Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing equipment technology, specifically to a dual-station variable frequency motor wire clamping and take-up mechanism. Background Technology

[0002] In the production process of a dual-station variable frequency motor stator, after the dual-station winding machine completes the winding process, the enameled wires from both stations need to be cut separately, and the waste wires cut off need to be collected. Existing technologies, such as the dual-station external winding machine for stators proposed in Chinese patent CN109660091A, provide both winding and cutting functions, but lack waste wire collection. This leads to waste wires being scattered in the equipment gaps or tangled on the stator surface after cutting, resulting in low waste wire collection success rates and potential wear on the motor stator surface. Manual cleaning is required, affecting production continuity and workshop cleanliness. Furthermore, the connection between winding and cutting relies on the movement and alignment of the winding nozzle and the cutting assembly, rather than overall transport. The movement of the cutting assembly adapts to the stator position, processing only one station at a time. Dual-station cutting requires resetting and repositioning, increasing operational complexity. Moreover, there is no rigid linkage between the wire clamping and cutting; the wire end may shift due to vibration during cutting, resulting in uneven cuts or excessively long residues, leading to insufficient cutting accuracy.

[0003] Therefore, there is an urgent need for a transfer and auxiliary processing mechanism specifically designed for the stator of a dual-station variable frequency motor, which can realize the integrated linkage of wire cutting and waste wire collection, thereby improving production efficiency and stability. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-station variable frequency motor wire clamping and take-up mechanism. Through the vertical coordination of the pneumatic gripper and the wire cutting device driven by the cylinder, a relatively complete and automated waste wire processing process is formed, which improves the wire cutting accuracy and collects waste wire at the same time, thereby improving the production efficiency and cleanliness of the workshop.

[0005] Another objective of this invention is to use a rotary disk to drive the overall transfer design of the components, so that the dual-station motor stator with completed winding can be transferred to the corresponding wire cutting station in one go for wire cutting, without the need for repeated movement and adjustment of the wire cutting components. This solves the problem that the existing dual-station wire cutting requires repeated reset-positioning processes, which are cumbersome and time-consuming.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dual-station variable frequency motor wire clamping and take-up mechanism, comprising at least two components. Each component is fixed within a turntable and holds an uncut motor stator. Each component has through-hole slots along the extension direction of the main and auxiliary stations of the motor stator. A through-hole corresponding to the position of the through-hole slot is provided on the worktable surface. A cylinder is located below the through-hole, and a pneumatic gripper is mounted on the cylinder. The correspondence between the through-hole slot and the through-hole provides a precise movement channel for the pneumatic gripper, ensuring that the gripper can rise without interference to the main and auxiliary stations of the motor stator to clamp the wire, providing a foundation for subsequent wire cutting processes. Simultaneously, the through-hole slots and through-holes provide a certain amount of space for the waste wire during the repositioning process of the pneumatic gripper clamping the waste wire, allowing the waste wire to be collected below the worktable surface through the through-hole slots and through-holes instead of scattering on the worktable surface.

[0007] Preferably, the assembly consists of three components, positioned as a first, second, and third workstation. A turntable is rotatably mounted above the worktable and driven by a drive shaft to switch between workstations. Each of the three workstations can handle different processes, with automatic switching via the turntable rotation creating a continuous workflow. This significantly reduces process connection time. The dual-station motor stator is transferred to the corresponding wire-cutting workstation in a single operation, eliminating the need for repeated movement and adjustment of the wire-cutting components and removing the wire-cutting device reset-positioning process, thus improving work efficiency.

[0008] Preferably, the first station is a workpiece switching station, while the second and third stations are both wire cutting stations. This achieves specialized division of labor in the process, forming a highly efficient assembly line operation, significantly shortening the processing cycle of a single workpiece, and significantly improving the efficiency of batch production.

[0009] Preferably, a wire-cutting device is installed above the second and third workstations, working vertically in coordination with the cylinders below to cut the wire. The lower cylinder drives the gripper to quickly clamp the wire end, providing stable support, while the upper wire-cutting device performs the cutting action simultaneously. The independent vertical coordination system of the two workstations allows for parallel operation. The vertical coordination design allows the wire-cutting device and the cylinder to be arranged in layers, avoiding horizontal structural interference, saving workbench space, and providing sufficient movement clearance for the rotation and switching of the turntable-driven components, ensuring smooth process flow.

