Description

Technical Field

[0001] This application relates to the field of photovoltaic production equipment, specifically a welding station and busbar welding device. Background Technology

[0002] Existing soldering stations mainly consist of a base with a mounting slot, an electromagnetic heating device located within the mounting slot, and a cover plate covering the top of the mounting slot. The electromagnetic heating device includes a magnetic core and a coil wound around the magnetic core. The busbar to be soldered rests on the cover plate, and the solder ribbons from the battery string are pressed tightly onto the busbar. When the coil is energized, it generates electromagnetic induction with the magnetic core, thereby heating and soldering the busbar and solder ribbons through the cover plate. When the magnetic core reaches its Curie temperature, the magnetic flux decreases.

[0003] To maintain stable magnetic flux in the magnetic core, it is necessary to cool the core. The existing cooling method involves placing a fan under the base to cool the base with air, and then conducting heat through the contact between the base and the magnetic core to cool the core. However, fan cooling is an indirect form of heat conduction and is not very effective. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a soldering station, the detailed technical solution of which is as follows:

[0005] A welding station includes a base, an electromagnetic heating assembly, and a cover plate, wherein:

[0006] The base is provided with a mounting cavity extending along a first direction, and the electromagnetic heating assembly is disposed in the mounting cavity. The electromagnetic heating assembly includes a plurality of magnetic cores spaced apart along the first direction and a coil wound around the magnetic cores.

[0007] The base is also provided with a first air passage, which is connected to the mounting cavity through an air inlet. Cooling gas is introduced into the mounting cavity through the first air passage and the air inlet.

[0008] The cover plate is detachably mounted on the base and covers the top opening of the mounting cavity. The cover plate is used to support the busbar to be welded.

[0009] The base or cover plate is provided with vent holes, and the mounting cavity communicates with the external space through the vent holes.

[0010] The welding station provided in this application has a first air passage in its base that communicates with the mounting cavity. Cooling gas can be introduced into the mounting cavity through the first air passage. When the cooling gas flows in the mounting cavity, it directly cools and lowers the temperature of the magnetic core, thereby improving the cooling effect on the magnetic core and ensuring that the heating temperature of the magnetic core is kept below the Curie temperature, ultimately making the magnetic flux of the magnetic core stable.

[0011] In some embodiments, the air inlet is disposed on the bottom wall or side wall of the mounting cavity, and the air outlet is disposed on the cover plate or on the bottom wall or side wall of the mounting cavity.

[0012] Several positions for the air inlet and outlet are provided, all of which ensure that the cooling gas in the first air path can flow into the mounting cavity through the air inlet, and after heat exchange with the magnetic core in the mounting cavity, it flows out of the mounting cavity through the air outlet.

[0013] In some embodiments, a plurality of air inlets are provided, and the plurality of air inlets are arranged at intervals along a first direction on a first side of the magnetic core; a plurality of air outlets are provided, and the plurality of air outlets are arranged at intervals along a first direction on a second side of the magnetic core opposite to the first side; the air outlets and air inlets are arranged alternately in the first direction.

[0014] Multiple air inlets and outlets are arranged alternately along both sides of the magnetic core, forcing the cooling gas to flow in a meandering manner along the first direction (i.e. the arrangement direction of the magnetic core), thereby extending the residence time of the cooling gas in the mounting cavity, enhancing the heat exchange efficiency between the cooling gas and the magnetic core, and improving the heat dissipation effect on the magnetic core.

[0015] In some embodiments, among two air outlets adjacent to any air inlet, the diameter of the air outlet closer to the air inlet is smaller than the diameter of the air outlet farther from the air inlet.

[0016] Setting the diameter of the outlet hole closer to the inlet hole to be smaller increases the outflow resistance at that outlet. Conversely, setting the diameter of the outlet hole farther from the inlet hole increases the outflow resistance at that outlet. This arrangement forces more of the cooling gas flowing into the mounting cavity through any inlet hole to flow towards the area farther away from that inlet hole, thus avoiding the problem of overcooling in the area near the inlet hole and undercooling in the area farther away, ultimately improving the cooling uniformity of each magnetic core in the mounting cavity.

[0017] In some embodiments, the cover plate is provided with adsorption holes arranged at intervals along a first direction; a second air passage is also provided in the base, the second air passage is connected to each adsorption hole, and the second air passage is used to evacuate air from each adsorption hole so that each adsorption hole generates an adsorption force for adsorbing the manifold.

