Description

TECHNICAL FIELD

[0001] The application relates to the technical field of magnetic ring inductor production equipment, in particular to a magnetic ring inductor positioning plate penetrating device. BACKGROUND

[0002] The manufacturing of intelligent reactors, transformers, rectifiers and inductors is a core link for building efficient, flexible and safe power grids, among which the magnetic ring inductor is widely used in the smart grid industry due to its high-frequency filtering performance.

[0003] Two windings are wound on the magnetic ring inductor, and each winding has two pins. During the production of the magnetic ring inductor, a plastic partition plate is used for plate penetrating operation to simultaneously solve the problems of safety distance, mechanical fixation and heat dissipation. The finished magnetic ring inductor needs to ensure winding insulation to avoid turn-to-turn short circuit and inductor damage. The existing plate penetrating operation is mostly handheld operation, and the worker needs to manually penetrate the four pins of the magnetic ring inductor through the positioning plate and insert them into the plastic partition plate, and then shape them. This operation method is not only inefficient, but also causes the finished product style to be inconsistent due to human factors, ultimately affecting the pass rate of the finished magnetic ring inductor. In view of the above problems, there are good solutions in the prior art, such as the magnetic ring inductor plate penetrating and shaping machine with the publication number CN113327766B, which improves the assembly efficiency and precision of the product and improves the pass rate of the finished magnetic ring inductor through the cooperation between the magnetic ring inductor positioning plate penetrating device and the displacement shaping device. However, there are still the following defects: since the hole diameter of the plastic partition plate is fixed, and the positions of the pins on different magnetic ring inductors are deviated, there is a situation that the pins are rubbed with the hole wall when the pins are inserted into the hole of the plastic partition plate, which causes the insulation paint to be damaged, affects the winding insulation performance, and also affects the pass rate of the finished magnetic ring inductor.

[0004] Therefore, in order to solve the above problems, a magnetic ring inductor positioning plate penetrating device is proposed. SUMMARY

[0005] The purpose of the present application is to provide a magnetic ring inductor positioning plate penetrating device, which solves the problem that the insulation paint is damaged due to friction between the pins and the hole wall when the pins are inserted into the hole of the plastic partition plate, thereby affecting the pass rate of the finished magnetic ring inductor. Through the positioning hole opened on the positioning plate, the four pins of the magnetic ring inductor can be smoothly inserted into the hole of the plastic partition plate, and the insulation paint on the surface of the pin will not be scratched during the insertion process; at the same time, through the setting of the splicing assembly, the pressing assembly and the pressing plate, the stable contact between the magnetic ring inductor body and the plastic partition plate can be realized before the four pins of the magnetic ring inductor are shaped, avoiding the shaking of the plastic partition plate in the finished product, and realizing the double guarantee of the pass rate of the finished magnetic ring inductor.

[0006] To achieve the above purpose, the present application provides the following technical solutions:

[0007] A magnetic ring inductive positioning and plate-passing device includes a worktable, a support plate, a motor, and a positioning plate. The positioning plate is composed of two sub-plates spliced ​​together. The support plate is fixedly mounted on the worktable, and the motor is fixedly mounted on the support plate. The device also includes a splicing assembly, a pressing assembly, and a pressure plate. The splicing assembly is mounted on the worktable and connected to the motor and the two sub-plates. When the motor is powered on and started, the splicing assembly drives the two sub-plates to fit together or separate. The pressing assembly is mounted on the worktable and connected to the splicing assembly. The pressure plate is connected to the pressing assembly. When the two sub-plates fit together or separate, the pressing assembly drives the pressure plate to rise or fall.

[0008] Preferably, the surface of the sub-plate is provided with positioning holes, the positioning holes including an upper hole and a lower hole that are connected and coaxially arranged. The diameter of the upper hole decreases linearly from top to bottom, the diameter of the lower hole is equal to the lower end diameter of the upper hole, and the connection between the upper hole and the lower hole is rounded and chamfered. The inner wall of the upper hole has a plurality of guide grooves arranged in a circular array, and the center line of the guide grooves intersects the axis of the upper hole and the lower hole.