[0010] Preferably, the first through hole on the worktable is located below the second station, corresponding to the through-hole slot extending in the direction of the motor stator auxiliary station, and the second through hole is located below the third station, corresponding to the through-hole slot extending in the direction of the motor stator main station. This achieves precise matching of station functions, allowing the pneumatic gripper of each wire cutting station to accurately align with the wire end of the corresponding station through a dedicated channel, ensuring that the wire clamping and cutting actions are fully adapted to the extension directions of the main and auxiliary stations, and reducing the risk of misalignment.

[0011] Preferably, the components are circular and centrally symmetrically distributed, with semi-circular arc grooves for the through holes. This centrally symmetrical structure ensures the turntable maintains its center of gravity balance during rotation, preventing additional vibration or wobbling caused by center of gravity shift, reducing the impact on the positioning accuracy of the motor stator, ensuring stability at each workstation during processing, and minimizing wire-cutting errors caused by equipment vibration. Simultaneously, the centrally symmetrical distribution is highly compatible with the turntable's rotational characteristics, ensuring that the relative position of each component with the worktable's through holes, wire-cutting devices, etc., remains consistent when switching to different workstations. This guarantees uniformity of processing conditions at each workstation, improves product quality uniformity, and facilitates equipment debugging and maintenance.

[0012] Preferably, the component has a through slot that mates with the outer contour of the motor stator. A first positioning block and a second positioning block are respectively located below the main and auxiliary workstations of the motor stator. The through slot, along with the first and second positioning blocks, form a three-dimensional positioning system in the radial, circumferential, and axial directions. This ensures the precise and stable positioning of the motor stator within the component, providing a reliable reference for subsequent pneumatic clamping and shearing of the wire, effectively avoiding processing errors caused by stator displacement and improving product quality consistency. Simultaneously, this positioning method adapts to the structural differences between the two workstations, allowing stable support for processing at both the main and auxiliary workstations, ensuring the accuracy of parallel operation of both workstations.

[0013] Preferably, the pneumatic gripper is connected to the top of the cylinder body via fasteners, the cylinder body is fixed to the cylinder bracket, and the cylinder bracket is fixed to the ground via a horizontal support plate at the bottom. This rigid connection ensures accuracy during operation, and the gripping force and reaction force are transmitted to the ground layer by layer, reducing trajectory deviation caused by vibration and providing a foundation for precise line clamping.

[0014] Preferably, the width of the pneumatic gripper matches the diameter of the through-hole groove. Driven by a cylinder, the pneumatic gripper rises, passes through the through-hole and the through-hole groove, and clamps the wire end. This ensures that the gripper does not interfere with the groove or through-hole when it rises, accurately aligns with the wire end, avoids jamming or misalignment, and the tightly fitted structure allows the gripper to stably clamp the wire end, providing reliable rigid support for wire cutting and improving cutting accuracy and stability.

[0015] Preferably, after the pneumatic gripper cuts off the wire end, it causes the waste wire to reset, releasing it so that the waste wire falls into the collection box below. The process of the gripper resetting the waste wire avoids waste wire remaining in the workstation or equipment gaps, preventing interference with subsequent operations or equipment jamming. It also keeps the working environment clean, reduces safety hazards, and achieves automatic waste wire recycling without manual cleaning, reducing process interruptions and improving production continuity.

[0016] The dual-station variable frequency motor wire clamping and take-up mechanism invented in this utility model, through the cooperation of through holes set on the worktable and the component, enables the cylinder-driven gripper located below the stator of the dual-station variable frequency motor to work in concert with the wire-cutting mechanism located above, automatically completing the wire-cutting work on the stator of the dual-station motor under the drive of the turntable. This entire linkage mechanism is not a simple combination of existing technologies, but achieves new functions and effects through ingenious structural design and workflow planning. The beneficial effects of this solution are:

[0017] The three components are evenly distributed within the turntable, allowing for flexible switching of work positions and further improving the equipment's flexibility and adaptability.

[0018] By using a cylinder gripper and a wire cutting mechanism in vertical coordination through a through-hole, waste wires are precisely and directionally transferred, solving the problem of scattered cut wire ends requiring manual cleaning in traditional equipment. The entire process requires no manual intervention and is in line with the trend of automated production.

[0019] This technology improves the automation level of wire winding, clamping, and waste wire handling in motor production, reducing manual intervention and labor intensity, while also increasing production efficiency and product quality stability. Precise wire clamping and cutting operations reduce waste of enameled wire and product defect rates, offering significant advantages compared to traditional manual operations or equipment with low levels of automation.

