Description

Technical Field

[0001] This application belongs to the field of battery processing technology, and particularly relates to a printing system, a method for preparing photovoltaic modules, a photovoltaic module and a string welding machine. Background Technology

[0002] In related technologies, BC string bonding typically employs a method of applying adhesive first and then placing the solder ribbon for curing or a coating method in the lamination process. In the method of applying adhesive first and then placing the solder ribbon, since the adhesive dots are located between the solder ribbon and the cell, the adhesive dots themselves have a certain thickness, which affects the contact area between the solder ribbon and the grid lines, resulting in a reduction in current extraction efficiency. If the adhesive dots are usually placed at both ends of the solder ribbon, yield problems such as cold solder joints and bubbles are likely to occur in the subsequent lamination process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0086] First, it should be noted that the X, Y, and Z directions in the embodiments of this application are referenced in the appendix. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 14 , Figure 17 and Figure 22The marked directions; wherein the axes in the X direction, Y direction, and Z direction intersect each other.

[0087] like Figures 1-22 As shown, according to a first aspect of the embodiments of this application, a printing system 1000 is provided, including a feeding device 300, a printing device 100, and a discharging device 400; the carrying device 200 includes a movable carrying mechanism 201, and a feeding station A, a printing station B, and a discharging station D are sequentially arranged along the moving path of the carrying mechanism 201; the feeding device 300 includes a movable feeding mechanism 302, and the feeding station A and the first buffer area 700 are located on the moving path of the feeding mechanism 302; the printing device 100 is located at the printing station B; and the discharging device 400 is located at the discharging station D.

[0088] like Figures 1-4 As shown, the printing system 1000 includes a first buffer area 700, a carrier device 200, a feeding device 300, a printing device 100, and a unloading device 400. The first buffer area 700 holds solder ribbon 2002. It can be an area for placing solder ribbon 2002, or a solder ribbon 2002 slitting device can be installed in the first buffer area 700, and the feeding device 300 can directly move the solder ribbon 2002 slitting by the solder ribbon 2002 slitting device to the feeding station A.

[0089] To further explain, the carrying device 200 includes a movable carrying mechanism 201, which can move along the X direction. The movement path of the carrying mechanism 201 along the X direction is the first path. Along the first path, there are sequentially arranged loading station A, printing station B, and unloading station D. That is to say, the carrying mechanism 201 can pass through loading station A, printing station B, and unloading station D. The printing device 100 is located at printing station B. More specifically, the printing device 100 is located above printing station B in the Z direction. The unloading device 400 is located at unloading station D.

[0090] To further explain, the feeding device 300 includes a movable feeding mechanism 302. The moving path of the feeding mechanism 302 is a second path. The feeding station A and the first buffer area 700 are both located on the second path. In other words, the feeding mechanism 302 can move to the feeding station A and the first buffer area 700.

[0091] To further explain, the carrier mechanism 201 moves to the loading station A, at which time the battery cell 2001 is placed on the carrier mechanism 201; the loading mechanism 302 moves the solder ribbon 2002 located in the first buffer area 700 to the loading station A and places it on the battery cell 2001. At this time, the carrier mechanism 201 has the battery cell 2001 and the solder ribbon 2002 placed on the battery cell 2001. The carrier mechanism 201 moves along the X direction and moves from the loading station A to the printing station B. The printing device 100 prints adhesive on the solder ribbon 2002 and the battery cell 2001 to fix the solder ribbon 2002 on the battery cell 2001.

[0092] The adhesive printing system 1000 of this application can first place the solder ribbon 2002 on the solar cell 2001, and then print adhesive on the solder ribbon 2002 and the solar cell 2001 through the printing device 100 to fix the solder ribbon 2002 on the solar cell 2001. Therefore, it will not affect the arrangement position of the adhesive dots. That is to say, multiple adhesive dots can be set in the length direction of the solder ribbon 2002, which can avoid yield problems such as poor soldering and bubbles in the subsequent lamination process. Furthermore, the solder ribbon 2002 is in direct contact with the solar cell 2001, which will not affect the contact area between the solder ribbon 2002 and the grid line. Therefore, it can improve the current conduction efficiency, thereby improving the quality of the photovoltaic module 2000.

[0093] like Figure 4 As shown, in an optional embodiment, the first buffer area 700 is provided with a solder ribbon 2002, the carrier mechanism 201 is located at the loading station A, the carrier mechanism 201 is provided with a battery cell 2001, and the loading mechanism 302 moves the solder ribbon 2002 located in the first buffer area 700 to the battery cell 2001 of the carrier mechanism 201 located at the loading station A.

[0094] like Figure 4 As shown, in an optional embodiment, the printing system 1000 further includes a second buffer area 800, which is located on the movement path of the feeding mechanism 302. Specifically, the second buffer area 800 is used to place the pressure screen 3000. The second buffer area 800 is located on the movement path of the feeding mechanism 302, that is, the feeding mechanism 302 can also move to the second buffer area 800 to move the pressure screen 3000 located in the second buffer area 800 to the feeding station A. The pressure screen 3000 will press on the solder ribbon 2002 to prevent the solder ribbon 2002 from shifting.

[0095] In one specific embodiment, the first buffer area 700 and the second buffer area 800 are spaced apart along the X direction, and the first buffer area 700 and the second buffer area 800 are located on the same side of the carrying mechanism 201 in the Y direction; in this embodiment, the feeding mechanism 302 is capable of moving along the X and Y directions.

