[0042] Fig. 1 is a drawing showing a coating device (1000) according to embodiments. More specifically, Fig. 1 shows a coating device (1000) and an object (10) to which a high-viscosity liquid is applied by the coating device (1000).
[0043] Typically, heat-generating components such as CPUs and memory are equipped with a separate heat spreader (heat dissipation device) to dissipate heat from the components. Here, a thermal interface material (TIM) paste capable of heat transfer can be used as a medium for attaching the heat spreader. While such TIM paste can be manufactured by mixing alumina, wax, solvents, and the like, it is clear that the invention is not limited thereto, and that various other undisclosed examples of such mixtures may exist.
[0044] Referring to FIG. 1, a coating device (1000) according to embodiments can apply a high-viscosity liquid, such as TIM paste or thermal grease, to an application area of a target object (10). At this time, the target object (10) may correspond to an electronic element that generates heat, and may correspond, for example, to a printed circuit board (PCB) on which electronic components (11) are mounted.

[0076] As described in FIGS. 2 and 3, the application device (1000) according to the embodiments can simultaneously apply a high-viscosity liquid through a plurality of nozzle units (300) positioned corresponding to each application area. In other words, referring also to FIG. 4, the first nozzle unit (301) to the seventh nozzle unit (307) can simultaneously apply a high-viscosity liquid to each corresponding application area.
[0077] The application device (1000) according to the embodiments can determine the length or diameter of a plurality of second flow pipes (220) and third flow pipes (230) that are respectively connected so that a plurality of nozzle units (300) can apply high-viscosity liquids simultaneously. More specifically, the length or diameter of a plurality of second flow pipes (220) and third flow pipes (230) that are respectively connected so that a plurality of nozzle units (300) can apply high-viscosity liquids simultaneously can be determined according to the cross-sectional area or arrangement position of the plurality of nozzle units (300).
[0078] First, since the larger the cross-sectional area of the nozzle unit (300), the larger the amount of high-viscosity liquid to be applied, the larger the inner diameter of the connected second flow pipe (220) or third flow pipe (230) may be. For example, as illustrated in FIG. 4, since the cross-sectional area of the sixth nozzle unit (306) among the first to seventh nozzle units (301-307) is the largest, the inner diameter of the second-sixth flow pipe (226) connected to the sixth nozzle unit (306) may be formed to be the largest. Alternatively, as illustrated in FIG. 4, since the cross-sectional area of the fourth nozzle unit (304) among the first to seventh nozzle units (301-307) is the smallest, the inner diameter of the second-fourth flow pipe (224) connected to the fourth nozzle unit (304) may be formed to be the largest.
[0079] Accordingly, the application device (1000) according to the embodiments can be designed so that all nozzle parts (300) can apply high-viscosity liquid simultaneously by designing the inner diameter of the second flow pipe (220) or the third flow pipe (230) connected to each nozzle part (300) differently depending on the cross-sectional area size of the nozzle part (300). Therefore, the application device (1000) according to the embodiments has the effect of being able to apply high-viscosity liquid to the target object (10) in one shot.
[0080] Alternatively, the farther the nozzle unit (300) is arranged from the first flow pipe (210), the longer the travel time of the high-viscosity liquid, and thus the length of the connected second flow pipe (220) or third flow pipe (230) may be formed to be longer. For example, as illustrated in FIG. 4, the arrangement position of the sixth nozzle unit (306) among the first to seventh nozzle units (301-307) may be the farthest from the first flow pipe (210), and thus the length of the second to sixth flow pipe (226) connected to the sixth nozzle unit (306) may be formed to be the longest. Alternatively, as illustrated in FIG. 4, the arrangement position of the fifth nozzle unit (305) among the first to seventh nozzle units (301-307) may be the closest from the first flow pipe (210), and thus the length of the second to fifth flow pipe (225) connected to the fifth nozzle unit (305) may be formed to be the shortest.
[0081] Accordingly, the application device (1000) according to the embodiments can be designed so that all nozzle units (300) can apply high-viscosity liquid simultaneously by designing the length of the second flow pipe (220) or the third flow pipe (230) connected to each nozzle unit (300) differently depending on the arrangement position of the nozzle unit (300). Therefore, the application device (1000) according to the embodiments has the effect of being able to apply high-viscosity liquid to the target object (10) in one shot.
[0082] Fig. 5 is a drawing showing a nozzle part (300) of a coating device (1000) according to embodiments. More specifically, Fig. 5 shows an exploded view of the nozzle part (300).
[0083] Referring to FIG. 5, the nozzle portion (300) of the application device (1000) according to the embodiments may include an upper member (310), an intermediate member (320), and a lower member (330).
