Description

Technical Field

[0001] The invention relates to the technical field of motor rotor manufacturing, and in particular to a rotor assembly and glue dispensing integrated device for a high-speed brushless motor. Background Art

[0002] In the manufacturing process of motor rotors, glue dispensing is a crucial link. The rotor is usually assembled from parts such as a shaft and a magnetic steel, and these parts need to be bonded together with glue to ensure the stability and reliability of the rotor when it rotates at high speed. Glue not only plays a fixing role, but also prevents the magnetic steel from loosening or falling off when the rotor runs at high speed, thereby avoiding vibration, noise, and even damage to the internal structure of the motor during operation. In addition, the uniform application of glue can also improve the dynamic balance performance of the rotor, reduce energy loss and heat generation during motor operation, and extend the service life of the motor.

[0003] Traditional dispensing devices usually adopt manual or semi-automatic assembly methods. The accuracy of fixtures and guide rails is low, and there is a lack of precise positioning mechanism, which easily leads to errors in the clamping and moving process of the workpiece, and cannot meet the requirements of high-precision assembly. For example, the maximum tolerance between the shaft and the magnetic steel hole is only 0.001-0.01mm. It is difficult for traditional devices to ensure such high assembly accuracy, resulting in unstable assembly quality and affecting product performance. In addition, due to the lack of integrated design such as automated conveying, clamping, alignment and dispensing, the assembly and dispensing processes cannot be carried out continuously, and it is difficult for traditional devices to achieve one-time automatic completion of assembly and dispensing. In traditional motor rotor dispensing devices, since the rotor is stationary during the dispensing process, the dispensing head can only dispense glue along a fixed path, and the glue cannot be evenly applied to the contact area between the shaft and the magnetic steel, resulting in excessive accumulation of glue in some areas and insufficient application in other areas, forming an uneven glue layer, affecting the dynamic balance performance and bonding strength of the rotor, and ultimately affecting the overall performance and service life of the motor. In addition, it also limits the dispensing accuracy of traditional dispensing machines on complex structure workpieces, and cannot meet the production requirements of high-precision motor rotors.

Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. The schematic implementation mode of the present invention and its description are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual research and development stage.

The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0034] The traditional motor rotor dispensing device has a stationary rotor and the dispensing head can only dispense glue along a fixed path, resulting in uneven glue application, excessive accumulation in some areas, insufficient accumulation in other areas, and an uneven glue layer. This not only affects the dynamic balance performance and bonding strength of the rotor, but also reduces the overall performance and life of the motor. In addition, the device has difficulty in processing complex workpieces and cannot meet the production requirements of high-precision motor rotors.

[0035] Embodiment 1:

[0036] like Figure 1 to Figure 2 As shown, a rotor assembly and glue dispensing integrated device for a high-speed brushless motor, the rotor is composed of a rotating shaft and a magnetic steel, the device also includes a frame 1, and two vibration plates 2 are arranged on the frame 1, wherein the workpiece in one vibration plate 2 is a rotating shaft, and the workpiece in the other vibration plate 2 is a magnetic steel; each vibration plate 2 is connected to a conveying mechanism; the frame 1 is also provided with a rotating shaft clamping mechanism and a magnetic steel clamping mechanism, and the rotating shaft clamping mechanism and the magnetic steel clamping mechanism can move on the frame 1, so that the magnetic steel is sleeved on the outer edge of the rotating shaft. The frame 1 is also provided with a glue dispensing mechanism, which is used to dispense glue on the sleeved rotor.

[0037] The vibration plate 2 is the core component of the automatic feeding. It arranges the rotating shaft and magnetic steel in an orderly manner through vibration and conveys them to the conveying pipe 3 to ensure the continuity and stability of the feeding. The conveying mechanism (conveyor pipe 3) is responsible for conveying the workpiece from the vibration plate 2 to the placement table 302. Its design must ensure that the workpiece does not get stuck or fall during the conveying process. The rotating shaft clamping mechanism and the magnetic steel clamping mechanism are used to clamp and move the rotating shaft and magnetic steel respectively. The clamps and slides thereon cooperate with the guide rails to achieve precise alignment and movement of the workpiece. The dispensing mechanism is responsible for automatically dispensing glue on the assembled rotor.

[0038] The conveying mechanism includes a conveying pipe 3 arranged on the vibration plate 2, one end of the conveying pipe 3 is connected to the interior of the vibration plate 2, and the other end of the conveying pipe 3 is connected to a placement table 302, on which a loading mechanism is arranged.

