The present application claims priority to Korean Patent Application No. 10-2023-0192115, filed Dec. 27, 2023, the entire contents of which are incorporated herein for all purposes by this reference.
The present disclosure relates to an insert nut fixing device that enables a robot to hold and fix an insert nut.
A plate P supporting a battery cell has an insertion hole H perforated on a side thereof to insert an insert nut I thereto as illustrated in
In this case, the robot fixes the insert nut I by magnetizing the insert nut I to prevent the insert nut I from falling out during movement and an insertion process. However, there is a problem that the rigidity of the insert nut is reduced when the insert nut is made of a magnetizable material.
Therefore, there is an emerging need to develop a technology that is capable of fixing the insert nut in a way other than magnetization.
Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and the present disclosure is intended to propose an insert nut fixing device capable of stably fixing an insert nut without magnetizing the insert nut.
In order to achieve the objective of the present disclosure, there is provided an insert nut fixing device including: a body 100 with a rod shape formed by extending in a longitudinal direction thereof and having an insertion groove 101 formed on a longitudinal edge thereof; and an elastic movement means 200 coupled to the insertion groove 101 to be movable elastically in a vertical direction.
In addition, the elastic movement means 200 may include a holding jaw forming member 210 formed by protruding on an upper side thereof.
In addition, the insertion groove 101 may include: a first insertion groove 101-1 located on a front side of the body 100, and a second insertion groove 101-2 located behind the first insertion groove 101-1, wherein a depth of a second insertion groove 101-2 may be larger than a depth of the first insertion groove 101-1.
In addition, the elastic movement means 200 may include: a front elastic movement means 200A arranged by being spaced apart from a surface of the body 100 having the first insertion groove 101-1; and a rear elastic movement means 200B located behind the front elastic movement means 200A and coupled to a surface of the body 100 having the second insertion groove 101-2.
In addition, the rear elastic movement means 200B may be welded to the body 100.
In addition, the body 100 may include a step portion 102 formed on a front edge thereof.
In addition, the elastic movement means 200 may include: a ball 220 fitted into the insertion groove 101; and an elastic member 230 configured to connect a lower side of the ball 220 and a surface of the insertion groove 101 to each other.
In addition, the body 100 may include an anti-separation rib 103 formed on a front side of the insertion groove 101.
In addition, the holding jaw forming member 210 may include a first member having a hemispherical shape located on an upper side thereof and made of a metal material; and a second member, which is made of rubber or silicone, coupled to a lower flat surface of the first member and connecting the first member and the elastic movement means 200 to each other.
In the insert nut fixing device of the present disclosure, the elastic movement means is inserted into a hole perforated in the center of an insert nut, and the holding jaw forming member is fitted between threads formed on the inner surface of the insert nut so that the insert nut is fixed, thereby enabling the insert nut to be stably fixed without magnetizing the insert nut.
In addition, the step portion is formed on the front side of the body, thereby allowing the insert nut to be constantly fixed in the same position.
Additionally, the anti-separation rib is formed on the front side of the insertion groove, and thus when a robot pulls the insert nut fixing device, the elastic movement means is pulled, and a force is concentrated on a coupling portion of the elastic movement means with the body, thereby preventing the coupling of the body and the elastic movement means from being released.
That is, the anti-separation rib is located in a direction in which the elastic movement means is pulled, thereby limiting the elastic movement means from being pulled with a force exceeding a certain level.
The above and other objectives, features, and other advantages of the present disclosure will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings, in which:
Advantages and features of embodiments of the present disclosure and methods for achieving them will become apparent with reference to the embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below and may be implemented in various different forms. The embodiments are provided only to ensure that the disclosure of the present disclosure is complete and to fully inform those skilled in the art to which the present disclosure belongs of the scope of the present disclosure, and the present disclosure is defined only by the scope of the claims. Throughout the specification, identical reference numerals refer to identical components.
In describing the embodiments of the present disclosure, when it is determined that a detailed description of a known function or configuration may unnecessarily obscure the gist of the present disclosure, the detailed description will be omitted. In addition, terms described below are terms defined in consideration of functions thereof in the embodiments of the present disclosure, and may vary depending on the intention or custom of a user or operator. Therefore, the definitions should be based on contents throughout this specification.
