Embodiment
Below, with reference to accompanying drawing, execution mode of the present utility model is described.
Fig. 1 be the apparatus for mounting component that relates to of an expression execution mode of the present utility model a part, be the stereogram of the installation that possesses of apparatus for mounting component 10.
As shown in Figure 1, install 10 by X beam 12 supportings that are arranged on the apparatus for mounting component and extend along X-direction for can be mobile in X-direction.X beam 12 is can be mobile in Y direction by not shown Y beam support.By X beam 12 and Y beam, installing 10 can be mobile in X-direction and Y direction.
In addition, as shown in Figure 2, install 10 and constitute and to be divided into a pair of assembly 10a, 10b.A pair of assembly 10a, 10b are respectively roughly the same structure, and constitute being positioned at the state lower edge Y direction of inboard mode with respect to vertical guide (Z-X plane) balanced configuration with nozzle 22 and assemble mutually.Thus, can shorten spacing between the nozzle of a plurality of nozzles 22 that X-Y plane disposes, constitute compactly thereby will install 10.Need to prove that a pair of assembly 10a, 10b be identical with essence on the structure that the utility model is associated, but have nothing in common with each other in the structure that for example is used for installing a head-shield of 10 and control substrate etc. etc.
A pair of assembly 10a, 10b have respectively: frame section 14; Four nozzle units 20 from top absorption and holding member.As shown in Figure 2, frame section 14 has: three beam 14a~14c that extend parallel to each other on X-direction; The pair of side plates 14d that the two ends of three beam 14a~14c are fixing.In each assembly 10a, 10b, four nozzle units 20 being arranged in the state configuration of a row shape along X-direction, and are fixed on three beam 14a~14b between pair of side plates 14d.With reference to Fig. 1~Fig. 5, the details of this nozzle unit 20 is described.
Fig. 3 is the stereogram that takes off the installation 10 of three states behind the nozzle unit 20 from assembly 10a, 10b respectively.Fig. 4 is the stereogram of each assembly 10a, 10b nozzle unit 20 separately, and Fig. 5 installs a cutaway view of 10.
As shown in Figure 4, nozzle unit 20 has respectively: from the nozzle 22 of top absorption holding member; It is can be at the mobile slide mechanism 24 of Z-direction (vertical) that nozzle 22 is supported; Be used for making the straight-moving mechanism 26 by nozzle 22 liftings of slide mechanism 24 supportings; Be used for making nozzle 22 centered by vertical axis and the rotating mechanism 28 that is rotated.
As shown in Figures 3 and 4, the slide mechanism 24 of nozzle unit 20 comprises: along the guide rail 30 of Z-direction extension; A plurality of bootstrap block 32a, the 32b that on Z-direction, can engage with guide rail 30 movably.
As shown in Figure 5, in the bottom of the guide rail 30 of slide mechanism 24 nozzle 22 is installed.Particularly, fixedly have in the bottom at the back side of guide rail 30 (with the surface of bootstrap block 32a, 32b side opposition side) the nozzle holder 34 of nozzle 22 supportings for can centered by the rotating shaft R that extends along Z-direction, being rotated.Need to prove, be pasted with stiffener 36 at the back side of guide rail 30.The back that acts on to this stiffener 36 is narrated.
As Fig. 3 and shown in Figure 5, a side's of slide mechanism 24 bootstrap block 32a is fixed on the side of beam 14a of the upper side that 10 frame section 14 is installed.The opposing party's bootstrap block 32b is fixed on the side of beam 14b.Relative therewith, the guide rail 30 of slide mechanism 24 is not fixed on the frame section 14 of installation 10 of lower side of frame section 14.Therefore, guide rail 30 can relatively move in Z-direction with respect to 10 frame section 14 is installed.Consequently, the nozzle 22 that is installed on the guide rail 30 can relatively move in Z-direction (vertical) with respect to installing 10.
As shown in Figure 5, straight-moving mechanism 26 is so that be provided with the guide rail 30 of the slide mechanism 24 of nozzle 22 and constitute in the mobile mode of Z-direction in the bottom.For this reason, straight-moving mechanism 26 has: the straight kinetoplast 38 that is connected with guide rail 30; The motor 40 as drive source that straight kinetoplast 38 is moved along the straight moving axis L that extends in Z-direction.
The straight kinetoplast 38 of straight-moving mechanism 26 extends along Y direction to bootstrap block 32a, 32b side from the part of the guide rail 30 between two bootstrap block 32a, the 32b.
The motor 40 of straight-moving mechanism 26 is fixed on the upper surface of beam 14a of the upper side of frame section 14.Particularly, as Fig. 3 and shown in Figure 5, be formed with the through hole 14e that extends along Z-direction at beam 14a, so that the axle 40a of motor 40 is fixed on motor 40 by the mode of this through hole 14e the upper surface of beam 14a.
