Detailed Description
Before explaining the embodiments of the present invention, a description will be given of the passage of implementing the present invention.
In the prior art, the suction nozzle frame can be automatically assembled and disassembled during maintenance. However, in a state where the mounting head is mounted on the component mounting apparatus or the maintenance-dedicated apparatus, maintenance is performed while controlling the mounting head in accordance with the maintenance program. Therefore, the place where maintenance is performed is limited. Accordingly, it is desirable that the nozzle holder can be attached to and detached from the shaft member by a simple operation even in a state where the mounting head is detached from the component mounting apparatus and in a state where power is not supplied to the component mounting apparatus.
Accordingly, the present invention provides a nozzle rack attachment/detachment device and a head maintenance method that can easily attach/detach a nozzle rack to/from a head.
An embodiment of the present invention will be described in detail below with reference to the drawings. The configuration, shape, and the like described below are examples for illustration, and may be changed as appropriate according to specifications of the component mounting apparatus, the mounting head, the nozzle rack, and the nozzle rack attaching/detaching apparatus. Hereinafter, the same reference numerals are given to corresponding elements in all drawings, and repetitive description thereof will be omitted. In fig. 1 and a part of the following, an X direction (a left-right direction in fig. 1) of a substrate conveyance direction and a Y direction (a vertical direction in fig. 1) of the substrate conveyance direction are shown as two axial directions orthogonal to each other in a horizontal plane. In fig. 2 and some of the following, a Z direction (vertical direction in fig. 2) is shown as a height direction orthogonal to a horizontal plane. The Z direction is the up-down direction in the case where the component mounting device is provided on the horizontal plane.
First, the structure of the component mounting apparatus 1 will be described with reference to fig. 1. In fig. 1, a substrate conveying mechanism 2 is provided in the center of a base 1a so as to be movable in the X direction. The substrate transport mechanism 2 transports the substrate 3 carried in from the upstream side in the X direction, and positions and holds the substrate at a mounting work position of a mounting head (hereinafter referred to as a "mounting head") described below. The substrate transport mechanism 2 transports the substrate 3 after the component mounting operation is completed downstream. The component supply units 4 are provided on both sides of the substrate transport mechanism 2 in the Y direction.
A plurality of tape feeders 5 are mounted in parallel in the X direction in both component feeders 4. The tape feeder 5 advances the carrier tape of the bag body in which the component is accommodated in a direction (tape feed direction) from the outside of the component supply section 4 toward the substrate conveying mechanism 2 at a pitch, thereby supplying the component to the component take-out position where the component is picked up by the mounting head.
In fig. 1, Y-axis tables 6 having a linear drive mechanism are disposed at both ends in the X direction of the upper surface of the base 1 a. A beam 7 having a linear mechanism is coupled to the Y-axis table 6 so as to be movable in the Y-direction. The beam 7 is mounted with a mounting head 8 so as to be movable in the X direction. A suction nozzle (hereinafter, simply referred to as a "suction nozzle") for vacuum sucking and holding the component is mounted at the lower end portion of the mounting head 8.
The Y-axis table 6 and the beam 7 constitute a mounting head moving mechanism that moves the mounting head 8 in the horizontal direction (X-direction, Y-direction). The mounting head moving mechanism and the mounting head 8 repeatedly perform a series of operations of component mounting operation, that is, vacuum suction and pickup of components by the suction nozzle from the component take-out position of the tape feeder 5 mounted on the component supply section 4, and transfer to the mounting position of the substrate 3 held by the substrate conveying mechanism 2 for mounting.
In fig. 1, a mounting head camera 9 which is located on the lower surface side of the beam 7 and moves integrally with the mounting head 8 is mounted on the beam 7. By the movement of the mounting head 8, the mounting head camera 9 is moved to a position above the substrate 3 positioned at the mounting operation position of the substrate transfer mechanism 2, and a substrate mark (not shown) provided on the substrate 3 is photographed to identify the position of the substrate 3.
A component recognition camera 10 is provided between the component supply section 4 and the substrate conveyance mechanism 2. When the mounting head 8 from which the component is taken out from the component supply section 4 is positioned above the component recognition camera 10, the component recognition camera 10 photographs the component held by the suction nozzle from below. In the component mounting operation of the component to the board 3 by the mounting head 8, the recognition result of the board 3 by the mounting head camera 9 and the recognition result of the component by the component recognition camera 10 are superimposed to correct the mounting position.
Next, the structure of the mounting head 8 will be described with reference to fig. 2. The mounting head 8 is a multi-connection type mounting head having a plurality (twelve in this case) of nozzle units 11 arranged in parallel. The mounting head 8 is detachably attached to the beam 7 via a coupling plate 8 a. The nozzle units 11 are each configured such that the shaft member 20 extends downward from the nozzle lifting drive unit 11a, and the nozzle 40 is detachably mounted on the nozzle holder 30 detachably coupled to the lower end portion of the shaft member 20.
The nozzle lifting drive units 11a each have a nozzle lifting mechanism that lifts a lifting shaft (not shown) coupled to the shaft member 20 by a linear motor. The shaft member 20 is driven in the up-down direction by driving the nozzle lifting mechanism, thereby lifting and lowering the nozzles 40 mounted to the nozzle frame 30 individually.
