Description

Technical Field

[0001] The utility model relates to the technical field of chip inductor manufacturing, in particular to a copper wire vertical winding device for a chip inductor. Background Technique

[0002] An inductor is an electronic component that can convert electrical energy into magnetic energy and store it. An inductor has a certain inductance, and it only impedes the change of current. If the inductor is in a state without current passing through, when the circuit is switched on, it will try to impede the current from flowing through it; if the inductor is in a state with current passing through, when the circuit is switched off, it will try to maintain the current unchanged. An inductor is also called a choke, a reactor, or a dynamic reactor. In the production process of an inductor, it is necessary to wind the coil first. For some, the two ends of the wound coil are welded to the lead frame, and for some, there is no need for a lead frame. The coil is placed into the housing formed by iron powder molding, then iron powder is filled, and then hot pressing or cold pressing is performed for shaping. The two ends of the coil or the two ends of the lead frame are bent, and finally, the bent parts are stripped of paint and electroplated to form two electrodes.

[0003] In the prior art, after the copper wire is wound into a coil, it needs to be taken off and then assembled onto the pin pressing device to flatten the leads of the coil. As a result, when the coil is transferred and processed between the two devices, a large amount of processing time is wasted, reducing the production efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a copper wire vertical winding device for a chip inductor. Through the coordinated use of the wire-releasing copper coil, copper wire tube, driving mechanism, winding shaft, and wire-clamping and wire-cutting mechanism, the copper wire is automatically wound into a coil, and through the arranged flattening mechanism, the two leads of the coil are contacted and the leads are flattened to facilitate subsequent spot welding with the chip, integrating wire winding, wire clamping, wire cutting, blanking, and bending, reducing manual intervention, and greatly improving the production efficiency.

[0005] The utility model provides the following technical solution. A copper wire vertical winding device for a chip inductor includes: a bottom plate and a winding shaft fixing plate fixedly connected to the top of the bottom plate. A winding shaft is rotatably connected to the winding shaft fixing plate. One end of the winding shaft is connected with a wire-clamping and wire-cutting mechanism, and the other end of the winding shaft passes through the winding shaft fixing plate and is connected with a driving mechanism. Two copper wire tubes are fixedly penetrated through the winding shaft fixing plate. One side of the rear end of the bottom plate is fixedly connected with a wire-releasing copper coil fixing frame. Two wire-releasing copper coils are rotatably connected to the wire-releasing copper coil fixing frame. A flattening mechanism is installed on one side of the front end of the bottom plate, and the flattening mechanism corresponds to the position of the wire-clamping and wire-cutting mechanism.

[0006] As a preferred embodiment of the present utility model, the driving mechanism includes a support seat fixedly connected to the top of the bottom plate, a motor installed on the top of the support seat, a motor driving gear fixedly connected to the output end of the motor, and a winding shaft driven gear fixedly connected to one end of the winding shaft. The winding shaft driven gear meshes with the motor driving gear.

[0007] As a preferred embodiment of the present utility model, the wire clamping and cutting mechanism includes a winding plate fixedly sleeved on the winding shaft. On both sides of the winding shaft on the winding plate, a pair of mounting seats are symmetrically and fixedly connected. An air-operated clamping jaw cylinder is fixedly connected to the mounting seat, and an air-operated clamping jaw is fixedly connected to the output end of the air-operated clamping jaw cylinder.

[0008] As a preferred embodiment of the present utility model, an air-operated scissors is installed on one side of the mounting seat close to the winding shaft.

[0009] As a preferred embodiment of the present utility model, one end of the copper wire tube extends to the position where the air-operated clamping jaw is located.

[0010] As a preferred embodiment of the present utility model, a blanking mechanism is installed between the winding plate and the winding shaft.

[0011] As a preferred embodiment of the present utility model, the flattening mechanism includes a flattening mechanism fixing frame fixedly connected to the bottom plate. An air cylinder of the flattening mechanism is installed on one side of the flattening mechanism fixing frame close to the winding shaft, and a flattening block is fixedly connected to the output end of the air cylinder of the flattening mechanism.

