Japanese Patent Laid-Open No. 11-74692

However, according to the attaching/detaching jig described in Patent Document 1, the tape cassette has a lift-up grip. The lift-up grip is designed to have a size that can be gripped by an operator. Therefore, when the lift-up grip is arranged on the tape cassette, the tape cassette becomes large.

Further, the lift-up grips project from the same position in all the tape cassettes arranged side by side on the set table. Therefore, when the attachment/detachment jig is attached/detached to/from any lift-up grip, the attachment/detachment jig easily interferes with the lift-up grip adjacent to the lift-up grip. That is, the workability of attaching/detaching the attaching/detaching jig to/from the lift-up grip is low.

Therefore, it is an object of the present invention to provide a component supply device and an electronic component mounter that enable downsizing of a component supply member and have high workability in attaching and detaching a gripping member.

In order to solve the above problems, the component supply device of the present invention includes a component supply table, a plurality of component supply members that are removably arranged on the component supply table, and store electronic components, and a plurality of the component supply members. And a gripping member that is detachably arranged and is shared by the plurality of component supply members. An electronic component mounter of the present invention is characterized by including the component supply device.

According to the component supply device and the electronic component mounter of the present invention, the gripping member can be shared by a plurality of component supply members. Therefore, it is possible to reduce the size of the component supply member as compared with the case where the grips (for example, lift-up grips) are individually provided to all the component supply members. Moreover, the number of parts of the component supply member can be reduced. Further, the manufacturing cost of the component supply member can be reduced.

Moreover, the component supply member does not include a grip portion. Therefore, when the grip member is attached to or detached from an arbitrary component supply member, the grip member does not easily interfere with the component supply member adjacent to the component supply member. As described above, according to the component supply device and the electronic component mounter of the present invention, workability of attaching/detaching the gripping member to/from the component supply member is improved.

<Motion of electronic component mounter>
Next, the movement of the electronic component mounting machine of this embodiment when replacing the feeder cassette will be described. FIG. 6 shows a partial front and rear sectional view of the feeder cassette and the handle of the component supply device according to the present embodiment in a state where the handle is attached to the feeder cassette. FIG. 7 shows an enlarged view of the inside of the frame VII of FIG. FIG. 8 shows an enlarged view of the inside of the frame VIII of FIG. FIG. 9 shows an enlarged view within the frame IX of FIG.

In the feeder cassette replacement work, as shown in FIGS. 3 and 6, first, the worker attaches the handle 42 to the feeder cassette 40 attached to the device pallet 41. Specifically, the pair of front and rear lower ends 420 of the handle 42 is inserted into the pair of front and rear first cylinders 437 from the upper side. At this time, as shown in FIGS. 4 and 7, the pair of front and rear engaging claws 434 ride over the opening edge of the first cylinder 437 to the front and rear inner sides. The pair of front and rear engagement claws 434 which have passed over the opening edge are moved to the front and rear outer sides by the urging force of the second spring 436. That is, the pair of front and rear engagement claws 434 are locked in the pair of front and rear engagement recesses 438. The engagement claw 434 engages with the engagement recess 438, so that the handle 42 is locked to the feeder cassette 40.

Further, the first movable member 440 is pushed down by the lower end 420. The first movable member 440 moves downward against the biasing force of the third spring 441. The first movable member 440 and the second movable member 445 are connected via the second cable 447. Therefore, as shown in FIGS. 5 and 8, when the first movable member 440 moves downward, the second movable member 445 moves upward against the biasing force of the fourth spring 446. That is, the second movable member 445 is extracted from the engagement recess 411 on the upper surface of the device pallet 41. Therefore, the feeder cassette 40 is switched from the locked state (the state in which it cannot be removed from the device pallet 41) to the unlocked state (the state in which it can be removed from the device pallet 41).

Further, as shown in FIGS. 5 and 8, when the second movable member 445 moves upward, the power lever 448 swings upward against the biasing force of the fifth spring 449. Therefore, the power supply of the feeder cassette 40 is switched from on (a state in which the motor 405 and the like can be driven) to off (a state in which the motor 405 and the like cannot be driven).

Next, the operator removes the feeder cassette 40 from the device pallet 41 by gripping the handle 42 and pulling it up. Then, the operator places the removed device pallet 41 on a carriage (not shown). Then, the operator removes the handle 42 from the device pallet 41. Specifically, as shown in FIG. 9, the operator slides the slider 432 to the front side against the biasing force of the first spring 433. The slider 432 and the pair of front and rear engagement claws 434 are connected via a first cable 435. Therefore, when the operator slides the slider 432 to the front side, the pair of front and rear engagement claws 434 move inward and backward both sides against the biasing force of the second spring 436. That is, the engagement between the pair of front and rear engagement claws 434 and the pair of front and rear engagement recesses 438 is released. Thus, the operator slides the slider 432 to the front side to unlock the handle 42 from the feeder cassette 40. The operator removes the handle 42 from the feeder cassette 40 by pulling up the handle 42 in the unlocked state.

