection area to increase the brightness of the detection area, and on the other hand, avoid the bright light on both sides from distracting vision, making it easier to observe; the top end of the vertical lamp stand is rotatably installed on the ceiling, so that the rotation of the vertical lamp stand can be more stable.

The above-mentioned equipment is a commonly used appearance inspection flipping machine in this field, and no creative labor is required to obtain it.

[0018] In order to ensure that all parts of the surface of the photovoltaic component 3 can be illuminated by strong light, two vertical lamp stands are erected on both sides of the front of the inspection table 1, and each of the vertical lamp stands includes a driving motor 5, a rotating lamp holder 6 installed on the inspection table 1, and a lamp tube assembly 7 vertically installed on the rotating lamp holder 6. The lamp tube assembly 7 can illuminate the photovoltaic component 3 from both sides, so that the light intensity at various parts of the surface of the photovoltaic component 3 is more uniform.

[0019] In order to make observation more convenient, the rotating shaft of the rotating lamp holder 6 is arranged vertically, and the driving motor 5 drives the rotating lamp holder 6 to rotate.

[0020] In order to further improve the brightness of the detection area, a reflective baffle 8 is provided on the inspection table 1 corresponding to each of the vertical lamp stands. The reflective baffle 8 surrounds the outer corner direction of the vertical lamp stand. On the one hand, it can reflect the light toward the detection area, and on the other hand, it can avoid the bright light on both sides from distracting vision, making it easier to observe.

Specifically, a shaft sleeve can be installed on the ceiling 2, and a rotating seat is set at the top end of the vertical lamp stand, and the rotating seat is installed in the shaft sleeve.
