Description

Technical Field

[0001] This utility model relates to the field of passivation coating equipment, and further to a wafer cassette and passivation coating equipment. Background Technology

[0002] In photovoltaic (PV) processes, solar cells need to be strung together after slicing. Research shows that adding a sidewall passivation process after slicing can improve power generation efficiency, and the cell cassette is the core carrier that carries the solar cells into the coating equipment.

[0003] Taking CN220382062U as an example, existing cell boxes use an automatic snap-fit ​​structure to lock the cover and press the cells together with clamping components. However, this automatic snap-fit ​​structure requires a large clearance between the snap-fit ​​components and the cover, resulting in a reduced capacity for a cell box of the same size, thus decreasing the effective capacity of the cell box. The coating environment easily causes aluminum oxide buildup on the snap-fit's moving parts, leading to jamming or failure. Furthermore, this automatic snap-fit ​​structure relies on manual operation, resulting in low automation and limited efficiency.

[0004] In the clamping component, the clamping plate is rigidly connected to the cover plate through the guide post, and the spring provides downward pressure. Ideally, it should first contact the battery cell to buffer the pressure, but the rigid constraint of the guide post amplifies the guide gap, which can cause jamming. Moreover, the surface flatness deviation after the battery cells are stacked causes the clamping plate to fail to fit adaptively, resulting in battery cell shaking and potential breakage. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to provide a film cassette and passivation coating equipment. By using a push rod to move the movable plate and cause the pin to disengage from the ear plate, the cover plate can be quickly disassembled, significantly reducing the complexity of the opening operation and the cost of the equipment. The required clearance between the pin and the ear plate is small, resulting in a larger capacity for the same size film cassette, which can improve efficiency. The pin and push rod are located inside the cover plate and ear plate, avoiding jamming caused by the accumulation of aluminum oxide during the coating process.

[0006] To achieve the above objectives, this utility model provides a film box, including a base plate, several side plates and a cover plate;

After the pin penetrates the cover plate, it is inserted into the ear plate to lock the cover plate. The other side of the movable plate is elastically connected to the cover plate through a first elastic element.

[0009] During disassembly, the push rod pushes the movable plate to slide and compress the first elastic element, causing the pin to disengage from the ear plate.

The floating pressure plate is supported at the bottom of the cover plate by a plurality of second elastic members. The second elastic members are disposed at the four corners of the bottom of the cover plate. The floating pressure plate is adapted to press the battery cells under the action of the second elastic members.

[0016] In some embodiments, the second elastic element is a V-shaped spring sheet, with its two ends connected to the bottom of the cover plate and the top of the floating pressure plate, respectively.

[0017] In some embodiments, a pair of side plates are disposed on both sides of the base plate in the length direction, such that both sides of the base plate in the width direction form a coated surface;

[0018] Alternatively, a pair of the side plates are disposed on both sides of the base plate in the length direction, and another side plate is disposed on one side of the base plate in the width direction, so that the other side of the base plate in the width direction forms a coated surface.

[0019] According to another aspect of this application, a passivation coating apparatus is further provided, including any one of the preferred embodiments described above, a wafer cassette and a coating cavity, wherein the wafer cassette is disposed inside the coating cavity.

[0020] Compared with the prior art, the wafer cassette and passivation coating equipment provided by this utility model have at least one of the following beneficial effects:

[0023] 3. The fork can easily move the two movable plates toward each other, thereby disengaging the pins from the ear plates and unlocking the cover.

[0024] 4. When installing the cover plate, the positioning pin can be accurately inserted into the positioning hole, thereby realizing the pre-positioning function of the cover plate and ensuring the stability of the cover plate in the initial stage of installation.

It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.

[0037] refer to Figures 1 to 3This utility model provides a cartridge, including a base plate 1, several side plates 2, and a cover plate 3; the side plates 2 are disposed at the side ends of the base plate 1, and the cover plate 3 is detachably disposed at the top of the side plates 2; wherein, the top of the side plates 2 is provided with several ear plates 21, and the upper surface end of the cover plate 3 is provided with a movable groove 31, in which a movable plate 32 is slidably disposed; one side of the movable plate 32 is provided with a pin 33 and a push rod 35 that penetrate the cover plate 3 along the length direction of the cover plate 3; the pin 33 penetrates the cover plate 3 and inserts into the ear plate 21 to lock the cover plate 3; the other side of the movable plate 32 is elastically connected to the cover plate 3 through a first elastic member 34; when disassembling, the push rod 35 pushes and moves the movable plate 32 to slide and compress the first elastic member 34, causing the pin 33 to disengage from the ear plate 21.

