Description

Y-axis suspension mechanism and manipulator with stable movement in y-axis direction

Technical Field

A y-axis suspension mechanism and a manipulator with stable movement in the y-axis direction belong to the technical field of automatic equipment.

Background

A robot refers to an automatic operating device that mimics certain functions of a human hand and arm for grasping, handling objects or operating tools in a fixed procedure. The manipulator is the earliest industrial robot, and is also the earliest modern robot, and the manipulator replaces heavy labor of people to realize mechanization and automation of production, can operate under harmful environment to protect personal safety, and is widely applied to departments of mechanical manufacture, metallurgy, electronics, light power, atomic energy and the like.

In the ceramic tile production industry, the manipulator is mainly used for transferring ceramic tiles and stacking ceramic tiles, the conventional manipulator can generally complete movement of an x axis, a y axis and a z axis, the x axis and the y axis respectively refer to movement in the horizontal longitudinal direction and the horizontal transverse direction, and the z axis refers to movement in the vertical direction, so that the ceramic tiles are transferred or stacked in a three-dimensional space. When the existing manipulator is used for transferring or stacking ceramic tiles, the following problems exist:

1. the attitude of the ceramic tile cannot be changed, and the ceramic tile can be transported only according to the original attitude of the ceramic tile, so that the ceramic tile can be stacked only in the same mode after being transported, the flexibility is poor, the requirement on the stacking environment is high, and the ceramic tile stacking device is inconvenient to use;

2. The movement of the manipulator along the x-axis, the y-axis and the z-axis can only be operated at a constant speed, so that the operation speed of the manipulator is low in order to ensure that the grabbed ceramic tiles cannot be damaged in the transferring process, and the working efficiency of the manipulator is seriously influenced;

3. when the manipulator moves along the z axis, the z axis upright post can drive the grabbed tiles to lift, and the difference of the weight of the z axis upright post during each lifting can occur due to the different quantity of the grabbed tiles, so that on one hand, the manipulator can vibrate during working, and the problem of collision caused by incapability of accurately controlling the moving speed can also occur;

4. the power device of the existing manipulator is usually a motor, the motor is usually fixed on a frame, and when the walking distance of the manipulator is too large, especially when the walking distance is far away from the motor, the problem of insufficient power can occur due to the too large transmission distance, and the running speed is also unstable;

5. when stacking the ceramic tile, in order to facilitate subsequent transportation or loading of the ceramic tile, a pallet is usually required to be placed, so that subsequent operation is facilitated, and damage to the ceramic tile can be avoided. When the existing manipulator is used for stacking, the pallet needs to be placed manually. Because the manipulator needs to cooperate with the ceramic tile production line, so in daily production process, the manipulator can not shut down, and this just needs the workman to place the pallet in manipulator working process, has the potential safety hazard. In addition, the existing manipulator has higher requirements on the position of the pallet, and the pallet is required to be accurately placed according to the working position of the manipulator when being placed, so that the pallet is inconvenient to use.
