Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an X-Y chiffle equipped with a positioning support device, and in particular, to an This is suitable for use in a device in which an object supported by the positioning support mechanism is processed in the y@ number.

<Prior art> Two mechanisms for positioning and supporting workpieces or jigs are provided on an X-Y table, and the workpieces or parts supported by these positioning mechanisms are alternately processed or attached for assembly. There are things to do. In this case, data for driving the motor of the X-Y positioning support mechanism is required for each positioning support mechanism. - Processing and assembly work was performed using Y-table movement data.

FIG. 2 is a perspective view showing the main parts of a conventional X-Y table provided with two positioning support parts, where l is a workpiece and 2 is a jig stand for mounting the workpiece 1. .

The jig table 2 is provided with a plurality of positioning pins 3 for positioning the workpiece 1, and these positioning pins 3 are fitted into positioning holes (not shown) formed in the workpiece 1. The work l is then positioned. Reference numeral 4 denotes a jig stand mounting block, and this jig stand mounting block 4 is provided to attach the jig stand 2 to the X table 5 and to determine the height at which the work 1 is supported. There is.

Reference numeral 7 denotes a lens of a laser welding machine (not shown), and a laser beam is applied to the welding point of the workpiece 1 through this lens 7 to perform welding. The X tiple 5 and the Y table 6 are moved in the X direction and the Y direction as shown by the arrows by the X tiple motor 5a and the Y tiple motor 6a.

When using the X-Y table configured in this manner, first, the positioning hole of the workpiece 1 is manually fitted into the positioning bin 3 on the jig table 2 described above, and the workpiece 1 is placed on the jig table 2. Seraize on top. The welding point of the first workpiece 1 (for example, the workpiece on the right side) is moved to the first welding point of the first workpiece 1 (for example, the workpiece on the right side), or just below the lens, by the merging operation of the respective chifurels 5 and 6. When this movement is completed, a movement completion signal is sent to an operating section (not shown) of the laser welding machine, the laser welding machine is operated, and the welding point is irradiated with laser light from the lens 7.

As shown in the perspective view of the third space, the workpiece 1 has one or more laser welding points 1a, and after welding of the first laser welding point 1a is completed, the merging operation of the It is moved to the next laser welding point 1a or just below the lens 7.

In this way, each laser welding point 1a is sequentially moved directly below the lens 7 and the above laser welding is repeated, thereby performing the necessary welding on all the laser welding points 1a. When the laser welding of the first work l is completed, the X table 5 and the Y table 6 are exchanged and moved, and the second work l (the work on the left) is moved directly below the lens 7. Laser welding is performed similarly to the first workpiece 1 described above. and,
When all of the laser welding points 1a of the second workpiece 1 are laser welded, the X table 5 and the Y chief fluro move to the jig table 2 or the operator 8 side (see Fig. 2) by the merging operation.
Stops at the travel limit position. After stopping, the workpiece 1, which has been welded by one person, is removed from the jig table 2, and the unwelded workpiece L is fitted again into the positioning pin 3 on the jig table 2, and the series of welding operations as described above are performed. Repeat. In this manner, by setting two workpieces 1 at a time, the time required for attaching and removing the workpieces 1 is shortened, and processing efficiency is improved.

<Problem to be solved by the invention> However, in the device described above, considering the moving speed of the X-Y chifurs 5 and 6,
It takes about 5 seconds (rope ink time) to start welding the second workpiece 1 after welding is completed.

In addition, the time required to weld the two workpieces 1 together and move the X-Y chiffle to the operator side, and the time required to move the unwelded workpiece l set on the jig table 2 to the welding position t. It takes about 15 seconds in total to move it. However, since such movements that are not directly related to the actual welding operation take a lot of time, there is a problem with productivity.

Furthermore, since the x-y table must have point data for each work 1 positioned at different positions, it must have movement data for two pieces in total. For this reason, when a problem occurs, the amount of teaching (point teaching work) will be two times, so there is a problem in that it takes a lot of time to restore normality.

In view of the above-mentioned problems, the present invention aims to shorten the time required for one machining operation by reducing the wasteful movement time of the workpiece, and to shorten the recovery time when a draft occurs. With the goal.

<Means for solving the problem> The X-Y chiffle equipped with the positioning support device of the present invention is
An X-Y system used to move a work jig or workpiece positioning support mechanism in the X and Y directions in a horizontal plane and assemble or process the parts or workpieces positioned by the positioning support mechanism. In the table, a moving slide mechanism that reciprocates a support plate provided parallel to the X-Y chiffle within a horizontal plane by a predetermined range along one direction; and a movement slide mechanism provided on the support plate; a pair of parallel slide mechanisms that are reciprocated in one direction by the moving slide mechanism and that reciprocate the positioning mechanism in another direction orthogonal to the one direction; The interval and the movement stroke of the movement slide mechanism are set to be the same.

