Description

Technical Field

[0001] The present application relates to the field of production equipment for photovoltaic cell modules, and more particularly to a solder tape control mechanism and a cell welding device. Background Art

[0002] In a traditional cell welding device, a solder tape group is towed and laid on a welding carrier mechanism or a cell by a solder tape towing mechanism. To prevent the solder tape group from sagging and shifting, a lifting and guiding mechanism is usually provided on the towing path of the solder tape to implement the lifting and guiding of the solder tape group. In addition, to ensure that the solder tape group is accurately laid on the welding carrier mechanism or the cell, a tail clip is required at the end of the welding carrier mechanism. When the solder tape towing mechanism lays the solder tape group, the tail clip holds the tail end (i.e., the free end that is not clamped) of the solder tape group, so that the solder tape group is straightened and then laid on the welding carrier mechanism or the cell.

[0003] It can be seen that in order to realize the guiding and straightening of the solder tape group, a traditional cell welding device needs to separately provide a lifting and guiding mechanism and a tail clip, which increases the complexity and cost of the equipment. Summary of the Utility Model

[0004] To solve the above technical problems, the present application provides a solder tape control mechanism, which adopts the following technical solutions:

[0005] A solder tape control mechanism includes a base, a first moving plate, a second moving plate and a driving part, wherein:

[0006] The first moving plate is slidably installed on the base. Along a first horizontal direction, n first chucks are arranged on the first moving plate. The second moving plate is slidably installed on the base. Along the first horizontal direction, n second chucks are arranged on the second moving plate. The second chucks are arranged in pairs with the first chucks. A pair of first and second chucks constitutes a chuck assembly. Each chuck assembly is used to clamp and hold a solder tape. The solder tape extends along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction;

[0007] The driving part is arranged on the base and is configured to drive the first moving plate and the second moving plate to move along the first horizontal direction, so as to drive each first chuck and the paired second chuck to be semi-closed or closed when approaching each other. When the first chuck and the paired second chuck are semi-closed, the first chuck and the paired second chuck hold the solder tape, and the solder tape can move along the second horizontal direction between the first chuck and the paired second chuck. When the first chuck and the paired second chuck are closed, the first chuck and the paired second chuck clamp the solder tape.

[0008] The welding strip control mechanism provided by the present application, each of which has a chuck assembly capable of clamping and tightening the welding strip. In particular, when the chuck assembly clamps the welding strip, the welding strip can move in the chuck assembly. The welding strip control mechanism provided by the present application is suitable for guiding and straightening the welding strip group in the battery cell welding application, and the specific working process is as follows: when the welding strip traction mechanism pulls the welding strip group toward the welding bearing mechanism, the first chuck and the second chuck of each chuck assembly are controlled to be half closed, so that each chuck assembly clamps a welding strip in the welding strip group to guide the welding strip; when the welding strip traction mechanism lays the welding strip group on the welding bearing mechanism or the battery cell on the welding bearing mechanism, the first chuck and the second chuck of each chuck assembly are controlled to be closed, so that each chuck assembly clamps the tail end of the corresponding welding strip to cooperate with the welding strip traction mechanism to straighten the welding strip, and finally ensure that the welding strip traction mechanism accurately lays the welding strip group to the target position. Therefore, the welding strip control mechanism provided by the present application integrates the functions of the traditional lifting and guiding mechanism and the tail clamp, and has a compact structure and low cost.

[0009] In some embodiments, the driving unit includes a first driving unit and a second driving unit, wherein the movable component of the first driving unit is connected to the first movable plate, and the movable component of the second driving unit is connected to the second movable plate; the first driving unit and the second driving unit are configured to synchronously drive the first movable plate and the second movable plate to approach or move away from each other along a first horizontal direction.

[0010] A driving unit with a simple structure is provided, which drives the first moving plate and the second moving plate to move closer to or farther from each other along the first horizontal direction through the cooperation of the first driving unit and the second driving unit, so that the driving control is more convenient.

