Description

[Technical field]

[0001] The present disclosure relates to a component mounting device. [Background technology]

[0002] Conventionally, component mounting devices that mount components on a substrate are known and are used in the manufacture of various types of mounting substrates. Some of these component mounting devices require high accuracy in mounting components on a substrate, and there are examples in which components taken out from a component supply unit are temporarily placed on a temporary placement stage and recognized by a recognition camera, and then the components are picked up again and mounted on the substrate (see, for example, Patent Document 1).

[0003] An example of a component that requires high accuracy in its mounting position on a board is a light-emitting component that emits directional light, such as an LED (Light Emitting Diode). With such a light-emitting component that has directionality, if the LED is attached to a position (or in a posture) that is deviated from the target mounting position on the board, the required illuminance may not be obtained, so alignment of the component with respect to the board when mounting the component on the board is particularly important.

[0004] As described above, a conventional technique for aligning a component with respect to a board with high precision when mounting the component on the board is to provide a hole (through hole) that penetrates through the board in the thickness direction near the mounting position of the component on the board, recognize (image) the through hole from above the board with a recognition camera, and mount the component on the board using the recognized through hole as a reference.

[0005] [Patent Document 1] JP 2015-119134 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, when a specific area (e.g., an area where a through hole is located) on a board is recognized by a recognition camera from above the board, depending on the state of the board's top surface, the opening outline of the hole to be recognized may not be uniformly illuminated by the illumination from above, making it difficult to correctly recognize the shape of the hole. In addition, it is possible to provide a light source that illuminates the board over a wide area in order to align the components, but it is considered that the size of the light source must be changed each time the size of the board conveyed to the component mounting device changes. In such a case, there is a problem that the work of changing the light source increases, and the ability to flexibly accommodate boards of various sizes (models) and align the components on the board (hereinafter referred to as "model changeability") is reduced.

[0007] The present disclosure has been devised in consideration of the above-described conventional situation, and aims to provide a component mounting device that can clearly recognize, with high contrast, the positions of holes (through holes) that serve as mounting references for components to be mounted on a board, and that can perform component mounting processing for mounting components on a board with high precision while ensuring model changeability. [Means for solving the problem]

Effect of the Invention

[0011] Hereinafter, with reference to the drawings as appropriate, an embodiment specifically disclosing a component mounting device according to the present disclosure will be described in detail. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. Note that the attached drawings and the following explanation are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) First, the component mounting device according to the first embodiment will be described.

[0013] Fig. 1 is a plan view of a component mounting device 100 according to the first embodiment. The component mounting device 100 is a device that mounts components 15 such as LEDs (see Fig. 2) based on board holes 13 provided to penetrate a board 11 in the thickness direction. Note that the components 15 are not limited to LEDs. The component mounting device 100 includes a base 17, a board transport unit 19, a component supply unit 21, a head moving mechanism 23, a transfer head 25, a mounting head 27, a component camera 29, a temporary placement stage 31, support pins 33 (see Fig. 2), and reflective light-emitting pins 35 (see Fig. 2) that are light-emitting pins.

[0014] The board transport section 19 has a pair of conveyors 39 extending in the left-right direction (defined as the X-axis direction) as seen by the worker 37. The pair of conveyors 39 are disposed facing each other in the front-rear direction (defined as the Y-axis direction) as seen by the worker 37. The board transport section 19 carries in the board 11 supplied (transported) from the outside (see arrow A shown in FIG. 1) and positions it at a predetermined position. The board transport section 19 transports the board 11 by supporting a pair of parallel end edges of the board 11 from below using the pair of conveyors 39. The distance between the pair of conveyors 39 can be freely changed by a width adjustment mechanism 41 (see FIG. 2) according to the dimension of the board 11 in the width direction (Y-axis direction) to be carried in.

[0015] The component supply unit 21 is made up of a plurality of part feeders 43. Each of the plurality of part feeders 43 supplies components 15 to a component supply port 45. In the first embodiment, the part feeder 43 is, for example, a tape feeder. However, the part feeder 43 is not limited to a tape feeder.

[0016] The head moving mechanism 23 includes a fixed beam 47 extending in the Y-axis direction on a base, a front moving beam 49 extending in the X-axis direction with one end supported by the fixed beam 47, and a rear moving beam 51. The transfer head 25 is attached to the front moving beam 49, and the mounting head 27 is attached to the rear moving beam 51.

[0017] The head moving mechanism 23 moves the front moving beam 49 in the Y-axis direction relative to the fixed beam 47 and moves the mounting head 25 along the front moving beam 49, thereby moving the mounting head 25 in a horizontal plane. In addition, the head moving mechanism 23 moves the rear moving beam 51 in the Y-axis direction relative to the fixed beam 47 and moves the mounting head 27 along the rear moving beam 51, thereby moving the mounting head 27 in a horizontal plane.

[0018] The component camera 29 is provided in an area between the board transport unit 19 and the component supply unit 21 on the base. The component camera 29 has an imaging optical axis facing upward, and captures an image of the component 15 picked up by the mounting head 27 from the temporary placement stage 31 from below.

[0019] FIG. 2 is a perspective view of the main part of the board transport unit 19 shown in FIG. 1 together with the mounting head 27. For convenience of explanation, the board 11 in FIG. 2 is partially cut away. The transfer head 25 and the mounting head 27 each have a plurality of nozzles 53 extending downward. Each nozzle 53 picks up a component 15 at its lower end. In the first embodiment, as an example, the transfer head 25 and the mounting head 27 each have a configuration in which the nozzles 53 are arranged in an 8×2 (8 in the X-axis direction and 2 in the Y-axis direction) (total of 16 nozzles), but the number and arrangement of the nozzles 53 in each of the transfer head 25 and the mounting head 27 are not limited. The transfer head 25 picks up the component 15 supplied to the component supply port 45 by the part feeder 43 by using the nozzles 53 and places it on the temporary placement stage 31. The mounting head 27 picks up the component 15 placed on the temporary placement stage 31 by suction with the nozzle 53, and mounts it at a predetermined position on the board positioned by the board transport unit 19 (that is, the component mounting position).

