Abstract

A winding mechanism with a coil pin protection device includes a machine, a winding assembly, and a pin protection assembly. The winding assembly includes a jig and a block. The pin protection assembly includes a two-axis moving device, a mounting plate, a guide rail, a slide, a pulley, an extension block, and a protection block. The extension block is arranged at one end of the slide close to the winding assembly. When winding, the extension block passes through the block, so that when the winding assembly continuously rotates clockwise and counterclockwise for winding, it will drive the slider to move back and forth along the guide rail, thereby ensuring that the protection block always rotates synchronously with the pin of the coil skeleton. Two protection blocks are located on both sides of the pin, and a wire groove is provided on the protection block. When winding, the wire will pass through the wire groove and the pin, and the pulling force applied to the wire during winding acts on the wire groove, thereby avoiding stress on the pin and preventing the pin from deformation.

[0002] A coil usually refers to a ring-shaped wire winding. The most common coil applications include motors, inductors, transformers, and loop antennas. Generally, the wires are wound one by one, and the wires are insulated from each other. When winding the coil, it needs to be placed in a jig, and then the jig is driven by a motor to rotate and the wire is wound around the coil skeleton with the help of a guide pin. The coil skeleton in the prior art is provided with a plurality of pins, and the pins are V-shaped. When winding, it is necessary to first clamp the starting wire at the opening of the pins, and then insert the wire into the coil skeleton for winding. Since the wire is constantly pulled during winding, it is easy to bend the pins of thicker diameter wires during winding, causing the pins to deform and affect product quality. Summary of the Invention

[0018] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0019] like Figures 1 to 5 , which is a schematic structural diagram of a winding mechanism with a coil pin protection device provided by the present invention. The winding mechanism with a coil pin protection device includes a machine platform 10, a winding assembly 20 disposed on the machine platform 10, and a plurality of pin protection assemblies 30 disposed on the machine platform 10. It is conceivable that the winding mechanism with a coil pin protection device also includes other functional modules, such as connection components, sensors, and mounting components, etc. These are well known to those skilled in the art and will not be described in detail here.

[0020] First, it should be noted that the winding mechanism with the coil pin protection device is used to wind the coil bobbin 100. The coil bobbin 100 is provided with a plurality of V-shaped pins 110. When winding, the wire needs to be clamped at the opening of the pins 110 and then inserted into the coil bobbin 100 for winding. The coil bobbin 100 should be prior art and will not be described in detail here.

[0021] The machine 10 is used to carry the above-mentioned functional modules, so the machine 10 is provided with a variety of functional structures, such as screws, bolts, clamps, etc. to complete the installation and assembly of the above-mentioned functional modules. They can be set according to actual needs and will not be described in detail here.

[0022] The winding assembly 20 includes a motor 21 , a fixture 22 disposed on the motor 21 , three locking assemblies 23 disposed on the fixture 22 , and three stoppers 24 disposed on the fixture 22 .

[0023] The motor 21 is used to drive the jig 22 to rotate to cooperate with the guide needle winding. The jig 22 is cylindrical. Three rectangular through holes 25 are circumferentially spaced on the outer wall of the jig 22. The rectangular through holes 25 are used to pass the locking assembly 23.

[0024] The locking assembly 23 includes a U-shaped bracket 231 mounted on the outer wall of the jig 22, a rotating rod 232 rotatably mounted on the U-shaped bracket 231, a spring 233 mounted at one end of the rotating rod 232, and a locking block 234 mounted at the other end of the rotating rod 232. The middle portion of the rotating rod 232 is rotatably connected to the U-shaped bracket 231 via a rotating shaft. The locking block 234 is rotatably mounted at one end of the rotating rod 232, and the spring 233 is mounted at the other end. One end of the spring 233 is connected to the outer wall of the jig 22, and the other end is connected to one end of the rotating rod 232. The locking block 234 is movably inserted into the rectangular through-hole 25, with one end rotatably connected to the rotating rod 232. The other end, facing the coil bobbin 100, is formed into a circular groove, thereby better conforming to the shape of the coil bobbin 100 and providing a more secure lock. The elastic force of the spring 233 always presses against one end of the rotating rod 232, so that the rotating rod 232 rotates and pushes the locking block 234 on the other end toward the coil frame 100, thereby pressing against the coil frame 100 to achieve locking.

[0025] The stopper 24 is disposed on the end surface of the jig 22 and is positioned corresponding to the pin 110 of the coil bobbin 100. The stopper 24 has a U-shaped structure and is used to pass through the pin guard assembly 30. At the same time, it drives the pin guard assembly 30 to move when the jig 22 rotates. The specific description will be given below in conjunction with the pin guard assembly 30.

