Abstract
Description
Technical Field
[0001] This application relates to the field of solar cell manufacturing technology, and in particular to a drying apparatus. Background Technology
[0002] A solar cell is a photoelectric device that can convert energy. Under the illumination of sunlight, a solar cell can convert solar energy into electrical energy, thereby generating electricity.
[0003] To improve the absorption rate of sunlight by solar cells, a texturing process is used to form a pyramidal textured surface on the silicon wafer, increasing the surface area and improving power generation efficiency. After texturing, the silicon wafers need to be dried using a drying device. However, when the robotic arm lowers the basket from the slow-lifting trough into the drying tank, residual liquid on the robotic arm drips onto the tank cover, and then onto the silicon wafers inside the drying tank, affecting the yield. Utility Model Content
[0004] Therefore, it is necessary to provide a drying device to prevent residual liquid on the robotic arm from dripping into the drying tank and to ensure a high yield rate.
[0005] A drying apparatus, comprising:
[0006] The tank body is equipped with a drying tank for holding flower baskets;
[0007] The drying tank has two covers, which are openable and closable at the opening of the drying tank. Each cover includes a first cover body and a second cover body. A first side of the first cover body is rotatably connected to a first side of the second cover body, and a second side of the first cover body is rotatably connected to the tank body. A second side of the second cover body is movably disposed on the tank body. The first cover body can rotate relative to the tank body to move the second cover body on the tank body, causing the tank cover to unfold. When the tank cover is unfolded, the first cover body tilts downward toward the tank wall, and the second cover body tilts downward toward the other cover body.
[0008] A flow guide is provided on the second side of the second cover, and the flow guide is used to collect the liquid on the surface of the second cover and discharge the liquid to the outside of the drying tank.
[0009] In one embodiment, the flow guide is provided with a flow guide groove, the opening of which faces the second side of the second cover.
[0010] In one embodiment, the second side of the second cover is disposed within the flow guide groove, and the second cover is inclined toward the bottom of the flow guide groove.
[0011] In one embodiment, the end of the guide member along its length is provided with a drain hole, which is connected to the guide groove.
[0012] In one embodiment, the groove is provided with a guide portion, which is arranged along the opening and closing direction of the groove cover, and the guide portion is guided and engaged with the second side of the second cover.
[0013] In one embodiment, the guide portion is provided with a guide groove, and the second side of the second cover is provided with a guide wheel, the guide wheel being movably disposed in the guide groove; or, the guide portion is provided with a guide rail, and the second side of the second cover is provided with a sliding member, the sliding member being movably disposed on the guide rail.
[0014] In one embodiment, the guide portion is arc-shaped and recessed towards the bottom of the drying tank.
[0015] In one embodiment, there are two guide portions, which are respectively located on opposite sides of the groove; the two ends of the second side of the second cover are respectively guided and engaged with the two guide portions.
[0016] In one embodiment, the drying device further includes a drive member connected to the first cover, the drive member being used to drive the first cover to rotate about a second side of the first cover.
[0017] In one embodiment, the slot cover further includes a rotating shaft, which is rotatably mounted on the slot body, and a second side of the first cover body is fixedly connected to the rotating shaft; the driving component is a cylinder, the power output direction of the cylinder is parallel to the opening and closing direction of the slot cover, the power output shaft of the cylinder is connected to a connecting rod, and the end of the connecting rod opposite to the cylinder is fixedly connected to the rotating shaft.
[0018] In the aforementioned drying device, during the process of the robotic arm placing the basket into the drying tank, when residual liquid from the robotic arm drips onto the surface of the first cover, the liquid on the surface of the first cover flows towards the tank wall to drain the liquid out of the drying tank. When residual liquid from the basket drips onto the surface of the second cover, the liquid on the surface of the second cover flows towards the guide member, which collects the dripping liquid and drains it out of the drying tank. This prevents residual liquid from the robotic arm from dripping into the drying tank, thus preventing liquid from contaminating the silicon wafers and ensuring a high yield rate.

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0024] See Figure 1 The drying apparatus provided in one embodiment of this application includes a tank body 10 and a tank cover 20. The tank body 10 is provided with a drying tank 11 for accommodating a flower basket 40. Two tank covers 20 are provided, and the two tank covers 20 are closablely disposed at the opening of the drying tank 11.
[0025] It should be noted that in actual production, the drying device is usually equipped with 4 to 8 drying tanks 11. When the robotic arm puts the flower basket 40 from the slow lifting trough into the drying tank 11, the cover 20 of one of the drying tanks 11 is opened, and the covers 20 of the remaining drying tanks 11 are closed.
[0026] In one embodiment, see Figure 1 The slot cover 20 includes a first cover body 21 and a second cover body 22. A first side of the first cover body 21 is rotatably connected to a first side of the second cover body 22, a second side of the first cover body 21 is rotatably connected to the slot body 10, and a second side of the second cover body 22 is movably disposed on the slot body 10. The first cover body 21 can rotate relative to the slot body 10 to drive the second cover body 22 to move on the slot body 10, thereby allowing the slot cover 20 to unfold and fold. When the slot cover 20 is unfolded, the first cover body 21 tilts downward toward the slot wall of the slot body 10, and the second cover body 22 tilts downward toward the other second cover body 22.
[0027] It is understandable that when the slot cover 20 is unfolded, the second side of the first cover 21 is lower than the first side of the first cover 21, and the second side of the second cover 22 is lower than the first side of the second cover 22, so that the slot cover 20 as a whole has a shape that is high in the middle and low on both sides.
