Description

Swirl dispenser device

[0001] The present invention relates to a swirl dispenser device for applying a sealer in a swirl form to a body panel or the like.

[0002] The content described below only provides background information for the present embodiment and does not describe prior art.

[0003] An automobile body is composed of various metal panels and parts. Metal panels or parts can be joined by welding. However, to prevent material deformation due to welding, a method of joining panels using a liquid substance that hardens after application is used. This liquid substance is referred to as a sealer. Sealers can be used to join structural body panels. Sealers can also be used to bond automotive glass to body panels. Sealers applied to panels can be cured by heat or by reacting with moisture in the air, exhibiting properties such as adhesion, sealing, vibration damping, rust prevention, waterproofing, and reinforcing rigidity.

[0004] The sealer can be applied to the surface of the panel by an application gun. The sealer can be continuously ejected from the application gun and applied to the surface of the panel in a predetermined pattern. Examples of sealer application patterns include a stream pattern, a spot pattern, a bead pattern, and a swirl pattern. The sealer applied in a swirl pattern can fill a wide space between two joint members. Accordingly, in an application example where the sealer needs to be applied in a wide space, an application gun configured to apply the sealer in a swirl pattern can be used. Such a sealer application gun for a swirl pattern must be equipped with a device or mechanism for creating a swirl pattern of the sealer.

[0005] Conventional sealer application guns for swirl patterns are designed only from the perspective of equipping the application gun with the above device or mechanism.

[0006] Accordingly, conventional sealer application guns for swirl patterns are designed with complex structures and are heavy. Furthermore, conventional sealer application guns for swirl patterns are not designed to exhibit good application quality, as they only have devices or mechanisms for creating swirl patterns. Furthermore, conventional sealer application guns for swirl patterns are only suitable for applying sealer to flat panels, and are not easily applied to panels with complex shapes.

[0007] To solve these problems, a swirl sealer application gun and a swirl sealer application device including the same, patented under patent registration number 10-2346348, have been disclosed as shown in Fig. 1. However, the prior art also has limitations in applying the sealer continuously and uniformly at regular intervals, as shown in Fig. 2.

[0008] The present invention was created to solve the above-mentioned problems and needs, and its purpose is to provide a swirl dispenser device capable of applying a sealer continuously and uniformly at regular intervals.

[0009] In order to achieve the above object, a swirl dispenser device according to a first embodiment of the present invention is a device for applying a sealer in a swirl form, comprising: a housing into which the sealer is supplied and which has a stator therein; a rotor shaft which has a rotor interacting with the stator and is coupled to the inside of the housing to rotate around a rotational axis and which is formed hollow; a hollow sealer shaft having a first spherical rotary port fixed to one end through which the sealer is introduced and inserted into the inside of the housing, a nozzle for spraying the sealer is formed at the other end, and which is formed to penetrate the rotor shaft along the rotational axis; a first holder which is seated on one side of the inside of the housing coaxially with the rotational axis and receives the first rotary port; and a second holder which is fixed to the rotor shaft coaxially with the rotational axis and supports the other side of the sealer shaft and eccentrically rotates the sealer shaft along the rotational axis, and the first holder is configured to rotate the first rotary port. The first rotating member is supported by receiving it in a concave shape, and the second holder is coupled to enable tilting rotation, and the outer surface of the other side of the sealer shaft is supported by a bearing that is eccentric in a direction orthogonal to the rotation axis.

[0010] According to the present invention, a first spherical rotating ball is accommodated inside the housing and is capable of three-dimensional point (ball) rotation without bending, thereby resolving the conventional problem and providing the advantage of being able to continuously and uniformly apply a sealer at regular intervals.

[0011] In addition, the sealer filled in the space within the sealer shaft acts as a buffer, so it controls the sealer opening and closing part that is spaced apart without being easily affected by temperature changes, so there is an advantage in that it can effectively block the open nozzle.

[0012] In addition, there is an advantage in that the second rotary member (232) having an outer surface in the shape of a sphere or ellipsoid can be freely rotated in three dimensions like a joystick while being accommodated in the second holder, thereby complementing the sealer shaft of the first embodiment.

[0013] The effects according to the present invention are not limited to the contents exemplified above, and more diverse effects are included within the specification of the present invention.

[0024] Meanwhile, in FIGS. 3 to 5, tubes or pipes for supplying working fluid, wires for supplying power or transmitting electric signals, etc. are omitted.

