[0025] Example 1
[0026] This embodiment is the first embodiment of the parts inspection device, such as... Figure 1 , Figure 3 As shown, the system includes a frame 1, a positioning fixture, a detection camera 2, a display screen 3, and a control system. The frame 1 is equipped with a detection table 101. The positioning fixture is detachably installed on the detection table 101 and is used to position and place the part 11. The detection camera 2 is installed on the frame 1 and is used to take pictures of the part 11 placed on the detection table 101. The detection camera 2 and the display screen 3 are respectively connected to the control system. There are at least two sets of positioning fixtures. The positioning fixture includes a base 4 and a positioning pin 5 for positioning the part 11. The positioning pin 5 is detachably connected to the base 4, and the other end of the base 4 is detachably connected to different positions on the detection table 101.
[0027] In use, the aforementioned parts inspection device, according to the positioning requirements of parts 11 of different specifications, installs at least two sets of positioning fixture bases 4 at different positions on the inspection table 101, and installs positioning pins 5 on the bases 4 so that the positioning pins 5 correspond to the positioning holes of the parts 11, positioning the parts 11 on the inspection table 101. The control system controls the inspection camera 2 to take pictures and receives the pictures taken by the inspection camera 2. The received pictures are compared and analyzed with stored standard parts, and the inspection results are transmitted to the display screen 3 for display, improving inspection efficiency and the accuracy of inspection results. In this embodiment, through the detachable connection between the base 4 and the inspection table 101, and the detachable connection between the base 4 and the positioning pins 5, the positioning fixture can be applied to the positioning and placement of parts 11 of different specifications for inspection, reducing production costs and improving economic efficiency.
