The control section 8 is configured to cooperate with the control circuit 301 of each of the plurality of tape feeders 30 to control the mounting operation.

Here, in this embodiment, the component mounting apparatus 100 is provided with a stopper 9 that restricts movement of the moving mechanisms 5 and 6 . Specifically, the stopper 9 is configured to restrict outward movement in the Y direction of the moving mechanism 5 that supports the head unit 4 (the plurality of mounting heads 42). The stopper 9 includes a contact portion 91 and an air cylinder 92, as shown in FIGS. The abutting portion 91 abuts on the moving mechanism 5 that supports the head unit 4, thereby restricting the moving mechanism 5 from moving outward in the Y direction. The contact portion 91 is made of an elastic material. The contact portion 91 is made of, for example, an elastic resin such as urethane.

Further, in this embodiment, the stopper 9 is configured such that the position for restricting the movement of the moving mechanisms 5 and 6 can be switched according to the type of the tape feeder 30 . Here, as shown in FIG. 2, in the type A tape feeder 30a, the component supply position 311 in the Y direction is the position Ya.

The position Yc of the component supply position 311 of the tape feeder 30b is set so that the larger the size (width) of the component, the further out in the Y direction. Further, the position Yc of the component supply position 311 of the tape feeder 30b is arranged outside the position Ya of the component supply position 311 of the tape feeder 30a in the Y direction.

Therefore, the stopper 9 restricts movement of the moving mechanism 5 by the moving mechanism 6 so that the tape feeder 30 does not interfere (contact) with the moving mechanism 5 and the head unit 4 according to the type of the tape feeder 30 . That is, when the component supply position 311 is the position Ya and the tape feeder 30a located inside the position Yc in the Y direction is arranged in the component supply section 3, the position regulated by the stopper 9 is the position Yb. Further, when the component supply position 311 is the position Yc and the tape feeder 30b located outside the position Ya in the Y direction is arranged in the component supply unit 3, the position to be regulated by the stopper 9 is outside the position Yb. Let the position be Yd.

Further, the stopper 9 is configured to switch the position for restricting the movement of the moving mechanisms 5 and 6 by expanding and contracting. Specifically, the stopper 9 includes an extendable air cylinder 92 . By extending the air cylinder 92, as shown in FIG. 2, the position where the movement of the moving mechanisms 5 and 6 is restricted is defined as a position Yb. Further, by shortening the air cylinder 92, as shown in FIG. 3, the position where the movement of the moving mechanisms 5 and 6 is restricted is defined as a position Yd.

Note that when the movement of the moving mechanisms 5 and 6 is controlled by the control unit 8, the moving mechanism 5 and the head unit 4 are not moved to the position where they contact the stopper 9 (contact portion 91). However, when the moving mechanisms 5 and 6 are powered off and the servo is turned off, the moving mechanisms 5 and 6 can be manually moved by the user. In this case, the moving mechanism 5 and the head unit 4 may be moved to a position where the stopper 9 (abutting portion 91) abuts.

Also, the stopper 9 is provided in the component mounting apparatus main body 101 in which the mounting head 42 and the moving mechanisms 5 and 6 are arranged. The stopper 9 is provided on the frame of the component mounting apparatus main body 101 . Also, the stoppers 9 are provided near both ends in the X direction.

The control unit 8 recognizes the type of the tape feeder 30 , expands and contracts the stopper 9 , and performs control to switch the positions for restricting the movement of the moving mechanisms 5 and 6 . Specifically, the control section 8 is configured to recognize the type of the tape feeder 30 based on the identification section 302 provided in the tape feeder 30 . That is, the control section 8 is configured to recognize the type of the tape feeder 30 based on the identification information of the tape feeder 30 stored in the identification section 302 of the control circuit 301 of the tape feeder 30 . Then, based on the acquired identification information of the tape feeder 30, the control unit 8 performs control to move the stopper 9 to the corresponding position.

Further, the control unit 8 controls the movement range of the mounting head 42 by the movement mechanisms 5 and 6 according to the type of the tape feeder 30 . Specifically, the control unit 8 controls the movement range of the mounting head 42 in the Y direction by the moving mechanisms 5 and 6 according to the component supply position 311 of the tape feeder 30 in the Y direction. That is, the control unit 8 can suck the component 31 by the mounting head 42 from the component supply position 311 of the tape feeder 30 installed in the component supply unit 3, and the moving mechanism 5 and the head unit 4 can be attached to the tape feeder. Control is performed to limit the movement range of the mounting head 42 in the Y direction by the movement mechanisms 5 and 6 so that the mounting head 42 does not reach a position that interferes with the mounting head 30 . Further, the control unit 8 selects a soft limit as a parameter for moving the Y axis to a corresponding value, and performs control to limit the range of movement of the mounting head 42 in the Y direction by the moving mechanisms 5 and 6 .

Further, the control unit 8 is configured to notify an error when a plurality of tape feeders 30 having different positions for regulating movement of the moving mechanisms 5 and 6 are arranged in the same component supply unit 3. . When an error occurs, the control unit 8 displays the error on the display unit 81 and notifies it.

If the type of the tape feeder 30 is type A, the process proceeds to step S13, and if the type of the tape feeder 30 is type B, the process proceeds to step S15.

At step S13, the stopper 9 is extended. This shortens the physical stroke (movement range) of the mounting head 42 in the Y direction. In step S14, axis parameters such as soft limits for the type A tape feeder 30 are selected. This shortens the controllable stroke (movement range) of the mounting head 42 in the Y direction. After that, the process proceeds to step S17.

At step S15, the stopper 9 is shortened. This lengthens the physical stroke (movement range) of the mounting head 42 in the Y direction. In step S16, axis parameters such as soft limits for type B tape feeder 30 are selected. This lengthens the controllable stroke (movement range) of the mounting head 42 in the Y direction. After that, the process proceeds to step S17.

In step S17, substrate production is started. The component 31 is mounted on the board S in step S18.
