Technical Field

[0001] The utility model belongs to the field of robot charging equipment, and in particular relates to a robot contact charging device. Background Art

[0002] There are two ways to charge the rail-mounted inspection robot with its own battery: wired and wireless. Although wireless charging is contactless and can avoid sparks caused by contact, it is suitable for some specific environments in the factory, but it has high requirements for robot positioning, so it often fails to charge during on-site use. In many factory environments, more stable wired charging can be used in some scenarios with low requirements. In order not to affect the automated operation of the robot, the wired charging device should be part of the robot structure, and its charging should not be manually intervened. However, in some working conditions where contact charging can be used, wireless charging cannot be charged or the charging power is low due to the positioning accuracy not meeting the requirements.
