Detailed description of the invention
To describing for implementing mode of the present invention, but the invention is not restricted to following embodiment below with reference to accompanying drawing, can apply various distortion and displacement to following embodiment without departing from the scope of the invention.
In present embodiment, the cross grinding of glass substrate is described with the method for trimming of grinding stone.
First, use Figure 1A, Figure 1B, Fig. 2 to describe the configuration example of face grinding device of the glass substrate that is provided with cross grinding grinding stone.
Figure 1A, Figure 1B are the schematic diagrames of the face grinding device 10 of glass substrate, and Figure 1A represents side view, and Figure 1B represents top view.It should be noted that, the method for trimming of present embodiment is not limited to described face grinding device.
The state that exposes from holding unit 11 with end face as the rectangular piece W (glass substrate) of grinding object, remain on holding unit 11 in the mode that can load and unload.Holding unit 11 is configured in can be upper along the mobile moving body S of left and right directions in Fig. 1 (direction of arrow in Figure 1A, Figure 1B), forms in the mode that can utilize conveyer 12 to transport workpiece W via moving body S along left and right directions.In addition, conveyer 12 can form in the mode that can utilize the travelling speed (feed speed) of controller 100 described later (control part) to workpiece W to control.
The workpiece W remaining on holding unit 11 is transported to the position that is provided with grinding mechanism 13 by conveyer 12, its both ends of the surface part is carried out to grinding and chamfered (being only denoted as below grinding processing).In Figure 1B, illustrate that left and right at conveyer 12 (with the orthogonal direction of the carriage direction of workpiece W) has respectively configured the example (only having recorded 1 for ease of understanding structure in Figure 1A) of 1 grinding mechanism 13, but for example also can change the kind, roughness of grinding stone and configure multiple grinding mechanisms along carriage direction and cut purposes, fine finishining purposes for corase grind.
In order to regulate stock removal (polishing width), grinding mechanism 13 preferably forms in the mode that can change manually or automatically the distance between workpiece W.Particularly, such as grinding mechanism 13 preferably possesses servo control mechanism etc.In present embodiment, the position of grinding mechanism 13 (with the distance of workpiece W) also can form in the mode that can be controlled by controller 100 described later (control part).
As shown in Figure 1B, the motor 131 that grinding mechanism 13 disposes columniform grinding stone (being only recited as below " grinding stone ") 132 for cross grinding therein, as rotating shaft, grinding stone 132 rotarilyd actuate taking the central shaft of grinding stone 132 in the time that grinding is processed.In addition, supply with the cooling agent feed mechanism 14 of cooling agent, can be connected with grinding mechanism 13 via the attraction mechanism 15 of the cooling agent after pipeline L suction use for part periphery contact with workpiece W to grinding stone 132 when grinding.
It should be noted that, after the cooling agent that is conventionally supplied to the part periphery that grinding stone contacts with workpiece W by above-mentioned cooling agent feed mechanism 14 when the grinding is reclaimed by above-mentioned attraction mechanism 15, recycle after removing foreign matter by filter etc.Therefore, resemble existing method for trimming in the case of using material and conduct to be ground the trim materials that the workpiece W (glass substrate) of thing is different, there is following problem: in cooling agent, sneak into trim materials, thereby produce scar because the foreign matter of not removed completely by filter in grinding process makes workpiece W.But, according to the method for trimming of present embodiment, use glass substrate as trim materials, therefore, even after repairing, foreign matter (materials different from being ground thing) can not be blended in cooling agent yet, therefore can eliminate the problems referred to above yet.
The kind of grinding stone 132 is not particularly limited, for example, can use ciamond grinder.And, from the horizontal side view of the grinding stone shown in Fig. 2 also, the side (side face) of grinding stone 132 is formed with groove 132 (a), and transporting workpiece W by the end face of workpiece W is contacted with this groove when carries out the grinding processing of the end face of workpiece W.Now, carry out the chamfering of the end face of workpiece W according to the surface configuration of groove.The example that 1 groove 132 (a) is set is shown in Fig. 2, but for example also can axially with predetermined distance, many grooves be set, in the time of continuous operation face grinding device, changed used groove according to the stock removal of each groove etc.
It should be noted that, at this, to transporting workpiece W and the face grinding device that its end face carries out grinding being illustrated, but also can fix and mode that grinding mechanism 13 moves forms with workpiece W, also can be so that by workpiece W, grinding mechanism 13, the two transports, mobile modes form.
And present embodiment relates to the method for trimming of the cross grinding grinding stone that is disposed at grinding mechanism in the face grinding device of the glass substrate of above-mentioned explanation, below the method for trimming of present embodiment is described.
