Description

Technical Field

[0001] This invention relates to the field of motor winding technology, and more specifically, to a multi-coil detection and feeding module and a winding machine. Background Technology

[0002] Currently, the production of multi-connected coils (i.e., multiple coils wound in series at once) usually requires manual intervention or is carried out in steps during the unloading, inspection, and unloading processes. Traditional equipment often requires removing the formed multi-connected coils from the winding mold during unloading, then transferring them to the inspection station for inspection, and finally collecting them. This method involves scattered processes, low automation, low production efficiency, and is prone to damage to the coils (especially the enameled wires at both ends) during the transfer process, affecting the product qualification rate. Therefore, there is an urgent need for a multi-connected coil inspection and unloading module and winding machine that can integrate automatic unloading and automatic inspection functions. Summary of the Invention

The winding mold includes a base plate fixedly connected to the movable end of the mold locking sub-shaft and a mold seat slidably connected to the base plate longitudinally. The first cylinder is used to push and adjust the height position of the mold seat. The mold seat is laterally slidably provided with a plurality of longitudinally arranged winding plates and a plurality of elastic reset members corresponding one-to-one to the position reset of the winding plates. The end of the winding plate opposite to the mold seat is provided with a winding seat. The mold seat is provided with an opening for the movable end of the second cylinder to extend into. The movable end of the second cylinder is provided with a lifting head for laterally ejecting the winding plate to be wound separately. The base plate is also provided with a reserved wire winding post for reserved wire between the inlet nozzle and the outlet coil. The reserved wire winding post is located between the inlet nozzle and the mold base. The reserved wire winding post has a first state that is higher than the winding plane of the mold base and a second state that is lower than or equal to the winding plane. When the winding plate to be wound is lifted, the reserved wire winding post is triggered to enter the first state. When the winding plate currently being wound is reset, the reserved wire winding post is triggered to enter the second state.

[0007] The multi-wire winding machine of the present invention includes a base plate fixedly connected to a vertical plate, and a hinge seat mounted on the vertical plate; the reserved winding post includes an inverted V-shaped support rod hinged to the hinge seat, a winding post being provided on the upper surface of the end of the support rod away from the hinge seat, and a protruding edge being provided on one side of the support rod located at the winding post for triggering the switching between the first state and the second state; the middle part of the V-shape of the support rod is connected to the vertical plate by a return spring.

[0008] The multi-wire winding machine of the present invention includes an opening on the mold base for multiple winding plates to extend out, a winding stop bar on the edge of the opening, and a winding plane on the side of the winding stop bar facing away from the base plate; the mold base also includes an elongated stepped position for hiding the reserved winding post, the winding stop bar being located between the opening and the stepped position, and the length direction of the stepped position being consistent with the sliding direction of the mold base.

[0009] The multi-wire winding machine of the present invention includes a winding station on the mold base, wherein the winding plate to be wound is pushed out separately by the lifting head after reaching the winding station; the winding column is not directly opposite the winding station.

[0010] The multi-wire winding machine of the present invention includes a first guide block on the side of the winding plate, a first guide groove on the mold base that cooperates with the first guide block, and the first guide groove communicating with the step position; the convex edge is directly opposite the winding station, and the first state and the second state are switched by the first guide block of the winding plate to be wound.

[0013] The multi-wire winding machine of the present invention includes mounting grooves for mounting the elastic reset member on both the left side plate and the right side plate, the mounting grooves being connected to the limiting grooves; the elastic reset member is fixed on the limiting block.

[0014] The beneficial effects of this invention are as follows: 1. Integrated Functions and Continuous Processes: This module integrates the material feeding action with electrical testing functions. While the winding spindle (driving the winding module) retracts to complete the material feeding, the testing and feeding mold can move to clamp the lead wire of the coil and perform testing, realizing the synchronization and continuity of material feeding and testing, significantly shortening the production cycle.

[0015] 2. Non-destructive feeding and stable clamping: By setting up a retractable winding seat and a matching extrusion seat, the extrusion seat of the inspection and feeding die can smoothly press the winding seat back under the push of the transverse cylinder, so that the formed multi-connected coil can be smoothly separated from the winding die, avoiding forced pulling; at the same time, the two inspection clamps can accurately and firmly clamp the enameled wires at both ends of the multi-connected coil, providing a stable foundation for subsequent inspection and feeding operations and preventing wire damage.

