Abstract
The invention discloses a circuit board printing chassis with a double-row fixed pin structure. The circuit board printing chassis comprises a chassis, wherein the central position of the chassis is provided with a pin hole, a flat-top pin body is inserted into the pin hole, and a plurality of locating pins are uniformly distributed at the periphery of the flat-top pin body; a bottom plate is horizontally paved at the bottom surface of the chassis; flitches are arranged below the bottom plate; a sealing clapboard is additionally arranged between the bottom surface of the chassis and the bottom plate; a circle of sealing ring is arranged at a gap between the outer edge of the sealing clapboard and the lower part of the chassis and is fastened at the bottom surface of the chassis. The circuit board printing chassis has the beneficial effects of capability of avoiding adhesive residues left on the surface of a base and solving the production quality problem possibly caused by the adhesive residues, has the advantages of convenience in disassembly and assembly, convenience in cleaning, improved circuit board printing efficiency, and the like, and is conductive to realizing the multi-functional purpose of the printing chassis.
Description
Technical field
The present invention relates to printing technology, relate in particular to a kind of double locking pin structural circuit plate printing chassis.
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, in operation, complete locking pin need to be pulled down the time, 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, be easy to occur the phenomenons such as cull overflows between base plate and chassis, sealing is poor.Therefore, for above aspect, need to make rational improvement.
Summary of the invention
The purpose of this invention is to provide and a kind ofly strengthen sealing and stability between needle body bottom, base plate, pasting board, can avoid leaving over cull, easy accessibility, be convenient to the double locking pin structural circuit plate printing chassis of cleaning, being conducive to improve the wiring board printing efficiency, to solve many deficiencies of prior art.
Purpose of the present invention is carried out specific implementation by the following technical programs:
A kind of double locking pin structural circuit plate printing chassis, comprise chassis, a pin hole and flat-top needle body of the inner insertion of this pin hole are offered in described center chassis position, be positioned at this flat-top needle body periphery and be uniformly distributed some pilot pins, be positioned at chassis bottom surface level and lay a base plate, described floor below arranges pasting board, between chassis bottom surface and base plate, sets up a seal diaphragm.
Correspondingly, be positioned at that gap, seal diaphragm outer edge and chassis below arranges a circle sealing ring and this sealing ring is anchored on the chassis bottom surface; Each pilot pin top, with an apex, is set up one and is reinforced the flat-top pin on the chassis between each pilot pin and flat-top needle body.
The beneficial effect on double locking pin structural circuit plate printing of the present invention chassis is:
⑴ 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;
⑵ reinforce the structures such as pin by base plate and pilot pin, flat-top are set, and has easy accessibility, is convenient to clean, is conducive to improve the advantage such as wiring board printing efficiency;
⑶ by below pilot pin and between base plate, setting up the integrated sealing plate, simultaneously, set up a circle sealing ring between this sealing plate outer edge and chassis bottom surface, be conducive to strengthen sealing and the stability between needle body bottom, base plate, pasting board.
