The bulk part supply device 30 is arranged at one end of the frame 40 in the front-rear direction. The discrete component supply device 32 is a device that aligns a plurality of scattered components and supplies the components in an aligned state. In other words, it is a device that aligns a plurality of parts in arbitrary postures in a predetermined posture and supplies the components in the predetermined posture.

The component supply device 32 is arranged at the other end of the frame 40 in the front-rear direction. The component supply device 30 has a tray type component supply device 78 and a feeder type component supply device 80 . The tray-type component supply device 78 is a device that supplies components placed on a tray 81 . The feeder-type component supply device 80 is a device that supplies components using a tape feeder 82 . The tape feeder 82, for example, separates the lead component from the taped component and supplies the separated lead component. The rails of the tape feeder 82 are fitted into the slots 88 formed on the upper surface of a feeder holding base 86 fixedly provided at the other end of the frame 40, so that the tape feeder 82 becomes a feeder. It is positioned and attached to the slot 88 of the holding base 86 so that it can be attached and detached with one touch by an operator without using a tool. A connector (not shown) is provided on the front end face of the tape feeder 82 , and the connector is formed on the feeder holding base 86 by mounting the tape feeder 82 on the feeder holding base 86 . is connected to a connector connecting portion (not shown). Thereby, the tape feeder 82 is electrically connected to the component mounting apparatus 10 and power is supplied to the tape feeder 82 . A plurality of slots 88 are formed in the feeder holder 86, and the tape feeder 82 is mounted in any one of the plurality of slots 88. As shown in FIG. The upper surface of the feeder holding base 86 is a horizontal surface, and a slot 88 is formed in the upper surface so as to extend in the Y direction. It is attached to the feeder holding base 86 in a posture extending vertically.

In the component mounting apparatus 10, the operation of mounting components is performed on the circuit board 12 held by the substrate conveying/holding device 22 by the above-described configuration. Various components can be mounted on the circuit board 12 by the component mounting apparatus 10. A case where a lead component (see FIG. 5) 100 is mounted on the circuit board 12 will be described below.

Specifically, the circuit board 12 is transported by the transport device 50 to the working position, and is fixedly held by the clamp device 52 at that position. Next, the imaging device 26 moves above the circuit board 12 and takes an image of the circuit board 12 . As a result, information regarding the positions of the pair of through holes (see FIG. 5) 102 formed in the circuit board 12 is obtained. Also, the bulk component supply device 30 or the component supply device 32 supplies the lead component 100 at a predetermined supply position. The lead component 100 includes a generally block-shaped component body 106 and two leads 108 extending in the same direction from the bottom surface of the component body 106, as shown in FIG. That is, the lead component 100 is a so-called radial lead component.

Then, one of the working heads 60 and 62 moves above the component supply position, and the pair of gripping claws 68 of the component holder 66 grips the component main body 106 of the lead component 100 . is held by the component holder 66 . Subsequently, the working heads 60 and 62 holding the lead component 100 are moved above the imaging device 28 , and the lead component 100 held by the component holder 66 is imaged by the imaging device 28 . This provides information about the tip positions of the pair of leads 108 . Subsequently, the working heads 60 and 62 holding the lead component 100 move above the circuit board 12, and the holding posture of the held component is changed to the position of the through hole 102 formed in the circuit board 12 and , the adjustment is made based on the information on the tip positions of the leads 108 of the lead component 100 held by the component holder 66 . At this time, the positions of the pair of through holes 102 formed in the circuit board 12 and the tip positions of the pair of leads 108 of the lead component 100 held by the component holder 66 are aligned in the vertical direction. , movement of the working heads 60 and 62 and adjustment of the holding posture are performed.

