Abstract
The invention relates to a rotary automatic coating method, which is characterized in that: a rotary coating can be implemented by reducing the interval configuration of the object to be coated in relation to the side of the coated object with more coating, so the coated object in the front can be covered. The workpiece pitch at an adjacent flat is less than the workpiece pitch at the flat in relation to the coating object arranged on the flat. As an alternative method, a rotating device for straight line movement area is arranged at the spraying and coating area, and the rotating device is rotated without the influence of spraying angle. The rotary automatic coating method has the advantages of maintaining the effect of rotary coating, and improving the uniformity of the paint film and the coating quality .
Description
Technical field
The present invention relates to occasion that less coated objects such as many mobile phones, camera are carried out application, coated object is configured in the rotary application of carrying out application on the workbench of rotation circle-shapedly.Especially relate to respect to the spray gun that is configured, utilize coated object to carry out application with the different angle of application face, the different occasion of thickness can be to the technology of its coating process improved and device thereof.
Background technology
Rotary application, as during the rotation of the coated object arranged on the circumference, utilize gun spraying, to the method that the coated object that and then enters the application spray area carries out application, productivity is very high, is used to many aspects.The method of application and condition, select according to the film quality of the shape of coated object and requirement, coating etc., but generally be to adopt coated object put on the coated object anchor clamps that are disposed at around the rotary table to make it with respect to rotating shaft eccentric, the operation of spraying towards the direction of spray gun, and will rotate the operation of spraying equally of reversing and carry out application, the left and right side of coated object is carried out the method for even application.
Changing the method that direction of rotation is carried out application, because of the coated situation difference of the different coating of direction of rotation, is necessary therefore, except flat uniform thickness is required is not the too high occasion, adopts the means of rotary application usually mostly.
In addition, the coated object that puts abreast with tangent line of circle-shaped configuration has the occasion of male and fomale(M﹠F), and the side of coated object is the coated surface of being sprayed by spray gun 11 in right side and left side, and angle becomes different states.That is, as shown in Figure 2, the coated object 10 with width is rotated under the stationary state on the workbench of rotation, so the angle Y when angle X when the A face in the face of being coated with of coated object 10 is coated and B face are coated has nothing in common with each other.
In spraying, be coating thickness with respect to the coating efficiency of the application face of coated object, be subjected to be coated with jet length till the face, by the speed that is coated with face in other words be coated with ETL estimated time of loading and with the influence of the angle that is coated with face.In the example of Fig. 2, jet length, be coated with and almost do not have difference on the ETL estimated time of loading, and there is very big-difference in spray angle, difference occurs on the thickness that its result films.Certainly, the coating efficiency height vertical with the face that is coated with, the A face is thick, and B is many because of the spray coatings particle runs off, thickness is thin.
In the following operation, shown in dotted line, the occasion of application is carried out in reverse rotation, and B ' is thick, and A ' is coated with thinly.Therefore, occasion of coated object so, inboard side attenuation becomes and lacks inhomogeneity application fine finishining.Although there is the difference of coated weight too in the difference of the spray angle pair face parallel with rotation round, by the application of reversing, its result becomes uniform thickness, and therefore as mentioned above, the facade of coated object is the thickness existing problems of side.
In addition, the occasion that coated object is littler according to situation of subsequent processing etc., has to a plurality of coated objects are configured on 1 flat board through regular meeting, should flat board puts to carry out application on rotary table circle-shapedly.This occasion as shown in Figure 6, has put the occasion of coated object 3,4 on anchor clamps 6, identical with above-mentioned situation, the thickness difference of the left and right side of each coated object.
The inhomogeneities that the difference of coating thickness causes can become the different reasons of coating quality such as being coated with face gloss, color, also can become to produce the bad reason of processing etc. when application face carried out secondary operations, and be the reason that produces many problems.
If the coated object of circle-shaped configuration is carried out application with respect to spray gun with identical angle, such problem just can improve, but needs like this to strengthen rotary table, is subjected to the restriction of equipment, in fact is difficult to employing, also practicability not.
