Description

Technical Field

[0001] This invention relates to the field of generator stator manufacturing technology, specifically to a high-speed flexible wire feeding device. Background Technology

[0002] The automotive industry is currently experiencing rapid growth, with increasing car ownership. Both traditional gasoline-powered vehicles and new energy vehicles involve generator stators, which are primarily composed of an iron core and enameled wire. To meet the high-growth demands of the automotive market, the automation requirements for automotive parts manufacturing are increasing, and the control of labor costs is becoming more stringent. High-speed movement of the enameled wire at different stages of generator stator manufacturing has always been a critical process. The enameled wire of the generator stator is copper wire coated with an insulating and voltage-resistant varnish to ensure the stator's insulation performance. During stator manufacturing, the enameled wire must not be damaged during movement. To improve stator production efficiency, high-speed movement of the enameled wire is necessary. To adapt to rapid changeovers across multiple platforms, rapid switching between flat and round copper wire is required. A single generator stator requires enameled wire of various lengths, necessitating flexible and compatible wire feeding. Traditional motor manufacturing methods, such as cylinder clamping and pushing for wire feeding, cannot meet these requirements. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-speed flexible wire feeding device. This device does not damage the enameled wire and can feed the wire at high speed.

[0004] The objective of this invention is achieved through the following solution: a high-speed flexible wire feeding device, comprising a worktable, a wire feeding base at the upper end of the worktable, and a wire feeding mechanism on the wire feeding base. The wire feeding mechanism includes a motor, a mounting bracket, and a pressing wire feeding mechanism. The mounting bracket is fixedly mounted on the wire feeding base. The motor is connected and fixed to the lower end of the mounting bracket via a motor mounting plate. The motor transmits power to the pressing wire feeding mechanism via a transmission pulley mechanism. The pressing wire feeding mechanism includes two meshing gears at the left and right ends of the front face of the upper end of the mounting bracket. The gears are connected to a drive shaft, the lower end of which is connected to the transmission pulley mechanism. A drive synchronization mechanism is provided at the upper ends of the two gears. The pulley system has two driven shafts on the left and right sides of the rear side of the upper end of the mounting base. A driven synchronous pulley is installed at the upper end of the driven shaft. The driving synchronous pulley and the driven synchronous pulley on the mounting base are connected by a compression feeding synchronous belt. A transition groove is provided between the driven synchronous pulleys on the mounting base, and a front passing groove is provided between the driving synchronous pulleys on the mounting base. The enameled wire passes through the transition groove and extends out from the front passing groove. Adjusting pressure block mechanisms are respectively provided on the inner sides of the left and right compression feeding synchronous belts. By adjusting the pressure block mechanisms, the compression feeding synchronous belt is squeezed towards the middle to clamp the enameled wire. The friction generated by the compression feeding synchronous belt when the driving and driven synchronous pulleys rotate drives the enameled wire to be conveyed.

[0005] The mounting connector includes a first mounting connector and a second mounting connector. The first mounting connector is provided with an active synchronous pulley, and the second mounting connector is provided with a driven synchronous pulley.

[0006] The transmission pulley mechanism includes a driving transmission pulley and a driven transmission pulley. The driving transmission pulley and the driven transmission pulley are connected by a synchronous transmission belt. The driving transmission pulley is fixedly connected to a motor, and the driven transmission pulley is fixedly connected to a driving shaft.

[0007] The adjusting pressure block mechanism includes a pressure block disposed on the upper end of the mounting connection seat and a limiting block disposed on the side of the mounting connection seat. An adjusting screw is disposed on the side of the pressure block, and a limiting platform is disposed at the front end of the adjusting screw. The limiting platform is connected to the limiting block for limiting. After the pressure block is adjusted to the position by the adjusting screw, it is positioned by fastening bolts.

[0008] The transmission pulley mechanism has a transmission synchronous belt tension adjustment screw installed on the side of the drive transmission pulley.

[0009] The motor is connected and fixed to the motor mounting plate via a motor connector.

[0010] The extrusion feeder timing belt is a rubber timing belt.

