Description

Technical Field

[0001] The present invention relates to enameled wire manufacturing equipment, and more particularly to a fully automatic flat wire take-up machine for flat wire manufacturing. Background Art

[0002] An enameled wire is composed of an internal conductor and a coating that wraps the conductor. After the enameled wire undergoes processes such as annealing, painting, baking, and cooling, a take-up machine is required to arrange the baked enameled wire on a spool. In the take-up machine, the enameled wire passes through a wire arranging guide wheel and cooperates with a rotating spool. The spool is fixed in the take-up machine, and the rotation of the take-up machine drives the spool to rotate, thereby winding the enameled wire led out by the wire arranging guide wheel around the spool.

[0003] Most of the existing take-up machines are used for winding enameled wires with a circular cross-section. For the winding of flat wires, simple winding equipment and manual operation are basically used, and the degree of automation is very low.

[0004] Based on the low degree of automation of flat wire take-up, the applicant of this case previously proposed a technical solution for a fully automatic flat wire take-up machine with the publication number CN110844701A, which realized the automatic take-up of flat wires. However, the applicant believes that after long-term use, it is found that there are still some deficiencies in this technical solution, mainly manifested in: First, due to the certain width of the flat wire, there is a possibility of deflection or even flipping of the flat wire during continuous transportation before winding onto the spool, and the flat wire on the spool after winding is uneven, and there is a situation of squeezing the flat wire. Especially when switching between an empty spool and a full spool, the smoothness of the flat wire guiding is particularly important; Second, during winding, the tightness between the flat wire and the spool or between adjacent layers of the flat wire needs to be further improved; Third, on the spool, the starting section of the flat wire does not fit well with the spool. Then, during winding, every time it reaches the position of the starting section of the flat wire, it will protrude more than other positions, resulting in an uneven situation; Fourth, on the spool, when the flat wire is wound to the root at both ends of the spool, since it needs to change direction, there is a situation of looseness and unevenness; Fifth, currently, according to the cutting principle of round wires, the pulling force of the rotating spool on the wire head contacts the edge of the blade to achieve wire breaking. However, for flat wires with a larger thickness or width, manual wire breaking is required. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a fully automatic flat wire take-up machine that can orderly guide the wire before winding and can tightly press it in real time during winding. The starting section position of the flat wire winding is reasonable, the wire is tightened and level when reaching the edge during take-up, and the cutting is convenient after spool change.

[0006] According to one aspect of the present invention, there is provided a fully automatic flat wire take-up machine, which includes a frame, a wire arranging mechanism, and a take-up mechanism. The wire arranging mechanism is arranged on the frame, wherein:

[0007] The wire take-up mechanism includes a rotatable turntable, a turntable shaft connected to the turntable, and two rotatable wire take-up shafts symmetrically installed on the turntable with respect to the turntable shaft on the left and right. The turntable is located at the front side of the frame. A turntable bearing seat frame is sleeved on the turntable shaft, and the turntable bearing seat frame is arranged to be movable back and forth with respect to the wire arranging mechanism. The front end of the wire take-up shaft is connected with a wire take-up connecting shaft. The wire take-up connecting shaft is horizontally arranged with respect to the horizontal plane. The wire take-up connecting shaft is for installing a coil. An inlet groove is provided on the end face of the coil close to the turntable.

[0008] The wire arranging mechanism includes a guide wheel and a guide nozzle. The left and right sides of the turntable shaft are respectively called the full-coil working position and the wire take-up working position. The guide nozzle is located on the side where the wire take-up working position is located. A guiding groove for guiding the flat wire during transportation is provided at the lower part of the guide nozzle. The upper part of the guide nozzle is rotatably installed on the frame.

[0009] During wire take-up, the flat wire is guided by the guide wheel and the guiding groove and then wound on the coil. The starting section of the flat wire is located in the inlet groove. The coil moves back and forth with the turntable bearing seat frame. As the flat wire wound on the coil thickens, the lower part of the guide nozzle gradually retreats.

[0010] Thus, the starting section of the flat wire is pressed on the inlet groove. During the continuous transportation of the flat wire, after being led down by the guide wheel, it will pass through the guiding groove of the guide nozzle and reach the coil. During the wire take-up process, the installation position of the guide nozzle remains unchanged. The coil rotates and moves back and forth with respect to the guide nozzle to cooperate with the coil during wire take-up, so that the flat wire is evenly arranged on the coil. When the flat wire is wound on the coil, the guide nozzle always adheres to the surface of the coil. As the number of layers of the flat wire wound on the coil gradually increases, the front end of the guide nozzle is pushed to gradually retreat. Therefore, the position of the starting section of the flat wire is set reasonably, ensuring that the starting section of the flat wire fits with the coil to avoid the situation of protruding during winding. The guide nozzle controls the guiding of the flat wire in real time and ensures the tightness during winding.

[0011] In some embodiments, the flat wire full-automatic wire take-up machine further includes a wire pressing mechanism. The wire pressing mechanism is located on the side where the wire take-up working position is located. The wire pressing mechanism includes an outer pressing wheel, an inner pressing wheel, and a pressing wheel fixing seat. The pressing wheel fixing seat is installed on the frame. A pressing wheel sliding table movable with respect to the pressing wheel fixing seat is provided on one side of the pressing wheel fixing seat close to the guide nozzle. The pressing wheel sliding table is provided with a horizontally arranged wire pressing shaft rod. Two wire pressing arms are hinged to the wire pressing shaft rod. The outer pressing wheel and the inner pressing wheel are respectively installed at the front ends of the two wire pressing arms. Two wire pressing cylinders are hinged to the two wire pressing arms. The pressing wheel sliding table is connected with a cylinder mounting plate. The other end of the wire pressing cylinder is hinged to the cylinder mounting plate.