[0084] The upper member (310) can be connected to the flow pipe (200). More specifically, as described in FIG. 4, the upper member (310) can be connected to the second flow pipe (220), and in particular, to the second vertical flow pipe (220-2).
[0085] The upper member (310) may include a passageway (311) to which a flow pipe (200) may be connected. That is, a high viscosity liquid injected through the injection port (101) may move inside the flow pipe (200) and move into the inside of the nozzle unit (300) through the passageway (311). The passageway (311) may be formed in the central portion of the upper member (310).
[0086] The lower member (330) may be formed with a plurality of discharge ports (331). That is, the high viscosity liquid passing through the upper member (310) may be applied to the object (10) through the plurality of discharge ports (331). The discharge ports (331) may be formed in the shape of holes, as illustrated in FIG. 5, or may be formed in the shape of straight lines, etc. A detailed description thereof will be provided in FIG. 7.
[0087] At this time, if the high viscosity liquid moving from the passage (311) of the upper member (310) is applied directly through the discharge port (331) of the lower member (330), the amount of the high viscosity liquid applied through the discharge port (331) located relatively centrally among the plurality of discharge ports (331) may be greater than the amount of the high viscosity liquid applied through the discharge ports (331) located at the outer periphery due to the characteristics of the high viscosity liquid and gravity. That is, if the high viscosity liquid is applied through the upper member (310) and the lower member (330), a phenomenon may occur in which the high viscosity liquid is not applied uniformly to the application area but is applied in a concentrated manner toward the center.
[0088] The nozzle section (300) of the application device (1000) according to the embodiments may further include an intermediate member (320) so that the high viscosity liquid is uniformly applied to the application area.
[0089] Referring to FIG. 5, the intermediate member (320) is positioned between the upper member (310) and the lower member (330), and may have a thickness thinner than the thickness of the upper member (310) or the thickness of the lower member (330). For example, the thickness of the intermediate member (320) may correspond to half the thickness of the upper member (310) or the thickness of the lower member (330).
[0090] In addition, the intermediate member (320) may be formed with a plurality of distribution holes (321). At this time, the position at which the distribution holes (321) are formed may correspond to the position at which the discharge port (331) of the lower member (330) is formed. That is, the distribution hole (321) may be formed in the intermediate member (320) at the same position as the position at which the discharge port (331) is formed in the lower member (330). The distribution hole (321) may be formed in the shape of a hole.
[0091] Accordingly, the high viscosity liquid moving from the passage (311) of the upper member (310) may first move to the distribution hole (321) of the intermediate member (320) rather than moving directly to the discharge port (331) of the lower member (330). Then, the high viscosity liquid moved to the distribution hole (321) may be applied to the application area through the discharge port (331) of the lower member (330).
[0092] The application device (1000) according to the embodiments can uniformly apply a high-viscosity liquid to the application area by means of a distribution hole (321) formed in an intermediate member (320). A detailed description thereof will be provided in FIG. 6.
[0093] In particular, among the plurality of nozzle parts (300), the nozzle part (300) having a cross-sectional area larger than a specific area may include an intermediate member (320). For example, referring to FIG. 4 together, among the first to seventh nozzle parts (301-307), the third nozzle part (303), the fifth nozzle part (305), and the sixth nozzle part (306) having a cross-sectional area larger than a specific area may include an intermediate member (320). Conversely, among the first to seventh nozzle parts (301-307), the first nozzle part (301), the second nozzle part (302), the fourth nozzle part (304), and the seventh nozzle part (307) having a cross-sectional area smaller than a specific area may not include an intermediate member (320).
[0094] That is, among the plurality of nozzle parts (300), the nozzle part (300) having a relatively small cross-sectional area can relatively uniformly apply a high-viscosity liquid even without the intermediate member (320), whereas among the plurality of nozzle parts (300), the nozzle part (300) having a relatively large cross-sectional area may not be able to relatively uniformly apply a high-viscosity liquid if the intermediate member (320) is not present. Therefore, among the plurality of nozzle parts (300), the nozzle part (300) having a relatively large cross-sectional area may include the intermediate member (320), and may uniformly apply the high-viscosity liquid to the application area through the intermediate member (320), more specifically, through the plurality of distribution holes (321) formed in the intermediate member (320).
[0095] Hereinafter, a plurality of distribution holes (321) formed in the intermediate member (320) and a plurality of discharge ports (331) formed in the lower member (320) will be described in detail.
