Description

Technical Field

[0001] The present invention belongs to the technical field of glass detection, and in particular to a photovoltaic glass surface defect detection device and a detection method. Background Art

[0002] Photovoltaic glass is one of the solar cell components. It is a component that can be used for solar cells by evenly coating a layer of transparent conductive oxide film on the glass through physical or chemical coating methods. For solar panels, while improving the photoelectric conversion efficiency of the battery, it is also extremely important to improve the transmittance of the photovoltaic glass on the upper surface of the solar panel so that more sunlight can be received by the solar panel.

[0003] A patent with announcement number CN213813401U discloses a surface defect inspection auxiliary device in the production of photovoltaic glass coating, which solves the shortcomings of incomplete detection and large errors in the prior art. It includes a working platform, a support frame, a light source and support legs. The light source is fixed to the top of the working platform through the support frame. Cleaning components are provided on both sides of the top of the working platform. The support legs are respectively fixed on both sides of the bottom of the angle adjustment component. The photovoltaic glass can be cleaned before detection to prevent the attachments on its surface from affecting its detection. Moreover, the detection device can only polish the edges of the glass and cannot clean and detect the peeled surface scratches.

[0004] In the current existing technology, in order to increase the transmittance of light, the surface of the existing photovoltaic glass needs to be extremely smooth and transmittance. If scratches appear on the surface of the photovoltaic glass, the inside of the scratches will be filled with impurities and dust over time. These scratches will affect the transmittance of the photovoltaic glass. The existing detection device uses light to be reflected multiple times on the surface of the photovoltaic glass, and uses the refractive index generated by the reflection of light to effectively detect the scratches on the surface of the photovoltaic glass. However, the reflection of light will illuminate the scratches on the surface of the photovoltaic glass, resulting in a transmittance that is too high, so that the camera lens cannot effectively detect and process the scratches.

[0023] 2. The photovoltaic glass surface defect detection device and detection method described in the present invention, when the scratches on the top surface of the photovoltaic glass are filled with light calcium carbonate white powder, with the push of the staggered anti-skid rollers, the photovoltaic glass will move section by section at the vertical bottom of the camera lens unit group, and cooperate with the swing arm to swing the illumination lamp back and forth left and right, and the illumination lamp light source will pass through the photovoltaic glass to illuminate the surface of the transmission light source belt, and then re-irradiate the surface of the photovoltaic glass by reflecting the transmission light source belt. When the light passes through the surface of the photovoltaic glass, the light will leave a shadow dark part on the surface of the photovoltaic glass under the obstruction of the light calcium carbonate white powder. As the light source continues to change, the dark part will also change accordingly, making it more convenient for the camera lens unit group to illuminate and detect the dark part on the end surface of the photovoltaic glass, so as to achieve the effect of utilizing the light calcium carbonate white powder to block the light, so that the light cannot pass through the light calcium carbonate white powder on the top surface of the photovoltaic glass, and then form a shadow dark part on the surface of the photovoltaic glass, which is convenient for the subsequent camera lens unit group to illuminate and detect the photovoltaic glass.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Example 1

[0037] like Figures 1 to 8As shown, a photovoltaic glass surface defect detection device according to an embodiment of the present invention comprises a photovoltaic glass detection platform 11 and a photovoltaic glass 12 movably sleeved on the inner wall surface of the top of the photovoltaic glass detection platform 11, a semicircular sleeve 13 detachably mounted on the middle position of the top of the photovoltaic glass detection platform 11, a motor 15 fixedly mounted on the top surface of the photovoltaic glass detection platform 11 and located at the left edge position of the semicircular sleeve 13, a semicircular sealing cover 14 fixedly mounted on the top surface of the photovoltaic glass detection platform 11 and located at the right edge position of the semicircular sleeve 13, a motor 15 fixedly mounted on the outer surface of the photovoltaic glass detection platform 11, staggered anti-skid rollers 112 movably adjusted on the outer surface of the photovoltaic glass 12 are symmetrically mounted on the inner wall surfaces on both sides of the top of the photovoltaic glass detection platform 11, and a transmission light source belt 111 arranged on the bottom edge position of the semicircular sleeve 13 is fixedly mounted on the outer surface of the photovoltaic glass detection platform 11 and located in the middle position; A transmission rod 151 is movably connected to the outer surface of the glass inspection platform 11 and is located at the edge positions on both sides of the motor 15, a transmission crawler 152 is movably connected to the outer surface of the output end of the motor 15 and the outer surface of the transmission rod 151, a push rod 153 is movably connected to the outer surface of one end of the transmission rod 151, a limiting column 154 is fixedly connected to the top surface of the photovoltaic glass inspection platform 11 and is located at the edge positions on both sides of the transmission rod 151, a swing table 156 is movably connected to the outer surface of the limiting column 154, the other end of the push rod 153 is movably connected to the outer surface of the swing table 156, a blanking strip 158 is fixedly connected to the bottom surface of the swing table 156 and is located in the middle position, a fine screening plate 159 is arranged on the inner bottom edge position of the blanking strip 158, a soft scraping strip 1510 that is slidably overlapped on the outer surface of the photovoltaic glass 12 is arranged on the bottom surface of the blanking strip 158, and the interior of the swing table 156 is filled with light calcium carbonate white powder.

