Among them, the non-destructive laser scribing is widely used in the process of dividing the solar cell as an accurate and efficient processing method. The traditional non-destructive laser scribing technology usually includes two stages of laser heating and cold water jet cooling, so as to generate a transient temperature gradient in the cell and form a tensile stress, thereby realizing the fracture of the cell. After the cold water jet cooling, a large amount of water mist is often left on the metal carrier, if the residual water mist is not removed in time, it will affect the subsequent process, at the same time, the long-term water mist residue will also accelerate the corrosion of the carrier and other components, thereby increasing the maintenance cost of the equipment. SUMMARY

[0003] The main purpose of the present application is to provide a drying equipment to solve the problem of accelerated corrosion of the carrier and other components caused by the water mist on the carrier in the prior art, thereby increasing the maintenance cost of the equipment.

[0004] In order to achieve the above purpose, according to one aspect of the present application, a drying equipment is provided, which is used for drying a drying carrier carrying a cell, and an air inlet and an air outlet are arranged on the drying carrier and communicate with the outside. The drying equipment comprises:

[0005] A pipeline assembly, one end of the pipeline assembly communicates with the air inlet, and the other end of the pipeline assembly away from the air inlet is used for communicating with a heat source equipment, so as to introduce the heat source in the heat source equipment into the drying carrier through the pipeline assembly, so as to dry the drying carrier.

[0006] Further, the pipeline assembly comprises a first conveying pipeline, and the inlet end of the first conveying pipeline communicates with the heat source equipment.

[0007] A second conveying pipeline, the inlet end of the second conveying pipeline communicates with the first conveying pipeline, and the outlet end of the second conveying pipeline is used for communicating with the air inlet, so as to introduce the heat source into the drying carrier through the first conveying pipeline and the second conveying pipeline.

[0008] Further, the second conveying pipeline is a plurality of second conveying pipelines, the outlet ends of the plurality of second conveying pipelines all communicate with the drying carrier, and the inlet ends of the plurality of second conveying pipelines all communicate with the first conveying pipeline.

[0009] Furthermore, the piping assembly includes multiple third conveying pipes, the outlet ends of which are connected to the drying platform, and the inlet ends of which are connected to the heat source equipment, so as to introduce the heat source into the drying platform through the multiple third conveying pipes.

[0010] Furthermore, the drying equipment also includes a transfer component, the two ports of which are connected to the pipe assembly and the drying platform respectively, so as to introduce the heat source into the drying platform through the pipe assembly via the transfer component.

[0011] Furthermore, the flow cross-section of the adapter is between 5.5mm and 6.5mm.

[0012] Furthermore, the adapter and the drying platform are integrally formed, or the adapter and the drying platform are detachably formed.

[0013] Furthermore, the adapter has a first connection position and a second connection position at the air inlet. The first connection position and the second connection position are threaded together to install the adapter on the drying platform.

[0014] Furthermore, the drying equipment also includes a noise reduction component, which is disposed on at least one of the first conveying pipe and the second conveying pipe to reduce the noise of the heat source entering the drying platform; and / or, the noise reduction component is disposed at the air outlet.

[0015] Furthermore, the drying equipment also includes a noise reduction component, which is installed on the third conveying pipe to reduce the noise of the heat source entering the drying platform.

[0016] Furthermore, the drying equipment also includes a temperature measuring component, which is installed on the drying platform to measure the real-time temperature of the drying platform.

[0017] On / off components are installed on the pipe assembly;

[0018] The controller, connected to the temperature sensing element and the on / off element, controls the on / off state of the piping assembly by controlling the opening degree of the on / off element according to the real-time temperature.

[0019] Furthermore, the drying equipment also includes a heating element, which is installed inside the heat source equipment and connected to the controller. When the real-time temperature is lower than the set temperature, the heating element is controlled to heat the heat source so that the heat source is greater than or equal to the set temperature.

