Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to a passivated contact battery cell boat fixing device and a transport mechanism. Background Art

[0002] Passivated contact cells are a type of solar cell technology based on the principle of selective carriers, offering a simple manufacturing process and high reliability. The production process of passivated contact cells on an assembly line involves diffusion, oxidation, and annealing. Before processing, the cells are loaded into a boat using a robot. The boat is then transported to the processing equipment for processing. After processing, the cells are placed in a basket.

[0003] However, after the battery cell process is completed, the battery cells will cause edge chipping and breakage when entering and exiting the battery cell boat. The battery cells in the battery cell boat will collide with the slots where the battery cells are placed in the battery cell boat, causing edge chipping and breakage, resulting in continuous fragments, which will affect the quality of the battery cells. The quality of the battery cells will in turn affect the production efficiency of the battery cells. Utility Model Content

[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] In this application, terms such as "upper," "lower," "left," "right," "top," "bottom," "inner," "outer," "vertical," and "horizontal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0050] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to express a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0051] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0052] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0053] The production process of passivated contact cells is a complex and sophisticated process, mainly involving multiple steps, such as: silicon wafer pretreatment, tunnel oxide layer formation, doped amorphous silicon layer deposition, annealing treatment and subsequent processing. Before the passivated contact cells are processed, they are moved to a cell boat by a robot, and then the cell boat is sent into the furnace of the process equipment for processing. After the passivated contact cells are processed, the cells in the cell boat are sent to the basket, and the cell basket is loaded with cells for cleaning, etching, coating and other process steps. However, before the cells in the cell boat are sent to the basket, the cells will shake in the cell boat, causing the cells to break and fragment, resulting in continuous fragments. This increases the defective rate and fragmentation rate of cell production, and reduces the efficiency of actual passivated contact cell production.

[0054] Based on this, the present application discloses a passivated contact cell boat fixing device. The cell boat placed on the boat support module is positioned by the boat positioning module to fix the cell boat. The auxiliary tooth support module fixes the cell in the cell boat, which can prevent the cell from shaking or colliding in the cell boat during the movement of the entire device, causing edge collapse and breakage.

[0055] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0056] See also Figure 1 , Figure 1The structure of the passivated contact cell boat fixture 100 disclosed in an embodiment of the present application is schematically illustrated. In a first aspect, the present application discloses a passivated contact cell boat fixture 100. The passivated contact cell boat fixture 100 is used in a transport mechanism that drives the cell boat within a process equipment furnace. Specifically, the passivated contact cell boat fixture 100 comprises a base plate 1, a secondary tooth support module 2, a boat support module 3, and a boat positioning module 4. The boat support module 3 is mounted on the base plate 1 and supports the cell boat. The boat support module 3 can be switched relative to the base plate 1 between a positioning position and a loading and unloading position. The boat positioning module 4 is mounted on the base plate 1. When the boat support module 3 is in the positioning position, the boat positioning module 4 surrounds the boat support module 3 and is used to position the cell boat to secure the cell boat. The secondary tooth support module 2 is mounted on the boat support module 3 and, when the boat support module 3 is in the positioning position, is used to secure the cells within the cell boat. That is to say, the boat support module 3 of the passivated contact battery boat fixing device 100 is used to support the battery boat. When the battery boat is placed on the boat support module 3, the boat positioning module 4 positions the battery boat so that the battery boat is fixed, and the auxiliary tooth support module 2 fixes the battery cells in the battery boat placed on the boat support module 3.

[0057] Among them, when the boat support module 3 is located at the positioning station, the passivation contact cell boat fixing device 100 fixes the cell boat; when the boat support module 3 is located at the loading and unloading station, the cell boat placed in the passivation contact cell boat fixing device 100 is taken and placed.

