Detailed description of the invention
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
As Figure 1-5, including having the cylinder body 1 of plunger shaft 2, be provided with in plunger shaft 2 can in plunger shaft 2 reciprocating shaft
To moving and plunger shaft 2 can be separated into the first chamber 3 and piston 5 of the second chamber 4 vertically, piston 5 one end has position
Piston rod 5a in the second chamber 4, piston rod 5a extend to outside cylinder body 1 and piston rod 5a seals with cylinder body 1 and is slidably connected, and live
Stopper rod 5a outer end is provided with vacuum cup 5b, and piston 5 has axially extended suction hole 6, and suction hole 6 one end is with the first chamber 3 even
Logical, the other end extends to piston rod 5a outer end and connects with vacuum cup 5b, and cylinder body 1 is provided with and is connected with the second chamber 4
Aspirating hole 7, is additionally provided with at least one on piston 5 and connects the first chamber 3 and the second chamber 4 and when aspirating hole 7 is to the second chamber 4
The first chamber 3 can be made when bleeding and the second chamber 4 produces draught head so that piston 5 drives piston rod 5a moved axially forward
Gas port 10, is provided with the resetting-mechanism 8 that piston 5 can be made to reset between cylinder body 1 and piston 5.
In the present embodiment, described aspirating hole 7 is connected with vacuum generator, by vacuum generator to cylinder body 1
One chamber 3 is bled, and owing to the cross-sectional area of aspirating hole 7 is more than the cross-sectional area sum of each gas port 10, therefore makes
After must bleeding, the air pressure in the first chamber 3 is less than the air pressure in the second chamber 4, so that the first chamber 3 and chamber 4 two
Air pressure balance in chamber, piston side shifting outward, during until the vacuum cup 5b on piston contacts with plate, plate and adhesive
Portion 5d forms sealing and completes adsorption process；Subsequently, vacuum generator continues to bleed, owing to now plate is formed with vacuum cup 5b
Sealing, now the first chamber 3 is identical with the second chamber 4 negative pressure, owing to the sectional area of corresponding second chamber 4 of piston is big, and corresponding the
The sectional area of one chamber 3 is little, so that piston component 5 bounces back, thus realizes suction process, and after suction completes, vacuum occurs
Device quits work, and takes off material, and now the second cavity internal gas pressure restores balance, and completes whole reclaiming process, repeats above step
Repeatedly suction can be carried out.In the process, single pumping process is carried out by vacuum generator, it is possible to realize piston component axial
Mobile, it is not necessary to be inflated, two processes of exitting complete, and the retraction process of piston 5 betides vacuum cup and connects with plate
After touching and forming sealing, compare tradition and driven the mode of operation of piston rod by inflation, venting, need the axial shifting to piston rod
Dynamic distance carries out precise positioning, otherwise can move meeting not in place because of piston rod and make vacuum cup not in place with plate absorption,
Cause this suction procedure failure, follow-up work process impacted, or move down too much can to plate formed compressing so that
Panel surface deforms, automatic retracted after being adsorbed by this device, piston and plate, it is not necessary to the axial displacement to piston component is carried out
Location, vacuum cup has certain elasticity simultaneously, sheet material will not be formed compressing and make sheet deformation, ensure that suction simultaneously
The success of material process, structure design is more reasonable, meets production needs.
Specifically, resetting-mechanism 8 includes one end effect of the spring 8a, spring 8a that are arranged between cylinder body 1 and piston 5
On cylinder body 1, the other end acts on piston 5, is supported piston 5 by spring, and the gravity for dummy piston 5 is made
With.
Between piston 5 and cylinder body 1, it is provided with the stroke limit structure 9 that can limit piston 5 shift motion, the trip simultaneously
Position limiting structure 9 includes the first limited step 9a being arranged in the second chamber 4 and the second limited step being arranged on piston 5
9b, and the first limited step 9a and the second limited step 9b can mutually support after piston 5 drives piston rod 5a moved axially forward
Lean on.
Further, cylinder body 1 includes tubular cylinder barrel 1a and is fixed on the rear end cap 1b of cylinder barrel 1a rear end, rear end cap
1b is provided with cavity 1c and ingredient that this cavity 1c is the first chamber 3, and gas port 10 is connected with cavity 1c all the time, air-breathing
Hole 6 is connected with cavity 1c all the time.The cross-sectional area of aspirating hole 7 is more than the cross-sectional area sum of each gas port 10.Vacuum
Sucker 5b includes tubular socket part 5c and is arranged on outside the adhesive portion 5d, socket part 5c and piston rod 5a of 5c front end, socket part
End socket-connects, and vacuum cup 5b is made up of elastomeric material, can effectively alleviate the piston rod 5a pressure to sheet material by elastomeric material
Compel, make sheet material to deform.
The specific works process of this device is as follows:
First chamber 3 is bled by aspirating hole 3 by vacuum generator, owing to gas port 10 diameter is less, because of
Air pressure in this first chamber 3 is less than the air pressure in the second chamber 4, and therefore piston 5 side shifting outward, when vacuum cup 7 and plate
After material contacts and adsorbs with plate, the second chamber 4 forms confined space, and vacuum absorber starts to extract the gas in the second chamber 4
Body the air pressure in making the second cavity 4 reduce, so that piston 5 retraction drop plate under atmospheric pressure and together promote,
Reaching specific bit to postpone, vacuum generator quits work so that first chamber the 3, second chamber 4, suction hole 6 internal gas pressure are the most extensive
Completing feeding after normal atmosphere again, the suction process of single terminates.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the most more employ cylinder body 1, cylinder barrel 1a, rear end cap 1b, cavity 1c, plunger shaft the 2, first chamber 3,
