Description

Technical Field

[0001] The utility model relates to the field of low-carbon environmental protection, and in particular to an integrated welding robot device with a waste gas collection and treatment function. Background Art

[0002] As a common metal processing method, welding has been widely used in industrial production. With the advancement of science and technology, laser welding technology has gradually replaced traditional welding methods due to its advantages of high precision, high efficiency and high quality.

[0003] However, this also brings problems. A large amount of volatile organic compounds (VOCs) gases are generated during laser welding, which not only pollute the environment but also harm human health. At present, some welding robot equipment has been equipped with exhaust gas collection and treatment systems to collect and treat the exhaust gas generated during laser welding. However, these devices still have many problems in actual use. For example, the metal components in the exhaust gas are easy to adhere to the filter, causing the filter to be blocked, which in turn affects the normal treatment of the exhaust gas.

[0004] In addition, the existing waste gas collection and treatment system is usually large in size and complex in structure, which is not easy to integrate into the welding robot equipment, affecting the integrity and installation portability of the equipment. For example, Chinese patent CN215692437U, a controller welding waste gas treatment device that is easy to clean, discloses an independent waste gas treatment device for controller welding.

[0005] Therefore, how to achieve the integrity and convenience of integrated welding and exhaust gas treatment on welding robot equipment while preventing metal components from clogging the filter so that the exhaust gas treatment device can effectively collect and treat the VOCs gas generated during laser welding is an urgent problem to be solved in the current field. Utility Model Content

[0006] The utility model provides an integrated welding robot device with a waste gas collection and treatment function. The waste gas treatment device is integrated with the welding robot, and at the same time, the filter screen can be prevented from being blocked by metal components.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An integrated welding robot device with exhaust gas collection and treatment function, comprising a laser welder that can be moved to perform welding operations, a panel surrounding the laser welder to form a working chamber of the laser welder, a gas collecting hood arranged at the top of the panel to collect exhaust gas from welding operations, an exhaust gas treatment device arranged at the periphery of the rear side of the panel and treating the exhaust gas collected by the gas collecting hood, and a movable bracket arranged at the bottom of the laser welder to carry welded parts;

[0009] The exhaust gas treatment device includes a catalytic processor connected to the gas collecting hood through an air guide pipe, an exhaust pipe for discharging the catalytically treated gas, and an air curtain arranged at the rear end of the exhaust pipe as an air outlet;

[0010] The wind curtain is arranged on the left side of the enclosure and the exhaust direction is perpendicular to the moving-out direction of the movable bracket.

[0011] Furthermore, it also includes an exhaust gas pre-treatment device arranged at the front end of the air collecting hood, and the exhaust gas pre-treatment device includes an exhaust gas treatment chamber, an air duct connected to the exhaust gas treatment chamber and sucking in the welding operation exhaust gas of the laser welder, a magnetic metal adsorption net for metal adsorption of the exhaust gas sucked in by the air duct, and a dust bag arranged at the bottom of the exhaust gas treatment chamber and collecting the metal adsorbed by the metal adsorption net.

[0012] Furthermore, it also includes a self-cleaning filter assembly arranged between the metal adsorption net and the air collecting hood, and the self-cleaning filter assembly includes a filter and an ultrasonic vibrator that makes the filter vibrate and drops the adsorbed particles into the dust collecting bag.

[0013] Preferably, the metal adsorption net and the filter net of the self-cleaning filter net assembly are arranged obliquely facing the air duct.

[0014] Specifically, the catalytic processor includes a room-temperature catalytic treatment material and a fan that can adsorb and catalytically decompose exhaust gas generated by welding at room temperature.

[0015] Specifically, the laser welder includes a mechanical arm for performing mobile welding, and the air duct is fixed to the mechanical arm and moves synchronously with the mechanical arm.

[0016] Furthermore, the air curtain is a porous mesh structure that can prevent foreign matter from entering from the air outlet.

