Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic panel detection, and particularly to an automatic detection device for solar photovoltaic panels and a detection method thereof. Background Art

[0002] A solar photovoltaic system, also known as photovoltaics, is a facility that converts solar energy into direct current electricity using the photovoltaic effect of photovoltaic semiconductor materials. The photovoltaic system mainly converts solar energy into electricity through solar photovoltaic panels. In the existing production process of photovoltaic panels, semiconductors are mainly used as power generation materials, and the existing semiconductor power generation materials mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride.

[0003] The existing solar photovoltaic panel components are mainly adhesively connected through solar cells, glass, and a backplane, and are stacked to form a solar photovoltaic panel. During the bonding process, the perimeter of the photovoltaic panel assembly is mainly bonded by gluing. During the production process, the solar cells are first fixed between the glass sheet and the support backplane, and the glass sheet and the support backplane play a role in limiting and fixing the solar cell panel to prevent the solar cells from falling off. During the stacking combination, the sealing protection can be improved through the glue layer. The gluing method mainly bonds the contact surfaces of the cells, the glass sheet layer, and the support backplane through a gluing material. Therefore, the quality of the glue bonding affects the performance, life, and reliability of the photovoltaic panel. In the existing production process, most products are detected and judged whether they are qualified by detecting the appearance of glue layer bubbles and damaging the glue joint by a CCD camera. The method of using a CCD camera for detection can only identify whether there are defects in the appearance of the glue, and cannot identify whether there are bubbles at the glue joint, thus unable to ensure the detection accuracy. When the glue joint is damaged for internal detection, the product will be damaged, and it is impossible to perform non-destructive and comprehensive detection of the glue bonding of the solar photovoltaic panel.

[0004] Refer to the Chinese invention patent with the patent application number "CN2022103285873" and the patent name "A bubble detection device for solar photovoltaic panels". This technical solution discloses "A bubble detection device for solar photovoltaic panels, including a conveyor belt for conveying the photovoltaic panels to be detected. There are symmetrically arranged vertical frames on both sides of the conveyor belt. Two transparent plates are fixedly connected between the vertical frames, and a light passing slit is formed between the two transparent plates. A linear light source fixedly connected to the vertical frames is arranged directly above the light passing slit. At least one image sensor is arranged above the linear light source. The image sensor is fixedly connected to the vertical frames through a bracket. An optical enhancement layer is bonded to the side of the transparent plate close to the photovoltaic panel to be detected. The reflected light forms light spots on the optical enhancement layer. The image sensor is connected to a controller". Although this technical solution can photograph the light spots on the optical enhancement layer by the image sensor and calculate and judge the size of the bubbles through the controller to achieve automatic detection of the bonding condition of the bubbles at the bonding part of the photovoltaic panel, and although the work efficiency is improved, this technical solution uses a camera detection method. The camera detection has high requirements for the lighting environment and is easily affected by the ambient lighting conditions, affecting the detection accuracy. And when using camera detection to detect transparent and highly reflective objects, the detection result is affected due to the easy generation of light reflection. And this technical solution cannot be applied to detect photovoltaic panels with different thickness dimensions, and the applicable range is relatively low.

[0039] Specifically, a plurality of movable cross beams 1 are provided. The plurality of movable cross beams 1 are flush with each other. When any one of the movable cross beams 1 is located between the detection light source 6 and the light receiving flat plate 7, the central axis of the detection light source 6 and the central axis of the light receiving flat plate 7 are both on the same central axis.

