Description

Automatic water-repellent coating and drying device for insulation

[0001] The present invention relates to an automatic water-repellent coating and drying device for thermal insulation materials, and more specifically, to an automatic water-repellent coating and drying device for thermal insulation materials capable of automatically water-repellent coating and drying the surface of thermal insulation materials used in automobiles.

[0002] Aerogel insulation is used between cells in automotive batteries to prevent fire. To enhance the insulation effect, a water-repellent coating is applied to the surface of this insulation.

[0003] Conventionally, the water-repellent coating process for insulation materials was performed manually by workers. Specifically, a worker directly sprayed a fluorine solution onto the surface of the insulation material placed on a jig to form a water-repellent coating layer, and then underwent a waterproofing process to verify the water-repellent performance after drying.

[0004] However, since this conventional water-repellent coating process for insulation materials is performed manually by workers, it had limitations such as reduced production efficiency and inconsistent quality. In addition, it had the disadvantage of high production costs due to the need for worker labor.

[0006] Published Patent No. 10-1999-0044997 "Water-repellent coating method and coating apparatus used therein"

[0007] The objective of the present invention is to solve the aforementioned problem by providing a water-repellent coating and drying device for insulation materials that enables the entire process of loading, water-repellent coating, drying, and unloading of insulation materials to proceed automatically without operator intervention.

[0009] The above-mentioned objectives and various advantages of the present invention will become more apparent to those skilled in the art from the preferred embodiments of the present invention.

[0010] The objective of the present invention can be achieved by an automatic water-repellent coating and drying device for thermal insulation. The automatic water-repellent coating and drying device for thermal insulation according to the present invention comprises: a circulation track (110) forming a circulation path; a movable carriage (120) moving along the circulation track (110) with a thermal insulation material (A) mounted on its upper surface; a loading unit (130) provided on one side of the circulation track (110) for loading the thermal insulation material (A) onto the movable carriage (120); a water-repellent coating unit (150) provided on the path of the circulation track (110) for spraying a water-repellent coating liquid toward the thermal insulation material (A) mounted on the movable carriage (120) to form a water-repellent coating layer on the surface of the thermal insulation material (A); and a drying unit (160) for drying the water-repellent coating layer by applying heat from the circulation track (110) to the movable carriage (120) via the water-repellent coating unit (150).

[0023]

[0024] To fully understand the present invention, preferred embodiments of the invention are described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0025] FIG. 1 is a schematic plan view illustrating the overall configuration of a water-repellent coating and drying device (100) for thermal insulation material according to the present invention.

[0026] As described above, the water-repellent coating and drying device (100) for insulating material according to the present invention comprises a circulation track (110) forming a circulation path, a movable carriage (120) moving along the circulation track (110) with insulating material (A) mounted on its upper surface, a loading unit (130) provided on one side of the circulation track (110) for loading insulating material (A) onto the movable carriage (120), a water-repellent coating unit (150) provided on the path of the circulation track (110) for forming a water-repellent coating layer (A-2) by spraying a coating liquid (B) onto the movable carriage (120) moved from the loading unit (130), a drying unit (160) for drying the water-repellent coating layer (A-2) by applying heat to the movable carriage (120) that has passed through the water-repellent coating unit (150), and a device for unloading insulating material (A) from the movable carriage (120) that has passed through the drying unit (160). It includes an unloading unit (140).

[0027] In the insulation material water-repellent coating and drying device (100) according to the present invention, when the loading unit (130) loads the insulation material (A) onto the movable cart (120), the movable cart (120) moves along the circulation track (110) and sequentially moves through the water-repellent coating unit (150), the drying unit (160), and the unloading unit (140), thereby automatically performing the water-repellent coating process and the drying process for the insulation material (A). The insulation material (A') with the water-repellent coating completed is unloaded by the unloading unit (140) and discharged to the loading platform (10).

[0028] The water-repellent coating and drying device (100) for insulating material according to the present invention automatically performs the entire water-repellent coating and drying process on insulating material (A) without the intervention of a worker, and can omit the waterproofing process required when performing the work manually. Accordingly, the efficiency and quality of the water-repellent coating work on insulating material can be improved and manufacturing costs can be reduced.

