[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

[0009] 1 shows a component mounter 10. The component mounter 10 is a device for performing a mounting operation of components on a circuit board 12. The component mounter 10 includes an apparatus main body 20, a board transport and holding device 22, a component mounting device 24, imaging devices 26, 28, a component supply device 30, a bulk component supply device 32, and a nozzle changer (see FIG. 3) 34. Examples of the circuit board 12 include a circuit board, a three-dimensional structure board, etc., and examples of the circuit board include a printed wiring board, a printed circuit board, etc.

[0010] The device body 20 is composed of a frame 40 and a beam 42 suspended on the frame 40. The substrate transport and holding device 22 is disposed in the center of the frame 40 in the front-rear direction, and includes a transport device 50 and a clamp device 52. The transport device 50 is a device for transporting the circuit substrate 12, and the clamp device 52 is a device for holding the circuit substrate 12. As a result, the substrate transport and holding device 22 transports the circuit substrate 12 and holds the circuit substrate 12 fixedly at a predetermined position. In the following description, the transport direction of the circuit substrate 12 is referred to as the X direction, the horizontal direction perpendicular to that direction is referred to as the Y direction, and the vertical direction is referred to as the Z direction. In other words, the width direction of the component mounter 10 is the X direction, and the front-rear direction is the Y direction.

[0011] The component mounting device 24 is disposed on the beam 42 and has two work heads 60, 62 and a work head moving device 64. Each of the work heads 60, 62 has a suction nozzle (see FIG. 2) 66, and holds a component by the suction nozzle 66. The work head moving device 64 also has an X-direction moving device 68, a Y-direction moving device 70, and a Z-direction moving device 72. The two work heads 60, 62 are moved integrally to any position on the frame 40 by the X-direction moving device 68 and the Y-direction moving device 70. The work heads 60, 62 are also detachably attached to sliders 74, 76 as shown in FIG. 2, and the sliders 74, 76 are moved individually in the vertical direction by the Z-direction moving device 72. That is, the work heads 60, 62 are moved individually in the vertical direction by the Z-direction moving device 72.

[0012] The imaging device 26 is attached to the slider 74 facing downward, and moves together with the work head 60 in the X, Y, and Z directions. This allows the imaging device 26 to image an arbitrary position on the frame 40. The imaging device 28 is disposed between the base material conveying and holding device 22 and the component supplying device 30 on the frame 40 facing upward, as shown in Fig. 1. This allows the imaging device 28 to image a component held by the suction nozzle 66 of the work heads 60, 62.

[0013] The component supply device 30 is disposed at one end of the frame 40 in the front-rear direction. The component supply device 30 has a tray-type component supply device 78 and a feeder-type component supply device (not shown). The tray-type component supply device 78 is a device that supplies components placed on a tray. The feeder-type component supply device is a device that supplies components by a tape feeder (not shown) or a stick feeder (not shown).

[0014] The bulk component supplying device 32 is disposed at the other end of the frame 40 in the front-rear direction. The bulk component supplying device 32 is a device that aligns a plurality of components that are scattered randomly and supplies the components in the aligned state. In other words, it is a device that aligns a plurality of components in any posture in a predetermined posture and supplies the components in the predetermined posture. Note that components supplied by the component supplying device 30 and the bulk component supplying device 32 include electronic circuit components, solar cell components, power module components, etc. Also, electronic circuit components include components with leads and components without leads, etc.

[0015] Furthermore, the nozzle changer 34 is disposed between the substrate conveying and holding device 22 and the component supply device 30 on the frame 40, and has a nozzle station 80 and a lifting device 82, as shown in Fig. 3. The nozzle station 80 accommodates one or more suction nozzles 66, and a plurality of mounting holes 86 are formed in the upper surface of the nozzle station 80. The suction nozzles 66 can be mounted in each of the plurality of mounting holes 86.

