Description

  The present invention relates to a tape collecting mechanism, a tape feeder, a mounting apparatus, and a tape collecting method for collecting a tape by a driving force of a motor.

  In general, as a tape collecting mechanism used for various devices, one that collects a tape while suppressing slack of the tape is known (for example, see Patent Document 1). In the tape recovery mechanism described in Patent Document 1, an adjustment mechanism such as a tension roller is provided in the tape transport path, and a tensile force is generated in a direction opposite to the tape recovery direction by this adjustment mechanism. A certain tension is applied to the. Since the tension continues to act on the tape even when the motor of the tape recovery mechanism is stopped, the reverse rotation of the motor is suppressed by applying a braking force by weakly exciting the motor.

JP 2012-018999 A

  However, the general tape recovery mechanism as described above has a problem that the power consumption and the heat generation amount are increased because the weak excitation must be continuously applied even when the motor is stopped. On the other hand, when the weak excitation of the motor is cut off, there is a problem in that the motor reverses without being able to withstand the tensile force of the tape and loses synchronization with the input signal.

  The present invention has been made in view of the above points, and provides a tape recovery mechanism, a tape feeder, a mounting device, and a tape recovery method capable of preventing the motor from stepping out while keeping power consumption and heat generation low. This is one of the purposes.

  A tape recovery mechanism according to an aspect of the present invention is a tape recovery mechanism that recovers a tape fed from a supply source, and includes a roller that sends the tape in a recovery direction, and a motor connected to the roller. Before the excitation is cut off, the motor rotates by a predetermined amount in a direction opposite to that when the tape is collected.

  A tape recovery method according to an aspect of the present invention is a tape recovery method for recovering a tape fed from a supply source, the step of recovering the tape with a roller coupled to the motor by exciting the motor; Before the excitation is cut off, the motor has a step of rotating by a predetermined amount in a direction opposite to that when collecting the tape.

  According to these configurations, the motor is stopped in a state in which the tape is slackened by rotating the motor by a predetermined amount in the direction opposite to that at the time of collecting the tape before turning off the excitation of the motor. Since the tape tension is released, it does not reverse even if the motor is de-energized. Accordingly, since the motor is not excited when the motor is stopped, the power consumption and the heat generation amount can be kept low, and the reverse rotation of the motor can be suppressed to prevent the step-out.

  In the tape collecting mechanism of one aspect of the present invention, the motor is excited before the tape is collected, and is maintained in a stopped state after the motor has rotated a predetermined amount in the forward direction. According to this configuration, when the motor rotates by a predetermined amount in the forward direction, the tape can be re-stretched to prepare for the tape collecting operation.

  A tape feeder according to an aspect of the present invention includes the tape recovery mechanism described above, and causes the tape recovery mechanism to recover a cover tape peeled off from a carrier tape in which a large number of parts are packaged. It feeds out toward the supply position. According to this configuration, it is possible to stably supply components by the tape feeder by suppressing power consumption and heat generation of the motor to a low level and preventing step-out.

  In the tape feeder according to one aspect of the present invention, the motor is excited a predetermined time before the start of supply of parts scheduled in the operation schedule, and is maintained in a stopped state after the motor has rotated a predetermined amount in the forward direction. The According to this configuration, since the tape is re-stretched based on the operation schedule, the component supply operation is not delayed by the re-stretching operation time. Therefore, the re-stretching of the tape does not affect the component supply operation, and a reduction in the tact time during component supply can be suppressed. Further, by suppressing an increase in the excitation time of the motor, the power consumption and the heat generation amount can be kept low.

  In the tape feeder according to one aspect of the present invention, the motor is excited during a waiting time when parts are supplied, and the motor is maintained in a stopped state after rotating by a predetermined amount in the forward direction. According to this configuration, since the tape is re-stretched using the waiting time for supplying the component, the operation of supplying the component is not delayed by the operation time for re-stretching the tape. Therefore, the re-stretching of the tape does not affect the component supply operation, and a reduction in the tact time during component supply can be suppressed. Further, by suppressing an increase in the excitation time of the motor, the power consumption and the heat generation amount can be kept low.

