Problems solved by technology

When the keyboard is used for a long time or improperly, the keycaps are easy to fall off and the keyboard cannot be used, which causes great inconvenience to the user. Therefore, the keyboard needs to be tested before leaving the factory.
At present, the commonly used keycap detection methods are all manually detected. However, manual detection is prone to problems such as missed detection and false detection, which leads to insufficient reliability of keycap detection.

Embodiment Construction

[0026] Please refer to figure 1 , which shows the keycap detection device 1 in one embodiment of the present invention. The keycap testing device 1 is used for testing a keycap 200 of a keyboard 2 to be tested. Please also refer to figure 2 , the keycap detection device 1 includes a processing unit 10 , a light source 20 , a camera unit 30 , a probe unit 40 , a carrying portion 50 and a storage unit 60 .

[0027] The probe unit 40 includes a probe card 401 and a plurality of probes 402 with the same length. In this embodiment, the probe 402 is T-shaped. The probe card 401 is provided with a plurality of through holes (not shown) for accommodating the probes 402 . Each probe 402 passes through a through hole and is movably fixed on the probe card 401 . The probe 402 can move up and down when receiving an external force, and after removing the external force, the probe 402 maintains the moved state. In this embodiment, each keycap 200 corresponds to a preset number of pro...

Abstract

The present invention provides a keycap detection device and detection method, the device includes a processing unit, a light source, a camera unit, a probe unit and a storage unit, the processing unit includes a light source opening module, the light source is turned on in response to an opening operation; a first control module , when the light source is turned on, the probe unit is controlled to descend until each probe touches the keyboard to be tested; the camera module is used to control the camera unit to take pictures of the plurality of probes at the first detection position; the calculation module, according to The image taken and the images of the multiple probes at the reference position calculate the height difference between each probe at the first detection position and the reference position; the calculation module also calculates the difference between the maximum height difference and the minimum height difference The first inclination value of the corresponding keycap is obtained by the difference between them; and the determination module determines that the detection of the keyboard to be tested fails when the first inclination value of a keycap is greater than a preset value. The invention effectively improves the reliability of keycap detection.

Description

technical field [0001] The invention relates to a keycap detection device and a detection method. Background technique [0002] As a common input device, the keyboard is widely used in the input of computers and various electronic devices. When the keyboard is used for a long time or improperly, the keycaps are easy to fall off and the keyboard cannot be used, which causes great inconvenience to the user. Therefore, the keyboard needs to be tested for the keycaps before leaving the factory. At present, the commonly used keycap detection methods are all manually detected. However, manual detection is prone to problems such as missed detection and false detection, which leads to insufficient reliability of keycap detection. Contents of the invention [0003] In view of this, it is necessary to provide a keycap detection device and detection method to solve the above technical problems. [0004] The invention provides a keycap detection device for detecting a keycap of a ke...
