Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic support detection, and specifically to a quality detection device for photovoltaic supports based on machine vision. Background Art

[0002] As is well known, after the production and processing of photovoltaic supports, various profiles will be assembled into supports at the power generation site and installed with equipment such as photovoltaic panels. Although these devices can perform quality inspections on the appearance and strength of individual profiles at the processing site, after assembly, the installation levels and inclinations of the same set of supports are consistent, and it is difficult to ensure the tolerance requirements at the joints. It can only be detected by manual visual inspection. This method not only has low efficiency but also is difficult to detect parts that do not meet the tolerance requirements.

[0003] When detecting the quality of finished photovoltaic supports, detection devices can be used. The problems existing in the prior art are as follows: When visually inspecting the assembled photovoltaic supports at the power generation site, most of them are limited by the flatness of the terrain and the allowable equipment installation space in the environment. Usually, large-volume devices are also difficult to require and detect the installation levels and inclinations between finished supports and the tolerance requirements at the joints on site;

[0004] Based on the above-mentioned problems, we found that it is difficult for the prior art to avoid the above problems simultaneously in the quality inspection of the on-site assembly of photovoltaic supports. Therefore, we propose a machine vision-based photovoltaic support quality detection device that can be easily carried or disassembled and installed, can be installed without being on the ground to avoid the inconsistencies of different terrains, occupies less space, and can collect images of the assembly quality of photovoltaic supports as the basis for machine vision quality inspection. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides a quality detection device for photovoltaic supports based on machine vision, which has the advantages of being easy to carry or disassemble and install, can be installed without being on the ground to avoid the inconsistencies of different terrains, occupies less space, and can collect images of the assembly quality of photovoltaic supports as the basis for machine vision quality inspection.

[0010] By adopting the above technical solutions, by setting the mounting hook in cooperation with the folding rod, the mounting hook can facilitate the direct mounting of the folding rod on the cross beam on the back of the photovoltaic bracket, so as to avoid the influence of the ground flatness and the like when the structure is installed on the ground. The folding rod can also be folded and placed or inserted and assembled as required, so as to facilitate carrying or extending its own length as the support position of the structure. The provided sliding sleeve can facilitate sliding along the outside of the folding rod, and the adjustment frame can adjust the vertical height, horizontal position and elevation angle of the collection component in cooperation with the first electric cylinder, so as to facilitate image acquisition from different positions as the basis for machine vision quality inspection. The provided collection component is used to directly collect the image information of the photovoltaic bracket through the image acquisition camera. Since there are multiple image acquisition cameras, image acquisition can be carried out from multiple positions on the basis of reducing image acquisition dead angles, so as to avoid misjudgment of the machine vision quality inspection system, such as data such as the tolerance of the installation joint position, the relative horizontal and vertical height differences between the brackets. The provided adapter frame is used to connect the collection component and the compensation frame. The provided second electric cylinder cooperates with the push frame to facilitate pushing and pulling the sliding frame to slide along the outside of the hollow cylinder. While sliding, the sliding frame will push and pull the transmission frame to make the transmission frame apply a pushing or pulling force to the arc-shaped frame, so as to cause an angular offset of the arc-shaped frame along the hollow cylinder, so as to facilitate adjusting the acquisition angle of the image acquisition camera as required.

[0011] The present invention is further provided as: A transmission frame is rotatably connected to the side of the arc-shaped frame away from the image acquisition camera, and the side of the transmission frame close to the sliding frame is rotatably connected to the sliding frame.

[0012] By adopting the above technical solutions, by setting the transmission frame to connect the sliding frame and the arc-shaped frame and serve as the basis for applying a pushing or pulling force during processing, the transmission of the structure is made more reasonable.

[0013] The present invention is further configured as follows: the folding rod includes a plurality of rod bodies, the rod body is configured as a hollow portion, a plug-in portion is fixedly connected to the left side of the rod body, a rubber band is fixedly connected to the inner side of the rod body, and the rod bodies are movably connected to each other through the rubber band.

