DETAILED DESCRIPTION

[0043] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application.

[0044] In the description of this application, it should be understood that the terms "height", "thickness", "up", "down", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting this application. In the description of this application, "plurality" means two or more, and at least one means one, two, or more than two, unless otherwise clearly and specifically defined.

[0045] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked X indicates the first direction of the welding cooling device, the arrow marked Y indicates the second direction of the welding cooling device, and the arrow marked Z indicates the third direction of the welding cooling device. The first direction, the second direction and the third direction are introduced to more clearly express the structure and relative position relationship of each component in the welding cooling device. In actual applications, the first direction, the second direction and the third direction may change according to the different placement methods of the welding cooling device.

[0046] In related technologies, the battery protection board includes a soft board, a hard board and a nickel sheet. Among them, the hard board is also called a PCB board, and the soft board is also called an FPC board. The soft board and the nickel sheet are both welded to the hard board and distributed on both sides of the hard board. Since the nickel sheet and the soft board pads may completely overlap or partially overlap, when the board thickness is thin, welding the nickel sheet first and then welding the soft board may cause secondary tin melting at the nickel sheet pad, which makes the pulling force of the nickel sheet fail to meet the design standard, affecting the electrical performance of the battery.

[0047] Please combine Figure 1 、 Figure 2 and Figure 3 The welding cooling device of the embodiment of the present application is used to cool the battery protection plate. The welding cooling device includes a base 1, a cooling component 2 and a clamping component 3. The cooling component 2 is arranged on the base 1, and the cooling component 2 includes a heat conductive block 21.

[0048] The clamping assembly 3 is used to be set on the base 1. The clamping assembly 3 includes a clamping area 311 and a hollow groove 312 connected to the clamping area 311. The heat-conducting block 21 is arranged in the hollow groove 312. The clamping assembly 3 is used to clamp the battery protection plate 6 in the clamping area 311 so that the battery protection plate 6 is in contact with the heat-conducting block 21. The clamping area 311 is similar in shape to the battery protection plate 6. On the one hand, it has the function of accommodating the battery protection plate 6. On the other hand, it can position the battery protection plate 6 to prevent the position of the battery protection plate 6 from shifting. It can be understood that the clamping assembly 3, as a component of the cooling device for welding, has a structure for the welding gun to weld the battery protection plate 6 while keeping the battery protection plate 6 clamped.

[0049] The clamping assembly 3 is supported as a whole on the base 1, and the heat-conducting block 21 is connected to the side of the base 1 facing the clamping assembly 3. The heat-conducting block 21 is inserted into the hollow groove 312 and contacts the battery protection board 6. When the soft board is welded, the heat-conducting block 21 is placed in the hollow groove 312 connected to the clamping area 311, so that the heat-conducting block 21 can be in direct contact with the battery protection board 6. The heat generated during the welding process of the battery protection board 6 located in the clamping area 311 is transferred to the heat-conducting block 21, and then the heat is discharged by the heat-conducting block 21, thereby achieving direct cooling of the contact position between the battery protection board 6 and the heat-conducting block 21, so that the cooling effect of the battery protection board 6 is improved, thereby reducing the possibility of tin melting in the welded parts of the battery protection board 6, and is conducive to increasing the pull-out force and electrical performance of each component after the battery protection board 6 is welded. Specifically, the clamping component 3 is supported as a whole on the base 1, the heat-conducting block 21 is in conflict with the nickel sheet 61, and the heat generated by the battery protection plate 6 during the welding process is transferred to the nickel sheet 61, and then transferred to the heat-conducting block 21 by the nickel sheet 61. On the one hand, the heat-conducting block 21 absorbs and conducts the heat through the cooling component 2, and on the other hand, it dissipates part of the heat through heat exchange with the air, thereby achieving direct cooling of the nickel sheet 61 to prevent the welding position of the nickel sheet 61 from being affected by heat and causing secondary tin melting, thereby ensuring the pulling force of the nickel sheet 61 welding, and facilitating the normal operation of the battery electrical performance.

[0050] Please combine Figure 2 and Figure 3 In some embodiments, the cooling assembly 2 further includes a cooling pipe 22, which passes through the heat conductive block 21 and is located together with the heat conductive block 21 in the hollow groove 312. The cooling pipe 22 is used to transmit a cooling medium, which may be water, oil, or a water-glycol mixture.

