The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0018] like Figures 1 to 12A common-mode inductor coil removal forming machine is characterized in that it includes a workbench 1, a fixed mold 2 is provided on the upper side of the workbench 1, and the fixed mold 2 is provided with a lower limit groove 21 for placing the common-mode inductor, and a clamping structure 3 is provided at the upper end of the lower limit groove 21, and the clamping structure 3 includes an upper limit block 31 that moves up and down, and a coil withdrawal structure 4 is provided on both sides of the lower limit groove 21, which is used to pull the coil port of the common-mode inductor to be removed from the spiral state to a certain arc, and a top foot structure 5 is provided on the lower side of the lower limit groove 21, which is used to punch the coil port pulled apart by a certain arc to a vertical tangent state with the coil, and shaping structures 6 are also provided at both ends of the lower limit groove 21, which are used to punch the coil port in the vertical tangent state to a vertical vertical state in the middle position of the coil.

[0019] The common-mode inductor to be processed is placed in the lower limit groove 21 of the fixed mold 2, and then is pressed under the action of the clamping structure 3. Under the action of the coil-retracting structure 4, the common-mode inductor coil port is pulled from the spiral state to a certain arc. Under the action of the top foot structure 5, the coil port pulled to a certain arc is punched to a vertical tangent state with the coil. Under the action of the shaping structure 6, the vertical tangent state coil port is punched to a vertical vertical state in the middle of the coil, thereby completing the coil unwinding and forming work of the common-mode inductor. The whole process is automated, and the coil unwinding and forming can be completed efficiently and accurately.

[0020] At this time, in order to fix the common-mode inductor to be processed, in this embodiment, the fixed mold 2 includes a fixed plate 22 fixed on the upper side of the workbench 1, the lower limit groove 21 is located on the upper side of the fixed plate 22, and a transverse groove 23 connected to the lower limit groove 21 is provided on one side of the lower limit groove 21, and the fixed plate 22 is also provided with a vertical groove 24 running through from top to bottom, and the vertical groove 24 is located on the side of the lower limit groove 21 and is connected to the transverse groove 23. The lower limit groove 21 is an arc shape adapted to the lower side of the common-mode inductor to be processed, and at this time, one end of the lower limit groove 21 is provided with a connected transverse groove 23 and a vertical groove 24, and after the common-mode inductor to be processed is placed in the lower limit groove 21, the common-mode inductor to be processed is positioned to facilitate the subsequent processing process.

[0021] Since the coil port of the common-mode inductor to be removed is relatively fixed to the position of the coil pulled out from the other end, by fixing the coil pulled out from the other end, it can be determined that the coil of the common-mode inductor to be removed is located in the lower limit groove 21. Therefore, the fixed mold 2 also includes a positioning structure 25, and the positioning structure 25 is a positioning hole 251 set on the fixed plate 22. When the lead wire extended from one end of the common-mode inductor coil is inserted into the positioning hole 251, the coil port of the common-mode inductor to be removed is located at the intersection of the lower limit groove 21, the horizontal groove 23, and the vertical groove 24, and the opening of the coil port of the common-mode inductor to be removed faces inward. When the common-mode inductor to be processed is placed in the lower limit groove 21, and the lead wire extended from one end of the common-mode inductor coil is inserted into the positioning hole 251, it can be ensured that the coil to be removed is located in a relatively fixed position, so as to facilitate the subsequent removal of the coil and ensure that the coil can be removed from the end position during the removal process.

[0022] As another embodiment of the positioning structure 25 of the fixed mold 2, the fixed mold 2 also includes a positioning structure 25, and the positioning structure 25 includes a positioning plate, and the positioning plate is fixed on the upper side of the fixed plate 22, and the positioning plate is set with a positioning groove. When the lead wire extended from one end of the common-mode inductor coil is accommodated in the positioning groove, the coil port of the common-mode inductor to be removed is located at the intersection of the lower limit groove 21, the horizontal groove 23, and the vertical groove 24, and the coil port of the common-mode inductor to be removed is opened toward the inside. The positioning structure 25 is set at the upper side of the fixed plate 22 and is set as a positioning groove. The coil is rotated to a certain angle. When the common-mode inductor to be processed is placed in the lower positioning groove, the lead wire is just stuck in the positioning groove, thereby determining the position of the common-mode inductor to be processed. At this time, the positioning groove adopts a side slot form, which is convenient for removal before and after processing.

[0023] The back-loop structure 4 is used to pull the coil end out of a certain curvature to facilitate lifting the coil in the subsequent work process. Therefore, in this embodiment, the back-loop structure 4 includes a back-loop cylinder 41 symmetrically arranged on the outside of the lower limit groove 21, and the piston rod of the back-loop cylinder 41 is connected with a hook foot block 42, and the hook foot block 42 is clamped in the transverse groove 23 and reciprocates in the transverse groove 23. A groove 421 is provided on the upper side of the end of the hook foot block 42, and a protrusion 422 is formed between the groove 421 and the end of the hook foot block 42. When the common-mode inductor is placed in the lower limit groove 21, the coil port of the common-mode inductor to be removed is located in the groove 421. When the back-loop cylinder 41 acts to make the hook foot block 42 move toward the outside of the transverse groove 23, the protrusion 422 of the hook foot block 42 abuts against the coil port of the common-mode inductor to be removed, thereby pulling the coil port of the common-mode inductor to be removed from the spiral state to a certain curvature. After the common-mode inductor to be processed is placed in the lower limit groove 21, the positioning structure 25 is used to position the coil port that needs to be removed, so that the coil port is located in the groove 421. When the coil-removing cylinder 41 moves outward and the hook foot block 42 moves outward, the protrusion 422 also moves outward. The protrusion 422 abuts against the coil port during the movement. When the protrusion 422 continues to move, the coil port is stretched to a certain curvature under the action of the protrusion 422 until it is separated from the coil port and the protrusion 422. At this time, the coil port is stretched to a certain curvature, and the hook foot block 42 moves to the outside of the common-mode inductor, that is, moves to the outside of the vertical groove 24. The hook foot block 42 will not affect subsequent work.

