Description

Technical Field

[0001] This invention relates to the field of welding cooling technology, and more specifically, to an automatic welding cooling device for metallized thin-film capacitors. Background Technology

[0002] Metallized film capacitors are capacitors made by winding organic plastic film as dielectric and metallized film as electrodes (except for laminated structures). They have excellent electrical characteristics, high stability and long life, and can meet various applications.

[0003] Traditional automatic welding equipment locks the welding electrode head through a mounting base and a welding electrode locking head, and moves the welding electrode head through a sliding mounting base to bring the welding electrode head into contact with the metallized film capacitor. Its cooling structure is integrated in the sliding mounting base, which can cool the bottom of the welding electrode head through coolant circulation.

[0004] During welding, the welding tip generates significant heat due to the large current passing through it. However, in existing traditional cooling methods, only the bottom of the welding tip is in contact with the mounting base, which has cooling properties. This means that only one surface is effectively dissipating heat, while the rest of the welding tip is not effectively cooled. During long-term continuous operation, the welding tip temperature is high, the conductivity decreases, and the high temperature damages the core material of the metallized film capacitor. Furthermore, the probability of incomplete welding increases, leading to a significant increase in potential electrical performance issues in the capacitor product after welding.

[0005] In existing traditional automatic welding equipment for metallized film capacitors, the electrode head is adjusted in an open manner during replacement. This requires manual adjustment of the electrode head's position without support to meet the required spacing between the welding heads on both sides of the capacitor and the center of the capacitor body. However, in actual use, improper adjustment can lead to deviations in the accuracy of the reference position, resulting in a common welding defect, such as "over-weighted or over-deep welding" or "incomplete welding".

[0006] In the welding process of metallized film capacitors, there are four welding points. Wires need to be welded to both sides of the capacitor body, and each welding wire has two welding points. During welding, due to temperature differences between the welding electrodes, the two welding points of the welding wire can easily result in different welding conditions, such as warping or deformation. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides an automatic welding and cooling device for metallized film capacitors, which uses a wrap-around circulating pipe to achieve temperature equalization and overheating cooling of the welding electrode heads on the same side.

[0008] This invention is achieved through the following technical solution: an automatic welding and cooling device for metallized thin film capacitors, including a base, a mounting seat slidably connected to the base, a first driving member for driving the mounting seat to slide on the base, and two parallel mounting holes opened in the mounting seat, each of which can be detachably connected to a welding electrode head;

[0009] The mounting hole sidewall is integrated with a circulation pipe. Both mounting holes are within the range of the circulation pipe. A cooling pipe is installed inside the circulation pipe. Both ends of the cooling pipe extend out of the circulation pipe. The cooling pipe is connected to a pump body. The pump body is used to inject coolant into the cooling pipe. A heat-conducting agent is filled between the circulation pipe and the cooling pipe.

[0010] A pump actuation box is fixedly connected to one side of the mounting base. The pump actuation box is equipped with a first check valve and a second check valve. The first check valve and the second check valve are in opposite directions. The first check valve and the second check valve are respectively connected to the circulation pipeline. A piston plate is provided inside the pump actuation box. An elastic element is provided between the piston plate and the inner side wall of the pump actuation box. A push rod is fixedly connected to the end of the piston plate away from the elastic element. A stop plate is provided on one side of the base. The stop plate extends into the stroke range of the push rod.

[0011] Furthermore, the outer side of the cooling pipe has several folds.

[0012] Furthermore, the pleats are elastic sheets, and the cooling pipes have rigid pipe sections at both ends. The rigid pipe sections extend out of the circulation pipe, and a sealing gasket is provided where the rigid pipe sections extend out of the circulation pipe. The mounting base is provided with a second driving component for driving the rigid pipe sections to probe into and out of the circulation pipe.

[0013] Furthermore, a height adjustment bracket is provided at the bottom of the mounting base, which is used to adjust the height of the mounting hole.

[0014] Furthermore, a locking bracket is fixedly connected to one side of the mounting base, and a tailstock is fixedly connected to the bottom of the end of the locking bracket away from the mounting base. A threaded hole is provided on the tailstock, and a threaded post is threadedly connected inside the threaded hole. The threaded post is used to be inserted into the mounting hole by rotation.

[0015] Furthermore, a heat insulation block is fixedly connected to one end of the threaded post near the mounting base.

[0016] Furthermore, a rotating disk is fixedly connected to the end of the threaded post away from the mounting base.

