Description

Technical Field

[0001] This utility model belongs to the field of coil lead cutting technology, and in particular relates to a punching mechanism that can freely adjust the lead length. Background Technology

[0002] Coil winding machine: As the name suggests, a winding machine is a machine that winds a wire-like object onto a specific workpiece. Most electrical products require inductor coils made of enameled copper wire (or simply enameled wire), thus necessitating the use of a winding machine. The working process of an existing coil winding machine mainly includes the following steps: 1. Preparation Stage: Wind the wire or cable from the needle onto the spool as required. First, install the wire or cable onto the spool, then guide it onto the spool using the needle. This step ensures the wire or cable starts in the correct position, preparing it for subsequent winding.

[0003] 2. Winding Stage: The winding head is rotated and moved by a servo system to achieve precise coil winding. The servo system precisely controls the movement of the winding head, ensuring the winding accuracy and consistency of the coil. This step is one of the core functions of the coil winding machine and directly affects the quality of the final product.

[0004] 3. Completion Stage: When the coil reaches the predetermined number of turns, the control system will send a signal to stop winding. Subsequently, the take-up system will neatly collect the wound coil. When the coil reaches the predetermined number of turns, the control system will send a stop signal.

[0005] 4. Subsequently, the cutting system cuts the wires or cables, separating them from those fixed to the spool and the needle. The take-up system neatly collects the wound coils, ready for further processing or storage. This coil-winding process is repeated.

[0006] In the above process, at the beginning of the winding, the wire or cable needs to be wound onto the spool for positioning. After the winding is completed, the wire or cable needs to be cut with a cutting system before the take-up system can be used to cut the coil. This process involves many actions, which affects the processing efficiency. In addition, each time the wire or cable is wound onto the spool for positioning, deviations are prone to occur, affecting the processing accuracy.

[0007] Referring to a coil lead tangling clamping mechanism disclosed in Chinese Patent Publication No. CN223260463U, this design includes a base, a lead fixing seat, a tangling post, and a fixing post. The lead fixing seat is located at the upper end of the base, which includes a base plate and a mounting ring, with the mounting ring mounted on the base plate. A fixing groove is provided on the outer side of the lead fixing seat, dividing it into a wiring section and a mounting section. The mounting section is located on one side of the base, and a wiring port is provided on the wiring section, penetrating the wiring section and communicating with the fixing groove. The lead fixing seat also has a fixing hole and a tangling hole, which are perpendicular to the wiring section. The tangling hole penetrates the mounting section, the fixing groove, and the wiring section, while the fixing hole penetrates the mounting section and the fixing groove. The tangling post is located on the mounting ring and below the tangling hole, for passing through the tangling hole. The fixing post is located on the mounting ring and below the fixing hole, for passing through the fixing hole. After the base is fixed, the lead wire fixing seat is set on the mounting ring. At this time, the tangent passes through the mounting part, fixing groove and wiring part along the tangent hole, and the fixing post passes through the mounting part and fixing groove along the fixing hole and abuts against the wiring part. When the needle drives the wire from the wiring port into the fixing groove, the base and lead wire fixing seat move away from each other. The tangent moves back into the mounting part along the direction of the tangent hole, and the fixing post moves away from the mounting part along the direction of the fixing hole. The needle drives the wire to wrap around the fixing groove and pass through the tangent hole and fixing hole in sequence. Then it is pulled out from the other side of the wiring port. After the wire passes through the fixing hole, the base and lead wire fixing seat move closer to each other. The tangent and tangent hole cooperate to cut the wire. The fixing post and fixing hole cooperate to fix the position of the wire so that the wire abuts against the bottom of the wiring part. One action completes the cutting and clamping of the lead wire, which can effectively improve the processing speed. The wire extending from the connector then winds the workpiece on the winding head. After winding, the needle drives the wire back from the connector into the fixed groove. This repeated action completes the cutting and positioning work during winding, effectively improving processing speed and accuracy. However, the length of the lead wire cut by the coil lead cutting clamping mechanism provided in this solution cannot be adjusted, thus it cannot cope with complex production situations.