[0058] In this way, when the boat support module 3 of the passivation contact cell boat fixing device 100 is located in the positioning module, the cell boat is placed on the boat support module 3, and then the cell boat on the boat support module 3 is positioned by the boat positioning module 4, which can accurately fix the cell boat in the predetermined position, ensure the stability of the cell boat during the processing, avoid processing errors caused by position offset, and improve the quality of the cell. The design of the auxiliary tooth support module 2 solves the problem of fixing the cell in the cell boat during the processing. It not only effectively prevents the cell from shaking and displacing in the cell boat during transportation or processing, but also reduces direct contact between cell cells, reduces the risk of damage caused by friction or collision, protects the integrity of the cell, reduces the situation of cell edge collapse and breakage, and reduces the defective rate of the cell.

[0059] Further, if Figure 1As shown, the auxiliary tooth support module 2 includes an auxiliary tooth support member 21, which is arranged on the boat support module 3. When the boat support module 3 is located at the positioning station, the auxiliary tooth support member 21 is arranged corresponding to the battery cell boat in the vertical direction. A plurality of auxiliary teeth 211 are provided on the auxiliary tooth support member 21. A battery cell is fixed between two adjacent auxiliary teeth 211, and the gap between two adjacent auxiliary teeth 211 gradually decreases along the support surface perpendicular to the boat support module 3 and pointing to the auxiliary tooth support member 21.

[0060] Among them, such as Figure 1 As shown, the direction perpendicular to the support surface of the boat support module 3 and pointing to the auxiliary tooth support 21 is the vertically downward direction, that is, the gap between two adjacent auxiliary teeth 211 gradually decreases along the direction perpendicular to the support surface of the boat support module 3 and pointing to the auxiliary tooth support 21, so that the gap between two adjacent auxiliary teeth 211 gradually decreases from top to bottom along the vertically downward direction.

[0061] In this way, the auxiliary tooth support 21 is provided on the boat support module 3. When the boat support module 3 is located at the positioning station, the auxiliary tooth support 21 can accurately correspond to the battery boat in the vertical direction, ensuring the stable support of the battery boat to a certain extent. The gap between two adjacent auxiliary teeth 211 gradually decreases along the direction perpendicular to the support surface of the boat support module 3 and pointing to the auxiliary tooth support 21, ensuring that the battery cell can be stably and accurately placed in the predetermined position. The auxiliary tooth support 21 can significantly improve the positioning accuracy of the battery cell in the battery cell boat, so that the battery cell in the battery cell boat can remain stable on the auxiliary tooth support module 2, and is not prone to offset or shaking, thereby ensuring the reliability of the battery cell during the entire processing process and reducing the error and scrap rate caused by inaccurate positioning of the battery cell.

[0062] Optionally, the material of the auxiliary teeth 211 is a flexible material, that is, the auxiliary teeth 211 that are in contact with the battery cells are made of flexible material. In this way, the auxiliary teeth 211 made of flexible material can achieve soft contact of the battery cells on the auxiliary tooth support 21, provide better cushioning, reduce the risk of battery cell damage due to mechanical shock or vibration, and reduce the chance of battery cell fragments. At the same time, the auxiliary teeth 211 made of flexible material can better fit the battery cells, improving the stability and reliability of fixing the battery cells. In addition, the flexible material is less likely to produce scratches or indentations on the surface of the battery cell during the process of fixing the battery cell, which helps to protect the appearance quality of the battery cell. The auxiliary teeth 211 made of flexible material can reduce friction and wear between the battery cell and the battery cell during long-term use, thereby extending the service life of the auxiliary tooth support 21 and the battery cell.

[0063] Combine Figure 1 and Figure 2 , Figure 2This is a bottom schematic diagram of the passivated contact cell boat fixing device 100 disclosed in an embodiment of the present application. Furthermore, the auxiliary tooth support module 2 also includes a first drive component 22, which is connected to the auxiliary tooth support member 21. When the boat support module 3 is in the positioning position, the first drive component 22 drives the auxiliary tooth support member 21 to move vertically. In other words, the first drive component 22 of the auxiliary tooth support module 2 is connected to the auxiliary tooth support member 21, and the first drive component 22 drives the auxiliary tooth support member 21 to rise vertically, securing the cell between the upper end of the cell boat and the auxiliary tooth support member 21. In this way, the first drive component 22 can precisely control the movement distance and speed of the auxiliary tooth support member 21, ensuring that the auxiliary tooth support member 21 reaches the predetermined vertical position. Simultaneously, the first drive component 22 drives the auxiliary tooth support member 21 to rise vertically, providing better support and fixation for the cell within the cell boat, further preventing the cell from swaying within the cell boat and colliding with the cell boat, resulting in edge chipping and damage.

