One set of guide mechanisms 58 is used to guide the metal strip to be welded into the butt positioning mechanism 1, and the other set of guide mechanisms 58 is used to guide the welded metal strip out of the weld monitoring mechanism 7.

[0071] It is worth noting that the metal strip butt welding device with butt positioning function needs to be used in cooperation with a metal strip unwinding mechanism and a metal strip winding mechanism. Specifically, the metal strip unwinding mechanism is used to unwind the metal strip, the metal strip is positioned and welded by the butt positioning mechanism 1, and then the welded metal strip is monitored and marked by the weld monitoring mechanism 7, and finally the metal strip is wound by the metal strip winding mechanism. Since the metal strip unwinding mechanism and the metal strip winding mechanism are prior art, they are not described in detail in the present solution.

[0072] Specifically, referring to Figure 1 , Figure 2 and Figure 16 , in the embodiment, the guide mechanism 58 comprises a guide frame 59, a guide motor 60, a bidirectional screw 61 and a guide roller 62. The guide frame 59 is in an inverted U-shaped structure, and two sets of lifting grooves 63 are formed in the lower part of the guide frame 59. The bidirectional screw 61 is rotatably arranged in the lifting grooves 63, and the bidirectional screw 61 is provided with two sets of lifting grooves 63. The guide motor 60 is fixedly arranged at the upper end of the guide frame 59, and the guide motor 60 is provided with a synchronous pulley corresponding to the upper end of the bidirectional screw 61. The guide motor 60 and the synchronous pulley of the bidirectional screw 61 are provided with a fifth synchronous belt 64, which is driven by the guide motor 60 to synchronously rotate the two sets of bidirectional screws 61. The two ends of the bidirectional screw 61 are provided with two sets of threaded blocks 65 through threaded connection. The guide roller 62 is rotatably arranged between the oppositely arranged threaded blocks 65 of the two sets of bidirectional screws 61, and the guide roller 62 is provided with two sets of threaded blocks 65 corresponding to the threaded blocks 65. The two sets of guide rollers 62 are used to convey the metal strip.

[0073] The working principle of the metal strip butt welding device with butt positioning function is as follows:

[0074] (1) Start the guide motor 60 in the forward direction, and drive the two sets of bidirectional screws 61 to synchronously rotate under the action of the fifth synchronous belt 64. The bidirectional screw 61 drives the two sets of threaded blocks 65 to move towards each other, and the threaded blocks 65 drive the two sets of guide rollers 62 to move towards each other, so that the distance between the two sets of guide rollers 62 is adapted to the thickness of the metal strip to be welded;

[0075] (2) Start the two sets of position adjusting motors 41 in turn, and the position adjusting motors 41 drive the connected position adjusting shafts 42 to rotate. Under the driving of the rotating position adjusting shafts 42 and the guiding of the non-rotating position adjusting shafts 42, the driving plates 43 drive the butt joint positioning assemblies to adjust the position, so that the transverse distance between the strip positioning rollers 2 of the two butt joint positioning assemblies and the projection of the welding mechanism 40 is adapted to the width of the two metal sheets;

[0076] (3) The two metal strips to be spliced are passed between the two sets of guide rollers 62 of one set of guide mechanisms 58, and then passed between the two sets of guide rollers 62 of another set of guide mechanisms 58 through the protection box 39, the feed slot 56 and the discharge slot 57 of the monitoring box 8, and then wound. The lower surface of the metal strip is in contact with the upper surface of the lower roller 6, and the sides of the two metal strips to be spliced are in contact with the strip positioning rollers 2 of the two butt joint positioning assemblies respectively. The strip positioning rollers 2 guide and convey the conveyed metal strips;

[0077] (4) Fine-tune the guide mechanism 58 again so that the two sets of guide rollers 62 are in contact with the upper surface and the lower surface of the metal sheet respectively;

