Description

Technical Field

[0001] This application relates to the field of solar cells, and more particularly to an assembly bracket for a graphite boat and a graphite boat installation device. Background Technology

[0002] Solar cells, as key equipment for converting solar energy into electricity, occupy an important position in the renewable energy field. With continuous technological innovation, crystalline silicon solar cells have become the market mainstream due to their high conversion efficiency and high stability. In the solar cell production process, the cell coating process is crucial. Coating forms an anti-reflective film on the cell surface, significantly reducing light reflection and increasing the cell's absorption of light energy, thereby improving the cell's photoelectric conversion efficiency. During coating, the cells must be placed inside a graphite boat and secured by locking points on the boat's blades. The graphite boat, as the carrier of the cells, ensures their stability during the coating process.

[0003] Graphite boats are assembled from individual graphite boat blades. During assembly, workers need to install components such as locking points and ceramic rings onto the graphite boat blades. These components have a significant impact on the performance of the graphite boat and the coating quality of the solar cells. However, during assembly, the device holding the graphite boat blades may wobble. This wobble causes the position of the graphite boat blades to change, making it impossible to accurately install subsequent components into their intended positions. This not only reduces the assembly efficiency of the graphite boat but may also affect its performance in the solar cell coating process due to installation deviations, thus negatively impacting the coating quality of the solar cells.

Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0045] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0046] Solar cells, as key equipment for converting solar energy into electricity, occupy an important position in the renewable energy field. With continuous technological innovation, crystalline silicon solar cells have become the market mainstream due to their high conversion efficiency and high stability. In the solar cell production process, the cell coating process is crucial. Coating forms an anti-reflective film on the cell surface, significantly reducing light reflection and increasing the cell's absorption of light energy, thereby improving the cell's photoelectric conversion efficiency. During coating, the cells must be placed inside a graphite boat and secured by locking points on the boat's blades. The graphite boat, as the carrier of the cells, ensures their stability during the coating process.

[0047] Graphite boats are assembled from individual graphite blades. During assembly, workers need to install components such as locking points, ceramic rings, and ceramic rods onto the graphite blades. These components have a significant impact on the performance of the graphite boat and the coating quality of the solar cells. However, during assembly, the device holding the graphite blades may wobble. This wobble causes the position of the graphite blades to change, preventing subsequent components from being accurately installed in their intended positions. This not only reduces the assembly efficiency of the graphite boat but may also affect its performance in the solar cell coating process due to installation deviations, thus negatively impacting the coating quality of the solar cells.

[0048] If the graphite boat blade shakes and its position shifts when the carding machine is marking the carding point, the carding point may not hit the corresponding mounting hole, but instead hit the graphite boat blade, causing the graphite boat blade to be damaged and unable to be used normally.

[0049] Based on this, this application discloses an assembly bracket for a graphite boat, which can clamp the two sides of the graphite boat leaf eye in the width direction and one or both sides of the graphite boat leaf along its length direction to fix the graphite boat leaf placed on the bearing surface, so that the parts to be installed (clamping points, ceramic rings, etc.) can be installed in the predetermined position.

[0050] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0051] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the assembly bracket 100 for the graphite boat disclosed in an embodiment of this application. Figure 2This is a schematic diagram of the assembly bracket 100 for placing graphite boat blades 5, as disclosed in an embodiment of this application. This application discloses an assembly bracket 100 for assembling multiple graphite boat blades 5 into a graphite boat. The assembly bracket 100 includes a bracket body 1 and multiple clamping components 2. The bracket body 1 has a bearing surface 1a for bearing horizontally placed graphite boat blades 5. The multiple clamping components 2 are disposed on the bracket body 1 and can abut against both sides of the graphite boat blade 5 along its width direction and against one or both sides of the graphite boat blade 5 along its length direction to fix the position of the graphite boat blade 5 on the bearing surface 1a.

[0052] The bearing surface 1a of the support body 1 provides a horizontal placement platform for the graphite boat blade 5, which can ensure that the graphite boat blade 5 remains stable during the assembly process and avoid positional shift or shaking caused by unstable placement, thus providing a basic guarantee for subsequent precise assembly.