[0012] When wire take-up reaches the roots at both ends of the coil, the wire pressing cylinder drives the wire pressing arms, so that the outer pressing wheel and the inner pressing wheel respectively press the flat wire wound on the roots at both ends of the coil.

[0013] Therefore, a wire pressing mechanism is installed at the wire take-up working position. When the flat wire is wound to the roots at both ends of the coil at each layer, the corresponding wire pressing cylinder extends, the wire pressing arm rotates around the wire pressing shaft rod, and the outer pressure wheel or the inner pressure wheel presses against the flat wire being wound on the coil, so that the flat wire can be tightly wound at the roots of the coil. During the commutation and wire laying, the flat wire can be carried out in an orderly manner, ensuring the flatness after the wire is taken up at the roots at both ends of the coil and ensuring that the wire is taken up in place at the roots at both ends of the coil.

[0014] In some embodiments, both the outer pressure wheel and the inner pressure wheel are made of nylon wheels, and the end faces of the outer pressure wheel and the inner pressure wheel away from the wire pressing arm are both set to be stepped. Therefore, using nylon wheels is beneficial to protecting the surface of the flat wire. When the flat wire is wound to the roots of the coil and commutes, there is an extra layer at the position close to the roots of the coil. Through the stepped outer pressure wheel and inner pressure wheel, it can be ensured that the tightness between the flat wire covered after commutation and the upper layer of flat wire is good, and the surface of the flat wire is avoided from being over-pressed.

[0015] In some embodiments, trays are provided on both sets of wire take-up shafts, the coils are installed on the trays, wire catchers are provided on the edges of the trays, wire blocking rods are provided beside the trays, the wire blocking rods are fixed to the turntable, wire blocking rollers are provided on the side of the wire blocking rods away from the trays, and a cutting mechanism and a blocking rod are provided between the wire blocking roller and the side of the tray without the wire blocking rod;

[0016] When changing the coil, the turntable rotates, the full coil after wire take-up rotates to the full-coil working position, the empty coil to be wire-taken rotates to the wire take-up working position, the flat wire is pulled to the lower part of the wire blocking roller beside the full coil, the blocking rod is pressed down, the flat wire is pressed into the guiding groove of the empty coil, after the wire catcher at the wire take-up working position catches the wire, the flat wire is cut in the cutting mechanism.

[0017] Therefore, during wire take-up, the coil rotates clockwise. Before changing the coil, the empty coil is pre-installed on the wire take-up connecting shaft at the full-coil working position. The turntable rotates clockwise to adjust the positions of the full coil and the empty coil. The full coil rotates to the full-coil working position, and the empty coil rotates to the wire take-up working position. At the same time, the continuously conveyed flat wire is pulled to the full-coil working position along with the full coil. The flat wire bypasses the lower part of the wire blocking roller beside the full coil (i.e., the wire blocking roller under the turntable). The wire blocking rod cylinder is in the extended state, the blocking rod is above the flat wire and the flat wire is outside the cutting mechanism. Then, the wire blocking rod cylinder drives the blocking rod to press down the flat wire, and the flat wire is pressed into the guiding groove of the empty coil. The empty coil and the tray rotate, so that the wire catcher at the wire take-up working position hooks the flat wire. After the wire catcher hooks the flat wire, it continues to rotate, and the flat wire enters the cutting mechanism to complete the cutting.

[0018] In some embodiments, the cutting mechanism includes a tool holder, a cutting cylinder, and a cutting blade plate. The tool holder is fixed with tool side plates, and the cutting blade plate is rotatably installed on the tool side plates. The rear end of the cutting blade plate is hinged to the piston rod of the cutting cylinder. The cutting cylinder is installed on the tool holder. A cutting edge is provided on the front side of the tool side plates. A cutting edge opening is formed between the front part of the cutting blade plate and the cutting edge. The cutting cylinder drives the front end of the cutting blade plate to press down, and the cutting edge opening closes to cut the flat wire. Thus, when the flat wire reaches the cutting edge opening, the cutting cylinder extends to drive the rear end of the cutting blade plate to lift upward. The cutting blade plate rotates, the front end of the cutting blade plate presses downward, and the cutting edge opening closes to cut the flat wire. By applying an external force through the cutting cylinder to cut the flat wire, the acting force during cutting is increased, which is more reliable compared to the traditional method of pulling and hitting the cutting edge to break the wire, and this structure is also suitable for flat wires with relatively large sizes.

[0019] In some embodiments, a guide plate is provided on one side of the cutting blade plate. The guide plate is installed on the tool holder, and the bottom of the front end of the guide plate is inclined. Thus, after the wire-catching device rotates after hooking the wire, it pushes the flat wire under the guide plate and smoothly guides it under the cutting blade plate along the inclined side of the front end of the guide plate, ensuring that the flat wire can accurately reach the position of the cutting edge opening.

[0020] In some embodiments, the cutting edge opening formed between the cutting blade plate and the cutting edge is an inclined cutting edge opening, and the cutting edge opening is gradually inclined upward from the front end of the cutting blade plate backward. The cutting edge is a replaceable cutting edge. Thus, if the cutting edge is worn, it can be replaced to reduce costs. The inclined cutting edge opening can cause the flat wire to flip, so that the force required for cutting can be reduced, which is beneficial for cutting.

