Description

Portable photocurable resin coating tool

Technical Field

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

Background

Conventionally, in various scenarios, ultraviolet curable resins have been used for joining members to each other. 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 (Dispenser). On the other hand, in a scene where manual operation is required, such as a repair site for various kinds of equipment, an application tool that can be carried around and can easily apply an ultraviolet curable resin with a so-called pen-like structure is used.

Such a portable coating tool is provided with an ultraviolet irradiation lamp integrally at the rear end side of the pen. After the coating, the rear end of the pen is turned over toward the object to be coated, and the ultraviolet irradiation lamp is directed to the coating region, and then the resin is cured by irradiating ultraviolet rays for a short time (for example, see patent document 1).

Technical problem

However, the conventional portable coating tool has a problem that after the ultraviolet curable resin is coated, the tool needs to be gripped again so as to exchange the front end and the rear end of the pen to irradiate the ultraviolet ray, and the operation efficiency is poor.

In particular, in the case where the object to be coated is coated while being held by one hand, when the pen is reversed after the completion of the operation of coating the ultraviolet curable resin and the ultraviolet irradiation lamp at the rear end is moved, the object to be coated must be released from one hand. There is a problem that the applied ultraviolet-curable resin drops during the period, or the application object must be irradiated with ultraviolet rays after the gripping posture of the object is adjusted again. In other words, the conventional portable coating tool has a problem that the resin cannot be cured simultaneously with the application of the ultraviolet curable resin.

The present invention has been made in view of such circumstances, and an object thereof is to provide a photocurable resin applicator that can achieve both portability and operability.

In the portable photocurable resin application tool, the variable angle holding structure holds the curing light irradiation section such that the optical axis is not parallel to a direction in which the discharge section discharges the photocurable resin in a state in which the variable angle holding structure is provided in the main body.

In the portable photocurable resin applicator, the holding portion is detachable from the main body, and the holding portion also serves as a base for the curing light irradiation portion in a state of being detached from the main body.

In the portable photocurable resin application tool, the angle-variable holding structure holds the cured-light irradiation section so that the optical axis is not perpendicular to a contact surface of the holding section that also serves as the base.

In the portable photocurable resin application tool, the angle-variable holding structure includes a first restriction portion that restricts movement of the curing light irradiation portion so that the curing light irradiation portion is held by the holding portion at a first angle.

In the portable photocurable resin application tool, the angle-variable holding structure may include a second regulating portion that regulates movement of the curing light irradiation portion such that the curing light irradiation portion is held by the holding portion at a second angle different from the first angle.

In the portable photocurable resin applicator, the first restriction portion is a recess or a projection that can be engaged with the curing light irradiation portion.

The portable photocurable resin applicator is characterized in that the variable angle holding structure includes a swing mechanism for swingably holding the curing light irradiation section.

The portable photocurable resin applicator is characterized by including a cap portion detachably provided on the main body so as to cover the discharge portion, and the cap portion detached from the main body is connectable to the holding portion detached from the main body.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows an overall configuration of a portable photocurable resin coating tool (hereinafter, referred to as a coating tool) 1 according to an embodiment of the present invention. The coating tool 1 includes a main body 10 to be held by a user, a cap 20, a holding portion 30, and a curing light irradiation portion 60.

As shown in fig. 3 a, the main body 10 includes a columnar (rod-shaped) container portion 12 that is formed into a pen shape, and a discharge portion 16 disposed at the axial distal end of the container portion 12. An engagement portion (cylindrical protrusion) 18 that can be engaged with the holding portion 30 is formed at the rear end of the container portion 12 in the axial direction. An ultraviolet-curable resin (photocurable resin) that can be cured by ultraviolet light (curing light) is stored in the container portion 12. The ultraviolet curable resin is dropped from the tip of the discharge portion 16 through a conduit not shown in the drawing.

The cap 20 is detachably provided to cover the discharge portion 16 of the main body 10. Here, the cover 20 has a hexagonal outer cross section to facilitate rotation by the fingertips of a user when attached and detached. The spare engaging portion 20A is formed at the protruding end of the lid portion 20, and the outer diameters of the spare engaging portion 20A and the engaging portion 18 of the main body 10 are made to coincide with each other. As a result, the backup engaging portion 20A can engage with the holding portion 30.

