Description

Technical Field

[0001] The invention relates to the technical field of enameled wire processing, in particular to an engine enameled wire winding device. Background Art

[0002] Enameled wire is an electric wire with insulating paint coated on the surface of the conductor. The surface of the enameled wire is coated with a layer of insulating paint, which can effectively isolate the conductor from the outside world and prevent current leakage and short circuit. The type and thickness of the insulating paint can be selected according to different usage requirements to meet different insulation levels. Enameled wire is the main raw material for products such as engines, motors, electrical appliances and household appliances. Especially in the rapid development of the electric power industry and household appliances, the application of enameled wire has become more extensive. There are many types of enameled wire, including acetal enameled wire, polyester enameled wire, polyurethane enameled wire, etc. Each enameled wire has its specific application and characteristics.

[0003] For example, a coiling device for producing enameled wires with publication number CN119018705A proposes that during the production process of the enameled wires, an external coiling device is required to be used for winding the enameled wires. However, during the use of the existing coiling device, the corresponding enameled wires are wound in one place because the corresponding wire mechanism is not installed inside, resulting in poor winding effect on the outer surface of the corresponding winding roller. By setting a winding component, when the cleaned enameled wire reaches the auxiliary wheel through the rotating wheel, the winding component is set so that the cleaned enameled wire is wound on the winding wheel through the rotating wheel and the auxiliary wheel, and then the connecting plate is driven by the output end of the motor to move back and forth to evenly wind the enameled wire on the winding plate. At the same time, when the enameled wire and the winding plate are wound and extruded, the winding plate is subjected to an extrusion force, so that the winding plate drives the connecting rod to move toward the arc groove, so that the connecting rod and the arc groove are offset. At the same time, by evenly setting limited blocks on the winding plate, the enameled wire can be better wound in sections, thereby avoiding the phenomenon that the enameled wire wound on the winding plate is wound in one place.

[0004] However, enameled wire is usually composed of metal wire (such as copper wire or aluminum wire) and insulating paint. Metal wires such as copper wire and aluminum wire have certain ductility and elasticity and can be bent and stretched to a certain extent. Figure 7 As shown, due to the position of the winding roller and the output position of the enameled wire, the winding roller and the enameled wire will not always maintain the same angle, and the winding angle changes periodically. From the force analysis, it can be clearly concluded that the tension on the enameled wire is different at different winding angles, that is, the tension on the enameled wire is changing, so the elongation of the enameled wire will also change periodically, which will lead to different winding tightness of the enameled wire on the wire roller, and in severe cases, it may lead to obvious contrast in thickness of the enameled wire; In addition, as the winding thickness increases, such as Figure 7As shown in the figure, the oblique pulling force at the same angle position is also different when the winding thickness changes. The periodically changing pulling force of the winding roller on the enameled wire will enter another cycle. Therefore, even if the tension balance of the enameled wire at different angles is achieved, after the winding thickness increases, the tension periodic change of the enameled wire will show new changes. It is difficult to achieve the tension balance of the enameled wire under the two conditions of changing winding angle and winding thickness at the same time.

[0005] Therefore, how to maintain the tension (extension) of the enameled wire without obvious difference during the winding process of the enameled wire (including changes in the winding angle and the winding thickness) is the core problem that the present invention aims to solve. Summary of the invention

[0006] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide an engine enameled wire winding device to solve the problem that the above-mentioned background technology is limited by the position of the winding roller and the output position of the enameled wire. The winding roller and the enameled wire will not always maintain the same angle, and the winding angle changes periodically. From the force analysis, it can be clearly concluded that the pulling force on the enameled wire at different winding angles is different, that is, the tension on the enameled wire is changing, and thus the elongation of the enameled wire will also show periodic changes, which will result in different winding tightness of the enameled wire on the wire roller, and in severe cases may lead to a significant contrast in the thickness of the enameled wire.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an engine enameled wire winding device, comprising a workbench and a winding mechanism fixed on the upper surface of the workbench for winding the enameled wire, and also comprising a thickness sensing plate located on the side of a winding roller of the winding mechanism, a tension balancer for regulating the winding tension and secondary guiding the enameled wire, and a pressure regulating chamber arranged inside the tension balancer for adaptively adjusting the winding thickness change, an oil storage chamber fixed on the upper surface of the workbench for identifying and transmitting the thickness signal of the enameled wire wound on the winding roller is installed between the thickness sensing plate and the tension balancer.

[0008] Preferably, a center-through wire hub for centering the enameled wire is fixed on the upper surface of the workbench, and the thickness sensing plate fits the enameled wire wound outside the winding roller, and the upper and lower ends of the thickness sensing plate and the adjacent surfaces of the winding roller are chamfered.

