[0082] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0083] The welding ribbon positioning and handling device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0084] Reference Figures 1 to 22 As shown, the welding ribbon positioning and conveying equipment provided according to an embodiment of the present invention includes a welding conveyor line 10 , a welding ribbon guiding mechanism 20 , two welding ribbon conveying mechanisms 30 and a welding ribbon clamping mechanism 40 .

[0085] Specifically, the welding conveyor line 10 is used to load and convey stacked cells and solder ribbons. The stacked cells and solder ribbons can be transported to the welding station at a constant speed using the welding conveyor line 10. When they arrive at the welding station, the cells are welded using the welding equipment at the welding station.

[0086] The ribbon guide mechanism 20 is located outside the loading end of the welding conveyor line 10 and is used to arrange multiple ribbons side by side and guide them in the conveying direction. Since multiple ribbons are typically required for cell welding, and these ribbons need to correspond to corresponding positions on the cell, in order to ensure the correct and orderly conveyance of these ribbons, the ribbon guide mechanism 20 is used in this application to align multiple dispersed ribbons side by side, ensuring that they remain in a parallel and orderly arrangement and fixed in position before entering the welding conveyor line 10.

[0087] The two solder ribbon transport mechanisms 30 are located adjacent to the loading end of the welding conveyor line 10 and are used to alternately transport the solder ribbons to the loading end of the welding conveyor line 10. In other words, the solder ribbon transport mechanisms 30 transport the orderly arranged solder ribbons to the loading end of the welding conveyor line 10. Furthermore, the use of two solder ribbon transport mechanisms 30 for alternating transport enables continuous transport, compared to the reciprocating transport method of a single solder ribbon transport mechanism 30, saving transport time and improving transport efficiency.

[0088] The ribbon clamping mechanism 40 is located between the loading end of the welding conveyor line 10 and the ribbon guide mechanism 20. It is used to clamp the individual ribbons extending from the ribbon guide mechanism 20 and, in the clamped state, allows the ribbon transport mechanism 30 to transfer the ribbons. In other words, the ribbon clamping mechanism 40 is used to clamp and secure the parallel ribbons extending from the ribbon guide mechanism 20, ensuring that these ribbons maintain accurate position and alignment when being transported to the conveyor line by the ribbon transport mechanism 30.

[0089] The working process of the welding ribbon positioning and handling equipment is as follows:

[0090] A plurality of soldering ribbons are fed into the soldering ribbon guiding mechanism 20 . Under the action of the soldering ribbon guiding mechanism 20 , the soldering ribbons are arranged side by side in an orderly manner, and the position of each soldering ribbon is determined.

[0091] The welding ribbon transport mechanism 30 clamps each welding ribbon and transfers it to the loading end of the welding conveyor belt 103 , so that each welding ribbon is transferred to the loading end of the welding conveyor line 10 and moves along the conveying direction of the welding conveyor line 10 .

[0092] On the output side of the ribbon guide mechanism 20, the ribbon clamping mechanism 40 clamps each ribbon, further precisely fixing its position and ensuring that the ribbons maintain their correct stacking position with the solar cells after being delivered to the welding conveyor line 10. During the transport process, the two ribbon transport mechanisms 30 alternately clamp, release, and transfer the ribbons, completing the alternating transfer of the ribbons.

[0093] According to the welding tape positioning and conveying equipment provided by the embodiment of the present invention, the welding tape conveying mechanism 30 is used to clamp the welding tape and convey it to the welding conveyor line 10. During this process, the welding tape guiding mechanism 20 is used to arrange multiple welding tapes side by side and guide them in order, and the welding tape clamping mechanism 40 can clamp and position each welding tape on the output side of the welding tape guiding mechanism 20, so that each welding tape is kept in an accurate position. In this way, the various welding tapes can be arranged in an orderly manner and stably transferred to the welding conveyor line 10, and then the stacked battery cells and welding tapes are conveyed to the welding station by the welding conveyor line 10. In this way, the welding efficiency can be significantly improved and the requirements of high-speed string welding can be met.

