[0029] In Japanese Patent Gazette No. 2020-109797, when the component assembly device is running, the assembly head, which is a heavy object, frequently repeats movement and stopping. Such movement of the assembly head excites the part feeder mounted on the feeder base. As a result, lateral vibration (sway) is generated in the part feeder. The sway makes the position of the component supply port unstable. Therefore, the adsorption accuracy of the components performed by the assembly head is reduced, and then the assembly accuracy of the components relative to the substrate is reduced. As described above, a pin is provided at the front end of the part feeder, and the pin is inserted into the component on the feeder base side, so that the sway of the component supply port is suppressed to a certain extent. However, if the axial acceleration of the assembly head continues to increase and the exciting force acting on the part feeder increases, and the part feeder continues to be narrowed and the rigidity of the main body is reduced, there is a possibility that the amplitude of the sway of the part feeder is too large and stable component supply cannot be performed.

[0030] An object of the present invention is to provide a parts feeder and a parts mounting device that can reduce the amplitude of yaw and perform stable parts supply.

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 It is a side view of the main part of the component mounting device 1 in one embodiment of the present invention.

[0032] The component assembly device 1 is a device that repeatedly performs component assembly operations of assembling components BH on a substrate KB carried in from an upstream process side and carrying it out to a downstream process side. Here, for the sake of convenience, the conveying direction of the substrate KB in the component assembly device 1 (the left-right direction when viewed from the operator OP) is set as the X-axis direction. The horizontal direction orthogonal to the X-axis direction (the front-back direction when viewed from the operator OP) is set as the Y-axis direction. In addition, the up-down direction is set as the Z-axis direction.

[0033] exist Figure 1 In FIG. 1 , the component mounting apparatus 1 includes a base 11 , a substrate conveying path 12 , a component feeder 13 , a mounting head 14 , a head moving mechanism 15 , a component recognition camera 16 , and a control device 17 .

[0034] The substrate transport path 12 is composed of a pair of belt conveyors 12a, and is extended in the X-axis direction on the base 11. The substrate transport path 12 carries in the substrate KB sent from the upstream process side, and positions the substrate KB at a predetermined work position.

[0035] exist Figure 1 In the embodiment, the feeder carriage 21 is connected to the end portion of the base 11 on the near front side (set as the rear side) when viewed from the operator OP. A feeder base 22 is provided on the upper portion of the feeder carriage 21.

[0036] The parts feeder 13 is mounted on the feeder base 22 in a detachable manner. The parts feeder 13 supplies the parts BH to the parts supply port 13K provided at the end on the inner side (front) when viewed from the operator OP. A plurality of parts feeders 13 can be mounted on the feeder base 22 side by side along the X-axis direction. If the feeder carriage 21 is connected to the base 11, the plurality of parts feeders 13 mounted on the feeder base 22 are connected to the base 11 together.

[0037] exist Figure 1 In FIG. 1 , the mounting head 14 includes a plurality of suction nozzles 14N extending downward. Each suction nozzle 14N can be moved up and down and rotated about the Z axis, and can generate a suction force at the lower end by a vacuum pressure supplied from a vacuum source (not shown).

[0038] The head moving mechanism 15 is constituted by, for example, an XY beam mechanism, and can move the mounting head 14 in a horizontal plane (in an XY plane) in a region above the base 11 .

[0039] exist Figure 1 In the embodiment, the component recognition camera 16 is disposed in the area between the substrate conveying path 12 on the base 11 and the feeder carriage 21 (i.e., the parts feeder 13). The component recognition camera 16 is disposed so that the imaging optical axis is directed upward. When the assembly head 14 that adsorbs the component BH to the suction nozzle 14N passes above, the component recognition camera 16 photographs each component BH adsorbed to the suction nozzle 14N.

[0040] The control device 17 controls the operation of each part constituting the component mounting device 1. Specifically, the control device 17 controls the conveying operation of the substrate KB by the substrate conveying path 12 and the positioning operation to the working position, and controls the supply operation of the component BH by each part feeder 13.

[0041] In addition, the control device 17 controls the lifting and rotating movements of each of the plurality of suction nozzles 14N provided in the assembly head 14, and controls the lower end of each suction nozzle 14N to generate a suction force for the component BH. In addition, the control device 17 controls the movement of the assembly head 14 by operating the head moving mechanism 15. Furthermore, the control device 17 controls the shooting movement of the component recognition camera 16.

