Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a gripper 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 before formation and capacity 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 in line with production efficiency.

[0015] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0016] Example

[0017] Please see Figure 1This embodiment provides a gripper mechanism for a chemical composition and capacity forming crane, including a fixed frame 1, a linear guide rail 2, a power unit 3, a movable connecting plate 4, several fixed clamping blocks 5, and several movable clamping blocks 6. The linear guide rail 2 and the power unit 3 are mounted on the fixed frame 1. The several fixed clamping blocks 5 are equidistantly fixed on the linear guide rail 2. The movable connecting plate 4 is movably mounted on the linear guide rail 2. The several movable clamping blocks 6 are equidistantly fixed on the movable connecting plate 4, corresponding to the several fixed clamping blocks 5 one-to-one. Each movable clamping block 6 and its corresponding fixed clamping block 5 form a vertical clamping station for the battery cell. A second spring 7 is provided between each movable clamping block 6 and its corresponding fixed clamping block 5. The output end of the power unit 3 is connected to the movable connecting plate 4. When gripping a battery cell, the power unit 3 drives the movable connecting plate 4 to move along the linear guide rail 2, thereby causing several movable clamping blocks 6 to move closer to the fixed clamping block 5 to grip the battery cell. The second spring 7 provides a buffering effect. When releasing the battery cell, the power unit 3 drives several movable clamping blocks 6 away from the fixed clamping block 5, thereby releasing the battery cell. This gripper mechanism can grip a row of battery cells at once, and it uses a vertical gripping method instead of the traditional horizontal gripping method. The same space area can grip more battery cells, which helps to improve production efficiency and is suitable for mass production of lithium batteries.

[0018] The power unit 3 includes a motor base 31, a servo motor 32, a reducer 33, a coupling 34, a drive shaft 35, and a connecting block assembly 36. The servo motor 32 and the reducer 33 are mounted on the motor base 31. The drive shaft 35 is rotatably mounted on the motor base 31 and is connected to the movable connecting plate 4 via the connecting block assembly 36. The output shaft of the servo motor 32 is connected to the reducer 33 and is connected to the drive shaft 35 via the coupling 34. The servo motor 32 drives the drive shaft 35 to rotate through the reducer 33, thereby driving the movable connecting plate 4 to move. A positioning sensor 37 is provided on one side of the motor base 31, and a sensing device 38 corresponding to the positioning sensor 37 is provided on the drive shaft 35. When the positioning sensor 37 senses the sensing device 38, it indicates that the movable clamping block 6 has reached its position, and the battery cell has been clamped.

[0019] A limiter 8 is installed on the fixed plate frame 1, and a limiting device 9 corresponding to the limiter 8 is installed on the movable connecting plate 4. The limiting device 9 includes a fixed base 91, a buffer guide rod 92, a buffer block 93, and a first spring 94. The fixed base 91 is installed on the fixed plate frame 1, and the buffer block 93 is movably connected to the fixed base 91 through the buffer guide rod 92 and corresponds to the limiter 8 on the left and right. The first spring 94 is sleeved on the buffer guide rod 92 and located between the fixed base 91 and the buffer block 93. When the movable connecting plate 4 moves the movable clamping block 6 into position, the limiting device 9 touches the limiter 8, and the buffer block 93 achieves buffering under the action of the first spring 94.
