Component feeder and component mounter

The present invention relates to a component supply device and a component mounting device, and more particularly to a component supply device and a component mounting device having a tape feeding section that feeds a component supply tape to a suction position where a nozzle picks up a component.

Conventionally, there has been known a component supply device equipped with a tape feeding section that feeds a component supply tape to a pickup position where a nozzle picks up a component. Such a component supply device is disclosed in Japanese Unexamined Patent Application Publication No. 2012-18999, for example.

The above-mentioned JP-A-2012-18999 discloses an electronic component supply device (component supply device) provided with a transport mechanism (tape feeder) that feeds a component supply tape to a component supply position (sucking position) where an electronic component is sucked by a nozzle. disclosed. The transport mechanism is configured to transport the component supply tape to the component pickup position by accelerating and decelerating. Here, the component supply tape includes a carrier tape and a cover tape. The carrier tape has a plurality of recesses for storing electronic components. A cover tape covers the upward opening of each of the plurality of recesses.

JP 2012-18999 A

However, in the electronic component supply device disclosed in JP-A-2012-18999, after the cover tape is peeled off at the peeling position by the peeling mechanism, the carrier tape is transported to the component supply position by accelerating and decelerating the transport mechanism. Therefore, the electronic component in the concave portion of the carrier tape may jump out of the concave portion due to the acceleration/deceleration of the conveying mechanism. Therefore, in the electronic component supply device disclosed in Japanese Patent Application Laid-Open No. 2012-18999, it is difficult to increase the transport speed of the component supply tape by the transport mechanism in order to prevent the electronic components from popping out. Here, if it is difficult to increase the transport speed of the component supply tape by the transport mechanism, it becomes difficult to shorten the time until the components are mounted on the board. For this reason, conventionally, it has been desired to reduce the time required to mount an electronic component (component) on a substrate (improve productivity) while preventing the electronic component (component) from popping out.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and one object of the present invention is to reduce the time required to mount a component on a board while suppressing the component from popping out (improve productivity). It is an object of the present invention to provide a component feeding device and a component mounting device capable of realizing (improvement of the above).

A feeder control is provided that is configured to initiate control to cause the As a result, the cover tape can be wound by the tape winding section near the suction position, so that the attached state of the cover tape can be maintained up to the vicinity of the suction position. Therefore, it is possible to prevent the component from jumping out until the component reaches the pick-up position, so that the tape feeding speed of the component supply tape by the tape feeding section can be increased. As a result, it is possible to reduce the time required to mount the component on the board (improve productivity) while preventing the component from popping out.

In the component supply device according to the first aspect, preferably, the feeder control unit stops the components stored in the storage unit in accordance with the suction position after the component supply tape fed by the tape feed unit starts to decelerate. or after stopping the storage portion in accordance with the suction position, the control for exposing the component is started by winding the cover tape by the tape winding portion. With this configuration, the winding of the cover tape can be started avoiding the time when the feeding speed of the component supply tape fed by the tape feeder is switched to deceleration, so the acceleration/deceleration by the tape feeder is stabilized. From this state, the cover tape can be wound by the tape winding section. As a result, it is possible to more reliably prevent the component from jumping out until the component reaches the pick-up position while improving the feeding speed of the component supply tape.

Even when at least part of the cover tape winding operation is performed, it is possible to suppress a delay in the component supply operation due to the winding of the cover tape by the tape winding unit near the suction position.

In the component supply device according to the first aspect, preferably, the feeder control section causes the tape winding section to wind up the cover tape before deceleration of the component supply tape fed by the tape feeding section is started. Part of the cover tape at the opening of the tape is peeled off, and after the deceleration of the component supply tape fed by the tape feeding unit is started, the tape winding unit further winds up the cover tape to expose the component. is configured to start With this configuration, it is possible to reduce the amount of cover tape wound by the winding motor near the suction position. Delays in supply work can be suppressed.

Specifically, as shown in FIG. 8, the feeder control unit 25 causes the component supply tape 101 fed by the tape feeding unit 22 to be stored in the component storage unit 111a in accordance with the suction position 102 after the deceleration of the component supply tape 101 is started. Before stopping the electronic component E, the cover tape 112 is wound up by the tape winding unit 23 based on the fact that the feeding motor 22b is decelerated to a predetermined rotation speed Rt or less corresponding to the predetermined speed. It is configured to initiate control to expose E. Here, the rotation speed of the feed motor 22b is calculated by differentiating the rotation angle of the feed motor 22b measured by the feed rotation angle sensor 22d in the feeder control section 25. FIG.

