The design of a robotic arm needs to meet a variety of requirements, the following are some of the main aspects:
1, the functional requirements:
Capable of completing the predetermined tasks, such as gripping, handling, assembly, welding, etc., to meet the operational needs of a particular work scene.
With sufficient precision and repeatable positioning accuracy to ensure the stability of work quality.
2, motion performance:
Have a suitable workspace, can cover the required operation area.
Have good speed, acceleration and smoothness of movement to improve efficiency and reduce vibration.
3, load capacity:
Capable of withstanding the weight of the object to be grasped or operated, while ensuring structural stability and movement accuracy under load.
4, structural strength and rigidity:
Capable of withstanding all kinds of forces and moments in the work, including inertia force, gravity, friction, etc., to prevent deformation and damage.
5, size and weight:
In order to meet the function and performance of the premise, try to reduce the size and weight, in order to reduce the requirements for the installation of the foundation and drive system.
6, reliability and stability:
The use of high-quality materials and reliable manufacturing process, to ensure stable operation for a long time, reduce the probability of failure.
7, safety:
Designed guards and safety mechanisms to prevent harm to personnel and equipment.
With overload protection, emergency stop and other functions.
8, control performance:
Compatible with the control system, rapid response, high control accuracy.
9, maintenance and repair convenience:
Structural design to facilitate routine maintenance and fault repair, reduce downtime and maintenance costs.
10, cost-effective:
In the premise of meeting the design requirements, to control the manufacturing cost and the cost of use, improve the cost-effective.
For example, the design of robotic arms in automobile production lines needs to be able to quickly and accurately carry out the assembly of parts and components, and at the same time be able to withstand heavy loads, and remain stable and reliable in a long period of continuous work. The minimally invasive surgical robotic arms in the medical field, on the other hand, pay more attention to precision, flexibility and safety.
