At this time, the material, diameter, overall shape, and function of the outer ring 110 may be applied to various embodiments of the outer ring used in the existing smart ring, so a detailed description thereof will be omitted.

However, the outer ring 110 of the present invention is manufactured by press working, and in a manufacturing method and a method of coupling and fixing the inner ring 120 to be described later, it can be differentiated from the existing smart ring, about it will be described later.

Next, the inner ring 120 is inserted and coupled to the inside of the outer ring 110 so that a user's finger can be inserted and contacted therein, and the PCB assembly 130 is formed on the outer surface of the inner ring 120 .

In addition, the PCB assembly 130 may be provided with a battery 134 used as a power source of the smart ring 100 , the PCB assembly 130 including the battery 134 is the outer peripheral surface of the inner ring 120 . Since it is combined in a form surrounding the battery 134 and PCB of all flexible (flexible) material can be used.

Next, the display window 140 serves as a window through which the user can visually check the measurement results or the corresponding state of the sensors provided in the PCB assembly 130 , and is formed in the outer ring 110 . It may be press-coupled to the display window coupler 112 .

In this case, the shape and number of the display windows 140 may vary as needed, and the shape and number of the display window coupling units 112 formed on the outer ring 110 may vary depending on the shape and number of the display windows 140 . of course there is

In addition, as the display window 140 , a display means in which a display module is integrally formed for displaying measurement results of sensors provided in the PCB assembly 130 or a corresponding state thereof may be used.

The configuration of the smart ring 100 including the outer ring 110 , the inner ring 120 , the PCB assembly 130 and the display window 140 as described above is already known in the prior art, etc. In the description, the characteristic configurations of the smart ring 100 according to the present invention will be mainly described.

First, the outer ring 110 is manufactured by press working, and then may be finished by spinning. For more accurate spinning, the inner surface of the outer ring 110 manufactured by press working has a machining groove ( 114) can be formed.

That is, the machining groove 114 is formed on the inner surface of the outer ring 110 in the circumferential direction, and at the same time as a spinning operation, that is, a bending portion forming operation, which will be described later, a spinning operation, that is, a bending portion forming operation can be made more easily, and a processing error It can play a role in reducing the risk of occurrence.

In addition, a fixing groove 116 may be formed on the inner surface of the outer ring 110 , in which a fixing part 136 installed on the outer surface of the PCB assembly 130 is inserted and coupled to the fixing groove 116 . can

That is, as shown in FIG. 3 , the fixing groove 116 and the fixing part 136 have a coupling configuration of the inner ring 120 inserted into the inner side of the outer ring 110 and the PCB assembly 130 to the outer ring. In order to be coupled more firmly with the 110 , the fixing part 136 may include a masking part 136a , a spring member 136b and a fixing member 136c .

In more detail, the masking part 136a is installed on the outer surface of the PCB assembly 130 and may be made of a non-conductive material attached to a portion where a sensor or circuit is not installed or formed.

The masking part 136a may be made of an elastic material, and an insertion groove into which the spring member 136b is inserted may be formed at an upper end thereof.

Next, the spring member 136b is inserted and coupled to the inside of the insertion groove formed in the masking part 136a to fix and support the lower portion of the fixing member 136c, and a leaf spring may be used.

In addition, the fixing member 136c is configured to be fixedly installed on the upper end of the spring member 136b, and when the coupling configuration of the inner ring 120 and the PCB assembly 130 is coupled to the inside of the outer ring 110, the outer side It is inserted and coupled to the inside of the fixing groove 116 formed on the inner surface of the ring 110 .

That is, after inserting and coupling the coupling configuration of the inner ring 120 and the PCB assembly 130 into the outer ring 110 by a method such as interference fitting, the inner ring 120 is rotated in the circumferential direction to thereby rotate the spring member When the fixing member 136c connected to the masking part 136a by the 136b is positioned in the fixing groove 116 formed in the outer ring 110, the fixing member 136c is formed by the restoring force of the spring member 136b. Since the fixing groove 116 is inserted and fixed to the inside, the coupling configuration between the inner ring 120 and the PCB assembly 130 can no longer rotate and the position inside the outer ring 110 can be fixed.

At this time, a guide groove 118 having a lower depth than the fixing groove 116 is formed in the circumferential direction of one side of the fixing groove 116 of the outer ring 110 to combine the inner ring 120 with the PCB assembly 130 . When the configuration is inserted into the inside of the outer ring 110, the fixing member 136c is positioned on the guide groove 118, so that the operation of positioning the coupling configuration of the inner ring 120 and the PCB assembly 130 is more It may be configured to be easily accomplished.

In addition to being there, it is possible to show the advantage of preventing deformation or position movement in the assembled state.

After inserting and coupling the coupling configuration of the inner ring 120 and the PCB assembly 130 to the inside of the outer ring 110 as described above, the open end of the outer ring 110 without a step is processed by spinning processing.

On the other hand, the manufacturing method of the smart ring according to the present invention is a method of manufacturing the smart ring 100 according to the present invention configured as described above, and the configuration is as shown in FIG. 4 , largely in the outer ring manufacturing step (S10). ) , a display window fixing step (S20), a PCB assembly bonding step (S30) and a spinning processing step (S40).

First, the outer ring manufacturing step (S10) is a step of manufacturing the outer ring 110 forming the outer shape of the smart ring 100 by press working, a drawing processing step (S11), a piercing processing step (S12) and It may include a punching processing step (S13).

In more detail, the drawing processing step (S11) is a step of processing a plate-shaped material into a concave shape with a closed lower end through drawing processing, as shown in FIG. It can be processed by setting the pressure so that the outer ring 110 can be formed.