[0017] Furthermore, a positioning block is provided on the side of the mounting base away from the locking bracket, the block extends into the mounting hole, and a ladder groove is provided on the side of the positioning block near the mounting hole.

[0018] Furthermore, a distance sensor is provided at the end of the mounting base away from the locking bracket.

[0019] Furthermore, the abutment is slidably connected to the base, the abutment is slidably connected with a locking bolt, and the base is provided with several locking buckles.

[0020] The technical solution of the present invention has at least the following beneficial effects:

[0021] When soldering metallized film capacitors, soldering leads need to be soldered to both sides. Each soldering lead has two solder joints. Therefore, the mounting base has two mounting holes for mounting soldering tips. The first driving element moves the mounting base closer to the metallized film capacitor to solder the two solder joints. By installing soldering equipment on both sides of the metallized film capacitor, four solder joints can be soldered simultaneously.

[0022] The mounting base is used to install the welding electrode head through the mounting holes. In this way, the circulation pipe is integrated into the mounting base, which can fully wrap the welding electrode head, so that the welding electrode head can be cooled from all sides. Compared with the existing technology that only cools the bottom, the effect is better and the heat transfer is more uniform.

[0023] Because both welding electrodes contact the welding wire simultaneously during welding, a significant temperature difference between them can cause one weld point to melt or solidify faster than the other, potentially leading to the welding wire lifting or deforming. Therefore, a cooling pipe is built into the circulation pipe, with a heat-conducting agent filling the space between the circulation pipe and the cooling pipe. This heat-conducting agent effectively conducts the temperature of the welding electrodes, allowing the two electrodes in the mounting bracket to conduct heat to each other, thus reducing the temperature difference between them.

[0024] Since the cooling pipe only injects liquid when cooling is needed, prolonged contact with the welding electrode tip would affect its normal temperature rise. Furthermore, the coolant's boiling point of 100-160℃ is mismatched with the welding electrode tip temperature during welding, failing to balance the temperatures of the two welding electrodes. Therefore, the cooling pipe is integrated within the circulation pipe. This ensures the cooling pipe's coverage is the same as the circulation pipe, preventing them from occupying space and affecting coverage. The cooling pipe is connected to the pump body, allowing for the injection and circulation of coolant. The coolant first conducts heat to the heat transfer agent, cooling it, and then uses the heat transfer agent to cool the two welding electrodes.

[0025] During welding operations, the first drive unit continuously moves the mounting base closer to and away from the metallized film capacitor. Therefore, a pump-driven cartridge is incorporated. When the mounting base approaches the metallized film capacitor, its push rod abuts against the backing plate, pushing the piston plate and compressing the space within the pump-driven cartridge. This forces the heat transfer fluid out through the first one-way valve. Subsequently, as the mounting base moves away from the metallized film capacitor, an elastic element pushes the piston plate open, expanding the space within the pump-driven cartridge. The cartridge then draws in the heat transfer fluid through the second one-way valve. Thus, as long as the first drive unit operates, the heat transfer fluid continuously circulates through the pump-driven cartridge, ensuring constant circulation without the need for an additional pump.

[0026] Compared with existing technologies, this solution adopts a wrap-around circulating pipeline, which can effectively improve the heat exchange performance of the welding electrode head. By setting up built-in cooling pipes and a pump-driven casing, and with the help of the first driving component to drive the displacement during the welding action, the circulating pipeline can simultaneously reduce the temperature difference between the two welding electrodes and cool the welding electrodes.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1

[0041] As attached Figures 1-8 As shown, an automatic welding and cooling device for metallized film capacitors includes a base 1, a mounting seat 2 slidably connected to the base 1, a first driving component 3 (an electric lead screw) for driving the mounting seat 2 to slide on the base 1, and two parallel mounting holes 4 inside the mounting seat 2. A welding electrode 5 is detachably connected to each mounting hole 4, and the mounting seat 2 has a connector for energizing the welding electrode 5. A height adjustment bracket 20, a hydraulically driven control bracket, is provided at the bottom of the mounting seat 2 for adjusting the height of the mounting holes 4.

[0042] The mounting hole 4 has an integrated circulation pipe 6 on its side wall. Both mounting holes 4 are within the working range of the circulation pipe 6. A cooling pipe 7 is installed inside the circulation pipe 6. Both ends of the cooling pipe 7 extend out of the circulation pipe 6. The cooling pipe 7 is connected to a pump body, which is used to inject coolant into the cooling pipe 7. Several pleats 16 are provided on the outside of the cooling pipe 7. A heat transfer agent 8 is filled between the circulation pipe 6 and the cooling pipe 7. The heat transfer agent 8 is a liquid metal heat transfer agent.

