[0043] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the UV curing apparatus 100 provided in the embodiments of this application. Figure 2 This is a side view of the UV curing apparatus 100 provided in an embodiment of this application. The UV curing apparatus 100 provided in this application includes a frame 10, a feeding mechanism 20, a curing mechanism 30, and a cooling mechanism 40. The feeding mechanism 20 is mounted on the frame 10 and conveys the workpiece 200 along a first horizontal direction X. The curing mechanism 30 is mounted on the frame 10 and includes a curing lamp 31. The curing lamp 31 is used to cure the workpiece 200 on the feeding mechanism 20. An air inlet 311 and an air outlet 312 are formed on the curing lamp 31.

[0044] The cooling mechanism 40 is mounted on the frame 10. The cooling mechanism 40 includes an air supply component 41 and an exhaust component 42. The air supply component 41 is positioned toward the air inlet 311 to supply cold air to the curing lamp 31, and the exhaust component 42 is positioned toward the air outlet 312 to extract heat from the curing lamp 31.

[0045] Specifically, the frame 10, serving as the mounting base for the entire UV curing device 100, can be welded from high-strength steel. The feeding mechanism 20 is mounted on the frame 10 and conveys the workpiece 200 along the first horizontal direction X, such as... Figure 1 As shown, the first horizontal direction X can be from left to right. The workpiece 200 includes, but is not limited to, cylindrical battery cells, and other cylindrical or irregularly shaped products requiring UV coating curing.

[0046] In some embodiments, the feeding mechanism 20 may be a conveyor belt structure. The conveyor belt is driven by a motor mounted on the frame 10 and connected to the rollers of the conveyor belt via a chain or belt to achieve uniform speed operation of the conveyor belt.

[0047] In some embodiments, the feeding mechanism 20 includes a track extending along a first horizontal direction X and a carrier mounted on the track, the carrier carrying the workpiece 200 to be cured. The carrier is driven by a motor mounted on the carrier, thereby enabling transport movement along the track.

[0048] The curing lamp 31 can be, but is not limited to, an electrodeless lamp, a mercury lamp, a metal halide lamp, a xenon lamp, a UV LED lamp, etc. The air inlet 311 and the air outlet 312 on the curing lamp 31 can be respectively set on both sides of the curing lamp 31. The air inlet 311 is used to receive cold air, and the air outlet 312 is used to exhaust the hot air after absorbing heat, so that the airflow forms a circulation inside the curing lamp 31, thereby improving the heat dissipation efficiency.

[0049] The curing mechanism 30 can be equipped with multiple curing lamps 31, such as 2, 3, or 4, to enhance the intensity of the UV light emitted by the curing mechanism 30. The specific number can be adjusted according to the actual curing requirements.

[0050] The cooling mechanism 40 may be equipped with an adjusting valve on the air supply component 41, which can be adjusted to control the air supply volume to meet the heat dissipation requirements of different curing lamps 31.

[0051] In some embodiments, the exhaust assembly 42 may be connected to an outdoor exhaust gas treatment device to further treat the exhaust hot air and reduce its environmental impact.

[0052] In actual operation, the workpiece 200 is placed on the feeding mechanism 20, which moves the workpiece 200 along the first horizontal direction X. When the workpiece 200 enters the curing area between the curing mechanisms 30, the curing lamp 31 emits UV light to the workpiece 200 to cure it. The air supply component 41 and the exhaust component 42 of the cooling mechanism 40 work together. The air supply component 41 inputs cold air into the air inlet 311 of the curing lamp 31. The cold air absorbs the heat generated by the curing lamp 31 as it flows through it, and then carries the heat out from the air outlet 312. The exhaust component 42 promptly extracts this hot air to ensure that the curing lamp 31 is always at a suitable working temperature.

[0053] In summary, in the UV curing device 100 of this application, the air supply component 41 inputs cold air towards the air inlet 311 of the curing lamp 31, and the exhaust component 42 extracts heat in a timely manner from the corresponding air outlet 312, so as to stabilize and control the working temperature of the curing lamp 31 within a reasonable range, thereby ensuring the service life of the curing lamp 31, ensuring the stability of the curing effect, and improving the curing qualification rate of the workpiece.

[0054] Please see Figure 3 , Figure 3 This is an exploded view of the curing mechanism 30 provided in the embodiment of this application. Optionally, the curing lamp 31 includes an irradiation section 313, which is disposed opposite to the air inlet 311 and adjacent to the air outlet 312.

