[0037] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0038] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0040] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0041] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0042] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0043] like Figure 1 and Figure 2 As shown, this application embodiment provides a welding strip clamping mechanism, which includes a support frame 1, a limiting component 2, and a fixing component 3. The support frame 1 has a receiving cavity 11, which extends through the support frame 1 along a first direction Y to receive the welding strip 5. The limiting component 2 includes a limiting groove 21 and moves relative to the support frame 1 along a third direction Z. The fixing component 3 moves relative to the support frame 1 along a third direction Z. A portion of the limiting component 2 extends into the receiving cavity 11 and limits the welding strip 5 through the limiting groove 21. A portion of the fixing component 3 extends into the receiving cavity 11 and abuts against the welding strip 5.

[0044] The welding strip clamping mechanism provided in this embodiment accommodates the welding strip 5 through the receiving cavity 11 provided in the support frame 1. The limiting component 2 has a limiting groove 21 and can move along the third direction Z. Therefore, the limiting groove 21 can move along the third direction Z and abut against the welding strip 5. One side of the welding strip 5 abuts against the inner wall of the receiving cavity 11, and the other side abuts against the limiting groove 21, thereby achieving the positioning effect of the welding strip 5. When the welding strip 5 is positioned and limited in a preset position by the limiting mechanism, the fixing mechanism can also move along the third direction Z and abut against the welding strip 5, simultaneously cooperating with the bottom wall of the receiving cavity 11 to clamp and fix the welding strip 5. The welding strip clamping mechanism can position and fix the welding strip 5, thereby improving the accuracy of subsequent welding of the welding strip 5 and reducing the possibility of welding strip 5 shifting or cross-contamination. Currently, technicians may use a horizontal clamping mechanism to clamp the solder strip 5 from both sides along the horizontal direction. This clamping method may cause the solder strip 5 to deflect, especially when the solder strip 5 is flat. During horizontal clamping, the solder strip 5 may rotate, causing it to tip over during the calendering process, leading to microcracks in the final lamination and short circuits in the film strip, thus affecting the quality of the photovoltaic cells. The solder strip clamping mechanism provided in this application first positions the solder strip 5 along the height direction and then fixes it, which can improve the positional accuracy of the solder strip 5 and reduce the possibility of the solder strip 5 tipping over.

[0045] In one possible implementation, the dimension of the limiting groove 21 gradually decreases along the third direction Z in the second direction X, and the second direction X and the third direction Z are perpendicular to each other.

[0046] When the welding strip 5 is located in the receiving cavity 11, its position may not be in the preset position. In order to facilitate the subsequent connection of the welding strip 5, it is necessary to adjust the welding strip 5 to the preset position in the receiving cavity 11. The dimension of the limiting groove 21 in the second direction X gradually decreases in the third direction Z, that is, away from the welding strip 5. When the limiting groove 21 gradually approaches the welding strip 5 along the third direction Z, its dimension in the second direction X is larger, that is, the opening part is larger. It first contacts the welding strip 5. As the limiting groove 21 moves, it continues until the smaller part in the second direction X inside the limiting groove 21 contacts the welding strip 5 and pushes the welding strip 5 to the preset position, thereby limiting the welding strip 5 and enabling the welding strip 5 to reach the preset position in the receiving cavity 11, which facilitates subsequent accurate positioning processing.

[0047] Optionally, the inner wall of the receiving cavity 11 can extend along the second direction Y, thereby increasing the size of the receiving cavity 11 in the second direction Y. When the welding strip 5 is located inside the receiving cavity 11, the inner wall of the receiving cavity 11 can provide a larger support area for supporting the welding strip 5, improving the stability of the welding strip 5 inside the receiving cavity 11 and reducing the possibility of the welding strip 5 tipping over. The cross-section of the receiving cavity 11 can be rectangular, circular, or elliptical, and the bottom wall of the receiving cavity 11 can be flat or curved, etc., which can be set according to the specific shape of the welding strip 5, so that the welding strip 5 can be adjusted to the preset position by the limiting component 2.

[0048] like Figure 2 As shown, in one possible implementation, the limiting groove 21 includes a first limiting part 211 and a second limiting part 212, with a preset included angle between the first limiting part 211 and the second limiting part 212, the preset included angle being 30° to 120°, for forming the limiting groove 21.

