[0051] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] like Figures 1 to 4 As shown, the string welding typesetting equipment in the embodiment of the present application includes a first string welding part 1, a second string welding part 2, a first conveying mechanism 3, a second conveying mechanism 4, a first loading and conveying mechanism 5, a second loading and conveying mechanism 6 and a typesetting picking mechanism 7, wherein:

[0053] The first string welding section 1 and the second string welding section 2 are spaced apart. The first string welding section 1 and the second string welding section 2 are both configured to output the welded battery strings along a first horizontal direction (eg, X-axis direction).

[0054] The first loading and conveying mechanism 5 and the second loading and conveying mechanism 6 are arranged side by side and spaced apart along the second horizontal direction (for example, the Y-axis direction) and have opposite conveying directions, wherein the input end of the first loading and conveying mechanism 5 is located behind the output end of the first string welding part 1, the input end of the second loading and conveying mechanism 6 is located behind the output end of the second string welding part 2, the output end of the second loading and conveying mechanism 6 is close to the output end of the first loading and conveying mechanism 5, and the second horizontal direction is perpendicular to the first horizontal direction.

[0055] The first transport mechanism 3 is configured to transport the battery string output from the first string welding unit 1 to the first loading and conveying mechanism 5 . The first loading and conveying mechanism 5 is configured to transport the battery string to the first loading station A along the second horizontal direction.

[0056] The second transport mechanism 4 is configured to transport the battery string output from the second string welding unit 2 to the second loading and conveying mechanism 6 . The second loading and conveying mechanism 6 is configured to transport the battery string to the second loading station B along the second horizontal direction.

[0057] The typesetting picking mechanism 7 is located above the first feeding conveying mechanism 1 and the second feeding conveying mechanism 2. The typesetting picking mechanism 7 is configured to pick up the battery strings from the first feeding station A and the second feeding station B and transport them to the back channel.

[0058] In the string welding typesetting equipment of the embodiment of the present application, the output ends of the first string welding part 1 and the second string welding part 2 are respectively provided with a first loading and conveying mechanism 5 and a second loading and conveying mechanism 6. The first loading and conveying mechanism 5 and the second loading and conveying mechanism 6 respectively convey the battery strings to the first loading station A and the second loading station B near the typesetting picking mechanism 7, so that the typesetting picking mechanism 7 can pick up the battery strings from the first loading station A and the second loading station B nearby, thereby improving the picking speed of the typesetting picking mechanism 7 and ultimately improving the production efficiency of the string welding typesetting equipment. In addition, the typesetting picking mechanism 7 picks up the battery strings from the first loading station A and the second loading station B each time, thereby simplifying the movement control strategy of the typesetting picking mechanism 7.

[0059] Optional, such as Figure 2 and Figure 3 As shown, the first loading and conveying mechanism 5 and the second loading and conveying mechanism 4 have the same structure. Taking the first loading and conveying mechanism 5 as an example, it includes a conveyor belt that conveys battery strings 100 along the second horizontal direction. The width of the conveyor belt along the first horizontal direction is at least equal to the length of one battery string 100, and the conveyor belt can carry at least two battery strings 100 along the second horizontal direction. The first transport mechanism 3 transports the battery strings to the input end of the conveyor belt, and the conveyor belt transports the battery strings along the second horizontal direction to the first loading station A.

[0060] Conveyor belts are used as the first loading and conveying mechanism 5 and the second loading and conveying mechanism 6. The first loading and conveying mechanism 5 and the second loading and conveying mechanism 6 can carry at least two battery strings along the second horizontal direction, thereby realizing the caching of the battery strings and ensuring that the subsequent typesetting picking mechanism 7 can obtain the battery strings from the first loading and conveying mechanism 5 and the second loading and conveying mechanism 6 in time to prevent feeding waiting.

[0061] Of course, the first loading and conveying mechanism 5 and the second loading and conveying mechanism 4 may also adopt other conveying mechanisms, such as a conveying platform driven by a translation drive member.

[0062] like Figure 3 As shown, optionally, the typesetting picking mechanism 7 includes a first picking part 71 and a second picking part 72, wherein the first picking part 71 is configured to pick up at least one battery string from the first loading station A and transport it to the back-end, and the second picking part 72 is configured to pick up at least one battery string from the second loading station B and transport it to the back-end.