[0064] In some embodiments, see Figure 1 and Figure 2 The auxiliary tooth support module 2 further includes a fixed plate 23 and an adjustment plate 24. The fixed plate 23 is connected to the boat support module 3. The first drive component 22 includes a driving end and a fixed end. The fixed end is fixedly connected to the fixed plate 23, and the driving end is connected to the auxiliary tooth support member 21 via the adjustment plate 24. The adjustment plate 24 has a first through hole 24a. The auxiliary tooth support member 21 and the adjustment plate 24 are connected through the first through hole 24a. The first through hole 24a has a first predetermined length L1, which allows the auxiliary tooth support member 21 to be adjusted along the first horizontal direction X. The first horizontal direction X is the direction in which the battery cells are arranged within the battery cell boat. In other words, the auxiliary tooth support member 21 is connected to the boat support module 3 via the first drive component 22. The auxiliary tooth support member 21 is connected to the driving end of the first drive component 22 via the adjustment plate 24, and the auxiliary tooth support member 21 is connected to the adjustment plate 24 via the first through hole 24a. Specifically, a threaded hole is formed at the bottom of the auxiliary tooth support 21, and a screw is passed through the first through hole 24a and the threaded hole. Tightening the screw connects the auxiliary tooth support 21 to the adjustment plate 24. Furthermore, the first through hole 24a has a first preset length L1, allowing the screw to be adjusted within this length. In other words, the first preset length L1 provides the auxiliary tooth support 21 with a movable space for adjustment along the first horizontal direction X. The first horizontal direction X is the direction in which the battery cells are arranged in the battery cell boat, i.e., from right to left.

[0065] Thus, the first through-hole 24a on the adjustment plate 24 is designed with a first predetermined length L1. This design allows the auxiliary tooth support member 21 to be adjusted along the first horizontal direction X (i.e., the direction in which the cells are arranged within the cell boat). This ensures that the auxiliary tooth support member 21 can adapt to cells of different sizes or arrangements, improving the compatibility and flexibility of the device. Simultaneously, the fixing plate 23 is connected to the boat support module 3. This connection provides a solid foundation for the entire auxiliary tooth support module 2, enabling the auxiliary tooth support member 21 to stably support and secure the cells within the cell boat.

[0066] Alternatively, as Figure 1 As shown, the support surface of the boat support module 3 for supporting the cell boat is inclined along the first horizontal direction X. In other words, when the cell boat is placed on the boat support module 3, the support surface of the boat support module 3 that contacts the cell boat is inclined along the first horizontal direction X, the cell boat is tilted along the first horizontal direction X, and the cell boat is positioned tilted along the first horizontal direction X. The cell boat is secured within the cell boat by the auxiliary tooth support members 21. Thus, when the boat support module 3 is in the positioning station, the cell boat is placed on the cell boat, tilted along the first horizontal direction X, and the auxiliary tooth support members 21 secure the cell boats, positioning them vertically within the cell boat. At this point, the right side of the slot where the cell boat is placed at the upper end of the cell boat presses against the cell boat, securing the upper portion of the cell boat. The auxiliary tooth support members 21 secure the lower portion of the cell boat, further securing the cell boat within the cell boat and preventing the cell boats from shaking within the cell boat, which could cause edge breakage or damage.

