Hybrid type industrial robot

Abstract

The invention relates to a hybrid type industrial robot. The hybrid type industrial robot is composed of three linear motion shafts X, Y and Z, a swing shaft C and two rotary shafts A and B. Primary forms of the linear motion shafts are cantilever type (ox-head type) rectangular coordinate manipulators. The rotary shaft B is connected with the tail end of the shaft Z which does up-down linear motion. The swing shaft C and the rotary shaft A are arranged under the rotary shaft B and driven by the same. The rotary shaft A at the tail end is connected to the tail end of the swing shaft C through a connecting side plate and drives loading motion. The rotary shafts and the swing shaft actually are motion shafts at the tail end of a joint robot. Thus the hybrid type industrial robot is composed of the rectangular coordinate manipulators and the motion shafts at the tail end of the joint robot. By the hybrid type industrial robot, rapid and highly difficult reclaiming motion is achieved, load ratio is increased, use efficiency of an injection molding machine is improved, and space for mounting is smaller.

Description

technical field [0001] The invention relates to the technical field of injection molding robots, in particular to a hybrid industrial robot. Background technique [0002] Injection molding machines are often equipped with robots to improve production efficiency. At present, the simple linear (rectangular coordinate) industrial robot has gradually been unable to meet the automation needs of the current injection molding industry, and a replaceable industrial robot with better mechanical properties and flexibility is urgently needed. Although the articulated multi-degree-of-freedom robot has advantages due to its own characteristics, not only high performance but also good flexibility, but due to its high comprehensive cost and limited travel; For complex flexible trajectory movements such as moving, if the general-purpose articulated robot structure is completely used in the injection molding industry, the cost performance is low.

Problems solved by technology

At present, simple linear (rectangular coordinate) industrial robots have gradually failed to meet the automation needs of the injection molding industry, and there is an urgent need for a replaceable industrial robot with better mechanical properties and flexibility.

Although the articulated multi-degree-of-freedom robot has advantages due to its own characteristics, it not only has high performance and good flexibility, but because of its high comprehensive cost, its stroke is limited; Complicated flexible trajectory movements such as handling, if the general-purpose articulated robot structure is completely used in the injection molding industry, the cost performance is low

[0003] The existing industrial robots or manipulators used in the injection molding industry mainly have the following shortcomings: 1) It is difficult to achieve difficult and trajectory-requiring material retrieving actions; 2) The design of the fixture is difficult and the cost of replacing the fixture is high; 3) Due to the Due to design limitations, it is difficult to carry out heavy-duty design. Even if a large load can be achieved, the load ratio is small, resulting in excessive motor power; 4) It cannot be guaranteed that the movement of the large working space and certain flexibility; 5) The injection molding machine Low utilization efficiency; 6) It is impossible to ensure a small fuselage size while increasing the depth of the working space

However, it seems to be stretched for tasks such as retrieving, filming, handling and other complex flexible trajectory movements.