[0040] Embodiment 1. To achieve non-destructive detection of the glued joints of photovoltaic panels automatically, since the existing photovoltaic panel assemblies need to detect air bubbles at the glued joints after gluing and assembling, and judge whether the gluing state meets the standard by obtaining air bubble images. The existing detection methods mainly use destroying the glue connection and CCD camera detection. Detecting by destroying the glue connection is likely to damage the photovoltaic panel. If using a CCD camera for detection, only the appearance defects of the glued joints can be judged, and the internal air bubble state of the glued joints cannot be judged. Therefore, it is necessary to achieve non-destructive detection of air bubbles at the glued joints of photovoltaic panels. In this embodiment: There is a movable crossbeam 1, a light-shifting device 2, a plate-shifting device 3, and a conveying plane 4 for conveying the movable crossbeam 1; A placement flat plate 5 for placing the photovoltaic panel to be detected is arranged on one side of the movable crossbeam 1, a detection light source 6 is movably arranged directly above the conveying plane 4, and a light-receiving flat plate 7 is movably arranged directly below the conveying plane 4. The light-emitting port of the detection light source 6 faces one side of the placement flat plate 5, the light-receiving flat plate 7 faces the other side of the placement flat plate 5, and the detection light source 6 and the light-receiving flat plate 7 are corresponding. The detection light source 6 can be used to emit X-ray beams, and the light-receiving flat plate 7 can be used to receive X-ray beams. Therefore, an X-ray detection station can be formed between the light-emitting surface of the detection light source 6 and the light-receiving surface of the light-receiving flat plate 7. The movable crossbeam 1 can be conveyed by the conveying plane 4 to stop between the detection stations, and the two sides of the photovoltaic panel on the placement flat plate 5 are respectively aligned with the light-emitting surface of the detection light source 6 and the light-receiving surface of the light-receiving flat plate 7, so that the X-ray beams released from the light-emitting surface of the detection light source 6 can pass through the glued joints of the photovoltaic panel and irradiate to the light-receiving surface of the light-receiving flat plate 7, and the light-receiving flat plate 7 can obtain the X-ray beam image. By judging the beam image, the internal air bubble state of the glued joints can be obtained, effectively achieving non-destructive detection of the glued joints of photovoltaic panels, improving work efficiency and detection accuracy.

[0041] It should be noted that before detection, the positions of the detection light source 6 and the light-receiving flat plate 7 need to be adjusted to ensure that the light-emitting surface of the detection light source 6 can be completely aligned with the light-receiving surface of the light-receiving flat plate 7. The light-receiving flat plate 7 can be arranged on the power output end of the plate-shifting device 3, and the detection light source 6 can also be arranged on the power output end of the light-shifting device 2. Furthermore, the moving distance of the light-receiving flat plate 7 can be controlled by the plate-shifting device 3, and the moving distance of the detection light source 6 can be controlled by the light-shifting device 2, so that the detection light source 6 can be completely aligned with the light-receiving flat plate 7.

[0042] It also should be noted that since the plate-shifting device 3 and the light-shifting device 2 have the same structure, and the light-receiving surface of the light-receiving flat plate 7 needs to face the light-emitting surface of the detection light source 6, therefore, when installing the light-receiving flat plate 7, the light-receiving flat plate 7 needs to be arranged on the top of the lifting flat plate 26 of the plate-shifting device 3.

[0043] Specifically, to reduce the situation that the shadow of the placement flat plate 5 affects the detection image, the placement flat plate 5 can be made of a light-transmitting material.

[0044] In the second embodiment, in order to realize the automatic detection of the photovoltaic panel, the detection light source 6 and the light receiving plate 7 can be synchronously moved, so that the detection light source 6 and the light receiving plate 7 are moved along the four sides of the photovoltaic panel for detection. Since the photovoltaic panel assembly needs to be glued along the four sides of the connection of the photovoltaic panel assembly during the gluing connection process, when the gluing parts of the photovoltaic panel assembly are detected, it is necessary to move the gluing parts around the photovoltaic panel for detection. In this embodiment: a plate moving device 3 and a light moving device 2 are provided, so that the light receiving plate 7 is provided on the power output end of the plate moving device 3, and the light moving device 2 and the plate moving device 3 have the same structure. The light moving device 2 includes a connecting plate 21 and at least two supporting plates 22. The two ends of the connecting plate 21 are respectively slidably arranged on the two supporting plates 22. By providing a displacement mechanism 23 at both ends of the connecting plate 21, the power output end of the displacement mechanism 23 is transmission-connected to the supporting plate 22 , and the displacement mechanism 23 can be used to control the moving distance of the connecting plate 21. A sliding plate 24 is movably provided on the connecting plate 21, and a lifting mechanism 25 is provided on the outside of the sliding plate 24. A lifting plate 26 is provided on the power output end of the lifting mechanism 25, so that the detection light source 6 is rotated and arranged at the bottom of the lifting plate 26. Therefore, the light moving device 2 can be used to control the activity range of the detection light source 6, and the plate moving device 3 can be used to control the activity range of the light receiving plate 7, which effectively realizes the three-axis adjustment of the position of the detection light source 6 and the light receiving plate 7 to ensure that the light emitting surface of the detection light source 6 and the light receiving surface of the light receiving plate 7 can be completely aligned, and during the detection process, the detection light source 6 and the light receiving plate 7 can be synchronously moved along the bonding parts around the photovoltaic panel, so as to achieve automatic all-round detection of the bonding parts around the photovoltaic panel, thereby improving work efficiency.

