Description

Technical Field

[0001] The utility model relates to the field of industrial automation, in particular to a lifting mechanism of a linear manipulator. Background Art

[0002] A linear manipulator is a common device in industrial robots or automation systems. It is used to perform precise movements and operations on a straight path. It can move and position on a specified straight path with extremely high precision. In an automated production line, a linear manipulator can replace manual work for monotonous and repetitive tasks, improving production efficiency and consistency. They can quickly perform the same operation and reduce variables and errors in the production process. In certain dangerous environments or tasks that require high safety control, the use of linear manipulators can reduce the risk of manual operation and improve the safety of the working environment. Existing linear manipulators can basically meet the use requirements of production, but the movement of linear manipulators is limited to their fixed linear tracks, so there are limitations when it is necessary to operate in the vertical direction or access different height positions. If the height of the working area is uneven or it is necessary to frequently access parts or assemblies at different heights, the linear manipulator may require additional equipment or adjustments to achieve the required operating height. In applications where the working height needs to be changed frequently or where different height positions need to be accessed, the efficiency of the linear manipulator may be limited, thereby affecting the space utilization and work efficiency of the mechanism; therefore, it is necessary to design a lifting mechanism for a linear manipulator.
