Abstract

Two X-Y-oriented receptacles (5) for the workpiece (6) are in a common workplane between an input station (7), a workstation (8) and an output station (9). And can be operated independently of each other in an alternating cyclic process of movement. The propelling device and the guidance device (2, 3, 4) for the two receptacles (5) are arranged to the both sides of the workplane. Therefore, it is possible to process the workpiece (6) almost uninteruptedly.

Description

The equipment of automated machining of workpieces

The present invention relates to a kind of equipment of workpiece, particularly printed circuit board (PCB) being processed automatically by means of at least one conveying device, described conveying device has a movably receiver that is used for workpiece, wherein this receiver is by an intersection guiding device, between a plurality of stations in a processing plane, at least two coordinate direction motions.The processing of indication here also can be regarded as the preparation measures that (for example) measures workpiece.

Workpiece (for example) usually takes out from an input station by means of a manipulator, and is delivered to machining position from there, and is delivered to the output station from this station, and wherein these stations are located substantially on the plane.For workpiece is gone in the course of processing of diverse location, workpiece must be freely positionable on processing stations.It can be reached by following measure, and promptly workpiece remains in the receiver of manipulator during processing and carries out corresponding mobile.Total process-cycle can be by dress workpiece, input, export and unload workpiece institute's time spent and decide.

Task of the present invention is to improve the part efficient of equipment.

Above-mentioned task will solve by the described invention of claim 1.Workpiece or can directly be contained in the receiver thus, or be receivable on the work rest, this work rest is then clamped by conveying device, and this work rest constitutes described receiver duration of processing then.Processing plane is positioned within the altitude range of receiver.If workpiece (for example) surpasses the outside dimension of receiver when a side clamps, then should outstanding profile outside dimension will be can be regarded as.

Layout by two conveying devices has shortened the process-cycle greatly.Because guiding and drive unit are positioned at both sides outside the processing plane, thereby two present receivers can pass through in two coordinate directions in the one-period motion process with not colliding mutually.Thereby always can carry two workpiece simultaneously, and can process in the sequential of a compactness, thus (for example) in the process segment of a workpiece, another receiver can carry out inloading part, piece installing and can operate near processed workpiece.Thereby the workpiece of the processing district of equipment change can corresponding one very the short operation path finish apace.

Further favourable structure of the present invention is documented in the claim 2 to 5.

By means of the structure of claim 2,, will the manufacturing expense of equipment be reduced owing to adopted the identical structure of two halves.

The described frame of claim 3 has realized an optimal layout of guiding and drive unit.

Equipment according to claim 4 can be used for the occasion when using the integrated circuit block support that lumps together with laser processing is a large amount of especially.Wherein the deflecting region of laser beam is fit to the size of integrated circuit block support, and this conveying device makes this receiver move from an integrated circuit block support to another piece integrated circuit block support continuously at two coordinate directions.This single operation, fixed in and process time accumulative total produce a total time of staying, the quantity of this total time of staying by the described integrated circuit block that combines is determined, this quantity now can be determined in the following manner: promptly should be substantially equal in the time of staying of processing stations and be transported to the output station, unload workpiece, move to the input station, load onto processing work and be transported to the needed time of processing stations, and almost can carry out continuous processing to workpiece thus.

Second laser cell of record pressed the symmetrical structure layout of equipment in the claim 5, thereby shortened the process-cycle greatly.

To do a detailed explanation to the present invention according to the embodiment shown in the figure below.

Fig. 1 is an end view that is used for the equipment of automated machining of workpieces;

Fig. 2 is the top view of equipment shown in Figure 1.

As depicted in figs. 1 and 2, the frame 1 of a U type structure respectively is provided with a linear longitudinal rail 2 at its free end, is used for a cross slide way 3 with this guide rail horizontally set, and guide rail 3 constitutes one with longitudinal rail 2 and intersects guiding structural.One retainer 4 can move on cross slide way 3.The other end of this retainer 4 is provided with a receiver 5 that is used for as the workpiece 6 of printed circuit board arrangement, and cross slide way 3 and retainer 4 on its guide rail (for example) can be driven by linear electric machine.

By means of these guide rails and conveying device, receiver 5 moves in can be between an input station 7, processing stations 8 and output station 9, by a processing plane shown in the motion arrow.At processing stations, the lifter motion that receiver 5 can be lacked, thus workpiece 6 can freely be located at different coordinate positions.Relative processing plane two sides with track-type facilities of this driving are arranged to the minute surface symmetry, and wherein retainer 4 has a spacing with this processing plane, and this two receiver all is arranged in the isometry position of processing plane.Wherein retainer 4 is configured to be positioned at beyond the height profile of receiver 5, with and mobile route not interrupted.

In addition, also be provided with two laser cells in two sides of processing plane, they can produce the laser beam that turns to, this laser beam perpendicular to processing plane penetrate on workpiece 6.Can process simultaneously plate-like workpieces 6 in both sides with this.The purposes of this type of processing is the be coupled lead track configuration of integrated circuit component of the meticulousst being used for of (for example) processing.
