Description

Technical Field

[0001] The utility model relates to the technical field of wire tray stacking, and more specifically to a multifunctional clamp for wire tray stacking. Background Art

[0002] Copper wire is a kind of metal conductive material. The main material is copper metal. It is generally used in industrial construction. In life, copper wire is used as a conductor. It has good conductivity and is widely used in the manufacture of wires, cables, brushes, etc. After the production and processing of copper wire is completed, it needs to be wound on the wire drum and then stacked.

[0003] During the palletizing process, after one layer of palletizing is completed, a piece of separator paper needs to be placed on the first layer of palletized wire drums before the second layer of palletizing is carried out. With the continuous improvement of the automation of production equipment, palletizing also uses a robotic arm and a robotic claw for clamping and palletizing. However, the robotic arm cannot clamp the separator paper, so it is necessary to manually place the separator paper on the wire drum. In this way, the staff observes the palletizing situation at any time and then prepares the placement of the separator paper, which is more troublesome to operate. Furthermore, only one set of mechanical claws is usually installed at the end of the palletizing robot arm. A set of mechanical claws can only grab wire drums of one specification. When palletizing wire drums of other specifications, other types of air claws need to be reinstalled, which is troublesome to operate and wastes time, resulting in low work efficiency.

[0020] 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.

[0021] refer to Figure 1-2 A multifunctional fixture for stacking wire drums, comprising a fixed disk 1 and a main arm 2 vertically mounted on the end face of the fixed disk 1, wherein a first connecting arm 21, a second connecting arm 22 and a third connecting arm 23 are vertically mounted on a plane at one end of the main arm 2 away from the fixed disk 1; a first air gripper 3 and a second air gripper 4 are respectively mounted at one end of the first connecting arm 21 and the second connecting arm 22 away from the main arm 2, and a fixing frame 5 is vertically mounted at one end of the third connecting arm 23 away from the main arm 2; at least three gas rods 7 that are not in a straight line are vertically mounted on one side of the fixing frame 5 away from the third connecting arm 23, wherein the gas rod 7 is elastically telescopically connected to the fixed frame 5 and a suction cup 8 is mounted at one end away from the fixed frame 5, and a pneumatic device with suction and deflation functions is connected to the end of the gas rod 7 away from the suction cup 8 through an air pipe 73. It can be understood that the fixed disk 1 is used to connect the end of the robot arm, which can be a flange, and is installed and fixed by bolts. The first air gripper 3 and the second air gripper 4 are both claw-like structures, which are used to grab the wire reel. The air gripper is a prior art, and the pneumatic device is also an existing equipment, which will not be described in detail here. Since the fixed frame 5 is perpendicular to the third connecting arm 23, and the air rod 7 is perpendicular to the fixed frame 5, the axial direction of the air rod 7 is parallel to the axial direction of the third connecting arm 23, that is, the third connecting arm 23 is facing downward, and the suction cup 8 installed on the air rod 7 is also facing downward. The air rod 7 is a tubular structure, which is connected to the air pipe 73 at the top and the suction cup 8 at the bottom. When the suction cup 8 is pressed on the separator paper 9, the pneumatic device sucks out the air in the suction cup 8 through the air pipe 73 and the air rod 7. Due to the effect of atmospheric pressure, the suction cup 8 can firmly suck the separator paper 9. The three air rods 7 are connected to the three suction cups 8, and the three suction cups 8 that are not in the same straight line are sucked on the separator paper 9 to make the suction more firm. The gas rod 7 is elastically connected to the fixing frame 5 , and the gas rod 7 can be elastically extended and retracted up and down, and when the separation paper 9 is bent, it can also ensure that each suction cup 8 can be pressed on the separation paper 9 .

[0022] In some embodiments, the angle between the adjacent first connecting arm 21, second connecting arm 22 and third connecting arm 23 is 90 degrees. Here, the first connecting arm 21 can be perpendicular to the second connecting arm 22 and the third connecting arm 23. Or, the second connecting arm 22 can be perpendicular to the first connecting arm 21 and the second connecting arm 22. Or, the third connecting arm 23 can be perpendicular to the first connecting arm 21 and the second connecting arm 22. In short, when the main arm 2 rotates 90 degrees, it can switch to another workstation.

[0023] In some embodiments, the first air gripper 3 and the second air gripper 4 are of different models. Air grippers of different models can clamp wire reels of different models. When wire reels of different models are produced on the assembly line, the air grippers can be switched by rotating the main arm 2 to apply the corresponding wire reels.

[0024] In some embodiments, the fixing frame 5 is provided with a through hole 6 that is movably engaged with the gas rod 7, and a limit block 71 with a diameter larger than the through hole 6 is installed on the top of the gas rod 7 above the through hole 6, and a spring 72 is sleeved on the gas rod 7 between the suction cup 8 and the through hole 6. The limit block 71 can be threadedly connected to the top of the gas rod 7 by a nut, which can prevent the gas rod 7 from slipping out of the through hole 6. The bottoms of the multiple suction cups 8 are in the same horizontal plane in a natural state, which is suitable for the paper separator 9 to be flat. When the paper separator 9 is uneven, each suction cup 8 is required to be at different heights to be sucked on the surface of the paper separator 9. Therefore, after pressing down the suction cup 8, the gas rod 7 can elastically slide up and down in the through hole 6 to adapt to the uneven paper separator 9.

[0025] In some embodiments, the fixing frame 5 includes a base plate 51 vertically connected to the third connecting arm 23, and the base plate 51 extends outward in four directions to form four extension plates 52, and the through hole 6 is opened on the extension plate 52. After the gas rod 7 is installed in the through hole 6, the gas rod 7 and the suction cup 8 are arranged in a square row. The suction cup 8 sucks on four square points on the separation paper 9 to ensure the stability of suction.

[0026] In some embodiments, the fixed disk 1 is connected to the end of the robot arm for use. The robot arm is a prior art, which is not shown in the figure and will not be described in detail here. When in use, after the robot arm grabs the wire drum with the first air gripper 3 or the second air gripper 4 to stack a layer, the robot arm rotates the main arm 2 so that the suction cup 8 faces downward, and then moves to the top of the separator paper 9, presses the suction cup 8 down to absorb the separator paper 9, and then moves the separator paper 9 to the wire drum, and then rotates the main arm 2 again so that the first air gripper 3 or the second air gripper 4 continues to grab and stack downward. Repeat the work.

[0027] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
