Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile part detection equipment, specifically to a spring short axle side portrait inspection equipment. BACKGROUND

[0002] In the automobile manufacturing industry, the quality of parts directly relates to the performance and safety of the whole vehicle. With the development of the automobile industry towards higher precision, automation and intelligence, the detection requirements of vehicle parts are becoming increasingly strict. Especially for some small-sized and complex-structured parts, traditional manual detection methods have many limitations and cannot meet the requirements of modern production lines for high precision and high efficiency.

[0003] Manual detection of vehicle parts usually relies on the experience and visual inspection of operators. This method not only has a slow detection speed, but also is prone to detection errors due to human factors. For example, when the workpiece size is small, the installation position is hidden, or the detection field of view is narrow, manual inspection often cannot fully cover all areas that need to be inspected, resulting in some defects being missed or overlooked. Due to factors such as fatigue and operation errors of the detection personnel, the accuracy and consistency of manual detection are difficult to guarantee, and production efficiency is easily reduced.

[0004] Therefore, automated and precise detection technology has gradually become an inevitable trend in the detection of vehicle parts. Using efficient image detection equipment can not only improve the accuracy of detection, but also shorten the detection cycle and improve production efficiency. Under this background, developing an efficient and precise automated detection device to solve the inconvenience and shortcomings of traditional manual detection has become an urgent need in the automobile manufacturing industry.

[0007] A spring short axle side image inspection equipment, characterized in that: the inspection equipment comprises a lifting inspection mechanism and a conveying mechanism, and the lifting inspection mechanism is arranged on the top of the conveying mechanism;

[0008] The lifting inspection mechanism comprises a guide rail cylinder, a base, a centering device, a fixed seat, an image inspection machine, a pen-shaped cylinder and a light supplementing lamp, one side of the base is installed on the sliding block of the guide rail cylinder, the other side of the base is provided with the centering device and the pen-shaped cylinder, the fixed seat is installed on the top of the centering device, the image inspection machine is movably installed on the fixed seat, and the light supplementing lamp is installed on the working end of the pen-shaped cylinder.

[0009] The conveying mechanism comprises a conveying rod, a conveying seat and a fixed tool, and the conveying seat is movably installed on the conveying rod.

[0010] Preferably, the central axis of the centering device positioning needle coincides with the central axis of the test part fixed on the fixed tool.

[0011] Through the above technical scheme, the accurate alignment of the test part during the detection process can be realized, the coaxial structure design ensures that the part is always in the ideal detection position in the visual acquisition area, avoids the problems of image distortion, recognition error and the like caused by deviation, inclination or different postures, significantly improves the stability and accuracy of image acquisition, the coincidence of the central axes simplifies the debugging process of the equipment, reduces the influence of clamping errors, and the operator can realize efficient detection without frequent position adjustment in the actual use process, reduces the complexity of manual intervention, meanwhile, the design enhances the recognition ability of the image processing system to key features such as edges and contours, and improves the repeatability and consistency of multi-batch test results.

[0012] Preferably, the cylinder body axes of the guide rail cylinder and the pen-shaped cylinder are coplanar, and the plane is axially perpendicular to the conveying rod.

[0013] Through the above technical scheme, the compactness and standardization of the equipment structure in the spatial layout can be realized, the coordinated consistency of the execution components in the running process is ensured, the cylinder body axes of the guide rail cylinder and the pen-shaped cylinder are coplanar, which is beneficial to simplify the overall structure design, improve the equipment assembly precision, avoid the problems of component interference or action inconsistency caused by installation deviation, and besides, the plane is axially perpendicular to the conveying rod, so that the lifting mechanism and the conveying mechanism are orthogonally arranged in space, the system can realize the separation and mutual non-interference of actions during operation, and the mechanical stability and action precision of the whole system are improved. Especially in the image acquisition process, the vertical structure is helpful to keep the repeated positioning precision of the inspection device in the vertical direction, and prevents the image from deviating caused by inclination or shaking.

[0014] Preferably, the image inspection machines are arranged on both sides of the centering device, and the optical axes of the image inspection machines are symmetrically distributed relative to the central axis of the centering device.

[0017] Through the above technical scheme, the problem of image acquisition quality caused by insufficient or uneven illumination can be effectively solved. Since the detection object often has small size or complex geometric shape, a single light source may not be able to illuminate all important areas of the workpiece, resulting in low image contrast and blurred details. Therefore, the symmetric arrangement of the light supplement lamps can uniformly provide illumination on both sides of the workpiece, ensuring that there are no shadow or overexposure areas during image acquisition.

[0018] Preferably, the conveying seat has an L-shaped structure.

[0019] Through the above technical scheme, the short side of the L-shaped structure is installed on the conveying rod, and the long side is used to fix and support the workpiece to be detected, so that the workpiece can always maintain the correct posture during conveying, avoiding the shaking or position deviation of the workpiece caused by unstable support. This structure design not only increases the support area of the conveying seat and enhances its stability, but also improves the overall durability of the equipment. In actual use, the L-shaped structure can effectively reduce the influence of vibration or external interference generated during conveying on the detection result, ensuring the accuracy during testing. By reducing errors and unstable factors during conveying, the L-shaped conveying seat enables the workpiece to complete detection in a relatively stable state, thereby improving the accuracy and efficiency of detection.
