Abstract
A workpiece fixing sheet comprises: a PET sheet as a base body; and a workpiece fixing agent coated on the PET sheet, for fixing a workpiece when the workpiece fixing agent is fused and coagulated according to a temperature, and a difference between a fusion start temperature and a fusion end temperature of the workpiece fixing agent is not more than 5 DEG C.
Description
Technical field
The present invention relates to a kind of work-piece fixation clamp, it can fix workpiece to be processed effectively, after processing, workpiece is broken away from an easy rate; The invention still further relates to the processing method of utilizing this work-piece fixation clamp in addition.
Background technology
When an object (following usefulness " workpiece " refers to) need add man-hour, let it be, and material is pottery, clay, glass or metal; Shape that let it be is that tabular, laminar or three-dimensional special-shaped, traditional way is this workpiece to be bondd and is fixed on the adhesive tape process.
Normally a kind of special hot soarfing of this adhesive tape is from adhesive tape, and when the temperature of workpiece raise, they can successfully separate with workpiece.These hot soarfings are PET (polyethylene) material from adhesive tape, include a kind of blowing agent that is blended in the Pressuresensitive Adhesive, and being heated can foaming.For example when temperature reaches 90 ℃, 120 ℃ or 150 ℃, will see the blowing agent foaming.Therefore, after workpiece processed, as long as hot soarfing is risen to as above temperature from adhesive tape, blowing agent just can expand, and workpiece just can take off from adhesive tape.
Except above-mentioned hot soarfing from adhesive tape, also have and a kind ofly can pass through ultraviolet irradiation, make it the PET plate that separates with workpiece.Because in the surface cement of this plate, contain a kind of component that under the ultraviolet ray irradiation, can weaken bonding force.So after workpiece processed, by this PET plate of ultraviolet irradiation, its bonding force will weaken, workpiece also just can be taken away smoothly.
Yet, when workpiece when adhesive tape takes off, the adhesive on the adhesive tape is because the effect of viscous force can partly be retained in surface of the work, in other words, even workpiece has been taken off from adhesive tape, the adhesive on its surface still might can't be disposed fully.In this case,, just must use alcohol in view of adhesive is an organic material, acetone, organic solvents such as benzene or toluene come the cleaning workpiece surface.But if workpiece is to use the material that is subject to the organic solvent corrosion such as pottery to constitute, workpiece will be damaged in the time of cleaning.Also have with organic solvent cleaning adhesive the time, very complicated to the operation and the processing of organic solvent, cost also can correspondingly increase.
For example, if 1 millimeter of the thickness deficiency of workpiece, when it and adhesive tape took place to break away from, workpiece will deform because of the bonding force effect of adhesive or directly be damaged.
In addition, though the adhesive that uses can adhere to workpiece well, the bonding force between it and the PET plate a little less than, in process, probably just directly separated with the PET plate, this just is difficult to guarantee the normal operation of work flow.
Summary of the invention
After taking all factors into consideration above factor, one of primary and foremost purpose of the present invention just provides a kind of workpiece that can make after being fixed and processing, and can easily break away from the work-piece fixation clamp of workpiece; Second be that the processing method of using this stationary fixture is provided simultaneously.Second purpose of the present invention in addition is the bonding force that will strengthen between the member of PET plate and fixation workpiece.
For finishing above-mentioned target, first characteristics of the present invention are that the fusing initial temperature that is coated in the workpiece fixative on the matrix 11 is not more than 5 ℃ with the difference that melts end temp.As mentioned above, this work-piece fixation clamp is constituted as, and a kind of workpiece fixative that can melt fully and solidify in 5 ℃ or the littler temperature difference is spread upon on the matrix.Characteristics thus, when temperature change, workpiece can be fixed on the stationary fixture at an easy rate, and it is also very simple that workpiece is broken away from work-piece fixation clamp.From the above, when workpiece is fixed, do not use adhesive.Can easily break away from workpiece.About this point, also it should be noted that when this workpiece fixative be melted and solidify and produce on the surface of workpiece very strong when bonding, thereby workpiece is fixed on the stationary fixture forcibly.Therefore, it can prevent effectively that workpiece from moving from matrix in processed process.Therefore, workpiece can accurately be processed.
In this case, the fusing initial temperature of workpiece fixative and the end temp scope that can be set up is within 18 ℃ to 100 ℃.
When temperature range during, just can fix this workpiece according to the material of workpiece to be processed according to above-mentioned the setting.
The main component of described workpiece fixative can be alkane or polyethylene glycol.
As mentioned above, using main component is the workpiece fixative of alkane or polyethylene glycol.When the purity of alkane or polyethylene glycol increased, the temperature difference between fusing initial temperature and the end temp can be further reduced.Therefore, as mentioned above, can make the temperature difference temperature difference between fusing initial temperature and the end temp be no more than 5 ℃.
