Description

Technical Field

[0001] The utility model relates to the technical field of metal plate detection, in particular to a metal plate surface detection device. Background Technique

[0002] Due to reasons such as the production environment and metal materials, it is inevitable that defects will occur on the metal plate during the production process. Therefore, it is necessary to detect the surfaces of both sides of the metal plate.

[0003] Chinese Utility Model Publication No.: CN218350132U includes a metal sheet and a conveyor belt. The metal sheet is placed on the outer surface of the conveyor belt. Above the metal sheet, there is a mounting seat. Inside the mounting seat, there is a camera installed. Inside the mounting seat, there is also a lighting lamp installed. The lighting lamp is arranged on the left side of the camera. The lighting lamp is inclined. The output end of the camera is connected with a signal line. One end of the signal line is connected with a display screen. On the top of the mounting seat, there is a sliding rod installed. Outside the sliding rod, there is a support plate installed. By setting the metal sheet, conveyor belt, conveying roller, movable rod, camera, signal line, lighting lamp, mounting seat, sliding rod, sliding plate, threaded rod, and handle, the distance between the lighting lamp, camera and the metal sheet can be adjusted, so that the picture taken by the camera can be clearer, which is convenient for the inspectors to observe whether there are defects on the metal surface.

[0004] The applicant found that there are some deficiencies in the use of this patent: after the camera takes a picture of the metal sheet, it is convenient for the staff to view. However, the camera can only take pictures of the front side of the metal sheet. The staff still need to manually turn the metal sheet over before the camera can take pictures of its back side. The labor intensity is large and it is not convenient enough. Moreover, it does not have the function of cleaning the metal sheet, and impurities and dust on the surface of the metal sheet will also affect the photography.

[0005] Therefore, the utility model designs a metal plate surface detection device to solve the problems existing in the prior art. Content of the Utility Model

[0006] The purpose of the utility model is to provide a metal plate surface detection device to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A metal plate surface detection device, comprising: a conveyor belt, outside the conveyor belt, there is a gantry. Below the inner wall of the top of the gantry, there is a disc. In the middle of the bottom of the disc, there is a camera installed. On both sides of the gantry, there are electric cylinders. The output end of the electric cylinder is connected with a U-shaped frame. Inside the U-shaped frame, there is a flipping motor installed. The output end of the flipping motor is connected with a clamping strip. Between the gantry and the electric cylinder, there is a lifting mechanism. On the top of one of the U-shaped frames, there is a cleaning mechanism.

[0008] Preferably, the lifting mechanism includes a vertical groove opened on the side wall of the gantry. A lead screw rotatably installed on the gantry is provided in the vertical groove. A slider is slidably installed on the outer side wall of the lead screw through a thread. One side of the slider is fixedly installed with an electric cylinder. An installation groove is opened on the side wall of the gantry. The top of the lead screw penetrates into the installation groove and is connected to the output end of a servo motor. An electric push rod is fixedly installed on the top of the gantry. The output end of the electric push rod is connected to the top of a disc. The electric cylinder drives the clamping strip to clamp the metal plate. Then the lead screw drives the slider to rise, so that the metal block rises. The electric push rod then drives the camera to rise to avoid affecting the rotation of the metal plate. Subsequently, the flipping motor drives the clamping strip to rotate 180 degrees, and the metal plate can be turned over without manual turning by workers, reducing the workload of the staff.

[0009] Preferably, the cleaning mechanism includes a cleaning motor installed on the top of the U-shaped frame. The output end of the cleaning motor is connected to one end of a rotating plate. A brush plate is provided at the other end of the rotating plate. The cleaning motor drives the rotating plate to rotate forward and backward, so that the brush plate rotates forward and backward, and the metal plate can be cleaned.

[0010] Preferably, the rotating plate and the brush plate are fixed by bolts, which facilitates the replacement of the brush plate.

[0011] Preferably, lighting lamps are provided around the bottom of the disc. The lighting lamps can improve the brightness and the photographing effect.

[0012] Preferably, a rubber anti-slip pad is provided on the side of the clamping strip away from the flipping motor. The rubber anti-slip pad can increase the friction between the clamping strip and the metal plate and improve the clamping effect.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model drives the clamping strip to extend through the electric cylinder to clamp and fix the metal plate. Then the lead screw drives the slider to rise, so that the metal plate rises. Subsequently, the flipping motor drives the metal plate to rotate 180 degrees to turn it over. After turning over, the camera can take a picture of the back of the metal plate. There is no need for workers to manually turn it over, reducing the workload and being more convenient;

[0015] 2. Through the arrangement of the cleaning mechanism of the present utility model, before taking a picture, the cleaning motor rotates forward and backward, so that the rotating plate drives the brush plate to rotate forward and backward to wipe the surface of the metal plate, reducing the adhesion of dust and impurities, avoiding the influence of impurities and dust on the photographing effect and avoiding affecting the detection.
