Description
Technical field
The present invention relates to a kind of impression method that is coated with, be meant a kind of printing process of on led light source, smearing dirty oil especially.
Background technology
As everyone knows, along with the development of society, led light source is as a kind of new type light source, with its low suppling voltage, and low-power consumption, the long-life, radiationless characteristics are applied in many occasions, and LED display is exactly a kind of concrete application of led light source.LED display cry again electronic display its form by the LED dot matrix, the light on and off by redness or green light pearl come display text, picture, animation, video, content can be changed at any time, the each several part assembly all is the display device of modular construction.Usually form by display module, control system and power-supply system.The dot matrix that display module is made up of the LED lamp constitutes, and is responsible for luminous demonstration; Control system can allow contents such as screen displaying character, picture, video by the light on and off of control respective regions.LED display can show numeral, literal, the graph image of variation; Not only can be used for indoor environment and can also be used for outdoor environment, have projecting apparatus, video wall, the incomparable advantage of LCDs.Why LED is subjected to extensively paying attention to and is developed rapidly, is that the advantage that had with itself is inseparable.These advantages are summarized: the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and stable performance.
We can recognize in the very general life that has been applied in people of LED display that present application LED technology produced by aforesaid content, it is all rearranged by some led light sources for the LED display of present appearance, as shown in Figure 9, in concrete process of producing LED display employed led light source its structurally generally all comprise LED lamp plate 1, lamp housing 2 and lampshade 3, wherein, LED lamp plate 1 is arranged in the lamp housing 2, lampshade 3 is located on the lamp housing 2, and lamp housing 2 has end face 4.
Thereby aforesaid LED display LED lamp plate 1 in concrete work makes the information that shows the numeral that changes, literal, graph image on the whole LED display according to instruction in conversion between work and the off working state.
The end face 4 of each lamp housing 2 all toward the outer side when above-mentioned led light source is formed LED display, when if end face 4 is the end face of non-black this moment, the color developing effect extreme difference of whole LED display, so the producer needs end face 4 blackings with lamp housing 2 to improve the contrast of LED display when producing LED display, make the display effect of display screen integral body more clear, picture is more beautiful.
But in the process of specifically carrying out with end face 4 blackings of lamp housing 2, because the lampshade 3 of led light source generally all is the structure that adopts the semicircle optical lens of projection, so its production technology is all quite complicated in the process of carrying out concrete blacking, perhaps only be to utilize artificial mode to carry out the blacking operation, this mode of production not only low whole simultaneously product quality of production efficiency also is not easy controlledly, and this is the major defect for conventional art.
Summary of the invention
The invention provides a kind of led light source dirty oil pad printing method, the process of method of the present invention for dirty oil is smeared on the led light source surface, by method of the present invention, bat printing equipment and supporting tool, can will smear dirty oil on the led light source surface in batches on a large scale, improved the efficient and the production capacity of producing, and this is to be main purpose of the present invention.
The technical solution used in the present invention is: it comprises the steps: a kind of led light source dirty oil pad printing method the first step, some led light sources is arranged on the light source set support.
This light source set support is provided with some screens, by this screens some these led light sources are arranged on the light source set support, each this led light source all has the end face of smearing, in the time of when some these led light sources are set at this light source set support by this screens on, this of some these led light sources smeared end face and is positioned on the same horizontal plane.
Second step, some bat printing heads are arranged on the bat printing head bracket, this bat printing head bracket is corresponding with this light source set support in the first step as mentioned above, and this bat printing head bracket is positioned at above this light source set support.
This bat printing head bracket this light source set support relatively pumps, each is arranged on all unique corresponding this led light source that is arranged on this light source set support of this bat printing head on this bat printing head bracket, when relative this light source set support of this bat printing head bracket moves downward, some these bat printing heads move along the direction that this bat printing head bracket moves downward synchronously, this moment, this led light source corresponding with this bat printing head is positioned on the direction of motion of this bat printing head, and each this bat printing head all has the bat printing face.
Smear printing ink on the 3rd step, this bat printing face of this bat printing head in second step as mentioned above, make this printing ink attached on this bat printing face.
The 4th step, will be as mentioned above under 20 degrees centigrade to 30 degrees centigrade operating temperature this bat printing head that is attached with this printing ink in the 3rd step by the driving of this bat printing head bracket to this light source set holder orientation motion, till this that contacts this led light source fully until this bat printing face of this bat printing head smeared end face, this moment, this printing ink is printed on this and smears on the end face.
