Description

Technical Field

[0001] This application relates to the technical field of photovoltaic cell production equipment, and more specifically, to a tooling transverse movement mechanism and a string welding machine. Background Technology

[0002] In battery assembly, the precise placement and curing of battery cells and solder ribbons on the conveyor line are crucial steps in fabricating high-efficiency battery strings. Taking the placement of solder ribbons on both the upper and lower surfaces of a battery cell as an example, the process typically includes: First, a traction mechanism precisely places the first set of solder ribbons at the placement station on the conveyor line. Then, a transport mechanism places the first battery cell on the rear half of the first set of solder ribbons. Next, the traction mechanism deploys the second set of solder ribbons at the placement station, with its front half covering the first battery cell. At this point, the transport mechanism uses tooling to press the front half of the second set of solder ribbons firmly onto the battery cell, while simultaneously placing the next battery cell on the rear half of the second set of solder ribbons. After the pressing and placement operation is completed, the traction mechanism releases the end of the second set of solder ribbons. Subsequently, the conveyor belt performs a step-by-step transport, sending the second battery cell to the placement station, and then the third set of solder ribbons is placed at the placement station again. The above steps are repeated until the battery string is completed.

[0003] In existing technologies, to ensure the precise positioning of the solder ribbon on the solar cell, starting from the second set of solder ribbons, the tooling must be pressed and released before the traction mechanism releases the ends of the solder ribbon. To avoid interference between the tooling and the traction mechanism during the pressing and releasing process, sufficient space must be reserved between the first half of the solder ribbon and the pre-placed position of the tooling to accommodate the clamping components of the traction mechanism. However, for more compact solar cell strings, the tooling gaps between adjacent cells are often insufficient to provide the required space, making the existing cell stringing process unsuitable for such compact designs and limiting the flexibility and applicability of the battery manufacturing process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a tooling transverse movement mechanism and a string welding machine, which adopts the following technical solution:

[0005] A tooling traversing mechanism includes a base, a traversing assembly, a lifting assembly, and a pushing unit, wherein:

[0006] The lateral movement assembly is mounted on the base;

[0007] The lifting assembly is mounted on the traversing component of the traversing assembly;

[0008] The pushing part is connected to the lifting drive end of the lifting assembly. The pushing part is used to push the tooling. The lateral moving assembly is configured to drive the pushing part to move laterally in the first direction after the pushing part is driven to a predetermined height by the lifting assembly.

[0009] This application designs a tooling lateral movement mechanism, which includes a base, a lateral movement component, a lifting component, and a pushing part. Specifically, the pushing part is connected to the lifting drive end of the lifting component, allowing the pushing part to first rise and fall to a predetermined position. The pushing part then moves laterally, pushing the tooling, which is pressed onto the welding strip and battery cells, to move laterally a predetermined distance along a first direction, where the first direction is the length direction of the welding strip. Therefore, during the battery string laying process, when the transport mechanism presses the tooling onto the welding strip and battery cells, the distance between the tooling and the front half of the welding strip can be greater than the target distance. Subsequently, before the welding strip is cured, the tooling lateral movement mechanism of this application is used to laterally move the tooling again, adjusting the distance between the tooling and the front half of the welding strip to the target distance.

[0010] This design not only increases the gap between tooling on adjacent cells during string laying, making it sufficient to accommodate clamping components in the traction mechanism, but also ensures that the cell stringing equipment can smoothly handle compact cell strings. Furthermore, since no extra length of welding ribbon is required, this improvement significantly reduces the amount of welding ribbon used, lowering the production cost of the cell strings. Through this innovative design, this application not only improves production efficiency but also enhances the applicability and flexibility of the equipment, solving the problem of traditional processes being unable to handle compact cell string layouts due to space constraints.

[0011] In some embodiments, the lateral movement assembly includes a lateral slide rail, a lateral movement component, and a lateral movement drive module, wherein:

[0012] The transverse slide rail is mounted on the base along the first direction;

[0013] The lateral movement component is slidably connected to the lateral slide rail and connected to the drive end of the lateral movement drive module;

[0014] The lateral movement drive module is configured to drive the lateral movement component to slide along the lateral slide rail.

