Description

Technical Field

[0001] This invention belongs to the field of product curing technology, and in particular relates to a multi-cavity UV curing processing cooling system and unit. Background Technology

[0002] Existing multi-cavity UV curing equipment cannot achieve uniform or independent temperature control settings for each UV curing unit, resulting in poor temperature control sensitivity. For example, patent 201910250999.8 describes a ring-shaped UV curing device, comprising: a frame, ring-shaped UV curing units mounted on the frame, a circulating cooler, and an electrical control system box; each ring-shaped UV curing unit includes: a support unit, several individual light sources mounted on the support unit, and the individual light sources forming a cylindrical UV curing area; each individual light source includes: a heat sink, an LED light board connected to the heat sink, and the heat sink connected to the circulating cooler via a water pipe. This solution's ring-shaped UV curing unit can provide 360° illumination to the object requiring UV curing, and the cylindrical UV curing area formed by the individual light sources can irradiate all surfaces of the object, effectively avoiding the need for multiple UV curing cycles and improving production efficiency.

[0003] While the above solution improves UV processing efficiency, it cannot achieve uniform temperature control for all individual light sources or allow for independent temperature regulation of each individual light source. From the perspective of curing uniformity, the final cured product quality has defects. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a multi-cavity UV curing processing cooling system and unit that can solve the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] This multi-cavity UV curing processing cooling system includes several independent modular UV curing components. Each modular UV curing component is provided with an air-cooling structure for air-cooling the internal space of the UV lamp box of the modular UV curing component. Several air-cooling structures are connected in parallel to a cooling air supply terminal. Each modular UV curing component is also provided with a fluid medium cooling mechanism for heat exchange cooling of the UV lamp box of the modular UV curing component. Several fluid medium cooling mechanisms are connected in parallel to a circulating cooling terminal.

[0007] In the above-mentioned multi-cavity UV curing processing cooling system, each of the air-cooling structures and the cooling air supply terminal are connected by air ducts, and a pressure detector is provided on the air ducts.

[0008] In the above-mentioned multi-cavity UV curing processing cooling system, each of the fluid medium cooling mechanisms and the circulating cooling terminal are connected by a cold water outlet pipe and a heated water return pipe, respectively, and a water flow detection switch is provided on the cold water outlet pipe or the heated water return pipe.

[0009] In the above-mentioned multi-cavity UV curing cooling system, a cold medium inlet pipe and a heat exchange heating medium outlet pipe are provided on the circulating cooling terminal. A first flow detection valve is provided on the cold medium inlet pipe, and a second flow detection valve is provided on the heat exchange heating medium outlet pipe.

[0010] In the aforementioned multi-cavity UV curing cooling system, the UV lamp box includes several curing lamps distributed in different dimensions, and at least one of the curing lamps is provided with the aforementioned air-cooling structure.

[0011] In the above-described multi-cavity UV curing cooling system, at least one of the curing lamps is located on top of the remaining curing lamps, and the top curing lamp is provided with the air-cooling structure.

[0012] In the aforementioned multi-cavity UV curing cooling system, the air-cooling structure includes several air ducts located on the top of the curing lamp and distributed outwards from top to bottom.

[0013] In the above-mentioned multi-cavity UV curing cooling system, the curing lamp has a polygonal structure, and the air ducts are respectively provided on each side of the bottom of the curing lamp. The air ducts provided on the same side of the bottom of the curing lamp are parallel to each other.

[0014] In the aforementioned multi-cavity UV curing cooling system, the main body with air cavities is installed in the vertical through hole inside the curing lamp at the top. Each side of the bottom of the main body is provided with an air duct, and the air ducts encircle the bottom of the main body to form a ring.

[0015] In the aforementioned multi-cavity UV curing cooling system, the fluid medium cooling mechanism includes a water-cooling passage disposed on the UV lamp box.

[0016] In the aforementioned multi-cavity UV curing processing cooling system, the circulating cooling terminal includes a water distributor, on which several cold water outlet pipes and several parallel heated water return pipes are connected in parallel. One of the cold water outlet pipes is connected to the water-cooling passage inlet of one of the UV lamp boxes, and one of the heated water return pipes is connected to the water-cooling passage return outlet of one of the UV lamp boxes. The water distributor is provided with a cold medium inlet pipe and a heat exchange heated medium outlet pipe.

