Description

Technical Field

[0001] Embodiments of the present application relate to the technical field of photovoltaic cell string production equipment. Specifically, the present application relates to a shaping component, a carrying module, a cell string carrying mechanism, and a string welding machine. Background Art

[0002] When assembling existing back-contact cell strings, generally, the solder ribbon group is first laid on the carrying mechanism at the string assembly station, and then the cell group is laid on the solder ribbon group. An adsorption component is provided on the carrying mechanism to adsorb the laid solder ribbon group and cell group.

[0003] The solder ribbon group is generally transported to the carrying mechanism by a plurality of jaws of a handling mechanism simultaneously clamping both ends of each solder ribbon and then released by the jaws of the handling mechanism, and the solder ribbon group falls on the carrying mechanism. Since the solder ribbon is very thin, it is easy to shift during the process of falling from the jaws of the handling mechanism to the carrying mechanism by its own weight, resulting in the situation that the grid lines of the cells in the assembled cell string are exposed. Summary of the Utility Model

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. For this reason, the present application provides a shaping component, a carrying module, a cell string carrying mechanism, and a string welding machine to ensure the accurate positioning of the solder ribbon during the string assembly operation and avoid the probability of the grid lines of the cells in the assembled cell string being exposed.

[0005] To solve the above problems, the technical solutions adopted in the present application are as follows:

[0006] In a first aspect, an example of the present application provides a shaping component, which includes a support, a limiting member, and a reset member, where:

[0007] An installation groove is formed on the support, and the limiting member and the reset member are arranged in the installation groove;

[0008] There are n limiting members, and limiting grooves are formed at the tops of the n limiting members. Each limiting groove is for a solder ribbon extending along a first direction to fall into, and the limiting groove is configured to limit the movement amount of the falling solder ribbon along a second direction, and the second direction is perpendicular to the first direction on a horizontal plane;

[0009] The reset member is configured to drive the corresponding n limiting members to rise to a first position along the vertical direction, so that the limiting grooves on the n limiting members partially protrude from the upper surface of the support;

[0010] After the cell is pressed on the n limiting members, the n limiting members are pressed down to a second position by the cell along the vertical direction, so that the solder ribbon limited by the limiting groove fits the lower surface of the cell;

[0011] After the battery cell and the welding ribbon are separated from the regularization assembly, the reset member drives the corresponding n limit members to return from the second position to the first position in the vertical direction.

[0012] For the regularization assembly provided in this application, each regularization assembly includes n limit members. The limit grooves (limit members) on each regularization assembly perform independent extending and descending actions relative to the limit grooves (limit members) of other regularization assemblies to receive the welding ribbon and regularize the position of the welding ribbon, and cooperate with the downward pressing of the battery cell to make the welding ribbon fit the lower surface of the battery cell. Compared with the method in the related art where the same structure or related structure drives the welding ribbon guiding structure to lift for position regularization, this solution helps to avoid the mutual influence between the limit grooves (limit members) and reduce the accuracy of welding ribbon position regularization.

[0013] Moreover, the reset member can drive the limit grooves (limit members) in the vertical direction, enabling the limit grooves (limit members) to extend and descend vertically relative to the bearing surface. This method helps to avoid scratching the battery cell.

[0014] According to some examples of the first aspect of this application, the regularization assembly further includes a panel located above the installation groove. The panel is detachably connected to the support, and the panel and the support cooperate to enclose the installation groove;

[0015] The limit member includes an upper part and a lower part connected in the vertical direction. The limit groove is located in the upper part of the limit member. The dimension of the upper part of the limit member in the first direction is smaller than the dimension of the lower part of the limit member in the first direction. A guiding opening for the upper part of the limit member to fit through is provided on the panel;

[0016] When the limit member is driven by the reset member to rise, the upper part of the limit member passes through the guiding opening on the panel, and the lower part of the limit member abuts against the lower surface of the panel.

[0017] Configuring a panel above the installation groove to enclose the installation groove helps to reduce the exposed gap. Therefore, debris is not easily introduced into the interior of the regularization assembly, which helps to avoid mechanism jamming. Moreover, the lower part of the limit member cooperates with the panel to achieve limiting and braking, while the upper part of the limit member can pass through the guiding opening provided on the panel to make the limit groove partially protrude to regularize the welding ribbon. The detachable connection between the panel and the support also facilitates replacement and maintenance operations.

[0018] According to some examples of the first aspect of this application, the regularization assembly further includes a first magnetic component. The first magnetic component is provided on at least one of the bottom of the panel and the upper surface of the lower part of the limit member. The panel or the lower part of the limit member is made of ferromagnetic material. The magnetic adsorption of the first magnetic component positions the limit member at the first position, and after the battery cell is pressed on the n limit members, the limit member is pressed down to the second position.

[0019] The magnetic adsorption of the first magnetic component (for example, the magnetic adsorption of the first magnetic component arranged on the upper surface of the lower half of the limiting member to the bottom of the panel, the magnetic adsorption of the first magnetic component arranged on the bottom of the panel to the upper surface of the lower half of the limiting member, or the magnetic adsorption between the first magnetic component arranged on the upper surface of the lower half of the limiting member and the first magnetic component arranged on the bottom of the panel) helps to ensure that the limiting member is accurately and stably positioned at the first position.

