Detailed description of the invention
While below with reference to accompanying drawings, the embodiment according to the present invention is illustrated.Hereinafter, key element same or equivalent in all accompanying drawings is marked with identical symbol, and the repetitive description thereof will be omitted.
(the 1st embodiment)
First, the manufacture equipment 100 of the plate glass according to the present invention the 1st embodiment is described with reference to Fig. 1 and Fig. 2.Fig. 1 is the approximate vertical view of the major part illustrating the manufacture equipment 100 according to this embodiment.In figure, plate glass 101 is carried from the right direction left direction of paper under the effect of feeding roller.Figure is marked with the plate glass 101 of A to H symbol is illustrated that As time goes on plate glass 101 presents towards and position.Hereinafter, in the drawings the position being marked with the plate glass 101 of A to H symbol is such as called " position A " etc. and illustrates.Send additionally, the plate glass 101 of this embodiment is the melting furnace (not shown) from the upstream side being arranged in manufacturing line and is shaped, and there is " forming direction ".Though plate glass 101 is formed with rectangular shape (rectangular shape), but there is parallel relation between its long limit and forming direction.As it is shown in figure 1, the manufacture equipment 100 according to this embodiment possesses cleaning unit 10 and inspection unit 20.
Cleaning unit 10 is the unit that the plate glass 101 passed through is cleaned.Plate glass 101 is moved into cleaning unit 10 after being cut to arbitrary size in preceding working procedure (not shown).In cleaning unit 10, remove the chip powder etc. of attachment when being cut off by plate glass 101, then plate glass 101 is sent to the inspection unit 20 being positioned at downstream.Additionally, under this embodiment, plate glass 101 is moved into cleaning unit 10 with forming direction.That is, plate glass 101 makes long limit with to move into direction consistent and moves in cleaning unit 10.
Additionally, have a blow-off outlet 11 on cleaning unit 10, it is to plate glass 101 blow out air passed through.In FIG, plate glass 101 will pass through this blow-off outlet 11 from position A to the position B process moved.Blow-off outlet 11 is not upwardly extending in the side orthogonal with the carrying direction of plate glass 101, but upwardly extending relative to the side that the direction orthogonal with carrying direction tilts.According to said structure, it is possible to prevent when plate glass 101 closes on blow-off outlet 11, the power of air is applied to the situation on plate glass 101 quickly, and can apply the power of air at leisure to plate glass 101.Accordingly it is possible to prevent the phenomenon that when plate glass 101 is by blow-off outlet 11, issuable plate glass 101 is shaken in vertical direction.
Inspection unit 20 be plate glass 101 is downstream carried while carry out the unit that checks.In FIG, plate glass 101, from position B to the position H period moved, relies on inspection unit 20 to check.Under this embodiment, plate glass 101 is moved into inspection unit 20 from above-mentioned cleaning unit 10 with the state not rotated.That is, plate glass 101 is to be carried to inspection unit 20 in the way of forming direction is consistent with the maintenance of carrying direction.Again, as it is shown in figure 1, inspection unit 20 possess parallel edge check device 30, rotary apparatus 40, orthogonal edges check device 50, face check device 60, ray detection device 70, high speed stress determination device 80, from ray detection device 90.These devices are except being all arranged on straight line except ray detection device 90.
Parallel edge checks that device 30 is the device checking on the limit (long limit) extended on forming direction in the plate glass 101 that passes through whether existing defects.Parallel edge checks that device 30 has two CCD(ChargeCoupledDevice；Charge-coupled image sensor) camera 31.On the position that each CCD camera 31 is arranged in above plate glass 101 and limit long with the two of plate glass 101 is corresponding.Being moved into place in the process of C at plate glass 101 by position B, the long limit of plate glass 101 will rely on this CCD camera 31 to shoot.And, parallel edge checks that the view data shooting gained based on CCD camera 31 is judged on long limit whether existing defects (defect, slight crack, grinding speckle and stain) by device 30.Additionally, due to view data can be relied on to measure the position, long limit of plate glass 101, the position calculation on long limit according to this size of minor face can be gone out, namely from a long limit of side to the distance on the long limit of the opposing party.Furthermore, check on the quality to improve, it is also possible to above plate glass 101, lower section, place, three, side CCD camera 31 is set simultaneously.
