Description

This disclosure relates to a component mounting machine, a component processing device, and a component processing method.

JP 2021-158263 A

However, components supplied by the component supply feeder are not always handed over to the mounting unit as is. Depending on the specifications of the component mounting machine, there are cases where it is required to process the leads, etc. before handing them over to the mounting unit. In such cases, it can be difficult to balance processing the components and maintaining production efficiency, and it is desirable to achieve high production efficiency even in specifications that require component processing.

Therefore, the object of the present disclosure is to provide a component mounter, a component processing device, and a component processing method that can solve the above problems and improve production efficiency.

To achieve the above object, the component mounting machine of the present disclosure includes a plurality of pallets each capable of holding a component, a pallet drive unit that rotates the plurality of pallets lined up in an endless manner to move each pallet in the following order: a component receiving position where components are received from a component supply feeder, a component processing position where the received components are processed, and a component transfer position where the processed components are transferred to a mounting unit, and a component processing device that has access to the component processing positions and bends the leads of the components at the component processing positions to lay the components sideways.

The component processing device disclosed herein is capable of accessing a component processing position located between a component receiving position where each pallet receives components from a component supply feeder and a component delivery position where each pallet delivers components to a mounting unit in a component mounting machine in which multiple pallets, each capable of holding components, rotate endlessly, and bends the leads of the components at the component processing position to lay the components sideways.

The component processing method disclosed herein also involves a component mounting machine in which multiple pallets capable of holding components rotate endlessly, and uses a component processing device that can access a component processing position located between a component receiving position where each pallet receives components from a component supply feeder and a component delivery position where each pallet delivers components to a mounting unit, to bend the leads of the component at the component processing position and lay the component sideways.

This disclosure can improve production efficiency.

Below, exemplary embodiments of a component mounter, component processing device, and component processing method according to the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the specific configurations of the following embodiments, and configurations based on similar technical ideas are included in the present disclosure.

(Embodiment)
First, a component mounter according to an embodiment of the present disclosure will be described with reference to FIG.

Figure 1 is a schematic plan view of a component mounter 1 according to an embodiment.

The component mounter 1 shown in FIG. 1 is a device that mounts a component 2 with leads on a substrate 3. In this embodiment, the component 2 is a radial taping component. The substrate 3 on which the component 2 is mounted becomes a "component mounting substrate." In FIG. 1, the component 2 is shown only in an exemplary location.

The component mounter 1 includes a board holding table 4, a mounting unit 6, a pallet system 8, a pallet drive unit 10, a component supply feeder 12, and a control unit 14.

The substrate holding table 4 is a table that positions and holds the substrate 3 on its upper surface. In this embodiment, the substrate holding table 4 is movable in the horizontal direction.

The mounting unit 6 is a unit that mounts components 2 onto a board 3 that is positioned by a board holding table 4. In this embodiment, the mounting unit 6 includes a transfer head 21 and an insertion head 23.

The transfer head 21 and the insertion head 23 are each members capable of holding a component 2. The transfer head 21 transfers the component 2 supplied by the pallet system 8 to the insertion head 23. The insertion head 23 inserts the component 2 transferred from the transfer head 21 into the board 3 for mounting. Here, the position where the pallet system 8 passes the component 2 to the transfer head 21 is referred to as the component transfer position P3.

The pallet system 8 is a system that holds and transports multiple parts 2. The pallet system 8 has multiple pallets 9, and each pallet 9 can hold one or multiple parts 2. The multiple pallets 9 are connected endlessly and driven by the pallet drive unit 10, for example, in the transport direction X1.

In this embodiment, the pallet drive unit 10 is a plurality of pulleys provided inside the plurality of pallets 9. The pallet drive unit 10 is driven by a servo motor (not shown) and can rotate in both the forward and reverse directions.