[0020] The mounting head 27 is provided with a recognition camera 55 (FIG. 1). The recognition camera 55 has an imaging optical axis facing downward, and moves together with the mounting head 27. When the mounting head 27 picks up a component 15 temporarily placed on the temporary placement stage 31, the recognition camera 55 images the component 15 from above before the component 15 is picked up. When the mounting head 27 mounts the component 15 picked up on the board 11, the recognition camera 55 images the board hole 13 provided at the component mounting position of the component 15 from above before the component 15 is mounted on the board 11.

[0021] The component mounting device 100 has at least one light-emitting pin for irradiating light from below the board 11 to illuminate the board 11 from below when the recognition camera 55 images the board hole 13 from above, thereby enabling the recognition camera 55 to clearly image (recognize) the board hole 13.

[0022] A table 59 that can be raised and lowered by a lifting cylinder 57 is provided below the substrate transport section 19 that holds and transports the substrate 11 .

[0023] 3 is a perspective view of a table 59 on which support pins 33, reflective light-emitting pins 35, and a light source 61 are arranged. The component mounting device 100 according to the first embodiment has a light-emitting unit 63 and a support 65. The light-emitting unit 63 is arranged on the upper part of the table 59 having, for example, a rectangular shape, and locally irradiates a specific area 67 (see FIG. 4) of the board 11 carried in by the board transport unit 19 from below. One end 69 of the support 65 supports the light-emitting unit 63 from below, and the other end 71 is detachably attached to the table 59. The table 59 may have a square shape.

[0024] The light emitting unit 63 and the support 65 are integrated into a vertically long pin shape. Here, the light emitting unit 63 and the support 65 integrated into a vertically long pin shape constitute a light emitting pin. In the first embodiment, the light emitting unit 63 and the support 65 become the reflective light emitting pin 35, which is a light emitting pin.

[0025] In component mounting device 100, one or more support pins 33 for supporting the underside of substrate 11 are disposed on top of table 59. Support pin 33 has base end 73 (see FIG. 3) detachably attached to table 59. Support pin 33 stands with base end 73 attached to table 59, and supports substrate 11 from below.

[0026] In the component mounting device 100 according to the first embodiment, a plurality of holes 75 are provided in the table 59. The other end 71 of the support 65 of the reflective light-emitting pin 35 or the base end 73 of the support pin 33 is inserted into any one of these holes 75, thereby being detachably mounted on the table 59.

[0027] The component mounting device 100 further includes a light source 61 that irradiates light toward the light emitting unit 63. For example, an LED or the like can be used as the light source 61. Note that the light source 61 is not limited to an LED. The light source 61 is configured, for example, by arranging a plurality of LEDs in a straight line along one side of a pair of parallel sides (e.g., long sides) of the table 59 (see FIG. 3). These LEDs are covered by a diffusion plate.

[0028] 4 is a cross-sectional view of the substrate 11 in which the underside of a specific region 67 is illuminated by a light-emitting pin. In the reflective light-emitting pin 35, the light-emitting section 63 includes a light guide 77 (see FIG. 5) that guides light from the light source 61 (see FIG. 3) upward. In this case, the light guide 77 is formed in an inverted cone shape from, for example, a resin material. The light guide 77 receives light from the light source 61 through the conical surface and emits the light upward from a flat portion at the upper end. The flat portion has, for example, a rough surface portion on its surface, so that the light propagated through the light guide 77 is diffused and emitted.

[0029] The light guide 77 can locally guide the light from the light source 61 to the underside of a specific region 67 of the substrate 11 by making the light from the light source 61 enter the conical surface and emit it upward from the flat portion.

[0030] The specific region 67 of the substrate 11 includes a substrate hole 13 penetrating the substrate 11 in the thickness direction. The flat portion of the light-emitting portion 63 is disposed so as to face the substrate hole 13. The inside of the substrate hole 13 is brightly illuminated by illuminating the lower surface of the specific region 67 with the light-emitting portion 63. On the other hand, the upper surface of the substrate 11 is in the shadow of the light and becomes dark, and the recognition camera 55 disposed above the substrate 11 can recognize the periphery of the substrate hole 13 with higher contrast than when simply illuminating the upper surface of the substrate 11.

[0031] 5 is a perspective view of the reflective light-emitting pin 35. In the first embodiment, the light-emitting pin is a reflective light-emitting pin 35 in which the light-emitting section 63 reflects light from the light source 61 and irradiates the underside of a specific region 67 of the substrate 11. The reflective light-emitting pin 35 has a light-receiving section 79 provided on the light-emitting section 63. The light-receiving section 79 is made of, for example, a transparent resin material having an inverted cone shape. The light source 61 is placed on a table 59 arranged above the base 17 or the like. Since the conical surface of the light-receiving section 79 faces downward, it can efficiently receive light from, for example, a light source 61 arranged diagonally below the table 59.

[0032] The light receiving unit 79 has an apex portion facing downward supported by the support 65. The support 65 has a cylindrical portion 81. The cylindrical portion 81 is made of, for example, a metallic material having rigidity, and coaxially supports the light receiving unit 79. The support 65 has a base pillar portion 83 at the other end 71 of the cylindrical portion 81, the base pillar portion 83 having a larger diameter than the cylindrical portion 81. The base pillar portion 83 is made of, for example, a metallic material, and its lower surface is freely attachable to the table 59.

[0033] 6 is a cross-sectional view of the substrate 11, the underside of which is illuminated by the reflective light-emitting pin 35 in a specific region 67. The reflective light-emitting pin 35 has an engagement shaft 85 vertically attached to the underside of a base column 83. The table 59 is provided with a plurality of holes 75 at regular intervals in the planar direction (XY direction) for erecting support pins 33 for supporting the substrate 11. The reflective light-emitting pin 35 is attached to a predetermined position on the table 59 corresponding to the specific region 67 of the substrate 11 by engaging the engagement shaft 85 of the base column 83 with the hole 75.

