Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to an intermittent self-adhesive coating processing device for electromagnetic wires and a process thereof. Background Art

[0002] In the production of the stator, the core structure of the motor, paint coating is an indispensable link. The stator winding (electromagnetic wires wound into groups) is solidified into a whole with insulating paint, providing an unobstructed heat dissipation channel, improving the stator's earthquake resistance, insulation, moisture resistance, and corrosion resistance, thereby increasing the mechanical strength and electrical performance of the motor and delaying the aging of the motor.

[0003] There are two ways to apply paint to the stator, namely, pouring and immersion. Pouring easily causes insufficient filling of the insulating paint, while immersion easily causes the insulating paint to be applied to the outer surface of the stator, resulting in waste and requiring post-processing.

[0004] The existing publication number is CN117879287A, which discloses "a paint dipping device for a motor stator coil". Through the setting of a paint injection component, the side wall and the inner wall of the stator can be quickly sealed, so that the paint injection component and the paint dipping area on the stator form a paint dipping flow channel, and the paint dipping operation of the coil is realized through the cooperation of the conveying component. The insulating paint is injected along the paint dipping flow channel by pressure to realize the paint dipping operation;

[0005] First, there is a stator (such as Fig.11 ) The winding on the inside is multi-strand, and the winding processing is completed by automatic winding of the machine tool. The gaps between the electromagnetic wires of the multiple windings are not the same, and the difficulty of the insulating paint flowing inside is not the same. Therefore, when the multiple paint dipping channels are injected with paint at the same time, the insulating paint tends to flow into the easy-flowing paint dipping channels first, which ultimately causes the easy-flowing paint dipping channels to be injected with excessive insulating paint, which leaks out from the other side, causing waste and subsequent processing, while the difficult-flowing paint dipping channels are prone to insufficient paint dipping. In addition, it is best to have a heat dissipation channel between the windings to facilitate the heat dissipation and internal stress release of the insulating paint and the stator winding solidification as a whole. The above scheme does not achieve this effect. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0038] Combination Figure 1-Figure 11, an intermittent self-adhesive coating processing equipment for electromagnetic wires, including a machine tool and a varnishing mechanism, the machine tool has a clamp 70 that clamps a stator body 60 and moves parallel to the top of the varnishing mechanism, a telescopic cylinder that pushes the varnishing mechanism to move up and down is hinged on one side of the varnishing mechanism, the varnishing mechanism includes an outer cover 10, a sealing component 20 is provided on the upper surface of the outer cover 10, and an inflation component 30 and a varnishing component 40 are assembled inside;

[0039] Combination Figure 3-Figure 5 In order to solve the docking problem between the outer cover 10 and the stator body 60, the embodiment has the following methods: the outer cover 10 includes a mounting cover 11, the upper side of the mounting cover 11 is coaxially provided with a movable outer hoop 12 and an inner hoop 13, the upper surface of the outer hoop 12 is docked with the outer ring of the stator body 60, the upper surface of the inner hoop 13 is docked with the inner ring of the stator body 60, and an adaption component 14 is provided below the outer hoop 12 and the inner hoop 13 to promote the outer hoop 12 and the inner hoop 13 to be highly matched;

[0040] The adaptable assembly 14 includes a plurality of hydraulic lifting rods A141 arranged circumferentially on the lower surface of the outer hoop 12, and a hydraulic lifting rod B142 connected to the lower surface of the inner hoop 13. An oil pipe 143 is connected between the hydraulic cylinders of the hydraulic lifting rods A141 and the hydraulic lifting rods B142. A limiting sleeve 144 is sleeved on the outer surface of the telescopic rod of the hydraulic lifting rod A141. The limiting sleeve 144 is fixedly connected to the inner wall of the mounting cover 11.

[0041] It should be noted that the hydraulic lifting rod A141 and the hydraulic lifting rod B142 are understood to be components of the piston cylinder and the plug rod of the existing hydraulic rod, and the oil pipe 143 connects the two piston cylinders.

