Description

TECHNICAL FIELD

[0001] The utility model relates to motor rotor manufacturing technical field especially relates to a rotor assembly, point gum integration device of high -speed brushless motor. BACKGROUND

[0002] In the manufacturing process of motor rotor, point gum is a vital link. Rotor is usually assembled by rotating shaft and magnetic steel parts, and these parts need to be bonded by glue to ensure the stability and reliability of the rotor in high speed rotation. Glue not only plays a fixed role, but also can prevent the magnetic steel from loosening or falling off when the rotor is running at high speed, so as to avoid the vibration, noise and even damage the internal structure of the motor during the working process. In addition, uniform application of glue can also improve the dynamic balance performance of the rotor, reduce the energy loss and heat generation of the motor during operation, and prolong the service life of the motor.

[0003] Traditional point gum device usually adopts manual or semi-automatic assembly method, the precision of clamp and guide rail is low, and lacks precise positioning mechanism, which is easy to cause error of workpiece in clamping and moving process, and cannot meet the requirements of high precision assembly. For example, the maximum tolerance of rotating shaft and magnetic steel hole is only 0.001-0.01mm, and traditional device is difficult to guarantee such high assembly precision, which leads to unstable assembly quality and affects product performance. In addition, due to the lack of automatic conveying, clamping, alignment and point gum integration design, the assembly and point gum process cannot be continuously carried out, and the traditional device cannot realize one-time automatic completion of assembly and point gum work. Traditional motor rotor point gum device, because the rotor is static in the process of point gum, the point gum head can only carry out point gum along the fixed path, the glue cannot be uniformly applied in the contact part of rotating shaft and magnetic steel, which leads to excessive accumulation of glue in some areas, and insufficient application in other areas, forming uneven glue layer, affecting the dynamic balance performance and bonding strength of the rotor, and finally affecting the overall performance and service life of the motor. In addition, it also limits the point gum precision of traditional point gum machine on complex structure workpiece, and cannot meet the production demand of high precision motor rotor.

[0041] As shown in Figure 2 , Figure 3 and Figure 4 , the improved scheme of the embodiment further includes a shaft clamping mechanism including a shaft clamp 4, a shaft chuck 403, a first sliding table 401 and a first guide rail 402. The shaft chuck 403 is arranged on the shaft clamp 4, the shaft clamp 4 is arranged on the first sliding table 401, the first guide rail 402 is arranged on the rack 1, and the first sliding table 401 and the first guide rail 402 are slidingly connected. A magnetic steel clamping mechanism includes a magnetic steel clamp 5, a magnetic steel chuck 505, a second sliding table 501 and a second guide rail 502. The magnetic steel chuck 505 is arranged on the magnetic steel clamp 5, the magnetic steel clamp 5 is arranged on the second sliding table 501, the second guide rail 502 is arranged on the rack 1, and the second sliding table 501 and the second guide rail 502 are slidingly connected. 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 for moving the magnetic steel chuck 505 towards the shaft chuck 403.

[0042] The rotating shaft clamp 4 and the rotating shaft clamp head 403 are used to clamp the rotating shaft, the first sliding table 401 and the first guide rail 402 are matched to realize the accurate movement of the rotating shaft clamp 4 on the rack 1. The magnetic steel clamp 5 and the magnetic steel clamp head 505 are used to clamp the magnetic steel, the second sliding table 501 and the second guide rail 502 are matched to realize the accurate movement of the magnetic steel clamp 5 on the rack 1. The telescopic mechanism (the first air cylinder 503) is used to push the magnetic steel clamp head 505 to move along the axial direction, and the magnetic steel is sleeved on the outer edge of the rotating shaft. The rotating shaft clamping mechanism and the magnetic steel clamping mechanism clamp the rotating shaft and the magnetic steel respectively, and realize the accurate alignment and movement of the two through the cooperation of the sliding table and the guide rail. The telescopic mechanism pushes the magnetic steel clamp head 505 to move along the axial direction, and the magnetic steel is accurately sleeved on the outer edge of the rotating shaft, and the rotor assembly is completed.

[0043] The scheme of the present application realizes the one-time completion of rotor assembly and glue dispensing through full automation. The scheme adopts a vibrating disc automatic feeding, a clamping assembly automatic clamping and moving workpieces, a glue dispensing mechanism automatic glue dispensing, and a transfer mechanism automatic transfer, and the whole process does not need manual intervention. This not only greatly improves the production efficiency, but also avoids the errors and risks brought by manual operation, and guarantees the quality consistency of each glue dispensing. In addition, the one-time completion of assembly and glue dispensing also simplifies the production process, reduces the equipment floor space and labor cost.

