Description

Technical Field

[0001] This invention relates to the field of motor coil processing, and more specifically to an automatic winding machine for motor coil winding. Background Technology

[0002] An automatic winding machine is a machine that winds a thread-like object onto a specific workpiece. Commonly used automatic winding machines wind enameled copper wire (for winding inductor coils in electronic and electrical products), textile thread (for winding yarn spools and balls used in textile machines), as well as heating wire for electric heating appliances, solder wire, electrical wire, and cable. Automatic winding machines are also generally needed in the manufacturing process of motor coils. Existing automatic winding machines for motor coils typically use only one winding spool during the winding process. After the coil on the winding spool is wound, the winding spool is removed and a new coil is replaced. Then, the winding spool with the new coil is reinstalled to continue winding. This method has very low winding efficiency. Furthermore, the winding spool is usually clamped manually, which is quite cumbersome. Summary of the Invention

[0013] 1. The present invention discloses an automatic winding machine for motor coil winding, comprising a worktable; a main unit is mounted on one side of the worktable, and a first fixed base is mounted on the other side of the worktable. A rotating shaft is rotatably connected between the main unit and the first fixed base, and a fixed disk assembly is connected to the rotating shaft.

[0031] An automatic winding machine for motor coil winding includes a worktable 1; a main unit 2 is mounted on one side of the worktable 1, and a first fixed base 3 is mounted on the other side; a rotating shaft 4 is rotatably connected between the main unit 2 and the first fixed base 3; a motor for driving the rotating shaft 4 is connected inside the main unit 2; a fixed disk assembly is connected to the rotating shaft 4, and multiple winding shafts 5 rotatably distributed around the axis of the rotating shaft 4 are detachably connected to the fixed disk assembly; specifically, four winding shafts 5 are detachably connected to the fixed disk assembly and evenly distributed around the axis of the rotating shaft 4; specifically, the fixed disk assembly includes a right disk body 21 and a left fixed disk base 22; the outer periphery of the left fixed disk base 22 has a rotating connection groove 23 corresponding to the winding shaft 5; the winding shaft 5 is placed in the rotating connection groove 23 and covered with an upper cover 24; the upper cover 24 is bolted to the left fixed disk base 22, and the winding shaft 5 is rotatably connected to the upper cover 24 and the left fixed disk base 22. Between the fixed plate seats 22, a rotating connecting seat 25 corresponding to the winding shaft 5 is connected to the left side of the right plate body 21. The winding shaft 5 is inserted into the rotating connecting seat 25 and can rotate within the rotating connecting seat 25. In terms of fixing the winding shaft 5 to the fixed plate assembly, one end of the winding shaft 5 is inserted into the rotating connecting seat 25, and the other end of the winding shaft 5 is fixed by the upper cover 24. The upper cover 24 is connected to the left fixed plate seat 22 by bolts, which makes installation and disassembly relatively convenient. More specifically, a limiting outer ring 31 is connected to the outside of the winding shaft 5. The left fixed plate seat 22 and the upper cover 24 are both provided with semi-circular arc-shaped rotating grooves 32 corresponding to the limiting outer ring 31. The limiting outer ring 31 is rotatably connected to the left fixed plate seat 22 and the upper cover 24 in the semi-circular arc-shaped rotating grooves 32. The winding shaft 5 is limited by the cooperation of the limiting outer ring 31 and the semi-circular arc-shaped rotating grooves 32, so that the winding shaft 5 cannot move left or right.

[0032] A coil disc 13 is fixed on the winding shaft 5. A turntable 6 for driving the winding shaft 5 is rotatably connected to the side of the main unit 2. The turntable 6 has two radial grooves 7 symmetrically arranged around its axis. A motor for driving the turntable 6 is connected inside the main unit 2. Clamping blocks 8 for holding the winding shaft 5 are radially slidably connected to both radial grooves 7, and the winding shaft 5 is clamped between the two clamping blocks 8. A second fixed seat 9 is connected to the rear side of the turntable 6. An adjusting screw 10 is rotatably connected to the second fixed seat 9, and two sections with opposite rotation directions are connected to the adjusting screw 10. The threaded section 11 is threadedly connected to the two clamping blocks 8 respectively; a drive motor 12 is also fixed on the second fixed base 9, and the drive motor 12 is connected to the adjusting screw 10; in the clamping of the winding shaft 5, the drive motor 12 drives the adjusting screw 10 to rotate forward and backward, and the adjusting screw 10 controls the two clamping blocks 8 to clamp or loosen the winding shaft 5 while rotating forward and backward. The present invention is controlled by the drive motor 12, which is more convenient; preferably, the drive motor 12 can have a built-in power supply, and the drive motor 12 is powered by the power supply.

[0033] A wire guide frame 14 is laterally slidably connected to the rear side of the workbench 1. Specifically, a transverse slide 61 is connected to the rear side of the workbench 1, and the wire guide frame 14 is laterally slidably connected to the transverse slide 61. A wire guide wheel 15 corresponding to the coil disc 13 is rotatably connected to the wire guide frame 14. A reciprocating device for driving the wire guide frame 14 to move laterally is installed below the wire guide frame 14. Specifically, the reciprocating device includes a reciprocating motor 41, a mounting base 42, and a connecting plate 43 connected to the reciprocating motor 41. A push rod 44 is connected to the outer edge of the connecting plate 43. A connecting plate 45 is connected to the lower side of the wire guide frame 14, and a vertical sliding groove 46 is opened on the connecting plate 45. The mounting base 42 is fixed to the rear side of the workbench 1. The reciprocating motor 41 is mounted on the mounting base 42, and the push rod 44 is inserted into the vertical slide groove 46. By energizing the reciprocating motor 41, the reciprocating motor 41 drives the connecting plate 43 to rotate. The connecting plate 43 then pushes the wire frame 14 to move back and forth left and right through the push rod 44. By setting the reciprocating device, the left and right movement of the wire frame 14 can be controlled, so that the wire is evenly wound on the coil 13. Preferably, a connecting frame 51 is also connected to the upper rear side of the wire frame 14. The connecting frame 51 is connected to the upper wiping cloth layer 52 and the lower wiping cloth layer 53. After the wire is wiped by the upper wiping cloth layer 52 and the lower wiping cloth layer 53, it is guided by the wire wheel 15 and finally wound onto the coil 13.

[0034] Instructions for use: When using this invention, first install four winding shafts 5 on the fixed disk assembly (see reference). Figure 1Next, the winding shaft 5 located below the fixed disk assembly is clamped by two clamping blocks 8. Then, the motor connected to the turntable 6 inside the main unit 2 is turned on, and the turntable 6 starts to rotate, driving the winding shaft 5 connected to it to rotate. The winding shaft 5 begins to wind. When the winding shaft 5 is finished, the two clamping blocks 8 are opened by the drive motor 12, and the winding shaft 5 is released. Then, the motor connected to the rotating shaft 4 inside the main unit 2 is turned on, and the rotating shaft 4 starts to rotate and rotates the unwound winding shaft 5 to the bottom. Then, it is clamped by the two clamping blocks 8, and then the winding is performed again. This process is repeated until the coil disks 13 on all four winding shafts 5 are finished winding. Finally, the four winding shafts 5 are removed after winding and replaced with new unwound coil disks 13.