[0096] like Figure 4 As shown, in another specific embodiment, the first buffer area 700 and the second buffer area 800 are spaced apart along the Y direction, and the first buffer area 700 and the second buffer area 800 are located on both sides of the bearing mechanism 201 in the Y direction; in this embodiment, the feeding mechanism 302 can move along the Y direction; furthermore, in order to facilitate the gripping and placement of the welding strip 2002 / pressing mesh 3000, the feeding mechanism 302 can also move along the X direction.

[0097] After the solar cell 2001 and the welding ribbon 2002 are fixed by the printing device 100 with glue, the screen 3000 is still on the solar cell 2001, and the conveying device 600 is used to remove the screen 3000.

[0098] Specifically, the carrier mechanism 201 can move from the printing station B to the curing station C, that is, move the battery cell 2001 and the solder ribbon 2002, which are fixed by the adhesive dispensing of the printing device 100, to the curing station C; the adhesive printing system 1000 also includes a curing device 500, which is located at the curing station C. The curing device 500 is used to cure the adhesive on the battery cell 2001 and the solder ribbon 2002 that have moved to the curing station C, so that the solder ribbon 2002 can be completely attached to the battery cell 2001 and the connection stability between the solder ribbon 2002 and the battery cell 2001 can be improved.

[0099] To further explain, the conveying device 600 is located between the curing device 500 and the unloading device 400. Before the adhesive on the battery cell 2001 and the welding ribbon 2002 is cured, the welding ribbon 2002 is pressed tightly by the pressure mesh 3000, and then the adhesive is cured to prevent the welding ribbon 2002 and the battery cell 2001 from not being able to fully adhere. After the curing is completed, the conveying device 600 removes the pressure mesh 3000.

[0100] like Figures 1-4As shown, in an optional embodiment, the feeding device 400 includes a first feeding mechanism 401 and a second feeding mechanism 402, with the first feeding mechanism 401 and the second feeding mechanism 402 spaced apart. Specifically, the first feeding mechanism 401 and the second feeding mechanism 402 can be located on opposite sides of the supporting mechanism 201 along the Y direction, or the first feeding mechanism 401 and the second feeding mechanism 402 can be spaced apart along the X direction, with the first feeding mechanism 401 and the second feeding mechanism 402 located on the same side of the supporting mechanism 201. The cured battery cell 2001 and the welding ribbon 2002 constitute a photovoltaic module 2000. The supporting mechanism 201 moves from the curing station to the feeding station D, and the first feeding mechanism 401 and the second feeding mechanism 402 feed alternately to improve feeding efficiency.

[0101] In an optional embodiment, the supporting device 200 further includes a first driving mechanism 301, a driving wheel, and a driven wheel. The output end of the first driving mechanism 301 is connected to the driving wheel, and the driving wheel and the driven wheel are spaced apart. Specifically, the driving wheel and the driven wheel are spaced apart along the X direction, the axis of the driving wheel is parallel to the axis in the Y direction, the axis of the driven wheel is parallel to the axis in the Y direction, the driving end of the first driving mechanism 301 is connected to the driving wheel, and the first driving mechanism 301 can drive the driving wheel to rotate around its own axis.

[0102] Further explanation: The carrying mechanism 201 includes a conveyor belt, which is sleeved on the driving wheel and the driven wheel; when the first driving mechanism 301 drives the driving wheel to rotate, it can drive the conveyor belt to move, and the conveyor belt can move along the X direction; the loading station A, printing station B, curing station C and unloading station D are arranged sequentially along the X direction, and the conveyor belt can be located at the loading station A, printing station B, curing station C and unloading station D at the same time. Therefore, multiple battery cells 2001 can be placed on the conveyor belt, so that the loading device 300, printing device 100, curing device 500 and unloading device 400 can all work at the same time, thereby improving the working efficiency of the printing system 1000 and increasing the production capacity of the printing system 1000.

[0103] In another alternative embodiment, the carrier mechanism 201 includes a transfer platform and a first drive mechanism 301. The transfer platform is connected to the drive end of the first drive mechanism 301, and the first drive mechanism 301 can drive the transfer platform to move in the X direction. The transfer platform is used to place the battery cell 2001 and the welding strip 2002.

[0104] like Figure 1 and Figure 2As shown, in an optional embodiment, the printing apparatus 100 includes a printing mechanism 1 and a second driving mechanism 2, wherein the printing mechanism 1 is connected to the driving end of the second driving mechanism 2; specifically, the second driving mechanism 2 can drive the printing mechanism 1 to move along the Y direction and / or X direction, so that the printing mechanism 1 can move relative to the screen assembly 32.

[0105] like Figure 1 and Figure 2 In one optional embodiment, the printing apparatus 100 further includes a screen printing mechanism 3, which includes a first driving component 31 and a screen printing component 32. The screen printing component 32 is connected to the driving end of the first driving component 31. The screen printing component 32 is closer to the carrier device 200 than the printing mechanism 1. Specifically, the first driving component 31 can drive the screen printing component 32 to move along the Z direction. When the carrier device 201 is located at printing station B, the first driving component 31 can drive the screen printing component 32 to move closer to the carrier device 201 along the Z direction. After the printing mechanism 1 finishes printing, the first driving component 31 can drive the screen printing component 32 to move away from the carrier device 201 along the Z direction, so that the carrier device 201 can move from printing station B to curing station C.