[0015] The smooth and precise lateral movement of the pushing unit is achieved through the use of a lateral slide rail, a lateral moving component, and a lateral driving module. The lateral slide rail ensures the stability and straightness of the lateral moving component during movement, reducing tooling position errors that may occur due to movement deviations. This structure not only guarantees the stability of the overall process but also provides a foundation for subsequent lifting and pushing operations, ensuring smooth connection between each stage.

[0016] In some embodiments, the lateral drive module includes a first driving pulley, a first driven pulley, a first synchronous belt, a first drive motor, and a ball screw assembly, wherein:

[0017] The first driving pulley and the first driven pulley are spaced apart on the base along a second direction, which is perpendicular to the first direction;

[0018] The first synchronous belt is fitted onto the first driving pulley and the first driven pulley;

[0019] The power output end of the first drive motor is connected to the first drive pulley to drive the first drive pulley to rotate, and then drive the first driven pulley to rotate through the first synchronous belt;

[0020] The ball screw assembly includes a screw shaft and a nut. The screw shaft is rotatably mounted on a base in a first direction. The screw shaft is connected to a first driven pulley. The nut is connected to the screw shaft via ball threads and is connected to a lateral movement component. The nut is configured to drive the lateral movement component to move in the first direction when the screw shaft rotates.

[0021] This paper presents a first implementation of a traverse drive module, comprising a first driving pulley, a first driven pulley, a first synchronous belt, a first drive motor, and a ball screw assembly. The introduction of the ball screw assembly enables more precise position control of the traverse components during sliding, thereby ensuring the accuracy of the tooling position. The connection between the first driven pulley and the screw shaft makes the power transmission of the entire system more coordinated, reducing power loss and improving the operating efficiency of the traverse drive module. Furthermore, this design, through optimization of the mechanical structure, further improves the service life and reliability of the traverse drive module.

[0022] In some embodiments, the lateral drive module includes a second driving pulley, a second driven pulley, a second synchronous belt, and a second drive motor, wherein:

[0023] The second driving pulley and the second driven pulley are spaced apart on the base along the first direction;

[0024] The second synchronous belt is fitted onto the second driving pulley and the second driven pulley;

[0025] The lateral movement component is fixedly connected to one side of the second synchronous belt. The second drive motor is configured to drive the second drive pulley to rotate, thereby causing the second synchronous belt to rotate and thus causing the lateral movement component to move laterally.

[0026] This section presents a second implementation of the lateral movement drive module, which utilizes a second driving pulley, a second driven pulley, a second synchronous belt, and a second drive motor to drive the lateral movement component. The fixed connection between the lateral movement component and the second synchronous belt ensures smoothness and straightness during lateral movement. The cooperation between the driving and driven pulleys makes the entire drive process more coordinated, avoiding potential lag during power transmission. Compared to the first implementation of the lateral movement drive module described above, this design eliminates the need for a ball screw assembly, resulting in a simpler structure while still achieving precise lateral movement control.

[0027] In some embodiments, the traversing component includes a traversing platform, a connecting plate, and a plurality of first bolts, wherein:

[0028] The transverse platform is slidably connected to the transverse slide rail, and several arc-shaped waist holes are opened on the transverse platform;

[0029] The connecting plate is installed below the transverse platform, the lifting assembly is installed on the connecting plate, and the top of the connecting plate is provided with several first threaded holes that correspond one-to-one with each of the arc-shaped waist holes.

[0030] The stud of the first bolt passes through the arc-shaped waist hole and is threaded into the first threaded hole to fix the connecting plate on the transverse platform.

