Description

Technical Field

[0001] This invention relates to the field of photovoltaic processing technology, specifically to a device for processing and testing photovoltaic modules. Background Technology

[0002] Photovoltaic power generation is playing an increasingly important role in the global energy sector, and is widely used in rooftop power generation, large-scale photovoltaic power plants, distributed energy systems, and other fields. It helps reduce dependence on traditional fossil fuels and promotes energy transition and sustainable development.

[0003] To reduce photovoltaic (PV) module failures and ensure power generation efficiency, performance testing of PV modules is essential. Microcracks in PV panels are a significant cause of reduced power generation and safety performance. Therefore, crack detection is a crucial step. Current PV panel testing primarily relies on manual touch inspection, which is inefficient and prone to missing minute cracks. Summary of the Invention

[0011] As a further embodiment of the present invention: the clamping and picking mechanism includes an adjusting plate, on which a guide rail three is horizontally arranged, and a clamp one and a clamp two are mounted on the guide rail three. The clamp one is fixedly installed between the guide rail three and the end of the dark light box is fixedly installed between the clamp one. A clamping assembly is provided between the clamp two and the guide rail three. The clamping assembly includes a push-pull block, which is engaged with both sides of the clamp two. A pin is provided inside the push-pull block, which passes through the clamp two, and a retaining spring is provided between the pin and both sides of the clamp two. A clamping motor is fixedly installed on the adjusting plate, and the clamping motor is connected to a threaded rod, which is threadedly connected to the upper end of the push-pull block.

[0012] As a further embodiment of the present invention: the translation adjustment assembly includes a fixed frame first fixedly installed at both ends of the frame, a horizontal guide rail first provided on the fixed frame first, a translation frame first slidably installed on the horizontal guide rail first, a rotating roller rotatably installed on the translation frame first, a conveyor belt installed between the two rotating rollers, a drive motor first fixedly installed at the bottom of the translation frame first, a drive belt provided between the drive motor first and the rotating roller, a second drive motor and a pulley first provided at the bottom of the fixed frame first, a belt first provided between the second drive motor and the pulley first, a connecting block first provided at the bottom of the translation frame first, the connecting block first being fixedly connected to the belt first, and a transmission shaft provided between the pulleys first located at both ends of the frame.

[0013] As a further embodiment of the present invention: the alignment mechanism includes a fixed frame 2, a horizontal guide rail 2 is provided on the fixed frame 2, a translation frame 2 is slidably mounted on the horizontal guide rail 2, a drive motor 3 is fixedly provided on the fixed frame 2, a pulley 2 is connected to the drive motor 3, a belt 2 is provided on the pulley 2, a connecting block 2 is provided on the translation frame 2, the connecting block 2 is fixedly connected to the belt 2, and an alignment push plate is connected to the bottom of the translation frame 2.

[0014] As a further embodiment of the present invention: the reflective film is provided with adhesive on the side facing the photovoltaic panel, and the surface of the pressure roller is provided with a rubber layer.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) A bending frame is installed in conjunction with the suspension guide rail and the suspension frame. The detection lamp plate and the photosensitive plate are set parallel to each other on the bottom rear side of the bending frame. After the reflective film is laid on the surface of the photovoltaic panel, the detection lamp plate shines light on the reflective film at a certain angle. After being reflected by the reflective film, the light is received by the photosensitive plate. If there are no defects such as cracks on the photovoltaic panel, the reflective film will completely reflect the detection light and it will be received by the photosensitive plate. Otherwise, the intensity of the light received by the photosensitive plate will change, thereby determining whether there are processing defects such as cracks or unevenness in the photovoltaic panel.

[0017] (2) The pressure roller is slidably installed in the vertical guide rail 2 through the sliding frame 2. The height of the pressure roller is controlled by the support spring 2, the lifting motor, and the push-pull frame, thereby realizing the contact or separation between the pressure roller and the photovoltaic panel. In order to facilitate the continuous release of the reflective film roller and its pressing and adhesion to the surface of the photovoltaic panel by the pressure roller, a recovery roller and a cutting blade are set at both ends of the pressure roller. When the reflective film is released, part of the reflective film at both ends will be wound and recovered by the recovery roller. At this time, when the pressure roller connected to the drive component continues to rotate, it will drive the reflective film roller to release the reflective film synchronously, thereby simplifying the release control of the reflective film.