[0039] The vibrating plate 2 conveys the workpiece to the conveying tube 3, and the conveying tube 3 conveys the workpiece to the loading mechanism on the placement table 302. The loading mechanism conveys the workpiece from the conveying tube 3 to the guide block 305 through components such as the push plate 303 and the push rod 304, thereby achieving precise positioning of the workpiece. Compared with traditional manual handling, this design realizes automatic conveying and loading of workpieces, avoids the errors and risks caused by manual handling, and significantly improves production efficiency. At the same time, the coordinated use of the conveying tube 3 and the loading mechanism ensures the stability of the workpiece during the conveying and loading process, and improves the accuracy of subsequent assembly and dispensing.

[0040] The loading mechanism includes a push plate 303, a push rod 304, a guide block 305, a primary cylinder and a secondary cylinder; the push plate 303 is perpendicular to the conveying pipe 3, and the push rod 304 is parallel to the conveying pipe 3; the end of the push plate 303 is connected to the primary cylinder, and the end of the push rod 304 is connected to the secondary cylinder; when the workpiece falls from the conveying pipe 3 to the placement table 302, the primary cylinder starts, and pushes the workpiece to the end of the push rod 304 away from the secondary cylinder through the push plate 303, and the secondary cylinder starts, and pushes the workpiece into the guide block 305 through the push rod 304.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the improved scheme of this embodiment also has, the shaft clamping mechanism includes a shaft clamp 4, a shaft clamp 403, a first slide 401 and a first guide rail 402, the shaft clamp 403 is arranged on the shaft clamp 4, the shaft clamp 4 is arranged on the first slide 401, the first guide rail 402 is arranged on the frame 1, and the first slide 401 is slidably connected to the first guide rail 402; the magnetic steel clamping mechanism includes a magnetic steel clamp 5, a magnetic steel clamp 505, a second slide 501 and a second guide rail 502, the magnetic steel clamp 505 is arranged on the magnetic steel clamp 5, the magnetic steel clamp 5 is arranged on the second slide 501, the second guide rail 502 is arranged on the frame 1, and the second slide 501 is slidably connected to the second guide rail 502; the first guide rail 402 and the second guide rail 502 are arranged in parallel; the magnetic steel clamp 5 is provided with a telescopic mechanism, the telescopic mechanism is used to move the magnetic steel clamp 505 in the direction of the shaft clamp 403.

[0042] The shaft clamp 4 and the shaft chuck 403 are used to clamp the shaft, and the first slide 401 and the first guide rail 402 cooperate to achieve the precise movement of the shaft clamp 4 on the frame 1. The magnetic steel clamp 5 and the magnetic steel chuck 505 are used to clamp the magnet, and the second slide 501 and the second guide rail 502 cooperate to achieve the precise movement of the magnetic steel clamp 5 on the frame 1. The telescopic mechanism (first cylinder 503) is used to push the magnetic steel chuck 505 to move axially and insert the magnet into the outer edge of the shaft. The shaft clamping mechanism and the magnetic steel clamping mechanism clamp the shaft and the magnet respectively, and through the cooperation of the slide and the guide rail, the precise alignment and movement of the two are achieved. The telescopic mechanism pushes the magnetic steel chuck 505 to move axially and accurately inserts the magnet into the outer edge of the shaft to complete the rotor assembly.

[0043] The solution of this application realizes the one-time completion of rotor assembly and dispensing through a fully automated design. The solution uses a vibration plate to automatically feed, a clamping assembly to automatically clamp and move the workpiece, a dispensing mechanism to automatically dispense, and a transfer mechanism to automatically transport. The entire process does not require manual intervention. This not only greatly improves production efficiency, but also avoids the errors and risks caused by manual operation, ensuring the consistency of quality of each dispensing. In addition, completing assembly and dispensing at one time also simplifies the production process, reduces equipment footprint and labor costs.

[0044] like Figure 4 As shown, the improvement scheme of this embodiment is that the dispensing mechanism includes a column 6 arranged on the frame 1, one end of the column 6 is connected to the frame 1, and the other end of the column 6 is provided with a second cylinder 603; a second piston rod 604 in the second cylinder 603, the outer end of which is connected to a dispensing head 601, and the dispensing head 601 is provided with a dispensing tube 602, and the second cylinder 603 can drive the dispensing tube 602 to move in a direction perpendicular to the rotating shaft chuck 403.

[0045] The column 6 is used to support the dispensing head 601, and the second cylinder 603 drives the dispensing head 601 to move in a direction perpendicular to the rotating shaft. The glue outlet pipe 602 on the dispensing head 601 is responsible for evenly applying the glue to the contact part between the rotating shaft and the magnetic steel. The dispensing mechanism drives the dispensing head 601 to move perpendicular to the rotating shaft through the second cylinder 603, and automatically dispenses glue to the assembled rotor. The dispensing pipe 602 evenly applies the glue to the contact part between the rotating shaft and the magnetic steel. Compared with traditional manual dispensing, this design realizes automatic dispensing of the rotor. The dispensing head 601 can flexibly adjust the position and angle to ensure that the glue is evenly applied, thereby improving the dispensing accuracy and product quality.

