Description

Technical Field

[0001] This utility model relates to the field of automotive inspection technology, and more specifically, to a visual error prevention device. Background Technology

[0002] Error-proof visual inspection is an intelligent system that uses machine vision technology to replace manual inspection, enabling automatic identification and interception of errors during the production process. Its core principles and characteristics are as follows: Technical Principles: Image Acquisition and Processing: Target images are captured by an industrial camera, converted into digital signals, and then processed using algorithms for noise reduction, enhancement, and feature extraction. Intelligent Comparison: The processed image is matched against a preset standard template or database to verify the consistency of key parameters such as product model and assembly integrity. Real-time Feedback: Inspection results directly link to the production line control system, automatically rejecting defective products or triggering alarms. It has been widely used in the automotive inspection field.

[0003] Patent authorization announcement number CN220991868U discloses a visual inspection device for preventing errors in automotive parts, including a conveyor plate. Two symmetrically arranged threaded conveyor rods are rotatably mounted on the upper surface of the conveyor plate. A motor housing is fixedly mounted on the lower surface of the conveyor plate. The two ends of the motor housing are rotatably connected to the two threaded conveyor rods on both sides through output shafts and transmission belts. A through cavity is opened in the middle of the upper surface of the conveyor plate. An electric push rod is fixedly mounted on the lower surface of the conveyor plate. A sealing plate that interlocks with the through cavity is fixedly mounted on the upper surface of the electric push rod. A mounting base is fixedly mounted on the upper surface of the conveyor plate. A processor and a camera are fixedly mounted on the upper and lower ends of the mounting base, respectively. The camera and the through cavity are matched in position. A base plate is provided on the lower surface of the conveyor plate. The motor housing and the electric push rod are fixedly mounted on the upper end of the base plate. It can inspect and recycle spherical automotive parts such as bearing steel balls.

[0004] However, in patent publication number CN220991868U, the retraction of the electric push rod can drive the sealing plate downward, thereby allowing substandard spherical parts to be pulled out and retrieved through the cavity. Spherical parts with an outer diameter smaller than the design size can be pulled out through the cavity, but spherical parts with an outer diameter larger than the design size will get stuck in the cavity and cannot be pulled out, thus affecting the applicability of the device. Therefore, we propose a visual error prevention device to solve the above-mentioned problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] Please see Figure 1-5 A visual error prevention device includes a support 1 and a through hole 2 opened in the middle of the support 1. A guide groove 3 is opened through the edge of the support 1, and multiple guide grooves 3 are arranged in the radial position of the through hole 2.

[0035] The inner side of the guide groove 3 is slidably connected to a slide block 4 with an I-shaped cross section, and the top of the slide block 4 is fixedly connected to a retainer 5 with an arc-shaped end, and the top of the retainer 5 is fixedly connected to a first connecting shaft head 6.

[0036] A top plate 8 is installed above the support 1. A turntable 9 is rotatably connected to the middle of the lower surface of the top plate 8. A shaft 11 is fixedly connected to the edge of the lower surface of the turntable 9 corresponding to the guide groove 3. A connecting rod 12 is hinged between the bottom end of the corresponding shaft 11 and the first connecting shaft head 6.

[0037] A second connecting shaft head 13 is fixedly connected to the lower edge of the top plate 8. An electric cylinder 14 is hinged to the second connecting shaft head 13. A third connecting shaft head 15 is fixedly connected to the turntable 9 on one side of the top end of the shaft 11. The third connecting shaft head 15 is hinged to the telescopic end of the electric cylinder 14.

[0038] A detection camera 16 is installed in the middle of the lower surface of the turntable 9, and a processor 17 is installed on the upper surface of the top plate 8.

[0039] It should be noted that, in use, this visual error prevention device controls the extension and retraction of the electric cylinder 14 according to the outer diameter of the spherical workpiece. Simultaneously, the tail of the electric cylinder 14 swings in conjunction with the second connecting shaft head 13, while the third connecting shaft head 15 is hinged to the movable end of the electric cylinder 14. This causes the turntable 9 to rotate relative to the top plate 8, thereby causing the connecting rod 12, hinged between the first connecting shaft head 6 and the shaft 11, to slide in conjunction with the guide groove 3, adjusting the position of the clamping seat 5. This allows the arc-shaped end of the clamping seat 5 to support the spherical workpiece. The detection camera 16 can capture images of the spherical workpiece below the camera end and transmit the image information to the processor 17. The processor 17 compares the collected images and dimensions of the spherical workpiece with the preset shape and dimensions. When a deviation occurs, the processor 17 controls the electric cylinder 14 to further adjust the position of the clamping seat 5, allowing the spherical workpiece to fall through the through hole 2. This improves applicability to spherical workpieces with different outer diameters.

[0040] like Figure 1 , Figure 2 As shown, a guide feeder 18 corresponding to the through hole 2 is welded to the lower surface of the support 1, and the edge of the feeder 18 is integrally formed with a flange.

[0041] It should be noted that when the spherical workpiece is led out through the through hole 2, it is guided by the guide feeder 18 to facilitate the recycling of the spherical workpiece.

[0042] like Figure 1 , Figure 2 As shown, there are three guide grooves 3, and the angle between the longitudinal centerlines of two adjacent guide grooves 3 and the corresponding axis of the through hole 2 is 120°. The axis of the turntable 9 and the axis of the through hole 2 are on the same straight line.

[0043] A connecting column 10 is welded to the middle of the upper surface of the turntable 9, and the connecting column 10 is connected to the top plate 8 through a bearing;

[0044] It should be noted that the spherical workpiece supported by the card holder 5 can be centrally supported, which is beneficial for the inspection camera 16 to capture images of the spherical workpiece below the camera end.

[0045] like Figure 1 As shown, support rods 7 are symmetrically and fixedly connected between support 1 and top plate 8;

[0046] It should be noted that the support rod 7 provides stable support for the support 1 and the top plate 8.

[0047] The output terminal of the detection camera 16 is electrically connected to the input terminal of the processor 17, and the output terminal of the processor 17 is electrically connected to the output terminal of the electric cylinder 14.

[0048] The arc-shaped end of the mounting bracket 5 supports a spherical workpiece.

[0049] In use: The extension and retraction end of the electric cylinder 14 is controlled according to the outer diameter of the spherical workpiece. At the same time, the tail of the electric cylinder 14 swings in conjunction with the second connecting shaft head 13, and the third connecting shaft head 15 is hinged to the movable end of the electric cylinder 14, thereby driving the turntable 9 to rotate relative to the top plate 8. This causes the connecting rod 12, which is hinged between the first connecting shaft head 6 and the shaft 11, to slide in conjunction with the guide groove 3, adjusting the position of the clamping seat 5 so that the arc end of the clamping seat 5 can support the spherical workpiece. The detection camera 16 can capture images of the spherical workpiece below the camera end and transmit the image information to the processor 17. The processor 17 compares the images and dimensions of these collected spherical workpieces with the preset shape and dimensions. When there is a deviation between the two, the processor 17 controls the electric cylinder 14 to further adjust the position of the clamping seat 5 so that the spherical workpiece can fall through the through hole 2.

[0050] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