[0063] The layout pickup mechanism 7 uses a first pickup portion 71 and a second pickup portion 72 to synchronously pick up battery strings from the first loading station A and the second loading station B and transport them to the downstream process, thereby improving layout efficiency. The first pickup portion 71 and the second pickup portion 72 can, for example, be a suction cup assembly that can absorb and release the battery string.

[0064] Optionally, the string soldering typesetting equipment in the embodiment of the present application further includes a first positioning mechanism and a second positioning mechanism, wherein: the first positioning mechanism is located above the first loading station A, and the first positioning mechanism A is configured to position the battery string located at the first loading station A. The first picking unit 71 picks up the battery string from the first loading station A based on the position information of the battery string at the first loading station A, thereby ensuring the smooth picking of the battery string located at the first loading station. The second positioning mechanism is located above the second loading station B, and the second positioning mechanism is configured to position the battery string at the second loading station B. The second picking unit picks up the battery string from the second loading station B based on the position information of the battery string at the second loading station B, thereby ensuring the smooth picking of the battery string located at the second loading station.

[0065] Both the first positioning mechanism and the second positioning mechanism can adopt visual positioning mechanism. Taking the first positioning mechanism as an example, Figure 2 As shown, it includes two cameras, which respectively take pictures and locate the two ends of the battery string located at the first loading station A, thereby obtaining the position information of the battery string located at the first loading station A.

[0066] like Figure 1As shown, optionally, the first string welding section 1 includes two first string welding conveyor lines 11, which implement dual-line production and dual-line output of battery strings. Correspondingly, the first conveying mechanism 3 includes two first conveying assemblies 31. The first conveying mechanism 3 synchronously picks up two battery strings from the output ends of the two first string welding conveyor lines 11 of the first string welding section 1 through the two first conveying assemblies 31, and conveys the picked up two battery strings to the first loading conveyor mechanism 5. Similarly, the first string welding section 2 includes two second string welding conveyor lines 21, which implement dual-line production and dual-line output of battery strings. Correspondingly, the second conveying mechanism 4 includes two second conveying assemblies 41. The second conveying mechanism 4 synchronously picks up two battery strings from the output ends of the two second string welding conveyor lines 21 of the second string welding section 2 through the two second conveying assemblies, and conveys the picked up two battery strings to the second loading conveyor mechanism 6.

[0067] The first string welding section 1 and the first string welding section 2 implement dual-line production and dual-line output of battery strings. The first conveying mechanism 3 and the second conveying mechanism 4 convey two battery strings to the first loading and conveying mechanism 5 and the second loading and conveying mechanism 6 respectively each time, which can further ensure that the subsequent typesetting picking mechanism 7 can obtain the battery strings from the first loading and conveying mechanism 5 and the second loading and conveying mechanism 6 in time, thereby improving typesetting efficiency.

[0068] Of course, in order to reduce equipment costs, the first string welding section 1 may also include only one first string welding conveyor line 11, and correspondingly, the first conveying mechanism 3 may include only one first conveying assembly 31. The first conveying mechanism 3 picks up one battery string from the first string welding section 1 each time and conveys the picked battery string to the first loading conveyor mechanism 5. Similarly, the second string welding section 2 may also include only one second string welding conveyor line 21, and correspondingly, the second conveying mechanism 4 may include only one second conveying assembly 41. The second conveying mechanism 4 picks up one battery string from the second string welding section 2 each time and conveys the picked battery string to the second loading conveyor mechanism 6.

[0069] The first transport assembly 31 and the second transport assembly 41 may be, for example, suction cup assemblies capable of sucking and releasing battery strings.

[0070] Continue to refer Figures 1 to 4 As shown, the string welding layout equipment optionally further includes a regular conveying mechanism 8, a welding pickup mechanism 9, and a welding mechanism 10. The layout pickup mechanism 7 is configured to place at least two battery strings picked up from the first loading station A and the second loading station B onto the regular conveying mechanism 8 according to the layout positive and negative polarity requirements each time to obtain at least one assembly unit. Each assembly unit includes two battery strings arranged in parallel along the length direction of the battery string, and multiple assembly units are arranged in parallel along the width direction of the battery string to form a battery string array.

[0071] The regular conveying mechanism 8 is configured to carry and regularize at least one component unit, and the number of component units carried by the regular conveying mechanism 8 is less than the number of component units included in the battery string array. Figure 1 and Figure 3 As shown, the arranging and conveying mechanism 8 is capable of carrying and arranging two component units.

