This type of existing silicone button marking and printing equipment has the following problems: Manually positioning the mold during marking and printing is inaccurate, leading to reduced printing quality and affecting the identification of the correct silicone buttons during subsequent keyboard assembly.

[0023] The system also includes a positioning mechanism 8, which comprises an L-shaped bracket 82, a second slide groove 83, a slider 84, a support block 85, and a push block 86. The outer end of the support bar 2 is provided with a first slide groove 7. The inside of the first slide groove 7 is slidably connected to the left and right symmetrical L-shaped brackets 82. The upper end of the L-shaped bracket 82 is provided with a second slide groove 83 that is slidably opened. A slider 84 is slidably connected between two adjacent second slide grooves 83. The inner end of the slider 84 is provided with a support block 85. The inner end of the support block 85 is fixedly connected to the push block 86.

[0024] The positioning mechanism 8 further includes a drive assembly 81, which includes a lead screw 814 and an internally threaded cylinder 815. The lead screw 814 is rotatably connected to the outer wall of the upper end of the L-shaped bracket 82, and the internally threaded cylinder 815 is threadedly connected to the inner end of the lead screw 814.

[0025] The working principle of this utility model is as follows:

[0026] When marking and printing silicone buttons, the mold with the silicone buttons is first placed in the divider groove at the upper end of the conveyor belt 4. Then, the microcontroller 11 controls the operation of the motor 3 10. The output shaft of the motor 3 10 drives the input shaft at the left end of the cam divider 9 to rotate. In turn, the output shaft of the cam divider 9 drives the rotating shaft 3 on the right side to rotate. The rotation of the rotating shaft 3 drives the conveyor belt 4 to rotate intermittently, which in turn drives the mold with the silicone buttons in the groove to move to the right. Because the cam divider 9 ensures the intermittency of the conveying (after the first placement position is printed directly below the marking machine 6, the cam divider 9 can make the conveyor belt 4 drive the adjacent placement position to accurately be directly below the marking machine 6 and then stop intermittently), and the distance between each two adjacent placement positions is fixed and pre-adjusted so that the cam divider 9 can ensure that each placement position can be correctly conveyed to the marking machine 6.

[0027] When the mold of the silicone button moves to the area directly below the marking machine 6 on the conveyor belt 4, the microcontroller 11 will control the simultaneous operation of motor 1 811 and motor 2 813. When motor 1 811 operates, its output shaft drives the bidirectional lead screw 812 to rotate. The rotation of the bidirectional lead screw 812 will drive the L-shaped support 82 of the thread to move laterally towards each other inside the slide groove 1 7. Then, motor 2 813 operates, and its output shaft drives the lead screw 814 to rotate. The rotation of the lead screw 814 will drive the internal threaded cylinder 815 of the thread to move longitudinally towards each other, which will push the slider 84 to move longitudinally towards each other between the two slide grooves 2 83. Then, the push block 86 will be positioned by the support block 85.

[0028] Next, the microcontroller 11 controls the marking machine 6 to operate. The marking machine 6 uses external compressed air to drive its own needle to move at high speed. The needle impacts the surface of the silicone key and forms a dot matrix mark. The movement trajectory of the needle is controlled by its own mechanical device to complete the marking of text or patterns, so as to efficiently identify the corresponding silicone key specifications during subsequent keyboard assembly.

[0029] It is worth noting that in the embodiments disclosed above, motor 811, motor 813, cam separator 9, and motor 10 can all be KS-370, motor 813 can be YJ61, and cam separator 9 can be 180DF. The microcontroller 11 controls the operation of motor 811, motor 813, cam separator 9, and motor 10 using methods commonly used in the prior art.