[0096] Fig. 6 is a drawing showing an intermediate member (320) of a nozzle member (300) of a coating device (1000) according to embodiments. Fig. 7 is a drawing showing a lower member (330) of a nozzle member (300) of a coating device (1000) according to embodiments. More specifically, Fig. 6 shows embodiments of a plurality of distribution holes (321) formed in an intermediate member (320), and Fig. 7 shows embodiments of a plurality of discharge ports (331) formed in a lower member (330).
[0097] As described in FIG. 5, the intermediate member (320) of the nozzle portion (300) of the application device (1000) according to the embodiments may include a plurality of distribution holes (321).
[0098] First, referring to (a) of FIG. 6, the plurality of distribution holes (321) formed in the intermediate member (320) may be formed so that their diameters increase as they get farther away from the center of the intermediate member (320). That is, the diameter of the distribution hole (321c) located at the center among the plurality of distribution holes (321) may be formed to be smaller than the diameter of the distribution hole (321e) located at the edge or corner among the plurality of distribution holes (321).
[0099] Referring to FIG. 5, the high viscosity liquid moving from the passage (311) of the upper member (310) can move to the distribution hole (321) of the intermediate member (320). In addition, the moving high viscosity liquid can be concentrated in the central portion of the intermediate member (320) due to the position of the passage (311) formed in the central portion of the upper member (310).
[0100] At this time, for example, if multiple distribution holes (321) are formed to have the same diameter, there is a problem that a relatively large amount of high-viscosity liquid is applied to the central portion of the application area due to the high-viscosity liquid being concentrated in the central portion, and a small amount of high-viscosity liquid is applied to the edge portion of the application area, resulting in the high-viscosity liquid being applied unevenly to the application area.
[0101] On the contrary, as illustrated in (a) of FIG. 6, for example, if the diameter of the distribution hole (321c) located at the center among the plurality of distribution holes (321) is formed relatively small, and the diameter of the distribution hole (321e) located at the edge or corner among the plurality of distribution holes (321) is formed relatively large, even if the high-viscosity liquid is concentrated in the center, the high-viscosity liquid concentrated in the center can move toward the distribution hole (321e) located at the edge or corner without passing through the distribution hole (321c) located at the center, due to the distribution hole (321c) having a small diameter located at the center. In other words, the high-viscosity liquid concentrated in the center passes through both the distribution hole (321c) located at the center and the distribution hole (321e) located at the edge or corner without passing through the distribution hole (321c) located at the center, so that the high-viscosity liquid can be uniformly applied to the application area as a result.
[0102] Accordingly, the application device (1000) according to the embodiments has the effect of being able to uniformly apply a high viscosity liquid to an application area by means of a plurality of distribution holes (321) formed in an intermediate member (320), more specifically, a plurality of distribution holes (321) formed with different diameters depending on the formation position.
[0103] In addition, referring to (b) of FIG. 6, the distribution of the plurality of distribution holes (321) formed in the intermediate member (320) may increase as they get farther away from the center of the intermediate member (320). That is, the number of distribution holes (321e) formed at the edge or corner of the plurality of distribution holes (321) may be greater than the number of distribution holes (321c) formed at the center of the plurality of distribution holes (321).
[0104] Referring to FIG. 5, the high viscosity liquid moving from the passage (311) of the upper member (310) can move to the distribution hole (321) of the intermediate member (320). In addition, the moving high viscosity liquid can be concentrated in the central portion of the intermediate member (320) due to the position of the passage (311) formed in the central portion of the upper member (310).
[0105] At this time, for example, when a plurality of distribution holes (321) are formed in a uniform number in the central member (320), there is a problem that a relatively large amount of high-viscosity liquid is applied to the central portion of the application area due to the high-viscosity liquid being concentrated in the central portion, and a small amount of high-viscosity liquid is applied to the edge portion of the application area, resulting in the high-viscosity liquid being applied unevenly to the application area.
[0106] On the contrary, as illustrated in (b) of FIG. 6, for example, if the number of distribution holes (321c) formed in the center among the plurality of distribution holes (321) is relatively small, and the number of distribution holes (321e) formed in the edges or corners among the plurality of distribution holes (321) is relatively large, even if the high-viscosity liquid is concentrated in the center, the high-viscosity liquid concentrated in the center can move toward the distribution holes (321e) located at the edges or corners without passing through the distribution holes (321c) located in the center due to the small number of distribution holes (321c) formed in the center. In other words, the high-viscosity liquid concentrated in the center can pass through both the distribution holes (321c) formed in the center and the distribution holes (321e) formed at the edges or corners without passing through the distribution holes (321c) formed in the center, resulting in the high-viscosity liquid being uniformly applied to the application area.
[0107] Accordingly, the application device (1000) according to the embodiments has the effect of being able to uniformly apply a high viscosity liquid to an application area by means of a plurality of distribution holes (321) formed in an intermediate member (320), more specifically, a plurality of distribution holes (321) formed in which the number of formations varies depending on the formation position.
