Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

Example 1: as shown in fig. 1-4, a universal elastic sucker mechanism comprises a connecting flange plate 1, two telescopic spring devices 2, a telescopic tightening mechanism 3 and two vacuum suckers 4, wherein the lower ends of the two telescopic spring devices 2 are symmetrically connected to the two sides of the upper part of each vacuum sucker 4 through universal joints 5, the upper ends of the two telescopic spring devices are hinged to the connecting flange plate 1, the upper ends of the telescopic tightening mechanisms 3 are fixedly connected to the middle part of the lower side of the connecting flange plate 1, and the lower ends of the two telescopic tightening mechanisms can be butted to the middle part of the upper side of each vacuum sucker 4.

Preferably, the flexible tight mechanism 3 that tightens includes tight cylinder 9 and arc piece 6, tight cylinder 9 adopts directional telescopic cylinder, cylinder rod tip fixedly connected with

arc piece

6, 6 downside of arc piece is provided with arc wall 7, arc wall 7 can dock the cylinder of the horizontal vacuum tube 8 that sets up in the middle part of the 4 upside of vacuum chuck, horizontal vacuum tube 8 is steel vacuum joint portion, fine rigidity and intensity have, horizontal vacuum tube 8 communicates with vacuum chuck's inner chamber, the cylinder of taking directional pole is flexible, the guidance quality is good, it is reliable and stable to tighten, the cylinder has elasticity, can play the elastic buffer guard action, the cylinder of arc wall laminating horizontal vacuum tube 8, the laminating is stable, the spring of expanding spring device is in the free state, lean on telescopic link and sheathed tube taut cooperation, make the tight state reliable and stable.

Preferably, above-mentioned expanding spring device 2 includes sleeve pipe 10, spring 11 and telescopic link 12, and the upper end of sleeve pipe 10 is sealed, and the lower extreme stretches into telescopic link 12, and spring 11 arranges in the sleeve pipe and both ends lean on respectively and lean on the inside inner of sleeve pipe 10 and the 12 inner of telescopic link, and sleeve pipe 10 is provided with anticreep nut 13, and anticreep nut 13's through-hole internal diameter is less than the 14 external diameters of the evagination ring of telescopic link 12 upper end, can realize elastic expansion, is convenient for realize laminating stability.

Preferably, the middle part in the vacuum chuck 4 is provided with a limiting disc 15, so that the phenomenon that the vacuum air outlet is blocked after soft objects are sucked due to overlarge pressing is avoided.

The use principle is as follows: initial state, the cylinder that tightens stretches out, the sucking disc is in the state of tightening, the manipulator control vacuum chuck removes towards the quilt suction object, when arriving at the quilt suction object top, the cylinder that tightens retracts, the sucking disc is in free state, the manipulator pushes down to the position laminating quilt suction object surface after, the action of control vacuum pump, produce big adsorption affinity, the ascending segment distance of control sucking disc, this moment because both ends spring compression volume is different, the quilt suction object can be preferentially mentioned than the tip of inclining, it is the same until both ends spring expansion volume, the quilt suction object is in the horizontality promptly this moment, the cylinder that tightens is stretched in control, when the arc piece supports the horizontal vacuum tube that leans on the vacuum chuck top, the power of tightening is produced, the stable goods that lifts up of manipulator control sucking disc, place the removal towards the goods.
