Description

Technical Field

[0001] This utility model belongs to the field of UV adhesive curing technology equipment, and specifically relates to a UV adhesive curing light source device. Background Technology

[0002] UV adhesive curing is an environmentally friendly technology that uses ultraviolet light to initiate a polymerization reaction, rapidly curing UV adhesives within seconds. It is widely used in electronics, medical, and optics fields. The curing principle involves a photoinitiator absorbing ultraviolet light to generate active free radicals or cations, causing the liquid adhesive to transform into a solid state within seconds to tens of seconds. In the manufacture of medical devices, UV adhesives provide a high-strength and rapid curing solution. UV adhesives require a suitable UV curing light source; however, current UV adhesive curing light sources suffer from long curing times and uneven heating. Since medical device processing demands high curing uniformity, improvements to existing technologies are necessary to overcome these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a UV adhesive curing light source device that can improve the uniformity of UV adhesive curing irradiation, improve the uniformity of heating, thereby shortening the curing time and improving the precision of the curing process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A UV adhesive curing light source device includes a base, curing LED beads, an end plate, and a cover plate. A circuit board is disposed on the base, and the base has a rectangular frame structure so that a light outlet is formed in the middle of the base. The curing LED beads are connected to the circuit board, and the curing LED beads are arranged horizontally with their direction upward and spaced along the edge of the circuit board. The end plate is vertically disposed along the outer side of the base, and the cover plate covers the upper end of the end plate. The inner side of the end plate and the bottom side of the cover plate are respectively coated with diffuse reflection paint.

[0005] As a preferred embodiment of the above-mentioned UV adhesive curing light source device, the inner edge of the base is formed with a reflective slope extending inward, and the slope of the reflective slope faces upward.

[0006] As a preferred embodiment of the aforementioned UV adhesive curing light source device, the reflective inclined surface is coated with diffuse reflective paint.

[0007] As a preferred embodiment of the aforementioned UV adhesive curing light source device, the cover plate is provided with a detection hole.

[0008] As a preferred embodiment of the above-mentioned UV adhesive curing light source device, a power connector is provided on the end plate, and the power connector is electrically connected to the curing light bulb through the circuit board.

[0009] As a preferred embodiment of the aforementioned UV adhesive curing light source device, the end plate is provided with an outlet plate for accommodating wires.

[0010] As a preferred embodiment of the aforementioned UV adhesive curing light source device, the curing light beads are made of quartz glass.

[0011] As a preferred embodiment of the aforementioned UV adhesive curing light source device, the UV adhesive curing light source device is also connected to a monitoring and remote control system, which can monitor and adjust the luminescence of the curing light beads in real time.

[0012] The advantages of implementing the UV adhesive curing light source device provided by this utility model compared with the prior art are as follows: In this invention, the end plate and cover plate together form a shell structure that covers the curing LED bead. The inner side of the end plate and the bottom side of the cover plate are coated with diffuse reflection paint. With the curing LED bead facing upwards, the curing light shines upwards and, upon hitting the inner side of the end plate and the bottom side of the cover plate, undergoes diffuse reflection. After continuous emission within the shell structure formed by the end plate and cover plate, the curing light finally shines downwards from the light outlet on the base. The curing light shining downwards from the light outlet has undergone multiple diffuse reflections within the shell structure formed by the end plate and cover plate, resulting in high uniformity of the curing light output and avoiding [further issues]. Direct irradiation of the curing light beads can cause uneven light emission. After multiple diffuse reflections, the light is emitted downwards, resulting in a more uniform heating effect and shortening the curing time. Moreover, the highly uniform curing light provides better curing effect for UV adhesives, resulting in higher precision in the curing process and meeting the processing requirements of medical equipment. The curing light beads are laid out at intervals along the edge of the circuit board. The spacing between multiple beads also makes the light emission after diffuse reflection more uniform. The rectangular frame structure of the base forms a light outlet in the middle of the base, which facilitates the upward irradiation of the curing light beads and the downward emission after diffuse reflection, making the light emission more uniform.

[0020] Please refer to the following: Figures 1 to 4 The UV adhesive curing light source device provided in the embodiments of this utility model will now be described.

[0021] like Figures 1 to 4As shown, the UV adhesive curing light source device of this utility model includes a base 100, curing light beads 300, an end plate 400, and a cover plate 500. A circuit board 200 is provided on the base 100. The base 100 has a rectangular frame structure, forming a light outlet 120 in the middle of the base 100. The curing light beads 300 are connected to the circuit board 200. The curing light beads 300 face upward and are laid flat at intervals along the edge of the circuit board 200. The end plate 400 is vertically arranged along the outer side of the base 100. The cover plate 500 covers the upper end of the end plate 400. The inner side of the end plate 400 and the bottom side of the cover plate 500 are respectively sprayed with diffuse reflection paint.