[0011] In some embodiments, the welding ribbon control mechanism also includes a limiting portion arranged on the base, and a first adapter assembly and a second adapter assembly, wherein: the first adapter assembly is fixedly connected to the first movable plate, and the second adapter assembly is fixedly connected to the second movable plate; the limiting portion is configured to limit the moving distance between the first adapter assembly and the second adapter assembly, so that each first chuck is semi-closed or closed with a pair of second chucks.

[0012] By limiting the moving distance between the first adapter assembly and the second adapter assembly through the limiting part, the distance between the first chuck and the paired second chucks when they are close to each other can be adjusted, thereby achieving semi-closed or closed control of the first chuck and the paired second chucks.

[0013] In some embodiments, when the first adapter assembly and the second adapter assembly approach each other, each first chuck and the paired second chucks are semi-closed or closed, wherein: the limiting part includes a third driving member and a limiting block, wherein the third driving member is mounted on the base, and the limiting block is slidably connected to the base in the second horizontal direction and is connected to the driving end of the third driving member; the limiting block is provided with a first limiting section and a second limiting section in the second horizontal direction, and the width of the first limiting section in the first horizontal direction is smaller than the width of the second limiting section in the first horizontal direction; the third driving member is used to drive the limiting block to move in the second horizontal direction so that the first limiting section or the second limiting section enters between the first adapter assembly and the second adapter assembly.

[0014] When the third driving member drives the limiting block to move in the second horizontal direction to the first position, the first limiting section of the limiting block enters between the first adapter assembly and the second adapter assembly. Thus, when the first adapter assembly and the second adapter assembly approach each other, the first adapter assembly and the second adapter assembly finally abut against the two side walls of the first limiting section respectively, so that the first chuck and the paired second chucks are completely closed; when the third driving member drives the limiting block to move in the second horizontal direction to the second position, the second limiting section of the limiting block enters between the first adapter assembly and the second adapter assembly. Thus, when the first adapter assembly and the second adapter assembly approach each other, the first adapter assembly and the second adapter assembly finally abut against the two side walls of the second limiting section respectively, so that the first chuck and the paired second chucks are semi-closed.

[0015] In some embodiments, when the first adapter assembly and the second adapter assembly move away from each other, each first chuck and the paired second chucks are semi-closed or closed, wherein: the limiting part includes a third driving member and a limiting block, wherein the third driving member is mounted on the base, and the limiting block is slidably connected to the base in the second horizontal direction and is connected to the driving end of the third driving member; the limiting block is provided with a limiting groove facing the first adapter assembly and the second adapter assembly, and the limiting groove is a C-shaped groove or a V-shaped groove. The third driving member is used to drive the limiting block to move in the second horizontal direction so that the first adapter assembly and the second adapter assembly enter the limiting groove.

[0016] When the third driving member drives the limiting block to move so that the first adapter assembly and the second adapter assembly enter the wider part of the limiting groove, the first adapter assembly and the second adapter assembly finally abut against the opposite inner walls of the wider part of the limiting groove, so that the first chuck and the paired second chucks are closed. When the third driving member drives the limiting block to move so that the first adapter assembly and the second adapter assembly enter the narrower part of the limiting groove, the first adapter assembly and the second adapter assembly finally abut against the opposite inner walls of the narrower part of the limiting groove, so that the first chuck and the paired second chucks are semi-closed.

[0017] In some embodiments, the first transfer assembly includes a first transfer block and a first pressing block. The first transfer block is fixedly connected to the first moving plate, and the first pressing block is installed at the end of the first transfer block. The second transfer assembly includes a second transfer block and a second pressing block. The second transfer block is fixedly connected to the second moving plate, and the second pressing block is installed at the end of the second transfer block. The first pressing block and the second pressing block are respectively used to abut against opposite sides of the limiting block, or the first pressing block and the second pressing block are respectively used to abut against opposite sides of the limiting groove.

[0018] A first transfer assembly and a second transfer assembly with simple structures and convenient installation are provided.

[0019] In some embodiments, the first moving plate is horizontally arranged, the first chuck is arranged on the first moving plate and extends along a second horizontal direction, and the first end of the first chuck extends out of the first moving plate. The second moving plate is located below or on the side of the first moving plate, the second chuck is arranged vertically and extends upward out of the second moving plate, and the second chuck cooperates with the first end of the first chuck to clamp or grip the welding tape.