  A mounting apparatus according to an aspect of the present invention includes the above-described tape feeder and a mounting head for mounting a component fed from the tape feeder on a substrate. According to this configuration, the mounting head can stably receive components from the tape feeder and mount them on the substrate while keeping the power consumption and heat generation amount of the tape feeder low.

  According to the present invention, before the motor is de-energized, the motor rotates by a predetermined amount in the direction opposite to the time when the tape is collected, thereby preventing the motor from stepping out while keeping power consumption and heat generation low. it can.

  Hereinafter, the mounting apparatus of the present embodiment will be described with reference to the accompanying drawings. FIG. 1 is a schematic diagram showing the entire mounting apparatus of the present embodiment. FIG. 2 is a schematic diagram showing the tape feeder of the present embodiment. In addition, the mounting apparatus of this Embodiment is only an example, and can be changed suitably.

  As shown in FIG. 1, the mounting apparatus 1 is configured to mount various components supplied by the tape feeder 20 at predetermined positions on the substrate W by the mounting head 12. A substrate transport unit 11 that transports the substrate W in the X-axis direction is disposed on the base 10 of the mounting apparatus 1. The board transport unit 11 loads and positions the board W before component mounting from one end side in the X-axis direction below the mounting head 12, and moves the board W after component mounting from the other end side in the X-axis direction to the outside of the apparatus. I am carrying it out. A feeder bank 19 in which a plurality of tape feeders 20 are arranged side by side in the X-axis direction is detachably connected to both sides of the substrate transport unit 11.

  A tape reel (supplier) 21 is detachably mounted on the tape feeder 20, and a carrier tape 22 (see FIG. 2) in which a large number of components are packaged is wound around the tape reel 21. In the tape feeder 20, the carrier tape 22 is conveyed toward the supply position picked up by the mounting head 12 by the rotation of the sprocket wheel 31 (see FIG. 2). At the supply position for the mounting head 12, the cover tape 23 (see FIG. 2) on the surface is peeled from the carrier tape 22, and the components in the pocket of the carrier tape 22 are exposed to the outside. The components are not particularly limited to electronic components as long as they can be mounted on the substrate W.

  On the base 10, a moving mechanism 13 that horizontally moves the pair of mounting heads 12 in the X-axis direction and the Y-axis direction is provided. The moving mechanism 13 has a pair of Y-axis drive units 14 extending in the Y-axis direction and an X-axis drive unit 15 extending in the X-axis direction. The pair of Y-axis drive units 14 are supported by support units (not shown) provided upright at the four corners of the base 10, and the X-axis drive unit 15 is movable to the pair of Y-axis drive units 14 in the Y-axis direction. is set up. The mounting head 12 is installed on the X-axis drive unit 15 so as to be movable in the X-axis direction. The mounting head 12 is horizontally moved by the X-axis drive unit 15 and the Y-axis drive unit 14 and picked up from the tape feeder 20. The finished component is mounted at a desired position on the substrate W.

  As shown in FIG. 2, the tape feeder 20 is configured to peel the cover tape 23 from the carrier tape 22 and send out the parts exposed from the carrier tape 22 toward the supply position for the mounting head 12 (see FIG. 1). ing. An opening 24 is provided in the lower part on the rear side of the feeder frame 25, and the carrier tape 22 fed out from the tape reel 21 (see FIG. 1) is inserted into the opening 24, along the conveyance guide 26 in the feeder frame 25. The carrier tape 22 has been sent out. The carrier tape 22 is guided obliquely upward from the opening 24 of the feeder frame 25 by the conveyance guide 26 and then guided forward along the upper surface of the feeder frame 25.

