Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5The utility model provides an embodiment of a lithium battery spot welding processing equipment, comprising a base 1, a bracket 2 is fixedly installed on the left side of the base 1, an electric telescopic rod 3 is fixedly installed on the upper end of the bracket 2, and a spot welding assembly 4 is fixedly installed on the lower telescopic end of the electric telescopic rod 3, a limited frame 8 is fixedly installed on the left end of the base 1, a second motor 9 is fixedly installed on the left end of the base 1, a turntable 10 is rotatably installed on the left end of the base 1, and the turntable 10 is connected to the output shaft of the second motor 9. The outer wall of the turntable 10 is provided with multiple groups of grooves 11, and the right end of the limit frame 8 is provided with two groups of material ports 22. A loading and unloading assembly is provided on the right end of the base 1, and an adjustment assembly is provided in the turntable 10. The device is further provided with a loading and unloading assembly through the right end part of the base 1. The loading and unloading assembly can facilitate the loading and unloading operations of the lithium battery. Finally, an adjustment assembly is provided inside the turntable 10, and the size of the inner wall of the action groove 11 on the component turntable 10 can be finely adjusted by the adjustment assembly to meet the use requirements of lithium batteries of different specifications.

[0023] Furthermore, the loading and unloading components include four groups of rotating shafts 5, which are rotatably installed in the right end of the base 1, and two groups of conveyor belts 6 are sleeved on the four groups of rotating shafts 5. Two groups of first motors 7 are fixedly installed in the right end of the base 1, and the two groups of first motors 7 are connected to the two groups of rotating shafts 5 in the right end of the base 1. The left ends of the two groups of conveyor belts 6 are aligned with the two groups of material openings 22 on the right side of the limit frame 8, and a scraper 23 is fixedly installed on the upper side of the right end of the limit frame 8. This structure drives the four groups of rotating shafts 5 and the two groups of conveyor belts 6 to rotate through the two groups of first motors 7, thereby sending the lithium batteries into the limit frame 8 or transporting the lithium batteries from the limit frame 8 for processing, which facilitates the automatic loading and unloading of lithium batteries and reduces the labor intensity of manual labor.

[0024] Furthermore, the two groups of conveyor belts 6 are V-shaped, and the left ends of the two groups of conveyor belts 6 are close to each other. This structure sets the angles of the two groups of conveyor belts 6 and separates the upper and lower materials of the lithium batteries through the two groups of conveyor belts 6 to avoid mixing of the lithium batteries.

[0025] Furthermore, the right end of the scraper 23 is tilted forward, and the right end of the scraper 23 is located between the two groups of material openings 22 at the right end of the limit frame 8. This structure enables the turntable 10 to drive multiple groups of grooves 11 to rotate according to the setting angle of the scraper 23, and the lithium batteries in the multiple groups of grooves 11 are scraped off by the scraper 23.

[0026] Furthermore, the adjusting assembly includes a first screw 12, which is rotatably mounted in the turntable 10, and a movable groove 13 is opened in the turntable 10, and a sliding sleeve 14 is slidably mounted in the movable groove 13, and the sliding sleeve 14 is connected to the lower end of the first screw 12 by a thread. The outer wall of the sliding sleeve 14 is rotatably mounted with multiple groups of connecting rods 15, and the multiple groups of grooves 11 are movably mounted with limit plates 16, and the multiple groups of connecting rods 15 are rotatably connected with the multiple groups of limit plates 16. Two groups of guide rods 17 are fixedly mounted on one side of the multiple groups of limit plates 16 that are in contact with the inner walls of the multiple groups of grooves 11, and the multiple groups of guide rods 17 are movably inserted in the turntable 10. This structure drives the sliding sleeve 14 and the multiple groups of connecting rods 15 to slide and rotate by rotating the first screw 12, and the multiple groups of connecting rods 15 drive the multiple groups of limit plates 16 to slide in the multiple groups of grooves 11, so that the multiple groups of limit plates 16 can adjust the multiple groups of grooves 11, so that lithium batteries of different specifications can be limited in the multiple groups of grooves 11.

