Description

Technical Field

[0001] This utility model relates to a short wire splitting mechanism, specifically to an SQ common mode inductor short wire splitting mechanism. Background Technology

[0002] During the production process of SQ common mode inductors, after the magnetic core is wound with the coil, the short wire end needs to be separated from the coil and swung to the position where the pins of the housing are wrapped, so as to facilitate the subsequent pin wrapping operation.

[0003] Existing short wire splitting mechanisms typically use a splitting knife in conjunction with a rotating product holder to push the short wire end to the stopping position, thus facilitating subsequent foot wrapping operations. However, in existing splitting mechanisms, the inductor is directly fixed to the detection seat. The splitting knife pushes the short wire end away from the coil, and the detection seat is rigidly connected. This makes it difficult to avoid the problem of excessive tolerance in the stopping range of the short wire end after splitting due to production and assembly errors, resulting in poor splitting stability. Therefore, an SQ common mode inductor short wire splitting mechanism is proposed to solve the problems existing in the current technology. Utility Model Content

[0019] See Figures 1-7As shown, the technical solution adopted in this specific embodiment is as follows: It includes a wire splitting servo module 1, a magnetic core pressing mechanism 2 is arranged above the wire splitting servo module 1, a long wire cycloidal mechanism 3 is arranged above the middle of the wire splitting servo module 1, and the long wire cycloidal mechanism 3 is located below the front end of the magnetic core pressing mechanism 2. A product wire splitting seat 4 is arranged on the top of the long wire cycloidal mechanism 3. A right wire splitting knife rotation mechanism 6 and a left wire splitting knife rotation mechanism 7 are respectively arranged on both sides of the wire splitting servo module 1, corresponding to the product wire splitting seat 4. A wire joining mechanism 5 is arranged above the end of the wire splitting servo module 1, and the front end of the wire joining mechanism 5 corresponds to the vertical axis above the product wire splitting seat 4. In this embodiment... In this example, a long-wire cycloidal mechanism is used to oscillate the long end of the product, thereby driving the short wire end to rotate in coordination with the left and right wire-separating knife rotation mechanism. After the wire-separating servo module is set up, it can drive the long-wire cycloidal mechanism and the product wire-separating seat to move, so as to move the product to the most accurate wire-separating position. After the product is fixed, the magnetic core is pressed and fixed by the magnetic core pressing mechanism to ensure that the product will not move during the wire-separating process, thus improving the accuracy and precision of wire-separating. After the wire-separating is completed, the wire-combining mechanism presses the short wire end that has been issued, thereby facilitating subsequent operations. The fully automated mechanism not only has high wire-separating efficiency, but also more accurate wire-separating operation.

[0020] More specifically, a photoelectric detection mechanism 8 is provided on one side of the magnetic core pressing mechanism 2. The light path of the detection head of the photoelectric detection mechanism 8 is aligned with the product distribution seat 4. In order to ensure the accuracy of product placement, the photoelectric detection mechanism is set up to detect the placed product. The detection result is fed back to the control system to trigger the subsequent automated operation process.

[0021] More specifically, the long-line cycloidal mechanism 3 includes a fixed shaft 31, on which a first cycloidal gear 32 and a second cycloidal gear 34 are sequentially connected by bearings. A first swing arm 33 and a second swing arm 35 are respectively mounted on the first cycloidal gear 32 and the second cycloidal gear 34. A stabilizing spring 36 is sleeved on the top of the fixed shaft 31, with a portion of the stabilizing spring 36 located within the second cycloidal gear 32. The fixed shaft 31 extends into the product wire separator 4, causing the stabilizing spring 36 to abut against the product wire separator 4. In this embodiment... In order to improve the fixing stability of the common mode inductor product and to achieve a continuous fastening effect in conjunction with the core pressing mechanism, a stabilizing spring is set up to cooperate with the product wire divider. The stabilizing spring can continuously provide a clamping force to the product wire divider, thereby achieving the product fixing stability. In the long wire cycloidal mechanism, two cycloidal gears can drive two swing arms to rotate, thereby enabling the long wire to be turned, causing the short wire end to swing. When the short wire end swings, it enters the right wire divider rotation mechanism and the left wire divider rotation mechanism for subsequent wire twisting and wire splitting operations.

[0022] More specifically, the product wire divider 4 is fitted with a wire divider post 41, and a product fixing groove 42 is provided on the rear side of the wire divider post 41. The side of the product wire divider 4 is provided with an installation groove 43 corresponding to the fixing shaft 31. The wire divider post on the product wire divider cooperates with the long wire and is also a limiting structure. It will cause the long wire to deform under the action of the two swing arms to complete the wire-pulling swing operation. The product fixing groove is used for product placement and is fixed by the magnetic core pressing mechanism.

[0023] More specifically, the splitting servo module 1 includes a splitting servo module base 11, a splitting servo motor 12 is provided at the end of the splitting servo module base 11, a guide rail 14 is provided at the front end of the splitting servo module base 11, a splitting module slide 15 is slidably connected on the guide rail 14, and a transmission screw 13 is connected to the output shaft end of the splitting servo motor 12 and threadedly connected to the splitting module slide 15. In this embodiment, since the long wire cycloidal mechanism is set on the splitting module slide, the specific position of the long wire cycloidal mechanism can be adjusted by driving the splitting servo motor to move the splitting module slide on the guide rail, so as to obtain the best splitting effect.

