Description

Technical Field

[0001] The invention belongs to the field of motor manufacturing. Background Art

[0002] The coil rotor coil frame of the motor needs to arrange insulating paper in the winding slot before the winding process. The insulating paper has excellent insulation performance. It can form an isolation layer between the winding and the coil frame iron core, improve the insulation strength of the winding, reduce discharge, and thus extend the service life of the motor;

[0003] In order to avoid the coil from falling off, Figure 2 and 7 As shown, in a general coil frame structure, the end of the winding slot 20 away from the slot bottom surface 10.2 generally forms a narrow opening 200 whose width is smaller than the inner slot width of the winding slot 20. The structure of the narrow opening 200 prevents the insulating paper from smoothly entering the winding slot 20 along the radial direction of the coil frame;

[0004] Therefore, the existing insulating paper installation methods all adopt the paper insertion process of inserting from the end of the winding groove 20. This end paper insertion process requires that the insulating paper is not easy to deform, is pre-shaped, and is in a hard non-flexible form. This results in certain requirements for the thickness and material of the insulating paper. If the insulating paper is too thick, the heat transfer efficiency will be reduced, which in turn will seriously affect the heat dissipation of the coil flexure group. The too hard material will cause the risk of wear on the insulation skin of the coil.

[0005] Therefore, it is necessary to develop a process for installing ultra-thin flexible insulating paper based on materials such as polyester film on the motor rotor coil frame. Summary of the invention

The rotor coil frame 6 that has not been wound can be installed on a clamp device. The outer circumference of the rotor coil frame 6 is distributed with a plurality of winding grooves 20 in a circumferential array. Each winding groove 20 includes a groove bottom surface 10.2 and two groove side surfaces 10.1. The end of the winding groove 20 away from the groove bottom surface 10.2 forms a narrowed opening 200 with a width smaller than the internal groove width of the winding groove 20; in general processes, the structure of the narrowed opening 200 prevents the insulating paper from smoothly entering the winding groove 20 along the radial direction of the coil frame.

[0043] The core structure of this solution includes a flexible insulation paper installation device, such as Figure 1 and 3 As shown, the flexible insulating paper installation device includes an insulating paper bending platform 8 and a flexible insulating paper installation actuator 1; Figure 3 , 14 , 15, 16; the flexible insulating paper installation actuator 1 includes a mechanical arm 15 capable of horizontal displacement movement, an insulating paper adsorption plate 10 and a two-phase air pump 13; the lower part of the mechanical arm 15 is connected to the transverse strip insulating paper adsorption plate 10 through a lifter 14; the mechanical arm 15 can drive the insulating paper adsorption plate 10 to translate to the insulating paper bending platform 8 and directly above the unwound rotor coil frame 6.

[0044] The thickness of the insulating paper adsorption plate 10 is narrower than the width of the narrowing opening 200 on the rotor coil frame 6; Figure 7 and 8 As shown; the insulating paper adsorption plate 10 can be inserted downward into the winding groove 20 through a narrowed opening 200 on the rotor coil frame 6 under the drive of the lifter 14.

[0045] like Fig.15 The interior of the insulating paper adsorption plate body 10 is an empty space 31 in the plate; the two-phase air pump 13 is on the insulating paper adsorption plate body 10, and the two-phase air pump 13 is also called a bidirectional pump. The two-phase air pump 13 is connected to the empty space 31 in the plate through the air duct 13a; the two-phase air pump 13 is a common compression pump that realizes suction and exhaust by alternately compressing and releasing gas; it can realize forward and reverse operations. When rotating forward, the two-phase air pump 13 continuously sucks away the air in the empty space 31 in the plate through the air duct 13a to form a negative pressure; when reversing, the two-phase air pump 13 presses the external gas into the empty space 31 in the plate through the air duct 13a to form a positive pressure.

