Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to welding equipment and a welding process for producing micro transformers. Background Art

[0002] Micro transformers are widely used in communication equipment, consumer electronics, medical equipment and other fields, especially in situations where high-frequency, efficient power conversion and signal transmission are required. They are characterized by small transformer size, low cost, and less wire usage. The load rate and utilization rate of micro transformers are generally low.

[0003] Micro-transformers usually require large-scale welding production, so micro-transformers usually need to be conveyed during welding to increase the production speed of micro-transformers. For example, the Chinese patent with publication number CN118635749A in the relevant technology proposes an automatic welding device for transformers, which has the advantages of placing the unwelded transformer shell on a belt conveyor and loading materials through two loading boxes on both sides thereof, so that both the main heat dissipation fins and the side heat dissipation fins can be welded to the transformer shell. Through the setting of the pushing mechanism, there is no need to specially position the transformer shell, loading and unloading are more convenient, and flow-type welding operations can be performed, which greatly improves the welding efficiency and improves the production efficiency of the transformer shell.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: in order to ensure the stability of the welding of the micro-transformer shell, it is usually necessary to weld multiple surfaces of the micro-transformer shell, but in the prior art, the micro-transformer shell is usually a hollow rectangular parallelepiped with missing faces, so that the welding equipment can usually only weld the outer surface plane of the micro-transformer shell, and it is not convenient to control the welding device to weld the irregular inner curved surface and inner inclined surface of the micro-transformer shell. The staff needs to turn over and adjust the micro-transformer shell to achieve the purpose of welding the irregularly shaped micro-transformer shell by the welding device. This method is not only time-consuming and labor-intensive, but also increases the labor intensity of the staff, and limits the scope and effect of welding the micro-transformer shell by the welding equipment. Summary of the invention

[0005] In order to solve the problem that welding equipment can usually only weld the outer surface plane of the micro transformer shell, and it is not convenient to control the welding device to weld the inner curved surface and inner inclined surface of the irregularly shaped micro transformer shell, and the staff needs to turn over and adjust the micro transformer shell to achieve the purpose of welding the irregularly shaped micro transformer shell with the welding device on multiple sides, the present application provides a welding device and a welding process for micro transformer production.

[0006] The present application provides a welding device and welding process for producing a micro transformer, which adopts the following technical solutions: A welding device for producing a micro transformer, comprising a welding frame, a conveying box fixed on the welding frame, a plurality of support plates arranged on the welding frame, each of the support plates being provided with two micro transformer shells, a welder for welding the two micro transformer shells, and a buffer for lifting and lowering the welder; Each of the support plates is provided with an adjustment component for turning over and translating the two micro-transformer shells, and the welding frame is provided with a driving component for driving the adjustment component, a painting component for painting the two micro-transformer shells, and a fixing component for automatically fixing the support plate; The conveying box is provided with a conveying assembly for conveying a plurality of support plates, and the conveying assembly comprises a conveying platform movably arranged on the welding frame and a conveying member for driving the conveying platform; The adjustment assembly includes a flipping member, a translation member, a U-shaped frame movably arranged on the support plate, two support shafts and two limit frames rotatably arranged on the U-shaped frame, a limit member for limiting the support shaft, a clamping member for clamping two micro-transformer shells, and an adjustment member for adjusting the limit frame; The buffer member comprises an electric push rod fixed on the welding frame, a fixing box fixed on the electric push rod, an annular spring fixed in the fixing box, and a buffer rod fixed on the annular spring, wherein the buffer rod is fixedly connected to the welding device; The paint spraying parts include a first dye box and a second dye box fixed on a welding frame, a first feed pump and a first hose fixed on the first dye box, a second feed pump and a second hose fixed on the second dye box, and a fixed block fixed on a welder. The outlet ends of the first hose and the second hose are fixedly connected to the fixed block, the output end of the first feed pump is connected to the first hose, and the output end of the second feed pump is connected to the second hose. The first dye box is used to store black insulating paint, and the second dye box is used to store red anti-corrosion paint.