A θ -axis motor 12 is disposed laterally of the multi-row nozzle unit 11 so that the drive shaft is directed downward. The belt 12c is regulated by a driving pulley 12a coupled to the driving shaft and a driven pulley 12b fitted to each shaft member 20. By driving the θ -axis motor 12, the shaft member 20 rotates θ together with the suction nozzle 40 mounted on the suction nozzle holder 30, and thereby the component held by the suction nozzle 40 is aligned in the θ direction. Here, θ rotation means rotation in the θ direction, which is a direction parallel to the circumferential direction of a circle centered on the Z direction. That is, the θ direction becomes the rotation direction of the suction nozzle 40.
Next, the structure of the nozzle frame 30 and the nozzle 40 will be described with reference to fig. 3 to 5C. As shown in fig. 3, a housing member 21 is fixed to the shaft member 20 so that the shaft member 20 passes vertically. The nozzle holder 30 is coupled to the lower end of the shaft member 20 via the housing member 21. The nozzle holder 30 is configured such that two holding members 32 are pressed by tension spring members 33 on both side surfaces of a main body 31 provided with a vertically penetrating slide hole 31 a. The suction nozzle 40 is detachably held by two clamping members 32 at the lower end of the suction nozzle holder 30.
Fig. 4 shows a state in which the suction nozzle 40 is removed from the suction nozzle holder 30 and the suction nozzle holder 30 is removed from the shaft member 20 in the above-described configuration. Fig. 5A to 5C show a section A-A in fig. 3. And the cross section of the housing member 21 and a part of the nozzle holder 30 (a part of the upper portion 31d of the main body portion 31) in fig. 3 corresponds to the B-B cross section in fig. 5A.
As shown in fig. 3 and 4, the suction nozzle 40 is configured such that a clamped portion 40a to be clamped and held by the suction nozzle holder 30 is arranged on the upper surface side of the circular flange portion 40 c. A suction shaft 40d having a suction hole 40e and extending downward is provided on the lower surface side of the flange 40 c. The clamped portion 40a is provided with an engagement notch portion 40b in which a pair of pin members 31c are engaged, and the pair of pin members 31c radially protrude in the horizontal direction from an engagement portion 31b provided at the lower portion of the main body portion 31.
When the suction nozzle 40 is held by the nozzle holder 30, in the state shown in fig. 4, the fitting portion 31b is fitted into the fitting portion 40f provided in the suction nozzle 40, and the pin member 31c is fitted into the fitting cutout portion 40 b. Further, the clamped portion 40a is clamped from both sides by the clamping member 32, and clamped by the elastic force of the tension spring member 33. Thus, as shown in fig. 3, the suction nozzle 40 is mounted to the suction nozzle holder 30.
As shown in fig. 4, the shaft member 20 protruding from the lower side of the housing member 21 constitutes a slide shaft 20b that slides in engagement with the slide hole 31a of the main body 31 of the nozzle frame 30. An insertion opening 21a is provided on the lower surface side of the housing member 21. When the nozzle holder 30 is mounted to the housing member 21, the upper portion 31d of the main body 31 is fitted into the fitting opening 21a. A coil-shaped compression spring member 34 is mounted on the upper portion 31d of the main body 31, and the lower end portion of the compression spring member 34 abuts against the main body 31.
When the nozzle holder 30 is assembled to the shaft member 20, the upper portion 31d of the main body 31 is fitted into the fitting opening 21a of the housing member 21, and the slide shaft 20b is fitted into the slide hole 31a so as to be slidable in the up-down direction as indicated by the dot-dash arrow a in fig. 4. Thereby, the nozzle frame 30 is mounted to the shaft member 20 in a state in which the displacement in the up-down direction is allowed, and the nozzle frame 30 is guided in the up-down direction. The compression spring member 34, the upper end of which abuts the lower surface of the housing member 21, applies a downward force to the main body 31 of the nozzle frame 30.
As shown in fig. 3, in a state in which the suction nozzle 40 is mounted on the nozzle holder 30 and the nozzle holder 30 is mounted on the shaft member 20, the suction hole 20a of the shaft member 20 communicates with the suction hole 40e via the slide hole 31a and the fitting portion 40f (fig. 4). By driving the vacuum suction source 22 in this state and performing vacuum suction from the suction hole 20a, the suction nozzle 40 sucks and holds the component P at the lower end portion of the suction shaft 40 d.
A pair of pin-shaped locking members 31e protruding to both sides are provided near the upper end portion of the upper portion 31d of the main body 31 (see also fig. 5B and 5C). In a state where the nozzle holder 30 is mounted on the shaft member 20, the upper portion 31d of the main body 31 is fitted into the fitting opening 21a provided in the housing member 21. As shown in fig. 5A, the housing member 21 is provided with a pair of opposed horizontal groove portions 21b and a pair of opposed vertical groove portions 21c at positions orthogonal to each other so as to communicate with the fitting opening portion 21a. The horizontal groove portion 21b and the vertical groove portion 21c are connected by a notch portion 21 d. The cutout portion 21d is formed by horizontally cutting out a side surface portion of the case member 21 in a predetermined height dimension in a cutout range shown by a broken line in fig. 5A.