[0022] Specifically, the curing LED bead 300 faces upwards, meaning the light emitted by the curing LED bead 300 will be projected upwards and to the upper side. The emitted light will first illuminate the inner side of the end plate 400 or the bottom side of the cover plate 500. Both the inner side of the end plate 400 and the bottom side of the cover plate 500 are coated with diffuse-reflecting paint, causing the light emitted by the curing LED bead 300 to undergo continuous diffuse reflection within the housing structure formed by the end plate 400 and the cover plate 500, until the diffusely reflected cured light forms a light outlet 120 in the center of the base 100 and shines downwards. The light emitted from the light outlet 120 undergoes diffuse reflection, resulting in high uniformity of the emitted curing light. This avoids the uneven curing caused by the curing light beads 300 directly irradiating the UV adhesive. By arranging the curing light beads 300 at intervals along the edge of the circuit board 200, and by having the end plate 400 and the cover plate 500 together form a shell structure, the light emitted by the curing light beads 300 shines upwards, undergoes diffuse reflection, and then shines downwards to produce uniform curing light. This improves the uniformity of UV adhesive curing and meets the curing processing requirements of medical equipment.

[0023] Diffuse reflection paint is a type of diffuse reflection coating material composed of base material, diffuse reflection material, high thermal conductivity material, filler, etc. It is formed by spraying to form a film so that light shines on the surface of the object and causes diffuse reflection. Diffuse reflection paint is an existing technology and will not be described in detail here.

[0024] like Figure 3 , 4 As shown, a reflective inclined surface 110 extending inward is formed on the inner edge of the base 100, with the inclined surface of the reflective inclined surface 110 facing upward. The reflective inclined surface 110 extends inward towards the base 100 and faces downward, allowing the curing light irradiated by the inclined surface to be reflected upward for further diffuse reflection. This avoids some of the light emitted by the curing lamp beads 300 being diffusely reflected only by the bottom side of the cover plate 500 and then directly emitted downward from the light outlet 120, thus making the diffuse reflection process of the curing light longer and improving uniformity.

[0025] For example, the reflective slope 110 is sprayed with diffuse reflective paint, so that the curing light reflected to the reflective slope 110 continues to undergo diffuse reflection, prolonging the diffuse reflection process and making the curing light more uniform.

[0026] like Figures 1-4 As shown, a detection hole 510 is provided on the cover plate 500. The detection hole 510 is used to place a camera or detection equipment to detect the curing light emitted from the detection hole 510 after diffuse reflection, thereby detecting the curing light after diffuse reflection, and detecting the uniformity and light intensity of the curing light after diffuse reflection.

[0027] like Figure 1 , 2 As shown, a power connector 410 is provided on the end plate 400. The power connector 410 is electrically connected to the curing LED bead 300 through the circuit board 200. The power connector 410 is connected to a power source, which supplies power to the circuit board 200 and the curing LED bead 300 through the power connector 410. By connecting the power connector 410 to the power source and placing the power connector 410 on the outside of the end plate 400, the power connector 410 is prevented from being heated within the housing structure formed by the end plate 400 and the cover plate 500, thus improving safety during use.

[0028] like Figure 1 , 2 As shown, the end plate 400 is provided with a cable outlet plate 420 for accommodating the wires. The cable outlet plate 420 is located on the outside of the end plate 400 and is used to accommodate the wires, preventing the wires from entering the housing structure formed by the end plate 400 and the cover plate 500 and getting heated, which would affect the power supply safety.

[0029] For example, the curing LED chip 300 is made of quartz glass. Quartz glass chips have a long lifespan, avoiding the need for frequent replacements.

[0030] For example, the UV adhesive curing light source device is also connected to a monitoring and remote control system, which can monitor and adjust the luminescence of the curing light bulb 300 in real time. By remotely monitoring and adjusting the light intensity and other conditions of the curing light bulb 300, the device can adapt to UV adhesive curing under different conditions, thus enabling it to meet the processing needs of different equipment.

[0031] The advantages of implementing the UV adhesive curing light source device provided by this utility model compared with the prior art are as follows: In this invention, the end plate 400 and the cover plate 500 together form a shell structure covering the curing lamp bead 300. The inner side of the end plate 400 and the bottom side of the cover plate 500 are respectively coated with diffuse reflection paint. With the curing lamp bead 300 facing upwards, the curing light shines upwards. When it hits the inner side of the end plate 400 and the bottom side of the cover plate 500, diffuse reflection occurs. After continuous emission within the shell structure formed by the end plate 400 and the cover plate 500, the curing light finally shines downwards from the light outlet 120 on the base 100. The curing light shining downwards from the light outlet 120 is curing light that has undergone multiple diffuse reflections within the shell structure formed by the end plate 400 and the cover plate 500, thus... The curing light emits light with high uniformity, avoiding the uneven light emission caused by direct irradiation of the curing light beads 300. After multiple diffuse reflections, the light is emitted downwards, resulting in uniform heating and shortening the curing time. Moreover, the highly uniform curing light has a good curing effect on UV adhesives, resulting in higher precision in the curing process and meeting the processing requirements of medical equipment. The curing light beads 300 are laid out at intervals along the edge of the circuit board 200. The spaced arrangement of multiple beads also makes the light emission after diffuse reflection more uniform. The rectangular frame structure of the base 100 forms a light outlet 120 in the middle of the base 100, which facilitates the upward irradiation of the curing light beads and the downward emission after diffuse reflection, making the light emission more uniform.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
