Abstract
The utility model discloses a double-row fixation pin structure type circuit board printing chassis. The double-row fixation pin structure type circuit board printing chassis comprises a chassis. A pinhole is formed in the central position of the chassis, a flat pin is inserted into the pinhole, a plurality of positioning pins are distributed uniformly on the periphery of the flat pin; a baseboard is horizontally laid on the lower bottom surface of the chassis, a pasting board is arranged under the baseboard, and a sealing partition board is added and arranged between the lower bottom surface of the chassis and the baseboard. A sealing ring is arranged at the outer edge of the sealing partition board and at the gap position under the chassis, and the sealing ring is fastened onto the lower bottom surface of the chassis. The double-row fixation pin structure type circuit board printing chassis has the following advantages that defective gum can be avoided from being left on the surface of the base, the production quality problem that may be caused by the defective gum can be avoided; advantages, such as convenient assembly and disassembly, easy cleaning, facilitated improvement of circuit board printing efficiency, etc., can be realized; and the realization of the multifunctionality purpose of the printing chassis can be facilitated.
Description
Technical field
The utility model relates to printing technology, relates 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, 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, 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.
The utility model content
The purpose of this utility model is to provide and a kind ofly strengthens sealing and stability between needle body bottom, base plate, pasting board, can avoid leaving over cull, easy accessibility, is 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.
The purpose of this utility model 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 a 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, sets up a seal diaphragm between chassis bottom surface and base plate.
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 described in the utility model chassis 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) reinforce the structures such as pin by base plate and pilot pin, flat-top are set, there is easy accessibility, be convenient to clean, be conducive to improve the advantage such as wiring board printing efficiency;
(3) by setting up the integrated sealing plate below pilot pin and between base 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.
The accompanying drawing explanation
Below according to drawings and embodiments the utility model is described in further detail.
Fig. 1 is the structure chart on the described double locking pin structural circuit plate printing of the utility model embodiment chassis.
In figure: 1, chassis; 2, pilot pin; 3, flat-top needle body; 4, base plate; 5, apex; 6, pin hole; 7, pasting board; 8, seal diaphragm; 9, sealing ring; 10, reinforce the flat-top pin.
Embodiment
As shown in Figure 1, the described double locking pin structural circuit plate printing of the utility model embodiment chassis, comprise chassis 1, described chassis 1 center position is offered a pin hole 6 and a flat-top needle body 3 of this pin hole 6 inner insertions vertically downward, be positioned at these flat-top needle body 3 peripheries and be uniformly distributed some pilot pins 2 and these pilot pins 2 point circular array formula distribution centered by flat-top needle body 3, the apex 5 that each pilot pin 2 top is triangular structure with a cross section;
Be positioned at chassis 1 a bottom surface level base plate 4 of laying and each pilot pin 2 and be closely attached on base plate 4 upper surfaces with flat-top needle body 3 bottom surfaces, the distance between each pilot pin 2 and flat-top needle body 3 is 15mm;
Simultaneously, described base plate 4 belows arrange pasting board 7, set up a seal diaphragm 8 between chassis 1 bottom surface and base plate 4, be positioned at seal diaphragm 8 outer edges and one circle sealing ring 9 is set 1 gap, below, chassis and this sealing ring 9 is anchored on chassis 1 bottom surface, set up one on the chassis 1 between each pilot pin 2 and flat-top needle body 3 and reinforce flat-top pin 10.
Claims (4)