[0025] Referring to the drawings mentioned above, a swirl dispenser device (100) according to a first embodiment of the present invention is a device for applying a sealer (SL) in a swirl form, comprising a housing (110) into which the sealer (SL) is supplied and which has a stator (111) therein, a rotor shaft (120) which is formed hollow and which is coupled to the inside of the housing (110) to rotate around a rotational axis (RY) and which has a rotor (121) which interacts with the stator (111), a first spherical rotating hole (131) fixed on one side through which the sealer (SL) is introduced and inserted into the inside (110) of the housing, a nozzle (133) which sprays the sealer (SL) is formed on the other side, and a hollow sealer shaft (130) formed to penetrate the rotor shaft (120) along the rotational axis (RY), and coaxially with the rotational axis (RY). It includes a first holder (140) that is mounted on one side of the inside of the housing (110) to accommodate the first rotary member (131), and a second holder (150) that is fixed to the rotor shaft (120) coaxially with the rotation axis (RY) to support the other side of the sealer shaft (130) and tilt the sealer shaft (130) along the rotation axis (RY) to eccentrically move the nozzle (133) from the rotation axis (RY).

[0026] In addition, the first holder (140) may be configured to receive and support the first rotary member (131) in a recessed shape, and the first rotary member (131) may be coupled to be capable of tilting rotation, and the second holder (150) may be coupled to a bearing (151) that supports the outer surface of the other side of the sealer shaft (130) and is eccentric in a direction orthogonal to the rotation axis (RY).

[0027] In addition, the first holder (140) has a pair of inductive members (141) that wrap around the outer surface of the first rotary member (131) at a predetermined height as if spreading out two arms, and a ring member (142) with a cross-section shaped like the letter "ㅓ" between the pair of inductive members (141) can support the outer side of the first rotary member (131).

[0028] In addition, the second holder (150) can incline the sealer shaft (130) so that the eccentricity (EY) of the sealer shaft (130) increases from the first rotary member (131) toward the second holder (150).

[0029] Additionally, the bearing (151) may be configured to allow circular motion of the sealer shaft (130) centered on the rotation axis (RY).

[0030] Alternatively, the bearing (151) may be configured to allow a conical motion of the sealer shaft (130) centered on the first rotary member (131).

[0031] In addition, a sealer opening / closing unit (160) that opens / closes a sealer passage (161) formed to be connected to the sealer shaft (130) by a sealer valve (162) may be further included.

[0032] In addition, the sealer opening / closing unit (160) can open the sealer passage (161) by the sealer valve (162) when applying the sealer to maintain the pressure within the sealer shaft (130) higher than the atmospheric pressure, and when application of the sealer is stopped, the sealer within the sealer shaft (130) can be sucked in (like sniffing snot with the nose) to close the sealer passage (161) to make the pressure within the sealer shaft (130) lower than the atmospheric pressure.

[0033] That is, when the sealer is applied, the sealer opening / closing unit (160) opens the sealer passage (161) by the sealer valve (162) so that the pressure inside the sealer shaft (130) is maintained higher than the atmospheric pressure, thereby ejecting the sealer (SL) through the nozzle (133), and when the sealer application is stopped, the sealer (SL) inside the sealer shaft (130) is sucked in (as if wiping mucus with the nose) so that the sealer passage (161) is closed, so that the pressure inside the sealer shaft (130) is lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out from the nozzle (133).

[0034] A swirl dispenser device (200) according to a second embodiment of the present invention is a device for applying a sealer (SL) in a swirl form, comprising: a housing (210) into which the sealer (SL) is supplied and which has a stator (211) therein; a rotor shaft (220) which has a rotor (221) interacting with the stator (211) and which is formed hollow and coupled to rotate around a rotational axis (RY) inside the housing (210); a first rotary port (231) in the shape of a sphere fixed on one side through which the sealer (SL) is introduced and inserted into the interior (210) of the housing; a nozzle (233) which sprays the sealer (SL) is formed on the other side and which is formed to penetrate the rotor shaft (220) along the rotational axis (RY); and a hollow sealer shaft (230) which is formed coaxially with the rotational axis (RY) inside the housing (210). It includes a first holder (240) that is mounted on one side and accommodates the first rotary member (231), and a second holder (250) that is fixed to the rotor shaft (220) coaxially with the rotation axis (RY) to support the other side of the sealer shaft (230) and tilts the sealer shaft (230) along the rotation axis (RY) to eccentrically position the nozzle (233) from the rotation axis (RY).

[0035] In addition, the first holder (240) may be configured to receive and support the first rotary member (231) in a recessed shape, and the first rotary member (231) may be coupled to be capable of tilting rotation, and the second holder (250) may be coupled to a bearing (251) that supports the outer surface of the other side of the sealer shaft (230) and is eccentric in a direction orthogonal to the rotation axis (RY).