[0038] The photovoltaic glass 12 is overlapped on the inner wall of the photovoltaic glass inspection platform 11, and the staggered anti-skid rollers 112 on the inner wall of the photovoltaic glass inspection platform 11 are staggered and overlapped on the upper and lower surfaces of the photovoltaic glass 12, and the photovoltaic glass 12 is moved to the rear end of the photovoltaic glass inspection platform 11. When the top surface of the photovoltaic glass 12 moves from the bottom edge position of the swing table 156 in sections, the motor 15 drives the transmission track 152 to drive the transmission rod 15 on the outer surface of the photovoltaic glass inspection platform 11 1 is rotated, and while the transmission rod 151 is rotating, it cooperates with the push rod 153 on the outer surface of the transmission rod 151 to move up and down, thereby pushing the swinging table 156 at one end of the push rod 153 up and down on the top surface of the photovoltaic glass inspection platform 11. When the swinging table 156 moves up and down, it cooperates with the limit column 154 to limit the position of the swinging table 156. When the swinging table 156 moves up and down, it will produce slight vibration every time it moves up and down, and when the swinging table 156 vibrates, it will The light calcium carbonate white powder inside the plate 156 is vibrated and scattered into the inside of the blanking strip 158. The internal space of the blanking strip 158 is used to limit the capacity of the light calcium carbonate white powder, and then the light calcium carbonate white powder is evenly scattered through the fine screening plate 159 at the bottom inner side of the blanking strip 158. The scattered light calcium carbonate white powder will adhere to the top surface of the photovoltaic glass 12, and at the same time, the soft scraper 1510 on the bottom surface of the blanking strip 158 is used to scrape and smooth the light calcium carbonate white powder on the top surface of the photovoltaic glass 12. After the treatment, light calcium carbonate white powder forms a thin layer on the top surface of the photovoltaic glass 12. At the same time, the light calcium carbonate white powder on the top surface of the photovoltaic glass 12 is scraped by the soft scraper 1510, so that a part of the light calcium carbonate white powder penetrates into the scratches on the surface of the photovoltaic glass 12. The scratches filled with light calcium carbonate white powder are not light-transmissive. Under the illumination of light source, the shadow of the scratch on the top surface of the photovoltaic glass 12 will be greatly magnified, which is easier to detect under the illumination of the camera.

[0039] like Figure 1-Figure 2 and Figure 7 - Figure 8 As shown, a camera lens unit group 131 is fixedly installed on the top inner wall of the semicircular shell 13, and swing arms 132 are swingably connected to the inner walls of both sides of the semicircular shell 13. The output end of the swing arm 132 is fixedly connected to a lighting lamp 133 that is movably sleeved on the inner wall of the semicircular shell 13.

[0040] As an embodiment of the present invention, after the scratches on the top surface of the photovoltaic glass 12 are filled with light calcium carbonate white powder, the photovoltaic glass 12 will move section by section at the vertical bottom of the camera lens unit group 131 under the push of the staggered anti-skid rollers 112, and the swing arm 132 will swing the illumination lamp 133 back and forth. The light source of the illumination lamp 133 will pass through the photovoltaic glass 12 and illuminate the surface of the transmission light source belt 111, and then be re-illuminated to the surface of the photovoltaic glass 12 by the reflection of the transmission light source belt 111. When the light passes through the surface of the photovoltaic glass 12, the light When blocked by the light calcium carbonate white powder, the light will leave a dark shadow on the surface of the photovoltaic glass 12. As the light source continues to change, the dark part will also change accordingly, making it more convenient for the camera lens unit group 131 to irradiate and detect the dark part on the end surface of the photovoltaic glass 12. The light calcium carbonate white powder is used to block the light, so that the light cannot pass through the light calcium carbonate white powder on the top surface of the photovoltaic glass 12, thereby forming a dark shadow on the surface of the photovoltaic glass 12, which facilitates the subsequent camera lens unit group 131 to irradiate and detect the photovoltaic glass 12.

