Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automated welding, in particular to an energy-saving and environment-friendly welding robot. Background Art
[0002] As a common metal processing technology, welding is widely used in many fields such as manufacturing, construction, and shipbuilding. With the development of industrial automation, automatic welding machines have gradually replaced traditional manual welding and become one of the main equipment in the modern welding industry.
[0003] It is found in actual use that the existing welding robots have the following shortcomings:
[0004] During the welding process, high-temperature smoke is generated, accompanied by a large amount of harmful gases, which pollutes the environment. Long-term accumulation will also affect human health. Existing welding devices often do not have effective waste gas treatment measures, resulting in serious waste gas pollution and affecting the atmospheric environment.
[0005] In addition, since there is a large amount of gas in the weld, such as air and water vapor, these gases are directly welded by the welder without pretreatment before welding, and are trapped in the weld, forming pores, which will reduce the sealing, strength and toughness of the joint. The weld needs to be preheated, which increases the extra energy consumption of welding. However, the high-temperature fume is not utilized during the welding process, resulting in a large amount of energy waste in the welding process, affecting the energy utilization rate;
[0006] Therefore, the present application provides an energy-saving and environment-friendly welding robot to meet the needs. Utility Model Content
[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes an energy-saving and environment-friendly welding robot.
[0008] The technical problem to be solved by the utility model is to provide an energy-saving and environment-friendly welding robot to solve the problems of the existing energy-saving and environment-friendly welding robots.
[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0010] An energy-saving and environment-friendly welding robot comprises: a welding displacement working module, a frame, an electric welder, a mechanical arm, a fixed frame, a welding gun, a dust cover, an induced draft fan, an exhaust pipe, an electric telescopic rod, a heating seat, an air supply pipe, a rotating cylinder, a filter screen, a superheater and an exhaust fan, wherein the frame is installed on the side of the welding displacement working module, the electric welder is installed at the inner lower end of the frame, the mechanical arm is installed at the front end of the welding displacement working module, the fixed frame is installed at the front end of the mechanical arm, and the welding gun is installed on the internal joint of the fixed frame;
[0011] A dust cover is installed on the upper end of the fixed frame, an induced draft fan is installed at the inner upper end of the dust cover, an exhaust pipe is externally connected to the top of the dust cover, an electric telescopic rod is installed at the bottom of the fixed frame, a heating seat is installed on the output shaft of the electric telescopic rod, an air supply pipe is installed on the upper end of the heating seat, a rotating cylinder is installed at the inner upper end of the frame, a filter is installed at the inner upper end of the rotating cylinder, a superheater is installed in the middle of the rotating cylinder, and an exhaust fan is installed at the inner lower end of the rotating cylinder.
[0012] Preferably, the dust cover is in a trapezoidal shape, and extends to the front end of the fixing frame.
[0013] Preferably, the dust cover is located directly above the welding gun, and the dust cover covers the outer end of the welding gun, and the air outlet of the induced draft fan faces the welding gun.
[0014] Preferably, the exhaust pipe at the top of the dust cover is connected to the air outlet of the induced draft fan, and the other end of the exhaust pipe extends outward to the top of the rotating cylinder and is connected to the rotating cylinder.
[0015] Preferably, two groups of superheaters are provided, and the two groups of superheaters are located on the left and right sides of the interior of the central rotating drum in a mirror-symmetrical manner.
[0016] Preferably, the superheater is a screen-type superheater, and the superheater is arranged in a stepped manner, and the interval between two groups of superheaters gradually decreases.
[0017] Preferably, the air suction port of the exhaust fan is located at the bottom of the superheater, and the other end of the air supply pipe extends outward to the bottom of the rotating cylinder and is connected to the exhaust port of the exhaust fan.
[0018] Preferably, the heating seat is rectangular in shape, is made of metal copper, and is hollow inside.
[0019] Compared with the prior art, the utility model has at least the following beneficial effects:
[0020] 1. During welding with a welding torch, the dust cover can cover the welding torch, so that the smoke drifting upwards during welding gathers inside the dust cover. The induced draft fan inside the dust cover directly above the welding torch can attract the high-temperature smoke generated during welding. The high-temperature smoke attracted by the induced draft fan is discharged into the rotating cylinder through the exhaust pipe, capturing the smoke and harmful gases generated during welding, which can effectively dilute the harmful gases, reduce the concentration of harmful gases in the air, reduce the harm of welding to the environment and health, and make welding more environmentally friendly;
[0021] 2. When the high-temperature flue gas attracted by the induced draft fan is discharged into the rotating drum through the exhaust pipe, the dust in the flue gas is filtered through the filter screen in the rotating drum, and part of the convection heat can be absorbed by the superheater. After passing through the stepped superheater, the hot air can gradually gather to the middle for heating, effectively heating the temperature of the high-temperature flue gas. The high-temperature flue gas heated by the superheater is discharged from the rotating drum through the exhaust fan, and discharged into the heating seat through the air supply pipe. The heating seat made of metallic copper material is heated after the heated high-temperature flue gas is continuously introduced into the interior. The heating seat is driven to move by the electric telescopic rod. The heating seat heated by the high-temperature flue gas is attached to the welding position for heating, and the material to be welded is preheated. Then the welding gun is operated for welding to eliminate the gas in the weld. The waste heat of the high-temperature flue gas generated during the welding process can be recycled and utilized, thereby reducing the energy consumption during welding.

[0032] In this embodiment, the dust cover 7 is trapezoidal in shape and extends to the front end of the fixing frame 5. When welding is performed using the welding gun 6, the dust cover 7 can cover the welding gun 6, so that the smoke that floats upward during welding gathers into the dust cover 7.
