Description

Technical Field

[0001] The present invention relates to a component supply device for conveying and storing components on a carrier belt and supplying components to a component outlet, and a component mounting device for mounting the components supplied by the component supply device on a substrate. Background Technology

[0002] Conventionally, as a component supply device that supplies components to a component mounting device that picks up components using a mounting head and mounts them onto a substrate, a belt feeder is known to transport and store a carrier belt containing components and supply components to a component take-off outlet. The belt feeder has a transport path in its main body, which is slidably mounted to a feeder mounting section of the component mounting device, guiding the transport of the carrier belt from an upstream portion to a downstream portion. A portion of the downstream portion of the transport path is covered by a belt cover. A component take-off outlet is provided in the belt cover. A sprocket provided in the main body rotates while engaging with a feed hole of the carrier belt located in the area covered by the belt cover, thereby transporting the carrier belt. A discharge path for discharging the carrier belt is provided downstream of the component take-off outlet in the transport path. The carrier belt entering from the inlet (discharge path inlet) of the discharge path is discharged from the outlet (discharge path outlet) located below the discharge path inlet.

[0003] Such a component supply device has a positioning pin (positioning pin) at the front end of the main body (the downstream end of the carrier belt flow). The positioning pin is inserted into a positioning hole (insertion hole) formed in the feeder assembly due to the sliding assembly of the main body. With the positioning pin inserted into the insertion hole, the component supply device is not only positioned relative to the feeder assembly, but also fixed relative to it. Therefore, even if the component supply device vibrates due to the excitation force generated during the operation of the component mounting device, the wobbling of the component dispensing outlet of the component supply device is suppressed. Therefore, component dispensing errors are less likely to occur (for example, see Patent Document 1 below).

[0006] Patent Document 1: International Publication No. 2014 / 147799 Summary of the Invention

[0007] However, in recent years, the miniaturization of components has led to an increase in component removal errors caused by vibrations in the component supply device. To suppress the amplitude of vibrations in the component supply device during excitation, it is preferable to position the locating pin near the height of the component removal outlet. However, a conveyor belt discharge path is located near the height of the component removal outlet. Therefore, in the past, it was necessary to position the locating pin at a location much lower than the component removal outlet.

[0008] Therefore, the object of the present invention is to provide a component supply device and a component mounting device that can stably supply components by setting the positioning pin at a position close to the height of the component take-out port.

[0009] The component supply device of the present invention is assembled to the assembly part of a component mounting device that mounts components on a substrate, and transports and stores a carrier belt containing components and supplies components to a component take-off outlet. The component supply device includes: a main body having a transport path for guiding the transport of the carrier belt and a discharge path for discharging the carrier belt from the transport path, and is slidably mounted to the assembly part; a belt cover having a component take-off outlet and covering the upper part of a downstream portion of the transport path; a transport part having a sprocket that engages with a feed hole of the carrier belt located in a predetermined section of the transport path covered by the belt cover, and transports the carrier belt by rotating the sprocket; and a first positioning pin assembled to the main body and inserted into a first insertion hole for positioning formed in the assembly part as the main body slides and is mounted to the assembly part.

[0010] The discharge path has a discharge path inlet located downstream of the component take-out outlet and closer to the component take-out outlet than the first locating pin, and a discharge path outlet located below the first locating pin, and guides the carrier belt entering from the discharge path inlet to the discharge path outlet. The first locating pin is mounted on the main body at a position higher than the rotation center of the sprocket.

[0011] The component mounting device of the present invention removes a component from a carrier belt containing components and mounts it on a substrate. The component mounting device includes: a component supply device that transports the carrier belt and supplies components to a component take-off port; an assembly section that is equipped with the component supply device; and a component mounting section that removes the component from the component supply device mounted on the assembly section and mounts it on the substrate.

[0012] The component supply device includes: a main body having a transport path for guiding the transport of a carrier belt and a discharge path for discharging the carrier belt from the transport path, and sliding towards and being mounted to an assembly part; a belt cover having a component outlet and covering the upper part of a downstream portion of the transport path; a transport part having a sprocket that engages with a feed hole of the carrier belt located in a predetermined section of the transport path covered by the belt cover, and transporting the carrier belt by rotating the sprocket; and a first positioning pin mounted to the main body and inserted into a first insertion hole for positioning formed in the assembly part as the main body slides towards and is mounted to the assembly part.

[0013] The discharge path has a discharge path inlet located downstream of the component take-out outlet and closer to the component take-out outlet than the first locating pin, and a discharge path outlet located below the first locating pin, and guides the carrier belt entering from the discharge path inlet to the discharge path outlet. The first locating pin is mounted on the main body at a position higher than the rotation center of the sprocket.

[0014] According to the present invention, by redesigning the positional relationship between the discharge path of the carrier tape and the positioning pin, the positioning pin of the component supply device can be set at a position close to the height of the component take-out port, thereby enabling stable component supply.

