technical field

The present invention relates to a tape recovery mechanism, a tape feeder, a mounting device, and a tape recovery method for recovering a tape by the driving force of a motor.

Background technique

Generally, as a belt recovery mechanism used in various equipments, a belt recovery mechanism for recovering a belt while suppressing slack of the belt is known (for example, refer to Patent Document 1). In the belt recovery mechanism described in Patent Document 1, an adjustment mechanism such as a tension roller is provided in the conveying path of the belt, and the adjustment mechanism generates a tensile force in a direction opposite to the belt recovery direction, and a constant tension is applied to the belt. tight. Since the tension force continues to act on the belt even when the electric motor of the belt retracting mechanism is stopped, the electric motor is weakly excited to apply a braking force, thereby suppressing the reverse rotation of the electric motor.

Patent Document 1: Japanese Patent Laid-Open No. 2012-018999

However, in the above-described normal belt recovery mechanism, the field weakening must be continuously performed even when the motor is stopped, so there is a problem that power consumption and heat generation increase. On the other hand, when the weak excitation of the motor is cut off, there is a problem in that the motor reverses direction due to the unbearable tensile force of the belt, and the synchronization with the input signal is lost, that is, the so-called out-of-balance, and the motor runs out of control.

SUMMARY OF THE INVENTION

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a belt recovery mechanism, a belt feeder, a mounting device, and a belt recovery method capable of reducing power consumption and heat generation and preventing the motor from becoming out of step. .

According to one aspect of the present invention, a tape recovery mechanism for recovering a tape drawn out from a supply source is characterized by comprising: a roller for conveying the tape in a recovery direction; and a motor coupled to the roller. , before the excitation of the motor is cut off, the motor is rotated by a predetermined amount in a direction opposite to when the belt is retracted.

A belt recovery method according to one aspect of the present invention for recovering a belt drawn out from a supply source, the belt recovery method is characterized by including a step of exciting a motor and recovering the belt by a roller connected to the motor ; and before cutting off the excitation of the electric motor, the electric motor rotates by a predetermined amount in the opposite direction to the time of the belt retraction.

According to these structures, before the excitation of the electric motor is cut off, the electric motor is stopped in a state where the belt is slack by rotating the electric motor by a predetermined amount in the opposite direction to the time of retracting the belt. Since the tension of the belt is released, even if the excitation of the motor is cut off, it will not be reversed. This eliminates the need to excite the motor when the motor is stopped, so that power consumption and heat generation can be kept low, and the reverse rotation of the motor can be suppressed to prevent imbalance.

In the belt recovery mechanism according to one aspect of the present invention, the motor is excited before the belt is recovered, and the motor is maintained in a stopped state after the motor rotates in the forward direction by a predetermined amount. According to this configuration, the electric motor rotates in the forward direction by a predetermined amount, whereby the belt is re-tensioned and the retracting operation of the belt can be handled.

A tape feeder according to an aspect of the present invention is characterized by having the above-described tape recovery mechanism for causing the tape recovery mechanism to remove, as a tape, an outer cover tape peeled off from a carrier tape in which many components are packaged. It is collected, and the parts exposed from the carrier tape are sent out toward the supply position. According to this configuration, the power consumption and heat generation of the electric motor can be kept low, and misalignment can be prevented, whereby the components can be stably supplied by the tape feeder.

In the tape feeder according to one aspect of the present invention, the motor is excited by a predetermined time from the start of supply of the components predetermined by the operation plan, and the motor is rotated by a predetermined amount in the forward direction. After that, the stop state is maintained. According to this structure, since the belt is re-tensioned based on the operation plan, the supply operation of the components is not delayed due to the operation time of the belt re-tensioning. Thereby, the re-tensioning of the belt does not affect the supply operation of the components, and the reduction of the tact time at the time of supplying the components is suppressed. In addition, the increase in the excitation time of the motor can be suppressed to be short, whereby power consumption and heat generation can be kept low.

In the tape feeder according to one aspect of the present invention, the electric motor is excited during the waiting time when the components are supplied, and the stopped state is maintained after the electric motor rotates in the forward direction by a predetermined amount. According to this structure, since the belt is re-tensioned by using the waiting time when supplying the components, the supply operation of the components is not delayed due to the operation time of the re-tensioning of the belt. Thereby, the re-tensioning of the belt does not affect the supply operation of the components, and the reduction of the tact time at the time of supplying the components is suppressed. In addition, the increase in the excitation time of the motor can be suppressed to be short, whereby power consumption and heat generation 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 that mounts a component sent out from the tape feeder to a substrate. According to this configuration, the power consumption and heat generation of the tape feeder can be kept low, and the mounting head can stably receive components from the tape feeder and mount them on the board.

effect of invention

According to the present invention, before the excitation of the motor is turned off, the motor rotates by a predetermined amount in the opposite direction to the belt retraction, thereby reducing power consumption and heat generation, and preventing the motor from becoming out of step.

