Description

Technical Field

[0001] This application relates to the field of magnetic ring inductor processing, and more specifically, to a bushing machine used in magnetic ring inductors. Background Technology

[0002] A magnetic ring inductor is an inductor made by winding wire around a toroidal magnetic core. Its core function is to convert electrical energy into magnetic energy using the principle of electromagnetic induction. When current flows through the magnetic ring inductor, a magnetic field is generated, converting electrical energy into stored magnetic energy. When the current changes, the magnetic field also changes, generating an induced electromotive force, which in turn converts magnetic energy back into electrical energy.

[0003] Because the core of a magnetic ring inductor is easily scratched by its leads during transportation, it needs to be protected by an outer casing. The casing also serves to fix the enameled wire to the core, preventing displacement in vibration or unstable environments and maintaining stable inductor performance.

[0004] Currently, the process of cutting the tube body into sections using a tube cutting machine and then inserting the magnetic ring inductor into the tube body is mainly done manually. A heat pipe machine is then used to heat the inserted magnetic ring inductor, causing the tube body to tighten and tightly wrap around the magnetic ring inductor, preventing it from detaching. However, manual operation leads to low overall tube-sleeving efficiency, and human error can result in poor quality, affecting the speed and quality of magnetic ring inductor sleeve processing.

[0071] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0072] Reference Figure 1-27 ,

[0073] A bushing machine for use with magnetic ring inductors 8 includes: a multi-station turntable 1, a power unit 2, a feeding device 3, a tube cutting device 4, a heating device 5, a testing device 6, and a main support 7. The multi-station turntable 1, the power unit 2, the feeding device 3, the tube cutting device 4, the heating device 5, the testing device 6, and the main support 7 are all connected to the main support 7.

[0074] The power unit 2 drives the multi-station turntable 1 to rotate, causing the multi-station turntable 1 to rotate sequentially to the feeding device 3, the pipe cutting device 4, the heating device 5, and the detection device 6. The power unit 2 is an electric motor.

[0075] The feeding device 3 is used to place the magnetic ring inductor 8 onto the multi-station turntable 1. The feeding device 3 includes a feeding plate 31 and a first pneumatic gripper 32. The feeding plate 31 has multiple grooves 311, in which the magnetic ring inductor 8 is placed. The first pneumatic gripper 32 simultaneously grips multiple magnetic ring inductors 8 and transfers them onto the multi-station turntable 1. The multiple grooves 311 are distributed in a rectangular array on the push plate 443. The multi-station turntable 1 has receiving slots 11 for holding the magnetic ring inductors 8, and multiple receiving slots 11 are provided. Preferably, the multi-station turntable 1 is a hexagonal disc, and the receiving slots 11 are located on the edges of the hexagonal disc, allowing the multi-station turntable 1 to simultaneously transfer multiple magnetic ring inductors 8. The first pneumatic gripper 32 is driven to move its position by a robotic arm or a moving arm 4452.

[0076] The pipe cutting device 4 is used to cut the sleeve into multiple pipe segments 9 and fit the sleeve onto the magnetic ring inductor 8 on the multi-station turntable 1. The heating device 5 is used to heat the pipe segments 9 on the magnetic ring inductor 8, so that the pipe segments 9 tighten and wrap around the magnetic ring inductor 8, completing the processing of the magnetic ring inductor 8. The detection device 6 is used to detect the magnetic ring inductor 8 wrapping the pipe segments 9. In summary, this application realizes the automatic processing of the magnetic ring inductor 8.

[0077] Specifically, the pipe cutting device 4 includes a driving component 41, a cutting component 42, an insert rod 43, and a transfer component 44. The driving component 41 delivers the sleeve to the cutting component 42. The sleeve is wound around a winding roller 411. The driving component 41 pulls the sleeve wound on the winding roller 411 outwards and delivers it to the position of the cutting component 42, where the cutting component 42 cuts the sleeve to obtain a pipe segment 9. The insert rod 43 is positioned above the cutting component 42. When the driving component 41 delivers the sleeve to the cutting component 42, the sleeve is inserted into the insert rod 43. The insert rod 43 positions the upper part of the sleeve and provides support at both ends of the cutting position during cutting, allowing the cutting component 42 to cut the sleeve more effectively. The transfer component 44 delivers the pipe segment 9 to the multi-station turntable 1.

[0078] The drive unit 41 includes multiple guide rollers 412, a drive roller 413, and a first motor 414 for rotating the drive roller 413. The multiple guide rollers 412 guide the sleeve, pulling it from the winding roller 411 to the position of the drive roller 413, and then the drive roller 413 drives the sleeve, moving it to the position of the cutter 42. The drive roller 413 uses a pair of rollers to clamp the sleeve for driving.

