Automatic charging robot for new energy automobile

Abstract

The invention relates to an automatic charging robot for a new energy automobile. The automatic charging robot comprises a horizontally-arranged X-axis servo module, a Y-axis servo module arranged at the driving end of the X-axis servo module and perpendicular to the X-axis servo module, a multi-degree-of-freedom robot arm arranged at the driving end of the Y-axis servo module, and a mounting base arranged at the driving end of the multi-degree-of-freedom robot arm. An electric clamping jaw, a visual sensor, a laser displacement sensor and a cover opening and closing finger are respectively arranged on the mounting base. The robot can move to a plurality of charging piles at different positions, a charging cover can be automatically opened or closed through cover opening and closing fingers, the electric clamping jaw can clamp a charging gun to charge the automobile, and the position of the charging cover on the automobile and the position of a charging port in the charging cover can be accurately found out through the visual sensor; and the insertion depth of the charging gun can be secondarily confirmed through the laser displacement sensor, so that the charging gun is ensured to be fully contacted with the charging port.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle charging, in particular to an automatic charging robot for new energy vehicles. Background technique [0002] With the rapid development of new energy vehicles, the comprehensive construction of charging piles is urgent. Traditional new energy vehicles are generally charged manually. After the car is driven to a designated location, the personnel get off the car and manually open the charging port of the car and manually insert the charging connector, and then turn on the power. The operation is complicated, and it is easy to leave. Forgetting to unplug the charging connector and starting the car directly will cause damage to the car charging port and charging equipment, and may cause personal injury. [0003] At present, there are also new energy vehicle automatic charging devices on the market, such as an electric vehicle automatic charging system disclosed in the prior art 201510235...

AI Technical Summary

Problems solved by technology

Traditional new energy vehicles are generally charged manually. After the car is driven to a designated location, the personnel get off the car and manually open the charging port of the car and manually insert the charging connector, and then turn on the power. The operation is complicated, and it is easy to leave. If you forget to unplug the charging connector and start the car directly, it will cause damage to the car charging port and charging equipment, and it is more likely to cause personal injury

[0003] At present, there are also new energy vehicle automatic charging devices on the market, such as an electric vehicle automatic charging system disclosed in the prior art 201510235350.0, a new energy vehicle charging device disclosed in the prior art 201610124284.4, and a new energy vehicle charging device disclosed in the prior art 201820608154.2 Mobile charging pile and charging pile system, a fully automatic safe charging pile for new energy vehicles disclosed in the prior art 201922144852.9, a charging mechanical arm and an automatic intelligent charging device for electric vehicles disclosed in the prior art 202011133919.X, existing Although the technology can automatically charge a new energy vehicle, there are the following problems: 1. In the existing technology, the charging head is set on the mechanical arm, so that only one new energy vehicle can be charged at a time, and the charging efficiency is low. To charge multiple new energy vehicles at the same time, multiple mechanical arms are required, which not only greatly increases the manufacturing cost, but also increases the difficulty of control; 2. In the prior art, the charging cover needs to be manually opened or closed before or after charging , the degree of automation is low; another example is a user-side new energy vehicle energy storage charging station disclosed in the prior art 202010557439. : 1. When the robot arm clamps the charging head through the clamp for automatic plugging and unplugging, because the charging port positions of different models of new energy vehicles are different, some are on the head, and some are on both sides, the robot arm is easy to be entangled with the power cord; 2. When the collaborative automatic car and the multi-degree-of-freedom robotic arm are coordinated with the hierarchical motion control and collaborative operation, the control difficulty of the collaborative automatic car is greatly increased due to the different sizes of different types of new energy vehicles and the different parking positions of each person; 3. The existing technology still needs to manually open or close the charging cover before or after charging, and the degree of automation is low.