[0106] like Figure 7 , Figure 8 and Figure 9 As shown, in an optional embodiment, the printing mechanism 1 includes a dispensing assembly 11 and a printing head 12. The printing head 12 includes a first squeegee assembly 13 and a second squeegee assembly 14, which are spaced apart. The dispensing assembly 11 is located between the first squeegee assembly 13 and the second squeegee assembly 14. Specifically, the dispensing assembly 11 is used to inject glue into the screen assembly 32. The first squeegee assembly 13 is used to squeeze the glue onto the battery cell 2001 and the solder ribbon 2002 to form glue dots on the battery cell 2001 to fix the solder ribbon 2002. The second squeegee assembly 14 is used to spread the squeezed glue evenly again on the screen assembly 32 to prepare for the next printing.

[0107] like Figure 7 and Figure 9 As shown, the dispensing assembly 11 includes a plurality of dispensing sections 111, which are spaced apart, and each dispensing section 111 is arranged opposite to a corresponding squeegee 133. Specifically, since the screen assembly 32 has a plurality of printing sections 322, each dispensing section 111 injects glue into the corresponding printing section 322, and the corresponding squeegee 133 squeezes the glue at the corresponding printing section 322 onto the solder ribbon 2002.

[0108] like Figure 7 and Figure 9As shown, the dispensing assembly 11 is mounted on the mounting bracket 16; the mounting bracket 16 provides mounting support for the print head 12 and the dispensing assembly 11, and enables the printing mechanism 1 to be modularized for easy installation, replacement and maintenance.

[0109] The first scraper assembly and the second scraper assembly have the same structure. The first scraper assembly will be used as an example for explanation.

[0110] like Figures 7-9 As shown, the first scraper assembly 13 includes a drive component 15 and two scraper modules 132, which are arranged adjacent to each other. Specifically, the two scraper modules 132 are arranged adjacent to each other along the X direction, and both scraper modules 132 are connected to the drive end of the drive component 15. The drive component 15 can simultaneously drive the two scraper modules 132 to move along the Z direction. The two scraper modules 132 have the same structure. In this embodiment, setting two scraper modules 132 can avoid the problem of poor stability caused by setting too many scraper parts 133 in the X direction of the scraper module 132.

[0111] like Figures 7-9 As shown, in an optional embodiment, the scraper module 132 includes a first driving member 136, a third mounting member 137, and a plurality of scraper members 133. The first driving member 136 is disposed at the driving end of the driving component 15, the third mounting member 137 is disposed at the driving end of the first driving member 136, and the plurality of scraper members 133 are spaced apart on the third mounting member 137 along the X direction. The third mounting member 137 is disposed at the driving end of the first driving member 136, and the first driving member 136 can drive the third mounting member 137 and the plurality of scraper members 133 to move along the Z direction. In this embodiment, the driving component 15 performs coarse adjustment of the position of the scraper module 132, and the first driving member 136 performs fine adjustment of the position of the scraper members 133 to improve its position adjustment accuracy. Furthermore, in an embodiment including two scraper modules 132, the plurality of scraper members 133 of each scraper module 132 can be adjusted individually.

[0112] like Figures 10-13As shown, in one optional embodiment, the scraper component 133 includes a sleeve 1331, a third mounting portion 1332, a first scraper 131, a guide rod 134, and a third elastic member 135; the sleeve 1331 is disposed on the third mounting component 137; the third mounting portion 1332 is spaced apart from the sleeve 1331; the first scraper 131 is disposed on the third mounting portion 1332; one end of the guide rod 134 is connected to the third mounting portion 1332, and the other end of the guide rod 134 is connected to the sleeve 1331. A sliding connection is used, with a third elastic element 135 disposed between the sleeve 1331 and the third mounting part 1332, and the third elastic element 135 sleeved on the guide rod 134; specifically, the sleeve 1331 has a third through hole, the axis of the third through hole being parallel to the axis in the Z direction (this parallelism is basically parallel, but may have a certain error), the sleeve 1331 is disposed on the third mounting part 137, and the third mounting part 1332 is arranged at intervals with the sleeve 1331 along the Z direction. Located below the sleeve 1331 in the Z direction, the first scraper 131 is mounted on the third mounting portion 1332, with the first scraper 131 positioned at the end of the third mounting portion 1332 away from the sleeve 1331. One end of the guide rod 134 is fixedly connected to the third mounting portion 1332, and the other end of the guide rod 134 passes through the third through hole. The guide rod 134 is slidably connected to the sleeve 1331. A third elastic element 135 is disposed between the third mounting portion 1332 and the sleeve 1331, and is sleeved on the guide rod 134. In this embodiment, when the first scraper 131 moves downward in the Z direction, it contacts the printing portion 322, compressing the third elastic element 135 and thus buffering the first scraper 131 to avoid damage from rigid contact. The guide rod 134 connects the third mounting portion 1332 and the sleeve 1331 to improve the stability of the first scraper 131 during operation.

[0113] In one alternative embodiment, the first squeegee 131 is arranged at an angle; specifically, the first squeegee 131 is inclined in the direction of movement of the printing mechanism 1, that is, in the Y direction; when the printing mechanism 1 is working, the first squeegee 131 will contact the bottom surface of the printing part 322. When the printing mechanism 1 moves in the Y direction, the side of the first squeegee 131 facing the direction of movement of the printing mechanism 1 forms an angle with the bottom surface of the printing part 322, and the angle is an acute angle; in this embodiment, the first squeegee 131 is inclined in the direction of movement of the printing mechanism 1, which can avoid the problem of the first squeegee 131 chipping.