The component supply feeder 12 is a device for supplying components 2 to the pallet 9 of the pallet system 8. The component supply feeder 12 in this embodiment is a tape feeder that supplies radially taped components as the components 2, and includes, for example, multiple feeders 12A, 12B. The number of feeders 12A, 12B is not limited to two, and may be any number. It may further include a feeder that supplies components of a type different from radially taped components (e.g. axial components) in addition to radially taped components. Here, the position at which the pallet system 8 receives the components 2 from the component supply feeder 12 is defined as the component receiving position P1.

The control unit 14 is a component that controls the various components of the component mounter 1. The control unit 14 is, for example, configured as a microcomputer having a circuit board. The control unit 14 is electrically connected to each of the components that make up the component mounter 1.

The component mounter 1 of this embodiment further includes a component positioning device 30, a first component processing device 32, and a second component processing device 34. As shown in FIG. 1, the component positioning device 30, the first component processing device 32, and the second component processing device 34 are arranged in this order along the conveying direction X1.

The part positioning device 30 is a device for positioning the part 2 held on the pallet 9. By positioning the part 2, it is possible to improve the accuracy with which the subsequent first part processing device 32 and second part processing device 34 process the part 2.

The first component processing device 32 and the second component processing device 34 are devices for processing the component 2 positioned by the component positioning device 30. The first component processing device 32 in this embodiment is a device that bends the leads of the component 2 to lay the component 2 sideways. The second component processing device 34 in this embodiment is a device that cuts the leads of the component 2 laid sideways by the first component processing device 32. By arranging the first component processing device 32 and the second component processing device 34 in order along the transport direction X1, the component 2 with the component body laid sideways and the leads cut to a predetermined length can be supplied to the mounting unit 6.

Here, the position where the first part processing device 32 processes the part 2 is referred to as the part processing position P2.

When the pallet system 8 rotates the multiple pallets 9 endlessly, each pallet 9 moves in the following order: part receiving position P1, part processing position P2, and part transfer position P3.

The component mounter 1 of this embodiment is provided with component processing devices 32, 34 at the component processing position P2, which is located between the component receiving position P1 and the component delivery position P3. This leads to improved production efficiency, for example, in comparison with a configuration in which processed components 2 are supplied from the component supply feeder 12, as it becomes easier to retrieve components 2 that have been supplied to the pallet system 8 in an unprocessed state when the operation of the component mounter 1 is interrupted.

The component mounter 1 of this embodiment further improves the configuration of the first component processing device 32. The component positioning device 30 and the second component processing device 34 may use any configuration as long as they can perform their respective functions, and detailed explanations will be omitted. The configuration and operation of the first component processing device 32 will be explained below using Figures 2 to 10E and Figures 11A and 11B.

Figures 2 and 3 are perspective views of the first part processing device 32 and a portion of the pallet system 8, respectively, viewed from different directions, and Figures 4 and 5 are plan views of the first part processing device 32 and a portion of the pallet system 8, respectively, viewed from above.

As shown in Figures 2 to 5, the first part processing device 32 includes a first guide 36, a second guide 38, a support block 40, a pusher 42, and a cylinder 44. The entire first part processing device 32 including these components is configured to be movable back and forth in a direction toward the pallet system 8 (first direction A1) and a direction away from the pallet system 8 (second direction A2). The support block 40 is not shown in Figures 4 and 5.

Figures 2, 3, and 5 show the first part processing device 32 moving forward in the first direction A1 to access the part 2A at the part processing position P2 (access position). Figure 4 shows the first part processing device 32 moving backward in the second direction A2 to retreat from the part 2A at the part processing position P2 (retract position).

As shown in Figures 2 to 5, each of the multiple components 2 is held by a pallet 9 of the pallet system 8, and in particular, two leads are clamped and held in an upright position.

The first guide 36 and the second guide 38 are each a pair of members for processing the part 2A at the part processing position P2. Both the first guide 36 and the second guide 38 can engage with the part 2A at the part processing position P2 when the first part processing device 32 advances in the first direction A1.

