Description

Technical fields:

[0001] This utility model belongs to the technical field of rotor processing, and specifically refers to a synchronous glue coating device for motor rotors. Background technology:

[0002] The rotor of an electric motor enables the rotating components of an engine or generator to convert electrical energy into mechanical energy through interaction with the electromagnetic field of the stator.

[0003] A type of rotor, such as Figure 1 As shown, the rotor body includes a rotor body 8, an S-pole magnetic tile 81, and an N-pole magnetic tile 82. Several glue grooves 83 are provided on the outer peripheral wall of the rotor body 8. The glue grooves 83 are arranged circumferentially around the axis of the rotor body 8. The glue grooves 83 are respectively used for the S-pole magnetic tile 81 and the N-pole magnetic tile 82 to be inserted. The S-pole magnetic tile 81 and the N-pole magnetic tile 82 are arranged in a cross pattern. The S-pole magnetic tile 81 and the N-pole magnetic tile 82 are fixed to the rotor body 8 with glue. The rotor body 8 is provided with a positioning groove 84 to facilitate the positioning of the rotor body 8 during assembly.

[0004] In actual production, it is necessary to manually apply glue to the glue tank and then assemble the S-pole magnetic tile and N-pole magnetic tile onto the rotor body in sequence. Manually, only one glue tank can be applied at a time, which is inefficient and needs to be improved. Summary of the Invention:

[0005] The purpose of this invention is to provide a synchronous adhesive coating device for motor rotors to solve the technical problems mentioned in the background section.

[0006] This utility model is implemented as follows:

[0007] A synchronous glue-applying device for an electric motor rotor includes a glue-applying platform, a mounting base that is lifted and slidably connected to the glue-applying platform, and a plurality of glue-applying mechanisms disposed on the glue-applying platform. The plurality of glue-applying mechanisms are distributed circumferentially around the mounting base. The mounting base is used to position the rotor body. The glue-applying platform is provided with a driving component, which drives the mounting base to lift and lower. The glue-applying mechanisms correspond one-to-one with the glue tanks of the rotor body in terms of position and number, and can apply glue to the corresponding glue tanks.

[0008] By adopting the above technical solution, in the actual glue application process, the rotor body is placed on the mounting base so that the position of the glue tank on the rotor body corresponds to the position of the glue application mechanism. The drive unit drives the rotor body to move into the space between several glue application mechanisms, and the several glue application mechanisms simultaneously apply glue towards the corresponding glue tank, which greatly improves the glue application efficiency.

[0009] Preferably, the glue application mechanism includes a glue application unit and a glue inlet pipe. A pressure glue storage tank is provided on the glue application platform. The glue application unit is located on the glue application platform. The input end and output end of the glue inlet pipe are respectively connected to the pressure glue storage tank and the glue application unit.

[0010] By adopting the above technical solution, during the glue application process, the pressure storage tank pressurizes the glue, which is then squeezed into the glue application unit through the glue inlet pipe. The glue is then sprayed into the glue tank through the glue application unit. The glue is delivered by pressure blowing, which makes the glue output uniform and thus makes the glue application uniform, which helps to improve the glue application quality.

[0011] Preferably, the glue application unit is slidably connected to the glue application table, and the glue application table is provided with a driving mechanism, which drives the glue application unit to move closer to or away from the mounting base.

[0012] By adopting the above technical solution, the glue application unit is moved closer to the mounting base to apply glue into the glue tank of the rotor body when glue application is required, and moved away from the mounting base when glue application is not required. This facilitates the entry of rotor bodies of different diameters into several glue application units, which helps to improve applicability.

[0013] Preferably, the glue application platform is provided with a cover plate, and the glue application platform and the cover plate are spliced ​​together to form an installation groove, and a plurality of the glue application mechanisms are located in the installation groove.

[0014] By adopting the above technical solution and setting the glue application mechanism inside the installation groove, it is beneficial to reduce the entry of dust, impurities and other contaminants into the glue application mechanism.

[0015] Preferably, a gap is left between the cover plate and the mounting base, and the gap is arranged around the outer periphery of the mounting base.

[0016] By adopting the above technical solution, it is beneficial to maintain a distance between the cover plate and the rotor body when the mounting base moves the rotor body into the space between several gluing mechanisms, which helps to reduce the friction between the cover plate and the rotor body.

[0017] Preferably, the cover plate is provided with positioning bolts, which pass through the cover plate and are threadedly connected to the glue application table, and the cover plate is fixed to the glue application table by the positioning bolts.