[0053] The graphite boat blade 5 is placed horizontally on the bearing surface 1a of the support body 1. After each graphite boat blade 5 is placed, multiple clamping components 2 can clamp the graphite boat blade 5 on both sides along its width and on one or both sides along its length, thereby fixing the graphite boat blade 5 to the bearing surface 1a. The multiple clamping components 2 fix the graphite boat blade 5 from multiple directions, thereby preventing the graphite boat blade 5 from moving in its width and length directions. Through this multi-directional clamping and fixing method, the graphite boat blade 5 can be accurately positioned on the bearing surface 1a, effectively solving the problem of the graphite boat blade 5 changing position due to device shaking during assembly, greatly improving the assembly accuracy of the graphite boat blade 5, thus ensuring that subsequent parts to be installed can be accurately installed in the predetermined position, improving the assembly quality and efficiency of the graphite boat.

[0054] Specifically, the clamping component 2 includes an abutting surface, which abuts against the graphite boat blade 5. This ensures that the position of the graphite boat blade 5 is fixed, and the boat blade is fixed through surface contact, resulting in a better fixing effect. This makes the graphite boat blade 5 subject to uniform force and less likely to be damaged.

[0055] As an optional implementation method, combined with Figures 1 to 3 , Figure 3 This is a schematic diagram of the structure of the clamping assembly 2 disclosed in the embodiments of this application (excluding the reinforcing ribs). The clamping assembly 2 includes a connector 21 and a clamping member 22. The connector 21 is connected to the bracket body 1, and the clamping member 22 is installed on the connector 21. In the clamping direction, the installation position of the clamping member 22 relative to the connector 21 is adjustable so that the clamping member 22 can clamp the graphite boat blade 5. The clamping direction is the direction that is close to or away from the graphite boat blade 5.

[0056] In actual graphite boat assembly, graphite boat blades 5 of different specifications may have different dimensions. Through this position-adjustable design, the clamping assembly 2 can be flexibly adjusted according to the actual width of the graphite boat blade 5 to adapt to the clamping requirements of graphite boat blades 5 of different specifications. This makes the assembly bracket more versatile, applicable to the assembly of various types of graphite boats, without the need to design a specific assembly bracket for each specification of graphite boat, thus reducing production costs.

[0057] During assembly, the adjustable clamping component 22 allows operators to quickly and easily adjust the clamping state according to the actual situation, improving the convenience of assembly operations. Furthermore, when the clamping component 22 wears out or needs replacement, its adjustable position makes the replacement process easier, reducing the difficulty and cost of equipment maintenance.

[0058] In some possible implementations, combined Figures 1 to 3 In terms of adjustment direction, the mounting position of the connector 21 relative to the bracket body 1 is adjustable, and the adjustment direction is parallel to the bearing surface 1a and perpendicular to the clamping direction.

[0059] When different specifications or batches of graphite boat blades 5 need to be assembled, the operator can quickly adjust the connector 21 to the appropriate position without having to disassemble and reassemble the entire clamping assembly 2. This greatly reduces the adjustment time during assembly and improves assembly efficiency. At the same time, for situations where the position of the graphite boat blades 5 may change during assembly, the position of the connector 21 can be adjusted promptly.

[0060] When assembling the graphite boat blade 5, not only can the clamping member 22 be adjusted in the clamping direction to accommodate different sizes and positions of the graphite boat blade 5, but the connecting member 21 can also be fine-tuned in another dimension. When there is a certain deviation in the placement of the graphite boat blade 5 on the bearing surface 1a, or when it is necessary to accurately calibrate the relative positions between multiple graphite boat blades 5, this can be achieved by moving the connecting member 21 along the adjustment direction. This multi-dimensional precise adjustment capability can better ensure the positional accuracy of the graphite boat blade 5 on the bearing surface 1a, thereby improving the overall assembly quality of the graphite boat.

