Background

A manipulator refers to an automatic operating device that can imitate some functions of a human hand and arm to grab, carry objects or operate tools according to a fixed procedure. The manipulator is the earliest industrial robot and the earliest modern robot, replaces heavy labor of people to realize mechanization and automation of production, can operate in harmful environment to protect personal safety, and is widely applied to mechanical manufacturing, metallurgy, electronics, light industry, atomic energy and other departments.

In the ceramic tile production industry, the main effect of manipulator is the transportation of ceramic tile and the pile up neatly of ceramic tile, and the removal of x axle, y axle and z axle can be accomplished usually to current manipulator, and x axle, y axle indicate respectively at horizontal vertical and horizontal removal, and the z axle indicates the removal in vertical direction to the realization is transported or is piled up neatly the ceramic tile in three-dimensional space. The existing manipulator has the following problems in transferring or stacking ceramic tiles:

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

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, and in order to ensure that the captured ceramic tiles cannot be damaged in the transferring process, the operation speed of the manipulator is required to be low, so that 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 captured tiles to lift, and because the number of the captured tiles is different every time, the weight of the z axis upright post during lifting is different every time, so that on one hand, the manipulator can vibrate during working, and on the other hand, the problem of collision caused by the fact that the moving speed cannot be accurately controlled can also occur;

4. the power device of the existing manipulator is usually a motor, and the motor is usually fixed on a rack, so that when the manipulator travels too far, especially when the manipulator is far away from the motor, the problem of insufficient power can occur due to too large transmission distance, and the operation speed is also very unstable;

5. when pile up neatly to the ceramic tile, for the follow-up transportation or the loading of convenient ceramic tile, the pallet need be placed usually, has both made things convenient for subsequent operation, can avoid again causing the damage to the ceramic tile. When the existing mechanical arm is used for stacking, the pallet needs to be manually placed. Because the manipulator need with the cooperation of ceramic tile production line, consequently in daily production process, the manipulator can not shut down, and this just needs the workman to place the pallet in the manipulator working process, has the potential safety hazard. And the requirement of current manipulator to the position of pallet is than higher, need place the pallet according to the position accuracy of manipulator work when placing, uses very inconveniently.