[0020] By using a turntable with three components, dual-station alternating operation is achieved, breaking the traditional single-station or fixed-station wire winding and clamping mode. It can significantly improve work efficiency without increasing the equipment footprint, allowing multiple motor stators to be operated at different stages simultaneously on the same set of equipment, thus improving equipment utilization.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are merely partial embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figure 1 As shown, a worktable 2 is located at the top of the frame 1, and two cylinders 5 are located at the bottom. A turntable 3 is located above the worktable 2. Three components 4 are evenly arranged in a centrally symmetrical structure within the turntable 3. A dual-station variable frequency motor stator 41 with wound wire but not yet cut is placed on the components 4. The initial positions of the three components 4 are the first station 4a, the second station 4b, and the third station 4c, respectively. A circular shaft hole is provided in the center of the turntable 3, which connects to a drive shaft (not shown in the figure). The drive shaft drives the turntable 3 to rotate, thereby driving the components 4 to rotate, realizing the automatic switching of the motor stator 41 between the first station 4a, the second station 4b, and the third station 4c.

[0029] The first station 4a is used to switch between the wire to be cut and the dual-station variable frequency motor stator 41 with the cut wire, or a dual-station motor stator winding device can be directly installed above the first station 4a. A wire-cutting device is installed above the second station 4b and the third station 4c respectively to cut the wire at each of the two stations of the dual-station variable frequency motor stator 41. The two stations of the dual-station stator are cut independently by 4b and 4c. Each wire-cutting station can be precisely set for parameters such as wire diameter and position for the corresponding stator station, avoiding potential interference when processing two stations simultaneously, resulting in more precise wire cutting. When the turntable rotates to switch stations, the three stations can perform their respective processes simultaneously, rather than in a single-station serial mode. This achieves a parallel process where other stations operate synchronously while one station is operating, eliminating single-station waiting time and significantly improving productivity per unit time. Automatic process switching is achieved by driving the turntable to rotate via a drive shaft, eliminating the need for manual handling or adjustment of workpiece positions. This fundamentally reduces manual intervention, lowers reliance on human labor, and reduces labor costs. It also minimizes process interruptions caused by inconsistent manual operation rhythms, ensuring production continuity. The turntable and its components employ a centrally symmetrical design, ensuring that the center of gravity always coincides with the center of the drive shaft during rotation. This reduces vibration or swaying caused by center of gravity shift, thus minimizing errors during processing.

[0030] like Figure 2 and Figure 3 As shown, a through slot 42 is provided in the center of the small disc 4, which mates with the outer contour of the motor stator 41. The contour dimensions of the through slot 42 are precisely matched with the outer contour of the motor stator 41, enabling accurate installation and rigid radial positioning of the motor stator 41. During installation, the outer contour of the stator fits tightly against the inner wall of the through slot, completely restricting the stator's swaying or displacement in the radial horizontal direction. This ensures that the stator's position is fixed during the wire cutting process. This positioning accuracy directly determines the accuracy of subsequent processes, such as the wire cutting device's cutting position of the main and auxiliary workstation wires, avoiding quality problems caused by inconsistent wire cutting lengths due to stator offset, and improving product consistency.

[0031] In the outer periphery of the through slot 41, through slots 43 are respectively provided along the outward extension directions of the main station 41a and auxiliary station 41b of the motor stator. The opening direction of the through slots 43 is consistent with the extension paths of the main and auxiliary stations, but the extension paths of the main and auxiliary stations are not on the same straight line, forming a certain angle. The design of the through slots 43 is adapted to the extension paths of the main station 41a and auxiliary station 41b, providing a precise working space for the gripper device and ensuring the feasibility of the wire cutting action. The pneumatic gripper 51 needs to rise from below to the position of the enameled wire and grab the wire end. The depth and width of the through slot 43 can accommodate the movement trajectory of the gripper, avoiding collision and interference between the pneumatic gripper 51 and the surface of the component 4 or the main body of the motor stator 41, ensuring that the gripper can smoothly reach the target position.

