As shown in FIGS. 4 and 5, feeders 12A and 12B each include driving force transmission mechanisms 30A and 30B. Each of the driving force transmission mechanisms 30A and 30B is a mechanism for converting the driving force F1 by the feeder drive unit 32 shown in FIG. 5 into a driving force in a predetermined direction and transmitting the driving force.

The feeder drive unit 32 of this embodiment has a function of generating a driving force F1 that reciprocates back and forth, and is configured with, for example, an air cylinder. One feeder drive section 32 can be arranged corresponding to one slot 20.

A driving force transmission mechanism 30A connected to the feeder driving unit 32 converts the driving force F1 of the feeder driving unit 32 into a driving force F2 for conveying the component holding tape 5 toward the component supply position P1, and transmits the driving force F2. . A driving force transmission mechanism 30B connected to the feeder driving section 32 converts the driving force F1 of the feeder driving section 32 into a driving force F3 that reciprocates a movable guide 36 in the lateral direction B, which will be described later, and transmits the driving force F3.

As shown in FIGS. 4 and 5, the first component processing feeder 12B has a movable guide 36, and the second component processing feeder 12C has a fixed guide 38. The movable guide 36 is a member configured to be movable in the lateral direction B, and the fixed guide 38 is a member fixed to the second component processing feeder 12C.

FIG. 6A shows a first state (starting state). In the first state shown in FIG. 6A, the plate 35B of the driving force transmission mechanism 30B is in the most advanced state approaching the pallet 9, and the movable guide 36 is retracted from the component processing position P2 (in an unbent state). ).

When the plate 35B retreats from the first state shown in FIG. 6A by the driving force F1 of the feeder drive unit 32, it enters the second state shown in FIG. 6B.

In the second state shown in FIG. 6B, the movable guide 36 of the first component processing feeder 12B does not move and maintains a state where it is retracted from the component processing position P2. On the other hand, in the component conveyance feeder 12A, the driving force F1 is converted into a driving force F2 and transmitted, so that the component holding tape 5 and the component 2 are fed by one pitch.

When the plate 35B further retreats from the second state shown in FIG. 6B by the driving force F1 of the feeder drive unit 32, it enters the third state shown in FIG. 6C.

In the third state shown in FIG. 6C, the driving force F1 is converted into the driving force F3 in the first component processing feeder 12B and transmitted to the movable guide 36, so that the movable guide 36 approaches the component 2 at the component processing position P2. It moves in the horizontal direction B as shown in FIG. Thereby, the part 2 is bent.

When transitioning from the third state shown in FIG. 6C to the fourth state shown in FIG. 6D, the driving force F1 of the feeder drive unit 32 acts in the opposite direction. As shown in FIG. 6D, the driving force F1 advances the plate 35B.

When transitioning to the fourth state shown in FIG. 6D, a driving force F3 in the opposite direction acts on the movable guide 36, and the movable guide 36 moves in the lateral direction B so as to retreat from the component processing position P2.

When the plate 35B moves further from the fourth state shown in FIG. 6D, it returns to the first state shown in FIG. 6A.

The state of the first component processing feeder 12B changes in the order of the first state, the second state, the third state, and the fourth state, and this state transition occurs as the driving force F1 of the reciprocating motion continuously acts. repeat.

7A to 7D are plan views for explaining the operations of the component conveyance feeder 12A and the first component processing feeder 12B, respectively.

7A corresponds to the first state of FIG. 6A, FIG. 7B corresponds to the second state of FIG. 6B, FIG. 7C corresponds to the third state of FIG. 6C, and FIG. 7D corresponds to the third state of FIG. 6D. It corresponds to 4 states.

In the first state and second state shown in FIGS. 7A and 7B, the movable guide 36 is in a state retracted from the transport path TR, and as the movable guide 36 moves to the second state shown in FIG. 7B, the component holding tape 5 and the component 2 is sent in the transport direction A by one pitch.

When transitioning to the third state shown in FIG. 7C, the movable guide 36 moves forward toward the transport path TR, and the lead of the component 2 at the component processing position P2 is bent.

In the fourth state shown in FIG. 7D, the movable guide 36 retreats from the transport path TR, and then returns to the first state shown in FIG. 7A.

Here, the bending operation of the component 2 by the movable guide 36 and the fixed guide 38 and the detailed configuration will be explained using FIGS. 8A and 8B. 8A and 8B are perspective views for explaining the bending operation, with FIG. 8A showing the state before bending, and FIG. 8B showing the state after bending.