[0034] Fig. 7 is a perspective view of a light-guiding diffusion type light-emitting pin 87. In the first embodiment, the light-emitting pin may be a light-guiding diffusion type light-emitting pin as shown in Fig. 7. The light-guiding diffusion type light-emitting pin constitutes the light-guiding diffusion type light-emitting pin 87. The light-guiding diffusion type light-emitting pin 87 guides and diffuses light from the light source 61 to illuminate the underside of a specific region 67 of the substrate 11.

[0035] The light-guiding diffusion type light-emitting pin 87 has a light-emitting portion 63 including a light distribution portion 89 made of a light guide 77 (see FIG. 8B). The light distribution portion 89 is made of, for example, a flat cylindrical transparent resin material. The light distribution portion 89 may have a diffusion plate 91 provided on the flat portion at the upper end. The light distribution portion 89 may be, for example, in the shape of an inverted cone (see FIG. 8A). The light distribution portion 89 may also include an optical element such as a concave lens (the portion indicated by the dashed line in FIG. 7) to enhance the diffusion effect of the light from the light source.

[0036] The diffusion plate 91 may be, for example, a lens diffuser (LSD: Light Shaping Diffusers). The LSD may be formed, for example, in a sheet or film shape. The LSD has a minute and random lens array and has a diffusion function that can distribute light only in the required range (light distribution angle). The diffusion plate 91 may be used in combination with any of the light-emitting units 63 of the reflection type, the light-guiding and diffusion type, and the self-luminous type.

[0037] The light distribution of the light emitting unit 63 may be achieved by using optical elements such as general concave lenses, convex lenses, etc. in addition to the diffuser plate 91 such as an LSD. Furthermore, these optical elements may be used in combination with an LSD to diffuse and shape the light.

[0038] The lower surface of the light distribution section 89 is supported by the support body 65. The support body 65 has a cylindrical light guide section 93. The light guide section 93 is made of, for example, a transparent resin material or the like, and coaxially supports the light distribution section 89. The support body 65 has a base column section 83 at the other end 71 of the light guide section 93, the base column section 83 having a larger diameter than the light guide section 93. The lower surface of the base column section 83 is freely attachable to the table 59. The light-guiding diffusion-type light-emitting pin 87 has an inverted cone-shaped light collecting section 95 made of, for example, a transparent resin material or the like, from the lower end of a fitting shaft 85 extending further from the fitting shaft 85. The light-guiding diffusion-type light-emitting pin 87 has an inverted cone-shaped light collecting section 95 made of, for example, a transparent resin material or the like. The light collecting section 95 is made of, for example, a transparent resin material or the like.

[0039] 8A and 8B are cross-sectional views of the substrate 11 in which the underside of a specific region 67 is illuminated by a light-guiding diffusion-type light-emitting pin 87. The light distribution section 89 in FIG. 8A has an inverted cone shape, and the light distribution section 89 in FIG. 8B has a cylindrical shape. In this way, the outer shape of the light distribution section 89 may be an inverted cone shape that spreads in the direction of light emission, or may be a cylindrical shape. The light-guiding diffusion-type light-emitting pin 87 is attached to a predetermined position on the table 59 corresponding to the specific region 67 of the substrate 11 by fitting the fitting shaft 85 of the base section 83 into the hole 75 of the table 59.

[0040] The light collecting portion 95 protrudes downward from the lower surface of the table 59. A base 17 and the like are disposed below the table 59. A light source 61 is disposed on the base 17. That is, in the case of the light guide diffusion type light emitting pin 87, the light source 61 is provided on the base 17 and the like below the table 59. The light guide diffusion type light emitting pin 87 receives light from the light source 61 at the light collecting portion 95 protruding from the lower surface of the table 59, and propagates the taken-in light to the light distribution portion 89 by the light guide portion 93. The light guided from the light guide portion 93 to the light distribution portion 89 is emitted upward from the flat portion of the light distribution portion 89. The light guide diffusion type light emitting pin 87 has a diffusion plate 91 such as the above-mentioned LSD provided on the flat portion of the light distribution portion 89.

[0041] Fig. 9 is a perspective view of a self-luminous light-emitting pin 97. In the first embodiment, the light-emitting pin may be a self-luminous type light-emitting pin as shown in Fig. 9. A self-luminous type light-emitting pin is called a self-luminous light-emitting pin 97. In the self-luminous light-emitting pin 97, the light-emitting unit 63 has a self-luminous light source 99. The self-luminous light-emitting pin 97 diffuses light from the self-luminous light source 99 to illuminate the underside of a specific region 67 of the substrate 11.

[0042] The light emitting unit 63 is made of a transparent resin material or the like and has a flat cylindrical shape containing a self-emitting light source 99. The light emitting unit 63 may be provided with a diffusion plate 91 such as an LSD on the flat portion at the upper end. The light emitting unit 63 may be in an inverted cone shape (see FIG. 10).

[0043] The lower surface of the light-emitting unit 63 is supported by the support 65. The support 65 has a cylindrical portion 81. The cylindrical portion 81 is made of, for example, a metal material or the like, and coaxially supports the light-emitting unit 63. The support 65 has a base pillar portion 83 at the other end 71 of the cylindrical portion 81, the base pillar portion 83 having a larger diameter than the cylindrical portion 81. The base pillar portion 83 is made of, for example, a metal material or the like, and the lower surface is freely attachable to the table 59.

[0044] The self-light-emitting pin 97 has a fitting shaft 85 vertically attached to the underside of the base column 83. The self-light-emitting pin 97 is disposed at a predetermined position on the table 59 corresponding to a specific region 67 of the substrate 11 by fitting the fitting shaft 85 of the base column 83 into the hole 75 of the table 59.

