[0002] Coil Winding Machine: As the name suggests, a coil winding machine is a machine that winds linear objects onto a specific workpiece. Most electrical products require enameled copper wire (enameled wire for short) to be wound into inductor coils, so a coil winding machine is needed. The working process of an existing coil winding machine mainly includes the following steps:

[0003] 1. Preparation: Wind the wire or cable from the needle onto the reel of the winding head as required. First, install the wire or cable on the spool, then use the needle to guide the wire or cable onto the reel of the winding head. This step ensures that the wire or cable starts in the correct position, preparing it for subsequent winding work.

[0004] 2. Winding Stage: The servo system controls the rotation and movement of the winding head to achieve precise coil winding. The servo system precisely controls the movement of the winding head, ensuring precise and consistent winding. This step is a core function of the coil winding machine and is directly related to the quality of the final product.

[0005] 3. Completion Phase: When the coil reaches the predetermined number of turns, the control system sends a signal to stop winding. The take-up system then neatly collects the wound coils. When the coil reaches the predetermined number of turns, the control system sends a stop signal.

[0006] 4. The cutting system then cuts the wire or cable, separating the wire or cable fixed on the spool and the wire or cable on the needle. The take-up system neatly collects the wound coils for further processing or storage. This coil winding process is repeated.

[0007] In the above process, the wire or cable needs to be wound on the bobbin for positioning at the beginning of winding, and after the wiring is completed, the wire or cable needs to be cut by the cutting system before the coil can be unloaded by the take-up system. During this process, there are many actions, which affects the processing efficiency. In addition, each time the wire or cable is wound on the bobbin for positioning, deviations are prone to occur, affecting the processing accuracy. Utility Model Content

[0009] In order to achieve the above-mentioned purpose, an embodiment of the present invention provides a coil lead tangent clamping mechanism, comprising a base, a lead fixing seat, a tangent column and a fixing column. The lead fixing seat is arranged at the upper end of the base, and the base includes a base plate and a mounting ring, and the mounting ring is arranged on the base plate. A fixing groove is provided on the outer side of the lead fixing seat, and the fixing groove separates the lead fixing seat into a wiring portion and a mounting portion. The mounting portion is arranged on one side of the base, and a wiring port is provided on the wiring portion, and the wiring port passes through the wiring portion and is connected to the fixing groove. The lead fixing seat is also provided with a fixing hole and a tangent hole, and the fixing hole and the tangent hole are perpendicular to the wiring portion, and the tangent hole passes through the mounting portion, the fixing groove and the wiring portion, and the fixing hole passes through the mounting portion and the fixing groove. The tangent column is arranged on the mounting ring and is located below the tangent hole, and is used to pass through the tangent hole. The fixing column is arranged on the mounting ring and is located below the fixing hole, and is used to pass through the fixing hole.

[0010] Furthermore, a mounting groove is provided on the side of the mounting ring, dividing it into a fixed portion and a connecting portion. The fixed portion is fixed to the base plate, while the connecting portion is located below the mounting portion. The connecting portion is provided with two snap-in connectors, located below the tangent hole and the fixing hole, respectively. The snap-in connectors extend through the wiring portion and communicate with the mounting groove. The snap-in connector openings face outward from the connecting portion and are used to engage the fixing post and the tangent post, respectively.

[0011] Furthermore, a cutter is provided at the upper end of the tangent column, and a tangent recess is provided at the lower end of the tangent column.

When the wire needle drives the wire from the wiring port into the fixing groove, the base and the lead fixing seat move away from each other, the tangent post moves back to the mounting portion along the tangent hole direction, and the fixing post moves away from the fixing hole direction and abuts against the wiring portion. The wire needle drives the wire to wrap around the fixing groove and pass through the tangent hole and the fixing hole in turn, and then pull out from the other side of the wiring port. After the wire enters the fixing hole, the base and the lead fixing seat approach each other, the tangent post and the tangent hole cooperate with each other to cut the wire, and the fixing post and the fixing hole cooperate with each other to fix the wire position so that the wire abuts the bottom end of the wiring portion. One action completes the tangent and clamping of the lead, which can effectively improve the processing speed.