[0051] During welding, the cooling medium can be transported to the cooling pipe 22 by a pump so that the cooling medium flows through the heat conductive block 21. The cooling medium absorbs the heat transferred by the heat conductive block 21 and transmits it out to cool the nickel sheet 61. Since the thermal conductivity of the liquid is relatively high and the heat conductive block 21 is in direct contact with the nickel sheet 61, the speed of cooling the nickel sheet 61 can be accelerated, which can meet the cooling requirements under different welding conditions.

[0052] Please combine Figure 3 and Figure 4 In some embodiments, the base 1 has a first direction, a plurality of heat conducting blocks 21 are provided, the plurality of heat conducting blocks 21 are spaced apart along the first direction and connected to the base 1, and each heat conducting block 21 is disposed on the cooling tube 22. A plurality of clamping regions 311 are provided, the plurality of clamping regions 311 are spaced apart along the first direction, the clamping regions 311 are disposed corresponding to the heat conducting blocks 21, and the hollow grooves 312 extend along the first direction.

[0053] Multiple heat-conducting blocks 21 can correspond to multiple battery protection plates 6. Accordingly, multiple clamping areas 311 are set to position the battery protection plates 6. Each heat-conducting block 21 is in contact with a nickel sheet 61. After the clamping assembly 3 is clamped once, multiple battery protection plates 6 can be welded, which saves the number of clamping times of the battery protection plates 6 and helps improve welding efficiency.

[0054] Please combine Figure 3 and Figure 4 In some embodiments, the base 1 has a first direction and a second direction that intersect. The cooling assembly 2 further includes a plurality of cooling tubes 22 and a plurality of heat conductive blocks 21, with the plurality of cooling tubes 22 arranged at intervals along the second direction. The plurality of heat conductive blocks 21 are connected to the base 1 and arranged at intervals along the first direction. Each heat conductive block 21 is penetrated by a plurality of cooling tubes 22, i.e., the plurality of heat conductive tubes sequentially pass through the plurality of heat conductive blocks 21. Each heat conductive block 21 is located within a hollow groove 312, and the clamping area 311 is provided corresponding to the heat conductive block 21.

[0055] Multiple cooling tubes 22 are used to cool each heat-conducting block 21. That is, during welding, the heat of each heat-conducting block 21 can be transferred to multiple cooling fluids, which speeds up the heat transfer speed of the heat-conducting block 21, thereby improving the cooling effect on the nickel sheet 61.

[0056] Please combine Figure 3 and Figure 4In some embodiments, multiple heat conducting blocks 21 are arranged in a row along a first direction. The cooling assembly 2 includes multiple rows of heat conducting blocks 21, and the multiple rows of heat conducting blocks 21 are arranged along a second direction. Each row of heat conducting blocks 21 corresponds to a hollow groove 312. Accordingly, each row of heat conducting blocks 21 is located in its corresponding hollow groove 312. The clamping area 311 is provided corresponding to the heat conducting blocks 21. Therefore, the clamping area 311 can also be divided into multiple rows. Each row of heat conducting blocks 21 is penetrated by multiple cooling pipes 22.

[0057] On the one hand, the multiple rows of clamping areas 311 and the corresponding multiple rows of heat-conducting blocks 21 further increase the number of battery protection plates 6 that can be clamped by the clamping assembly 3 at a single time. At the same time, each heat-conducting block 21 is equipped with multiple streams of cooling fluid to absorb heat, which not only maintains the cooling effect but also improves the welding efficiency.

[0058] On the other hand, the heat conducting blocks 21 are arranged correspondingly to the nickel sheets 61. When a battery protection board 6 includes multiple nickel sheets 61, multiple heat conducting blocks 21 are required. Therefore, when welding a row of battery protection boards 6, multiple rows of heat conducting blocks 21 are required for cooling. Based on this situation, adding multiple rows of heat conducting blocks 21 can not only increase the number of battery protection boards 6 that can be clamped at a time, but also reduce the number of times a single battery protection board 6 needs to be repeatedly clamped to weld additional points.

[0059] Please refer to Figure 5 In some embodiments, the cooling pipe 22 includes an input end 221 and an output end 222 , and the welding cooling device further includes an inlet collecting assembly 4 and an outlet collecting assembly 5 , the inlet collecting assembly 4 is connected to the input end 221 , and the outlet collecting assembly 5 is connected to the output end 222 .

