Description

Technical Field

[0001] The invention relates to the technical field of motor assembly, in particular to rotor assembly equipment used for producing rotors of chip-type DC variable frequency motors. Background Art

[0002] SMD DC variable frequency motor is a type of permanent magnet motor, which relies on magnetic steel to provide a magnetic field. Permanent magnet motors need magnetic steel to provide a lasting magnetic field, because the magnetic steel is permanently magnetized and can provide a stable magnetic field for the motor.

[0003] A motor rotor magnet assembly device on the market can automatically inject glue into the magnet installation groove of the rotor. After the glue injection is completed, the magnet can be inserted into the rotor magnet installation groove from top to bottom. Since the magnet will push the glue in the installation groove out from its bottom during the insertion of the magnet into the rotor installation groove, the device is also equipped with a scraper to scrape off the glue pushed out by the magnet at the bottom of the rotor. However, after the scraper scrapes off the squeezed glue, the scraped glue will adhere to the outside of the scraper. If the glue attached to the scraper cannot be cleaned in time, the glue will solidify on the outside of the scraper, causing the scraping end of the scraper to become thicker, thereby affecting the subsequent scraping effect of the scraper. Since the scraper is installed on the inside of the frame, the space inside the frame is relatively narrow. When personnel clean the glue attached to the outside of the scraper on the inside of the frame, they will not only encounter many obstacles, but also have a visual blind spot, resulting in time-consuming and labor-intensive cleaning of the glue attached to the outside of the scraper, which seriously affects the assembly efficiency of the rotor and magnet.

[0033] The cleaning assembly includes a guide tube 14 fixedly embedded in the base 1, and the scraper 5 is in plug-in contact with the guide tube 14. Two symmetrically distributed cleaning brushes 15 are installed on the inner side of the guide tube 14, and the cleaning brushes 15 are close to the upper end of the guide tube 14.

[0036] One end of the hard conduit 18 away from the hollow box 16 is fixedly connected to a conduit 1 21, and one end of the conduit 1 21 away from the hard conduit 18 is fixedly connected to a sleeve 22. A conduit 23 is fixedly installed on the lower end of the sleeve 22. Both conduit 1 21 and conduit 23 are equipped with a one-way valve 24. A piston 25 that can move up and down is movably embedded in the interior of the sleeve 22. A long connecting rod 26 is fixedly embedded at the center of the upper end of the piston 25. A gasket 27 is fixedly connected to the upper end of the long connecting rod 26. A spring 28 is movably sleeved on the outer side of the long connecting rod 26, and the two ends of the spring 28 are movably abutted against the sleeve 22 and the gasket 27 respectively. The spring 28 can drive the piston 25 to move up and reset.

[0037] Working principle: The personnel first install the rotor on the support platform 2, and then the hydraulic column 3 drives the support platform 2 to move up to a certain height. Then the glue injection equipment in the rotor magnetic steel production line injects a certain amount of glue into the rotor magnetic steel installation groove. After the glue injection is completed, the magnetic steel embedding equipment in the production line embeds the magnetic steel into the rotor installation groove. After the magnetic steel enters the rotor installation groove, part of the glue in the installation groove will be squeezed out by the magnetic steel. After the rotor magnetic steel is assembled, the drive motor 12 drives the gear 9 to rotate, and the gear 9 drives the ring 4 and the scraper 5 to rotate through the inner gear ring 8. The scraper 5 scrapes off the overflow glue at the bottom of the rotor during the rotation process. The scraper 5 stops at its initial position after rotating several circles;

