Description

TECHNICAL FIELD

[0001] The present application relates to a component taking-out method and device thereof, a component placing method and device thereof, and a manufacturing method and device of an electronic component, which are suitable for a component taken out from a manufacturing device or the like. BACKGROUND

[0002] As a device which transports an electronic component from a supply source such as a manufacturing device or a carrying-in device to a supply destination such as a manufacturing device or a packaging device of a next process, there is a device described in Patent Literature 1. In the device of Patent Literature 1, an air core coil wound around a shaft member is gripped by two holders and pulled out from the shaft member to be transported onto a substrate, and the air core coil is pushed out by a pushing member and inserted into a prescribed position of the substrate at the transportation destination.

[0003] Further, as a device related to placement of a transported electronic component, there is a device described in Patent Literature 2. In the device described in Patent Literature 2, flatness of a component placed on a substrate is checked, and in a case where the component is floated from the substrate or the like, the component is pressed to correct a mounting state. Particularly when an electronic component is miniaturized, generally the mechanical strength of the electronic component becomes weak, and it is difficult to handle.

[0005] PATENT LITERATURE

[0006] Patent Literature 1: Japanese Patent Application Laid-Open No. 9-320873

[0007] Patent Literature 2: Japanese Patent Application Laid-Open No. 2007-067343 SUMMARY

[0008] However, in the method of mechanically holding a component or pressing a component as disclosed in Patent Literature 1, in a case where a force necessary or more is applied to the component or positioning accuracy is reduced, there is a risk of damaging the component. Particularly when the component is miniaturized (for example, a surface mounting type electronic component of a substantially cuboid shape having an outer dimension of 0.6 mm x 0.6 mm x 0.3 mm or less), the strength becomes low, and sometimes the component is damaged due to a slight overload. Further, when the component is miniaturized, it can not be possible to hold the component due to a slight error of a working position of holding the component, or the component can be dropped and damaged due to contact with an inappropriate portion of the component, and the like.

[0009] Further, in a case where the mounting state is corrected by mechanically pressing the component as disclosed in Patent Literature 2, there are technical problems such as application of a force necessary or more to the component to damage the component, or damage of a surface of the component due to mechanical contact, and improvement is required.

[0010] An aspect of the present application provides a component taking-out method, a component taking-out device, and an electronic component manufacturing method and device, which do not damage or drop the component and allow the component to be properly taken out from a device or a component supply source.

[0011] In addition, an aspect of the present application provides a component placing method and device, and an electronic component manufacturing method and device, which do not damage the component and allow the component to be properly placed in a predetermined posture, thereby efficiently manufacturing an electronic component.

[0012] A component taking-out method according to an embodiment of the present application is a method of taking out a component disposed around a rod-shaped member having one end side open, and includes:

[0013] a step of adsorbing the component disposed around the rod-shaped member with an adsorption portion;

[0014] a step of causing a contact member to contact the component from the other end side of the rod-shaped member and move the contact member toward the one end side of the rod-shaped member, thereby causing the component to be detached from the rod-shaped member.

[0015] In the component taking-out method according to the present application, the component is adsorbed with the adsorption portion and is caused to be detached from the rod-shaped member by the contact member contacting the component, so that mechanical load on the component can be reduced and damage to the component can be prevented, as compared with the case where the component is held and taken out by a holder or the like. In addition, even if the adsorption force is weak, dropping of the component or the like can be prevented, as compared with the case where the component is adsorbed only with the adsorption portion. As a result, according to the component taking-out method according to the present application, the component disposed around the rod-shaped member can be properly taken out without being damaged or dropped, and the like, in a supply source such as a manufacturing device or a carrying-in device. In particular, the present application is preferably used in a small electronic component, and is suitable for a surface-mount electronic component having an outer dimension of 0.6 mm x 0.6 mm x 0.3 mm or less, which is substantially cuboid.

[0016] A pair of columnar portions that can be opened and closed in a direction perpendicular to the axial direction of the rod-shaped member and can move in the axial direction of the rod-shaped member, i.e., the pair of columnar portions each of which is formed with a protrusion portion protruding in a direction in which the pair of columnar portions are opened and closed, can be used as the contact member, an end surface of the protrusion portion directed toward the one end side of the rod-shaped member can be caused to contact the electronic component as a contact surface, and the pair of columnar portions can be caused to move toward the one end side of the rod-shaped member, thereby causing the component to be detached.

[0017] The contact surface of the pair of columnar portions can be caused to contact a peripheral edge of the other end side of the component. In addition, a component constituting a part of the pair of columnar portions can be disposed opposite to the peripheral surface with a predetermined gap.

[0018] In this method, the pair of columnar portions as the contact members movably engage or support the member only by bringing the contact surfaces into contact with the peripheral edge of the other end side of the member. Therefore, the columnar portions are prevented from applying excessive load (force) to the member to damage the member. In addition, the member opposing surfaces of the pair of columnar portions are not in contact with the member, but are arranged in close proximity to the peripheral surface of the member with a prescribed gap, and therefore, even if the adsorption of the adsorption portion is weakened and the member cannot be held, the member can be prevented from falling and being damaged. In addition, in the case where the member is in contact with the member opposing surface, if a method of re-adsorbing is provided, the member can be removed without being damaged.

[0019] The peripheral surface of the member, that is, the surface directed in a direction perpendicular to the axial direction of the rod-shaped member and perpendicular to the direction in which the pair of columnar portions are opened and closed, can be adsorbed by the adsorption portion. Alternatively, the peripheral surface of the member, that is, the surface directed in the axial direction of the rod-shaped member, can be adsorbed by the adsorption portion.

[0020] That is, any portion of the member can be adsorbed by the adsorption portion depending on the shape or the like of the member to be removed. The member can be engaged or supported by the pair of columnar portions, and therefore, even in the case where the surface of the member has a step or unevenness and the adsorption force is weak, the member can be continuously held and removed. In other words, the member can be engaged or supported by the pair of columnar portions, and therefore, even in the case where the adsorption action is slightly weak, the portion in which the member is not damaged can be adsorbed and removed.

[0021] The method can further include a process of transporting and arranging the member separated from the rod-shaped member to a prescribed destination. In addition, the method can further include a process of transporting and arranging the member separated from the rod-shaped member and adsorbed by the adsorption portion to a preset portion, releasing the adsorption by the adsorption portion, a process of adjusting at least one of the position and the posture of the member arranged in the preset portion, and a process of adsorbing and transporting the adjusted member by a second adsorption portion and arranging the member in a prescribed placement portion. In addition, the method can further include a process of changing the posture of the member with respect to the member after being separated from the rod-shaped member and before being transported, in the middle of being transported, or after being transported and before being arranged. Further, the method can further include at least either one of a process of inspecting the individual member after being separated from the rod-shaped member and before being transported, in the middle of being transported, or after being transported and before being arranged, and a process of inspecting the posture and the position of the arranged member.

[0022] According to this method, the extracted component can be appropriately transported to a desired destination. In addition, according to the method in which the extracted component is placed on the preset portion and re-adsorbed by the second adsorption portion, the extraction and transportation of the component can be performed separately by appropriate adsorption force, and the component can be extracted and transported more safely and efficiently. Further, if the method is configured to change the posture of the component during transportation, the component can be arranged in the destination in a manner suitable for the next process or the like. Further, if the inspection of the component is performed using the inspection unit during transportation, the normal good product can be provided to the next process or the like in an appropriate arrangement.

[0023] In addition, the component can also be an air core coil.

[0024] The air core coil is easily deformed if an excessive force is applied, and it is difficult to reliably maintain the shape of the component in which the wire is wound. As a result, if the component extraction method of the present application is applied, deformation and dropping or the like can be appropriately prevented, and the component can be reliably extracted and transported from the wire winding machine or the like. In particular, the handling of a fine air core coil becomes more difficult, but if it is the component extraction method of the present application that combines contact with only the end peripheral edge using the contact member and adsorption using the adsorption portion, damage and loss (dropping) can be prevented, and extraction and transportation can be appropriately and efficiently performed.

[0025] In addition, the component extraction device of the present application is a component extraction device that extracts a component arranged around a rod-shaped member that is open on one end side, and has:

[0026] an adsorption portion that adsorbs the component arranged around the rod-shaped member;

[0027] a detachment portion that detaches the component from the rod-shaped member by contacting the component from the other end side of the rod-shaped member and moving toward the one end side of the rod-shaped member,

[0028] the adsorption portion moves toward the one end side of the rod-shaped member in a state in which the component is adsorbed, in accordance with the movement of the detachment portion.

[0029] In the component extraction device of the present application, the component is adsorbed by the adsorption portion, and the detachment portion detaches the component from the rod-shaped member by contacting the component, so the mechanical load on the component can be reduced compared to the case in which the component is held and extracted by a holder or the like, and damage to the component can be prevented. In addition, even if the adsorption force is weak, dropping or the like of the component can be prevented compared to the case in which the component is adsorbed only by the adsorption portion. As a result, according to the component extraction device of the present application, the component arranged around the rod-shaped member can be appropriately extracted without being damaged or dropped or the like, for example, in a supply source such as a manufacturing device or a carrying-in device.

[0030] It can also be configured such that the disengagement portion has a pair of columnar portions that are configured to be opened and closed in a direction perpendicular to the axial direction of the rod-shaped member and are movable in the axial direction of the rod-shaped member,

[0031] The pair of columnar portions each has a protrusion that protrudes in the direction in which the pair of columnar portions is opened and closed and that forms a contact surface that contacts the member at the end surface on the side of the one end of the rod-shaped member.

[0032] The pair of columnar portions can also be configured such that the contact surfaces of the pair of columnar portions contact the periphery of the other end side of the member. In addition, the pair of columnar portions can each have a member-facing surface that is disposed opposite the peripheral surface of the member with a prescribed gap. The pair of columnar portions can be configured such that the interval (La) of the member-facing surfaces of the pair of columnar portions and the interval (Lb) of the protrusions of the pair of columnar portions are in the relationship La > W > Lb with respect to the width (W) of the member in the direction in which the pair of columnar portions is opened and closed.

[0033] According to this configuration, the pair of columnar portions, by being configured such that only the contact surfaces contact the periphery of the other end side of the member, movably engage or support the member. Thus, the columnar portions are prevented from exerting excessive load (force) on the member and damaging the member. In addition, the member-facing surfaces of the pair of columnar portions do not contact the member, but are disposed in close proximity to the peripheral surface of the member with a prescribed gap, so even if it is assumed that the member is not held due to weakening of the adsorption of the member by the adsorption portion, the member can be prevented from falling and being damaged. In addition, if configured such that the member is re-adsorbed when the member contacts the member-facing surfaces, the member can be removed without being damaged.