[0079] The pipe cutting device 4 further includes a mounting platform 49. The cutting element 42 and the insertion rod 43 are both mounted on the mounting platform 49. The mounting platform 49 has a through hole 491 with a diameter larger than the outer diameter of the sleeve. The mounting platform 49 also has an enlarged hole, the axis of which matches the axis of the through hole 491. A driving element 41 is located below the mounting platform 49. A driving roller 413 drives the sleeve upwards from the enlarged hole position, moving the sleeve to the through hole 491 and exiting above the mounting platform 49. The enlarged hole facilitates the insertion of the sleeve into the through hole 491. The insertion rod 43 is located above the through hole 491. After the sleeve exits through the through hole 491, it partially fits into the insertion rod 43. A cutting gap exists between the insertion rod 43 and the upper end face of the mounting platform 49. The cutting element 42 is at least partially disposed within this cutting gap. The cutting element 42 cuts the sleeve at the cutting gap, obtaining a pipe segment 9 fitted onto the insertion rod 43. Then, the transfer component 44 is used to transfer the tube segment 9 on the insertion rod 43 to the magnetic ring inductor 8 on the multi-station turntable, thus achieving the fitting of the tube segment 9 onto the magnetic ring inductor 8. Multiple guide rollers 412 are rotatably connected to the mounting platform 49. The rotation of the guide rollers 412 is used to guide the sleeve.

[0080] Specifically, the transfer component 44 transfers the pipe segment 9 on the insertion rod 43 to the multi-station transfer plate by utilizing the following components: a moving structure 441, a moving frame 442, a pusher plate 443, a receiving plate 444, a transfer robot 445, and a control structure that drives the insertion rod 43 and the pusher plate 443 to move respectively.

[0081] The pusher plate 443 contacts the outer wall of the insertion rod 43, and the pusher plate 443 partially overlaps with the pipe segment 9 on the insertion rod 43. Therefore, when the pusher plate 443 moves downward relative to the insertion rod 43, it can push the pipe segment 9 downward, disengaging it from the insertion rod 43. Specifically, the pusher plate 443 has a through hole 4431 into which the insertion rod 43 is inserted. The pusher plate 443 and the insertion rod 43 are slidably connected, allowing the pusher plate to better push the pipe segment 9 downward.

[0082] The moving structure 441 is used to drive the moving frame 442 to move; the insertion rod 43 is slidably connected to the moving frame 442, and the insertion rod 43 and the rotating frame form a synchronously moving whole. Additionally, the pusher plate 443 is connected to the insertion rod 43. The receiving plate 444 is used to receive material, catching the pipe segment 9 that has detached from the insertion rod 43. The moving trajectory of the receiving plate 444 coincides with that of the insertion rod 43, so the insertion rod 43 can move to the position of the receiving plate 444 and push the pipe segment 9 on the insertion rod 43 onto the receiving plate 444. The transfer robot 445 is positioned between the receiving plate 444 and the multi-station rotating plate. The transfer robot 445 removes the pipe segment 9 from the receiving plate 444 and places it onto the magnetic ring inductor 8 on the multi-station turntable 1.

[0083] In one possible implementation of the mobile structure 441, the mobile structure 441 directly adopts a robotic arm, and the mobile frame 442 is connected to the robotic arm.

[0084] In one possible implementation of the control structure, the control structure can directly adopt multiple electric push rods, all of which are connected to the moving frame 442. The output ends of some electric push rods are connected to the insertion rod 43, and the output ends of some electric push rods are connected to the push plate 443. The electric push rods directly drive the insertion rod 43 and the push plate 443 to move up and down.

[0085] In another possible implementation of the moving structure 441, the moving structure 441 includes a rotary motor 4411, which is mounted on the mounting platform 49. The output end of the rotary motor 4411 is connected to the moving frame 442. The rotary motor 4411 drives the moving frame 442 to rotate, and when the moving frame 442 rotates, the insertion rod 43 can rotate to above the receiving plate 444.

[0086] In another possible implementation of the control structure, the control structure includes a transmission rod 45, an elastic component 46, and a lifting structure 47. The elastic component 46 is a spring. Multiple elastic components 46 are provided, positioned on the transmission rod 45 and the insertion rod 43, so that both the transmission rod 45 and the insertion rod 43 are subjected to an upward rebound force. The insertion rod 43 has a first limiting portion 433, and the transmission rod 45 has a second limiting portion 451. Both the first limiting portion 433 and the second limiting portion 451 are located away from the worktable. Some of the elastic components 46 are positioned between the first limiting portion 433 and the mounting platform 49, and other elastic components are positioned between the second limiting portion 451 and the mounting platform 49, so that both the transmission rod 45 and the insertion rod 43 are subjected to an upward rebound force. The lifting structure 47 uses a cylinder. However, because the cylinder is relatively large, its installation on the moving frame 442 would result in a large space occupation, or the moving frame 442 would become too heavy to rotate. The cylinder requires an external air source, but the rotation of the cylinder with the rotating frame makes it difficult to connect the cylinder's piping to the air source. Therefore, a scheme is used to fix the lifting structure 47 and rotate the insertion rod 43 and transmission rod 45 to drive the insertion rod 43 and transmission rod 45 downward. The specific scheme is as follows:

[0087] A linear drive structure is also provided at the position of the receiving plate 444. The linear drive structure is used to move the receiving plate 444 to facilitate the receiving plate 444 to better receive the pipe segment 9 from the insertion rod 43. The linear drive structure can be a linear module.