[0020] On the premise of ensuring that the second chuck and the first chuck can smoothly clamp or grip the welding tape, the first moving plate can also support the welding tape to prevent the welding tape from sagging during traction or laying.

[0021] In some embodiments, the welding tape control mechanism further includes n + 1 alignment blocks arranged at intervals on the first moving plate along a first horizontal direction, and a first chuck is correspondingly arranged between adjacent two alignment blocks. Among them: the middle of the i-th first chuck is rotatably connected to the first moving plate, the second end of the i-th first chuck is located between the i-th alignment block and the (i + 1)-th alignment block, and a spring is arranged between the second end of the i-th first chuck and the (i + 1)-th alignment block. The spring is used to elastically press the second end of the i-th first chuck against the i-th alignment block; 1 ≤ i ≤ n.

[0022] Since the middle of the i-th first chuck is rotatably connected to the first moving plate, and the second end of the i-th first chuck is elastically pressed against the i-th alignment block, when the i-th first chuck and the paired i-th second chuck are closed, the i-th first chuck can generate adaptive deflection when contacting the welding tape to adapt to the size differences between different welding tapes, thereby eliminating gaps and ensuring that the first end of the i-th first chuck and the paired i-th second chuck can clamp the welding tape. That is, by setting the alignment blocks and the springs, the first end of the first chuck and the paired second chuck can firmly clamp welding tapes with different thicknesses, thereby improving the compatibility of the application.

[0023] In some embodiments, the second chuck has an L-shaped structure. The second chuck includes a vertical portion and a horizontal portion. The vertical portion is used to cooperate with the first end of the first chuck to clamp or hold the welding tape, and the horizontal portion is used to limit the welding tape from above. Alternatively, the first end of the first chuck has an L-shaped structure. The first end of the first chuck includes a vertical portion and a horizontal portion. The vertical portion is used to cooperate with the second chuck to clamp or hold the welding tape, and the horizontal portion is used to limit the welding tape from above.

[0024] Ensure that the first end of the first chuck and the paired second chucks can stably clamp or hold the welding tape, preventing the welding tape from slipping out between the first end of the first chuck and the paired second chucks.

[0025] In some embodiments, n second chucks are integrally formed at the upper end of the clamping plate, and the clamping plate is fixed to the second moving plate in the vertical direction.

[0026] It facilitates the preparation, forming, and unified installation of the n second chucks.

[0027] The present application also provides a battery cell welding device, which includes a welding tape traction mechanism, a battery cell loading mechanism, a welding carrying mechanism, a welding mechanism, and the welding tape control mechanism described in any one of the above. Among them:

[0028] The welding carrying mechanism is configured to reciprocally translate in the horizontal direction. An unloading station and a welding station are sequentially arranged on the moving path of the welding carrying mechanism.

[0029] The welding tape traction mechanism is used to traction the first welding tape group towards the welding carrying mechanism located at the unloading station, and to lay the first welding tape group on the welding carrying mechanism. The battery cell loading mechanism is used to stack battery cells on the first welding tape group. The welding tape traction mechanism is also used to traction the second welding tape group towards the welding carrying mechanism, and to lay the second welding tape group on the battery cells.

[0030] The welding tape control mechanism is located on the traction path of the welding tape group and is close to the unloading station. The welding tape control mechanism is configured to clamp the first welding tape group or the second welding tape group when the welding tape traction mechanism tractions the first welding tape group or the second welding tape group, so as to guide the first welding tape group or the second welding tape group. The welding tape control mechanism is also configured to clamp the tail end of the first welding tape group or the second welding tape group when the welding tape traction mechanism lays the first welding tape group or the second welding tape group, so as to straighten the first welding tape group or the second welding tape group.

[0031] The welding mechanism is arranged at the welding station. The welding mechanism is used to weld the first welding tape group and the second welding tape group located on the welding carrying mechanism to the battery cells when the welding carrying mechanism moves to the welding station.