[0042] When the component assembly device 1 performs a component installation operation, first, the substrate conveying path 12 receives the substrate KB sent from the upstream process side and positions it at the operation position. After the substrate KB is positioned, the head moving mechanism 15 operates to move the assembly head 14 above the part feeder 13. The assembly head 14 causes the components BH to be adsorbed to a plurality of suction nozzles 14N respectively. The assembly head 14 with the components BH adsorbed to the suction nozzles 14N moves in a manner passing above the component recognition camera 16. The component recognition camera 16 recognizes each component BH.

[0043] After the component recognition camera 16 recognizes the component BH, the head moving mechanism 15 moves the assembly head 14 to the top of the substrate KB. The assembly head 14 assembles the component BH to the target assembly coordinates set on the substrate KB. A series of actions consisting of the adsorption, recognition and assembly of the component BH are repeatedly performed. After all the components BH to be assembled on the substrate KB are assembled, the substrate conveying path 12 is operated to carry the substrate KB to the downstream process side. Thus, the component assembly operation equivalent to one substrate KB is completed.

[0044] In the component mounting device 1 having such a structure, in this embodiment, the characteristic lies in the structure of the parts feeder 13, which will be described below.

[0045] First, the structure of the feeder base 22 on which the parts feeder 13 is mounted will be described.

On the upper surface of the feeder base 22, a plurality of slots 23S extending in the Y-axis direction are formed by a plurality of slot forming members 23 having a T-shaped cross section extending in the Y-axis direction and arranged in the X-axis direction. Each part feeder 13 is selectively inserted and installed in one of the plurality of slots 23S. At this time, the part feeder 13 is inserted into the slot 23S from the near front side toward the inner side when observed by the operator OP.

The bracket 25 is provided with a connector 26 and a lower engaging pin 27 in a configuration corresponding to each slot 23S.

[0049] exist Figure 2 , Figure 3A as well as Figure 3B In the embodiment, a plurality of roller units 31 as clamped units are arranged side by side in the X-axis direction in the carriage 25 in an arrangement corresponding to the respective slots 23S.

[0050] Figure 4 FIG. 1 is a perspective view of a roller unit 31 provided in the parts feeder 13 according to an embodiment of the present invention. Figure 4 As shown, each roller unit 31 includes: a pair of arms 32, which have a shape extending as a whole in the Y-axis direction; a connecting portion 33, which connects the pair of arms 32; and a roller 34 as a clamped portion, which extends in the X-axis direction in a manner that connects the front end portions of the pair of arms 32 to each other.

[0051] An urging spring 35 is provided in a compressed state between the coupling portion 33 and the feeder base 22. The urging spring 35 causes the roller unit 31 to be urged downward as a whole.

[0052] Next, the structure of the parts feeder 13 will be described. Figure 2 , Figure 3A as well as Figure 3B In the figure, the part feeder 13 has a main body 41 that is extended in the YZ plane as a whole. The aforementioned component supply port 13K is provided at the upper front end of the main body 41. A component supply mechanism (not shown) that supplies components BH to the component supply port 13K is provided inside the main body 41.

[0053] A slot insertion portion 42 having a shape (a cross-section having an inverted T-shaped shape) that can be inserted into a slot 23S provided in the feeder base 22 is provided protruding downward at the front lower portion of the main body 41. The slot insertion portion 42 is inserted from the rear of the slot 23S. The main body 41 is pressed in until its front end portion abuts against the feeder stopper 24 provided in the feeder base 22.

[0054] Figure 5A 1 is a cross-sectional view showing a state in which the slot insertion portion 42 according to one embodiment of the present invention is inserted into the slot 23S of the feeder base 22 provided in the component mounting device 1. It should be noted that, Figure 5A The slot insertion portion 42 to be inserted into the slot 23S is shown in cross section together with the feeder base 22 .

[0055] exist Figure 2 , Figure 3A as well as Figure 3B In the embodiment, an upper pin 43 and a lower pin 44 as front engaging portions are respectively provided protruding forward at the front end of the main body 41. The upper pin 43 is provided at the upper portion of the front end of the main body 41. The lower pin 44 is provided at the lower portion of the front end of the main body 41.