[0007] By adopting the above technical solution, two micro transformer shells can be welded by a welder, and the welder can be driven to move up and down by a buffer, and the welder can have an up and down buffering effect, so that the welder can always fit the two micro transformer shells when the two micro transformer shells are swinging and translating, and there is no need to always adjust the fit between the welder and the two micro transformer shells by an electric push rod to ensure the welding accuracy of the two micro transformer shells. A plurality of two micro transformer shells that need to be welded can be transported by a conveying component to achieve the purpose of conveying and welding the micro transformer shells; Although the welding equipment in the prior art also has the advantage of welding the irregularly shaped curved and inclined surfaces of the micro transformer shell, it is usually achieved by a welding robot, because the welding robot can perform tight tilt movement and flat adjustment while welding the curved and inclined surfaces of the micro transformer shell. However, the use of welding robots to weld a large number of micro transformers has the problems of very high investment costs, high skill requirements for operators, and the need for the welding robot to be adjusted and optimized at any time. Moreover, the welding equipment is not convenient for painting and testing the micro transformer shell, so after the welding equipment completes the welding of a large number of micro transformer shells, the staff still needs to use a detector to test the welding parts of all micro transformers to detect whether there are welds at the welding parts of the micro transformers. If there are welds, it means that the welding quality of the micro transformer is unqualified. However, this detection method is not only slow, but also increases the labor intensity of the staff, because the staff will fall into a fatigue state after using the detector for a long time, which makes it easy to be negligent, miss detection or make mistakes, which cannot meet the efficiency and needs of the actual production of micro transformers; The turning piece and the translation piece in the adjustment component can be used to adjust the angle, translate and flip the two welded micro transformer shells to ensure the welding of the inner and outer inclined surfaces, curved surfaces and planes of the two micro transformer shells. At the same time, the double-sided welding of the two micro transformer shells can also be achieved to ensure the stability of the welding of the two micro transformer shells. The adjustment component can be driven by the driving piece. The two micro transformer shells being welded can be positioned by the fixing piece to prevent the two micro transformer shells from moving randomly during welding, translation and flipping. The two micro transformer shells can be clamped by the clamping piece to prevent the two micro transformer shells from falling off during welding. The two micro transformer shells can be closely attached together by the adjustment piece to prevent the two micro transformer shells from shifting during welding. The two micro transformer shells can be limited by the limiting piece to prevent the two micro transformer shells from shifting at an angle during transmission. At the same time, when the welder is welding the micro transformer shell, the paint spraying part will spray paint the micro transformer shell. The paint component can apply black insulating paint on the inner surface of the micro transformer shell to make the inner sides of the two micro transformer shells have an insulating effect. At the same time, the outer surface of the micro transformer shell can be painted red, so that the outer side of the micro transformer shell can be painted with red anti-corrosion paint to play a warning effect to ensure the usability of the micro transformer shell. The micro transformer shell can also be inspected by this method, because if there is a weld at the welding point of the micro transformer shell, the black paint and red paint on the inner and outer surfaces of the micro transformer shell will inevitably overlap. If the black paint on the inside of the micro transformer shell tends to be dark red or the red paint on the outer surface of the micro transformer shell If it is black, it means that the welding quality of the micro transformer shell is unqualified, otherwise it means that the quality is qualified. The staff can directly see whether the welding quality of the micro transformer shell is qualified through the color. This method is not only simple and fast, but also can cool the micro transformer shell during painting. The detection process, cooling process and painting process of the micro transformer shell can be combined together to improve the effect of the micro transformer shell welding production. Finally, after the micro transformer shell is fully welded and painted, the transmission component can continue to transmit the micro transformer shell, and the processed micro transformer shell can be discharged. At the same time, the micro transformer shell to be processed will be transmitted to the position to be welded. Such a cycle can achieve the purpose of batch welding production of micro transformer shells; The electric push rod can sequentially drive the fixing box, the annular spring, the buffer rod and the welder to move downward, so that the welder can fit the micro transformer shell, and then the two micro transformer shells can be welded by the welder, and the spring of the annular spring can make the welder have a buffering effect, so that when the two micro transformer shells are swinging and translating, the welder can always fit the two micro transformer shells by the elastic force of the annular spring, and there is no need to always adjust the fit of the welder and the two micro transformer shells by the electric push rod to ensure the welding accuracy of the two micro transformer shells, and there is no need to weld the two micro transformer shells by a welding robot, thereby saving the consumption cost of welding the micro transformer shells; When the welder is welding the inner sides of the two micro-transformer shells, the first pump will spray the black insulating paint on the inside of the first dye box onto the inner sides of the two micro-transformer shells through the first hose, so that the inner sides of the two micro-transformer shells have an insulating effect. When the welder is welding the outer sides of the two micro-transformer shells, the second pump will spray the red anti-corrosion paint on the inside of the second dye box onto the outer sides of the two micro-transformer shells through the second hose, so that the outer sides of the two micro-transformer shells have an anti-corrosion effect. By observing the color of the weld between the two micro-transformer shells, it is judged whether the weld of the two micro-transformer shells is qualified. When the color of the weld on the outer sides of the two micro-transformer shells tends to be black or dark red or the color of the weld on the inner sides of the two micro-transformer shells tends to be dark red or dark dark, it indicates that the weld quality of the two micro-transformer shells is unqualified.