[0020] According to some examples of the first aspect of the present application, one end of the reset member abuts against the bottom of the installation groove, and the other end abuts against the limiting member. The reset member is made of an elastic material;

[0021] When the n limiting members are pressed down to the second position by the battery cell in the vertical direction, the reset member is pushed down and compressed by the n limiting members;

[0022] After the battery cell and the welding tape are separated from the rectifying assembly, the reset member lifts the n limiting members from the second position to the first position in the vertical direction through its own elastic force.

[0023] The reset member made of elastic material has an elastic force, which acts on the limiting member and descends along the vertical direction when being pressed by the battery cell, and lifts under the action of the elastic force after being separated from the pressing of the battery cell. This driving method is simple.

[0024] According to some examples of the first aspect of the present application, the rectifying assembly further includes a second magnetic component, and the second magnetic component is arranged on at least one of the bottom of the installation groove and the bottom of the limiting member. The part corresponding to the second magnetic component on the bottom of the installation groove or the bottom of the limiting member is made of a ferromagnetic material, and the magnetic adsorption of the second magnetic component positions the limiting member at the second position, and when an external force is applied to the limiting member, the limiting member is lifted to the first position.

[0025] The magnetic adsorption of the second magnetic component (for example, the magnetic adsorption of the second magnetic component arranged on the bottom of the limiting member to the bottom of the installation groove, the magnetic adsorption of the second magnetic component arranged on the bottom of the installation groove to the bottom of the limiting member, or the magnetic adsorption between the second magnetic component arranged on the bottom of the limiting member and the second magnetic component arranged on the bottom of the installation groove) helps to ensure that the limiting member is accurately and stably positioned at the second position, and when an external force is applied to the limiting member, the positioning effect of the magnetic adsorption is released, and the limiting member is lifted to the first position under the action of the external force.

[0026] According to some examples of the first aspect of the present application, the inner wall of the notch of the limiting groove is in a slope shape in the second direction.

[0027] The groove hole in a slope shape is conducive to the welding tape falling into the bottom of the limiting groove more smoothly.

[0028] According to some examples of the first aspect of the present application, the n limit members are independent of each other, and the number of reset members is configured to be n. The n reset members are arranged in one-to-one correspondence with the n limit members, and each reset member is configured to drive the corresponding limit member to be in the first position.

[0029] The n limit members arranged along the second direction are independent of each other, which can ensure that each limit member is independently driven to lift and lower, thereby avoiding the mutual influence between the limit members and reducing the accuracy of the position regularization of the solder tape.

[0030] In a second aspect, an example of the present application provides a carrier module. The carrier module includes a carrier body and at least two regularization components. The at least two regularization components are arranged on the carrier body at intervals along a first direction, and the support and the carrier body are of an integral structure or a split structure. The upper surface of the regularization component is flush with the upper surface of the carrier body, and the i-th limit slots of each regularization component along the second direction jointly define a solder tape.

[0031] The carrier module arranges at least two regularization components on the carrier body at intervals along the first direction. Each regularization component has a row of limit members (each row has n limit members), so as to regularize the position of the solder tape laid on the carrier module, make the position of the carried solder tape accurate, thereby ensuring that each solder tape is located at a preset position, reducing the probability of the grid lines of the battery cells showing white during the stringing operation, and further reducing the defective rate of the battery string soldering and improving the soldering quality of the battery string.

[0032] According to some examples of the second aspect of the present application, a plurality of rows of receiving grooves are further formed on the upper surface of the carrier body. Each row of receiving grooves extends along the first direction and is collinear. Each row of receiving grooves corresponds to a solder tape extending along the first direction. The i-th limit slot arranged by each regularization component along the second direction is located between two adjacent receiving grooves in the i-th row of receiving grooves;

[0033] An anti-adhesive strip is laid in the receiving groove. The upper surface of the anti-adhesive strip is flush with the upper surface of the carrier body. The anti-adhesive strip is configured to carry the solder tape extending along the first direction;

[0034] The anti-adhesive strip is made of Teflon material.

[0035] The two receiving grooves in the same row and the limit slot between the two receiving grooves are collinear, corresponding to the position where a solder tape falls. Laying an anti-adhesive strip made of Teflon material in the receiving groove helps to avoid solder adhesion during welding.

[0036] According to some examples of the second aspect of the present application, the carrier module further includes an adsorption component. The adsorption component includes a plurality of adsorption heads arranged on the carrier body and a negative pressure device communicated with the adsorption heads. The adsorption heads adsorb the battery cells under the action of the negative pressure device;

[0037] The suction heads are lower than the upper surface of the carrying body. The suction heads are arranged in rows, and at least one row of suction heads is distributed between two adjacent regular components.

[0038] By using the cooperation of multiple suction heads and a negative pressure device, the stability of the positions of the battery cells and the welding tapes is ensured, the coverage area of the negative pressure suction holes is increased, and thus the adsorption stability and reliability of the adsorption assembly are improved.

[0039] According to some examples of the second aspect of the present application, the carrying module further includes a heating component. The heating component is located inside the carrying body and is used to heat the carrying body and the battery cells and welding tapes carried thereon.

[0040] The use of the heating component realizes the automatic heating function for the battery cell group and the welding tape group carried by the carrying body.

