Problems solved by technology

[0003] The purpose of the present invention is to provide a controllable palletizing device with a large working space. All driving motors are installed on the frame, which can solve the problem that the motors of the traditional open-chain series palletizing robot are installed at its hinges, which causes the arm to be heavy, Poor rigidity, large inertia, accumulation of joint errors and other problems, the robot has better dynamic performance and can better meet the requirements of high-speed heavy-load handling and palletizing

Abstract

The invention relates to a large-workspace controllable stack device. The stack device comprises a large arm swing branched chain, a middle arm swing branched chain, a small arm swing branched chain, a posture maintaining branched chain, an end actuator and a rack. A robot completes work of the carrying stack with large workspace and flexible track output through combined motion of the large arm swing branched chain, the middle arm swing branched chain and the small arm swing branched chain. During operation, three groups of parallelogram structures of the posture maintaining branched chain can guarantee the end actuator to be in a horizontal state. All servo motors are installed on the rack, bars are light, the motion inertia of the robot is small, the dynamics performance is good, and the requirement for the high-speed overload carrying stack can be better satisfied.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a controllable palletizing device with a large working space. Background technique [0002] Palletizing robots are widely used in automatic handling operations such as machine tool loading and unloading, automatic production lines of stamping machines, automatic assembly lines, handling and palletizing, and containers. The existing palletizing robots mainly have three structural types: Cartesian coordinate type, cylindrical coordinate type and joint type. Among them, the articulated palletizing robot has gradually become the most important structural form of palletizing robots because of its compact structure, flexible movements, small footprint, and large working space. However, the drive motors of such traditional open-chain tandem-structured palletizing robots need to be installed at the joints, resulting in problems such as heavy robot arm weight, poor rigidity, large inerti...
