Description

Technical Field

[0001] The invention relates to the field of angle steel inspection equipment, and in particular to an angle steel inspection device and an angle steel inspection method. Background Art

[0002] Angle steel is an important part of the current iron tower manufacturing. The angle steel used to manufacture the iron tower needs to be drilled to facilitate the subsequent overlap operation between the angle steels. Therefore, the current angle steel needs to be inspected for the hole position and hole specifications and quality before assembling the iron tower. Since there is no special inspection tool that can perform the above type of inspection, the current inspection is carried out by manual handheld rulers and naked eye inspection. This inspection method is not only inefficient, but also has large errors during inspection. Summary of the invention

[0003] In view of the above problems, the present invention proposes an angle steel inspection device and an angle steel inspection method. By combining the use of a calibration ruler and a detection camera, the angle steel and the calibration ruler are inspected using the detection camera, so the inspection efficiency is higher and the inspection error is smaller.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An angle steel inspection device includes a base, a guide rail, a sliding seat, a suspension arm, a calibration ruler and a detection camera, wherein the guide rail is arranged on the base, the calibration ruler is arranged on the base, the calibration ruler and the guide rail are in a parallel state, the sliding seat is slidably matched with the guide rail, the suspension arm is arranged on the sliding seat, and the detection camera is directly or indirectly arranged on the suspension arm.

[0006] The working process of this inspection device is as follows: first, with the help of other mechanisms (including but not limited to mechanical arms), the angle steel is lifted to one side of the base, so that the angle steel is in a state parallel to the guide rail, and the sliding seat moves along the guide rail. The sliding seat takes pictures of the angle steel through the detection camera during the movement along the guide rail. The angle steel image obtained by the detection camera is analyzed by the software of the host computer (the image information taken by the detection camera is transmitted to the host computer, and the software in the host computer analyzes it) to determine whether the parameters of the hole of the angle steel (including but not limited to the hole diameter, end distance and standard distance) and other printed marks are qualified. At the same time, since a calibration ruler is also set on the base, the existence of the calibration ruler can record the position of the sliding seat (and the suspension arm) on the base, so the camera can calculate the position of each hole on the ruler by recording the position of the sliding seat on the base when taking pictures, and finally calculate whether the spacing between two adjacent holes is qualified and whether the length of the angle steel meets the standard.

[0007] In summary, this inspection device uses a calibration ruler and a detection camera in combination, and uses the detection camera to detect the angle steel and the calibration ruler, so the detection efficiency is higher and the detection error is small.

[0008] Optionally, a moving motor is further included, wherein the moving motor is arranged on the sliding seat, the base is provided with a rack, and the shaft of the moving motor is matched with the rack through a gear.

[0009] The specific function of the moving motor is to drive the sliding seat to move along the guide rail on the base platform. The existence of the moving motor can ensure that the sliding seat can stably move along the guide rail on the base platform.

[0010] Specifically in this angle steel inspection device, there are two guide rails on the base, the two guide rails are in a parallel state, and the rack is located between the two parallel guide rails. The rack is located between the two guide rails, so that the gear on the moving motor is also located between the two guide rails.

[0011] Optionally, it also includes a mounting cover, the detection camera is arranged on the mounting cover, and the mounting cover is provided with a fill light.

[0012] The function of the installation cover is to protect the detection camera and the fill light. In order to ensure that the detection camera and the fill light have good working efficiency during the photo taking operation, a mounting rod is provided in the installation cover, and the detection camera and the fill light are both mounted on the mounting rod. The detection camera is a cylindrical detection camera, and the fill light is a ring-shaped fill light. The light emitted by the fill light is distributed around the detection camera. The position of the detection camera and the fill light on the mounting rod can be adjusted as needed.

[0013] Optionally, the suspension arm is perpendicular to the guide rail.

[0014] Optionally, there are multiple detection cameras, and each detection camera is respectively arranged at a different position of the suspension arm.

[0015] The purpose of setting up multiple inspection cameras is to take pictures of different targets. Some inspection cameras are used to take pictures of angle steels. The cameras that take pictures of angle steels are used to obtain the image information of angle steels, while some cameras are used to take pictures of calibration rulers. Assuming that the inspection camera used to take pictures of the angle steels is A, and the inspection camera used to take pictures of the calibration rulers is B, when A takes pictures of the angle steels (at this time the sliding seat is in a stationary state relative to the base), B takes pictures of the calibration rulers, thereby recording the position of the sliding seat on the calibration ruler, thereby indirectly calculating the positions of the holes on the calibration ruler, and finally calculating the spacing of the holes by recording the positions of each hole on the calibration ruler. At the same time, the above method is used to calculate the length of the angle steel, and the rest is obtained through the angle cutting of the angle steel, the parameters of the holes, and whether the markings are qualified through the image information taken by A through the software analysis of the upper computer.

[0016] Specifically in this device, in order to ensure that each detection camera can operate stably, each detection camera is used with a mounting cover and a fill light.

[0017] Optionally, it also includes a screw module, which is arranged on the suspension arm, and the detection camera is arranged on the slider of the screw module.

[0018] Specifically in this inspection device, there are two screw modules, both of which are installed on the suspension arm, a connecting plate is installed on the slider of each screw module, each connecting plate is provided with a mounting cover, and each mounting cover is provided with a detection camera. In order to ensure that both sides of the angle steel can be completely photographed by the detection camera, the directions of the detection cameras on the two screw modules are distributed at an angle of 90 degrees.

[0019] Specifically, in the inspection device, the inspection camera for taking pictures of the calibration ruler is arranged on the suspension arm, and the inspection camera for taking pictures of the angle steel is arranged on the connecting plate.

[0020] Optionally, a drag chain groove is further included, wherein the drag chain groove is arranged on one side of the base and is parallel to the guide rail.

[0021] Specific drag chain slots can be used to place drag chains.

[0022] Optionally, the sliding seat is provided with a sliding limit block, the sliding limit block is slidingly matched with the guide rail, the guide rail is provided with a recess, the sliding limit block is provided with a protrusion, and the protrusion is matched with the recess.

[0023] An angle steel inspection method based on the above angle steel inspection device comprises the following steps.

[0024] First, the sliding seat is moved from one end of the angle steel to the other end. During the movement, the detection camera of the suspension arm takes a picture of the angle steel. The image information captured by the detection camera is transmitted to the host computer, which analyzes whether the various parameters of the cut angle, steel stamp and hole on the angle steel meet the standards. During the photo shooting of the angle steel, the detection camera is used to take a picture of the calibration ruler, and the scale positions of the two ends of the angle steel and each hole on the calibration ruler are recorded through the scale on the calibration ruler, and the length of the angle steel and the spacing between the holes are calculated based on the above scale positions.

[0025] The beneficial effects of the present invention are: by using the calibration ruler and the detection camera in combination, the angle steel and the calibration ruler are detected by using the detection camera, the detection efficiency is higher and the detection error is small.
