[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The anti-collision mechanism of this utility model effectively absorbs and disperses impact forces when the device is subjected to external collisions through the interaction of the plate, protruding block, connecting rod, sliding block, connecting shaft, and compression spring. The initial shock-absorbing effect of the shock-absorbing column combined with the secondary offsetting effect of the compression spring significantly reduces the impact of external collisions on the device itself, thereby protecting the device and its internal components from damage. This design not only improves the durability and stability of the device, but also extends its service life and reduces maintenance costs.
[0015] 2. The utility model can flexibly adapt to objects of different sizes and shapes by adjusting the height and angle of the first rod and the second rod through the controller. The start-up of the drive motor can drive the linkage of the spiral rack, the first gear and the second gear, thereby realizing the synchronous movement of the clamping hand, the second connecting rod and the third connecting rod to complete the clamping of the object. The introduction of the reset spring not only ensures the stability and reliability of the clamping process, but also can use the reaction force to reset the clamping mechanism after the clamping is completed, so as to facilitate the next operation. The design of this clamping mechanism not only improves the degree of automation and work efficiency of the device, but also enhances its adaptability and flexibility, and is suitable for a variety of application scenarios.

[0027] The working principle of a robot anti-collision device proposed by the present invention is that when the device is moving and is hit by external forces, the plate 2 will move toward the base 10. At this time, the shock-absorbing column 9 can play a preliminary shock-absorbing role to offset the external impact force. At the same time, the plate 2 drives the protruding block 3 to move during the movement, thereby driving the connecting rod 4 to rotate, and then driving the sliding block 5 to slide along the connecting shaft 6, so that the two sliding blocks 5 move toward the central axis of the connecting shaft 6 at the same time, and then squeeze the compression spring 8, so as to offset the external impact force for a second time, and with the repeated contraction and reset of the compression spring 8, most of the impact force can be offset, thereby protecting the device.
[0028] It is worth noting that when an object needs to be clamped, it is only necessary to activate the clamping mechanism.

At this time, the reset spring 24 undergoes elastic deformation and maintains a certain tension.