In addition, for described alkane, shown in following table (1) and (5), normal paraffin hydrocarbons and isoparaffin can be used in combination simultaneously.(annotate: the percentage in the following table all is percentage by weight.) as previously mentioned, when the temperature difference of fusing initial temperature and end temp preferably is no more than 5 ℃.But, being more preferably, the temperature difference of fusing initial temperature and end temp is more less than 5 ℃.Following table has just shown the fusing initial temperature of alkane and the less situation of the temperature difference of end temp.

The specific embodiment
Hereinafter will be in conjunction with the accompanying drawings, do specific descriptions with regard to embodiments of the invention.About this point, among the embodiment that is described below, identical Reference numeral is represented identical part.
Introduce first embodiment at first.On the Workpiece fixing plate of this embodiment,, will fix by pottery, clay, glass, metal (aluminium, iron, red copper, brass or the like) or the workpiece to be processed of resin material by a kind of be heated to predetermined temperature time fusing or the fixative that solidifies.
Fig. 1 is the plane of the Workpiece fixing plate of first embodiment among the present invention, and this Workpiece fixing plate is a work-piece fixation clamp.As shown in the figure, Workpiece fixing plate 10 comprises: as the PET plate 11 of matrix and be coated in workpiece fixative 12 on this PET plate 11.In this connection, in this embodiment, the one side of PET plate 11 scribbles fixative 12, yet workpiece fixative 12 can be coated in the two sides of PET plate 11.
For a concrete workpiece, PZT blank for example to be cut (piezoelectricity zirconium titanate) (piezoelectric zirconate titanate), the component of workpiece fixative 12 can be that the alkane of 40%～100% (percentage by weight) adds 0%～60% alumina (particle diameter: from nanoscale to several millimeters).
Under the situation of cutting conductive plate, the component of the fixative 12 that can rationally use be 40%～99% alkane add 1%～60% carbon (conductive carbon material, particle diameter: from nanoscale to several millimeters).
In this embodiment, workpiece fixative 12 consists of composition (2).In other words, the range of temperature of its fusing and process of setting is 2 ℃～5 ℃.Therefore,, when the heating-up temperature of heated parts fixative 12 only changed 1.2 ℃, fixative 12 just can easily melt and solidify.In this connection, preferably in very little range of temperature, can melt and solidify workpiece fixative 12.
Therefore, workpiece fixative 12 at room temperature (for example 27 ℃) solidify and attached to PET plate 11.If heating plate 10 is to the melting temperature that is not less than fixative 12, as long as be heated to above 1.2 ℃ of fusing point, fixative 12 just can melt.And when temperature was lower than fusing point, fixative 12 can solidify again.
The more detailed explanation will provide in the Work piece processing method introduction hereinafter.In current embodiment, begin processed after workpiece is fixed on the Workpiece fixing plate 10.Afterwards, can inject be approximately 100 ℃ hot water to fixed head 10, fixative 12 will melt, workpiece just can take off from fixed head 10.And when room temperature (27 ℃), fixative 12 is set on the PET plate 11, and it can be by delivery and preservation like a cork like this.So in the present embodiment, the fusing point of fixative 12 is required to be arranged on more than the room temperature, and below the temperature of hot water, in other words, the fusing point of workpiece fixative 12 can be made as 53 ℃.
When the additive of the alkane that comprises complete molten state is placed in the hot water, can avoid workpiece fixative 12 to solidify, the phenomenon that swims in the hot water surface and form thin film takes place.If so, additive rise alkane are dissolved in the hot water, even and after the temperature decline, it still can keep the dissolved state of alkane.
The temperature difference of the fusing initial temperature of the fixative of above mentioning 12 and fusing end temp is by the decision of the degree of scatter of its contained paraffin molecules amount.In other words, this temperature difference can be by the purity decision of alkane in the fixative 12.The molecular formula of alkane can be write as C uniformly
nH
m(n, m can be arbitrary integers).When the numerical value of n hour, just the C number in the molecular formula is seldom the time, the fusing point of alkane is lower.When the C number was a lot, fusing point was with regard to corresponding rising.And when this two classes material a lot of the C number and seldom mixed, fusion temperature will distribute in a segment limit.For for the purity of the paraffin materials of cold melt, for example,, use roughly from 50 to 3000 alkane of its range of molecular weight distributions making it being under the situation of fusing in 2 ℃ such as the temperature that approaches room temperature and the temperature difference.For the purity of paraffin materials that fusing point requires to approach 50 ℃, use roughly from 100 to 10000 paraffin materials of its range of molecular weight distributions.Require to approach 90 ℃ paraffin materials for fusing point, range of molecular weight distributions roughly from 500 to 100000.
