Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a curing device. Background Technology

[0002] In battery production, UV curing equipment emits UV light of a specific wavelength. This UV light penetrates the surface of the battery cell, exciting residual photosensitive resin in the slurry, thereby reducing contact resistance, forming a dense polymer network, increasing electrode pull strength, and enhancing the adhesion between the electrode and the silicon substrate. Existing UV curing equipment includes a UV lamp and a carrier assembly. The carrier assembly holds the battery to be processed, and the UV lamp faces the battery on the carrier assembly, treating the battery with its emitted UV light.

[0003] However, in existing curing devices, impurities tend to accumulate on the lamp surface during the curing process. As the usage time increases, these impurities accumulate and significantly affect the ultraviolet light irradiation effect, thereby reducing curing quality and efficiency and impacting the performance improvement of solar cells.

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In this application, the terms "upper," "lower," "top," "bottom," "inner," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0029] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0030] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0032] In the manufacturing process of solar cells, electrode formation and performance optimization are crucial factors affecting cell efficiency. While traditional sintering processes can meet certain requirements, they have significant shortcomings in addressing microscopic defects after sintering. On one hand, glass phase migration residue is a common problem. After the glass phase in the silver paste forms an ohmic contact with silicon, stress contraction during cooling can create micron-sized voids, increasing contact resistance and affecting cell performance. On the other hand, electrode adhesion also needs improvement. After high-temperature sintering, the difference in thermal expansion coefficients between the silver layer and the silicon substrate can easily lead to localized delamination, reducing the stability and reliability of the cell.

[0033] The UV curing device emits UV light of a specific wavelength. This high-energy UV light can penetrate the electrode surface and excite residual photosensitive resin (such as acrylate) in the slurry. This causes the photosensitive resin to fill the microcracks inside the electrode, thereby reducing contact resistance. Simultaneously, UV light can crosslink monomers and oligomers in the slurry in a very short time, forming a dense polymer network, increasing electrode tensile strength and enhancing the adhesion between the electrode and the silicon substrate.

[0034] However, existing UV curing devices still have many limitations in practical applications. During the curing process, some impurities tend to float and accumulate on the lamp surface. Over time, these impurities accumulate, significantly affecting the UV irradiation effect, thus reducing curing quality and efficiency, and ultimately impacting the performance of solar cells.

[0035] Based on this, this application discloses a curing device that can keep the surface of the curing lamp clean by using a purging component, ensuring that the irradiation effect is not affected, thereby improving the curing quality and efficiency.

[0036] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0037] Please see Figure 1 and Figure 2 , Figure 1 This is one of the structural schematic diagrams of the curing device 100 provided in the embodiments of this application. Figure 2 This is a second schematic diagram of the curing device 100 provided in the embodiments of this application. This application discloses a curing device 100, which includes: a protective shell 1, comprising a housing 11 and a door 12, the door 12 being movably connected to the housing 11 to open or close the housing 11; a support component 2, disposed inside the housing 11, for supporting a workpiece 200 to be processed, the support component 2 including a clearance portion 21; a photocuring module 3, comprising a first photocuring component 31 and a second photocuring component 32, the first photocuring component 31 being disposed above the support component 2 and used to irradiate the front side of the workpiece 200, the second photocuring component 32 being disposed below the support component 2 and used to irradiate the back side of the workpiece 200; and a purging component 4, used to purge the photocuring module 3 to remove impurities located on the surface of the photocuring module 3; wherein, the clearance portion 21 is configured to allow the light emitted by the second photocuring component 32 to pass through the support component 2 to irradiate the workpiece 200.

[0038] The protective shell 1, serving as the outer casing of the curing device 100, provides physical protection for the photocuring module 3 inside. It also isolates the photocuring module 3 and the workpiece 200 from the external environment, forming a relatively enclosed curing space. This effectively prevents external dust, impurities, and other contaminants from entering the curing area, thus avoiding interference with the curing process and improving the stability of the curing quality.

[0039] The movable connection between the door 12 and the housing 11 makes it easier and faster for operators to maintain the UV curing module 3. When the door 12 is closed, it ensures that the entire curing process takes place in a closed environment, minimizing UV light leakage and ensuring the safety of operators and the surrounding environment. This is especially important for curing devices 100 that use UV light or other harmful light sources, effectively reducing the health risks that operators may face from long-term exposure to UV light.

