Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding cooling, in particular to an automatic welding and cooling device for metallized film capacitors. BACKGROUND

[0002] A metallized film capacitor is a capacitor made of an organic plastic film as a dielectric and a metallized film as an electrode, and is made by winding (except for a laminated structure), and has excellent electrical characteristics, high stability, long life, and other advantages, and can meet various different applications.

[0003] A conventional automatic welding device locks a welding electrode head by a mounting seat and a welding electrode locking head, and moves the welding electrode head by a sliding mounting seat to make the welding electrode head contact the metallized film capacitor, and the cooling structure is integrated in the sliding mounting seat and can cool the bottom of the welding electrode head by circulating cooling liquid.

[0004] During welding, the welding electrode head generates significant heat and becomes hot due to a large current, and in the conventional cooling method, only the bottom of the welding electrode head is in contact with the mounting seat with cooling characteristics, that is, only one surface is effectively cooled, and the remaining parts of the welding head are not effectively cooled. In long-term uninterrupted operation, the temperature of the welding head is high, the conductivity is reduced, the core material of the metallized film capacitor is damaged at high temperature, and the probability of virtual welding of the welding head increases, resulting in a significant increase in electrical performance problems of the capacitor product after welding.

[0005] In the conventional automatic welding device for metallized film capacitors, the welding electrode head is installed by open adjustment, and the front and rear positions of the welding electrode head are adjusted manually without support to meet the use requirements of the distance between the welding heads on both sides of the capacitor and the center of the capacitor body, but in actual use, due to improper adjustment and deviation of the reference position accuracy, the distance between the welding heads on both sides of the capacitor and the center of the capacitor body deviates, thereby causing common welding defects such as "welding too heavy and too deep" and "virtual welding".

[0006] In the welding process of the metallized film capacitor, there are four welding points, and a wire needs to be welded on both sides of the capacitor body, and one wire has two welding points. Due to the temperature difference between the welding electrode heads, the welding conditions of the two welding points of the wire are different, and the wire is easily warped or deformed. SUMMARY

[0007] The present application provides an automatic welding and cooling device for metallized film capacitors to achieve temperature equalization and overheating cooling of the same-side welding electrode head through a wrapping type circulating pipeline.

[0008] The application realizes the technical scheme as follows: the automatic welding and cooling equipment for the metallized film capacitor comprises a base, a mounting seat slidably connected to the base, a first driving element arranged on the base and used for driving the mounting seat to slide, two mounting holes arranged side by side in the mounting seat, and a welding electrode head detachably connected to each mounting hole; A circulating pipeline is integrated into the side wall of each mounting hole, and the two mounting holes are within the range of action of the circulating pipeline; a cooling pipe is arranged in the circulating pipeline, and the two ends of the cooling pipe extend out of the circulating pipeline; a pump body is connected to the cooling pipe and used for injecting cooling liquid into the cooling pipe; and a heat conduction agent is filled between the circulating pipeline and the cooling pipe. A pump chamber is fixedly connected to one side of the mounting seat, the pump chamber is provided with a first one-way valve and a second one-way valve, the directions of the first one-way valve and the second one-way valve are opposite, the first one-way valve and the second one-way valve are respectively connected to the circulating pipeline, a piston plate is arranged in the pump chamber, an elastic element is arranged between the piston plate and the inner side wall of the pump chamber, a push rod is fixedly connected to the end of the piston plate away from the elastic element, and a stop plate is arranged on one side of the base and extends to the stroke range of the push rod.

[0009] Further, a plurality of corrugations are arranged on the outside of the cooling pipe.

[0010] Further, the corrugations are elastic sheets, hard pipe segments are arranged at the two ends of the cooling pipe and extend out of the circulating pipeline, sealing washers are arranged at the positions where the hard pipe segments extend out of the circulating pipeline, and a second driving element is arranged on the mounting seat and used for driving the hard pipe segments to extend into or out of the circulating pipeline.

[0011] Further, a height adjusting frame is arranged at the bottom of the mounting seat and used for adjusting the height of the mounting hole.

[0012] Further, a locking support is fixedly connected to one side of the mounting seat, a tailstock is fixedly connected to the end of the locking support away from the mounting seat, a threaded hole is arranged on the tailstock, a threaded column is threadedly connected to the threaded hole, and the threaded column is used for being inserted into the mounting hole by rotating.