[0038] In this embodiment, the push rod 35 pushes the movable plate 32 to move and causes the pin 33 to disengage from the ear plate 21, thereby achieving quick disassembly of the cover plate 3, which greatly reduces the complexity of the opening operation and the equipment cost; the required fitting gap between the pin 33 and the ear plate 21 is small, and the capacity of the same size film box is larger, which can improve efficiency; the pin 33 and the push rod 35 are located inside the cover plate 3 and the ear plate 21, avoiding the jamming phenomenon caused by the accumulation of aluminum oxide during the coating process.

[0039] Specifically, the side plate 2 is located at the end of the side of the base plate 1, forming a relatively stable frame structure for the entire tablet cassette. The cover plate 3 is detachably installed on top of the side plate 2, greatly facilitating the use and maintenance of the tablet cassette. The detachable structure of the cover plate 3 includes an ear plate 21, a movable plate 32, and a pin 33. The ear plate 21 is located on top of the side plate 2 and has a fixing hole suitable for inserting the pin 33. The end of the upper surface of the cover plate 3 has a movable groove 31, in which the movable plate 32 is slidably arranged. One side of the movable plate 32 is fixedly connected to the pin 33, which is adapted to pass through the cover plate 3 along its length and connect to the ear plate 21. When it is necessary to lock the cover plate 3, the pin 33 can pass through the cover plate 3 and insert into the ear plate 21, thereby achieving a tight fixation between the cover plate 3 and the side plate 2, ensuring the sealing and stability of the tablet cassette during use. The other side of the movable plate 32 is elastically connected to the cover plate 3 through a first elastic element 34. When disassembling the cover plate 3, the operator or automated equipment only needs to move the movable plate 32 to compress the first elastic element 34 and cause it to slide, thereby driving the pin 33 to smoothly disengage from the ear plate 21, thus easily unlocking and disassembling the cover plate 3. When installing the cover plate 3, simply place the cover plate 3 at the designated position on the top of the side plate 2 and release the movable plate 32 to allow the first elastic element 34 to release its elasticity and push the pin 33 into the ear plate 21. The movable groove 31 has a first sidewall and a second sidewall on both sides along the length of the cover plate 3. The first sidewall has a first channel 311, and the first elastic element 34 is elastically connected to the first channel 311, providing stable elastic support for the movable plate 32 and ensuring that the first elastic element 34 maintains good reset performance and operational sensitivity during sliding. A second channel 312 is provided on the second side wall, and the pin 33 is adapted to pass through the second channel 312 to ensure that the pin 33 is subjected to uniform force and moves smoothly during sliding, thereby achieving precise and reliable docking or disengagement with the ear plate 21, further enhancing the stability and reliability of the locking and unlocking operation of the cover plate 3. The first channel 311 and the second channel 312 are both arranged along the length direction of the cover plate 3.

[0040] More specifically, this application uses a push rod 35 to move the movable plate 32. The push rod 35 is fixed to one side of the movable plate 32 and along the length of the cover plate 3. A third channel 313 is provided on the second side wall of the movable groove 31. The push rod 35 is adapted to pass through the third channel 313. The pneumatic fingers of the automatic equipment can push the push rod 35 inward and move the movable plate 32, while fixing the automatic equipment and the cover plate 3 together, so as to realize the efficient unlocking and quick disassembly of the cover plate 3, which greatly reduces the complexity of the opening operation and the equipment cost.

