Technical Field
[0001] This utility model relates to the field of machinery, specifically a wire introduction and lead-out structure for a winding machine for small coils. Background Technology
[0002] With the development of electronic technology, the application of coils has become increasingly numerous and precise. Especially for coils with two parallel wires, previously single-wire winding machines were often used, inevitably leading to fatal defects such as wire crossing, broken leads, and damaged connecting wires. Winding machines using the parallel wire method require two sets of wire feeding devices, corresponding to the two wire nozzles on the left and right arms respectively. After the initial connecting wires (connecting wires refer to the terminals where the wire nozzles wind the coil frame) are completed using the two nozzles on the left arm, to ensure the conductor forms a 90-degree bend, such as... Figure 5 As mentioned above, it is necessary to use the left arm wire nozzle as a stop, and the two wire nozzles of the right arm respectively wrap around the left arm wire nozzle to form a 90-degree angle. However, the wire in the distance between the terminal and the coil frame is generally not close to the coil, which will affect the subsequent winding.
[0003] Similarly, when fitting the leads during the final stage after the coil winding is complete, the conductor also needs to be bent at a 90-degree angle, such as... Figure 6 As shown, the existing technology uses a bent hook to pull the wire, making it form a 90-degree angle, which can easily damage the insulation layer of the wire;
[0004] To prevent the distance between the two wire tips from being too small and interfering with the terminals of the coil frame, it is often necessary to adjust the distance between the two wire tips to be greater than the width of the coil frame. Utility Model Content
[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a right-angle lead-in and lead-out structure for a double-wire winding machine. A pressing head is provided on the left arm of the wire nozzle, and the pressing head is located on the side of the left arm wire nozzle. A stepped shaft is provided at the upper end of the pressing head, and the stepped shaft is inserted into the positioning hole of the left arm wire nozzle. Then, a pin is inserted in the direction perpendicular to the stepped shaft. A hemispherical flexible head is provided at the lower end of the pressing head, and a protrusion is provided at the uppermost end of the flexible head. The protrusion is inserted into the fixing hole at the lower end of the pressing head.
[0006] The left arm is also equipped with a shearing arm and a tape arm. The shearing arm is equipped with scissors, a shearing clamp, and a wire guide rod. The purpose of the wire guide rod is to ensure that the wire ends are at a consistent angle after leg fitting, which facilitates cutting and ensures the quality of the coil. The tape arm is equipped with a wire guide rod on the side facing the coil.
[0007] An adhesive layer is provided between the protrusion and the fixing hole.
[0008] To prevent interference during leg fitting, the distance between the wire lever and the adjacent shear is greater than the width of the coil; the distance between the pressing head and the adjacent wire nozzle is greater than the width of the coil.
[0009] The advantages of this invention are: the use of a pressing head ensures the close contact between the wire and the coil, thus guaranteeing the winding quality; the addition of a wire-pulling rod ensures the accuracy of the relative position of the shears and the wire during cutting; and the straight wire-pulling rod can overcome the damage to the wire caused by the bent wire-pulling rod.

Detailed Implementation
[0018] The present invention will now be described in detail with reference to the accompanying drawings. As shown in the drawings, the double-wire winding machine includes a right arm 1, a left arm 2, a wire feeding device 3, a coil conveying device 4, and a coil support 6. Both the left arm 2 and the right arm 1 include an X-axis support in the front-to-back direction, a Y-axis support in the left-to-right direction, and a Z-axis support in the up-down direction. The Z-axis support is mounted on the Y-axis support, and the Y-axis support is mounted on the X-axis support. For example, the right arm X-axis support 11 is fixed in the right arm X-axis slide rail 112, and the right arm X-axis support 11 cooperates with the right arm X-axis lead screw 111 through a nut. When the right arm X-axis lead screw 111 is driven by a servo motor, the right arm X-axis support can slide back and forth. Similarly, the right arm Y-axis support 12 moves in the left-to-right direction under the drive of the right arm Y-axis lead screw 121, and the right arm Z-axis support 13 moves in the up-down direction under the drive of the right arm Z-axis lead screw.
[0019] The right arm Y-axis support 12 is mounted on the right arm X-axis support 11, and the right arm Z-axis support 13 is mounted on the right arm Y-axis support 12. This structure enables three-dimensional movement of the right arm.