[0017] This application also provides a multi-cavity UV curing processing unit, which includes the aforementioned multi-cavity UV curing processing cooling system.

[0018] In the above-mentioned multi-cavity UV curing processing unit, the multi-cavity UV curing processing unit also includes a frame, on which a curing component fixing frame is provided, and on which a plurality of mutually independent modular UV curing components are provided.

[0019] In the above-mentioned multi-cavity UV curing processing unit, the circulating cooling terminal and the cold air supply terminal are provided on the top of the curing component fixing frame.

[0020] In the above-mentioned multi-cavity UV curing processing unit, a water leakage protection device is provided on the frame below the curing component fixing frame. The water leakage protection device includes a flow guide plate in the frame and a collection container at the water outlet of the flow guide plate. The collection container is connected to the discharge pipe. A liquid level sensor and a drain valve are installed on the discharge pipe. The liquid level sensor is used to detect the water level stored in the discharge pipe after the drain valve is closed.

[0021] Compared with existing technologies, the advantages of this application are:

[0022] By using a parallel approach to independently control the temperature of each modular UV curing component, the temperature uniformity of each modular UV curing component can be ensured, thus achieving consistent curing quality for each product.

[0023] The overlapping of the emitted light from multiple light sources creates a high overlap rate, which can compensate for the fact that the curing lamp cannot achieve ideal working efficiency due to the attenuation of the irradiated light from a single light source, and can effectively improve the effective energy utilization rate of the curing lamp.

[0024] The use of multiple air ducts can cool the inside of the UV lamp box, the fixture inside the UV lamp box, and the workpieces on the fixture. This can significantly improve cooling efficiency, thereby shortening the waiting time for the next workpiece to enter the UV lamp box during sequential processing, and thus greatly improving production efficiency.

[0050] The following are specific embodiments of the invention, which are described in conjunction with the accompanying drawings. The technical solution of the invention will be further described, but the invention is not limited to these embodiments. Example 1

[0051] like Figure 25 As shown, the multi-cavity UV curing processing cooling system of this embodiment includes several independent modular UV curing components A. For example, there are 12 modular UV curing components A, or other numbers. From the perspective of unit utilization, the modular UV curing components A of this embodiment are arranged in an array, i.e., similar to the structure of a grid cabinet.

[0052] like Figure 1 and Figure 8 As shown, the modular UV curing component A includes an installation platform g. Specifically, the installation platform g in this embodiment includes a UV component carrier plate g1. The UV component carrier plate g1 is mounted on a pull-out base plate g2 via a sliding structure. A carrier plate translation driver g3 is provided on the pull-out base plate g2 to drive the UV component carrier plate g1 to translate.

[0053] like Figure 1-2 As shown, the modular UV component mounting structure also includes a travel limiting mechanism. The travel limiting mechanism includes a first fixed limiting member g20 fixed on the pull-out base plate g2 and located at the starting point of the travel of the UV component carrier plate g1, and a second fixed limiting member g21 fixed on the pull-out base plate g2 and located at the ending point of the travel of the UV component carrier plate g1. A second movable limiting member g210 is provided on the UV component carrier plate g1 and is on the same straight line as the second fixed limiting member g21.

[0054] In this embodiment, the carrier plate translation driver g3 is either pneumatically driven or hydraulically driven. Compared with belt drive, its advantages are: a simpler structure, eliminating the need for transmission devices such as belts and gears, thus simplifying the system structure, reducing failures and losses of transmission components, and saving space; higher transmission efficiency, as pneumatic and hydraulic drives directly transfer energy to the actuator, achieving higher transmission efficiency; and greater output torque, as pneumatic and hydraulic drives can control the output torque by adjusting the air or hydraulic pressure. In contrast, belt or gear drives are often limited and cannot flexibly adjust the output torque.

[0055] When the first fixed limiting member g20 contacts the UV component carrier g1, it indicates that the UV component carrier g1 is in the starting or moving reset position.

[0056] When the second movable limiter g210 moves with the UV component carrier g1 and contacts the second fixed limiter g21, it indicates that the UV component carrier g1 has moved to the end position of the stroke, at which point the carrier translation driver g3 stops driving.

[0057] The modular UV component mounting structure also includes two opposing and spaced mounting beams g4, with a pull-out base plate g2 positioned between the two mounting beams g4 and fixed relative to the mounting beams g4 along the length of the mounting beams g4.