[0040] Optionally, the height of the protective shell 1 can be two meters, and the length of the protective shell 1 can be three meters. A height of two meters ensures that operators can easily place and remove the workpiece 200, and also provides sufficient space for the internal components to ensure their stable operation. A length of three meters allows the workpiece 200 to remain inside the protective shell 1 for a sufficient time to complete the curing process. For workpieces 200 that require longer light curing times, this length ensures that they receive sufficient ultraviolet radiation when passing through the light curing module 3, thereby achieving a high-quality curing effect.

[0041] The support component 2 is located inside the housing 11. The support component 2 can stably support the workpiece 200 to be processed, ensuring that the workpiece 200 maintains a suitable position and posture during the curing process. The stable position of the workpiece 200 can ensure that the light emitted by the photocuring module 3 can evenly illuminate the surface of the workpiece 200, which helps to improve the uniformity and consistency of the curing effect.

[0042] Furthermore, the clearance section 21 allows the light emitted by the second photocuring component 32 to pass through the carrier component 2 and directly illuminate the back side of the workpiece 200. This ensures that both the front and back sides of the workpiece 200 can receive photocuring treatment simultaneously, achieving the function of simultaneous double-sided curing. Double-sided curing can improve curing efficiency and shorten curing time, thereby improving the efficiency of the entire production process. At the same time, uniform illumination on both sides also helps to improve the curing quality of the workpiece 200, making its performance more stable and reliable.

[0043] The photocuring module 3 consists of a first photocuring component 31 and a second photocuring component 32, located above and below the supporting component 2, respectively. It can simultaneously cure both the front and back sides of the workpiece 200 under photocuring. This bidirectional curing not only improves curing efficiency but also ensures the uniformity of the curing effect. Since both the front and back sides of the workpiece 200 are simultaneously exposed to light under the same process conditions, it avoids the uneven curing problem caused by single-sided light exposure, thus improving the consistency of product quality.

[0044] Specifically, by adjusting parameters such as light intensity, wavelength, and irradiation time of the first photocuring component 31 and the second photocuring component 32, the curing process can be optimized to meet the needs of different workpieces 200 at different process stages. This flexibility and adjustability enable the curing device 100 to adapt to various types of workpieces 200 and different curing processes, giving it a wide range of applications and good adaptability.

[0045] Optionally, the photocuring module 3 can be an LED ultraviolet lamp assembly, which features a stable wavelength range, low heat generation, and long service life, providing high-intensity and uniform ultraviolet light irradiation to effectively excite the photosensitive resin in the workpiece 200 to undergo a curing reaction. Alternatively, the photocuring module 3 can be a mercury lamp assembly, which emits high-intensity ultraviolet light covering a wide wavelength range, suitable for curing various photosensitive materials.

[0046] The curing device 100 in this embodiment has wide applicability and can meet the curing requirements of various workpieces 200. For example, the workpiece 200 can be a solar cell, and the curing device 100 can be used to cure components such as electrodes on the solar cell to improve the performance and stability of the solar cell. During the curing process, fragments of the solar cell may fall onto the surface of the photocuring module 3 due to various reasons (such as mechanical vibration during production, electrostatic adsorption, etc.).

[0047] During the curing process, impurities (such as fragments of battery cells) absorb or block light, causing a decrease in the intensity of light emitted by the photocuring module 3 and reducing the light energy reaching the surface of the workpiece 200, thus affecting the curing effect. The blowing assembly 4 uses dried compressed air or other suitable gases to promptly blow these impurities away from the surface of the photocuring module 3, keeping the photocuring module 3 clean.

[0048] Through continuous purging, the UV curing module 3 maintains excellent light performance throughout the curing process. This not only improves curing quality and efficiency but also helps extend the lifespan of the UV curing module 3, reducing maintenance costs and replacement frequency.

