Background technology
CD is owing to have the storage density height, volume is little, the storage period limit for length, with low cost, advantages such as compatible height and error rate are low, become the main flow of present optical information recording medium, technically, digital video disk (Digital Video Disc, be called for short DVD) be intended to cover home entertaining with a kind of single digital format, computer and information commercial affairs, it has been substituted laser disc, and obtained from all electronic enterprises and computer hardware enterprise, the support of film and music studio, become the most successful storage medium on the CD storage technique history, it makes information flow more convenient, therefore plays more and more important effect in social life.
Along with improving constantly of people's personal consumption level, the consumption viewpoint constantly develops, more high-resolution films occur, HDTV (High Definition TV, be called for short HDTV) will popularize in the whole world, because message transmission rate (the Data Transfer Rate of HDTV in the digital satellite broadcasting, abbreviation DTR) is at least 23Mbps, the twice that is present DVD speed is many, so if store the high image quality image and sound program (standard of industry is 133 minutes) that surpasses two hours HDTV grades, the active volume of recording disk must surpass more than the 20GB, so people are more and more higher to the capacity requirement of optical disc storage.
Blu-ray Disc (Blu-ray Disc, BD) be a kind of CD storage technique of vast capacity, in order to store the data of high-quality audio-visual and high power capacity, Blu-ray Disc utilizes wavelength to read and write data for the blue laser of 450nm, and traditional DVD utilized is the red laser of wavelength for 650nm, the short more laser of wavelength as a rule, can on unit area, write down or read more information, therefore the blue light technology has improved the memory capacity of CD greatly, Blu-ray Disc has 5 times of storage capacities to existing DVD CD specification, not only can be applicable to record, erasable or play HD high definition image, also can be used for simultaneously more googol content of memory capacity, because it has higher recording capacity and density, be applicable to the requirement of data storage on the modern high information quantity, so the blue light memory technology is one of mainstream technology of optical storage technology of future generation.

Below in conjunction with Fig. 5-Fig. 8, the glue supply method that uses glue feedway 1 of the present invention is elaborated, after system starts working, check earlier whether the 5th sensor 101a in the recycling bin 10 has signal, if have the glue that then illustrates in the recycling bin 10 full, then earlier the glue vacuum in the recycling bin 10 sucked filter vat 30 inner filtrations; Do not have glue in it if the 5th sensor 101b in the recycling bin 10 has signal then to illustrate, then extract the glue in the Raw material pail 20; Glue vacuum in recycling bin 10 or the Raw material pail 20 are sucked carry out filtration first time in first filter vat 31; the glue filtrator of glue in it filters the back and sucked by vacuum and carry out the filtration second time in second filter vat 32; in second filter vat 32, after the glue filtrator filters, sucked in the 3rd filter vat 33 and filter for the third time by vacuum; after glue filtrator in the 3rd filter vat 33 filters, obtain cleaning and use after clean protection glue is waited for de-bubble.
Then, open first combination valve 411 at glue-feeder place of the first de-bubble bucket 41 and the solenoid valve 413 at vacuum gas port place, pumped vacuum systems vacuumizes processing to the first de-bubble bucket, 41 inside, first mozzle 415 of glue through the glue-feeder place drains in the first de-bubble bucket 41, first mozzle 415 can separate protection glue body particle as much as possible, constantly eliminate the bubble that wraps up between the glue particle in the process that glue in the first de-bubble bucket 41 rises under the condition of vacuumizing, when first sensor 416a sends the signal that detects glue, add full glue in the first de-bubble bucket 41, first combination valve 411 that close the glue-feeder place this moment stops to add glue, wait for the solenoid valve 413 of closing vacuum gas port place again behind the certain hour, and open the solenoid valve 412 at compression gas port place and first combination valve 414 at gum outlet place, in the first de-bubble bucket 41, feed pressurized air, to be transported to down gluing mechanism 50 after the extrusion of the glue in it, in the process that glue is forced out, its residual bubble is further removed, and then obtains meeting the protection glue of production requirement; In the first de-bubble bucket 41 glue add full in, open second combination valve 421 at glue-feeder place of the second de-bubble bucket 42 and the solenoid valve 423 at vacuum gas port place, glue after filtering added in the second de-bubble bucket 42 carry out de-bubble, in the process of adding, glue is carried out de-bubble, when the second sensor 426a detects glue, glue in the second de-bubble bucket 42 adds full, second combination valve 421 that close the glue-feeder place this moment, stop in it, to add glue, still, constantly eliminate the bubble in the glue to vacuumizing processing in the second de-bubble bucket 42; In the second de-bubble bucket 42 glue add full in, open the 3rd combination valve 431 at glue-feeder place of the 3rd de-bubble bucket 43 and the solenoid valve 433 at vacuum gas port place, glue after filtering sucked in the 3rd de-bubble bucket 43 carry out de-bubble, in the process of adding glue is carried out de-bubble, gluing mechanism 50 used under meanwhile the glue in the first de-bubble bucket 41 continued to supply with; When first sensor 416b sends signal, glue in the first de-bubble bucket 41 is all exported, the solenoid valve 423 that close the vacuum gas port place of the second de-bubble bucket 42 this moment, and open the solenoid valve 422 at compression gas port place and second combination valve 424 at gum outlet place, in the second de-bubble bucket 42, feed pressurized air, glue in it is extruded and be transported to down gluing mechanism 50 for use, still injecting glue in the 3rd de-bubble bucket 43 this moment, do not have glue and wait to add glue in the first de-bubble bucket 41 next time; When the 3rd sensor 436a sends the signal that detects glue, glue in the 3rd de-bubble bucket 43 adds full, the 3rd combination valve 431 that close the glue-feeder place this moment, stop in it, to add glue, but still to vacuumizing processing in the 3rd de-bubble bucket 43, with the bubble in the continuous elimination glue, gluing mechanism 50 uses under the glue sustainable supply in the second de-bubble bucket 42, restarts the glue after filtering is injected in the first de-bubble bucket 41 and carries out de-bubble; When the second sensor 426b sends signal, glue in the second de-bubble bucket 42 is exported fully, the solenoid valve 433 that close the vacuum gas port place of the 3rd de-bubble bucket 43 this moment, and open the solenoid valve 432 at compression gas port place and the 3rd combination valve 434 at gum outlet place, in the 3rd de-bubble bucket 42, feed pressurized air, with the glue pressure place in it and be transported to down gluing mechanism 50, this moment, the first de-bubble bucket 41 still added glue, and the second de-bubble bucket 42 empties to wait for and adds glue next time; When filling it up with glue once more in the first de-bubble bucket 41, stop in it, to add glue, the glue after will filtering simultaneously injects in the second de-bubble bucket 42 and carries out de-bubble, and the 3rd de-bubble bucket 43 continues to provide glue to following gluing mechanism; When the glue of the 3rd de-bubble bucket 43 all extrudes, open 41 pairs of following gluing mechanisms of the first de-bubble bucket again glue is provided, and the glue behind the controlled filter continues to carry out de-bubble in the injection second de-bubble bucket 42; When adding full glue in the second de-bubble bucket 42 once more, the glue after filtering injected in the 3rd de-bubble bucket 43 carry out de-bubble, control the first de-bubble bucket 41 and continue to provide glue gluing mechanism down; Three de-bubble buckets so recycle; the memory space of protection glue is increased greatly, with the satisfied lasting needs of producing, and the control by the glue time is protected in the interpolation protection glue time and the extrusion of three de-bubble buckets; strengthen the de-bubble effect, make the protection glue after the de-bubble satisfy the needs that Blu-ray Disc is produced.
