Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly devices, and particularly relates to a feeding mechanism for rotor magnetic sheets of a motor. Background Technique

[0002] A motor consists of two parts, a rotor and a stator, and realizes energy conversion through their interaction. According to different rotation methods, the motor rotor can be divided into an inner rotor rotation method and an outer rotor rotation method. In the inner rotor rotation method, the core in the middle of the motor is the rotating body, outputting torque (motor) or receiving energy (generator). In the outer rotor rotation method, the outer body of the motor is the rotating body, which facilitates applications in various scenarios.

[0003] The motor rotor is an important part of the motor. Its working principle is based on the laws of electromagnetic induction and the interaction of magnetic fields. When the stator winding is energized, a rotating magnetic field is generated, which interacts with the conductors (or permanent magnets) in the rotor to generate an electromagnetic force, causing the rotor to start rotating. In a motor, the rotor outputs mechanical energy through rotation; in a generator, the rotor converts mechanical energy into electrical energy through rotation.

[0004] The common structure of a motor rotor includes a rotor housing and rotor magnetic sheets arranged on the inner wall of the rotor housing. Due to the arc-shaped outer shape of the rotor magnetic sheets, in the current rotor assembly process, there is no suitable feeding mechanism to independently and batch-feed the rotor magnetic sheets for the rotor ferromagnetic process. Instead, manual picking is mostly used, which severely restricts the assembly efficiency of the rotor.

[0005] Therefore, a new technical solution is urgently needed to solve this technical problem. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the problems of the above-mentioned prior art, and provides a feeding mechanism for rotor magnetic sheets of a motor, which is used to solve the technical problem that in the current rotor assembly process, there is no suitable feeding mechanism to automatically feed the rotor magnetic sheets with an arc-shaped outer shape, and the assembly efficiency is low when manual operation is used.

[0007] The above purpose is achieved through the following technical solutions:

[0008] A feeding mechanism for rotor magnetic sheets of a motor includes a linear feeding component. The linear feeding component includes a feeding end and a discharging end. A material blocking component is arranged at the discharging end, and a rotor magnetic sheet lifting component is arranged below the material blocking component, which is used to eject the rotor magnetic sheet staying at the material blocking component, and the material transferring component arranged above the material blocking component is used to transfer the rotor magnetic sheet.

[0009] Further, the linear feeding assembly includes a belt, a transfer table for driving the belt, and material transfer stoppers disposed on both sides of the belt. The same ends of the two material transfer stoppers abut against the material blocking assembly.

[0010] Further, the transfer table is a linear vibratory feeder.

[0011] Further, the material blocking assembly includes a C-shaped material blocking block disposed at the discharging end. The two ends of the C-shaped material blocking block are respectively fixedly connected to the transfer table, and a material blocking through groove through which the belt can pass is provided at the bottom. The inner side of the C-shaped material blocking block forms a material blocking position, and a jacking post through hole through which the jacking post of the rotor magnet piece jacking assembly can penetrate is provided in the transfer table corresponding to the material blocking position.

[0012] Further, there are two jacking post through holes, which are symmetrically arranged on both sides of the belt. Correspondingly, there are two jacking posts, which can respectively move vertically through the jacking post through holes and act on the bottom end of the rotor magnet piece.

[0013] Further, the rotor magnet piece jacking assembly includes support columns symmetrically arranged on both sides of the transfer table. Lifting guide sleeves are movably sleeved on the support columns. A guide plate is arranged between the two lifting guide sleeves, and a vertical jacking post is arranged on the guide plate. The guide plate is connected to the piston of a lifting cylinder arranged below.

[0014] Further, an upper pressing plate is further arranged on the top of the C-shaped material blocking block, and a limiting through groove corresponding to the outer shape of the rotor magnet piece is provided on the upper pressing plate.

