Example
[0021] like Figure 1-2 As shown, an automatic PIN clamping carrier for keyboard feel testing includes a test seat and a cover plate 5. The test seat includes a bottom mold 1 and a vertical plate 2. The bottom mold 1 is provided with a groove 11 and an avoidance groove 12. The groove 11 is used to place the product to be tested 6. The vertical plate 2 is fixed directly below the avoidance groove 12. The cover plate 5 is provided with a key hole 51 and a pressing block 52. The key hole 51 is arranged corresponding to the key of the product to be tested 6; as shown Figure 3 As shown, the vertical plate 2 is fixedly mounted with a limit block 21 and a guide member 22, and the spacing between the limit block 21 and the guide member 22 is just enough to pass through the pressing block 52. When the cover plate 5 is closed, the pressing block 52 moves downward to between the limit block 21 and the guide member 22, and folds and fits the interface end of the film 61 of the product to be tested 6 onto the vertical plate 2. The limit block 21 and the guide member 22 are provided to limit and guide the downward movement of the PCB board 31, so that the alignment of the interface end of the film 61 is more accurate, and the reliability of the product test results is higher.
[0022] like Figure 1-3 As shown, the test seat also includes a mounting plate 3 and a driving member 4. A PCB board 31 is fixed on the mounting plate 3. The driving member 4 can drive the mounting plate 3 to move so that the PCB board 31 contacts the interface end of the soft film 61. A silicone gasket 23 is also provided on the vertical plate 2. The silicone gasket 23 is used to avoid direct contact between the PCB board 31 and the vertical plate 2, prevent the PCB board 31 from being damaged by impact, and increase the service life of the PCB board 31.