[0026] The pin protection assembly 30 includes a two-axis moving device 31 arranged on the machine 10, a mounting plate 32 arranged on the two-axis moving device 31, a guide rail 33 arranged on the mounting plate 32, a slide 34 arranged on the guide rail 33, four pulleys 35 arranged on the slide 34, an induction assembly 36 arranged on the mounting plate 32, an extension block 37 arranged on the slide 34, two protection blocks 38 arranged at intervals on the extension block 37, and a zeroing assembly 39 arranged on the two-axis moving device 31.

[0027] The two-axis moving device 31 is used to drive the other components of the pin protection assembly 30 to move in the vertical direction and in the direction close to or away from the winding assembly 20, so as to control the extension block 37 to pass through the stop block 24 and approach the pin 110 of the coil skeleton 100. The guide rail 33 has an arc-shaped structure and its opening direction is toward the winding assembly 20. The guide rail 33 is used to support the slide 34 and the pulley 35 to slide along the guide rail 33. The arc shape of the guide rail 33 can make the movement direction of the slide 34 and the pulley 35 the same as the rotation direction of the winding assembly 20 when winding. The pulley 35 is located on the end face of the slide 34 facing the guide rail 33. The four pulleys 35 are respectively arranged on both sides of the guide rail 33 in pairs and are rotatably connected to the slide 34 at the center. The pulley 35 can slide along the guide rail 33, thereby driving the slide 34 to move together.

[0028] The sensing assembly 36 includes a sensor 361 disposed on the mounting plate 32 and a sensing block 362 disposed on the slide 34. When the slide 34 moves along the guide rail 33, the sensing block 362 is driven past the sensor 361, thereby sensing the number of reciprocating movements.

[0029] The extension block 37 is provided at one end of the slide plate 34 near the winding assembly 20, and the size of the extension block 37 is the same as the opening size of the stop block 24. The sliding power of the slide plate 34 comes from the rotation of the winding assembly 20. During winding, the extension block 37 passes through the stop block 24. When the winding assembly 20 continuously rotates clockwise and counterclockwise for winding, it drives the stop block 24 to move together, and the stop block 24 drives the extension block 37 to move together, thereby driving the slide plate 34 to reciprocate along the guide rail 33, thereby ensuring that the protection block 38 always rotates synchronously with the pins 110 of the coil bobbin 100, thereby better protecting the pins 110.

[0030] The protective blocks 38 are spaced apart so that they can be located on either side of the pin 110. A wire slot 381 is provided on the protective block 38. During winding, the wire passes through the slot 381 and the pin 110. Because the slot 381 is fixed in position, any pulling force applied to the wire during winding is applied to the slot 381, thereby protecting the pin 110 from stress and preventing deformation. After winding is completed, the protective block 38 moves downward to free the wire from the slot 381. The opening of the pin 110 is then manually or mechanically closed, completing the winding process.

[0031] The zeroing component 39 includes a positioning shaft 391 provided on the two-axis moving device 31, and a U-shaped plate 392 provided on the slide 34. The positioning shaft 391 is vertically provided on the horizontal moving device of the two-axis moving device 31, that is, the positioning shaft 391 can only move horizontally but not vertically. The U-shaped plate 392 is located at one end of the slide 34 close to the positioning shaft 391. The positioning shaft 391 is inserted into the U-shaped plate 392. When winding is required, the two-axis moving device 31 will drive the U-shaped plate 392 and the slide 3434 to rise, thereby disengaging the U-shaped plate 392 from the positioning shaft 391. When winding is completed, the jig 22 will reset each time, that is, rotate to the position before winding. Since the rotation of the jig 22 will drive the slide 34 to move together through the stop block 24. When the jig 22 is reset, the slide 34 and the U-shaped plate 392 will also return to their initial positions, that is, the U-shaped plate 392 is aligned with the positioning shaft 391. Then the two-axis moving device 31 will drive the U-shaped plate 392 and the slide 34 to descend, so that the positioning shaft 391 is reinserted into the U-shaped plate 392, and the pin guard assembly 30 returns to its starting position.

[0032] Compared to the prior art, the winding mechanism provided by the present invention, which features a coil pin 110 protection device, utilizes a slide plate 34 that is slidably positioned on the curved guide rail 33. An extension block 37 is positioned on the end of the slide plate 34 proximal to the winding assembly 20. The stop block 24 is positioned on the jig 22, and the extension block 37 is the same size as the opening of the stop block 24. During winding, the extension block 37 passes through the stop block 24. As the winding assembly 20 rotates clockwise and counterclockwise, it drives the slide plate 34 to reciprocate along the guide rail 33, thereby ensuring that the protection block 38 always rotates synchronously with the pin 110 of the coil bobbin 100. The protection blocks 38 are spaced apart and located on either side of the pin 110. The protection block 38 is provided with a wire groove 381. When winding the wire, the wire will pass through the wire groove 381 and the pin 110. The pulling force exerted on the wire during winding acts on the wire groove 381, thereby avoiding the pin 110 from being subjected to force and preventing the pin 110 from being deformed.