The first guide 36 has a first end 46 that can engage with the component 2A. The second guide 38 has a second end 48 that can engage with the component 2A. By pushing the first end 46 in contact with the upper portion of the lead of the component 2A and supporting the lower portion of the lead of the component 2A from the opposite side with the second end 48, the lead of the component 2A bends with the contact point with the second end 48 as a fulcrum, and the component body can be tilted sideways. Figures 2, 3, and 5 show an example of the state in which the component 2A is tilted sideways.

The first guide 36 and the second guide 38 are each supported by a support block 40 in a state in which they can rotate around a rotation axis Z1 that extends in the vertical direction. While the first guide 36 is rotatable, the position of the second guide 38 is fixed by a cylinder 44. By making the first guide 36 function as a movable guide and the second guide 38 function as a fixed guide, the operation of pinching and bending the leads of the component 2A from both sides can be performed with high precision.

If the second guide 38 is released from the cylinder 44, both guides 36 and 38 can function as movable guides and can be operated in different ways. Details will be described later.

The pusher 42 is a member for selectively engaging with the first guide 36 to operate the first guide 36. The pusher 42 is connected to a drive source (cylinder 80 in FIG. 8) not shown, and can reciprocate in a direction toward the first guide 36 (first direction B1) and a direction away from the first guide 36 (second direction B2). 2, 3, and 5 show a state in which the pusher 42 advances in the first direction B1 to operate the first guide 36 (the pusher 42 is in an operating position), and FIG. 4 shows a state in which the pusher 42 retreats in the second direction B2 to not operate the first guide 36 (the pusher 42 is in a retracted position).

The first guide 36 has a third end 50 different from the first end 46. The first guide 36 rotates around a rotation axis Z1 located between the first end 46 and the third end 50. The third end 50 is provided at a position opposite the pusher 42 and is pressed when the pusher 42 advances. When the pusher 42 presses the third end 50, the first guide 36 rotates in a first rotation direction R1 around the rotation axis Z1 as shown in FIG. 5. The first rotation direction R1 is a direction in which the third end 50 opens outward and the first end 46 closes inward. When the first end 46 closes inward, it comes into contact with the lead of the component 2A at the component processing position P2 and bends the lead.

The second guide 38 has a fourth end 52 that is different from the second end 48. The fourth end 52 is provided at a position facing the pusher 42, similar to the third end 50. As shown in FIG. 4, unlike the third end 50, the fourth end 52 is disposed at a position spaced apart from the third end 50 so that the second guide 38 does not rotate significantly even when the pusher 42 moves forward.

The cylinder 44 is a drive unit for controlling the rotational position of the second guide 38. The cylinder 44 has a cylinder body 54 and a rod 56. The cylinder body 54 is attached to the second guide 38 via a mounting bracket 58 and rotates integrally with the second guide 38. The rod 56 is a rod-shaped member that protrudes from the cylinder body 54 and can advance and retreat in the forward and backward directions relative to the cylinder body 54.

In the state shown in Figures 2 to 5, the rod 56 advances in the first direction C1 and abuts against a fixed stopper 60 fixedly provided on the first part processing device 32. When the rod 56 abuts against and presses against the fixed stopper 60, the cylinder 44 having the rod 56 and the second guide 38 to which the cylinder 44 is attached rotate integrally in a second rotation direction R2 around the rotation axis Z1. The second rotation direction R2 is the opposite direction to the first rotation direction R1, and is the direction in which the fourth end 52 opens outward and the second end 48 closes inward. By projecting the rod 56 in this way, the second guide 38 can be fixed in a predetermined rotational position and function as a fixed guide.

Although not shown in Figures 2 and 3, as shown in Figures 4 and 5, a biasing member 62 is further provided for biasing the first guide 36 and the second guide 38 in a predetermined rotational direction.

The biasing member 62 is a member for biasing the first guide 36 in the second rotation direction R2 and biasing the second guide 38 in the first rotation direction R1. One end of the biasing member 62 is attached to the third end 50 of the first guide 36, and the other end is attached to the fourth end 52 of the second guide. In this embodiment, the biasing member 62 is a tension spring that draws the third end 50 and the fourth end 52 toward each other.