If carry out grinding with common grinding treatment conditions (creating conditions of product), the phenomenon such as come off that can produce that obstruction, the abrasive particle the surperficial hole of the groove of grinding stone blocked by chip (grindstone dust) drop, thus the working ability of grinding stone is declined.
The method for trimming of present embodiment uses glass substrate as trim materials, the mode that the feed speed stock removal slack-off, glass substrate of glass substrate increases compared with the condition when end face being carried out grinding and processed when manufacturing with common product to grinding stone cross grinding for (face grinding device) thus supply with glass substrate and make the working ability recovery of grinding stone.
Can think this be because: by making compared with the condition that adds man-hour with the common product of glass substrate, feed speed is slack-off, stock removal increases, can obtain following effect: the surperficial chip (grindstone dust) of the groove that is attached to grinding stone is removed, thereby or a part for the abrasive particle bond material of easily being pruned in grinding stone is removed and made abrasive particle be exposed to the surface of the groove of grinding stone.
At this, the feed speed of glass substrate refers to the relative velocity between glass substrate and grinding mechanism portion, for example as shown in Figure 1A, Figure 1B by grinding mechanism 13 fixing and transport the face grinding device of glass substrate in refer to the travelling speed of glass substrate (workpiece).In addition, refer to the translational speed of grinding mechanism 13 in the situation that of grinding mechanism 13 being moved glass substrate is fixed, making glass substrate, grinding mechanism 13, the two transports, refers to mobile in the situation that both relative velocity.
The size (width) of stock removal when in addition, stock removal (processing capacity) refers to the grinding processing of carrying out glass substrate end face.
When common product is manufactured, the condition of grinding processing such as, is specified by the characteristic of face grinding device, the shape of glass substrate, the desired surface roughness of product, the kind (surface roughness, kind) of grinding stone etc. of glass substrate.Therefore, when common product is manufactured, the condition of the grinding processing of glass substrate end face does not limit, for example, be preferably that 6000～24000mm/ minute, stock removal are to carry out under the condition of 80～240 μ m in the feed speed of glass substrate.
And, the method for trimming of present embodiment is supplied with as the method for the glass substrate of trim materials to cross grinding grinding stone as long as the mode that feed speed is slow and stock removal is many of the glass substrate of the grinding processing when manufacturing than product, and other conditions do not limit.
The more than 1/6 of feed speed of the glass substrate while end face being carried out to grinding processing when the feed speed of the glass substrate using as trim materials can be set as product manufacture.The more than 1/6 of feed speed of the glass substrate while manufacture for product by the feed speed of glass substrate that makes to use as trim materials, can suppress the decline of the operating efficiency of the face grinding device of glass substrate, can make productivity ratio remain good.Below 1/3 of feed speed of the glass substrate while end face being carried out to grinding processing when the feed speed of the glass substrate using as trim materials in addition, can be set as product manufacture.Below 1/3 of feed speed of the glass substrate while manufacture for product by the feed speed of glass substrate that makes to use as trim materials, can obtain sufficient finishing effect.
The more than 1.1 times of stock removal of the glass substrate while end face being carried out to grinding processing when the stock removal of the glass substrate using as trim materials can be set as product manufacture.The more than 1.1 times of stock removal of the glass substrate while manufacture for product by the stock removal of glass substrate that makes to use as trim materials, can obtain sufficient finishing effect.Below 3.5 times of stock removal of the glass substrate while end face being carried out to grinding processing when the stock removal of the glass substrate using as trim materials in addition, can be set as product manufacture.Below 3.5 times of stock removal of the glass substrate while manufacture for product by the stock removal of glass substrate that makes to use as trim materials, can prevent breaking glass panel in grinding processing.
The glass substrate using as trim materials is not particularly limited, and can use various glass substrates.For example can prepare glass substrate and be exclusively used in finishing, it is used in the time repairing.In addition, the glass substrate using also can use common product to manufacture time.
Be used for the special glass substrate of repairing in the case of preparing, its size is not particularly limited, as long as for guaranteeing the size of sufficient stock removal.But, be preferably with the size of the glass substrate same degree of common product so that without formation, the configuration of changing face grinding device.The glass substrate that particularly preferably used thickness is identical with the glass substrate of product is to can tackle the surface configuration of the groove of grinding stone.Material is also not particularly limited, but preferably uses the glass substrate that material is identical with product glass substrate.
In addition, the glass substrate using as trim materials can use the glass substrate of the grinding processing of having carried out in advance end face or not carry out in advance any one in the glass substrate of grinding processing of end face.
As described later shown in embodiment 1,2, no matter whether the glass substrate using as trim materials carries out the grinding processing (chamfer machining) of end face part, can be in the case of not making the surface configuration of groove of grinding stone obtain sufficient finishing effect deforming.
