Description

3D Printer {3D Printer}

The present invention relates to a 3D output device, and more particularly, to a 3D output device for producing an output having a three-dimensional structure.

3D printing technology is a technology for manufacturing an output with a three-dimensional shape. It is a method of laminating and hardening materials with predetermined fluidity and viscosity, such as filaments, to create, manufacture, and process objects, such as cutting and punching tools. It has the advantage that it does not require processing means of

Although 3D printers using this principle are known in the prior art, 3D printers implement a shape by programming, and programming and drawing must be made using a computer, and a three-dimensional shape must be considered on a flat screen, etc. As it requires some expertise, it may be inappropriate for unskilled people or to form creations/products with relatively small shapes.

In order to solve this problem, the preceding Korean Patent Publication No. 10-1906585 discloses a 3D printing pen for manufacturing an electric circuit.

More specifically, the prior literature discloses that the printing means itself for discharging the resin liquid, usually referred to as a filament, may be formed in a shape and size corresponding to a writing instrument such as a pen.

Accordingly, there is an advantage in use that no separate programming is required and an intended shape can be easily output through a manipulation method corresponding to the writing instrument gripping method.

In addition, through the advantage of being able to do this manually, the effect that the user can understand the additive manufacturing concept of 3D printing more intuitively occurs.

However, according to the prior literature, there arises a problem that the advantages cannot be applied to users who are unfamiliar with the holding method of writing instruments, or who are uncomfortable or unable to hold writing instruments, such as infants and people with handicaps.

In addition, even if there is no human defect defect and a person familiar with the writing instrument gripping method uses the writing instrument type printing means disclosed in the preceding document, there is a problem that the work precision is considerably insufficient compared to the programming type 3D printer.

And, FIGS. 7A to 7C are views showing an example of a coupling process between wearing bodies based on the state shown in FIG. 6 .

5, 6, and 7A to 7C, the wearing unit 100 is configured to insert a specific finger for manipulation of the output device, and the wearing body 110 and the first insertion unit 120 ), a connection body 130 , a coupling part 140 , and a body-side rotating shaft member 150 .

At this time, although FIG. 3 shows that the finger drawn into and withdrawn from the wearing unit 100 is the index finger, other fingers may be used according to the user's selection.

The wearable body 110 may be configured as a kind of thimble structure by forming the first inserting part 120 into a structure in which the wearable body 110 is hollow inside.

In addition, as openings communicating both ends of the first inserting part 120 to the outside are formed at both ends of the wearable body 110 , fingers can be drawn in and out of the first inserting part 120 . Thus, the user can insert his or her finger into the wearing body 110 or take it out from the wearing body 110 .

In this case, the width or diameter of the first insertion part 120 may be variously standardized based on various parameters such as the user's age, gender, and body type.

In addition, the wearable body 110 may be made of an elastic material such as rubber, and other elastic materials capable of smoothly performing elastic deformation and elastic restoration in response to bending and unfolding motions of the knuckles may be used. .

Through the elastic deformation and elastic restoration action due to such material selection, even minute movements of the fingers can be naturally reflected in the size and shape deformation of the wearing body 110, so that the ease of use and the sophistication of work can be improved. be able to

In addition, in this case, the user can use the output device product to which the wearable body 110 having an inner hollow width or inner hollow diameter smaller than the thickness of his or her finger by a predetermined size or more.

Accordingly, when the user's finger is inserted into the corresponding worn body 110, the corresponding worn body 110 is elastically deformed in response to the thickness of the user's finger, and its inner width or diameter increases, and then the corresponding worn body 110 ) is elastically restored in the direction that the inner peripheral surface presses the corresponding finger.

Thus, the elastic restoring force acting on the wearable body 110 implements a position fixing action or a slip prevention action for the user's finger, thereby further enhancing the wearing stability.

And, referring to FIG. 4, the wearing body 110 may be provided in plurality, and the wearing body 110 may be continuously coupled to each other by lining up coaxially in a direction corresponding to the length direction of the finger, In addition, they can be easily separated from each other.

Accordingly, the user can adjust the total length of the wearing unit 100 corresponding to the length of his or her finger by adjusting the number of couplings between the wearing body 110, thereby improving compatibility in use.

At this time, in order to implement the above-described coupling and disconnection structure between each wearing body 110 , the connection body 130 , the coupling part 140 , the body-side rotation shaft member 150 for each worn body 110 , etc. This configuration may be, and these configurations may also be formed of an elastic material.

In more detail, the connection body 130 may be formed to extend in pairs on both sides of the front of each wearing body 110 , and the front at this time is based on the state in which the user's finger is inserted into the wearing body 110 . It may mean the direction of the distal end of the corresponding finger, and the rear may be understood as the opposite direction.

In addition, the connection body 130 may be designed to have a semi-circle convex to a semi-elliptical shape having a predetermined curvature in the forward direction.

In addition, each connection body 130 has a moving line corresponding to the length direction of the finger, and the shaft passing portion 131 having a predetermined length to the rear while opening the front of the connection body 130 is formed. In addition, the rear end of the shaft passing portion 131 may have a shaft seating portion 132 extending and incision formed.

In this case, the shaft seating part 132 may have a circular structure symmetrical with respect to the concentric axis of the shaft passing part 131 .

In addition, the diameter size of the shaft seating part 132 may exceed the width or diameter size of the shaft passing part 131 .

In addition, the coupling portion 140 may be formed in a recessed or incised structure from both rear end surfaces of the wearable body 110 toward the front, and the depth of the depression or incision is the width of the connection body 130 . It may correspond to the thickness.

