AI Technical Summary
In the existing technology, during the processing of motor stators, especially in the automated production of flat wire motor stators, the flat wire clamping mechanism often uses a rigid clamping mechanism. This makes it difficult to accurately control the clamping force of the flat wire, resulting in indentations, scratches, and damage to the surface of the flat wire. When the clamping force is too large, it is easy to leave indentations, scratches, or even puncture the insulation layer on the surface of the flat wire, causing the product to be scrapped. When the clamping force is too small, the copper wire cannot be fixed when picking up the wire at the pressing station, making it impossible to remove the spool smoothly, or directly damaging the hair clip during wire picking, affecting the insertion accuracy and processing qualification rate of subsequent stations.
An automatic wire clamping mechanism is adopted, including a clamping unit. The clamping unit includes an unlocking rod, a drive cylinder, an elastic element, a stacked plate group, a limit clamping cylinder, and a support component. The elastic element pushes the stacked plate individual, and the limit clamping cylinder and the stacked plate group work together to achieve flexible clamping, ensuring that the flat wire maintains a stable posture during transportation and avoiding damage to the wire surface.
It effectively avoids deformation or scattering of the spool caused by wire vibration and tray impact, ensuring that the card enters the next station with a consistent posture, improving the pass rate of subsequent processes, reducing the scrap rate of workpieces, and has the versatility of multi-specification production and convenient changeover, shortening changeover downtime and reducing tooling management costs.

Abstract
Description
Technical Field
[0001] This invention relates to the field of motor stator processing and manufacturing technology, specifically to an automatic wire insertion clamping mechanism. Background Technology
[0002] In the automated production process of flat wire motor stators, after the flat wire hair clips are inserted, they need to be transferred via a high-speed chain return line before entering the pressing station. During this transfer, the clamping mechanism needs to reliably fix the inserted hair clips, ensuring they maintain a stable posture and preset arrangement order throughout pallet transport, robotic handling, and station switching. However, existing clamping mechanisms mostly use rigid jaw structures, relying on power sources such as cylinders to drive the jaws to directly clamp the hair clips. Because the flat wire hair clips are rectangular cross-section copper parts with an insulating layer on their surface, the clamping force of the rigid jaws is difficult to control precisely: if the clamping force is too large, it can easily leave indentations, scratches, or even punctures on the surface of the flat wire, causing product scrap; if the clamping force is too small, the copper wire cannot be fixed when removing the wire at the pressing station, resulting in the inability to remove the wire spool smoothly, or directly damaging the hair clip during wire removal. This directly affects the insertion accuracy and processing pass rate of subsequent stations. Summary of the Invention

[0004] This invention proposes an automatic cable clamping mechanism, comprising: a clamping unit, which includes an unlocking rod, a drive cylinder, an elastic element, a stacked plate assembly, a limiting clamping cylinder, and a supporting component, wherein: The drive cylinder is conical or bowl-shaped and coaxially mounted on the unlocking rod, with its small end fixedly assembled with the unlocking rod. The unlocking rod is axially slidably mounted on the support component. The support component, located below the unlocking rod, has a lifting hole coaxially arranged with the unlocking rod for inserting a lifting rod and engaging with the unlocking rod. One end of the elastic element directly or indirectly abuts against the unlocking rod in the telescopic direction, and the other end directly or indirectly abuts against the small end of the drive cylinder in the telescopic direction. The stacked plate assembly includes several stacked plate units, each of which has a slot arranged diagonally. Each stacked plate unit is sequentially engaged with the periphery of the large end of the drive cylinder through its respective slot and is evenly distributed along the circumference of the drive cylinder. The limiting clamping cylinder is coaxially nested outside the drive cylinder and supported by the support component. The inner side of the limiting clamping cylinder has several corresponding slots along its circumference that correspond one-to-one with the stacked plate units. In the initial state of the elastic element, each stacked plate unit is located in its corresponding slot and abuts against the bottom wall of the corresponding slot.