[0017] Compared with the prior art, the beneficial effects of this case are as follows:

[0018] The laser welding robot in welding operation is surrounded by a panel, and a gas collecting hood is set at the top of the panel to collect the exhaust gas, and the exhaust gas treatment device is also set on the rear periphery of the panel to treat the exhaust gas. At this time, the wind curtain of the panel and the exhaust gas treatment device forms a relatively closed airflow sealing space for the laser welding robot, thereby realizing the integrated design of exhaust gas treatment and welding robot. At the same time, a self-cleaning exhaust gas pre-processor is set at the front end of the gas collecting hood, which can pre-treat the exhaust gas for metals and particulate matter, and extend the service life of the catalytic processor.

[0023] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0024] Embodiment 1, as Figure 1 As shown, the welding robot equipment described in this case includes a movable laser welder 100 responsible for performing welding operations. The movement mode of the laser welder 100 can adopt the motion module commonly used in robot structures. In this case, it can move left and right or move left and right, front and back XY biaxially according to needs. It is a common technical means in the industry and will not be described in detail. A movable bracket 110 is provided at the bottom of the laser welder 100, which can move left and right to carry the welded parts.

[0025] A panel 200 is arranged around the laser welder 100 to form a relatively sealed working chamber for the laser welder 100. For the convenience of description, only the left and right side panels, the top panel, and the rear side panel are shown in the figure in this embodiment. In actual application, an openable front door may also be provided. For the convenience of description, the panel 200 is used for the following description.

[0026] Please refer to Figure 2 A gas collecting hood 300 for collecting exhaust gas from welding operation is arranged at the top of the enclosure 200. The gas collecting hood 300 is an inverted cone that gradually becomes larger toward the laser welder 100. The gas collecting hood 300 and the top plate of the enclosure 200 are connected to each other to prevent the exhaust gas from escaping. An exhaust gas treatment device for treating the exhaust gas collected by the gas collecting hood 300 is arranged at the rear end of the gas collecting hood 300. Specifically, the exhaust gas treatment device includes a catalytic processor 420 connected to the gas collecting hood 300 through an air duct 410.

[0027] The catalytic processor 420 includes room temperature catalytic treatment materials and a fan, wherein the fan is the power mechanism of the exhaust gas treatment device. Driven by the fan, the exhaust gas can be sucked from the working chamber formed by the enclosure 200, and introduced into the catalytic processor 420 through the gas collecting hood 300 and the air duct 410 for catalytic treatment. The room temperature catalytic material is an adsorption-catalytic composite material, which can adsorb and catalytically decompose the exhaust gas generated by welding at room temperature. Specifically, it includes OC-KF ozone oxidation catalyst, OC-FT5 ozone oxidation catalyst, and porous ceramic particles with transition metals, rare earths, precious metals, etc. as active components, which can catalytically degrade VOCs gas. The rear end of the catalytic treatment is the exhaust pipe 430, which is directly connected to the wind curtain 440 as the air outlet. Specifically, the wind curtain 440 is a porous mesh structure, which can prevent foreign matter from entering from the air outlet.

[0028] OC-KF ozone oxidation catalyst can catalytically decompose ozone (oxidation potential 2.07V) at room temperature or low temperature to produce strong oxidizing oxygen free radicals and hydroxyl free radicals (oxidation potential 2.69V or 2.80V), rapidly catalytically decompose ozone and catalytically oxidize VOCs into CO2 and H2O, thereby solving ozone secondary pollutants while improving mineralization rate and purification efficiency. The greater the amount of ozone, the better the VOCs treatment effect.

[0029] OC-FT5 ozone oxidation catalyst can catalytically decompose ozone (oxidation potential 2.07V) at room temperature or low temperature to produce strong oxidizing oxygen free radicals and hydroxyl free radicals (oxidation potential 2.69V or 2.80V), quickly catalytically decompose ozone and catalytically oxidize VOCs into CO2 and H2O, solving ozone secondary pollutants while improving mineralization rate and purification efficiency. The greater the amount of ozone, the better the VOCs treatment effect. Therefore, an ozone generator, such as an ultraviolet lamp, will be set at the front end of the catalyst module, which will produce a certain amount of ozone when irradiated to improve the VOCs treatment effect. There are many ways to produce ozone, which will not be described in detail in this case.

