Description

Technical Field

[0001] This utility model relates to the field of photovoltaic manufacturing technology, specifically to a carrier and carrier boat used in cross-section passivation process. Background Technology

[0002] In recent years, in mainstream battery technologies such as PERC (Passivated Emitter and Rear Cell), TOPCon (Tunnel Oxide Passivated Contact), and HJT (Heterojunction with Intrinsic Thin-layer), half-cell technology has been widely used to reduce the resistance loss of battery modules, increase output power, improve the shading tolerance of battery modules, enhance the mechanical reliability of battery modules, optimize the design flexibility of battery modules, improve production yield and reduce costs. In half-cell technology, the whole cell is divided into 2-3 pieces or smaller pieces by laser dicing technology. At the same time, the cell will have a new cross-section. The cross-section needs to be passivated before string welding to ensure the conversion efficiency of the cell.

[0003] The existing traditional edge passivation equipment has poor automation compatibility in its cassette structure, cannot be quickly positioned when loaded onto the carrier boat, and has low loading and unloading efficiency. Utility Model Content

[0004] In order to solve the technical problems in the prior art, this utility model proposes a carrier and carrier boat for cross-section passivation process.

[0005] The technical solution adopted in this utility model is:

[0006] This utility model proposes a carrier for a cross-section passivation process. The carrier is a cuboid or near-cuboid structure with a single-sided opening. The battery cells are inserted from the side of the carrier opening. The upper part of the opposite two sides of the carrier is provided with a gripping structure that works with mechanical claws, and the bottom part is provided with a positioning structure that works with the carrier placement position of the carrier boat.

[0007] The carrier includes: a back panel, side panels symmetrically arranged on the left and right edges of the back panel, a sheet pressure plate arranged on the upper edge of the back panel and connected to the left and right side panels, and a lower side panel arranged on the lower edge of the back panel and located between the left and right side panels.

[0008] Furthermore, the positioning structure includes: a positioning groove provided at the bottom of the side plate of the vehicle, and a positioning block on the vehicle boat that cooperates with the positioning groove.

[0009] Furthermore, the sheet plate includes a resilient clamping structure for pressing the solar cells together.

[0010] Sheet pressing plates specifically include:

[0011] The main body of the pressure plate is connected to the side plates at both ends;

[0012] The cell pressure plate is connected to the bottom surface of the pressure plate body and can move up and down;

[0013] Multiple elastic elements are installed on the pressure plate body. The telescopic ends of the elastic elements are located on the bottom surface of the pressure plate body and abut against the battery cell pressure plate. When the battery cell pressure plate presses the battery cell close to the bottom surface of the pressure plate body, it compresses the elastic elements.

[0014] Furthermore, both ends of the sheet pressure plate are equipped with elastic pin structures, which are inserted into the pre-reserved holes on the side plate when the elastic pins of the elastic pin structures extend.

[0015] The resilient pin structure includes:

[0016] Multiple pin bushings are installed in the mounting grooves reserved at the ends of the sheet pressure plate;

[0017] The pin is limited by the pin sleeve and can extend outward along the pin sleeve into the mounting groove or retract into the mounting groove.

[0018] A spring, fitted onto the socket end of the pin, with one end abutting against the step formed on the surface of the pin and the other end abutting against the inner wall of the mounting groove, will cause the pin to extend out of the mounting groove.

[0019] Pull plate, which connects two parallel pins. When the pull plate is pressed, the pins are retracted into the mounting slot.

[0020] Furthermore, a sheet tray for stacking battery cells is placed on the lower side plate, and a clearance notch is reserved on the lower side plate for picking up or placing the sheet tray.

[0021] Furthermore, the back panel has multiple sets of separator fixing holes corresponding to different sizes of battery cells.

[0022] Furthermore, the side of the vehicle facing away from the opening has multiple locking points for securing the surveillance footage.

[0023] This utility model also proposes a vehicle boat, which includes the aforementioned vehicle, with the sides of the vehicle openings located on both sides of the vehicle boat arranged opposite each other.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The single-sided opening design on the side enables precise exposure of the cross-section during the sidewall passivation process. Combined with the physical limiting function of the positioning structure, it ensures that the carrier maintains a stable posture throughout the cross-section passivation process. At the same time, the mechanical gripper adapter structure can be adapted to existing automated transmission equipment, improving production efficiency.

[0026] 2. By adding an elastic clamping structure and a clamping structure to the sheet pressure plate, the design can be simplified, space can be saved, and the sheet loading capacity can be increased. In practice, the half-sheet loading capacity can be at least 1,000 sheets.

