Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a calibration device. Background Technology

[0002] With the advancement of the dual-carbon strategy and the technological upgrading of the photovoltaic industry, passivated contact solar cells have become the mainstream technology route in the industry due to their high conversion efficiency. In the silicon wafer production process, the graphite boat, as the core tooling for carrying out key processes such as chemical vapor deposition and front and back surface coating of silicon wafers, directly determines the quality of the production process due to the structural precision of the graphite boat.

[0003] The snap-fit ​​components on the graphite boat are used to support the silicon wafer, ensuring it adheres tightly to the boat blades. However, during production, these snap-fit ​​components are often misaligned relative to the boat blades, resulting in gaps between the silicon wafer and the boat blades. This leads to unsightly dot marks formed during silicon nitride deposition. Current technology involves emptying the silicon wafer, moving the graphite boat to a cleaning room, disassembling and correcting the faulty snap-fit ​​components, and then reassembling and transporting them back to the workshop to correct their position. This entire correction process is time-consuming, and there is a risk of the graphite boat blades breaking during disassembly and reassembly. Utility Model Content

[0004] This application discloses a correction device that can correct the relative position of the snap-fit ​​component with respect to the thickness direction of the graphite boat blade, preventing gaps between the silicon wafer and the boat blade caused by snap-fit ​​component misalignment, thereby preventing defects such as the formation of dot marks due to silicon nitride deposition during silicon wafer processing.

[0005] To achieve the above objectives, this application discloses a correction device for correcting a snap-fit ​​member on the blade of a graphite boat to a centered position. The snap-fit ​​member includes a first surface and a second surface that are opposite to each other along a first direction. The blade includes a third surface and a fourth surface that are opposite to each other along the first direction. The first surface and the third surface have the same orientation. The first direction is the thickness direction of the blade. The centered position is the position of the snap-fit ​​member when the distance from the first surface to the third surface is equal to the distance from the second surface to the fourth surface. The correction device includes:

[0006] The first and second clamping rods are rotatably connected.

[0007] A first alignment member is disposed on the first clamping rod. The first alignment member includes a first abutting surface for abutting against the third surface of the boat blade. The first abutting surface is provided with a first groove for accommodating the snap-fit ​​member. The bottom wall of the first groove abuts against the first surface of the snap-fit ​​member. There is a first preset distance between the bottom wall of the first groove and the first abutting surface. The first preset distance is the distance from the first surface to the third surface when the snap-fit ​​member is in the central position.

[0008] The second correction element is disposed on the second clamping rod and corresponds to the position of the first correction element. The second correction element is used to abut against the second surface of the snap-fit ​​element.

[0009] As an optional implementation, the first end of the first clamping rod is rotatably connected to the first end of the second clamping rod. The correction device further includes a first grip and a second grip. The first end of the first grip is connected to the first end of the first clamping rod, and the first end of the second grip is connected to the first end of the second clamping rod. The first correction element is disposed at the end of the first clamping rod away from the first grip, and the second correction element is disposed at the end of the second clamping rod away from the second grip. When the first grip and the second grip approach each other, the first clamping rod and the second clamping rod approach each other.

[0010] As an optional implementation, the second correction member has a second groove on the side facing the first clamping rod. The second groove is used to accommodate the snap-fit ​​member, and the bottom wall of the second groove is used to abut against the second surface of the snap-fit ​​member.

[0011] As an optional implementation, the depth of the second groove along the first direction is less than the distance from the second surface to the fourth surface when the snap-fit ​​is in the centered position.

[0012] As an optional implementation, the cross-sectional area of ​​the first groove perpendicular to the first direction is greater than the maximum cross-sectional area of ​​the snap-fit ​​member perpendicular to the first direction; the cross-sectional area of ​​the second groove perpendicular to the first direction is greater than the maximum cross-sectional area of ​​the snap-fit ​​member perpendicular to the first direction.

[0013] As an optional implementation, the first clamping rod is provided with a first limiting part, and the second clamping rod is provided with a second limiting part. When the first clamping rod and the second clamping rod approach each other, the first limiting part and the second limiting part abut against each other before the first correction member and the second correction member. When the first limiting part and the second limiting part abut against each other, the distance between the first correction member and the second correction member is greater than the thickness of the boat blade.