In order to reduce the distribution of molecular weight, paraffin materials can be purified.When this purification was controlled by high precision ground, range of molecular weight distributions really can reduce.But the material of being purified can be lossy on amount.The result then is that output reduces, and production cost increases.
After range of molecular weight distributions was dwindled, the purity of material had increased.Meanwhile, the temperature range of fusing has also dwindled.Therefore, it is possible melting and solidify in a narrow temperature scope.
In workpiece fixative (for example, alkane), add some inorganic powdered materials sometimes, such as alumina, carbon, iron, SUS (stainless steel), carborundum, silicon or silicon nitride.Because above-mentioned, as described later, by diamond cut cutter cut place, the workpiece fixative can be cut out continuous and linear crack at workpiece.Therefore can prevent that section is offset from the precalculated position.In other words, when the inorganic powder material was present in the workpiece fixative of dispersion, described inorganic powder material had realized stoping the function of linear fracture extension.
When inorganic powdered material being dispensed in the workpiece fixative, when grinding tool or cutting tool were used in processing, inorganic powdered material can be avoided accumulating in grinding or surperficial grinding or the not good situation generation of cutting effect that makes instrument of cutting tool because of fixative effectively.That is to say, when inorganic powdered material contacts with grinding or cutting surface, can peel off the workpiece fixative on relevant grinding or cutting tool surface.
In this connection, the particle diameter of described inorganic powdered material can be from nanoscale to several millimeters.
For example, when fixing PZT blank sheet (piezoelectricity zirconium titanate), as previously mentioned, the component of the workpiece fixative that preferably adopts is the calcined bauxite in powder (particle diameter can from nanoscale to several millimeters) of the alkane and 0%～60% (percentage by weight) of 40%～100% (percentage by weight).
If the hardness to fixative has certain requirement, the component of suitable fixative can be the carborundum powder (particle diameter can from nanoscale to several millimeter) of the alkane and 0%～60% (percentage by weight) of 40%～100% (percentage by weight).
If the workpiece that is fixed is a metal material, suitable fixative component can be that the alkane of 0%～100% (percentage by weight) adds 0%～60% stainless steel powder (particle diameter can from nanoscale to several millimeters).
If the workpiece that is fixed is a glass material, suitable fixative component can be that the alkane of 40%～100% (percentage by weight) adds the glass dust (particle diameter can from nanoscale to several millimeter) of 0%～60% (percentage by weight).
If the workpiece that is fixed is the ceramic material after curing, suitable fixative component can be that the alkane of 40%～100% (percentage by weight) adds 0%～60% (percentage by weight) and the inorganic powder identical material of institute's fixation workpiece (particle diameter can from nanoscale to several millimeters).
If what be fixed is paper, the fixative component is the alkane of 100% (percentage by weight) preferably.
At said fixing agent 12, can be with Katameru Chakku (brand name U.S. Register trade mark be Thermofix).The formation of Workpiece fixing plate 10 in the present embodiment has above been described.
What next will introduce in conjunction with the accompanying drawings is a kind of method of making above-mentioned Workpiece fixing plate 10.Fig. 2 is a view of making Workpiece fixing plate 10.
What will introduce at first is the last rubber coating 20 that is used to produce Workpiece fixing plate 10.As shown in Figure 2, last rubber coating 20 comprises: one is transported roller 21, takers-in 22, one group of drive roller 21 and 22 roll drive device (figure does not show), an ozzle 23, be used for being coated with on workpiece fixative 12 to the PET plates 11 after the fusing, one drive the ozzle driver (figure does not show) of ozzle 23, a limit for height hurdle 24, be used for checking and adjust the thickness and a height adjuster of regulating limit for height hurdle 24 height (figure does not show) of the fixative 12 after the fusing of penetrating from ozzle 23.
After to be ready to thickness be 100 microns PET plate 11, can be wound on it and transport on the roller 21.This transports roller 21 and can be disposed into rubber coating 20 then.Next as shown in Figure 2, this PET plate 11 can be transferred gradually and be wound up on the takers-in 22.For the thickness place at workpiece fixative 12 is set in PET plate 11 surfaces to the slit between limit for height hurdle 24 end portion, PET plate 11 is arrived the Height Adjustment on limit for height hurdle 24 to predetermined altitude.After the height on this limit for height hurdle 24 is established, just can produce thickness from several microns to 3 millimeters workpiece fixative 12.
The surface temperature that is coated with the PET plate 11 that has melted fixative 12 is heated to the temperature that is not less than fusing point.Therefore transporting roller 21 can be heated to a temperature (can not be lower than 53 ℃ in the present embodiment) that is higher than fixative 12 fusing points.For when the workpiece fixative 12 that has melted solidifies around take up roll 22 coiling PET plates 11, preferably the temperature of take up roll 22 is reduced to the fusing point that is lower than workpiece fixative 12.
