Description

Technical Field

[0001] The invention relates to the technical field of mechanical automation, and more specifically to an automatic feeding mechanism for insulating sleeves used in a stator core winding machine. Background Art

[0002] With the development of society, the cost of using workers has increased, and equipment has been improved with automation to replace manual operations. For example, in the production process of motor stators, the stator core needs to be wound, and during the winding process, a section of insulating sleeve needs to be put on the copper wire. This section of insulating sleeve needs to be cut from the coiled insulating sleeve, picked up by a robot or manually, and put on the copper wire.

[0003] Therefore, various unwinding and cutting devices for insulating sleeves have appeared on the market to complete automatic feeding. Such devices automatically unwind the coiled insulating sleeves and cut them into segments with sharp objects. However, ordinary unwinding and cutting devices have simple structures and the following disadvantages: 1. The cut length is uncontrollable, and the lengths of the insulating sleeves in segments are basically the same, which makes them inflexible to use; 2. After the cutting tool makes multiple reciprocating motions, the error increases, and it is easy to loosen and shift, affecting the cutting; 3. The unwinding process of the sleeve is not monitored, and there will be idle cutting, resulting in energy waste and poor overall effect.

[0004] Based on this, the present invention proposes an automatic feeding mechanism for insulating sleeves for a stator core winding machine. Summary of the invention

[0030] The present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figures 1 to 8 As shown, the present embodiment involves an automatic feeding mechanism for insulating sleeves for a stator core winding machine, comprising:

[0032] The adjusting seat body 10 comprises a vertically arranged guide rod 11, the upper end of which is slidably connected to an adjusting platform 12, and the lower end of which is provided with an adjusting base 13. The guide rod 11 is provided with a suspension 14 located below the adjusting platform 12, and the suspension 14 is threadedly connected with an adjusting rod 15 parallel to the axis of the guide rod 11, the upper end of the adjusting rod 15 is connected to the adjusting platform 12, and the lower end is provided with a rotary block 16; the height of the adjusting platform 12 can be changed by rotating the rotary block 16;

[0033] The main conveying mechanism 20 is fixedly connected to the adjustment platform 12, and the main conveying mechanism 20 includes a driving wheel 21, a pressure wheel 22 whose wheel surface is close to the wheel surface of the driving wheel 21, and a motor 23 for controlling the rotation of the driving wheel 21; an insulating sleeve is placed between the driving wheel 21 and the pressure wheel 22, and the driving wheel 21 controls the conveying of the insulating sleeve;

[0034] The cutting mechanism 30 is fixedly connected to the adjustment platform 12 and arranged on one side of the main conveying mechanism 20. The cutting mechanism 30 includes a cutting machine base 31. The cutting machine base 31 is provided with a slide groove 32 with an upward notch. A knife seat 33 is slidably connected in the slide groove 32. The knife seat 33 is provided with a telescopic cylinder 34 for controlling the upward and downward sliding of the knife seat 33. The cutting machine base 31 is provided with a conduit hole 35 located below the slide groove 32. The conduit hole 35 is provided with a blade 36 that slides up and down with the knife seat 33.

[0035] The clamping mechanism 40 is arranged above the outlet of the conduit hole 35 , and comprises an air claw 41 whose claw mouth is perpendicular to the axis of the conduit hole 35 and a telescopic cylinder 42 for controlling the air claw 41 to approach or move away from the axis of the conduit hole 35 .

[0036] In this embodiment, the head end of the coiled insulating sleeve is placed between the driving wheel 21 and the pressure wheel 22 on the main conveying mechanism 20, and passes through the catheter hole 35. Then the motor 23 is operated, the driving wheel 21 rotates, and the insulating sleeve is conveyed. When the insulating sleeve extends out of the catheter hole 35 to a set length, the telescopic cylinder 42 carries the air claw 41 to move downward, and the air claw 41 operates to clamp and position the insulating sleeve extending out of the catheter hole 35. The telescopic cylinder 34 operates, and the knife seat 33 carries the blade 36 to slide downward in the slide groove 32. The blade 36 cuts the insulating sleeve at the opening of the catheter hole 35, completing one sleeve cutting.