[0038] Afterwards, the hydraulic column 3 drives the support platform 2 to move downward. When the scraper 5 moves to the vicinity of the guide tube 14, the gasket 27 is against the top of the cylindrical groove 33. The personnel remove the assembled rotor, and the hydraulic column 3 drives the support platform 2 and the scraper 5 to move downward again. At the same time, the pressure rod 31 drives the piston 25 to move downward inside the sleeve 22 through the long connecting rod 26, and squeezes the degumming solvent inside the sleeve 22 into the cleaning brush 15. The scraper 5 will contact and rub with the two cleaning brushes 15 during the downward movement, which is conducive to dissolving and brushing the degumming solvent attached to the surface of the scraper 5, preventing the glue from solidifying on the outside of the scraper 5 and affecting the scraping effect of the scraper 5 in the later stage. The degumming solvent squeezed out from the cleaning brush 15 will enter the liquid storage tank 34 through the guide tube 14, and the degumming solvent filtered by the filter cotton 36 can be reused, which is conducive to saving resources.

[0039] When the support platform 2 lifts the rotor upward to install the magnetic steel, the pressure rod 31 is separated from the gasket 27. At this time, the piston 25 is driven by the compression force of the spring 28 to move upward and reset. During this process, the degumming agent in the liquid storage tank 34 will be sucked into the sleeve 22.

[0040] Example 2: Please refer to Figure 5-Figure 7 This embodiment further explains Example 1. A driving assembly is installed between the cleaning assembly and the support platform 2. The driving assembly includes a short connecting rod 29 fixedly installed at the center of the lower end of the hollow box 16. The lower ends of the two short connecting rods 29 are fixedly connected with a bending connecting rod 30, and the connection method between the bending connecting rod 30 and the guide tube 14 is a plug-in connection. The cross-sectional shape of the bending connecting rod 30 is circular.

[0041] A pressure rod 31 is movably abutted against the outer side of the bending connecting rod 30, and the connection between the pressure rod 31 and the support platform 2 is a fixed connection. The cross-sectional shape of the pressure rod 31 is circular, and a plurality of grooves 32 distributed at equal distances are provided on the side of the pressure rod 31 close to the bending connecting rod 30, and the pressure rod 31 is in sliding contact with the pressure rod 31 through the plurality of grooves 32. A cylindrical groove 33 is provided at the lower end of the pressure rod 31, and the gasket 27 is movably abutted against the pressure rod 31 through the cylindrical groove 33.

[0042] In this embodiment, when the pressure rod 31 moves downward inside the machine base 1, the bent connecting rod 30 slides and contacts with the pressure rod 31 through the plurality of grooves 32, and cooperates with the driving force of the compression elastic force of the spring 20 to facilitate the cleaning brush 15 to move back and forth inside the guide tube 14. When the scraper 5 moves downward, the cleaning brush 15 moves back and forth and contacts and rubs with the scraper 5, which can further improve the cleaning effect of the cleaning brush 15 on the scraper 5. When the scraper 5 moves as a whole to the upper side of the cleaning brush 15 (such as Figure 5 As shown), at this time, the pressure rod 31 will still contact the bent connecting rod 30 through the groove 32 during the upward movement, that is, during the process of the support platform 2 lifting the rotor, the cleaning brush 15 will reciprocate left and right in the guide tube 14 for a period of time, and the hollow box 16 will repeatedly hit the inner wall of the guide tube 14 driven by the compression force of the spring 20, so that the cleaning brush 15 vibrates, which is conducive to the cleaning brush 15 vibrating and shaking off the dissolved glue.

[0043] Example 3: Please refer to Figure 8 This embodiment further illustrates the second embodiment. Preferably, the convex ribs 13 are fixedly mounted on the scraper 5, and the number of the convex ribs 13 on the scraper 5 is two groups, and they are symmetrically distributed, and the shape of the convex ribs 13 is U-shaped.

[0044] In this embodiment: after the scraper 5 scrapes off the overflowed glue at the bottom of the rotor, the glue is located between the two ribs 13. During the rotation of the scraper 5, the ribs 13 limit the flow path of the glue, which can prevent the scraper from throwing off the glue during the rotation and prevent the glue from falling on other equipment and solidifying.
