[0036] Embodiment:

[0037] Such as Figure 1 , 2As shown in the figure, the utility model provides a cleaning space purification device for being installed on a robotic arm 101 for use. A laser cleaning head 102 is arranged at the end of the robotic arm 101. The device includes a mounting bracket 201 arranged on the robotic arm 101. A negative pressure pump 202 is arranged on the mounting bracket 201. A filtering mechanism is arranged at the input end of the negative pressure pump 202. The filtering mechanism includes an air purifier 203 arranged at the input end of the negative pressure pump 202. A communicating mounting shell 204 is arranged on the air purifier 203. One end of a suction pipe 401 is communicated with the mounting shell 204. A filter screen 301 is detachably arranged in the mounting shell 204. The other end of the suction pipe 401 is provided with a connecting seat 402. A suction head 403 is arranged on the connecting seat 402.

[0038] During use, the suction head 403 can be installed on the laser cleaning head 102, so that the suction head 403 moves along with the laser cleaning head 102. During the cleaning process, the negative pressure pump 202 can be controlled to start to suck the impurities separated from the substrate during the cleaning process into the mounting shell 204 through the suction head 403. The falling impurities are filtered by the filter screen 301 in the mounting shell 204, and the sucked air is filtered by the air purifier 203, thereby effectively reducing the content of harmful substances in the discharged air.

[0039] As Figure 2 、 3 shown in the figure, in this embodiment, a detachable mounting plate 205 is arranged on the mounting shell 204. A sliding groove 207 is formed on the mounting plate 205. Mounting ribs 302 are arranged at the end of the filter screen 301. The mounting ribs 302 are slidably clamped in the sliding groove 207. A collecting shell 206 is arranged on one side of the mounting plate 205. The opening of the collecting shell 206 abuts against the filter screen 301. During the filtering process, the impurities falling on the filter screen 301 can be collected by the collecting shell 206, which is convenient for cleaning the impurities. Moreover, the filter screen 301 can be detachably installed through the cooperation of the mounting ribs 302 and the sliding groove 207, which is convenient for timely cleaning and replacing the filter screen 301.

[0040] As Figure 1 、 2 shown in the figure, in this embodiment, a mounting mechanism for connecting with the connecting seat 402 is arranged on the laser cleaning head 102. Through the arrangement of the mounting mechanism, the suction head 403 can be driven to be located above the laser cleaning head 102 when the laser cleaning head 102 is in an inclined state. The mounting mechanism includes a bearing 501 sleeved on the laser cleaning head 102. A counterweight 502 is arranged on the bearing 501. Multiple groups of detachable counterweight columns 503 are arranged on the counterweight 502. A connecting frame 404 is arranged on the connecting seat 402. The connecting frame 404 is fixedly connected to the outside of the bearing 501.

[0041] The laser cleaning head 102 can move under the action of the robotic arm 101 for comprehensive cleaning. During the cleaning process, the suction head 403 is driven to move accordingly. By controlling the number of counterweight columns 503, the total weight of the counterweight columns 503 and the counterweight block 502 is made greater than the weight of the connecting seat 402 and the suction head 403, so that the suction head 403 can always be located above the laser cleaning head 102 during the cleaning process, avoiding interference with the movement of the laser cleaning head 102. Moreover, the opening direction of the inclined suction head 403 faces the extension line of the axis of the laser cleaning head 102 to improve the accuracy of impurity extraction.

[0042] Specific usage method and beneficial effects of the present utility model:

[0043] When the device is in use, the connecting seat 402 is installed on the laser cleaning head 102 through the installation mechanism. By controlling the start of the negative pressure pump 202, the impurities generated during the laser cleaning process are adsorbed through the suction head 403, and the extracted air is filtered through the filtering mechanism before being discharged to reduce the content of harmful substances in the discharged air. There is no need for manual cleaning of the impurities that fall during the laser cleaning process, effectively reducing the working intensity. Moreover, during the cleaning process, when the laser cleaning head 102 is tilted, the suction head 403 can be located above the laser cleaning head 102 under the action of the counterweight block 502 and the bearing 501, avoiding interference with the movement of the laser cleaning head 102 during the tilting process and improving the cleaning effect.

[0044] Obviously, the above embodiments are merely examples for clearly illustrating the present utility model and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
