In RAM10c, be provided with various working storage sum counters etc., as the service area in the electronic unit installation action.And, the result of RAM10c storage CPU10a.
Then, control part 10 has the function as parts installation and control unit, the control program that this parts installation and control unit puts rules into practice, the action of each one by control device, the posture from the electronic unit D of parts supply unit 4 that is provided in that suction nozzle 6a on the load head 6 kept is adjusted, loaded and install at the assigned position of the parts installation site of the regulation of transporting the path by the substrate substrate supported P of institute.
In addition, control part 10 detects the detection signal of substrate P according to substrate detecting sensor 3a, discerns the position of substrate P, and makes it to stop at the control of the parts installation site of regulation.
And control part 10 is not blocked the laser that arrives light accepting part 5b by electronic unit D according to laser recognition unit 5 (light accepting part 5b) is detected, discerns the control of the posture of the electronic unit D that is kept by suction nozzle 6a.
And control part 10 makes the control of mouth mobile unit 6b or a mobile unit 7 actions according to the posture of the electronic unit D that is kept by suction nozzle 6a that is discerned, so that adjust the posture that is loaded in the electronic unit D on the substrate P.
Particularly, control part 10 has the function as the part of parts detecting unit, this parts detecting unit is after suction nozzle 6a keeps electronic unit D, in a plurality of timings during load head 6 with the suction nozzle 6a that keeps electronic unit D moves with respect to substrate P, make laser recognition unit 5 action, so that the posture by the electronic unit D that leading section kept of this suction nozzle 6a is detected.
For example, as soon the timing after suction nozzle 6a will keep from the electronic unit D of parts supply unit 4 of the control part 10 of parts detecting unit, and the load head 6 with the suction nozzle 6a that has kept electronic unit D moves with respect to substrate P, promptly, in the timing before will being loaded in this electronic unit D on the substrate P, 5 pairs of postures by the electronic unit D that leading section kept of suction nozzle 6a of laser recognition unit are detected, obtain the coordinate of the electronic unit D relevant and the control of angle with this posture.
And, control part 10 has the function that obtains the unit as the parts comparing data, this parts comparing data obtains the unit comparing as the posture of the electronic unit D in control part 10 detected a plurality of timings of parts detecting unit, and obtains the different relevant parts comparing datas of posture with electronic unit D.
For example, the control part 10 of obtaining the unit as the parts comparing data carries out and suction nozzle 6 the electronic unit D from parts supply unit 4 is kept after the relevant X-direction of posture of electronic unit D in soon the timing, Y direction, numerical value (the X1 of the coordinate of θ direction and angle, Y1, θ 1) be about to be loaded on the substrate P before timing in the relevant X-direction of posture of electronic unit D, Y direction, numerical value (the X2 of the coordinate of θ direction and angle, Y2, θ 2) compare, obtain parts difference data (Δ X as this difference, Δ Y, Δ θ)=(X2-X1, Y2-Y1, θ 2-θ 1) control.
Here, the coordinate of electronic unit D after will keeping from the electronic unit D of parts supply unit 4 as suction nozzle 6a in soon the timing and the numerical value (X1 of angle, Y1, θ 1), with be about to be loaded on the substrate P before timing in the coordinate of electronic unit D and the numerical value (X2 of angle, Y2, θ 2) parts difference data (the Δ X of difference, Δ Y, Δ θ) is illustrated in the process that load head 6 with the suction nozzle 6a that will keep from the electronic unit D of parts supply unit 4 moves with respect to substrate P, the posture of the electronic unit D that is kept by suction nozzle 6a changes, and the side-play amount of skew takes place in the position of electronic unit D.
Owing to have load head 6 fast moving of suction nozzle 6a, so that shorten electronic unit D is loaded in loading pitch time on the substrate P, thereby in the load head in stopping 6 moment of moving or the load head 6 in moving moment of stopping etc., often produce big inertia force.Because the effect of this inertia force often makes the posture of the electronic unit D that is kept by suction nozzle 6a change, and the position of electronic unit D is offset.
And, control part 10 has the function as judging unit, this judging unit compares the pre-determined reference value of being stored in obtained parts difference data of the control part 10 of obtaining the unit as the parts difference data and the ROM10b, and whether the decision means difference data is more than or equal to fiducial value.
Here, in the process that the load head 6 with suction nozzle 6a that the electronic unit D from parts supply unit 4 is kept moves with respect to substrate P, under the little situation of the degree of the posture of the electronic unit D that is kept by suction nozzle 6a or position change, be difficult to take place and the relevant fault of the loading of electronic unit D on substrate P, and under the big situation of the degree of the posture of electronic unit D or position change, often take place and the relevant fault of the loading of electronic unit D on substrate P.
Therefore, carry out the comparison of predetermined reference value and parts difference data, thereby judge the degree of the possibility that the fault relevant with the loading of electronic unit D on substrate P takes place.For example, if carry out the parts difference data more than or equal to fiducial value then the judgement of breaking down easily, if carry out the parts difference data smaller or equal to fiducial value then the judgement that is difficult to break down.
And, control part 10 has the function as stop control unit, this stop control unit is judged as under the situation of parts difference data more than or equal to fiducial value at the control part 10 as judging unit, make each one of device temporarily stop action, the electronic unit D that is kept by suction nozzle 6a is loaded in action on the substrate P so that stop.
And, control part 10 has the function as the part of notification unit, this notification unit is judged as under the situation of parts comparing data more than or equal to fiducial value at the control part 10 as judging unit, display part 12 is shown be used to the message of notifying expression that the unusual meaning is arranged by the electronic unit D that suction nozzle 6a kept etc.
And, control part 10 has the function as storage control unit, this storage control unit is judged as under the situation of parts difference data more than or equal to fiducial value at the control part 10 as judging unit, makes memory cell 13 storages follow and be judged as more than or equal to the corresponding relevant attached data of electronic unit D of the parts difference data of fiducial value.
