When at least one of the two front and rear inspection doors 12C is opened, the component mounting device 1 detects this and detects the two transport lanes 13, the parts feeder 22, the head moving mechanism 15, and the two mounting heads 16. It is equipped with a safety device that forcibly stops each operation of. With this safety device, the safety of the worker is ensured even when the worker inserts his / her hand into the work space 11S with the inspection door 12C open.

Next, the flow of the component mounting operation in which the component mounting device 1 mounts the component 3 on the substrate 2 will be described. In the component mounting operation, first, the transport lane 13 controlled by the control device 80 receives the substrate 2 sent from the device on the upstream process side, transports it, and positions it at the work position. When the substrate 2 is positioned at the working position, the head moving mechanism 15 moves the mounting head 16 above the parts feeder 22. The mounting head 16 lowers the shaft member 31 from above the parts feeder 22 and attracts the parts 3 supplied by the parts feeder 22 to the parts supply port 22K to the nozzle 32.

After the component 3 is attracted to the nozzle 32, the mounting head 16 moves above the component camera 17 and causes the component camera 17 to take an image of the component 3. The component camera 17 captures an image of the component 3 located above. The mounting head 16 moves above the substrate 2 after the component 3 is imaged by the component camera 17. Then, the shaft member 31 is lowered above the component mounting position on the substrate 2, and the component 3 is mounted at the component mounting position based on the recognition result of the component 3 by the component camera 17.

The component 3 is mounted on the board 2 by repeating such a component mounting operation, but when the model of the board 2 to be produced is switched, the nozzle 32 attached to the mounting head 16 is replaced. Needs arise. In this case, the mounting head 16 replaces the nozzle 32 via the nozzle switching table 18, but before that, the nozzle switching table 18 holding the replacement nozzle 32 is installed at the switching table installation position 11N. Work needs to be done.

If there is already a nozzle exchange table 18 installed in the work space 11S at the time of executing the nozzle exchange table installation work (nozzle exchange table installation method), before performing the nozzle exchange table installation work. , Execute the exchange table removal work (nozzle replacement table removal method) described below. The work of taking out the exchange table is the work of taking out the nozzle exchange table 18 installed in the work space 11S.

In the work of taking out the exchange table, the operator first performs a predetermined operation from the touch panel 81. The switching table fixing portion 20 controlled by the control device 80 thereby releases the fixing of the nozzle switching table 18 fixed to the switching table installation position 11N (fixing release step).

In the fixing release step, first, the pair of clamp members 73 move in a direction away from each other to release the clamps of the two legs 43 of the nozzle exchange table 18 (FIGS. 14 (a) → 14 (b)). .. When the clamp of the nozzle exchange table 18 is released, the elevating cylinder 71 lowers the elevating block 72 (FIG. 14 (b) → FIG. 15 (a)), and the base portion 41 of the nozzle exchange table 18 is placed on the installation unit side conveyor 63. (Fig. 15 (a)). When the base portion 41 of the nozzle switching table 18 is placed on the conveyor 63 on the installation portion side, the fixing release step is completed.

When the fixing release step is completed, the switching table transport unit 19 transports the nozzle switching table 18 to the switching table entrance / exit 50 (discharge transfer step). Specifically, in the discharge transfer step, first, the installation unit side conveyor 63 conveys the nozzle exchange table 18 (arrow A shown in FIG. 15B) and delivers it to the relay conveyor 62 (FIG. 16A). → FIG. 16 (b)). When the relay conveyor 62 receives the nozzle exchange table 18 from the installation unit side conveyor 63, the relay conveyor 62 rotates 90 degrees in the horizontal plane to direct the transport direction of the nozzle exchange table 18 toward the supply port side conveyor 61 (FIG. 16 (FIG. 16). b) → FIG. 17 (a)).

When the relay conveyor 62 directs the transfer direction of the nozzle exchange table 18 toward the supply port side conveyor 61, the relay conveyor 62 conveys the nozzle exchange table 18 and delivers it to the supply port side conveyor 61 (FIG. 17A → FIG. 17). (B)). In the process of transferring the nozzle exchange table 18, the relay conveyor 62 conveys the direction of the nozzle exchange table 18 to a direction (Y-axis direction) orthogonal to the transfer direction (X-axis direction) of the substrate 2 by the transfer lane 13. The change is made between the transport direction of the substrate 2 by the lane 13 and the direction parallel to the transport direction (X-axis direction). That is, in the present embodiment, the relay conveyor 62 is a direction changing unit that changes the direction of the nozzle changing table 18 during transportation.

The supply port side conveyor 61 that has received the nozzle exchange table 18 from the relay conveyor 62 conveys the received nozzle exchange table 18, and positions the head portion of the nozzle exchange table 18 at the exchange table entrance / exit 50. Next, when the switching table detection sensor 53 detects that the nozzle switching table 18 is located at the switching table entrance / exit 50, the supply port cover drive unit 52 operates to open the supply port cover 51. When the supply port cover 51 is opened, the operator pulls out the nozzle exchange table 18 from the exchange table entrance / exit 50 and takes it out. This completes the work of taking out the exchange table.

When the switching table removal work is completed, the operator arranges the nozzle switching table 18 holding the replacement nozzle 32 at the switching table entrance / exit 50 in which the supply port cover 51 is opened and opened. Specifically, the operator places the nozzle exchange table 18 holding the replacement nozzle 32 on the supply port side conveyor 61.

After supplying the nozzle exchange table 18 from the exchange table entrance / exit 50, the operator performs a predetermined operation from the touch panel 81. As a result, the supply port cover 51 is closed, and the switching table transport unit 19 transports the nozzle switching table 18 supplied from the switching table entrance / exit 50 to the switching table installation position 11N (conveying process).

