Description

Technical Field

[0001] The utility model relates to the technical field of curing boxes, in particular to a xenon lamp curing box structure. Background Art

[0002] Photocuring technology, as a technology that uses ultraviolet (UV) or visible light radiation to cause substances to undergo chemical reactions and solidify, has demonstrated its unique advantages in many fields such as electronics manufacturing, automobile manufacturing, medical devices, household items, and 3D printing.

[0003] Currently, UV LED light sources have become the mainstream application of photocuring technology. With their long life, low energy consumption, fast startup, and mercury-free environmental protection, UV LED light sources have excellent curing efficiency and environmental friendliness. UV LED light sources can emit ultraviolet light of a specific wavelength with high energy density and monochromaticity. These ultraviolet rays can quickly excite the photosensitizer in the material, triggering a cross-linking reaction, thereby achieving rapid curing of the material.

[0004] A representative example is the patent document with application number CN201721663443.4, which discloses an underwater light curing system. The patent document includes: a box body and a light curing machine inner box built into the box body; the light curing machine inner box includes a reflector box and a transparent water tank built into the reflector box; at least one ultraviolet light assembly is provided on the reflector box, and the ultraviolet light assembly is facing the transparent water tank to generate flashing light.

[0005] In the above technical solution, the ultraviolet light assembly on the reflective mirror box flashes to illuminate the product to be cured in the transparent water tank, thereby improving the curing effect while avoiding embrittlement of the product caused by continuous exposure; in addition, the transparent water tank is used to place a curing medium such as pure water. The product to be cured is placed in the water, which can be isolated from most of the oxygen, thereby improving the curing effect.

[0006] However, the technical solutions disclosed in the above patent documents still have limitations in actual use because:

[0007] First, the narrow spectrum distribution of UV LED affects the curing speed: UVLED light sources are mainly concentrated in a narrow range of the ultraviolet spectrum, such as wavelengths of 365nm, 385nm, 395nm and 405nm, but in some applications, if the photoinitiator and UVLED light source are not well matched, the curing rate may be reduced.

[0008] Secondly, the problem of light intensity attenuation: Although UVLED light sources have high light intensity at specific wavelengths, their light intensity will decay with the increase of usage time and frequency, making it difficult to achieve sufficiently high irradiation energy, which can easily lead to low curing rate or incomplete curing of photosensitive materials.

[0009] Again, the issue of curing depth: Due to the spectral characteristics (narrow spectral range) and power limitations (insufficient light intensity), UVLED light sources may have difficulty achieving a deeper curing depth in some applications.

[0010] Finally, although the above patent document uses a solidification medium such as pure water to isolate the solidification medium from most oxygen, the use of pure water as a solidification medium still has some shortcomings. Specifically, first, when the pure water is placed in the transparent water tank, some oxygen will dissolve in it, causing the solidified object to slowly come into contact with oxygen;

[0011] Second, the use of pure water is very limited, that is, it can only be used for objects that are insoluble in water, and the injection and discharge of pure water is relatively cumbersome. Not only do you need to worry about water splashing during injection and the amount of injection, but you also need to worry about the problem of water not being drained cleanly during discharge.

[0012] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Utility Model Content

[0013] The utility model provides a xenon lamp curing box structure, aiming to solve the technical problems raised in the above background technology.

[0020] The xenon lamp curing box structure further includes a control circuit, which is electrically connected to the xenon lamp illuminator and the air guide pipe to control the number of flashes of the xenon lamp illuminator and the switch of the air guide pipe.

[0021] In the above technical solution, the gas injected by the gas injection unit can be nitrogen, helium or other protective gases that can effectively isolate oxygen.

[0022] In the above technical solution, the number of xenon lamp tubes can be one or more, which is convenient for users to set according to actual needs.

[0023] In the above solution, an operation panel can be installed on the outside of the chassis. Inside the operation panel is a main control circuit board (i.e., the control circuit described in the above solution). The operation panel includes a mode selection key and a strobe frequency selection key. The main control circuit board controls the xenon lamp driver (i.e., the device that drives the xenon lamp's light source on and off) and the protective gas valve. The operating mode is selected using the mode selection key, and the strobe frequency selection key adjusts the xenon lamp's strobe frequency. This allows for a targeted curing process based on actual application requirements.

