Technical Field
[0001] This invention belongs to the field of magnetic core assembly technology, and specifically relates to a production line for assembling magnetic core components. Background Technology
[0002] The magnetic core assembly is a common component in solenoid valves. A magnetic core typically consists of a core body, a steel sheet, and a retaining ring. The steel sheet is mounted at one end of the core body via a cylindrical pin, and the retaining ring is mounted at the other end. Because the cylindrical pin needs to be pressed into the core body by a punch, the pressing force is difficult to control. Currently, magnetic cores are assembled manually, resulting in low overall assembly efficiency. The operator first places the steel sheet into the core body, then uses a stamping device to press the cylindrical pin into the core body, thus connecting the steel sheet; then, the retaining ring is pressed into a slot in the core body using the same stamping device. Due to the large number of magnetic cores required in production, manual assembly using stamping equipment is inefficient. Furthermore, the positioning of the cylindrical pin and retaining ring is poor during manual assembly, leading to easy damage after assembly and affecting product quality. Therefore, a production line for assembling magnetic core assemblies needs to be designed to overcome these difficulties. Summary of the Invention
[0003] This invention addresses the problems existing in the prior art by designing a production line for assembling magnetic core components. The invention uses a synchronous belt assembly to transport materials; a feeding robot assembly to feed materials; a pin pressing assembly to pre-press the cylindrical pins; a steel sheet feeding assembly to assemble the steel sheets and fully press the cylindrical pins in place; and a spring clamping assembly to position and press the springs. The overall assembly is efficient and the assembly process is safe and reliable.
[0004] The objective of this invention is achieved through the following technical solution: a production line for assembling iron core components, comprising a machine platform, a synchronous belt assembly on the machine platform, and sequentially arranged in the transport direction of the synchronous belt assembly: a feeding robot assembly, a pressing pin assembly, a steel sheet feeding assembly, and a pressing spring assembly; the synchronous belt assembly includes a mounting bracket and a transfer device that can move relative to the machine platform, and an iron core rotating assembly is located below the feeding robot assembly; the pressing pin assembly includes a pressing pin cylinder and a pressing pin head, and an isolation cylinder is provided on the pressing pin head; the steel sheet feeding assembly includes a first vibrator, a pushing cylinder, a positioning cylinder, a baffle cylinder, and a steel sheet guide rail, with a lifting cylinder located directly below the steel sheet guide rail, the positioning cylinder and the baffle cylinder located on the side of the steel sheet guide rail, and the pushing cylinder and the first vibrator located at the end of the steel sheet guide rail; the pressing spring assembly includes a first cylinder and a pressing spring block, and a plurality of evenly distributed magnets are provided on the pressing spring block.
[0005] Preferably, the loading robot assembly includes a first bracket with a first base plate fixedly connected thereto; a first slide rail horizontally arranged on the first base plate, and a first platform on the first slide rail; a second cylinder on the first bracket, with its piston shaft connected to the first platform; a second slide rail vertically arranged on the first platform, with its second platform on the second slide rail; a third cylinder on the first platform, with its piston shaft connected to the second platform; a first rotary cylinder at one end of the second platform and a first gripping cylinder at the other end; a second gripping cylinder fixedly connected to the rotating head of the first rotary cylinder; a synchronous belt assembly and a loading conveyor line on both sides of the first bracket, respectively, with the iron core rotating assembly positioned between the synchronous belt assembly and the loading conveyor line.
[0006] When the second cylinder operates, it pushes the first platform to move horizontally along the first slide rail. When the third cylinder operates, it pushes the second platform to move vertically along the second slide rail. The second platform is equipped with a first clamping cylinder and a second clamping cylinder, allowing the iron core body to be transported horizontally and vertically by the loading robot assembly. Since the orientation of the iron core body transported from the loading line is random, the first rotary cylinder drives the second clamping cylinder to rotate, thus facilitating the adjustment of the orientation of the iron core body so that the end of the iron core body with the slot faces the pressure spring assembly. Because the second platform has both a first clamping cylinder and a second clamping cylinder, two iron core bodies can be transported simultaneously, resulting in higher transport efficiency. The second clamping cylinder transports the iron core body from the loading line to the iron core rotating assembly, while the first clamping cylinder transports the iron core body from the iron core rotating assembly to the transfer device on the transfer synchronous belt assembly.
[0007] Preferably, the end of the feeding assembly line is provided with a first placement groove, and the end of the first placement groove is provided with a distance sensor; one end of the first slide rail is located near the first placement groove, and the other end is located near the initial end of the flow timing belt assembly; a fixing block is provided between the first clamping cylinder and the second platform to fix the two, and the first clamping cylinder and the second clamping cylinder are located at the same horizontal height.