Then, when the working heads 60, 62 move so that the positions of the pair of through holes 102 and the tip positions of the pair of leads 108 match in the vertical direction, the working heads 60, 62 descend. Thereby, as shown in FIG. 5, the tip portions of the pair of lead components 100 are inserted into the pair of through holes 102 of the circuit board 12 . Then, after the pair of gripping claws 68 of the component holder 66 are separated and the held lead component 100 is released, the pusher 69 descends. As a result, the pusher 69 contacts the upper surface of the component body 106 of the lead component 100 and pushes the lead component 100 downward, thereby inserting the pair of leads 108 of the lead component 100 into the pair of through holes 102 to the root. be done. Thus, in the component mounting apparatus 10, the lead component 100 is mounted on the circuit board 12 by inserting the pair of leads 108 of the lead component 100 into the pair of through holes 102 of the circuit board 12. .

However, the leads 108 of the lead component 100 may be bent obliquely during the manufacturing process, when set on the tape feeder 82, or when separated from the taped component by the tape feeder 82. In such a case, as shown in FIG. 6, the distance between the tips of the pair of leads 108 of the lead component 100 and the distance between the pair of through-holes 102 of the circuit board 12 are different. 108 may not be able to be inserted into the pair of through holes 102 . In the lead component 100 shown in FIG. 6, the leading ends of a pair of leads are obliquely bent in directions away from each other, forming a V-shape.

In view of this, in the component mounting apparatus 10, a lead correcting device for correcting the posture of the pair of leads 108 of the lead component 100 is attached to the feeder holder 86 for attaching the tape feeder 82. there is Specifically, as shown in FIG. 7, the lead straightening device 110 is composed of a housing 112 and a lead straightening mechanism 114 . The housing 112 has substantially the same shape as the housing of the tape feeder 82, and the bottom surface of the housing 112 is provided with a rail (not shown) having the same shape as the rail provided on the bottom surface of the tape feeder 82. It is Therefore, by fitting the rail provided on the lower surface of the housing 112 into the slot 88 of the feeder holding table 86, the lead straightening device 110 can be inserted into the slot 88 of the feeder holding table 86 so that the operator can use the tool. It is positioned and mounted so that it can be attached and detached with one touch without using a That is, by mounting the lead correction device 110 in the slot 88 , the lead correction device 110 is mounted on the feeder holder 86 in a posture extending in the Y direction, like the tape feeder 82 . A connector 116 having the same shape as the connector of the tape feeder 82 is arranged on the front end face of the housing 112 . , is connected to a connector connecting portion formed on the feeder holding base 86 . As a result, the lead straightening apparatus 110 is electrically connected to the component mounting apparatus 10, and power is supplied to operate the lead straightening apparatus 110. FIG.

The upper end surface of the housing 112 is open, and the lead correction mechanism 114 is built in the upper end portion of the housing 112 with the upper end surface of the lead correction mechanism 114 exposed through the opening. The lead correction mechanism 114 has a base 120, a support stand 122, a slide mechanism 124, a clamp mechanism 126, and a cover 128, as shown in FIG. The base 120 has a generally rectangular plate shape and is arranged in a posture extending in the Y direction. The support base 122 is generally desk-shaped and fixed to the upper surface of the base 120 .

The slide mechanism 124, as shown in FIG. 9, is composed of a piston 130 operated by air, a slide body 132, and a correction plate 134. It should be noted that the clamping mechanism 126 and the cover 128 are omitted in FIG. 9 in order to ensure the visibility of the slide mechanism 124 . The slide body 132 has a generally rectangular plate shape and is arranged on the upper surface of the support base 122 in a posture extending in the Y direction. Note that the upper surface of the slide body 132 is a horizontal plane. A rail 136 is provided on the upper surface of the support base 122 so as to extend in the Y direction, and the rail 136 supports the slide body 132 so as to be slidable in the Y direction. Further, the piston 130 is arranged in a posture extending in the Y direction on the rear side of the slide body 132 , and the tip of the piston rod 138 of the piston 130 is connected to the slide body 132 via the bracket 140 . Accordingly, the slide body 132 slides on the upper surface of the support base 122 in the Y direction by operating the piston 130 . Further, the correction plate 134 is bolted to the upper surface of the slide body 132, and as shown in FIG.

