Description

Technical fields:

[0001] This utility model relates to the field of testing equipment technology, and specifically to an automatic keyboard key detection machine. Background technology:

[0002] A keyboard is a device used for inputting commands and data to operate equipment. To ensure the quality of keyboard keys, reliability testing is required before they leave the factory to verify their reliability. Keyboard manufacturers typically test the sensitivity, durability, and response speed of the keys by simulating user operations. This helps ensure that each key functions properly and also allows for the measurement of parameters such as key force, travel distance, tactile feedback, and response time. By testing these parameters, it is possible to evaluate whether the key's operating force is appropriate, the travel distance is reasonable, the tactile feedback is comfortable, and the response speed is fast.

[0003] Currently available keyboard testing equipment can automatically test keyboard keys. For example, Chinese utility model patent application CN222212888U discloses a keyboard testing device, which includes: a worktable, a placement slot, a motor plate, a motor, a screw, a rotating plate, a moving block, a moving rod, a connecting block, and a pressing body. One end of the screw is detachably connected to the motor. The rotating plate is rotatably connected to the screw and located at the other end of the screw. The moving block is threadedly connected to the screw and located in the middle of the screw. The moving rod is fixedly connected to the moving block and located at the upper end of the moving block. The connecting block is slidably connected to the moving rod and located in the middle of the moving rod. The motor is started to drive the screw to rotate, causing the moving block to move the moving rod, thereby adjusting the position of the connecting block and the pressing body. After the position is adjusted, the pressing body is started to test the keyboard keys. This solves the problem of not being able to test the pressing life of keyboard keys, which may lead to unqualified keyboard keys and reduced yield.

[0004] However, this existing structure still has the following shortcomings:

[0005] In this technical solution, the pressing block is made to reciprocate up and down under the restriction of the pressing shell to press the keyboard keys, thereby detecting the pressing life. However, the pressing block can only test the vertical keys on the keyboard from top to bottom, and cannot test the horizontal keys, so its applicability needs to be improved.

[0006] In view of the above, the inventors propose the following technical solution. Utility model content:
