[0002] A keyboard is an instruction and data input device used to operate a computer device, and also refers to a set of function keys arranged through a system to operate a machine or device. The keyboard is the most commonly used and main input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc. can be input into the computer, so as to send commands to the computer, input data, etc.; and in the production process of the keyboard, the assembly of keycaps is extremely important. The existing keycap assembly mechanisms basically meet the requirements, but there are still certain defects. Because there are many types of keyboard models, each model requires a separate mold cavity, resulting in high costs. Moreover, when changing the model during the production process, the mold cavity also needs to be replaced, affecting production efficiency; when assembling the keycaps, they need to be placed in the mold cavity according to specifications, and the size of the mold cavity needs to be enlarged to allow the keycaps to be placed at an inclination angle. It is easy to run out of position when the ejector rod levels, resulting in assembly failure or damage to the card slot and water droplet holes. Therefore, it is very necessary to design a keycap vertical pressing and assembling suction head mechanism for a keyboard module. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a keycap vertical pressing and assembling suction head mechanism for a keyboard module, so as to solve the defects of high cost, affecting production efficiency and easy to cause assembly failure or damage to the card slot and water droplet holes in the existing keycap assembly mechanism.

A pin 31 in the rotating shaft assembly 3 is sleeved in a slot hole opened on one side of the floating suction head seat 1. A spring sleeve 32 is sleeved on the pin 31. A suction cup head 4 is embedded and installed in a slot hole opened at the bottom of the floating suction head seat 1. A keycap 5 is adsorbed on the suction cup head 4. An air pipe joint 6 is embedded and installed in a slot hole opened on one side of the floating suction head seat 1. A suction head air pipe 7 is connected in cooperation with the air pipe joint 6. The rotating shaft assembly 3 is composed of a pin 31, a spring sleeve 32 and a tension spring 33. The tension spring 33 is sleeved on the spring sleeve 32. A fixing seat 8 is sleeved on the pin 31. The fixing seat 8 and the floating suction head seat 1 are connected in cooperation with each other through the pin 31. And limiting structures are provided on both the fixing seat 8 and the floating suction head seat 1. A fixing bolt 9 is sleeved in a through hole opened on the fixing seat 8.

[0022] Specifically, during use, first, by calculating the position offset of the keycap 5 and the water droplet hole 17 when the floating suction head seat 1 is at a specific angle and returns to horizontal after vertical pressing, the tension spring 33 is used to cause an inclination between the floating suction head seat 1 and the fixing seat 8. The inclination angle is limited by the provided limiting structure. Thus, when the floating suction head seat 1 is inclined, the card slot 18 is aligned with the outer shaft 13. When the floating suction head seat 1 continues to press down, the outer shaft 13 will actively slide into the card slot 18 during the process of the keycap 5 returning to horizontal. And the notch of the water droplet hole 17 of the keycap 5 will also be aligned with the inner shaft 14 due to the displacement during the process of returning to horizontal and then be pressed in. During the process, the entire module can complete the assembly work of the keycap 5 by vertical pressing. The assembly process is simple and the positioning accuracy is high, avoiding assembly failure or damage to the card slot 18 and the water droplet hole 17 on the keycap 5. When in use, there is no need to replace the mold cavity for keycaps 5 of different models. Then, multiple groups of modules are installed side by side on multiple side-by-side vertical cylinders or motor shafts, effectively improving the production efficiency and reducing the production cost.
