Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a visual defect detection device for automobile seats. Background Technology

[0002] In the production process of car seats, inspectors are needed to check for appearance defects to ensure the quality of the car seats. Visual inspection uses machines to replace human eyes for measurement and judgment. Visual inspection involves using machine vision products to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the operation of on-site equipment based on the judgment results.

[0003] Currently, existing technology CN211965066U discloses a visual defect detection device, including a conveying mechanism, a guiding mechanism, a detection mechanism, and a defect removal mechanism. The conveying mechanism, guiding mechanism, and detection mechanism are all located above the worktable, with the detection mechanism above the guiding mechanism and the defect removal mechanism downstream of it. Two guiding mechanisms are provided, located on the left and right sides of the product, respectively. Each guiding mechanism includes a guiding plate, a connecting rod, and a guide rod. The guiding plate has several guide wheels installed along the product conveying direction. One end of the connecting rod has a limiting head, and the other end passes through a mounting plate and connects to the guiding plate. The mounting plate is fixed to the worktable. The guide rod is fixed to the guiding plate, and its other end passes through the mounting plate. A spring is fitted onto the guide rod, located between the guiding plate and the mounting plate. This invention ensures comprehensive and accurate image detection, and after detection, defective products are placed in a defective product storage slot, exhibiting a high degree of automation.

[0004] However, when the aforementioned visual defect detection equipment detects defects in the appearance of car seats, workers need to flip the car seats so that the camera can take pictures of each surface of the car seat in turn, which results in poor detection efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a visual defect detection device for automobile seats, which aims to solve the problem that existing visual defect detection devices require taking pictures of each surface of the automobile seat sequentially when inspecting its appearance, resulting in poor detection efficiency.

[0006] To achieve the above objectives, this utility model provides a visual defect detection device for automotive seats, including a conveyor belt, a detection component, and an ejector rod. The detection component is disposed on top of the conveyor belt, and the ejector rod is fixedly connected to the detection component and located on one side of the detection component. The detection component includes a mounting frame, a sensor head, a detection rod, a detection ring, and a lifting rod. The mounting frame is fixedly connected to the conveyor belt and located on top of the conveyor belt. The sensor head is fixedly connected to the mounting frame and located on the side of the mounting frame closer to the conveyor belt. The detection rod is fixedly connected to the mounting frame and located on top of the mounting frame. The lifting rod is disposed inside the mounting frame, and the detection ring is fixedly connected to the lifting rod and located on one side of the lifting rod.

[0007] The detection rod includes a support rod, a fill light, and a first camera. The support rod is fixedly connected to the mounting frame and is located on the top of the mounting frame. The first camera is fixedly connected to the support rod and is located on one side of the support rod. The fill light is fixedly connected to the support rod and is located on the side of the support rod closer to the first camera.

[0008] The lifting rod includes a motor, a lead screw, and a slider. The motor is fixedly connected to the mounting frame and located on the inner wall of the mounting frame. The lead screw is fixedly connected to the output end of the motor and located on one side of the motor. The slider is threadedly connected to the lead screw and slidably connected to the mounting frame, and located on the outside of the lead screw.

[0009] The detection ring includes a connecting rod, a mounting ring, and a second camera. The connecting rod is fixedly connected to the slider and is located on one side of the slider.

[0011] This utility model discloses a visual defect detection device for automotive seats. The conveyor belt transports the automotive seats to be inspected. The detection component performs visual defect detection on the appearance of the automotive seats. The ejector rod ejects the automotive seats with detected defects, rejecting defective products. The sensing head is an ultrasonic sensor, a commonly used technology on the market. During visual defect detection, the controller controls the conveyor belt to move the automotive seat to be inspected to one side of the mounting bracket. When the sensing head detects the automotive seat, the conveyor belt stops moving, and the automotive seat is positioned directly below the detection rod. The lifting rod then moves, lowering the detection ring and placing it on the outside of the automotive seat. At this time, the detection rod and the detection ring move simultaneously, inspecting the top and outside of the automotive seat. The system takes images and transmits them to a computer for appearance defect analysis, thereby detecting appearance defects in the car seats. Based on the detection results, it controls the ejector rod to eject the car seats with appearance defects from the conveyor belt, rejecting defective products. Finally, the lifting rod resets, causing the detection ring to reset, completing the inspection of the car seats. This detection component, through the setting of the detection rod and the detection ring, can simultaneously photograph and inspect all appearance surfaces of the car seats, eliminating the need to inspect each appearance surface sequentially. Compared with traditional defect detection equipment, this greatly improves the inspection efficiency of car seats and solves the problem that existing visual defect detection equipment requires sequential photographing and inspection of each surface of the car seat, resulting in poor detection efficiency.