[0067] Further, see Figure 3 and Figure 4 , Figure 3 This is a top view of the passivated contact cell boat fixing device 100 disclosed in an embodiment of the present application. Figure 4This is a side view of the passivated contact cell boat fixing device 100 disclosed in an embodiment of the present application. The boat support module 3 includes a first boat support member 31 and a second boat support member 32. The first boat support member 31 and the second boat support member 32 are located on either side of the auxiliary tooth support module 2. The first boat support member 31 includes a first support surface 31a, and the second boat support member 32 includes a second support surface 32a. The first support surface 31a and the second support surface 32a are both inclined and located on the same surface. In other words, when the cell boat is placed on the boat support module 3, the cell boat is actually placed on the first boat support member 31 and the second boat support member 32. The first support surface 31a and the second support surface 32a of the first boat support member 31 and the second boat support member 32, which contact the cell boat, are both inclined along the first horizontal direction X and are located on the same surface after being inclined, with no height difference. In this way, the inclined setting of the first support surface 31a and the second support surface 32a can better adapt to the arrangement of the battery cells, help provide more stable and uniform support for the battery cells in the battery cell boat, and reduce the risk of battery cell displacement or damage due to insufficient support. In addition, the inclined support surface also has a certain guiding effect, which can prompt the battery cells to automatically arrange neatly in the boat. The two support surfaces are located on the same surface, which ensures the positioning accuracy of the battery cells in the battery cell boat. The inclined support surfaces located on the same surface help the battery cells maintain a consistent position during transportation and processing. The inclined design of the first support surface 31a and the second support surface 32a combined with the auxiliary tooth support 21 can further fix the battery cells in the battery cell boat, preventing them from shaking in the battery cell boat and colliding with the battery cell boat to cause edge collapse and damage.

[0068] In some embodiments, as Figure 1 As shown, the boat positioning module 4 includes a first positioning assembly 41, which is disposed on the base plate 1 and is used to secure the cell boat along the first horizontal direction X. That is, supported by the boat support module 3, the first positioning assembly 41 positions the cell boat in the first horizontal direction X, securing the cell boat in the first horizontal direction X. In this way, the first positioning assembly 41 ensures the precise fixation of the cell boat in the first horizontal direction X. Through the securing action of the first positioning assembly 41, the position of the cell boat on the production line is further stabilized. This helps reduce cell damage and process errors caused by cell boat sway or positional changes, thereby improving cell production efficiency and product qualification rate.

[0069] Further, combined with Figure 1 and Figure 3The first positioning assembly 41 includes a first limiting plate 411 and a boat-side positioning cylinder 412. The first limiting plate 411 is disposed on the boat support module 3, and the boat-side positioning cylinder 412 is disposed on the base plate 1. The boat-side positioning cylinder 412 includes a movable end and a fixed end. The fixed end of the boat-side positioning cylinder 412 is fixedly connected to the base plate 1. The battery boat includes a first end face and a second end face that are disposed opposite each other along a first horizontal direction X. The first limiting plate 411 is configured to abut against the first end face of the battery boat, and the boat-side positioning cylinder 412 is configured to abut against the second end face of the battery boat. In other words, the first end face of the battery boat along the first horizontal direction X abuts against the first limiting plate 411. When the battery boat is placed on the boat support module 3, the first limiting plate 411 limits the first end face of the battery boat along the first horizontal direction X, while the movable end of the boat-side positioning cylinder 412 moves to limit the second end face of the battery boat, thereby securing the battery boat in the first horizontal direction X. In this way, the first limit plate 411 abuts the first end surface of the cell boat, providing initial and stable positioning. The movable end of the boat-side positioning cylinder 412 abuts the second end surface of the cell boat, achieving further positioning adjustment. The first limit plate 411 and the boat-side positioning cylinder 412 abut from both ends of the cell boat, forming a stable clamping effect. In addition, by adjusting the stroke and force of the cylinder, the cell boat can be positioned to meet different process requirements.

[0070] In some embodiments, combined Figure 1 and Figure 3 The boat positioning module 4 also includes a second positioning component 42, which is provided on the base plate 1. The second positioning component 42 is used to fix the battery boat along the second horizontal direction Y. The second horizontal direction Y is perpendicular to the first horizontal direction X. In this way, the first positioning component 41 has positioned the battery boat along the first horizontal direction X, and the second positioning component 42 is further fixed in the second horizontal direction Y, ensuring the precise positioning of the battery boat in the plane and reducing the process error caused by position offset. It also enhances the stability of the battery boat during processing and reduces displacement or tilting caused by vibration or external force. During the movement in the furnace of the process equipment, the battery boat may be affected by various forces and shake. The second positioning component 42 helps to reduce this shaking and ensure that the battery boat remains stable during processing.