[0016] The lifting device 82 lifts and lowers the nozzle station 80 by driving a rotary air cylinder (see FIG. 4) 88, and includes a guide mechanism 90 and a cam mechanism 92. The guide mechanism 90 includes a pair of ball splines 100 and a mounting table 102. Each of the pair of ball splines 100 includes a spline shaft 106 and a spline nut 108. A spline groove (not shown) is formed on the outer circumferential surface of the spline shaft 106 so as to extend in the axial direction of the spline shaft 106, and a plurality of return balls (not shown) built into the spline nut 108 are fitted into the spline groove of the spline shaft 106. This allows the spline nut 108 to move linearly along the spline groove of the spline shaft 106. The ball spline 100 is disposed on a base 110 of the lifting device 82 in an orientation extending in the vertical direction, and the spline nut 108 is fixed to the base 110. The mounting table 102 has a generally rectangular plate shape and is fixed to the upper ends of the pair of ball splines 100 at two diagonally opposite corners of the mounting table 102 in an orientation extending horizontally. The nozzle station 80 is fixed to the upper surface of the mounting table 102. As a result, the guide mechanism 90 guides the nozzle station 80 in the vertical direction.

[0017] The cam mechanism 92 is composed of an arm 120, a cam follower 122, and a lifting plate 124. The arm 120 is disposed on the side surface of the base 110 so as to be swingable about a shaft 126 extending in the horizontal direction. A cam follower 122 is disposed at the tip of the arm 120, and the cam follower 122 revolves about the shaft 126 as the arm 120 swings. The lifting plate 124 is generally in the shape of a rectangular plate, and the upper end of the lifting plate 124 is fixed to the lower surface of the mounting table 102 with the longitudinal direction of the lifting plate 124 extending in the vertical direction. A long hole 128 extending in the left-right direction is formed at the lower end of the lifting plate 124, and the cam follower 122 fits into the long hole 128.

[0018] The rotary air cylinder 88 is disposed inside the base 110. As shown in FIG. 4, the rotary air cylinder 88 is composed of an air cylinder 130, a rack 132, and a pinion gear 134. The air cylinder 130 is disposed in a posture extending in the left-right direction, and the rack 132 is fixed coaxially to the air cylinder 130 at the tip of the rod 136 of the air cylinder 130. The pinion gear 134 meshes with the rack 132. The shaft 126 of the arm 120 disposed on the side surface of the base 110 extends into the inside of the base 110 and is fixed coaxially to the pinion gear 134. As a result, the rack 132 moves linearly in the left-right direction with the operation of the air cylinder 130, and the pinion gear 134 rotates, thereby rotating the shaft 126. The rotation of the shaft 126 causes the cam mechanism 92 to raise and lower the nozzle station 80.

[0019] In detail, when the air cylinder 130 of the rotary air cylinder 88 is fully contracted, the arm 120 faces vertically downward and the nozzle station 80 is lowered as shown in FIG. 5. At this time, the cam follower 122 fixed to the tip of the arm 120 is located directly below the shaft 126 of the arm 120 and is fitted into the right end of the long hole 128 of the lift plate 124. Then, as the air cylinder 130 extends, the shaft 126 of the arm 120 rotates clockwise, and the arm 120 swings clockwise. At this time, the cam follower 122 fixed to the tip of the arm 120 revolves clockwise and moves toward the upper left, and moves to the left of the shaft 126 of the arm 120 as shown in FIG. 6. In this way, the cam follower 122 moves to the left of the shaft 126 of the arm 120, and reaches the left end inside the long hole 128 of the lift plate 124. At this time, the cam follower 122 fitted in the long hole 128 pushes up the lift plate 124, causing the nozzle station 80 to rise.

[0020] Then, as the air cylinder 130 is further extended, the shaft 126 of the arm 120 rotates clockwise, and the arm 120 swings clockwise. At this time, the cam follower 122 fixed to the tip of the arm 120 further revolves clockwise and moves toward the upper right. Then, when the air cylinder 130 is fully extended, the cam follower 122 moves directly above the shaft 126 of the arm 120 as shown in FIG. 7. In this way, the cam follower 122 moves directly above the shaft 126 of the arm 120, and reaches the right end inside the long hole 128 of the lift plate 124. At this time, the cam follower 122 fitted in the long hole 128 further pushes up the lift plate 124, and the nozzle station 80 further rises. In other words, as the air cylinder 130 extends from the most contracted state to the most extended state, the nozzle station 80 rises from the position shown in FIG. 5 to the position shown in FIG. 7.

