The lower end of the vision inspection cover 214 is detachably installed inside the upper end of the positioning groove 212.

[0020] The material sorting assembly 22 includes: a second electric hydraulic cylinder 221, a third electric hydraulic cylinder 225, a first pushing and separating plate 223, a second pushing and separating plate 224, a first collecting frame 226, a second collecting frame 227, and a welding plate 222. The inner side of the welding plate 222 is installed on the outer wall of the side of the detection support frame 216. The side of the first collecting frame 226 is set on the side of the detection table 1.

[0021] The specific implementation method is as follows: During testing, the lead frame is placed on the testing rotating disk 213.

In the unloading and sorting component 22, the second electric hydraulic cylinder 221 and the third electric hydraulic cylinder 225 drive the first pushing sorting plate 223 and the second pushing sorting plate 224 respectively, quickly and accurately sorting qualified and unqualified products into different collection boxes according to the inspection results, greatly improving production efficiency and reducing the labor intensity and time cost of manual sorting. The structural design of the welding plate 222 and the inspection support frame 216 enhances the stability of the entire device, ensuring that the components are not easily loosened or displaced during long-term operation, and improving the repeatability and reliability of the inspection.

[0022] The working principle of this utility model is as follows: During testing, the lead frame is placed on the testing rotating disk 213. The drive motor 211 drives the testing rotating disk 213 to rotate, so that the lead frame is accurately positioned in the positioning groove 212. The vision inspection cover 214 moves up and down through the first electric hydraulic cylinder 215 to adjust the testing height and ensure that the testing angle covers the key area of ​​the lead frame. After the test is completed, according to the test results, the second electric hydraulic cylinder 221 and the third electric hydraulic cylinder 225 drive the first pushing material distribution plate 223 and the second pushing material distribution plate 224 to move, pushing qualified products and unqualified products into the first collection frame 226 and the second collection frame 227 respectively.