11 and 12, the clamping mechanism 126 includes a piston 150 operated by air, a connecting mechanism 152, a pair of support legs 154, a pair of movable clampers 156, and a pair of fixed clamps. and a clamper 158 . 11 and 12, the cover 128 is omitted in order to ensure visibility of the clamp mechanism 126. As shown in FIG. The piston 150 is disposed below the base 120 so as to extend vertically with a piston rod (not shown) directed upward. The connecting mechanism 152 is composed of a pair of arms (only one arm is shown in the figure) 160 and a pair of support blocks (only one support block is shown in the figure) 162. It is A through hole 164 is formed through the base 120 in the vertical direction, and the arm 160 extends through the through hole 164 in the vertical direction of the base 120 . The arm 160 is generally bent in a doglegged shape, and is swingably held by the base 120 at the bent portion of the arm 160 by a shaft 166 extending in the Y direction. Rails 168 are arranged on the upper surface of the base 120 so as to extend in the X direction, and a pair of support blocks 162 are supported by the rails 168 so as to be slidable in the X direction. Upper ends of the pair of arms 160 are connected to a pair of support blocks 162 . Also, the lower ends of the pair of arms 160 are connected to the piston rod of the piston 150 via brackets 170 .

With this structure, in the connecting mechanism 152, when the piston 150 extends, the bracket 170 rises and the lower ends of the pair of arms 160 also rise. At this time, each of the pair of arms 160 swings about the shaft 166 so that the upper ends of the pair of arms 160 approach each other. At this time, the pair of support blocks 162 connected to the upper ends of the pair of arms 160 slide in a direction toward each other. On the other hand, when the piston 150 contracts, the bracket 170 descends and the lower ends of the pair of arms 160 also descend. At this time, each of the pair of arms 160 swings about the shaft 166, thereby separating the upper ends of the pair of arms 160 from each other. At this time, the pair of support blocks 162 connected to the upper ends of the pair of arms 160 slide away from each other.

A pair of cutouts (only one cutout is shown in the figure) 172 is formed on both edges of the support base 122 in the X direction. It extends above the support base 122 through the pair of notches 172 . The upper ends of the pair of support blocks 162 extend slightly above the upper surface of the correction plate 134 of the slide mechanism 124 . A pair of movable clampers 156 are fixed to the upper surfaces of a pair of support blocks 162 extending upward from the support base 122 . A pair of support legs 154 are erected on the upper surface of the support table 122 so as to sandwich a pair of support blocks 162 extending upward from the support table 122 . The upper ends of the pair of support legs 154 are located at approximately the same height as the upper surfaces of the pair of movable clampers 156 . A pair of fixed clampers 158 are held by a pair of support legs 154 between the pair of movable clampers 156 so as to face the pair of movable clampers 156 .

With such a structure, in the clamping mechanism 126, the piston 150 is extended and the pair of support blocks 162 are slid in a direction approaching each other, so that, as shown in FIG. , a pair of movable clampers 156 approach a pair of fixed clampers 158 . On the other hand, when the piston 150 contracts and the pair of support blocks 162 slides away from each other, as shown in FIG. It is separated from the pair of fixed clampers 158 .

Grooves

176 and 178 corresponding to the wire diameter of the lead 108 are formed in the facing surfaces of the movable clamper 156 and the fixed clamper 158 so as to extend vertically. As the movable clamper 156 approaches the fixed clamper 158, the lead 108 is clamped between a groove 176 formed in the movable clamper 156 and a groove 178 formed in the fixed clamper 158, which will be described in detail later. . The

grooves

176 and 178 are positioned above the through hole 146 of the correction plate 134 when the movable clamper 156 approaches the fixed clamper 158 and clamps the lead. is formed in

Also, as shown in FIG. 8, the cover 128 is generally plate-shaped and bolted to the upper ends of the pair of support legs 154 . A plurality of insertion holes 180 penetrating vertically are formed in the cover 128 so as to vertically match the plurality of through holes 146 of the correction plate 134 of the slide mechanism 124 . The inner diameter of the insertion hole 180 is larger than the inner diameter of the through hole 102 formed in the circuit board 12, and as shown in FIG. Large enough to be inserted into hole 180 .

