Description

Technical Field

[0001] The utility model relates to the field of keyboard detection devices, and particularly relates to a multi-station portable computer keyboard testing all-in-one machine. Background Art

[0002] At present, with the continuous improvement of people's living standards and the continuous progress of electronic products, portable PCs have become commonly used electronic products in people's life and work. With the popularization of tablet computers, since tablet computers are more portable than laptop computers, tablet computer manufacturers have begun to embed software APPs such as office and design in tablet computers to improve the productivity of tablet computers. As an indispensable keyboard for office work, it has also emerged accordingly.

[0003] For the detection of keyboards for tablet computers or laptop computers, since they have a touchpad more than conventional keyboards, during the detection process, the touchpad needs to be detected. At present, most of the keyboard detections for tablet computers or laptop computers are single-machine and single-function detections. After the conventional keyboard detection is carried out first, it is then transferred to the next station for touchpad detection, which reduces the production efficiency.

[0004] In addition, since the keyboard for tablet computers is thinner than the ordinary conventional keyboard in order to reduce the keyboard thickness, the stroke of its keys is much shorter than that of ordinary keyboards. Using the detection method of conventional keyboards can no longer meet its detection requirements. Therefore, it is urgent to develop a detection device that can be used for tablet computer keyboards. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi-station portable computer keyboard testing all-in-one machine aiming at the deficiencies of the prior art, and solve the problems that the existing keyboard detection devices have single functions and cannot detect the keyboards for tablet computers with short-stroke keys better.