Next, the piercing processing step (S12) is a process of cutting the closed portion of the material of the concave shape in which the drawing processing is completed, the lower surface is closed through piercing processing, and when the piercing processing is completed, a step is formed on one side A ring-shaped outer ring 110 is manufactured.

Next, the punching processing step (S13) is a process of forming the display window coupling portion 112 by punching processing on the side of the material processed into a ring shape. As described above, the display window 140 used The shape and number of punched parts may vary according to the shape and number.

On the other hand, the outer ring manufacturing step (S10) may further include a machining groove forming step (S14) and a fixing groove forming step (S15). In the process of forming the machining groove 114 in the circumferential direction on the open inner surface without the step of 110), the machining groove 114 makes it easier to form a bent part in the spinning processing step (S40) to be described later. At the same time, it can play a role in reducing the risk of occurrence of machining errors.

Next, in the fixing groove forming step (S15), the fixing member 136c of the fixing part 136 installed on the outer surface of the PCB assembly 130 is inserted into the inner surface of the outer ring 110 that is similarly completed up to the punching process. In the process of forming the fixing groove 116, it may be formed in the same size and shape as the fixing member 136c.

At this time, in the fixing groove forming step (S15), in the circumferential direction of one side of the fixing groove 116, a guide groove 118 having a shallower depth than the fixing groove 116 may be formed. is a configuration for allowing the PCB assembly 130 inserted into the inner side of the outer ring 110 to be positioned in the correct position, as described above.

Next, the display window fixing step (S20) is a process for fixing the display window 140 to the display window coupling part 112 formed on the outer ring 110 by punching, and the display window 140 is compressed using an adhesive means. It may be fixedly installed to the display window coupling unit 112 by a method such as the one shown in FIG.

Next, in the PCB assembly coupling step (S30), the PCB assembly 130 in which the sensor unit 132 and the battery 134 are integrally installed on the outer circumferential surface of the inner ring 120, that is, the recessed portion 122 is integrated. In the process of coupling with a flexible type PCB assembly 130 in a state in which the sensor cap 125 is coupled to the sensor cap coupling part 124 formed in the inner ring 120, the outer circumferential surface of the recessed part 122 is wrapped. After coupling in the form or coupling the flexible type PCB assembly 130 so as to surround the outer circumferential surface of the concave portion 122 , the sensor cap 125 is attached to the sensor cap coupling portion 124 formed in the inner ring 120 . may be coupled, and the sensor cap 125 may be made of an insulating material.

At this time, in the PCB assembly coupling step (S30), a fixing part inserted and coupled to the fixing groove 116 formed in the outer ring 110 in a portion of the outer surface of the PCB assembly 130 to which the sensor part 132 is not coupled ( 136), the fixing part 136 may include a masking part 136a, a spring member 136b, and a fixing member 136c as described above.

That is, in a state in which a masking part 136a made of an elastic material having a predetermined thickness is adhered to a part of the outer surface of the PCB assembly 130 to which the sensor part 132 is not coupled, on the upper portion of the masking part 136a. The spring member 136b is integrally coupled.

At this time, in order to minimize the increase in the overall thickness of the fixing part 136, it is preferable to use a spring in the form of a leaf spring as the spring member 136b.

Next, the installation process of the fixing part 136 can be completed by fixing and installing the thin plate-shaped fixing member 136c on the upper end of the spring member 136b.

Next, the spinning processing step (S40) is a process of forming a bent portion by spinning processing at the open end of the outer ring 110, the inner ring 120 and the PCB assembly combined in the PCB assembly bonding step (S30) The inner ring inserted into the inner ring of the outer ring 110 by bending the open end of the outer ring 110 inward by spinning in a state in which the coupling configuration of the outer ring 110 is inserted into the inner side of the outer ring 110 . It is possible to prevent separation of the combined configuration of the 120 and the PCB assembly 130 .

More specifically, in the spinning processing step (S40), first, the combined configuration of the inner ring 120 and the PCB assembly 130 is inserted into the outer ring 110, and the outer surface of the PCB assembly 130 is inserted. The fixing member 136c of the installed fixing part 136 is inserted until it is seated in the guide groove 118 formed on the inner surface of the outer ring 110 .

When the coupling configuration of the inner ring 120 and the PCB assembly 130 is rotated in the circumferential direction in a state in which the fixing member 136c is seated in the guide groove 118, the fixing member 136c moves the guide groove 118 in the circumferential direction. When the fixing member 136c is positioned above the fixing groove 116 formed on the inner surface of the outer ring 110, the restoring force of the spring member 136b located below the fixing member 136c As the fixing member 136c is inserted and coupled to the inside of the fixing groove 116 by this, the coupling configuration of the inner ring 120 and the PCB assembly 130 is in a state that can no longer be moved, so that the outer ring 110 is coupled inside. This is done.

As described above, as shown in FIG. 6 in a state in which the coupling configuration of the inner ring 120 and the PCB assembly 130 is fixedly installed inside the outer ring 110, one side of the outer ring 110 using a spinning device The end is bent in the inner, that is, the center direction of the outer ring 110, and the spinning operation can be made more accurately and easily by the machining groove 114 formed on the inner surface of the outer ring 110.

When the spinning processing step (S40) is completed, the manufacturing of the smart ring 100 in the form shown in FIG. 1 is completed, and the outer ring 110 in the state in which the inner ring 120 is coupled is compressed and fixed as needed. The compression step (S50) may be additionally performed so that the coupling configuration of the outer ring 110 and the inner ring 120 is more firmly maintained.

In addition, although not shown, before performing the spinning processing step (S40), that is, before inserting the coupling configuration of the inner ring 120 and the PCB assembly 130 into the outer ring 110, the outer ring 110 ) may further include the step of applying a waterproofing adhesive containing an epoxy (epoxy) to the inner surface.