By providing the biasing member 62, the first guide 36 and the second guide 38 are biased in a direction in which the third end 50 and the fourth end 52 approach each other. The first guide 36 rotates in the second rotation direction R2 and stops, for example, by contact with the tip of the pusher 42. Although the second guide 38 is biased in the first rotation direction R1, it is forcibly rotated in the second rotation direction R2 by the drive of the cylinder 44 described above, so that the fourth end 52 is positioned away from the third end 50 against the biasing force of the biasing member 62.

The rotational position of the second guide 38 can be changed by controlling the drive of the cylinder 44 described above. In Figs. 2 to 5, the rod 56 is shown to be in contact with the fixed stopper 60 (the cylinder 44 is in the operating position) when the rod 56 is retracted, and the rod 56 is released from contact with the fixed stopper 60 (the cylinder 44 is in the retracted position), and the second guide 38 is forced to rotate in the first rotation direction R1. The second guide 38 stops when the fourth end 52 comes into contact with the tip of the pusher 42, similar to the first guide 36, for example. When the pusher 42 is advanced in this state, both the third end 50 and the fourth end 52 are pressed, and the first guide 36 and the second guide 38 rotate in synchronization so that the first end 46 and the second end 48 approach each other.

In this way, when the rod 56 is retracted, both the first guide 36 and the second guide 38 can function as movable guides.

As described above, by controlling the drive of the cylinder 44, it is possible to switch between a first mode in which the first guide 36 functions as a "movable guide" and the second guide 38 functions as a "fixed guide" as shown in Figures 2 to 5 and 10A to 10E, and a second mode in which the two guides 36, 38 function as movable guides as shown in Figures 11A and 11B. This makes it possible to accommodate processing methods other than bending the leads of component 2A and laying component 2A sideways (for example, correcting the orientation of component 2A, correcting the pitch of the leads, correcting the inclination of the leads, forming kinks in the leads, etc.), and to achieve "multi-processing."

Furthermore, in this embodiment, the first end 46 and the second end 48 are detachably attached to the first guide 36 and the second guide 38, respectively, and can be changed to different shapes. Therefore, by adjusting (1) the usage mode (first mode or second mode) of the guides 36, 38 and (2) the shapes of the first end 46 and the second end 48, it is possible to accommodate various processing methods.

Figures 6 and 7 are enlarged perspective views showing the peripheral configuration of part 2A at part processing position P2. Part 2 is shown in Figure 6, and part 2 is not shown in Figure 7.

As shown in FIG. 6, the first end 46 and the second end 48 are positioned so as to overlap the lead of the component 2 in the height direction along the Z axis, and the first end 46 is positioned higher than the second end 48. When the first end 46 rotates in the first rotation direction R1, it comes into contact with the lead of the component 2 at a position higher than the second end 48, and bends the lead supported by the second end 48 in the first rotation direction R1. The component 2A is bent, for example, by approximately 90 degrees, and the component body changes from an upright position to a horizontal position.

A first auxiliary end 66 and a second auxiliary end 68 are provided below the first end 46 and the second end 48, respectively. The auxiliary ends 66, 68 are portions for temporarily positioning the leads of the component 2A by clamping them below the first end 46 and the second end 48, respectively.

The first auxiliary end 66 is an end of the first guide 36 and rotates integrally with the first end 46. The second auxiliary end 68 is an end of the second guide 38 and is fixed in the same manner as the second end 48 (when the rod 56 is protruding).

The first auxiliary end 66 and the second auxiliary end 68 are positioned so that they overlap in the height direction along the Z axis. When the first auxiliary end 66 rotates together with the first end 46 in the first rotation direction R1, the lead of the component 2A can be sandwiched and positioned between the first auxiliary end 66 and the second auxiliary end 68. Positioning the lead can improve the processing accuracy when the first end 46 and the second end 48 bend the portion above the positioning location.