By setting air inlets and outlets on the drying stage and configuring pipeline components connected to the heat source equipment, the heat source of the equipment itself is effectively utilized, avoiding the corrosion problem of the stage and other components caused by the inability to dry the existing water mist in time in the prior art. This also reduces the maintenance cost of the equipment. Furthermore, this drying method can not only significantly improve the drying speed and reduce energy consumption, but also optimize the vacuum adsorption performance, ensure the precise positioning of the solar cells during the scribing process, improve cutting accuracy and yield, and significantly reduce the frequency of equipment maintenance.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] In the solar cell manufacturing industry, quartoking technology has become one of the mainstream processes to improve cell conversion efficiency and reduce costs. Among these processes, non-destructive laser scribing, as a precise and efficient processing method, is widely used in the quartoking of solar cells. Traditional non-destructive laser scribing technology typically involves two stages: laser heating and cold water jet cooling. This creates an instantaneous temperature gradient inside the cell, generating tensile stress and causing the cell to fracture. After cold water jet cooling, a large amount of water mist often remains on the metal stage. This not only increases the energy consumption and time of subsequent drying steps, but more importantly, the residual moisture affects the vacuum adsorption performance of the stage, leading to unstable cell positioning during the scribing process, thus affecting the cutting accuracy and yield of the cells. Furthermore, long-term moisture residue can accelerate the corrosion of the stage and its related components, increasing equipment maintenance costs.

[0030] However, existing technologies often use resistance wire heating for drying. During this process, direct contact between the resistance wire and the metal carrier can lead to electrical leakage. Furthermore, the resistance wire is prone to damage over time, requiring periodic replacement, which is neither economical nor safe. Therefore, the main objective of this technical solution is to provide a drying device for drying the drying carrier 1 that holds the battery cells, such as... Figure 1 and Figure 2 As shown, the drying platform 1 is equipped with an air inlet 2 and an air outlet, both of which can be connected to external equipment. The drying equipment includes a vacuuming structure for evacuating air. A vacuum adsorption component is provided on the drying platform 1, and the vacuum adsorption component has multiple vacuum adsorption holes. The air outlet of the vacuuming structure is connected to the vacuum adsorption component to evacuate the vacuum adsorption component. The battery cells are placed on the vacuum adsorption component and above the multiple vacuum adsorption holes. By evacuating the vacuum adsorption component, the vacuum adsorption component gradually presents a negative pressure state, thereby enabling the cells on the vacuum adsorption component to be vacuumed. The battery cells are adsorbed to prevent them from shifting during subsequent operations. At the same time, the vacuuming equipment generates a heat source, i.e., hot air, while vacuuming. To avoid wasting this resource, this heat source needs to be recycled and introduced into the drying platform 1 to dry the platform. Specifically, the drying equipment includes a pipe assembly 3. One end of the pipe assembly 3 is connected to the air inlet 2, and the end of the pipe assembly 3 away from the air inlet 2 is connected to the heat source equipment, so that the heat source in the heat source equipment is introduced into the drying platform 1 through the pipe assembly 3 to dry the platform.

[0031] Optionally, the drying equipment in this technical solution can be applied to multi-cell batteries, such as two-cell, three-cell, four-cell, etc.

[0032] The heat source device is the aforementioned vacuum structure.

[0033] Alternatively, the heat source device can also be a separate device used to generate heat, independent of the vacuum structure.

[0034] Furthermore, when the heat source device is the aforementioned vacuum structure, the pipe assembly 3 includes a first conveying pipe 31 and a second conveying pipe 32. The inlet end of the first conveying pipe 31 is connected to the outlet end of the heat source device, the inlet end of the second conveying pipe 32 is connected to the outlet end of the first conveying pipe 31, and the outlet end of the second conveying pipe 32 is used to connect to the air inlet 2, so as to introduce the heat source into the drying platform 1 through the first conveying pipe 31 and the second conveying pipe 32.

[0035] The reuse of the drying platform 1 by utilizing the heat source of the vacuum structure not only saves energy costs but also effectively improves the drying speed of the platform, ensures the positional stability of the cells under vacuum adsorption, reduces positioning errors caused by moisture during the dicing process, and thus improves dicing accuracy and cell yield.

