[0037] A fill light device 2 is used to supplement the light during photovoltaic glass inspection. The fill light device 2 is arranged on a base 1. The fill light device 2 includes four cylinders 21. The four cylinders 21 are divided into two groups with two as one group. A mounting arm 22 is slidably mounted on the two cylinders 21 in the same group. Two adjusting disks 23 are mounted on the mounting arm 22. An arc-shaped slide groove is arranged on the adjusting disk 23. A No. 1 shaft 24 is slidably connected between the two adjusting disks 23. The No. 1 shaft 24 is slidably connected between the arc-shaped slide grooves of the two adjusting disks 23. The No. 1 shaft 24 can slide on the two arc-shaped slide grooves. A photometric lamp 25 is connected to the outer wall of the No. 1 shaft 24. When the No. 1 shaft 24 slides, the angle of the photometric lamp 25 changes accordingly, and the staff can manually adjust the angle of the photometric lamp 25. The illumination angle is adjusted by the two light measuring lamps 25 which are axially symmetrically arranged with the mounting rod 13 as the central axis.

A second shaft 27 is rotatably mounted on the layer plate 6 through a bracket. A backlight 28 is connected to the outer wall of the second shaft 27. The light 28 is located below the two line scan cameras 14, and the backlight 28 irradiates from the bottom of the photovoltaic glass.

The outer wall of the short shaft 29 is connected to a first groove rod 210, and the end of the second shaft 27 near the first groove rod 210 is connected to a second groove rod 212. The first groove rod 210 is installed with a roller 211, and the cam 213 is installed on the cam 213. A roller is arranged on the top, and the cam 213 is slidably connected with the inner wall of the No. 1 slot rod 210 through the roller. When the cam 213 rotates, the No. 1 slot rod 210 can be driven to swing through the roller. The roller 211 is slidably connected with the inner wall of the No. 2 slot rod 212. The cam 213 rotates following the slave shaft 9 connected thereto. When the cam 213 rotates, the roller drives the No. 1 slot rod 210 to swing with the short axis 29 as the center of the circle. When the No. 1 slot rod 210 swings, the roller 211 drives the No. 2 slot rod 212 to swing. When the No. 2 slot rod 212 swings, the backlight 28 is driven to swing through the No. 2 axis 27, so that the backlight 28 can swing continuously during the detection and shooting process, so that the light keeps shaking, and the angle of the light source is changed, thereby improving the contrast of the image;By setting the fill light device 2, during the detection and shooting of the photovoltaic glass, the two light measuring lamps 25 and the backlight 28 fill light for the photovoltaic glass from three angles, improving the shooting clarity and contrast, thereby improving the accuracy of the detection result; the two light measuring lamps 25 can adjust the height and irradiation angle according to the use requirements, and the two line scanning cameras 14 can adjust the shooting angle to ensure the brightness and shooting angle requirements during the detection; the backlight 28 can be continuously swung during the detection and shooting process, so that the light source at the back of the photovoltaic glass is continuously moved, and by switching between different lighting angles, the flaws and details on the glass can be better highlighted, so that the detection system can more easily identify defects. ;

