[0028] The base 1 has an adapter groove 17 inside. A first spring 18 is fixedly connected to the inner surface of the adapter groove 17. An inclined block 19 is fixedly connected to the right end of the first spring 18. A pin 20 is fixedly connected to the right surface of the inclined block 19.

[0029] Working principle: In use, the electrical grid to be welded is placed between two clamping plates 11. Then, the second motor 9 is started, driving the bidirectional lead screw 10 to move the clamping plates 11 on both sides toward each other, thereby clamping the electrical grid with the rubber pad 12. Then, the controller 29 controls the start of the first motor 3 and the cylinder 6. Under the action of the first motor 3, the lead screw 4, together with the slider 5, moves the welding head 7 to directly above the part of the grid to be welded. Then, the cylinder 6 is controlled to move the welding head 7 downward, thereby achieving the positioning welding of the electrical grid. Under the shielding effect of the filter glass plate 16, the strong welding light can be prevented from irritating the eyes of the workers, thereby improving the protection effect. When the filter glass plate 16 is not needed, the pressure block 22 is pressed down, driving the slide rod 21 to drive the roller 26 to roll along the inclined surface of the inclined block 19, thereby making the inclined block... 19 and the pin 20 move to the left, compressing the second spring 23 and the first spring 18, thereby disengaging the pin 20 from the interior of the socket 27 and releasing the restriction on the fixing plate 15. At this time, under the gravity of the filter glass plate 16, the filter glass plate 16 will move downward along the cavity 13 and be stored inside the first motor 3 with the cooperation of the fixing plate 15, thereby protecting the filter glass plate 16 and extending its service life. When the filter glass plate 16 needs to be used again, simply press the pressure block 22 again, insert your hand into the handle hole 28, and pull up the filter glass plate 16. When the socket 27 corresponds to the pin 20, release the pressure block 22. Under the restoring force of the first spring 18 and the second spring 23, the pin 20 will automatically insert into the socket 27, thereby limiting and fixing the position of the filter glass plate 16, which is simple and convenient.
