Description

Technical Field

[0001] This utility model relates to the field of industrial automation testing technology, and in particular to a bearing bridge camera error-proof testing line. Background Technology

[0002] With the development of intelligent manufacturing in the automotive industry, higher requirements have been placed on the assembly quality and traceability of key components. As an important part of the chassis transmission system, the bearing axle undertakes the core tasks of supporting and transmitting power during vehicle operation, and its assembly quality is directly related to the stability and safety of the entire vehicle. To ensure the accuracy of the bearing axle assembly process, major automakers have gradually introduced automated inspection lines in recent years, using image recognition and sensor feedback mechanisms to achieve error-proofing inspections at key assembly steps. Among them, the "bearing axle camera-based error-proofing inspection line" has become an indispensable and important part of the current quality control system, responsible for the rapid and accurate visual inspection of key parameters such as bolt positioning, part orientation, and component alignment during the bearing axle assembly process, in order to improve product quality and consistency.

[0003] Existing bearing bridge error-proofing inspection lines mainly employ single-station or linear inspection structures. After the bearing bridge completes partial assembly, it is conveyed to a designated inspection position by a transport line, where it is captured and identified by a set of fixed industrial cameras. These cameras are typically located on the side or top of the assembly line, using ring lights to provide uniform illumination to identify key features such as whether screws are in place and whether components are correctly positioned. Some systems also integrate position sensors and PLC logic control modules to trigger image acquisition and judgment logic, thereby achieving online real-time inspection. After inspection, based on the image processing results, defective products are rejected by a sorting device, while qualified products continue to the next process. This type of inspection system has a simple structure and high stability, and has been widely used in the standardized assembly inspection of small and medium-sized parts.

[0004] However, existing bearing bridge error-proofing inspection systems generally suffer from problems such as a single visual inspection angle and scattered identification information. Due to the use of a single camera or fixed viewing angle, the inspection area is limited by the camera's installation position, making it difficult to comprehensively cover the assembly status of multiple key parts of the bearing bridge, easily leading to blind spots or misjudgments. Furthermore, current inspection results are mostly not linked to a unique identifier for each individual product (such as a QR code), recording images and judgment data only with timestamps or batch numbers, lacking a complete "one item, one code" traceability mechanism. This makes it difficult for companies to quickly and accurately trace back to the specific defective product and its assembly process when quality anomalies or customer complaints occur, affecting the efficiency of quality problem investigation and the accuracy of responsibility identification. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a bearing bridge camera error prevention detection line, which aims to improve the problem that the existing structure lacks a multi-angle visual detection unit and the detection information is not bound to a QR code, making it difficult to achieve one-item-one-code traceability when there are quality abnormalities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing bridge camera error prevention detection line, including a bracket, a conveying mechanism fixedly connected to the upper surface of the bracket, a protective shell fixedly connected to the outer wall of the conveying mechanism, and an identification component disposed inside the protective shell;

[0007] The identification component includes camera one and camera two, both of which are housed inside a protective shell. A support frame is fixedly connected to the upper surface of the conveying mechanism, and a QR code marking machine is fixedly connected to the inner wall of the support frame. A fixing plate one is fixedly connected to the inner wall of the protective shell, and a fixing plate two is fixedly connected to the outer wall of the fixing plate one. The outer wall of the fixing plate two is fixedly connected to the inner wall of camera one. A connecting plate one is fixedly connected to the upper surface of the conveying mechanism, and the upper surface of the connecting plate one is fixedly connected to the lower surface of camera two. A counter is fixedly connected to the outer wall of the conveying mechanism. A bearing bridge body is provided on the upper surface of the conveying mechanism, and a bearing body is provided on the upper surface of the bearing bridge body.

[0008] Furthermore, a second connecting plate is fixedly connected to the upper surface of the conveying mechanism, a sliding plate is fixedly connected to the upper surface of the second connecting plate, a push block is slidably connected to the inner wall of the sliding plate, a first connecting block is fixedly connected to the outer wall of the push block, a second connecting block is rotatably connected to the outer wall of the first connecting block, a push plate is fixedly connected to the outer wall of the second connecting block, a cylinder is fixedly connected to the upper surface of the sliding plate, the output end of the cylinder is rotatably connected to the inner wall of the second connecting block, a fixing block is fixedly connected to the lower surface of the second connecting plate, a sliding bucket is rotatably connected to the outer wall of the conveying mechanism, and a collection box is attached to the outer wall of the support.

[0009] Furthermore, a control box is fixedly connected to the outer wall of the support, and the control box is located below the conveying mechanism.

[0010] Furthermore, a motor is provided on the outer wall of the conveying mechanism, and the output end of the motor is fixedly connected inside the conveying mechanism.