[0036] Optionally, there are multiple second conveying pipes 32. The inlet end of each second conveying pipe 32 is connected to the first conveying pipe 31, and the outlet end of each second conveying pipe 32 is connected to the first conveying pipe 31. That is, the heat source is first conveyed to the first conveying pipe 31, and then the heat source is diverted to multiple second conveying pipes 32 by the first conveying pipe 31.

[0037] This two-stage pipeline design further optimizes the heat source transmission efficiency. The first conveying pipeline 31 ensures effective concentration of the heat source, while the second conveying pipeline 32 achieves precise distribution of the heat source, avoiding unnecessary waste of heat energy. At the same time, it ensures uniform heating of all parts of the drying platform 1, enhancing the drying effect and the operational stability of the equipment.

[0038] Furthermore, the pipeline assembly 3 includes multiple third conveying pipelines, the inlet ends of which are all connected to the drying platform 1 and the heat source equipment, so that the heat source can be introduced into the drying platform 1 through the multiple third conveying pipelines. In this case, there are multiple air inlets 2 set on the drying platform 1, and the number of air inlets 2 is the same as the number of third conveying pipelines. The multiple air inlets 2 are set one-to-one with the multiple third conveying pipelines. Each third conveying pipeline is connected to its corresponding air inlet 2, that is, the heat source only enters into the third conveying pipeline and is transported to the drying platform 1 by the third conveying pipeline.

[0039] The use of multiple direct third-line delivery pipes improves the heat transfer speed and thermal efficiency, ensuring timely hot air supply to each air inlet 2 and accelerating the drying process. Simultaneously, this design facilitates equipment maintenance and upgrades, as a failure in any single pipe will not affect the entire system, enhancing equipment reliability.

[0040] Furthermore, the drying equipment also includes a transfer component 4, which consists of multiple transfer components. Each transfer component is configured to correspond one-to-one with a third conveying pipe. The inlet end of each transfer component 4 is connected to its corresponding third conveying pipe, so that the heat source in the third conveying pipe can be introduced into the drying platform 1 through the transfer component 4.

[0041] The use of adapter 4 makes the pipe connection more precise, effectively reducing energy loss at the connection point. By precisely controlling the speed and amount of hot air entering the third conveying pipe through each adapter 4, the temperature consistency of each area on the drying platform 1 is ensured, further improving drying efficiency and the consistency of the cells after dicing.

[0042] Furthermore, when the pipeline assembly 3 includes a first conveying pipeline 31 and a second conveying pipeline 32, there is one adapter 4. The inlet end of the adapter 4 is connected to the outlet end of the first conveying pipeline 31, and the outlet end of the adapter 4 is connected to the air inlet 2.

[0043] Using a connecting component 4 as an intermediate component between the first conveying pipe 31 and the second conveying pipe 32 simplifies the pipe structure and reduces equipment complexity and maintenance costs. At the same time, this design ensures uniform heat source distribution, facilitates centralized control of hot air flow and temperature, and improves drying stability and efficiency.

[0044] Furthermore, the flow cross-section of each of the aforementioned adapter components 4 is between 5.5mm and 6.5mm.

[0045] Optionally, the flow cross section of each of the above-mentioned adapter components 4 is 6mm.

[0046] Controlling the flow cross-section of the transfer component 4 helps regulate the pressure and flow rate of the hot air, ensuring that the hot air entering the drying platform 1 does not generate excessive resistance, nor does it lose too much heat energy due to an excessively large flow cross-section. This maintains the temperature of the hot air while preventing excessive airflow from affecting the stability of vacuum adsorption, thus achieving a balance between efficient heat source utilization and safe equipment operation.

[0047] Furthermore, the adapter 4 and the drying platform 1 are integrally formed, or the adapter 4 and the drying platform 1 are detachably formed.

[0048] The adapter 4 has a first connection position 41 and a second connection position is provided at the air inlet 2. The first connection position 41 and the second connection position are threaded together to install the adapter 4 on the drying platform 1. Specifically, the first connection position 41 is an external thread provided on the adapter 4, and the second connection position is an internal thread engraved on the inner wall of the air inlet 2. The internal thread and the external thread are threaded together.