[0049] The limiting groove 21 is composed of a first limiting part 211 and a second limiting part 212, wherein the first limiting part 211 and the second limiting part 212 have a preset included angle, and the first limiting part 211 and the second limiting part 212 are respectively located on both sides of the preset position of the welding strip 5. When the welding strip 5 deviates from the preset position along the second direction X, the first limiting part 211 and the second limiting part 212 on both sides can contact the welding strip 5, and as the first limiting part 211 and the second limiting part 212 move closer to the welding strip 5 along the third direction Z, the welding strip 5 can be pushed to the preset position.

[0050] Optionally, the first limiting part 211 and the second limiting part 212 can be configured as arc-shaped, making the inner wall of the limiting groove 21 also arc-shaped, thereby facilitating contact between the inner wall of the limiting groove 21 and the welding strip 5. The first limiting part 211 and the second limiting part 212 are rotatably connected relative to each other, enabling adjustment of the included angle and distance between the first limiting part 211 and the second limiting part 212, thereby changing the shape of the limiting groove 21 to accommodate welding strips 5 of different shapes and sizes. The cross-section of the first limiting part 211 and the second limiting part 212 can be semi-circular, rectangular, triangular, or other shapes.

[0051] Optionally, the limiting groove 21 is an integral structure, and the cross-section of the limiting groove 21 is V-shaped or arc-shaped. The opening of the limiting groove 21 is located on the side of the limiting component 2 close to the welding strip 5.

[0052] like Figure 2 As shown, in one possible implementation, the limiting component 2 includes a first driving member 22, the first driving member 22, the first limiting part 211 and the second limiting part 212 are interconnected, and the first driving member 22 is used to drive the limiting groove 21 to move along the third direction Z.

[0053] The first driving component 22 can be a cylinder or a motor, etc. Preferably, the first driving component 22 is a cylinder. The first driving component 22 is connected to the first limiting part 211 and the second limiting part 212, and is used to drive the limiting groove 21 composed of the first limiting part 211 and the second limiting part 212 to move along the third direction Z, thereby acting as a limiting part for the welding strip 5.

[0054] like Figure 2 As shown, in one possible implementation, the fixing component 3 includes a fixing part 31 and a second driving member 32. The fixing part 31 is fixed to the second driving member 32, and the side of the fixing part 31 away from the second driving member 32 is a plane.

[0055] The second driving component 32 can be a motor or a cylinder, etc. Preferably, the first driving component 22 is a cylinder. The second driving component 32 is connected to the fixing part 31 and is used to drive the fixing part 31 to move along the third direction Z. The side of the fixing part 31 away from the second driving component 32, that is, the side close to the welding strip 5, is a plane. The limiting component 2 first limits the welding strip 5, so that the welding strip 5 is located in a preset position in the receiving cavity 11. When the second driving component 32 drives the fixing part 31 to contact the welding strip 5, it can cooperate with the bottom wall of the receiving cavity 11 to clamp the welding strip 5, thereby fixing the welding strip 5 in the preset position. In the fixing process, compared with clamping and fixing the welding strip 5 from both sides in the horizontal direction, it can reduce the possibility of the welding strip 5 shifting or tipping over, and is more suitable for welding strips 5 with rectangular or irregular cross-sections, which facilitates the further processing of the welding strip 5.

[0056] like Figure 1 As shown, in one possible implementation, the limiting component 2 and the fixing component 3 are spaced apart on the support frame 1 along the first direction Y.

[0057] The limiting component 2 and the fixing component 3 are spaced apart along the first direction Y. When the welding strip clamping mechanism clamps the welding strip 5, the limiting component 2 first limits the welding strip 5 so that the welding strip 5 is located in a preset position, and then the fixing component 3 fixes the welding strip 5 located in the preset position.

[0058] In one possible implementation, the welding strip clamping mechanism includes a mounting frame 4, which is fixedly connected to a support frame 1, and a limiting component 2 and a fixing component 3 are mounted on the mounting frame 4.

[0059] Mounting bracket 4 is mounted on top of support bracket 1 along the third direction Z. Mounting bracket 4 can be connected to support bracket 1 via connectors, such as bolts. Mounting bracket 4 is used to mount limiting component 2 and fixing component 3. Parts of limiting component 2 and fixing component 3 can extend into receiving grooves to limit and fix welding strip 5 respectively. Specifically, this can be achieved by providing connecting mounting holes in mounting bracket 4 and support bracket 1. First driving component 22 and second driving component 32 can be mounted on mounting bracket 4 respectively. The limiting groove 21 connected to first driving component 22 and the fixing part 31 connected to second driving component 32 can extend into receiving cavity 11 to limit and fix welding strip 5.