As shown in FIGS. 8A and 8B, the movable guide 36 has a contact plate 40, and the fixed guide 38 has a contact plate 42.

The contact plate 40 is a plate-shaped member having a shape that protrudes in the lateral direction B toward the component 2 at the component processing position P2. The contact plate 42 is a plate-shaped member that protrudes upward along the height direction H. Both the contact plates 40 and 42 are provided at positions overlapping the leads of the component 2 in the height direction H. The height position of the upper end of the contact plate 42 is set lower than the height position of the contact plate 40.

As shown in FIG. 8B, when the movable guide 36 moves forward, the contact plate 40 contacts the lead of the component 2 and pushes the lead of the component 2 to a position beyond the contact plate 42. As shown in FIG. The lead of the component 2 is pressed against the fixed guide 38 at a location below the contact plate 42, and is bent approximately 90 degrees while being supported by the fixed guide 38. By combining the movable guide 36 and the fixed guide 38 in this manner, the leads of the component 2 can be bent with high precision.

Below the contact plate 40 in the movable guide 36, another contact part/contact plate may be provided for pressing the leads of the component 2 against the fixed guide 38. Damage to the lead or body of the component 2 may be suppressed by providing a biasing force such as a spring to the contact portion.

Next, the operation of transferring the component 2 from the component transport feeder 12A to the pallet 9 will be described using FIGS. 9A, 9B, 10A, 10B, 11A, 11B, 12A, and 12B. 9A, FIG. 9B, FIG. 10A, FIG. 10B, FIG. 11A, FIG. 11B, FIG. 12A, and FIG. 12B are perspective views for explaining the delivery operation of the component 2 and its related configuration, respectively.

9A, FIG. 10A, FIG. 11A, and FIG. 12A are perspective views seen from above, and FIG. 9B, FIG. 10B, FIG. 11B, and FIG. 12B are perspective views seen from below. 9A and 9B correspond to the first state, FIGS. 10A and 10B correspond to the second state, FIGS. 11A and 11B correspond to the third state, and FIGS. 12A and 12B correspond to the second state. It corresponds to 4 states.

As shown in FIGS. 9A, 10A, 11A, and 12A, the pallet 9 of this embodiment has a plurality of pallet claws 44. The pallet claws 44 are composed of a pair of opening/closing claws capable of holding the lead of the component 2 transported to the component supply position P1. The pallet claw 44 is provided with a recess 46, and when the engaging portion 48 of the first component processing feeder 12B comes into contact with the recess 46, the pallet claw 44 operates to open. The pallet claw 44 is always biased to the closed position and moves to the open position only when the engaging portion 48 comes into contact with it. The engaging portion 48 is connected to the aforementioned driving force transmission mechanism 30A, and the driving force is applied so that the engaging portion 48 moves forward toward the recess 46 of the pallet claw 44 in a second state (FIGS. 10A and 10B), which will be described later. communicated.

As shown in FIGS. 9B, 10B, 11B, and 12B, the component conveyance feeder 12A includes a tape cutting member 50. The tape cutting member 50 is a member for cutting the component holding tape 5 at a position upstream of the component transport position P1. By cutting the component holding tape 5, the component holding tape 5 delivered to the pallet claws 44 can be transported by the pallet 9.

The tape cutting member 50 has a pair of blades 52 that can be opened and closed. The pair of blades 52 are configured to be rotatable between an open position and a closed position, and are constantly biased toward the open position. The tape cutting member 50 is connected to the aforementioned driving force transmission mechanism 30A, and a driving force is transmitted to the tape cutting member 50 so as to move it to the closed position in a third state (FIGS. 11A and 11B), which will be described later.

When the first state shown in FIGS. 9A and 9B shifts to the second state shown in FIGS. 10A and 10B, the engaging portion 48 moves forward and contacts the pallet claw 44, and the pallet claw 44 moves to the open position. . This makes it possible to accept the lead of component 2. At the same time, the component holding tape 5 and the component 2, which had stopped before the component supply position P1, are fed by one pitch in the transport direction A, so that the lead of the leading component 2 is placed between the pair of pallet claws 44. be done.