[0018] By adopting the above technical solution, the cover plate and the glue application table are fixed by positioning bolts. When the glue application mechanism needs to be repaired or maintained, it is easy to remove the cover plate from the glue application table to expose the glue application mechanism.

[0019] Preferably, the driving component is an adjustable stroke cylinder.

[0020] By adopting the above technical solution, when the height of the rotor body to be coated with glue is different, the glue coating mechanism can be aligned with the glue tank of the rotor body at different heights by adjusting the cylinder stroke.

[0021] Preferably, the mounting base is provided with a limiting post, which engages with the positioning groove of the rotor body to position the rotor body.

[0022] By adopting the above technical solution, in actual operation, the glue tank can be aligned with the glue application mechanism by inserting the limiting post into the positioning groove, without the need to adjust the rotor body.

[0023] The outstanding advantages of this utility model compared to the prior art are:

[0024] 1. In the actual glue application process, the rotor body is placed on the mounting base so that the position of the glue tank on the rotor body corresponds to the position of the glue application mechanism. The driving component drives the rotor body to move into the space between several glue application mechanisms. Several glue application mechanisms simultaneously apply glue towards the corresponding glue tank, which greatly improves the glue application efficiency.

[0025] 2. The pressure storage tank of this utility model pressurizes the glue so that it is squeezed into the glue coating unit through the glue inlet pipe, and then sprayed into the glue tank through the glue coating unit. The glue is delivered by pressure blowing, so that the glue is evenly dispensed and evenly coated, which helps to improve the glue coating quality.

[0026] 3. This utility model uses a drive mechanism to move the glue application unit closer to the mounting base to apply glue into the glue tank of the rotor body when glue application is needed, and to move it away from the mounting base when glue application is not needed. This facilitates the application of several glue application units between rotor bodies of different diameters, which is beneficial to improving applicability. Attached image description:

[0031] The present invention will be further described below with reference to specific embodiments:

[0032] This application discloses an electronic rotor synchronous adhesive coating device. See also... Figure 2 and Figure 3 An electronic rotor synchronous gluing device includes a gluing platform 1, a mounting base 2, and several gluing mechanisms 3. The gluing platform 1 is provided with a processing station 11. The table surface of the gluing platform 1 is recessed at the processing station 11. A cover plate 4 is fixed on the gluing platform 1. The cover plate 4 covers the recessed part of the gluing platform 1. The cover plate 4 and the gluing platform 1 are spliced ​​to form a mounting groove 12. Several gluing mechanisms 3 are located in the mounting groove 12.

[0033] See Figure 2 and Figure 3 The mounting base 2 is used to position the rotor body 8. The mounting base 2 slides and rises on the gluing platform 1. Several gluing mechanisms 3 are evenly distributed around the outer periphery of the mounting base 2. The position and number of the gluing mechanisms 3 correspond one-to-one with the position and number of the glue tanks 83 in the rotor body 8. A driving component 5 is fixed on the gluing platform 1. The driving component 5 is an adjustable stroke cylinder 51. The adjustable stroke cylinder 51 is located below the platform surface of the gluing platform 1 and below the mounting base 2. The piston rod of the adjustable stroke cylinder 51 is fixed to the mounting base 2. The adjustable stroke cylinder 51 drives the mounting base 2 to rise and fall, thereby driving the rotor body 8 to rise and fall.

[0034] When applying adhesive, the rotor body 8 is located in the middle of several adhesive application mechanisms 3. When the adhesive application is completed, the mounting base 2 extends out of the top of the cover plate 4.

[0035] See Figure 2 and Figure 3 The mounting base 2 has several limiting posts 21 fixed on its upper end. The position and number of the limiting posts 21 correspond one-to-one with the position and number of the positioning grooves on the rotor body 8. The limiting posts 21 are engaged with the positioning grooves of the rotor body 8 to position the rotor body 8. After the rotor body 8 is positioned on the mounting base 2, the position of the glue application mechanism 3 is aligned with the position of the glue tank 83 of the rotor body 8. The glue application mechanism 3 is used to apply glue to the corresponding glue tank 83.

[0036] See Figure 2 and Figure 3 The glue application mechanism 3 includes a glue application unit 31 and glue inlet pipes 32. The glue application unit 31 is located in the mounting groove 12 and is slidably connected to the glue application platform 1. The sliding direction of the glue application unit 31 is perpendicular to the sliding direction of the mounting base 2. Several glue application units 31 slide closer to or further away from the mounting base 2. A pressure storage tank 6 is placed on the glue application platform 1. The pressure storage tank 6 is located below the surface of the glue application platform 1. The input ends of several glue inlet pipes 32 are connected to the pressure storage tank 6, and the output ends of several glue inlet pipes 32 are fixed to the corresponding glue application unit 31. An outlet 13 is opened on the glue application platform 1. The outlet 13 is connected to the mounting groove 12, and the glue outlet pipe passes through the outlet 13 and exits the mounting groove 12.