[0072] The welding pickup mechanism 9 includes a string picking assembly 91 arranged in a one-to-one correspondence with each component unit in the battery string array. The regular conveying mechanism 8 is also configured to transport all the component units it carries to the string picking station according to the layout position requirements, and after all the component units it carries have been removed, return to receive the component units placed by the layout pickup mechanism 7. The welding pickup mechanism 9 moves to drive the string picking assembly corresponding to the component unit at the string picking station to move to the string picking station to pick up the component unit, and then drives the string picking assembly with the picked component unit to the welding station.

[0073] The welding mechanism 10 is located at the welding station and is used to weld busbars to the extended welding strips of at least one module unit located at the welding station. The welding pickup mechanism 10 is also used to move and place the cell strings picked up by each string picking assembly on the glass plate after the busbars of the cell strings have been welded.

[0074] In order to enable those skilled in the art to more clearly understand the working process of this application, the following Figures 1 to 4 and Figure 7 A detailed and exemplary introduction is given to the layout and busbar welding process of the string welding layout equipment in the embodiment of the present application.

[0075] like Figure 7 As shown, the battery string array to be prepared in the embodiment of the present application includes six component units, namely, a first component unit PA1-PB1 consisting of battery string PA1 and battery string PB1, a second component unit PA2-PB2 consisting of battery string PA2 and battery string PB2, a third component unit PA3-PB3 consisting of battery string PA3 and battery string PB3, a fourth component unit PA4-PB4 consisting of battery string PA4 and battery string PB4, a fifth component unit PA5-PB5 consisting of battery string PA5 and battery string PB5, and a sixth component unit PA6-PB6 consisting of battery string PA6 and battery string PB6. The two battery strings in each component unit are arranged side by side along the second horizontal direction (such as the Y-axis direction), and the six component units are arranged side by side along the first horizontal direction (such as the X-axis direction) to form 6 groups of 12 battery string groups.

[0076] There are four intermediate busbars in the middle of the battery string group that need to be bent, namely busbar M1, busbar M2, busbar M3 and busbar M4, among which: busbar M1 is used to weld battery string PA1 and battery string PB1, busbar M2 is used to weld battery string PA2 and battery string PB2, battery string PA3 and battery string PB3, busbar M3 is used to weld battery string PA4 and battery string PB4, battery string PA5 and battery string PB5, and busbar M4 is used to weld battery string PA6 and battery string PB6.

[0077] The head end of each battery string group requires welding three straight head busbars, namely: welding busbar A1 at the head end of battery strings PA1 and PA2, welding busbar A2 at the head end of battery strings PA3 and PA4, and welding busbar A3 at the head end of battery strings PA5 and PA6. The tail end of each battery string group requires welding three straight tail busbars, namely: welding busbar B1 at the tail end of battery strings PB1 and PB2, welding busbar B2 at the tail end of battery strings PB3 and PB4, and welding busbar B3 at the tail end of battery strings PB5 and PB6.

[0078] For the above-mentioned battery string group, the optional tooling process of the layout and busbar welding of the string welding layout equipment in the embodiment of the present application is as follows:

[0079] The typesetting picking mechanism 7 picks up the battery strings PA1 and PA2 from the first loading station A, and rotates the battery strings PA1 and PA2 so that the length directions of the battery strings PA1 and PA2 are parallel to the second horizontal direction (such as the Y-axis direction). At the same time, the typesetting picking mechanism 7 picks up the battery strings PB1 and PB2 from the second loading station B, and rotates the battery strings PB1 and PB2 so that the length directions of the battery strings PB1 and PB2 are parallel to the second horizontal direction (such as the Y-axis direction). Subsequently, the typesetting picking mechanism 7 places the rotated battery strings PA1 and PA2 and the rotated battery strings PB1 and PB2 on the regular conveying mechanism 8, thereby obtaining the first component unit PA1-PB1 and the second component unit PA2-PB2.

[0080] It should be noted here that, depending on the number of suction cup assemblies provided by the typesetting and picking mechanism 7, the typesetting and picking mechanism 7 can simultaneously implement the picking and rotation of the battery string PA1 and the battery string PA2, or it can separately implement the picking and rotation of the battery string PA1 and the battery string PA2 in two batches. Similarly, the typesetting and picking mechanism 7 can simultaneously implement the picking and rotation of the battery string PB1 and the battery string PB2, or it can separately implement the picking and rotation of the battery string PB1 and the battery string PB2 in two batches. The picking and rotation of other battery strings described below are the same and will not be repeated. In addition, the regularizing and conveying mechanism 8 needs to be able to carry and regularize two component units at the same time.