[0016] 3. High-efficiency separation and directional transfer: Through the cooperation of the movable fork and its fork teeth with the notch groove on the winding die, the fork teeth of the movable fork can be accurately inserted into the gap between the coils of the multi-connected coils under the drive of the movable fork cylinder. When the lateral movement unit drives the entire lateral movement bracket to move laterally, the multi-connected coils can be efficiently peeled off from the winding die area and transferred to the discharge position. The whole process is automatic, fast and does not interfere with the coil arrangement.

[0017] 4. Compact structure and reliable operation: By setting up a transverse support, a reset unit and a transverse unit, and cooperating with the transverse cylinder of the winding spindle, the precise and coordinated movement of the detection and unloading mold in multiple directions is realized, ensuring the continuity and reliability of a series of actions such as unloading, clamping, detection, separation and discharge. The overall structure is compact and suitable for automated production lines. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0020] like Figures 1-6As shown, the multi-wire winding machine of the present invention, in a preferred embodiment, includes a frame, a winding spindle 1, a die locking sub-shaft 2, and a winding die 3; the winding spindle 1 and the die locking sub-shaft 2 are arranged opposite to each other, and the winding die 3 is fixed by the die locking sub-shaft 2. The winding spindle 1 includes a winding module 11 and a transverse cylinder 12, which drives the winding module 11 to move laterally along a first direction (e.g., the X-axis direction) to perform winding or unwinding.

[0021] The multi-wire winding machine also includes a detection and unloading die 8 located on one side of the winding spindle 1. The detection and unloading die 8 is laterally slidably connected to a transverse support 80 via a slider, and can move along a second direction (e.g., the Y-axis direction, perpendicular to the X-axis direction). The transverse support 80 is driven by a transverse unit 81 (such as a motor-driven lead screw slide), enabling the entire detection and unloading die 8 to move a large stroke along the Y-axis direction. A reset unit (such as a tension spring) is connected between the detection and unloading die 8 and the fixed part of the transverse support 80, providing a reset tendency for the detection and unloading die 8 to move away from the winding die 3.

[0022] The winding mold 3 has multiple retractable winding seats 35 on its circumference, each corresponding to the formation of an independent coil. The inspection and blanking mold 8 includes a mounting plate 82, which is slidably connected to a transverse support 80. An extrusion seat 83 and two inspection clamps 84 are fixed on the mounting plate 82. The front end of the extrusion seat 83 has multiple extrusion heads 831 corresponding to the extrusion winding seats. The position of the extrusion seat 83 corresponds to the multiple winding seats 35 on the winding mold 3. The two inspection clamps 84 (which can be pneumatic grippers) are used to clamp the enameled wires at both ends of the multi-coil coil (the wire ends have already been stripped of enameled coating in a previous process; the clamping and inspection positions are the stripped ends).

[0023] The mounting plate 82 is also equipped with a movable fork 85 and a movable fork cylinder 86 that drives it to move along the X-axis. The front end of the movable fork 85 is provided with multiple fork teeth 851, and the number and spacing of the fork teeth 851 correspond one-to-one with the number and spacing of the coils in the multi-coil coil. Accordingly, on the edge of the end face of the winding mold 3 facing the detection and unloading mold 8, there are notches 300 that correspond one-to-one with each fork tooth 851.

[0024] The inspection and unloading process is as follows: Preparation and unloading: After the winding is completed, the transverse cylinder 12 of the winding spindle 1 drives the winding module 11 (which is no longer involved in the winding at this time) to move away from the winding mold 3 along the X-axis, making room; then, the transverse unit 81 drives the transverse support 80 and the detection unloading mold 8 to move along the Y-axis, so that the detection unloading mold 8 enters the space; the transverse cylinder 12 moves and pushes the entire detection unloading mold 8 to overcome the pulling force of the reset unit and slide along the Y-axis on the transverse support 80 until it approaches the winding mold 3. The extrusion seat 83 contacts and extrudes all the winding seats 35, causing them to retract. The extrusion head 831 is inserted into the coil. At the same time, the two detection clamps 84 are activated, clamping the enameled wires at both ends of the multi-connected coil 10 respectively.

[0025] Testing: With the enameled wire clamped in the testing fixture 84, the electrical performance (such as resistance, inter-turn short circuit, etc.) of the multi-connected coil 10 can be tested online through an external testing circuit (not shown in the figure).

