This kind of equipment is widely used in 3C electronics, automobile manufacturing, pharmaceutical industry and other industries, and replaces manual work to realize high-precision and high-efficiency detection.

[0003] At present, the connector visual inspection mostly adopts single camera scheme, and the front and back surfaces of the workpiece need to be turned over for shooting during detection, which is easy to cause position deviation of the workpiece, and may cause features such as texture and microstructure to be blocked or blurred, so that the features of the front and back surfaces cannot be accurately extracted. Moreover, the standard templates of the existing connector detection equipment are mostly stored locally in each device, lack of centralized management mechanism and difficult to be synchronized to multiple devices, which is easy to cause the templates inconsistent between different devices, and further cause detection result deviation. The data storage and viewing of most connector visual inspection equipment are limited to local end, and an effective remote data channel is not established, which leads to isolated detection data and results, cannot realize remote viewing, is not conducive to multi-scene management, and cannot meet the use requirement.

Detailed Implementation

[0022] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] This embodiment: as follows Figures 1-4 As shown, a visual inspection device for connectors includes a base 10, a control terminal and a cloud server. The base 10 is provided with a material tray 20, a material handling robot 30, an inspection component and a discharge component. A vibrating feed port 21 communicating with the material tray 20 is provided on one side of the base 10. When the vibration system is started, the material enters the material tray 20 at a uniform speed through the vibrating feed port 21 to avoid material accumulation.

[0024] The detection component is connected to the control terminal. The picking robot 30 is set above the material tray 20 and can move in three dimensions. The picking robot 30 is a spider-hand robotic arm with a suction cup 31 at its bottom. The detection component includes at least two CCD cameras. The first CCD camera 40 is set downward above the material tray 20, and the second CCD camera 41 is set upward on one side of the material tray 20. A mounting frame 11 is set above the base 10. The picking robot 30 and the first CCD camera 40 are mounted on the mounting frame 11. The first CCD camera 40 on the mounting frame 11 takes a picture of the front of the material in the material tray 20. After taking the picture, the picking robot 30 moves to the top of the target material. The bottom suction cup 31 slowly descends to contact the material and then adsorbs it. Then it rises and moves along a three-dimensional trajectory to the second CCD camera 41 to take a picture of the back side. By taking pictures with the upper and lower dual cameras, there is no need to flip the robot. The front and back features are accurately extracted. The front and back features at the same position can be compared simultaneously to maintain a stable detection effect and meet the usage requirements.

[0025] The control unit is equipped with a local operation panel, a display screen, a data acquisition module, and a first wireless connection module. The data acquisition module is connected to the first CCD camera 40 and the second CCD camera 41, respectively. The cloud server is equipped with a second wireless connection module, a standard template library storage module, a data comparison and analysis module, and a remote visualization interface. The first wireless connection module is connected to both the data acquisition module and the second wireless connection module. The data comparison and analysis module is connected to the second wireless connection module, the standard template library storage module, and the remote visualization interface, respectively. The local operation panel allows on-site personnel to adjust the detection parameters in real time. The display screen can show the preliminary visual detection results of the captured real-time images. The data acquisition module can quickly capture image data and reduce latency. The standard template library on the cloud server can uniformly store and update detection templates for different connector models without repeated importing on each device. The data comparison and analysis module supports batch data processing and storage of historical detection records, facilitating quality traceability. The remote visualization interface allows managers to monitor equipment operating status, defect rate, and other data remotely, enabling centralized management of multiple devices and reducing operation and maintenance costs.

[0026] The discharge assembly includes a defective product storage box and a discharge channel 50. A packaging material reel 51 and a receiving tray 52 are sequentially arranged along the discharge channel 50. The packaging material reel 51 is mounted above the discharge channel 50 via a first mounting plate and is connected to a drive motor 53 for rotating it. The receiving tray 52 is mounted above the discharge channel 50 via a second mounting plate and is connected to a receiving motor 54 for rotating it. The defective product storage box is located on one side of the discharge channel 50 for material inspection and judgment. If the material is determined to be defective, the picking robot 30 carries the material to the top of the defective product storage box, turns off the vacuum suction, and drops the material into the defective product storage box. If the material is determined to be qualified, the picking robot 30 transfers the material to the inlet of the discharge channel 50. The material moves outward along the discharge channel 50, the drive motor 53 starts, drives the packaging tape reel 51 to rotate, and conveys the tape along the discharge channel 50 to package the material. When the packaged tape passes the receiving reel 52, the receiving motor 54 simultaneously winds up the tape to complete the receiving work.

[0027] In use, the vibration system is activated, and the material enters the material tray 20 at a uniform speed through the vibrating feed inlet 21. The first CCD camera 40 on the mounting frame 11 captures the front of the material. The picking robot 30 moves above the target material, adsorbs the material, and then moves along a three-dimensional trajectory to the second CCD camera 41 to capture the back. The control terminal data acquisition module collects all image data and transmits it to the cloud server through the first wireless connection module. The cloud second wireless connection module receives the data, and the data comparison and analysis module compares it with the standard template library to determine whether the material is qualified or not. If it is a defective product, the robot moves above the defective product storage box, closes the vacuum, and allows the material to fall in. If it is a qualified product, the robot sends the material to the inlet of the discharge channel 50. After the material enters the channel, the drive motor 53 drives the packaging tape reel 51 to rotate, and the tape conveys and packages the material. The receiving motor 54 synchronously drives the receiving tray 52 to wind up the packaged tape, completing the receiving process.

[0028] It should be noted that in this embodiment, the detection component may also include a third CCD camera, a fourth CCD camera, a fifth CCD camera, and a sixth CCD camera. The third CCD camera and the fourth CCD camera are respectively positioned opposite each other at the front and rear ends of the material tray 20, and the fifth CCD camera and the sixth CCD camera are respectively positioned opposite each other on the left and right sides of the material tray 20. This enables 360° detection without blind spots and can identify defects such as side pin offset, corner cracks, and side plating peeling that cannot be covered by the upper and lower lenses. The defect detection rate is greatly improved, and defective products caused by blind spots are prevented from flowing downstream.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical solutions of the present invention shall still fall within the scope of the technical solutions of the present invention.