[0032] Through the cooperation of the solder tape control mechanism, the solder tape traction mechanism, the cell placing mechanism, the welding bearing mechanism and the welding mechanism, the cell welding device of the embodiment of the present application can automatically weld the solder tape group to the two surfaces of the cell, thereby realizing the automatic preparation of the replacement cell required for the repair of the battery string and improving the preparation efficiency of the replacement cell. In particular, when the solder tape traction mechanism traction the first solder tape group or the second solder tape group, the solder tape control mechanism clamps and guides the first solder tape group or the second solder tape group. When the solder tape traction mechanism lays the first solder tape group or the second solder tape group, the solder tape control mechanism cooperates with the solder tape traction mechanism to clamp and straighten the first solder tape group or the second solder tape group, and finally ensures that the first solder tape group or the second solder tape group is accurately laid at the target position.

[0059] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0060] As Figures 1 to 3 shown, the weld tape control mechanism 10 in the embodiment of the present application includes a base 1, a first moving plate 2, a second moving plate 3, and a drive part 4, where:

[0061] The first moving plate 2 is slidably mounted on the base 1. Along the first horizontal direction (such as the X-axis direction) on the first moving plate 2, n first chucks 5 are provided. The second moving plate 3 is slidably mounted on the base 1. Along the first horizontal direction on the second moving plate 3, n second chucks 6 are provided. The second chucks 6 are arranged in pairs with the first chucks 5, and a pair of the first chuck 5 and the second chuck 6 constitutes a chuck assembly. Each chuck assembly is used to clamp and hold a solder tape. The solder tape extends along the second horizontal direction (such as the Y-axis direction), and the second horizontal direction is perpendicular to the first horizontal direction.

[0062] The driving part 4 is arranged on the base 1. The driving part 4 is configured to drive the first moving plate 2 and the second moving plate 3 to move along the first horizontal direction, so as to drive each first chuck 5 and the paired second chuck 6 to be semi-closed or closed when approaching each other. Among them, when the first chuck 5 and the paired second chuck 6 are semi-closed, the first chuck 5 and the paired second chuck 6 hold the solder tape, and the solder tape can move along the second horizontal direction between the first chuck 5 and the paired second chuck 6. When the first chuck 5 and the paired second chuck 6 are closed, the first chuck 5 and the paired second chuck 6 clamp the solder tape.

[0063] The solder tape control mechanism in the embodiment of the present application is suitable for guiding and straightening the solder tape group in the application of battery cell welding. The specific working process is as follows:

[0064] When the solder tape traction mechanism traction the solder tape group towards the welding bearing mechanism, control the first chuck 5 and the second chuck 6 of each chuck assembly to be semi-closed, so that each chuck assembly holds a solder tape in the solder tape group to implement the guiding of the solder tape.

[0065] When the solder tape traction mechanism lays the solder tape group on the welding bearing mechanism or the battery cell on the welding bearing mechanism, control the first chuck 5 and the second chuck 6 of each chuck assembly to be closed, so that each chuck assembly clamps the tail end of the corresponding solder tape to cooperate with the solder tape traction mechanism to straighten the solder tape, and finally ensure that the solder tape traction mechanism lays the solder tape group accurately at the target position.

[0066] As Figure 3 shown, optionally, the driving part 4 includes a first driving part 41 and a second driving part 42. Among them, the moving part of the first driving part 41 is connected to the first moving plate 2, and the moving part of the second driving part 42 is connected to the second moving plate 3. The first driving part 41 and the second driving part 42 are configured to synchronously drive the first moving plate 2 and the second moving plate 3 to approach or move away from each other along the first horizontal direction, so as to drive the first chuck 5 and the second chuck 6 to approach or move away from each other.

[0067] As Figure 7 and Figure 9As shown, in some embodiments, when the driving part 4 drives the first moving plate 2 and the second moving plate 3 to approach each other along the first horizontal direction, the first chuck 5 and the second chuck 6 are driven to approach each other. When the driving part 4 drives the first moving plate 2 and the second moving plate 3 to move away from each other along the first horizontal direction, the first chuck 5 and the second chuck 6 are driven to move away from each other.

[0068] As Figure 8 and Figure 10 shown, in other embodiments, when the driving part 4 drives the first moving plate 2 and the second moving plate 3 to move away from each other along the first horizontal direction, the first chuck 5 and the second chuck 6 are driven to approach each other. When the driving part 4 drives the first moving plate 2 and the second moving plate 3 to approach each other along the first horizontal direction, the first chuck 5 and the second chuck 6 are driven to move away from each other.