[0058] Several walking components g25 are rotatably connected to opposite sides of the pull-out base plate g2. Guide grooves g40 are provided on the opposite inner sides of the two mounting and fixing beams g4. The guide grooves g40 are U-shaped grooves. All the walking components g25 on one side of the pull-out base plate g2 are placed in one guide groove g40, and all the walking components g25 on the other side of the pull-out base plate g2 are placed in the other guide groove g40. When the pull-out base plate g2 is no longer fixed in the length direction, the walking components g25 can move in the guide grooves g40.

[0059] Specifically, when the device restricting the movement of the pull-out base plate g2 is removed, the pull-out base plate g2 can slide along the length of the mounting and fixing beams g4 on both sides using the traveling member g25.

[0060] In this embodiment, the traveling component g25 is a roller or a bearing, which can cooperate with the guide groove g40 to slide relatively smoothly.

[0061] One end of the mounting beam g4 along its length is connected to the corresponding end of the pull-out base plate g2 via a first detachable fixing mechanism; the other end of the mounting beam g4 along its length is connected to the corresponding other end of the pull-out base plate g2 via a second detachable fixing mechanism.

[0062] The first detachable fixing mechanism includes: a fixing positioning block g41 is provided at one end of the mounting fixing beam g4 along the length direction, and the fixing positioning block g41 is fixedly connected to the corresponding end of the pull-out base plate g2 through a first fastener g42.

[0063] In this embodiment, the first fastener g42 is a fastening bolt, which fixes the mounting beam g4 and the pull-out base plate g2 by rotation. It can be other commonly used fasteners.

[0064] The second detachable fixing mechanism includes: a fixing limit block g43 is provided at the other end of the mounting beam g4, which is equipped with a fixing positioning block g41, and the fixing limit block g43 is fixedly connected to the corresponding end of the pull-out base plate g2.

[0065] like Figure 3-4 As shown, a stroke detection component g11 is provided on the UV component carrier plate g1, and a starting point sensor g22 and an ending point sensor g23 are provided on the pull-out base plate g2. The stroke detection component g11 and the starting point sensor g22 work together to detect that the UV component carrier plate g1 is at the starting point, and the stroke detection component g11 and the ending point sensor g23 work together to detect that the UV component carrier plate g1 is at the ending point.

[0066] When the UV module carrier plate g1 starts moving, after running for a period of time, the end point sensor g23 detects that the stroke detection element g11 has reached the detection range, and then controls the UV module carrier plate g1 to stop moving; similarly, when the starting point sensor g22 detects the stroke detection element g11, it means that the UV module carrier plate g1 has returned to the initial position and proceeds to the next process.

[0067] A driver housing space is formed between the UV component carrier plate g1 and the pull-out base plate g2. The carrier plate translation driver g3 is located in the driver housing space. Both ends of the carrier plate translation driver g3 are fixed to the pull-out base plate g2. The drive telescopic rod of the carrier plate translation driver g3 is connected to the UV component carrier plate g1.

[0068] In this embodiment, the carrier plate translation driver g3 is a pen-shaped cylinder, the main body of which is fixed on the pull-out base plate g2. The output rod is fixedly connected to the UV component carrier plate g1. During operation, the output rod drives the UV component carrier plate g1 to move back and forth in the length direction.

[0069] The UV module carrier plate g1 and the pull-out base plate g2 are slidably connected by a guide rail pair g24. The guide rail pair g24 improves the stability of the UV module carrier plate g1's back-and-forth movement and enhances the accuracy of the entire device.

[0070] like Figure 11 and Figure 25As shown, each modular UV curing component A is provided with a cooling structure f for air cooling the internal space of the UV lamp box 2 of the modular UV curing component A. Several cooling structures f are connected in parallel to the cooling air terminal B. In this embodiment, the parallel connection is used to independently control the temperature of each modular UV curing component A, so as to ensure the temperature uniformity of each modular UV curing component A. From the perspective of the curing quality of each product to be cured, the curing quality can be consistent.