[0081] Subsequently, the straightening and conveying mechanism 8 completes the straightening of the first and second assembly units PA1-PB1 and PA2-PB2, and conveys them to the string picking station. The welding pick-up mechanism 9 drives the first and second string picking groups to the string picking station to pick up the first and second assembly units PA1-PB1 and PA2-PB2, and then conveys them to the welding station. At the same time, the straightening and conveying mechanism 8 returns to its original position.

[0082] The welding mechanism 10 welds the busbar A1 to the head ends of the battery strings PA1 and PA2 , welds the busbar B1 to the tail ends of the battery strings PB1 and PB2 , and welds the busbar M1 between the battery strings PA1 and PB1 .

[0083] Next, the typesetting picking mechanism 7 picks up the battery strings PA3 and PA4 from the first loading station A, and rotates the battery strings PA3 and PA4 so that the length directions of the battery strings PA3 and PA4 are parallel to the second horizontal direction (such as the Y-axis direction). At the same time, the typesetting picking mechanism 7 picks up the battery strings PB3 and PB4 from the second loading station B, and rotates the battery strings PB3 and PB4 so that the length directions of the battery strings PB3 and PB4 are parallel to the second horizontal direction (such as the Y-axis direction). Subsequently, the typesetting picking mechanism 7 places the rotated battery strings PA3 and PA4, the rotated battery strings PB3 and PB4 on the regular conveying mechanism 8, thereby obtaining the third component unit PA3-PB3 and the fourth component unit PA4-PB4.

[0084] Subsequently, the alignment and conveying mechanism 8 completes the alignment of the third and fourth assembly units PA3-PB3 and PA4-PB4, and conveys them to the string picking station. The welding pickup mechanism 9 drives the third and fourth string picking groups to move to the string picking station to pick up the third and fourth assembly units PA3-PB3 and PA4-PB4, and conveys them to the welding station. At the same time, the alignment and conveying mechanism 8 moves back to its original position.

[0085] The welding mechanism 10 welds the busbar A2 to the head ends of the battery strings PA3 and PA4, welds the busbar B2 to the tail ends of the battery strings PB3 and PB4, and welds the busbar M2 between the battery strings PA2, PB2, PA3, and PB3.

[0086] Next, the typesetting picking mechanism 7 picks up the battery strings PA5 and PA6 from the first loading station A, and rotates the battery strings PA5 and PA6 so that the length directions of the battery strings PA5 and PA6 are parallel to the second horizontal direction (such as the Y-axis direction). At the same time, the typesetting picking mechanism 7 picks up the battery strings PB5 and PB6 from the second loading station B, and rotates the battery strings PB5 and PB6 so that the length directions of the battery strings PB5 and PB6 are parallel to the second horizontal direction (such as the Y-axis direction). Subsequently, the typesetting picking mechanism 7 places the rotated battery strings PA5 and PA6, the rotated battery strings PB5 and PB6 on the regular conveying mechanism 8, thereby obtaining the fifth component unit PA5-PB5 and the sixth component unit PA6-PB6.

[0087] Subsequently, the straightening and conveying mechanism 8 completes the straightening of the fifth and sixth component units PA5-PB5 and PA6-PB6, and conveys them to the string picking station. The welding pickup mechanism 9 drives the fifth and sixth string picking groups to the string picking station to pick up the fifth and sixth component units PA5-PB5 and PA6-PB6, and then conveys them to the welding station. At the same time, the straightening and conveying mechanism 8 moves back to its initial position.

[0088] Welding mechanism 10 welds busbar A3 to the leading ends of battery strings PA5 and PA6, busbar B3 to the trailing ends of battery strings PB5 and PB6, busbar M3 to battery strings PA4, PB4, and between battery strings PA5 and PB5, and busbar M4 to between battery strings PA6 and PB6. The final battery string assembly is now completed, and welding pick-up mechanism 9 places the assembly on a glass plate.

[0089] like Figures 3 and 4 As shown, optionally, the regularizing and conveying mechanism 8 includes a first regularizing component 81 and a second regularizing component 82, and the first regularizing component 81 and the second regularizing component 82 are arranged at intervals along the second horizontal direction, wherein the first regularizing component 81 is used to carry and regularize one of the battery strings in each component unit, and the second regularizing component 82 is used to carry and regularize the other battery string in each component unit. For example, for the first component unit PA1-PB1 mentioned above, the first regularizing component 81 is used to carry and regularize the battery string PA1 therein, and the second regularizing component 82 is used to carry and regularize the battery string PB1 therein. For the second component unit PA2-PB2 mentioned above, the first regularizing component 81 is used to carry and regularize the battery string PA2 therein, and the second regularizing component 82 is used to carry and regularize the battery string PB2 therein.