[0009] It is known that in order to ensure that the four pins of the magnetic ring inductor can be smoothly inserted into the openings on the plastic partition, positioning holes need to be made on the surface of the positioning plate composed of two sub-plates. However, the diameter of the conventional positioning hole is only slightly larger than the diameter of the pin. When inserting the four pins into the corresponding positioning holes, the operator needs to manually align the four pins with the corresponding positioning holes. This affects work efficiency and may also cause the insulating varnish on the pins to be damaged due to friction between the end of the positioning hole and the pin surface, thus affecting the insulation performance of the winding and reducing the pass rate of the finished magnetic ring inductor. Therefore, this solution is adopted. By setting upper and lower holes, the upper diameter of the positioning hole can be enlarged, making it easier for workers to insert the four pins of the magnetic ring inductor into the corresponding positioning holes. The change in the diameter of the upper hole and the guide groove opened on the inner wall of the upper hole can guide the movement path of the pins. Even if the pin deviates from the axis of the positioning hole, the pin can still be smoothly inserted into the corresponding lower hole. Furthermore, the rounded chamfer at the connection between the upper and lower holes prevents the insulating paint on the pin surface from being scratched, improving work efficiency and ensuring the pass rate of the finished magnetic ring inductor.

[0010] Preferably, the splicing assembly comprises a bidirectional screw rod, a sliding block, a ring-shaped frame, a connecting frame, a circular table and a guide rod, the bidirectional screw rod is rotationally arranged on a support plate and fixedly connected with an output end of a motor, the sliding block is arranged on the bidirectional screw rod and threadedly connected with the bidirectional screw rod, the ring-shaped frame is fixedly arranged on the sliding block and slidably attached to a surface of a workbench, the connecting frame is arranged on the ring-shaped frame and connected with a corresponding sub-plate, the circular table is fixedly arranged on the bidirectional screw rod, and the diameter linearly decreases from an end position to a middle position of the bidirectional screw rod, and the guide rod is fixedly arranged on the sub-plate and slidably connected with a surface of the circular table.

[0011] It can be known that after the four pins of the magnetic ring inductor are shaped, the two sub-plates need to be separated to take out the finished product of the magnetic ring inductor. Considering that the sub-plates are located between the magnetic ring inductor body and the plastic partition plate during shaping, there is a movable gap between the plastic partition plate and the magnetic ring inductor body of the finished product, thereby causing the safety distance to be small and the high-voltage breakdown risk to exist. Therefore, the scheme is adopted. By arranging the bidirectional screw rod, the sliding block, the circular table and the guide rod, the two sub-plates can be driven to move away from each other by the rotation of the bidirectional screw rod before shaping, so that the magnetic ring inductor body can fall under the action of its own gravity and finally contact the plastic partition plate, thereby avoiding the shaking of the plastic partition plate of the finished product magnetic ring inductor after shaping, and effectively ensuring the qualified rate of the finished product magnetic ring inductor.

[0012] Preferably, the pressing assembly comprises a fixed rod, a placement table and a U-shaped rod, the fixed rod is arranged on the workbench, and the placement table and the pressing plate are arranged on the fixed rod, wherein the placement table is fixedly sleeved with the fixed rod, the pressing plate is movably sleeved with the fixed rod, a strip-shaped opening is arranged on the surface of the pressing plate, a spiral guide groove is arranged on the surface of the circular table along the axial direction, one end of the U-shaped rod is provided with an elastic element and connected with the pressing plate through the elastic element and the strip-shaped opening, and the other end is arranged in the spiral guide groove, the number of spiral turns of the spiral guide groove is the same as that of the thread on one end of the bidirectional screw rod, and the spiral direction of the spiral guide groove is opposite to the thread direction of one end of the bidirectional screw rod; the thread heights of the two ends of the bidirectional screw rod are equal, and the radius difference of the two ends of the circular table is greater than the thread height of the two ends of the bidirectional screw rod.

