[0002] This application is based on and claims priority to Chinese Patent Application No. 202411841926.3, filed on December 13, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of battery manufacturing technology, and in particular to a casting and welding device for terminal posts and a solution for addressing poor casting and welding porosity in terminal posts. Background Technology

[0004] A terminal block is a component that connects directly to the busbar at one end and to either an external conductor or a terminal of an adjacent individual cell in a battery pack at the other end. Terminal blocks serve to connect electrical components within a battery pack and are commonly used for connecting storage batteries.

[0005] With rising labor and material costs, the overall manufacturing cost of batteries is also increasing. However, the market demand is for high quality at a low price. To meet this demand, higher requirements need to be placed on the terminal block manufacturing process. While optimizing the tin plating process for the terminal block components to a bare copper dip-casting flux and tin-dip process has saved some costs, the porosity defect rate of the formed terminal blocks is relatively high, reaching about 4%, during mass production. To address this, we optimized the bare copper part forming process. The optimized process produces terminal copper parts with a zero porosity defect rate, low cost, and qualified torque, thus improving the battery's market competitiveness. The existing bare copper part process for terminal copper parts is: bare copper part + dip-casting flux + tin-dip solution + casting. The flux composition is zinc chloride + phosphorous acid + pure water. Under high-temperature molten lead, it reacts rapidly, producing a large amount of white gas. This large amount of gas is difficult to expel from the mold in a short time. The gas that does not escape is trapped by the cooled molten lead, resulting in porosity and causing the terminal blocks to be defective. Summary of the Invention

[0006] This application aims to at least partially address one of the technical problems in the related art.

[0007] Therefore, one object of this application is to provide a casting and welding device for pole terminals.

[0008] Another objective of this application is to provide a solution for the problem of poor welding porosity in pole terminal castings.

[0009] According to this application, a casting and welding device for a terminal post includes a load-bearing plate and a flux tank on the top of the load-bearing plate. A solder bath is also installed on the top of the load-bearing plate. A dispensing mechanism is provided on the top of the flux tank and the solder bath. An immersion mechanism is provided on one side of the load-bearing plate. A feeding mechanism is provided on one side of the immersion mechanism. A filtering mechanism is provided at the bottom of the feeding mechanism.

[0010] According to the present application, a casting and soldering device for a terminal post is used to dissolve the zinc chloride and phosphorous acid components in the flux adhering to the surface of the terminal post after it has been dipped in flux and molten solder by immersing the terminal post material in alcohol for a specified period of time. This avoids the flux reacting rapidly under the contact of high-temperature molten lead, producing a large amount of white gas. The large amount of gas is difficult to expel from the mold in a short time, and the gas that is not expelled is trapped by the cooled molten lead, resulting in pores. This greatly improves the pass rate of the terminal post after molding.

[0011] A solution to the problem of poor weld porosity in pole terminal castings according to this application includes the following steps:

[0012] Place multiple pole terminal materials into the material slots of the material frame;

[0013] The horizontal displacement cylinder is activated to push the material frame at the bottom of the displacement slider to move laterally to the top of the flux tank, and the vertical displacement cylinder is activated to move the material frame down into the flux tank, so that the material is immersed in the flux to complete the flux application.

[0014] After resetting the material frame using the longitudinal displacement cylinder, activate the lateral displacement cylinder to move the material frame horizontally above the molten solder tank, and then use the longitudinal displacement cylinder to drive the material frame deeper into the molten solder tank to complete the molten solder coating.

[0015] After the coating is completed, the longitudinal displacement cylinder is activated to lift the material frame above the feeding guide plate and the servo motor is turned on. The servo motor drives the deflection block and the material frame to deflect through the output shaft and pour out the material. The material rolls into the alcohol tank through the feeding guide plate.

[0016] The drive motor is turned on, which drives the drive shaft to rotate on the drive bearing. The drive shaft drives multiple sets of drive shafts to rotate synchronously through the transverse belt on the double belt pulley. It also drives the guide roller to rotate on the guide bearing through the longitudinal belt on the double belt pulley. Thus, multiple materials are moved in the alcohol tank by friction. The soaking time of the materials in the alcohol is controlled by controlling the motor speed.

[0017] The soaked material falls into the collection frame of the collection box through the feeding chute. Then, the lifting cylinder is activated to move the collection frame up to the discharge chute, and the soaked material is discharged through the guide ramp on the collection frame.