As shown in fig. 5A, the horizontal groove portion 21b and the vertical groove portion 21c are formed to penetrate from the fitting opening portion 21a to the outside of the case member 21. The vertical groove portion 21c located at one end of the notch portion 21d is formed in a planar shape through which the locking member 31e can pass up and down without interference when the nozzle holder 30 is attached to the shaft member 20 from below or detached from the shaft member 20. The horizontal groove portion 21b located at the other end portion of the cutout portion 21d is formed by cutting the lower end portion of the cutout portion 21d further downward by a predetermined depth dimension with a width dimension in which the locking member 31e can be fitted.
Fig. 5B and 5C show the fitting operation of the main body 31 to the housing member 21 when the nozzle holder 30 is assembled to the shaft member 20. That is, when the nozzle holder 30 is assembled to the shaft member 20, first, as shown in fig. 5B, the slide shaft 20B is fitted into the slide hole 31a (see fig. 4) of the body 31. At this time, the nozzle holder 30 is pushed up from the lower surface side of the housing member 21 in a state where the locking member 31e of the main body 31 is aligned with the vertical groove portion 21c of the housing member 21, and the locking member 31e reaches the height of the cutout portion 21 d. Hereinafter, the height position of the nozzle frame 30 at this time is referred to as "up-to-height".
When the nozzle holder 30 reaches the upper reaching height, the nozzle holder 30 is rotated about the shaft member 20 by about 90 degrees in the counterclockwise direction when viewed from above (arrow B in fig. 5B). Thereby, the locking member 31e rotates in the notch portion 21d to reach the position of the horizontal groove portion 21 b. Hereinafter, a direction (arrow b) in which the locking member 31e is rotated from the position of the vertical groove portion 21c to the position of the horizontal groove portion 21b is referred to as a "locking direction".
Next, the nozzle holder 30 is lowered, and the locking member 31e is fitted into the horizontal groove portion 21b as shown in fig. 5C. Thereby, the rotational position of the nozzle holder 30 about the nozzle axis is restricted, and the nozzle holder is mounted to the housing member 21 in a correct positional relationship. At this time, as shown in fig. 3, the locking member 31e is biased downward by the compression spring member 34 and locked by the bottom surface of the horizontal groove portion 21b, thereby preventing the nozzle frame 30 from falling off. The locking member 31e is set to a length that the tip end portion of the locking member 31e protrudes to the outside of the housing member 21 in a state where the nozzle holder 30 is mounted to the housing member 21. In this way, the nozzle holder 30 is mounted on the shaft member 20 of the mounting head 8.
When the nozzle holder 30 is detached from the shaft member 20, the upper portion 31d of the main body 31 is separated from the insertion opening 21a by performing the operation reverse to the above-described procedure. That is, the nozzle holder 30 is lifted up to the upper level, rotated by about 90 degrees in the clockwise direction, and the locking member 31e is aligned with the vertical groove portion 21c, and in this state, the nozzle holder 30 is pulled down, whereby the nozzle holder 30 is detached from the shaft member 20. Hereinafter, a direction of rotation (a direction opposite to the arrow b) in which the locking member 31e is caused to reach the position of the vertical groove portion 21c from the position of the horizontal groove portion 21b is referred to as a "release direction".
Next, a structure of a nozzle frame attaching/detaching device 50 used when attaching/detaching the nozzle frame 30 to/from the shaft member 20 provided in the mounting head 8 will be described with reference to fig. 6 to 7B. Fig. 7B shows a section C-C in fig. 7A. In fig. 6, a plurality of openings 50b are formed in the upper surface 50a of the nozzle rack attachment/detachment device 50, and a plurality of substantially cylindrical rack engaging portions 51 that hold the nozzle rack 30 are respectively arranged so as to protrude from the respective openings 50 b. The number and arrangement of the rack engaging portions 51 are designed in accordance with the number and arrangement of the shaft members 20 included in the mounting head 8. The suction nozzle rack attaching/detaching device 50 shown in fig. 6 to 7B has twelve rack engaging portions 51 corresponding to the mounting head 8 shown in fig. 2.
In fig. 6, a rack holding hole 51a having an upper opening is formed in the rack engaging portion 51. A pair of locking grooves 51b that extend from the holder holding hole 51a to the outside of the holder engaging portion 51 and that are open at the upper part thereof are formed at the upper part of the holder engaging portion 51. When the holder engaging portion 51 holds the nozzle holder 30, the direction of the engaging member 31e of the nozzle holder 30 is aligned with the engaging groove 51b, and the nozzle holder 30 is inserted into the holder holding hole 51a from above. The nozzle holder 30 is held by the holder engaging portion 51 in a state where the locking member 31e is locked to the bottom surface of the locking groove 51b. That is, the rack engaging portion 51 engages with the nozzle rack 30 in a state where the nozzle 40 is mounted on the nozzle rack 30. The holder holding hole 51a is formed so as to be capable of holding either the nozzle holder 30 to which the nozzle 40 is attached or the nozzle holder 30 from which the nozzle 40 is detached.