[0031] The sliding connection between the traverse platform and the transverse slide rail ensures the stability and straightness of the traverse component during movement. The connecting plate allows the lifting assembly to be fixed below the traverse platform, providing stable support for the vertical movement of the pushing unit. This structural design not only improves the overall stability of the equipment but also provides a reliable mechanical foundation for subsequent operations. Furthermore, the combination of the traverse platform and the connecting plate makes maintenance and replacement of the traverse component more convenient, reducing equipment maintenance costs. The traverse platform is connected to the connecting plate via a first bolt passing through an arc-shaped waist hole and a first threaded hole. When the first bolt is loosened, it can rotate within the arc-shaped waist hole, thereby adjusting the position of the connecting plate relative to the traverse platform. This adjustment of the relative position of the connecting plate and the traverse platform ensures that the pushing unit accurately adjusts the position of the tooling.

[0032] In some embodiments, the lifting assembly includes a vertical slide rail and a lifting drive module, wherein:

[0033] The vertical slide rail is installed vertically on the horizontal moving component;

[0034] The pusher is slidably connected to the vertical slide rail and connected to the drive end of the lifting drive module;

[0035] The lifting drive module is configured to drive the push unit to slide up and down along the vertical slide rail.

[0036] The connection between the lifting drive module and the push unit enables the push unit to push the tooling at a predetermined height.

[0037] In some embodiments, the pushing part includes a push plate connected to the lifting drive end of the lifting assembly. The push plate is provided with a pushing surface for pushing the tooling. The pushing surface of the push plate extends along a second direction, which is perpendicular to the first direction.

[0038] The pushing surface extends along the second direction, ensuring uniform force distribution on the tooling during the pushing process and improving the positional accuracy of the tooling.

[0039] In some embodiments, the pushing part includes a push plate, a first pusher, and a second pusher, wherein:

[0040] The push plate is connected to the lifting drive end of the lifting assembly;

[0041] The first pusher and the second pusher are respectively located at both ends of the push plate;

[0042] Both the first and second pushers are provided with a pushing surface for pushing the tooling, and the pushing surface is located below the push plate.

[0043] The first and second pushers are used to push against both ends of the tooling, making the tooling more balanced during movement.

[0044] A string welding machine includes the aforementioned tooling traversing mechanism.

[0045] In some embodiments, the string welding machine further includes a conveyor line, a traction mechanism, a handling mechanism, and a curing mechanism, wherein:

[0046] The conveyor line is used to transport battery cells, welding strips and tooling. The conveyor line is sequentially equipped with a laying station, a transverse moving station and a curing station along the conveying path in the first direction.

[0047] The traction mechanism is configured to clamp the end of the welding strip and lay the first half of the welding strip onto the battery cell located at the laying station, while the second half of the welding strip is laid onto the conveyor line.

[0048] The conveying mechanism is configured to press the tooling onto the first position of the front half of the welding strip, and the traction mechanism is configured to release the end of the welding strip;

[0049] The handling mechanism is also configured to lay the next cell onto the latter half of the welding strip;

[0050] The conveyor line is configured to move forward in a stepping manner, so that while the cell at the laying station moves forward to the traversing station, the next cell moves to the laying station.

[0051] The tooling traverse mechanism is located above the traverse station and is configured to push the tooling on the cell at the traverse station to traverse along the conveying direction of the conveyor line, so that the tooling is traversely moved to a second position on the first half of the welding strip.

[0052] The distance between the tooling in the first position and the end of the first half of the welding strip is greater than the distance between the tooling in the second position and the end of the first half of the welding strip. The gap between the tooling in the first position and the previous tooling allows the clamping component of the traction mechanism to be inserted to clamp the end of the welding strip.

[0053] The curing mechanism is located above the curing station and is configured to fix the solder ribbon located at the curing station to the corresponding solar cell.

[0054] The stringing machine provided in this application achieves full automation of the battery cell stringing process by combining a tooling traversing mechanism with a conveyor line, traction mechanism, handling mechanism, and curing mechanism. During battery string laying, when the handling mechanism presses the tooling onto the welding strip and battery cells, the distance between the tooling and the first half of the welding strip can be greater than the target distance. When the tooling is transported to the curing station, the tooling traversing mechanism moves the tooling laterally, thereby adjusting the distance between the tooling and the first half of the welding strip to the target distance, ensuring that the welding strip is cured on the corresponding battery cell as required. Using the stringing machine provided in this application, the gap between the tooling on adjacent battery cells increases during battery string laying. This gap is sufficient to accommodate the clamping components in the traction mechanism, ultimately ensuring that the battery cell stringing equipment can successfully string compact battery cells. Furthermore, during battery string laying, no extra length of welding strip is required, thus saving welding strip usage and reducing the production cost of the battery cells.