[0037] Furthermore, it also includes an auxiliary conveying mechanism 50, which includes a driving wheel 51, a pressure wheel 52 whose wheel surface is close to the driving wheel 51, and a motor 53 for controlling the rotation of the driving wheel 51, so as to pre-loosen the coiled insulating sleeve to facilitate subsequent transportation, thereby ensuring smooth transportation of the insulating sleeve.

[0038] Furthermore, it also includes a pre-delivery detection mechanism 60, which is arranged between the auxiliary conveying mechanism 50 and the main conveying mechanism 20. The pre-delivery detection mechanism 60 includes a detection base 61, a proximity sensor 62 and a pressure rod 63. One end of the pressure rod 63 is hinged to the detection base 61, and the other end is pressed on the insulating sleeve in conveyance. The proximity sensor 62 is arranged below the pressure rod 63. When the insulating sleeve is in the process of conveying, the insulating sleeve is pulled, and the end of the pressure rod 63 that is not hinged to the detection base 61 is lifted up. The proximity sensor 62 receives and feeds back a signal, and this state is the material conveying state; when the insulating sleeve is delivered, the pressure rod 63 falls and presses on the proximity sensor 62. The proximity sensor 62 receives and feeds back a signal, and this state is the material delivery state.

[0039] Furthermore, the cutting machine base 31 is rotatably connected to a guide wheel 37 whose wheel surface protrudes from the side wall of the cutting machine base 31, and the guide wheel 37 is rollingly connected to a guide plate 38 that slides up and down with the knife base 33. The side of the knife base 33 is connected to a guide rod 39 that passes through the guide plate 38, and a nut on the guide rod 39 is connected to a pre-tightening nut 70. The guide rod 39 is also sleeved with a compression spring 71 with one end abutting the guide plate 38 and the other end abutting the pre-tightening nut 70. By rotating the pre-tightening nut 70 toward the guide plate 38, the compression spring 71 is compressed, and the knife base 33 is closer to the guide plate 38, so that the blade 36 fits the cutting machine base 31, which is used to adjust the position of the blade 36. Since the blade 36 for reciprocating cutting will produce errors after long-term use, it is easy to loosen and shift. The above-mentioned components are arranged to adjust the blade 36 and repair the errors.

[0040] Furthermore, a locking nut 72 is threadedly connected to the guide rod 39. Vibration may be generated during the operation of the mechanism, which may easily cause the pre-tightening nut 70 to rotate outward, affecting the cutting of the blade 36. The addition of the locking nut 72 can prevent the pre-tightening nut 70 from loosening.

[0041] Furthermore, a chip receiving groove 73 is provided below the blade 36 for receiving scraps generated during the cutting process of the insulating sleeve; the chip receiving groove 73 is fixedly connected to the adjustment platform 12 and can move up and down with the adjustment platform 12 .

[0042] The present invention realizes automatic tube cutting by changing the rotation speed of the driving wheel, adjusting the sleeve conveying speed, or changing the cutting frequency of the blade, and the tube cutting length is controllable, and the use is flexible and convenient; the insulating sleeve extending out of the catheter hole is clamped and fixed by the clamping mechanism, so that the sleeve can be positioned before tube cutting, which is convenient for cutting and accurate cutting; the blade position is adjusted by rotating the pre-tightening nut to prevent the blade from offsetting due to errors caused by repeated use of the blade, which affects the cutting, and plays a role in adjusting the blade and repairing the error; the coiled insulating sleeve is pre-loosened by the auxiliary conveying mechanism to facilitate subsequent conveying, so that the insulating sleeve is conveyed smoothly; the pre-delivery detection mechanism is set to monitor the conveying state of the sleeve and realize the pre-delivery sensing of the sleeve, and the overall function is perfect and practical.

[0043] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
