Description

Technical Field

[0001] The present invention relates to the technical field of motor processing, and particularly relates to a coil covering device for motor processing. Background Art

[0002] When producing and processing a motor, it is necessary to produce the coil in the motor components. The coil is usually composed of a wire wound around an insulating tube. The coil mainly serves as a conductor inside the motor and can induce an electromotive force or pass an electric current to enable the normal operation of a generator or a motor. After the wire is wound around the coil currently, it is necessary to wind a tape around the insulating tube to achieve the effect of covering the coil. This can effectively prevent the wire from being scratched by the needle when the wire winding is tied. Currently, the covering of the coil in motor processing generally requires manual operation, with low covering efficiency and being not easy to fix, resulting in easy skewing or inaccuracy of the covering. Summary of the Invention

[0003] In order to overcome the disadvantages of generally requiring manual operation, low covering efficiency, and being not easy to fix, resulting in easy skewing or inaccuracy of the covering, the technical problem to be solved is: to provide a coil covering device for motor processing that is easy to clamp and can achieve a more accurate and consistent covering effect.

[0004] The technical solution of the present invention is: a coil covering device for motor processing, including a main frame, a support plate, a top bracket, a sheave lifting mechanism, an opposing clamping mechanism, a fitting mechanism, and a rotating mechanism. A support plate is fixedly installed on the main frame, a top bracket is vertically fixedly installed on the main frame, a sheave lifting mechanism is installed on the main frame and the top bracket, an opposing clamping mechanism is installed on the support plate and the sheave lifting mechanism, a rotating mechanism is provided on the top bracket, and a fitting mechanism is provided on the top bracket and the sheave lifting mechanism.

[0005] In one of the embodiments, the sheave lifting mechanism further includes a servo motor, a power shaft, a sheave ring, a lifting main rod, a lifting four-corner frame, an annular frame, and a vertical rod. The servo motor is fixedly installed on the top bracket, the output shaft of the servo motor is fixedly connected to the power shaft, a sheave ring is fixedly installed at the lower end of the power shaft, the lifting main rod is slidably connected to the main frame and the sheave ring is slidably connected to the lifting main rod, the lower end of the lifting main rod is fixedly connected to the lifting four-corner frame, the annular frame is rotatably installed in the middle of the lifting four-corner frame, and the vertical rod is fixedly installed on the lifting four-corner frame and is slidably connected to the main frame.

[0006] In one embodiment, the opposite clamping mechanism further includes a fixed wedge block, a sliding opposite rod, a movable clamping wheel, and a tension spring. The two sliding opposite rods are slidably mounted on the support plate and are symmetrically arranged. At both ends of the bottom of the lifting four-corner frame close to the sliding opposite rod, fixed wedge blocks are fixedly installed. At one end of the sliding opposite rod, two movable clamping wheels are fixedly installed. A tension spring is fixedly connected between the support plate and the sliding opposite rod, and the fixed wedge block is in contact with the sliding opposite rod.

[0007] In one embodiment, the fitting mechanism includes a fixed concave disk, a movable push disk, a torsion spring I, an L-shaped slotted plate, a fixed guide rod, a vertical round rod, a transverse support plate, a movable rotating bar, a rubber strip placement seat, and a torsion spring II. The fixed concave disk is fixedly connected to the power shaft. The top bracket is rotatably installed with a movable push disk, and a torsion spring I is fixedly connected between the movable push disk and the top bracket. The fixed concave disk and the movable push disk are in contact with each other. The bottom of the movable push disk is slidably installed with an L-shaped slotted plate. The fixed guide rod is fixedly installed on the top bracket. One end of the fixed guide rod is slidably installed with an L-shaped slotted plate. One end of the L-shaped slotted plate is slidably connected with a vertical round rod and the vertical round rod is vertically arranged. The transverse support plate is fixedly installed on the main frame, and a movable rotating bar is rotatably installed on the transverse support plate. The bottom end of the vertical round rod is fixedly connected to the movable rotating bar. The lifting four-corner frame passes through the bottom end of the vertical round rod and the movable rotating bar. A rubber strip placement seat is rotatably installed on the annular frame, and a torsion spring II is fixedly connected between the rubber strip placement seat and the annular frame. The movable rotating bar and the rubber strip placement seat are in contact.