When the conveying platform moves forward, the support plate will be pushed one grid, and when the conveying platform moves backward, it can be restored to its original position. The support plate with two micro-transformer shells can be placed on the conveying platform again, and then the conveying platform can simultaneously convey multiple support plates with two micro-transformer shells through this method. At the same time, multiple micro-transformer shells can be completely conveyed through this conveying method, and there is no need to use a conveyor to convey multiple micro-transformer shells, because the conveyor is prone to wear and damage to the conveyor belt due to gravity when conveying a large number of micro-transformer shells.

[0016] Optionally, the adjusting member comprises a connecting rod fixed on the supporting shaft, the inner side of the connecting rod is movably connected with a connecting square rod, the outer side of the connecting square rod is provided with four compression springs, the outer sides of the four compression springs are each provided with an arc block, the outer side of the connecting square rod is provided with four arc grooves, and the four arc blocks are respectively engaged with the four arc grooves; The clamping member includes two screw rods, two rotating blocks and two clamping blocks rotatably arranged on the U-shaped frame, the two limiting frames are respectively threadedly connected to the two screw rods, the two rotating blocks and the two clamping blocks are respectively fixedly connected to the two screw rods, the two clamping blocks and the two limiting frames are movably fitted with the micro-transformer shell, and the two limiting frames are respectively fixedly connected to the two connecting square rods.

When the four limit clamps rotate, they will fit with the support plate, so that the support plate can be clamped and fixed.

[0020] The second aspect of the present application provides a welding process for producing a micro transformer using the following technical solution: The embodiment of the present application also discloses a welding process for producing a micro transformer, based on the above-mentioned welding equipment for producing a micro transformer, comprising the following steps: S1. The clamping piece can clamp and fix the two welded micro transformer shells, the adjusting piece can fit the two micro transformer shells tightly together, and the limiting piece can position the two micro transformer shells. After the two micro transformer shells are fixed and the angles are adjusted, the two micro transformer shells are placed on the conveying table; S2. The conveying assembly can drive the conveying platform to move up and down and forward and backward, so that the conveying platform can simultaneously convey multiple micro transformer shells, and can convey two micro transformer shells to the bottom of the welder, and can also discharge the processed micro transformer shells, and can cyclically convey the micro transformer shells. When the two micro transformer shells are conveyed to the bottom of the welder, the fixing parts can limit the two micro transformer shells to be welded; S3. The electric push rod can drive the fixed box, the annular spring and the welder to move up and down in sequence. When the two micro transformer shells are swinging and translating, the elastic force of the annular spring can make the welder always fit with the two micro transformer shells to ensure the welding accuracy of the two micro transformer shells; S4. The driving member can drive the two micro-transformer shells to rotate counterclockwise, and the welder can perform arc welding on the side joints of the two micro-transformer shells. When the two micro-transformer shells are adjusted to a flat state, the driving member can drive the two micro-transformer shells to translate, and the welder can weld the plane joints of the two micro-transformer shells. Through the swing and translation of the two micro-transformer shells, the side, plane and side of the two micro-transformer shells can be welded in sequence. When the two micro-transformer shells are turned over, the two micro-transformer shells can continue to be swung and translated, and the welder can weld the side, plane and side of the outer side of the two micro-transformer shells in sequence, so as to achieve double-sided welding of the inner and outer sides of the two micro-transformer shells; S5. When the welder is welding the inner sides of the two micro-transformer shells, the spray paint part can spray black insulating paint on the inner sides of the two micro-transformer shells to make the inner sides of the two micro-transformer shells have an insulating effect. When the welder is welding the outer sides of the two micro-transformer shells, the spray paint part can spray red anti-corrosion paint on the outer sides of the two micro-transformer shells to make the outer sides of the two micro-transformer shells have an anti-corrosion effect. Observe the color of the welding point of the two micro-transformer shells to judge whether the welding point of the two micro-transformer shells is qualified; S6. When the color of the welding places on the outer sides of the two micro-transformer shells tends to be dark red or the color of the welding places on the inner sides of the two micro-transformer shells tends to be dark dark, the welding quality of the two micro-transformer shells is unqualified. On the contrary, if the welding places on the outer sides of the two micro-transformer shells are all red and the welding places on the inner sides of the two micro-transformer shells are all black, it means that there are no welds at the welding places of the two micro-transformer shells, indicating that the welding quality of the two micro-transformer shells is qualified.

