Description

Technical Field

[0001] This invention relates to the field of wire winding and packaging technology, specifically to a high-efficiency coil winding device for inductor production. Background Technology

[0002] Inductors play a crucial role in electronic devices, communication systems, and power equipment. With the rapid development of high-frequency electronic devices and the trend towards miniaturization, inductors have higher requirements for high-precision and high-efficiency production. Traditional inductor coil winding methods usually rely on manual or semi-automatic equipment, resulting in low production efficiency, unstable accuracy, and difficulty in meeting the needs of high-density, small-volume inductor products.

[0003] In the current inductor production process, workers need to fix one end of the copper coil to the magnetic core by welding or bonding, and then start the winding machine to wind the copper wire around the surface of the magnetic core. After the coil is wound, workers need to cut the copper wire to separate the copper coil from the wound magnetic core. During the operation, workers need to operate repeatedly inside the equipment. If the equipment is accidentally activated, it may cause the workers to be injured. At the same time, the repeated fixing and separating of the copper coil and the magnetic core during the production process is not conducive to the efficient winding work.

[0004] To address this, a high-efficiency coil winding device for inductor production is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency coil winding device for inductor production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency coil winding device for inductor production, comprising a winding machine body and a shaping component disposed on the winding machine body, the shaping component comprising a slide plate, a first round rod and a first clamping plate, the slide plate being symmetrically slidably connected to the interior of the winding machine body, the first round rod being rotatably connected to the top of the slide plate, a main turntable being fixedly connected to the top of the first round rod, a support frame being fixedly connected to the outer wall of the first round rod, and diagonal rods being symmetrically fixedly connected to the middle section of the upper surface of the support frame, the top of each diagonal rod being slidably connected to a first sliding rod, a first clamping plate being fixedly connected to the end of each first sliding rod away from the main turntable, and a first spring being fixedly connected between the first clamping plate and the diagonal rod, the first spring being sleeved on the outer wall of the first sliding rod.

Each extraction component includes a second round rod, a cylinder, and a second clamping plate. The second round rod is symmetrically slidably connected to the outer wall of the winding machine body. A second spring is fixedly connected between the second round rod and the winding machine body. A turntable is rotatably connected to the top of the second round rod. A third round rod is rotatably connected inside the second round rod. The cylinder is fixedly connected to the top of the third round rod. A lever is fixedly connected to the bottom of the outer wall of the third round rod. The lever is movable on the outer wall of the second round rod. A second slide rod is slidably connected to the outer wall of the second round rod and below the turntable. The second clamping plate is fixedly connected to the end of the second slide rod away from the second round rod. A slot is formed on the surface of the cylinder, which is adapted to the end of the second slide rod located inside the second round rod. A third spring is fixedly connected between the second clamping plate and the outer wall of the second round rod. The third spring is sleeved on the outer wall of the second slide rod. The side of the second clamping plate away from the second round rod is wavy. A lever is fixedly connected to the surface of the winding machine body.

[0008] Preferably, the second round rod is provided with a separation component, which includes a limiting chamber, a gear, and a cutter. The upper surface of the support is symmetrically fixedly connected with toothed plates. The outer wall of the second round rod is fixedly connected with the limiting chamber. A slider is slidably connected inside the limiting chamber. A lead screw is threaded inside the slider. The gear is fixedly connected to the end of the lead screw located outside the limiting chamber. The cutter is fixedly connected to the side of the slider away from the gear. The toothed plates and the gear mesh with each other.

[0009] Preferably, the winding machine body is provided with a drive device inside, a rotating wheel is rotatably connected to the winding machine body, a copper coil is provided on the inner wall of the rotating wheel, a magnetic core is placed between the main turntable and the slave turntable, a limit plate is fixedly connected to the top of the winding machine body, and dynamic sensors are provided on the opposite surfaces of the limit plate.

[0010] Preferably, the inner wall of the main turntable is provided with rubber protrusions, both ends of the first clamping plate near the magnetic core are set as arc surfaces, a motor is provided inside the sliding plate, the first round rod is driven and mounted on the motor, a controller is provided inside the winding machine body, and the motor is electrically connected to the dynamic sensor through the controller.

