Description

Technical Field

[0001] This invention relates to the field of transformer coil processing technology, specifically to a soldering machine for processing transformer coils. Background Technology

[0002] The soldering machine for transformer coil processing is an automated equipment specifically designed for welding transformer coils. Its design must meet the high requirements of transformer coils for welding precision, efficiency and reliability. If the wire ends of the transformer coil are not properly treated, they are prone to high contact resistance, which leads to a large voltage drop when current passes through, resulting in power loss. In addition, they are prone to oxidation reaction with oxygen in the air.

[0003] Existing transformer coil soldering machines do not effectively position the coil ends during soldering, which can easily lead to uneven soldering at the coil ends and affect the efficiency of protecting the coil ends. At the same time, when soldering the gaps between different coil ends, oxygen in the air can oxidize the residual molten solder at the soldering machine nozzle, which can easily cause blockage at the soldering machine nozzle. Summary of the Invention

[0004] The technical problem solved by this solution is:

[0005] How to solve the problem that when soldering the coil wire ends, if the wire ends are not effectively positioned, uneven soldering at the coil wire ends can easily occur, affecting the protection efficiency of the coil wire ends;

[0006] When soldering the gaps between different coil wire ends, oxygen in the air can oxidize the residual solder at the soldering machine nozzle, easily causing blockage at the soldering machine nozzle.

[0007] The objective of this invention can be achieved through the following technical solution: a soldering machine for processing transformer coils, comprising a workbench and a housing fixedly installed on its top, a first cylinder arranged longitudinally fixedly installed on the top of the housing, a nozzle for discharging molten solder fixedly installed at the extended end of the first cylinder, an anti-oxidation mechanism for preventing the nozzle from clogging is provided inside the housing, and a conveying mechanism for conveying the coil is provided on one side of the anti-oxidation mechanism.

[0008] The anti-oxidation mechanism includes a mounting cover fixedly connected to the workbench. The mounting cover has a vent on the side facing the conveying mechanism, and a positioning unit for pressing the coil wire end is provided on one side of the vent.

[0009] A further technical improvement of the present invention is that: a flip plate is rotatably connected to the back of the inner wall of the outer shell, and the extended end of the first cylinder is movably connected to one end of the flip plate through a first lever.

[0010] A further technical improvement of the present invention is that: the positioning unit includes a guide frame fixedly connected to the top side of the mounting cover, a square rod is movably inserted on the guide frame, the square rod is arranged longitudinally, and the top of the square rod is movably connected to the middle of the flip plate through a second lever.

[0011] A further technical improvement of the present invention is that: an L-shaped plate is rotatably provided on the inner wall of the outer shell via a rotating shaft, one end of the L-shaped plate movably passes through a vent, and a pressing block is fixedly installed at its bottom; a roller is rotatably connected to the bottom of the square rod, and the position of the roller corresponds to the position of the L-shaped plate.

[0012] A further technical improvement of the present invention is that a fixing plate is fixedly installed on the inner side wall of the mounting cover, and a tension spring is fixedly connected between the fixing plate and the L-shaped plate, and the output end of the nozzle moves through the mounting cover.

[0013] A further technical improvement of the present invention is that: a positioning seat is fixedly provided inside the mounting cover, and a positioning groove for placing the coil wire end is opened on the top of the positioning seat. The position of the positioning groove corresponds to the position of the pressing block. During the extension of the extended end of the first cylinder, the flip plate drives the second lever and the square rod to move downward, so that the roller provides rolling pressure to the L-shaped plate. By rotating the L-shaped plate, it avoids obstructing the downward movement of the output end of the nozzle. At the same time, the pressing block provides pressure to the coil wire end located in the positioning groove, so that it is in close contact with the bottom of the inner wall of the positioning groove, which plays a role in positioning the coil wire end, avoiding uneven soldering at the coil wire end, and preventing the protection efficiency at the coil wire end from being affected.

[0014] A further technical improvement of the present invention is that: the conveying mechanism includes a fixed seat fixedly disposed on one side of the top of the workbench, a second cylinder is fixedly inserted inside the fixed seat, the second cylinder is arranged horizontally, and a support seat is fixedly installed at the extended end of the second cylinder, and a slot for placing a coil is provided on the top of the support seat.

[0015] A further technical improvement of the present invention is that: a sliding groove is provided on the top of the workbench, a slider is slidably arranged inside the sliding groove, the top of the slider is fixedly connected to the bottom of the support base, and a baffle is fixedly installed on the side of the support base away from the second cylinder.