[0021] In some embodiments, the tool holder is provided with a travel switch. The travel switch is provided with a contact rod, and the contact rod is upward and located between the guide plate and the cutting blade plate. Thus, before the flat wire is brought into the cutting mechanism by the wire-catching device, the flat wire is perpendicular to the turntable. When it contacts the front inclined surfaces of the guide plate and the cutting blade plate, it gradually tilts. Then, before the flat wire enters the cutting edge opening from the guide plate, it first touches the contact rod. The flat wire pushes the contact rod, and the contact rod rotates backward. As the contact rod rotates, the flat wire flips along the inclined cutting edge opening. After the contact rod rotates in place, it triggers the cutting cylinder to start.

[0022] In some embodiments, the full-automatic flat wire rewinder further includes a pressing mechanism. The pressing mechanism is located on the side where the full-disk working position is located. The pressing mechanism includes a pressing wheel and a pressing cylinder. A horizontally arranged pressing shaft rod is provided on the front side of the turntable frame. The pressing shaft rod is hinged with a pressing arm. The pressing wheel is installed at the front end of the pressing arm. The machine frame is provided with a pressing fixed seat. The two ends of the pressing cylinder are respectively hinged with the pressing arm and the pressing fixed seat. Thus, when the rotation speed of the full-disk tool decreases and the full-disk tool rotates to the full-disk working position, the pressing cylinder extends, the pressing arm rotates around the pressing shaft rod, and the pressing wheel presses against the wire wound on the surface of the full-disk tool, which can prevent the wire tail of the flat wire from being out of control and causing the wound flat wire to become loose after the flat wire is cut.

[0023] In some embodiments, a sliding seat is connected to the bottom of the turntable bearing seat frame. The machine frame is provided with a bottom plate. The sliding seat is installed on the bottom plate through a linear guide rail slider assembly. The bottom plate is provided with a wire take-up displacement motor. The sliding seat is connected with a lead screw nut assembly. The wire take-up displacement motor acts on the lead screw nut assembly to drive the sliding seat to move back and forth. Thus, during the wire take-up process, the installation positions of the guide wheel and the guide nozzle remain unchanged. In this way, before the flat wire reaches the coiling tool for wire take-up, it is not easy to deflect or flip. To prevent the flat wire on the coiling tool from being pushed to one place, the wire take-up displacement motor is used to drive the lead screw nut assembly to move the sliding seat back and forth, thereby realizing the forward and backward movement of the coiling tool.

[0024] In some embodiments, the flat wire full-automatic wire take-up machine further includes a traction mechanism. The traction mechanism includes an inner guide wheel, an outer guide wheel, a constant-speed wheel, and a tensioning assembly. The inner guide wheel and the outer guide wheel are installed on the top of the machine frame. The outer guide wheel is aligned with the guide wheel. The constant-speed wheel is rotatably installed on the machine frame. The constant-speed wheel is connected with a traction motor. The tensioning assembly includes a pulley assembly located on one side of the constant-speed wheel and a belt wound around the pulley assembly. The belt covers an arc edge of the constant-speed wheel. The inner guide wheel is located obliquely above the constant-speed wheel. One of the pulleys of the pulley assembly is provided with an adjustable structure to adjust the belt tension. Thus, before the flat wire enters the outer guide wheel, it first bypasses the constant-speed wheel. When passing through the surface of the constant-speed wheel, there is an arc. The flat wire will be pressed by the belt. After passing through this section, the traction force of the flat wire will be increased, which is beneficial to making the coiled flat wire more compact.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: For the flat wire full-automatic wire take-up machine provided by the present invention, the flat wire is always in a continuous conveying state. Before reaching the coiling tool for coiling, the flat wire passes through the constant-speed wheel, the guide wheel, and the guide nozzle with a guiding groove, ensuring that the flat wire will not deflect or flip before coiling; and during the coiling process, the position of the flat wire guiding part remains unchanged. The forward and backward movement of the coiling tool is used to avoid wire take-up stacking. As the number of coiling layers gradually increases, the end of the guiding groove of the guide nozzle gradually retreats, so that the flat wire is always in a controlled state during coiling on the coiling tool, which is beneficial to improving the compactness of coiling; the starting section of the flat wire head is located in the guiding groove of the coiling tool, avoiding the problem of uneven wire take-up caused by the position of the wire head. In addition, when the wire take-up reaches both ends of the coiling tool, the outer pressing wheel and the inner pressing wheel are respectively used to press, ensuring that the wire take-up at the roots of both ends of the coiling tool is in place. During commutation, the coiling flatness can be ensured; after the wire take-up is completed, the turntable is used to swap the positions of the full coiling tool and the empty coiling tool. During this commutation process, the position of the flat wire guiding part and the wire take-up working position remain unchanged. The pulling of the flat wire, the wire catching of the empty spool wire catcher, the feeding of the flat wire into the cutting edge, and the cutting are all very smooth. The cutting mechanism realizes mechanical cutting, improving the cutting effect. And on the full coiling tool, the cut wire tail is pressed by the pressing wheel to prevent the coiled flat wire from loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention will be further described below in conjunction with specific implementation manners.

[0050] As Figure 1 shown, the flat wire full-automatic wire winding machine according to an embodiment of the present invention includes a frame 1, a wire arranging mechanism, and a wire winding mechanism. The wire arranging mechanism is installed on the frame 1, and the wire winding mechanism is a horizontal wire winding.