[0049] Thus, the curing device 100 provided in this application embodiment solves the problem of impurities such as battery cell fragments covering the surface of the photocuring module 3 by using the purging component 4, ensuring the cleanliness of the photocuring module 3, maintaining a stable light irradiation effect, extending the service life of the curing device 100 and reducing maintenance costs. On the basis of ensuring operational safety, it improves curing efficiency and quality, enhances the stability and service life of the curing device 100, and reduces production costs.

[0050] Please see Figure 1 and Figure 2In some embodiments, the protective housing 1 includes an air inlet and an air outlet. The air inlet is used to connect to an external air supply device to provide clean gas to the interior of the protective housing 1. The air outlet is located on the upper surface of the protective housing 1 and is used to connect to the external atmosphere. The purging assembly 4 includes a purging pipe 41 located to the side of the second photocuring assembly 32. The air inlet of the purging pipe 41 is connected to the air inlet, and the air outlet of the purging pipe 41 faces the upper surface of the second photocuring assembly 32. The purging pipe 41 is configured to blow clean gas onto the upper surface of the second photocuring assembly 32 to remove impurities located on the upper surface of the second photocuring assembly 32.

[0051] Specifically, the air inlet, connected to an external air supply device, continuously delivers clean gas into the protective shell 1. The air outlet is located on the upper surface of the protective shell 1, making good use of the natural upward flow of gas, allowing the clean gas after purging to be smoothly discharged from the top of the shell 11 and connected to the outside atmosphere. This prevents excessively high air pressure inside the protective shell 1, creating a stable and clean working environment for the curing process and improving the stability of curing quality.

[0052] The purge pipe 41 of the purge assembly 4 is located to the side of the second photocuring assembly 32, enabling the purge pipe 41 to guide cleaning gas to the upper surface of the second photocuring assembly 32. The air inlet of the purge pipe 41 is connected to the air inlet, ensuring a stable supply of cleaning gas, while the orientation of the air outlet ensures that the gas can be blown onto the upper surface of the second photocuring assembly 32 at a suitable flow rate and angle, effectively removing impurities adhering to the upper surface of the second photocuring assembly 32.

[0053] Furthermore, the cleaning gas can create a continuous airflow impact force to purge the battery cell fragments, peeling them off from the surface of the second photocuring component 32 and blowing them away. This prevents the battery cell fragments from adhering to the second photocuring component 32 for a long time due to electrostatic adsorption or other reasons, which would affect the transmission and irradiation effect of ultraviolet light.

[0054] In this way, the purging component 4 not only effectively protects the performance of the second photocuring component 32, but also reduces uneven illumination caused by impurities, ensuring the high efficiency and stability of the curing process. At the same time, timely removal of impurities reduces the risk of premature aging or damage to the second photocuring component 32 due to surface contamination, extends the service life of the photocuring module 3, reduces maintenance costs and curing device downtime, and improves overall production efficiency.

[0055] Please see Figure 1 and Figure 2In some embodiments, the curing device 100 further includes: an exhaust pipe 5, one end of which is connected to the interior of the protective shell 1 through an exhaust port, and the other end of which is connected to the external atmosphere; and an air extraction component disposed in the exhaust pipe, configured to extract gas from the interior of the protective shell 1.

[0056] The exhaust pipe 5 provides a stable outlet for the gas inside the protective shell 1. The exhaust pipe 5, together with the purging pipe 41 and the external air supply equipment, forms a complete airflow circulation system. When clean gas enters the protective shell 1 through the inlet, it creates a certain airflow within the shell 11. This airflow can purge impurities and waste gas from the surface of the second curing component and discharge it into the external atmosphere through the exhaust pipe 5. This prevents excessively high internal pressure within the protective shell 1, ensuring its structural stability and safety.

[0057] Furthermore, the extraction component further enhances the efficiency and controllability of the exhaust system. The extraction component, installed in the exhaust pipe 5, can actively extract gas from inside the protective shell 1, allowing the internal gas to be discharged quickly and stably. This effectively prevents the internal pressure of the protective shell 1 from rising, ensuring that the protective shell 1 is always within a suitable working pressure range.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the housing 11 includes an upward opening, and the curing device 100 further includes a moving mechanism 6 disposed on the housing 11 and connected to the door 12. The moving mechanism 6 is configured to move the door 12 toward or away from the housing 11 in a vertical direction so that the door 12 covers or leaves the opening. When the door 12 covers the opening, the housing 11 is closed; when the door 12 leaves the opening, the housing 11 is open.

