[0036] Furthermore, a transmission roller 20 is rotatably sleeved on one end of the transmission rod 17 , and the transmission roller 20 is rollingly inserted inside the transmission slide rail 19 .

[0037] When in use, first start the conveyor belt 3 and the laser aligner 15, so that the conveyor belt 3 moves the battery pack to be welded to one side of the loading rack 2, and cooperates with the laser aligner 15 for calibration and alignment, and then the controller 16 controls the start of the second electric push rod 14, and the second electric push rod 14 pushes the ejection slide 11 to drive the transmission plate 18 to move along the length direction of the welding slide rail 10, and at the same time, the transmission plate 18 cooperates with the transmission slide rail 19 to pull the transmission roller 20 to drive the separation plate 9 to move downward along the length direction of the transmission slide rail 19, so that the bottom of the separation plate 9 is inserted between a connecting piece 5 near one end of the discharge port 7 and another adjacent connecting piece 5, and squeezes a connecting piece 5 to move above the discharge port 7, and then under the action of gravity, a connecting piece 5 moved above the discharge port 7 slides to the top of the ejection slide 11 and fits with one side of the push plate 13;

[0038] Then, the second electric push rod 14 is started to drive the ejection slide plate 11 to drive the push plate 13 to push the connecting sheet 5 to move in the direction of the conveyor belt 3, so that the connecting sheet 5 is attached to the electrode sheet of the battery pack, and then the laser welder 12 is started by the control controller 16 to complete the welding of the connecting sheet 5 and the electrode sheet;

[0040] Reference Figure 3 and Figure 4 A T-shaped pressing plate 21 is slidably inserted on the top of the separation plate 9, and an adaptive component is installed at one end of the T-shaped pressing plate 21;

[0042] When in use, when the second electric push rod 14 is started to cooperate with the transmission assembly to push a connecting piece 5 through the material discharge port 7, the separation plate 9 drives one end of the T-shaped pressure plate 21 to push the connecting piece 5 through the material discharge port 7 and form a conflict with the top of the ejection slide plate 11, so as to facilitate the pushing of the connecting piece 5 and reduce the jamming of the connecting piece 5 inside the material discharge port 7;

[0043] Then, when the bottom of the connecting piece 5 is not aligned with the discharge port 7, causing the connecting piece 5 to be stuck inside the material rail 4, the separation plate 9 drives the T-shaped pressure plate 21 to form a conflict with the top of the connecting piece 5, and then the T-shaped pressure plate 21 pushes out the spring 23 along the length direction of the T-shaped guide rod 22, and the spring 23 is forced to shrink and deform, and at the same time, the T-shaped pressure plate 21 passes through the separation plate 9 along the length direction of the T-shaped guide rod 22 and moves upward. In this way, when the connecting piece 5 cannot be pushed, the T-shaped pressure plate 21 is driven to move upward along the length direction of the T-shaped guide rod 22, thereby effectively reducing the wear between the T-shaped pressure plate 21 and the connecting piece 5.

[0044] Reference Figure 2 and Figure 3 The inner side of the material rail 4 is symmetrically fixedly connected with an elastic rubber strip 24 , which is installed above the material discharge port 7 , and the elastic rubber strip 24 forms an elastic resistance with one end of the connecting piece 5 .

[0045] During use, when the first electric push rod 6 is started to push the multiple connecting pieces 5 to move in the direction of the lower material port 7, a connecting piece 5 close to the side of the lower material port 7 comes into contact with the elastic rubber strip 24 and squeezes the elastic rubber strip 24 to deform. At the same time, the rebound characteristics of the elastic rubber strip 24 are utilized to clamp and fix the connecting piece 5, thereby effectively improving the installation stability of the connecting piece 5.

[0046] Reference Figure 1 and Figure 2 A resisting plate 25 is fixedly connected to the top of the base 1 , and the resisting plate 25 is installed above the conveyor belt 3 .

[0047] During use, when the second electric push rod 14 is started to push the ejection slide 11 to drive the connecting piece 5 to fit the battery pack electrode sheet at the top of the conveyor belt 3, the second electric push rod 14 pushes the connecting piece 5 to cooperate with the contact plate 25 to clamp the battery pack, thereby improving the stability of the connecting piece 5 and the electrode sheet during welding.

[0048] Reference Figure 1 and Figure 2 One end of the base 1 is fixedly connected to a support plate 26 , and the support plate 26 is inserted into the inner top of the conveyor belt 3 .

[0049] During use, when the driving conveyor belt 3 is used to transport the battery pack to be welded, the battery pack squeezes the top of the conveyor belt 3 and fits against the support plate 26, thereby utilizing the support plate 26 to improve the support stability of the conveyor belt 3 on the battery pack, further improving the stability of the battery pack welding.

[0050] The implementation principle of a lithium battery laser welding feeding device in this embodiment is as follows: first, the battery pack to be welded is moved to one side of the feeding rack 2 by starting the conveyor belt 3, and the laser calibrator 15 is used for calibration and alignment, and then the ejection slide plate 11 is pushed by starting the second electric push rod 14 to drive the transmission plate 18 to move along the length direction of the welding slide rail 10, and at the same time, the transmission plate 18 cooperates with the transmission slide rail 19 to pull the transmission roller 20 to drive the separation plate 9 to move downward along the length direction of the transmission slide rail 19, so that the bottom of the separation plate 9 is inserted between a connecting piece 5 near one end of the discharge port 7 and another adjacent connecting piece 5, and squeezes a connecting piece 5 to move above the discharge port 7, and then, under the action of gravity, a connecting piece 5 moved above the discharge port 7 slides to the top of the ejection slide plate 11 and fits with one side of the push plate 13;

[0051] At the same time, the separation plate 9 drives one end of the T-shaped pressing plate 21 to push the connecting piece 5 through the discharge port 7 and form a conflict with the top of the ejection slide plate 11, so as to facilitate the pushing of the connecting piece 5 and reduce the jamming of the connecting piece 5 inside the discharge port 7;

[0052] Then, the second electric push rod 14 is started to drive the ejection slide 11 to drive the push plate 13 to push the connecting piece 5 to move in the direction of the conveyor belt 3, so that the connecting piece 5 is fitted with the electrode sheet of the battery pack, and then the laser welder 12 is started by controlling the controller 16 to complete the welding of the connecting piece 5 and the electrode sheet. After one welding is completed, the first electric push rod 6 is started by controlling the controller 16 to push the multiple connecting pieces 5 to move closer to the lower material port 7 along the length direction of the material rail 4;

[0053] Then, when the bottom of the connecting piece 5 is not aligned with the discharge port 7, causing the connecting piece 5 to be stuck inside the material rail 4, the separation plate 9 drives the T-shaped pressure plate 21 to form a conflict with the top of the connecting piece 5, and then the T-shaped pressure plate 21 pushes out the spring 23 along the length direction of the T-shaped guide rod 22, and the spring 23 is forced to shrink and deform, and at the same time, the T-shaped pressure plate 21 passes through the separation plate 9 along the length direction of the T-shaped guide rod 22 and moves upward. In this way, when the connecting piece 5 cannot be pushed, the T-shaped pressure plate 21 is driven to move upward along the length direction of the T-shaped guide rod 22, thereby effectively reducing the wear between the T-shaped pressure plate 21 and the connecting piece 5.
