Technical Field

[0002] As a common input device, keyboards are widely used in the input of computers and various electronic devices. Keyboards are generally assembled from an aluminum substrate, a circuit board, a scissor support frame and keycaps. The keycaps are clamped on the substrate through the scissor support frame and are located above the corresponding keys. During the assembly process, various defects often occur, such as: failure to engage, insufficient clamping force, easy falling of the clamp, etc. These problems directly affect the consumer's operation. In order to avoid poor assembly of the keycaps, they need to be tested after installation to ensure that the keycaps can be firmly combined with the substrate. In the prior art, manual visual inspection is often used for detection, which is inefficient, inaccurate, and prone to errors and omissions, so we redesigned a keycap detection device.