[0034] The adsorption portion can also adsorb the peripheral surface of the member, that is, the surface that faces in a direction perpendicular to the axial direction of the rod-shaped member and perpendicular to the direction in which the pair of columnar portions is opened and closed. Alternatively, the adsorption portion can adsorb the peripheral surface of the member, that is, the surface that faces in the axial direction of the rod-shaped member.

[0035] That is, the adsorption portion can adsorb an arbitrary portion of the member depending on the shape or the like of the member that is the object of removal. The member is engaged or supported by the pair of columnar portions, so even in a situation in which the surface of the member has a step or unevenness and the adsorption force is weakened, the member can be continuously held and removed. In other words, the member is engaged or supported by the pair of columnar portions, so even if the adsorption action is slightly weakened, an appropriate portion can be adsorbed without damaging the member or the like, and the member can be held and removed in cooperation with the pair of columnar portions.

[0036] The system may also include a conveying unit for transporting and placing the component detached from the rod-shaped member at a designated destination. Furthermore, the conveying unit may be configured to include: an adsorption section that transports and places the detached component in a preset section and releases the adsorption; an adjustment section that adjusts at least one of the position and orientation of the component placed in the preset section; and a second adsorption section that adsorbs the adjusted component, transports and places it in a designated mounting section. Additionally, the adsorption section may be configured to rotate in a plane perpendicular to the opening and closing direction of the pair of columnar sections. Moreover, the system may also include an inspection unit that performs at least one of the following checks: an inspection of the component individually after detachment from the rod-shaped member and before transport, during transport, or after transport and before placement, and an inspection of the orientation and position of the placed component.

[0037] According to this structure, the retrieved components can be appropriately transported to the desired destination using the conveying unit. Furthermore, by using an adsorption unit to place the retrieved components in a preset position, adjusting their position using an adjustment unit, and then re-adsorbing them using a second adsorption unit, the retrieval and transport of components can be performed separately using appropriate adsorption forces, enabling safer and more efficient retrieval and transport of components. Moreover, if the structure allows for changing the component's posture during transport, the components can be positioned at the destination in a manner suitable for the next process. Furthermore, if the components are inspected during transport, qualified products can be provided to the next process in an appropriate configuration.

[0038] Alternatively, the component can also be an air-core coil.

[0039] If excessive force is applied to an air-core coil, it is prone to deformation. Furthermore, it is difficult to reliably maintain the shape of a component with the coil wound. However, using the component removal device of the present invention, deformation and drop can be appropriately prevented, allowing for reliable removal and transport from winding machines and the like. In particular, handling fine air-core coils becomes even more difficult. However, with the component removal device of the present invention, which combines a structure where the release part only contacts the end periphery and a structure utilizing the adsorption part, damage and loss (dropping) can be prevented, allowing for proper removal and transport.

[0040] Furthermore, the manufacturing method of the electronic component of the present invention includes a step of removing the electronic component by the above-described component removal method.

[0041] According to this method of manufacturing electronic components, electronic components can be properly removed from manufacturing equipment or handling equipment without being damaged or falling off, thereby improving the overall efficiency of the production line.

[0042] Further, the electronic component manufacturing apparatus of the present application takes out the electronic component by the component taking-out apparatus described above.

[0043] According to the electronic component manufacturing apparatus, the electronic component can be taken out from the manufacturing apparatus or the carrying-in apparatus without being damaged or dropped, and the efficiency of the entire production line can be improved.

[0044] Further, the component placement method of an embodiment of the present application has a step of non-contacting a force to a prescribed portion of a component so that the component having a predetermined surface to be adhered is in a desired adhered state.

[0045] Further, the component placement apparatus of an embodiment of the present application has a unit that non-contactingly applies a force to a prescribed portion of a component so that the component having a predetermined surface to be adhered is in a desired adhered state.

[0046] In the component placement method and the component placement apparatus, since the force is non-contactingly applied to the prescribed portion of the component, the force applied to the component is extremely small compared to the case where the force is applied in mechanical contact with the component. Therefore, the component is not damaged by an excessive load, and the component can be moved with high precision at the prescribed portion. As a result, even if the component is small, the component is not damaged, and the predetermined surface to be adhered of the component can be set in the desired adhered state with extremely small force and with high precision.

[0047] Further, since the force is non-contactingly applied to the prescribed portion of the component, a structure such as a tool or a part of the apparatus does not come into mechanical contact with the component. As a result, the force can be applied to the component without damaging the surface of the component or the like, and the component having the predetermined surface to be adhered can be set in the desired adhered state.

[0048] In the above-described placement method or the above-described placement apparatus, the non-contacting force can be applied to a plurality of the components at the same time.

[0049] In any of the above-described placement methods or the above-described placement apparatuses, the method can further have a step of detecting an adhered state of the component,

[0050] The non-contacting force is applied to at least the prescribed portion of the component that is inappropriate with respect to the detected adhered state of the component.

[0051] In the above-described placement method or the above-described placement apparatus, the detected adhered state of the component can be an angle of the predetermined surface to be adhered of the component.

[0052] In any of the above-described placement methods or the above-described placement apparatuses, the non-contacting force can be applied to the prescribed portion of the component by blowing air to the prescribed portion.

[0053] In any of the placement methods or any of the placement apparatuses described above, the prescribed portion of the component to which the air is blown can be a foot portion of the component in which the adhesion predetermined surface is formed.

[0054] In any of the placement methods or any of the placement apparatuses described above, the air can be blown to the prescribed portion of the component from a direction inclined with respect to a direction perpendicular to the adhesion predetermined surface.

[0055] A method of manufacturing an electronic component according to an embodiment of the present application includes the step of non- contact application of force to a prescribed portion of the electronic component by any of the placement methods described above when the electronic component is adhered to a substrate.

[0056] A manufacturing apparatus of an electronic component according to an embodiment of the present application includes any of the placement apparatuses described above, and non- contact application of force to a prescribed portion of the electronic component when the electronic component is adhered to a substrate.

[0057] The method of manufacturing an electronic component and the manufacturing apparatus according to an embodiment of the present application non- contact application of force to a prescribed portion of the component, and the component having an adhesion predetermined surface is set to a desired adhesion state with high precision without being damaged. Therefore, even a small electronic component can be efficiently manufactured. BRIEF DESCRIPTION OF DRAWINGS

[0164] Embodiments of the present application will be described below with reference to the drawings. The embodiments of the present application described below are examples for describing the present application. Various constituent elements of the embodiments of the present application, such as numerical values, shapes, materials, manufacturing processes, and the like, can be changed or modified within a range in which no problems occur in the technical field.

[0165] In addition, the shapes and the like shown in the drawings of the present application do not necessarily coincide with actual shapes and the like. This is because, for the purpose of explanation, the shapes and the like are sometimes changed.

[0166] Reference Signs Figures 1-31 A coil conveying device of a component pickup method (pickup device) and a component placement method (placement device) to which an embodiment of the present application is applied will be described. The coil conveying device 10 of the present embodiment is a device that conveys a coil 810 formed around a core rod 710 by, for example, an automatic winding machine in a prescribed arrangement and places the coil 810 in a prescribed posture on a placement portion 500 shown in FIG. 1. Figure 7A Figure 7B The coil 810 formed around the core rod 710 by, for example, the automatic winding machine in a prescribed arrangement and in a prescribed posture shown in FIG. 1 is conveyed to the placement portion 500 shown in FIG. 1. Figure 25B Figure 26B The coil 810 formed around the core rod 710 by, for example, the automatic winding machine in a prescribed arrangement and in a prescribed posture shown in FIG. 1 is conveyed to the placement portion 500 shown in FIG. 1. Figure 14A Figure 14B The coil 810 formed around the core rod 710 by, for example, the automatic winding machine in a prescribed arrangement and in a prescribed posture shown in FIG. 1 is conveyed to the placement portion 500 shown in FIG. 1.

[0167] ​​​More specifically, the coil conveying device 10 takes out (pulls out) the air core coil 810 wound around the mandrel 710 from the mandrel 710, conveys it to the placement section 500, and places it on the placement section 500. The placement section 500 is, for example, an adhesive sheet (adhesion sheet) for supplying the air core coil 810 to an outer seal process for manufacturing a coil member, and the air core coil 810 is placed in a two-dimensional arrangement on the adhesion surface 510. At this time, for example, in a case where the air core coil 810 is placed with the foot (adhesion predetermined surface) floating, or the like, the placement state (adhesion state) is inappropriate, the coil conveying device 10 corrects the placement state of the air core coil 810 and sets it to an appropriate posture.

[0168] Further, for example, as shown in Figure 24 , the electronic component of the present application manufactured by performing the outer seal process on the air core coil 810 placed on the placement section 500 is an electronic component in which the air core coil (coil portion) 810 as an electronic element is sealed and housed inside the base body 910, that is, a coil member 900 in which the air core coil is embedded in the base body 910. The coil member 900 has the base body 910 and the coil portion 810, and the coil portion 810 has a winding portion 812 and a foot portion 813a, 813b as a pair of electrode terminals.

[0169] In addition, the coil member 900 is a small electronic component having, for example, a length of the largest side in the planar direction of 5 mm or less, or 3 mm or less, or 0.6 mm or less, and a height of, for example, 3 mm or less, or 2 mm or less, or 0.3 mm or less.

[0170] Hereinafter, such a coil conveying device 10 will be described in detail.

[0171] The coil conveying device 10 has Figures 1-2B an operation section 100 as shown in Figures 3A-4 an adsorption nozzle 210 as shown in Figures 13A-14B a conveying nozzle 220 as shown in Figures 13A-13C a preset section 300 as shown in Figure 25A and an air jet nozzle 241 as shown in. In addition, the coil conveying device 10 has sensors and a camera that detect the position, posture, and action state of each constituent part and the conveying target member.

[0172] In addition, the coil conveying device 10 has a drive section that drives each constituent part including the operation section 100, the adsorption nozzle 210, and the air jet nozzle 241. In addition, the coil conveying device 10 has a suction device that suctions air via the adsorption nozzle 210, and an air jet device that jets air via the air jet nozzle 241. In addition, the coil conveying device 10 has a control section (arithmetic processing device) that controls each constituent section and performs processing related to the inspection of the conveying target member.

