Description

Automatic spraying mechanism

【Technical field】

The utility model relates to a spraying mechanism, in particular to an automatic spraying mechanism arranged on a base corresponding to a plurality of rotatable support rods.

【Background technique】

Generally, traditional spraying operations can be completed with manual hand-held spray guns. The advantage of this method is that the spraying direction can be adjusted arbitrarily, and it is not easy to cause incomplete spraying due to dead angle positions; however, the operation is inconvenient and time-consuming.

The use of automatic spraying equipment can make the spraying operation more convenient and time-saving; however, most general spraying equipment provides three-axis spraying directions of X, Y, and Z. When performing spraying operations, it is easy to cause spraying dead ends due to the shape of the workpiece. Although the direction and position of spraying can be improved by the rotation or displacement of the workpiece, there will still be incomplete spraying.

In addition, most of the general spraying equipment places the object to be sprayed in a fixed position. Even if the aforementioned three-axis spraying equipment is used for spraying, the backside of the object to be sprayed cannot be effectively sprayed.

【Content of invention】

The main purpose of the utility model is to provide an automatic spraying mechanism, which has the functions of simple structure and easy operation.

The utility model is achieved in this way, an automatic spraying mechanism, which includes a stand; a spraying device is arranged on the stand and has a spray head; a driving device is arranged on the stand and combined with the spraying device, which is a servo The motor is connected with a screw, and a driven block is engaged with the screw and combined with the spraying device, so that the action of the servo motor and the screw can drive the driven block and the spraying device to produce linear reciprocating movement, so as to achieve the effect of automatic spraying.

The utility model has the effects of simple structure and easy operation.

【Detailed ways】

Please refer to FIG. 1 , which discloses an automatic spraying mechanism, which includes a stand (10), a spraying device (20) and a driving device (30).

A stand (10) foot comprises a first board body (11) and a second board body (12), and plural upright rods (13) are set on the first board body (11) and the second board body (12) Between, and a rail piece (14) is arranged between the first plate body (11) and the second plate body (12) parallel to each upright bar (13). In addition, a pair of restricting rails (15) is arranged on the rail member (14).

A driving device (30) is to comprise the combination of a servomotor (32) and a screw rod (34); A driven block (36) has a threaded hole (37), and the screw rod (34) passes through the threaded hole (37) to Engage driven block (36). In addition, a driven block (36) may be arranged between the pair of restricting rails (15).

Please refer to Fig. 2, the spraying device (20) has at least one spray head (21). In addition, the spraying device (20) is combined with a connecting block (22) to the driven block (36).

Referring to Fig. 3, when the output power of the servo motor (32) is to drive the screw rod (34) to rotate, the driven block (36) engaged on the screw rod (34) produces linear displacement along the axial direction of the screw rod (34). Therefore, the spraying device (20) combined with the driven block (36) can also be linearly displaced.

Since the driven block (36) is disposed between the pair of restricting rails (15), the driven block (36) can be restricted from rotating and can be reliably displaced.

Please refer to Fig. 4, about the use of automatic spraying mechanism, be that the combination of stand (10), spraying device (20) and driving device (30) is configured on a base (40); The seat (40) has a rotatable turntable (42), and a plurality of struts (44) are assembled on the turntable (42). Each pole (44) can be driven to rotate by itself. In addition, the combination of the stand (10), the spraying device (20) and the driving device (30) is fixedly assembled on the base (40) and does not rotate.

Place the object to be processed (not shown) on the pole (44), and the turntable (42) can rotate the pole (44) and the object to be processed; when the object to be processed is opposite to the nozzle (21), the nozzle (21) paint can be sprayed on the surface of the object to be processed; because the spraying device (20) can be used for lifting displacement and can be rotated to be processed, the paint can be evenly and completely attached to the surface of the object to be processed.

Referring to Fig. 5, a protective cover (50) is assembled on the stand (10) and opposite to the screw rod (34). More specifically, the protective cover (50) is assembled on one side of the rail member (14) to face the screw rod (34), so as to prevent the paint slag generated by the spraying operation from falling on the surface of the screw rod (34). The cover (50) can be a rubber sheet or a metal sheet.

Because the utility model combines a driven block (36) with the screw rod (34), and the driven block (36) is combined with the spraying device (20), so the structure is simplified, and the driving screw rod (34) can make the spraying device (20) For lifting movement, so easy to operate.