In the lead straightening device 110 having such a structure, the pair of leads 108 of the lead component 100 held by the component holder 66 are inserted into the pair of insertion holes 180 of the cover 128, and the pair of leads 108 are inserted. is clamped by the clamp mechanism 126 . The tips of the pair of leads 108 clamped by the clamp mechanism 126 are inserted into the through holes 146 of the correction plate 134 of the slide mechanism 124, and the correction plate 134 is moved by the operation of the piston 130. , the posture of the pair of leads 108 is corrected.

Specifically, when the lead component 100 is gripped by the pair of gripping claws 68 of the component holder 66, the working

head

60, 62 moves. By lowering the working heads 60 and 62 , the pair of leads 108 of the lead component 100 are moved out of the plurality of insertion holes 180 formed in the cover 128 of the lead straightening mechanism 114 of the lead straightening device 110 . It is inserted into a pair of insertion holes 180 corresponding to a pair of leads of the lead component. At this time, in the clamp mechanism 126 of the lead correction mechanism 114, the piston 150 is contracted, and the pair of movable clampers 156 are separated from the pair of fixed clampers 158, as shown in FIG. With the pair of leads 108 of the lead component 100 inserted into the pair of insertion holes 180 , the pair of gripping claws 68 are separated from each other to release the lead component 100 from being held by the component holder 66 . As a result, the pusher 69 of the component holder 66 descends. As a result, the lead component 100 is pushed downward by the pusher 69 from above, and the pair of leads 108 are inserted into the pair of insertion holes 180 to their roots as shown in FIG. At this time, the tips of the pair of leads 108 are inserted between the movable clamper 156 and the fixed clamper 158 into the pair of through holes 146 of the correction plate 134 located below the pair of insertion holes 180 . be. Even after the pair of leads 108 have been inserted into the pair of insertion holes 180 to their roots, the pusher 69 continues to press the lead component 100 downward. In other words, even after the pair of leads 108 are inserted into the pair of insertion holes 180 to the root, the lead component 100 is kept pressed by the pusher 69 .

When the pair of leads 108 are inserted into the pair of insertion holes 180 to their roots, the pistons 150 are actuated and extended, so that, as shown in FIG. Approach the fixed clamper 158 . Thereby, each of the pair of leads 108 is clamped between the groove 176 of the movable clamper 156 and the groove 178 of the fixed clamper 158 . That is, the pair of leads 108 are fixedly held by the clamp mechanism 126 . The bend position of the lead when the lead 108 is obliquely bent is statistically assumed in advance, and the position where the lead is clamped by the movable clamper 156 and the fixed clamper 158 is set to the bend position of the lead. , the heights of the movable clamper 156 and the fixed clamper 158 are set. That is, for example, when the lead 108 is obliquely bent, if the bend position of the lead is assumed to be 5 mm from the root of the lead, the movable clamper 156 and the fixed clamper 158 are positioned 5 mm below the upper surface of the cover 128. The lead straightening mechanism 114 is designed to do so. As a result, the lead inserted into the insertion hole 180 in the lead correction mechanism 114 is clamped by the clamp mechanism 126 at the bent position of the lead. Even when the lead is clamped by the clamping mechanism 126, the lead component 100 is kept pressed by the pusher 69. FIG. This allows the clamping mechanism 126 to properly clamp the pair of leads.

Then, when the pair of leads 108 inserted into the pair of insertion holes 180 are clamped by the clamp mechanism 126, the piston 130 operates in the slide mechanism 124 and the correction plate 134 slides. At this time, the correction plate 134 slides in one direction in the Y direction, for example, in the direction of the arrow in FIG. The amount of expansion and contraction of the piston 130 at that time, that is, the amount of sliding of the correction plate 134 in one direction in the Y direction is determined by It is set to slightly pass below the

grooves

176 and 178 of the movable clamper 156 and the fixed clamper 158 that clamp the . By setting the amount of sliding of the correction plate 134 in this manner, one lead 108a of the pair of leads 108 is linearly corrected.

