[0034] In the current solar cell chain wet production process, the cell is transmitted on the roller, after etching, cleaning and other processes, the cell is blown dry by using the air knife assembly.The air knife assembly includes an upper air knife and a lower air knife, and the upper air knife and the lower air knife blow hot air to the two sides of the cell to dry the cell.However, in order to quickly dry the cell, the air knife has large air volume and fast air speed, and the existing roller design forms a relatively closed space between the roller and the cell, and a large amount of airflow directly impacts on the cell, which is easy to make the cell jump, causing the cell damage, and even the cell breakage, affecting the yield rate;When the cell breakage occurs, it may cause the blocking problem, which needs manual cleaning, increasing the production time and production cost.
[0035] In order to solve the above problems, such as Figures 1-2As shown, the embodiment provides a drying mechanism for battery piece, which comprises a blowing assembly 1 and a plurality of rollers 2. The blowing assembly 1 has two air outlets opposite along the Z-axis direction, which are an upper air outlet and a lower air outlet respectively. The battery piece 100 is located between the two air outlets. The blowing assembly 1 blows air flow to the battery piece 100 through the air outlets to dry the battery piece 100. The plurality of rollers 2 are arranged on both sides of the blowing assembly 1 along the X-axis direction, and each roller 2 is used to support the battery piece 100. The outer periphery of each roller 2 has a flow guide groove 21, and the air flow generated by the lower air outlet can flow out through the flow guide groove 21. The blowing assembly 1 can blow air to both surfaces of the battery piece 100, forming all-round drying of the battery piece 100, increasing the contact area between the air flow and the battery piece 100, and thus improving the drying efficiency. The plurality of rollers 2 are used to support the battery piece 100 together, ensuring the stability of the battery piece 100 during transmission. By arranging the flow guide groove 21 on the outer periphery of the roller 2, the air flow generated by the lower air outlet can flow out through the flow guide groove 21, avoiding the direct impact of a large amount of air flow generated by the lower air outlet on the battery piece 100, reducing the jumping of the battery piece 100 caused by the impact of the air flow, and thus reducing the risk of damage and fragmentation of the battery piece 100, improving the yield, reducing the manual cleaning time and production cost caused by the fragmentation problem, and also making the air flow generated by the lower air outlet more evenly distributed below the battery piece 100, improving the drying effect.
[0036] In an optional embodiment, as shown in Figure 1 、 Figure 2 The roller 2 comprises a supporting part 22 and a flow guide part 23. The supporting part 22 is used to support the battery piece 100. The outer periphery of the flow guide part 23 is recessed relative to the outer periphery of the supporting part 22 to form the flow guide groove 21. The supporting part 22 is used to directly support the battery piece 100. The outer periphery of the flow guide part 23 is recessed relative to the outer periphery of the supporting part 22, that is, the flow guide part 23 does not directly contact the battery piece 100 to form the flow guide groove 21, so that the air flow generated by the lower air outlet can flow out along the flow guide groove 21 after cooling the battery piece 100, reducing the direct impact of the air flow on the battery piece 100.
[0037] In the embodiment, the outer periphery diameter of the supporting part 22 is 40 mm, and the outer periphery diameter of the flow guide part 23 is 34 mm, so that the formed flow guide groove 21 has a groove depth of 7 mm. It should be noted that the outer periphery diameters of the supporting part 22 and the flow guide part 23 are determined by actual needs, and the embodiment does not limit them.
[0038] Further, as shown in Figure 2As shown, the number of supporting portions 22 and flow guide portions 23 is multiple, and the multiple supporting portions 22 and the multiple flow guide portions 23 are sequentially arranged along the axial direction of the roller 2. The multiple supporting portions 22 arranged along the axial direction can more effectively disperse the load borne by the roller 2, so that the roller 2 can more stably support the battery sheet 100; the multiple flow guide portions 23 arranged along the axial direction help to guide the airflow to pass through the multiple flow guide grooves 21 in an orderly manner, reduce the turbulence of the airflow, improve the flow guide efficiency, and prevent the airflow from impacting the battery sheet 100.
[0039] In another optional embodiment, a plurality of grooves are formed in the outer periphery of the roller 2 along the axial direction of the roller 2, and the grooves constitute the flow guide grooves 21. By forming the flow guide grooves 21 by means of the grooves formed in the outer periphery of the roller 2, the airflow is guided to pass along the flow guide grooves 21, avoiding direct impact of the airflow on the battery sheet 100. The groove depth of the grooves is determined according to actual requirements, which is not limited in the embodiment.
[0040] Specifically, as shown in the figure, Figure 1 The drying mechanism of the battery sheet further includes a plurality of pressure rollers 3, and the plurality of pressure rollers 3 are correspondingly arranged above the plurality of rollers 2, and the battery sheet 100 is clamped between the pressure rollers 3 and the rollers 2. The pressure rollers 3 and the rollers 2 jointly clamp the battery sheet 100, so that the battery sheet 100 will not fall off or shift during the drying process due to airflow impact or other factors, and the stability of the battery sheet 100 during the conveying process is ensured.
[0041] Specifically, as shown in the figure, Figure 1 The drying assembly 1 includes two air knives 11 arranged along the Z-axis direction, and the two air knives 11 are respectively an upper air knife and a lower air knife. The upper air knife has an upper air outlet, and the lower air knife has a lower air outlet. In this way, the airflow blows on the two surfaces of the battery sheet 100 from two directions, accelerates the drying process of the battery sheet 100, reduces the time required for drying, and improves the drying effect.
[0042] In the embodiment, as shown in the figure, Figure 1 The drying mechanism of the battery sheet further includes a plurality of conveying rollers 4, and the plurality of conveying rollers 4 are distributed along the conveying direction of the battery sheet 100. The conveying rollers 4 are used to carry and convey the battery sheet 100. The conveying rollers 4 can continuously and stably convey the battery sheet 100, so that the battery sheet 100 can be dried by the airflow generated by the drying assembly 1 under the continuous conveying of the conveying rollers 4, the continuity of the drying process is ensured, and the drying efficiency is improved; the conveying rollers 4 can ensure that the battery sheet 100 remains stable during the conveying process, and by adjusting the distance, speed and rotation mode parameters between the conveying rollers 4, flexible conveying of different specifications of the battery sheet 100 can be realized, and the versatility of the drying mechanism of the battery sheet is improved.
[0043] Further, the roller 2 can rotate around its own axis to convey the battery piece 100. The roller 2 can convey the battery piece 100 together with the conveying wheel 4 while supporting the battery piece 100, thereby reducing the friction between the surface of the battery piece 100 and the roller 2 and further reducing the risk of damage to the battery piece 100.
[0044] Further, the pressing wheel 3 can rotate around its own axis to reduce the friction between the surface of the battery piece 100 and the pressing wheel 3 and further reduce the risk of damage to the battery piece 100.
[0045] Specifically, as shown in Figure 1 The number of the drying assemblies 1 is multiple, and the multiple drying assemblies 1 are distributed along the conveying direction of the battery piece 100. The multiple drying assemblies 1 distributed along the conveying direction can ensure that the battery piece 100 is continuously subjected to the blowing effect during the conveying process, so that the drying and conveying can be performed synchronously, the drying efficiency is improved, and the time required for drying the battery piece 100 is reduced; when a certain drying assembly 1 fails, the other drying assemblies 1 can still continue to work, ensuring that the battery piece 100 can be normally dried, improving the reliability and stability, and reducing the production interruption caused by the failure of the drying assembly 1.