[0059] The housing 11 has an upward opening, providing a convenient passage for the placement and removal of the photocuring module 3. This allows operators to easily place the first photocuring component 31 into or remove it from the carrier component 2, improving the convenience of installation and maintenance. It also facilitates the maintenance and repair of the various components inside the housing 11, reducing the downtime of the curing device 100.

[0060] The moving mechanism 6 enables automated control of the door 12. Connected to the door 12, the moving mechanism 6 drives the door 12 vertically, allowing it to cover or move away from the opening of the housing 11. When the door 12 covers the opening, the housing 11 is closed, ensuring the curing process takes place in a sealed environment, preventing ultraviolet light leakage, ensuring operator safety, and preventing external impurities from entering the housing 11 and interfering with the curing process. Conversely, when it is necessary to place or remove the first photocuring component 31, the moving mechanism 6 can move the door 12 away from the opening, opening the housing 11 and providing unobstructed access for the operator.

[0061] Furthermore, the automated control of the moving mechanism 6 enhances the stability and reliability of the curing device 100. By precisely controlling the opening and closing of the door 12, the curing process can be automated, reducing human intervention and the risk of operational errors.

[0062] Please see Figure 1 and Figure 2 In some embodiments, the moving mechanism 6 includes a hydraulic arm 61, which has a fixed part 611 and a movable part 612. The fixed part 611 is connected to the housing 11, and the movable part 612 is connected to the door 12. The movable part 612 is movably disposed on the fixed part 611 in the vertical direction to drive the door 12 to move closer to or away from the housing 11 in the vertical direction. There are two hydraulic arms 61, and the two hydraulic arms 61 are arranged at intervals along the width direction of the housing 11.

[0063] The hydraulic arm 61 ensures the stability and precision of the opening and closing action of the door 12. The hydraulic arm 61 consists of a fixed part 611 and a movable part 612. The fixed part 611 is connected to the housing 11, providing a stable support base for the entire hydraulic arm 61. The movable part 612 is connected to the door 12 and can move vertically on the fixed part 611, allowing the door 12 to approach or move away from the opening of the housing 11 in a smooth and controllable manner.

[0064] When the movable part 612 moves the door 12 downward, the door 12 can tightly cover the opening of the housing 11, ensuring the sealing of the protective housing 1; while when the movable part 612 moves upward, the door 12 can completely leave the opening, providing an unobstructed access path for the operator, improving the convenience of operation, reducing the shaking and impact of the door 12 during opening and closing, and extending the service life of the curing device 100.

[0065] Two hydraulic arms 61 are arranged at intervals along the width of the housing 11, further enhancing the stability and uniformity of the opening and closing of the door 12. The symmetrical distribution of the two hydraulic arms 61 in the width direction ensures uniform force distribution on the door 12 in the vertical direction, avoiding tilting or jamming of the door 12 due to uneven force distribution at a single point. This ensures that the door 12 remains stable during opening and closing, improving the reliability of the moving mechanism 6.

[0066] Meanwhile, the coordinated work of the two hydraulic arms 61 can provide greater support and driving force, enabling the door 12 to overcome its own weight and possible frictional resistance more easily, thereby achieving smoother opening and closing actions.

[0067] Please see Figure 1 and Figure 2 In some embodiments, the curing device 100 further includes a cooling component 7, which is disposed on the photocuring module 3 and is thermally connected to the photocuring module 3. The cooling component 7 is used to absorb the heat emitted by the photocuring module 3.

[0068] The cooling component 7 is thermally conductively connected to the photocuring module 3, enabling the cooling component 7 to absorb the heat dissipated by the photocuring module 3 during operation. The photocuring module 3 generates a large amount of heat during operation. If this heat cannot be dissipated in time, it may cause the temperature of the photocuring module 3 to become too high, thereby affecting the performance and service life of the photocuring module 3.

[0069] The cooling component 7 absorbs and conducts heat, transferring heat energy from the UV curing module 3 to itself. The heat is then dissipated into the environment through an internal heat dissipation mechanism, thus maintaining the operating temperature of the UV curing module 3 within a suitable range. This helps extend the lifespan of the UV curing module 3, reduces component damage and frequent replacements due to overheating, and ensures the UV curing module 3 can continuously and stably perform, improving curing quality and efficiency.