[0008] The end of the iron core body with the slot has a through hole, allowing the distance sensor to detect the depth of the through hole. In this case, the iron core body is correctly oriented, preventing the distance sensor from sending an electrical signal to the first rotary cylinder, thus preventing the first rotary cylinder from rotating the second clamping cylinder. When the end of the iron core body with the through hole faces away from the distance sensor, the distance sensor cannot detect the depth of the through hole, and it sends an electrical signal to the first rotary cylinder, which then rotates the second clamping cylinder. The second clamping cylinder adjusts the orientation of the iron core body during clamping, ensuring accurate orientation for each iron core body and facilitating subsequent assembly. The first and second clamping cylinders are positioned at the same horizontal level, allowing for reliable simultaneous clamping of two iron core bodies without any missed clamping.
[0009] Preferably, the iron core rotating assembly includes a second bracket and a third bracket. The second bracket is provided with an alignment cylinder and a photoelectric sensor, and a second placement groove for placing the iron core body is provided on the second bracket. The end of the alignment cylinder is positioned directly opposite the second placement groove. The third bracket is provided with a second rotating cylinder, and a third clamping cylinder is fixedly connected to the rotating head of the second rotating cylinder.
[0010] The end of the iron core body where the cylindrical pin is installed has a hole and a notch. The cylindrical pin is installed in the hole, and a steel plate is installed in the notch. The notch and the hole are set perpendicular to each other. Since the hole orientation of the iron core body transported from the feeding line is random, the second rotary cylinder is used to adjust the hole orientation of the iron core body so that the hole is set vertically upward, which facilitates the pressing of the cylindrical pin later. When the iron core body is transported to the second placement groove, the alignment cylinder first pushes the iron core body to move it closer to the third clamping cylinder; at the same time, the photoelectric sensor starts to work. When the photoelectric sensor is aligned with the notch on the iron core body, the hole orientation of the iron core body is accurate. At this time, the photoelectric sensor does not send an electrical signal to the second rotary cylinder, so the third clamping cylinder will not rotate. When the photoelectric sensor is misaligned with the notch on the iron core body, the hole of the iron core body is not set vertically upward. At this time, the photoelectric sensor sends an electrical signal to the second rotary cylinder, which drives the third clamping cylinder to rotate, thereby adjusting the hole orientation of the iron core body.
[0011] Preferably, the pressing pin assembly further includes a fourth bracket, on which a vertically arranged third slide rail is provided; a first slider is provided on the third slide rail, and a pressing pin cylinder is provided at the top of the fourth bracket, with the piston shaft of the pressing pin cylinder connected to the first slider; a pin is provided on the lower end face of the first slider and fixedly connected thereto; a second slider is also provided on the third slide rail and is located below the first slider; a pressing pin head is provided on the second slider and fixedly connected thereto; a first adjusting screw for adjusting height is provided on the fourth bracket, and the first adjusting screw is arranged adjacent to the lower end face of the second slider.
[0012] Before stamping the cylindrical pin, the vertical height of the pin-pressing head needs to be adjusted in advance. By rotating the first adjusting screw, the pin-pressing head is positioned close to the iron core body on the transfer fixture. This allows the pin-pressing head to better guide the cylindrical pin, making the pin pressing smoother. When the pin-pressing cylinder operates, it pushes the first slider downward, causing the ejector pin to extend into the pin-pressing head, thus pre-pressing the cylindrical pin into the iron core body. At this point, the cylindrical pin is not fully inserted into the hole in the iron core body, leaving space for the steel sheet to be installed later.
[0013] Preferably, the pressing pin head is provided with a positioning block, which is adjacent to the iron core body on the transfer device, and the bottom of the positioning block is hollow; the pressing pin head is hollow, and the top of the pressing pin head is provided with a feeding channel; an isolation cylinder is provided on the outer wall of the pressing pin head, and the isolation cylinder extends into the interior of the pressing pin head; a second adjusting screw is also provided on the fourth bracket, which is adjacent to the first slider; both the first adjusting screw and the second adjusting screw are threadedly connected to the fourth bracket; when the pressing pin cylinder pushes the first slider to move, the ejector pin moves synchronously to the bottom of the pressing pin head; a fourth cylinder is provided at the end of the transfer device away from the positioning block, and a first positioning rod is provided on the piston shaft of the fourth cylinder, and the fourth cylinder is mounted on the mounting bracket.
