[0019] The second embodiment is based on the first embodiment, please refer to Figures 4 to 5As shown, the positioning mechanism 2 includes a side plate 21. The bottom of the side plate 21 is fixedly connected to the top of the base 1, and the side plate 21 is symmetrically installed along the center of the axis of the base 1. The side plate 21 is located on both sides of the slide plate 31. A first cylinder 23 is fixedly installed at both ends of the non-opposing side of the side plate 21. The output end of the first cylinder 23 passes through the side plate 21 and extends to the other side. A side groove plate 22 is fixedly installed at the output end of the first cylinder 23. When the plate is placed on the top of the support mechanism 3, the first cylinder 23 is activated, causing the first cylinder 23 to drive the side groove plate 22 closer to the plate, so that the top plate 24 first contacts both sides of the plate, and then gradually moves. During the process, the contact pressure between the top plate 24 and the plate gradually increases. By applying pressure to both sides of the plate, the position of the plate is adjusted. At the same time, during the pressure application, the contact pressure between the top plate 24 and the plate is transmitted to the inner pad strip 25. Utilizing the deformation characteristics of the elastic material of the inner pad strip 25, the top plate 24 slides in the groove of the side slide plate 26. The side groove plate 22 has symmetrical grooves on the side away from the side plate 21, and the side slide plate 26 is slidably installed in the grooves of the side groove plate 22. The bottom of the side slide plate 26 has evenly distributed slots 28, and the side slide plate 26 slides and adapts to the protrusion of the slide block 32 through the slots 28.

[0020] A groove is formed at the center of the side slide plate 26 away from the side groove plate 22, and a top plate 24 is slidably installed in the groove of the side slide plate 26. The bottom of the top plate 24 is in contact with the top of the support plate 33, and an inner pad 25 is fixedly installed between the top plate 24 and the side slide plate 26. The inner pad 25 is made of elastic material. During the adjustment of the plate position, the pressure blocks 27 on both sides of the top plate 24 contact the plate. The inclined surface at the bottom of the pressure block 27 contacts the top edges of the plate, generating a downward pressure on the plate. The bottom of the slide plate 26 is closely attached to the top of the support mechanism 3. When the plates are joined together, the slide plate 26 slides and adapts to the protrusion of the slide block 32 through the slot 28 at the bottom of the slide plate 26. When the slide block 32 moves together with the plate, it drives the slide plate 26 to slide in the groove of the side plate 22, and moves together with the plate, so that the pressure block 27 always exerts downward pressure on the plate. The two ends of the opposite side of the slide plate 26 are fixedly installed with pressure blocks 27. The bottom of the pressure block 27 is a slope, and the slope slopes inward from top to bottom. The pressure block 27 is located on both sides of the top plate 24.

[0021] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 10As shown, the butt joint mechanism 4 comprises side upright plates 41 which are symmetrically arranged along the central position of the axis of the base 1, and a hollow groove plate 42 is fixedly arranged between the side upright plates 41, a hollow groove is formed in the top central position of the hollow groove plate 42, and a third air cylinder 44 is fixedly arranged on the non-opposing surface of the side upright plate 41, and the third air cylinder 44 is symmetrically arranged along the central position of the axis of the side upright plate 41, when the two plates are close to each other, by virtue of the feature that the top of the guide roller 45 is flush with the top of the supporting plate 33, when butt joint, the plate is guided and supported by the top of the guide roller 45, at the same time, by virtue of the rotary connection between the guide roller 45 and the fixed plate 43, when the plate is guided and butt joint, the frictional resistance between the plate is reduced, and the output end of the third air cylinder 44 penetrates through the side upright plate 41 and extends to the other side, and the output end of the third air cylinder 44 is fixedly arranged with the fixed plate 43.

[0022] The guide roller 45 is rotatably arranged on the top of the two sides of the non-opposing surface of the fixed plate 43, the top of the guide roller 45 is flush with the top of the supporting plate 33, the top of the non-opposing surface of the fixed plate 43 is fixedly arranged with an inclined groove block 46, the inclined groove block 46 is symmetrically arranged along the central position of the axis of the fixed plate 43, after the plate welding surfaces are contacted, the fixed plate 43 is driven by the third air cylinder 44 to be close to each other, so that the fixed plate 43 drives the inclined groove block 46 to be close to the plate while being close to each other, the plate is contacted by the inclined groove of the inclined groove block 46, so that the butt joint plate is at the same height under the limitation of the inclined groove block 46, at the same time, when butt joint, the fixed plate 43 is not in contact with the plate welding position by virtue of the lack of groove in the top central position of the fixed plate 43, an inclined groove is formed in the outer side of the inclined groove block 46, and a lack of groove is formed in the top central position of the fixed plate 43.