[0061] In some alternative implementations, combined with Figure 3 The clamping assembly 2 also includes a first fixing member 23, a first mounting hole 21a for the connecting member 21, and a guide hole 22a for the clamping member 22. The first fixing member 23 is detachably connected between the mounting hole and the guide hole 22a. The guide hole 22a extends along the clamping direction so that the clamping member 22 can be adjusted in position along the clamping direction.

[0062] The guide hole 22a provides a clear guide for adjusting the position of the clamping member 22 along the clamping direction. The operator can precisely adjust the position of the clamping member 22 under the guidance of the guide hole 22a by disassembling and reinstalling the first fixing member 23, so as to meet the clamping requirements of graphite boat blades 5 of different widths.

[0063] When you want to adjust the position of the clamping assembly 2 along the clamping direction, remove the first fixing member 23, adjust the position of the clamping member 22 relative to the connector 21 along the direction of the guide hole 22a, and then insert the first fixing member 23 between the first mounting hole 21a and the guide hole 22a. This precise adjustment method ensures effective clamping of the graphite boat blade 5 and avoids damage to the graphite boat blade 5 or insecure fixation due to improper clamping force.

[0064] Optionally, the clamping assembly 2 further includes a second fixing member. The bracket body 1 is provided with a guide groove 1b, and the connector 21 is provided with a second mounting hole 21b. The second fixing member is connected between the guide groove 1b and the second mounting hole 21b. The guide groove 1b extends along the adjustment direction so that the connector 21 can be adjusted in the adjustment direction.

[0065] The guide groove 1b provides guidance for position adjustment along the adjustment direction. A second fixing member connects the guide groove 1b of the support body 1 to the second mounting hole 21b of the connector 21, thereby adjusting the position of the connector 21 relative to the support body 1 in the adjustment direction. When adjusting the position of the clamping assembly 2 along the adjustment direction, the second fixing member is removed, the position of the connector 21 relative to the support body 1 is adjusted along the direction of the guide groove 1b, and then the second fixing member is inserted between the second mounting hole 21b and the guide groove 1b. This structure allows the connector 21 to move smoothly along the guide groove 1b, thus flexibly adjusting its position in the adjustment direction. When dealing with graphite boat blades 5 of different specifications or positional deviations during assembly, the connector 21 can be easily fine-tuned, improving assembly accuracy and flexibility.

[0066] Optionally, the first fixing member 23 and the second fixing member are screws. The first mounting hole 21a and the second mounting hole 21b are provided with threads. The fixing member is tightened by thread engagement with the mounting hole. The head of the nut abuts against the clamping member 22, thereby realizing the connection between the connecting member 21 and the clamping member 22.

[0067] Optionally, combined Figure 3 and Figure 4 , Figure 4This is another structural schematic diagram (including reinforcing ribs) of the clamping assembly 2 disclosed in the embodiments of this application. The connector 21 includes a guide plate 211, a first connecting plate 212 and a first reinforcing rib 213. The guide plate 211 is connected to the bracket body 1. In the adjustment direction, the installation position of the guide plate 211 relative to the bracket body 1 is adjustable. The first connecting plate 212 is connected to the guide plate 211 and the first connecting plate 211 has an angle. The first reinforcing rib 213 is connected between the guide plate 211 and the first connecting plate 212.

[0068] The guide plate 211 provides a stable guide for the position adjustment of the connector 21. This allows the guide plate 211 to move precisely along the guide groove 1b during the adjustment process of the connector 21, which is parallel to the bearing surface 1a and perpendicular to the clamping direction. This ensures the accuracy and stability of the adjustment and helps to improve the positioning accuracy of the graphite boat blade 5 during the assembly process.

[0069] The first reinforcing rib 213 effectively enhances the structural strength and stability of the connector 21, enabling it to withstand greater forces without deformation when clamping the graphite boat blade 5. This reduces positional deviations of the graphite boat blade 5 caused by structural deformation, improving assembly accuracy and reliability. Furthermore, the presence of the reinforcing rib can disperse stress, reducing the risk of fatigue damage to the connector 21 during long-term use and extending its service life.

