Description

Technical Field

[0001] The invention relates to the technical field of motor manufacturing, and in particular to a stator glue pouring device. Background Art

[0002] The stator is one of the core components of rotating equipment such as electric motors. Its main function is to work with the rotor to generate electromagnetic induction. However, during operation, the stator needs to maintain high insulation and heat resistance. In order to achieve this goal, glue filling is usually used to provide electrical insulation protection for the stator.

[0003] When existing glue pouring equipment is pouring glue inside the stator, it generally uses vacuum extraction to remove bubbles inside the insulating glue. When this method is used to defoam the inside of the stator, some larger bubbles or bubbles that are deeply deposited may require longer vacuum treatment to be discharged. However, if the vacuum pressure is insufficient or the surface tension of the glue is large, the bubbles may still be trapped in the glue layer, resulting in the inability to completely remove the bubbles deposited at the bottom of the insulating glue by vacuum extraction, which will affect the later molding quality of the insulating glue inside the stator.

[0004] To this end, the present invention provides a stator glue pouring device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The present invention provides a stator glue pouring device, comprising a stator body and a glue pouring pipe; a plastic stick is inserted into the interior of the stator body, a sealing cover is installed on the surface of the stator body through a threaded structure, an exhaust pipe is installed on one side of the top of the sealing cover, a glue pouring pipe is installed at the central position of the top of the sealing cover, and a defoaming mechanism is installed on one side of the top of the sealing cover close to the glue pouring pipe; In order to further realize the defoaming treatment inside the insulating glue, the defoaming mechanism includes a double-headed motor, a turntable, a connecting rod, a connecting seat and a knocking rod. A double-headed motor is installed on the side of the top of the sealing cover close to the glue filling tube, a turntable is installed on the output end of the top of the double-headed motor, a connecting rod is rotatably installed at the eccentric top of the turntable, a connecting seat is installed on the side of the sealing cover, a knocking rod is rotatably installed inside the connecting seat, and the top of the knocking rod is rotatably connected to the inner top of one end of the connecting rod.

[0007] Preferably, in order to protect the knocking end of the knocking rod and the outside of the sealing cover, a protective cover is installed on the outside of the knocking end of the knocking rod.

[0008] Preferably, in order to realize uniform conveying of the insulating glue, a connecting tube is installed near the inner top of the glue filling tube of the sealing cover, and a diverter plate is installed at the bottom of the connecting tube.

[0009] Preferably, a plurality of groups of glue injection holes are provided at the bottom of the diverter plate, and the glue injection holes are evenly distributed at the bottom of the diverter plate.

[0010] Preferably, in order to process the partially solidified insulating glue inside the diverter plate, a heating component is installed on the top of the diverter plate, and the heating component is in a ring shape.

[0011] Preferably, in order to improve the conveying and distribution effect of the diverter disk on the insulating glue, a transmission disk 1 is installed on the outer side of the diverter disk, and a transmission disk 2 is installed on the outer side of the bottom output end of the double-headed motor, and the transmission disk 1 and the transmission disk 2 are gear-engaged for transmission.

[0012] Preferably, in order to monitor the amount of insulating glue delivered, a quantitative valve is installed on the outer side of the glue filling pipe.

[0013] Preferably, in order to detect the vacuum degree when glue is poured inside the stator body, a pressure monitoring device is installed on one side of the top of the sealing cover, and the detection end of the pressure monitoring device is located inside the sealing cover.

[0014] 1. The beneficial effects of the present invention are as follows: the stator glue filling equipment described in the present invention is used in combination with an exhaust pipe, a double-headed motor, a turntable, a connecting rod, a connecting seat and a knocking rod. The exhaust pipe is connected to an external vacuum equipment to perform a preliminary defoaming treatment on the insulating glue between the sealing cover and the stator body. The double-headed motor works and one of the output ends drives the turntable to rotate, so that the connection point between the connecting rod and the turntable is close to one end of the connecting seat. The knocking rod rotates at the connection with the connecting seat, and the knocking end of the knocking rod knocks on the outside of the sealing cover, so that the insulating glue inside the stator body can be further defoamed. The exhaust pipe and the knocking rod are used in combination, so that the bubbles deposited at the bottom of the stator body can be defoamed better and faster, thereby improving the later molding quality of the insulating glue inside the stator body.