[0094] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the welding ribbon conveyor line 10 includes a conveyor frame 101, a telescopic frame 102, a conveyor belt 103, a telescopic drive device 104 and a rotation drive device 105, and the telescopic frame 102 is arranged on the conveyor frame 101 and can slide along the conveying direction.

[0095] The conveyor belt 103 is wound between the conveyor frame 101 and the telescopic frame 102, and the effective length of the conveyor belt 103 is changed when the telescopic frame 102 slides, so that the loading end of the conveyor belt 103 has a larger loading range. Secondary loading can be performed during the welding waiting process, avoiding loading waiting and improving overall efficiency.

[0096] The telescopic drive device 104 is provided on the conveying frame 101 and connected to the telescopic frame 102 to drive the telescopic frame 102 to slide along the conveying direction. The telescopic drive device 104 generally adopts a screw motor or a cylinder mechanism to drive the telescopic frame 102 to slide back and forth along the conveying direction.

[0097] The rotary drive device 105 is used to drive the conveyor belt 103 to move, so as to transport the stacked battery cells and welding ribbons to the welding station through the conveyor belt 103. The rotary drive device 105 can adopt a driving device such as a stepping motor.

[0098] During the welding process, when the welding conveyor line 10 delivers a set of battery cells and welding ribbons to the welding station, it needs to wait until the welding equipment at the welding station completes welding before continuing to convey. To improve overall efficiency, in this embodiment, during the welding process at the welding station, the telescopic drive mechanism can drive the telescopic frame 102 to slide toward the loading end of the conveyor frame 101, thereby extending the conveyor belt 103 and increasing the loading area. At this time, another set of battery cells and welding ribbons can be loaded, and the time required for the two loadings is equivalent to the welding time at the welding station.

[0099] Through this scalable design, the loading end section of the welding ribbon conveyor line can be expanded according to demand, providing convenience for secondary loading and realizing secondary loading during the welding waiting time. In this way, the production efficiency of the entire welding production line is improved to meet the requirements of high speed and high production capacity.

[0100] Reference Figure 3 and Figure 4 As shown, in one embodiment of the present invention, a driving roller 1011 is provided at one end of the conveying frame 101 , and a first driven roller 1012 is provided at the other end of the conveying frame 101 .

[0101] A second driven roller 1013 is also provided on the conveying frame 101, and the second driven roller 1013 is separated from the first driven roller 1012 by a predetermined distance in the conveying direction. A third driven roller 1021 is provided on the telescopic frame 102, and the third driven roller 1021 is located between the first driven roller 1012 and the second driven roller 1013. One end of the conveyor belt 103 is wound around the active roller 1011, and the other end of the conveyor belt 103 is wound around the first driven roller 1012, the second driven roller 1013 and the third driven roller 1021 in sequence.

[0102] With the above structure, a part of the conveyor belt 103 located on the telescopic frame 102 and the other part located on the conveyor frame 101 form a double-layer structure similar to an upper and lower layer. As the telescopic frame 102 slides, the length relationship between the two parts of the conveyor belt 103 can be changed. For example, when secondary loading is required, the telescopic frame 102 can be slid toward the end of the conveyor frame 101. In this way, a flexible and telescopic adjustable structure can be formed, ensuring the reliability and stability of the adjustment.

[0103] Reference Figures 6 to 18 As shown, in some embodiments of the present invention, the welding ribbon guide mechanism 20 includes a guide plate 201, a guide sealing plate 207 and a first driving member 208. The top surface of the guide plate 201 is provided with a plurality of guide grooves H20, and the plurality of guide grooves H20 are arranged at intervals along the first direction. Each of the guide grooves H20 extends along the second direction and passes through the guide plate 201. The first direction is perpendicular to the second direction, and the second direction is parallel to the conveying direction. In a specific application, a plurality of welding ribbons can be respectively loaded into each guide groove H20, and the welding ribbons can move along the second direction in the guide groove H20, so that the plurality of guide grooves H20 can guide a plurality of welding ribbons at the same time. For example, the first direction is the left-right direction, and the second direction is the front-back direction.