After this, when roller 21 and 22 turns round under driving separately, 11 of PET plates are carried from transporting roller 21, are winding to simultaneously on the takers-in 22.In said process, workpiece fixative 12 is heated to a temperature that is not less than its fusing point, and is injected on the PET plate 11 from ozzle 23.Be injected into fusing on the PET plate 11 fixative 12 and the PET plate 11 that just is being transmitted move together.Meanwhile, they also will be through the processing on limit for height hurdle 24.Therefore, the thickness of these fixatives 12 that move together with the PET plate will be with consistent to the slit height of limit for height hurdle 24 terminal ledges from PET plate 11.By said method, workpiece fixative 12 is applied on the PET plate 11 just.
Before be winding on the takers-in 22, the fixative 12 that has melted can be cooled under the temperature that is lower than its fusing point cooling and freeze solidly on the PET plate 11.Then, workpiece fixative 12 and PET plate 11 are rolled on the takers-in 22 together.As previously mentioned, this fixative 12 2 ℃～5 ℃ among a small circle in promptly the fusing and curdled appearance between change.Therefore there is no need to be equipped with again one and be specifically designed to the equipment that makes fixative 12 coolings and solidify.In the process of coiling PET plate 11, the fixative that has melted is cooled to one and is not higher than in the temperature of its fusing point and solidifies.In other words, only be to spray that end that fixative 12 is arranged, ozzle 23 sides just, the temperature that is heated to the fusing point that is not less than fixative 12 is just enough.Because the fixative 12 after solidifying securely attached on the PET plate 11, even the workpiece fixative 12 that solidifies is wound onto on the takers-in 22 with PET plate 11, can not separate from PET plate 11 yet.And fixative 12 does not have viscosity in addition, even under Workpiece fixing plate 10 is wound onto situation on the takers-in 22, fixative 12 can not be adhered to PET plate 11 yet.
Again backward, when be wound on PET plate 11 on the takers-in 22 by default gap length cut after, also just finished the making of Workpiece fixing plate 10 as shown in Figure 1.
Next the above-mentioned Workpiece fixing plate 10 that is to use that will introduce in conjunction with the accompanying drawings fixes the method for workpiece.Attach and also can introduce a kind of Work piece processing method.Fig. 3 is fixed on workpiece on the fixed head 10 just at processed view.
At the beginning, Workpiece fixing plate 10 is positioned on the base 30, and workpiece 40 is placed on the fixed head 10 then.Workpiece 40 to be processed hereto, its material can be potteries, clay, glass, any one in metal (aluminium pastes red copper, brass or the like) and the resin.For example, the shape of workpiece 40 can be tabular, laminar, also can be three-dimensional special-shaped.As long as can be put on the fixed head 10, any workpiece is all right.Such as for plate workpiece, can be the ceramic blank plate, the glass fiber blanket, the piezoelectricity blank flat, the electric capacity blank flat, also can by these plates each other stratiform be formed by stacking.
Then, matrix 30 is by a heater (figure does not show) heating, and in the present embodiment, matrix 30 preferably is heated to 55 ℃ to 58 ℃ temperature range, just the fusing end temp of workpiece fixative 12.As mentioned above, when fixed head 10 was heated by matrix 30, workpiece fixative 12 will melt.Therefore, workpiece fixative 12 tight adhesion that melted are on the surface of workpiece 40.
After this, when base 30 was cooled to the temperature that is not higher than fusing point, fixative 12 solidified, and workpiece 40 just has been fixed on the Workpiece fixing plate 10.Even the thickness of this fixative 12 is such as being 5 microns, the adhesion that it produces also can reach 7kgf/cm
2To 20kgf/cm
2Therefore, workpiece 40 can be firmly fixed very much.
Can fix finely too even the surface is rough three-dimensional special-shaped workpiece 40.That is to say that when fixative 12 was in solid state, workpiece 40 only had bossing to contact with workpiece fixative 12.But after fixative 12 was melted, it can enter the recessed portion of workpiece 40.For above-mentioned reasons, when workpiece fixative 12 solidified, it just can be equably contacts with the surface of workpiece 40 to be fixed.Therefore can obtain firm pull-out capacity.The surface configuration of workpiece 40 that is to say, no matter how, can both be fixed very firmly.
After treating that fixative 12 clogs fully, workpiece 40 just very ideally has been fixed on the fixed head 10, and it also just can be processed.Therefore, based on the said structure characteristics, even the cutting of workpiece 40 interval very small (such as being spaced apart 0.1 millimeter), described workpiece 40 can not be moved yet.
After workpiece 40 is fixed on the fixed head 10 as stated above, the processing beginning.In the present embodiment, workpiece 40 can be cut by ciamond grinder 50, and the latter's thickness is 0.3 millimeter, is rotating at a high speed with the speed of 2700rpm.At this moment, 12 meetings of workpiece fixative and workpiece 40 are cut together and hold.In this embodiment, when workpiece 40 was cut by ciamond grinder 50,11 of PET plates can not cut fully, and only its surface is cut open.Even cut fully but PET plate 11 and workpiece 40 are the same, also can not caused any problem.