[0071] Specifically, in this embodiment, each air-cooled structure f and the cooling air terminal B are connected via air duct f0, and a pressure detector f00 is provided on the air duct f0. The pressure detector f00 is, for example, a pressure sensor or a pressure detection valve, which detects the pressure of each air duct f0 to ensure that the pressure of the cold air delivered by each air duct f0 is consistent, and to ensure the uniformity of temperature control for each modular UV curing component A during cooling. The cooling air terminal B is a multi-channel cooling air supply unit with a structure similar to a water distributor. The cooling air terminal B has a main air inlet, which is connected to an air supply device, for example, a blower, or of course, an air supply fan with cooling plates.

[0072] Furthermore, such as Figures 9-12 As shown, a UV lamp box 2, mounted on a mounting platform g, has a cooling structure f on at least one curing lamp d. The UV lamp box 2 includes several curing lamps d distributed along different dimensions. At least one curing lamp d has an air duct f12 that blows air into the UV lamp box 2. At least one curing lamp d is located on top of the remaining curing lamps d, and the cooling structure is located on the top curing lamp d. Specifically, the cooling structure includes several air ducts f12 located on the top curing lamp d and distributed obliquely from top to bottom. That is, the top curing lamp d has several air ducts f12 distributed obliquely from top to bottom, and the remaining curing lamps d are located below the circumferential side of the top curing lamp d. The dimensions here are described using the XYZ axes. For example, three parallel curing lamps d are distributed around the X-axis. Two of the three curing lamps d distributed around the X-axis are on the same horizontal plane, and the third curing lamp is triangularly distributed with the aforementioned two curing lamps (i.e., the top curing lamp d), with one curing lamp d distributed along the Y-axis.

[0073] The upward flow of heat, coupled with the downward-sloping airflow of the duct f12, forces the heat inside the UV lamp box 2 to dissipate to the surrounding area of ​​the mounting platform g. Due to the inclined design, when the airflow from the duct f12 blows downward, it reaches the curing lamp d at the top and then blows vertically downward. This process also helps dissipate heat from the cured product and the product fixture, shortening the cooling cycle of the cured product. The UV curing assembly in this embodiment also includes a temperature sensor 20 for detecting the temperature inside the UV lamp box 2. The temperature sensor 20 detects the temperature to control whether to initiate the cooling action.

[0074] Secondly, the curing lamp d has a polygonal structure, and each side of the bottom of the curing lamp d is provided with the aforementioned air duct f12. The air ducts f12 located on the same side of the bottom of the curing lamp d are parallel to each other. Specifically, the main body f1 with the air cavity f10 is installed in the vertical through hole inside the top curing lamp d. The air cavity f10 can be understood as a ring-shaped space, or as a space similar to an indoor space.

[0075] like Figures 9-12 As shown, the main body f1 includes a lower shell and an upper shell or upper cover plate that is sealed and fastened to the opening of the lower shell. At this time, the lower shell and the upper shell form a sealed air cavity f10, and the sealing method can be an annular sealing ring.

[0076] Regarding the installation and fixing method of the main body f1, the main body f1 can be fixed to the top of the UV lamp box 2 by the bracket f14. The bracket f14 is similar to an inverted Z-shape. The bracket f14 and the top surface of the UV lamp box 2 are connected by bolt pairs, and the bracket f14 and the top surface of the main body f1 are also connected by bolt pairs.

[0077] Of course, in relation to the above-mentioned fixing method, the UV lamp box 2 in this embodiment is provided with a vertical through hole at the top, and the main body f1 is built into the vertical through hole.

[0078] Secondly, the air cavity f10 is connected to the air supply pipe f11, which in turn is connected to the air supply terminal, such as a blower or other air supply terminal.

[0079] As is well known, UV lamp boxes have UV lamps positioned at different angles on the top and on the lower side of the top for processing workpieces.

[0080] like Figures 9-12 As shown, in order to achieve efficient cooling, such as for the lamp box, workpiece and fixture, this embodiment is implemented by the following scheme: the main body f1 is provided with several air ducts f12 that are connected to the air cavity f10 and blow air downward into the UV lamp box 2.

[0081] By combining the air cavity f10 with several air ducts f12, cooling can be achieved for the inside of the UV lamp box 2, the fixture inside the UV lamp box 2, and the workpieces on the fixture. In terms of cooling efficiency, the cooling efficiency can be greatly improved, thereby shortening the waiting time for the later workpiece to enter the UV lamp box 2 when different workpieces are processed sequentially, thus greatly improving production efficiency.