[0008] In one embodiment, the rotating mechanism includes a sector gear, an L-shaped support, a fixed rotating gear, a sliding rotating rod, and a transmission gear. The sector gear is fixedly connected to the power shaft and is located above the fixed concave disk. The L-shaped support is fixedly installed at the bottom of the top bracket. The top bracket is slidably installed with a sliding rotating rod. The sliding rotating rod is slidably installed with a transmission gear. The sector gear and the transmission gear are meshed, and the transmission gear is rotatably connected to the L-shaped support. The bottom end of the sliding rotating rod is fixedly connected to a fixed rotating gear, and the fixed rotating gear is meshed with the annular frame.

[0009] Particularly in one embodiment, a heating rod is further included, and the heating rod is fixedly installed at one end of the rubber strip placement seat.

[0010] The present invention has the following advantages: First, when the lifting four-corner frame moves downward, it drives the fixed wedge blocks at both ends to move downward. The two fixed wedge blocks move downward and push the two sliding opposite rods to move closer to the inside. The two movable clamping wheels will clamp the motor coil that needs to be wrapped with the rubber strip, so that the motor coil can be fixed when being wrapped, making the motor coil centered and conducive to accurate wrapping position.

[0011] Second, when the fixed concave disk rotates clockwise until it contacts the movable push disk, the movable rotating bar rotates and no longer blocks the rubber strip placement seat on the annular frame. The rubber strip placement seat rotates clockwise, causing one end of the adhesive tape pulled out by the rubber strip placement seat to closely adhere to the part of the motor coil that needs to be wrapped with the rubber strip, and the adhesive tape approaches and adheres to the motor coil.

[0012] The fixed concave disk and the sector gear continue to rotate. When the sector gear rotates to mesh with the transmission gear, the transmission gear rotates to drive the fixed rotating gear, the annular frame, and the rubber strip placement seat to rotate counterclockwise. The rubber strip placement seat rotates around the placed motor coil, and the adhesive tape wraps around the surface of the motor coil for sticking.

[0013] Third, after the adhesive tape wraps around the motor coil for one circle and the sticking is completed, the heating rod is manually activated. The heating rod heats up and directly cuts off the part of the rubber strip close to the heating rod. This can cause the rubber strip to be cut off after winding around the motor coil for one circle. Repeating this process in sequence facilitates the surface wrapping treatment of a large number of motor coils and achieves a consistent surface wrapping effect, thereby meeting the quality standards.

The fixed guide rod 65 is fixedly installed on the top bracket 3, and one end of the fixed guide rod 65 is slidably provided with the L-shaped slotted plate 64.

A rubber strip placing seat 69 is rotatably installed on the annular frame 46, and a second torsion spring 610 is fixedly connected between the rubber strip placing seat 69 and the annular frame 46. The movable rotating bar 68 and the rubber strip placing seat 69 are in contact with each other. The rotation of the movable rotating bar 68 can drive the rotation of the rubber strip placing seat 69. The rubber strip placing seat 69 is used for placing rubber strips.

[0032] The rotating mechanism 7 includes a sector gear 71, an L-shaped support 72, a fixed rotating gear 73, a sliding rotating rod 74, and a transmission gear 75. The sector gear 71 is fixedly connected to the power shaft 42 and is located above the fixed concave disk 61. The L-shaped support 72 is fixedly installed at the bottom of the top bracket 3. The top bracket 3 is slidably provided with the sliding rotating rod 74. The sliding rotating rod 74 is slidably provided with the transmission gear 75. The transmission gear 75 can move up and down along the sliding rotating rod 74, and the transmission gear 75 is rotatably connected to the L-shaped support 72. The sector gear 71 and the transmission gear 75 are meshed with each other. The bottom end of the sliding rotating rod 74 is fixedly connected to the fixed rotating gear 73. The fixed rotating gear 73 is meshed with the annular frame 46. The fixed rotating gear 73 is located above the transmission gear 75.

