In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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.

[0031] The following describes a welding ribbon clamping device 1 for a stringer according to an embodiment of the utility model with reference to the accompanying drawings.

[0032] like Figure 1-Figure 8 As shown, the solder ribbon clamping device 1 for a stringer according to an embodiment of the utility model includes a base plate 10 , a pressing assembly 20 and a clamping assembly 30 .

[0033] The pressing assembly 20 is disposed on the substrate 10 and is suitable for pressing the soldering ribbon onto the cutting platform.

[0034] The clamping assembly 30 is disposed on the substrate 10 and is suitable for clamping and releasing the soldering ribbon.

[0035] Specifically, the substrate 10 can be connected to the moving device through the connecting frame 11, and the moving device can be a welding strip transporting overhead crane. The clamping assembly 30 has a clamping state for clamping the welding strip and an open state for releasing the welding strip.

[0036] Reference below Figure 1-Figure 8 The working process of the welding ribbon clamping device 1 for a stringer according to an embodiment of the utility model is described.

[0037] The welding strip transport crane is translated to above the welding strip (the clamping assembly 30 is currently in the open state), the welding strip transport crane is lowered, so that the pressing assembly 20 presses the welding strip on the cutting platform, and at the same time the clamping assembly 30 switches to the clamping state to clamp the welding strip;

[0038] The solder strip cutter starts to cut the solder strip, and the excess solder strip remains clamped by the clamping assembly 30 after cutting.

[0039] The welding strip transport crane rises, the pressing assembly 20 is separated from the welding strip, and at the same time the clamping assembly 30 maintains the clamping state and carries the clamped broken welding strip upward;

[0040] The welding strip transport crane is moved horizontally to above the broken welding strip placement slot and then descends, and the clamping assembly 30 is switched to a released state to place the broken welding strip in the broken welding strip placement slot.

[0041] According to the solder tape clamping device 1 of the stringer welder embodiment of the utility model, by setting a clamping component 30, the clamping component 30 can be used to clamp the excess part of the solder tape that needs to be cut off. On the one hand, the clamping of the clamping component 30 can be used to realize the positioning of the solder tape, improve the position accuracy during cutting, and improve the accuracy of cutting. On the other hand, the excess broken solder tape after cutting can be kept clamped by the clamping component 30, and the broken solder tape can be placed in the broken solder tape groove by moving the solder tape clamping device 1 of the stringer welder to avoid the broken solder tape being left on the cutting platform. Compared with the technical solution of cleaning with a brush in the related art, since the broken solder tape is always clamped by the clamping component 30 before and after cutting, it will not be left on the cutting platform, which can avoid the remaining broken solder tape causing deviation in subsequent solder tape positioning, and avoid the subsequent solder tape being bent and dropped, and jamming during cutting.

[0042] Furthermore, by providing a clamping assembly 20, the soldering ribbon can be pressed onto the cutting platform using the clamping assembly 20 during the cutting process to avoid displacement of the soldering ribbon on the cutting platform due to vibration during the cutting process, thereby improving the positioning accuracy of the soldering ribbon and ensuring reliable contact between the soldering ribbon and the wiring points of the battery cell, thereby avoiding problems such as cold solder joints.

[0043] Therefore, the solder ribbon clamping device 1 for a stringer according to the embodiment of the utility model has the advantages of reliable positioning, avoiding residual broken solder ribbons, and avoiding cold solder joints.

[0044] The following describes a welding ribbon clamping device 1 for a stringer according to a specific embodiment of the utility model with reference to the accompanying drawings.

[0045] In some specific embodiments of the present invention, Figure 1-Figure 8 As shown, the solder ribbon clamping device 1 for a stringer according to an embodiment of the utility model comprises a base plate 10 , a plurality of pressing assemblies 20 and a plurality of clamping assemblies 30 .

[0046] Specifically, Figure 1-Figure 8 As shown, the pressing assembly 20 includes a plurality of pressing devices 22 arranged at intervals along the first direction, each of which is suitable for pressing the welding strip on the cutting platform, and the clamping assembly 30 includes a plurality of clamping devices 33 arranged at intervals along the first direction (the up and down directions are shown by arrows in the figure and are only for the convenience of description, not for the actual setting direction, and the first direction and the second direction are both perpendicular to the up and down directions), and each clamping device 33 is suitable for clamping and releasing the welding strip. In this way, multiple welding strips can be clamped and pressed at the same time, thereby improving the cutting efficiency of the welding strip.

[0047] Advantageously, if Figure 1 and Figure 2 As shown, there are multiple pressing assemblies 20 and multiple clamping assemblies 30, and multiple pressing assemblies 20 and multiple clamping assemblies 30 are alternately arranged on the substrate 10 in the second direction. This makes it easy to cut the solder strips of multiple battery cells at the same time, further improving the cutting efficiency of the solder strips.

[0048] Specifically, the cutting tool can pass between each adjacent pressing assembly 20 and clamping assembly 30 to cut the welding ribbon.

