Description

Technical Field

[0001] This invention relates to the field of automatic rotor impregnation machines, specifically a high-efficiency feeding device for an automatic rotor impregnation machine. Background Technology

[0002] A rotor refers to a rotating body supported by bearings. Objects without their own axis of rotation, such as optical discs, can be considered rotors when they are rigidly connected or have an additional shaft. Impregnation is the application of an insulating varnish to a motor rotor. The process involves manually installing the rotor onto processing equipment, which then performs the steps of rotor conveying, impregnation, and heating. The impregnation step requires a rotor impregnation machine, such as the rotor impregnation machine described in prior art with application number CN202311425526.X.

[0003] The aforementioned prior art, patent application number CN202311425526.X, describes a rotor impregnation machine with several assembly cylinders internally arranged for mounting rotors. These assembly cylinders move via a conveyor chain within the machine. However, we have found the following drawbacks in the loading of these assembly cylinders: 1. The internal structure of the rotor impregnation machine's inlet is complex, easily obstructing the operation of traditional loading devices. Furthermore, traditional loading devices have limited functionality and are not suitable for loading rotor impregnation machines. 2. Relying on frequent manual loading and unloading from left to right makes it impossible to quickly and simultaneously load and install two rotors between alternating assembly cylinders, resulting in high labor intensity and low loading efficiency. Therefore, to address these problems, we propose a high-efficiency loading device for an automatic rotor impregnation machine. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency feeding device for an automatic rotor impregnation machine in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solution: a high-efficiency feeding device for an automatic rotor impregnation machine, comprising a rotor guide mechanism, a circular electromagnet placed on one side of the rotor guide mechanism's output end, a support plate, an I-beam frame, a rotor placement box, and a rotor assembly sleeve at the part to be fed. The two rotor guide mechanisms are respectively connected to both sides of the I-beam frame, and are fixedly connected to one end of the support plate at the middle position inside the two end grooves on the same side of the I-beam frame. The rotor guide mechanism includes a lower frame, an upper frame, and magnetic columns. The lower frame has a rotor ejection groove and a rotor loading groove at its top front and rear ends, respectively. Two magnetic columns are rotatably installed in the port at the front end of the lower frame. The corresponding end structure of the rotor extends into the gap between the upper frame and the lower frame. The rotor loading groove is close to the discharge port at the bottom of the rotor placement box.

[0006] Preferably, the rotor assembly sleeve is provided in two sets, and the two sets of rotor assembly sleeves are respectively installed on two automatic impregnation conveyor chains, and the two automatic impregnation conveyor chains are connected to the same drive structure.

[0007] Preferably, the bottom of the I-beam carrier is slidably mounted on two feed guide rails, and the output end of the second cylinder is fixedly mounted at the middle position of another part of the I-beam carrier.

[0008] Preferably, the feed guide rail is in a position where the right side is lower than the left side, and the middle part of the plate structure located between one end of the two feed guide rails is fixedly connected to the cylinder body of the second cylinder.

[0009] Preferably, a strip electromagnet is installed on the side wall of the support plate.

[0010] Preferably, corresponding positions on both sides of the rotor placement box are provided with electromagnet-controlled drop areas, and the electromagnet-controlled drop areas are areas formed by assembling several electromagnets together.

[0011] Preferably, one side of the rotor placement box is connected to the servo linear motion module.

[0012] Preferably, the circular electromagnet is fixedly installed at the output end of the first cylinder, and the cylinder body of the first cylinder is fixedly connected to the other end of the support plate. The circular electromagnet, the rotor push-out groove, and the rotor mounting sleeve form a coaxial rotor push-mounting structure.

