Efficient and precise manipulator

Abstract

The invention relates to the field of mechanical transmission equipment, in particular to an efficient and precise manipulator comprising a main plate, a guide rail assembly, a horizontal support and a synchronous transmission assembly. A first cam transmission assembly is arranged on the left side of the main plate, a second cam transmission assembly is arranged on the right side of the main plate, the first cam transmission assembly is composed of a horizontal cam and a first rocker, the second cam transmission assembly is composed of a vertical cam and a second rocker, and the horizontal cam and the vertical cam are jointly driven by the synchronous transmission assembly to synchronously rotate. The whole manipulator can be of a small flat structure, the occupied space is quite small, the first cam transmission assembly and the second cam transmission assembly are combined to drive the horizontal support to move in an arc track, and the horizontal support can move to any point precisely through the arc track, so that overall stable operation of the manipulator is ensured, shock is avoided, and assembling stability is guaranteed; and the precision is high by adopting the cam transmission structure, and the manipulator is especially suitable for automatic machining or assembling with the high precision requirement.

Description

technical field [0001] The invention relates to the field of mechanical transmission equipment, in particular to cam transmission technology, and in particular to an efficient and precise manipulator. Background technique [0002] In automatic assembly operations, the manipulator is often required to perform the simplest action: grab the workpiece at a certain position, and then put it down at another position to realize feeding, processing, assembly and other actions. In order to realize this work, there are the following two structures in the prior art to complete this action: 1) The grasping and placing manipulator driven by air pressure, this kind of structure is simple, flexible and convenient to install, low in purchase cost, and can only realize simple grasping And moving action, the grasping force driven by air pressure is small, and it can only move in a straight line when moving. Slow; 2) The motor drives the grabbing and placing manipulator. This structure has a ...

In order to realize this work, there are the following two structures in the prior art to complete this action: 1) The grasping and placing manipulator driven by air pressure, this kind of structure is simple, flexible and convenient to install, low in purchase cost, and can only realize simple grasping And moving action, the grasping force driven by air pressure is small, and it can only move in a straight line when moving. Slow; 2) The motor drives the grabbing and placing manipulator. This structure has a large grabbing force, is easy to install, has high flexibility, and can be docked at multiple points. If the assembly system needs to be changed or redesigned, simply reprogram it. However, motor-driven manipulators need to be equipped with complex electrical control systems. If such manipulators are used to complete relatively simple repetitive tasks, the cost will be high. The cooperation of multiple motors can achieve multi-axis transmission, and the movement speed is relatively fast. However, when The faster the movement speed, the greater the error, which affects the movement error. It is difficult to accurately control the acceleration and speed of the manipulator movement, especially when it stops, the action is blunt and the impact vibration is large. Moreover, this structure can only move along a straight line. Need When positioning and moving, only horizontal and vertical linear movements can be staggered. In addition, this structure has a large volume and requires a combination of multiple sets of mechanical arms. In addition to the driving structure, the overall volume is large