[0070] In some embodiments, the clamping member 22 includes a second connecting plate 221, a clamping plate 222, and a second reinforcing rib 223. The second connecting plate 221 is connected to the first connecting plate 212, and the mounting position of the second connecting plate 221 relative to the first connecting plate 212 is adjustable in the clamping direction. The clamping plate 222 is connected to the second connecting plate 221, and the clamping plate 222 and the second connecting plate 221 have an angle. The clamping plate 222 is used to clamp the graphite boat blade 5. The second reinforcing rib 223 is connected between the second connecting plate 221 and the clamping plate 222.

[0071] The second connecting plate 221 allows for precise positional adjustment of the clamping plate 222 in the direction of approaching or moving away from the graphite boat blade 5. The position of the clamping plate 222 can be precisely adjusted according to the specific size and shape of the graphite boat blade 5, ensuring uniform and moderate clamping force and guaranteeing the stability of the graphite boat blade 5 during assembly. The clamping plate 222 can better conform to the surface of the graphite boat blade 5, increasing the contact area with the graphite boat blade 5, thereby more effectively clamping the graphite boat blade 5.

[0072] The second reinforcing rib 223 enhances the overall structural strength and rigidity of the clamping component 22. When clamping and fixing the graphite boat blade 5, it can withstand greater external forces, reducing the possibility of positional displacement of the graphite boat blade 5 due to deformation of the clamping component 22, and improving assembly accuracy and consistency. Furthermore, the second reinforcing rib 223 also helps to disperse clamping forces, making the entire clamping component 22 structure more stable and improving its reliability and durability during long-term use.

[0073] In some embodiments, combined with Figure 1 and Figure 4 The clamping member 22 is provided with a buffer member 224, and the clamping member 22 abuts against the graphite boat blade 5 through the buffer member 224.

[0074] The graphite boat blade 5 is typically a relatively fragile component. If it comes into direct, rigid contact with the clamping component 22 during assembly, it is prone to scratches, cracks, or even damage due to excessive clamping force or uneven contact. The presence of the buffer component 224 provides a buffering effect between the clamping component 22 and the graphite boat blade 5, avoiding direct rigid contact between the two. This effectively protects the surface integrity and structural performance of the graphite boat blade 5, and improves the yield rate of the graphite boat blade 5.

[0075] Because the buffer 224 is deformable, it can accommodate minor differences in size and shape of the graphite boat blade 5 to a certain extent. Even if the graphite boat blade 5 has some tolerances or irregularities, the buffer 224 can achieve good fit and clamping through its own deformation, improving the adaptability and versatility of the assembly bracket for graphite boat blades 5 of different specifications.

[0076] Optionally, the buffer 224 has a plate-like structure, and the buffer 224 makes surface contact with the graphite boat blade 5, which makes it less likely to damage the graphite boat blade 5.

[0077] Secondly, combining Figure 5 , Figure 5 This is a schematic diagram of the structure of the graphite boat installation device 200 disclosed in the embodiments of this application. The graphite boat installation device 200 includes an assembly bracket 100 for a graphite boat as described in any of the first aspects and an assembly module 4. The assembly module 4 is configured to assemble the component to be installed onto the graphite boat blade 5 to assemble it into a graphite boat.

[0078] The components to be installed include clamping points, ceramic rings, and ceramic rods. Taking clamping points as an example, the graphite boat blade 5 has mounting holes, and the clamping points need to be installed into these holes. The graphite boat blade 5 is then fixed to the bearing surface 1a by the clamping assembly 2. Multiple clamping assemblies 2 fix the graphite boat blade 5 from multiple directions, thereby preventing the graphite boat blade 5 from moving in its width and length directions. This multi-directional clamping and fixing method can accurately position the graphite boat blade 5 on the bearing surface 1a, effectively solving the problem of the graphite boat blade 5 changing position due to device shaking during assembly. This greatly improves the assembly accuracy of the graphite boat blade 5, ensuring that the clamping points can be accurately installed into the corresponding mounting holes without breaking the graphite boat blade 5, thus improving the assembly quality and efficiency of the graphite boat.