[0021] Furthermore, when the air cylinder 130 contracts from its most extended state, the shaft 126 of the arm 120 rotates counterclockwise, causing the arm 120 to swing counterclockwise. At this time, the cam follower 122 fixed to the tip of the arm 120 revolves counterclockwise and moves downward to the left. Then, as shown in FIG. 6, the cam follower 122 moves to the left of the shaft 126 of the arm 120, and reaches the left end inside the elongated hole 128 of the lifting plate 124. At this time, the cam follower 122 fitted in the elongated hole 128 presses down the lifting plate 124, causing the nozzle station 80 to descend.

[0022] Then, as the air cylinder 130 further contracts, the shaft 126 of the arm 120 rotates counterclockwise, and the arm 120 swings counterclockwise. At this time, the cam follower 122 fixed to the tip of the arm 120 further revolves counterclockwise and moves toward the lower right. Then, as the air cylinder 130 contracts to the maximum, the cam follower 122 moves directly below the shaft 126 of the arm 120 as shown in FIG. 5. In this way, the cam follower 122 moves directly below the shaft 126 of the arm 120, and reaches the right end inside the long hole 128 of the lift plate 124. At this time, the cam follower 122 fitted in the long hole 128 further presses down the lift plate 124, and the nozzle station 80 further descends. In other words, as the air cylinder 130 contracts from the maximum extended state to the maximum contracted state, the nozzle station 80 descends from the position shown in FIG. 7 to the position shown in FIG. 5.

[0023] In this manner, the lifting device 82 is operated, and the nozzle station 80 is lifted by the rotary air cylinder 88. When the nozzle station 80 is raised to the position shown in FIG. 7, the suction nozzle 66 mounted in the mounting hole 86 of the nozzle station 80 is inserted and attached to the working heads 60, 62. When the nozzle station 80 is raised to the position shown in FIG. 7, the suction nozzle 66 mounted on the working heads 60, 62 is inserted and placed in the mounting hole 86 of the nozzle station 80. However, when the suction nozzle 66 mounted in the mounting hole 86 of the nozzle station 80 is mounted on the working heads 60, 62 and when the suction nozzle 66 mounted on the working heads 60, 62 is placed in the mounting hole 86 of the nozzle station 80, the nozzle station 80 is pushed downward by the working heads 60, 62, and there is a risk that the nozzle station 80 will sink. That is, when the suction nozzle 66 is placed in the mounting hole 86 of the nozzle station 80 and when the suction nozzle 66 is attached to the working head, the nozzle station 80 may sink as it is pushed downward by the working heads 60, 62. In particular, when the suction nozzle 66 of the working head is placed in the mounting hole 86 located at the left end of the nozzle station 80 and in its vicinity, and when the suction nozzle 66 located at the left end of the nozzle station 80 and in its vicinity is attached to the working head, the nozzle station 80 may sink as it is pushed in the direction of arrow 150 by the working heads 60, 62, as shown in FIG.

[0024] Specifically, when the nozzle station 80 is pushed in the direction of the arrow 150 by the working heads 60, 62, the lift plate 124 is pushed in the direction of the arrow 152 as shown in FIG. 8. At this time, a counterclockwise moment is generated in the lift plate 124 with the cam follower 122 as a fulcrum. The lower end of the lift plate 124 is pushed in the direction of the arrow 156 by the moment generated in the lift plate 124. When the lower end of the lift plate 124 is pushed in the direction of the arrow 156, the cam follower 122 fitted in the linear elongated hole 128 cannot restrict the left-right movement of the lift plate 124, so the lower end of the lift plate 124 moves in the direction of the arrow 156. Therefore, the counterclockwise moment generated in the lift plate 124 causes the lift plate 124 to sink in the direction of the arrow 152 at the left end. That is, the counterclockwise moment generated in the lift plate 124 causes the lift plate 124 to swing about the cam follower 122 as a fulcrum. At this time, the nozzle station 80 sinks in the direction of arrow 150 (see FIG. 7) and tilts. In this way, when placing the suction nozzle 66 of the working head on the nozzle station 80 and when attaching the suction nozzle 66 of the nozzle station 80 to the working head, the nozzle station 80 sinks and tilts, making it impossible to properly place the suction nozzle 66 of the working head on the nozzle station 80 or attach the suction nozzle 66 of the nozzle station 80 to the working head.

