[0038] By placing the solar panel on the top of the concave slot body 2 31, and then starting the stepper motor 341, the stepper motor 341 works stably under the fixation of the motor slot 1 36, and its output end drives the rotating shaft 342 to rotate. Due to the connection relationship between the rotating shaft 342 and the belt 343 and the connecting shaft 344, the belt 343 transmits the rotational force of the rotating shaft 342 to the connecting shaft 344, so that the connecting shaft 344 also rotates, and the rotation of the connecting shaft 344 drives the bidirectional threaded rod 345 to rotate synchronously. The rotation of the bidirectional threaded rod 345 causes the two symmetrical sliders 2 346 to approach or move away from each other under the action of the threads. The concave slide grooves 347 fixedly connected to the two sliders 2 346 are guided by the sliding sleeve 2 349 and the sliding rod 2 340. The smooth movement along the direction of the second slide bar 340 ensures the stability of the concave slide groove 347 during the movement, and also ensures the stability of the solar panel 5 during the clamping process. As the second slide bar 346 approaches, the rubber pad 348 in the concave slide groove 347 gradually approaches the outer wall of the solar panel 5. The material of the rubber pad 348 has excellent elasticity and anti-slip properties, and can fit tightly on the outer wall of the solar panel 5 to achieve stable clamping. This clamping method not only ensures the stability of the solar panel 5 during the detection process, but also avoids damage to the solar panel 5 caused by over-tight clamping. At the same time, due to the precise control of the stepper motor three 341, the moving speed and position of the second slide bar 346 can be precisely controlled, so that The precise clamping of the solar panel 5 is achieved, which not only improves the accuracy of the detection, but also improves the working efficiency of the entire detection device. In addition, the threaded connection between the slider 1 38 fixedly connected to the right side of the concave trough body 2 31 and the screw rod 39, and the movable connection between the sleeve 1 302 and the slide rod 1 303 provide the concave trough body 2 31 with the ability to move in the horizontal direction. When the position of the solar panel 5 needs to be adjusted, the stepper motor 2 301 can be started to drive the rotating shaft 2 30 to rotate the screw rod 39. The rotation of the screw rod 39 drives the slider 1 38 to move on the outer wall of the screw rod 39, and drives the sleeve 1 302 to slide on the slide rod 1 303, thereby driving the concave trough body 2 31 and the solar panel 5 thereon to move together, so that the entire detection The device is more flexible in the detection process, and can adapt to the detection requirements of solar panels 5 of different sizes, realizes stable clamping and precise movement of the solar panel 5, and improves the accuracy and efficiency of the detection. When the stepper motor 2 301 is started, the two stepper motors 1 27 are started, and the stepper motor 1 27 drives the rotating shaft 1 26 to rotate, so that the cleaning roller 29 starts to rotate on the top of the guide plate 1 20. The surface of the cleaning roller 29 is usually made of soft cleaning material, which can effectively remove dust and stains on the surface of the solar panel 5 and keep its surface clean. As the cleaning roller 29 rotates, its bottom rotates on the surface of the solar panel 5 under the guidance of the guide plate 1 20, thereby achieving comprehensive cleaning of its surface.At the same time, the guide plates 202 fixedly connected to the front and rear sides of the top of the connecting plate 201 are guided by the concave guide frame 13, so that the entire cleaning structure 2 can move smoothly along the top of the concave mounting groove 1, and the two connecting plates 201 are moved to adjust the distance between the two cleaning rollers 29 by moving the two concave slide grooves 347, ensuring the stability and accuracy of the cleaning rollers 29 during the cleaning process.

[0039] like Figure 7 As shown, the adjustment structure 4 includes a convex support platform 41, a motor slot 2 42 is provided on the front side of the convex support platform 41, a circular movable hole 4 is provided on the top of the inner wall of the motor slot 2 42 and penetrates to the outside, a rotating shaft 44 is movably connected to the inner wall of the circular movable hole 44, a protective plate 2 43 is fixedly connected to the front of the inner wall of the motor slot 2 42, a stepping motor 45 is fixedly connected to the bottom of the rotating shaft 44, the bottom of the stepping motor 45 is fixedly connected to the inner wall of the motor slot 2 42, a spiral rod 46 is fixedly connected to the top of the rotating shaft 44, an inner threaded cylinder 47 is threadedly connected to the outer wall of the spiral rod 46, a mounting cylinder 48 is fixedly connected to the rear side of the top of the convex support platform 41, a limiting rod 49 is movably connected to the inner wall of the mounting cylinder 48, and the limiting rod 49 and the top of the inner threaded cylinder 47 are both fixedly connected to a top plate 40, a fixing plate 401 is fixedly connected to the top of the two top plates 40, and the top of the fixing plate 401 is fixedly connected to the bottom of the concave slot body 11;