[0014] As an optional implementation, the first limiting part is a limiting protrusion, the first limiting part is disposed on the side of the first clamping rod facing the second clamping rod, and the first limiting part is disposed at the end of the first clamping rod near the first grip handle.

[0015] As an optional implementation, the second limiting part is a limiting protrusion, the second limiting part is disposed on the side of the second clamping rod facing the first clamping rod, and the second limiting part is disposed at the end of the second clamping rod near the second grip handle.

[0016] As an optional implementation, the first corrector is circular, and the diameter of the first corrector is greater than the width of the first clamping rod.

[0017] As an optional implementation, along the first direction, the projected area of ​​the first corrector is larger than the projected area of ​​the second corrector.

[0018] As an optional implementation, the first correction member further includes a connecting part and an abutting part that are connected to each other. One end of the connecting part is connected to the first clamping rod, and the other end of the connecting part is connected to the abutting part. Along the first direction, the projected area of ​​the connecting part is smaller than the projected area of ​​the abutting part.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] The calibration device provided in this application embodiment can maintain the balance of the snap-fit ​​component in the first direction and fix it in a central position on the boat blade through the contact relationships between the first contact surface and the third surface, the first groove and the first surface, and the second calibration component and the second surface. This allows for adjustment of the snap-fit ​​component's position without disassembling the boat blade, ensuring the relative position between the silicon wafer and the boat blade, preventing gaps between the silicon wafer and the boat blade, which could lead to poor appearance due to silicon nitride deposition and dot marks. This saves time on disassembling and installing the graphite boat, ensuring production and maintenance efficiency. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] In this application, the terms "upper," "lower," "top," "bottom," "inner," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0034] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. 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.

[0035] Furthermore, the terms "set up," "equipped with," and "connected" 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.

[0036] 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.

[0037] Against the backdrop of the vigorous advancement of the global dual-carbon strategy and the continuous upgrading of photovoltaic industry technology, passivated contact cells, with their significant advantage of high conversion efficiency, have become the mainstream technology in the photovoltaic industry. This development trend has placed more stringent requirements on related production processes and equipment to ensure that product quality and production efficiency can meet market demands.

[0038] In the critical stages of silicon wafer production, the graphite boat plays a vital role. As a core tooling fixture for carrying silicon wafers through key processes such as chemical vapor deposition and front and back surface coating, the structural precision of the graphite boat directly determines the quality of the production process. Specifically, the clamping components on the graphite boat are used to support the silicon wafer, ensuring that the wafer can be tightly attached to the boat blades, thereby guaranteeing the uniformity and stability of processes such as coating.

[0039] However, in actual production, the connector is often not centered relative to the boat. When the connector is not centered, a gap will be created between the silicon wafer and the boat, leading to the deposition of materials such as silicon nitride in the gap, ultimately forming a poor appearance with dot marks. This poor appearance not only affects the aesthetics of the silicon wafer, but more importantly, it negatively impacts the electrical performance of the silicon wafer, reducing its conversion efficiency and thus affecting the performance and reliability of the entire photovoltaic module.

[0040] Currently, the existing technology involves emptying the solar cells from the graphite boat and then transporting the boat to a cleaning room. In the cleaning room, the graphite boat needs to be disassembled to locate and correct any faulty connectors. After correction, the graphite boat must be reassembled and transported back to the production workshop for a series of complex operations, including a discharge test run, before it can be loaded with solar cells for production. The entire correction process is time-consuming, typically taking about 1.5 hours, which not only severely impacts production efficiency but also increases production costs. Furthermore, there is a risk of the graphite boat blades breaking during disassembly and assembly, which could damage equipment, potentially leading to safety accidents and further disrupting normal production.

[0041] Based on this, this application discloses a correction device that can adjust the position of the locking point without disassembling the graphite boat blades, preventing the silicon wafer from not fitting tightly to the boat blades due to the offset of the locking point relative to the boat blades, thereby preventing the occurrence of defective solar cells.