[0025] In consideration of this, as shown in Fig. 9, the nozzle changer 34 is provided with a roller 160 for restricting the swing of the lift plate 124. More specifically, the nozzle changer 34 is provided with the roller 160 at a position facing the cam follower 122 when the lift plate 124 is at its highest position. The roller 160 is provided on the side surface of the base 110 so as to be rotatable about an axis parallel to the axis of the cam follower 122, and is in contact with the right edge of the lift plate 124 at a position facing the cam follower 122. Therefore, although the lower end of the lift plate 124 is pushed in the direction of the arrow 156 by the counterclockwise moment generated in the lift plate 124, the roller 160 in contact with the right edge of the lift plate 124 resists the force pushing in the direction of the arrow 156, thereby restricting the lift plate 124 from moving in the direction of the arrow 156. As a result, even if a counterclockwise moment is generated on the lift plate 124 when placing the suction nozzle 66 at the nozzle station 80 and attaching the suction nozzle 66 to the work head, the oscillation of the lift plate 124 is suppressed and the nozzle station 80 is prevented from sinking or tilting, so that the work of placing the suction nozzle 66 of the work head on the nozzle station 80 and the work of attaching the suction nozzle 66 of the nozzle station 80 to the work head can be performed properly.

[0026] Also, the right edge of the lift plate 124 with which the roller 160 comes into contact is a vertical surface 170 at about the lower ¼ position, and is an inclined surface 172 at a position above the vertical surface 170. Therefore, when the lift plate 124 is at its highest position, the roller 160 comes into contact with the vertical surface 170 at the right edge of the lift plate 124, thereby restricting the swinging of the lift plate 124. On the other hand, since the inclined surface 172 at the right edge of the lift plate 124 is inclined toward the inside of the lift plate 124 as it goes upward, when the lift plate 124 descends, the roller 160 faces the inclined surface 172 at the right edge of the lift plate 124, but does not come into contact with the inclined surface 172, as shown in FIG. In addition, the actual inclined surface 172 is inclined by only a few millimeters, but in Fig. 10, the inclined surface 172 is shown extremely inclined to show that the rollers 160 do not come into contact with the inclined surface 172 of the lifting plate 124 when the lifting plate 124 descends. In this way, by preventing the rollers 160 from coming into contact with the inclined surface 172 of the lifting plate 124 when the lifting plate 124 descends, the lifting plate 124 can be smoothly raised and lowered. In other words, when the lifting plate 124 is raised to the highest position to place the suction nozzle 66 at the nozzle station 80 and to attach the suction nozzle 66 to the work head, the rollers 160 come into contact with the vertical surface 170 of the lifting plate 124, thereby restricting the swinging of the lifting plate 124. On the other hand, when the lift plate 124 descends after the suction nozzle 66 has been placed at the nozzle station 80 and the suction nozzle 66 has been attached to the work head, the roller 160 descends smoothly without coming into contact with the inclined surface 172 of the lift plate 124.

[0027] In addition, the nozzle changer 34 is compact in the vertical direction because the nozzle station 80 is raised and lowered by the drive of the rotary air cylinder 88. More specifically, a notch 180 is formed in the frame 40 of the device body 20 in which the nozzle changer 34 is disposed, as shown in FIG. 11. Then, as shown in FIG. 12, the base 110 of the nozzle changer 34 is inserted into the notch 180, and the nozzle changer 34 is fixed to the frame 40 of the device body 20 on the upper surface of the base 110. A support plate 190 for supporting various wirings 188 is disposed below the nozzle changer 34, that is, below the nozzle changer 34 fixed to the frame 40. Therefore, the base 110 of the nozzle changer 34 is disposed between the support plate 190 and the frame 40, and when the nozzle station 80 is lowered, the lift plate 124 of the nozzle changer 34 is lowered to the immediate vicinity of the support plate 190, as shown in FIG. 13. In this way, the base 110 of the nozzle changer 34 is arranged in a very narrow space in the vertical direction. For this reason, the nozzle changer 34 employs a rotary air cylinder 88 as an actuator for raising and lowering the nozzle station 80, and the rotation of the output shaft of the rotary air cylinder 88 is converted into a vertical drive by using a cam mechanism 92 to raise and lower the lift plate 124, thereby making the nozzle changer 34 compact in the vertical direction. On the other hand, there is also a nozzle changer that raises and lowers the nozzle station by, for example, arranging a linear air cylinder to extend in the vertical direction and fixing the nozzle station to the tip of the rod of the air cylinder. Since such a nozzle changer is arranged so that the linear air cylinder extends in the vertical direction, the vertical size becomes large, and therefore it cannot be arranged in the arrangement space of the nozzle changer 34. In this way, the nozzle changer 34 employs a rotary air cylinder 88 as an actuator for raising and lowering the nozzle station 80, so that it can be arranged in a narrow space in the vertical direction.

