[0002] Rebar refers to a strip made of steel, usually round in shape. It is a structural material used to enhance the tensile strength of concrete structures. The main function of rebar in concrete is to withstand tensile stress to make up for the lack of concrete's own tensile resistance. Rebar is a commonly used building material and is widely used in construction projects. It has the characteristics of high strength, corrosion resistance, and strong tensile resistance, and is widely recognized and used.

In order to avoid the random stacking of stirrups formed by the rebar hoop bending machines, which is too messy, the messy steel bars need to be stacked neatly. At present, the processed stirrups are usually stacked neatly by hand. Manual stacking of stirrups is slow, time-consuming and labor-intensive, with low work efficiency, high work intensity and low degree of automation. In addition, when the stirrups fall during the stacking process, it is easy to cause injuries to workers, which is dangerous. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a semi-finished steel bar automatic grabbing and stacking device includes a robot arm 1, a fixed plate 2, a cylinder 3, a cylinder body 4, a connecting block 5 and a clamping plate 6. The number of the cylinder 3 is at least one. The fixed plate 2 is arranged on the robot arm 1, and the cylinder 3 is arranged on the fixed plate 2. The cylinder 3 can rotate around itself and can make a linear motion relative to the fixed plate 2. The cylinder 3 includes a cylinder body 4. Two connecting blocks 5 are symmetrically arranged on the cylinder body 4. The connecting blocks 5 are fixedly connected to the clamping plates 6. The two connecting blocks 5 can drive the two clamping plates 6 to move simultaneously under the action of the air source. The two connecting blocks 5 can drive the clamping plates 6 to move towards each other to clamp the stirrups or move away from each other to loosen the stirrups under the action of the air source, thereby realizing the clamping and stacking of the stirrups, and realizing the absence of manual stacking. When grabbing stirrups of different specifications through the above-mentioned cylinder 3, it is only necessary to adjust the position of the cylinder 3 and the grabbing direction by combining the rotating cylinder 3 itself and the moving cylinder 3, so as to better grab the stirrups and prevent the stirrups from falling during the grabbing process, thereby improving the efficiency of stacking the stirrups and reducing the labor intensity and safety hazards of manual labor.

[0021] like Figure 1-Figure 4 As shown, a plurality of fixing holes 7 are provided at the center of the fixing plate 2, and bolts are provided in the fixing holes 7 to fix the fixing plate 2 to the robot arm 1. At least one elongated hole 8 is provided in the circumferential direction at the center of the fixing plate 2, and the elongated hole 8 is movably connected to an adjusting plate 9 through bolts and nuts. The cylinder 3 is fixedly connected to the bottom of the adjusting plate 9, and two arc holes 10 arranged oppositely are provided on the adjusting plate 9, and the centers of the two arc holes 10 coincide with each other. The bolts for installing the cylinder 3 pass through the elongated holes 8 and the arc holes 10, and the diameter of the bolts for installing the cylinder 3 is smaller than the width of the arc holes 10, thereby ensuring that the arc holes 10 and the bolts can slide relative to each other, so that the adjusting plate 9 can rotate with the center of the arc holes 10 as the center when supported by the bolts, and two shock-absorbing columns 11 are symmetrically arranged between the adjusting plate 9 and the cylinder 3.

[0022] Among them, the fixed disk 2 is a circular structure, and a plurality of fixing holes 7 are provided along the circumferential direction at its center position. The fixing hole 7 can be fixedly connected to the robot arm 1 by passing bolts through the fixing holes 7. The fixed disk 2 is provided with at least one wire hole along the circumferential direction at the center position. Specifically, the wire hole is located between the fixing hole 7 and the center of the fixed disk 2. By setting the wire hole, the cable connected to the cylinder 3 can be passed through to connect the electronic control system. At least one elongated hole 8 is evenly distributed along the circumference on the fixed disk 2 for installing the above-mentioned at least one cylinder 3. In this embodiment, each elongated hole 8 is provided corresponding to a cylinder 3. There are eight elongated holes 8, and they are opened in a square shape on the fixed disk 2. The number and combination shape of the elongated holes 8 can be set as needed, and are not limited to the combination shape of eight and square. The shape of the fixed disk 2 is not limited to a circle, but can also be other shapes such as a square and a rectangle.

[0023] The cylinder 3 can rotate around itself and make linear motion relative to the fixed plate 2, wherein the linear motion relative to the fixed plate 2 means that the cylinder 3 can make linear motion along the above-mentioned elongated hole 8, and the position of the cylinder 3 can be adjusted by rotating around itself and making linear motion, so as to adjust the cylinder 3 to the best clamping position of the stirrups, so as to better clamp stirrups of different shapes and specifications.

[0024] At least one adjusting plate 9 is provided, and two are provided in the present embodiment. Two arc holes 10 are provided opposite to each other on the adjusting plate 9, and the centers of the two arc holes 10 coincide with each other. Bolts are passed through the elongated hole 8 and the arc hole 10, and the adjusting plate 9 can be connected to the fixed plate 2 through nuts, so that the adjusting plate 9 can make a linear motion in the elongated hole 8, and can rotate with the center of the arc hole 10 as the center. The cylinder 3 is fixedly connected under the adjusting plate 9, and then the linear motion of the adjusting plate 9 can drive the cylinder 3 to make a linear motion. The rotation of the adjusting plate 9 can change the grabbing direction of the two connecting blocks 5 of the cylinder 3, so as to facilitate the grabbing and stacking of stirrups of different shapes.

[0025] In the specific implementation process, firstly, the fixing plate 2 is connected to the robot arm 1 by passing the bolts through the fixing holes 7, and then the position of the adjusting plate 9 is adjusted according to the stirrups of different shapes and specifications. In the production process of stirrups, after the steel bars are bent and formed, before the shearing mechanism on the side cuts them, the robot arm 1 is controlled to make the two sides of the stirrups respectively located between the connecting blocks 5 of the two groups of cylinders 3. The connecting blocks 5 grab the stirrups under the action of the cylinders 3, and then the shearing mechanism on the side cuts the steel bars. During the cutting process, the vibration generated by the stirrups is prevented from being damaged by the shock-absorbing effect of the shock-absorbing column 11. After the cutting is completed, the robot arm 1 puts the formed stirrups in the designated position, the cylinder 3 drives the connecting block 5 to loosen, the robot returns to the initial position, and then performs the next cycle.

[0026] Working process: the robot arm 1 makes the two sides of the stirrups located between the connecting blocks 5 of the two groups of cylinders 3 respectively. The connecting blocks 5 grab the stirrups under the action of the cylinders 3, and the shearing mechanism on the side cuts the steel bars. After cutting, the robot arm 1 puts the formed stirrups in the designated position, and the cylinders 3 drive the connecting blocks 5 to release, and the robot returns to the initial position, and then performs the next cycle.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