[0024] More specifically, a long-line swing drive cylinder 16 is provided at the center of the top front end of the slide block 15 of the splitting module. A push plate 111 is connected to the push rod of the long-line swing drive cylinder 16. A cycloidal push rod seat 17 is fixedly connected to the push plate 111. A cycloidal fixing block 18 is provided at the rear end of the cycloidal push rod seat 17. A first cycloidal toothed plate 19 is provided on the top of the cycloidal fixing block 18. A second cycloidal toothed plate 110 is provided on the bottom side of one side of the cycloidal fixing block 18. The first cycloidal toothed plate 19 meshes with the second cycloidal gear 34, and the second cycloidal toothed plate 110 meshes with the first cycloidal gear 32. In this embodiment, in order to realize the prying of the two long lines on the product, two cycloidal toothed plates are set to cooperate with two cycloidal gears. Under the drive of the long-line swing drive cylinder, the two cycloidal toothed plates are driven to move, thereby driving the rotation of the two cycloidal gears, thereby driving the two cycloidal plates to rotate and realize the prying of the long lines.

[0025] More specifically, the wire-combining mechanism 5 includes a wire-combining mechanism bracket 51. A wire-combining drive cylinder 52 is provided on the top of the wire-combining mechanism bracket 51. The wire-combining drive cylinder 52 is connected to a fixed plate via a push rod. A wire-combining push plate 53 is connected to the fixed plate. A wire-combining cylinder 54 is provided at the bottom front end of the wire-combining push plate 53. A wire-combining guide rail seat 55 is connected to the push rod at the front end of the wire-combining cylinder 54. Symmetrical pneumatic wire-combining blocks 56 are slidably connected inside the wire-combining guide rail seat 55. A wire-combining lever 57 is provided at the bottom of the pneumatic wire-combining block 56. In this embodiment, after the short wire is split, the short wire ends need to be combined. The wire-combining drive cylinder can drive the pneumatic wire-combining block to move to the wire-combining stopping position. In the initial action, after the long wire is swung, the pneumatic wire-combining block will limit the short wire ends so that the short wire ends can stop. The stopping width is achieved by controlling the movement of the pneumatic wire-combining block by the wire-combining cylinder. After the splitting is completed, the two pneumatic wire-combining blocks are driven to merge, thereby completing the wire-combining operation.

[0026] More specifically, the right wire splitter rotation mechanism 6 includes a right wire splitter rotation seat 61, a right wire splitter rotation motor 62 is disposed inside the right wire splitter rotation seat 61, a right wire splitter holder 63 is connected to the output shaft end of the right wire splitter rotation motor 62, and a right wire splitter 64 is disposed on the right wire splitter holder 63. The left wire splitter rotation mechanism 7 includes a left wire splitter rotation seat 71, a left wire splitter rotation motor 72 is disposed inside the left wire splitter rotation seat 71, a left wire splitter holder 73 is disposed at the output shaft end of the left wire splitter rotation motor, and a left wire splitter 74 is disposed on the left wire splitter holder 73. In this embodiment, two wire splitter rotation mechanisms are set up to achieve wire splitting of short wire ends. Through the two wire splitters, when the short wire ends move, the wire splitters rotate and insert into the top of the coil and pass through the loop formed by the short wire ends. By rotating the wire splitters, the short wire ends are twisted, and the wire splitting is completed.

[0027] The working principle of this utility model is as follows: Before the separation begins, the separation servo motor 12 is started, driving the separation module slide 15 to move back and forth, adjusting the specific positions of the long-wire cycloidal mechanism 3 and the product separation seat 4. Then, the product is placed on the product separation seat 4 through the external material handling mechanism. The positions of the long-wire cycloidal mechanism 3 and the product separation seat 4 are finely adjusted again until they move below the magnetic core pressing mechanism 2. The magnetic core pressing mechanism 2 is started to press down the magnetic core, so that the bottom of the magnetic core is subjected to the force of the stabilizing spring 36, thereby continuously obtaining the pressing force, ensuring more stable and more accurate separation during the separation operation. The long-wire swing drive cylinder 16 is started, driving the first cycloidal tooth plate 19 and the second cycloidal tooth plate 110 to move, thereby driving the first cycloidal... Gear 32 and the second cycloidal gear 34 rotate, thereby driving the first swing arm 33 and the second swing arm 35 to rotate. Since the first swing arm 33 and the second swing arm 35 are at the edge of the long line of the product, they can press the long line inward and swing it, causing the short line end to swing together and enter the right splitting knife 64 and the left splitting knife 74. Due to the limiting effect of the two swing arms, the short line end can also stop within a small tolerance range, ensuring accurate insertion into the right splitting knife 64 and the left splitting knife 74. Then, the right splitting knife rotation mechanism 6 and the left splitting knife rotation mechanism 7 are activated, causing the right splitting knife 64 and the left splitting knife 74 to twist the short line end, completing the splitting of the short line end. After the splitting is completed, all equipment is reset, and the split product is taken out to enter the next splitting operation process.
