[0020] 1.

[0021] 2. The spraying machine for automobile interior decoration described in the present invention utilizes an adjustable elastic splash-proof mechanism.

Moreover, when the telescopic plate slides on the fixed plate, the two ends of the cushion will be stretched, and its length will change in real time according to the displacement of the telescopic plate. When the frame descends, the cushion will contact the surface of the plate, and the cushion will be deformed under the action of extrusion, so that the cushion is in close contact with the curved surface of the plate, thereby reducing the gap between the entire enclosure and the plate. It avoids the situation that when the fixed plate, the telescopic plate contact the plate on the curved surface, a gap appears between the plate surface and the fixed plate, the telescopic plate, and then the paint splashes from the gap to the non-spraying area, affecting the spraying quality. In addition, the soft pad can be disassembled and replaced with the cooperation of the connecting block 1, the connecting block 2 and the bolt, thereby ensuring the use effect of the soft pad and avoiding the situation that the paint remaining on the surface of the soft pad adheres to the surface of other parts during subsequent use due to the adhesion of more paint to the soft pad. In addition, when the curvature of the curved surface of the workpiece is large, and the middle part of the soft pad first contacts the convex part of the curved surface, and the two ends of the soft pad cannot fit tightly with the surface of the workpiece, the connecting block 3 can be driven down, and the two ends of the soft pad can be driven down by the insertion rod to make the soft pad bend with the curvature of the curved surface of the workpiece to fit tightly with the surface of the workpiece, thereby avoiding the situation that the two ends of the soft pad cannot fit tightly with the surface of the workpiece due to the large curvature of the curved surface of the workpiece and the soft pad first contacts the convex part of the curved surface, which affects the enclosure effect, and further improves the interception effect of splashed paint.

[0045] Specifically, the existing automobile interior spraying device uses a nozzle to spray the workpiece during use. During the spraying process, paint splashes may occur. When only part of the workpiece needs to be sprayed, the paint may splash to the area that does not need to be sprayed, thereby affecting the accuracy and consistency of the spraying and reducing the spraying quality.

[0046] Therefore, in order to solve the above problems, this embodiment is used for plate workpieces in automobile interior decoration, such as door inner guard plates, sun visors, etc., and various types of plates are used in the manufacturing process of these workpieces; after the workpiece is fixed, the mechanical arm 5 can be used to drive the spray gun 28 to move flexibly. The mechanical arm 5 is a prior art and will not be described in detail. Then, the paint in the paint box 25 is pumped out through the pump body 26, and sprayed out from the spray gun 28 after passing through the hose 27 to spray the surface of the workpiece;

[0047] When only part of the workpiece needs to be sprayed, according to the size of the spraying area, multiple cylinders 3 32 are started at the same time to drive multiple fixed plates 15 to move simultaneously, so that the multiple fixed plates 15 are close to or away from each other, and the motor 4 20 is used to drive the connecting rod 1 16 to rotate, so that under the action of the gear 33, the two adjacent connecting rods 1 16 can rotate in different directions at the same time, and the connecting rod 2 30 rotates. When the angle between the connecting rod 1 16 and the connecting rod 2 30 changes, the telescopic plate 17 can slide inside the fixed plate 15, and a rectangular enclosure can be formed by fitting the edges of the adjacent telescopic plates 17, and, The area of ​​this rectangle can be adjusted according to the area to be sprayed. Under the premise of not affecting the normal spraying work, the area of ​​the entire enclosure can be reduced as much as possible to enclose the spraying area. In addition, the motor three 8 drives the threaded rod two 7 to rotate, the motor two 6 drives the threaded rod one 2 to rotate, and the cylinder one 10 drives the frame 12 to rise and fall. The position of the frame 12 in the XYZ axis direction can be adjusted to make the enclosure fit the surface of the workpiece. At this time, when spraying is carried out, the splashed paint will be intercepted by the enclosure, which can avoid the situation where the paint splashes to the area that does not need to be sprayed, ensure the accuracy and consistency of spraying, and improve the spraying quality.

[0048] Since some of the plates have a certain curvature, and the bottoms of the fixed plate 15 and the telescopic plate 17 are flat, when the fixed plate 15 and the telescopic plate 17 are in contact with the curved surface of the plate, a gap will appear between the surface of the plate and the fixed plate 15 and the telescopic plate 17, and then the paint will splash out from the gap to the non-spraying area, affecting the spraying quality. Therefore, in order to avoid the above situation, when the telescopic plate 17 slides on the fixed plate 15, since the insertion rod 22 is plugged into the end of the soft pad 19, the two ends of the soft pad 19 will be stretched, and its length will change in real time according to the displacement of the telescopic plate 17. When the frame 12 descends, the soft pad 19 will contact the surface of the plate, and the soft pad 19 will produce under the action of extrusion. The soft pad 19 is deformed so that it is in close contact with the curved surface of the plate. The soft pad 19 can be squeezed to reduce the gap between the entire enclosure and the plate, thereby avoiding the situation that when the fixed plate 15 and the telescopic plate 17 are in contact with the curved surface of the plate, a gap appears between the plate surface and the fixed plate 15 and the telescopic plate 17, and then the paint splashes from the gap to the non-spraying area, affecting the spraying quality. In addition, the soft pad 19 can be disassembled and replaced with the cooperation of the connecting block 1 23, the connecting block 24 and the bolts, thereby ensuring the use effect of the soft pad 19 and avoiding the situation that the paint remaining on the surface of the soft pad 19 adheres to the surface of other parts during subsequent use due to the adhesion of more paint to the soft pad 19.