[0015] Further, the material transfer assembly includes a material transfer support column arranged on one side of the linear feeding assembly. A material transfer support plate is connected to the material transfer support column. A transverse movement driving assembly is arranged on the material transfer support plate. A moving seat is connected to the transverse movement driving assembly. A cylinder jaw with the jaw facing downward is arranged on the moving seat, and a clamping plate is arranged outside the cylinder jaw.

[0016] Further, a pair of lifting push rods is further arranged on the moving seat. A push piece is arranged at the top end of the lifting push rod and is connected to the piston of a lifting push rod cylinder. A pressing head is arranged at the bottom end of the lifting push rod.

[0017] Further, a pair of push rod sleeve seats for sleeving the lifting push rods is arranged on the moving seat.

[0018] The rotor magnet feeding mechanism for a motor provided by the present utility model limits and conveys the rotor magnets through a linear feeding assembly, and conveys them to the material blocking assembly in a specified position and posture; the blocked rotor magnets are lifted by the rotor magnet lifting assembly. After they are ejected from the material blocking position, the transfer assembly picks up and transfers the rotor magnets, finally realizing the feeding to the next working station. This mechanism not only has a simple structure and occupies a small space, but also can achieve precise conveying, material blocking, lifting and clamping transfer of the rotor magnets. Compared with the traditional manual feeding operation, it has a high degree of automation and can effectively improve the feeding efficiency of the rotor magnets in the motor assembly process.

[0031] The following further describes the present utility model in detail with reference to the drawings and embodiments. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0032] As shown in Figures 1 to 3 A feeding mechanism for the rotor magnetic sheet of a motor includes a linear feeding component 1. The linear feeding component 1 includes a feeding end 101 and a discharging end 102. A material blocking component 2 is arranged at the discharging end 102 for limiting and blocking the rotor magnetic sheet 5 traveling to this position, so that it temporarily stays at this position. A rotor magnetic sheet lifting component 3 is arranged below the material blocking component 2 for ejecting the rotor magnetic sheet 5 staying at the material blocking component 2, and the material transfer of the rotor magnetic sheet 5 is carried out by a material transfer component 4 arranged above the material blocking component 2, so as to continuously carry out subsequent processes;

[0033] It should be noted that in this embodiment, the linear feeding component 1 is connected to the bottom plate 107 through a bracket 106 to achieve the purpose of elevation.

[0034] In this embodiment, the linear feeding component 1 includes a belt 103 and a transfer table 104 for driving the belt 103, and material transfer stop strips 108 arranged on both sides of the belt 103. The two material transfer stop strips 108 are used to limit the two ends of the rotor magnetic sheet 5 in the head - to - tail direction, so that it keeps the same pose and is conveyed and fed on the belt 103. The same ends of the two material transfer stop strips 108 are in contact with the material blocking component 2, so as to better and stably convey the rotor magnetic sheet 5 into the material blocking component 2.

[0035] As an optimization of the transfer table 104, the transfer table 104 is a linear vibration feeder. The linear vibration feeder with a vibration function is used to vibrate and transfer the rotor magnetic sheets 5 scattered on the belt 103, and correct their poses, so that they keep the same pre - determined pose after entering the material blocking component 2, and then it is convenient for the rotor magnetic sheet lifting component 3 to perform the ejecting operation.

[0036] As Figure 3 and 4 shown, in this embodiment, the material blocking assembly 2 includes a C-shaped material blocking block 201 disposed at the discharge end 102. Both ends of the C-shaped material blocking block 201 are fixedly connected to the transfer table 104, and a material blocking through groove 202 through which the belt 103 can pass is provided at the bottom;

[0037] The inner side of the C-shaped material blocking block 201 forms a material blocking position 203, and a jacking post through hole 105 through which the jacking post 301 of the rotor magnet piece jacking assembly 3 can penetrate is formed in the transfer table 104 corresponding to the material blocking position 203.