[0049] The one-piece molding design enhances the connection between the adapter 4 and the drying platform 1, reducing the possibility of heat leakage and ensuring the overall sealing of the system. The detachable design facilitates equipment maintenance and repair; any faulty or worn component can be replaced without downtime or replacement of the entire drying platform 1, effectively shortening maintenance time and reducing operating costs. The threaded installation combines the advantages of both: a robust connection and easy disassembly and assembly, improving equipment maintenance efficiency and lifespan.

[0050] Furthermore, the drying equipment also includes a noise reduction component 5, which is disposed on at least one of the first conveying pipe 31 and the second conveying pipe 32 to reduce the noise of the heat source entering the drying platform 1; and / or, the noise reduction component 5 is disposed at the air outlet.

[0051] The application of silencer component 5 reduces the noise generated during the operation of the piping system, providing a better working environment for operators and reducing occupational fatigue and noise pollution. Furthermore, the silencer measures at the air outlet prevent noise from affecting surrounding equipment, ensuring the overall smooth operation of the production line.

[0052] Optionally, the silencing component 5 can be simultaneously installed on the first conveying pipe 31 and the second conveying pipe 32.

[0053] Optionally, the silencing component 5 can also be installed on the third conveying pipe.

[0054] Preferably, the silencing component 5 is located at the inlet end of the third conveying pipe.

[0055] Preferably, the silencing component 5 is located at the outlet end of the third conveying pipe.

[0056] Preferably, the silencing component 5 is installed at both the inlet and outlet ends of the third conveying pipe.

[0057] By placing the silencing components 5 at the inlet and outlet of all heat source conveying pipes, system noise can be reduced comprehensively, ensuring that the equipment maintains low-noise operation during multiple operating stages. In particular, the silencing components 5 on the third conveying pipe directly reduce noise pollution around the drying platform 1.

[0058] Furthermore, the drying equipment also includes a temperature measuring component, which is installed on the drying platform 1 to measure the real-time temperature of the drying platform 1.

[0059] On / off component, the on / off component is installed on pipe assembly 3;

[0060] The controller, connected to the temperature measuring component and the on / off component, controls the on / off state of the pipe assembly 3 by controlling the opening degree of the on / off component according to the real-time temperature.

[0061] The temperature sensing component detects the real-time temperature of the drying platform 1 and transmits the information to the controller. The controller automatically adjusts the on / off components according to the preset temperature target to control the supply of hot air. This intelligent design ensures precise temperature control during the drying process, avoiding damage to the solar cells or insufficient drying due to excessively high or low temperatures, thereby greatly improving drying efficiency and the quality of the solar cells after dicing.

[0062] Optionally, the switching component is a valve.

[0063] Furthermore, the drying equipment also includes a heating element installed inside the vacuum equipment. The heating element is connected to the controller to control the heating element to heat the heat source when the real-time temperature is lower than the set temperature, so that the heat source is greater than or equal to the set temperature.

[0064] The addition of heating elements ensures that the hot air temperature is always maintained within a set, highly efficient drying range. Even in low-temperature environments, it can quickly raise the temperature of the drying platform 1, achieving rapid and thorough drying. The controller's intelligent control capability allows the heating elements to start or stop as needed, avoiding overheating, saving energy, reducing equipment operating costs, and protecting the equipment from damage caused by excessively high heat source temperatures.

[0065] Optionally, the heating component can be a heat exchange heater or other component capable of heating.

[0066] Alternatively, the heating element can also be housed in a separate heat source device.

