[0098] The conveying platform 201 equipped with two computer function keys 1400 and numeric keys 1500 is continuously conveyed by the circular conveyor 200 to the inspection module 700 to inspect whether the computer numeric keys 1500 are properly assembled on the computer function keys 1400. If the assembly is intact, the conveying continues. If the assembly is not intact, the machine is stopped and the defective products are removed.

[0099] After the inspection is completed, the conveying platform 201 equipped with the two computer function keys 1400 and the numeric keys 1500 is continuously conveyed by the circular conveyor 200 to the dust removal module 800 in sequence for surface dust removal of the computer keys;

[0100] After the dust removal is completed, the conveying platform 201 equipped with the two computer function keys 1400 and the numeric keys 1500 is continuously conveyed by the circular conveyor 200 to the screen printing module 900 for screen printing of the computer key surface marks;

[0101] After the screen printing is completed, the conveying platform 201 equipped with the two computer function keys 1400 and the numeric keys 1500 is continuously conveyed to the unloading position by the circular conveyor 200, and the two computer keys are sequentially transferred to the drying module 1000 for drying by the third transfer module 1100;

[0102] After the drying is completed, the fourth transfer module 1300 sequentially transfers the two computer keys to the unloading conveyor 1200 for final unloading, thereby completing all processing steps of the computer keys.

[0103] Above, refer to Figures 1 to 10 This utility model describes an automated assembly and silk-screen printing line for computer keys. Designed specifically for computer keys, it autonomously loads function keys 1400 and numeric keys 1500, precisely assembles them, and then performs silk-screen printing. The entire assembly-to-printing process requires no human intervention, significantly improving production efficiency and ensuring high-quality silk-screen printing output.
