DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] A multi-gripper quick unloading device for an automatic material laying and marking machine, such as Figures 1 to 4 As shown, it includes a frame 12, on which a conveyor belt 1 for transmitting materials is arranged, a mounting seat 5 is slidably arranged on the frame 12, and a plurality of grippers 4 capable of adsorbing materials on the conveyor belt 1 are arranged on the mounting seat 5. In this specific embodiment, there are a total of ten grippers 4, and they are arranged perpendicular to the transmission direction of the conveyor belt 1, and a distance adjusting member 3 for driving the grippers 4 to slide away from the conveyor belt 1 is arranged on the mounting seat 5. On the automatic material laying and marking machine, the frame 12 is provided with a loading plate 11 capable of carrying materials unloaded by the grippers 4 below the sliding path of the plurality of grippers 4, and the plurality of materials unloaded by the grippers 4 on the loading plate 11 are stacked into a plurality of piles, and an image acquisition unit for controlling the grippers 4 to adsorb materials is arranged on the frame 12. In this specific embodiment, a longitudinal transmission member 2 for sliding in the same direction as the arrangement direction of the conveyor belt is arranged on the transmission mounting seat 5;

[0023] Usage: After the material is marked by the marking machine, the gripper 4 transfers the material row by row to the same position on the carrier 11. The gripper 4 continuously transfers the material, so that the material is gradually transferred to the carrier 11 and stacked up. Since the total number of materials marked by the marking machine each time is limited and the marking time is long, there is enough time to transfer all the stacked materials to the next process.

[0024] Practical effect: Compared with the prior art, the materials that are about to leave the conveyor belt 1 in rows are uniformly piled on the loading plate 11 through the gripper 4, which effectively relieves the work pressure of the employees.

In this specific embodiment, the automatic material laying and marking machine brings the material punched out by the punch to the conveyor belt 1. Each row of materials punched out by the punch is usually not arranged in the same direction. Therefore, in order to make the materials stacked on the carrier plate 11 have a unified direction, the axis of the adsorption head is coaxially arranged with the axis of the outer shell, and the image acquisition unit is also used to control the material on each gripper 4 to rotate to the same direction. Furthermore, for materials with complex shapes, in order to make the gripper 4 adsorb the materials more stably, the adsorption head is provided with a plurality of through holes connected to the inner tube, and the plurality of through holes are evenly arranged around the axis of the adsorption head.

[0026] In order to reduce the squeezing effect on the material when the adsorption head slides up and down close to the conveyor belt 1, the adsorption head is slidably connected to the inner tube, and a spring is arranged between the adsorption head and the mounting seat 5, and the two ends of the spring are respectively in contact with the mounting seat 5 and the adsorption head.

[0027] like Figures 1 to 4 As shown, in order to facilitate the transportation of materials, a discharging assembly capable of carrying a plurality of materials stacked on a loading plate 11 is provided on the frame 12, and a transverse transmission member 6 for driving the discharging assembly to slide in the transmission direction of the vertical conveyor belt 1 is provided on the frame 12, and a plurality of slots 111 are provided at intervals on the loading plate 11, and the discharging assembly comprises a connecting member 8, a claw plate 9 and a lifting member 7, and the connecting member 8 and the lifting member 7 are both fixedly connected to the transverse transmission member 6, and the lifting member 7 is used to locate the rotation angle of the claw plate 9 and the connecting member 8, and a plurality of claw strips 901 that can move through a plurality of slots 111 are formed on the end of the claw plate 9 away from the connecting member 8.

Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
