Description

Technical Field

[0001] This application belongs to the field of photovoltaic module manufacturing technology, specifically, it relates to a welding strip arrangement and handling device. Background Technology

[0002] Currently, the main production method for photovoltaic modules involves alternating the arrangement of individual solar cells and single-strand solder ribbons, which has low production efficiency. Another method uses a single machine to arrange the entire sheet of solar cells before transferring them to the next machine for solder ribbon arrangement. In the solder ribbon arrangement process for back-contact solar cells, two solder ribbon arrangement stations are set up. The entire sheet of solar cells is transferred to one station, where odd-numbered solder ribbons are arranged on the adhesive layer of the solar cell or backsheet. Then it is transferred to the other station, where even-numbered solder ribbons are arranged on the adhesive layer of the solar cell or backsheet. This method of separately handling and arranging odd-numbered and even-numbered solder ribbons is inefficient, has poor stability in solder ribbon arrangement, is costly, and occupies a large space. Utility Model Content

[0003] In view of this, this application provides a solder strip arrangement and handling device, which allows odd-numbered and even-numbered solder strips to be arranged on the adhesive layer of the battery cell or backsheet at the same solder strip arrangement station.

[0004] A welding strip arrangement and handling device includes a first power output component and a plurality of clamping modules arranged in parallel along the extension direction of the welding strip. Each clamping module includes at least four clamping components arranged along the extension direction of the welding strip. Each clamping component includes a plurality of gripper units arranged in a direction perpendicular to the extension direction of the welding strip. The first power output component drives the gripper units to clamp or release the welding strip.

[0005] The gripping components of each gripping module cooperate with each other so that at least the two ends of the odd-numbered solder strips and the two ends of the even-numbered solder strips can be gripped or released by the corresponding gripper units.

[0006] Preferably, each of the clamping modules includes a base, and along the extension direction of the welding strip, each base is provided with four clamping components, wherein two clamping components are located on both sides of the base and the other two clamping components are located in the middle of the base.

[0007] Along the extension direction of the weld strip, the clamping components on both sides of each base cooperate to clamp or release the two ends of an odd number of weld strips. For the outermost clamping module, its outermost clamping component cooperates with another adjacent clamping component to clamp or release the two ends of an even number of weld strips.

[0013] Preferably, the limiting member includes a first limiting rod and a second limiting rod mounted on the base in a direction perpendicular to the extension direction of the welding strip, and a gap for accommodating the welding strip is formed between the first limiting rod and the second limiting rod;

[0014] When the solder strip is released, it falls along the gap.

[0015] Preferably, it also includes a pressing module, which includes a second power output component, a first pressing component, a second pressing component, and a third pressing component, wherein the second power output component drives the first pressing component, the second pressing component, and the third pressing component to move up and down;

[0016] Along the extension direction of the welding strip, the first pressing component is located between two clamping components in the middle of the base. Each base has a second pressing component on each side. Two adjacent clamping modules share a second pressing component. In the outermost clamping module, a third pressing component is provided between the outermost second pressing component and the adjacent first pressing component.

[0017] When the solder strips are released, the middle of each odd-numbered solder strip is pressed by the corresponding first pressing component. Along the extension direction of the solder strips, the middle of each outermost even-numbered solder strip is pressed by the corresponding third pressing component, and the middle of each middle even-numbered solder strip is pressed by the corresponding second pressing component. Then, each gripper unit releases the solder strips, and then the end of each odd-numbered solder strip is pressed by the corresponding second pressing component. Along the extension direction of the solder strips, the two ends of each outermost even-numbered solder strip are pressed by the first pressing component and the second pressing component on both sides of the corresponding third pressing component, respectively, and the end of each middle even-numbered solder strip is pressed by the corresponding first pressing component.

[0018] Preferably, the first pressing assembly includes a first mounting plate and two first pressing units arranged side by side on the first mounting plate along the extension direction of the welding strip;

[0021] Along the extension direction of the solder strip, each first pressing unit and each intermediate second pressing unit include multiple first pressing portions and second pressing portions arranged alternately in a direction perpendicular to the extension direction of the solder strip. The outermost second pressing unit includes multiple second pressing portions arranged alternately in a direction perpendicular to the extension direction of the solder strip. Both the first pressing portions and the second pressing portions are elastic, and the length of the first pressing portion is greater than the length of the second pressing portion. Specifically, the first pressing portions in the first pressing unit are positioned opposite the middle of the odd-numbered solder strips, and the second pressing portions in the first pressing unit are positioned opposite the ends of the even-numbered solder strips. The outermost second pressing portion... Each second pressing part in the pressing unit is positioned opposite the corresponding odd-numbered or even-numbered solder strip end.

Each third pressing part is elastic, and its length is greater than the length of the second pressing parts. Each third pressing part is positioned opposite the middle of the outermost even-numbered solder strip. Each first pressing part, second pressing part, and third pressing part corresponds to one solder strip.

[0022] When the welding strip is released, the second power output unit drives the first mounting plate, the second mounting plate and the third mounting plate to move downward until each of the first pressing parts and each of the third pressing parts presses down the middle of the corresponding welding strip. Then each gripper unit releases the welding strip, and the second power output unit continues to drive the first mounting plate, the second mounting plate and the third mounting plate to move downward, so that each of the first pressing parts and each of the third pressing parts is compressed until each of the second pressing parts presses down the end of the corresponding welding strip.

All the upper gripping parts corresponding to each clamping assembly are mounted on the same upper mounting plate in a direction perpendicular to the extension direction of the welding strip, and all the lower gripping parts corresponding to each clamping assembly are mounted on the same lower mounting plate in a direction perpendicular to the extension direction of the welding strip.

