Description

Technical Field

[0002] Electronic components are the basic units that make up electronic devices. There is a wide variety of them, such as passive components like resistors, capacitors, inductors, and active components like diodes, triodes, and integrated circuits. It is through the cooperation of these components that electronic devices can work properly. During the production process of electronic components such as inductors, due to the presence of enameled wires, spot welding of the enameled wires and inductor pins is required so that current can flow through the pins into the enameled wires.

[0003] Some solutions have also been proposed in the prior art. For example, a spot welder is used to weld the pins of an inductor and the enameled wire. For this purpose, the user needs to wind the enameled wire of the inductor around the pins of the inductor, and then place the pins with the wound enameled wire between the two electrodes of the spot welder. Subsequently, the two electrodes clamp the pins and the enameled wire, and at the same time, current is passed through to weld the enameled wire and the pins together.

[0004] In the prior art during the spot welding process of inductors, an inductor often has two pairs of pins. Therefore, after the user welds the pins of the inductor, the position of the inductor needs to be adjusted, and then the other pin of the inductor is welded, which reduces the processing efficiency and is not conducive to the batch welding of inductors.

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] Such as Figures 1 to 3As shown in the figure, a spot welding device for an inductor and an enameled wire according to an embodiment of the present invention includes a base 1; a conveyor belt 2 is installed on the top surface of the base 1; both sides of the conveyor belt 2 are fixedly connected with columns 3, and the two columns 3 are symmetrically arranged; on the side surfaces of the two columns 3 close to each other at the bottom position, there are sliding connections with moving seats 4, and the moving seats 4 are driven by cylinders; a lower electrode 5 is fixedly connected to the top surface of the moving seat 4, and the top surface of the lower electrode 5 is concave; on the side surfaces of the two columns 3 close to each other at the top position, there are fixedly connected with fixed seats 6; a connecting component is installed on the bottom surface of the fixed seat 6; an upper electrode 7 is installed at the bottom of the connecting component; the connecting component is used to connect the upper electrode 7 and the fixed seat 6; the upper electrode 7 and the connecting component are respectively connected to the positive and negative electrodes of an external power supply; a plurality of uniformly arranged fixing components are installed on the belt surface of the conveyor belt 2; the fixing components are used to fix electronic components; during operation, when batch welding of inductors is required, the user needs to place the inductors to be welded at intervals at the fixing components on the surface of the conveyor belt 2, and then the conveyor belt 2 transports the fixing components loaded with the inductors to be welded between the paired columns 3. Subsequently, the cylinder pushes the moving seat 4 to rise, and the moving seat 4 will push the lower electrode 5 to rise. During the rising process of the lower electrode 5, the pins of the inductor will be inserted into the depression at the top of the lower electrode 5, and then the pins and the inductor body will be driven to rise until the pins contact the upper electrode 7 at the fixed seat 6. At this time, the external power supply connects the upper electrode 7 and the lower electrode 5 to form a circuit, so that current passes through the pins, thereby heating the pins and the enameled wire, so that the pins and the enameled wire are welded together. Subsequently, the cylinder drives the moving seat 4 and the lower electrode 5 to reset. At this time, the conveyor belt 2 has sent the next empty fixing component between the two columns 3. Therefore, the just-welded inductor will be inserted into the empty fixing component and transported away by the conveyor belt 2. Then the conveyor belt 2 will move another fixing component loaded with the inductor to be welded between the two columns 3. After that, the previous processing steps can be continuously repeated to complete the batch welding of the inductors. Through the cooperation of the two upper electrodes 7 and the lower electrode 5, synchronous welding of the two pins of the inductor is achieved, thereby saving the time for flipping the inductor. At the same time, the inductors are placed in the fixing components at intervals, which can also enable the conveyor belt 2 to continuously work without having to stop several times to wait for the inductors to be welded, thereby further improving the working efficiency of the embodiment of the present invention.