[0005] Preferably, it further includes a first drive component for providing driving force for the axial lifting and lowering of the unlocking rod; the first drive component is arranged at the wiring station and has a lifting rod; the first drive component has a lifting state and a retracted reset state; in the lifting state, the end of the lifting rod extends into the lifting hole opened on the unlocking rod and abuts against the unlocking rod, thereby lifting the unlocking rod to force the drive cylinder to move towards its larger end, and the elastic element enters a compressed state; in the retracted reset state, the lifting rod exits the lifting hole.
[0006] Preferably, a protective insert is provided on the laminated unit, which is nested on the outside of the laminated unit and is used to form a flexible contact with the inserted wire in the clamped state.
[0007] Preferably, the elastic element is a helical spring, and the elastic element is located inside the drive cylinder and sleeved on the unlocking rod.
[0008] Preferably, the elastic element is a rectangular helical spring.
[0009] Preferably, the clamping unit further includes a wire insertion plate, which has multiple wire insertion slots along its circumference. The wire insertion plate is arranged above the limiting clamping cylinder and is connected to the supporting component through an axially retractable guide component. Each wire insertion slot is vertically aligned with and connected to the corresponding slot on the limiting clamping cylinder.
[0010] Preferably, the clamping unit further includes a wire guide plate; the wire guide plate has multiple wire grooves along its circumference, the wire guide plate is disposed between the wire insertion plate and the limiting clamping cylinder, and is fixed to the supporting component by a positioning rod, and the two ends of each wire groove are vertically aligned and connected to each wire insertion groove on the wire insertion plate and each corresponding groove on the limiting clamping cylinder.
[0011] Preferably, the lower end of the power strip is provided with at least two lifting positions arranged circumferentially, and each lifting position is provided with a lifting and positioning component for engaging with the lifting drive component.
[0012] Preferably, the unlocking rod is equipped with an upper linear bearing and a lower linear bearing. The upper linear bearing is fixedly connected to the guide coil, and the lower linear bearing is fixedly connected to the support component. The drive cylinder is located between the upper linear bearing and the lower linear bearing. One end of the elastic element abuts against the lower end of the upper linear bearing, forming an indirect abutment with the unlocking rod.
[0013] Preferably, it further includes a second drive component for providing driving force for the axial lifting and lowering of the connector receptacle; the second drive component is arranged at the connector station, the second drive component has lifting rods, and the number of second drive lifting rods is two; the second drive component has a lifting state and a retracted reset state; in the lifting state, the two lifting rods extend synchronously and abut against the two lifting and positioning components respectively, and lift the connector receptacle; in the retracted reset state, the two lifting rods retract synchronously.
[0014] This invention, through the cooperation of a limiting clamping cylinder and a stacking assembly, provides stable clamping for the wire clips during transport, effectively preventing deformation or scattering of the wire spools caused by wire vibration or tray impact. This ensures the wire clips enter the next workstation with a consistent and accurate posture, significantly improving the pass rate of subsequent processes. Furthermore, this invention abandons the traditional rigid clamping method, employing elastic elements to push the stacking units. This provides sufficient clamping force to meet transport and wire insertion requirements while completely avoiding the risks of flat wire bending and insulation layer scratches, significantly reducing workpiece scrap rates and effectively improving product yield. In addition, when adapting to flat wire stators with different outer diameters, only the limiting clamping cylinder needs to be replaced to change the clamping inner and outer diameters, eliminating the need to replace the entire tooling set. This significantly shortens changeover downtime and reduces tooling management costs while meeting multi-specification production needs. Compared with existing methods, this invention has the following advantages: 1. The radial opening and closing of the stacked units is achieved through the conical surface mating, ensuring a high degree of consistency in clamping force across multiple workstations.
[0015] 2. The elastic reset contact design can effectively avoid damage to the wire surface.
[0016] 3. The limit clamping cylinder can be replaced separately, enabling quick changeover for multiple product specifications and offering strong versatility and changeover advantages. Attached Figure Description

[0018] Reference Figure 1-6The present invention proposes an automatic wire clamping mechanism, comprising: a clamping unit, which includes an unlocking rod 1, a driving cylinder 2, an elastic element 3, a stacked plate group, a limiting clamping cylinder 5, and a supporting component 6.