[0038] For further information, see Figure 7 - Fig. 9The centering device 3 is used to keep the photovoltaic glass in the center during transportation. The centering device 3 is arranged on the support 7. The centering device 3 includes two slides 31. The two slides 31 are slidably installed on the support 7. A push plate 32 is installed on the slide 31 through a plurality of springs. The two push plates 32 are mirror-imaged. The edge of the push plate 32 is arranged in an arc shape. When the photovoltaic glass touches the arc edge of the push plate 32 during movement, it can slide along the arc edge to the plane of the push plate 32 to avoid the corners of the photovoltaic glass and the corners of the push plate 32 from contacting each other and getting stuck. The outer wall of the short shaft 29 is connected with a curved block 39. A slider 38 is slidably installed on the mounting frame 5 near the cam 213. A rebound rod 37 is installed on the mounting frame 5 near the cam 213. The rebound rod 37 is provided with a spring and can rebound and reset by the elastic force of the spring. The rebound rod 37 is connected to the slider 38. The slider 38 contacts the arc block 39. When the arc block 39 swings to the right, it pushes the slider 38 upward by its arc surface. When the arc block 39 swings to the left, it loses the thrust on the slider 38. The slider 38 resets downward by the elastic force of the rebound rod 37. A connecting rod 310 is hinged between the slider 38 and one of the slides 31. When the slider 38 reciprocates up and down, it drives one of the slides 31 to reciprocate back and forth through the connecting rod 310. The bottom of the slide 31 is connected to the connecting frame 33. A rack rod 34 is connected to the connecting frame 33, a slide plate 35 is installed on the support 7, the slide plate 35 is located below the slave shaft 9, a gear 36 is rotatably installed on the slide plate 35, the two rack rods 34 are slidably connected to the slide plate 35, the two rack rods 34 are meshed with the gear 36, the two rack rods 34 are centrally symmetrically arranged with the gear 36 as the center, one of the rack rods 34 drives the other rack rod 34 to slide in the opposite direction by the gear 36, so that the two rack rods 34 can move in the opposite direction synchronously, and because the two rack rods 34 are respectively connected to the two slides 31 through the two connecting frames 33, the two slides 31 can also achieve synchronous reverse movement The effect is that when one of the push plates 32 pushes forward, the other push plate 32 pushes synchronously. When the photovoltaic glass tilts during the movement on the support 7 and multiple slave shafts 9, the push of the two push plates 32 can keep the photovoltaic glass moving in a centered state; through the setting of the centering device 3, the two push plates 32 can align the photovoltaic glass through synchronous and reverse back and forth pushing, maintain the neatness of the photovoltaic glass during the movement, avoid the photovoltaic glass shifting during the movement and causing incomplete local shooting, and avoid the photovoltaic glass shifting and causing the edge of the photovoltaic glass to collide with the support 7 during the movement and be damaged.

[0039] Further, see Fig.10 - Fig.12, a cleaning device 4 is used to clean dust on the surface of the photovoltaic glass. The cleaning device 4 is arranged on the support 7. The cleaning device 4 includes a third shaft 41. The third shaft 41 is rotatably installed on the support 7 through a bracket. The end of the third shaft 41 away from the motor 10 is connected to a first pulley 43, and the end of the main shaft 8 away from the motor 10 is connected to a second pulley 44. The first pulley 43 and the second pulley 44 are connected by a belt. A cleaning roller 42 is installed on the outer wall of the third shaft 41. A plurality of cleaning strips are arranged on the cleaning roller 42. The cleaning roller 42 contacts the photovoltaic glass when rotating, so that the photovoltaic glass is gradually placed on the plurality of slave shafts 9. In the process, the cleaning roller 42 and the main shaft 8 clamp the photovoltaic glass. In the middle, the dust on the surface of the photovoltaic glass is cleaned by the rotation of the cleaning roller 42 to prevent the dust on the surface of the photovoltaic glass from being misjudged as a defect point, thereby affecting the accuracy of the detection result; a collecting box 45 is installed on the support 7, and a fourth shaft 46 is slidably installed on the collecting box 45 through a bracket. The outer wall of the fourth shaft 46 is connected to a scraper 47, and the scraper 47 is in contact with the cleaning roller 42. The scraper 47 is located above the collecting box 45. The scraper 47 scrapes the dust attached to the cleaning roller 42 into the collecting box 45 through contact with the cleaning roller 42, so as to maintain the cleanliness of the cleaning roller 42. The collecting box 45 can prevent the dust on the cleaning roller 42 from falling onto the photovoltaic glass again to cause secondary pollution. The collecting box 45 A sliding rod 49 is installed on the upper slide, and a lever 410 is installed on the sliding rod 49. The outer wall of the third shaft 41 is connected to a bevel groove ring 411, and a bevel groove is set on the bevel groove ring 411. The lever 410 is slidably connected with the bevel groove of the bevel groove ring 411. A touch rod 48 is installed on the scraper 47, and the touch rod 48 contacts the sliding rod 49. When the bevel groove ring 411 rotates, the sliding rod 49 is driven to move back and forth by the cooperation of the bevel groove and the lever 410. Springs are respectively set at both ends of the scraper 47. The two springs on the scraper 47 play a booster role, so that the scraper 47 can be immediately reset by elastic force after being toggled. The sliding rod 49 drives the scraper 47 and the fourth shaft 46 through the touch rod 48. By reciprocating back and forth, the scraper 47 can increase the contact area with the cleaning roller 42 through the reciprocating movement, and further improve the cleaning effect of the scraper 47 on the cleaning roller 42; through the setting of the cleaning device 4, the cleaning roller 42 can clean the photovoltaic glass to be inspected and photographed by rotating, remove dust on the surface of the photovoltaic glass, and avoid the dust on the surface of the photovoltaic glass causing misjudgment of the detection and affecting the detection result; through the setting of the scraper 47, the scraper 47 can use its contact with the cleaning roller 42 during the reciprocating movement to scrape the dust attached to the cleaning roller 42 into the collection box 45, so as to maintain the cleanliness of the cleaning roller 42 and maintain the cleaning effect of the cleaning roller 42.