[0020] The rear end of the right arm wire nozzle arm 14 is connected to the wire nozzle arm motor, and the front end of the right arm wire nozzle arm is equipped with two wire nozzles, namely right arm wire nozzle one 101 and right arm wire nozzle two 102.
[0021] The three-dimensional motion drive structure of the left arm 2 is the same as that of the right arm. The difference is that the left arm has two line nozzles corresponding to the right arm, namely the left arm line nozzle one 201 and the left arm line nozzle two 202, and also has a pressing tentacle 203.
[0022] The left arm 2 is also equipped with a shearing arm 25 and a tape arm 27. The shearing arm is equipped with scissors 251, a shearing clamp 252 and a wire guide rod 251. The purpose of setting the wire guide rod is to ensure that the angle of the wire end after the leg is matched is consistent, which facilitates cutting and ensures the quality of the coil.
[0023] The wire feeding device 3 includes a support 34, and a nut is fixed in the part of the support 34 located in the slide rail 35. The lead screw 36 cooperates with the nut. The nuts of the left and right sets of wire feeding devices rotate in opposite directions. The lead screw 36 is connected to the output shaft of the lead screw motor 37.
[0024] A wire feeding pipe 32 is fixed above the support 34. A set of wire feeding wheels 33 is set at the upper end of the wire feeding pipe. After the wire is output from the wire wheel 31 and clamped by the wire feeding wheel, it is fed through the wire feeding pipe 32 to the two wire nozzles of the right arm and the two wire feeding nozzles of the left arm, and then to the wire clamp of the left arm.
[0025] The output end of the cable delivery tube is provided with a tapered section, and correspondingly, the two cable nozzles on the right arm are also provided with tapered grooves.
[0026] The wire clamp 203 is located on the back of the wire nozzle on the left arm. The movable end of the wire clamp is connected to the cylinder piston. The movement of the cylinder piston ensures the opening and closing of the movable end and the fixed end of the wire clamp.
[0027] A pressing head 204 is provided on the left arm thread nozzle 24, and the pressing head 204 is located on the side of the left arm thread nozzle 202; a stepped shaft 2043 is provided at the upper end of the pressing head 204, the stepped shaft is inserted into the positioning hole of the left arm thread nozzle, and then a pin 2042 is inserted in the direction perpendicular to the stepped shaft; a hemispherical flexible head 2041 is provided at the lower end of the pressing head, and a protrusion 2044 is provided at the uppermost end of the flexible head, the protrusion is inserted into the fixing hole at the lower end of the pressing head;
[0028] After the left arm wire nozzle 1 201 and the left arm wire nozzle 2 202 complete the initial leg matching, the left arm drives the left arm wire nozzle 1 201 to bend the two wires that are still passing through the right arm wire nozzle 1 and the right arm wire nozzle 2 to 90° respectively. Then the left arm drives the pressing head 204 to press the wires between the terminal and the coil to ensure that the wires are in close contact with the coil frame.
[0029] The left arm 2 is also equipped with a shearing arm 25 and a tape arm 27. The shearing arm is equipped with scissors 251, a shearing clamp 252, and a wire guide rod 251. The purpose of the wire guide rod is to ensure that the angle of the wire ends after leg fitting is consistent, which facilitates cutting and ensures the quality of the coil. The tape arm has a wire guide rod on the side facing the coil. At the end of the winding stage, the wire guide rod will move closer to the two wires. The wire feed wheel of one of the wires will further feed the wire, causing the originally taut wire to be released. The wire will spring up under its own elasticity, interfering with the position of the wire guide rod. At the same time, the wire end of the right arm passing through the wire will be finally leg-fitted, forming a 90° bend. The other wire will be operated in the same way.
[0030] An adhesive layer is provided between the protrusion and the fixing hole.
[0031] To prevent interference during lead fitting, the distance between the lead lever and the adjacent shear is greater than the width of the coil. Similarly, the distance between the pressing head and the adjacent lead tip is greater than the width of the coil.
[0032] Each motor in this invention is connected to the control center. The computer in the control center controls the working status and parameters of each motor through the controller according to the preset parameters. Through the orderly movement of the left and right arms and each component, they cooperate with each other to achieve the technical effect of this invention.
