Description
1, technical field:
The utility model is the bonder that high density compact discs such as a kind of DVD of being used for, HD-DVD are produced, and belongs to the renovation technique that high density compact disc is produced bonder.
2, background technology:
DVD; The epochmaking process procedure that high density compact discs such as HD-DVD are produced is two thin discs that have high density hole groove information must be bonded together by specific mode, and industry slang is called " BONDING ".In order to reach certain speed of production, and guarantee the high homogeneity of bondline thickness, and avoid the generation of the residual and warpage of bubble, and various countries equipment manufacturers invention is for many years designed the bonding machine of many moneys and is realized this technological process, and concluding these technology modes has following several big class:
1) gap injecting glue method: two discs are close up and down, the very little gap of middle reservation, a very thin syringe needle goes into to the center to begin injecting glue from middle Shen, make glue point touch two discs up and down simultaneously, and rotation allows inner ring evenly stick glue up and down at a slow speed.Syringe needle is extracted the back out and is full of whole gap by centrifugal force by glue by high speed rotating.Though this technology can avoid bubble to produce to a certain extent, control accuracy requires very high, and action is meticulous, and speed is slower, to the effectively control of uniformity coefficient shortage of glue-line.Use the equipment vendors of this technology to have: Dutch ODME company, German STEGA company etc.
2) two-sided dotting glue method: two card inner rings are put gluing respectively, adjacent to each other with the angle of an inclination then, the bubble generation is repelled in the slow fusion of spreading over a whole area from one point by glue face and glue face, and is full of whole card gap by centrifugal force by glue by high speed rotating again.The relative merits of this technology and last a kind of too big difference that do not have, just control is got up comparatively simple.Use the equipment vendors of this technology to have: Japanese Sony Corporation, Taiwan ADM company etc.
3) static Method for bonding: allow the glue of punctuating in the card earlier, while, two cards charged into the static charge of opposed polarity respectively, strengthen the fusion of card and glue face and repel bubble producing by attractive force mutual between the electric charge, finally still be full of whole card gap by centrifugal force by glue by high speed rotating.This technology is the progress of above two kinds of technology modes, but still only depends on centrifugal force that glue is diffused into whole card, and the control of the uniformity coefficient of glue-line still lacks, and static residual on disc caused many influences to back operation production.Use the equipment vendors of this technology to have: German SINGULUS company, the special company of Taiwan water chestnut etc.
4) conventional vacuum is bonding: under vacuum condition, two discs that are coated with full glue are in advance pressed together with the strength that cylinder or motor provide.Because vacuum cavity is inner cylinder or power motor (because of meeting influences vacuum tightness, and strengthened the cavity influence and bled the time) can not be installed, so power all is to transmit by dynamic sealing device, thereby mechanism's complexity.Though this technology can effectively avoid bubble to produce, because the acting force of pressing for once, and can not be distributed to whole card equably, the uniformity coefficient of glue-line still lacks effective control.Use the equipment vendors of this technology to have: Switzerland UNAXIS company, Japanese SHIBAURA company etc.