[0032] Below the main station 41a and auxiliary station 41b of the motor stator, a first positioning block 44 and a second positioning block 45 are respectively provided. Both positioning blocks have an arc structure adapted to the bottom of the motor stator 41. The arrangement direction of the first positioning block 44 and the second positioning block 45 is perpendicular to the extension path of the main and auxiliary stations of the motor stator, and their arc contours precisely match the outer circular contour of the bottom of the motor stator, achieving a close-fitting positioning of the stator bottom and avoiding inaccurate wire cutting positioning due to positional offset of the motor stator 41. The two positioning blocks are fastened to the assembly 4 with bolts, forming independent support and limiting for the main and auxiliary stations of the motor stator 41, ensuring the circumferential and axial positional accuracy of the motor stator on the assembly 4. The through slot 42, together with the first positioning block 44 and the second positioning block 45, forms a close-fitting contact with the motor stator 41, thereby restricting the rotation of the motor stator 41 and ensuring the accurate angular position of the main and auxiliary stations. The through-hole groove 43 provides an insertion channel for the tool to cut the wire in the subsequent process, ensuring that the tool can accurately act on the wire end at the target position of the main and auxiliary workstations without having to avoid the small disc body, thus improving the convenience of processing.

[0033] Component 4 is the core load-bearing and positioning component in the wire shearing process of the stator 41 of the dual-station variable frequency motor. Through the synergistic effect of the through slot 42 and the positioning block, it achieves multi-dimensional precise positioning of the motor stator, ensuring processing accuracy, providing stable support and structural protection for the main and auxiliary stations of the stator, adapting to the wire shearing process, providing space and guidance for tool operation, and directly ensuring the stability of production efficiency and product quality.

[0034] like Figure 4 As shown, the worktable 2 has a first through hole 21 and a second through hole 22. The first through hole 21 and the second through hole 22 are mirror images of each other with the center of the worktable as the symmetrical point. The diameter of the two through holes is slightly larger than the maximum outer diameter of the pneumatic gripper 51, ensuring that the pneumatic gripper 51 can pass through without interference and can pass through the radial constraint of the hole wall, ensuring that the pneumatic gripper 51 moves along the preset axis and avoids deviation. The position of the first through hole 21 corresponds to the through hole slot extending in the direction of the motor stator auxiliary station 41b of the component 4 on the second station 4b, and the position of the second through hole 22 corresponds to the through hole slot extending in the direction of the motor stator main station 41a of the component 4 on the third station 4c. Eight small round through holes are evenly distributed on the outer periphery of the through holes. A cylinder 5 is respectively provided at the bottom of the first through hole 21 and the second through hole 22. The pneumatic gripper 51 rises under the drive of the cylinder 5 and clamps the wire end to be cut on the motor stator 41 through the first through hole 21, the second through hole 22 and the through hole groove 43, providing rigid support for the wire cutting mechanism to perform the wire cutting process.

[0035] The through-hole design, combined with the path guidance of the through-hole groove 43, ensures unobstructed movement of the gripper from the bottom to the wire end, completely eliminating the risk of collision with the worktable and small disc. The mirror-symmetrical through-hole layout corresponds one-to-one with the main and auxiliary stations of the dual-station motor stator, allowing the pneumatic gripper 51 to independently act on the wire ends of both stations without interference, adapting to the needs of parallel wire cutting in dual-station operation. The mirror-symmetrical layout ensures balanced force on the worktable, with symmetrically distributed reaction forces during pneumatic gripper 51 operation, reducing deformation of the worktable due to excessive localized force and extending equipment lifespan. The gap design between the through-hole and the pneumatic gripper 51 provides a small tolerance margin, such as for machining errors and slight vibrations, preventing jamming due to excessive tightness and improving equipment reliability. The through-hole design on the worktable 2 achieves precise docking of the worktable, pneumatic clamping device and components through the three-stage cooperation of pneumatic gripper 51-through-through-slot 43: pneumatic gripper 51 passes through the through-hole from below the worktable 2 and then reaches the main and auxiliary station of the motor stator through the through-hole slot 43, forming a closed loop of linear motion and path guidance, ensuring that the clamping action and the working range of the wire cutting device are fully matched, providing stable preconditions for the wire cutting process.

[0036] like Figure 5 As shown, AA is a cross-sectional view of cylinder 5. Cylinder 5 is equipped with a pneumatic gripper 51, which is bolted to the top of cylinder body 52. ​​It rises or falls under the drive of cylinder body 52. ​​Cylinder body 52 is fixed on cylinder frame 53. Cylinder frame 53 is fixed to the ground by a flange or bolt assembly through a horizontal support plate 54 at the bottom.