[0114] like Figure 12 and Figure 13As shown, in an optional embodiment, the third mounting part 1332 includes a first mounting block 13321 and a second mounting block 13322 disposed adjacent to each other. The surface of the first mounting block 13321 facing the second mounting block 13322 is a first inclined surface a, and the surface of the second mounting block 13322 facing the second mounting block 13322 is a second inclined surface b. One end of the first scraper 131 is located between the first mounting block 13321 and the second mounting block 13322, and abuts against the first inclined surface a and the second inclined surface b respectively. Specifically, the first mounting block 13321 and the second mounting block 13322 are arranged adjacent to each other along the Y direction, and the first mounting block 13321 and the second mounting block 13322 are detachably connected; the surface of the first mounting block 13321 facing the second mounting block 13322 is a first inclined surface a, the second inclined surface b is parallel to the first inclined surface a, and the first inclined surface a forms a first angle with the XY plane, which is not a right angle; the first scraper 131 is mounted through the first mounting block 13321 and the second mounting block 13322, and the first scraper 131 is inclined through the first inclined surface a and the second inclined surface b; in this embodiment, the process of setting the inclined surfaces on the first mounting block 13321 and the second mounting block 13322 is relatively simple, and there is no need to design a more complex structure for the first scraper 131.

[0115] like Figure 7 As shown, in an optional embodiment, the third mounting member 137 includes a connecting plate 1371 and a backing plate 1372. The connecting plate 1371 is connected to the driving end of the first driving member 136. The scraper member 133 is disposed on the connecting plate 1371. One end of the backing plate 1372 is connected to the connecting plate 1371, and the other end of the backing plate 1372 extends away from the first driving member 136, and the other end abuts against the third mounting portion 1332. Specifically, one end of the backing plate 1372 is connected to the connecting plate 1371, and the backing plate 1372 is located between the scraper member 133 and the connecting plate 1371 in the Y direction. The other end of the backing plate 1372 extends downward in the Z direction, and the other end of the backing plate 1372 abuts against the third mounting portion 1332. First, install the backing plate 1372 on the connecting plate 1371. The backing plate 1372 is the reference plate when installing the scraper 133. When installing the scraper 133, the sleeve 1331 of the scraper 133 is installed on the connecting plate 1371, and the third mounting part 1332 of the scraper 133 abuts against the backing plate 1372, which means that the installation position of the scraper 133 is accurate.

[0116] like Figure 7As shown, in an optional embodiment, the printing mechanism 1 further includes a mounting bracket 16, a driving component 15 disposed on the mounting bracket 16, and a doctor blade module 132 slidably connected to the mounting bracket 16. Specifically, the driving component 15 is disposed on the mounting bracket 16, the doctor blade module 132 is connected to the driving end of the driving component 15, and the doctor blade module 132 is slidably connected to the mounting bracket 16 along the Z direction. When the driving component 15 drives the doctor blade module 132 to move along the Z direction, the doctor blade module 132 can slide relative to the mounting bracket 16 in the Z direction, thereby ensuring the stability of the doctor blade module 132's movement in the Z direction and preventing the doctor blade module 132 from deflecting during movement.

[0117] like Figure 8 As shown, in an optional embodiment, the printing mechanism 1 further includes a first sliding member 17 and an oil receiving part 18. The doctor blade module 132 and the mounting bracket 16 are slidably connected through the first sliding member 17. The oil receiving part 18 is disposed on the mounting bracket 16, and the first sliding member 17 and the oil receiving part 18 are arranged opposite to each other. Specifically, the oil receiving part 18 is disposed below the first sliding member 17 in the Z direction. The first sliding member 17 is usually provided with lubricating oil. The oil receiving part 18 is used to receive the lubricating oil dripping from the first sliding member 17 to avoid contaminating other components of the printing mechanism 1.

[0118] For example, the first sliding member 17 includes a guide rail and a slider. The guide rail is mounted on the mounting bracket 16, and the slider is mounted on the scraper module 132. The slider is slidably connected to the guide rail, and lubricating oil is provided between the slider and the guide rail. Alternatively, the first sliding member 17 includes a guide rail and a slider. The slider is mounted on the mounting bracket 16, and the guide rail is mounted on the scraper module 132. The slider is slidably connected to the guide rail, and lubricating oil is provided between the slider and the guide rail.

[0119] For example, the oil receiving part 18 can be an oil receiving pan or an oil receiving trough.

[0120] like Figures 14-20 As shown, in an optional embodiment, the screen assembly 32 includes a screen frame 321 and an ink printing section 322. The ink printing section 322 is disposed on the screen frame 321. At least part of the side of the ink printing section 322 away from the printing mechanism 1 protrudes from the screen frame 321. The ink printing section 322 has a mesh 323 that penetrates the ink printing section 322.

[0121] To further explain, the screen frame 321 has an internal mounting space, the printing part 322 is located within the mounting space, and the printing part 322 is connected to the screen frame 321; at least part of the end of the printing part 322 away from the printing mechanism 1 protrudes from the end face of the screen frame 321; when adhesive needs to be printed, the first drive assembly 31 drives the screen assembly 32 to move closer to the support mechanism 201, and the part of the printing part 322 protruding from the screen frame 321 extends into the space between the screen press 3000. The gap presses against the solder ribbon 2002 or leaves a certain distance between it and the solder ribbon 2002; the printing part 322 is provided with a mesh 323 that penetrates the printing part 322; the dispensing assembly 11 injects glue into the printing part 322; the first scraper assembly 13 moves along the Y direction to squeeze the glue into the mesh 323, and prints it onto the solder ribbon 2002 and the battery cell 2001 through the mesh 323, so as to form glue dots on the battery cell 2001 to fix the solder ribbon 2002.

