Description
Technical field
The present invention relates to electricity pcb board field, specifically a kind of pcb board coating baking all-in-one machine and its control electricity
Road.
Background technique
Known pcb board coating machine mostly includes into plate, coating and baking, wherein in application step, tradition
Pcb board oiling when be mode of operation using roller type oiling, in traditional pcb board during oiling conveys, due to
Bottom surface is contacted with the surface of delivery roller, and oiling is easy to be sticked on idler wheel, causes pcb board oiling uneven, poor product quality,
Yield rate is low etc..Therefore, for the deficiency in traditional pcb board oiling technical problem, meanwhile, part coating in the prior art
Machine is using taper delivery wheel, and the both ends of pcb board can be supported to carry out aerial conveying, and it is defeated to avoid the contamination of pcb board oil surface
Wheel is sent, still, there is cause to rub because of the attachment of each taper delivery wheel surface impurity for the pcb board entered in taper delivery wheel
So that banking motion occurs on taper delivery wheel in pcb board, and then there is pcb board oil surface and scratches in the difference of power
The case where taper delivery wheel, and taper delivery wheel can not adapt to the conveying of the pcb board of various sizes, when need to convey
When pcb board is the miniature pcb board of laboratory or small household appliances, taper delivery wheel can not then be applicable in the requirement of this kind of pcb board of conveying；
In baking procedure, the baking box of pcb board coating machine, including cabinet, is set to the intracorporal blower of case and adds at present
Heat pipe, the hot-blast outlet being opened on the cabinet and return air inlet etc., but all there is heat waste, do not make full use of
Situation.

(3) a kind of heretofore described pcb board coating baking all-in-one machine and its control circuit, pcb board and fagging machine
It is contacted between structure for line, and in pcb board during horizontal movement in fagging mechanism, fagging mechanism can also be to coated
The effect of pcb board left and right ends applied force, so that pcb board preferably carries out horizontal movement, it is opposite to be conveyed with traditional taper
For wheel conveying pcb board, the design of the invention so that coated pcb board be unlikely in transmit process inclination or because
Pcb board area is too small, and causes to scratch between the pcb board surface for coating ink and fagging mechanism.
(4) a kind of heretofore described pcb board coating baking all-in-one machine and its control circuit, the push of delivery device
The design of plate is allowed the invention to by pcb board while carrying out in fagging mechanism, and delivery device will not touch pcb board
The upper surface and lower end surface of upper coated ink, avoid coated ink from being pushed mechanism and are scratched.
(5) a kind of heretofore described pcb board coating baking all-in-one machine and its control circuit, apparatus for baking can be with
Fagging mechanism it is automatic gathering and stretching, extension and the design of synchronous gathering and stretching, extension, enable the baking area of apparatus for baking according to
The area of pcb board is automatically adjusted, so that will not be excessive and pcb board area is too small because of baking area, to cause
The waste of heat can adequately economize on resources.
(6) a kind of heretofore described pcb board coating baking all-in-one machine and its control circuit, delivery device front side are surveyed
The design of distance meter plate is allowed the invention to according to the pcb board width measured on rangefinder plate come in adjust automatically fagging mechanism
The space size in portion enables position of the pcb board in fagging mechanism more accurate.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of heretofore described pcb board coating baking all-in-one machine and its control
Circuit can be realized and prevent scratching transport to the aerial of arbitrary size pcb board, while can adequately utilize heat, reduce energy
Source loss.
