BACKGROUND OF THE INVENTION
The present invention relates to an electronic component misalignment correction apparatus provided in an electronic component mounting apparatus for mounting an electronic component on a substrate.
[0002]
[Prior art]
As an electronic component mounting device, an electronic component provided in an electronic component supply unit such as a wafer is transferred to a misalignment correction device, and the misalignment correction device presses the misalignment correction claw against the electronic component to correct the misalignment of the electronic component. It is known that after correction, an electronic component is picked up by a transfer head and mounted on a substrate such as a printed circuit board or a lead frame (for example, JP-A-4-226099).
[0003]
FIG. 8 is an exploded perspective view of a conventional electronic component misalignment correction apparatus, in which a base 1, a disk-shaped stage plate 3 disposed in a circular groove 2 on the base 1, and a stage plate 4 includes a square presser plate 4 for pressing and fixing 3 on the base 1 and a misalignment correction claw (not shown) disposed on the stage plate 3. An opening 4a for exposing the stage plate 3 is widely opened at the center of the presser plate 4, and a minute suction for semi-fixing the electronic component lightly by vacuum suction is provided at the center of the stage plate 3. A large number of holes 6 are formed. Reference numeral 5 denotes an area where the suction holes 6 are formed. A suction hole 7 for vacuum suction of the suction hole 6 is formed in the base 1. Then, the electronic component transferred onto the suction hole 6 of the stage plate 3 is lightly vacuum-sucked by the suction hole 6 so that the electronic component is not unnecessarily fluctuated, and the misalignment correction claw is pressed against the electronic component. The position deviation is corrected. The holding plate 4 that holds and fixes the stage plate 3 is a quadrangular plate, and four screws 9 are inserted into screw insertion holes 8 formed at the four corners of the holding plate 4. It was designed to be screwed into the hole 10.
[0004]
[Problems to be solved by the invention]
When the type of electronic component is changed, the stage plate 3 is replaced. Conventionally, the stage plate 3 is exchanged by removing four screws 9 and removing the holding plate 4 from the base 1, removing the stage plate 3 from the base 1, and then attaching a new stage plate 3 to the base 1. The presser plate 4 is put on the cover, and four screws 9 are screwed into the holes 8 at the four corners of the presser plate 4 so that the stage plate 3 and the presser plate 4 are placed on the base 1. It was stuck.
[0005]
However, in the conventional configuration, in order to replace the stage plate 3, four screws 9 must be attached and detached. In particular, screw insertion holes 8 opened at four corners of the presser plate 4 are provided on the base. Since the presser plate 4 must be aligned so as to match the one screw hole 10, the replacement of the stage plate 3 requires a lot of labor and time. Further, in order to adapt the direction of the formation area 5 of the suction hole 6 to the electronic component, it is necessary to set the direction of the horizontal rotation direction of the stage plate 3 to the correct direction. However, the stage plate 3 is disc-shaped and circular. Since it can rotate freely in the groove 2, it takes a lot of time and effort to set the direction correctly.
[0006]
Therefore, an object of the present invention is to provide an electronic component misalignment correction apparatus that can easily and quickly replace a stage plate.
[0007]
[Means for Solving the Problems]
The present invention relates to an electronic component misalignment correction device that corrects misalignment of an electronic component by pressing a misalignment correction claw against the electronic component, wherein a suction hole is formed on the upper surface, and a guide portion is provided on the side of the suction hole. A formed base, a stage plate formed with a suction hole and having a flange projecting at a lower portion thereof, guided by a side end by the guide portion, and slidably mounted on the base; and the base A stopper protruding from the upper surface end of the base for restricting the insertion position of the stage plate, a side member mounted on the side surface of the base, and a side member for mounting the side member on the side surface of the base and a screw means, said flange portion projecting from the first projecting portion for pressing the, also tapered surface formed on the base sides at the bottom of the side members of the upper to the stage plate of the side member A second protrusion having a tapered surface that abuts against the screw; By advancing against the base of the side member by operating the stage, the stage plate holding-down a side edge of the stage plate in the first projection so as to fix on the base The electronic component misalignment correction apparatus is characterized by the above.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
(Embodiment 1)
1 is a perspective view of an electronic component misalignment correction apparatus according to Embodiment 1 of the present invention, FIG. 2 is an exploded perspective view thereof, FIG. 3 is a sectional view thereof, and FIG. 4 is a partial sectional view thereof.