[0029] The insulating material (A) that undergoes water-repellent coating through the insulating material water-repellent coating and drying device (100) of the present invention may be an insulating material (A) used in a car battery. As shown in FIG. 2, the insulating material (A) is provided in the form of a semi-cylindrical tube, and a water-repellent coating layer (A-2) is formed on the outer surface.

[0030] However, the insulating material (A) applied to the present invention can be applied not only to the semi-cylindrical shape shown in the drawing but also to various shapes of insulating material (A), such as flat plates, curved plates, and multi-combined shapes.

[0031] Here, the insulating material (A) indicated by the symbol "A" in FIG. 1 refers to a state in which a water-repellent coating layer is not formed, and the insulating material (A') indicated by the symbol "A'" refers to a state in which a water-repellent coating layer (A-2) is formed.

[0032] The circulation track (110) guides the moving carriage (120) to move sequentially through the water-repellent coating section (150), the drying section (160), and the unloading section (140). The circulation track (110) can be modified into various shapes, not only in the illustrated ellipse but also to form a circulation path capable of moving sequentially through the water-repellent coating section (150), the drying section (160), and the unloading section (140).

[0033] The circulation track (110) of the present invention moves a movable carriage (120) by means of a magnetic linear motor. To this end, as shown in FIG. 2, the circulation track (110) includes a track body (111) that is horizontally matched with respect to the ground, a plurality of electromagnets (113) arranged at regular intervals on the track body (111), and a pair of rails (115) arranged on the upper surface along the longitudinal direction of the track body (111) to guide the movable carriage (120).

[0034] The movable trolley (120) comprises a plate-shaped trolley body (121) having a certain length, a permanent magnet (123) provided at the lower part of the trolley body (121), a support (125) placed on the upper surface of the trolley body (121) on which an insulating material (A) is mounted, and a plurality of wheels (124) placed on both sides of the permanent magnet (123) and rotated by engaging with a rail (115).

[0035] The electromagnets (113) arranged along the longitudinal direction of the circulation track (110) generate a magnetic field whenever current flows. This magnetic field changes sequentially between the N pole and the S pole over time. The permanent magnets (123) provided at the bottom of the movable carriage (120) move along the track body (111) through the interaction of attractive and repulsive forces according to the change in polarity of the electromagnets (113) of the circulation track (110).

[0036] At this time, the multiple wheels (124) move while engaged with the rail (115), allowing the moving carriage (120) to move stably without leaving the circulation track (110).

[0037] The circular track (110) employs a magnetic linear motor method, allowing the moving carriage (120) to move accurately and stably even on a curved path.

[0038]

[0039] A support (125) provided on the upper surface of the movable carriage (120) supports the insulation material (A) so that it remains stationary and its position is fixed while the movable carriage (120) moves along the circulation track (110) and sequentially passes through the water-repellent coating section (150), the drying section (160), and the unloading section (140). The support (125) is provided in the form of a column with a semicircular cross-section suitable for the insulation material (A), which is in the shape of a semi-cylindrical tube.

[0040] The outer diameter of the mounting bracket (125) is provided to correspond to the inner diameter of the inner groove (A-1) of the insulation material (A), so that the mounting bracket (125) is fitted into the insulation material (A) and supports the insulation material (A).

[0041] It is preferable that the length of the movable carriage (120) corresponds to the length of the insulation material (A) or is shorter than the length of the insulation material (A).

[0042] It includes a vertical axis (131) arranged in such a way, a Y-axis transfer unit (135) arranged between a loading platform (10) and a circulation rail (115) on the upper part of the vertical axis (131), an X-axis transfer unit (133) provided to be movable along the Y-axis transfer unit (135) and provided perpendicularly to the Y-axis transfer unit (135), a Z-axis transfer unit (137) provided to be movable in the X-axis direction along the X-axis transfer unit (133) and arranged perpendicularly to the X-axis transfer unit (133), a transfer block (138) provided to be movable in the Z-axis direction along the Z-axis transfer unit (137), and an adsorption head (139) provided on the lower part of the transfer block (138) and adsorbing and fixing an insulating material (A) by vacuum pressure.

[0043] The X-axis transfer unit (133), Y-axis transfer unit (135), and Z-axis transfer unit (137) are provided to be movable in the corresponding direction using an LM guide method. That is, the transfer block (138) moves up and down in the Z-axis direction along the Z-axis transfer unit (137), and the Z-axis transfer unit (137) moves in the X-axis direction along the X-axis transfer unit (133). In addition, the X-axis transfer unit (133) moves in the Y-axis direction along the Y-axis transfer unit (135).

