Description

Technical Field

[0001] This utility model relates to the field of inductor manufacturing and processing technology, specifically to a pin trimming device for inductor manufacturing. Background Technology

[0002] An inductor converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance; it only impedes changes in current. If no current is flowing through the inductor, it will attempt to impede the current flow when the circuit is closed; if current is flowing through the inductor, it will attempt to maintain a constant current when the circuit is open. Inductors are also called chokes, reactors, or dynamic reactors.

[0003] Patent document CN218214988U discloses a pin trimming device for inductor production. The device uses a fixed box to hold the inductor and covers it. The portion of the inductor pin that passes through the through-hole inside the fixed box is considered excessively long. This is trimmed using a first and second switch. This pin trimming device eliminates the need to measure pin length during trimming; simply placing the inductor inside the fixed box and closing the cover allows for pin trimming. This ensures effective trimming while providing greater convenience and significantly improving work efficiency.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] This inductor production pin trimming device uses a first and second switch in conjunction to mimic the cutting motion of scissors during the inductor pin trimming process, which can improve work efficiency. However, in actual applications, the first and second switches are affected by the fork-shaped cutting motion, making it difficult to trim the inductor pins at the same time, resulting in low trimming efficiency and a limited number of inductors that can be trimmed in a single operation. Utility Model Content

[0006] To overcome the shortcomings of existing inductor lead trimming devices in practical applications, such as the first and second blades being affected by the fork-type shearing method, making it difficult to trim the leads of the inductors used at the same time, resulting in low trimming efficiency and a limited number of inductors that can be trimmed at one time, this application provides an inductor lead trimming device. By setting multiple trimming structures on the top of the device's base plate, and since multiple trimming structures are assembled on the top of the same base plate, the inductors are positioned with the help of multiple support sleeves at the bottom of the multiple trimming structures. When the inductor passes through the interior of the trimming structure, the hinge seat and base plate can be controlled by an electric push rod to drive the multiple trimming structures to move. Multiple inductors are supported by multiple support sleeves and their leads are trimmed simultaneously, which greatly improves the trimming efficiency.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A lead trimming device for inductor production includes a trimming structure and a base plate, wherein the trimming structure is provided with multiple trimming structures.

[0009] The seat plate is assembled to one end of multiple trimmed structures;

[0010] The seat plate has an integrally formed hinge seat on the side away from the multiple trimming structures, and an electric push rod is hinged to the center of the side of the hinge seat away from the seat plate via a shaft.

[0011] The bottom of the multiple trimming structures is provided with the same device base plate, and the top of the device base plate is assembled with multiple support sleeves. An inductor is placed inside the side of the multiple support sleeves facing the base plate.

[0012] The inductor pins pass through the interior of the trimming structure, and the hinge base and base plate are controlled by an electric push rod to move multiple trimming structures, with multiple support sleeves supporting the trimming inductor pins.

[0013] In one possible implementation, a base is mounted on the top of one end of the device base plate, and the fixed end of the electric push rod is mounted and fixed to the side of the base near the base plate, so that the electric push rod remains in a horizontal state.

[0014] In one possible implementation, limit sleeves are provided on both sides of the movable end of the electric push rod, and both limit sleeves are sleeved on the outside of the shaft, so that the connection end between the electric push rod and the shaft is at the center.

[0015] In one possible implementation, the trimming structure includes a first trimming arm and a second trimming arm, both of which have multiple cuts arranged in a straight line inside. The first and second trimming arms are arranged side by side and remain symmetrical in vertical projection. The two pins of the inductor extend into the cuts on the first and second trimming arms, respectively.

[0016] In one possible implementation, the top of the seat plate is provided with multiple limiting grooves, and each of the multiple limiting grooves is provided with a column at the bottom inner wall. One end of the column is threadedly connected to a nut. One end of the first trimming arm and the second trimming arm are respectively placed inside the two limiting grooves in an adjacent state, so that the column passes through the inside of the first trimming arm or the second trimming arm, and the nut is supported at the top surface of the first trimming arm or the second trimming arm.