[0013] The beneficial effects of this invention are: 1. By using two rotor guide mechanisms that are parallel to each other and have the same inclination, it is beneficial to form a pair feeding structure. The corresponding ends of the rotor guide mechanisms that are pushed and pulled can move in and out between two opposing rotor assembly cylinders on the automatic paint dipping conveyor chain. This not only allows the rotor group to roll automatically and orderly to the rotor ejection groove with the help of the inclination, but also places the rotor to be fed in front of the opening of the coaxial rotor assembly cylinder, solving the problem of frequent repetition of manual rotor loading and unloading operations. Second, by simultaneously pushing and mounting each pair of rotors onto their respective rotor mounting cylinders, the feeding speed is fast and the efficiency is high. This maximizes the compatibility with the rotor mounting structure of the existing automatic rotor impregnation machine, further improving the automation level of the automatic rotor impregnation machine.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0020] Please see Figure 1-5 As shown, a high-efficiency feeding device for an automatic rotor impregnation machine includes a rotor guide mechanism 1, a circular electromagnet 210 placed on one side of the lead-out end of the rotor guide mechanism 1, a support plate 3, an I-beam frame 4, a rotor placement box 7, and a rotor assembly sleeve 10 at the part to be fed. The two rotor guide mechanisms 1 are respectively connected to both sides of the I-beam frame 4, and the middle position of the two end grooves 410 on the same side of the I-beam frame 4 is fixedly connected to one end of the support plate 3. The feed guide rail 5 is in a right-low-left-high position, and the middle part of the plate structure between one end of the two feed guide rails 5 is fixedly connected to the cylinder part of the second cylinder 6. Combination Figure 2 and Figure 3 As shown, the rotor guide mechanism 1 includes a lower frame 110, an upper frame 120, and a magnet column 130. The lower frame 110 has a rotor ejection groove 111 and a rotor loading groove 112 respectively at the front and rear ends of the top. Two magnet columns 130 are rotatably installed in the port at the front end of the lower frame 110. The corresponding end structure of the rotor extends into the gap between the upper frame 120 and the lower frame 110. The rotor loading groove 112 is close to the discharge port at the bottom of the rotor placement box 7. A strip electromagnet 310 is installed on the side wall of the support plate 3. When the bottom rotor in the rotor placement box 7 falls into the rotor loading groove 112, the feed guide rail 5 is in a right-low-left-high position, so the rotor guide mechanism 1 is also in an inclined state. As a result, the rotor located in the rotor loading groove 112 rolls freely and is arranged between the lower frame 110 and the upper frame 120, achieving the effect of a single-layer rotor arrangement. By setting two magnetic posts 130 at the corresponding ends of the lower frame 110, the rotor at the rotor ejection groove 111 can be contacted by a small magnetic force to prevent the rotor to be ejected from shaking. When the rotor located at the rotor ejection groove 111 is about to be ejected and installed on the rotor mounting sleeve 10, the bar electromagnet 310 located on the support plate 3 is energized, which plays the role of magnetically attracting and fixing the ends of other rotors. This can control the state of other rotors and prevent the corresponding part of the next rotor from rolling into the rotor landing groove 112 and affecting the reset of the circular electromagnet 210. When the circular electromagnet 210 is reset, the bar electromagnet 310 is de-energized. Under the tilting action of the rotor guide mechanism 1, the next rotor rolls down to the rotor loading groove 112, which plays the role of automatic feeding.

[0021] Combination Figure 4As shown, the circular electromagnet 210 is fixedly installed at the output end of the first cylinder 2, and the cylinder body of the first cylinder 2 is fixedly connected to the other end of the support plate 3. The circular electromagnet 210, the rotor push-out groove 111 and the rotor mounting sleeve 10 form a coaxial rotor push-mounting structure. When one end of the rotor located in the rotor loading groove 112 is moved to the front of the rotor mounting sleeve 10, the first cylinder 2 is in the extended state and moves the connected circular electromagnet 210 forward, so that the rotor that is magnetically fixed to the circular electromagnet 210 is pushed forward until the corresponding end of the rotor is inserted and fixed on the rotor mounting sleeve 10, and the rotor is completely separated from the rotor guide mechanism 1 at this time. In summary, the two rotor guide mechanisms 1, which are parallel to each other and at the same inclination, facilitate the formation of a paired feeding structure. Furthermore, the corresponding ends of the rotor guide mechanisms 1, which are pushed and pulled, can move in and out between two opposing rotor assembly cylinders 10 located on the automatic impregnation conveyor chain 9. This allows the rotor group to automatically and orderly roll to the rotor ejection groove 111 using the inclination, and also places the rotor to be fed directly in front of the opening of the coaxial rotor assembly cylinder 10. This solves the problem of frequent repetitive manual rotor loading and unloading operations. By simultaneously pushing and loading each pair of rotors onto their respective rotor assembly cylinders 10, the feeding speed is fast and efficient, maximizing compatibility with the rotor mounting structure of existing automatic rotor impregnation machines, and further enhancing the automation level of the automatic rotor impregnation machine.