[0038] Specifically, in this embodiment, the C-shaped material blocking block 201 can limit and block the rotor magnet piece 5 located at the front end conveyed on the belt 103 at the material blocking position 203. After the rotor magnet piece 5 completely enters the specified position, the rotor magnet piece jacking assembly 3 is triggered to work. The rotor magnet piece jacking assembly 3 drives the jacking post 301 to jack the rotor magnet piece 5 to a specified height, so that the material transfer assembly 4 can clamp and transfer the rotor magnet piece 5.

[0039] In this embodiment, there are 2 jacking post through holes 105, which are symmetrically arranged on both sides of the belt 103;

[0040] Correspondingly, there are 2 jacking posts 301, which can move vertically through the jacking post through holes 105 respectively, and can act on the bottom end of the rotor magnet piece 5 to stably jack it and make it move vertically upward along the material blocking position 203.

[0041] In addition, an upper pressing plate 204 is further provided on the top of the C-shaped material blocking block 201. A limiting through groove 205 corresponding to the outer shape of the rotor magnet piece 5 is formed in the upper pressing plate 204. The limiting through groove 205 can limit and guide the two ends of the rotor magnet piece 5, and further ensure that it will not be toppled when being jacked up and rising.

[0042] In this embodiment, the rotor magnet lifting assembly 3 includes support columns 302 symmetrically arranged on both sides of the transfer table 104. The top of the support column 302 is fixedly connected to the transfer table 104 through a side plate 303. A lifting guide sleeve 304 is movably sleeved on the support column 302. A guide plate 305 is arranged between the two lifting guide sleeves 304. A vertically arranged lifting column 301 is arranged on the guide plate 305. The guide plate 305 is connected to the piston of a lifting cylinder 306 arranged below. Through the drive of the lifting cylinder 306, the lifting column 301 is indirectly controlled to move vertically up and down, so as to achieve the purpose of ejecting the rotor magnet 5 located at the material blocking position 203.

[0043] After the rotor magnet 5 to be ejected is removed by the feeding of the material transfer assembly 4, the lifting cylinder 306 drives the guide plate 305 to drive the lifting column 301 to move downward. After the next rotor magnet 5 enters the material blocking position 203, the above movement is repeated to realize continuous feeding.

[0044] As Figure 5 and 6 shown, in this embodiment, the material transfer assembly 4 includes a material transfer support column 401 arranged on one side of the linear feeding assembly 1. A material transfer support plate 402 is connected to the material transfer support column 401. A transverse movement drive assembly 403 is arranged on the material transfer support plate 402. A moving seat 404 is connected to the transverse movement drive assembly 403. A cylinder jaw 405 with the jaw facing downward is arranged on the moving seat 404. A clamping plate 406 is arranged outside the cylinder jaw 405. The two clamping plates 406 can clamp the ejected rotor magnet 5, so as to complete the feeding of the rotor magnet 5 to the subsequent tooling.

[0045] In this embodiment, the transverse movement drive assembly 403 is preferably a transverse movement electric push rod, and its piston end is connected to the support plate. A transverse movement slide rail 407 is further arranged on the back of the material transfer support plate 402 to ensure that it can stably move transversely under the drive of the transverse movement electric push rod, and is used to feed the rotor magnet 5 clamped by the clamping plate 406 into the next tooling.

[0046] A pair of lifting push rods 408 are further arranged on the moving seat 404. A push piece 409 is arranged at the top end of the lifting push rod 408. The push piece 409 is connected to the piston of a lifting push rod cylinder 410. A pressing head 411 is arranged at the bottom end of the lifting push rod 408. The pressing head 411 can unload the rotor magnet 5 clamped by the clamping plate 406 downward through the drive of the lifting push rod cylinder 410.

[0047] A pair of push rod socket seats 412 capable of sleeving the lifting push rod 408 are arranged on the moving seat 404, so as to accurately guide the lifting push rod 408 and keep it running stably in the vertical direction.

[0048] The above is only to illustrate the embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