[0018] The alcohol in the alcohol tank will pass through the drain hole at the bottom of the collection frame, the inner plate of the leakage, and the filter hole at the bottom of the impurity collection drawer before being stored at the bottom of the storage tank. Impurities will remain in the impurity collection drawer. The alcohol at the bottom of the tank is extracted by starting the liquid pump and re-injected into the alcohol tank for circulation and soaking.

[0019] According to the solution of the above-described device for solving the problem of poor welding porosity in pole terminal according to this application, the advantages are as follows:

[0020] (1) This application uses the horizontal displacement cylinder and the vertical displacement cylinder in the liquid-dispensing mechanism to drive the material in the pole terminal of the material frame to displace the material to pick up the flux and molten solder. After the liquid-dispensing is completed, the servo motor drives the material frame to deflect, so that the material can be poured into the alcohol tank. This liquid-dispensing method is highly efficient and avoids the contact between the staff and the flux and molten solder, thereby greatly improving the practicality and safety of the device.

[0021] (2) This application collects the material after the liquid is applied into the storage tank through the feeding guide plate and soaks it in the alcohol in the tank. During soaking, the drive motor and various belts and pulleys drive multiple sets of guide rollers to rotate, so that the material can be moved and transported by the friction between them. The motor speed can be controlled by the control unit, so the soaking time of the material in the alcohol tank can be controlled by controlling the speed of the guide rollers. After soaking for a specified time, the flux on the surface of the tinned copper parts can be dissolved. Because the zinc chloride and phosphorous acid components in the flux are easily soluble in alcohol, and alcohol is volatile, when the lead liquid of the tinned bare copper parts is cast after soaking, the presence of zinc chloride + phosphorous acid + pure water on the surface of the material will be avoided. Under the high temperature of the lead liquid, the reaction will be rapid, producing a large amount of white gas. The large amount of gas is difficult to be discharged from the mold in a short time. The gas that is not discharged is wrapped by the lead liquid after cooling, which produces pores.

[0022] (3) This application collects the soaked material in the collection box and lifts it up by the lifting cylinder. When it rises to the discharge trough, the material soaked in alcohol is discharged by the ramp. The alcohol overflowing from the alcohol tank is filtered through the filter hole on the impurity collection drawer in the storage tank. The filtered alcohol is pumped back into the alcohol tank for recycling by the pump, which facilitates material discharge, reduces resource damage, and further reduces production costs.

[0023] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] Example: As shown in Figures 1-10, this example provides a casting and welding device and method for pole terminals, including a load-bearing plate 1, a flux tank 2 on the top of the load-bearing plate 1, a solder bath tank 3 installed on the top of the load-bearing plate 1, a liquid dispensing mechanism 4 on the top of the flux tank 2 and the solder bath tank 3, an immersion mechanism 5 on one side of the load-bearing plate 1, a feeding mechanism 6 on one side of the immersion mechanism 5, and a filtering mechanism 7 at the bottom of the feeding mechanism 6.

[0039] Among them, the load-bearing plate 1 provides support for the flux tank 2 and the solder tank 3; the flux tank 2 is a flux storage unit and the solder tank 3 is a solder storage unit.

[0040] The liquid dispensing mechanism 4 includes a U-shaped displacement frame 401 located on top of the flux tank 2 and the solder tank 3. A displacement slider 402 is movably connected to the top of the U-shaped displacement frame 401. A transverse displacement cylinder 403 is installed on one side of the side plate of the U-shaped displacement frame 401. An extension block 404 is fixedly connected to one side of the displacement slider 402. A longitudinal displacement plate 405 is movably connected to the bottom of the extension block 404. A longitudinal displacement cylinder 406 is installed on the top of the extension block 404. Two sets of telescopic rods 407 are installed on the top of the longitudinal displacement plate 405. The two sets of telescopic rods 407 are symmetrically distributed on the top of the longitudinal displacement plate 405.

[0041] The U-shaped displacement frame 401 provides support for the lower component. Its outer groove can be movably connected to the bottom protrusion of the displacement slider 402. The displacement slider 402 and the lower component can be moved laterally by the drive of the lateral displacement cylinder 403, so as to pick up different liquids in the box. The extension block 404 and the longitudinal displacement plate 405 provide support for the lower component. The longitudinal displacement plate 405 can be raised and lowered by the longitudinal displacement cylinder 406. The stability of the longitudinal displacement plate 405 and the lower component during the raising and lowering is ensured by the extension and extension guide of two sets of telescopic rods 407, which facilitates unloading.

