Description
Technical field
The utility model relates to silk-screen half tone testing fixture, particularly relates to a kind of silk-screen half tone inspecting lamp case.
Background technology
Silk-screen half tone stretches tight to pull on silk screen and be made on the square metal screen frame that precision is high, silk screen face is coated with emulsion shielded area, offers the opening Printing Zone of circuit, pattern in emulsion shielded area.Metal screen frame is abnormal heavy, and tradition check the opening Printing Zone of circuit on silk-screen half tone, pattern whether complete accurate time, normally artificial then hand steered the opening Printing Zone of wire netting edge edge to circuit, pattern of vertically being placed by silk-screen half tone is observed, this kind of mode labour intensity is large, security is low, silk-screen half tone is easily toppled over and is caused silk screen to burst, and causes production loss.And light when adopting this kind of mode to observe is poor, cannot observe circuit, pattern the details place of opening Printing Zone whether complete, accurate, easily cause bulk printing bad.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of silk-screen half tone inspecting lamp case is provided, the silk-screen half tone solved in current technology is wasted time and energy when checking, cannot observe whether complete, the accurate problem in details place of Printing Zone.
For solving above technical problem, the technical solution of the utility model is:
A kind of silk-screen half tone inspecting lamp case, comprise casing, backlight and glass plate, it is characterized in that, described casing being arranged the placed side of inclination, the bottom of placed side is provided with the rib vertical with placed side, slots in placed side, backlight is had at box house device, the light of backlight is from placed side outgoing, and device glass plate on placed side, silk-screen half tone inclines to leaning against on placed side and checks.Silk-screen half tone inspecting lamp case described in the utility model can be placed on the placed side of casing by needing the silk-screen half tone checked, silk-screen half tone is slant setting and bottom is resisted against on rib, therefore ensure that silk-screen half tone can not landing or topple over when checking, improving the security checking silk-screen half tone.Backlight simultaneously in casing is that silk-screen half tone provides stable illumination, the details place of the Printing Zone on silk-screen half tone can be observed clearly, thus improve the accuracy of silk-screen half tone inspection, ensure the yields of follow-up printing, avoid because flase drop silk-screen half tone causes bulk defective products, effective production control loss.
Further, described backlight is provided with switch control rule to open and close, and device has the slide resistor controlling brightness, the brightness of free adjustment backlight adapts to the demand without employee, avoid the too high wound eye of brightness, also avoid the too low details place that cannot observe Printing Zone of brightness.
Further, between described backlight and glass plate, returning apparatus has diffuser plate, the optical haze utilizing diffuser plate to be produced by backlight, makes the light that appears evenly soft, the eyes of protection staff.
Further, described backlight adopts the some parallel even arrangement compositions of fluorescent tube, and structure is simple, and adopt conventional fluorescent tube namely to can be assembled into backlight, cost is low, changes easy to maintenance.
Further, described backlight adopts matrix arrangement LED particle to form area source, LED particle is low in energy consumption, can effective economize energy, reduce production cost, the dazzling high light that LED particle sends is atomized into soft uniform light through diffuser plate, makes staff can observe the Printing Zone details of silk-screen half tone easily, and avoids human eye to be stimulated by high light and impaired.
Further, described backlight adopts LED particle to be linearly arranged into lamp bar, lamp bar is along light guide plate surface feeding sputtering, the light that LED particle sends can move ahead with total reflection in light guide plate, bottom surface of light guide plate has site by ink printing or etching, the total reflection state of light can be destroyed in site, make light from the upper and lower surface outgoing of light guide plate, the reflecting piece arranged bottom light guide plate makes light all shine diffuser plate from light guide plate upper surface, thus light guide plate converts the line source of lamp bar to area source, adopt this kind of mode can reduce the use amount of LED particle further, maximize the utilization rate of LED particle emergent light, reduce the energy consumption checking light fixture, production control cost.
Compared with prior art, the utility model advantage is:
Silk-screen half tone can be placed on inspection lamp box and check by silk-screen half tone inspecting lamp case described in the utility model, safe to use, silk-screen half tone there will not be the situation of toppling over landing, reduce labour intensity, illumination during inspection is good, and light source stability is good, effectively can observe the Printing Zone details of silk-screen half tone, improve and check precision, improve the judgment accuracy to silk-screen half tone quality, improve printing yields;
The utility model structure is simple, is easy to manufacture, and cost of manufacture is low, high financial profit.
