Description

Technical Field

[0001] The present invention relates to a part feeder used on a feeder base provided in a component assembly apparatus, and a component assembly apparatus having the part feeder. Background Technology

[0002] Conventionally, a part feeder that supplies parts to a part assembly device has a socket insertion portion at the lower part of the main body, which includes a part supply mechanism. This socket insertion portion is inserted into a socket groove formed in a feeder base to assemble the part feeder base. The part feeder assembled in the feeder base is clamped by a clamping mechanism and fixed relative to the feeder base. On the other hand, when the clamped part feeder is removed from the feeder base, a rod-shaped operating member provided in the main body is operated in the vertical direction (for example, see Patent Document 1 below).

[0005] Patent Document 1: Japanese Patent Application Publication No. 2014-3160 Summary of the Invention

[0006] However, in the past, when removing a part feeder from its base, the operator needed to perform both vertical manipulation of the control component and horizontal pulling of the part feeder from the base, resulting in low efficiency. Furthermore, in recent years, research has focused on using robots to remove the part feeder from its base to reduce manpower. However, in this case, the robot needs not only a horizontal axis to move the part feeder but also a vertical axis to manipulate the aforementioned rod-shaped control component. This complicates the robot's structure and operation, potentially increasing costs.

[0007] Therefore, the object of the present invention is to provide a part feeder and a component assembly apparatus that enable the part feeder to be removed from the feeder base with simple operation.

[0008] The part feeder of the present invention is used by mounting it on a feeder base provided in a component assembly apparatus. The part feeder includes: a main body having a part supply mechanism for supplying parts to a part removal position of an assembly head provided in the component assembly apparatus, and being clamped to the feeder base in a removable state; and a clamping release mechanism having a release operation part operated by an operator to set the main body in a state where it can be removed from the feeder base. The release operation part includes: a sliding part that slides relative to the main body; and a swinging part that swings the base to the sliding part, and by swinging, can achieve an upright posture with the front end close to the main body and a horizontal posture with the front end away from the main body.

[0009] The component assembly apparatus of the present invention includes: the component feeder of the present invention described above; and an assembly head that uses a nozzle to adsorb and assemble components supplied by the component feeder onto a substrate.

[0010] According to the present invention, the part feeder can be removed from the feeder base with simple operation. Attached Figure Description

[0185] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 as well as Figure 2A side view and a top view of the main parts of a component assembly apparatus 1 according to an embodiment of the present invention are shown respectively. The component assembly apparatus 1 is an apparatus that repeatedly performs component assembly operations by assembling a substrate KB into a component BH from an upstream process side and moving it out to a downstream process side. For ease of explanation, the direction of transporting the substrate KB into and out of the component assembly apparatus 1 will be described here. Figure 1 The middle direction is perpendicular to the paper surface. Figure 2 The horizontal direction (left and right on the paper) is defined as the X direction, the horizontal direction orthogonal to the X direction is defined as the Y direction, and the vertical direction is defined as the Z direction. In addition, when viewed from the operator's perspective, the X direction is defined as the left and right direction, the Y direction is defined as the front and back direction, the side away from the operator's perspective is described as "front", and the side closer to the operator's perspective is described as "back".

[0186] exist Figure 1 In this assembly, the component assembly apparatus 1 includes a base 11, a substrate transport path 12, a component feeder 13, an assembly head 14, a head movement mechanism 15, a component identification camera 16, and a control device 17. The substrate transport path 12 includes a pair of belt conveyors 12a, which extend along the X-direction on the base 11. The substrate transport path 12 picks up substrates KB from the upstream process side and positions them at a predetermined working position.

[0187] exist Figure 1 In this embodiment, a feeder trolley 21 is connected to the front (rear) side of the base 11 as observed by the operator (OP). A feeder base 22 is provided on the upper part of the feeder trolley 21, and the part feeder 13 is detachably mounted on the feeder base 22. In this embodiment, the part feeder 13 includes a belt feeder, from which a carrier belt CT containing the part BH is pulled out from a reel RL held on the feeder trolley 21, and moved to the part removal position 13K set at the front of the part feeder 13 (see also...). Figure 2 Supply component BH.

[0188] exist Figure 2 In this configuration, multiple part feeders 13 can be arranged and mounted along the X direction on the feeder base 22. When the feeder trolley 21 is connected to the base 11, the multiple part feeders 13 mounted on the feeder base 22 are connected to the base 11 together.

[0189] exist Figure 1 In this assembly head 14, multiple nozzles 14N extend downwards. Each nozzle 14N is capable of lifting and rotating about an axis along the Z direction (Z-axis), and is supplied with vacuum pressure from a vacuum source (not shown), thereby generating an adsorption force at its lower end. Figure 2As shown, the head moving mechanism 15 includes two Y-platforms 15y extending in the Y direction and arranged in the X direction, and an X-platform 15x extending in the X direction and supported at both ends by the two Y-platforms 15y.