[0033] As Figures 3 to 5As shown in the figure, the connection component includes a sleeve rod 8; the top surface of the sleeve rod 8 is fixedly connected to the fixed seat 6, and the upper electrode 7 is located inside the sleeve rod 8; a conductive column 9 is fixedly connected to the bottom surface of the fixed seat 6 inside the sleeve rod 8, and the conductive column 9 is connected to an external power supply; a first spring 10 is installed between the upper electrode 7 and the fixed seat 6; the first spring 10 is sleeved outside the conductive column 9, and the first spring 10 is located inside the sleeve rod 8; during operation, when the lower electrode 5 drives the inductor pin to rise, the upper electrode 7 will first drive the pin to press against the upper electrode 7 and drive the upper electrode 7 to rise together. At this time, the upper electrode 7 will compress the spring until the top of the upper electrode 7 touches the conductive column 9. At this time, the conductive column 9, the upper electrode 7, the lower electrode 5 and the external power supply form a complete circuit, enabling current to pass smoothly through the pin, and then enabling the pin to be welded to the enameled wire. By compressing the first spring 10, the pressure between the upper electrode 7 and the lower electrode 5 is ensured, and at the same time, the inductor can be kept away from the fixing component to avoid the constantly moving fixing component colliding with the inductor being welded.

[0034] As Figures 4 to 5 shown in the figure, a connection ring 11 is fixedly connected to one end of the first spring 10 close to the upper electrode 7; the connection ring 11 is fixedly connected to the upper electrode 7; a pair of symmetrically arranged adjusting rods 12 are rotatably connected to the top surface of the fixed seat 6; both of the two adjusting rods 12 extend into the sleeve rod 8, and both of the two adjusting rods 12 are threadedly connected to the connection ring 11; an observation window 13 is provided on the surface of the sleeve rod 8; during operation, when the user synchronously rotates the two adjusting rods 12, the connection ring 11 commonly threadedly connected to the two adjusting rods 12 will drive the first spring 10 to rise or fall, and the compression degree of the first spring 10 can be observed from the observation window 13, thereby changing the pressure between the upper electrode 7 and the lower electrode 5, and further facilitating the user to select an appropriate pressure according to different welding materials and thicknesses to ensure the final welding quality.

[0035] As Figures 4 to 5 shown in the figure, a first gear 14 is fixedly connected to the top surface of both of the two adjusting rods 12; the two first gears 14 are commonly meshed with an internal gear ring 15; the internal gear ring 15 is rotatably connected to the top surface of the fixed seat 6; during operation, when the user needs to synchronously rotate the two adjusting rods 12, the user can rotate the internal gear ring 15. The internal gear ring 15 drives the two first gears 14 to rotate synchronously, and then the two synchronously rotating first gears 14 respectively drive the two adjusting rods 12 to rotate synchronously. Thus, it is realized that the user can complete the adjustment of the first spring 10 by only rotating one internal gear ring 15, thereby reducing the operation difficulty of the user and improving the usability of the embodiment of the present invention.

[0036] As Figures 4 to 5As shown in the figure, a first toothed plate 16 is fixedly connected to the top surface of the movable seat 4; a second gear 17 is rotatably connected to the surface of the sleeve rod 8 at a position corresponding to the first toothed plate 16; a crown gear 18 is meshed and connected to the bottom of the second gear 17; the crown gear 18 is rotatably connected to the bottom of the sleeve rod 8, and the crown gear 18 is slidably connected to the upper electrode 7; during operation, when the movable seat 4 rises, the movable seat 4 will also drive the first toothed plate 16 to rise, the rising first toothed plate 16 will drive the second gear 17 to rotate, and the second gear 17 will drive the crown gear 18 and the upper electrode 7 to rotate. Subsequently, the first toothed plate 16 is disengaged from the second gear 17, and the upper electrode 7 and the lower electrode 5 normally complete the welding between the lead and the enameled wire. Then, when the movable seat 4 is reset, the first toothed plate 16 will drive the crown gear 18 and the upper electrode 7 to rotate through the second gear 17. Thus, when the upper electrode 7 is separated from the lead, it can rotate itself to push the lead, thereby preventing the lead from sticking to the surface of the upper electrode 7 or the lower electrode 5 due to welding.