[0044] By the mutual operation of the X-axis transfer unit (133), the Y-axis transfer unit (135), and the Z-axis transfer unit (137), the suction head (139) sucks up and picks up the insulation material (A) loaded on the loading platform (10) by vacuum pressure, and places the insulation material (A) on the mounting platform (125) on the upper part of the movable carriage (120).

[0045] A vacuum pressure generating unit (not shown in the drawing) is connected between the suction head (139) and the transfer block (138) to apply or release vacuum pressure to the suction head (139), thereby causing the insulating material (A) to be fixed to or separated from the suction head (139).

[0046] The suction head (139) is provided with a semi-cylindrical shape identical to that of the insulation material (A) so as to easily suction the insulation material (A) which is semi-cylindrical. The inner wall surface of the suction head (139) is provided with an inner diameter corresponding to the outer diameter of the insulation material (A) so as to be in close contact with the outer wall surface of the insulation material (A). Although not shown in the drawing, a plurality of vacuum pressure application processes (not shown) for applying vacuum pressure are formed on the inner wall surface of the suction head (139), and vacuum pressure applied from a vacuum pressure generating part (not shown) is applied to the insulation material (A).

[0047] The loading unit (130) loads the insulation material (A) of the loading platform (10) onto the mounting platform (125) of the movable cart (120). The unloading unit (140) unloads the insulation material (A) from the mounting platform (125) of the movable cart (120) and loads it onto the loading platform (10).

[0048] FIG. 3 is an example diagram illustrating the operation process of the loading unit (130) and the unloading unit (140). Since the loading unit (130) and the unloading unit (140) have the same configuration, only the loading unit (130) will be described in detail.

[0049] The loading unit (130) is positioned on one side of the circulation track (110) to pick up insulation material (A) from the loading platform (10) and place the insulation material (A) on the mounting platform (125) of the movable cart (120). The loading unit (130) is positioned vertically on one side of the circulation track (110).

[0050]

[0051] As shown in FIG. 1, the water-repellent coating section (150) is provided for a certain length on the path of the circulation track (110), and a water-repellent coating liquid (B) is sprayed onto the insulation material (A) transported while mounted on the movable cart (120) to form a water-repellent coating layer (A-2) on the surface of the insulation material (A).

[0052] The water-repellent coating liquid (B) used in the water-repellent coating part (150) is provided in a liquid form, and various types of fluoropolymer resins (e.g., PTFE, FEP, PFA, etc.) can be used.

[0053] FIG. 4 is a cross-sectional example diagram illustrating the cross-sectional configuration of the water-repellent coating part (150). As illustrated in FIG. 4, the water-repellent coating unit (150) comprises a coating chamber (151) provided to surround the circulation track (110), a plurality of spray nozzles (153) arranged at regular intervals on the inner wall surface of the coating chamber (151) to spray a water-repellent coating liquid (B) toward the insulation material (A), a coating liquid tank (155) provided on the outside of the circulation track (110) to store the water-repellent coating liquid (B), a coating liquid supply pipe (157) connecting the coating liquid tank (155) and the coating chamber (151) to supply the coating liquid (B), and a coating liquid recovery pipe (154) connecting the lower part of the coating chamber (151) and the coating liquid tank (155) to recover the remaining water-repellent coating liquid (B) after coating the insulation material (A) to the coating liquid tank (155).

[0054] The coating chamber (151) surrounds the circulation track (110) to prevent the water-repellent coating liquid (B) sprayed from the spray nozzle (153) from being sprayed into other areas or contaminating other areas. Additionally, the coating chamber (151) also performs the function of collecting the water-repellent coating liquid (B) from below so that the water-repellent coating liquid (B) reflected from the surface of the insulation material (A) and falling downward can be recovered.

[0055] In the drawing, the bottom of the coating chamber (151) is provided flat, but in some cases, it may be provided in a slanted shape to facilitate the collection of the water-repellent coating liquid (B).

[0056] It is preferable that the length of the coating chamber (151) corresponds to the length of the movable carriage (120) or is formed to be of a certain length so that the water-repellent coating liquid (B) can be coated on the insulating material (A) in one go.