[0018] (3) The photovoltaic panels on the conveyor belt are clamped and picked up using clamp one and clamp two. The adjusting plate is horizontally adjustable along the direction of the conveyor belt and can also be raised and lowered to facilitate the clamp one and clamp two to approach the photovoltaic panels on the conveyor belt. When the photovoltaic panel falls between clamp one and clamp two, the clamping motor is controlled to run, and the threaded rod drives the push-pull block to move along the guide rail three, thereby driving clamp two in the middle of the push-pull block to approach the end of the photovoltaic panel. After clamp two contacts the end of the photovoltaic panel, the threaded rod is controlled to rotate. At this time, clamp two abuts against the edge of the photovoltaic panel under the action of the abutment spring, avoiding excessive force during the clamping process and damaging the photovoltaic panel.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0035] Example 1:

[0036] like Figure 1 , Figure 2 As shown, a photovoltaic module processing and testing device includes a frame 1, a conveyor belt 2 on the frame 1, a photovoltaic panel to be tested being conveyed on the conveyor belt 2, the conveyor belt 2 being connected to a translation adjustment component 3, an alignment mechanism 4 on the frame 1, a clamping and picking mechanism 5 in the middle of the frame 1, the clamping and picking mechanism 5 being connected to a dark light box 6, a testing mechanism 7 being provided inside the dark light box 6, and the clamping and picking mechanism 5 picking up the photovoltaic panel on the conveyor belt 2 and placing it inside the dark light box 6.

[0037] like Figure 6 , Figure 8 As shown, the detection mechanism 7 includes a laying guide rail 70, which is symmetrically arranged on both sides of the interior of the darkroom 6. A translation frame 71 is slidably installed between the laying guide rails 70. Electric sliders 72 are provided on both sides of the translation frame 71 and are slidably installed between the electric sliders 72 and the laying guide rails 70. Pressure rollers 75 are lifted and lowered between the translation frames 71. A reflective film roller 77 is rotatably installed on the side of the translation frame 71. A reflective film is wound on the reflective film roller 77. A detection component is provided on the top of the translation frame 71.

[0038] Specifically, after being clamped by the clamping and picking mechanism 5, the photovoltaic panel falls into the dark light box 6, corresponding to the detection mechanism 7. The translation frame 71 drives the pressure roller 75 and the reflective film roller 77 to press and stick the reflective film onto the surface of the photovoltaic panel. While laying the reflective film, the detection component is used to detect cracks on the surface of the photovoltaic panel.

[0039] like Figure 11As shown, the detection assembly includes a suspension rail 714 mounted on the top of the darkroom 6. Two suspension rails 714 are arranged in parallel, and a rack 715 is arranged between the two suspension rails 714. A suspension frame 716 is slidably mounted between the suspension rails 714. A mating gear 717 is rotatably mounted between the suspension frames 716. The mating gear 717 meshes with the rack 715. A bending frame 718 is arranged between the suspension frame 716 and the translation frame 71. A detection lamp plate 719 and a photosensitive plate 720 are arranged in parallel at the bottom of the bending frame 718. The detection light emitted by the detection lamp plate 719 is reflected by the reflective film on the photovoltaic plate and then received by the photosensitive plate 720.

[0040] Specifically, a bending frame 718 is installed in conjunction with the suspension rail 714 and the suspension frame 716. A detection lamp plate 719 and a photosensitive plate 720 are arranged parallel to each other on the rear bottom of the bending frame 718. After the reflective film is laid on the surface of the photovoltaic panel, the detection lamp plate 719 shines light onto the reflective film at a certain angle. After being reflected by the reflective film, the light is received by the photosensitive plate 720. If there are no defects such as cracks on the photovoltaic panel, the reflective film will completely reflect the detection light and it will be received by the photosensitive plate 720. Otherwise, the intensity of the light received on the photosensitive plate 720 will change, thereby determining whether there are processing defects such as cracks or unevenness in the photovoltaic panel.