[0055] In some embodiments, the base of the tooling traverse mechanism includes a support and a mounting plate mounted on the support, the mounting plate being used to support the traverse assembly;

[0056] The mounting plate has several stepped holes, and the top of the support has several second threaded holes that correspond one-to-one with the stepped holes. The mounting plate is fixed to the support by a second bolt that passes through the stepped holes and is threaded to the second threaded holes. The nut of the second bolt is located inside the stepped hole, and the radial dimension of the nut of the second bolt is smaller than the radial dimension of the stepped hole.

[0057] The tooling traverse mechanism also includes a calibration plate, the first end of which is detachably mounted on the end of the traction mechanism near the mounting plate, the calibration plate being perpendicular to the traction mechanism, and the second end of which is detachably mounted on the traverse assembly.

[0058] This application provides a mounting plate with several stepped holes, and a second threaded hole corresponding to each stepped hole is provided at the top of the support. A second bolt passes through the stepped hole and is threaded into the second threaded hole to fix the mounting plate to the support. The nut of the second bolt is located in the stepped hole, and the radial dimension of the stepped hole is larger than the radial dimension of the nut of the second bolt. When the second bolt is not tightened, the mounting plate is configured to rotate horizontally on the support. The first end of the calibration plate is first installed on the traction mechanism. At this time, the position of the mounting plate relative to the support is adjusted so that the second end of the calibration plate can be accurately installed on the transverse component to adjust the straightness of the transverse component relative to the traction mechanism, so as to ensure that the push plate of the push part is parallel to the tooling and that the tooling is not skewed when the push plate of the push part pushes the tooling.

[0059] Compared with the prior art, the beneficial effects of the technical solution of this application are:

[0060] This application provides a tooling traversing mechanism and a string welding machine. During the battery string laying process, the design of the tooling traversing mechanism increases the gap between tooling on adjacent battery cells, making the gap sufficient to accommodate the clamping components of the traction mechanism. This overcomes the limitations of traditional processes when dealing with compact battery strings. Furthermore, during battery string laying, no extra length of welding strip is required, saving material consumption of the welding strip and reducing the production cost of the battery strings.

[0077] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0078] like Figure 1 As shown, the tooling transverse movement mechanism 10 in this embodiment includes a base 1, a transverse movement component 2, a lifting component 3, and a pushing part 4, wherein:

[0079] The transverse component 2 is mounted on the base 1;

[0080] The lifting assembly 3 is mounted on the transverse component 22 of the transverse assembly 2;

[0081] The pushing part 4 is connected to the lifting drive end of the lifting assembly 3. The pushing part 4 is used to push the tooling 50. The lateral moving assembly 2 is configured to drive the pushing part 4 to move laterally in the first direction after the pushing part 4 is driven to rise and fall to a predetermined height by the lifting assembly 3.

[0082] This application designs a tooling lateral movement mechanism 10, which includes a base 1, a lateral movement component 2, a lifting component 3, and a pushing part 4. Specifically, the pushing part 4 is connected to the lifting drive end of the lifting component 3, allowing the pushing part 4 to first rise and fall to a predetermined position. The pushing part 4 then moves laterally, pushing the tooling 50, which is pressed onto the welding strip and battery cells, to move laterally a predetermined distance along a first direction, where the first direction is the length direction of the welding strip. Therefore, during the battery string laying process, when the transport mechanism presses the tooling 50 onto the welding strip and battery cells, the distance between the tooling 50 and the end of the first half of the welding strip can be greater than the target distance. Subsequently, before the welding strip is cured, the tooling lateral movement mechanism 10 of this application is used to laterally move the tooling 50, adjusting the distance between the tooling 50 and the end of the first half of the welding strip to the target distance.