[0045] 10A and 10B are cross-sectional views of the substrate 11 in which the underside of a specific region 67 is illuminated by a self-luminous light-emitting pin 97. The light distribution section in FIG. 10A has an inverted cone shape similar to the light distribution section 89 in FIG. 8A, and the light distribution section in FIG. 10B has a cylindrical shape similar to the light distribution section 89 in FIG. 8B. In this way, the outer shape of the light distribution section may be an inverted cone shape expanding in the light emission direction, or may be a cylindrical shape. When power is supplied to the terminal section 101 and the self-luminous light source 99 is driven, the self-luminous light-emitting pin 97 emits light upward from the flat section at the upper end. The self-luminous light-emitting pin 97 is provided with a diffusion plate 91 such as the above-mentioned LSD on the flat section of the light-emitting section 63. This allows the self-luminous light-emitting pin 97 to locally illuminate the light emitted by the self-luminous light source 99 from below onto the specific region 67 of the substrate 11.

[0046] The self-luminous light-emitting pin 97 is provided at the lower end of the fitting shaft 85 with positive and negative terminal portions 101 exposed on the lower surface of the table 59. The terminal portions 101 are conductively connected to the self-luminous light source 99 via insulated wiring or the like inserted into the inside of the cylindrical portion 81. When power for illumination is supplied from the device to the terminal portions 101 exposed on the lower surface of the table 59, the self-luminous light-emitting pin 97 emits light from the self-luminous light source 99. More specifically, the self-luminous light-emitting pin 97 has, for example, a positive power source (+) connected to the outer periphery of the fitting shaft 85 via the hole 75 of the table 59, and a negative power source (-) connected to the lower end surface of the fitting shaft 85 via a terminal 103.

[0047] Next, the operation of the component mounting device 100 according to the first embodiment will be described.

[0048] When the component mounting device 100 mounts the components 15 on the board 11 positioned by the board transport unit 19, the transfer head 25 first operates to pick up the components 15 supplied to the respective component supply ports 45 by the part feeders 43 constituting the component supply unit 21. Here, the transfer head 25 has, for example, 16 nozzles 53, and picks up the 16 components 15 by suction with each nozzle 53.

[0049] After picking up the 16 components 15 with the 16 nozzles 53 , the transfer head 25 moves to above the temporary placement stage 31 and places the picked-up 16 components 15 on the temporary placement stage 31 .

[0050] In the component mounting device 100, after the component 15 is placed on the component placement section of the temporary placement stage 31 by the transfer head 25, the mounting head 27 moves above the temporary placement stage 31, and the recognition camera 55 provided on the mounting head 27 images (recognizes) each component 15 from above.

[0051] Once the recognition camera 55 has finished recognizing the components 15 on the temporary placement stage 31, the mounting head 27 uses the multiple (16) nozzles 53 to suction and pick up the multiple (16) components 15 placed on the temporary placement stage 31.

[0052] After picking up the multiple components 15 by the multiple nozzles 53, the mounting head 27 moves above the component camera 29 and causes the component camera 29 to capture an image of each of the 16 picked up components 15. After each component 15 is captured and recognized by the component camera 29, the mounting head 27 moves above the board transport section 19. Then, the light source 61 provided on the table 59 below the board 11 is turned on, and the light from the light source 61 is irradiated from below to a specific area 67 of the board 11 by the reflective light emitting pin 35. As a result, the outline shape of each board hole 13 provided in the board 11 is brightly illuminated. On the other hand, the upper surface of the board 11 is dark because it is in the shadow of the light. As a result, the recognition camera 55 can recognize the periphery of each board hole 13 with high contrast.

[0053] Next, the operation of the component mounting device 100 according to the first embodiment will be described.

[0054] The component mounting device 100 of embodiment 1 comprises a substrate transport unit 19 that holds and transports the substrate 11, a table 59 arranged below the substrate transport unit 19, a light-emitting unit 63 arranged above the table 59 and that locally illuminates from below a specific area 67 of the substrate 11 brought in by the substrate transport unit 19, and a support body 65 having one end 69 that supports the light-emitting unit 63 from below and the other end 71 that is removably attached to the table 59.

[0055] In the component mounting device 100 according to the first embodiment, a light emitting unit 63 is disposed on a table 59 disposed below the board transport unit 19. The light emitting unit 63 may be a unit that reflects light, such as a mirror. The light emitting unit 63 may be a unit that transmits light or a unit that diffuses light while transmitting it. The light emitting unit 63 may also be a unit that emits light itself. Here, reflection includes regular reflection (specular reflection) by a mirror and diffuse reflection (diffuse reflection) by a diffusion plate.

[0056] The light emitting unit 63 is supported from below by one end 69 of the support 65. The other end 71 of the support 65, which is opposite to the one end 69, is detachably attached to the table 59. That is, the light emitting unit 63 is detachably attached to the upper part of the table 59 via the other end 71 of the support 65. The light emitting unit 63 locally irradiates a specific area 67 of the board 11 carried in by the board transport unit 19 from below. This allows the component mounting device 100 to clearly recognize the specific area 67 of the board 11 with high contrast, and allows the component mounting operation of mounting the components 15 on the board 11 based on the specific area 67 to be performed with high accuracy.

[0057] The light-emitting unit 63 does not need to change the light source size each time the board size changes, in each of the cases where the light-emitting unit 63 reflects light from the light source 61, where the light-emitting unit 63 guides and diffuses light from the light source 61, and where the light-emitting unit 63 has a self-emitting light source 99. In other words, the light-emitting unit 63 does not reduce the model changeability in any case.

[0058] One end 69 of the support 65 supports the light-emitting unit 63 from below, and the other end 71 opposite the one end 69 is attached to the table 59. In other words, the light-emitting unit 63 is disposed at the upper end portion of the vertically long support 65. The light-emitting unit 63 can be disposed upright from the table 59 with an area that is sufficiently small compared to the area of ​​the substrate 11. The light-emitting unit 63 can be disposed at each position on the table 59 according to a specific region 67 on the substrate 11. For this reason, the light-emitting unit 63 can be disposed on the table 59 with a minimum necessary mounting area, for example, when transporting a small substrate.