[0036] In addition, the first holder (240) has a pair of inductive members (241) that wrap around the outer surface of the first rotary member (231) at a predetermined height as if spreading out two arms, and a ring member (242) with a cross-section shaped like the letter "ㅓ" between the pair of inductive members (241) supports the outer side of the first rotary member (231) to minimize contact with the first rotary member (231).

[0037] In addition, the second holder (250) can incline the sealer shaft (230) so that the eccentricity (EY) of the sealer shaft (230) increases from the first rotary member (231) toward the second holder (250).

[0038] Additionally, the bearing (251) may be configured to allow circular motion of the sealer shaft (230) centered on the rotation axis (RY).

[0039] Alternatively, the bearing (251) may be configured to allow a conical motion of the sealer shaft (230) centered on the first rotary member (231).

[0040] In addition, a sealer opening / closing unit (260) that opens / closes a sealer passage (261) formed to be connected to the sealer shaft (230) by a sealer valve (262) may be further included.

[0041] In addition, the sealer opening / closing unit (260) can open the sealer passage (261) by the sealer valve (262) when applying the sealer to maintain the pressure within the sealer shaft (230) higher than the atmospheric pressure, and when applying the sealer is stopped, the sealer (SL) within the sealer shaft (230) can be sniffed to close the sealer passage (261) to lower the pressure within the sealer shaft (230) to lower than the atmospheric pressure.

[0042] That is, when applying the sealer, the sealer opening / closing unit (260) opens the sealer passage (261) through the sealer valve (262) to spray the sealer (SL) through the nozzle (233), and when application of the sealer is stopped, the sealer (SL) inside the sealer shaft (230) is sucked in (like sniffing snot with the nose) to close the sealer passage (261), so that the pressure inside the sealer shaft (230) becomes lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out through the nozzle (233).

[0043] In addition, the sealer shaft (230) has a second rotary member (232) in the shape of a sphere or ball formed on the outer surface of the other side, and the second holder (250) is coupled to the bearing (251) which is eccentric in a direction orthogonal to the rotation axis (RY), and can support the second rotary member (232) by receiving it in a concave shape.

[0044] In addition, the second holder (250) can slide the bearing (251) along the ascending and descending direction of the sealer shaft (230).

[0045] In addition, the bearing (251) is a double bearing, and has a groove (252) formed on the inner surface to surround and accommodate the second rotary member (232) and enable rolling movement in the vertical direction.

[0046] In addition, it further includes an extension part (270) installed in the housing (210) to elevate the first holder (240), and the extension part (270) elevates the first holder (240) that rotatably holds the first rotary member (231) so that the other side of the sealer shaft (230) on which the nozzle (233) is formed can be proportionally elevated to adjust the height.

[0047] In addition, the elastic member (270) can be watertight or airtight inside the housing (210) to elevate the first holder (240).

[0048] Then, the configuration and operation of the swirl dispenser device (100, 200) according to embodiments of the present invention will be described in detail as follows.

[0049] A swirl dispenser device (100) according to a first embodiment of the present invention is a device for applying a sealer (sealer or sealant) in a swirl form, as illustrated in FIG. 3, and includes a housing (110), a rotor shaft (120), a sealer shaft (130), a first holder (140), a second holder (150), etc.

[0050] The housing (110) constitutes the body of the swirl dispenser device (100) proposed by the present invention and houses components for ejecting the sealer (SL) and creating a swirl pattern therein. The sealer (SL) is supplied from a sealer supply source (not shown) along a path formed within the housing (110).

[0051] The housing (110) is a component of a motor that generates rotational force and has a stator (111) therein. The stator (111) is located outside a rotor (121) to be described later and has a ring shape. The stator (111) receives power from a power source through a power connector (not shown) attached to the housing (110). Meanwhile, the housing (110) may be composed of a plurality of blocks for easy maintenance by assembling or disassembling, and may be watertightly or airtightly coupled to each other.

[0052] As shown in Fig. 3, the rotor shaft (120) is a shaft member that has a rotor (121) that interacts with a stator (111) and is coupled to rotate around a rotation axis (RY) inside the housing (110).

[0053] That is, the rotor shaft (120) is another component of the motor that generates rotational force, and houses components such as a sealer shaft (130) that functions to spray a sealer (SL) therein. The rotor shaft (120) is a hollow shaft formed hollow. The rotor shaft (120) is coupled to rotate around a rotation axis (RY) inside the housing (110). The rotation axis (RY) means a virtual rotation axis (Rotation Y axis) that extends through the inside of the hollow rotor shaft (120) and becomes the center of rotation of the rotor shaft (120). At this time, the rotor shaft (120) can rotate while being supported by a bearing inside the housing (110).

