Abstract
Description
Technical Field
[0001] This invention relates to the field of horizontal inductor winding machine technology, and more specifically to a feeding device for a horizontal inductor winding machine. Background Technology
[0002] Conventional surface mount inductor winding machines use a disc-type feeding mechanism to feed the surface mount magnetic cores. After feeding, the cores enter the inductor mounting fixture and are then rotated onto a smooth guide rail and vacuum suction for further feeding. Following feeding, subsequent processes include winding, cutting off excess winding, welding, and recycling of the wound surface mount inductors. This disc-type + smooth guide rail + vacuum suction method is only suitable for rectangular ceramic cores and cannot be used for other products. However, for horizontal inductors, since both ends of the magnetic core are connected to an iron core shaft, and the two free ends of the coil after winding on the magnetic core are welded to the iron core shafts at both ends, the inventors found that the conventional surface mount inductor feeding method is not suitable. If manual feeding is used, it is time-consuming and labor-intensive, and the feeding positioning accuracy is not high, which affects the subsequent winding positioning quality. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a feeding device for a horizontal inductor winding machine, which can realize the feeding of horizontal inductors, save time and effort, and accurately position the feeding, so as to avoid affecting the winding quality of the horizontal inductors in the later stage.
[0004] To solve the above-mentioned technical problems of the present invention, the technical solution adopted by the present invention is as follows: A feeding device for a horizontal inductor winding machine, comprising: Workbench; The chain conveyor mechanism is placed horizontally on the workbench with its discharge end located next to the horizontal inductor mounting fixture, and is used to place and convey the horizontal inductor. The material loading and unloading mechanism is installed on the workbench and located at the discharge end of the chain conveyor mechanism. It is used to remove the horizontal inductor from the chain conveyor mechanism and install it onto the horizontal inductor mounting fixture of the winding machine.
[0005] Furthermore, the chain conveying mechanism includes: A chain feeder comprises a chain frame, a drive sprocket, a first driven sprocket, a second driven sprocket, a chain, and a chain drive motor. The chain frame is a horizontal strip structure, with one side fixedly connected to the workbench via a support frame. The chain is connected to the drive sprocket, the first driven sprocket, and the second driven sprocket. The drive sprocket, the first driven sprocket, and the second driven sprocket are all rotatably connected to the chain frame. The first driven sprocket and the second driven sprocket are located at both ends of the chain frame, and the drive sprocket is located below the first driven sprocket. The motor shaft of the chain drive motor is fixedly connected to the drive sprocket, and the chain drive motor is fixedly connected to the chain frame. Multiple placement racks are used to horizontally place multiple horizontal inductors. Each placement rack is installed on one of the outer chain plates of the chain, and when the chain travels to the top of the chain frame, the placement rack is higher than the top surface of the chain frame.
[0006] Furthermore, the placement frame adopts two angle steel-shaped support members. The two support members are symmetrically fixedly connected to a pair of outer chain plates with their backs to each other, and the distance between the vertical plates of the two support members is greater than the magnetic core of the horizontal inductor. Two V-shaped notches are symmetrically arranged on the top of the two support members. The two V-shaped notches are used to support the iron core shaft of the horizontal inductor.
[0007] Furthermore, the bottom of the base plate of the support member is fixedly connected to the outer chain plate by an inverted L-shaped vertical connector.
[0008] Furthermore, the chain frame includes: The central support component is a strip structure, and is fixedly connected to the support frame on the side near the center. The first sprocket mounting plate consists of two pieces, which are symmetrically fixedly connected to the horizontal sides of one end of the central support member and form a receiving space. The receiving space is used to rotatably connect the first driven sprocket and the driving sprocket. The second sprocket mounting plate consists of two pieces, which are symmetrically fixedly connected to the other horizontal sides of the central support member and form a second receiving space. The second receiving space is used to rotatably connect the second driven sprocket.
[0009] Furthermore, a detection sensor is installed on one side of the chain frame to determine the starting position of the chain conveying mechanism, and the probe of the detection sensor faces the placement frame.
