The fitting of constraint side complete the Y-axis positioning of square objects to be positioned, wherein the first positioning pressure infeed mean 31 can be
It two or multiple, specifically can be according to the property settings of square objects 4 to be positioned, the second positioning pressure infeed mean
32 can be for one or multiple, specifically can be according to the property settings of square objects 4 to be positioned, rectangular object to be positioned
The first side 41 of body 4 and the second side 42 of square objects to be positioned are two adjacent sides.
The manipulator, for place square objects 4 to be positioned and for by least two first positioning pressure into
To component 31 and the movement of at least one described second positioning pressure infeed mean 32 and it is fixed on the upper of square objects 4 to be positioned
Side.
Specifically, as shown in Figures 2 to 4, the working principle of square objects positioning mechanism are as follows:
When positioning, near the X axis of positioning table 1, two the first positioning pressure infeed means 31 are in side to be positioned
The top of shape object 4 applies two appropriately sized pressure, and the pressure spot of two pressure is indicated with F1, F2 respectively, so that above-mentioned two
A pressure spot stiction f1, f2 corresponding with 4 upper surface of square objects generation to be positioned；4 lower surface of square objects to be positioned
Two quiet frictional force f1_1, f2_1 of corresponding generation between positioning table 1；And guarantee f1 ≈ f2, f1 > f1_1, f2 > f2_
1.The position that two pressure spots of square objects 4 to be positioned will be applied to is mobile to X-direction relative to positioning table 1, this
When, due to f1 ≈ f2, f1 > f1_1, f2 > f2_1；Square objects 4 to be positioned overcome f1_1 in f1, f2, and the active force after f2_1 is led

Obligatory point 11, the second obligatory point 12 are successively overlapped after being adjacent to, and 4 stress condition of square objects to be positioned changes, the first constraint
The 11, second obligatory point 12 of point generates reaction force F1_1, F2_1 in the position pressure spot F1, F2 to square objects to be positioned so that
Square objects 4 to be positioned are changed into opposing stationary, frictional force f1 with positioning table 1 from opposite sliding, and f2 is less than reaction force
F1_1, F2_1, pressure spot occur to slide relatively with square objects 4 to be positioned, and X axis positioning is completed；Then, it will be applied to undetermined
The position of two pressure spots F1, F2 of position square objects 4 stop relative to positioning table to X-direction movement, and will apply
Cancel to two pressure spot F1 of square objects, the position of F2 is relative to positioning table 1 to Y direction movement so that rectangular object
The second side of body is bonded the third obligatory point 13 in Y-axis completely, the positioning of Y direction is similarly completed, so that it is determined that rectangular object
The accurate location of body is also possible to be greater than two specifically, mobile pressure spot is not necessarily two when mobile to X-direction

On square objects 4 to be positioned, it is ensured that square objects 4 to be positioned and the first obligatory point 11, the second obligatory point 12 are adjacent to
Afterwards, the friction between pressure spot and square objects to be positioned is changed into sliding friction, and square objects to be positioned 4 from quiet frictional force
Pressure spot and the first obligatory point 11 are not led to because frictional force is excessive, the part between the second obligatory point 12 generates Curved
Become.When mobile to Y direction, the quantity of mobile pressure spot be may be greater than equal to one, such as increase by one second positioning
Forced feed component 32 applies appropriately sized pressure F3, and these pressure spots in the top of square objects 4 to be positioned
Position must all be the third obligatory point 13 as close to Y-axis, and be located on square objects 4 to be positioned, it is ensured that
Positioning square objects 4 and after third obligatory point 13 is adjacent to, friction between pressure spot and square objects to be positioned is from quiet frictional force
It is changed into sliding friction, and square objects to be positioned do not cause between pressure spot and third obligatory point 13 because frictional force is excessive
Part generate Bending Deformation.