8 and 9, the feeder control unit 25 causes the tape winding unit 23 to wind the cover tape 112 at once after the deceleration of the component supply tape 101 fed by the tape feeding unit 22 is started. configured to control.

That is, the feeder control unit 25 causes the tape winding unit 23 to wind the cover tape 112 when the tape winding unit 23 winds the cover tape 112 after deceleration of the component supply tape 101 fed by the tape feeding unit 22 is started. It is configured to perform control so that the maximum speed of the cover tape 112 is higher than the maximum speed of the component supply tape 101 fed by the tape feeder 22 . Specifically, the feeder control unit 25 causes the tape winding unit 23 to take up The tape feeding unit 22 controls the maximum rotational speed Mv1 of the winding motor 23c for winding the component supply tape 101 to be higher than the maximum rotational speed Mv2 of the feeding motor 22b for feeding the component supply tape 101. there is

Here, the gear ratio of the driving force transmission mechanism 23d of the tape winding section 23 and the gear ratio of the driving force transmission mechanism 22c of the tape feeding section 22 are such that the maximum rotational speed Mv1 of the winding motor 23c is equal to that of the feeding motor 22b. so that the maximum speed of the cover tape 112 wound by the tape winder 23 is greater than the maximum speed of the component supply tape 101 fed by the tape feeder 22, adjusted.

As shown in FIGS. 8 and 10, the feeder control unit 25 causes the winding amount D2 of the cover tape 112 by the tape winding unit 23 to follow the feeding amount D1 of the component supply tape 101 of the tape feeding unit 22. is configured to perform control for exposing the electronic component E. That is, the feeder control section 25 is configured to perform control so that the feed amount D1 and the take-up amount D2 are approximately matched. The feeder control unit 25 is configured to end control for exposing the electronic component E when the feeding amount D1 and the winding amount D2 substantially match. Here, the control for exposing the electronic component E is completed at time T2 after the time Tc at which the electronic component E is sent to the pickup position 102 by the tape feeding section 22 .

As shown in FIG. 11, in the component mounting apparatus 10, when the cover tape 112 is taken up at once while the component supply tape 101 is being decelerated by the tape feeder 22, the electronic component E is placed inside the driving force transmission mechanism 22c by the backlash. stop position 103 may be located on the tape feeding direction D side from the suction position 102 . That is, in a state where the component supply tape 101 is held down by the tape holding portion 24, the force Rf for winding the cover tape 112 by the tape winding portion 23 causes the tape feeding direction generated with the tape supporting portion 24a of the tape holding portion 24 as a fulcrum. Due to the force Sf of D, the carrier tape 111 moves by the backlash. Here, the winding amount D2 of the cover tape 112 is set larger than the pitch between the plurality of component storage portions 111a.

In order to eliminate the deviation caused by backlash, the feeder control unit 25 causes the tape holding unit 24 to hold down the component supply tape 101 while the tape winding unit 23 winds up the cover tape 112 . Based on the suction position 102 preset by adding the movement of the backlash of the carrier tape 111 due to the force Sf in the tape feeding direction D generated with the support portion 24a as a fulcrum, the component is moved to the suction position 102 by the tape feeding portion 22. It is configured to control feeding of the supply tape 101 . Specifically, the feeder control unit 25 is configured to perform control to preliminarily add the same offset value to the rotation control amount set for each of the plurality of pins Pn of the sprocket 22a.

(Flowchart of cover tape winding process)
The cover tape winding process by the feeder control unit 25 will be described below with reference to FIG. 12 . The cover tape winding process is a process of winding the cover tape 112 just before the suction position 102 .

In step S1, the feeding of the component supply tape 101 by the tape feeding section 22 is started by the feeder control section 25. In step S2, the feeder control section 25 determines whether or not the rotation speed of the feeding motor 22b of the tape feeding section 22 has become equal to or less than a predetermined rotation speed Rt. If the rotation speed of the feed motor 22b is equal to or less than the predetermined rotation speed Rt, the process proceeds to step S3, and if the rotation speed of the feed motor 22b exceeds the predetermined rotation speed Rt, step S2 is repeated.