[0010] Furthermore, the material loading and unloading mechanism includes: The lifting mechanism, installed at the end of the chain conveyor, is used to lift the horizontal inductor placed and conveyed on the chain conveyor away from the chain conveyor. A clamping mechanism, installed at one end of the cantilever and above the lifting mechanism, is used to clamp a horizontal inductor. A lifting mechanism is installed at the moving execution end of the horizontal moving mechanism. The other end of the cantilever is fixedly connected to the end of the lifting mechanism. After the lifting mechanism lifts the horizontal inductor, the iron core shaft of the horizontal inductor can be directly aligned with the clamping part of the horizontal inductor mounting fixture. A horizontal moving mechanism, mounted on the workbench, is used to move the cantilever toward the side of the horizontal inductor mounting fixture; A pushing mechanism, mounted on the cantilever, is used to push the iron core shaft of the horizontal inductor to the clamping part of the horizontal inductor mounting fixture for clamping and fixing.

The top of the two side panels is provided with two symmetrical V-shaped grooves, which can support and correct the iron core shaft of the horizontal inductor. A lifting slide cylinder is vertically mounted on the worktable, with its end fixedly connected to the lifting base. After the cylinder rod of the lifting slide cylinder extends, it lifts the horizontal inductor away from the placement frame of the chain conveyor mechanism through the U-shaped correction lifting frame.

A centering pusher is fixedly connected to the cantilever and faces the centering baffle. When the horizontal moving mechanism drives the cantilever to move horizontally, it drives the centering pusher to push the horizontal inductor placed on the placement rack toward one side of the centering baffle for centering.
[0014] Furthermore, the push mechanism includes: A bending push rod has a downward-facing fork at its front end. After multiple bends, the bending push rod positions the fork in front of the clamping part of the clamping mechanism. The fork can be engaged on the iron core shaft of the horizontal inductor and is located away from the horizontal inductor mounting fixture. When the fork moves toward the side of the horizontal inductor mounting fixture, it can abut against the magnetic core side to push the horizontal inductor into the clamping part of the horizontal inductor mounting fixture for the last distance of positioning and clamping. A sliding plate is fixedly connected to a push rod fixing seat. The push rod fixing seat is arranged on the side near the clamping mechanism. The rear end of the bent push rod is fixedly connected to the front end face of the push rod fixing seat. A push slider guide rail pair has a guide rail and a slider. The guide rail is fixedly connected to the side of the cantilever, and the slider is fixedly connected to a push sliding plate. The push cylinder has a cylinder seat and a cylinder rod. The cylinder seat is fixedly connected to the cantilever and located behind the guide rail. The cylinder rod is fixedly connected to the short plate of the L-shaped cylinder connecting plate.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] To address the issue that existing surface mount inductor winding machines cannot adapt to horizontal inductor winding, a completely new horizontal inductor feeding device is proposed. Specifically, a chain conveyor is used to space and transport horizontal inductors, and a material handling mechanism picks up the materials and transfers them to the horizontal inductor mounting fixtures. This allows for rapid feeding of horizontal inductors, saving time and labor, and ensuring accurate, stable, and reliable feeding. It avoids the problem of poor winding quality caused by poor feeding accuracy due to manual feeding.
[0019] Example 1: As Figure 1-18 As shown, a feeding device for a horizontal inductor winding machine includes a worktable 10, a chain conveyor mechanism 201, and a material loading mechanism 202. The chain conveyor mechanism 201 is horizontally placed on the workbench 10 with its discharge end located next to the horizontal inductor mounting fixture 30, and is used to place and convey the horizontal inductor 40. The material handling and loading mechanism 202 is installed on the workbench 10 and located at the discharge end of the chain conveyor mechanism 201, and is used to take out the horizontal inductor 40 from the chain conveyor mechanism 201 and install it onto the horizontal inductor mounting fixture 30 of the winding machine. The material handling and loading mechanism 202 is placed horizontally and perpendicular to the chain conveyor mechanism 201.
[0020] This application uses a chain conveyor mechanism to automatically place and transport horizontal inductors, and a material loading mechanism to take out the horizontal inductors placed and transported to the end and place them onto the horizontal inductor mounting fixture. This enables rapid loading of horizontal inductors, improves loading efficiency and accuracy, avoids the time and labor costs of manual loading, and avoids the winding quality problems caused by inaccurate loading.
[0021] The workbench 10 adopts a conventional workbench surface, with a rotary table 50 installed in the middle. It has the same rotary table structure as the existing surface mount inductor winding machine. The rotary table 50 extends out from the center and is fixed to the platform 60. The difference is that the clamps for holding the horizontal inductor 30 are different. The output rotating round table 501 of the rotary table 50 is equipped with a horizontal inductor mounting clamp 30, which rotates to the corresponding work position to perform the corresponding operation process.