[0041] According to some examples of the second aspect of the present application, the n limit pieces of each regular component are integrally provided. The carrying module further includes two sets of tilting components. The two sets of tilting components are respectively arranged at both ends of the carrying body along the second direction. Each set of tilting components includes a connecting plate, a fixing part, and a tilting plate, where:

[0042] Each tilting plate is rotatably mounted on the corresponding fixing part. Each connecting plate extends along the first direction, and each connecting plate is fixedly connected to the n limit pieces of at least two regular components respectively;

[0043] The first end of the tilting plate abuts against the lower surface of the connecting plate. When the second end of the tilting plate is driven, the tilting plate rotates so that the first end of the tilting plate applies an external force to the connecting plate, and the limit piece connected to the connecting plate is jacked up to the first position under the action of the external force.

[0044] By configuring rotatable tilting plates at both ends of the carrying body, it is convenient to drive one end of the tilting plate so that the other end applies an external force to the limit piece, thereby lifting the limit piece connected to the tilting plate to a high position, and performing operations such as dropping the welding tape in the high position state.

[0045] In a third aspect, an example of the present application provides a battery string carrying mechanism. The battery string carrying mechanism includes a base and a plurality of carrying modules. The plurality of carrying modules are arranged in a row along the first direction on the base. The plurality of carrying modules are detachably mounted on the base and are configured to carry a plurality of battery cells and a plurality of welding tapes.

[0046] The detachable cooperation relationship between the carrying module and the base facilitates flexible assembly and maintenance. And the battery string carrying mechanism with this structure is convenient for stably receiving the battery cells and the welding tapes, and transporting the received battery cells and welding tapes to a fixed station for welding, ensuring the stability of the performance of the welded battery string.

[0047] In a fourth aspect, an example of the present application provides a string welding machine, which includes a solder tape handling mechanism, a cell handling mechanism, a fixing mechanism, a battery string carrying mechanism, and a conveying mechanism, where:

[0048] The string welding machine is sequentially provided with a stringing station and a fixing station in a first direction. The driving end of the conveying mechanism is connected to the battery string carrying mechanism, and the conveying mechanism is configured to drive the battery string carrying mechanism to alternately move to the stringing station and the fixing station. The solder tape handling mechanism and the cell handling mechanism are both arranged at the stringing station, and the fixing mechanism is arranged at the fixing station;

[0049] When the conveying mechanism drives the battery string carrying mechanism to move to the stringing station, the solder tape handling mechanism is configured to lay a plurality of solder tapes on the battery string carrying mechanism, and the plurality of solder tapes respectively fall into corresponding limiting grooves. The cell handling mechanism is configured to lay a plurality of cells on each carrying module to perform stringing;

[0050] When the conveying mechanism drives the battery string carrying mechanism to move to the fixing station, the fixing mechanism is configured to fix a plurality of solder tapes and cells that have been strung on the battery string carrying mechanism together.

[0051] Through the cooperation of the solder tape handling mechanism, the cell handling mechanism, the fixing mechanism, the battery string carrying mechanism, and the conveying mechanism, the stringing and string welding of the cell group and the solder tape group are realized, and the working efficiency is high; the regularizing component in the battery string carrying mechanism can regularize each solder tape at the stringing station, so that each solder tape is located at a preset position, to avoid the white exposure of the cell grid lines caused by the offset of the solder tape, thereby reducing the defective rate of the battery string string welding and improving the string welding quality of the battery string.

[0052] According to some examples of the fourth aspect of the present application, the involved carrying module includes two sets of tilting components as described above. The solder tape handling mechanism includes a driving module and a plurality of handling components, where:

[0053] The number of the handling components is the same as the number of the carrying modules. The handling component includes two elastic pressing rods and a handling part. The handling part is configured to pick up or release a plurality of solder tapes. The two elastic pressing rods are respectively located on both sides of the handling part along a second direction, and the lower ends of the two elastic pressing rods protrude downward from the handling part;

[0054] The driving module is configured to drive a plurality of handling parts to move to the solder tape feeding place and pick up a plurality of solder tapes. The driving module is further configured to drive a plurality of handling components to move to directly above the battery string carrying mechanism and descend. The two elastic pressing rods of each handling component first respectively push down the second ends of the two tilting plates on the carrying module, and the second ends of the tilting plates drive the first ends of the tilting plates to tilt upward so that the limiting parts are lifted to a first position. Then, the plurality of handling components sequentially place the solder tapes into the corresponding limiting grooves.

[0055] When the elastic pressure rods arranged on both sides of the solder tape handling mechanism abut against the second ends of the corresponding tilting plates, it can ensure that the limiting members stay stably at the high position. At this time, when the solder tape handling mechanism places the solder tape again, it can avoid the situation that the solder tape rubs against the edge of the limiting groove or is stuck by the limiting members, which is beneficial to accurately dropping the solder tape into the limiting groove. After the accurate dropping of the solder tape is completed, the solar cell handling mechanism transports the solar cell to the solar cell string bearing mechanism, and the solar cell abuts against the limiting member and pushes the limiting member downward. The limiting member descends to a position flush with the solder tape, so that the solder tape fits against the lower surface of the solar cell. At this time, the limiting member is in the second position. Description of the Drawings

[0071] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0072] Figure 1 A schematic diagram of the structure of a battery string support mechanism provided in an embodiment of the present application, Figure 2 It is a structural schematic diagram of the battery string connection method in the embodiment of the present application.

