DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within 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 includes a mechanical arm body 1 and further includes:

[0041] The welding smoke processing unit 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 be configured to have the welding smoke processing unit be symmetrically arranged in two 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 shell 3 with an inner processing chamber 4 inside, and the two ends of the outer shell 3 are connected and installed with a guide assembly 2. The inner processing chamber 4 is provided with a mounting cavity 411 for being inserted into the robot arm body 1.

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

[0043] Specifically, in order to filter out larger particulate impurities in the welding smoke and retain them in the dust filter chamber 5, this embodiment provides a smoke guide hole 421 for the inflow of welding smoke on the smoke guide plate 42, and a sieve hole that is connected to the adsorption filter chamber 401 is provided on the outer wall of the filter chamber 41, and the adsorption filter chamber 401 is provided with an external exhaust hole 402 for discharging welding smoke near the end of the connecting plate 43; a filter is installed in the dust filter chamber 5 and at the sieve hole on the outer wall of the filter chamber 41. Larger particulate impurities will enter the dust filter chamber 5 through the smoke guide hole 421 and be filtered by the filter, so that the large particulate impurities will be retained in the dust filter chamber 5, while tiny particles and smoke containing toxic gases will continue to enter the adsorption filter chamber 401. In this embodiment, the adsorption filter chamber 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 exhaust 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 will be clogged and the saturated adsorption effect of the activated carbon will decrease; and in this 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 the use cost is low, and the treatment effect is stable and reliable.

[0045] In order to strengthen the flow path of welding smoke, the present embodiment makes welding smoke 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 one-way 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 inhaled by 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 screen, 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 carry away the impurities retained in the adsorption filter cavity 401 and the dust filter cavity 5, restoring the welding smoke filtering and processing capacity of the device, and has strong recyclability.

[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 under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0048] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such 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 invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
