[0025] Example 3: Please refer to Figure 9-Figure 15 On the basis of the second embodiment, a dustproof member 77 is provided in the air cavity 74 of the adsorption seat 72. The dustproof member 77 is composed of an upper annular plate 78, a first pipe 79, a first filter ball 80, a second pipe 81, a second filter ball 82, a top rod 83 and a lower annular plate 84. The upper annular plate 78, the top rod 83 and the lower annular plate 84 are welded.

The side walls of the first filter ball 80 and the second filter ball 82 are provided with filter holes 85. When the dustproof member 77 is actually installed, the upper annular plate 78 is in contact with the top surface of the air cavity 74. The lower annular plate 84 is set against the suction cup head 73, and the dustproof part 77 composed of the upper annular plate 78, the first pipe 79, the first filter ball 80, the second pipe 81, the second filter ball 82, the top rod 83 and the lower annular plate 84 is set in the air cavity 74 of the adsorption seat 72 on the keycap suction cup 56, so that the air intake area is effectively increased through the first filter ball 80 and the second filter ball 82, and the smaller filter hole 85 can prevent impurities from being sucked into the vacuum group 52 of the keycap mechanism, thereby ensuring the normal operation of the equipment, and the dust bucket 87 set on the edge of the filter hole 85 on the first filter ball 80 and the second filter ball 82 can prevent impurities from gathering at the edge of the filter hole 85, thereby avoiding the blockage of the filter hole 85, thereby ensuring the gas circulation efficiency.

[0026] The first pipe 79 and the second pipe 81 are both bellows, and the first filter ball 80 and the second filter ball 82 are both integrally formed with dust buckets 87 at the positions of the filter holes 85. The outer end diameter of the dust bucket 87 is smaller than the inner end diameter of the dust bucket 87. The first pipe 79 and the second pipe 81 adopt elastic bellows, so that the key cap suction cup 56 can cause a certain shaking effect on the first filter ball 80 and the second filter ball 82 during the up and down movement, thereby shaking off the dust accumulated on the first filter ball 80 and the second filter ball 82.

[0027] Working principle: the injection molding machine robot takes out the molded keycaps and drops them into the flip docking mechanism 2. The vacuum component 22 starts to vacuum the keycaps. After the flip docking mechanism 2 is actuated, the variable pitch cylinder 26 drives the variable pitch mechanism 28 to change the pitch of the keycaps in the X direction. The flip mechanism 25 is actuated, the flip lifting cylinder 21 descends, the vacuum component 22 starts the suction nozzle to break the vacuum, and the waste keycaps fall into the waste keycap collection mechanism 3, and fall into the waste collection bag below through the corresponding holes opened on the upper plate 32 of the discharge cylinder. The waste discharge completes the flip lifting. The cylinder 21 moves up, the transfer mechanism 4 moves to the bottom of the flip mechanism 25 through the transfer mechanism moving module 47, the flip lift cylinder 21 moves down, the vacuum component 22 starts to break the vacuum, the key cap falls into the profiling groove of the mold suction nozzle profiling plate 41, the flip lift cylinder 21 moves up, the Y direction variable pitch cylinder 43 moves along the Y axis direction to achieve the key cap in the Y axis direction The displacement correction, the transfer mechanism 4 moves to the bottom of the key cap suction mechanism 5 through the transfer mechanism moving module 47, and the key cap suction mechanism vacuum component 52 starts to absorb the vacuum The Z-axis cylinder 51 of the keycap suction mechanism descends to absorb the keycap in the film suction nozzle profiling plate 41, and the Z-axis cylinder 51 of the keycap suction mechanism rises. The transplanting mechanism 4 moves the mold to the bottom of the keycap suction mechanism 5 through the action of the transplanting mechanism moving module 47. The Z-axis cylinder 51 of the keycap suction mechanism descends, and the vacuum component 52 of the keycap suction mechanism starts to break the vacuum and put the keycap into the profiling groove of the mold suction nozzle profiling plate 46. The Z-axis cylinder 51 of the keycap suction mechanism rises, and the transplanting mechanism 4 moves the mold to the bottom of the keycap pressing mechanism 6 through the action of the transplanting mechanism moving module 47. The operator picks up the paint carrier from the discharge table 14 and puts it on the mold suction nozzle profiling plate 46, presses the two-handed start button 12 with both hands, and the Z-axis cylinder 61 of the keycap pressing mechanism moves down to buckle the keycap into the paint carrier. The Z-axis cylinder 61 of the keycap pressing mechanism moves up, and the operator takes the paint carrier out of the mold suction nozzle profiling plate 46 and puts it into the discharge table 14, and takes the product again for replacement operation. This equipment has a simple structure, strong applicability, simple operation, high yield rate and high production efficiency.
