Description

Technical Field

[0001] The utility model relates to the field of defect detection of galvanized steel plates, in particular to a detection tool for surface defects of galvanized steel plates. Background Art

[0002] Galvanized steel plates are a commonly used type of steel plate at present. Due to many uncertain and uncontrollable factors during galvanization, there are certain defects such as coating cracks and coating gaps on the surface of current galvanized steel plates. For galvanized steel plates with certain defects, it is necessary to identify and mark them to facilitate subsequent classification management of defective and non-defective steel plates by warehouse management personnel. In order to identify defective galvanized steel plates, the patent publication document CN111982913A discloses a device that can identify surface defects of galvanized steel plates. However, this device can only identify whether there are bad points on the surface of galvanized steel plates and cannot print marks on these defective steel plates. There is still manual marking, and the operation is cumbersome. Content of the Utility Model

[0003] The utility model aims at the above problems and proposes a detection tool for surface defects of galvanized steel plates.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A detection tool for surface defects of galvanized steel plates includes a gantry, a guide rail, a sliding frame, a lifting rod, a mounting plate, a telescopic cylinder, an industrial camera, and a laser marking head. The gantry is fixedly arranged on the ground. The guide rail is arranged on the gantry. The sliding frame is slidably arranged on the guide rail. The lifting rod is slidably installed on the sliding frame and is perpendicular to the guide rail. The telescopic cylinder is installed on the sliding frame. The cylinder rod of the telescopic cylinder is cooperated with the mounting plate or the lifting rod. The mounting plate is arranged on the lifting rod. The industrial camera and the laser marking head are both arranged on the mounting plate.

[0006] In this detection tool, a conveying bag is used to convey galvanized steel plates under the gantry. During the conveying of galvanized steel plates, the mounting plate needs to be located above the galvanized steel plate. The industrial camera on the mounting plate takes pictures of the galvanized steel plate for identification. By taking pictures, it is judged whether there are defects such as cracks on the galvanized steel plate. If there are defects, the laser marking head is used to print marks on the galvanized steel plate, realizing the synchronization of defect detection and defect marking, and the operation efficiency is higher.

[0007] It should be noted that this tool can only detect one side of the galvanized steel plate at a time. If it is necessary to detect the other side of the galvanized steel plate, it is necessary to turn over the galvanized steel plate with the help of a manipulator or manually to carry out the detection.

[0008] It should be noted that in this kind of tooling, the mounting plate is installed on the lifting rod. Therefore, the position of the mounting plate relative to the sliding frame can be adjusted by the telescopic cylinder. In this way, when detecting galvanized steel sheets with different thicknesses, the height of the mounting plate relative to the galvanized steel sheet can be adjusted by the telescopic cylinder.

[0009] It should be noted that this tooling can not only be used for defect detection of galvanized steel sheets, but also for defect detection of other plate-like objects such as ceramic tiles and marble.

[0010] In this tooling, since the sliding frame is slidably installed on the guide rail and can move on the guide rail, the position of the sliding frame on the gantry can be adjusted as needed.

[0011] In summary, by combining the industrial camera and the laser marking head, this tooling can perform defect detection and defect marking simultaneously, making the operation more convenient.

[0012] Optionally, there are four lifting rods. The four lifting rods are all slidably arranged on the sliding frame, and the end of each lifting rod is fixed to the mounting plate. The other end of each lifting rod is fixed to the limit plate. The four lifting rods are in a parallel state, and the cylinder rod of the telescopic cylinder is in a parallel state with the lifting rods.

[0013] Four lifting rods are provided. One end of each lifting rod is engaged with the mounting plate, the other end of each lifting rod is fixedly engaged with the limit plate, the cylinder rod of the telescopic cylinder is engaged with the mounting plate, and the telescopic cylinder directly drives the mounting plate to move up and down. The lifting rods ensure the stability of the mounting plate during the up and down movement. At the same time, the limit plate provided at the other end of the lifting rod can prevent the lifting rod from sliding out of the sliding frame.

[0014] Optionally, the lifting rod is a square tubular lifting rod, and rollers are rotatably arranged on the sliding frame. The lifting rod is slidably engaged with the rollers.

[0015] Rollers are provided on the sliding frame. The wheel surface of the rollers contacts the rod wall of the lifting rod. The contact between the rollers and the lifting rod can reduce the friction force during the lifting of the lifting rod.

[0016] Optionally, it further includes a protective cover. The protective cover is arranged on the sliding frame, and the rollers are located inside the protective cover.

[0017] The function of the protective cover is to protect the rollers and prevent foreign objects from getting stuck between the rollers and the lifting rod.

[0018] Optionally, a wheel shaft is rotatably arranged on the sliding frame, and a traveling wheel is installed on the wheel shaft. The traveling wheel is slidably engaged with the guide rail.

[0019] Optionally, a traveling motor is provided on the sliding carriage. A sprocket is mounted on the rotating shaft of the traveling motor, and a sprocket is provided on the wheel shaft. The sprocket on the rotating shaft is engaged with the sprocket on the wheel shaft through a chain.

[0020] Specifically in this tooling, the traveling motor drives the wheel shaft to rotate through the sprocket and the chain. When the wheel shaft rotates, the sliding carriage can be moved on the guide rail.

[0021] Specifically in this tooling, in order to facilitate the maintenance of the guide rail and the sliding carriage, a ladder and a guardrail are provided on the gantry, and the staff can climb onto the gantry with the help of the ladder.

[0022] Optionally, a plurality of supplementary light lamps are provided on the mounting plate, and the supplementary light lamps are distributed around the industrial camera.

[0023] The function of the supplementary light lamp is to provide supplementary light when needed. The supplementary light lamps are distributed around the industrial camera, and the supplementary light lamps are turned on when supplementary light is needed. Specifically, the supplementary light lamp can be an LED supplementary light lamp.

[0024] The beneficial effect of the present utility model is that by combining the use of an industrial camera and a laser marking head, defect detection and defect marking can be carried out simultaneously, and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The industrial camera 7 and the laser marking head 9 are both arranged on the mounting plate 3.

[0033] In this detection tooling, a conveying bag is used to convey galvanized steel plates under the gantry 5. During the process of conveying the galvanized steel plates, the mounting plate 3 needs to be located above the galvanized steel plates. The industrial camera 7 on the mounting plate 3 takes pictures of the galvanized steel plates for identification. By taking pictures, it is judged whether there are defects such as cracks on the galvanized steel plates. If there are defects, the laser marking head 9 is used to print marks on the galvanized steel plates, realizing the synchronization of defect detection and defect marking, and the operation efficiency is higher.

[0034] It should be noted that this tooling can only detect one side of the galvanized steel plate at a time.
