[0002] In the solar cell welding process, the soldering ribbons need to be arranged at equal intervals at a certain spacing and cut to a certain length. Before cutting, a clamp is needed to clamp the end of the soldering ribbon and pull out a certain length of the soldering ribbon. The current soldering ribbon pulling device usually includes two movable clamps, and the two movable clamps are distributed up and down or left and right. In the actual working process, since the movement of the two movable clamps requires a large space, in order to avoid interference between the clamps, the spacing between the clamps will be larger. This will not only lead to poor structural compactness of the soldering ribbon pulling device and occupy a large space, but is also only suitable for situations where the spacing between the soldering ribbons is large. When the spacing between the soldering ribbons is small, the soldering ribbon cannot be clamped well. Summary of the invention

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference below Figure 1-Figure 7 The specific structure of the welding ribbon drawing device according to the embodiment of the present invention is described.

[0033] The present invention discloses a welding strip wire drawing device, such as Figure 1 As shown, the welding ribbon pulling device of this embodiment includes a fixed plate 1, a movable clamp 2, a movable plate 3 and an elastic member 4. The fixed plate 1 is provided with a plurality of fixed clamps 111 arranged at intervals. There are a plurality of movable clamps 2, each of which can be rotatably arranged on the fixed plate 1, and is arranged one-to-one with the plurality of fixed clamps 111. The movable plate 3 is used to drive the plurality of movable clamps 2 to rotate in a direction away from the fixed clamps 111. The elastic member 4 is arranged between the fixed plate 1 and the movable clamp 2. The elastic member 4 is used to reset the movable clamp 2. Two adjacent elastic members 4 are arranged in parallel and staggered on one end of the fixed plate 1.

[0034] It is understandable that, in the actual clamping process, the movable plate 3 drives the multiple movable clamps 2 to rotate in the direction away from the fixed clamp 111, so that the spacing between the movable clamp 2 and the fixed clamp 111 becomes larger, thereby clamping the welding strip, and then when the movable plate 3 moves in the opposite direction, the elastic member 4 drives the movable clamp 2 to reset, thereby clamping the welding strip between the movable clamp 2 and the fixed clamp 111. The welding strip wire drawing device of this embodiment adopts a combination of dynamic and static methods to achieve the clamping of the welding strip. In the design process, since only one clamp is movable, there is no need to set a large movable space, so that the structure of the entire welding strip wire drawing device is more compact, and the spacing between the two movable clamps 2 can be reduced, so that the welding strip wire drawing device is suitable for the clamping requirements of welding strips with smaller spacing, thereby improving the scope of application of the welding strip wire drawing device. At the same time, two adjacent elastic members 44 are arranged in parallel and staggered on one end of the fixed plate 1, so that the projections of the elastic members 4 that stop on the two adjacent movable clamps 2 along the height direction of the fixed plate 1 can have overlapping parts, thereby making the distance between the two adjacent movable clamps 2 smaller, further improving the structural compactness of the welding ribbon wire pulling device, and reducing the space occupied by the welding ribbon wire pulling device.

[0035] In some embodiments, Figure 2-Figure 3 As shown, the fixed plate 1 is provided with a plurality of abutment structures 112, one end of the elastic member 4 is connected to the movable clamp 2, and the other end abuts against the abutment structure 112. Thus, it is possible to ensure that the elastic member 4 is stably compressed when the movable plate 3 drives the movable clamp 2 to move, so that the elastic member 4 resets the movable clamp 2 when the movable plate 3 moves in the reverse direction.

[0036] In some specific embodiments, Figure 2-Figure 3As shown, the multiple stop structures 112 include multiple upper stop portions 1121 and multiple lower stop portions 1122, and the multiple upper stop portions 1121 and the multiple lower stop portions 1122 are all arranged at intervals along the length direction of the fixed plate 1, and the upper stop portions 1121 and the lower stop portions 1122 are staggered in the length direction and the height direction of the fixed plate 1; the movable clamp 2 includes multiple upper movable clamps 21 and multiple lower movable clamps 22, and the multiple upper movable clamps 21 are arranged corresponding to the multiple upper stop portions 1121, and the multiple lower movable clamps 22 are arranged corresponding to the multiple lower stop portions 1122. It can be understood that, in the present embodiment, the plurality of stop structures 112 include a plurality of upper stop portions 1121 and a plurality of lower stop portions 1122. In the length direction and the height direction of the fixed plate 1, the upper stop portions 1121 and the lower stop portions 1122 are staggered. In this way, the plurality of elastic members 4 can be staggered in the height direction of the fixed plate 1, so that the projections of the adjacent elastic members 4 stopping on the upper movable clamp 21 and the elastic members 4 stopping on the lower movable clamp 22 along the height direction of the fixed plate 1 can overlap, so that the distance between two adjacent upper movable clamps 21 and lower movable clamps 22 is smaller, thereby further improving the structural compactness of the welding ribbon wire pulling device and reducing the space occupied by the welding ribbon wire pulling device.

