Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery production technology, specifically to a variable-pitch gripping mechanism for a formation and capacity crane robotic arm. Background Technology
[0002] After the cells that make up a lithium battery are manufactured, they need to undergo formation and capacity testing. Formation involves charging and discharging the cells to activate them, while capacity testing involves sorting them by capacity. Before formation and capacity testing, the cells need to be transferred. A transfer robot horizontally grasps the cells and places them in a formation and capacity testing fixture for positioning and testing. A maximum of four cells can be grasped at a time. If more grasping stations are added, the required area for the corresponding robot gripping mechanism and formation and capacity testing fixture will be very large, resulting in high costs and not being inefficient for production.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0020] Example
[0021] Please see Figure 1 This embodiment provides a variable-pitch gripping mechanism for a formation and capacity testing crane robotic arm, including a variable-pitch component 1, a first gripper component 2, and a second gripper component 3. The first gripper component 2 and the second gripper component 3 are movably disposed at the bottom of the variable-pitch component 1. Both the first gripper component 2 and the second gripper component 3 have several vertical gripping stations for battery cells in the same row, which can grip two rows of battery cells at once. Compared with the traditional horizontal gripping method, the vertical gripping method can grip more battery cells in the same space area, which helps to improve production efficiency and is suitable for mass production of lithium batteries. When gripping battery cells, the variable-pitch component 1 can adjust the distance between the first gripper component 2 and the second gripper component 3 to correspond to the battery cell placement station on the transfer platform, so that all battery cells can be gripped at once.
[0022] The variable pitch assembly 1 includes a first moving device 11, a second moving device 12, a third moving device 13, a fourth moving device 14, a first linear guide rail 15, and a second linear guide rail 16. The first linear guide rail 15 and the second linear guide rail 16 are arranged opposite each other from left to right. The first gripper assembly 2 and the second gripper assembly 3 are movably arranged on the first linear guide rail 15 and the second linear guide rail 16 from front to back. The top of the first gripper assembly 2 is movably connected to the first linear guide rail 15 and the second linear guide rail 16 through the first moving device 11 and the second moving device 12, respectively. Driven by the first linear guide 15 and the second linear guide 16, the gripper assembly 2 can move back and forth along the first linear guide 15 and the second linear guide 16 toward the second gripper assembly 3, thereby moving closer to or away from the second gripper assembly 3. The top of the second gripper assembly 3 is movably connected to the first linear guide 15 and the second linear guide 16 through the third moving device 13 and the fourth moving device 14, respectively. Driven by the third moving device 13 and the fourth moving device 14, the second gripper assembly 3 can move back and forth along the first linear guide 15 and the second linear guide 16 toward the first gripper assembly 2, thereby moving closer to or away from the first gripper assembly 2.
[0023] Specifically, such as Figure 2 As shown, the first gripper assembly 2 and the second gripper assembly 3 have the same structure, both including a fixed plate frame 21, a third linear guide rail 22, a power device 23, a movable connecting plate 24, several fixed clamping blocks 25 and several movable clamping blocks 26. The third linear guide rail 22 and the power device 23 are mounted on the fixed plate frame 21. Several fixed clamping blocks 21 are equidistantly fixed on the third linear guide rail 22. The movable connecting plate 24 is movably mounted on the third linear guide rail 22. Several movable clamping blocks 26 are equidistantly fixed on the movable connecting plate 24 and correspond one-to-one with several fixed clamping blocks 25. Each movable clamping block 26 and its corresponding fixed clamping block 25 form a vertical clamping station for the battery cell. A second spring 27 is provided between each movable clamping block 26 and its corresponding fixed clamping block 25. The output end of the power device 23 is connected to the movable connecting plate 24. When clamping the battery cell, the power unit 23 drives the movable connecting plate 24 to move along the third linear guide rail 22, thereby causing several movable clamping blocks 26 to move closer to the fixed clamping block 25 to clamp the battery cell. The second spring 27 provides a buffering effect. When releasing the battery cell, the power unit 23 drives several movable clamping blocks 26 away from the fixed clamping block 25, thereby releasing the battery cell.
[0024] The power unit 23 includes a motor base 231, a servo motor 232, a reducer 233, a coupling 234, a drive shaft 235, and a connecting block assembly 236. The servo motor 232 and the reducer 233 are mounted on the motor base 231. The drive shaft 235 is rotatably mounted on the motor base 231 and is connected to the movable connecting plate 24 via the connecting block assembly 236. The output shaft of the servo motor 232 is connected to the reducer 233 and is also connected to the drive shaft 235 via the coupling 234. The servo motor 232 drives the drive shaft 235 to rotate through the reducer 233, thereby moving the movable connecting plate 24. A position sensor 237 is provided on one side of the motor base 231, and a sensing device 238 corresponding to the position sensor 237 is provided on the drive shaft 235. When the position sensor 237 senses the sensing device 238, it indicates that the movable clamping block 26 has reached its position, and the battery cell has been clamped.
[0025] A limiter 28 is provided on the fixed plate frame 21, and a limiting device 29 corresponding to the limiter 28 is provided on the movable connecting plate 24. The limiting device 29 includes a fixed base 291, a buffer guide rod 292, a buffer block 293, and a first spring 294. The fixed base 291 is mounted on the fixed plate frame 21. The buffer block 293 is movably connected to the fixed base 291 through the buffer guide rod 292 and corresponds to the limiter 28 on the left and right. The first spring 294 is sleeved on the buffer guide rod 292 and located between the fixed base 291 and the buffer block 293. When the movable connecting plate 24 moves the movable clamping block 26 into position, the limiting device 29 touches the limiter 28, and the buffer block 293 achieves buffering under the action of the first spring 294.
[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