[0083] This design not only increases the gap between the tooling 50 on adjacent cells during the battery string laying process, thus accommodating the clamping components in the traction mechanism 30, but also ensures that the cell stringing equipment can smoothly handle compact battery strings. Furthermore, since no extra length allowance is needed for the welding ribbon, this improvement significantly saves on welding ribbon usage and reduces the production cost of the battery strings. Through this innovative design, this application not only improves production efficiency but also enhances the applicability and flexibility of the equipment, solving the problem of traditional processes being unable to handle compact battery string layouts due to space constraints.

[0084] Continue to refer to Figure 1As shown, optionally, the lateral movement assembly 2 includes a lateral slide rail 21, a lateral movement component 22, and a lateral movement drive module 23, wherein:

[0085] The transverse slide rail 21 is mounted on the base 1 along the first direction;

[0086] The lateral movement component 22 is slidably connected to the lateral slide rail 21 and connected to the drive end of the lateral movement drive module 23;

[0087] The lateral movement drive module 23 is configured to drive the lateral movement component 22 to slide along the lateral slide rail 21.

[0088] The smooth and precise lateral movement of the pushing unit 4 is achieved through the transverse slide rail 21, the lateral moving component 22, and the lateral driving module 23. The transverse slide rail 21 ensures the stability and straightness of the lateral moving component 22 during movement, reducing the positional error of the tooling 50 that may be caused by movement deviation. This structure not only ensures the stability of the overall process but also provides a foundation for subsequent lifting and pushing operations, ensuring smooth connection between each link.

[0089] Continue to refer to Figure 1 As shown, optionally, the lateral drive module 23 includes a first driving pulley 231, a first driven pulley 232, a first synchronous belt 233, a first drive motor 234, and a ball screw assembly 235, wherein:

[0090] The first driving pulley 231 and the first driven pulley 232 are spaced apart on the base 1 along a second direction, which is perpendicular to the first direction.

[0091] The first synchronous belt 233 is fitted onto the first driving pulley 231 and the first driven pulley 232;

[0092] The power output end of the first drive motor 234 is connected to the first drive pulley 231 to drive the first drive pulley 231 to rotate, and then drive the first driven pulley 232 to rotate through the first synchronous belt 233.

[0093] The ball screw assembly 235 includes a screw shaft and a nut. The screw shaft is rotatably mounted on the base 1 in a first direction. The screw shaft is connected to the first driven pulley 232. The nut is connected to the screw shaft by ball threads. The nut is connected to the transverse member 22. The nut is configured to drive the transverse member 22 to move in the first direction when the screw shaft rotates.

[0094] This document presents a first implementation of the transverse drive module 23, which includes a first driving pulley 231, a first driven pulley 232, a first synchronous belt 233, a first drive motor 234, and a ball screw assembly 235. The introduction of the ball screw assembly 235 enables more precise position control of the transverse component 22 during sliding, thereby ensuring the accuracy of the tooling 50's position. The connection between the first driven pulley 232 and the screw shaft makes the power transmission of the entire system more coordinated, reducing power loss and improving the operating efficiency of the transverse drive module 23. Furthermore, this design, through optimization of the mechanical structure, further improves the service life and reliability of the transverse drive module 23.

[0095] Optionally, the lateral drive module 23 includes a second driving pulley, a second driven pulley, a second synchronous belt, and a second drive motor, wherein:

[0096] The second driving pulley and the second driven pulley are spaced apart on the base 1 along the first direction;

[0097] The second synchronous belt is fitted onto the second driving pulley and the second driven pulley;

[0098] The lateral movement component 22 is fixedly connected to one side of the second synchronous belt. The second drive motor is configured to drive the second drive pulley to rotate, thereby driving the second synchronous belt to rotate and thus driving the lateral movement component 22 to move laterally.