As shown in fig. 4, the curing light irradiation section 60 includes: a case 62 accommodating the button cell D therein; a light emitting section 64 disposed on the periphery of the case 62 and emitting ultraviolet rays; a positioning protrusion 66 formed on the periphery of the case 62 on the opposite side of the light emitting portion 64; and an on/off switch 67 disposed substantially at the center of the case 62. Note that, since the button cell D is housed inside, a part of the outer shape of the case 62 is formed in a disk shape, but here, as a result of further projecting the positioning protrusion 66 in the opposite direction to the light emitting portion 64, the case 62 has a substantially rhombic shape as a whole. A through hole 68 for attaching a strap or the like is formed near the positioning protrusion 66 of the housing 62.

As shown in fig. 2, the holding portion 30 is detachably provided at the rear end of the main body 10 and holds the curing light irradiation portion 60. The holding portion 30 includes a base 32 that can be fitted to the engagement portion 18 of the main body 10, and a pair of holding arms 40 that are provided upright on the base 32 in the axial direction.

The pedestal 32 is formed in a cylindrical shape having a hexagonal cross section to facilitate rotation thereof by the fingertips of a user during mounting and dismounting. The base 32 has a through hole 34 that penetrates in the axial direction, and one side of the through hole 34 is a recess for fitting with the engagement portion 18, and the other side is a recess for accommodating the light emitting portion 64 or the positioning protrusion 66 of the curing light irradiation portion 60 (see fig. 1). As shown in fig. 5, the surface of the pedestal 32 facing the main body 10 functions as a contact surface 32A to be placed on a table or the like when detached.

Returning to fig. 2, the pair of holding arms 40 are disposed at an interval similar to the thickness T (see fig. 4 a) of the housing 62 of the curing light irradiation section 60, and can hold the curing light irradiation section 60 so as to sandwich the curing light irradiation section 60. Each holding arm 40 has a holding surface 42 facing the holding arm on the opposite side, and the holding surface 42 is brought into contact with a disc-shaped flat surface of the housing 62 of the curing light irradiation section 60. A plurality of (4 in this case) projections 44 are formed on the holding surface 42. These protrusions 44 are engaged with the peripheral edge of the case 62 of the curing light irradiation section 60 to regulate the holding posture of the curing light irradiation section 60. An opening 40A is formed in the center of the holding arm 40, and the switch 67 of the held curing light irradiator 60 faces the opening 40A. Therefore, the switch 67 can be operated through the opening 40A by the holding arm 40 in a state where the curing light irradiation section 60 is held.

Next, a variable angle holding structure formed between the holding portion 30 and the curing light irradiation portion 60 will be described. The angle-variable holding structure can hold and position the curing light irradiation section 60 in a plurality of postures in which the optical axes of ultraviolet light irradiation of the curing light irradiation section 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. The first posture (first angle) is such that the optical axis of the ultraviolet light is perpendicular to the contact surface 32A. At this time, the peripheral edge of the housing 62 of the curing light irradiation section 60 is regulated by the plurality of (4 in this case) protrusions 44 formed around the holding arm 40, and the positioning protrusion 66 of the curing light irradiation section 60 is engaged with the through hole 34 of the base 32. Therefore, these projections 44, through holes 34, positioning projections 66, and the like serve as first regulating portions for maintaining the first posture of the curing light irradiation section 60. In the first posture, the optical axis of the light emitting portion 64 is substantially parallel to the direction (axial direction) in which the discharge portion 16 discharges the ultraviolet curable resin in the state of being attached to the main body 10.

In fig. 5 (B), 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 desk or the like. The second posture (second angle) is such that the optical axis of the ultraviolet ray is not perpendicular (parallel here) to the contact surface 32A. At this time, the periphery of the case 62 of the curing light irradiation section 60 is restricted by the plurality of (here, 4) projections 44 formed around the holding arm 40. As described above, since the periphery of the case 62 of the cured light irradiation section 60 has a non-perfect-circle diamond shape, the periphery is surrounded by the plurality of projections 44 and is engaged with the periphery of the case 62 in the circumferential direction. Therefore, the non-circular peripheral shape of the projection 44 and/or the housing 62 serves as a second regulating portion for maintaining the second posture. In the second posture, the optical axis of the light emitting portion 64 is not parallel to the direction (axial direction) in which the discharge portion 16 discharges the ultraviolet curable resin in the state of being attached to the main body 10.