When the second state shown in FIGS. 10A and 10B shifts to the third state shown in FIGS. 11A and 11B, the engaging portion 48 retreats and the pallet claw 44 returns to the closed position. As a result, the lead of the component 2 is held between the pallet claws 44. At the same time, the tape cutting member 50 is driven to move from the open position to the closed position, and the component holding tape 5 is cut at a position upstream of the component supply position P1. As a result, the component 2 held by the pallet claws 44 and the component holding tape 5 become independent, and can be transported together with the pallet 9 along the rotational direction X1.

When transitioning to the fourth state shown in FIGS. 12A and 12B, the pallet 9 moves in the rotational direction X1 to transport the component 2, and the tape cutting member 50 returns to the open position. Thereafter, the state returns to the first state shown in FIGS. 9A and 9B.

By repeating the operation of sequentially transitioning to the first state, second state, third state, and fourth state explained using FIGS. 6A to 12B, the pitch feeding operation of the part 2 and the machining operation (lead (folding operation) and the delivery operation of the parts 2 to the pallet 9 can be performed in parallel. In this way, parts 2 that have undergone predetermined processing can be sequentially supplied to the pallet 9 at the parts supply position P1.

Next, the state detection sensor 56 for detecting the processing state of the component 2 will be explained using FIG. 13.

FIG. 13 is a perspective view including the state detection sensor 56 and its peripheral configuration.

As shown in FIG. 13, a component inspection position P3 for inspecting the processing state of the component 2 is set upstream of the component supply position P1 in the transport direction A. A state detection sensor 56 is provided at the component inspection position P3.

The state detection sensor 56 is a sensor for detecting the processing state of the component 2. In this embodiment, a transmission type optical sensor is used as the state detection sensor 56 for detecting whether the lead of the component 2 is properly bent as the processing state of the component 2.

The state detection sensor 56 shown in FIG. 13 includes a light emitting section 58, a light receiving section 60, and a bracket 62.

The light emitting section 58 is a member that emits light such as infrared light toward the light receiving section 60 located at a position opposite to the transport path TR. The light receiving section 60 is a member that receives light emitted from the light emitting section 58. In this embodiment, the light emitting unit 58 is arranged on the side closer to the second component processing feeder 12C with respect to the transport route TR, and the light receiving unit 60 is arranged on the side closer to the first parts processing feeder 12B with respect to the transport route TR. Ru.

The height position of the light emitted by the light emitting section 58 is set to a position where the lead overlaps the body portion of the component 2 in an unbent state. According to such a height setting, when the component 2 is bent normally, the light from the light emitting section 58 is not blocked by the component 2 and reaches the light receiving section 60; If the light emitting part 58 is not bent properly, the light from the light emitting part 58 is blocked by the body part of the component 2 and does not reach the light receiving part 60. Therefore, it is possible to detect whether or not the component 2 is folded normally, depending on whether or not the light receiving section 60 receives the light at the timing when the light emitting section 58 is emitting light.

Both the light emitting section 58 and the light receiving section 60 are electrically connected to the control section 16 (FIG. 1). The light emitting section 58 is controlled to emit light at a predetermined timing or at all times, and the light receiving section 60 transmits a signal indicating whether or not light is received to the control section 16.

The bracket 62 is a member for fixing the light emitting section 58 and the light receiving section 60. The bracket 62 of this embodiment fixes the light emitting section 58 and the light receiving section 60 to the second component processing feeder 12C. As shown in FIG. 13, the bracket 62 is bent upward and extends from the second component processing feeder 12C so as to straddle the component 2 at the component inspection position P3. is fixed, and the light receiving section 60 is fixed at a position close to the first component processing feeder 12B.

By installing the state detection sensor 56 on the second component processing feeder 12C having the fixed guide 38, disturbances such as vibrations can be reduced compared to the case where the state detection sensor 56 is installed on the first component processing feeder 12B having the movable guide 36. The state of the component 2 can be detected.

As described above, according to the component mounter 1 of this embodiment, in addition to the function of transporting the component 2 in the transport direction A by the component transport feeder 12A, by attaching the component processing feeders 12B and 12C, the lead of the component 2 is A function to fold can be added. Thereby, processing functions such as bending the leads of the component 2 can be added while using the existing component transport feeder 12A, and the method of supplying the component 2 can be easily changed.

As shown in FIGS. 4 and 5, the plurality of slots 20 of the feeder base 18 have a mutually common shape, and the mounting parts 22A to 22C, 24A to 24C of the feeders 12A to 12C also have a mutually common shape.
