Description

[Detailed Description of the Invention] The present invention relates to a stage, and particularly to a stage for placing a workpiece in laser trimming or the like.

Conventionally, in laser trimming or the like, a substrate to be trimmed has been placed on an air suction type stage as shown in FIG.

That is, it is composed of a positioning guide 1, a mounting plate 4 with suction holes 3 for air suction of the substrate 2, and a pedestal 5 that is in close contact with the substrate 2, and an air hose 6 for suction.
A structure was used in which a toggle switch 7 was further provided to open and close the air.

In this structure, the trimming time per substrate is
Most of the time is occupied by the time required for moving back and forth from the board loading/unloading position to the trimming position, and the time required for loading/unloading the board.

On the other hand, in recent years, one-tray type mounting stands have appeared on which a plurality of substrates can be placed simultaneously.

With this method, multiple substrates can be processed continuously by repeating step operations in the X and Y directions, so the time required to move the stage can be minimized, and the trimming time per substrate can actually be shortened. Efforts have been made to achieve this.

However, in such a method and structure, as the number of substrates increases, the suction force due to air becomes a problem, and furthermore, the air hose becomes thicker, which has the disadvantage that it greatly impedes the stepping operation of the stage.

The purpose of this invention is to eliminate such conventional drawbacks,
In the one-tray type that can hold multiple boards at the same time,
The plurality of substrates can be positioned and fixed at once, and further,
The present invention provides a novel one-type exchangeable tray type tray with excellent operability, which allows the exchange of the tray (see Fig. 2), significantly shortens the total time for trimming, etc.

Hereinafter, one embodiment will be described in detail.

The exchange tray one-type stage of the present invention is composed of the exchange tray shown in FIG. 2 and the mount shown in FIG. 3.

First, the exchange tray will be explained.

Reference numeral 8 designates a tray-type loading plate, 9 a slide plate movable in the horizontal direction, 10 a slide plate movable in the vertical direction, and 11 a plate that can be used as an exchangeable connecting portion and a recessed portion.

In order to accurately position the board 2 when it is placed on the one-tray type mounting plate 8, two wires are placed at right angles to one corner of the board for each block on which one board is placed. Four dowel pins 15 are set up on the loading plate 8.

That is, four times as many knock pins as the number of boards to be mounted are set up on the mounting plate 8.

Further, a plate spring 13 for fixing the substrate is attached to the mounting plate 8.
so that a can move in the horizontal direction and the leaf spring 13b can move in the vertical direction.

Drill two rectangular holes (12a and 12

The slide plate 9, which is movable laterally, has a rectangular hole 12a in the mounting plate 8, in order to fix the substrate 2 placed on the mounting plate 8 placed on the upper part of the slide plate 9 from the lateral direction. A leaf spring 13a is screwed to a portion corresponding to a certain position.

Further, in order to make the slide plate 9 movable, two coil springs 14a are attached to one end of the slide plate.

Similarly, the vertically movable slide plate 10 has a plate spring attached to a portion corresponding to the position of the elongated hole 12b of the slide plate 9 placed on the slide plate 9 and the elongated hole 12b of the loading plate 8 placed further above the slide plate 10. 13b is screwed.

Note that the slide plates 9 and 10 are provided with a gap, as shown in FIG. In either case, the leaf spring on the lower slide plate can pass through the upper slide plate.

In order to move the slide plate 10, two coil springs 14b are attached to one end of the slide plate 10.

Next, a description will be given of the plate 11 that will serve as the concave portion of the re-exchange connecting portion.

The cam 16a is installed in a recess at the left end of the plate 11 (see Figure 2), the cam 16b is installed in a recess at the front end of the plate 110 (see Figure 2), and the cores at the tips of 16a and 16b are embedded in the plate 11. ing.

The cam 16a is for moving the slide plate 9 laterally.

When the tray is assembled, the curved portion 24a of the cam 16a
is coupled to a protrusion 26a attached to the end of the slide plate 9 opposite to the coil spring 14a.

The cam 14b is for moving the slide plate 10 in the vertical direction.

When the tray is assembled, the curved portion 24b of the cam 16b
is coupled to a protrusion 26b attached to the end of the slide plate 10 opposite to the coil spring 14b.

Details of the cam are shown in Figure 4. The cam consists of a knob, a cam part, and a core.

