Description

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional printer having an automatic adhesive application device for fixing an output,

The present invention relates to a three-dimensional printer having an automatic pressure-sensitive adhesive application device for fixing an output, and more particularly, to a three-dimensional printer having a pressure- To a three-dimensional printer having an automatic pressure-sensitive adhesive application device for fixing an output to provide an apparatus and a method for applying a pressure-sensitive adhesive to an output bed.

Recently, three-dimensional printing technology has been attracting attention in the prototype development stage or small quantity production of various kinds of products at the prototype development stage.

3D printing is performed by analyzing the three-dimensional shape of an object through a three-dimensional graphic design program and generating a combination of two-dimensional cross-sectional shape data. Then, raw materials such as ABS and PLA It is a technique of forming a three-dimensional shape of an object by forming it on an output bed by various methods.

In the three-dimensional printing, there are a FDM (Fused Deposition Modeling) method or a FFF (Fused Filament Fabrication) method in which a raw material is extruded and sequentially laminated on an output bed to realize a three-dimensional shape. The powder is melted with a high- There are various SLS (Selective Laser Sintering) systems for realizing a three-dimensional shape, and SLA (Stereolithography Apparatus) systems for projecting a laser beam into a water tank containing a liquid photocurable resin.

A three-dimensional printer using the FDM method or the FFF method, which is a conventional laminate shaping method, uses a method of directly molding a raw material on an output bed and molding it. However, when adhesion between an output bed and an output material is poor, In most cases, the output quality is seriously affected, such as failing to separate the output during the process, or preventing the deformation of the printout due to lack of adhesion during the process of shrinking the printout. Therefore, prior to the use of the conventional three-dimensional printer of the laminate molding type, it is common that a user uses a pressure-sensitive adhesive such as a heat-resistant tape or a glue on the output bed as an output bed before outputting, Various methods have been proposed to increase the fixing power of the output and output beds, such as corroding the upper part of the output bed or performing a separate post-treatment as in the US patent 2005-0173855.

However, since the post-treatment of the output bed described above is not easy to provide fixing force for deforming or separating the output, and since it is recommended to use one time like the heat-resistant tape, it is not easy to use in terms of maintenance cost of the user, Separate adhesive such as heat-resistant tape or paste on the bed has excellent fixing power, but there is inconvenience that the user has to work every time when outputting.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide an apparatus for automatically applying an adhesive to an output bed and an output bed.

Another object of the present invention is to provide a device for managing the deterioration of the pressure-sensitive adhesive in the above process.

A further object of the present invention is to provide a user with convenience by reducing the excessive waste of the pressure-sensitive adhesive by calculating and applying the application area of the pressure-sensitive adhesive in accordance with the output size in the process described above.

As means for solving the above-mentioned technical problem,

The adhesive unit is provided on the side surface of the output nozzle unit, the adhesive is applied to the adhesive unit before the output operation, and then the adhesive is applied to provide an adhesive force between the output bed and the output.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly explain the present invention, parts not related to the description are omitted.

Furthermore, when a part is referred to as being "comprising" or "comprising" an element, it is understood that it may include other elements as well, without excluding other elements unless specifically stated otherwise.

Hereinafter, a three-dimensional printer method using a solid adhesive will be described as an example. However, the pressure-sensitive adhesive of the present invention is not limited to a solid pressure-sensitive adhesive, and it is obvious that the pressure-sensitive adhesive of the present invention can be used in a three-dimensional printer using liquid pressure-sensitive adhesive or other fluid pressure-sensitive adhesive in various modified forms.

1 is a configuration diagram according to an embodiment of the present invention.

Referring to FIG. 1, a three-dimensional printer according to the present invention includes a processor (not shown), an output nozzle unit 300, a sticking unit 100, and a mounting unit 200, The unit 300 includes an output nozzle 310, adhesive application gears 330 and 331 and an adhesive unit fixed electromagnet 350. The adhesive unit 100 includes a permanent magnet 150, an adhesive 110, Unit fixing grooves 140 and adhesive unit adhering gears 120 and 121. The mounting unit 200 includes an adhesive fixing unit 240, an adhesive fixing unit holder 210, and a permanent magnet 250 .

5 is a configuration diagram according to an embodiment of the present invention.

Referring to FIG. 5, the present invention further includes a driving unit and a display unit. The driving unit moves the output unit in left and right and up and down directions, and the display unit plays the same role as a general three-dimensional printer showing the operation and other states of the current three-dimensional printer.

