A positioning column 23 is arranged above the base 2. A passage 24 for the button battery to pass through is formed on the top surface of the positioning column 23. A conical groove 25 is formed on the top surface of the positioning column 23, and the conical groove 25 communicates with the passage 24. Support rods 27 are fixed at the bottom corners of the bottom surface of the positioning column 23. The support rods 27 are telescopic rods, and the bottom ends of the support rods 27 are fixed to the top surface of the base 2. A cylinder 28 is fixed to the top surface of the base 2, and the top end of the piston rod of the cylinder 28 is fixed to the bottom surface of the positioning column 23.

[0035] Refer to Figure 1 , Figure 3 and Figure 4 , A feeding bin 3 is arranged on one side of the top surface of the workbench 1. Side plates 13 are fixed to both side surfaces of the feeding bin 3, and the bottom surfaces of the side plates 13 are fixed to the top surface of the workbench 1. A through port 32 is formed on the inner bottom surface of the feeding bin 3. A stopper 26 is fixed to one end of the top surface of the positioning column 23 away from the feeding bin 3. Two mounting plates 31 arranged in parallel are fixed to the bottom surface of the feeding bin 3. A diversion groove 39 is fixed to the side surface of the two mounting plates 31 close to the positioning column 23. A rotating shaft 33 is rotatably mounted between the two mounting plates 31. Two parallel baffles 34 are sleeved and fixed on the outer peripheral surface of the rotating shaft 33. A plurality of partition plates 35 are fixed between the two baffles 34. The plurality of partition plates 35 are arranged at equal intervals along the circumferential direction of the baffle 34. A motor 36 is arranged on the side surface of one of the mounting plates 31, and the output shaft of the motor 36 is fixedly connected to one end of the rotating shaft 33.

[0036] Refer to Figure 1 , Figure 2 and Figure 3 , A controller 37 and a first sensor 38 are fixed to the top surface of the workbench 1. The first sensor 38 is located directly below the diversion groove 39. The output end of the first sensor 38 is electrically connected to the input end of the controller 37, and the output end of the controller 37 is electrically connected to the control end of the motor 36.

[0037] Start motor 12. The output shaft of motor 12 drives the turntable 11 to rotate. The turntable 11 drives the base 2 to rotate. When the base 2 drives the positioning post 23 to move, when the positioning post 23 moves to directly below the bottom end of the diversion groove, the first sensor 38 detects the base 2. The first sensor 38 transmits a signal to the controller 37. The controller 37 controls the start of motor 2 36, causing motor 2 36 to drive the baffle 34 to rotate, so that the button cells in the feeding bin 3 fall through the through port 32 between the two partitions 35. The baffle 34 continues to rotate. When the end of the partition 35 far from the central axis of the baffle 34 moves to the entrance of the diversion groove, the button cell rolls into the diversion groove 39, and then flows into the conical groove 25 along the diversion groove 39. Then the button cell passes through the channel 24 and falls into the groove 21, so that the button cell is stuck between the positioning post 23 and the base 2.

[0038] Refer to Figure 1 and Figure 5 , on the top surface of the workbench 1 on the side far from the feeding bin 3, two mutually parallel slide rails 1 4 are fixed. A slide block 1 41 is slidably arranged on the slide rail 1 4. The end face of the slide block 1 41 close to the turntable 11 is fixed with a connecting block 1 44. On the opposite sides of the two connecting blocks 1 44, air cylinders 1 42 are fixed. A welding needle 43 is fixed on the piston rod of the air cylinder 1 42. On the top surface of the workbench 1 on the side far from the feeding bin 3, two vibrating bowl feeders 5 are fixed. The output end of the vibrating bowl feeder 5 is fixed with a feeding track 51. On the top surface of the workbench 1, two mutually parallel slide rails 2 52 are fixed. The two slide rails 2 52 are located between the two slide rails 1 4. A slide block 2 53 is slidably arranged on the slide rail 2 52. The end face of the slide block 2 53 close to the turntable 11 is fixed with a motor 3 56. A connecting block 2 55 is fixed on the output shaft of the motor 3 56. On the opposite sides of the two connecting blocks 2 55 close to each other, pneumatic clamps 54 are fixed.