[0173] The structure of each part will be described below.

[0174] As shown in Figure 10A and Figure 10B , the operation part 100 is a member for engaging (hanging) the empty coil 810 of the extraction object between the columnar parts 101a, 101b and pulling out from the core rod 710.

[0175] As shown in Figure 1 , the operation part 100 has a pair of columnar parts 101a, 101b disposed opposite to each other. The columnar parts 101a, 101b each have a prismatic main body 103. In the columnar part main body 103, the front end part 104 as one end part is configured as a free end, and the base end part as the other end part is connected to a not-shown drive device.

[0176] Further, with reference to Figure 1 , as illustrated, the extending direction of the pair of columnar parts 101a, 101b is set as the Z-axis direction, the base end part side (Z-axis positive direction) is set as the upper side (upward direction), and the front end part 104 side (Z-axis negative direction) is set as the lower side (downward direction). In addition, the direction opposite to the pair of columnar parts 101a, 101b is set as the X-axis direction, and the direction perpendicular to the Z-axis direction and the X-axis direction is set as the Y-axis direction.

[0177] A protrusion 140 is formed at each of the front end parts 104 of the pair of columnar parts 101a, 101b, and the protrusion 140 protrudes toward the columnar part 101b, 101a on the opposite side at a prescribed small height W1. Therefore, a step face 141 is formed at the opposite face (columnar part inner side face) 151 of the columnar part main body 103. The step face 141 is the side face of the base end side of the protrusion 140.

[0178] The step face 141 has a contact face 142 on one side in the Y-axis direction and a widened part 143 on the other side in the Y-axis direction. The contact face 142 is a portion whose length in the X-axis direction is constant, and the widened part 143 is a portion whose length in the X-axis direction gradually widens away from the contact face 142. The widened part 143 becomes a shape whose width gradually widens in correspondence with the fact that the columnar part inner side face 151 adjacent to the upper side thereof is formed as an inclined face 153 whose distance between the opposite pair of columnar parts 101a, 101b gradually widens. The portion 152 of the columnar part inner side face 151 adjacent to the upper side of the contact face 142 is formed as a parallel face whose distance between the opposite pair of columnar parts 101a, 101b does not change.

[0179] In each of the columnar portions 101a, 101b, a surface adjacent to the step surface 141 of the convex portion 140 is an inner end surface 145 parallel to the Z-axis direction, and is the closest (shortest distance) portion in the pair of columnar portions 101a, 101b. A portion further toward the front end side from the inner end surface 145 is formed as a sloped surface 146 gradually expanding the distance between the opposite columnar portions 101a, 101b.

[0180] The pair of columnar portions 101a, 101b of this shape are configured to be connected to a drive portion not shown at the base end side and to be movable in the X direction, respectively. That is, the pair of columnar portions 101a, 101b are configured to be able to arbitrarily change the interval (distance) therebetween. In the present embodiment, when the pair of columnar portions 101a, 101b handle (extract) the specific air core coil 810, the pair of columnar portions 101a, 101b are at least opened and closed (moved) to a prescribed open state corresponding to the size of the air core coil 810 and a prescribed closed state corresponding to the size of the air core coil 810.

[0181] In addition, the operation portion 100 having the pair of columnar portions 101a, 101b that are openable and closable as a whole is further connected as a whole to a drive portion not shown, and the pair of columnar portions 101a, 101b are integrally configured to be able to move in parallel or rotate in any direction. The operation portion 100 is configured to be able to integrally rise or fall in the vertical direction, or move in the horizontal direction, or rotate about an arbitrary direction as a rotation axis, in the closed state or the open state of the pair of columnar portions 101a, 101b.

[0182] The operation portion 100 of this shape is configured such that, in the pair of columnar portions 101a, 101b, Figure 5 as shown, the contact surfaces 142, 142 of the columnar portions 101a, 101b come into contact with the air core coil 810 that is the extraction (pull-out) object, and engage or support the same. In the operation portion 100, the contact surfaces 142, 142 are the only surfaces (portions) that come into contact with the air core coil 810.

[0183] The portions 152, 152 of the columnar portion inner surfaces 151, 151 adjacent to the contact surfaces 142, 142 are component opposing surfaces that oppose the peripheral surface of the air core coil 810 when the air core coil 810 is engaged by the operation portion 100. The component opposing surfaces 152, 152 are disposed in close proximity to the peripheral surface of the air core coil 810, but are disposed apart from the peripheral surface of the air core coil 810 by a prescribed small interval, and do not come into contact with the peripheral surface of the air core coil 810.

[0184] Figure 5 The state in which the pair of columnar portions 101a, 101b are closed in order to extract the air core coil 810 wound around the mandrel 710 from the mandrel 710 is shown. As shown, the contact surfaces 142, 142 of the pair of columnar portions 101a, 101b are in contact with the air core coil 810, and the air core coil 810 is engaged by the pair of columnar portions 101a, 101b.Figure 5 As shown, the columnar portions 101a and 101b make the contact surfaces 142 and 142 contact the periphery of the bottom surface of the air coil 810, while the opposing surfaces 152 and 152 of the components do not contact the air coil 810.

[0185] In order to engage with the air-core coil 810 in this state, a pair of columnar portions 101a and 101b are designed to satisfy the relationship: La > W > Lb when they are closed (W: the width of the air-core coil 810 in the opening and closing direction of columnar portions 101a and 101b, La: the interval between the opposite surfaces 152 and 152 of columnar portions 101a and 101b, Lb: the interval between the inner end faces 145 and 145 of columnar portions 101a and 101b), and are controlled to open and close.

[0186] In addition, the inner end faces 145, 145 of the pair of columnar portions 101a, 101b of the operation section 100 are designed not to contact the mandrel 710 or control the opening and closing of the columnar portions 101a, 101b when the columnar portions 101a, 101b are closed.

[0187] The height W1 of the protrusion 140 of the operating part 100, i.e. the width W1 of the contact surface 142 and the length W2 of the contact surface 142 in the Y direction, can be appropriately set according to the size of the hollow coil 810 to be removed and the winding diameter. For example, the width W1 of the contact surface 142 can also be smaller than the diameter of the winding forming the hollow coil 810.

[0188] In addition, such as Figure 5 As shown, when the hollow coil 810 is pulled out from the vertically positioned core rod 710, the operating part 100 not only engages the contact surface 142 with the hollow coil 810 to move it, but also supports the hollow coil 810 from below in the vertical direction. On the other hand, when the hollow coil 810, which is positioned on a horizontally positioned rod member, is pulled out horizontally, the operating part 100 moves the hollow coil 810 simply by engaging the contact surface 142 with it, without supporting the hollow coil 810. The function of the operating part 100 varies depending on the method of supplying the component to be removed, but in the coil conveying device 10 of this embodiment, the operating part 100 holds and conveys the hollow coil 810 together with the suction nozzle 210 described below, so it is sufficient to at least engage with and move the component.

[0189] In the operating section 100, the widened portion 153 of the inner side surface, the widened portion 143 of the stepped surface 141, and the inclined surface 146 on the front end portion 104 side of the inner end face 145 are formed as so-called clearance space or space allowance, so as not to interfere with the air core coil 810 or other machinery, appliances, or devices during the aforementioned removal operation of the air core coil 810. By adopting this structure, the operating section 100 can operate safely.

[0190] Furthermore, in the operating section 100, the opposing surfaces 152, 152 of each component of the pair of columnar portions 101a, 101b are mirror-finished. When the air-core coil 810 is normally engaged using the operating section 100, as described above, the opposing surfaces 152, 152 do not contact the air-core coil 810. However, due to various reasons such as an imbalance in the posture of the air-core coil 810, the air-core coil 810 may sometimes come into contact with the opposing surfaces 152. To prevent damage to the air-core coil 810 or to reduce damage in such cases, the opposing surfaces 152, 152 are mirror-finished.

[0191] like Figure 3A and Figure 3B As shown, the adsorption nozzle 210 is a component used to adsorb and hold the air-core coil 810.

[0192] The adsorption nozzle 210 is a cylindrical member with a connecting passage 202 formed inside. At one end, the front end 204 has an end opening of the connecting passage 202, namely the front adsorption hole 205. The other end of the adsorption nozzle 210 is connected to a suction device via a tube (not shown). The suction device operates by drawing air from the front adsorption hole 205 at the front end 204 of the adsorption nozzle 210. As a result, a negative pressure is generated at the front adsorption hole 205, which adsorbs the air-core coil 810 that is in contact with the front adsorption hole 205.

[0193] like Figure 4 As shown, the outer diameter S1 of the adsorption nozzle 210 can be greater than the magnetic path length (equivalent to the height of the hollow coil 810 acting as a coil) L1 of the hollow coil 810 that is being removed, or the end of the adsorption nozzle 210 can protrude from the circumference of the hollow coil 810 as shown. On the other hand, it is preferable that the aperture S2 of the front adsorption hole 205 is smaller than the magnetic path length L1 of the hollow coil 810. More preferably, the aperture S2 of the front adsorption hole 205 is 40% to 90% of the magnetic path length L1 of the hollow coil 810. Furthermore, the shape of the hole of the adsorption nozzle can be circular, oblong, or square. In this case, the outer diameter S1 is equivalent to the length of the longest part of the hole. (For example, in the case of a circular hole, it is equivalent to the diameter, and in the case of a square hole, it is equivalent to the diagonal length.)

[0194] Further, the front end portion 204 of the suction nozzle 210 can also be composed of a porous body formed with a plurality of fine holes, instead of a structure with one front end suction hole 205. The suction force from the suction device via the communication path 202 of the suction nozzle 210 is imparted to the air core coil 810 via the fine holes of the porous body, and is effective for suctioning the fine air core coil 810 or the air core coil 810 with a lot of concave-convex on the peripheral surface, and the like.

[0195] The material of the suction nozzle 210 is not particularly limited, and for example, a metal steel material such as stainless steel is preferably used.

[0196] The front end portion 204 of the suction nozzle 210 is surface-coated with a suitable material in a manner not to damage the air core coil 810 contacted by the front end portion 204.

[0197] The suction nozzle 210 of this shape is connected to a not-shown driving portion, and can be moved in parallel or rotationally moved in an arbitrary direction. The suction nozzle 210 is configured to be able to be raised or lowered in the vertical direction, or moved in the horizontal direction, or rotationally moved with an arbitrary direction as a rotation axis, integrally with or independently from the operation portion 100 described above.

