Description

Technical Field

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

[0002] As we all know, after the production and processing of photovoltaic brackets are completed, various profiles will be assembled into brackets at the power generation site and installed with photovoltaic panels and other equipment. Although these equipment can perform quality inspections on the appearance and strength of individual profiles at the processing site, after assembly, the installation level and inclination of the same group of brackets are consistent, and the tolerance requirements at the joints are difficult to guarantee. They can only be inspected by manual visual observation. This method is not only inefficient, but also difficult to detect parts that do not meet the tolerance requirements.

[0003] When testing the quality of finished photovoltaic brackets, a testing device can be used. The existing technology has the problem that the assembled photovoltaic brackets can only be visually inspected at the power generation site. Due to the flatness of the terrain and the equipment installation space allowed in the environment, it is usually difficult for large-volume equipment to require and test the installation level and inclination between the finished brackets and the tolerance requirements at the joints on site. Based on the above-mentioned problems, we found that it is difficult for the existing technology to avoid the above problems at the same time for the on-site assembly quality inspection of photovoltaic brackets. Therefore, we proposed a photovoltaic bracket quality inspection device based on machine vision that can be easily carried or disassembled, and can be exempted from installation on the ground to avoid the inconsistency of different terrains. At the same time, it occupies a small space and can capture images of the assembly quality of photovoltaic brackets as the basis for machine vision quality inspection. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a photovoltaic bracket quality inspection device based on machine vision, which has the advantages of being easy to carry or disassemble and assemble, and can be exempted from installation on the ground to avoid the inconsistency of different terrains. At the same time, it occupies a small space and can capture images of the assembly quality of the photovoltaic bracket as the basis for machine vision quality inspection.

The mounting hook can facilitate the folding rod to be directly mounted on the crossbeam on the back of the photovoltaic bracket to avoid the structure being installed on the ground and being affected by the flatness of the ground. The folding rod can also be folded and placed or plugged and assembled as needed to facilitate carrying or extend its own length to serve as a supporting position for the structure. The provided sliding sleeve can facilitate sliding along the outer side of the folding rod, and the vertical height, horizontal position and pitch angle of the acquisition component can be adjusted in conjunction with the first electric cylinder adjustment frame to facilitate image acquisition from different positions as the basis for machine vision quality inspection. The provided acquisition component is used to directly acquire images through an image acquisition camera The image information of the photovoltaic bracket is equipped with multiple image acquisition cameras. Therefore, image acquisition can be performed from multiple positions on the basis of reducing blind spots in image acquisition, so as to avoid misjudgment by the machine vision quality inspection system, such as the tolerance of the installation joint position, the relative horizontal and vertical height differences between the brackets and other data. The connecting frame is used to connect the acquisition component and the compensation frame. The second electric cylinder cooperates with the push frame to facilitate the push-pull sliding frame to slide along the outside of the empty tube. 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 frame to cause it to produce an angular offset along the empty tube, so as to adjust the acquisition angle of the image acquisition camera as needed.

[0007] The present invention is further configured as follows: a side of the arc frame away from the image acquisition camera is rotatably connected to a transmission frame, and a side of the transmission frame close to the sliding frame is rotatably connected to the sliding frame.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0021] The present invention is further configured as follows: an anti-collision frame is fixedly connected to the rear side of the first electric cylinder, and a fill light is fixedly connected to the rear side of the anti-collision frame.

[0022] By adopting the above technical solution, the image acquisition camera can be protected by setting up an anti-collision frame, and as the installation position of the fill light, the fill light can provide fill light for the acquisition position when the ambient light is poor or the light is blocked by the photovoltaic panel and it is difficult to acquire the image.

[0023] The present invention is further configured as follows: a rotating frame is fixedly connected to the outer side of the empty cylinder, the inner side of the rotating frame is rotatably connected to the arc frame, the outer side of the sliding frame and the outer side of the arc frame are both rotatably connected to a rotating block, and the sliding frame and the arc frame are both rotatably connected to the transmission frame through the rotating block.

The folding rod can also be folded or plugged and assembled as needed to facilitate carrying or extend its own length to serve as a support position for the structure. The provided sliding sleeve can facilitate sliding along the outer side of the folding rod, and can adjust the vertical height, horizontal position and pitch angle of the acquisition component in conjunction with the first electric cylinder adjustment frame to facilitate image acquisition from different positions as the basis for machine vision quality inspection. The provided acquisition component is used to acquire images through an image acquisition camera The head directly collects the image information of the photovoltaic bracket.
