Abstract

This utility model relates to the field of automation technology, and in particular to a flexible arm material gripping device. During boxing and packaging, flexible arms and suction cups are typically used to grip materials. However, due to the depth of the box, to prevent the gripping device from hitting the box, the material is often thrown from a height to the bottom, which can easily damage the product. Furthermore, the haphazard arrangement of materials during gripping leads to poor packing results. This flexible arm material gripping device includes a cylinder, with a mounting plate fixed to the telescopic end of the cylinder. Extension plates are slidably connected to both sides of the mounting plate, and suction cups are mounted on the extension plates, each with an air tube. During the material gripping process, a vision module scans the material's placement during adsorption. The vision module then controls the rotor of a rotating slip ring to rotate, aligning the material.

[0001] This utility model belongs to the field of automation technology, and more specifically, it relates to a flexible arm material gripping device. Background Technology

[0002] When food products leave the factory, materials need to be boxed and packaged. Flexible arms and suction cups are usually used to grab the materials during the boxing and packaging process. When the flexible arm grabs and releases the materials, due to the depth of the box, in order to prevent the grabbing device from hitting the box, the materials are usually thrown from a height to the bottom of the box, which can easily lead to product damage. In addition, because the materials are placed in a messy manner when grabbing them, the boxing effect is not good.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a flexible arm material gripping device in order to achieve a more practical value. Utility Model Content

[0004] To overcome the shortcomings, the technical problem of this utility model is to provide a flexible arm material gripping device that can straighten the material, making the material more neatly arranged when loaded into the box, and can reduce the placement distance of the material when it is placed upright, preventing the product from being thrown from a height and causing damage, thus ensuring the integrity of the product.

[0005] The technical implementation scheme of this utility model is as follows: a flexible arm material gripping device includes a cylinder, an installation plate fixedly connected to the telescopic end of the cylinder, extension plates slidably connected to both sides of the installation plate, suction cups provided on the extension plates, air pipes provided on the suction cups, a diverter head connected between the air pipes on two adjacent suction cups, the diverter head being connected to the input end of the suction pump through a pipe, a rotating slip ring provided at the top of the cylinder, the cylinder being connected to the flexible arm connector through the rotating slip ring, and a vision module provided on one side of the cylinder.

[0006] Optionally, the suction cup is provided with a threaded joint and a nut is connected by the thread. Two slide grooves are opened on the two extension plates respectively, and suction cups are connected to the four slide grooves respectively. The suction cups are clamped on the slide grooves by the nuts respectively.

[0007] Optionally, the bottom of the mounting plate is longitudinally rotatably connected to a first bidirectional lead screw, and the two extension plates are threadedly connected to the first bidirectional lead screw via threaded sleeves. The bottom of one of the extension plates is laterally rotatably connected to a second bidirectional lead screw, and the two suction cups on the same extension plate are threadedly connected to the second bidirectional lead screw via threaded sleeves. The two suction cups connected to the second bidirectional lead screw are respectively fixed with sleeves, and the other two suction cups are respectively fixed with fixing rods. The two sleeves are respectively sleeved with the two fixing rods.

[0008] Optionally, the rotary slip ring consists of a stator and a rotor. The top of the stator is fixedly connected to the bottom of the flexible arm joint, and the bottom of the rotor is fixedly connected to the top of the cylinder. Both the stator and the rotor are equipped with joints, which are connected to the air pump through pipes.

[0009] Optionally, one end of the first bidirectional lead screw and the second bidirectional lead screw are respectively provided with a hexagonal hole.

[0010] Optionally, the vision module is electrically connected to a controller on the flexible arm, and the rotary slip ring is electrically connected to a controller on the flexible arm.

[0011] The present invention has the following advantages: 1. During the process of the gripping device gripping and moving the material, the vision module will scan the placement state of the material during adsorption. The vision module will cause the controller to control the rotor of the rotating slip ring to rotate, so that the material is straightened and placed more neatly when it is loaded into the box.

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] A flexible arm material gripping device, such as Figures 1-3 As shown, the device includes a cylinder 1, a mounting plate 2 fixedly connected to the telescopic end of the cylinder 1, extension plates 3 slidably connected to both sides of the mounting plate 2, suction cups 5 provided on the extension plates 3, air pipes 8 provided on the suction cups 5, and a diverter head 9 connected between the air pipes 8 on two adjacent suction cups 5. The diverter head 9 is connected to the input end of the suction pump through a pipe. A rotating slip ring 10 is provided on the top of the cylinder 1. The rotating slip ring 10 is composed of a stator and a rotor. The top of the stator is fixedly connected to the bottom of the flexible arm joint 11, and the bottom of the rotor is fixedly connected to the top of the cylinder 1. Both the stator and the rotor are provided with joints, which are connected to the air pump through pipes for use in adjusting the material placement angle.

[0024] The cylinder 1 is connected to the flexible arm joint 11 via the rotating slip ring 10. A vision module 12 is provided on one side of the cylinder 1. The vision module 12 is electrically connected to the controller on the flexible arm. The rotating slip ring 10 is electrically connected to the controller on the flexible arm. The vision module 12 is used to send signals, the controller receives signals, and the controller controls the rotor of the rotating slip ring 10 to rotate.

[0025] The suction cup 5 is provided with a threaded joint and is connected to a nut by a thread. Two slide grooves 30 are opened on the two extension plates 3 respectively, and the suction cup 5 is connected to the four slide grooves 30 respectively. The suction cup 5 is clamped on the slide groove 30 by the nuts respectively.

[0026] The bottom of the mounting plate 2 is longitudinally rotatably connected to a first bidirectional lead screw 4. Both extension plates 3 are threadedly connected to the first bidirectional lead screw 4 via threaded sleeves. The bottom of one of the extension plates 3 is laterally rotatably connected to a second bidirectional lead screw 7.
