Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically to a visual inspection device for connector terminal production and processing. Background Technology
[0002] Connector terminals, as crucial components connecting electronic components, circuit boards, cables, and other electrical equipment, are vital for the stable and reliable operation of the entire system. Therefore, strict quality control of connector terminals during manufacturing is paramount. Traditional connector terminal inspection methods typically rely on manual visual and dimensional checks. However, this method has several limitations. With the rapid development of machine vision technology, more and more industrial manufacturing sectors are adopting machine vision products for quality inspection. Machine vision technology is a technology that simulates the human visual system. It acquires images through cameras and analyzes and identifies these images using image processing algorithms. In the connector terminal inspection process, machine vision systems can efficiently acquire images of the terminals and extract and analyze features using image processing algorithms to detect appearance defects and dimensional problems.
[0003] The automotive connector image testing device disclosed in announcement number CN206002054U includes an automotive connector terminal image detection unit for detecting the quality of automotive connector terminals on a conveyor line, and an automotive connector snap-in image detection unit for detecting the quality of automotive connector snaps on the conveyor line. The automotive connector snap-in detection unit adopts a CCD image detection system.
[0004] While the aforementioned automotive connector imaging testing device can simultaneously inspect the quality of automotive connector terminals and latches, its design may not fully consider the need for comprehensive visual inspection of automotive connector terminals. Specifically, because the device cannot rotate the automotive connector terminals, it may only be able to observe a fixed angle or side of the terminal during inspection, making it difficult to conduct a comprehensive inspection of its overall appearance or specific details. This limitation may reduce the accuracy and reliability of the inspection, as some potential quality problems or defects may be missed due to the limited observation angle.
[0005] Therefore, it is necessary to invent an appearance inspection device for connector terminal manufacturing to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an appearance inspection device for connector terminal manufacturing and processing, so as to solve the problems in the above-mentioned technology.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for connector terminal production and processing, comprising a workbench, a conveyor mounted on the top of the workbench, an inspection box mounted at the middle of the top of the workbench, the inspection box being mounted directly above the conveyor, multiple evenly distributed mounting mechanisms mounted on the surface of the conveyor, each mounting mechanism including a base, the base being fixedly connected to the surface of the conveyor, a fixed plate being fixedly connected to each of the two ends of the top of the base, a first electric push rod mounted on one side of one of the fixed plates, the working end of the first electric push rod passing through the fixed plate and rotatably connected to a first clamping plate, a drive motor mounted on one side of the other fixed plate, one end of the output shaft of the drive motor passing through the fixed plate and fixedly connected to a second clamping plate, the first clamping plate and the second clamping plate being matched, a first anti-slip pad mounted on the clamping surfaces of the first clamping plate and the second clamping plate, a control panel mounted on the front of the inspection box, and the conveyor, the first electric push rod and the drive motor being electrically connected to the control panel.
[0008] By integrating key components such as worktable, conveyor, inspection box and mounting mechanism, automated appearance inspection of connector terminals is achieved; the design of the mounting mechanism enables the connector terminals to be stably clamped, and also facilitates the rotation of the connector terminals, which is convenient for subsequent inspection operations.
[0009] Preferably, a support plate is provided directly above the base, and the support plate is located between the first clamping plate and the second clamping plate.

[0011] Preferably, a second anti-slip pad is installed on the top of the support plate, and both the first and second anti-slip pads are made of rubber material.
[0012] The rubber anti-slip pads No. 1 and No. 2 increase the friction between the pads and the connector terminals, preventing them from slipping or moving during testing.
[0013] Preferably, a second electric push rod is installed at the middle position of the top of the base, the working end of the second electric push rod is fixedly connected to the bottom of the lifting plate, and the second electric push rod is electrically connected to the control panel.
[0014] The lifting plate is raised and lowered by the second electric push rod. When the lifting plate is raised, it can provide support for the connector terminals during transportation. When the lifting plate is lowered, it can avoid hindering the rotation of the connector terminals, thus improving the flexibility of the mounting mechanism.
[0015] Preferably, a telescopic rod is installed at each of the four corners of the bottom of the support plate, and the bottom ends of the four telescopic rods are fixedly connected to the base.
[0016] A telescopic rod is installed at the bottom of the lifting platform to provide additional support and stability, preventing it from tilting or swaying during lifting.
[0017] Preferably, a CCD camera is installed inside the detection box, and a No. 3 electric push rod is installed on the top of the detection box. The working end of the No. 3 electric push rod extends into the detection box and is fixedly connected to the CCD camera. Both the CCD camera and the No. 3 electric push rod are electrically connected to the control panel.
[0018] A CCD camera is installed inside the testing box, and its height is controlled by electric push rod No. 3, allowing the CCD camera to be flexibly adjusted in height.
[0019] Preferably, a light is installed on the top surface of the testing box, and the light is electrically connected to the control panel.
[0020] An illumination lamp is installed on the top surface of the inspection box to provide sufficient light for the CCD camera, enabling the camera to clearly capture the appearance details of the connector terminals, thereby improving the accuracy and reliability of the inspection.
[0021] Preferably, the testing box has an open design at both ends, and a light-blocking curtain is installed at each of the openings at both ends of the testing box.
[0022] The testing box features an open design at both ends and is equipped with a light-shielding curtain, which facilitates the entry and exit of connector terminals and effectively prevents external light from interfering with the testing process, ensuring the accuracy and stability of the testing.
[0023] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0024] The connector terminals are mounted and fixed by a mounting mechanism. The second clamping plate is rotated by a drive motor, which can achieve 360-degree rotation of the connector terminals. This allows the CCD camera to capture images of the connector terminals from multiple angles, ensuring that all parts of the connector terminals can be detected. This overcomes the problem of limited observation angle in traditional detection methods and improves the accuracy and reliability of the detection. Attached Figure Description

