Take the second golden finger interface of the first golden finger interface D1 and pinboard D2 of product D1 to be measured described in motion process each time
Relative motion distance between D20 calculates in motion process each time according to preset number of steps and relative motion distance
Motion-scaling factor.
For example, for rotational motion mechanism 23, before each movement, control unit 4 by optical image unit 3 obtain to
The misalignment angle between the second golden finger interface D20 of the first golden finger interface D10 and pinboard D2 of product D1 is surveyed, θ is denoted as
(1)；Control rotational motion mechanism 23 rotates certain step-length N1 (such as 1000 step-lengths), completes a motion process, leads to again
The misalignment angle between the acquisition of optical image unit 3 first golden finger interface D10 and the second golden finger interface D20 is crossed, θ is denoted as
(2), the motion-scaling factor P11 for obtaining this motion process is expressed as P11={ θ (1)-θ (2) }/N1.It is iteratively repeated above-mentioned
Process, obtain each motion process motion-scaling factor P11, P12 ..., P1n, calculate P11 to P1n average value (indicate
For the corresponding rotational angle of unit moving step sizes), to obtain the calibrated moving step sizes of rotational motion mechanism 23.
For example, for X to movement mechanism 21, before each movement, control unit 4 by optical image unit 3 obtain to
The X between the second golden finger interface D20 of the first golden finger interface D10 and pinboard D2 of product D1 is surveyed to offset distance, is remembered
For x1；The step-length N2 (such as 1000 step-lengths) that control X moves along a straight line certain to movement mechanism 21, completes a motion process, then
It is secondary that X between first golden finger interface D10 and the second golden finger interface D20 is obtained to offset distance by optical image unit 3,
It is denoted as x2, obtains the motion-scaling factor P21 of this motion process, is expressed as P21={ x2-x1 }/N2.It is iteratively repeated above-mentioned mistake
Journey, obtain each motion process motion-scaling factor P21, P22 ..., P2n, calculate P21 to P2n average value (be expressed as
The corresponding linear motion distance of unit motion step-length), to obtain calibrated moving step sizes of the X to movement mechanism 21.Together
Reason, can be obtained the calibrated moving step sizes of Y-direction motion 22, is not discussed here.
Step S113, by the calibrated moving step sizes write control unit 4 of each movement mechanism, i.e., by calibrated fortune
Dynamic step-length, which is stored in control unit 4, to be realized and calls at any time.
Step S121, the elevating mechanism 12 that control unit 4 controls in product aligning unit 1 are repeatedly moved back and forth.
Step S122 obtains the product D1 to be measured in motion process each time of elevating mechanism 12 by optical image unit 3
The first golden finger interface D10 and D2 pinboard the second golden finger interface D20 between relative position deviation, the relative position
Deviation includes horizontal X to position deviation, horizontal Y-direction position deviation and horizontally rotates position deviation.
Horizontal X to position deviation, horizontal Y-direction position deviation and is horizontally rotated position deviation and is respectively written by step S123