[0042] The liquid dispensing mechanism 4 also includes two sets of deflection bearing rods 408 fixedly connected to the bottom of the longitudinal displacement plate 405. The two sets of deflection bearing rods 408 are symmetrically distributed at the bottom of the longitudinal displacement plate 405. A deflection block 409 is movably connected to the bottom of the longitudinal displacement plate 405. A servo motor 410 is installed on one side of the deflection bearing rod 408. Two sets of movable rotating shafts 411 are provided on the outer side of the deflection block 409. The two sets of movable rotating shafts 411 are symmetrically distributed on the outer side of the deflection block 409. Multiple sets of mating bolts 412 are threadedly connected to one side of the output shaft of the servo motor 410. The multiple sets of mating bolts 412 are arranged in a ring on one side of the output shaft of the servo motor 410. A motor bracket 413 is provided on one side of the deflection bearing rod 408.

[0043] Among them, two sets of deflection bearing rods 408 provide support for the deflection block 409 and can be connected to two sets of movable rotating shafts 411 on the deflection block 409, thereby realizing the deflection of the deflection block 409. This deflection operation is driven by the servo motor 410. The use of multiple sets of docking bolts 412 realizes the docking of the servo motor 410 with a set of movable rotating shafts 411, ensuring stable transmission of motor power. The motor bracket 413 is set to provide stable support for the servo motor 410.

[0044] The liquid dispensing mechanism 4 also includes a material frame 414 fixedly connected to the bottom of the deflection block 409. A material frame 415 is provided on the top of the material frame 414. Multiple sets of material placement slots 416 are provided on the top of the material frame 414, and the multiple sets of material placement slots 416 are linearly distributed on the top of the material frame 414.

[0045] Among them, the material frame 414 is a material storage component for the pole terminal. This component uses multiple sets of material placement slots 416 to place and limit the material, and its bottom opening can easily contact the liquid in the flux box 2 and the solder bath 3. It is fixedly connected to the upper deflection block 409 through the material frame 415 to ensure the stability during horizontal and vertical displacement and deflection.

[0046] The soaking mechanism 5 includes an alcohol tank 501 located on one side of the load-bearing plate 1. One end of the alcohol tank 501 is provided with a feeding guide plate 502. The interior of the alcohol tank 501 is provided with a liquid storage chamber 503. The inner wall of the alcohol tank 501 is provided with two sets of driving wall grooves 504, which are symmetrically distributed on the inner wall of the alcohol tank 501. The interior of the alcohol tank 501 is provided with multiple sets of guide rollers 505, which are linearly distributed inside the alcohol tank 501. Both ends of the guide rollers 505 are provided with guide bearings 506, and a bearing support plate 507 is provided between the multiple sets of guide bearings 506.

[0047] The alcohol tank 501 is an alcohol storage unit. The unit is fed by the feeding guide plate 502 and stored in the storage chamber 503. The two sets of drive wall grooves 504 can hold the drive components of the guide rollers 505. The multiple sets of guide rollers 505 are connected to the guide bearings 506 to rotate, so that the material can be moved and transported by friction between them and the material.

[0048] The soaking mechanism 5 also includes a single belt pulley 508 fixedly connected to one end of the guide roller 505. Multiple sets of drive shafts 509 are provided on the top of the side wall of the alcohol tank 501. The multiple sets of drive shafts 509 are linearly distributed on the top of the side wall of the alcohol tank 501. A drive bearing 510 is provided at one end of the drive shaft 509. A double belt pulley 511 is fixedly connected to the other end of the drive shaft 509. A longitudinal belt 512 is provided on the outside of the double belt pulley 511. A transverse belt 513 is provided on the outside of the double belt pulley 511. A drive motor 514 is installed on one side of the alcohol tank 501. A discharge chute 515 is opened at the other end of the alcohol tank 501.

[0049] Multiple drive shafts 509 are supported by drive bearings 510. When the drive motor 514 is energized, it drives a set of double-belt pulleys 511 to rotate. These pulleys rotate the guide rollers 505 by engaging with the single-belt pulleys 508 on the lower guide rollers 505 via the longitudinal belt 512. The rotation of the multiple drive shafts 509 is achieved by engaging with the belt grooves on the other side of the transverse belt 513, further realizing the synchronous rotation of the multiple guide rollers 505 and thus transporting materials. The motor speed can be controlled by the control unit. Therefore, the soaking time of the material in the alcohol tank 501 can be controlled by controlling the rotation speed of the guide roller 505. After soaking for a specified time, the flux on the surface of the tinned copper parts can be dissolved. Because the zinc chloride and phosphorous acid components in the flux are easily soluble in alcohol, and alcohol is volatile, when the lead liquid is cast after soaking, the presence of zinc chloride + phosphorous acid + pure water on the surface of the material will be avoided. Under the high temperature of the lead liquid, the rapid reaction will produce a large amount of white gas. The large amount of gas is difficult to be discharged from the mold in a short time. The gas that is not discharged is wrapped by the lead liquid after cooling, which produces pores.