[0073] Combination Figure 1 and Figure 2 As shown, the photovoltaic cell string is formed by stacking the cells 3 and the welding strips 4 in a predetermined order by a string welding machine and then welding them together. The cells 3 are arranged in sequence along a first direction, the welding strips 4 have a length along the first direction, and multiple welding strips 4 of the same group are arranged in a second direction (perpendicular to the first direction) at intervals, and two adjacent cells 3 are connected together by a group of welding strips 4. Before welding, the cell string carrying mechanism is usually used to receive the cell 3 and the welding strips 4 and string them together. Figure 2, when the solar cells 3 and the solder tapes 4 are assembled into a string, generally, the solder tape group is first laid on the cell string bearing mechanism at the stringing station, then the solar cell group is laid on the solder tape group, and then transferred to the fixing station for processing to achieve the fixed connection between the solar cells 3 and the solder tapes 4. Multiple solar cells 3 can form a cell string through the grouped solder tapes 4, and the grid lines on the back of each solar cell 3 are connected in series through the solder tapes 4. The processing of the solar cell group and the solder tape group at the fixing station can be glue dot curing, heat curing, uv curing, etc., as long as the solder tape 4 and the grid lines on the back of the solar cell 3 are fixed together.

[0074] The solder tape handling mechanism configured on the current string welding machine generally moves the solder tape 4 to above the cell string bearing mechanism by clamping and then releases the solder tape 4. Since the solder tape 4 is very thin, it is easy to deviate during the process of the solder tape falling onto the bearing mechanism by its own weight after leaving the clamping jaw of the handling mechanism, resulting in the situation that the grid lines of the solar cells are exposed white in the cell string after stringing, seriously affecting the string welding quality of the solder tape and the solar cells.

[0075] Therefore, this embodiment provides a rectifying component 22, a bearing module 2, a cell string bearing mechanism and a string welding machine to ensure the accurate positioning of the solder tape 4 during the stringing operation and avoid the probability of the grid lines of the solar cells being exposed white in the cell string after stringing.

[0076] The following Figures 1 to 10 further describes the relevant structures and working principles (action processes) of the rectifying component 22, the bearing module 2, the cell string bearing mechanism and the string welding machine provided by the embodiments of the present application.

[0077] Referring to Figure 3 and Figure 4 and combining with Figure 1 and Figure 2 As shown, an embodiment of the present application provides a rectifying component 22, which includes a support 221, n limiting members 222, and a reset member 223, where:

[0078] An installation groove 2211 is formed on the support 221, and both the limiting members 222 and the reset member 223 are arranged in the installation groove 2211; the n limiting members 222 are usually arranged in a row. For example, the n limiting members 22 are arranged in sequence along the second direction, and a limiting groove 2221 is formed at the top of each limiting member 222. Each limiting groove 2221 is for a solder tape 4 to fall into. The limiting groove 2221 is configured to limit the movement amount of the falling solder tape 4 in the second direction to ensure that the position of the falling solder tape 4 is restricted and does not deviate. n can be 12, 14, 18, 20, 24, 26, 28 or more, and the number of solder tapes in each solder tape group is 6, 7, 8, 9, 10, 11, 12, 13, 14 or other numbers of common solder tape groups. Just matching the number of configured limiting members 222 with the number of solder tapes 4 arranged along the second direction is fine;

[0079] The reset member 223 drives the corresponding n limiting members 222 to rise to the first position in the vertical direction. When the n limiting members 222 are in the first position, the limiting grooves 2221 formed thereon partially protrude from the upper surface of the support 221 to ensure that the welding tape 4 can fall into the limiting grooves 2221;

[0080] After the welding tape 4 falls into the corresponding limiting grooves 2221, the battery cell is then pressed onto the n limiting members 222, and the n limiting members 222 are pressed down to the second position in the vertical direction by the battery cell. When the n limiting members 222 are in the second position, the portions of the n limiting members 222 protruding from the upper surface of the support 221 are lower than the welding tape 4 or flush with the upper surface of the welding tape 4, and the welding tape 4 defined by the corresponding limiting grooves 2221 can be attached to the lower surface of the battery cell 3; moreover, after the battery cell 4 and the welding tape 3 are separated from the regularizing assembly 22, the reset member 223 drives the corresponding n limiting members 222 to reset, that is, to return from the second position to the first position in the vertical direction.

[0081] In this embodiment, the limiting members 222 (n limiting grooves 2221) on each regularizing assembly 22 can perform independent extending and descending actions relative to the limiting members 222 (n limiting grooves 2221) of other regularizing assemblies 22. After receiving the welding tape 4, the position of the welding tape 4 is limited by the limiting grooves 2221 to ensure that the welding tape 4 does not deviate in the second direction, and the regularizing assembly 22 also cooperates with the pressing of the battery cell 3 to make the welding tape 4 and the lower surface of the battery cell 3 fit. Compared with the prior art method in which the guiding structure driving the welding tape 4 is lifted and lowered by the same structure or related structure to implement position regularization, this solution helps to avoid the mutual influence between the limiting members 222 (n limiting grooves 2221) and reduce the accuracy of the welding tape 4 position regularization.