[0019] like Figure 1 As shown, the drive cylinder 2 is conical or bowl-shaped and coaxially mounted on the unlocking rod 1, with its smaller end fixedly assembled with the unlocking rod 1. The unlocking rod 1 is axially slidably mounted on the support component 6. The support component 6, located below the unlocking rod 1, has a lifting hole coaxially arranged with the unlocking rod 1 for inserting a lifting rod and engaging with the unlocking rod 1. This structural design ensures that the drive cylinder 2 can move synchronously with the axial sliding of the unlocking rod 1.
[0020] One end of the elastic element 3 directly or indirectly abuts against the unlocking rod 1 in the telescopic direction, and the other end directly or indirectly abuts against the small end of the drive cylinder 2 in the telescopic direction. Specifically, the elastic element 3 is a rectangular helical spring, and the elastic element 3 is located inside the drive cylinder 2 and sleeved on the unlocking rod 1. This structural design ensures that the unlocking rod 1 can quickly and automatically reset along with the drive cylinder 2 when the external force disappears.
[0021] like Figure 2 As shown, the lamination group includes several lamination units 4, each lamination unit 4 having a slot 41 arranged diagonally on its side. Each lamination unit 4 is sequentially engaged with the periphery of the large end of the drive cylinder 2 through its respective slot 41, and is evenly distributed along the circumference of the drive cylinder 2. This structure allows the drive cylinder 2 to move axially, and as the insertion depth of the large end of the drive cylinder 2 in the slot 41 changes, it pushes each lamination unit 4 in the lamination group to produce radial displacement.
[0022] like Figure 3 As shown, the limiting clamping cylinder 5 is coaxially nested outside the driving cylinder 2 and supported by the supporting component 6. The inner side of the limiting clamping cylinder 5 has several corresponding grooves 51 along its circumference, each corresponding to one of the stacked individual pieces 4. In the initial state of the elastic element 3, each stacked individual piece 4 is located in its corresponding groove 51 and abuts against the bottom wall of the corresponding groove 51. This structure design allows each stacked individual piece 4 to undergo radial displacement relative to the limiting clamping cylinder 5 when the driving cylinder 2 undergoes axial displacement relative to the limiting clamping cylinder 5, changing the degree of contact between each stacked individual piece 4 and the bottom wall of the corresponding groove 51, thereby achieving clamping or releasing action. The specific clamping principle is as follows: In the initial state, the elastic element 3 is in a naturally extended state, and the drive cylinder 2 is located at a lower position under the action of the elastic element 3. Each stacked unit 4 is in contact with the bottom wall of the corresponding groove 51, and the corresponding groove 51 is in a closed state at this time, so the hairpin cannot pass through the limiting clamping cylinder 5. When it is necessary to insert the wire, the lifting rod of the external lifting drive component (such as the first drive component 9) is inserted into the lifting hole on the support component 6 from below, abutting against the lower end of the unlocking rod 1 and lifting the unlocking rod 1 upward. When the unlocking rod 1 moves upward, it drives the drive cylinder 2, which is fixedly mounted with it, to move synchronously towards the larger end. Since one end of the elastic element 3 abuts against the unlocking rod 1 and the other end abuts against the smaller end of the drive cylinder 2, the upward movement of the drive cylinder 2 will compress the elastic element 3 to store energy. As the drive cylinder 2 moves towards the larger opening, its conical outer wall pushes each stacked unit 4 to contract inward along the inclined direction of the slot 41, causing each stacked unit 4 to gradually separate from the bottom wall of the corresponding slot 51. A channel is formed between each stacked unit 4 and the bottom wall of the corresponding slot 51, allowing the hairpin to pass through. At this time, the hairpin naturally falls into the channel under the action of gravity and passes through the limiting clamping cylinder 5 to reach the preset clamping position. When the hairpin is in place, the lifting drive component retracts and resets, the lifting rod exits the lifting hole, the external force acting on the unlocking rod 1 disappears, the compressed elastic element 3 automatically extends and resets, pushing the unlocking rod 1 and the drive cylinder 2 back towards the smaller opening. Each stacked unit 4, driven by the drive cylinder 2, resets outward along the inclined direction of the slot 41 and re-abuts against the bottom wall of the corresponding slot 51. The corresponding slot 51 re-enters the closed state, thereby firmly clamping the hairpin located in the channel and completing the wire insertion clamping operation.