[0198] Further, the operation portion 100 and the suction nozzle 210 described above can also be configured to be integrally driven and controlled by the same driving device and control device. As described below, the operation portion 100 and the suction nozzle 210 can also be configured to be able to be rotationally moved with the same fulcrum as an axis, and the parts that can be commonly used are integrally driven by the same driving device. If configured thus, the device structure can be simplified, and is thus preferable.

[0199] The preposition portion 300 is a structure for temporarily placing and re-suctioning the air core coil 810 taken out from the core rod 710 by the operation portion 100 and the suction nozzle 210.

[0200] As shown in FIG. 6, the preposition portion 300 has a preposition table 310, a positioning member 320, and a not-shown airflow generating device. Figures 13A-13C The preposition table 310 is a base table for temporarily placing the air core coil 810 taken out from the core rod 710 by the operation portion 100 and the suction nozzle 210. The surface of the preposition table 310 is processed to be easily slidable, and the placed air core coil 810 can be easily moved.

[0201] As shown in FIG. 7, the positioning member 320 is an L-shaped member, and is fixedly provided to the upper surface of the preposition table 310. As shown in FIG. 8, the positioning member 320 is provided with a plurality of positioning holes 321.

[0202] Figure 13A As shown in FIG. 7, the positioning member 320 is an L-shaped member, and is fixedly provided to the upper surface of the preposition table 310. As shown in FIG. 8, the positioning member 320 is provided with a plurality of positioning holes 321. Figure 13B ​As shown, the air core coil 810 placed on the upper surface of the pre-setting table 310 is moved toward the inner side corner portion of the positioning member 320 by the air flows f1, f2, whereby the position and posture of the air core coil 810 are accurately specified as the position and posture along the inner side corner portion of the positioning member 320.

[0203] As shown, the air core coil 810, the position and posture of which are thus accurately adjusted, is this time re-adsorbed by the transport nozzle 220 and transported to the placement portion 500 as a transport destination. Figure 13C

[0204] In the coil transport device 10 of the present embodiment, when the air core coil 810 is handed over from the adsorption nozzle 210 to the transport nozzle 220, in order to adsorb the air core coil 810 in a proper position and posture, such a pre-setting portion 300 is used.

[0205] As described above, the transport nozzle 220 is an adsorption member for transporting the air core coil 810 from the pre-setting portion 300 to the placement portion 500. In the present embodiment, the transport nozzle 220 is the same structure as the adsorption nozzle 210.

[0206] The placement portion 500 is a destination for transporting the air core coil 810, and is a member for placing the transported air core coil 810 in a specified arrangement. Generally, the placement portion 500 is a member handover portion (position) for supplying the air core coil 810 to the next process. In the present embodiment, the placement portion 500 is an adhesive sheet for supplying the air core coil 810 to the outer seal process as the next process. As shown, Figures 14A-16B

[0207] However, the specific structure of the placement portion 500 is not limited to this, and can be a tray provided with recesses for housing each air core coil 810, a belt member provided with bags for housing each air core coil 810, or the like. In addition, it can be a part such as a component feed port (supply port) in a processing machine of the next process, rather than a transport member.

[0208] The coil transport device 10 is omitted from the illustration, but has a plurality of cameras.

[0209] The cameras are provided in plurality throughout the entire coil transport device 10, but are roughly classified into cameras of a first system as a sensor unit for controlling the coil transport device 10, cameras of a second system for inspecting the air core coil 810 as a component to be taken out and transported, and cameras of a third system for inspecting the arrangement state and placement state of the air core coil 810 in the placement portion 500 as a transport destination.

[0210] ​​The camera in the first system captures images of the formation state of the hollow coil 810 toward the core rod 710, the movement and position of the columnar portions 101a, 101b and the suction nozzle 210, the support state, suction state, and holding state of the hollow coil 810 by the columnar portions 101a, 101b and the suction nozzle 210, and the position and posture of the hollow coil 810 placed on the preset part 300. In addition, to understand the relative positional relationships and operating conditions of the various components constituting the coil conveying device 10, it also captures images of the object and sends the obtained image data to the control unit. Based on this data, the control unit detects the operating status of the coil conveying device 10 and controls each component using a control method including so-called feedback control to make the coil conveying device 10 perform the desired actions.

[0211] The second system's camera, for example, captures images of the hollow coil 810 being adsorbed and transported by the adsorption nozzle 210 or the transport nozzle 220, and sends the obtained image data to the control unit. Based on this data, the control unit monitors the state of the hollow coil 810 as a single component, including its appearance, the position and shape of the terminals, and the bonding status of the lead terminals, and performs processes such as determining good / bad products, marking and eliminating defective products.

[0212] The camera of the third system captures images of the air-core coil 810 placed in the mounting section 500 and sends the obtained image data to the control unit. Based on this data, the control unit detects the mounting state of the air-core coil 810, namely the mounting position, posture, and shape of the air-core coil 810, and determines whether it is appropriate. The determination of appropriateness (good or bad judgment) is performed as follows: detecting the tilt of the air-core coil 810 and the spacing between the air-core coils 810, predicting the position, posture, and shape of a specific air-core coil 810, and determining whether it is within the specified range.

[0213] Specifically, for example Figure 16A or Figure 16B As shown, in the case of air-core coils 810a to 810f having an adhesive surface 510 placed on the mounting portion 500, air-core coil 810d is judged to be defective if it is placed at a large angle within the adhesive surface 510. Furthermore, air-core coil 810f is judged to be defective if it is placed at a large angle in the vertical direction relative to the adhesive surface 510. The other air-core coils 810a to 810c and 810e are properly arranged and within the specified range, and are judged to be good products.

[0214] As a third system camera, it is preferable to have a camera with at least an adhesive surface 510 for photographing the mounting portion 500 from its upper surface, so as to be able to acquire... Figure 16Aimage data as shown. In addition, as the camera of the third system, for example, there can be a camera that captures the air core coil 810 placed on the placement portion 500 from the side direction (or the oblique upper direction or the oblique side direction) at the height level of the adhesive surface 510 to be able to acquire Figure 16B image data as shown.

[0215] However, in the detection of the placement state, the placement posture, and the shape of the air core coil 810 in the control portion, not only the image data transmitted from the camera of the third system, but also the image data transmitted from the cameras of the first system and the second system are used. Thereby, as the camera of the third system, even if the camera that captures the adhesive surface 510 of the placement portion 500 from the side direction is not provided, the shape of the foot portion of the air core coil 810 that cannot be captured from the upper surface can be detected, and the like.

[0216] As for the air core coil 810 in which the disposition on the surface parallel to the adhesive surface 510 is inappropriate among the air core coils 810 judged to be defective, the air core coil 810 is directly judged to be a defective product, and a treatment such as a mark of the defective product is performed. This is because the disposition is not easy to change since the position of the adhesion of the air core coil 810 and the adhesive surface 510 needs to be changed.

[0217] On the other hand, as for the air core coil 810 in which the placement posture and the shape are inappropriate among the air core coils 810 judged to be defective, a treatment of correcting the placement posture and the shape of the air core coil 810 is performed. For example, as shown in Figure 25A the correction of the placement posture and the shape of the air core coil 810 is performed by blowing air to the prescribed position corresponding to the inappropriate state of the air core coil 810 using the air jet nozzle 241. As a reason thereof, this defect can be corrected without peeling the portion already adhered to the adhesive surface 510 from the adhesive surface 510.

[0218] In the present embodiment, the air core coil 810 in which the correction of the placement posture and the shape is performed is directly transported to the next process. However, the air core coil 810 in which the correction of the placement posture and the shape is performed by the blowing of air by the air jet nozzle 241 can be captured again in the placement state, and it is judged whether the placement state is appropriate. As a result, the air core coil 810 judged to be appropriate (judged to be appropriately corrected) is judged to be a good product, and the air core coil 810 judged to be inappropriate in the placement state is judged to be a defective product, and a treatment such as a mark can be performed. In addition, in the case where the inappropriate state of the placement posture and the shape of the air core coil 810 is a kind or a degree that cannot be corrected by the blowing of air, the correction of the placement posture and the shape can not be performed by the blowing of air by the air jet nozzle 241, and the defective product can be directly judged, and a treatment such as a mark of the defective product can be performed.

[0219] Further, the mark or the like is not only a physical mark but also a data processing mark.

[0220] Further, in the description of the component conveying method, as a description of the component arrangement state checking (check 2) step S10 (refer to Figure 6 ), a more specific checking method of the placement state of the air core coil 810 is described later.

[0221] Further, in the processing of the captured image data generated using these cameras, the sensor that can be used can also be a sensor other than the camera (capturing unit).

[0222] As shown in Figure 25A , the air injection nozzle 241 is a member for injecting air to the air core coil 810. The air injection nozzle 241 blows air to a prescribed position corresponding to a bad state of the air core coil 810, and corrects (changes) the posture and shape thereof.

[0223] Referring to Figure 3A and Figure 3B , the air injection nozzle 241 has substantially the same structure as the above-described suction nozzle 210. That is, the air injection nozzle 241 is a cylindrical member in which a communication path 202 is formed inside, and an end portion opening of the communication path 202 is formed at a front end portion 204 that is one end portion. The other end portion of the air injection nozzle 241 is connected to an air sending device such as a compressor via a pipe not shown, and by injecting air sent through the pipe from the opening of the front end portion 204 of the air injection nozzle 241, air of a prescribed pressure is blown to a prescribed portion of the air core coil 810.

[0224] The blown air pressure is a pressure that can change the placement posture and shape of the air core coil 810 within a range in which the air core coil 810 does not peel off (is blown away) from the adhesive surface 510, that is, a pressure that can correct the placement posture and shape. Further, in the description of the component conveying method, as a description of the component placement state correction step S11 (refer to Figure 6 ), a portion of the air core coil 810 to which air is blown is described later.

[0225] In addition, the material of the air injection nozzle 241 is not particularly limited, and for example, a metal steel material such as stainless steel can be used.

[0226] The air injection nozzle 241 is provided at a driving portion not shown, and can be moved to the adhesive surface 510 of the placement portion 500 (refer to Figure 16A and Figure 16B) on the adhesion surface 510 of the placement portion 500 at an arbitrary angle with respect to a direction perpendicular to the adhesion surface 510. If this is the case, the air injection nozzle 241 can blow air at an arbitrary angle to an arbitrary position of the air core coil 810 placed on the adhesion surface 510 of the placement portion 500. Therefore, it is possible to correct the placement posture of a plurality of (many) air core coils 810 placed on the adhesion surface 510 of the placement portion 500 at a relatively narrow pitch, and the like, with one air injection nozzle 241, and it is possible to make the structure of the coil conveying device 10 simple.