[0038] (Implementation Method 1)

[0039] Figure 1 This is a side view of the main part of the component mounting device 1 in Embodiment 1 of the present invention.

[0040] exist Figure 1 In this configuration, the component mounting device 1 has a base cover 12 above the base 11. A working space 13 is formed between the upper surface of the base 11 and the base cover 12. A substrate transport section 14 equipped with a pair of belt conveyors 14a is provided on the upper surface of the base 11. Figure 1The direction perpendicular to the paper surface is the transport direction of the substrate KB, and the pair of belt conveyors 14a extend along this transport direction. Within the workspace 13, a mounting head 16, which can move freely via a head moving mechanism 15, is provided. The mounting head 16 has multiple suction nozzles 16N extending downwards.

[0041] Hereinafter, the transport direction of the substrate KB transported by the substrate transport unit 14 will be defined as the X direction. Furthermore, the direction orthogonal to the X direction in the horizontal plane will be defined as the Y direction, and the vertical direction will be defined as the Z direction. Additionally, axes extending along the X, Y, and Z directions will be defined as the X-axis, Y-axis, and Z-axis, respectively.

[0042] exist Figure 1 In the middle, a trolley 17 is connected to the end of the base 11 on the Y-axis. A feeder assembly section 18 (assembly section) is provided on the trolley 17. A plurality of feeders 19 (component supply devices) are arranged in the feeder assembly section 18 in an X-direction arrangement.

[0043] The belt feeder 19 functions as a component supply device in the component loading device 1. In the belt feeder 19, the component take-out outlet 19K is located within the working space 13. The belt feeder 19 pulls and transports the carrier belt CT from the reel RL mounted on the trolley 17, thereby supplying component BH (see reference) to the component take-out outlet 19K. Figure 2 ).

[0044] The component mounting device 1 uses the substrate transport unit 14 to transport the substrate KB from an unshown device (such as a solder printer or other component mounting device) and positions it in a specified working position.

[0045] The mounting head 16 functions as a component mounting unit, repeatedly performing a component mounting cycle by moving it with the aid of the head moving mechanism 15. The component mounting cycle includes the action of picking up the component BH supplied by the conveyor 19 to the component take-out port 19K, and the action of mounting the picked-up component BH onto the substrate KB. After mounting the component BH onto the substrate KB by repeatedly performing the component mounting cycle, the substrate transport unit 14 moves the substrate KB to the next device (e.g., another component mounting device, inspection machine, or reflow oven).

[0046] In the component mounting device 1 with such a structure, in Embodiment 1, the structure of the belt feeder 19 and the feeder assembly 18 has certain characteristics, which will be described below. First, the belt feeder 19 will be described as the carrier belt CT that serves as the supply medium for component BH.

[0047] Figure 2 This is a perspective view of a portion of the carrier CT used in the component mounting device 1 of Embodiment 1 of the present invention. Figure 2In this structure, the carrier tape CT is formed by attaching a top tape TT to the upper surface of the base tape BT. On the base tape BT, rows of recessed pockets PK that house components BH and rows of feed holes SH that penetrate the base tape BT along the thickness direction are arranged in a row along the long side of the base tape BT.

[0048] The top band TT is composed of a membrane-like band member. The top band TT is a strip-shaped member extending along the long side of the base band BT and is attached to the base band BT in a manner that covers the rows of recessed pockets PK. Due to the top band TT, the components BH within each recessed pocket PK are housed (sealed) within the recessed pocket PK.

[0049] Next, the feeder assembly section 18 will be described. Figure 3A This is a side sectional view of the feeder assembly 18 of the component mounting device 1 in Embodiment 1 of the present invention. Figure 3B This is a rear view of the feeder assembly 18 provided in the component mounting device 1 according to Embodiment 1 of the present invention.

[0050] exist Figure 3A as well as Figure 3B In this design, the feeder assembly 18 has a horizontal base portion 21. Multiple rib-shaped guide portions 22 are provided on the upper surface of the base portion 21. Each guide portion 22 has a shape extending along the Y direction. A slot 22S for sliding and mounting the belt feeder 19 is provided on the upper surface of the base portion 21 between adjacent guide portions 22. In other words, multiple slots 22S, whose positions are defined by the guide portions 22, are formed on the upper surface of the base portion 21. Figure 3B ).

[0051] exist Figure 3A as well as Figure 3B In this configuration, a wall-shaped first reference member 23 and a second reference member 24c are provided at the front end of the base portion 21 (the end near the substrate transport portion 14). The first reference member 23 is configured to extend upward from the front end of the base portion 21. The second reference member 24 is configured to extend upward from a position rearward of the first reference member 23. The height of the first reference member 23 is approximately the same as the height of the feeder 19 mounted on the feeder assembly portion 18. The height of the second reference member 24 is approximately half the height of the first reference member 23.

[0052] like Figure 3A As shown, a discharge opening 21K that extends vertically through the base portion 21 is provided between the first reference member 23 and the second reference member 24.

