Description

  The present invention relates to a portable applicator for applying a photocurable resin such as an ultraviolet curable resin.

  Conventionally, an ultraviolet curable resin has been used in joining various members in various situations. In a mass production assembly process in a factory, a large amount of ultraviolet curable resin is automatically and continuously applied using a so-called dispenser. On the other hand, an applicator that is portable and can be easily applied with an ultraviolet curable resin with a so-called pen structure is used in scenes that require manual work, such as repair sites for various devices.

  In this type of portable applicator, an ultraviolet irradiation lamp is integrally provided on the rear end side of the pen. After the application, the rear end of the pen is reversed on the object to be applied, the ultraviolet irradiation lamp is opposed to the application area, and then the ultraviolet light is irradiated and cured in a short time (see, for example, Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  In FIG. 1, the whole structure of the portable photocurable resin applicator (henceforth an applicator) 1 which concerns on embodiment of this invention is shown. The applicator 1 includes a main body 10 held by a user, a cap unit 20, a holding unit 30, and a curing light irradiation unit 60.

  As shown in FIG. 3A, the main body 10 includes a columnar (rod-shaped) tank portion 12 that is a pen type, and a discharge portion 16 that is disposed at the tip of the tank portion 12 in the axial direction. At the rear end of the tank portion 12 in the axial direction, an engaging portion (columnar protrusion) 18 that can be engaged with the holding portion 30 is formed. In the tank portion 12, an ultraviolet curable resin (photocurable resin) that can be cured by ultraviolet rays (curing light) is stored. This ultraviolet curable resin is dropped from the tip of the discharge part 16 through a conduit (not shown).

  The cap part 20 is detachably provided so as to cover the discharge part 16 of the main body 10. Here, the outer shape is a hexagonal cross section, and it is easy to rotate with the fingertip of the user during detachment. Note that a preliminary engagement portion 20A is formed at the protruding end of the cap portion 20, and the outer diameters of the preliminary engagement portion 20A and the engagement portion 18 of the main body 10 are made to coincide with each other. As a result, the preliminary engagement portion 20 </ b> A can be engaged with the holding portion 30.

  As shown in FIG. 4, the curing light irradiation unit 60 includes a housing 62 that houses the button battery D therein, a light emitting unit 64 that is disposed on the periphery of the housing 62 and irradiates ultraviolet rays, and a housing 62. It has a positioning projection 66 formed on the opposite side to the light emitting unit 64 at the periphery, and an ON / OFF switch 67 disposed at the approximate center of the housing 62. Note that a part of the outer shape of the housing 62 has a disk shape because the button battery D is accommodated therein, but here, the positioning projection 66 further protrudes in the opposite direction with respect to the light emitting portion 64. As a result, when viewed as a whole, a substantially rhombus shape is obtained. A through hole 68 for attaching a strap or the like is formed near the positioning projection 66 in the housing 62.

  As shown in FIG. 2, the holding unit 30 is detachably provided at the rear end of the main body 10 and holds the curing light irradiation unit 60. The holding portion 30 includes a pedestal 32 that can be fitted to the engaging portion 18 of the main body 10, and a pair of holding arms 40 that are erected in the axial direction with respect to the pedestal 32.

  The pedestal 32 is a column having an outer shape of a hexagonal cross section, and can be easily rotated by a user's fingertip during detachment. The pedestal 32 has a through hole 34 penetrating in the axial direction. One side of the through hole 34 serves as a recess for fitting with the engaging portion 18, and the other side is a light emitting portion of the curing light irradiation unit 60. 64 or a recess for accommodating the positioning projection 66 (see FIG. 1). As shown in FIG. 5, the surface of the pedestal 32 that faces the main body 10 functions as a seating surface 32A when placed on a table or the like when detached.