[0190] exist Figure 2 In this configuration, assembly head 14 is mounted on X-stage 15x. Assembly head 14 is driven to move in the X direction by a drive mechanism (e.g., a linear motor) disposed between it and X-stage 15x. X-stage 15x is driven to move in the Y direction by a drive mechanism (e.g., a linear motor) disposed between it and two Y-stages 15y. Assembly head 14 moves in the horizontal plane (XY plane) above base 11 by the movement of assembly head 14 relative to X-stage 15x in the X direction and the movement of X-stage 15x relative to Y-stages 15y in the Y direction.

[0191] exist Figure 1 as well as Figure 2 In the center, the component identification camera 16 is positioned in the area between the substrate transport path 12 and the feeder trolley 21 on the base 11. The component identification camera 16 has its shooting optical axis pointing upwards. The component identification camera 16 captures images of each component BH as the assembly head 14, which has been adsorbed by the nozzle 14N, passes overhead.

[0192] The control device 17 controls the operation of each part constituting the component assembly device 1. Specifically, the control device 17 controls the transport operation of the substrate KB performed by the substrate transport path 12 and the positioning operation to the working position, and controls the supply operation of the component BH performed by each component feeder 13.

[0193] The control device 17 controls the lifting and rotating movements of each of the multiple nozzles 14N on the assembly head 14, and controls the suction force generated at the lower end of each nozzle 14N to attract the component BH. Additionally, the control device 17 controls the movement of the assembly head 14 by activating the head moving mechanism 15. The control device 17 also controls the capturing action of the component recognition camera 16. Figure 1 As shown, the control device 17 is connected to the work instruction unit SSB of the unified control component assembly production line included in the component assembly device 1, and receives work instructions and production procedures required for the operation of the component assembly device 1 from the work instruction unit SSB.

[0194] When component assembly is performed in component assembly apparatus 1, the substrate KB from the upstream process side is first received by substrate transport path 12 and positioned in the work position. After the substrate KB is positioned in substrate transport path 12, head moving mechanism 15 operates to move assembly head 14 above part feeder 13, and assembly head 14 uses multiple nozzles 14N to pick up component BH. Assembly head 14, with component BH picked up by nozzles 14N, moves in a manner that passes above component recognition camera 16, and component recognition camera 16 identifies the component BH passing above.

[0195] After the component recognition camera 16 recognizes component BH, the head moving mechanism 15 moves the assembly head 14 upwards towards the substrate KB, assembling component BH at the target assembly coordinates set on the substrate KB. By repeating this series of assembly cycles, including the adsorption, recognition, and assembly of component BH, after all components BH to be assembled on the substrate KB have been assembled, the substrate transport path 12 operates to move the substrate KB to the downstream process side. This completes the component assembly operation for one substrate KB.

[0196] In this component assembly apparatus 1, the component feeder 13 in this embodiment has a distinctive structure, which will be described below. First, the structure of the feeder base 22 for mounting the component feeder 13 will be described.

[0197] Figure 4 This is a perspective view of the feeder base 22 included in the component assembly apparatus 1 according to an embodiment of the present invention. Figure 2 In this configuration, the feeder base 22 is composed of a plate-like component that is integrally formed into a rectangular shape. For example... Figure 2 as well as Figure 4 As shown, a plurality of slot forming members 23 are arranged at intervals along the X direction on the upper surface of the feeder base 22. These slot forming members 23 form slots 23S for assembling the part feeder 13 into the feeder base 22.

[0198] As described later, the part feeder 13 is selectively inserted into one of the plurality of socket slots 23S for installation. At this time, the part feeder 13 is positioned at the front of the socket slot 23S as viewed from the operator's (OP) side. Figure 2 (below the paper surface) towards the depth side ( Figure 2 It slides into place (above the paper). Hereinafter, this sliding direction will be referred to as the assembly direction. Figure 2 as well as Figure 4 The arrow At shown. Additionally, the direction opposite to the assembly direction is called the disengagement direction (in...). Figure 2 as well as Figure 4The arrow Re is indicated by a dashed line. When removing the part feeder 13 from the slot 23S, the part feeder 13 is slid in the disengagement direction.

[0199] Figure 5 This is a side view of the feeder base 22 included in the component assembly apparatus 1 according to an embodiment of the present invention. Figure 2 , Figure 4 as well as Figure 5 In the feeder base 22, a feeder limiter 24 is provided at the end of the feeder base 22 on the depth side to position the part feeder 13 inserted into the socket slot 23S. The feeder limiter 24 is provided with an upper pin insertion hole 24A and a lower pin insertion hole 24B respectively in the upper and lower parts, corresponding to each socket slot 23S.

[0200] exist Figure 4 as well as Figure 5 In this device, a bracket 25 extending rearward and downward from the lower rear surface of the feeder base 22 is provided. The bracket 25 is composed of a first member 25A mounted on the lower surface of the feeder base 22 and a second member 25B mounted on the lower surface of the first member 25A. The first member 25A extends rearward and has a plug 26 on its rear end face arranged in a configuration corresponding to each socket slot 23S. The plug 26 is one component constituting a connector for electrical wiring. The plug 26 is positioned to protrude rearward.

[0201] exist Figure 4 as well as Figure 5 In this design, the second component 25B extends rearward, and its rear end has an L-shaped cross-section that bends downward. Furthermore, a locking pin 27 is provided on the downward-bent portion, corresponding to each socket slot 23S. The locking pin 27, like the plug 26, is also positioned to protrude rearward.

