Embodiment one
The present embodiment proposes a kind of vacuum chuck, is used for robot.
Incorporated by reference to referring to Fig. 1 and Fig. 2, the vacuum chuck includes:
Pedestal 100, including the leading flank 110 towards external adsorption plane, the leading flank 110 is equipped with and vacuumizes hole 120.Its
In, pedestal 100 generallys use plastic material or metal material.So as to structural strength with higher, so that vacuum
The structure of sucker is able to maintain stabilization.Vacuumize the through hole that hole 120 is usually arranged as perforation front and back sides.But vacuumize hole
120 structures that can also be entered using leading flank, and be drawn by all sides.
Enclosure wall portion 200 is connect and in standing shape facing forward, the enclosure wall portion 200 with the leading flank 110 of the pedestal 100
It is arranged in around the hole 120 that vacuumizes, and forms a cavity (not marking) with opening with the pedestal 100, it is described
Cavity vacuumizes hole 120 described in and the opening is connected to external.Wherein, the opening of cavity for external adsorption plane phase
Right, when opening is supported with external adsorption plane blocks, then only residue vacuumizes hole 120 and is in communication with the outside cavity.
The enclosure wall portion 200 includes the multilayer spongy layer 210 of stacking, and is set between adjacent two spongy layer 210
Hard member 220.Wherein, spongy layer 210 has certain flexibility, can be respectively to compression.And hard member 220 and spongy layer
210 compare, and quality is harder, and the rigidity in sucker grasp force direction is smaller, and have biggish lateral rigidity, it is not easy to generate side
To deformation.Such as hard member 220 can use thin metal material, such as sheet metal component or the ABS plastic production of 1mm thickness, from
And structural strength with higher.
Vacuum chuck provided by the present embodiment is supported external adsorption plane by that will be open first, is then led at work
The external air pump that vacuumizes is crossed to be vacuumized.Then, since inside cavity air pressure reduces, so that in enclosure wall portion 200
Spongy layer 210 is under pressure, and generates front-rear direction compressive deformation.Simultaneously as the support force that hard member 220 provides, described
It enclosure wall portion 200 will not be from the inside contraction distortion in side.It avoids as shown in figure 3, working as what enclosure wall portion 200 was stretched out forward and backward
Distance is remoter, then the deflection of side to contract is bigger, and causes due to lateral deformation, and the sealing effect generated and crawl
The problem of power declines.
Therefore, vacuum chuck provided by the present embodiment, by setting enclosure wall portion in multilayer spongy layer 210 centre,
Increase hard member 220, to reach increase lateral stability.In turn, can be bigger using thickness in the front-back direction, and wall thickness
Lesser sponge then can obtain bigger effective active area in the case where suction tool overall dimension is constant, to improve
Vacuum sponge inhales the performance of tool.
Further, in the present embodiment, the hard member 220 is ABS plastic plate.Wherein, hard member 220 uses ABS
Plastics, thus structural strength with higher, and there is lighter weight.Further, setting hard member 220 is engraved in middle part
Empty hollow plate shape, it is mutually stacked layer by layer so as to be formed with spongy layer 210, so that easily fabricated be also readily able to distinguish from appearance
Know.Certainly, in other embodiments, 220 are also possible to be hidden in spongy layer 210, i.e., observe in the appearance of vacuum chuck
Less than hard member 220.For example, the hard member 220 can also use metal plate.Or the hard member 220 is used and is embedded in
Round in spongy layer 210.I.e. hard member 220 is round or polygon circle body in cross section.
Further, in the present embodiment, pass through two-sided glue sticking between the hard member 220 and spongy layer 210.Pass through
Sticking double faced adhesive tape can then play fixed effect.And it is easy to cause spongy layer 210 to harden compared to using glue bonding,
And the shrinkage of thickness direction is caused to reduce.The present embodiment uses the scheme of two-sided glue connection, and spongy layer 210 can be guaranteed in thickness
Spend the flexibility on direction.
Further, in the present embodiment, the quantity of the spongy layer 210 is three layers, in the front-back direction with a thickness of 10 ± 2
Millimeter.Wherein, the quantity of spongy layer 210 is three layers, correspondingly, 220 quantity of hard member is two layers.In the present embodiment, using three
Layer spongy layer 210, and control thickness at 10 millimeters or so so as to relatively mild thickness, and obtains appropriate
Effective active area so that vacuum chuck better performances.
Certainly, in other embodiments, the number of plies of spongy layer 210 can also use two layers, four layers or five layers etc.,
This is not construed as limiting.
Further, in the present embodiment, the enclosure wall portion 200 is connected to the edge of 100 leading flank 110 of pedestal.
In the present embodiment, the edge of the enclosure wall portion 200 and pedestal 100 is aligned, so that the globality of the outer surface of vacuum chuck
It is higher, it is easier to assembly and use.
Further, in the present embodiment, the enclosure wall portion 200 is rectangular.Certainly, in other embodiments, enclosure wall
Portion 200 can also be round, triangle or other polygons etc..
The utility model also proposes a kind of robot, which includes vacuum chuck, the specific structure of the vacuum chuck
Referring to above-described embodiment, since robot uses whole technical solutions of above-mentioned all embodiments, at least have upper
All beneficial effects brought by the technical solution of embodiment are stated, this is no longer going to repeat them.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes
It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
