[0011]
[0011] The wire outlet frame includes a base 3 and a cover plate (not shown in the figure). The cover plate covers above the base 3. Half wire grooves 30 are provided on both the base 3 and the cover plate. The half wire grooves 30 extend along a straight line. The two half wire grooves 30 on the base 3 and the cover plate face each other directly and together form a wire outlet hole. The enameled wire passes through the wire outlet hole. The base 3 has a mounting groove 301 on one side of the half wire groove 30. A sliding plate 31 is provided in the mounting groove 301 and can move back and forth relative to the base 3. A pair of rotatable rollers 35 are provided on the upper and lower parts of the base 3 respectively. The two rollers of each pair of rollers are on both sides of the half wire groove 30 respectively, and the outer edges of the rollers are in the half wire groove 30. Two rollers 35 on the left side of the half wire groove 30 are mounted on the base 3, and the two rollers on the right side are mounted on the sliding plate 31 and can move together with the sliding plate 31. By moving the sliding plate 31, the distance between the two paired rollers 35 can be adjusted. The enameled wire 90 passes through the half wire groove 30, and the rollers 35 press on the enameled wire to straighten the enameled wire and improve the winding quality; during the wire walking process of the enameled wire, the rollers roll, which can reduce the friction between the enameled wire and the rollers, and the wire walking is very stable and smooth; the rollers can also clamp and lock the enameled wire to prevent the enameled wire from falling out of the wire outlet frame when the enameled wire is cut short after the coil winding is completed, so as to facilitate the winding of the next coil and improve the coil winding efficiency.
[0012] The installation groove 301 is provided with a placement hole on the wall surface close to the semi-wire groove 30. The first spring 32 is placed in the placement hole under compression, and its two ends are respectively pressed against the bottom wall of the placement hole and the sliding plate 31. The sliding plate 31 has a guide rod which is inserted into the placement hole. The installation groove 301 is provided with a through threaded hole on the wall surface far from the semi-wire groove 30. The sliding plate 31 is provided with a receiving hole at a position directly opposite to the threaded hole. The second spring 33 is placed in the receiving hole. The bolt 34 is screwed into the threaded hole and the receiving hole from the outside of the base 3 and presses on the second spring 33. By rotating the bolt 34, the sliding plate 31 can be moved to adjust the distance between the two paired rollers, so as to lock the enameled wire or adapt to enameled wires of different diameters. During the wire routing process, the sliding plate 31 is in an elastically adjustable state between the two springs, which can make the wire routing smoother and more stable.
[0013] Both ends of the bottom coil 9 of the ignition coil are respectively docked with the right connector 22 and the left connector 23. The wire outlet frame is fixedly installed on the frame. The enameled wire passes through the wire outlet frame and then winds around the bottom coil 9 of the ignition coil, and the wire outlet position is fixed. The winding motor 21 is started to rotate the right connector 22. The right connector 22 drives the bottom coil 9 and the left connector 23 to rotate together, so that the enameled wire is wound around the bottom coil 9. While winding the wire, the motor 32 drives the lead screw 31 to rotate, and the moving frame 2 moves along the lead screw 31. The bottom coil 9 and the moving plate 24 move together with the moving frame 2. The bottom coil 9 rotates and winds the wire while moving axially. By moving the bottom coil to find the winding position accurately, the windings on the bottom coil 9 can be arranged sequentially along the axis of the bottom coil very evenly, and the winding quality is good.
[0014] See Figure 3 , the tape wrapping device includes a tape roll 8, a baffle 6, a tape pressing and cutting device, and a tape feeding device arranged on the frame 1. The tape roll 8 can rotate on the frame 1. The baffle 6 is fixedly installed below the tape roll 8. The tape pressing and cutting device is below the baffle 6. The tape pressing and cutting device and the tape feeding device are respectively on both sides of the baffle 6. The right connector 22 is below the baffle 6 and is on the same side of the baffle 6 as the tape feeding device.
[0015] The glue pressing and cutting device is located below the baffle 6 and includes a sliding plate 41, a moving cylinder 42, a pressing roller 45, a cutting cylinder 43 and a cutting knife 44. The sliding plate 41 is movably arranged on the frame 1 and can move along a direction perpendicular to the baffle 6 to change its distance from the baffle. The moving cylinder 42 is installed on the frame 1, and its push rod is connected to the sliding plate 41 for driving the sliding plate 41 to move. A pressing roller 45 and a cutting cylinder 43 are installed on the sliding plate 41. The pressing roller 45 is at a position opposite to the bottom roll 9. The cutting knife 44 is installed on the push rod of the cutting cylinder 43 and above the pressing roller 45. The cutting cylinder is used to drive the cutting knife to move back and forth in the axial direction of the tape roll. The pressing roller 45 and the cutting knife 44 are on the side of the sliding plate close to the baffle. Through the sliding plate 41, the pressing roller 45 and the cutting knife 44 can extend to the other side of the baffle 6.