[0041] In detail, the push rod 35 is fixed to one side of the movable plate 32. At this time, the push rod 35 and the pin 33 are located on the same side of the movable plate 32. A third channel 313 is correspondingly provided on the second side wall of the movable groove 31, through which the push rod 35 can pass. During disassembly, the pneumatic fingers of the automated equipment can insert into the outer end of the third channel 313 and push the push rod 35 inward, thereby pushing the movable plate 32 and the pin 33 to move, achieving efficient unlocking. During installation, the automated equipment inserts the pneumatic fingers from both sides into the third channel 313 of the cover plate 3, pushes the push rod 35 inward, and simultaneously grasps and lifts the cover plate 3. The positioning pin 36 positions the cover plate 2 at the designated position on top. After placement, the automated equipment releases the pneumatic fingers, which withdraw from the third channel 313 of the cover plate 3. At the same time, the pin 33 extends out and inserts into the ear plate 21 under the recoil action of the first elastic element 34. At this time, the unlocking and lifting actions of the cover plate 3 are integrated into one, which can be completed by a single automated device. On highly automated production lines, the integration of equipment and operational efficiency are effectively improved.

[0042] This application utilizes a push rod 35 to enable the flexible movement of the movable plate 32, which in turn disengages the pin 33 from the ear plate 21. This allows automated equipment to directly and effortlessly unlock the cover plate 32, significantly simplifying the disassembly process. The design is simple, easy to assemble, and cost-effective. Compared to traditional opening methods, this reduces the complexity of the opening operation and effectively lowers the cost of automated equipment, resulting in economic benefits. Secondly, the small clearance between the pin 33 and the ear plate 21 allows for a larger storage capacity for the same size film cassette without altering its overall dimensions. This improves efficiency and space utilization, enhancing the film cassette's performance. Finally, the pin 33, under normal conditions, is located inside the cover plate 3 and ear plate 21, effectively preventing alumina buildup during the coating process. This prevents jamming caused by alumina accumulation, improving the reliability and durability of the film cassette and ensuring its stability and efficiency during long-term use.

[0043] Preferably, a pair of ear plates 21 are spaced apart along the width direction of the cover plate 3, a pair of push rods 35 are spaced apart along the width direction of the cover plate 3 and located between the ear plates 21, and a pair of pins 33 are located outside the push rods 35 and correspond to the ear plates 21.

[0044] It is worth noting that automated equipment is not within the scope of protection of this application, therefore, this application will not elaborate further on automated equipment. In this embodiment, the automated equipment can either directly push the movable plate 32 or clamp the movable plate 32 to push the movable plate 32 to move.

[0045] Furthermore, each of the upper surfaces at both ends of the cover plate 3 along its length is provided with a movable groove 31, and a fork 321 is fixedly connected to the top of the movable plate 32. The top of the fork 321 protrudes from the upper surface of the cover plate 3, and the two movable plates 32 move toward each other through the fork 321 so that the pins 33 disengage from the ear plates 21 respectively.

[0046] In this embodiment, the fork 321 can easily drive the two movable plates 32 to move towards each other, thereby causing the pins 33 to disengage from the ear plates 21 and unlocking the cover plate 3.

[0047] Specifically, a fork 321 is fixed to the top of the movable plate 32. The top of the fork 321 protrudes from the upper surface of the cover plate 3, forming an external structure that facilitates operation. When it is necessary to unlock the cover plate 3, the operator or automated equipment only needs to push the fork 321 to move the two movable plates 32 toward each other. As the movable plates 32 move, the pins 33 connected to their sides slide synchronously and disengage from the ear plates 21, ultimately achieving the disassembly of the cover plate 3. This process is not only simple to operate, but the fork 321 protruding from the upper surface of the cover plate 3 makes applying force to the fork 321 more direct and efficient, greatly improving the convenience and reliability of unlocking the cover plate 3. At the same time, compared with the traditional cover opening method, this unlocking method reduces the complexity of operation, reduces manual intervention, improves production efficiency, and provides strong support for the integration of automated production lines.

[0048] It is worth noting that the key point of the previous embodiment is the use of push rod 35 and third channel 313. The automated equipment is inserted into the third channel 313 to realize the movement of movable plate 32 and the fixed connection between cover plate 3 and automated equipment. Unlocking and clamping of cover plate 3 are completed by the same automated equipment, effectively improving equipment integration and operational efficiency. The difference between the previous embodiment and this embodiment lies in how to automatically push movable plate 32. In this embodiment, the fork 321 can be manually or automatically moved to drive the two movable plates 32 to slide towards each other, so that the pin 33 disengages from ear plate 21. Of course, this embodiment can also achieve the effect of the previous embodiment by providing a channel on the fork 321, that is, inserting the pneumatic finger of the automated equipment into the channel of the fork 321, and then pushing the fork 321 and lifting cover plate 3. These two embodiments are not mutually exclusive, but complementary. In practical applications, the appropriate type of film cassette can be flexibly selected based on specific working conditions and equipment conditions, or the two can be combined to make the film cassette both suitable for the convenience of manual operation and meet the high efficiency of automated production, thus greatly expanding the scope of application of the film cassette and enhancing its versatility and practicality in different environments.

