[0030] Reference Figure 4 and Figure 5 The sheet metal part 310 is in the shape of a long strip and has a groove 311. The connecting piece is U-shaped, and the width of the connecting piece matches the width of the groove 311. The connecting piece includes a first connecting piece 321 and a second connecting piece 322. The first connecting piece 321 is welded at both ends of the groove 311, and the second connecting piece 322 is welded at any position between the two first connecting pieces 321. During assembly, the connecting pieces are embedded in both ends of the groove 311 and in the groove 311, and then welded together to form an assembly.

[0031] Reference Figure 1 and Figure 2, automatic welding equipment, including: a first positioning mechanism, arranged on, including a first positioning member, the first positioning member is provided with a positioning groove 112 along the first direction that cooperates with the sheet metal part 310; a second positioning mechanism, including two groups of positioning parts 212, the two groups of positioning parts 212 are arranged at both ends of the first positioning member along the first direction, the positioning part 212 includes a second positioning member and a first driving member, the first driving member drives the second positioning member to move along the first direction, and the second positioning member is used to position the first connecting member 321; a third positioning mechanism, including a third positioning member and a second driving member, the second driving member drives the third positioning member to move along the second direction, and the third positioning member is used to position the second connecting member 322; a welding mechanism, including a welding robot 300, used to weld the sheet metal part 310 and the connecting member together, the welding robot 300 is a prior art and will not be described in detail here; wherein, the first direction and the second direction are perpendicular to each other, and the first direction is located in the horizontal plane, and the second direction is located in the vertical plane.

[0032] Place the sheet metal 310 into the positioning groove 112, preliminarily position the sheet metal 310, and then place the connecting part to the corresponding position of the sheet metal 310. The first driving part drives the second positioning part to clamp the sheet metal 310 from both ends of the sheet metal 310. At the same time, the second positioning part positions the first connecting part 321, and then the third positioning part is driven by the second driving part to approach the second connecting part 322 in the sheet metal 310. Then, the third positioning part positions the second connecting part 322, positions the second connecting part 322 in the groove 311 of the sheet metal 310, and then the first connecting part 321, the second connecting part 322 and the sheet metal 310 are welded together by the welding robot 300 to connect the connecting part and the sheet metal 310, thereby realizing automatic welding and improving efficiency.

[0033] It is understandable that, referring to Figure 1 The first positioning member includes a first connecting rod 111 and a plurality of connecting plates 211. The first connecting rod 111 is arranged along a second direction, which is located in a horizontal plane and is perpendicular to the first direction. The plurality of connecting plates 211 are spaced apart along the second direction on the first connecting rod 111, and a positioning groove 112 is formed between two adjacent connecting plates 211. The positioning groove 112 is arranged along the first direction. By placing the sheet metal part 310 into the positioning groove 112, the width of the positioning groove 112 matches the width of the sheet metal part 310, so that the sidewalls of the positioning groove 112 limit the displacement of the sheet metal part 310 along the second direction. Then, the two sets of second positioning members cooperate to clamp the sheet metal, thereby achieving the positioning of the sheet metal part 310.

[0034] For the positioning groove 112, specifically, refer to Figure 1The two ends of the connecting plate 211 are bent to form a positioning portion 212. Multiple connecting plates 211 are arranged at intervals, and two adjacent connecting plates 211 cooperate to form a positioning groove 112. By adjusting the distance between the two connecting plates 211, the width of the positioning groove 112 can be changed to adapt to sheet metal parts 310 of different widths, thereby improving the scope of use.

[0035] It is understandable that, referring to Figure 1 and Figure 2 The second positioning member includes a second connecting rod 125 and multiple groups of limiting members. The limiting members are connected to the movable end of the first driving member. The multiple groups of limiting members are all arranged on the second connecting rod 125. The first driving member drives the limiting member to move to position the first connecting member 321 on the second connecting rod 125. After welding is completed, the second connecting rod is reset to disengage the limiting member from the first connecting member 321.