Hereinafter, the mounting device of the present embodiment will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the whole of the mounting apparatus according to 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 it can change suitably.

As shown in FIG. 1 , the mounting apparatus 1 is configured to mount various components supplied from the tape feeder 20 on predetermined positions of the substrate W through the mounting head 12 . On the base 10 of the mounting apparatus 1, the board|substrate conveyance part 11 which conveys the board|substrate W in the X-axis direction is arrange|positioned. The board conveyance unit 11 carries and positions the board W before component mounting from the one end side in the X-axis direction to the lower side of the mounting head 12 , and unloads the board W after component mounting from the other end side in the X-axis direction to the outside of the apparatus. In addition, the feeder housings 19 in which the plurality of tape feeders 20 are arranged laterally in the X-axis direction are detachably connected to both sides of the substrate conveyance unit 11 .

A tape reel (supply source) 21 is detachably mounted on the tape feeder 20 , and a plurality of carrier tapes 22 (refer to FIG. 2 ) in which components are packaged are 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 31 (refer to FIG. 2). At the supply position corresponding to the mounting head 12 , the outer cover tape 23 (see FIG. 2 ) on the surface is peeled off from the carrier tape 22 , and the components in the pockets of the carrier tape 22 are exposed to the outside. In addition, the components are not particularly limited to electronic components and the like as long as they can be mounted on the substrate W.

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

As shown in FIG. 2 , the tape feeder 20 is configured to peel off the outer cover tape 23 from the carrier tape 22, and to feed the components exposed from the carrier tape 22 toward a supply position corresponding to the mounting head 12 (see FIG. 1). An opening 24 is provided in the lower portion on the rear side of the feeder frame 25 , and the carrier tape 22 drawn from the reel 21 (see FIG. 1 ) is inserted into the opening 24 , and the carrier tape 22 is inserted along the conveyance guide portion 26 in the feeder frame 25 . The tape 22 is sent out. After the carrier tape 22 is guided obliquely upward from the opening 24 of the feeder frame 25 by the conveyance guide portion 26 , it is guided forward along the upper surface of the feeder frame 25 .

On the front side of the feeder frame 25, an upper cover 27 that covers the carrier tape 22 from above is attached. A slit 28 is formed in the upper cover 27 , the outer cover tape 23 peeled from the carrier tape 22 is folded back through the slit 28 , and the carrier tape 22 after the outer cover tape 23 has been peeled off is conveyed forward in the upper cover 27 . 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 . The components exposed from the supply port 29 are delivered to the suction nozzles 17 of the mounting head 12 .

In addition, on the front side of the feeder frame 25, a sprocket 31 that feeds the carrier tape 22 forward is supported. A supply motor 33 is connected to the sprocket 31 via a reduction gear train 32 . The sprocket 31 is interlocked with the rotation of the supply motor 33 , whereby the carrier tape 22 is conveyed forward by the sprocket 31 , and the components are sequentially supplied toward the supply port 29 . The outer cover tape 23 peeled off from the carrier tape 22 is folded back, and then sent to the collection box 47 on the rear side of the feeder frame 25 through the guide roller 41 , the tension roller 42 , and the pair of collection rollers (rollers) 44 . Inside.

In the vicinity of the entrance of the recovery box 47, a pair of recovery rollers 44 that convey the outer tape 23 in the recovery direction are supported. A traction motor (electric motor) 46 is connected to the recovery roller 44 via a reduction gear train 45 . The collection roller 44 is interlocked with the rotation of the traction motor 46 , whereby the outer tape 23 is conveyed rearward by the collection roller 44 and collected into the collection box 47 . The tension roller 42 supported by the front end of the tension arm 43 is positioned in front of the pair of recovery rollers 44 . By pressing the outer tape 23 by the tension roller 42, the outer tape 23 is recovered in a state where a tension force acts.

