Description

Block-type joint module for multi-joint robots

[0001] The present invention relates to a block-type joint module for a multi-joint robot, and more specifically, to a block-type joint module for a multi-joint robot that facilitates the addition or modification of necessary joints based on the block-type joint module, facilitates electrical connection to the block-type joint, and eliminates the exposure of wires to the outside.

[0002] A multi-joint robot is a robot capable of performing movements similar to human motion through multiple joints. For example, a finger robot, which is shaped like a finger to enable gripping of an object, forms parts such as finger joints by connecting multiple segments. The parts corresponding to the finger joints must be capable of rotational movement relative to one another; conventionally, each segment is connected by a wire, and the rotational movement of the segment is controlled by pulling or tightening the wire. Conventional finger robots have the disadvantage that multiple wires must be arranged to connect each segment, and the repetitive winding and dewinding of the wires reduces the lifespan of the finger robot. Furthermore, since the electrical connection of each segment is maintained by wires exposed to the outside, interference with other structures during the installation and movement of the wires becomes a problem.

[0003] The present invention has been devised to solve the requirements described above, and aims to provide a block-type joint module for a multi-joint robot that facilitates the addition or modification of necessary joints based on a block-type joint module, facilitates electrical connection to the block-type joint, and eliminates the exposure of wires to the outside.

[0004] A block-type joint module for a multi-joint robot according to an embodiment of the present invention is characterized by having a first part having a first connection terminal electrically connected to one side, a second part having a second connection terminal electrically connected to one side and arranged to rotate relative to the first part, wherein the first connection terminal and the second connection terminal are electrically connected through the first part and the interior of the first part, and the first and second parts are combined with each other and can be electrically connected to a third part and a fourth part, respectively, through the first connection terminal and the second connection terminal.

[0005] Additionally, it is preferable that the first connecting terminal is formed on a first coupling surface portion that is flatly formed on the first part, and the second connecting terminal is formed on a second coupling surface portion that is flatly formed on the second part.

[0006] In addition, it is preferable that the first part is provided with a first exposed groove that exposes the first connection terminal, and the second part is provided with a second exposed groove that exposes the second connection terminal.

[0007] In addition, it is preferable that the first connection terminal and the second connection terminal each include a plurality of pin portions that are electrically energized.

[0008] Additionally, it is preferable that the extension block is connected to the first part or the second part to extend the length of the joint, wherein the extension block comprises: a first body part; a third connection terminal provided for electrical connection on one side of the first body part; a fourth connection terminal provided for electrical connection on the other side of the first body part facing the third connection terminal; an insertion part into which the first part or the second part is inserted; and a space part provided between the third and fourth connection terminals to provide a space for electrically connecting the third connection terminal and the fourth connection terminal.

[0009] Additionally, the first connecting block comprises a second body part having a fifth connecting surface portion having a fifth connecting terminal formed thereon to which the first or second part is joined and electrically connected, and a sixth connecting surface portion having a sixth connecting terminal formed thereon to which the first or second part is joined and electrically connected, wherein the direction of the surface where the fifth connecting surface portion is formed and the direction of the surface where the sixth connecting surface portion is formed are formed in different directions and intersect each other.

[0010] Additionally, it is preferable that the first connecting block has the fifth connecting terminal and the sixth connecting terminal electrically connected inside the second body part, and that a first fastening plate part protruding from the second body part is connected to a predetermined other multi-joint joint.

[0011] Additionally, it is preferable to include a second connecting block comprising a third body part having a seventh connecting surface portion formed on the upper side to which the first part or the second part is joined and electrically connected, and an eighth connecting surface portion formed on the lower side to which the first part or the second part is joined and electrically connected, wherein the seventh connecting surface portion and the eighth connecting surface portion are parallel to each other, and the seventh connecting terminal and the eighth connecting terminal are electrically connected inside the third body part, and either the seventh connecting surface portion or the eighth connecting surface portion is formed by protruding from the edge to form a second fastening plate portion to which a predetermined other multi-joint joint is connected, and the predetermined other multi-joint joint is connected in the same direction as the direction in which the seventh and eighth connecting surfaces are formed.

[0012] The block-type joint module for a multi-joint robot according to the present invention allows for easy addition or modification of necessary joints based on the block-type joint module. That is, a multi-joint robot can be completed by connecting other parts to the joint module as a single unit. This provides the effect of offering a modularized multi-joint robot in a completely new and groundbreaking manner compared to conventional methods.

[0013] In addition, according to an embodiment of the present invention, electrical connection is facilitated by using a connection terminal provided in a block-type joint, and the wires are excluded from external exposure, thereby providing the effect of fundamentally preventing the wires from interfering with other structures.

Meanwhile, referring to FIG. 1, the fingertip module of the finger module may be electrically connected to the first part (10), and the fingertip module may also be the third part or the fourth part connected to the joint module (100) according to the embodiment of the present invention.

[0087]

[0088] Thus, the block-type joint module (100) for a multi-joint robot according to the present invention can form a multi-joint unit having a predetermined number of joints by connecting additional joints using the block-type joint module (100) as a basic unit module. For example, in the case of a finger module (1000), the length or the number of joint joints can be assembled in a desired manner, and the direction of the joints can be easily changed to realize an optimal multi-joint robot. In addition, the joint module (100) and the joints coupled thereto are electrically connected by a connection terminal and are not wired externally, thereby providing the effect of excluding interference with other structures.