The cam portion has a smooth curve according to the angular displacement from the position 25a to the position 25b.

Slide plate 9 and cam 16b coupled to cam 16a
The slide plate 10 coupled to the slide plate 10 moves smoothly according to the cam curve due to the rotation of the cam.

The slide plate has two stationary points 2 at the beginning and end of the cam rotation.
It has two stationary points corresponding to 5a and 25b.

At the center of the bottom of the plate 11 are two rails 18 whose sides C and d are tapered in the horizontal and vertical directions.
and stopper 1 which forms a U-shape together with this rail 18.
7 is fixed.

The outer end surface of the rail is wide at the front side of the figure and narrower at the back, and the cross section of the rail is trapezoidal, with side C
The portions d and d form slopes.

The mount has a convex re-exchange coupling part 21 as shown in FIG.
It consists of a plate 22 having a stopper 20 and a magnetic chuck 19 on its upper surface, and a stand 33 fixed to the bottom surface of this plate 22.

The convex re-exchange coupling part 21 is fixed to the central part of the plate 22, and has tapered sides e and f facing sides C and d of the rail 18.

That is, the inner end surface of 21 is narrower at the front and wider at the back.

Further, the cross section of the rail is an inverted trapezoid, and the portions corresponding to planes e and f are sloped.

It is located on the upper surface of the plate 22 and is fixed to form a U-shape with the plate 21.

20 is a stopper for the tray on the mount side;
The tray is positioned together with a stopper 17 on the tray side.

Magnetic chucks 19 are attached to both ends of the stopper 20 to suction and fix the stopper 17 when the tray is inserted into the mount.

By assembling each of the parts described above, the stage of the present invention is completed. That is, the slide plate 10 (or 9), the slide plate 9 (or 10), and the stage plate 8 are stacked one after another on the plate 11. Plate 11 and rail 18 and convex re-exchange joint part 2

FIG. 5 is an assembly diagram of a one-tray type stage according to an embodiment of the present invention, and is capable of mounting 20 substrates.

In order to insert the cams 16a and 16b into the board, first
are sequentially rotated to the left and stopped when the leaf springs 13a and 13b are at their maximum distance from the knock pin 15.

Next, after inserting the board into the tray, the cams 16a, 16
When b is slowly rotated clockwise one after another, the leaf springs 13a,
13b slides toward the board and stops in such a way as to hold the board against the dowel pin.

At this time, the board is fixed by the force of the coil spring and plate spring attached to the slide plate 9 or 10.

With this single-tray structure using leaf springs,
20 boards can be smoothly positioned and fixed at once.

After inserting the board, the exchange tray is firmly fixed to the mount by slidingly pressing it against the mount 22 from the front.

At this time, the tray has a tapered rail 18 and a convex convertible coupling portion 21 . By the stoppers 17 and 20,
Positioned with high precision.

Further, the tray is securely fixed to the mount by the magnetic chuck 19.

As explained above, according to the present invention, there is no need to press the board against the positioning corner and apply air suction each time the board is inserted, unlike the conventional air suction type stage, and the plate spring is used. Due to the smooth movement of the board, all the positioning and fixing of multiple boards can be easily done in one or two steps.

At the same time, when compared with the conventional stage, problems such as problems caused by air hoses can be avoided, and a vacuum pump for suction is not required.

Furthermore, according to the present invention, in the case of laser trimming, etc., unlike conventional workpiece stands, it is possible to fix multiple substrates at the same time, and by using repeated step movements of the workpiece stand, a small number of substrates can be fixed at the same time. Multiple substrates can be trimmed by moving the stage.

That is, a plurality of substrates can be successively trimmed with one reciprocation on one stage.

Therefore, unlike the conventional method, it is no longer necessary to move the stage for each substrate, and the total trimming time can be shortened.

In addition, according to the present invention, since trays can be easily replaced, by using two trays, it is possible to load and unload substrates on one tray while trimming on the other, and the time required for loading and unloading substrates can be saved. can save a lot.

Therefore, as is clear from the above two points, according to the present invention, the total trimming time per substrate can be significantly shortened.

In addition, in terms of the operability of the present invention, simultaneous fixing of multiple boards can be done in 1 or 2 times, making the work easier.
Operation is easy.

In addition, when exchanging trays, if a side table for trays is provided on the operation console so that two trays can be taken in and out alternately, the operability of exchanging the trays will be improved.