[0025] When clamping the welding strip, the first power output component drives the lower mounting plate to move laterally, so that all the lower clamping parts on the lower mounting plate move simultaneously from the side below the corresponding welding strip to below the welding strip, and can drive the upper mounting plate to move downward, so that all the upper clamping parts on the upper mounting plate move downward simultaneously, until each upper clamping part presses the welding strip below it onto the lower clamping part below the welding strip.

[0026] When the welding strip is released, the first power output component drives the upper mounting plate to move upward, causing all the upper clamping parts on the upper mounting plate to move upward simultaneously, and can also drive the lower mounting plate to move laterally, so that all the lower clamping parts on the lower mounting plate move simultaneously from below the corresponding welding strip to the side below the welding strip.

[0027] Preferably, a cam follower is mounted on the upper mounting plate, and a guide groove is provided on the lower mounting plate, with the upper part of the guide groove inclined and the lower part of the guide groove vertically arranged;

[0028] When the welding strip is gripped, the first power output component drives the upper mounting plate to move downward, and the cam follower moves from the upper end to the lower end of the guide groove, so that the lower gripping part moves from the side below the welding strip to below the welding strip. At the same time, the upper gripping part moves downward until the upper gripping part presses the welding strip onto the lower gripping part below the welding strip.

[0029] When the welding strip is released, the first power output component drives the upper mounting plate to move upward, and the cam follower moves from the lower end to the upper end of the guide groove, causing the upper clamping part to move upward, while the lower clamping part moves from below the welding strip to the side below the welding strip.

[0030] Preferably, when clamping or releasing the welding strip, the upper mounting plate is guided by a vertical guide element, and the lower mounting plate is guided by a horizontal guide element.

Detailed Implementation

[0042] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] 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.

[0044] This application provides a welding strip arrangement and handling device, with reference to... Figure 1-7 It includes a first power output component 2 and a plurality of clamping modules 3 arranged in parallel along the extension direction of the welding strip 1. Each clamping module 3 includes at least four clamping components 32 arranged along the extension direction of the welding strip 1. Each clamping component 32 includes a plurality of gripper units 321 arranged in a direction perpendicular to the extension direction of the welding strip 1. The first power output component 2 drives the gripper units 321 to clamp or release the welding strip 1.

[0045] Each clamping component 32 of each clamping module 3 cooperates with each other, so that at least the two ends of the odd number of solder strips 11 and the two ends of the even number of solder strips 12 can be clamped or released by the corresponding gripper unit 321.

[0046] The solder strips 1 arranged on the solar cell include odd-numbered solder strips 11 and even-numbered solder strips 12. The odd-numbered solder strips 11 refer to the solder strips located in odd positions along the direction perpendicular to the extension direction of the solder strip, and the even-numbered solder strips 12 refer to the solder strips located in even positions along the direction perpendicular to the extension direction of the solder strip.

[0047] In a preferred embodiment, the number of clamping modules 3 is the same as the number of cells in a battery string of a photovoltaic module. This allows the multiple clamping modules 3 to cooperate in clamping or releasing all odd-numbered solder strips 11 and even-numbered solder strips 12 corresponding to a battery string, ensuring that all these solder strips are arranged on the corresponding cells or the adhesive layer of the backsheet. It is understood that each cell comprises two halves. In a further preferred embodiment, the first power output unit 2 can drive all the gripper units 321 in all the clamping modules 3 to simultaneously clamp or release the solder strips 1, thereby ensuring that all odd-numbered solder strips 11 and even-numbered solder strips 12 corresponding to each cell in a battery string are simultaneously clamped or released.

[0048] It is understood that the extension direction of the solder strip 1 in this application refers to the length direction of a battery string, and the direction perpendicular to the extension direction of the solder strip 1 refers to the width direction of a battery string.

[0049] This application requires only one solder ribbon arrangement station to arrange odd-numbered solder ribbons 11 and even-numbered solder ribbons 12 on the adhesive layer of the battery cell or backsheet, thereby reducing equipment space and cost, and improving the accuracy and stability of solder ribbon arrangement. Preferably, in this embodiment, odd-numbered solder ribbons 11 and even-numbered solder ribbons 12 are arranged simultaneously on the battery cell.

[0050] In a preferred embodiment, refer to Figure 2-4 Each clamping module 3 includes a base 31. Along the extension direction of the welding strip 1, each base 31 is provided with four clamping components 32, of which two clamping components 32 are located on both sides of the base 31 and the other two clamping components 32 are located in the middle of the base 31.

[0051] Along the extension direction of the welding strip 1, the clamping components 32 on both sides of each base 31 cooperate to clamp or release the two ends of the odd number of welding strips 11. For the outermost clamping module 3, its outermost clamping component 32 cooperates with another adjacent clamping component 32 to clamp or release the two ends of the even number of welding strips 12. For the middle clamping module 3, the two clamping components 32 that are close to each other in the middle of two adjacent bases 31 cooperate to clamp or release the two ends of the even number of welding strips 12.

[0052] It is understood that, in this embodiment, the outermost edge refers to the beginning or end of the welding strip arrangement and conveying device along the length of the battery string, i.e. Figure 2The leftmost or rightmost one.

