[0002] Copper foil is made of copper sheets and other metals in a certain proportion. Copper foil can be made by using copper sheets and nickel-plated sheets. When welding copper sheets and nickel-plated sheets, traditional welding jigs need to position copper sheets and nickel-plated sheets on the welding jig in sequence. However, due to the small thickness of copper sheets and nickel-plated sheets, positioning is inconvenient, thus increasing the welding preparation time and reducing the welding production efficiency.

[0003] In view of this, it is necessary to provide an automatic copper foil welding line. Summary of the Invention

[0012] A welding method for a copper foil welding line includes the following steps:

[0013] S1. The first conveyor line receives the products formed by the stamping machine tool and conveys them to the side of the receiving tooling. During the conveying process, the lateral air blowing mechanism blows the products in the first conveyor line, causing the copper sheets to abut against the baffle, and then they fall into the receiving tooling.

[0014] S2. The first receiving plate receives the copper sheets, the electric cylinder drives the first receiving plate to lift and lower, so that the first receiving plate receives 30 layers of sheet materials. The second cylinder drives the first positioning plate to move towards the side of the second side plate, causing the first positioning plate and the second side plate to respectively abut against both sides of the copper sheet, and then the second cylinder drives the first positioning plate to reset. At this time, part of the copper sheet extends out of the bottom plate.

[0015] S3. The first rotary cylinder rotates, driving the third cylinder to rotate horizontally, then the third cylinder drives the fourth cylinder to move towards the side of the receiving tooling. Finally, the first cylinder gripper grabs the part of the copper sheet that extends out of the bottom plate, and then the first rotary cylinder rotates, driving the output end of the third cylinder to correspond to the weighing tooling. Then the third cylinder drives the fourth cylinder to move above the weighing tooling, and the fourth cylinder drives the first cylinder gripper to move downwards to place several copper sheets in the weighing tooling.

[0016] S4. The linear module drives the nickel-plated sheet suction component to be located above the nickel-plated sheet feeding tooling and the copper sheet suction component to be located above the weighing tooling. Subsequently, the nickel-plated sheet suction component sucks the nickel-plated sheets, the copper sheet suction component sucks the copper sheets on the weighing tooling, and then the linear module drives the nickel-plated sheet suction component and the copper sheet suction component to place the copper sheets and nickel-plated sheets on the positioning tooling.

[0017] S5. Positioning tooling positions the copper sheet and nickel-plated sheet: The fifth cylinder drives the second positioning plate to cooperate with the second material receiving plate to position the copper sheet and nickel-plated sheet, so that the copper sheet and nickel-plated sheet completely overlap.

[0018] S6. The robotic arm transfers the copper sheet and nickel-plated sheet in the positioning tooling to the welding machine.

[0021] Advantages of the invention: It can effectively position the copper sheet and nickel-plated sheet, quickly complete the welding of the copper sheet and nickel-plated sheet, and improve production efficiency and welding accuracy. Description of the Drawings

[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings.

[0031] As Figure 1 、 Figure 2 shown, an automatic copper foil welding line provided by an embodiment of the present application includes a stamping machine 1, a first conveyor line 2 for receiving the copper sheet 001 stamped and formed by the stamping machine 1, a baffle 3 arranged on one side of the first conveyor line 2, a lateral air blowing mechanism arranged on the other side of the first conveyor line 2, a frame 4 docked with the first conveyor line 2, a material receiving tooling 5 arranged on the frame 4 for receiving the copper sheet 001 in the first conveyor line 2, a positioning tooling 6 arranged on the frame 4 for positioning the copper sheet 001 and the nickel-plated sheet 002, a weighing tooling 7 arranged on the frame 4, a first transfer mechanism 8 arranged on the frame 4 for transferring the copper sheet 001 from the material receiving tooling 5 to the weighing tooling 7, a nickel-plated sheet feeding tooling 9 arranged on the frame 4, a second transfer mechanism 10 arranged on the frame 4, a plurality of welding machines 11 arranged on one side of the frame 4, a camera 19 for detecting the front and back of the nickel-plated sheet 002, a robot arm 18 for transferring the copper sheet 001 and the nickel-plated sheet 002 from the positioning tooling 6 to the welding machines 11, a finished product conveyor line 12 arranged on one side of the plurality of welding machines 11, a third transfer mechanism 13 for transferring the finished product from the welding machines 11 to the finished product conveyor line 12, and a receiving box 14 arranged at the end of the finished product conveyor line 12.