[0053] exist Figure 3A as well as Figure 3BIn the first reference member 23, a plurality of first insertion holes 25 are provided on the upper part in an X-direction arrangement. On the other hand, a plurality of second insertion holes 26 are provided on the lower part of the second reference member 24 in an X-direction arrangement. The first insertion holes 25 penetrate the first reference member 23 in the thickness direction (Y direction). The second insertion holes 26 penetrate the second reference member 24 in the thickness direction (Y direction).

[0054] Figure 13 This is a cross-sectional view of a portion of the feeder in Embodiment 1 of the present invention. The positions of the first insertion hole 25 and the second insertion hole 26 in the X direction correspond to the slots 22S formed in the base portion 21, respectively. The second insertion hole 26 is located at a lower position than the first insertion hole 25. The first insertion hole 25 has an elongated shape with a longer vertical dimension (see reference). Figure 13 On the other hand, the second insertion hole 26 has a perfect circular shape.

[0055] exist Figure 3A as well as Figure 3B In the base portion 21, a downwardly extending extension portion 27 is formed at the rear end. On the rear surface of the extension portion 27, a plurality of clamping portions 28 and a plurality of communication connectors 29 are respectively provided in an X-direction arrangement.

[0056] The clamping part 28 and the communication connector 29 are respectively disposed at positions corresponding to the slots 22S formed in the base part 21. The communication connector 29 is located below the clamping part 28. Each clamping part 28 is a cam follower having a rotation axis parallel to the X-axis, and is fitted to one end of a pair of support members 28S protruding from the extension part 27. The support members 28S apply downward force to the clamping part 28 by means of an elastic member (not shown) built into the extension part 27.

[0057] Next, the feeder 19 will be described. Figure 4 This is a side view of the component mounting device 1 with a feeder 19 in Embodiment 1 of the present invention. Figure 5A This is a side view of a portion of the feeder 19 in Embodiment 1 of the present invention. Figure 5B This is a side view of a portion of the feeder 19 in Embodiment 1 of the present invention. Figure 6 This is a side view of a portion of the feeder 19 included in the component mounting device according to Embodiment 1 of the present invention.

[0058] exist Figure 4 The feeder 19 includes a main body 31, a transport part 32, a first positioning pin 33, a second positioning pin 34, a clamping member 35, and a connector 36.

[0059] exist Figure 4In the middle, the main body 31 is composed of the main frame 41, the front end component 42, and the front end component fastener 43.

[0060] The main body 31 has a transport path 31L for guiding the transport of the carrier CT and a discharge path 46 for discharging the carrier CT from the transport path 31L. In addition, a cover 44 and a cover pressing member 45 are assembled on the main body 31.

[0061] The main frame 41 is a plate-like structure that extends along the YZ plane, and has a length in the Y direction that is longer than its length in the Z direction. The width dimension (X direction) of the main frame 41 is slightly larger than the width dimension of the carrier tape CT.

[0062] exist Figure 4 In the main frame 41, a sliding part 41S extending in the Y direction is provided on the lower front surface. The sliding part 41S is inserted into the slot 22S of the feeder assembly 18 and slides, thereby mounting the main frame 41 (i.e. with feeder 19) to the feeder assembly 18.

[0063] exist Figure 4 In the main frame 41, a transport path 31L is provided for guiding the transport of the CT scanner. The transport path 31L extends from the rear end to the front end of the main frame 41, and the rear end and front end of the transport path 31L are respectively provided with openings relative to the main frame 41. The rear opening of the transport path 31L is called the belt inlet 31A, and the front opening of the transport path 31L is called the belt outlet 31B.

[0064] The belt inlet 31A is located at the lower rear end of the main frame 41, and the belt outlet 31B is located at the upper front end of the main frame 41. The transport path 31L is formed as follows: In its upstream section, the transport path 31L extends approximately horizontally from the belt inlet 31A towards the downstream end; then it slopes (uphill) in the middle of the main frame 41; and finally extends approximately horizontally in its downstream section, where the slope ends, to reach the belt outlet 31B. The downstream section of the transport path 31L ( Figure 5A as well as Figure 5B The defined section (open section KK) shown in the diagram is open to the top of the main frame 41. The open section KK of the transport path 31L is approximately horizontal. It should be noted that the "downstream section" of the transport path 31L is defined as the area that includes at least the open section KK.

[0065] exist Figure 4 , Figure 5A , Figure 5B as well as Figure 6 In this configuration, the front-end component 42 is assembled to the end (front end) of the main frame 41. Specifically, a front-end component fastener 43 is installed on the upper front end of the main frame 41. The front-end component 42 is installed at the front end of the front-end component fastener 43.

[0066] Figure 7A This is a cross-sectional view of the discharge path 46 provided by the feeder 19 in Embodiment 1 of the present invention. Figures 7B to 7D This is a cross-sectional view of the discharge path 46 provided by the feeder 19 in a modified embodiment 1 of the present invention.