[0108] As described in FIG. 5, the lower member (330) of the nozzle portion (300) of the application device (1000) according to the embodiments may include a plurality of discharge ports (331).
[0109] The plurality of discharge ports (331) formed in the lower member (330) may be formed in the shape of a hole, as shown in FIG. 5, or may be formed in the shape of a straight line, a bent straight line, a polygonal hole, etc., as shown in FIG. 7.
[0110] Additionally, multiple outlets (331) can be arranged to form a specific pattern.
[0111] First, referring to (a) of FIG. 7, the plurality of discharge ports (331) may be formed in the shape of holes, bent straight lines, etc. In addition, the plurality of discharge ports (331) may be arranged to form a rectangular pattern. The shape or specific pattern of the plurality of discharge ports (331) may be formed in a shape or specific pattern that allows a high-viscosity liquid to be uniformly applied to the application area depending on the formation position or formation size of the plurality of distribution holes (321) formed in the intermediate member (320).
[0112] Alternatively, referring to (b) of FIG. 7, the plurality of discharge ports (331) may be formed of circular holes, holes having a straight shape, holes having a triangular cross-section, etc. In addition, the plurality of discharge ports (331) may be arranged to form a radial pattern. The shape or specific pattern of the plurality of discharge ports (331) may be formed in a shape or specific pattern that allows a high-viscosity liquid to be uniformly applied to the application area depending on the formation position or formation size of the plurality of distribution holes (321) formed in the intermediate member (320).
[0113] Accordingly, the application device (1000) according to the embodiments has the effect of being able to uniformly apply a high viscosity liquid to the application area by various shapes of the plurality of discharge ports (331) formed in the lower member (320).
[0114] Fig. 8 is a drawing showing an object (10) to which a high-viscosity liquid has been applied by a coating device (1000) according to embodiments. More specifically, Fig. 8 is a drawing showing an object (10) to which a high-viscosity liquid has been applied by the flow pipe (200) and the first to seventh nozzle sections (301-307) shown in Fig. 4.
[0115] Referring to FIG. 8, the application device (1000) according to the embodiments can apply a high viscosity liquid such as TIM paste, thermal grease, etc. to an application area among the target object (10). For example, the application area may correspond to an electronic component (11-1, 2, 3, 4, 5, 6, 7) having a heat generation amount higher than a standard among several electronic components (11) mounted on a printed circuit board.
[0116] For example, referring to FIG. 4, the application device (1000) according to the embodiments can apply a high viscosity liquid to a first application area among a plurality of application areas through a first nozzle unit (301) among a plurality of nozzle units (300). The first application area can correspond to a first electronic component (11-1) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.
[0117] Alternatively, for example, the application device (1000) according to the embodiments may apply a high-viscosity liquid to a second application area among a plurality of application areas through a second nozzle unit (302) among a plurality of nozzle units (300). The second application area may correspond to a second electronic component (11-2) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.
[0118] Alternatively, for example, the application device (1000) according to the embodiments may apply a high-viscosity liquid to a third application area among a plurality of application areas through a third nozzle unit (303) among a plurality of nozzle units (300). The third application area may correspond to a third electronic component (11-3) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.
[0119] Alternatively, for example, the application device (1000) according to the embodiments may apply a high-viscosity liquid to a fourth application area among a plurality of application areas through a fourth nozzle unit (304) among a plurality of nozzle units (300). The fourth application area may correspond to a fourth electronic component (11-4) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.
[0120] Alternatively, for example, the application device (1000) according to the embodiments may apply a high-viscosity liquid to a fifth application area among a plurality of application areas through a fifth nozzle unit (305) among a plurality of nozzle units (300). The fifth application area may correspond to a fifth electronic component (11-5) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.
[0121] Alternatively, for example, the application device (1000) according to the embodiments may apply a high-viscosity liquid to a sixth application area among a plurality of application areas through a sixth nozzle unit (306) among a plurality of nozzle units (300). The sixth application area may correspond to a sixth electronic component (11-6) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.
[0122] Alternatively, for example, the application device (1000) according to the embodiments may apply a high-viscosity liquid to a seventh application area among a plurality of application areas through a seventh nozzle unit (307) among a plurality of nozzle units (300). The seventh application area may correspond to a seventh electronic component (11-7) among a plurality of electronic components (11) having a heat generation amount greater than a reference value.

In other words, the application device (1000) according to the embodiments has the effect of being able to apply high-viscosity liquids to multiple application areas at once or simultaneously through one injection port (101) or one device via the first to seventh nozzle sections (301-307).