[0055] When the air supply assembly 41 delivers cold air into the curing lamp 31 through the air inlet 311, the cold air enters from the side away from the irradiation section 313 and flows along the internal cavity of the curing lamp 31 to the air outlet 312 adjacent to the irradiation section 313. During this process, the cold air can fully flow through the heating elements of the irradiation section 313, such as UV lamp beads or lamp tubes, and absorb the heat generated by the irradiation section 313 during operation to the greatest extent, thus preventing heat from accumulating around the irradiation section 313.

[0056] The air outlet 312 located near the irradiation unit 313 can quickly discharge the hot air after absorbing heat, reduce the secondary heat exchange between the hot air and the irradiation unit 313, further improve the cooling efficiency of the irradiation unit 313, and ensure that the irradiation unit 313 is always in a stable operating temperature range, which not only ensures the output intensity of UV light, but also extends the service life of the curing lamp 31.

[0057] Optionally, there are two air outlets 312, which are spaced apart on both sides of the irradiation section 313. The air outlets 312 on both sides can quickly discharge the hot air after absorbing heat, reduce the residence time of the hot air inside the curing lamp 31, and further improve the heat exchange efficiency.

[0058] When the cold air enters from the air inlet 311 opposite to the irradiation part 313, it will flow along both sides inside the curing lamp 31 to the corresponding air outlet 312. The cold air can evenly cover the heat-generating areas on both sides of the irradiation part 313, avoiding the problem of uneven heat dissipation on one side caused by a single air outlet 312.

[0059] Please see Figure 1 , Figure 4 and Figure 5 , Figure 4 This is another structural schematic diagram of the UV curing apparatus 100 provided in the embodiments of this application. Figure 5 This is another structural schematic diagram of the UV curing device 100 provided in the embodiments of this application. Optionally, the UV curing device 100 includes two curing mechanisms 30, which are arranged along the second horizontal direction Y and disposed on both sides of the feeding mechanism 20. Each set of curing mechanisms 30 is provided with a cooling mechanism 40.

[0060] The dual curing mechanism can simultaneously cure the workpiece 200 conveyed by the feeding mechanism 20 on both sides, greatly improving the curing efficiency of the workpiece 200 and ensuring that the curing uniformity is consistent on both sides of the workpiece 200. Each cooling mechanism 40 corresponds to a curing mechanism 30, ensuring that the heat generated by the curing mechanisms 30 on both sides can be discharged independently.

[0061] Two curing mechanisms 30 are respectively arranged on both sides of the feeding mechanism 20 along the second horizontal direction Y, which is perpendicular to the first horizontal direction X, i.e., the front-to-back direction. When the workpiece 200 enters the curing area between the curing mechanisms 30, the curing lamps 31 on both sides emit UV light to both sides of the workpiece 200 to perform dual-sided synchronous curing treatment on the workpiece 200.

[0062] Optionally, the curing lamp 31 includes a mounting portion 314 connected to the irradiation portion 313. The irradiation portion 313 protrudes from the mounting portion 314 and is disposed towards the feeding mechanism 20. The irradiation portion 313 and the mounting portion 314 form a recess 315. The irradiation portion 313 protrudes relative to the mounting portion 314 towards the feeding mechanism 20, so that the UV light can act more directly on the surface of the workpiece 200.

[0063] The two curing mechanisms 30 include a first curing mechanism 30a and a second curing mechanism 30b. The first curing mechanism 30a and the second curing mechanism 30b are inclined relative to the feeding mechanism 20 and have different installation heights. The irradiation part 313 of the first curing mechanism 30a is at least partially housed in the recessed part 315 of the second curing mechanism 30b, and the mounting part 314 of the second curing mechanism 30b is at least partially housed in the recessed part 315 of the first curing mechanism 30a.

[0064] The first curing mechanism 30a may be slightly higher than the second curing mechanism 30b, and their tilt directions are opposite to form a staggered layout. This staggered layout of the first and second curing mechanisms 30a reduces the distance between them, allowing the irradiation sections 313 on both sides to be closer to the workpiece 200, thus enhancing the intensity and coverage of UV light. Simultaneously, the nesting of the first and second curing mechanisms 30a reduces the overall space occupied by the curing mechanisms 30 in the second horizontal direction Y, making the structure of the UV curing device 100 more compact.

