[0002] In the high-temperature manufacturing process of photovoltaic cells, quartz boats are often used to carry and transport the cells. However, the following contradiction exists in actual production: in order to achieve a better diffusion coating effect in the tube furnace, the cells need to be placed at an angle; however, when loading and unloading the cells, the angled cells are prone to jamming and damage. Utility Model Content

[0003] In view of this, the present invention provides a quartz boat kit, an automatic loading and unloading device, and a photovoltaic cell processing equipment, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0004] To achieve the aforementioned objective, a first aspect of this utility model provides a quartz boat kit, wherein the quartz boat kit comprises:

[0005] A quartz boat, the quartz boat being used to support the battery cells;

[0006] A boat support, used to support the quartz boat, has inclined grips and can be in a first state and a second state.

[0007] In the first state, the central axis of the tilted gripper extends horizontally, and the battery can be inserted into the quartz boat in a vertical direction;

[0008] In the second state, the boat support deflects, and the battery cells in the quartz boat tilt accordingly. The central axis of the tilted gripper extends at an angle relative to the horizontal direction and is perpendicular to the battery cells in the quartz boat.

[0009] In the quartz boat kit described above, optionally, the quartz boat extends along the width direction of the boat support, and a plurality of the quartz boats are arranged along the length direction of the boat support.

[0010] In the quartz boat kit described above, optionally, the quartz boat has fixed grips, which are disposed opposite to each other at both ends of the quartz boat and extend along the width direction of the boat support. The fixed grips include a first slot that opens downward along the height direction of the quartz boat.

[0011] The boat support has at least two support frames that extend along its length and are arranged in parallel along its width, with the top of the support frames embedded in the first slot.

[0012] In the quartz boat kit described above, optionally, the bottom of the first slot abuts against the top of the support frame.

[0013] In the quartz boat kit described above, optionally, the support frame is inclined, and the center line of the support frame is parallel to the center axis of the inclined grip of the boat support.

[0014] In the quartz boat kit described above, the support frame may optionally have an upward-opening second slot for accommodating the fixing lugs of the quartz boat.

[0015] In the quartz boat kit described above, optionally, the opening angle of the second slot is 60 degrees.

[0016] To achieve the aforementioned objective, a second aspect of this utility model provides an automatic loading and unloading device for a quartz boat kit as described in any one of the first aspects above, wherein the automatic loading and unloading device includes a boat lifting module and a first transport device, the boat lifting module includes a horizontal lifting part, and the boat lifting module lifts or lowers the tilting lugs of the boat support by the lifting part, thereby lifting or lowering the quartz boat kit.

[0017] To achieve the aforementioned objective, a third aspect of this utility model provides a photovoltaic cell processing equipment, wherein the photovoltaic cell processing equipment includes a main platform, a tubular furnace, a paddle, and the aforementioned automatic loading and unloading device for the quartz boat.

[0018] The quartz boat automatic loading and unloading device is used to load and unload the quartz boat kit placed on the horizontal slide of the main unit;

[0019] The horizontal slide includes a transmission device for conveying the quartz boat kit to the slide position of the main unit;

[0020] The main unit's transport device is used to transport the quartz boat kit to the horizontal paddle via the boat-carrying lugs of the quartz boat kit;

[0021] The paddle is used to transport the quartz boat kit to the tubular furnace for processing.

[0022] In the photovoltaic cell processing equipment described above, optionally, the photovoltaic cell processing equipment processes the cell through the tube furnace. The horizontal lifting part of the quartz boat automatic loading and unloading device of the photovoltaic cell processing equipment is used to gradually and completely support the inclined gripper of the quartz boat kit during the lifting process, so that the inclined gripper gradually rotates from the inclined state to the horizontal state parallel to the lifting part. The quartz boat kit and the cell of the quartz boat kit rotate synchronously with the inclined gripper until the cell of the quartz boat kit rotates to the vertical direction. The first conveying device of the quartz boat automatic loading and unloading device is used to unload the cell when the cell rotates to the vertical direction.

[0023] The lifting part is used to reduce the height of the tilting gripper and the quartz boat kit to which the tilting gripper belongs by lowering its height after the first conveying device has completed loading and unloading the battery cell, until the quartz boat kit gradually lowers its height to the horizontal slide of the main unit. After the quartz boat kit contacts the horizontal slide, the lifting part gradually disengages from the tilting gripper. The quartz boat kit gradually rotates to a horizontal state, and the tilting gripper and the battery cell gradually rotate to a tilted state as the quartz boat kit rotates.

