Description

Technical Field

[0001] The present invention relates to the technical field of robots, and particularly to a robot alignment charging device and an alignment charging method. Background Art

[0002] With the rapid development of robot technology, due to its advantages such as simple operation, high efficiency, and low cost, robots have great application value and development prospects. To ensure the normal operation of robots, it is often necessary to charge robots from time to time and continuously.

[0003] For existing robot charging, some relatively precise image recognition is required to align with the charging port. However, precise image recognition has relatively high requirements for cameras and algorithms, increasing the R & D cost of robots and being unfavorable for the popularization and use of robots. Moreover, if the positioning of the robot is inaccurate, when moving to align for charging, the electrodes on the robot and the electrodes on the charging pile will not be well docked, which will inevitably affect the charging effect and is also unfavorable for the maintenance of the equipment. Summary of the Invention

[0004] To solve the above technical problems, the present invention designs a robot alignment charging device that uses a pure physical alignment method for charging to effectively reduce the alignment charging cost of the robot.

[0005] The specific solutions are as follows:

[0006] One of the purposes of the present invention is to provide a robot alignment charging device, including a robot charging head and a charging pile body. The robot charging head is inserted into the charging pile body for charging. The robot charging head is provided with a first electrode, and the first electrode includes a first male electrode and a first female electrode. The charging pile body is provided with a second electrode, and the second electrode includes a second male electrode and a second female electrode. During charging, the first male electrode is in contact conduction with the second female electrode, and the first female electrode is in contact conduction with the second male electrode; the robot charging head is provided with a conical guiding portion in the direction facing the charging pile body, and the charging pile body is provided with a concave inverted conical limiting portion in the direction facing the robot charging head, and the shape and size of the inverted conical limiting portion match those of the conical guiding portion, so that the conical guiding portion can be inserted into the inverted conical limiting portion to achieve the contact conduction between the first electrode and the second electrode.

[0007] Further, the opening angle of the conical guiding portion is significantly larger than the opening angle of the inverted conical limiting portion.

[0008] Further, the conical guiding portion is a conical mechanism symmetrically arranged on both sides of the first electrode.

[0009] Further, an elastic material is provided inside the conical guiding portion, and the conical guiding portion is wrapped by soft leather.

[0010] Further, the elastic material is sponge.

[0011] Further, the conical guiding portion is detachable.

[0012] Further, the inverted conical limiting portion is an inverted conical limiting mechanism provided in the recess of the charging pile body, and the second electrode is provided at the center of the bottom of the inverted conical limiting mechanism.

[0013] Further, the camera of the robot is disposed on a vertical line with the centers of the first male electrode and the first female electrode.

[0014] Another object of the present invention is to provide an alignment charging method for the above-mentioned robot alignment charging device, including the following steps:

[0015] (1) When the robot needs to charge, the robot moves so that the second electrode is located at the vertical center of the camera, and the robot moves straight forward;

[0016] (2) When the conical guiding portion of the robot touches the inverted conical limiting portion of the charging pile body, since the opening angle of the conical guiding portion is larger than that of the inverted conical limiting portion, the conical guiding portion is squeezed and shrunk towards the middle, and the robot keeps moving straight forward;

[0017] (3) When the first electrode and the second electrode are facing each other, the robot continues to move straight forward, and the first electrode and the second electrode are in contact and conduct electricity to start charging;

[0018] When the first electrode and the second electrode are not facing each other, that is, the robot is tilted, the conical guiding portion of the robot will receive a greater reaction force from the elastic material on the tilted side, thereby correcting the forward route, and finally making the first electrode and the second electrode face each other. The robot continues to move forward, the first electrode and the second electrode are in contact and conduct electricity to start charging.

[0019] Beneficial effects:

[0020] 1. The present invention adopts the design of inserting the conical guiding portion into the inverted conical limiting portion, which can achieve alignment and calibration when the robot moves forward to ensure the straight forward movement of the robot, directly close the power connection, and does not require repeated adjustment.

[0021] 2. The present invention is easy to maintain. The conical guiding portion that may be worn can be replaced, with low cost and is suitable for popularization and use. Description of the drawings

The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment 1:

[0030] As a preferred solution of the present invention, the opening angle of the conical guiding part 5 is significantly larger than that of the inverted conical limiting part 6, so that the conical guiding part 5 will be squeezed by the inverted conical limiting part 6 and shrink towards the middle, thereby adjusting and aligning the moving trajectory of the robot.

Moreover, the conical guiding portion 5 is wrapped with wear-resistant soft leather to increase the service life.

[0032] In addition, after long-term use, the conical guiding portion 5 will more or less deform, resulting in inaccurate alignment. To avoid this situation, the conical guiding portion 5 of the present invention is detachably connected, and after being used for a period of time, the conical guiding portion 5 can be replaced.

[0033] As another preferred embodiment of the present invention, the inverted conical limiting portion 6 is an inverted conical limiting mechanism arranged in the depression of the charging pile body 2, and the second electrode 4 is arranged at the center of the bottom of the inverted conical limiting mechanism.

When the robot needs to charge, the robot moves so that the second electrode 4 is located at the vertical center of the camera. When the robot moves straight along this vertical line, alignment charging can be achieved.

[0038] (2) When the conical guiding portion of the robot touches the inverted conical limiting portion of the charging pile body, since the opening angle of the conical guiding portion is larger than that of the inverted conical limiting portion, the conical guiding portion is squeezed and shrinks towards the middle, and the robot keeps moving straight forward;

[0039] (3) When the first electrode and the second electrode are facing each other, the robot continues to move straight forward, and the first electrode and the second electrode come into contact and conduct electricity to start charging;

[0040] When the first electrode and the second electrode are not facing each other, that is, the robot is tilted, the conical guiding portion of the robot will receive a greater reaction force from the elastic material on the tilted side, thereby correcting the forward route, finally making the first electrode and the second electrode face each other, the robot continues to move forward, and the first electrode and the second electrode come into contact and conduct electricity to start charging.

[0041] The present invention can achieve alignment and calibration when the robot moves forward, so as to ensure the straight forward movement of the robot, directly close the power connection, and there is no need for repeated adjustment.