[0044] As shown in Figure 4 The improved scheme of the present embodiment further has that the glue dispensing mechanism includes a stand 6 provided on the rack 1, one end of the stand 6 is connected to the rack 1, and the other end of the stand 6 is provided with a second air cylinder 603; a second piston rod 604 in the second air cylinder 603, the outer end of the second piston rod 604 is connected with a glue dispensing head 601, the glue dispensing head 601 is provided with a glue outlet pipe 602, and the second air cylinder 603 can drive the glue outlet pipe 602 to move in a direction perpendicular to the rotating shaft clamp head 403.

[0045] The stand 6 is used to support the glue dispensing head 601, and the second air cylinder 603 drives the glue dispensing head 601 to move in a direction perpendicular to the rotating shaft. The glue outlet pipe 602 on the glue dispensing head 601 is responsible for uniformly applying glue to the contact part between the rotating shaft and the magnetic steel. The glue dispensing mechanism drives the glue dispensing head 601 to move in a direction perpendicular to the rotating shaft through the second air cylinder 603, and automatically dispenses glue to the assembled rotor. The glue outlet pipe 602 uniformly applies glue to the contact part between the rotating shaft and the magnetic steel. Compared with the traditional manual glue dispensing, the design realizes the automatic glue dispensing of the rotor, the glue dispensing head 601 can be flexibly adjusted in position and angle, ensures the uniform application of glue, and improves the glue dispensing precision and product quality.

[0046] The improved scheme of the present embodiment further has that the telescopic mechanism includes a first air cylinder 503 provided on the magnetic steel clamp 5, a first piston rod 504 in the first air cylinder 503, the outer end of the first piston rod 504 is connected to the magnetic steel clamp head 505, and the first piston rod 504 can push the magnetic steel clamp head 505 to move along the axial length of the first piston rod 504, so that the magnetic steel is sleeved on the outer edge of the rotating shaft.

[0047] After the magnetic steel is clamped by the magnetic steel clamp 5, the first cylinder 503 is started, and the first piston rod 504 pushes the magnetic steel clamp head 505 to move in the axial direction, so that the magnetic steel is accurately sleeved into the outer edge of the rotating shaft, and the rotor assembly is completed. Compared with the traditional manual sleeving mode, the telescopic mechanism realizes automatic and accurate sleeving of the magnetic steel.

[0048] The improved scheme of the embodiment further includes that the rotating mechanism is arranged on the rotating shaft clamp 4, and the rotating mechanism includes a motor and a belt 405 arranged on the rotating shaft clamp 4. The motor can rotate the rotating shaft clamp head 403 through the belt 405, so that the glue pipe 602 can uniformly glue along the outer edge of the rotating shaft.

[0049] The rotating speed and rotating direction of the motor need to be accurately controlled to ensure that the rotor can rotate smoothly and uniformly during the glue dispensing process. The rotating shaft clamp head 403 is fixedly connected with the rotating shaft, and the rotation of the rotor is driven by the rotating shaft clamp head 403. After the rotating shaft is clamped by the rotating shaft clamp 4, the rotating mechanism is started, the motor drives the rotating shaft clamp head 403 to rotate through the belt 405, so that the rotor rotates during the glue dispensing process. The glue dispensing mechanism dispenses glue while the rotor rotates, and the glue pipe 602 uniformly applies glue to the contact part between the rotating shaft and the magnetic steel. Compared with the traditional fixed glue dispensing mode, the rotating glue dispensing scheme realizes uniform application of glue, avoids the problem of uneven accumulation of glue, improves the dynamic balance performance and bonding strength of the rotor, and finally improves the overall performance and service life of the motor.

[0050] The improved scheme of the embodiment further includes that the support plate 8 and the transfer mechanism are arranged on the rack 1. One end of the support plate 8 is connected to the rack 1, and the other end of the support plate 8 is provided with a conveying belt 801. The transfer mechanism can transport the rotor after glue dispensing to the conveying belt 801.

[0051] After the glue dispensing is completed, the transfer mechanism is started, the third cylinder 704 drives the claw head 703 to move perpendicularly to the direction of the rotating shaft, and the rotor after the glue dispensing is gripped. The horizontal arm 701 drives the claw body 706 to move, and the rotor is placed on the conveying belt 801, and the conveying belt 801 transports the rotor to the subsequent station.