[0024] The transmission device on the horizontal slide is used to send the quartz boat kit into the slide position of the main unit.

[0025] The transport device of the main unit lifts the quartz boat kit through the boat-moving lugs of the quartz boat kit and moves the quartz boat kit onto the paddle;

[0026] The paddle is used to transport the quartz boat kit to the tube furnace for processing.

[0027] The quartz boat kit of this utility model has an inclined gripper on the boat support. When the inclined gripper is lifted from below by the horizontal lifting part, the inclined gripper rotates to a horizontal position, which at the same time drives the quartz boat kit and the battery in it to rotate at an angle, so that the battery rotates to the vertical direction, reducing the occurrence of jamming when loading and unloading the battery.

Detailed Implementation

[0037] Referring to the accompanying drawings and specific embodiments, the structure, composition, features, and advantages of the quartz boat kit, automatic loading and unloading device, and photovoltaic cell processing equipment of this utility model will be described below by way of example. However, all descriptions should not be used to limit this utility model in any way.

[0038] For any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the various drawings, the present invention still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle, and thus these further embodiments according to the present invention should also be considered within the scope of the description herein.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0040] Figure 1 This is a cross-sectional view of one embodiment of the quartz boat kit of this utility model; Figure 2 yes Figure 1 A perspective view of the boat support in the Chinese embodiment; Figure 3 for Figure 1 Cross-sectional view of the quartz boat in the embodiment; Figure 4 for Figure 3 A side view of the quartz boat. (See below for reference.) Figures 1 to 4 This invention describes the implementation method of the quartz boat kit.

[0041] like Figure 1 As shown, the quartz boat kit includes a quartz boat 2, a battery plate 1, and a boat support 7. The quartz boat 2 supports the battery plate 1. The battery plate 1 is placed at an angle within the quartz boat kit. The two dotted lines representing the tilt angle E represent the vertical direction and the extension direction of the battery plate 1, respectively. It can be seen that the battery plate 1 has rotated clockwise by an angle E relative to the vertical direction. It should be noted that "clockwise" only indicates... Figure 1 The cross-sectional view shown indicates the rotation direction of the battery cell 1 relative to the vertical direction. The tilt angle E only represents the angle size under this cross-sectional view and cannot be used as a limitation for the quartz boat kit under other views. Placing the battery cell 1 at an angle allows it to achieve a better diffusion coating effect during processing. The boat support 7 is used to support the quartz boat 2, thereby supporting the battery cell 1. To accommodate the tilted battery cell 1, the boat support 7 has tilted lugs 12, as shown in the figure. The tilted lugs 12 extend along the dashed line B, which represents the central axis of the tilted lugs 12, while the dashed line C represents the horizontal plane used to place the boat support 7, indicating the horizontal direction. The tilt angle D is the angle between the dashed lines B and C, representing the angle between the central axis of the tilted lugs 12 and the horizontal direction, indicating the degree of tilt of the tilted lugs 12. Figure 1 As can be seen, the tilting gripper 12, represented by the dashed line C, has rotated clockwise by an angle D relative to the horizontal direction represented by the dashed line C. This makes the tilt angles E and D equal. At this point, the central axis of the tilting gripper 12 is perpendicular to the battery cell 1, meaning that the angle E of the clockwise rotation of the battery cell 1 relative to the vertical direction is the same as the angle D of the clockwise rotation of the tilting gripper 12 relative to the horizontal direction. The boat support 2 has a first state and a second state. In the first state, the central axis of the tilting gripper 12 extends horizontally, allowing the battery cell 1 to be inserted vertically into the quartz boat 2 without jamming during insertion. In the second state, the boat support 7 deflects, causing the battery cell 1 in the quartz boat 2 to tilt accordingly. The central axis of the tilting gripper 12 extends obliquely relative to the horizontal direction and is perpendicular to the battery cell in the quartz boat. The tilted battery cell 1 allows for a more uniform processing effect during diffusion or coating processes.