  An upper cover 27 that covers the carrier tape 22 from above is attached to the front side of the feeder frame 25. A slit 28 is formed in the upper cover 27, the cover tape 23 peeled off from the carrier tape 22 is folded back through the slit 28, and the carrier tape 22 from which the cover tape 23 has been peeled is moved forward in the upper cover 27. It is conveyed toward. A supply port 29 is formed in front of the slit 28 in the upper cover 27, and the components in the pocket of the carrier tape 22 are exposed through the supply port 29. Components exposed from the supply port 29 are delivered to the nozzle 17 of the mounting head 12.

  A sprocket wheel 31 that feeds the carrier tape 22 forward is supported on the front side of the feeder frame 25. A feed motor 33 is connected to the sprocket wheel 31 via a reduction gear train 32. When the sprocket wheel 31 is interlocked with the rotation of the feed motor 33, the carrier tape 22 is fed forward by the sprocket wheel 31 and the components are sequentially supplied toward the supply port 29. After the cover tape 23 peeled off from the carrier tape 22 is folded back, it is fed into a collection box 47 on the rear side of the feeder frame 25 by a guide roller 41, a tension roller 42, and a pair of collection rollers (rollers) 44. Yes.

  A pair of collection rollers 44 that feed the cover tape 23 in the collection direction are supported near the entrance of the collection box 47. A pull motor (motor) 46 is connected to the collection roller 44 via a reduction gear train 45. When the collection roller 44 is interlocked with the rotation of the pull motor 46, the cover tape 23 is sent backward by the collection roller 44 and collected in the collection box 47. A tension roller 42 supported by the tip of the tension arm 43 is positioned in front of the pair of collection rollers 44. When the cover tape 23 is pushed in by the tension roller 42, the cover tape 23 is collected in a state where the tension is applied.

  Thus, by recovering the cover tape 23 while applying a certain tension with the tension roller 42, the cover tape 23 is favorably peeled from the carrier tape 22 when the carrier tape 22 is sent out. The tape feeder 20 is provided with a control circuit 49, and a feed motor 33 and a pull motor 46 are connected to the control circuit 49. The control circuit 49 is communicably connected to the mounting apparatus 1 (see FIG. 1) via a communication connector. When the control circuit 49 receives a control command from the mounting apparatus 1, the excitation timing of the feed motor 33 and the pull motor 46 is detected. Is controlled.

The control circuit 49 includes a processor, a memory, and the like that control various motors. The memory is composed of one or a plurality of storage media such as a ROM (Read Only Memory) and a RAM (Random Access Memory) depending on the application, and stores a control program for controlling various motors. The feed motor 33 and the pull motor 46 may be provided with an encoder that detects the rotation amount of each motor. Since the detection result of the encoder is fed back to each motor, the amount of tape fed by each motor can be accurately controlled.

  By the way, in the tape feeder 20, the gear ratio of the pull motor 46 is set so small that the operator can pull the cover tape 23 manually so that setup can be performed with the power off. Since tension continues to be applied to the cover tape 23 by the tension roller 42 even when the power is turned off, the pull motor 46 is normally weakly excited to suppress reverse rotation of the pull motor 46 due to the tensile force of the cover tape 23. However, weak excitation must always be applied to the pull motor 46, and there is a problem that the power consumption and heat generation amount of the pull motor 46 increase.

  Therefore, in the tape collecting mechanism 40 of the present embodiment, before the pull motor 46 is de-energized, the pull motor 46 rotates by a predetermined amount in the direction opposite to that when the cover tape 23 is collected, thereby loosening the cover tape 23. Thereby, the step-out due to the reverse rotation of the pull motor 46 can be prevented while keeping the power consumption and the heat generation amount of the pull motor 46 low. Further, in order to resume the feeding of the carrier tape 22, it is necessary to re-stretch the cover tape 23. However, the cover tape 23 can be re-covered by completing the re-stretching of the cover tape 23 shortly before the parts supply operation is instructed. The feeding operation of the tape feeder 20 is not delayed by the re-stretching of the tape 23.