[0060] The inlet manifold assembly 4 connects the various input ends 221, and the outlet manifold assembly 5 connects the various output ends 222. When transporting the cooling medium, the inlet manifold assembly 4 is used to distribute the flow of the cooling tubes 22, while the outlet manifold assembly 5 is used to combine the flow of the cooling tubes 22. The cooling medium is typically transported by pumping. A cooling medium circulation and transport system is composed of a pump, a pipeline, and a cooling medium storage carrier. The inlet manifold assembly 4 and the outlet manifold assembly 5 distribute and unify the cooling medium, which can reduce the number of required pumps and the number of connectors 521 connected to the pumps, thereby simplifying the system.

[0061] Please combine Figure 3 、 Figure 4 and Figure 5 In some embodiments, the inlet manifold assembly 4 includes an inlet manifold 41 , which is connected to the input end 221 . The cooling medium is input through the inlet manifold 41 and then distributed to each cooling medium.

[0062] The outlet manifold assembly 5 includes an outlet manifold 51 and a first cooling unit 52. The first cooling unit 52 is connected to the outlet manifold 51 and the output end 222, respectively. The outlet manifold 51 is connected to the cooling tubes 22 through the first cooling unit 52. The cooling medium in each cooling tube 22 is converged to the outlet manifold 51 through the first cooling unit 52 and outputted uniformly from the outlet manifold 51.

[0063] Specifically, the first cooling section 52 includes a connector 521 and multiple fins 522. The connector 521 is connected to the outlet manifold 51 and the output end 222, respectively. The multiple fins 522 are fixed to the connector 521 and arranged in intervals. When the cooling medium passes through the first cooling section 52, some of the heat it carries is transferred to the connector 521, and then from the connector 521 to each fin 522. The cooling medium is cooled by heat exchange between the fins 522 and the air, maintaining the cooling medium temperature within the desired range.

[0064] In some other embodiments, the inlet header assembly 4 further includes a second cooling portion. The structure and effect of the second cooling portion are the same as those of the first cooling portion 52 and are not described in detail here.

[0065] Please refer to Figure 5 In some embodiments, there are multiple cooling assemblies 2, which are arranged at intervals along the second direction. The inlet manifolds 41 of the multiple cooling assemblies 2 are connected, and the outlet manifolds 51 of the multiple cooling assemblies 2 are connected.

[0066] Each cooling assembly 2 corresponds to a row of battery protection plates 6, and the heat conductive blocks 21 in each cooling assembly 2 are arranged correspondingly to the nickel sheets 61. Multiple cooling assemblies 2 further increase the number of configurable battery protection plates 6. At the same time, the cooling assembly 2 is modularized. When the number of rows of battery protection plates 6 needs to be increased, only the corresponding cooling assembly 2 needs to be arranged, thus achieving the binding of the cooling assembly 2 with the specifications of the battery protection plates 6. When transporting the cooling medium, the cooling medium can be diverted to the cooling pipes 22 of each cooling assembly 2 through a single input point. The cooling medium in each cooling pipe 22 eventually flows back through a single output point, which is conducive to streamlining pipeline design and connection, and also facilitates the distribution and control of the cooling medium.

[0067] Please refer to Figure 6 In some embodiments, the heat conducting block 21 has a connecting channel 211 through which the cooling tube 22 passes. The heat conducting block 21 has a heat dissipation slot 212 extending therethrough, communicating with the connecting channel 211. The heat dissipation slot 212 increases the contact area between the heat conducting block 21 and the air, allowing the heat from the heat conducting block 21 to be quickly transferred to the cooling medium and the surrounding air, thereby improving the cooling effect on the nickel sheet 61.

[0068] The number of the heat dissipation slots 212 can be set to multiple, and the multiple heat dissipation slots 212 are arranged at intervals along the first direction. The multiple heat dissipation slots 212 can further enhance the efficiency of heat exchange between the heat conductive block 21 and the air.

[0069] Please combine Figure 2 、 Figure 3 and Figure 4 In some embodiments, the base 1 has a third direction, which intersects with both the first direction and the second direction. The clamping assembly 3 includes: a carrier plate 31 and a clamping plate 32. The carrier plate 31 is supported on the base 1, and a clamping area 311 and a hollow groove 312 are provided on the carrier plate 31. The clamping area 311 is provided on the side of the carrier plate 31 facing away from the base 1. The clamping area 311 is recessed into the carrier plate 31 along the third direction, forming a groove-like structure, so that the battery protection plate 6 can be placed therein while limiting the displacement of the battery protection plate 6. The hollow groove 312 is provided through the carrier plate 31 and extends along the first direction, thereby communicating with each clamping area 311. The heat conductive block 21 is connected to the base 1. Specifically, the heat conductive block 21 can be fixed to the base 1 by gluing or welding. The heat conductive block 21 is located between the base 1 and the carrier plate 31 and is inserted into the hollow groove 312.