[0021] By adopting the above technical scheme, the welder can be controlled to weld the inner curved surface and inner inclined surface of the irregularly shaped micro transformer shell, and the staff does not need to turn over and adjust the micro transformer shell, so as to achieve the purpose of welding the irregularly shaped micro transformer shell with the welding device on multiple surfaces. The micro transformer shell can be spray-painted and tested. After a large number of micro transformer shells are welded, the welding quality of the micro transformer shell can be detected by observing the color of the inner and outer welding points of the micro transformer shell. The detection method is very fast and convenient. A large number of micro transformer shells can be welded without using a welding robot, which can save the welding cost of the micro transformer shell. The purpose of welding the inner and outer curved surfaces, inclined surfaces and flat surfaces of the micro transformer shell can be achieved by using an ordinary welder, and the speed and accuracy of welding a large number of micro transformer shells can be guaranteed.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The two micro transformer shells to be welded can be clamped and fixed by the clamping piece to avoid shaking or deviation of the two micro transformer shells during welding or rotation. The two micro transformer shells can be closely fitted together by the adjusting piece to avoid separation of the two micro transformer shells during welding. The two support shafts and the two micro transformer shells can be positioned by the limiter, and the two micro transformer shells can be kept at the current angle for transmission to avoid the angle deviation of the two micro transformer shells during transmission. The two micro transformer shells can be rotated by the rotation of external force to realize the subsequent rotation welding of the two micro transformer shells. After the two micro transformer shells are fixed and the angle is adjusted, the support plate with the two micro transformer shells can be placed on the conveying table; 2. The servo motor can sequentially drive the driving wheel, the conveyor belt, the driven wheel, the two first gears, the two second gears, the two third gears and the two fourth gears to rotate, and then drive the two first brackets, the two second brackets and the conveying platform to move up and down and forward and backward. Then, through this method, the conveying platform can simultaneously convey multiple support plates with two micro-transformer shells, and can convey the two micro-transformer shells to the bottom of the welder. At the same time, the processed micro-transformer shells can be discharged, and the micro-transformer shells to be processed can also be transferred to the position to be welded. Such a cycle can achieve the purpose of batch welding production of micro-transformer shells; 3. When the support plate with two micro transformer shells is transferred to the bottom of the welder, the four fixed racks will mesh with the four limit gears respectively through the gravity of the support plate falling, and then drive the four limit gears and the four limit clamps to rotate at an angle respectively. When the four limit clamps rotate, they will fit with the support plate, so that the support plate can be clamped and fixed to avoid the deviation of the support plate when the two micro transformer shells are welded, so as to ensure the welding and fixing effect of the two micro transformer shells. At the same time, the two transmission gears will mesh with the two movable gears respectively, and the two first bevel gears will mesh with the two second bevel gears respectively; 4. The electric push rod can sequentially drive the fixing box, the annular spring, the buffer rod and the welder to move downward, and the welder can be moved to the starting position where the two micro transformer shells fit together. The welder can be used to weld the two micro transformer shells, so that the annular spring is in a compressed state, and the spring of the annular spring can make the welder have a buffering effect, so that when the two micro transformer shells are swinging and translating, the elastic force of the annular spring can make the welder always fit the two micro transformer shells, and there is no need to use the electric push rod to always adjust the fit between the welder and the two micro transformer shells, so as to ensure the accuracy and effect of the welding of the two micro transformer shells; 5. The motor can sequentially drive the two driving wheels, the two first conveyor belts, the two double-belt pulleys, the two second conveyor belts, the two follower wheels, the two movable gears and the two connecting gears to rotate clockwise. Through the connection and cooperation between the second inner ratchet, the two first clamping blocks, the two first springs and the movable pin, when the movable gear rotates clockwise, the two first bevel gears will not rotate, and only the two first clamping blocks will slide on the inner side of the second inner ratchet. Because the two transmission gears are respectively engaged with the two movable gears, when the two connecting gears rotate clockwise, they will respectively drive the two transmission gears, the two supporting shafts, the two connecting rods, the two connecting square rods, the two limit frames and the two micro transformer shells to rotate counterclockwise. When the transformer shell rotates counterclockwise, the welder can perform swing welding on the joints of the two micro-transformer shells, and can weld the joints of the inner sides of the two micro-transformer shells. When the two micro-transformer shells are adjusted to a flat state, the two driving wheels, the two first conveyor belts, the two double pulleys, the two second conveyor belts, the two follower wheels, the two movable gears, the two connecting gears, the two second inner ratchets and the two first bevel gears can be driven in sequence by the motor to rotate counterclockwise, thereby driving the two transmission gears and the two first inner ratchets to rotate clockwise. Through the connection and cooperation between the first inner ratchet, the two second blocks, the two second springs and the short pin, the two supporting shafts can not rotate when the two first inner ratchets rotate clockwise. , will only make the two second blocks slide on the inner side of the first inner ratchet, and then respectively drive the two second bevel gears and the two bidirectional screws to rotate clockwise, and then in turn drive the two threaded blocks, the U-shaped frame, the two supporting shafts, the two transmission gears, the two connecting rods, the two connecting square rods, the two limit frames and the two micro-transformer shells to translate forward, and the welder can be used to weld the joints of the internal planes of the two micro-transformer shells, and at the same time, the two transmission gears will be meshed with the two connecting gears respectively. At this time, the two connecting gears can respectively drive the two transmission gears to rotate counterclockwise, and then drive the two micro-transformer shells to rotate counterclockwise, and then the swing and translation of the two micro-transformer shells can be controlled by this method. The side, plane and side of the part are completely welded in sequence, which can ensure the welding effect of the internal joint of the two micro-transformer shells. After the internal welding of the two micro-transformer shells is completed, the two micro-transformer shells are swung continuously, and the two micro-transformer shells can be turned over, so that the outer sides of the two micro-transformer shells face upward, and then the two micro-transformer shells are swung and translated. The side, plane and side of the outer side of the two micro-transformer shells can be completely welded in sequence by the welder, which can ensure the welding effect of the external joint of the two micro-transformer shells. The two micro-transformer shells can be welded together by this method, and the stability of the welding of the two micro-transformer shells can be ensured. 6. When the welder is welding the inner sides of the two micro-transformer shells, the first pump will spray the black insulating paint in the first dye box onto the inner sides of the two micro-transformer shells through the first hose, so that the inner sides of the two micro-transformer shells have an insulating effect, avoiding electric shock due to the components inside the micro-transformer when the micro-transformer is used later, so as to ensure the safety of the use of the micro-transformer. When the welder is welding the outer sides of the two micro-transformer shells, the second pump will spray the red anti-corrosion paint in the second dye box onto the outer sides of the two micro-transformer shells through the second hose, so that the outer sides of the two micro-transformer shells have an anti-corrosion effect. At the same time, applying red anti-corrosion paint on the outer sides of the micro-transformer shells can serve as a warning, which can serve as a reminder when the micro-transformer is in use. After the two micro-transformer shells are welded, the color of the welding point between the two micro-transformer shells can be observed. To judge whether the welding joints of the two micro-transformer shells are qualified. When the color of the welding joints on the outer sides of the two micro-transformer shells tends to black or dark red, or the color of the welding joints on the inner sides of the two micro-transformer shells tends to dark red or dark dark, it means that there are welds at the welding joints of the two micro-transformer shells, indicating that the welding quality of the two micro-transformer shells is unqualified. If the welding joints on the outer sides of the two micro-transformer shells are all red, and the welding joints on the inner sides of the two micro-transformer shells are all black, it means that there are no welds at the welding joints of the two micro-transformer shells, indicating that the welding quality of the two micro-transformer shells is qualified. The welding effect of the two micro-transformer shells can be detected, and the welding device can be controlled to weld the inner curved surface and inner inclined surface of the irregularly shaped micro-transformer shell. The micro-transformer shell can be painted and inspected. The welding quality of the micro-transformer shell can be detected by observing the color of the inner and outer welding joints of the micro-transformer shell.

