The top of the assembly platform 23 is also equipped with a first vacuum suction cup 24 and a first positioning pin 25. One side of the first translation mechanism 21 is also equipped with a first vacuum suction cup 24 and a first positioning pin 25. A platform cleaning component 4 is provided; the special key assembly mechanism 3 includes a first mounting frame 31, a Y-axis translation mechanism 32 mounted on the first mounting frame 31 along the translation direction of the first translation mechanism 21, an X-axis translation mechanism 33 connected to the Y-axis translation mechanism 32, and a Z-axis lifting mechanism 34 connected to the X-axis translation mechanism 33; the Z-axis lifting mechanism 34 is also driven to connect a Z-axis lifting frame 35; the Z-axis lifting frame 35 is arranged above the assembly platform 23, and the bottom of the Z-axis lifting frame 35 is also equipped with an enter key assembly mechanism 36 and a direction key assembly mechanism.

[0015] In this embodiment, the positioning platform mechanism 1 is used to position the keys to be assembled (in this embodiment, mainly the four arrow keys, Enter key, and Ctrl key). After positioning, the special key assembly mechanism 3 transfers the corresponding keys and assembles them into the corresponding positions on the keyboard frame. The first translation mechanism 21 in the assembly platform mechanism 2 (the first translation mechanism 21 adopts a motor lead screw transmission method) drives the first translation frame 22 and the assembly platform 23 to move, so that the keyboard reaches the preset assembly position. The first vacuum suction cup 24 on the assembly platform 23 can adsorb the keyboard frame to prevent it from shifting during key assembly and improve assembly accuracy. The first positioning pin 25 on the assembly platform 23 can quickly position the keyboard frame. At the same time, the platform cleaning component... 4. The assembly platform 23 can be cleaned before each assembly to remove dust and other impurities, ensuring that the keyboard frame is placed flat on the assembly platform 23. The Y-axis translation mechanism 32, X-axis translation mechanism 33 and Z-axis lifting mechanism 34 of the special key assembly mechanism 3 can all use existing linear modules. With the cooperation of the three, the Enter key assembly mechanism 36 and the arrow key assembly mechanism can be driven to perform translation and lifting movements, which facilitates the assembly of the corresponding keys. In addition, in this embodiment, the bottom of the Z-axis lifting frame 35 is also equipped with a Ctrl key assembly mechanism. The structure and working principle of the Ctrl key assembly mechanism are similar to those of the Enter key assembly mechanism 36 (refer to the working principle description of the Enter key assembly mechanism 36 below), which will not be repeated here.

[0016] In one embodiment, the platform cleaning component 4 includes a cleaning base 41, a first upright 42 mounted vertically on the cleaning base 41, and a cleaning air blowing seat 43 mounted on the first upright 42.

[0018] A first suction nozzle 365 is installed in the first slot at the bottom of the first assembly base 364. It can pick up the Enter key by vacuum adsorption. Then, driven by the first lifting cylinder 362, the first lifting base 363 is driven to descend, thereby assembling the key into the corresponding position on the keyboard. At the same time, the first slot is opened at an upward angle. During assembly, one side of the key can be installed in the corresponding position on the keyboard first. Then, the first pressing cylinder 366 drives the first pressure plate 367 to descend, so that the other side of the key is pressed into the corresponding position on the keyboard by the first pressing block 368, thereby improving assembly efficiency and accuracy.

[0020] The three second nozzles 374 are used to pick up and assemble the left, down and right arrow keys respectively. The assembly process is the same as that of the Enter key assembly mechanism 36 mentioned above, and will not be repeated here. The second assembly module 38 is used to assemble the up arrow key. The structure and working principle of the second assembly module 38 are similar to those of the first assembly module 37, and will not be repeated here.