[0024] After the common-mode inductor to be removed is stretched to a certain curvature, it is necessary to lift one side of the common-mode inductor coil port to an upward state. In this embodiment, the top foot structure 5 includes a top foot cylinder 51, and the piston rod of the top foot cylinder 51 is connected to a top foot rod 52. The top foot rod 52 is clamped in the vertical groove 24 and moves up and down along the vertical groove 24. When the top foot rod 52 moves upward, the coil port that is pulled open to a certain curvature is punched to a state of vertical tangency with the coil. Under the action of the top foot cylinder 51, the top foot rod 52 moves up and down in the vertical groove 24, and contacts the coil port when it moves to the position where the coil port is pulled open to form a certain curvature. In the process of continuing to move upward, the coil port is opened until the top foot rod 52 moves to the upper stroke position. In this way, under the action of the top foot rod 52, the coil port can be made to face upward. After the top foot rod 52 moves to the upper stroke position, it moves downward to restore to its original position under the action of the top foot cylinder 51 to avoid affecting the subsequent shaping process.

[0025] After the coil port is stamped to the upward state, in order to ensure the integrity of all coils and facilitate the subsequent fixing of the coils and terminals, in this embodiment, the shaping structure 6 includes a shaping cylinder 61 on the upper side of the workbench 1, and the piston rod of the shaping cylinder 61 is connected to a shaping block 62, and the shaping block 62 corresponds to the common mode inductor coil port. The shaping block 62 moves horizontally under the action of the shaping cylinder 61, and is used to stamp the vertical tangent state coil port to the vertical state in the middle position of the coil. The shaping cylinder 61 is set horizontally, and then the shaping block 62 moves horizontally. During the movement of the shaping block 62, the pulled upward coil is stamped to a vertical state.

[0026] In the process of the top foot structure 5 lifting the coil port upward and the shaping structure 6 punching the coil port left and right, in order to make the coil deform in a set direction, a deformation path needs to be set. Specifically, in the present embodiment, the upper limit block 31 includes an upper limit groove 311 adapted to the common mode inductor, and both sides of the upper limit block 31 are provided with punching grooves 312 adapted to the width of the shaping block 62. When the top foot rod 52 moves upward under the action of the top foot cylinder 51, the coil port with an arc of the common mode inductor is punched into the punching groove 312 (the common mode inductor coil port faces downward and upper side). A vertical positioning portion 313 is provided in the middle of the upper limit block 31. The vertical positioning portion 313 is located on the upper side of the middle position of the common mode inductor coil in the upper limit groove 311 and the lower limit groove 21. Under the action of the shaping cylinder 61, the shaping block 62 punches the removed coil wire located in the punching groove 312 to fit with the vertical positioning portion 313. When the common-mode inductor to be processed is placed in the lower limit groove 21, the upper limit block 31 is moved downward so that the upper limit block 31 presses the common-mode inductor to be processed. At this time, the coil of the common-mode inductor to be processed that needs to be removed is opposite to the stamping groove 312, and when the top foot rod 52 of the top foot structure 5 moves up and down, it is also located in the stamping groove 312. Therefore, when the top foot rod 52 moves upward to act on the coil, the coil is also located in the stamping groove 312 after deformation, and then when the shaping block 62 acts on the coil, the coil is also located in the stamping groove 312 and deformed, so that the coil can be guided to deform to the set shape.

[0027] The upper limit block 31 is driven up and down by a cylinder, which is fixed to the upper side of the workbench 1 through a bracket and a plate. The upper limit block 31 is then controlled to move up and down under the action of the cylinder. The disassembly and forming process of the common mode inductor coil is carried out when the upper limit block 31 moves downward to the upper side of the fixed plate 22 to ensure that the coil is deformed in the preset direction.

[0028] During the movement of the shaping block 62, in order to ensure the stable movement of the shaping block 62, in this embodiment, a guide block 7 is provided on the upper side of the fixing plate 22, and the guide block 7 is fixed on the upper side of the transverse groove 23 of the fixing plate 22, and is used to limit the lateral movement of the hook foot block 42 in the transverse groove 23. The guide block 7 is provided with a guide groove 71 adapted to the shaping block 62, and the shaping block 62 is located in the guide groove 71 and moves laterally along the guide groove 71. At this time, the guide block 7 is located on the upper side of the fixing plate 22, and the guide block 7 can also be used to limit the reciprocating movement of the hook foot block 42.

[0029] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