In step S3, the feeder control unit 25 causes the tape winding unit 23 to start winding the cover tape 112. In step S4, the feeder control section 25 determines whether or not the feeding amount D1 by the tape feeding section 22 and the winding amount D2 by the tape winding section 23 substantially match. If the feeding amount D1 and the winding amount D2 substantially match, the cover tape winding process is terminated. If the feeding amount D1 and the winding amount D2 do not substantially match, step S4 is repeated.

(Effect of the first embodiment)
The following effects can be obtained in the first embodiment.

In the first embodiment, as described above, the tape feeder 2a winds the cover tape 112 by the tape winder 23 after the deceleration of the component supply tape 101 fed by the tape feeder 22 is started. It includes a feeder control 25 configured to initiate controls for exposing part E. As a result, the cover tape 112 can be wound by the tape winding unit 23 near the suction position 102 , so that the attached state of the cover tape 112 can be maintained up to the vicinity of the suction position 102 . Therefore, it is possible to prevent the electronic component E from jumping out until the electronic component E reaches the suction position 102, so that the tape feeding speed of the component supply tape 101 by the tape feeding section 22 can be increased. As a result, it is possible to shorten the time until the electronic component E is mounted on the board B (improve productivity) while suppressing the electronic component E from popping out. Moreover, not only magnetic components such as chip resistors whose protrusion can be suppressed by the magnet 21 but also non-magnetic components whose protrusion cannot be suppressed by the magnet 21 can be suppressed. As a result, tape feed speeds for both magnetic and non-magnetic components can be increased. Moreover, since it is possible to prevent both the magnetic parts and the non-magnetic parts from jumping out, the magnet 21 can be eliminated from the tape feeder 2a.

Further, in the first embodiment, as described above, after the component supply tape 101 fed by the tape feeding unit 22 starts decelerating, the feeder control unit 25 accommodates the component supply tape 101 in the component storage unit 111a in accordance with the suction position 102. Before the electronic component E is stopped, the tape winder 23 winds up the cover tape 112 to start the control of exposing the electronic component E. As a result, the winding of the cover tape 112 can be started by avoiding the point in time when the feeding speed of the component supply tape 101 fed by the tape feeder 22 is switched to deceleration, so that the acceleration/deceleration by the tape feeder 22 is stabilized. From this state, the cover tape 112 can be wound by the tape winding section 23 . As a result, it is possible to more reliably prevent the electronic component E from jumping out until the electronic component E reaches the pickup position 102 while increasing the feeding speed of the component supply tape 101 .

When the feeding speed of the component supply tape 101 fed by the tape feeder 22 is reduced to a predetermined speed or less before stopping the electronic component E, the tape winder 23 winds up the cover tape 112. It is configured to initiate control for exposing the electronic component E. As a result, the winding of the cover tape 112 can be started avoiding the time when the feeding speed of the component supply tape 101 fed by the tape feeder 22 is switched to deceleration, so that the acceleration/deceleration by the tape feeder 22 is ensured. The cover tape 112 can be wound by the tape winding section 23 in a calm state. As a result, it is possible to more reliably prevent the electronic component E from jumping out until the electronic component E reaches the pickup position 102 .

When the motor 22b is decelerated to a predetermined rotation speed Rt or less corresponding to the predetermined speed, the tape winder 23 winds up the cover tape 112 to start the control of exposing the electronic component E. ing. Thus, by directly using the rotation speed of the feeding motor 22b to start the control of winding the cover tape 112 by the tape winding section 23, the timing at which the acceleration/deceleration by the tape feeding section 22 has stabilized can be obtained accurately. Therefore, the winding control of the cover tape 112 can be started at an appropriate timing.

Further, in the first embodiment, as described above, the feeder control unit 25 causes the tape winding unit 23 to wind the cover tape 112 after deceleration of the component supply tape 101 fed by the tape feeding unit 22 is started. At this time, control is performed so that the maximum speed of the cover tape 112 wound by the tape winder 23 is higher than the maximum speed of the component supply tape 101 fed by the tape feeder 22 . As a result, the feed amount D1 of the component supply tape 101 by the feed motor 22b and the winding amount D2 of the cover tape 112 by the winding motor 23c can be brought into agreement at an early stage. Even when at least a part of the work of winding the cover tape 112 is performed after the work has been done, the delay in the work of supplying the parts due to the winding of the cover tape 112 by the tape winding part 23 near the suction position 102 is suppressed. be able to.