[0041] Furthermore, such as Figure 9 , Figure 10 As shown, a push-pull frame 73 is provided on the inner side of the translation frame 71. The two ends of the push-pull frame 73 are rotatably connected to the ends of the pressure roller 75. A lifting motor 74 is provided between the translation frame 71 and the push-pull frame 73. Vertical guide rails 7100 are symmetrically provided at both ends of the translation frame 71. Recycling rollers 76 are provided at both ends of the pressure roller 75. An annular rolling cutter 760 is provided on the edge of the recycling roller 76. Sliding frames 7101 are respectively connected to the ends of the pressure roller 75 and the recycling roller 76. The sliding frames 7101 are slidably installed between the vertical guide rails 7100 and the sliding frames 7101. A support spring 713 is provided between the sliding frames 7101 and the vertical guide rails. The pressure roller 75 is connected to a drive assembly.

[0042] Specifically, the pressure roller 75 is slidably mounted within the vertical guide rail 7100 via the sliding frame 7101. The height of the pressure roller 75 is controlled by the support spring 713, the lifting motor 74, and the push-pull frame 73, thereby achieving contact or separation between the pressure roller 75 and the photovoltaic panel. To facilitate the continuous release of the reflective film roller 77 and its pressing and adhesion to the photovoltaic panel surface by the pressure roller 75, a recovery roller 76 and a cutting blade 760 are installed at both ends of the pressure roller 75. When the reflective film is released, a portion of the reflective film at both ends will be wound and recovered by the recovery roller 76. At this time, the continuous rotation of the pressure roller 75 connected to the drive assembly will drive the reflective film roller 77 to synchronously release the reflective film, thus simplifying the release control of the reflective film.

[0043] Furthermore, such as Figure 9 As shown, the drive assembly includes a vertical guide rail 711 disposed on the side of the translation frame 71, a sliding frame 710 slidably mounted inside the vertical guide rail 711, a support spring 712 disposed between the sliding frame 710 and the vertical guide rail 711, a follower motor 79 disposed on the sliding frame 710, a drive pulley 78 disposed at the end of the recovery roller 76, and a transmission steel belt 780 disposed between the drive pulley 78 and the follower motor 79.

[0044] Specifically, since the pressure roller 75 is installed in the vertical guide rail 7100, in order to ensure reliable power transmission, a vertical guide rail 711 is set on the side of the translation frame 71. Power is transmitted in conjunction with the drive pulley 78, the transmission steel belt 780, and the follower motor 79. When the pressure roller 75 descends, the drive pulley 78 and the transmission steel belt 780 will synchronously pull the sliding frame 710 down. The setting of the transmission steel belt 780 ensures reliable power transmission and pulls the follower motor 79 to move.

[0045] Furthermore, such as Figure 6 , Figure 7 As shown, the clamping and picking mechanism 5 includes an adjusting plate 50, on which a guide rail 3 51 is horizontally arranged. A clamp 1 52 and a clamp 2 53 are installed on the guide rail 3 51. The clamp 1 52 is fixedly installed between the guide rail 3 51 and the end of the dark light box 6 is fixedly installed between the clamp 1 52 and the clamp 2 53. A clamping assembly 54 is provided between the clamp 2 53 and the guide rail 3 51. The clamping assembly 54 includes a push-pull block 540. The push-pull block 540 is engaged with both sides of the clamp 2 53. A pin 541 is provided inside the push-pull block 540. The pin 541 passes through the clamp 2 53, and an abutment spring 542 is provided between the pin 541 and both sides of the clamp 2 53. A clamping motor 544 is fixedly installed on the adjusting plate 50. The clamping motor 544 is connected to a threaded rod 543. The threaded rod 543 is threadedly connected to the upper end of the push-pull block 540.