[0071] Further, if Figures 1 to 4As shown, the second positioning assembly 42 includes a second limiting plate 421 and a plurality of positioning cylinders 422. The second limiting plate 421 is disposed on the boat support module 3, and the plurality of positioning cylinders 422 are spaced apart on the base plate 1 along the first horizontal direction X. The battery boat includes a third end face and a fourth end face disposed opposite each other along the second horizontal direction Y. The second limiting plate 421 is configured to abut the third end face of the battery boat, and the plurality of positioning cylinders 422 are configured to abut the fourth end face of the battery boat. In other words, the second limiting plate 421 abuts the third end face of the battery boat, and the positioning cylinders 422 abut the fourth end face of the battery boat, thereby securing the battery boat in the second horizontal direction Y.

[0072] In this way, the second limiting plate 421 abuts the third end face of the battery boat, providing stable support and positioning for one end of the battery boat in the second horizontal direction Y. Multiple positioning cylinders 422 are spaced apart along the first horizontal direction X and abut against the fourth end face of the battery boat, achieving uniform support and precise fixation at the other end in the Y direction. When the positioning cylinder 422 pushes the fourth end face of the battery boat, the third end face of the battery boat abuts the second limiting plate 421. The second limiting plate 421 and the positioning cylinder 422 work together to provide dual positioning for the battery boat in the second horizontal direction Y, enhancing the stability of the battery boat in the second horizontal direction Y during processing. The multiple positioning cylinders 422 are spaced apart along the first horizontal direction X to ensure uniform force on the battery boat in the second horizontal direction Y, preventing deformation or damage to the fourth end face of the battery boat due to uneven force at a single point.

[0073] Optionally, combined Figure 1 and Figure 3The second positioning assembly 42 further includes a plurality of connecting brackets 423 , which are arranged corresponding to the positioning cylinders 422 . One positioning cylinder 422 is connected to the base plate 1 via one connecting bracket 423 . The connecting bracket 423 is provided with a second through-hole 423a . The connecting bracket 423 and the base plate 1 are connected via the second through-hole 423a . The second through-hole 423a has a second preset length, so that the connecting bracket 423 can be adjusted along the second horizontal direction Y. In other words, the positioning cylinder 422 is mounted on the connecting bracket 423 , and the connecting bracket 423 is connected to the base plate 1 via the second through-hole 423a . That is, the base plate 1 is provided with a threaded hole, and a screw is used to penetrate the second through-hole 423a and the threaded hole, so that the connecting bracket 423 is mounted on the base plate 1 . The second preset length of the second through-hole 423a enables the connecting bracket to be adjusted along the second horizontal direction Y. Thus, on the one hand, the second through hole 423a provided on the connecting frame 423 has a second preset length, which allows the connecting frame 423 to be adjusted to a certain extent along the second horizontal direction Y on the base plate 1. By adjusting the position of the connecting frame 423 on the base plate 1, the relative position of the positioning cylinder 422 can be changed. At the same time, the connecting frame 423 serves as a connecting bridge between the positioning cylinder 422 and the base plate 1, which can ensure that when the positioning cylinder 422 is working, the connecting frame 423 can withstand the corresponding force and torque, thereby maintaining the stability and reliability of the connection. On the other hand, when the positioning cylinder 422 or the connecting frame 423 fails or needs to be replaced, the connecting frame 423 and the base plate 1 are connected in a detachable manner, so maintenance and replacement can be conveniently performed.

[0074] In some embodiments, combined Figure 1 and Figure 3 The second positioning assembly 42 further includes a shaping module 424. The shaping module 424 is disposed on the boat support module 3. The shaping module 424 is capable of moving along the second horizontal direction Y to push the battery cells in the battery boat. In other words, the shaping module 424 is capable of moving along the second horizontal direction Y to contact the battery cells in the battery boat and push the battery cells in the battery boat. In this way, the shaping module 424 can accurately position and shape the battery cells to ensure that the battery cells are neatly arranged in the battery boat. This is more important for the subsequent entry and exit of the battery cells in the battery boat. After the battery cells are neatly arranged in the battery boat, it can be avoided that the battery cells collide with each other due to unevenness when entering and exiting the battery boat, resulting in broken edges.