[0037] The implementation principle of a welding device for producing a micro transformer in the embodiment of the present application is as follows: (1) The two miniature transformer shells 57 to be welded together are placed in the two limiting frames 34 respectively, and then the two rotating blocks 36 can be rotated to drive the two screw rods 35 and the two clamping blocks 37 to rotate respectively. Because the two screw rods 35 are respectively threadedly connected to the two limiting frames 34, the two screw rods 35 can respectively drive the two clamping blocks 37 to rotate up and down, so that the two clamping blocks 37 are respectively fitted with the two miniature transformer shells 57. With the cooperation of the two limiting frames 34, the two miniature transformer shells 57 can be clamped and fixed respectively, so as to avoid the two miniature transformer shells 57 from shaking or deflecting during welding or rotation. (2) After the two micro-transformer shells 57 are clamped, the two connecting square rods 33 are pulled relative to each other to fit the two micro-transformer shells 57 together, so that the four compression springs 38 on the inner sides of the two connecting rods 32 are all in a compressed state. When the two micro-transformer shells 57 are fitted together, the four arc grooves on the outer sides of the two connecting square rods 33 will correspond to the four arc blocks 39 on the inner sides of the two connecting rods 32 respectively. At this time, the arc blocks 39 can be pushed to the inner sides of the arc grooves by the elastic force of the compression springs 38, so that the two connecting square rods 33, the two limit frames 34 and the two micro-transformer shells 57 can be positioned, so that the two micro-transformer shells 57 can be closely fitted together to avoid the two micro-transformer shells 57 from separating during welding; (3) After the two micro-transformer shells 57 are fitted together, the two connecting rods 32, the two connecting square rods 33, the two limiting frames 34 and the two micro-transformer shells 57 can be rotated by rotating the two supporting shafts 28. The two micro-transformer shells 57 can be adjusted to an inclined state with the inner part facing upward to ensure the welding effect of the two micro-transformer shells 57 in the subsequent sequence. When the two supporting shafts 28 rotate, the two connecting springs 58 are in a compressed state, and the two arc-shaped card blocks 59 are separated from the corresponding arc-shaped card slots, so that the two supporting shafts 28 are limited to avoid interference when the two supporting shafts 28 rotate. When the transformer shell 57 is adjusted to a desired angle, the two arc-shaped blocks 59 can be pushed into the corresponding arc-shaped slots respectively by the elastic force of the two connecting springs 58, so that the two supporting shafts 28, the two connecting rods 32, the two limiting frames 34 and the two micro-transformer shells 57 can be positioned, and the two micro-transformer shells 57 can be kept at the current angle to prevent the angle of the two micro-transformer shells 57 from shifting during transmission. The arc-shaped blocks 59 are separated from the arc-shaped slots by rotation of external force, so that the two micro-transformer shells 57 can be rotated to achieve the subsequent rotation welding of the two micro-transformer shells 57. (4) After the two micro-transformer shells 57 are fixed and the angles are adjusted, the support plate 27 with the two micro-transformer shells 57 can be placed on the conveying platform 13, and the servo motor 3 can sequentially drive the driving wheel 4, the conveyor belt 5, the driven wheel 6, the two first gears 7, the two second gears 8, the two third gears 9 and the two fourth gears 10 to rotate, because the two first brackets 11 are connected to the two first gears 7 through the connecting pins, the two second brackets 12 are connected to the two fourth gears 10 through the fixing pins, the two first brackets 11 are connected to the two first gears 7 through the two limiting holes and the two limiting pins, and the two second brackets 12 are connected to the two fourth gears 10 through the two fixing holes and the two movable The two second gears 8, the two third gears 9 and the two fourth gears 10 are connected by pins, so when the two second gears 8, the two third gears 9 and the two fourth gears 10 rotate, they will drive the two first brackets 11, the two second brackets 12 and the conveying platform 13 to move up and down and forward and backward. When the conveying platform 13 moves downward, the support plate 27 will be placed on the welding frame 1. When the conveying platform 13 moves upward, the support plate 27 will be supported. When the conveying platform 13 moves forward, the support plate 27 will be pushed forward by one grid. When the conveying platform 13 moves backward, it can be restored to its original position. The support plate 27 with two micro-transformer shells 57 can be placed on the conveying platform 13 again. Then, through this method, the conveying platform 13 can simultaneously convey multiple support plates 27 with two micro-transformer shells 57; (5) When the support plate 27 with two micro-transformer shells 57 is transferred to the bottom of the welder 48, the four fixed racks 40 will respectively mesh with the four limit gears 43 through the gravity of the support plate 27 falling, and then respectively drive the four limit gears 43 and the four limit clamps 42 to rotate at an angle. When the four limit clamps 42 rotate, they will fit with the support plate 27, so that the support plate 27 can be clamped and fixed, avoiding the deviation of the support plate 27 when the two micro-transformer shells 57 are welded, so as to ensure the welding and fixing effect of the two micro-transformer shells 57. At the same time, the two transmission gears 29 will respectively mesh with the two movable gears 18, and the two first bevel gears 20 will respectively mesh with the two second bevel gears 23; (6) After the support plate 27 is fixed, the electric push rod 44 can sequentially drive the fixing box 45, the annular spring 46, the buffer rod 47 and the welder 48 to move downward, and the welder 48 can be moved to the starting position where the two micro-transformer shells 57 are fitted together, and then the two micro-transformer shells 57 can be welded by the welder 48. At the same time, when the welder 48 is fitted with the two micro-transformer shells 57, the annular spring 46 is in a compressed state, and the spring of the annular spring 46 can make the welder 48 have a buffering effect, so that when the two micro-transformer shells 57 are swinging and translating, the elastic force of the annular spring 46 can make the welder 48 always fit with the two micro-transformer shells 57, and there is no need to use the electric push rod 44 to always adjust the fit between the welder 48 and the two micro-transformer shells 57, so as to ensure the welding accuracy of the two micro-transformer shells 57; (7) The motor 14 can sequentially drive the two driving wheels 15, the two first conveyor belts 16, the two double pulleys 17, the two second conveyor