Battery case, robot

Abstract

The invention provides a battery box, a robot. A battery box, includes a first battery accommodation chamber for accommodating a first battery, a second battery accommodation chamber for accommodatingthe second battery, the first battery receiving cavity having a first positive terminal for transmitting electrical energy of the first battery, first negative terminal, The second battery accommodating cavity has a second positive terminal for transmitting electric energy of the second battery, a second negative terminal, the first positive terminal being short-circuited with the second positiveterminal, and the first negative terminal being short-circuited with the second negative terminal to ensure that the encoder is continuously powered when the first battery or the second battery is replaced. The second battery accommodating cavity includes a second positive terminal for transmitting electric energy of the second battery, a second negative terminal, the first positive terminal being short-circuited with the second positive terminal and the first negative terminal being short-circuited with the second negative terminal. According to the battery box of the invention, the robot can ensure that the encoder can still be continuously supplied with power when the battery is replaced, and effectively prevent the encoder from losing information due to power failure.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, and in particular relates to a battery box and a robot. Background technique [0002] Industrial robots are composed of three parts: main body, drive system and control system, and are widely used in assembly, handling, welding and other fields. As an important part of the drive system, the absolute encoder is installed on the servo motor to measure information such as magnetic pole position, motor rotation angle and speed. However, after the driver is powered off, the encoder needs to be powered by an external battery. The traditional method is to directly connect the external power line of the encoder to the power supply battery. However, since there is only a single battery accommodating chamber in the existing battery box, this results in the lack of necessary power supply holding parts when the battery is insufficient and needs to be replaced. As a result, when the battery is ...

Problems solved by technology

However, since there is only a single battery accommodating chamber in the existing battery box, this results in the lack of necessary power supply holding parts when the battery is insufficient and needs to be replaced. As a result, when the battery is replaced, the encoder is powered off, and the encoder will be disconnected when the battery is powered off. This phenomenon is not conducive to the control of the robot, so it is particularly important to ensure that the encoder is continuously powered on when the battery is replaced; In the case of power failure, the power of the battery cannot be detected, so that the replacement of the battery is not timely, and when the battery power is insufficient or even exhausted, the encoder will also be powered off again. Therefore, in view of the aforementioned problems, the present invention is proposed
