Problems solved by technology

[0002] During the punching process of angle steel for power towers, due to punching vibration, relative movement between the transmission device and the angle steel, the hole position will be unqualified, which directly affects the quality of the tower. Therefore, it is necessary to detect and sort after the hole is completed. The way of random inspection has low precision and high labor intensity, and it cannot guarantee that every angle steel is qualified

Embodiment 1

[0041] Embodiment one: see Figure 1-9 , a kind of electric tower angle steel detection device in the figure, comprises angle steel transmission mechanism, vertical lifting device, image acquisition system, is characterized in that:

[0042] The angle steel transmission mechanism includes a transmission seat, a baffle, and a transmission roller; four legs are fixed below the transmission seat for support, the main body of the transmission seat is a strip structure, and the upper surface is provided with a V-shaped groove. There are two rows of cylindrical transmission rollers arranged along the length direction on both sides. The top of the transmission rollers slightly exceeds the edge of the V-shaped groove. There is a baffle at the front end of the V-shaped groove, and a photoelectric sensor is installed on the baffle.

[0043] The vertical lifting device includes a fixed frame and a lifting mechanism; the upper part of the fixed frame is a rectangular frame, the lower part...

Embodiment 2

[0057] Embodiment two: a kind of detection method that utilizes the detection device in embodiment one to electric tower angle steel, its using method is:

[0058] ①. Select the angle steel sample, place it in the V-shaped groove, and use the vertical lifting device to lower the electromagnetic chuck to an appropriate height for adsorption. After the height is determined, fix the position of the upper limit switch; lift the sample to the detection position, and adjust the The lower limit switch, positioning screws A, B, and C of the line array camera system adjust the angle of the camera and the light source so that the center of the camera is facing the center of the side of the sample close to the camera, and the angle of the light source is determined by the quality of the image captured by the camera; the adjustment is completed Finally, fix the position of the lower limit switch, and fasten the positioning screws A, B, and C of the camera and light source accessories to fi...

Abstract

The invention discloses an angle steel detection device and detection method for an electric iron tower. The angle steel detection device comprises an angle steel conveying mechanism, a vertical lifting device and an image acquisition system, wherein the angle steel conveying mechanism is connected with a production line, and used for conveying produced angle steel to the mechanism, and limiting the direction of the angle steel through a movement roll; the vertical lifting device is used for adsorbing the angle steel into air through an electromagnetic suction disc, and avoiding vibration interference of equipment and a transmission device; the image acquisition system controls a movement support through a screw rod and then drives a camera and a light source to rapidly move and shoot, theshot images are transmitted to an upper computer and image processing is carried out, and the angle steel is conveyed to a corresponding station according to a feedback result. The angle steel detection device and detection method for the electric iron tower are capable of realizing online automatic measurement and sorting for the angle steel, and high in automation degree, lower the labor intensity of manual detection and sorting, and greatly increase the detection efficiency for the angle steel and the production efficiency.

Description

technical field [0001] The invention relates to an angle steel detection line device, in particular to a power tower angle steel detection device and detection method. Background technique [0002] During the punching process of angle steel for power towers, due to punching vibration, relative movement between the transmission device and the angle steel, the aperture hole position will be unqualified, which will directly affect the quality of the tower. Therefore, it is necessary to detect and sort after the hole is completed. The way of random inspection has low precision and high labor intensity, and it cannot guarantee that every angle steel is qualified. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention proposes that the present invention has developed a kind of electric tower angle steel detection device and detection method, adopts computer and visual measurement means, realizes line array camera image acquisitio...
