[0036] Please refer to Figures 1 to 4The embodiment provides a UV curing box, which comprises a box body 1, a carrier table 2, a driving member 3 and a plurality of UV lamps 4. The box body 1 has a working cavity 11 inside, and a box door 12 is hinged to the box body 1 to close the working cavity 11. The carrier table 2 is rotationally arranged in the working cavity 11 and is used for carrying products. The driving member 3 is arranged in the working cavity 11 and is configured to drive the carrier table 2 to rotate. The plurality of UV lamps 4 are arranged on the inner side walls of the working cavity 11 and are located around the carrier table 2 to irradiate the products on the carrier table 2.

[0037] In the embodiment, the driving member 3 is composed of a rotating motor and a stepless speed regulator to control the rotating speed of the carrier table 2, and the rotating speed can be adjusted in the range of 1r-10r / min. In this way, the rotating speed of the carrier table 2 can be adjusted according to different products, and the applicability is high. The basic structure of the rotating motor is composed of a stator, a rotor and an air gap. The stator is fixed, and the rotor is movable, and they are separated by a thin air gap. A plurality of coils are arranged on the stator and the rotor as required, and the purpose is to generate a magnetic field in the air gap. The rotating motor is an electromechanical energy conversion device, which can convert electrical energy into mechanical energy, and also can convert mechanical energy into electrical energy. Since the mechanical system and the electrical system are two different systems, the energy conversion must have an intermediate medium, and this task is completed by the coupling magnetic field composed of the air gap. In other feasible embodiments, the driving member 3 can select any rotating driving structure in the prior art, and the embodiment does not make any requirement and limitation on this.

[0038] During curing, the box door 12 is opened first, then the products are placed on the carrier table 2, then the box door 12 is closed, the UV lamps 4 are turned on, the driving member 3 is started, the carrier table 2 rotates to drive the products to rotate, and meanwhile, the UV lamps 4 continuously irradiate the products. In this way, the products are driven to rotate together by the carrier table 2, so that the ultraviolet rays emitted by the UV lamps 4 can irradiate the circumferential side of the products uniformly, that is, the products can be uniformly irradiated, and then the curing speed and the curing quality are improved. In addition, the products on the carrier table 2 are irradiated by the plurality of UV lamps 4 arranged around the carrier table 2, and the curing speed is further improved.

[0039] In the embodiment, the UV lamps 4 are six. Further, the UV lamps 4 are preferably UVLED lamps, and the specific structure of the UVLED lamp is mainly composed of InGaN quantum wells clamped in a thin GaN sandwich structure. By changing the relative proportion of InN-GaN in the InGaN quantum well, the emission wavelength can be adjusted to cover different ultraviolet light bands. The light source wavelength can be selected, such as 365nm, 395nm and the like, which will not be described in detail.

[0040] To further improve the curing speed, the inner side wall of the working cavity 11 is provided with a reflecting surface 5, which is configured to reflect the ultraviolet light emitted by the ultraviolet lamp 4. In this way, the light emitted by the ultraviolet lamp 4 can be refracted to the product through the reflecting surface 5, thereby helping to improve the light intensity on the product.

[0041] To further improve the light intensity on the product and reduce light loss, the inner side wall of the working cavity 11 is provided with a reflecting surface 5. In this way, the light emitted by the ultraviolet lamp 4 can be refracted multiple times in the working cavity 11, thereby improving the light intensity on the product. In this embodiment, the inner side wall of the working cavity 11 is made of mirror stainless steel material to form the reflecting surface 5. It can be understood that the reflecting surface 5 made of stainless steel material has simple structure and low production cost. The specific material of the mirror stainless steel includes stainless steel, nickel and molybdenum alloy. The mirror stainless steel is made by special polishing treatment, and when the surface quality reaches "8K" level, it is as bright as a mirror.

[0042] Generally, a large amount of heat and waste gas will be generated during the curing process. If the working cavity 11 is not cooled and the waste gas is not discharged in time, it is easy to cause the ultraviolet curing box to fail. Therefore, the ultraviolet curing box also includes a ventilation mechanism 6, which is configured to discharge the heat and waste gas in the working cavity 11.

