[0034] The existing integrated inductor adopts an integrated molding process: the winding body is buried inside the metal magnetic powder, and the metal magnetic powder is die-cast to form the inductor base. The winding body has a pair of pins and extends to both sides of the base. After completing the die-casting process, the two pins need to be folded upwards, the inductor pins need to be cut to obtain a predetermined pin length, and finally the pins are bent toward the base and pressed against the base to form the inductor chip pins. In order to improve processing efficiency, the existing production usually uses an inductor pin forming machine to complete the above process.

[0035] Existing inductor pin forming machines usually include a material channel, and the inductor base is used to arrange the inductor in a straight line on the material channel. Due to the use of arranged sliding feeding, the inductor is easy to get stuck in the material channel and cause downtime, affecting production efficiency; and the linear assembly line processing is used, and the production line is relatively long.

[0036] To solve the above problems, please refer to Figures 1 to 3 The utility model proposes a turntable type inductor pin forming device 1000, comprising a frame 1, a turntable mechanism 2, a mounting fixture 3, a cutting mechanism 4, a bending mechanism 5 and an ejection mechanism 6. The turntable mechanism 2 comprises a turntable 21 and a rotating driving member. The turntable 21 is mounted on the frame 1. The output end of the rotating driving member is connected to the turntable 21 to drive the turntable 21 to rotate. A plurality of mounting stations are arranged on the turntable 21. The mounting fixture 3 is mounted on the mounting station. The mounting fixture 3 is formed with a plurality of mounting grooves 31. to place the inductor 200; the cutting mechanism 4 is installed on the frame 1 to cut the redundant pins of the inductor 200; the bending mechanism 5 is installed on the frame 1 to bend the inductor 200 into shape; the ejection mechanism 6 is installed on the frame 1 to take the bent inductor 200 out of the mounting fixture 3; the cutting mechanism 4, the bending mechanism 5 and the ejection mechanism 6 are arranged in sequence around the turntable 21, so that the mounting fixture 3 can be processed by the cutting mechanism 4, the bending mechanism 5 and the ejection mechanism 6 in sequence.

[0037] The technical solution of the utility model sets a plurality of installation stations on the turntable mechanism 2, and installs the unformed inductor 200 through the installation fixture 3. The installation fixture 3 is driven by the turntable 21 and passes through the cutting mechanism 4, the bending mechanism 5 and the ejection mechanism 6 in sequence to cut, bend and eject the inductor 200, thereby realizing the automation of the processing of the inductor 200. The movement of the turntable 21 replaces the linear production of the assembly line, thereby reducing the space occupied by the turntable type inductor pin forming device 1000, avoiding the possibility of material jamming during the production process, and improving the production efficiency.

[0038] In an optional embodiment, in order to facilitate the collection of the cut inductor bracket 200 from the turntable 21, a plurality of mounting holes 211 are formed on the periphery of the turntable 21, and a mounting fixture 3 is arranged on opposite sides of a mounting hole 211 along the length direction. The mounting hole 211 is formed with an escape space relative to the mounting fixture 3 so that the inductor bracket can pass through the escape space. Please refer to Figures 1 to 3. Figure 3 The mounting fixture 3 is arranged in a long strip shape, and the two ends of the mounting fixture 3 are respectively connected to the opposite sides of the mounting hole 211. The mounting hole 211 is respectively provided with avoidance spaces relative to the two sides of the mounting fixture 3, so that after the cutting mechanism 4 cuts the inductor 200 from the inductor bracket, the inductor bracket passes through the mounting hole 211 under the action of its own gravity and falls into the collection container sent down, so as to collect the mounting brackets in a centralized manner.