[0104] The guide sealing plate 207 includes a plate body 2071 and a folding strip 2072. The plate body 2071 is disposed at the bottom of the guide plate 201 and is slidable along the first direction. The folding strip 2072 is formed at one end of the plate body 2071 in the second direction and is located outside the guide plate 201 and extends along the first direction. In this way, the guide sealing plate 207 can slide relative to the guide plate 201 in the first direction.

[0105] The first driving member 208 is used to drive the guide sealing plate 207 to slide along the first direction between an open position and a closed position relative to the guide plate 201. The first driving member 208 can be a cylinder, a linear module, etc.

[0106] There are multiple openings H22 on the folding strip 2072, and the multiple openings H22 correspond one-to-one to the multiple guide grooves H20. The upper end of each opening H22 has a guard portion 2072a and a wire passing opening H221. The guard portion 2072a and the wire passing opening H221 are arranged side by side in the first direction. The wire passing opening H221 is connected to the opening H22, so that the welding strip can enter the opening H22 from the wire passing opening H221.

[0107] When the guide sealing plate 207 is in the open position, the wire-passing opening H221 is opposite to the guide groove H20, so that the welding ribbon can enter the guide groove H20 from the wire-passing opening H221. At this time, the sidewall portion 2072a is in a misaligned state with the guide groove H20, and the welding ribbon extends in the guide groove H20 and passes through the opening H22. When the guide sealing plate 207 is in the closed position, the sidewall portion 2072a is opposite to the guide groove H20 to close the open side of the guide groove H20, so that the welding ribbon is confined in the guide groove H20 and cannot escape. At this time, the wire-passing opening H221 is in a misaligned state with the guide groove H20, and the welding ribbon extends in the guide groove H20 and passes through the opening H22. Moreover, since the sidewall portion 2072a closes the open side of the guide groove H20, the welding ribbon cannot escape from the guide groove H20.

[0108] It should be noted that when the guide sealing plate 207 is in the open position, since the wire passing opening H221 is opposite to the guide groove H20, the guide groove H20 is in a fully open state, and the welding strip can enter the guide groove H20 very conveniently. There is no other resistance in this process, which ensures the reliability of the welding strip entering the guide groove H20.

[0109] The welding ribbon guide mechanism 20 of this embodiment uses the guide sealing plate 207 to control the opening and closing of the guide groove H20, thereby achieving flexible introduction and reliable fixation of the welding ribbon. When the guide sealing plate 207 is in the open position, the welding ribbon can easily enter the guide groove H20 through the wire opening H221 on the folding strip 2072, facilitating the rapid loading of the welding ribbon; when the guide sealing plate 207 is moved to the closed position, the retaining edge 2072a on the folding strip 2072 is opposite to the guide groove H20, effectively closing the open side of the guide groove H20, reliably confining the welding ribbon within the guide groove H20, and preventing the welding ribbon from detaching or shifting. This design not only improves the efficiency and convenience of welding ribbon introduction, but also ensures the stability of the welding ribbon position during the handling process, thereby helping to improve welding quality and production efficiency.

[0110] Reference Figure 8 and Figure 10 As shown, in one embodiment of the present invention, the width of the guide groove H20 gradually decreases along the conveying direction, and the opening H22 is located at the small end of the guide groove H20.

