Description

Technical Field

[0001] This invention relates to the field of solar cell technology, and in particular to a graphite boat locking device. Background Technology

[0002] Graphite boats are critical consumables in the production of solar cells. During production, the graphite boats need to be securely fixed to the equipment to ensure the stability of the solar cells during high-temperature processing. However, existing methods of fixing graphite boats typically involve bolts or simple clips, which are prone to loosening under high temperatures. This can lead to displacement of the graphite boat, potentially causing uneven temperature distribution in the solar cells and affecting product quality. Furthermore, manual fixing is not only time-consuming and labor-intensive but also prone to damage due to improper operation. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a graphite boat locking device, which solves the problem that the graphite boat is prone to loosening and displacement under high temperature environment.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a graphite boat locking device, comprising a locking mechanism for fixing a plurality of graphite boat bodies respectively, wherein the plurality of graphite boat bodies are arranged in groups of two, the locking mechanism comprising a boat wing and a U-shaped pressure plate, the boat wing being integrally formed at the end of the graphite boat body, and a limiting slot being provided on the side of each of two adjacent boat wings that are far apart from each other, the upper and lower sides of the U-shaped pressure plate being movably engaged with the two limiting slots respectively, and a locking component for locking the U-shaped pressure plate is also provided on the boat wing.

[0005] As a further optimization of the present invention, the locking assembly includes an inner groove formed in the bottom wall of the limiting slot, a positioning screw hole formed in the inner groove, and limiting holes formed on both the upper and lower sides of the U-shaped pressure plate.

[0006] As a further optimization of the present invention, a positioning screw is provided through the limiting hole, and the positioning screw is threadedly connected to the positioning screw hole.

[0007] As a further optimization of the present invention, threaded holes are provided at the four corners of the graphite boat body, and connecting posts are provided in the four threaded holes on the same horizontal plane.

[0008] As a further optimization of the present invention, the connecting column passes through several threaded holes on the graphite boat body in sequence along the longitudinal direction, and both ends of the connecting column are threaded with nuts.

[0009] As a further optimization solution of the present invention, spacer sleeves threadedly connected to the connecting columns are provided at the four corners between two adjacent graphite boat bodies. The spacer sleeves are fixedly connected to the graphite boat bodies at their bottoms, and the spacer sleeves are used to separate the two graphite boat bodies.

[0010] As a further optimization solution of the present invention, the cross-section of the boat wing is set to a "convex" shape, and the thickness of the boat wing is less than the thickness of the graphite boat body, which is used to reduce the overall weight and ensure the structural strength.

[0011] As a further optimization solution of the present invention, an anti-slip pad is fixedly bonded to the inner surface of the U-shaped pressing plate. The anti-slip pad is made of wear-resistant rubber material and is used to increase the friction between the U-shaped pressing plate and the boat wing.

[0012] By means of the above technical solutions, the present invention provides a graphite boat clamping point device, which has at least the following beneficial effects compared with the prior art: 1. The present invention sets a clamping point mechanism to fix the graphite boat more firmly to ensure its stability during the high-temperature treatment process. The U-shaped pressing plate simultaneously clamps two boat wings distributed up and down, and cooperates with the locking component to further fix the U-shaped pressing plate. Through the threaded connection of the high-precision positioning screw and the positioning screw hole, the stability of the graphite boat body during the high-temperature treatment process is ensured, avoiding product quality problems caused by displacement, reducing manual operation at the same time, reducing labor intensity, and avoiding damage to the graphite boat caused by improper manual operation.

[0013] 2. The present invention synchronously positions several graphite boat bodies by respectively setting threaded holes and connecting columns at the four corners of the graphite boat body, which can not only make the fixation of the graphite boat body more stable, but also help to quickly disassemble and assemble the graphite boat body, greatly shortening the loading and unloading time of the graphite boat and improving the overall production efficiency of the solar cell production line.

[0014] 3. The present invention realizes the rapid fixation and release of the graphite boat body through the integrated molding design of the boat wing and the graphite boat body, the threaded connection of the positioning screw and the positioning screw hole, setting an anti-slip pad in contact with the boat wing on the U-shaped pressing plate, and setting a fixed structure between the connecting column and the spacer sleeve, improving the production efficiency, reducing the operation difficulty, and enhancing the stability and reliability of the device at the same time.

Detailed Implementation

[0017] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] First Embodiment Graphite boats are used in the solar cell production process to support solar cell wafers for high-temperature treatment. However, current methods for fixing graphite boats rely on bolts or clips, which can easily lead to boat displacement, affecting the high-temperature treatment effect of the solar cells and reducing the production quality. To ensure more stable fixing of the graphite boat body 1 and avoid product quality problems caused by displacement, [further details are needed]. Figure 1 - Figure 4 This embodiment provides a graphite boat locking device, which consists of a graphite boat body 1 and a locking mechanism 2. The graphite boat body 1 is arranged in six equally spaced longitudinal directions. The six graphite boat bodies 1 are arranged in three groups of two, and the number of graphite boat bodies 1 is set to an even number.

