AI Technical Summary
Existing keyboard conductive film testing devices lack an effective positioning structure, resulting in inconsistent detection positions and affecting the stability and accuracy of the test data.
A testing device was designed, comprising a frame, a worktable, a support plate, positioning bars, a C-shaped plate, and a swing assembly. The positioning bars and the C-shaped plate work together to achieve precise positioning and clamping of the keyboard conductive film, ensuring the consistency of the testing benchmark.
This technology enables rapid preliminary positioning and stable clamping of the keyboard conductive film, ensuring the accuracy and reliability of the test results and improving the stability of the test.
