[specific embodiment]
Below the structure of the main antifouling film apparatus for coating of accompanying drawings (hereinafter to be referred as apparatus for coating).
As shown in Figure 2, apparatus for coating comprises the applicator roll 220 of material conveying platform 210, coating anti-pollution material, first stepper motor 240 that adsorb the adsorbent equipment 230 of base material to be coated, the described adsorbent equipment of control that links to each other with described adsorbent equipment 230 rises or descends, the second stepper motor (not shown) that rotates by control adsorbent equipment horizontal movement of synchromesh gear band and applicator roll, is arranged on the drying device 250 and the discharging platform 260 of base material behind drying coated between described applicator roll and the described discharging platform.
The aluminum alloy materials that material conveying platform 210 and discharging platform 260 adopts polishing is as table top, and any surface finish, degree of roughness are low, can not produce pure flat substrate surface to scratch, and cleaning easily can not polluted the base material lower surface that will film yet simultaneously.
Preferably, apparatus for coating also comprises liquid bath 222 and the smoothing roller 224 that is used to hold anti-fouling material, smoothing roller 224 is driven by applicator roll 220 as driven pulley, and second stepper motor drives applicator roll 220 by the synchromesh gear band and rotates the sticking anti-fouling material of getting from liquid bath 222.Applicator roll 220 utilizes the frictional force drives smoothing roller 224 between itself and the smoothing roller 224 to rotate, and can make the sticking anti-fouling materials of getting in applicator roll 220 surfaces more even, thereby make base material obtain to be coated with more uniformly effect.
Applicator roll 220 and smoothing roller 224 have the metallic elastic roller of rubber layer or resin bed for outer wrap, and the shore hardness scope of rubber layer or resin bed is the 40-90 degree.Adopt the elastomeric material covering surfaces can guarantee that base material is had sufficient buffer protection, avoid because rigid mechanical mechanism causes damage to ultra-thin base material.
Adsorbent equipment 230 is used to adsorb base material to be coated, comprises vacuum generator 232 and sucker 234, base material that described sucker 234 absorption of vacuum generator 232 controls are to be coated or the base material after the release coating.Link to each other by turn-screw 270 between first stepper motor 240 and the adsorbent equipment 230; the revolution that drives first stepper motor 240 by pulse electrical signal can accurately be controlled the height that adsorbent equipment 230 descends by turn-screw 270; thereby the pressure between control base material and applicator roll 220 roll surfaces, avoid base material in coating process, produce the undulatory coating vestige of water or with the generation of situations such as applicator roll 220 collisions or base material crushing.
Second stepper motor is controlled by programmable logic controller (PLC) (PLC), by the horizontal movement of synchromesh gear band driven in synchronism adsorbent equipment 230 and the rotation of applicator roll 220, make the horizontal movement speed of adsorbent equipment 230 consistent, thereby guarantee that with proper speed the each several part coating of base material in coating process evenly and not can leave undulatory vestige with the rotational line speed of applicator roll 220.
Drying device 250 is the hair dryer structure, and is preferred, comprises heater 252 and hair-dryer 254.Adopt base material after 250 pairs of coatings of drying device to carry out predryingly directly sending by discharging platform 260 again, wait for that drying time is short, the operating efficiency of whole workbench is improved.
PLC controls second stepper motor and is coated with by rate curve shown in Figure 3, use the fast speed feeding in a stage, advance into the b stage of deceleration in the applying area of base material arrival applicator roll 220, the coating of glass substrate head is at the uniform velocity carried out with the speed of minimum in the back of slowing down, i.e. c stage, treat that the head coating finishes after-acceleration and enter the d stage, at the uniform velocity carry out the mid portion coating of base material, enter the e stage when soon being coated with, quickening the coating stage, the last f stage is the discharging discharging stage.The speed of above-mentioned each stage base material to be coated is controlled at: a stage speed: 200-250mm/s; C stage speed: 60-75mm/s; D stage speed: 75-120mm/s, preferred 100mm/s; E stage speed: 120-180mm/s, preferred 170mm/s.According to time in each stage of size Control of base material to guarantee to obtain the evenly antifouling film of coating effect.
When apparatus for coating is worked,, can avoid in coating process, occurring the phenomenon of " head skiving " and " afterbody hangover " by control to base material movement velocity in coating process.Head weakens phenomenon, be that base material contacts with 220 of applicator rolls in the short time that has just begun in the wet coating process to be coated with, metallic elastic roller areal deformation amount is grown out of nothing to arrive to be out of shape again and is stablized, need certain adjustment process, cause the film material of base material head coating less easily, cause head coating rete skiving phenomenon; Afterbody conditions of streaking, the i.e. discontinuous phenomenon that causes film material to assemble of base material in the wet coating process at the base material afterbody.
Adopt the apparatus for coating of said structure can make the antifouling film of ultra-thin pure flat single face that thickness is 0.3-3.0mm; preferred antifouling film is a fluoro-containing macromolecule material; solid content is 0.05-1.0%, can satisfy the antifouling film coating of the single face demand of base materials such as the LCD cover glass that is of a size of the 2.2-24 inch, hand-set lid glass, sight glass, computer monitor cover glass, touch screen protective glass.
By the sucker adsorption substrates and by the distance between step motor control sucker and the applicator roll roll surface, can effectively control the pressure between base material and the applicator roll surface, prevent that base material from producing the undulatory coating vestige of water in coating process, make the antifouling film of single face of coating evenly smooth, and can avoid the generation of situations such as base material and applicator roll collision, crushing, prevent antifouling membrane material dipping, be diffused into the non-coated surface of base material.
Only need manual material loading and blanking, whole transmission and be coated with membrane process and move by procedure auto-control, alleviated operation producers' labour intensity greatly, and above-mentioned coating operates under the atmosphere and just can realize, do not need expensive vacuum coating equipment, the environmental requirement of reduction equipment operation realizes the antifouling rete coating of single face, improve production efficiency, reduced production cost.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