[0070] The clamping plate 32 is rotatably connected to the supporting plate 31 and is used to clamp and fix the battery protection plate 6 in the clamping area 311 . The clamping plate 32 has a welding groove 321 , and the welding groove 321 is correspondingly arranged in the clamping area 311 .

[0071] When the clamping plate 32 rotates and covers the carrier plate 31, the battery protection plate 6 is clamped between the clamping plate 32 and the carrier plate 31. The welding groove 321 exposes the welding position of the battery protection plate 6, facilitating the welding operation. When the clamping plate 32 rotates away from the carrier plate 31, the clamping area 311 is fully exposed, allowing the battery protection plate 6 to be easily and quickly loaded and unloaded. Because the carrier plate 31 is supported on the base 1, the clamping assembly 3 can be completely removed and replaced after welding, facilitating the turnover of the battery protection plate 6 between various processes.

[0072] Please combine Figure 2 、 Figure 3 and Figure 4 In some embodiments, the base 1 has a receiving groove 10 , the carrying plate 31 is partially located in the receiving groove 10 , and the heat conducting block 21 is at least partially located in the receiving groove 10 .

[0073] When the carrier plate 31 is inserted into the receiving groove 10, it plays a role in positioning the carrier plate 31, so that the heat conductive block 21 and the nickel sheet 61 can correspond to and interfere with each other, and in the process of circulating the clamping component 3, the relative position of each clamping component 3 and the base 1 can be kept fixed, saving adjustment and calibration time.

[0074] Please combine Figure 3、 Figure 4 and Figure 5 In some embodiments, the base 1 has a first surface 11 and a second surface 12 arranged along a third direction. The receiving groove 10 is provided on the first surface 11. The second surface 12 is located within the receiving groove 10, forming the bottom of the receiving groove 10 in the third direction. When the supporting plate 31 is inserted into the receiving groove 10, the supporting plate 31 is in contact with the second surface 12. The outer periphery of the base 1 includes a first side surface 13, a second side surface 14, a third side surface 15, and a fourth side surface 16 connected end to end. The first side surface 13 and the third side surface 15 are arranged along the first direction. The base 1 has multiple recesses 17, which are disposed on the first side 13 and the third side 15. Each recess 17 is connected to the receiving groove 10 and extends along the first direction to the second side 12. Each recess 17 penetrates the first side 11 along the third direction. Each recess 17 is corresponding to the inlet manifold 41 and the outlet manifold 51, respectively, so that the inlet manifold assembly 4 and the outlet manifold assembly 5 can be placed in the corresponding recess 17, thereby preventing interference with the placement of the carrier plate 31 on the second side 12 and affecting the fit between the carrier plate 31 and the second side 12. In addition, the recess 17 is disposed on the base 1 rather than the carrier plate 31, which prevents the recess 17 from occupying resources on the carrier plate 31 and ensures the layout of the clamping area 311.

[0075] Please combine Figure 2 and Figure 4 In some embodiments, the clamping plate 32 and the supporting plate 31 are connected by a hinge. The base 1 has a clearance groove 18, which is connected to the receiving groove 10 and is corresponding to the hinge. The clearance groove 18 provides a clearance space for the hinge, allowing the clamping plate 32 to rotate smoothly.

[0076] Please combine Figure 1 and Figure 2 In some embodiments, the cooling device for welding further includes a positioning assembly 7 , which is disposed between the carrier plate 31 and the clamping plate 32 , and the positioning assembly 7 connects the carrier plate 31 and the clamping plate 32 .

[0077] The positioning assembly 7 includes a positioning post 71, a first magnet 73, and a second magnet 74. The positioning post 71 is connected to the carrier plate 31, and the clamping plate 32 has a positioning hole 72, which is arranged corresponding to the positioning post 71. The first magnet 73 is embedded in the carrier plate 31, and the second magnet 74 is embedded in the clamping plate 32, with the first magnet 73 and the second magnet 74 being arranged correspondingly. When the clamping plate 32 rotates to cover the carrier plate 31, the positioning post 71 and the positioning hole 72 are plugged into each other, limiting the relative displacement between the clamping plate 32 and the carrier plate 31. At the same time, the second magnet 74 and the first magnet 73 contact and attract each other, using magnetic attraction to fix the clamping plate 32 and the carrier plate 31.