Specifically, in the transfer step, first, the supply port side conveyor 61 conveys the nozzle exchange table 18 and delivers it to the relay conveyor 62 (FIG. 18 (a) → FIG. 18 (b)). When the relay conveyor 62 receives the nozzle exchange table 18 from the supply port side conveyor 61, the relay conveyor 62 rotates 90 degrees in the horizontal plane to direct the transport direction of the nozzle exchange table 18 toward the installation unit side conveyor 63 (FIG. 18 (FIG. 18). b) → FIG. 19 (a)).

When the relay conveyor 62 directs the transfer direction of the nozzle exchange table 18 toward the installation unit side conveyor 63, the relay conveyor 62 conveys the nozzle exchange table 18 and delivers it to the installation unit side conveyor 63 (FIG. 19A → FIG. 19). (B)). Also in the process of transferring the nozzle exchange table 18, the relay conveyor 62 sets the direction of the nozzle exchange table 18 to be orthogonal to the transfer direction (X-axis direction) of the substrate 2 by the transfer lane 13 (Y-axis direction). It functions as a direction changing unit that changes the direction of the substrate 2 by the transport lane 13 in a direction parallel to the transport direction (X-axis direction) and changes the direction of the nozzle exchange table 18 during transport.

The installation unit side conveyor 63, which has received the nozzle exchange table 18 from the relay conveyor 62, conveys the nozzle exchange table 18 (arrow B shown in FIG. 20A), and the exchange table installation position 11N (above the elevating block 72). Position) (FIG. 20 (a)). When the nozzle exchange table 18 is located at the exchange table installation position 11N, the transfer process is completed.

When the transfer process is completed, the exchange table fixing unit 20 fixes the nozzle exchange table 18 transported by the exchange table transfer unit 19 to the exchange table installation position 11N at the exchange table installation position 11N (that is, with respect to the base 11). Fixing process). In the fixing step, as described above, after the elevating cylinder 71 raises the elevating block 72 to lift the nozzle exchange table 18 and separate it upward from the installation unit side conveyor 63 (FIG. 20 (a) → FIG. 20 (FIG. 20). b)), the pair of clamping members 73 move in a direction close to each other to clamp the two legs 43 (FIG. 20 (b) → FIG. 21 (a)). When the fixing process is completed, the nozzle exchange table installation work is completed.

In the above-mentioned switching table installation work of the nozzle switching table 18 and the switching table removal work before that, the operator supplies the nozzle switching table 18 from the switching table entrance / exit 50 connected to the work space 11S and opened to the outside of the cover member 12. Further, the nozzle exchange table 18 is taken out from the exchange table entrance / exit 50, and it is not necessary to open the inspection door 12C provided on the cover member 12. Therefore, the component mounting work is not stopped by the safety device, and even if it becomes necessary to switch models for one of the two transport lanes 13, the other transport lane 13 that is not the target of model switching is not subject to model switching. The component mounting operation can be continued, and the decrease in board productivity can be prevented.

When the nozzle changing table installation work is completed, the mounting head 16 moves above the nozzle changing table 18 to replace the nozzle 32. In the replacement of the nozzle 32, the nozzle 32 attached to the shaft member 31 is held by the nozzle switching table 18 and removed from the shaft member 31, and then the replacement nozzle 32 held by the nozzle changing table 18 is replaced. Is attached to the shaft member 31. At this time, when there are a plurality of shaft members 31 for attaching and detaching the nozzle 32, the removal operation of the nozzle 32 and the attachment operation of the nozzle 32 are collectively executed for the plurality of shaft members 31.

When removing the nozzle 32 attached to the shaft member 31, first, the opening / closing cylinder 74 moves the operation rod 75 in the X-axis direction to slide the shutter member 42 with respect to the base portion 41. The shutter member 42 is positioned from the "closed position" (FIG. 21 (a)) to the "open position" (FIG. 21 (b)). Then, the mounting head 16 moves to align the vertical center axis of the nozzle 32 with the vertical center axis of the nozzle insertion hole 41H of the nozzle exchange table 18. When the vertical center axis of the nozzle 32 and the vertical center axis of the nozzle insertion hole 41H match, the shaft member 31 is lowered to insert the nozzle 32 into the nozzle insertion hole 41H.

After the nozzle 32 is inserted into the nozzle insertion hole 41H, the shutter member 42 is positioned from the open position (FIG. 21 (b)) to the closed position (FIG. 21 (a)), and then the shaft member 31 is pulled upward. At this time, since the flange portion 32c of the nozzle 32 interferes with the shutter member 42 and the upward movement is hindered, the nozzle 32 is pulled out from the shaft member 31 and the nozzle 32 remains on the nozzle exchange table 18. As a result, the nozzle 32 is removed from the shaft member 31.

Next, the replacement nozzle 32 is attached to the shaft member 31 from which the nozzle 32 has been removed. To do this, first, the mounting head 16 is moved to position the shaft member 31 above the replacement nozzle 32 held by the nozzle replacement table 18. Then, by aligning the vertical center axis of the nozzle 32 with the vertical center axis of the shaft member 31 and lowering the shaft member 31, the base portion 32a of the nozzle 32 is coupled (outerly fitted) to the lower end of the shaft member 31.

When the base portion 32a of the nozzle 32 is connected to the lower end of the shaft member 31, the opening / closing cylinder 74 moves the operation rod 75 in the X-axis direction to move the shutter member 42 from the closing position (FIG. 21A) to the opening position (FIG. 21). (B)). When the shutter member 42 is in the open position, the mounting head 16 pulls up the shaft member 31 upward. As a result, the nozzle 32 is pulled up in a state of being coupled to the lower end of the shaft member 31, and the replacement of the nozzle 32 is completed.
