The θ axle motion of this scheme each drive suction nozzle front end assemblies A1 and B1 rotation to realize by stepping motor F1, a F2, adopts wedge shape sheave G1, G2+ and wedge shape belt H1, H2 transmission.
Its airtight gas circuit adopts top-down closed conduct I1, I2 to be connected with external vacuum generator, between suction nozzle front end assemblies A1, B1 and closed conduct, adopts snap joint J1, J2 to be connected.
Its workflow is, the total member A of suction nozzle, B is arranged on straight line module K, straight line module K is moved to feeding pallet L top, cam C rotating alternately presses down A, B, make A, B alternately contacts corresponding element, by vacuum suction by component pick-up, and keep adsorbed state by vacuum, then straight line module K is by A, B moves to pcb board top to be mounted, cam C rotating alternately presses down A, B, element is contacted with the tin cream of pad locations on pcb board, viscosity by tin cream overcomes vacuum suction makes element separated in suction nozzle, and be mounted on appointment pad locations.So repeatedly, complete the electronical elements surface attachment process to whole pcb board.
The initial angle that the angle that need to mount as element is put in charging tray with element is different, after A, B stick electronic components, θ axle electric rotating machine F1, F2 can rotate a certain angle, by wedge shape belt, drive suction nozzle to rotate, to reach rotating electron element angle and the corresponding object that mounts requirement.
B: the scheme of Dual-Servo Motor system+airtight gas circuit
Be different from A scheme, the scheme of Dual-Servo Motor+airtight gas circuit be Z axis move up and down or the angle of θ axle to rotatablely move be all to be driven by servo electrical machinery system, its principle is, Z axis motor A drives leading screw by rotating, the suction nozzle assembly B of being combined with feed screw nut is moved up and down, suction nozzle assembly B comprises a θ axle electric rotating machine C, this motor C is connected with suction nozzle group front end assemblies, in its outside, there is an inactive cylinder sleeve D, vacuum tracheae E is connected on cylinder sleeve D, O type circle F is all installed at the upper and lower two ends of suction nozzle front end assemblies in cylinder sleeve D, avoid leaking air with cylinder sleeve D inwall close contact.Upper several apertures that bore of suction nozzle seat G of suction nozzle group front end assemblies, to realize the perforation of suction nozzle and outside gas circuit.When θ axle electric rotating machine C rotates, can adjust the anglec of rotation of component suction nozzle.Because suction nozzle seat is only complete upper and lower in cylinder sleeve D inside and rotatablely move, all in strokes, O type circle F all the time with cylinder sleeve D inwall close contact, therefore, there will not be the situation of gas leakage and vacuum passive failure.
In this scheme, each suction nozzle assembly B has independently Z axis and θ axle driven by servomotor, but not the mode of shared cam in option A, thus can more conveniently build many vacuum nozzle system, and can realize a plurality of suction nozzles and adsorb simultaneously and pick up electronic component.
Its workflow is, one or more groups suction nozzle is moved to feeding pallet L top by straight line module, Z axis motor A drives leading screw rotation, the suction nozzle assembly B that promotes combination on feed screw nut is downward, make suction nozzle contact electronic component, by vacuum suction, component pick-up is got up, and keep vacuum suction state, treat that straight line module motion moves to PCB position to be mounted by suction nozzle group, motor A drives suction nozzle downward, electronic component is contacted with the tin cream of application in PCB surface pads, viscosity by tin cream itself overcomes vacuum adsorption force, make element separated with suction nozzle, and be mounted in appointment pad locations.Repeat this process repeatedly, complete the electronical elements surface attachment process to Whole PC B.

C: linear electric motors are in conjunction with the scheme of airtight gas circuit
This scheme roughly the same with B scheme, difference is to have adopted the linear induction motor system that has represented current state-of-the-art technology, replaces originally for realizing servomotor and the leading screw that Z axis moves up and down.Linear electric motors are realized and being moved up and down in conjunction with the total member of suction nozzle, have also comprised the θ axle servomotor of a rotatable suction nozzle angle in the total member of suction nozzle, and its operation principle and B scheme are similar.
Above-mentioned A, B, tri-kinds of schemes of C have contained the technology that the surface-mounting equipments such as current main flow chip mounter adopt.These technology have merits and demerits separately, and the advantage of option A is simple in structure, cheap, but have many unsurmountable inferior positions, are mainly reflected in:
1, no matter be feeding or mount, suction nozzle is all alternation, and execution efficiency is low.
2, suction nozzle interval is larger, and between mounting for twice, the stroke that suction nozzle need to move strengthens, and affects efficiency and improves.
3, adopt spring reset, reset speed goes down with spring tension and slows down, and 0 wearing and tearing of machinery can cause precise decreasing.
4, adopt triangular belt transmission to regulate the suction nozzle anglec of rotation, exist because the rate of tension that belt tightening is inadequate or cause because of wearing and tearing declines, cause the anglec of rotation to lose precision.
Although B scheme has overcome above-mentioned 1, 3, 4 defects, but owing to having adopted Dual-Servo Motor, also has leading screw, the heavier parts such as feed screw nut form, so, mounting head preponderance, therefore the requirement of strength of straight line module is also improved greatly, the direct result causing is like this, mounting head and motion build are large, weight is large, inertia also increases thereupon, need to operation under large movement inertia, need to increase the weight of equipment base to realize even running on the one hand, the speed of Ye Yao controlled motion mechanism reduces inertia on the other hand, the inevitable like this gross efficiency that also restricts equipment.Also have to be exactly because servomotor can not accomplish very little, so if when 2 or above suction nozzle group build, the spacing between each suction nozzle is very large (being greater than the most small-sized servomotor width) still, is about 30-40mm spacing.So just have equally suction nozzle interval larger, between repeatedly mounting, the stroke that suction nozzle need to move increases, and affects the problem that efficiency improves.
C scheme has well solved the defect of A, B scheme, very little (it is reported that diameter 8mm or following linear electric motors industrialization product emerge) that can do due to linear electric motors, so no matter be the total Weight control of mounting head, suction nozzle interval etc. all can effectively be controlled.The unique weak point of linear induction motor system is, linear electric motors and the current price of its driver are very expensive, and unrealized production domesticization completely, the price of single cover linear induction motor system is between ten thousand yuan of 1.5-3, as for setting up the mounting head system of a plurality of suction nozzles, the cost expending is huge, directly causes equipment price high, is difficult to realize industrialization universal.