[0013] It can be known that the aperture of the opening on the plastic partition is only slightly larger than the diameter of the pin, and the pin is not strictly kept in a vertical state after being inserted into the opening on the plastic partition, that is, there is friction between the pin and the inner wall of the corresponding opening, although the magnetic ring inductor body can be contacted with the surface of the plastic partition by manually pressing downward, but it cannot be guaranteed that the magnetic ring inductor moves vertically downward when pressing downward, so that the pin of the magnetic ring inductor may be bent, thereby affecting the qualified rate of the magnetic ring inductor product, and therefore the scheme is adopted. The pressure plate, the U-shaped rod and the spiral guide groove opened on the surface of the circular table are arranged, so that in the process of the bidirectional screw rod rotating and driving the two auxiliary plates to move upward and separate, the pressure plate is driven to move downward and press the magnetic ring inductor body by the sliding connection of the U-shaped rod and the spiral guide groove, so that the magnetic ring inductor body can move downward along the vertical direction, which can simplify the working steps while avoiding the pin bending, thereby ensuring the qualified rate of the magnetic ring inductor product and improving the work efficiency.

[0014] Preferably, the connecting frame comprises an L-shaped plate, an L-shaped rod, a plug plate and a mounting plate, one end of the L-shaped plate is movably sleeved with the annular frame, the other end is detachably connected with the corresponding auxiliary plate, one end of the L-shaped rod is connected with the L-shaped plate, the other end is connected with the plug plate, the mounting plate is arranged on the fixed rod and has a plug hole opened in the inside, the mounting plate is movably sleeved with the fixed rod, and a shaping device for shaping the four pins of the magnetic ring inductor is mounted in the mounting plate. The shaping device is an existing device and can be directly installed and used, so it is not described in detail here. The plug plate is provided with a plug rod, and the plug rod is inserted into the plug hole of the mounting plate.

[0015] By using the movable insertion of the plug rod and the mounting plate and the movable sleeve of the mounting plate and the fixed rod, the mounting plate is driven to move upward synchronously in the process of the two auxiliary plates moving upward and separating, so that the shaping device mounted on the mounting plate can be close to the magnetic ring inductor body, so as to facilitate the shaping treatment of the four pins of the magnetic ring inductor, and the shaping device will not block the placement of the plastic partition on the placement table and the insertion of the four pins of the magnetic ring inductor to be shaped into the openings on the plastic partition, and it is not necessary to drive the shaping device to move upward by the driving member before shaping. In addition, the work efficiency is further improved while ensuring the qualified rate of the magnetic ring inductor product.

[0016] Preferably, the elastic member comprises a stop block one, a spring and a stop block two sleeved on the U-shaped rod, the two stop block ones are arranged, the lower stop block one is in sliding fit with the lower surface of the pressure plate, the stop block two is arranged between the two stop block ones and is in sliding fit with the upper surface of the pressure plate, and the spring is arranged between the upper stop block one and the stop block two.

[0017] By adopting the above scheme, after the pressure plate moves down to contact the magnetic ring inductor body, the extensibility of the spring allows the U-shaped rod to continue moving down under the action of the spiral guide groove, so that the pressure plate can achieve flexible compression of the magnetic ring inductor body. This avoids deformation of the coil on the magnetic ring inductor body while ensuring the compression effect on the magnetic ring inductor body, so that the magnetic ring inductor body can make stable contact with the plastic partition, further ensuring the qualification rate of the finished magnetic ring inductor.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By using two sub-boards and splicing components, and utilizing the connected upper and lower holes on the sub-boards, when the four pins of the magnetic ring inductor are inserted through the board, the upper diameter of the upper hole can expand the insertion range of the pins and reduce the obstruction range of the pins by the sub-board. This allows the pins to be smoothly inserted into the lower hole under the action of the upper hole and finally inserted into the opening on the plastic partition. During the insertion process, the guide groove on the inner wall of the upper hole can guide the pins and prevent the pins from deviating from the central axis of the upper and lower holes. At the same time, the rounded chamfer at the connection between the upper and lower holes can protect the insulating varnish on the pin surface and prevent the insulating varnish from being scratched, effectively ensuring the pass rate of the finished magnetic ring inductor.