[0017] In one possible implementation, a pad is provided between the bottom surface of the first trimming arm and the bottom inner wall of the limiting groove. The pads at the bottom of the first trimming arm and the second trimming arm can be configured to have different heights. The pads are sleeved on the outside of the column and adapted to be connected inside the limiting groove.

[0018] In one possible implementation, multiple support sleeves are mounted between the bottoms of adjacent first and second trimming arms and are adapted to the height of the first and second trimming arms.

[0019] In one possible implementation, guide arms are integrally formed at both ends of the base plate, and a strip groove is formed on the bottom surface of the guide arm. Track bars are provided at the top of the two long sides of the device base plate, and the guide arms are slidably connected to the top of the track bars through the strip grooves.

[0020] The beneficial effects of this application are as follows:

[0021] First, in this solution, multiple trimming structures are set on the top of the device base plate. Since multiple trimming structures are assembled on the top of the same base plate, the inductors are positioned with the help of multiple support sleeves at the bottom of the multiple trimming structures. When the inductor passes through the interior of the trimming structure, the hinge seat and the base plate can be controlled by an electric push rod to drive the multiple trimming structures to move. Multiple inductors are supported by multiple support sleeves and their pins are trimmed at the same time, which greatly improves the trimming efficiency.

[0022] Secondly, in this solution, by opening multiple cutouts arranged in a row inside both the first and second trimming arms, and by adding a pad in the limiting groove at the base plate to control the height of the first and second trimming arms after assembly, the two pins on the inductor can be inserted into two cutouts of different heights respectively, thereby trimming pins of different lengths to meet actual usage requirements, which is simple and convenient.

Detailed Implementation

[0027] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0028] Example 1:

[0029] This embodiment describes the specific structure of a pin trimming device for inductor production, as detailed in the following reference. Figures 1-3 As shown, it includes multiple trimming structures 3 and a seat plate 6 assembled to one end of the multiple trimming structures 3. A hinge seat 2 is integrally formed on the side of the seat plate 6 away from the multiple trimming structures 3. An electric push rod 8 is hinged to the center of the side of the hinge seat 2 away from the seat plate 6 via a shaft.

[0030] The bottom of multiple trimming structures 3 is provided with the same device base plate 1. The top of one end of the device base plate 1 is assembled with a base 9. The top of the device base plate 1 is assembled with multiple support sleeves 10. Inductors 13 are placed inside the side of the multiple support sleeves 10 facing the base plate 6.

[0031] In this way, by assembling and fixing the fixed end of the electric push rod 8 to the side of the base 9 near the base plate 6, the electric push rod 8 is kept in a horizontal state. After the pin of the inductor 13 passes through the interior of the trimming structure 3, the electric push rod 8 can control the hinge base 2 and the base plate 6 to drive multiple trimming structures 3 to move, and multiple support sleeves 10 are used to support the pin of the trimming inductor 13.

[0032] Secondly, in order to enable multiple trimming structures 3 to move smoothly in the horizontal plane, such as Figure 2 As shown, guide arms 5 are integrally formed at both ends of the base plate 6. A strip groove 12 is provided on the bottom surface of the guide arm 5. Track bars 11 are provided at the top of the two long sides of the device base plate 1. When the base plate 6 is rotated around the connection point of the hinge seat 2 and one end of the electric push rod 8 and flipped down to the bottom (when flipped up, it mainly provides convenience for multiple inductors 13 to be placed on the inside of each support sleeve 10), the guide arm 5 is positioned by the cooperation of the track bar 11 and the strip groove 12. When multiple trimming structures 3 trim the pins of the inductors 13 in the horizontal plane, the guide arm 5 is slidably connected to the top of the track bar 11 through the strip groove 12. The trimming structure 3 can be mounted on the base plate 6, so that the track bar 11 and the guide arm 5 control the movement path of the trimming structure 3.

[0033] Furthermore, to prevent the connection end between the electric actuator 8 and the hinge seat 2 from shifting left or right outside the shaft, such as... Figure 1 As shown, limit sleeves 7 are provided on both sides of the movable end of the electric push rod 8. By fitting the two limit sleeves 7 onto the outside of the shaft, the connection end between the electric push rod 8 and the shaft can be centered, ensuring that after the electric push rod 8 is connected to the hinge seat 2, the multiple trimming structures 3 on the top of the seat plate 6 are in the correct position.

