It is through the cooperation of these components that electronic devices can work normally. In the production process of electronic components such as inductors, due to the existence of enameled wire, it is necessary to spot weld the enameled wire and the inductor pins so that current can flow into the enameled wire through the pins.

[0003] The prior art also proposes some solutions, such as welding the pins and enameled wires of the inductor by a spot welder. To this end, the user needs to wind the enameled wire of the inductor around the pins of the inductor, and then put the pins wrapped with the enameled wire between the two electrodes of the spot welder. The two electrodes then clamp the pins and the enameled wire, and current is passed through at the same time to weld the enameled wire and the pins together.

The movable seat 4 will push the lower electrode 5 up. During the rising process, the lower electrode 5 will insert the pin of the inductor into the depression on the top of the lower electrode 5, and then drive the pin and the inductor body to rise until the pin contacts 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 loop, so that the current passes through the pin, and then heats the pin and the enameled wire, so that the pin and the enameled wire are welded together. Then the cylinder drives the movable seat 4 and the lower electrode 5 to reset. At this time, the conveyor belt 2 has sent the next empty fixed component to between the two columns 3, so the inductor that has just been welded It will be inserted into the empty fixed component and transported away by the conveyor belt 2, and then the conveyor belt 2 will move another fixed component with the inductor to be welded between the two columns 3, and then the previous processing steps can be repeated to complete the batch welding of the inductors.

[0034] like Figures 4 to 5 As shown, the end of the spring 10 close to the upper electrode 7 is fixedly connected with a connecting ring 11; the connecting ring 11 is fixedly connected to the upper electrode 7; the top surface of the fixed seat 6 is rotatably connected with a pair of symmetrically arranged adjusting rods 12; the two adjusting rods 12 extend to the inside of the sleeve rod 8, and the two adjusting rods 12 are threadedly connected to the connecting ring 11; an observation window 13 is provided on the surface of the sleeve rod 8; during operation, when the user simultaneously screws the two adjusting rods 12, the connecting ring 11 threadedly connected with the two adjusting rods 12 will drive the spring 10 to rise or fall, and observe the compression degree of the spring 10 from the observation window 13, thereby changing the pressure between the upper electrode 7 and the lower electrode 5, and then facilitating the user to select the appropriate pressure according to different welding materials and thicknesses to ensure the final welding quality.

[0035] like Figures 4 to 5 As shown, the top surfaces of the two adjusting rods 12 are fixedly connected with gears 14; the two gears 14 are meshed and connected with an inner ring gear 15; the inner ring gear 15 is rotatably connected to the top surface of the fixed seat 6; during operation, when the user needs to synchronously screw the two adjusting rods 12, the user can screw the inner ring gear 15, and the inner ring gear 15 drives the two gears 14 to rotate synchronously, and then the two synchronously rotating gears 14 respectively drive the two adjusting rods 12 to rotate synchronously, thereby achieving that the user only needs to rotate one inner ring gear 15 to complete the adjustment of the spring 10, thereby reducing the user's operating difficulty and improving the usability of the embodiment of the present invention.

[0036] like Figures 4 to 5As shown, a tooth plate 16 is fixedly connected to the top surface of the movable seat 4; a gear 2 17 is rotatably connected to the surface of the sleeve rod 8 at a position corresponding to the tooth plate 16; a crown gear 18 is meshedly connected to the bottom of the gear 2 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 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 and the gear 2 17 will separate, 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.

[0037] like Figure 1 and Figure 6 As shown, the fixing assembly includes a connecting seat 19; the connecting seat 19 is evenly fixed on the belt surface of the conveyor belt 2; a bottom plate 20 is installed on the 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 the 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 evenly arranged spring 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 clearance groove 25 is provided on the surface of the fixing rod top plate at the inclined part 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 pin of the inductor face the output The conveying direction of the conveyor belt 2, and then when the conveyor belt 2 drives the connecting seat 19 and the bottom plate 20, baffle 22, clamping plate 23, spring piece 24 and fixed plate 21 thereon to move between the two pillars 3, the lower electrode 5 will drive the inductor to rise through the pins. Since in this process, the conveyor belt 2 has been moving with the bottom plate 20, baffle 22, clamping plate 23, spring piece 24 and fixed plate 21, when the lower electrode 5 drives the inductor to leave between the clamping plate 23 and the baffle 22, the inductor will squeeze the clamping plate 23, so that the clamping plate 23 moves toward the give way groove 25 and compresses the spring piece 24, so that the inductor can finally be driven by the lower electrode 5 to smoothly get out of between the clamping plate 23 and the baffle 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 clamping plate 23 and the baffle 22, the inclined setting of the top of the clamping plate 23 can also further facilitate the insertion of the inductor.

[0038] like Figure 6 As shown, a slide groove 26 is provided on one side of the bottom plate 20 close to the baffle 22; the baffle 22 is slidably connected to the slide groove 26; a threaded rod 27 is rotatably connected in the slide groove 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 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 embodiments of the present invention.

