The welding gun 43 is fixedly set on the moving seat 42, and the welding gun 43 is set downwardly toward one side of the interface 61.
[0037] Reference Figure 3-Figure 7 After the steel strip roll 6 is limited by the limiting component 2, the interface 61 is closed by the closing component 3, and then the operator places the two square iron sheets 62 on the workbench 1, so that the two square iron sheets 62 are respectively located at the two ends of the interface 61, so that the square iron sheets 62 abut against the steel strip roll 6, and then the driving member 41 drives the moving seat 42 to move toward one side of the steel strip roll 6, so that the welding gun 43 welds the interface 61 and the two square iron sheets 62. During the whole process, the operator only needs to place the steel strip roll 6 and the square iron sheets 62, which reduces the learning cost and facilitates the operator's welding operation on the rim.
[0038] Reference Figure 3-Figure 7 The limiting assembly 2 includes a driving member 21, a fixed shaft 22 and two pressure rods 23. The fixed shaft 22 is fixedly arranged on the workbench 1. One end of the pressure rod 23 rotates on the fixed shaft 22 along the horizontal axis direction.

The two pressure rods 23 are both located inside the steel strip roll 6 and are respectively used to press the two ends of the steel strip roll 6. The driving member 21 is used to drive the two pressure rods 23 to rotate.
[0039] Reference Figure 3-Figure 7 The two ends of the steel strip roll 6 are pressed respectively by two pressure rods 23 to position the steel strip roll 6. After the two pressure rods 23 move the steel strip roll 6 away, the operator can take out the steel strip roll 6.

The first cylinder 33 is located on the side of the movable rod 231 away from the spring 32. The piston rod of the first cylinder 33 extends toward the side of the movable rod 231 and abuts on the movable rod 231. The spring 32 drives the movable rod 231 to always move toward the side of the first cylinder 33.
[0042] Reference Figure 3-Figure 7 After the two pressure rods 23 press the two ends of the steel strip coil 6, the interface 61 of the steel strip coil 6 may not be closed at this time, and then the piston rod of the first cylinder 33 is driven to extend, and one end of the steel strip coil 6 pressed by the movable rod 231 can move toward the other end, thereby closing the interface 61. After the welding of the steel strip coil 6 is completed, the two pressure rods 23 rotate upward to remove the steel strip coil 6, and then the piston rod of the first cylinder 33 contracts, and the spring 32 drives the piston rod to reset.

Two limit blocks 13 are fixed on the workbench 1, and the two limit blocks 13 are respectively located on both sides of the baffle 5. When the baffle 5 rotates toward the side of the steel strip coil 6 to abut against the limit blocks 13, the baffle 5 is in an inclined state, and the baffle 5 faces and blocks the welding gun 43; when the baffle 5 rotates toward the side away from the steel strip coil 6 to abut against the limit blocks 13, the baffle 5 is located below the steel strip coil 6. Since the welding gun 43 will generate dazzling light when welding, the baffle 5 can protect the eyes of the operator.
[0046] Reference Figure 3-Figure 7 When the piston rod of the second cylinder 211 contracts, the pressure rod 23 acts on the baffle 5 and drives the baffle 5 to rotate toward the side away from the steel strip coil 6 until it abuts against the limit block 13.
[0047] Reference Figure 3-Figure 7 When the piston rod of the second cylinder 211 contracts, the pressure rod 23 tilts upward and moves away from the steel strip roll 6, which indicates that the welding is completed. During the tilting process of the pressure rod 23, the pressure rod 23 can abut against the baffle 5, pushing the baffle 5 to rotate toward the side away from the steel strip roll 6, so that the baffle 5 opens automatically, which can reduce the step of the operator manually opening the baffle 5, thereby improving work efficiency.
[0048] Reference Figure 3-Figure 7 In order to facilitate the operator to place the steel strip roll 6 in the correct position, so that the pressure rod 23 presses its end, and the subsequent interface 61 welding operation, a standard strip 14 is attached to the surface of the workbench 1. When placing the steel strip roll 6, the operator aligns the end of the steel strip roll 6 that is not pushed by the movable rod 231 with the standard strip 14.