Rotary apparatus 40 is the device making plate glass 101 horizontally rotate.In this embodiment, make plate glass 101 90-degree rotation, the state so that long limit and carrying direction are orthogonal.By means of this, than rotary apparatus 40 on the position in downstream, plate glass 101 is to carry with the direction being orthogonal with forming direction.Rotary apparatus 40 utilizes tool suctorial arm 41 that plate glass 101 is adsorbed at C place, position, mentioned under this embodiment, and makes it land after rotating on the D of position.But, the concrete structure of rotary apparatus 40 is not limited to that, making it rotate with any method can.
At this, with the position of rotary apparatus 40 for benchmark, the configuration sequence of each device constituting inspection unit 20 is as described below.That is, the upstream side of rotary apparatus 40 is configured with parallel edge and checks device 30.Additionally, the downstream of rotary apparatus 40 is configured with orthogonal edges check that device 50, face check device 60, ray detection device 70 and high speed stress determination device 80.It addition, high speed stress determination device 80 location is not particularly limited.Again, as long as orthogonal edges checks that device 50, face check that device 60, ray detection device 70 are positioned at the downstream of rotary apparatus 40, the position of above three device can also exchange.
Orthogonal edges checks that device 50 is the device checking on the limit orthogonal with forming direction (minor face) of plate glass 101 passed through whether existing defects.Orthogonal edges checks that device 50 has two CCD camera 51.CCD camera 51 is arranged in above plate glass 101 and on the position corresponding with two minor faces of plate glass 101.Moved into place in the process of E by position D at plate glass 101, rely on this CCD camera 51 that the minor face of plate glass 101 is shot.And, the view data based on shooting gained is judged on minor face whether existing defects.Again, owing to view data can be relied on to measure the minor face position of plate glass 101, therefore also calculate the size on long limit based on the position of this minor face, namely from side's minor face to the distance of the opposing party's minor face simultaneously.It addition, check on the quality to improve, it is also possible to above plate glass 101, lower section, position, three, side CCD camera 51 is set simultaneously.
Face checks that device 60 is the device on the whole surface checking the plate glass 101 passed through.Face checks that device 60 has multiple CCD camera 61.CCD camera 61 is positioned at above plate glass 101, and is arranged on the direction orthogonal with carrying direction.Moved into place in the process of F by position E at plate glass 101, rely on these CCD camera 61 that the whole surface of plate glass 101 is shot.And, the view data based on shooting gained is judged, and whether plate glass 101 exists the surface defect attachment of foreign body (scratch) and internal flaw (bubble, foreign body be mixed into).It addition, the scuffing on plate glass 101 surface is easily formed along forming direction.Therefore, by towards the direction observation surface orthogonal with forming direction, when there is scuffing, view data can be susceptible to change, thus being readily inspected out scuffing.It is to say, rely on this structure that the degree of accuracy of surface inspection can be made to improve.
Ray detection device 70 is the device on the surface checking the plate glass 101 passed through on the line orthogonal with forming direction (while the direction relative movement orthogonal with forming direction).Ray detection device 70 has thickness measurement sensor 71 and striped checks sensor 72.Thickness measurement sensor 71 is observed after irradiating above plate glass 101, at the light that plate glass 101 upper surface and lower surface reflect.Ray detection device 70 is based on this observed result, it is possible to determine the thickness at the plate glass 101 checked on position.Additionally, striped inspection sensor 72 observation is penetrate the light within plate glass 101.Ray detection device 70 is based on this observed result, it is possible to detect the striped within plate glass 101.In FIG, plate glass 101 is moved into place in the process of G by position F, has also checked whether that striped exists while measuring plate glass 101 thickness.At this, easily there is the change of thickness in the plate glass 101 with forming direction on the direction orthogonal with forming direction.Again, striped is formed along forming direction.Therefore, as in the present embodiment, check thickness and striped etc. while relatively moving towards the direction orthogonal with forming direction, the thickness of plate glass exception, striped etc. can be detected accurately with this.
