[0002] At present, the main methods of automatic fabric grabbing and transfer are robot grabbing, negative pressure adsorption, electrostatic adsorption and non-contact suction cup adsorption. The process of automatic fabric grabbing and transfer can be divided into the process of finding objects, clamping objects, lifting objects, moving objects and releasing objects. The needle suction cup is a commonly used adsorption tool. Its principle is mainly to form negative pressure inside the suction cup so that it can adsorb the surface of the adsorbed object to achieve the purpose of adsorption. Its advantages are strong adsorption force, good flexibility and wide application range. Therefore, it is widely used in various industrial automation equipment.

[0029] As Figures 1 - 5As shown in the figure, an embodiment of the present utility model provides a fabric raw material grasping device for fabric processing, including: a mounting frame 1 and a moving frame 2. The upper end of the moving frame 2 is slidably connected to the moving frame 2. A cylinder 4 is fixedly penetrated through the upper end of the moving frame 2. The telescopic end of the cylinder 4 is fixedly connected to a needle-type suction cup 7. A positioning mechanism 5 is arranged below the needle-type suction cup 7. The positioning mechanism 5 includes a lifting plate 50 and an L-shaped plate 52. Limiting grooves 55 are opened at positions near both sides of the upper end of the lifting plate 50. Two fixed plates 51 are respectively fixed inside two groups of limiting grooves 55 at the upper end of the lifting plate 50. Springs 54 are fixedly connected to one side of the two fixed plates 51. The inner walls of the two L-shaped plates 52 are respectively fixedly connected to the two springs 54. Vibration motors 53 are fixedly connected to the inner walls of the two L-shaped plates 52. The lower ends of the two L-shaped plates 52 are respectively located inside the two groups of limiting grooves 55. Four telescopic rods 57 are fixedly connected to the lower end of the lifting plate 50. The other ends of the four telescopic rods 57 are all fixed to the inner bottom surface of the mounting frame 1. A bottom plate 511 is arranged at the lower end of the lifting plate 50. One end of the bottom plate 511 is fixedly connected to one end inside the mounting frame 1. Two sliding seats 58 are slidably connected to positions near both sides of the lower end of the bottom plate 511. A finisher 56 is rotatably connected to the upper end of each of the two sliding seats 58. The finisher 56 is composed of two flexible rollers. A limiting rod is arranged on one side of the finisher 56. The limiting rod is fixedly connected to the upper end of the sliding seat 58. A rotating connecting piece 59 is rotatably connected to the lower end of the bottom plate 511. Connecting rods 510 are rotatably connected to positions near both ends of the lower end of the rotating connecting piece 59. The other ends of the two connecting rods 510 are respectively rotatably connected to the bottoms of the two sliding seats 58. An electric telescopic cylinder 512 is fixedly installed at a position near one side of the lower end of the bottom plate 511. The telescopic end of the electric telescopic cylinder 512 is fixedly installed with the lower end of one of the sliding seats 58. Place the stacked fabric on the lifting plate 50. By starting the electric telescopic rods 57, the telescopic end of the electric telescopic cylinder 512 shortens to drive one of the sliding seats 58 to move closer to the middle position of the bottom plate 511, further driving the two connecting rods 510 and the rotating connecting piece 59 to rotate in cooperation, so that the other sliding seat 58 also moves synchronously. When the edge of the sliding seat 58 reaches the edge of the lifting plate 50, due to the limiting effect of the lifting plate 50, the sliding seat 58 stops moving. At this time, the four finishers 56 at the upper end are attached to the four corners of the fabric, playing a role in sorting and positioning the fabric. Further, by starting the two vibration motors 53, the vibration motors 53 drive the L-shaped plates to move back and forth along the limiting grooves 55, playing a role in sorting and strengthening the fabric attached to one side of the L-shaped plate 52. The springs 54 play a role in maintaining the stability of the L-shaped plate 52. Therefore, the positioning mechanism 5 can play a very good sorting role for the stacked fabric. By simultaneously starting the four telescopic rods 57, the four telescopic rods 57 extend to drive the lifting plate 50 to move upward, separating from the bottom plate 511, and transporting the fabric to be transported to a suitable height for the needle-type suction cup 7 to suck the fabric.

[0030] AsFigure 1 and Figure 2 As shown, a processing table 3 is fixedly installed on the inner bottom surface of the installation frame 1, and the other end of the bottom plate 511 is fixed to one side of the processing table 3. A servo motor 6 is fixedly installed on the upper end of the mobile frame 2, and a gear 9 is fixedly installed on the output end of the servo motor 6. A rack 10 is fixedly installed on one side of the upper end of the installation frame 1, and the side wall of the gear 9 is meshed with the side wall of the rack 10. Two sets of sliders 8 are slidably connected to the bottom surface of the mobile frame 2, and the two sets of sliders 8 are respectively slidably connected to the two sides of the upper end of the installation frame 1. Both sides of the upper end of the installation frame 1 are provided with a limit movable frame 2, reinforcing ribs are arranged at the middle positions on both sides of the mounting frame 1. By starting the cylinder 4 and the needle suction cup 7, the telescopic end of the cylinder 4 pushes the needle suction cup 7 downward to absorb the cloth. After absorbing the cloth, the servo motor 6 is started, and the servo motor 6 drives the gear 9 to rotate, so that the gear 9 moves along the rack 10, and further drives the slider 8 under the mobile frame 2 to slide along the upper end of the mounting frame 1, and the absorbed fabric is transported to the corresponding position of the processing table 3, so that the fabric can be transferred to the original processing position accurately, and the error of further processing of the fabric can be reduced.

[0031] The technical solution provided by the utility model is as follows: first, the stacked fabrics are placed on the lifting plate 50, and by starting the electric telescopic rod 57, the telescopic end of the electric telescopic cylinder 512 is shortened to drive a group of sliding seats 58 to move close to the middle position of the bottom plate 511, and further drive the two groups of connecting rods 510 and the rotating connecting piece 59 to rotate in coordination, so that the other group of sliding seats 58 also moves synchronously. When the edge of the sliding seat 58 reaches the edge of the lifting plate 50, due to the limiting effect of the lifting plate 50, the sliding seat 58 stops moving. At this time, the four groups of sorting devices 56 at the upper end are in contact with the edges of the four corners of the fabric, which play a role in sorting and positioning the fabric. Further, by starting the two groups of vibration motors 53, the vibration motor 53 drives the L-shaped plate to move back and forth along the limiting groove 55, which plays a role in sorting and strengthening the fabric attached to one side of the L-shaped plate 52. The spring 54 plays a role in maintaining the stability of the L-shaped plate 52, so the positioning mechanism 5 can play a good role in organizing the stacked fabrics. Then, the four groups of telescopic rods 57 are started at the same time. The four groups of telescopic rods 57 are extended to drive the lifting plate 50 to move upward and separate from the bottom plate 511, and the fabric to be transported is transported to a suitable height for the needle suction cup 7 to absorb the fabric. Then, by starting the cylinder 4 and the needle suction cup 7, the telescopic end of the cylinder 4 pushes the needle suction cup 7 downward to absorb the fabric. After absorbing the fabric, the servo motor 6 is started. The servo motor 6 drives the gear 9 to rotate, so that the gear 9 moves along the rack 10, and further drives the slider 8 under the moving frame 2 to slide along the upper end of the mounting frame 1, and the absorbed fabric is transported to the corresponding position of the processing table 3, which is convenient for the fabric to be transferred to the original processing position accurately, thereby reducing the error of further processing of the fabric.

For the purpose of enabling the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model even without the description of these details.