[0202] exist Figure 4 In the feeder base 22, a plurality of support portions 22B are provided at intervals along the X direction at the rear end. The plurality of support portions 22B are arranged such that the space between adjacent support portions 22B lies on the extension line of the insertion slot 23S. A clamping mechanism 31 (see also [reference]) is provided in the space between adjacent support portions 22B in a configuration corresponding to each insertion slot 23S. Figure 2 ).

[0203] like Figure 4 as well as Figure 5 As shown, the clamping mechanism 31 includes an arm 32 that extends integrally along the Y direction. The two ends of the support shaft 22J are supported at two adjacent support portions 22B. Figure 4 as well as Figure 5The support shaft 22J extends through the middle part of the arm 32 along the X direction. Therefore, the arm 32 can swing freely about the support shaft 22J in the space between two adjacent support parts 22B.

[0204] There are two arms 32 arranged in a pair along the X direction. Figure 6A as well as Figure 6B This is a side view of the clamping mechanism 31 provided in the feeder base 22 of the component assembly apparatus 1 according to an embodiment of the present invention. Figure 5 , Figure 6A as well as Figure 6B In the middle, the rear ends of the two arms 32 are connected by an operating part 33 extending in the X direction, and the middle parts of the two arms 32 are connected by a fixing part 34 extending in the X direction. The front parts of the two arms 32 are connected by a receiving part 35.

[0205] exist Figure 5 , Figure 6A as well as Figure 6B In this configuration, the fixing element 34 is located on the arm 32 at a position separated rearward from the support shaft 22J, and the operated part 33 is located at a position further rearward from the fixing element 34. That is, the operated part 33 is located further away from the support shaft 22J than the fixing element 34. Both the fixing element 34 and the operated part 33 are constructed from a smooth-surfaced pin or a roller (bearing) capable of rotating about an axis along the X direction.

[0206] exist Figure 5 , Figure 6A as well as Figure 6B In the bracket 25, a force-applying spring 36 is fitted to the first component 25A. The force-applying spring 36 applies an upward force to the receiving portion 35 of the arm 32. When the part feeder 13 is not inserted into the insertion slot 23S, the arm 32, under the action of the force-applying spring 36, is stationary at the position where the receiving portion 35 abuts against the lower surface of the feeder base 22. Figure 6A On the other hand, when from Figure 6A When the pushing force is applied to the operated part 33 at the rear end of the arm 32, the arm 32 swings around the support shaft 22J against the force of the applied spring 36. Figure 6B As shown by arrow M), it becomes a state that swings in the direction of pushing towards the rear end. Figure 6B ).

[0207] Thus, in this embodiment, the clamping mechanism 31 is structured such that it has an assembly direction relative to the part feeder 13 ( Figure 4 The axis (support shaft 22J) that is horizontally crossed by the arrow At shown in the figure swings around the axis, and from the disengagement direction that is opposite to the assembly direction of the part feeder 13. Figure 4The arm 32, which extends from the arrow Re shown in the diagram, has a retainer 34 at a position where it is separated from the shaft in the disengagement direction, and an operated part 33, which serves as a cam follower, at a position where it is separated from the retainer 34 in the disengagement direction (rearward). The operated part 33 is installed at a position where it is at a greater distance from the support shaft 22J, which serves as the swing fulcrum of the clamping mechanism 31, than from the retainer 34.

[0208] Next, the structure of the parts feeder will be explained. Figure 3 This is a perspective view of a part feeder included in a part assembly apparatus 1 according to an embodiment of the present invention. Figure 7A This is a side view of a parts feeder 13 according to an embodiment of the present invention. Figure 7B This is a bottom view of a parts feeder 13 according to an embodiment of the present invention.

[0209] exist Figure 3 , Figure 7A as well as Figure 7B In this part feeder 13, there is a main body 41 that extends along the YZ plane as a whole.

Figure 14 , Figure 17 as well as Figure 18 In this design, a storage portion 101 is provided at the rear of the handle portion 51, opening towards the rear surface 41b. The storage portion 101 is formed by an area surrounded by a forward-recessed portion of the rear surface 41b of the handle portion 51 and left and right covers (left cover 41L and right cover 41R). Figure 18 ).

[0243] exist Figure 17 as well as Figure 18 The storage unit 101 includes a limiting portion 102, which includes a forward-recessed portion of the rear surface 41b of the handle portion 51. The limiting portion 102 has an upper inclined portion 102a extending obliquely downward and forward, a lower inclined portion 102b extending obliquely downward and rearward from the lower end of the upper inclined portion 102a, and a horizontal portion 102c extending rearward from the lower end of the lower inclined portion 102b and connected to the rear surface of the handle portion 51. A first recess 102d is formed at the boundary between the upper inclined portion 102a and the lower inclined portion 102b, and a second recess 102e is formed at the boundary between the lower inclined portion 102b and the horizontal portion 102c.

[0244] exist Figure 18 In the middle, a sliding passage 103 with an opening in the storage section 101 and extending in the Y direction is provided at the rear of the handle section 51. This sliding passage 103 communicates with a window section 104 that opens on the right side of the main body section 41 (including the right cover 41R) and extends in the Y direction (see also...). Figure 13 , Figure 14 , Figure 15A as well as Figure 15B ).