[0053] During the process of the first power output component 2 driving all the gripper units 321 in all the gripping modules 3 to simultaneously grip the welding strips 1, one end of each odd-numbered welding strip 11 is gripped by the corresponding gripper unit 321 in the gripping assembly 32 on one side of the base 31, and the other end is gripped by the corresponding gripper unit 321 in the gripping assembly 32 on the other side of the base 31; one end of each even-numbered welding strip 12 on the outermost side is gripped by the corresponding gripper unit 321 in the outermost gripping assembly 32, and the other end is gripped by the corresponding gripper unit 321 in the gripping assembly 32 on the other side of the base 31. The outermost gripping component 32 is gripped by the corresponding claw unit 321 in the adjacent gripping component 32; one end of each even-numbered solder strip 12 in the middle (i.e., the even-numbered solder strips 12 other than the outermost even-numbered solder strip 12) is gripped by the corresponding claw unit 321 in the gripping component 32 in the middle of one of the bases 31, and the other end is gripped by the corresponding claw unit 321 in the gripping component 32 of the gripping module 3 in the middle of the adjacent base 31 near the one end of the solder strip 1.

[0054] In this embodiment, each gripper unit 321 grips one welding strip 1.

[0055] In another embodiment, each clamping module 3 may include two bases 31 (not shown in the figure). Along the extension direction of the solder strip 1, each base 31 is provided with two clamping components 32. The two clamping components 32 on two adjacent bases 31 that are far apart from each other cooperate to clamp the two ends of the odd number of solder strips 11. The two clamping components 32 on the outermost base 31 cooperate to clamp the two ends of the outermost even number of solder strips 12. The two clamping components 32 on two adjacent bases 31 in the middle that are far apart from each other cooperate to clamp the two ends of the middle even number of solder strips 12.

[0056] Preferably, this embodiment uses a base 31 with four gripping components 32. For better description of this embodiment, the following description will use a base 31 with four gripping components 32.

[0057] refer to Figure 3 Along the extension direction of the welding strip 1, the number of gripper units 321 in each of the middle gripping components 32 is half the number of gripper units 321 in the outermost gripping component 32.

[0058] Typically, the number of odd-numbered solder strips 11 is the same as the number of even-numbered solder strips 12 in the width direction of the battery string. In order for the solder strip arrangement and handling device to be able to grip all the odd-numbered solder strips 11 and even-numbered solder strips 12 corresponding to a battery string, in this embodiment, the number of gripper units 321 in the outermost gripping component 32 is the same as the total number of odd-numbered solder strips 11 and even-numbered solder strips 12 that need to be arranged in a single half-piece, and the number of gripper units 321 in each of the middle gripping components 32 is the total number of odd-numbered solder strips 11 or the total number of even-numbered solder strips 12 that need to be arranged in a single half-piece. For example, if a single half-piece requires a total of 20 solder strips 1, with 10 odd-numbered solder strips 11 and 10 even-numbered solder strips 12, then the outermost clamping assembly 32 has 20 clamping units 321, and each middle clamping assembly 32 has 10 clamping units 321. Furthermore, the clamping units 321 in the two clamping assemblies 32 in the middle of each base 31 are arranged in a one-to-one correspondence and on the same horizontal line. Except for the outermost clamping assembly 32, the clamping units 321 in each clamping assembly 32 in the middle of each base 31 are staggered with the clamping units 321 in the clamping assembly 32 on one side of the base 31. The clamping units 321 in the two adjacent clamping assemblies 32 in two adjacent bases 31 are arranged in a one-to-one correspondence and on the same horizontal line, thus enabling the clamping units 321 to cooperate in clamping both ends of each odd-numbered solder strip 11 and both ends of each even-numbered solder strip 12.

[0059] Photovoltaic modules consist of positive electrode strings and negative electrode strings. The current flows in opposite directions in the positive and negative electrode strings because the structures of the solder ribbon strings that need to be arranged on the positive electrode string and the solder ribbon strings that need to be arranged on the negative electrode string are different. For example, the solder ribbon strings that need to be arranged on the positive electrode string are denoted as solder ribbon string A, and the solder ribbon strings that need to be arranged on the negative electrode string are denoted as solder ribbon string B. Solder ribbon strings A and solder ribbon strings B are mirror images of each other.

[0060] In order to enable the welding strip arrangement and conveying device to handle both welding strip string A and welding strip string B, in a further preferred embodiment, along the extension direction of the welding strip, the number of gripper units 321 in the outermost gripping assembly 32 is 2a+1, the number of gripper units 321 in each of the remaining gripping assemblies 32 located on the side of the base 31 is a+1, and the number of gripper units 321 in each of the gripping assemblies 32 located in the middle of the base 31 is a; or, the number of gripper units 321 in each of the remaining gripping assemblies 32 located on the side of the base 31 is a, and the number of gripper units 321 in each of the gripping assemblies 32 located in the middle of the base 31 is a+1.

[0061] If a set of gripper units 321 (referring to gripper units 321 located on the same straight line along the extension direction of the welding strip 1) is added to transport an odd number of welding strips 11, so that the welding strip transport device can transport both welding strip A and welding strip B, then the number of gripper units 321 in the outermost gripping assembly 32 can be set to 2a+1, the number of gripper units 321 in each gripping assembly 32 located on the side of the base 31 can be set to a+1, and the number of gripper units 321 in each gripping assembly 32 located in the middle of the base 31 can be set to a.

[0062] If a set of gripper units 321 for handling an even number of welding strips 12 is added (referring to gripper units 321 located on the same straight line along the extension direction of welding strip 1), so that the welding strip handling device can handle both welding strip string A and welding strip string B, then the number of gripper units 321 in the outermost gripping assembly 32 can be set to 2a+1, the number of gripper units 321 in each gripping assembly 32 located on the side of the base 31 can be set to a, and the number of gripper units 321 in each gripping assembly 32 located in the middle of the base 31 can be a+1.