[0070] The cooling component 7 also helps improve the operational stability and safety of the entire curing device 100. Inside the enclosed protective housing 1, heat accumulation can cause internal temperature to rise, affecting the normal operation of other components and potentially posing safety hazards. The cooling component 7, through effective thermal management, reduces the temperature inside the protective housing 1, minimizing problems such as component aging and material deformation caused by high temperatures, thus improving the overall reliability of the curing device 100.

[0071] Please see Figure 1 and Figure 2In some embodiments, the housing 11 includes a liquid inlet and a liquid outlet, and the cooling assembly 7 includes: a first cooling pipe 71, one end of which is connected to the liquid inlet and the other end of which is connected to the liquid outlet, so that the cooling medium passes through the first cooling pipe 71 and is discharged from the liquid outlet; the outer surface of the first cooling pipe 71 is attached to the non-irradiated surface of the first photocuring assembly 31 so that the cooling medium in the first cooling pipe 71 absorbs the heat emitted by the first photocuring assembly 31; and a second cooling pipe 72, one end of which is connected to the liquid inlet and the other end of which is connected to the liquid outlet, so that the cooling medium passes through the second cooling pipe 72 and is discharged from the liquid outlet; the outer surface of the second cooling pipe 72 is attached to the non-irradiated surface of the second photocuring assembly 32 so that the cooling medium in the second cooling pipe 72 absorbs the heat emitted by the second photocuring assembly 32.

[0072] The inlet and outlet on the housing 11 provide channels for the entry and exit of the cooling medium, ensuring a continuous flow of the cooling medium through the cooling pipes. The first cooling pipe 71 and the second cooling pipe 72 are connected to the inlet and outlet respectively, forming two independent and parallel cooling circuits. This allows the cooling medium to flow simultaneously through the non-irradiated surfaces of the first photocuring component 31 and the second photocuring component 32, effectively absorbing the heat dissipated by the two photocuring components during operation. As the cooling medium flows through the cooling pipes, it carries away heat from the photocuring components through thermal conduction, reducing the temperature of the photocuring components and thus protecting the photocuring module 3 from overheating damage.

[0073] In the structure of the photocuring module 3, each photocuring component typically has two main surfaces. The irradiated surface is the side that directly faces the workpiece 200 and emits light for curing, while the non-irradiated surface is the opposite side and does not participate in the direct photocuring process. During operation, the non-irradiated surface usually accumulates more heat because it is not directly exposed to light and is more exposed to the surrounding environment. By installing cooling pipes on the non-irradiated surface, heat can be effectively dissipated from this side, achieving efficient heat dissipation.

[0074] The outer surfaces of the first cooling pipe 71 and the second cooling pipe 72 are tightly bonded to the non-irradiated surfaces of the first photocuring component 31 and the second photocuring component 32, respectively. This ensures good thermal contact between the cooling pipes and the photocuring components, improving heat transfer efficiency. The cooling medium circulates within the cooling pipes, continuously absorbing and carrying away the heat generated by the photocuring components, thus achieving rapid and uniform heat dissipation. This extends the service life of the photocuring components and ensures that the photocuring module 3 operates at a stable operating temperature, improving curing quality and efficiency.

[0075] Please see Figure 1 and Figure 2 In some embodiments, the first photocuring component 31 includes a plurality of first ultraviolet lamps 311, which are disposed on the housing 11 and located above the support component 2, and the plurality of first ultraviolet lamps 311 are arranged at intervals along the length of the housing 11.

[0076] The first UV curing assembly 31 consists of multiple first UV lamps 311, which are disposed inside the housing 11 and above the support assembly 2. The multiple first UV lamps 311 are arranged at intervals along the length of the housing 11, which helps to expand the light coverage area, ensuring that the workpiece 200 can receive UV light irradiation uniformly along its length. This not only improves curing efficiency but also ensures the consistency of the curing effect, avoiding curing defects caused by uneven light irradiation.