  Hereinafter, with reference to FIG. 3 and FIG. 4, a component supply operation by the tape feeder of the present embodiment will be described. FIG. 3 is a diagram illustrating an example of a component supply operation according to the present embodiment. FIG. 4 is a diagram illustrating an example of motor control according to the present embodiment. Note that each time of motor control in FIG. 4 is not particularly limited, and is appropriately changed according to the control program. Further, in FIG. 4, description will be made using the reference numerals in FIG.

  As shown in FIG. 3A, during a component supply operation, a control command for the supply operation is output to the feed motor 33 and the pull motor 46 through the control circuit 49. The feed motor 33 intermittently feeds the carrier tape 22 by the sprocket wheel 31 according to the control command, and sends parts to the supply port 29 by the carrier tape 22 in order. The pull motor 46 sends the cover tape 23 peeled off from the carrier tape 22 to the collection box 47 by the pair of collection rollers 44 at the same feed amount as the carrier motor 22 in synchronization with the feed motor 33 according to the control command. .

  At this time, since the cover tape 23 is stretched by the tension roller 42, the pulling force of the collection roller 44 acts strongly on the cover tape 23 at the peeling position where the cover tape 23 is peeled from the carrier tape 22. Since the carrier tape 22 is strongly fed to the front side of the tape feeder 20 and the cover tape 23 is strongly pulled in while being folded back to the rear side of the tape feeder 20, the cover tape 23 is easily peeled off from the carrier tape 22. For this reason, the cover tape 23 is not peeled off from the carrier tape 22 and the cover tape 23 is not wound on the supply port 29 side of the tape feeder 20.

  As shown in FIG. 3B, when the carrier tape 22 is stopped, a control command for turning off the excitation is output to the feed motor 33 and the pull motor 46 through the control circuit 49. The feed motor 33 starts to de-energize according to the control command, and the feed of the carrier tape 22 is stopped when the rotation of the sprocket wheel 31 is stopped. The pull motor 46 rotates by a predetermined amount in the direction opposite to that when the cover tape 23 is collected before the excitation is turned off according to the control command. The collection roller 44 is reversely rotated by the pull motor 46 and the cover tape 23 is sent out from the collection box 47, whereby the tension applied to the cover tape 23 is released.

  Then, the pull motor 46 starts to turn off the excitation, and the reverse rotation of the collecting roller 44 is stopped, so that the feed of the cover tape 23 is stopped. Since the cover tape 23 is slack, the pulling force is not exerted on the pull motor 46 by the cover tape 23. Therefore, even if no excitation is applied to the pull motor 46, the stop state can be maintained by the mechanical load torque of the pull motor 46, and the power consumption and heat generation amount of the pull motor 46 do not increase. Further, since the reverse rotation of the pull motor 46 is prevented, the synchronization with respect to the control command is not lost, and the pull motor 46 does not become uncontrollable due to step-out.

  Thus, the pull motor 46 is stopped in a state that can be controlled by the next recovery operation of the cover tape 23 by releasing the tension of the cover tape 23 by intentionally reversing before the excitation is cut off. It should be noted that the predetermined amount when the pull motor 46 rotates in the direction opposite to that when the cover tape 23 is recovered may be a rotation amount at least so that the tensile force of the cover tape 23 becomes smaller than the load torque of the pull motor 46. Therefore, it is not necessary that the cover tape 23 is completely loosened by the reverse rotation of the pull motor 46, and a slight tensile force may be applied to the pull motor 46 by the cover tape 23.

  As shown in FIG. 3C, when supply of components is resumed, a control command for starting supply preparation is output from the control circuit 49 to the pull motor 46 before the control command for supply operation is output from the control circuit 49. The pull motor 46 is energized before the cover tape 23 is collected according to the control command, and rotates by a predetermined amount in the same forward direction as the cover tape 23 is collected. The collection roller 44 is rotated forward by the pull motor 46 and the cover tape 23 is fed into the collection box 47, so that the slack is removed from the cover tape 23 and the cover tape 23 is re-tensioned.