[0049] Alternatively, if Figure 1 and Figure 2 As shown, the first direction is the width direction of the substrate 10, and the second direction is the length direction of the substrate 10. This can facilitate the arrangement of the pressing assembly 20 and the clamping assembly 30 on the substrate 10, making the structure of the stringer welding ribbon clamping device 1 more compact.

[0050] Figure 3 and Figure 4 The figure shows a welding ribbon clamping device 1 for a string welding machine according to some examples of the utility model. Figure 3 and Figure 4 As shown, the pressing assembly 20 further includes a pressing bracket 21, which is disposed on the lower surface of the substrate 10. The pressing device 22 includes a pressing member 221 and an elastic member 222. The pressing member 221 is disposed on the pressing bracket 21 so as to be movable up and down, and the elastic member 222 always drives the pressing member 221 to move downward. In this way, the pressing member 221 can be used to press the solder strip, and the elastic member 222 can be used to buffer the pressing force of the pressing member 221, so as to avoid excessive pressing force and damage to the solder strip.

[0051] Specifically, Figure 3 and Figure 4As shown, the clamping bracket 21 is provided with a plurality of through holes 211, and the clamping member 221 includes a clamping shaft 2211 and a clamping head 2212, wherein the plurality of clamping shafts 2211 respectively pass through the plurality of through holes 211, and the clamping head 2212 is connected to the lower end of the clamping shaft 2211, and the diameter of the clamping head 2212 is greater than the diameter of the clamping shaft 2211, and the elastic member 222 is a compression spring, which is sleeved outside the clamping shaft 2211 and compressed between the compression head 2212 and the clamping bracket 21. This facilitates the arrangement of the clamping member 221 and the elastic member 222.

[0052] More specifically, Figure 3 and Figure 4 As shown, a clamping groove is provided at the upper end of the clamping shaft, and the clamping groove is matched with a clamping ring, and the clamping ring is suitable for stopping on the clamping bracket to prevent the clamping member from being separated from the through hole.

[0053] Figure 5-Figure 8 The figure shows a welding ribbon clamping device 1 for a string welding machine according to some examples of the utility model. Figure 5-Figure 8 As shown, the clamping assembly 30 also includes a clamping bracket 31 and a driving device 32. The clamping bracket 31 is arranged on the lower surface of the substrate 10. The clamping device 33 includes a movable clamping block 331 and a fixed clamping block 332. The fixed clamping block 332 is arranged on the clamping bracket 31. The movable clamping block 331 is movably arranged on the clamping bracket 31, and the movable clamping block 331 is transmission-connected with the driving device 32. Specifically, when the clamping device 33 is in the clamping state, the movable clamping block 331 and the fixed clamping block 332 clamp the welding strip together, and when the driving device 32 is in the open state, the movable clamping block 331 and the fixed clamping block 332 release the welding strip. In this way, the driving device 32 can drive multiple movable clamping blocks 331 to move so that the movable clamping blocks 331 and the fixed clamping blocks 332 clamp or release the welding strip.

[0054] Specifically, Figure 5-Figure 8 As shown, the clamping assembly 30 also includes a sliding link 34, which is slidably disposed on the clamping bracket 31, the driving device 32 is connected to the sliding link 34, the upper end of the movable clamp block 331 is pivotally connected to the sliding link 34, and the middle part of the movable clamp block 331 is pivotally connected to the fixed clamp block 332. Specifically, when the clamping device 33 is in the clamping state, the lower end of the movable clamp block 331 is close to the lower end of the fixed clamp block 332 to clamp the welding strip, and when the clamping device 33 is in the open state, the lower end of the movable clamp block 331 is away from the lower end of the fixed clamp block 332 to release the welding strip. In this way, the driving device 32 can drive the sliding link 34 to drive the multiple movable clamp blocks 331 to rotate by sliding the sliding link 34, thereby realizing the relative rotation of the movable clamp block 331 and the fixed clamp block 332, and realizing the clamping or release of the clamping device 33.

[0055] More specifically, Figure 8As shown, the fixed clamp block 332 is provided with an avoidance groove 3320, the middle part of the movable clamp block 331 has a lug 3310, the lug 3310 is matched in the avoidance groove 3320, the lug 3310 is provided with an axial hole 3311, the fixed clamp block 332 is provided with a mounting hole 3321 connected with the avoidance groove 3320, and the movable clamp block 331 and the fixed clamp block 332 are pivotally connected through a rotating shaft matched in the axial hole 3311 and the mounting hole 3321. In this way, the movable clamp block 331 and the fixed clamp block 332 can be pivotally connected, and the structure of the clamping device 33 can be made more compact.

[0056] Specifically, the driving device 32 is a cylinder, which can be used to control the driving force to ensure the clamping force.

[0057] The lower end of the movable clamping block 331 may be provided with a clamping hook, and the lower end of the fixed clamping block 332 may be provided with a clamping groove, so as to facilitate clamping the welding strip.

[0062] The solder strip cutter starts to cut the solder strip, and the excess solder strip remains clamped by the clamping assembly 30 after cutting.

[0063] The welding strip transport crane rises, the pressing assembly 20 is separated from the welding strip, and at the same time the clamping assembly 30 maintains the clamping state and carries the clamped broken welding strip upward;