[0042] Optionally, such as Figure 2 As shown, the quartz boat 2 extends along the width of the boat support 7. Specifically, the boat support 7 has a long strip structure, and its length direction is defined as the longest extension direction between the two ends of the boat support 7. Figure 2In the design, two fixed seats 8 are positioned at both ends of the boat support along its length, and a long, narrow support frame extends along the length of the boat support. The width of the boat support 7 is perpendicular to its length. Figure 1 In the diagram, the length of the boat support is perpendicular to the plane of the paper, and the width of the boat support is the left-right direction as shown in the figure. Figure 2 In the middle, the fixing seat is set perpendicular to the length direction of the boat support, and the fixing seat is set parallel to the paper surface. The width direction of the boat support is... Figure 2 The left and right directions are shown by arrows in the diagram. The quartz boat 2 extends along the width of the boat support 7, meaning the structure of the quartz boat 2 spans the width of the boat support 7, providing stable support for the quartz boat 2 at both ends. Furthermore, at least one quartz boat 2 is arranged along the length of the boat support 7. This means that multiple quartz boats 2 can be arranged side-by-side along the length of the boat support 7 to support the battery cell 1, and the side-by-side arrangement of at least one quartz boat 2 improves processing efficiency. Further, with... Figure 2 For example, multiple quartz boats 2 can be evenly distributed along the length of the boat support 7, improving the uniformity of the battery cell 1 processing.

[0043] As an optional embodiment, such as Figure 3 As shown, the quartz boat 2 in the quartz boat kit has fixed lugs 3, which are positioned opposite each other at both ends of the quartz boat 2 and extend along the width of the boat support 7, thus more securely fixing the quartz boat 2 to the boat support 7. The fixed lugs 3 can be symmetrically distributed at both ends of the quartz boat 2, or they can be asymmetrically distributed. The cross-sectional shape of the fixed lugs 3 can be circular, square, etc. Fixed lugs 3 can be symmetrically arranged at both ends of the quartz boat 2, such as one at each end, and the two fixed lugs 3 are coaxial. In this case, the shape of the fixed lugs 3 should prevent the quartz boat 2 from rotating freely, including but not limited to slotted round or square shafts. This symmetrical design ensures balanced force distribution on the fixed lugs 3, improving the structural stability of the quartz boat 2 and facilitating installation and disassembly. Alternatively, when the fixed lugs 3 at both ends are not coaxial, or when one end has more than one fixed lug 3, a round shaft can be used. Using a greater number of fixing lugs 3 can further distribute the gravity on the quartz boat 2, improving structural reliability. Furthermore, the fixing lugs 3 can be equipped with a first slot 4 that opens downwards along the height of the quartz boat 2. The downward-facing design of the first slot 4 effectively engages with the boat support 7 at the bottom, ensuring a stable installation of the quartz boat 2. It also secures the boat body when the quartz boat 2 is tilted, reducing slippage.

[0044] The boat support 7 can extend along its length and be provided with at least two support frames 9, which are arranged parallel to each other in the width direction of the boat support 7. In this embodiment, the preferred number of support frames is two. The width of the top of the support frame 9 can be designed to fit the shape and size of the first slot 4, so that the top of the support frame 9 can be firmly embedded in the first slot 4. The quartz boat 2 is set on the top of the support frame 9 through the first slot 4 of the fixing lug 3. In order to facilitate the top of the support frame 9 to be embedded in the first slot 4, thereby fixing the quartz boat 2 more securely, the width of the first slot 4 should be greater than the top of the support frame 9. When the boat support 7 is tilted or the support frame 9 of the boat support 7 is tilted, the first slot 4 will restrict the movement of the quartz boat 2 in the width direction of the boat support 7. At the same time, the first slot 4 facilitates the quick installation and removal of the quartz boat 2, improving the efficiency of use.

[0045] In addition, such as Figure 3 As shown, the quartz boat 2 also includes railings 5 ​​and side plates 6. The railings 5 ​​are arranged along the length of the quartz boat 2, and the two side plates 6 are fixed to both ends of the railings 5. The railings 5 ​​are perpendicular to the battery panel 1 and the side plates 6. The railings 5 ​​and side plates 6 form a robust frame structure for the quartz boat 2, which is simple in structure, easy to manufacture, and provides stable support for the battery panel 1. The design concept of this invention is that the battery panel 1 is placed vertically in the quartz boat 2, and the rotation of the quartz boat 2 causes the battery panel 1 to rotate, achieving either tilting or vertical positioning. In comparison, the scheme of fixing the battery panel 1 tilted within the quartz boat 2 using tilted railings 5 ​​makes the structure of the quartz boat 2 more complex and difficult to process. This solution simplifies the structure of the quartz boat 2, reduces precision requirements, and saves processing costs.