[0060] In one possible implementation, the receiving cavity 11 has a dimension of 9 mm to 11 mm in the second direction X and a dimension of 24 mm to 26 mm in the third direction Z.

[0061] In one possible implementation, the distance from the bottom wall of the limiting groove 21 to the bottom wall of the receiving cavity 11 is 10 mm to 12 mm.

[0062] The dimensions of the receiving cavity 11 and the limiting groove 21 can be set according to the specific dimensions and shape of the welding strip 5, so that the welding strip 5 can be accurately positioned and stably fixed.

[0063] In one possible implementation, the support frame 1 has a plurality of receiving cavities 11 along the second direction X, and the limiting component 2 and the fixing component 3 are disposed corresponding to the receiving cavities 11.

[0064] The support frame 1 has multiple accommodating cavities 11 that can simultaneously accommodate multiple welding strips 5, and the welding strip clamping mechanism includes multiple limiting components 2 and fixing components 3, which can limit and fix the welding strips 5 in the accommodating cavities 11 respectively, thereby improving the processing efficiency of the welding strip clamping mechanism.

[0065] This application provides a method for clamping solder strips, which is used to clamp solder strips 5 by means of a solder strip clamping mechanism. The solder strip clamping mechanism is any of the solder strip clamping mechanisms described above. The method for clamping solder strips includes:

[0066] S1. The limiting component 2 moves along the third direction Z, so that the welding strip 5 is located inside the limiting groove 21, thereby limiting the welding strip 5;

[0067] S2, the fixing component 3 moves along the third direction Z and abuts against the welding strip 5, fixing the welding strip 5.

[0068] First, the position of the welding strip 5 is adjusted using the limiting component 2. Specifically, the limiting component 2 includes a limiting groove 21, which can move along the third direction Z to approach the welding strip 5. The inner wall of the limiting groove 21 contacts the welding strip 5, and the welding strip 5 is located inside the limiting groove 21, so that the welding strip 5, which deviates from the preset position, can be adjusted to the preset position, so that the welding strip 5 can be accurately processed or connected to the battery cell. When the welding strip 5 is in the preset position, the limiting component 2 moves along the third direction Z to abut against the welding strip 5, and cooperates with the inner wall of the receiving cavity 11 where the welding strip 5 is located to clamp the welding strip 5 from both sides in the third direction Z, improving the stability and accuracy of fixing the welding strip 5.

[0069] In one possible implementation, the limiting component 2 includes a first driving member 22, a first limiting part 211, and a second limiting part 212. The step of limiting the welding strip 5 by moving the limiting component 2 along the third direction Z further includes:

[0070] S11, the first driving member 22 drives the limiting groove 21 to move along the third direction Z, and the first limiting part 211 and / or the second limiting part 212 abut against the welding strip 5.

[0071] There is a preset included angle between the first limiting part 211 and the second limiting part 212. When the welding strip 5 is deviated in the second direction X, the first driving member 22 drives the first limiting part 211 and / or the second limiting part 212 to move along the third direction Z and abut against the welding strip 5, thereby pushing the welding strip 5 to the preset position.

[0072] In one possible implementation, the fixing component 3 includes a second driving member 32 and a fixing part 31. The step of fixing the welding strip 5 by moving the fixing component 3 along the third direction Z further includes:

[0073] S12, the second driving member 32 drives the fixing part 31 to move along the third direction Z, and the fixing part 31 and the welding strip 5 abut against each other.

[0074] The fixing part 31 has a plane, and the second driving member 32 drives the fixing part 31 to move in a third direction and cooperate with the inner wall of the receiving cavity to clamp the welding strip, so that the welding strip can be stably fixed in a preset position.

[0075] This application provides a welding strip clamping mechanism and a welding strip clamping method. The welding strip clamping mechanism includes a support frame 1, a limiting component 2, and a fixing component 3. The support frame 1 has a receiving cavity 11, which extends through the support frame 1 along a first direction Y to receive the welding strip 5. The limiting component 2 includes a limiting groove 21 and moves relative to the support frame 1 along a third direction Z. The fixing component 3 moves relative to the support frame 1 along a third direction Z. A portion of the limiting component 2 extends into the receiving cavity 11 and limits the welding strip 5 through the limiting groove 21. A portion of the fixing component 3 extends into the receiving cavity 11 and abuts against the welding strip 5, which can improve the accuracy and stability of fixing the welding strip 5 and reduce the possibility of the welding strip 5 tipping over.