In view of this, the object of the present invention is to provide in a kind of rotary application and keep under the productive situation, improve the above-mentioned key technology that the shape because of coated object causes, make coating process that forms uniform thickness on each application face and the device of being convenient to implement.
Content of the present invention
In order to achieve the above object, the present invention during many coated objects repeat to turn-take, the direction of utilizing spray gun to come towards coated object carries out in the rotary application of atomized spray painting, because of making the angle of application face, the position of rotation that enters the coated object that is coated with holding position on the circumference successively changes, the occasion that coating thickness is different, big the place ahead of angle of the application facade (side) of the coated object of coming over, make the local configuration of covering in the rear that is reduced by same angle and make its rotation, carry out application.
One of method of the configuration of covering as the part, a plurality of coated objects are put in the plane many occasions that are configured on the circumference of anchor clamps, to put on adjacent anchor clamps and the interval of the coated object that adjoins each other, set for littler than the interval of the adjacent coated object on the same plane.Thus, put the coated object in the place ahead of anchor clamps in the wings, little with the distance of the coated object at the rear of the coated object that is configured in the place ahead, obtain local the coverage from the spraying of spray gun, the chance of coating reduces, and thickness is restricted.
In addition, other method, with the planar portions of anchor clamps on the circumference of rotation when the outside is configured, the rear positions of anchor clamps is with respect to the front portion, be set in the position away from the center of rotation, to be configured, the front part that is right after anchor clamps in the wings is divided into the state of avoiding spray flow with having angle slightly, same as described above, can reduce the chance of coating.
As another device of the present invention, be provided with the straight line moving section in the part of the device of the anchor clamps of the coated object that many coated objects are turn-taked rotation, so that do not change by the face-off angle of coated object during the application zone and spray gun.As painting device, its whirligig is arranged to a pair of whirligig of the positive and negative both direction rotation of energy, the spray gun that to spray with certain angle from the opposite side of direct of travel is configured in respectively in the described straight line moving section of these two whirligigs, thereby carries out application.

The specific embodiment
Below, the invention to motion of the present invention describes with reference to accompanying drawing.As the Fig. 1 shown in the example of rotary application, on the anchor clamps 6 of the circle-shaped workbench 5 that is disposed at rotation, respectively install 2 by the coated object 3,4 of spray gun 2 applications.Anchor clamps 6 are tabular, install abreast with its tangent line on the concentric circles of above-mentioned workbench 5, and dismounting freely as required.This example is the example that 8 anchor clamps 6 have been installed.
The direction that position and spraying axle are set of spray gun is arranged on and departs from abreast from the center of rotation and on the eccentric position, become coated object from oblique position relation of carrying out application.And the top and bottom of coated object need the occasion of application, as mentioned above, spray gun are sprayed under the state that has angle up and down, but do not have direct relation with aim of the present invention, adopt as required.
Among Fig. 1, coated object is towards anticlockwise, and spray gun is configured in the left side of rotating shaft, towards coated object right flank 3A, 4A and front is carried out application.The position that left figure expression application face 4A is coated, the postrotational application face 3A of right figure expression is coated with the state of holding position.The application of left surface makes coated object towards right rotation not shownly, and spray gun is configured in the right side of rotating shaft, towards the direction application left side of coated object.For 1 coated object, application is carried out in each position during rotating a few, finish the fine finishining of filming.The thickness of filming by common test application, is set at best application condition by decisions such as the spray volume that is coated with ETL estimated time of loading, coating, application distances.
The configuration that focuses on anchor clamps and coated object of the present invention.That is, be installed in the place ahead application face 3A of the coated object that is introduced into the application zone in the coated object on the tabular, big with respect to the angle of spraying axle, apply effective.By contrast, the place ahead application face 4A of the coated object that enters the application zone thereafter on the same anchor clamps is little with respect to the angle of spraying axle, applies weak effect.Therefore,, then directly become the difference that applies effect, become the unbalanced application of thickness if be configured to the mutually noninterfere of common coated object phase.
