Malformation and replacement, be included in protection scope of the present invention.
Referring to Fig. 1, Fig. 1 illustrates a kind of method for designing cold drawing according to an embodiment of the invention.
Step S1, step S2 and step S3 are included according to the method for the present embodiment.Wherein, the method according to the invention is by setting
Meter systems 1 perform.The design system 1 includes acquisition module 101, generation module 102 and adjusting module 103.
In step sl, acquisition module obtains the design information of pcb board corresponding to cold drawing.
Wherein, the design information of the pcb board includes but is not limited to the profile information of the pcb board, dissipating on the pcb board
Hot plug-in element information, and the plug-in element information without radiating on the pcb board.
According to the example of the present invention, with reference to figure 3, Fig. 3 is shown as a kind of to be designed cold described in the embodiment of the present invention
Corresponding to plate, include the pcb board schematic diagram for needing heat dissipation element information.Wherein, it is shown that PCB profile, and wrapped on pcb board
Pinout information corresponding to each heat dissipation element contained.Wherein, the poroid region of white is region corresponding to pin.
Specifically, according in the step S1 of this programme, acquisition module can by importing design documentation corresponding to PCB, and
Every dimension information in the design documentation is read, to obtain the design information of pcb board.
Preferably, the design documentation of pcb board includes but is not limited to CAD documents etc..
Then, in step s 2, generation module is based on the design information, generates the layout information of the cold drawing.
Specifically, generation module carries out conversion operation, to obtain accordingly based on the pcb board design information obtained to it
Cold drawing layout information.
Wherein, the layout information includes but is not limited to：Area of knockout dimension information, heat sink strip positional information etc..
Preferably, generation module is carried out corresponding based on the dimension information in the design information based on predetermined amplification rule
Amplification, to generate layout information corresponding with the cold drawing based on every dimension information after amplification.
Specifically, generation module is based on pcb board design information, it is determined that the pin size of each heat dissipation element included,
And every dimension informations such as the component size of radiating are not required to, and the dimension information to being obtained, entered based on predetermined amplification rule
The corresponding amplification of row, to generate layout information corresponding with cold drawing based on every dimension information after amplification.
It is highly preferred that generation module is based on every dimension information after the amplification, it is determined that generation cold drawing need hollow out area
Domain, to ultimately generate the layout information of cold drawing.
For example, with reference to figure 4 and Fig. 6, generation module can the first design information based on pcb board, it is determined that the profile of corresponding cold drawing
Size.Also, obtain component to be heated and the not dimension information of component to be heated, and based on predetermined amplification that the PCB is included
Rule：Component pin value of magnification：2 millimeters of X axis, 1.5 millimeters of Y-axis；Common components value of magnification：2 millimeters of X axis, Y-axis 2
Millimeter, wherein, the origin of X-axis and Y-axis is the center of each area of knockout.
Then the pin size of each component to be heated is increased by 2 millimeters by generation module respectively on the both sides of X axis, Y-axis
After both sides increase by 1.5 millimeters respectively, the size as corresponding cold drawing area of knockout；And by the component size of not component to be heated
Increase by 2 millimeters respectively on X axis both sides, after increasing by 2 millimeters respectively on Y-axis both sides, as corresponding cold drawing area of knockout
Size.Also, generation module arranges heat sink strip between the pin for the element that need to be radiated, and then generates the layout information of cold drawing.
Then, in step s3, when the layout information is unsatisfactory for predetermined processing request, adjusting module is automatically to described
Layout information is adjusted, to determine that final cold drawing is laid out.
Preferably, design system also includes checking module, and the inspection module is based on the predetermined processing request, automatically to institute
Layout information is stated to be checked.
Preferably, when the presence in the layout information be less than the minimum process spacing it is interregional away from when, check mould
Block removes the machining area.
For example, with reference to figure 5, module is checked according to default minimum process distance values, between each area of knockout
Away from being checked, and (on the left of Fig. 5 institute when being smaller than the minimum process distance values between two area of knockouts are found
Show), region corresponding to the spacing is removed, is also two area of knockout insertions (shown on the right side of Fig. 5).
It is defeated with when the layout information meets the processing request it is highly preferred that design system also includes output module
Go out the final layout information, to design the cold drawing based on the final layout information.The information of output can be CAD or
The data modes such as Gerber.
The method according to the invention, PCB design drawing can be automatically based upon to generate the layout information of cold drawing, efficiency is more
Height, and processing request can be automatically based upon the layout information of cold drawing is checked, more accurately, also, easily facilitate and repair
Change and update the layout information of cold drawing.
In summary, the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