[0111] When the guide sealing plate 207 is in the closed position, the retaining edge 2072a closes the opening H22 at the small end of the guide groove H20. Compared to the large end, the small end opening H22 is smaller in area and is more easily completely closed by the retaining edge 2072a, thereby more effectively confining the welding ribbon within the guide groove H20 and preventing it from deflecting and falling out. In addition, since the width of the guide groove H20 gradually narrows along the direction of movement, once the welding ribbon enters the guide groove H20, it will be clamped between the gradually narrowing groove walls, thereby limiting the shaking and displacement of the welding ribbon within the groove, maintaining the stable position of the welding ribbon, improving the reliability and stability of the welding ribbon position in the closed state, and facilitating the precise guidance and stable handling and transfer of the welding ribbon.

[0112] Reference Figures 13 to 18 As shown, in one embodiment of the present invention, the opening H22 has two side walls opposite to each other in a first direction, the side dam portion 2072a is formed as a strip structure extending along the first direction, one end of the side dam portion 2072a is connected to one of the two side walls, and the other end of the side dam portion 2072a is defined between the other end of the side dam portion 2072a and the other of the two side walls to form the wire opening H221.

[0113] In other words, one end of the rib portion 2072a is connected to one of the side walls of the opening H22. Preferably, the rib portion 2072a and the folding strip 2072 are integrally formed. The other end of the rib portion 2072a forms a gap with the other side wall of the opening H22, and the gap constitutes the wire passing opening H221.

[0114] Through the structural design of this opening H22, when the guide sealing plate 207 is in the open position, the wire-passing opening H221 is opposite the guide groove H20, facilitating the entry of the welding ribbon into the guide groove H20 from the wire-passing opening H221. When the guide sealing plate 207 is in the closed position, the strip-shaped retaining edge 2072a is completely aligned with the open side of the guide groove H20, thereby completely sealing the open side of the guide groove H20 and reliably confining the welding ribbon within the guide groove H20, preventing it from deflecting or falling out. This structural design is not only simple in structure, but also ensures flexible and reliable switching between the two states of the opening H22, thereby ensuring the convenience and reliability of welding ribbon loading and guiding.

[0115] Preferably, the other end of the rib portion 2072a is bent downward to form a side stop 2072b. This downwardly bent side stop 2072b improves the reliability of the rib portion 2072a in sealing the guide slot H20. When the guide sealing plate 207 moves to the closed position, the strip-shaped rib portion 2072a itself seals the upper portion of the guide slot H20, while the side stop 2072b also seals one side of the opening H22, thereby completely sealing the open side of the guide slot H20 and achieving a fully reliable sealing effect.

[0116] Reference Figures 11 to 12 As shown, in one embodiment of the present invention, a guide bar 201a extending along the first direction is provided at the bottom of the guide plate 201. A limit plate 202 is provided at the bottom of the guide bar 201a. The limit plate 202 is detachably connected to the guide bar 201a via fasteners (e.g., bolts). A slide groove H21 is provided on the plate body 2071. The slide groove H21 slidably engages with the guide bar 201a, and the limit plate 202 is stopped below the plate body 2071.

[0117] A first gasket 203 is provided between the plate body 2071 and the guide plate 201 , a second gasket 204 is provided between the plate body 2071 and the limiting plate 202 , and a wear-resistant ring 205 is provided on the outer cover of the guide bar 201 a .

[0118] In this embodiment, the guide sealing plate 207 is reliably slidable in the first direction by utilizing the sliding groove H21 on the plate body 2071 and the guide bar 201a at the bottom of the guide plate 201. In order to reduce the friction between the moving pairs and improve the sliding flexibility, a first gasket 203 and a second gasket 204 are respectively provided between the plate body 2071 and the guide plate 201 and between the plate body 2071 and the limit plate 202. The first gasket 203 and the second gasket 204 can be made of a material with a low friction coefficient, which plays a lubricating role in reducing the resistance to movement. In addition, a wear-resistant ring 205 is also provided on the outside of the guide bar 201a. The material of the wear-resistant ring 205 has good wear resistance, which can effectively prevent the guide bar 201a from affecting the sliding accuracy due to wear during long-term use, and also ensure the service life.