[0041] like Figures 1 to 6 As shown, an elastic buffer wire 155 arranged on the outer surface of the top of the photovoltaic glass inspection platform 11 is fixedly connected to the bottom surface of the swinging table 156, a guide chute 157 is arranged on the inner wall surface of the swinging table 156, a sealing cover is arranged on the top surface of the swinging table 156, a blower 141 fixedly installed on the outer surface of the photovoltaic glass inspection platform 11 is arranged on the back side of the semicircular sealing cover 14, an injection pipe 143 arranged on the outer surface of the top of the photovoltaic glass inspection platform 11 is fixedly connected to the output end of the blower 141, an injection head 144 arranged on the outer surface of the bottom of the semicircular sealing cover 14 is fixedly connected to the outer surface of the injection pipe 143, and an air intake pipe 142 arranged on the outer surface of the top of the semicircular sealing cover 14 is fixedly connected to the input end of the blower 141.

[0042] As an embodiment of the present invention, after the photovoltaic glass 12 is inspected, the photovoltaic glass 12 will move into the interior of the semicircular sealing cover 14, and the staggered anti-skid rollers 112 will stop moving the photovoltaic glass 12. At this time, the blower 141 will be used to infuse gas into the interior of the jet tube 143, and then the jet head 144 on the outer surface of the jet tube 143 will be used to blow the light calcium carbonate white powder on the top surface of the photovoltaic glass 12 at an inclined angle. The gases blown from both sides at the same time will offset the light calcium carbonate white powder on the top surface of the photovoltaic glass 12. After the offset, The light calcium carbonate white powder will be drained upward, so that the light calcium carbonate white powder floats high in the internal space of the semicircular sealing cover 14. At this time, the blower 141 absorbs the gas inside the suction pipe 142, and the light calcium carbonate white powder scattered inside the semicircular sealing cover 14 is sucked back and recovered, thereby achieving the effect of using the air flow to offset at an inclined angle. Under the gas offset, the light calcium carbonate white powder remaining on the top surface of the photovoltaic glass 12 will be blown away, which is convenient for the subsequent recovery of the light calcium carbonate white powder.

[0043] Example 2

[0044] like Fig. 9 As shown, a photovoltaic glass surface defect detection method comprises the following steps:

[0045] S1. Place the photovoltaic glass on the surface of the testing table, use the conveying wheel to alternately bond the photovoltaic glass up and down, and clamp the photovoltaic glass to a defined position;

[0046] S2, evenly scattering light calcium carbonate white powder on the top surface of the photovoltaic glass, so that the light calcium carbonate white powder forms a thin layer on the surface of the photovoltaic glass;

[0047] S3. When the light calcium carbonate powder encounters the scratch groove on the surface of the photovoltaic glass, the light calcium carbonate powder on the surface of the photovoltaic glass will sink into the scratch groove, thereby forming a dent on the surface of the photovoltaic glass;

[0048] S4. The photovoltaic glass passes through the inspection station on the conveyor belt at a constant speed. Three groups of light sources are used to illuminate the passing photovoltaic glass at the same time. The camera will take defect images of the passing photovoltaic glass. This process is carried out step by step as the glass moves until the photovoltaic glass leaves the inspection station. The visual camera completes the capture of the defect image of the entire photovoltaic glass. At the same time, the image processing system detects and classifies defects in the image, and marks the photovoltaic glass ID and the defect situation of this photovoltaic glass.