[0011] Preferably, the bottom of the second clamping plate near the copper coil is set as an arc surface. When the dial plate abuts against the stop block near the magnetic core, the second slide rod is not engaged with the cylinder. When the dial plate abuts against the stop block away from the magnetic core, the second slide rod is engaged with the groove of the cylinder.

[0012] Preferably, when the second slide bar is not engaged with the cylindrical slot, the adjacent surfaces of the two second clamping plates are tightly fitted together.

[0013] Preferably, the rotating wheel is provided with a buckle, and the rotating wheel is connected end to end by the buckle to form a ring.

[0014] Preferably, the outer wall of the second round rod is provided with a frame, and the support is limited and slidable within the frame of the second round rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. During the process of the first clamping plate pressing the inner wall of the magnetic core, the distance the first clamping plate is pushed to is different for magnetic cores of different diameters. Therefore, the contraction of the first clamping plate at different distances can be made to fit tightly against the inner wall of the magnetic core by the elastic force of the first spring. This allows the copper coil to bend under the pressing action of the first clamping plate after the magnetic core is placed inside the equipment. When the copper coil is wound on the outer wall of the magnetic core, the copper coil wound on the magnetic core is stable and does not slip, and the copper coil is evenly wound on the surface of the magnetic core.

[0016] 2. During use, the copper coil is always stretched to the side close to the magnetic core, eliminating the need for the operator to pull the copper coil outward and then wind it around the magnetic core. When the magnetic core is placed on the main turntable and pushed from the turntable into the equipment, the copper coil is squeezed by the first clamping plate, causing it to bend and conform to the inner wall of the magnetic core, thus fixing the copper coil to the magnetic core when it is wound around the magnetic core.

[0017] 3. The sliding block moves the two cutters closer together, which cuts the copper coil. This allows the copper coil to be automatically cut when the first rod is pulled out, and the copper coil is no longer wrapped with the magnetic core, making it easier for the staff to remove the inductor after it has been wound.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] Embodiments of the present invention Please see Figures 1 to 5A high-efficiency coil winding device for inductor production includes a winding machine body 1 and a shaping assembly 11 disposed on the winding machine body 1. The shaping assembly 11 includes a slide plate 111, a first round rod 112, and a first clamping plate 117. The slide plate 111 is symmetrically slidably connected to the inside of the winding machine body 1. The first round rod 112 is rotatably connected to the top of the slide plate 111. The top of the first round rod 112 is fixedly connected to a main turntable 113. A support frame 114 is fixedly connected to the outer wall of the first round rod 112. Inclined rods 115 are symmetrically fixedly connected to the middle section of the upper surface of the support frame 114. The top of each inclined rod 115 is slidably connected to a first sliding rod 116. The end of each first sliding rod 116 away from the main turntable 113 is fixedly connected to a first clamping plate 117. A first spring 118 is fixedly connected between the first clamping plate 117 and the inclined rod 115. The first spring 118 is sleeved on the first... The outer wall of a slide bar 116; a drive device 2 is installed inside the winding machine body 1; a rotating wheel 3 is rotatably connected to the winding machine body 1; a copper coil 4 is installed on the inner wall of the rotating wheel 3; a magnetic core 5 is placed between the main turntable 113 and the secondary turntable 128; a limit plate 6 is fixedly connected to the top of the winding machine body 1; dynamic sensors are installed on the opposite sides of the limit plate 6; a buckle is installed on the rotating wheel 3; the rotating wheel 3 is connected end to end by the buckle to form a ring; the outer wall of the rotating wheel 3 is provided with tooth grooves; the drive device 2 drives the rotating wheel 3 to rotate by meshing with the tooth grooves on the outer wall of the rotating wheel 3; rubber protrusions are provided on the inner wall of the main turntable 113; both ends of the first clamping plate 117 near the magnetic core 5 are set as arc surfaces; a motor is installed inside the slide plate 111; the first round rod 112 is driven and installed on the motor; a controller is installed inside the winding machine body 1; the motor is electrically connected to the dynamic sensor through the controller.