[0119] It should be noted that the sliding design of the guide sealing plate 207 adopts the above structure instead of the traditional linear guide rail, which not only makes the structure simpler and more compact and saves space, but also makes disassembly more convenient and simple when a different guide plate 201 needs to be replaced.

[0120] Reference Figures 8 to 13As shown, in one embodiment of the present invention, there are adjustable bolts 201b on both sides of the guide plate 201 in the first direction, the axis of the adjustable bolt 201b extends along the first direction, and the position of the adjustable bolt 201b in the first direction is adjustable to limit the position of the guide sealing plate 207 in the first direction.

[0121] In order to accurately define the movement position of the guide sealing plate 207 in the first direction, especially at the open position and the closed position, adjustable bolts 201b are respectively provided on both sides of the guide plate 201 in the first direction, and the axial direction of each adjustable bolt 201b extends along the first direction, that is, the spiral movement direction of the adjustable bolt 201b is parallel to the first direction, so that the adjustable bolt 201b can adjust its own position along the first direction, and thus can accurately align with the end position of the guide sealing plate 207 in the open position and the closed position.

[0122] In actual use, the guide sealing plate 207 first needs to be moved to the accurate open position and closed position respectively, and then the adjustable bolts 201b on both sides are tightened and adjusted to the two end positions of the guide sealing plate 207, so that the end faces of the adjustable bolts 201b abut against the side faces of the guide sealing plate 207. Through this limit setting, the adjustable bolts 201b can accurately limit the travel end points of the guide sealing plate 207 in the first direction, preventing it from overtravel, thereby ensuring the accuracy of the open position and the closed position.

[0123] Illustratively, a support plate 206 is provided on one side of the guide plate 201 away from the folding strip 2072 , and the support plate 206 can support the welding strip extending from the guide groove H20 , thereby ensuring that the welding strip is more stable and orderly in the guide plate 201 .

[0124] Reference Figures 8 to 10 As shown, in one embodiment of the present invention, the ribbon guide mechanism 20 further includes a bracket 212, a lifting frame 209, and a second drive member 210. The lifting frame 209 is mounted on the bracket 212 and is slidable in the vertical direction. The second drive member 210 is mounted on the bracket 212 and is used to drive the lifting frame 209 to slide in the vertical direction. The guide plate 201 is fixed to the lifting frame 209 to move up and down with the lifting frame 209. The second drive member 210 can be a cylinder, a linear module, or the like.

[0125] In order to ensure that each welding strip is loaded into each guide groove H20, the second driving member 210 can be used to drive the lifting frame 209 to rise, so that the guide plate 201 rises accordingly and remains docked with the loading end of the welding conveyor line, so that the welding strip can be smoothly introduced into the welding conveyor line.

[0126] Through this lifting and adjusting design, the height position between the welding strip guide mechanism 20 and the welding conveyor line is accurately connected, ensuring efficient alignment during the welding strip loading and conveying process.

[0127] Reference Figure 8 and Figure 10 As shown, in one embodiment of the present invention, the lifting frame 209 has a stop portion 2091, and the bracket 212 is provided with a limiting bolt 2121. The axis of the limiting bolt 2121 extends in the up-down direction, and the height position of the limiting bolt 2121 in the up-down direction is adjustable to limit the upward movement of the stop portion 2091, that is, to limit the height position of the lifting frame 209 and the guide plate 201.

[0128] By adjusting the height of the limit bolt 2121 so that the end of the limit bolt 2121 is aligned with the target height, when the lifting frame 209 rises to this position, the stopper 2091 will contact the end of the limit bolt 2121, thereby accurately limiting the maximum travel of the lifting frame 209. This limiting design of the stopper 2091 and the limit bolt 2121 provides a simple and reliable mechanical limiting method, which can accurately control the highest position of the lifting frame 209 and the guide plate 201. At the same time, adjustment is very convenient; precise travel adjustment can be achieved by simply rotating the limit bolt 2121, which has high applicability and flexibility.

