As shown in fig. 1 and fig. 2, the stretching device for the irregular-geometry soft object comprises a frame 1, wherein a plurality of pairs of guide rails 10 are arranged on the frame 1, an annular guide rail 13 is arranged at the intersection of the plurality of pairs of guide rails 10, and the annular guide rail 13 is provided with a rotating disc 7; two sliding plates 2 are arranged on each pair of guide rails 10 in a sliding manner, and the two sliding plates 2 are respectively positioned on the outer sides of the annular guide rails 13; a first spring 14 is arranged between each sliding plate 2 and the frame 1; the sliding plate 2 is provided with a clamping mechanism, and a self-locking mechanism is arranged between each sliding plate 2 and the rack 1.
When the soft objects such as leather are stretched, a manipulator is used for placing the leather by taking the rotating disc 7 as the center, then the rotating disc 7 is rotated, and the leather is covered on the plurality of sliding plates 2 at the periphery of the rotating disc 7 under the centrifugal action of the rotating disc 7. Thereafter the robot presses against the leather portion of each slide 2 and expands outwards, and the slides 2 will slide outwards along the corresponding guides 10, causing the leather to be stretched out gradually. When the sliding plate 2 slides to a certain position and the tension of the first spring 14 is large enough, the mechanical hand pushes the leather to slide on the sliding plate 2, the clamping mechanism starts to fix the leather on the sliding plate 2, the self-locking mechanism locks the sliding plate 2 to prevent the leather from rebounding, and the leather is stretched.
As shown in fig. 3, in the stretching device for irregular geometry soft objects of the present invention, the clamping mechanism comprises two mounting slots disposed on the sliding plate 2, each mounting slot is provided with a long gear 26, a short gear 28 engaged with the long gear 26, and a first rack 22 engaged with the long gear 26, the lower end of the first rack 22 is provided with a second spring 25, the second spring 25 is disposed on the lower side of the sliding plate 2 through an L-shaped bracket 21, the upper end of the first rack 22 is provided with a boss 29, and the boss 29 extends out of the sliding plate 2; the axle of the short gear 28 is connected with a pressure plate 8.