6 and 7, each pallet 9 has a pair of holding claws 70, 72. The holding claws 70, 72 are members for holding the component 2 in an upright position by pinching the lead of the component 2. In this embodiment, one of the holding claws 70 is fixed, while the other holding claw 72 is rotatable about the rotation axis Z2. The other holding claw 72 is biased in a closing direction by a biasing member (not shown). When transferring the component 2 from the component supply feeder 12 to the pallet 9, the component supply feeder 12 engages with the holding claws 72 so that the holding claws 72 open. With the holding claws 72 open, the lead of the component 2 is supplied into the gap between the holding claws 70, 72, and then the component supply feeder 12 retracts, causing the holding claws 72 to close. This allows the lead of the component 2 to be pinched and held between the holding claws 70, 72.

Figure 8 is a block diagram showing the control system of component mounter 1.

As shown in FIG. 8, the control unit 14 is electrically connected to each component of the component mounter 1, specifically, the pallet drive unit 10, the mounting unit 6, the component positioning device 30, the second component processing device 34, and the first component processing device 32.

The first part processing device 32 includes a first guide drive unit 74, a second guide drive unit 76, and a device drive unit 78.

The first guide driving unit 74 is a driving unit for driving the first guide 36 described above, and includes a pusher 42 and a cylinder 80. The cylinder 80 is a driving unit for moving the pusher 42 back and forth in the first direction B1 and the second direction B2, and is not shown in Figures 1 to 7.

The second guide drive unit 76 is a drive unit for driving the second guide 38 described above, and is equipped with a cylinder 44 having a rod 56.

The device drive unit 78 is a drive unit for moving the entire first part processing device 32 back and forth in the first direction A1 and the second direction A2, and is equipped with a motor 82. The motor 82 is connected to the support block 40, etc., by a cam mechanism (not shown), for example, and moves the components such as the support block 40 and the guides 36 and 38 in the back and forth direction as a whole.

An example of the operation of machining part 2A at part machining position P2 using first part machining device 32 having the above-mentioned configuration will be described with reference to Figure 9 and Figures 10A to 10E.

Figure 9 is a flowchart showing an example of a method for processing component 2A by component mounter 1, and Figures 10A to 10E are schematic plan views for explaining the method for processing component 2A according to the flowchart of Figure 9. Each step of the flow shown in Figure 9 is executed by, for example, control unit 14.

The control unit 14 advances the pallet 9 by one pitch (S1). Specifically, the control unit 14 drives the pallet drive unit 10 to rotate, thereby advancing the multiple pallets 9 by one pitch in the conveying direction X1 and stopping them.

Figure 10A shows the state where the pallet 9 has been advanced one pitch and stopped. As shown in Figure 10A, part 2B, which has been turned sideways by the processing of the first part processing device 32, stops at a position one pitch downstream of part processing position P2, and part 2C, which is the new processing target, stops at part processing position P2. When the pallet 9 moves, the first part processing device 32 retreats in the second direction A2.

The control unit 14 advances the first component processing device 32 (S2). Specifically, the control unit 14 drives the motor 82 (FIG. 8) of the device drive unit 78 to advance the first component processing device 32 in the first direction A1, as shown in FIG. 10B. This allows the first guide 36 and the second guide 38 to access the component 2C at the component processing position P2. By retracting the pusher 42 in the second direction B2, a gap is created between the first end 46 and the second end 48, and the lead of the component 2 can be placed in this gap.

The control unit 14 advances the pusher 42 (S3). Specifically, the control unit 14 drives the cylinder 80 (FIG. 8) of the first guide drive unit 74 to advance the pusher 42 in the first direction B1, as shown in FIG. 10C. The advanced pusher 42 presses the third end 50 of the first guide 36, causing the first guide 36 to rotate in the first rotation direction R1. The rotation of the first guide 36 moves the first end 46 of the first guide 36 in a direction approaching the second end 48 of the second guide 38, and pushes the upper portion of the lead of the component 2 supported by the second end 48 to the opposite side, thereby bending the lead of the component 2 and laying the component body on its side, as shown in FIG. 6, etc.