After the winding is completed, the needle drives the wire from the wiring port into the fixed groove again. This repeated action completes the cutting and positioning work in the winding, which can effectively improve the processing speed and processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0026] In one embodiment of the present invention, reference Figures 1 to 3As shown, a coil lead tangent clamping mechanism is provided, comprising a base 100, a lead fixing base 200, a tangent post 300, and a fixing post 400. The lead fixing base 200 is disposed at the upper end of the base 100. The base 100 includes a bottom plate 110 and a mounting ring 120, which is disposed on the bottom plate 110. A fixing groove 210 is provided on the outer side of the lead fixing base 200. The fixing groove 210 divides the lead fixing base 200 into a wiring portion 220 and a mounting portion 230. The mounting portion 230 is disposed on one side of the base 100. The wiring portion 220 has a wiring port 221 defined therein. The wiring port 221 extends through the wiring portion 220 and communicates with the fixing groove 210. The lead holder 200 is further provided with a fixing hole 240 and a tangent hole 250. The fixing hole 240 and the tangent hole 250 are perpendicular to the wiring portion 220. The tangent hole 250 extends through the mounting portion 230, the fixing slot 210, and the wiring portion 220, while the fixing hole 240 extends through the mounting portion 230 and the fixing slot 210. A tangent post 300 is provided on the mounting ring 120 and below the tangent hole 250, for passing through the tangent hole 250. A fixing post 400 is provided on the mounting ring 120 and below the fixing hole 240, for passing through the fixing hole 240. In this embodiment, after the base 100 is fixed, the lead fixing seat 200 is set on the mounting ring 120. At this time, the tangent column 300 passes through the mounting portion 230, the fixing groove 210 and the wiring portion 220 along the tangent hole 250, and the fixing column 400 passes through the mounting portion 230 and the fixing groove 210 along the fixing hole 240, and abuts against the wiring portion 220. When the wire needle drives the wire from the wiring port 221 into the fixing groove 210, the base 100 and the lead fixing seat 200 move away from each other, the tangent column 300 moves back to the mounting portion 230 along the tangent hole 250, and the fixing column 400 The wire moves away from the fixing hole 240 and retreats to the mounting portion 230. The wire needle drives the wire to wind around the fixing groove 210 and pass through the tangent hole 250 and the fixing hole 240 in sequence, and then pulls it out from the other side of the wiring port 221. After the wire passes through the fixing hole 240, the base 100 and the lead fixing seat 200 approach each other, and the tangent post 300 cooperates with the tangent hole 250 to cut the wire. The fixing post 400 and the fixing hole 240 cooperate to fix the wire position so that the wire abuts the bottom end of the wiring portion 220. This action completes the tangent and clamping of the lead wire in one action, which can effectively improve the processing speed. The wire extending from the wiring port 221 is then wound around the workpiece on the winding head. After the winding is completed, the wire needle drives the wire from the wiring port 221 into the fixing groove 210 again. This repeated action completes the cutting and positioning work during the winding process, which can effectively improve the processing speed and processing accuracy.

[0027] More specifically, refer to Figures 1 to 3 As shown, when the winding is completed, the wire needle drives the wire from the wiring port 221 into the fixing groove 210 again, and the winding head moves backward to pull out the lead wire remaining in the fixing groove 210 to avoid affecting the cutting and fixing of the lead wire at the other end.

