Automatic angle adjusting system for spray guns

Abstract

The invention relates to the field of spraying equipment, in particular to an automatic angle adjusting system for spray guns. The automatic angle adjusting system for the spray guns comprises a first linear guide rail, a controller and at least one spray gun unit. Each spray gun unit comprises the corresponding spray gun, a rotation adjusting mechanism, a first connecting base and a first marking mechanism, wherein the spray gun is installed on the rotation adjusting mechanism connected with the controller, and the rotation adjusting mechanism can be controlled by the controller to automatically adjust the jetting angle of the spray gun; the rotation adjusting mechanism is installed on the first linear guide rail through the first connecting base, the first connecting base can move along the first linear guide rail, the rotation adjusting mechanism can rotate and conduct vertical adjustment on the first connecting base, and the first marking mechanism is used for marking the rotation angle and the vertical adjustment position of the rotation adjusting mechanism on the first connecting base. According to the automatic angle adjusting system for the spray guns, the scheme of automatic spray gun angle adjustment and manual spray gun position adjustment is adopted, free adjustment of the spray gun position and angle is achieved, and the production cost and the control difficulty are reduced.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a spray gun angle automatic adjustment system. Background technique [0002] Spraying is a coating method in which spray guns or disc atomizers are dispersed into uniform and fine droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. In order to achieve a comprehensive spraying on the surface of the workpiece, the workpiece and / or the spray gun need to be moved during the spraying process. In the prior art, since the spray gun generally does not have an automatic adjustment device, the nozzle of the spray gun generally cannot be rotated. Therefore, most of them rely on manual hand-held The spray gun is moved to realize the left and right, up and down adjustment of the spray gun position and the adjustment of the spray gun angle, but this manual adjustment method has the following defects: (1) It puts forward certain technical r...

Problems solved by technology

In order to achieve a comprehensive spraying on the surface of the workpiece, the workpiece and / or the spray gun need to be moved during the spraying process. In the prior art, since the spray gun generally does not have an automatic adjustment device, the nozzle of the spray gun generally cannot be rotated. Therefore, most of them rely on manual hand-held The spray gun is moved to realize the left and right, up and down adjustment of the spray gun position and the adjustment of the spray gun angle, but this manual adjustment method has the following defects: (1) It puts forward certain technical requirements for technicians, resulting in high labor costs and relying on technicians To a large extent

(2) Relying on technicians to manually adjust the angle of the spray gun, the workload is heavy, time-consuming, and the accuracy cannot be guaranteed

(3) Every time the painted workpiece is changed, technicians need to manually adjust the position and angle of the spray gun, which makes it difficult to remember the positions of different painted products, and there is no adjustment data reference

(4) The inaccuracy of manual adjustment can easily lead to low spray quality

A better way is to install an automatic spray gun adjustment device on the assembly line. The spray gun automatic adjustment device can automatically adjust the position and spraying angle of the spray gun under the control of the controller, but the control program of this automatic adjustment device is complicated and difficult to implement. , high cost, and prone to failure

In particular, when spraying workpieces with similar sizes, it is not necessary to frequently adjust the position of the spray gun, and only by rotating the spray angle of the spray gun can achieve better spraying effect. In this case, the spray gun automatic adjustment device is used for spraying It is obviously unwise; however, adopting a device for completely manually adjusting the position and angle of the spray gun will bring a lot of time and manpower waste, especially when adjusting the angle of the spray gun, repeated attempts are required, and adjustment errors are prone to occur; therefore, the research and development of a A device that can automatically adjust the spraying angle of the spray gun is suitable for scenes that do not need to frequently adjust the position of the spray gun, and it is necessary to solve the above-mentioned defects in the prior art