[0227] However, the coil conveying device 10 can also be configured to have a plurality of air injection nozzles. For example, as shown in Figure 29 , it can also be configured to have two air injection nozzles 241, 241, so as to be able to blow air to both leg portions 813a, 813b of one air core coil 810 at the same time.

[0228] In this configuration, the plurality of air injection nozzles 241,..., 241 (for example, two air injection nozzles 241, 241) can also be configured so as to be able to be moved at an arbitrary angle and to be able to blow air to an arbitrary position on the adhesion surface 510 independently of each other by a control portion and a drive portion, which are not shown. Alternatively, for example, it can also be configured so that a predetermined plurality of air injection nozzles 241,..., 241 are able to be moved at an arbitrary angle and to be able to blow air to an arbitrary position on the adhesion surface 510 integrally with respect to a certain predetermined plurality of air injection nozzles 241,..., 241. Alternatively, it can also be configured so that, with respect to a predetermined plurality of air injection nozzles 241,..., 241, it is possible to move integrally to an arbitrary position on the adhesion surface 510, and on the other hand, at the position of the movement, it is possible to adjust the position or the angle of each air injection nozzle 241, and it is possible to blow air to each target portion with respect to each air injection nozzle 241.

[0229] By being configured in this way, it is possible to blow air to a plurality of air core coils 810 or to a plurality of defective portions at the same time in parallel, the placement efficiency of the air core coil 810 is improved, and furthermore, it is possible to efficiently manufacture the coil member 900 (refer to Figure 24 ).

[0230] Alternatively, for example, as shown in Figure 30 and Figure 31As shown, two air jet nozzles 241, 241 can be fixedly provided with respect to each of the plurality of (many) air core coils 810 placed on the adhesion surface 510. Using these air jet nozzles 241,..., 241, air is blown to all the air core coils 810 placed on the adhesion surface 510 by a control section and a driving section not shown, whereby the placement state of all the air core coils 810 placed on the adhesion surface 510 can be simultaneously corrected, the placement efficiency of the air core coils 810 is further improved, and the manufacturing of the coil member 900 can be performed more efficiently.

[0231] Further, in the structure in which the air jet nozzles 241, 241 are fixedly provided with respect to the foot portions 813a, 813b of all the air core coils 810 placed on the adhesion surface 510, the air core coils 810 having an inappropriate placement posture and shape via the camera of the third system or the like can not be subjected to the detection process. By blowing air to all the air core coils 810,..., 810 including the air core coils 810 placed in an appropriate placement state, as a result, the air core coils 810 in a poor placement state are selectively corrected in the placement state, and the structure and processing time involved in the process of detecting the poor air core coils 810 can be omitted.

[0232] Further, as shown in Figure 16A and Figure 16B A plurality of air core coils 810 are arranged on the adhesion surface 510 of the placement section 500 at a prescribed pitch D8 (X direction) and D9 (Y direction) from the adjacent air core coils 810. In addition, as described above, in the present embodiment, the air core coils 810 themselves are extremely small (minute) in size, for example, 0.6 mm x 0.6 mm x 0.3 mm or less, and the arrangement pitches D8, D9 are also generally narrow.

[0233] Therefore, as shown in Figure 30 and Figure 31 In the structure in which a plurality of air jet nozzles 241, 241 are fixedly provided with respect to the foot portions 813a, 813b of all (or a plurality of) air core coils 810,..., 810 placed on the adhesion surface 510, each air jet nozzle 241,..., 241 is arranged at a position and an angle such that it does not interfere with the adjacent air jet nozzle 241. Alternatively, the arrangement pitch of the air core coils 810,..., 810 on the adhesion surface 510 of the placement section 500 is determined in such a manner that the air jet nozzles 241,..., 241 can be arranged in this manner.

[0234] The structure of the coil conveying device 10 is described above. The operation of each part of the coil conveying device 10 is controlled and performed by a control section not shown. The coil conveying device 10 has a control section for the operation. The control section can be a processor provided in the coil conveying device 10 or a general-purpose computer connected via a communication I / F.

[0235] Next, the operation of the coil conveying device 10 will be described with reference to Figures 6-16B The process of taking out the empty coil 810 and conveying it to the conveying destination using the coil conveying device 10 having such a structure will be described.

[0236] Further, in the following description with reference to Figures 7A-12B , the vertical direction is set as the Z-axis direction, the opening and closing direction of the columnar portions 101a and 101b of the operation section 100 at the time of taking out the empty coil 810 formed on the mandrel 710 is set as the X-axis direction, and the direction perpendicular to the Z-axis direction and the X-axis direction is set as the Y-axis direction. In addition, the Z-axis positive direction is sometimes referred to as up, the Z-axis negative direction side is sometimes referred to as down, the Y-axis negative direction is sometimes referred to as front, and the Y-axis positive direction is sometimes referred to as rear.

[0237] Figure 6 is a flowchart showing the process thereof.

[0238] First, as shown in Figure 7A and Figure 7B , the empty coil 810 to be taken out and conveyed is formed on the mandrel 710 (step S1). In the present embodiment, the mandrel 710 is a winding core shaft on which a wire is wound using an automatic winding machine not shown. The mandrel 710 is provided on the base 700. The base 700 can be a structure attached to the automatic winding machine or a member different from the automatic winding machine. In addition, the mandrel 710 can be provided in a plurality on the base 700.

[0239] The mandrel 710 is a rod-shaped member extending upward in the vertical direction (Z-axis direction) from the base 700, and the upper end portion is configured as an open free end. On the mandrel 710, a wire is sequentially wound using the automatic winding machine not shown to form the coil 810. In the present embodiment, the wire wound on the mandrel 710 is a round wire 811 (see Figure 4 ).

[0240] Further, in Figures 7A-12B , from the viewpoint of explaining the process and state of winding the wire on the mandrel 710, both end portions of the wire constituting the empty coil 810 are illustrated in the state of a round wire. However, although detailed description is omitted, for the empty coil 810, for example, in the state of being wound on the mandrel 710 or being supplied to a foot portion forming unit not shown while being placed in front of the pre-setting table 300, as shown in Figure 14A , foot portions 813a and 813b are formed.

[0241] In the present embodiment, the leg portions 813a, 813b are formed by providing a flat member at both end portions of the wire constituting the air core coil 810, or by flattening both end portions of the wire by a flattening process. However, the leg portions 813a, 813b can be any shape as long as the air core coil 810 can stand by itself, and can be formed by any method.

[0242] If the preparation of the air core coil 810 is completed, that is, the manufacturing of the air core coil 810 with respect to the core rod 710 is finished, the operation portion 100 of the coil conveying device 10 is moved to the vicinity of the air core coil 810, and the air core coil 810 is sucked by the suction nozzle 210 (step S2).

[0243] To this end, first, as shown in Figs. 9A and 9B, the pair of columnar portions 101a, 101b and the suction nozzle 210 are lowered (moved downward in the Z-axis direction). At this time, the pair of columnar portions 101a, 101b are in an open state. As for the suction nozzle 210, the position of lowering is a position at which the front end suction hole 205 of the front end portion 204 and the peripheral surface of the air core coil 810 become the same height, and as for the pair of columnar portions 101a, 101b, the position of lowering is a position at which the contact surfaces 142, 142 of the columnar portions 101a, 101b become more on the lower side than the bottom surface of the air core coil 810. Figure 8A Figure 8B Next, as shown in Figs. 10A and 10B, the pair of columnar portions 101a, 101b and the suction nozzle 210 are advanced. That is, the columnar portions 101a, 101b and the suction nozzle 210 are moved in the Y-axis direction to the direction of approaching the air core coil 810. The columnar portions 101a, 101b are moved to a position at which the Y-axis direction position of the contact surfaces 142, 142 of the columnar portions 101a, 101b is the same as the Y-axis direction position at which the contact surfaces 142, 142 of the bottom peripheral portion of the air core coil 810 are in contact. The suction nozzle 210 is moved to a position at which the front end portion 204 is in abutment with the peripheral surface of the air core coil 810.

[0244] Next, as shown in Figs. 10A and 10B, the pair of columnar portions 101a, 101b and the suction nozzle 210 are advanced. That is, the columnar portions 101a, 101b and the suction nozzle 210 are moved in the Y-axis direction to the direction of approaching the air core coil 810. The columnar portions 101a, 101b are moved to a position at which the Y-axis direction position of the contact surfaces 142, 142 of the columnar portions 101a, 101b is the same as the Y-axis direction position at which the contact surfaces 142, 142 of the bottom peripheral portion of the air core coil 810 are in contact. The suction nozzle 210 is moved to a position at which the front end portion 204 is in abutment with the peripheral surface of the air core coil 810. Figure 9A Figure 9B If the front end portion 204 of the suction nozzle 210 is in contact with the air core coil 810, air is sucked via a not-shown suction device and via the communication path 202 of the suction nozzle 210. Thus, a negative pressure is generated at the front end suction hole 205 of the suction nozzle 210, and the peripheral surface of the air core coil 810 is vacuum-sucked to the front end portion 204 of the suction nozzle 210, becoming a state in which the air core coil 810 is held by the suction nozzle 210.

[0245] If the front end portion 204 of the suction nozzle 210 is in contact with the air core coil 810, air is sucked via a not-shown suction device and via the communication path 202 of the suction nozzle 210. Thus, a negative pressure is generated at the front end suction hole 205 of the suction nozzle 210, and the peripheral surface of the air core coil 810 is vacuum-sucked to the front end portion 204 of the suction nozzle 210, becoming a state in which the air core coil 810 is held by the suction nozzle 210.

[0246] ​​At this time, the adsorption of the hollow coil 810 by the adsorption nozzle 210 is directed towards the surface of the hollow coil 810 that points in the direction perpendicular to the opening and closing direction (x direction) of the columnar portions 101a and 101b (the adsorption nozzle 210 is oriented towards the surface in the y direction). The adsorption part of the adsorption nozzle 210 can adsorb any part that can be adsorbed without interfering with the operating part 100 and the core rod 710.

[0247] Furthermore, the circumferential surface of the hollow coil 810 is curved, and there are recesses between the wound circular wires 811. Therefore, even when suction is applied using the suction nozzle 210, leakage occurs, making it difficult to achieve a tight seal. However, if suction is applied with a certain level of force, the suction nozzle 210 can absorb even some leakage. In addition, in the coil conveying device 10, the operating unit 100 simultaneously engages and supports the hollow coil 810. Therefore, even if the suction force is slightly reduced, the hollow coil 810 can be properly held in cooperation with the operating unit 100.