[0051] As Figure 1 and 4 shown, the wire winding mechanism includes a rotatable turntable 3, a turntable shaft 31, and two groups of rotatable wire winding shafts 32. The turntable 3 is installed on the front side of a turntable frame 30. The turntable frame 30 is welded and assembled from square tubes. A front side plate covers the front side of the turntable frame 30, and the turntable 3 is located on the front side of the front side plate. As Figures 5 to 11As shown in the figure, the turntable 3 is of a circular structure. The turntable shaft 31 is installed at the center of the turntable 3. The turntable shaft 31 is fixed to the turntable 3 by screws. A turntable bearing seat frame 311 is sleeved on the turntable shaft 31. The turntable bearing seat frame 311 and the turntable shaft 31 are connected by a bearing sleeve 312 and a bearing seat cover 313. The turntable shaft 31 can rotate relative to the turntable bearing seat frame 311. A large turntable gear 314 is installed on the turntable shaft 31. The large turntable gear 314 meshes with a small turntable gear 315. The small turntable gear 315 is connected to a turntable reduction motor 316. Two sets of take-up shafts 32 are symmetrically arranged left and right with respect to the turntable shaft 31. A take-up bearing seat 322 is sleeved on the take-up shaft 32. The take-up bearing seat 322 and the take-up shaft 32 are connected by a bearing 323 and a take-up bearing seat cover 324. The take-up bearing seat 322 is installed on the turntable 3. The take-up shaft 32 can rotate relative to the turntable 3. A large take-up gear 33 is installed at the end of the take-up shaft 32. The large take-up gear 33 meshes with a small take-up gear 331. The small take-up gear 331 is connected to a take-up reduction motor 332. The front end of the take-up shaft 32 is connected to a take-up connecting shaft 321. The take-up connecting shaft 321 is horizontally arranged relative to the horizontal plane. The take-up connecting shaft 321 is for installing the coil 100. A tray 4 is installed on two take-up shafts 32. The coil 100 is sleeved on the take-up shaft 32. One end face of the coil 100 is attached to the tray 4. The other end of the coil 100 is fixed by a center point 325 and a center point sleeve 326 and locked by a nut 327. The turntable bearing seat frame 311 can be moved back and forth relative to the wire arranging mechanism. During the take-up process, it is equivalent to the coil 100 moving back and forth, which can avoid the stacking of flat wires at a certain place on the coil 100.

[0052] As Figure 2 shown, the left and right sides of the turntable shaft 31 are respectively called the full coil working position A and the take-up working position B. The take-up working position B is used for taking up the empty coil 100. The full coil working position A is used for subsequent processing of the wound coil 100, such as loading and unloading the full coil 100 and installing the empty coil 100, ensuring the continuous and effective operation of this flat wire automatic take-up machine and avoiding the waste of wire segments during coil change.

[0053] As Figure 2 and 18As shown in the figure, the flat cable mechanism includes a guide wheel 24 and a guide nozzle 25. The guide wheel 24 is installed on the frame 1. A shaft is installed at the center of the guide wheel 24. The guide wheel 24 can rotate relative to the shaft. The shaft is installed on the top of the frame 1 through a fixing bracket 241. The guide wheel 24 is located on the front side of the frame 1 and is vertically arranged. The guide nozzle 25 is located on the side where the wire winding working position B is located. A guiding groove 251 for guiding the flat wire during transportation is provided at the lower part of the guide nozzle 25. The upper part of the guide nozzle 25 is rotatably installed on the frame 1. Specifically, a fixing seat 2501 is installed on the front side of the frame 1 below the fixing bracket 241. A track groove 2502 is provided on the fixing seat 2501. A movable bracket 2503 is installed in a matching manner on the fixing seat 2501. A support rod 2504 is fixed on the bracket 2503. The support rod 2504 is provided with a waist-shaped hole with an adjustable position. A shaft 2505 is fixed at the lower part of the support rod 2504. The upper part of the guide nozzle 25 is sleeved and installed on the shaft, and a spring 2506 is installed at the connection. By adjusting the relative positions of the support rod 2504, the bracket 2503, and the fixing seat 2501, the position adjustment of the guide nozzle 25 can be realized. The spring 2506 acts on the upper part of the guide nozzle 25, which is convenient for pulling and controlling the rotation and reset of the guide nozzle 25 when the upper part of the guide nozzle 25 rotates. A prolongation part 250 can be provided at the lower part of the guide nozzle 25, and the guiding groove 251 is arranged on the prolongation part 250. On the one hand, it is damaged and replaced to reduce costs. On the other hand, by replacing prolongation parts 250 with different specifications, it is applicable to flat wires with different size specifications.

[0054] During wire winding, the flat wire is guided by the guide wheel 24 and the guiding groove 251 and then wound on the coil 100. The coil 100 moves back and forth with the rotary table bearing seat frame 311. As the flat wire wound on the coil 100 thickens, the lower part of the guide nozzle 25 gradually retreats.

[0055] The installation structure for the forward and backward movement of the rotary table bearing seat frame 311: As Figures 5 to 7As shown in the figure, a sliding seat 34 is fixedly connected to the bottom of the turntable bearing seat 311 by screws, and the sliding seat 34 is fixed to the turntable frame 30. A bottom plate 341 is installed on the frame 1, and the sliding seat 34 is installed on the bottom plate 341 through a linear guide slider assembly 342. A wire take-up displacement motor 343 is installed on the bottom plate 341, and a lead screw nut assembly 344 is installed at the bottom of the sliding seat 34. The wire take-up displacement motor 343 and the lead screw nut assembly 344 are driven by a synchronous belt 345 and a pulley. The wire take-up displacement motor 343 drives the lead screw nut assembly 344 to rotate, thereby driving the sliding seat 34 to move back and forth. The turntable bearing seat 311 connected to the sliding seat 34 moves back and forth accordingly, which is equivalent to the movement of the coil holder 100 back and forth. During the wire take-up process, the installation positions of the guide pulley 24 and the guide nozzle 25 remain unchanged. In this way, before the flat wire reaches the coil holder 100 for wire take-up, it is not easy to deflect or flip. To prevent the flat wire on the coil holder 100 from being pushed to one place, the wire take-up displacement motor 343 is used to drive the lead screw nut assembly 344 to move the sliding seat 34 back and forth, thereby realizing the back-and-forth movement of the coil holder 100.