[0037] The rigid connection between the pneumatic gripper 51 and the cylinder 52 ensures that their movement trajectories are completely synchronized. When the cylinder 52 drives the gripper to rise or fall, the pneumatic gripper 51 will not experience relative displacement or wobbling due to a loose connection, ensuring that it accurately passes through the through hole and slot on the worktable and aligns with the wire end, directly improving clamping and positioning accuracy. After the gripper 51 rises and clamps the wire end under the drive of the cylinder 5, the clearance fit between the through hole and the gripper forms a hidden guide, keeping the gripper's clamping posture stable. At the same time, the driving force of the cylinder is transmitted to the gripper through the rigid structure, ensuring that the wire end is rigidly clamped. When the wire cutting mechanism is operating, the wire end will not wobble or shift due to force, avoiding problems such as wire cutting length deviation and excessively long wire ends, significantly improving wire cutting accuracy.

[0038] Bolted connections enable modular replacement. When the gripper 51 wears down due to long-term use, such as when the gripper is deformed or the clamping force decreases, it can be quickly disassembled and replaced without replacing the entire cylinder, thus reducing maintenance costs and downtime. At the same time, it is convenient to replace grippers 51 of different specifications according to the wire end size of the motor stator 41, improving the equipment's adaptability to different types of workpieces.

[0039] The cylinder frame 53 is fixed to the bottom horizontal support plate via flanges or bolt assemblies, and then connected to the ground. This multi-stage fixing method transmits the vibration generated by pneumatic drive and the reaction force of gripping operations to the ground, preventing the overall equipment from shaking. Especially when two cylinders are driven synchronously for simultaneous dual-station operation, the rigidity of the frame balances the forces on both sides, ensuring the stable operation of the worktable, components, and other related parts. The horizontal support plate 54 increases the contact area between the frame and the ground, dispersing the pressure per unit area and preventing the equipment from "settling" or shifting due to long-term load or vibration. For automated production lines in mass production, this stable foundation support is a key prerequisite for ensuring process consistency (such as the gripper 51 rising to the same height each time).

[0040] The gripper 51, as the end-acting component of cylinder 5, adopts an integrated design: its main body is rigidly connected to the top of the cylinder piston rod via bolts. The gripper body contains a small drive mechanism, such as a miniature spring linkage assembly, which can be linked with the lifting and lowering action of cylinder 52. When cylinder 52 drives gripper 51 to the top, the gripper simultaneously completes the "opening → closing" action, switching from the open state to the clamping state. When cylinder 52 drives gripper 51 to descend and reset, the gripper simultaneously performs the "closing → opening" action, releasing the clamped waste wire. The opening and closing stroke of gripper 51 can be finely adjusted by adjusting the limit block of the built-in mechanism, typically within a range of 2-5mm, to accommodate wire ends of different diameters, such as 0.5-2mm enameled wire. The clamping action is completed during the gripper's upward movement, achieving rigid fixation the moment it reaches the position of the wire end to be cut. This avoids wire end displacement caused by "reaching the position before clamping," such as wobbling due to inertia, ensuring that the wire end is in an absolutely stable state when the wire cutter contacts it, significantly reducing cutting errors.

[0041] The integrated design of the gripper 51 and the cylinder reduces intermediate transmission components, making the overall structure more compact. This is especially suitable for installation in limited spaces under the worktable, while also reducing cumulative errors caused by multiple component connections and improving long-term operational stability. This design, through coordinated actions, adjustable force control, and structural integration, perfectly meets the high-precision and high-efficiency requirements of the motor stator wire cutting process.

[0042] The working process of this utility model is as follows:

[0043] The dual-station variable frequency motor stator 41 is embedded in the through slot 42 of the component 4, and together with the first positioning block 44 and the second positioning block 45, it achieves precise radial, circumferential, and axial positioning. The turntable 3 drives the component 4 to rotate, and transports the motor stator 41 to the second station 4b and the third station 4c for wire cutting. At the same time, the first station 4a completes the feeding of new stators or the removal of stators with cut wires. The three stations operate in parallel.

[0044] When the motor stator 41, to be cut, rotates to the second station 4b and the third station 4c, the cylinder 5 below the worktable 2 drives the pneumatic gripper 51 to rise, passing through the through hole and through slot 43 in sequence, clamping the wire end to be cut on the motor stator 41, providing rigid support for wire cutting. The wire cutting mechanism cuts the clamped wire end. After the wire cutting is completed, the gripper 51 descends and resets under the drive of the cylinder. The gripper 51 is released, and the waste wire falls into the collection box (not shown in the figure) set below the gripper 51. The turntable 3 rotates to switch stations and enters the next round of operation.