[0040] The stepper motor 45 is started to drive the rotating shaft 44 to rotate, thereby rotating the screw rod 46. The threaded connection between the screw rod 46 and the internal threaded cylinder 47 allows the internal threaded cylinder 47 to be lifted and lowered in the vertical direction under the rotation of the screw rod 46. The top of the internal threaded cylinder 47 is fixedly connected to the top plate 40, so the top plate 40 and the internal threaded cylinder 47 are lifted and lowered together. At the same time, the limit rod 49 is movably connected to the installation cylinder 48, ensuring the stability of the top plate 40 and the internal threaded cylinder 47 during the lifting process, avoiding the normal operation thereof being affected by deviation or shaking, and the top of the two top plates 40 is fixedly connected to the fixed plate 4 01 is fixedly connected, and the top of the fixing plate 401 is fixedly connected to the bottom of the concave trough body 11. Therefore, when the top plate 40 and the internal threaded cylinder 47 are lifted or lowered, the fixing plate 401 and the concave trough body 11 connected thereto will also perform synchronous lifting and lowering movements. According to actual needs, the lifting height of the concave trough body 11 can be accurately controlled by adjusting the rotation direction and rotation speed of the stepping motor four 45, thereby adjusting the relative position between the solar cell panel 5 and the detection device, thereby improving the flexibility of detection, adapting to the operating habits of different staff members, improving the applicability of the detection device, and greatly broadening its scope of application.

[0041] In addition, the present invention also relates to a method for using a detection device for a crystalline silicon solar cell panel, comprising the following steps:

[0042] Step 1: First, place the crystalline silicon solar panel 5 to be tested on the top of the second concave trough body 31, ensuring that the bottom of the solar panel 5 maintains an appropriate distance from the inner wall of the second concave trough body 31 for subsequent fixing and moving operations.

[0043] Step 2: Start the stepper motor 341 to drive the driving shaft 342 to rotate, and then drive the belt 343 and the connecting shaft 344 to rotate. During this process, the bidirectional threaded rod 345 will rotate synchronously, so that the two sliders 2 346 move toward or away from each other along the thread direction of the bidirectional threaded rod 345. Since the top of the slider 2 346 is fixedly connected to the concave groove 347, and the concave groove 347 is movably connected to the connecting plate 201, when the slider 2 346 moves, it will drive the connecting plate 201, the guide plate 1 20 and the cleaning roller 29 to move accordingly, so as to achieve the clamping and fixation of the two sides of the solar cell panel 5.

[0044] Step 3: After the clamping and fixing is completed, start the stepper motor 2 301 to drive the rotation of the rotating shaft 2 30 and the screw 39. Since the screw 39 is threadedly connected to the slider 1 38, and the slider 1 38 is fixedly connected to the right side of the concave groove body 2 31, the rotation of the screw 39 will drive the slider 1 38 and the concave groove body 2 31 to move in the horizontal direction under the guidance of the slide bar 1 303, thereby driving the solar panel 5 to move to the cleaning structure 2.

[0045] Step 4: After the solar panel 5 moves to the bottom of the cleaning structure 2, start the two stepper motors 27 to drive the rotation of the rotating shaft 26 and the cleaning roller 29. The cleaning roller 29 rolls along the surface of the solar panel 5 with the support of the guide plate 20 to clean the surface of the solar panel 5. At the same time, since the guide plate 1 20 and the guide plate 202 are movably connected to the rectangular through hole and the concave guide frame 13 respectively, the cleaning roller 29 can maintain a stable posture during the rolling process to ensure the uniformity and consistency of the cleaning effect.

[0046] Step 5: After cleaning, the solar panel 5 is moved to the inspection area for subsequent inspection work. During the inspection process, the height and angle of the adjustment structure 4 can be adjusted as needed to meet different inspection requirements and the needs of different staff members.