  Returning to FIG. 2, the pair of holding arms 40 are arranged so that the distance between them is approximate to the thickness T (see FIG. 4A) of the casing 62 of the curing light irradiation unit 60. It can hold | maintain so that the irradiation part 60 may be inserted | pinched. Each holding arm 40 has a holding surface 42 facing the counterpart holding arm, and this holding surface 42 is brought into contact with the disk-shaped plane of the casing 62 of the curing light irradiation unit 60. In addition, a plurality (here, four) of protrusions 44 are formed on the holding surface 42. These protrusions 44 regulate the holding posture of the curing light irradiation unit 60 by engaging with the peripheral edge of the casing 62 of the curing light irradiation unit 60. An opening 40A is formed at the center of the holding arm 40, and the switch 67 of the curing light irradiation unit 60 to be held faces the opening 40A. Therefore, the switch 67 can be operated through the opening 40A while the curing light irradiation unit 60 is held by the holding arm 40.

  Next, the variable angle holding structure formed between the holding unit 30 and the curing light irradiation unit 60 will be described. The variable angle holding structure enables the curing light irradiation unit 60 to be held and positioned in a plurality of postures such that the optical axes of the ultraviolet irradiation of the curing light irradiation unit 60 are different from each other.

  Specifically, in FIG. 5A, the holding unit 30 holds the curing light irradiation unit 60 in a first posture (first angle) in a state where the holding unit 30 is placed on a table or the like. In this first posture (first angle), the optical axis of the ultraviolet light is perpendicular to the seating surface 32A. At this time, the plurality of (four in this case) protrusions 44 formed around the holding arm 40 regulate the peripheral edge of the casing 62 of the curing light irradiation unit 60, and the curing light enters the through hole 34 of the base 32. The positioning protrusion 66 of the irradiation unit 60 is engaged. Accordingly, the projections 44, the through holes 34, the positioning projections 66, and the like serve as a first restricting portion for maintaining the first posture of the curing light irradiation unit 60. The first posture is a state in which the optical axis of the light emitting unit 64 is substantially parallel to the discharge direction (axial direction) of the ultraviolet curable resin by the discharge unit 16 in a state of being mounted on the main body 10. .

  In FIG. 5B, the holding unit 30 holds the curing light irradiation unit 60 in the second posture (second angle) in a state where the holding unit 30 is placed on a table or the like. In this second posture (second angle), the optical axis of the ultraviolet light is non-perpendicular (here parallel) to the seating surface 32A. At this time, the peripheral edge of the casing 62 of the curing light irradiation unit 60 is regulated by a plurality (four in this case) of protrusions 44 formed around the holding arm 40. As described above, the peripheral edge of the casing 62 of the curing light irradiation unit 60 has a rhombus shape that is a non-circular shape. Match. Accordingly, these protrusions 44 and the peripheral shape of the non-circular circle in the housing 62 become the second restricting portion for maintaining the second posture. The second posture is a state in which the optical axis of the light emitting unit 64 is non-parallel to the discharge direction (axial direction) of the ultraviolet curable resin by the discharge unit 16 in a state of being mounted on the main body 10. .

  As shown in FIG. 5, the holding unit 30 also serving as a pedestal can fix the curing light irradiation unit 60 in the space, and both hands of the user are free during irradiation. As a result, it is possible to irradiate ultraviolet rays while holding the body 10 with one hand while holding the main body 10 with the other hand and applying the ultraviolet curable resin to the application object. Therefore, it is extremely convenient when it is necessary to continuously cure while applying the ultraviolet curable resin.

  In particular, as shown in FIG. 5B, the holding unit 30 holds the curing light irradiation unit 60 so that the optical axis of the ultraviolet light is in a non-vertical direction (here, the horizontal direction). Even if the ultraviolet curable resin falls to the table side, the ultraviolet curable resin does not need to adhere to the light emitting portion 64 of the curable light irradiation unit 60.

  As shown in FIG. 6A, when the holding height of the curing light irradiation unit 60 by the holding unit 30 is insufficient, the preliminary engagement portion of the cap unit 20 with respect to the through hole 34 of the holding unit 60. 20A may be connected and the cap part 20 may also function as a base. Moreover, as shown in FIG. 6 (B), the curing light irradiation unit 60 may be fixed in the second posture while the holding unit 30 is mounted on the main body 10, and the application target may be irradiated with ultraviolet rays. .