The straight kinetoplast 38 of straight-moving mechanism 26 links via ball screw framework 42 with motor 40.Ball screw framework 42 is made of the ballscrew shaft 42a that extends along Z-direction and the ball-screw nut 42b that engages with ballscrew shaft 42a.The axle 40a of the end of ballscrew shaft 42a and motor 40 links, and this ballscrew shaft 42a is being rotated centered by straight moving axis L under the effect of motor 40.The ball-screw nut 42b that engages with ballscrew shaft 42a is installed on straight kinetoplast 38.
According to such straight-moving mechanism 26, when ballscrew shaft 42a is rotated centered by straight moving axis L, via ball-screw nut 42b straight kinetoplast 38 is moved along straight moving axis L.Consequently, make guide rail 30 (being nozzle 22) mobile in Z-direction.
In addition, because the straight kinetoplast 38 of straight-moving mechanism 26 is installed on the part of two guide rails 30 between bootstrap block 32a, the 32b, therefore can suppress the deflection of straight-moving mechanism 26 caused guide rails 30.Use Fig. 5 describes, when making ball-screw 42a rotation make straight kinetoplast 38 when Z-direction moves by motor 40, may produce on guide rail 30 lower end side that makes guide rail 30 to the such deflection of Y direction displacement.In order to suppress this deflection, two bootstrap block 32a, 32b are disposed in the mode of the part that clips the guide rail 30 that straight kinetoplast 38 is installed in Z-direction.
In order further to suppress the deflection of straight-moving mechanism 26 caused guide rails 30, stiffener 36 is sticked on the back side of guide rail 30 of nozzle holder 34 sides of Y direction.As shown in Figure 5, stiffener 36 is crossed with the back portion of straight kinetoplast 38 opposed guide rails 30 from the lower end side of guide rail 30 and is extended.Need to prove that under the high situation of the flexural rigidity of guide rail 30, stiffener 30 can omit.
And, because straight-moving mechanism 26 is sandwiched in guide rail 30 therebetween and straight-moving mechanism 26 and these guide rail 30 disposed adjacent on Y direction with nozzle 22, therefore can reduce to install a Z-direction size of 10.
As shown in Figure 4, be used for making the rotating mechanism 28 of nozzle 22 rotations to have: spline coupling 44, it extends along Z-direction; Motor 46, it makes nozzle 22 rotations via spline coupling 44, and this nozzle 22 is remained and can be rotated centered by rotating shaft R by nozzle holder 34.
The motor 46 of rotating mechanism 28 is fixed on the upper surface of the beam 14c of frame section 14.Particularly, as Fig. 3 and shown in Figure 5, be formed with the through hole 14f that extends along Z-direction at beam 14c, so that the axle 46a of motor 46 is fixed on motor 46 by the mode of this through hole 14f the upper surface of beam 14d.
The spline coupling 44 of rotating mechanism 28 is made of with the splined shaft 44a of the axle 46a binding of motor 46 and the splined nut 44b that can engage with splined shaft 44a movably on Z-direction an end.Splined nut 48 links with nozzle 22 sides.Thus, when making splined shaft 44a rotation by motor 46, make nozzle 22 rotations via splined nut 44b.
More than, according to the installation of such structure 10, a plurality of nozzles 22 are relatively moved independently with respect to installing 10.And, a plurality of nozzles 22 are rotated centered by rotating shaft R independently.
According to present embodiment, can realize length (50~70mm) the lifting travel for example, and make simultaneously 10 densification is installed of nozzle 22.
About this effect, the installation head of enumerating comparative example describes.Fig. 6 is the cutaway view of the installation head of comparative example.
As shown in Figure 5, under the situation of the installation of present embodiment 10, be provided with nozzle 22 in the lower side of the guide rail 30 of slide mechanism 24, bootstrap block 32a, the 32b that engages with guide rail 30 is fixed in a frame section 14 of 10 is installed.In addition, the straight moving axis L of the rotating shaft R of nozzle 22 and straight kinetoplast 38 clips guide rail 30 and arranged opposite.
On the other hand, as shown in Figure 6, under the situation of the installation of comparative example 110, guide rail 130 is fixed in installs a frame section 114 of 110, at the bootstrap block 132a that engages with guide rail 130,132b side fixed nozzle 122.And, because guide rail 130 is fixed in frame section 114, therefore make the rotating shaft R of straight moving axis L and the rotating mechanism 128 that is used for making nozzle 122 rotations of the straight-moving mechanism 126 of nozzle 122 liftings be configured in the same side with respect to guide rail 130.
Need to prove that X-direction spacing and the Y direction spacing of the nozzle 22 of the installation of the X-direction spacing of the nozzle 122 of the installation of the comparative example on the X-Y plane 110 and Y direction spacing and execution mode 10 are identical.In addition, the lifting travel of nozzle 122 is identical with the lifting travel of the length of the nozzle 22 of execution mode.And straight-moving mechanism 126 and rotating mechanism 128 are identical with straight-moving mechanism 26 and the rotating mechanism 28 of execution mode.Slide mechanism 124 is except the different this point of length of guide rail 130, and is identical with the slide mechanism 24 of execution mode.
