Embodiment
More fully exemplary embodiment is described with reference to the accompanying drawings.Specification indicates identical element with the identical label in accompanying drawing, therefore omission is repeatedly described it.
Fig. 1 is the perspective view of the component retaining head 10 according to exemplary embodiment.
As shown in Figure 1, component retaining head 10 rotates head dummy component retaining head, wherein, swivel head 30 is arranged on head main body 20, to rotate around vertical axes along R direction, multiple main shaft 31 is arranged at regular intervals along the circumferencial direction of swivel head 30, and the ozzle 32 being used as the holding unit of absorbent module is arranged on the bottom of main shaft 31.
Swivel head 30 can rotate along R direction according to the operation of the R servomotor 21 be arranged on head main body 20.In addition, each main shaft 31 can rotate along T direction according to the axle of the operation of the T servomotor 22 be arranged on head main body 20 around main shaft 31.
In addition, head main body 20 is arranged on for making at the main shaft 31a Z servomotor 23 that (that is, axial) declines along the Z direction of ad-hoc location.The mechanism rotated along R direction according to the operation of R servomotor 21 owing to making swivel head 30 and make main shaft 31 be known according to the operation of T servomotor 22 along the mechanism that T direction rotates, so its details will be omitted at this.Now, the mechanism that main shaft 31a is declined according to the operation of Z servomotor 23 will be described in detail.
Fig. 2 is the view for describing for the mechanism making the main shaft 31a of the component retaining head 10 in Fig. 1 decline along the Z direction.The motor shaft being arranged on the Z servomotor 23 on head main body 20 is connected to the screw shaft 24a of ball screw framework 24, and wherein, nut 24b is arranged on screw shaft 24a.In addition, pressure unit 25 is connected to nut 24b.Therefore, pressure unit 25 moves together with nut 24b along the Z direction according to the operation of Z servomotor 23.
Head main body 20 only arranges a pressure unit 25.When main shaft 31 will be made to decline, the main shaft 31(that selection will decline from main shaft 31 by making main shaft 31 carry out relative motion relative to pressure unit 25 will be at the main shaft 31a of ad-hoc location), and make pressure unit 25 decline main shaft 31a is declined.
In other words, according to the present embodiment, swivel head 30 rotates along R direction, to make main shaft 31 carry out relative motion relative to pressure unit 25, thus makes the main shaft 31a that will decline be set to (as shown in Figure 3) under pressure unit 25.Then, exert pressure the main shaft 31a below pressure unit 25 is declined to pressure unit 25.Here, select the main shaft 31a at ad-hoc location and the structure that this main shaft is declined be not limited to above description.Such as, except making main shaft 31 motion select the main shaft 31a that will decline, the main shaft 31a that will decline can also be selected by making pressure unit 25 motion.
As shown in Figure 2, connecting rod 26 is connected to nut 24b(nut 24b and is connected to pressure unit 25), splined nut 28 is connected to connecting rod 26, and Fibre Optical Sensor 40 is arranged on splined nut 28.In addition, splined shaft 27 is set on head main body 20 regularly, and splined nut 28 is slidably disposed on splined shaft 27.In other words, Fibre Optical Sensor 40 and pressure unit 25 are arranged integratedly.Therefore, as shown in Figure 4 A and 4 B shown in FIG., when pressure unit 25 moves along the Z direction according to the operation of Z servomotor 23, Fibre Optical Sensor 40 correspondingly moves along the Z direction.
Fig. 4 A is main shaft 31a in Fig. 2 view when being in initial position, and Fig. 4 B is view when making the main shaft 31a in Fig. 2 be in decline state by pressure unit 25.Here, main shaft 31 1 was elastically supported towards initial position straight through the comprising two helical spring elastic devices 33 of Fig. 2.
Meanwhile, Fibre Optical Sensor 40 comprises luminescence unit, light receiving unit and optical fiber, and due to Fibre Optical Sensor 40 be known, therefore its details is no longer described here.
In the present embodiment, as shown in Figure 2, Fibre Optical Sensor 40 is arranged along relative to the acclivitous direction of ozzle 32.In addition, the luminescence unit of Fibre Optical Sensor 40 is along downward-sloping direction towards the reflecting surface 32a utilizing emitted light P of the external top surface of the ozzle 32 shown in Fig. 5.The light P launched reflects on reflecting surface 32a, and receives the light of reflection by the light receiving unit of Fibre Optical Sensor 40.
Here, ozzle 32 is arranged on the bottom of main shaft 31.Helical spring 34 is arranged between main shaft 31 and ozzle 32 as elastic component.Therefore, if ozzle 32 falls while main shaft 31 declines, so helical spring 34 is compressed, and therefore ozzle 32 changes in the vertical direction relative to the relative position of main shaft 31.In detail, ozzle 32 carries out relative motion towards the bottom of main shaft 31.Here, ozzle 32 " under fall within ... on " statement, it is roughly meant to apply power from the bottom of ozzle 32, and during being included in assembly pick-up operation, while ozzle 32 moves downward ozzle 32 bottom under fall within situation on the top surface of assembly, and during component mounting operation, under being adsorbed onto the assembly of the bottom of ozzle 32, fall within the situation on the top surface of substrate.
Meanwhile, under the initial condition that ozzle 32 does not fall, focus on reflecting surface 32a from the light P scioptics 40a of the luminescence unit radiation of Fibre Optical Sensor 40.Therefore, when falling to making ozzle 32 change in the vertical direction relative to the position of main shaft 31 along with ozzle 32, the amount of the reverberation reflected by reflecting surface 32a is reduced, and the light quantity that therefore light receiving unit of Fibre Optical Sensor 40 receives reduces.In the present embodiment, the sensor unit 40b being decreased through Fibre Optical Sensor 40 of the light quantity of reception detects.