[0054] In addition, the bearing is coupled to the outer surface of the rotor shaft (120) and can support the rotor shaft (120) so that it can rotate around the rotation axis (RY).

[0055] Meanwhile, in the present invention, a number of bearings are used to ensure smooth rotation, but only bearings with characteristic functions among the bearings are described in detail by assigning symbols, and the rest are described simply without assigning symbols.

[0056] The rotor shaft (120) has a rotor (121) arranged circumferentially on its outer periphery. At this time, the housing (110) accommodates the rotor shaft (120) equipped with the rotor (121). When power is supplied to the swirl dispenser device (100), the rotor (121) interacts with the stator (111) to generate a rotational force that rotates the rotor shaft (120). In this way, the swirl dispenser device (100) performs a motor function by the stator (111) and the rotor (121).

[0057]

[0058] As shown in Fig. 3, the sealer shaft (130) is a hollow shaft member having a first rotary port (131) in the shape of a sphere or ball fixed at one end through which the sealer (SL) is introduced and inserted into the interior of the housing (110) and a nozzle (133) for spraying the sealer (SL) formed at the other end and formed to penetrate the rotor shaft (120) along the rotation axis (RY).

[0059] That is, the sealer shaft (130) is formed hollow. The sealer shaft (130) receives the sealer (SL) supplied from the sealer channel (161) and sprays the sealer (SL) during the application process. The sealer shaft (130) has a length longer than the length along the rotation axis (RY) of the rotor shaft (120). The sealer shaft (130) is formed to penetrate the rotor shaft (120) along the rotation axis (RY), and the sealer shaft (130) is arranged inside the rotor shaft (120).

[0060] The sealer shaft (130) is arranged in the vertical height (lifting) direction in the form of a single overhanging beam with the other end being a free end within the housing (110). That is, the sealer shaft (130) is equipped with a first rotary member (131) in the shape of a sphere or ball (bal1) to enable three-dimensional rotation like a rotary ball at one end, and a nozzle (133) having a free end and spraying a sealer (SL) is formed at the other end.

[0061] That is, a nozzle (133) for spraying a sealer (SL) is formed at the other end, which is the free end of the sealer shaft (130). The sealer shaft (130) is configured so that the nozzle (133) protrudes from the rotor shaft (120). The other end of the sealer shaft (130) on which the nozzle (133) is formed protrudes from the housing (110) along the rotation axis (RY). The other end of the sealer shaft (130) protrudes from the lower end of the rotor shaft (120). The other end of the protruding sealer shaft (130) does not contact the housing (110).

[0062] In addition, the sealer shaft (130) is filled with a sealer (SL) in the hollow internal space so that the sealer (SL) can be ejected through an open nozzle (133) according to the internal pressure.

[0063] At this time, the nozzle (133) formed at the free end of the sealer shaft (130) is eccentric from the rotation axis (RY). Accordingly, when the rotor shaft (120) rotates, the nozzle (133) performs a circular motion centered on the rotation axis (RY) of the rotor shaft (120). The second holder (150) described later, which is arranged on the other side of the rotor shaft (120) and the sealer shaft (130), eccentricizes the nozzle (133).

[0064] Meanwhile, as shown in FIG. 1, the conventional sealer shaft (1300) has a fixed end (1310) and a free end (1320), and since the fixed end (1310) is fixed inside the housing (1100), the sealer shaft (1300) is bent along the rotation axis (RA) by the eccentric member (1400).

[0065] Accordingly, the conventional sealer shaft (1300) gradually bends from the fixed end (1310) toward the eccentric member (1400), and as the eccentric member (1400) rotates, it can be twisted and deformed while moving along a circular trajectory in a bent state with respect to the rotation axis (RA).

[0066] Due to this, when elastic energy accumulates inside the conventional sealer shaft (1300) and reaches a limit, it is plastically deformed or expressed, so that the sealer application is not uniform and is cut off or irregular like a staccato, making it impossible to achieve continuous and uniform application as shown in Fig. 2.

[0067] On the other hand, the sealer shaft (130) proposed by the present invention, as shown in (a) of FIG. 3, has a first rotary member (131) in the shape of a sphere or ball accommodated inside the housing (110) so as to be capable of three-dimensional point (ball) rotation without bending, thereby solving the problems of the prior art and allowing the sealer (SL) to be applied continuously and uniformly at regular intervals as shown in FIG. 2.

[0068] The first holder (140) is a member that holds one end of the sealer shaft (130), and can be installed on one side of the inside of the housing (110) coaxially with the rotation axis (RY) to provide a support space for accommodating the first rotary member (131).