[0050] The feeding mechanism 6 includes a collection box 601 located on one side of the alcohol tank 501. The top of the collection box 601 has a feeding trough 602. Two sets of triangular limiting plates 603 are fixedly connected to the top of the side wall of the collection box 601. The two sets of triangular limiting plates 603 are symmetrically distributed on the top of the side wall of the collection box 601. A discharge trough 604 is located on one side of the collection box 601.

[0051] The collection box 601 is a material collection unit after soaking. The unit collects the material through the feed trough 602, limits the falling material through two sets of triangular limiting plates 603 to prevent the material from falling off, and discharges the material through the discharge trough 604.

[0052] The feeding mechanism 6 also includes a material collection frame 605 that is movably connected inside the collection box 601. The bottom plate of the material collection frame 605 is provided with a guide ramp 606. Multiple sets of drainage holes 607 are provided at the bottom of the bottom plate of the material collection frame 605. The multiple sets of drainage holes 607 are rectangularly distributed at the bottom of the bottom plate of the material collection frame 605. The top of the collection box 601 is fixedly connected to a U-shaped lifting frame 608. The top of the material collection frame 605 is fixedly connected to a material frame structure frame 609. A lifting cylinder 610 is installed on the top of the U-shaped lifting frame 608.

[0053] The material collection frame 605 is a material collection component. The material collected in the frame can be discharged through the inclined surface of the guide ramp 606, and the alcohol flowing out of the alcohol tank 501 can be drained through multiple sets of drainage holes 607, which facilitates the recycling of alcohol. The U-shaped lifting frame 608 provides support for the material collection frame 605, and the lifting cylinder 610 drives the material frame structure 609 and the material collection frame 605 to rise and fall along the U-shaped lifting frame 608, which facilitates the lifting of the material collection frame 605 to the discharge chute 604 to discharge the material.

[0054] The filtration mechanism 7 includes a liquid storage tank 701 located at the bottom of the alcohol tank 501. The liquid storage tank 701 has a leakage inner plate 702 inside. A miscellaneous collection drawer 703 is movably inserted into one side of the liquid storage tank 701. A drawer outer plate 704 is provided on one side of the miscellaneous collection drawer 703. A sealing ring 705 is provided on one side of the drawer outer plate 704. Two sets of fastening bolts 706 are threadedly connected to one side of the outer support leg of the drawer outer plate 704. The two sets of fastening bolts 706 are symmetrically distributed on one side of the outer support leg of the drawer outer plate 704.

[0055] The storage tank 701 is an alcohol collection and storage unit. Its internal leakage plate 702 can limit the collection frame 605, and the multiple sets of filter holes at the bottom of the impurity collection drawer 703 can filter out impurities in the alcohol, preventing residual impurities on the material from entering the circulation equipment and damaging the equipment or causing secondary contamination of the material. The outer plate 704 of the drawer is a limiting plate for the impurity collection drawer 703. Its outer fastening bolts 706 can be locked by threaded connection with the threaded holes on the storage tank 701. At the same time, when locked, the sealing ring 705 can be pressed, thereby achieving a seal at the connection between the impurity collection drawer 703 and the storage tank 701, preventing alcohol from overflowing and wasting resources.

[0056] The filtration mechanism 7 also includes a liquid pump 707 installed on one side of the liquid storage tank 701, and a liquid injection pipe 708 is installed on one side of the liquid pump 707.

[0057] When powered on, the pump 707 can extract the filtered alcohol from the bottom of the storage tank 701 and re-inject it into the alcohol tank 501 through the injection pipe 708 for recycling.

[0058] As shown in Figure 11, a solution for addressing poor weld porosity in pole terminal components includes the following steps:

[0059] Step S1001: Place multiple terminal block materials into the material slots of the material frame;

[0060] Step S1002: Start the lateral displacement cylinder to push the material frame at the bottom of the displacement slider to move laterally to the top of the flux tank, and start the longitudinal displacement cylinder to move the material frame down into the flux tank. The material is immersed in the flux to complete the flux application.