[0028] In one embodiment of this utility model, reference is made to Figures 1-3As shown, a punching mechanism capable of freely adjusting the lead wire length is provided, including a lead wire fixing seat 100 and a cutting seat 200, which are arranged opposite to each other. A fixing groove 110 is provided on the outer side of the lead wire fixing seat 100, dividing it into a wiring portion 120 and a mounting portion 130. The mounting portion 130 is located on one side of the cutting seat 200. A wiring port 121 is provided on the wiring portion 120, which passes through the wiring portion 120 and communicates with the fixing groove 110. The lead wire fixing seat 100 also has a fixing hole 140 and a cutting hole 150, which are perpendicular to the wiring portion 120. The cutting hole 150 passes through the mounting portion 130, the fixing groove 110, and the wiring portion 120, while the fixing hole 140 passes through the mounting portion 130 and the fixing groove 110. The cutting base 200 is provided with a tangent post 210 and a fixing post 220. The tangent post 210 is used to pass through the tangent hole 150, and the fixing post 220 is used to pass through the fixing hole 140. It also includes an adjustment mechanism 300, which includes a mounting ring 310 and an adjusting wire 320. The mounting ring 310 is sleeved on the mounting part 130, and one end of the adjusting wire 320 is set on the mounting ring 310, and the other end extends to the wiring port 121. In this embodiment, the tangent post 210 passes through the mounting portion 130, the fixing groove 110, and the wiring portion 120 along the tangent hole 150, and the fixing post 220 passes through the mounting portion 130 and the fixing groove 110 along the fixing hole 140, abutting against the wiring portion 120. When the needle drives the wire from the wiring port 121 into the fixing groove 110, the cutting seat 200 and the lead wire fixing seat 100 move away from each other, the tangent post 210 moves away along the direction of the tangent hole 150 and retracts into the mounting portion 130, and the fixing post 220 moves away along the direction of the fixing hole 140 and retracts into the mounting portion 130. In step 0, the needle drives the wire to wind around the fixing groove 110 and pass through the cutting hole 150 and the fixing hole 140 in sequence. Then it is pulled out from the other side of the connection port 121 and abuts against the adjusting screw 320. After the wire passes through the fixing hole 140, the cutting seat 200 and the lead wire fixing seat 100 move closer to each other. The cutting post 210 and the cutting hole 150 cooperate to cut the wire. The fixing post 220 and the fixing hole 140 cooperate to fix the position of the wire so that the wire abuts against the bottom of the connection part 120. One action completes the cutting and clamping of the lead wire, which can effectively improve the processing speed. The wire extending from the connector 121 then winds the workpiece on the winding head. After winding, the needle drives the wire to enter the fixing groove 110 from the connector 121 again. This repeated action completes the cutting and positioning work during winding, which can effectively improve the processing speed and processing accuracy. The length of the lead wire can be adjusted by adjusting the position of the adjusting wire 320 at the connector 121 through the mounting ring 310 to meet different production requirements and make the processing more flexible.

[0029] Specifically, refer to Figures 1-3As shown, the adjusting wire 320 includes a support portion 321, a U-shaped portion 322, and a straight portion 323. One end of the U-shaped portion 322 is connected to the support portion 321, and the other end is connected to the straight portion 323. The other end of the support portion 321 is connected to the mounting ring 310. The straight portion 323 is parallel to the wiring portion 120. In this embodiment, the straight portion 323 is parallel to the wiring portion 120, making the lead wire more stable and preventing the lead wire from being scratched.

[0030] Specifically, refer to Figures 1-3 As shown, the mounting ring 310 is sleeved on the mounting part 130 and slidably connected to the mounting part 130. The side end of the mounting ring 310 has several threaded holes 311, which penetrate the mounting ring 310. Screws are connected to the threaded holes 311 and abut against the mounting part 130 to fix the mounting ring 310. In this embodiment, by rotating the screws in the threaded holes 311, the mounting ring 310 is loosened or tightened on the mounting part 130, which is used to adjust the position of the adjusting screw 320 at the terminal 121 to adjust the lead wire length.