[0037] As Figure 1 and Figure 6 shown in the figure, the fixing assembly includes a connecting seat 19; the connecting seats 19 are uniformly and fixedly connected to the belt surface of the conveyor belt 2; a bottom plate 20 is installed on one side of the connecting seat 19 away from the belt surface of the conveyor belt 2; a fixing plate 21 and a baffle 22 are arranged on one side of the bottom plate 20 away from the connecting seat 19; the fixing plate 21 is fixedly connected to the bottom plate 20 and is located at the end of the bottom plate 20; the fixing plate 21 and the baffle 22 are respectively located upstream and downstream of the conveying direction of the conveyor belt 2; a clamping plate 23 is slidably connected to the surface of the fixing plate 21; a plurality of uniformly arranged elastic pieces 24 are fixedly connected between the clamping plate 23 and the mounting plate, and the top of the clamping plate 23 is inclined; a relief groove 25 is formed in the surface of the top plate of the fixing rod at the inclined position of the clamping plate 23; during operation, when the user needs to fix the inductor on the conveyor belt 2, the user needs to insert the coil part of the inductor between the clamping plate 23 and the baffle 22 and make the lead of the inductor face the conveying direction of the conveyor belt 2. Then, when the conveyor belt 2 drives the connecting seat 19 and the bottom plate 20, the baffle 22, the clamping plate 23, the elastic pieces 24 and the fixing plate 21 thereon to move between the two columns 3, the lower electrode 5 will drive the inductor to rise through the lead. Since the conveyor belt 2 has been driving the bottom plate 20, the baffle 22, the clamping plate 23, the elastic pieces 24 and the fixing plate 21 to move during this process, when the lower electrode 5 drives the inductor to disengage from between the clamping plate 23 and the baffle 22, the inductor will squeeze the clamping plate 23, causing the clamping plate 23 to move towards the relief groove 25 and compress the elastic pieces 24. As a result, the inductor can finally be smoothly disengaged from between the clamping plate 23 and the baffle 22 under the drive of the lower electrode 5, and the conveyor belt 2 can operate normally. When the inductor is driven by the upper electrode 7 and the lower electrode 5 to be inserted back between the clamping plate 23 and the baffle 22 again, the inclined setting of the top of the clamping plate 23 can further facilitate the insertion of the inductor.

[0038] AsFigure 6 As shown, a chute 26 is provided on one side of the bottom plate 20 close to the baffle 22; the baffle 22 is slidably connected to the chute 26; a threaded rod 27 is rotatably connected in the chute 26, and the threaded rod 27 is threadedly connected to the baffle 22; during operation, when the user needs to adapt to inductors of different thicknesses, the user can turn the threaded rod 27, and the threaded rod 27 drives the baffle 22 to slide in the chute 26, so as to adjust the distance between the baffle 22 and the clamping plate 23, and then adapt to inductors of different thicknesses, thereby improving the applicable range of the embodiment of the present invention.