[0056] exist Figure 2 , Figure 3A as well as Figure 3B In the embodiment, an engagement protrusion 45 is provided protruding downward at a position behind the slot insertion portion 42 at the lower portion of the main body 41. By inserting the slot insertion portion 42 into the inner portion of the slot 23S, the engagement protrusion 45 is engaged with (fitted into) the rear end portion of the slot 23S.

[0057] Figure 5B 1 is a cross-sectional view showing a state in which the engagement protrusion 45 in one embodiment of the present invention is engaged with the slot 23S of the feeder base 22 provided in the component mounting device 1. It should be noted that, Figure 5B The cross-sectional view shows a state in which the engagement protrusion 45 is engaged with (fitted into) the slot 23S.

[0058] like Figure 5B As shown, the dimension D of the engaging protrusion 45 in the slot 23S in the slot width direction is slightly smaller than the slot width MH of the slot 23S. Specifically, the dimension D is larger than the width direction dimension W ( Figure 5A ) and is smaller than the slot width MH of the slot 23S (ie, W<D<MH).

[0059] exist Figure 2 , Figure 3A as well as Figure 3B In the embodiment, a downward extending protrusion 46 extending downward is provided at the rear of the main body 41. A feeder side terminal 47 is provided protruding forward on the downward extending protrusion 46, and the feeder side terminal 47 is connected to the aforementioned connector 26 provided on the feeder base 22 side when the main body 41 is mounted on the feeder base 22.

The front end of the lower engaging member 48 is a curved portion 48K that is curved upward. A lower engaging portion 48H consisting of an opening is provided at the center of the curved portion 48K. When the slot insertion portion 42 is inserted into the inner side of the slot 23S, the lower engaging pin 27 engages with the lower engaging portion 48H.

[0061] Figure 6 is a perspective side view of a portion of the parts feeder 13 in one embodiment of the present invention. Figure 7 FIG. 1 is a perspective side view of a portion of the parts feeder 13 in one embodiment of the present invention. Figure 3A , Figure 3B , Figure 6 as well as Figure 7 In the embodiment, a clamping member 51 is provided at a position of the main body portion 41 behind the slot insertion portion 42 .

[0062] The clamping member 51 has a shape extending in the Y-axis direction as a whole. The front end side of the clamping member 51 is exposed in front of the downwardly extending protrusion 46. A recessed portion 51K with an upwardly open shape is provided at the front end of the clamping member 51. The front end side of the recessed portion 51K becomes a clamping claw 51F protruding upward.

[0063] The clamping member 51 is supported by a swing pin 51P which is mounted on the main body 41 at both ends and extends in the X-axis direction, and is configured to be able to swing freely around the swing pin 51P. The clamping member 51 is in a substantially horizontal posture, and in the claw lowering position ( Figure 6 ) and the claw raising position ( Figure 7 When the clamping member 51 moves (swings) from the claw lowering position to the claw raising position, the clamping claw 51F moves from the bottom to the top in front of the lower extending protrusion 46.

[0064] exist Figure 6 as well as Figure 7 In the embodiment, an operating member 52 is provided at the upper rear end of the main body 41 so as to be movable in the front-rear direction (Y-axis direction). The rear portion of the operating member 52 is configured to protrude rearward from the rear end of the main body 41. The operating member 52 is disposed at a first position ( Figure 6 ) and the second position ( Figure 7 ) can be moved freely between them.

[0065] exist Figure 6 as well as Figure 7In the embodiment, a cam block 53 is provided below the operation member 52 in a manner fixed to the main body 41 .

[0066] Fig. 8A It is a top view of the alternating mechanism portion 58 provided in the parts feeder 13 in one embodiment of the present invention. Figure 8B FIG. 5 is a side sectional view of an alternating mechanism 58 provided in the parts feeder 13 in one embodiment of the present invention. Fig. 8A as well as Figure 8B Cam groove 53M is shown.

[0067] exist Figure 6 , Figure 7 , Fig. 8A as well as Figure 8B In the embodiment, a pivot pin 54 extending in the Z-axis direction is provided in the middle portion of the operating member 52 in the front-to-back direction. One end of a swing head piece 55 is pivotally supported at the lower end of the pivot pin 54. A cam rod 56 extending downwardly and protruding is connected to the other end of the swing head piece 55. The lower end of the cam rod 56 is located in the cam groove 53M. The swing head piece 55 can swing freely in a horizontal plane with the pivot pin 54 as a fulcrum. Therefore, the cam rod 56 can move on a circular arc track centered on the pivot pin 54.

