[0022] Reference Figures 1-3A battery cap welding machine with alignment effect includes a base plate 5 and a welding gun 2. The top of the base plate 5 is equipped with a moving assembly that drives the battery to rotate. The moving assembly includes a self-locking motor fixed to the bottom of the base plate 5 by bolts. The output shaft of the self-locking motor passes through the base plate 5 and is fixed to a turntable 11 by bolts. The top of the turntable 11 has multiple evenly spaced second through holes 12 for inserting batteries. By placing a battery with a cap on top into one of the second through holes 12, and then activating the self-locking motor, the output shaft of the self-locking motor drives the turntable 11 to rotate. The turntable 11 rotates the battery with the cap placed in the second through hole 12 to the bottom of the welding gun 2, where the welding gun 2 welds the battery cap. Simultaneously, another battery with a cap is placed into another second through hole 12, thus realizing the operation process of welding and placing batteries at the same time, which greatly saves processing time and improves work efficiency. A fixing frame 4 is fixed to one side of the base plate 5 by bolts. A cylinder 1 is fixed to the top of the fixing frame 4 by bolts. The output shaft of the cylinder 1 passes through the fixing frame 4 and is fixed to the carrier plate 3 by bolts. The welding gun 2 is fixed to the bottom center position of the carrier plate 3. Two symmetrically arranged connecting plates 14 are fixed to the bottom of the carrier plate 3 by bolts. A wedge block 13 is fixed to one side of each of the two connecting plates 14 by bolts. Two symmetrically arranged fixing plates 17 are fixed to the bottom of the fixing frame 4 by bolts. Two guide rods 16 are slidably connected through the fixed plate 17. A support frame 19 is welded to one end of each guide rod 16. Two symmetrically arranged pressure rollers 20 are rotatably connected between the inner walls of the support frame 19. A fixed rod 15 is welded to the other end of each guide rod 16, contacting the inclined surface of the wedge block 13. Elastic components are provided between the two support frames 19 and the two fixed plates 17. Each elastic component includes a damping spring 18 located between the support frame 19 and the fixed plate 17. One end of the damping spring 18 is fixed to the support frame 19, and the other end is fixed to the fixed plate 17. The spring force of the damping spring 18 drives the support frame 19 to move inward, activating cylinder 1. Cylinder 1 drives the carrier plate 3 to move downward. The plate 3 drives the two wedge blocks 13 downward through the two connecting plates 14, so that the inclined surface of the wedge block 13 is disengaged from the fixed rod 15. At the same time, the elastic force of the two elastic components drives the two support frames 19 to move inward. The two support frames 19 simultaneously drive the two pressure rollers 20 to move inward. The multiple pressure rollers 20 simultaneously push the battery cap to the middle position. The carrier plate 3 continues to move downward, and the carrier plate 3 drives the welding gun 2 to contact the battery cap and weld the battery cap. This achieves the alignment of the battery cap, making the battery cap accurately aligned with the battery, avoiding the phenomenon of positional displacement of the battery cap during welding, greatly improving the welding quality of the battery cap, and making the welded battery cap more solid.

[0023] In this invention, a first through hole 10 is provided on the top of the base plate 5, and the first through hole 10 can coincide with the second through hole 12. A guide frame 9 is fixed to the bottom of the base plate 5 at the position of the first through hole 10 by bolts, and the guide frame 9 is connected to the first through hole 10. The battery in the first through hole 10 is smoothly guided out through the guide frame 9, ensuring that the battery can be accurately guided to the predetermined position, thus improving the efficiency of the production process. When the second through hole 12 coincides with the first through hole 10, the battery with the cap welded in the second through hole 12 will fall back down through the first through hole 10, thereby realizing the rapid recycling of the battery. It is not necessary to manually remove the battery with the cap welded from the welding machine, which greatly improves the efficiency of battery capping.

[0024] In particular, multiple support columns 6 are evenly fixed to the bottom of the base plate 5 by bolts. A collection box 8 is provided on one side of two of the support columns 6, and the collection box 8 is located at the bottom of the guide frame 9. A lead screw 7 is rotatably connected to one side of each of the two support columns 6. Two threaded holes are symmetrically opened on one side of the collection box 8, and the lead screw 7 is threadedly connected to the threaded holes. By rotating the lead screw 7, the lead screw 7 is threadedly connected to the collection box 8, thereby realizing the function of fixing the collection box 8. When the welded battery passes through the guide frame 9, it will fall into the collection box 8 below under the action of gravity, thus avoiding the welded battery from scattering on the ground or other unwanted places, and improving the efficiency of collecting the welded battery.

[0025] Working principle: When needed, first place the battery with the cap on top into one of the second through holes 12. Then, start the self-locking motor. The output shaft of the self-locking motor drives the turntable 11 to rotate. The turntable 11 rotates the battery with the cap placed in the second through hole 12 to the bottom of the welding gun 2. Then, turn off the self-locking motor. Then, start the cylinder 1. The cylinder 1 drives the carrier plate 3 to move downward. The carrier plate 3 drives the two wedge blocks 13 downward through the two connecting plates 14, so that the inclined surface of the wedge blocks 13 disengages from the fixed rod 15. At the same time, the elastic force of the two damping springs 18 drives the two support frames 19 to move inward. The two support frames 19 simultaneously drive the two pressure rollers 20 to move inward. Through the multiple pressure rollers 20, the battery cap is pushed to the middle position. The carrier plate 3 continues to move downward. The carrier plate 3 drives the welding gun 2 to contact the battery cap and weld the battery cap. While welding, another battery with a cap is placed into another second through hole 12. After welding is completed, cylinder 1 is started. Cylinder 1 drives the carrier plate 3 to move upward. The carrier plate 3 drives the welding gun 2 to move upward. At the same time, the carrier plate 3 drives the two wedge blocks 13 to move upward through the two connecting plates 14 respectively. The inclined surface of the wedge blocks 13 pushes the fixing rod 15 to move outward. The two fixing rods 15 drive the two support frames 19 to move outward through the two guide rods 16 respectively. The two support frames 19 drive the two pressure rollers 20 to move outward at the same time, so that the multiple pressure rollers 20 are disengaged from the battery. Then the self-locking motor is started. The self-locking motor drives the turntable 11. The turntable 11 drives the welded battery in the second through hole 12 to rotate. When it rotates to the position of the first through hole 10, the welded battery will fall into the collection box 8 below under the action of gravity when passing through the guide frame 9. This process is repeated.
