Description

Technical Field

[0001] The present invention relates to the technical field of plate visual detection, and in particular to a plate visual detection device and a detection method thereof. Background Art

[0002] The visual inspection device is a device that can be moved along the surface of a workpiece by hand and perform inspection and flaw detection. Existing patents, such as patent publication number CN106247083B, disclose a wheeled inspection robot, which includes a main body and a driving device. The main body is provided with a rotating shaft, and the driving device is connected to the rotating shaft by driving. The rotating shaft is provided with a magnetic wheel, and the magnetic wheel includes a wheel shell and a magnet arranged in the wheel shell. The wheel shell is fixedly connected to the rotating shaft, and the magnet is rotatably sleeved on the rotating shaft. When the above-mentioned wheeled inspection robot is in operation, the driving device drives the rotating shaft to rotate, and the wheel shell fixed on the rotating shaft rotates accordingly, thereby realizing the movement of the main body. During the movement of the main body, the magnet rotatably connected to the rotating shaft provides magnetic force to ensure that the wheel shell can be adsorbed on the inner wall or outer wall of the workpiece to walk. The wheeled inspection robot has a simple structure and good flexibility, stability and adaptability.

[0003] During use, this type of prior art lacks an effective automated adjustment and transfer structure, which makes it easy for the manual handheld inspection device to deviate from the inspection position when it is moved along the workpiece, resulting in an inability to fully inspect the interior of the workpiece, which in turn causes subsequent damage to the workpiece. Summary of the invention

[0004] In response to the technical problems raised above, a plate visualization detection device and a detection method thereof are provided, which solve the problem that when the existing manual handheld detection device is moved along the workpiece, it is easy to cause deviation in the detection position, resulting in the inability to perform sufficient flaw detection operations on the inside of the workpiece, which is easy to cause subsequent damage to the workpiece.

[0005] The technical means adopted by the present invention are as follows:

[0006] A plate visual inspection device comprises a bracket, a holding portion and a flaw detection module with adjustable spatial position. A through hole for installing the holding portion is provided at the bottom end of the bracket. In a working state, the holding portion is in contact with the side wall of the plate to be inspected. The flaw detection module is movably arranged on the bracket. The flaw detection module can be placed at any point on the upper surface of the plate to be inspected.

[0007] Furthermore, the bracket includes four vertical sections, wherein the bottoms of two vertical sections arranged side by side in the width direction are connected by a connecting plate, and the tops of the two vertical sections in the length direction are connected by a cross beam, and a guide rail is arranged on the inner side of the cross beam so that the moving mechanism of the flaw detection module can move on the guide rail.

[0008] Furthermore, the holding portion includes a guide rod, the end of which is fixedly connected to a base plate, the main body of the base plate is a circular structure, and the diameter of the base plate is larger than the diameter of the guide rod. A spring member is also fixedly connected to one side of the base plate close to the guide rod, and the other end of the bracket is provided with a mounting plate for limiting the position of the guide rod.

[0009] Furthermore, a handle is installed on the outside of the bracket, and the mounting plate is installed on the handle.

[0010] Furthermore, an electric push rod A is arranged above the guide rail, and a moving seat is installed on the output end of the electric push rod A, and the bottom of the moving seat can slide on the guide rail.

[0011] Furthermore, a guide frame is provided on the inner side of the movable seat, the main body of the guide frame is longitudinally arranged, and a longitudinal mounting hole is opened inside the guide frame, an electric push rod B is installed inside the mounting hole, and a movable platform is installed on the output end of the electric push rod B, and the movable platform can slide along the guide frame.

[0012] Furthermore, an electric push rod C is installed on the bottom end surface of the movable platform, and a mounting frame for installing a flaw detection module is installed on the bottom output end of the electric push rod C.

[0013] Furthermore, a guide wheel is provided at the bottom end of the mounting frame, and the flaw detection module is arranged at a middle position of the bottom end of the mounting frame.

[0014] The present invention also discloses a detection method of a plate visual detection device, comprising the following steps:

[0015] Step 1: Sleeve the bracket onto the outside of the workpiece, and manually hold the handle connected to the outside of the mounting plate to pull the mounting plate outward, and then fit the bottom plate fixed to the guide rod to the outer side of the workpiece to complete the clamping and limiting of the device and the workpiece;

[0016] Step 2: After the assembly is completed, according to the different positions of the workpieces to be inspected, the electric push rod A installed in the guide rail is started to push the moving seat horizontally;

[0017] Step 3: Start the electric push rod B installed in the guide frame to push and adjust the longitudinal position of the movable table. When the transverse and longitudinal position adjustments of the flaw detection module are completed, start the electric push rod C installed on the bottom end surface of the movable table to push the mounting frame downward until the flaw detection module is close to the workpiece.

[0018] Step 4: By adjusting the electric push rod A and the electric push rod B, the flaw detection module can detect flaws at any position of the workpiece.

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0034] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0035] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