[0027] 3. Design a sheet pallet so that, during automated sheet loading, the sheets are neatly stacked on the pallet before being inserted into the lower side plate of the carrier. When handling the pallet, the automated equipment can control the robotic arm to vibrate slightly, ensuring a tight, gap-free fit during sheet insertion. Simultaneously, the sheet clamping plate presses the sheet firmly after insertion, ensuring no gaps between the upper and lower surfaces and preventing slippage.

[0028] 4. Several sets of pre-drilled threaded holes for fixing partitions to different sizes of sheets are reserved on the back plate. When the sheet size needs to be changed, the internal space can be modified by adding an inner partition, thereby achieving compatibility with different sizes of sheets. Attached Figure Description

[0052] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0053] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0054] The existing traditional edge passivation equipment has poor automation compatibility in its cassette structure, cannot be quickly positioned when loaded onto the carrier boat, and has low loading and unloading efficiency.

[0055] In this regard, such as Figure 1As shown, an embodiment of this utility model proposes a carrier for cross-section passivation process. The carrier 1 can be made of aluminum and has an overall structure of a cuboid or near-cuboid with a single-sided opening (such as chamfered edges). The battery cell is inserted from the front side of the opening of the carrier 1, so that the battery cell can enter and exit from one side of the opening direction. At the same time, the other closed sides prevent the battery cell from being coated around the non-cross-section surfaces.

[0056] The carrier 1 includes a clamping structure 121 and a positioning structure 122. The clamping structure 121 is located on the upper part of opposite sides of the carrier 1, and its structural design matches the clamping end of the mechanical gripper, ensuring that the mechanical gripper can stably clamp the carrier 1 for transportation or positioning. The positioning structure 122 is located at the bottom of the carrier 1 corresponding to the placement position of the carrier boat 2. Its shape is adapted to the positioning block on the carrier boat 2. The positioning and fixing of the carrier 1 on the carrier boat 2 is achieved through the cooperation of the positioning block and the positioning structure 122.

[0057] The positioning structure 122 is located on the bottom of opposite sides of the carrier 1, specifically as a protrusion or groove structure that matches the positioning block of the carrier boat 2. This structure achieves the positioning of the carrier 1 through physical cooperation with the positioning block of the carrier boat 2, ensuring that the position of the carrier 1 remains stable during the process and avoiding uneven heating of the battery cells or abnormal passivation effect due to displacement.

[0058] The carrier 1 achieves both mechanical automated gripping and positioning functions through the cooperation of the gripping structure 121 and the positioning structure 122. Its single-sided opening design not only meets the requirements for loading and unloading battery cells but also reduces structural redundancy. Combined with the physical limiting function of the positioning structure 122, it ensures that the carrier 1 maintains a stable posture throughout the cross-section passivation process. At the same time, the mechanical gripper adapter structure can be adapted to existing automated transmission equipment, improving production efficiency.

[0059] like Figure 2 As shown, the main frame of the carrier 1 includes: a back plate 11, two side plates 12, a sheet pressure plate 13, and a lower side plate 14. Specifically, the back plate 11 serves as the main support structure of the carrier 1, and its dimensions match the placement area of ​​the solar cells. The side plates 12 are symmetrically and vertically installed on the left and right edges of the back plate 11, extending upwards to form lateral support for the carrier 1 and confining the solar cells on the left and right sides within the carrier 1. The sheet pressure plate 13 is fixed to the upper edge of the back plate 11 and connected to the top of the left and right side plates 12. By pressing against the upper part of the stacked solar cells within the carrier 1, it restricts the vertical movement of the solar cells, ensuring that the solar cells are fixed in position within the carrier 1.

[0060] The lower side panel 14 is vertically disposed on the lower edge of the back panel 11 and is embedded between the left and right side panels 12.

[0061] The components of carrier 1 are assembled to form a front-opening bearing cavity. The back plate 11, side plate 12, and sheet pressure plate 13 together constitute the fixing frame for the battery cells. The lower side plate 14 cooperates with the positioning structure 122 to ensure the stable installation of carrier 1 on carrier boat 2. This structural design not only ensures the positioning of the battery cells in the cross-section passivation process, but also simplifies the maintenance and cleaning of carrier 1 through modular assembly.

[0062] The positioning structure 122 specifically includes a positioning groove, which is located at the bottom of the side plates 12 on both sides of the vehicle 1. The positioning groove is a trapezoidal groove structure, and its depth and width match the size of the positioning block on the vehicle boat 2.