[0037] In some more specific embodiments, Figure 3 As shown, the upper movable clamp 21 is provided with an upper avoidance recess 211 for avoiding the lower stop portion 1122, and the lower movable clamp 22 is provided with a lower avoidance recess 221 for avoiding the upper stop portion 1121. It can be understood that the additional upper avoidance recess 211 and the lower avoidance recess 221 can make the spacing between the adjacent upper movable clamps 21 and lower movable clamps 22 smaller or even achieve zero spacing between the upper movable clamps 21 and the lower movable clamps 22, further improving the compactness of the structure of the welding ribbon wire drawing device and reducing the space occupied by the welding ribbon wire drawing device.

[0038] In some embodiments, Figure 3-Figure 4 As shown, the fixed clamp 111 includes a root 1111 and a fixed clamp 1112 perpendicular to the root 1111, and a guide structure 1113 is formed on one end of the fixed clamp 1112 away from the root 1111 toward the corner of the movable clamp 2; the movable clamp 2 has a dynamic clamp 203, and the dynamic clamp 203 and the root 1111 are staggered along the thickness direction of the fixed plate 1, and the welding strip is clamped between the dynamic clamp 203 and the fixed clamp 1112. It can be understood that the welding strip is clamped between the dynamic clamp 203 and the fixed clamp 1112, so that the welding strip drawing device of this embodiment can stably clamp the welding strip, and the guide structure 1113 is formed on one end of the fixed clamp 1112 away from the root 1111 toward the corner of the movable clamp 2, and the inclined surface formed by the guide structure 1113 is conducive to guiding the welding strip in the process of clamping the welding strip, thereby ensuring that the welding strip drawing device of this embodiment can stably clamp the welding strip.

[0039] In some embodiments, Figure 1 As shown, the welding strip wire drawing device also includes a driving member 5, and the power output end of the driving member 5 is connected to the movable plate 3 to drive the movable plate 3 to rotate along the length direction of the fixed plate 1. It can be understood that the use of the driving member 5 to drive the movable plate 3 to move can achieve the automation of the entire welding strip wire drawing device, thereby improving work efficiency. In the embodiment of the present invention, the driving member 5 can select any driving structure such as a cylinder, an electric push rod, a motor-driven ball screw, etc. according to actual needs, and the specific type of the driving member 5 is not limited here.

[0040] In some embodiments, Figure 7 As shown, the movable plate 3 is provided with a plurality of drive shafts 31, and each movable clamp 2 is provided with a drive portion 202, and the drive shaft 31 abuts against the drive portion 202. Therefore, during the movement of the movable plate 3, the plurality of drive shafts 31 can simultaneously drive the drive portion 202 to move, so that the movable clamp 2 rotates relative to the fixed plate 1, which can simplify the structure of the movable plate 3 and facilitate processing and manufacturing.

[0041] In some embodiments, Figure 2 As shown, the fixed plate 1 includes a vertical plate 11 and a horizontal plate 12, a plurality of fixed clamps 111 are arranged at one end of the vertical plate 11, the horizontal plate 12 is connected to the vertical plate 11, the horizontal plate 12 is connected to the vertical plate 11, a slide rail 10 and a slider 20 slidably arranged on the slide rail 10 are arranged on the horizontal plate 12, and the movable plate is arranged on the horizontal plate 12 through the slide rail 10 and the slider (20). It can be understood that the vertical plate 11 is used to install the movable clamp 2, and the horizontal plate 12 is used to support the movable plate 3, and the movement direction of the movable plate 3 is limited by the cooperation of the guide slide rail 10 and the guide slider 20, so as to ensure that the movable plate 3 can stably drive the movable clamp 2 to rotate.

[0042] In some specific embodiments, Figure 2 As shown, the horizontal plate 12 includes a fixed horizontal portion 121 and an adjustable horizontal portion 122. The fixed horizontal portion 121 is provided with an adjustment seat 6, and the adjustment seat 6 is provided with an adjustment member 7. The adjustable horizontal portion 122 is connected to the vertical plate 11, and one end of the adjustable horizontal portion 122 abuts against the adjustment member 7. The fixed horizontal portion 121 is provided with an adjustment long hole, and the fixed horizontal portion 121 is connected to the adjustable horizontal portion 122 by matching a connector that is inserted into the adjustment long hole. It can be understood that in the actual working process, the position of the emergence end of the welding strip may be different. In this embodiment, since one end of the adjustable horizontal portion 122 abuts against the adjustment member 7, the position of the adjustable horizontal portion 122 relative to the fixed horizontal portion 121 can be adjusted by operating the adjustment member 7 to achieve the adjustment of the position of the vertical plate 11, so as to ensure that the fixed clamp 111 can be aligned with the emergence end of the welding strip, thereby ensuring that the welding strip drawing device of this embodiment stably clamps the welding strip.

[0043] It should be noted that in the embodiment of the present invention, the adjusting member 7 can be a structure such as a bolt, a stud, or a pin according to actual needs, and the type of the adjusting member 7 is not specifically limited here.