[0024] The working principle of the xenon lamp tube is that a high-voltage coil is wrapped around the outer periphery of the xenon lamp light source, and a high-voltage package is provided on the chassis circuit board to boost the voltage of the high-voltage coil.

[0026] The operation panel can adopt mechanical buttons, touch buttons, touch screen or a combination of the above solutions.

[0029] Furthermore, mounting holes are provided at positions corresponding to the second cover body and the curing inner box. The closing cover is located between the second cover body and the first cover body and is positioned and connected in the mounting holes.

[0031] According to a further technical solution, the closing cover includes a closing plate and a covering plate;

[0032] The closing plate is arranged in the mounting hole and is positioned and connected to the opening of the curing inner box. The covering plate is arranged above the closing plate and is positioned and connected to the second cover body.

The two pairs of vertical plates are connected end to end in sequence and combined to form an annular structure. One pair of the vertical plates is symmetrically arranged on the closing plate, and the other pair of the vertical plates is symmetrically arranged on the covering plate.

[0034] The vent is arranged on the surface of the closing plate, and an air injection port is arranged on the surface of one of the two pairs of vertical plates.

[0035] With the help of the above design, the air guide pipe can be installed in the vent through the guidance of the closed chamber. Under normal circumstances, the path between the vent and the gas injection port is L-shaped. If there is no closed chamber, it is more difficult to install the air guide pipe.

[0036] According to a further technical solution, the chassis body is a structure with a closed top, and a placement opening is provided on the closed top of the chassis body. The curing inner box cooperates with the placement opening to achieve a plug-in connection with the chassis body and the top of the chassis body.

[0037] A closed ring plate is provided along the opening edge of the curing inner box, and the closed ring plate is positioned and connected to the lower surface of the closed plate.

[0038] The function of the closed ring plate is to further seal the opening of the curing inner box and the lower surface of the closed plate.

[0039] According to a further technical solution, both ends of the xenon lamp illuminator are fixed with a frame fixedly connected to the chassis body;

[0040] The xenon lamp illuminator is located at the bottom and / or the peripheral side of the curing inner box.

[0041] The xenon lamp illuminator can be arranged directly below the bottom of the curing inner box, or on the peripheral side of the curing inner box, or even simultaneously on the bottom directly below and the peripheral side of the curing inner box.

[0042] According to a further technical solution, the air guide line includes an air inlet pipe, a valve and an air outlet tube;

[0043] The air inlet pipe is provided through the bottom side wall of the chassis body, the valve is provided at the bottom of the chassis body, and the outlet tube is provided through the top of the chassis body;

[0044] The air inlet pipe, the valve, the outlet tube, the air injection port and the air vent are connected through a pipeline.

[0045] According to a further technical solution, the xenon lamp curing box structure further includes a protective net, which is positioned and connected inside the box body and is located between the xenon lamp light source and the curing inner box.

[0046] According to a further technical solution, the xenon lamp curing box structure further includes an isolation plate, which is positioned and connected inside the chassis body. The isolation plate is used to cover the curing inner box and the xenon lamp tube to isolate the air duct and the xenon lamp tube.

[0047] According to a further technical solution, two opposite side surfaces of the chassis body are respectively provided with a heat fan and a ventilation net to form a heat dissipation duct inside the chassis body.

[0048] In a further technical solution, a high-voltage coil is wound around the outside of the xenon lamp light-emitting body;

[0049] A timer is provided inside the chassis body for recording the working time of the xenon lamp illuminator.

[0050] Regarding the solution of wrapping a high-voltage coil around the xenon lamp: A high-voltage coil is wrapped around the outer periphery of the xenon lamp tube. A high-voltage package is installed on the circuit board of the chassis to boost the voltage of the high-voltage coil. The high-voltage coil can generate a high-voltage arc of tens of thousands of volts, which excites the xenon gas in the xenon lamp tube to produce a sufficiently high light intensity.