The control unit 14 retracts the pusher 42 (S4). Specifically, the control unit 14 drives the cylinder 80 of the first guide drive unit 74 to retract the pusher 42 in the second direction B2, as shown in FIG. 10D. As the pusher 42 retracts, the first guide 36 rotates in the second rotation direction R2 due to the biasing force of the biasing member 62, and the first end 46 of the first guide 36 moves away from the lead of the component 2. This allows the lead of the component 2 to be released from the gap between the first end 46 and the second end 48.

The control unit 14 causes the first component processing device 32 to move backward (S5). Specifically, the control unit 14 drives the motor 82 of the device drive unit 78, so that the first component processing device 32, including the first guide 36 and the second guide 38, moves backward in the second direction A2 as a whole, as shown in FIG. 10E. As the first component processing device 32 moves away from the component processing position P2, the pallet 9 can move in the conveying direction X1 without interfering with the first component processing device 32. After that, when the pallet system 8 moves the pallet 9 one pitch (S1), the processed component 2C is sent downstream of the component processing position P2, and the component 2D, which is the new processing target, stops at the component processing position P2.

By repeatedly executing steps S1 to S5, the components 2 held on the pallet 9 can be processed sequentially at the component processing position P2. The components 2 processed by the first component processing device 32 are processed by the second component processing device 34 to cut the leads, and are finally supplied to the mounting unit 6.

According to the above-described configuration and method, a first component processing device 32 is provided that can access the component processing position P2 located between the component receiving position P1 and the component delivery position P3, and processes the components 2 while they are being transported by the pallet system 8. This allows the components 2 to be processed at a position closer to the component delivery position P3, compared to a configuration in which, for example, already processed components 2 are supplied to the pallet 9 from the component supply feeder 12. When the operation of the component mounter 1 is stopped midway, it becomes possible to recover unprocessed components 2 between the component supply position P1 and the component processing position P2, which makes it easier to reuse the components 2 and leads to improved production efficiency.

When installing the component positioning device 30 and the component processing devices 32, 34 in the component mounter 1, a method of fixing each device by fitting the bottom portion of each device into a specified slot is considered. In this embodiment, the first component processing device 32 has two guides 36, 38 as an integral configuration, so there is no need to configure each guide separately and attach them to different slots, and it is sufficient to attach the first component processing device 32 including the two guides 36, 38 to one slot. This makes it possible to reduce the number of slots occupied, and adjacent component positioning devices 30 and second component positioning devices 34 can be positioned closer to each other, thereby realizing space savings.

Next, a usage mode (second mode) in which the rod 56 of the cylinder 44 is retracted, which differs from the usage mode (first mode) shown in Figures 2 to 10E, will be described with reference to Figures 11A and 11B.

Figures 11A and 11B are schematic plan views for explaining a second mode of use of the first part processing device 32. Figure 11A shows the state in which the first part processing device 32 retreats from the part processing position P2 in the second direction A2, and Figure 11B shows the state in which the first part processing device 32 advances in the first direction A1 to access the part 2C at the part processing position P2.

As shown in FIG. 11A, by retracting the rod 56 of the cylinder 44 in the second direction C2, the rod 56 is separated from the fixed stopper 60. In this state, the cylinder 44 does not generate a force that rotates the second guide 38 in the second rotation direction R2, so the second guide 38 rotates in the first rotation direction R1 due to the biasing force of the biasing member 62.

In the example shown in FIG. 11A, the third end 50 of the first guide 36 and the fourth end 52 of the second guide 38 both abut against the tip of the pusher 42 and are stopped.

From the state shown in FIG. 11A, when the first part processing device 32 is advanced in the first direction A1 (S3) and the pusher 42 is advanced in the first direction B1 (S4), the state shown in FIG. 11B is obtained.

As shown in FIG. 11B, the advancement of the pusher 42 presses both the third end 50 and the fourth end 52, causing the first guide 36 to rotate in the first rotation direction R1 and the second guide 38 to rotate in the second rotation direction R2. The first end 46 and the second end 48 move toward each other to sandwich the leads of the component 2. Because the first end 46 and the second end 48 can be changed to have a shape different from that of the first embodiment, it is possible to perform processing methods other than the processing of tilting the component 2 sideways shown in FIGS. 10A to 10E, such as sandwiching the leads of the component 2 to correct the attitude, lead pitch, or tilt of the component 2, or forming a kink in the lead.