[0069] In particular, the first holder (140) supports the first rotary member (131) so that it can rotate in a three-dimensional tilting manner. The first rotary member (131) is supported by receiving it in a concave shape, and the first rotary member (131) can be coupled so that it can rotate in a tilting manner.

[0070] In addition, as shown in (a) of FIG. 3, the first holder (140) has a pair of inductive members (141) that wrap around the outer surface of the first rotary member (131) at a predetermined height, as if spreading out two arms, and a ring member (142) having a cross-section in the shape of the letter "ㅓ" between the pair of inductive members (141) supports the outer side of the first rotary member (131), minimizing contact with the first rotary member (131) and reducing rotational resistance (friction), thereby enabling free three-dimensional rotation in the accommodated space.

[0071] The second holder (150) is fixed and coupled to the lower end (other end) of the rotor shaft (120), as shown in FIG. 3, and is fixed to rotate coaxially with the rotation axis (RY) of the rotor shaft (120).

[0072] The second holder (150) is a ring-shaped member that is coupled to the outer surface of the lower end of the rotor shaft (120), and supports the sealer shaft (130) by making slidable contact with it. The second holder (150) is configured to eccentrically move the sealer shaft (130) by a predetermined amount of eccentricity (EY) in a direction perpendicular to the rotation axis (RY).

[0073] That is, in the area of ​​the second holder (150), the central axis of the sealer shaft (130) is spaced apart from the rotation axis (RY) in a direction orthogonal to the rotation axis (RY). Accordingly, the sealer shaft (130) is inclined at a predetermined angle with respect to the rotation axis (RY) by the second holder (150). In addition, the nozzle (133) of the sealer shaft is eccentric from the rotation axis (RY) by an eccentricity amount (EY).

[0074] By the second holder (150), the sealer shaft (130) in contact with the second holder (150) is tilted eccentrically from the rotation axis (RY), and the nozzle (133) is eccentric by the eccentricity amount (EY).

[0075] When the rotor shaft (120) rotates around the rotation axis (RY), the second holder (150) rotates coaxially with the rotation axis (RY) of the rotor shaft (120). The sealer shaft (130) in contact with the second holder (150) is tilted eccentrically from the rotation axis (RY). In addition, the upper end (one end) of the sealer shaft (130) has a first rotary member (131) in the shape of a sphere or a ball, which is seated and accommodated inside the housing (1100). Accordingly, along with the rotation of the second holder (150), the nozzle (133) rotates circularly around the rotation axis (RY). In this circular movement of the nozzle (133), the sealer shaft (130) is moved along a circular trajectory while being tilted with respect to the rotation axis (RY). The radius of circular motion of the nozzle (133) may be the dimension of the eccentricity (EY) of the nozzle. Since the nozzle (133) rotates circularly around the rotation axis (RY) when the nozzle (133) is open, the swirl dispenser device (100) according to the first embodiment can apply the sealer (SL) in a swirl pattern.

[0076] Since the second holder (150) is adjacent to the free end (other end) of the sealer shaft (130), the sealer shaft (130) can be inclined at a predetermined angle from the first rotary member (131) toward the second holder (150). That is, the second holder (150) inclines the sealer shaft (130) with respect to the rotation axis (RY) so that the eccentricity (EY) of the sealer shaft (130) increases from the first rotary member (131) toward the second holder (150). As the second holder (150) rotates, the sealer shaft (130) can move along the trajectory of a cone or cone while being inclined with respect to the rotation axis (RA).

[0077] Accordingly, as shown in FIG. 3, the second holder (150) is fixed to the lower end of the rotor shaft (120) coaxially with the rotation axis (RY) to support the other side of the sealer shaft (130), and the sealer shaft (130) can be inclined along the rotation axis (RY) to eccentrically move the nozzle (133) from the rotation axis (RY).

[0078] In particular, the second holder (150) can be combined with a bearing (151) that supports the outer surface of the other side of the sealer shaft (130) but is eccentric in a direction orthogonal to the rotation axis (RY).

[0079] In addition, the second holder (150) tilts the sealer shaft (130) so that the eccentricity (EY) of the sealer shaft (130) increases from the first rotary member (131) toward the second holder (150), and the bearing (151) is configured to allow circular motion of the sealer shaft (130) centered on the rotation axis (RY), and the bearing (151) can be configured to allow conical motion of the sealer shaft (130) centered on the first rotary member (131).

