Deng）Carry out the light source mechanism of surface exposure.
Background technology
With the development of electronic technology, wiring board（PCB/FPC etc.）Application it is more and more extensive, for its processing and manufacturing
Technical requirements more and more higher.It is one of important procedure in circuit board manufacturing process that surface ink exposure is carried out to wiring board, its
Determine the final quality of wiring board.The light source mechanism of conventional exposure machine is essentially all as light source, Er Qiedou using mercury lamp
It is that by the way of single light source, then light source passes through one piece again by certain governor motion adjustment light, such as fly's-eye lens
The plane light microscopic of middle transition, light is reflected to a speculum by the latter road of plane light microscopic and is irradiated to exposure position, another
Road is then irradiated to another speculum through plane light microscopic and reflexes to exposure position, this mode as a kind of traditional habit always all
Do not changed.However, this traditional light source set-up mode haves the shortcomings that larger, first, the energy of single light source in itself is just
It is not very sufficient, by the transition of plane light microscopic, energy can decay, and needs longer distance, energy by reflection and refraction again
It can decay again, so that the light energy for eventually arriving at exposure position has obvious reduction, so as to cause the efficiency of exposure
Relatively low, completing single exposure needs longer time, as completing the time for exposure of a frame more than 15 seconds；Secondly, use
Mercury lamp not only results in serious pollution problem, and mercury lamp extremely power consumption in itself, and the separate unit machine power consumption of one week is at 1,000 degree
More than, use cost is very high；3rd, because two-sided illumination needs to send from a light source, and the meeting pair after plane light microscopic
The round of light causes to change, therefore traditional approach will set considerably complicated adjustment mechanism, to enter line position to light source
Put adjustment and can be only achieved more accurate irradiation position, so as to cause mounting structure more complicated, installation cost is high, regulation operation
It is complicated.
Utility model content

Line light source mechanism, includes two reflective mirrors, i.e. the first reflective mirror and the second reflective mirror, and two reflective mirrors are respectively in the two of exposure table top
Side is simultaneously tilted towards exposure table top setting, it is characterised in that：Light source uses LED/light source, includes two groups of LED/light sources, i.e., first
LED/light source module and the second LED/light source module, wherein the first LED/light source module is towards the first reflective mirror, the light that it sends is straight
Connect and be irradiated to the first reflective mirror and be irradiated to exposure table top in directional light after the first mirror reflection；Second LED/light source module
Towards the second reflective mirror, its light sent shines directly into the second reflective mirror and shone after the second mirror reflection in directional light
It is mapped to exposure table top.Both can double light sources work simultaneously, can also single light source work.
Further, the first LED/light source module and the second LED/light source module are planar array LED/light source, both
With identical structure.
Further, the light source mechanism is installed in the frame of exposure machine, and the first of adjustable angle is provided with frame

Further, the first light source fixed plate and secondary light source fixed plate are connected as one, and it generally one can be with
The angle support of adjustment angle, the first light source fixed plate and secondary light source fixed plate are respectively the both sides daughter board of the angle support；The angle
Support is installed in frame by mobilizable fixing device.
Preferably, it is equipped with the marginal position of first reflective mirror and second reflective mirror for limiting light source photograph
The light position-limit mechanism of scope is penetrated, light regulating direction of illumination can be easily helped.
The utility model is by using two groups of LED/light sources, and it is straight that two groups of light sources are arranged at the position nearer apart from reflective mirror
Irradiation reflective mirror is connect, the plane light microscopic of middle transition is eliminated, so as to which intensity of illumination is improved more than twice, and effect is exposed
Rate can then improve more than 3 times, and the time for exposure for such as completing same frame wiring board is only 5 seconds, and power consumption is only 200 within one week
Many degree, reduce more than 75%；In addition, the mounting structure of whole equipment is comparatively simple, installation cost reduction by 50% or so, for shining
The regulation of firing angle degree has been also convenient for a lot.
