[0002] Spray painting is one of the most important steps in the later stage of product production, which can improve the wear resistance and corrosion resistance of the product. However, in the existing technology, if manual spraying is used, the efficiency is low, and the uniformity of spraying mainly depends on personal experience, which is prone to uneven spraying; in addition, whether it is automatic spraying or manual spraying, a large amount of paint mist will be generated, which will escape into the air, causing waste of paint liquid, affecting the health of operators, and causing environmental pollution. [Utility Model Content]

[0003] The utility model provides an automatic spraying device to solve the above technical problems.

[0004] The utility model provides an automatic spraying equipment, the technical solution is:

[0006] Furthermore, an automatic paint supply system is arranged at the rear side of the leveling chamber and between the first spray paint room and the second spray paint room, the main agent supply box is arranged close to the second spray paint room, and the curing agent box and the cleaning agent box are arranged front and back and are arranged close to the first spray paint room.

[0007] Furthermore, the conveying mechanism is located at the top of the paint spraying room, and the conveying mechanism includes a hanger, and the hanger includes a crossbeam, a hook and a connecting rod. The crossbeam is provided with two symmetrical connecting holes, and chains are installed in the connecting holes. The bottom end of the chain is connected to the hook, and the hook is used to be hoisted on the lifting ear of the workpiece to be painted. A connecting rod is fixedly connected to the middle of the crossbeam, and the top of the connecting rod is connected to the rotating drive mechanism.

[0008] Furthermore, the control cabinet is provided with two paint spraying robots for respectively controlling the first paint spraying room and the second paint spraying room. The control cabinet is arranged in front of the leveling room and between the first paint spraying room and the second paint spraying room.

[0009] Furthermore, both the paint spraying outlet and the paint spraying inlet adopt pneumatic doors.

[0010] Furthermore, the rotary drive mechanism adopts a rotary motor.

[0011] Furthermore, in the paint spraying room, a stopper is provided on the left side of the paint spraying station, and in the leveling room, a stopper is provided on the left side of the static station.

[0012] Furthermore, in the leveling chamber, two static workstations are provided and arranged side by side on the left and right.

[0013] Furthermore, there is only one stopper in the leveling chamber, which is arranged on the left side of the static station on the left side.

[0014] The beneficial effects are:

[0015] (1) The use of a paint spraying robot has higher spraying efficiency and is easy to set spraying parameters, which helps to spray paint evenly. The robot arm is used for swinging spraying. The robot arm sprays paint evenly by swinging in multiple directions, up and down, left and right, to avoid excessive paint spraying on the surface of the workpiece, leaving traces of paint liquid flowing down, and to avoid insufficient paint spraying or no paint spraying on the surface of the workpiece, which makes the workpiece prone to wear and corrosion.

[0016] (2) A paint mist collecting box and a paint mist filter are set up to collect and filter the sprayed paint mist during painting to prevent excess paint mist that is not attached to the workpiece from escaping to the outside. At the same time, the paint mist inside the paint mist collecting box and the paint mist filter can be recovered to avoid wasting paint liquid.

[0017] (3) By setting up two spray booths, painting can be carried out simultaneously in the two spray booths, which effectively improves the painting efficiency of the workpiece.

[0018] (4) A leveling room is arranged between the two spray booths. The workpieces that have completed the first spraying are transported to the leveling room by the conveying mechanism for static placement, and then transported to the spray booth for the second spraying. This can ensure the paint thickness of the workpieces and ensure that the paint is more uniform.

[0019] (5) After the workpiece is finished painting in the first spray room, it enters the leveling room to stand still. While the workpiece is standing still, the next workpiece can be painted in the first spray room at the same time. After the next workpiece is finished painting, the previous workpiece is transported to the second spray room for painting, which can save time and improve the painting efficiency.

[0020] (6) Placing the rotating drive mechanism and the conveying mechanism at the top of the paint spraying room can effectively prevent the paint mist from falling into the drive mechanism or the conveying mechanism, prevent the paint mist from being deposited in the mechanical structure of the rotating drive mechanism and the conveying mechanism, and prevent the mechanical structure from being stuck or corroded.