[0063] The above design enables the welding strip handling device of this application to handle both welding strip string A and welding strip string B.

[0064] Furthermore, 2a can be the number of solder strips 1 that need to be arranged in a single half-piece.

[0065] refer to Figure 3-5 To prevent the position of the solder strip 1 from shifting during the release of the solder strip 1 by each gripper unit 321, this embodiment provides a limiting component near each gripping component 32. Each limiting component includes multiple limiting members 4 arranged in a direction perpendicular to the extension direction of the solder strip. Along the extension direction of the solder strip, at least one limiting member 4 is provided near each gripper unit 321, so that during the release of the solder strip 1, at least both ends of each solder strip 1 are limited by the limiting member 4, thereby ensuring that the position of the solder strip 1 falling onto the grid line of the battery cell will not shift.

[0066] In a preferred embodiment, along the extension direction of the solder strip 1, the number of limiting members 4 in each limiting assembly is the same as the number of gripper units 321 in the outermost gripping assembly 32. That is, the number of limiting members in each limiting assembly is the total number of odd-numbered solder strips 11 and even-numbered solder strips 12 that need to be arranged in a single half piece. This ensures that when the solder strip 1 is released, each odd-numbered solder strip 11 is limited by four limiting members 4, each outermost even-numbered solder strip 12 is limited by two limiting members 4, and each middle even-numbered solder strip 12 is limited by four limiting members 4.

[0067] like Figure 3As shown, the outermost even-numbered welding strips 12 are shorter than the other odd-numbered welding strips 11 and even-numbered welding strips 12. Therefore, each outermost even-numbered welding strip 12 can be limited by two limiting members 4 to ensure that the welding strip 1 falls accurately. However, for the other longer odd-numbered welding strips 11 and even-numbered welding strips 12, four limiting members 4 are needed to limit them to ensure that the welding strip 1 falls accurately.

[0068] In a further preferred embodiment, the limiting member 4 includes a first limiting rod 41 and a second limiting rod 42 mounted on the base 31 in a direction perpendicular to the extension direction of the welding strip 1. A gap is formed between the first limiting rod 41 and the second limiting rod 42 to accommodate the welding strip 1. When the welding strip 1 is released, the first limiting rod 41 and the second limiting rod 42 press on the battery cell, and the welding strip 1 falls along the gap, thereby limiting the position of the falling welding strip 1 and ensuring that the welding strip 1 can fall on the grid line of the corresponding battery cell.

[0069] In this embodiment, the first limiting rod 41 and the second limiting rod 42 can be a probe structure or other elastic structures. Alternatively, the parts of the first limiting rod 41 and the second limiting rod 42 that contact the battery cell can be made of elastic material. This embodiment does not make specific limitations on this, as long as the first limiting rod 41 and the second limiting rod 42 can elastically press against the battery cell before each gripper unit 321 releases the solder strip 1, without damaging the battery cell.

[0070] To further ensure that the position of the solder ribbons 1 on the solar cell does not shift, i.e., to ensure that each solder ribbon 1 falls on the corresponding grid line of the solar cell, refer to... Figure 3-4 The welding strip arrangement and conveying device in this embodiment also includes a pressing module 5. The pressing module 5 includes a second power output component 51, a first pressing component 52, a second pressing component 53 and a third pressing component 54. The second power output component 51 drives the first pressing component 52, the second pressing component 53 and the third pressing component 54 to move up and down.

[0071] Along the extension direction of the welding strip 1, the first pressing component 52 is located between the two clamping components 32 in the middle of the base 31. Each base 31 has a second pressing component 53 on both sides. Two adjacent clamping modules 3 share a second pressing component 53. In the outermost clamping module 3, a third pressing component 54 is provided between the outermost second pressing component 53 and the adjacent first pressing component 52.

[0072] When the solder strip 1 is released, the middle of each odd-numbered solder strip 11 is pressed by the corresponding first pressing component 52. Along the extension direction of the solder strip 1, the middle of each outermost even-numbered solder strip 12 is pressed by the corresponding third pressing component 54, and the middle of each middle even-numbered solder strip 12 is pressed by the corresponding second pressing component 53. Then each gripper unit 321 releases the solder strip 1, and then the end of each odd-numbered solder strip 11 is pressed by the corresponding second pressing component 53. Along the extension direction of the solder strip 1, the two ends of each outermost even-numbered solder strip 12 are pressed by the first pressing component 52 and the second pressing component 53 on both sides of the corresponding third pressing component 54, and the end of each middle even-numbered solder strip 12 is pressed by the corresponding first pressing component 52.