[0080] That is, the second holder (150) includes a bearing (151) coupled with the outer surface of the sealer shaft (130). The bearing (151) is arranged to be eccentric in a direction orthogonal to the rotation axis (RY). The eccentricity (EY) of the bearing (151) can be set so that the nozzle (133) of the sealer shaft has the above-described eccentricity (EY). When the second holder (150) rotates around its rotation axis, the sealer shaft (130) performs a circular motion around the rotation axis (RY), and therefore, the bearing (151) is configured to allow such circular motion of the sealer shaft (130). As the rotor shaft (120) rotates, the sealer shaft (130) eccentrically rotates in a cone or conical shape by the second holder (150).

[0081] The sealer opening / closing unit (160) is a device that can open / close a sealer passage (161) formed to be connected to the sealer shaft (130) by a sealer valve (162), as shown in (b) of FIG. 3.

[0082] When applying the sealer, the sealer opening / closing part (160) opens the sealer passage (161) through the sealer valve (162) to spray the sealer (SL) through the nozzle (133), and when application of the sealer is stopped, the sealer (SL) inside the sealer shaft (130) is sucked in (like sniffing snot with the nose) to close the sealer passage (161), so that the pressure inside the sealer shaft (130) becomes lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out from the nozzle (133).

[0083] More specifically, as shown in (b) of FIG. 3, the sealer opening / closing unit (160) lowers the sealer valve (162) on the sealer passage (161) to spray the sealer (SL) through the open nozzle (133), thereby opening the sealed sealer passage (161) and providing spray pressure within the sealer shaft (130) to apply the sealer (SL) through the nozzle (133).

[0084] In addition, as shown in (b) of FIG. 3, when the sealer opening / closing part (160) raises the sealer valve (162) on the sealer passage (161) to stop the spraying of the sealer (SL) through the open nozzle (133), the sealer (SL) in the sealer shaft (130) is sucked in like sniffing snot with a nose, and when the open sealer passage (161) is closed, the pressure inside the sealer shaft (130) becomes lower than the atmospheric pressure, so that a negative pressure lower than the surroundings is generated, which can prevent the sealer (SL) from flowing out from the nozzle (133).

[0085] In particular, the conventional technology, as illustrated in FIG. 1, has a configuration in which a needle rod (1510) longer than the sealer shaft (1300) is inserted into the sealer shaft (1300) to open and close the nozzle (1330), so that the sealer within the sealer shaft (1300) is surrounded by the sealer shaft (1300) and the needle rod (1510) and thus has a large surface area, so that it is easily cooled or heated, and has a relatively small cross-sectional area, so that even a slight pressure fluctuation affects the sealer application, which is a very disadvantageous problem.

[0086] That is, in the conventional technology, a narrow and long needle rod (1510) like a needle is raised and lowered on the upper side of the nozzle (1330) to open and close, but it can easily become clogged even under a slight pressure, frequently break during sealer application, or easily cool down and cause the sealer to harden.

[0087] However, the sealer opening / closing unit (160) proposed by the present invention can effectively control the open nozzle (133) by controlling the sealer valve (162) that is spaced apart without being easily affected by temperature changes by the sealer (SL) filled in the space within the sealer shaft (130) acting as a buffer.

[0088] A swirl dispenser device (200) according to a second embodiment of the present invention is a device for applying a sealer (sealer or sealant) in a swirl form, as shown in FIGS. 4 and 5, and includes a housing (210), a rotor shaft (220), a sealer shaft (230), a first holder (240), a second holder (250), etc.

[0089] The housing (210) is applied with reference to the housing (110) mentioned above. The housing (210) has a stator (211) inside. The stator (211) receives power from a power source through a power connector (not shown) attached to the housing (210). Meanwhile, the housing (210) may be composed of a plurality of blocks for easy maintenance by assembling or disassembling, and may be watertightly or airtightly coupled to each other.

[0090] The rotor shaft (220) is applied with reference to the rotor shaft (120) mentioned above. As illustrated in FIG. 4, it is a shaft member that has a rotor (221) that interacts with a stator (211) and is coupled to the inside of the housing (210) so as to rotate around the rotation axis (RY). At this time, the rotor shaft (220) can be supported and rotated by a bearing within the housing (210). In addition, the bearing can be coupled to the outer circumferential surface of the rotor shaft (220) to support the rotor shaft (220) so as to rotate around the rotation axis (RY).

[0091] Meanwhile, in the present invention, a number of bearings are used to ensure smooth rotation, but only bearings with characteristic functions among the bearings are described in detail by assigning symbols, and the rest are described simply without assigning symbols.