[0037] In this embodiment, a booster pump is installed on the pressure storage tank 6, and a flow divider is connected to the booster pump. The pressure storage tank 6 is connected to several dispensing pipes through the flow divider.

[0038] See Figure 2 and Figure 3 A drive mechanism 7 is fixed on the glue application table 1. The drive mechanism 7 is located in the mounting groove 12. The drive mechanism 7 includes several telescopic cylinders 71. The position and number of telescopic cylinders 71 correspond one-to-one with the position and number of glue application units 31. The glue application units 31 are slidably connected to the glue application table 1. The sliding direction of the glue application units 31 is perpendicular to the sliding direction of the mounting base 2. The glue application units 31 slide closer to or away from the mounting base 2. The extension and retraction direction of the piston rod of the telescopic cylinder 71 is parallel to the sliding direction of the corresponding glue application unit 31. The piston rod of the telescopic cylinder 71 is fixedly connected to the corresponding glue application unit 31. Several telescopic cylinders 71 are connected in series. When the rotor body 8 is located between several glue application units 31, the telescopic cylinder 71 drives the corresponding glue application unit 31 to move closer to the corresponding glue tank 83 for glue application. After the glue application is completed, the telescopic cylinder 71 drives the corresponding glue application units 31 to move away from each other.

[0039] In other embodiments, the driving device may also include a plurality of piezoelectric ceramic brakes arranged around the circumference to drive the corresponding adhesive application unit 31 to move; the driving device may also be a pneumatic muscle, which drives the adhesive application unit 31 to move by expanding and contracting the pneumatic muscle.

[0040] See Figure 2 and Figure 3 The glue application platform 1 is also equipped with a start button 14 and a controller. The controller is electrically connected to the pressure storage tank 6, the telescopic cylinder 71, and the adjustable stroke cylinder 51. Pressing the start button 14 controls the controller to start. During the glue application process, the mounting base 2 protrudes from the upper end of the cover plate 4, and the rotor body 8 is installed on the mounting base 2. After installation, pressing the start button 14 causes the controller to control the adjustable stroke cylinder 51 to drive the mounting base 2 to descend, causing the rotor body 8 to enter between several glue application units 31. After the rotor body 8 is in place, the controller then controls the telescopic cylinders 71 to move the glue application units 31 closer to the corresponding glue tank 83. The pressure storage tank 6 pressurizes, so that the glue is evenly sprayed on the inner wall of the water tank. After spraying is completed, the adjustable stroke cylinder 51 drives the mounting base 2 to rise, causing the rotor body 8 to leave the mounting slot 12 and return to its original position above the cover plate 4, making it easy for workers to remove. The controller is not shown in the attached drawings of the instruction manual; in this embodiment, the controller is a PLC controller.

[0041] In other embodiments, the drive unit can be a linear motor, hydraulic cylinder, stepper motor, or lead screw, etc.

[0042] See Figure 2 and Figure 3The cover plate 4 has a clearance opening 41 for the mounting base 2 to pass through. When the mounting base 2 is located in the clearance opening 41, a gap 42 is left between the mounting base 2 and the inner wall of the clearance opening 41. The gap 42 is set around the outer periphery of the mounting base 2 to facilitate the passage of rotor bodies 8 of different diameters through the cover plate 4.

[0043] See Figure 2 and Figure 3 The cover plate 4 is provided with several positioning bolts 43, which are evenly distributed around the outer periphery of the recess of the glue dispensing platform 1. The positioning bolts 43 passing through the cover plate 4 are threadedly fixed to the glue dispensing platform 1. When the glue dispensing unit needs maintenance, the positioning bolts 43 are rotated to disengage the glue dispensing platform 1 and the cover plate 4, and the cover plate 4 is removed from the glue dispensing platform 1 to expose the mounting groove 12 for easy maintenance.

[0044] The implementation principle of the synchronous glue coating device for motor rotor in this application embodiment is as follows: the glue coating mechanism 3 applies glue to multiple glue tanks 83 simultaneously, which is beneficial to improving the glue coating efficiency, and the glue coating mechanism 3 dispenses glue evenly, which is beneficial to improving the glue coating quality.

[0045] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made to the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
