Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel production technology, and in particular relates to a testing device for photovoltaic panel production. Background Technology

[0002] With the global emphasis on renewable energy and the acceleration of energy transition, the solar photovoltaic industry has developed rapidly. Photovoltaic panels are the core component of a solar power generation system and also the most valuable part of the system. Their function is to convert solar energy into electrical energy, which can then be stored in batteries or used to power loads.

[0003] In the production of photovoltaic (PV) panels, inspection is necessary to ensure their quality and photoelectric conversion efficiency. This inspection typically includes surface inspection and functional testing. Surface inspection primarily aims to detect defects on the PV panel surface, such as spots, chips, and cracks. Current surface inspection methods usually involve capturing images of the panel surface with a camera and comparing the captured images with preset images. While this method can perform some inspection, it lacks effective detection of the edges and sides, easily overlooking issues like cracks at the edges, which can lead to damage during later framing. Therefore, there is an urgent need to research and develop an inspection device for PV panel production to address these problems. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figures 1-2As shown, the present invention is a testing device for photovoltaic panel production, including a horizontally arranged base 1 and a camera 2 disposed above the base 1; the camera 2 is a conventional component in the art; a rotating mechanism 3 for mounting the photovoltaic panel is vertically mounted on the upper surface of the base 1, and the rotating mechanism 3 is capable of horizontally rotating the photovoltaic panel; a push-pull mechanism 4 is horizontally mounted on one side of the rotating mechanism 3; a shifting mechanism 5 for mounting the camera 2 is connected to the push-pull mechanism 4, and the push-pull mechanism 4 is used to adjust the distance between the camera 2 and the photovoltaic panel; the shifting mechanism 5 can drive the camera 2 to move linearly along the length direction of any side of the photovoltaic panel, and the camera 2 is disposed on the side of the photovoltaic panel. In use, the rotating mechanism 3 drives the photovoltaic panel to rotate intermittently horizontally, and the push-pull mechanism 4 adjusts the distance between the camera 2 and the photovoltaic panel. Then, the shifting mechanism 5 drives the camera 2 to move linearly along the length of the corresponding side of the photovoltaic panel. At the same time, the camera 2 continuously captures images of that side of the photovoltaic panel. The upper computer then compares the captured images with preset images, thereby realizing the detection of the side of the photovoltaic panel. This not only effectively improves the detection effect of the photovoltaic panel and avoids the existence of blind spots, but also ensures the production quality of the photovoltaic panel.

[0033] Example 2:

[0034] Based on Example 1, as follows Figures 3-4As shown, the rotating mechanism 3 includes a hollow shaft 303 vertically rotatably connected to the base 1; a conventional negative pressure connector 308 is rotatably connected to the lower end of the hollow shaft 303; a suction pipe 309 is connected to the negative pressure connector 308; a support plate 310 for mounting photovoltaic panels is horizontally bolted to the upper end of the hollow shaft 303; the interior of the support plate 310 has a cavity communicating with the hollow shaft 303, and a plurality of negative pressure holes 311 communicating with the cavity are evenly distributed on the top surface of the support plate 310; a servo motor 301 is provided on one side of the hollow shaft 303; the servo motor 301 is vertically bolted to the base 1. On the lower surface of the base 1, the output shaft of the servo motor 301 passes through the base 1 and is keyed to a first pulley 304; the first pulley 304 is connected to a second pulley 305 via a synchronous belt drive; the second pulley 305 is keyed to the outer periphery of a first rotating shaft 302; the first rotating shaft 302 is vertically rotatably connected to the base 1; the upper end of the first rotating shaft 302 is keyed to a first incomplete gear 306; a first gear 307 is horizontally arranged on one side of the first incomplete gear 306; the first gear 307 is keyed to the outer periphery of the hollow shaft 303; the first gear 307 can mesh with the first incomplete gear 306. In use, the photovoltaic panel is placed horizontally on the support plate 310, with the support plate 310 positioned in the center of the photovoltaic panel. The suction pipe 309, via the negative pressure connector 308 and the hollow shaft 303, draws the interior of the support plate 310 into a negative pressure state, causing the negative pressure hole 311 to suck up the back of the photovoltaic panel. Then, the servo motor 301 drives the first rotating shaft 302 to rotate via the first pulley 304 and the second pulley 305. This causes the first rotating shaft 302 to drive the first incomplete gear 306 to rotate horizontally. When the first incomplete gear 306 meshes with the first gear 307, the first gear 307 drives the hollow shaft 303 to rotate, causing the hollow shaft 303 to drive the photovoltaic panel to rotate horizontally via the support plate 310. When the first incomplete gear 306 disengages from the first gear 307, the photovoltaic panel has rotated exactly 90°, thus achieving the switching of the photovoltaic panel's sides. This allows for the individual detection of all four sides of the photovoltaic panel, effectively ensuring the detection effect of the photovoltaic panel.