[0020] 2. By using the splicing components, the two sub-plates can be separated during the forward rotation of the bidirectional lead screw. This allows the four pins of the magnetic ring inductor to maintain contact with the plastic partition during the shaping process. Furthermore, during the separation of the two sub-plates, the guide rods on the two sub-plates can slide upwards through the corresponding frustum surfaces, thereby automatically moving the mounting plate with the shaping device upwards. This ensures the high yield of the finished magnetic ring inductor while also improving work efficiency.

[0021] 3. Through the splicing and pressing components, as the bidirectional lead screw rotates forward and drives the two auxiliary plates away from each other, the end of the U-shaped rod will move closer to the middle of the bidirectional lead screw under the action of the spiral guide groove on the surface of the frustum. At the same time, the change in the diameter of the frustum will drive the pressure plate to move downward, so that the pressure plate can squeeze the magnetic ring inductor body. That is, before the four pins of the magnetic ring inductor are shaped, the magnetic ring inductor body and the plastic partition maintain a stable contact state, which further ensures the qualification rate of the finished magnetic ring inductor.

The connecting part of the upper hole 4111 and the lower hole 4112 is provided with a circular arc chamfer.

The center line of the guide groove 4113 intersects with the axis of the upper hole 4111 and the lower hole 4112. The groove depth of the guide groove 4113 is decreased from top to bottom, so as to adapt to the slight deflection of the pin and provide stable sliding guidance.

[0033] Under the above setting condition, after the four pins of the magnetic ring inductance are inserted into the corresponding upper holes 4111 and then pressed downward, the four pins gradually approach the axis position of the lower holes 4112 through the change of the hole diameters of the corresponding upper holes 4111. When the pins are slightly deflected, the bottom of the pin is forced to approach the axis of the lower hole 4112 under the action of the corresponding guide groove 4113, so that the pin can be inserted into the corresponding lower hole 4112. At the same time, since the connecting part of the upper hole 4111 and the lower hole 4112 is provided with a circular arc chamfer, the insulating paint on the pin will not be scratched, thereby effectively ensuring the qualified rate of the magnetic ring inductance product.

[0036] As an embodiment of the present application, reference is made to Figure 1 , Figure 5 , Figure 6 and Figure 7The lower pressing assembly 6 is arranged on the workbench 1 and connected with the splicing assembly 5, the pressing plate 7 is connected with the lower pressing assembly 6, and the two sub-plates 41 are adhered or separated, and the lower pressing assembly 6 drives the pressing plate 7 to rise or fall; the lower pressing assembly 6 comprises a fixed rod 61, a placing table 62 and a U-shaped rod 63, the fixed rod 61 is arranged on the workbench 1, the placing table 62 and the pressing plate 7 are arranged on the fixed rod 61, wherein the placing table 62 is fixedly sleeved with the fixed rod 61, the pressing plate 7 is movably sleeved with the fixed rod 61, a strip-shaped hole 71 is formed in the surface of the pressing plate 7, a spiral guide groove 551 is formed in the surface of the circular table 55 along the axial direction, one end of the U-shaped rod 63 is provided with an elastic element 64, and the other end is arranged in the spiral guide groove 551 (in order to avoid separation of the end of the U-shaped rod 63 from the spiral guide groove 551, a corresponding clamping groove can be formed in the rod wall of the U-shaped rod 63, so that the slot opening of the spiral guide groove 551 is slidably clamped in the inside of the clamping groove, and the U-shaped rod 63 and the spiral guide groove 551 are stably slidably connected under the action of the clamping groove), the number of spiral turns of the spiral guide groove 551 is the same as the number of threads at one end of the bidirectional screw rod 51, and the spiral direction of the spiral guide groove 551 is opposite to the thread direction at one end of the bidirectional screw rod 51; the thread heights of the two ends of the bidirectional screw rod 51 are equal, and the radius difference between the two ends of the circular table 55 is greater than the thread height of the two ends of the bidirectional screw rod 51; the elastic element 64 comprises a first stop block 641, a spring 642 and a second stop block 643 which are sleeved on the U-shaped rod 63, the two first stop blocks 641 are arranged below and slidably adhere to the lower surface of the pressing plate 7, the second stop block 643 is arranged between the two first stop blocks 641 and slidably adheres to the upper surface of the pressing plate 7, and the spring 642 is arranged between the upper first stop block 641 and the second stop block 643.