[0056] As Figure 8 shown, an inlet groove 101 is formed on the inner end face 102 of the coil holder 100 near the turntable 3. The inlet direction of the inlet groove 101 is inclined, and the caliber at the inlet is slightly wider. In this way, before the flat wire is officially wound on the coil holder 100, the starting section of the flat wire is located in the inlet groove 101, avoiding improper handling of the wire head and resulting in an uneven surface after winding.

[0057] As Figure 2 and 18 shown, the starting section of the flat wire is pressed on the inlet groove 101. During the continuous conveying process of the flat wire, after being led down by the guide pulley 24, it will reach the coil holder 100 through the guiding groove 251 of the guide nozzle 25. During the wire take-up process, the installation position of the guide nozzle 25 remains unchanged, and the coil holder 100 rotates and moves back and forth relative to the guide nozzle 25 to cooperate with the flat wire to be evenly arranged on the coil holder 100 during the wire take-up process. When the flat wire is wound on the coil holder 100, the guide nozzle 25 always adheres to the surface of the coil holder 100. As the number of layers of the flat wire wound on the coil holder 100 gradually increases, the front end of the guide nozzle 25 is pushed to gradually retreat. Therefore, the position of the starting section of the flat wire is set reasonably to ensure that the starting section of the flat wire fits with the coil holder 100 to avoid the situation of protruding during winding. The guide nozzle 25 controls the guiding of the flat wire in real time and ensures the tightness during winding.

[0058] When the flat wire is being wound up, it is necessary to ensure that the flat wire is wound to the edge as much as possible, that is, closer to the roots of the two end faces of the coil holder 100. After the flat wire is wound to the edge, it is necessary to adjust the wire winding direction to wind the wire back and forth. The coil holder 100 moves back and forth. The treatment of the wire segment when the coil holder 100 changes the wire winding direction is also very crucial. Otherwise, it will easily lead to situations such as not reaching the edge, loosening, and unevenness. For this reason, the automatic flat wire winder is provided with a wire pressing mechanism 5, and the wire pressing mechanism 5 is located on the side where the wire winding working position B is located.

[0059] As Figures 12 to 15 shown, the wire pressing mechanism 5 includes an outer pressure wheel 51, an inner pressure wheel 52, and a pressure wheel fixing seat 58. The pressure wheel fixing seat 58 is installed on the front side of the frame 1 through a bracket 59. On one side of the pressure wheel fixing seat 58 close to the guiding nozzle 25, there is a pressure wheel sliding table 56 that can move relative to the pressure wheel fixing seat 58. A guide rail 571 and a slider 572 are arranged between the pressure wheel fixing seat 58 and the pressure wheel sliding table 56. A cylinder 573 is installed on the bracket 59, and the piston rod of the cylinder 573 is connected to the pressure wheel sliding table 56 to drive the movement of the pressure wheel sliding table 56. A horizontally arranged wire pressing shaft rod 55 is installed on the side surface of the pressure wheel sliding table 56. Two wire pressing arms 53 are hinged to the wire pressing shaft rod 55, and the outer pressure wheel 51 and the inner pressure wheel 52 are respectively rotatably installed at the front ends of the two wire pressing arms 53. Two independent wire pressing cylinders 54 are hinged to the two wire pressing arms 53 respectively. The bottom of the pressure wheel sliding table 56 is connected with a cylinder mounting plate 561, and the other end (i.e., the cylinder body part) of the wire pressing cylinder 54 is hinged to the cylinder mounting plate 561. When the wire is wound to the roots of the two ends of the coil holder 100, the wire pressing cylinder 54 drives the wire pressing arms 53, so that the outer pressure wheel 51 and the inner pressure wheel 52 respectively press the flat wire wound at the roots of the two ends of the coil holder 100.

[0060] For the two end faces of the coil holder 100, the end face close to the turntable 3 is called the inner end face 102, and the end face far from the turntable 3 is called the outer end face 103. When the wire is wound to the edge, the one used to press against the outer end face 103 is called the outer pressure wheel 51, and the one used to press against the inner end face 102 is called the inner pressure wheel 52. A shaft is installed at the center of both the outer pressure wheel 51 and the inner pressure wheel 52, and the outer pressure wheel 51 and the inner pressure wheel 52 are installed at the front ends of the wire pressing arms 53 through the shafts. To protect the surface of the flat wire, both the outer pressure wheel 51 and the inner pressure wheel 52 are made of nylon wheels. The end faces of the outer pressure wheel 51 and the inner pressure wheel 52 far from the wire pressing arms 53 are both provided with a stepped structure 50, that is, the diameter of the end face is slightly smaller. In this way, when the flat wire is wound to the root of the coil holder 100 and the direction is changed, the position near the root of the coil holder 100 is one layer thicker. Through the stepped outer pressure wheel 51 and inner pressure wheel 52, it can be ensured that the tightness between the layer of flat wire covered after the direction change and the previous layer of flat wire is good, and the surface of the flat wire is avoided from being over-pressed.