Particularly not carrying out in advance, the glass substrate of grinding processing of end face part, can omitting the operation that is processed as in advance glass substrate in the case of using, therefore can improve operating efficiency, is also preferred from the viewpoint of cost.
In addition, now, can be in the situation that not changing glass substrate only by the operating condition that for example carries out the face grinding device of the glass substrate after common running is changed (make feed speed slack-off, stock removal is increased) repair.In addition, finishing can return to the go forward side by side grinding processing of oozy glass substrate end-face of common operating condition after finishing.Therefore, can suppress especially the decline of the face grinding device operating efficiency of glass substrate, be therefore preferred.
And the glass substrate after preferably using as trim materials also uses (can use) as product.For example, the glass substrate using in the time using product to manufacture, as trim materials, as long as the stock removal increasing in the time of finishing falls in the margin of tolerance of product, can directly use as product.Now, do not need the glass substrate that uses in finishing discard or reprocess, therefore, the aspect of the load from reducing costs, to environment, is also preferred.
While finishing, without only repairing with 1 glass substrate.For example, in the time only cannot obtaining sufficient finishing effect by 1 glass substrate, cannot guarantee sufficient stock removal in the degree of the desired machining accuracy of product (tolerance) time, also can use 2 or 2 above multiple glass substrates to repair.
The moment of carrying out the method for trimming of present embodiment is not particularly limited, and can set arbitrarily.For example can repair termly, the product after grinding is checked and repaired at any time based on check result by the accumulation stock removal based on grinding stone for cross grinding (groove of grinding stone).
Fig. 3 illustrates the control flow example of concrete finishing.In this example, based on the accumulation stock removal of grinding stone enforcement finishing at any time for cross grinding.
First, in the face grinding device 10 of glass substrate end face, cross grinding grinding stone is set, the condition entry into service while manufacture with product.At this, will cross grinding be got back to zero-bit (step S10) with the grinding stone accumulation stock removal (A) that the accumulation stock removal (processing capacity) of grinding stone is counted.In addition, by the accumulation stock removal (processing capacity) after finally repairing, currying work is got back to zero-bit (step S12) every grinding stone accumulation stock removal (B).
Then carry out the cross grinding manufacturing procedure (step S14) of glass substrate.This operation is the operation of in the time that product is manufactured, the end face of glass substrate being carried out to grinding processing.Glass substrate with first stock removal to the end face of this glass substrate is carried out to grinding to cross grinding in grinding stone feeding with the first feed speed.Accompany therewith, according to stock removal, grinding stone accumulation stock removal (A), currying work are summed up to (step S16) every the value of grinding stone accumulation stock removal (B).
Then,, in the process of grinding processing of carrying out glass substrate end face, for example, carry out following judgement in the moment of regulation (while often carrying out the grinding processing of a glass substrate end face).
First, judge whether grinding stone accumulation stock removal (A) reaches setting value (A1) (step S18).At this, setting value (A1) for having specified from cross grinding grinding stone is set to face grinding device until the value of the accumulation stock removal of grinding stone for the cross grinding that need to change, for example for the formation based on face grinding device, grinding stone cross grinding for, to be ground thing be that the kind etc. of glass substrate has been carried out the value specifying in advance., setting value (A1) is defined as the limiting value that can use of cross grinding grinding stone, therefore, just need to change cross grinding grinding stone in the time being judged to be to reach setting value (A1).Therefore, in the time being judged to be to reach setting value (A1), (step S18 is) shuts down (step S34), changes cross grinding grinding stone.In the time being judged to be not reach setting value (A1), (step S18's is no) moves to next judgement.
Then, be to be judged as while not carrying out sufficient grinding etc. in the result that the end face of glass substrate of manufacturing is checked, determine whether and press any glass finishing start button (step S20) of pressing arbitrarily.
In the time that glass finishing start button is pressed arbitrarily (step S20 is), implement finishing process described later (step S24).Move to next judgement being judged as (step S20's is no) while not pressing.
Then, judge whether currying work reaches setting value (B1) (step S22) every grinding stone accumulation stock removal (B).At this, setting value (B1) is until the value of the accumulation stock removal of the cross grinding of repairing grinding stone next time after having specified to repair.Setting value (B1) is also same with the situation of above-mentioned setting value (A1), for example for the formation based on face grinding device, grinding stone cross grinding for, to be ground thing be that the kind etc. of glass substrate has been carried out the value specifying in advance.
Being judged as (step S22's is no) while not reaching setting value (B1), repeat the grinding processing of glass substrate end face.