[0022] The chain conveying mechanism 201 includes a chain feeder 2011 and a placement rack 2012; The chain feeder 2011 comprises a chain frame 20111, a drive sprocket 20112, a first driven sprocket 20113, a second driven sprocket 20114, a chain 20115, and a chain drive motor 20116. The chain frame 20111 has a horizontal strip structure. One side of the chain frame 20111 is fixedly connected to the workbench 10 via a support frame 20117. The chain 20115 is connected to the drive sprocket 20112, the first driven sprocket 20113, and the second driven sprocket 20114. The drive sprocket 20112 and the first driven sprocket 20111... 3. Both the first driven sprocket 20113 and the second driven sprocket 20114 are rotatably connected to the chain frame 20111. The first driven sprocket 20113 and the second driven sprocket 20114 are located at both ends of the chain frame 20111 and can expose the chain 20115 on the top surface of the chain frame 20111. The driving sprocket 20112 is located below the first driven sprocket 20113. The motor shaft of the chain drive motor 20116 (which acts as the rotation shaft of the driving sprocket 20112) is fixedly connected to the driving sprocket 20112. The chain drive motor 20116 is fixedly connected to the chain frame 20111. Chain 20115 includes inner chain plate 201151, outer chain plate 201152, pin, sleeve and roller 201153.
[0023] Multiple placement racks 2012 are used to horizontally place multiple horizontal inductors 40. Each placement rack 2012 is installed on one pair of outer chain plates 201152 of the chain 20115. One placement rack 2012 is arranged on each pair of outer chain plates 201152. When the chain 20115 travels to the top of the chain frame 20111, the placement rack 2012 is higher than the top surface of the chain frame 20111.
[0024] The mechanism consisting of a placement rack and a chain feeding mechanism enables the spaced placement and conveying of horizontal inductors, facilitating the interval operation of the next clamping and loading, simplifying cycle control, and enabling directional conveying of horizontal inductors.
[0025] In Embodiment 1 of this application, in order to facilitate the stable placement of the horizontal inductor, the placement rack 2012 adopts two angle steel-shaped support members 20121. The two support members 20121 are symmetrically fixedly connected to an outer chain plate 201152 with their backs to each other, and the distance between the vertical plates of the two support members 20121 is greater than the magnetic core of the horizontal inductor 40. Two V-shaped notches 20122 are symmetrically arranged on the top of each of the two support members 20121. The two V-shaped notches 20122 are used to support the iron core shaft of the horizontal inductor 40. The two symmetrical V-shaped notches 20122 can support the iron core shafts at both ends of the horizontal inductor 40, realizing the placement of the horizontal inductor. Moreover, the V-shaped notch structure can realize automatic centering and also facilitates the placement and removal of the horizontal inductor from the V-shaped notches. The angle steel-shaped support members are easy to install and provide stable support.
[0026] In Embodiment 1 of this application, in order to facilitate the stable connection of the support member to the outer chain plate, the bottom of the base plate of the support member 20121 is fixedly connected to the outer chain plate 201152 by an inverted L-shaped vertical connector 20123. Using this vertical connector, it is convenient to quickly and easily fix the support member to the outer chain plate. The top plate of the inverted L-shaped vertical connector 20123 is embedded in the positioning groove 20124 provided in the base plate of the support member 20121 and the base plate of the support member 20121 and the top plate of the vertical connector 20123 are locked together by bolts. The positioning groove can improve the symmetry of the V-shaped notch.
[0027] In Embodiment 1 of this application, the chain frame 20111 includes a central support member 201111, a first sprocket mounting plate 201112, and a second sprocket mounting plate 201113; The central support component 201111 is a strip structure, with a support frame 20117 fixedly connected near the center. Made of aluminum alloy profiles, it features a horizontal T-slot for easy connection to other sheet metal. The support frame 20117 is an L-shaped sheet metal structure. A T-nut is inserted into the T-slot on the side of the chain frame 20111, and then screws 20119, which mate with T-nuts 20118, are used to secure the support frame 20117 to the chain frame 20111. The top surface of the central support component 201111 is flat, supporting the top section of the chain 20115. Vertical through holes 20120 are provided where screws 20119 pass through the support frame 20117, facilitating height adjustment to accommodate the next process (centering, lifting, or clamping). The first sprocket mounting plate 201112 consists of two pieces, which are symmetrically fixedly connected to the horizontal sides of one end of the central support member 201111 and form a receiving space 201114. The receiving space 201114 is used to rotatably connect the first driven sprocket 20113 and the driving sprocket 20112. The first sprocket mounting plate 201112 is also fixedly connected to the chain frame 20111 by using a T-nut 20118 to be inserted into the T-slot on the side of the chain frame 20111 and then using a screw 20119 that mates with the T-nut 20118.