[0018] By setting adsorption holes spaced apart along the first direction on the cover plate, the cover plate can adsorb and position the busbar, preventing the busbar from shifting or moving.

[0019] In some embodiments, the number of adsorption holes is two, and the two adsorption holes work together to adsorb one manifold.

[0020] Two adsorption holes work together to adsorb the manifold from two different locations, ensuring stable adsorption of the manifold. Furthermore, compared to having three or more adsorption holes, having two adsorption holes reduces the complexity of the adsorption gas path setup, lowers the risk of leakage after the cover plate adsorbs the manifold, and reduces power consumption.

[0021] In some embodiments, the top of a plurality of magnetic cores protrudes upward into a mounting cavity, and the cover plate is a non-metallic plate. The cover plate includes a support portion, a first connecting portion, and a second connecting portion, wherein: the support portion is disposed on the top of the plurality of magnetic cores for supporting the busbar; the first connecting portion and the second connecting portion are respectively located on both sides of the support portion along a second direction, and the first connecting portion and the second connecting portion are connected to the base; the second direction is perpendicular to the first direction.

[0022] Using a non-metallic plate as the cover plate allows the electromagnetic waves generated by the electromagnetic heating component to pass smoothly through the cover plate to heat the busbars and solder ribbons, eliminating eddy current losses. The cover plate consists of a support part, a first connecting part, and a second connecting part. On the one hand, it ensures that the cover plate can be firmly installed on the base, and on the other hand, it allows the magnetic core to specifically heat the busbars and solder ribbons supported on the support part, improving welding efficiency and reducing power consumption.

[0023] In some embodiments, the support portion is flat, the first connecting portion includes a first horizontal plate and a first vertical plate connected at right angles, and the second connecting portion includes a second horizontal plate and a second vertical plate connected at right angles; the first vertical plate and the second vertical plate are respectively connected to the support portion and integrally formed, and the first horizontal plate and the second horizontal plate are respectively fixedly installed on the base; or, the support portion is connected to the first vertical plate and integrally formed, the second vertical plate abuts against the bottom surface of the support portion, and the first horizontal plate and the second horizontal plate are respectively fixedly installed on the base.

[0024] The support portion is designed as a flat plate, and the first and second connecting portions are respectively configured as "L"-shaped structures formed by a first horizontal plate, a first vertical plate, a second horizontal plate, and a second vertical plate. This design allows the busbar to be supported horizontally on the support portion, ultimately ensuring that all solder strips on the busbar are compressed and welded to the busbar, reducing the risk of incomplete soldering. Furthermore, the first and second connecting portions can be securely mounted on the base and cover the side walls of the magnetic core extending from the mounting cavity.

[0025] By making the first vertical plate of the first connecting part and the second vertical plate of the second connecting part integrally formed with the supporting part, the disassembly and assembly of the cover plate are facilitated. Making the supporting part integrally formed with the first vertical plate of the first connecting part, and having the second vertical plate of the second connecting part abut against the bottom surface of the supporting part, reduces the manufacturing difficulty of the cover plate and better ensures the levelness of the supporting part.

[0026] In some embodiments, the soldering station further includes heat dissipation fins disposed on the bottom and / or sides of the base.

[0027] The heat dissipation fins dissipate heat from the base, enabling the base to conduct heat to the magnetic core through contact, further improving the cooling effect on the magnetic core.

[0028] In some embodiments, the soldering station further includes a housing disposed at the bottom of the base, and a power supply component and a cooling fan are disposed inside the housing. The power supply component is electrically connected to the coil of the electromagnetic heating component, and the cooling fan is used to perform air cooling on the power supply component.

[0029] By setting up a power supply component, the electromagnetic heating component is powered, while by setting up a cooling fan, the power supply component is cooled down to prevent it from overheating.

[0030] This application also provides a busbar welding device, which includes a welding support mechanism and a pressing mechanism, wherein: the welding support mechanism includes a first mounting base and n welding stations, the bases of the n welding stations are spaced apart on the first mounting base along a first direction, and the welding stations are any of the welding stations described above; the pressing mechanism is disposed above the welding support mechanism, and the pressing mechanism is used to press the welding strip at the end of the battery string downward to the busbar on the welding station; the welding station is also used to heat the pressed busbar and welding strip to weld the busbar and welding strip; wherein, n≥1.

