Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component detection, and particularly relates to a detection bench for a relay resistor used in a new energy vehicle. Background Art

[0002] In the wave of the booming development of the new energy vehicle industry, as electric vehicles are increasingly becoming the market mainstream, the quality control of their components has been raised to an unprecedented level. As key hubs of the vehicle's electrical system, the performance stability and excellence of core components such as relay resistors are directly related to the overall safety and reliability of the vehicle. Therefore, it is particularly urgent to conduct efficient and accurate quality inspections on them.

[0003] However, most traditional detection devices rely on cumbersome manual operations, making it difficult to achieve the continuity and efficiency of the detection process. This not only limits the detection speed but also may lead to production capacity bottlenecks. More critically, manual detection is often accompanied by biases in subjective judgment, making it difficult to ensure the objectivity and accuracy of the detection results, thus posing potential risks to product quality.

[0004] In addition, traditional devices often cannot comprehensively cover the product surface during visual inspection, forming visual blind spots and resulting in the omission of some subtle defects or flaws. This incompleteness of detection undoubtedly reduces the overall quality control level of the product. At the same time, these traditional devices generally lack the support of advanced automated control systems and cannot achieve intelligent and automated management of the detection process. This not only increases the cost and risk of manual intervention but also limits the flexibility and scalability of the detection process, making it difficult to meet the rapid development needs of the new energy vehicle industry.

[0005] Therefore, it is very necessary to invent a detection bench for a relay resistor used in a new energy vehicle. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides a detection bench for a relay resistor used in a new energy vehicle, which includes a detection bench main body, a highly transparent visual detection conveyor, a visual detection frame and its camera, a computer control component, and a switch control platform. The highly transparent visual detection conveyor fixedly installed on the detection bench main body and the visual detection frame and its camera are arranged on opposite sides of each other. The computer control component is fixedly installed at one of the angles of the detection bench main body, and the computer control component is located on one side of the switch control platform fixedly installed on the detection bench main body;

[0007] A computer main unit connected to the computer control component is placed inside the detection bench main body;

[0008] The high-transparency visual inspection conveyor includes a base, columns, side plates, positioning sensors, conveyor rollers, support rollers, a conveyor belt, a support frame, a visual inspection camera, and a servo motor.

A number of support rollers are rotatably installed on two of the side plates. The support frame is fixedly installed below the side plate, and the visual inspection camera is fixedly installed on the support frame.

[0009] Preferably, there are four columns in total, two in a group. A single conveyor roller is rotatably installed at the lower end of each group of columns. The conveyor rollers rotatably installed on the columns are located on the lower side of the conveyor rollers rotatably installed on the side plates. The four conveyor rollers are arranged in an equilateral trapezoid.

[0010] Preferably, there are no support rollers installed in the middle area inside the side plate. The area without the support rollers is the visual inspection area. The camera of the visual inspection frame and its camera and the visual inspection camera are located above and below this visual inspection area, and the three are on the same vertical line.

[0021] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0022] The new energy vehicle relay resistor detection bench provided by the utility model includes a detection bench main body 1, a highly transparent visual detection conveyor 2, a visual detection frame and its camera 3, a computer control component 4 and a switch control platform 5. The highly transparent visual detection conveyor 2 and the visual detection frame and its camera 3 fixedly installed on the detection bench main body 1 are arranged on opposite sides of each other. The computer control component 4 is fixedly installed at one of the included angles of the detection bench main body 1, and the computer control component 4 is located on one side of the switch control platform 5 fixedly installed on the detection bench main body 1;

[0023] A computer main unit connected to the computer control component 4 is placed inside the detection bench main body 1.

[0024] The highly transparent visual detection conveyor 2 includes a base 21, columns 22, side plates 23, a positioning sensor 24, conveying rollers 25, support rollers 26, a conveyor belt 27, a support frame 28, a visual detection camera 29 and a servo motor 20. The base 21 is fixedly installed on the detection bench main body 1. The four corners of the base 21 are respectively fixed to the columns 22. The upper ends of the columns 22 are fixed to the side plates 23. There are two side plates 23. The positioning sensor 24 is fixedly installed outside one of the side plates 23; A total of four conveying rollers 25 are rotatably installed on the columns 22 and the side plates 23. The conveyor belt 27 is assembled on the four conveying rollers 25. Any end of one of the conveying rollers 25 rotatably passes through the side plate 23 and is fixed to the output end of the servo motor 20 fixedly installed outside the side plate 23; A number of support rollers 26 are rotatably installed on two of the side plates 23; The support frame 28 is fixedly installed below the side plate 23, and the visual detection camera 29 is fixedly installed on the support frame 28.