When the light quantity received reduces scheduled volume, sensor unit 40b determines that ozzle 32 falls, and produces whereabouts detection signal.In the present embodiment, when condition below meeting, determine that the light quantity received reduces scheduled volume, thus produce whereabouts detection signal.
In other words, as shown in Figure 6, the light quantity of reception is unstable and changes according to the time, and when ozzle 32 falls, the light quantity of reception reduces rapidly.Therefore, in the present embodiment, sensor unit 40b measures the light quantity f (t) of the reverberation of reception constantly.And when the light quantity f (t) received is less than or equal to first threshold, and when the absolute value of rate of change df (the t)/dt of the light quantity f (t) received is equal to or greater than Second Threshold, sensor unit 40b produces whereabouts detection signal.Therefore, the whereabouts detection signal of the generation mistake caused due to the light quantity of the reception of instability is prevented.Here, first threshold and Second Threshold are suitably determined according to the actual unstable degree of the light quantity received by designer.In the present embodiment, the light quantity of reception by performing satin face process (satin process) and stably keeping on the reflecting surface 32a of ozzle 32.
In addition, in the present embodiment, downward-sloping 45 ° are set to from the direction of the light P of the luminescence unit radiation of Fibre Optical Sensor 40.Because the direction of light P is downward, so Fibre Optical Sensor 40 can be arranged on ozzle 32.Therefore, Fibre Optical Sensor 40 can not cause adverse influence for the falling operation of ozzle 32.
According to the surface stick-mounting machine comprising the component retaining head 10 with said structure, by being arranged on the ozzle 32 of the bottom of main shaft 31 from assembly feeding unit picking up assembly, assembly is sent to printed circuit board (PCB), then assembly is arranged on the ad-hoc location of printed circuit board (PCB).
Pick up and installation component time, as above with reference to described by Fig. 2, the top of main shaft 31a is pressed by pressure unit 25, declines along the Z direction to make main shaft 31a.Then, when the ozzle 32 of the end at main shaft 31a falls, helical spring 34 is compressed (as mentioned above) and ozzle 32 changes in the vertical direction relative to the relative position of main shaft 31a, and therefore, the light quantity that the light receiving unit of Fibre Optical Sensor 40 receives reduces.Then, the sensor unit 40b of Fibre Optical Sensor 40 produces whereabouts detection signal.Whereabouts detection signal is sent to the control unit 50 shown in Fig. 2.According to the whereabouts detection signal received, the Z servomotor 23 that control unit 50 makes to be used as the decline unit that pressure unit 25 is declined stops.Therefore, the descending stroke of ozzle 32 is properly controlled, thus ozzle 32 is accurately fallen.
Fig. 7 is according to exemplary embodiment, for being described through the view of the example using control unit 50 control Z servomotor 23.Figure 7 illustrates, according to the operation of Z servomotor 23, according to the time, the descending stroke of ozzle 32 and decrease speed.The design load of descending stroke is 8mm.
As shown in Figure 7, control unit 50 control Z servomotor 23, makes decrease speed higher between initial decrement phase, when stroke is 3mm(first height and position) time, decrease speed reduces gradually, then when stroke is 6.7mm(second height and position) time, decrease speed is at the uniform velocity.Then, along with ozzle 32 falls, according to the whereabouts detection signal received from Fibre Optical Sensor 40, control unit 50 makes Z servomotor 23 stop.
Figure 7 illustrates, when descending stroke be 8mm(namely, make the design load that ozzle 32 falls always) time, Three models when descending stroke (that is, 9mm) is greater than design load and when descending stroke (that is, 7mm) is less than design load.In any pattern, descending stroke is properly controlled, and therefore ozzle 32 accurately falls.
In addition, in one or more embodiment, the sensor unit 40b of Fibre Optical Sensor 40 is set up with control unit 50 independent, but the function of sensor unit 40b performs by control unit 50.In addition, according to one or more embodiment, Fibre Optical Sensor 40 uses noncontacting proximity sensor as the detecting unit of the whereabouts for detecting ozzle 32, but can use another noncontacting proximity sensor (such as, magnetic sensor).
In addition, component retaining head 10 can be another type instead of rotate head dummy.
As mentioned above, according to exemplary embodiment, a pressure unit 25, for multiple main shaft 31, carries out relative motion to select the main shaft 31a that will decline relative to pressure unit 25 by making multiple main shaft 31, then make pressure unit 25 decline, thus the main shaft 31a of selection is declined.Then, the Fibre Optical Sensor 40 arranged integratedly with pressure unit 25 detects the whereabouts of the ozzle 32 of the bottom being arranged on main shaft 31a, and therefore Fibre Optical Sensor (noncontacting proximity sensor) 40 can detect the whereabouts of each ozzle 32.
As mentioned above, according to exemplary embodiment, component retaining head comprises the multiple holding units for keeping assembly, but the detecting unit that is dropped through of each holding unit detects.Therefore, the descending stroke of holding unit suitably can control and need not increase the size of component retaining head and the cost increased for the manufacture of component retaining head.
Although described one or more embodiment with reference to the accompanying drawings, but those of ordinary skill in the art will be appreciated that, when not departing from the spirit and scope of the present invention's design be defined by the claims, in form and details, various change can be made to it.