[0248] Next, as Figure 10A and Figure 10B As shown, the operation unit 100 is closed (process S3). That is, the pair of columnar parts 101a and 101b are moved inward respectively. The pair of columnar parts 101a and 101b are moved to become a reference. Figure 5 The aforementioned positional relationship is as follows: Contact surfaces 142, 142 are positioned below the bottom surface of the hollow coil 810 (in the engaging and pulling-out positions), and inner end faces 145, 145 are positioned not in contact with the side surface 715 of the core rod 710. Furthermore, the opposing surfaces 152, 152 are positioned close to the circumferential surface of the hollow coil 810, but at a predetermined distance from it. At this time, as... Figure 10A and Figure 10B As shown, the contact surfaces 142, 142 of the columnar portions 101a, 101b are positioned at a predetermined interval from the bottom surface of the air-core coil 810, without contacting it.

[0249] Thus, if the adsorption nozzle 210 adsorbs the hollow coil 810, and the contact surfaces 142 of the columnar portions 101a and 101b are positioned in the pull-out position, then... Figure 11A and Figure 11B As shown, the operating part 100 and the adsorption nozzle 210 are raised, and the hollow coil 810 is pulled out from the core rod 710 (process S4).

[0250] The contact surfaces 142, 142 of the columnar portions 101a and 101b are located on the lower side of the air coil 810 in the Z-axis direction. Therefore, when the columnar portions 101a and 101b rise, the contact surfaces 142, 142 contact the air coil 810, and the air coil 810 moves upward together with the columnar portions 101a and 101b.

[0251] At this time, the adsorption nozzle 210 continues to adsorb the hollow coil 810 and moves upward together with the hollow coil 810. Therefore, the adsorption nozzle 210 starts moving upward after the beginning of the upward movement of the pair of columnar portions 101a and 101b, and begins to move upward when the contact surfaces 142 and 142 of the columnar portions 101a and 101b come into contact with the lower surface of the hollow coil 810. Thus, while maintaining the adsorption of the adsorption nozzle 210, the hollow coil 810 is moved upward and disengaged from the core rod 710 by the engagement of the contact surfaces 142 and 142 of the operating portion 100.

[0252] If the air coil 810 detaches from the core rod 710, the air coil 810 is conveyed to the preset section 300 (process S5).

[0253] In this embodiment, the operating unit 100 and the adsorption nozzle 210 convey the hollow coil 810 to the upper part of the preset unit 300 while the hollow coil 810 is being pulled out from the mandrel 710. When the hollow coil 810 is conveyed in this manner, its bottom end is supported by the contact surfaces 142, 142 of the columnar portions 101a, 101b. Therefore, it will not fall off even if the adsorption force of the adsorption nozzle 210 is released. Furthermore, in the event that the adsorption of the adsorption nozzle 210 is accidentally released, a mechanism and control unit can be provided to detect this situation and re-adsorb.

[0254] If the air coil 810 is transported to the upper part of the preset section 300, the air coil 810 is temporarily placed on the preset stage 310 (process S6).

[0255] like Figure 12A and Figure 12B As shown, the operating unit 100 and the suction nozzle 210 rotate approximately 90° around the X-axis, so that the foot of the hollow coil 810 is positioned vertically downwards, and the suction nozzle 210 is positioned to suction the hollow coil 810 from above. Thus, the hollow coil 810 is positioned to be placed in the preset section 300. Furthermore, this rotation releases the support of the hollow coil 810 provided by the operating unit 100, causing the pair of columnar portions 101a and 101b to open outwards and retract to a separated position so as not to interfere with the hollow coil 810.

[0256] If the air core coil 810 becomes in a posture that can be placed on the preposition part 300, the suction nozzle 210 is lowered, and the air core coil 810 is placed on the preposition table 310. If the placement is completed, the suction nozzle 210 releases the suction of the air core coil 810, and returns to the upper portion of the preposition part 300. At this time, the operation part 100 and the suction nozzle 210 end the operation, and thus, the operation part 100 and the air core coil 810 are transferred to the next air core coil 810 for the pickup process.

[0257] On the other hand, for example, the air core coil 810 placed on the preposition table 310 in the state shown in Figure 13A is moved to the inner side corner portion of the positioning member 320 by blowing the air streams f1, f2 as shown in Figure 13B In addition, the air streams f1, f2 can be generated, for example, via the negative pressure generation holes formed in the positioning member 320. Further, the air streams f1, f2 can also be generated by arranging a positive pressure generation nozzle upstream of the direction shown in Figure 13B Thus, with respect to the air core coil 810 whose position and posture are corrected in this way, the transport nozzle 220, which is actually the same structure as the suction nozzle 210, is lowered, and the air core coil 810 is sucked and transported to the placement part 500, which is the final transport destination of the coil transport device 10 (step S7). Figure 13C

[0258] At the time of the transport to the placement part 500 by the transport nozzle 220, the camera of the second system described above is used to perform the inspection of the air core coil 810 as a single body (inspection 1) (step S8).

[0259] In this inspection step, the air core coil 810 is photographed from a plurality of directions by a camera not shown, and, for example, it is investigated whether the size of the air core coil 810 is within a prescribed range, and whether the air core coil 810 is damaged or deformed.

[0260] Here, for example, as shown in Figure 15A and Figure 15B , the appearance dimensions such as the width D1 of the coil in one direction, the coil height D2, the lead width D3a, D3b, the width D4 of the coil in the other direction, and the height D5 of the lead terminal are inspected based on the camera photographed images.

[0261] If the air core coil 810 passes through such an inspection and is transported to the upper portion of the placement part 500, the air core coil 810 is placed at a prescribed position of the placement part 500 (step S9).

[0262] As shown in Figure 14A and Figure 14B ​As shown, the transport nozzle 220 is lowered, and the air core coil 810 is placed at a prescribed position of the placement surface 510 of the placement section 500. In the present embodiment, the placement section 500 is an adhesive sheet on which the air core coils 810 are placed in a two-dimensional arrangement, and the air core coil 810 to be newly placed is placed on the adhesive sheet as Figure 14B As shown, the distance of the placement surface 510 from the surrounding air core coils 810 is strictly controlled, and in addition, the posture of the air core coil 810 is also appropriately controlled, and placed at a desired position.

[0263] If the air core coil 810 is placed on the placement section 500, an inspection (inspection 2) of the placement state (adhesion state) and the like of the air core coil 810 on the placement section 500 is performed (step S10).

[0264] In this inspection step, the state of the upper surface of the placement surface 510 including the reference line 511 as shown, or the upper portion of the placement section 500 is imaged from substantially the same height (viewpoint) as the placement surface 510, and based on the imaged image data, the placement state of the air core coil 810 is inspected (good or bad judgment). Alternatively, in this inspection step, when the air core coil 810 is transported from the pre-setting stage 300 to the placement section 500, the image data imaged by the camera of the second system is also referred to, and the placement state of the air core coil 810 is inspected. Figure 16A Figure 16B As shown, the distance of the placement surface 510 from the surrounding air core coils 810 is strictly controlled, and in addition, the posture of the air core coil 810 is also appropriately controlled, and placed at a desired position.

[0265] Specifically, for the placement state as shown, for each air core coil 810a to 810d, whether the distance D6, D7 from the reference line 511 is appropriate, whether the distance D8, D9 from the adjacent air core coil 810 is appropriate, whether it is appropriately disposed in the prescribed region P1 to P4, or whether it is placed without inclination in the plane parallel to the adhesive surface 510, and the like related to the placement position are inspected. As a result, for example, the air core coil 810d is detected to have an abnormality in parallelism with respect to the reference line 511, or an abnormality in which it is not appropriate for the region P4, and the like, and is judged to be defective. Figure 16A In addition, for the placement state as shown, whether the height D10 from the placement surface 510 is appropriate, whether the air core coil 810 is not inclined in the height direction, whether the foot portions 813a, 813b are not floating from the placement surface 510 (not adhered to the adhesive surface 510), or whether the shape of the air core coil 810 is appropriate, and the like are inspected. As a result, for example, the air core coil 810f is judged to be defective because the height D10 is outside the prescribed range.

[0266] Figure 16B In addition, for the placement state as shown, whether the height D10 from the placement surface 510 is appropriate, whether the air core coil 810 is not inclined in the height direction, whether the foot portions 813a, 813b are not floating from the placement surface 510 (not adhered to the adhesive surface 510), or whether the shape of the air core coil 810 is appropriate, and the like are inspected. As a result, for example, the air core coil 810f is judged to be defective because the height D10 is outside the prescribed range.

[0267] ​​If the mounting condition (adhesive condition) of the air-core coil 810 is detected, the mounting condition of the air-core coil 810 with poor mounting condition is corrected (step S11). The correction of the mounting condition of the air-core coil 810 is performed by blowing air into a specified part of the air-core coil 810 using an air jet nozzle 241.

[0268] Specific examples are used to illustrate the inspection of the placement posture and shape of the air-core coil 810 in process S10, and the correction of the posture of the defective air-core coil 810 in process S11.

[0269] like Figure 25A As shown, when the foot 813a is raised, the feet 813a and 813b are sometimes placed on the adhesive surface 510 of the mounting portion 500. That is, in this embodiment, because the mounting surface 510 is adhesive, if one foot 813b is adhered to the adhesive surface 510, the air coil 810 is sometimes maintained in this posture even if the other foot 813a is raised. In this case, the air coil 810 is held in this posture. Figure 25A An improper posture, as shown, that is tilted vertically relative to the adhesive surface is placed on the adhesive surface 510.

[0270] In this embodiment, based on image data obtained from a camera or the like in a third system, the tilt angle θ1 of the upper surface 812a of the winding portion 812 of the hollow coil 810 relative to the adhesive surface 510 is detected. If the tilt angle θ1 significantly exceeds a predetermined range, it is determined that the foot 813a is not adhered and is floating. That is, it is determined that the predetermined adhesion surface when the hollow coil 810 is placed on the adhesive surface 510 of the mounting portion 500, i.e., the lower surface of the foot 813a, is not in an appropriate adhesion state (mounting state).

