Embodiment
As depicted in figs. 1 and 2, this full-automatic three-dimensional precision positioning campaign injector is made up of Y-axis motion assembly, X-axis motion assembly, Z axle motion assembly, pallet.Y-axis motion assembly is made up of Y-axis moving base 4, y-axis motor 5, Y-axis leading screw 6, Y-axis left rail 7, Y-axis left rail slide block 8, the right guide rail 15 of Y-axis, the right guide rail slide block 12 of Y-axis, Y-axis nut 9, Y-axis photoelectric sensor 14, Y-axis photoelectric sensor catch 13.X-axis motion assembly is made up of X-axis moving base 3 and corresponding motor, leading screw, guide rail, guide rail slide block, X-axis photoelectric sensor 17, X-axis photoelectric sensor catch 16.Z axle motion assembly is made up of Z axle moving base 2 and corresponding motor, leading screw, guide rail, guide rail slide block, Z axis photoelectric sensor 10, Z axis photoelectric sensor catch 19.
The motion assembly all adopts the Chinese character pin-shaped independently moving cell that is combined to form, and Y-axis motion assembly forms Chinese character pin-shaped by Y-axis leading screw 6, Y-axis left rail 7, the right guide rail 15 of Y-axis.Y-axis motor 5 is drive motor, and y-axis motor 5 drives Y-axis leading screw 6 and rotates, and Y-axis leading screw 6 drives Y-axis nut 9 rectilinear motions, and the right guide rail 15 of the right guide rail slide block 12 of Y-axis left rail slide block 8 and Y-axis left rail 7 and Y-axis and Y-axis is determined Y-axis direction of motion.Y-axis machinery anticollision boss 18 is when preventing that Y-axis motion assembly from running to end, and Y-axis nut 9 collision Y-axis moving bases 4 prevent that Y-axis nut 9 is damaged because of collision.Y-axis photoelectric sensor 14 and Y-axis photoelectric sensor catch 13 are determined Y-axis motion initial point, and X-axis photoelectric sensor 17 and X-axis photoelectric sensor catch 16 are determined X-axis motion initial point, and Z axis photoelectric sensor 10 and Z axis photoelectric sensor catch 19 are determined Z axle motion initial point.
The calibration point 11 of full-automatic three-dimensional precision positioning campaign injector is a conical round platform at pallet 1 upper surface.After full-automatic three-dimensional precision positioning campaign injector assembles, in order in instrument, to determine the locus of pallet, need do the position correction of full-automatic three-dimensional precision positioning campaign injector.Determine the location point M of a known coordinate in instrument internal, carry out the space three-dimensional motion by control circuit operation pallet 1, make calibration point 11 aligned position point M.When calibration point 11 aligned position point M, just determined the locus of pallet in instrument internal, thereby determined on the pallet sample in the locus of instrument internal, thereby reached the purpose of accurate sample introduction.
Further specify the method for operation of this full-automatic three-dimensional precision positioning campaign injector below in conjunction with accompanying drawing.Define X, Y, Z direction that three directions shown in Figure 1 are full-automatic three-dimensional precision positioning campaign injector.
Be defined as follows the motion title:
Advance and retreat: along the rectilinear motion of Y-axis, be called along moving of Y-axis forward and advance, retreat otherwise be called.
Sidesway: along the rectilinear motion of X-axis, be called along moving of X-axis forward and move to right, move to left otherwise be called.
Lifting: along the rectilinear motion of z axle, be called rising along moving of z axle forward, otherwise be called decline.
Full-automatic three-dimensional precision positioning campaign injector is determined Y-axis motion initial point by Y-axis photoelectric sensor 14 and Y-axis photoelectric sensor catch 13, X-axis photoelectric sensor 17 and X-axis photoelectric sensor catch 16 are determined X-axis motion initial point, and Z axis photoelectric sensor 10 and Z axis photoelectric sensor catch 19 are determined Z axle motion initial point.According to the needs of current task, to move smoothly according to certain logic, the method for operation is divided into two stages:
(1), makes zero the stage.Full-automatic three-dimensional precision positioning campaign injector is after starting working, full-automatic three-dimensional precision positioning campaign injector at first moves to the position of three photoelectric sensors, be the zero-bit of motion control space coordinates, set up the coordinate at zero point of full-automatic three-dimensional precision positioning campaign injector pallet here.Motion process is as follows: at first Z axle motion assembly motion, pallet 1 descends, when making Z axis photoelectric sensor 10, Z axis photoelectric sensor catch 19 produces induction, Z axis photoelectric sensor 10 sends signal, Z axle motion assembly is slightly adjusted back, make Z axis photoelectric sensor catch 19 leave the slit of Z axis photoelectric sensor 10, avoid Z axis photoelectric sensor 10 to work all the time, the stop motion of Z axle.X-axis motion assembly moves to left then, makes pallet 1 move to the left side in space, produces induction when X-axis photoelectric sensor catch 16 makes X-axis photoelectric sensor 17, and X-axis photoelectric sensor 17 sends signal, and X-axis motion assembly is slightly adjusted back, the X-axis stop motion.At last, Y-axis motion assembly retreats, and makes pallet 1 move to the space outerpace position, produces induction when Y-axis photoelectric sensor catch 13 makes Y-axis photoelectric sensor 14, and Y-axis photoelectric sensor 14 sends signal, and Y-axis motion assembly is slightly adjusted back, the Y-axis stop motion; The stage of making zero finishes.
Position when full-automatic three-dimensional precision positioning campaign injector finished with the stage of making zero is as initial position, set up fixing coordinate system for carrying out later motion, when needs move to the target location, only need calculate the three dimensions distance that arrives destination locations from initial position, just can assign instruction to motor, make tray motion arrive destination locations.
Above X, Y, three directions of Z are moved independent mutually, and namely in the time of a direction setting in motion, other direction all keeps not motion state.
(2), working stage.After Radix Angelicae Sinensis zeroth order section finished, full-automatic three-dimensional precision positioning campaign injector entered the life's work stage.Because full-automatic three-dimensional precision positioning campaign injector is when making zero in the space, determined the locus of pallet 1, so full-automatic three-dimensional precision positioning campaign injector only needs host computer to provide movement instruction, just can be according to predetermined motion path planning motion, motion process is as follows: according to the needs of current task, pallet 1 need run to a certain position in space, full-automatic three-dimensional precision positioning campaign injector passes through space coordinate conversion, calculate full-automatic three-dimensional precision positioning campaign injector and reach the distance that this position needs from initial point, to the instruction that motor sends operating index, move smoothly according to certain logic.
The above embodiment only is the preferred embodiments of the present invention; the invention is not restricted to above-described embodiment; for persons skilled in the art; the any apparent change of under the prerequisite that does not deviate from the principle of the invention it being done all belongs to the protection domain of design of the present invention and claims.