  In the above-described embodiment, the case where the holding unit 30 and the cap unit 20 are separated is illustrated. However, for example, as illustrated in FIG. 7, the holding unit 30 may also serve as the cap unit.

  Moreover, although the case where the protrusion 44 of the holding arm 40 is engaged with the peripheral edge of the casing 62 of the curing light irradiation unit 60 is illustrated in the above embodiment, the present invention is not limited to this. For example, as shown in FIGS. 8A and 8B, the pair of protrusions 44 facing each other between the pair of holding arms 40 are engaged with a pair of recesses 62A formed in the casing 62 of the curing light irradiation unit 60. May be combined. As shown in FIG. 8C, the pair of protrusions 44 and the pair of recesses 62A that engage with each other function as a swinging mechanism (swinging shaft) that holds the curing light irradiation unit 60 swingably. As a result, the second posture (second angle) of the curing light irradiation unit 60 can be freely adjusted. As shown in FIG. 8D, if the light emitting part 64 or the positioning projection 66 of the curing light irradiation part 60 is accommodated in the through hole 34 of the holding part 30, the function of the swing mechanism is restricted, and Positioned in one position. Note that the switch 67 of the curing light irradiation unit 60 is preferably disposed on the periphery of the housing 62 so as not to interfere with the pair of holding arms 40.

  Furthermore, for example, as shown in FIG. 8 (E), it is also preferable that the discharge unit 16 includes an attachment nozzle 16A having a slit-like opening for extending the application range of the ultraviolet curable resin. In this case, for example, as shown in FIG. 8 (F), the ultraviolet ray curable resin is applied over a wide area on the surface of the sheet-like application object, and at the same time, the ultraviolet ray is irradiated by the curing light irradiation unit 60. Thus, it can be cured.

  Furthermore, in the said embodiment, although the processus | protrusion 44 is formed in the holding | maintenance arm 40 side and the recessed part 62A is formed in the hardening light irradiation part 60 as a control part which controls the holding attitude | position of the hardening light irradiation part 60, it illustrates. However, the present invention is not limited to this. For example, the relationship between the concaves and convexes can be reversed, and the engagement structure and engagement shape can be variously set. For example, a recess may be formed on the holding arm 40 side and a protrusion may be formed on the curing light irradiation unit 60 side to engage with each other. The holding posture of the curing light irradiation unit 60 may be regulated by fitting with each other by other shapes.

  Furthermore, in the above embodiment, the structure in which the pair of holding arms 40 of the holding unit 30 is clamped from the direction of the thickness T of the casing 62 of the curing light irradiation unit 60 is illustrated, but the present invention is not limited to this. For example, as shown in FIG. 9, the housing 62 may be sandwiched from the width direction W by a pair of holding arms 40. Here, a pair of protrusions 62B are formed on both sides in the width direction of the housing 62, while a pair of recesses (concave grooves) 45 for accommodating the protrusions 62B are formed near the tips of the pair of holding arms 40. To do. The recess 45 is provided with an engaging portion 45A for preventing the protrusion 62B from coming off. As shown in FIG. 9C, the pair of protrusions 62B and the pair of recesses 45 that are engaged with each other function as a swinging mechanism that swingably holds the curing light irradiation unit 60. As a result, the second posture (second angle) of the curing light irradiation unit 60 can be freely adjusted.

  In addition, in the said embodiment, although the structure which hold | maintains a holding part with a pair of holding arm was illustrated, this invention is not limited to this, The hardening light irradiation part 60 is made to fit with respect to a single holding arm. You may position with. In addition, although an ultraviolet curable resin is illustrated here, the present invention can also be applied to a photocurable resin that is cured by light other than ultraviolet rays.

  In addition, the portable photocurable resin applicator of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