Then, being judged as (step S22 is) while reaching setting value (B1), as mentioned above, setting value (B1) is for having specified finally to repair rear until therefore the value of the accumulation stock removal of the grinding stone of repairing automatically carries out finishing (step S24) next time.
In finishing, as mentioned above the feed speed of glass substrate (process velocity of grinding stone) is changed to the feed speed of finishing use, and change the position of grinding mechanism so that stock removal reaches the condition (step S26) while finishing.Then, use glass substrate to repair (step S28) as trim materials.This operation is the operation that uses the end face of this glass substrate as the trim materials of cross grinding grinding stone, cross grinding to be repaired with grinding stone.At this, by glass substrate with slow the second feed speed of the first feed speed than above-mentioned to cross grinding grinding stone feeding.In addition, with second stock removal more than the first stock removal, the end face of glass substrate is carried out to grinding.Particularly, control grinding mechanism 13, cross grinding grinding stone and the distance of the end face of the glass substrate using as trim materials are approached.
Finishing cross grinding is carried out after the stipulated time to the setting value (condition when product is manufactured) (step S30, step S32) when feed speed, stock removal are returned to common operating condition, i.e. original grinding processing by the operation of grinding stone.Then, currying work is got back to zero-bit (step S12) every grinding stone accumulation stock removal (B), and again implement the grinding processing of above-mentioned glass substrate end face.
Repeat the grinding processing of glass substrate end face according to above flow chart, can in the case of not stopping the face grinding device of glass substrate end face, repair in the regulation moment thus, carry out the grinding processing of glass substrate end face simultaneously.
In addition, can in the time the glass substrate of defined amount (more than 1) being processed, all carry out the judgement of above-mentioned step S14～step S22 at every turn.
Then, the formation of controller 100 is described.Fig. 5 is the block diagram that functionally represents the formation of controller 100.Controller 100 comprises control part 102 and the storage part 104 that imposes a condition.
Feed speed and the stock removal (position of grinding mechanism 13) of the glass substrate when storage part 104 that imposes a condition is stored above-mentioned setting value (A1), setting value (B1), the conventionally feed speed of the glass substrate in operating condition (when product is manufactured) and stock removal (position of grinding mechanism 13), glass finishing, carry out the judgement of step S18～step S22 of Fig. 3 the regulation moment, carry out the predefined condition such as time of implementation of the regulation of glass finishing.These conditions can be set multiple according to the characteristic of the kind of glass substrate, desired product.
In addition, as illustrated with reference to Figure 1B, changing the kind, roughness of grinding stone and configuring multiple grinding mechanisms 13 when for example corase grind is cut purposes, fine finishining purposes along carriage direction, can impose a condition respectively to each grinding mechanism 13.Storage part 104 these conditions of storage impose a condition.
Feed speed and the stock removal of the glass substrate when time of implementation of in addition, carrying out the regulation of glass finishing for example can repair according to glass are set.For example, as mentioned above, the stock removal in the time making to repair is identical during with common running, can be so that carry out the mode of the time of implementation prolongation of the regulation of glass finishing and set.In addition, also can change to the time of implementation of the regulation of carrying out glass finishing, to will carry out the distance of glass finishing, the piece number that will carry out the glass substrate of glass finishing is set.
The condition of setting in control part 102 reference settings condition storage parts 104 is carried out the control of each step of the flow chart shown in Fig. 3.In addition, the condition of control part 102 based on setting in the storage part 104 that imposes a condition controlled conveyer 12, grinding mechanism 13 and common operating condition and glass finishing carried out.
It should be noted that, in the time that above-mentioned any glass finishing start button is pressed, for example, represent being set as of mark " opening (on) " of this meaning, control part 102 can carry out with reference to this mark the judgement of the step S20 of Fig. 3.
Controller 100 for example can be made up of the computer with the CPU (CPU), input-output equipment, storage device etc. of carrying out various controls, can be for the formation that makes computer carry out the performing a programme of above-mentioned each function is installed.
When the method for trimming of the cross grinding grinding stone of the glass substrate so far illustrating is used for to the manufacturing process of glass substrate,, when using the manufacture method of glass substrate of this method for trimming, can in the case of not stopping the manufacturing installation of glass substrate, carry out the finishing of grinding stone.Therefore, the productivity ratio that can make compared with the past improves, and does not need operating personnel to carry out with manual mode of operation, thereby can easily implement finishing.
And, do not resemble existing method and can cause the surface state of the groove of the grinding stone after finishing to produce fluctuation by operating personnel, can stably recover the working ability of grinding stone, also can prevent that the surface configuration that is formed on the groove on grinding stone from producing distortion.Therefore, the more stable glass substrate of quality bills of materials continuously.
