Description

Technical Field

[0001] This utility model relates to the field of stator and rotor processing technology, specifically to an automatic stator and rotor stacking device. Background Technology

[0002] With the continuous development of automation technology, traditional stator and rotor lamination devices mostly rely on manual operation or semi-automatic equipment for the lamination process. These traditional devices generally use manual or single mechanical transmission methods to control the lamination and conveying of rotor laminations, resulting in problems such as complex structure, inconvenient operation, low work efficiency, and low precision. For example, traditional equipment often relies on manual placement of stator and rotor laminations into the lamination device, and the lamination process requires manual adjustment of pressure and displacement, which can easily lead to uneven lamination, misalignment of rotor laminations, or uneven stacking, thereby affecting product quality and production efficiency.

[0003] In addition, existing stator and rotor lamination conveying and feeding methods often employ manual or relatively simple mechanical feeding methods. This not only increases labor intensity but also fails to ensure continuous feeding and precise positioning of stator and rotor laminations, often resulting in jamming, material dropping, or uneven feeding, thus affecting the overall operating efficiency of automated production lines.

[0004] In traditional stator-rotor lamination technology, the lack of effective automated control and precise pressing methods often leads to deformation and misalignment of the stator and rotor laminations during the lamination process, resulting in unstable final lamination effects. Furthermore, existing technologies are typically not precise enough in their automatic feeding and output designs, causing discontinuous stator-rotor lamination feeding and affecting production efficiency and stability. Therefore, existing technologies fail to effectively solve the accuracy and efficiency problems in stator-rotor lamination and feeding processes. This paper researches and improves upon these existing problems to provide an automatic stator-rotor lamination device, aiming to solve the current issues and enhance practical value. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] This utility model relates to an automatic stator and rotor stacking device, mainly comprising a base, a stacking assembly, and a feeding assembly. A conveyor belt at the output end of a rotary disc is fixed on the base, and the rotary disc is mounted on the top surface of the base. A guide plate is provided on the surface of the rotary disc. The stacking assembly includes a fixed base, a transmission gear disc, a slanted guide rod, a slanted plate, and pressure pins. The slanted plate is sleeved on the surface of the slanted guide rod, and several pressure pins are movably mounted on the slanted plate. The top end of the slanted guide rod is fixedly connected to the surface of the transmission gear disc. A drive motor is fixedly mounted on the fixed base, and the output end of the motor is engaged with the surface of the transmission gear disc. The feeding assembly includes a guide seat, a drive cylinder, and a pusher head. A rotor blade storage cylinder is fixedly mounted on the surface of the guide seat. The output end of the drive cylinder is connected to the end of the pusher head for reciprocating motion.

[0007] In a preferred embodiment, this invention can be further configured such that, through a pre-designed stacking assembly, the inner pressure column head of the rotating disk is reciprocated relative to the guide rod and the swashplate during rotation, thereby achieving automatic stacking and stamping of the stator and rotor laminations. The cooperation between the swashplate and the pressure column head effectively ensures the leveling and adhesion of the stator and rotor laminations during the stacking process, thus guaranteeing the accuracy and stability of the stacking.

[0008] In a preferred embodiment, this invention can be further configured such that: the arrangement of the base and the guide seat on the radially opposing shafts of the rotary disc allows the rotor blades to fall freely within the rotor blade storage cylinder. A drive cylinder then drives a pusher head to reciprocate, precisely pushing the falling rotor and stator blades into the guide plate within the rotary disc. Under the indexing rotation of the rotary disc, the rotor and stator blades are sequentially stacked to the required quantity.

[0009] In a preferred embodiment, this invention can be further configured such that a drive motor drives the intermittent indexing rotation of the rotary disc, thereby ensuring that the stacking process of the stator and rotor laminations is carried out according to the set precision and gap angle, achieving automated and precise indexing operation. The indexing precision between the rotary disc and the guide plate ensures the neat stacking of the stator and rotor laminations.