[0090] Optionally, the first aligning assembly 81 includes a first translation drive unit 811 and at least one first aligning platform 812 connected to the mobile end of the first translation drive unit 811, wherein the first aligning platform 812 is used to carry and align a string of batteries in the assembly unit. The first translation drive mechanism 811 is used to drive each first aligning platform 12 to translate along a first horizontal direction to transport the aligned battery strings to the string picking station.

[0091] Similarly, the second aligning assembly 82 includes a second translation drive unit 821 and at least one second aligning platform 822 connected to the movable end of the second translation drive unit 821, corresponding one-to-one with the first aligning platform 812. The second aligning platform 822 is used to carry and align another battery string in the assembly unit. The second translation drive mechanism 821 is used to drive each second aligning platform 822 to translate along the first horizontal direction to transport the aligned battery string to the string picking station.

[0092] Figures 3 and 4In the illustrated embodiment, the first arranging assembly 81 includes two first arranging platforms 812, and correspondingly, the second arranging assembly 82 also includes two second arranging platforms 822. Therefore, the first arranging assembly 81 and the second arranging assembly 82 can simultaneously implement the carrying and arranging of two component units, and transport the two arranged component units to the picking station. For example, as described above, the carrying and arranging of the first component unit PA1-PB1 and the second component unit PA2-PB2 are simultaneously implemented, and the arranged first component unit PA1-PB1 and the second component unit PA2-PB2 are transported to the picking station.

[0093] Of course, the first organizing assembly 81 may also include one, three, or other numbers of first organizing platforms 812, and the second organizing assembly 82 may include a corresponding number of second organizing platforms 822. This allows the first organizing assembly 81 and the second organizing assembly 82 to cooperate in carrying and organizing one, three, or other numbers of component units, and to transport all organized component units to the string picking station.

[0094] Both the first translation driving unit 811 and the second translation driving unit 821 may adopt existing linear driving modules of various structures, such as a screw driving module, a cylinder driving module, etc.

[0095] Optionally, the first regularization platform 812 and the second regularization platform 822 have the same structure. Figure 5 As shown, taking the first aligning platform 812 as an example, it includes a third translation drive unit 8121, a lifting drive unit 8122, a rotation drive unit 8123, and an aligning carrier plate 8124. The third translation drive unit 8121 is connected to the driving end of the first translation drive unit 811, the lifting drive unit 8122 is connected to the driving end of the third translation drive unit 8121, the rotation drive unit 8123 is connected to the driving end of the lifting drive unit 8122, and the aligning carrier plate 8124 is connected to the driving end of the rotation drive unit 8123. The aligning carrier plate 8124 is used to carry the battery string. The third translation drive unit 8121 is used to drive the aligning carrier plate 8124 to translate along the second horizontal direction, the lifting drive unit 8122 is used to drive the aligning carrier plate 8124 to move up and down, and the rotation drive unit 8123 is used to drive the aligning carrier plate 8124 to rotate within the horizontal plane.

[0096] Through the cooperation of the first translation drive unit 811, the third translation drive unit 8121 and the rotation drive unit 8123, the regularization carrier plate 8124 can be driven to achieve translation in the first horizontal direction and the second horizontal direction and rotation in the horizontal plane, thereby regularizing the position of the battery strings placed on the regularization carrier plate 8124 and delivering the regularized battery strings to the picking station according to the layout position requirements. The lifting drive unit 8122 can drive the regularization carrier plate 8124 to rise after it moves to the picking station to transfer the battery strings to the corresponding picking assembly 91 on the welding picking mechanism 9.

[0097] Optionally, the welding pickup mechanism 9 further includes a stepper drive assembly and a mounting bracket, wherein the mounting bracket is connected to the movable end of the stepper drive assembly, and each of the pick-up assembly 91 is mounted on the mounting bracket. The stepper drive assembly is configured to stepper drive each of the pick-up assembly 91 to translate, so as to drive the pick-up assembly 91 corresponding to the component unit at the pick-up station to the pick-up station to pick up the component unit, and at the same time drive the pick-up assembly 91 that has picked up the component unit to the welding station.