[0014] By setting a positioning block, the cylindrical pins emerging from the pressing head are further guided, ensuring that the cylindrical pins can be pre-pressed into the holes of the iron core body. By setting an isolation cylinder, new cylindrical pins can be prevented from sliding into the pressing head from the feed channel during pressing, thus allowing for continuous pressing of cylindrical pins sequentially. By adjusting the second adjusting screw, the descent height of the first slider can be limited; thereby precisely adjusting the depth of the ejector pin inserted into the pressing head, the depth of the cylindrical pin pressed into the iron core body can be precisely controlled, facilitating subsequent assembly of steel sheets. By setting a first positioning rod to fix the iron core body, the end of the iron core body will not tilt relative to the conveyor when stamping the cylindrical pins, making the stamping process of the cylindrical pins more reliable.
[0015] Preferably, the steel sheet feeding assembly further includes a feeding track, a limiting plate, and a third pusher block; the feeding track is mounted on the first vibrator, and the grooves on the feeding track and the grooves on the steel sheet guide rail are arranged on the same axis; a fifth bracket is provided directly above the feeding track, and a pushing cylinder is provided on the fifth bracket, with a first pusher block on the piston shaft of the pushing cylinder; a sixth bracket is provided between the fifth bracket and the synchronous belt assembly, and a lifting cylinder is provided on the sixth bracket, with a steel sheet guide rail on the piston shaft of the lifting cylinder; positioning cylinders are arranged in pairs on both sides of the steel sheet guide rail, with a second pusher block on the piston shaft of the positioning cylinder; a baffle cylinder is located on the side of the steel sheet guide rail and away from the pushing cylinder, with a third pusher block on the piston shaft of the baffle cylinder.
[0016] The first vibrator starts working, transporting the steel sheet from the feeding track to the steel sheet guide rail. At this time, the lifting cylinder is in a retracted state, and the steel sheet guide rail and the feeding track are at the same horizontal level. Under the action of the first vibrator, the steel sheet automatically moves to the steel sheet guide rail. Then, the positioning cylinder controls the second push block to limit the steel sheet to the left and right, thereby aligning the steel sheet with the notch on the iron core body. Simultaneously, the baffle cylinder controls the third push block to extend, thus preventing further movement of the steel sheet. When the end of the steel sheet is in contact with the third push block, it indicates that the steel sheet is now completely on the steel sheet guide rail. Then, the lifting cylinder controls the steel sheet guide rail to rise, and the baffle cylinder controls the third push block to retract, so the end of the steel sheet facing the iron core body is no longer limited. Then, the pushing cylinder starts working, pushing the first push block, which pushes the steel sheet into the notch in the iron core body. Through the cooperation of the lifting cylinder and the baffle cylinder, steel sheets can be continuously transported to the steel sheet guide rail sequentially, resulting in higher assembly efficiency.
[0017] Preferably, when the steel sheet guide rail rises, the bottom of the first push block is flush with the groove on the steel sheet guide rail; the third push block is provided with a clearance groove, the outline of which matches the outline of the steel sheet; the end of the steel sheet guide rail is provided with a limiting plate fixedly connected thereto, the lower end face of the limiting plate is in contact with the upper end face of the third push block; the end of the synchronous belt assembly away from the steel sheet guide rail is provided with a fifth cylinder, the piston shaft of the fifth cylinder is provided with a second positioning rod, and the fifth cylinder is mounted on a mounting bracket.
[0018] By incorporating a clearance groove, the third pusher retracts, aligning the clearance groove with the groove on the steel sheet guide rail, allowing the steel sheet to move smoothly into the notch in the core body. The third pusher also facilitates blocking the steel sheet, ensuring only one sheet is transported at a time, preventing interference between them. A limiting plate restricts the upper surface of the steel sheet, preventing it from detaching from the guide rail during pressing. Finally, a fifth cylinder pushes the second positioning rod, axially limiting the core body and reliably pressing the steel sheet into the notch.
[0019] Preferably, the snap ring assembly further includes a seventh bracket and an eighth bracket. The top of the seventh bracket is provided with a cylindrical pin pressing cylinder and a first cylinder. The cylindrical pin pressing cylinder is positioned above the steel sheet feeding assembly. The piston shaft of the first cylinder is provided with a snap ring pressing block. The snap ring pressing block is provided with a third placement groove for placing the snap ring. The outer contour of the third placement groove matches the outer contour of the snap ring. Several evenly distributed magnets are provided in the third placement groove. The eighth bracket is provided with a second vibrator. The second vibrator is provided with a transport track for placing the snap ring. The end of the transport track is flush with the side wall of the snap ring pressing block.