[0245] Figure 19A as well as Figure 19B This is a partial cross-sectional top view of the release operation section 85 provided in the part feeder 13 according to an embodiment of the present invention. Figure 18 , Figure 19A as well as Figure 19B As shown, a front wall 103W is formed at the foremost part of the sliding passage 103, and a wire hole 103D is provided in the front wall 103W to pass through the front wall 103W along the thickness direction (Y direction).

[0246] The sliding part 91 is disposed within the sliding passage 103 and moves freely in the Y direction within the main body 41. When the sliding part 91 moves in the Y direction within the sliding passage 103, the limiter part 91S moves in the Y direction within the window 104. The release operation part 85 can be positioned at a first position, which is a position in which the base 92K of the swing part 92 abuts against the limiting part 102 (specifically the upper inclined part 102a and the lower inclined part 102b) of the storage part 101 from the rear. Figure 13 as well as Figure 19A ) and the second position, which is the position where the limiter part 91S abuts against the rear edge of the window part 104, i.e., the wall part 104T, from the front. Figure 14 as well as Figure 19B Move (slide) between )

[0247] When the operating part 85 is released from its first position, the swing part 92 can be positioned so that the operating end 92S is positioned above and close to the main body 41 in an upright posture. Figure 13 ) and the horizontal posture extending roughly horizontally backward and away from the main body 41 ( Figure 14 Move (swing) between these two positions.

[0248] When the swinging part 92 is operated from a horizontal position to an upright position ( Figure 14 → Figure 13 , Figure 15B → Figure 15A The right-side protrusion 94R is embedded in the second recess 102e of the limiting portion 102. Figure 13 Therefore, the swing part 92 is positioned in an upright posture and maintains the upright posture as long as it is not operated by the operator.

[0249] When the swinging part 92 is in an upright position and stored in the storage part 101, the claw part 92T, which is part of the operating side end 92S, protrudes behind the handle part 51. Figure 13 Therefore, the operator can easily set the swing part 92 to a horizontal position by pinching the claw 92T of the swing part 92 which is in an upright position and stored in the storage part 101, or by hooking the finger on the claw 92T and pulling it backward.

[0250] Thus, in this embodiment, the structure is as follows: the main body 41 is provided with a storage part 101 for storing the swing part 92 in an upright position; in addition, the operating end 92S of the swing part 92 has a claw part 92T that protrudes even when the swing part 92 is in an upright position and is not stored in the storage part 101.

[0251] When the swinging part 92 is in a horizontal position, the right protrusion 94R of the swinging part 92 is embedded in the first recess 102d of the limiting part 102. Figure 14 Therefore, the swinging part 92 is positioned in a horizontal position and maintains this horizontal position as long as it is not operated by the operator.

[0252] Thus, the external shape of the portion of the base 92K of the swing portion 92 that contacts the limiting portion 102 (specifically the first recess 102d and the second recess 102e) is such that the swing portion 92 maintains the upright posture when it is in the upright posture, and maintains the horizontal posture when it is in the horizontal posture.

[0253] A swing limiter 91T is formed at the rear of the sliding part 91. Figure 15A as well as Figure 15BThe left-side protrusion 94L formed on the base 92K of the swing portion 92 abuts against the swing portion limiter 91T from below. Therefore, even when the sliding portion 91 moves to the second position, the swing portion 92 will not swing downwards beyond the sideways posture. That is, the swing portion limiter 91T functions as a swing limiter that restricts the swing portion 92 from swinging from the upright posture to the sideways posture.

[0254] The swinging part 92 can be set to an upright posture or a horizontal posture when the release operation part 85 is in the first position. Figure 13 → Figure 14 , Figure 15A → Figure 15B By pulling the swinging part 92, which is set to a horizontal position, backward, the release operation part 85 can be positioned in the second position. Figure 14 → Figure 20 ). Figure 20 This is a side view of the rear portion of the part feeder 13 according to an embodiment of the present invention. Even when the release operation part 85 is in the second position, the left protrusion 94L remains in contact with the swing part limiter 91T, so the swing part 92 remains in a horizontal position even when it is pulled out toward the rear of the handle part 51 together with the sliding part 91 (and does not become a position where the operation side end 92S hangs down).

[0255] exist Figure 13 , Figure 14 , Figure 15A as well as Figure 15B In the middle, a wire retainer 111 is mounted on the right surface of the sliding part 91. For example... Figure 16 As shown, the wire retainer 111 has a main portion 111a that extends along the YZ plane and along the Y direction, and an extension portion 111b that bends to the left and extends from the rear end of the main portion 111a. Two nuts 111N arranged along the Y direction are provided in the main portion 111a, and a slit portion 111S extending along the Y direction is provided in the extension portion 111b.

[0256] exist Figure 15A , Figure 15B as well as Figure 16 In the sliding part 91, the wire retainer 111 is mounted on the right surface of the sliding part 91 by two bolts 112 arranged along the Y direction. The wire retainer 111 is provided with two elongated holes 91H extending along the Y direction and arranged along the Y direction.