[0027] Furthermore, the sliding sleeve 14 and the multiple groups of connecting rods 15 are connected to form a pattern and the inner wall of the movable groove 13 is umbrella-shaped. According to the shape of the inner wall of the movable groove 13, the sliding sleeve 14 drives the higher end of the multiple groups of connecting rods 15 to descend when the sliding sleeve 14 slides downward, causing the lower end of the multiple groups of connecting rods 15 to slide, and the multiple groups of limit plates 16 can be slid open.

[0028] Furthermore, a guide frame 18 is fixedly installed at the opening of the material port 22 on the rear right side of the limit frame 8, and a guide plate 19 is symmetrically installed on the front and back right sides of the guide frame 18. A bidirectional screw 20 is rotatably installed in the guide frame 18, and two groups of splints 21 are provided in the guide frame 18. The two groups of splints 21 are connected to the bidirectional screw 20 through threads. The guide frame 18 and two groups of guide plates 19 arranged in this structure adjust the limit of the conveyor belt 6 on the rear right side of the base 1 when conveying lithium batteries, so that the lithium batteries can be accurately delivered to the limit frame 8.

[0029] Furthermore, the two groups of guide plates 19 on the right side of the guide frame 18 are both arranged in an inclined shape, and the two groups of guide plates 19 are symmetrically arranged in a flared shape front and back. This structure adjusts the lithium batteries on the conveyor belt 6 according to the installation angle of the two groups of guide plates 19 on the right side of the guide frame 18, so that the lithium batteries enter the limit frame 8 from the material port 22 and maintain the middle position.

[0030] Working principle: When loading and unloading lithium batteries, Figure 2 、 Figure 3 and Figure 5As shown, the bidirectional screw 20 is rotated to drive the two groups of splints 21 to slide in the guide frame 18. The two groups of splints 21 slide close to the inner wall of the guide frame 18 to adjust the limit. Then the two groups of first motors 7 drive the four groups of rotating shafts 5 and the two groups of conveyor belts 6 to rotate. The conveyor belt 6 on the right rear side of the base 1 rotates to drive the lithium battery to be transported into the limit frame 8. The lithium battery passes through the limit adjustment between the guide frame 18 and the two groups of splints 21. The lithium battery enters from the material port 22 on the right rear side of the limit frame 8. When the lithium battery enters the limit frame 8, as shown Figure 4 As shown, the first screw 12 is rotated, and the rotation of the first screw 12 drives the sliding sleeve 14 to slide downward in the movable groove 13. The sliding sleeve 14 drives the multiple sets of connecting rods 15 to open, and the multiple sets of connecting rods 15 slide the multiple sets of limiting plates 16 in the multiple sets of grooves 11, so that the multiple sets of limiting plates 16 adjust the size of the inner walls of the multiple sets of grooves 11. The lithium battery entering the limiting frame 8 is stuck in the multiple sets of grooves 11 on the outer wall of the turntable 10. The output shaft of the second motor 9 drives the turntable 10 and the multiple sets of grooves 11 to rotate. The turntable 10 and the multiple sets of grooves 11 rotate. The lithium battery moves in a circular motion within the limit frame 8. When the lithium battery moves to the lower side of the spot welding assembly 4, the electric telescopic rod 3 drives the spot welding assembly 4 to descend, and the spot welding assembly 4 spot welds the lithium battery. As the turntable 10 and the multiple groups of grooves 11 rotate and pass through the material port 22 on the right front side of the limit frame 8, the scraper 23 scrapes the lithium batteries in the multiple groups of grooves 11 on the outer wall of the turntable 10. The two groups of rotating shafts 5 and the conveyor belt 6 on the right front side of the base 1 rotate to transport the spot-welded lithium batteries out. The above is the entire working principle of the utility model.