[0042] Furthermore, when the outer hoop 12 and the inner hoop 13 are connected to the outer ring and the inner ring of the stator body 60 respectively, the oil pipe 143 between the hydraulic lifting rod A141 and the hydraulic lifting rod B142 can make the hydraulic oil inside flow, so that the height of the outer hoop 12 and the inner hoop 13 can be adaptively adjusted relative to the outer ring and the inner ring of the stator body 60, and the two hoop 13 can be pressed against the lower surface of the stator body 60 to achieve a better sealing effect.

[0043] The arrangement of the cross-sectional area of ​​the hydraulic cylinders of the plurality of hydraulic lifting rods A141 being equal to the cross-sectional area of ​​the hydraulic cylinders of the hydraulic lifting rods B142 is conducive to the consistency of the combined force of the plurality of hydraulic lifting rods A141 on the outer hoop 12 and the supporting force of the hydraulic lifting rods B142 on the inner hoop 13.

[0044] Combination Figure 3-Figure 8In order to separate the multiple windings in the stator body 60 and seal the open groove on the inner ring of the stator body 60, this embodiment is as follows: the sealing component 20 includes an annular rubber ring 21 and a plurality of elastic rubber sleeves 22 on the upper surface of the annular rubber ring 21, the annular rubber ring 21 is provided with a paint dipping port 24 corresponding to the lower side of the winding of the stator body 60, the annular rubber ring 21 seals and covers the upper surfaces of the outer hoop 12 and the inner hoop 13, and when the outer hoop 12 and the inner hoop 13 are connected with the outer ring and the inner ring of the stator body 60, the lower side of the annular cavity formed between the outer ring and the inner ring of the stator body 60 is automatically sealed, and the elastic rubber sleeve 22 is supported by the inflatable component 30 and correspondingly inserted into the gap between the windings of the stator body 60 (such as Fig. 9 );

[0045] The inflatable component 30 includes an annular airbag 31 fixedly arranged on the lower surface of the first support plate 51, and a plurality of inflatable support tubes 32 fixedly installed on the upper surface of the second support plate 52. A plurality of vent holes 321 are opened on the side surface of the inflatable support tube 32. The inflatable support tube 32 is connected to the cavity of the annular airbag 31 through a connecting tube. An annular extrusion disk 311 is connected to the lower surface of the annular airbag 31. A first push rod 312 is hinged on the lower surface of the annular extrusion disk 311 to push it. A plurality of return springs 313 are circumferentially arranged between the annular extrusion disk 311 and the first support plate 51. The inflatable support tube 32 passes through the annular rubber ring 21. The elastic rubber sleeve 22 is sleeved on the outer surface of the inflatable support tube 32. A connecting portion 23 is connected between the elastic rubber sleeve 22 and the annular rubber ring 21. The elastic rubber sleeve 22 and the connecting portion 23 are integrally arranged. The connecting portion 23 corresponds to the opening groove of the inner ring of the stator body 60.

[0046] Furthermore, the annular extrusion plate 311 is pushed up and down by the first push rod 312 to squeeze the annular airbag 31, and the squeezed air enters the elastic rubber sleeve 22 and the annular rubber ring 21 through the vent hole 321 on the surface of the inflation support tube 32, so that the elastic rubber sleeve 22 and the connecting part 23 are expanded, and the gap between the windings of the stator body 60 is automatically filled, and the opening groove on the inner ring of the stator body 60 is also filled (such as Fig.10 ), the annular rubber ring 21 will also fit against the lower surface of the stator body 60 winding, thereby forming multiple paint dipping channels between the expanded elastic rubber sleeve 22, the connecting part 23 and the outer ring and inner ring of the stator body 60, and each stator body 60 winding is individually placed in a paint dipping channel.