As described above, the outer cover tape 23 is satisfactorily peeled off from the carrier tape 22 when the carrier tape 22 is fed out by collecting the outer cover tape 23 while applying a certain tension force by the tension roller 42 . A control circuit 49 is provided in the tape feeder 20 , and the supply motor 33 and the traction motor 46 are connected to the control circuit 49 . The control circuit 49 is communicably connected to the mounting device 1 (see FIG. 1 ) via a communication connector, and controls the excitation timing of the supply motor 33 and the traction motor 46 by receiving a control command from the mounting device 1 .

In addition, the control circuit 49 is constituted by a processor, a memory, and the like that control various motors. The memory is composed of one or more storage media such as ROM (Read Only Memory) and RAM (Random Access Memory) depending on the application, and stores control programs for controlling various motors. In addition, the supply motor 33 and the traction motor 46 may be provided with encoders that detect the rotation amount of each motor. The detection result of the encoder is fed back to each motor, whereby the amount of tape feed by each motor can be controlled with high accuracy.

In addition, in the tape feeder 20, the gear ratio of the traction motor 46 is set to be small so that the operator can manually pull in the outer tape 23 in order to enable installation in a state where the power supply is cut off. In the state where the power supply is cut off, the tensioning force continues to be applied to the outer tape 23 by the tension roller 42. Therefore, the traction motor 46 is generally suppressed by applying a weak excitation to the traction motor 46 due to the tensile force of the outer tape 23. reversal. However, there is a problem in that the traction motor 46 must always be weakly excited, and the power consumption and heat generation of the traction motor 46 increase.

Therefore, in the tape recovery mechanism 40 of the present embodiment, before the excitation of the traction motor 46 is cut off, the traction motor 46 is rotated by a predetermined amount in the opposite direction to the recovery of the outer tape 23 to loosen the outer tape 23 . Thereby, the power consumption and the heat generation amount of the traction motor 46 can be kept low, and the imbalance caused by the reverse rotation of the traction motor 46 can be prevented. In addition, in order to restart the feeding of the carrier tape 22, it is necessary to re-tension the outer tape 23. However, by completing the re-tensioning of the outer tape 23 a little before instructing the feeding operation of the components, the The re-tensioning of the outer tape 23 delays the feeding operation of the tape feeder 20 .

3 and 4 , the supply operation of the components realized by the tape feeder of the present embodiment will be described. FIG. 3 is a diagram showing an example of a supply operation of components according to the present embodiment. FIG. 4 is a diagram showing an example of motor control according to the present embodiment. In addition, each time of the motor control of FIG. 4 is not specifically limited, According to a control program, it changes suitably. In addition, in FIG. 4, it demonstrates using the code|symbol of FIG. 3 suitably.

As shown in FIG. 3(A) , during the supply operation of the components, a control command for the supply operation is output to the supply motor 33 and the traction motor 46 by the control circuit 49 . The supply motor 33 intermittently conveys the carrier tape 22 via the sprocket 31 in accordance with a control command, and sequentially sends the components to the supply port 29 via the carrier tape 22 . The traction motor 46 is synchronized with the supply motor 33 according to the control command, and the outer cover tape 23 peeled off from the carrier tape 22 is fed to the recovery box 47 by the pair of recovery rollers 44 by the same feed amount as the carrier tape 22 .

At this time, since the outer cover tape 23 is tensioned by the tension roller 42 , the pulling force of the recovery roller 44 strongly acts on the outer cover tape 23 at the peeling position where the outer cover tape 23 is peeled from the carrier tape 22 . The carrier tape 22 is strongly fed out to the front side of the tape feeder 20, and the outer tape 23 is strongly pulled in while being folded back toward the rear side of the tape feeder 20, so the outer tape 23 is easily removed from the carrier Strip 22 peels off. Therefore, the case where the outer cover tape 23 is not peeled off from the carrier tape 22 and the outer cover tape 23 is wound on the supply port 29 side of the tape feeder 20 does not occur.

As shown in FIG. 3(B) , when the carrier tape 22 is stopped, a control command to cut off the excitation is output to the supply motor 33 and the traction motor 46 via the control circuit 49 . The supply motor 33 starts to cut off the excitation in accordance with the control command, and the rotation of the sprocket 31 stops, thereby stopping the conveyance of the carrier tape 22 . The traction motor 46 rotates by a predetermined amount in a direction opposite to that when the outer tape 23 is recovered before the excitation is turned off according to the control command. The retraction roller 44 is rotated in the reverse direction by the traction motor 46, and the outer tape 23 is sent out from the recovery box 47, whereby the tension applied to the outer tape 23 is released.