[0023] The specific structural design and layout of the first drive component 9 are as follows: The first drive component 9 is arranged at the wiring station and has a lifting rod. The first drive component 9 has a lifting state and a retracted reset state; in the lifting state, the end of the lifting rod extends into the lifting hole opened on the unlocking rod 1 and abuts against the unlocking rod 1, thereby lifting the unlocking rod 1 to force the drive cylinder 2 to move towards its larger end, and the elastic element 3 enters a compressed state; in the retracted reset state, the lifting rod exits the lifting hole.
[0024] As a further preferred option, in this embodiment, the first driving component 9 can be a linear driving element such as a cylinder, hydraulic cylinder or electric push rod, with cylinder driving being preferred, which has the advantages of fast response speed and high control accuracy.
[0025] As a further preferred embodiment, a protective insert 42 is provided on the laminated monomer 4. The protective insert 42 is made of a wear-resistant polymer material such as POM (polyoxymethylene). The protective insert 42 is nested on the outside of the laminated monomer 4 to form a flexible contact with the inserted wire in the clamped state. This structural design effectively avoids scratches or indentations on the wire surface and improves clamping stability and reliability by increasing the contact area and the coefficient of friction.
[0026] As a further preferred embodiment, the clamping unit further includes a wire insertion tray 7 and a wire guide tray 8. The wire insertion tray 7 has multiple wire insertion slots along its circumference. The wire insertion tray 7 is positioned above the limiting clamping cylinder 5 and connected to the supporting component 6 via an axially retractable guide assembly 71. Each wire insertion slot is vertically aligned with its corresponding slot 51 on the limiting clamping cylinder 5. The wire guide tray 8 has multiple wire guide slots along its circumference. The wire guide tray 8 is positioned between the wire insertion tray 7 and the limiting clamping cylinder 5 and is fixed to the supporting component 6 via a positioning rod 81. The two ends of each wire guide slot are vertically aligned with their respective wire insertion slots on the wire insertion tray 7 and their corresponding slots 51 on the limiting clamping cylinder 5. The insertion tray 7 and the guide tray 8 together form a continuous guide channel from the insertion inlet to the clamping station. The insertion tray 7 performs initial posture correction and circumferential positioning of the inserted hair clips through each insertion slot, ensuring that each hair clip falls accurately into the corresponding vertical path. The guide tray 8 provides secondary guidance between the insertion tray 7 and the limiting clamping cylinder 5 through each guide slot, further constraining the insertion direction and tilt angle of the hair clips, preventing the hair clips from deviating, twisting or getting stuck during the falling process. Thus, while achieving accurate and smooth insertion, it effectively avoids insertion failure or damage to the stacked unit 4 and the protective insert 42 due to path deviation.
[0027] As a further priority, in this embodiment, the lower end of the connector 7 is provided with at least two circumferentially spaced lifting positions, and each lifting position is provided with a lifting positioning component 72 for abutting and cooperating with the lifting drive component. Compared with the traditional single-sided lifting method, this structural design, by providing at least two circumferentially spaced lifting positions at the lower end of the connector 7 and configuring a lifting positioning component 72 at each lifting position, enables the lifting drive component (such as the second drive component 10) to achieve multi-point synchronous force when acting on the connector 7. This ensures that the connector 7 is subjected to balanced force and moves smoothly during the lifting process, effectively avoiding malfunctions such as jamming and stalling caused by unilateral load. At the same time, since multi-point synchronous lifting eliminates the tilting tendency of the connector 7 during lifting, the requirements for the machining accuracy and fitting clearance of related components can be appropriately relaxed, effectively reducing the manufacturing difficulty and production cost while ensuring the positioning accuracy of the connector 7.
[0028] The specific structural design and arrangement of the second drive component 10 used to drive the lifting and lowering of the cable tray 7 are as follows; The second drive component 10 is arranged at the wiring station. The second drive component 10 has two lifting rods. The second drive component 10 has a lifting state and a retracted reset state: in the lifting state, the two lifting rods extend synchronously and abut against the two lifting and positioning components 72 respectively, lifting the wiring tray 7; in the retracted reset state, the two lifting rods retract synchronously. Through the synchronous extension and retraction movement of the two lifting rods, the smooth lifting and lowering drive of the wiring tray 7 is realized. Compared with the single-point drive method, the synchronous action of the double lifting rods can apply force at two spaced lifting positions of the wiring tray 7 at the same time, effectively ensuring that the wiring tray 7 always maintains a horizontal posture during the lifting and lowering process, avoiding the wiring tray 7 from tilting or jamming due to uneven force on one side, thereby ensuring that the vertical alignment accuracy between each wiring slot and the lower wire slot and the corresponding slot 51 is not compromised.