[0082] Moreover, the reset member 223 can drive the limiting members 222 (n limiting grooves 2221) in the vertical direction, so that the limiting members 222 (n limiting grooves 2221) can extend and descend vertically relative to the bearing surface, and the top surface of the limiting members 222 will not slide relative to the surface of the battery cell. This method helps to avoid scratching the battery cell.

[0083] Refer to Figure 5 and Figure 6 and in combination with Figure 3 and Figure 4As shown, in some embodiments, the regularization component 22 further includes a panel 224 located above the mounting groove 2211. The panel 224 is detachably connected to the support 221. The panel 224 and the support 221 cooperate to close the mounting groove 2211, thereby reducing the exposed gap and preventing debris from entering the interior of the regularization component 22 and causing the mechanism to jam. Moreover, in this embodiment, the limiting member 222 includes an upper half portion 2222 and a lower half portion 2223 connected in the vertical direction. The limiting groove 2221 is located in the upper half portion 2222 of the limiting member 222. The dimension of the upper half portion 2222 of the limiting member 222 in the first direction is smaller than the dimension of the lower half portion 2223 of the limiting member 222 in the first direction. A guiding opening 2241 is formed on the panel 224 for the upper half portion 2222 of the limiting member 222 to fit through. Such a structural cooperation ensures that the upper half portion 2222 of the limiting member 222 can pass through the guiding opening 2241 provided on the panel 224 to make the limiting groove 2221 partially protrude to regularize the welding tape, while the lower half portion 2223 of the limiting member 222 cooperates with the panel 224 to achieve limiting and braking. Specifically, when the limiting member 222 is driven by the reset member 223 to rise, the upper half portion 2222 of the limiting member 222 passes through the guiding opening 2241 on the panel 224, and the lower half portion 2223 of the limiting member 222 abuts against the lower surface of the panel 224. The detachable connection setting of the panel 224 and the support 221 also facilitates the maintenance of the mechanism and the replacement operation of components. It should be noted that for the clear description of the embodiments, Figure 6 the support 221 and the bearing body 21 are schematically distinguished. The support 221 and the bearing body 21 can be an integral structure to reduce the number of components, thereby reducing the influence of excessive component assembly on the accuracy.

[0084] To accurately and stably position the limiting member 222 at the first position and the second position, in specific implementation, magnetic components can also be configured for the limiting member 222, the panel 224, and the mounting groove 2211 of the support 221 to generate magnetic adsorption, and the accurate and stable positioning is achieved by means of magnetic adsorption. The following combines Figure 7 and Figure 8 to further describe the configuration of the magnetic components.

[0085] Referring to Figure 8As shown in the figure, as an example of using the magnetic adsorption of the first magnetic component 225 to achieve the positioning of the first position, the first magnetic component 225 can be arranged on the upper surface of the lower half 2223 of the limiting component 222 to generate magnetic adsorption on the bottom of the panel 224 made of ferromagnetic material; the first magnetic component 225 can also be arranged on the bottom of the panel 224, and when the lower half 2223 of the limiting component 222 is made of ferromagnetic material, the first magnetic component 225 generates magnetic adsorption on the upper surface of the lower half 2223; the first magnetic component 225 can also be arranged on the upper surface of the lower half 2223 of the limiting component 222 and the bottom of the panel 224 at the same time to generate magnetic adsorption between the two. When the limiting component 222 is in the first position, the magnetic adsorption of the first magnetic component 225 accurately and stably positions the limiting component 222 at the first position. After the battery cell is pressed on the n limiting components 222, the limiting component 222 is pressed down to the second position.

[0086] Referring to Figure 7 and Figure 8 As shown in the figure, in some embodiments, in order to accurately and stably position the limiting component 222 at the second position, the regularizing component 22 further includes a second magnetic component 226. As an example of using the magnetic adsorption of the second magnetic component 226 to achieve the positioning of the limiting component 222 at the second position, the second magnetic component 226 can be arranged at the bottom of the limiting component 222 and generate magnetic adsorption with the bottom of the mounting groove 2211 made of ferromagnetic material, or the second magnetic component 226 can be arranged at the bottom of the mounting groove 2211 and generate magnetic adsorption on the bottom of the limiting component 222 made of ferromagnetic material, or the second magnetic component 226 can be arranged at the bottom of the limiting component 222 and the bottom of the mounting groove 2211 at the same time to generate magnetic adsorption between the two. These examples all help to ensure that the limiting component 222 is accurately and stably positioned at the second position. When an external force is applied to the limiting component 222, the positioning effect of the magnetic adsorption is released, and the limiting component 222 is pushed up to the first position by the external force. It should be understood that the method of using the magnetic adsorption generated by the second magnetic component 226 for accurate and stable positioning can also be a combination of two or more of the above three methods.