In fig. 6, two alignment pins 52 are provided on the upper surface 50a of the nozzle mount/demount device 50 so as to protrude upward, and the two alignment pins 52 are fitted into positioning holes 13a formed in the two protruding positioning portions 13 on the lower surface of the mounting head 8, respectively (see fig. 9A and 9B). By lifting the nozzle rack attachment/detachment device 50 upward from below the mounting head 8 so that the alignment pins 52 are inserted into the positioning holes 13a of the mounting head 8, the twelve nozzle racks 30 mounted on the twelve shaft members 20 can be simultaneously inserted into the rack holding holes 51a of the twelve rack engaging portions 51, respectively. Thus, the two positioning holes 13a of the mounting head 8 and the two alignment pins 52 of the nozzle rack attachment/detachment device 50 constitute alignment portions for aligning the rack engaging portions 51 with respect to the mounting head 8.
In fig. 7A and 7B, pressing members 53 are disposed on the side surfaces 50c of the nozzle rack attachment/detachment device 50. Inside the nozzle rack attachment/detachment device 50, two racks 54 extending horizontally in directions (hereinafter referred to as "left-right directions") in which the side surfaces 50c on both sides face each other are arranged. The two racks 54 are connected to the left and right pressing members 53 via connecting portions 54 b. The rack 54 is provided so as to be movable in the left-right direction in a state in which movement in the up-down direction is restricted by the sliders 55 disposed inside the front surface 50d and inside the rear surface 50e of the nozzle rack attachment/detachment device 50, respectively. When the pressing member 53 is pushed in inward or the pressing member 53 is projected outward, the rack 54 moves in the left-right direction according to the movement of the pressing member 53 (see fig. 8B and 8C).
The movement of the pressing member 53 in the outer direction is restricted by the position where the skirt 53a located inside the nozzle rack attaching/detaching device 50 of the pressing member 53 abuts against the inner side of the side surface 50 c. Hereinafter, a position at which the movement of the pressing member 53 in the outer direction is restricted is referred to as a "standby position". The inward movement of the pressing member 53 is restricted by a position where the skirt 53a abuts against a restricting plate 56 provided inside the nozzle rack attaching/detaching device 50 (see fig. 8B). Hereinafter, a position at which the movement of the pressing member 53 in the inward direction is restricted is referred to as a "maximum click position".
A coil-shaped compression spring 57 is mounted on the connecting portion 54b, and one end of the compression spring 57 is in contact with the restricting plate 56 and the other end is in contact with the inner wall 53b of the pressing member 53. That is, the pressing member 53 is biased outward by the compression spring 57. Therefore, when the pressing member 53 is pushed into the maximum push-in position from the outside and then the pressing force is removed, the pressing member 53 moves to the outside by the urging force of the compression spring 57 and returns to the standby position (see fig. 8C).
In fig. 7A and 7B, a rotation shaft 58 extending in the up-down direction is fixed to the bottom of the rack engaging portion 51. The lower side of the rotation shaft 58 is held so as to be rotatable by a bearing 59 incorporating a bearing member. A spur gear 60 is fixed to the rotation shaft 58, and teeth 60a that mesh with the teeth 54a formed on the rack 54 are formed on the outer circumference of the spur gear 60. With this configuration, when the spur gear 60 performs θ rotation, the rack engaging portion 51 fixed to the rotation shaft 58 performs θ rotation.
Next, the function of the nozzle rack attachment/detachment device 50 will be described with reference to fig. 8A to 8C. Fig. 8A to 8C schematically show the inside of the nozzle rack attaching/detaching device 50 shown in fig. 7A, and the slider 55 and the like are omitted. When the pressing members 53 on both sides are pushed inward to the maximum push-in position (arrow c) as shown in fig. 8B from the state where the pressing members 53 on both sides are located at the standby position as shown in fig. 8A, the two racks 54 are respectively moved inward (arrow d). The spur gear 60 rotates θ in the clockwise direction with the movement of the rack 54, and the rack engaging portion 51 rotates θ in the clockwise direction (arrow e) as well.
The nozzle rack attaching/detaching device 50 shown in fig. 8A to 8C designs the position of the restricting plate 56, the interval between the teeth 54a of the rack 54 and the teeth 60a of the spur gear 60, and the like so that the rack engaging portion 51 rotates by about 90 degrees in the clockwise direction when the pressing member 53 is pushed from the standby position to the maximum push-in position. In this way, the suction nozzle rack attaching/detaching device 50 can rotate the plurality (twelve) of rack engaging portions 51 all together by about 90 degrees in the clockwise direction by pushing the left and right pressing members 53 from the standby position to the maximum pushing position. The rotation angle of the rack engaging portion 51 rotated by pressing the pressing member 53 from the standby position to the maximum pressing position is freely changed according to the structures of the nozzle rack 30 and the housing member 21, and the like.