[0067] like Figure 7A ( Figure 7A yes Figure 6 As shown in the sectional view (AA) in the figure, the front end member fixing member 43 is composed of a pair of plate-shaped members arranged at intervals along the X direction. In this way, the front end member 42 is positioned forward and away from the front end of the main body frame 41 in a manner that is fixed by the front end member fixing member 43.

[0068] like Figure 6 as well as Figure 7A As shown, a space is formed in front of the main frame 41, comprising the main frame 41, the front end member 42, and the front end member fixing member 43. This space serves as a discharge path 46 for guiding the discharge of the CT scanner. The inlet of the discharge path 46, namely the discharge path inlet 46A (which is also the belt outlet 31B of the transport path 31L), is located downstream of the transport path 31L from the component take-out outlet 19K. The outlet of the discharge path 46, namely the discharge path outlet 46B, is located below the discharge path inlet 46A.

[0069] Here, as Figure 5A , Figure 5B as well as Figure 6 As shown, the opening at the upper end of the discharge path 46, namely the discharge path inlet 46A, is located downstream of the component take-out outlet 19K. Therefore, the carrier tape CT taken out from the tape outlet 31B of the transport path 31L is guided by the discharge path 46 after entering the discharge path inlet 46A and discharged from the discharge path outlet 46B below the discharge path 46.

[0070] The discharge path 46 has a discharge path inlet 46A located closer to the component outlet 19K than the first locating pin 33, and a discharge path outlet 46B located lower than the first locating pin 33. The discharge path 46 is configured to guide the carrier tape CT entering from the discharge path inlet 46A to the discharge path outlet 46B. By making the discharge path 46 meander downwards towards the front end (front end member 42) of the main body 31 in this way, the first locating pin 33 can be installed at the highest possible position on the front end.

[0071] In this way, the belt feeder 19 in Embodiment 1 is configured such that the discharge path 46 is provided between the main frame 41 and the front end member 42. Furthermore, the discharge path 46 has a discharge path inlet 46A located downstream of the component take-out outlet 19K and near the transport path 31L, and a discharge path outlet 46B located below the discharge path inlet 46A. The discharge path 46 is configured to guide the carrier belt CT entering from the discharge path inlet 46A towards the discharge path outlet 46B.

[0072] In this embodiment 1, the discharge path 46 is formed by the space enclosed by the main frame 41, the front end member 42, and the front end member fixing member 43, but it is not limited to this. The discharge path 46 can be formed in front of the main frame 41, and may not have the front end member 42 and the front end member fixing member 43. Therefore, for example, it may have the following structure: Figure 7B As shown, a discharge path 46 is formed at the front end of the main frame 41, but it does not have both a front end member 42 and a front end member fixing member 43. Alternatively, it can also be structured as follows: Figure 7C As shown, a discharge passage 46 with an opening on one side is provided at the front end of the main frame 41, and a cover member 47 is installed on the open side of the discharge passage 46. Alternatively, the structure can be as follows: Figure 7D As shown, a discharge path 46 is formed in the front end member 42. The front end member 42 with the discharge path 46 is installed at the front end of the main frame 41, so that the front end member fastener 43 is not required.

[0073] exist Figure 4 , Figure 5A , Figure 5B as well as Figure 6 In the middle, the cover 44 is disposed on the upper part of the front region of the main frame 41. The cover 44 has a groove-shaped cross-section that opens downward. The aforementioned component outlet 19K is provided on the top part 44T of the cover 44.

[0074] exist Figure 5A as well as Figure 6 In this configuration, the cover 44 is horizontally mounted on the upper front of the main body 31, covering the open section KK, which is part of the downstream portion of the transport path 31L. The rear end of the cover 44 is fitted to the main frame 41 via a first axis 44J parallel to the X-axis. Thus, by swinging around the first axis 44J, the open section KK can be opened upwards. Figure 5B Hereinafter, the position of the cover 44 covering the open interval KK will be referred to as the normal position. Figure 5A The position that will make the open interval KK open is called the open position. Figure 5B ).

[0075] Figure 8AThis is a top view of a part of the component mounting device 1 in Embodiment 1 of the present invention. Figure 8B This is a side view of a part of the component mounting device 1 in Embodiment 1 of the present invention. Figure 9 This is a partial cross-sectional side view showing the feeder 19 and the feeder assembly 18 together in Embodiment 1 of the present invention.

[0076] exist Figure 5A , Figure 5B , Figure 6 , Figure 8A as well as Figure 8B In the middle, the covered pressing member 45 is provided at the upper end of the front end member 42. The lower end of the covered pressing member 45 is assembled to the front end member 42 via a second axis 45J parallel to the X-axis, and is configured to swing freely about the second axis 45J. Figure 5A as well as Figure 5B ).