[0257] Two bolts 112 pass through the elongated hole 91H and are screwed into the nut 111N, tightening the bolts 112 relative to the nut 111N, thereby fixing the wire retainer 111 to the sliding part 91. Therefore, by temporarily loosening the bolts 112 tightened relative to the nut 111N and moving the wire retainer 111 relative to the sliding part 91 in the Y direction, and then tightening the bolts 112 again, the mounting position of the wire retainer 111 relative to the sliding part 91 can be arbitrarily changed within the length of the elongated hole 91H in the Y direction.

[0258] exist Figure 7A as well as Figure 8 In this configuration, line 86 extends vertically within the main body 41. The upper end of line 86 is mounted to the front end of line holder 111, and the lower end of line 86 is mounted to rod 84. In other words, line 86 serves as a component that connects the release operation part 85 to rod 84.

[0259] Here, the upper end of the wire 86 passes through the sliding passage 103 and the aforementioned wire hole 103D provided on the front wall 103W.

The lower end of the wire 86 is mounted on the rear end of the rod portion 84.

[0260] exist Figure 8 as well as Figure 10 In the middle, the portion of the upper end side of line 86 that extends forward from the sliding part 91 is formed within the main body 41 by an arc-shaped guide surface 41M. Figure 17 The line 86 extends forward from the upper end to the guide surface 41M, and bends downward at the guide surface 41M and extends downward (towards the rod 84).

[0261] As described above, the lever 84 abuts against the roller 82R at the rear end of the clamping release member 82, which is subjected to force in the downward direction of the return spring 83, and receives the upward force from the return spring 83 via the clamping release member 82. Furthermore, the length of the line 86 is adjusted such that it is fully extended (tense) when the release operation part 85 is in the first position.

[0262] That is, in this embodiment, the clamping release mechanism 80 is structured such that the return spring 83, which is an elastic body that applies force to the release operation part 85 in the direction of pulling it toward the interior of the main body part 41, and the main body part 41 is provided with a limiting part 102 that restricts the movement of the release operation part 85, which is applied force by the return spring 83, toward the interior of the main body part 41 by abutting against the swing part 92.

After the operator OP swings the swinging part 92, which is in an upright position in the first position, into a horizontal position... Figure 22 Arrow P1 shown will be used when the release mechanism 85 of the sideways posture is pulled backward. Figure 23 As shown by arrow P2), the rear end of the rod 84 is pulled upward via line 86. This causes the rod 84 to swing downwards towards the front end, centered on the rod support pin 84P. Figure 23 As shown by arrow R1), the rear end of the clamp release member 82 is pressed down via roller 82R.

[0265] When the rear end of the clamping release member 82 is pressed down, the clamping release member 82 resists the force of the return spring 83 and swings upward toward the front end around the pin 82P. Figure 23 (See arrow R2 shown). Then, stop at a position where the upper surface of the clamping release pawl 82T is higher than the cam surface 81C (referred to as the "clamping release position"). Figure 23 , Figure 12B That is, when the operator (OP) moves the release operation unit 85 from the first position to the second position (pulling it backward), the clamping release member 82 moves from the standby position to the clamping release position (swinging).

[0266] Thus, when the release operation unit 85 moves from the first position to the second position, thereby moving the clamping release member 82 from the standby position to the clamping release position, the operating force of the release operation unit 85 is transmitted to the clamping release member 82 via the line 86 and the rod 84. At this time, the line 86 and the rod 84 become the transmission part DB that transmits the displacement of the release operation unit 85 to the clamping release member 82. Figure 22 as well as Figure 23 ).

[0267] Figure 24A as well as Figure 24B This is an explanatory diagram showing the part feeder 13 of one embodiment of the present invention before and after assembly with respect to the feeder base 22. When the part feeder 13 of this structure is installed on the feeder base 22, the operator OP, with the release operation unit 85 in the first position in an upright posture, inserts the front end of the insertion part 52 into the insertion slot 23S. Then, the main body 41 slides along the insertion slot 23S in the assembly direction. Figure 24A As shown by arrow At), the main body 41 is pressed into the depth side of the feeder base 22 until the front surface 41a of the main body 41 abuts against the feeder limiter 24.

[0268] When the main body 41 is pressed into the depth side of the feeder base 22, during this process, the recess 81K of the clamped member 81 on the part feeder 13 side engages with the fixing element 34 of the clamping mechanism 31 on the feeder base 22 side. Thus, the clamped member 81 is clamped by the clamping mechanism 31, and the part feeder 13 is fixed (clamped) relative to the feeder base 22. Figure 24B ).

[0269] Furthermore, during the process of pressing the main body 41 into the depth side of the feeder base 22, the upper pin 54 and lower pin 55 of the part feeder 13 are respectively inserted into the upper pin insertion hole 24A and lower pin insertion hole 24B of the feeder limiter 24, and the socket 57 of the part feeder 13 is connected to the plug 26 provided on the feeder base 22 side. Through the connection between the socket 57 and the plug 26, the control unit 44 on the part feeder 13 side is electrically connected to the control device 17 on the component assembly device 1 side.

