Embodiment
Below will and describe in detail and clearly demonstrate spirit of the present invention with diagram, as the person skilled in the art after understanding embodiments of the invention, when can be by the technology of teachings of the present invention, change and modification, it does not break away from spirit of the present invention and scope.
The present invention discloses a kind of platform and a kind of method of adsorbing glass substrate in order to the phenomenon of improving the glass substrate warpage, see Fig. 1, shown in Figure 2, be applicable in the production board of liquid crystal indicator (LCD), this produces on the edge of board in order to crimping drive circuit chip 21 to one glass substrates 2, at least comprise a platform 1, one installing zone 3 and two Filtting devices 31, Filtting device 31 is exemplified as mechanical arm, this platform 1 is located at a side of this installing zone 3 versatilely, and between above-mentioned two Filtting devices 31, can be between above-mentioned two Filtting devices 31, move towards this installing zone 3 versatilely, or away from this installing zone 3, and the one side of this platform 1 can be placed a glass substrate 2, and utilize platform 1 that glass substrate 2 is adsorbed in, wherein the area of glass substrate 2 greater than, equal this platform 1, when the area of glass substrate 2 during greater than this platform 1, about 8 to 12 millimeters of the edge that its each edge exceeds this platform 1.Alternatively, the edge of the edge of this glass substrate 2 and this platform 1 is at a distance of 8 millimeters to 12 millimeters.
So, glass substrate 2 on this platform 1 when this installing zone 3 moves, the one edge can be driven so far on the installing zone 3, so that the glass substrate 2 on (being crimping bonding) drive circuit chip 21 these installing zones 3 is installed; And produce board to glass substrate finish drive circuit chip 21 is installed after, glass substrate 2 can be driven away from this installing zone 3 on this platform 1, the Filtting device 31 of these platform 1 both sides is contacted two corresponding edges of glass substrate 2 again, and make glass substrate 2 break away from this platform 1.
For avoiding glass substrate 2 on this platform 1, to have the phenomenon generation that perk is curled, see the 1st, shown in 3 figure, this platform 1 just connects a vacuum attraction machine 4, in order on this platform 1, to attract glass substrate 2, make glass substrate 2 smooth as much as possible on this platform 1, wherein platform 1 comprises a body 11 and an extension 12 at least, has an adsorption plane 111 on the body 11, and extension 12 is positioned at a side of body 11, its two ends stretch out towards two corresponding end of body 11 respectively, the tool first exhausting hole 112 on the adsorption plane 111, the extension 12 tools second exhausting hole 123, first, two exhausting holes 112,123 connect vacuum attraction machine 4 respectively, when making glass substrate 2 overlapping (overlap) on body 11 and extension 12, vacuum attraction machine 4 can be via first, two exhausting holes 112,123 modes with vacuum suction are carried out exhausting to glass substrate 2, in order to absorption glass substrate 2, so that drive circuit chip 21 is installed.
Yet, to glass substrate 2 install the step of drive circuit chip 21 can glass substrate 2 and relatively moving of drive circuit chip 21 carry out, though present embodiment is being example towards installing zone 3 mobile platforms 1, carry out but also can move drive circuit chip 21 towards platform 1, or while mobile platform 1 and drive circuit chip 21.
In one embodiment of the invention, see Fig. 1, Fig. 3 and shown in Figure 4, the body 11 of this platform 1 is a rectangle, and the adsorption plane 111 on it is a circle, and arrange in radial mode in each the first exhausting hole 112 on the adsorption plane 111.Extension 12 is the rectangle long than body 11 1 sides, and be connected in a side of body 11, after making that the two ends 121,122 of extension stretch out the several times (as: 25% to 40%) of body 11 length towards two corresponding end of body 11 respectively, form the T font substantially with body 11, and each second exhausting hole 123 is arranged in equidistantly on the extension 12.So, if the length L 1 of body 11 is about 198 millimeters to 202 millimeters, when width W 1 is about 153 millimeters to 157 millimeters, then the length L 2 of extension 12 just is about 323 millimeters to 327 millimeters, width W 2 and is about 58 millimeters to 62 millimeters.
When glass substrate 2 is positioned on body 11 and the extension 12, each first exhausting hole 112 on more than body 11 can be for attracting glass substrate 2, and near the glass substrate 2 two curling ends that are upturned, also can attract the glass substrate 2 two curling ends 22 that are upturned, to improve the degree that glass substrate 2 perks are curled by providing near the second exhausting hole 123 at extension 12 two ends 121,122.In present embodiment, the be upturned distance of two curling ends 22 of the first exhausting hole 112 and the glass substrate 2 of adsorption plane 111 outermost of body 11 respectively is 195 millimeters, and extension 12 two ends 121,122 is 75 millimeters and 50 millimeters with glass substrate 2 curling two ends, 22 distances that are upturned respectively, and when only utilizing the first exhausting hole 112 to provide to attract two ends 22 that glass substrate 2 is upturned curling, its glass substrate 2 be upturned two curling ends 22 degree greater than 2 the degree (degree), utilize the first exhausting hole 112 to add the second exhausting hole 123 and provide when attracting glass substrate 2 two ends, the degree that glass substrate 2 perks are curled will be less than 2 degree (degree), therefore, the first exhausting hole 112 adds that the second exhausting hole 123 than when only utilizing the first exhausting hole 112 that attraction two ends 22 that glass substrate 2 is upturned curling are provided, has more the effect of improving glass substrate 2 perk amount of crimp.
Yet, what deserves to be mentioned is, extension 12 outward extending two ends 121,122 length L 21, L22 also unrestrictedly must equate or not wait, can be changed in response to the environment of producing in the board, for example the outward extending end 121 of extension may touch other equipment of producing in the board, and obstruction is produced the running of board, therefore, can revise extension 12 outward extending end length 121, two ends 121,122 length L 21, the L22 that makes extension 12 extend outwardly is respectively 48 to 52 millimeters and 73 to 77 millimeters.
The emphasis of extension is at its two ends that extend outwardly 121,122, therefore, in the another embodiment of the present invention, see Fig. 5, the homonymy of body 11 is with two extensions 12 ', stretches out towards one of 11 liang of corresponding end of body separately, makes between two extensions 12 ', the position of corresponding body 11 is provided with a breach 124, with material cost or the convenient ornaments of producing other equipment in the board that reduce platform 1.
Various embodiments of the present invention are example with the absorption glass substrate, but are not limited to this, and all need all can use platform of the present invention and method in order to the phenomenon of improving the work package warpage, and work package for example can be wafer or other semiconductors or industrial element.
And the present invention discloses among as above each embodiment; be not in order to limiting the present invention, anyly be familiar with this operator, without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, thus protection scope of the present invention should with enclose claim was defined is as the criterion.
