Description

Multi Light Curing Apparatus {Muti-Light Curing Apparatus}

The present invention relates to a multiple photopolymerization apparatus capable of photopolymerizing a resin under various wavelengths, and more specifically, to produce a product by curing various resins by photopolymerization, such as in the dental and pore fields. It provides a photopolymerization apparatus that can be used for all star polymerization wavelengths.

As a representative field for manufacturing a product by curing (photopolymerization) of various photopolymerizable resins as needed, the dental and pore fields may be mentioned. For example, in the dental field, a personal tray photopolymerization apparatus means a device for curing a photopolymerizable resin for the manufacture of a personal tray. From the conventional powder type (chemically polymerized) personal tray products, as the demand for photopolymerized personal tray resins gradually increases, the demand for personal tray photopolymerization devices is also increasing.

1 schematically shows a general structure of a photopolymerization apparatus 100 of a resin for manufacturing a conventional personal tray (hereinafter referred to as "personal tray resin"). Looking at the structure of the photopolymerization apparatus 100, a lamp 300 that emits light (light) for the photopolymerization is mounted on the upper inside of the housing 200, the turntable 400, the tray resin is placed on the inner bottom In addition, a timer 500 for controlling the operation time of the lamp 200 is installed outside the housing 200. When the personal tray resin is placed on the turntable 400 and the timer 200 is operated while the housing 200 is sealed, the curing (photopolymerization) reaction of the resin occurs by the light emitted from the lamp 300. The wavelength of the light emitted from the lamp 300 varies depending on the manufacturer of the photopolymerization apparatus 100, and generally has a wavelength in the ultraviolet region. Therefore, the photopolymerization of the corresponding resin occurs due to the wavelength of a specific region.

On the other hand, while the demand for personal trays in dental hospitals and laboratories is gradually increasing, these dental and laboratory laboratories generally do not have a curing device for curing resins to produce personal trays. This is because of the cost burden of overlapping investment in which a curing apparatus for a personal tray resin as described above is separately provided in addition to the general resin curing apparatus. In particular, in the case of a dental clinic, even if a general resin curing apparatus is retained, the individual tray resin cannot be cured, and often a laboratory is intentionally asked to manufacture a personal tray. Therefore, since both curing devices are required to cure the personal tray resin and the general resin, there is an unnecessary problem in economic and working time.

On the other hand, dental materials manufacturers tend to supply dental hospitals and laboratories using their own unique catalysts. Since these products are generally different in the resin curing (photopolymerization) wavelength range of each product, each product must have a separate device for curing the resin.

Therefore, there is a very high need for a device capable of curing all of the manufacturer-specific products of dental materials by one curing device.

Therefore, the present invention aims to solve these problems of the prior art and technical problems that have been requested from the past.

That is, an object of the present invention is to provide a multiple photopolymerizer, in particular a photopolymerizer for a personal tray resin, which can cure (photopolymerize) resins that are photopolymerized at different wavelengths by one device.

In order to achieve this object, the multiple photopolymerization apparatus of the present invention,

(A) a hermetically sealed housing having a reflector on at least one side thereof;

(B) a lamp in the visible region and a lamp in the ultraviolet region mounted on the inner upper end of the housing; And,

And (C) a turntable mounted to the inner bottom of the housing and positioned below the lamps.

The multi-photopolymerization apparatus of the present invention can be used for curing of various resins in which the photopolymerization reaction occurs in the visible or ultraviolet region, and can further accelerate the curing process by the heat of emission from the visible region lamp.

The housing serves to protect internal components from the outside and to prevent light (light) from being emitted to the outside during the curing process. The interior of the housing is preferably provided with a reflector over the entire surface, so that the light generated from the lamp can be reflected into the device to increase the light irradiation efficiency as well as induce an even curing reaction to the material.

The light (light) emitted from the lamp in the visible region and the lamp in the ultraviolet region covers a wavelength region of approximately 300 to 700 nm, and may be in the form of a bar or a bulb. In some cases, each of the lamps may be used in more than one number, and preferably, a pair of lamps in the ultraviolet region are positioned to the left and right of the lamp in the visible region.

The lamp in the visible light region is preferably a lamp that emits light in the visible light region of 350 to 500 nm, and also emits light in a part of the ultraviolet region. Preferred examples of such lamps include halogen lamps having a power consumption of approximately 10 to 300 W. Since the halogen lamp generates heat during light emission, as described above, the heat of luminescence acts as heat of polymerization to promote the curing reaction of the resin. Halogen lamps are provided to be spaced at least 5 cm or more from the curing resin on the turntable and perform forced cooling by the blowing fan. This is because when the distance between the halogen lamp and the curing resin is too close or when excessive heat is provided, physical properties may be deteriorated due to shrinkage of the product due to strong heat.

The ultraviolet lamp is preferably a lamp that emits light in the ultraviolet region of 320 to 400 nm, it is possible to use a general ultraviolet light bulb having a power consumption of approximately 5 to 100W. Commercialized examples of such light bulbs include Osram UV light bulbs, Philips UV light bulbs, and the like.

The turntable rotates at a constant speed to induce an even curing reaction, and preferably has a reflector mounted on an upper surface such as an inner surface of the housing to increase light irradiation efficiency.

Preferably, the apparatus may further include a control unit for setting the operation time of the device, the type and intensity of the operation lamp. The control unit, unlike the timer in the conventional apparatus merely serves to set the operating time, lamp intensity, etc., the type of lamp to be operated according to the type of tray resin, that is, whether to operate the lamp in the visible light region. It is possible to arbitrarily set whether to operate the lamp in the ultraviolet region or to operate both lamps.

Hereinafter, a photopolymerization apparatus according to an embodiment of the present invention will be described in more detail with reference to the drawings, but the scope of the present invention is not limited thereto.

It protrudes on the back of the member 610. The central axis of the halogen lamp 310 is slightly spaced apart from the center of the turntable 410, so that the direction of light irradiation may be evenly provided to a personal tray resin (not shown) on the turntable 410. In addition, since the reflector is covered on the halogen lamp 310 itself, the light irradiation efficiency is further increased. When the personal tray resin is placed on the turntable 410 and the power is operated while the housing 210 is covered, the turntable 410 rotates at a constant speed, and the light from the halogen lamp 310 and the ultraviolet light bulb 315 is emitted. ) Is emitted to cause a curing (photopolymerization) reaction of the resin.

On the other hand, since the halogen lamp 310 generates heat when emitting light, by appropriately controlling it, it is possible to promote curing while preventing damage to the tray product. For this thermal control, the air introduced from the air inlet 216 installed on the upper side of the housing enters the inside of the reactor through a plurality of inlets 217 perforated around the halogen lamp 310, and the halogen lamp While removing the heat of luminescence of 310, some are delivered to the personal tray resin on the turntable 410, while others are exited through an outlet 218 drilled under the turntable 410.