[0270] Here, refer to Figure 25A , Figure 25B , Figure 26A , Figure 26B as well as Figure 26C The clamping action of the clamping mechanism 31 clamping the clamped component 81 is described in detail. Figure 25A as well as Figure 25B This is an illustration of the operation of the clamping mechanism 31 when the part feeder 13 is assembled on the feeder base 22 according to an embodiment of the present invention. Figure 26A , Figure 26B as well as Figure 26C This is an explanatory diagram of the operation of the clamping mechanism 31 when the part feeder 13 is assembled onto the feeder base 22 according to an embodiment of the present invention. When the insertion portion 52 of the part feeder 13 is inserted into the insertion slot 23S of the feeder base 22, the main body 41 is moved in the assembly direction (…). Figure 25A When the arrow At shown is pressed in, firstly, the cam surface 81C of the clamped member 81 abuts against the operated part 33 of the clamping mechanism 31. Figure 25A → Figure 25B Here, the highest point 81G in the front end 81F of the clamped member 81 is located at a lower position than the operated part 33 and therefore does not abut against the operated part 33. Instead, the cam surface 81C abuts against the operated part 33.

[0271] When the part feeder 13 is further pressed in the assembly direction from the state where the cam surface 81C abuts against the operated part 33, Figure 26A As shown by arrow At), the cam surface 81C, with its inclined shape, is pushed up by the operating part 33 and moves forward. Consequently, the arm 32 resists the force of the force-applying spring 36 and swings about the support shaft 22J in a direction that rises towards the rear end. Figure 26A Arrow M shown.

[0272] When arm 32 is pushed up by cam surface 81C and swings in the direction of rearward movement, the retainer 34 moves upward. Then, when the highest point of the rear end of cam surface 81C (highest point 81CG of the rear end of cam surface 81C) reaches directly below the operated part 33, the highest point 81G of the front end 81F reaches directly below the retainer 34 or passes slightly past the center of the retainer 34 in the assembly direction. Figure 26A During this period, the cam surface 81C functions to resist the force of the force-applying spring 36, which is required to secure the part feeder 13 relative to the feeder base 22 with sufficient clamping force, by lifting the retainer 34.

[0273] When the part feeder 13 is further pressed into the assembly direction and the front surface 41a of the main body 41 abuts against the feeder limiter 24, the clearance portion 81H of the clamped member 81 reaches directly below the operated portion 33, and the recessed portion 81K also reaches directly below the retainer 34. Figure 26B At this point, the operated part 33, having lost the support provided by the cam surface 81C, falls towards the clearance part 81H, and therefore the arm 32 swings in the rearward downward direction about the support shaft 22J. Figure 26B (See arrow N shown). Then, the retainer 34 descends with the swing of the arm 32 and is pressed against the recess 81K that moves directly downwards, engaging with the clamped member 81, thereby fixing (clamping) the part feeder 13 to the feeder base 22. Figure 26C as well as Figure 24B ).

[0274] As described above, in this embodiment, the clamping mechanism 31 is structured such that it includes a retainer 34 and an operable portion 33, which are mounted on an arm 32 that swings around a shaft (pin 82P) that is horizontally intersecting the assembly direction relative to the part feeder 13. The arm 32 extends in the opposite direction to the assembly direction (front) of the part feeder 13 (disengagement direction, rearward), and has the retainer 34 at a position separated rearward from the pin 82P, and the operable portion 33 at a position separated from the retainer 34 in the disengagement direction. Furthermore, the clamping member 81 pushes up the operable portion 33 using a cam surface 81C. The cam surface 81C is an inclined surface that tends to rise in the direction opposite to the assembly direction (disengagement direction) of the part feeder 13, and when the clamping member 81 moves in the assembly direction of the part feeder 13, it displaces the operable portion 33 upward. That is, instead of directly pushing up the fixing part 34 using the cam surface 81C, it is indirectly pushed up by operating the operating part 33.

[0275] As described above, the mounting position of the operated part 33 is farther from the support shaft 22J than the mounting position of the fixing part 34. Therefore, the clamped member 81 can push the fixing part 34 to a height that does not interfere with the highest point 81G of the front end 81F of the clamped member 81 with less force than when the fixing part 34 is directly pushed up. In addition, in conjunction with the force-amplifying effect based on the cam surface 81C, the reaction force from the clamping mechanism 31 when pressing the part feeder 13 into the feeder base 22 can be reduced. In other words, the pressing force when pressing the part feeder 13 into the feeder base 22 can be reduced.

[0276] Next, refer to Figure 27A , Figure 27B , Figure 28A , Figure 28B , Figure 29A as well as Figure 29B The clamp release action performed by the clamp release mechanism 80 will be explained. Figure 27A as well as Figure 27B This is an explanatory diagram showing the part feeder 13 before and after being removed from the feeder base 22 according to an embodiment of the present invention. Figure 28A as well as Figure 28B This is an explanatory diagram of the operation of the rod portion 84 and the clamping release member 82 when the part feeder 13 is removed from the feeder base 22 according to an embodiment of the present invention. Figure 29A as well as Figure 29B This is an explanatory diagram of the operation of the rod portion 84 and the clamping release member 82 when the part feeder 13 is removed from the feeder base 22 according to an embodiment of the present invention.