Then, the traction motor 46 starts to cut off the excitation, the reverse rotation of the recovery roller 44 is stopped, and the conveyance of the outer tape 23 is stopped. Since the outer tape 23 is slack, the pulling motor 46 is not strongly exerted by the tensile force from the outer tape 23 . Accordingly, even if the traction motor 46 is not excited, the stopped state can be maintained by the mechanical load torque of the traction motor 46, and the power consumption and heat generation of the traction motor 46 do not increase. In addition, since the reverse rotation of the traction motor 46 is prevented, synchronization with the control command is not lost, and the traction motor 46 does not run out of control due to an imbalance.

As described above, before cutting off the excitation, the traction motor 46 reverses itself to release the tension of the outer tape 23 , thereby stopping in a state that can be controlled in the next recovery operation of the outer tape 23 . In addition, the predetermined amount when the pulling motor 46 rotates in the opposite direction when the outer belt 23 is retracted may be at least such that the pulling force of the outer belt 23 is smaller than the load torque of the pulling motor 46 . Therefore, it is not necessary to completely loosen the outer band 23 by the reverse rotation of the traction motor 46 , and the outer band 23 may exert a slight tensile force on the traction motor 46 .

As shown in FIG. 3(C) , when the supply of components is resumed, before the control circuit 49 outputs the control command for the supply operation, the control circuit 49 outputs the control command for the start of supply preparation to the traction motor 46 . The traction motor 46 is excited by the control command before the outer tape 23 is recovered, and is rotated by a predetermined amount in the same forward direction as the recovery direction of the outer tape 23 . The collection roller 44 is rotated forward by the pulling motor 46, and the outer tape 23 is fed into the collection box 47, thereby removing slack from the outer tape 23 and re-tensioning the outer tape 23.

The stopped state is maintained after the traction motor 46 is rotated by a predetermined amount by the excitation of the traction motor 46 . At this time, although the outer belt 23 is re-tensioned, the traction motor 46 is not reversed by the pulling force of the outer belt 23 because the braking force is applied to the traction motor 46 by the excitation. Then, the control command of the supply operation is output again to the supply motor 33 and the traction motor 46 by the control circuit 49, and the feeding operation of the carrier tape 22 and the recovery operation of the outer cover tape 23 are performed. As described above, when the traction motor 46 is rotated in the forward direction by a predetermined amount, the outer cover tape 23 is re-tensioned to cope with the tape retracting operation.

In this case, the re-tensioning of the outer tape 23 is completed a little before the feeding operation of the carrier tape 22 is started. For example, since the mounting device 1 (refer to FIG. 1 ) operates based on the operation plan, the traction motor 46 is excited before a predetermined time before the feeding operation of the carrier tape 22 predetermined in the operation plan, and the traction motor 46 is rotated in the forward direction by a predetermined amount and then maintained in a stopped state. In addition, the traction motor 46 may be excited during the waiting time when the tape feeder 20 supplies components to the mounting head 12 (see FIG. 1 ), and the traction motor 46 may be rotated in the forward direction by a predetermined amount and then maintained in a stopped state.

As shown in FIG. 4 , based on the operation plan, the start of supply preparation is notified from the mounting device 1 (see FIG. 1 ) to the traction motor 46 of the tape feeder 20 50 [ms] or more before the start of the component supply operation. control command. The traction motor 46 sends back a state response to the mounting device 1, and the traction motor 46 is excited to start supply preparation. At this time, after 2 [ms] of current up (Current up), it takes 50 [ms] to 210 [ms] to re-tension the outer sealing tape 23 . As described above, the preparation for the retracting operation of the outer tape 23 by the traction motor 46 is completed before the supply operation of the components.

After the elapse of 50 [ms] or more from the start of re-tensioning, the mounting device 1 notifies the supply motor 33 and the traction motor 46 of the control command for the supply operation. The supply motor 33 sends out the carrier tape 22 after the current rises for 2 [ms] and returns a state response to the mounting device 1 . The traction motor 46 waits for the current supplied to the motor 33 to rise, and then recovers the outer tape 23 and returns a state response to the mounting device 1 . The feeding operation of the supply motor 33 and the retracting operation of the traction motor 46 are synchronized, and the interval from the receipt of the command to the reply of the response is set to, for example, 60 [ms].

Since the re-tensioning of the outer tape 23 is performed 50 [ms] or more before the feeding operation of the carrier tape 22, the preparation for the retracting operation of the traction motor 46 is completed when the feeding operation is performed by the supply motor 33. In addition, only the excitation time of the traction motor 46 is slightly longer, so that the increase in the excitation time of the traction motor 46 can be suppressed short and the power consumption and heat generation of the traction motor 46 can be kept low. In addition, the outer tape 23 is re-tensioned by utilizing the standby time when the component supply operation is not performed based on the operation plan, so that the component supply operation is not delayed due to the operation time of the re-tensioning of the outer tape 23 .