[0039] In an optional embodiment, in order to facilitate cutting the inductor 200 from the inductor bracket, a placement platform 32 is formed at both ends of the mounting fixture 3 in the width direction, and the pins at both ends of the inductor 200 are respectively placed on a placement platform 32. Figure 1 and Figure 3 By setting a placement table 32 at both ends of the installation fixture 3, the inductor pin 202 can be placed on the placement table 32, and the inductor bracket is exposed at the edge of the placement table 32. In this way, the inductor bracket and the inductor pin 202 are distinguished and isolated by the placement table 32, which is convenient for finding the cutting position of the inductor pin 202 and the inductor bracket when cutting the inductor 200, so as to ensure the accuracy and consistency of the cutting of the inductor 200, which is beneficial to ensure the quality of the inductor 200 after cutting.

[0040] In an optional embodiment, in order to cut the inductor 200 from the inductor pin 202, the cutting mechanism 4 includes a cutting piece 41 and a first driving piece 42. The cutting piece 41 is arranged at the outer edge of the placement table 32. The output end of the first driving piece 42 is connected to the cutting piece 41, and drives the cutting piece 41 to move up and down to cooperate with the outer edge of the placement table 32 to cut the inductor 200. Please refer to Figure 1 and Figure 3 The cutting piece 41 is arranged above the mounting fixture 3 and is located at the outer edge of the placement table 32. The cutting piece 41 is driven by the driving member to move up and down to form a shearing effect with the outer edge of the placement table 32 to cut the inductor 200 from the inductor bracket. Optionally, the cutting piece 41 has multiple cutting parts, and one cutting part is arranged corresponding to one inductor pin 202, so that the cutting piece 41 can simultaneously cut off multiple inductors 200 on the inductor bracket during one lifting and moving process, thereby improving the cutting efficiency.

[0041] Furthermore, in order to simultaneously cut off the pins at both ends of the inductor 200, cutting pieces 41 are provided at both ends of the width direction of the mounting fixture 3, and the output end of the first driving piece 42 is connected to the driving pieces at both ends to simultaneously cut off the pins at both ends of the inductor 200. Figure 1 , cutting pieces 41 are respectively provided at both ends of the mounting fixture 3 in the width direction, and the cutting pieces 41 are connected to the driving member so as to rise or fall simultaneously under the driving of the driving member to synchronously cut the inductor pins 202 at both ends. Optionally, the cutting pieces 41 at both ends can also be designed in an integrated manner, which can further ensure the precision of synchronous cutting at both ends and improve the stability of cutting the inductor 200.

[0042] In an optional embodiment, in order to achieve the bending process of the cut inductor 200, the bending mechanism 5 includes a pushing member 51, a second driving member 52, a bending member 53 and a third driving member 6. The pushing member 51 is arranged above the installation groove 31 in the vertical direction. The output end of the driving member is connected to the pushing member 51, and can drive the pushing member 51 to move downward to push the inductor 200 into the bottom of the installation groove 31. The bending member 53 is arranged above the placement table 32 along the width direction of the installation fixture 3. The output end of the third driving member 6 is connected to the bending member 53 to drive the bending member 53 to push the pins of the inductor 200 to bend inward. The bending mechanism 5 is provided on both sides of the installation fixture 3 to simultaneously bend the pins at both ends of the inductor 200 inward. Please refer to Figures 1 to 3 In order to facilitate the bending process of the inductor pin 202, in actual design, the depth of the mounting groove 31 can be greater than the depth of the inductor 200. In this way, when the inductor 200 before cutting is placed on the mounting fixture 3, since the placement table 32 is at the highest position, the pins at both ends of the inductor 200 are overlapped on the placement table 32, and the inductor body 201 in the middle is still in a suspended state. When the inductor pin 202 is cut, the rotary drive member drives the turntable 21 to rotate and move the inductor 200 from the cutting mechanism 4 to the bending mechanism 5, and the second driving member 52 drives the pushing member 51 to The inductor 200 moves downward to push the inductor 200 into the bottom of the installation groove 31. During the downward movement of the inductor 200, since the size of the installation groove 31 is almost equal to the size of the inductor body 201, the inductor pins 202 at both ends of the inductor 200 are bent upward under the action of the side wall of the installation groove 31. When the inductor body 201 contacts the bottom wall of the installation groove 31, the direction of the inductor pins 202 changes from the horizontal direction to the vertical direction. At this time, the inductor pins 202 are bent inwardly by the bending mechanisms 5 arranged on both sides of the width direction of the installation jig 3 to achieve the bending forming of the inductor pins 202. The third driving member 6 drives the bending member 53 to move horizontally to bend the inductor pins 202 protruding from the end of the installation groove 31 inwardly, and the bending mechanisms 5 are arranged on both sides of the installation jig 3 to achieve the bending of the inductor pins 202 at both ends of the inductor body 201 at the same time, thereby improving the efficiency of the bending process.