[0082] Of course, there are multiple ways to set up the air duct f12 in this embodiment. For example, the air duct f12 can be set vertically, or it can be set at an angle. For example, the air duct f12 can be set at an angle of 45°.

[0083] In a preferred embodiment, the air duct f12 is distributed at an angle from top to bottom and outwards. This inclined distribution allows heat to be dissipated at an outward angle.

[0084] In a preferred embodiment, the air ducts f12 are located at the bottom of the main body f1, and the air ducts f12 encircle the bottom of the main body f1 to form a ring. Encircling the bottom can be understood as a circumferentially spaced distribution to improve cooling efficiency and uniformity. In this embodiment, the main body f1 has a polygonal structure, such as a hexagon or octagon. The structure of the main body f1 can be designed according to the shape of the actual workpiece, striving to make the structure of the main body f1 consistent with the polygonal structure of the workpiece to achieve uniform circumferential cooling. Several air ducts f12 are provided on each side of the bottom of the main body f1 to further improve cooling uniformity.

[0085] Secondly, several air ducts f12 located on the same side of the bottom of the main body f1 are parallel to each other. This design can prevent air ducts f12 on different sides from converging in the downward blowing path. That is, the above-mentioned method in this embodiment can ensure that each air duct f12 is not affected by adjacent air ducts f12 during the downward blowing process, thereby improving cooling efficiency.

[0086] Furthermore, in this embodiment, the bottom edge of the main body f1 is provided with an annular inclined surface f13, and the lower air outlet of the air duct f12 is located on the annular inclined surface f13. The design of the annular inclined surface f13 facilitates the drilling and manufacturing of the air duct f12, thereby improving the processing efficiency of the main body f1.

[0087] Secondly, the annular inclined surface f13 is formed by a series of inclined sub-slopes f130 connected sequentially. In the radial direction of the main body f1, the inclination direction of each inclined sub-slope f130 is from top to bottom and inward. Furthermore, the air duct f12 penetrates the bottom of the main body f1, and the lower air outlet of the air duct f12 is located on the inclined sub-slope f130. The several air ducts f12 penetrating from the inclined sub-slope f130 are parallel to each other. That is to say, several air ducts f12 penetrate each inclined sub-slope f130 to improve the cooling efficiency on different sides. These different sides can be understood as different sides of the workpiece, including different sides inside the UV lamp box 2, and also different sides of the workpiece fixture.

[0088] The axis of the air duct f12 is perpendicular to the inclined sub-slope f130 to improve the machining efficiency of the air duct f12.

[0089] Figure 10 The radiating dashed lines in the diagram represent a schematic diagram of air ducts f12 distributed on the same side with parallel air outlets.

[0090] like Figure 25As shown, each modular UV curing component A is also equipped with a fluid medium cooling mechanism d0 for heat exchange and cooling of the UV lamp box 2 of the modular UV curing component A. Several fluid medium cooling mechanisms d0 are connected in parallel to the circulating cooling terminal C. By performing uniform cooling in parallel, the temperature control of all UV lamp boxes 2 can be made uniform, and the curing quality of each product to be cured can be made consistent.

[0091] The combined cooling of each modular UV curing component A by air cooling and a cooling medium can effectively extend the service life of the modular UV curing component A.

[0092] Secondly, each fluid medium cooling mechanism d0 and circulating cooling terminal C are connected through a cold water outlet pipe C01 and a heated water return pipe C02, respectively. A water flow detection switch is installed on the cold water outlet pipe C01 or the heated water return pipe C02. The water flow detection switch d03 detects whether water flows through, whether the water flow rate of different cold water fluid medium pipes is consistent, and whether water flow control is required, so as to form an independent control.

[0093] Furthermore, the fluid medium cooling mechanism d0 of this embodiment includes a water-cooling passage d02 provided on the UV lamp box 2 (that is, the curing lamp d of the UV lamp box 2 is provided with a water-cooling passage d02), and a circulating cooling terminal C includes a water distributor C0. That is, a water-cooling passage d02, a cold water outlet pipe C01, a heated water return pipe C02 and a water distributor C0 form a separate water circulation. Several cold water outlet pipes C01 and several heated water return pipes C02 are connected in parallel on the water distributor C0. The several cold water outlet pipes C01 are arranged in a way that multiple cold water outlet pipes C01 rely on each other, which can mutually balance the temperature of adjacent pipes.