As shown in Figure 6, under the situation of the installation of comparative example 110, because nozzle 122 is more away from the guide rail 130 of sliding track mechanism 124, therefore length and the higher arm 150 of rigidity that bootstrap block 132a, 132b and nozzle holder 134 need be linked.In addition, arm 150 is for overhanging significantly downwards from bootstrap block 132b and keeping the cantilever beam shape of nozzle 122 (nozzle holder 134) by free end.Therefore, in order to ensure the positional precision of nozzle 122, arm 150 need possess high rigidity.
In addition, because the arm 150 of the high rigidity of guide rail 130 cantilever support of slide mechanism 124, therefore need the frame section 114 of the installation of fixed guide 130 110 is relatively higher make rigidly.
Like this, realize in the structure that like that guide rail of slide mechanism is fixed in the frame section that head is installed by comparative example can causing the long installation head of lifting travel of nozzle to maximize under the situation of the lifting travel of spacing (X-direction and Y direction spacing) and nozzle between the nozzle identical with the installation of execution mode 10.
Therefore, if a plurality of bootstrap block 32a, the 32b that will engage with guide rail 30 are fixed in a frame section 14 of 10 is installed, and the straight moving axis L of the rotating shaft R of nozzle 22 and arm 38 is sandwiched in guide rail 30 therebetween and the installation of the present embodiment of arranged opposite 10, then can realize the lifting travel of the length of nozzle 22, and make installation 10 densification simultaneously.
In addition, the apparatus for mounting component owing to can realize that possesses the installation 10 of densification is installed a high-speed mobile of 10, can realize that therefore the high speed of parts is installed.
And, shown in present embodiment, installing under 10 situation that a plurality of nozzles 22 (nozzle unit 20) are arranged with the state that is arranged in two row, as shown in Figure 2, constitute and to be divided into the assembly 10a that keeps a row nozzle unit 20 and the assembly 10b of another row nozzle unit 20 of maintenance if will install 10,10 maintenance then can easily be installed.
More than, enumerate above-mentioned execution mode the utility model be illustrated, but the utility model unqualified be above-mentioned execution mode.
For example, under the situation of the installation of above-mentioned execution mode 10, constitute a plurality of nozzles 22 (nozzle unit 20) are carried with the states that are arranged in two row in Y direction, but the utility model is not limited to this.The utility model for example can be the installation head that a plurality of nozzle units are carried with the state that is arranged in a row shape, perhaps for carrying the installation head of a nozzle unit at least.
In addition, under the situation of the installation of above-mentioned execution mode 10, the guide rail 30 of slide mechanism 24 is made of straight kinetoplast 38, motor 40, ball screw framework 42 at the mobile straight-moving mechanism 26 of vertical (Z-direction).But also can replace in this, and the straight kinetoplast that is extended by the guide rail 30 from slide mechanism 24, make straight kinetoplast at the straight-moving mechanism of formations such as the mobile cylinder of vertical (Z-direction) or linear motor based on linear-motion actuator work.
And, under the situation of the installation of execution mode 10, as shown in Figure 4, be respectively equipped with motor 46 at nozzle unit 20 and be used as drive source that nozzle 22 is rotated centered by rotating shaft R.But also can replace in this, will be used to the actuator sharing of the drive source of nozzle 22 rotation that makes a plurality of nozzle units 22.
Fig. 7 represents the assembly 10a ' with the installation head of the mode after installation 10 improvement of above-mentioned execution mode.In addition, Fig. 8 is the vertical view of assembly 10a ' shown in Figure 7.Need to prove, to the inscape mark prosign identical with the installation of above-mentioned execution mode 10.
As shown in Figures 7 and 8, link the driving that is useful on nozzle 22 rotations in the upper end of the splined shaft 44a of nozzle unit 20 ' spline coupling 44 separately with belt wheel 60.A plurality of drivings are configured in respectively on the beam 14c of frame section 14 with belt wheel 60, and a plurality of driving is put on the shelf with belt wheel 60 and is provided with rotating band 62.
In addition, with belt wheel 60 bindings motor 46 ' is arranged a driving.And, in order to keep rotating band 62 and to drive with the contacting of belt wheel 60, the tensioning usefulness belt wheel 64 that rotating band 62 is applied tension force is set.
According to such structure, for example by a motor 46 ' a plurality of drivings are rotated synchronously with belt wheel 60, can a plurality of nozzles 22 be rotated synchronously via spline coupling 44 thus, thereby can constitute light-weighted installation head more compactly.
[industrial applicibility]
The utility model then just can be suitable for so long as be equipped with the installation head of at least one nozzle of absorption holding member.