When the force pressing the pressing members 53 is relaxed from the state in which the pressing members 53 on both sides are pressed into the maximum pressing position (fig. 8B), the pressing members 53 are moved to the standby position (arrow f) by the repulsive force of the compression springs 57 as shown in fig. 8C. As the pressing member 53 moves to the standby position, the two racks 54 move in the outward direction (arrow g), respectively. As the rack 54 moves, the spur gears 60 rotate in the counterclockwise direction, and as a result, the rack engaging portions 51 rotate in the counterclockwise direction (arrow h). In this way, the suction nozzle rack attaching/detaching device 50 can rotate the plurality (twelve) of rack engaging portions 51 all together by about 90 degrees in the counterclockwise direction by returning the left and right pressing members 53 from the maximum pressing position to the standby position.
In this way, the rack 54, the rotation shaft 58, the bearing 59, and the spur gear 60 constitute a rotation mechanism section that rotates the rack engaging section 51 together. The rotation mechanism converts the pressing operation (arrow C in fig. 8B, arrow f in fig. 8C) of the pressing member 53 connected to the rack 54 into rotation. That is, the pressing member 53 is an operation portion that rotates the rack engaging portion 51 by an operation (pressing operation) of the pressing member 53.
In the above-described configuration, two pressing members 53 are provided corresponding to the left and right side surfaces 50c of the nozzle rack attachment/detachment device 50, but one pressing member 53 may be provided on each side surface 50c. In this case, the rack 54 that rotates the rack engaging portion 51 of the front row and the rack 54 that rotates the rack engaging portion 51 of the rear row are connected to one pressing member 53. That is, the pressing member 53 (operation portion) is provided at least on one side surface 50c of the nozzle rack attaching/detaching device 50. The operation unit is not limited to the pressing member 53. For example, the operation unit may be a member that reciprocates the rack 54 in the horizontal direction by a lever operation, as long as the operation unit can receive an operation from the outside.
Next, a method of attaching and detaching the nozzle holder 30 mounted on the shaft member 20 of the mounting head 8 using the nozzle holder attaching and detaching device 50 will be described with reference to fig. 9A to 12B. The mounting head 8 is moved to a position where an operator can easily work in the component mounting apparatus 1, and then the mounting head 8 is put into a state where the mounting head 8 is not operated, or the mounting head 8 is taken out from the component mounting apparatus 1 and held by a head holder (not shown), and then the nozzle holder 30 of the present embodiment is attached and detached. That is, the nozzle holder 30 is attached and detached in a state where the mounting head 8 such as the power supply is turned off and the like is not operated.
First, a process of removing the nozzle holders 30 mounted on the plurality of shaft members 20 of the mounting head 8 shown in fig. 9A will be described. In fig. 9A, the operator holds the nozzle holder attaching/detaching device 50 with one hand (not shown), and brings the nozzle holder attaching/detaching device 50 close from below the mounting head 8. At this time, the alignment pin 52 of the nozzle rack attachment/detachment device 50 is aligned with a position where the positioning hole 13a of the mounting head 8 can be inserted. Thereby, the positions of the plurality of rack engaging portions 51 are aligned with the plurality of shaft members 20 of the mounting head 8, respectively. Thus, the alignment of the rack engaging portion 51 with respect to the mounting head 8 is performed (ST 1: alignment step).
In fig. 9A, the locking members 31e of the plurality of nozzle holders 30 mounted on the shaft member 20 are oriented in the lateral direction, respectively. The pair of locking grooves 51b of the plurality of rack engaging portions 51 of the nozzle rack attaching/detaching device 50 are also oriented in the lateral direction, respectively. In fig. 9B, the worker lifts the nozzle rack attaching/detaching device 50 (arrow j 1) so that the alignment pin 52 of the nozzle rack attaching/detaching device 50 is inserted into the positioning hole 13a of the mounting head 8. Thereby, the nozzle holder 30 is inserted into the holder holding hole 51a of the holder engaging portion 51.
The worker lifts the suction nozzle rack attachment/detachment device 50 so that the locking member 31e enters the locking groove 51b and abuts against the bottom surface of the locking groove 51b, and the bottom surface of the locking groove 51b pushes up the locking member 31e to bring the suction nozzle rack 30 to the upper side. The upper portion of the positioning pin 52 and the upper portion of the positioning hole 13a are set to abut against each other in a state where the nozzle frame 30 reaches the upper side to the height. This makes it possible to easily stop the nozzle rack attachment/detachment device 50 when the upper reach height is reached.
The lower surface of the positioning portion 13 may be set to abut against the upper surface 50a of the nozzle holder attaching/detaching device 50 in a state where the nozzle holder 30 reaches the upper side. In this way, the plurality of rack engaging portions 51 can be engaged with the plurality of nozzle racks 30 mounted on the plurality of shaft members 20 of the mounting head 8 at a time (ST 2: rack engaging step).
Next, in fig. 10A, the operator presses the left and right pressing members 53 of the hand-held nozzle holder attaching/detaching device 50 to the maximum pressing position with the thumb, the little finger, or the like (arrow j 2). Thus, the plurality of rack engaging portions 51 of the nozzle rack attaching/detaching device 50 are simultaneously rotated by about 90 degrees in the clockwise direction, and the nozzle rack 30 engaged with the engaging grooves 51b of the rack engaging portions 51 by the engaging members 31e is rotated by about 90 degrees in the releasing direction. That is, the plurality of rack engaging portions 51 engaged with the nozzle rack 30 are rotated in the releasing direction at once (ST 3: rotating step). In this way, the rotation mechanism converts the pressing operation of the pressing member 53 into rotation. The rotation mechanism section rotates the plurality of rack engaging sections 51 at once. The rotation mechanism unit rotates the plurality of rack engaging portions 51 in the same direction.
