[0033] Working principle: The shielding cover is placed in the unloading mechanism 102. After the device is started, the unloading mechanism 102 will send the shielding cover body 110 to the top of the servo turntable 103 and place it in the middle of the workbench 109. Then the servo turntable 103 will rotate and send the shielding cover body 110 to the loading mechanism 112. The loading mechanism 112 will start and place the spring 111 on the top of the shielding cover body 110. Then the servo turntable 103 will rotate again and send the shielding cover body 110 to the vertical plate 105. At this time, the slider 107 will drive the fixing mechanism 108 to slide along the slide rail 106 until the fixing mechanism 108 and the shielding cover body 110 come into contact. After the contact, the positioning module in the fixing mechanism 108 will position the shielding cover body 110. The position of the spring piece 111 is detected and the fixing mechanism 108 also fixes the shielding cover body 110 and the spring piece 111. When the position of the shielding cover body 110 is detected to meet the requirements, the welding mechanism 104 will start and weld the shielding cover body 110 and the spring piece 111. Finally, the welded shielding cover body 110 will be rotated to the unloading mechanism 102 by the servo turntable 103; after the workbench 109 is transferred to the loading mechanism 112 by the servo turntable 103, the loading mechanism 112 will send the spring piece 111 to the top of the shielding cover body 110.

After the sliding of 111 stops, it will contact with the surrounding vertical poles 2 and be fixed; lubricating oil is injected into the oil bag 32, and when the shielding cover body 110 is transported to the vertical plate 105, the slider 107 will start to slide along the slide rail 106, and the slider 107 will also drive the sponge 3 to slide together. During the sliding process, the sponge 3 will pass through the slide groove 33 and enter the inside of the oil bag 32, and then the sponge 3 will absorb the lubricating oil inside the oil bag 32. When the slider 107 is reset, it will drive the sponge 3 to slide along the slide rail 106, and the lubricating oil in the sponge 3 will flow out and reach the surface of the slide rail 106, thereby improving the smoothness of the surface of the slide rail 106; after the sponge 3 absorbs the lubricating oil from the oil bag 32, it will slide out of the slide groove 33, and the lubricating oil inside the sponge 3 will drip during the reset process.

After being squeezed, the arc-shaped sheet 5 will bend and transfer the pressure to the slide rod 52. The slide rod 52 will slide along the baffle 4 under the action of pressure and put the spring 53 in a stretched state. After being stretched, the spring 53 will release elastic potential energy and apply elastic force to the slide rod 52. The slide rod 52 will transfer the elastic force to the arc-shaped sheet 5 so that the arc-shaped sheet 5 squeezes the sponge 3. After the sponge 3 is squeezed, the lubricating oil inside will flow out;When the welding mechanism 104 welds the shielding cover body 110, a large amount of harmful gas will be generated, and these harmful gases will enter the interior of the guide plate 63 and flow out along the guide plate 63; when the equipment welds the shielding cover body 110, the harmful gas generated will flow along the guide plate 63, and when the gas flows, it will come into contact with the filter pad 7 and be filtered by the filter pad 7, thereby reducing the harmful components and particulate matter in the gas. ;