[0015] 2. The stator glue pouring equipment described in the present invention is used in conjunction with a connecting tube, a shunt plate, and glue pouring holes. Through multiple groups of glue pouring holes at the bottom of the shunt plate, the insulating glue can be evenly and equidistantly delivered to the inside of the stator body, avoiding uneven distribution of the insulating glue delivery and affecting the later curing and molding effect of the insulating glue inside the stator body.

[0016] 3. The stator glue filling equipment described in the present invention is used in combination with a transmission disc 2 and a transmission disc 1. When the double-headed motor is working, the output end of the other end will drive the transmission disc 2 to rotate. The transmission disc 2 and the transmission disc 1 are meshed with gears for transmission, which can drive the diverter disc 1 to rotate via the connecting tube, thereby changing the position of the insulating glue delivered to the inside of the stator body from the glue filling hole at the bottom of the diverter disc, and further improving the delivery and distribution effect of the diverter disc on the insulating glue.

[0020] Embodiment 1 The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 5 , this application provides a stator glue filling device, please refer to Figure 1 and Figure 2 , including a stator body 1 and a glue pouring pipe 3; a plastic rod 101 is inserted into the interior of the stator body 1, a sealing cover 2 is installed on the surface of the stator body 1 through a threaded structure, an exhaust pipe 201 is installed on one side of the top of the sealing cover 2, a glue pouring pipe 3 is installed at the central position of the top of the sealing cover 2, and a defoaming mechanism 4 is installed on one side of the top of the sealing cover 2 close to the glue pouring pipe 3; The defoaming mechanism 4 includes a double-headed motor 401, a turntable 402, a connecting rod 403, a connecting seat 404 and a knocking rod 405. The double-headed motor 401 is installed on the side of the top of the sealing cover 2 close to the glue filling tube 3, the turntable 402 is installed on the output end of the top of the double-headed motor 401, the connecting rod 403 is rotatably installed at the eccentric top of the turntable 402, the connecting seat 404 is installed on the side of the sealing cover 2, and the knocking rod 405 is rotatably installed inside the connecting seat 404, and the top of the knocking rod 405 is rotatably and rotatably connected to the inner top of one end of the connecting rod 403.

[0021] Please refer to Figure 4 A protective cover 7 is installed on the outer side of the knocking end of the knocking rod 405.

[0022] Specifically, the exhaust pipe 201 is connected to an external vacuum pumping device, and the exhaust end of the exhaust pipe 201 is located inside the sealing cover 2. The plastic rod 101 is inserted into the inside of the stator body 1, the sealing cover 2 is sleeved on the stator body 1 and tightened, and then the external insulating glue is poured into the inside of the stator body 1 outside the plastic rod 101 through the glue pouring tube 3, and then the sealing cover 2 and the stator body 1 are vacuumed through the exhaust pipe 201 by the external vacuum pumping device to remove the bubbles in the insulating glue, and the defoaming mechanism 4 is used to further defoam the inside of the insulating glue, and the double-headed motor 401 works. One of the output ends of the double-headed motor 401 drives the turntable 402 to rotate, and the connecting rod 403 and the rotating disk 402 are connected. The connection point of the disk 402 will change. When the connection point of the connecting rod 403 and the turntable 402 is close to one end of the connecting seat 404, the knocking rod 405 will rotate at the connection with the connecting seat 404, and then the knocking end of the knocking rod 405 will knock on the outside of the sealing cover 2, and the insulating glue inside the stator body 1 will be further defoamed to prevent some bubbles from settling at the bottom and causing bubble residue. The protective cover 7 is made of rubber. The protective cover 7 can prevent the knocking rod 405 from directly contacting the outside of the sealing cover 2, thereby protecting the knocking end of the knocking rod 405 and the outside of the sealing cover 2. After that, the insulating glue in the stator body 1 is thermally cured to form a hollow stator.

[0023] Please refer to Figure 3 A connecting tube 5 is installed at the inner top of the sealing cover 2 near the glue filling tube 3, and a diverter plate 501 is installed at the bottom of the connecting tube 5.

[0024] Please refer to Figure 3 A plurality of groups of glue injection holes 502 are provided at the bottom of the diverter plate 501 , and the glue injection holes 502 are evenly distributed at the bottom of the diverter plate 501 .