[0061] A wire pressing mechanism 5 is installed at the wire take-up working position B. When the flat wire is wound to the roots at both ends of the coil 100 for each layer, the corresponding wire pressing cylinder 54 extends, the wire pressing arm 53 rotates around the wire pressing shaft rod 55, and the outer pressure wheel 51 or the inner pressure wheel 52 presses against the flat wire being wound on the coil 100, so that the flat wire can also be tightly wound at the roots of the coil 100. During the commutation and wire arranging, the flat wire can be carried out in an orderly manner, ensuring the flatness after the wire is wound at the roots at both ends of the coil 100 and guaranteeing that the wire is wound in place at the roots at both ends of the coil 100.

[0062] As Figure 2 、 3 and shown in Figure 5, a wire catcher 41 is fixedly installed on the edge of each tray 4. A wire blocking rod 71 is provided beside each tray 4. The main body of the wire blocking rod 71 is an arc section. Both ends of the wire blocking rod 71 are fixedly installed on the turntable 3. The wire blocking rod 71 is close to the edge of the tray 4. The main function of the wire blocking rod 71 is that when changing the coil between the empty coil 100 and the full coil 100, on the full coil working position A, when the full coil 100 rotates, since the wire blocking rod 71 blocks the pulled flat wire segment, the wire catcher 41 on this side of the tray 4 will not catch the flat wire. A wire blocking roller 72 is provided on the side of the wire blocking rod 71 away from the tray 4. A cutting mechanism 8 and a blocking rod 73 are arranged between the wire blocking roller 72 and the side of the tray 4 where the wire blocking rod 71 is not provided. The blocking rod 73 is located between the cutting mechanism 8 and the wire blocking roller 72. The turntable 3 is equipped with a blocking rod cylinder 731. One end of the blocking rod 73 is installed on the piston rod of the blocking rod cylinder 731. The position of the blocking rod 73 can be lifted by using the blocking rod cylinder 731. During the coil change, the blocking rod 73 can be used to press the flat wire into the guiding groove 101 of the coil 100.

[0063] During the coil change, the turntable 3 rotates, the full coil 100 after wire winding rotates to the full coil working position A, and the empty coil 100 to be wire wound rotates to the wire take-up working position B. The flat wire is pulled to the lower part of the wire blocking roller 72 beside the full coil 100. The blocking rod 73 presses down, and the flat wire is pressed into the guiding groove 101 of the empty coil 100. After the wire catcher 41 at the wire take-up working position B catches the wire, the flat wire is cut in the cutting mechanism 8.

[0064] When taking up the wire, the spool 100 rotates clockwise. Before changing the spool, the empty spool 100 is pre-installed on the wire take-up connecting shaft 321 at the full spool working position A. The turntable 3 rotates in the reverse direction to adjust the positions of the full spool 100 and the empty spool 100. The full spool 100 rotates to the full spool working position A, and the empty spool 100 to be wound rotates to the wire take-up working position B. Meanwhile, the continuously conveyed flat wire is pulled to the full spool working position A along with the full spool 100. The flat wire passes under the wire guide roller 72 beside the full spool 100 (i.e., the wire guide roller 72 located under the turntable 3 after rotation). The stop rod cylinder 731 is in the extended state. The stop rod 73 is above the flat wire and the flat wire is outside the cutting mechanism 8. Then, the stop rod cylinder 731 drives the stop rod 73 to press down the flat wire, and the flat wire is pressed into the guiding groove 101 of the empty spool 100. The empty spool 100 and the tray 4 rotate, so that the wire catcher 41 at the wire take-up working position B hooks the flat wire. After the wire catcher 41 hooks the flat wire, it continues to rotate and pushes the flat wire into the cutting mechanism 8 to complete the cutting.

[0065] As Figures 19 to 23 shown, the cutting mechanism 8 includes a tool holder 83, a cutting cylinder 82 and a cutting blade plate 81. The tool holder 83 is installed on the turntable 3 by screws ( Figure 8 shown). The tool holder 83 is fixedly installed with a tool side plate 84 by screws. The cutting blade plate 81 is rotatably installed on the tool side plate 84. The rear end of the cutting blade plate 81 is hinged to the piston rod of the cutting cylinder 82, and the cylinder body of the cutting cylinder 82 is installed on the tool holder 83. A cutting edge 841 is provided on the front side of the tool side plate 84. The cutting edge 841 is a replaceable cutting edge, and the replaceable cutting edge 841 can be locked to the tool side plate 84 by screws. A cutting edge opening 80 is formed between the front part of the cutting blade plate 81 and the cutting edge 841. The cutting cylinder 82 drives the front end of the cutting blade plate 81 to press down, and the cutting edge opening 80 closes to cut the flat wire. The cutting edge opening 80 formed between the cutting blade plate 81 and the cutting edge 841 is an inclined cutting edge opening, and the cutting edge opening 80 is gradually inclined upward from the front end of the cutting blade plate 81 to the rear.

[0066] On one side of the cutting blade plate 81, a guide plate 85 is installed through a side plate 86 and screws, so that the guide plate 85 is fixed to the tool holder 83. The bottom of the front end of the guide plate 85 is inclined. When the wire catcher 41 after hooking the wire rotates and pushes the flat wire under the guide plate 85, along the inclined edge 851 at the front end of the guide plate 85, it is smoothly guided under the cutting blade plate 81 to assist the flat wire to accurately reach the position of the cutting edge opening 80.

