The alarm light 90, the touch screen, the keyboard and the PC analysis interface are all electrically connected to the controller.
[0057] Working principle of the testing equipment:
[0058] First, at the initial position, according to the size of the part to be detected 10, various parameters are set in the controller, such as the parameters required to move the second side plate 313, and the positions of the first fine-tuning mechanism 622 to the fourth fine-tuning mechanism 633 are set according to the size of the part to be detected 10 to adjust the angles of the first camera 621 and the second camera 631. The tooling plate 20 loaded with the part to be detected 10 flows into the detection station in the AOI detection equipment through the assembly line. After encountering the blocker 70, after the induction switch is actuated, the third driving component 41 in the lifting module 40 is actuated to lift the tooling plate 20 loaded with the part to be detected 10 out of the conveying module 32, and let the part to be detected 10 contact the cover plate 316. At this time, the manipulator 50 moves the first camera 621 and the second camera 631 to the top of the part to be detected 10, and completes the detection of the appearance defects of the part to be detected 10 through the first camera 621. After completing this action, the part to be detected 10 is powered on to light up the micro The LED lamp beads complete the lighting detection of the part to be detected 10 through the second camera 631. After the detection is finally completed, the manipulator 50 drives the first camera 621 and the second camera 631 back to the initial position, and the third driving component 41 in the jacking module 40 drives the tooling plate 20 loaded with the part to be detected 10 to descend back to the conveying module 32. Finally, the tooling plate 20 loaded with the part to be detected 10 flows into the next workstation.
[0059] Beneficial effects of testing equipment:
[0060] 1. The stand 314 is a marble platform that can ensure the accuracy of the entire structure;
[0061] 2. An XY two-axis manipulator 50 is used to adjust the camera position, and multiple fine-tuning mechanisms are used to satisfy both vertical adjustment and angle adjustment. The detection range of the two cameras is 5mm;
[0062] 3. The first driving assembly 315 for driving the second side plate 313 in the detection device adopts a linear motor. The position of the second side plate 313 can be adjusted, which can effectively be compatible with various sizes of the to-be-detected parts 10, and a threaded hole 3121 is opened on the top to install the cover plates 316 of different sizes to meet the compatibility of the to-be-detected parts 10 products;
[0063] 4. There are trays 33 on both the upper and lower layers of the conveyor belt 323, so that when the product 10 to be inspected flows through the water, the conveyor belt 323 will not sag due to gravity, which will affect the transmission efficiency;
[0064] 5. The device cover 80 inherits the touch screen, keyboard, PC analysis interface, etc., simplifying the appearance of the device.
[0065] In summary, the utility model adopts a machine to replace the previous manual labor. When the part to be inspected 10 is lifted up, the first camera component 62 and the second camera component 63 are driven by the manipulator 50. The first camera component 62 can take a picture of the appearance of the part to be inspected 10, and the second camera component 63 can take a picture of the part to be inspected 10 after being lit, and transmit the photographed information to the controller for analysis, so as to confirm the appearance of the part to be inspected 10 and the state after lighting. It saves time and effort, will not hurt the eyes, and on the basis of ensuring accuracy, it can meet the testing of different products, greatly reducing the compatibility problem of equipment during AOI production and improving production efficiency.
