[0055] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0056] Please see Figures 1 to 5 As shown, this embodiment provides a sheet welding positioning device after rolling, including a base 1, a material transfer mechanism 2, a plate end positioning mechanism 3, a weld positioning mechanism 4, a clamping mechanism 5, and an edge pressing mechanism 6, wherein:

[0057] A frame 11 is provided on the base 1. The rolled sheet to be welded is placed on the frame 11 with the opening seam of the sheet facing upward. A welding station is provided on the frame 11.

[0058] The material transfer mechanism 2 is mounted on the frame 11 and is used to drive the sheet material to the welding station.

[0059] The plate end positioning mechanism 3 is located at both ends of the welding station and is used for axial positioning of the sheet material.

[0060] The weld positioning mechanism 4 includes a reference plate 41, which is used to determine the target weld position of the sheet before welding.

[0061] The clamping mechanism 5 is located on both sides of the welding station. The clamping mechanism 5 is used to drive the two seam edges of the opening seam of the sheet to approach each other and abut against different sides of the reference sheet 41.

[0062] The edge pressing mechanism 6 is located on both sides of the welding station. The edge pressing mechanism 6 is used to press the two seam edges that abut against the reference piece 41 and leave the welding position so that the opening seam of the sheet remains closed.

[0063] This enables automatic feeding, positioning, weld seam determination, and seam alignment of the rolled sheet material for subsequent welding, reducing manual labor, increasing the automation level of the equipment, and improving processing efficiency and forming consistency.

[0064] Optionally, see details. Figure 3 The gantry 11 is provided with support frames 12 on both sides, and the weld positioning mechanism 4 also includes a tilting arm 42 and a first cylinder 43, wherein:

[0065] One end of the tilting arm 42 is mounted on a support frame 12 on one side, and the other end of the tilting arm 42 is provided with a vertical plate 44, and the reference piece 41 is mounted on the vertical plate 44.

[0066] The first cylinder 43 is mounted on the support frame 12. The output rod of the first cylinder 43 is connected to the vertical plate 44. The first cylinder 43 is used to drive the reference plate 41 to stand upright on the frame 11 or on the support frame 12 on one side.

[0067] Thus, the position of the reference plate 41 is switched by the flipping arm 42. When the reference plate 41 is upright on the frame 11, it is convenient to position the two seam edges of the sheet. When the reference plate 41 is close to the support frame 12, the reference plate 41 makes way for the welding gun and does not affect the welding action.

[0068] Furthermore, a positioning groove 18 is provided on the frame 11 corresponding to the vertical position of the reference piece 41 so that the reference piece 41 can be accurately placed in place, thereby ensuring the alignment accuracy of the two seam edges; the thickness of the reference piece 41 here is consistent with the size of the weld to be formed.

[0069] Optionally, see details. Figure 2 and Figure 4 The clamping mechanism 5 includes a second cylinder 51 and a third cylinder 52, wherein:

[0070] The second cylinder 51 is mounted on the support frame 12 on both sides and located on the two sides of the sheet. The output rod of the second cylinder 51 is provided with a side pressure plate 53. The second cylinder 51 on both sides is used to drive the two side pressure plates 53 to simultaneously press against or move away from the outer surface of the sheet.

[0071] The third cylinder 52 is mounted on the support frame 12 on both sides and located above both sides of the sheet. The output rod of the third cylinder 52 is provided with a clamping plate 54. The third cylinders 52 on both sides are used to drive the two clamping plates 54 to push or move away from the outer surface of the sheet synchronously. The clamping plate 54 is provided with a first roller 55 that rolls in contact with the sheet.

[0072] Thus, through the coordinated action of the side pressure plate 53 and the clamping plate 54, the end of the sheet near the seam edge gradually bends inward until the opening seam closes, simulating the action of artificially pre-formed sheet.

[0073] In addition, in actual situations, the position of the opening seam may not be centered. By moving one seam edge that is beyond the center position against the reference piece 41, the sheet can be moved adaptively in the circumferential direction, so that the other seam edge can eventually accurately abut against the reference piece 41.

[0074] Furthermore, a fourth cylinder 13 is provided on the base 1 and located below both sides of the sheet. A support plate 14 is provided on the fourth cylinder 13, and a second roller 15 is provided on the support plate 14 to make rolling contact with the sheet.

[0075] Thus, the vertical displacement of the sheet is compensated by the support plate 14 during the clamping process, and the sheet is reliably supported.

[0076] Optionally, see details. Figure 3 The pressing mechanism 6 includes a swing arm 61 and a fifth cylinder 62, wherein:

[0077] Several swing arms 61 are mounted on the support frames 12 on both sides and arranged along the seam. One end of the swing arm 61 is rotatably connected to the support frame 12, and the other end of the swing arm 61 is provided with a pressure block 63.

