[0034] By fixing the circuit board on the placement plate 200 with the fixing member 500, the circuit board can be prevented from shifting; then, by moving the welding member 110 downward, the circuit board can be welded. After welding is completed, by rotating the placement plate 200, the placement plate 200 can be inclined, and the welding slag on the placement plate 200 will slide to the lower end of the placement plate 200.

[0045] It can be understood that the specific setting position and specific connection method of the electric telescopic rod 400 can be set according to actual needs, and no specific limitation is made here, as long as it can drive the rotating plate 300 to rotate. Exemplarily, the electric telescopic rod 400 can be arranged perpendicular to the rotating plate 300, and the electric telescopic rod 400 can be arranged near the left end of the rotating plate 300. The fixed end 410 of the electric telescopic rod 400 can be fixedly connected to the inner bottom wall of the fixed box, and the telescopic end of the electric telescopic rod 400 is hinged to the bottom of the rotating plate 300 through a third pin shaft.

By driving the driving motor, the rotating shaft can be driven to rotate, thereby driving the rotating plate 300 to rotate. Of course, the rotating shaft can also be directly fixedly connected to the placing plate 200, and no more details will be elaborated here.

[0047] Optionally, in some embodiments, refer to Figure 2 , a first sliding groove 310 is formed on the rotating plate 300, a sliding block 210 is arranged on the placing plate 200, at least part of the sliding block 210 extends into the first sliding groove 310, and the sliding block 210 is movable along the length direction of the first sliding groove 310.

The plurality of retaining grooves 311 are arranged at intervals along the length direction of the first sliding groove 310. By pulling and rotating the first pull rod 220, the retaining piece 221 can be embedded into different retaining grooves 311, so as to limit the sliding of the sliding block 210 and fix the placing plate 200 on the rotating plate 300.

[0048] It can be understood that by reversely rotating the first pull rod 220, the blocking piece 221 can be rotated out of the blocking groove 311, so that the slider 210 can continue to slide in the first sliding groove 310. Of course, other limiting members can also be provided in the first sliding groove 310 to limit the sliding of the slider 210, and no specific limitations are made here.

[0049] Exemplarily, referring to Figure 2 , the placement plate 200 is disposed close to the rotating plate 300. The bottom of the placement plate 200 is fixedly connected with a slider 210.

That is to say, the front end of the first sliding groove 310 does not extend beyond the rotating plate 300. This structural setting can play a role in limiting the slider 210 and prevent the slider 210 from disengaging from the first sliding groove 310. The end of the first pull rod 220 far from the slider 210 passes through the rotating plate 300 and extends out. Optionally, a first through hole communicating with the first sliding groove 310 is formed in the rotating plate 300 for the first pull rod 220 to pass through. The inner diameter of the first through hole can be slightly larger than the diameter of the first pull rod 220 to facilitate pulling and rotating the first pull rod 220; the inner diameter of the first through hole can be smaller than the diameter of the hand wheel 222 to prevent the hand wheel 222 from entering the first through hole or the first sliding groove 310, resulting in inconvenient operation.