[0012] The beneficial effects of the present utility model are as follows: Through the coordinated use of the wire-releasing copper coil, the copper wire tube, the driving mechanism, the winding shaft, and the wire clamping and cutting mechanism, the copper wire is automatically wound into a coil. And through the arranged flattening mechanism, the two leads of the coil are brought into contact, and the leads are flattened to facilitate subsequent spot welding with the chip. The two processes of copper wire winding and electrode bending are integrated into one device. After winding, the two wire ends are directly bent into electrodes without transferring the coil. Moreover, the vertical winding of the copper wire coil can be fully automatic, integrating wire winding, wire clamping, wire cutting, blanking, and bending, reducing manual intervention and greatly improving production efficiency.

[0022] Embodiment

[0023] As Figures 1 to 7 shown, a copper wire vertical winding device for a chip inductor includes: a base plate 1 and a winding shaft fixing plate 2 fixedly connected to the top of the base plate 1. A winding shaft 3 is rotatably connected to the winding shaft fixing plate 2. One end of the winding shaft 3 is connected to a thread clamping and cutting mechanism 4, and the other end of the winding shaft 3 passes through the winding shaft fixing plate 2 and is connected to a driving mechanism 6. Two copper wire tubes 5 are fixedly inserted through the winding shaft fixing plate 2. One side of the rear end of the bottom of the base plate 1 is fixedly connected to a fixed frame 7 for unwinding copper coil, and two unwinding copper coils 8 are rotatably connected to the fixed frame 7 for unwinding copper coil. A flattening mechanism 9 is installed on one side of the front end of the base plate 1, and the flattening mechanism 9 corresponds to the position of the thread clamping and cutting mechanism 4. During use, the copper wires on the two unwinding copper coils 8 are respectively passed through the two copper wire tubes 5 and clamped by the thread clamping and cutting mechanism 4, and then the driving mechanism 6 is used to drive the winding shaft 3 and the thread clamping and cutting mechanism 4 to rotate, so that the copper wires are wound on the winding shaft 3 to form a coil, enabling the vertical winding of the copper wire coil of the chip inductor to be fully automatic, reducing manual intervention, and greatly improving the production efficiency.

[0024] In this embodiment, the driving mechanism 6 includes a support base 601 fixedly connected to the top of the bottom plate 1, a motor 602 mounted on the top of the support base 601, a motor driving gear 603 fixedly connected to the output end of the motor 602, and a winding shaft driven gear 604 fixedly connected to one end of the winding shaft 3. The winding shaft driven gear 604 meshes with the motor driving gear 603. By the operation of the motor 602, the motor driving gear 603 is driven to rotate. The motor driving gear 603 drives the meshing winding shaft driven gear 604 to rotate, and the winding shaft driven gear 604 drives the winding shaft 3 to rotate, realizing the winding of the copper wire.

[0025] In this embodiment, the wire clamping and cutting mechanism 4 includes a winding plate 401 fixedly sleeved on the winding shaft 3. On both sides of the winding shaft 3 on the winding plate 401, a pair of mounting seats 402 are symmetrically and fixedly connected. A pneumatic clamping jaw cylinder 403 is fixedly connected to the mounting seat 402. The output end of the pneumatic clamping jaw cylinder 403 is fixedly connected to a pneumatic clamping jaw 404. The pneumatic clamping jaw 404 has a rotating function. One end of the copper tube 5 extends to the position of the pneumatic clamping jaw 404. During use, the copper wire on the wire-releasing copper coil 8 passes through the copper tube 5 and is placed at the pneumatic clamping jaw cylinder 403. The pneumatic clamping jaw cylinder 403 is driven to extend the pneumatic clamping jaw 404 to clamp and fix the copper wire, so as to realize the fixation of the copper wire, which helps the copper wire to cooperate with the winding shaft 3 for winding and makes the copper wire winding tight.

[0026] In this embodiment, a pneumatic scissors 405 is installed on one side of the mounting seat 402 close to the winding shaft 3. After the copper wire winding is completed, the copper wire at this position is cut by the pneumatic scissors 405 to form a wound coil.