[0046] Specifically, the photovoltaic panels on the conveyor belt 2 are clamped and picked up using clamp 1 52 and clamp 2 53. The adjusting plate 50 is horizontally adjustable along the direction of the conveyor belt 2 and can also be raised and lowered, facilitating the proximity of clamp 1 52 and clamp 2 53 to the photovoltaic panels on the conveyor belt 2. When the photovoltaic panel falls between clamp 1 52 and clamp 2 53, the clamping motor 544 is activated, and the threaded rod 543 drives the push-pull block 540 to move along the guide rail 3 51. This causes clamp 2 53 in the middle of the push-pull block 540 to approach the end of the photovoltaic panel. After clamp 2 53 contacts the end of the photovoltaic panel, the threaded rod 543 continues to rotate. At this time, clamp 2 53, driven by the abutment spring 542, abuts against the edge of the photovoltaic panel, preventing excessive force during clamping and damage to the photovoltaic panel.

[0047] Example 2:

[0048] This embodiment is a further improvement and limitation on Embodiment 1 based on Embodiment 1.

[0049] An embodiment including all the components in Example 1, further comprising:

[0050] Furthermore, such as Figure 3 , Figure 4 As shown, the translation adjustment assembly 3 includes a fixed frame 30 fixedly installed at both ends of the frame 1. A horizontal guide rail 31 is provided on the fixed frame 30. A translation frame 35 is slidably installed on the horizontal guide rail 31. A rotating roller 36 is rotatably installed on the translation frame 35. The conveyor belt 2 is installed between the rotating rollers 36 at both ends. A drive motor 37 is fixedly installed at the bottom of the translation frame 35. A drive belt 38 is provided between the drive motor 37 and the rotating roller 36. A second drive motor 311 and a pulley 32 are provided at the bottom of the fixed frame 30. A belt 33 is provided between the second drive motor 311 and the pulley 32. A connecting block 310 is provided at the bottom of the translation frame 35. The connecting block 310 is fixedly connected to the belt 33. A transmission shaft 39 is provided between the pulleys 32 at both ends of the frame 1.

[0051] Specifically, since the photovoltaic panels are placed in different positions on the conveyor belt 2, in order to ensure that the clamping and picking mechanism 5 can reliably pick up the photovoltaic panels, a translation frame 35 is slidably installed on the horizontal guide rail 31. Combined with the drive motor 311 driving the belt 33 to move, when the belt 33 moves, the connecting block 310 connected to the belt 33 moves synchronously, thereby driving the translation frame 35 on the horizontal guide rail 31 to slide, thereby adjusting the relative position between the photovoltaic panels on the conveyor belt 2 and the clamping and picking mechanism 5.

[0052] Furthermore, such as Figure 5As shown, the alignment mechanism 4 includes a fixed frame 40, a horizontal guide rail 44 on the fixed frame 40, a translation frame 45 slidably mounted on the horizontal guide rail 44, a drive motor 41 fixedly mounted on the fixed frame 40, a pulley 42 connected to the drive motor 41, a belt 43 mounted on the pulley 42, a connecting block 46 on the translation frame 45, the connecting block 46 being fixedly connected to the belt 43, and an alignment push plate 47 connected to the bottom of the translation frame 45.

[0053] Specifically, the drive motor 41 controls the belt 43 to move, which in turn drives the connecting block 46 to move, causing the translation frame 45 to slide along the horizontal guide rail 44. The alignment push block connected to the bottom of the translation frame 45 pushes the photovoltaic panel on the conveyor belt 2 back and forth, thereby controlling the photovoltaic panel to enter the clamping and picking mechanism 5 in an aligned state, thus ensuring the reliable picking of the photovoltaic panel.

[0054] Furthermore, the reflective film has an adhesive layer on the side facing the photovoltaic panel, and the surface of the pressure roller 75 has a rubber layer.

[0055] Specifically, the rubber layer on the surface of the pressure roller 75 can improve the adhesion between the reflective film and the photovoltaic panel surface, ensuring that the reflective film can display cracks when it encounters them, so that they can be detected by the testing agency 7.