[0059] In the component mounting device 100, the light emitting section 63 includes a light guide 77 that guides the light from the light source 61 upward.

[0060] In this component mounting device 100, the light emitting section 63 is configured to include a light guide 77. The light guide 77 is formed, for example, in an inverted cone shape, and guides the light from the light source 61 upward by reflection or diffusion. Of course, the light guide 77 may be a rod-shaped or linear medium (waveguide) made of a transparent material having a substantially uniform cross section and confining and propagating light. In this case, the light guide 77 may be an optical fiber having a core-clad structure. Furthermore, the light guide 77 may have a diffusion plate 91 that diffuses light in addition to the waveguide. That is, a configuration in which the diffusion plate 91 is provided at the light emitting end of the waveguide may be used.

[0061] For example, a lens diffuser can be suitably used as the diffuser 91. This allows the diffuser 91 to diffuse and shape the light, eliminate uneven illumination, and provide efficient illumination. As a result, the light emitting unit 63 can efficiently guide the light from the light source 61 upward in any direction using the light guide 77.

[0062] The light distribution of the light emitting unit 63 may be achieved by using optical elements such as general concave lenses, convex lenses, etc. in addition to the diffuser plate 91 such as an LSD. Furthermore, these optical elements may be used in combination with an LSD to diffuse and shape the light.

[0063] In the component mounting apparatus 100 , the light guide 77 guides the light from the light source 61 to the lower surface of the specific region 67 of the substrate 11 .

[0064] In this component mounting device 100, the light guide 77 guides the light from the light source 61 upward by reflection and diffusion, and efficiently irradiates the underside of a specific region 67 of the substrate 11 arranged above. This allows the light emitting unit 63 to locally and efficiently irradiate the specific region 67 of the substrate 11 from below, compared to irradiating the entire underside of the substrate 11.

[0065] Moreover, in the component mounting device 100 , the specific region 67 includes the board hole 13 penetrating the board 11 in the thickness direction, and the light emitting portion 63 is disposed so as to face the board hole 13 .

[0066] In this component mounting device 100, the target onto which light is irradiated by the light-emitting unit 63 is the board hole 13 that penetrates the board 11 in the thickness direction. The light-emitting unit 63 is disposed opposite the board hole 13, so that light can be irradiated locally and efficiently into the board hole 13. The light from the light-emitting unit 63 is irradiated locally, so that the inside of the board hole 13 is brightly illuminated. Meanwhile, the surface of the board 11 opposite the light-emitting unit 63 becomes dark because it is in the shadow of the light that has passed through the board hole 13. This allows the periphery of the board hole 13 on the board 11 to be recognized with high contrast.

[0067] In component mounting device 100, board transport section 19 transports board 11 by using a pair of conveyors 39 to support a pair of parallel opposite end edges of board 11 from below.

[0068] In this component mounting device 100, a pair of conveyors 39 supports a pair of parallel end edges of the board 11 from below and transports the board. For example, the distance between the pair of parallel end edges of the board 11 is defined as the width direction. The width adjustment mechanism 41 allows the pair of conveyors 39 to freely change the widthwise distance of the board 11 in accordance with the dimension of the board 11 in the width direction (Y-axis direction) to be carried in. Therefore, even if the size of the board 11 changes, the board transport unit 19 can automatically support and transport the board 11 of the new size by changing the distance between the pair of conveyors 39 using the width adjustment mechanism 41.

[0069] In the component mounting device 100, the light emitting portion 63 and the support body 65 are integrated into one body having a pin shape aligned in a direction perpendicular to the surface direction of the substrate 11.

[0070] In this component mounting device 100, the light emitting portion 63 and the support 65 are integrated into a vertically long pin shape. Here, the light emitting portion 63 and the support 65 integrated into a vertically long pin shape constitute a light emitting pin. The light emitting pin stands up when the support 65 is attached to the table 59. The light emitting portion 63 is disposed at the upper end of the standing light emitting pin. In other words, the light emitting pin stands up when the support 65 is attached to the table 59, and the light emitting portion 63 at the upper end locally irradiates a specific area 67 of the substrate 11 from below.

[0071] The position and number of the light-emitting pins can be freely changed according to the position and number of the board holes 13. As a result, the component mounting device 100 is provided with light-emitting pins, which greatly improves the model changeability. That is, the light-emitting pins can be freely arranged according to the board holes 13 of the switched board 11. If the number of board holes 13 is small, it is sufficient to install the minimum number of light-emitting pins required. Furthermore, the light-emitting pins can be automatically arranged at a predetermined position on the table by the mounting head 27, etc., which is a basic functional unit provided in the component mounting device 100. As a result, the component mounting device 100 can reduce the burden on the operator 37 of changing the lighting position when switching models. It can also contribute to the automation of equipment.

[0072] Furthermore, since the light emitting pins are arranged only in the specific region 67 of the substrate 11, for example, when a large light source capable of irradiating the entire surface of the substrate 11 is installed, heat build-up caused by the large light source can be suppressed.

[0073] Moreover, the component mounting device 100 further includes a light source 61 that irradiates (an example of a supply of) light toward the light emitting section 63.

[0074] In this component mounting device 100, a light emitting unit 63 receives light from a separately provided light source 61 and locally irradiates a specific region 67 of the board 11. Therefore, the light emitting pin irradiates the specific region 67 of the board 11 by reflecting or guiding the light from the light source 61. The light reflected or guided by this is further diffused and shaped by a diffusion plate 91 or the like before being irradiated.

[0075] In the component mounting device 100 , the light emitting portion 63 is a light emitting pin of a reflection type that reflects light from the light source 61 and irradiates the lower surface of a specific region 67 of the board 11 .

[0076] In this component mounting device 100, the light-emitting pin may be a reflective light-emitting pin 35. The reflective light-emitting pin 35 has a light-receiving portion 79 provided on a light-emitting portion 63. The light-receiving portion 79 is made of a transparent resin material or the like and has an inverted cone shape. Since the conical surface of the light-receiving portion 79 faces downward, it can efficiently receive light from a light source 61 installed on the table 59, for example.