[0010] In a preferred embodiment, this invention can be further configured such that the contact pressure between each pressure pin and the sliding guide plate is evenly distributed through the cooperation of the inclined guide rod and the inclined plate. The inclined arrangement of the inclined plate and the vertical installation of the pressure pins ensure stability during the pressing process, and the reciprocating motion of the pressure pins achieves effective leveling and bonding of the stator and rotor plates.

[0011] In a preferred embodiment, this invention can be further configured such that: a slanted guide rod is axially arranged on the surface of the rotary disk, allowing the slant disk and the pressure column head to effectively push the stator and rotor plates for automatic stacking. The addition of a counterweight helps adjust the pressure distribution of the slanted guide rod during the stacking process, thereby ensuring the stability and accuracy of the stacking process.

[0012] In a preferred embodiment, this invention can be further configured such that the pusher head can precisely slide and push the stator and rotor blades along the inner side of the material groove through the material groove opened on the guide seat, ensuring continuous feeding and stable output of the stator and rotor blades. The tight fit between the pusher head and the bottom surface of the rotor blade storage cylinder makes the material conveying process smoother, avoiding material jamming or loss, thereby ensuring the high efficiency of automatic continuous stacking of stator and rotor blades.

[0013] The beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, through the set stacking component, the inner pressure column head of the traction wheel disk is pulled to reciprocate in the rotation of the inclined guide rod and the swash plate, so as to realize the automatic stacking and stamping of the stator and rotor plates. Through the cooperation of the swash plate and the pressure column head, the flatness and fit of the stator and rotor plates are effectively ensured during the stacking process, thus ensuring the accuracy and stability of the stacking.

[0015] 2. In this utility model, the drive cylinder is used to drive the pusher head to reciprocate, thereby realizing the automatic feeding of the stator and rotor plates, ensuring the continuous feeding of the rotor plates, and the material is transferred during the rotation of the turntable, and automatically output by the output conveyor belt, realizing the automatic continuous stacking of the stator and rotor.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following is in conjunction with the appendix Figures 1-5 This invention describes an automatic stator and rotor stacking device provided by some embodiments of the present invention. Example 1

[0028] This embodiment provides an automatic stator and rotor stacking device, the structure of which is as follows:

[0029] The device consists of three main parts: a base 100, a stacking assembly 200, and a feeding assembly 300.

[0030] The base 100 is the main part of the device and has a fixed structure. The output end conveyor belt 120 is fixedly mounted on its surface and is rotatably mounted on the top surface of the base 100 via a rotary disc 110. The surface of the rotary disc 110 is provided with multiple sliding guide plates 111 for receiving rotor blades.

[0031] The stacking assembly 200 includes a fixed base 210, a transmission gear plate 220, a slanted guide rod 230, and several pressure columns 250. A slanted plate 240 is sleeved on the surface of the slanted guide rod 230, and multiple ball joints 241 are movably mounted on the slanted plate 240. The other end of each ball joint 241 is connected to a pressure column 250 in a corresponding manner.

[0032] The feeding assembly 300 includes a guide seat 310, a drive cylinder 320, and a pusher head 330, and a stator and rotor blade storage cylinder 311 is fixedly mounted on the surface of the guide seat 310. The output end of the drive cylinder 320 is connected to the end of the pusher head 330 to drive the pusher head 330 to achieve reciprocating motion.

[0033] Working principle:

[0034] The rotor blades fall freely inside the stator and rotor blade storage cylinder 311, and the pusher head 330 is driven by the drive cylinder 320 to push the falling rotor blades into the inner side of the sliding guide plate 111 of the rotary disk 110.

[0035] During the indexing rotation of the rotary disk 110, the rotor blades will follow the movement of the rotary disk 110, and the thickness of the rotary disk 110 determines the number of rotor blades stacked each time.