[0087] Referring to Figure 4 , Figures 6 to 8As shown, in some embodiments, one end of the reset member 223 abuts against the bottom of the mounting groove 2211, and the other end abuts against the limiting member 222. The reset member 223 is made of an elastic material. The reset member 223 can be a spring, a rubber member, or other components or materials with elastic force. To ensure that the reset member 223 generates an elastic force in the vertical direction, a guiding member can also be provided at the bottom of the mounting groove 2211 to limit the direction of elastic deformation of the reset member 223 in the vertical direction; when the n limiting members 222 are pressed down by the battery cell 3 in the vertical direction to the second position, the reset member 223 is pushed down and compressed by the n limiting members 222; there is a space in the mounting groove 2211 for the reset member 223 to stretch and recover. After the battery cell 3 and the welding tape 4 are separated from the alignment assembly 22, the reset member 223 lifts the n limiting members 222 from the second position to the first position in the vertical direction by its own elastic force.

[0088] In some embodiments, referring to Figure 7 (b), the inner wall of the notch of the limiting groove 2221 is in a slope shape in the second direction. Combining Figure 7 as shown, it is easier for the welding tape to fall into the bottom of the limiting groove 2221 when it lands on the sloped notch.

[0089] In some embodiments, the n limiting members 222 are integrally formed, that is, the n limiting members 222 in the same row are a whole. The number of the reset members 223 has nothing to do with the number of the limiting members 222. The reset member 223 only needs to ensure the overall balanced and stable lifting and lowering of the n limiting members 222.

[0090] In some embodiments, the n limiting members 222 are independent of each other, that is, the n limiting members 222 in the same row are n split structures, and the reset members 223 are configured as n. The n reset members 223 are arranged in one-to-one correspondence with the n limiting members 222, and each reset member 223 is configured to drive the corresponding limiting member 222 to the first position. The n limiting members 222 arranged along the second direction being independent of each other can ensure that the limiting members 222 in the same row are independently driven to lift and lower, thereby avoiding the mutual influence among the limiting members 222 and reducing the accuracy of welding tape position alignment. Specifically, when implemented, the n limiting members 222 arranged along the first direction are not only independent of each other when being pressed down by the battery cell, but also each limiting member 222 is independently driven by the corresponding reset member 223 to reset to the first position, that is, the reset process is also independent of each other, so as to avoid the mutual influence among the limiting members 222 and reduce the accuracy of welding tape position alignment.

[0091] The above has introduced the alignment assembly 22 provided by the embodiments of the present application in detail with reference to the accompanying drawings. Next, in combination with Figures 5 to 9 , the carrying module 2 provided by the embodiments of the present application will be further introduced.

[0092] Referring toFigure 5 As shown, the embodiment of the present application also provides a supporting module 2, the supporting module 2 includes a supporting body 21 and at least two regular components 22, the regular components 22 are arranged on the supporting body 21 along a first direction and are spaced from each other, each regular component 22 has a row of limit members 222 (each row has n limit members 222), and the support 221 and the supporting body 21 are an integral structure, the upper surface of the regular component 22 is flush with the upper surface of the supporting body 21 to facilitate the connection between the welding strip 4 and the battery cell 3, and the i-th limit groove 2221 of each regular component 22 along the second direction jointly defines a welding strip 4, so as to regularize the position of the welding strip 4 laid on the supporting module 2, so that the position of the carried welding strip 4 is accurate, thereby ensuring that each welding strip 4 is located at a preset position, reducing the probability of whitening of the battery cell grid line during the string operation, thereby reducing the defective rate of battery string welding and improving the string welding quality of the battery string.

[0093] It should be noted that Figures 5 to 9 The main figure shows the supporting module 2 when the support 221 and the supporting body 21 are an integrated structure. However, in the specific implementation, in order to facilitate maintenance and replacement of components, the support 221 and the supporting body 21 can also adopt a split structure, that is, the support 221 and the supporting body 21 are independent of each other, and the support 221, the limiter 222 and the reset member 223 are assembled to form a regular component 22, and the support 221 and the supporting body 21 are connected and assembled to form the supporting module 2.

[0094] As for the above-mentioned carrier module 2, in some embodiments, a plurality of columns of receiving grooves 211 are further formed on the upper surface of the carrier body 21, each column includes a plurality of receiving grooves 211 arranged at intervals along the first direction, and the plurality of receiving grooves 211 in adjacent columns are arranged along the second direction, and the receiving grooves 211 in the same column extend along the first direction and are collinear, each column of receiving grooves 211 corresponds to a welding strip 4 extending along the first direction, and the i-th limiting groove 2221 of each regular component 22 arranged along the second direction is located between two adjacent receiving grooves 211 in the i-th column of receiving grooves 211, and an anti-sticking strip made of Teflon material is laid in the receiving groove 211, and the upper surface of the anti-sticking strip is flush with the upper surface of the carrier body 21, and the anti-sticking strip is configured to carry the welding strip 4 extending along the first direction. After the soldering tape 4 falls into the limiting groove 2221 of each regular component 22 of the supporting module 2 along the first direction, the part of the soldering tape 4 not in the limiting groove 2221 will be supported by the anti-sticking adhesive strip in a row of receiving grooves 211. The anti-sticking adhesive strip made of Teflon material laid in the receiving groove 211 helps to avoid solder sticking during welding.

