Put the original position (reference position) that Lo is scanning camera 81, in this example, be the position of the left end of head unit 60.In addition,
In this specification, from the left side of Figure 11 successively to each mounting head 73 reference numerals, " Lx1 " represents from origin position Lo to first
The distance of mounting head 73-1, " Lx2 " represents the distance of mounting head 73-2 from origin position Lo to second.
Hereinafter, pass through the correction process that control unit 210 carries out and illustrate to changing along with scanning element.Here,
Illustrated in case of scanning element 80 is replaced by new scanning element 80.
Control unit 210 is carried out to position reference component by existing scanning camera 81 before scanning element replacement operation
77A carries out the process of image recognition.I.e., first, origin position Lo shown in Figure 11 for the existing scanning camera 81 is made to move.
And, control unit 210 enters to exercise scanning camera 81 and moves in X direction from origin position Lo and identify position reference portion
The process of part 77A, and be handled as follows：Obtained from origin position Lo to position reference portion based on the recognition result obtaining
The distance " Lm0 " of the X-direction of part 77A, and by this data storage in storage part 220 (S10, the S20 shown in Figure 13).
Afterwards, by operator, enter the operation being about to that existing scanning element 80 is changed with new scanning element 80
(S30).And, at the end of the replacement operation of scanning element 80, control unit 210 and the control that existing scanning camera 81 is carried out
System similarly carries out using the new scanning camera 81 after changing, position reference component 77A is carried out with the process of image recognition.That is,
First, origin position Lo shown in Figure 12 for the scanning camera 81 after replacing is made to move.And, enter to exercise the scanning phase after changing
Machine 81 moves in X direction from origin position Lo and identifies the process of position reference part 77A, is obtained from former based on recognition result
The distance " Lm1 " (S40, the S50 shown in Figure 13) of the point X-direction to position reference part 77A for the position Lo.
Afterwards, control unit 210 compare the distance " Lm0 " away from position reference part 77A before replacing with change after away from position
Put the distance " Lm1 " of reference component 77A, the variable quantity α (S60) of computed range.
α=Lm1-Lm0 (1) formula
Additionally, the symbol of " α " is " just " in Lm1 ＞ Lm0, in Lm1 ＜ Lm0 it is " bearing ".
And, control unit 210 carries out following process：Corrected from scanning camera 81 based on the variable quantity α calculating
Origin position Lo to each mounting head 73 in the X direction apart from Lx.Specifically, as shown in figure 12, will from origin position Lo to
Distance " Lx1 " before changing for the distance of first mounting head 73-1 is corrected to " Lx1+ α ".In addition, similarly will be away from second
The distance of mounting head 73-2 is corrected to " Lx2+ α " from " Lx2 ".And, similarly correct the distance away from remaining mounting head 73
(S70 shown in Figure 13).
And, in the production of printed base plate P, image recognition is being carried out to the electronic component being adsorbed holding by mounting head 73
In the case of, control unit 210 identifies the position of the X-direction of each mounting head 73 based on the distance after correction, shoots adsorbed guarantor
It is held in the electronic component of each mounting head 73.That is, control unit 210 makes scanning camera 81 move " Lx1+ α " from origin position Lo
Moment carry out the shooting of the adsorbed electronic component being held in first mounting head 73-1.In addition, moving from origin position Lo
Move the moment of " Lx2+ α ", carried out the shooting of the adsorbed electronic component being held in second mounting head 73-2, similarly carry out
The shooting of remaining electronic component.
From the foregoing, it will be observed that after the replacing of scanning element 80, can by scanning camera 81 and each mounting head 73 in the X direction
Relative position relation remains and changes front identical relation.If describing in detail, when changing scanning element 80, sometimes because of scanning
The error of the installation site with respect to head unit 60 for the unit 80, deviation of components accuracy etc., compared with before replacing, scanning camera 81
Origin position Lo offset in X direction.
When origin position Lo offsets in the X direction, from origin position Lo to each mounting head 73 before Lx with replacing
Compare and change, therefore when using scanning camera 81 identification electronic component, compared with before replacing, the position of electronic component exists
Skew it is identified in X-direction.
With regard to this point, in this surface mounting apparatus 1, it is provided with position reference part 77A in head unit 60.Position reference part
77A is affixed to the constant part in position of head unit 60, even if changing scanning element 80 etc., the position of position reference part 77A
It is also fixing for putting.Therefore, before the replacing in scanning element 80 with change after using scanning camera 81 to position reference section
Part 77A carries out image recognition, compares the distance away from position reference part 77A, and the position thus, it is possible to obtain origin position Lo is inclined
Move (variable quantity α).And, based on the variable quantity α obtaining, correction exists to each mounting head 73 from the origin position Lo of scanning camera 81
In X-direction apart from Lx.Therefore, because can change scanning element after 80s by scanning camera 81 and each mounting head 73 in X side
Relative position relation upwards remains and changes front identical relation, if therefore shooting identical electronic component, can take
Must have the advantages that repeatability is high with identical image before replacing.In addition, according to the recognition result of position reference part 77A, removing
Outside the position of X-direction, it is capable of identify that the position of Y-direction.Thus, it is also possible to according to change scanning element 80 before with change after
Using scanning camera 81, position reference component 77A is carried out with result obtained from image recognition, the Y-direction of detection scanning camera 81
Position side-play amount (variable quantity of the position of Y-direction), it is also possible to correct scan in addition to X-direction is apart from the correction of Lx
The position skew (that is, the position skew of the Y-direction of origin position Lo) of the Y-direction of camera 81.Additionally, the position with regard to Y-direction
Correction, as long as by the Y side of the position correction scanning camera 81 of the Y-direction of the electronic component being identified by scanning camera 81 after replacing
To position side-play amount.
4. effect explanation
Component recognizing camera 17 and scanning camera 81 all shoot the adsorbed electronic component being held in mounting head 73, and purposes is
Identical.But, due to component recognizing camera 17 be fixed, the visual field of therefore camera is larger, have can shoot large-scale
The advantage of electronic component, but need to make the mobile set location to camera of head unit 60, head unit 60 after stick electronic components
Displacement elongated.On the other hand, the visual field of the camera of scanning camera 81 is less, is therefore unsuitable for shooting large-scale electronics unit
Part, but by electronic component can be shot using by the electronic component being adsorbed to the time of movement on printed base plate, therefore