[0028] Further, see Figure 1 The drying device also includes a guide member 30. The guide member 30 is located on the second side of the second cover 22 and is used to collect the liquid on the surface of the second cover 22 and discharge the liquid to the outside of the drying tank 11.
[0029] It should be noted that the length of the guide 30 is greater than or equal to the length of the second side of the second cover 22.
[0030] When the robotic arm places the basket 40 from the slow-lift trough into the drying tank 11, the cover 20 of one of the drying tanks 11 is opened, while the covers 20 of the remaining drying tanks 11 are closed. When residual liquid on the robotic arm drips onto the surface of the first cover 21, the liquid on the surface of the first cover 21 flows towards the tank wall of the tank 10 to drain the liquid out of the drying tank 11. When residual liquid on the basket 40 drips onto the surface of the second cover 22, the liquid on the surface of the second cover 22 flows towards the guide member 30. The guide member 30 collects the liquid dripping onto the surface of the second cover 22 and drains the liquid out of the drying tank 11. In this way, residual liquid on the robotic arm is prevented from dripping into the drying tank 11, preventing liquid from carrying onto the silicon wafers in the drying tank 11 and ensuring a high yield rate.
[0031] In one embodiment, see Figure 2 The guide member 30 is provided with a guide groove 31, the opening of which faces the second side of the second cover 22. In this way, on the one hand, the liquid on the surface of the second cover 22 can flow into the guide groove 31, where the guide groove 31 temporarily stores the liquid on the surface of the second cover 22; on the other hand, the guide groove 31 can also guide the liquid to be discharged outside the drying tank 11.
[0032] Further, see Figure 2 The second side of the second cover 22 is located inside the flow channel 31, and the second cover 22 is inclined towards the bottom of the flow channel 31. This arrangement facilitates the rapid flow of liquid from the surface of the second cover 22 into the flow channel 31.
[0033] Furthermore, the end of the guide member 30 along its length is provided with a drain hole, which is connected to the guide channel 31. Specifically, the size of the tank cover 20 is slightly larger than the size of the tank body 10, so that the drain hole is located outside the drying tank 11, allowing the liquid in the guide channel 31 to be directly discharged through the drain hole.
[0034] Optionally, drainage holes are provided at both ends of the guide member 30 along its length. This can improve the drainage speed. Of course, in other embodiments, a drainage hole can also be provided at one end of the guide member 30 along its length.
[0035] In one embodiment, the flow guide 30 is detachably mounted on the second side of the second cover 22. This allows the flow guide 30 to be removed from the second cover 22, facilitating maintenance and replacement of the flow guide 30.
[0036] Of course, in other embodiments, the flow guide 30 is integrally formed with the slot cover 20. Specifically, the second side of the second cover 22 is curved upward to form the flow guide 30.
[0037] In one embodiment, the groove 10 is provided with a guide portion, which is arranged along the opening and closing direction of the groove cover 20. A second side of the second cover 22 is provided on the guide portion, and the second side of the second cover 22 is guided and engaged with the guide portion. Under the action of the guide portion, the movement of the second cover 22 on the groove 10 is guided, thereby improving the stability of the groove cover 20 when unfolding and folding.
[0038] Optionally, the guide portion is provided with a guide groove. A guide wheel is provided on the second side of the second cover 22, and the guide wheel is movably disposed in the guide groove.
[0039] Optionally, the guide portion is provided with a guide rail. A sliding member is provided on the second side of the second cover 22, and the sliding member is movably disposed on the guide rail.
[0040] In one embodiment, the guide portion is arc-shaped, and the arc-shaped guide portion is recessed towards the bottom of the drying tank 11. In this way, the tank cover 20 can avoid jamming during unfolding and folding, and improve the smoothness of the movement of the tank cover 20 on the tank body 10.
[0041] In one embodiment, two guide portions are provided, respectively located on opposite sides of the groove 10. The two ends of the second side of the second cover 22 correspond to and guide the two guide portions one-to-one. This further improves the stability of the groove cover 20's movement.
[0042] In one embodiment, see Figure 2 The drying device also includes a drive unit 24. The drive unit 24 is connected to the first cover 21 and is used to drive the first cover 21 to rotate around the second side of the first cover 21. In use, the drive unit 24 drives the first cover 21 to rotate around the second side of the first cover 21. During the rotation, the first cover 21 drives the second cover 22 to move on the tank 10, so that the tank cover 20 can be unfolded and folded.
[0043] Further, see Figure 1 and Figure 2The slot cover 20 also includes a rotating shaft 23. The rotating shaft 23 is rotatably mounted on the slot body 10, and the second side of the first cover 21 is fixedly connected to the rotating shaft 23. A driving member 24 is connected to the rotating shaft 23 and is used to drive the rotating shaft 23 to rotate about its own axis. In use, the driving member 24 drives the rotating shaft 23 to rotate about its own axis, thereby causing the first cover 21 to rotate. The first cover 21 then drives the second cover 22 to move on the slot body 10, causing the slot cover 20 to unfold and fold.
[0044] In one embodiment, the driving element 24 is a cylinder, and the power output direction of the cylinder is parallel to the opening and closing direction of the slot cover 20.
[0045] Furthermore, the slot cover 20 also includes a connecting rod. The first end of the connecting rod is fixedly connected to the power output shaft of the cylinder, and the second end of the connecting rod is fixedly connected to the rotating shaft 23. In this way, the linear motion of the cylinder can be converted into rotational motion to drive the first cover 21 to rotate.
[0046] Of course, in other embodiments, the drive element 24 may also be a motor.