[0092] The sealer shaft (230) is applied with reference to a part of the sealer shaft (130) mentioned above. As illustrated in Fig. 4, it is a hollow shaft member having a first rotary port (231) in the shape of a sphere or ball fixed at one end through which the sealer (SL) is introduced and inserted into the interior of the housing (210), and a nozzle (233) for spraying the sealer (SL) formed at the other end, and formed to penetrate the rotor shaft (220) along the rotation axis (RY).

[0093] The sealer shaft (230) receives the sealer (SL) supplied from the sealer oil (261) and sprays the sealer (SL) during the application process. The sealer shaft (230) has a length longer than the length along the rotation axis (RY) of the rotor shaft (220). The sealer shaft (230) is formed to penetrate the rotor shaft (220) along the rotation axis (RY), and the sealer shaft (230) is arranged inside the rotor shaft (220).

[0094] The sealer shaft (230) is arranged in the vertical height (lifting) direction in the form of a single overhanging beam with the other end being free within the housing (210). That is, the sealer shaft (230) is equipped with a first rotary member (231) in the shape of a sphere or ball to enable three-dimensional rotation like a rotary ball at one end, and a second rotary member (232) in the shape of a sphere or ellipsoid is formed to enable three-dimensional rotation on the other end closer to the other end.

[0095] In particular, the sealer shaft (230) proposed by the present invention, as shown in (a) of FIG. 4, has a first rotary member (231) in the shape of a sphere or ball accommodated inside the housing (210) so as to be capable of three-dimensional point (ball) rotation without bending, thereby solving the problems of the prior art and enabling continuous and uniform application of the sealer (SL) at regular intervals as shown in FIG. 2.

[0096] More specifically, the first rotary shaft (231) has an outer surface in the shape of a sphere or ball, and can freely rotate in three dimensions tilting like a joystick while being accommodated in the first holder (240), thereby solving the problem of uneven sealer application due to one end of the sealer shaft being fixed and bent in the past.

[0097] Furthermore, in order to prevent twisting or bending, etc. from occurring even when the sealer shaft (230) is relatively shortened, the second rotary member (232) has an outer surface in the shape of a sphere or ellipsoid, and can freely rotate in three dimensions tilting like a joystick while being accommodated in the second holder (250), thereby complementing the sealer shaft (130) of the first embodiment.

[0098] The sealer shaft (230) has a free end at the other end and a nozzle (233) for spraying a sealer (SL) is formed, and the sealer (SL) is filled in the hollow internal space so that the sealer (SL) can be sprayed through the nozzle (233) that is opened according to the internal pressure.

[0099] At this time, the nozzle (233) formed at the free end of the sealer shaft (230) is eccentric from the rotation axis (RY). Accordingly, when the rotor shaft (220) rotates, the nozzle (233) performs a circular motion centered on the rotation axis (RY) of the rotor shaft (220). The second holder (250) arranged on the other side of the rotor shaft (220) and the sealer shaft (230) eccentricizes the nozzle (233).

[0100] The first holder (240) is a member that holds one end of the sealer shaft (230), and as shown in (a) of FIG. 4, can be installed on one side of the inside of the housing (210) coaxially with the rotation axis (RY) to provide a support space for accommodating the first rotary member (231).

[0101] In particular, the first holder (240) supports the first rotary member (231) so that it can rotate in a three-dimensional tilting manner. The first rotary member (231) is supported by receiving it in a concave shape, and the first rotary member (231) can be coupled so that it can rotate in a tilting manner.

[0102] In addition, as shown in (a) of FIG. 4, the first holder (240) has a pair of inductive members (241) that wrap around the outer surface of the first rotary member (231) at a predetermined height, as if spreading out two arms, and a ring member (242) having a cross-section in the shape of the letter "ㅓ" between the pair of inductive members (241) supports the outer side of the first rotary member (231), minimizing contact with the first rotary member (231) and reducing rotational resistance (friction), thereby enabling free three-dimensional rotation in the accommodated space.

[0103] In addition, the first holder (240) can be modularized by a holder housing (243) that accommodates a guide member (241) and a ring member (242), and the guide member (241), the ring member (242), and the holder housing (243) can move as one unit.

[0104] The second holder (250) is fixed and coupled to the lower end (other end) of the rotor shaft (220), as shown in (a) of FIG. 5, and is fixed to rotate coaxially with the rotation axis (RY) of the rotor shaft (220).

[0105] The second holder (250) has a ring shape that is combined with the outer surface of the lower end of the rotor shaft (220) and supports the sealer shaft (230). The second holder (250) is configured to eccentrically move the sealer shaft (230) by a predetermined amount of eccentricity (EY) in a direction perpendicular to the rotation axis (RY).