[0022] In practical applications, the embodiments of the present invention are as follows: In use, the operator pulls the first round rod 112 to slide the slide plate 111 outward from the inside of the winding machine body 1. As the first round rod 112 moves outward, the distance between the main turntable 113 and the slave turntable 128 increases. Then, the operator places the magnetic core 5 between the main turntable 113 and the slave turntable 128 and pushes the first round rod 112 towards the side closer to the magnetic core 5, so that the main turntable 113 and the slave turntable 128 limit the magnetic core 5. The movement of the first round rod 112 causes the support frame 114 to move together. The movement of the support frame 114 causes the first clamping plate 117 to move towards the inner wall of the magnetic core 5. During the movement, the first clamping plate 117 squeezes the straightened copper coil 4. The copper coil 4 is bent by the pressure of the first clamping plate 117, causing the extended end of the copper coil 4 to adhere to the inner wall of the magnetic core 5. During the process of the first clamping plate 117 pressing the inner wall of the magnetic core 5, the distance that the first clamping plate 117 is pushed by the magnetic core 5 with different diameters is different. Therefore, the contraction of the first clamping plate 117 at different distances can be made to adhere tightly to the inner wall of the magnetic core 5 by the elastic force of the first spring 118. Thus, after the magnetic core 5 is placed inside the equipment, the copper coil 4 can be bent under the pressure of the first clamping plate 117. When the copper coil 4 is wound on the outer wall of the magnetic core 5, the copper coil 4 wound on the magnetic core 5 is stable and does not slip, so that the copper coil 4 is evenly wound on the surface of the magnetic core 5.

[0023] Subsequently, the staff started the equipment, causing the drive device 2 to drive the rotating wheel 3 to start rotating. The rotation of the rotating wheel 3 caused the copper coil 4 to rotate inside it. During the rotation of the copper coil 4, since the magnetic core 5 is stationary, the copper coil 4 moves in a circular motion from the outer wall to the inner wall of the magnetic core 5. During the rotation of the copper coil 4, the stretched copper wire will rotate around the magnetic core 5 and wrap around the surface of the magnetic core 5. During the rotation of the copper coil 4, the stretched copper wire will pass through the limiting plate 6, which adjusts the angle of the copper wire winding. After the dynamic sensor inside the limiting plate 6 senses the passage of the copper wire, it will drive the motor through the controller inside the winding machine body 1, thereby causing the first round rod 112 and the main rotating disk 113 to rotate and drive the magnetic core 5 to rotate, so that the copper coil 4 can be evenly wound on the outer wall of the magnetic core 5.

[0024] Please see Figure 1 , Figure 6 and Figure 7The winding machine body 1 has symmetrically arranged extraction components 12 on its left and right sides. Each extraction component 12 includes a second round rod 121, a cylinder 124, and a second clamping plate 126. The second round rod 121 is symmetrically slidably connected to the outer wall of the winding machine body 1. A second spring 122 is fixedly connected between the second round rod 121 and the winding machine body 1. A turntable 128 is rotatably connected to the top of the second round rod 121. A third round rod 123 is rotatably connected inside the second round rod 121. The cylinder 124 is fixedly connected to the top of the third round rod 123. A lever 129 is fixedly connected to the bottom of the outer wall of the third round rod 123. The lever 129 is movable on the outer wall of the second round rod 121. A second sliding rod 125 is slidably connected to the outer wall of the second round rod 121 and located below the turntable 128. The second clamping plate 126 is fixedly connected to the end of the second sliding rod 125 away from the second round rod 121. A slot is formed on the surface of the cylinder 124, and the slot is connected to the second round rod 121. The second slide bar 125 is fitted to one end inside the second round bar 121. A third spring 127 is fixedly connected between the second clamping plate 126 and the outer wall of the second round bar 121. The third spring 127 is sleeved on the outer wall of the second slide bar 125. The side of the second clamping plate 126 away from the second round bar 121 is wavy. A dial plate 129 is fixedly connected to the surface of the winding machine body 1. The bottom of the second clamping plate 126 near the copper coil 4 is set as an arc surface. The dial plate 129 and the side of the second clamping plate 126 near the copper coil 4 are connected as an arc surface. When the stop 1210 on the side near the magnetic core 5 is in contact, the second slide rod 125 is not engaged with the cylinder 124. When the lever 129 is in contact with the stop 1210 on the side away from the magnetic core 5, the second slide rod 125 is engaged with the slot of the cylinder 124. When the second slide rod 125 is not engaged with the slot of the cylinder 124, the adjacent surfaces of the two second clamping plates 126 are tightly fitted. The outer wall of the second round rod 121 is provided with a frame, and the support 114 is limited to slide within the frame of the second round rod 121.