[0039] As Figure 1 、 Figure 6 and Figure 8 As shown, a rotating assembly is installed between the bottom plate 20 and the connecting seat 19; the rotating assembly enables the bottom plate 20 to rotate on the surface of the connecting seat 19; a support plate 28 is slidably connected to one side of the conveyor belt 2 on the top surface of the base 1, and the support plate 28 is adjusted by a screw; a second toothed plate 29 is fixedly connected to the top surface of the support plate 28; a third gear 30 is fixedly connected to the end of the threaded rod 27 away from the fixed plate 21; a limiting plate 31 is fixedly connected to the top surface of the support plate 28 and away from the conveyor belt 2; the limiting plate 31 is arranged in an L shape; a pressing plate 32 is fixedly connected to the bottom surface of the horizontal part of the limiting plate 31, and the bottom surface of the pressing plate 32 is smoothly curved; during operation, in order to facilitate the user to adjust the distance between the baffle 22 and the clamping plate 23, the user can drive the bottom plate 20 to rotate by rotating the rotating assembly, and make the threaded rod 27 at the chute 26 and the third gear 30 at the end face the support plate 28. Then the user moves the support plate 28 so that the third gear 30 can mesh with the second toothed plate 29 on the top surface of the support plate 28. Then the user starts the conveyor belt 2. When the conveyor belt 2 drives the bottom plate 20 to pass by the support plate 28, the third gear 30 meshes with the second toothed plate 29, thereby driving the third gear 30 to rotate, and then the third gear 30 drives the threaded rod 27 to rotate, so as to realize the batch adjustment of the distance between the baffle 22 and the clamping plate 23. At the same time, when the third gear 30 passes by the second toothed plate 29, the pressing plate 32 on the surface of the limiting plate 31 will squeeze one end of the threaded rod 27 close to the third gear 30, thereby ensuring that the third gear 30 can mesh with the second toothed plate 29 normally and preventing the third gear 30 from bouncing.

[0040] As Figures 6 to 7As shown, the rotating assembly includes an upper sleeve 33 and a lower sleeve 34; the upper sleeve 33 is fixedly connected to the bottom surface of the bottom plate 20; the lower sleeve 34 is fixedly connected to the top surface of the connecting seat 19; the bottom surface of the upper sleeve 33 is fixedly connected with four uniform protrusions 35; the top surface of the lower sleeve 34 is provided with four uniformly arranged grooves 36, and the protrusions 35 are adapted to the grooves 36; a spring 2 37 is rotatably connected between the bottom plate 20 and the connecting seat 19, and the spring 2 37 is located inside the upper sleeve 33 and the lower sleeve 34; during operation, when the user needs to rotate the bottom plate 20, the user needs to pull the bottom plate 20 away from the connecting seat 19, thereby driving the upper sleeve 3 3 also moves away from the lower sleeve 34, so that the protrusion 35 on the bottom surface of the upper sleeve 33 can be separated from the groove 36 on the surface of the lower sleeve 34, and the spring 2 37 is stretched at the same time. At this time, the user rotates it 90 degrees again, and then releases the bottom plate 20, and the stretched spring 2 37 is restored, thereby driving the upper sleeve 33 to buckle back to the surface of the lower sleeve 34, and the protrusion 35 on the bottom surface of the upper sleeve 33 can also be inserted into the groove 36 on the surface of the lower sleeve 34, thereby completing the locking between the upper sleeve 33 and the lower sleeve 34, and then realizing the locking between the bottom plate 20 and the connecting seat 19, so that when the conveyor belt 2 transports the connecting seat 19 and the bottom plate 20, the connecting seat 19 and the bottom plate 20 will not rotate at will.

[0041] like Figure 1 and Figure 9 As shown, the top surface of the base 1 is rotatably connected to a pair of rotating rollers 38 at the downstream of the conveyor belt 2, and the rotating rollers 38 are driven by a servo motor; the surface of the driving roller is rotatably connected to a plurality of evenly arranged elastic plates 39; a guide groove 40 is provided on the top surface of the base 1 at the downstream of the conveyor belt 2; during operation, when the clamping plate 23 and the baffle plate 22 transport the welded inductor to the guide groove 40, the servo motor at this time will drive the rotating rollers 38 to rotate, and then the rotating rollers 38 will drive the elastic plates 39 to rotate, and then continuously move the welded inductor between the clamping plate 23 and the baffle plate 22, so that the welded inductor falls off and falls into the guide groove 40, and finally slides to the outside of the base 1, so that the user can collect it conveniently.