[0029] Reference Figure 7 In practice, a mounting base 01 is provided at the insertion station, and a rotary drive assembly 03 for driving the clamping unit to rotate is provided on the mounting base 01. In this embodiment, both the first drive component 9 and the second drive component 10 are mounted on the mounting base. The clamping unit is moved to the insertion station via a turntable tray 02 set on the conveyor line to perform the insertion operation.
[0030] As a further preferred embodiment, this embodiment configures an upper linear bearing 11 and a lower linear bearing 12 on the unlocking rod 1. The upper linear bearing 11 is fixedly connected to the guide plate 8, and the lower linear bearing 12 is fixedly connected to the support component 6. The drive cylinder 2 is located between the upper linear bearing 11 and the lower linear bearing 12. One end of the elastic element 3 abuts against the lower end of the upper linear bearing 11, forming an indirect abutment with the unlocking rod 1. This structural design achieves dual guiding support for the axial movement of the unlocking rod 1, ensuring high coaxiality and smooth movement of the drive cylinder 2 during the pushing process of the lifting rod and the resetting process of the elastic element 3. It can effectively reduce jamming and wear caused by off-center load, and ensure the consistency of the movement of each stacked unit 4 of the stacked assembly, clamping accuracy, and overall service life of the mechanism.
[0031] As can be seen from the above, this invention, through the cooperation of the limiting clamping cylinder 5 and the lamination assembly, forms a stable clamping of the hairpin during the transfer process. This effectively avoids deformation or scattering of the wire spool caused by line vibration, tray impact, etc., ensuring that the hairpin enters the next workstation with a consistent posture, thereby significantly improving the pass rate of subsequent processes. Simultaneously, this application abandons the traditional rigid clamping method, using an elastic element 3 to push the lamination unit 4, combined with a POM protective insert 42 nested on the outside of the lamination unit 4, forming a flexible clamping with uniform surface contact for the hairpin. This provides sufficient clamping force to meet the transfer and insertion requirements, while completely avoiding the risk of flat wire bending and insulation layer scratches and damage, significantly reducing the workpiece scrap rate and effectively improving the product yield. Furthermore, this application has strong versatility and ease of changeover. When it is necessary to adapt to flat wire stators with different outer diameter specifications, only the limiting clamping cylinder 5 needs to be replaced to change the clamping inner and outer diameters, without the need to replace the entire tooling set. This significantly shortens changeover downtime and reduces tooling management costs while meeting the needs of multi-specification production. Compared with existing technologies, it has the following advantages: 1. The radial opening and closing of the stacked units is achieved through the conical surface mating, ensuring a high degree of consistency in clamping force across multiple workstations.
[0032] 2. The elastic reset contact design can effectively avoid damage to the wire surface.
[0033] 3. The limit clamping cylinder can be replaced separately, enabling quick changeover for multiple product specifications and offering strong versatility and changeover advantages.
[0034] In summary, this invention combines the advantages of high-consistency clamping, zero-damage protection, and strong versatility in changeover, effectively solving the prominent problems of poor clamping reliability, high workpiece damage rate, and low changeover efficiency in the prior art, and has good market application prospects.
[0035] Furthermore, in this embodiment, the transfer tray for operating the clamping unit is provided with a positioning groove adapted to the clamping unit, and the positioning groove is stepped hole-shaped; the entire clamping unit is detachably installed on the transfer tray through positioning engagement with the positioning groove. This structural design enables rapid changeover between clamping units of different specifications, while ensuring the repeatability of the clamping unit's positioning accuracy at the wire insertion station after changeover. It can be put into production directly without recalibration, effectively shortening downtime and improving changeover efficiency in multi-variety flat wire production scenarios.
[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