[0020] After the steel sheets are assembled into the core body, the core body is positioned directly below the cylindrical pin clamping cylinder of the seventh bracket. The cylinder then presses the cylindrical pin fully into the hole in the core body, allowing it to pass through the steel sheet and securely connect to the core body. After the cylindrical pin is clamped, the transfer device moves towards the first cylinder, and the second vibrator transports the retaining ring closer to the retaining ring clamping block. When the retaining ring is adjacent to the third placement groove, it is attracted to the groove by a magnet. Then, the first cylinder lowers the retaining ring clamping block, locking the retaining ring into the groove in the core body. As the clamping block descends, the third placement groove and the retaining ring on the transport track are misaligned, separating the new retaining ring. When the first cylinder resets the clamping block, the new retaining ring is attracted to the third placement groove, and the new assembly begins.
[0021] Preferably, the seventh bracket is provided with a guide plate, and a sixth cylinder is fixedly connected to the bottom of the guide plate. The piston shaft of the sixth cylinder is located near the end of the iron core body.
[0022] The piston shaft of the sixth cylinder presses down on the iron core body, thereby positioning the iron core body and preventing the end of the iron core body from tilting relative to the conveyor when installing the snap ring.
[0023] Compared with existing technologies, this invention has the following advantages: The invention uses a first and second gripping cylinder on a feeding robot to simultaneously grip two iron core bodies, resulting in higher feeding efficiency. The orientation of the iron core bodies is adjusted by a first rotating cylinder, and the orientation of the holes in the iron core bodies is adjusted by a second rotating cylinder, making the placement of the iron core bodies more accurate and facilitating the subsequent assembly of cylindrical pins and steel sheets. A pin-pressing assembly pre-presses the cylindrical pin halfway into the iron core body, then a steel sheet feeding assembly installs the steel sheet into place, followed by a cylindrical pin-pressing cylinder fully pressing in the cylindrical pin. The cylindrical pin and steel sheet can be continuously and automatically installed with precise positioning and reliable installation. Finally, a snap ring pressing assembly quickly presses in the snap ring, ensuring stable snap ring insertion. Therefore, this invention offers high automatic assembly efficiency, precise positioning, and continuous installation, significantly increasing the production capacity of iron core assemblies.

[0030] The snap ring assembly 6 further includes a seventh bracket 64 and an eighth bracket 65. The top of the seventh bracket 64 is equipped with a cylindrical pin pressing cylinder 14 and a first cylinder 61. The cylindrical pin pressing cylinder 14 is positioned above the steel sheet feeding assembly 5. A snap ring pressing block 62 is mounted on the piston shaft of the first cylinder 61. The snap ring pressing block 62 has a third placement groove 66 for placing the snap ring, the outer contour of which matches the outer contour of the snap ring. Several evenly distributed magnets 63 are arranged within the third placement groove 66. A second vibrator 67 is mounted on the eighth bracket 65. The second vibrator 67 has a transport track 68 for placing the snap ring, the end of which is flush with the side wall of the snap ring pressing block 62. A guide plate 17 is mounted on the seventh bracket 64. A sixth cylinder 15 is fixedly connected to the bottom of the guide plate 17, the piston shaft of which is positioned near the end of the iron core body. The specific operation process of this embodiment is as follows: the iron core body is sequentially transported into the first placement groove 81 by the feeding assembly line 8, and then the orientation is detected by the distance sensor 82. The end of the iron core body with the slot has a through hole. When the through hole of the iron core body is directly facing the distance sensor 82, the distance sensor 82 can detect the depth of the through hole of the iron core body. At this time, the orientation of the iron core body is accurate, so the distance sensor 82 will not send an electrical signal to the first rotary cylinder 39, and the first rotary cylinder 39 will not drive the second clamping cylinder 311 to rotate. When the end of the iron core body with the through hole is facing away from the distance sensor 82, the distance sensor 82 cannot detect the depth of the through hole of the iron core body. The distance sensor 82 will then send an electrical signal to the first rotary cylinder 39, and the first rotary cylinder 39 will drive the second clamping cylinder 311 to rotate. The second clamping cylinder 311 can adjust the orientation of the iron core body when clamping it, so that the orientation of each iron core body is accurate, which facilitates subsequent assembly.