[0077] When light from the light source 61 is incident on the conical surface of the light-receiving portion 79, the reflective light-emitting pin 35 emits light from the flat portion at the upper end. The reflective light-emitting pin 35 is provided with a diffusion portion such as a diffusion plate 91 on the flat portion of the light-receiving portion 79. This allows the reflective light-emitting pin 35 to locally irradiate the light received by the light-receiving portion 79 to a specific region 67 of the substrate 11 from below.

[0078] In the component mounting device 100 , the light emitting section 63 is a light guiding and diffusing type light emitting pin that guides and diffuses the light from the light source 61 to illuminate the underside of a specific region 67 of the board 11 .

[0079] In this component mounting device 100, the light-emitting pin may be a light-guiding and diffusing type light-emitting pin 87. The light-guiding and diffusing type light-emitting pin 87 has a light distribution section 89 provided on the light-emitting section 63. The light distribution section 89 has a diffusion plate 91 such as an LSD provided on a flat portion at the upper end.

[0080] The light-guiding diffusion type light-emitting pin 87 has an engagement shaft 85 with a light-guiding portion 93 extending therefrom suspended from the lower surface of a base portion 83. The light-guiding diffusion type light-emitting pin 87 is disposed at a predetermined position on the table 59 corresponding to a specific region 67 of the substrate 11 by engaging the engagement shaft 85 of the base portion 83 with a hole 75 in the table 59.

[0081] The light-guiding diffusion type light-emitting pin 87 has a light-collecting portion 95 that protrudes downward from the lower surface of the table 59. A base 17 and the like are disposed below the table 59. A light source 61 is mounted on the base 17. The light-guiding diffusion type light-emitting pin 87 receives light from the light source 61 at the light-collecting portion 95 that protrudes from the lower surface of the table 59, and propagates the taken-in light to the light distribution portion 89 via the light-guiding portion 93. The light-guiding diffusion type light-emitting pin 87 has a diffusion plate 91 such as the above-mentioned LSD provided on the flat portion of the light distribution portion 89. This allows the light-guiding diffusion type light-emitting pin 87 to locally irradiate the light emitted from the light distribution portion 89 to a specific region 67 of the substrate 11 from below.

[0082] Furthermore, the light source 61 can be installed under the table 59 on which the light emitting pins are attached. When the light source 61 is installed on the table 59, the component mounting device 100 requires a process of attaching and detaching a connector between the table 59 and the light source 61 when the table is attached or detached. In contrast, if the light source 61 is installed on the base 17 or the like below the table 59, the process of attaching and detaching the connector when the table is attached or detached is not required. This further improves the model changeability of the component mounting device 100.

[0083] In the component mounting device 100 , the light emitting section 63 is a self-emitting type light emitting pin that has a self-emitting light source 99 and diffuses light from the self-emitting light source 99 to illuminate the underside of a specific region 67 of the board 11 .

[0084] In this component mounting device 100, the light emitting pin may be a self-light emitting pin 97. The self-light emitting pin 97 has a self-light emitting light source 99 such as an LED provided in a light emitting section 63. The light emitting section 63 is made of a transparent resin material or the like that contains the self-light emitting light source 99. The light emitting section 63 may have a diffusion plate 91 such as an LSD provided on a flat section at the upper end.

[0085] The self-luminous light-emitting pin 97 has positive and negative terminal portions 101 exposed on the underside of the table 59 provided at the lower end of the fitting shaft 85. The terminal portions 101 are conductively connected to the self-luminous light source 99 via insulating wiring or the like. When power for illumination is supplied from the device to the terminal portions 101 exposed on the underside of the table 59, the self-luminous light source 99 of the self-luminous light-emitting pin 97 emits light.

[0086] In addition, the component mounting device 100 has one or more support pins 33 arranged on the upper part of the table 59 to support the underside of the substrate 11, and the light-emitting unit 63 is a self-luminous type light-emitting pin that has a self-luminous light source 99 and diffuses light from the self-luminous light source 99 to illuminate the underside of a specific area 67 of the substrate 11.

[0087] In this component mounting device 100, the reflective light-emitting pins 35, the light-guiding diffusion light-emitting pins 87, and the self-luminous light-emitting pins 97 are compact light-emitting pins that are vertically long and stand upright on the table 59. This allows the installation range of the support pins 33 to be significantly expanded compared to the case where a planar lighting unit that illuminates the entire board is installed.

[0088] Furthermore, in the component mounting device 100, a plurality of holes 75 are provided in the table 59, and the other end 71 of the support body 65 or the base end 73 of the support pin 33 is inserted into any one of the holes 75.

[0089] In this component mounting device 100, the other end 71 of the support 65 and the base end 73 of the support pin 33 are inserted into one of a plurality of holes 75 provided in the table 59. More specifically, the other end 71 of the support 65 is provided with a base column portion 83, and a fitting shaft 85 hangs down from the base column portion 83. The support 65 is mounted on the table 59 by inserting the fitting shaft 85 into the hole 75. The support pin 33 also has a fitting shaft 85 at its lower end, and is mounted on the table 59 by inserting the fitting shaft 85 into the hole 75. The light-emitting pin and the support pin 33 having the support 65 are sucked by the nozzle 53 provided in the mounting head 27, and can be automatically arranged in the hole 75 of the table 59 corresponding to the specific area 67 of the board 11. As a result, the component mounting device 100 can reduce the burden of the operator 37 in changing the lighting position when changing the model. It can also contribute to the automation of equipment.

[0090] (Embodiment 2) Next, a component mounting device according to a second embodiment will be described.

[0091] 11 is a cross-sectional view of a substrate 11 in which the underside of a specific region 67 is illuminated by a reflective light-emitting pin 105 in a component mounting device 200 according to embodiment 2. Note that in embodiment 2, the same members and parts as those described in embodiment 1 with reference to Figs. 1 to 10 are denoted by the same reference numerals, and overlapping descriptions are simplified or omitted, and different contents are described.