[0122] like Figure 17 As shown, the printing part 322 includes a protrusion 3221, at least a portion of which protrudes from the bottom end face of the frame 321. The printing part 322 has a mesh hole 323 that passes through the protrusion 3221, and the axis of the mesh hole 323 is the same as the axis in the Z direction. The protrusion 3221 extends into the gap of the pressure mesh 3000 to press the solder ribbon 2002 or leaves a certain gap with the solder ribbon 2002. The dispensing assembly 11 injects glue into the printing part 322, and the glue is printed onto the solder ribbon 2002 and the battery cell 2001 through the mesh hole 323 to form glue dots on the battery cell 2001 to fix the solder ribbon 2002. In the Z direction, the bottom end of the frame 321 facing downward is the bottom of the frame 321.

[0123] like Figure 14 and Figure 17 As shown, in an optional embodiment, the screen printing assembly 32 includes a plurality of printing sections 322, which are spaced apart. Specifically, the plurality of printing sections 322 are spaced apart along the X direction. When a plurality of solder ribbons 2002 are placed on the battery cell 2001, glue is injected into the plurality of printing sections 322 through the dispensing assembly 11. The printing mechanism 1 squeezes the glue from the printing sections 322 into the corresponding mesh openings 323, thereby allowing the plurality of printing sections 322 to dispense glue onto the plurality of solder ribbons 2002.

[0124] like Figure 14As shown, in an optional embodiment, the printing part 322 has a groove 324 formed at one end facing the printing mechanism, and one end of the mesh 323 is located in the groove 324; the first squeegee assembly 13 includes a plurality of first squeegees 131, which are spaced apart, and one first squeegee 131 corresponds to one printing part 322; the second squeegee assembly 14 includes a plurality of second squeegees 141, which are spaced apart, and one second squeegee 141 corresponds to one printing part 322; specifically, since the groove 324 is formed on the printing part 322, when multiple printing parts 322 are provided, one first squeegee 131 squeezes the glue of one printing part 322 into the corresponding mesh 323, so that multiple printing parts 322 can dispense glue onto multiple solder ribbons 2002, and one second squeegee 141 spreads the glue of one printing part 322 evenly on the printing part 322 again.

[0125] To further explain, the printing part 322 has a groove 324 at the end away from the protrusion 3221. The depth direction of the groove 324 is the same as the Z direction. One end of the mesh 323 is located in the groove 324, and the other end of the mesh 323 is located in the protrusion 3221. The inside of the groove 324 is used to contain the glue, and the glue can be prevented from flowing to other areas through the groove 324.

[0126] In another alternative embodiment, the end of the printing portion 322 away from the bottom of the screen frame 321 is a plane. This embodiment is applicable to screen assembly 32 including a printing portion 322, which has a plurality of protrusions 3221. The printing portion 322 has a plurality of mesh holes 323, the positions of which correspond to the positions of the protrusions 3221. One end of the mesh hole 323 is located on the plane, and the other end of the mesh hole 323 is located on the corresponding protrusion 3221.

[0127] like Figure 15 , Figure 18 , Figure 19 and Figure 20 As shown, in an optional embodiment, the printing part 322 includes a body 3222, a first mounting part 3223, and a first elastic member 3225. One end of the first mounting part 3223 is connected to the body 3222. Specifically, the groove 324 is located on the body 3222, and the protrusion 3221 is located on the body 3222, both of which are part of the body 3222. The body 3222 includes a first end and a second end, which are arranged along the Y direction. One end of the first mounting part 3223 is connected to the first end.

[0128] To further explain, the wire frame 321 is provided with a first mounting hole 3211, and the other end of the first mounting part 3223 is provided in the first mounting hole 3211. There is a gap between the first mounting part 3223 and the inner wall of the first mounting hole 3211. The first elastic member 3225 is located between the first mounting part 3223 and the upper wall of the first mounting hole 3211. Specifically, the wire frame 321 is provided with a first mounting hole 3211, and the axis of the first mounting hole 3211 is parallel to the axis in the Y direction (this parallelism means basically parallel, and there can be a certain error). One end of the first mounting part 3223 is provided in the first mounting hole 3211. In the Z direction, a gap is formed between the first mounting part 3223 and the inner wall of the first mounting hole 3211, which allows... The first mounting part 3223 has a certain amount of movement along the Z direction inside the first mounting hole 3211. The first elastic member 3225 is disposed between the first mounting part 3223 and the upper wall of the first mounting hole 3211. The upper wall of the first mounting hole 3211 is part of the inner wall of the first mounting hole 3211. The upper wall of the first mounting hole 3211 refers to the side facing downward in the Z direction. The direction of the elastic force of the first elastic member 3225 is the Z direction. In this embodiment, when the protrusion 3221 extends into the through groove and abuts against the solder strip 2002, the height of the printing part 322 can be adjusted by compressing the first elastic member 3225, and a buffering effect can be provided when the protrusion 3221 abuts against the solder strip 2002.