[0039] The vibrating bowl feeder 5 conveys the solder pads into the feeding track 51, so that the feeding track 51 conveys the solder pads. Then start the motor 3 56. The output shaft of the motor 3 56 drives the connecting block 2 55 to rotate 180 degrees. The connecting block 2 55 drives the pneumatic clamp 54 to rotate, so that the pneumatic clamp 54 clamps the solder pad conveyed out by the feeding track 51. After the pneumatic clamp 54 clamps the solder pad, start the motor 3 56 again, so that the output shaft of the motor 3 56 drives the connecting block 2 55 to rotate 180 degrees in the reverse direction. Then the slide block 2 53 moves towards the direction close to the turntable 11, so that the slide block 2 53 drives the pneumatic clamp 54 to move to below the positioning post 23, so that the pneumatic clamp 54 presses the solder pad tightly against the side of the button cell. Then the slide block 1 41 drives the connecting block 2 55 to move towards the direction close to the turntable 11, so that the connecting block 2 55 drives the air cylinder 1 42 to move. The air cylinder 1 42 drives the welding needle 43 to move to the welding position. Then start the air cylinder 1 42. The piston rod of the air cylinder 1 42 drives the welding needle 43 to move towards the direction close to the button cell, so that the welding needle 43 welds the solder pad on the button cell.

[0040] Reference Figure 1 and Figure 6 A material receiving box 6 is provided on one side of the workbench 1, and an inclined material guide plate 61 is fixed on one side of the top surface of the workbench 1. The bottom end of the material guide plate 61 is located above the material receiving box 6, and a second sensor 62 is fixed on the side of the material guide plate 61. The output end of the second sensor 62 is electrically connected to the input end of the controller 37, and the output end of the controller 37 is electrically connected to the control end of the cylinder 28.

[0041] When the button battery with the welding piece welded follows the base 2 to move to the position of the guide plate 61, the second sensor 62 detects the base 2 signal and transmits the detected signal to the controller 37. The controller 37 controls the cylinder 28 to start, so that the piston rod of the cylinder 28 pushes the positioning column 23 to move upward, so that the button battery is separated from the positioning column 23, so that the button battery after welding slides into the receiving box 6 through the guide plate 61.

[0042] The implementation principle of a spot welding device for primary lithium-manganese button batteries in an embodiment of this application is as follows: When spot welding of button batteries is required, the button batteries to be welded are placed in the loading bin 3, and then the first motor 12 is started. The output shaft of the first motor 12 drives the turntable 11 to rotate, causing the turntable 11 to drive the base 2 to rotate, and the base 2 drives the positioning post 23 to move. When the first sensor 38 detects the signal of the base 2 and transmits the signal to the controller 37, the controller 37 controls the second motor 36 to start. The output shaft of the second motor 36 drives the rotating shaft 33 to rotate, the rotating shaft 33 drives the baffle 34 to rotate, and the baffle 34 drives the partition 35 to rotate, so that the button batteries in the loading bin 3 fall between two adjacent partitions 35 through the through port 32. The partition 35 drives the button battery to move. When the partition 35 moves to the entrance of the diversion groove, the button battery rolls into the diversion groove, then rolls into the conical groove 25 along the diversion groove, and flows into the groove 21 through the channel 24, so that the button battery is located between the positioning post 23 and the base 2. The output shaft of the first motor 12 continues to drive the turntable 11 to rotate, so that the subsequent base 2 continues to move and feed. When the base 2 with the button battery moves to the front of the second slide rail 52, the second slide block 53 is moved in the direction close to the turntable 11, so that the second slide block 53 drives the pneumatic clamp 54 to move below the positioning post 23, and the pneumatic clamp 54 presses the welding sheet tightly against the side of the button battery. Then the first slide block 41 is moved in the direction close to the turntable 11, so that the first slide block 41 drives the second connecting block 55 to move in the direction close to the turntable 11, and the second connecting block 55 drives the first cylinder 42 to move. The first cylinder 42 drives the welding needle 43 to move to the welding position, and then the first cylinder 42 is started. The piston rod of the first cylinder 42 drives the welding needle 43 to move in the direction close to the button battery, so that the welding needle 43 welds the welding sheet on the button battery, enabling the button battery to be automatically loaded and welded during welding, thereby improving the spot welding efficiency of primary lithium-manganese button batteries.