[0028] The second sprocket mounting plate 201113 consists of two pieces, which are symmetrically fixedly connected to the other horizontal sides of the middle support member 201111 and form a second receiving space 201115. The second receiving space 201115 is used to rotatably connect the second driven sprocket 20114. The second sprocket mounting plate 201113 is also fixedly connected to the chain frame 20111 by using a T-nut 20118 to be inserted into the T-slot on the side of the chain frame 20111 and then using a screw 20119 that mates with the T-nut 20118.
[0029] The chain frame, consisting of a central support made of profiles, two first sprocket mounting plates, and two second sprocket mounting plates, provides stable and reliable support and is easy and quick to install. The resulting two accommodating spaces facilitate the arrangement of sprockets. Furthermore, by loosening the screws and adjusting the first sprocket mounting plates and the two second sprocket mounting plates to move away from or closer to the central support, the chain tension can be adjusted. After adjustment, the screws can be tightened onto the T-nuts.
[0030] To facilitate the determination of the starting point of the chain conveyor mechanism 201, a detection sensor 2013 is installed on one side of the chain frame 20111 to determine the starting position of the chain conveyor mechanism 201. The probe of the detection sensor 2013 can face the placement frame 2012. The detection sensor 2013 is a distance sensor and is fixedly connected to the side wall of the chain frame 20111 through a bent mounting plate 2015 (using T-bolts and screws for fixed connection). The bent mounting plate 2015 is placed at an angle, and the height of the detection sensor can be adjusted by adjusting the placement angle (the larger the acute angle relative to the horizontal, the higher the installation height). A positioning strip 2014 is provided on the top surface of the chain frame 20111. The positioning strip 2014 is located on one side of the chain and is arranged opposite to the detection sensor 2013. The positioning strip enables the positioning of the chain and facilitates the calibration of the zero point position after positioning. The two edges of the positioning strip near the chain are set as arc structures, which is more conducive to guiding and positioning the chain.
[0031] When the chain conveyor mechanism 201 is in use, the zero point position is first determined by the detection sensor. A large number of horizontal inductors are evenly and lowly placed on the placement frame of the horizontal top side section of the chain. The winding machine is started. While taking away the horizontal inductors at the end of the chain conveyor mechanism 201, horizontal inductors are placed on the placement frame. This achieves uniform and stable feeding of horizontal inductors. The distance between two adjacent placement frames and the running speed meet the process interval requirements of the set cycle time for subsequent winding, welding and other processes.