[0056] The working principle of this invention embodiment is as follows:

[0057] like Figures 1-11As shown, after being clamped by the clamping and picking mechanism 5, the photovoltaic panel falls into the dark light box 6, corresponding to the detection mechanism 7. The translation frame 71 drives the pressure roller 75 and the reflective film roller 77 to press and stick the reflective film onto the surface of the photovoltaic panel. While the reflective film is being laid, the detection components are used to detect cracks on the surface of the photovoltaic panel. A bending frame 718 is installed in conjunction with the suspension guide rail 714 and the suspension frame 716. The detection light plate 719 and the photosensitive plate 720 are arranged parallel to each other on the rear bottom of the bending frame 718. After the reflective film is laid on the surface of the photovoltaic panel, the detection light plate 719 shines light onto the reflective film at a certain angle. After being reflected by the reflective film, the light is received by the photosensitive plate 720. If there are no defects such as cracks on the photovoltaic panel, the reflective film will completely reflect the detection light and it will be received by the photosensitive plate 720. Otherwise, the intensity of the light received by the photosensitive plate 720 will change, thereby determining whether there are processing defects such as cracks or unevenness on the photovoltaic panel. The pressure roller 75 is slidably mounted within the vertical guide rail 7100 via the sliding frame 7101. The height of the pressure roller 75 is controlled by the support spring 713, lifting motor 74, and push-pull frame 73, thereby achieving contact or separation between the pressure roller 75 and the photovoltaic panel. To facilitate the continuous release of the reflective film roller 77 and its pressing and adhesion to the photovoltaic panel surface by the pressure roller 75, a recovery roller 76 and a cutting blade 760 are installed at both ends of the pressure roller 75. When the reflective film is released, a portion of the reflective film at both ends will be wound and recovered by the recovery roller 76. At this time, the continuous rotation of the pressure roller 75 connected to the drive assembly will drive the reflective film roller 77 to synchronously release the reflective film, thus simplifying the release control of the reflective film. Since the pressure roller 75 is installed within the vertical guide rail 7100, a vertical guide rail 711 is provided on the side of the translation frame 71 to ensure reliable power transmission. Power is transmitted via the drive pulley 78, transmission steel belt 780, and follower motor 79. When the pressure roller 75 descends, the drive pulley 78, in conjunction with the transmission steel belt 780, synchronously pulls the sliding frame 710 downwards. The transmission steel belt 780 ensures reliable power transmission and the movement of the follower motor 79. The photovoltaic panels on the conveyor belt 2 are clamped and picked up using clamps 52 and 53. The adjusting plate 50 is horizontally adjustable along the direction of the conveyor belt 2 and can also be raised and lowered, facilitating the clamps 52 and 53 to approach the photovoltaic panels on the conveyor belt 2. When the photovoltaic panel is placed between clamp 1 52 and clamp 2 53, the clamping motor 544 is controlled to operate. The threaded rod 543 drives the push-pull block 540 to move along the guide rail 3 51, thereby driving the clamp 2 53 in the middle of the push-pull block 540 to approach the end of the photovoltaic panel. After the clamp 2 53 contacts the end of the photovoltaic panel, the threaded rod 543 is controlled to rotate. At this time, the clamp 2 53 abuts against the edge of the photovoltaic panel under the action of the abutment spring 542, so as to avoid excessive force during the clamping process and damage to the photovoltaic panel.Since the photovoltaic panels are placed in different positions on the conveyor belt 2, in order to ensure that the clamping and picking mechanism 5 can reliably pick up the photovoltaic panels, a translation frame 35 is slidably installed on the horizontal guide rail 31. Combined with the drive motor 311 driving the belt 33, when the belt 33 moves, the connecting block 310 connected to the belt 33 moves synchronously, thereby causing the translation frame 35 on the horizontal guide rail 31 to slide, thus adjusting the relative position between the photovoltaic panels on the conveyor belt 2 and the clamping and picking mechanism 5. The drive motor 41 controls the movement of the belt 43, which in turn drives the connecting block 46 to move, causing the translation frame 45 to slide along the horizontal guide rail 44. The alignment push block connected to the bottom of the translation frame 45 pushes the photovoltaic panels on the conveyor belt 2 back and forth, thereby controlling the photovoltaic panels to enter the clamping and picking mechanism 5 in an aligned state, thus ensuring the reliable picking up of the photovoltaic panels.