[0016] The glue feeding device includes a glue feeding roller 51, a glue feeding cylinder 52, a lifting plate 53 and a lifting cylinder 55. The lifting cylinder 55 is installed on the frame 1, and its push rod end is installed with a lifting plate 53. The lifting plate 53 is pushed up and down by the lifting cylinder 55. The glue feeding cylinder 52 is installed on the lifting plate 54 and moves up and down together with the lifting plate 54. The glue feeding roller 51 is arranged on the push rod of the glue feeding cylinder 52, and the glue feeding cylinder 52 drives the glue feeding roller 51 to move back and forth. The glue feeding roller 51 is at a position opposite to the baffle 6 and can be pressed onto the baffle 6 by moving.
[0017] After the winding of the coil on the bottom coil 9 is completed, the bottom coil 9 has been moved to the position for wrapping the insulating tape below the baffle 6. First, pull the end of the insulating tape wound on the tape roll 8 to a position slightly below the bottom coil 9 of the ignition coil, start the moving cylinder 42, and push the pressure roller 45 and the tape cutting knife 44 together towards the baffle 6. The pressure roller 45 and the tape cutting knife 44 move together to the other side of the baffle 6. The pressure roller 45 presses the insulating tape 81 against the bottom coil 9, so that the insulating tape 81 adheres to the coil already wound on the bottom coil 9. At this time, the tape cutting knife 44 is at the outer position of the edge of the insulating tape 81 and will not cut the insulating tape 81. Then the pressure roller 45 and the tape cutting knife 44 retreat together, and the pressure roller 45 leaves the insulating tape 81. The bottom coil 9 rotates to wrap the insulating tape 81 around the coil already wound on the bottom coil 9. After the wrapping is completed, the bottom coil 9 stops rotating. The tape feeding cylinder 52 drives the tape feeding roller 51 to move towards the baffle 6, pressing the insulating tape 81 in front of the baffle against the baffle 6. The tape feeding roller 51 and the baffle 6 temporarily fix the insulating tape 81 together above. While the tape feeding roller 51 is moving, the pressure roller 45 and the tape cutting knife 44 also move together towards the bottom coil 9. The pressure roller 45 presses on the insulating tape 81 and the bottom coil 9, and the pressure roller 45 and the bottom coil 9 temporarily fix the insulating tape 81 together below. The tape cutting knife 44 is between the tape feeding roller 51 and the pressure roller 45. Start the tape cutting cylinder 43, and the tape cutting knife 44 cuts off the insulating tape 81, and the tape cutting cylinder 43 stops. Then the pressure roller 45 and the tape cutting knife 44 retreat together. The right connector 22 and the left connector 23 bring the bottom coil 9 wrapped with the insulating tape back to the winding position, wind the coil on the outside of the insulating tape at the winding position. After the winding of the coil is completed, the bottom coil 9 is taken off and a new bottom coil is replaced. After the winding of the new bottom coil 9 is completed, it is moved to the position for wrapping the insulating tape below the baffle 6. The tape feeding cylinder 52 moves downward to send the end of the insulating tape 81 to a position slightly below the bottom coil 9. The pressure roller 45 moves towards the bottom coil 9, pressing the insulating tape 81 against the bottom coil 9, so that the insulating tape 81 adheres to the coil already wound on the bottom coil 9. Then the tape feeding roller 51 retreats, leaving the insulating tape 81, and at the same time the tape feeding cylinder 52 moves upward. After the tape feeding roller 51 leaves the insulating tape 81, the pressure roller 45 and the tape cutting knife 44 retreat together, and the pressure roller 45 leaves the insulating tape 81. The bottom coil 9 rotates to start wrapping the insulating tape 81 around the coil already wound on the bottom coil 9.
[0018] The present invention can automatically complete the winding of the coil and wrap the insulating tape on the wound coil, with a high degree of automation, greatly improving the production efficiency, and having good effects on the winding of the coil and the wrapping of the insulating tape.
