The positioning device of the IC card slot milling machine solves the problems that the IC card has low positioning adaptability, is easy to damage the IC card and is inaccurate in positioning in the height direction, realizes planar one-dimensional positioning by arranging a first side clamping jaw 4831 and a second side clamping jaw 4832, wherein the second side clamping jaw 4832 is flexibly connected through a lower reset spring group 486, avoids the damage of rigid impact on the IC card, and can adapt to IC cards with different widths; the end jaws 484 achieve positioning in another dimension in the horizontal plane; the backing plate 461 can be detached to replace different thicknesses, so that the IC cards with different thicknesses are suitable for milling grooves with different depths, and the IC cards are completely positioned by compressing after two-dimensional positioning is realized in a plane, so that the precision and the stability of groove milling are improved.

As shown in fig. 5, the vertical groove milling device 5 comprises a transverse cylinder 51, a longitudinal cylinder 52, an upright cylinder 53, a milling cutter assembly 54, an air blowing plate 55 and a suction cylinder 56; the transverse cylinder 51, the longitudinal cylinder 52 and the vertical cylinder 53 realize three-dimensional movement of the milling cutter assembly 54, the milling cutter assembly 54 is vertically arranged, a dust cover 57 is arranged at the lower end of the milling cutter assembly 54, the air blowing plate 55 is arranged at one end of the dust cover 57, and the air suction cylinder 56 is arranged at the other end of the dust cover 57.

When the vertical groove milling device 5 works, the milling cutter assembly 54 reaches a specified position under the adjusting action of the transverse cylinder 51, the longitudinal cylinder 52 and the vertical cylinder 53, the milling cutter starts to rotate, meanwhile, the air blowing plate 55 starts to blow air, the air suction cylinder 56 starts to blow air, and the broken powder is sucked away.

The air blowing device 6 is provided with an air outlet, the position of the air outlet is over against the groove of the IC card, and the height of the air blowing device 6 can be adjusted.

When the IC card slot milling machine works, the IC card slot milling machine is processed through the following steps in sequence:

feeding: the traversing cylinder 219 stretches out and draws back, the turntable 211 is driven to rotate through gear and rack transmission, then the positioning cylinder 222 drives the positioning block 223 to extend out, the positioning block 223 is clamped on the V-shaped hole 2111 on the turntable 211, positioning is achieved, then the material guiding cylinder 232 drives the sucker 231 to ascend, on one hand, the IC card at the bottom end of the bin plate 216 is sucked, on the other hand, the IC card is lifted up, the clamping blocks 217 are tilted upwards under the action of spring force, the IC card can pass through the clamping blocks 217, and then the IC card passes through the rubber block 218 to be pulled out downwards, so that the IC card on the upper layer is kept; when all the IC cards on one side of the turntable 211 are taken out, the positioning mechanism 22 is released, and the traverse cylinder 219 drives the turntable 211 to rotate one hundred eighty degrees, so that the IC cards on the other side are loaded; the IC card conveying device 3 conveys the IC card;

(II) positioning and clamping: after the IC card reaches the position above the base plate 461, the driving cylinder 482 drives the lifting plate 485 to descend, so that the first side clamping jaw 4831, the second side clamping jaw 4832 and the end clamping jaw 484 all rotate upwards, the end clamping jaw 484 pushes the IC card to the side material passing plate 45 to realize positioning, and the first side clamping jaw 4831 and the second side clamping jaw 4832 clamp the IC card together; after the IC card is positioned and clamped, the lifting cylinder 44 drives the lifting seat 43 to integrally lift up, so that the IC card is pressed on the cover plate 47, and the complete fastening of the IC card is realized;

(III) groove milling: the milling cutter assembly 54 reaches a designated position under the adjusting action of the transverse cylinder 51, the longitudinal cylinder 52 and the vertical cylinder 53, starts to rotate the milling cutter, meanwhile, the air blowing plate 55 starts to blow air, the air suction cylinder 56 starts to blow air, and the broken powder is sucked away;

(IV) removing impurities by blowing: the blowing device 6 blows away the residual broken powder on the IC card of the well-washed groove through an air pump;

(V) collecting and blanking: the IC card conveying device 3 conveys the IC cards to the end, and the IC cards sequentially fall into the collection box 7 to be collected.