[0098] It can be seen that the stepping of each picking string component 91 is implemented through the stepping drive component, so that each picking string component 91 can step the component units transported by the regular conveying mechanism 8 from the picking string station to the welding station in sequence, until multiple component units with bus bars are welded to form a battery string array.

[0099] For example, the regular conveying mechanism 8 can synchronously carry and regularize two component units, and it delivers two component units to the picking-up station at a time, and correspondingly, the stepping drive assembly drives two picking-up components 91 stepwise to the picking-up station at a time, so that the two picking-up components 91 can simultaneously pick up two component units from the picking-up station. Subsequently, the stepping drive assembly continues to drive each picking-up component 91 to step, so that the two picking-up components 91 that pick up component units move to the welding station. For another example, the regular conveying mechanism 8 can only carry and regularize one component unit, so it only delivers one component unit to the picking-up station at a time, and correspondingly, the stepping drive assembly drives one picking-up component 91 stepwise to the picking-up station at a time, so that the picking-up component 91 picks up one component unit from the picking-up station. Subsequently, the stepping drive assembly continues to drive each picking-up component 91 to step, so that the picking-up component 91 that picks up component units moves to the welding station.

[0100] Continue to refer Figure 1As shown, the welding mechanism 10 optionally includes a busbar preparation assembly, a busbar handling assembly, a busbar supporting assembly, and a welding assembly, wherein: the busbar preparation assembly is configured to prepare the busbar. The busbar handling assembly is configured to transport the busbar to the busbar supporting assembly.

The welding assembly is used to weld the busbar carried by the busbar supporting portion to the extended weld strip.

[0101] The busbar preparation assembly is used to prepare the busbar, the busbar is transported from the busbar preparation assembly to the busbar carrying assembly is used to transport the busbar, the busbar carrying movement and welding support are achieved through the setting of the busbar carrying assembly, and the busbar is welded to the long welding strip through the welding assembly. When the busbar carrying assembly and the welding assembly cooperate to weld the busbar, the busbar preparation assembly and the busbar transport assembly can simultaneously prepare and transport the busbar, thereby improving efficiency.

[0102] Of course, the number of busbars prepared by the busbar preparation assembly, the number of busbars handled by the busbar handling assembly, the number of busbars carried by the busbar support assembly, and the number of busbars welded by the welding assembly are all set accordingly based on the number of component units currently to be welded. Because the busbars are welded to the battery strings in batches, the number of busbar preparation assemblies, busbar handling assemblies, busbar support assemblies, and welding assemblies can be reduced, reducing equipment costs.

[0103] like Figure 6 As shown, optionally, the busbar preparation assembly includes a leading busbar preparation unit 101, and intermediate and trailing busbar preparation units 102. The busbar handling assembly includes a first handling unit and a second handling unit. The busbar supporting assembly includes a leading busbar support platform 103, a trailing busbar support platform 104, and an intermediate busbar support platform 105. The welding assembly includes a leading welding unit 106, an intermediate welding unit 107, and a trailing welding unit 108.

[0104] The head bus bar preparation section 101 is used to prepare the head bus bar (for example, the bus bar A1, bus bar A2 and bus bar A3 mentioned above), the first conveying section is used to convey the head bus bar prepared by the head bus bar preparation section to the head bus bar carrier 103, the head bus bar carrier 103 is used to move the head bus bar to the bottom of the extended welding strip at the head of the component unit, and the head welding section 106 is used to weld the head bus bar to the extended welding strip at the head of the component unit.

[0105] The middle and tail bus bar preparation section 102 is used to prepare middle bus bars (such as the bus bar M1, bus bar M2, bus bar M3 and bus bar M4 mentioned above) and tail bus bars (such as the bus bar B1, bus bar B2 and bus bar B3 mentioned above). The second conveying mechanism is used to convey the middle bus bars and tail bus bars prepared by the middle and tail bus bar preparation sections to the middle bus bar carrier 105 and the tail bus bar carrier 104 respectively. The middle bus bar carrier 105 moves the middle bus bar to the bottom of the extended weld strip in the middle of the component unit. The middle welding section 107 is used to weld the middle bus bar to the extended weld strip in the middle of the component unit. The tail bus bar carrier 104 moves the tail bus bar to the bottom of the extended weld strip at the tail of the component unit. The tail welding section 108 is used to weld the tail bus bar to the extended weld strip at the tail of the component unit.
