[0002] Existing keyboard testing machines have limited functionality, only able to test one or two functions of the keyboard. If multiple functions need to be tested, multiple testing machines are required for multiple tests. After each test is completed, an operator needs to move the keyboard to another testing machine. This increases the testing time and reduces testing efficiency. In addition, damage to the test product is often caused during the handling and transfer process.

[0003] In addition, the existing keyboard screw-locking fixture and keycap pressing fixture are integrated into one machine, which solves the current common practice of manually screwing or using a separate screw-locking machine to screw mechanical keyboards, and expands the sharing of keyboard screwing process and keycap pressing machine.

[0049] The working principle of this keyboard assembly and testing all-in-one machine is as follows:

[0050] With power and ventilation supplied, all devices enter the standby state. The keyboard is placed onto the keyboard tray 7 manually or by a robotic arm. The keyboard first enters the key testing process, where the key testing device 3 performs a keystroke test. After the key testing process is completed, the turntable rotates 90° clockwise, and the keyboard enters the screw-fastening station.

The screw-fastening machine 44 conveys the screws to the screw feeder 45 via the X-axis slide rail, removes the screws, and transfers them. The screw-fastening machine 44 then drives the screws into the keyboard holes until every hole of the keyboard is screwed in.

[0051] The pressing device 52 is moved horizontally onto the keycap supply tray fixture 54. The pressing module 522 is driven by the driving device 523 to perform a pressing-raising action, picking up the keycaps from the keycap supply tray fixture 54 and transferring them above the keyboard fixture station. The pressing module 522 presses down to press the keycaps onto the keyboard. At the same time, the top plate fixture 533 on the lifting device 53 rises and cooperates with the pressing module 522 to press the keycaps onto the keyboard. After the keycaps are pressed, the turntable rotates 90° clockwise, and the keyboard enters the AOI test. The vision camera 61 on the AOI test device 6 captures the keyboard image. After the AOI test process is completed, the turntable rotates 90° clockwise back to the starting position, the keyboard is taken out, and the next keyboard is placed in to start the next cycle.
