It refers to shown in Fig. 9, when the suction means for being adsorbed with plate 4 needs to discharge plate 4, it is only necessary to close vacuum pump
(not shown), gas can be back to via through hole 214 in chamber 321, allow pressure in gas passage 211 and chamber 321
Force value tends to balance, and air permeable disc 323 is dropped down onto under the gravity of itself above open-work 324, and bead 322 then drops down onto air permeable disc
323 tops, prevent bead 322 from blocking open-work 324, at this point, air can be flowed into via multiple air holes 3231 and open-work 324
In the stomata 311 of flexible sucker 31, the atmospheric pressure value in flexible sucker 31 is adjusted, so as to which quick release is attracted to flexible sucker 31
Plate 4 on bottom.
The sucker group structure-improved of the suction means of the utility model is by being arranged in chamber 321 and positioned at bead 322
The air permeable disc 323 of bottom part down, when vacuum pump offer positive pressure, air permeable disc 323 covers in open-work 324, and bead 322 falls ventilative
On disk 323, so as to which bead 322 be avoided to block open-work 324, gas is allowed to be stretched via the inflow of multiple air holes 3231 of air permeable disc 323
In contracting sucker 31, the atmospheric pressure value in flexible sucker 31 is adjusted, so as to fulfill the plate 4 that quick release is adsorbed by flexible sucker 31,
The work efficiency of suction means is improved, certainly, according to actual needs, those of ordinary skill in the art can also be in air permeable disc
Multiple air holes 3231 of different pore size on 323 are set, gas is conveniently adjusted and flows into the throughput size stretched in sucker 31.
More than content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
Limitation to the utility model.
