Describe the embodiment of compression mold device of the present invention in detail below in conjunction with Figure 10.
The cover half device comprises: adsorption hole 2, vacuum pipe 4, centralized positioning axle 3, transparency silica glass 12, briquetting 22, base 23, fixed mechanism 24, jackscrew 26 and latch mechanism 25.The dynamic model device comprises: locating shaft core 6, vacuum pipe 7, guide rod 8, screw rod 10, be with 17 synchronously, screw rod 18, vacuum pipe 13, Constant-temp. pipeline 20 and control device 15,19.
The molded BD blue light substrate 1 of first information layer, after crossing the glue that also not have curing that one deck can be used for forming second Information Level hole line, spin coating is placed on the adsorption hole 2 of cover half, adsorption hole 2 is the holes that are evenly distributed on the quartz glass 12, come the sorption disc by negative pressure of vacuum, wherein vacuum pipe 4 is used for providing negative pressure of vacuum to adsorption hole 2.When regulating cover half device levelness, can unclamp fixed screw 24, adjusting jackscrew 26 is adjusted levelness, locks again after adjustment is finished to get final product.
The center pit that the locating shaft core 6 of dynamic model device penetrates stamper mould stamper 5 positions, and stamper 5 is adsorbed on the locating shaft core 6 by vaccum suction pipe 7.Whole dynamic model device moves downward along guide rod 8 under drive unit drives, and wherein drive unit is a driving source with servomotor 9 preferably, by screw rod 10 transmissions.Stop to descend when the dynamic model device drops to the position of setting, the chamber wall 11 of dynamic model device forms a seal chamber with the briquetting 22 of cover half device, transparency silica glass 12 and base 23, vacuumizes by vacuum pipe 13, finally forms a vacuum chamber 14.Wherein, briquetting is used for pressing quartz glass; Base is used for carrying quartz glass and briquetting.The locating shaft of cover half device, briquetting, quartz glass, base are assembled into an overall fixed on fixed mechanism, and by fixed mechanism the cover half device are fixed on the equipment substrate 27.
Wherein, whether the dynamic model device down to the position of setting, can by control device preferably clock gauge 15 test the position of decline and the deviation of desired location, and can adjust the position that moves up and down of dynamic model device according to deviation.After forming vacuum cavity, the beginning fine motion under drive unit drives of dynamic model device is downward, and wherein drive unit is a driving source with servomotor 16 preferably, by synchronous band transmission 17 and screw rod 18 transmissions.In this process, drive stamper 5 and centralized positioning axle core 6 together down, when moving downward certain distance, the centralized positioning axle 3 of the locating shaft 6 contact cover half devices of dynamic model device, because locating shaft 3 is compressible formula, when the dynamic model device continued to move downward, its locating shaft 6 was depressed locating shaft 3, penetrates the disc center simultaneously.At this moment, all with centralized positioning axle 6 location, because centralized positioning axle 6 is high concentricity part, therefore, being positioned the stamper of this part and the concentricity of disc can be guaranteed for stamper and disc.
In this process, the information of stamper 5 is pressed on the glue layer of BD blue light substrate 1, and whether the degree of depth of pressing this moment reaches desired location, and availability control unit preferably clock gauge 19 is measured.When the dynamic model device is worked up and down,, regulate the distance that the dynamic model device moves up and down by regulating the revolution of servomotor.After the pressing, the UV lamp 21 of opening installation under substrate 27, UV lamp 21 is fixing by UV holder 28, and provides cooling air by cooling device 29, to reduce the temperature of UV lamp.See through 12 pairs of BD blue light disks of transparency silica glass glue and be cured, inflate by 13 pairs of cavitys of vacuum pipe after finishing, the BD blue light disk after the taking-up pressing.
In the overall process that press moulding mechanism starts, thermostat and cooling device 29 are all in running; Wherein, the preferred waterway pipe 20 of thermostat provides thermostatted water to keep the constant temperature of press moulding mechanism by thermostat.
The above only is preferred embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
