[specific embodiment]
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.A lot of details have been set forth in the following description so that fully understand the present invention.But the present invention can implement much to be different from alternate manner described here, and those skilled in the art can do similar popularization under the situation of intension of the present invention, so the present invention is not subjected to the restriction of following public concrete enforcement.
Secondly, the present invention utilizes schematic diagram to be described in detail, when the embodiment of the invention is described in detail in detail; for ease of explanation; the profile of expression device architecture can be disobeyed general ratio and be done local the amplification, and described schematic diagram is example, and it should not limit the scope of protection of the invention at this.The three dimensions size that in actual fabrication, should comprise in addition, length, width and the degree of depth.
Please consult Fig. 1 and Fig. 2 simultaneously, the glass fixture that is used for clamping glass plate 200 100 of an embodiment comprises non-magnetic conduction framework 10, a plurality of magnet 20 and magnetic conduction framework 30.
Non-magnetic conduction framework 10 is suitable with the shape of glass plate 200, and in the present embodiment, glass plate 200 is a rectangle, and therefore non-magnetic conduction framework 10 is the rectangle frame.The material of non-magnetic conduction framework 10 is the non-magnetic material, is preferably copper, copper alloy, aluminium, aluminium alloy, titanium or titanium alloy.
A plurality of magnet 20 evenly distribute and are arranged on the non-magnetic conduction framework 10.In the present embodiment, a plurality of magnet 20 equally spaced are embedded in the groove (indicate) of non-magnetic conduction framework 10 1 sides, and the magnetic pole of each magnet 20 and magnetic conduction framework 30 is surperficial relative.Magnetic conduction framework 30 is passed in the magnetic line of force concentrated area of each magnet 20 that can make like this, adds the attraction of 20 pairs of magnetic conduction frameworks 30 of strong magnet.In more preferred scheme, as shown in Figure 3, the polarity of the magnetic pole of adjacent magnets 20 is opposite.For example, the N utmost point of one of them magnet is last, and the S utmost point is down, another then adjacent magnet with this magnet then be the S utmost point last, the N utmost point is down.This setup can prevent that the magnet of identical polar from leaning near and magnetic counteracting that cause, further adds the attraction of 20 pairs of magnetic conduction frameworks 30 of strong magnet.Magnet 20 is preferably made by samarium-cobalt alloy.
The shape of the shape of magnetic conduction framework 30 and non-magnetic conduction framework 10 is basic identical.Magnetic conduction framework 30 is made by permeability magnetic material, is preferably by iron, ferroalloy, nickel or nickel alloy and makes.
During use, non-magnetic conduction framework 10 is placed vertically, and glass plate 200 then is held between non-magnetic conduction framework 10 and the magnetic conduction framework 30 vertically because of the magnetic force of magnet 20.
Above-mentioned glass fixture 100 has following beneficial effect: at first, this glass fixture 100 can cooperate processing thickness less than 0.3 millimeter glass, reduce investment outlay greatly cost and production cost with original vacuum magnetic-control sputtering coating film production line.The chucking power that magnet 20 is produced is perpendicular to the power of glass planar, this power is produced by magnetic force, and be evenly distributed in very much the neighboring area that is held glass plate 200, because this regional glass surface micro-crack is extremely few, added power causes micro-crack to cause into may significantly reducing of crackle, and the end regions discord object of assembling micro-crack in a large number contacts, thereby be not subjected to any power, therefore can avoid micro-crack (conventional brace is often only stressed in the end, and power is easy to concentrate on the part) because of impulsive force causes.Glass plate 200 is more flexible along the plane in the heating and cooling process, avoids stress to concentrate and breakage; Glass plate 200 on end transmits, and can avoid during plated film molecule to fall glass surface in vacuum chamber and cause pinprick on the film.
See also Fig. 4, the glass conveyer 300 of an embodiment comprises transfer cart 400 and the glass fixture of being located on the transfer cart 400 as shown in Figure 1 100.
Transfer cart 400 comprises the support frame 40 of vertical placement and is located at the wheel 50 of support frame 40 bottoms.
The shape rectangle of support frame 40, its middle part is formed with the spatial accommodation 41 of accommodating glass fixture 100.Spatial accommodation 41 be shaped as the rectangle identical with non-magnetic conduction framework 10.The position that support frame 40 is positioned at the upper and lower both sides of this spatial accommodation 41 is respectively equipped with two positioning convex column 43.The lower limb correspondence is provided with the locating slot (figure does not show) of accommodating positioning convex column 43 on the non-magnetic conduction framework 10.Be appreciated that positioning convex 43 also can be located on the non-magnetic conduction framework 10, this moment locating slot then correspondence be opened on the support frame 40.
Be positioned on two positioning convex column 43 of non-magnetic conduction framework 10 upsides and also be arranged with spring 45 respectively.
See also Fig. 5, the glass fixing means of an embodiment comprises the steps:
Step 1, provide a platform 500.This platform 500 has the surface 501 of level.Surface 501 is provided with three not alignment pins 503 of conllinear.In the present embodiment, the line between these three alignment pins 503 forms a right angle.The quantity that is appreciated that alignment pin 503 also can be above three.
Step 2, non-magnetic conduction framework 10 is placed on the platform 500, and by this three alignment pins, 503 location.Because non-magnetic conduction framework 10 is roughly rectangle, therefore can comparatively firmly be fixed on the platform 500 by arranging rectangular three alignment pins 503.
Step 3, glass plate 200 is placed on the non-magnetic conduction framework 10, and aligns with non-magnetic conduction framework 10 by these three alignment pins 503.
Step 4, magnetic conduction framework 30 is placed on the glass plate 200, and aligns with non-magnetic conduction framework 10, form the glass fixture 100 of clamping glass plate 200 by these three alignment pins 503.Be provided with a plurality of magnet 20 owing to evenly distribute on the non-magnetic conduction framework 10, so glass plate 200 can be held in because of the magnetic force of magnet 20 between non-magnetic conduction framework 10 and the magnetic conduction framework 30.
Step 5, glass fixture 100 is taken off from platform 500, be fixed to vertically on the transfer cart 40 then.Specifically, glass fixture 100 is taken off from platform 500 carefully, two locating slots of non-magnetic conduction framework 10 top edges are sheathed on respectively are positioned at two positioning convex column 43 that support frame 40 is positioned at the upside of this spatial accommodation 41, further compress spring 45.Two positioning convex column 43 of the downside of this spatial accommodation 41 are alignd with two locating slots of non-magnetic conduction framework 10 lower limbs, under the effect of the screen resilience of gravity and spring 45, two positioning convex column 43 can very accurately enter in two locating slots smoothly, thereby make glass fixture 100 comparatively stably be fixed in transfer cart 40.
Be appreciated that spring 45 also can omit.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