[0028] Specifically, refer to Figures 1 to 3 As shown, a mounting groove 121 is provided on the side of the mounting ring 120. The mounting groove 121 divides the mounting ring 120 into a fixed portion 122 and a connecting portion 123. The fixed portion 122 is fixed to the base plate 110, and the connecting portion 123 is located below the mounting portion 230. The connecting portion 123 is provided with two latching interfaces 124, which are located below the tangent hole 250 and the fixing hole 240, respectively. The latching interfaces 124 pass through the wiring portion 220 and communicate with the mounting groove 121. The openings of the latching interfaces 124 face outward from the connecting portion 123 and are used to latch onto the fixing column 400 and the tangent column 300, respectively. In this embodiment, the tangent column 300 and the fixed column 400 are connected by the card interface 124. When the tangent column 300 and the fixed column 400 are damaged or the specifications of the tangent column 300 and the fixed column 400 need to be replaced, it is only necessary to remove the tangent column 300 and the fixed column 400 from the open end of the card interface 124, so that the tangent column 300 and the fixed column 400 can be easily replaced.

[0029] Specifically, refer to Figures 1 to 3 As shown, a cutter 310 is provided at the upper end of the tangent post 300, and a tangent recess 320 is provided at the lower end. The height of the tangent recess 320 is equal to the height of the card interface 124. The card interface 124, located below the tangent hole 250, is used to secure the tangent recess 320. In this embodiment, the cutter 310 passes through the tangent hole 250 to cut the wire in the tangent hole 250. The height of the tangent recess 320 is equal to the height of the card interface 124. This prevents the tangent post 300 from slipping after being installed in the card interface 124, thereby improving the success rate of cutting the wire.

[0030] Specifically, refer to Figures 1 to 3 As shown, the upper end of the fixing post 400 is provided with a fixing head 410, and the lower end of the fixing post 400 is provided with a fixing recess 420. The height of the fixing recess 420 is higher than the height of the card interface 124, and the fixing recess 420 is slidably connected to the card interface 124 located below the fixing hole 240. An elastic member 430 is also provided on the mounting slot 121. One end of the elastic member 430 abuts the fixing portion 122, and the other end abuts the bottom of the fixing post 400. In this embodiment, the fixing head 410 abuts the bottom of the wiring portion 220 to secure the wires. The height of the fixing recess 420 is higher than the height of the card interface 124, allowing the fixing post 400 to slide vertically. The elastic member 430 acts as a buffer. When the abutment force between the fixing head 410 and the bottom of the wiring portion 220 is too great, the elastic member 430 is compressed, reducing the pressure on the wires between the fixing head 410 and the wiring portion 220, preventing the fixing head 410 from scratching or breaking the wires.

[0031] Specifically, refer to Figures 1 to 3As shown, the bottom of the wiring portion 220 is further provided with a positioning groove 222. The positioning groove 222 is located above the fixing hole 240 and is located on the same center line as the fixing hole 240. The positioning groove 222 matches the fixing head 410. In this embodiment, the fixing head 410 secures the wire in the positioning groove 222, preventing the friction between the wire and the fixing head 410 from being too low, causing the wire to slip, thereby damaging the wire and affecting product quality.

[0032] Specifically, refer to Figures 1 to 3 As shown, the lead wire holder 200 is provided with two wiring ports 221, two fixing holes 240, and two tangent holes 250, mirrored around its centerline. The base 100 is provided with four snap-in interfaces 124, each mirrored pair of each other around the centerline of the base 100. In this embodiment, the lead wire holder 200 is provided with two wiring ports 221, two fixing holes 240, and two tangent holes 250, mirrored around its centerline. Due to manufacturing process limitations, wires may be routed around the fixing slot 210 either clockwise or counterclockwise. The two wiring ports 221, two fixing holes 240, two tangent holes 250, and four snap-in interfaces 124 facilitate adjustment of the tangent post 300 and the fixing post 400, ensuring that the wires pass through the tangent holes 250 before the fixing holes 240.

[0033] Specifically, refer to Figures 1 to 3 As shown, two guide posts 500 are further included. The two guide posts 500 are arranged around the center line of the base 100 in a mirror-image manner with the tangent post 300 and the fixed post 400, and the guide posts 500 are snapped onto the card interface 124. In this embodiment, the guide posts 500 serve as guides to prevent the base 100 and the lead holder 200 from lateral movement relative to each other.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