[0019] In order to improve the stability of the graphite boat body 1 during the high-temperature treatment process, prevent displacement, and ensure the consistency and accuracy of solar cells, a clamping mechanism 2 is used to fix six graphite boat bodies 1 respectively. The clamping mechanism 2 includes boat wings 21 integrally formed at both ends of the graphite boat body 1. The cross-section of the boat wing 21 is set as a "convex" shape. The end with a larger area of the boat wing 21 is fixedly connected to the graphite boat body 1, and the thickness of the boat wing 21 is smaller than that of the graphite boat body 1, which is used to reduce the overall weight and ensure the structural strength. At both ends of each group of graphite boat bodies 1, U-shaped pressing plates 22 are respectively provided. Limiting card slots 23 are opened on the sides of two adjacent boat wings 21 facing away from each other. The upper and lower sides of the U-shaped pressing plate 22 are respectively movably clamped with the two limiting card slots 23. The two U-shaped pressing plates 22 can fix two graphite boat bodies 1 at the same time. During installation, first place the graphite boat body 1 between the two U-shaped pressing plates 22 at the bottom, and then respectively snap the bottoms of the two U-shaped pressing plates 22 into the limiting card slots 23 on the boat wings 21 at both ends of the graphite boat body 1 to preliminarily position the graphite boat body 1.

[0020] In order to achieve fast and simple operation, reduce the time required during the fixation of the graphite boat, and further provide strong fixation, a locking component 24 for clamping the U-shaped pressing plate 22 is also provided on the boat wing 21. The locking component 24 includes an inner groove 241 opened on the inner bottom wall of the limiting card slot 23. A positioning screw hole 242 is opened on the inner groove 241. Limiting holes 243 are opened on both the upper and lower sides of the U-shaped pressing plate 22. A positioning screw 244 is penetrated through the limiting hole 243, and the positioning screw 244 penetrates through the limiting hole 243 and is threadedly connected with the positioning screw hole 242. After the graphite boat body 1 is fixed between the two U-shaped pressing plates 22, rotate the positioning screw 244. The positioning screw 244 penetrates through the limiting hole 243 and is fixed by being threadedly connected with the positioning screw hole 242, so that the boat wing 21 is further fixed on the U-shaped pressing plate 22, thereby making the fixation of the graphite boat body 1 more stable.

[0021] Second Embodiment Refer to Figure 5In this embodiment, to achieve rapid fixing and release of the graphite boat body 1 and reduce the difficulty of disassembly and assembly, the specific implementation method is as follows: threaded holes 12 are respectively provided at the four corners of the graphite boat body 1. Connecting posts 13 are provided in the four threaded holes 12 on the same horizontal plane. The connecting posts 13 pass through the six threaded holes 12 on the graphite boat body 1 in sequence along the longitudinal direction, and the two ends of the connecting posts 13 are threaded with nuts 11. This not only improves the stability of the graphite boat body 1 when it is fixed, but also makes the disassembly and assembly of the graphite boat body 1 more convenient. Spacer sleeves 14 are provided at the four corners between two adjacent graphite boat bodies 1 and are threaded to the connecting posts 13. The spacer sleeves 14 are fixedly connected to the graphite boat body 1 at their bottom. The spacer sleeves 14 are used to separate the two graphite boat bodies 1 and ensure that the separation distance between the two graphite boat bodies 1 is stable and reliable.

[0022] After all the graphite boat bodies 1 are installed, the four connecting posts 13 are rotated and inserted into the four threaded holes 12 on the six graphite boat bodies 1 respectively. At the same time, the connecting posts 13 are also fixed to the spacer sleeves 14 by threaded connection, so that the six graphite boat bodies 1 are fixed.

[0023] Third Embodiment Reference Figure 2 and Figure 4 In this embodiment, to make the graphite boat body 1 more stable, the implementation method is as follows: an anti-slip pad 25 is fixedly bonded to the inner surface of the U-shaped pressure plate 22. The anti-slip pad 25 is made of wear-resistant rubber material and is used to increase the friction between the U-shaped pressure plate 22 and the boat wing 21, to prevent the graphite boat body 1 from shifting during processing, which helps to ensure that the battery cells are heated evenly during the heating process and maintain the production quality of the battery cells.

[0024] This invention uses a locking mechanism 2 to more securely fix the graphite boat, and a U-shaped pressure plate 22 to simultaneously clamp the two vertically distributed boat wings 21. The locking assembly 24 further fixes the U-shaped pressure plate 22. A high-precision positioning screw 244 is threadedly connected to the positioning screw hole 242. At the same time, an anti-slip pad 25 is provided on the U-shaped pressure plate 22 to contact the boat wings 21, and a fixing structure is provided between the connecting column 13 and the spacer sleeve 14 to ensure the stability of the graphite boat body 1 during high-temperature processing and prevent the quality of solar cell production from being affected.

[0025] In the actual installation process, the graphite boat body 1 is first placed between the two bottom U-shaped pressure plates 22. Then, the bottom of the two U-shaped pressure plates 22 is respectively inserted into the limiting grooves 23 on the boat wings 21 at both ends of the graphite boat body 1 to initially position the graphite boat body 1. Then, the positioning screw 244 is rotated. The positioning screw 244 passes through the limiting hole 243 and is fixed to the positioning screw hole 242 by threaded connection, so that the boat wings 21 are further fixed on the U-shaped pressure plates 22. After the six graphite boat bodies 1 are fixed in sequence, the spacer sleeve 14 on the graphite boat body 1 is connected to the threaded hole 12 on the top graphite boat body 1. Then, the four connecting posts 13 are respectively rotated and inserted into the four threaded holes 12 on the six graphite boat bodies 1. At the same time, the connecting posts 13 are also fixed to the spacer sleeve 14 by threaded connection. Then, the two nuts 11 are tightened on both ends of the connecting posts 13 to fix the six graphite boat bodies 1 stably. Then, the high-temperature treatment of the solar panel can be carried out.