[0094] A cold water outlet pipe C01 is connected to the water inlet of the water-cooled passage d02 of a UV lamp box 2, and a hot water return pipe C02 is connected to the water return outlet of the water-cooled passage d02 of a UV lamp box 2. A cold medium inlet pipe C1 and a heat exchange heating medium outlet pipe C2 are provided on the water distributor C0. The warm water discharged from the heat exchange heating medium outlet pipe C2 can be used in the workshop, for example, for domestic use.

[0095] When a UV lamp box 2 includes several curing lamps d, and each curing lamp d is equipped with a water-cooling passage d02, the outlet of the cold water outlet pipe C01 is equipped with the same number of first multi-way connectors (not shown in the figure) as the number of curing lamps d, and the inlet of the heated water return pipe C02 is also equipped with a second multi-way connector (not shown in the figure). This allows cold water to be supplied to different curing lamps d, and heated water from different curing lamps d to flow back to the heated water return pipe C02. Alternatively, the water-cooling passage d02 of one curing lamp d can be configured with both a cold water outlet pipe C01 and a heated water return pipe C02, which also enables the return of heated water.

[0096] The circulating cooling terminal C is equipped with a cold medium inlet pipe C1 and a heat exchange heating medium outlet pipe C2. A first flow detection valve C10 is installed on the cold medium inlet pipe C1, and a second flow detection valve C20 is installed on the heat exchange heating medium outlet pipe C2. The flow rate detected by the first flow detection valve C10 and the flow rate detected by the second flow detection valve C20 must be the same. If they are not the same, it indicates that there is a leak. When a leak is found, the main valve installed on the cold medium inlet pipe C1 will be closed.

[0097] Specifically, such as Figure 8 , Figures 13-19 As shown, each curing lamp d includes a plurality of spaced-apart light emitters d11, and at least a portion of the spaced-apart light emitters d11 emit light rays that overlap. The curing lamp d also includes a lamp body d1 with a light emitter mounting chamber d10. The lamp body d1 includes a heat dissipation main frame d01, which has a ring-shaped or rectangular structure, depending on the actual working environment.

[0098] For example, it includes a ring-shaped heat dissipation main frame and a straight rectangular ring-shaped heat dissipation main frame, with the ring-shaped heat dissipation main frame located at the top and the straight rectangular ring-shaped heat dissipation main frame located below at least a few sides of the ring-shaped heat dissipation main frame to form curing in multiple orientations.

[0099] like Figures 13-19 As shown, several light-emitting bodies d11 are installed in the light-emitting body mounting chamber d10 at intervals. The light-emitting bodies d11 are distributed in a straight line or in a ring, depending on the structure of the heat dissipation frame d01.

[0100] The emitted light rays from 4-N light emitters d11, arranged at intervals, overlap. The overlap of emitted light rays from multiple light emitters d11 creates a high overlap rate, which can compensate for the fact that the curing lamp cannot achieve ideal working efficiency due to the attenuation of the illumination light from a single light emitter, and can effectively improve the effective energy utilization rate of the curing lamp.

[0101] like Figure 18As shown, in the first case, the light emitter d11 has a emission angle of 30°, and the emitted light rays from 4-8 light emitters d11 arranged in sequence overlap. A preferred embodiment is that the emitted light rays from 6 light emitters d11 arranged in sequence overlap.

[0102] like Figure 19 As shown, the second type: the light emitter d11 has a 60° emission angle, and the emitted light rays of 10-16 light emitters d11 arranged in sequence overlap. The preferred embodiment is: the emitted light rays of 13 light emitters d11 arranged in sequence overlap.

[0103] like Figures 13-19 As shown, a light outlet d12 is provided on the lamp body d1, and the light-emitting side of the light-emitting body d11 faces the light outlet d12. The light outlet d12 is a rectangular elongated opening. A closure d13 made of transparent or light-transmitting material is installed in the light outlet d12. The closure d13 is, for example, a quartz rod.

[0104] The cross-section of the closure d13 can be either a semi-circular surface or a cylindrical surface. It acts similarly to a convex lens. Of course, the closure d13 can also be a rectangular cross-section.

[0105] The method of using the modular UV curing component in this embodiment includes the following steps:

[0106] S1. The movable UV component carrier plate g1 extends at least part of itself outside the UV lamp box 2, the product to be cured is fixed on the product fixture of the UV component carrier plate g1 extending outside the UV lamp box 2, and the UV component carrier plate g1 is driven to move the product to be cured into the UV lamp box 2.