[0022] like Figure 1 As shown, the rotor assembly sleeve 10 is provided in two sets, and the two sets of rotor assembly sleeve 10 are respectively installed on two automatic impregnation conveyor chains 9. The two automatic impregnation conveyor chains 9 are connected to the same drive structure. By using the running automatic impregnation conveyor chains 9, the two opposing rotor assembly sleeves 10 can be placed simultaneously in front of the corresponding rotor.

[0023] like Figure 2 As shown, the bottom of the I-beam carrier 4 is slidably mounted on two feed guide rails 5, and the output end of the second cylinder 6 is fixedly mounted at the middle position of another part of the I-beam carrier 4. When the second cylinder 6 is extended or retracted, it can push and pull the rotor guide mechanism 1. When the rotor guide mechanism 1 moves backward, it can prevent the corresponding end of the rotor guide mechanism 1 from colliding with the rod located between the two automatic impregnation conveyor chains 9.

[0024] like Figure 5As shown, corresponding parts on both sides of the rotor placement box 7 are provided with electromagnet-controlled drop areas 710, and the electromagnet-controlled drop areas 710 are areas formed by assembling several electromagnets together. When the discharge port at the bottom of the rotor placement box 7 needs to be separated from the rotor drop groove 112, the electromagnets at the electromagnet-controlled drop areas 710 are energized to generate a magnetic field to magnetically attract and fix the area and the rotor at the bottom, preventing the rotor from falling from the discharge port without restraint.

[0025] Furthermore, one side of the rotor placement box 7 is connected to the servo linear motion module 8.

[0026] Working principle: Combining Figure 2 and Figure 3 As shown, when the bottom rotor in the rotor placement box 7 falls into the rotor loading groove 112, the feed guide rail 5 is in a right-low-left-high position, so the rotor guide mechanism 1 is also in an inclined state. Thus, the rotor located in the rotor loading groove 112 rolls freely and is arranged between the lower frame 110 and the upper frame 120, achieving the effect of a single-layer rotor arrangement. By setting two magnetic posts 130 at the corresponding ends of the lower frame 110, the rotor at the rotor ejection groove 111 can be contacted by a small magnetic force to prevent the rotor to be ejected from shaking. When the rotor located at the rotor ejection groove 111 is about to be ejected and installed on the rotor mounting sleeve 10, the bar electromagnet 310 located on the support plate 3 is energized, which plays the role of magnetically attracting and fixing the ends of other rotors. This can control the state of other rotors and prevent the corresponding part of the next rotor from rolling into the rotor landing groove 112 and affecting the reset of the circular electromagnet 210. When the circular electromagnet 210 is reset, the bar electromagnet 310 is de-energized. Under the tilting action of the rotor guide mechanism 1, the next rotor rolls down to the rotor loading groove 112, which plays the role of automatic feeding. Combination Figure 4 As shown, when one end of the rotor located in the rotor loading groove 112 is moved to the front of the rotor mounting sleeve 10, the first cylinder 2 is in the extended state and moves the connected circular electromagnet 210 forward, so that the rotor that is magnetically fixed to the circular electromagnet 210 is pushed forward until the corresponding end of the rotor is inserted and fixed on the rotor mounting sleeve 10, and the rotor is completely separated from the rotor guide mechanism 1 at this time. In summary, the two rotor guide mechanisms 1, which are parallel to each other and at the same inclination, facilitate the formation of a paired feeding structure. Furthermore, the corresponding ends of the rotor guide mechanisms 1, which are pushed and pulled, can move in and out between two opposing rotor assembly cylinders 10 located on the automatic impregnation conveyor chain 9. This allows the rotor group to automatically and orderly roll to the rotor ejection groove 111 using the inclination, and also places the rotor to be fed directly in front of the opening of the coaxial rotor assembly cylinder 10. This solves the problem of frequent repetitive manual rotor loading and unloading operations. By simultaneously pushing and loading each pair of rotors onto their respective rotor assembly cylinders 10, the feeding speed is fast and efficient, maximizing compatibility with the rotor mounting structure of existing automatic rotor impregnation machines, and further enhancing the automation level of the automatic rotor impregnation machine.