[0014] By adopting the above technical solution, a plurality of rod bodies can be plugged into each other through the plug-in part to facilitate the rapid disassembly and assembly of the folding rod. The elastic rope is used to ensure that the multiple rod bodies are always in a relatively strung-together state before and after the plug-in, so as to reduce the time required for personnel to sort the rod bodies when assembling them.

[0016] By adopting the above technical solution, the hook body can be directly hung on the outside of the photovoltaic bracket beam by setting it. When it needs to be fixed, the screw rod can be moved along the hook body by rotating it until it is pressed against the surface of the photovoltaic bracket beam by the pressure pad to fix the relative position of the hook body to avoid displacement or shaking when the structure moves. The outer sleeve is used to be sleeved on the rod body so that the rod body can be reasonably suspended on the periphery of the photovoltaic bracket with a smaller occupied space.

[0017] The present invention is further configured as follows: the sliding sleeve includes a sliding frame, the top of the sliding frame is slidably connected to a connecting rod, the outer side of the connecting rod is sleeved with a spring, the bottom of the connecting rod is fixedly connected to a wheel frame, the inner side of the wheel frame is rotatably connected to two wheel axles, the outer side of the wheel axle is fixedly connected to a roller, the outer side of the wheel frame is fixedly connected to a control motor, and the output end of the control motor is fixedly connected to the left wheel axle.

[0018] By adopting the above technical solution, by setting a slide to cooperate with the connecting rod and the spring, the wheel frame can always keep the roller on the outside of the wheel axle pressed against the top groove of the rod body under the pressure of the spring. When the motor is controlled to drive the wheel axle and the roller connected to it to rotate, the friction between the roller and the rod body is large due to the pressure, so the wheel frame and the external slide connected to it will be driven to move along the rod body together.

[0019] The present invention is further configured as follows: the adjustment frame includes a bent frame, the inner side of the bent frame is fixedly connected with meshing teeth, the inner side of the bent frame is fixedly connected with a turning bar, the inner side of the turning bar is rotatably connected with a folding frame, and the bottom of the folding frame is fixedly connected to the connecting frame.

[0020] With the above technical solution, by setting the bent frame to cooperate with the meshing pool, the folding frame can rotate along the rotating bar and the bent frame to adjust the pitching angle of the bottom acquisition component.

[0022] With the above technical solution, by setting the gear to cooperate with the meshing teeth, when the control motor drives the gear to rotate forward and backward on the outer side of the folding frame, the gear meshes with different meshing teeth to drive the folding frame to rotate and tilt.

[0024] With the above technical solution, by setting the transmission belt wheels to cooperate with the transmission belt, when a single wheel shaft is driven to rotate, the two wheel shafts can rotate synchronously to reasonably drive the structure, and the limiting wheel is stuck in the bottom groove of the rod body to limit the movement and installation of the structure.

[0025] The present invention is further configured as: an anti-collision frame is fixedly connected to the rear side of the first electric cylinder, and a supplementary light is fixedly connected to the rear side of the anti-collision frame.

[0026] With the above technical solution, by setting the anti-collision frame, the image acquisition camera can be protected, and as the installation position of the supplementary light, the supplementary light can supplement light and illuminate the acquisition position when the ambient light is poor or the light is blocked by the photovoltaic panel and it is difficult to perform image acquisition.

[0027] The present invention is further configured as: a rotating frame is fixedly connected to the outer side of the hollow cylinder, the inner side of the rotating frame is rotatably connected to the arc-shaped frame, rotating blocks are rotatably connected to the outer sides of the sliding frame and the outer side of the arc-shaped frame, and both the sliding frame and the arc-shaped frame are rotatably connected to the transmission frame through the rotating blocks.