[0042] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0043] Please see Figures 1 to 3 , Figure 1 This is a simplified structural diagram of the graphite boat 200 provided in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of the snap-fit ​​connector 202 provided in the embodiments of this application. Figure 3This is a schematic diagram of the snap-fit ​​component 202 disposed on the boat blade 201 according to an embodiment of this application. This application discloses a correction device 100, which is used to correct the snap-fit ​​component 202 on the boat blade 201 of the graphite boat 200 to a centered position. The snap-fit ​​component 202 includes a first surface 2021 and a second surface 2022 that are mutually opposed along a first direction X. The boat blade 201 includes a third surface 2011 and a fourth surface 2012 that are mutually opposed along the first direction X. The first surface 2021 and the third surface 2011 have the same orientation. The first direction X is the thickness direction of the boat blade 201. The centered position is the position of the snap-fit ​​component 202 when the distance from the first surface 2021 to the third surface 2011 is equal to the distance from the second surface 2022 to the fourth surface 2012.

[0044] Please see Figure 4 , Figure 4 This is one of the structural schematic diagrams of the correction device 100 provided in the embodiments of this application. The correction device 100 includes:

[0045] The first clamping rod 12 and the second clamping rod 22 are rotatably connected;

[0046] The first correction component 3 is disposed at the end of the first clamping rod 12 away from the first gripping handle 11 and is located on the side of the first clamping rod 12 facing the second clamping rod 22. The side of the first correction component 3 facing the second clamping rod 22 is the first abutting surface 3a. The first abutting surface 3a is used to abut against the third surface 2011 of the boat blade 201. The first abutting surface 3a is provided with a first groove 31. The first groove 31 is used to accommodate the snap-fit ​​component 202. The bottom wall of the first groove 31 is used to abut against the first surface 2021 of the snap-fit ​​component 202. There is a first preset distance between the bottom wall of the first groove 31 and the first abutting surface 3a. The first preset distance is the distance from the first surface 2021 to the third surface 2011 when the snap-fit ​​component 202 is in the center position.

[0047] The second correction member 4 is disposed at the end of the second clamping rod 22 away from the second gripping handle 21 and is located on the side of the second clamping rod 22 facing the first clamping rod 12. The second correction member 4 corresponds to the position of the first correction member 3 and is used to abut against the second surface 2022 of the snap-fit ​​member 202.

[0048] It is understood that the correction device includes: a first clamp arm 1 and a second clamp arm 2 hinged in the middle. The first clamp arm 1 includes a first gripping handle 11 and a first clamping rod 12, which are located on both sides of the hinge point. The second clamp arm 2 includes a second gripping handle 21 and a second clamping rod 22, which are located on both sides of the hinge point. When the first gripping handle 11 and the second gripping handle 21 approach each other, the first clamping rod 12 and the second clamping rod 22 approach each other.

[0049] The first clamp arm 1 and the second clamp arm 2 are connected by a hinge, allowing the clamp arms to rotate relative to each other. This enables the clamping and releasing operations of the calibration device 100. The structure is simple and easy to operate, facilitating quick and accurate calibration of the snap-fit ​​component 202 by the operator. The first clamp arm 1 includes a first gripping handle 11 and a first clamping rod 12. The second clamp arm 2 includes a second gripping handle 21 and a second clamping rod 22. The first gripping handle 11 and the first clamping rod 12 are located on both sides of the hinge point, and the second gripping handle 21 and the second clamping rod 22 are also located on both sides of the hinge point. This design conforms to the lever principle. When the first gripping handle 11 and the second gripping handle 21 approach each other, the first clamping rod 12 and the second clamping rod 22 can generate clamping force, ensuring stable and reliable clamping of the snap-fit ​​component 202 and facilitating calibration operations.

[0050] The first correction element 3 is disposed at the end of the first clamping rod 12 away from the first gripping handle 11 and is located on the side of the first clamping rod 12 facing the second clamping rod 22. This arrangement allows the first correction element 3 to directly abut against the third surface 2011 of the boat blade 201, thereby effectively correcting the snap-fit ​​element 202.