Next, in fig. 10B, the operator pushes the left and right pressing members 53 to the maximum push-in position (arrow j 2) and pulls down the nozzle rack attachment/detachment device 50 (arrow j 3). Thereby, the nozzle holder 30 is disengaged from the shaft member 20 in a state held by the holder engaging portion 51. That is, after the rotation step (ST 3), the plurality of rack engaging portions 51 are separated from the mounting head 8 to collectively remove the plurality of nozzle racks 30 from the plurality of shaft members 20 (ST 4: rack removal step).
In this way, in a state where the rack engaging portion 51 is engaged with the nozzle rack 30 (ST 2), the rack engaging portion 51 is rotated by the rotation mechanism portion (the rack 54, the rotation shaft 58, the bearing 59, the spur gear 60) by the operation of the pressing member 53 (ST 3), and the nozzle rack 30 is removed from the shaft member 20. Thereby, the sliding shaft 20b of the shaft member 20 is exposed. Further, since the nozzle holder 30 is removed in a state of being accommodated in the holder engaging portion 51, the compression spring member 34 of the nozzle holder 30 can be prevented from coming off. In the head-mounted maintenance method of the present embodiment, the worker cleans the shaft member 20 from which the nozzle holder 30 is removed (ST 5: cleaning step). The shaft member 20 may be cleaned by a dedicated cleaning device.
Next, a process of mounting the nozzle holder 30 to each of the plurality of shaft members 20 included in the mounting head 8 will be described. The step of attaching the nozzle holder 30 is performed when the nozzle holder 30 detached for cleaning the shaft member 20 is attached as it is or when the nozzle holder 30 is replaced.
When the nozzle holder 30 is not present in the holder engaging portion 51 of the nozzle holder attaching/detaching device 50, such as when the nozzle holder 30 is replaced, first, the operator holds the plurality of nozzle holders 30 to be mounted on the plurality of shaft members 20 of the mounting head 8 by the plurality of holder engaging portions 51 (ST 6: holder preparation step). That is, the rack engaging portion 51 engages with the nozzle rack 30 to be mounted to the shaft member 20. At this time, the rotation direction is adjusted so that the locking member 31e of the nozzle holder 30 is inserted into the locking groove 51b of the holder engaging portion 51, whereby the nozzle holder 30 is held by the holder engaging portion 51 (see fig. 11A).
Next, in fig. 11A, the worker performs alignment so that the alignment pin 52 of the nozzle rack attachment/detachment device 50 can be inserted into the positioning hole 13a of the mounting head 8, and brings the nozzle rack attachment/detachment device 50 close to it from below the mounting head 8, as in the alignment step (ST 1). That is, in the mounting head maintenance, the alignment step (ST 1) is performed before the rack engagement step (ST 2) and before the rack attachment step (ST 7) described later.
At this time, the operator pushes the left and right pressing members 53 of the nozzle rack attachment/detachment device 50 to the maximum push-in position (arrow j 4). Thus, the plurality of rack engaging portions 51 of the nozzle rack attaching/detaching device 50 are simultaneously rotated by about 90 degrees in the clockwise direction, so that the direction of the engaging member 31e of the nozzle rack 30 coincides with the direction of the vertical groove portion 21c of the housing member 21.
Next, in fig. 11B, the operator lifts (arrow j 5) the nozzle rack attachment/detachment device 50 in a state where the pressing member 53 is pressed into the maximum pressing position (arrow j 4), and inserts the alignment pin 52 of the nozzle rack attachment/detachment device 50 into the positioning hole 13a of the mounting head 8. Thereby, the nozzle holder 30 is inserted into the shaft member 20 in a state where the locking member 31e of the nozzle holder 30 enters the vertical groove portion 21c of the housing member 21 (see fig. 5B). The operator lifts the nozzle frame attaching and detaching device 50 until the nozzle frame 30 reaches the upper reach height. Thus, the plurality of nozzle holders 30 held by the plurality of holder engaging portions 51 are collectively mounted on the plurality of shaft members 20, respectively (ST 7: holder attaching step).
Next, in fig. 12A, the operator returns the left and right pressing members 53 of the nozzle rack attachment/detachment device 50 to the standby position (arrow j 6) in a state where the nozzle rack 30 is at the upper side to the height. Accordingly, the plurality of rack engaging portions 51 of the nozzle rack attaching/detaching device 50 are simultaneously rotated by about 90 degrees in the counterclockwise direction, and the nozzle racks 30 held by the rack engaging portions 51 are rotated by about 90 degrees in the locking direction. That is, in a state where the plurality of nozzle holders 30 are mounted on the plurality of shaft members 20, the plurality of holder engaging portions 51 are rotated (counter-rotated) in a direction (locking direction) opposite to the rotating step (ST 3) at a time (ST 8: counter-rotating step).