[0049] Working principle: When the top surface of the photovoltaic glass 12 moves section by section from the bottom edge of the swinging table 156, while the transmission rod 151 rotates, the swinging table 156 at one end of the push rod 153 is pushed up and down on the top surface of the photovoltaic glass inspection platform 11. Every time the swinging table 156 moves up and down, it will produce a slight vibration, which will vibrate the light calcium carbonate white powder inside the swinging table 156 into the inside of the blanking strip 158, and then the light calcium carbonate white powder will be evenly scattered through the fine screening plate 159 at the bottom of the inner side of the blanking strip 158. At the same time, the soft scraping strip 1510 on the bottom surface of the blanking strip 158 is used to scrape and smooth the light calcium carbonate white powder on the top surface of the photovoltaic glass 12. At the same time, the light calcium carbonate white powder on the top surface of the photovoltaic glass 12 is scraped by the soft scraping strip 1510, so that a part of the light calcium carbonate white powder penetrates into the scratches on the surface of the photovoltaic glass 12. The scratches filled with light calcium carbonate white powder will not be light-transmissive. Under the illumination of the light source, the shadow of the scratch on the top surface of the photovoltaic glass 12 will be greatly magnified, and it will be easier to detect under the illumination of the camera.

[0050] When the scratches on the top surface of the photovoltaic glass 12 are filled with light calcium carbonate white powder, the photovoltaic glass 12 will move section by section at the vertical bottom of the camera lens unit group 131 under the push of the staggered anti-skid rollers 112, and the swing arm 132 will swing the light lamp 133 back and forth. The light source of the light lamp 133 will pass through the photovoltaic glass 12 and shine on the surface of the transmission light source belt 111, and then reflect back to the surface of the photovoltaic glass 12 by the transmission light source belt 111. When the light passes through the surface of the photovoltaic glass 12, the light will be reflected on the light calcium carbonate. Under the obstruction of the white powder, the light will leave a shadow dark part on the surface of the photovoltaic glass 12. As the light source changes continuously, the dark part will also change accordingly, making it more convenient for the camera lens unit group 131 to irradiate and detect the dark part on the end surface of the photovoltaic glass 12, thereby achieving the effect of using the light calcium carbonate white powder to block the light, so that the light cannot pass through the light calcium carbonate white powder on the top surface of the photovoltaic glass 12, thereby forming a shadow dark part on the surface of the photovoltaic glass 12, making it convenient for the subsequent camera lens unit group 131 to irradiate and detect the photovoltaic glass 12;

[0051] When the photovoltaic glass 12 is inspected, it will move into the interior of the semicircular sealing cover 14, and cooperate with the staggered anti-skid rollers 112 to stop moving the photovoltaic glass 12. At this time, the blower 141 is used to inject gas into the interior of the jet tube 143, and then the jet head 144 on the outer surface of the jet tube 143 is used to blow the light calcium carbonate white powder on the top surface of the photovoltaic glass 12 at an inclined angle. The gas blown from both sides at the same time will offset the light calcium carbonate white powder on the top surface of the photovoltaic glass 12. The white powder will drain the light calcium carbonate white powder upward, so that the light calcium carbonate white powder floats high in the internal space of the semicircular sealing cover 14. At this time, the blower 141 absorbs the gas inside the suction pipe 142, and the light calcium carbonate white powder floating inside the semicircular sealing cover 14 is sucked back and recovered, thereby achieving the effect of using the air flow to offset at an inclined angle. Under the offset of the gas, the light calcium carbonate white powder remaining on the top surface of the photovoltaic glass 12 will be blown away, which is convenient for the subsequent recovery of the light calcium carbonate white powder.

Place the photovoltaic glass on the surface of the testing table, use the conveying wheel to alternately bond the photovoltaic glass up and down, and clamp the photovoltaic glass to a defined position; S2, evenly scattering light calcium carbonate white powder on the top surface of the photovoltaic glass, so that the light calcium carbonate white powder forms a thin layer on the surface of the photovoltaic glass; S3. When the light calcium carbonate powder encounters the scratch groove on the surface of the photovoltaic glass, the light calcium carbonate powder on the surface of the photovoltaic glass will sink into the scratch groove, thereby forming a dent on the surface of the photovoltaic glass; S4. The photovoltaic glass passes through the inspection station on the conveyor belt at a constant speed. Three groups of light sources are used to illuminate the passing photovoltaic glass at the same time. The camera will take defect images of the passing photovoltaic glass. This process is carried out step by step as the glass moves until the photovoltaic glass leaves the inspection station. The visual camera completes the capture of the defect image of the entire photovoltaic glass. At the same time, the image processing system detects and classifies defects in the image, and marks the photovoltaic glass ID and the defect situation of this photovoltaic glass.