[0068] exist Fig. 8A as well as Figure 8B In the embodiment, a spring insertion portion 52S is provided in a manner extending forward at the front end portion of the operation member 52. A return spring 57 composed of a coil spring is inserted through the spring insertion portion 52S.

[0069] The rear end side of the return spring 57 abuts against the operating member 52. The front end side of the return spring 57 abuts against a portion of the main body 41, thereby applying force to the operating member 52 backward. When the operating member 52 is pressed from the rear to the front of the main body 41, the operating member 52 moves forward and compresses the return spring 57. The compressed return spring 57 applies a push-back force to the operating member 52 backward.

[0070] Fig. 9 It is a partial plan view of the cam block 53 which the alternating mechanism part 58 which the parts feeder 13 in one embodiment of the present invention has. FIG. 10A to FIG. 10D This is a diagram for explaining the operation of the alternating mechanism 58 included in the parts feeder 13 in one embodiment of the present invention. Fig. 9 In FIG. 5 , the cam groove 53M formed in the cam block 53 is a so-called heart-shaped cam groove.

[0071] When the cam bar 56 is located at the rearmost position P1 in the cam groove 53M ( Fig. 10A), the cam rod 56 receives the force from the return spring 57 and contacts the wall surface of the cam groove 53M from the front. At this time, the operating member 52 becomes stationary at the position P1. The position of the operating member 52 in this state corresponds to the first position ( Figure 6 ).

[0072] like Fig. 10A In this way, when the operator OP pushes the operating member 52 located at the first position forward, the operating member 52 moves forward while compressing the return spring 57. As a result, the cam bar 56 moves from the position P1 to the position P2 in the cam groove 53M. Fig. 9 The positions P2 and P3 shown in the figure are moved to the position P4 ( Fig. 10A → Fig. 10B → Fig. 10C ). The cam bar 56 abuts against the wall surface of the cam groove 53M from the rear at the position P4.

[0073] When the cam bar 56 contacts the wall surface of the cam groove 53M, the operator OP cannot further press the operation member 52 forward. Thus, the operator OP senses that the operation member 52 has reached the stroke end in the pressing direction and releases his hand from the operation member 52 .

[0074] When the operator OP releases the operating member 52, the operating member 52 is urged by the return spring 57 to move backward. As a result, the cam bar 56 moves from the position P4 to the Fig. 9 The position P5 moves ( Fig. 10C → Fig. 10D ). The cam rod 56 abuts against the wall surface of the cam groove 53M from the front at position P5 due to the force of the return spring 57. In this state, the operating member 52 cannot move further backward and becomes stationary at position P5 ( Fig. 10D The position of the operating member 52 in this state corresponds to the aforementioned second position ( Figure 7 ).

[0075] Figures 11A to 11C The figure is used to explain the operation of the alternating mechanism 58 of the parts feeder 13 in one embodiment of the present invention. When the operator OP presses the operating member 52 forward from the state where the operating member 52 is in the second position, the operating member 52 moves forward while compressing the return spring 57. At this time, the cam rod 56 moves from the position P5 to the position P6 in the cam groove 53M. Fig. 9 Position P6 is moved as shown ( Fig. 10D → Fig.11A ).

[0076] The cam bar 56 contacts the wall surface of the cam groove 53M from behind at position P6. When the cam bar 56 contacts the wall surface of the cam groove 53M, the operator OP cannot further press the operating member 52 forward. As a result, the operator OP senses that the operating member 52 has reached the end of the stroke in the pressing direction, and releases the operating member 52.

[0077] When the operator OP releases the operating member 52, the operating member 52 is urged by the return spring 57 to move backward. As a result, the cam bar 56 passes from the position P6 to the position P7. Fig. 9 from position P7 to position P1 ( Fig.11A → Fig. 11B → Fig. 11C The cam bar 56 abuts against the wall surface of the cam groove 53M from the front and stops at the position P1 due to the force of the return spring 57 ( Fig. 11C ). As a result, the operation member 52 is returned to the first position.