Next, in fig. 12B, the worker pulls down the nozzle rack attachment/detachment device 50 (arrow j 7). Thereby, the locking member 31e of the nozzle holder 30 is fitted into the horizontal groove portion 21b of the housing member 21 (see also fig. 5C). In this way, the plurality of nozzle holders 30 are collectively mounted on the plurality of shaft members 20.
As described above, the nozzle rack attaching/detaching device 50 of the present embodiment includes the rack engaging portion 51 and the rotation mechanism portion (the rack 54, the rotation shaft 58, the bearing 59, and the spur gear 60) for engaging the rack engaging portion 51 with the at least one nozzle rack 30 provided in the mounting head 8. In the suction nozzle rack attaching/detaching device 50, the rack engaging portion 51 is rotated by the rotation mechanism portion in a state where the rack engaging portion 51 is engaged with the suction nozzle rack 30, so that the suction nozzle rack 30 is attached/detached to/from the mounting head 8. This allows the nozzle holder 30 to be easily attached to and detached from the mounting head 8.
Next, another embodiment of the nozzle rack attachment/detachment device (hereinafter referred to as "another nozzle rack attachment/detachment device 70") will be described with reference to fig. 13A to 14C. The other nozzle rack attachment/detachment device 70 is different from the nozzle rack attachment/detachment device 50 described above in that the rotation direction and the presence/absence of rotation of the plurality of rack engaging portions 51 can be individually selected. Hereinafter, the same parts as those of the nozzle rack attaching/detaching device 50 are denoted by the same reference numerals, and detailed description thereof will be omitted. Fig. 13B shows a section D-D in fig. 13A. The other nozzle rack attachment/detachment device 70 has twelve rack engaging portions 51 and two alignment pins 52 at the upper portion, as in the nozzle rack attachment/detachment device 50.
In fig. 13A and 13B, the pressing members 53 disposed on both side surfaces of the other nozzle rack attachment/detachment device 70 are connected to second racks 72 in addition to first racks 71 similar to the racks 54 of the nozzle rack attachment/detachment device 50. Teeth 71a and teeth 72a are formed on the opposite sides of the first rack 71 and the second rack 72, and the teeth 71a and teeth 72a mesh with teeth 73a of spur gear 73 coupled to the rack engaging portion 51. The second rack 72 is disposed opposite to the first rack 71 so as to sandwich the spur gear 73, and is disposed in parallel with the first rack 71 at a height position lower than the first rack 71. When the pressing member 53 is pushed in inward or the pressing member 53 is projected outward, the first rack 71 and the second rack 72 move in the left-right direction along with the movement of the pressing member 53 (see fig. 14B and 14C).
In fig. 13B, a spline bearing 75 is fixed to the bottom of the rack engaging portion 51, and the spline bearing 75 engages with a spline groove (not shown) formed in the upper portion of the rotation shaft 74 extending in the up-down direction to hold the rotation shaft 74 so as to be rotatable by θ. The lower side of the rotation shaft 74 passes through a bearing 76 having a bearing member built therein and holding the rotation shaft 74 rotatably, and protrudes to the outside of the lower surface 70a of the other nozzle frame attachment/detachment device 70. A grip member 77 is mounted on the lower end of the rotation shaft 74 protruding from the lower surface 70a of the other nozzle frame attachment/detachment device 70. Spur gear 73 is fixed to rotary shaft 74.
When the operator grips the grip member 77 and moves it in the up-down direction, the rotation shaft 74 moves in the up-down direction. Thereby, the spur gear 73 fixed to the rotation shaft 74 moves up and down between a height position (hereinafter referred to as "first rotation position") meshing with the first rack 71 and a height position (hereinafter referred to as "second rotation position") meshing with the second rack 72. A height difference in which the spur gear 73 can be disposed so as not to interfere with each other is provided between the first rack 71 and the second rack 72. Hereinafter, a height position at which the spur gear 73 does not interfere with the first rack 71 and the second rack 72 is referred to as a "no-rotation position".
With spur gear 73 in the first rotational position, spur gear 73 meshes with first rack 71. When the first rack 71 moves in the left-right direction in this state, the spur gear 73 rotates θ, and the rack engaging portion 51 rotates θ (first rotation direction) via the rotation shaft 74 and the spline bearing 75. With spur gear 73 in the second rotational position, spur gear 73 meshes with second rack 72. When the second rack 72 moves in the left-right direction in this state, the spur gear 73 rotates θ, and the rack engaging portion 51 rotates θ (second rotational direction) in the direction opposite to the first rotational position via the rotation shaft 74 and the spline bearing 75. In the case where the spur gear 73 is located at the non-rotation position, the spur gear 73 does not follow the movement of the first rack 71 and the second rack 72. That is, when spur gear 73 is in the non-rotating position, rack engaging portion 51 does not rotate.
In this way, the first rack 71, the second rack 72, the spur gear 73, the rotation shaft 74, the spline bearing 75, and the bearing 76 constitute a rotation mechanism portion that rotates the rack engaging portion 51. The spur gear 73, the rotation shaft 74, and the grip member 77 constitute a selection mechanism portion that selects rotation of the rack engaging portion 51 in the first rotation direction (first rotation position), non-rotation (no rotation position), and rotation in the second rotation direction (second rotation position), which is the reverse direction. That is, the rotation mechanism unit has a selection mechanism unit and functions to rotate, not rotate, or reversely rotate at least one rack engaging unit 51 selected from the plurality of rack engaging units 51.