Specifically, the pair of leads 108 inserted into the pair of through-holes 146 of the correction plate 134 by being pushed into the pushers 69 of the component holder 66 are bent in a V shape as shown in FIG. rice field. That is, the tips of the pair of leads 108 were bent outward and away from each other. 15, one lead 108a of the pair of leads 108 comes into contact with the inner wall surface defining the through hole 146, thereby causing the other lead 108a to slide. It bends slightly toward the lead 108b. That is, the leads 108a bent outward contact the inner wall surface defining the through hole 146 and are slightly bent inward. However, since the amount of inward bending of the lead 108a is very small, the lead 108a is straightened substantially straight. As described above, the Y direction in which the correction plate 134 moves is the horizontal direction perpendicular to the X direction, and the X direction is the direction in which the circuit board 12 is transported by the substrate transporting/holding device 22 . Therefore, the correcting plate 134 moves in a horizontal direction perpendicular to the X direction in which the circuit board 12 is transported by the substrate transporting/holding device 22 .

Next, after the correction plate 134 slides in one direction in the Y direction (the direction of the arrow in FIG. 15) by the operation of the piston 130, the correction plate 134 slides in the other direction in the Y direction, that is, Slide in the direction of the arrow in FIG. The amount of expansion and contraction of the piston 130 at that time, that is, the amount of sliding of the correction plate 134 in the other direction in the Y direction is determined by It is set to slightly pass below the

grooves

176 and 178 of the movable clamper 156 and the fixed clamper 158 that clamp the . By setting the amount of sliding of the correction plate 134 in this manner, the other lead 108b of the pair of leads 108 is linearly corrected.

Specifically, the other lead 108b of the pair of leads 108 was initially bent outward, but when the lead 108b comes into contact with the inner wall surface that defines the through hole 146, one of the leads 108 It bends slightly in the direction approaching the lead 108a. In other words, the outwardly bent lead 108b contacts the inner wall surface defining the through hole 146 and is slightly bent inwardly. However, since the amount of inward bending of the lead 108b is very small, the lead 108b is straightened substantially straight. When the correcting plate 134 slides in the direction of the arrow in FIG. 15, the through hole 146 is defined by sliding the correcting plate 134 in the direction of the arrow in FIG. The inner wall surfaces contact each other and are bent outward, but the amount of outward bending of the lead 108a is extremely small, so the lead 108a is maintained substantially straight.

Even when the posture of the pair of leads 108 is corrected by the operation of the piston 130, the lead component 100 is kept pressed by the pusher 69. FIG. Thereby, the posture of the pair of leads 108 can be appropriately corrected by sliding the correction plate 134 . That is, the pair of leads are clamped by the clamping mechanism 126 and the lead component 100 is pressed against the cover 128, thereby preventing the lead component from being displaced when the lead is corrected, thereby clamping the lead. can be properly corrected.

When the correction of the lead by the sliding of the correction plate 134 is completed, first, the pusher 69 of the component holder 66 releases the pressure of the lead component, and the pair of gripping claws 68 grips the component main body 106 of the lead component. be.

More specifically, the correcting plate 134a is formed with a plurality of through holes 146a at positions corresponding to the plurality of insertion holes 180a formed in the cover 128a, and the correcting plate 134b is formed in the cover 128b. A plurality of through holes 146b are formed at positions corresponding to the plurality of insertion holes 180b. That is, the cover 128a and the correction plate 134a correspond, and the cover 128b and the correction plate 134b correspond. Therefore, when the cover 128a is attached to the pair of support legs 154, the correction plate 134a is attached to the slide body 132, and when the cover 128b is attached to the pair of support legs 154, the correction plate 134b is attached.