[0129] In one optional embodiment, a first through hole 3218 is provided at the bottom of the mesh frame 321, and the first through hole 3218 communicates with the first mounting hole 3211. Specifically, the axis of the first through hole 3218 intersects the axis of the first mounting hole 3211, one end of the first through hole 3218 is located at the bottom of the mesh frame 321, and the other end of the first through hole 3218 communicates with the first mounting hole 3211. That is, the other end of the first through hole 3218 is located on the lower wall of the first mounting hole 3211, and the lower wall of the first mounting hole 3211 is part of the inner wall of the first mounting hole 3211. The lower wall of the first mounting hole 3211 refers to the side facing upward in the Z direction.

[0130] Further explanation: the printing part 322 also includes a first limiting part 3226, which passes through the first through hole 3218 and connects to the first mounting part 3223. A first elastic member 3225 is located at the end of the first mounting part 3223 away from the first through hole 3218. Specifically, the first limiting part 3226 passes through the first through hole 3218 at the bottom of the frame 321 and connects to the first mounting part 3223. The end of the first limiting part 3226 away from the first mounting part 3223 is located outside the first through hole 3218, and the first elastic member 3225 is located at the end of the first mounting part 3223 away from the first through hole 3218. When the protrusion 3221 extends into... Inside the channel, the first limiting part 3226 will contact the screen 3000 or other components of the printing station B. In this embodiment, the first limiting part 3226 abuts against the screen 3000 or other components of the printing device 100. The first limiting part 3226 can compress the first elastic member 3225 to adjust the height of the printing part 322. Therefore, the force of compressing the first elastic member 3225 is transferred to the first limiting part 3226, thereby preventing the protrusion 3221 from acting on the solder ribbon 2002 and thus preventing damage to the battery cell 2001. Furthermore, by replacing the first limiting part 3226 with different lengths, the contact or non-contact between the protrusion 3221 and the solder ribbon 2002 can be adjusted.

[0131] like Figure 18 As shown, in one optional embodiment, the wire mesh frame 321 includes a frame 3215 and a first mounting member 3216. The frame 3215 has a first mounting groove 32151, and the first mounting member 3216 is disposed on the frame 3215 and covers the first mounting groove 32151. The first mounting groove 32151 and the first mounting member 3216 form a first mounting hole 3211. Specifically, the wire mesh frame 321 includes a frame 3215, which is formed by a first mounting rod 32153, a second mounting rod 32154, a third mounting rod 32155, and a fourth mounting rod 32156 connected in sequence to form an installation space 3213. The first mounting rod 32153 and the third mounting rod... The second mounting rod 32154 and the fourth mounting rod 32156 are arranged opposite to each other. A first mounting groove 32151 is provided on the frame 3215. The first mounting groove 32151 can be opened on the first mounting rod 32153. The first mounting groove 32151 has an opening facing upward in the Z direction. The first mounting part 3223 is installed into the first mounting groove 32151 at the opening. The first mounting member 3216 is provided on the frame 3215 and covers the opening of the first mounting groove 32151, so that the first mounting part 3223 is located in the first mounting hole 3211. In this embodiment, it is more convenient to install the printing part 322 and the screen frame 321.

[0132] like Figure 16As shown, in an optional embodiment, the printing part 322 further includes a second mounting part 3224 and a second elastic member (not shown in the figure). The second mounting part 3224 and the first mounting part 3223 are respectively located at both ends of the body 3222. One end of the second mounting part 3224 is connected to the body 3222; that is, one end of the second mounting part 3224 is connected to the second end of the body 3222.

[0133] Further explanation: the wire frame 321 is provided with a second mounting hole 3212, and the other end of the second mounting part 3224 is provided in the second mounting hole 3212. There is a gap between the second mounting part 3224 and the inner wall of the second mounting hole 3212. The second elastic member is located between the second mounting part 3224 and the upper wall of the second mounting hole 3212. Specifically, the wire frame 321 is provided with a second mounting hole 3212, and the axis of the second mounting hole 3212 is parallel to the axis in the Y direction (this parallelism means basically parallel, and there can be a certain error). The second mounting hole 3212 is arranged opposite to the first mounting hole 3211. One end of the second mounting part 3224 is provided in the second mounting hole 3212. In the Z direction, a gap is formed between the second mounting part 3224 and the inner wall of the second mounting hole 3212, which allows the second mounting part 3224 to... Inside the second mounting hole 3212, there are two movable parts that move along the Z direction. The second elastic member is disposed between the second mounting part 3224 and the upper wall of the second mounting hole 3212. The upper wall of the second mounting hole 3212 is part of the inner wall of the second mounting hole 3212. The upper wall of the second mounting hole 3212 refers to the side facing downward in the Z direction. The direction of the elastic force of the second elastic member is the Z direction. In this embodiment, when the protrusion 3221 extends into the through groove and abuts against the solder strip 2002, the height of the printing part 322 can be adjusted by compressing the second elastic member, and a buffering effect can be provided when the protrusion 3221 abuts against the solder strip 2002. Furthermore, both ends of the body 3222 can be adjusted by the first elastic member 3225 and the second elastic member to avoid the body 3222 from tilting.