[0040] With the above structure, the working principle of this case is that after the motor 10 is started, it drives the main shaft 8 to rotate, and the main shaft 8 drives the multiple slave shafts 9 to rotate through the cooperation of multiple sprockets 11 and chains 12. The staff places the photovoltaic glass on the multiple slave shafts 9 through the mechanical arm, and the multiple slave shafts 9 drive the photovoltaic glass to move to the right through rotation. During the movement of the photovoltaic glass, two line scanning cameras 14 scan and shoot the photovoltaic glass. During the shooting process, the photovoltaic glass always maintains a uniform motion state, and there is no need to stop for shooting, thereby optimizing the beat of the entire production line. After the photovoltaic glass has completely passed and the shooting is completed, the two line scanning cameras 14 transmit the captured photos to the industrial computer, and the software is used to analyze the types of defects on the surface or inside of the glass and the individual defects. The coordinates of the defects and the preliminary size are calculated, and then the next inspection link is entered to further determine the specific size and type of the defects, so as to determine whether the photovoltaic glass is a good product. During the shooting process, two light measuring lamps 25 fill in the front of the photovoltaic glass from the upper and lower sides of the photovoltaic glass, and the backlight 28 illuminates from the bottom of the photovoltaic glass. The backlight illumination makes the defects inside the photovoltaic glass more obvious, improves the contrast of the photos taken, and thus improves the detection efficiency; the staff can loosen the two adjustment wires 26 so that the mounting arm 22 can slide up and down on the two cylinders 21, so as to adjust the height of the light measuring lamp 25, and tighten the adjustment wire 26 after the adjustment is completed. 4 can slide on the two adjustment disks 23, so that the staff can manually adjust the irradiation angle of the light metering lamp 25 to meet different usage requirements, and the mounting rod 13 can be rotated and adjusted to adjust the shooting angles of the two line scanning cameras 14; the cam 213 rotates following the slave shaft 9 connected thereto, and when the cam 213 rotates, the roller drives the first slot rod 210 to swing with the short axis 29 as the center of the circle, and when the first slot rod 210 swings, the roller 211 drives the second slot rod 212 to swing, and when the second slot rod 212 swings, the backlight 28 is driven to swing through the second shaft 27, so that the backlight 28 can swing continuously during the detection and shooting process, so that the light is constantly shaking, and the angle of the light source is changed, thereby improving the contrast of the image; The layer plate 6 can be used to place relevant tools and play a storage role; through the setting of the fill light device 2, during the detection and shooting of the photovoltaic glass, the two light metering lights 25 and the backlight 28 can fill light for the photovoltaic glass from three angles to improve the shooting clarity and contrast, thereby improving the accuracy of the detection results; the two light metering lights 25 can adjust the height and illumination angle according to the use requirements, and the two line scanning cameras 14 can adjust the shooting angle to ensure the brightness and shooting angle requirements during the detection; the backlight 28 can continuously swing during the detection and shooting process, so that the light source on the back of the photovoltaic glass is constantly moving, and by switching between different lighting angles, it can better highlight the flaws and details on the glass, so that the detection system can more easily identify defects.