[0035] Example 3:

[0036] Based on Example 2, as follows Figures 3-8 As shown, the push-pull mechanism 4 includes a first slide rail 401 horizontally bolted to the upper surface of the base 1; a first slider 402 slidably connected to the first slide rail 401; a first support column 403 vertically bolted to the upper surface of the first slider 402; a mounting block 404 bolted to the first support column 403; a bracket 405 for mounting the displacement mechanism 5 is horizontally arranged on the side of the mounting block 404 near the hollow shaft 303; the bracket 405 is... The structure includes a bracket 405 with a pair of connecting rods 406 parallel to the first slide rail 401 bolted side-by-side in the middle; the ends of the two connecting rods 406 away from the bracket 405 are bolted to the mounting block 404; a cylindrical cam 407 parallel to the first slide rail 401 is provided on the side of the bracket 405 away from the mounting block 404; both ends of the cylindrical cam 407 are rotatably connected to first support blocks 408; both first support blocks 408 are bolted to the upper surface of the base 1. A movable column 409 is vertically slidably inserted into the working groove of the cylindrical cam 407; a push-pull rod 410 is horizontally bolted to the upper end of the movable column 409; the end of the push-pull rod 410 away from the movable column 409 is bolted to the middle of the bracket 405; a first bevel gear 411 is keyed to the end of the cylindrical cam 407 away from the first slide rail 401; a second bevel gear 412 meshes with the first bevel gear 411; the second bevel gear 412 is keyed to the outer periphery of the hollow shaft 303. In use, the hollow shaft 303 drives the cylindrical cam 407 to rotate via the second bevel gear 412 and the first bevel gear 411. When the short side of the photovoltaic panel needs to be parallel to the length direction of the bracket 405, the cylindrical cam 407 drives the bracket 405 to move closer to the hollow shaft 303 via the movable column 409 and the push-pull rod 410. After the photovoltaic panel rotates horizontally by 90°, the short side of the photovoltaic panel is exactly parallel to the length direction of the bracket 405, and at this time the distance between the short side of the panel and the bracket 405 is the shortest. This ensures that the distance between the camera 2 and the photovoltaic panel meets the requirements of the camera 2 for capturing images of the side of the photovoltaic panel. At the same time, when the long side of the photovoltaic panel needs to be parallel to the length direction of the bracket 405, the cylindrical cam 407 drives the bracket 405 away from the hollow shaft 303 via the movable column 409 and the push-pull rod 410. When the photovoltaic panel rotates horizontally by 90°, the long side of the photovoltaic panel is just parallel to the length direction of the bracket 405, and at this time the distance between the long side of the panel and the bracket 405 is the shortest.

[0037] Example 4:

[0038] Based on Example 3, as follows Figures 5-8As shown, the displacement mechanism 5 includes a second slide rail 501 horizontally bolted to the upper surface of the base 1 and a support strip 502 horizontally disposed above the bearing plate 310; both the second slide rail 501 and the support strip 502 are parallel to the first slide rail 401, and the second slide rail 501 is disposed on the side of the hollow shaft 303 away from the first slide rail 401; a second slider 503 is slidably connected to the second slide rail 501; a second support column 504 is vertically bolted to the upper surface of the second slider 503; the upper end of the second support column 504 is bolted to one end of the support strip 502; the other end of the support strip 502 is bolted to the upper end of the first support column 403; the support strip 502 is vertically bolted to the other end of the support strip 502. A second rotating shaft 505 is rotatably connected to the support plate 502, and a conventional elastic telescopic rod 506 is horizontally arranged below the support plate 502. The elastic telescopic rod 506 consists of a rod cylinder, a tension spring connected inside the rod cylinder, and a support rod slidably inserted into the rod cylinder and connected to the tension spring. One end of the elastic telescopic rod 506 is bolted to the lower end of the second rotating shaft 505. The other end of the elastic telescopic rod 506 is rotatably connected to a transmission block 507. A pair of guide rods 508 perpendicular to the support plate 502 are horizontally slidably inserted into the transmission block 507. Both guide rods 508 are bolted to the two side arms of the bracket 405. There are two cameras 2, and the two cameras 2 are obliquely bolted to the transmission block 405. On the side of block 507 near hollow shaft 303; the camera end of one camera 2 is tilted downwards to capture the upper side of the photovoltaic panel; the camera end of another camera 2 is tilted upwards to capture the lower side of the photovoltaic panel; a third rotating shaft 509 is vertically rotatably connected to the support strip 502; a third pulley 510 is keyed to the upper end of the third rotating shaft 509; a fourth pulley 511 is connected to the third pulley 510 via a synchronous belt drive; the fourth pulley 511 is keyed to the upper end of the second rotating shaft 505; the lower end of the third rotating shaft 509 is vertically rotatably connected to the mounting block 404; a horizontally arranged section below the third rotating shaft 509 is connected to the first slide rail 401. A parallel splined shaft 512; a second support block 516 is rotatably connected to one end of the splined shaft 512 near the hollow shaft 303; the second support block 516 is bolted to the upper surface of the base 1; a directional sleeve 513 is slidably sleeved on the outer periphery of the splined shaft 512; the directional sleeve 513 can slide on the splined shaft 512 and rotate synchronously with the splined shaft 512; the directional sleeve 513 is inserted into the first slider 402 and is rotatably connected to the first slider 402; a third bevel gear 514 is keyed to the outer periphery of the directional sleeve 513; a fourth bevel gear 515 meshes with the third bevel gear 514; the fourth bevel gear 515 is keyed to the lower end of the third rotating shaft 509.In use, when the short or long side of the photovoltaic panel is parallel to the length direction of the bracket 405, the first incomplete gear 306 separates from the first gear 307, meaning the photovoltaic panel is stationary. The spline shaft 512 drives the directional sleeve 513 to rotate, causing the directional sleeve 513 to drive the elastic telescopic rod 506 to swing horizontally via the third bevel gear 514, the fourth bevel gear 515, the third rotating shaft 509, the third pulley 510, the fourth pulley 511, and the second rotating shaft 505. This allows the transmission block 507 to slide from one end of the guide rod 508 to the other. At the same time, the camera 2 continuously captures images of the side of the photovoltaic panel, effectively ensuring the detection effect of the photovoltaic panel.