[0046] like Fig.14 , 15, 16; also includes an elastic expansion skin 11 bent in a U shape, the elastic expansion skin 11 is made of latex or soft rubber material, the elastic expansion skin 11 covers the lower part of the insulating paper adsorption plate 10, and the contour edge of the inner side of the elastic expansion skin 11 bent in a U shape is fixed to the surface of the insulating paper adsorption plate 10 through a closed-loop sealing belt 11a and sealed and glued; the lower part of the insulating paper adsorption plate 10 covered by the elastic expansion skin 11 is recorded as the plate surface covered part 10a, and the upper part of the insulating paper adsorption plate 10 is not covered by the elastic expansion skin The portion covered by the expansion skin 11 is recorded as the exposed portion 10b of the plate surface; both side surfaces of the covered portion 10a of the plate surface are hollowed out with a number of ventilation holes 140 connected to the empty space 31 in the plate; both sides of the exposed portion 10b of the plate surface are arrayed along the length direction with a number of one-way air guide holes 12 connected to the empty space 31 in the plate, and each one-way air guide hole 12 is provided with a one-way valve. Under the action of the one-way valve, external air can enter the empty space 31 in the plate through the one-way air guide hole 12, while the air in the empty space 31 in the plate cannot be discharged to the outside through the one-way air guide holes 12.

[0047] like Figure 3 , 4 , 5, 6; a flat flexible insulating paper 9a, such as a flexible polyester film, can be placed horizontally on the upper surface of the insulating paper bending platform 8, and a concave paper bending guide groove 7 is provided in the center of the insulating paper bending platform 8. The inner wall of the paper bending guide groove 7 is a smooth inner wall, and the groove width of the paper bending guide groove 7 is slightly wider than the thickness of the insulating paper adsorption plate 10, which is about 0.5 mm wider. At the same time, the upper edge of the paper bending guide groove 7 is provided with an arc transition, so that the insulating paper adsorption plate 10 can be smoothly inserted downward into the paper bending guide groove 7; when a flat flexible insulating paper 9a is placed horizontally on the upper surface of the insulating paper bending platform 8, the insulating paper adsorption plate 10 is inserted downward During the process of paper bending guide groove 7, flexible insulating paper 9a is bent in U shape under the downward pressure of insulating paper adsorption plate 10 and sinks into paper bending guide groove 7 to form U-shaped insulating paper 9, and the left vertical section 9.1, the right vertical section 9.2 and the bottom section 9.3 of the U-shaped insulating paper 9 are respectively attached to the left side, the right side and the bottom surface of the insulating paper adsorption plate 10, and the upper parts of the left vertical section 9.1 and the right vertical section 9.2 of the paper respectively cover a plurality of one-way air guide holes 12 on the left and right sides of the insulating paper adsorption plate 10; glue sprayers 54 are arranged on both sides above the paper bending guide groove 7, and the glue sprayers 54 can spray out mist epoxy resin glue.

[0048] Working principle of installing any piece of flexible insulation paper:

[0049] Step 1: Place a flat flexible insulating paper 9a horizontally on the upper surface of the insulating paper bending platform 8. At the same time, the mechanical arm 15 drives the insulating paper adsorption plate 10 below to move to the top of the paper bending guide groove 7. Figure 3 and Figure 4 .

[0050] Step 2: The insulating paper adsorption plate 10 is driven down by the lifter 14. Since the inner wall of the paper bending guide groove 7 is a smooth inner wall, and the groove width of the paper bending guide groove 7 is slightly wider than the thickness of the insulating paper adsorption plate 10, the insulating paper adsorption plate 10 can be smoothly inserted downward into the paper bending guide groove 7; in the process of inserting the insulating paper adsorption plate 10 downward into the paper bending guide groove 7, the flexible insulating paper 9a is bent in a U shape under the downward pressure of the insulating paper adsorption plate 10 and sinks into the paper bending guide groove 7 to form a U-shaped insulating paper sheet 9, and the left vertical section 9.1, the right vertical section 9.2 and the bottom section 9.3 of the U-shaped insulating paper sheet 9 are respectively attached to the left side, the right side and the bottom surface of the insulating paper adsorption plate 10, and the upper parts of the left vertical section 9.1 and the right vertical section 9.2 of the paper sheet respectively cover the several one-way air guide holes 12 on the left and right sides of the insulating paper adsorption plate 10; as shown in FIG. Figure 5 shown.

