DETAILED DESCRIPTION OF THE INVENTION

[0011] Next, the resin curing auxiliary device according to the present invention will be described below with reference to the accompanying drawings, showing preferred embodiments thereof. Note that the embodiments and drawings described below are intended to exemplify some of the embodiments of the present invention, and are not intended to be used for the purpose of limiting the scope of the present invention to these configurations, and can be modified as appropriate within the scope of the gist of the present invention.

[0012] 1, the resin curing auxiliary tool 20 according to the embodiment includes a housing 22, a rotation drive unit 24 arranged inside the housing 22, and a holder 40 that is detachably connected to a rotation shaft 26 of the rotation drive unit 24 that protrudes outside the housing 22 and that holds an item 10 (see FIG. 4). The resin curing auxiliary tool 20 includes a power supply source 28, such as a dry cell or a storage battery, that is arranged inside the housing 22 and supplies power to the rotation drive unit 24, such as an electric motor, and a switch 30 that is provided on the outer surface of the housing 22 and that drives or stops the rotation drive unit 24.

[0013] The resin curing auxiliary tool 20 is used when curing an ultraviolet-curable resin 12 (see FIGS. 4(a) and (b)) attached to an article 10 with ultraviolet light emitted from an ultraviolet light 14 (see FIG. 4(b)), and by rotating the article 10 held in the holding part 40, the entire circumference of the article 10 can be exposed to the ultraviolet light from the ultraviolet light 14. The resin curing auxiliary tool 20 is small and light enough to be held in one hand, and can be used by a user holding it in one hand (see FIG. 4(a)) or by placing it on an installation surface 16 such as a desk or stand (see FIG. 4(b)).

[0014] As shown in FIG. 1, the housing 22 is a rectangular box (a rectangular parallelepiped in the embodiment). The housing 22 can be self-standing by placing the flat bottom 22a on a flat installation surface 16 (see FIG. 4(b)), such as a desk or table. The surface of the bottom 22a and the surface opposite to the surface of the bottom 22a are the largest of the six surfaces of the housing 22. The rotation shaft 26 of the rotation drive unit 24 protrudes outward from one surface of the housing 22 other than the bottom 22a. In the embodiment, the rotation shaft 26 protrudes in the longitudinal direction of the housing 22 from one of the four side surfaces rising from the bottom 22a, which is aligned along the shorter side of the housing 22. Furthermore, the rotation shaft 26 is positioned at an upper position on the side surface of the housing 22, and the resin curing auxiliary device 20 can be supported at a position separating the article 10 from the installation surface 16. The tip of the rotating shaft 26 is cylindrical, and a female screw 26a is provided on the inner peripheral surface of the rotating shaft 26 (see FIG. 2). In the embodiment, the housing 22 has one side surface from which the rotating shaft 26 protrudes and the other side surface opposite the other side surface formed flat, and the other side surface can be placed on the installation surface 16 so that the housing 22 can stand on its own with the rotating shaft 26 facing upward.

[0015] As shown in FIG. 1, the holding unit 40 is detachably connected to the tip of the rotating shaft 26. The holding unit 40 has a male thread 40a that screws into the female thread 26a of the rotating shaft 26, and the holding unit 40 and the rotating shaft 26 are connected by a threaded connection using the male thread 40a and the female thread 26a (see FIG. 2). By connecting the holding unit 40 and the rotating shaft 26 by a threaded connection in this manner, the holding unit 40 can be easily and reliably attached to the rotating shaft 26. The holding unit 40 rotates around the same axis as the rotating shaft 26 as the rotating shaft 26 is rotated by the rotation drive unit 24. The rotation speed of the holding unit 40 by the rotation drive unit 24 is set to a low speed that prevents the ultraviolet-curable resin 12 applied to the article 10 from scattering.

[0016] As shown in Fig. 1, the holding unit 40 is a pinch clip having two opening / closing pieces 44 pivotally supported on a shaft 42 and a spring (not shown) that biases gripping portions 44a provided at one end of the two opening / closing pieces 44 toward each other. In the holding unit 40, the gripping portions 44a open when operation portions 44b provided on the opposite sides of the two opening / closing pieces 44 from the gripping portions 44a are brought closer together (see the two-dot chain lines in Fig. 1(a)). When the user releases the operation portions 44b, the spring biases the gripping portions 44a to close (see the solid lines in Fig. 1(a)). In this way, the holding unit 40 can hold or release the item 10 at the gripping portions 44a by manually operating the operation portions 44b.

[0017] As shown in FIGS. 1 and 3, the holding unit 40 has a cover 46 detachably disposed on the gripping portion 44a of the holding unit 40 that grips the article 10. The covers 46 are attached to the gripping portions 44a provided at the tips of the opening / closing pieces 44, respectively, and the covers 46 come into contact with each other when the gripping portions 44a are closed. The covers 46 are made of rubber, and silicone rubber is preferred among rubbers to which the ultraviolet-curable resin 12 does not easily adhere. Note that, when the cover 46 is removed, the gripping portions 44a are formed with mountain-shaped teeth 44c, and when the gripping portions 44a are closed, the teeth 44c engage with each other (see FIG. 3). In this way, the holding unit 40 has the detachable covers 46 disposed on the gripping portions 44a of the article 10, so that the presence or absence of the covers 46 can be selected depending on the article 10 to be held.

[0018] An example of how to use the resin curing auxiliary tool 20 described above will now be described. First, the item 10 is held by the holding part 40. By holding the housing 22, the item 10 is immersed in the ultraviolet-curable resin 12 contained in the container 18, thereby adhering the ultraviolet-curable resin 12 to the surface of the item 10 (see FIG. 4(a)). Next, the item 10 held by the holding part 40 of the resin curing auxiliary tool 20 is exposed to ultraviolet light emitted from the ultraviolet light 14. At this time, the rotation drive part 24 of the resin curing auxiliary tool 20 is driven to rotate the holding part 40, thereby rotating the item 10 held by the holding part 40 (see FIG. 4(b)). By rotating the item 10 in this manner, ultraviolet light can be applied efficiently and evenly to the entire item 10, thereby efficiently curing the ultraviolet-curable resin 12 applied to the surface of the item 10. The resin curing auxiliary tool 20 reduces or eliminates the need for the user to change the orientation of the article 10 relative to the ultraviolet light 14, thereby significantly reducing the burden on the user during the ultraviolet curing resin curing process.

[0019] The resin curing auxiliary tool 20 can stand on its own by placing the bottom 22a of the housing 22 on the installation surface 16, so the user does not need to hold the housing 22 when curing the ultraviolet-curable resin 12, reducing the burden on the user during the ultraviolet-curable resin curing work. Furthermore, since the holding part 40 of the resin curing auxiliary tool 20 is detachable from the rotating shaft 26, if the holding part 40 becomes dirty due to the work of attaching the ultraviolet-curable resin 12 to the article 10, the holding part 40 can be easily replaced or removed from the rotating shaft 26 for easy cleaning.

[0020] (Example of change) The present invention is not limited to the above-mentioned matters, but may be, for example, as follows: Note that the present invention is not limited to the specific descriptions of the embodiment and the following modified examples. (1) The connection structure between the rotating shaft and the holding part is not limited to the screw connection as in the embodiment, but may be other connection structures, such as a structure in which one of the rotating shaft or the holding part is pressed into a hole provided in the other, or a pin connection in which a pin is inserted into a hole provided in one of the rotating shaft or the holding part and then inserted into the other. (2) In the embodiment, the power supply source is built into the housing, but this is not limiting and the device may be connected to an external power source such as a household power source.