[0047] The working principle of the present invention is as follows: by placing the solar panel on the top of the concave slot body 2 31, and then starting the stepper motor 341, the stepper motor 341 works stably under the fixation of the motor slot 1 36, and its output end drives the rotating shaft 342 to rotate. Due to the connection relationship between the rotating shaft 342 and the belt 343 and the connecting shaft 344, the belt 343 transmits the rotational force of the rotating shaft 342 to the connecting shaft 344, so that the connecting shaft 344 also rotates, and the rotation of the connecting shaft 344 drives the bidirectional threaded rod 345 to rotate synchronously. The rotation of the bidirectional threaded rod 345 causes the two symmetrical sliders 2 346 to move closer to or away from each other under the action of the threads. The concave slide grooves 347 fixedly connected on the two sliders 2 346 are connected to the sleeve 2 349 and the slider 2 Under the guidance of the second slide bar 340, it moves smoothly along the direction of the second slide bar 340, ensuring the stability of the concave slide groove 347 during the movement, and also ensuring the stability of the solar panel 5 during the clamping process. As the second slide bar 346 approaches, the rubber pad 348 in the concave slide groove 347 gradually approaches the outer wall of the solar panel 5. The material of the rubber pad 348 has excellent elasticity and anti-slip properties, and can fit tightly on the outer wall of the solar panel 5 to achieve stable clamping. This clamping method not only ensures the stability of the solar panel 5 during the detection process, but also avoids damage to the solar panel 5 caused by over-tight clamping. At the same time, due to the precise control of the stepper motor three 341, the moving speed and The position can be precisely controlled, thereby achieving precise clamping of the solar cell panel 5, which not only improves the accuracy of the detection, but also improves the working efficiency of the entire detection device. In addition, the threaded connection between the slider 1 38 fixedly connected to the right side of the concave trough body 2 31 and the screw rod 39, and the movable connection between the sleeve 1 302 and the slide rod 1 303 provide the concave trough body 2 31 with the ability to move in the horizontal direction. When it is necessary to adjust the position of the solar cell panel 5, the stepper motor 2 301 can be started to drive the rotating shaft 2 30 to rotate the screw rod 39. The rotation of the screw rod 39 drives the slider 1 38 to move on the outer wall of the screw rod 39, and drives the sleeve 1 302 to slide on the slide rod 1 303, thereby driving the concave trough body 2 31 and the solar cell thereon The panel 5 moves together, making the entire detection device more flexible during the detection process, and can adapt to the detection requirements of solar panels 5 of different sizes, achieving stable clamping and precise movement of the solar panel 5, and improving the accuracy and efficiency of the detection. When the stepper motor 2 301 is started, the two stepper motors 1 27 are started, and the stepper motor 1 27 drives the rotating shaft 1 26 to rotate, so that the cleaning roller 29 starts to rotate on the top of the guide plate 1 20. The surface of the cleaning roller 29 is usually made of soft cleaning material, which can effectively remove dust and stains on the surface of the solar panel 5 and keep its surface clean. As the cleaning roller 29 rotates, its bottom rotates on the surface of the solar panel 5 under the guidance of the guide plate 1 20.Thus, the surface thereof can be fully cleaned. At the same time, the guide plates 202 fixedly connected to the front and rear sides of the top of the connecting plate 201 are guided by the concave guide frame 13, so that the entire cleaning structure 2 can move smoothly along the top of the concave mounting groove 1, and the two connecting plates 201 are driven to move by the two concave slide grooves 347 to adjust the distance between the two cleaning rollers 29, thereby ensuring the stability and accuracy of the cleaning rollers 29 during the cleaning process;

[0048] The stepper motor 45 is started to drive the rotating shaft 44 to rotate, thereby rotating the screw rod 46. The threaded connection between the screw rod 46 and the internal threaded cylinder 47 allows the internal threaded cylinder 47 to be lifted and lowered in the vertical direction under the rotation of the screw rod 46. The top of the internal threaded cylinder 47 is fixedly connected to the top plate 40, so the top plate 40 and the internal threaded cylinder 47 are lifted and lowered together. At the same time, the limit rod 49 is movably connected to the installation cylinder 48, ensuring the stability of the top plate 40 and the internal threaded cylinder 47 during the lifting process, avoiding the normal operation thereof being affected by deviation or shaking, and the top of the two top plates 40 is fixedly connected to the fixed plate 4 01 is fixedly connected, and the top of the fixing plate 401 is fixedly connected to the bottom of the concave trough body 11. Therefore, when the top plate 40 and the internal threaded cylinder 47 are lifted or lowered, the fixing plate 401 and the concave trough body 11 connected thereto will also perform synchronous lifting and lowering movements. According to actual needs, the lifting height of the concave trough body 11 can be accurately controlled by adjusting the rotation direction and rotation speed of the stepping motor four 45, thereby adjusting the relative position between the solar cell panel 5 and the detection device, thereby improving the flexibility of detection, adapting to the operating habits of different staff members, improving the applicability of the detection device, and greatly broadening its scope of application.