[0045] It should be added that the above-mentioned displacement mechanism 23 includes a moving motor 231 and a moving plate 232. The moving plate 232 is fixed to the end of the connecting plate 21, and the moving motor 231 is installed on one side of the moving plate 232, so that the other side of the moving plate 232 is slidably arranged on the supporting plate 22. By providing a transverse rack 221 on the supporting plate 22, and also by meshing the power output end of the moving motor 231 with the transverse rack 221, when the position of the connecting plate 21 needs to be adjusted, since the two ends of the connecting plate 21 are respectively arranged on two supporting plates 22, and the two ends of the connecting plate 21 are provided with a displacement mechanism 23, then when the moving motor 231 rotates, the moving plate 232 can be moved on the supporting plate 22, thereby realizing the adjustment of the position of the connecting plate 21 on the supporting plate 22, so as to facilitate the adjustment of the X-axis position of the detection light source 6.

[0046] It should also be added that by providing a longitudinal rack 211 on the top of the connecting plate 21, the longitudinal rack 211 is arranged to extend along the length direction of the connecting plate 21. Also, a driving motor 241 is provided outside the sliding plate member 24, and the power output end of the driving motor 241 is engaged with the longitudinal rack 211. When the driving motor 241 operates, the sliding plate member 24 can reciprocally slide along the length direction of the connecting plate 21. The driving motor 241 can be used to control the moving distance of the sliding plate member 24, thereby realizing the adjustment of the Y-axis position of the detection light source 6.

[0047] It should be added that the above-mentioned lifting mechanism 25 includes a connecting vertical plate 251 and a lifting motor 252. One side of the connecting vertical plate 251 is installed on the sliding plate member 24, and the lifting motor 252 is fixed outside the connecting vertical plate 251. A lifting lead screw 253 is rotatably arranged on the other side of the connecting vertical plate 251, and the lifting plate 26 is fixed outside the lifting lead screw 253. The power output end of the lifting motor 252 is also in transmission connection with the lifting lead screw 253. Therefore, the lifting mechanism 25 can be used to control the lifting height of the lifting plate 26. During the lifting adjustment process, the rotation direction of the lifting lead screw 253 can be controlled by the lifting motor 252 to realize the control of the lifting plate 26 to perform ascending or descending actions.

[0048] Regarding the above description, it should also be added that to enable rotational adjustment of the detection light source 6, a rotational motor is provided on the lifting plate 26, and the power output end of the rotational motor is in transmission connection with the detection light source 6. Thus, the rotational motor can be used to control the rotational direction of the detection light source 6.

[0049] Combined with the above description, it can be concluded that by driving the detection light source 6 to perform axial movement along the X-axis, Y-axis, Z-axis, and C-axis by the light moving device 2, and driving the light receiving plate 7 to perform axial movement along the X-axis, Y-axis, Z-axis, and C-axis by the plate moving device 3, the positions of the detection light source 6 and the light receiving plate 7 can be effectively adjusted automatically. And during the detection process, the synchronous movement of the detection light source 6 and the light receiving plate 7 can be achieved. Also, when moving axially along the X-axis and Y-axis, the detection light source 6 and the light receiving plate 7 can perform peripheral movement detection along the glue joints around the photovoltaic panel, achieving an all-round detection effect.

[0050] It should also be added that the moving motor 231, the lifting motor 252, and the driving motor 241 can all adopt servo motors. A servo motor is a rotary actuator or a linear actuator that allows precise control of angular velocity or linear position, speed, and acceleration.