[0025] Specifically, in order to achieve uniform transportation of the insulating glue and avoid excessive insulating glue remaining on the plastic rod 101 and causing waste, the connecting tube 5 is relatively rotatably arranged on the inner top of the sealing cover 2, and the interior of the connecting tube 5 and the diverter disk 501 is in a cavity state, which is connected to the interior of the glue filling tube 3. When the insulating glue is transported to the interior of the diverter disk 501 through the glue filling tube 3 via the connecting tube 5, the insulating glue can be evenly transported to the interior of the stator body 1 at equal distances through the multiple groups of glue filling holes 502 at the bottom of the diverter disk 501, thereby avoiding uneven distribution of the insulating glue transportation, which affects the curing and molding effect of the insulating glue inside the stator body 1 in the later stage.

[0026] Please refer to Figure 3 and Figure 5 A heating component 8 is installed on the top of the diverter plate 501, and the heating component 8 is in a circular ring shape.

[0027] Specifically, in order to process the partially solidified insulating glue inside the diverter disk 501, the diverter disk 501 is assembled by bolts, and the heating component 8 is composed of heating wires. As the heat emitted by the heating component 8 increases, the partially solidified insulating glue inside the diverter disk 501 can be softened at high temperature, making it easier for workers to disassemble and maintain the diverter disk 501 later.

[0028] Please refer to Figure 3 A transmission disc 1 503 is installed on the outer side of the diverter disc 501, and a transmission disc 2 6 is installed on the outer side of the bottom output end of the double-headed motor 401. The transmission disc 1 503 and the transmission disc 2 6 are gear-engaged for transmission.

[0029] Specifically, in order to improve the conveying and distribution effect of the diverter disk 501 on the insulating glue, when the double-headed motor 401 is working, the output end of the other end of the double-headed motor 401 will drive the transmission disk 2 6 to rotate, and the transmission disk 2 6 and the transmission disk 1 503 are gear-engaged for transmission, which can prompt the transmission disk 1 503 to drive the diverter disk 501 to rotate through the connecting tube 5, thereby changing the position of the insulating glue conveyed to the inside of the stator body 1 by the glue filling hole 502 at the bottom of the diverter disk 501, thereby further improving the conveying and distribution effect of the insulating glue by the diverter disk 501.

[0030] Please refer to Figure 1 A quantitative valve 301 is installed on the outside of the glue filling tube 3.

[0031] Specifically, in order to monitor the amount of insulating glue delivered, the metering valve 301 is an electric metering valve of Festo, which can provide high-precision flow control to avoid excessive or insufficient delivery of insulating glue, resulting in waste of resources or unqualified molding quality.

[0032] Please refer to Figure 1A pressure monitoring device 202 is installed on one side of the top of the sealing cover 2 , and a detection end of the pressure monitoring device 202 is located inside the sealing cover 2 .

[0033] Specifically, in order to detect the vacuum degree when glue is poured inside the stator body 1, the pressure monitoring device 202 is an XYK-PK-V01 vacuum pressure sensor, which is used for pressure monitoring in a vacuum environment and has high accuracy and stability. The pressure monitoring device 202 can monitor the pressure changes inside the stator body 1 in real time, thereby ensuring the vacuum effect and avoiding residual bubbles when glue is poured inside the stator body 1, which affects the molding quality of the insulating glue inside the stator body 1.

[0034] Working principle: After the stator wire core and insulator are installed, the plastic rod 101 is inserted into the inside of the stator body 1, the sealing cover 2 is put on the stator body 1 and tightened, and then the external insulating glue is poured into the inside of the stator body 1 outside the plastic rod 101 through the glue filling tube 3, and then the sealing cover 2 and the stator body 1 are vacuumed through the vacuum pipe 201 by the external vacuum equipment to remove the bubbles in the insulating glue. At the same time, the double-headed motor 401 works, and one of the output terminals of the double-headed motor 401 is The turntable 402 is driven to rotate, and the connection point between the connecting rod 403 and the turntable 402 will change. When the connection point between the connecting rod 403 and the turntable 402 is close to one end of the connecting seat 404, the knocking rod 405 will rotate at the connection with the connecting seat 404, and then the knocking end of the knocking rod 405 will knock on the outside of the sealing cover 2, and the insulating glue inside the stator body 1 will be further defoamed. Finally, after the insulating glue in the stator body 1 is thermally cured, the plastic rod 101 is pulled out to form a hollow stator.

[0035] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
