In addition, the present invention relates to, especially relate to improvement the laser beam shape of test portion fluid irradiation applicable to industrial robot, the corpuscular counter that utilizes light scattering characteristic that the population in the gas is measured.
Background technology
This robotlike, have a kind of in absolute clean room such as semiconductor wafer or liquid crystal panel are placed on the robot that moves to other devices on hand from box.When handling these semiconductor wafers and liquid crystal panel, the number of particles in the clean room has very big influence to qualification rate, so several method inspection is arranged.
Such as, the assigned position of staff in clean room is provided with corpuscular counter and makes regular check on sometimes.In addition, corpuscular counter also being installed sometimes on the manufacturing installation of sputter or etching etc. makes regular check on.Or utilize testing fixture that the particle inspection is carried out on the surface of semiconductor wafer and liquid crystal panel.
In addition, as existing this type of corpuscular counter 100 as shown in figure 10, comprise the light source 102 of launching laser 101, with laser 101 optically focused to the collector lens 103 of test portion fluid 104, make flow passage device 105 that test portion fluid 104 flows, scattered light 106 that the particle in the test portion fluid 104 (grit) is produced gives the sensitive lens 107 of optically focused, the scattered light behind the optically focused 106 is carried out the light-sensitive element 108 of opto-electronic conversion.And the impulse magnitude of the electric output power that obtains from light-sensitive element 108 and the particle diameter of suspended particles have dependency relation, so can try to achieve particle diameter from the impulse magnitude of electric output power.In addition, particle by the time produce pulse, so can obtain population from the number of times of pulse.
Owing to making the energy density of laser 101 high more good more, so collector lens 103 is arranged to laser 101 optically focused are become very little point-like in order to detect scattered light 106 accurately.And test portion fluid 104 is by the inspection area 109 of point-like.The mobile of test portion fluid 104 is to utilize the suction pump in downstream to carry out.
On the other hand, predict dirty occasion when this device 100 is monitored the dirty degree in the clean room and be used as the occasion of the device of reporting to the police, wish to monitor a large amount of test portion fluids 104 at short notice, realize the prediction of the dirty degree that correctness is high, to give the alarm in early days.

And, when a plurality of arms are rotatably connected mutually, the revolving force of rotary driving source is transmitted robot with actions such as stretching, be loaded in such as the workpiece that makes large-scale liquid-crystalline glasses etc. the carrying of moving between the flow path device of box and coating device etc. with robot on.
This type of carrying comprises with robot 501 as shown in figure 15: with the joint portion on the pedestal 509 502 be rotatable the 1st arm 505 in center, the 2nd arm 506 that rotatably is connected with the joint portion 503 of the front of the 1st arm 505, the hand 510 that rotatably is connected with the joint portion 504 of the leading section of the 2nd arm 506.In each joint portion 502~504, be built-in with belt pulley, and connect by synchronous belt respectively between the joint portion 502,503 and between the joint portion 503,504, be arranged to hand 510 all the time in the face of certain direction and on straight line, move.Hand 510 has 2~3 hand fork 510a usually.
But along with the maximization of liquid-crystalline glasses in recent years, the adversary has also had the requirement of rigidity.If hand 510 rigidity deficiencies, even or the much of that but preponderance of rigidity, then carrying descends with the resonant frequency of robot 501 and can't high speed motion.
In addition, it is said that be exactly the access time of workpiece 508 2/3 of the actuation time when using carrying with robot 501.Therefore, in order to shorten the beat of operation, need make the discrepancy high speed of workpiece 508.In addition, also enlarge with the maximization of workpiece 508 even consider the stroke of discrepancy, the high speed of the part of coming in and going out also is very important with being directly proportional.
In order to realize the discrepancy high speed of workpiece 508, need to suppress the weight of hand 510 and improve rigidity.Therefore, carried out 3 changes of hand fork, in carbon fiber, contain resin pickup to form trial such as hand fork.In addition, hand fork was to be that square rustless material forms by the cross section in the past, but was to be main flow with the hollow shape that can obtain high rigidity now.That is, hand fork is to be dimetric tubing from cardinal extremity to front end with the cross section of identical thickness as shown in figure 14.
