Intelligent material carrying mechanical arm and carrying method

Abstract

The invention discloses an intelligent material carrying mechanical arm and carrying method. The mechanical arm comprises a mechanical carrying hand, the mechanical carrying hand comprises a first supporting arm, a second extension arm, a mechanical palm and a four-finger grabbing device; the first supporting arm is connected with the second extension arm through a hinge shaft, the second extension arm is connected with the mechanical palm through a palm turning mechanism, and the bottom end of the mechanical palm is connected with the four-finger grabbing mechanism through a four-shaft synchronous driving mechanism. The method comprises the steps that a walking carrying trolley walks to the position nearby the material, the first supporting arm, the second extension arm, the mechanical palm and the four-finger grabbing device are matched, the material is grabbed, the trolley and the mechanical arm cooperate to convey the material to the designated position, the material is loosened, the mechanical arm returns to the grabbing point to continuously grab the material, an extension oil cylinder of the second extension arm can extend, the length of the mechanical arm is prolonged, themechanical grabbing ends can rapidly approach to the material, the material grabbing efficiency and accuracy are high, the structure is simple, the cost is low, the material is not prone to being damaged due to clamping, and the material transport is more stable and reliable.

Description

technical field [0001] The invention relates to the field of intelligent handling equipment, in particular to a manipulator and a handling method for intelligent material handling. Background technique [0002] In the current material handling equipment, it can be divided into large objects and small objects. For small objects, it can be divided into two types: non-damageable and fragile. In the process of production and handling, traditional equipment is often unable to meet the requirements of fragile items, because of the strength and precision of fragile items on the handling equipment. The trajectory is strictly controlled, so companies often use manual handling. Although manual handling ensures the safety of vulnerable items, this method of handling is often inefficient and expensive, which hinders enterprises from realizing automation and improving their own competitiveness. [0003] But with the advent of manipulators, it brings a new change in the way of handling...

AI Technical Summary

Problems solved by technology

[0005] (1) In the process of logistics and express delivery, due to the large change in the size of the goods, the general size of the manipulator is fixed, so it can only grab certain goods within a fixed size range. If the goods are larger than the manipulator It is necessary to replace the manipulator with a larger size for grabbing. The manipulator can grab fewer types of goods. When it is necessary to transfer and transport goods or materials of various sizes, a variety of manipulators are needed to grab them separately. Increased material transfer costs;

[0006] (2) The manipulator is generally made of metal, so the rigidity is relatively high. When the manipulator clamps the material tightly, it is easy to cause problems such as clamping the material or deforming or slipping the material, which affects the quality of the material. If the clamping force is too loose, the material is easy to fall from the The manipulator slips and causes the consequences of handling failure, which affects the handling efficiency