[0077] exist Figure 5A , Figure 5B , Figure 8A as well as Figure 8B In this configuration, a roller 45R is mounted on the upper end of the cover pressing member 45. When the cover 44 is in its normal position, the cover pressing member 45 causes the roller 45R to abut against the front end of the cover 44 from above. At this time, the cover pressing member 45 uses the force of the spring member 45S provided between itself and the front end member 42 to press the roller 45R against the cover 44, thereby pressing the cover 44 against the main body 31. Figure 5A Here, when the belt cover 44 is moved from its normal position to the open position, the operator lifts the roller 45R with his fingers, causing the belt cover pressing member 45 to swing about the second axis 45J. Figure 5B Arrow P shown.

[0078] The transport unit 32 is a mechanism that transports the carrier CT within the transport path 31L forward. For example... Figure 4 as well as Figure 6 As shown, the transport unit 32 has multiple sprockets (positioning sprocket 51, transport sprocket 52, and discharge sprocket 53) disposed at the upper front of the main frame 41. The positioning sprocket 51 and discharge sprocket 53 are sprockets that engage with the feed hole SH of the carrier belt CT located in the open section KK of the transport path 31L. The transport sprocket 52 is a sprocket that engages with the feed hole SH of the carrier belt CT located upstream of the open section KK of the transport path 31L.

[0079] like Figure 8A as well as Figure 8BAs shown, the positioning sprocket 51 causes the outer peripheral pin (positioning sprocket outer peripheral pin 51P) to engage with the feed hole SH in the carrier belt CT within the open section KK, located upstream of the component take-out outlet 19K, and rotate in a pitching motion. As a result, the carrier belt CT is moved, and the concave bag PK is positioned at the component take-out outlet 19K.

[0080] like Figure 8A As shown, a clearance opening 44K is provided through the top surface 44T of the cover 44 in a manner parallel to the component outlet 19K along the thickness direction. The uppermost outer peripheral pin of the positioning sprocket outer peripheral pin 51P is configured to pass through the clearance opening 44K of the cover 44, which is located in its normal position. Figure 8A Therefore, interference between the outer peripheral pin 51P of the positioning sprocket and the cover 44 is suppressed.

[0081] exist Figure 4 as well as Figure 6 In this configuration, the transfer sprocket 52 is located upstream of the positioning sprocket 51. The transfer sprocket 52 transfers the carrier CT to the positioning sprocket 51 by tilting and rotating its outer peripheral pin in conjunction with the feed hole SH of the carrier CT within the transfer path 31L.

[0082] exist Figure 6 In this device, a belt processing member 44S is provided on the lower surface of the top part of the cover 44. The belt processing member 44S is a member that performs processing to expose the component BH inside the concave bag PK by cutting the top belt TT from the carrier belt CT transferred from the transport sprocket 52 to the positioning sprocket 51. By processing the top belt TT of the carrier belt CT with the belt processing member 44S, the concave bag PK, which is positioned at the component removal outlet 19K by the positioning sprocket 51, is in a peeled-out state. Therefore, the mounting head 16 can remove (pick up) the component BH using the suction nozzle 16N.

[0083] exist Figure 4 , Figure 6 , Figure 8A as well as Figure 8B In this configuration, the discharge sprocket 53 is located downstream of the positioning sprocket 51. The discharge sprocket 53 receives the carrier belt CT from the transport path 31L from the positioning sprocket 51 and transports (discharges) the carrier belt CT from the belt outlet 31B to the discharge path 46 by pitching and rotating its outer peripheral pin (discharge sprocket outer peripheral pin 53P) by engaging with the feed hole SH of the carrier belt CT. The uppermost outer peripheral pin of the discharge sprocket outer peripheral pin 53P is configured to pass through the clearance opening 44K of the belt cover 44, which is located in its normal position. Figure 8A Therefore, interference between the outer peripheral pin 53P of the exhaust sprocket and the cover 44 is suppressed.

[0084] exist Figure 8BIn this configuration, the engagement height between the outer peripheral pin 53P of the discharge sprocket and the feed hole SH of the carrier belt CT is approximately the same as the engagement height between the outer peripheral pin 51P of the positioning sprocket and the feed hole SH of the carrier belt CT. However, since the outer diameter of the discharge sprocket 53 is smaller than that of the positioning sprocket 51, the rotation center of the discharge sprocket 53 (discharge sprocket rotation center 53Z) is located higher than the rotation center 51Z of the positioning sprocket 51. The discharge sprocket 53 primarily performs the function of feeding the carrier belt CT to the discharge path 46. However, after the feed hole SH at the end of the carrier belt CT disengages from the outer peripheral pin 51P of the positioning sprocket, the discharge sprocket 53 replaces the positioning sprocket 51 in positioning the concave pocket PK of the carrier belt CT at the component take-off outlet 19K.

[0085] In this way, in Embodiment 1, the transport unit 32 has a positioning sprocket 51 and a discharge sprocket 53 as sprockets that engage with the feed hole SH of the carrier CT located in a predetermined section (open section KK) covered by the belt cover 44 in the transport path 31L. The transport unit 32 is structured to transport the carrier CT by rotating the positioning sprocket 51 and the discharge sprocket 53.