[0046] As an alternative embodiment, to ensure stable installation of the quartz boat 2 on the tilted support frame 9, the top height of the support frame 9 is precisely designed to be within the same plane. Since the top of the support frame 9 is embedded in the first slot 4, and the bottom of the first slot 4 abuts against the top of the support frame 9, the bottom of the first slot 4 and the top of the support frame 9 can be in the same plane. This design restricts the vertical movement of the quartz boat 2 and provides reliable support for the processing of the battery cell 1. Furthermore, the fixing lug 3 of the quartz boat 2 can be horizontal relative to the quartz boat 2. In this case, the bottom of the first slot 4 on the fixing lug 3 is also horizontal relative to the quartz boat 2. Therefore, the installation angle of the quartz boat 2 will be determined by the plane where the top of the support frame 9 of the boat support 7 is located. When the top plane of the support frame 9 is horizontal, the quartz boat 2 is in a horizontal position. Of course, the top of the support frame 9 can also be tilted, causing the quartz boat 2 to also tilt. Therefore, the design that the top of the support frame 9 and the bottom of the first slot 4 are in the same plane makes it easy to control the angle of the quartz boat 2 by adjusting the angle of the support frame 9, thus simplifying the structure of the quartz boat 2.

[0047] As an optional embodiment, such as Figure 1 and Figure 2 As shown, the support frame 9 of the boat support 7 is inclined, with its inclination angle being the same as that of the inclined grab ear 12 of the boat support 7. The support frame 9 can be located on both sides of the boat support 7 in the width direction. Specifically, all the support frames 9 of the boat support 7 are parallel to each other, and the center planes of the support frames 9 are located in the same plane. The dashed line A represents the center line connecting the support frames 9 of the boat support 7, and the angle F between the dashed lines A and C represents the angle between the center line connecting the support frames 9 and the horizontal direction, representing the degree of inclination of the support frame 9. The center line connecting the support frames 9 is parallel to the central axis B of the inclined grab ear 12 of the boat support 7. The center line connecting the support frames 9 can be made parallel to the plane containing the top of the support frame 9, thus the plane containing the top of the support frame 9 is also parallel to the central axis B of the inclined grab ear 12. This design makes the inclination angle F equal to the inclination angle D. Since angle D is equal to angle E, the three angles F, D, and E are equal in size.

[0048] Furthermore, such as Figure 3 As shown, the quartz boat 2 is mounted on the support frame 9 of the boat support 7 via a fixed gripper 3. The central axis B of the inclined gripper 12 of the boat support 7, the central line A of the support frame 9 of the boat support 7, the plane where the top of the support frame 9 is located, and the plane where the bottom of the first slot 4 of the quartz boat 2 is located are all parallel.

[0049] It is known that the central axis B of the inclined gripper 12 is perpendicular to the battery cell 1. Therefore, the central line A of the support frame 9 of the boat support 7 is also perpendicular to the battery cell 1, and the plane containing the top of the support frame 9 and the bottom of the first slot 4 is perpendicular to the battery cell 1.

[0050] Therefore, this embodiment provides an implementation method to make the "central axis B of the tilted gripper 12 perpendicular to the battery cell 1", that is, by setting the support frame 9 of the boat support 7 to be tilted, and making the plane of the top of the support frame 9 parallel to the central axis of the tilted gripper 12 of the boat support 7, this objective is achieved. Since the tilted gripper 12 and the support frame 9 are both internal structures of the boat support 7, it is easier to obtain higher machining accuracy and reduce machining costs.