[0042] During operation, when batch welding of inductors is required, the user needs to place the inductors to be welded at intervals at the fixing components on the surface of the conveyor belt 2, and then the conveyor belt 2 transports the fixing components with the inductors to be welded between the paired columns 3. Subsequently, the cylinder pushes the moving seat 4 to rise, and the moving seat 4 in turn pushes the lower electrode 5 to rise. During the rising process of the lower electrode 5, the pins of the inductor are inserted into the depressions at the top of the lower electrode 5, and then the pins and the inductor body are driven to rise until the pins contact the upper electrode 7 at the fixing seat 6. At this time, the external power supply connects the upper electrode 7 and the lower electrode 5 to form a loop, enabling current to pass through the pins, thereby heating the pins and the enameled wire, so that the pins and the enameled wire are welded together. Subsequently, the cylinder drives the moving seat 4 and the lower electrode 5 to reset. At this time, the conveyor belt 2 has sent the next empty fixing component between the two columns 3. Therefore, the just-welded inductor will be inserted into the empty fixing component and transported away by the conveyor belt 2. Then, the conveyor belt 2 will move another fixing component with the inductor to be welded between the two columns 3. After that, the previous processing steps can be continuously repeated to complete the batch welding of the inductors. Through the cooperation of the two upper electrodes 7 and the lower electrode 5, synchronous welding of the two pins of the inductor is achieved, thereby saving the time for flipping the inductor. At the same time, the inductors are placed in the fixing components at intervals, which also enables the conveyor belt 2 to continuously operate without having to stop multiple times waiting for the inductors to be welded, thus further improving the working efficiency of the embodiments of the present invention.

[0043] During the process of the lower electrode 5 driving the inductor pins to rise, the upper electrode 7 will first drive the pins to press against the upper electrode 7 and drive the upper electrode 7 to rise together. At this time, the upper electrode 7 will compress the spring until the top of the upper electrode 7 contacts the conductive column 9. At this time, the conductive column 9, the upper electrode 7, the lower electrode 5, and the external power supply form a complete loop, enabling current to pass smoothly through the pins, thereby welding the pins and the enameled wire together. By compressing the spring 10, the pressure between the upper electrode 7 and the lower electrode 5 is ensured, and at the same time, the inductor is kept away from the fixing component to prevent the continuously moving fixing component from colliding with the inductor being welded.

[0044] When the user synchronously turns the two adjusting rods 12, the connecting ring 11 commonly threadedly connected to the two adjusting rods 12 will drive the spring 10 to rise or fall, and observe the compression degree of the spring 10 through the observation window 13, thereby changing the pressure between the upper electrode 7 and the lower electrode 5, and facilitating the user to select an appropriate pressure according to different welding materials and thicknesses to ensure the final welding quality.

[0045] When the user needs to rotate the two adjustment rods 12 synchronously, the user can rotate the inner gear ring 15, and the inner gear ring 15 drives the two gears 14 to rotate synchronously, and then the two synchronously rotating gears 14 respectively drive the two adjustment rods 12 to rotate synchronously, thereby achieving that the user only needs to rotate one inner gear ring 15 to complete the adjustment of the spring 10, thereby reducing the operating difficulty of the user and improving the usability of the embodiment of the present invention.

[0046] When the movable seat 4 rises, the movable seat 4 will also drive the tooth plate 16 to rise, and the rising tooth plate 16 will drive the gear 2 17 to rotate, and the gear 2 17 will drive the crown gear 18 and the upper electrode 7 to rotate, and then the tooth plate 16 will be separated from the gear 2 17, and the upper electrode 7 and the lower electrode 5 will normally complete the welding between the pin and the enameled wire, and then when the movable seat 4 is reset, the tooth plate 16 will drive the crown gear 18 and the upper electrode 7 to rotate through the gear 2 17, so that when the upper electrode 7 is separated from the pin, it can move the pin by rotating itself, thereby preventing the pin from sticking to the surface of the upper electrode 7 or the lower electrode 5 due to welding.