[0106] In particular, the second holder (250) supports the second rotary member (232) so that it can rotate in three dimensions by tilting. The second rotary member (232) is supported by receiving it in a concave shape, but the second rotary member (232) is coupled so that it can rotate by tilting, and in conjunction with the first holder (240), provides flexibility so that the sealer shaft (230) is not twisted or deformed.

[0107] The upper end (one end) of the sealer shaft (230) has a first rotary member (231) in the shape of a sphere or ball, which is accommodated within the housing (210). Accordingly, along with the rotation of the second holder (250), the nozzle (233) rotates circularly around the rotation axis (RY). In this circular movement of the nozzle (233), the sealer shaft (230) moves along a circular trajectory while being inclined with respect to the rotation axis (RY).

[0108] When the nozzle (233) is open, the nozzle (233) rotates circularly around the rotation axis (RY), so the swirl dispenser device (200) according to the second embodiment can apply the sealer (SL) in a swirl pattern.

[0109] Accordingly, the second holder (250) is fixed to the lower end of the rotor shaft (220) coaxially with the rotation axis (RY), as shown in FIGS. 4 and 5, to support the other side of the sealer shaft (230), and the sealer shaft (230) can be inclined along the rotation axis (RY) to eccentrically move the nozzle (233) from the rotation axis (RY).

[0110] In particular, the second holder (250) supports the outer surface of the second rotary member (232) on the other side of the sealer shaft (230), and a bearing (251) that is eccentric in a direction orthogonal to the rotation axis (RY) can be coupled to slide in the internal up-and-down direction of the second holder (250), and the bearing (251) can slide within the second holder (250) along the up-and-down direction of the sealer shaft (230).

[0111] In addition, the bearing (251) is a double bearing, and as shown in (a) of FIG. 5, a groove (252) is formed on the inner surface to surround and accommodate the second rotary member (232) and enable rolling movement in the vertical direction.

[0112] That is, when rotating around the rotation axis of the second holder (250), the sealer shaft (230) eccentrically rotated by the second holder (250) in a cone or conical shape according to the rotation of the rotor shaft (220).

[0113] The sealer opening / closing unit (260) is applied with reference to the sealer opening / closing unit (160) mentioned above. As shown in (b) of Fig. 4, it is a device that can open / close a sealer passage (261) formed to be connected to the sealer shaft (230) by a sealer valve (262).

[0114] When applying the sealer, the sealer opening / closing part (260) opens the sealer passage (261) through the sealer valve (262) to spray the sealer (SL) through the nozzle (233), and when application of the sealer is stopped, the sealer (SL) inside the sealer shaft (230) is sucked in (like sniffing snot with the nose) to close the sealer passage (261), so that the pressure inside the sealer shaft (230) becomes lower than the atmospheric pressure, thereby generating a negative pressure lower than the surroundings, thereby preventing the sealer (SL) from flowing out from the nozzle (233).

[0115] The sealer opening / closing unit (260) proposed by the present invention can effectively control the sealer valve (262) that is spaced apart without being easily affected by temperature changes by the sealer (SL) filled in the space within the sealer shaft (230) acting as a buffer, so that the open nozzle (233) can be effectively blocked.

[0116] The expansion member (270) is a device that raises and lowers the height of the nozzle (233), as shown in (b) of Fig. 5, and can be directly controlled along the panel surface on which a gradient is formed without using a robot arm or the like.

[0117] That is, the expansion member (270) is installed as an extension to the housing (210) and supplies a fluid such as operating oil or air to the first flow path (171) and the second flow path (172), so that the first holder (240) can be raised and lowered. At this time, the first holder (240) can be raised and lowered up and down within the expansion member (270) while rotatably holding the first rotary member (231).

[0118] Here, when the fluid flows into the first flow path (171) and is discharged into the second flow path (172), the first holder (240) rises, and when the fluid flows into the second flow path (172) and is discharged into the first flow path (171), the first holder (240) descends.

[0119] Accordingly, the expansion member (270) elevates the first holder (240) that rotatably holds the first rotary member (231) and proportionally elevates the other side of the sealer shaft (230) on which the nozzle (233) is formed, thereby adjusting the height of the nozzle (233), and enables it to be operated at a set height on the panel to which the sealer is applied. At this time, the expansion member (270) can elevate the first holder (240) by being watertight or airtight inside the housing (210).

[0120] The above description is merely an example of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications, changes, and substitutions can be made without departing from the essential characteristics of the present invention.

[0121] Accordingly, the embodiments disclosed in the present invention and the attached drawings are not intended to limit the technical idea of ​​the present invention but to explain it, and the scope of the technical idea of ​​the present invention is not limited by these embodiments and the attached drawings.
