[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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 utility model based on the specific circumstances.

[0024] Example like Figs. 1-3 As shown, the solder strip preparation mold proposed in the embodiment of this utility model includes: The support frame 1 and the pouring mechanism movably disposed on the support frame 1, wherein the pouring mechanism contains a pouring solution; Mold block 2 is movably disposed within the support frame 1. The first side of the mold block 2 facing away from the ground is recessed in the direction of the ground to form a mold groove 3. The two opposite ends of the mold groove 3 are far apart from each other and extend outward from the first side along the extension direction of the mold block 2. The mold groove 3 is located below the output end of the casting mechanism. An electric heating component is laid at the bottom of the mold groove for heating the welding strip.

[0025] Specifically, the support frame 1 can provide support and fixation. The support frame 1 has an internal space for accommodating the mold block 2 and the casting mechanism. The surface of the support frame 1 that is in contact with the ground is the bottom surface, the side of the support frame 1 opposite to the bottom surface is the top surface, the side of the support frame 1 that extends in the same direction as the mold block 2 is the first side surface, and the side of the support frame 1 opposite to the first side surface is the second side surface. The two opposite sides of the support frame 1 located between the bottom surface, the top surface, the first side surface, and the second side surface are the third side surface 4 and the fourth side surface 5, respectively. Both the third side surface 4 and the fourth side surface 5 have openings. The side of the mold block 2 opposite to the third side surface 4 extends out of the accommodating space through the opening of the third side surface 4, and the side of the mold block 2 opposite to the fourth side surface 5 extends out of the accommodating space through the opening of the fourth side surface 5.

[0026] The mold block 2 has a mold groove 3, in which solder ribbon is placed. The solder ribbon is photovoltaic solder ribbon, also known as tin-plated copper ribbon or tin-coated copper ribbon, and is divided into busbars and interconnecting strips. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity and concentrating. The mold block 2 is movably set in the support frame 1. This structural design facilitates the later maintenance of the mold block 2 by technicians.

[0027] The casting mechanism is used to pour the solution into the mold groove 3 to complete the preparation process of the solder strip, facilitating the combination of the prepared solder strip with the solar cell body and the fabrication of the solar panel. The mold groove 3 is located below the output end of the casting mechanism, and an electric heating element is laid at the bottom of the mold groove, with the temperature adjustable from room temperature (25℃) to 350℃; preferably, other heating methods can also be used to heat the solder strip. This structural design allows the solder strip preparation process to be completed simultaneously as the casting mechanism pours the solution into the mold groove 3 along its extension direction, facilitating the combination of the prepared solder strip with the solar cell body and the fabrication of the solar panel.

[0028] This embodiment of the invention employs a single-sided coating, giving the solder strip a dual function: improving the reflectivity of the front light-receiving surface and enhancing the bonding strength of the back surface. This can increase the overall power of the solar module and simplify the stringing process.

[0029] In specific implementation, the casting solution is a conductive coating and an anti-oxidation coating.

[0030] Specifically, the anti-oxidation coating improves both the oxidation resistance of the solder ribbon and the conductivity of the prepared solder ribbon. The conductive coating is used to connect with the fine grid of the solar cell body.

[0031] In this application, the casting mechanism first pours anti-oxidation coating into the mold groove 3 containing the welding strip along the direction from the third side 4 or the fourth side 5 to the fourth side 5 or the third side 4, so that the anti-oxidation coating wraps the welding strip in the mold groove 3. At this time, the welding strip wrapped with anti-oxidation coating does not completely fill the entire mold groove 3. The remaining unfilled part in the mold groove 3 is the contact side between the welding strip wrapped with anti-oxidation coating and the fine grid of the battery cell body. Therefore, the casting mechanism then pours conductive coating into the unfilled mold groove 3 from the direction from the fourth side 5 or the third side 4 to the third side 4 or the fourth side 5. This structural design can not only complete the welding strip preparation process, but also ensure the connection between the welding strip and the battery cell body, while significantly saving material costs and avoiding excessive material waste.

[0032] In specific implementations, the conductive coating is a thermoplastic conductive adhesive; the anti-oxidation coating can be made of silver, tin, aluminum, nickel, tin alloy, aluminum alloy, silver-tin alloy, tin-lead alloy, or tin-lead-bismuth alloy materials.

[0033] Specifically, thermoplastic conductive adhesives offer excellent static conductivity, acting as a protective energy absorption layer. Thermoplastic conductive adhesives are simple to process (the preparation and processing of thermoplastic conductive adhesives are relatively simple, easily automated, and reduce production costs), reusable (the base resin molecules of thermoplastic conductive adhesives have long molecular chains and few branches, resulting in good fluidity during high-temperature curing, thus allowing for reuse), and also possess good heat resistance (the good fluidity during high-temperature curing allows them to withstand higher operating temperatures and exhibits good heat resistance).

