According to the actual needs of production, open-close type pick-and-place manipulator is installed on the motion platform shown in Fig. 2 or other mechanical movement means usually, when this pick-and-place manipulator moves to above material grasping position by these motion platforms or mechanical movement means, this manipulator implements material grasping automatically, when the pick-and-place manipulator after material grasping is moved to above discharge position by these motion platforms or mechanical movement means, this manipulator implements blowing automatically.Its specific works process is as follows:
When this pick-and-place manipulator arrives above material grasping position, the x-axis motor 14 and the y-axis motor 16 that obtain the x-y motion platform module of the pick-and-place manipulator of the information of putting in place almost start simultaneously, x-axis motor 14 drives the first Timing Belt wheels 15 and the second Timing Belt wheels 19 to be synchronized with the movement, drive the second component suction nozzle 27 and the 4th component suction nozzle 26, in x direction respectively simultaneously to the first component suction nozzle 29 and the 3rd component suction nozzle 28 near or away from, to make the suction nozzle on corresponding suction nozzle module and to be grabbed material consistent in the spacing in x direction; Almost meanwhile, y-axis motor 16 drives screw mandrel 31, by the feed screw nut 21 coordinated with screw mandrel 31, brought into motion arm 23 in y direction near or away from riser 17, even if the 3rd component suction nozzle 28 be arranged on transfer arm 23 and the 4th component suction nozzle 26 be arranged on the first component suction nozzle 29 on riser 17 and the 3rd component suction nozzle 28 remains close to or away from, to make the suction nozzle on corresponding suction nozzle module and to be grabbed material consistent in the spacing in y direction.
When each suction nozzle interval on x-y platform module and consistent by material grasping spacing on material grasping position (charging tray), z-axis motor 4 starts immediately, by eccentric shaft 13, roller 12, roller groove 11 and the slide block 9 connected firmly mutually with x-y platform module, x-y platform module is driven to move downward, make each suction nozzle and grabbed material to keep certain distance, each cylinder (i.e. the first ~ four each cylinder) afterwards on x-y platform module starts simultaneously, promote each suction nozzle downwards near being grabbed material, almost meanwhile, vacuum air-channel on each suction nozzle is opened, crawled material holds by suction nozzle respectively.The z-axis motor obtaining the crawled information of material starts immediately, drive x-y platform module to rise to put in place, almost meanwhile, relative motion platform also starts immediately, this pick-and-place manipulator of material is had to move to above discharge position crawl, now, x-axis motor 14 on x-y platform module and y-axis motor 16 start, according to pre-set program, according to above-mentioned start-up routine, when to make on each suction nozzle consistent by the spacing of the spacing with discharge position of grabbing material, it is downward that z-axis motor 4 starts promotion x-y platform module immediately, make each suction nozzle grabbed material and discharge position keeps certain distance, each cylinder (i.e. the first ~ four each cylinder) afterwards on x-y platform module starts and closes vacuum air-channel 43 downwards simultaneously, the material on each suction nozzle is made precisely to be placed into discharge position.Afterwards, z-axis motor starts again, drives x-y platform module to rise and puts in place, prepare second time and remove pick-and-place material.So repeatedly, just can be very fast by the discharge position of the material pick-and-place of a kind of spacing of material grasping position to another kind of spacing.