As shown in fig. 5, the holding portion 30 also serving as a pedestal can fix the curing light irradiation portion 60 in a space, and the user can freely use both hands during irradiation. As a result, the ultraviolet curable resin can be applied to the object to be coated while holding the object to be coated with one hand and holding the main body 10 with the other hand, and the ultraviolet rays can be irradiated. Therefore, when it is necessary to continuously cure the ultraviolet curable resin while applying it, the convenience is extremely high.

In particular, as shown in fig. 5B, the holding portion 30 holds the curing light irradiation portion 60 so that the optical axis of the ultraviolet ray is not vertical (horizontal direction in this case), and thus even if the ultraviolet curable resin falls to the table side during the application process, the ultraviolet curable resin does not adhere to the light emitting portion 64 of the curing light irradiation portion 60.

As shown in fig. 6 (a), when the height at which the holding portion 30 holds the curing light irradiation portion 60 is insufficient, the spare engagement portion 20A of the lid portion 20 may be connected to the through hole 34 of the holding portion 30, and the lid portion 20 may also function as a pedestal. As shown in fig. 6 (B), the curing light irradiation section 60 may be fixed in the second posture with the holding section 30 attached to the main body 10, and ultraviolet rays may be irradiated to the object to be coated.

In the above embodiment, the holding portion 30 and the lid portion 20 are illustrated as separate bodies, but the holding portion 30 may also serve as a lid portion as shown in fig. 7, for example.

In the above embodiment, the case where the projection 44 of the holding arm 40 is engaged with the peripheral edge of the housing 62 of the curing light irradiation section 60 has been described as an example, but the present invention is not limited thereto. For example, as shown in fig. 8 (a) and (B), a pair of projections 44 facing each other between the pair of holding arms 40 may be engaged with a pair of recesses 62A formed in the housing 62 of the curing light irradiation section 60. As shown in fig. 8C, the pair of protrusions 44 and the pair of recesses 62A engaged with each other function as a swing mechanism (swing shaft) for swingably holding the curing light irradiation part 60. As a result, the second posture (second angle) of the curing light irradiation section 60 can be freely adjusted. As shown in fig. 8 (D), if the light emitting section 64 or the positioning protrusion 66 of the curing light irradiation section 60 is accommodated in the through hole 34 of the holding section 30, the function of the swing mechanism is restricted and the swing mechanism is positioned in the first posture. 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.

Further, for example, as shown in fig. 8 (E), the discharge portion 16 preferably further includes an auxiliary nozzle 16A, and the auxiliary nozzle 16A preferably has a slit-shaped opening for enlarging the application range of the ultraviolet curable resin. As a result, for example, as shown in fig. 8 (F), the ultraviolet curable resin can be cured by irradiating ultraviolet light through the curing light irradiation section 60 while applying the ultraviolet curable resin over a wide range on the surface of the sheet-like object to be coated.

In the above embodiment, the case where the projection 44 is formed on the holding arm 40 side and the recess 62A is formed in the curing light irradiation section 60 as the regulating section for regulating the holding posture of the curing light irradiation section 60 has been described as an example, but the present invention is not limited to this. For example, the relationship of the projections and the depressions may be reversed, or the engaging structure and/or the engaging shape may be set to various structures and/or shapes. 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 the curing light irradiation units to each other in other shapes.

In the above embodiment, the configuration in which the pair of holding arms 40 of the holding portion 30 is sandwiched from the direction of the thickness T of the housing 62 of the curing light irradiation portion 60 has been illustrated, but the present invention is not limited to this. For example, as shown in fig. 9, the housing 62 may be sandwiched by the pair of holding arms 40 in the width direction W. Here, a pair of projections 62B are formed on both sides of the housing 62 in the width direction, and a pair of recesses (grooves) 45 that accommodate the projections 62B are formed near the front ends of the pair of holding arms 40. An engagement portion 45A for preventing the projection 62B from coming off is provided in the recess 45 in a projecting manner. As shown in fig. 9 (C), the pair of protrusions 62B and the pair of recesses 45 engaged with each other function as a swing mechanism for swingably holding the curing light irradiation section 60. As a result, the second posture (second angle) of the curing light irradiation section 60 can be freely adjusted.

In the above-described embodiment, the structure in which the curing light irradiation part is held by the pair of holding arms is exemplified, but the present invention is not limited to this, and the curing light irradiation part 60 may be positioned by fitting it into a single holding arm. Although the ultraviolet curable resin is exemplified here, the present invention can also be applied to a photocurable resin that is cured by light other than ultraviolet light.

The portable photocurable resin applicator according to the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