[0271] Based on this judgment, under the control of a control unit (not shown), the air jet nozzle 241 moves obliquely upward toward the foot 813a of the air-core coil 810, and the front end 204 is oriented at a predetermined angle α1 relative to the direction perpendicular to the adhesive surface 510, ejecting air f3 relative to the foot 813a. As a result, the force F3 exerted by the air f3 on the foot 813a, causing the foot 813a to move toward the adhesive surface 510, is as follows: Figure 25B As shown, the foot 813a is attached to the adhesive surface 510. That is, the air-core coil 810 is placed on the adhesive surface 510 in an appropriate posture.

[0272] like Figure 26A As shown, an inappropriate mounting state can also occur in a direction parallel to the winding axis of the winding portion 812 of the air-core coil 810. Figure 26AThe heel portion (connection portion with the winding portion 812) of the foot portion 813a (or the foot portion 813b) of the shown air core coil 810 is adhered to the adhesive surface 510, but the front end portion is in a state of floating from the adhesive surface 510. In this case, the air core coil 810 is also in a state of being placed on the adhesive surface 510 in an inappropriate posture with respect to the adhesive surface. Figure 26A The shown inappropriate posture of being inclined in the vertical direction with respect to the adhesive surface is placed on the adhesive surface 510.

[0273] In this case, in the coil conveying device 10, the inclination angle θ2 of the upper surface 812a of the winding portion 812 of the air core coil 810 is also detected on the basis of the image data obtained from the camera or the like of the third system, and in the case where the inclination angle θ2 greatly exceeds the prescribed range, it is determined that the front end portion of the foot portion 813a (813b) is not adhered but is floating.

[0274] Then, on the basis of this determination result, the air jet nozzle 241 is moved to a position opposite to the winding portion upper surface 812a of the winding portion 812 of the air core coil 810, that is, a position corresponding to the front end portion of the foot portion 813a, and air f4 is jetted with respect to the winding portion upper surface 812a. Thereby, a torque F4 with the heel portion (portion adhered to the adhesive surface 510) of the foot portion 813a as a fulcrum is applied with respect to the entire air core coil 810, and the front end portion of the foot portion 813a is moved in the direction of the adhesive surface 510. As a result, as shown, Figure 26B The entire surface of the surface (adhesion predetermined surface) on the lower side of the foot portion 813a (the foot portion 813b) of the air core coil 810 becomes a state of being adhered to the adhesive surface 510. That is, it becomes a state in which the air core coil 810 is placed on the adhesive surface 510 in an appropriate posture.

[0275] Figure 27 The state in which the foot portion 813a (or 813b) of the air core coil 810 is not parallel to the lower surface 812b of the winding portion 812 but is opened toward the front end side of the foot portion 813a at an angle θ3 is shown. That is, it is a state in which the shape of the air core coil 810 is inappropriate.

[0276] This state is difficult to detect only by the image of the air core coil 810 taken from the upper surface because the winding portion upper surface 812a is substantially parallel to the adhesive surface 510. However, if the image data of the air core coil 810 taken from the side surface side and the image data taken by the camera of the second system when the air core coil 810 is conveyed from the preset table 300 to the placement portion 500 are used, detection can be performed.

[0277] The air injection nozzle 241 is moved to the substantially center of the air core coil 810 with respect to the winding portion upper surface 812a of the winding portion 812 of the air core coil 810, and air f5 is injected with respect to the winding portion upper surface 812a. Thus, a downward force F5 is applied to the winding portion 812 of the air core coil 810 in a direction in which the entire winding portion 812 approaches the adhesive surface 510.

[0278] Thus, the winding portion 812 is moved in the direction of the adhesive surface 510 in a state in which the upper and lower surfaces 812a, 812b maintain a posture in which they are parallel to the adhesive surface 510, and in the foot portion 813a, the tip end portion does not move because it is in contact with the adhesive surface 510, and only the heel portion is pressed in the direction of the adhesive surface 510. As a result, as shown in FIG. 17, the entire surface of the surface (adhesion predetermined surface) on the lower side of the foot portion 813a (foot portion 813b) becomes adhered to the adhesive surface 510. That is, the shape of the air core coil 810 is appropriately corrected, and the air core coil 810 is placed on the adhesive surface 510 in an appropriate posture. Figure 26B

[0279] In addition, Figure 28 The foot portion 813a (or 813b) of the air core coil 810 is not parallel to the lower surface 812b of the winding portion 812 but narrows toward the tip end side of the foot portion 813a at an angle θ4. This state is also a state in which the shape of the air core coil 810 is not appropriate.

[0280] This state is also a state in which the winding portion upper surface 812a is substantially parallel to the adhesive surface 510, and thus it is difficult to detect only from an image of the air core coil 810 taken from the upper surface, but if image data of the air core coil 810 taken from the side surface side and image data taken by the camera of the second system are used, detection is possible.

[0281] With respect to the air core coil 810, the air injection nozzle 241 is inclined at a prescribed angle α2 with respect to a direction perpendicular to the adhesive surface 510 toward the tip end portion of the foot portion 813a of the air core coil 810, and air f6 is injected with respect to the space between the foot portion 813a and the winding portion lower surface 812b.

[0282] As a result, a force F6 that moves the tip end portion in the direction of the adhesive surface 510 is applied to the foot portion 813a by the air f6. In addition, a force that moves the winding portion 812 in the upward direction is applied to the winding portion 812 by the air f6 that enters the recess between the winding portion lower surface 812b and the foot portion 813a (813b). At this time, because the heel portion of the winding portion 812 and the foot portion 813a (812b) do not move because they are adhered to the adhesive surface 510 by the foot portions 813a, 813b, a force F7 that moves the portion of the winding portion 812 opposite the tip end side of the foot portion 813a in the upward direction is applied to the portion.​

[0283] As a result, as shown in Figure 26B , the leg portion 813a becomes a state of being stuck to the sticking surface 510. In addition, the winding portion 812 becomes a state in which the portion corresponding to the front end side of the leg portion 813a is slightly moved upward, and the state in which the lower surface 812b of the winding portion 812 and the front end portion of the leg portion 813a are narrowed is corrected. That is, while the shape of the air core coil 810 is appropriately corrected, the defect of the shape of the air core coil 810 is corrected.

[0284] With respect to the air core coil 810 determined to be in the placement state defect in the inspection 2 process (refer to Figure 6 ), the process of achieving correction of such a placement state or correction of the shape in the placement state correction process S11 is applied. On the other hand, for the air core coil 810 determined to be defective as a result of the inspection, a process of marking the defective product or the like is performed, and a process of not being mixed with good products in the next process is performed. Furthermore, a mechanism and a control portion that re-adsorb and re-arrange the air core coil 810 determined to be defective can also be provided.

[0285] The coil conveying device 10 performs the above process and performs the extraction and conveyance of the air core coil 810.

[0286] With respect to the electronic component manufacturing method and the manufacturing device of the present application, a process of further manufacturing the coil component 900 shown in Figure 24 using the air core coil 810 conveyed by the coil conveying device 10 as described above is described.

[0287] The air core coil 810 placed on the placement portion 500 is supplied to an outer seal process as the next process. In the outer seal process, for example, a mold frame is formed in a manner of surrounding the periphery of the plurality of air core coils 810 placed on the sticking surface 510 with respect to the sticking sheet 500 as the placement portion, resin is injected into the mold frame and cured to be singulated. At this time, as necessary, plating film can also be formed on the exposed surface of the leg portions 813a and 813b. As a result, as shown in Figure 24 , an electronic component in which the air core coil (coil portion) 810 as an electronic element is sealed and housed inside the base body 910, that is, the coil component 900 in which the air core coil is embedded in the base body 910 is manufactured.

[0288] In addition, according to the coil conveying device 10 of the present embodiment, for example, even in the case of a component such as the air core coil 810 arranged around the core rod 710 in the supply source of the manufacturing device or the carrying-in device, and the like, a small and weak mechanical strength component, appropriate extraction and conveyance can be achieved without being damaged, falling, or the like.

[0289] When the air core coil 810 is pulled out by contact by the operation section 100 alone, the air core coil 810 can fall. Also, when the air core coil 810 is held by suction by the suction nozzle alone, air leaks from the steps or irregularities of the peripheral surface of the air core coil 810 and suction cannot be performed sufficiently, and the air core coil 810 can fall. However, in the coil conveying device 10 of the present application, since the air core coil 810 is sucked by the suction nozzle 210 and the contact surfaces 142, 142 of the operation section 100 are brought into contact with the air core coil 810 to perform pulling out and holding, falling can be prevented.

[0290] Also, according to the coil conveying device 10, the air core coil 810 can be moved to the open end side of the bobbin 710 and pulled out without being held by the operation section 100. That is, by combining the suction nozzle 210 and the operation section 100, the air core coil 810 is supported by the operation section 100 and is sucked by the suction nozzle 210, and the air core coil 810 is extracted. As a result, according to the coil conveying device 10, the air core coil 810 can be extracted and conveyed appropriately and stably without damaging the air core coil 810.

[0291] Also, according to the coil conveying device of this configuration and method, by blowing air ejected from the air ejection nozzle 241 to a prescribed portion of the member, a force is applied to a prescribed portion of the air core coil 810 or to the air core coil 810 noncontactingly. Therefore, compared to a case where a force is applied by mechanical contact with the air core coil 810, a force can be applied to a prescribed portion such as the leg portions 813a, 813b of the air core coil 810 extremely weakly, and the placement state or shape of the air core coil 810 can be corrected. As a result, the air core coil 810 is not easily damaged by overloading, and the placement state or shape of the air core coil 810 can be corrected with high precision.

[0292] The coil conveying device 10 of the present embodiment is particularly effective when the air core coil 810 is small. That is, the coil conveying device 10 of the present embodiment can set a member having a prescribed surface (for example, a leg portion) to a desired placement state (stuck state) with high precision since a force is applied to the member by a noncontact means such as an air current, and the air core coil 810 is not easily damaged even when the air core coil 810 is small and has low mechanical strength.

[0293] Further, according to the coil conveying device 10 of the present embodiment, since the force is applied to the prescribed portion of the air core coil 810 or to the air core coil 810 noncontactingly, a structure such as a portion of a tool or a device does not mechanically contact the air core coil 810. As a result, the surface or the like of the air core coil 810 is not easily damaged. That is, with respect to the wire wound to form the air core coil 810, it is possible to suppress damage to the coating film thereof. Therefore, from this point of view as well, it is possible to appropriately apply the force to the air core coil 810, and to set the air core coil 810 having the predetermined surfaces (the leg portions 813a, 813b) adhered to the desired placement state (adhered state).