[0051] Regarding the timer solution: a timer is provided to record the usage time of the xenon lamp, so as to intuitively know whether the xenon lamp has reached the end of its service life.

[0053] As used herein, “connected” or “positioned” may refer to two or more components or devices being in direct or indirect physical contact with each other, or may refer to two or more components or devices operating or moving with each other.

[0055] Unless otherwise noted, the terms used herein generally have their ordinary meanings in the art, in the context of this application, and in the specific context. Certain terms used to describe this application are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art regarding the description of this application.

[0056] The terms "front", "back", "up", "down", "left", "right", etc. used in this article are all directional terms. In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0057] The working principle and advantages of this utility model are as follows:

[0058] The present invention can obtain a higher and more stable light intensity than that of ultraviolet light emitting diodes through the cooperation of xenon lamps and gas injection units. At the same time, the gas injection unit can inject protective gas into the chassis body. Compared with pure water, firstly, the oxygen exhaust efficiency is high. After entering the curing inner box, the purpose of exhausting oxygen can be achieved quickly. Secondly, continuous gas filling can ensure that external oxygen is isolated with higher efficiency. Compared with pure water, there will be no oxygen mixing. Finally, compared with pure water, the gas injection method of the gas injection unit has a wider range of applications, and there is no need to worry about splashing during injection, and it is directly discharged into the air during discharge without worrying about residue.

[0059] Specifically, the object is directly placed in the curing inner box, and then external protective gas is introduced through the gas duct, and the protective gas is filled into the curing inner box through the closed chamber to isolate the object from oxygen and prevent oxygen inhibition during the curing process. After that, the xenon lamp light source is turned on. At this time, the xenon lamp light source will serve as the curing action part for curing the object in the curing inner box.

[0060] A coil is provided outside the xenon lamp light-emitting body, which can enhance the power of the xenon lamp light-emitting body.

[0061] During the curing process, the xenon lamp's stroboscopic frequency can be controlled by the control circuit to solve the problems of narrow spectral range, low light intensity and single functional mode. Finally, after the curing operation is completed, the problem of the medium used to isolate oxygen being difficult to clean is solved by exhausting the protective gas into the air.

[0062] Compared to UV LEDs (ultraviolet light-emitting diodes), xenon lamps have a wider spectral distribution and can better match photoinitiators in various applications.

[0063] Compared with UV LEDs, xenon lamps can achieve higher power, provide higher and more stable light intensity, and improve curing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0078] Embodiment: The present invention will be clearly illustrated below with drawings and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0079] The terms used herein are for describing specific embodiments only and are not intended to be limiting of the present invention. Singular forms such as "a," "the," "this," "this," and "the" as used herein also include plural forms.

[0080] See attached Figures 1-12 As shown, a xenon light curing box structure includes a chassis body 1, a box cover 15 positioned and connected to the chassis body 1, a curing inner box 2, a xenon lamp tube 3 and a gas injection unit 4;

[0081] The curing inner box 2 and the xenon lamp tube 3 are arranged in order from top to bottom in the chassis body 1;

[0082] The xenon lamp tube 3 includes a xenon lamp illuminator 6 and a frame 5. The xenon lamp illuminator 6 is positioned and connected to the chassis body 1 through the frame 5, and the xenon lamp illuminator 6 is arranged outside the curing inner box 2. The xenon lamp illuminator 6 serves as a curing action part for curing the object in the curing inner box 2.

[0083] The gas injection unit 4 includes a gas guide pipe 7 and a closing cover 8. When the box cover 15 is covered on the top of the box body 1, the closing cover 8 is configured to act on the opening of the curing inner box 2 to achieve sealing of the curing inner box 2.

[0084] The closing cover 8 is provided with a vent 9 which is connected to the curing inner box 2;

[0085] The air guide pipe 7 is located inside the chassis body 1. One end of the air guide pipe 7 is used to introduce protective gas, and the other end of the air guide pipe 7 passes through the vent 9 and communicates with the curing inner box 2.

