Problems solved by technology

The charging head of the robot is a metal block type. This charging method has high requirements on the placement of the charging pile in the use environment. It needs to be on a relatively flat ground, otherwise there will be cases where the shrapnel gets stuck and does not charge after docking. Moreover, Since most robots use laser radar for alignment, their positioning accuracy is about + / -3cm. When the metal block charging head is docked with the charging shrapnel, it is necessary to add small laser, infrared and other sensors to assist alignment. During the alignment process, the robot You need to repeatedly correct your position, and the whole process takes a long time
[0005] The other is to set two charging connectors on the bottom of the robot. The two charging connectors are set along the width direction of the robot. The front of the charging pile is equipped with charging shrapnel. If the shrapnel is pressed for a long time, the life of the shrapnel will be reduced, and it may cause poor contact. In the case of no charging, the two charging connectors are set along the width direction of the robot at the same time. In order to ensure the success rate of charging and docking, there is a certain requirement for the width, which will greatly limit the width of the robot body. Take the 4-inch universal wheel as an example. The width of the robot should not be less than 190×2 (rotation diameter of universal wheel)+60 (tolerance of laser alignment)+60 (shrapnel width×2+spacing)=500mm, if the width of the robot is too large, it will affect the turning of the robot , the flexibility of obstacle avoidance

[0091] According to the fifth embodiment provided by the present invention, this embodiment is an optimized embodiment of the above-mentioned fourth embodiment, as Figure 8 As shown, after step S10, before step S20 also includes:

[0092] S15 The robot 1 locates the charging pile 2 according to the identification portion provided on the front of the charging pile 2.

[0093] Specifically, the identification part on the charging post 2 may be an unusual shape or a special shape or a two-dimensional code, a label, and the like. Since the first charging sheet 11 and the second charging sheet 12 are sequentially arranged along the length direction of the robot 1, only one charging sheet needs to be reserved in the width direction of the robot 1, and there is no need to reserve a gap between two charging sheets. Therefore, not only can the width of the robot 1 be reduced, but also a large enough fault-tolerant position can be reserved for the charging sheet. When the robot 1 use...

[0094] According to the sixth embodiment provided by the present invention, this embodiment is an optimized embodiment of the above-mentioned fourth or fifth embodiment, such as Figure 9 As shown, after step S20, before step S30 also includes:

[0095] S25 When the second charging connector 22 abuts against the first charging piece 11, trigger the second micro switch 27 on the charging pile 2 to close;

[0096] In step S30, the robot 1 continues to move toward the front of the charging pile 2, so that the second charging connector 22 leaves the first charging piece 11 and contacts the second charging piece 12 at the bottom of the robot 1, and makes the The first charging connector 21 provided on the front of the charging pile 2 also extends into the bottom of the robot 1 and abuts against the first charging piece 11, specifically including:

[0097] S31 When the second micro switch 27 is closed, the robot 1 is triggered to continue moving toward the front of the charging pil...

Abstract

The invention belongs to the technical field of a robot, and discloses a robot charging system and a method thereof. The charging system comprises a robot and a charging pile. The bottom of the robotis provided with a first charging plate and a second charging plate which are successively arranged in the length direction of the robot. The front surface of the charging pile is provided with a first charging plug and a second charging plug. The first charging plug and the second charging plug are arranged in a vertical direction. When the first charging plug extends into the bottom of the robotand abuts against the first charging plate and the second charging plug extends into the bottom of the robot and abuts against the second charging plate, the charging pile performs charging on the robot. According to the robot charging system, the first charging plate and the second charging plate are successively arranged in the length direction of the robot. Under a precondition that high charging abutting success rate between the robot and the charging pile is ensured, the transverse direction of the robot can be greatly reduced, namely the width of the robot can be greatly reduced, thereby improving flexibility of the robot in turning and obstacle dodging.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a robot charging system and method. Background technique [0002] In the field of logistics transportation, automated logistics transportation involving robots is more and more widely used, and many manual handling operations are now replaced by automated robots. In the field of modern logistics transportation, fully automated, efficient, and high-density become the future development. Target. [0003] Usually, in the logistics transportation environment, the working process of the robot is generally as follows: the robot loads the goods at the loading point according to the task order, and then delivers the goods to the destination according to the delivery task corresponding to the task order, and the user picks up the goods. In order to support the mobility of robots, most robots currently use rechargeable batteries as power sources. Due to the limited power store...