[0028] In addition, the nozzle changer 34 employs the rotary air cylinder 88 as an actuator for raising and lowering the nozzle station 80, so that the state of the housed suction nozzle 66 can be maintained in a good condition even if the nozzle station 80 is raised and lowered. For example, when the nozzle station is raised and lowered by a linear air cylinder, the nozzle station rises and falls at a constant speed. Therefore, if the nozzle station suddenly stops when it is at its highest and / or lowest position and vibration occurs, there is a risk that the suction nozzle 66 housed in the mounting hole of the nozzle station will come out of the mounting hole. On the other hand, when the nozzle station 80 is raised and lowered by the rotary air cylinder 88, the rotation of the output shaft of the rotary air cylinder 88 is converted into a vertical drive by a cam mechanism to raise and lower the lift plate 124, so that the nozzle station 80 rises and falls at the fastest speed at a position between the highest and lowest positions. The nozzle station 80's ascending speed decreases as it ascends from the intermediate position to the highest position, and its descending speed decreases as it descends from the intermediate position to the lowest position. Therefore, in the nozzle changer 34, the nozzle station 80 stops gently when it ascends and / or descends to the highest position, thereby suppressing the occurrence of vibration. Thus, by employing the rotary air cylinder 88 as the actuator for raising and lowering the nozzle station 80, it is possible to prevent the housed suction nozzle 66 from coming out of the mounting hole as the nozzle station 80 ascends and descends.

[0029] In addition, the nozzle changer 34 employs a rotary air cylinder 88 as an actuator for raising and lowering the nozzle station 80, thereby preventing the nozzle station 80 from suddenly dropping due to the loss of air that drives the actuator. In more detail, for example, in a nozzle changer that raises and lowers the nozzle station by the extension and contraction of the rod of a linear air cylinder, the nozzle changer rises to the highest point when the rod of the air cylinder is fully extended. In this way, when the rod of the air cylinder is fully extended and the nozzle changer is at the highest point, if air that drives the air cylinder is lost, the rod of the air cylinder will suddenly contract due to the load of the nozzle station, causing the nozzle station to suddenly drop. On the other hand, in the nozzle changer 34 that raises and lowers the nozzle station 80 by driving the rotary air cylinder 88, as described above, when the nozzle changer is at the highest point, the air cylinder 130 that constitutes the rotary air cylinder 88 is fully extended. At this time, even if air escapes from the air cylinder 130, the load of the nozzle station 80 is received by the arm 120 facing vertically upward through the cam follower 122 fitted in the elongated hole 128 of the lift plate 124, as shown in Fig. 7. Since no rotating force acts on the arm 120 facing vertically upward, even if air escapes from the air cylinder 130, the nozzle station 80 at the highest position does not suddenly drop. In this way, by employing the rotary air cylinder 88 as the actuator that raises and lowers the nozzle station 80, it is possible to prevent the nozzle station 80 from suddenly dropping due to the escape of air that drives the actuator.

[0030] Incidentally, the component mounter 10 is an example of a mounting device. The nozzle changer 34 is an example of a holder storage device. The suction nozzle 66 is an example of a holder. The nozzle station 80 is an example of a storage station. The lifting device 82 is an example of a lifting device.

Specifically, for example, in the above embodiment, the rotary air cylinder 88 is used as the rotary actuator, but various rotary actuators such as a hydraulic rotary cylinder, an electromagnetic motor, etc. can be used.

[0032] In addition, in the above embodiment, the lifting device 82 uses the cam mechanism 92 to convert the rotation of the output shaft of the rotary air cylinder 88 into vertical drive to lift and lower the lifting plate 124, but various mechanisms such as a rack and pinion mechanism or a link mechanism may be used instead of the cam mechanism to convert the rotation of the output shaft of the rotary air cylinder 88 into vertical drive to lift and lower the lifting plate 124.

Also, the nozzle changer 34 may be fixed to the frame 40 of the apparatus body 20 at the lower surface of the base 110. In other words, the entire nozzle changer 34 may be disposed on the frame 40 of the apparatus body 20.