[0107] UV lamp box 2 in S2 and S1 performs UV treatment on the product to be cured. During and / or after the UV treatment, air cooling is used to cool the internal space of UV lamp box 2.

[0108] S3. After the UV treatment is completed in step S2, the UV component carrier plate g1 moves the cured product to outside the UV lamp box 2.

[0109] The above describes the curing cycle for a product to be cured. Example 2

[0110] Based on Example 1, such as Figure 15As shown, the lamp body d1 in this embodiment includes a heat dissipation main frame d01, within which a water-cooling passage d02 is provided. The water-cooling passage d02 can be either a straight water-cooling passage or a ring-shaped water-cooling passage, and its shape is determined by the structure of the heat dissipation main frame d01. Both ends of the water-cooling passage d02 are connected to water pipes, allowing water to flow within the passage and exchange heat with the heat dissipation main frame d01. In other words, water cooling is used to lower the temperature of the UV lamp box 2, thereby extending the service life of the curing lamp. Example 3

[0111] Based on Embodiment 1 and Embodiment 2, as Figure 8 and Figure 9 As shown, in this embodiment, the UV light box 2 is fixed to the pull-out base plate g2 by a UV fixing frame 21. The structure of the UV fixing frame 21 includes two oppositely distributed lateral supports 210 and an end support 211 located between the opposite ends of the two lateral supports 210. A horizontal support 212 is provided on the top of the two lateral supports 210 and the top of the end support 211. A curing lamp d is provided on the inner side of each lateral support 210 and on the inner side of the end support 211. A hollow area is provided on the horizontal support 212, and a curing lamp d is provided on the horizontal support 212. The lamp d has a ring-shaped structure. Ultraviolet light emitted by the curing lamp d shines downwards from the hollowed-out area. A lamp box door assembly c is located at one end of the sliding base plate g2's travel distance. Lamp box door assembly c is a lifting door, driven by a cylinder or hydraulic cylinder to open and close. When lamp box door assembly c is open, the UV component carrier plate g1 can at least partially extend outside the UV lamp box 2. A control box b is located at the other end of the travel distance on the sliding base plate g2. Control box b, for example, is an electrical control box. Control box b is connected to the curing lamp d and to the carrier plate translation driver g3. A water-cooling passage d02 is connected to a pipeline via a quick-connect coupling. The pipeline passes through the control box b and is a heat exchange pipe, which cools the interior of the control box b. Example 4

[0112] Based on the above embodiments one, two, and three, as follows Figure 20 and Figure 25 As shown, this embodiment provides a multi-cavity UV curing processing unit, which can also be called a processing equipment. This multi-cavity UV curing processing unit includes the multi-cavity UV curing processing cooling system XT described in Embodiments 1, 2, and 3.

[0113] The multi-cavity UV curing processing unit also includes a frame A1, on which a curing component fixing frame A2 is provided, and on the curing component fixing frame A2 are a plurality of curing component mounting positions A20. The modular UV curing component A of Embodiment 1 is installed in the curing component mounting position A20.

[0114] Secondly, a circulating cooling terminal C and a cooling air supply terminal B are provided at the top of the curing component mounting bracket A2. This top-to-bottom arrangement allows for more efficient use of the internal space of the rack. Meanwhile, a control module group 10 is located at the bottom of the rack A1 to prevent the heat dissipation temperature of the modular UV curing component A from affecting the performance of the control module group 10.

[0115] like Figures 20-24 As shown, in order to prevent leaked water from dripping and damaging the control module group 10 at the bottom of the unit, this embodiment further provides a water leakage protection structure. Specifically, a water leakage protection device is provided on the frame A1 below the curing component fixing frame A2. The water leakage protection device includes a flow guide plate e1 located in the frame A1 and a collection container e2 located at the water outlet of the flow guide plate e1. The collection container e2 is connected to the discharge pipe e3. A liquid level sensor e4 and a drain valve e5 are installed on the discharge pipe e3. The liquid level sensor e4 is used to detect the water level stored in the discharge pipe e3 after the drain valve e5 is closed.