[0067] A travel switch 87 is also installed at the front end of the tool holder 83. The travel switch 87 is provided with a contact rod 88. The contact rod 88 is upward and located between the guide plate 85 and the cutting blade plate 81. One end of the contact rod 88 is installed on the travel switch 87, and the contact rod 88 can rotate around the connection point.

[0068] As Figure 3 and 19As shown, after the full spool 100 and the empty spool 100 are changed, before the flat wire is pushed by the wire catcher 41 to the cutting mechanism 8, the flat wire is perpendicular to the turntable 3. When it touches the front inclined surfaces of the guide plate 85 and the tangent knife plate 81, it gradually tilts. Then, before the flat wire enters the knife edge 80 from the guide plate 85, it first touches the contact rod 88. The flat wire pushes the contact rod 88, and the contact rod 88 rotates backward. As the contact rod 88 rotates, the flat wire flips along the inclined knife edge. After the contact rod 88 rotates in place, it triggers the cutting cylinder 82 to start. The cutting cylinder 82 extends to drive the rear end of the tangent knife plate 81 to lift upward, the tangent knife plate 81 rotates, the front end of the tangent knife plate 81 presses downward, and the knife edge 80 closes to cut the flat wire. By applying an external force through the cutting cylinder 82 to cut the flat wire, the acting force during cutting is increased, which is more reliable than the traditional method of pulling and hitting the blade to break the wire, and this structure is also suitable for flat wires with larger dimensions. The inclined knife edge changes the direction of the flat wire and makes it flip, so that the force required for cutting can be reduced, which is beneficial to cutting. In addition, if the blade 841 is worn, it can be replaced to reduce costs.

[0069] After the full spool 100 finishes winding the wire and the flat wire is cut, to ensure that the flat wire wound on the spool 100 does not come loose, a pressing mechanism 6 is provided in this fully automatic flat wire winding machine. The pressing mechanism 6 is located on the side where the full spool working position A is located.

[0070] As Figure 1 and 16 shown, the pressing mechanism 6 includes a pressing wheel 61 and a pressing cylinder 64. A horizontally arranged pressing shaft rod 63 is installed on the front side plate of the turntable frame 30. The pressing shaft rod 63 is hinged with a pressing arm 62. The pressing arm 62 is sleeved on the pressing shaft rod 63, and a linear bearing 67 is provided between the pressing arm 62 and the pressing shaft rod 63 to facilitate the movement of the pressing shaft rod 63 relative to the pressing arm 62. The pressing wheel 61 is rotatably installed at the front end of the pressing arm 62. There is a compressible spring 66 between the pressing wheel 61 and the pressing arm 62. If the end face of the pressing wheel 61 touches the inner end face 102 of the spool 100, the pressing wheel 61 has room to retreat to avoid excessive extrusion. A pressing fixed seat 65 is installed on the front side of the frame of the machine frame 1. The cylinder body of the pressing cylinder 64 is hinged with the pressing fixed seat 65, and the piston rod of the pressing cylinder 64 is hinged with the side surface of the pressing arm 62. When the rotational speed of the full spool 100 decreases and the full spool 100 rotates to the full spool working position A, the pressing cylinder 64 extends, the pressing arm 62 rotates around the pressing shaft rod 63, and the pressing wheel 61 presses against the wire wound on the surface of the full spool 100, which can prevent the wire tail of the flat wire from getting out of control and causing the wound flat wire to come loose after the flat wire is cut.

[0071] This fully automatic flat wire winding machine also includes a traction mechanism, as Figure 1 and 17As shown in the figure, the traction mechanism includes an inner guide wheel 21, an outer guide wheel 22, a constant-speed wheel 23 and a tensioning assembly. The inner guide wheel 21 and the outer guide wheel 22 are rotatably mounted on the top of the frame 1. The outer guide wheel 22 is aligned with the guide wheel 24. The constant-speed wheel 23 is rotatably mounted on the frame 1 through a shaft. A traction motor 231 is connected to the shaft of the constant-speed wheel 23. The inner guide wheel 21 is located obliquely above the constant-speed wheel 23. The tensioning assembly includes a pulley assembly 232 on one side of the constant-speed wheel 23 and a belt 233 wound around the pulley assembly 232. The belt 233 covers an arc edge of the constant-speed wheel 23. The pulley assembly 232 has four pulleys. Two of the pulleys are respectively located obliquely above and obliquely below the left side of the constant-speed wheel 23, and the other two pulleys are located on the left side of the constant-speed wheel 23. The pulley located below on the left side is provided with an adjustable structure. By finely adjusting the up and down positions of the pulley, the tension of the belt 233 is adjusted. The adjustable structure includes a movable plate 234, a threaded rod 235 and a nut 236. The central axis of the pulley is perpendicularly connected to the threaded rod 235. A guiding portion 237 through which the threaded rod 235 passes is fixed on the movable plate 234. There is a front side plate 11 behind the constant-speed wheel 23, and a positioning portion 238 is fixed on the front side plate 11. The threaded rod 235 passes through the positioning portion 238. After the movable plate 234 is adjusted in place, the threaded rod 235 is clamped on the positioning portion 238 by two nuts 236. By adjusting the relative positions of the movable plate 234 and the positioning portion 238, the fine adjustment of the up and down positions of the pulley is realized. Before the flat wire enters the outer guide wheel 22, it first bypasses the constant-speed wheel 23. When passing through the surface of the constant-speed wheel 23, there is an arc. The flat wire will be pressed by the belt 233. After passing through this section, the traction force of the flat wire will be increased, which is beneficial to making the wound flat wire more compact, and the conveying speed of the flat wire can be controlled by adjusting the rotation speed of the traction motor 231.