Processing at workpiece 40 is not limited only to above-mentioned cutting.For example, can also be polishing, polishing, boring or machine cutting.
Behind workpiece 40 processed finishing, can take off it from Workpiece fixing plate 10.Especially, workpiece 40 will take off from Workpiece fixing plate 10 as described below.Because workpiece fixative 12 melts or solidifies according to temperature, when the hot water (55 ℃～58 ℃) that surpasses workpiece fixative 12 fusing end temps was poured on the workpiece 40, the fixative 12 of having combined closely on workpiece 40 will break away from.In this connection, also can immerse workpiece 40 in the hot water.At this, if introduce surfactant in hot water, fixative 12 just can be dissolved in the aqueous solution.
After fixative 12 broke away from workpiece as stated above, because its proportion is littler than water, for example, the proportion of workpiece fixative 12 was 0.8 to 0.9, and workpiece fixative 12 will swim on water (hot water) face.Therefore, workpiece 40 can be cleaned totally at an easy rate.In this connection, in order further to improve cleaning performance, can use ultrasonic cleaning method or hyperfine foam ablution.In addition, also can adopt the method that in aqueous cleaning solution, adds detergent.
As mentioned above, workpiece 40 machines.When the fixative 12 that breaks away from from workpiece 40 is recovered, regeneration and when utilizing again, workpiece fixative 12 can be used many times.In this connection, in cutting processing shown in Figure 3, wiping can be cut to pieces by ciamond grinder 50 in the surface of PET plate 11.So, can not utilize PET plate 11 once more.Yet, consider fixative 12 with workpiece 40 and PET plate 11 bondings, when fixative 12 was melted and reclaims, it can be regenerated and from new use.When fixative 12 forms very big thickness and when PET plate 11 being downcut, PET plate 11 also can be reused with described workpiece 40 is cut.
And for example going up institute releases, in the present invention, as the Workpiece fixing plate 10 of work-piece fixation clamp is by constituting as the PET plate 11 of matrix and the workpiece fixative 12 that is coated with thereon, wherein the latter's fusing with solidify and can in less than 5 ℃ temperature change scope, change.Based on said structure, when at least 5 ℃ of the variations in temperature of Workpiece fixing plate 10, its can and workpiece 40 combine like a cork.When making Workpiece fixing plate 10 change at least 5 ℃ with same way, it also can easily be separated from workpiece in 400 minutes.With this disengaging method the time, when hot water being injected into like that as described above, fixative 12 can be taken off from workpiece 40 easily.If add dispersant at this in hot water, alkane just is separated into solution.And if do not add dispersant, when solution be cooled to the fusing point that is not higher than fixative temperature the time, alkane will be floating and be set in solution surface, forms thin film.Therefore it is necessary adding this work of dispersant.
In traditional method, workpiece is by being coated in adhesive on hot peel plate or the PET plate.Yet because this class adhesive can not solidify fully, for example when with the grinding stone processing work in the rotation time, as long as the grinding stone tip touches workpiece, workpiece will move.Especially, when the cutting width of workpiece hour, when the edge of grinding stone contacted with workpiece, this motion Shaoxing opera of workpiece was strong.Therefore, above-mentioned reason has caused the processing of workpiece accurately not carry out.Yet, according to present embodiment, when fixative 12 fusing with solidify and during equably attached to workpiece 40 surfaces, workpiece 40 can very anchor on the fixed head 10 securely.This just may prevent that workpiece 40 is from fixed head 10 motions.Workpiece 40 also can be very accurately processed.
In addition, aforesaid, the workpiece 40 in the present embodiment is not fixed by adhesive by conventional method, the substitute is a kind of can be in very little temperature change scope (2 ℃ to 5 ℃) melt repeatablely and solidify the workpiece fixative 12 of conversion.Therefore unlike with former the sort of be matrix with the adhesive tape, the method for coated with adhesive, the workpiece material that is applicable to this method is without any restriction.And be as matrix by PET plate 11 in the present embodiment.
Subsequent that will introduce is second embodiment, in this embodiment, only introduces the difference of itself and first embodiment.On the Workpiece fixing plate 10 of this embodiment,, the coating patterns that is coated in the fixative 12 on the PET plate is a striated.
Fig. 4 is the plane of second enforcement of work-piece fixation clamp among the present invention.As shown in the figure, on the Workpiece fixing plate 10 of this embodiment, workpiece fixative 12 is coated with striated and solidifies on PET plate 11.Each width of fringe of fixative 12 can freely be set.For example, preferably design by this way, its width is between 0.05 millimeter to tens millimeters.The fringe spacing is then generally within 0.1 millimeter to several millimeters.Stripe direction can be vertically, also can be horizontal.
