[0032] A material strip cross-feeding and welding device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 The utility model embodiment of a material strip cross-feeding welding device includes a first feeding line 100 and a second feeding line 110. The first feeding line 100 is used to convey a first material strip 160 after stamping. The first material strip 160 is formed with a first hardware 150. The second feeding line 110 is used to convey a second material strip 180 after stamping. The second material strip 180 is formed with a second hardware 170. The structure of the first material strip 160 and the second material strip 180 is as shown in FIG. Figure 6 As shown, a welding area 120 is formed at the intersection of the first feeding line 100 and the second feeding line 110. The welding area 120 is provided with a welding mechanism and a punching mechanism. The welding mechanism is used to weld the first hardware 150 to the second hardware 170. The punching mechanism includes an upper mold 130, a lower mold 140, and a power part that drives the upper mold 130 or the lower mold 140 to rise and fall. The upper mold 130 and the lower mold 140 cut off the first hardware 150 from the first material strip 160 along the up and down direction.

[0034] It should be noted that the first feeding line 100 and the second feeding line 110 are respectively provided with a material shortage sensing device, which can detect whether the hardware on the material belt is missing.

[0035] In some embodiments of the present invention, the lower die 140 is provided with a punch 190 , and the lower die 140 and the upper die 130 are engaged, so that the punch 190 cuts off the first hardware 150 of the first material strip 160 .

[0036] Therefore, the punch 190 is disposed on the lower die 140 to avoid the punch 190 from overlapping with the welding direction of the welding mechanism, thereby reducing the difficulty of structural arrangement of the welding mechanism.

[0037] In some embodiments of the present invention, referring to Figure 3 The lower mold 140 is provided with two limit assemblies for limiting the second material belt 180 of the second hardware 170 in the up and down directions. The two limit assemblies are distributed along the conveying direction of the second feeding line 110, and a punch 190 is arranged between the two limit assemblies, so that the second material belt 180 of the second hardware 170 is conveyed over the punch 190 to avoid interference between the punch 190 and the second hardware 170 during the conveying process.

[0038] In some embodiments of the present invention, the limiting assembly includes two limiting bars 200 , which are arranged opposite to each other. A limiting groove 210 is arranged on the opposite side of the two limiting bars 200 , and the limiting groove 210 accommodates the second material strip 180 passing through, and the limiting groove 210 is higher than the punch 190 .

[0039] Therefore, on the one hand, the limiting groove 210 lifts the second material strip 180 so that the second material strip 180 is higher than the punch 190, thereby preventing the second hardware 170 from interfering with the punch 190 during transportation. On the other hand, the limiting groove 210 can also limit the second material strip 180 in the horizontal direction, so that the first hardware 150 and the second hardware 170 can be accurately welded.

[0040] In some embodiments of the present invention, referring to Figure 5 The upper mold 130 has an abutment plate 220 , and the abutment plate 220 is provided with a receiving groove 230 for accommodating the limiting component. When the mold is closed, the abutment plate 220 can press the first hardware 150 toward the punch 190 to separate the first hardware 150 from the first material strip 160 .

[0041] Therefore, by utilizing the accommodating groove 230 to avoid the limiting assembly, when the upper die 130 and the lower die 140 are pressed together, the abutment plate 220 presses the first hardware component 150 toward the punch 190 , and the punch 190 cuts the first hardware component 150 from the first material strip 160 .

[0042] In some embodiments of the utility model, the welding mechanism includes a main body 240 and a laser head 250 extending from the main body 240. The laser head 250 is located above the upper mold 130. The upper mold 130 is provided with a channel 260 running through the upper and lower parts. The energy output by the laser head 250 passes through the channel 260 to weld the first hardware 150 to the second hardware 170.

[0043] Therefore, after the laser head 250 welds the first hardware part and the second hardware part 170, the first material strip 160 and the second material strip 180 do not need to be moved or positioned again. The cutting process can be completed by pressing the upper mold 130 and the lower mold 140 together, which greatly improves the efficiency of loading and welding.

[0044] In some embodiments of the utility model, the welding mechanism also includes a column 270 and a connecting frame 280 arranged on the column 270. The column 270 is located on the side of the laser head 250 away from the main body 240. The connecting frame 280 is connected to the laser head 250. Thus, the column 270 and the connecting frame 280 are used to support the laser, thereby improving the strength of the laser head 250, reducing the vibration generated during mold closing, and reducing the deformation and bending of the laser head 250.

[0045] In some embodiments of the present invention, the power member is a first cylinder 290 , which is located below the lower mold 140 . The lower mold 140 is provided with a through hole, and a piston rod of the first cylinder 290 passes through the through hole and is connected to the upper mold 130 .

[0046] Thus, it is avoided that the power component is arranged above the upper mold 130, the space occupied by the upper mold 130 in the vertical direction is reduced, and the structural arrangement of the welding mechanism is facilitated.

[0047] In some embodiments of the present invention, referring to Figure 4 The first feeding line 100 includes a first material guide trough 300 for accommodating the first material belt 160 to pass through, a pin 310 for driving the first material belt 160 to move along the first material guide trough 300, and a moving component for driving the pin 310 to move. The first material belt 160 is provided with a through hole for accommodating the pin 310 to be inserted.

[0048] Specifically, the moving assembly includes a second cylinder 350 and a third cylinder 360. The second cylinder 350 can drive the pin 310 to move up and down, and the third cylinder 360 can drive the second cylinder 350 to move horizontally. Therefore, the pin 310 cooperates with the perforation to enable the pin 310 to transport the first material strip 160 in an orderly manner.

[0049] In some embodiments of the utility model, the second feeding line 110 includes a conveying assembly, which includes an upper roller 320, a lower roller 330, and a motor 340 that drives the upper roller 320 or the lower roller 330 to rotate. The upper roller 320 and the lower roller 330 clamp and convey the second material strip 180 after welding, so that the welding positions of the first hardware 150 and the second hardware 170 overlap, thereby achieving precise welding.

[0050] Therefore, this embodiment has the following effects:

[0051] 1. The utility model sets a first feeding line 100 and a second feeding line 110. The first feeding line 100 can convey the second material strip 180 for punching out the second hardware 170, and the second feeding line 110 can convey the second material strip 180 for punching out the second hardware 170. There is no need to adopt the traditional manual feeding method of bulk hardware one by one, and there is no need to adopt the feeding equipment to feed the bulk hardware one by one. The feeding and welding efficiency is greatly improved, the labor cost is reduced, the line welding is realized, and the number of times the material is handled is reduced.

[0052] 2. The utility model forms a welding area 120 at the intersection of the first feeding line 100 and the second feeding line 110, and feeds different material strips in a cross manner, so that two hardware parts intersect and are positioned, and a welding mechanism is used to weld the two hardware parts. After welding, one of the hardware parts is cut off, and the two different hardware parts are welded together and output along one material strip, thereby achieving manpower reduction, improved utilization, stable equipment, guaranteed processing quality, improved production capacity, and reduced production costs.