At this time, in the structure of the coupling part 140 , a predetermined curved part is formed so that the connection body 130 provided in the other wearing body 110 located at the rear of the corresponding wearing body 110 is rotatable while in surface contact with it. can be

That is, a rotatable structure may be formed in front of the coupling portion 140 while the front curved portion of the connection body 130 is in surface contact.

In addition, the body-side rotation shaft member 150 may be provided in a cylindrical structure that protrudes toward the longitudinal axis of the wearable body 110 for each coupling portion 140 , and is attached to and inserted into each coupling portion 140 . , may be configured in various ways, such as forming an extension.

In addition, the body-side rotation shaft member 150 may be configured such that the longitudinal axis is coaxial with the concentric axis of the shaft seating part 132 , and accordingly, the body-side rotation shaft member 150 and the shaft seating part 132 . can be provided coaxially corresponding to the axis of the knuckle bending motion.

In addition, a plurality of wearable bodies 110 provided with each other may be coupled to and separated from each other through the connection body 130 and the body-side rotation shaft member 150 provided therein.

More specifically, the connection body 130 of a wearing body 110 enters to the front inner wall of the coupling part 140 of the wearing body 110 located in the front thereof, so that the connection body 130 is the coupling part ( 140), based on the state in which the connection body 130 and the coupling part 140 are in surface contact with each other by being completely impregnated in 140), the body-side rotation shaft member 150 located in the wearing body 110 on the front side is worn on the rear side It may pass through the shaft seating portion 132 of the body 110 .

In this case, the diameter of the body-side rotating shaft member 150 may be greater than or equal to the diameter of the shaft seating portion 132 .

Accordingly, when the body-side rotation shaft member 150 is seated on the shaft seating part 132 , an elastic restoring force is applied to the inner edge of the shaft seating part 132 in the direction of pressing the outer circumferential surface of the body-side rotation shaft member 150 . it will work

Thus, the body-side rotation shaft member 150 may have the effect of preventing position departure and preventing slip corresponding to the above-described elastic restoring force.

To describe the coupling process between the wearing bodies 110 in more detail, first, as shown in FIG. 7a, the body-side rotation shaft member 150 on the side of the wearing body 110 located in the front is positioned at the rear of the wearing body ( 110) enters the shaft passing portion 131 inlet side.

Next, as shown in the order of 7a to 7b, the front worn body 100 side body-side rotation shaft member 150 is a corresponding axis along the longitudinal direction of the rear worn body 100 side shaft passing part 131 It moves in the direction of the shaft seating part 132 located at the inner end of the passing part 131 .

At this time, as mentioned above, since the diameter d1 of the rotation shaft member 150 is larger than the width size w1 of the shaft passing part 131, the front worn body 100 side rotation shaft member 150 is located at the point The width size w2 of the shaft passing part 131 on the rear wearing body 100 side is elastically deformed to a size corresponding to the diameter d1 size of the front wearing body 100 side rotation shaft member 150 .

And, as the body-side rotation shaft member 150 deviates from its position, the width of the shaft passing portion 131 that was elastically deformed is elastically restored to the original size w1.

The repeated action of such elastic deformation and elastic restoration is performed until the rotation shaft member 150 on the front worn body 100 side completely passes through the shaft passage part 131 on the rear worn body 100 side. ) in the entire length section.

Finally, as shown in the order of Figures 7b to 7c, the body-side rotation shaft member 150 on the front worn body 100 side is seated on the rear worn body 100 side shaft seating part 132, thereby providing forward and backward with each other. The coupling between the worn body 110 is completed.

And, even if an external force within a predetermined range acts on the body-side rotating shaft member 150 in the direction of the shaft passing portion 131 , the diameter d1 of the body-side rotating shaft member 150 and the width of the shaft passing portion 131 are An interference phenomenon occurs due to the difference between (w1), so that separation of the body-side rotating shaft member 150 can be prevented.

In addition, in the same manner, various numbers of the worn body 110 can be sequentially lined up and coupled to each other.

In addition, the wearing body 110 has a length structure corresponding to a part of the length direction of the finger, and the body-side rotation shaft member 150 has a rotation shaft structure corresponding to the knurl movement of the finger in the wearing body 110. Accordingly, a rotational action corresponding to the bending and unfolding motions of the knuckles can occur between the wearable bodies 110 connected to each other with the body-side rotation shaft member 150 as an axis.

Therefore, in the wearing unit 100, bending and unfolding actions corresponding to knuckle movements can be generated at each position corresponding to each of the body-side rotation shaft members 150 provided between each of the plurality of wearing bodies 100. will be.

In addition, as the above-described processes are performed in the reverse order through FIGS. 7A to 7C , each wearing body 110 may be separated from each other, and for this purpose, an external force exceeding the elastic force of the material used for manufacturing the connecting body 130 may be required. have.

In addition, the body-side rotating shaft member 150 may be formed of an elastic material, and may also be formed in a protruding structure extending from the coupling portion 140, and through unification between the manufacturing material and the coupling relationship, manufacturing cost, manufacturing Man-hours and the like can be reduced.

Alternatively, the body-side rotation shaft member 150 may be formed of a separate rigid material, and the rigid material at this time is elastic deformation or compression deformation, etc. It can be understood as a material in which various external deformations hardly occur.

Through securing the rigidity of the body-side rotation shaft member 150 as described above, the body-side rotation shaft member 150 can maintain its original shape, so that the rotation operation using the advantage of the circular shape can proceed smoothly.

In this case, the body-side rotation shaft member 150 may be configured to be inserted or attached to the coupling portion 140 side.

In addition, in the connection body 130, elastic deformation and elastic restoration can be smoothly performed in the process in which the rotating shaft member 150 passes through the shaft passing part 131 and is seated on the shaft seating part 132 and the reverse order of the elastic material. can be manufactured with