Method of the present invention, dwindle at interval so that when the application face of first application enters the application zone on the same anchor clamps, coated object on the anchor clamps that are installed in the front is stayed in the application zone, being coated with ETL estimated time of loading or receiving the ratio of spray particle of reality by reducing above-mentioned application face, reduce the thickness that applies, on each coated object, obtain uniform thickness as a whole.Promptly, put the occasion of 2 coated objects on the same anchor clamps, as shown in Figure 1, the interval P2 between the coated object on the adjacent anchor clamps is configured to littler than the interval P1 between the coated object on the same anchor clamps, by so rotary application, can obtain the application face of uniform thickness.
The applicant of this case invention, in the example of the coated object of Fig. 6, with the fixed interval of the coated object on the same anchor clamps at 32mm, with the interval X of adjacent coated object by change and carry out application shown in Figure 3ly, Thickness Variation to coated object 3 and 4 is confirmed, consequently, found the difference of coating thickness shown in Figure 4.From this figure as seen, during same intervals, still the thickness in the place ahead is big, but according to the interval of the coated object on the same anchor clamps 3 and 4, the interval X of the coated object on the adjacent anchor clamps becomes roughly thickness uniformly near 30mm.The further occasion that shortens, the thickness attenuation on the contrary of the coated object 3 in the place ahead.
The intensity of variation of the coating thickness that coated object causes at interval, the influence that the width of the spray pattern that causes with the various conditions of the shape that comprises coated object etc., because of spray gun etc. is covered is different, and need narrowing down, what should be selected according to result of the test.
In addition, as other embodiment motions Fig. 5.That is, the anchor clamps that put coated object are configured on the circumference, and be configured to with having angle with respect to direction of rotation, the place ahead towards the central side of rotation and the rear towards the outside of rotation, make distance X 1 littler than distance X 2.Therefore, towards the coated object 3 that the spray gun 11 of spraying enters, inwards introduce in the place ahead, and the coated object 4 or the anchor clamps 6 that are put on the anchor clamps 6 in front itself are covered, so be coated under the state that can not receive sufficient spraying.
Such occasion, the thickness that the degree that tilts according to anchor clamps applies changes, and the place ahead is because of big with respect to the spray angle of application face, so the amount that applies is many, but the phase counter regulation that coated object by being configured in its front or anchor clamps carry out can obtain uniform coating thickness as a whole.
Below, the 2nd invention of motion of the present invention, as shown in Figure 7, be one with the coated object of the spray gun face-off rotary painting device that straight line is rotated movably during by the application zone at least, the anchor clamps 21 of coated object 20 are installed on the whirligig 24 that connects the chain form that 2 rotating discs 22,23 are rotated, and mobile limit on the Long Circle with straight line moving part, limit repeats rotation.Rotating disc 22,23 both can be rotated synchronously by 1 drive unit, also above-mentioned whirligig 24 can be used for to drive to transmit key element, can be made of well-known driving mechanism.Spray gun 25 is configured on the spray position of line part 24, is arranged to usually have angle with respect to direct of travel.
For coated object, spray gun 25 is set down with respect to above-below direction and it is moved towards the below, to comprise coated object 20 above carry out application, set up and it moved towards the top, to comprise coated object 20 below carry out application.These spray gun driving methods drive control by paint robot, are as the employed method of general robot painting.
In the present embodiment, the whirligig that will be made of above-mentioned a pair of rotating disc and whirligig can positive and negative rotation one and is set up in parallel, and repeats during the rotation coated object to be carried out application at two whirligigs.Thus, thus coated object forms required thickness during the several years are by spraying area while rotating finish application.Move with same angle with respect to spray gun in during by spraying area,, do not have Thickness Variation, can obtain uniform fine finishining so can guarantee to be coated with the condition of face position equally.And, can keep the advantage of the high rotary application of productivity, can carry out application to many coated objects efficiently.