[0047] Combination Figure 3-Figure 8 In order to synchronously and quantitatively inject insulating paint into multiple paint dipping channels, the present embodiment comprises: a paint injection assembly 40 comprising an annular oil tank 41 and a plurality of piston injection cylinders 42, the output end of the piston injection cylinder 42 being connected to the paint dipping port 24 on the surface of the annular rubber ring 21, and the piston injection cylinder 42 extracts the insulating paint in the annular oil tank 41 and injects it quantitatively when the paint dipping channel is formed on the periphery of the winding of the stator body 60;

[0048] A plurality of brackets are arranged circumferentially on the outer side of the annular oil tank 41 for fixed connection with the inner wall of the mounting cover 11. A hollow fixed cylinder 50 is fixedly connected to the upper surface of the annular oil tank 41. A first support plate 51 and a second support plate 52 are fixedly arranged on the outer surface of the fixed cylinder 50 from bottom to top. The upper surface of the second support plate 52 is lower than the upper surface of the elastic rubber sleeve 22 and the connecting part 23. The hydraulic lifting rod B142 movably passes through the inner side of the fixed cylinder 50 to movably support the connecting part 23.

[0049] The output end of the upper surface of the piston injection cylinder 42 is unidirectionally connected to the paint dipping port 24 on the upper surface of the annular rubber ring 21 through a first one-way valve, and the paint delivery pipe 423 on its side surface for liquid inlet is unidirectionally connected to the cavity of the piston injection cylinder 42 through a second one-way valve. The insulating paint stored in the annular oil tank 41 enters the piston injection cylinder 42 unidirectionally through the paint delivery pipe 423 and is then unidirectionally discharged from the outlet. One end of the paint delivery pipe 423 is connected to the inner side of the annular oil tank 41. The piston rods on the lower side of the multiple piston injection cylinders 42 have a common annular push plate 421, and the lower side of the annular push plate 421 is hinged with a second push rod 422 that pushes it. The piston rods of the multiple piston injection cylinders 42 are synchronously pushed by the second push rod 422 pushing the annular push plate 421;

[0050] Furthermore, because the inner volume of the piston injection cylinder 42 is constant, and the volumes of the windings of the multiple stator bodies 60 are similar, the volumes of the multiple varnish dipping channels formed after being filled with the elastic rubber sleeve 22 are similar, and the volume inside the piston injection cylinder 42 is set to a suitable size. Through cumulative experiments, it is set to an average value slightly smaller than the volume of the varnish dipping channels. In this way, the corresponding varnish dipping channels are injected with paint by the multiple piston injection cylinders 42 in a targeted manner, so that the insulating paint can be injected into the multiple varnish dipping channels synchronously and quantitatively, thereby avoiding the phenomenon of inconsistent varnish injection effects due to inconsistent internal gaps of the windings of the stator body 60;

[0051] It should be noted that: the first push rod 312 and the second push rod 422 are preferably oil cylinders, at least two of which are respectively provided and arranged circumferentially along the lower surfaces of the correspondingly connected annular extrusion plate 311 and the annular push plate 421, and the plurality of first push rods 312 and the plurality of second push rods 422 are respectively synchronously pushed through the corresponding hydraulic system;

[0052] During operation, after a paint dipping channel is formed around the stator body 60 winding, multiple piston injection cylinders 42 are pushed to inject a quantitative amount of insulating paint into the corresponding paint dipping channel. Under the action of pressure, the insulating paint flows upward into the gaps of the stator body 60 windings, and multiple stator body 60 windings are injected separately.