[0016] A further technical improvement of the present invention is that: the width of the baffle is the same as the width of the vent, and the height of the baffle is half the height of the vent; by opening the gas supply fixture, nitrogen is injected into the mounting cover along the air inlet pipe, and the nitrogen forces the air in the mounting cover out of the vent, reducing the oxygen content in the mounting cover, avoiding oxidation of the molten solder remaining at the output end of the nozzle, and preventing blockage of the nozzle; by controlling the extension end of the second cylinder to extend to its maximum length, the coil is conveyed to the processing station. At this time, the coil end is located in the positioning groove, and the baffle blocks the lower part of the vent. During the process of soldering the coil end through the nozzle, the air inlet pipe continuously injects nitrogen into the mounting cover. At the same time, due to the flipping plate being flipped, excess nitrogen will be discharged from the upper part of the vent. During this process, the nitrogen flow will pass over the coil end, which not only prevents oxidation of the solder joint of the coil end, but also rapidly cools it, facilitating faster soldering of the coil end.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In use, during the extension of the first cylinder's extended end, the flip plate drives the second lever and square rod to move downwards, causing the roller to provide rolling pressure to the L-shaped plate. The rotation of the L-shaped plate prevents it from obstructing the downward movement of the nozzle's output end. At the same time, the pressing block presses the coil wire end located in the positioning groove, making it tightly adhere to the bottom of the inner wall of the positioning groove, thus positioning the coil wire end and preventing uneven soldering at the coil wire end, which would affect the protection efficiency of the coil wire end.

[0019] In use, this invention involves activating the gas supply fixture to inject nitrogen into the mounting cover via the air inlet pipe. The nitrogen forces air out of the vent, reducing the oxygen content and preventing oxidation of residual molten solder at the nozzle output, thus preventing clogging. By controlling the extension of the second cylinder to its maximum length, the coil is conveyed to the processing station. At this point, the coil end is located in the positioning groove, and the baffle blocks the lower part of the vent. During the soldering of the coil end through the nozzle, nitrogen continuously flows into the mounting cover via the air inlet pipe. Simultaneously, the flipping plate rotates, causing excess nitrogen to escape from the upper part of the vent. During this process, the nitrogen flow passes over the coil end, preventing oxidation at the solder joint and rapidly cooling it, thus accelerating the soldering process. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 As shown, a soldering machine for processing transformer coils includes a workbench 4 and a housing 6 fixedly installed on its top. A first cylinder 1 arranged longitudinally is fixedly installed on the top of the housing 6. A nozzle 12 for discharging molten solder is fixedly installed at the extended end of the first cylinder 1. An anti-oxidation mechanism 8 for preventing the nozzle 12 from being blocked is provided inside the housing 6. A conveying mechanism 7 for conveying the coil is provided on one side of the anti-oxidation mechanism 8.

[0031] Please see Figure 2 and Figure 3As shown, the above-mentioned anti-oxidation mechanism 8 includes a mounting cover 82 fixedly connected to the workbench 4. The mounting cover 82 has a vent 83 on the side facing the conveying mechanism 7. A positioning unit 84 for pressing the coil wire end is provided on one side of the vent 83.

[0032] Please see Figure 3 As shown, a flip plate 85 is rotatably connected to the back of the inner wall of the outer shell 6, and the extended end of the first cylinder 1 is movably connected to one end of the flip plate 85 via a first lever 81.

[0033] Please see Figures 3-5 As shown, the positioning unit 84 includes a guide frame 842 fixedly connected to the top side of the mounting cover 82. A square rod 847 is movably inserted on the guide frame 842. The square rod 847 is arranged longitudinally, and the top of the square rod 847 is movably connected to the middle of the flip plate 85 through a second lever 841.

[0034] Please see Figure 4 and Figure 5 As shown, an L-shaped plate 845 is rotatably mounted on the inner wall of the outer shell 6 via a pivot. One end of the L-shaped plate 845 movably passes through the vent 83, and a pressing block 844 is fixedly installed at its bottom. A roller 846 is rotatably connected to the bottom of the square rod 847, and the position of the roller 846 corresponds to the position of the L-shaped plate 845.

[0035] Please see Figure 3 and Figure 4 As shown, a fixing plate 843 is fixedly installed on the inner wall of the mounting cover 82. A tension spring is fixedly connected between the fixing plate 843 and the L-shaped plate 845. The output end of the nozzle 12 moves through the mounting cover 82.

[0036] Please see Figure 2 , Figure 4 and Figure 7 As shown, a positioning seat 11 is fixedly installed inside the mounting cover 82. The top of the positioning seat 11 has a positioning groove 13 for placing the coil wire end. The position of the positioning groove 13 corresponds to the position of the pressing block 844. During the extension of the extended end of the first cylinder 1, the flip plate 85 drives the second lever 841 and the square rod 847 to move downward, so that the roller 846 provides rolling pressure to the L-shaped plate 845. By rotating the L-shaped plate 845, it is prevented from obstructing the downward movement of the output end of the nozzle 12. At the same time, the pressing block 844 provides pressure to the coil wire end located in the positioning groove 13, so that it is in close contact with the bottom of the inner wall of the positioning groove 13, which plays the role of positioning the coil wire end, avoiding uneven soldering at the coil wire end, and preventing the protection efficiency at the coil wire end from being affected.