[0277] When the operator removes the part feeder 13 mounted on the feeder base 22, first, the swinging part 92 of the release operation unit 85 swings from the upright position to the horizontal position. Figure 22 (See arrow P1 shown). Then, the swinging part 92, which will become the sideways posture, will be pulled backward ( Figure 27A Arrow P2 shown in the diagram causes the entire part feeder 13 to move in the disengagement direction (rearward) from the feeder base 22. Figure 27A → Figure 27B ).

[0278] When the swinging part 92 is pulled backward by the operator OP, the sliding part 91 moves backward and causes the rod part 84 to swing downward in the front direction via the line 86. Figure 22 → Figure 23 , Figure 28A → Figure 28B Therefore, the operated part 33 within the clearance portion 81H of the clamped member 81 is pushed up by the clamp release claw 82T and raised to the same height as or higher than the highest point 81CG of the rear end of the cam surface adjacent to the clearance portion 81H. Figure 28B When the operated part 33 is raised to the same height as or higher than the highest point 81CG at the rear end of the cam surface, the retainer 34 disengages from the recess 81K. Figure 29A Thus, the clamping state based on the fixing element 34 is released.

[0279] Thus, in the part feeder 13 of this embodiment, the release operation part 85 and the lever part 84 are connected by a line 86. When the release operation part 85 is pulled backward toward the main body part 41, the lever part 84 swings, causing the retainer 34 to disengage from the clamped member 81 (specifically, the recess 81K). In this structure, the change of force direction is easy by using the line 86, so the mechanism that uses the release operation part 85 to operate the lever part 84 can be constructed in a lightweight and compact manner.

[0280] It should be noted that line 86 sometimes extends due to changes over time. When the extension of line 86 increases, even if the release operation part 85 is moved to the second position, the amount of pushing up by the operation part 33 by the clamping release claw 82T is insufficient. In this case, when the part feeder 13 is moved in the disengagement direction ( Figure 27A The arrow Re shown in the image slid when ( Figure 27AAs shown by arrow P2, not only does the highest point 81CG of the rear end of the clamping member 81 collide with the operated part 33, or the highest point 81G of the clamping member 81 collide with the fixing part 34, hindering the removal operation of the part feeder 13, but in the worst case, it cannot be removed from the feeder base 22. Therefore, in this embodiment, the sliding part 91 is provided with a line adjustment function to correct the effect caused by the extension of the line 86.

[0281] As described above, the position of the wire holder 111 relative to the sliding portion 91 in the Y direction can be changed within the length of the elongated hole 91H provided in the sliding portion 91 in the Y direction. When the position of the wire holder 111 is changed, the position of the swing direction of the clamping release member 82, which is linked to the rod portion 84, can be changed, ultimately adjusting the position (height) of the clamping release claw 82T. Therefore, by changing the position of the wire holder 111 relative to the sliding portion 91 in the Y direction, the distance LG between the front wall portion 91b of the sliding portion 91 and the head 86T of the wire 86 can be changed. Figure 21A as well as Figure 21B The position of the clamping release claw 82T is also adjusted proportionally to the change in distance LG. Figure 21A as well as Figure 21B This is a partial cross-sectional top view of the release operation section 85 provided in the part feeder 13 according to an embodiment of the present invention.

[0282] Thus, in this embodiment, the elongated hole 91H, nut 111N, and bolt 112 form a wire adjustment part WC, which assembles the wire retainer 111 onto the sliding part 91 to adjust the position of the clamp release member 82, thereby adjusting the position of the wire retainer 111 in the sliding direction (Y direction) of the sliding part 91. Figure 21A as well as Figure 21B ).

[0283] After the operator pulls the release operation unit 85 backward to release the clamping member 81 from the clamping member 34, they continue to pull the release operation unit 85 backward toward the main body 41. Figure 29B (P1 shown). As a result, the insertion portion 52 moves rearward and disengages from the feeder base 22, thus allowing the part feeder 13 to be removed from the feeder base 22. Meanwhile, the recess 81K of the clamping member 81 separates downward from the fixing member 34 (…). Figure 26C → Figure 29A After the operating part 33 moves along the cam surface 81C of the clamped member 81, Figure 28B → Figure 29A ), disengaging from cam surface 81C ( Figure 29B ).

[0284] Thus, in the parts feeder 13 of this embodiment, after the release operation part 85 is pulled rearward toward the main body 41 and the lever part 84 releases the clamping member 81 from the fixing member 34, if the release operation part 85 is further pulled rearward toward the main body 41, the insertion part 52 will disengage from the insertion slot 23S under the action of the pulling force. Therefore, the operator can smoothly perform both the release and removal of the parts feeder 13 by pulling the release operation part 85 in the disengagement direction (rearward).

[0285] Thus, in the part feeder 13 of this embodiment, the release operation unit 85, which is operated by the operator (OP) to set the main body 41 to a state where it can be removed from the feeder base 22, includes: a sliding part 91 that slides relative to the main body 41; and a swinging part 92 that swings the base 92K to the sliding part 91, and by swinging, can achieve an upright posture where the front end (operation side end 92S) approaches the main body 41 and a horizontal posture where the front end moves away from the main body 41. When the operator (OP) pulls the release operation unit 85 horizontally in the horizontal posture, the fixation of the main body 41 relative to the feeder base 22 is released, allowing the part feeder 13 to detach from the feeder base 22.