[0088] The transmission rod 45 is fixedly connected to the pusher plate 443. A fixing frame 48 is provided on the mounting platform 49, and the lifting structure 47 is provided on the fixing frame 48. Multiple sets of insertion rods 43 and transmission rods 45 are provided on the rotating frame, wherein some of the insertion rods 43 are located above the through hole 491, and other parts of the insertion rods 43 are located above the receiving plate 444. When the moving frame 442 rotates, the insertion rods 43 and transmission rods 45 always switch between positions above the through hole 491 and above the receiving plate 444. Multiple lifting structures 47 are provided, some of which match the position of the insertion rod 43 at the through hole 491; other parts of the lifting structures 47 match the positions of the insertion rod 43 and transmission rod 45 at the receiving plate 444. To be precise, when the output end of part of the lifting structure 47 moves downward, it will contact the first limiting part 433 of the insertion rod 43 above the perforation 491, causing the insertion rod 43 to move downward. The elastic component 46 is compressed, so the insertion rod 43 can move downward to a position flush with the mounting platform 49 or partially enter the perforation 491. This allows the sleeve to be quickly and stably fitted onto the insertion rod 43. Then, the output end of the lifting structure 47 returns to its original position, and the elastic component 46 moves the insertion rod 43 upward through the first limiting part 433. The insertion rod 43 moves upward to a position that forms a cutting gap with the mounting platform 49. Then, the cutting component 42 cuts the sleeve, and the moving structure 441 drives the moving frame 442 to rotate. When the output end of another part of the lifting structure 47 moves downward, it will simultaneously contact the first limiting part 433 of the insertion rod 43 above the receiving plate 444 and the second limiting part 451 of the transmission rod 45, causing the insertion rod 43 and the transmission rod 45 to move downward simultaneously or individually.

[0089] In the specific design of the receiving plate 444, multiple protrusions 4441 are provided on the receiving plate 444, and the outer diameter of the protrusions 4441 is smaller than the inner diameter of the pipe segment 9. Thus, when the pipe segment 9 is pushed into the receiving plate 444 by the insert rod 43, the pipe segment 9 fits onto the protrusions 4441. A gap exists between the top surface of the protrusions 4441 and the bottom surface of the insert rod 43. A displacement structure is provided at the receiving plate 444 to allow the receiving plate 444 to move. The gap is to allow the insert rod 43 to move relative to the protrusions 4441 on the receiving plate 444, avoiding interference between the insert rod 43 and the protrusions 4441. The insertion of the pipe segment 9 into the protrusions 4441 facilitates the removal of the pipe segment 9 from the receiving plate 444 by the transfer robot 445.

[0090] The transfer manipulator 445 employs a combination of a second pneumatic gripper and a moving arm 4452. The moving arm 4452 can be a robotic arm or a two-axis or three-axis slide formed by combining two or more first linear modules. The second pneumatic gripper clamps multiple pipe segments 9 on the protrusion 4441. Therefore, placing the pipe segments 9 on the protrusion facilitates the removal of the multiple pipe segments 9 by the second pneumatic gripper. The arrangement of the multiple protrusions 4441 is the same as the arrangement of the receiving slots 11 on the multi-station turntable 1, thus facilitating the second pneumatic gripper to insert multiple pipes onto the magnetic ring inductor 8. The protrusion 4441 is a cylindrical protrusion formed on the receiving plate 444. When the insertion rod 43 rotates above the receiving plate 444, the pusher plate 443 moves downward, directly pushing the pipe segments 9 on the insertion rod 43 onto the protrusion 4441. The second pneumatic gripper can also be replaced by a picking rod 4451. Multiple picking rods 4451 are provided, and all of them are connected to the moving arm 4452. The moving arm 4452 moves the picking rod 4451 down to the protrusion 4441 of the receiving plate 444, and then inserts it into the tube section 9 of the protrusion 4441. Then the moving arm 4452 moves the picking rod 4451 up and moves it to the multi-station turntable 1. The picking rod 4451 puts the tube section 9 onto the magnetic ring inductor 8.

