Description
Technical field
The present invention relates to a kind of guide-lighting board machining process more particularly to one kind to cast guide-lighting board machining process.
Background technique
The principle of luminosity of light guide plate is that the light issued using LED carries out diffusing reflection in plate surface, by changing site
Size (printing process), density degree (hot pressing processing procedure) destroys the delivering path of light, thus improving optical uniformity and bright
Degree, the technique for generalling use two-sided hot pressing currently on the market carry out optical brightness promotion, and upper roller uses steel plate, and bottom roll uses
V-CUT backing plate carries out two-sided hot pressing, wherein the steel plate of upper roller is mainly thermal transfer site, relatively conventional net on the market at present
Point structure is exactly round volcanic crater, and the corresponding steel plate processing of this structure is processed by laser form, however as bright
Desired promotion is spent, conventional circular shaped lattice point structure is no longer satisfied requirement, so to use the site of special shape
Structure, such as asymmetric pyramid shape, however its steel plate of the site of this structure is processed into a technological difficulties.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, one kind is provided and casts guide-lighting board machining process, passes through gold
It has just bored cutting technique and has carried out tool sharpening, then carried out steel plate processing in the form of hitting a coordination galvanization and casting again, thus real
The processing of existing special lattice point structure.
To achieve the above object, the following technical solutions are proposed by the present invention: one kind casting guide-lighting board machining process, the two-sided knot
The light-emitting surface of structure light guide plate has site, and opposite bottom surface has V-cut structure, and the processing step includes:
A, tool sharpening: spark is cut according to cutter drawing；
B, steel plate is hit a little: by the Cutting tool installation manner to percussion device processed, and being installed steel plate in equipment, is existed using impact force
Surface of steel plate hit the concave point for a little forming that and depth consistent with the shape of tool is 15um one by one, controls knife in knockout process
Tool is 90 ° with steel plate angle；
C, plating is cast: the step b steel plate processed being placed in electroplating bath, and is passed through 2A ~ 100A electric current in electroplating bath, is led to
Electric 5 ~ 5.5h of time reprints out dot shape in concave point position on the steel plate using plating form processing；
D, transfer processing, the step c steel plate processed is installed on idler wheel, while will be placed on backing plate after light guide plate dyestripping
On, control steel plate pushes after being directed at position, and upper and lower extruding force is transferred to the lattice point structure of top on light guide plate, wherein machine
Platform pressure value is 1.0 ~ 2.2 tons；Upper roller temperature is 105 DEG C ~ 130 DEG C, and bottom roller temperature is 50 ~ 80 DEG C.
Preferably, the cutter be pyramid shape, four be respectively the first seamed edges, the second seamed edge, third seamed edge and
4th seamed edge, the length of four seamed edges are respectively L1, L2, L3, L4, and L1 < L3 < L2=L4.
Compared with prior art, disclosed one kind casts guide-lighting board machining process, has the following beneficial effects:
Tool sharpening is carried out by spark cutting technique, then carries out steel plate processing in the form of hitting a coordination galvanization and casting again,
To realize the processing of special lattice point structure.
Detailed description of the invention
Fig. 1 is cutterhead structural schematic diagram of the present invention.
Specific embodiment
Below in conjunction with attached drawing of the invention, clear, complete description is carried out to the technical solution of the embodiment of the present invention.
As shown in Figure 1, disclosed one kind casts guide-lighting board machining process, it is asymmetric tetragonous mainly for having
The processing of the light guide plate of taper lattice point structure, specific processing step include:
A, tool sharpening: spark is cut according to cutter drawing；
B, steel plate is hit a little: by the Cutting tool installation manner to percussion device processed, and being installed steel plate in equipment, is existed using impact force
Surface of steel plate hit the concave point for a little forming that and depth consistent with the shape of tool is 15um one by one, controls knife in knockout process
Tool is 90 ° with steel plate angle；
C, plating is cast: the step b steel plate processed being placed in electroplating bath, and is passed through 2A ~ 100A electric current in electroplating bath, is led to
Electric 5 ~ 5.5h of time reprints out dot shape in concave point position on the steel plate using plating form processing；
D, transfer processing, the step c steel plate processed is installed on idler wheel, while will be placed on backing plate after light guide plate dyestripping
On, control steel plate pushes after being directed at position, and upper and lower extruding force is transferred to the lattice point structure of top on light guide plate, wherein machine
Platform pressure value is 1.0 ~ 2.2 tons；Upper roller temperature is 105 DEG C ~ 130 DEG C, and bottom roller temperature is 50 ~ 80 DEG C.
The cutter be pyramid shape, four be respectively the first seamed edge, the second seamed edge, third seamed edge and the 4th seamed edge,
The length of four seamed edges is respectively L1, L2, L3, L4, and L1 < L3 < L2=L4.