[0037] Please see Figure 2 and Figure 6As shown, the aforementioned conveying mechanism 7 includes a fixed base 5 fixedly installed on one side of the top of the workbench 4. A second cylinder 74 is fixedly inserted inside the fixed base 5. The second cylinder 74 is arranged horizontally, and a support base 71 is fixedly installed on the extended end of the second cylinder 74. A slot 75 for placing coils is opened on the top of the support base 71.

[0038] Please see Figure 1 and Figure 6 As shown, the top of the workbench 4 is provided with a sliding groove, and a slider 73 is slidably arranged inside the sliding groove. The top of the slider 73 is fixedly connected to the bottom of the support base 71, and a baffle 72 is fixedly installed on the side of the support base 71 away from the second cylinder 74.

[0039] Please see Figure 2 and Figure 6 As shown, the width of the baffle 72 is the same as the width of the vent 83, and the height of the baffle 72 is half the height of the vent 83. By opening the air supply fixture 3, nitrogen gas is injected into the mounting cover 82 along the air inlet pipe 10. The nitrogen gas forces the air in the mounting cover 82 out of the vent 83, reducing the oxygen content in the mounting cover 82 and preventing oxidation of the molten solder remaining at the output end of the nozzle 12, thus preventing blockage of the nozzle 12. By controlling the extension end of the second cylinder 74 to extend to its maximum length, the coil is transmitted to the processing... At this point, the coil wire end is located in the positioning groove 13. The baffle 72 blocks the lower part of the vent 83. During the process of soldering the coil wire end through the nozzle 12, the air inlet pipe 10 continuously injects nitrogen into the mounting cover 82. At the same time, due to the flipping plate 85 being flipped, excess nitrogen will be discharged from the upper part of the vent 83. During this process, the nitrogen gas flow will pass through the coil wire end, which not only prevents oxidation of the solder joint of the coil wire end, but also cools it quickly, which facilitates the speed of soldering the coil wire end.

[0040] Please see Figure 1 and Figure 6 As shown, the outer casing 6 has an opening at the bottom side near the fixed base 5, and the extended end of the second cylinder 74 moves through the interior of the opening.

[0041] Please see Figure 1 and Figure 2 As shown, a gas supply fixture 3 for conveying nitrogen is fixedly installed on the other side of the top of the workbench 4. The output end of the gas supply fixture 3 is connected to the input end of the air inlet pipe 10. The gas supply fixture 3 is existing technology, and a feeding fixture 2 for conveying molten tin is installed on the top of the gas supply fixture 3.

[0042] Please see Figure 2 As shown, the input end of the above-mentioned nozzle 12 is fixedly connected to the feed pipe 9, the feeding fixture 2 is the prior art, and the output end of the feeding fixture 2 is connected to the input end of the feed pipe 9.

[0043] Working principle: When using this invention, firstly, as... Figure 1 and Figure 6 As shown, the extended end of the second cylinder 74 is retracted to its shortest length, so that the support base 71 is located at the opening of the outer casing 6, facilitating the placement of the coil onto the slot 75 by the external feeding equipment. At this time, as... Figure 2 and Figure 3 As shown, the gas supply device 3 is turned on, allowing nitrogen gas to be injected into the mounting cover 82 along the air inlet pipe 10. The nitrogen gas forces the air inside the mounting cover 82 out through the vent 83, reducing the oxygen content inside the mounting cover 82 and preventing oxidation of the molten solder remaining at the output end of the nozzle 12, thus preventing blockage of the nozzle 12; Figure 3 , Figure 6 and Figure 7 As shown, by controlling the extension end of the second cylinder 74 to extend to its maximum length, the coil is conveyed to the processing station. At this time, the coil end is located in the positioning groove 13, and the baffle 72 blocks the lower part of the vent 83. During the process of soldering the coil end through the nozzle 12, the air inlet pipe 10 continuously injects nitrogen into the mounting cover 82. At the same time, due to the flipping plate 85 being flipped, excess nitrogen will be discharged from the upper part of the vent 83. During this process, the nitrogen flow will pass over the coil end, which not only prevents oxidation of the solder joint of the coil end but also rapidly cools it, facilitating faster soldering of the coil end. During the extension of the extension end of the first cylinder 1, as... Figure 3 , Figure 4 and Figure 7 As shown, the flip plate 85 drives the second lever 841 and the square lever 847 to move downwards, causing the roller 846 to provide rolling pressure on the L-shaped plate 845. The rotation of the L-shaped plate 845 prevents it from obstructing the downward movement of the nozzle 12's output end. Simultaneously, the pressing block 844 presses the coil wire end located in the positioning groove 13, ensuring it is tightly against the bottom of the inner wall of the positioning groove 13, thus positioning the coil wire end and preventing uneven soldering at the coil wire end, which would affect the protection efficiency at the coil wire end. Figure 3 and Figure 4 As shown, as the extended end of the first cylinder 1 continues to extend to its longest length, the nozzle 12 continues to move downward. At this time, the roller 846 rolls downward on the L-shaped plate 845, the L-shaped plate 845 does not rotate, and the position of the pressing block 844 does not change.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