After that, as shown in FIGS. 3 and 6, the worker attaches the handle 42 to the new feeder cassette 40 of the trolley. Subsequently, the worker attaches the feeder cassette 40 to the device pallet 41. Finally, the operator removes the handle 42 from the feeder cassette 40. When the handle 42 is removed, the first movable member 440 is moved upward by the biasing force of the third spring 441 as shown in FIGS. 7 and 4. Therefore, as shown in FIGS. 8 and 5, the second movable member 445 is moved downward by the biasing force of the fourth spring 446. That is, the second movable member 445 is inserted into the engaging recess 411 on the upper surface of the device pallet 41. Therefore, the feeder cassette 40 switches from the unlocked state to the locked state. Further, the power supply lever 448 swings downward due to the biasing force of the fifth spring 449. Therefore, the power supply of the feeder cassette 40 is switched from off to on.

<Effect>
Next, the function and effect of the electronic component mounter of this embodiment will be described. As shown in FIG. 1, according to the electronic component mounter 1 of the present embodiment, the handle 42 can be shared by the plurality of feeder cassettes 40. Therefore, the feeder cassette 40 can be downsized as compared with the case where gripping portions (for example, lift-up grips) are individually provided to all the feeder cassettes 40. Further, the number of parts of the feeder cassette 40 can be reduced. Further, the manufacturing cost of the feeder cassette 40 can be reduced.

As shown in FIG. 1, the feeder cassette 40 does not have a grip portion. Therefore, when the handle 42 is attached to or detached from any feeder cassette 40, the handle 42 is unlikely to interfere with the feeder cassette 40 adjacent to the feeder cassette 40. As described above, according to the electronic component mounter 1 of the present embodiment, workability of attaching/detaching the handle 42 to/from the feeder cassette 40 is improved.

As shown in FIGS. 4 and 7, the common switching portion 43 includes an engagement claw (grip member side engagement portion) 434, an engagement recess (a component supply member side engagement portion) 438, and a second spring (attachment). And a biasing member) 436. Therefore, the handle 42 can be locked to the feeder cassette 40 only by attaching the handle 42 to the feeder cassette 40. Therefore, it is easy to lock the handle 42 with respect to the feeder cassette 40. Further, even if the handle 42 is lifted after being locked, the feeder cassette 40 is unlikely to drop from the handle 42.

As shown in FIG. 9, the shared switching section 43 includes a slider (input section) 432, an engaging claw (grip member side engaging section) 434, and a first cable (power transmission member) 435. There is. Therefore, only by moving the slider 432, the handle 42 can be unlocked with respect to the feeder cassette 40. Further, the operator can operate the slider 432 with only the thumb while holding the handle 42. Therefore, the operability of the slider 432 is high.

As shown in FIGS. 3, 5, 6, and 8, the shared switching unit (power switching unit) 43 includes a first movable member 440, a second movable member 445, and a second cable (power transmission member) 447. And a power supply lever (power supply sensor) 448 and a fifth spring (biasing member) 449. The power supply lever 448 is urged downward (on the power-on side of the feeder cassette 40) by the fifth spring 449. By attaching the handle 42 to the feeder cassette 40, the first movable member 440 moves, the second cable 447 moves in conjunction with the first movable member 440, and the second movable member 445 in conjunction with the second cable 447. And the power lever 448 swings upward (power off side of the feeder cassette 40) in conjunction with the second movable member 445. As described above, according to the electronic component mounting machine 1 of the present embodiment, the power supply of the feeder cassette 40 can be switched from on to off simply by attaching the handle 42 to the feeder cassette 40. In addition, the power supply of the feeder cassette 40 can be switched from off to on simply by removing the handle 42 from the feeder cassette 40. That is, the power supply of the feeder cassette 40 can be switched in association with the attachment/detachment of the handle 42 to/from the feeder cassette 40. Therefore, it is easy to switch the power supply of the feeder cassette 40. In addition, it is possible to reliably execute the work of switching the power supply. Further, the power switch (that is, the handle 42) can be shared by the plurality of feeder cassettes 40. The power lever 448 is arranged on the feeder cassette 40. For this reason, the circuit configuration for switching the power supply of the feeder cassette 40 becomes simple as compared with the case where the power supply lever 448 is arranged on the device pallet 41.