[0073] After the required staggered arrangement of odd-numbered welding strips 11 and even-numbered welding strips 12 is produced at the welding strip production station, each gripper unit 321 in each gripping component 32 of the welding strip arrangement and transportation device grips all the odd-numbered welding strips 11 and even-numbered welding strips 12 and transports them to the welding strip arrangement station, and then releases the welding strip 1. During this process, the middle portion of each odd-numbered solder strip 11 is pressed onto the grid line of the battery cell by the first pressing component 52. Along the extension direction of the solder strip 1, the middle portion of each outermost even-numbered solder strip 12 is pressed onto the grid line of the battery cell by the third pressing component 54, and the middle portion of each even-numbered solder strip 12 in the middle is pressed onto the grid line of the battery cell by the second pressing component 53. Then, each gripper unit 321 releases the solder strip 1, causing all odd-numbered solder strips 11 and even-numbered solder strips 12 to fall onto the grid line of the battery cell. Finally, the ends of each odd-numbered solder strip 11 are pressed onto the grid line of the battery cell by the second pressing component 53, and the ends of each even-numbered solder strip 12 in the middle are pressed onto the grid line of the battery cell. Both ends of the strip 12 are pressed onto the grid lines of the battery cell by the first pressing component 52 and the second pressing component 53 on both sides of the third pressing component 54, respectively. The ends of each even-numbered strip 12 in the middle are pressed onto the grid lines of the battery cell by the first pressing unit 52. Thus, during the release of the strip 1, after each odd-numbered strip 11 and each even-numbered strip 12 is pressed onto the grid lines of the battery cell in the middle, each gripper unit 321 is released, and then the ends of each odd-numbered strip 11 and the ends of each even-numbered strip 12 are pressed onto the grid lines of the battery cell to ensure that each strip 1 can be accurately arranged on the corresponding grid lines of the battery cell.

[0074] For details, please refer to Figure 3-4 The first pressing assembly 52 includes a first mounting plate 521 and two first pressing units 522 arranged side by side on the first mounting plate 521 along the extension direction of the welding strip 1;

[0075] The second pressing assembly 53 includes a second mounting plate 531 and a second pressing unit 532 disposed on the second mounting plate 531. Along the extension direction of the welding strip 1, the outermost second pressing assembly 53 has a second pressing unit 532 disposed on the second mounting plate 531, and each of the middle second pressing assemblies 53 has two second pressing units 532 disposed side by side on the second mounting plate 531.

[0076] The third pressing assembly 54 includes a third mounting plate 541 and a third pressing unit 542 disposed on the third mounting plate 541;

[0077] Along the extension direction of the solder strip 1, each first pressing unit 522 and each intermediate second pressing unit 532 includes multiple first pressing portions 55 and second pressing portions 56 arranged alternately in a direction perpendicular to the extension direction of the solder strip 1. The outermost second pressing unit 532 includes multiple second pressing portions 56 arranged in a direction perpendicular to the extension direction of the solder strip 1. Both the first pressing portions 55 and the second pressing portions 56 are elastic, and the length of the first pressing portion 55 is greater than the length of the second pressing portion 56. Specifically, the first pressing portions 55 in the first pressing unit 522 are positioned opposite the middle of the odd-numbered solder strips 11, and the second pressing portions 56 in the first pressing unit 522 are positioned opposite the ends of the even-numbered solder strips 12. The outermost second pressing unit 532... Each of the second pressing portions 56 in the middle is positioned opposite the end of the corresponding odd-numbered solder strip 11 or the end of the even-numbered solder strip 12. The first pressing portion 55 in each of the middle second pressing units 532 is positioned opposite the middle of the even-numbered solder strip 12, and the second pressing portion 56 in each of the middle second pressing units 532 is positioned opposite the end of the odd-numbered solder strip 11. The third pressing unit 542 includes a plurality of third pressing portions 57 positioned along a direction perpendicular to the extension direction of the solder strip 1. The third pressing portions 57 are elastic, and their length is greater than the length of the second pressing portions 56. The third pressing portions 57 are positioned opposite the middle of the outermost even-numbered solder strip 12. Furthermore, each of the first pressing portion 55, the second pressing portion 56, and the third pressing portion 57 is positioned opposite one solder strip 1.

[0078] When the welding strip 1 is released, the second power output unit 51 drives the first mounting plate 521, the second mounting plate 531 and the third mounting plate 541 to move downward until each first pressing part 55 and each third pressing part 57 presses down the middle of the corresponding welding strip 1. Then each gripper unit 321 releases the welding strip 1. The second power output unit 51 continues to drive the first mounting plate 521, the second mounting plate 531 and the third mounting plate 541 to move downward, so that each first pressing part 55 and each third pressing part 57 are compressed until each second pressing part 56 presses down the end of the corresponding welding strip 1.

[0079] The first pressing part 55, the second pressing part 56, and the third pressing part 57 can be a probe structure, a spring, or made of flexible materials such as sponge or silicone. As long as the first pressing part 55, the second pressing part 56, and the third pressing part 57 do not damage the solder ribbon 1 and the battery cell when pressing the solder ribbon 1 onto the grid line of the battery cell, it is acceptable.

[0080] The lengths of the first pressing part 55 and the third pressing part 57 can be the same or different, as long as the lengths of the first pressing part 55 and the third pressing part 57 are both greater than the length of the second pressing part 56, and the length difference between the first pressing part 55, the third pressing part 57 and the second pressing part 56 is sufficient to allow the second pressing part 56 to press the welding strip 1 onto the grid line of the battery cell after the first pressing part 55 and the third pressing part 57 are compressed to a certain extent.

[0081] The second power output component 51 can drive the first mounting plate 521, the second mounting plate 531 and the third mounting plate 541 to move up and down simultaneously, or they can move up and down at different times. As long as the middle part of each welding strip 1 is pressed onto the grid line of the battery cell by the corresponding first pressing part 55 or the third pressing part 57, the gripper unit 321 releases the welding strip 1, and then the two ends of each welding strip 1 are pressed onto the grid line of the battery cell by the corresponding second pressing part 56.

[0082] In this embodiment, the second power output component 51 can be a cylinder, which drives the first mounting plate 521, the second mounting plate 531, and the third mounting plate 541 to move up and down. For example, only one cylinder is provided, and all the first mounting plates 521, all the second mounting plates 531, and all the third mounting plates 541 are mounted on a transition rod. The cylinder drives the transition rod to move up and down, thereby causing all the first mounting plates 521, all the second mounting plates 531, and all the third mounting plates 541 to move up and down simultaneously.