[0086] exist Figure 5A , Figure 5B , Figure 6 , Figure 8A as well as Figure 8B In the first positioning pin 33, a first positioning pin 33 is fixedly disposed on the front end member 42. The first positioning pin 33 has a front end portion 33a that inserts into the first insertion hole 25, and a pin-shaped insertion portion 33b that protrudes in the opposite direction from the root of the front end portion 33a. The insertion portion 33b is pressed into and assembled into the pin assembly hole 42a formed in the front end member 42.

[0087] The central axis 33J of the front end portion 33a is parallel to the Y-axis, that is, it extends along the direction in which the belt feeder 19 is inserted (slid) into the slot 22S of the feeder assembly portion 18. As described above Figure 7B as well as Figure 7C As shown, when the main frame 41 is not provided with a front end member 42, the first positioning pin 33 is provided on the front surface of the portion 41A of the main frame 41, which is located in front of the discharge path 46.

[0088] The first positioning pin 33 is provided on the main body 31 in such a way that it can rotate around an axis (central axis 33K) that extends in the sliding direction along the main body 31 toward the feeder assembly 18 (assembly). The central axis 33K of the insertion portion 33b of the first positioning pin 33 extends parallel to the central axis 33J of the front end portion 33a. However, the central axis 33J is slightly off-center from the central axis 33K. Therefore, when the first positioning pin 33 is rotated around the central axis 33K, the front end portion 33a of the first positioning pin 33 is displaced along a circular track centered on the central axis 33K. Thus, by rotating the first positioning pin 33, the position in the X direction of the component take-out port 19K with the feeder 19 assembled in the feeder assembly 18 can be adjusted.

[0089] exist Figure 4 as well as Figure 6 In this configuration, the second positioning pin 34 is located at the end of the main frame 41, and at a position below the discharge outlet 46B of the main body 31. Figure 6 As shown, a flange 34T is provided on the lower part of the front surface of the main frame 41. A second positioning pin 34 is provided extending forward from the front surface of the flange 34T (i.e., in the direction in which the feeder 19 slides relative to the feeder assembly 18).

[0090] like Figure 8B As shown, the first locating pin 33 (specifically, the central axis 33J of the first locating pin 33) is positioned in the main body 31 at a height HT higher than the center of rotation of the sprocket that engages with the feed hole SH of the carrier belt CT in the predetermined area (open area KK) covered by the belt cover 44 in the transport path 31L. Furthermore, in the discharge path 46, the discharge path inlet 46A is located between the component take-out outlet 19K and the first locating pin 33. In the discharge path 46, the discharge path outlet 46B is located below the first locating pin 33.

[0091] exist Figure 4 In the main frame 41, a protrusion 41H is provided at the rear. The clamping member 35 is installed on the protrusion 41H. The clamping member 35 is configured to move up and down (swing) by operating the operating part 41M provided at the upper rear of the main frame 41, and to disengage from the clamping state clamped by the clamping part 28 by swinging downward.

[0092] A claw portion 35T is provided at the front end of the clamping member 35. A recess 35U is formed in the claw portion 35T for engaging with the clamping part 28. Figure 4 When the feeder 19 is assembled while sliding into the slot 22S, the claw 35T of the clamping member 35 pushes up the aforementioned clamping portion 28 provided in the feeder assembly portion 18 from below. Figure 3A as well as Figure 3BAs it slides forward, the clamping part 28 engages with the recess 35U. Thus, the clamped member 35 is fixed by the clamping part 28. The feeder 19 is fixed to the feeder assembly 18. In this way, the clamped member 35, provided on the main frame 41, is configured to be clamped by the clamping part 28 provided on the feeder assembly 18.

[0093] When the clamped member 35, which is engaged with the clamping part 28, is separated from the clamping part 28, the operating part 41M is operated. As a result, the clamped member 35 swings downward, and the claw part 35T disengages from the clamping part 28. Thus, the engagement and disengagement are configured.

[0094] Figure 10A This is a partial cross-sectional top view showing the feeder 19 and the feeder assembly 18 together in Embodiment 1 of the present invention. Figure 10B This is a partial cross-sectional side view showing the feeder 19 and the feeder assembly 18 together in Embodiment 1 of the present invention. Figure 11 This is a partial cross-sectional side view showing the feeder 19 and the feeder assembly 18 together in Embodiment 1 of the present invention. Figure 12 This is a partial cross-sectional side view showing the feeder 19 and the feeder assembly 18 together in Embodiment 1 of the present invention.

[0095] exist Figure 9 as well as Figure 11 In this configuration, connector 36 is similarly provided on protrusion 41H as clamping member 35. Connector 36 is located below clamping member 35 and is configured to connect with the aforementioned communication connector 29 provided on feeder assembly 18 when feeder 19 is mounted on feeder assembly 18. Through the electrical connection between communication connector 29 and connector 36, power can be supplied from component mounting device 1 to feeder 19, and communication or signal transmission and reception can be performed between component mounting device 1 and feeder 19.