  After the pull motor 46 is rotated by a predetermined amount by the excitation of the pull motor 46, the pull motor 46 is maintained in a stopped state. At this time, the cover tape 23 is re-stretched, but since the braking force is applied to the pull motor 46 by excitation, the pull motor 46 is not reversed by the tensile force of the cover tape 23. Then, the control command for the supply operation is again output to the feed motor 33 and the pull motor 46 through the control circuit 49, and the feed operation of the carrier tape 22 and the recovery operation of the cover tape 23 are performed. As described above, when the pull motor 46 rotates in the forward direction by a predetermined amount, the cover tape 23 is re-stretched to prepare for the tape collecting operation.

  In this case, the re-covering of the cover tape 23 is completed shortly before the feeding operation of the carrier tape 22 is started. For example, since the mounting apparatus 1 (see FIG. 1) operates based on the operation schedule, the pull motor 46 is excited a predetermined time before the feeding operation of the carrier tape 22 scheduled in the operation schedule, and the pull motor 46 is sequentially operated. After being rotated a predetermined amount in the direction, it is maintained in a stopped state. Further, the pull motor 46 is excited during the waiting time when the tape feeder 20 supplies parts to the mounting head 12 (see FIG. 1), and the pull motor 46 is maintained in a stopped state after rotating by a predetermined amount in the forward direction. Good.

  As shown in FIG. 4, a control command for starting supply preparation from the mounting apparatus 1 (see FIG. 1) to the pull motor 46 of the tape feeder 20 at least 50 ms before the start of the component supply operation based on the operation schedule. Will be notified. The pull motor 46 returns a status response to the mounting apparatus 1, and the pull motor 46 is excited and preparation for supply is started. At this time, after 2 [ms] has elapsed due to current increase, the cover tape 23 is re-stretched from 50 [ms] to 210 [ms]. In this way, preparation for the recovery operation of the cover tape 23 by the pull motor 46 is made before the component supply operation.

  After more than 50 [ms] has elapsed from the start of the re-stretching, the mounting apparatus 1 notifies the feed motor 33 and the pull motor 46 of a control command for the supply operation. After the current up 2 [ms] has elapsed, the feed motor 33 sends out the carrier tape 22 and returns a status response to the mounting apparatus 1. The pull motor 46 waits for the current up of the feed motor 33, collects the cover tape 23, and returns a status response to the mounting apparatus 1. The feed operation of the feed motor 33 and the recovery operation of the pull motor 46 are synchronized, and the interval from the command reception to the response return is set to 60 [ms], for example.

  Since the re-covering of the cover tape 23 is performed at least 50 [ms] before the feeding operation of the carrier tape 22, the collection operation of the pull motor 46 is prepared when the feeding operation is performed by the feed motor 33. Yes. In addition, since the excitation time of the pull motor 46 is only slightly increased, the increase in the excitation time of the pull motor 46 can be suppressed short, and the power consumption and heat generation amount of the pull motor 46 can be kept low. Furthermore, since the cover tape 23 is re-stretched by effectively using the standby time during which the component supply operation is not performed based on the operation schedule, the component supply operation is not delayed by the re-stretching operation time of the cover tape 23.

  When the component supply operation is repeated a plurality of times and a plurality of components are supplied to the mounting head 12, a control command for completion of supply preparation is notified from the mounting apparatus 1 to the feed motor 33 and the pull motor 46. The feed motor 33 returns a status response to the mounting apparatus 1, and the excitation is turned off after 100 [ms] has elapsed. The pull motor 46 is turned off after 100 [ms] has elapsed after the cover tape 23 has been loosened over 45 [ms] via the status response to the mounting device 1. Since the cover tape 23 is slack, it does not reverse even when the excitation of the pull motor 46 is cut off.