The folding rod can also be folded and placed or inserted and assembled as needed, so as to facilitate carrying or extending its own length as the support position of the structure. The set sliding sleeve can facilitate sliding along the outer side of the folding rod, and in cooperation with the first electric cylinder adjustment frame, it can adjust the vertical height, horizontal position and elevation angle of the acquisition component, so as to facilitate image acquisition from different positions as the basis for machine vision quality inspection.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A first electric cylinder 4 is fixedly connected to the outside of the sliding sleeve 3. The telescopic end of the first electric cylinder 4 is fixedly connected to a compensation frame 5. An adjustment frame 6 is provided on the right side of the compensation frame 5. The top of the adjustment frame 6 is fixedly connected to the compensation frame 5. The bottom of the adjustment frame 6 is fixedly connected to an acquisition component 7. By setting the hanging hook 2 in cooperation with the folding rod 1, the hanging hook 2 can facilitate the direct hanging and installation of the folding rod 1 on the cross beam on the back of the photovoltaic bracket, so as to avoid the influence of factors such as the ground flatness when the structure is installed on the ground. The folding rod 1 can also be folded and placed or inserted and assembled as needed, so as to facilitate carrying or extending its own length as the support position of the structure. The provided sliding sleeve 3 can facilitate sliding along the outside of the folding rod 1, and the adjustment frame 6 can adjust the vertical height, horizontal position and elevation angle of the acquisition component 7 in cooperation with the first electric cylinder 4, so as to facilitate image acquisition from different positions as the basis for machine vision quality inspection.

[0045] Among them, the folding rod 1 includes a plurality of rod bodies 101. The rod body 101 is provided with a hollow part. A plugging part 102 is fixedly connected to the left side of the rod body 101. An elastic cord 103 is fixedly connected to the inner side of the rod body 101. The rod bodies 101 are movably connected by the elastic cord 103. By arranging a plurality of rod bodies 101, they can be plugged into each other through the plugging part 102 to facilitate the quick disassembly and assembly of the folding rod 1. The arranged elastic cord 103 is used to keep the plurality of rod bodies 101 in a relatively strung-up state before and after plugging, so as to reduce the time spent by personnel in sorting when assembling the rod bodies 101. The hanging hook 2 includes a hook body 201. The hook body 201 is clamped on the outside of the cross beam of the photovoltaic bracket. A screw rod 202 is threadedly connected to the inner side of the hook body 201. A pressing pad 203 is rotatably connected to the side of the screw rod 202 close to the cross beam of the photovoltaic bracket. A jacket 204 is rotatably connected to the bottom of the hook body 201. The jacket 204 is slidably connected to the outside of the rod body 101. By arranging the hook body 201, it can be directly hung on the outside of the cross beam of the photovoltaic bracket. When fixing is required, the screw rod 202 can be rotated to make the screw rod 202 displace along the hook body 201 until it presses against the surface of the cross beam of the photovoltaic bracket through the pressing pad 203 to fix the relative position of the hook body 201 and prevent displacement or shaking when the structure moves. The arranged jacket 204 is used to sleeve with the rod body 101 so that the rod body 101 can be reasonably suspended outside the photovoltaic bracket with a small occupied space. The sliding sleeve 3 includes a sliding frame 31. A connecting rod 32 is slidably connected to the top of the sliding frame 31. A spring 33 is sleeved on the outside of the connecting rod 32. A wheel frame 36 is fixedly connected to the bottom of the connecting rod 32. Two wheel shafts 37 are rotatably connected to the inside of the wheel frame 36. A roller 34 is fixedly connected to the outside of the wheel shaft 37. A control motor 35 is fixedly connected to the outside of the wheel frame 36. The output end of the control motor 35 is fixedly connected to the left wheel shaft 37. By arranging the sliding frame 31 in cooperation with the connecting rod 32 and the spring 33, the wheel frame 36 can always make the roller 34 on the outside of the wheel shaft 37 press against the top groove of the rod body 101 under the pressing of the spring 33. When the control motor 35 drives the wheel shaft 37 and the roller 34 connected thereto to rotate, since the friction between the roller 34 and the rod body 101 under pressure is large, the connected wheel frame 36 and the external sliding frame 31 will be driven to displace along the rod body 101 together. The adjustment frame 6 includes a bent frame 61. A meshing tooth 62 is fixedly connected to the inside of the bent frame 61. A rotating bar 63 is fixedly connected to the inside of the bent frame 61. A folding frame 64 is rotatably connected to the inside of the rotating bar 63. The bottom of the folding frame 64 is fixedly connected to the connecting frame 71. By arranging the bent frame 61 in cooperation with the meshing pool, the folding frame 64 can rotate along the rotating bar 63 and the bent frame 61 to adjust the pitching angle of the bottom collection component 7. A gear 65 is rotatably connected to the inside of the front side of the folding frame 64. The outside of the gear 65 is meshed and connected with the meshing tooth 62. A control motor 66 is fixedly connected to the left side of the folding frame 64. The output end of the control motor 66 penetrates through the folding frame 64 and is fixedly connected to the gear 65.By setting the gear 65 to engage with the meshing teeth 62, when the control motor 66 drives the gear 65 to rotate forward and backward on the outside of the folding frame 64, the gear 65 meshes with different meshing teeth 62 to drive the folding frame 64 to rotate and tilt. Fixed connection with a transmission pulley is provided on the outside of both of the two axle shafts 37, and the two transmission pulleys are connected by a transmission belt. The inside of the sliding frame 31 is rotatably connected with a limiting wheel 8, and the limiting wheel 8 is used in cooperation with the bottom of the rod body 101. By setting the transmission pulley and the transmission belt, when a single axle shaft 37 is driven to rotate, the two axle shafts 37 can rotate synchronously to reasonably drive the structure. The limiting wheel 8 is stuck in the bottom groove of the rod body 101, which can limit the movement and installation of the structure.