[0032] In Embodiment 1 of this application, the material loading and unloading mechanism 202 includes a lifting mechanism 2021, a clamping mechanism 2022, a lifting mechanism 2023, a horizontal moving mechanism 2024, and a pushing mechanism 2025. A lifting mechanism 2021 is installed at the end of the chain conveyor mechanism 201 to lift the horizontal inductor 40 placed and conveyed on the chain conveyor mechanism 201 away from the placement rack 2012 on the chain conveyor mechanism 201. A clamping mechanism 2022 is installed at one end of the cantilever 2026 and located above the lifting mechanism 2021. After the lifting mechanism 2023 lowers it, it is used to clamp the lifted horizontal inductor 40. The clamping mechanism 2022 adopts a pneumatic finger cylinder, which includes a cylinder body and two parallel relative moving fingers 20221. The clamping surfaces of the two fingers 20221 are respectively provided with two clamping blocks 20222. The two clamping blocks 20222 are horizontally provided with semi-circular arc grooves 20223 facing each other. When the two arc grooves 20223 are closed, they form a clamping hole for clamping the iron core shaft of the horizontal inductor 40. The arc groove 20223 is provided with an elastic protective layer for clamping and protecting the iron core shaft. The bent push rod 20251 of the push mechanism 2025 can move through the two clamping blocks 20222. The lifting mechanism 2023 is installed at the moving execution end of the horizontal moving mechanism 2024. The other end of the cantilever 2026 is fixedly connected to the end of the lifting mechanism 2023. After the lifting mechanism 2023 lifts the clamped horizontal inductor 40, the iron core shaft of the horizontal inductor 40 can face the clamping part of the horizontal inductor mounting fixture 30. The horizontal moving mechanism 2024 is installed on the worktable 10 for moving the cantilever 2026 toward the side of the horizontal inductor mounting fixture 30. The push mechanism 2025 is installed on the cantilever 2026 for pushing the iron core shaft of the horizontal inductor 40 to the clamping part of the horizontal inductor mounting fixture 30 for clamping and fixing. The lifting mechanism 2023 uses a lifting slide cylinder, and the horizontal movement mechanism 2024 uses a linear cylinder. The slide of the lifting slide cylinder is fixedly connected to one end of the cantilever, and the cylinder seat of the lifting slide cylinder is fixedly connected to the slide of the linear cylinder via an L-shaped back plate. The cylinder seat of the linear cylinder is fixedly connected to the worktable. The linear cylinder controls the horizontal linear movement of the cantilever, and the lifting slide cylinder controls the lifting of the cantilever.
[0033] All the slide cylinders used in this application are dual-axis precision slide cylinders, which have good directional movement.
[0034] In use, the lifting mechanism raises the horizontal inductor to a set height away from the placement rack. Then, the lifting mechanism lowers the open clamping mechanism to the position of the iron core shaft of the horizontal inductor and clamps and fixes it. After clamping and fixing the iron core shaft, the lifting mechanism raises the horizontal inductor to a position directly opposite the clamping part of the horizontal inductor mounting fixture 30. The horizontal moving mechanism 2024 moves the horizontal inductor toward the clamping part to the first set position (it does not reach the final position, but the clamping part is released, and the horizontal inductor will not fall off under the support of the guide mechanism and the cantilever of the clamping part). The clamping part of the clamping mechanism is released, and the pushing mechanism continues to push the horizontal inductor forward (at this time, the locking tongue of the clamping part of the horizontal inductor mounting fixture is not closed). When the second set position is reached, the locking tongue is released to press the iron core shaft of the horizontal inductor fed into the horizontal inductor mounting fixture, completing one loading and installation of a horizontal inductor.
[0035] To more accurately align the core shaft of the horizontal inductor 40 with the clamping part of the horizontal inductor mounting fixture 30, the material handling and loading mechanism 202 further includes a guide mechanism 2027. The guide mechanism 2027 is positioned between the horizontal inductor mounting fixture 40 and the pushing mechanism 2025. The guide mechanism 2027 has a guide cone hole 20271, which faces the clamping part of the horizontal inductor mounting fixture 40. Through the guide cone hole of this guide mechanism, the core shaft of the horizontal inductor is pushed towards the horizontal inductor mounting fixture. During the feeding process, the iron core shaft of the horizontal inductor can be initially guided and positioned, which is more conducive to its accurate entry into the mounting hole of the clamping part of the horizontal inductor mounting fixture. This avoids misalignment that would prevent the iron core shaft from entering the mounting hole. Specifically, the guiding mechanism 2027 includes a guide block 20272, a pneumatic finger cylinder 20273, and a guide lifting cylinder 20274. Two guide blocks 20272 are used, symmetrically fixedly connected to the two fingers 202731 of the pneumatic finger cylinder 20273. Two guide blocks 20272 have two semi-conical holes symmetrically arranged on their opposite faces. After the two guide blocks 20272 are closed, the two semi-conical holes form a complete guide cone hole 20271. The cylinder body of the pneumatic finger cylinder 20273 is fixedly connected to the top of the sliding table of the guide slide cylinder 20274 through an L-shaped fixed mounting seat 20276. The cylinder seat of the guide slide cylinder 20274 is fixedly connected to the worktable 10 through an inverted T-shaped fixed mounting seat 20275. (The vertical plate of 20275 is attached to the side of the cylinder seat). During use, the guide slide is controlled to raise the second pneumatic finger cylinder to ensure that the guide cone hole is aligned with the mounting hole (not locked) of the clamping part of the horizontal inductor mounting fixture 40. The second pneumatic finger cylinder is then controlled to close the guide cone hole. After the iron core shaft of the horizontal inductor is pushed through the guide cone hole and enters the mounting hole a certain distance, the guide cone hole is opened, the second pneumatic finger cylinder is lowered, and the pushing mechanism is controlled to continue to push the horizontal inductor into the clamping part of the horizontal inductor mounting fixture 40 for clamping and fixing.