[0077] Please see Figure 1 and Figure 2 In some embodiments, the second photocuring component 32 includes a plurality of second ultraviolet lamps 321, which are disposed on the housing 11 and located below the support component 2, and the plurality of second ultraviolet lamps 321 are arranged at intervals along the length of the housing 11.

[0078] Similarly, the second UV curing assembly 32 consists of multiple second UV lamps 321, which are disposed within the housing 11 and located below the support assembly 2. The multiple second UV lamps 321 are arranged at intervals along the length of the housing 11, which helps to expand the light coverage area, ensuring that the workpiece 200 receives UV light irradiation uniformly along its length. This not only improves curing efficiency but also ensures the consistency of the curing effect, avoiding curing defects caused by uneven light distribution.

[0079] Furthermore, the multi-lamp layout enhances the flexibility and adaptability of the curing device 100. By adjusting the power and irradiation time of each UV lamp, precise curing of workpieces 200 of different sizes and shapes can be achieved. For example, for a longer workpiece 200, the arrangement of multiple UV lamps ensures sufficient illumination along its entire length without insufficient light.

[0080] Optionally, the first ultraviolet lamp 311 and the second ultraviolet lamp 321 can also be connected to a control unit to adjust the irradiation power. The control unit allows the operator to flexibly adjust the irradiation power of the first ultraviolet lamp 311 and the second ultraviolet lamp 321 according to different workpieces 200 and process requirements. The power range can be set from 50-700W, covering a variety of application scenarios from low power to high power.

[0081] This adjustable power design not only improves the adaptability and versatility of the curing device 100, but also optimizes the curing effect. By precisely controlling the irradiation power, it can be ensured that the workpiece 200 is cured under optimal light conditions, thereby improving product quality and consistency. In addition, precise power control also helps extend the lifespan of the UV lamp, as excessive power use may accelerate lamp aging, while reasonable power adjustment can reduce this loss.

[0082] Please see Figure 1 and Figure 2 In some embodiments, the photocuring module 3 further includes a first protective element 312, which is disposed on the irradiation surface of the first ultraviolet lamp 311 and is a light-transmitting element.

[0083] The first protective component 312 effectively protects the first ultraviolet lamp 311. During the operation of the curing device 100, when the workpiece 200 is being cured, fragments or other foreign objects may be generated. The first protective component 312 can prevent these fragments from directly impacting the first ultraviolet lamp 311, thereby reducing the risk of lamp damage and extending the service life of the first ultraviolet lamp 311. In addition, the first protective component 312 can also prevent dust, oil, and other impurities from adhering to the surface of the lamp tube, avoiding affecting the emission efficiency and uniformity of light.

[0084] Furthermore, since the first protective component 312 is a light-transmitting component, it will hardly block or absorb the light emitted by the first ultraviolet lamp 311, ensuring that most of the ultraviolet light can pass through smoothly and irradiate the workpiece 200. The workpiece 200 can receive sufficient and uniform light, thereby ensuring the stability and reliability of the curing effect.

[0085] Furthermore, the presence of the first protective component 312 facilitates the maintenance and cleaning of the first ultraviolet lamp 311. Since the first protective component 312 is located on the irradiation surface of the first ultraviolet lamp 311, it can directly contact fallen fragments or impurities. Operators only need to clean or replace the first protective component 312 periodically to maintain the good working condition of the entire photocuring module 3, without having to directly contact the ultraviolet lamp, thus reducing maintenance difficulty and safety risks.

[0086] Please see Figure 1 and Figure 2 In some embodiments, the photocuring module 3 further includes a second protective component 322, which is disposed on the irradiation surface of the second ultraviolet lamp 321 and is a light-transmitting component.

[0087] The second protective component 322 effectively protects the second ultraviolet lamp 321. During the operation of the curing device 100, fragments or other foreign objects may be generated when the workpiece 200 is cured. The second protective component 322 can prevent these fragments from directly impacting the second ultraviolet lamp 321, thereby reducing the risk of lamp damage and extending the service life of the second ultraviolet lamp 321. In addition, the second protective component 322 can also prevent dust, oil, and other impurities from adhering to the lamp surface, avoiding affecting the light emission efficiency and uniformity.