[0031] Specifically, refer to Figures 1-3 As shown, the side of the cutting base 200 is provided with a mounting groove 230, which divides the cutting base 200 into a fixing part 240 and a connecting part 250. The connecting part 250 is located on one side of the mounting part 130. The connecting part 250 is provided with two locking interfaces 251, which are located below the tangent hole 150 and the fixing hole 140, respectively. The locking interfaces 251 pass through the wiring part 120 and communicate with the mounting groove 230. The openings of the locking interfaces 251 face outwards from the connecting part 250, and the two locking interfaces 251 are used to lock the fixing post 220 and the tangent post 210, respectively. In this embodiment, the tangent post 210 and the fixing post 220 are connected by the card interface 251. When the tangent post 210 and the fixing post 220 are damaged or need to be replaced, the tangent post 210 and the fixing post 220 can be removed from the open end of the card interface 251, making it convenient to replace the tangent post 210 and the fixing post 220.

[0032] Specifically, refer to Figures 1-3 As shown, the upper end of the tangent post 210 is provided with a cutter 211, and the lower end of the tangent post 210 is provided with a tangent recess 212. The height of the tangent recess 212 is equal to the height of the locking interface 251. The locking interface 251, located below the tangent hole 150, is used to fix the tangent recess 212. In this embodiment, the cutter 211 passes through the tangent hole 150 to cut the wire in the tangent hole 150. The height of the tangent recess 212 is equal to the height of the locking interface 251, so that the tangent post 210 will not slip after being installed in the locking interface 251, thus improving the success rate of cutting the wire.

[0033] Specifically, refer to Figures 1-3As shown, the upper end of the fixing post 220 is provided with a fixing head 221, and the lower end of the fixing post 220 is provided with a fixing recess 222. The height of the fixing recess 222 is higher than the height of the card interface 251, and the fixing recess 222 is slidably connected in the card interface 251 located below the fixing hole 140. The mounting groove 230 is also provided with an elastic member 223. One end of the elastic member 223 abuts against the fixing part 240, and the other end abuts against the bottom of the fixing post 220. In this embodiment, the fixing head 221 abuts against the bottom of the wiring part 120 to fix the wire. The height of the fixing recess 222 is higher than the height of the card interface 251, so that the fixing post 220 can slide in the vertical direction. The elastic member 223 plays a buffering role. When the contact force between the fixing head 221 and the bottom of the wiring part 120 is too large, the elastic member 223 is compressed, reducing the pressure on the wire between the fixing head 221 and the wiring part 120, and preventing the fixing head 221 from scratching or breaking the wire.

[0034] Specifically, refer to Figures 1-3 As shown, the bottom of the wiring part 120 is also provided with a positioning groove 122. The positioning groove 122 is located above the fixing hole 140 and is on the same center line as the fixing hole 140. The positioning groove 122 matches the fixing head 221. In this embodiment, the fixing head 221 fixes the wire in the positioning groove 122 to avoid the friction between the wire and the fixing head 2214 being too small, which would cause the wire to slip, thereby damaging the wire and affecting product quality.

[0035] Specifically, refer to Figures 1-3 As shown, the lead wire fixing base 100 has two connection ports 121, two fixing holes 140, and two tangent holes 150 mirror-imaged around its center line. The cutting base 200 has four card slots 251, each card slot 251 being mirror-imaged in pairs around the center line of the cutting base 200. In this embodiment, the lead wire fixing base 100 has two connection ports 121, two fixing holes 140, and two tangent holes 150 mirror-imaged around its center line. The cutting base 200 is provided with four card interfaces 251. Each card interface 251 is arranged in pairs around the center line of the cutting base 200. Due to the processing technology, the wire may pass through the fixing groove 110 clockwise or counterclockwise. Two connection ports 121, two fixing holes 140, two cutting holes 150 and four card interfaces 251 are provided to facilitate the adjustment of the cutting post 210 and the fixing post 220, so as to ensure that the wire passes through the cutting hole 150 first and then the fixing hole 140.

[0036] Specifically, refer to Figures 1-3As shown, it also includes two guide posts 400, which are mirror images of the tangent post 210 and the fixing post 220, respectively, around the center line of the cutting seat 200, and the guide posts 400 are snapped onto the snap-fit ​​interface 251. In this embodiment, the guide posts 400 serve a guiding function to prevent the cutting seat 200 and the lead wire fixing seat 100 from moving laterally relative to each other.