[0072] Combined with Figure 2 and 3 , the working process is specifically described as follows: The arrowed lines in the figure represent the running path of the flat wire. First, the flat wire is arranged according to the set path. The flat wire passes through the inner guide wheel 21, winds from the left side to the right side of the constant-speed wheel 23. At this time, the belt 233 ( Figure 17 as shown) on the left side of the constant-speed wheel 23 presses a section of the flat wire, passes under the outer guide wheel 22, bypasses the guide wheel 24, and passes through the guiding groove 251 of the guiding nozzle 25. The leading end of the flat wire is introduced into the guiding groove 101 of the reel 100 where the wire-receiving working position B is located and the leading end is fixed; Start the equipment, and the traction motor 231, the wire-receiving reduction motor 332, and the wire-receiving displacement motor 343 start to work ( Figure 10As shown in the figure, the take-up reduction motor 332 drives the take-up reduction motor 332 to drive the bobbin 100 to rotate. The take-up displacement motor 343 drives the turntable bearing seat 311 to drive the bobbin 100 to move back and forth. The flat wire is wound on the surface of the bobbin 100. When the flat wire reaches the edge during take-up, that is, at the two ends of the bobbin 100, the pressing cylinder 54 starts to drive the corresponding pressing arm 53 to rotate, so that the outer pressing wheel 51 or the inner pressing wheel 52 presses the flat wire reaching the edge. As the number of take-up layers gradually increases, the end where the guiding groove 251 of the guiding nozzle 25 is located gradually retreats. When the bobbin 100 at the take-up working position B is almost full, the rotation speed of the bobbin 100 decreases, and an empty bobbin 100 to be taken up is installed in advance at the full-bobbin working position A. The turntable 3 reducer starts, driving the turntable shaft 31 to rotate clockwise. The full-bobbin 100 rotates to the full-bobbin working position A, and the empty bobbin 100 to be taken up rotates to the take-up working position B. As the position of the bobbin 100 changes, the continuously conveyed flat wire is pulled to the full-bobbin working position A along with the full-bobbin 100. The flat wire passes under the wire blocking roller 72 (i.e., the wire blocking roller 72 located under the turntable 3 after rotation) beside the full-bobbin 100. The blocking rod cylinder 731 is in the extended state. The blocking rod 73 is above the flat wire and the flat wire is outside the cutting mechanism 8. The blocking rod cylinder 731 drives the blocking rod 73 to press down the flat wire, and the flat wire is pressed into the guiding groove 101 of the empty bobbin 100. The empty bobbin 100 and the tray 4 rotate, so that the wire catcher 41 at the take-up working position B catches the flat wire. At this time, due to the action of the wire blocking rod 71, the wire catcher 41 at the full-bobbin position will not catch the flat wire. After the wire catcher 41 at the empty bobbin 100 catches the flat wire, it continues to rotate and pushes the flat wire towards the guiding plate 85 ( Figure 19 As shown in the figure), along the hypotenuse at the front end of the guiding plate 85, it is smoothly guided under the tangent knife plate 81, and then to the contact rod 88. The flat wire pushes the contact rod 88, and the contact rod 88 rotates backward. As the contact rod 88 rotates, the flat wire flips along the inclined cutting edge. After the contact rod 88 rotates in place, it triggers the start of the cutting cylinder 82, and the front end of the tangent knife plate 81 presses down, and the cutting edge 80 closes to cut the flat wire. Before the flat wire is cut, at the full-bobbin working position A, the pressing cylinder 64 starts, and the pressing arm 62 rotates to make the pressing wheel 61 press against the flat wire wound on the surface of the full-bobbin 100, so as to prevent the wound flat wire from becoming loose after the flat wire is cut.

[0073] The fully automatic flat wire winding machine provided by the present invention has the flat wire in a continuous conveying state. Before reaching the winding on the winding reel 100, the flat wire passes through the constant speed wheel 23, the guiding wheel 24, and the guiding nozzle 25 with the guiding groove 251, ensuring that the flat wire will not skew or flip before winding. And during the winding process, the position of the flat wire guiding part remains unchanged. The front and back movement of the winding reel 100 is used to avoid the stacking of the wound wire. As the number of winding layers gradually increases, the end where the guiding groove 251 of the guiding nozzle 25 is located gradually retreats, so that the flat wire is always in a controlled state during winding on the winding reel 100, which is beneficial to improving the tightness of winding. The starting section of the flat wire head is located in the guiding groove 101 of the winding reel 100, avoiding the problem of uneven winding caused by the position of the wire head. In addition, when winding to both ends of the winding reel 100, the outer pressing wheel 51 and the inner pressing wheel 52 are respectively used to press, ensuring that the winding at the roots of both ends of the winding reel 100 is in place, and the flatness of winding can be ensured during commutation. After the winding is completed, the turntable 3 is used to exchange the positions of the full winding reel 100 and the empty winding reel 100. During this commutation process, the position of the flat wire guiding part and the winding working position B remain unchanged, and the pulling of the flat wire, the wire catching of the empty reel wire catcher 41, the feeding of the flat wire into the cutting edge 80, and the cutting are all very smooth. The cutting mechanism 8 realizes mechanical cutting, improving the cutting effect. And on the full winding reel 100, the cut wire tail is pressed by the pressing wheel 61 to prevent the wound flat wire from loosening.

[0074] The above are only some embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, other deformations and improvements can be made, and these all belong to the protection scope of the present invention.