Fig. 5 is the view of Workpiece fixing plate 10 in the construction drawing 4.In the present embodiment, in last rubber coating 20, when the height adjuster of regulating limit for height hurdle 24 height when being used to of not showing drove limit for height hurdle 24, the fore-end on limit for height hurdle 24 contacted with PET plate 11 in during setting or separates.For above-mentioned reasons, as illustrated in fig. 5, provide part that scribbles fixative 12 and the part that is not coated with fixative 12 on the surface of PET plate 11.So just can form the fixative 12 of striated among Fig. 4.
And when striated fixative 12 after PET plate 11 surface forms, no matter the latter is bent or is reeled, the pressure effect that fixative 12 produces can guarantee that all it can not separate with PET plate 11.Owing to can not influence the effect that fixative adheres to PET plate 11, the conversion arbitrarily on demand of the concrete layout shape of fixative 12.
It is subsequent that will introduce is the 3rd embodiment, this explanation only introduce its with before the difference of embodiment.Characteristics of this group embodiment are to form the groove on the PET plate 11 of Workpiece fixing plate 10.
Fig. 6 A is the 3rd enforcement plane of PET plate 11 among the present invention to 6C.Fig. 7 is that PET plate shown in Fig. 6 A is along the sectional view of cross section A-A.
In the PET plate 11 shown in Fig. 6 A,, just formed the groove 11a of cruciform shape because groove is simultaneously manufactured on vertical and horizontal both direction.In the present embodiment, as shown in Figure 7, in the present embodiment, groove 11a only is formed on the one side of PET plate 11.For example, the degree of depth of groove 11a is 1 micron to 500 microns.
These grooves 11a can produce by a surface with the rough PET plate 11 of sand paper (model is from #10 to #100) mill.Specifically, the one side that is exactly PET plate 11 laterally with is vertically constantly being rubbed on the both direction by sand paper, and shape right-angled intersection connected in star 11a as shown in Figure 6A will produce.
In the PET plate 11 shown in Fig. 6 B, demonstration be waveform groove 11a on vertically.And in the PET plate 11 shown in Fig. 6 C, demonstration be and the oblique line X-shape groove 11a that vertically is 45.
Be to use described sand papering method before equally, waveform groove 11a on Fig. 6 B and the grid groove 11a on Fig. 6 C form in PET plate 11 surface finish by sand paper.
Especially, groove 11a is formed on the face of PET plate 11, makes coated abrasive roll to make groove by the rotation of this roller on PET plate 11 and friction then on a roller.
That is to say, when volume has the roller of sand paper, during along the longitudinal with the one side of the lateral rotation of this vertical quadrature and wiping PET plate 11, just can on the PET plate, form grid groove 11a as shown in Figure 6A.
The roller that sand paper arranged when volume the roller word axially on be driven simultaneously that roller also rotates, PET plate 11 is gone in the sand paper wiping, forms the waveform groove 11a on the PET plate 11 shown in Fig. 6 B.
And when volume when the roller turn of sand paper is arranged, can roller axially and and PET plate 11 vertically between keep the relation at acute angle or obtuse angle, the sand paper wiping is gone in the PET plate 11, thereby forms the oblique line X-shape groove 11a shown in Fig. 6 C on PET plate 11.
Thus, even sand paper not on roller, also can directly use sand paper a surperficial roughening of PET plate 11.
After the manufacturing of the groove 11a on the PET plate 11 was finished, the fixative 12 after the fusing will be applied on the PET plate 11 by Fig. 2 and way shown in Figure 5, just can produce Workpiece fixing plate 10 as shown in Figure 1 and Figure 4.
As above release, when groove 11a is provided, just determined the surface area of PET plate 11 one sides on PET plate 11.When workpiece fixative 12 is applied on the PET plate 11 so that these grooves 11a can filling workpiece fixative 12 time, can guarantee the one side of PET plate 11 and the contact area between the fixative 12, fixedly the pull-out capacity of 12 of PET plate 11 and fixatives has strengthened.Therefore can prevent the disengaging of fixative 12 effectively from PET plate 11.
That and then will introduce is the 4th embodiment, this explanation only introduce its with before the difference of embodiment.The characteristics of this embodiment are to have added layer of adhesive 13 in order to strengthen the bonding force of 12 of PET plate 11 and workpiece fixatives between them.
Fig. 8 A is the 4th an enforcement plane of Workpiece fixing plate 10 among the present invention.Fig. 8 B is that fixed bed shown in Fig. 8 A is along the sectional view of section B-B.
Shown in Fig. 8 B, the Workpiece fixing plate 10 in the present embodiment comprises: PET plate 11; Be coated in the adhesive 13 on the PET plate 11 and be coated in workpiece fixative 12 on the adhesive phase 13.
