Now, as described in the radome sheet material 10 of the multiple dowel hole of formation to be cut by continuous punching by decompressor with the predetermined pattern corresponding to the various shapes of tellite and bending and manufacture radome.
Preferably, carry out punch process to radome sheet material 10, distinguish the part of screen 12 and non-print shield layer, such as, screen forms upper plate, and the metallic plate of non-print shield layer can form side plate, can be made up of the hull shape opened above.
embodiment 2
This embodiment also comprises and utilizes bat printing and the operation be cured radome sheet material and aqueous coating at this, but this additional process also can apply in a supplementary manner in described embodiment 1.Be described in detail referring to Fig. 3 and Fig. 4.
1st step (S310) according to the present invention is in order under the metallic plate 11 with conductivity being rolled into state that roll prepares, utilizes the operation of conveyer belt 121 described metallic plate 11 without interruption.
Before described 1st step, the present invention also can comprise the described surface at metallic plate 11 is utilized phosphate, chromate, titanium, nitrite, pyrrole, and molybdate or the more than one medicine be combined to form wherein selected carry out the operation of washing.
Described washing procedure for metallic plate 11 is fed into dislodger, Supersonic wave trough, flushed channel, steam groove in turn, and to the operation that described metallic plate 11 washs.
Now, other foreign matters formed on the surface of metallic plate 11 are carried out emulsification and 1 washing by medicine by described dislodger, and, give vibrations removing foreign matter by ultrasonic waves, relevant wash conditions, for carry out under 40 ~ 50 ° 25 ~ 35 seconds, carries out 10 ~ 20 seconds under Supersonic wave trough condition.
Described Supersonic wave trough, while being utilized by the metallic plate 11 through dislodger medicine to carry out 2 washings, utilize ultrasonic waves apply vibrations and remove foreign matter, relevant wash conditions is under 40 ~ 50 ° 25 ~ 35 seconds, and Supersonic wave trough condition is for carrying out 10 ~ 20 seconds.
Described flushed channel is washed with water by the metallic plate 11 through dislodger, and relevant wash conditions is for carrying out 25 ~ 30 seconds.
Described steam groove, through the metallic plate 11 of flushed channel by the condensing trickling of the medicine of heating steam, finally play the functions/drying of developing result and medicine, related conditions for carry out 25 ~ 35 seconds under 47 ~ 57 °.
And, 2nd step (S320) is the Working position metallic plate 11 of supply being fed into pad printer 122, further, use the operation of the aqueous coating bat printing screen 12 of wave shield function with the predetermined pattern corresponding to the various shapes of tellite P.C.B on the surface of the metallic plate 11 dropped into.
And, the bat printing operation of described 2nd step (S320) is the outstanding aqueous coating of printing insulation characterisitic and shield effectiveness, therefore, after described metallic plate 11 pairs of electric waves carry out 1 shielding, carry out 2 shieldings at described screen 12 pairs of electric waves, and the induction obstacle of the signals such as the noise because occurring in electronics, communication equipment and electromagnetic induction can be prevented.
Described screen 12, as as described in embodiment 1 identical, the acrylamide series be made up of 1 liquid type (aqueous coating) or 2 liquid types (aqueous coating+curing agent), urethane series, epoxy series, fluororesin series or the more than one bat printing ink be combined to form wherein selected.
Described screen 12, carry out on the surface of metallic plate 11 1 time or print for several times and carry out, its thickness is 0.5 ~ 200 μm, and elongation is more than 50%, and confficient of static friction is less than 0.5 μ.
After described pad printer 122 is transferred to the elastomeric transfer plates such as glue, silica gel, donkey-hide gelatin for being rule by ink, be printed in the mode of object, because printing has elasticity, thus, can have plane, curved surface, concave surface, convex surface the object of small size print.
Therefore, the printing surface of screen 12 is soft, also easily prints at curved body, and the selection of ink is also free, and ink layer is not easy to be stripped, and is suitable for a large amount of productions of automation.
3rd step (S330) is dropped into drying machine 123 by the metallic plate 11 of coating screen 12, carries out dry operation to described screen 12.
Further, the drying process of described 3rd step (S330) is make to print the screen 12 that aqueous ink formed solidify and be not stripped.
Further, described drying machine 123 selects some uses in hot blast or UV curing mode, and its temperature carries out 20 ~ 30 minutes under 120 ° ~ 150 °.
Further, the 4th step (S340), for after screen 12 drying, applies clear coat liquid on the surface of described metallic plate such as screen 12 grade 11 by spraying machine 124 and forms the operation of overlay 13.
And; the coating liquid working procedure of coating of described 4th step (S340) is; in the process that the metallic plate 11 being formed with screen 12 is carried by conveyer belt 121; by the surface automatic spraying and applying liquid of spraying machine 124 to described metallic plate such as screen 12 grade 11, and the shape forming thin diaphragm forms overlay 13.
Described coating liquid comprise select in aqueous transparent polyurethane, epoxy, rubber polymer, silicon some more than.
Described overlay 13 is by spraying machine coating liquid coating, and its thickness is 1 ~ 100 μm, and elongation is more than 50%.
5th step (S350) is for dropping into the metallic plate 11 being formed with overlay 13 to ultrasonic waves drying machine 125 and described overlay 13 being carried out to the operation of ultrasonic waves drying.
The ultrasonic waves drying process of described 5th step (S350), the overlay 13 formed to apply aqueous coating liquid is not stripped and is cured.
Now, after the operation of described 5th step (S350) terminates, described radome sheet material 10 is rolled into roll and loads.
Further, also comprise the 6th step (S360), before described 2nd step, or after described 5th step, the part being printed with screen 12 to be cut by decompressor continuous punching and bending, be fabricated to radome.
Described 6th step (S360), before formation screen 12, when namely performing before the 2nd step, after metallic plate 11 is processed as radome, multiple radomes of processing are fed into pad printer 123 and on radome, form screen 12, as to be formed after screen 12 namely carry out after the 5th step time, peripheral part punching being formed at the screen 12 of metallic plate 11 is cut and bending after manufacture radome, about operation is optionally carried out.
Now, described 6th step (S360) is make it have to be applicable to the adjacent shape of tellite configuration and the operation of structure by radome sheet material 10 punch process, metallic plate 11 to decompressor 126 supply is rushed continuously to be cut and bends and be fabricated to radome, such as, the part forming screen 12 forms the upper plate of radome, the part not forming the metallic plate 11 of screen 12 forms the side plate of radome, with the hull shape making described radome be manufactured to bottom surface opened.
Thus make the printing surface of screen 12 soft and be also easily printed at curved body, also freely, ink layer is also not easy to be stripped in the selection of ink, and applicable automation is produced in a large number.