[0009] Preferably, one end of a plurality of groups of telescopic rods are equidistantly fixed to a side of the thickness sensing plate away from the winding roller, and the other end of the telescopic rod passes through the side wall of the oil storage chamber and is fixedly connected to a piston plate.

[0010] Preferably, a return spring is wound around the outer wall of the telescopic rod, one end of the return spring is welded to the side wall of the thickness sensing plate, and the other end of the return spring is fixed to the outer wall of the oil storage chamber.

[0011] Preferably, an oil storage cavity that is slidably matched with the piston plate is provided inside the oil storage chamber, and a sealing member that is slidably matched with the inner wall of the oil storage cavity is provided on the edge of the piston plate.

[0012] Preferably, a one-way screw is installed on the upper surface of the oil storage chamber, and the outer wall of the one-way screw is threadedly connected to a wire pressing assembly for pulling and guiding the enameled wire. The wire pressing assembly consists of a middle-through upper end for allowing the enameled wire to pass through and a lower end threadedly connected to the one-way screw, and the lower surface of the wire pressing assembly is stably fitted with the upper surface of the oil storage chamber.

[0013] Preferably, a support plate is fixedly installed on the upper surface of the workbench, and a servo motor is fixedly installed on the outer side of the support plate, the output rotor of the servo motor is fixedly connected to one end of a connecting rod, and the other end of the connecting rod is respectively fixedly connected to the ends of a tension balancer and a pressure regulating chamber, one end of a belt is installed on the outer wall of the connecting rod, and the other end of the belt is sleeved on the outer wall of the end of the one-way screw.

[0014] Preferably, the tension balancer is composed of two symmetrically arranged conical spiral plates connected with a unified spiral trajectory, and the spiral direction of the spiral plates is consistent with the thread direction of the one-way screw, and the small diameter ends of the conical spiral plates are symmetrically distributed at both ends of the tension balancer.

[0015] Preferably, the pressure regulating chamber is arranged to fit in with the inner space of the tension balancer, and the outer wall of the pressure regulating chamber is made of elastic material and is arranged to fit in with the inner wall of the tension balancer; One end of the pressure regulating chamber is connected to a rotating rod, and the inside of the rotating rod is connected to a plug rod in a rotating manner, and the outer end of the plug rod is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to the oil storage chamber; The other end of the pressure regulating chamber is closed and fixedly connected to the end of the tension balancer.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Balance of tension of enameled wire winding angle within the same winding thickness level: When the enameled wire is at the end with the largest winding angle, that is, when the tension at both ends is the largest, the tension balancer will lift the enameled wire to the smallest degree. As the winding progresses, the winding angle of the enameled wire gradually decreases, but the conical spiral groove of the tension balancer will produce a gradually increasing lifting effect on the enameled wire. When the enameled wire is wound to the center where the tension is the smallest, the tension balancer lifts the enameled wire to the largest degree. Then, the enameled wire approaches the other end of the winding roller, and its winding angle and winding tension gradually increase symmetrically. Similarly, the conical spiral groove at the other end of the tension balancer will produce a gradually decreasing lifting effect on the enameled wire, thereby ensuring that the winding tension of the enameled wire at the same thickness will not be significantly different, thereby ensuring that the enameled wire has the same extension amount, so as to avoid the difference in the tightness of the paint winding caused by the different extension amounts of the enameled wire and the obvious contrast in the thickness of the enameled wire after winding. 2. Tension balance of enameled wire winding angle at different winding thickness levels: When the thickness sensing plate detects the thickness change of the winding, the thickness sensing plate will move one thickness unit toward the oil storage chamber, so that the piston plate moves one thickness unit in the oil chamber of the oil storage chamber and injects the oil corresponding to one thickness unit space inside the oil storage chamber into the pressure regulating chamber through the connecting pipe and the middle-through plug rod. Since the pressure regulating chamber is wrapped and restricted by the spiral tension balancer and the pressure regulating chamber is made of thin-walled rubber, the outer wall of the pressure regulating chamber will deform and bulge evenly in the spiral groove of the tension balancer, and the amount of bulge just corresponds to one thickness unit on the winding roller. At the same time, since the enameled wire is fitted with the outer wall of the pressure regulating chamber in the spiral groove, when the pressure regulating chamber bulges from the spiral groove, the outer wall of the pressure regulating chamber bulging in the spiral groove will further lift the enameled wire upward to adapt to the angle change in another direction brought about by the increase in winding thickness, thereby balancing the winding tension change caused by the angle change in the other direction, thereby achieving further adaptive balance of the enameled wire tension change caused by the increase in winding thickness on the basis of balancing the winding angle.