This adhesive layer 13 can make fixative 12 and PET plate 11 closely combine.This adhesive 13 can be an acrylate glue, and cellulose gum also can be an epoxide-resin glue.It can be applied on the PET plate 11 equably, and thickness can be from 1 micron to 200 microns.
Shown in Fig. 8 A, described adhesive 13 has been coated on the face of PET plate 11 (figure does not show).Can be coated with last layer thickness on this adhesive 13 can be at the workpiece fixative 12 between 1 micron to 1 millimeter.If usefulness is acrylate glue 13, then before coating fixative 12, must make adhesive 13 crosslinked with high temperature or ultraviolet irradiation earlier.If not crosslinked, coating (fixative 12) will be mixed mutually with adhesive 13, just can not give play to the effect of anticipation.After crosslinked, coating (fixative 12) just can closely be fixed, and also just can give play to the function of anticipation.
Inventors detect the required separating force of Workpiece fixing plate that separation is made up of said structure 10 with terminal partition method (T-PEELING).Here introduce terminal partition method earlier.Heated parts fixative 12 makes it fusing, and on the matrix attached to fixed head 10.The end of fixed head 10 will be used to test the size of separating required power, and this method is terminal partition method.Its measured separating force is exactly the needed power of matrix of separating fixative and fixed head 10.
When detecting with said method, detected object is divided into two classes: be respectively to scribble the fixed head 10 of adhesive 13 and the fixed head 10 of coating adhesive 13 not.Experimental result is as follows, and separating not, the fixed head 10 required terminal separating forces of coating adhesive 13 are 0.1 N.And on the other hand, separate the fixed head 10 required terminal separating forces that scribble adhesive 13 and do not wait from 0.2 N to 10 Ns.Can believe that thus adhesive 13 can make PET plate 11 and workpiece fixative 12 combine securely.
As shown in this embodiment, using Workpiece fixing plate 10, provide under the situation of adhesive 13 between PET plate 11 and workpiece fixative 12 it on, when workpiece being fixed on the workpiece fixative 12, only the temperature that melts in fixative 12 generations heats and gets final product.And to make workpiece when fixative 12 breaks away from, as long as on workpiece and fixative 12, inject the hot water that can only make fixative 12 fusings, both are broken away from, if replace water filling with the way that heats certainly, and equally only melt fixative 12, effect also is the same.
As above release, adhesive 13 is coated on the one side of PET plate 11, and fixative 12 is coated in again on the adhesive 13.The bonding force of 13 in PET plate 11 and adhesive has strengthened thus.So can effectively prevent separating of fixative 12 and PET tape board 11.
That will introduce below is the 5th embodiment, this explanation only introduce its with before the difference of embodiment.The characteristics of this embodiment are that it has used hot melt material to replace adhesive 13 among the 4th embodiment.
In other words, not with the adhesive 13 shown in Fig. 8 A and the 8B, the substitute is a kind of hot melt material, although be the same on the function.Hot melt material in the present embodiment can be rosin or epoxy resin.
After above-mentioned hot melt material was heated fusing, they can be coated onto on the PET plate 11, and and then were cooled and solidify.After this, fixative 12 just can be coated onto on the hot melt material.With work-piece fixation clamp and Fig. 8 A that this method is made, the striking resemblances shown in the 8B.
The terminal partition method of using in the 4th embodiment detects separating force and also is used to detect this type of stationary fixture.The result who obtains is consistent with the 4th embodiment's.
In the present embodiment, in the time will being fixed on workpiece on the fixative 12, heating-up temperature must be controlled at fixative 12 is taken place in the scope of fusing.When will workpiece when fixative 12 takes off,, both being broken away from as long as on workpiece and fixative 12, inject the hot water that fixative 12 is melted.
As above release, hot melt material also can make PET plate 11 and workpiece fixative 12 combine securely.
Subsequent introduction be the 6th embodiment.After the PET plate had been coated with acrylate glue, the megathermal fixative 12 that a kind of fusing point can reach 72 or 85 had been coated onto on the acrylate glue.And being the fixative 14 of 53 or 55, another fusing point has been coated on this fixative 12.
In this embodiment, when the fixative 12 that is 72 ℃ or 86 ℃ to temperature was coated onto on the adhesive 13, the heat that its produces not too can make adhesive 13 sex change.Equally, when the fixative 14 of coating low form, as the high temperature modification fixative 12 of place mat fusing or sex change can not take place yet.Fixative 12 and 14 in the present embodiment, their fusing initial temperature differs at least 15 ℃, and therefore when coating low form fixative 14, owing to not melting of high temperature modification fixative 12, low form fixative 14 can be coated with well.
Do following introduction in this character with regard to two kinds of fixatives 12 and 14:
(A) the low form fixative 14
<53℃>
The fusing initial temperature is 52.5 ℃, and the fixative component is referring to table (2).The fusing end temp is 53.7 ℃.