[0069] Both the first driving part 41 and the second driving part 42 can adopt various existing linear driving parts, such as cylinders, lead screw motors, etc.

[0070] As Figure 3 shown, optionally, the solder tape control mechanism in the embodiments of the present application further includes a limiting part 7 arranged on the base 1, and a first transfer assembly 8 and a second transfer assembly 9, wherein: the first transfer assembly 8 is fixedly connected to the first moving plate 2, and the second transfer assembly 9 is fixedly connected to the second moving plate 3. The limiting part 7 is configured to limit the moving distance between the first transfer assembly 8 and the second transfer assembly 9, so that each first chuck 5 and the paired second chuck 6 are semi-closed or closed.

[0071] By limiting the moving distance between the first transfer assembly 8 and the second transfer assembly 9 through the limiting part 7, the distance between the first chuck 5 and the paired second chuck 6 when they approach each other can be adjusted, thereby realizing the semi-closed or closed control of the first chuck 5 and the paired second chuck 6.

[0072] As Figures 2 to 3 、 Figures 7 to 8 shown, in some embodiments, when the first transfer assembly 8 and the second transfer assembly 9 approach each other, each first chuck 5 and the paired second chuck 6 are semi-closed or closed. The limiting part 7 includes a third driving part 71 and a limiting block 72. Among them, the third driving part 71 is installed on the base 1, and the limiting block 72 is slidably connected to the base 1 along the second horizontal direction and is connected to the driving end of the third driving part 71. The limiting block 72 is provided with a first limiting section 721 and a second limiting section 722 in the second horizontal direction. The width of the first limiting section 721 along the first horizontal direction is smaller than the width of the second limiting section 722 along the first horizontal direction. The third driving part 71 is used to drive the limiting block 72 to move along the second horizontal direction, so that the first limiting section 721 or the second limiting section 722 enters between the first transfer assembly 8 and the second transfer assembly 9.

[0073] When the third driving member 71 drives the limiting block 72 to move along the second horizontal direction to the first position, the first limiting section 721 of the limiting block 72 enters between the first adapter assembly 8 and the second adapter assembly 9.

[0074] As Figure 7 shown, when the driving part 4 drives the first moving plate 2 and the second moving plate 3 to approach each other along the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 also approach each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the two side walls of the first limiting section 721, and the first chuck 5 and the paired second chucks 6 are closed.

[0076] When the third driving member 71 drives the limiting block 72 to move along the second horizontal direction to the second position, the second limiting section 722 of the limiting block 72 enters between the first adapter assembly 8 and the second adapter assembly 9.

[0077] As Figure 7 shown, when the driving part 4 drives the first moving plate 2 and the second moving plate 3 to approach each other along the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 also approach each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the two side walls of the second limiting section 722, and the first chuck 5 and the paired second chucks 6 are semi-closed.

[0078] As Figure 8 shown, when the driving part 4 drives the first moving plate 2 and the second moving plate 3 to move away from each other along the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 approach each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the two side walls of the second limiting section 722, and the first chuck 5 and the paired second chucks 6 are semi-closed.

[0079] As Figures 9 to 10As shown, in some other embodiments, when the first adapter assembly 8 and the second adapter assembly 9 are away from each other, each first chuck 5 and the paired second chucks 6 are semi-closed or closed. The limiting portion 7 includes a third driving member and a limiting block 72. The third driving member is mounted on the base 1, and the limiting block 72 is slidably connected to the base 1 in the second horizontal direction and connected to the driving end of the third driving member. A limiting groove 723 facing the first adapter assembly 8 and the second adapter assembly 9 is provided on the limiting block 72. The limiting groove 723 is a V-shaped groove. Of course, the limiting groove 723 can also be a C-shaped groove. The third driving member is used to drive the limiting block 72 to move in the second horizontal direction so that the first adapter assembly 8 and the second adapter assembly 9 enter different positions in the limiting groove.

