[0096] Multiple conveying platforms 201 are successively conveyed by the ring conveyor 200 to the feeding position of the function keys 1400 of the computer, and the first transfer module 400 successively places the function keys 1400 of two computers in the first feeding box 304 into the two storage slots 202 of the corresponding conveying platform 201;

[0097] The conveying platform 201 equipped with the function keys 1400 of two computers continues to be successively conveyed by the ring conveyor 200 to the feeding position of the numeric keys 1500 of the computer, and the second transfer module 600 successively places the numeric keys 1500 of two computers in the second feeding box 504 into the two storage slots 202 of the corresponding conveying platform 201 and assembles and snaps them onto the corresponding function keys 1400 of two computers to complete the assembly of the computer keys;

[0098] The conveying platform 201 equipped with the function keys 1400 and numeric keys 1500 of two computers continues to be successively conveyed by the ring conveyor 200 to the detection module 700 to detect whether the numeric keys 1500 of the computer are well assembled onto the function keys 1400 of the computer. When the detection shows good assembly, it continues to be conveyed. If the detection shows poor assembly, the machine stops to take out the defective products;

[0099] After the detection is completed, the conveying platform 201 equipped with the function keys 1400 and numeric keys 1500 of two computers continues to be successively conveyed by the ring conveyor 200 to the dust removal module 800 for surface dust removal of the computer keys;

[0100] After dust removal, the conveying platform 201 equipped with the function keys 1400 and numeric keys 1500 of two computers continues to be conveyed by the loop conveyor 200 to the screen printing module 900 in sequence for screen printing the surface identification of the computer keys;

[0101] After screen printing, the conveying platform 201 equipped with the function keys 1400 and numeric keys 1500 of two computers continues to be conveyed by the loop conveyor 200 to the unloading position in sequence, and the third transfer module 1100 transfers the two computer keys to the drying module 1000 for drying in sequence;

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

[0103] Above, with reference to Figures 1 to 10 A computer key assembly and screen printing line according to an embodiment of the present invention is described. This is an automated assembly and screen printing production line designed specifically for computer keys. It can independently complete the feeding tasks of the function keys 1400 and numeric keys 1500, accurately assemble the two together, and then perform the screen printing operation. The entire process from assembly to screen printing does not require manual intervention, thus significantly improving production efficiency and ensuring high-quality output of the screen printing process.