[0083] In this embodiment, during the release of the solder strips 1, each solder strip 1 can be accurately arranged on the grid line of the battery cell, thereby improving the subsequent welding accuracy.

[0084] It is understood that, along the extension direction of the solder strip 1, the number of second pressing portions 56 in the outermost second pressing unit 532 is the same as the total number of odd-numbered solder strips 11 and even-numbered solder strips 12 required to be arranged in a single half-piece. The number of first pressing portions 55 and second pressing portions 56 in each of the remaining second pressing units 532 is the same as the total number of odd-numbered solder strips 11 or even-numbered solder strips 12 required to be arranged in a single half-piece. The number of first pressing portions 55 and second pressing portions 56 in each first pressing unit 522 and the number of third pressing portions 57 in each third pressing unit 542 are the same as the total number of odd-numbered solder strips 11 or even-numbered solder strips 12 required to be arranged in a single half-piece. For example, if a single half-piece needs to be arranged with 10 odd-numbered solder strips 11 and 10 even-numbered solder strips 12, then the number of second pressing parts 56 in the outermost second pressing unit 532 is 20, the number of first pressing parts 55 and second pressing parts 56 in each of the remaining second pressing units 532 is 10, the number of first pressing parts 55 and second pressing parts 56 in each first pressing unit 522 and the number of third pressing parts 57 in each third pressing unit 542 are 10.

[0085] If the welding strip handling device of this application needs to handle both welding strip string A and welding strip string B, then the number of second pressing parts 56 in the outermost second pressing unit 532 is 2a+1. Wherein, if the number of gripper units 321 in each of the remaining gripping assemblies 32 located on the side of the base 31 is a+1, then the number of first pressing parts 55 in each first pressing unit 522 is a+1, the number of second pressing parts 56 in each first pressing unit 522 is a, the number of first pressing parts 55 in each intermediate second pressing unit 532 is a, the number of second pressing parts 56 in each intermediate second pressing unit 532 is a+1, and the number of third pressing parts 57 in each third pressing unit 542 is a. If the number of gripper units 321 in each gripping assembly 32 located in the middle of the base 31 is a+1, then the number of first pressing parts 55 in each first pressing unit 522 is a, the number of second pressing parts 56 in each first pressing unit 522 is a+1, the number of first pressing parts 55 in each middle second pressing unit 532 is a+1, the number of second pressing parts 56 in each middle second pressing unit 532 is a, and the number of third pressing parts 57 in each third pressing unit 542 is a+1. Through the above design, regardless of whether the A-strand or B-strand is arranged, each strip 1 is pressed onto the battery cell in the middle before the gripper unit 321 is released, and then the end of each strip 1 is pressed onto the battery cell. Since the length of the outermost even-numbered solder strips 12 is shorter than that of the other even-numbered solder strips 12 along the extension direction of the solder strips 1, in order to ensure that the middle portion of the outermost even-numbered solder strips 12 can be pressed onto the grid lines of the battery cell before the solder strips 1 are released, this embodiment provides a third pressing unit 542 between the outermost second pressing unit 532 and the adjacent first pressing unit 522, so that the outermost even-numbered solder strips 12 can be pressed onto the grid lines of the battery cell by the third pressing unit 542 before the solder strips 1 are released. Furthermore, the number of second pressing portions 56 in the outermost second pressing unit 532 is the same as the total number of solder strips 1 required for a single half-cell, such that one end of each of the outermost odd-numbered solder strips 11 and even-numbered solder strips 12 is pressed by the corresponding second pressing portion 56 in the outermost second pressing unit 532.

[0086] In a further preferred embodiment, refer to Figure 3-4 Each first mounting plate 521 and each second mounting plate 531 has an irradiation section 6 on the side facing the welding strip 1 in a direction perpendicular to the extension direction of the welding strip 1.

[0087] Before the solar cells are conveyed to the ribbon placement station, adhesive is applied to the preset positions of each grid line of the solar cells. After each ribbon 1 is placed on each grid line of the solar cells, the adhesive dots are irradiated by the irradiation unit 6, so that each ribbon 1 is initially fixed to each grid line of the solar cells. Preferably, the irradiation unit 6 is a UV lamp.

[0088] Specifically, in this embodiment, except for the even-numbered solder strips 12 on the outermost side along the extension direction of the solder strip 1, each odd-numbered solder strip 11 and each even-numbered solder strip 12 has three adhesive dots, located at both ends and the middle of each solder strip 1, respectively. For example... Figure 3-4 As shown, the irradiation unit 6 on the first mounting plate 521 irradiates the dispensing dots in the middle of the odd-numbered solder strips 11, and irradiates the two dispensing dots at the ends of two adjacent even-numbered solder strips 12 in the extension direction of the solder strip 1. The irradiation unit 6 on the outermost second mounting plate 531 irradiates the dispensing dots at one end of the outermost odd-numbered solder strips 11 and even-numbered solder strips 12. The irradiation units 6 on the remaining second mounting plates 531 irradiate the dispensing dots in the middle of the even-numbered solder strips 12, and irradiate the two dispensing dots at the ends of two adjacent odd-numbered solder strips 11 in the extension direction of the solder strip 1.

