Abstract
The utility model discloses a novel circuit board printing chassis structure. The novel circuit board printing chassis structure comprises a chassis; a pin hole is formed at the center of the chassis; a flat-topped pin body is inserted into the pin hole; a plurality of positioning pins are evenly distributed at the periphery of the flat-topped pin body; a bottom plate is horizontally arranged at the lower bottom surface of the chassis; a plurality of flitches are stacked sequentially below the bottom plate; the lower bottom surface of the chassis is additionally provided with a layer of sealing plate; the edges of the sealing plate cover the bottoms of the positioning pins; and an adhesive bar is arranged between the sealing plate and the flitches. With the novel circuit board printing chassis structure adopted, the lingering of adhesive residue can be avoided; and production quality problems due to the adhesive residue can be avoided. The novel circuit board printing chassis structure is advantageous in convenient disassembly and assembly, and easiness in cleaning, and can facilitate the improvement of circuit board printing efficiency and the realization of a multi-function property.
Description
Technical field
The utility model relates to printing technology, relates in particular to a kind of Novel circuit board printing chassis structure.
Background technology
Printing technology is all processes of vision, tactile data print reproduction, is to process the technology by the demand batch duplicating fine arts, word, image by pool, photography, word processing and artistic design, editor, color separation, plate-making, printing, seal aftershaping.Printed circuit board develops into double sided board, multi-layer sheet and flex plate from individual layer, and constantly to high accuracy, high density and high reliability future development, continuous reduced volume, Cost reduction, raising performance.Printed circuit board manufacturing technology development trend is to high density, high accuracy, fine pore, thin wire, little spacing, highly reliable, multiple stratification, high-speed transfer, light weight, slim future development on performance.The wire of single sided board wherein only appears at wherein one side, and double sided board is the extension of single sided board, can carry out the circuit of conducting between two-layer by via hole, makes it to form needed network and connects.At present, during the printing process of conducting transmission line plate, usually adopt double faced adhesive tape that locking pin and plastic edge strip are sticked on the seat surface of base, complete locking pin need to be pulled down the time in operation, can be on seat surface the cull of residual lower double faced adhesive tape; When wiring board is carried out to printed on both sides, these culls be easy to be stained with wiring board on the surface of that side of base, thereby cause the problems such as upper tin is bad, when serious, finally can cause scrapping of product; It is important to point out that between each needle body bottom and base plate and be easy to occur the phenomenons such as cull overflows, sealing is poor; And, because floor length is less than chassis length, cause only relying on base plate one deck structure can't guarantee the printing work stability on whole chassis.Therefore, for above aspect, need to make rational improvement.
The utility model content
The purpose of this utility model is to provide a kind of sealing and stability that strengthens needle body bottom and base plate, can avoid leaving over cull, easy accessibility, be convenient to clean, be conducive to improve the Novel circuit board printing chassis structure of wiring board printing efficiency, with many deficiencies of solution prior art.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of Novel circuit board printing chassis structure, comprise chassis, and a pin hole and a flat-top needle body of the inner insertion of this pin hole are offered in described center chassis position, are positioned at this flat-top needle body periphery and are uniformly distributed some pilot pins;
Be positioned at chassis bottom surface level and lay a base plate, simultaneously, described floor below sets gradually some pasting boards from top to bottom, is positioned at the chassis bottom surface and sets up one deck sealing plate and covering pilot pin bottom, this sealing plate edge, between sealing plate and pasting board, is provided with adhesive tape.
Correspondingly, the distance between each pilot pin and flat-top needle body is 11mm, and each pilot pin top is with an apex, and each pilot pin and flat-top needle body bottom surface are closely attached on plate upper surface.
The beneficial effect of Novel circuit board printing chassis structure described in the utility model is:
(1) without using double faced adhesive tape locking pin can be fixed on base, can avoid leaving over cull in susceptor surface, can avoid the product quality problems that may cause due to cull;
(2) by the structures such as base plate and pilot pin are set, there is easy accessibility, be convenient to clean, be conducive to improve the advantages such as wiring board printing efficiency;
(3) by setting up one deck sealing plate with one deck adhesive tape between base plate and chassis bottom surface, be conducive to strengthen sealing and the stability of needle body bottom and base plate, can avoid occurring the phenomenons such as cull overflows.