[0025] Further, the number of columns 22 is set to four. Every two columns 22 form a group, and a conveying roller 25 is rotatably installed at the lower end of each group. The positions of the conveying rollers 25 installed on the columns 22 are carefully arranged. They are located on the lower side of the conveying rollers 25 rotatably installed on the side plates 23, jointly forming an equilateral trapezoid distribution conveying system. Such a layout not only ensures the stability of the conveying process, but also optimizes the space utilization, making the entire detection process smoother and more efficient.

[0026] Furthermore, in the center of the inner side of the two side panels 23, an area is specially reserved without the support roller 26 installed, and the area is set as the visual inspection area. It is intended to eliminate any obstacles that may block the visual inspection and ensure that the visual inspection is carried out without obstacles. The visual inspection frame and its equipped camera 3 and visual inspection camera 29 are precisely installed above and below the visual inspection area, and the three are strictly kept on the same vertical line to ensure the accuracy and comprehensiveness of the visual inspection. In addition, the positioning sensor 24 is cleverly set on one side of the visual inspection area, which provides strong support for the precise positioning of the product.

[0027] Furthermore, the conveyor belt 27 is made of a highly light-transmitting transparent resin material, which not only has excellent light transmittance, but also ensures that every detail of the product surface can be clearly captured. The support roller 26 is cleverly located below the conveyor belt 27, with a slight gap between the two. This design ensures that when there is no product, the conveyor belt 27 and the support roller 25 will not contact each other, reducing unnecessary wear; and when the product is placed on the conveyor belt 27, the conveyor belt 27 will slightly contact the support roller 25 due to carrying the product, thereby ensuring the stability of the conveying and the accurate positioning of the product. This precise matching mechanism provides a solid foundation for high-quality visual inspection.

[0028] Here’s how it works:

[0029] Automatic conveying: One of the conveying rollers 25 driven by the servo motor 20 drives the conveyor belt 27 to move in a circular motion, automatically conveying the relay resistor to be inspected from the starting position to the visual inspection area, and automatically removing it after the inspection is completed, realizing a continuous and efficient inspection process.

[0030] Highly transparent visual inspection: The conveyor belt 27 made of highly transparent resin, combined with the visual inspection cameras 29 arranged above and below, can fully and clearly capture every detail of the product surface, including tiny scratches, flaws, etc. At the same time, by adjusting the brightness and angle of the LED light source of the visual inspection camera 29, shadows and reflections are eliminated, further improving the image quality.

[0031] Intelligent identification and positioning: The visual inspection system transmits the captured images to the computer host, and automatically analyzes and identifies whether the product has defects through advanced image processing technology and machine learning algorithms. At the same time, it uses positioning sensors 24 to accurately determine the position of the product to ensure the accuracy and reliability of the inspection.

[0032] Automation Control and Management: The computer control component 4 and the switch control platform 5 integrate an advanced automation control system, which can monitor and adjust the detection parameters in real time to ensure the stable operation of the detection process. At the same time, the system supports remote monitoring and fault diagnosis functions, improving the maintainability and usability of the equipment. In addition, all data generated during the detection process will be automatically stored in the computer host for subsequent data management and analysis.

[0033] The working process is as follows:

[0034] Preparation stage: The operator places the relay resistor to be detected at the starting position on the highly transparent vision detection conveyor 2 and starts the detection table.

[0035] Automatic conveying: The servo motor 20 starts, drives the conveying roller 25 to rotate, and then drives the conveyor belt 27 to convey the relay resistor from the starting position to the vision detection area.

[0036] Vision detection: When the relay resistor enters the vision detection area, the vision detection cameras 29 arranged up and down work simultaneously to capture the image of the product surface. At the same time, the positioning sensor 24 accurately determines the position of the product.

[0037] Intelligent identification: The vision detection system transmits the captured image to the computer host, and automatically analyzes and identifies whether there are defects in the product through image processing technology and machine learning algorithms. If there are defects, the types of defects will be classified and recorded.

[0038] Result output: After the detection is completed, the computer host outputs the detection result to the display screen or prints a report for the operator to view. At the same time, the detection table automatically removes the detected relay resistor to the designated position.

[0039] Data management and analysis: All data generated during the detection process will be automatically stored in the computer host. The operator can query historical detection records, generate detection reports or perform trend analysis and other operations as needed, providing strong support for product quality control and continuous improvement.

[0040] Using the technical solution described in the present utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
