DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0029] The filter assembly includes a filter box 410, which is installed on the welder 310. A partition 430, an air pump 440, a filter layer 450, a cotton yarn layer 460 and an activated carbon adsorption layer 470 are installed in the filter box 410. The partition 430 is located between the air pump 440 and the filter layer 450. The cotton yarn layer 460 and the activated carbon adsorption layer 470 are located at one end of the filter layer 450 away from the partition 430. An air outlet 480 is opened at one end of the filter box 410. One end of the air pump 440 passes through the partition 430. An air intake pipe 420 is installed at the other end of the air pump 440. The air intake pipe 420 passes through the filter box 410 and the welder 310.

[0030] During the welding process, the air pump 440 absorbs the welding point through the suction pipe 420, so that the harmful gases and impurities generated by the welding are absorbed into the filter box 410, and the harmful gases and impurities are filtered through the filter layer 450, the cotton yarn layer 460 and the activated carbon adsorption layer 470 in the filter box 410, and discharged through the air outlet 480, so that the harmful gases and impurities are not easy to float in the air, thereby preventing the staff from inhaling the harmful gases and impurities into the body, making the staff less likely to be harmed, and improving the safety of the staff. The filter layer 450 filters larger particles and impurities in the gas, and the cotton yarn layer 460 is used to filter impurities, particles and tiny pollutants in the gas. The activated carbon adsorption layer 470 can absorb harmful gases in the air.

[0031] The conveying assembly includes two groups of mounting frames 510, both of which are mounted on the base plate 110, and a conveyor belt 520 is installed between the two groups of mounting frames 510. A first motor 530 is installed on one group of the mounting frames 510, and the output end of the first motor 530 is transmission-connected to the conveyor belt 520.

[0032] The first motor 530 is used to drive the conveyor belt 520 to move, so that the conveyor belt 520 drives the display screen to move to the bottom of the welder 310, and moves the welded display screen, thereby reducing the workload of the staff in loading and unloading materials.

[0033] The clamping assembly includes two groups of moving grooves 610, which are respectively arranged on two groups of mounting frames 510, and the first moving plates 620 and clamping plates 660 are slidably connected in the two groups of moving grooves 610.

The clamping assembly also includes two groups of cylinders 630, which are respectively installed on the two groups of mounting frames 510, and the output ends of the two groups of cylinders 630 pass through the two groups of mounting frames 510, and the output ends of the two groups of cylinders 630 are respectively installed on the two groups of first moving plates 620.

[0034] When the display screen is clamped and fixed, the first movable plate 620 is driven to move by the cylinder 630, so that the first movable plate 620 drives the clamping plate 660 to move through the first spring 650, so that the two groups of clamping plates 660 clamp and fix the display screen, so that the display screen is not easy to move during welding. At the same time, the setting of the first spring 650 is used to clamp the clamping force of the clamping plate 660 on the display screen, so that the display screen is not easily subjected to excessive clamping force, thereby preventing the display screen from being damaged when fixed.

[0035] The position limiting assembly includes two groups of support frames 710, which are respectively mounted on two groups of mounting frames 510. The two groups of support frames 710 are rotatably connected with threaded rods 720, and the two groups of threaded rods 720 are threadedly connected with connecting blocks 740. The two groups of support frames 710 are both mounted with second motors 730, and the output ends of the two groups of second motors 730 are respectively connected to one end of the two groups of threaded rods 720.

When the display screen is limited, the second motor 730 drives the threaded rod 720 to rotate, so that the threaded rod 720 drives the second movable plate 750 to move vertically, so that the second movable plate 750 drives the limiting plate 780 to move through the second spring 770, so that the limiting plate 780 limits the display screen, so that the display screen is not easy to deviate, and the stability of the display screen welding is improved. At the same time, the second spring 770 is set to limit the position of the limiting plate 780 on the display screen, so that the display screen is not easy to be subjected to excessive pressure, so that the display screen is not easy to be damaged when fixed. The first guide rod 640 and the second guide rod 760 are set to guide the clamping plate 660 and the limiting plate 780 respectively, so that the clamping plate 660 and the limiting plate 780 remain stable during the movement, so that they are not easy to deviate.