[0078] In this way, the cam block 53, the cam rod 56 and the return spring 57 of the parts feeder 13 constitute an alternating mechanism 58 (which alternately switches the position of the operating member 52 between the first position and the second position set in the pressing direction of the operating member 52 each time the operating member 52 is pressed toward the front of the main body 41. Figure 6 , Figure 7 , Fig. 8A as well as Figure 8B ).

[0079] exist Figure 6 as well as Figure 7 In the embodiment, a wire 60 is provided in the main body 41 to connect the operating member 52 and the clamping member 51. One end (upper end) of the wire 60 is attached to the operating member 52 via an upper wire nut 60A. The other end (lower end) of the wire 60 is attached to the wire fixing portion 46K in the main body 41 via a lower wire nut 60B.

[0080] exist Figure 6 as well as Figure 7 In the embodiment, the middle portion of the wire rope 60 is supported by a plurality of pulleys (a first pulley 61, a second pulley 62, a third pulley 63, and a fourth pulley 64). The first pulley 61 is mounted on the cam block 53. The second pulley 62 and the third pulley 63 are mounted on the wire rope fixing portion 46K. The fourth pulley 64 is mounted on a portion of the clamping member 51 that is further rearward than the swing pin 51P.

[0081] The wire rope 60 installed on the upper end side of the operating member 52 extends rearward in the section to the first pulley 61, extends downward between the first pulley 61 and the second pulley 62, extends forward between the second pulley 62 and the third pulley 63, extends upward between the third pulley 63 and the fourth pulley 64, and extends downward in the section from the fourth pulley 64 to the lower end side.

[0082] exist Figure 6 as well as Figure 7 In the embodiment, a spring member 65 is provided under compression between a rear portion of the swing pin 51P of the clamp member 51 (specifically, a portion between the swing pin 51P and the fourth pulley 64 ) and the wire rope fixing portion 46K.

Fig.13 FIG. 1 is a partial perspective view of a part feeder 13 in an embodiment of the present invention when it is installed on the feeder base 22. The spring member 65 applies force to the clamping member 51 toward the claw lowering position. Figure 6 As shown, when the operating member 52 is located at the first position, the clamping member 51 is located at the claw lowering position (also refer to Fig. 12A ).

[0084] Thus, when the operator OP pushes the operating member 52 forward from the state where the operating member 52 is located at the first position (the clamping member 51 is located at the claw lowering position), the upper wire rope nut 60A is pulled in the forward moving direction by the operating member 52 ( Fig. 10A → Fig. 10B → Fig. 10C as well as Fig. 12A → Fig. 12B ). And, the moving distance of the operating member 52 during this period, that is, the distance SS between the first position and the second position ( Fig. 12B ) is pulled upward between the first pulley 61 and the second pulley 62. And, accordingly, the rear side of the clamping member 51 is pulled downward by the wire rope 60 via the fourth pulley 64. Therefore, the clamping member 51 is swung with the swing pin 51P as a fulcrum while compressing the spring member 65 ( Fig. 12B The arrow R in the figure shows the position where the clamping jaws are raised ( Fig. 12B ).

[0085] On the other hand, when the operator OP pushes the operating member 52 forward from the state where the operating member 52 is located at the second position (the state where the clamping member 51 is located at the claw-lifted position), the rear side of the clamping member 51 is pushed up by the force of the spring member 65. As a result, the clamping member 51 swings with the swing pin 51P as a fulcrum ( Fig. 12B → Fig. 12A ), thereby resetting to the claw lowered position ( Fig. 12A ).

[0086] When the parts feeder 13 of such a structure is mounted on the feeder base 22, the operator OP inserts the slot insertion portion 42 horizontally into the slot 23S from the rear of the slot 23S with the operating member 52 in the first position (the clamping member 51 in the claw lowering position). Then, the main body 41 is pressed into the inner side of the feeder base 22 until the front end of the main body 41 abuts against the feeder stopper 24 ( Figure 3A → Figure 3B ). As a result, the upper pin 43 is inserted into the upper pin insertion hole 24A. The lower pin 44 is inserted into the lower pin insertion hole 24B. And, the engaging protrusion 45 is engaged with (engaged in) the rear end of the slot 23S. The lower engaging pin 27 on the feeder base 22 side is engaged with the lower engaging portion 48H on the part feeder 13 side.