[0051] Embodiment 3, in order to realize the automatic loading and unloading of photovoltaic panels, the photovoltaic panels need to be loaded onto the placement flat plate 5 before detection, and the photovoltaic panels need to be dropped from the placement flat plate 5 after the detection is completed, and the position of the photovoltaic panels on the placement flat plate 5 needs to be adjusted during the detection to ensure that the photovoltaic panels are not tilted on the placement flat plate 5. Since the photovoltaic panels are easily tilted on the placement flat plate 5 during the loading process, the side edges of the photovoltaic panels need to be limited during the loading process to ensure that the photovoltaic panels can remain flat on the placement flat plate 5. In this embodiment: a correction mechanism 8 is provided on the placement flat plate 5, and the correction mechanism 8 includes There are a positioning motor 81 and a positioning synchronous belt 82, and the power output end of the positioning motor 81 is connected to the positioning synchronous belt 82 in transmission, so that the conveying surface of the positioning synchronous belt 82 is flush with the side of the placement plate 5, and the positioning synchronous belt 82 can be driven by the positive and reverse rotation of the power output end of the positioning motor 81 to rotate clockwise / counterclockwise. The two ends of the movable crossbeam 1 are respectively provided with a limiting guide roller 11 and a feeding mechanism 12, and the limiting guide roller 11 can play a limiting role. The limiting guide roller 11 can be provided with multiple limiting guide rollers, so that the multiple limiting guide rollers 11 are all located on the same straight line, and the limiting guide roller 11 and the feeding mechanism 12 can be spaced apart from the placement plate 5, and the feeding mechanism 1 2 comprises a material receiving plate 121 and a feeding synchronous belt 122. By arranging feeding motors 123 on both sides of the outside of the material receiving plate 121, the power output end of the feeding motor 123 is connected to the feeding synchronous belt 122 for transmission, and the feeding synchronous belt 122 can be driven by the feeding motor 123 to rotate counterclockwise. Therefore, when the bottom surface of the photovoltaic panel to be detected is on the material receiving plate 121, the photovoltaic panel can be driven by the feeding synchronous belt 122 to move toward the placement plate 5. When the photovoltaic panel contacts the positioning synchronous belt 82, the photovoltaic panel can be driven by the positioning synchronous belt 82 to move until the end of the photovoltaic panel contacts the limiting guide roller 11 and stops, completing the self-test. Automatic loading action, when the detection is completed, the positioning motor 81 and the feeding motor 123 can rotate in the opposite direction to drive the feeding synchronous belt 122 to rotate clockwise to complete the automatic blanking action, that is, the rotation direction of the positioning motor 81 and the feeding motor 123 is the same. When loading, the power output ends of the feeding motor 123 and the positioning motor 81 rotate counterclockwise, and when blanking, the power output ends of the feeding motor 123 and the positioning motor 81 rotate clockwise. The positioning motor 81 and the feeding motor 123 can both use servo motors. The servo motor is a rotary actuator or a linear actuator that allows precise control of angular velocity or linear position, speed and acceleration.

[0052] In this embodiment, when adjusting the position of the photovoltaic panel, when adjusting the photovoltaic panel on the placement flat plate 5, the positioning motor 81 can drive the positioning synchronous belt 82 to rotate, so that the photovoltaic panel on the placement flat plate 5 can move towards the limiting guide roller 11, making one side of the photovoltaic panel tangent to the limiting guide roller 11, and stopping until one side edge of the photovoltaic panel is flush. Then, by rectifying one side edge of the photovoltaic panel, it is ensured that the photovoltaic panel is flat on the placement flat plate 5, effectively preventing the photovoltaic panel from being inclined on the placement flat plate 5, which is convenient for subsequent detection and alignment.

[0053] In this embodiment, it should be further described that to prevent the placement flat plate 5 from blocking the periphery of the photovoltaic panel. During the detection process, since the X-ray beam passes through the glued joint of the photovoltaic panel and shines on the light-receiving flat plate 7 to form an image. Therefore, if the bottom of the periphery of the photovoltaic panel is blocked, there will be a situation where the shadow of the blocking object image overlaps with the shadow of the bubble detection image, resulting in the inability to analyze the bubble image and thus affecting the detection accuracy. The limiting guide roller 11 and the feeding mechanism 12 can be spaced from the placement flat plate 5. When the photovoltaic panel moves, the end of the photovoltaic panel extends beyond the placement flat plate 5. The area size of the placement flat plate 5 can also be set to be smaller than the area size of the photovoltaic panel, so that the periphery of the photovoltaic panel is in a suspended state, reducing the situation where the blocking object at the glued joint around the photovoltaic panel blocks the detection beam and ensuring the detection accuracy.

