Description

[0002] The workpiece refers to the object to be processed during the machining process. It can be a single part or a combination of several parts fixed together. There are various ways to process the workpiece, including turning, milling, planing, grinding, casting and forging, etc. The processing procedures of the workpiece also change with the change of the processing method. The workpiece is also called a manufactured part, a workpiece, a courseware and hardware, etc.

[0003] After existing workpieces are processed, some workpieces with obvious surface features are inspected by visual inspection to check whether there are defects on the workpiece surface. The inspection scope includes: dimensional measurement, shape and position errors, surface accuracy, and surface defects.

[0004] Although existing visual inspection devices can detect defects, their detection range is single. Only a single detection target of the workpiece can be measured in one inspection, which leads to the need for repeated measurements, affecting the inspection efficiency. At the same time, existing visual inspections require observation of multiple surfaces of the workpiece. The existing flipping structure is used to flip the workpiece, but after flipping, it cannot ensure that the workpiece is on the same baseline, resulting in shape errors during inspection, making the measurement data unable to be used as an effective data reference.

[0005] Based on this, it is necessary to propose a vision-based intelligent rapid detection method and device. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The processing methods of workpieces mainly include cutting, grinding and special processing. These methods are widely used in different fields. Cutting is a processing method that uses tools to cut, flatten and cut workpieces. The main methods of cutting are turning, milling, planing, drilling, etc. This processing method is suitable for processing various materials such as metal, wood, plastic, etc. The advantages of cutting are high processing efficiency, high precision and wide application range, but the disadvantages are also obvious, such as fast tool wear and high heat generated during processing; Grinding is a processing method that uses abrasive tools (such as grinding wheels, abrasive belts, etc.) to grind and polish the surface of the workpiece. Grinding Grinding is mainly suitable for machining workpieces with high hardness, high precision and high surface quality, such as bearings and gears. The advantages of grinding are high machining precision, good surface quality and wide application range, but the disadvantages are also obvious, such as low machining efficiency, fast wear of abrasive tools and high machining cost. Special machining refers to a method of machining workpieces by non-traditional means such as electricity, magnetism, sound, light and heat. Common special machining methods include EDM, laser machining and ultrasonic machining. Special machining is suitable for machining difficult-to-machine materials, complex shapes and workpieces with high precision requirements. The advantages of special machining are high machining precision, wide application range and the ability to achieve machining tasks that are difficult to complete with traditional machining methods. But the disadvantages are high machining costs and difficult equipment maintenance.

[0042] Existing workpiece inspection uses visual inspection to determine whether there are defects on the workpiece surface. This is mainly done by taking photos of the workpiece surface and comparing the photos with normal workpieces to determine the integrity of the workpiece surface.

[0043] However, the existing shooting method requires adjustment of the spatial position of the workpiece, which results in different positions of the workpiece in subsequent shooting, and the surface feature records of the workpiece cannot be combined, resulting in the inability to perform effective comparison later, which in turn affects the accuracy of subsequent visual inspection of the workpiece.

[0045] Step 1: Place the required cameras on the top, bottom and one side of the transparent base, and the workpiece is placed on the transparent base;

[0046] Step 2: Connect the camera to the computer via Wi-Fi or Bluetooth to control the camera's shooting;

[0047] Step 3: First, control the top and bottom cameras to take structural photos of the upper and lower surfaces of the workpiece. After the photos are taken, they are automatically stored in the computer.

[0048] Step 4: When photographing the outside of the workpiece, the camera is moved around the midpoint of the workpiece, and a photo is taken each time it moves to the outside of the workpiece until the outside of the workpiece is completely recorded;

[0049] Step 5: After the shooting is completed, the photos taken are reviewed by computer, and the surface integrity of the workpiece is checked by visual observation. The inspection scope includes: size, shape and position errors, accuracy and defects, etc.

At this time, the motor 532 works to drive the bidirectional screw rod 538 to rotate, so that the clamping block 533 moves relatively, thereby clamping the camera 6. Insert one end of the required C-shaped clamping block 537 into the inside of the slot 536 provided on the outside of the clamping block 533, and the inner side of the other end of the C-shaped clamping block 537 fits with the upper surface of the camera 6, thereby completing the installation of the camera 6. When taking pictures, the shooting distance between the camera 6 and the workpiece can be adjusted by the operation of the electric telescopic rod 520.

[0055] After completion, the camera 6 is controlled to work, and the camera 6 takes a picture of the lower surface of the workpiece.

[0056] As a preferred technical solution of the present invention, the top component 2 includes an L-shaped frame 240, a slide groove 210 is opened on one side of the upper surface of the base 1, and a screw 220 is rotatably connected inside the slide groove 210. The interior of one end of the L-shaped frame 240 is threadedly connected to the outer surface of the screw 220, and the inner side of the other end of the L-shaped frame 240 is fixedly connected to the U-shaped frame 510.

[0057] The motor 230 drives the screw 220 to rotate, and the screw 220 adjusts the position of the L-shaped frame 240 on the upper surface of the base 1, so that the photographing component 5 on the top component 2 is in the middle position of the upper surface of the workpiece. At this time, the upper surface of the workpiece can be photographed. After the photographing is completed, the motor 230 works again to drive the L-shaped frame 240 to move the knife to the initial position, so that the subsequent surrounding component 3 can perform surrounding photography.

[0058] As a preferred technical solution of the present invention, the surrounding component 3 includes an annular frame 320, the lower surface of the annular frame 320 is fixedly connected to the upper surface of the base 1, an annular groove 321 is provided on the outer side of the annular frame 320, and a toothed annular block 322 is rotatably connected inside the annular groove 321, and an L-shaped frame 2 310 is fixedly connected to the upper outer side of the toothed annular block 322, and a slide groove 2 311 is provided on the inner side of the L-shaped frame 2 310, and a screw 2 312 is rotatably connected inside the slide groove 2 311, and a slider 313 is threadedly connected to the outer surface of the screw 2 312, and the outer side of the slider 313 is fixedly connected to the U-shaped frame 510, and a motor 330 is installed on the side of the base 1, and the output shaft of the motor 330 is fixedly connected to the gear 340, and the gear 340 is meshed with the toothed annular block 322, and a motor 2 314 is installed at the end of the L-shaped frame 2 310, and the output shaft of the motor 2 314 is fixedly connected to the end of the screw 2 312.

After the camera 6 takes photos of one side, the third motor 330 is operated, and the third motor 330 drives the gear 340 to rotate. The gear 340 drives the toothed annular block 322 meshing with it to rotate in the annular groove 321 provided inside the annular frame 320, thereby driving the photographing assembly 5 to rotate in a surround manner, and taking photos of the surroundings of the workpiece;
