Key testing mechanism

Abstract

The invention discloses a key testing mechanism, and the mechanism comprises a workbench, a portal frame support, an X-ray movement mechanism, a Z-axis movement mechanism, and a product carrier. The portal frame support and a Y-axis movement mechanism are disposed on the workbench. The X-axis movement mechanism is disposed on the portal frame support. The Z-axis movement mechanism is disposed on the X-axis movement mechanism. The product carrier is disposed on the Y-axis movement mechanism. The Y-axis movement mechanism can move back and forth on the workbench. The Z-axis movement mechanism can move left and right on the X-axis movement mechanism. The Z-axis movement mechanism is also provided with a detection module group. According to the scheme of the invention, the comfortableness of a conventional key is quantified, and the whole triggering process of the key is effectively reflected in a mode of curve coordinates through a press stroke and a bounce force. The mechanism detects the maximum bounce force and the minimum bounce force of the key and the downward pressing displacements of all feature points in a press process, thereby facilitating the quality control of a production process.

Description

technical field [0001] The invention relates to a button testing mechanism, which belongs to the button detection in the fields of computers, automotive electronics and consumer electronics. Background technique [0002] As an important part of the computer, the computer keyboard key must first ensure the effectiveness and accuracy of the user's input operation on the key, and at the same time ensure the comfort of the user's keystrokes (from the rebound resistance of the key during the keystroke process). Decide). According to the development and evolution of keyboard key detection in the industry, it can be roughly divided into two generations at present. The first generation of key detection is manual detection. qualified. The second generation of key detection is weight detection, through which the weight of the standard weight is automatically pressed down, and the key that can be triggered is a qualified key, and the key that cannot be triggered due to excessive resi...

AI Technical Summary

Problems solved by technology

Both of the above-mentioned methods have deficiencies: the first generation of manual detection is slow, and the comfort of the keys cannot be quantified by the operator's hand feeling, which is likely to cause misjudgments or missed judgments of defective products; the second generation of weight detection can only The pressure of a single weight is tested, and the button with a resistance greater than this weight is judged as bad, but the disadvantage is that the button with too small resistance cannot be detected, and the displacement during the pressing process cannot be detected, so this solution still cannot Fully reflect the user's tactile comfort during the keystroke process