[0017] The overall tension balance under the two variables of winding angle and winding thickness is achieved during the winding process of the enameled wire, so as to ensure that there will be no obvious difference in the winding tension of the enameled wire at different winding thicknesses, thereby ensuring that there will be no obvious difference in the elongation of the wound enameled wire.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 7 The present invention provides a technical solution: an engine enameled wire winding device, comprising a workbench 1 and a winding mechanism 2 fixed on the upper surface of the workbench 1 for winding the enameled wire, and also comprising a thickness sensing plate 3 located on the side of the winding roller of the winding mechanism 2, a tension balancer 7 for adjusting the winding tension and secondary guiding the enameled wire, and a pressure regulating chamber 8 arranged inside the tension balancer 7 for adaptively adjusting the winding thickness change, and an oil storage chamber 4 fixed on the upper surface of the workbench 1 for identifying and transmitting the thickness signal of the enameled wire wound on the winding roller is installed between the thickness sensing plate 3 and the tension balancer 7.

[0028] A central conductor hub 11 for centering the enameled wire is fixed on the upper surface of the workbench 1, and the thickness sensing plate 3 fits the enameled wire wound outside the winding roller, and the upper and lower ends of the thickness sensing plate 3 and the adjacent surface of the winding roller are chamfered.

[0029] One end of a plurality of telescopic rods 31 is equidistantly fixed to one side of the thickness sensing plate 3 away from the winding roller, and the other end of the telescopic rod 31 penetrates the side wall of the oil storage chamber 4 and is fixedly connected to a piston plate 33 .

[0030] A return spring 32 is wound around the outer wall of the telescopic rod 31 , one end of the return spring 32 is welded to the side wall of the thickness sensing plate 3 , and the other end of the return spring 32 is fixed to the outer wall of the oil storage chamber 4 .

[0031] An oil storage cavity that is slidably fitted with the piston plate 33 is provided inside the oil storage chamber 4, and a sealing member 34 that is fitted with the inner wall of the oil storage cavity is provided on the edge of the piston plate 33.

[0032] A one-way screw rod 41 is installed on the upper surface of the oil storage chamber 4, and the outer wall of the one-way screw rod 41 is threadedly connected to a wire pressing assembly 42 for pulling and guiding the enameled wire. The wire pressing assembly 42 consists of a middle-through upper end for the enameled wire to pass through and a lower end threadedly connected to the one-way screw rod 41, and the lower surface of the wire pressing assembly 42 is stably fitted with the upper surface of the oil storage chamber 4.

[0033] A support plate 5 is fixedly installed on the upper surface of the workbench 1, and a servo motor 6 is fixedly installed on the outer side of the support plate 5. The output rotor of the servo motor 6 is fixedly connected to one end of a connecting rod 71, and the other end of the connecting rod 71 is respectively fixedly connected to the ends of the tension balancer 7 and the pressure regulating chamber 8. One end of a belt 61 is installed on the outer wall of the connecting rod 71, and the other end of the belt 61 is sleeved on the outer wall of the end of the one-way screw rod 41.

[0034] The tension balancer 7 is composed of two symmetrically arranged conical spiral plates connected with a unified spiral trajectory, and the spiral direction of the spiral plates is consistent with the thread direction of the one-way screw 41, and the small diameter ends of the conical spiral plates are symmetrically distributed at both ends of the tension balancer 7.

[0035] The pressure regulating chamber 8 is arranged to fit the inner space of the tension balancer 7, and the outer wall of the pressure regulating chamber 8 is made of elastic material and is arranged to fit the inner wall of the tension balancer 7; One end of the pressure regulating chamber 8 is connected to a rotating rod 72, and the inside of the rotating rod 72 is connected to a plug rod 81 in a through-type rotational manner. The outer end of the plug rod 81 is through-type installed with one end of a connecting pipe 9, and the other end of the connecting pipe 9 is connected to the oil storage chamber 4. The other end of the pressure regulating chamber 8 is closed and fixedly connected to the end of the tension balancer 7 .

[0036] like Figure 1 and Figure 2As shown, the winding end of the enameled wire is passed through the wire hub 11 and clamped in the first spiral gap at the end of the tension balancer 7, and then the enameled wire end is passed through the middle gap at the upper end of the wire pressing assembly 42 and wound around the outer wall of the end of the winding roller (it can be wound a few more times initially to prevent loosening), and then the thickness sensing plate 3 is pushed to make the thickness sensing plate 3 approach the oil storage chamber 4 and open the gap to stably insert the enameled wire end initially wound on the winding roller into the gap, and finally the thickness sensing plate 3 is released. Under the action of multiple sets of reset springs 32, the thickness sensing plate 3 is quickly reset to press the enameled wire end and the initially wound coil against the outer wall of the winding roller, and at this time, the guiding and clamping of the enameled wire end are completed.