[0032] During actual use, the first conveyor line 2 receives the products formed by the stamping machine tool 1 and conveys them towards the receiving tooling 5. During the conveying process, the lateral air-blowing mechanism blows the products on the first conveyor line 2, causing the copper sheet 001 to abut against the baffle 3 and then fall into the receiving tooling 5. Then, the first transfer mechanism 8 transfers the copper sheet 001 in the receiving tooling 5 to the weighing tooling 7. Subsequently, the weighing tooling 7 weighs the copper sheet 001. Then, the second transfer mechanism 10 transfers a copper sheet 001 on the weighing turntable to the positioning tooling 6 and transfers the nickel-plated sheet 002 on the nickel-plated sheet feeding tooling 9 onto the copper sheet 001 on the positioning tooling 6. The positioning tooling 6 positions the copper sheet 001 and the nickel-plated sheet 002. Subsequently, the robotic arm 18 transfers the copper sheet 001 and the nickel-plated sheet 002 to the welding machine 11, and the welding machine 11 welds the copper sheet 001 and the nickel-plated sheet 002. The third transfer mechanism 13 transfers the welded copper sheet 001 and nickel-plated sheet 002 to the finished product conveyor line 12 and then sends them to the receiving box 14.

[0033] In the above design, the copper sheet 001 and the nickel-plated sheet 002 can be effectively positioned, and the welding of the copper sheet 001 and the nickel-plated sheet 002 can be completed quickly, improving the production efficiency and the welding accuracy.

[0034] Specifically: As Figure 3 shown, the baffle 3 includes a first plate 31 vertically arranged on the first conveyor line 2 and a second plate 32 horizontally and fixedly arranged at the upper end of the first plate 31.

The electric cylinder 51 drives the first receiving plate 52 to move up and down, enabling the first receiving plate 52 to receive 30 layers of sheet materials. The second air cylinder 53 drives the first positioning plate 54 to move towards the second side plate 523, causing the first positioning plate 54 and the second side plate 523 to respectively abut against both sides of the copper sheet 001. Subsequently, the second air cylinder 53 drives the first positioning plate 54 to reset. At this time, the copper sheet 001 partially extends out of the bottom plate 521;

[0037] In the above design, the collection and positioning of multiple layers of copper sheets 001 can be completed at one time.

[0038] Specifically: as Figure 5 shown, the first transfer mechanism 8 includes a first rotary cylinder 81 disposed on the frame 4 with its output end facing upward, a third cylinder 82 horizontally disposed at the output end of the first rotary cylinder 81, a fourth cylinder 83 vertically disposed at the output end of the third cylinder 82, and a first cylinder gripper 84 fixedly disposed at the output end of the fourth cylinder 83.

[0039] During actual use, the first rotary cylinder 81 rotates, driving the third cylinder 82 to rotate horizontally. Then, the third cylinder 82 drives the fourth cylinder 83 to move towards the receiving tooling 5 side. Finally, the first cylinder gripper 84 grabs the part of the copper sheet 001 that extends out of the bottom plate 521. Then, the first rotary cylinder 81 rotates, driving the output end of the third cylinder 82 to correspond to the weighing tooling 7. Then, the third cylinder 82 drives the fourth cylinder 83 to move above the weighing tooling 7, and the fourth cylinder 83 drives the first cylinder gripper 84 to move downwards, placing a plurality of copper sheets 001 in the weighing tooling 7.

[0040] In the above design, the transfer of the copper sheet 001 can be completed quickly.

Subsequently, the nickel-plated sheet suction component 102 sucks the nickel-plated sheet 002, and the copper sheet suction component 103 sucks the copper sheet 001 on the weighing tooling 7. Then, the linear module 101 drives the nickel-plated sheet suction component 102 and the copper sheet suction component 103 to place the copper sheet 001 and the nickel-plated sheet 002 on the positioning tooling 6.

[0046] In the above design, the copper sheet 001 and the nickel-plated sheet 002 can be synchronously sucked, effectively improving the working efficiency.

[0047] Specifically: as Figure 1 shown, the number of the finished product conveyor lines 12 is two, and several welding machines 11 are symmetrically arranged in two columns. The robotic arm 18 is arranged between the two finished product conveyor lines 12, and the third transfer mechanism 13 and the second transfer mechanism 10 have the same structure.

[0048] During actual use, the welding machines 11 on both sides transfer the welded finished products to the adjacent finished product conveyor line 12 through the third transfer mechanism 13.

[0049] In the above design, the transfer of the welded finished products can be effectively completed.

The second air cylinder 53 drives the first positioning plate 54 to move towards the second side plate 523, so that the first positioning plate 54 and the second side plate 523 respectively abut against both sides of the copper sheet 001. Then the second air cylinder 53 drives the first positioning plate 54 to reset. At this time, a part of the copper sheet 001 extends out of the bottom plate 521.

[0053] S3. The first rotary air cylinder 81 rotates, driving the third air cylinder 82 to rotate horizontally. Then the third air cylinder 82 drives the fourth air cylinder 83 to move towards the receiving tooling 5. Finally, the first air cylinder gripper 84 clamps the part of the copper sheet 001 that extends out of the bottom plate 521. Then the first rotary air cylinder 81 rotates, driving the output end of the third air cylinder 82 to correspond to the weighing tooling 7. Then the third air cylinder 82 drives the fourth air cylinder 83 to move above the weighing tooling 7. The fourth air cylinder 83 drives the first air cylinder gripper 84 to move downwards, and places several copper sheets 001 in the weighing tooling 7.