[0027] In this embodiment, the flattening mechanism 9 includes a flattening mechanism fixing frame 901 fixedly connected to the bottom plate 1. A flattening mechanism cylinder 902 is installed on one side of the flattening mechanism fixing frame 901 close to the winding shaft 3. The output end of the flattening mechanism cylinder 902 is fixedly connected to a flattening block 903. After the copper wire winding on the winding shaft 3 is completed, the flattening mechanism cylinder 902 is driven to move the flattening block 903 close to the wound coil on the winding shaft 3, so that the flattening block 903 contacts the two leads of the coil, flattens the leads, and makes the leads perpendicular to the winding shaft, facilitating subsequent spot welding with the chip.

[0028] In this embodiment, a stripping mechanism 10 is installed between the winding plate 401 and the winding shaft 3. The stripping mechanism 10 includes a pushing cylinder installed on the winding plate 401 and a stripping block slidably sleeved on the winding shaft 3. The output end of the pushing cylinder is fixedly connected to the stripping block. By the operation of the pushing cylinder, the stripping block is pushed to move axially along the winding shaft 3, so as to push the finished coil off the winding shaft 3, facilitating the rapid stripping process of the coil and contributing to subsequent production and processing.

[0029] In this embodiment, a set of wire-releasing copper coils 8, copper wire tubes 5, mounting seats 402, pneumatic gripper cylinders 403, pneumatic grippers 404, and pneumatic scissors 405 form a coil forming structure. This enables the present application to have two coil forming structures, allowing the simultaneous winding of two coils without interference, thus greatly improving production efficiency.

[0030] The control method of this utility model is controlled by the controller of the copper wire vertical winding device. The control program of the controller can be realized by simple programming of those skilled in the art. Therefore, the control method and circuit connection of this utility model will not be explained in detail.

[0031] Implementation scheme: During use, install two wire-releasing copper coils 8 on the wire-releasing copper coil fixing frame 7, and draw the two insulated copper wires on the two wire-releasing copper coils 8 respectively through the two wire-releasing copper coils 8 on the winding shaft fixing plate 2 to the winding shaft 3. Click the device operation page to drive the pneumatic gripper cylinder 403 to drive the pneumatic gripper 404 to extend, and the two pneumatic grippers 404 respectively clamp the two insulated copper wires.

[0032] The motor 602 operates to drive the motor driving gear 603 to rotate. The motor driving gear 603 drives the winding shaft driven gear 604 meshing with it to rotate, and the winding shaft driven gear 604 drives the winding shaft 3 to rotate, realizing the winding of the copper wire.

[0033] Start the device switch and click the start button. The motor 602 operates to drive the motor driving gear 603 to rotate. The motor driving gear 603 drives the winding shaft driven gear 604 meshing with it to rotate, and the winding shaft driven gear 604 drives the winding shaft 3 to rotate. The winding shaft 3 starts to rotate and wind. When the winding shaft 3 rotates, it winds the wire according to the set number of rotation circles and telescopic distance in the program. During wire winding, the position of the pneumatic gripper 404 can be adjusted by the pneumatic gripper cylinder 403 to adjust the winding position of the copper wire on the winding shaft 3 for wire winding.

[0034] After the wire winding is completed, the motor 602 stops working. The pneumatic gripper 404 rotates 90° to flip the copper wire, releases the coil lead wire and rotates and retracts to its original position. The winding shaft 3 rotates to align the pneumatic gripper 404 with the other lead wire of the coil, extends the pneumatic grippers 404 on both sides, and clamps the copper wire. Repeat the action of flipping the copper wire. The pneumatic scissors 405 on both sides extend to cut the copper wire and then retract to their original positions. The pneumatic gripper 404 rotates and retracts to its original position.

[0035] The flattening mechanism cylinder 902 drives the flattening block 903 to move closer to the wound coil on the winding shaft 3, so that the flattening block 903 contacts the two leads of the coil, flattens the leads, makes the leads perpendicular to the winding shaft, which is convenient for subsequent spot welding with the wafer. After flattening, the flattening mechanism cylinder 902 drives the flattening block 903 to reset, and the pushing cylinder works to push the stripping block to move axially along the winding shaft 3, pushing the finished coil off the winding shaft 3 to the middle turntable and returning to the original position to complete winding;

[0036] Repeat the above operations;

[0037] After the operation is completed, turn off the machine switch.