[0087] The lower engaging portion 48H and the engaging protrusion 45 are respectively referred to as the rear engaging portion in the present embodiment. Here, the "rear engaging portion" refers to a portion that is provided at a position of the main body 41 that is more rearward than the slot insertion portion 42 and that engages with a second member (in the present embodiment, the lower engaging pin 27) or the slot 23S as a member on the feeder base 22 side that is different from the roller 34 as the clamped portion when the slot insertion portion 42 is inserted into the slot 23S.

[0088] When the slot insertion portion 42 is inserted into the inner side of the slot 23S, the feeder side terminal 47 is inserted into the connector 26, thereby electrically connecting the part feeder 13 to the control device 17 of the component assembly device 1. Thus, the operation of the part feeder 13 can be controlled from the control device 17.

[0089] When the slot insertion portion 42 of the parts feeder 13 is inserted into the inner side of the slot 23S of the feeder base 22, the clamping claw 51F of the clamping member 51 located at the claw lowering position does not contact the roller 34 but reaches below it (below the roller 34) ( Figure 3B ).

[0090] After the front end of the part feeder 13 with the slot insertion portion 42 inserted into the slot 23S is brought into contact with the feeder stopper 24, the operator OP stops pressing the main body 41 into the inner side of the feeder base 22 and presses the operating member 52 forward. As a result, the operating member 52 moves from the first position to the second position. Therefore, the clamping member 51 moves (swings) from the claw lowering position to the claw raising position via the wire rope 60. As a result, the clamping claw 51F rises and overcomes the force of the biasing spring 35 to push up the roller 34 ( Fig. 12A → Fig. 12B Therefore, the roller 34 is clamped by the clamping member 51 ( Fig. 12B as well as Fig.13 ). Thus, the installation of the parts feeder 13 to the feeder base 22 is completed, and thereafter, the components BH can be supplied through the parts feeder 13.

[0091] As described above, in a state where the roller 34 is clamped by the clamping member 51, the front engaging portion (upper pin 43 and lower pin 44) provided at the front end portion of the main body 41 engages with the first member (feeder stopper 24) on the feeder base 22 side. In addition, the lower engaging portion 48H as the rear engaging portion engages with the lower engaging pin 27 of the member (second member) on the feeder base 22 side that is different from the roller 34 ( Fig.13 ). The lower engaging portion 48H engages with the feeder base 22 side at a position sufficiently away from the front engaging portion. Therefore, the lateral swing of the parts feeder 13 is effectively suppressed.

[0092] In addition, in the state where the roller 34 is clamped by the clamping member 51, the engaging protrusion 45, which is also a rear engaging portion, is engaged with (inserted into) the slot 23S. As described above, the dimension D of the engaging protrusion 45 in the slot 23S width direction is slightly smaller than the slot width MH of the slot 23S, so that the engaging protrusion 45 is engaged with the slot 23S in a state where the swing is smaller than the slot insertion portion 42. Therefore, the lateral swing of the parts feeder 13 can also be effectively suppressed by the engaging protrusion 45.

[0093] Thus, in the present embodiment, the rigidity of the parts feeder 13 against lateral movement in the state of being mounted on the feeder base 22 becomes extremely high. Therefore, even when the parts feeder 13 is excited with a large exciting force due to the frequent repetitive movement and stopping of the assembly head 14 during the operation of the parts assembly device 1, it is possible to suppress the lateral movement of the parts feeder 13. Therefore, the amplitude of the lateral movement of the parts supply port 13K can be suppressed to a small amount.

[0094] When the operator OP removes the parts feeder 13 mounted on the feeder base 22, he presses the operating member 52 in the same direction as when the parts feeder 13 is fixed to the feeder base 22, that is, in the forward direction. When the operating member 52 is pressed and moved from the second position to the first position, the clamping member 51 moves (sways) from the claw raising position to the claw lowering position due to the force of the spring member 65, so that the clamping claw 51F moves downward from the roller 34 ( Fig. 12B → Fig. 12A ). Therefore, the clamping state of the roller 34 is released.