[0091] Specifically, the cutting component 42 includes a cutter 421 and a pushing structure 422; the cutter 421 is angled; the pushing structure 422 is used to move the cutter 421 to the cutting gap. The pushing structure 422 is a cylinder. The cutter 421 is mounted on a blade holder 423, which is slidably connected to the mounting platform 49. The angled arrangement of the cutter 421 means that the cutting edge of the cutter 421 and the direction in which the pushing structure 422 moves the cutter 421 have an angle of 10-80°, preferably 30-50°. The angled arrangement of the cutter 421 makes it easier to cut the sleeve.

[0092] Specifically, the heating device 5 includes a first heating element 51 with a first heating surface 511 and a second heating element 52 with a second heating surface 521; the tube segment 9 of the magnetic ring inductor 8 is located between the first heating surface 511 and the second heating surface 521; both the first heating surface 511 and the second heating surface 521 have multiple hot air outlets 53. Both the first heating element 51 and the second heating element 52 are block structures. The hot air outlets 53 can be connected to external hot air equipment. Hot air discharged from the hot air outlets 53 directly contacts the tube segment 9, causing the tube segment 9 to tighten upon heating and tightly wrap around the magnetic ring inductor 8.

[0093] The heating device 5 may further include a lifting structure 54, which is used to move the first heating element 51 and the second heating element 52 upward and downward. The lifting structure 54 includes a cylinder, which moves the first heating element 51 and the second heating element 52 upward and downward. During the rotation of the multi-station turntable 1, the lifting structure 54 moves the first heating element 51 and the second heating element 52 upward. When the multi-station turntable 1 stops rotating, the lifting structure 54 moves the first heating element 51 and the second heating element 52 downward and heats the magnetic ring inductor 8 on the multi-station turntable 1.

[0094] The heating device 5 may further include a connecting frame 55 between the first heating component 51 and the second heating component 52. The first heating component 51 and the second heating component 52 are fixed by the connecting frame 55. A pressing structure 56 is provided on the connecting frame 55, and the pressing structure 56 has a pressing surface 561. The lifting structure 54 is also used to drive the pressing structure 56 to move downward. A plurality of slots 562 are provided on the pressing surface 561. The position of the slots 562 matches the position of the magnetic ring inductor 8, so that the downward movement of the pressing structure 56 can use the slots 562 to press the pipe segment 9 and tighten the top opening of the pipe segment 9.

[0095] Specifically, the detection device 6 includes an industrial camera 61 and a lighting lamp 62; both the industrial camera 61 and the lighting lamp 62 are located on the edge of the multi-station turntable 1. The industrial camera 61 performs visual inspection on the magnetic ring inductor 8 to detect whether the quality of the magnetic ring inductor 8 meets the requirements.

[0096] More specifically, the detection device 6 also includes a second linear module 63, a third linear module 64, a second motor 65, a third pneumatic gripper 66, and a gripper mounting base 67. Both the second linear module 63 and the third linear module 64 are connected to the main support 7. The second linear module 63 drives the movement of the lighting lamp 62, and the third linear module 64 drives the movement of the gripper mounting base 67. The second motor 65 is mounted on the third linear module 64 and drives the gripper support to rotate. The third pneumatic gripper 66 is connected to the gripper support. Therefore, the third pneumatic gripper 66 can move and rotate, allowing it to grip and move the magnetic ring inductor 8 on the multi-station turntable 1 to the position of the lighting lamp 62. Then, the second motor 65 rotates the third pneumatic gripper 66, so that the magnetic ring inductor 8 on the third pneumatic gripper 66 faces the lighting lamp 62 and the industrial camera 61, making the quality detection of the magnetic ring inductor 8 more accurate.

[0097] In other embodiments, a venting chamber 431 and an exhaust outlet 432 are formed in the middle of the insertion rod 43. When the insertion rod 43 is inserted into the sleeve, the venting chamber 431 communicates with the cavity of the sleeve through the exhaust outlet 432. An air injection device is also provided on the mounting platform 49. The air injection device is used to inject air into the venting chamber 431. The air injection device includes an air pump and an air pipe, and the air pipe connects the exhaust port of the air pump to the venting chamber 431. A pressure relief valve is provided on the air pipe. When the insertion rod 43 is inserted into the sleeve, the air injection device injects air into the communicating chamber and into the cavity of the sleeve, which helps maintain the sleeve in a normal state and avoids the sleeve becoming deflated. This also improves the stability of the cutting device 42 when cutting the sleeve.

[0098] When the cutting element 42 cuts the sleeve, the air injection element blows air onto the cutting blade 421, which helps to clean the chips on the cutting blade 421 and better maintain the quality of the cutting blade 421 itself for a longer period of time.

[0099] Specifically, the air injection component is preferably fixed on the movable frame 442. Therefore, when the movable frame 442 rotates or moves, the air injection component can better ensure its communication with the ventilation chamber 431 and inject air into the ventilation chamber 431.