[0031] Through the cooperation of the welding support mechanism and the clamping mechanism, the busbar welding device of this application realizes the automatic welding of the welding strip at the end of the battery string to the busbar. Attached Figure Description

[0048] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] As described in the background section, the existing method for cooling the magnetic core involves placing a fan under the base and using the fan to cool the base. The cooling of the magnetic core is achieved through heat conduction between the base and the magnetic core. However, this fan-based cooling method is an indirect form of heat conduction and is not very effective.

[0050] Therefore, this application provides a soldering station. For example... Figures 1 to 8 As shown, the welding station 10 provided in this application includes a base 1, an electromagnetic heating assembly 2, and a cover plate 3, wherein:

[0051] The base 1 is provided with a mounting cavity 4 extending along a first direction (such as the X direction). The electromagnetic heating assembly 2 is disposed in the mounting cavity 4. The electromagnetic heating assembly 2 includes a plurality of magnetic cores 21 spaced apart along the first direction and coils 22 wound around the magnetic cores 21.

[0052] The base 1 is also provided with a first air passage 5, which is connected to the mounting cavity 4 via an air inlet 6. Cooling gas is introduced into the mounting cavity 4 through the first air passage 5 and the air inlet 6.

[0053] The cover plate 3 is detachably mounted on the base 1 and covers the top opening of the mounting cavity 4. The cover plate 3 is used to support the busbar to be welded. For example, the cover plate 3 can be screwed to the base 1 by screws 14.

[0054] The base 1 or cover plate 3 is provided with an air vent 7, and the mounting cavity 4 communicates with the external space through the air vent 7.

[0055] The welding station 10 provided in this application has a first air passage 5 in its base 1 that communicates with the mounting cavity 4. Cooling gas can be introduced into the mounting cavity 4 through the first air passage 5. When the cooling gas flows in the mounting cavity 4, it directly cools down the magnetic core 21, thereby improving the cooling effect on the magnetic core 21 and ensuring that the heating temperature of the magnetic core 21 is kept below the Curie temperature, so that the magnetic flux of the magnetic core 21 remains stable.

[0056] Optionally, one end of the first air passage 5 is closed, while the other end of the first air passage 5 is connected to an external compressed air source via an air pipe, and the compressed air source introduces cooling gas into the first air passage 5. The cooling gas can be compressed air at room temperature (e.g., 25 degrees Celsius), or compressed air that has been cooled to a temperature lower than room temperature.

[0057] The air inlet 6 can be located on the bottom wall or the side wall of the mounting cavity 4, as long as it can ensure that the cooling gas in the first air passage 5 can flow into the mounting cavity 4. The air outlet 7 can be located on the cover plate 3, or on the bottom or side wall of the mounting cavity 4, as long as it can ensure that the cooling gas in the mounting cavity 4 that has completed heat exchange with the magnetic core 21 can flow out of the mounting cavity 4.

[0058] like Figure 5 As shown, optionally, multiple air inlets 6 (e.g., 2, 3, 4, 5 or more) are arranged at intervals along a first direction on a first side (e.g., the right side) of the magnetic core 21. Multiple air outlets 7 (e.g., 2, 3, 4, 5 or more) are arranged at intervals along a first direction on a second side (e.g., the left side) of the magnetic core 21 opposite to the first side, and the air outlets 7 and air inlets 6 are arranged alternately in the first direction.

[0059] Multiple air inlets 6 and multiple air outlets 7 are arranged alternately along both sides of the magnetic core 21, which can force the cooling gas in the mounting cavity 4 to flow in a meandering manner along the first direction (i.e. the arrangement direction of the magnetic core 21), thereby prolonging the residence time of the cooling gas in the mounting cavity 4, thereby enhancing the heat exchange efficiency between the cooling gas and the magnetic core 21 and improving the heat dissipation effect on the magnetic core 21.

[0060] Optionally, among the two air outlets 7 adjacent to any one of the air inlets 6, the diameter of the air outlet 7 closer to the air inlet 6 is smaller than the diameter of the air outlet 7 farther from the air inlet 6.

[0061] Setting the diameter of the outlet 7 closer to the inlet 6 to be smaller increases the outflow resistance at that outlet 7. Conversely, setting the diameter of the outlet 7 farther from the inlet 6 to be larger reduces the outflow resistance at that outlet 7. This arrangement forces the cooling gas flowing into the mounting cavity 4 through any inlet 6 to flow more towards the area farther from the inlet 6, thus solving the problem of overcooling in the area close to the inlet 6 and insufficient cooling in the area far from the inlet 6, ultimately improving the cooling uniformity of each magnetic core 21 within the mounting cavity 4.

