Description

Technical Field

[0001] This utility model relates to the field of battery electrode rolling and feeding technology, specifically an automatic feeding device for battery electrode rolling. Background Technology

[0002] In the battery manufacturing industry, battery electrode rolling is a crucial production step. Battery electrodes are typically stored in rolls, commonly referred to as battery electrode rolls. During rolling, these rolls need to be placed on an unwinding device. Currently, placing the electrode rolls onto the unwinding device mostly involves manual operation using trolleys. However, when transporting larger electrode rolls using manually operated trolleys, instability can lead to bumps and knocks. Damage to the battery electrode rolls can cause localized peeling of the active material coating (especially in the edge areas), resulting in a reduction in the effective electrode area, decreased battery capacity, and consequently, reduced battery performance and safety. To address this, we propose an automatic feeding device for battery electrode rolling. Utility Model Content

[0003] The purpose of this invention is to provide an automatic feeding device for rolling battery electrode sheets, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for rolling battery electrode sheets, comprising an electric railcar, a guide rail, and an electrode roll support, wherein the electric railcar slides laterally within the guide rail, characterized in that: a lifting device is fixedly connected above the electric railcar, a lifting arm is provided on one side of the lifting device, the lifting arm moves vertically up and down along the lifting device, a motor is provided inside the lifting arm, the motor is rotatably connected to a lead screw, and two gripping parts are threaded to both ends of the lead screw.

[0005] The gripper includes a sliding seat with a threaded hole in the middle, which engages with the thread on the surface of the lead screw, and a lifting ring at the bottom of the sliding seat.

[0006] The lifting arm is provided with guide rods on both sides of the lead screw, and guide holes are provided on both sides of the threaded hole of the sliding seat. The guide holes are slidably connected to the guide rods.

[0007] The inner side of the lifting ring is equipped with a guide slope.

[0008] The threads on both sides of the lead screw have opposite directions, with one side being clockwise and the other being counterclockwise.

[0009] The lifting device has a control panel on one side, which controls the electric railcar, the lifting device, and the motor.

[0010] Several placement slots are provided above the electrode roll support.

[0011] This utility model has at least the following beneficial effects:

[0012] In use, this invention employs an electric railcar, a lifting device, and a gripper for feeding, avoiding potential errors and instabilities that can occur when manually handling large battery electrode rolls. The electric railcar moves along the guide rail to the battery electrode roll position, and the lifting device controls the height. The gripper completes the gripping operation through the opening and closing of a motor, accurately gripping and placing the battery electrode roll. This effectively prevents the electrode roll from colliding with other objects during transportation, thus ensuring the integrity and quality of the electrode roll and improving battery performance and safety.

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] Example 1

[0020] Please see Figures 1 to 4This utility model provides a technical solution: an automatic feeding device for rolling battery electrode sheets, including an electric railcar 1, a guide rail 2 and an electrode roll support 3. The electric railcar 1 slides horizontally within the guide rail 2. The feature is that a lifting device 4 is fixedly connected above the electric railcar 1. A lifting arm 5 is provided on one side of the lifting device 4. The lifting arm 5 lifts and lowers vertically along the lifting device 4. A motor 6 is provided inside the lifting arm 5. The motor 6 is rotatably connected to a lead screw 7. Two gripping parts 8 are threaded to both ends of the lead screw 7.

[0021] When feeding is required, the operator issues a command via control panel 41 to control the electric railcar 1 to slide laterally within guide rail 2. The electric railcar 1 moves along guide rail 2 to the unwinding device 9. After the electric railcar 1 reaches the unwinding device 9, the operator again controls the lifting device 4 via control panel 41 to start, causing the lifting arm 5 to descend vertically along the lifting device 4. At the same time, the motor 6 is started. Because the threads on both sides of the lead screw 7 are in opposite directions, when the motor 6 rotates, the lead screw 7 drives the gripping parts 8 at both ends to move synchronously towards the center through guide holes 51 and guide rods 84. The sliding seats 81 of the gripping parts 8 pass through... The threaded hole 82 moves on the lead screw 7, and the lifting ring 83 approaches the two ends of the pole roll 33 of the unwound battery pole roll 32. When the two ends of the pole roll 33 enter the lifting ring 83, the motor 6 stops rotating, the lifting device 4 is started, and the lifting arm 5, carrying the gripper 8 and the unwound battery pole roll 32, rises vertically. Then, the electric railcar 1 is controlled to slide on the guide rail 2 and move to the top of the pole roll bracket 3. The lifting device 4 is started again, and the lifting arm 5 is lowered to place the unwound battery pole roll 32 into the empty placement slot 31 of the pole roll bracket 3, thereby removing the used battery pole roll 32.

[0022] Starting motor 6 causes lead screw 7 to rotate in the opposite direction, and gripper 8 moves to both sides, releasing the unwound battery electrode roll 32's electrode shaft 33. After releasing the unwound electrode roll, electric railcar 1 moves on guide rail 2 above the unused battery electrode roll 32, allowing gripper 8 to grasp the unused battery electrode roll 32's electrode shaft 33. Then, electric railcar 1 moves above unwinding device 9, and lifting arm 5 is lowered via lifting device 4 to place the unused battery electrode roll 32 onto unwinding device 9. Motor 6... Rotation causes the gripper 8 to move to both sides, releasing the unused battery coil 32 and completing the feeding operation. This avoids shaking during manual handling. The lifting arm 5 controls the gripper 8 via the motor 6. The inner side of the lifting ring 83 on the gripper 8 is equipped with a guide slope 831. When gripping the coil 33, the guide slope 831 can guide the coil 33 smoothly into the lifting ring 83. The whole process is stable and precise, reducing the possibility of the coil colliding with other objects and effectively avoiding damage to the coil during the feeding process.

[0023] Example 2

[0024] Please see Figure 4In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the inner side of the lifting ring 83 is provided with a guide slope 831. The guide slope 831 on the inner side of the lifting ring 83 plays a guiding role, which makes it easier for both ends of the pole roll 33 to smoothly enter the lifting ring 83 and reduces collisions.
