Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-3 It can be known that the utility model provides a kind of technical scheme: a photovoltaic sheet PL detection equipment, comprising: device main body 1, display 2, conveyor 3, fixed frame 4, laser head 5 and linear array camera 6, the top of device main body 1 is separately installed with display 2, conveyor 3 and fixed frame 4, one side of fixed frame 4 is installed with laser head 5, the other side of fixed frame 4 is provided with linear array camera 6, linear array camera 6 is installed with connecting plate 7 close to one side of fixed frame 4, the top of fixed frame 4 is welded with fixed seat 8, fixed seat 8 is connected with lead screw 9 in the inside by bearing, the outside of lead screw 9 is welded with first bevel gear 10, the outside of lead screw 9 is threadedly connected with moving block 11, moving block 11 is connected by bolt between connecting plate 7, the outside of fixed seat 8 is connected with fixed block 12, the inside of fixed block 12 is rotatably connected with rotating block 13, the end of two rotating blocks 13 is commonly connected with connecting cylinder 14, connecting cylinder 14 is connected with rotating rod 15 close to one side of fixed seat 8, the outside of rotating rod 15 is welded with second bevel gear 16, rotating structure is formed between rotating rod 15 and fixed block 12, meshing structure is formed between second bevel gear 16 and first bevel gear 10, sliding structure is formed between moving block 11 and fixed seat 8.

[0021] In specific implementation, the photovoltaic sheet PL detection device is an important device indispensable in the photovoltaic industry. The traditional linear array camera 6 position adjustment mode is more troublesome and time-consuming. When the photovoltaic sheet size is large, the position of the linear array camera 6 needs to be adjusted. The connecting cylinder 14 can be reversed. When the connecting cylinder 14 is reversed, the rotating block 13 and the rotating rod 15 can be rotated. When the rotating block 13 rotates, it can rotate inside the fixed block 12. When the rotating rod 15 rotates, it can drive the second bevel gear 16 to rotate. When the second bevel gear 16 rotates, it can mesh to drive the first bevel gear 10 to rotate. When the first bevel gear 10 rotates, it can drive the lead screw 9 to rotate. When the lead screw 9 rotates, it can drive the moving block 11 to threadedly slide away from the fixed frame 4. When the fixed frame 4 moves, it can drive the connecting plate 7 to move. When the connecting plate 7 moves, it can drive the linear array camera 6 to move. When the linear array camera 6 moves to the appropriate position, the rotation of the connecting cylinder 14 can be stopped. At this time, the position of the linear array camera 6 can capture complete and clear light-emitting images. Conversely, when the photovoltaic sheet size is small, the connecting cylinder 14 can be positively rotated, so that the position of the linear array camera 6 can be lowered to an appropriate height.

[0022] Referring to Figures 1-3 It can be seen that by rotating the connecting cylinder 14, the position of the linear array camera 6 can be quickly and simply adjusted. After the position of the linear array camera 6 is adjusted, the detection operation can be immediately performed.

[0023] Referring to Figure 1 and Figure 4 It can be seen that the outer side of the device body 1 is provided with a support frame 17. The surface of the support frame 17 is provided with a connecting block 18. The inside of the connecting block 18 is slidably connected with a sliding block 19. The top of the sliding block 19 is provided with a sliding groove 20. The top of the connecting block 18 is threadedly connected with a threaded knob 21. The surface of the support frame 17 close to the connecting block 18 is connected with a connecting seat 22. The inside of the connecting seat 22 is penetratedly connected with a guide rod 23. The guide rod 23 and the end of the sliding block 19 are jointly connected with a limiting plate 24. The threaded knob 21 and the sliding block 19 constitute a sliding structure through the sliding groove 20.

[0024] In specific implementation, when the photovoltaic sheet detection is completed, the photovoltaic sheet can be conveyed to the next process by the conveyor 3. In this process, the conveyor 3 on the equipment main body 1 is usually docked with another set of conveyors 3 in the next process, which is not shown in the figure, so as to complete the conveying of the photovoltaic sheet. Since there is a gap between the two sets of conveyors 3, the photovoltaic sheet is prone to position deviation and falling when moving between the two sets of conveyors 3. The two sets of sliding blocks 19 can be pushed according to the size of the photovoltaic sheet. When the size of the photovoltaic sheet is large, the two sets of sliding blocks 19 can be pulled away from each other. When the sliding block 19 moves, it can slide with the connecting block 18. When the sliding block 19 slides, it can drive the limiting plate 24 to move. When the limiting plate 24 moves to the specified position, the threaded knob 21 can be tightened. When the threaded knob 21 is tightened, the end portion thereof can extrude and fix the sliding block 19 through the sliding groove 20, so that the position of the limiting plate 24 is not prone to loosening.

[0025] Referring to Figure 1 and Figure 4 It can be known that the two sets of limiting plates 24 can assist in guiding the photovoltaic sheet, so that the photovoltaic sheet is not prone to position deviation and falling when moving from one set of conveyors 3 to another set of conveyors 3.

[0026] In summary, when the photovoltaic sheet PL detection equipment is used, the connecting barrel 14 can be reversed. When the connecting barrel 14 is reversed, the rotating block 13 and the rotating rod 15 can be driven to rotate. When the rotating block 13 rotates, it can rotate inside the fixed block 12. By rotating the connecting barrel 14, the position of the linear array camera 6 can be quickly and simply adjusted. After the position of the linear array camera 6 is adjusted, the detection work can be immediately performed. When the threaded knob 21 is tightened, the end portion thereof can extrude and fix the sliding block 19 through the sliding groove 20, so that the position of the limiting plate 24 is not prone to loosening. The two sets of limiting plates 24 can assist in guiding the photovoltaic sheet, so that the photovoltaic sheet is not prone to position deviation and falling when moving from one set of conveyors 3 to another set of conveyors 3. The contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0027] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