[0099] A second implementation of the lateral movement drive module 23, not shown in the accompanying drawings, is provided here. This implementation uses a second driving pulley, a second driven pulley, a second synchronous belt, and a second drive motor to drive the lateral movement component 22. The fixed connection between the lateral movement component 22 and the second synchronous belt ensures smoothness and straightness during lateral movement. The cooperation between the driving and driven pulleys makes the entire drive process more coordinated, avoiding potential lag in power transmission. Compared to the first implementation of the lateral movement drive module 23 described above, this design eliminates the need for the ball screw assembly 235, resulting in a simpler structure while still achieving precise lateral movement control. Of course, those skilled in the art can replace the lateral movement drive module with existing linear drive modules of other structures, provided the replacement lateral movement drive module can drive the lateral movement component 22 to move laterally.

[0100] refer to Figure 1 and Figure 4 As shown, optionally, the lateral moving component 22 includes a lateral moving platform 221, a connecting plate 222, and a plurality of first bolts, wherein:

[0101] The transverse platform 221 is slidably connected to the transverse slide rail 21, and several arc-shaped waist holes 2211 are provided on the transverse platform 221;

[0102] The connecting plate 222 is installed below the transverse platform 221, and the lifting assembly 3 is installed on the connecting plate 222. The top of the connecting plate 222 is provided with a number of first threaded holes that correspond one-to-one with each of the arc-shaped waist holes 2211.

[0103] The stud of the first bolt passes through the arc-shaped waist hole 2211 and is threadedly connected to the first threaded hole to fix the connecting plate 222 on the transverse platform 221.

[0104] The sliding connection between the transverse platform 221 and the transverse slide rail 21 ensures the stability and straightness of the transverse component 22 during movement. The connecting plate 222 allows the lifting assembly 3 to be fixed below the transverse platform 221, providing stable support for the vertical movement of the pushing unit 4. This structural design not only improves the overall stability of the equipment but also provides a reliable mechanical foundation for subsequent operations. Furthermore, the combination of the transverse platform 221 and the connecting plate 222 makes maintenance and replacement of the transverse component 22 more convenient, reducing equipment maintenance costs. The transverse platform 221 is connected to the connecting plate 222 via a first bolt passing through the arc-shaped waist hole 2211 and the first threaded hole. This allows the first bolt to rotate within the arc-shaped waist hole 2211 when the connecting plate 222 is loosened, adjusting the position of the connecting plate 222 relative to the transverse platform 221, thereby adjusting the perpendicularity of the pushing unit 4 to the tooling to ensure that the pushing unit 4 accurately adjusts the position of the tooling.

[0105] Continue to refer to Figure 1 As shown, optionally, the lifting assembly 3 includes a vertical slide rail 31 and a lifting drive module 32, wherein:

[0106] The vertical slide rail 31 is mounted vertically on the horizontal moving component 22;

[0107] The pusher 4 is slidably connected to the vertical slide rail 31 and connected to the drive end of the lifting drive module 32;

[0108] The lifting drive module 32 is configured to drive the push unit 4 to slide up and down along the vertical slide rail 31.

[0109] The drive end of the lifting drive module 32 is connected to the push unit 4, which drives the push unit 4 to lift and lower to a predetermined height, so that the push unit 4 can push the tooling 50 at the predetermined height.

[0110] Optionally, the pushing part 4 includes a push plate 41, which is connected to the lifting drive end of the lifting assembly 3. The push plate 41 is provided with a pushing surface for pushing the tooling 50. The pushing surface of the push plate 41 extends along a second direction, which is perpendicular to the first direction.

[0111] The pushing surface extends along the second direction, ensuring that the tooling 50 is subjected to uniform force during the pushing process and improving the positional accuracy of the tooling 50.

[0112] Continue to refer to Figure 1 As shown, optionally, the pushing part 4 includes a push plate 41, a first pusher 42, and a second pusher 43, wherein:

[0113] The push plate 41 is connected to the lifting drive end of the lifting assembly 3;

[0114] The first pusher 42 and the second pusher 43 are respectively disposed at both ends of the pusher plate 41;

[0115] Both the first pusher 42 and the second pusher 43 are provided with a pushing surface for pushing the tooling 50, and the pushing surface is located below the pusher plate 41.

