Fall-off detector

Abstract

The invention discloses a fall-off detector which is used for detecting keycaps of a keyboard. The fall-off detector comprises a base, a moving bracket as well as a testing structure and a limiting structure which are arranged on the moving bracket; when the moving bracket moves from a first end of the keyboard to a second end of the keyboard relative to a to-be-tested device, the testing structure and the limiting structure are enabled to move from the first end to the second end relative to the to-be-tested device, in the moving process, the testing structure applies force in a first direction to a to-be-tested component, the limiting structure limits movement of the to-be-tested device in the first direction under the force in the first direction, and the testing structure and the limiting structure act on the same to-be-tested component at different moments, that is, the condition of reduction of the detection rate due to bringing up of the stressed keyboard during testing can be avoided, and the detection missing risk is reduced.

Description

technical field [0001] The invention describes a fall-off detector, especially a fall-off detector for detecting a keycap of a keyboard. Background technique [0002] Generally speaking, the keycaps will fall off due to poor assembly and insufficient binding force. Detachment requires a pull-out force test for each keycap, that is, it is necessary to check the combination of each keycap one by one, so as to ensure the quality of the keyboard. [0003] When detecting the combination of the keycap, it is necessary to provide a preset pulling force to the keycap. If the keycap under the force does not fall off, it means that the combination of the keycap is good. Otherwise, it means that the combination is good. not to standard. However, during the detection process, the keycaps will be pulled up by the pulling force and the entire keyboard will be lifted. This situation will make the keycaps with unqualified combination unable to be detected, resulting in a low detection rat...

AI Technical Summary

Problems solved by technology

However, during the detection process, the keycaps will be pulled up by the pulling force and the entire keyboard will be lifted up. This situation will make the keycaps with unqualified combination conditions unable to be detected, resulting in a low detection rate. The reliability of the product is reduced, which in turn reduces the product quality, and cannot meet the strict quality requirements of customers and consumers.
