Description

Technical Field

[0001] The present invention relates to the technical field of keyboard assembly, and in particular to a keyboard assembly device. Background Art

[0002] The keyboard production process requires the manufacture of the casing, circuit board and keys first. When all the parts are manufactured, they are assembled according to a certain process to obtain a keyboard. The installation process of the keyboard can be carried out by automated equipment, which saves a lot of labor. The working principle of the keyboard is to send an electrical signal from the shaft by tapping the key, and send the electrical signal to the computer through the circuit board to complete the key input. Therefore, the cleanliness of the keyboard circuit board and the connection between the shaft and the circuit board is very important. If dust falls on the circuit board or enters the connection between the shaft and the circuit board, it may cause poor contact when the keyboard is used, and the tapping cannot output a signal, or output an incorrect signal.

[0003] Currently, during keyboard production, the installation of switches and keys is mostly carried out through a keyboard installation device. After the circuit board is installed on the keyboard casing, the switches and keys are automatically installed in sequence on the installation device. However, during this process, the front of the keyboard faces upward, and the gap between the circuit board and the keyboard casing faces upward.

Then, multiple clamping plates 22 can clamp keyboards of various sizes. The clamping plate 19 presses the keyboard on the clamping plate 22 to prevent the keyboard from shaking. The driving cylinder 4 27 moves to the accessory feeding device 28 to obtain the case or shaft, and then rotates 180 degrees and moves to the designated position for installation.