The first embodiment shown in Figures 10A to 10E and the second embodiment shown in Figures 11A and 11B do not necessarily use different machining methods for the part 2, and the same machining method may be used. In this case, the shapes of the first end 46 and the second end 48 may be the same without being changed.

(Action and Effects)
As described above, the component mounting machine 1 of this embodiment comprises a plurality of pallets 9 each capable of holding a component 2, a pallet drive unit 10 which rotates the plurality of pallets 9 lined up in an endless manner to move each pallet 9 in the following order: a component receiving position P1 where components 2 are received from a component supply feeder 12, a component processing position P2 where the received components 2A are processed, and a component transfer position P3 where the processed components 2A are passed to the mounting unit 6, and a first component processing device 32 which is accessible to the component processing position P2 and which bends the leads of the components 2A at the component processing position P2 to lay the components 2A on their side.

According to this configuration, in a configuration in which the first component processing device 32 supplies the component 2A in a laid-down state to the mounting unit 6, the component 2A is processed between the component receiving position P1 and the component delivery position P3. This allows the component 2A to be processed at a position closer to the component delivery position P3, compared to a configuration in which, for example, the processed component 2 is supplied from the component supply feeder 12 to the pallet 9. This leads to improved production efficiency, such as making it easier to collect the unprocessed component 2 when the operation of the component mounter 1 is stopped.

In addition, in the component mounter 1 of the embodiment, the first component processing device 32 has a first guide 36 and a second guide 38 that face each other to sandwich the component 2A at the component processing position P2, the first guide 36 has a first end 46 that can contact the component 2A when moved in a direction approaching the component 2A at the component processing position P2, and the second guide 38 has a second end 48 that contacts and supports the lead of the component 2A at the component processing position P2 from the opposite side to the first guide 36. With this configuration, the lead of the component 2A can be bent and the component 2A can be laid on its side with the simple configuration of the first guide 36 and the second guide 38.

In addition, in the component mounter 1 of the embodiment, the first guide 36 has a third end 50 different from the first end 46 and is rotatable around a rotation axis Z1 (first rotation axis) located between the first end 46 and the third end 50, and the first component processing device 32 further includes a pusher 42 (first guide drive unit 74) that moves between an operating position where it engages with the third end 50 of the first guide 36 to rotate the first guide 36 in a direction in which the first end 46 approaches the component 2A, and a retracted position where it retracts away from the third end 50. With this configuration, the first guide 36 can be easily operated by driving the pusher 42.

In addition, in the component mounter 1 of the embodiment, the first component processing device 32 further includes a biasing member 62 that biases the first guide 36 in the second rotation direction R2 in which the first end 46 moves away from the component 2A at the component processing position P2. With this configuration, the first guide 36 can be retracted except when it is being operated.

In addition, in the component mounter 1 of the embodiment, the second guide 38 has a fourth end 52 provided at a position opposite the third end 50 of the first guide 36, and the fourth end 52 is disposed at a distance from the third end 50 of the first guide 36. With this configuration, when the pusher 42 contacts the third end 50 of the first guide 36 to rotate the first guide 36, it is possible to design the second guide 38 to suppress contact with the fourth end 52 of the second guide 38 and not rotate it significantly, and the second guide 38 can function as a fixed guide. The term "fixed guide" does not necessarily mean a guide that does not move at all when the pusher 42 is driven, but may also mean a guide that moves a smaller amount than a movable guide.

