chip 7 absorb each other, the chip 7 already finishes the welding on the circuit board 13, at the moment, the absorption force of the sticking suction cup 911 is equal to the rebound force, no rebound occurs, at the moment, the tension sensor 912 is in a tensile state, the tension sensor 912 can read out the tension value, and if the chip 7 and the circuit board 13 are not welded, the chip 7 can rebound along with the sticking suction cup, this leads to the fact that the tension sensor 912 can't induce the tension value, through above characteristics, and in the use of equipment, only need observe whether tension sensor 912 has the tension value, can easily judge whether current chip 7 welds firmly, and this detection degree of difficulty that can very big reduction equipment.
In summary, when the circuit board chip mounter with automatic impurity removal of welding spots is used, firstly, a worker or a mechanical gripper works to put chips 7 needing to be subjected to chip mounting into the conveying pipe 601 from the feeding groove 602, the inner outline size of the conveying pipe 601 is consistent with the outer outline size of the chips 7, so that the chips 7 can be stacked in the conveying pipe 601, the layout site of the conveying pipe 601 at the bottom of the lifting plate 5 is consistent with the layout site of all the chips 7 on the circuit board 13, the chips 7 can realize the position positioning of the chip mounting points in the stacking process, after the chips 7 are stacked, the first rotating column 201 works to drive the pneumatic control seat 203 to move to the bottom end of the lifting plate 5 by the connecting plate 202, at this time, the sliding seat 4 slides outside the fixed column 3 and can drive the lifting plate 5 to move downwards, so that the conveying pipe 601 can move downwards and the pneumatic suction disc 204 moves to the inner side of the lifting plate, at this time, the motor 604 drives the screw rod 605 to rotate and can enable the pressing seat 606 to slide inside the sliding groove 603, so that the pressing seat 606 can squeeze the chip 7 and enable the chip 7 to pass through the baffle 607, the chip 7 can move to the top end of the pneumatic suction disc 204, at this time, the pneumatic suction disc 203 works to enable the pneumatic suction disc 204 to generate suction force, the chip 7 can be fixed by the pneumatic suction disc 204, and the chip 7 can still keep the position positioning of the patch point in the transferring process due to the one-to-one correspondence between the position of the pneumatic suction disc 204 and the conveying pipe 601;
then, after the chip 7 moves to the top end of the pneumatic chuck 204, the lifting plate 5 moves upwards to separate the material conveying pipe 601 from the pneumatic chuck 204, and at this time, the first rotating column 201 rotates to enable the pneumatic chuck 203 to drive the pneumatic chuck 204 to move to the bottom end of the patch seat 902, and at this time, the first electric push rod 804 works to enable the lifting seat 805 to drive the butt plate 806 to move downwards, so that the pneumatic chuck 204 can move to the inner side of the patch seat 902, and the attaching chuck 911 and the pneumatic chuck 204 absorb, the positions of the pneumatic chuck 204 and the patch seat 902 are in one-to-one correspondence, so that the chip 7 can move to the inside of the patch seat 902 under the state of keeping the position positioning of the patch point, and the operation is suspended by the pneumatic chuck 203, the suction force of the pneumatic suction cup 204 can be relieved, the chip 7 can be moved to be adsorbed by the attaching suction cup 911, the first electric push rod 804 moves upwards at the moment, the second rotating column 801 rotates, the patch seat 902 can be moved to the top end of the conveying belt 10, the conveying belt 10 works at the moment, the placement seat 11 provided with the circuit board 13 can be moved to the bottom end of the patch seat 902, the first electric push rod 804 moves downwards at the moment, the patch seat 902 can be contacted with the circuit board 13, the size of the plug head 807 at the bottom end of the abutting plate 806 is consistent with the size of the abutting groove 12 at the top of the placement seat 11, and the position accuracy of the patch seat 902 and the circuit board 13 can be ensured by inserting the plug head 807 into the inner side of the abutting groove 12;
then, after the bonding of the patch seat 902 and the circuit board 13 is completed, suction force can be generated in the coverage area of the circuit board 13 by the suction pump 903, impurities adhered on the surface of the circuit board 13 can be cleaned by suction force, the conditions of interference between the impurities and the chip 7 in the process of bonding or short circuit of the chip 7 caused by the impurities at the welding point position can be avoided, in addition, the bottom of the patch seat 902 can gradually become vacuum by the suction force, in the process of suction, the attached sucker 911 can slide downwards at the inner side of the patch seat 902 due to the influence of the suction force, the chip 7 can be gradually closed towards the circuit board 13, the attached sucker 911 can be blocked from moving downwards in the process of sliding downwards, at the moment, the suction force is increased by the suction pump 903, the attached sucker 911 can pass through the first flexible stopper 914 to continue moving downwards, the suction force of the suction pump 903 is increased when the solder paste in the solder paste storage tank 908 flows out of the solder outlet 909 due to the increased suction force and is smeared on the welding spot of the circuit board 13, after the solder paste is smeared, the suction force of the suction pump 903 is increased to the maximum, the attached sucking disc 911 can penetrate through the second flexible stop 915 to enable the chip 7 to be attached to the circuit board 13, and after the suction force of the suction pump 903 is increased to the maximum, the air heater 808 also works, so that hot air can contact with the chip 7 through the heat pipe 905, the hot air pipe 906 and the hot air port 907, under the blowing of hot air, the solder paste can be melted into solder liquid and is coated on the welding spot of the chip 7 and the circuit board 13, the air heater 808 pauses working, and the solder liquid is solidified, and the chip of the equipment is finished;
after the patch is finished, the second electric push rod 901 works, so that the bonding between the patch seat 902 and the circuit board 13 is released, the vacuum environment in the patch seat 902 can be released, at the moment, the bonding suction cup 911 can rebound along with the tension spring 910 due to the loss of vacuum suction, and therefore, the bonding suction cup 911 and the chip 7 are adsorbed, the chip 7 is welded on the circuit board 13, at the moment, the adsorption force of the bonding suction cup 911 is equal to the rebound force and rebound can not occur, and at the moment, the tension sensor 912 is in a tensile state, so that the tension sensor 912 can read out the tension value, and if the chip 7 and the circuit board 13 are not welded well, the chip 7 can rebound along with the bonding suction cup 911, so that the tension sensor 912 can not sense the tension value.
