Description
Technical field
The present invention relates to wafer polishing equipment in optical element surface or microelectronics, especially precise polished large-sized annular polishing machine is carried out in the surface of large scale optical glass components and parts, the device that carries out off-load transfer for the calibration disc that auxiliary heavy caliber glass pieces is carried out surface accurate polishing on large-scale glass polishing machine especially.
Background technology
Annular polishing machine is current unique heavy caliber, globalize planar optical elements process technology almost in the world, it is that polished workpiece is rotated with respect to polishing lacquer disk(-sc) under the existence of certain pressure and polishing fluid, by the mechanical grinding effect of abrasive particle and the corrosiveness of chemical oxidizing agent, completes smooth finish surface is removed and obtained to the material of surface of the work.Compared with other technology, this technology can realize part and the leveling of large aperture workpiece simultaneously, can eliminate height point and the waveform of surface of the work, eliminates high-frequency defects, and suface processing quality can reach the degree of ultra-smooth; Complanation speed is fast, and machining accuracy is high, applied range, and production cost is low, is applicable to industrial large-scale promotion.Glass polishing machine is the main carriers of this technology.Along with the develop rapidly of modern science and technology, clear aperture and the requirement on machining accuracy of optical element are more and more higher, therefore glass polishing machine also to maximizing, the future development of automation, mesa diameter develops into current 2.4m gradually by original 1m, 1.2m, even 4m is with first-class for 2.8m, and mechanization, automaticity are more and more higher.In general, glass polishing machine mainly comprises a marble polishing dish that is driven rotation by motor, and the upper surface of this polishing disk is poured into a mould the uniform polishing lacquer disk(-sc) of one deck, regulates in addition the calibration disc of polishing lacquer disk(-sc) face shape on polishing lacquer disk(-sc).When glass polishing machine is started working, first an auxiliary polishing workpiece ring for workpiece is placed on to polishing disk, then workpiece to be processed is lain in this workpiece ring, workpiece can only move in workpiece ring like this, be convenient to control in real time and operation, start simultaneously motor drive polishing disk with certain speed around central rotation, simultaneously on polishing lacquer disk(-sc), spray a certain amount of polishing fluid, in polishing fluid, contain the polishing powder particle of particular particle size, size, shape.When polishing disk rotates with certain speed, workpiece does random movement or rotation on polishing lacquer disk(-sc) simultaneously, and produce rubbing action with the polishing powder particle on polishing lacquer disk(-sc), thereby the contact-making surface of workpiece and polishing lacquer disk(-sc) is carried out to material removal to obtain smooth surface.
At present, ring is thrown processing also in relatively relying on the state of artificial experience, and wherein the effect of calibration disc is most important.In general, the surface figure accuracy of processing work depends primarily on the surface figure accuracy of polishing pitch lacquer disk(-sc), and the surface figure accuracy of polishing pitch lacquer disk(-sc) depends on the real time calibration effect of calibration disc.Because polishing pitch has certain elasticity and toughness, easily form good plane, in reality processing, can utilize acting on polishing pitch of calibration disc that weight is larger, rely on the huge weight of calibration disc and move radially polishing pitch dish is carried out to the surface shape value that real-time correction needs to form us.Therefore in polishing process, workman needs often according to the workpiece surface shape value of Real-Time Monitoring, calibration disc is carried out feeding radially and shifted out, or pressurization decompression operation is to obtain required workpiece surface shape value.In addition, polishing lacquer disk(-sc) is used after a period of time continuously, can there is aging phenomenon in surface, the bonding streng of polishing powder particle is reduced, need to again to polishing lacquer disk(-sc), carry out finishing process to improve its polishing ability, therefore need calibration disc, workpiece and workpiece ring temporarily to move to polishing lacquer disk(-sc) is carried out suitable fluting and repaiies dish work.From above two aspects, can find out, no matter be moving radially or the finishing process of polishing pitch lacquer disk(-sc) of calibration disc, all to load calibration disc, off-load and movement, after complete operation, then the objects such as calibration disc are reapposed and on glass polishing machine, carry out next round polishing.At present, because the calibration disc size of large-scale glass polishing machine is larger, full-size reaches nearly 2m, and weight reaches several tons, and smooth surface, holds nowhere, and therefore workman carries very inconveniently, and labour intensity is larger, is very easy to cause workman injured.In addition, in view of the requirement to workpiece fineness at present, the device of calibration disc off-load transfer must cleanly transport with being convenient to, and avoids artificial participation as far as possible, realizes as far as possible mechanized operation.Current glass polishing machine calibration disc off-load shifting apparatus belongs to the go-cart of miniaturization mostly, less for the device of heavy caliber calibration disc off-load transfer; And this class go-cart needs the lubricant methods such as machine oil mostly, the pollutants such as meeting introducing grease more or less, be unfavorable for the surface smoothness index of workpiece, and when calibration disc coils on again, all need workman promote just to complete calibration disc again on dish, this also can introduce unnecessary introduced contaminants.
Off-load shifting apparatus of the present invention adopts mechanical type Material Testing Machine loading structure, by lever principle, pulling force is increased to original decades of times, and pulling force is adjustable, both can realize original position unloading and load operation, can realize again the light transfer of calibration disc, substantially realize the mechanized operation of large-scale glass polishing machine calibration disc off-load transfer, replace original artificial mode, alleviated staff's labour intensity; In addition, this device adopts pulling force regulating spring that power is provided, and does not need lubricated wet goods measure, therefore can not introduce exogenous impurity, has realized the pollution-free carrying of workpiece and workpiece ring.In addition, adopt this device as long as a few minutes can complete off-load and the transfer operation of calibration disc, greatly improved operating efficiency.This apparatus structure is simple, easy to operate, reliable and stable, and precision is higher, has not only greatly improved the security in calibration disc off-load transfer process, and has avoided the introducing of introduced contaminants and surface of the work is caused to damage.