[0051] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of the calibration device 100, the snap-fit ​​member 202, and the boat blade 201 provided in this embodiment. The first abutment surface 3a is used to abut against the third surface 2011 of the boat blade 201, ensuring stable contact between the calibration device 100 and the boat blade 201 and improving the accuracy of calibration. The first groove 31 is used to accommodate the snap-fit ​​member 202, so that the snap-fit ​​member 202 can be accurately positioned in the first groove 31, facilitating the centering calibration of the snap-fit ​​member 202. The bottom wall of the first groove 31 abuts against the first surface 2021 of the snap-fit ​​member 202, so that the bottom wall of the first groove 31 can apply a stable supporting force to the snap-fit ​​member 202, ensuring the stability of the snap-fit ​​member 202 during the calibration process.

[0052] The first preset distance, i.e. the depth of the first groove 31, is set as the distance from the first surface 2021 to the third surface 2011 when the snap-fit ​​202 is in the center position. When the snap-fit ​​202 is in the first groove 31 and the first surface 2021 of the snap-fit ​​202 abuts against the bottom wall of the first groove 31, the first correction member 3 or the second correction member 4 can push the snap-fit ​​202 to the center position without additional measurement and adjustment, thus improving the correction efficiency and accuracy.

[0053] The second correction component 4 corresponds to the position of the first correction component 3, ensuring that when the snap-fit ​​component 202 is corrected, both sides of the snap-fit ​​component 202 can be supported and corrected at the same time, so that the snap-fit ​​component 202 remains balanced in the first direction X, avoiding tilting or displacement caused by unilateral force, further improving the accuracy and stability of the correction, and ensuring that the corrected snap-fit ​​component 202 can be in the center position.

[0054] The second correction member 4 abuts against the second surface 2022 of the snap-fit ​​member 202, applying a reverse supporting force to the snap-fit ​​member 202. Together with the first correction member 3, it keeps the snap-fit ​​member 202 stable in the central position, preventing the snap-fit ​​member 202 from shifting again due to vibration or other external forces during the production process, thus ensuring the stability of the snap-fit ​​member 202 during the production process and the consistency of silicon wafer quality.

[0055] Thus, the correction device 100 provided in this application embodiment can maintain the balance of the snap-fit ​​member 202 in the first direction X and fix it in a central position on the boat blade 201 through the contact relationship between the first contact surface 3a and the third surface 2011, the contact between the first groove 31 and the first surface 2021, and the contact relationship between the second correction member 4 and the second surface 2022. This allows for adjustment of the snap-fit ​​member 202's position without disassembling the boat blade 201, ensuring the relative position between the silicon wafer fixed by the snap-fit ​​member 202 and the boat blade 201, preventing gaps between the silicon wafer and the boat blade 201, which could lead to poor appearance due to silicon nitride deposition and dot marks. This saves time in disassembling and installing the graphite boat 200, ensuring production and maintenance efficiency.

[0056] Please see Figure 6 , Figure 6 The second schematic diagram of the structure of the correction device 100 provided in the embodiments of this application shows that in some embodiments, the second correction member 4 is provided with a second groove 41 on the side facing the first clamping rod 12. The second groove 41 is used to accommodate the snap-fit ​​member 202, and the bottom wall of the second groove 41 is used to abut against the second surface 2022 of the snap-fit ​​member 202.

[0057] It is understandable that the design of the second groove 41 provides a space for the snap-fit ​​202, so that the snap-fit ​​202 can be stably placed on the second calibration piece 4 during calibration, avoiding the snap-fit ​​202 from shaking or shifting due to external force during the calibration process, thereby ensuring the accuracy and stability of the calibration operation.

[0058] The second groove 41 cooperates with the first groove 31 of the first corrector 3 to jointly constrain and position the two sides of the snap-fit ​​202. When the snap-fit ​​202 is simultaneously accommodated by the first groove 31 and the second groove 41, the position of the snap-fit ​​202 can be controlled more precisely, keeping the snap-fit ​​202 balanced in the first direction X, thereby more effectively correcting the snap-fit ​​202 to the centered position and improving the accuracy and reliability of the correction.

[0059] Furthermore, the bottom wall of the second groove 41 abuts against the second surface 2022 of the snap-fit ​​member 202, providing a stable support force for the snap-fit ​​member 202 and preventing displacement of the snap-fit ​​member 202 in the first direction X perpendicular to the boat blade 201. This stable support ensures that the snap-fit ​​member 202 remains in a centered position during the calibration operation, avoiding calibration errors caused by unstable support and further improving the accuracy of calibration.

