Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of rod sticky device of the present invention, comprises crystal bar 1, brilliant supporting plate 4, ground glass 3, sheet glass 2, passes through together with glue fixed bonding between described ground glass 3 horizontal positioned with described brilliant supporting plate 4.Described crystal bar 1 horizontal positioned and be fixedly bonded on the upper surface of described ground glass 3 by glue, the inner surface of described sheet glass 2 is fixedly connected with the end end face of described crystal bar 1.The quantity of described sheet glass 2 is two pieces, and two blocks of described sheet glass 2 are fixed bonding with the two ends end face of described crystal bar 1 respectively by glue, and the bottom of sheet glass 2 described in every block and the upper surface of described ground glass 3 carry out glue fixed bonding.
A kind of sticky stick method of the present invention, comprises the steps: 1) first by horizontal for ground glass 3 fixed bonding on brilliant supporting plate 4; 2) then by crystal bar 1 horizontal positioned, and fixed bonding is on ground glass 3; 3) on the end face at the two ends of crystal bar 1, stickup one block of sheet glass 2 is fixed respectively, wherein, the inner surface of described sheet glass 2 nestles up the end face at the two ends of described crystal bar 1, the bottom of described sheet glass 2 is close to the upper surface of described ground glass 3, sheet glass 2 is fixedly pasted onto on the two ends of crystal bar 1, not only can reduce the outwards swollen active force that crystal bar 1 is subject in cutting process, can also play a supporting role to the silicon chip at crystal bar 1 two ends; 4) entirety that fixed bonding is good is put on multi-line cutting machine completes cutting processing.
Carrying out above-mentioned steps 3) operation, by masking tape and glue, described sheet glass 2 is pasted respectively the end face at the two ends of described crystal bar 1.During stickup, first by the position of paper self-adhesive tape fixing glass sheet 2 and crystal bar 1, and then between sheet glass 2 and crystal bar 1 spreading glue.After the glue curing that described sheet glass 2 is bonding with described crystal bar 1, the described adhesive tape of tearing between described sheet glass 2 and described crystal bar 1, adhesive tape of tearing drops in cutting equipment to lose viscosity after preventing adhesive tape wet by mortar bubble when crystal bar 1 carries out slice processing.Bonding crystal bar 1 is put on multi-line cutting machine and carries out slice processing, when multi-line cutting machine is at the half of cutting processing to crystal bar 1, the mortar that multi-line cutting machine is brought into will produce the active force outwards swollen along crystal bar 1 two ends, when after the bonding sheet glass 2 in the two ends of crystal bar 1, this active force just acts on the sheet glass 2 at crystal bar 1 two ends after the blocks of polysilicon chip at crystal bar 1 two ends, sheet glass 2 bears this active force and supports the two ends of crystal bar 1 simultaneously, effective minimizing crystal bar 1 two ends produce flake products end to end in cutting process, improve the yield rate that crystal bar 1 section is produced.
Its concrete operation step is as follows: pasted by crystal bar 1 on the ground glass 3 on brilliant supporting plate 4, then the bonding one block of sheet glass 2 of difference on the two ends end face of crystal bar 1, the bottom of sheet glass 2 is bonded on the upper surface of ground glass 3, make the two ends of sheet glass 2 pairs of crystal bars 1 play a supporting role simultaneously, sheet glass 2 needs time bonding with crystal bar 1 to be fixed by paper self-adhesive tape, tear paper self-adhesive tape again with after bonding glue curing, finally the bonding crystal bar 1 completed is placed on multi-line cutting machine and carries out slice processing.
The present invention discloses a kind of rod sticky device and sticky stick method thereof, this invention mainly add at the two ends of crystal bar 1 in the process of sticky stick one can to the parts that the silicon chip at crystal bar 1 two ends is played a supporting role in process, bear simultaneously suffered by the silicon chip of crystal bar 1 two ends to outer expansion force, thus reduce the quantity of sheet end to end in whole slice processing process, serve the effect improving the rate that manufactures a finished product, method is simple, easy to operate, improves economic benefit.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
