Description

Technical Field

[0001] This utility model relates to the field of stepper motor processing, specifically to a rotary glue-potting device for vacuum stepper motors. Background Technology

[0002] Currently, in order to meet the requirements of high and low temperature vacuum stepper motor windings in terms of withstand voltage strength, winding insulation, mechanical strength during operation, thermal conductivity, mechanical vibration and noise control, the common practice in the industry is to pot the stator assembly with glue.

[0003] In the existing process of potting the stator assembly of vacuum stepper motors, the small space inside the stator winding cavity makes it easy for air bubbles to remain, which often results in the potting process failing to meet the requirements of vacuum stepper motors. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rotary potting device for vacuum stepper motors. This device solves the problem that the space inside the stator winding cavity is small during the current potting process of the stator assembly of vacuum stepper motors, which easily leads to the formation of air bubbles. As a result, the potting process of the stator assembly often fails to meet the usage requirements of vacuum stepper motors.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a rotary dispensing device for a vacuum stepper motor is designed, including a chassis, a first drive motor is installed in the middle of the surface of the chassis, a turntable is installed at the drive end of the first drive motor, a plurality of connecting shafts are rotatably passed through the turntable, a driven gear is installed at the bottom of the plurality of connecting shafts, a placement plate is installed at the top of the plurality of connecting shafts, and a limit ring is installed on the placement plate;

[0006] A second drive motor is mounted on one side of the chassis surface. A drive gear is mounted on the drive end of the second drive motor. An mounting plate is mounted on the chassis on the side of the second drive motor, and a dispensing head is mounted on the mounting plate.

[0007] Preferably, an annular groove is formed on the outer surface of the chassis of the connecting shaft, and multiple baffles are installed at the bottom of the inner cavity of the annular groove. An elastic rod is fixedly connected to the bottom of the placement plate.

[0008] Preferably, the length of the elastic rod is adapted to the sum of the length from the bottom of the placement plate to the bottom of the inner cavity of the annular groove.

[0009] Preferably, telescopic rods are installed on both sides of the surface of the placement tray, a fixing ring is fixedly connected between the tops of the two telescopic rods, springs are sleeved on the outer sides of the two telescopic rods, the two ends of the two springs are respectively connected to the placement tray and the fixing ring, and a retaining ring is installed at the bottom of the fixing ring.

[0010] Preferably, the maximum extension of the spring is greater than the maximum length of the telescopic rod.

[0011] Preferably, the driving gear and the driven gear are at the same height and mesh with each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a dispensing head, a first drive motor, a second drive motor, a driven gear, a driving gear, a placement disk, a limiting ring, and a connecting shaft. The dispensing head injects glue into the stator assembly of a stepper motor, while the second drive motor rotates the driving gear, causing the glue-filled stator assembly to rotate. This displaces air bubbles in the glue longitudinally, preventing residual air bubbles from affecting the quality of the vacuum stepper motor. Furthermore, the dispensing process allows for the removal of the glued vacuum stepper motor after dispensing, followed by reinstallation of the new stepper motor. The first drive motor drives the turntable to rotate intermittently, continuously dispensing glue into the vacuum stepper motor, thus improving the efficiency of glue dispensing.

[0014] 2. This utility model combines annular grooves, baffles, and elastic rods. When the placement tray rotates, it drives the elastic rod to rotate. The baffle restricts the rotation of the elastic rod, causing it to deform. When the elastic rod deforms to a certain extent, it passes over the baffle and strikes the next baffle, generating vibration. This vibration drives the vacuum stepper motor on the placement tray to vibrate, thereby accelerating the removal of air bubbles from the stator assembly and further improving the efficiency and effect of the vacuum stepper motor potting process.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A rotary dispensing device for a vacuum stepper motor, see [link to example]. Figures 1 to 3 The system includes a chassis 1. A first drive motor 11 is mounted on the center of the surface of the chassis 1. A turntable 12 is mounted on the drive end of the first drive motor 11. Multiple connecting shafts 2 rotate through the turntable 12. A driven gear 21 is mounted on the bottom of each of the multiple connecting shafts 2, and a placement plate 22 is mounted on the top of each of the multiple connecting shafts 2. A limit ring 23 is mounted on the placement plate 22. A second drive motor 4 is mounted on one side of the surface of the chassis 1. A drive gear 41 is mounted on the drive end of the second drive motor 4. The drive gear 41 and the driven gear 21 are at the same height and mesh with each other. A mounting plate 5 is mounted on the chassis 1 on the side of the second drive motor 4. A glue-filling head 51 is mounted on the mounting plate 5. During operation, the stator assembly of the stepper motor is placed on the limit ring 2. Within 3 minutes, the first drive motor 11 is started to drive the turntable 12 to rotate so that the stator assembly of the stepper motor corresponds to the glue-filling head 51, thereby engaging the driven gear 21 with the driving gear 41. Then, glue is injected into the stator assembly of the stepper motor through the glue-filling head 51. At the same time, the second drive motor 4 is started to drive the driving gear 41 to rotate, thereby rotating the stator assembly of the stepper motor filled with glue. This removes air bubbles in the glue along the longitudinal direction, thus avoiding the impact of residual air bubbles in the stator assembly on the quality of the vacuum stepper motor. Furthermore, when filling the stator of the vacuum stepper motor with glue, the vacuum stepper motor can be disassembled after filling with glue, and then the vacuum stepper motor that needs to be filled with glue can be installed. Thus, the first drive motor 11 drives the turntable 12 to continuously fill the vacuum stepper motor with glue through intermittent rotation, thereby improving the efficiency of filling the vacuum stepper motor with glue.

[0021] For details, see Figure 1 and Figure 3An annular groove 31 is formed on the surface of the base 1 on the outer side of the connecting shaft 2. Multiple baffles 32 are installed at the bottom of the inner cavity of the annular groove 31. An elastic rod 3 is fixedly connected to the bottom of the placement plate 22. The length of the elastic rod 3 is adapted to the sum of the distance from the bottom of the placement plate 22 to the bottom of the inner cavity of the annular groove 31. When the placement plate 22 rotates, it drives the elastic rod 3 to rotate. The baffles 32 restrict the rotation of the elastic rod 3, causing it to deform. When the elastic rod 3 deforms to a certain extent, it passes over the baffles 32 and strikes the next baffle 32, generating vibration. This drives the vacuum stepper motor on the placement plate 22 to vibrate, thereby accelerating the speed of air bubble discharge in the stator assembly and further improving the efficiency and effect of the vacuum stepper motor potting.

[0022] Further, see Figure 1 and Figure 2 Telescopic rods 24 are installed on both sides of the surface of the placement tray 22. A fixing ring 26 is fixedly connected between the tops of the two telescopic rods 24. A spring 25 is sleeved on the outer side of each of the two telescopic rods 24. The two ends of the two springs 25 are respectively connected to the placement tray 22 and the fixing ring 26. A retaining ring 27 is installed at the bottom of the fixing ring 26. The maximum length of the spring 25 is greater than the maximum length of the telescopic rod 24. By pulling the fixing ring 26 upward, the spring 25 is stretched. Then, the vacuum stepper motor is placed in the limiting ring 23. Then, the fixing ring 26 is released by hand, and the tension of the spring 25 is used to pull the fixing ring 26 to the top outside of the vacuum stepper motor, thereby improving the stability of the vacuum stepper motor during glue potting.