[0036] The horizontal inductor is lifted to a set position (away from the chain conveyor) by a lifting mechanism, which facilitates the clamping mechanism to descend and grab it. After grabbing, it is pre-feeded forward into the clamping part of the horizontal inductor mounting fixture. The clamping mechanism is released, and the horizontal inductor is pushed into the last clamping part by a pushing mechanism for clamping and fixing. This material loading mechanism can achieve precise grabbing and docking of the horizontal inductor. It features independent linear control, which reduces the control difficulty, greatly improves the loading accuracy, and has high loading stability.
[0037] Specifically, in Embodiment 1 of this application, the lifting mechanism 2021 includes a U-shaped correction lifting frame 20211 and a lifting slide cylinder 20212; The U-shaped correction lifting frame 20211 has two side panels 202111 and a lifting base 202112 on its upper part. The side panels 202111 are located on both sides of the chain conveyor mechanism 201 at horizontal. The top of the side panels 202111 is provided with two symmetrical V-shaped grooves 202113. The two V-shaped grooves 202113 can support and correct the iron core shaft of the horizontal inductor 40. The correction is achieved by the self-positioning of the V-shaped grooves. The cylinder seat of the lifting slide cylinder 20212 is vertically mounted on the worktable 10 through the fixed mounting seat 3 20213. The slide of the lifting slide cylinder 20212 is fixedly connected to the lifting base 202112. The lifting slide cylinder 20212 lifts the horizontal inductor 40 away from the placement frame of the chain conveyor mechanism 201 through the U-shaped correction lifting frame 20211. The lifting height can meet the clamping height requirements of the clamping mechanism.
[0038] This lifting mechanism can quickly lift the horizontal inductor placed on the placement rack of the chain conveyor to a set height. The V-shaped groove has a self-positioning function, which can realize placement correction and placement, facilitate precise docking with the guide mechanism and make it easier for the clamping mechanism to hold, effectively avoiding interference between the clamping mechanism and the placement rack during the clamping process.
[0039] To facilitate height adjustment, the lifting base 202112 is equipped with two countersunk vertical slots 202114. Adjusting screws 202115 are used to pass through the vertical slots 202114 to fix the lifting base 202112 to the slide side plate of the lifting slide cylinder 20212. Through the vertical slots and adjusting screws, the height of the U-shaped correction lifting frame 20211 can be quickly adjusted, making the adjustment convenient and fast.
[0040] In order to ensure that the horizontal inductors are evenly centered on the placement rack, the material loading mechanism 202 also includes a centering mechanism 2028, which includes a centering baffle 20281 and a centering pusher 20282. The center baffle 20281 is fixedly connected to the chain conveyor mechanism 201 and is located away from the horizontal moving mechanism 2024, so that it can face the iron core shaft of the horizontal inductor 40 placed on the placement frame 2012 of the chain conveyor mechanism 201. The centering push plate 20282 is fixedly connected to the cantilever 2026 and faces the centering baffle 20281. When the horizontal moving mechanism 2024 drives the cantilever 2026 to move horizontally, it drives the centering push plate 20282 to push the horizontal inductor 40 placed on the placement rack 2012 toward the centering baffle 20281 for centering.
[0041] In use, this centering mechanism moves horizontally along with the horizontal moving mechanism, pushing the non-centered horizontal inductor towards the centering baffle for rapid centering. This achieves centering of the horizontal inductor placed on the rack before clamping it, improving the consistency of the core shaft position during each clamping of the horizontal inductor. This ensures that the initial depth of the horizontal inductor entering the clamping part is consistent, preventing it from falling due to insufficient insertion. Furthermore, the horizontal moving mechanism simultaneously achieves centering linkage while clamping and pushing the core shaft of the horizontal inductor into the guide cone hole, reducing the need for independent power mechanisms, lowering costs, and reducing the interference problem caused by excessive equipment installation.
