Abstract: A drive structure of a desktop robotic arm is disclosed, including a base and a turntable. The base is internally provided with a turntable drive motor and a turntable drive shaft, the turntable drive motor is drive-connected to the turntable drive shaft, and the turntable drive shaft is drive-connected to the turntable. The turntable is provided with an upper arm drive motor and a forearm drive motor. The turntable drive motor, the upper arm drive motor and the forearm drive motor are all servo motors with absolute value encoders. According to the drive structure of the desktop robotic arm, by using servo motors as the drive motors for controlling the turntable, an upper arm and a forearm, for which the absolute value encoders are correspondingly configured, control accuracy and driving power can be improved. Further, the present invention also discloses a desktop robotic arm and a robot.

Abstract: The present invention relates to electrode tabs and batteries. The electrode tab includes a first metal strip and a metal connector connected to the first metal strip. A melting point of the metal connector is lower than a melting point of the first metal strip, or a solidus temperature of the metal connector is lower than a solidus temperature of the first metal strip, or a liquidus temperature of the metal connector is lower than a liquidus temperature of the first metal strip. The electrode tab has the advantages of regular shape, which are not only easy to install and assemble, saving assembly costs, but also not easy to be damaged in the process of assembly, transportation and storage. The electrode tab does not affect an overall size of the battery, is more suitable for use in scenarios such as small miniature batteries and power batteries.