[0011] Furthermore, a crossbeam is fixedly connected to the upper surface of the connecting plate, and a display is fixedly connected to the upper surface of the protective shell.

[0012] Furthermore, the inner wall of the fixed block is fixedly connected to the outer wall of the conveying mechanism, and the hopper is positioned above the collection box.

[0013] Furthermore, the inner wall of the protective shell is fixedly connected to the upper surface of the conveying mechanism.

[0014] Furthermore, the first camera is positioned above the bearing body, and the second camera is positioned on one side of the outer wall of the bearing body.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting a conveying mechanism on the bracket and integrating a QR code marking machine and a dual-camera recognition component on the conveying mechanism, multi-angle, high-precision automatic detection of the bearing bridge body and its key assembly features is realized. Camera 1 and Camera 2 comprehensively identify key components such as O-rings, pressure balls, spring sleeves and airtight points from the top and side walls of the bearing body, respectively. This effectively avoids the problems of missed detection and misjudgment caused by single or missing perspectives in traditional detection. At the same time, the unique identifier of the QR code is bound and saved with the detection image, which greatly improves the convenience and accuracy of product quality traceability.

[0017] 2. In this utility model, the cylinder-driven pusher removes the unqualified bearing bridge body from the conveying path in a timely manner, preventing defective products from flowing into subsequent assembly and airtightness testing processes. This improves the error prevention efficiency of the production line and the consistency of product quality. The overall structure is reasonable and compact. The rejection mechanism and the vision inspection system form a closed-loop control, realizing automatic sorting without manual intervention. This significantly improves the automation and intelligence level of inspection and meets the production needs of modern high-speed production lines. Attached Figure Description

The motor 10 is installed on the outer wall of the conveying mechanism 2, and the output end of the motor 10 is fixedly connected to the inside of the conveying mechanism 2. The crossbeam 18 is fixedly connected to the upper surface of the connecting plate 16. The display 8 is fixedly connected to the upper surface of the protective shell 9.

The inner wall of the protective shell 9 is fixedly connected to the upper surface of the conveying mechanism 2. Camera 14 is set above the bearing body 6. Camera 27 is set on one side of the outer wall of the bearing body 6. Camera 217 detects the presence of two pressure steel balls, spring sleeve and airtight point, and reads QR code information to realize multi-feature assembly inspection and identification.

[0029] Working Principle: When the bearing bridge camera error-proofing detection line is required, this device uses a conveying mechanism 2 set on the bracket 1. The conveying mechanism 2 is equipped with a QR code marking machine 12 and two camera components, camera one 14 and camera two 17. This enables automatic identification and binding traceability of multiple detection features on the bearing bridge body 5. Camera one 14 is mounted inside the protective shell 9 via a fixing plate two 15, directly above the bearing body 6, and is used to detect the presence of two O-rings in the bearing bridge assembly and identify any missing O-rings. Camera two 17 is positioned on the bearing body... On one side of the outer wall, it is used to detect the presence of two pressure steel balls, spring sleeve, and airtight point from the side, as well as to read QR code information. The QR code marking machine 12 marks each bearing bridge with a unique QR code before identification, realizing one item one code marking. After the inspection is completed, the camera 14 and camera 2 17 save the captured images according to the QR code naming method, so that the inspection record of each product corresponds one-to-one with the QR code, providing image evidence for subsequent quality traceability and anomaly tracing, thereby effectively solving the problem that it is difficult to bind and trace the inspection information with the product in the traditional structure.

[0030] Furthermore, after the recognition component completes image acquisition and data analysis, if camera 14 or camera 217 determines that the current bearing bridge body 5 has a defect and does not meet the preset quality standard, the control box 3 will issue a rejection command, driving the cylinder 7 installed on the slide plate 21 to move. The output end of the cylinder 7 is rotatably connected to the push plate 24 through the connecting block 25. The connecting block 25 is also rotatably connected to the connecting block 1 23, and the connecting block 1 23 is connected to the push block 22, thereby driving the push block 22 to slide along the slide plate 21. During the operation of the conveying mechanism 2, the unqualified bearing bridge body 5 is pushed out from the conveying path and guided to the hopper 27 on one side of the conveying mechanism 2. The hopper 27 is set above the collection box 26, so that the rejected parts fall into the collection box 26 in a concentrated manner, avoiding them from flowing into subsequent assembly or airtightness testing processes. This rejection structure, combined with the visual recognition system, forms a closed-loop control, which can automatically complete the detection and sorting without manual intervention, effectively improving the error prevention efficiency and the intelligent level of the production line, and ensuring the consistency of product quality throughout the line.