[0039] like 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; the top surface of the base 1 is slidably connected to a support plate 28 on one side of the conveyor belt 2, and the support plate 28 is adjusted by a screw; the top surface of the support plate 28 is fixedly connected to a toothed plate 29; the end of the threaded rod 27 away from the fixed plate 21 is fixedly connected to a gear 30; the top surface of the support plate 28 and the side away from the conveyor belt 2 is fixedly connected to a limiting plate 31; the limiting plate 31 is L-shaped; the bottom surface of the horizontal part of the limiting plate 31 is fixedly connected to a pressing plate 32, and the bottom surface of the pressing plate 32 is arc-shaped and smooth; 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 by rotating the rotating assembly 20 rotates, and makes the threaded rod 27 at the slide groove 26 and the gear three 30 at the end face the support plate 28. Then the user moves the support plate 28 so that the gear three 30 can mesh with the tooth plate two 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 through the support plate 28, the gear three 30 meshes with the tooth plate two 29, thereby driving the gear three 30 to rotate, and then the gear three 30 drives the threaded rod 27 to rotate, thereby realizing batch adjustment of the distance between the baffle 22 and the clamping plate 23. At the same time, when the gear three 30 passes through the tooth plate two 29, the pressure plate 32 on the surface of the limit plate 31 will squeeze the threaded rod 27 close to the end of the gear three 30, thereby ensuring that the gear three 30 and the tooth plate two 29 can mesh normally and avoiding the gear three 30 from bouncing.

[0040] like Figure 6 to Figure 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 Fig. 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 on the fixed components on the surface of the conveyor belt 2, and then the conveyor belt 2 will transport the fixed components with the inductors to be welded to between the pairs of columns 3, and then the cylinder will push the moving seat 4 to rise, and the moving seat 4 will push the lower electrode 5 to rise. During the rising process, the lower electrode 5 will insert the pin of the inductor into the depression on the top of the lower electrode 5, and then drive the pin and the inductor body to rise until the pin contacts 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 loop, so that the current passes through the pin, and then heats the pin and the enameled wire, so that the pin and the enameled wire are welded together, and then the cylinder drives the moving seat 4 to And the lower electrode 5 is reset, at this time, the conveyor belt 2 has sent the next empty fixed component to between the two pillars 3, so the inductor that has just been welded will be inserted into the empty fixed component and transported away by the conveyor belt 2, and then the conveyor belt 2 will move another fixed component with the inductor to be welded between the two pillars 3, and then the previous processing steps can be repeated continuously to complete the batch welding of the inductors. The cooperation of the two upper electrodes 7 and the lower electrode 5 realizes the synchronous welding of the two pins of the inductor, thereby saving the time of flipping the inductor. At the same time, the inductor interval is placed in the fixed component, which can also enable the conveyor belt 2 to work continuously without multiple shutdowns to wait for the inductor welding to be completed, thereby further improving the working efficiency of the embodiment of the present invention.

[0043] In the process of the lower electrode 5 driving the inductor pin to rise, the upper electrode 7 will first drive the pin to squeeze the upper electrode 7, and drive the upper electrode 7 to rise together. At this time, the upper electrode 7 will squeeze 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 circuit, so that the current can pass through the pin smoothly, and then the pin and the enameled wire are welded together. The pressure between the upper electrode 7 and the lower electrode 5 is guaranteed by the compression of the spring 10, and the inductor can also be kept away from the fixed component to avoid the collision between the continuously moving fixed component and the inductor being welded.

[0044] When the user simultaneously screws the two adjusting rods 12, the connecting ring 11 threadedly connected to the two adjusting rods 12 will drive the spring 10 to rise or fall, and the compression degree of the spring 10 can be observed from the observation window 13, thereby changing the pressure between the upper electrode 7 and the lower electrode 5, thereby facilitating the user to select the 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] In order to facilitate the user to adjust the spacing between the baffle plate 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 slide groove 26 and the gear three 30 at the end face the support plate 28. Then the user moves the support plate 28 so that the gear three 30 can mesh with the tooth plate two 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 through the support plate 28, the gear three 30 meshes with the tooth plate two 29, thereby driving the gear three 30 to rotate, and then the gear three 30 drives the threaded rod 27 to rotate, thereby realizing batch adjustment of the spacing between the baffle plate 22 and the clamping plate 23. At the same time, when the gear three 30 passes through the tooth plate two 29, the pressure plate 32 on the surface of the limit plate 31 will squeeze the threaded rod 27 close to the end of the gear three 30, thereby ensuring that the gear three 30 and the tooth plate two 29 can mesh normally and avoid the gear three 30 from bouncing.

[0050] When the user needs to rotate the base plate 20, the user needs to pull the base plate 20 to move it away from the connecting seat 19, thereby driving the upper sleeve 33 to move away from the lower sleeve 34, so that the protrusion 35 on the bottom surface of the upper sleeve 33 can be disengaged from the groove 36 on the surface of the lower sleeve 34, and at the same time, the spring 2 37 will be stretched. At this time, the user rotates it another 90 degrees, and then releases the base plate 20. The stretched spring 2 37 is restored, thereby driving the upper sleeve 33 to be buckled 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 base plate 20 and the connecting seat 19, so that when the conveyor belt 2 transports the connecting seat 19 and the base plate 20, the connecting seat 19 and the base plate 20 will not rotate at will.

[0051] When the clamping plate 23 and the baffle plate 22 transport the welded inductor to the guide groove 40, the servo motor will drive the rotating roller 38 to rotate, and the rotating roller 38 will drive the elastic plate 39 to rotate, thereby continuously moving 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.
