<Mounting work on a circuit board having a non-flat mounting surface>
The substrate holder 100 having the above-described configuration is conveyed by the conveying device 20 of the electronic component mounting machine 10, and the fixing plate 102 is fixedly held by the substrate holding device of the conveying device 20. Thereby, in the electronic component mounting machine 10, it is possible to perform mounting work on the circuit board 116 held by the board holder 100. Specifically, first, the circuit board 116 is held by the board holding part 112 so that the longitudinal direction of the board holding part 112 and the longitudinal direction of the circuit board 116 coincide with each other. Then, the substrate holder 100 is supported by the conveyor belt 30 of the transport device 20 so that the longitudinal direction of the substrate holder 112, that is, the direction in which the swing center of the substrate holder 112 extends coincides with the X-axis direction. .

  The substrate holder 100 supported by the conveyor belt 30 is conveyed to a work position in accordance with a command from the control device of the electronic component mounting machine 10, and the fixing plate 102 of the substrate holder 100 is fixed by the substrate holder at that position. Retained. Then, the mounting head 24 moves to above the operation switch 128 of the substrate holder 100 and moves the suction nozzle 70 downward by operating the operation switch 128 according to a command from the control device. Thereby, the board | substrate holding | maintenance part 112 rock | fluctuates and the plane in which the 1st mounting part 118a of the circuit board 116 is located becomes horizontal.

  Further, the tape feeder 80 sends out a taped component and supplies an electronic component at a supply position in accordance with a command from the control device. Then, the mounting head 24 moves above the supply position of the electronic component according to a command from the control device, and sucks and holds the electronic component by the suction nozzle 70. Subsequently, the mounting head 24 moves above the first mounting portion 118a of the circuit board 116 and mounts the held electronic component on the first mounting portion 118a. By repeating this operation, electronic components are mounted on the plurality of first mounting portions 118a.

  When electronic components are mounted on the plurality of first mounting portions 118a, the mounting head 24 moves above the operation switch 130 of the substrate holder 100 and moves the suction nozzle 70 downward according to a command from the control device. Then, the operation switch 130 is operated. Thereby, the board | substrate holding part 112 rock | fluctuates and the plane in which the 2nd mounting part 118b of the circuit board 116 is located becomes horizontal. Then, similarly to the mounting operation for the first mounting portion 118a, the mounting operation is performed for the plurality of second mounting portions 118b.

  When the electronic components are mounted on the plurality of second mounting portions 118b, the mounting head 24 moves above the operation switch 132 of the substrate holder 100 and moves the suction nozzle 70 downward according to a command from the control device. As a result, the operation switch 130 is operated. Thereby, the board | substrate holding part 112 rock | fluctuates, and the plane in which the 3rd mounting part 118c of the circuit board 116 is located becomes horizontal. Then, similarly to the mounting operation for the first mounting portion 118a, the mounting operation is performed for the plurality of third mounting portions 118c. The operation switch 134 is not operated during the mounting work on the circuit board 116, but is operated when the circuit board needs to be rotated around the axis extending in the vertical direction during the mounting work on the circuit board having another shape.

This makes it possible to perform the mounting operation on the circuit board 116 having a non-flat mounting surface without attaching a new mechanism or the like to the conventional electronic component mounting machine, which is very economical.

  The substrate holder 100 is provided with a control device 126 that controls the operation of the electromagnetic motors 120 and 122. The substrate holder 100 is inclined with respect to the horizontal plane of the circuit board 116, that is, the circuit board 116. The holding posture can be changed to be controllable. For this reason, it is not necessary to control the operation of the electromagnetic motors 120 and 122 by the electronic component mounting machine 10, and it is not necessary to transmit / receive command data and the like between the electronic component mounting machine 10 and the substrate holder 100. As a result, the conventional electronic component mounting machine can be mounted on the circuit board 116 having a non-flat mounting surface without providing a new control device, data transmitter / receiver, or the like.

  Furthermore, in the substrate holder 100, operation switches 128, 130, 132, and 134 for operating the electromagnetic motors 120 and 122 are exposed on the upper surface of the substrate holder 100. For this reason, when the operation switches 128, 130, 132, and 134 are operated by the mounting head 24 of the electronic component mounting machine 10, the inclination angle of the circuit board 116 with respect to the horizontal plane changes. Thereby, the electronic component mounting machine 10 can change the inclination angle of the circuit board 116 at an arbitrary timing, and can efficiently perform the mounting operation. In addition, during execution of the mounting program, it is possible to create a standard mounting program by moving the mounting head 24 to a predetermined position and pressing an operation switch.

It is transmitted to the electromagnetic motors 120 and 122, and the operation of the electromagnetic motors 120 and 122 is controlled by the command data.

  Moreover, in the said Example, although the electromagnetic motors 120 and 122 for changing the inclination-angle of the circuit board 116 are provided in the board | substrate holder 100, even if it is a board | substrate holder in which an electromagnetic motor is not provided, It is possible to perform mounting work on the circuit board 116 by the electronic component mounting machine 10. Specifically, for example, the substrate holder 140 shown in FIG. 3 will be described below as an example of a substrate holder that is not provided with an electromagnetic motor.

Thereby, the board | substrate holder 140 holding the circuit board 116 is conveyed in order of the electronic component mounting machine 10a, the working machine 150, and the electronic component mounting machine 10b.

  The work machine 150 further includes a rotation mechanism 154 and a swing mechanism 156. The rotation mechanism 154 is a mechanism for rotating the rotating plate 144 of the substrate holder 140 conveyed by the conveyance device 152, and the swing mechanism 156 is a substrate holding portion of the substrate holder 140 conveyed by the conveyance device 152. It is a mechanism for swinging 112.

  In the system having the above structure, the substrate holder 140 is transported by the transport device 20 of the electronic component mounting machine 10a so that the plane on which the first mounting portion 118a of the circuit board 116 is positioned is horizontal, and the electronic component mounting machine is used.