[0089] In a further preferred embodiment, after each of the first pressing part 55, each of the second pressing part 56 and each of the third pressing part 57 presses the corresponding solder ribbon 1 onto the grid line of the battery cell, the irradiation part 6 is activated again, so that each adhesive dot on the battery cell is cured, thereby initially fixing each solder ribbon 1 onto the grid line of the battery cell.

[0090] The gripping component 32 in this embodiment can be designed as follows:

[0091] refer to Figure 5 The clamping assembly 32 also includes an upper mounting plate 322 and a lower mounting plate 323. The gripper unit 321 includes an upper gripping part 3211 and a lower gripping part 3212. All the upper gripping parts 3211 corresponding to each clamping assembly 32 are mounted on the same upper mounting plate 322 in a direction perpendicular to the extension direction of the welding strip 1. All the lower gripping parts 3212 corresponding to each clamping assembly 32 are mounted on the same lower mounting plate 323 in a direction perpendicular to the extension direction of the welding strip 1.

[0092] When clamping the welding strip 1, the first power output component 2 drives the lower mounting plate 323 to move laterally, so that all the lower clamping parts 3212 on the lower mounting plate 323 move simultaneously from the side below the corresponding welding strip 1 to below the welding strip 1, and can drive the upper mounting plate 322 to move downward, so that all the upper clamping parts 3211 on the upper mounting plate 322 move downward simultaneously, until each upper clamping part 3211 presses the welding strip 1 below it onto the lower clamping part 3212 below the welding strip 1;

[0093] When the welding strip 1 is released, the first power output component 2 drives the upper mounting plate 322 to move upward, so that all the upper clamping parts 3211 on the upper mounting plate 322 move upward at the same time, and can drive the lower mounting plate 323 to move laterally, so that all the lower clamping parts 3212 on the lower mounting plate 323 move from below the corresponding welding strip 1 to the side below the welding strip 1 at the same time.

[0094] When the solder strip 1 is released, the upper clamping part 3211 moves upward and separates from the solder strip 1, and the lower clamping part 3212 moves laterally from below the solder strip 1 to the side below the solder strip 1. In this way, the lateral offset of the solder strip 1 can be reduced when placing the solder strip 1, so that the solder strip 1 can be arranged on the battery cell with high accuracy.

[0095] In this embodiment, the upper clamping part 3211 can be a probe or made of other flexible materials, as long as the upper clamping part 3211, in conjunction with the lower clamping part 3212, does not damage the solder ribbon 1 when clamping and placing it. Furthermore, the lower clamping part 3212 has high rigidity, ensuring that when the upper clamping part 3211 presses the solder ribbon 1 onto the lower clamping part 3212, the lower clamping part 3212 will not deform due to the downward pressure of the upper clamping part 3211, thus ensuring that the solder ribbon 1 can be clamped by the upper clamping part 3211 and the lower clamping part 3212. Preferably, the lower clamping part 3212 is relatively thin, so that during the placement of the solder ribbon 1, the height difference between the solder ribbon 1 and the battery cell is small, thereby reducing the degree of deviation of the solder ribbon 1 during its descent. More preferably, the thickness of the lower clamping part 3212 is less than 0.5 mm.

[0096] In this embodiment, the first power output component 2 can be a cylinder. For example, the first power output component 2 includes a horizontal movement cylinder and a vertical movement cylinder. The horizontal movement cylinder drives the lower mounting plate 323 to move horizontally, and the vertical movement cylinder drives the upper mounting plate 322 to move vertically. In this way, one horizontal movement cylinder and one vertical movement cylinder can be provided. One horizontal movement cylinder drives each lower mounting plate 323 in each clamping module 3 to move horizontally simultaneously, and one vertical movement cylinder drives each upper mounting plate 322 in each clamping module 3 to move vertically simultaneously. Alternatively, multiple horizontal movement cylinders and multiple vertical movement cylinders can be provided. Each horizontal movement cylinder drives a portion of the lower mounting plate 323 to move horizontally, and each vertical movement cylinder drives a portion of the upper mounting plate 322 to move vertically. This embodiment does not impose specific limitations on the number of horizontal movement cylinders and vertical movement cylinders or whether each upper mounting plate 322 and each lower mounting plate 323 moves simultaneously.

[0097] In a preferred embodiment, the first power output member 2 can drive the upper clamping part 3211 to move up and down while simultaneously driving the lower clamping part 3212 to move laterally.

[0098] For details, please refer to Figure 5 and Figure 7A cam follower 3221 is mounted on the upper mounting plate 322, and a guide groove 3231 is provided on the lower mounting plate 323. The upper part of the guide groove 3231 is inclined, and the lower part of the guide groove 3231 is vertical.

[0099] When the welding strip 1 is clamped, the first power output component 2 drives the upper mounting plate 322 to move downward, and the cam follower 3221 moves from the upper end to the lower end of the guide groove 3231, so that the lower clamping part 3212 moves from the side below the welding strip 1 to below the welding strip 1. At the same time, the upper clamping part 3211 moves downward until the upper clamping part 3211 presses the welding strip 1 onto the lower clamping part 3212 below the welding strip 1.

[0100] When the welding strip 1 is released, the first power output component 2 drives the upper mounting plate 3211 to move upward, and the cam follower 3221 moves from the lower end of the guide groove 3231 to the upper end, so that the upper clamping part 3211 moves upward, and at the same time the lower clamping part 3212 moves from below the welding strip 1 to the side below the welding strip 1.

[0101] In this embodiment, the first power output component 2 directly drives the upper mounting plate 322 to move up and down, and indirectly drives the lower mounting plate 323 to move laterally.

