Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery production technology, specifically to a gripper assembly for a formation and capacity control 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. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a gripper assembly for a chemical composition and dispensing overhead crane.
[0004] The technical solution of this utility model is as follows:
[0005] A gripper assembly for a chemical composition and decomposition overhead crane includes a power unit and a gripper row, wherein the transmission end of the power unit is connected to the gripper row.
[0006] The power unit includes a motor base, a servo motor, a transmission shaft, and a connecting clamp. The servo motor is mounted on the motor base, and the transmission shaft is rotatably mounted on the motor base. The output shaft of the servo motor is connected to the transmission shaft, and the transmission shaft is connected to a jaw row via the connecting clamp.
[0007] The gripper bar has several vertical gripping stations for battery cells in the same row.
[0008] Furthermore, the mechanical gripper assembly of the chemical reaction and dissolution crane also includes a reducer and a coupling. The output shaft of the servo motor is connected to the reducer and is connected to the transmission shaft through the coupling.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0014] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0015] Example
[0016] Please see Figure 1 This embodiment provides a gripper assembly for a formation and capacity testing crane robotic arm, including a power unit 1 and a gripper row 2. The transmission end of the power unit 1 is connected to the gripper row 2. The gripper row 2 has several vertical gripping stations for battery cells in the same row, which can grip a row of battery cells at one time. 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.
[0017] The power unit 1 includes a motor base 11, a servo motor 12, a reducer 13, a coupling 14, a drive shaft 15, and a connecting clamp 16. The servo motor 12 and the reducer 13 are mounted on the motor base 11. The drive shaft 15 is rotatably mounted on the motor base 11. The output shaft of the servo motor 12 is connected to the reducer 13 and is connected to the drive shaft 15 via the coupling 14. The drive shaft 15 is connected to the gripper row 2 via the connecting clamp 16. The servo motor 12 drives the drive shaft 15 to rotate via the reducer 13, thereby driving the gripper row 2 to move.
[0018] A positioning sensor 17 is provided on one side of the motor base 11, and a sensing device 18 corresponding to the positioning sensor 17 is provided on the transmission shaft 15. The movement of the gripper row 2 is limited by this structure. When the positioning sensor 17 senses the sensing device 18, the movement of the gripper row 12 stops, that is, it has moved into position. The movement stroke of the gripper row 12 can be designed according to the position of the feeding platform and the forming and dispensing fixture.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