[0075] Further, if Figure 1 and Figure 3As shown, the shaping module 424 includes a movable plate 4241 and a second drive component 4242. The movable plate 4241 abuts against the cells in the cell boat. The second drive component 4242 is fixedly mounted to the boat support module 3. The movable plate 4241 is connected to the second drive component 4242. When the boat support module 3 is in the positioning position, the second drive component 4242 drives the movable plate 4241 to move along the second horizontal direction Y. Thus, the second drive component 4242, fixedly mounted on the boat support module 3, can precisely control the movement of the movable plate 4241 along the second horizontal direction Y, achieving automated processing, reducing manual operation errors, and ensuring accurate and consistent cell processing. Furthermore, the movable plate 4241 contacts the cells in the cell boat, reducing physical damage to the cells.

[0076] It is understandable that the second driving component 4242 can be a motor, a cylinder or other components that can push the movable plate 4241 to move along the second horizontal direction Y, and this embodiment does not specifically limit this.

[0077] Alternatively, as Figure 1 As shown, the movable plate 4241 includes a first contact member 4241a and a second contact member 4241b. The first contact member 4241a and the second contact member 4241b are arranged in a vertical direction and are used to abut against the battery cells in the battery cell boat. In other words, when the second driving component 4242 drives the movable plate 4241 to push the battery cells, the first contact member 4241a and the second contact member 4241b of the movable plate 4241 abut against the battery cells, pushing the battery cells in the battery cell boat into neat alignment. In this way, the vertical distribution of the first contact members 4241a and the second contact members 4241b ensures contact and uniform support of the battery cells during processing, reduces deformation or damage caused by localized uneven force, and improves the integrity and processing accuracy of the battery cells. Furthermore, the first contact members 4241a and the second contact members 4241b minimize the contact area with the battery cells while ensuring contact, preventing damage to the battery cells caused by uncontrolled movement of the shaping module 424 and impact with the battery cells. Furthermore, by adjusting the relative position of the first contact members 4241a and the second contact members 4241b for battery boats of different specifications, the production requirements of different battery cells can be met.

[0078] In some embodiments, as Figure 1As shown, the boat positioning module 4 also includes a downward positioning assembly 43, which is provided on the boat support module 3. When the boat support module 3 is located at the positioning position, the downward positioning assembly 43 is used to fix the cell boat in a vertical downward direction. In this way, the downward positioning assembly 43, in conjunction with the boat support module 3, fixes the cell boat in the vertical direction, providing a stable support for the cell boat, helping to prevent the cell boat from moving or overturning during processing, thereby enhancing the stability of the entire processing process.

[0079] Furthermore, the downward pressure positioning assembly 43 includes a downward pressure plate 431 and a downward pressure cylinder 432. When the boat support module 3 is in the positioning position, the downward pressure cylinder 432 is positioned vertically downward on the boat support module 3. The downward pressure plate 431 is connected to the downward pressure cylinder 432. The battery boat includes a fifth end face and a sixth end face disposed in a vertically opposed relationship. The downward pressure plate 431 is configured to abut the fifth end face of the battery boat, while the boat support module 3 is configured to abut the sixth end face of the battery boat. In other words, the downward pressure cylinder 432 drives the downward pressure plate 431 vertically downward to position the battery boat placed on the boat support module 3 vertically downward, thereby securing the battery boat. Thus, when the boat support module 3 is in the positioning position, the downward pressure cylinder 432 is positioned vertically downward, enabling precise downward pressure to be applied to the battery boat. This ensures that both the direction and magnitude of the downward pressure are controllable, thereby achieving precise positioning and securing of the battery boat. When the cylinder is operating, the lower pressure plate 431 moves vertically, abutting the fifth end face of the cell boat. Simultaneously, the boat support module 3 abuts the sixth end face of the cell boat, forming a bidirectional support. This not only increases the stability of the cell boat but also prevents it from moving or shaking during processing. Because the cell boat is stably fixed to the positioning station, processing accuracy is greatly improved, reducing processing errors caused by positional deviations.