[0041] The short shaft 29 reciprocates with the swing of the No. 1 slot rod 210, and the short shaft 29 drives the arc block 39 to swing back and forth when it rotates. Due to the limiting effect of the mounting frame 5 on the slider 38, the arc block 39 uses its arc surface to push the slider 38 upward when it swings to the right, and loses the thrust on the slider 38 when it swings to the left. The slider 38 is reset downward by the elastic force of the rebound rod 37. The slider 38 maintains contact with the arc block 39 by continuously applying pressure to the arc block 39, so that the arc block 39 drives the slider 38 to move up and down through the cooperation with the rebound rod 37 during the reciprocating swing process. When the slider 38 reciprocates up and down, it drives one of the slides 31 to move back and forth through the connecting rod 310. When one of the rack rods 34 slides on the slide rail plate 35, one of the rack rods 34 drives the other rack rod 34 to slide in the opposite direction using the gear 36, thereby achieving the effect that the two rack rods 34 can move in the opposite direction synchronously. The rack rod 34 is connected to the two slides 31 through the connecting frame 33, so that when one of the slides 31 moves back and forth, the other slide 31 moves back and forth synchronously, and the movement directions of the two slides 31 are opposite. When the slide 31 moves, the push plate 32 is driven to move synchronously by multiple springs, so that the two push plates 32 can continuously and repeatedly move in the direction close to the photovoltaic glass. When the photovoltaic glass tilts during the movement on the support 7 and multiple slave shafts 9, the push of the two push plates 32 can keep the photovoltaic glass moving in a centered state; through the setting of the centering device 3, the two push plates 32 can align the photovoltaic glass by synchronously and reversely pushing back and forth, so as to maintain the neatness of the photovoltaic glass during the movement, avoid the photovoltaic glass from shifting during the movement and causing incomplete local shooting, and avoid the photovoltaic glass from shifting and causing the edge of the photovoltaic glass to collide with the support 7 during the movement and be damaged.

[0042] When the main shaft 8 rotates, the main shaft 8 drives the second pulley 44 to rotate, the second pulley 44 drives the first pulley 43 to rotate through the belt, the first pulley 43 drives the third shaft 41 to rotate, and the third shaft 41 drives the cleaning roller 42 to rotate. The cleaning roller 42 contacts the photovoltaic glass during rotation, so that the photovoltaic glass is gradually placed on multiple slave shafts 9. In the process, the dust on the surface is cleaned by the cleaning roller 42 to avoid the dust on the surface of the photovoltaic glass being misjudged as a defect point, thereby affecting the accuracy of the detection result; when the cleaning roller 42 rotates, the scraper 47 scrapes the dust attached to the cleaning roller 42 into the collecting box 45 through contact with the cleaning roller 42, so as to maintain the cleanliness of the cleaning roller 42 and avoid secondary pollution of the photovoltaic glass caused by too much dust attached to the surface of the cleaning roller 42. When the third shaft 41 rotates, it drives the inclined groove ring 411 to rotate. When the inclined groove ring 411 rotates, the inclined groove and the dial are used to clean the dust on the surface of the photovoltaic glass. The cooperation of rod 410 drives the sliding rod 49 to move back and forth, and the sliding rod 49 drives the scraper 47 and the fourth shaft 46 to move back and forth through the touch rod 48. The two springs on the scraper 47 act as a booster.