[0053] Combination Figure 4 , Figure 7-Figure 8In the paint dipping channel, there will be a part of the cavity between the lower surface of the stator body 60 winding and the upper surface of the annular rubber ring 21. When the inflation in the elastic rubber sleeve 22 is removed and the outer cover 10 is lowered, the insulating paint retained in the cavity is easy to leak to the upper surface of the annular rubber ring 21, affecting the sealing effect of the annular rubber ring 21 and causing cleaning difficulties. In this embodiment, an elastic rubber tube 25 is connected between the output end of the piston injection cylinder 42 and the paint dipping port 24 on the upper surface of the annular rubber ring 21. The outer surface of the elastic rubber tube 25 is sleeved with a tension spring 26. The two ends of the tension spring 26 are respectively fixed to the lower surface of the annular rubber ring 21 and the upper surface of the second support plate 52. Fixed connection, under normal circumstances, because the height of the second support plate 52 is lower than the upper surfaces of the outer hoop 12 and the inner hoop 13, the tension spring 26 pulls the portion of the surface of the annular rubber ring 21 with the elastic rubber tube 25 to make it concave into a depression. When the air in the annular rubber ring 21 and the elastic rubber sleeve 22 is removed, the depression is automatically formed, and the insulating paint remaining in the cavity will be gathered in the depression to form a temporary storage. When the next stator body 60 winding is injected with paint, the annular rubber ring 21 and the elastic rubber sleeve 22 are re-injected with air, and the insulating paint temporarily stored in the depression will be squeezed into the new stator body 60 winding again, so as to achieve reuse and avoid waste.

[0054] Combination Figure 6 , the insulating varnish injected into the stator body 60 winding is generally still in liquid state, and it needs to be moved to a drying workshop for drying later. During the movement, dripping is likely to occur. In this embodiment, an electric heating sleeve 33 is sleeved on the outer surface of the connecting tube between the inflatable support tube 32 and the annular airbag 31, and an anti-sticking material is coated on the outer surface of the elastic rubber sleeve 22. The electric heating sleeve 33 heats the air flowing into the inflatable support tube 32. After the elastic rubber sleeve 22 expands, its surface is attached to the surface of the stator body 60 winding. Therefore, during the varnish injection, The insulating paint in contact with the surface of the elastic rubber sleeve 22 will be gelled first, so that after the elastic rubber sleeve 22 retreats and detaches, the gelled insulating paint on the outer surface of the stator body 60 winding can play an isolation role and reduce the dripping phenomenon. The thickness of the elastic rubber sleeve 22 and the connecting part 23 is less than the thickness of the annular rubber ring 21. On the one hand, hot air can pass through the elastic rubber sleeve 22 and the connecting part 23 to exchange heat with the insulating paint. On the other hand, it avoids the upper surface of the annular rubber ring 21 from having an excessively high temperature, which causes the insulating paint on its surface to be gelled in a state of temporary storage.

[0055] A process for intermittent self-adhesive coating of electromagnetic wire, the operation process is as follows:

[0056] S1: Control the clamp 70 to move above the outer cover 10, and start the telescopic cylinders on both sides of the outer cover 10 to lift the outer cover 10 so that the elastic rubber sleeve 22 sleeved on the outer surface of the inflatable support tube 32 is inserted into the gap between the windings of the stator body 60;

[0057] S2: The electric heating sleeve 33 and the first push rod 312 are started at the same time. The first push rod 312 presses the annular airbag 31 upward, so that the gas is heated by the electric heating sleeve 33 and then input into the inflation support tube 32, propping up the elastic rubber sleeve 22 on the outer surface, and then filling the gap between the windings of the stator body 60, so that multiple paint dipping channels are formed, and the elastic rubber sleeve 22 is attached to the winding side surface of the stator body 60;

[0058] S3: Start the second push rod 422, and push the piston rods of the multiple piston syringes 42 at the same time, so that the piston syringes 42 inject the insulating paint quantitatively into the corresponding paint dipping channels through the paint dipping port 24, and the insulating paint is first solidified when it contacts the outer surface of the elastic rubber sleeve 22;

[0059] S4: Start the first push rod 312 again to pull down the annular extrusion plate 311, and draw the gas in the elastic rubber sleeve 22 back into the annular airbag 31, so that the elastic rubber sleeve 22 reduces in volume. At this time, the telescopic cylinders on both sides of the outer cover body 10 are controlled to lower the outer cover body 10.
