But, in the method for measurement of being carried out processing dimension by people, produce because of because of carelessness with misunderstand the measurement mistake, the mistake in computation of corrected value and input error etc. that cause.Therefore, the applicant of the application proposes following technology, in following patent document 1, on facing attachment, measurement becomes the processing dimension of the sheet material of the object of measurement processing and sampling check automatically, revises the workbench of facing attachment and the position of instrument according to this measurement value.
That is, two top video cameras 5,5 are set at the upstream side (side that workpiece is moved to) of the instrument 3 of facing attachment and are configured at the bottom video camera 6,6 (dummy line in Fig. 8) below them.And, for the substrate of the substrate and sampling check that will measure processing, two top video cameras 5,5 are utilized to read on workpiece 1 two telltale marks 4,4 on the width of mark, the setting angle of workbench 2 and the position of instrument 3, then make workbench 2 along direction of feed (+Y-direction) relative movement (hereinafter referred to as " feeding is moved "), chamfer machining is carried out to first-phase opposite side 8,8 simultaneously.After this process finishing, make workbench 2 along Return-ing direction (-Y-direction) relative movement (hereinafter referred to as " returning movement "), utilize a video camera in top video camera 5 to read two telltale marks 4 arranged along direction of feed simultaneously, detect the inclination of workpiece.Then, again make workbench 2 carry out feeding and move, utilize top and bottom video camera 5,6 to measure upper and lower processing dimension.
Then, make workbench 2 90-degree rotation, make workbench 2 carry out returning movement, carry out the chamfer machining of second-phase opposite side 9,9 simultaneously, again carry out feeding and move and the inclination detecting workpiece 1.Then, again make workbench 2 carry out returning movement, carry out the measurement of the processing dimension of second-phase opposite side 9 simultaneously.
In the method that patent document 1 proposes, in order to carry out the chamfer machining on four limits and the measurement of processing dimension of substrate, workbench 2 must be made to come and go 3 times (by 6 times).In addition, about the processing of workpiece when not measuring processing dimension, be make workbench 2 carry out feeding to move and process first-phase opposite side 8,8 simultaneously, make workbench 2 90-degree rotation, make workbench 2 carry out returning and mobilely process second-phase opposite side 9,9 simultaneously.
On the other hand, patent document 2 proposes a kind of facing attachment, and at the workbench width left and right sides of workbench relative to the direction of feed upstream side of instrument, configuration is observed the top video camera of the upper surface of substrate and observed the sidepiece video camera of side.In the apparatus, top video camera is utilized to read in the telltale mark that workpiece marks, and carry out the position setting of lathe of work level angle and instrument, moved by the feeding of workbench and process first-phase opposite side, by returning the mobile measurement carrying out the processing dimension of first-phase opposite side, position after returning makes worktable rotary 90 degree, is moved carry out chamfer machining to second-phase opposite side by feeding again, by again return the mobile processing dimension measuring second-phase opposite side.In the method that this patent document 2 proposes, workbench is made to come and go 2 times (by 4 times), to carry out the chamfer machining on four limits and the measurement of processing dimension.
In addition, following patent document 3 discloses following structure, second video camera of the band secondary light source being equivalent to the bottom video camera of patent document 1 is disposed in parallel in the outside of the first video camera being equivalent to top video camera, utilizes two speculums of left and right to make the irradiation of secondary light source reflex to the lower surface of glass plate.

[patent document 3] Japanese Unexamined Patent Publication 2004-99424 publication
In the invention that patent document 1 describes, the workpiece about measurement processing dimension carries out processing and measuring for 3 times by coming and going, and then comes and goes only process for 1 time about the workpiece do not measured.On the other hand, in the invention that patent document 2 describes, by coming and going processing and the measurement of carrying out workpiece for 2 times.In the invention of patent document 1, using the tilt detection of workpiece as independently measuring project, so processing and measurement need round 3 times, if but as patent document 2, do not carry out the tilt detection of workpiece, then can by round processing and the measurement of carrying out workpiece for 2 times.
The method that patent document 1 and 2 describes is all carry out processing and measuring respectively by the relative movement of independently workbench.Therefore, in order to carry out processing and the measurement on 4 limits, need the relative movement (by 4 times) carrying out least four times.
