Technical Field
The invention relates to the field of ship manufacturing, in particular to an automatic painting method for patterns, characters and the like.
Background
With the deep development of the modern shipbuilding mode, the ship types born by Chinese shipbuilding enterprises are continuously abundant, and the forms and contents related to the patterns and characters needing to be sprayed and painted on the steel plates are gradually diversified, complicated and internationalized. The traditional manual painting technology adopts a manual drawing method, the drawn contents are greatly influenced by the skill factors of personnel, and the traditional manual drawing method has the disadvantages of low drawing speed, low efficiency and non-uniform overall aesthetic property. Therefore, the traditional manual spray painting technology mainly adopts a small-batch spray painting mode.
In the face of the trend of China ship manufacturing towards the world, the painting content also tends to be internationalized and diversified, and the manual painting method cannot meet the requirements of complicated and diversified graphs and characters; and the cost of the traditional manual painting is increased continuously due to the increased labor cost, and the painting mode of the traditional manual painting of patterns and characters is not suitable for the mode of continuous painting or mass painting in the current ship market, so that the requirement of the ship market for rapid development cannot be met.

In step 3, the numerical control cutting machine imports the powder spraying program formed in the step 2, conducts powder spraying instruction import, conducts graph and character drawing before cutting according to cutting operation, cancels the cutting operation after completing the graph and character drawing, starts spray painting operation and automatically spray paints patterns.
The invention has the advantages that: automatic pattern and character spray painting is realized based on CAD (computer-aided design), NESTING (Nesting software) and a numerical control cutting machine, the spray painting is simple, convenient and efficient, the spray painting error rate is low, the requirement of mass production spray painting can be met, and the spray painted pattern and character can be modified and the diversity of various spray painting contents can be met.
Drawings
The contents of the expressions in the various figures of the present specification and the labels in the figures are briefly described as follows:
FIG. 1 is a schematic flow chart of the automatic inkjet printing method according to the present invention.
Detailed Description
The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.
The technical problem to be solved by the invention is as follows: how to realize the quick and effective work of drawing the plate patterns and characters by code spraying and meet the diversity of the painting contents; meanwhile, errors and drawing cost generated in the manual drawing process are reduced, and automatic drawing of plate figures and character code spraying is realized.
In order to solve the technical problems, the technical scheme of the invention is as follows: the method comprises the steps of importing or drawing needed graphs and characters in CAD software, importing NESTING software, forming a cutting machine language recognizable program by using a NESTING and scribing principle of the NESTING software, and realizing automatic drawing of the imported graphs and characters by using a numerical control cutting machine to spray powder.
The specific implementation mode of the invention is as follows: as shown in the figure, the system consists of 3 main phases (preparation phase, specific operation phase, drawing phase); mainly using software and equipment: CAD, NESTING, and numerical control cutting machine (including powder spraying and scribing functions).
Step 2 is a specific implementation stage, and is mainly used for forming a powder spraying program of the numerical control cutting machine in NESTING. Firstly, redefining lines of a CAD file in NESTING, and adjusting the lines to be dotted and drawn lines required by a powder spraying program; secondly, manufacturing set parts (Nest → Nesting tools → parts → defining part requirements) by painting figures and characters, wherein if the step of 'HOLE' exists, the step can not be realized, and the previous layer of processing is required to be carried out again; then, performing part Nesting operation (creating a mother board → Nest → Nesting parts → Nest → 1.By name → inserting the manufactured part), adding a powder spraying starting point (Nest → Nesting tools → start → Mark → Single) to the Nesting part, and adding powder spraying points (or automatically adding) to all continuous lines one By one; and finally, outputting the marking program to a numerical control cutting machine.
And step 3 is a drawing stage, which is mainly used for automatically drawing figures and characters. And (3) introducing a powder spraying instruction in a numerical control cutting machine, drawing figures and characters before cutting according to conventional cutting operation, canceling the cutting operation after finishing drawing the figures and the characters, and finishing the automatic drawing of the figures and the characters required.
In the actual production process, when the spray-painted patterns are determined for the first time, all the steps 1, 2 and 3 need to be executed, and when the spray-painted patterns are sprayed in batches, after the powder spraying program corresponding to the numerical control cutting machine is generated in the steps 1 and 2, the powder spraying and line drawing function of the numerical control cutting machine can be used repeatedly to realize the drawing.
The invention has the characteristics that: the drawing system realizes the rapid and accurate painting of various figures and characters, has the characteristics of good quality, high efficiency, high speed and rich drawing content, is convenient to implement and simple to operate, and can meet the requirements of drawing content in various sizes and styles. The invention is successfully applied in the process of building the ship in the department series, and the effect is very ideal.
It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