[0011] The advantage of this invention is that by driving a synchronous belt with a motor, the rubber synchronous belt squeezes the enameled wire, and the friction force achieves the purpose of moving the enameled wire at high speed. This ensures that the enameled wire is not damaged and can adapt to enameled wires of different shapes or other lines. The wire feeding length is controlled by the motor, which can meet the requirements of feeding different lengths of enameled wire. Attached Figure Description

[0013] like Figures 1 to 3As shown, a high-speed flexible wire feeding device includes a workbench 1, with a wire feeding base 2 at the upper end of the workbench 1. A wire feeding mechanism is mounted on the wire feeding base 2, comprising a motor 14, a mounting connector, and a compression wire feeding mechanism. The mounting connector includes a first mounting connector 20 and a second mounting connector 3. A driving synchronous pulley 19 is mounted on the first mounting connector 20, and a driven synchronous pulley 3 is mounted on the second mounting connector 3. The mounting connectors are fixedly mounted on the wire feeding base 2. The motor 14 is connected and fixed to the lower end of the mounting connector via a motor mounting plate 11, and to the motor mounting plate 11 via a motor connector 13. The motor 14 transmits power to the compression wire feeding mechanism via a transmission pulley mechanism, which includes a driving transmission pulley 16 and a driven transmission pulley 21. The driving transmission pulley 16 and the driven transmission pulley 21 are connected by a transmission synchronous belt 15. The driving transmission pulley 16 is fixedly connected to the motor 14, and the driven transmission pulley 21 is fixedly connected to a drive shaft 9. The drive pulley 16 in the transmission pulley mechanism has a transmission synchronous belt tension adjustment screw 12 on its side. The extrusion feeding mechanism includes two meshing gears 17 on the left and right ends of the front side of the upper end face of the mounting connector. The gears 17 are connected to the drive shaft 9, and the lower end of one drive shaft 9 is connected to the transmission pulley mechanism. A drive synchronous pulley 19 is set on the upper end of the two gears 17. Two driven shafts 6 are set on the left and right ends of the rear side of the upper end face of the mounting connector. A driven synchronous pulley 7 is set on the upper end of the driven shaft 6. The drive synchronous pulley 19 and the driven synchronous pulley 7 on the mounting connector are connected by an extrusion feeding synchronous belt 4. A transition groove 5 is set between the driven synchronous pulleys 7 on the mounting connector, and a front through groove 10 is set between the drive synchronous pulleys 19 on the mounting connector. The wire 18 passes through the transition groove 5 and extends from the front groove 10. Adjustable pressure block mechanisms 8 are respectively installed on the inner sides of the left and right extrusion feeding synchronous belts 4. These mechanisms squeeze the extrusion feeding synchronous belts 4 towards the center, clamping the enameled wire 18. Each adjustment pressure block mechanism 8 includes a pressure block 8-1 located at the upper end of the mounting connector and a limiting block 8-3 located on the side of the mounting connector. An adjusting screw 8-2 is located on the side of the pressure block 8-1, and a limiting platform 8-4 is located at the front end of the adjusting screw 8-2. The limiting platform 8-4 is connected to the limiting block 8-3 for positioning. After the pressure block 8-1 is adjusted to its position by the adjusting screw 8-2, it is positioned by the fastening bolt 8-5. The friction generated by the extrusion feeding synchronous belts 4 when the driving synchronous pulley 19 and the driven synchronous pulley 7 rotate drives the enameled wire 18 for transmission. The extrusion feeding synchronous belt 4 is a rubber synchronous belt.

[0014] When the motor is started, power is transmitted to the gears via the transmission belt pulley mechanism. The rotation of the gears drives the active synchronous pulley to rotate, which in turn drives the driven synchronous pulley to rotate via the extrusion feeding synchronous belt. The adjusting screw connected to the pressure block is adjusted, and the limit block limits the adjusting screw. The fastening screw fixes the position of the pressure block, causing the two pressure blocks to move towards the middle to extrude the wire feeding synchronous belt. The extrusion feeding synchronous belt extrudes the enameled wire, and the friction of the extrusion feeding synchronous belt drives the enameled wire to move at high speed.

[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications made to the present invention by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
