The mounting head 110 includes a plurality of mounting heads 110 mounted on a circumference and a rotary head 112 that stops the positioning of the mounting head 110 at a predetermined position (stations ST1 to ST12) by rotating the index by indexing. (See, for example, JP-A-2001-62767 (FIGS. 1 to 3)).
[0003]
The rotary head 112 repeatedly rotates the mounting head 110 by index rotation between a component supply position ST1 where components are supplied from the component supply unit 101 and a component mounting position ST7 where the substrate W is positioned by the XY table 102. The mounting head 110 is moved up and down at a component supply position ST1 and a component mounting position ST7 while controlling the mounting head 110 to a required height in accordance with the moving position.
[0004]
Next, the mounting head 110 will be described. 12 is a front view of the mounting head 110, FIG. 13 is a cross-sectional view taken along line CC of FIG. 12, and FIG. 14 is a cross-sectional view taken along line DD of FIG.
As shown in FIG. 13, the mounting head 110 is mounted on a rotary head 112 via a guide 114 so as to be slidable in the vertical direction. At a predetermined position of the guide portion 114, a cam follower 118 that engages with the lifting / lowering groove cam 116 is provided. When the rotary head 112 rotates, the mounting head 110 is controlled to a required height according to the rotational position. It has become so.
[0005]
The mounting head 110 includes a housing 120 that is vertically slidably coupled to a rotary head 112 via a guide portion 114, and a motor portion 122 that is fixed to an upper end portion of the housing 120 with the rotation axis oriented in a vertical direction. A reduction gear 124 for reducing the rotation of the motor part 122, a rod part 126 connected to an output shaft of the reduction gear 124 and rotating around a vertical rotation axis, and disposed between the housing 120 and the rod part 126. Bearings 128 and 129 rotatably supporting the rod portion 126, a plurality of suction nozzle portions 130 respectively mounted on the rod portion 126 so as to be able to move up and down, and the suction nozzle portion 130 arranged on the outer periphery of the rod portion 126 to connect the rod portion 126 to the rod portion It is necessary to move the cylindrical cam 140 up and down according to the rotation of the 126 and the cylindrical cam 140 so as not to rotate together with the rod 126. And a stopper mechanism 150 to lock in response.
[0006]
The suction nozzle portion 130 is vertically slidably housed in a mounting groove 127 formed in the rod portion 126, and protrudes above the suction nozzle body 131 in a direction perpendicular to the longitudinal direction of the suction nozzle body 131. And a single roller 133 rotatably mounted on the outer periphery of the support pin 132. The upper end of the suction nozzle body 131 and the upper end of the mounting groove 127 are provided. And the whole is urged downward by a spring 139 disposed therebetween.
[0007]
As shown in FIG. 14, the suction nozzle sections 130 are arranged at a predetermined pitch on a circumference concentric with the rotation axis of the rod section 126, and each suction nozzle body 131 has its own cross section and a mounting Since the cross section of the groove 127 is formed as a rectangular cross section, the groove 127 is held by the rod portion 126 so as not to rotate. Further, as described above, one roller 133 is rotatably mounted on the support pin 132, and this roller 133 is in contact with the cam surface 141 at the upper end of the cylindrical cam portion 140. The vertical position of the suction nozzle portion 130 is regulated along the trajectory of the cam surface 141 when the roller 133 is pressed onto the cam surface 141 by a spring 139.
[0008]
The stopper mechanism 150 is provided between the cylindrical cam 140 and the housing 120. The stopper mechanism 150 is provided slidably in a stopper hole 142 provided in the body surface of the cylindrical cam portion 140 and a hole formed in the housing 120 so as to be capable of engaging and disengaging from the stopper hole 142 of the cylindrical cam portion 140.

[0009]
In the mounting head 110, when the motor 122 is rotated with the stopper pin 152 engaged with the stopper hole 142 of the cylindrical cam 140, the rod 126 rotates with respect to the cylindrical cam 140. Therefore, according to the trajectory of the cam surface 141, the height of each of the plurality of suction nozzle portions 130 held by the rod portion 126 can be regulated. Therefore, the suction nozzle portion 130 held at the lowest position of the plurality of suction nozzle portions 130 can be controlled. It can be selected as one used for component mounting.
[0010]
On the other hand, when the motor portion 122 is rotated in a state where the stopper pin 152 is detached from the stopper hole 142, the cylindrical cam portion 140 rotates together with the rod portion 126. Therefore, it is possible to correct only the rotational position of the suction nozzle unit 130 while keeping the height of the suction nozzle unit 130 unchanged. In other words, even when the rotary head 112 is rotating, the operation of positioning the suction nozzle unit 130 in the rotation direction and the operation of selecting the suction nozzle unit 130 by positioning in the vertical direction are switched by operating the stopper mechanism 150.

However, when the suction nozzle main body 131 and the mounting groove 127 are formed in a square cross section, processing is difficult, and when using one with low processing accuracy, the sliding resistance increases, causing malfunction and premature wear may occur. In addition, there is a problem that the processing cost is increased in order to secure processing accuracy.
[0013]
As shown in FIG. 15, a vertical guide groove 160 is formed in the rod portion 126 inside the cylindrical cam portion 140, and the roller 133 is inserted through the guide groove 160, thereby forming the guide groove 160. It is conceivable to regulate the position of the roller 133 on the groove side surface, thereby suppressing the rotation of the suction nozzle main body 131. However, in this case, the roller 133 moves in two directions, that is, a vertical direction H1 along the guide groove 160 and a circumferential direction H2 along the cam surface 141 of the cylindrical cam portion 140. There is a risk that the roller 133, the cam surface 141, the groove side surface of the guide groove 160, and the like will be worn out, resulting in the occurrence of abrasion due to abrasion.
[0014]
On the other hand, as shown in FIG. 16, there is a mechanism for selecting a nozzle 170 by providing a rotation driving unit at a position distant from the suction nozzle unit. In this mechanism, when selecting the nozzle 170, a gear 171 is used. In order to engage and disengage the engagement lever 172 and rotate the gear 171 by the rotation drive unit at a position away from the suction nozzle unit to select the nozzle 170, the configuration of the external rotation drive unit becomes large, It takes a long time to stop and has a problem that hinders speeding up.

[0029]
As shown in FIG. 5, the suction nozzle sections 30 are arranged at a predetermined pitch on a circumference concentric with the rotation axis of the rod section 26. Here, the cross section of each suction nozzle main body 31 and the mounting groove 27 has a circular cross-sectional shape that is easy to process. Since the rotation of the suction nozzle main body 31 cannot be regulated in this state, a guide groove 35 is formed in the rod portion 26 along the vertical direction for restricting the rotation of the suction nozzle main body 31. In addition, of the two rollers 33, 34, the inner first roller 33 is disposed so as to contact the groove side surface of the guide groove 35.