[0078] Start the height adjusting motor 12. Under the meshing action of the first driving bevel gear 13 and the first driven bevel gear 14, one set of nut barrels 15 is driven to rotate. Another set of nut barrels 15 is driven to rotate through the meshing of the positioning adjusting gear 21 and the conveying adjusting gear 22. Based on the diameter and tooth number difference of the positioning adjusting gear 21 and the conveying adjusting gear 22, the rotating speed of one set of nut barrels 15 is twice that of another set of nut barrels 15. Under the driving action of the nut barrel 15 and the threaded rod 16, and the guiding action of the guide cylinder 17 and the guide rod 18, the upper roller 5 and the strip positioning roller 2 ascend and descend in the same direction until the upper roller 5 is in contact with the upper surface of the metal strip;

[0079] During the ascending and descending process of the upper roller 5, the ascending and descending speed of the upper roller 5 is twice that of the strip positioning roller 2, so that the strip positioning roller 2 is always located between the upper roller 5 and the middle position. During the ascending and descending process of the upper roller 5 and the strip positioning roller 2, the first transmission gear 33 and the second transmission gear 37 are always in meshing with the power gear 28;

[0080] (5) Start the power motor 26. The power motor 26 drives the power shaft 27 connected thereto to rotate. Under the action of the fourth synchronous belt 38, two or more sets of power shafts 27 rotate synchronously. The power shaft 27 drives the power gear 28 to rotate;

[0081] The power shaft 27 drives the second driving bevel gear 29 to rotate, and drives the rotating shaft 20 of a group of lower rollers 6 to rotate under the meshing action of the second driving bevel gear 29 and the second driven bevel gear 30, and drives a plurality of groups of lower rollers 6 to synchronously rotate under the action of the second synchronous belt 24;

[0082] The power gear 28 meshes with the first transmission gear 33 to drive the first transmission shaft 32 to rotate, the first transmission shaft 32 drives the third driving bevel gear 34 to rotate, and drives the rotating shaft 20 of a group of upper rollers 5 to rotate under the meshing action of the third driving bevel gear 34 and the third driven bevel gear 35, and drives a plurality of groups of upper rollers 5 to synchronously rotate under the action of the first synchronous belt 23;

[0083] The power gear 28 meshes with the second transmission gear 37 to drive the second transmission shaft 36 to rotate, and drives the rotating shaft 20 of a group of strip positioning rollers 2 to rotate under the action of a group of third synchronous belts 25, and drives a plurality of groups of strip positioning rollers 2 to synchronously rotate under the action of the remaining third synchronous belts 25; the conveying of the upper rollers 5 and the lower rollers 6, and the positioning conveying effect of the strip positioning rollers 2 cooperate to realize the splicing and positioning of metal strips of different widths and thicknesses, and the welding of the splicing positions of the two metal strips is completed under the action of the welding mechanism 40;

[0084] (6) When the spliced metal strip passes through the monitoring box 8, the air blowing pump 44 blows air to the metal strip through the air blowing plate 45 and the air blowing hole 46. If there is a gap in the weld of the metal strip, the air flow passes through the weld gap and acts on the elastic air bag 9. The elastic air bag 9 expands and presses the switch 10. The switch 10 drives the transverse air cylinder 52 and the longitudinal air cylinder 53. The longitudinal air cylinder 53 drives the marking drill rod 54 to contact the surface of the metal strip. The transverse air cylinder 52 drives the mounting block 55 to move, and the mounting block 55 drives the marking drill rod 54 to move relative to the metal strip, and marks the surface of the metal strip;

[0085] (7) With the movement of the metal strip, the gap in the weld position moves away from between the air blowing plate 45 and the air bag, the metal strip is isolated from the air blowing assembly and the elastic air bag 9, and the air flow no longer acts on the elastic air bag 9. The elastic air bag 9 returns to its original state. At this time, the reset spring 49 drives the switch 10 to reset, the marking assembly stops marking and returns to its original position to wait for the next marking.