[0080] When the third driving member drives the limiting block 72 to move in the second horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 enter the narrower part of the limiting groove.

[0081] As Figure 9 shown, when the driving portion 4 drives the first moving plate 2 and the second moving plate 3 to approach each other in the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 are away from each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the opposite inner walls of the narrower part of the limiting groove 723, and the first chuck 5 and the paired second chucks 6 are semi-closed.

[0082] As Figure 10 shown, when the driving portion 4 drives the first moving plate 2 and the second moving plate 3 to move away from each other in the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 are away from each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the opposite inner walls of the narrower part of the limiting groove 723, and the first chuck 5 and the paired second chucks 6 are semi-closed.

[0083] When the third driving member drives the limiting block 72 to move in the second horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 enter the wider part of the limiting groove.

[0084] As Figure 9 shown, when the driving portion 4 drives the first moving plate 2 and the second moving plate 3 to approach each other in the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 are away from each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the opposite inner walls of the wider part of the limiting groove 723, and the first chuck 5 and the paired second chucks 6 are closed.

[0085] As Figure 10As shown, when the driving part 4 drives the first moving plate 2 and the second moving plate 3 to move away from each other along the first horizontal direction, the first adapter assembly 8 and the second adapter assembly 9 move away from each other. Finally, the first adapter assembly 8 and the second adapter assembly 9 respectively abut against the opposite inner walls of the wider part of the limiting groove 723, and the first chuck 5 and the paired second chucks 6 are closed.

[0086] As Figure 3 shown, optionally, the first adapter assembly 8 includes a first adapter block 81 and a first pressing block 82. Among them, the first adapter block 81 is fixedly connected to the first moving plate 2, and the first pressing block 82 is installed at the end of the first adapter block 81. The second adapter assembly 9 includes a second adapter block 91 and a second pressing block 92. Among them, the second adapter block 91 is fixedly connected to the second moving plate 3, and the second pressing block 92 is installed at the end of the second adapter block 91. The first pressing block 82 and the second pressing block 92 are respectively used to abut against the opposite sides of the limiting block 72, or the first pressing block 82 and the second pressing block 92 are respectively used to abut against the opposite sides of the limiting groove 723.

[0087] As Figures 1 to 3 shown, the first moving plate 2 is horizontally arranged, the first chuck 5 is arranged on the first moving plate 2 and extends along the second horizontal direction, and the first end of the first chuck 5 extends out of the first moving plate 2. The second moving plate 3 is located below or on the side of the first moving plate 2, the second chuck 6 is arranged vertically and extends upward out of the second moving plate 3, and the second chuck 6 cooperates with the first end of the first chuck 5 to clamp or hold the welding tape.

[0088] With such a setting, on the premise of ensuring that the second chuck 6 and the first chuck 5 can smoothly clamp or hold the welding tape, the first moving plate 2 can also support the welding tape to prevent the welding tape from sagging during traction or laying.

[0089] As Figure 2 shown, optionally, the welding tape control mechanism in the embodiment of the present application further includes n + 1 alignment blocks 101 arranged at intervals along the first horizontal direction on the first moving plate 2, and a first chuck 5 is correspondingly arranged between adjacent two alignment blocks 101, where:

[0090] The middle part of the i-th first chuck 5 is rotatably connected to the first moving plate 2, the second end of the i-th first chuck 5 is located between the i-th alignment block 101 and the (i + 1)-th alignment block 101, and a spring 102 is arranged between the second end of the i-th first chuck 5 and the (i + 1)-th alignment block 101. The spring 102 is used to elastically press the second end of the i-th first chuck 5 against the i-th alignment block 101, 1 ≤ i ≤ n.

[0091] For example, Figure 2As shown in the figure, the second end of the first chuck 5 is located between the first alignment block 101 and the second alignment block 101. A spring 102 between the second end of the first chuck 5 and the second alignment block 101 elastically presses the second end of the first chuck 5 against the first alignment block 101.

[0092] Since the middle part of the i-th first chuck 5 is rotatably connected to the first moving plate 2, and the second end of the i-th first chuck 5 is elastically pressed against the i-th alignment block 101. Therefore, when the i-th first chuck 5 closes with the paired i-th second chuck 6, the i-th first chuck 5 generates an adaptive deflection after contacting the welding tape, so as to ensure that the first end of the i-th first chuck 5 and the paired i-th second chuck 6 can clamp the welding tape.