<55℃>
The fusing initial temperature is 54.6 ℃, and the fixative component is referring to table (3).The fusing end temp is 55.6 ℃.
(B) the high temperature modification fixative 12
<72℃>
The fusing initial temperature is 72.1 ℃, and the fixative component is referring to table (4).The fusing end temp is 73.4 ℃.
<86℃>
The fusing initial temperature is 86.2 ℃, and the fixative component is referring to table (5).The fusing end temp is 87.9 ℃.
Specifically introduce the technical advantage that in the present embodiment fixative 12 and 14 is connected together with doing hereinafter.
Suppose to being processed, finish when will be when PET plate 11 takes off that available injection can only make the method for the hot water that fixative melts remove PET plate 11 it in processing by the workpiece that sticked.But according to above situation, the adhesive 13 that is made of acrylic resin can cling workpiece, even mixes with it.
On the other hand, according to present embodiment, low form workpiece fixative 14 is coated in the side by workpiece, and high temperature modification fixative 12 is coated in the side by adhesive 13.Can only make 14 fusings of low form fixative when injecting, and after can not making the hot water of high temperature modification 12 fusings, just have only low form fixative 14 to melt, high temperature modification fixative 12 is constant.
Therefore, owing to also scribble one deck high temperature modification fixative 12 on the adhesive 13 in the present embodiment, form the component of adhesive 13, just the acrylic resin in the present embodiment just can not adhere to surface of the work, can not mix mutually with it yet.Especially, if workpiece is for introduced contaminants ten minutes sensor sensitive,, just preferably use the work-piece fixation clamp of the tool laminate patch type fixative in the present embodiment such as silicon semiconductor.
At last, also have an embodiment to introduce.In above-mentioned all embodiment, the matrix of accepting fixative 12 all is a PET plate 11.In fact, the material of matrix is not limited only to this.It can also be cloth, paper, burlap, nonwoven, sheet metal or metallic plate.The matrix made from these materials agent 12 coatings that also can both be fixed also can both be formed stationary fixture fixation workpiece 40.
The size of the fixed head 10 that occurs in above-mentioned introduction is an example, and virtually any size can use in fact.After having coated fixative 12 when PET plate 11, it just can be cut into suitable size according to the needs of workpiece.Do not cut also passablely, but the requirement that can be rolled into drum-shape must be satisfied.
The main component of above-mentioned workpiece fixative 12 is an alkane.Also can use the fixative of main component in fact as polyethylene glycol.
For above-mentioned Workpiece fixing plate 10, their PET plate 11 has only one side to scribble fixative 12, and fixative 12 can be coated in the two sides of plate 11 in fact.
In the 3rd embodiment that mentions before, the groove 11a on the PET plate 11 has only grid, waveform and oblique line X-shape.The shape of groove 11a is not limited only to this in fact.For example, groove 11a can be a linear, shaped form, spot distribution shape, waveform, cruciform shape (grid), oblique line X-shape (oblique line shape) or be formed by stacking by the intersection on three different directions.As for the instrument of making these grooves, can be sand paper or cutter and so on.
Also can be added on the PET plate 11 of the band groove 11a among the 3rd embodiment with hot melt material at the adhesive of using among the four, the five embodiment 13.These grooves of filling 11a's is exactly to be coated on adhesive 13 on the PET plate 11 with hot melt material like this.
Under the situation that fixative 12 is coated onto on the PET plate 11, the fixative 12 that has melted is from ozzle 23 ejaculations.But, also can make Workpiece fixing plate 10 on the PET plate 11 by fixative 12 is printed to.Use this method, can on PET plate 11, make the fixative 12 of band spot distribution type as shown in Figure 9 equally.The size and the shape of point can design on demand voluntarily.
Certainly the concrete layout shape of fixative 12 is not limited only to top point and the striped of saying, it can also be netted, oblique line shape, wave wire or the combination of these shapes.Its thickness on PET plate 11 also can be unified.
In the above-described embodiments, PET plate 11 is wound onto on roller 21 and 22 so that form Workpiece fixing plate 10.Yet, when making Workpiece fixing plate 10, do not need to use roller 21 and 22.For example, when the fixative 12 that has melted was painted on (or being imprinted on) and has cut into PET plate 11 surperficial of preliminary dimension, Workpiece fixing plate 10 perhaps formed.In this case, matrix does not resemble PET plate 11, that is to say, in this case, matrix is not a plate shape, then can make work-piece fixation clamp to the method for matrix surface by the fixative that direct sprinkling has been melted.
Above pass through a plurality of specific embodiments and at length introduced the present invention.But, should know that without departing from the spirit and scope of the present invention, those skilled in the art can also carry out multiple variation and improvement with regard to the present invention.
