Problems solved by technology

[0003] However, there is a certain error in judging the safe distance between the manipulator and live equipment only based on the subjective experience of the operator, and it is easy for the operator to ignore the distance between the manipulator and the equipment when he focuses on the work content. Therefore, the above technical solution is not effective Ensure safe operation of equipment

Embodiment 1

[0031] Attached below Figure 1-Figure 2 The present invention is described in detail, specifically, the structure is as follows:

[0032] This embodiment provides a safety anti-collision system under the operating state of the manipulator, which is mainly used for safety protection under the operating state of the large-scale heavy-duty multi-degree-of-freedom manipulator, including the first anti-collision system and the second anti-collision system, the first The anti-collision system is a multi-layer protective layer laid on the surface of the robot arm, and the second anti-collision system is a safety protection bracelet worn by construction workers. In this embodiment, the protection layer is configured as a rectangle.

[0033] The first anti-collision system includes a rigid protective layer 5, a piezoelectric vibration induction layer 4, a first flexible protective layer 3, an electrostatic induction layer 2 and a second flexible protective layer 1 laid out from the s...

Abstract

The invention discloses a safety anti-collision system under the working state of a mechanical arm. Induction layer, first flexible protection layer, electrostatic induction layer and second flexible protection layer, wherein, the rigid protection layer is used for bonding with the surface of the robotic arm, the electrostatic induction layer has a conductor layer, and a low-voltage alternating current electric field can be formed in the conductor layer ; The second anti-collision system includes a safety protection bracelet that can sense position information and issue an alarm signal. The invention adopts a comprehensive way of multiple safety protection systems, has high detection precision and fast response speed.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a safety anti-collision system in the working state of a mechanical arm. Background technique [0002] When the manipulator is working on site, the operator needs to observe the operation of the manipulator at close range, and adjust the manipulator in real time according to his own work experience. When the operator judges that the distance between the robot arm and other equipment and workpieces is greater than the safety distance, it is determined that the robot arm can operate according to the set trajectory; when the operator judges that the distance between the robot arm and other equipment and workpieces is at a critical safety distance , the operator needs to immediately adjust the robotic arm to a position greater than the safety distance, and reset the operating track of the robotic arm to ensure the safe operation of the robotic arm. [0003] However, there ...