[0043] The pump housing 9 is bolted to one side of the mounting base 2. The pump housing 9 is provided with a first check valve 10 and a second check valve 11. The first check valve 10 and the second check valve 11 are in opposite directions. The first check valve 10 and the second check valve 11 are respectively connected to the circulation pipe 6. In this embodiment, the circulation pipe 6 is cut into two sections in the middle. The first check valve 10 and the second check valve 11 are respectively connected to the two sections of the circulation pipe 6. This makes the positions of the first check valve 10 and the second check valve 11 more concentrated. The pump housing 9 is provided with a piston plate 12. An elastic element 13 is provided between the piston plate 12 and the inner side wall of the pump housing 9. A push rod 14 is fixedly connected to the end of the piston plate 12 away from the elastic element 13. A stop plate 15 is provided on one side of the base 1. The stop plate 15 extends into the stroke range of the push rod 14.

[0044] A locking bracket 21 is bolted to one side of the mounting base 2. A tailstock 22 is welded to the bottom of the end of the locking bracket 21 away from the mounting base 2. The tailstock 22 has a threaded hole 23, and a threaded post 24 is threaded into the threaded hole 23. The threaded post 24 is used to rotate and insert into the mounting hole 4. A heat insulation block is bolted to the end of the threaded post 24 near the mounting base 2. A rotating disc 25 is bolted to the end of the threaded post 24 away from the mounting base 2.

[0045] The mounting base 2 has a positioning block 26 on the side away from the locking bracket 21. The block extends into the mounting hole 4. The positioning block 26 has a ladder groove 27 on the side near the mounting hole 4.

[0046] When soldering a metallized film capacitor, soldering wires need to be soldered to both sides, with each soldering wire having two solder joints. Therefore, the mounting base 2 has two mounting holes 4 for mounting soldering tips 5. The first driving component 3 then drives the mounting base 2 closer to the metallized film capacitor to solder the two solder joints. By installing soldering equipment on both sides of the metallized film capacitor, four solder joints can be soldered simultaneously.

[0047] During use, the height of the mounting hole 4 can be adjusted using the height adjustment bracket 20 to make the height of the mounting hole 4 flush with the area to be welded. Since both welding electrodes 5 are installed in the mounting hole 4, the integrated design of the mounting base 2 can keep the two welding electrodes 5 at the same height, effectively avoiding the abnormal installation state of the welding electrodes 5 on the same side being one in front of the other.

[0048] During installation, insert the soldering tip 5 into the mounting hole 4, ensuring that all contact surfaces of the soldering tip 5 are tightly against the side wall of the mounting hole 4. Use the rotary table 25 to rotate the threaded post 24; the threaded post 24 will then extend into the mounting hole 4, pushing the soldering tip 5 further into the hole. Since the other end of the mounting base 2 has a positioning block 26, the soldering tip 5 is in position when it abuts against the positioning block 26. The stepped groove 27 on the positioning block 26 keeps the soldering tip 5 slightly protruding from the mounting base 2. Because the welding wire also has thickness, the thickness of the positioning block 26 only needs to be less than the thickness of the welding wire to ensure contact between the soldering tip 5 and the welding wire.

[0049] Mounting base 2 installs welding electrode head 5 through mounting hole 4. In this way, circulation pipe 6 is integrated into mounting base 2, which can fully wrap welding electrode head 5, so that welding electrode head 5 can be cooled from all sides when cooling. Compared with the existing technology that only cools the bottom, the effect is better and the heat control is more uniform.

[0050] Because both soldering electrodes 5 contact the welding wire simultaneously during welding, a significant temperature difference between them can cause one solder joint to melt or solidify faster than the other, potentially leading to the welding wire lifting or deforming. Therefore, a cooling pipe 7 is built into the circulation pipe 6, and a heat-conducting agent 8 is filled between the circulation pipe 6 and the cooling pipe 7. The heat-conducting agent 8 effectively conducts the temperature of the soldering electrodes 5, and through its heat conduction capacity, allows the two soldering electrodes 5 in the mounting base 2 to conduct heat to each other, reducing the temperature difference between them.

