[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The welding process is heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction. Due to its unique advantages, it is used in the precision welding of micro and small parts.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3The button battery laser ring welding device shown includes a bracket 1, a device body 2 fixedly connected to the top of the bracket 1, a welding component 3 and a rotating wheel 4 fixedly connected to the bottom of the device body 2, the rotating wheel 4 being connected to the motor output shaft inside the device body 2, a first baffle 5 fixedly connected inside the rotating wheel 4, and multiple arc-shaped components 6 slidably connected to the outer wall of the rotating wheel 4, with a second baffle 7 fixedly connected inside the arc-shaped components 6; and a welding assembly, which assists the operator in using the laser ring welding device, and is connected to the rotating wheel 4 and the arc-shaped components 6.

[0020] like Figures 1 to 3 As shown, the welding assembly includes a first spring 8 disposed between the first baffle 5 and the second baffle 7. The first spring 8 is inserted into the inside of the rotating wheel 4 and the arc-shaped part 6. A placement part 9 is fixedly connected to the outer wall of the arc-shaped part 6. The placement part 9, together with the arc-shaped part 6, forms a horn-shaped profile. This allows the operator to insert the button battery 12 through the horn opening of the placement part 9 and move the button battery 12 to the top of the gear 10 inside the placement part 9, where it is limited. The horn-shaped profile guides and limits the button battery 12, improving the success rate and user experience of the operator installing the button battery 12. The discharge groove inside the placement part 9 allows the operator to insert an unwelded button battery 12 through the inlet of the placement part 9 and squeeze the welded button battery 12. The welded button battery 12 will then detach from the welding assembly through the discharge groove of the placement part 9, facilitating the replacement of the button battery 12 and improving the efficiency of the operator in welding the button battery 12. A gear 10 is rotatably connected inside the placement part 9, and a gear ring 11 meshes with the outer wall of the gear 10. The gear ring 11 is fixedly connected to... On the outer wall of the rotating wheel 4, a button battery 12 is provided on the top of the gear 10. The top of the gear 10 has a shallow groove that matches the contour of the button battery 12, and the groove has rounded corners. This allows the operator to easily insert the button battery 12 into the groove, where it is limited by the second spring 14 and the pressure member 13. This prevents the button battery 12 from shifting from the gear 10 without external force. The rounded corners on the shallow groove of the gear 10 also facilitate the pushing of the button battery 12 out of the groove. The top of the button battery 12 is provided with the pressure member 13, which is inserted into... Inside the placement component 9, a second spring 14 is fixedly connected between the pressure component 13 and the arc-shaped component 6. A trigger rod 15 is slidably connected to the top of the arc-shaped component 6. Inclined surfaces are provided at both ends of the trigger rod 15. A positioning slot 16 is provided at the top of the rotating wheel 4. The distance between the trigger rod 15 and the positioning slot 16 is the same as the distance that the gear 10 rotates one revolution along the outer wall of the gear ring 11. A push switch 17 and a stop block 18 are fixedly connected to the bottom of the welding component 3. The horizontal height of the welding component 3 is higher than that of the placement component 9 to prevent the placement component 9 from being blocked and jammed by the welding component 3.

[0021] Working principle: When the operator needs to use the laser ring welding device, the device is first started via the controller (not shown), which connects the welding part 3 to the power supply, causing the rotating wheel 4 to rotate. At this time, the operator can manually insert the button battery 12 through the inlet of the placement part 9. Under the guiding and limiting action of the placement part 9, the button battery 12 moves between the gear 10 and the pressure part 13. The button battery 12 pushes the pressure part 13 to slide along the inside of the placement part 9 and compresses the second spring 14 until the bottom of the button battery 12 is inserted into the shallow groove at the top of the gear 10. Then the button battery 12 is released. Then, as the rotating wheel 4 continues to rotate, the rotating wheel 4 will pass through the first baffle. 5 and the first spring 8 push the second baffle 7 and the arc-shaped part 6 to rotate, so that the arc-shaped part 6 drives the button battery 12 on the top of the gear 10 to rotate through the placement part 9. At this time, the relative position of the gear 10 and the gear ring 11 remains unchanged. When the trigger rod 15, which is slidably connected to the top of the arc-shaped part 6, touches and presses the push switch 17, the laser head at the bottom of the welding part 3 aligns with a point at the annular connection between the shell and the cap of the button battery 12. The trigger rod 15 is blocked and limited by the stop block 18. After the push switch 17 is pressed, the welding part 3 begins to work to weld the connection between the shell and the cap of the button battery 12. After the trigger rod 15 is blocked by the stop block 18, the rotating wheel 4 cannot pass through. The first baffle 5 and the first spring 8 push the second baffle 7 and the arc-shaped component 6 to rotate, causing the first spring 8 to be compressed. This causes the gear ring 11 on the rotating wheel 4 to drive the gear 10 to rotate. The rotation of the gear 10 drives the button battery 12 to rotate, allowing the laser head of the welding component 3 to perform annular welding on the annular connection between the button battery 12's casing and cap. After the button battery 12 rotates once and is welded by the laser head of the welding component 3, the positioning slot 16 on the rotating wheel 4 moves to the bottom of the trigger rod 15. Since the two ends of the trigger rod 15 are inclined surfaces, the trigger rod 15, driven by the first spring 8 through the arc-shaped component 6, is relatively compressed by the baffle 18. The trigger rod 15 descends into the positioning slot 16 and stops being blocked by the stop block 18. It then begins to move together with the rotating wheel 4. At this time, the pressing switch 17 loses the pressure of the trigger rod 15, and the welding part 3 is de-energized and stops welding. After the trigger rod 15 is driven past the stop block 18, the first spring 8 will reset and push the second stop plate 7 and the arc-shaped part 6 to reset. The arc-shaped part 6 pushes the trigger rod 15 to disengage from the positioning slot 16 through the inclined surface at the bottom and is supported by the top of the rotating wheel 4 again. This causes the gear 10 to rotate one revolution along the outer wall of the gear ring 11 to reset, so as to achieve the effect of quickly circumferential welding of the button battery 12 shell and cap connection.

[0022] Once the button battery 12 has been welded and is moving away from the welding part 3, the worker can hold the unwelded button battery 12 and insert it into the opening of the placement part 9. The welded button battery 12 is then squeezed to detach from the top of the gear 10 and the inside of the placement part 9. The unwelded button battery 12 is then pressed into the shallow groove at the top of the gear 10 by the second spring 14 through the pressure part 13, waiting to be welded again by the welding part 3. This achieves the effect of quickly replacing the button battery 12, reducing the worker's operating steps and improving the welding efficiency of the button battery 12.