belts 62, the two follower wheels 61, the two movable gears 18 and the two connecting gears 19 to rotate clockwise. Through the connection and cooperation between the second inner ratchet 64, the two first clamping blocks 22, the two first springs 21 and the movable pin, when the movable gear 18 rotates clockwise, the two first bevel gears 20 will not rotate, and only the two first clamping blocks 22 will slide on the inner side of the second inner ratchet 64. Because the two transmission gears 29 are respectively meshed with the two movable gears 18, when the two connecting gears 19 rotate clockwise, they will respectively drive the two transmission gears 29, The two support shafts 28, the two connecting rods 32, the two connecting square rods 33, the two limit frames 34 and the two micro-transformer shells 57 rotate counterclockwise. When the two micro-transformer shells 57 rotate counterclockwise, the welder 48 can perform swing welding on the joints of the two micro-transformer shells 57, and can weld the joints of the inner sides of the two micro-transformer shells 57. When the two micro-transformer shells 57 are adjusted to a flat state, the motor 14 can sequentially drive the two driving wheels 15, the two first conveyor belts 16, the two double pulleys 17, the two second conveyor belts 62, the two follower wheels 61, the two movable gears 18, the two connecting gears 19, the two second inner ratchet wheels 64 and the two first bevel gears 20 to rotate counterclockwise. The two second bevel gears 23 are meshed with the two second bevel gears 23 respectively. Therefore, when the two first bevel gears 20 rotate counterclockwise, the two second bevel gears 23 and the two bidirectional screws 24 are respectively driven to rotate clockwise. Because the two bidirectional screws 24 are respectively threadedly connected with the two threaded blocks 25, the two bidirectional screws 24 are respectively threadedly connected with the two threaded blocks 25. When the screw rod 24 rotates clockwise, it will drive the two threaded blocks 25, the U-shaped frame 26, the two support shafts 28, the two transmission gears 29, the two connecting rods 32, the two connecting square rods 33, the two limit frames 34 and the two micro transformer shells 57 to move forward in sequence. When the two micro transformer shells 57 move forward in translation, the joints of the inner planes of the two micro transformer shells 57 can be welded by the welder 48. At the same time, the two transmission gears 29 will be meshed with the two connecting gears 19 respectively. At this time, the two connecting gears 19 can respectively drive the two transmission gears 29 to rotate counterclockwise, thereby driving the two micro transformer shells 57 to rotate counterclockwise. Then, the swing and translation of the two micro transformer shells 57 can be controlled by this method.The sides, planes and sides of the two micro-transformer shells 57 can be completely welded in sequence, and the welding effect of the internal joints of the two micro-transformer shells 57 can be ensured. After the internal welding of the two micro-transformer shells 57 is completed, the two micro-transformer shells 57 are swung continuously, and the two micro-transformer shells 57 can be turned over, so that the outer sides of the two micro-transformer shells 57 face upward, and then the swing and translation adjustment of the two micro-transformer shells 57 are continued. The sides, planes and sides of the outer sides of the two micro-transformer shells 57 can be completely welded in sequence through the welder 48, and the welding effect of the external joints of the two micro-transformer shells 57 can be ensured. By this method, the two micro-transformer shells 57 can be welded on both sides, and the two micro-transformer shells 57 can be welded together. The stability of the welding of the two micro-transformer shells 57 can be ensured, so as to ensure the quality of the welding of the two micro-transformer shells 57; (8) When the welder 48 is welding the inner sides of the two micro-transformer shells 57, the first pump 50 will spray the black insulating paint on the inner side of the first dye box 49 onto the inner sides of the two micro-transformer shells 57 through the first hose 51, so that the inner sides of the two micro-transformer shells 57 have an insulating effect, thereby avoiding the phenomenon of electric shock caused by the components on the inner side of the micro-transformer when the micro-transformer is used later, so as to ensure the safety of the use of the micro-transformer. When the welder 48 is welding the outer sides of the two micro-transformer shells 57, the second pump 53 will spray the red anti-corrosion paint on the inner side of the second dye box 52 onto the outer sides of the two micro-transformer shells 57 through the second hose 54, so that the outer sides of the two micro-transformer shells 57 have an anti-corrosion effect, thereby increasing the service life of the micro-transformer. At the same time, applying red anti-corrosion paint on the outer sides of the micro-transformer shells 57 can serve as a warning, so that the micro-transformer can serve as a reminder when it is in use. (9) After the welding of the two micro-transformer shells 57 is completed, the conveying platform 13 is used to convey the plurality of support plates 27 equipped with the two micro-transformer shells 57. First, the two micro-transformer shells 57 that have been welded and painted can be continuously conveyed to facilitate the unloading of the two processed micro-transformer shells 57. When the conveying platform 13 drives the support plate 27 to move upward, the four fixed racks 40 move upward to separate the four limit clamps 42 from the support plate 27. The four fixed racks 40 are separated from the four limit gears 43 respectively. The four limit clamps 42 can be kept at the original angle by the elastic force of the four telescopic springs 41, so as to clamp and fix the next support plate 27 equipped with the two micro-transformer shells 57, and then the two spliced ​​micro-transformer shells 57 can be welded in sequence. (10) After the two micro-transformer shells 57 are welded, the two welded micro-transformer shells 57 are disassembled first, and then the color of the weld between the two micro-transformer shells 57 can be observed to determine whether the weld between the two micro-transformer shells 57 is qualified. When the color of the outer weld between the two micro-transformer shells 57 is black or dark red or the color of the inner weld between the two micro-transformer shells 57 is dark red or dark dark, it means that there is a weld at the weld between the two micro-transformer shells 57, indicating that the welding quality of the two micro-transformer shells 57 is unqualified. If the outer weld between the two micro-transformer shells 57 is all red and the inner weld between the two micro-transformer shells 57 is all black, it means that there is no weld at the weld between the two micro-transformer shells 57, indicating that the welding quality of the two micro-transformer shells 57 is qualified, and the welding effect of the two micro-transformer shells 57 can be detected.