[0054] In Embodiment 4, to achieve continuous automatic detection of photovoltaic panels, most existing photovoltaic panels are produced using a continuous production line during the production process. To be applicable to continuous production and continuously detect photovoltaic panels of different sizes to improve work efficiency, in this embodiment: a conveying guide rail is provided directly below the conveying plane 4, the other side of the movable crossbeam 1 faces the conveying guide rail, and a moving slider is provided on the other side of the movable crossbeam 1, making the moving slider slidably connected to the conveying guide rail. Therefore, the movable crossbeam 1 can be guided by the conveying track, and several movable crossbeams 1 can be provided. The conveying plane sequentially conveys several movable crossbeams 1 between the detection light source 6 and the light-receiving flat plate 7, which can effectively improve work efficiency, is applicable to continuous detection of multiple photovoltaic panels, and improves the scope of application and work efficiency.

[0055] In this embodiment, it should be further supplemented that a driving unit can be provided at the bottom of the movable crossbeam 1, and the power output end of the driving unit is rotatably arranged on the conveying guide rail, which is convenient for the movable crossbeam 1 to move on the conveying guide rail.

[0056] Embodiment 5, in combination with the above embodiments, this embodiment also provides a method for automatically detecting solar photovoltaic panels, which is applied to the solar photovoltaic panel automatic detection device in the above embodiments and includes the following steps: Step 1: Place the photovoltaic panel to be detected flat on the placement flat plate 5. Convey the movable crossbeam 1 through the conveying plane 4 until the placement flat plate 5 is between the detection light source 6 and the light-receiving flat plate 7. A detection station is formed between the light-emitting surface of the detection light source 6 and the light-receiving surface of the light-receiving flat plate 7. Step 2: Obtain the detection starting point coordinates of the glued joint of the photovoltaic panel. Drive the detection light source 6 to move through the light-shifting device 2, and also drive the light-receiving flat plate 7 to move through the plate-shifting device 3, so that both the light-emitting surface of the detection light source 6 and the light-receiving surface of the light-receiving flat plate 7 are aligned with the starting point coordinates of the glued joint. Step 3: During the detection process, the light-emitting surface of the detection light source 6 and the light-receiving surface of the light-receiving flat plate 7 move peripherally along the glued joint of the photovoltaic panel from the starting point coordinates, and stop moving after reaching the starting point coordinates again. Step 4: Obtain the X-ray beam image, and analyze the bubble state at the glued joint based on the obtained X-ray beam image.

[0057] For the above steps, it can be concluded that before detection, it is necessary to ensure that the photovoltaic panel on the placement flat plate 5 is between the detection light source 6 and the light-receiving flat plate 7, and it is necessary to obtain the starting point coordinates before detection, so that the detection light source 6 and the light-receiving flat plate 7 can move peripherally from the starting point coordinates, which can ensure that the X-ray beam of the detection light source 6 moves peripherally along the glued joint of the photovoltaic panel, and when the detection light source 6 moves peripherally, the light-receiving flat plate 7 can move synchronously to realize the bubble detection of the glued joint around the photovoltaic panel, effectively realizing the non-destructive bubble detection of the glued joint of the photovoltaic panel by X-ray, and realizing the all-round bubble detection of the glued joint around the photovoltaic panel.

[0058] Combined with the above embodiments, it can be concluded that X-Ray uses a cathode ray tube to generate high-energy electrons to strike a metal target. During the impact process, due to the sudden deceleration of the electrons, the kinetic energy they lose will be released in the form of X-Ray. For the positions of the photovoltaic panel that cannot be detected by the appearance method, by recording the change in the light intensity after X-Ray penetrates substances with different densities, the contrast effect generated can form an image to display the internal structure of the object to be measured, and then the problematic area inside the object to be measured can be observed without damaging the object to be measured.