[0116] like Figures 20-24 As shown, the leakage protection structure includes a flow guide plate e1 installed in the frame A1. The flow guide plate e1 is a rectangular plate. Three sides of the flow guide plate e1 are sealed to the inner wall of the frame A1, and the remaining side has a gap with the inner wall of the frame A1, which forms the water outlet.

[0117] The flow guide plate e1 is fixed to the frame A1 by any of the following methods: welding, bolting, or bracketing. The flow guide plate e1 divides the interior of the frame A1 into an upper chamber and a lower chamber, and the upper chamber and the lower chamber are connected, with the connection point being the aforementioned water outlet.

[0118] In order to prevent the water from flowing freely downwards, a collection container e2 is provided at the water outlet of the guide plate e1. The collection container e2 collects the leaked water and has a disc-shaped structure.

[0119] The collection container e2 can be set to a horizontal or tilted state. Of course, when there are multiple collection containers e2, one collection container e2 can be in a horizontal state while another collection container e2 is tilted. Alternatively, the bottom of the collection container e2 can be tilted, which can also serve as a water flow guide.

[0120] In order to promptly detect whether there is a leak and whether the leaked water needs to be discharged, this embodiment further designs a structure in which the collection container e2 is connected to the discharge pipe e3. The discharge pipe e3 is set at an incline or vertical position, and the water in the collection container e2 can be discharged directly through the discharge pipe e3. A liquid level sensor e4 and a drain valve e5 are installed on the discharge pipe e3. The liquid level sensor e4 is used to detect the water level stored in the discharge pipe e3 after the drain valve e5 is closed.

[0121] Drain valve e5 is an electrically controlled valve. Both the level sensor e4 and drain valve e5 are communicatively connected to control module group 10, such as a PLC control module, using wired or wireless transmission methods. When the level sensor e4 detects the set liquid level, drain valve e5 opens to drain; otherwise, it closes. Water discharged from drain pipe e3 can be connected to a floor drain via a water pipe, or it can be manually collected in a bucket using drain pipe e3.

[0122] The collection container e2, combined with the discharge pipe e3, liquid level sensor e4, and drain valve e5, can collect leaked water and provide feedback on the liquid level. It can detect whether there is a leak and whether the leak needs to be discharged, thus ensuring the service life of the unit and maintaining the cleanliness of the bottom surface of the working environment.

[0123] In another embodiment, the flow guide plate e1 has multiple water outlets, and each water outlet is provided with a corresponding collection container e2. Specifically, the flow guide plate e1 in this embodiment has two water outlets.

[0124] like Figures 20-24 As shown, specifically, one collecting container e2 is directly fixed below the flow guide plate e1, and the collecting container e2 is connected to the water outlet of the flow guide plate e1. A water outlet through-hole e10 penetrating the thickness of the flow guide plate e1 is provided on the flow guide plate e1, and the collecting container e2 is located at the lower opening of the water outlet through-hole e10. The number of water outlet through-holes e10 is 1-N; of course, the hole diameters can be the same or different, as long as water can be discharged.

[0125] The collection container e2 in this method is formed by stamping a metal sheet. Reinforcing ribs e20 are provided on the inner wall of the collection container e2. These reinforcing ribs e20 divide the collection container e2 into several sub-chambers, and all sub-chambers are interconnected. The reinforcing ribs e20 can strengthen the structure of the collection container e2. For example, the reinforcing ribs e20 may be in the shape of a cross.

[0126] like Figures 20-24 As shown, specifically, the other collection container e2 is guided by the inclined flow guide component e6. That is, the inclined flow guide component e6 is located below the other water outlet of the flow guide plate e1, and the collection container e2 receives the water drained by the inclined flow guide component e6. The structure of this other water outlet is as follows: the flow guide plate e1 has several water outlet slots e11 on one circumferential side, and the upper end of the inclined flow guide component e6 is located below the lower slot of the water outlet e11. The water outlets e11 discharge the water, and the water is guided by the inclined flow guide component e6 into the other collection container e2.

[0127] The tilting guide assembly e6 is fixed to the frame A1 by two connecting arms e60.

[0128] By designing the two schemes above, leakage in different areas can be diverted and collected for treatment, thereby improving efficiency.

[0129] Secondly, such as Figure 24 As shown, the inclined guide component e6 can be either an inclined guide plate or an inclined guide channel. The inclined guide plate is a flat plate structure, while the inclined guide channel can be a structure with a cross-section of V-shape or U-shape, etc.

[0130] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