[0116] The first pusher 42 and the second pusher 43 are used to push against both ends of the tooling 50, making the tooling 50 more balanced during movement. The pushing surfaces of the first pusher 42 and the second pusher 43 can be set as flat or slightly curved surfaces to adapt to tooling 50 of different shapes. In addition, first pushers 42 and second pushers 43 of different shapes can also be selected to adapt to tooling 50 and battery cells of different specifications.

[0117] To enable those skilled in the art to more clearly understand the working principle of the tooling transverse movement mechanism 10 in the embodiments of this application, the following will be combined with Figure 2-5 The working process of the tooling transverse movement mechanism 10 is described by way of example, wherein, Figure 3 The battery assembly 60 includes solder strips and battery cells.

[0118] During the battery string laying process, when the transport mechanism presses the fixture 50 onto the welding strip and battery cells, the distance between the fixture 50 and the front half of the welding strip is greater than the target distance. This ensures that the distance between the currently placed fixture 50 and the previous fixture 50 is sufficient to accommodate the clamping components of the traction mechanism 30, preventing the fixture 50 from colliding with the traction mechanism 30. Subsequently, before the welding strip is cured, the fixture 50 is moved laterally by the fixture lateral movement mechanism 10 to adjust the distance between the fixture 50 and the front half of the welding strip to the target distance. This ensures that the fixture 50 can press the front half of the welding strip firmly onto the corresponding solder pads on the upper surface of the battery cells, ultimately guaranteeing the stringing quality of the battery string.

[0119] Based on the same technical concept, this application also provides a string welding machine, which includes the tooling transverse movement mechanism 10 in any of the above embodiments.

[0120] like Figure 5 As shown, optionally, the string welding machine also includes a conveyor line 20, a traction mechanism 30, a handling mechanism, and a curing mechanism 40, wherein:

[0121] The conveyor line 20 is used to transport battery cells, welding strips and tooling 50. The conveyor line 20 is provided with a laying station, a transverse moving station and a curing station in sequence along the conveying path in the first direction.

[0122] The traction mechanism 30 is configured to clamp the end of the welding strip and lay the first half of the welding strip onto the battery cell located at the laying station, while the second half of the welding strip is laid onto the conveyor line 20.

[0123] The conveying mechanism is configured to press the tooling 50 onto the first position of the front half of the welding strip, and the traction mechanism 30 is configured to release the end of the welding strip;

[0124] The handling mechanism is also configured to lay the next cell onto the latter half of the welding strip;

[0125] The conveyor line 20 is configured to move forward in a stepping manner, such that while the cell at the laying station moves forward to the traversing station, the next cell moves to the laying station.

[0126] The tooling lateral movement mechanism 10 is located above the lateral movement station. The tooling lateral movement mechanism 10 is configured to push the tooling 50 on the battery cell located at the lateral movement station to move laterally along the conveying direction of the conveyor line 20, so that the tooling 50 moves laterally to a second position on the first half of the welding strip.

[0127] The distance between the tooling 50 in the first position and the end of the first half of the welding strip is greater than the distance between the tooling 50 in the second position and the end of the first half of the welding strip. The gap between the tooling 50 in the first position and the previous tooling 50 allows the clamping component of the traction mechanism 30 to be inserted to clamp the end of the welding strip.

[0128] The curing mechanism 40 is located above the curing station and is configured to fix the solder ribbon located at the curing station to the corresponding solar cell.

[0129] The traction mechanism 30 can be any existing mechanism capable of laying welding strips. For example, the traction mechanism 30 includes a first moving component and a clamping component disposed on the driving end of the first moving component. The first moving component is used to drive the clamping component to move so that the clamping component clamps the end of the welding strip to be laid and then lays the welding strip onto the battery cell and conveyor line 20 at the laying station.

[0130] The handling mechanism can adopt various mechanisms capable of handling battery cells and tooling 50. For example, the handling mechanism includes a second moving component and a suction cup component and a magnetic suction component arranged side by side on the driving end of the second moving component. The second moving component is used to drive the suction cup component and the magnetic suction component to move synchronously, so as to drive the suction cup component to pick up the battery cell and transport the battery cell to the conveyor line 20, and drive the magnetic suction component to pick up the tooling 50 and press the tooling 50 onto the corresponding battery cell.