[0129] Reference Figure 19 As shown, in some embodiments of the present invention, the ribbon guiding mechanism 20 further includes a transfer mechanism 213 for driving the bracket 212 to move along the second direction, so that the ribbon guiding point can be switched at different positions.

[0130] In this embodiment, the transfer mechanism 213 is provided so that the ribbon guide mechanism 20 is no longer fixed in a certain position, but can be flexibly switched to different guide points. The advantage of this multi-point guide is that it can greatly expand the use scenarios and working conditions of the device.

[0131] In one embodiment of the present invention, the transfer mechanism 213 includes two pulleys 2131, a guide rail member 2132, a transmission belt 2133 and a reduction motor 2134. The transmission belt 2133 is connected across the two pulleys 2131. The reduction motor 2134 is connected to one of the two pulleys 2131 to drive the pulley 2131 to rotate. The bracket 212 is slidably provided on the guide rail member 2132 along the second direction and is fixed to the transmission belt 2133.

[0132] When the reduction motor 2134 begins to rotate, the transmission belt 2133 is driven by the pulley 2131, causing the bracket 212 to move in a circular motion. Because the bracket 212 is firmly connected to the transmission belt 2133, the bracket 212 also slides back and forth on the guide rail 2132. The direction of movement of the transmission belt 2133 can also change according to the forward and reverse rotation of the motor, thereby pushing the bracket 212 to move in the second direction.

[0133] By adopting the above-mentioned moving mechanism, the controllable transfer of the welding ribbon guide mechanism 20 in the second direction is realized. At the same time, this belt transmission structure has the advantages of high efficiency, stable transmission, long service life, etc., which can meet actual transfer needs.

[0134] Reference Figures 5 to 7 As shown, in some embodiments of the present invention, the welding ribbon conveying mechanism 30 includes a mounting seat 301, a sliding seat 302, a movable arm 303, a first clamping member 304, a second clamping member 305, a lifting drive device 306, a transfer drive device and a clamping claw drive device 308. The mounting seat 301 is slidable along the conveying direction, the sliding seat 302 is arranged on the mounting seat 301 and is slidable in the up and down directions, and the movable arm 303 is installed on the sliding seat 302 to rise and fall with the sliding seat 302.

[0135] The first clamping member 304 and the second clamping member 305 are arranged on the movable arm 303, and the first clamping member 304 has a plurality of first clamping fingers 3041 arranged at intervals along the first direction, and the second clamping member 305 has a plurality of second clamping fingers 3051 arranged at intervals along the first direction, the plurality of first clamping fingers 3041 correspond one to one with the plurality of second clamping fingers 3051, each of the first clamping fingers 3041 and the corresponding second clamping finger 3051 are arranged relative to each other in the first direction to form a pair of claws, and each of the claws is suitable for clamping one of the welding strips.

[0136] The lifting drive device 306 is connected to the sliding base 302 to drive the sliding base 302 to move up and down. The transfer drive device 307 is connected to the mounting base 301 to drive the mounting base 301 to slide along the conveying direction. The clamping jaw drive device 308 is connected to the first clamping member 304 and the second clamping member 305 to drive the first clamping member 304 and the second clamping member 305 to move relative to each other in the first direction, so that the clamping jaws can perform the clamping action.

[0137] The working process of the solder strip transport mechanism 30 is as follows: First, the lifting drive 306 drives the sliding seat 302 to a suitable height so that each pair of clamps is located on each solder strip. Then, the clamp drive 308 drives the first clamp 304 and the second clamp 305 to move toward each other in the first direction, and each pair of first clamp fingers 3041 and second clamp fingers 3051 closes to clamp the solder strip at the corresponding position. Furthermore, the transfer drive 307 drives the mounting seat 301 to slide along the conveying direction, driving the entire mechanism to move horizontally as a whole, and transporting the clamped solder strip from the precise position to the loading end position of the welding conveyor line 10. Finally, the clamp drive 308 drives the first clamp 304 and the second clamp 305 to move in the opposite direction in the first direction, and each pair of first clamp fingers 3041 and second clamp fingers 3051 opens to release the solder strip. The lifting drive device 306 drives the sliding seat 302 to rise, and then drives the mounting seat 301 to slide in the opposite direction of the conveying direction through the transfer drive device 307. This cycle is repeated to realize the orderly transportation and transfer of the welding strip to the welding conveyor line.