In the component mounter 1 of the embodiment, the second guide 38 can rotate around a rotation axis Z2 (second rotation axis) located between the second end 48 and the fourth end 52 between a first rotation position (FIG. 11A) where the fourth end 52 approaches the third end 50 and a second rotation position (FIG. 11B) where the fourth end 52 moves away from the third end 50, and the first component processing device 32 further includes a cylinder 44 (second guide drive unit 76) that fixes the second guide 38 at the second rotation position. With this configuration, when the fixation by the cylinder 44 is released, the second guide 38 can move to the first rotation position, and the pusher 42 can contact both the first guide 36 and the second guide 38. This makes it possible to operate the first guide 36 and the second guide 38 in a manner different from when the second guide 38 is fixed at the second rotation position.

In addition, in the component mounter 1 of the embodiment, the second guide drive unit 76 includes a cylinder 44 having a rod 56 that reciprocates back and forth and is attached to the second guide 38, and when the rod 56 protrudes, the cylinder 44 abuts against a fixed stopper 60 provided on the first component processing device 32, thereby rotating the second guide 38 from the first rotation position to the second rotation position. With this configuration, by controlling the position of the rod 56 of the cylinder 44, the second guide 38 can be selectively fixed at the second rotation position, and the second guide 38 can be selectively positioned at either the first rotation position or the second rotation position.

In addition, in the component mounter 1 of the embodiment, the biasing member 62 is attached between the first guide 36 and the second guide 38, and biases the second guide 38 toward the first rotation position. With this configuration, the biasing member 62 that biases the first guide 36 can be used to bias the second guide 38 to keep it retracted except during operation.

In addition, in the component mounter 1 of the embodiment, the first end 46 and the second end 48 are replaceable with ends of different shapes. With this configuration, by replacing at least one of the first end 46 and the second end 48 with an end of a different shape, it becomes possible to perform processing other than laying the component 2A on its side. It is not limited to the case that both the first end 46 and the second end 48 are replaceable, as long as at least one of the first end 46 and the second end 48 is replaceable with an end of a different shape.

In the component mounter 1 of the embodiment, the first component processing device 32 further includes a support block 40 to which the first guide 36 and the second guide 38 are attached and supported, and a device drive unit 78 that reciprocates the support block 40 to move the first guide 36 and the second guide 38 between an access position where the component 2A at the component processing position P2 can be accessed and a retracted position retracted from the component processing position P2. With this configuration, it is possible to retract the two guides 36 and 38 to the retracted position when the pallet 9 is moving, and move the two guides 36 and 38 to the access position when the pallet 9 is stopped to process the component 2A.

In addition, the component mounter 1 of the embodiment further includes a control unit 14 for controlling the operation of the first component processing device 32. The control unit 14 controls the pallet drive unit 10, the pusher 42 (first guide drive unit 74), and the device drive unit 78 to move the first guide 36 and the second guide 38 from the retreat position to the access position (S2) when the multiple pallets 9 are stopped, rotate the first guide 36 to process the component 2A at the component processing position P2 (S3), retreat the first guide 36 and the second guide 38 from the access position to the retreat position (S4, S5), and then move the multiple pallets 9 (S1). With this configuration, while the two guides 36 and 38 are retreated to the retreat position when the pallet 9 is moving, the guides 36 and 38 can be moved to the access position when the pallet 9 is stopped to process the component 2A.

In addition, the first component processing device 32 of the embodiment can access a component processing position P2 located between a component receiving position P1 where each pallet 9 receives a component 2 from a component supply feeder 12 and a component transfer position P3 where each pallet 9 transfers the component 2 to the mounting unit 6 in a component mounting machine 1 in which multiple pallets 9 each capable of holding a component 2 rotate endlessly, and bends the leads of the component 2A at the component processing position P2 to lay the component 2A on its side.

This configuration improves the production efficiency of the component mounter 1.

In addition, in the component processing method of the embodiment, in a component mounting machine 1 in which a plurality of pallets 9 capable of holding components 2 rotate endlessly, a first component processing device 32 that can access a component processing position P2 located between a component receiving position P1 where each pallet 9 receives components 2 from a component supply feeder 12 and a component transfer position P3 where each pallet 9 transfers components 2 to a mounting unit 6 is used to bend the leads of component 2A at the component processing position P2 and lay the component 2A sideways.

This method improves the production efficiency of the component mounter 1.