[0062] Since multiple air inlets 6 are arranged at intervals along the first direction on the first side of the magnetic core 21, in order to improve the uniformity of air intake of each air inlet 6, the first air passage 5 is arranged parallel to the mounting cavity 4, that is, the first air passage 5 also extends along the first direction.

[0063] like Figures 1 to 3 As shown, optionally, the cover plate 3 is provided with adsorption holes 8 arranged at intervals along the first direction. The base 1 is also provided with a second air passage 9, which is connected to each adsorption hole 8. The second air passage 9 is used to evacuate air from each adsorption hole 8 so that each adsorption hole 8 generates an adsorption force for adsorbing the manifold.

[0064] It can be seen that by providing adsorption holes 8 arranged at intervals along the first direction on the cover plate 3, the cover plate 3 can adsorb the busbars placed on it and extending along the first direction, thus preventing the busbars from shifting and affecting the welding quality.

[0065] like Figure 1 and Figure 2 As shown, there are two adsorption pores 8, which work together to adsorb one manifold. By using two adsorption pores 8 to adsorb the manifold from two different positions, the adsorption stability of the manifold can be improved.

[0066] Of course, the number of adsorption holes 8 can also be 3, 4 or more. Compared with setting 3 or more adsorption holes 8, setting 2 adsorption holes 8 is particularly suitable for situations where the manifold is uneven. By implementing two-point adsorption on the manifold, the manifold can be better leveled. However, with multi-point adsorption, the unevenness of the manifold may cause gaps between a certain adsorption hole and the manifold, resulting in air leakage, which in turn affects the adsorption force of the remaining adsorption holes and affects the final adsorption effect of the manifold.

[0067] like Figures 1 to 3 As shown, optionally, the tops of several magnetic cores 21 protrude upwards from the mounting cavity 4. The cover plate 3 is a non-metallic plate, and the cover plate 3 includes a supporting part 31, a first connecting part 32, and a second connecting part 33, wherein: the supporting part 31 is disposed on the top of several magnetic cores 21 for supporting the busbar. The first connecting part 32 and the second connecting part 33 are respectively located on both sides of the supporting part 31 along a second direction (such as the Y direction), and the first connecting part 32 and the second connecting part 33 are connected to the base 1, the second direction being perpendicular to the first direction.

[0068] Using a non-metallic plate as the cover plate 3 allows the electromagnetic waves generated by the electromagnetic heating component 2 to pass smoothly through the cover plate 3 for heating and welding of the busbar and solder strip, while eliminating eddy current losses and reducing power consumption. The non-metallic plate can be, for example, a ceramic plate, a mica plate, or a carbon fiber plate. These cover plates 3 have smooth bearing surfaces, which can prevent the cover plate 3 from sticking to the busbar during the welding process.

[0069] The cover plate 3 is composed of a support portion 31, a first connecting portion 32, and a second connecting portion 33. On the one hand, it ensures that the cover plate 3 can be firmly installed on the base 1, and on the other hand, it enables the magnetic core 21 to specifically heat the busbar and solder strip supported on the support portion 31, thereby improving welding efficiency and reducing power consumption.

[0070] Optionally, the supporting part 31 is flat, the first connecting part 32 includes a first horizontal plate and a first vertical plate connected at right angles, and the second connecting part 33 includes a second horizontal plate and a second vertical plate connected at right angles.

[0071] The support portion 31 is configured as a flat plate, and the first connecting portion 32 and the second connecting portion 33 are respectively configured as "L"-shaped structures composed of a first horizontal plate, a first vertical plate, a second horizontal plate, and a second vertical plate. This allows the busbar to be supported horizontally on the support portion, ultimately ensuring that all solder strips on the busbar are compressed and welded to the busbar, reducing the risk of incomplete soldering. Furthermore, both the first and second connecting portions are stably fixed to the base, covering the sidewalls of the magnetic core extending from the mounting cavity.

[0072] To facilitate the assembly and disassembly of the cover plate 3, in one optional embodiment, the first vertical plate of the first connecting part 32 and the second vertical plate of the second connecting part 33 are respectively connected to the bearing part 31 and integrally formed, and the first horizontal plate and the second horizontal plate are respectively fixedly installed on the base 1.