<Operation> Since the spacing between the two positioning support mechanisms that are reciprocated in the other direction by the pair of parallel slide mechanisms and the movement stroke of the moving slide mechanism are the same, the above-mentioned moving slide mechanism is By operating it, it becomes possible to selectively position the workpiece set in the first positioning support mechanism and the workpiece set in the second positioning support mechanism at a predetermined position.

As a result, the X-Y table can be made to perform only a predetermined machining operation, and the same operation can be performed for any workpiece, whether it is a workpiece that is positioned and supported at the predetermined position. You only need one piece of data. Furthermore, since one workpiece can be replaced while the other workpiece is being processed, the working time can be shortened.

<Embodiment> FIG. 1 is a perspective view of essential parts of an X-Y chiffle equipped with a positioning support device showing an embodiment of the present invention. In addition, the first
In the figures, parts that are the same as those in the prior art are designated by the same reference numerals and detailed explanations will be omitted.

As shown in FIG.
It is set to 0. This sliding rodless cylinder 10 is provided on the first joint plate I11, and the first joint plate 11 is parallel to the sliding direction of this sliding rodless cylinder 0 or the X-axis direction. It is installed on the X Chiful 5 in this way.

Next, 12 is a rodless cylinder for the parallel slide mechanism in FIG. 1, 13 is a rodless cylinder for the second parallel slide mechanism, and these two rodless cylinders 1
2.13 are mounted in parallel on the second joint plate 14. These rodless cylinders 12 and 13 are called a shuttle mechanism because they are set to alternately move back and forth along the small Y-axis direction as indicated by arrows Y-Yl.

The second joint plate 14 is aligned with the first parallel slide mechanism rodless cylinder 12 and the second parallel slide mechanism rodless cylinder 3 axis or Y axis, and slides l~ It is attached to the sliding part of the sushi linter IO.

15 and 16 are the first cylinders moved along the Y axis by the first parallel slide mechanism rodless cylinder 12 and the second parallel slide mechanism rodless cylinder 13.
．． There is a second jig table, each of which can hold one work piece! Has a feminine side.

Furthermore, a plurality of positioning pins 3 (two in the illustrated example) are protruded from each female surface of the first and second jig stands 15, 16. Reference numerals 17 and 18 denote first and second sensors for detecting the presence or absence of the workpiece 1 positioned on the respective jig stands 15 and 16. These sensors 17 and 18 are provided to prevent so-called blank welding, in which laser light is emitted even though the workpiece 1 is not set.

Movement stroke S of the slide rodless cylinder 10
is the rotorless cylinder 12 for the first parallel slide mechanism.
and second parallel slide mechanism rodless cylinder 1
It is set to be the same as the arrangement interval P of No. 3.

Furthermore, the movement stroke S of these rodless cylinders 12 and 13 for the parallel slide mechanism is set so that when one of the workpieces l is being welded, the other workpiece l can escape to a safe position. In this embodiment, it is set to, for example, 200■.

Next, the operation of the XY table equipped with the positioning support device of the embodiment configured as described above will be explained.

First, the workpiece 1 is manually set on the first jig stand 15, and a first start switch (not shown) is pressed.

As a result, the first parallel slide mechanism rotless cylinder 12 operates, and the first jig table 15 moves from the two-dot chain line position n to the solid line position in FIG. When the movement is completed, an auto switch for the first parallel slide mechanism rotless cylinder 12 (not shown) is turned on, and a movement completion signal is sent to the controller (not shown). Furthermore,
At this time, the first sensor 17 determines whether or not the work 1 is present, and if there is no work 1 on the first jig stand 15, the first parallel slide mechanism rotless cylinder]
2 is returned to the set position of work 1 and waits for restart.

In addition, if there is workpiece 1 on the first jig stand 15,
The X-table 5 and Y-table 5 and Y-table 6 each perform a predetermined movement operation, and by the merging operation of these X-table 5 and Y-table 6, the laser welding point of the workpiece 1 [A] is sequentially moved directly below the lens 7 as described above. Laser welding is then performed.

Meanwhile, on the first jig table 15! While sequentially laser welding the laser welding points 1a of the placed workpieces, an unwelded workpiece l is set on the second jig table 16,
Press the second start switch. This allows the second
The parallel slide mechanism slotless cylinder I3 operates, and the second jig table 16 moves from the position indicated by the two-dot chain line to the position indicated by the solid line in the figure. Along with this movement, the presence or absence of the workpiece l is determined by the sensor 18 as described above, and if it is determined that there is a workpiece l, the machining of the workpiece 1 on the first jig table 15 is continued until the processing is completed. stand by.