[0095] In some examples, for the carrier module 2 as described above, the carrier module 2 further includes an adsorption assembly. The adsorption assembly includes a plurality of adsorption heads 212 disposed on the carrier body 21, and a negative pressure device communicated with the adsorption heads 212. The adsorption heads 212 adsorb the battery cells under the action of the negative pressure device; the adsorption heads 212 are lower than the upper surface of the carrier body 21, the adsorption heads 212 are distributed in rows along the second direction, and at least one row of adsorption heads 212 is distributed between two adjacent alignment assemblies 22, and each row includes a plurality of adsorption heads 212 to improve the adsorption capacity for the battery cells. The cooperation of a plurality of adsorption heads 212 and the negative pressure device can be adopted to ensure the stability of the positions of the battery cells and the solder tapes 4. The plurality of adsorption heads 212 increase the coverage area of the negative pressure adsorption, thereby improving the stability and reliability of the adsorption of the adsorption assembly. During specific implementation, the negative pressure device can be communicated with the adsorption heads 212 through an inflation block. The inflation block is located on an end face of the carrier body away from the alignment assembly 22. An air path is provided inside the inflation block, and the negative pressure device is communicated with the adsorption heads 212 through this air path to provide the adsorption force.

[0096] In some examples, the carrier module 2 as described above further includes a heating assembly 213. The heating assembly 213 is located inside the carrier body 21, and the heating assembly 213 is used to heat the carrier body 21 and the battery cells 3 and solder tapes 4 carried thereon. The heating assembly 213 is adopted to realize the heating of the battery cell group and the solder tape group carried by the carrier body 21, which is helpful for implementing thermal curing. Specifically, the heating assembly 213 includes a thermocouple and an electric heating tube. One end of the electric heating tube is fixed inside the carrier module 2, and the other end is connected to a power supply for power supply and heating. One end of the thermocouple is also fixed inside the carrier module 2 and is used to measure the heating temperature to ensure the accuracy of the heating effect.

[0097] In some embodiments, such as Figure 5 and Figure 9As shown in the figure, the carrier module 2 further includes two sets of tilting components 23, which are respectively arranged at both ends of the carrier body 21 along the second direction. Each set of tilting components 23 includes a connecting plate 231, a fixing part 232, and a tilting plate 233, where: a connecting plate 231 is configured at each end of the carrier body 21. Each connecting plate 231 extends along the first direction, and each connecting plate 231 is fixedly connected to the limiting members 222 of at least two regularizing components 22. The n limiting members 222 on each regularizing component 22 are integrally arranged. In specific implementation, the structural form is not limited to this. As long as the connecting plate 231 can drive the n limiting members on the regularizing component 22 to perform a lifting action synchronously. Exemplarily, the n limiting members 222 on each regularizing component 22 can also be connected to the connecting plate 231 through an associated structure, so that the n limiting members 222 on the same regularizing component 22 are synchronously driven; in addition, a fixing part 232 is installed at each end of the carrier body 21. Each tilting plate 233 is rotatably installed on the corresponding fixing part 232 at the corresponding end of the carrier body 21. The first end of the tilting plate 233 abuts against the lower surface of the connecting plate 231. When the second end of the tilting plate 233 is driven, the tilting plate 233 rotates so that the first end of the tilting plate 233 applies an external force to the connecting plate 231, and the limiting members 222 connected to the connecting plate 231 are thus driven, so that the limiting members 222 on the regularizing component 22 are pushed up to the first position by the external force.

[0098] The method of configuring such tilting components 23 at both ends of the carrier body 21 facilitates driving one end of the tilting plate 233 to apply an external force to the limiting member 222 at the other end, thereby lifting the limiting member 222 connected to the tilting plate 233 upward to the first position, and allowing the solder tape 4 to fall in the first position state. The tilting component 23 helps to prevent the solder tape 4 from rubbing against the edge of the limiting groove 2221 and tipping over or failing to fall. In other words, when an external force acts on one end of the tilting plate 233 to stably position the limiting member 222 at the first position, when the solder tape 4 rubs against the edge of the limiting groove 2221 during the falling process, the solder tape 4 cannot press down the limiting member 222, and the solder tape 4 can only change its own position to fall into the limiting groove 2221. The tilting component 23 helps to ensure that the solder tape 4 can fall into the corresponding limiting groove 2221 more accurately.

[0099] The embodiment of the present application further provides a battery string carrier mechanism. Refer to Figure 1 and Figure 10As shown, the battery string carrying mechanism includes a base 1 and a plurality of carrying modules 2. The plurality of carrying modules 2 are arranged on the base 1 along a first direction. Each carrying module 2 is detachably mounted on the base 1. The plurality of carrying modules 2 are configured to carry a number of battery cells 3 and a number of solder tapes 4. The detachable cooperation relationship between the carrying module 2 and the base 1 in this embodiment facilitates flexible assembly and maintenance. Moreover, the battery string carrying mechanism with such a structure facilitates stably receiving the battery cells 3 and the solder tapes 4, and transporting the received battery cells and solder tapes to a fixed station for welding, ensuring the stability of the performance of the welded battery string.

[0100] It should be noted that when the carrying module 2 includes the heating component 213 as described above, in order to prevent the heating component 213 from transferring heat to other components that do not require heating, the carrying body 21 of the carrying module 2 is made of peek material or p20 material with a low thermal conductivity. In addition, the carrying module 2 is fixedly suspended on the base 1, and the carrying module is only connected to the base 1 through several connecting blocks, reducing the heat transferred from the carrying module 2 to the base 1.