[0034] like Figs. 1-3 As shown, in a specific implementation, the cross-sectional shape of the mold groove 3 along the direction perpendicular to the ground is one of a triangle, a quadrilateral, or a pentagon.

[0035] Specifically, the existing photovoltaic industry lacks equipment for preparing polygonal solder strips. Most of the solder strip equipment used is for preparing solder strips with a circular radial cross-section. Although this equipment can prepare solder strips, the contact area between the circular radial cross-section solder strip and the fine grid of the solar cell is small, resulting in poor conductivity compared to solder strips with a polygonal radial cross-section. Therefore, this application provides a preparation device for solder strips with a polygonal radial cross-section, which can not only improve the preparation effect of solder strips with a polygonal radial cross-section, but also solve the technical problem of the lack of polygonal solder strip preparation equipment in the prior art.

[0036] In this application, the mold groove 3 of mold block 2 can have a triangular cross-sectional shape along the direction perpendicular to the ground, allowing a technician to prepare a weld strip with a triangular radial cross-sectional shape. If the mold groove 3 of mold block 2 has a quadrilateral cross-sectional shape along the direction perpendicular to the ground, a technician can prepare a weld strip with a quadrilateral radial cross-sectional shape. If the mold groove 3 of mold block 2 has a pentagonal cross-sectional shape along the direction perpendicular to the ground, a technician can prepare a weld strip with a pentagonal radial cross-sectional shape. Therefore, a technician can prepare mold block 2 according to actual needs and use the prepared mold block 2 to prepare the required radial cross-sectional shape of the weld strip.

[0037] In specific implementation, the mold block 2 and the support frame 1 are connected in a detachable manner.

[0038] Specifically, this structural design allows the device to be equipped with multiple mold blocks 2. For example, there are three mold blocks 2. The mold groove 3 of the first mold block 2 has a triangular cross-sectional shape along the direction perpendicular to the ground. If the technician wants to prepare weld strips with a radial cross-sectional shape of triangle, the mold block 2 with a triangular cross-sectional shape along the direction perpendicular to the ground can be fixed in the support frame 1 with bolts and nuts, and the process of preparing weld strips with a radial cross-sectional shape of triangle can be carried out. The mold groove 3 of the second mold block 2 has a quadrilateral cross-sectional shape along the direction perpendicular to the ground. If the technician wants to prepare weld strips with a quadrilateral cross-sectional shape along the direction perpendicular to the ground, the mold block 2 can be fixed in the support frame 1 with bolts and nuts. The quadrilateral mold block 2 is fixed inside the support frame 1 and a process for preparing a weld strip with a radial cross-sectional shape of quadrilateral is performed. The mold groove 3 of the third mold block 2 has a pentagonal cross-sectional shape along the direction perpendicular to the ground. If the technician wants to prepare a weld strip with a radial cross-sectional shape of pentagon, the mold block 2 with a pentagonal cross-sectional shape along the direction perpendicular to the ground can be fixed inside the support frame 1 by bolts and nuts, and a process for preparing a weld strip with a radial cross-sectional shape of pentagon can be performed. It can be seen that the technician can select the appropriate mold block 2 according to the actual needs and install it inside the support frame 1 to prepare the radial cross-sectional shape of the required weld strip. Mold blocks 2 that are different from the required ones can be disassembled and removed from the support frame 1.

[0039] It should be noted that the mold block 2 and the support frame 1 can be detachably connected by a plug-in method, such as a plug and a slot, or by a snap-fit ​​method, such as a protrusion and a buckle. The disassembled mold block 2 can be moved manually or by equipment, such as a crane or transport vehicle. The detachable connection between the mold block 2 and the support frame 1 also facilitates later maintenance of the device.

[0040] In a specific implementation, a slide is provided on the side of the support frame 1 facing away from the casting mechanism, and the extension direction of the slide is the same as the extension direction of the mold block 2. The mold block 2 has a sliding groove on the side facing away from the mold groove 3, which is in movable connection with the slide rail. The support frame 1 is equipped with a telescopic mechanism, and the telescopic end of the telescopic mechanism is detachably connected to the mold block 2.

[0041] Specifically, if the mold groove 3 in the support frame 1 has a triangular cross-sectional shape along the direction perpendicular to the ground, and the technician wants to prepare a welding strip with a quadrilateral radial cross-sectional shape, the telescopic mechanism, in conjunction with the slide and the slide rail, can move the mold groove 3 with a triangular cross-sectional shape along the direction perpendicular to the ground from the opening on the third side 4 or the fourth side 5 to the outside of the receiving space. At this time, the technician separates the mold groove 3 with a triangular cross-sectional shape along the direction perpendicular to the ground from the telescopic mechanism, moves the disassembled mold groove 3 with a triangular cross-sectional shape along the direction perpendicular to the ground to the storage area, and then transports the mold groove 3 with a quadrilateral cross-sectional shape along the direction perpendicular to the ground from the storage area to the vicinity of the telescopic end of the telescopic mechanism, so that the mold groove 3 with a quadrilateral cross-sectional shape along the direction perpendicular to the ground is connected to the telescopic end of the telescopic mechanism. The telescopic mechanism, in conjunction with the slide and the slide rail, can move the mold groove 3 with a quadrilateral cross-sectional shape along the direction perpendicular to the ground from the opening on the third side 4 or the fourth side 5 to the inside of the receiving space.