[0063] When carrier 1 is placed in the placement position of carrier boat 2, the positioning block is embedded inside the positioning groove, and the carrier 1 is positioned in the lateral direction through lateral physical restraint. This lateral positioning method, together with other positioning structures at the bottom of carrier 1, forms a multi-point synergistic effect, effectively eliminating the possible front-to-back or left-to-right offset of carrier 1 during the process, ensuring the uniformity of heat distribution to the battery cells, and at the same time, by setting the positioning structure on the side, the occupancy of the positioning structure on the internal space of the carrier is reduced.

[0064] Preferably, the edge of the positioning groove can be chamfered, which facilitates quick and accurate alignment of the carrier 1 and avoids wear caused by direct collision of metal parts. This design, through the cooperation between the positioning groove at the bottom of the side plate 12 and the positioning block of the carrier boat 2, significantly improves the alignment efficiency during the installation of the carrier 1, while reducing the risk of errors caused by manual adjustment.

[0065] Specifically, the bottom surface of the sheet pressure plate 13 is provided with an elastic clamping structure for clamping the battery cells. The elastic clamping structure achieves flexible clamping of the battery cells through the split design of the sheet pressure plate 13. A preferred embodiment is as follows:

[0066] like Figure 3 As shown, the sheet pressure plate 13 includes: a cover plate 130, a pressure plate body 131, a battery cell pressure plate 132, and an elastic element 133. The pressure plate body 131 serves as the load-bearing frame of the elastic pressing structure, and its two ends are connected to the top of the side plate 12 by bolts, buckles, or elastic pins to form a lateral positioning reference.

[0067] The cell pressing plate 132 is movably connected to the bottom surface of the pressing plate body 131 via a pin 134, allowing it to move slightly in the vertical direction. The elastic element 133 is implemented using a spring plunger. Specifically, multiple circular mounting grooves are opened on the bottom surface of the pressing plate body 131, and the spring plunger is fixed in the circular mounting grooves by threads. The spring ball at its bottom directly contacts the cell pressing plate 132. When the cell is placed in the carrier 1, the cell pressing plate 132 is slightly pushed down by the upper surface of the cell, moving downward and compressing the spring 137 inside the spring plunger. At this time, the spring ball applies pressure evenly through elastic reaction force, so that the cell pressing plate 132 always maintains a soft contact with the surface of the cell.

[0068] The spring's cushioning properties ensure stable clamping of the solar cells while preventing surface damage due to excessive pressure. The modular structure of the spring plunger facilitates quick replacement of the elastic elements during maintenance, and the multi-point distribution of the elastic elements 133 ensures uniform clamping force, preventing localized deformation or displacement of the solar cells during the manufacturing process.

[0069] In a specific embodiment, both ends of the sheet pressure plate 13 are equipped with resilient pin structures. The automatic positioning function of the resilient pin structures simplifies the installation and replacement process of the sheet pressure plate 13, allowing operation to be completed without additional tools, while ensuring the stability of the connection points and facilitating quick component replacement during process maintenance.

[0070] The resilient pin structure includes: a pin sleeve 135, a pin 136, a spring 137, and a pull plate 138. The pin sleeve 135 is pre-embedded in the mounting groove at the end of the sheet pressure plate 13, serving as a guide and limiting reference for the movement of the pin 136. The pin 136 slides axially along the sleeve, with one end extending outside the mounting groove to form a insertion end, and the other end having a stepped structure and connecting to the sleeve end. The spring 137 is sleeved outside the sleeve end of the pin 136, with one end in close contact with the pin step and the other end pressing against the inner wall of the mounting groove. Through a pre-compression state, it continuously applies an outward pushing force to the pin 136, keeping the pin 136 in a locked state, extending out of the mounting groove. The pull plate 138 is laterally fixed between the sleeve ends of the two parallel pins 136. When it is necessary to release the locking of the pins 136, the operator presses the pull plate 138, simultaneously causing all the pins 136 to retract into the mounting groove against the resistance of the spring 137, completing a quick unlocking process.

[0071] By using the pull plate 138, the operation of multiple pins 136 is simplified to single-point control, which not only ensures connection reliability but also improves the efficiency of sheet plate assembly and disassembly. The collaborative work of multiple components enables the carrier 1 to achieve instantaneous locking and releasing of pins 136 in automated handling, while avoiding the operational complexity caused by traditional threaded fastening or snap-fit ​​structures.

[0072] Specifically, the cover plate 130 is a dustproof cover plate, which covers and is installed on the upper surface of the pressure plate body 131. It can block the mounting groove on the pressure plate body 131 to prevent dust from entering the pressure plate body 131 and causing malfunction. At the same time, the two ends of the cover plate 130 are provided with clearance notches to avoid the pressing movement space of the pull plate 138, so that the pull plate 138 can be pressed and used normally.