[0134] In one optional embodiment, a second through hole (not shown in the figure) is provided at the bottom of the mesh frame 321. The second through hole communicates with the second mounting hole 3212. The first through hole 3218 is spaced apart from the second through hole. The axis of the second through hole intersects the axis of the second mounting hole 3212. One end of the second through hole is located at the bottom of the mesh frame 321, and the other end of the second through hole communicates with the second mounting hole 3212. That is, the other end of the second through hole is located on the lower wall of the second mounting hole 3212. The lower wall of the second mounting hole 3212 is part of the inner wall of the second mounting hole 3212. The lower wall of the second mounting hole 3212 refers to the side facing upward in the Z direction.

[0135] Further explanation: the printing part 322 also includes a second limiting part 3227, which passes through the second through hole and connects to the second mounting part 3224. The second elastic member is located at the end of the second mounting part 3224 away from the second through hole. Specifically, the second limiting part 3227 passes through the second through hole at the bottom of the frame 321 and connects to the second mounting part 3224. The end of the second limiting part 3227 away from the second mounting part 3224 is located outside the second through hole, and the second elastic member is located at the end of the second mounting part 3224 away from the second through hole. When the protrusion 3221 extends into the through groove, the second limiting part 3227... 27 will come into contact with the screen 3000 or other components of the printing station; in this embodiment, the second limiting part 3227 abuts against the screen 3000 or other components of the printing device 100, and the second elastic member can be compressed by the second limiting part 3227 to adjust the height of the printing part 322. Therefore, the force of compressing the second elastic member is transferred to the second limiting part 3227, thereby preventing the protrusion 3221 from acting on the solder ribbon 2002, and thus preventing damage to the battery cell 2001; and by replacing the second limiting part 3227 of different lengths, the contact or non-contact between the protrusion 3221 and the solder ribbon 2002 can be adjusted.

[0136] In one optional embodiment, the frame 321 includes a frame 3215 and a second mounting member 3217. The frame 3215 has a second mounting groove 32152, and the second mounting member 3217 is disposed on the frame 3215 and covers the second mounting groove 32152. The second mounting groove 32152 and the second mounting member 3217 form a first mounting hole 3211. Specifically, the frame 3215 has a second mounting groove 32152, which can be formed on a third mounting rod 32155. The second mounting groove 32152 has an opening facing upward in the Z direction. A second mounting part 3224 is mounted in the second mounting groove 32152 at the opening. The second mounting member 3217 is disposed on the frame 3215 and covers the opening of the second mounting groove 32152, so that the second mounting part 3224 is located in the second mounting hole 3212. In this embodiment, it is more convenient to install the printing part 322 and the frame 321.

[0137] like Figure 5 , Figure 21 and Figure 22As shown, in an optional embodiment, the printing apparatus 100 further includes a cleaning mechanism 4, which includes a second driving component 41 and a cleaning component 42. The cleaning component 42 is disposed at the driving end of the second driving component 41 and is located on the side of the screen assembly 32 away from the printing mechanism 1. The cleaning component 42 is used to clean the end of the screen assembly 32 away from the printing mechanism 1. Specifically, the cleaning component 42 is connected to the driving end of the second driving component 41, and the second driving component 41 can drive the cleaning component 42 to move in the X direction to clean the glue residue on the screen assembly 32, so that the bottom surface of the screen assembly 32 is free of printing glue after a large number of prints.

[0138] like Figure 21 and Figure 22 As shown, in an optional embodiment, the second drive assembly 41 includes a second drive member 411 and a mounting bracket 412. The mounting bracket 412 is disposed at the drive end of the second drive member 411, and the cleaning assembly 42 is rotatably connected to the mounting bracket 412. Specifically, the mounting bracket 412 is disposed at the drive end of the second drive member 411, and the cleaning assembly 42 is rotatably connected to the mounting bracket 412. The second drive member 411 can drive the mounting bracket 412 and the cleaning assembly 42 to move in the X direction. When the cleaning assembly 42 cleans the screen assembly 32, the second drive member 411 drives the mounting bracket 412 and the cleaning assembly 42 to move in the X direction. The cleaning assembly 42 contacts the screen assembly 32, and the cleaning assembly 42 can rotate around its own axis through friction, thereby improving the uniformity of the cleaning surface of the cleaning assembly 42, thus improving the service life and cleaning effect of the cleaning assembly 42.

[0139] The axis of the cleaning component 42 is parallel to the axis in the Y direction.

[0140] like Figure 21 and Figure 22 As shown, in an optional embodiment, the cleaning assembly 42 includes a cleaning roller 421 and a mounting shaft 422, with the mounting shaft 422 disposed at one end of the cleaning roller 421; specifically, the cleaning roller 421 is used to clean the screen assembly 32, and the mounting shaft 422 is disposed at one end of the cleaning roller 421, with the axis of the mounting shaft 422 coinciding with the axis of the cleaning roller 421.

[0141] To further explain, the mounting frame 412 includes a first mounting plate 4121 and a second mounting plate 4122. The first mounting plate 4121 and the second mounting plate 4122 are spaced apart along the axial direction of the mounting shaft 422. The mounting shaft 422 is rotatably connected to the first mounting plate 4121 via a first bearing 413, and the mounting shaft 422 is rotatably connected to the second mounting plate 4122 via a second bearing 414. Specifically, the mounting shaft 422 is rotatably connected to the first mounting plate 4121 via the first bearing 413, and the mounting shaft 422 is rotatably connected to the second mounting plate 4122 via the second bearing 414. This ensures the rotational stability of the mounting shaft 422, which in turn ensures the rotational stability of the cleaning roller 421, thereby improving the cleaning effect of the cleaning assembly 42.

