Description

Multi-type keyboard automatic test device

The present invention relates to a keyboard automatic testing device, especially a device capable of automatically testing the functions of key presses, volume knobs and light signal display functions of electronic equipment that can automatically test various key layout types-multi-type keyboard automatic testing device

Press, keyboards have been widely used in various electronic devices as peripheral devices for controlling commands or data input of electronic devices, such as: common personal computers, industrial controllers, cash registers... and other electronic devices with information input functions Therefore, the quality of the keyboard and whether it can be operated normally will directly affect the operation stability of the electronic device. Moreover, the most direct operating unit in the keyboard is the key, so the test of the key is really important for the keyboard. An important part.

However, traditionally, the testing of keyboard keys in the general industry is manual, that is, pressing each key in the keyboard one by one manually, which is not only time-consuming and labor-intensive, but also has low test efficiency; In the test method of pressing the keys, due to the different pressing forces or the uneven force on the surface of the key cap, misjudgments are likely to occur, which makes the test quality of the keyboard even worse. Moreover, when testing a variety of different In the state of key-type keyboards, such as mechanical contact keyboards and capacitive film keyboards, there is an obvious difference in the pressing force between the two. The conventional manual pressing test one by one will make the tester need to press the fingertips. It is very difficult to adjust and change at any time. At the same time, during the test process, it is easy to cause excessive pressure changes, which greatly increases the probability of misjudgment and seriously affects the quality control of keyboard products.

In addition, in the conventional keyboard test, in addition to the inconvenience of manually pressing the above-mentioned keyboard keys, it also lies in the aspect of keyboard testing for different brands or types. The increase of button components and different layout positions make it necessary for the testers to adapt and change the test mode one by one for the keyboards of different types and brands when testing the keyboard. become more sluggish.

The main purpose of the present invention is to provide a multi-type keyboard automatic testing device, which can automatically test the key pressing and light signal display of each keyboard one by one by means of air pressure pressing, saving manpower and working hours of keyboard testing, and further improving health. disk test efficiency;

Another object of the present invention is to provide a multi-type keyboard automatic testing device. The output pressing force of the test pressing keyboard is output in the form of air pressure so as to achieve a uniform effect, so that each key press can be tested The force is uniform, reducing the probability of misjudgment, so as to improve the quality of keyboard testing.

Another object of the present invention is to provide an automatic testing device for multi-type keyboards. The force of pressing the keyboard can be precisely adjusted and controlled by air pressure to meet the keyboard test of different pressing forces.

Still another object of the present invention is to provide a multi-type keyboard automatic test device, which has a replaceable test module, which can target the special function keys and display lights arranged on keyboards of different brands and types. And the volume knob and other components are arranged for corresponding test components, which can be used for automatic testing of keyboards of various brands and types.