[0038] Compared with the prior art, the overall structure is simple and easy to use. The welding device can be controlled to weld the inner curved surface and inner inclined surface of the irregularly shaped micro transformer shell 57. The staff does not need to turn over and adjust the micro transformer shell 57 to achieve the purpose of welding the irregularly shaped micro transformer shell 57 on multiple sides by the welding device, which saves time and effort, reduces the labor intensity of the staff, improves the range and effect of welding the micro transformer shell 57 by the welding equipment, realizes double-sided welding of the micro transformer shell 57, ensures the firmness of the welding, meets the actual welding requirements of the micro transformer, can be painted and tested, and can be put into large quantities. After the welding of the micro-transformer shell 57 is completed, the staff does not need to use a detector to detect the welds of all the welding places of the micro-transformer shell 57. It is only necessary to observe the color of the inner and outer welding places of the micro-transformer shell 57 to detect the welding quality of the micro-transformer shell 57. The detection method is very fast and convenient, which reduces the labor intensity of the staff. It is not necessary to use a welding robot to weld a large number of micro-transformer shells 57, which can save the welding cost of the micro-transformer shell 57. The purpose of welding the inner and outer curved surfaces, inclined surfaces and flat surfaces of the micro-transformer shell 57 can be achieved by using an ordinary welder 48, which can ensure the speed and accuracy of welding a large number of micro-transformer shells 57.