When all the welding of the workpiece 1 set on the first jig table 15 is completed, the return operation of the parallel slide mechanism parallel slide mechanism rodless cylinder 12 of $1 is started, and the first jig table 1
5 is moved from the solid line position to the two-dot chain line position. At this time, the sliding rotless cylinder 10 operates at the same time, and the second joint plate 14 moves 2 times from the solid line position.
It can be moved to the dot-dashed line position. In this case, the movement stroke S of the second joint plate 14, :It3 condition I5. Since the arrangement interval P of +6 is the same, by this movement, the workpiece 1 set on the second jig table 15
The workpiece 1 is moved directly below the lens 7, and the workpiece 1 becomes ready for welding.

and sends a movement completion signal to the controller. When this signal is given, the controller will Y
By operating the defluro and merging the operations of these chifurs, the work l on the second jig table 16 becomes
The laser welding point)-1a is sequentially moved to a predetermined welding position, and the same laser welding as described above is performed.

In this way, while the workpiece 1 on the second jig table 16 is being laser welded, the first jig table 15 is moved to the replacement position where the operator is waiting, and Another work l is set. After being set, when the above-mentioned switch is pressed, the first parallel slide mechanism mouthless cylinder 12 operates again, and the same operation as described above is repeated.

The x-y table equipped with the positioning support device of the embodiment is as follows:
Laser welding and attachment/detachment of the workpiece 1 by the worker are performed in this way, so while one workpiece 1 is being welded, the other workpiece l must be moved from the welding position l to the attachment/detachment position. At the same time, the newly set unwelded work l is attached/
It can be moved up to the limit of movement on the opposite side from the removal position. Therefore, the time required for movement not directly related to welding can be significantly reduced, and the total time required to weld one workpiece 1 can be reduced to the time required to actually weld workpiece l. It can be shortened to some extent.

In addition, since the operation of positioning multiple workpieces 1 at predetermined welding processing positions is performed by reciprocating the moving end of each rodless cylinder, the merging operation of the X-Y table is positioned at a predetermined position. Only the operation for welding workpiece 1 is required. Therefore, the first jig stand 15
The welding operation is the same when welding the workpiece 1 set on the second jig stand 16 or when welding the workpiece I set on the second jig stand
-It will be easier to obtain the data necessary to perform the merging operation of Y Chiful. This not only simplifies the work of creating data for merging X-Y tables, but also reduces the teaching time for poems that generate drafts by half, greatly improving work efficiency. It can be made to

Note that while one workpiece is being welded, another workpiece is removed/installed, so that the workpiece 1 is replaced while the second joint plate 14 is moving. However, since the distance between the laser welding points is very narrow, the movement of the second joint plate 14 is extremely small, and the workpiece 1 can be replaced without any problem.

<Effects of the Invention> As previously described, the present invention moves a work jig or a workpiece positioning mechanism in the X direction and the Y direction in a horizontal plane, and moves the work jig or workpiece positioning mechanism in the X direction and the Y direction. In the X-Y table used for assembling or processing the and a pair of parallel slide mechanisms that are reciprocated in the negative direction by the slide mechanism and that reciprocate the ox position δ determination support mechanism in the other direction perpendicular to the one direction. , by setting the arrangement interval of the positioning support mechanisms and the movement stroke of the movement slide mechanism to be the same, and then operating the movement slide mechanism, the workpiece set on one of the positioning support mechanisms can be moved. and the work set on the other positioning support mechanism can be selectively positioned at a predetermined processing position. Therefore, while the workpiece set on one positioning support mechanism is being processed, the workpiece set on the other positioning support mechanism can be attached/removed. As a result, the time required to interrupt processing can be reduced to the time required to replace the positioning support mechanism that is positioned at the predetermined processing position, greatly reducing lost time due to interruptions and shortening work time. [
I can figure it out.

In addition, since the positioning of each workpiece is performed by a slide mechanism and a mechanism to a pair of parallel slides 1,
Even if there are multiple pieces of work set in Chiful,
1-The X-Y chifur can be configured so that it only needs to perform one movement operation↓, and the data necessary to make the above-mentioned X-Y chifur perform a predetermined merging operation can be reduced to one. . I want to, X
- It is possible to simplify the data necessary to operate the Y table, and it is also possible to significantly shorten the time required for teaching during recovery when a 1-Rafle error occurs, improving work efficiency. I can do it.