[0051] As an alternative embodiment, such as Figure 2 As shown, the support frame 9 has an upward-opening second slot 10 for holding the fixing lugs 3 of the quartz boat 2. The shape and size of the second slot 10 allow the fixing lugs 3 to be securely embedded in the support frame 9. Specifically, the second slots 10 on the support frame 9 can be evenly arranged along the length of the support frame 9, and their number and arrangement can be adapted to the number and position of the fixing lugs 3 of the quartz boat 2. Taking a quartz boat 2 as an example, if two fixing lugs 3 are provided at each end (e.g.... Figure 4As shown, the two support frames 9 of the boat support 7 should each include two second slots 10 corresponding to the quartz boat 2, and the spacing between the second slots 10 on each support frame 9 should match the spacing of the fixing lugs 3 located at the same end of the quartz boat 2. This design allows the quartz boat 2 to be quickly aligned during installation, while further improving the stability of the installation. To enhance the flexibility and adaptability of the structure, a set of support frames 9 and quartz boat 2 can be designed, with the support frames 9 and the fixing lugs 3 of the quartz boat 2 fitting well together, facilitating replacement and installation.

[0052] Optionally, the upward-opening second slot 10 may include a bottom surface 16 and two side surfaces 15, which extend upward from the bottom surface 16 and are inclined outward along the length of the support frame 9. Preferably, the included angle between the two side surfaces is 60 degrees, so that the opening angle of the second slot 10 is 60 degrees.

[0053] Figure 5 This is a front view of the lifting module of the quartz boat automatic loading and unloading device of this utility model. Figure 6 for Figure 5 The front view of the lifting part 14 of the middle lifting boat module about to contact the boat support tilting grab.

[0054] This utility model also proposes an automatic loading and unloading device for quartz boats, which is used in the quartz boat kit disclosed in this utility model. The automatic loading and unloading device includes a boat lifting module 13, a first transport device, and the quartz boat kit disclosed in this utility model. Specifically, the first transport device is used for loading and unloading battery cells; in this embodiment, the first transport device can insert the battery cells into the quartz boat vertically. Figure 5 As shown, the boat lifting module 13 includes a horizontal lifting section 14. The boat lifting module 13 raises or lowers the inclined gripper 12 of the boat support 7 through the lifting section 14, thereby raising or lowering the quartz boat kit of this utility model. The lifting section 14 can be disposed on the top of the boat lifting module 13. Figure 6The diagram shows the state where the lifting part 14 is about to contact and lift the tilting gripper 12. After the horizontal lifting part 14 supports the tilting gripper 12 from below, due to the imbalance of forces, the tilting gripper 12 gradually rotates from its tilted state to the same horizontal state as the lifting part 14, with the bottom of the tilting gripper 12 completely supported by the lifting part 14. During this process, the entire quartz boat assembly rotates counterclockwise by the same angle D along with the tilting gripper 12. Angles D, E, and F are equal, ultimately causing the battery cell 1 to change from a tilted position to a vertical position, facilitating the loading and unloading of the battery cell 1 by the first handling device. The quartz boat 2 also changes from a tilted to a horizontal state during this process. This embodiment utilizes the simple action of the lifting part 14 of the boat lifting module 13 to achieve a smooth transition of the quartz boat 2 from a tilted state to a horizontal state, and the transition of the battery cell 1 from a tilted state to a vertical state, providing ideal conditions for the subsequent loading and unloading operations of the first handling device. Compared to tilted loading and unloading of battery cells, vertical loading and unloading of battery cell 1 greatly reduces the chance of battery cell 1 getting stuck, thereby reducing the probability of scratches on battery cell 1 and improving the efficiency of the processing and the yield rate.

[0055] This utility model also proposes a photovoltaic cell processing equipment. The photovoltaic cell processing equipment includes a main frame, a tube furnace, a paddle, and the automatic loading and unloading device for quartz boats disclosed in this utility model.

[0056] The main platform is the core operating platform of the photovoltaic cell processing equipment, capable of supporting, transporting, and loading / unloading quartz boat kits. The main platform is equipped with a horizontal slide table, which carries and moves the quartz boat kits. The horizontal slide table includes a transport device, which can be a belt, roller, or chain conveyor, used to transport the quartz boat kits.

[0057] After the first transport device completes the loading and unloading of battery cell 1, the lifting part 14 of the boat lifting module 13 begins to move downward, and the quartz boat kit is slowly placed onto the horizontal slide. At this point, battery cell 1 in the quartz boat kit returns to its tilted position. The transmission device on the horizontal slide is used to precisely transport the quartz boat kit to the slide position on the main unit.

[0058] The main unit's transport device is used to move the quartz boat kit via the boat-moving gripper 11. The transport device can take the form of a robotic arm, grippers, etc., to ensure a secure temporary clamping or connection to the boat-moving gripper 11, guaranteeing smooth movement of the quartz boat kit during transport until it is moved from the slide position to the horizontal paddle. The central axis of the boat-moving gripper 11 can be horizontal.