[0012]
1 and 2, a suction hole 12 is opened at the center of the upper surface of the base 11. Further, guide portions 13 are formed in a straight rib shape on both sides of the upper surface on the side of the suction hole 12. The stage plate 14 is a quadrangular plate body, and a flange portion 15 projects from the lower portion thereof, and a number of minute suction holes 16 are formed at the center portion thereof. Reference numeral 17 denotes an area where the suction holes 16 are formed. A pin-shaped stopper 18 for restricting the insertion position of the stage plate 14 protrudes from the upper end of the base 11.
[0013]
Side members 20 are mounted on both side surfaces of the base 11. The side member 20 is a plate-like body, and a first protrusion 21 protrudes from an upper part thereof, and a second protrusion 22 protrudes from a lower part thereof. The upper surface of the second protrusion 22 is a tapered surface a having a downward slope toward the inside. Further, an upwardly inclined taper surface b is formed on the side surface of the base 11 so as to be directed outwardly in contact with the taper surface a.
[0014]
A vertical screw insertion hole 23 is formed in the center of the side member 20. A screw hole 24 is formed on the side surface of the base 11. Reference numeral 25 denotes a screw which is fixed to the enormous portion 26, and a handle 27 is coupled to the enormous portion 26, and these constitute screw means. The side member 20 is applied to the side surface of the base 11, and is attached to the base 11 by inserting a screw 25 into the screw insertion hole 23 and screwing into the screw hole 24. In this case, since the screw insertion hole 23 has a vertical length, the side member 20 can move up and down slightly relative to the base 11.
[0015]
In FIG. 1, reference numeral 28 denotes a misalignment correction claw whose plane shape is a key shape, and is disposed on the stage plate 14. An electronic component is transferred onto the stage plate 14 by a transfer head. The position deviation correction claw 28 slides on the stage plate 14 and corrects the position deviation of the electronic component by pressing the inner corner portion 28a against the corner portion of the electronic component. The electronic component whose positional deviation is corrected is picked up by the transfer head and mounted on the substrate.
[0016]
This electronic component misregistration correction apparatus has the above-described configuration, and then shows a method of replacing the stage plate 14. 1 and 3 show a state in which the stage plate 14 is assembled on the base 11. As shown in the drawing, the stage plate 14 is mounted between the guide portions 13 on the upper surface of the base 11, and the collar portion 15 is pressed by the first protrusion 21 of the side member 20.
[0017]
Now, when exchanging the stage plate 14 for changing the type of electronic component, etc., the handle 27 is rotated to loosen the screw 25 and slightly remove it from the screw hole 24. In this case, the screw 25 does not have to be completely extracted from the screw hole 24, and may be extracted to such an extent that the side member 20 can be slightly moved up and down in the vertical direction. In FIG. 3, the side member 20 indicated by a chain line shows a state in which the screw 25 is loosened and slightly pulled out so that the side member 20 is slightly movable up and down in the vertical direction and is slightly removed from the base 11. Since the side member 20 is mounted on the side surface of the base 11 by inserting the screw 25 into the vertical insertion hole 23, if the screw 25 is loosened, the side member 20 can move up and down slightly.
[0018]
When the screw 25 is loosened and the side member 20 can be moved up and down in this way, the pressing state of the flange portion 15 by the first protrusion 21 is released. Therefore, the operator slides out the stage plate 14 from the base 11 (see arrow A in FIG. 1).
[0019]
Next, the operator mounts a new stage plate 14 on the base 11. FIG. 4 shows this mounting method. An operator holds a new stage plate 14 in his / her hand and slides it onto the base 11 (see arrow B). In this case, the side member 20 can swing freely in the vertical direction. Therefore, when the stage plate 14 is inserted on the upper surface of the base 11, the first protrusion 21 is slightly pushed up by the collar 15 (arrow) C)), the stage plate 14 can be inserted on the upper surface of the base 11 without difficulty. In this case, if a tapered notch 29 having an upward slope is formed on the lower surface of the insertion side end of the stage plate 14 of the first protrusion 21, the edge 30 of the collar 15 is formed. The taper-shaped notch 29 can be inserted smoothly while being guided. The stage plate 14 is inserted until the end surface of the stage plate 14 contacts the stopper 18.