[0294] Further, the present application is not limited to the above-described embodiments, and various modifications can be made as exemplified below.

[0295] In the above-described embodiments, when the air core coil 810 provided to the mandrel 710 is taken out, first, the suction nozzle 210 is suctioned to the air core coil 810, and then the contact surfaces 142, 142 of the columnar portions 101a, 101b of the operation portion 100 are brought into contact with the air core coil 810, and the air core coil 810 is pulled out from the mandrel 710. However, the suction by the suction nozzle 210 and the contact by the operation portion 100 are not limited to this order. From the viewpoint of the efficiency of the taking-out of the component (the air core coil 810) or the safety at the time of taking-out, the timing of the movement of the columnar portions 101a, 101b, the movement of the suction nozzle 210, and the operation of the suction (suctioning) by the suction nozzle 210, and the like can be arbitrarily and appropriately set.

[0296] That is, the suction and the contact can be performed substantially simultaneously, or the order in which the contact surfaces 142, 142 of the operation portion 100 are brought into contact with the air core coil 810 first, and then the suction by the suction nozzle 210 is performed. Alternatively, it is also possible to have a structure in which the operation of the front end portion 204 of the suction nozzle 210 abutting against the peripheral surface of the air core coil 810 is performed prior to the contact of the operation portion 100 to the air core coil 810, and the suction by the suction nozzle 210 is performed substantially simultaneously with the contact of the operation portion 100 to the air core coil 810 or during the period in which the air core coil 810 is moved upward by the operation portion 100. In order to perform the taking-out and the conveying of the air core coil 810 by the same effects as those of the above-described embodiments, it is sufficient that both the contact by the operation portion 100 and the suction by the suction nozzle 210 are completed before (at the time of) the air core coil 810 is pulled out from the mandrel 710.

[0297] In addition, the method of applying a force in the direction of the adhesive surface 510 to the leg portions 813a (813b) and the winding portion 812 of the air core coil 810 (i.e., the method of noncontact application of a force to a prescribed portion of a member) is not limited to the application of air through the air injection nozzle 241. For example, a plurality of fine holes can be formed in a placement surface (e.g., the placement 500 including the adhesive surface 510) on which the member is placed, and the gas (air or the like) around the air core coil 810 placed thereon can be suctioned through the holes, thereby applying a noncontact force (suction force) in the direction of the placement surface to the leg portions 813a (813b) and the like of the air core coil 810.

[0298] Alternatively, a magnetic field or the like can be formed in the space on which the air core coil 810 is placed, and a noncontact force in the direction of the placement surface (adhesive surface) 510 can be applied to the winding portion 812 of the air core coil 810, the leg portions 813a (813b) of the air core coil 810, or the entire air core coil 810 by magnetic force in a manner in which the winding portion 812 of the air core coil 810, the leg portions 813a (813b) of the air core coil 810, or the entire air core coil 810 is subjected to a magnetic force. Alternatively, an electric field or the like can be formed in the space on which the air core coil 810 is placed, and a noncontact force in the direction of the placement surface (adhesive surface) 510 can be applied to the winding portion 812 of the air core coil 810, the leg portions 813a (813b) of the air core coil 810, or the entire air core coil 810 by electrostatic force in a manner in which the winding portion 812 of the air core coil 810, the leg portions 813a (813b) of the air core coil 810, or the entire air core coil 810 is subjected to an electrostatic force. The method to be appropriately applied can be selected depending on the material (e.g., a conductor or a dielectric) of the portion to be subjected to the force.

[0299] In addition, the air core coil 810 pulled out from the mandrel 710 can be directly transported to the placement 500 without being placed on the pre-placement 300. In a case in which the suction force of the suction nozzle 210 is sufficient and the air core coil 810 suctioned by the suction nozzle 210 has sufficient positional accuracy and does not require high-accuracy positioning, the air core coil 810 can be directly transported to the placement 500 without being placed on the pre-placement 300. If this structure is employed, the pre-placement and resuction process is not required, and the transport efficiency of the member can be improved and the transport process can be simplified. In addition, since the transport nozzle 220 is not required, the structure of the coil transport device 10 can be simplified.

[0300] At this time, the point at which the contact surfaces 142, 142 of the operation portion 100 support the air core coil 810 and the point at which the suction nozzle 210 is rotated to place the air core coil 810 in a posture in which the air core coil 810 can be placed on the placement 500 can be arbitrarily configured.

[0301] When the hollow coil 810 is pulled out from the mandrel 710 by the operating part 100 and the adsorption nozzle 210, the operating part 100 supports the hollow coil 810 in the vertical direction through the contact surfaces 142, 142. Therefore, from the point of view of safely transporting the hollow coil 810, it is preferable to transport the hollow coil 810 to the upper part of the mounting part 500 in a state and posture where both the support provided by the operating part 100 and the adsorption provided by the adsorption nozzle 210 are engaged, at least the adsorption nozzle 210 rotates in the upper part of the mounting part 500 and positions the hollow coil 810 in a posture that can be placed in the mounting part 500.

[0302] However, if the adsorption force of the adsorption nozzle 210 is sufficient, the pair of columnar portions 101a and 101b can be opened immediately when the hollow coil 810 is pulled out from the mandrel 710, thus releasing the support of the hollow coil 810 provided by the operation unit 100. If this structure is adopted, the operation unit 100 can be used for the next process.

[0303] Furthermore, when the support for the hollow coil 810 is released from the operating unit 100 in the early stage, the point at which the adsorption nozzle 210 is rotated can be arbitrarily determined, based on the point of continuing to stably adsorb the hollow coil 810 while overcoming the resistance received from gravity or the transport direction, or the point of efficiency in placing the hollow coil 810 on the mounting unit 500 in a short time. Rotation can be performed at the moment the support for the operating unit 100 is released, or at the top of the mounting unit 500 just before the hollow coil 810 is placed, or even while moving from the point where the hollow coil 810 is pulled out to the mounting unit 500.

[0304] Furthermore, in the above-described embodiment, a two-stage inspection process using a camera is included, but the determination of good / defective products is performed through other processes or other devices. The coil conveying device 10 can also be configured to simply remove and convey the air-core coil 810 from the core rod 710. That is, it is also possible to omit the inspection process, and this approach is also within the scope of the present invention.

[0305] Furthermore, the supply method of the air coil 810 is not limited to the case of taking out and transporting the air coil 810 wound on a single core rod 710.

[0306] For example, such as Figure 17A As shown, sometimes protrusions 723 are provided on the upper surface of multiple base pillars 722, and air-core coils 810 are wound sequentially on them for supply. Additionally, as... Figure 17BAs shown, sometimes multiple protrusions 733 are provided on the surface of the substrate 731, which serves as the base, and air-core coils 810 are sequentially wound on them for supply. In any of these cases, the air-core coils 810 can be taken out and transported in the same order as described above using the coil transport device 10.

[0307] In addition, for example, Figure 18A As shown, sometimes multiple posts 741 protrude horizontally from the vertical wall 741, and protrusions 743 are formed on the end face of the vertical wall 741, on which air-core coils 810 are sequentially wound for supply. For this method, as... Figure 18B As shown, the air coil 810 can be pulled out by simply arranging the operating part 100 with the opposite surfaces of the pair of columnar parts 101a and 101b in a vertical direction and pulling the operating part 100 in a horizontal direction.

[0308] In this case, the contact surfaces 142, 142 of the pair of columnar portions 101a, 101b will not support the hollow coil 810 along the direction of gravity. Therefore, the hollow coil 810 needs to be held in place by the suction force of the suction nozzle 210. However, since one of the opposing surfaces 152, 152 is located close to the lower side of the hollow coil 810, even if the suction force of the suction nozzle 210 is weakened, it is possible to prevent the component from remaining on the opposing surface 152 and falling downwards. Therefore, this method can also prevent damage.

[0309] In addition, Figure 18B In this configuration, the pair of columnar portions 101a and 101b of the operating section 100 are arranged in a pair in the Z direction, but the columnar portions 101a and 101b can also be arranged in a pair in the Y direction. In this case, the adsorption nozzle is arranged towards the air coil 810 from the upper side or the lower side in the Z direction.

[0310] Furthermore, in the above embodiment, the pair of columnar portions 101a and 101b of the operation unit 100, such as Figure 1 As shown, an example is illustrated where a contact surface 142 and a widened portion 143 are formed on the stepped surface 141. Additionally, a pair of columnar portions 101a and 101b are formed on the inner surface 151 of the columnar portion, consisting of a component-facing surface 152 and an inner surface widened portion 153. However, the structure of the columnar portion of the operating part 100 is not limited to this structure; the structure of the columnar portion of the operating part 100 could also be, for example, [other configurations]. Figures 19-20B The structure shown.

[0311] exist Figures 19-20B In the pair of columnar portions 171a and 171b shown, a protrusion 180 is formed at the front end 174, and a stepped surface 182 is formed on the inner side 192 of the columnar portion body 173. Figure 1 The method shown is the same. However, inFigure 19 In the columnar portions 171a, 171b shown, the entire region of the step surface 182 is formed on the contact surface, and there is no portion like the widened portion 143. Also, the entire region of the inner surface 192 is formed on the opposite surface 192, and it is not a structure like the widened portion 153. The pair of columnar portions of the operation portion can also be configured in this shape. If configured in this structure, processing becomes easy, and the operation portion 100 can be manufactured inexpensively.

[0312] Also, in the above-described embodiment, the manner of taking out and conveying the air core coil 810 in which round wire is wound was described, but the coil conveying device 10 can also be applied to other coils.

[0313] For example, as shown in Figs. 23A and 23B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 21A Figure 21B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 21A Figure 21B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 21A Figure 21B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape.

[0314] As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 22A Figure 22B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 22A Figure 22B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 21A Figure 21B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 22A Figure 22B As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape.

[0315] As shown in Figs. 24A and 24B, the coil conveying device 10 can also be applied to the taking out and conveying of a pancake coil 820 in which flat wire 821 is wound in a pancake shape. Figure 23A Figure 23B ​​​​​​​​As shown, the coil conveying device 10 can also be applied to the extraction and conveyance of the cross-width-adjusted coil 840 to which the flat wire 841 is double-spindle wound. In the cross-width-adjusted coil 840, a flat surface is formed on the main surface, and thus, as in the above-described embodiment, it is effective to cause the suction nozzle 210 to adhere to the circumferential surface of the cross-width-adjusted coil 840 from the horizontal direction.

[0316] Thus, the coil conveying device 10 of the present application can be applied to various coils.