[0046] Another improvement to this embodiment is that the telescopic mechanism includes a first cylinder 503 disposed on the magnetic steel clamp 5, a first piston rod 504 in the first cylinder 503, an outer end of which is connected to the magnetic steel chuck 505, and the first piston rod 504 can push the magnetic steel chuck 505 to move along the axial length of the first piston rod 504, so that the magnetic steel sleeve is on the outer edge of the rotating shaft.

[0047] After the magnetic steel clamp 5 clamps the magnetic steel, the first cylinder 503 is started, and the first piston rod 504 pushes the magnetic steel clamp 505 to move axially, and the magnetic steel is accurately inserted into the outer edge of the shaft to complete the rotor assembly. Compared with the traditional manual insertion method, the telescopic mechanism realizes automatic and accurate insertion of the magnetic steel.

[0048] Another improvement to this embodiment is that a rotating mechanism is provided on the rotating shaft clamp 4, and the rotating mechanism includes a motor and a belt 405 provided on the rotating shaft clamp 4. The motor can rotate the rotating shaft clamp 403 through the belt 405, so that the glue outlet hose 602 can be evenly dispensed along the outer edge of the rotating shaft.

[0049] The speed and direction of rotation of the motor need to be precisely controlled to ensure that the rotor can rotate smoothly and evenly during the dispensing process. The shaft chuck 403 is fixedly connected to the shaft, and the rotation of the rotor is driven by the shaft chuck 403. After the shaft fixture 4 clamps the shaft, the rotating mechanism is started, and the motor drives the shaft chuck 403 to rotate through the belt 405, so that the rotor rotates during the dispensing process. The dispensing mechanism dispenses glue while the rotor rotates, and the glue outlet tube 602 evenly applies the glue to the contact area between the shaft and the magnet. Compared with the traditional fixed dispensing method, this rotating dispensing solution achieves uniform application of glue, avoids the problem of uneven glue accumulation, improves the dynamic balance performance and bonding strength of the rotor, and ultimately improves the overall performance and service life of the motor.

[0050] Another improvement to this embodiment is that a support plate 8 and a transfer mechanism are provided on the frame 1, one end of the support plate 8 is connected to the frame 1, and a conveyor belt 801 is provided on the other end of the support plate 8. The transfer mechanism can transport the rotor with glue dispensing completed to the conveyor belt 801.

[0051] After the dispensing is completed, the transfer mechanism is started, and the third cylinder 704 drives the claw head 703 to move perpendicular to the rotation axis to grab the rotor after the dispensing is completed. The cross arm 701 drives the claw body 706 to move, and the rotor is placed on the conveyor belt 801, and the conveyor belt 801 transports the rotor to the subsequent station.

[0052] like Figure 5 As shown, the improved scheme of this embodiment is that the transfer mechanism includes a body 7 arranged on the frame 1, one end of the body 7 is connected to the frame 1, and the other end of the body 7 is provided with a cross arm 701, and the cross arm 701 is perpendicular to the body 7; the cross arm 701 is provided with a third guide rail 702 arranged along the length direction of the cross arm 701, and a claw body 706 is slidably provided on the third guide rail 702, and the claw body 706 is provided with a third cylinder 704 and a claw head 703; the third piston rod 705 in the third cylinder 704, the outer end of which passes through the claw body 706 and is connected to the claw head 703, and the third piston rod 705 can drive the claw head 703 to move in a direction perpendicular to the rotating shaft chuck 403 to grab the rotor.

[0053] The body 7 is mounted on the frame 1 as a support and motion base for the entire transfer mechanism. The cross arm 701 is perpendicular to the body 7, and a third guide rail 702 is arranged along the length direction to guide the sliding of the claw body 706. The claw body 706 slides on the third guide rail 702 to achieve horizontal movement.

[0054] The third cylinder 704 is mounted on the claw body 706, and its piston rod is connected to the claw head 703, which is used to drive the claw head 703 to move in a direction perpendicular to the rotation axis, so as to grab or release the rotor. The claw head 703 is a component that directly contacts the rotor, and its design needs to adapt to the shape of the rotor to ensure that the grip is firm and does not damage the rotor.

[0055] The claw body 706 slides on the third guide rail 702 to move the rotor horizontally above the conveyor belt 801. Then, the third cylinder 704 moves in the opposite direction, and the claw head 703 moves upward to release the rotor onto the conveyor belt 801. The conveyor belt 801 transports the rotor to a subsequent station for subsequent processing or packaging.