[0086] The xenon lamp curing box structure further includes a control circuit, which is electrically connected to the xenon lamp illuminator 6 and the air duct 7 to control the number of flashes of the xenon lamp illuminator 6 and the switch of the air duct 7.

[0087] The present invention can obtain a higher and more stable light intensity than that of ultraviolet light emitting diodes through the cooperation of the xenon lamp tube 3 and the gas injection unit 4. At the same time, the gas injection unit 4 can inject protective gas into the chassis body 1. Compared with pure water, firstly, the oxygen exhaust efficiency is high. After entering the curing inner box 2, the purpose of exhausting oxygen can be quickly achieved. Secondly, continuous gas filling can ensure that external oxygen is isolated with higher efficiency. Compared with pure water, there will be no oxygen mixing. Finally, compared with pure water, the gas injection method of the gas injection unit 4 has a wider range of applications, and there is no need to worry about splashing during injection, and it is directly discharged into the air during discharge without worrying about residue.

[0088] Specifically, the object is directly placed in the curing inner box 2, and then, external protective gas is introduced through the gas guide pipe 7, and the protective gas is passed into the curing inner box 2 to isolate the object from oxygen and prevent oxygen inhibition during the curing process. After that, the xenon lamp light 6 is turned on. At this time, the xenon lamp light 6 will serve as the curing action part for curing the object in the curing inner box 2.

[0089] During the curing process, the number of flashes of the xenon lamp light emitting element 6 can be controlled by the control circuit to solve the problems of narrow spectral range, low light intensity and single functional mode. Finally, after the curing operation is completed, the problem of the medium used to isolate oxygen being difficult to clean is solved by exhausting the protective gas into the air.

[0090] It should be noted that the gas injected by the gas injection unit 4 can be nitrogen, and the nitrogen filling pressure is 0.1-0.15 MPa.

[0091] Compared to UV LEDs (ultraviolet light-emitting diodes), xenon lamps have a wider spectral distribution and can better match photoinitiators in various applications.

[0092] Compared with UV LEDs, xenon lamps can achieve higher power, provide higher and more stable light intensity, and improve curing efficiency.

[0093] This solution aims at practicality in various applications, provides multiple curing modes for curing the inner box 2 and provides simple and fast operation logic.

[0094] Specifically, the xenon lamp illuminator 6 can be arranged at the bottom of the outer side of the curing inner box 2 or around the outer side of the curing inner box 2 or simultaneously directly below the bottom and around the outer side of the curing inner box 2 .

[0095] The top of the chassis body 1 can be closed or open (when open, the curing inner box 2, the xenon lamp tube 3 and the gas injection unit 4 need to be fixed by means of connecting rods and other devices, so most people choose a closed chassis body 1).

[0096] like Figures 1-12 In some specific embodiments, the box cover 15 includes a first cover body 25 and a second cover body 26. The first cover body 25 is rotatably connected to the top of the chassis body 1, and the second cover body 26 is positioned and connected to the side surface of the first cover body 25 facing the curing inner box 2.

[0097] Mounting holes 27 are provided at positions corresponding to the second cover 26 and the curing inner box 2 . The closing cover 8 is located between the second cover 26 and the first cover 25 and is positioned and connected in the mounting hole 27 .

[0098] With the above design, the closing cover 8 can follow the opening or closing of the box cover 15 to achieve the purpose of sealing or opening the opening of the curing inner box 2.

[0099] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 In some embodiments, the closing cover 8 includes a closing plate 12 and a covering plate 13;

[0100] The closing plate 12 is arranged in the mounting hole 27 and is positioned and connected to the opening of the curing inner box 2. The covering plate 13 is arranged above the closing plate 12 and is positioned and connected to the second cover body 26. Two pairs of vertical plates 14 are arranged between the closing plate 12 and the covering plate 13. The two pairs of vertical plates 14 are connected end to end and combined to form an annular structure. One pair of vertical plates 14 is symmetrically arranged on the closing plate 12, and the other pair of vertical plates 14 is symmetrically arranged on the covering plate 13. The vent 9 is arranged on the surface of the closing plate 12, and the gas injection port 11 is arranged on the surface of one of the two pairs of vertical plates 14.