[0078] The fifth cylinder 62 is mounted on the support frame 12. The output rod of the fifth cylinder 62 is connected to the middle of the swing arm 61. The fifth cylinder 62 is used to drive the pressure block 63 to press the seam edge onto the frame 11 or release the seam edge.

[0079] Therefore, the swing arm 61 drives the pressure block 63 to press the seam edge, preventing the sheet from shifting and ensuring the quality of subsequent welding.

[0080] Optionally, the base 1 and the support frame 12 are respectively provided with guide frames 16 arranged around the outer ring of the sheet, and the guide frames 16 are provided with third rollers 17 that roll in contact with the sheet.

[0081] Thus, by limiting and guiding the outer side of the sheet material through the guide frame 16, the sheet material is ensured to move accurately axially to the welding station.

[0082] Optionally, see details. Figure 5 The plate end positioning mechanism 3 includes a first positioning rod 31 and a second positioning rod 32, wherein:

[0083] The first positioning rod 31 is installed on the frame 11 and located at the feeding end of the welding station; the second positioning rod 32 is installed on the frame 11 and located at the discharging end of the welding station.

[0084] The first positioning rod 31 is telescopic. The first positioning rod 31 is used to retract to avoid the sheet when the sheet enters the welding station, and to extend to limit one end of the sheet when the sheet touches the second positioning rod 32.

[0085] The second positioning rod 32 can approach or move away from the first positioning rod 31. The second positioning rod 32 is used to limit the other end of the sheet entering the welding station and push the sheet toward the first positioning rod 31.

[0086] Thus, the first positioning rod 31 and the second positioning rod 32 work together to ensure that the sheet is accurately positioned at the welding station so that the seam edge can be accurately pressed in the subsequent process; specifically, the second positioning rod 32 can be moved by a motor screw drive pair.

[0087] Furthermore, the plate-end positioning mechanism 3 also includes a first positioning plate 33 and a second positioning plate 34, wherein:

[0088] The first positioning plate 33 is installed on the base 1 and located at the feeding end of the welding station; the second positioning plate 34 is installed on the base 1 and located at the discharging end of the welding station.

[0089] The first positioning plate 33 can rotate. The first positioning plate 33 is used to retract inward to avoid the sheet when the sheet enters the welding station, and to open outward to limit one end of the sheet when the sheet touches the second positioning plate 34.

[0090] The second positioning plate 34 can approach or move away from the first positioning plate 33. The second positioning plate 34 is used to limit the other end of the sheet entering the welding station and push the sheet toward the first positioning plate 33.

[0091] The first positioning rod 31 and the second positioning rod 32 act on the upper edge of the end of the sheet, and the first positioning plate 33 and the second positioning plate 34 act on the lower edge of the end of the sheet.

[0092] Therefore, by cooperating with the first positioning plate 33 and the second positioning plate 34, the positional accuracy of the sheet is further ensured, the sheet tilting is avoided, and the positioning accuracy is guaranteed. Specifically, the first positioning plate 33 can be driven by a rotary cylinder, and the second positioning plate 34 can be moved by a motor screw transmission pair.

[0093] Optionally, see details. Figure 5 The material transfer mechanism 2 includes a moving frame 21, a conveying motor 22, and a sixth cylinder 23, wherein:

[0094] A linear guide rail is provided on the gantry 11 along the axial direction of the sheet, and the movable frame 21 is slidably mounted on the linear guide rail;

[0095] The conveyor motor 22 is mounted on the frame 11 and located at one end of the linear guide rail. A first pulley is provided on the output shaft of the conveyor motor 22, and a second pulley is provided on the frame 11 and located at the other end of the linear guide rail. A belt is provided between the first pulley and the second pulley, and one part of the belt is connected to the movable frame 21.

[0096] Several sixth cylinders 23 are mounted on the movable frame 21. Each sixth cylinder 23 is arranged in a ring in the vertical plane. Each sixth cylinder 23 has a push plate on its output rod. The sixth cylinder 23 is used to drive the push plate to alternately switch between the first position and the second position. When the push plate is in the first position, the push plate opens outward to limit the end face of the sheet. When the push plate is in the second position, the push plate retracts inward to avoid the sheet.

[0097] Thus, by the reciprocating movement of the push plate and its opening and closing actions, the sheets are pushed one by one to the welding station, realizing the automatic flow of the sheets so as to connect with the previous rolling process; the sixth cylinder 23 here is a rotary cylinder.

[0098] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