[0039] Example 5:

[0040] Based on Example 4, as follows Figures 3-4 and Figure 9As shown, the rotating mechanism 3 and the shifting mechanism 5 are connected by a transmission mechanism 6. The transmission mechanism 6 includes a third support block 601 bolted to the lower surface of the base 1, and a fourth rotating shaft 602 and a fifth rotating shaft 603 rotatably connected to the base 1 side by side. A sixth rotating shaft 604 parallel to the spline shaft 512 is rotatably connected to the third support block 601. A fifth bevel gear 605 is keyed to one end of the sixth rotating shaft 604. A sixth bevel gear 606 meshes with the fifth bevel gear 605. The sixth bevel gear 606 is keyed to the lower end of the first rotating shaft 302. A rotating rod 607 is obliquely bolted to the other end of the sixth rotating shaft 604. The angle between the rotating rod 607 and the sixth rotating shaft 604 is approximately 135°. A U-shaped rod 608 is obliquely arranged on one side of the rotating rod 607. Both ends of the U-shaped rod 608 are rotatably connected to the lower end of the fourth rotating shaft 602; the middle arm of the U-shaped rod 608 is rotatably connected to a positioning shaft 613 parallel to its side arm; the end of the rotating rod 607 away from the sixth rotating shaft 604 is bolted to the positioning shaft 613; the upper end of the fourth rotating shaft 602 is keyed to a second incomplete gear 609; a second gear 610 is provided on one side of the second incomplete gear 609; the second gear 610 can mesh with the second incomplete gear 609; the second gear 610 is keyed to the lower end of the fifth rotating shaft 603; the upper end of the fifth rotating shaft 603 is keyed to a seventh bevel gear 611; an eighth bevel gear 612 meshes with the seventh bevel gear 611; the eighth bevel gear 612 is keyed to the end of the splined shaft 512 near the hollow shaft 303. In use, after the first incomplete gear 306 separates from the first gear 307, the first rotating shaft 302 continues to rotate and drives the sixth rotating shaft 604 to rotate via the sixth bevel gear 606 and the fifth bevel gear 605. This causes the sixth rotating shaft 604 to drive the rotating rod 607 to rotate, thus enabling the rotating rod 607 to drive the fourth rotating shaft 602 to rotate horizontally by a certain angle via the U-shaped rod 608. When the fourth rotating shaft 602 rotates, it drives the second incomplete gear 609 to mesh with the second gear 610, causing the second gear 610 to drive the splined shaft 512 to rotate via the fifth rotating shaft 603, the seventh bevel gear 611, and the eighth bevel gear 612. This allows the transmission block 507 to slide from one end of the guide rod 508 to the other end. When the rotating rod 607... After rotating 180°, the second incomplete gear 609 separates from the second gear 610, and at this time, the first incomplete gear 306 meshes with the first gear 307. Then, the photovoltaic panel is rotated horizontally and the distance between the camera 2 and the photovoltaic panel is adjusted. After the photovoltaic panel rotates horizontally by 90°, the first incomplete gear 306 separates from the first gear 307 again and the second incomplete gear 609 meshes with the second gear 610 again. Then, the transmission mechanism 6 drives the transmission block 507 to slide from one end of the guide rod 508 to the other end, repeating the above actions, thereby realizing the detection of each of the four sides of the photovoltaic panel, effectively ensuring the detection efficiency and effect of the photovoltaic panel.