[0013] Further, a heat insulation block is fixedly connected to the end of the threaded column close to the mounting seat.

[0014] Further, a rotating disc is fixedly connected to the end of the threaded column away from the mounting seat.

[0015] Further, a positioning clamping block is arranged on the side of the mounting seat away from the locking support, the clamping block extends into the mounting hole, and a ladder-shaped groove is arranged on the side of the positioning clamping block close to the mounting hole.

[0016] Further, a distance sensor is arranged on the end of the mounting seat away from the locking support.

[0017] Further, the stop plate is slidably connected to the base, a lock bolt is slidably connected to the stop plate, and a plurality of lock buckles are arranged on the base.

[0018] The technical scheme of the present application has at least the following beneficial effects: When the metalized film capacitor is welded, welding leads are needed to be welded on both sides of the metalized film capacitor. Each welding lead has two welding points. Therefore, two mounting holes are provided on the mounting seat to mount the welding electrode heads, so that the first driving member drives the mounting seat to approach the metalized film capacitor to weld the two welding points. By providing welding equipment on both sides of the metalized film capacitor, the welding of four welding points can be simultaneously performed.

[0019] The mounting seat is mounted with the welding electrode heads through the mounting holes, so that the circulating pipeline is integrated in the mounting seat and can wrap the welding electrode heads in all directions, so that the welding electrode heads can be affected in all directions when being cooled, which is better than the bottom cooling in the prior art and the heat transfer is more uniform.

[0020] Since the two welding electrode heads contact the welding lead at the same time during welding, if the temperature difference between the two welding electrode heads is large, the melting or solidification speed of one welding point will be faster than that of the other, which can easily cause the welding lead to be raised or deformed. Therefore, the circulating pipeline is internally provided with a cooling pipe, and a heat conduction agent is filled between the circulating pipeline and the cooling pipe. The heat conduction agent can effectively conduct the temperature of the welding electrode heads and make the two welding electrode heads in the mounting seat conduct heat to each other through the temperature conduction capacity thereof, thereby reducing the temperature difference between the welding electrode heads.

[0021] Since the cooling pipe only injects liquid when cooling is needed, if it acts on the welding electrode heads for a long time, it can affect the normal temperature rise of the welding electrode heads, and the boiling point of the cooling liquid is 100-160℃, which does not match the temperature of the welding electrode heads during welding, and cannot balance the temperature of the two welding electrode heads. Therefore, the cooling pipe is internally provided in the circulating pipeline, so that the covering coverage of the cooling pipe is the same as that of the circulating pipeline, and the two do not occupy each other's positions and affect the coverage. The cooling pipe is connected to the pump body, so that it can inject and circulate the cooling liquid through the pump body. The cooling liquid will first be conducted to the heat conduction agent to cool the heat conduction agent, and then the heat conduction agent will cool the two welding electrode heads.

[0022] During the welding operation, the first driving member will continuously drive the mounting seat to approach and then move away from the metalized film capacitor. Therefore, the pump chamber is provided, and the push rod of the pump chamber will abut against the abutting plate when the mounting seat approaches the metalized film capacitor, so that the piston plate is pushed and the space in the pump chamber is compressed, and the heat conduction agent in the pump chamber is squeezed out from the first one-way valve. When the mounting seat moves away from the metalized film capacitor, the elastic member will open the piston plate to expand the space in the pump chamber, and the pump chamber will absorb the heat conduction agent through the second one-way valve. In this way, as long as the first driving member operates, the heat conduction agent will be continuously circulated through the pump chamber, so that the heat conduction agent is always circulated and does not need an additional pump to drive.

[0023] Compared with the prior art, the scheme adopts a wrapped circulating pipeline, which can effectively improve the heat exchange performance of the electrode tip. Through the built-in cooling pipe and the setting of the pump chamber, the displacement of the first driving member during the welding action is used to make the circulating pipeline have the functions of reducing the temperature difference between the two electrode tips and cooling the electrode tip.

[0029] The following detailed description illustrates the specific implementation method: Example 1 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.

[0030] 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.