[0057] A plurality of spray nozzles (153) are provided at regular intervals on the inner wall surface of the coating chamber (151) to spray a water-repellent coating liquid (B) onto the surface of the insulation material (A) loaded on the movable cart (120). The spray nozzles (153) spray the water-repellent coating liquid (B) at a pressure set by a control unit (not shown). Each spray nozzle (153) is set with a different spray angle so that the water-repellent coating liquid (B) can be uniformly applied to the surface of the entire insulation material (A).

[0058] The coating chamber (151) is connected to the coating liquid supply pipe (157), and a coating liquid distribution channel (151a) is formed inside the coating chamber (151) to distribute the coating liquid to a plurality of spray nozzles (153). The water-repellent coating liquid (B) transferred to the coating liquid supply pipe (157) is distributed to the plurality of spray nozzles (153) through the coating liquid distribution channel (151a) and sprayed onto the surface of the insulation material (A) through the spray nozzles (153).

[0059]

[0060] The coating liquid tank (155) is positioned outside the circulation track (110) and stores a water-repellent coating liquid (B) inside. The coating liquid tank (155) is connected to a coating liquid supply pipe (157). A coating liquid pump (156) is provided between the coating liquid supply pipe (157) and the coating liquid tank (155) to supply the coating liquid (B) to the coating chamber (151).

[0061] Meanwhile, the coating liquid recovery pipe (154) connects the lower outer wall surface of the coating chamber (151) and the outer wall surface of the coating liquid tank (155) to recover the remaining water-repellent coating liquid (B) remaining after use in the coating to the coating liquid tank (155).

[0062] At this time, a filter (155a) is provided at the end of the coating liquid recovery pipe (154) to filter out foreign substances remaining in the collected water-repellent coating liquid (B).

[0063] Meanwhile, an auxiliary heater (158) as well as a spray nozzle (153) may be provided on the inner wall surface of the coating chamber (151). The auxiliary heater (158) is operated by the control of a control unit (not shown) in the case of a water-repellent coating liquid (B) that requires immediate drying.

[0064] The drying section (160) passes through the water-repellent coating section (150) and applies heat (H) to the insulating material (A) on which the water-repellent coating layer (A-2) is formed on the surface to dry the water-repellent coating layer (A-2). The drying section (160) is located after the water-repellent coating section (150) along the transport direction of the movable carriage (120) of the circulation track (110). Accordingly, the movable carriage (120) can move directly to the drying section (160) after passing through the water-repellent coating section (150).

[0065] FIG. 5 is a cross-sectional example illustrating the cross-sectional configuration of a drying section (160). As illustrated, the drying section (160) includes a drying chamber (161) provided to surround a circulation track (110) and a plurality of heaters (163) provided on the inner wall surface of the drying chamber (161). The drying chamber (161) is provided to surround the circulation track (110) so as to minimize heat loss.

[0066] Multiple heaters (163) generate heat toward the insulation material (A) of the movable carriage (120) to rapidly dry the water-repellent coating layer (A-2). The heaters (163) are driven to a temperature corresponding to the type of water-repellent coating liquid (B) sprayed on the insulation material (A) under the control of a control unit (not shown).

[0067] Meanwhile, in addition to the heater (163), the drying section (160) may be equipped with a UV curing lamp (not shown). The UV curing lamp (not shown) is activated when a water-repellent coating liquid (B) of a type requiring UV curing is applied to the insulation material (A).

[0068] A control unit (not shown) controls each component so that after the insulation material (A) is loaded onto the movable carriage (120), it passes through the water-repellent coating unit (150) and the drying unit (160) to form a water-repellent coating layer (A-2) and is then unloaded. The control unit (not shown) enables a water-repellent coating liquid selected according to the shape and material of the insulation material to be applied to the insulation material (A) with a uniform thickness.

[0069] To this end, a control unit (not shown) controls the transfer speed of the movable carriage (120), the stopping time of the movable carriage (120), the number of coatings, the spray pressure of the nozzle, the drying temperature, etc.

[0070]

[0071] The operation process of the thermal insulation material water-repellent coating and drying device (100) according to the present invention having such a configuration will be explained with reference to FIGS. 1 to 5.