[0042] To achieve wear resistance of the centering plate 20281, the centering plate 20281 includes a bent connecting steel plate 202811 and a centering copper plate 202812. One end of the bent connecting steel plate 202811 is fixedly connected to the chain frame 20111 of the chain conveyor mechanism 201, and the other end is bent away from the chain frame 20111. The centering copper plate 202812 is fixedly connected to the other end of the bent connecting steel plate 202811. Through this structure, on the one hand, centering and wear resistance are achieved, avoiding damage caused by long-term impact; on the other hand, the bent connecting steel plate can also provide stable support.
[0043] The centering push plate 20282 is bent after being twisted 90 degrees in the middle. One end plate is fixedly connected to the bottom plate of the middle support 201111. After the other end is twisted and bent, the plate surface can be directly aligned with the centering baffle 20281. The centering push plate 20282 is also made of copper sheet.
[0044] Specifically, in this embodiment 1, the pushing mechanism 2025 includes a bending pushing rod 20251, a pushing sliding plate 20252, a pushing slider guide rail pair 20253, and a pushing cylinder 20254; The bending push rod 20251 has a downward-facing fork 20255 at its front end. After bending the bending push rod 20251 multiple times, the fork 20255 is positioned in front of the clamping part of the clamping mechanism 2022. That is, a section of the bending push rod 20251 near the fork 20255 can move through the gap between the two fingers of the clamping mechanism 2022 when they are closed. The fork 20255 can be inserted into the iron core shaft of the horizontal inductor 40 and is located on the side away from the horizontal inductor mounting fixture 30. When the fork 20255 moves toward the side of the horizontal inductor mounting fixture 30, it can abut against the side of the magnetic core and push the horizontal inductor 40 into the last section of the clamping part of the horizontal inductor mounting fixture 30 for positioning and clamping. The push sliding plate 20252 is fixedly connected to the push rod fixing seat 20256. The push rod fixing seat 20256 is arranged on the side close to the clamping mechanism 2022. The rear end of the bent push rod 20251 is fixedly connected to the front end face of the push rod fixing seat 20256. The push slider guide rail pair 20253 has a guide rail and a slider. The guide rail is fixedly connected to the side of the cantilever 2026, and the slider is fixedly connected to the push sliding plate 20252. The push cylinder 20254 has a cylinder seat and a cylinder rod. The cylinder seat is fixedly connected to the cantilever 2026 and located on the rear side of the guide rail. The cylinder rod is fixedly connected to the short plate of the L-shaped cylinder connecting plate 20257. The long plate of the L-shaped cylinder connecting plate 20257 is fixedly connected to the push sliding plate 20252.
[0045] After the clamping mechanism pushes the horizontal inductor into the guide cone hole and the clamping part of the horizontal inductor mounting fixture (not yet fixed), the clamping mechanism is released (two fingers are released) and the guide cone hole of the guide mechanism is released and lowered (to avoid interference with the forward push of the shift fork). The horizontal inductor is in a suspended state. The cylinder rod of the control push cylinder is pushed out, which drives the sliding plate to move horizontally and linearly along the push slider guide rail pair 20253, thereby driving the bending push rod 20251 to move. The bending push rod 20251 moves between the two fingers and moves forward, driving the shift fork to move forward. When the clamping mechanism clamps the iron core shaft of the horizontal inductor, the shift fork is stuck on the iron core shaft. The shift fork moves forward and pushes the horizontal inductor to the final positioning position after it comes into contact with the magnetic core side of the horizontal inductor. The clamping part of the horizontal inductor mounting fixture is used to lock the iron core shaft of the horizontal inductor. The shift fork is retracted and the push mechanism and clamping mechanism are raised.
[0046] The pushing mechanism consists of a bending push rod, a pushing slide plate, a pushing slider guide rail pair, and a pushing cylinder. A fork is set at the pushing point of the bending push rod. The fork is movably locked on the iron core shaft, realizing the rapid pushing of the second segment of the horizontal inductor. The pushing is stable and has a clearance space. The iron core shaft will not be subjected to radial force during the insertion of the clamping hole, and there will be no jamming that could damage the iron core shaft. A secondary close-range pushing is arranged on the cantilever to shorten the horizontal movement stroke of the horizontal moving mechanism.