[0051] Since the cooling pipe 7 only injects liquid when cooling is needed, prolonged application to the soldering tip 5 would affect its normal temperature rise. Furthermore, the boiling point of the coolant is 100-160℃, which is mismatched with the temperature of the soldering tip 5 during welding, failing to balance the temperature of the two soldering tips 5. Therefore, the cooling pipe 7 is integrated into the circulation pipe 6. This ensures that the cooling pipe 7 and the circulation pipe 6 have the same coverage, preventing them from occupying space and affecting coverage. The cooling pipe 7 is connected to the pump body, allowing the pump to inject and circulate coolant. The coolant first conducts heat to the heat transfer agent 8, cooling it, and then uses the heat transfer agent 8 to cool the two soldering tips 5. Because both the coolant and the heat transfer agent 8 are liquids, their fluidity allows them to adhere to the irregularly shaped contact surface. Therefore, pleats 16 can be incorporated to increase the heat exchange performance of the coolant and the heat transfer agent 8, enabling the coolant to quickly remove heat from the heat transfer agent 8.

[0052] During welding operations, the first drive unit 3 continuously drives the mounting base 2 closer to and away from the metallized film capacitor. Therefore, a pump-driven cartridge 9 is provided. When the mounting base 2 approaches the metallized film capacitor, the push rod 14 of the pump-driven cartridge 9 abuts against the abutment plate 15, pushing the piston plate 12 and compressing the space inside the pump-driven cartridge 9, squeezing the heat transfer agent 8 out of the first one-way valve 10. Subsequently, when the mounting base 2 moves away from the metallized film capacitor, the elastic element 13 pushes the piston plate 12 open, expanding the space inside the pump-driven cartridge 9. The pump-driven cartridge 9 then draws in the heat transfer agent 8 through the second one-way valve 11. This suction and release keeps the heat transfer agent 8 flowing. Thus, as long as the first drive unit 3 is running, the heat transfer agent 8 will continuously circulate through the pump-driven cartridge 9, ensuring that the heat transfer agent 8 is always circulating without the need for an additional pump.

[0053] Example 2

[0054] The difference from the above embodiment is that the pleat 16 is an elastic sheet, the cooling pipe 7 has rigid pipe sections 17 at both ends, the rigid pipe sections 17 extend out of the circulation pipe 6, the rigid pipe sections 17 are provided with sealing gaskets 18 at the point where the rigid pipe sections 17 extend out of the circulation pipe 6, and the mounting base 2 is provided with a second driving member 19 for driving the rigid pipe sections 17 to enter and exit the circulation pipe 6. The second driving member 19 is a cylinder, and the output shaft of the cylinder is fixedly connected to the rigid pipe.

[0055] Although the cooling pipe 7 can cool the welding tip 5 by changing the temperature of the heat transfer medium 8, the heat transfer medium 8 always separates the pipe, resulting in a slow conduction response. Since the heat transfer medium 8 is a fluid, the cooling pipe 7 can move and change position within the heat transfer medium 8.

[0056] During cooling, the second drive unit 19 reduces the length of the cooling pipe 7 within the circulation pipe 6 by adjusting the insertion and withdrawal of the rigid pipe section 17. Normally, the cooling pipe 7 is located near the center of the circulation pipe 6. However, after the second drive unit 19 contracts, the cooling pipe 7 moves closer to the center of the circulation pipe 6, i.e., towards the soldering head 5. The folds 16, being elastic, are compressed during this process, allowing the cooling pipe 7 to fit more closely to the side of the circulation pipe 6 closest to the center. This reduces the distance between the cooling pipe 7 and the soldering head 5, thus reducing the thickness of the heat-conducting medium between them during cooling.

[0057] When cooling is not required, the length of the cooling pipe 7 in the circulation pipe 6 is restored, and the cooling pipe 7 will return to the center position under the elastic action of the pleats 16.

[0058] Example 3

[0059] The difference from the above embodiment is that a distance sensor 28 is provided at the end of the mounting base 2 away from the locking bracket 21. The distance sensor 28 is a laser distance sensor 28. The abutment plate 15 is slidably connected to the base 1, and a locking bolt 29 is slidably connected to the abutment plate 15. The base 1 is provided with a plurality of locking buckles 30.

[0060] The distance sensor 28 can detect the distance between the mounting base 2 and the metallized film capacitor, facilitating precise control of the distance between the welding electrodes 5 at both ends of the capacitor and the center of the capacitor body during welding. The abutment 15 can be adjusted in position by sliding, so as to adjust the pump momentum or trigger point for a single operation.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