[0039] Embodiment 2: The present application also discloses a welding process for producing a micro transformer, based on the welding equipment for producing a micro transformer of the first embodiment, comprising the following steps: S1. The clamping member can clamp and fix the two welded micro-transformer shells 57, the adjusting member can fit the two micro-transformer shells 57 tightly together, the limiting member can position the two micro-transformer shells 57, and after the two micro-transformer shells 57 are fixed and the angle is adjusted, the two micro-transformer shells 57 are placed on the conveying table 13; S2. The conveying assembly can drive the conveying platform 13 to move up and down and forward and backward, so that the conveying platform 13 can simultaneously convey multiple micro transformer shells 57, and can convey two micro transformer shells 57 to the bottom of the welder 48, and can also discharge the processed micro transformer shells 57, and can cyclically convey the micro transformer shells 57. When the two micro transformer shells 57 are conveyed to the bottom of the welder 48, the fixing member can limit the two micro transformer shells 57 to be welded; S3. The electric push rod 44 can sequentially drive the fixing box 45, the annular spring 46 and the welder 48 to move up and down. When the two micro-transformer shells 57 are swinging and translating, the elastic force of the annular spring 46 can make the welder 48 always fit with the two micro-transformer shells 57 to ensure the welding accuracy of the two micro-transformer shells 57; S4. The driving member can drive the two micro-transformer shells 57 to rotate counterclockwise, and the welder 48 can perform arc welding on the inner side joints of the two micro-transformer shells 57.

Through the swing and translation of the two micro-transformer shells 57, the inner side, plane and side of the two micro-transformer shells 57 can be welded in sequence.

When the welder 48 is welding the inner sides of the two micro-transformer shells 57, the spray paint part can spray black insulating paint on the inner sides of the two micro-transformer shells 57, so that the inner sides of the two micro-transformer shells 57 have an insulating effect. When the welder 48 is welding the outer sides of the two micro-transformer shells 57, the spray paint part can spray red anti-corrosion paint on the outer sides of the two micro-transformer shells 57, so that the outer sides of the two micro-transformer shells 57 have an anti-corrosion effect. Observe the color of the welding point of the two micro-transformer shells 57 to determine whether the welding point of the two micro-transformer shells 57 is qualified; S6. When the color of the outer welding parts of the two micro-transformer shells 57 tends to be dark red or the color of the inner welding parts of the two micro-transformer shells 57 tends to be dark dark, the welding quality of the two micro-transformer shells 57 is unqualified.