[0079] Optionally, combined Figures 5 to 7 , Figure 6 This is a schematic diagram of the structure of the inner boat blade 51 disclosed in the embodiments of this application. Figure 7 This is a schematic diagram of the structure of the outer boat blade 52 disclosed in the embodiments of this application. The assembly module 4 includes a sensor 41, and the graphite boat blade 5 includes a battery cell placement position 5a for placing battery cells. The multiple graphite boat blades 5 include multiple inner boat blades 51 and two outer boat blades 52. In the vertical direction, the multiple inner boat blades 51 are located between the two outer boat blades 52. The battery cell placement position 5a of the inner boat blade 51 is a hollow structure, and the battery cell placement position 5a of the outer boat blade 52 is a solid structure. The solid structure and the hollow structure are correspondingly arranged in the vertical direction. The sensor 41 is located above the battery cell placement position 5a to detect the distance between the sensor 41 and the lowermost outer boat blade 52 in the vertical direction.

[0080] The thickness of the inner boat blade 51 of the graphite boat is usually less than that of the outer boat blade 52. Therefore, the thickness of the locking point on the inner boat blade 51 is also less than that on the outer boat blade 52. If the outer boat blade 52 is placed in the middle of the graphite boat along its own thickness direction, when the module 4 is assembling the locking point, the thinner locking point will be mistakenly assembled onto the outer boat blade 52. Alternatively, if the inner boat blade 51 is placed on the outermost side of the graphite boat along its own thickness direction, the thicker locking point will be mistakenly assembled onto the inner boat blade 51, causing the locking point to protrude. Consequently, when the solar cells inside the graphite boat are coated, the solar cells will shake inside the graphite boat, causing the insulating layer (such as the back passivation film) at the edge of the solar cells to be damaged, resulting in PN junction isolation failure, increasing the risk of leakage, affecting the performance of the solar cells, and causing frequent cell picking when the optical inspection equipment detects defects on the surface of the solar cells, affecting production and the risk of customer complaints.

[0081] Taking the sensor 41 as an example of a photoelectric sensor, when the inner boat leaf 51 is correctly placed, the sensor 41 can emit light that passes through the hollow structure of the inner boat leaf 51 and hits the bottom outer boat leaf 52. The distance sensed by the sensor 41 is the distance between the sensor 41 and the bottom outer boat leaf 52. When the outer boat leaf 52 is mistakenly placed in the position of the inner boat leaf 51, the light hits the outer boat leaf 52 directly, and the distance sensed by the sensor 41 is the distance between the sensor 41 and the mistakenly placed outer boat leaf 52. Therefore, before placing the second outer boat leaf 52, the distance sensed by the sensor 41 should always be the distance between the sensor 41 and the bottom outer boat leaf 52. However, when the outer boat leaf 52 is mistakenly placed in the position of the inner boat leaf 51, the distance sensed by the sensor 41 will suddenly decrease. The sensor 41 is electrically connected to the checkpoint machine, and at this time, the sensor 41 will send an NG signal to the checkpoint machine. The checkpoint machine stops placing the checkpoint, thus reminding the operator to replace the boat leaf in time.

[0082] In some possible implementations, combined Figure 5 The assembly module 4 includes a transmitter 42, and the assembly bracket 100 of the graphite boat also includes a reflector 3. The reflector 3 is disposed on the bearing surface 1a, and the transmitter 42 is located above the reflector 3. The transmitter 42 can emit laser. When the transmitter 42 receives the laser reflected by the reflector 3, the bracket body 1 is in the assembly position. The assembly position is configured for the assembly module 4 to assemble the part to be installed onto the graphite boat blade 5.

[0083] The transmitter 42 emits a laser. When the transmitter 42 receives the laser reflected by the reflector 3, it indicates that the bracket body 1 is in the assembly position. This method utilizes the linear propagation and reflection characteristics of laser to accurately determine whether the bracket body 1 is in the correct assembly position. It provides a clear positional reference for the assembly module 4 to accurately assemble the parts to be installed onto the graphite boat blade 5, avoiding assembly deviations caused by inaccurate positioning and helping to improve assembly accuracy and product quality.

[0084] The arrangement of the transmitter 42 and reflector 3 facilitates integration with automated assembly systems.