[0043] Specifically, the ventilation mechanism 6 includes a casing, an impeller and a rotor motor. The casing is embedded in the air exchange opening of the box body 1, and is usually made of galvanized steel plate or high-quality cold-rolled plate, which has smooth lines, heat resistance, moisture resistance and long service life. The impeller is rotatably arranged in the casing, and is formed by riveting the front disc, the middle disc and the front multi-wing arc type blade. After strict dynamic and static balance correction, the impeller ensures stable operation, high efficiency and low noise. The rotor motor is arranged in the casing and is in transmission connection with the impeller to drive the impeller to rotate, so as to exchange air between the inside and outside of the working cavity 11 and discharge the heat in the working cavity 11. The rotor motor usually adopts an outer rotor design, which makes the fan have small vibration and low noise during operation, and is suitable for use in environments with high noise requirements. It should be noted that the fan is preferably an air conditioning type fan, and the working principle of the air conditioning type fan is based on the principle of the centrifugal fan. When the high-temperature and high-pressure refrigerant vapor from the compressor passes through the condenser, the heat is transferred to the outside air by the condensing fan, so that it is condensed into a liquid. Then, the liquid vaporizes by passing through the expansion valve into the evaporator, absorbing the heat in the air outside the pipe, thereby achieving the refrigeration effect. Of course, in other embodiments, a high-precision temperature control instrument can also be provided, which sets multiple temperature and time controls and supports a cycle control mode. The temperature control output power is calculated by a microcomputer to ensure high precision and high efficiency.

[0044] It is worth noting that if the curing work is carried out in an environment with low temperature, the glue is prone to slow curing speed due to the inability to heat in time. In order to avoid this problem, the inner side wall of the working cavity 11 is filled with heat preservation material to heat preservation of the working cavity 11. It should be noted that the heat preservation material can be selected from expanded polystyrene foam board, extruded polystyrene foam board, rigid polyurethane foam, phenolic resin foam, and preferably rigid polyurethane foam plastic used in refrigerator equipment.

[0045] In order to facilitate the staff to control the curing process, the box door 12 is provided with an observation window 121, so that the staff can monitor the curing process of the working cavity 11 through the observation window 121. Excessive ultraviolet radiation can cause damage to the eyes, skin and other parts of the staff. Therefore, the observation window 121 is covered with a light shielding film, which is configured to filter ultraviolet rays. It should be noted that the main materials of the light shielding film include polyester, polyethylene film, PVC film and polytetrafluoroethylene film. Polyester is a common light shielding material that can have light shielding effect after treatment. Polyethylene film has the characteristics of light weight, good light transmission, weather resistance and corrosion resistance. The PVC film has high tensile strength and waterproof performance, and is suitable for various climate conditions. The polytetrafluoroethylene film has excellent high temperature resistance and self-cleaning properties, and is suitable for use in high temperature environment.

[0046] In this embodiment, the box body 1 is provided with a partition plate 13, which divides the inner cavity of the box body 1 into a working cavity 11 and a storage cavity (not marked in the figure). The storage cavity stores the products treated by the working cavity 11. In this way, the storage cavity can be used to store the products treated by the working cavity 11, which is more convenient for taking, placing and storing. In particular, the working cavity 11 and the storage cavity are arranged above and below, and the working cavity 11 is located above the storage cavity. The two cavities are independently arranged, which not only facilitates taking, placing and storing, but also effectively reduces the heat conduction from the working cavity 11 to the products in the storage cavity, thereby making the storage safer.

[0047] In this embodiment, the box body 1 is further provided with a roller at the bottom, which can facilitate the movement of the box body, greatly facilitating the demand for use in different occasions.

[0048] The ultraviolet curing box of the utility model has simple structure, can drive the product to rotate through the loading platform 2, realize different angle irradiation of the product, and has good effect.

[0049] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