[0065] Please see Figure 2 Optionally, each air supply assembly 41 includes a cooling element 411 and an air supply duct 412. The cooling element 411 is mounted on the frame 10 and is connected to the inlet of the air supply duct 412. The outlet of the air supply duct 412 is set towards the air inlet 311. The cooling element 411 delivers cold air to the curing lamp 31 through the air supply duct 412.

[0066] After the cooling component 411 is activated, the cold air generated is delivered to the air inlet 311 of the curing lamp 31 via the air supply pipe 412. After the cold air flows through the heating element inside the curing lamp 31, the heat can be discharged from the air outlet 312, forming a continuous cooling cycle. This provides the curing lamp 31 with low and stable cold air, improving the cooling effect.

[0067] Specifically, the refrigeration unit 411 can be a small industrial air conditioner, and it can be fixedly mounted on the frame 10. The air outlet of the refrigeration unit 411 and the inlet of the air supply duct 412 can be sealed together by a flange or snap-fit ​​structure to prevent leakage during the delivery of cold air.

[0068] Understandably, the cooling component 411 has a temperature regulation function, which can adjust the temperature of the output cold air in real time according to the temperature of the curing lamp 31. When the temperature of the curing lamp 31 is detected to be too high, the cold air temperature is automatically reduced, and vice versa, so as to ensure the cooling effect and avoid energy waste.

[0069] Optionally, a regulating valve may be installed at the outlet of the air supply duct 412. The regulating valve is used to control the air supply volume of the air supply duct 412 to adapt to the heat dissipation requirements of curing lamps 31 with different power. An angle adjusting component may be installed on the air supply duct 412 to adjust the angle of the outlet of the air supply duct 412 so that the air supply duct 412 is accurately oriented towards the air inlet 311 of the curing lamp 31.

[0070] Please see Figure 4 Optionally, in each curing mechanism 30, there are multiple curing lamps 31 arranged along the first horizontal direction X. When the workpiece 200 is conveyed by the feeding mechanism 20 along the first horizontal direction X through the curing mechanism 30, it can be continuously irradiated by multiple curing lamps 31 in sequence, thereby improving the curing effect by extending the action time of UV light.

[0071] Each air supply assembly 41 includes multiple air supply pipes 412. In each set of air supply pipes 412, the multiple air supply pipes 412 are arranged along the first horizontal direction X and are all connected to the cooling component 411. The air supply pipes 412 correspond one-to-one with the air inlets 311, and the outlets of the air supply pipes 412 are set towards the corresponding air inlets 311.

[0072] The one-to-one air supply design of the air supply duct 412 and the air inlet 311 can avoid the problem of uneven air distribution when multiple curing lamps 31 share a single air supply duct 412, ensuring that each curing lamp 31 can obtain a sufficient and stable amount of cold air.

[0073] Specifically, in each air supply assembly 41, the number of air supply ducts 412 corresponds to the number of air inlets 311 of the curing lamps 31 within the corresponding curing mechanism 30. The air supply ducts 412 can be branched according to the number and layout of the corresponding curing lamps 31. The inlet of each air supply duct 412 is connected to the cooling component 411, and the outlet corresponds one-to-one with the air inlet 311 of the corresponding curing lamp 31. When a certain air supply duct 412 becomes blocked or damaged, it can be disassembled and replaced individually without affecting the heat dissipation effect of other curing lamps 31.

[0074] The number of curing lamps 31 can be 2, 3, 4, or 5, etc., and there is no restriction here. The number of curing lamps 31 can be increased or decreased according to the curing efficiency requirements, and the number of air supply ducts 412 can be increased or decreased accordingly.

[0075] For example, when each curing unit 30 is provided with 6 curing lamps 31 arranged along the first horizontal direction X, each group of air supply components 41 is also provided with 6 air supply pipes 412. The 6 air supply pipes 412 are arranged in parallel and connected to the cooling component 411, and respectively supply air to the 6 curing lamps 31 independently.

[0076] Optionally, each exhaust assembly 42 includes a fan 421 and an exhaust duct 422. The fan 421 is mounted on the frame 10 and connected to the outlet of the exhaust duct 422. The inlet of the exhaust duct 422 is connected to the air outlet 312. The fan 421 extracts heat from the curing lamp 31 through the exhaust duct 422. When the curing lamp 31 generates heat during operation, the fan 421 starts to create negative pressure through the exhaust duct 422, drawing the high-temperature air inside the curing lamp 31 out of the air outlet 312 and quickly exhausting it to the outside or a designated heat dissipation channel.

