Description

Technical Field

[0001] This utility model relates to the field of paint protection technology, specifically a protective mechanism for a robot paint spraying control device. Background Technology

[0002] Spray painting is a method of applying paint to the surface of an object by using a spray gun to disperse the paint into uniform and fine droplets with air pressure.

[0003] In industrialized production, using robots for painting is more efficient. Inside the paint shop, a robotic arm holds a spray gun to perform the painting operation. During the painting process, the robotic arm holds the spray gun and sprays the paint. The mist of paint will disperse in the painted area. Because there are many wires connected to the robotic arm, a small amount of paint mist is not a problem. However, over time, too much paint mist will cause poor connections and affect the use of the equipment.

[0004] In view of this, we propose a protective mechanism for a robot painting control device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides two embodiments.

[0027] Example 1

[0028] Please see Figures 1 to 4 A protective mechanism for a robot painting control device includes a mounting bracket 100 disposed at the gripping end of a robot arm. Multiple mounting brackets 100 are arranged in a circular array at the gripping end of the robot arm. The mounting brackets 100 are distributed on the outer periphery of the outer shell at the gripping end of the robot arm. The mounting bracket 100 has a slot 101, and an air duct 200 is inserted into the slot 101. The air duct 200 is arc-shaped and adapted to the slot 101. The front end of the air duct 200 extends out of the slot 101 to provide a force-bearing position for the operator to handle. Multiple air holes 201 are opened at the front end of the air duct 200. A connector 700 is provided at the rear end of the air duct 200. The connector 700 passes through a through hole 102 opened on the mounting bracket 100 and extends out of the slot 101. The connector 700 is connected to a connecting pipe 300. The connecting pipe 300 is a flexible hose and is connected to an external fan. The inner cavity of the connecting pipe 300 is connected to the inner cavity of the air duct 200. When the external fan is working, the gas flows in the connecting pipe 300, and the negative pressure is generated in the cavity of the air duct 200, thus forming a suction force at the air hole 201 towards the cavity of the air duct 200. The paint mist generated when the spray gun held by the robotic arm sprays can be sucked into the air duct 200 and discharged along the connecting pipe 300.

[0029] This utility model, by setting up an installation frame 100, an air duct 200 and a connecting pipe 300, has the advantage that paint mist can be sucked into the air duct 200 and discharged along the connecting pipe 300, reducing the amount of mist adhering to the wiring end of the robotic arm clamping end. It solves the problem that excessive paint mist adhering to the wiring end of the robotic arm clamping end causes poor connection and affects the use.

[0030] The fastening structure 800 includes a threaded sleeve 801 and a screw 802. The threaded sleeve 801 is fixedly mounted on the outer periphery of the mounting bracket 100. The screw 802 is threadedly connected to the threaded sleeve 801. One end of the screw 802 abuts against the air duct 200, and the other end of the screw 802 is fixedly provided with a handle 803. When the operator rotates the handle 803, the screw 802 moves along the threaded sleeve 801 towards the slot 101 until one end of the screw 802 abuts against the air duct 200, fixing the air duct 200 in the slot 101. When replacing the air duct 200, the handle 803 is rotated in the opposite direction, and the screw 802 moves in the opposite direction along the threaded sleeve 801. One end of the screw 802 no longer abuts against the air duct 200, and the air duct 200 can be pulled out from the slot 101.

[0031] This utility model, by setting a threaded sleeve 801, a screw 802 and a rotating handle 803, has the advantages of fixing the air duct 200 while also facilitating the disassembly and processing of the air duct 200.

[0032] Example 2

[0033] Please see Figure 1 A protective mechanism for a robot painting control device includes a connecting ring 400 mounted on the cylindrical arm of the robot. A mounting plate 500 is fixedly mounted on the outer periphery of the connecting ring 400. An electric push rod 600 is fixedly mounted on the mounting plate 500. The electric push rod 600 can be selected and used by technicians according to actual conditions. The traveling end of the electric push rod 600 is fixedly connected to a mounting frame 100. The position of the mounting frame 100 at the gripping end of the robot arm can be adjusted by the electric push rod 600, thereby adjusting the position of the air duct 200 and allowing for adaptive movement of the connecting pipe 300.

[0034] This utility model, by setting a connecting ring 400, a mounting plate 500, and an electric push rod 600, has the advantages of adjusting the position of the air duct 200 at the gripping end of the robotic arm and removing paint mist from multiple positions.

[0035] Working principle: The connecting ring 400 is set on the cylindrical part of the robot arm, and the connecting pipe 300 is connected to an external fan. During painting, the external fan works, the gas flows in the connecting pipe 300, and the inner cavity of the air duct 200 is generated with negative pressure, thereby forming a suction force at the air hole 201 towards the inner cavity of the air duct 200. The paint mist generated by the spray gun held by the robot arm can be sucked into the air duct 200 and discharged along the connecting pipe 300. The electric push rod 600 adjusts the position of the mounting bracket 100 at the gripping end of the robot arm, thereby adjusting the position of the air duct 200. The connecting pipe 300 moves adaptively to discharge paint mist from multiple positions.
