Shown in Fig. 2,3, the utility model mainly is that the front side end at board 20 is provided with feeding mechanism 30, is provided with roller set 40, several nozzle sets 50 and several cleaners 60 in the board 20, and board 20 rear side end are provided with discharging mechanism 70; Wherein:

Board 20 (shown in Fig. 2,3), it is the housing that is made of metal, and is equipped with a sheet 21 in forward and backward side, in order to inspecting, keeping in repair.

Feeding mechanism 30 (shown in Fig. 4,5), it is that group is established feeding web 32 in the mounting 31 of a Qian shape, this feeding web 32 is to be attached to board 20 inside, sets up two symmetrical follower arms 33 again in mounting 31 tops.This follower arm 33 can supply some integrated circuit 10 horizontal positioned, again in follower arm 33 lower edges, feeding web 32 upper limbs, be provided with telescopic two retaining pin 34 and telescopic blanking plates 35, this two retainings pin 34 is the height a little more than blanking plate 35, and two retaining pins 34 and the flexible of blanking plate 35 are to be finished by the transmission of a pneumatic cylinder 36.Again, set firmly a prerotation vane 37 in feeding web 32 terminal tops, these prerotation vane 37 root edges are provided with circular-arc guide groove.(shown in Fig. 6,7) whereby, several integrated circuit 10 levels can be placed between two follower arms 33, because of two retaining pins 34 stretch once, can make an integrated circuit 10 bearings in blanking plate 35 upper limbs, blanking plate 35 is flexible immediately once to make bearing fall within feeding web 32 tops in the integrated circuit 10 of blanking plate 35 upper limbs because of its contraction, and moves forward with the feeding web 32 that rotates, again through the guiding of prerotation vane 37, and make it enter board 20 inside with correct angle.

Roller set 40 (shown in Fig. 3,8,9), it is to be made of row's upper roller 41 and row's bottom roller 42, this upper roller 41 and bottom roller 42 are to be symmetry shape, and (technology by the some rollers of motor transmission is a located by prior art to make upper roller 41 and bottom roller 42 reverse sync transmissions by the transmission of the drive motor of board 20 rear sides, so seldom give unnecessary details at this), 42 of this upper roller 41 and bottom rollers have a spacing, and integrated circuit 10 is held wherein, and owing to the rotation of upper roller 41 and bottom roller 42 drives integrated circuit 10 reaches; Again in the latter half of material-blocking belt 43 that is arranged with of bottom roller 42.

Several nozzle sets 50 are (as Fig. 3,8, shown in 9), this nozzle sets 50 can be mounted on the top of first half upper roller 41, the position of the below of bottom roller 42 and latter half of bottom roller 42 belows, this nozzle sets 50 is made up of several nozzles 51, make each nozzle 51 all towards the direction of roller, and be positioned at the gap of roller and roller and establish, this nozzle sets 50 can pumping because of submerged pump, and making water liquid and glue-dispenser simultaneously by nozzle 51 ejections, the glue slag 14 that residues in conduction foot rest 13 after making water liquid that nozzle sets 50 sprayed and glue-dispenser to the glue shell 11 of integrated circuit 10 1 end faces and encapsulation imposes spray and removes operation.In addition, nozzle sets 50 its nozzles 51 of being located at the roller first half are the conduction foot rests 13 corresponding to integrated circuit 10, then, carry out removing work at the glue slag 14 on the conduction foot rest 13, and nozzle sets 50 its nozzles 51 of being located at the latter half of below of roller are the glue shells 11 corresponding to integrated circuit 10 lower surfaces, and grind the glue operation at this glue shell 11.Especially (shown in Figure 10,11), being arranged at bottom roller 42 latter half of material-blocking belts 43 is that conduction foot rest 13 is covered, and when making nozzle 51 ejection water liquid and glue-dispenser, can not be sprayed onto conduction foot rest 13.

Several cleaners 60 (shown in Fig. 3,8,9), this cleaner 60 has an air nozzle 61 and a water nozzle for liquid 62, and be arranged at appropriate location in the board 20, and make air nozzle 61 and water nozzle for liquid 62, and be positioned at the gap of roller and roller and establish all towards the direction of roller.Cleaner 60 can be because of the pumping of air compressor machine and pump, and make air and the ejection of water liquid, makes it impose cleaning operation to integrated circuit 10.

Discharging mechanism 70 (as shown in figure 12), it is that group is provided with discharging conveyer belt 72 in the mounting 71 of a Qian shape, and these discharging conveyer belt 72 1 ends are to be attached to board 20 inside, and discharging conveyer belt 72 end in addition then is connected a reclaiming plate 73.

Composition by above-mentioned member, integrated circuit 10 levels that can several are pending are placed between two follower arms 33, stretch once by two retaining pins 34, can make an integrated circuit 10 bearings in blanking plate 35 upper limbs, blanking plate 35 is flexible immediately once, make bearing fall within feeding web 32 tops because of its contraction in the integrated circuit 10 of blanking plate 35 upper limbs, integrated circuit 10 is moved forward with the feeding web 32 that rotates one by one, again through the guiding of prerotation vane 37, and make it enter board 20 inside with correct angle.After integrated circuit 10 enters board 20 inside, promptly enter in the spacing of upper roller 41 and bottom roller 42, integrated circuit 10 is moved forward because of the rotation of two-wheeled, when integrated circuit 10 moved forward to roller set 40 first halfs, water liquid and glue-dispenser that nozzle sets 50 is sprayed imposed spray except that operation to the glue slag 14 that integrated circuit 10 residues in conduction foot rest 13.When integrated circuit 10 moves forward to roller set 40 when latter half of, can make the glue shell 11 of 50 pairs of integrated circuit 10 lower surfaces of nozzle sets grind the glue operation, to conduct electricity foot rest 13 and cover because of being arranged at bottom roller 42 latter half of material-blocking belts 43 again, and make nozzle 51 ejection water liquid and glue-dispenser can not be sprayed onto conduction foot rest 13.Moreover this integrated circuit 10 is rotated by upper roller 41 and bottom roller 42 and in the process of reach, can be by the sprinkling of the air nozzle 61 and the water nozzle for liquid 62 of several cleaners 60, and then integrated circuit 10 imposed cleaning operation.When integrated circuit 10 is finished cleaning and is subjected to upper roller 41 and the transmission of bottom roller 42 and when shifting out board 20, promptly be attached to the discharging conveyer belt 72 of discharging mechanism 70, and continue and sent by reclaiming plate 73.

From the above mentioned as can be known, because the work of cleaning integrated circuit 10, mainly by several nozzle sets 50 ejection water liquid and glue-dispensers, and being imposed spray, the glue slag 14 that residues in conduction foot rest 13 after the glue shell 11 of integrated circuit 10 1 end faces and the encapsulation removes operation, making this spray remove operation finishes in the environment with water liquid, so can avoid producing static in the operation process, and then make integrated circuit 10 unlikely damages.Again because of the cooperation of above-mentioned all mechanism, element, and the global purge operation is finished smoothly.

From the above and embodiment shown in the drawings as can be known, the utility model really can reach its its intended purposes, and have significant practicality and progressive, and the technological means of its utilization and structural feature really form for this case creator at first researches and develops, meet novel patent requirement, so file an application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