[0046] The working principle of this embodiment: First, the rod bodies 101 of the folding rod 1 are inserted into each other through the insertion parts 102 in cooperation with the rubber band 103. The hook body 201 of the hanging hook 2 is clamped on the outside of the cross beam on the back of the photovoltaic bracket. Rotate the screw 202 inside the hanging hook 2 to make the pressing pad 203 tightly press on the surface of the photovoltaic bracket cross beam to fix the position of the hook body 201 and prevent displacement or shaking. At this time, the rod body 101 is rotatably connected to the bottom of the hook body 201 through the outer sleeve 204 and is reasonably suspended on the periphery of the photovoltaic bracket. The sliding frame 31 of the sliding sleeve 3 is connected to the bottom wheel frame 36 through the connecting rod 32 and the spring 33 at the top, so that the roller 34 is always pressed against the top groove of the rod body 101 under the action of the spring 33. Start the control motor 35, and its output drives the left axle shaft 37 to rotate. The left axle shaft 37 drives the right axle shaft 37 to rotate synchronously through the transmission pulley and the transmission belt, driving the roller 34 to roll on the top of the rod body 101, thereby driving the sliding frame 31 and the structures connected thereto, such as the first electric cylinder 4, to move along the rod body 101 to adjust the horizontal position of the acquisition component 7. Start the control motor 66 on the left side of the folding frame 64, and its output drives the gear 65 to rotate. The gear 65 meshes with the meshing teeth 62 inside the bent frame 61, causing the folding frame 64 to rotate along the rotating bar 63 and the bent frame 61, and then adjusting the pitching angle of the bottom acquisition component 7. By the telescopic movement of the first electric cylinder 4, the vertical height of the compensation frame 5 and the connected adjustment frame 6 and the acquisition component 7 is adjusted to adjust the acquisition component 7 from different positions to realize image acquisition of different parts of the photovoltaic bracket and provide basic data for machine vision quality inspection.