Then, 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 to complete the supply preparation is notified from the mounting apparatus 1 to the supply motor 33 and the traction motor 46 . The supply motor 33 sends back a state response to the mounting device 1, and turns off the excitation after 100 [ms] has elapsed. The traction motor 46 responds to the mounting device 1 via the state, and after 45 [ms] or more slackens the outer tape 23, the excitation is turned off after 100 [ms] elapses. Since the outer band 23 is slack, even if the excitation of the traction motor 46 is cut off, it will not be reversed.

Furthermore, when the mounting head 12 returns to the tape feeder 20 in order to acquire the components after mounting the components on the board, the outer tape is made to take advantage of the waiting time when the components are supplied from the tape feeder 20 to the mounting head 12 . 23 Re-tension. Also in this case, similarly to the above, before the start of the feeding operation of the carrier tape 22 by 50 [ms] or more, the outer tape 23 is re-tensioned by the traction motor 46 to prepare the outer tape 23 Preparations for the recovery action. By utilizing the idle time before the component supply operation, the re-tensioning of the outer tape 23 does not affect the component supply operation, thereby suppressing a reduction in tact time during component supply.

As described above, in the tape recovery mechanism 40 of the present embodiment, before the excitation of the traction motor 46 is cut off, the traction motor 46 is rotated by a predetermined amount in the opposite direction to the recovery of the outer tape 23, thereby causing the outer tape 23 to be recovered. The traction motor 46 is stopped in a state where the tape 23 has slack. Since the tension of the outer belt 23 is released, even if the excitation of the traction motor 46 is cut off, the reverse rotation will not occur. Thereby, since excitation is not performed when the traction motor 46 is stopped, power consumption and heat generation can be kept low, and the reverse rotation of the traction motor 46 can be suppressed to prevent imbalance.

In addition, in this Embodiment, although the structure which applied a tape collection|recovery mechanism to a tape feeder was demonstrated, it is not limited to this structure. As long as the tape recovery mechanism is a mechanism for recovering the tape drawn out from the supply source, it can be applied to various processing apparatuses that carry out tape conveyance.

In addition, in the present embodiment, the tape recovery mechanism is applied to the structure in which the traction motor of the tape feeder is controlled to recover the outer wrapping tape. The structure of the carrier tape for recycling.

In addition, in the present embodiment, the recovery rollers only need to be configured to convey the tape in the recovery direction. For example, the outer peripheral surface may be a friction surface, or feed teeth may be formed on the outer peripheral surface.

In addition, in this embodiment, although the suction nozzle was illustrated as a suction nozzle, it is not limited to this structure. The suction nozzle should just be able to hold a member, for example, a holding suction nozzle may be sufficient.

In addition, in the present embodiment, the substrate is not limited to a printed circuit board as long as it can mount various components, and may be a flexible substrate mounted on a tool substrate.

In addition, the program of this embodiment may be stored in a storage medium. The recording medium is not particularly limited, and may be a non-volatile recording medium such as an optical disk, a magneto-optical disk, and a flash memory.

In addition, the embodiment and the modification of the present invention have been described, but as another embodiment of the present invention, the above-described embodiment and modification may be combined in whole or in part.

In addition, the embodiment of the present invention is not limited to the above-described embodiment and modification examples, and various changes, replacements, and modifications can be made without departing from the spirit of the technical idea of the present invention. And if the technical idea of the present invention can be realized in other ways through the advancement of technology or other derived technologies, this method can be used for implementation. Therefore, 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 recovery mechanism for recovering the tape drawn out from the supply source is characterized by having a recovery roller for conveying the tape in the recovery direction and a motor connected to the recovery roller, and before the excitation of the motor is cut off , the motor rotates by a predetermined amount in the opposite direction to when the belt is retracted. According to this configuration, the motor is rotated by a predetermined amount in the opposite direction to the time of retracting the belt before the excitation of the motor is cut off, thereby stopping the motor in a state where the belt is slack. Since the tension of the belt is released, even if the excitation of the motor is cut off, it will not be reversed. Thereby, since excitation is not performed when the motor is stopped, power consumption and heat generation can be kept low, and the reverse rotation of the motor can be suppressed to prevent imbalance.