[0092] In component mounting device 200 according to the second embodiment, light sources 61 are disposed on each of a pair of conveyors 39 constituting board transport section 19. That is, light sources 61 are disposed along each of a pair of parallel sides of table 107 (for example, along the long sides when table 107 has a rectangular shape) (see FIGS. 13 and 20).

[0093] The light source 61 is configured by, for example, arranging a plurality of LEDs in a line along the above-mentioned side of the table 107. These LEDs are covered with a diffusion plate 91. The light quantity and light distribution of the light source 61 are optimally corrected by passing light from the linearly arranged plurality of LEDs through the diffusion plate 91. As a result, the light source 61 arranged on the opposing surfaces of the pair of conveyors 39 directs the emitted light toward each opposing surface in a direction parallel to the table 107.

[0094] In the component mounting device 200, the table 107 is formed of, for example, a magnetic material. A reflective light-emitting pin 105, which is a light-emitting pin, is attached to the table 107. The other end 71 of the support 65 of the reflective light-emitting pin 105 is fixed to an arbitrary position on the table 107 by a magnet 109. Similarly, the base end 73 of the support pin 111 is fixed to an arbitrary position on the table 107 by a magnet 109. Note that the component mounting device 200 may not use a magnetic material for the table 107, and a light-emitting pin or the like may be attached by fitting the fitting shaft 85 into the hole 75 as in the first embodiment.

[0095] FIG. 12 is a perspective view of the reflective light-emitting pin 105 shown in FIG. 11. The reflective light-emitting pin 105 has a reflecting section 113 formed, for example, in a cylindrical shape, and its lower surface is supported by a support 65. The reflecting section 113 has a rectangular mirror 115 that reflects horizontal light upward at an angle of 45° from the z-axis direction toward the x-axis direction or the y-axis direction. The mirror 115 can be mounted with an angle corrected so as to maximize reflection efficiency. Since the mirror 115 of the reflecting section 113 is inclined at an angle of approximately 45°, the mirror 115 can efficiently receive light from the side by the light source 61 provided on the conveyor 39 and locally irradiate a specific region 67 of the substrate 11 from below.

[0096] The support 65 has a cylindrical portion 81 having a smaller diameter than the reflecting portion 113. The cylindrical portion 81 is made of a metal material or the like, and coaxially supports the reflecting portion 113. The support 65 has a base column portion 83 having a larger diameter than the cylindrical portion 81 at the other end 71 of the cylindrical portion 81. The base column portion 83 is made of a metal material or the like, and supports the cylindrical portion 81 so as to be freely rotatable. This allows the reflecting portion 113 to orient the light capture direction of the mirror 115 in any direction within 360°. The base column portion 83 contains a magnet 109 inside, so that the lower surface can be freely attached to the table 59. It is preferable that the base column portion 83 is provided with an adhesive force release mechanism that can release the adhesive force of the magnet 109 when changing the position.

[0097] 13 is a plan view of the reflective light-emitting pin 105 and support pin 111 arranged on the table 107. In the component mounting device 200, the reflective light-emitting pin 105 is attached to the upper surface of the table 107 located below the substrate 11 such that the reflecting portion 113 is arranged directly below the substrate hole 13. The reflective light-emitting pin 105 having the reflecting portion 113 reflects light emitted horizontally upward. The reflective light-emitting pin 105 can be attached and detached to any location on the table 107 by fixing the base portion 83 with a magnet 109.

[0098] In the component mounting device 200, the reflective light-emitting pin 105 is sucked and held by the nozzle 53 of the mounting head 27, and placed at a predetermined coordinate on the table 107. At that time, the angle is corrected so that the light emitted from the nearest light source 61 is perpendicular to the mirror 115. If an obstacle such as a support pin 111 is present between the reflective light-emitting pin 105 and the nearest light source 61, the light receiving direction of the reflecting section 113 is adjusted so that another light source 61 is selected.

[0099] 14 is a perspective view of the reflective light-emitting pin 117. In the component mounting device 200, the light-emitting pin may be the reflective light-emitting pin 117 having a light-emitting portion 63 similar to the reflective light-emitting pin 35 shown in the first embodiment. The reflective light-emitting pin 117, which is an example of a reflector, has a light-receiving portion 79 made of a transparent resin material or the like having an inverted cone shape. Since the conical surface of the light-receiving portion 79 faces downward, it can efficiently receive light from the light source 61 installed in the horizontal direction on the conveyor 39, for example.

[0100] 15 is a perspective view of a reflective light-emitting pin 119 according to a modified example. In the component mounting device 200, the light-emitting pin may be a reflective light-emitting pin 119 having a conical mirror 121. The conical mirror 121 has a conical surface that serves as a mirror surface. In addition, the reflective light-emitting pin 119 has a circular diffusion plate 91 coaxially fixed to the top of the conical mirror 121. Since the light-receiving unit 79 of the reflective light-emitting pin 119 has the conical mirror 121, the light-receiving unit 79 receives light from a light source 61 installed in the lateral direction on the conveyor 39, for example, and reflects the light upward. At this time, the reflected light passes through the diffusion plate 91, so that the light amount and light distribution are optimally corrected.

[0101] 16 is a side view of the reflective light-emitting pin 117 and the reflective pin 123 arranged on the table 107. The component mounting device 200 can be equipped with the reflective pin 123 arranged on the upper part of the table 107. The reflective pin 123 is configured to have a reflector 125 that reflects light from the light source 61 to a light-emitting part 63 such as the reflective light-emitting pin 117, and a support body 65 having one end 69 that supports the reflector 125 from below and the other end 71 that is detachably attached to the table 107.

[0102] 17 is a perspective view of the reflecting pin 123. The reflecting pin 123 can be a polyhedron with multiple faces serving as mirrors 115 to form a reflector 125. The polyhedron can be a polyhedron mirror 127 having multiple square mirrors with adjacent generatrix lines among multiple equally spaced generatrix lines as two sides on the outer circumferential surface of a cylinder.