High speed stress determination device 80 is the device measuring at a high speed plate glass 101 internal residual stress.High speed stress determination device 80 has multiple stress determination sensor 81.Stress determination sensor 81 is positioned at above plate glass 101, and is arranged on the direction orthogonal with carrying direction.High speed stress determination device 80 has the illuminating part (not shown) being positioned at below plate glass 101.Illuminating part is to plate glass 101 lower surface irradiating laser.Laser penetration is received light by stress determination sensor 81 behind this plate glass 101 inside.And, high speed stress determination device 80 calculates residual stress based on the goniometer of the laser being incident upon stress determination sensor 81.In FIG, plate glass 101 is moved into place in the process of H by position G, determines the residual stress of this plate glass 101.Generally, compare spended time with high-precision measuring residual stress, but in the high speed stress determination device 80 of this embodiment, be configured with multiple stress determination sensor 81 and illuminating part, reduce simultaneously and measure number of times, achieve the high speed of mensuration with this.
It it is the device that the plate glass 101 taken out from manufacturing line is checked from ray detection device 90.The mode automatic or manual taking out plate glass 101 can.It addition, in this embodiment, being formed as by the plate glass 101 checked from ray detection device 90 can from the position G structure taken out.In this embodiment from ray detection device 90, carrying out the mensuration of mensuration and the plate thickness resulting from the residual stress of plate glass 101 simultaneously.At this, Fig. 2 is the approximate three-dimensional map from ray detection device 90.In ray detection device 90, plate glass 101 it is placed on it and checks, hereinafter, the direction (drawing on be direction from upper right to lower-left) parallel with the long limit of this plate glass being set to " X-direction "；The direction (drawing on be from direction left to bottom right) parallel with plate glass 101 minor face is set to " Y-direction ".
As in figure 2 it is shown, there is table top 91, drive division 92, plate thickness sensor 93 and stress determination sensor 94 from ray detection device 90.Table top 91 is by the table top of plate glass 101 horizontal positioned, and is formed as the structure can slided towards X-direction.Additionally, table top 91 has been regularly formed multiple through hole (not shown), their through direction and the perpendicular of table top 91.Configured under at table top 91 has illuminating part (not shown), and when launching laser from this illuminating part, this laser is through through hole and irradiates to plate glass 101.Drive division 92 is positioned at the top of table top 91, drives along the track 95 extending Y-direction towards Y-direction.Drive division 92 is provided with plate thickness sensor 93 and stress determination sensor 94.That is, plate thickness sensor 93 and stress determination sensor 94 are adjacent to, and are formed as the structure that simultaneously can move together with drive division 92 towards Y-direction.It addition, along with stress determination sensor 94 moves towards Y-direction, above-mentioned illuminating part also moves towards Y-direction.
Plate thickness sensor 93 can check the flexibility of plate glass 101, and receives the light reflected by plate glass 101.Further, plate thickness sensor 93 detects the flexibility of plate glass 101 based on the angle of the light received.Furthermore, it is possible to calculate the plate thickness of plate glass 101 from these detection data.Stress determination sensor 94 is essentially identical with the stress determination sensor 81 in above-mentioned high speed stress determination device 80.But, the accuracy of detection of the stress determination sensor 81 that the accuracy of detection from the stress determination sensor 94 in ray detection device 90 is higher than in high speed stress determination device 80.Additionally, in this embodiment, be based not only on the angle of the laser carrying out self-luminescent part received by stress determination sensor 94, plate thickness calculating (mensuration) being additionally based upon the actual plate glass 101 that plate thickness sensor 93 calculates goes out residual stress.
Such as, even if the angle of the laser of stress determination sensor 94 reception is identical, if but the plate thickness of plate glass 101 is different, then and residual stress would not be identical.That is, in order to determine correct residual stress, it is necessary to the information of the plate thickness of plate glass 101.But, in the past, the device measuring the residual stress of plate glass 101 is that the device measured from the plate thickness that can carry out plate glass 101 is independent set.Therefore, residual stress is calculated when hypothesis plate glass 101 plate thickness is certain, and its result can produce the error of about 10% degree.Relative to this, this embodiment from ray detection device 90 owing to possessing both plate thickness sensor 93 and stress determination sensor 94, therefore residual stress can be calculated based on the plate thickness of actual plate glass 101, its result is able to carry out the mensuration of residual stress with high accuracy, and makes quality management also become easy.