[0093] That is, by setting the alignment block 101 and the spring 102, the first end of the first chuck 5 and the paired second chuck 6 can firmly clamp welding tapes of different thicknesses, thereby improving the compatibility of the application.

[0094] As Figure 2 and Figures 5 to 6 shown, optionally, the second chuck 6 is an L-shaped structure. The second chuck 6 includes a vertical part and a horizontal part. The vertical part is used to cooperate with the first end of the first chuck 5 to hold or clamp the welding tape, and the horizontal part is used to limit the welding tape from above. In this way, it can be ensured that the first end of the first chuck 5 and the paired second chuck 6 can stably hold or clamp the welding tape, preventing the welding tape from slipping out between the first end of the first chuck and the paired second chuck.

[0095] Of course, it is also possible to set the first end of the first chuck 5 as an L-shaped structure. The first end of the first chuck 5 includes a vertical part and a horizontal part. The vertical part is used to cooperate with the second chuck 6 to hold or clamp the welding tape, and the horizontal part is used to limit the welding tape from above.

[0096] To facilitate the forming and installation of the n second chucks 6, as Figures 5 to 6 shown, optionally, the n second chucks 6 are integrally formed at the upper end of the clamping plate 103, and the clamping plate 103 is fixed to the second moving plate 3 in the vertical direction.

[0097] The present application also provides a battery cell welding device. As Figure 11 shown, the battery cell welding device in the embodiment of the present application includes a welding tape traction mechanism 20, a battery cell loading mechanism 30, a welding bearing mechanism 40, a welding mechanism 50, and the welding tape control mechanism 10 described in any one of the above, wherein:

[0098] The welding bearing mechanism 40 is configured to reciprocate horizontally. A loading station and a welding station are sequentially arranged on the moving path of the welding bearing mechanism 40.

[0099] The solder tape traction mechanism 20 is used to traction the first solder tape group towards the welding carrier mechanism 40 located at the loading station, and to lay the first solder tape group on the welding carrier mechanism 40. The cell placing mechanism is used to stack cells on the first solder tape group. The solder tape traction mechanism 20 is also used to traction the second solder tape group towards the welding carrier mechanism 40, and to lay the second solder tape group on the cells.

[0100] The solder tape control mechanism 10 is located on the traction path of the solder tape group and close to the loading station. The solder tape control mechanism 10 is configured to clamp the first solder tape group or the second solder tape group when the solder tape traction mechanism 20 tractions the first solder tape group or the second solder tape group, so as to implement the guiding of the first solder tape group or the second solder tape group. The solder tape control mechanism 10 is also configured to clamp the tail end of the first solder tape group or the second solder tape group when the solder tape traction mechanism lays the first solder tape group or the second solder tape group, so as to straighten the first solder tape group or the second solder tape group.

[0101] The welding mechanism 50 is arranged at the welding station. The welding mechanism 50 is used to weld the first solder tape group and the second solder tape group located on the welding carrier mechanism 40 to the cells when the welding carrier mechanism 40 moves to the welding station.

[0102] Through the cooperation of the solder tape control mechanism 10, the solder tape traction mechanism 20, the cell placing mechanism 30, the welding carrier mechanism 40 and the welding mechanism 50, the cell welding device of the embodiment of the present application can automatically weld the solder tape group to the two surfaces of the cells, thereby realizing the automatic preparation of the replacement cells required for the repair of the battery string, and improving the preparation efficiency of the replacement cells. In particular, when the solder tape traction mechanism 20 tractions the first solder tape group or the second solder tape group, the solder tape control mechanism 10 implements clamping and guiding on the first solder tape group or the second solder tape group. When the solder tape traction mechanism 20 lays the first solder tape group or the second solder tape group, the solder tape control mechanism 10 cooperates with the solder tape traction mechanism 20 to implement clamping and straightening on the first solder tape group or the second solder tape group, and finally ensures that the first solder tape group or the second solder tape group is accurately laid at the target position.