In fig. 13B, the spur gears 73 of the rack engaging portions 51 are selected from the left to be in the first rotation position, the no rotation position, the second rotation position, the first rotation position, the no rotation position, and the second rotation position.
Next, the function of the other nozzle rack attachment/detachment device 70 will be described with reference to fig. 14A to 14C. Fig. 14A to 14C schematically show the inside of another nozzle rack attaching/detaching device 70 shown in fig. 13A. The front (six) and rear (six) rows of spur gears 73 of the plurality of rack engaging portions 51 of the other nozzle rack attaching/detaching device 70 are each selected as the positions shown in fig. 13B. When the pressing members 53 on both sides are pushed inward to the maximum push-in position (arrow k) as shown in fig. 14B from the state where the pressing members 53 on both sides are located at the standby position shown in fig. 14A, the left and right first racks 71 and the second racks 72 are moved in the inward direction (arrow m), respectively.
In fig. 14B, as the first rack 71 moves, the spur gears 73 at the first rotational positions rotate in the clockwise direction, and along with this, the rack engaging portions 51 rotate in the clockwise direction (arrow n). In addition, spur gear 73 in the non-rotation position does not rotate, and rack engaging portion 51 does not rotate. In addition, as the second rack 72 moves, the spur gears 73 located at the second rotational positions rotate θ in the counterclockwise direction, and accordingly, the rack engaging portions 51 also rotate θ in the counterclockwise direction (reverse direction) (arrow p).
When the force pressing the pressing members 53 is relaxed from the state in which the pressing members 53 on both sides are pressed into the maximum pressing position (fig. 14B), the pressing members 53 are moved to the standby position (arrow q) by the repulsive force of the compression springs 57 as shown in fig. 14C. As the pressing member 53 moves to the standby position, the left and right first racks 71 and the second racks 72 move in the outward direction, respectively (arrow r).
In fig. 14C, as the first rack 71 moves, the spur gears 73 at the first rotational positions rotate in the counterclockwise direction θ, and accordingly, the rack engaging portions 51 also rotate in the counterclockwise direction (reverse direction) (arrow s). In addition, spur gear 73 in the non-rotation position does not rotate, and rack engaging portion 51 does not rotate. In addition, as the second rack 72 moves, the spur gears 73 located at the second rotational positions are respectively rotated θ in the clockwise direction, and along with this, the rack engaging portions 51 are also rotated θ in the clockwise direction (reverse rotation) (arrow t).
The other nozzle frame attaching/detaching device 70 is used, for example, when attaching/detaching only a part of the nozzle frames 30 among the nozzle frames 30 attached to the mounting head 8 having twelve shaft members 20 shown in fig. 2. In this case, the other nozzle rack attaching/detaching device 70 is used such that the spur gear 73 of the rack engaging portion 51 corresponding to the nozzle rack 30 to be attached/detached is positioned at the first rotation position or the second rotation position, and the other spur gear 73 is positioned at the non-rotation position.
In addition, all spur gears 73 may be used in alignment with the first rotational position when the nozzle holder 30 is removed, and all spur gears 73 may be used in alignment with the second rotational position when the nozzle holder 30 is assembled. In this case, during the removal of the nozzle rack 30, the alignment step (ST 1), the rack engagement step (ST 2), the rotation step (ST 3), and the rack removal step (ST 4) shown in fig. 9A to 10B are performed. Further, at the time of assembling the nozzle rack 30, in the rack attaching step (ST 7), the pressing member 53 is performed in a state of being located at the standby position; in the reverse rotation step (ST 8), the pressing member 53 is pushed into the maximum push-in position, and the plurality of rack engaging portions 51 are rotated in the reverse direction at once. That is, the operation of the pressing member 53 in the rotation step (ST 3) and the reverse rotation step (ST 8) can be set to be the same.
When the nozzle rack 30 is attached to or detached from the plurality of shaft members 20 provided in the mounting head 8, in a case where the directions in which the nozzle rack 30 rotates are mixed, the spur gear 73 of the rack engaging portion 51 of the other nozzle rack attaching/detaching device 70 is set to the first rotation position or the second rotation position in accordance with the mounting head 8, so that the nozzle rack 30 can be attached or detached together.
The other nozzle mount/demount device 70 may be configured to select three modes of rotation, no rotation, and reverse rotation, or may be configured to select two modes of rotation and no rotation. In this case, the second rack 72 can be deleted. The suction nozzle rack attachment/detachment device 50 and the other suction nozzle rack attachment/detachment device 70 have a structure having twelve rack engaging portions 51, but the number of the rack engaging portions 51 may be freely changed according to the structure of the mounting head 8. The reverse rotation means that the rack engaging portion is reversely rotated with respect to the direction of attachment to the nozzle rack.
The suction nozzle rack attaching/detaching device and the mounting head maintenance method of the present invention have the effect of enabling the suction nozzle rack to be easily attached/detached to/from the mounting head, and are useful in the field of mounting components on a substrate.
