Description
Technical Field
[0001] This utility model relates to the technical field of CCD missing item detection equipment, specifically a CCD missing item detection equipment for copper busbars and sheet metal parts of automotive electronic control systems. Background Technology
[0002] The CCD defect detection equipment for copper busbars and sheet metal parts in automotive electronic control systems is a high-precision automated inspection system based on machine vision technology. It is designed specifically for quality control of copper busbars and sheet metal parts in automotive electronic control systems. Its core function is to acquire surface images of copper busbars and sheet metal parts in real time through a CCD industrial camera, and use image processing algorithms and deep learning technology to accurately identify minute defects and dimensional deviations on the product surface. In the field of automotive electronic control system manufacturing, copper busbars and sheet metal parts are core conductive and structural components. Their quality directly affects the stability of the electronic control system and the performance of the whole vehicle. As the automotive industry develops towards intelligence and lightweighting, the requirements for the processing precision of copper busbars and sheet metal parts are becoming increasingly stringent. Minor defects such as missing parts (such as missing holes, missing edges, etc.) if not detected and removed in time can cause faults such as short circuits and insufficient structural strength, which seriously threaten driving safety. Traditional inspection methods rely on manual visual inspection, which is inefficient, susceptible to subjective factors, and has a high rate of missed detections. Although some automated inspection equipment has introduced CCD vision inspection technology, it has a key defect: during the transportation process, the workpiece is placed with deviations (such as angle shifts or position tilts), which causes the workpiece posture to be unstable when the CCD camera captures the image, greatly reducing the inspection accuracy. In addition, manual intervention is often required to correct the posture, causing production line to stagnate and production efficiency to be difficult to meet the needs of large-scale manufacturing. Therefore, a CCD defect detection device for copper busbars and sheet metal parts in automotive electronic control systems is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0017] Please see Figures 1-6 This utility model provides a technical solution: A CCD defect detection device for copper busbars and sheet metal parts of an automotive electronic control system includes a support frame 1. A conveyor belt body 2 is fixedly installed on the inner side of the support frame 1. An equipment frame 3 is fixedly installed in the middle of the upper surface of the support frame 1. A linear motor 4 is fixedly installed on the top of the equipment frame 3. A mounting seat 5 is fixed to the moving end of the linear motor 4. A CCD detection camera 6 is fixed to the outer side of the mounting seat 5 by bolts. The detection end of the CCD detection camera 6 corresponds to the middle of the conveyor belt body 2. An automatic correction mechanism 8 is fixed to the front end of the support frame 1. The automatic correction mechanism 8 includes two correction mechanism supports 81. A support seat 82 is fixed inside the correction mechanism support 81. An electric cylinder 83 is fixed to the top of the support seat 82. A rubber push plate 84 is fixed to the telescopic end of the electric cylinder 83. A feeding mechanism 85 is installed between the two rubber push plates 84. A baffle 86 is fixed below the feeding mechanism 85. To further explain, the linear motor 4 can drive the mounting base 5 and the CCD inspection camera 6 to move, adapting to different position inspection needs and ensuring comprehensive inspection. The rubber push plate 84 is made of flexible material, which avoids damage to the workpiece when correcting the workpiece posture, and at the same time realizes the spacing adjustment and posture correction action. The minimum distance between the two rubber push plates 84 is the length of the feeding mechanism 85. The length of the feeding mechanism 85 can be customized according to the width of the copper busbar and sheet metal parts of the automotive electronic control system. As a further implementation of this solution, the feeding mechanism 85 includes two guide rods 851. The guide rods 851 are fixedly installed on the top of one side of the rubber push plate 84. A connecting block 852 is fixed to the front end of the guide rod 851. A limit seat 853 is fixed to the front end of the connecting block 852. A guide protrusion 854 is fixed at the center of the top of the limit seat 853. A rotating sleeve 855 is slidably fitted on the outer side of the two connecting blocks 852. Two left-right symmetrical turning grooves 856 are opened on the outer wall of the rotating sleeve 855. The inner side of the turning groove 856 has an arc-shaped structure. The turning groove 856 and the guide protrusion 854 are slidably fitted. The edge of the top of the guide protrusion 854 has a chamfered structure. To further explain, the included angle between the two ends inside the steering chute 856 is 90°. In its natural state, the guide protrusion 854 is located at the front end of the steering chute 856. At this time, the baffle 86 is in a state perpendicular to the conveyor belt