[0055] For details, please refer to Figure 1-Figure 8 The clamping mechanism includes a side clamping block 303, a first circular hole 305, a second circular hole 306, a first connecting rod 307, a first spring 308, a second connecting rod 309, a second spring 310 and a buffer plate 313. The first circular hole 305 and the second circular hole 306 are opened on the inner wall of the C-shaped block 302, the second connecting rod 309 is located in the second circular hole 306, the first connecting rod 307 is located in the first circular hole 305, the buffer plate 313 and the side clamping block 303 are located in the C-shaped block 302, the second spring 310 is fixedly connected to the surface of the buffer plate 313, the first spring 308 is fixedly connected to the surface of the side clamping block 303, the first spring 308 is sleeved on the surface of the first connecting rod 307, and the second spring 310 is sleeved on the surface of the second connecting rod 309.

[0058] In this embodiment: the circular groove 304 is used to accommodate the first cylinder 311. When the tested component needs to be pushed out, the first cylinder 311 is actuated to realize the movement of the push piece 312 through its extension and contraction. The push piece 312 will move along the set direction, thereby pushing the tested component out of the test position.

[0059] For details, please refer to Figure 1-Figure 8 The inner wall of the C-shaped block 302 is fixedly connected with a protrusion 10, and the material of the protrusion 10 is rubber.

[0067] For details, please refer to Figure 1-Figure 8 The material of the finished product display box 6 is rubber, and the surface of the protective shell 4 is coated with an antistatic coating.

[0068] In this embodiment: the rubber material has good elasticity, wear resistance and impact resistance, which can effectively prevent the finished components from being damaged during the collection process.

[0071] The working principle and use process of the present invention are as follows: the capacitor or inductor element to be tested is placed in the C-shaped block 302, the slider 301 moves along the linear transport rail 2, and the sliding placement block 502 containing the element to be tested is brought to the test position, and the capacitor tester 510 is pushed downward by the third cylinder 508, so that the capacitor tester 510 contacts the positive and negative contact sheets 505, and then the second cylinder 506 pushes the sliding placement block 502 downward, so that the positive and negative contact sheets 505 contact the capacitor, and the capacitor tester 510 contacts the element through the positive and negative contact sheets 505, and starts to test the capacitance value. After the test is completed, the system confirms whether the element is qualified, thereby improving the test efficiency and the automation level of the production line. This process is suitable for automated production lines that require frequent testing and rapid removal of finished components, especially for testing components that are sensitive to static electricity.