[0103] 18 is a perspective view of a modified reflecting pin 129. The reflecting pin 129 may be provided with a reflector 125 and a cylindrical reflecting surface 131 having a mirror 115 on the outer circumferential surface of the cylinder.

[0104] Fig. 19 is a perspective view of the reflective light-emitting pin 119, the reflective pin 123, and the reflective pin 129 arranged on the table 107. The component mounting device 200 can use, for example, the reflective light-emitting pin 117 having an inverted cone-shaped light-receiving portion 79, the reflective pin 123, the reflective pin 129, and the like in combination. Note that the combination of the light-emitting pin and the reflective pin shown in Fig. 19 is one example, and the reflective light-emitting pin 105, the reflective light-emitting pin 117, the reflective light-emitting pin 119, the reflective pin 123, and the reflective pin 129 may be used in any combination.

[0105] 20 is a plan view of the reflective light-emitting pin 117 and the reflective pin 123 arranged on the table 107. In the component mounting device 200, by mounting the reflective light-emitting pin 117 on the table 107, the light from the light source 61 is locally irradiated onto the underside of a specific region 67 of the board 11 by the light-emitting portion 63 of the reflective light-emitting pin 117. In addition, by arranging the reflective pin 123 at an optimal location in consideration of the positions of the reflective light-emitting pin 117 and the light source 61, the amount of light incident on the reflective light-emitting pin 117 can be increased. As a result, the reflective light-emitting pin 117 can irradiate the specific region 67 with stronger light intensity.

[0106] Furthermore, when the reflective light-emitting pin 117 is installed, the component mounting device 200 can mount the light-emitting unit 63 without correcting the rotation angle around the Z axis. In other words, since the light-emitting unit 63 has an inverted cone shape, it can receive light from the light source 61 from 360° directions. Furthermore, the reflective light-emitting pin 117 and the reflective pin 123 can be automatically positioned by equipment, reducing the burden on the worker 37.

[0107] Next, the operation of the component mounting device 200 according to the second embodiment will be described.

[0108] In the component mounting apparatus 200 , the light source 61 is disposed in the board transport section 19 which includes a pair of conveyors 39 .

[0109] In this component mounting device 200, the light source 61 is disposed on the opposing surface of the board transport section 19 that is provided with the pair of conveyors 39. The reflective light emitting pin 35 receives light from the light source 61 disposed on the board transport section 19 and enters the light receiving section 79 from the side. In this component mounting device 200, the light source 61 is not disposed on the table 107, so there is no need to increase or decrease the light source 61 when changing the width of the board 11 (in other words, when switching to a board having a different width (size)). In addition, when switching the model, the light source 61 moves with the width adjustment operation of the conveyor 39, so there is no need to attach or remove the light source 61, improving model switchability. Furthermore, since the light source 61 is not disposed on the table 107, there is no limit to the range in which the support pin 111 and the light emitting pin can be installed. In other words, the light source 61 does not get in the way of installing the support pin 111 and the light emitting pin.

[0110] In addition, the component mounting device 200 further includes a reflective pin 123 that is arranged on the upper part of the table 107 and includes a reflector 125 that reflects light from the light source 61 to the light emitting part 63, and a support 65 whose one end 69 supports the reflector 125 from below and whose other end 71 is removably attached to the table 107.

[0111] In this component mounting device 200, a reflective pin 123 dedicated to reflection is provided on the top of the table 107 in a positionable manner. The reflective pin 123 has a reflector 125 that reflects light from the light source 61 to the light emitting portion 63 of the reflective light emitting pin 35. The reflector 125 is supported from below by one end 69 of the support body 65. The other end 71 of the support body 65 is detachably attached to the table 107. The reflective pin 123 can be positioned on the top of the table 107 in the same manner as the light emitting pin.

[0112] The reflective pin 123 is positioned so that light is evenly irradiated onto the cone-shaped light receiving portion 79 of the reflective light-emitting pin 35. This allows the reflective pin 123 to correct the light quantity and light distribution of the reflective light-emitting pin 35. The reflective pin 123 is automatically positioned at the optimal position, taking into account the reflective light-emitting pin 35 and the light source positions.

[0113] In addition, in component mounting device 200 , table 107 is made of a magnetic material, and the other end 71 of support 65 or base end 73 of support pin 111 is fixed to any position on table 107 by magnet 109 .

[0114] In this component mounting device 200, the other end 71 of the support 65 and the base end 73 of the support pin 111 are attached to the table 107 by magnets 109. When a plurality of holes 75 are formed vertically and horizontally in the table 107, the fixing positions of the light emitting pins and support pins 111 having the other end 71 are restricted by the arrangement positions of the holes 75. In contrast, the light emitting pins and support pins 111 having magnets 109 in the support 65 and base end 73 can be arranged in any optimal position on the substrate 11 where support is required, without being restricted by the arrangement positions of the holes 75.

[0115] The light-emitting pins having magnets 109 on the support 65 and the support pins 111 having magnets 109 on their base ends 73 are attracted by the nozzles 53 provided on the mounting head 27, and can be automatically arranged in the holes 75 in the table 107 corresponding to the specific regions 67 of the substrate 11. It is preferable that the light-emitting pins and the support pins 111 are provided with an attraction force release mechanism that can release the attraction force of the magnets 109 when changing the arrangement. This allows the component mounting device 200 to reduce the burden on the operator 37 of changing the lighting position when changing the model. It can also contribute to the automation of equipment.

[0116] Therefore, according to the component mounting apparatus 100, 200 of this embodiment, a specific area 67 (i.e., the component mounting position) provided on the board 11 can be clearly recognized with high contrast, and the component mounting operation of mounting the component 15 on the board 11 can be performed with high precision while ensuring model changeability.

[0117] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications, corrections, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present disclosure. In addition, the components in the various embodiments described above may be arbitrarily combined within the scope of the invention. [Industrial Applicability]