Possess as described below plate glass 101 being checked from ray detection device 90 of above structure.First, adjust table top 91 position in the X direction, make plate thickness sensor 93 and stress determination sensor 94 can measure near the minor face of a side of plate glass 101.Then, when fixing table top 91 position, drive division 92 is little by little changed the long limit to opposite side, the position from the long edge Y-direction of plate glass 101 side, and the plate thickness carrying out plate glass 101 measures and stress determination.And, when drive division 92 arrives the long limit of the opposite side of plate glass 101, it is make table top 91 slightly move with X-direction specifically, in the same way, drive division 92 is little by little changed the long limit to side, the position from the long limit of plate glass 101 opposite side, carries out plate thickness mensuration and stress determination simultaneously.Repeating above operation, after whole plate glass 101 has carried out inspection, off-line inspection terminates.It addition, plate thickness measures and stress determination is to launch with high accuracy, any one all compares spended time, but in this embodiment from ray detection device 90, checking owing to can carry out these simultaneously, therefore shorten on the basis of minute, not only precision is high and efficiency is high.
It is above the plate glass according to this embodiment is manufactured the explanation of equipment 100.Inspection unit 20 in this embodiment has possessed face and has checked device 60 and ray detection device 70.When this stream oriented device checks from the direction orthogonal with forming direction, defect can be detected accurately.And, these devices are owing to centralized configuration is in the downstream of rotary apparatus 40, and therefore the direction without repeating plate glass 101 is changed, it is possible to check expeditiously.It addition, in this embodiment, although inspection unit 20 has possessed high speed stress determination device 80, but owing to passing through also can measure the residual stress of plate glass 101 from ray detection device 90, therefore, inspection unit 20 can not also possess from ray detection device 90.
(the 2nd embodiment)
It follows that the manufacture equipment 200 of the plate glass 101 according to the present invention the 2nd embodiment is described with reference to Fig. 3.Fig. 3 is the approximate vertical view of the major part illustrating the manufacture equipment 200 according to this embodiment.When this embodiment and the 1st embodiment are contrasted, according to the manufacture equipment 200 of this embodiment plate glass 101 move into direction and constitute inspection unit 20 device configuration sequence in different from the manufacture equipment 100 according to the 1st embodiment.Aspect in addition, the two equipment substantially has identical structure.
Particularly in this embodiment, plate glass 101 is moved to cleaning unit 10 and inspection unit 20 with the direction orthogonal with forming direction.Again, when the configuration sequence of the device of composition inspection unit 20 is with rotary apparatus 40 for benchmark as described below.That is, it is configured with orthogonal edges at the upstream side of rotary apparatus 40 and checks that device 50, face check device 60 and ray detection device 70.Again, it is configured with parallel edge in the downstream of rotary apparatus 40 and checks device 30 and high speed stress determination device 80.So, when this embodiment, owing to face to be checked the centralized configuration such as device 60 and ray detection device 70 is in the upstream of rotary apparatus 40, therefore the same with the situation of the 1st embodiment, direction without repeating plate glass 101 is changed, and can carry out high-precision inspection expeditiously.
(the 3rd embodiment)
It follows that the manufacture equipment 300 of the plate glass 101 of the 3rd embodiment according to the present invention is described with reference to Fig. 4.Fig. 4 is the approximate vertical view of the major part illustrating the manufacture equipment 300 according to this embodiment.During by this embodiment with the 1st embodiment contrast, manufacture equipment 300 according to this embodiment does not possess parallel edge at inspection unit 20 and checks that device 30 and orthogonal edges check device 50, and replace and possess full marginal check device 35 on this point, different from manufacture equipment 100 structure according to the 1st embodiment.Aspect in addition, the two equipment substantially has identical structure.Therefore, will illustrate centered by full marginal check device 35 at this.
The full marginal check device 35 of this embodiment is the device checking 101 4 limits of plate glass.Full marginal check device 35 has 4 CCD camera 36.Each CCD camera 36 is positioned at the top of plate glass 101, and is arranged respectively on the position corresponding with plate glass 101 4 limit.The plate glass 101 moved into full marginal check device 35 temporarily ceases it and transmits, and each CCD camera 36 can move along each self-corresponding limit in this state.And, this limit, in the period moved along corresponding limit, is shot by each CCD camera 36.And, full marginal check device 35 is based on the view data relying on each CCD camera 36 to shoot gained, it is judged that whether existing defects on each limit.It addition, more than, although describing full marginal check device 35 there is the situation of 4 CCD camera 36, but it is not limited to such structure.For example, it is also possible to be formed as arranging 1 CCD camera 36, and make its structure moved along the whole four edges of plate glass 101.It addition, for the quality improving inspection, it is also possible to above each limit of plate glass 101, lower section, position, three, side CCD camera 36 is set simultaneously.