[0096] When the belt feeder 19 with such a structure is assembled into the feeder assembly 18, the operator inserts the sliding part 41S of the belt feeder 19 into the slot 22S formed in the base part 21 of the feeder assembly 18, and slides the belt feeder 19 inward into the feeder assembly 18. Figure 9 Thus, the front end of the feeder 19 approaches the first reference member 23 and the second reference member 24 of the feeder assembly 18 from the rear. Figure 10A as well as Figure 10B Therefore, the first positioning pin 33 with feeder 19 is inserted into the first insertion hole 25 provided in the first reference member 23, and the second positioning pin 34 with feeder 19 is inserted into the second insertion hole 26 provided in the second reference member 24. Figure 11 as well as Figure 12 ).

[0097] In this way, in Embodiment 1, the first positioning pin 33 is configured to be inserted into the first positioning insertion hole 25 formed in the feeder assembly 18 as the main body 31 with the feeder 19 slides and is mounted to the feeder assembly 18. The second positioning pin 34 is configured to be inserted into the second positioning insertion hole 26 formed in the feeder assembly 18 as the main body 31 slides and is mounted to the feeder assembly 18.

[0098] Here, the second insertion hole 26 is a perfectly circular hole as described above. The inner diameter of the second insertion hole 26 is slightly larger than the diameter of the second locating pin 34. Furthermore, a tapered surface 26T is formed at the entrance of the second insertion hole 26. Figure 10B Therefore, the front end of the second locating pin 34, which approaches due to the sliding of the feeder 19, is guided into the second insertion hole 26 by the conical surface 26T, thereby entering the second insertion hole 26.

[0099] When the second locating pin 34 is inserted into the second insertion hole 26, the front surface of the flange 34T contacts the rear surface of the second reference member 24. Figure 12 Thus, the feeder 19 is positioned relative to the feeder assembly 18 in the Y direction. Furthermore, the second positioning pin 34, which enters the second insertion hole 26, is restricted from moving in the X and Z directions within the second insertion hole 26. Additionally, the first positioning pin 33, which enters the first insertion hole 25, is restricted from moving in the X direction within the first insertion hole 25. Figure 12 as well as Figure 13 Therefore, the belt feeder 19 as a whole is restricted from moving in the X, Y, and Z directions relative to the feeder assembly 18. Thus, the belt feeder 19 is fixed to the feeder assembly 18.

[0100] In addition, as mentioned above, such as Figure 8B As shown, the first positioning pin 33 is positioned on the main body 31 at a height HT higher than the height of the rotation center (rotation center 51Z of positioning sprocket 51) of the sprocket that engages with the feed hole SH of the carrier belt CT in the specified interval (open interval KK) covered by the belt cover 44 in the transport path 31L. Figure 8B Therefore, the feeder 19 is fixed relative to the feeder assembly 18 at a height close to the component take-out outlet 19K. As the position of the first positioning pin 33 approaches the height of the component take-out outlet 19K, the amplitude of the vibration in the X direction near the component take-out outlet 19K during excitation decreases. However, by setting the first positioning pin 33 at the above position, component take-out errors caused by the component mounting device 1 can be reduced, thereby ensuring a stable component supply.

[0101] In the component mounting device 1 of Embodiment 1, a first positioning pin 33 with a feeder 19 inserted into the first insertion hole 25 formed in the feeder assembly portion 18 is provided at the front end of the main body portion 31. Furthermore, the discharge passage 46 is provided downwards from a position closer to the component take-out port 19K than the front end of the main body portion 31. Therefore, the limitation on the installation range of the first positioning pin 33 based on the discharge passage 46 is eliminated. Thus, the first positioning pin 33 can be provided at the same height as the component take-out port 19K, or at a position as close as possible to the height of the component take-out port 19K.

[0102] In Embodiment 1, an example was described where a first positioning pin 33 is provided at a position higher than the height HT of the rotation center 51Z of the positioning sprocket 51, which is the lowest among a plurality of sprockets engaging with the feed hole SH of the carrier belt CT located within a predetermined range covered by the belt cover 44. However, provided there are no design constraints, the first positioning pin 33 may also be provided at a position higher than the height HD of the rotation center 53Z of the discharge sprocket 53, which is the highest. The latter allows the component supply device (belt feeder 19) to be fixed relative to the assembly (feeder assembly 18) at a height position closer to the component outlet 19K. Therefore, the amplitude near the component outlet 19K during vibration can be reduced.

[0103] (Implementation Method 2)

[0104] Next, the component mounting device in Embodiment 2 will be described. The only difference between the component mounting device in Embodiment 2 and the component mounting device 1 in Embodiment 1 is the structure of the belt cover 44 and the belt cover pressing member 45 provided in the belt feeder 19.