[0061] Step S1003: After resetting the material frame by using the longitudinal displacement cylinder again, start the lateral displacement cylinder to move the material frame horizontally above the tin bath, and use the longitudinal displacement cylinder to drive the material frame into the tin bath to complete the tin plating.

[0062] Step S1004: After the pickling is completed, the longitudinal displacement cylinder is activated to lift the material frame above the feeding guide plate and the servo motor is turned on. The servo motor drives the deflection block and the material frame to deflect through the output shaft and pour out the material. The material rolls into the alcohol tank through the feeding guide plate.

[0063] Step S1005: Turn on the drive motor to drive the drive shaft to rotate on the drive bearing. The drive shaft drives multiple sets of drive shafts to rotate synchronously through the transverse belt on the double belt pulley, and drives the guide roller to rotate on the guide bearing through the longitudinal belt on the double belt pulley. Thus, multiple materials are moved in the alcohol tank by friction. The soaking time of the materials in the alcohol is controlled by controlling the motor speed.

[0064] Step S1006: The soaked material falls into the collection frame of the collection box through the feeding chute. Then, the lifting cylinder is turned on to move the collection frame up to the discharge chute. The soaked material is discharged through the guide ramp on the collection frame.

[0065] Step S1007: The alcohol in the alcohol tank will pass through the drain hole at the bottom of the collection frame, the inner plate of the leakage, and the filter hole at the bottom of the impurity collection drawer and be stored at the bottom of the storage tank. Impurities will remain in the impurity collection drawer. The alcohol at the bottom of the tank is extracted by starting the liquid pump and re-injected into the alcohol tank for circulation and soaking.

[0066] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application 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 application.

[0067] According to the solution of the above-described device for solving the problem of poor welding porosity in pole terminal according to this application, the advantages are as follows:

[0068] (1) This application uses the horizontal displacement cylinder and the vertical displacement cylinder in the liquid-dispensing mechanism to drive the material in the pole terminal of the material frame to displace the material to pick up the flux and molten solder. After the liquid-dispensing is completed, the servo motor drives the material frame to deflect, so that the material can be poured into the alcohol tank. This liquid-dispensing method is highly efficient and avoids the contact between the staff and the flux and molten solder, thereby greatly improving the practicality and safety of the device.

[0069] (2) This application collects the material after the liquid is applied into the storage tank through the feeding guide plate and soaks it in the alcohol in the tank. During soaking, the drive motor and various belts and pulleys drive multiple sets of guide rollers to rotate, so that the material can be moved and transported by the friction between them. The motor speed can be controlled by the control unit, so the soaking time of the material in the alcohol tank can be controlled by controlling the speed of the guide rollers. After soaking for a specified time, the flux on the surface of the tinned copper parts can be dissolved. Because the zinc chloride and phosphorous acid components in the flux are easily soluble in alcohol, and alcohol is volatile, when the lead liquid of the tinned bare copper parts is cast after soaking, the presence of zinc chloride + phosphorous acid + pure water on the surface of the material will be avoided. Under the high temperature of the lead liquid, the reaction will be rapid, producing a large amount of white gas. The large amount of gas is difficult to be discharged from the mold in a short time. The gas that is not discharged is wrapped by the lead liquid after cooling, which produces pores.

[0070] (3) This application collects the soaked material in the collection box and lifts it up by the lifting cylinder. When it rises to the discharge trough, the material soaked in alcohol is discharged by the ramp. The alcohol overflowing from the alcohol tank is filtered through the filter hole on the impurity collection drawer in the storage tank. The filtered alcohol is pumped back into the alcohol tank for recycling by the pump, which facilitates material discharge, reduces resource damage, and further reduces production costs.

A solution for resolving poor weld porosity in pole terminal castings using the apparatus according to any one of claims 1-10, wherein, Includes the following steps: Place multiple pole terminal materials into the material slots of the material frame; The horizontal displacement cylinder is activated to push the material frame at the bottom of the displacement slider to move laterally to the top of the flux tank, and the vertical displacement cylinder is activated to move the material frame down into the flux tank, so that the material is immersed in the flux to complete the flux application. After resetting the material frame using the longitudinal displacement cylinder, activate the lateral displacement cylinder to move the material frame horizontally above the molten solder tank, and then use the longitudinal displacement cylinder to drive the material frame deeper into the molten solder tank to complete the molten solder coating. After the coating is completed, the longitudinal displacement cylinder is activated to lift the material frame above the feeding guide plate and the servo motor is turned on. The servo motor drives the deflection block and the material frame to deflect through the output shaft and pour out the material.