[0037] Next, the winding mechanism 2 and the servo motor 6 are started synchronously. The continuous and stable rotation of the winding mechanism 2 will drive the enameled wire to gradually rotate and wind on the winding roller, and the rotation speed of the winding mechanism 2 is consistent with the output rotation speed of the servo motor 6. When the winding mechanism 2 starts to wind, the servo motor 6 will also synchronously drive the tension balancer 7 and the pressure regulating chamber 8 to rotate at a constant speed, and synchronously drive the one-way screw 41 to rotate at a constant speed through the belt 61. Since the enameled wire is engaged with the thread groove inside the tension balancer 7 and the inner wall of the thread groove is attached to the pressure regulating chamber 8 made of rubber, when the winding mechanism 2 is wound one circle, the tension balancer 7 also rotates one circle and pushes the enameled wire to the next level of spiral. At the same time, the one-way screw 41 also rotates one circle to make the wire pressing assembly 42 carry the enameled wire forward one winding unit along the winding direction; This is the tension adjustment for the winding angle of the enameled wire when the thickness remains unchanged. Figure 7 From the force analysis shown, it can be seen that when the enameled wire approaches the center from the winding end, the angle changes step by step from large to small. At the same time, when it approaches the end from the winding center, the angle changes step by step from small to large. The larger the angle, the greater the tension on the enameled wire at both ends, and the greater the extension. The setting of the tension balancer 7 is used to balance the change in the pulling tension caused by the change in the winding angle. Specifically, when the enameled wire is at the end with the largest winding angle, that is, when the tension on both ends is the largest, the tension balancer 7 lifts the enameled wire upward to the minimum. As the winding progresses, The winding angle of the enameled wire gradually decreases, but the tapered spiral groove of the tension balancer 7 will produce a gradually increasing lifting effect on the enameled wire. When the enameled wire is wound to the center where the tension is the smallest, the tension balancer 7 lifts the enameled wire to the maximum extent. Then, the enameled wire approaches the other end of the winding roller, and its winding angle and winding tension gradually increase symmetrically. Similarly, the tapered spiral groove at the other end of the tension balancer 7 will produce a gradually decreasing lifting effect on the enameled wire, thereby ensuring that the winding tension of the enameled wire at the same thickness will not have a significant difference, thereby ensuring that the elongation of the wound enameled wire is the same; After the winding mechanism 2 completes one circle of winding, the enameled wire runs to the other end of the winding roller, and the wire pressing assembly 42 also carries the enameled wire to the end of the one-way screw 41, and the enameled wire is just engaged in the last-stage spiral groove at the end of the tension balancer 7. Then, the servo motor 6 starts to reverse and drives the tension balancer 7 and the one-way screw 41 to reverse, so that the enameled wire returns along the above path in a symmetrical posture. However, the difference is that the enameled wire is wound around the winding roller again in the form of a second layer when it returns, so it passes through the thick The thickness detected by the thickness sensing plate 3 will also change, and when the second layer of enameled wire begins to be wound, the enameled wire coils with increased thickness will synchronously squeeze the thickness sensing plate 3 to move it toward the oil storage chamber 4 by one thickness unit, and the thickness sensing plate 3 will synchronously push the piston plate 33 to move one thickness unit in the oil cavity of the oil storage chamber 4 through the telescopic rod 31, so that the oil corresponding to one thickness unit space inside the oil storage chamber 4 is injected into the pressure regulating chamber 8 through the connecting pipe 9 and the through-type plug rod 81. The tension balancer 7 is wrapped with a limit and the pressure regulating chamber 8 is made of thin-walled rubber (the tension balancer 7 is made of a hard material and cannot be changed), so the outer wall of the pressure regulating chamber 8 will undergo uniform deformation and protrusion in the spiral groove of the tension balancer 7, and the amount of protrusion corresponds exactly to a thickness unit on the winding roller. At the same time, since the enameled wire is in contact with the outer wall of the pressure regulating chamber 8 in the spiral groove, when the pressure regulating chamber 8 protrudes from the spiral groove, the outer wall of the pressure regulating chamber 8 protruding in the spiral groove will further exert an upward force on the enameled wire to adapt to the angle change in another direction brought about by the increase in winding thickness, thereby balancing the winding tension change caused by the angle change in the other direction, thereby achieving further adaptive balance of the enameled wire tension change caused by the increase in winding thickness on the basis of balancing the winding angle, and achieving overall tension balance in the winding process of the enameled wire under the two conditions of winding angle and winding thickness, to ensure that the winding tension of the enameled wire at different thicknesses will not be significantly different, thereby ensuring that the elongation of the wound enameled wire is the same.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