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 3 This utility model provides a visual defect detection device for automobile seats, including a conveyor belt 1, a detection component 2, and an ejector rod 3. The detection component 2 is disposed on the top of the conveyor belt 1, and the ejector rod 3 is fixedly connected to the detection component 2 and located on one side of the detection component 2. The detection component 2 includes a mounting frame 4, a sensor head 5, a detection rod 6, a detection ring 7, and a lifting rod 8. The mounting frame 4 is fixedly connected to the conveyor belt 1 and located on the top of the conveyor belt 1. The sensor head 5 is fixedly connected to the mounting frame 4 and located on the side of the mounting frame 4 close to the conveyor belt 1. The detection rod 6 is fixedly connected to the mounting frame 4 and located on the top of the mounting frame 4. The lifting rod 8 is disposed inside the mounting frame 4, and the detection ring 7 is fixedly connected to the lifting rod 8 and located on one side of the lifting rod 8.

[0019] In this embodiment, the conveyor belt 1 is used to transport the car seat to be inspected, the inspection component 2 is used to visually inspect the appearance of the car seat for defects, the ejector rod 3 is used to eject the car seat with detected defects and reject the defective product, and the sensor head 5 is an ultrasonic sensor, which is a commonly used technology on the market. During visual defect inspection, the controller controls the operation of the conveyor belt 1 to move the car seat to be inspected to one side of the mounting bracket 4. When the sensor head 5 detects the car seat, the conveyor belt 1 stops moving, and the car seat is located directly below the inspection rod 6. The lifting rod 8 moves, lowering the inspection ring 7 and placing the inspection ring 7 on the outside of the car seat. At this time, the inspection rod 6 and the inspection ring 7 move, simultaneously taking pictures of the top and outside of the car seat. The captured images are transmitted to a computer for appearance defect analysis, thereby detecting appearance defects in the car seats. Based on the detection results, the ejector rod 3 is controlled to eject the car seats with appearance defects from the conveyor belt 1, rejecting defective products. Finally, the lifting rod 8 resets, causing the detection ring 7 to reset, completing the inspection of the car seats. The detection component 2, through the setting of the detection rod 6 and the detection ring 7, can simultaneously capture and inspect all appearance surfaces of the car seats, eliminating the need to inspect each appearance surface sequentially. Compared with traditional defect detection equipment, this greatly improves the inspection efficiency of car seats and solves the problem that existing visual defect detection equipment requires sequentially capturing and inspecting each surface of the car seat, resulting in poor detection efficiency.

[0020] Furthermore, the detection rod 6 includes a support rod 9, a fill light 10, and a first camera 11.

The slider 14 is threadedly connected to the lead screw 13 and slidably connected to the mounting frame 4, and is located on the outside of the lead screw 13.

[0023] In this embodiment, the output end of the motor 12 drives the lead screw 13 to rotate. When the lead screw 13 rotates, it drives the slider 14 to slide within the mounting bracket 4 under the action of the thread, thereby driving the detection ring 7 to move. The motor 12 changes the rotation direction of its output end by changing the direction of the current, thereby raising and lowering the detection ring 7.

[0024] Furthermore, the detection ring 7 includes a connecting rod 15, a mounting ring 17, and a second camera 18. The connecting rod 15 is fixedly connected to the slider 14 and is located on one side of the slider 14.
