The welding atmosphere is not conducive to the operation of workers. Therefore, to solve this problem, it is necessary to consider how to reduce the concentration of welding smoke in the working atmosphere; the existing publication number CN109249157A is an environmentally friendly welding robot, including a base and a remote controller, a protective cover is welded and fixed above the base, a welding chamber is installed inside the protective cover, a dust suction device is installed on the side of the welding chamber close to the base, and a smoke exhaust duct is installed on the top left side of the protective cover; however, the above patent can filter the smoke during the dust suction process, but it cannot achieve continuous operation, and the filter structure needs to be cleaned and replaced regularly, the internal dust suction device needs to be replaced regularly, and the recyclability is poor.

[0004] In summary, we consider designing a welding robot arm that can absorb and process welding smoke, and has long-term and recyclable processing capabilities to reduce the frequency of replacing internal parts; in view of this, we propose an environmentally friendly mechanical welding arm.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0039] See also Figure 1-10 The present invention describes the above technical solution in detail through the following embodiments:

[0040] An environmentally friendly mechanical welding arm comprises a mechanical arm body 1, and further comprises:

[0041] The welding smoke treatment part of this embodiment can be detachably mounted on the main shaft arm 101 of the robot body 1. When installing the main shaft arm 101, a plug-in installation method is adopted. It should be noted that other embodiments can also set the welding smoke treatment part into two symmetrically arranged parts, and form the same structural features as this embodiment by clamping and installing; refer to Figure 2 , Figure 3 The structure shown specifically includes an outer casing 3 with an inner processing chamber 4 inside, and flow guide components 2 are installed at both ends of the outer casing 3. The inner processing chamber 4 is provided with a mounting cavity 411 for being inserted into the robot arm body 1.

[0042] It should be noted that, see Figure 5-Figure 8 As shown in the structure, the outer jacket bin 3 of this embodiment adopts an olive-shaped structure with small cross-sections at both ends and a large cross-section in the middle; the inner processing bin 4 includes a filter bin 41 with smoke guide plates 42 and connecting plates 43 installed at both ends, and the filter bin 41 is coaxially installed inside the outer jacket bin 3 through the smoke guide plates 42 and the connecting plates 43; a dust filter cavity 5 is provided between the outer jacket bin 3 and the inner processing bin 4, and an adsorption filter cavity 401 which is connected to the dust filter cavity 5 is provided on the inner processing bin 4.

[0043] Specifically, in order to filter out larger particle impurities in the welding smoke and retain them in the dust filter cavity 5, in this embodiment, a smoke guide hole 421 for the welding smoke to flow in is provided on the smoke guide plate 42, a sieve hole connected to the adsorption filter cavity 401 is provided on the outer wall of the filter bin 41, and an external discharge through hole 402 for discharging the welding smoke is provided at one end of the adsorption filter cavity 401 close to the connecting plate 43; a filter is installed in the dust filter cavity 5 and at the sieve hole on the outer wall of the filter bin 41, and larger particle impurities will enter the dust filter cavity 5 through the smoke guide hole 421, and through the filtering effect of the filter, the large particle impurities will be screened and retained in the dust filter cavity 5, while tiny particles and smoke containing toxic gases will continue to enter the adsorption filter cavity 401. In this embodiment, the adsorption filter cavity 401 is filled with activated carbon, which adsorbs tiny solid particles and harmful gases in the welding smoke and then completes the treatment and is discharged from the external discharge through hole 402; this process cycle can reduce welding smoke impurities in the working atmosphere and improve the working environment.

[0044] It is also worth explaining that both the filter and activated carbon treatment methods are physical means, which have saturation problems, that is, after long-term use, the filter is clogged and the saturated adsorption effect of the activated carbon decreases; and in the present application, the outer sleeve 3 is provided with a first guide tube 31 and a second guide tube 32, and the first guide tube 31 and the second guide tube 32 are used for external flushing water sources to clean the dust filter chamber 5 and the adsorption filter chamber 401. The device can screen or adsorb solid impurities, and through water washing, the solid impurities can be washed out without disassembling the device, which is conducive to obtaining long-term environmental protection treatment effects, and has low use costs and stable and reliable treatment effects.

[0045] In order to strengthen the flow path of welding smoke, the welding smoke can flow through the dust filter chamber 5 and the adsorption filter chamber 401 in sequence. The guide assembly 2 includes a guide sleeve 21 detachably mounted on the robot body 1, and a fan 22 is installed around the guide sleeve 21 to Figure 1 For example, the upper guide component 2 sucks air and the lower guide component 2 blows air to obtain welding smoke flowing in a unidirectional path.

[0046] The working principle of the environmentally friendly mechanical welding arm of this embodiment is as follows: the welding smoke generated by the mechanical arm body 1 during the welding process is sucked into the adjacent guide component 2, and the welding smoke will enter the dust filter cavity 5 from the smoke guide hole 421. First, the large particles of impurities are filtered out and retained in the dust filter cavity 5 by the filtering effect of the filter net, and the small particles of impurities and toxic gases entering the adsorption filter cavity 401 will be adsorbed by the activated carbon and then discharged. In this process, a large amount of dust particles are retained in the adsorption filter cavity 401 and the dust filter cavity 5; the device does not need to disassemble and replace the filter structure, but only flushes clean water into the interior through the first guide pipe 31 and the second guide pipe 32. In this process, the angle of the main shaft arm 101 is adjusted to facilitate the discharge of water. The water will take away the impurities retained in the adsorption filter cavity 401 and the dust filter cavity 5, thereby restoring the welding smoke filtering and processing capacity of the device, and the recyclability is strong.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