[0042] The telescopic mechanism can drive the mold block 2 to move back and forth within the support frame 1 through the slide and the slide rail. On the one hand, it can cooperate with the casting mechanism to complete the preparation process of the welding strip. On the other hand, through the telescopic end of the telescopic mechanism and the detachable connection with the mold block 2, the technical effect of automatically handling the mold block 2 can be achieved, avoiding the need for the useless mold block 2 to be transported to the outside of the support frame 1 by manual handling, thus achieving the effect of saving time and effort.

[0043] In a specific implementation, the telescopic mechanism includes: A hydraulic telescopic rod, the cylinder end of which is connected to the support frame 1, and the telescopic end of which is detachably connected to the mold block 2 by bolts.

[0044] Specifically, hydraulic telescopic rods are existing technologies that can be obtained through procurement.

[0045] In a specific implementation, the support frame 1 is provided with a slide table, and the slider of the slide table is connected to the casting mechanism; The extension direction of the slide rod of the slide table is the same as the extension direction of the mold block 2.

[0046] Specifically, this structural design facilitates the reciprocating movement of the casting mechanism between the third side 4 and the fourth side 5, enabling the casting mechanism to perform the casting process on the weld strip within the mold groove 3. The slide table is existing technology and can be purchased; the specific connection method of the slide table is known to technical personnel and will not be elaborated here.

[0047] In a specific implementation, the support frame 1 is provided with a guide rod, the guide rod is located above the mold block 2, and the extension direction of the guide rod is the same as the extension direction of the mold block 2; A movable block is provided on the guide rod, the movable block is slidably connected to the guide rod, and the movable block is connected to the pouring mechanism; The support frame 1 is equipped with a telescopic cylinder, the output end of which is connected to the moving block, and the travel direction of the output end of the telescopic cylinder is the same as the extension direction of the guide rod.

[0048] Specifically, this application provides another implementation method for the pouring mechanism to reciprocate between the third side 4 and the fourth side 5, that is, the telescopic cylinder is used as the power source, the pouring mechanism is slidably connected to the support frame 1 through the guide rod and the moving block, the telescopic cylinder drives the moving block, so that the moving block drives the pouring mechanism to reciprocate on the guide rod, thereby achieving the effect of the pouring mechanism reciprocating between the third side 4 and the fourth side 5.

[0049] In specific implementation, the pouring mechanism includes: A first liquid storage tank and a second liquid storage tank are connected sequentially along the extension direction of the mold block 2. The first liquid storage tank is hollow inside and contains a thermoplastic conductive adhesive solution. A first liquid inlet communicating with the interior is provided on the top surface of the first liquid storage tank away from the ground, and a first solenoid valve is provided at the first liquid inlet. A first liquid outlet communicating with the interior is provided on the bottom surface of the first liquid storage tank opposite to the ground, and a second solenoid valve is provided at the first liquid outlet. The second liquid storage tank is hollow inside and contains a silver solution. A second liquid inlet communicating with the interior is provided on the top surface of the second liquid storage tank away from the ground, and a third solenoid valve is provided at the second liquid inlet. A second liquid outlet communicating with the interior is provided on the bottom surface of the second liquid storage tank opposite to the ground, and a fourth solenoid valve is provided at the second liquid outlet.

[0050] Specifically, the first storage tank is used to store thermoplastic conductive adhesive solution, and the second storage tank is used to store silver solution. The first inlet is used to replenish the first storage tank with thermoplastic conductive adhesive solution, and the second inlet is used to replenish the second storage tank with silver solution. The first outlet is used to pour thermoplastic conductive adhesive solution into the mold groove 3, and the second outlet is used to pour silver solution into the mold groove 3. The first and second storage tanks can be connected in a detachable manner or in a fixed manner, such as by snap-fit, plug-in, welding, bonding, or bolting. After connection, the first and second storage tanks can be detachably connected to the slider of the slide table or to the moving block.

[0051] The first solenoid valve is used to control whether the first liquid inlet is open, the second solenoid valve is used to control whether the first liquid outlet is open, the third solenoid valve is used to control whether the second liquid inlet is open, and the fourth solenoid valve is used to control whether the second liquid outlet is open.