[0095] Thus, in the present embodiment, the alternating mechanism 58, the wire rope 60, and the spring member 65 constitute a position switching mechanism 70 (which switches the position of the clamping member 51 between the clamping position for clamping the roller 34 as the clamped portion and the clamping release position for releasing the clamping of the roller 34) each time the pressing operation of the operating member 52 is performed. Figure 3A , Figure 3B , Figure 6 as well as Figure 7 ). Thus, the operator OP can clamp and release the roller 34 simply by pressing the operating member 52 in the same direction (forward) relative to the main body 41. In addition, the operating direction (pressing direction) of the operating member 52 is consistent with the direction in which the slot insertion portion 42 is inserted into the slot 23S. Therefore, when the robot is operated to install the part feeder 13 on the feeder base 22, the operating member 52 can be operated using the action axis (action axis for inserting the slot insertion portion 42 into the slot 23S) that the robot obviously has.

[0096] As described above, in the present embodiment, there is an alternating mechanism portion 58, which alternately switches the position of the operating member 52 between the first position and the second position each time the operating member 52 is pressed toward the front of the main body 41; a wire rope 60, which connects the operating member 52 to the clamping member 51; and a spring member 65, which applies force to the clamping member 51 from the clamping position toward the clamping release position side. And, when the operating member 52 switches position from the first position to the second position, the clamping member 51 moves (sways) from the clamping release position to the clamping position via the wire rope 60. In addition, when the operating member 52 switches position from the second position to the first position, the clamping member 51 moves (sways) from the clamping position to the clamping release position by the force of the spring member 65.

[0097] After the clamping state of the roller 34 is released, the operator OP slides the main body 41 backward and pulls the slot insertion portion 42 out of the slot 23S. In this process, the upper pin 43 is disengaged from the upper pin insertion hole 24A. The lower pin 44 is disengaged from the lower pin insertion hole 24B. The engaging protrusion 45 is disengaged from the slot 23S. In addition, the feeder side terminal 47 is disengaged from the connector 26. The lower engaging pin 27 is disengaged from the lower engaging portion 48H. Thus, the removal of the parts feeder 13 from the feeder base 22 is completed.

[0098] As described above, in the part feeder 13 (and the component assembly device 1) in the present embodiment, the structure is as follows: when the slot insertion portion 42 is inserted into the slot 23S, not only the front engaging portion (upper pin 43 and lower pin 44) provided at the front end portion of the main body 41 engages with the first component (feeder stopper 24) on the feeder base 22 side, but also the lower engaging portion 48H as the rear engaging portion engages with the lower engaging pin 27 as the second component on the feeder base 22 side, and the engaging protrusion 45 also engages with the slot 23S.

[0099] Therefore, the rigidity of the part feeder 13 against lateral movement when it is mounted on the feeder base 22 is extremely high. Therefore, even when the part feeder 13 is excited with a large excitation force due to the frequent repetitive movement and stop of the assembly head 14 during the operation of the component assembly device 1, the amplitude of the lateral movement of the part feeder 13 can be reduced to perform stable component supply. Therefore, the reduction in the adsorption accuracy of the component BH by the assembly head 14 can be suppressed, thereby improving the assembly accuracy of the component BH relative to the substrate KB.

[0100] So far, the embodiment of the present invention has been described, but the present invention is not limited to the above content, and various deformations can be made. For example, in the above embodiment, the engaging protrusion 45 is configured to engage with the slot 23S, but it is not limited to this. The engaging protrusion 45 can also be configured to engage with a protrusion engaging portion (not shown) provided at a position of the feeder base 22 that is more rearward than the slot 23S (a member on the feeder base 22 side that is different from the roller 34 that is the clamped portion). In this case, the groove width of the protrusion engaging portion does not need to be the same as the groove width MH of the slot 23S, but can be larger than the groove width MH. In addition, when the groove width of the protrusion engaging portion is larger than the groove width MH of the slot 23S, the dimension D of the engaging protrusion 45 in the groove width direction of the slot 23S can be increased accordingly (in order to embed the protrusion engaging portion).

[0101] In addition, in the above-mentioned embodiment, as the rear engaging portion (a member that engages with the slot 23S or a member (second member) on the feeder base 22 side different from the roller 34 when the slot insertion portion 42 is inserted into the slot 23S) provided at a position behind the slot insertion portion 42 of the main body 41, the lower engaging portion 48H and the engaging protrusion 45 are shown, but the present invention is not limited thereto. The rear engaging portion may be only one of the lower engaging portion 48H and the engaging protrusion 45, or may be provided separately.

[0102] The present invention provides a parts feeder and a parts assembly device capable of reducing the amplitude of yaw and performing stable parts supply.