[0043] Optionally, in order to realize automatic control of the second driving member 52 and the third driving member 6, a pressure sensor is provided at the bottom of the installation slot 31, and the pressure sensor is electrically connected to the second driving member 52 and the third driving member 6. By providing a pressure sensor at the bottom of the installation slot 31, the pressure sensor can be used to sense whether the inductor body 201 has moved to the bottom of the installation slot 31. When the pressure sensor detects the pressure from the inductor body 201 above, it means that the inductor body 201 has reached the bottom of the installation slot 31 under the push of the push member 51. The controller controls the second driving member 52 to stop moving, and drives the third driving member 6 to move to perform the bending process on the inductor pin 202. In this way, the automation of the bending process of the inductor pin 202 is realized, and the efficiency of the bending process is improved.

[0044] In an optional embodiment, in order to ensure the bending effect of the inductor pin 202, the bending member 53 includes a push rod and a roller. A receiving groove is formed at the bottom of the push rod. The roller is installed in the receiving groove and partially protrudes from the receiving groove to roll and compact the bent pin. The side of the push rod facing the installation groove 31 is used to abut against the inductor pin 202 and bend it. The roller is set on the top of the push rod. After the inductor pin 202 is bent, the push rod continues to move forward, so that the roller rolls the bent inductor pin 202 to roll the inductor pin 202 flat, so that it fits tightly with the top wall of the inductor body 201, and ensures the bending quality of the inductor 200.

[0045] In an optional embodiment, in order to remove the inductor 200 after bending, the ejection mechanism 6 includes an ejection member 61 and a fourth driving member 62. The bottom wall of the installation slot 31 is formed with an ejection hole 33. The ejection member 61 is arranged below the ejection hole 33 in the vertical direction. The output end of the driving member is connected to the ejection member 61 to drive the ejection member 61 to move up and down to eject the inductor 200 in the installation slot 31. Please refer to Figure 2 and Figure 3 An ejection hole 33 is provided at the bottom of each mounting groove 31. The size of the ejection hole 33 is smaller than the size of the inductor body 201, so that there is space at the bottom of the mounting groove 31 to set the pressure sensor. The ejection rod is penetrated through the ejection hole 33. When the fourth driving member 62 drives the ejection rod to move upward, the ejection rod lifts the inductor body 201 to eject the inductor 200 from the mounting groove 31, and falls into the collection container below through the through hole of the installation station on the turntable 21 for collection, thereby completing the entire processing and forming process of the inductor 200.

[0046] In an optional embodiment, in order to realize automatic loading of the inductor 200, the rotary disc type inductor pin forming device 1000 further includes a loading mechanism, which is mounted on the frame 1, and includes a suction cup and a fifth driving member, and the output end of the fifth driving member drives the suction cup to suck the inductor 200 and place it on the installation fixture 3. Optionally, the suction cup structure is set to suck the semi-finished structure with the inductor bracket, and it is placed in the installation fixture 3 accordingly, so as to realize automatic loading of the inductor 200. In order to improve the accuracy of the suction cup sucking and placing the semi-finished assembly of the inductor 200, a CCD visual camera can be set on the frame 1 to assist the suction cup to move forward and ensure the stability of loading.

[0047] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