[0036] Specifically, refer to Figure 2 and Figure 3 The limiting member includes a guide member 223 and a rotating plate 221. The first driving member drives the rotating plate 221 to rotate. The rotating plate 221 is hinged to the guide member 223. The rotating plate 221 cooperates with the second connecting rod 125 to position the first connecting member 321. Specifically, the rotating plate 221 includes a rotating plate 221 and a buckle 222. The rotating plate 221 is hinged to the guide member 223. The rotating plate 221 is provided with a nut 229. One end of the buckle 222 is provided with a screw 228. The screw 228 is threadedly connected to the nut 229. The other end of the buckle 222 is bent to form a buckle 226. The buckle 222 is rotated by the rotating plate 221, so that the buckle 226 rotates the end of the sheet metal part 310, so that the buckle 226 abuts against the first connecting member 321. The second connecting rod is located outside the end of the groove 311 of the sheet metal part 310 and abuts against the sheet metal part 310. The snap-fit ​​portion 226 extends into the groove 311, forming a front-to-back clamping with the second connecting rod 125, restricting the connecting member to the end of the groove 311. In addition, the second connecting rod is connected to the nut 229 via a screw 228. By rotating the screw 228, the relative position between the nut 229 and the screw 228 can be adjusted, thereby changing the distance between the snap-fit ​​portion 222 and the second connecting rod 125 and expanding the positioning range. It should be noted that the first driving member includes a motor 224 and a rotating shaft 225. The motor 224 drives the rotating shaft 225 to rotate. The multiple rotating plates 221 are all connected to the rotating shaft 225, so that the rotating shaft 225 can simultaneously drive the multiple rotating plates 221 to rotate.

[0037] It is understandable that, referring to Figure 1The first driving member includes a first cylinder 121, a first slide rail 122, and a first slider 123. The first slide rail 122 is arranged along a first direction. The first slider 123 is slidably connected to the first slide rail 122. The movable end of the first cylinder 121 is connected to the first slider 123, and the second connecting rod 125 is connected to the first slider 123. The first cylinder 121 drives the first slider 123 to slide along the first slide rail 122, so that the first connecting rod 111 can move smoothly and quickly to position the sheet metal part 310.

[0038] It is understandable that, referring to Figure 1 and Figure 2 The first slider 123 is provided with a mounting groove, which matches the end of the second connecting rod 125. The end of the second connecting rod 125 is provided with a clamping portion 227, which is clamped on the side of the mounting groove facing away from the second connecting rod 125. The first slider 123 is provided with a second cylinder 124, and the movable end of the second cylinder 124 can extend into the mounting groove and abut against the second connecting rod 125. By aligning the second connecting rod 125 with the mounting groove, the displacement of the second connecting rod 125 is now limited. The clamping portion 227 is set on the side of the mounting groove facing away from the second connecting rod 125, so that when the clamping portion 227 abuts against the end of the mounting groove, the displacement of the second connecting rod 125 is limited. Then, the telescopic rod of the second cylinder 124 is extended into the mounting groove and abuts against the second connecting rod 125, so that the second connecting rod 125 is stabilized in the groove 311, thereby improving the movement stability. At the same time, when disassembling the second connecting rod 125, the second connecting rod 125 can be removed from the mounting groove by resetting the second cylinder 124, which is convenient for disassembly.

[0039] It is understandable that, referring to Figure 1 The second driving member includes a third cylinder 131, a second slide rail 132, and a second slider 133. The second slide rail 132 is arranged along the second direction, and the second slider 133 is slidably connected to the second slide rail 132. The movable end of the third cylinder 131 is connected to the second slider 133. The third cylinder 131 drives the second slider 133 to slide on the second slide rail 132, so that the third positioning member moves up and down. At the same time, the cooperation between the second slide rail 132 and the second slider 133 makes the third positioning member move smoothly. When the third positioning member completes the positioning of the second connecting member 322, the third cylinder 131 resets, so that the third positioning member moves upward to avoid interference with the welding robot arm during welding.

[0040] It is understandable that, referring to Figure 1The third positioning member includes two fourth cylinders 231 and two clamping blocks 232. The two fourth cylinders 231 drive and cooperate to drive the two clamping blocks 232 to move toward or away from each other. The fourth cylinders 231 drive the two clamping blocks 232 to move toward each other, so that the two clamping blocks 232 clamp the second connecting member 322 and make the second connecting member 322 reach the set position, thereby realizing the positioning of the second connecting member 322. After the positioning is completed, the two fourth cylinders 231 are reset.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
