Description

Technical Field

[0001] This utility model relates to the field of plate handling technology in crane production lines, specifically to a plate handling assembly. Background Technology

[0002] The handling of sheet metal on a crane production line, moving it from one location to another, is done using handling equipment. The selection of lifting devices is very important during handling. Generally, the lifting devices used for handling include electromagnetic chucks, vacuum chucks, or mechanical clamps.

[0003] Electromagnetic chucks have the advantages of small size, strong suction, safety and long service life. However, electromagnetic chucks have high requirements for the flatness of the board surface, and the board that loses the magnetic attraction of the electromagnetic chuck may suddenly fall off during unloading.

[0004] Vacuum suction cups have the advantages of high safety, light weight, and good surface adaptability. When the power is off, the suction cup will slowly release the board to prevent it from falling suddenly. However, vacuum suction cups have low load-bearing capacity and are prone to wear, requiring regular replacement.

[0005] Therefore, both have their own advantages. Currently, most production lines use a single suction cup method for material handling, which is not very adaptable. Using both methods in combination not only combines the advantages of both methods but also reduces the impact of their disadvantages. For this reason, we provide a sheet metal handling assembly. Utility Model Content

[0006] The purpose of this utility model is to provide a plate handling assembly that solves the problem that most current crane production lines use a suction cup method for handling, which is not very adaptable.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal handling assembly, including an industrial robot and a handling frame installed at the end of the industrial robot. A buffer-type electro-permanent magnet clamp, a vacuum suction cup clamp, and a fixed electro-permanent magnet clamp are respectively installed on the handling frame along a direction perpendicular to the handling frame. The bottom height of the vacuum suction cup clamp is higher than the bottom height of the buffer-type electro-permanent magnet clamp, and the bottom height of the buffer-type electro-permanent magnet clamp is higher than the bottom height of the fixed electro-permanent magnet clamp. The buffer-type electro-permanent magnet clamp, vacuum suction cup clamp, and fixed electro-permanent magnet clamp on the handling frame are rotationally symmetrically distributed.

[0008] Preferably, the buffered electro-permanent magnet clamp and the vacuum suction cup clamp are mounted on the long side beam of the transport frame via a mounting frame one. The electro-permanent magnet mounting rod of the buffered electro-permanent magnet clamp passes through the mounting frame one. The electro-permanent magnet mounting rod of the buffered electro-permanent magnet clamp is clamped on the mounting frame one via an upper and lower nut seat and a spring. The spring provides elastic support between the mounting frame one and the electro-permanent magnet block.

[0009] The suction cup mounting rod of the vacuum suction cup clamp passes through the mounting frame one, and the suction cup mounting rod of the vacuum suction cup clamp is clamped on the mounting frame one by two sets of limit nuts installed at the top and bottom.

[0010] Preferably, the mounting bracket is L-shaped and is fixed to the transport frame by bolt fasteners.

[0011] Preferably, the fixed electro-permanent magnet clamp is mounted on the short side crossbeam of the transport frame via a second mounting bracket, and the second mounting bracket is fixed to the transport frame by bolt fasteners.

[0012] Preferably, at least two sets of the fixed electro-permanent magnet clamps are provided, and the fixed electro-permanent magnet clamps are installed in the middle of the short side crossbeam of the conveying frame.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes a transport frame to install three different types of clamps: a buffer-type electro-permanent magnet clamp, a vacuum suction cup clamp, and a fixed electro-permanent magnet clamp, each installed at a different height. The buffer-type electro-permanent magnet clamp first magnetically attracts the sheet material. The vacuum suction cup clamp, with its lowest installation height, acts as a contact buffer during the attraction process, ensuring a more stable and reliable hold, preventing damage to the buffer-type clamp. Then, the fixed electro-permanent magnet clamp, with its higher installation height, adheres to the sheet material. Both the buffer-type and vacuum suction cup clamps are elastic to adapt to the attraction height of the fixed electro-permanent magnet clamp. The fixed electro-permanent magnet clamp further stabilizes the sheet material during transport, preventing it from wobbling. Each type of clamp has its own advantages, resulting in greater stability and security during transport, thus improving safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a sheet metal handling assembly, including an industrial robot 1 and a handling frame 2 installed at the end of the industrial robot 1. A buffered electro-permanent magnet clamp 3, a vacuum suction cup clamp 4 and a fixed electro-permanent magnet clamp 5 are respectively installed on the handling frame 2 along the direction perpendicular to the handling frame 2. The buffered electro-permanent magnet clamp can not only buffer the impact force when the sheet metal is initially adsorbed, but also better adapt to the vacuum suction cup clamp 4 and the fixed electro-permanent magnet clamp 5, playing a coordinating role.

[0023] The buffer-type electro-permanent magnet clamp 3 and the vacuum suction cup clamp 4 are mounted on the long side beam of the transport frame 2 via the mounting bracket 6. The mounting bracket 6 is L-shaped and is fixed to the transport frame 2 by bolt fasteners.

[0024] The permanent magnet mounting rod 31 of the buffered electro-permanent magnet clamp 3 passes through the mounting frame 6. The permanent magnet mounting rod 31 of the buffered electro-permanent magnet clamp 3 is clamped on the mounting frame 6 through the upper and lower nut seats 32 and the spring 33. The spring 33 is elastically supported between the mounting frame 6 and the electro-permanent magnet block.

[0025] The suction cup mounting rod 41 of the vacuum suction cup clamp 4 passes through the mounting frame 6. The suction cup mounting rod 41 of the vacuum suction cup clamp 4 is clamped on the mounting frame 6 by two sets of limit nuts 42 installed at the top and bottom.

[0026] The fixed electro-permanent magnet clamp 5 is installed on the short side crossbeam of the transport frame 2 via mounting bracket 2 7. Mounting bracket 2 7 is fixed to the transport frame 2 by bolt fasteners. At least two sets of fixed electro-permanent magnet clamps 5 are provided, and the fixed electro-permanent magnet clamps 5 are installed in the middle of the short side crossbeam of the transport frame 2.

[0027] Furthermore, the bottom height of the vacuum suction cup clamp 4 is higher than the bottom height of the buffer electro-permanent magnet clamp 3, and the bottom height of the buffer electro-permanent magnet clamp 3 is higher than the bottom height of the fixed electro-permanent magnet clamp 5. The buffer electro-permanent magnet clamp 3, vacuum suction cup clamp 4 and fixed electro-permanent magnet clamp 5 on the transport frame 2 are rotationally symmetrically distributed to ensure the overall balance.

[0028] In use, the buffer-type electro-permanent magnet clamp 3, which is closer to the board and has a stronger suction force, first magnetically attracts the board. During the attraction process, the board comes into contact with the vacuum suction cup clamp 4, which has the lowest installation height. The vacuum suction cup clamp 4 acts as a contact buffer during the attraction process, making the board more stable and reliable, and less likely to be damaged by the buffer-type electro-permanent magnet clamp 3. Then, the board is attracted by the fixed electro-permanent magnet clamp 5, which has a higher installation height. The elasticity of the spring 33 of the buffer-type electro-permanent magnet clamp 3 and the deformation elasticity of the vacuum suction cup clamp 4 are both elastic to adapt to the attraction height of the fixed electro-permanent magnet clamp 5, so that the board can be attracted and fixed by the three clamps at the same time for transportation. The fixed electro-permanent magnet clamp 5 makes the board more stable during transportation and less prone to shaking. Each of the three clamps has its own advantages, making the board more stable and secure during transportation and improving safety.
