[0023] Example 1
[0024] In one embodiment, such as Figures 1-3 As shown, an electromagnet lifting mechanism includes:
[0025] Mounting plate 1;
[0026] Fixture cover plate 8 is disposed on one side of mounting plate 1;
[0027] The fixture base 10 is located below the fixture cover plate 8;
[0028] The lifting assembly is used to drive the fixture cover plate 8 to move up and down, and is disposed between the mounting plate 1 and the fixture cover plate 8. The lifting assembly includes an upper and lower lifting cylinder structure 4, and a connecting piece is provided on the upper and lower lifting cylinder structure 4.
[0029] The connector includes a mounting bracket 3, which is connected to one side of the mounting plate 1. The upper and lower lifting cylinder structure 4 is installed on one side wall of the mounting bracket 3. The upper and lower lifting cylinder structure 4 is provided with multiple sets of upper and lower lifting cylinders. The lower end of the multiple sets of upper and lower lifting cylinders is provided with a connecting plate 5. The lower end surface of the connecting plate 5 is provided with an auxiliary plate 6. Both sides of the lower end surface of the auxiliary plate 6 are provided with a set of large electromagnets 7. The lower end surfaces of the two sets of large electromagnets 7 are connected to the upper end surface of the fixture cover plate 8.
[0030] A cover plate base 9 is installed on the outer side of the fixture cover plate 8; a base frame plate 11 is installed on the outer side wall of the fixture base 10; a base plate 12 is provided on the lower end surface of the base frame plate 11; multiple sets of small electromagnets 13 are provided on the upper end surface of the base plate 12, and the multiple sets of small electromagnets 13 are respectively connected to the outer walls on both sides of the base frame plate 11; a positioning element 14 is provided on one side of the small electromagnet 13, and the positioning element 14 is installed on one side of the base frame plate 11 and the upper end surface of the base plate 12; by setting the positioning element 14, the small electromagnet 13 can be positioned and supported, thereby improving the stability of the installation of the small electromagnet 13.
[0031] Specifically, during use, the large electromagnet 7 is energized, attracting the entire fixture cover plate 8 and cover plate base 9. The upward lifting cylinder structure 4 is then pulled upwards, causing multiple sets of lifting cylinders to raise the fixture cover plate 8 and cover plate base 9. A robotic arm then places the product onto the upper surface of the fixture base 10. Next, the multiple sets of lifting cylinders are pulled downwards, covering the product with the fixture cover plate 8 and cover plate base 9, clamping and fixing the product for cutting. During cutting, the small electromagnet 13 is energized, attracting the fixture cover plate 8 and cover plate base 9 to prevent the entire assembly from shifting. When the product needs to be removed after cutting, the small electromagnet 13... When the power is off, multiple sets of lifting cylinders are pulled upwards, causing the fixture cover plate 8 and the cover plate base 9 to be lifted by the attraction of the large electromagnet 7. The robot arm can then remove the product, which is quite convenient. By setting up a lifting assembly consisting of fixture cover plate 8, fixture base 10, lifting cylinder structure 4 and connecting parts, the fixture cover plate 8 can be lifted and moved on the fixture base 10, which facilitates the clamping and fixing of the product. At the same time, the small electromagnet 13 can attract and fix the fixture base 10, preventing the product from moving during the cutting process. This improves the work quality and efficiency of product cutting. In addition, the structure is compact, solving the problem of complex processing and high cost of tray structures, resulting in a cost-effective and efficient structure.
[0032] Example 2
[0033] In one embodiment, such as Figures 1-2 As shown, multiple sets of mounting holes 2 are provided on both sides of the mounting plate 1. By providing multiple sets of mounting holes 2, it is easy to install and fix the mounting plate 1.
[0034] The above embodiment discloses an electromagnet lifting mechanism. In use, the large electromagnet 7 is energized, attracting the entire fixture cover plate 8 and cover plate base 9. The upward lifting cylinder structure 4 is pulled upward, causing multiple sets of upward lifting cylinders to lift the fixture cover plate 8 and cover plate base 9. Then, a robotic arm places the product on the upper surface of the fixture base 10. Then, multiple sets of upward lifting cylinders are pulled downward, covering the upper end of the fixture cover plate 8 and cover plate base 9 with the product, clamping and fixing the product for cutting. During the cutting process, the small electromagnet 13 is energized, attracting the fixture cover plate 8 and cover plate base 9 to prevent the whole assembly from moving. When the product needs to be removed after cutting, the small electromagnet 13 is de-energized, and multiple sets of upward lifting cylinders are pulled upward, causing the fixture cover plate 8 and cover plate base 9 to be lifted by the attraction of the large electromagnet 7. The robotic arm can then remove the product, which is quite convenient.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