[0052] As shown in Figure 5 The improved scheme of the embodiment further includes that the transfer mechanism includes a machine body 7 arranged on the rack 1. One end of the machine body 7 is connected to the rack 1, and the other end of the machine body 7 is provided with a horizontal arm 701, and the horizontal arm 701 is perpendicular to the machine body 7. The third guide rail 702 is arranged on the horizontal arm 701 in the length direction of the horizontal arm 701. The claw body 706 is slidably arranged on the third guide rail 702. The third cylinder 704 and the claw head 703 are arranged on the claw body 706. The third piston rod 705 in the third cylinder 704 penetrates through the claw body 706 and is connected to the claw head 703 at the outer end. The third piston rod 705 can drive the claw head 703 to move in the direction perpendicular to the rotating shaft clamp head 403, and grip the rotor.

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

[0054] The third cylinder 704 is installed on the claw body 706, and its piston rod is connected to the claw head 703 for driving the claw head 703 to move vertically to the rotation axis direction, so as to grab or release the rotor. The claw head 703 is the part directly contacting the rotor, and its design needs to adapt to the shape of the rotor to ensure firm grabbing and no damage to 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 reverses the movement, 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.

[0056] Compared with traditional manual handling, the transfer mechanism realizes automatic grabbing and transfer of the rotor, simplifies the operation steps, and improves the 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 the grabbing and releasing process, avoiding the errors and damage risks brought by manual operation.

[0057] Working process:

[0058] 1. Automatic feeding: the vibration disc 2 starts to orderly transport the rotation shaft and the magnetic steel into the corresponding conveying pipe 3. The conveying pipe 3 transports the rotation 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 rotation shaft or the magnetic steel to the push rod 304 position.

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

[0061] 3. Automatic clamping and assembly: the rotation shaft clamping mechanism and the magnetic steel clamping mechanism clamp the rotation shaft and the magnetic steel respectively. The rotation shaft clamp 4 and the magnetic steel clamp 5 move under the cooperation of the sliding table and the guide rail to align the magnetic steel with the rotation shaft. The extension mechanism (first cylinder 503) on the magnetic steel clamp 5 starts to push the magnetic steel clamp head 505 to move axially, accurately sleeves the magnetic steel into the outer edge of the rotation shaft, and completes the rotor assembly.

[0062] 4. Automatic dispensing: The second cylinder 603 of the dispensing mechanism drives the dispensing head 601 to move vertically relative to the rotation axis, aligning with the contact position of the rotation axis and the magnetic steel. The rotation mechanism (motor and belt 405) is started to drive the rotation axis 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 position of the rotation axis and the magnetic steel.

[0063] 5. Automatic transfer: After dispensing is completed, the transfer mechanism is started. The third cylinder 704 drives the claw head 703 to move vertically relative to the rotation axis, grabbing the rotor after dispensing is completed. The claw body 706 slides on the third guide rail 702 to move the rotor horizontally above the conveyor belt 801. The third cylinder 704 moves in reverse, 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 work station for subsequent processing or packaging.

[0064] The scheme of the present application adopts high-precision mechanical structure and automatic control system, ensuring high assembly precision. The rotation axis clamping assembly and the magnetic steel clamping assembly are matched through precise sliding table and guide rail, realizing high-precision movement and alignment of the workpiece. The telescopic mechanism can accurately control the axial movement distance of the magnetic steel clamp, ensuring that the magnetic steel can be accurately and correctly fitted into the outer edge of the rotation axis. In addition, the second cylinder and the dispensing head of the dispensing mechanism have very high positioning accuracy and repeatability, ensuring that the position and amount of glue for each dispensing are accurate and correct. Therefore, the scheme can meet the strict tolerance requirement of 0.001-0.01mm between the shaft and the hole, realizing high-precision rotor assembly.

[0065] Example 2:

[0066] As shown in Figure 5 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 to move the rotor horizontally above the conveyor belt 801. Then, the third cylinder 704 moves in reverse, 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 and correctly placed on the conveyor belt 801, avoiding deviation or falling. Compared with traditional manual handling, this design simplifies the rotor transfer path, improves the efficiency and accuracy of rotor transfer, and also reduces the equipment floor area, improving the space utilization.

[0068] The scheme of the application is specially designed for the high-precision and high-efficiency requirement of rotor assembly of high-speed brushless motor. The high-speed brushless motor requires high assembly precision of the rotating 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 in high-speed rotation. The scheme fully meets the high-precision, high-consistency and high-efficiency requirement of rotor assembly of high-speed brushless motor through the precise clamp mechanism, automatic dispensing system and high-precision rotary dispensing design.