[0049] However, when the curvature of the curved surface of the workpiece is large and the middle part of the soft pad 19 contacts the raised part of the curved surface first, the two ends of the soft pad 19 cannot fit tightly with the surface of the workpiece, affecting the enclosure effect. Therefore, when the above situation occurs, the cylinder 2 18 can be used to drive the connecting block 3 21 to descend, and the plug rod 22 can be used to drive the two ends of the soft pad 19 to descend, so that the soft pad 19 can be bent along the curvature of the curved surface of the workpiece and further fit tightly with the surface of the workpiece, thereby avoiding the problem that the curved surface of the workpiece is large and the soft pad 19 contacts the raised part of the curved surface first, which causes the two ends of the soft pad 19 to be unable to fit tightly with the surface of the workpiece, affecting the enclosure effect, and further improving the interception effect of splashed paint.

[0050] Working principle: Place the plate to be sprayed between the two positioning plates 14, then start the motor 14 to drive the bidirectional threaded rod 13 to rotate, so that the two positioning plates 14 can slide simultaneously and approach each other to clamp and fix the plate, thereby ensuring the stability of the plate during the spraying process. When the workpiece is fixed, the mechanical arm 5 can be used to drive the spray gun 28 to move flexibly. The mechanical arm 5 is a prior art and will not be described in detail. Then, the paint in the paint box 25 is extracted through the pump body 26 and sprayed from the spray gun 28 through the hose 27 to spray the surface of the workpiece; when the workpiece only needs to be sprayed partially, according to the size of the spraying area required, start multiple cylinders 32 at the same time to drive multiple fixed plates 15 to move simultaneously, so that the multiple fixed plates 15 are close to or away from each other, and the motor 4 20 is used to drive the connecting rod 16 to rotate, so that under the action of the gear 33, the two adjacent connecting rods 1 6 rotates in different directions at the same time, and the connecting rod 2 30 rotates. When the angle between the connecting rod 1 16 and the connecting rod 2 30 changes, the telescopic plate 17 can slide inside the fixed plate 15, and a rectangular enclosure can be formed by fitting the edges of the adjacent telescopic plates 17. Moreover, the area of ​​the rectangle can be adjusted according to the area to be sprayed. Under the premise of not affecting the normal spraying work, the area of ​​the entire enclosure can be reduced as much as possible to enclose the spraying area. Moreover, the motor 3 8 drives the threaded rod 2 7 to rotate, the motor 2 6 drives the threaded rod 1 2 to rotate, and the cylinder 10 drives the frame 12 to rise and fall. The position of the frame 12 in the XYZ axis direction can be adjusted to make the enclosure fit the surface of the workpiece. At this time, when spraying is carried out again, the splashed paint will be intercepted by the enclosure, which can avoid the situation where the paint splashes to the area where spraying is not required, thereby ensuring the accuracy and consistency of spraying and improving the spraying quality.Since some plates have a certain curvature, and the bottoms of the fixed plate 15 and the telescopic plate 17 are flat, when the fixed plate 15 and the telescopic plate 17 contact the curved plate, a gap will appear between the plate surface and the fixed plate 15 and the telescopic plate 17, and then the paint will splash from the gap to the non-spraying area, affecting the spraying quality. Therefore, in order to avoid the above situation, when the telescopic plate 17 slides on the fixed plate 15, the insertion rod 22 is plugged into the end of the soft pad 19, so the two ends of the soft pad 19 will be pulled The length of the telescopic plate 17 changes in real time according to the displacement of the telescopic plate 17. When the frame 12 descends, the soft pad 19 contacts the surface of the plate, and the soft pad 19 is deformed under the action of extrusion, so that the soft pad 19 is in close contact with the curved surface of the plate. The gap between the entire enclosure and the plate can be reduced by squeezing the soft pad 19, thereby avoiding the occurrence of a gap between the plate surface and the fixed plate 15 and the telescopic plate 17 when the fixed plate 15 and the telescopic plate 17 contact the curved surface of the plate, and then the paint splashes from the gap to the non-spraying area. domain, affecting the spraying quality, and, with the cooperation of the connecting block 1 23, the connecting block 24 and the bolts, the soft pad 19 can be disassembled and replaced, ensuring the use effect of the soft pad 19 and avoiding the situation that the paint remaining on the surface of the soft pad 19 adheres to the surface of other parts during subsequent use due to the adhesion of more paint to the soft pad 19; and when the arc surface of the workpiece has a large curvature and the middle part of the soft pad 19 contacts the convex part of the arc surface first, it will cause the two ends of the soft pad 19 to be unable to fit closely with the surface of the workpiece, affecting Therefore, when the above situation occurs, the connecting block 3 21 can be driven down by the cylinder 2 18, and the two ends of the soft pad 19 can be driven down by the plug rod 22, so that the soft pad 19 can be bent along the curvature of the workpiece surface, and further fit closely with the workpiece surface, thereby avoiding the situation that the two ends of the soft pad 19 cannot fit closely with the workpiece surface due to the large curvature of the workpiece surface and the soft pad 19 first contacts the convex part of the curved surface, thus affecting the effect of the enclosure effect, and further improving the interception effect of the splashed paint. ;