[0102] When clamping the welding strip 1, the first power output component 2 drives the upper mounting plate 322 to move downward. The cam follower 3221 first moves in the upper part of the guide groove 3231, which is inclined. This causes the lower mounting plate 323 to move laterally while the upper mounting plate 322 moves downward. That is, during the downward movement of the upper clamping part 3211, the lower clamping part 3212 moves from the side below the welding strip 1 to below the welding strip 1. Then, the first power output component 2 continues to drive the upper mounting plate 322 to move downward, causing the cam follower 3221 to enter the lower part of the guide groove 3231, which is vertically set. At this time, the lower mounting plate 323 no longer moves laterally, and the lower clamping part 3212 is always located below the welding strip 1. The first power output component 2 drives the upper mounting plate 322 to move downward until the upper clamping part 3211 presses the welding strip 1 onto the lower clamping part 3212 below it. During this process, the length of the lower part of the guide groove 3231 should be sufficient to allow the upper clamping part 3211 to move downwards and press the welding strip 1 onto the lower clamping part 3212.

[0103] When the welding strip 1 is released, the first power output component 2 drives the upper mounting plate 322 to move upward. The cam follower 3221 first moves in the lower part of the guide groove 3231. At this time, the lower clamping part 3212 is stationary, and the upper clamping part 3211 moves upward. The first power output component 2 continues to drive the upper mounting plate 322 to move upward, so that the cam follower 3221 enters the upper part of the guide groove 3231. At this time, the lower mounting plate 323 moves laterally, and the upper mounting plate 322 continues to move upward. That is, the lower clamping part 3212 moves from below the welding strip 1 to the side below the welding strip 1, and the upper clamping part 3211 continues to move upward, so that the welding strip 1 is detached from the lower clamping part 3212 and placed on the grid line of the battery cell.

[0104] The tilt angle of the upper part of the guide groove 3231 can be set according to the actual needs of the distance the lower clamping part 3212 moves laterally. This angle allows the lower clamping part 3212 to be positioned just below the corresponding welding strip 1 when the cam follower 3221 moves from the upper part of the guide groove 3231 to the lower part.

[0105] In a preferred embodiment, when clamping or releasing the welding strip 1, the upper mounting plate 322 is guided by a vertical guide element, and the lower mounting plate 323 is guided by a horizontal guide element.

[0106] Specifically, the upper mounting plate 322 is movably connected to the base 31 via a vertical guide element, and the lower mounting plate 323 is movably connected to the base 31 via a horizontal guide element.

[0107] Vertical and horizontal guiding elements can be formed by a guide rail and slider, or they can be linear motion components such as guide rods and linear bearings. This embodiment uses a guide rail and slider as an example for further explanation.

[0108] The vertical guide element includes a vertical guide rail and a vertical slider. The vertical guide rail is vertically mounted on the base 31, and the vertical slider is mounted on the upper mounting plate 322, with the vertical slider slidably connected to the vertical guide rail. During the up-and-down movement of the upper mounting plate 322, the vertical slider slides up and down on the vertical guide rail, thereby guiding the up-and-down movement of the upper mounting plate 322, further ensuring the arrangement accuracy of the welding strip 1, and ensuring that each gripper unit 321 can smoothly grip the welding strip 1. Alternatively, the vertical guide rail can be vertically mounted on the upper mounting plate 322, and the vertical slider can be mounted on the base 31, with the vertical slider slidably mounted on the vertical guide rail.

[0109] It is understood that each upper mounting plate 322 is slidably connected to the base 31 via a vertical guide element. Preferably, each upper mounting plate 322 is slidably connected to the base 31 via two vertical guide elements, and vertical directional elements 33 are provided on both sides of the base 31 in a direction perpendicular to the extension direction of the solder strip 1.

[0110] The horizontal guiding element includes a horizontal guide rail and a horizontal slider. The horizontal guide rail is horizontally mounted on the base 31, and the horizontal slider is mounted on the lower mounting plate 323. The horizontal slider is slidably connected to the horizontal guide rail. During the lateral movement of the lower mounting plate 323, the horizontal slider moves laterally on the horizontal guide rail, thereby guiding the movement of the lower mounting plate 323 and ensuring that each gripper unit 321 can smoothly grip the welding strip 1. Alternatively, the horizontal guide rail can be horizontally mounted on the lower mounting plate 323, and the horizontal slider can be mounted on the base 31, slidably mounted on the horizontal guide rail.

[0111] It is understood that each lower mounting plate 323 is slidably connected to the base 31 via a horizontal guide element. Preferably, each lower mounting plate 323 is slidably connected to the base 31 via two horizontal guide elements, and horizontal guide elements are provided on both sides of the base 31 in a direction perpendicular to the extension direction of the welding strip 1.

[0112] In this implementation, the first power output component 2 can also be a cylinder, which drives each upper mounting plate 322 to move up and down, thereby achieving the gripping and releasing of the welding strip 1. For example, only one cylinder is provided, and all the upper mounting plates 322 are mounted on a drive rod. The cylinder drives the drive rod to move up and down, thereby achieving the up and down movement of all the upper mounting plates 322.

[0113] In this embodiment, each base 31 is mounted on the main support 8 via a connector 7. The first power output component 2 and the second power output component 51 are both mounted on the main support 8. The connector 7 and the base 31 are connected by multiple leveling bolts 9, which can be adjusted to adjust the flatness of the base 31. The main support 8 is moved by the drive mechanism, allowing the ribbon arrangement and conveying device of this embodiment to move back and forth between the ribbon preparation station and the ribbon arrangement station.
