Claims

1. A robot with safety protection, characterized by, include: The card issuing part (1) and the connecting part (2) are provided. The card issuing part (1) includes a collision part (11) and a fixing part (12). The collision part (11) is connected to the fixing part (12) by magnetic attraction. The fixing part (12) and the collision part (11) are connected by a traction part (3) to prevent the collision part (11) from falling to the ground and causing the cable between the fixing part (12) and the collision part (11) to break. The end of the fixing part (12) away from the collision part (11) is screwed onto the connecting part (2). The end of the connecting part (2) away from the fixing part (12) is screwed onto the card issuing machine.

2. The robotic arm with safety protection according to claim 1, characterized in that: The fixed part (12) and the collision part (11) are respectively provided with a first magnetic part (4) and a second magnetic part (5) at their adjacent ends. When the collision part (11) does not fall off, the first magnetic part (4) and the second magnetic part (5) are magnetically attached to each other.

3. The robot arm with safety protection according to claim 2, characterized in that: The first magnetic part (4) includes a first fixing seat (41) and a magnet sleeve (42), and the second magnetic part (5) includes a second fixing seat (51) and a magnet (52). The magnet sleeve (42) has a magnet core (421) inside, and the magnet (52) and the magnet core (421) attract each other.

4. The safety protected robot arm of claim 3, wherein: The edge of the magnet sleeve (42) is symmetrically provided with two positioning pins (422), and the corresponding magnet (52) is provided with a positioning hole that matches the positioning pin (422) to prevent the collision part (11) and the fixing part (12) from being misaligned.

5. The safety protected robotic arm of claim 2, wherein: The traction part (3) passes through the first magnetic part (4) and the second magnetic part (5) and forms a through hole (6) for guiding the traction part (3).

6. The safety protected robotic arm of claim 3, wherein: The magnet is equipped with a switch (7). When the collision part (11) has not fallen off, the switch (7) is closed. When the collision part (11) falls off, the switch (7) is opened and the robotic arm stops moving.