When the user turns on the three-dimensional printer and issues an operation command, the output nozzle unit 300 moves to the position designated in the memory and starts preheating to raise the temperature around the output nozzle 310 to melt the material. A strong current is flowed through the adhesive unit fixing electromagnet 350 provided in the output nozzle unit 300 of the present invention so that the adhesive unit 100 is moved from the mounting unit 200 to the output nozzle unit 300, . At this time, the adhesive fixing unit 240 for fixing the adhesive unit fixing groove 140 and protecting the adhesive 110 moves the adhesive unit 100 to the output nozzle unit 300, Rotate and separate.

The output bed unit (not shown) is lowered by the height difference between the output nozzle 310 and the adhesive unit 100 in order to apply the adhesive 110 when the application of the adhesive 110 is applied to the processor. The descending length may vary depending on the kind of the adhesive 110, and can be manually changed by setting in the process of the 3D printer every time the adhesive 110 is changed.

When the output bed unit (not shown) is lowered, the output nozzle unit 300 moves so that the pressure sensitive adhesive 110 is directly applied to the output bed. At this time, the processor of the three-dimensional printer recognizes the cross-sectional area of the output currently in the output standby state, and applies the adhesive 110 to the output bed based on the layer having the largest cross-sectional area. If the current setting is the economizer mode, the pressure sensitive adhesive 110 is applied to the output bed based on the lowest cross-sectional area. When the area to be coated with the adhesive 110 is calculated, the calculated area is shifted by the distance corresponding to the center distance between the output nozzle 310 and the adhesive unit 100 to set the movement path of the output nozzle unit 300. This is because the actual moving unit is not the adhesive unit 100 but the output nozzle unit 300. [

The application of the adhesive 110 may be performed by pushing the adhesive unit 100 in the direction of the output unit so as to smoothly apply the adhesive 110 when the output nozzle unit 300 moves along the movement path for adhesion of the output nozzle unit 300 There is a need. Figs. 8 and 9 are diagrams showing the configuration of the adhesive application gears 330 and 331 provided to achieve the above-mentioned object.

8 is a method of applying the adhesive 110 using the rack gear 120 and the pinion gear 330. When the adhesive application pinion gear 330 installed on the output nozzle unit 300 rotates, The adhesive rack unit 120 fixed to the adhesive rack 120 receives a force to move the adhesive unit 100 toward the lower end. As a result, the adhesive unit 100 pulls the adhesive unit 100 toward the output bed. When the adhesive unit 100 is pulled toward the output bed, the adhesive 110 is brought into close contact with the output bed, and in this state, the movement path for adhesion is moved.

9 shows a method of applying the adhesive 110 using only gears without members. When the adhesive application gear 331 provided on the output nozzle unit 300 rotates, the adhesive unit adhering gears The shaft fixing the adhesive 110 together with the ball screw 121 rotates and the ball screw 122 coupled to the adhesive unit 100 rotates to move in the direction to widen the gap between the gears, And to push toward the output bed. Also in this case, the adhesive 110 is brought into close contact with the output bed.

When the output nozzle unit 300 is moved to apply the set cross-sectional area, the adhesive application gears 330 and 331 are rotated in opposite directions to move the adhesive unit 100 to an initial height, Is initially moved to an initial position stored in the memory to which the adhesive unit 100 was coupled. When the movement of the output nozzle unit 300 is completed, the output bed unit (not shown) is raised again by a height that is lowered to apply the adhesive 110. The lower end portion of the adhesive unit 100 pushes the surface of the adhesive fixing unit 240 connected to the adhesive fixing unit holder 210 in the process of moving to the initial position, (240) rotates and engages with the adhesive unit fixing groove (140). When the adhesive fixing unit 240 is coupled to the adhesive unit fixing groove 140, the current flowing through the adhesive unit fixing electromagnet 350 of the output nozzle unit 300 is cut off and the output nozzle unit 300 and the adhesive unit 100, . The adhesive unit 100 moves to and engages with the mounting unit 200 when the bonding force between the adhesive unit 100 and the mounting unit 200 becomes stronger than the bonding force between the output nozzle unit 300 and the adhesive unit 100. [ When the separation of the output nozzle unit 300 and the adhesive unit 100 is completed, the normal output of the three-dimensional printer is started.

The foregoing has shown and described specific embodiments. However, it should be understood that the present invention is not limited to the above-described embodiment, and various changes and modifications may be made without departing from the technical idea of the present invention described in the following claims .