[0049] Furthermore, the bottom of the cover plate 3 is provided with a positioning pin 36, and the top of the side plate 2 is provided with a corresponding positioning hole 22. The positioning pin 36 is suitable for insertion into the positioning hole 22 to pre-position the cover plate 3.

[0050] In this embodiment, when the cover plate 3 is installed, the positioning pin 36 can be accurately inserted into the positioning hole 22, thereby realizing the pre-positioning function of the cover plate 3, ensuring the stability of the cover plate 3 in the initial stage of installation, so that the subsequent pin 33 and the second channel 312 can be quickly and accurately aligned, greatly simplifying the installation process and improving the operating efficiency; at the same time, it can also effectively reduce installation errors caused by position deviation, reduce the defect rate in the production process, and improve the overall production efficiency.

[0051] Furthermore, a floating pressure plate 4 is provided at the bottom of the cover plate 3. The floating pressure plate 4 is supported at the bottom of the cover plate 3 by a number of second elastic members 41. The second elastic members 41 are located at the four corners of the bottom of the cover plate 3. The floating pressure plate 4 is adapted to press the battery cells under the action of the second elastic members 41.

[0052] In this embodiment, the floating pressure plate 4 has uniform contact force with the battery cell and better fit, which avoids the risk of fragmentation caused by uneven force on the battery cell due to the pressure plate, and also avoids plating around due to better fit with the battery cell.

[0053] Specifically, the second elastic element 41 is installed at the four corners of the bottom of the cover plate 3, forming a stable support structure. This ensures that the floating pressure plate 4 experiences uniform force and excellent fit when pressing the battery cells, further improving the fixing effect and processing accuracy of the battery cells. It effectively avoids the risk of fragmentation caused by uneven local force on the battery cells due to the pressure plate, reduces processing errors and quality problems caused by battery cell displacement or loosening, and greatly improves product integrity and pass rate. The floating pressure plate 4 can automatically adjust its tilt according to the flatness of the battery cells, allowing it to adapt flexibly to battery cells with different flatness levels, ensuring a tight fit. When there are slight unevennesses on the surface of the battery cells, the floating pressure plate 4 can compensate for these unevennesses through its tilt adjustment, thus ensuring consistent pressing effect. This not only enhances the equipment's compatibility with different types and specifications of battery cells but also further reduces processing defects caused by uneven battery cell surfaces, improving overall production efficiency and product quality. Meanwhile, because the floating pressure plate 4 can fit tightly and evenly against the surface of the battery cell, it effectively reduces the gap between the edge of the battery cell and the pressure plate, thereby significantly reducing the probability of plating around the cell and improving the quality and aesthetics of the product.

[0054] Preferably, the second elastic element 41 is a V-shaped spring sheet, with its two ends connected to the bottom of the cover plate 3 and the top of the floating pressure plate 4, respectively. This provides sufficient pressure to ensure the floating pressure plate 4 tightly adheres to the battery cell without damaging it due to excessive pressure. The second elastic element 41 can also be a spring sheet of other shapes; this application does not further limit its application, and these are all simple variations of this application.

[0055] It is worth noting that the film cassette of this application can be coated either simply or on both sides, adapting to different coating requirements. For simple coating, only one pair of side plates 2 need to be positioned on both sides of the base plate 1 along its length, so that both sides of the base plate 1 form coating surfaces along its width. For double-sided coating, only one pair of side plates 2 need to be positioned on both sides of the base plate 1 along its length, and another side plate 2 needs to be positioned on one side of the base plate 1 along its width, so that the other side of the base plate 1 along its width forms a coating surface.

[0056] Furthermore, this application provides a passivation coating apparatus, including a wafer cassette and a coating cavity as described in any of the above embodiments, wherein the wafer cassette is disposed inside the coating cavity.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
