Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a rotary spray gun device for spraying, a teaching handle and a spraying robot. Background Art

[0002] Spraying robots are increasingly being used in hardware, furniture, bathroom, engineering machinery and other applications. Some workpieces require spraying of internal cavities, such as electrical control cabinets, furniture cabinets and other cabinets that have internal cavities and their internal surfaces also need spraying. This application scenario requires the spray gun to be able to extend into the cavity, and the spray gun nozzle can point to the four inner sides: up, down, left and right.

[0003] At present, the robots used in the spraying industry are generally six-joint industrial robots. In order to spray the inner side, the spray gun needs to be clamped by the robot and pointed at each inner side. This will cause the robot to move in a large range, easily encounter singular points or interference, and the spraying effect is not good. There are also spraying robots that use hollow wrists, but the cost of the robots themselves is generally high. Utility Model Content

[0004] The utility model aims to provide a device suitable for spraying the inner cavity of a workpiece, so as to solve the problem of spraying the inner side of the workpiece.

[0005] To solve the above problems, the first aspect of an embodiment of the utility model provides a rotary spray gun device for spraying, comprising a gun body and a rotating mechanism; the gun body is provided with a nozzle, and there is an angle between the nozzle and the axis of the gun body, the gun body is fixed in the rotating mechanism, and the rotating mechanism is configured to drive the gun body to rotate around its own axis.

[0006] By setting an angle between the axis of the gun body and the nozzle, the gun body can be moved slightly, so that the nozzle points to one side of the workpiece to be sprayed, and then the spray gun is driven to rotate and move through the rotating mechanism to complete the spraying of several other internal sides. This setting can significantly reduce the movement amplitude of the spray gun during the spraying process, which is more conducive to completing the spraying work in a small space, and the spraying effect will also be significantly improved.

[0007] Preferably, the rotating mechanism includes a base, a fixing frame connected to the base and a first rotating component arranged in the fixing frame, wherein the first rotating component is connected to the gun body; a bearing is provided on the fixing frame, and the first rotating component is fixed to the inner ring of the bearing.

[0008] By such a configuration, the gun body is connected to the first rotating assembly, and the first rotating assembly rotates through the bearing on the fixed frame, thereby driving the gun body to rotate around its own axis. The fixed frame is connected to the base, and the spray gun device is easily installed on the operating device through the base.

[0009] Preferably, the rotating mechanism further comprises a rotating motor and a transmission assembly disposed in the fixing frame, and the rotating motor is connected to the first rotating assembly via the transmission assembly.

[0010] By adding a rotating motor in the fixed frame and connecting the rotating motor and the first rotating assembly using a transmission assembly, the first rotating assembly can be controlled to complete rotation by controlling the rotating motor, thereby facilitating the control of the rotation angle and timing of the spray gun driven by the first rotating assembly, while making the spray gun rotate at a uniform speed.

[0011] Preferably, the rotating mechanism further comprises a U-shaped shell, two side plates of the U-shaped shell are respectively fixed on the fixing frame, and the arc section of the U-shaped shell is arranged above the first rotating component and separates the first rotating component from the outside.

[0012] Through such an arrangement, the first rotating component rotates between the U-shaped shell and the fixed frame without contacting the outside world, thereby preventing the spraying material and external impurities from adhering to the first rotating component during the use of the spray gun device, reducing the cleaning and maintenance costs of the equipment. At the same time, the first rotating component is isolated from the outside world, which also improves safety during use.

[0013] Preferably, a quick-release guide rail is provided between the base and the fixed frame to enable quick disassembly and assembly between the base and the fixed frame; the quick-release guide rail includes a guide rail base fixed on the base, a slider provided on the fixed frame, and a limiting member that limits one end of the guide rail base and one end of the slider to each other.

[0014] Through such an arrangement, the fixed frame and the parts above it in the rotating mechanism can be quickly disassembled and assembled on the base, and the quick-release guide rail can be processed into a uniform size so that the spray gun device can be quickly installed and disassembled on equipment with different structures to complete the spraying work, thereby achieving versatility and improving processing efficiency.

[0015] Preferably, the limiting component includes a limiting cap and a limiting pin, the limiting cap is arranged inside the sliding block, and the limiting pin passes through the guide rail base and is connected to the limiting cap.

[0016] Through such an arrangement, the limit cap is set inside the slider, which is beneficial to saving the volume of the component. The slider and the guide rail base are linked by the cooperation of the limit cap and the limit pin, so that the relative position between the slider and the guide rail base is fixed, which is more conducive to the universal use of the spray gun device on other equipment.

[0018] Through such an arrangement, a pin is provided on the limit column of the limit latch, and the limit column with the pin part is extended into the limit cap, and the limit latch can be twisted, so that the limit cap limits the axial movement of the pin along the limit column, thereby realizing a reliable connection between the limit cap and the limit latch, and completing the rapid installation and disassembly of the slider and the guide rail base.

[0019] Preferably, the gun body and the first rotating assembly are detachably connected; the rotating mechanism also includes a second rotating assembly arranged on the gun body, when the gun body is fixed in the first rotating assembly, the second rotating assembly rotates together with the gun body, when the gun body and the first rotating assembly are separated, the second rotating assembly can drive the front part of the gun body and the nozzle to rotate.

[0020] Through such an arrangement, the gun body can be removed from the first rotating assembly, making the spray gun device suitable for more spraying conditions.

Through such a setting, in the teaching spraying process, the rotation angle of the spray gun device and the position of the mobile spray gun device can be adjusted according to the actual spraying effect to ensure the spraying quality in the teaching process. At the same time, the motion trajectory of the teaching handle can be recorded, and the angle and time of the rotation of the rotating mechanism can be controlled, so as to obtain a motion trajectory that can complete the spraying work on all sides of the workpiece, and can ensure the quality of the spraying.

[0023] Correspondingly, another aspect of an embodiment of the utility model provides a spraying robot, the spraying robot comprises the above-mentioned rotary spray gun device for spraying, and the rotary spray gun device for spraying is located at the protruding end of the spraying robot.