[0038] Working principle:

[0039] In the initial state, the motor 3 is not working, and the two auxiliary plates 41 are attached to each other. First, place the plastic partition on the placement table 62 (the placement of the plastic partition has been automated, and a partition material bin can be set on one side of the device. A pneumatic push rod is provided at the bottom of the material bin. When the device starts working, the pneumatic push rod pushes out and pushes the bottommost plastic partition along the guide rail to the center position of the placement table 62). Then, insert the four pins of the magnetic ring inductor into the corresponding upper holes 4111 and press downward. The four pins are smoothly inserted into the corresponding holes in the plastic partition under the action of the hole walls of the corresponding upper holes 4111 and the corresponding guide grooves 4113.

[0040] The motor 3 is started, and the output end of the motor 3 drives the bidirectional screw rod 51 to rotate. When the bidirectional screw rod 51 rotates forward, on the one hand, the two sliding blocks 52 on the bidirectional screw rod 51 can drive the corresponding annular frames 53 to move away from each other, and the annular frames 53 move away from each other, and the L-shaped plate 541 drives the corresponding sub-plates 41 to move away from each other. Since the L-shaped plate 541 is movably sleeved with the annular frame 53, and the bidirectional screw rod 51 is provided with a circular truncated cone 55 with a diameter decreasing linearly from the end of the bidirectional screw rod 51 to the middle part, the guide rod 56 provided on the sub-plate 41 moves upward along the surface of the circular truncated cone 55, that is, the L-shaped plate 541 moves upward; and in the process of upward movement of the L-shaped plate 541, the L-shaped rod 542 provided on the L-shaped plate 541 drives the plug-in plate 543 connected thereto to move upward. Since the plug-in plate 543 is provided with a plug-in rod 5431, and the mounting plate 544 is movably sleeved with the plug-in rod 5431, the mounting plate 544 can be driven to move upward synchronously, that is, the shaping device for shaping the four pins of the magnetic ring inductor mounted on the mounting plate 544 is automatically moved upward and close to the magnetic ring inductor, so as to shape the four pins of the magnetic ring inductor; on the other hand, the circular truncated cone 55 coaxially sleeved with the bidirectional screw rod 51 also rotates with the bidirectional screw rod 51. Since the circular truncated cone 55 is provided with a spiral guide groove 551 with a spiral direction opposite to that of the corresponding thread on the bidirectional screw rod 51, when the circular truncated cone 55 rotates forward synchronously with the bidirectional screw rod 51, one end of the U-shaped rod 63 is pressed by the spiral guide groove 551, so that the U-shaped rod 63 moves to the middle part of the bidirectional screw rod 51, and the end of the U-shaped rod 63 moves downward along the slot of the spiral guide groove 551. When the U-shaped rod 63 moves downward, the stop block two 643 provided thereon moves downward synchronously, so that the pressing plate 7 cannot move downward due to the blocking of the magnetic ring inductor, that is, the magnetic ring inductor body is in contact with the plastic partition plate. At this time, with the continuous downward movement of the U-shaped rod 63, the stop block two 643 deforms the spring 642, and the pressing plate 7 flexibly clamps the magnetic ring inductor through the elastic force of the spring 642, so as to ensure the smoothness of the shaping process.

[0041] After the four pins of the magnetic ring inductor are shaped, the motor 3 is restarted, the output end of the motor 3 drives the bidirectional screw rod 51 to reverse, that is, the two sliding blocks 52 move close to each other, and the finished product is taken out after the pressing plate 7 is separated from the magnetic ring inductor, until the two sub-plates 41 are in contact, so as to perform the next plate penetrating and shaping operation.

[0042] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