[0047] The bending push rod 20251 includes a first vertical rod 202511, a first horizontal rod 202512, a first longitudinal rod 202513, a second vertical rod 202514, a second longitudinal rod 202515, and a third vertical rod 202516. The upper end of the first vertical rod 202511 is fixedly connected to the front end of the push rod fixing seat 20256. The upper end of the first vertical rod 202511 is fixedly connected to the right end of the first horizontal rod 202512. The first horizontal rod 202512 is located below the cantilever 2026. The left end of the first horizontal rod 202512 is fixedly connected to the rear end of the first longitudinal rod 202513. The front end of the first longitudinal rod 202513 is fixedly connected to the upper end of the second vertical rod 202514, and the lower end of the second vertical rod 202514 is fixedly connected to the rear end of the second longitudinal rod 202515. The second longitudinal rod 202515 moves horizontally through the gap between the two fingers of 2022 when they are closed. The front end of the second longitudinal rod 202515 is fixedly connected to the upper end of the third vertical rod 202516, and the upper and lower ends of the third vertical rod 202516 are fixedly connected to the upper end of the shift fork 20255. The bending push rod 20251 of this structure can effectively avoid interference and can push the horizontal inductor in a centered manner.
[0048] To achieve limit protection, a limit stop 20260 is provided on the side of the guide rail facing the horizontal inductor mounting fixture 30. The limit stop 20260 is fixedly connected to the end of the protection position adjusting screw 20258. The protection position adjusting screw 20258 is screwed onto the protection position mounting base 20259. The protection position mounting base 20259 is fixedly connected to the cantilever, and the limit stop 20260 faces the middle of the left side of the slider. An elastic layer is provided on the right end face of the limit stop 20260. Through this structure, the leftward movement of the slider can be limited to avoid damage to the horizontal inductor or equipment due to excessive movement. It can also adjust the protection position for horizontal inductors of different lengths.
[0049] The horizontal inductor mounting fixture 30 includes a fixed fixture plate 301, a movable fixture plate 302, a compression spring 303, and a rotary pneumatic finger cylinder 304. The fixed fixture plate 301 is fixedly connected to the output rotary table 501 of the rotary table 50. The fixed fixture plate 301 has a pointed tip 305 facing the material handling and loading mechanism 202. The pointed tip 305 has a clamping hole 306, which is parallel to the first side surface 3051 of the pointed tip 305. The front end of the pointed tip 305 has a front end face perpendicular to the first side surface 3051. The clamping hole 306 is located at the front end of the pointed tip 305. On the front end face, the first side surface 3051 is provided with a strip-shaped notch 307 that connects to the clamping hole 306. The movable clamp plate 302 is rotatably connected to the output rotating frustum 501 via a rotating shaft 308 and is located on one side of the first side surface 3051. The rotating shaft 308 is located to the side of the rear end of the first side surface 3051, allowing the movable clamp plate 302 to rotate 15-45° around the rotating shaft. A protruding pressure strip 309 is provided on the movable clamp plate 302 facing the first side surface 3051. After the front end of the movable clamp plate 302 rotates towards the first side surface 3051, the protruding pressure strip 309 can move. The strip-shaped notch 307 is embedded to press the iron core shaft of the horizontal inductor 40. The tail end of the movable clamping plate 302 extends a certain distance from the fixed clamping plate 301 and is fixedly connected to one end of the compression spring 303 facing the fixed clamping plate 301. The other end of the compression spring 303 is fixedly connected to the output rotating frustum 501 through the spring seat 312. The compression spring 303 can keep the protruding pressure strip 309 at the front end of the movable clamping plate 302 pressing the iron core shaft of the horizontal inductor 40. The cylinder seat of the rotary pneumatic finger cylinder 304 is fixedly connected through the connecting seat 313. The rotary pneumatic finger cylinder 304, attached to the fixed platform 60, is equipped with a swinging finger 310. The swinging finger 310 is equipped with a rubber sleeve 311. After the swinging finger 310 rotates inward to close, the rubber sleeve 311 can push the movable clamping plate 302 to rotate around the rotating axis, opening the convex pressure bar 309. The structure of this horizontal inductor mounting clamp relies on the compression spring to provide clamping force, which can ensure that the horizontal inductor is clamped stably and reliably, and the positioning is accurate. When opening the loading, the finger of the rotary pneumatic finger cylinder 304 swings to open the clamping convex pressure bar 309, and the opening control is easy.
