Due to the distinctive characteristics of motion of rotation condition mechanism 400 itself, rotation condition mechanism 400 will limit concussion support
300 realize 360 ° of rotation in the same direction, that is to say, that when concussion support 300 revolves, rotation condition mechanism 400 drives shake
Swing support 300 along a direction (such as counterclockwise or clockwise) angle of the rotation less than 360 °, when revolution is to certain position,
Shake angle of the support 300 by rotation in opposite direction less than 360 °.Therefore, when concussion support 300 revolves, rotation is not
Always in the same direction, but periodic variation can be generated.When the direction of rotation generates cyclically-varying, can further mention
The turbulent flow effect of high agent liquid forms more powerful vortex, mixes agent liquid more fully with sample.
Refering to Fig. 4, when rotating cylinder 200 rotates, the notch 521 or magnet on sensor matte 520 into when crossing sensor 510,

If the revolving speed of rotating cylinder 200 is normal, controller 12 will control the rotation time of rotating cylinder 200, determine at what
When stop rotating cylinder 200 rotate, make shake support 300 be parked in designated position, thus be convenient to concussion support 300 on pick and place reaction
Device.In general, sensor 510 is placed on pedestal 100 and designated position corresponding position, when rotating cylinder 200 does not rotate, sensor
Notch 521 or magnet on matte 520 is just corresponding with sensor 510, in this way, when the concussion revolution of support 300 is by specified
When position, a hopping edge signal 530 can be excited.After reaching the concussion time, stop motor 250 and rotate, concussion support 300 will
It is parked in specified location.Specifically, the judgment mode of concussion time can be judged using the number of hopping edge signal 530,
Such as shaking the time is 10s, and the revolving speed of rotating cylinder 200 is 3000rph, then when controller 12 detects the 500th hopping edge signal 530
When, it can control the stopping of motor 250, rotating cylinder 200 stops operating, and concussion support 300 will be parked in designated position.
When controller 12 controls the stopping of motor 250, since motor 250 runs at high speed, there can be inertia, shake support
300 will stop in the place for deviateing designated position, be unfavorable for shaking the positioning of support 300 and the pick-and-place of reactor.It therefore, can be with
After the motor 250 to run at high speed stops, then low rate start motor 250 again, as long as controller 12 detects hopping edge signal
530, indicate that concussion support 300 just past designated position, stops operating, due to horse at this point, controller 12 controls motor 250
It stops operating at low speeds up to 250, it can be to avoid the effect of inertia, so that rotating cylinder 200 is immediately when stopping motor 250
It stops operating, concussion support 300 can stop in specified location, it is ensured that it is accurately positioned.It will be appreciated, of course, that working as motor 250
When can stop under deceleration regime, it also may not need and concussion support 300 positioned by two steps, i.e., it is low in motor 250
In the state of speed operating, when controller 12 detects the last one hopping edge signal 530, stop motor 250, it so also can be quasi-
Determine that support 300 is shaken in position.