[0101] A closed chamber 10 is formed between the closing plate 12 , the covering plate 13 and the two pairs of vertical plates 14 for accommodating and guiding the air guide pipe 7 to pass through the vent 9 .

[0102] With the help of the above design, the air guide pipe 7 can be installed in the vent 9 through the guidance of the closed chamber 10. Under normal circumstances, the path between the vent 9 and the gas injection port 11 is L-shaped. If there is no closed chamber, it will be difficult to install the air guide pipe 7.

[0103] In some specific embodiments, the air guide line 7 includes an air inlet pipe 19, a valve 20, and a guide tube 21;

[0104] Among them, the air inlet pipe 19 is provided on the bottom side wall of the chassis body 1, the valve 20 is provided on the bottom of the chassis body 1, and the outlet tube 21 is provided on the top of the chassis body 1;

[0105] The air inlet pipe 19, the valve 20, the outlet tube 21, the air injection port 11 and the air vent 9 are connected through a pipeline.

[0106] The pipeline can be a soft tube or a hard tube, and the number is not limited. It can be one pipeline connecting all the structures in the above-mentioned air guide pipeline 7, or multiple pipelines can be set between adjacent structures in the above-mentioned air guide pipeline 7.

[0107] It should be noted that: Figures 1-12 The middle pipe is not drawn.

[0108] The closing plate 12 and the covering plate 13 may be connected by screws, latches or welding.

[0109] The closing cover 8 can be made of a solid plate structure, but this will make the closing chamber 10 equivalent to a groove formed on the solid plate structure, making it difficult to insert the air duct 7 therein.

[0110] It can also be set as a plate with only one vent 9 provided on it, and the air guide pipe 7 is directly inserted into the vent 9 to inject gas into the curing inner box 2. However, this operation is prone to occur when the gas pressure is high, causing the end of the air guide pipe 7 inserted into the vent 9 to be pushed out of the vent 9.

[0111] The above design not only facilitates the insertion of the air guide pipe 7 , but also prevents the end of the air guide pipe 7 inserted into the vent 9 from being pushed out of the vent 9 when the air guide pipe 7 is injected with air.

[0112] When installing the air guide pipe 7, the air inlet pipe 19 is connected to the air inlet of the valve 20 through a pipe, and then a pipe is connected to the air outlet of the valve 20. The pipe is then guided to pass through the guide tube 21, and then the pipe is guided to pass through the air injection port 11. The specific position of the air injection port 11 is not fixed, but it can be preferably set on the surface of the vertical plate 14 on the closing plate 12, so that after the pipe passes through the air injection port 11, it can quickly pass through the air vent 9, and then the covering plate 13 is covered on the closing plate 12 and fixedly connected by screws or the like.

[0113] It should be noted that after the pipeline is installed, the covering plate 13 is no longer separated from the closing plate 12, that is, the pipeline is always installed in the vent 9.

[0114] During the curing operation, the object is placed in the curing inner box 2, and then the box cover 15 is closed.

[0115] Since the closing cover 8 can move along with the box cover 15, the opening of the curing inner box 2 can be sealed or opened by opening or closing the box cover 15. When the closing plate 12 is pressed against the opening of the curing inner box 2, the opening edge of the curing inner box 2 can be sealed.

[0116] Since a closed ring plate 24 is provided along the opening edge of the curing inner box 2 , the closed ring plate 24 is positioned and connected to the lower surface of the closing plate 12 .

[0117] like Figure 11 Therefore, the opening edge of the curing inner box 2 is more sealed at this time.

[0118] The opening of the curing inner box 2 and the closing plate 12 can be matched, that is, one is a quadrilateral or a circle and the other is also a quadrilateral or a circle, but they do not have to be matched. The basic requirement is that the closing plate 12 is pressed on the opening of the curing inner box 2 without producing a large gap.

[0119] Subsequently, the pipe at the gas outlet of the valve 20 guides the protective gas into the curing inner box 2 to discharge the oxygen in the curing inner box 2, so that oxygen inhibition will not occur during the subsequent light curing operation.