  Further, when the mounting head 12 mounts a component on the board and returns the component to the tape feeder 20 again, the cover tape is utilized by using a waiting time when the component is supplied from the tape feeder 20 to the mounting head 12. 23 is re-stretched. Also in this case, similarly to the above, the cover tape 23 is re-stretched by the pull motor 46 50 ms or more before the start of the feeding operation of the carrier tape 22 to prepare for the recovery operation of the cover tape 23. By utilizing the idle time before the component supply operation, the re-covering of the cover tape 23 does not affect the component supply operation, and the reduction in the tact time during component supply can be suppressed.

  As described above, in the tape collecting mechanism 40 according to the present embodiment, the pull motor 46 rotates by a predetermined amount in the direction opposite to that when the cover tape 23 is collected before the excitation of the pull motor 46, so that the cover tape 23 is loosened. The pull motor 46 is stopped in a state where the Since the tension of the cover tape 23 is released, it does not reverse even if the excitation of the pull motor 46 is turned off. Therefore, since the excitation is not performed when the pull motor 46 is stopped, the power consumption and the heat generation amount can be kept low, and the reverse rotation of the pull motor 46 can be suppressed to prevent the step-out.

  In addition, in this Embodiment, although the structure which applied the tape collection | recovery mechanism to the tape feeder was demonstrated, it is not limited to this structure. The tape recovery mechanism only needs to recover the tape fed from the supply source, and can be applied to various processing apparatuses in which tape conveyance is performed.

  In the present embodiment, the tape collecting mechanism is applied to the configuration of collecting the cover tape by controlling the pull motor of the tape feeder. However, the tape collecting mechanism is applied to the configuration of collecting the carrier tape by controlling the feed motor of the tape feeder. Also good.

  In the present embodiment, the collecting roller may be configured to feed the tape in the collecting direction. For example, the outer circumferential surface may be a friction surface, or feed teeth may be formed on the outer circumferential surface. Good.

  Moreover, in this Embodiment, although the suction nozzle was illustrated as a nozzle, it is not limited to this structure. The nozzle is not particularly limited as long as it can hold a component, and may be, for example, a gripper nozzle.

  In the present embodiment, the substrate is not limited to a printed circuit board as long as various components can be mounted, and may be a flexible substrate placed on a jig substrate.

  Moreover, the program of this Embodiment may be memorize | stored in a storage medium. The recording medium is not particularly limited, but may be a non-transitory recording medium such as an optical disk, a magneto-optical disk, or a flash memory.

  Moreover, although embodiment and modification of this invention were demonstrated, what combined the said embodiment and modification as the other embodiment of this invention entirely or partially may be sufficient.

  The embodiments of the present invention are not limited to the above-described embodiments and modifications, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea of the present invention. Furthermore, if the technical idea of the present invention can be realized in another way by technological advancement or another derived technique, the method may be used. Accordingly, the claims cover all embodiments that can be included within the scope of the technical idea of the present invention.

  Further, in the above-described embodiment, the tape collecting mechanism collects the tape fed from the supply source, and includes a collecting roller for feeding the tape in the collecting direction and a motor connected to the collecting roller, before the motor is de-energized. Further, the motor rotates by a predetermined amount in a direction opposite to that at the time of collecting the tape. According to this configuration, the motor is stopped in a state in which the tape is slackened by rotating the motor by a predetermined amount in the direction opposite to that at the time of collecting the tape before the motor is de-energized. Since the tape tension is released, it does not reverse even if the motor is de-energized. Accordingly, since the motor is not excited when the motor is stopped, the power consumption and the heat generation amount can be kept low, and the reverse rotation of the motor can be suppressed to prevent the step-out.

  As described above, the present invention has an effect of preventing the motor from stepping out while keeping power consumption and heat generation low, and in particular, a tape that collects the cover tape peeled off from the carrier tape. It is useful for collection mechanisms, tape feeders, mounting devices, and tape collection methods.