[0031] The mounting base 2 is bolted on one side with a pump chamber 9, the pump chamber 9 is provided with a first one-way valve 10 and a second one-way valve 11, the directions of the first one-way valve 10 and the second one-way valve 11 are opposite, the first one-way valve 10 and the second one-way valve 11 are respectively communicated with the circulating pipeline 6, in the embodiment, the circulating pipeline 6 is disconnected from the middle into two sections, the first one-way valve 10 and the second one-way valve 11 are respectively communicated with the two sections of the circulating pipeline 6, so that the first one-way valve 10 and the second one-way valve 11 can be more concentrated, the pump chamber 9 is provided with a piston plate 12, the piston plate 12 and the inner wall of the pump chamber 9 are provided with an elastic element 13, the end of the piston plate 12 away from the elastic element 13 is fixedly connected with a push rod 14, one side of the base 1 is provided with an abutting plate 15, the abutting plate 15 extends to the stroke range of the push rod 14.

[0032] The mounting base 2 is bolted on one side with a lock bracket 21, the end of the lock bracket 21 away from the mounting base 2 is welded with a tail seat 22, the tail seat 22 is provided with a threaded hole 23, the threaded hole 23 is threadedly connected with a threaded column 24, the threaded column 24 is used to be inserted into the mounting hole 4 by rotating. The end of the threaded column 24 close to the mounting base 2 is bolted with a heat insulation block. The end of the threaded column 24 away from the mounting base 2 is bolted with a rotating disc 25.

[0033] The mounting base 2 is provided with a positioning clamping block 26 away from the lock bracket 21, the clamping block extends into the mounting hole 4, the side of the positioning clamping block 26 close to the mounting hole 4 is provided with a ladder groove 27.

[0034] When the metalized film capacitor is welded, it needs to be welded with welding leads on both sides, and each welding lead has two welding points. Therefore, the mounting base 2 is provided with two mounting holes 4 for mounting the welding electrode heads 5, so that the first driving element 3 drives the mounting base 2 to move close to the metalized film capacitor to weld two welding points. By setting welding equipment on both sides of the metalized film capacitor, four welding points can be welded at the same time.

[0035] In use, the height of the mounting hole 4 can be adjusted by the height adjusting frame 20, so that the height of the mounting hole 4 is flush with the area to be welded. Since the two welding electrode heads 5 are installed in the mounting hole 4, the integrated design of the mounting base 2 can keep the two welding electrode heads 5 consistent in height, effectively avoiding the abnormal installation state of the welding electrode heads 5 on the same side.

[0036] When installing, the electrode tip 5 is inserted into the installation hole 4, ensuring that each contact surface of the electrode tip 5 is in close contact with the side wall of the installation hole 4, and the threaded column 24 is rotated by the rotating disc 25, and the threaded column 24 will be inserted into the installation hole 4 under the action of rotation, and the electrode tip 5 is pushed into the installation hole 4. Since the other end of the mounting seat 2 is provided with a positioning block 26, when the electrode tip 5 abuts against the positioning block 26, it means that the electrode tip 5 is in place. The ladder groove 27 on the positioning block 26 can keep the electrode tip 5 slightly protruding from the mounting seat 2. Since the welding wire also has a thickness, as long as the thickness of the positioning block 26 is less than the thickness of the welding wire, the contact between the electrode tip 5 and the welding wire can be ensured.

[0037] The mounting seat 2 is installed through the installation hole 4, and the circulating pipe 6 is integrated in the mounting seat 2, which can wrap the electrode tip 5 in all directions, so that the electrode tip 5 can be cooled in all directions when cooled. Compared with the prior art, the cooling effect is better and the heat control is more uniform.

[0038] Since two electrode tips 5 contact the welding wire at the same time during welding, if the temperature difference between the two electrode tips 5 is large, the melting or solidification speed of one welding point will be faster than the other, which can easily cause the welding wire to be raised or deformed. Therefore, the circulating pipe 6 is provided with a cooling pipe 7, and the heat conduction agent 8 is filled between the circulating pipe 6 and the cooling pipe 7. The heat conduction agent 8 can effectively conduct the temperature of the electrode tip 5, and through its temperature conduction capacity, the two electrode tips 5 in the mounting seat 2 can be heat-conducted to each other, reducing the temperature difference between the electrode tips 5.