[0020]
When the stage plate 14 is inserted onto the base 11 as described above, the handle 27 is rotated in the direction opposite to the previous direction, and the screw 25 is screwed into the screw hole 24. Then, the side member 20 is pushed by the end surface of the enormous portion 26 and slightly advances toward the side surface of the base 11 (arrow D in FIG. 3). Then, the taper surface a of the second protrusion 22 is slightly pushed down while abutting the taper surface b of the base 11, so that the side member 20 is also pushed down (arrow E). The stage 15 is firmly fixed on the base 11 by pressing the portion 15 firmly. The exchange of the stage plate 14 is thus completed.
[0021]
Here, the stage plate 14 is a quadrangular plate and has a linear side end face 31 (FIG. 2). The side end surface 31 is in sliding contact with the inner surface 32 (FIG. 2) of the guide portion 13, and the stage plate 14 is positioned between the guide portion 13 and the guide portion 13. Therefore, unlike the conventional example shown in FIG. 8, there is no need to perform the positioning operation in the rotational direction of the stage plate 14, and the formation area 17 of the suction holes 16 can be set in the correct orientation.
[0022]
(Embodiment 2)
5 is a perspective view of an electronic component misalignment correction apparatus according to Embodiment 2 of the present invention, FIG. 6 is an exploded perspective view thereof, and FIG. 7 is a perspective view in use.
[0023]
5 and 6, a suction hole 42 is formed at the center of the upper surface of the table-shaped base 41, and a linear guide part 43 is formed at the side of the suction hole 42. The inner surface of the guide portion 43 is a wedge-shaped tapered surface 44. A screw hole 45 is formed in the end surface of the base 41, and a stopper 46 projects from the upper surface end of the base 41.
[0024]
A first protrusion 51 and a second protrusion 52 protrude from the upper and lower portions of the side member 50, and the upper surface of the second protrusion 52 is a tapered surface a. Further, the lower surface of the side end portion of the base 41 is also a tapered surface b. Further, the end portion of the first protrusion 51 on the insertion side of the stage plate 14 is also formed with a tapered notch 56 similar to the notch 29 in FIG. The side member 50 is formed with a vertical screw insertion hole 53 into which a screw 54 is inserted. Reference numeral 55 denotes an operator for the screw 54.
[0025]
The method for exchanging the stage plate 14 in the second embodiment is the same as that in the first embodiment. The stage plate 14 is attached to the base 41 after the screws 54 are loosened to allow the side member 50 to move up and down. Pull out from the top (arrow A in FIG. 7). Next, a new stage plate 14 is inserted (arrow B). At this time, the side member 50 is slightly pushed up by the flange portion 15 (arrow C in FIG. 5). If the stage plate 14 is inserted until it hits the stopper 46, the screw 54 is screwed into the screw hole 45. Then, the side member 50 is pushed down by the action of the tapered surfaces a and b, and the first protrusion 51 firmly presses the collar portion 15 to fix the stage plate 14.
[0026]
FIG. 7 shows a state in which the positional deviation correction of the electronic component is performed by this positional deviation correction apparatus. In the figure, 60 is an electronic component transferred on the stage plate 14, and 61 is a misalignment correction claw. In a state where the electronic component 60 is lightly vacuum-sucked by the suction hole 16 and is semi-fixed, the displacement correction claw 61 is slid to press the inner corner 62 against the corner of the electronic component 60 to correct the displacement.
[0027]
As described above, when the type of the electronic component 60 is changed, the stage plate 14 is replaced. However, since the stage plate 14 can be replaced by sliding in the directions of arrows A and B, the stage plate 14 It is not necessary to remove the misalignment correction claw 61 from the misalignment correction device when exchanging, and this is also superior to the conventional example shown in FIG. Of course, in the first embodiment, the misalignment correction claw 28 does not have to be removed when the stage plate 14 is replaced.
[0028]
【The invention's effect】
As described above, according to the present invention, the stage plate can be easily and quickly replaced.