[0036] The device uses a motor inside the base 100 to drive the rotary disk 110 to achieve intermittent indexing rotation, and the gap angle of the rotation is the same as the gap angle of the adjacent sliding guide plate 111.

[0037] Technical features: The swashplate 240 is arranged at an angle to ensure that each ball joint 241 and the pressure column 250 can be vertically aligned and work together. The outer periphery of the pressure column 250 slides against the inner side of the guide plate 111 to ensure that the rotor blades and the pressure column 250 do not deviate from the motion trajectory when on the guide plate 111. Example 2

[0038] This embodiment, based on the technical solutions described in claims 1 to 4, further improves the structure of the automatic stator and rotor stacking device, as specifically described below:

[0039] Structural Description: This embodiment is the same as Embodiment 1, with the same basic structure. The main difference lies in the improvement of the driving part.

[0040] The inner side of the base 100 is equipped with a motor for driving the rotary disk 110 to rotate intermittently, and the output end of the motor meshes with the drive gear of the rotary disk 110. The motor control system is equipped with a precision encoder to achieve higher indexing accuracy.

[0041] The rotational index of the rotary disk 110 is completely consistent with the gap angle of the adjacent sliding guide plate 111, thereby ensuring the accuracy and consistency of the rotor lamination process.

[0042] The swash plate 240 is still arranged at an angle, while the ball joint 241 and the pressure column 250 maintain a stable fit in the vertical direction to ensure the smooth movement of the rotor blades.

[0043] Working principle:

[0044] In this embodiment, the rotor blades fall inside the stator and rotor blade storage cylinder 311 and are pushed by the reciprocating motion of the pusher head 330 driven by the drive cylinder 320, gradually entering the inner side of the sliding guide plate 111 for stacking.

[0045] The number of rotor blades stacked is determined by the thickness of the pusher head 330, and the rotary disk 110 rotates gradually according to a precise indexing angle under the drive of the motor, ensuring that the number of rotor blades entering the inner side of the guide plate 111 each time is uniform.

[0046] By precisely controlling the speed and rotation increments of the motor, this embodiment enables efficient rotor lamination in high-speed production environments.

[0047] Technical features:

[0048] Unlike Embodiment 1, this embodiment adds a precise control system for the motor, such as an encoder and servo control, to improve the stability and accuracy of the device in practical applications.

[0049] The swash plate 240 still ensures the effective cooperation between the ball joint 241 and the pressure head 250 by sloping arrangement, and ensures the stable stacking of each rotor blade.

[0050] Beneficial effects

[0051] This embodiment, through a precise motor control and indexing system, can provide a higher level of automation, ensuring the reliability and accuracy of the device during long-term operation.

[0052] The optimized design of the swash plate 240 and the pressure head 250 makes the movement of the rotor blades smoother during the stacking process and reduces the risk of jamming.

[0053] Working principle and usage process of this utility model:

[0054] During the stacking of stator and rotor laminations, after the drive cylinder 320 drives the pusher head 330 to retract, the stator and rotor laminations fall freely into the material trough of the stator and rotor lamination storage cylinder 311. The drive cylinder 320 drives the pusher head 330 to push the stator and rotor laminations along the material trough and push them into the inner side of the corresponding sliding guide plate 111. Under the indexing rotation of the rotary disk 110 and the synchronous rotation of the drive motor 211 to the inclined guide rod 230 and the inclined plate 240, the pressure column heads 250 connected to the inclined plate 240 slide back and forth on the inner side of each sliding guide plate 111. Under the downward pressure of the inclined plate 240, the material laminations on the inner side of the sliding guide plate 111 are flattened by the impact of the inclined plate 240 and stick together. Then, through the rotation of the rotary disk 110, they gradually move to the top of the output end conveyor belt 120 and are output by the output end conveyor belt 120. The continuous rotation of the rotary disk 110 realizes the continuous automatic stacking of stator and rotor laminations.
