Abstract
Description
Technical Field
[0001] This application relates to a visual inspection device for automotive brake components, belonging to the field of non-destructive testing technology for metallic materials. Background Technology
[0002] With the rapid development of the automotive industry, the demand for automotive parts is increasing. Brakes are a crucial component, their reliability directly impacting the overall safety performance of the vehicle and the safety of the driver. Currently, the manufacturing process for automotive brake shoes mainly includes cleaning, impregnation, curing, and assembly. Only by strictly controlling the standards of each process can high-quality brake components be obtained. Furthermore, brake components undergo rigorous quality inspection before installation, primarily checking for defects on the brake metal surface (micro-cracks, peeling, holes, corrosion pits, oxide scale, and other defects), the adhesion between the metal and brake pads (uniformity and continuity of adhesive application), and the firmness of the assembled components. Generally, manual inspection is used for this process.
[0003] However, manual inspection also has the following shortcomings: (1) Relatively low efficiency: The speed of manual inspection is often limited by the inspector's personal ability and fatigue level. (2) High cost: As the output of an enterprise increases, it is necessary to hire more inspectors and provide them with targeted training to meet the inspection needs, which will lead to a significant increase in labor costs. (3) Insufficient accuracy: Manual inspection is often affected by the inspector's personal experience, skills and subjective judgment, which may lead to inconsistencies in inspection results. (4) Poor sustainability: With the continuous advancement of technology and rapid changes in the market, the complexity and diversity of products are also constantly increasing, and manual inspection may be difficult to adapt to this rapid change. This limits the potential of enterprises to improve production efficiency, reduce costs and enhance competitiveness. Utility Model Content

[0005] The clamping and rotating mechanism, the feedback processing mechanism, and the visual recognition mechanism are connected in sequence.
[0006] The visual recognition mechanism includes a camera, which is positioned above the clamping and rotating mechanism at a corresponding location.
[0007] The end of the conveying mechanism corresponds to the position of the clamping and rotating mechanism.
[0008] Optionally, the conveying mechanism includes a conveyor belt and a conveyor motor that drives its movement;
[0009] The conveyor belt surrounds the outer ring of the conveyor motor.
[0010] Optionally, the clamping and rotating mechanism includes a rotating turntable, a rotating rod fixed on the rotating turntable, and an automatic control lever arm;

[0017] Working principle:
[0018] After the target Q235B workpiece is laser cleaned, the conveyor motor of the conveyor mechanism drives the conveyor belt to send the workpiece to the top of the clamp. The clamp uses mechanical and electromagnetic devices to fix the main workpiece. The high-resolution camera directly above accurately identifies one side of the workpiece. At the same time, the rotating rod achieves a 360° rotation, and the high-resolution camera accurately identifies the other two sides of the workpiece. It is then quickly compared with the good products in the database. If it is a good product, it is lowered to the next process via a rotating turntable. If it is a defective product, it is lowered to the defective product area via a rotating turntable. This process efficiently and accurately completes the visual inspection of the entire Q235B workpiece.
[0019] (1) The clamping and rotating mechanism can physically and magnetically clamp the Q235B workpiece, and can also rotate the workpiece 360° to ensure stability during the inspection and scanning process and all-round scanning of the workpiece.
[0020] (2) The automatic control lever contained in the clamping and rotating mechanism can perform a specified action after the visual recognition mechanism determines it. That is, if it is determined to be a good product, it will proceed to the next processing step; if it is determined to be a defective product, it will be directly sent to the corresponding rectification area.
[0021] (3) The AI visual recognition system contained in the visual recognition mechanism can respond to and judge the surface defects of the Q235B workpiece in a timely manner, and then send processing instructions to the feedback processing mechanism.
[0022] The beneficial effects that this application can produce include:
[0023] The present application provides a visual inspection device for automotive brake workpieces. The clamping and rotating mechanism can physically and magnetically clamp the workpiece, and can also rotate the workpiece 360° to ensure stability during the inspection and scanning process and omnidirectional scanning of the workpiece.
