Effect of the present invention and benefit are:
(1) relative position between many group Suction cup assemblies can be regulated; Adapt to the carrying operation of different size solar module; And organize Suction cup assembly more and can guarantee that solar module is evenly stressed in the adsorption process, can accomplish the loading and unloading of solar battery sheet safely and reliably.
(2) two groups of perpendicular movement unit of symmetry installation can guarantee perpendicular movement unit stress equalization in handling process, avoid producing moment of flexure.
(3) have simple in structure, working space is big, accuracy of positioning is high, reliable characteristics such as steadily.
(4) reduced labour intensity, improved labor efficiency, the high fragment rate of having avoided a dead lift to cause.

The specific embodiment
Be described in detail the specific embodiment of the present invention below in conjunction with technical scheme and accompanying drawing.
Solar module loading and unloading conveying robot of the present invention is made up of manipulator mechanism I, horizontal motion unit II, two groups of perpendicular movement unit III, pallet elevator structure IV and fuselage V; Manipulator mechanism adopts aluminium alloy extrusions frame combination structure; Utilize vacuum cup as applying the Clamping force main body, relative position can be regulated between each sucker.The horizontal motion unit is made horizontal reciprocating movement to servomotor through synchronous cog belt speed reduction gearing drives mechanical hand mechanism by X.The perpendicular movement unit passes through the dipping and heaving of ball guide screw nat drives mechanical hand mechanism by Z to servomotor.Finally accomplish the operation of feeding and discharging of solar module jointly by pallet elevator structure and manipulator mechanism.
Concrete course of action is following:
The motion of pallet elevator structure: pallet is placed on the tray supporter 21; Pallet positioning baffle 23 is confirmed pallet position on tray supporter 21; After pallet is placed; To the gas of four cylinders, 22 feeding certain pressures, four cylinders 22 will drive tray supporter 21 and upwards rise synchronously, and the pallet guardrail 20 of both sides is used for preventing that the solar module sideslip damages in the process of going up and down.
X links to each other with first slide 7 through synchronous toothed belt wheel speed reduction gearing to servomotor 13 to motion: X; Driving first slide 7 through synchronous cog belt 8 slides on first line slideway 9; First slide 7 drives robot movement through the perpendicular movement unit in the horizontal motion unit; Thereby the X that realizes conveying robot is to motion, when X when motion runs into left-limit switch 6 or limit on the right-right-hand limit switch 11, the conveying robot stop motion; When left-limit switch 6 or 11 inefficacies of limit on the right-right-hand limit switch, left limit block 5 will be forced the conveying robot stop motion with right limit block 12.
Z is to motion: by the realization that is synchronized with the movement of two groups of perpendicular movement unit; Z makes through ball guide screw nat 16 between second line slideway 14 and second slide 15 to servomotor 17 and produces relative motion; Thereby through two Z to servomotor 17 be synchronized with the movement realize conveying robot Z to motion; When the downward location of conveying robot fails correctly to accomplish, destroy solar module in order to prevent manipulator mechanism, a level sensor 4 is installed below manipulator mechanism; When level sensor 4 triggers; Force the conveying robot stop motion immediately, wherein ball guide screw nat 16 has self-lock ability, prevents under the solar module action of gravity, to occur counter-rotating decline phenomenon.
The solar module sucking action is realized: the automatic operational process of manipulator relies on software to realize its accurate location, and when accomplished the manipulator mechanism location, X and Z stopped to motion, organize Suction cup assembly 2 more and adsorb solar module simultaneously.On vacuum cup source of the gas general line, adorned a vacuum manometer; Be used for monitoring real-time force value; Judge whether current pressure satisfies when the needed pressure of absorption solar module perhaps discharges whether reach required value, thus the safety of operating in assurance absorption and the dispose procedure.When the solar module specification changes, through on the sucker positioning supports plate between the groove adjustment Suction cup assembly 2 relative position can regulate, guarantee to draw safely and reliably solar module.
Solar module loading and unloading conveying robot of the present invention adopts programmable controller and touch-screen to jointly control mode, the preferred site master mode.Control system is made up of three levels, that is: man-machine interaction layer (touch-screen), motion control layer (programmable controller) and servocontrol layer.Man-machine interaction layer (touch-screen) is used to carry out mission planning and parameter setting, forms handling machinery hands movement requisite space parameter, comprises parameters such as starting point, terminal point, and the work of the real-time monitoring aspect of responsible control system.Motion control layer (programmable controller) is the function block of programmable controller utilization " MAP SERV " instruction database, to actuator outbound course and position pulse signal, realizes the motion control of manipulator according to the program of setting and parameter thereof.The servocontrol layer as given, as feedback, is realized position servo control with the servomotor actual position that measures with the position signal of motion control layer.