[0073] To facilitate the processing and forming of the cover plate 3, in another optional embodiment, the supporting part 31 is connected to and integrally formed with the first vertical plate of the first connecting part 32, and the second vertical plate of the second connecting part 33 abuts against the bottom surface of the supporting part 31. The first horizontal plate and the second horizontal plate are respectively fixedly installed on the base 1. That is to say, the cover plate 3 is a split structure composed of two parts, which can reduce the manufacturing difficulty of the cover plate 3 and make it easier to ensure the levelness of the supporting part 31.

[0074] Optional, such as Figure 4 As shown, the soldering station 10 in this embodiment further includes heat dissipation fins 11 disposed on the bottom and / or side of the base 1. The heat dissipation fins 11 dissipate heat from the base 1, enabling the base 1 to perform contact-type thermal conduction cooling of the magnetic core 21, further improving the cooling effect on the magnetic core 21.

[0075] Optional, such as Figure 1 As shown, the soldering station 10 in this embodiment of the application also includes a cover 12 disposed at the bottom of the base 1. The cover 12 is provided with a power supply component and a cooling fan 13. The power supply component is electrically connected to the coil 22 of the electromagnetic heating component 2, and the cooling fan 13 is used to perform air cooling on the power supply component.

[0076] By setting up a power supply component, power is supplied to the electromagnetic heating component 2, while by setting up a cooling fan 13, the power supply component is cooled down, preventing it from being damaged by heat. Optionally, the power supply component includes a transformer and a capacitor, with the capacitor connected to the coil 22 and the transformer supplying power to the capacitor.

[0077] This application also provides a busbar welding device. For example... Figure 9 As shown, the busbar welding device includes a welding bearing mechanism and a clamping mechanism 30, wherein:

[0078] The welding support mechanism includes a first mounting base 20 and n welding stations 10. The bases 1 of the n welding stations 10 are installed at intervals on the first mounting base 20 along a first direction (such as the X direction). The welding stations 10 are the welding stations 10 provided in any of the above embodiments, wherein n≥1.

[0079] The clamping mechanism 30 is located above the welding support mechanism. The clamping mechanism 20 is used to press the welding strip at the end of the battery string downwards onto the busbar on the welding station 10. The welding station is also used to heat the clamped busbar and welding strip to weld the busbar and welding strip.

[0080] Where n≥1.

[0081] As can be seen, through the cooperation of the welding support mechanism and the clamping mechanism 30, the busbar welding device of this application realizes the automatic welding of the long welding strip at the end of the battery string to the busbar.

[0082] Figure 9 In the illustrated embodiment, three welding stations 10 are provided, i.e., n=3. In other embodiments, one, two, four, or other numbers of welding stations 10 may be provided as needed. In the case of two or more welding stations 10, during the welding process, the busbar to be welded can be supported on one welding station 10 or simultaneously on two or more welding stations 10.

[0083] like Figure 9 As shown, optionally, the clamping mechanism 30 includes a lifting drive 301, a second mounting base 302, and a pressure head 303. The second mounting base 302 is connected to the drive end of the lifting drive 301, which drives the second mounting base 302 to move up and down. The pressure head 303 is mounted on the second mounting base 302. When the lifting drive 301 drives the second mounting base 302 to descend toward the soldering station 10, the pressure head 303 presses the solder strip at the end of the battery string onto the busbar located on the soldering station 10.

[0084] like Figure 10 As shown, optionally, the clamping mechanism 30 includes a plurality of (here, "a plurality of" means two or more, such as five in the figure) pressure heads 303, which are spaced apart on the second mounting base 302 along a first direction, and each pressure head 303 is configured to float up and down relative to the second mounting base 302. For example, each pressure head 303 is connected to the bottom of the second mounting base 302 via a spring connector that can extend and retract up and down.

[0085] Thus, when the lifting drive 301 drives the second mounting base 302 to descend toward the welding station 10, the pressure head 303 that first contacts the welding strip can adaptively float upward, allowing the second mounting base 302 to continue descending until all the pressure heads 303 press the welding strip below them onto the busbar, thereby pressing all the welding strips on the busbar onto the busbar and avoiding incomplete welding.

[0086] Of course, such as Figure 11 As shown, the clamping mechanism 30 may also include only a strip-shaped clamping head 303 extending along the first direction. When the lifting drive 301 drives the second mounting base 302 to descend toward the welding station 10, the clamping head 303 uniformly clamps all the busbars below it onto the welding station 10.

Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within its protection scope. The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Without contradiction, some optional components in one embodiment can also be used in another embodiment, and some preferred structures of the same component in one embodiment are also applicable to another embodiment.