[0105] Figure 14A This is a side view of a portion of the feeder 19 in Embodiment 2 of the present invention. Figure 14B This is a side view of a portion of the feeder 19 in Embodiment 2 of the present invention. In Embodiment 2, as... Figure 14A as well as Figure 14B As shown, the front end of the cover (denoted as "44A") is fitted to the front end member 42 via a third axis 44AJ parallel to the X-axis. A locking portion 44H is provided at the rear end of the cover 44A, extending rearward from a downwardly extending portion 44E. Figure 14A as well as Figure 14B As shown, the covered pressing member (labeled "45A") is composed of a gripping member that extends along the Y-axis on the side of the main frame 41 and slides freely within the sliding groove 41Z.

[0106] The cover 44A can cover the open area KK from above and be pressed into the normal position by the cover pressing member 45A. Figure 14A ), and an open position in which the rear end of the cover 44A is raised upwards with the third axis 44AJ as the center ( Figure 14B The belt 44A moves between the normal position and the open position. When the belt 44A is swung from the normal position to the open position, the operator slides the belt pressing member 45A backward within the sliding groove 41Z, thereby releasing the locking part 44H of the belt 44A. In this way, even when the third axis 44AJ of the belt 44A is provided at the front end member 42, the same effect as in Embodiment 1 can be obtained.

[0107] (Implementation Method 3)

[0108] Next, the component mounting device in Embodiment 3 will be described. The component mounting device in Embodiment 3 differs from the component mounting device 1 in Embodiment 1 only in the shape of the front end member 42 of the feeder 19 and the position of the first positioning pin 33 mounted on the front end member 42.

[0109] Figure 15 This is a side view of a portion of the feeder 19 in Embodiment 3 of the present invention. In Embodiment 3, as... Figure 15 As shown, the height of the front end member 42 is higher than the upper surface of the belt cover 44, which is in its normal position. Therefore, the first locating pin 33 (specifically, the central axis 33J of the first locating pin 33) can be positioned higher than the height HT and HD of the rotation centers of all sprockets engaging with the feed hole SH of the carrier belt CT, located within a predetermined area covered by the belt cover 44. Furthermore, as... Figure 15 As shown, the first positioning pin 33 can be positioned higher than the belt cover 44. In this structure, the distance (distance in the Z direction) between the first positioning pin 33 and the second positioning pin 34 can be larger than in Embodiment 1. Therefore, the amplitude generated near the component take-off point 19K when the belt feeder 19 is subjected to an excitation force can be further reduced.

[0110] As explained above, in the component mounting device 1 of embodiments 1 to 3, a first positioning pin 33 for inserting the feeder 19 into the first insertion hole 25 formed in the feeder assembly portion 18 is provided at the front end of the main body portion 31, and the discharge passage 46 is provided downward from a position closer to the component take-out port 19K than the front end of the main body portion 31. Therefore, the first positioning pin 33 can be provided at the front end of the main body portion 31 without considering the position of the discharge passage 46. Therefore, the first positioning pin 33 can be installed at a position higher than the height HT of the rotation center of the sprocket (rotation center 51Z of the positioning sprocket 51) of the feeder 19.

[0111] Therefore, in the component mounting apparatus 1 of embodiments 1 to 3, the component supply device (belt feeder 19) can be fixed relative to the assembly part (feeder assembly part 18) at a height close to the component take-out outlet 19K. Thus, the amplitude of vibration near the component take-out outlet 19K can be suppressed when subjected to excitation force. Therefore, the belt feeder 19, which serves as a component supply device, provided in the component mounting apparatus 1 of embodiments 1 to 3, can reduce the impact of positional displacement of the component take-out outlet 19K caused by vibrations generated during the operation of the component mounting apparatus 1, thereby achieving stable component supply.

[0112] The embodiments of the present invention have now been described, but the present invention is not limited to the above description and various modifications are possible. For example, in the above embodiment, the first insertion hole 25 is a through hole that penetrates the first reference member 23 along the thickness direction (Y direction). However, the first insertion hole 25 only needs to be able to accommodate the first positioning pin 33, and it can also be located on the rear surface side of the first reference member 23. Figure 3A The second insertion hole 26 is a non-through hole that opens on the left side of the second reference member 24. Similarly, the second insertion hole 26 is a through hole that penetrates the second reference member 24 along the thickness direction (Y direction). However, the second insertion hole 26 can be a non-through hole that opens on the rear surface side of the second reference member 24, as long as it can accommodate the second positioning pin 34.

[0113] Furthermore, the component supply device (with feeder 19) shown in Embodiments 1 to 3 above has a structure in which a positioning sprocket 51 is arranged upstream of the component outlet 19K and a discharge sprocket 53 is arranged downstream of the component outlet 19K. However, the component supply device used in this invention may also have a structure in which the positioning sprocket 51 is arranged downstream of the component outlet 19K and the discharge sprocket 53 is omitted.

[0114] Industrial applicability

[0115] The present invention provides a component supply device and a component mounting device that can stably supply components by setting the positioning pin at a position close to the height of the component take-out port.