[0059] The paddle is a key transport device in photovoltaic cell processing equipment, mainly used to smoothly transport the quartz boat kit to the tube furnace for processing. The surface of the paddle can be coated with an anti-slip coating or have grooves suitable for fixing the quartz boat kit to ensure that the quartz boat kit does not shift or tip over during transport.

[0060] Tube furnaces are used for diffusion or coating processes of photovoltaic cells. They provide a high-temperature environment to meet the processing requirements of photovoltaic cells. The tilted placement of the quartz boat kit within the tube furnace helps improve the uniformity of gas diffusion during processing, thereby optimizing cell performance.

[0061] Furthermore, the photovoltaic cell processing equipment proposed in this utility model processes the cell 1 using a tube furnace. During the photovoltaic cell processing, the main structures of this photovoltaic cell processing equipment perform the following functions:

[0062] Function 1: The horizontal lifting section 14 of the automatic quartz boat loading and unloading device in the photovoltaic cell processing equipment is used to gradually and completely support the inclined gripper 12 of the quartz boat kit during the lifting process, so that the inclined gripper 12 gradually rotates from the inclined state to a horizontal state parallel to the lifting section 14. The quartz boat kit and the solar cell 1 of the quartz boat kit rotate synchronously with the inclined gripper 12 until the solar cell 1 of the quartz boat kit rotates to the vertical direction. Loading and unloading the solar cell 1 in the vertical state can greatly reduce the possibility of the solar cell 1 jamming and improve the yield. The first handling device of the automatic quartz boat loading and unloading device is used to load and unload the solar cell 1 when the solar cell 1 rotates to the vertical direction. It can use a mechanical gripper or a vacuum adsorption device to ensure that the solar cell 1 is not damaged.

[0063] Function II: After the first conveying device completes the loading and unloading of the battery cell 1, the lifting unit 14 lowers its height. This lowering of the lifting unit 14 reduces the height of the tilting gripper 12 and the quartz boat assembly to which the tilting gripper 12 belongs, until the quartz boat assembly gradually lowers to the horizontal slide of the main unit. After the quartz boat assembly contacts the horizontal slide, the lifting unit 14 gradually disengages from the tilting gripper 12, and the quartz boat assembly gradually rotates to a horizontal position. The tilting gripper 12 and the battery cell 1 gradually rotate to a tilted position as the quartz boat assembly rotates. This tilted position is the same as the original tilted position of the battery cell 1 in the quartz boat assembly before the loading and unloading process; that is, the angle between the battery cell 1 and the vertical direction is the tilt angle E. This tilt angle allows the quartz boat assembly to provide optimal diffusion during processing.

[0064] Function III: The implementation of the transmission device on the horizontal slide includes, but is not limited to, belts or rollers. The transmission device is used to smoothly move the quartz boat kit to the slide position. Such a transmission device has good anti-slip and positioning capabilities, ensuring the stability of the quartz boat kit during movement, while preventing the battery cell 1 from being bumped or knocked off due to vibration.

[0065] Function IV: The main unit's transport device lifts the quartz boat assembly via the boat-carrying lugs 11. The transport device can grip the boat-carrying lugs 11 with mechanical claws and automatically adjust the gripping force to ensure the stability of the quartz boat assembly. After lifting, the transport device moves the quartz boat assembly from the slide position to the paddle.

[0066] Function V: The paddle is used to transport the quartz boat kit to the tube furnace for processing. The paddle ensures that the quartz boat kit does not shift position or vibrate during its entry into the tube furnace through smooth transport. After entering the tube furnace, the solar cells 1 in the quartz boat kit can undergo diffusion or coating processing in a high-temperature environment.

[0067] This photovoltaic cell processing equipment utilizes automation to load, unload, adjust, and process the quartz boat kit and the solar cell 1, significantly reducing manual intervention and improving production efficiency. Through the cooperation of the tilting gripper 12 and the lifting part 14, the solar cell 1 is ensured to remain vertical during loading and unloading, reducing the chance of damage due to clips. Simultaneously, this design allows the solar cell 1 to be in a tilted position during processing, resulting in more uniform processing within the tube furnace and improving the yield rate of the solar cell 1.

[0068] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