[0138] The aforementioned welding handling mechanism accurately and efficiently transports the solder ribbon to the welding conveyor line 10 each time. Furthermore, through the lifting and lowering of the sliding seat 302 and the horizontal movement of the mounting seat 301, the solder ribbon can be accurately positioned in the desired three-dimensional space, ensuring high-precision coordination with the solder ribbon guide mechanism 20 and the welding conveyor line. Furthermore, multiple pairs of jaws clamp from top to bottom, preventing the solder ribbon from tilting upward when clamped. This enables precise, efficient, and flexible handling, improves the accuracy of the positioning and alignment of the solder ribbon and the cell grid lines on the welding conveyor line, and reduces weld defects.

[0139] Reference Figure 7 As shown, in one embodiment of the present invention, the clamping jaw driving device 308 includes a first pivot rod 3081, a first driving cylinder 3082, a second pivot rod 3083 and a second driving cylinder 3084, and the first clamping member 304 and the second clamping member 305 are slidably provided on the movable arm 303.

[0140] The middle part of the first pivot rod 3081 is pivotally connected to the movable arm 303, and the first driving cylinder 3082 is connected to one end of the first pivot rod 3081 to drive the first pivot rod 3081 to rotate, so as to push the first clamping member 304 to slide through the other end of the first pivot rod 3081.

[0141] The middle part of the second pivot rod 3083 is pivotally connected to the movable arm 303, and the second driving cylinder 3084 is connected to one end of the second pivot rod 3083 to drive the second pivot rod 3083 to rotate, so as to push the second clamping member 305 to slide through the other end of the second pivot rod 3083.

[0142] When the jaws need to be opened, the first drive cylinder 3082 and the second drive cylinder 3084 retract simultaneously, driving the first pivot rod 3081 and the second pivot rod 3083 to rotate respectively, thereby pushing the first clamping member 304 and the second clamping member 305 to slide outward, causing the first clamping finger 3041 and the second clamping finger 3051 to move away from each other, thereby achieving the jaws opening. When the jaws need to be closed, the first drive cylinder 3082 and the second drive cylinder 3084 extend simultaneously, driving the first pivot rod 3081 and the second pivot rod 3083 to rotate in opposite directions, causing the first clamping member 304 and the second clamping member 305 to slide inward, causing the first clamping finger 3041 and the second clamping finger 3051 to move together, thereby achieving the jaws closing and clamping.

[0143] In this embodiment, the first pivot rod 3081 and the second pivot rod 3083 are driven to rotate by the first drive cylinder 3082 and the second drive cylinder 3084, respectively, to achieve relative sliding of the first clamping member 304 and the second clamping member 305 along a first direction on the movable arm 303. This allows the first clamping member 304 and the second clamping member 305 to open and close, respectively, thereby clamping the welding strips. The design of the clamping jaw drive device 308 features a compact structure and a direct and efficient transmission process, making it suitable for installation on the movable arm 303, where space is limited. This improves the controllability and stability of the clamping, and provides a strong guarantee for the synchronous clamping of the individual welding strips.

[0144] Reference Figures 20 to 22 As shown, in some embodiments of the present invention, the welding ribbon clamping mechanism 40 includes a fixed seat 401, a plurality of clamping claws 402, a plurality of elastic members 403, two toggle plates 404 and a synchronous drive device 405, and the fixed seat 401 can be fixed at one end of the conveying rack 101.