[0145] According to a second aspect of the embodiments of this application, a method for preparing a photovoltaic module 2000 is provided. The method for preparing the photovoltaic module 2000 can employ the above-described printing system 1000, and the method includes:

[0146] S1, place the welding ribbon 2002 on the solar cell 2001;

[0147] S2, the welding ribbon 2002 and the battery cell 2001 are fixed together by adhesive dots to form a first assembly.

[0148] Further explanation: The preparation method includes S1 and S2; in step S1, the welding ribbon 2002 is placed on the battery cell 2001 by the feeding mechanism 302, and the carrying mechanism 201 moves the welding ribbon 2002 and the battery cell 2001 to the printing station B; in step S2, the welding ribbon 2002 and the battery cell 2001 can be fixed by the adhesive dots through the printing process or by directly applying adhesive to the welding ribbon 2002 and the battery cell 2001, thereby forming the first assembly.

[0149] In this embodiment, the solder ribbon 2002 is first placed on the solar cell 2001, and then the solder ribbon 2002 and the solar cell 2001 are fixed by adhesive dots. This does not affect the arrangement of the adhesive dots, and the solder ribbon 2002 is in direct contact with the solar cell 2001. It does not affect the contact area between the solder ribbon 2002 and the grid lines. Therefore, the current extraction efficiency can be improved, thereby improving the quality of the photovoltaic module 2000.

[0150] In an optional embodiment, the preparation method further includes S3, which involves curing the first assembly with adhesive to form a second assembly; specifically, the first assembly is cured with adhesive using a curing device 500 to form the second assembly, wherein the solder ribbon 2002 of the second assembly can completely adhere to the battery cell 2001 and can improve the connection stability between the solder ribbon 2002 and the battery cell 2001.

[0151] Excluding the grid 3000, the second assembly is the photovoltaic module 2000.

[0152] In an optional embodiment, in S1, the pressure mesh 3000 is placed on the welding ribbon 2002; specifically, the feeding mechanism 302 moves the pressure mesh 3000 located in the second buffer area 800 to the feeding station A, and the pressure mesh 3000 presses on the welding ribbon 2002 to prevent the welding ribbon 2002 from shifting.

[0153] In one optional embodiment, the preparation method further includes:

[0154] S3, the first assembly is cured with adhesive to form the second assembly;

[0155] S4, the pressure mesh 3000 of the second assembly is removed to form a photovoltaic module 2000.

[0156] Further explanation: In step S3, the first assembly is cured with adhesive by the curing device 500 to form the second assembly. The solder ribbon 2002 of the second assembly can completely adhere to the solar cell 2001, and can improve the connection stability between the solder ribbon 2002 and the solar cell 2001. In step S4, the pressure mesh 3000 of the second assembly is removed by the transport device 600 to form the photovoltaic module 2000. In this embodiment, before the adhesive of the first assembly is cured, the solder ribbon 2002 is pressed tightly by the pressure mesh 3000, and then the adhesive is cured to prevent the solder ribbon 2002 from not being completely adhered to the solar cell 2001 during curing. After curing is completed, the transport device 600 removes the pressure mesh 3000.

[0157] like Figures 23-25 As shown, according to a third aspect of the embodiments of this application, a photovoltaic module 2000 is provided, including a solar cell 2001, a solder ribbon 2002, and a plurality of adhesive layers 2003. The solder ribbon 2002 is placed on the solar cell 2001, and the plurality of adhesive layers 2003 are spaced apart along the length direction of the solder ribbon 2002. Along the width direction of the solder ribbon 2002, the adhesive layers 2003 cover the solder ribbon 2002 and partially cover the solar cell 2001 on both sides of the solder ribbon 2002; the width direction and the length direction intersect (see attached figure). Figure 23 (The marked direction).

[0158] like Figures 23-25 As shown, the photovoltaic module 2000 includes a cell 2001, a solder ribbon 2002, and multiple adhesive layers 2003; wherein, the solder ribbon 2002 is placed on the cell 2001 and is bonded to the cell 2001, and the adhesive layers 2003 are used to fix the solder ribbon 2002 and the cell 2001 together.

[0159] Specifically, multiple adhesive layers 2003 are spaced apart along the length of the solder strip 2002, and the multiple adhesive layers 2003 fix the solder strip 2002 to the battery cell 2001 along the length of the solder strip 2002, which can improve the connection stability between the solder strip 2002 and the battery cell 2001.

[0160] To further explain, along the width direction of the solder ribbon 2002, the adhesive layer 2003 covers the solder ribbon 2002, and the adhesive layer 2003 also partially covers the solar cell 2001. It can be understood that, along the width direction of the solder ribbon 2002, the adhesive layer 2003 covers the solar cell 2001 on both sides of the solder ribbon 2002, thereby ensuring that the adhesive layer 2003 can fix the solder ribbon 2002 to the solar cell 2001.

[0161] The photovoltaic module 2000 of this application does not affect the arrangement position of the adhesive layer 2003, and the solder ribbon 2002 is in direct contact with the cell 2001, which does not affect the contact area between the solder ribbon 2002 and the grid line. Therefore, it can improve the current conduction efficiency, thereby improving the quality of the photovoltaic module 2000.

[0162] The photovoltaic module 2000 can be prepared using the above-mentioned method for preparing the photovoltaic module 2000, and the photovoltaic module 2000 can be processed using the above-mentioned printing system 1000.