[0033] In actual operation, when the motor coil needs to be wrapped, the motor coil is placed in the middle of the support plate 2, directly below the annular frame 46. The rubber strip is first placed inside the rubber strip placement seat 69 and one end of the rubber strip is pulled to the end of the rubber strip placement seat 69 away from the lifting four-corner frame 45. Initially, the torsion spring II 610 is in a torsion state. At this time, the worker can start the servo motor 41 to rotate clockwise. The servo motor 41 drives the power shaft 42, the fixed concave disk 61, the sector gear 71 and the sheave ring 43 to rotate clockwise. As the sheave ring 43 rotates clockwise, the lifting main rod 44 will move downward on the sheave ring 43. At the same time, the lifting four-corner frame 45, the annular frame 46 and the rubber strip placement seat 69 will move downward to approach the motor coil that needs to be wrapped with the rubber strip. The vertical rod 47 is used to guide the lifting four-corner frame 45. When the lifting four-corner frame 45 moves downward, it drives the fixed wedge blocks 51 at both ends to move downward. The two fixed wedge blocks 51 move downward to push the sliding opposite rods 52 on both sides to move closer to the inside. The two movable clamping wheels 53 will clamp the motor coil that needs to be wrapped with the rubber strip. In this way, the motor coil can be fixed when being wrapped, making the motor coil centered and conducive to accurate wrapping position.

[0034] Then the fixed concave disk 61 rotates clockwise until it contacts the movable push disk 62. The fixed concave disk 61 will drive the movable push disk 62 to rotate a certain angle. The movable push disk 62 will drive the L-shaped slotted plate 64 to move in the direction close to the fixed guide rod 65. When the L-shaped slotted plate 64 moves, it will drive the vertical round rod 66 and the movable rotating bar 68 to rotate counterclockwise. After the movable rotating bar 68 rotates, it no longer blocks the rubber strip placement seat 69 on the annular frame 46. Under the action of the torsion spring II 610, the rubber strip placement seat 69 rotates clockwise, so that one end of the rubber strip pulled out by the rubber strip placement seat 69 closely adheres to the part of the motor coil that needs to be wrapped with the rubber strip, and the rubber strip is close to sticking to the motor coil;

[0035] The fixed concave disk 61 and the sector gear 71 continue to rotate. When the sector gear 71 rotates to mesh with the transmission gear 75, the transmission gear 75 will rotate to drive the fixed rotating gear 73, the annular frame 46 and the rubber strip placement seat 69 to rotate counterclockwise. The rubber strip placement seat 69 will rotate around the placed motor coil, and the rubber strip will be pasted around the surface of the motor coil. When the sector gear 71 rotates until it no longer meshes with the transmission gear 75, at this time, the sliding rotating rod 74, the transmission gear 75, the fixed rotating gear 73, the annular frame 46 and the rubber strip placement seat 69 no longer rotate, and the rubber strip has rotated around the motor coil for one circle and the pasting is completed;

[0036] It also includes a heating rod 8, and the heating rod 8 is fixedly installed at one end of the rubber strip placement seat 69.

[0037] After the gluing is completed, the heating rod 8 is manually activated. The heating rod 8 heats up and directly cuts off the part of the rubber strip close to the heating rod 8. This enables the rubber strip to cut off after winding around the motor coil for one circle. After cutting off the part of the rubber strip close to the heating rod 8, the heating rod 8 is manually turned off. The sheave ring 43 continues to rotate, driving the lifting main rod 44, the vertical rod 47, the lifting four-corner frame 45, the annular frame 46 and the fixed wedge block 51 to rise and reset. The sliding opposing rod 52 resets. When the movable push plate 62 contacts the recess of the fixed concave plate 61, the movable push plate 62 will reset under the elastic force of the torsion spring 63 and drive the L-shaped slotted plate 64, the movable rotating bar 68, the rubber strip placement seat 69 and the vertical round rod 66 to reset. This process repeats in sequence, facilitating the surface wrapping treatment of a large number of motor coils and achieving a consistent wrapping effect, thus meeting the quality standards. After the use of this device, the worker turns off the servo motor 41.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