[0145] Multiple clamping jaws 402 are spaced apart along the first direction on the fixed base 401. Each clamping jaw 402 comprises two pivotally connected clamping legs 4021, each having a clamping end D41 and a driving end D42. Because the two clamping legs 4021 are pivotally connected, they can rotate about the pivot point to open and close relative to each other. The clamping end D41 of each clamping leg 4021 is used to clamp the welding ribbon, while the driving end D42 acts as the site of action for the toggle plate 404 and elastic member 403 to drive the relative rotation of the two clamping legs 4021.

[0146] The plurality of elastic members 403 correspond one-to-one with the plurality of clamping jaws 402. Each elastic member 403 is positioned between the driving ends D42 of the two clamping legs 4021 of a corresponding clamping jaw 402, thereby maintaining the clamping ends D41 of the two clamping legs 4021 in close proximity. The elastic member 403 serves to reset the clamping jaw 402. In the absence of external force, the elastic member 403 keeps the two clamping legs 4021 closed, thereby clamping the soldering ribbon. This elastic clamping of the soldering ribbon allows the soldering ribbon to be accurately positioned while also being pulled along the conveying direction by the soldering ribbon transport mechanism 30.

[0147] Each of the toggle plates 404 has a number of shifting teeth 4041 equal to the number of the clamping members 402. The shifting teeth 4041 on one of the toggle plates 404 are located outside the driving end D42 of one clamping foot 4021 of the corresponding clamping member 402, and the shifting teeth 4041 on the other toggle plate 404 are located outside the driving end D42 of the other clamping foot 4021 of the corresponding clamping member 402. In other words, a corresponding pair of shifting teeth 4041 on two toggle plates 404 corresponds to one clamping member 402, and the two clamping feet 4021 of the clamping member 402 are located between the pair of shifting teeth 4041, thereby driving the opening and closing movement of the two clamping feet 4021 through the two shifting teeth 4041.

[0148] The synchronous drive device 405 is used to drive the two toggle plates 404 to move toward each other, so that the toggle teeth push the clamping ends D41 of the two clamping feet 4021 of the clamping claw member 402 away and switch to the open state, and drive the two toggle plates 404 to move in the opposite direction, so that the elastic member 403 is reset, and the clamping ends D41 of the two clamping feet 4021 are restored to the close state.

[0149] When the clamping jaws 402 need to be opened, the synchronous drive device 405 drives the two toggle plates 404 to move toward each other. The teeth 4041 on the toggle plates 404 push the driving ends D42 of the two clamping feet 4021 of the clamping jaws 402 toward each other. The two clamping feet 4021 rotate, causing the clamping ends D41 of the two clamping feet 4021 to move away from each other, thereby switching to the open state and releasing the solder strip. During this process, the elastic member 403 is compressed. When the clamping jaws 402 need to be closed, the synchronous drive device 405 drives the two toggle plates 404 to move in the opposite direction. The teeth 4041 on the toggle plates 404 no longer push the clamping feet 4021, and the elastic member 403 resets, forcing the driving ends D42 of the two clamping feet 4021 to move away from each other, while the clamping ends D41 return to the closed state, thereby clamping the solder strip.

[0150] In this embodiment, the ribbon clamping mechanism 40 controls the opening and closing of the clamping jaw 402 by toggling the driving end D42 of the clamping foot 4021 of the clamping jaw 402 with a toggle plate 404. The resetting action of the elastic member 403 maintains the clamping jaw closed in the absence of external force. This mechanism features a compact design, flexible and controllable opening and closing, and the elastic action of the elastic member 403 achieves clamping, ensuring reliable positioning while allowing the ribbon to be transported by the ribbon transport mechanism 30. The synchronous drive device 405 synchronizes the movement of the multiple clamping jaws 402, ensuring that each ribbon can be smoothly and reliably clamped and released, meeting the requirements for ribbon clamping during welding operations.

[0151] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