As shown in FIGS. 3, 5, 6, and 8, the shared switching unit (lock mechanism unit) 43 includes a first movable member 440, a second movable member 445, a first movable member 440, and a second movable member. It has a second cable (power transmission member) 447 that connects the member (component supply member side engaging portion) 445, and a fourth spring (biasing member) 446. The second movable member 445 is urged downward by the fourth spring 446 (on the side that engages with the engaging recess (part supply table side engaging portion) 411). By attaching the handle 42 to the feeder cassette 40, the first movable member 440 moves, the second cable 447 moves in conjunction with the first movable member 440, and the second movable member 445 in conjunction with the second cable 447. Are interlocked with each other, and the second movable member 445 moves to the upper side (the side that is disengaged from the engaging recess 411). As described above, according to the electronic component mounter 1 of the present embodiment, the feeder cassette 40 can be switched from the locked state to the unlocked state only by attaching the handle 42 to the feeder cassette 40. In addition, the feeder cassette 40 can be switched from the unlocked state to the locked state simply by removing the handle 42 from the feeder cassette 40. That is, the state of the feeder cassette 40 can be switched in association with the attachment/detachment of the handle 42 to/from the feeder cassette 40. For this reason, it is easy to switch the state (locked/unlocked) of the feeder cassette 40. In addition, it is possible to reliably execute the state switching work. Further, the status changeover switch (that is, the handle 42) can be shared by the plurality of feeder cassettes 40.

As shown in FIG. 1, the handle 42 has a C-shape that opens downward. Therefore, the operator can easily pull up the handle 42 together with the feeder cassette 40. Further, the operator can easily slide the handle 42 together with the feeder cassette 40 to the front side. Thus, the C-shaped handle 42 has high operability.

As shown in FIG. 3, the electronic component mounter 1 of this embodiment includes a shared switching unit 43. Therefore, the number of components of the component supply device 4 can be reduced as compared with the case where the power supply switching unit and the lock mechanism unit are separately arranged. Further, the installation space for the power source switching unit and the lock mechanism unit can be narrowed.

<Other>
The embodiments of the component supply device and the electronic component mounter of the present invention have been described above. However, the embodiment is not particularly limited to the above embodiment. It is also possible to implement in various modified forms and improved forms that can be performed by those skilled in the art.

For example, the arrangement of the engagement claw 434 and the engagement recess 438 shown in FIG. 7 may be reversed. That is, the engaging recess 438 may be arranged in the handle 42, and the engaging claw 434 may be arranged in the feeder cassette 40.

The locking mechanism of the handle 42 with respect to the feeder cassette 40 shown in FIG. 7 and the locking mechanism of the feeder cassette 40 with respect to the device pallet 41 shown in FIG. 8 are not particularly limited. For example, magnetic force by an electromagnet or the like may be used for these lock mechanisms.

The type of power supply sensor is not particularly limited. Instead of the power lever 448 shown in FIG. 8, various sensors (which can detect the position and movement of the second movable member 445 and send a power switching instruction to the control device 406 (or the control device of the electronic component mounter 1) ( Proximity sensor, limit switch, etc.) may be arranged. The power supply sensor may detect the position and movement of the first movable member 440, and may send a power supply switching instruction to the control device 406 (or the control device of the electronic component mounting machine 1).

The panel (input unit) 403a may be arranged on the handle 42. By doing so, the number of parts of the feeder cassette 40 can be reduced. Further, the types of buttons arranged on the panel 403a are not particularly limited. For example, a button for operating the feeder cassette 40 (a power on/off switching button of the feeder cassette 40, a lock/unlock switching button of the feeder cassette 40 for the device pallet 41) may be used.

The type of gripping member is not particularly limited. Instead of the handle 42 shown in FIG. 1, a stick-shaped gripping member may be arranged. The attachment/detachment position of the handle 42 on the feeder cassette 40 is not particularly limited. For example, it may be the front surface (the surface on the work area side) of the feeder cassette 40. That is, it is only necessary that the feeder cassette 40 can be accessed when the plurality of feeder cassettes 40 are lined up on the device pallet 41.

The number of feeder cassettes 40 and handles 42 arranged is not particularly limited. For example, the number of handles 42 arranged may be smaller than the number of feeder cassettes 40 arranged. By doing so, the number of components of the component supply device 4 can be reduced. Further, the handle 42 may be shared by a plurality of types of feeder cassettes 40. By doing so, the number of components of the component supply device 4 can be reduced. Further, the handle 42 may be differentiated depending on the type of the feeder cassette 40. In this case, the handle 42 for the feeder cassette 40 of an arbitrary type cannot be attached to the feeder cassette 40 of another type. Therefore, the feeder cassette 40 can be easily identified. Further, instead of the shared switching unit 43, the power switching unit and the lock mechanism unit may be separately arranged.