Hereinafter, an insert nut fixing device 1000 according to the present disclosure will be described with reference to the accompanying drawings.
Referring to
To explain in detail, when a longitudinal side of the body 100 is coupled to a robot, and the robot inserts the body 100 into a hole perforated in the center of an insert nut I, the holding jaw forming member 210 is moved into the insertion groove 101 while the elastic movement means 200 is moved downward. When the insertion of the body 100 is completed, the elastic movement means 200 that is moved downward is restored to an original position thereof, and the holding jaw forming member 210 is fitted into a groove formed by threads S formed on an inner surface of the insert nut I, so that the insert nut I is fixed to the insert nut fixing device 1000.
In addition, the insertion groove 101 may include a first insertion groove 101-1 located on a front side of the body 100 and a second insertion groove 101-2 located behind the first insertion groove 101-1, and the elastic movement means 200 may include a front elastic movement means 200A arranged by being spaced apart from a surface of the body 100 having the first insertion groove 101-1, and a rear elastic movement means 200B located behind the front elastic movement means 200A and welded to a surface of the body 100 having the second insertion groove 101-2.
To explain in detail, when the body 100 is inserted into the hole perforated in the center of the insert nut I, the holding jaw forming member 210 is in contact with the side surface of the insert nut I and the elastic movement means 200 is moved downward. The elastic movement means 200, which is moved downward, is moved upward again when the body 100 is completely inserted into the center of the insert nut I, and the holding jaw forming member 210 is fitted into the groove formed between the threads of the insert nut I.
In this case, it is recommended that the holding jaw forming member 210 has an inclined surface M formed on one side in a longitudinal direction thereof so that the elastic movement means 200 is moved downward by a force transmitted when the holding jaw forming member 210 is in contact with the insert nut I.
Additionally, it is recommended that the depth H1 of a gap formed between the front elastic movement means 200A and the first insertion groove 101-1 is equal to the height H2 of the holding jaw forming member 210.
In addition, it is recommended that the depth of the second insertion groove 101-2 is larger than the depth of the first insertion groove 101-1, and thus when the rear elastic movement means 200B, which is formed to protrude downward, is inserted into the second insertion groove 101-2, a contact area between the surface of the second insertion groove 101-2 and the rear elastic movement means 200B increases so that welding between the second insertion groove 101-2 and the rear elastic movement means 200B can be stably performed.
That is, the contact area is maximized by forming a step structure through depth difference.
In addition, it is recommended that the body 100 has a step portion 102 formed on the front edge thereof, and when the body 100 is inserted into and fixed to the hole perforated in the center of the insert nut I, the depth of the body 100 inserted into the insert nut I is always maintained constant.
To explain in detail, the insert nut I is always coupled in a constant form to the insert nut fixing device 1000 of the present disclosure, so that a subsequent insert nut insertion process performed by a robot can be performed stably.
In this case, a step groove 201 corresponding to the step portion 102 may be formed on the elastic movement means 200.
In addition, although not shown in the drawing, the holding jaw forming member 210 includes a first member having a hemispherical shape located on the upper side thereof and made of a metal material, and a second member, which is made of rubber or silicone, coupled to the lower flat surface of the first member and connecting the first member and the elastic movement means 200 to each other. Accordingly, when the robot pulls the insert nut fixing device hard, the second member may be compressed, allowing the first member to be more easily removed from the insert nut.
Referring to
To explain in detail, when the body 100 is inserted into the hole perforated in the center of the insert nut I, the elastic member 230 is compressed and the ball 220 moves downward, and when the insertion is completed, the elastic member 230 is restored and the ball 220 moves upward so that the ball 220 can be fitted into a groove formed between the threads of the insert nut I.
In this case, the elastic member 230 may include various members having high elastic restoring force, and may be a spring in an embodiment, but is not limited thereto.
The present disclosure is not limited to the above-described embodiments, and is broad in the scope of application. Those skilled in the art may make various modifications without departing from the gist of the present disclosure claimed in the claims.
