Description

A kind of y-axis drive mechanism and can be along the mechanical hand of y-axis speed change movement

Technical field

A kind of y-axis drive mechanism and technical field of automation equipment can be belonged to along the mechanical hand of y-axis speed change movement.

Background technology

Mechanical hand is some functions of referring to imitate staff and arm, in order to capture, to carry object or behaviour by fixed routine Make the automatic pilot of instrument.Mechanical hand is the earliest industrial robot occurring, and is also the earliest modern machines people occurring, machine Tool handss replace the heavy labor of people to realize the mechanization and the automatization that produce, can operate to protect person peace under hostile environment Entirely, mechanical hand is widely used in the departments such as machine-building, metallurgy, electronics, light work(and atomic energy.

In ceramic tile production sector, mechanical hand Main Function is the transhipment of ceramic tile and the piling of ceramic tile, existing manipulator The movement of x-axis, y-axis and z-axis usually can be completed, x-axis, y-axis refer to the movement in level longitudinal direction and horizontal cross, z respectively Axle refers to the movement in vertical direction, thus realizing ceramic tile being transported through or piling in three dimensions.Existing machinery Handss are being transported through to ceramic tile or during piling, there are the following problems：

1st, the attitude of ceramic tile cannot be changed, can only be transported according to the original attitude of ceramic tile, therefore after transhipment, ceramic tile be entered During row piling, it is merely able to carry out piling according to same mode to ceramic tile, motility is poor, the requirement to the environment of piling is relatively Height, in-convenience in use；
