[embodiment]
Adopt the mode of coating while stirring can produce a large amount of bubbles when the present invention is based on dip-coating, the coating that makes coating has the space and the mass defect that causes, the job operation of uniform coating can be provided when providing a kind of conductive rollers to be coated with, it is that two containers that can hold coating are set respectively, wherein a container is done to stir and is used, can man-hour contained each component of coating successively be added by proportioning adding, constantly stir simultaneously, on the one hand, each component is fully mixed, on the other hand, can avoid granular material to produce precipitation, cause the inhomogeneous of coating concentration; Another container then is the dip-coating container of conductive rollers, conductive rollers to be coated can be carried out dip-coating processing in this container, between two containers by set communication passage, the coating that is stirred in the stirred vessel can not forfeited in the coating container, because the coating concentration in this container is even and static, can make conductive rollers to be coated when dip-coating processing, obtain uniform coating, thereby realize purpose of the present invention.
The dip coating apparatus that designs according to above-mentioned thinking as shown in Figure 1.Apparatus of the present invention comprise stirred vessel 4, coating container 8 and mobile clamping device 12, described stirred vessel 4 is used to hold conductive rollers and adds the coating that mixes, and in this stirred vessel 4, is provided with a shaft 2, drive rotation by the stirring motor 1 that is attached thereto, be equiped with stirring vane 3 on the shaft 2.Shaft 2 can vertically be arranged at stirred vessel 4 centers, also can obliquely be arranged in the stirred vessel 4, and itself and stirred vessel 4 centers are 15～30 °, so that stirring extent is stronger.Described stirring vane 3 can adopt helical blade, through whole shaft 2, also can two to three screw type blades only be set in shaft 2 lower ends, be convenient to will be sunken to better the particle dispersed with stirring of bottom, make it in solution, evenly to distribute, make the solubility of coating change controlled.
Described coating container 8 is used to hold coating coating, between described stirred vessel 4 and coating container 8, also be provided with a connecting pipe 5, be used for stirred vessel 4 and coating container 8 coating interface channels, coating after stirring, can obtain the uniform coating of concentration thereby make in the coating container 8 through entering this communicating pipe 5 in the coating container 8.
Described mobile clamping device 12 is used for clamping conductive rollers 9, and conductive rollers 9 is vertical placement, conductive rollers to be coated 9 can be clamped and drives it and do upper and lower displacement above coating container 8.Described mobile clamping device 12 comprises mobile cylinder 121 and claw 122, all can control by control gear, claw 122 can be under control gear control with conductive rollers 9 on end clamp or unclamp, itself and cylinder 121 piston rod external parts join, can under the drive of cylinder 121, do moving up and down, do and move up and down thereby drive conductive rollers 9.When cylinder 121 piston rods stretch out, can drive conductive rollers 9 and stretch into coating container 8 inner chambers, it is immersed in the coating, after dip-coating was finished, coating container 8 was left in the withdrawal of cylinder 121 piston rods.What be worth proposition is, because stirred vessel 8 is tubular cylindrical drum always, has accommodation space greatly, therefore, described claw 122 can be provided with a plurality of, fix by a disc web member, and evenly distributed at this disc web member, join by described disc web member and cylinder 121 piston rod external parts, like this, can once be coated with a plurality of conductive rollers 9, save the coating time greatly, improve production efficiency.
As shown in Figure 1, the present invention moves clamping device 12 upper ends and links to each other with a swing arm 13, being specially cylinder 121 cylinder ends links to each other with the cantilever end of swing arm 13, described swing arm 13 stiff ends place on the frame 14, frame 14 is as the supporting device of mobile clamping device 12 and swing arm 13, this swing arm 13 stiff ends link to each other with motor 15 simultaneously, can be driven by motor 15 rotate, and are used for driving to coating station from workpiece to be processed place extraction conductive rollers 9 to be coated and with it.After dip-coating finishes, drive again and be coated with the conductive rollers 9 that finishes and leave.
For guaranteeing that the coating in the stirred vessel 4 can send in the coating container 8 in time, continuously, on described communicating pipes 5 pipelines, also be provided with a membrane pump 6, coating in the stirred vessel 4 can be extracted out and send in the coating container 8.
Owing to contain partial impurities sometimes in the coating, therefore, the present invention is on communicating pipes 5 pipelines, also be provided with a filtrator 7, it is between membrane pump 6 and coating container 8, enter again in the coating container 8 after the aqueous coating that membrane pump 6 is extracted out in the stirred vessel 4 filter through filter 7 earlier, guaranteed effectively in the coating container 8 solution evenly, inclusion-free, further guaranteed the quality of coating reliably.
As shown in Figure 1, the present invention is also outside described coating container 8, also be provided with an overflow ladle 10, it can be the cylindrical structural member that be surrounded on coating container 8 peripheries of diameter greater than coating container 8, be communicated with stirred vessel 4 by a recirculatory pipe 11, when the coating of membrane pump 6 suction more and when surpassing the capacity that coating container 8 sets, coating can overflow from coating container 8, flow in the overflow ladle 10, again return in stirred vessel 4 by recirculatory pipe 11, like this, can make that the interior liquid level of coating container 8 is constant all the time, always be in full state, thus when having avoided dip-coating because of the not enough error that causes of coating along conductive rollers axis direction thickness.The liquid level position that the present invention also can set at coating container 8 tops is offered a relief port, and this relief port connects recirculatory pipe 11, and excessive solution can be returned in stirred vessel 4 through recirculatory pipe 11 again by this relief port equally.
During work, motor 15 starts, and swing arm 13 is rotated, mobile clamping device 12 places conductive rollers to be processed 9 workpiece places (being generally vertical arrangement), and under control gear control, mobile clamping device 12 opens claw 122, conductive rollers 9 roller cores upper end is clamped, and swing arm 13 is rotated then, is located at coating container 8 tops, at this moment, swing arm 13 stops operating, and cylinder 121 starts, and piston rod stretches out, drive claw 122 and move down, conductive rollers 9 is inserted in the coating container 8.After dip-coating finished, cylinder 121 started, and the piston rod withdrawal drives claw 122 and moves up, make conductive rollers 9 leave coating container 8, at this moment, swing arm 13 starts, and is driven by motor 15 and rotates, when turning to desired location, claw 122 opens, and conductive rollers 9 breaks away from, and it is placed into finished product storing place.
The above embodiment has only expressed the preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