[0051] Step three, control the two-phase air pump 13 to continuously suck away the air in the empty space 31 in the board through the air guide pipe 13a, so that negative pressure is formed in the empty space 31 in the board, and the negative pressure in the empty space 31 in the board is transmitted to each one-way air guide hole 12. At this time, the upper parts of the left vertical section 9.1 and the right vertical section 9.2 of the U-shaped insulating paper sheet 9 respectively cover the plurality of one-way air guide holes 12 on the left and right sides of the insulating paper adsorption plate body 10, so that each one-way air guide hole 12 in a negative pressure state continuously and strongly adsorbs the upper parts of the left vertical section 9.1 and the right vertical section 9.2 of the U-shaped insulating paper sheet 9 under the action of negative pressure; thereby, the U-shaped insulating paper sheet 9 is adsorbed on the insulating paper adsorption plate body 10;

[0052] Step 4: The insulating paper adsorption plate 10 is driven to rise by the lifter 14, and the U-shaped insulating paper sheet 9 adsorbed on the insulating paper adsorption plate 10 rises to separate from the paper sheet bending guide groove 7. At this time, the U-shaped insulating paper sheet 9 is just between the two glue sprayers 54; Figure 6 shown.

[0053] Step 5, control the two glue sprayers 54 to spray glue mist, and make the glue mist adhere to the outer side surfaces of the left vertical section 9.1 and the right vertical section 9.2 of the U-shaped insulating paper sheet 9 that are away from each other;

[0054] Step 6: The robot arm 15 drives the insulating paper adsorption plate 10 and the U-shaped insulating paper sheet 9 tightly adsorbed by the insulating paper adsorption plate 10 to move to the top of a narrowed opening 200 on the rotor coil frame 6; Figure 3 and Figure 7 .

[0055] Step seven, the insulating paper adsorption plate 10 and the U-shaped insulating paper piece 9 tightly adsorbed by the insulating paper adsorption plate 10 are driven to descend by the lifter 14. Since the thickness of the insulating paper adsorption plate 10 is narrower than the width of the narrowed opening 200 on the rotor coil skeleton 6, the insulating paper adsorption plate 10 and the U-shaped insulating paper piece 9 tightly adsorbed by the insulating paper adsorption plate 10 are inserted downward into the winding groove 20 through the narrowed opening 200 on the rotor coil skeleton 6 during the descent process, until the bottom section 9.3 of the U-shaped insulating paper piece 9 is displaced downward to adhere to the bottom surface 10.2 of the winding groove 20; Figure 8 .

[0056] Step eight, control the two-phase air pump 13 to press the external gas into the empty space 31 in the plate through the air guide pipe 13a, so that a positive pressure is formed in the empty space 31 in the plate. Since the one-way valve in each one-way air guide hole 12 prevents the air in the empty space 31 in the plate from being discharged to the outside through each one-way air guide hole 12, the positive pressure in the empty space 31 in the plate is squeezed to the inner side of the elastic expansion skin 11 through each vent hole 140, thereby increasing the pressure on the inner side of the elastic expansion skin 11, so that the elastic expansion skin 11 is under the action of the internal pressure. The left vertical section 9.1 and the right vertical section 9.2 of the paper sheet originally attached to the left and right sides of the insulating paper adsorption plate 10 move away from each other under the action of the bulging body 11b bulging toward both sides; the glue surfaces of the left vertical section 9.1 and the right vertical section 9.2 of the rotating paper sheet moving away from each other move away from each other to the two side surfaces 10.1 of the winding groove 20 for gluing and adhering, and the installation process of a piece of flexible insulating paper is completed; Fig. 9 .

[0057] Step nine, control the two-phase air pump 13 to continuously suck away the air in the empty space 31 in the board through the air guide pipe 13a, so that the positive pressure in the empty space 31 in the board is released, and the bulging body 11b automatically shrinks to the initial state; and the left vertical section 9.1 and the right vertical section 9.2 of the U-shaped insulating paper sheet 9 are already bonded to the two groove sides 10.1 and will not recover with the shrinkage of the bulging body 11b; Fig.10 .

[0058] Step 10: Use the lifter 14 to drive the insulating paper adsorption plate 10 to rise, so that the insulating paper adsorption plate 10 is separated from the winding groove 20 where the insulating paper has been installed; then prepare for the installation of the insulating paper of the next winding groove 20, such as Fig.11 .

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
