Description

A kind of circuit board screen printing device
Technical field
The utility model relates to screen printing device, particularly a kind of circuit board screen printing device.
Background technology
Circuit board, is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.Because it is to adopt electron printing to make, therefore be called as printed circuit board (PCB).Before printed circuit board occurs, the interconnection between electronic devices and components is all to rely on electric wire directly to connect realization, and now, printed circuit board (PCB) has occupied the status of empery in electronics industry.According to the circuit number of plies, circuit board is divided into single sided board, dual platen and multi-layer sheet.Common multi-layer sheet is generally 4 laminates or 6 laminates, and complicated multi-layer sheet can reach tens layers.Single sided board is on the most basic circuit board, and part concentrates on wherein one side, and wire concentrates on another side, because single sided board has many strict restrictions in designed lines, so only have early stage circuit just to use this class plate.There is wiring on the two sides of dual platen, but will use the wire on two sides, must between two sides, have suitable circuit to connect, and " bridge " between sort circuit is called guide hole.Guide hole is on circuit board, be full of or the duck eye of coated with metal, it can be connected with the wire on two sides, because the Area Ratio single sided board of dual platen is large one times, dual platen has solved in single sided board because the staggered difficult point of wiring, and it is more suitable for being used in than on the more complicated circuit of single sided board.Multi-layer sheet has been used more single or two-sided wiring plates, with one two-sided do internal layer, two one sides do outer or two two-sidedly make internal layer, two one sides are made outer field printed substrate, by navigation system and adhesive material alternately together and the printed substrate that interconnects by designing requirement of conductive pattern just become four layers, six-layer printed circuit board, also referred to as multilayer printed circuit board.If most motherboard is all the structure of 4 to 8 layers.
As purposes electronic element products the most widely, circuit board has powerful vitality.At present, circuit board is carrying out in the process of silk-screen, conventionally need to be by ink printing in the through hole on circuit board, and traditional method is generally that circuit board is placed on screen printing table, then on circuit board, covers silk screen printing.But in use easily there is the problems such as mesh is not full, mesh hole due to silk screen, thereby cause producing the quality problem such as bubble in the through hole on circuit board, make the circuit board repair rate of serigraphy very high, increased production cost; And circuit board is placed on silk-screen table top, while printing second, easily causes circuit board plate to be bonded on silk-screen table top, fall that oil, efficiency are low, quality is without shortcomings such as guarantees.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the circuit board that a kind of efficiency is high, quality good and repair rate is low screen printing device is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of circuit board screen printing device, it comprises screen printing table, circuit board and web plate, on described screen printing table, be provided with multiple support protrusion, support protrusion middle part is provided with a step surface, described circuit board is placed on the step surface of support protrusion 2, on circuit board, be distributed with multiple consents, described web plate offers the mesh corresponding with circuit board consent, and on web plate, offer the through hole matching with support protrusion, the through hole that web plate is fixed on circuit board top and web plate passes support protrusion.
Described support protrusion quantity is four, and being distributed on screen printing table upper surface symmetrically.
Described support protrusion be shaped as " L " shape.
Described web plate both sides are provided with sealing strip.
Described web plate is aluminium sheet.
Described through hole is " L " shape through hole.
The utlity model has following advantage: circuit board screen printing device of the present utility model, fixing corresponding to the consent on circuit board by the mesh on web plate, ink enters in consent by mesh, make in circuit board consent ink more even, avoid on circuit board ink in consent to produce bubble, improve the quality of product, reduce repair rate, and circuit board is placed on the step surface of support protrusion, circuit board is not contacted with silk-screen table top, while carrying out again second printing, circuit board can not be bonded on silk-screen table top, thereby it to have efficiency high, the advantage that quality is good and repair rate is low.

Fig. 2 is the schematic top plan view of the utility model web plate;
Fig. 3 is the amplification schematic top plan view of the utility model support protrusion;
In figure, 1-screen printing table, 2-support protrusion, 3-through hole, 4-sealing strip, 5-mesh, 6-web plate, 7-circuit board, 8-step surface, 9-consent.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of circuit board screen printing device, it comprises screen printing table 1, circuit board 7 and web plate 6, on described screen printing table 1, be provided with multiple support protrusion 2, the support protrusion 2 of the present embodiment be shaped as " L " shape, quantity is four, and being distributed on screen printing table 1 upper surface symmetrically, as shown in Figure 3, support protrusion 2 middle parts are provided with a step surface 8, described circuit board 7 is placed on the step surface 8 of support protrusion 2, on circuit board 7, be distributed with multiple consents 9, as shown in Figure 2, described web plate 6 offers the mesh 5 corresponding with circuit board 7 consents 9, and on web plate 6, offer the through hole 3 matching with support protrusion 2, through hole 3 is " L " shape through hole, the through hole 3 that web plate 6 is fixed on circuit board 7 tops and web plate 6 passes support protrusion 2, web plate 6 both sides are provided with sealing strip 4, web plate 6 is aluminium sheet.
The course of work of the present utility model is as follows: circuit board 7 is placed on step surface 8, then the web plate corresponding with the consent 9 of circuit board 76 is arranged on the upper surface of circuit board 7, because offer the through hole 3 of " L " shape of matching with support protrusion 2 on web plate 6, web plate is accurately positioned on circuit board 7 upper surfaces, make mesh 5 and the corresponding laminating of consent 9, then circuit board 7 is carried out to silk-screen, in silk-screen printing process, ink enters into by mesh 5 in the consent 9 of circuit board 7, make in the consent 9 of circuit board 7 ink more even, avoid blue glue in the consent 9 on circuit board 7 to produce bubble, improve the quality of product, and support protrusion 2 supports circuit board 7, avoid circuit board 7 to contact with screen printing table 1, while carrying out again the printing of second, circuit board 7 can not be bonded on silk-screen table top.