[0120] like Figures 1-12 In some specific embodiments, the chassis body 1 is a closed top structure, and the closed top of the chassis body 1 is provided with a placement opening 16. The curing inner box 2 cooperates with the placement opening 16 to achieve a plug-in connection with the top of the chassis body 1.

[0121] In some specific embodiments, a frame 5 fixed to the chassis body 1 is fixed at both ends of the xenon lamp illuminator 6;

[0122] The xenon lamp illuminator 6 is located at the bottom and / or the peripheral side of the curing inner box 2 .

[0123] Preferably, the xenon lamp illuminator 6 is located directly below the bottom of the curing inner box 2;

[0124] The xenon lamp tubes 3 are provided in plurality and arranged in an array.

[0125] This design allows the xenon lamp 6 to fully cure the object from bottom to top (the light emitted by the xenon lamp 6 is penetrating, thus fully ensuring the curing effect). Furthermore, due to the structural design of the xenon lamp 6 itself, this bottom-up arrangement leaves sufficient installation space for the xenon lamp 6.

[0126] like Figure 2 and Figure 5 As shown, in some embodiments, the xenon lamp curing box structure further includes a protective net 17, which is positioned and connected to the chassis body 1 and located between the xenon lamp illuminator 6 and the curing inner box 2. The protective net 17 is located between the xenon lamp illuminator 6 and the curing inner box 2, and this design can prevent debris from falling onto the xenon lamp illuminator 6.

[0127] like Figure 3 and Figure 4 As shown, in some specific embodiments, the xenon lamp curing box structure also includes an isolation plate 18, which is positioned and connected inside the chassis body 1. The isolation plate 18 is used to cover the curing inner box 2 and the xenon lamp tube 3 to isolate the air duct 7 and the xenon lamp tube 3.

[0128] This design prevents the xenon lamp illuminator 6 from affecting the normal operation of the gas conduit 7 or other components, for example, a high-voltage arc may damage a component.

[0129] In some embodiments, a heat fan 22 and a ventilation net 23 are provided on two opposite sides of the chassis body 1, respectively, to form a heat dissipation duct inside the chassis body 1. This design allows heat generated by operating components inside the chassis body 1 and dust entering from the outside to be removed from the outside.

[0130] In some specific embodiments, a high voltage coil is wound around the xenon lamp illuminator 6;

[0131] A timer is provided in the chassis body 1 for recording the working time of the xenon lamp illuminator 6 .

[0132] It should be noted that the high voltage coil and timer are not shown.

[0133] Regarding the solution of wrapping a high-voltage coil around the xenon lamp: A high-voltage coil is wrapped around the outer periphery of the xenon lamp tube. A high-voltage package is installed on the circuit board of the chassis to boost the voltage of the high-voltage coil. The high-voltage coil can generate a high-voltage arc of tens of thousands of volts, which excites the xenon gas in the xenon lamp tube to produce a sufficiently high light intensity.

[0134] Regarding the timer solution: a timer is provided to record the usage time of the xenon lamp, so as to intuitively know whether the xenon lamp has reached the end of its service life.

[0135] Working principle:

[0136] During the curing operation, an object is placed in the curing inner box 2 and then the box cover 15 is closed. Since the closure cover 8 can move with the box cover 15, the opening of the curing inner box 2 can be blocked or opened by opening or closing the box cover 15. When the closure plate 12 is pressed against the opening of the curing inner box 2, the opening edge of the curing inner box 2 can be sealed.

[0137] Subsequently, the pipe at the outlet of valve 20 guides the protective gas into the curing inner box 2, discharging the oxygen therein. This prevents oxygen inhibition during the subsequent light-curing operation. During the curing process, the control circuit can control the strobing frequency of the xenon lamp illuminator 6 to address the problems of a narrow spectral range, low light intensity, and a single functional mode. Finally, after the curing operation is completed, the protective gas is exhausted to the air to solve the problem of difficult cleaning of the medium used to isolate oxygen.

[0138] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