Each mounting mechanism 4 includes a base 5, which is fixedly connected to the surface of the conveyor 2. A fixing plate 6 is fixedly connected to each end of the top of the base 5. An electric push rod 7 is mounted on one side of one of the fixing plates 6. The working end of the electric push rod 7 passes through the fixing plate 6 and is rotatably connected to a clamping plate 8. A drive motor 9 is mounted on one side of the other fixing plate 6. One end of the output shaft of the drive motor 9 passes through the fixing plate 6 and is fixedly connected to a clamping plate 10. The clamping plates 8 and 10 are matched. Anti-slip pads 11 are installed on the clamping surfaces of both clamping plates 8 and 10. A control panel 12 is mounted on the front of the inspection box 3. The conveyor 2, the electric push rod 7, and the drive motor 9 are all electrically connected to the control panel 12.
[0034] In one aspect of this embodiment, a support plate 13 is disposed directly above the base 5, located between the first clamping plate 8 and the second clamping plate 10. A second anti-slip pad 14 is installed on the top of the support plate 13. Both the first anti-slip pad 11 and the second anti-slip pad 14 are made of rubber. A second electric push rod 15 is installed at the middle of the top of the base 5. The working end of the second electric push rod 15 is fixedly connected to the bottom of the support plate 13. The second electric push rod 15 is electrically connected to the control panel 12. A telescopic rod 16 is installed at each of the four corners of the bottom of the support plate 13.

The lighting lamp 19 is electrically connected to the control panel 12. Both ends of the detection box 3 are open-type designs. A light-blocking curtain 20 is installed at both ends of the detection box 3.
[0035] Working principle of this utility model:
[0036] Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, the connector terminal to be tested is placed on the top of the lifting plate 13 of the mounting mechanism 4 from the input end of the conveyor 2. Then, the first electric push rod 7 is activated, and the first clamping plate 8 is pushed by the first electric push rod 7 to move towards the connector terminal until the connector terminal is clamped and fixed between the first clamping plate 8 and the second clamping plate 10. The clamping surfaces of the first clamping plate 8 and the second clamping plate 10 are each equipped with a first anti-slip pad 11 to ensure that the clamping is stable and will not damage the connector terminal.
[0037] Next, the conveyor 2 is started, and the connector terminals on the mounting mechanism 4 are fed into the detection box 3 as the conveyor 2 runs. When the mounting mechanism 4 moves to the bottom of the CCD camera 17, the height of the CCD camera 17 is adjusted by the extension and retraction of the third electric push rod 18 to ensure the best shooting field of view.
[0038] The CCD camera 17 is activated to capture images of the connector terminals. The captured image data is transmitted to the control panel 12. The image processing algorithm extracts and analyzes the features of the image, which can detect the appearance defects and size problems of the connector terminals.
[0039] During the inspection process, after the lifting plate 13 is lowered by the second electric push rod 15, the second clamping plate 10 and the clamped connector terminal can be rotated by the drive motor 9. This rotation design allows the CCD camera 17 to take pictures of the connector terminal from multiple angles, thereby achieving a comprehensive inspection of the overall appearance or specific details of the connector terminal.
[0040] During the inspection process, the lighting lamp 19 is always on, and the brightness of the lighting lamp 19 can be adjusted through the control panel 12. The lighting lamp 19 provides a sufficient and stable light source for the entire inspection process to ensure that the captured images are clear and distinct. At the same time, the light-blocking curtain 20 will block the openings at both ends of the inspection box 3 to prevent external light from interfering with the shooting effect.
