Description
Technical field
The utility model is related to a kind of processing unit (plant) of pcb board production.
Background technology
Carrying out when pcb board is produced, it is necessary to one layer of uniform green oil film of surface coating of PCB substrate, apply this
Plant green oil film is generally carried out using screen printer.The shortcoming that screen printer of the prior art is present is exactly the uneven thickness of coating
Even, thickness is also not easily controlled.
Utility model content
In order to solve problem present in background technology, the utility model provides a kind of silk-screen for pcb board production
Machine, the screen printer can control the thickness of coating and keep coating green oil film thickness uniform.
To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of screen printer for pcb board production, including transmission base, it is characterised in that be arranged side by side in transmission base
There are multiple live-rollers, transmission base top is provided with silk-screen shower nozzle, and silk-screen shower nozzle includes outer shower nozzle, and the center of outer shower nozzle is provided with
The bottom place plane of outer shower nozzle is stretched out in interior shower nozzle, the bottom of interior shower nozzle, and the bottom of interior shower nozzle is provided with thin nozzle, and thin nozzle is used
In green oil film is sprayed, the both sides lower sidewall of outer shower nozzle is provided with rotation ball, and the sidewall bottom of outer shower nozzle is provided with painting wiping, applies
The outer wall of ball is close to rotate in the bottom of wiping, and the space between interior shower nozzle and outer shower nozzle is air draft passage.
Air draft passage is connected with extractor fan.
The extractor fan is air exhauster.
The number of live-roller is 3.
Driving front roller and rear live-roller are respectively arranged with before and after the transmission base.
The beneficial effects of the utility model are：The screen printer can control the thickness of coating and keep applying green oil thickness
Degree is uniform.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the structural representation of screen printer described in the utility model；
Specific embodiment
Explanation and specific embodiment are further described to the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in figure 1, a kind of screen printer for pcb board production, including transmission base 1, it is arranged side by side in transmission base 1
There are multiple live-rollers 2, in the present embodiment, the number of live-roller 2 is 3, and driving front is respectively arranged with before and after transmission base 1
Roller 4 and rear live-roller 3, the top of transmission base 1 are provided with silk-screen shower nozzle, and silk-screen shower nozzle includes outer shower nozzle 6, the center of outer shower nozzle 6
Interior shower nozzle 5 is provided with, the bottom place plane of outer shower nozzle 6 is stretched out in the bottom of interior shower nozzle 5, and the bottom of interior shower nozzle 5 is provided with thin spray
Mouth, thin nozzle is used to spray green oil film, and the both sides lower sidewall of outer shower nozzle 6 is provided with rotation ball 7, the sidewall bottom of outer shower nozzle 6
Painting wiping 8 is provided with, the outer wall of ball 7 is close to rotate in the bottom for applying wiping 8, and the space between interior shower nozzle 5 and outer shower nozzle 6 is exhausting
Passage 9, air draft passage 9 is connected with extractor fan.Extractor fan is air exhauster.
When carrying out silk-screen, PCB substrate 10 is shelved in transmission base 1, in the rotation of driving front roller 4 and rear live-roller 3
Under drive, PCB substrate is moved horizontally by a lateral other side, and at this time green oil film sprays from interior shower nozzle 5 through thin nozzle, spray
To the surface of PCB substrate 10, due to the swabbing action of air draft passage 9, unnecessary green oil mould is not had and is piled up, and turned
Under the rotation of dynamic ball, green oil film is spread evenly, and the green oil die coating unnecessary on ball 7 that will rotate for applying wiping 8 is scraped, and be also ensure that
The thickness of green oil mould is uniform.
It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, can be to above-mentioned
Implementation method carries out various modifications, change and combination, and thinks that this modification, change and combination are the models in originality thought
Within enclosing.
