[0028] In this embodiment, the screw is placed inside the placement slot 12, and then the servo motor 27 is started, causing the servo motor 27 to drive the rotating shaft 28 to rotate. The rotating shaft 28 drives the disc 5 to rotate, and the disc 5 drives the circular block 6 to make a circular motion, thereby driving the rectangular plate 7 to move back and forth inside the horizontal slot 4, so that the rectangular plate 7 drives the connecting plate 10 to move back and forth inside the through slot 9. When the through slot 9 drives the horizontal plate 11 to move below the welding head 25, the cylinder 24 drives the welding head 25 to move downward to weld the screw. After the welding is completed, the servo motor 27 continues to drive the rotating shaft 28 to rotate, and then moves the horizontal plate 11 to move below the cooling fan 26. The cooling fan 26 then cools the welded screw by air cooling.

[0029] By placing the screw inside the placement slot 12 and then starting the servo motor 27, the rectangular plate 7 drives the connecting plate 10 to move back and forth inside the through slot 9. When the through slot 9 drives the horizontal plate 11 to move below the welding head 25, the welding head 25 moves downward to weld the screw. After the horizontal plate 11 moves below the cooling fan 26, the cooling fan 26 cools the welded screw. Compared with traditional automatic screw welding machines, this automatic screw welding machine effectively controls the temperature of the welding part by cooling it down in time after welding, preventing overheating and ensuring welding quality.

[0030] like Figures 1 to 7 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a connecting block 15 is fixedly installed at the bottom of the horizontal plate 11, a gear 16 is rotatably installed above the front end of the connecting block 15, a gear 17 is rotatably installed above the gear 16, a slider 13 is movably installed inside the placement groove 12, a rack 14 is fixedly installed above the slider 13, the rack 14 meshes with the gear 17, a connecting rod 22 is movably installed at the front end of the slider 13, and a fixing block 23 located inside the placement groove 12 is fixedly installed at the front end of the connecting rod 22.

[0031] In this embodiment, when the horizontal plate 11 moves inward, the toothed block 18 drives the gear 16 to rotate, which in turn drives the gear 17 to rotate. The gear 17 drives the rack 14 to move inward, which in turn drives the slider 13 to move inward. The slider 13 then drives the fixed block 23 to move inward to press the screw, causing the movable block 21 to retract into the interior of the circular groove 20 to press the return spring 31. This causes the return spring 31 to deform, thereby positioning and fixing the screw.

[0032] like Figure 1 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a cylinder 24 is fixedly installed on the top of the top cover 3, and the output end of the cylinder 24 extends to the bottom of the top cover 3 and a welding head 25 is fixedly installed thereon.

[0033] When the through slot 9 drives the horizontal plate 11 to move to the lower side of the welding head 25, the cylinder 24 drives the welding head 25 to move downward to butt weld the screw.

[0034] As shown in Figure 7 the same as the same concept of the above embodiment 1, the embodiment also proposes that the inside of the base 1 is fixedly installed with a servo motor 27, the upper side of the servo motor 27 is fixedly installed with a rotating shaft 28, and the rotating shaft 28 is fixedly connected to the lower side of the disc 5.

[0035] In this embodiment, the servo motor 27 is started to drive the rotating shaft 28 to rotate, the rotating shaft 28 drives the disc 5 to rotate, and the disc 5 drives the circular block 6 to move in a circular motion, thereby driving the rectangular plate 7 to move back and forth in the inside of the horizontal slot 4.

[0036] As shown in Figure 4 the same as the same concept of the above embodiment 1, the embodiment also proposes that the two sides of the horizontal slot 4 are provided with limiting grooves 29, and the lower side of the two ends of the rectangular plate 7 is fixedly installed with limiting rods 30 located in the limiting grooves 29.

[0037] In this embodiment, the back and forth movement of the rectangular plate 7 drives the limiting rods 30 to move back and forth in the inside of the limiting grooves 29, thereby limiting the rectangular plate 7.

[0038] As shown in Figures 1 to 3 the same as the same concept of the above embodiment 1, the embodiment also proposes that the two sides of the side plate 2 are provided with long grooves 19, and the long grooves 19 correspond to the rack 14.

[0039] In this embodiment, the horizontal plate 11 drives the rack 14 to move inward, so that the rack 14 moves inward in the inside of the long groove 19, thereby assisting the positioning of the long groove 19.

[0040] As shown in Figure 5 the same as the same concept of the above embodiment 1, the embodiment also proposes that the inside of the sliding block 13 is provided with a circular groove 20, the inside of the circular groove 20 is movably installed with a movable block 21, and the rear end of the connecting rod 22 extends to the inside of the circular groove 20 and is fixedly connected to the outside of the movable block 21.

[0042] As shown in Figures 1 to 3 the same as the same concept of the above embodiment 1, the embodiment also proposes that the inside of the side plate 2 is uniformly fixedly installed with a tooth block 18, and the tooth block 18 is engaged with the gear 16.

[0043] In this embodiment, the tooth block 18 drives the gear 16 to rotate, which in turn drives the gear 17 to rotate. The gear 17 then drives the rack 14 to move inward, and the rack 14 drives the slider 13 to move inward.

[0044] like Figures 1 to 7 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the welding head 25 corresponds to the center of the disk 5, and the cooling fan 26 corresponds to the rear end of the disk 5.

[0045] In this embodiment, after the disc 5 rotates and moves the block 6 to the center horizontal plane, the screw is welded. When the disc 5 rotates and moves the block 6 to the rear end, the screw is cooled.

[0046] like Figure 5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a reset spring 31 is elastically installed at the bottom of the circular groove 20, and the reset spring 31 is located inside the movable block 21.

[0047] In this embodiment, the slider 13 drives the fixed block 23 to move inward to squeeze the screw, causing the movable block 21 to contract into the inside of the circular groove 20 to squeeze the return spring 31, causing the return spring 31 to deform, thereby positioning and fixing the screw.

[0048] Working principle and usage process of this utility model:

[0049] The screw is placed inside the placement slot 12, and then the servo motor 27 is started, causing the servo motor 27 to drive the rotating shaft 28 to rotate. The rotating shaft 28 drives the disc 5 to rotate, and the disc 5 drives the circular block 6 to make a circular motion, thereby driving the rectangular plate 7 to move back and forth inside the horizontal slot 4, so that the rectangular plate 7 drives the connecting plate 10 to move back and forth inside the through slot 9. When the through slot 9 drives the horizontal plate 11 to move below the welding head 25, the cylinder 24 drives the welding head 25 to move downward to weld the screw. After the welding is completed, the servo motor 27 continues to drive the rotating shaft 28 to rotate, and then moves the horizontal plate 11 to move below the cooling fan 26. The cooling fan 26 then cools the welded screw.

[0050] When the horizontal plate 11 moves inward, the toothed block 18 drives the gear 16 to rotate, which in turn drives the gear 17 to rotate. The gear 17 drives the rack 14 to move inward, which in turn drives the slider 13 to move inward. This causes the slider 13 to drive the fixed block 23 to move inward and compress the screw. This causes the movable block 21 to retract into the inside of the circular groove 20 and compress the return spring 31, causing the return spring 31 to deform, thereby positioning and fixing the screw.