[0072] A water-repellent coating and drying device (100) for insulating material according to a preferred embodiment of the present invention sprays a water-repellent coating liquid (B) a total of four times to form a water-repellent coating layer (A-2) on insulating material (A). That is, 25% of the final water-repellent coating layer (A-2) thickness is formed in the first step, and 25% is formed in the second, third, and fourth steps, respectively.

[0073] This is just an example, and depending on the case, the water-repellent coating layer (A-2) can be completed in one step or over five or more steps.

[0074] As illustrated in FIG. 1, an elliptical circulation track (110) is prepared. A movable carriage (120) is movably provided on the circulation track (110). Electromagnets (113) are provided at regular intervals on the circulation track (110), and permanent magnets (123) are provided on the lower part of the movable carriage (120). A control unit (not shown) changes the direction of current of the electromagnets (113) to the direction in which the movable carriage (120) moves, causing the movable carriage (120) to move along the circulation track (110) by magnetic force.

[0075] When the movable carriage (120) enters the loading section (130), the movable carriage (120) stops on the circulation track (110) under the control of the control section (not shown). At this time, as shown in FIG. 3, the suction head (139) of the loading section (130) suctions the insulation material (A) loaded on the loading platform (10) and then places the insulation material (A) on the mounting platform (125) on the upper part of the movable carriage (120).

[0076] The mounting bracket (125) is equipped with a detection sensor (not shown) capable of detecting whether the insulation material (A) is mounted, and the control unit (not shown) starts the moving cart (120) when the mounting of the insulation material (A) is detected. The moving cart (120) moves along the circulation track (110) and enters the water-repellent coating unit (150).

[0077] When the entire movable carriage (120) enters the coating chamber (151) of the water-repellent coating section (150), the control unit (not shown) operates the coating liquid pump (156) so that a plurality of spray nozzles (153) spray the water-repellent coating liquid (B) onto the insulating material (A). At this time, the control unit (not shown) controls the spraying time and the amount of spray so that the plurality of spray nozzles (153) spray the water-repellent coating liquid (B) onto the surface of the insulating material (A) to a thickness of 25% of the total water-repellent coating layer (A-2).

[0078] When the spraying of the water-repellent coating liquid (B) is completed for the time set by the control unit (not shown), the operation of the coating liquid pump (156) stops. Then, the moving cart (120) operates again and moves to the drying unit (160). Meanwhile, the remaining water-repellent coating liquid (B) that fell to the bottom of the coating chamber (151) is recovered into the coating liquid tank (155) through the coating liquid recovery pipe (154).

[0079]

[0080] As illustrated in FIG. 5, when the movable carriage (120) enters the drying chamber (161) of the drying unit (160), the heater (163) generates heat (H) to dry the water-repellent coating layer (A-2) formed in the first step. The control unit (not shown) adjusts the temperature and heating time of the heater (163) according to the type of water-repellent coating liquid (B).

[0081] The moving carriage (120), which is stopped inside the drying chamber (161) and has the water-repellent coating layer (A-2) dried by heat (H) applied from the heater (163), moves and moves again to the water-repellent coating section (150) along the circulation track (110).

[0082] In this way, the moving cart (120), having passed through the water-repellent coating section (150) and the drying section (160) a total of four times, moves along the circulation track (110) to the unloading section (140). As shown in FIG. 3, at the unloading section (140), the suction head (139) suctions the insulating material (A) with the water-repellent coating layer (A-2) formed on the mounting bracket (125) of the moving cart (120) and loads it onto the loading platform (10).

[0083] The mobile cart (120) from which the insulation material (A) has been discharged is moved to the loading unit (130), and a new insulation material (A) is received by the loading unit (130), and a water-repellent coating and drying process for the insulation material (A) is carried out in the same process as before.

[0084] As described above, the water-repellent coating and drying device for thermal insulation according to the present invention automatically performs the water-repellent coating and drying process on the thermal insulation by placing the thermal insulation on a transport cart, moving it along a circulation track, and sequentially passing through the water-repellent coating section and the drying section. The thermal insulation, upon completion of the formation of the water-repellent coating layer, is automatically discharged by the unloading section.

[0085] Since the entire process of the water-repellent coating and drying device for thermal insulation materials according to the present invention is performed automatically, no intervention by a worker is required, thereby minimizing manpower input and reducing labor costs.

[0086] In addition, compared to conventional manual methods, it has the advantages of maintaining uniform quality, eliminating the waterproofing process, and improving production efficiency.