[0025] In practical applications, the embodiments of the present invention are as follows: When the operator prepares to use the equipment for coil winding, the operator first needs to slide the slide plate 111 out of the winding machine body 1 to increase the distance between the main turntable 113 and the secondary turntable 128. As the slide plate 111 moves, the first round rod 112 and the support frame 114 move together. The movement of the support frame 114 causes the toothed plate 131 on its upper surface to move as well. After the toothed plate 131 moves, it no longer compresses the second round rod 121 through the frame on the outer wall of the second round rod 121. At this time, the second spring 122 recovers its elasticity and pushes the second round rod 121 towards the first round rod 112. Since the second slide rod 125 is not engaged in the slot of the cylinder 124, the second clamping plate... 126 will stretch the copper coil 4 towards the first round rod 112 by clamping the copper wire of the copper coil 4. When the dial plate 129 comes into contact with the stop block 1210 on the side near the first round rod 112, the dial plate 129 is pushed by the stop block 1210, causing the third round rod 123 to rotate inside the second round rod 121. The rotation of the third round rod 123 drives the cylinder 124 to rotate together. After the cylinder 124 rotates, the orientation of the slot on its surface changes. The second slide rod 125 engages with the slot of the cylinder 124, so that the two second clamping plates 126 are relatively far apart and no longer squeeze the stretched copper coil 4, so that the two second clamping plates 126 cannot drive the copper coil 4. After the distance between the main turntable 113 and the secondary turntable 128 increases, the operator inserts the magnetic core 5 and pushes the slide plate 111 back into the winding machine body 1. At this time, the support frame 114 pushes the second round rod 121 to slide through the toothed plate 131. The lever 129 inside the second round rod 121 no longer squeezes the copper coil 4 through the second clamping plate 126 because of the rotation. Therefore, the second clamping plate 126 will only slide against the outer wall of the copper coil 4. Thus, during the operation, the copper coil 4 can always be stretched to the side close to the magnetic core 5. The operator does not need to pull the copper coil 4 outward and then wind it around the magnetic core 5. When the magnetic core 5 is placed on the main turntable 113 and the secondary turntable 128 and pushed into the equipment, the copper coil 4 is squeezed by the first clamping plate 117. The copper coil 4 bends and bends against the inner wall of the magnetic core 5, thus fixing the copper coil 4 and the magnetic core 5 when the copper coil 4 is wound around the magnetic core 5.

[0026] Please see Figures 1 to 3 , Figure 8 and Figure 9A separation assembly 13 is provided on the second round rod 121. The separation assembly 13 includes a limiting chamber 132, a gear 133, and a cutter 136. A toothed plate 131 is symmetrically fixedly connected to the upper surface of the support frame 114. The limiting chamber 132 is fixedly connected to the outer wall of the second round rod 121. A slider 135 is slidably connected inside the limiting chamber 132. A lead screw 134 is threadedly connected inside the slider 135. The gear 133 is fixedly connected to one end of the lead screw 134 located outside the limiting chamber 132. The cutter 136 is fixedly connected to the side of the slider 135 away from the gear 133. The toothed plate 131 and the gear 133 mesh with each other.

[0027] In practical applications, the embodiments of the present invention are as follows: After the copper coil 4 is wound around the magnetic core 5, the worker pulls the first round rod 112 out of the equipment. The movement of the first round rod 112 drives the support frame 114 and the toothed plate 131. When the toothed plate 131 moves laterally, it drives the gear 133 meshing with it to rotate. The rotation of the gear 133 drives the lead screw 134 to rotate together. During the rotation of the lead screw 134, the slider 135 connected to it by threads will slide inside the limiting chamber 132. The sliding of the slider 135 drives the two cutters 136 to move closer together. The closer proximity of the cutters 136 will cut the copper coil 4, so that the copper coil 4 can be automatically cut when the first round rod 112 is pulled out. The copper coil 4 is no longer wound with the magnetic core 5, which makes it easier for the worker to take it out after the inductor is wound.