[0077] Specifically, the fan 421 can be bolted to the side or top of the frame 10. The fan 421 can be a centrifugal fan or an axial fan, depending on the required exhaust volume and installation space. When the fan 421 is working, it can extract the hot air that has undergone heat exchange inside the curing lamp 31 through the exhaust pipe 422 and discharge it to the outside, preventing heat from accumulating inside the device.

[0078] Optionally, each set of exhaust components 42 includes multiple exhaust pipes 422. In each set of exhaust pipes 422, the multiple exhaust pipes 422 are arranged along the first horizontal direction X and are all connected to the fan 421. The exhaust pipes 422 correspond one-to-one with the air outlets 312, and the inlet of the exhaust pipe 422 is connected to the corresponding air outlet 312.

[0079] The one-to-one exhaust design between the exhaust duct 422 and the air outlet 312 of the curing lamp 31 can avoid the problem of uneven exhaust resistance when multiple curing lamps 31 share the exhaust duct 422, and ensure that the hot air inside each curing lamp 31 can be smoothly discharged, which is especially suitable for the situation of multiple lamp groups densely arranged.

[0080] Specifically, in each set of exhaust components 42, the number of exhaust pipes 422 is consistent with the number of air outlets 312 of the curing lamps 31 in the corresponding curing mechanism 30. Multiple exhaust pipes 422 are arranged sequentially along the first horizontal direction X, with one end of each exhaust pipe 422 connected to the air inlet of the fan 421, and the other end connected to the corresponding air outlet 312 of the curing lamp 31. If an exhaust pipe 422 becomes blocked or damaged, it can be disassembled and replaced individually without affecting the heat dissipation effect of other curing lamps 31.

[0081] Please see Figure 3Optionally, the curing mechanism 30 includes a mounting cover 32 connected to the frame 10. The curing lamp 31 is at least partially housed within the mounting cover 32. The mounting cover 32 has an opening 321 on the side facing the feeding mechanism 20. The curing lamp 31 cures the workpiece 200 through the opening 321. A light-blocking plate 33 is slidably disposed on the mounting cover 32, and the light-blocking plate 33 slides relative to the mounting cover 32 to block and expose the opening 321. The light-blocking plate 33 can prevent UV light from causing aging effects on other components of the UV curing device 100 when the curing lamp 31 is continuously on, and reduce the safety risk of operators being exposed to UV light.

[0082] The mounting cover 32 adopts a metal frame structure to provide stable support for the curing lamp 31. The curing lamp 31 is installed inside the mounting cover 32. The mounting cover 32 has an opening 321 on the side facing the feeding mechanism 20 that is adapted to the irradiation range of the curing lamp 31, so that the UV light generated by the curing lamp 31 can pass through the opening 321 and irradiate the workpiece 200 on the feeding mechanism 20.

[0083] The light-blocking plate 33 and the mounting cover 32 are connected by a slide rail and slider structure, allowing them to slide in a direction perpendicular to or inclined to the feeding direction. The sliding of the light-blocking plate 33 can be achieved by a driving component such as a cylinder or motor, which can be installed on the side of the mounting cover 32.

[0084] When the workpiece 200 on the feeding mechanism 20 has not moved to the curing station, the light-blocking plate 33 slides to cover the opening 321, completely blocking the UV light inside the mounting cover 32 to prevent light leakage. When the workpiece 200 is conveyed to the curing station, the light-blocking plate 33 slides away from the opening 321 along the slide rail, exposing the opening 321 so that the UV light can normally irradiate the workpiece 200.

[0085] Please see Figure 5 and Figure 6 , Figure 6 Provided for the embodiments of this application Figure 5 An enlarged schematic diagram of part A of the UV curing apparatus 100. Optionally, the UV curing apparatus 100 includes a reflective assembly 50 mounted on the frame 10, the reflective assembly 50 being located on the side of the feeding mechanism 20 opposite to the curing lamp 31.

[0086] The reflective assembly 50 includes a first adjusting member 51 and a reflector 52 movably connected to the first adjusting member 51. The first adjusting member 51 is mounted on the frame 10. The reflector 52 is arranged parallel to the plane where the opening 321 is located. The reflector 52 and the curing lamp 31 face each other to perform curing treatment on the workpiece 200.

