On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0021] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0022] A magnetic gripper with an anti-collision structure includes a robotic arm 1. An electromagnetic suction cup 2 is installed at the upper end of the robotic arm 1. A base 3 is provided at the bottom of the robotic arm 1. A mounting plate 4 is provided at the bottom of the base 3.

A second spring shock absorber 13 is provided inside the sleeve 12. A telescopic rod 14 is sleeved inside the sleeve 12 and above the second spring shock absorber 13.

[0023] In this embodiment, the electromagnetic suction cup 2 and the robotic arm 1 are designed as a single integrated structure. The robotic arm 1 is fixedly welded to the base 3, and the base 3 is slidably connected to the mounting plate 4. The first slider 6 is sized and matched to the first slide groove 5, and the first slider 6 is slidably connected to the first slide groove 5. The first spring damper 7 is located inside the first slide groove 5, and both ends of the first spring damper 7 are fixedly connected to the inner walls of the first slider 6 and the first slide groove 5, respectively. The second slider 10 is sized and matched to the second slide groove 9, and the second slider 10 is slidably connected to the second slide groove 9. The telescopic rod 1... The outer diameter of the telescopic rod 14 is matched with the inner diameter of the sleeve 12, and the telescopic rod 14 is connected to the sleeve 12 by a sliding connection. The sleeve 12 is connected to the first hinge seat 8 by a rotating connection, and the telescopic rod 14 is connected to the second hinge seat 11 by a rotating connection.