[0088] Furthermore, since the second protective component 322 is a light-transmitting component, it will hardly block or absorb the light emitted by the second ultraviolet lamp 321, ensuring that most of the ultraviolet light can pass through smoothly and irradiate the workpiece 200. The workpiece 200 can receive sufficient and uniform light, thereby ensuring the stability and reliability of the curing effect.

[0089] Furthermore, the presence of the second protective component 322 facilitates the maintenance and cleaning of the second ultraviolet lamp 321. Since the second protective component 322 is located on the irradiation surface of the second ultraviolet lamp 321, it can directly contact fallen fragments or impurities. Operators only need to clean or replace the second protective component 322 periodically to maintain the good working condition of the entire photocuring module 3 without directly contacting the ultraviolet lamp, thus reducing maintenance difficulty and safety risks.

[0090] Optionally, the first protective element 312 and the second protective element 322 can be tempered glass. Tempered glass has high strength and impact resistance, effectively protecting the first ultraviolet lamp 311 and the second ultraviolet lamp 321 from external mechanical damage. Simultaneously, tempered glass has excellent light transmittance, ensuring that the light emitted by the ultraviolet lamps efficiently passes through the protective elements and irradiates the surface of the workpiece 200. Furthermore, tempered glass also has a certain degree of heat resistance, which can, to some extent, resist the heat generated during the operation of the photocuring module 3.

[0091] Please see Figure 1 and Figure 2 In some embodiments, the housing 11 is provided with an inlet 111 and an outlet 112, which are located on two opposite sides of the housing 11 along its length, and the photocuring module 3 is located between the inlet 111 and the outlet 112; the carrier component 2 includes a conveyor belt and a drive component, the conveyor belt is provided on the housing 11 and extends from the inlet 111 to the outlet 112, the drive component is connected to the conveyor belt and is used to drive the conveyor belt to rotate so that the conveyor belt moves the workpiece 200 to be processed from the inlet 111 to the outlet 112.

[0092] The housing 11 has an inlet 111 and an outlet 112, which are located on opposite sides of the housing 11 along its length. This allows the workpiece 200 to enter and exit the curing device 100 in a straight path, facilitating integration with equipment in other production processes (such as feeders and unfeeders) and achieving automation and continuity in the production process. The photocuring module 3 is located between the inlet 111 and the outlet 112, ensuring that the workpiece 200 receives sufficient photocuring treatment as it passes through the housing 11, thus guaranteeing the curing effect.

[0093] The conveyor belt in the carrier assembly 2 is located inside the housing 11 and extends from the inlet 111 to the outlet 112, forming a continuous conveying path. The conveyor belt is connected to a drive unit, which rotates the conveyor belt, thereby stably conveying the workpiece 200 to be processed from the inlet 111 to the outlet 112. This not only improves the stability of the workpiece 200 during the curing process but also reduces manual intervention and the risk of operational errors. The conveyor belt can carry multiple workpieces 200, enabling batch processing and improving production efficiency.

[0094] Furthermore, the use of a conveyor belt enhances the applicability and flexibility of the curing device 100. By adjusting the speed of the conveyor belt and the rotation speed of the drive components, it can accommodate workpieces 200 with different curing time requirements, enabling the curing device 100 to meet diverse production needs.

[0095] Optionally, the conveyor belt can be two sub-conveyor belts spaced apart along the width of the protective shell 1, with the clearance portion 21 forming the gap between the two sub-conveyor belts. The gap between the two sub-conveyor belts forms the clearance portion 21, providing a channel for light to penetrate the carrier assembly 2. This allows the light emitted by the second photocuring assembly 32 to pass smoothly through the carrier assembly 2 and illuminate the back side of the workpiece 200. This not only achieves the effect of simultaneous curing on both sides of the workpiece 200, but also improves curing efficiency and quality, resulting in more uniform and thorough curing.

[0096] The alternating arrangement of the two sub-conveyor belts increases the overall flexibility and adaptability of the conveyor belt system. When placing and conveying workpieces 200 of different sizes or shapes, this spacing design avoids blocking light, ensuring that each workpiece 200 receives sufficient illumination. Furthermore, the alternating arrangement of the two sub-conveyor belts reduces wear on the conveyor belt surface during cleaning.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