[0286] The clamping and releasing operation of this part feeder 13 relative to the feeder base 22 is extremely simple, and the clamping and releasing operation direction is consistent with the removal direction (sliding direction) of the part feeder 13 from the feeder base 22. Therefore, even when a robot performs these operations, it can be solved with simple operation. Thus, it is possible to prevent the situation where the cost increases due to the use of expensive robots that require complex movements. Furthermore, except when the part feeder 13 is removed from the feeder base 22, if the swing part 92 is in an upright position and approaches the main body 41, the swing part 92 will not become an obstacle to the operator's operation, thus improving workability.

[0287] The aforementioned component assembly production line's work instruction unit (SSB) Figure 1The system identifies the types of each part feeder 13 mounted on the feeder base 22 of the component assembly unit 1. When making production changes corresponding to the type of substrate KB being produced, if a part feeder 13 needs to be replaced, the system notifies the component assembly unit 1 of the part feeder 13 that should be replaced (removed from the feeder base 22). Then, the control device 17 of the component assembly unit 1, receiving the notification from the work instruction unit SSB, illuminates or flashes the light 63 on the part feeder 13 that should be replaced. After the operator (OP) detects the part feeder 13 with the light 63 illuminated or flashing, they locate the part feeder 13 that should be removed from the multiple part feeders 13 on the feeder base 22 using the light 63, and pull the swinging part 92 of the handle 51 of the part feeder 13 backward, thereby removing the part feeder 13 from the feeder base 22.

[0288] The operator needs to locate the part feeder 13 with the light 63 lit or flashing from among the multiple part feeders 13 arranged on the feeder base 22. Therefore, the arrangement of the light 63 on the operation panel 60 is preferably a layout that makes it easy to find the lit or flashing state of the light 63.

[0289] In this embodiment, the operation panel 60 is disposed in the corner 51E of the handle portion 51, which includes the rear surface 41b and the upper surface 41c. Compared to the conventional case where the operation panel 60 is only disposed on the upper surface 41c of the handle portion 51, the operation switch 61 and the lamp 63 can be configured with greater freedom. Therefore, the operation switch 61 and the lamp 63 can be configured separately, and their respective sizes can be increased, thereby improving the operability and visual confirmation of the operation panel 60. In particular, in this embodiment, the operation switch 61 is disposed on the upper surface 41c of the handle portion 51 in a manner that is easy for the operator to operate, while the lamp 63 is disposed on the rear surface 41b of the handle portion 51, so the operator is less likely to miss (easily notice) the lit or flashing lamp 63.

[0290] Furthermore, by positioning the light 63 on the rear surface 41b of the handle portion 51, the operator (OP) can easily distinguish the part feeder 13 that should be removed from other adjacent part feeders 13 when removing the part feeder 13 from the feeder base 22. That is, the light 63 is positioned on the tight edge of the release operation portion 85 (specifically, the swing portion 92), thus preventing human error from mistakenly removing a part feeder 13 adjacent to the one indicated by the light 63.

[0291] In this embodiment, the operation panel 60 has the following structure: a main panel 60A with an operation switch 61; a sub-panel 60B with a lamp 63; and a connecting portion 60C connecting the main panel 60A and the sub-panel 60B. This structure makes the operation panel 60 a single component, and the operation switch 61 and the lamp 63 can be arranged on both the upper surface 41c and the rear surface 41b of the handle portion 51, thus reducing the number of parts. Therefore, compared to manufacturing these panels separately, the operation of installing the operation panel 60 onto the handle portion 51, as well as the storage and management of the operation panel 60 before installation on the handle portion 51, is easier.

[0292] As explained above, in the part feeder 13 of this embodiment, when the release operation unit 85 is pulled horizontally in a horizontal position, the fixation (clamping) of the main body 41 relative to the feeder base 22 is released, and the part feeder 13 detaches from the feeder base 22. Therefore, the removal of the part feeder 13 from the feeder base 22 can be performed with extremely simple operation. In addition, the operating direction of the release operation unit 85 when the clamp is released (the pulling direction of the swing unit 92) is consistent with the removal direction (sliding direction) of the part feeder 13 from the feeder base 22. Therefore, even when a robot is used to perform these operations, the problem can be solved with simple operation, preventing the increase in cost due to the use of expensive robots that require complex movements. Furthermore, except when removing the part feeder 13 from the feeder base 22, if the swing unit 92 is in an upright position and approaches the main body 41, the swing unit 92 will not become an obstacle to the operator's operation, thus improving workability.

[0293] The embodiments of the present invention have now been described, but the present invention is not limited to the above description and various modifications are possible. For example, in the above embodiment, the transmission part DB that transmits the displacement of the release operation part 85 to the clamping release member 82 includes a line 86 and a rod part 84, but may also include other structures such as a connecting rod. In addition, in the above embodiment, the part feeder 13 is a belt feeder, but it is not limited to a belt feeder, and may also be a bulk feeder, a rod feeder, etc.