[0101] The embodiment of the present application also relates to a string welding machine, which includes a solder tape transporting mechanism, a battery cell transporting mechanism, a fixing mechanism, a battery string carrying mechanism, and a conveying mechanism. Among them, the string welding machine is sequentially provided with a stringing station and a fixing station along the first direction. The driving end of the conveying mechanism is connected to the battery string carrying mechanism. The conveying mechanism is configured to drive the battery string carrying mechanism to alternately move to the stringing station and the fixing station. The solder tape transporting mechanism and the battery cell transporting mechanism are both arranged at the stringing station, the fixing mechanism is arranged at the fixing station, and the battery string carrying mechanism is configured with a plurality of carrying modules 2. The plurality of carrying modules 2 are arranged on the base 1 along the first direction. One carrying module 2 correspondingly receives one battery cell 3, and each carrying module 2 includes a carrying body 21 and at least two regularizing components 22. The regularizing components 22 are arranged on the carrying body 21 at intervals along the first direction.

[0102] Moreover, when the conveying mechanism drives the battery string carrying mechanism to move to the stringing station, the solder tape transporting mechanism is configured to lay a number of solder tapes 4 on the battery string carrying mechanism. Each solder tape 4 has a length along the first direction on the battery string carrying mechanism. The laid a number of solder tapes 4 are regularized by the regularizing components 22 located on the battery string carrying mechanism to ensure that the solder tapes 4 do not deviate in the second direction (the second direction is perpendicular to the first direction on the horizontal plane), that is, each solder tape falls into a specified position due to the limitation of the regularizing components 22. The battery cell transporting mechanism is configured to lay a number of battery cells 3 on each carrying module 2 and cover a number of solder tapes 4 to perform stringing; when the conveying mechanism drives the battery string carrying mechanism to move to the fixing station, the fixing mechanism is configured to fix the a number of solder tapes 4 and battery cells 3 that have been strung on the battery string carrying mechanism together.

[0103] Through the cooperation of the solder ribbon handling mechanism, the solar cell handling mechanism, the fixing mechanism, the solar cell string bearing mechanism and the conveying mechanism, the stringing and string soldering of the solar cell group and the solder ribbon group are realized, and the working efficiency is high; the regularizing component 22 in the solar cell string bearing mechanism can regularize each solder ribbon at the stringing station, so that each solder ribbon is located at a preset position, avoiding the exposure of the grid lines of the solar cells caused by the offset of the solder ribbon, thereby reducing the defective rate of the string soldering of the solar cell string and improving the string soldering quality of the solar cell string.

[0104] According to some examples of the fourth aspect of the present application, the bearing module 2 involved includes two sets of tilting components 23 described above. The solder ribbon handling mechanism includes a driving module and a plurality of handling components, wherein:

[0105] The number of the handling components is the same as that of the bearing module 2. The handling component includes two elastic pressing rods 5 and a handling part 6. The handling part is configured to pick up or release a plurality of solder ribbons. The two elastic pressing rods 5 are respectively located on both sides of the handling part 6 along the second direction. The distance between the two elastic pressing rods 5 matches the distance between the tilting plates 223 arranged at both ends of the bearing module 2. The lower ends of the two elastic pressing rods 5 protrude downward from the handling part 6;

[0106] The driving module is configured to drive a plurality of handling parts to move to the solder ribbon feeding place and pick up a plurality of solder ribbons. The driving module is further configured to drive a plurality of handling components to move to directly above the solar cell string bearing mechanism and descend. The two elastic pressing rods 5 of each handling component first respectively push down the second ends of the two tilting plates 223 on the bearing module 2. The second ends of the tilting plates 223 drive the first ends of the tilting plates 223 to tilt upward so that the limiting parts 222 are pushed up to the first position. Then, the plurality of handling components sequentially place the solder ribbons 4 into the corresponding limiting grooves 2221.

[0107] When the elastic pressing rods 5 arranged on both sides of the solder ribbon handling mechanism abut against the second ends of the corresponding tilting plates 233, it can ensure that the limiting parts 222 stay stably at a high position. At this time, when the solder ribbon handling mechanism places the solder ribbons again, it can avoid the situation that the solder ribbons rub against the edges of the limiting grooves 2221 or are stuck by the limiting parts 222, which is beneficial to accurately dropping the solder ribbons 4 into the limiting grooves 2221. After the accurate dropping of the solder ribbons 4 is completed, the solar cell handling mechanism transports the solar cells to the solar cell string bearing mechanism. The solar cells abut against the limiting parts 222 and push down the limiting parts 222. The limiting parts 222 descend to a position flush with the solder ribbons 4, so that the solder ribbons 4 are attached to the lower surfaces of the solar cells 3. At this time, the limiting parts 222 are in the second position.

[0108] Further, the limiting member 222 can be stably held in the lower position (the second position) under the magnetic adsorption of the second magnetic member 226. Moreover, after the welding is completed, even if the battery string is removed, the limiting member 222 remains in the lower position (the second position) until the elastic pressing rod of the solder tape handling mechanism abuts against the second end during the next solder tape handling operation, at which time the limiting member 222 will be pushed up to the position where it fits against the lower surface of the panel 224, i.e., the upper position (the first position). Such an upper position state can also be stably maintained under the magnetic adsorption of the first magnetic member 225.