The feeder control unit 25 controls the tape holding unit 24 to hold down the component supply tape 101 and the tape winding unit 23 to wind the cover tape 112. The feeder control unit 25 controls the tape support unit 24a of the tape holding unit 24 as a fulcrum. Based on the suction position 102 set in advance by adding the movement of the carrier tape 111 by the force in the feeding direction D, the tape feeding unit 22 controls the feeding of the component supply tape 101 to the suction position 102. It is configured. As a result, the tape feeder 22 can feed the electronic component E to the pickup position 102 without positional deviation, so that the electronic component E can be more reliably fed to a position where it can be picked up in a more stable state.

Further, in the first embodiment, as described above, the tape support portion 24a of the tape feeder 2a is arranged in the vicinity of the suction position 102 on the upstream side in the tape feeding direction D, and the tape holding portion for holding down the component supply tape 101 is provided. A portion 24 is provided. The feeder control unit 25 is configured to perform control for exposing the electronic component E by winding the cover tape 112 by the tape winding unit 23 on the suction position 102 side of the tape supporting unit 24a of the tape pressing unit 24. there is As a result, the cover tape 112 can be wound by the tape winding unit 23 at a position closer to the suction position 102, so that the electronic component E can be more reliably protruded until the electronic component E reaches the suction position 102. can be suppressed.

In addition, in the above-described first to third embodiments, the feeder control unit 25 (225, 325) causes the component supply tape 101 fed by the tape feeding unit 22 to start decelerating, and then adjusts the component supply tape 101 to the pickup position 102 to store the component. When the feeding speed of the component supply tape 101 fed by the tape feeder 22 is reduced to a predetermined rotational speed Rt or less before the electronic components E housed in the portion 111a are stopped, the tape winder 23 rolls the cover tape. Although an example is shown in which control for exposing the electronic component E is started by winding up the wire 112, the present invention is not limited to this. In the present invention, the feeder control section controls the tape winding section to wind up the cover tape to expose the components when a predetermined time elapses after the deceleration of the component supply tape fed by the tape feeding section is started. may be configured to initiate

Further, in the above-described third embodiment, an example is shown in which the amount of peeling D21 before the start of deceleration is smaller than the amount of peeling D22 after the start of deceleration, but the present invention is not limited to this. In the present invention, the peeling amount before the start of deceleration and the peeling amount after the start of deceleration may be substantially the same.

In the first to third embodiments, the feeder control unit 25 (225, 325) sucks the tape feed unit 22 based on the suction position 102 preset by adding the movement of the backlash of the carrier tape 111. Although an example configured to control feeding of the component supply tape 101 to the position 102 has been shown, the present invention is not limited to this. In the present invention, the feeder control section may be configured to perform control so that the tape feeding section returns the component supply tape by the amount of play without adding the movement of the carrier tape by the amount of play to the pickup position.

In addition, in the above-described first to third embodiments, the feeder control section 25 (225, 325) causes the tape winding section 23 to start decelerating the component supply tape 101 fed by the tape feeding section 22, and then the cover tape. 112, the maximum rotational speed Mv1 of the winding motor 23c for winding the cover tape 112 by the tape winding section 23 is calculated from the maximum rotational speed Mv2 of the feeding motor 22b for feeding the component supply tape 101 by the tape feeding section 22. Although an example is shown in which control is performed so as to increase , the present invention is not limited to this. In the present invention, even if the maximum rotation speed of the winding motor is lower than the maximum rotation speed of the feeding motor, the gear ratio of the driving force transmission mechanism of the tape winding section and the gear of the driving force transmission mechanism of the tape feeding section By adjusting the ratio, the maximum speed of the cover tape wound by the tape winder should be higher than the maximum speed of the component supply tape fed by the tape feeder.

Further, in the above-described first to third embodiments, for convenience of explanation, the control processing of the feeder control unit 25 (225, 325) has been explained using a flow-driven flowchart in which processing is performed in order along the processing flow. Although provided by way of example, the invention is not so limited. In the present invention, the control processing of the feeder control section may be performed by event-driven processing that executes processing on an event-by-event basis. In this case, it may be completely event-driven, or a combination of event-driven and flow-driven.