[0060] When the latching member 202 is pushed into the second groove 41, causing the second surface 2022 to abut against the bottom wall of the second groove 41, it can cooperate with the support of the first groove 31 on the first surface 2021 of the latching member 202, so that the position of the latching member 202 in the first direction X is precisely defined. In this way, the distance from the first surface 2021 of the latching member 202 to the third surface 2011 of the boat blade 201 and the distance from the second surface 2022 to the fourth surface 2012 of the boat blade 201 can be automatically equalized, thereby accurately correcting the latching member 202 to the centered position, effectively solving the production quality problem caused by the misalignment of the latching member 202, and improving the production quality and appearance quality of the battery cells.

[0061] Please see Figure 5 In some embodiments, the depth of the second groove 41 along the first direction X is less than the distance from the second surface 2022 to the fourth surface 2012 when the snap-fit ​​202 is in the centered position.

[0062] During the calibration of the snap-fit ​​component 202, because the second groove 41 is relatively shallow, when the first calibrator 3 and the second calibrator 4 approach each other to calibrate the snap-fit ​​component 202, the side of the second calibrator 4 facing the first calibrator 3 (i.e., the side where the second groove 41 is located) will not come into contact with the fourth surface 2012 of the boat blade 201. This effectively avoids damage to the boat blade 201 that may be caused by the second calibrator 4 coming into contact with the boat blade 201, protecting the integrity and surface quality of the boat blade 201, extending the service life of the boat blade 201, and also ensuring the continuity and stability of production, avoiding production interruptions and increased maintenance costs caused by damage to the boat blade 201.

[0063] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the cross-sectional area of ​​the first groove 31 along the first direction X is greater than the maximum cross-sectional area of ​​the snap fastener 202 along the first direction X; the cross-sectional area of ​​the second groove 41 along the first direction X is greater than the maximum cross-sectional area of ​​the snap fastener 202 along the first direction X.

[0064] It is understandable that because the cross-sectional area of ​​the first groove 31 perpendicular to the first direction X is larger than the maximum cross-sectional area of ​​the latching member 202 perpendicular to the first direction X, the latching member 202 can be accommodated within the first groove 31. During the calibration operation, the latching member 202 can be smoothly pushed into the first groove 31 without being obstructed by the small cross-sectional area of ​​the groove, thereby improving the convenience and efficiency of the calibration operation. At the same time, the larger cross-sectional area also provides a more stable positioning space for the latching member 202, ensuring that the latching member 202 can maintain a stable position within the first groove 31, avoiding problems such as deformation or positional displacement of the latching member 202 due to insufficient groove space, which is beneficial to improving the accuracy of calibration.

[0065] Similarly, the cross-sectional area of ​​the second groove 41 perpendicular to the first direction X is larger than the maximum cross-sectional area of ​​the snap-fit ​​202 perpendicular to the first direction X, allowing the snap-fit ​​202 to enter the second groove 41 and be stably accommodated. When the snap-fit ​​202 is aligned with the first groove 31, the second groove 41 provides sufficient space for the snap-fit ​​202, enabling it to be stably positioned on one side of the second alignment member 4. Working together with the first groove 31, it ensures that the snap-fit ​​202 remains balanced and stable in the thickness direction, thereby more accurately aligning the snap-fit ​​202 to the center position and improving the alignment effect and quality.

[0066] Furthermore, if the cross-sectional areas of the first groove 31 and the second groove 41 are too small, the snap-fit ​​202 may generate significant friction with the sidewalls of the first groove 31 or the second groove 41 during the insertion process, and may even be deformed by compression, thereby damaging the snap-fit ​​202 and affecting its performance and service life. A larger cross-sectional area, on the other hand, can effectively reduce this friction and compression, lower the risk of damage to the snap-fit ​​202 during the receiving and alignment process, ensure the integrity and reliability of the snap-fit ​​202, and thus guarantee its normal functioning in subsequent production processes.