[0073] In specific embodiments, such as Figure 5 As shown, a sheet tray 15 is provided on the lower side plate 14 as a stacking support platform for the battery cells. Its surface is flat and parallel to the opening side of the back plate 11. The sheet tray 15 can be placed on top of the lower side plate 14. The clearance notch of the lower side plate 14 is located in its edge area near the opening side, forming a laterally extending notch space. This notch penetrates the side wall of the lower side plate 14, providing an operating channel for the gripping end of an automated robot or automated pallet. At the same time, the sheet tray 15 has positioning holes for easy handling and support. When it is necessary to pick up or put down the sheet tray 15, the clamp is inserted from the opening side of the carrier 1, passes through the clearance notch, and accurately holds the bottom of the sheet tray 15, realizing non-contact (non-contact with the battery cells) loading and unloading of the sheet tray 15.

[0074] By reserving structured space, the loading and unloading of the sheet tray 15 can be performed without disassembling the main body of the carrier 1, significantly improving the efficiency and safety of batch processing of solar cells in the cross-section passivation process. Moreover, during cell insertion, the sheet tray 15 can be slightly shaken by an automated robotic arm to expel residual air between the solar cells, ensuring tight adhesion and reducing plating smearing.

[0075] In specific embodiments, such as Figure 4 As shown, the backplate 11 has multiple sets of pre-drilled separator fixing holes (not shown in the figure). These holes are arranged in a matrix and cover different spacing specifications. The separators 17 are fixed to the corresponding holes by bolts or snap-fit ​​components, forming adjustable cell positioning zones. When it is necessary to be compatible with silicon wafers of different sizes, the position of the separators 17 can be readjusted according to the actual size of the cells: by removing the original separators and installing them into the new hole combination, a bearing area matching the shape of the cells can be defined. At the same time, the cell pressure plate 132 and the sheet support plate 15 provide standardized adaptation versions, whose length and width parameters are directly related to the separator layout. When replacing, only the original pressure plate and support plate need to be disassembled and replaced with new components of the corresponding specifications. With the adjustment of the separator hole positions, the size change of the carrier 1 can be quickly completed. This modular design allows the carrier 1 to adapt to the process requirements of different sized cells without the need for overall replacement, reducing equipment maintenance costs and improving production line flexibility.

[0076] In specific embodiments, such as Figures 6 to 11As shown, the edge area of ​​the side of the carrier 1 facing away from the opening has multiple locking slots. The slots are arranged linearly or in an array. The locking points 16 are installed in the slots by snap-fit ​​or threaded connection. After the locking points 16 are installed, the edge of the monitoring film can be clamped, which is the locking point surface B. When placing the monitoring film, it is placed in the center area of ​​the bearing surface of the carrier 1, and then the locking points 16 are embedded into the corresponding slots to achieve stable clamping of the monitoring film.

[0077] At least one checkpoint 16 should be configured on each side of the monitoring area.

[0078] There are four specific implementation methods, such as... Figure 6 , 7 As shown, two locking points 16 are set on the left and right sides near the edges, and two locking points 16 are set on the bottom edge.

[0079] like Figure 8 As shown, only one checkpoint 16 is configured on each side of the monitoring area.

[0080] like Figure 9 As shown, two locking points 16 are set on the left and right sides near the edges, and one locking point 16 is set on the bottom edge.

[0081] like Figure 10 As shown, two locking points 16 are set near the edges on the left and right sides, one locking point 16 is set at the bottom edge, and one locking point 16 is set at the top edge, for a total of 4 locking points.

[0082] As a carrier for process parameter detection, the monitoring chip, after passivation coating is completed, can accurately assess the stability of the current process conditions by analyzing key indicators such as the uniformity and thickness distribution of the passivation film on its surface. The integrated monitoring chip directly embeds quality inspection into the production process, eliminating the need for additional sampling or process interruption, significantly improving quality control efficiency and data accuracy. Therefore, based on the passivation film performance characteristics obtained from the monitoring, the carrier 1, passivation boat, or process of this application can be specifically improved to enhance the passivation coating quality.

[0083] Specifically, such as Figure 11 As shown, in the carrier boat 2 (or passivation boat) proposed in this application, the passivation surfaces A (i.e., the sides of the openings) of the two carriers 1 are arranged opposite each other, and an electrode assembly is provided in the middle. When it is necessary to measure the passivation film performance characteristics at a certain position of the carrier 1 of the passivation boat, the passivation surfaces A of one or more carriers 1 of the passivation boat can be swapped with the locking surfaces B, so that the locking surfaces B of the carrier 1 face the middle electrode assembly, and the monitoring sheet is locked on the locking surfaces B, thereby realizing the passivation coating of the monitoring sheet set on the locking surfaces B of the carrier 1.
