[0031] The application will be described in detail below with reference to the accompanying drawings and optional embodiments.

[0032] Figure 1 is a schematic view of a multi-station solder fume purification device according to an embodiment of the application, as Figure 1 The multi-station solder fume purification device 10 comprises a purification main body 100, a fume absorption main pipeline 200, at least one branch pipeline 300 and at least one soldering gun 400. One end of the fume absorption main pipeline 200 is connected to the air inlet 110 of the purification main body 100. One end of the branch pipeline 300 is connected to the fume absorption main pipeline 200. The other end of the branch pipeline 300 is connected to the soldering gun 400, and the air inlet 330 of the branch pipeline 300 faces the gun head of the soldering gun 400. The branch pipeline 300 is used to absorb the fume generated when the soldering gun 400 works, and the purification main body 100 is used to purify the fume.

[0033] For example, when performing soldering work, the purification main body 100 can be started manually to absorb fume, or the purification main body 100 can be started by fume detection, which is not limited herein.

[0034] Compared with the existing multi-station solder fume purification device 10, the application sets the fume absorption main pipeline 200 in cooperation with the branch pipeline 300. One branch pipeline 300 is connected to one soldering gun 400, and the air inlet 330 of the branch pipeline 300 faces the gun head of the soldering gun 400. In this way, when the soldering gun 400 is used, the fume generated by each soldering gun 400 will be directly sucked into the branch pipeline 300 by the air inlet 330, and then enter the purification main body 100 through the fume absorption main pipeline 200, and be purified by the purification main body 100. In this way, the operator will not inhale the fume, and the health of the operator will not be harmed.

[0035] And because the branch pipe 300 is directly connected with the soldering gun 400, and the suction port 330 of each branch pipe 300 is directed towards the gun head of the respective connected soldering gun 400, the distance between the suction port 330 and the gun head of the soldering gun 400 where the smoke is generated is shortened, so that the power of the multi-station soldering smoke purification device 10 can be greatly reduced, thereby saving energy and being more efficient and economical.

[0036] The multi-station soldering smoke purification device 10 further comprises a table body 510, a support horizontal rod 520 and a support vertical rod 530, both ends of the support vertical rod 530 are connected with the table body 510 and the support horizontal rod 520 respectively, the support horizontal rod 520 is arranged in parallel with the smoke absorption main pipe 200, the smoke absorption main pipe 200 is connected with the support horizontal rod 520, and the table body 510 is used for placing the soldering gun 400. By arranging the support horizontal rod 520 and the support vertical rod 530, the stability of the smoke absorption main pipe 200 can be ensured.

[0037] Figure 2 is a schematic view of a branch pipe according to an embodiment of the present application, in combination with Figure 2 As shown in the figure, the branch pipe 300 comprises a first sub-branch pipe portion 310 and a second sub-branch pipe portion 320, both ends of the first sub-branch pipe portion 310 are connected with the smoke absorption main pipe 200 and the second sub-branch pipe portion 320 respectively, one end of the second sub-branch pipe portion 320 away from the first sub-branch pipe portion 310 is a suction port 330, and the one end of the second sub-branch pipe portion 320 away from the first sub-branch pipe portion 310 is directed towards the gun head of the soldering gun 400; the first sub-branch pipe portion 310 is made of flexible material, and the second sub-branch pipe portion 320 is made of rigid material.

[0038] The first sub-branch pipe portion 310 is made of flexible material, so that the movement of the branch pipe 300 is more free, and the operator can also be more flexible when holding the soldering gun 400 for welding; the second sub-branch pipe portion 320 is made of rigid material, so that the suction port 330 is always directed towards the gun head of the soldering gun 400 without displacement, and it is more convenient for the operator to hold.

[0039] For example, the first sub-branch pipe portion 310 is a soft rubber pipe, and the second sub-branch pipe portion 320 is a metal pipe.

[0040] Exemplarily, the number of the branch pipes 300 includes eight, the number of the soldering guns 400 includes eight, and each of the soldering guns 400 is connected with one of the soldering guns 400 respectively. Thus, the purification efficiency can be improved, and one purification main body 100 is provided with eight branch pipes 300, and accordingly, the smoke on the eight soldering guns 400 can be absorbed simultaneously, so as to reduce the number of the purification main body 100 and the cost of the multi-station soldering smoke purification device 10.

[0041] Of course, the number of the branch pipes 300 can also include ten, the number of the soldering guns 400 includes ten, and each of the soldering guns 400 is connected with one of the soldering guns 400 respectively.

[0042] The number of the branch pipes 300 can also include twenty, the number of the soldering guns 400 includes twenty, and each of the soldering guns 400 is connected with one of the soldering guns 400 respectively; at this time, the number of the air inlets 110 of the purification main body 100 includes two, and the number of the smoke absorption main pipes 200 includes two, wherein ten branch pipes 300 are connected with one smoke absorption main pipe 200, and the other ten branch pipes 300 are connected with the other smoke absorption main pipe 200.

[0043] Each of the branch pipes 300 is provided with a switch valve 340, and the switch valve 340 is arranged at the end of the first sub-branch pipe part 310 close to the smoke absorption main pipe 200, and the switch valve 340 is used for controlling the on-off of the branch pipe 300.

[0044] Thus, when the soldering gun 400 on only one station is working, the switch valves 340 on the branch pipes 300 on the other stations can be kept in the closed state, so as to avoid the situation that the multi-station soldering smoke purification device 10 is damaged due to the foreign matters sucked into the branch pipes 300 on the other stations.

[0045] Moreover, after the switch valves 340 on the branch pipes 300 on the other stations which do not perform the soldering operation are closed, the air suction efficiency of the branch pipes 300 on the station which performs the soldering operation can be improved.

[0046] Figure 3 is a schematic view of a smoke absorption main pipe of an embodiment of the present application, like Figure 3As shown, the smoke absorption main pipeline 200 comprises a plurality of first sub-main pipeline portions 210 and a plurality of second sub-main pipeline portions 220, the plurality of first sub-main pipeline portions 210 and the plurality of second sub-main pipeline portions 220 are sequentially and spaced detachably connected, and the two ends of the second sub-main pipeline portion 220 are respectively sleeved on the outer walls of the left and right first sub-main pipeline portions 210; the first sub-branch pipeline portion 310 is connected with the second sub-main pipeline portion 220 away from the second sub-branch pipeline portion 320.

[0047] In short, through the sequential and spaced detachable connection of the plurality of first sub-main pipeline portions 210 and the plurality of second sub-main pipeline portions 220, the distance between the two branch pipelines 300 can be adjusted at will, for example, when it is needed to increase the distance between the two branch pipelines 300, longer first sub-main pipeline portions 210 can be connected between the second sub-main pipeline portions 220, so as to realize free adjustment.

[0048] And the number of stations can also be increased or decreased at will, for example, when it is needed to reduce the number of stations, i.e. to reduce the branch pipeline 300, the second sub-main pipeline portion 220 can be disassembled, and when it is needed to increase the number of stations, the second sub-main pipeline portion 220 can be sleeved at the tail end, so that the adjustment of the number of stations of the multi-station soldering fume purification device 10 is more flexible.