[0067] Please see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the first clamp arm 1 provided in an embodiment of this application. Figure 8This is a schematic diagram of the structure of the second clamping arm 2 provided in the embodiments of this application. In some embodiments, the first clamping rod 12 is provided with a first limiting part 5, and the second clamping rod 22 is provided with a second limiting part 6. When the first clamping rod 12 and the second clamping rod 22 approach each other, the first limiting part 5 and the second limiting part 6 abut against the first correcting member 3 and the second correcting member 4 before they abut against each other. When the first limiting part 5 and the second limiting part 6 abut against each other, the distance between the first correcting member 3 and the second correcting member 4 is greater than the thickness of the boat blade 201.

[0068] As the first clamping rod 12 and the second clamping rod 22 approach each other, the first limiting part 5 and the second limiting part 6 abut against the first straightening member 3 and the second straightening member 4 before they do. When the first limiting part 5 and the second limiting part 6 abut against each other, a certain distance is still maintained between the first straightening member 3 and the second straightening member 4. This distance is greater than the thickness of the boat blade 201, thereby effectively preventing the first straightening member 3 and the second straightening member 4 from directly colliding with or being excessively squeezed against the boat blade 201, preventing damage to the boat blade 201, ensuring the integrity and surface quality of the boat blade 201, and extending the service life of the boat blade 201.

[0069] Furthermore, the contact between the first limiting part 5 and the second limiting part 6 provides a stable limiting point for the calibration operation, ensuring that the relative positions of the first clamping rod 12 and the second clamping rod 22 remain stable after contact. This guarantees that the distance between the first calibrating member 3 and the second calibrating member 4 will not change unexpectedly during subsequent calibration. This stability helps to precisely control the calibration force, avoiding over-calibration or calibration position deviation caused by the clamping rods getting too close, improving the accuracy and reliability of calibration, and ensuring that the snap-fit ​​member 202 can be accurately calibrated to the centered position.

[0070] Optionally, the first limiting part 5 and the second limiting part 6 can be respectively configured as limiting protrusions, limiting surfaces or limiting grooves, etc., which can realize that when the first clamping rod 12 and the second clamping rod 22 approach each other, the first limiting part 5 and the second limiting part 6 abut against the first correcting member 3 and the second correcting member 4.

[0071] Furthermore, setting the limiting part as a limiting protrusion can provide a clear limiting point when the clamping rods approach each other. Setting the limiting part on the clamping rod and making it a limiting surface can provide a larger limiting area, allowing the clamping rods to stop moving within a relatively stable range when they approach each other; the limiting surface can be flat or curved. Setting the limiting part as a limiting groove can form a limiting space with the opposite limiting part when the clamping rods approach each other, causing the clamping rods to stop moving within this space.

[0072] Please see Figure 7In some embodiments, the first limiting part 5 is a limiting protrusion, the first limiting part 5 is disposed on the side of the first clamping rod 12 facing the second clamping rod 22, and the first limiting part 5 is disposed at the end of the first clamping rod 12 near the first gripping handle 11.

[0073] Specifically, the first limiting part 5 is designed as a limiting protrusion, making its structure clearer and more specific. The limiting protrusion has a certain shape and size, which can form a clear limiting point or limiting surface in space, facilitating its cooperation with the second limiting part 6 to achieve a precise limiting function.

[0074] Furthermore, the limiting protrusion is positioned on the side of the first clamping rod 12 facing the second clamping rod 22, allowing the first limiting part 5 to directly contact the second limiting part 6 when the clamping rods approach each other, effectively restricting the relative movement of the first clamping rod 12 and the second clamping rod 22. Simultaneously, the limiting protrusion is positioned at the end of the first clamping rod 12 near the first gripping handle 11, a position choice that makes the limiting protrusion easier to trigger during operation. When the operator grips the first gripping handle 11 and brings the first clamping rod 12 and the second clamping rod 22 closer together, the limiting protrusion can contact the second limiting part 6 earlier, thereby timely restricting the movement of the clamping rods and avoiding problems such as damage to the boat blade 201 or correction failure caused by over-clamping.

[0075] Please see Figure 8 In some embodiments, the second limiting part 6 is a limiting protrusion, the second limiting part 6 is disposed on the side of the second clamping rod 22 facing the first clamping rod 12, and the second limiting part 6 is disposed at the end of the second clamping rod 22 near the second grip handle 21.