[0067] Furthermore, the drying equipment also includes a cooling assembly installed within the vacuum equipment. The cooling assembly is connected to the controller and includes a heat exchanger, a cooling water tank, a first pipe, a second pipe, and a temperature detection component. The temperature detection component is installed on the second heat exchange pipe. One end of the first pipe is connected to the inlet of the cooling water tank, and one end of the second pipe is connected to the outlet of the cooling water tank. The heat exchanger has a first heat exchange channel and a second heat exchange channel. The two ends of the first heat exchange channel are connected to the first pipe and the second pipe, respectively, to allow the cold source to flow within the first heat exchange channel. The inlet of the second heat exchange channel... The first heat exchange channel is connected to the heat source equipment, and the outlet end of the second heat exchange channel is connected to the pipe assembly 3. At the same time, the pipe assembly 3 is also connected to the outlet end of the heat source equipment. A first on / off component is provided on the first conveying pipe 31 and the third conveying pipe of the pipe assembly 3, and a second on / off component is provided on the first heat exchange channel and the second heat exchange channel. When the real-time temperature of the drying platform 1 is lower than the set temperature, the first on / off component is in the open state and the second on / off component is in the closed state. The heat source generated by the heat source equipment directly enters the drying platform 1 through the pipe assembly 3 to dry the drying platform 1.

[0068] When the real-time temperature of the drying platform 1 is greater than the set temperature, the controller controls the first on / off component to be in the closed state and the second on / off component to be in the open state. In this case, the heat source generated by the heat source device will not directly enter the drying platform 1. Instead, the heat source will be initially cooled by the cooling component and then transported to the drying platform 1 through the pipe assembly 3. During this process, the temperature detection component installed on the second heat exchange pipe will detect the temperature inside the second heat exchange pipe. When the temperature of the heat source inside the second heat exchange pipe reaches the temperature threshold required by the drying platform 1, the controller will gradually control the first on / off component to switch from the open state to the closed state, and at the same time, the second on / off component will switch from the closed state to the open state, so as to transport the heat source after heat exchange to the drying platform 1.

[0069] Optionally, when the real-time temperature of the drying platform 1 is greater than the set temperature, the controller will control the opening degree of the first on / off component and the second on / off component to simultaneously input the heat source directly generated by the heat source device and the heat source after heat exchange into the drying platform 1, that is, to mix the two heat sources of different temperatures and then convert them into the temperature of the heat source input into the drying platform 1. In this process, the controller will dynamically control the opening degree of the first on / off component and the second on / off component according to the measurement results of the temperature measuring component set on the drying platform 1, so that the temperature of the heat source entering the drying platform 1 reaches the temperature threshold required by the drying platform 1 as much as possible.

[0070] By integrating a cooling component into the drying equipment and linking it with a controller, precise control and efficient regulation of the temperature of the drying platform 1 are achieved, significantly improving the yield and quality of solar cell production. When the temperature of the drying platform 1 is low, the heat source equipment directly heats the equipment to ensure rapid temperature rise to meet drying requirements. When the temperature is too high, the heat source is initially cooled by the cooling component, and then precise temperature detection and dynamic adjustment ensure that the temperature of the heat source input to the drying platform 1 is stabilized at the required temperature threshold. This temperature control system not only reduces energy waste and achieves energy saving, but also avoids equipment safety hazards caused by temperature fluctuations and extends the service life of the equipment.

[0071] Furthermore, the drying equipment also includes a filter element 6, which is disposed on the pipe assembly 3 to filter the heat source delivered from the heat source equipment to the drying platform 1.

[0072] The filter element 6 effectively removes dust, oil, and other impurities from the heat source, preventing these contaminants from depositing on the drying platform 1. This filtration process also extends the service life of the drying equipment, reduces the risk of pipe blockage and component corrosion, and ensures the long-term stable operation of the system.

[0073] Optionally, the filter element 6 is a filter screen.

[0074] Optionally, the filter element 6 is a filter.

[0075] Furthermore, the drying platform 1 includes multiple drying sub-platforms 11, each drying sub-platform 11 having a drying chamber, each drying chamber being independent of the others, wherein each drying chamber has an air inlet 2 and an air outlet.

[0076] Independent control of each drying unit 11 ensures that one or more drying units 11 can be dried individually. In addition, the non-interconnected chamber design prevents uneven drying or problems caused by malfunctions affecting the entire system, improving equipment stability and fault isolation capabilities, reducing overall maintenance costs and downtime, and enhancing the flexibility and controllability of the production line.

[0077] Optionally, the drying chambers are interconnected.