[0047] When the user needs to fix the inductor on the conveyor belt 2, the user needs to insert the coil part of the inductor between the clamping plate 23 and the baffle plate 22, and make the pin of the inductor face the conveying direction of the conveyor belt 2. Then, when the conveyor belt 2 drives the connecting seat 19 and the bottom plate 20, baffle plate 22, clamping plate 23, spring piece 24 and fixing plate 21 thereon to move between the two columns 3, the lower electrode 5 will drive the inductor to rise through the pin. During this process, the conveyor belt 2 is always carrying the bottom plate 20, baffle plate 22, clamping plate 23, spring piece 24 and fixing plate 21. The plate 21 moves, so when the lower electrode 5 drives the inductor to escape from between the clamp plate 23 and the baffle plate 22, the inductor will squeeze the clamp plate 23, causing the clamp plate 23 to move toward the clearance groove 25 and compress the spring 24, so that the inductor can finally be driven by the lower electrode 5 to smoothly escape from between the clamp plate 23 and the baffle plate 22, and the conveyor belt 2 can work normally. When the inductor is driven by the upper electrode 7 and the lower electrode 5 and is reinserted between the clamp plate 23 and the baffle plate 22, the inclined setting of the top of the clamp plate 23 can further facilitate the insertion of the inductor.

[0048] When the user needs to adapt to inductors of different thicknesses, the user can screw the threaded rod 27, and the threaded rod 27 drives the baffle 22 to slide in the slide groove 26, thereby adjusting the distance between the baffle 22 and the clamping plate 23, and then adapting to inductors of different thicknesses, thereby improving the scope of application of the embodiment of the present invention.

[0049] To facilitate the user to adjust the distance between the baffle 22 and the clamping plate 23, the user can drive the bottom plate 20 to rotate by rotating the rotating assembly, and make the threaded rod 27 at the chute 26 and the third gear 30 at the end face the support plate 28. Subsequently, the user moves the support plate 28 so that the third gear 30 can mesh with the second toothed plate 29 on the top surface of the support plate 28. Then the user turns on the conveyor belt 2. When the conveyor belt 2 drives the bottom plate 20 past the support plate 28, the third gear 30 meshes with the second toothed plate 29, thereby driving the third gear 30 to rotate. Then the third gear 30 drives the threaded rod 27 to rotate, so as to realize the batch adjustment of the distance between the baffle 22 and the clamping plate 23. At the same time, when the third gear 30 passes the second toothed plate 29, the pressing plate 32 on the surface of the limiting plate 31 will press one end of the threaded rod 27 close to the third gear 30, thereby ensuring that the third gear 30 can mesh with the second toothed plate 29 normally and preventing the third gear 30 from bouncing.

[0050] When the user needs to rotate the bottom plate 20, the user needs to pull the bottom plate 20 away from the connecting seat 19, thereby driving the upper sleeve 33 to also move away from the lower sleeve 34, so that the convex block 35 on the bottom surface of the upper sleeve 33 can disengage from the groove 36 on the surface of the lower sleeve 34. At the same time, the second spring 37 will also be stretched. At this time, the user rotates 90 degrees and then releases the bottom plate 20. The stretched second spring 37 returns, thereby driving the upper sleeve 33 to snap back onto the surface of the lower sleeve 34 again, and the convex block 35 on the bottom surface of the upper sleeve 33 can also be inserted into the groove 36 on the surface of the lower sleeve 34, thereby completing the locking between the upper sleeve 33 and the lower sleeve 34, and further realizing the locking between the bottom plate 20 and the connecting seat 19, so that when the conveyor belt 2 transports the connecting seat 19 and the bottom plate 20, the connecting seat 19 and the bottom plate 20 will not rotate randomly.

[0051] When the clamping plate 23 and the baffle 22 transport the welded inductor to the guiding groove 40, the servo motor at this time will drive the rotating roller 38 to rotate, and then the rotating roller 38 drives the elastic plate 39 to rotate, thereby continuously dialing the inductor welded between the clamping plate 23 and the baffle 22, so that the welded inductor falls off and drops into the guiding groove 40, and finally slides outside the base 1, thus facilitating the user to collect it.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
