Description

The method of the auxiliary paint finishing of computer

The present invention relates to a kind of spraying method of surface of the work, the occasion that particularly is suitable for a large amount of productions, difformity workpiece and requires high-quality to spray.

At present, traditional automatic painting method is by operating personnel's field control spray gun, the directly difformity workpiece on transveyer, employing spraying continuously, cause the waste of a large amount of coating, and coating quality also low (surface of the work overbrushing occurs, super is coated with, the many lacquers in edge hang down stream etc.), cause environmental pollution, especially operating personnel are subjected to severe contamination, and labour intensity is bigger simultaneously.

In view of this, the purpose of this invention is to provide the method for the auxiliary paint finishing of a kind of computer,, control the injection of spray gun and the action of control workpiece automatically and match, reach spray gun and spray by desire spraying workpiece shape by the shape of desire spraying workpiece.

The object of the present invention is achieved like this: the step of spraying method:

One. by a shape identification video recorder with workpiece through before the video recorder, convert electronic signal then to, enter image processing;

Two. through the photosignal after the image processing, be transformed into signal that 16 carry computer-readables get through the image processing plate again and be transferred to computer (CPU) and handle;

Three. the matching computer software degree, can import the control coated article to the spray gun distance by keyboard, the state of the art of static size, air pressure size, variable color fast, paint finishing shows, spray gun sprays in advance and postpone to spray the setting and the technology degree of numerical value, and cooperates synchronizing signal computing generation spray gun action diagram.

Four. the directly injection of control commander spray gun from screen.

Owing to adopt such scheme: save coating, and reduce the pollution to environment, the Workpiece painting quality improves, and production efficiency improves, and saves the labour in addition.

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the FB(flow block) of embodiments of the invention.

Among the figure: 1 shape identification video recorder, 2 processor images, 3 screens, 4 computers (CPU), 5 I/O (I/O), 6 spray gun action diagram, 7 spray guns, the input of 8 keyboards, 9 colored screens, 10 conveyer belts and lift.

The method step of present embodiment is as follows:

One. desire is sprayed workpiece made video recording, and convert acceptable electronic signal to, carry out image processing in the processor image 2 and enter through the shape of shape identification video recorder 1 front, workpiece;

Two. the photosignal through after the image processing, be transformed into the signal that 16 carry computer-readables are got through the image processing plate again, transfer to computer (CPU) 4;

Three. the matching computer software degree, control coated articles to the spray gun distance by keyboard input 8, spray compensation number, static size, air are pressed size, colour changing and each operating state demonstration of equipment fast, and the spray gun spraying that sprays in advance or lag behind, be coated with setting value and operational degree, cooperate the synchronizing signal computing.

Four. produce spray gun action diagram 6,, remove directly and control, also can on computer (CPU) 4, freely set, freely spray, the coated article of different geometries by coated article signal detection spraying by spray gun action diagram 6 commander's spray guns 7.

Five. the output signal of I/O (I/O) 5 makes lift drive workpiece enter application through suspension type conveyer belt and lift 10 again.

Six. touch control screen 3 can show all mechanical dynamic, all switches and counter, delayer, all replaces input screens 3 by computer (CPU) 4 and sets and get final product.

Technology degree computer (CPU) 4 is set:

1. spray paint: when selected, can manually select paint to start or static formula or reciprocating engine startup, spraying paint keeps ON when carrying out.

2. clean: when selected, can manually select paint to start, but can't start electrostatic pressure and reciprocating engine.

3. measure: when selected, can manually select paint to start, but stop automatically after 30 seconds, purpose is the individual flows quantitative determination for each rifle, can't start electrostatic pressure and reciprocating engine.

4. electrostatic pressure starts, stops: each rifle is opened electrostatic pressure and switching individually, opens switch, shutdown switch automatically.

5. the paint startup stops: each rifle is opened paint individually, or carries out cleaning, and according to setting scavenging period, unlatching S, A, R, G or regularly measurement are according to top selection.

6. reciprocating engine starts: each reciprocating engine starts individually.

7. reciprocating engine speed is set: each reciprocating engine individual settings speed.

8. conveyer starts: conveyer starts.

9. conveyor speed is set.

10. colour changing fast: by the color in the present use, cut off paint electrostatic pressure and reciprocating engine voluntarily, voluntarily with solvent clean, and it is standby to change second kind of color, so that restart, action is flashed in carrying out.

11. when cleaning: the time of being about to set certainly is divided into five sections cleanings, automatically colour changing is an independent design with each reciprocating engine, as carrying out the NO1 reciprocating engine when C2 changes to C5, cresset moves to C5 from C2, cresset keeps light yellow, and S and A set according to scavenging period, replaces glittering bright entirely to the clean S of full solvent, S extinguishes that to change the new look of C5 glittering, up to setting time C5 filling when finishing, G, R switch, during C5 opens then C5 keep light yellow.

In sum, advantage of the present invention:

1. saving manpower: the employing of automatic coating machine, cooperate the transmission of peripheral conveyer to want to be coated with workpiece, make production line, the scene can be unattended.

2. enhance productivity: overcome the defective of original electrostatic gun work, a same production line can provide 5 times of output.

3. saving coating: the utilization rate of the paint of injection is reached more than 90%.

4. the workpiece coating quality improves: owing to paint is to spray by the shape of workpiece own, so be typically provided with super being coated with, the edge hangs down and flows, so stroke can strengthen, it is very even that track is distributed at workpiece, the thickness height can not occur.

5. the function of spray gun can be given full play to: air gun and airless spray gun are because stroke strengthens well, the stroke spray gun that exceeds is OFF voluntarily, do not have the super phenomenon that is coated with, and the spray paint amount of moment can be improved, intermittent operation makes the selection of spray tip easier, for example there is not the gas jets flow, by the impact of minimum Lei mouth size and minimum effective gasification, pressure, and be limited its minimum output, only had the half the time spraying of original continuous spray spray gun, so easy operating can not flow lacquer.

6. improve production environment, reduce and pollute: the spray paint waste is few, exists the paint of surrounding environment to greatly reduce, thereby reduces environmental pollution.