[0023] In use, the workers put the bridge plates required for butt joint welding into the top of the supporting mechanism 3 on the two sides respectively, then the plate on both sides is pressed by the positioning mechanism 2, so that the central position of the plate corresponds to the central position of the supporting mechanism 3, at the same time, the downward pressure is generated when the positioning mechanism 2 presses on both sides, so that the bottom of the plate is tightly attached to the supporting mechanism 3, then the supporting mechanism 3 drives the plates on both sides to be close to each other, the plate is guided by the butt joint mechanism 4, so that the plate welding position is attached to the corresponding position, then the motor 5 drives the screw rod 9 to rotate, by virtue of the threaded connection between the screw rod 9 and the sliding block 8, when the sliding block 8 slides in the gantry 6, the welding gun 7 moves along the plate butt joint position, and the welding process is performed.

[0024] In the support mechanism 3, when the plate is put in, the bottom of the plate contacts the top of the support plate 33 and the roller 36 on both sides, the contact area with the bottom of the plate is reduced by the arc surface of the roller 36, and the rotation connection between the roller 36 and the connecting rod 35 is matched, the frictional resistance of the plate when the position adjusting mechanism 2 presses the plate is reduced, when the center position of the plate corresponds to the center position of the sliding seat 32 under the adjustment of the positioning mechanism 2, the positioning mechanism 2 applies a downward pressure to the plate, so that the bottom of the plate is tightly attached to the top of the support plate 33, then the second cylinder 39 drives the sliding seat 32 to slide on the top of the sliding groove plate 31, so that the plates are close to each other, and the welding surfaces of the plates are butted under the guidance of the butt joint mechanism 4. When the plates contact each other, extrusion force is generated between the plates, and there is a tendency for the plates to slide relative to the support plate 33. At this time, the friction between the support plate 33 and the plate transmits the tendency to the support plate 33, so that the support plate 33 tends to slide in the inclined groove of the inclined groove plate 37. The inclination of the inclined groove causes the support plate 33 to tend to extrude the plate upward, increasing the friction between the plate and the support plate 33 and limiting the sliding of the plate.

[0025] In the positioning mechanism 2, when the plate is put on the top of the support mechanism 3, the first cylinder 23 is started, the first cylinder 23 drives the side groove plate 22 to approach the plate, and the material lifting plate 24 first contacts the two sides of the plate. In the process of gradually moving, the contact pressure between the material lifting plate 24 and the plate is gradually increased, the position of the plate is adjusted by pressing the two sides of the plate, and at the same time in the process of pressing, the contact pressure between the material lifting plate 24 and the plate is transmitted to the inner gasket 25. The deformation characteristics of the elastic material of the inner gasket 25 make the material lifting plate 24 slide at the plate groove of the side sliding plate 26. In the process of adjusting the position of the plate, the pressing blocks 27 on both sides of the material lifting plate 24 contact the plate, the inclined surface at the bottom of the pressing block 27 contacts the edge position on both sides of the top of the plate, generates a downward pressure on the plate, and makes the bottom of the plate tightly attached to the top of the support mechanism 3. At the same time, when the plates are butted, the clamping groove 28 at the bottom of the side sliding plate 26 and the protrusion of the sliding seat 32 slide and fit, the sliding seat 32 moves with the plate, the side sliding plate 26 slides in the strip groove of the side groove plate 22, the plate moves together, and the pressing blocks 27 always generate a downward pressure on the plate.

[0026] In the docking mechanism 4, when the two sides of the plate are close to each other, the top of the guide roller 45 is flush with the top of the support plate 33, and when the plates are docked, the top of the guide roller 45 guides and supports the plates, and at the same time, the rotation connection between the guide roller 45 and the fixed plate 43 reduces the frictional resistance between the guide roller 45 and the plates. At the same time, after the plates are in contact, the third cylinder 44 drives the fixed plate 43 to approach each other, so that the fixed plate 43 approaches the plate while driving the inclined chute block 46 to approach the plate, and the inclined chute block 46 contacts the plate to make the plates in the same height under the restriction of the inclined chute block 46. At the same time, the fixed plate 43 and the plate welding position do not contact.