[0076] Specifically, the second limiting part 6 is designed as a limiting protrusion, corresponding to the structure of the first limiting part 5, so that the first limiting part 5 and the second limiting part 6 are structurally similar, facilitating their cooperation to achieve the limiting function. The shape and size of the limiting protrusion can be designed according to actual needs, so that the second limiting part 6 can match the limiting protrusion of the first limiting part 5, ensuring accurate limiting when the clamping rods are close to each other.

[0077] Furthermore, since the limiting protrusion is located near the end of the grip, the operator can more intuitively feel the feedback force when the limiting protrusion contacts the limiting protrusion of the first limiting part 5 during calibration. This feedback force can serve as an important basis for the operator to judge whether the clamping rod has reached the predetermined position, enabling the operator to control the movement of the clamping rod more accurately and avoid problems such as inaccurate calibration or equipment damage caused by over- or under-clamping, thus improving the convenience and accuracy of operation.

[0078] Please see Figure 4In some embodiments, the first corrector 3 is circular, and the diameter of the first corrector 3 is greater than the width of the first clamping rod 12.

[0079] It can be understood that the width of the first clamping rod 12 is the width of the first clamping rod 12 in the direction perpendicular to the first direction X. Since the diameter of the first straightening member 3 is larger than the width of the first clamping rod 12, the contact area between the first straightening member 3 and the boat blade 201 is relatively large. During the process of straightening the snap-fit ​​member 202, the first straightening member 3 will apply a certain force to the boat blade 201. The larger contact area can disperse this force on the surface of the boat blade 201, avoiding excessive force concentration and causing local damage to the boat blade 201, such as indentations or cracks, thereby effectively protecting the surface integrity of the boat blade 201 and extending the service life of the boat blade 201.

[0080] Furthermore, the circular first alignment member 3, when in contact with the boat blade 201, can more evenly distribute the pressure transmitted from the first clamping rod 12 onto the surface of the boat blade 201. Compared to alignment members of other shapes, the circular structure has no sharp edges and corners, and will not generate excessive pressure peaks in local areas. This makes the boat blade 201 more evenly stressed, reducing the risk of deformation or damage to the boat blade 201 due to excessive local stress, and ensuring the stability and reliability of the boat blade 201 during the production process.

[0081] Please see Figure 6 In some embodiments, along the first direction X, the projected area of ​​the first corrector 3 is greater than the projected area of ​​the second corrector 4.

[0082] It is understandable that, due to the larger projected area of ​​the first correction component 3, it can more effectively disperse the force when in contact with the boat blade 201. During the correction of the snap-fit ​​component 202, the first correction component 3 applies a certain pressure to the boat blade 201. The larger projected area allows this pressure to be distributed more evenly on the surface of the boat blade 201, avoiding excessive local pressure that could damage the boat blade 201, such as causing indentations or cracks. This better protects the integrity and surface quality of the boat blade 201 and extends its service life.

[0083] Furthermore, the larger projected area of ​​the first alignment member 3 allows for more precise control of the position of the snap-fit ​​member 202 during alignment. Because the first alignment member 3 has a larger contact area with the boat blade 201, it can more accurately sense and transmit the positional information of the boat blade 201. This allows for more precise adjustment of the snap-fit ​​member 202 to a centered position during alignment, improving alignment accuracy, reducing production quality problems caused by positional deviations of the snap-fit ​​member 202, and increasing product yield.

[0084] Please see Figure 5 and Figure 7 In some embodiments, the first correction member 3 further includes a connecting part 32 and an abutting part 33 connected to each other. One end of the connecting part 32 is connected to the first clamping rod 12, and the other end of the connecting part 32 is connected to the abutting part 33. Along the first direction X, the projected area of ​​the connecting part 32 is smaller than the projected area of ​​the abutting part 33.

[0085] It is understandable that, since the projected area of ​​the connecting part 32 is smaller than that of the abutting part 33, relatively less material is required for the connecting part 32 when manufacturing the first corrector 3. This helps to save on raw material usage and reduce material costs. In mass production, this material saving will significantly reduce production costs and improve the economic efficiency of the enterprise.

[0086] Furthermore, the connecting part 32 has a small projected area, resulting in a relatively small contact area with the clamping rod during use and less wear. This helps extend the service life of the connecting part 32, reduces the frequency of replacement due to wear, and lowers the maintenance cost of the calibration device 100.