[0056] Compared with traditional manual handling, the transfer mechanism realizes automatic grasping and transfer of the rotor, simplifies the operation steps and improves production efficiency. At the same time, the precise control of the third cylinder 704 and the claw head 703 ensures the stability of the rotor during grasping and releasing, avoiding errors and damage risks caused by manual operation.

[0057] Working process:

[0058] 1. Automatic loading: The vibration plate 2 is started to transport the rotating shaft and the magnetic steel to the corresponding conveying pipe 3 in order. The conveying pipe 3 transports the rotating shaft and the magnetic steel to the loading mechanism on the placement table 302.

[0059] 2. Workpiece loading and positioning: The push plate 303 of the loading mechanism is driven by the primary cylinder to push the rotating shaft or magnetic steel to the position of the push rod 304.

[0060] The push rod 304 is driven by the secondary cylinder to push the workpiece into the guide block 305 to achieve accurate positioning of the workpiece.

[0061] 3. Automatic clamping and assembly: The shaft clamping mechanism and the magnetic steel clamping mechanism clamp the shaft and the magnetic steel respectively. The shaft clamp 4 and the magnetic steel clamp 5 move with the cooperation of the slide and the guide rail to align the magnetic steel with the shaft. The telescopic mechanism (first cylinder 503) on the magnetic steel clamp 5 is started to push the magnetic steel clamp 505 to move axially, accurately insert the magnetic steel into the outer edge of the shaft, and complete the rotor assembly.

[0062] 4. Automatic dispensing: The second cylinder 603 of the dispensing mechanism drives the dispensing head 601 to move perpendicular to the shaft direction and align with the contact part between the shaft and the magnet. The rotating mechanism (motor and belt 405) starts, driving the shaft clamp 403 to rotate, so that the rotor rotates. The dispensing head 601 dispenses glue while the rotor rotates, ensuring that the glue is evenly applied to the contact part between the shaft and the magnet.

[0063] 5. Automatic transfer: After the dispensing is completed, the transfer mechanism is activated. The third cylinder 704 drives the claw head 703 to move perpendicular to the rotation axis and grab the rotor after the dispensing is completed. The claw body 706 slides on the third guide rail 702 and moves the rotor horizontally above the conveyor belt 801. The third cylinder 704 moves in the opposite direction, and the claw head 703 moves upward to release the rotor onto the conveyor belt 801. The conveyor belt 801 transports the rotor to the subsequent station for subsequent processing or packaging.

[0064] The solution of the present application adopts a high-precision mechanical structure and an automated control system to ensure high assembly accuracy. The shaft clamping assembly and the magnetic steel clamping assembly cooperate with precise slides and guide rails to achieve high-precision movement and alignment of the workpiece. The telescopic mechanism can accurately control the axial movement distance of the magnetic steel chuck to ensure that the magnetic steel can be accurately inserted into the outer edge of the shaft. In addition, the second cylinder and the dispensing head of the dispensing mechanism have extremely high positioning accuracy and repeatability, ensuring that the position and amount of glue are accurate each time. Therefore, this solution can meet the stringent tolerance requirements of 0.001-0.01mm between the shaft and the hole, and achieve high-precision rotor assembly.

[0065] Embodiment 2:

[0066] like Figure 5 As shown, the length direction of the cross arm 701 is parallel to the length direction of the conveyor belt 801.

[0067] When the third cylinder 704 drives the claw head 703 to grab the rotor, the claw body 706 slides on the cross arm 701 along the third guide rail 702, and moves the rotor horizontally to just above the conveyor belt 801. Then, the third cylinder 704 moves in the opposite direction, and the claw head 703 moves upward to release the rotor onto the conveyor belt 801. Since the cross arm 701 is parallel to the conveyor belt 801, the rotor can be accurately placed on the conveyor belt 801 to avoid deviation or falling. Compared with traditional manual handling, this design simplifies the rotor transfer path, improves the efficiency and accuracy of rotor transportation, and also reduces the equipment footprint and improves space utilization.

[0068] The solution of this application is specially designed for the high-precision and high-efficiency requirements of high-speed brushless motors for rotor assembly. High-speed brushless motors require extremely high assembly accuracy between the shaft and the magnetic steel hole, and the glue must be evenly applied to ensure the dynamic balance performance and bonding strength of the rotor when rotating at high speed. This solution fully meets the high-precision, high-consistency and high-efficiency requirements of high-speed brushless motors for rotor assembly through a precise fixture mechanism, an automated dispensing system and a high-precision rotary dispensing design.