[0030] Preferably, the air curtain 440 is arranged on the left side of the enclosure 200 and the exhaust direction is perpendicular to the moving direction of the movable bracket 110. At this time, the enclosure and the air curtain of the exhaust gas treatment device form a relatively closed airflow sealing space for the laser welding robot to prevent the exhaust gas from leaking out, thereby realizing the integrated design of exhaust gas treatment and welding robot.

[0031] The exhaust gas treatment device needs to have a certain degree of rigidity and airtightness, good integrity, and a regular structure for easy assembly and fixation. Aluminum alloy materials are selected to make its shell, and the material is preferably made of 0.5mm thick aluminum alloy plate to ensure its light weight, strength and assembly flexibility. In order to make the shell have better strength, a certain amount of support skeleton is set inside the shell, which has sufficient strength and the ability to fix internal components, can meet the needs of installation and positioning of other parts and avoid internal vibration displacement. The skeleton can provide sufficient support capacity and small deformation.

[0032] Furthermore, the panel 421 of the catalytic processor 420 of the exhaust gas treatment device is a panel structure designed for quick disassembly, and the panel can be quickly disassembled and assembled through the quick-release buckle, and the internal filter module can be taken out and replaced. Also, because the filter module of the catalytic treatment is a consumable material and will cause loss, it is necessary to pre-treat the exhaust gas at the front end. However, this will cause the pre-treatment network to become clogged and increase wind resistance, affecting the filtering effect. In this regard, measures have also been taken in this case.

[0033] Example 2, please refer to Figure 3 and Figure 4 . For the sake of convenience, the description of the same parts as those in the first embodiment is omitted when describing the second embodiment. In this case, an exhaust gas pre-processor is provided at the front end of the gas collecting hood 300. The exhaust gas pre-processor includes an exhaust gas treatment chamber 510 as a cavity for pre-treating the exhaust gas, and the exhaust gas from the welding operation of the laser welder 100 is sucked into and guided into the exhaust gas treatment chamber 510 through an air duct 520 connected to the exhaust gas treatment chamber 510. Preferably, the air duct 520 is provided on the side of the exhaust gas treatment chamber 510.

[0034] A metal adsorption net 530 is provided in the exhaust gas treatment chamber 510 to adsorb metals from the exhaust gas sucked by the induced draft pipe 520. When the metal adsorption net 530 is powered on, the internal adsorption wire will generate a magnetic field to adsorb metal particles, causing them to naturally deposit and be collected when the machine is shut down. At the same time, a dust bag 540 is provided at the bottom of the exhaust gas treatment chamber 510. When the machine stops working, the metal adsorption net 530 is powered off and the magnetic field disappears, and the metal particles fall due to their own weight and are recovered in the dust bag 540.

[0035] At the same time, it also includes a self-cleaning filter assembly 550 disposed between the metal adsorption mesh 530 and the gas collecting hood 300 , and the self-cleaning filter assembly 550 is also disposed inside the exhaust gas treatment chamber 510 .

[0036] Specifically, the self-cleaning filter assembly 550 includes a filter and an ultrasonic vibrator that causes the filter to vibrate and drop the adsorbed particles into the dust bag 540. The filter can be a coarse filter, which is mainly used to filter other particles in the exhaust gas except metal particles before catalytic treatment. When the work stops, the vibration of the ultrasonic vibrator can cause the filter of the self-cleaning filter assembly 550 to vibrate, causing it to drop the adsorbed particles, and the dropped particles are recovered by the dust bag 540.

[0037] Preferably, the metal adsorption net 530 and the filter net of the self-cleaning filter net assembly 550 face the air duct and are arranged obliquely, which can increase the windward area and improve the filtering effect.

[0038] The laser welder 100 also includes a robot arm for performing mobile welding. The air duct 520 is fixed to the robot arm to achieve the effect of following the movement of the robot arm of the laser welder 100, and can accurately and timely collect the smoke and harmful exhaust gas generated by welding.

[0039] As mentioned above, this case protects an integrated welding robot equipment with exhaust gas treatment function. All technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