[0087] When the curing lamp 31 emits UV light through the opening 321 onto the workpiece 200, the reflector 52 reflects the UV light hitting its own surface back to the workpiece 200. This allows the workpiece 200 to complete the curing process under the combined action of the direct light from the curing lamp 31 and the reflected light from the reflector 52. This increases the effective range of the UV light, compensates for any potential insufficient illumination on the side of the workpiece 200 facing away from the curing lamp 31, and improves curing uniformity and efficiency. The tilt angle of the reflector 52 and its distance from the workpiece 200 can be adjusted using the first adjusting member 51 according to the shape and size of the workpiece 200.

[0088] Specifically, the first adjusting member 51 can adopt a bracket structure with a locking knob, which is fixedly installed on the frame 10 and located on the side of the feeding mechanism 20 away from the corresponding curing mechanism 30. The reflector 52 is movably connected to the first adjusting member 51. The first adjusting member 51 can drive the reflector 52 to rotate at multiple angles and make fine adjustments to its position. After adjustment, it is fixed by the locking knob.

[0089] Optionally, the UV curing apparatus 100 includes a temperature measuring component 60, which is mounted on the frame 10 and spaced apart from the curing mechanism 30. The temperature measuring component 60 includes a second adjusting member 61 and a temperature measuring element 62 movably connected to the second adjusting member 61. The second adjusting member 61 is mounted on the frame 10, and the temperature measuring element 62 is used to measure the temperature of the workpiece 200 on the feeding mechanism 20. Supported by the second adjusting member 61, the temperature measuring element 62 can measure the temperature of the curing area of ​​the workpiece 200 to monitor the temperature change of the workpiece 200 in real time during the curing process.

[0090] Specifically, the second adjusting member 61 can be a telescopic bracket with angle adjustment function, which is bolted to the frame 10. The second adjusting member 61 can be installed between the two curing mechanisms 30 or on the side above the feeding mechanism 20. The temperature measuring element 62 can be a non-contact infrared temperature sensor, which can monitor the surface temperature of the workpiece 200 in real time without contacting the workpiece 200, thus avoiding the displacement of the workpiece 200 due to contact.

[0091] The height, angle, and detection distance of the temperature measuring element 62 can be flexibly adjusted according to the size, shape, and conveying speed of the workpiece 200 through the adjustment function of the second adjusting element 61. For example, if multiple points of the workpiece 200 need to be detected, the temperature measuring element 62 can be moved by the second adjusting element 61 to achieve a large-area scan.

[0092] Please see Figure 7 , Figure 7This is another structural schematic diagram of the UV curing apparatus 100 provided in the embodiments of this application. Optionally, the UV curing apparatus 100 further includes a protective cover 70, which covers the frame 10 to form a receiving space 701. The protective cover 70 has an inlet 702 and an outlet (not shown) communicating with the receiving space 701. The inlet 702 and the outlet are arranged along a first horizontal direction X. The feeding mechanism 20 passes through the inlet 702 and the outlet and enters the receiving space 701. The curing mechanism 30 is received in the receiving space 701. The air supply assembly 41 and the exhaust assembly 42 are at least partially received in the receiving space 701.

[0093] The enclosure space 701 formed by the protective cover 70 can reduce the interference of external airflow on the air supply component 41 and the exhaust component 42, ensuring that the air supply component 41 and the exhaust component 42 can stably and efficiently dissipate heat for the curing lamp 31 and maintain a stable internal temperature environment.

[0094] The protective cover 70 can adopt a composite structure with double-layer metal plates filled with heat insulation cotton in the middle, which can effectively block the leakage of UV light and reduce the transfer of internal heat to the external environment. It can be equipped with an openable maintenance door on the side or top to facilitate maintenance of internal components such as curing lamp 31, feeding mechanism 20 and cooling mechanism 40.

[0095] The cooling component 411 of the air supply assembly 41 and the fan 421 of the exhaust assembly 42 can be installed outside the protective cover 70 to prevent the cooling component 411 and the fan 421 from being directly affected by the high temperature and UV light inside the protective cover 70. The cooling component 411 can be connected to the air supply pipe 412 inside the protective cover 70 through a pipe, and the fan 421 can also be connected to the exhaust pipe 422 inside the protective cover 70 through a pipe.

[0096] The above are merely preferred embodiments of this application and do not limit the scope of the patent application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of this application.