[0031] Next, the loading robot assembly 3 controls the first gripping cylinder 310 and the second gripping cylinder 311 to work synchronously. The second gripping cylinder 311 grips the iron core body into the second placement groove 75 of the iron core rotating assembly 7, and the first gripping cylinder 310 grips the iron core body onto the transfer carrier 22 of the transfer synchronous belt assembly 2. The end of the iron core body where the cylindrical pin is installed has a hole and a notch. The cylindrical pin is installed in the hole, and a steel plate is installed in the notch. The notch and the hole are set perpendicular to each other. Since the hole orientation of the iron core body transported from the loading assembly line 8 is random, it is necessary to adjust the hole orientation of the iron core body by using the second rotating cylinder 76 so that the hole of the iron core body is set vertically upward, which is convenient for pressing the cylindrical pin later. When the iron core body is transported to the second placement groove 75, the alignment cylinder 73 first pushes the iron core body closer to the third clamping cylinder 77; simultaneously, the photoelectric sensor 74 starts working. When the photoelectric sensor 74 is aligned with the notch on the iron core body, the hole orientation of the iron core body is accurate. At this time, the photoelectric sensor 74 will not send an electrical signal to the second rotating cylinder 76, so the third clamping cylinder 77 will not rotate. When the photoelectric sensor 74 is misaligned with the notch on the iron core body, the hole orientation of the iron core body is not vertically upward; at this time, the photoelectric sensor 74 will send an electrical signal to the second rotating cylinder 76, which will then drive the third clamping cylinder 77 to rotate, thereby adjusting the hole orientation of the iron core body.
[0032] After the iron core body is transported to the transfer fixture 22 of the synchronous belt assembly 2, the pressing pin assembly 4 begins to work. Before pressing the cylindrical pin, the vertical height of the pressing pin head 42 needs to be adjusted in advance. By rotating the first adjusting screw 49, the pressing pin head 42 is positioned close to the iron core body on the transfer fixture 22. This allows the pressing pin head 42 to better guide the cylindrical pin, making the pressing of the cylindrical pin smoother. When the pressing pin cylinder 41 works, it pushes the first slider 46 down, and the ejector pin 47 extends into the pressing pin head 42, thus pressing the cylindrical pin in the pressing pin head 42 into the iron core body in advance. At this time, the cylindrical pin is not fully inserted into the hole of the iron core body, leaving space for the steel sheet to be installed later.
[0033] Next, the transfer device 22 transports the iron core body to the station where the steel sheet feeding assembly 5 is located; the first vibrator 51 starts working to transport the steel sheet from the feeding track 57 to the steel sheet guide rail 55; at this time, the lifting cylinder 56 is in the retracted state, and the steel sheet guide rail 55 and the feeding track 57 are at the same horizontal height. Under the action of the first vibrator 51, the steel sheet automatically moves to the steel sheet guide rail 55; at this time, the positioning cylinder 53 works to control the second push block 511 to limit the steel sheet to the left and right, so that the steel sheet is aligned with the notch on the iron core body. At the same time, the baffle cylinder 54 controls the third push block 512 to push out, thereby preventing the steel sheet from moving further. When the end of the steel sheet is in contact with the third push block 512, it proves that the steel sheet is completely on the steel sheet guide rail 55. Then, the lifting cylinder 56 controls the steel sheet guide rail 55 to rise, and the baffle cylinder 54 controls the third push block 512 to retract, so that the end of the steel sheet facing the iron core body will lose its limit. Then, the pushing cylinder 52 starts to work, and the pushing cylinder 52 pushes the first push block 510, so that the first push block 510 will push the steel sheet into the notch of the iron core body.
[0034] After the steel sheet is assembled into the core body, the core body is positioned directly below the cylindrical pin pressing cylinder 14 of the seventh bracket 64. The cylindrical pin pressing cylinder 14 then presses the cylindrical pin completely into the hole in the core body, allowing it to pass through the steel sheet and securely connect to the core body. After the cylindrical pin is pressed in, the transfer device 22 moves towards the first cylinder 61, and the second vibrator 67 transports the retaining ring closer to the retaining ring pressing block 62. When the retaining ring is adjacent to the third placement groove 66, it is attracted to the third placement groove 66 by the magnet 63. Then, the first cylinder 61 controls the retaining ring pressing block 62 to descend, allowing the retaining ring to engage with the groove in the core body. As the retaining ring pressing block 62 descends, the third placement groove 66 and the retaining ring on the transport track 68 are misaligned, separating the new retaining ring. When the first cylinder 61 controls the retaining ring pressing block 62 to reset, the new retaining ring is attracted to the third placement groove 66, and the new assembly begins. The piston shaft of the sixth cylinder 15 presses down on the iron core body, thereby positioning the iron core body and preventing the end of the iron core body from tilting relative to the flow carrier 22 when the snap ring is installed.