[0047] Embodiment 2

[0048] Reference Figures 1-6, A quality inspection device for photovoltaic brackets based on machine vision further includes a collection component 7. Among them, the collection component 7 includes a connection frame 71. The bottom of the connection frame 71 is fixedly connected with an empty cylinder 72. The inner side of the empty cylinder 72 is fixedly connected with a second electric cylinder 73. The telescopic end of the second electric cylinder 73 is fixedly connected with a push frame 74. The rear side of the push frame 74 is fixedly connected with a sliding frame 75. The inner side of the sliding frame 75 is slidably connected with the empty cylinder 72. The outer side of the empty cylinder 72 is rotatably connected with an arc-shaped frame 76. The outer side of the arc-shaped frame 76 is fixedly connected with an image acquisition camera 77. The provided collection component 7 is used to directly collect the image information of the photovoltaic bracket through the image acquisition camera 77. Since there are multiple image acquisition cameras 77, it is possible to collect images from multiple positions while reducing the image acquisition dead angle to avoid misjudgment of the machine vision quality inspection system. For example, data such as the tolerance of the installation joint position, the relative horizontal and vertical height differences between the brackets, etc. The provided connection frame 71 is used to connect the collection component 7 and the compensation frame 5. The provided second electric cylinder 73 cooperates with the push frame 74 to facilitate pushing and pulling the sliding frame 75 to slide along the outer side of the empty cylinder 72. While sliding, the sliding frame 75 will push and pull the transmission frame 78 to make the transmission frame 78 exert a pushing or pulling force on the arc-shaped frame 76, so that it generates an angular offset along the empty cylinder 72, in order to adjust the acquisition angle of the image acquisition camera 77 as needed.

[0049] Among them, one side of the arc-shaped frame 76 away from the image acquisition camera 77 is rotatably connected with a transmission frame 78. One side of the transmission frame 78 close to the sliding frame 75 is rotatably connected with the sliding frame 75. By setting the transmission frame 78, it is used to connect the sliding frame 75 and the arc-shaped frame 76, and as the basis for applying thrust or pulling force during processing, the transmission of the structure is more reasonable. The rear side of the first electric cylinder 4 is fixedly connected with a collision prevention frame 9. The rear side of the collision prevention frame 9 is fixedly connected with a supplementary light 10. By setting the collision prevention frame 9, it can protect the image acquisition camera 77 and serve as the installation position of the supplementary light 10. The supplementary light 10 can supplement light and illuminate the acquisition position when the ambient light is poor or the light is blocked by the photovoltaic panel and it is difficult to perform image acquisition. The outer side of the empty cylinder 72 is fixedly connected with a rotating frame 11. The inner side of the rotating frame 11 is rotatably connected with the arc-shaped frame 76. The outer sides of the sliding frame 75 and the arc-shaped frame 76 are both rotatably connected with rotating blocks 12. The sliding frame 75 and the arc-shaped frame 76 are both rotatably connected with the transmission frame 78 through the rotating blocks 12. By setting the rotating frame 11, it is used to install the arc-shaped frame 76 so that the arc-shaped frame 76 can tilt and rotate along the empty cylinder 72. The provided rotating blocks 12 are used to connect the transmission frame 78, so that it has a certain angular rotation space during pushing and pulling to avoid the structure being stuck and unable to be used normally.

[0050] Working principle of this embodiment: When in use, start the second electric cylinder 73 inside the empty cylinder 72, and its telescopic end drives the push frame 74, so that the sliding frame 75 connected to the push frame 74 slides along the outside of the empty cylinder 72. The sliding frame 75 applies a thrust or a pulling force to the arc-shaped frame 76 through the transmission frame 78. Since the arc-shaped frame 76 is rotationally connected to the empty cylinder 72 through the rotating frame 11, and the sliding frame 75 and the arc-shaped frame 76 are connected to the transmission frame 78 through the rotating block 12, the structure can be guaranteed to rotate flexibly, so that the arc-shaped frame 76 generates an angular offset along the empty cylinder 72, thereby adjusting the acquisition angle of the image acquisition camera 77 according to requirements. Multiple image acquisition cameras 77 perform image acquisition on the photovoltaic support, reducing the image acquisition dead angle, obtaining image information from multiple positions, avoiding misjudgment of the machine vision quality inspection system, and acquiring data such as the tolerance of the installation joint position, the relative horizontal and vertical height differences between the supports, etc. When the ambient light is poor or the light is blocked by the photovoltaic panel, affecting image acquisition, turn on the fill light 10 behind the anti-collision frame 9 to perform fill light illumination on the acquisition position. At the same time, the anti-collision frame 9 can play a protective role for the image acquisition camera 77.