According to the structure of instrument, the table feed direction sometimes adding man-hour is restricted to a direction.During this situation, the throughput direction along workpiece arranges 2 facing attachments, arranges therebetween and makes changing of workpieces to the turning platform of 90 degree, and this structure compares the productive temp being conducive to accelerating to process.But, during this situation, in the facing attachment of existing structure, the measurement of processing dimension can not be carried out on facing attachment.
On the other hand, in the facing attachment with the mechanism making workpiece 90-degree rotation, as patent document 1,2 describes, by carrying out the spinning movement of workpiece during the round relative movement of workbench, 1 facing attachment can be utilized to carry out the processing on four limits.And, man-hour is added when what only carry out workpiece when the relative movement in a direction, need to make workbench return, to carry out next processing action, so think if the measurement of processing dimension can be carried out when this returns mobile, the increase of productive temp can not be produced because of automatically measuring processing dimension on facing attachment.
But in fact when carrying out fast returning mobile, the image of video camera flashes, the measurement of processing dimension can not be carried out, use can the emery wheel of rapid processing time, return speed during measurement sometimes must be made slower than the feed speed adding man-hour.That is, although can return movement fast when not measuring, when measuring, return speed is slack-off, therefore causes productive temp to extend.
Because this situation, after often carrying out predetermined multiple work pieces process, carry out the measurement of a workpiece size, the corrected value that setting is necessary.During this situation, need to leave and take surplus to set corrected value, with in the multiple work pieces process during before making on carrying out once measurement, mismachining tolerance is no more than permissible value, can not produce defective work.That is, need with the precision higher than allowed mismachining tolerance to set corrected value.If this larger surplus can be obtained, then correspondingly can increase the processing number of the workpiece during measurement action, can productivity be improved.
But, when required machining accuracy becomes strict, obtain this edge more difficult, finally must measure processed after the processing dimension of whole workpiece, and change corrected value as required at any time, have to reduce productivity in the facing attachment of existing structure.
Summary of the invention
The present invention proposes to solve the problem.That is, problem of the present invention is to provide a kind of facing attachment, can carry out the measurement of processing dimension, and increase productive temp completely or hardly, therefore, it is possible to realize higher machining accuracy and can not reduce machining accuracy to the whole workpiece after processing.
In the present invention, the problems referred to above are solved by providing facing attachment, described facing attachment is in the width both sides of the direction of feed upstream side of workbench 2 opposite tool 3, namely workpiece 1 is by the width both sides of side be sent at first on device, the upstream side top video camera 5a of the upper surface of the both sides edge of workpiece is observed in configuration, top, the downstream video camera 5b of the upper surface of the both sides edge of workpiece 1 is observed in the downstream, table feed direction being simultaneously arranged on instrument 3, with bottom, the downstream video camera 6b of the lower surface of the both sides edge at this downstream observation workpiece.
The interval of the direction of feed of instrument 3 and downstream video camera 5b, 6b is fixing, and this interval is less than the interval of the direction of feed of instrument 3 and upstream side top video camera 5a, is generally below its half.Further, the structure of video camera 5a, 5b, 6b and instrument 3 movement in the width direction simultaneously can be realized.Therefore, it is possible to adopt following structure, that is, the width travelling carriage 16 making instrument 3 movement in the width direction according to the size of workpiece 1 installs video camera 5a, 5b, 6b, the instrument 3 moved freely under this width travelling carriage 16 is installed.
The chamfering of substrate is carried out at tow sides, so need 4 video cameras to measure the upper and lower processing dimension of dual-side.In facing attachment of the present invention, the number that arranges of video camera compares many two of minimum necessary number.If want the feeding of workbench move (relative movement of positive direction of feed) and return the both direction of mobile (relative movement of negative direction of feed) carries out the chamfer machining of workpiece time, need the bottom video camera 6a that the side portion lower surface observing workpiece is also set at the upstream side of the direction of feed of workpiece.Therefore, when this situation, 4 video cameras have been set up compared with existing structure.
Upstream side video camera 5a, 6a are arranged according to the position relationship identical with existing apparatus with instrument 3.Preferably downstream video camera 5b, 6b are configured such that the distance of the direction of feed between they and instrument 3 is close as far as possible.But, when processing work 1, provide cutting fluid (pure water) to instrument 3, so need to make the water droplet of this cutting fluid not remain in and utilize the part that downstream video camera 5b, 6b observe.Therefore, usually need to arrange air curtain at instrument 3 with between downstream video camera 5b, 6b, to cut off cutting fluid also remove the water droplet be attached on workpiece.
