Description

Technical Field

[0001] The utility model relates to the technical field of automated machinery, in particular to a keyboard axis testing machine. Background Art

[0002] Keyboards have keys that can be operated by users. The quality of the keys directly affects the user's control of the keyboard's functions. Therefore, testing the keys is a necessary process before the product leaves the factory. The traditional key test procedure is for a tester to press each key on the keyboard with his fingers. If each key pressed by the tester can be correctly identified and the corresponding operation is performed accordingly, it means that the key to be tested is normal. Otherwise, it means that the key to be tested is a defective product. However, the number of keys or keyboards to be tested is huge. If the test engineer only relies on manual keystrokes to perform all tests, not only will the test speed be slow and inefficient, but it may also cause omissions in the test.

[0003] More importantly, each performance of a key has a preset numerical specification, such as the key's support force range, the key's sensitivity to the pressing force channel, or the key's rebound force range, all of which need to meet the manufacturer's preset numerical specifications to provide users with a good user experience. However, manual testing can only judge the performance of the keys based on the test engineer's experience of hand feel, and cannot be quantified and replicated, resulting in slow progress in key testing and not being economically efficient. Moreover, the test engineer's subjective judgment cannot accurately test whether the key's performance falls precisely within the preset numerical specifications, resulting in different performance of each key. In addition, existing test machines can only test or detect a single function, which is inefficient and cannot achieve online flow testing.

[0004] Based on the above, it becomes a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content