[0034] The above design sets multiple trimming structures 3 on the top of the device base plate 1. Since multiple trimming structures 3 are assembled on the top of the same base plate 6, when the control base plate 6 is rotated around one end of the electric push rod 8 to flip multiple trimming structures 3 to the top, multiple inductors 13 can be placed inside multiple support sleeves 10 one by one, and the pins of the inductors 13 can be supported by their top surface. When the base plate 6 is rotated around the connection point of the hinge seat 2 and one end of the electric push rod 8 to the bottom, the guide arm 5 can be positioned by the cooperation of the track bar 11 and the strip groove 12, thereby controlling multiple trimming structures 3 to be accurately located on the top of multiple inductors 13.

[0035] Meanwhile, with the help of multiple support sleeves 10 at the bottom of multiple trimming structures 3 to position the inductor 13, when the inductor 13 passes through the interior of the trimming structure 3, the hinge seat 2 and the seat plate 6 can be controlled by the electric push rod 8 to drive the multiple trimming structures 3 to move. Multiple inductors 13 are supported by multiple support sleeves 10 and their pins are trimmed at the same time, which greatly improves the trimming efficiency.

[0036] Example 2:

[0037] Based on Example 1, this example describes the specific structure of the pruning structure 3, such as... Figure 2 and Figure 3 As shown, the trimming structure 3 includes a first trimming arm 301 and a second trimming arm 302. Both the first trimming arm 301 and the second trimming arm 302 have multiple cuts 4 arranged in a straight line inside.

[0038] The top of the seat plate 6 is provided with multiple limiting grooves 17, and each of the multiple limiting grooves 17 is provided with a column 14 at the bottom inner wall, and one end of the column 14 is threadedly connected with a nut 16.

[0039] One end of the first trimming arm 301 and the second trimming arm 302 are respectively placed inside the two limiting grooves 17 in an adjacent state. After the column 14 passes through the inside of the first trimming arm 301 or the second trimming arm 302, the nut 16 can be supported at the top surface of the first trimming arm 301 or the second trimming arm 302, thereby fixing the first trimming arm 301 and the second trimming arm 302 to the seat plate 6.

[0040] Secondly, by arranging the first trimming arm 301 and the second trimming arm 302 left and right and maintaining a symmetrical state in the case of vertical projection, when the inductor 13 is placed inside the support sleeve 10, the two pins of the inductor 13 are respectively inserted into the cutting openings 4 on the first trimming arm 301 and the second trimming arm 302, so that the two pins can be trimmed by the first trimming arm 301 and the second trimming arm 302 respectively.

[0041] Meanwhile, in order to control the first trimming arm 301 and the second trimming arm 302 at different heights to meet the requirements of different trimming lengths for the two pins of the inductor 13, such as Figure 3 As shown, a pad 15 is provided between the bottom surface of the first trimming arm 301 and the bottom inner wall of the limiting groove 17. By setting the pad 15 at the bottom of the first trimming arm 301 and the pad 15 at the bottom of the second trimming arm 302 to different heights, the pad 15 can be sleeved on the outside of the column 14 and adapted to be connected inside the limiting groove 17, thereby raising the first trimming arm 301 or the second trimming arm 302. When pads 15 of different heights are selected, there can be a height difference between the first trimming arm 301 and the second trimming arm 302 to meet the actual pin trimming requirements.

[0042] In addition, multiple support sleeves 10 are installed between the bottoms of adjacent first trimming arms 301 and second trimming arms 302, and are adapted to the height of the first trimming arms 301 and second trimming arms 302, so as to support the first trimming arms 301 and second trimming arms 302.

[0043] The above design opens multiple cutouts 4 in a row inside the first trimming arm 301 and the second trimming arm 302, and controls the height of the first trimming arm 301 and the second trimming arm 302 after assembly by adding a pad 15 in the limiting groove 17 at the base plate 6. This allows the two pins on the inductor 13 to extend into the two cutouts 4 of different heights respectively. During the pin trimming process, pins of different lengths can be obtained to meet actual usage requirements.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