[0039] Since the cooling pipe 7 only injects liquid when cooling is needed, if it acts on the electrode tip 5 for a long time, it will affect the normal heating of the electrode tip 5, and the boiling point of the cooling liquid is 100-160℃, which does not match the temperature of the electrode tip 5 during welding, and cannot balance the temperature of the two electrode tips 5. Therefore, the cooling pipe 7 is built-in in the circulating pipe 6, so that the covering coverage of the cooling pipe 7 is the same as that of the circulating pipe 6, and they do not occupy each other's position and affect the coverage. The cooling pipe 7 is connected to the pump body, so that it can inject and circulate the cooling liquid through the pump body. The cooling liquid is first conducted to the heat conduction agent 8 to cool the heat conduction agent 8, and then the heat conduction agent 8 is used to cool the two electrode tips 5. Since the cooling liquid and the heat conduction agent 8 are both liquids, they can be combined with the special-shaped contact surface through their flowability, so that the wrinkle 16 can be set to increase the heat exchange performance of the cooling liquid and the heat conduction agent 8, so that the cooling liquid can quickly take away the temperature of the heat conduction agent 8.

[0040] When the welding operation is performed, the first driving member 3 will continuously drive the mounting seat 2 to approach and then leave the metallized film capacitor, so the pump chamber 9 is arranged, the push rod 14 of the pump chamber 9 will abut against the abutting plate 15 when the mounting seat 2 approaches the metallized film capacitor, so that the piston plate 12 is pushed, the space in the pump chamber 9 is compressed, and the heat conducting agent 8 in the pump chamber 9 is extruded out from the first one-way valve 10. When the mounting seat 2 is away from the metallized film capacitor, the elastic member 13 will push open the piston plate 12, the space in the pump chamber 9 is expanded, the pump chamber 9 will absorb the heat conducting agent 8 through the second one-way valve 11, and through one suction and one discharge, the heat conducting agent 8 can be kept flowing. As long as the first driving member 3 operates, the heat conducting agent 8 will be continuously circulated through the pump chamber 9, so that the heat conducting agent 8 is always kept circulating and does not need an additional pump for driving.

[0041] Embodiment 2 The difference from the above-mentioned embodiments is that the wrinkle 16 is an elastic sheet, the cooling pipe 7 is provided with a hard pipe segment 17 at both ends, the hard pipe segment 17 extends out of the circulating pipe 6, the hard pipe segment 17 is provided with a sealing washer 18 at the position extending out of the circulating pipe 6, the mounting seat 2 is provided with a second driving member 19 for driving the hard pipe segment 17 to probe into and pull out of the circulating pipe 6, and the second driving member 19 is a pneumatic cylinder, the output shaft of the pneumatic cylinder is fixedly connected with the hard pipe.

[0042] Although the cooling pipe 7 can achieve the cooling of the electrode tip 5 by changing the temperature of the heat conducting agent 8, the cooling pipe 7 is always spaced apart from the heat conducting agent 8, and the response speed of the conduction is slow. Since the heat conducting agent 8 is a fluid, the cooling pipe 7 can move and change the position of the heat conducting agent 8. When the cooling is performed, the second driving member 19 will adjust the length of the cooling pipe 7 in the circulating pipe 6 by adjusting the probe-in and pull-out of the hard pipe segment 17. In the normal state, the cooling pipe 7 is close to the central position in the circulating pipe 6, and after being contracted by the second driving member 19, the cooling pipe 7 will be close to the surrounding center of the circulating pipe 6, that is, close to the electrode tip 5. The wrinkle 16 can be extruded by the process due to the elasticity, so that the cooling pipe 7 can be more close to the side of the circulating pipe 6 close to the surrounding center, so that the distance from the cooling pipe 7 to the electrode tip 5 can be reduced, and the thickness of the heat conducting medium between the cooling pipe 7 and the electrode tip 5 during the cooling can be reduced.

[0043] When the cooling is not needed, the length of the cooling pipe 7 in the circulating pipe 6 is restored, and the cooling pipe 7 will return to the central position under the elastic action of the wrinkle 16.

[0044] Embodiment 3 The difference from the above-mentioned embodiments is that the mounting seat 2 is provided with a distance sensor 28 at the end away from the locking support 21, and the distance sensor 28 is a laser distance sensor 28. The abutting plate 15 is in sliding connection with the base 1, the abutting plate 15 is in sliding connection with a lock bolt 29, and the base 1 is provided with a plurality of lock buckles 30.

[0045] The distance sensor 28 can detect the distance between the mounting seat 2 and the metallized film capacitor, so as to realize accurate control of the distance between the two end electrode heads 5 of the capacitor and the center of the capacitor body during welding. The stop plate 15 can be adjusted in position by sliding, so as to adjust the single pumping amount or trigger node.

[0046] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