[0131] The curing mechanism 40 can be an infrared light box, an LED light box, or a laser welding mechanism, which can cure the solder strip onto the battery cell.

[0132] The stringing machine provided in this application achieves full automation of the battery cell stringing process by combining the tooling traversing mechanism 10 with the conveyor line 20, traction mechanism 30, handling mechanism, and curing mechanism 40. During the battery string laying process, when the handling mechanism presses the tooling 50 onto the welding strip and battery cell, the distance between the tooling 50 and the front half of the welding strip can be greater than the target distance. When the tooling 50 is conveyed to the curing station, the tooling traversing mechanism 10 traverses the tooling 50, thereby adjusting the distance between the tooling 50 and the front half of the welding strip to the target distance, ensuring that the welding strip is cured on the corresponding battery cell as required. Using the stringing machine provided in this application, during the battery string laying process, the gap between the tooling 50 on two adjacent battery cells increases, and this gap is sufficient to accommodate the clamping components in the traction mechanism 30, ultimately ensuring that the battery cell stringing equipment can successfully string compact battery cells. In addition, during the battery string laying process, there is no need to leave extra length of welding ribbon, which saves welding ribbon usage and reduces the production cost of battery strings.

[0133] like Figure 6 As shown, optionally, the base 1 in the tooling transverse movement mechanism 10 includes a support 11 and a mounting plate 12 mounted on the support 11, the mounting plate 12 being used to support the transverse movement assembly 2;

[0134] The mounting plate 12 has several stepped holes 121, and the top of the support 11 has several second threaded holes that correspond one-to-one with the stepped holes 121. The mounting plate 12 is fixed to the support 11 by a second bolt that passes through the stepped holes 121 and is threaded to the second threaded holes. The nut of the second bolt is located inside the stepped hole 121, and the radial dimension of the nut of the second bolt is smaller than the radial dimension of the stepped hole 121.

[0135] The tooling transverse movement mechanism 10 also includes a calibration plate 70. The first end of the calibration plate 70 is detachably mounted on the end of the traction mechanism near the mounting plate 12. The calibration plate 70 is perpendicular to the traction mechanism. The second end of the calibration plate 70 is detachably mounted on the transverse movement platform 221 of the transverse movement assembly 2.

[0136] The second bolt includes a nut and a shank, with the diameter of the nut being larger than that of the shank. The stepped hole 121 is a hole with a stepped structure, which includes segments of different diameters to form a stepped shape. The entrance diameter of the stepped hole 121 is larger, and the internal diameter is smaller. That is, the stepped hole 121 includes a larger diameter segment and a smaller diameter segment from top to bottom.

[0137] The larger diameter section of the stepped hole 121 is designed to accommodate the nut. The diameter of the nut is smaller than the diameter of the larger diameter section of the stepped hole 121. Furthermore, the diameter of the nut is larger than the diameter of the smaller diameter section. This ensures that the nut will not sink into the smaller diameter section when the second bolt is tightened, allowing the second bolt to secure the mounting plate 12 to the support 11.

[0138] The smaller diameter section of the stepped hole 121 is to provide space for the screw to pass through, and the diameter of the screw is smaller than that of the smaller diameter section. When the second bolt is not tightened, the lower end of the screw is still fixedly connected in the second threaded hole, so the screw does not move. However, because the second bolt is not tightened, there is a gap between the bottom surface of the nut and the bottom surface of the larger diameter section, which allows the mounting plate 12 to rotate horizontally on the support 11. The first end of the calibration plate 70 is first installed on the traction mechanism. At this time, the position of the mounting plate 12 relative to the support 11 is adjusted so that the second end of the calibration plate 70 can be accurately installed on the transverse platform 221 of the transverse component 2 to adjust the straightness of the transverse component 2 relative to the traction mechanism, so as to ensure that the conveying direction of the tooling is parallel to the conveying direction of the transverse component 2. When the push plate 41 of the push part 4 pushes the tooling 50, the tooling 50 will not be deflected.