[0080] In some embodiments, see Figure 5 , Figure 5This is a schematic structural diagram of the passivation contact cell boat fixing device 100 from another perspective disclosed in an embodiment of the present application. The passivation contact cell boat fixing device 100 also includes a rotating shaft 5, which is provided through the boat support module 3 and fixed to the boat support module 3. The rotating shaft 5 is rotatably connected to the base plate 1 so that the boat support module 3 can flip relative to the base plate 1 along the second horizontal direction Y. In other words, the switching of the boat support module 3 between the positioning station and the loading and unloading station relative to the base plate 1 is achieved by the rotating shaft 5. The boat support module 3 flips relative to the base plate 1 along the second horizontal direction Y to switch between the positioning station and the loading and unloading station. In this way, after the cell boat is fixed and the cell boat is processed with the cell, the cell of the cell boat can be taken out and placed in the basket by rotating the rotating shaft. This design does not require extra steps to achieve the switching between the positioning station and the loading and unloading station, making the structure of the device more compact.

[0081] Further, combined with Figure 1 and Figure 5 The base plate 1 is provided with a flip support 6, with a rotating shaft 5 rotatably connected to the flip support 6. The boat support module 3 also includes a support base 33. The rotating shaft 5 passes through the support base 33 and is fixedly connected to the support base 33, so that the support base 33 can flip relative to the base plate 1 along the second horizontal direction Y. Thus, through the design of the flip support 6, when the boat support module 3 flips relative to the base plate 1 along the second horizontal direction Y, the flip support 6 can provide stable support for the flip, preventing large vibrations during the flipping process that could cause the cells in the cell boat to shake and cause impacts that could cause edge breakage and damage to the cells. At the same time, the flip support 6 also provides a certain amount of support for the entire device, making the fixation of the cell boat in the device more stable.

[0082] The second aspect of the present application discloses a transport mechanism, which includes a moving assembly and any of the passivated contact cell boat fixtures described in the aforementioned embodiments. The moving assembly is connected to the bottom plate 1 of the passivated contact cell boat fixture 100, so that the bottom plate 1 can drive the passivated contact cell boat fixture 100 to move within the furnace of the process equipment. The transport mechanism moves the cell boat fixed by the passivated contact cell boat fixture 100 within the furnace of the process equipment to process the cells in the cell boat, thereby preventing the cells from shaking significantly during the movement of the cell boat, avoiding the cell edge breakage caused by the collision between the cell and the cell boat, reducing the defective rate of cell production, and improving the production efficiency of the cell.

[0083] The following briefly describes the operation process of the passivation contact cell boat fixing device 100:

[0084] First, the cell boat loaded with cells is tilted and placed on the boat support module 3 so that the cells in the cell boat are inserted into the auxiliary teeth of the auxiliary tooth support 21. The first driving component 22 drives the auxiliary tooth support 21 to lift up in the vertical direction to fix the cells in the cell boat.

[0085] Next, the first end face of the battery boat along the first horizontal direction X abuts against the first limit plate 411, and the boat-side positioning cylinder 412 moves along the first horizontal direction X to complete the fixation of the battery boat in the first horizontal direction X.

[0086] Furthermore, the positioning cylinder 422 moves along the second horizontal direction Y, contacts the third end surface of the battery boat and pushes the battery boat so that its fourth end surface abuts against the second limiting plate 421, completing the fixation of the battery boat in the second horizontal direction Y;

[0087] Then, the pressing cylinder 432 is actuated to drive the pressing plate 431 to move in the vertical direction and abut against the fifth end face of the battery boat. At this time, the sixth end face of the battery boat abuts against the boat support module 3 to complete the vertical fixation of the battery boat. The shaping module 424 is actuated to push the battery cells in the battery boat so that the battery cells are neatly arranged in the battery boat and the battery cells are processed.

[0088] Finally, after the cells in the cell boat are processed, the boat support module 3 is turned outward 90 degrees along the second horizontal direction Y to deliver the cells in the cell boat into the basket intact.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