body 2, which limits the workpiece. As a further implementation of this scheme, the center of the rotating sleeve 855 and the center of the guide rod 851 are located on the same axis. The rotating sleeve 855 is fixedly connected to the baffle 86. A spring mounting seat 857 is fixed in the middle of the inner wall of the rotating sleeve 855. Supporting springs 858 are fixed at both ends of the spring mounting seat 857. The two supporting springs 858 are located on both sides inside the rotating sleeve 855. One end of the supporting spring 858 is in contact with one end of the limiting seat 853. To further explain, the rotating sleeve 855 is coaxial with the guide rod 851 to ensure no eccentric wobbling during rotation. The support spring 858 is fixed by the spring mounting seat 857 to buffer the force during correction and avoid damage to the workpiece. At the same time, it meets the precise requirements of CCD detection for the workpiece posture and improves the reliability of detection. As a further implementation of this scheme, two correction mechanism supports 81 are fixedly installed on both sides of the front end of the support frame 1 by bolts. The two correction mechanism supports 81 are symmetrically distributed from left to right, and a screen 7 is fixed on one side of the equipment frame 3. To further explain, the correction mechanism support 81 is symmetrically fixed to the support frame 1 to ensure balanced force distribution. The screen 7 displays the detection image in real time, matching the real-time display function of the equipment, facilitating monitoring by the operator. As a further implementation of this solution, a sliding guide rod 87 is fixed to the rear end face of the rubber push plate 84, and the outer side of the sliding guide rod 87 is slidably connected to the inside of the correction mechanism support 81. To further explain, the sliding guide rod 87 slides in conjunction with the straightening mechanism support 81 to ensure that the rubber push plate 84 moves smoothly, and its guiding function ensures accurate straightening action and reduces workpiece offset; Workflow: The operator places the copper busbar or sheet metal part of the automotive electronic control system to be inspected at the front end of the conveyor belt body 2, starts the equipment, and the conveyor belt body 2 rotates, driving the workpiece to the inspection area in the middle of the equipment. When the workpiece moves with the conveyor belt body 2 to the feeding mechanism 85 area of the automatic correction mechanism 8, the baffle 86 is initially restricted by the cooperation between the guide protrusion 854 and the turning chute 856. In its natural state, the guide protrusion 854 is located at the front end of the turning chute 856, and the baffle 86 is perpendicular to the conveyor belt body 2, which limits the workpiece and prevents it from moving forward. The workpiece stays and waits for correction. The electric cylinders 83 inside the supports 81 of the two correction mechanisms are activated by the synchronous controller. The telescopic ends of the electric cylinders 83 extend, pushing the rubber push plates 84 forward and reducing the distance between the two rubber push plates 84. During the movement, the rubber push plates 84 drive the guide rods 851 and the connecting blocks 852 to move. The guide protrusions 854 slide along the arc-shaped trajectory inside the steering groove 856. Because the included angle between the two ends of the steering groove 856 is 90°, it drives the rotating sleeve 855 to rotate, thereby driving the baffle 86 to change its angle rotation range of 0-90°. At the same time, the rotating sleeve The inner support spring 858 of 855 provides a buffer for the movement of the connecting block 852 to avoid damage to the workpiece. The workpiece posture is corrected by adjusting the distance between the rubber push plates 84 on both sides and the angle change of the baffle 86, so that the angle deviation is less than 25° and the workpiece is separated from the rubber push plate 84. When the guide protrusion 854 moves to the inner rear end of the turning slide 856, the rotating sleeve 855 and the baffle 86 stop rotating. The baffle 86 releases the restriction on the workpiece. Under the action of the conveyor belt body 2, the workpiece automatically moves out of the feeding mechanism 85 and enters the detection area. When the workpiece enters the inspection area and reaches directly below the CCD inspection camera 6, the linear motor 4 drives the mounting base 5 and the CCD inspection camera 6 to move and adapt to different inspection positions, and the CCD inspection camera 6 acquires images of the workpiece. The acquired images are transmitted to the system and compared with the preset standard workpiece images according to the qualified specifications of copper busbars and sheet metal parts. The system uses image recognition algorithms such as edge detection and feature matching to determine whether there are any missing items or defects. The detection results are displayed on the screen 7 in real time for operators to view and pick out unqualified products. Once the workpieces have been inspected, qualified products are transported to the end of the conveyor belt 2 to enter the next process. Unqualified products are removed manually or by a subsequent sorting mechanism to complete the inspection process. All links in the process work together without the need for long-term downtime, ensuring the smooth operation of the production line.