[0026] Separation and Discharge: After inspection (or regardless of whether it passes or fails, a unified transfer is performed), the movable fork cylinder 86 drives the movable fork 85 to extend along the X-axis, so that the multiple fork teeth 851 at its front end are precisely inserted into the corresponding notch slots 32 on the end face of the winding mold 3, completing the locking of the coil. Then, the lateral movement cylinder 12 drives the winding module 11 to retract, and the inspection and unloading mold 8 is reset a short distance along the Y-axis under the action of the reset unit. During this process, the fork teeth 851 of the movable fork 85 smoothly peel the multi-connected coil 10 from the winding mold 3 and bring it out, so that the multi-connected coil 10 is completely separated from the area of ​​the winding seat 35. Finally, the lateral movement unit 81 drives the entire lateral movement bracket 80 and the inspection and unloading mold 8 to move along the Y-axis away from the winding mold 3 (i.e., the discharge station), transferring them to the designated location for collection or subsequent processing. The movable fork 85 then retracts, completing one work cycle.

[0027] The winding machine also includes a first cylinder 4 and a second cylinder 5. The first cylinder 4 is vertically mounted on the frame and located directly below the winding mold 3. The second cylinder 5 is vertically mounted on the frame and located directly above the winding mold 3.

[0028] The winding mold 3 includes a base plate 31 and a mold base 32. The base plate 31 is fixedly connected to the movable end of the mold locking sub-shaft 2. The mold base 32 is longitudinally slidably connected to the base plate 31 through a slide rail slider mechanism, and its lower end is driven by the first cylinder 4 to move up and down to adjust its height position.

[0029] The mold base 32 includes a sliding plate 321 on which a left side plate 322, a right side plate 323, a front baffle 324, and a rear baffle 325 are fixed, forming a frame. The front baffle 324 and the rear baffle 325 have openings 326 for the piston rod of the second cylinder 5 to extend into. Multiple second guide grooves 327 are vertically formed on the inner sides of the left side plate 322 and the right side plate 323 to guide the winding plates 33. Multiple winding plates 33 (e.g., six, depending on the number of modules required for the actual motor) are arranged side-by-side in the vertical direction. Each winding plate 33 has second guide blocks 331 on both sides that cooperate with the second guide grooves 327, allowing the winding plates 33 to slide laterally along the second guide grooves 327. The winding plates 33 have slots 332 in the middle of both sides, and limit blocks 333 are fixed to the lower surface of the slots 332. The left side plate 322 and the right side plate 323 are respectively provided with limiting grooves 328 that cooperate with the limiting block 333, and mounting grooves 329 for mounting elastic reset members 34 (such as springs, the number of which can be one or more). The mounting grooves 329 are connected to the limiting grooves 328. One end of the elastic reset member 34 abuts against the top of the mounting groove 329, and the other end is fixed to the limiting block 333, providing a lateral reset force for the winding plate 33. The end of the winding plate 33 facing away from the mold base 32 (i.e., the end facing the winding spindle) is equipped with a winding seat 35 (for easy telescopic movement) through the mounting groove and spring. The mold base 32 is provided with an opening 330 for multiple winding plates 33 to extend out. A winding stop bar 36 is fixed to the edge of the opening 330, and the surface of the opening away from the base plate 31 forms a winding plane. The mold base 32 also has an elongated stepped position 37 adjacent to the opening 330, the length of which is consistent with the sliding direction of the mold base 32. The stepped position 37 is used to accommodate the winding post 392 (described later) of the reserved winding post 39. The opening 330 and the stepped position 37 are separated by a winding stop 36. A first guide block 38 is also provided on the side of the winding plate 33. The mold base 32 has a first guide groove 381 that cooperates with the first guide block 38. The first guide groove 381 communicates with the stepped position 37. The mold base 32 has a specific height position as the winding station. When the winding seat 35 of a winding plate 33 is adjusted to this station, it can be ejected for winding.

[0030] The piston rod end of the second cylinder 5 is equipped with a lifting head (not shown in the figure, which can be set as an annular or semi-annular shape). When a winding plate 33 reaches the winding station, the second cylinder 5 drives the lifting head downward through the opening 326, pressing against the lower part or a specific structure (such as a lifting ramp or arc surface) of the winding plate 33, overcoming the elastic force of the elastic reset member 34, and pushing it out laterally, so that the winding seat 35 on it protrudes from the winding plane, so that the winding spindle 1 can perform the winding operation.

[0031] A wire inlet 6 and a pre-reserved wire winding post 39 are fixed on the base plate 31. The wire inlet 6 is used to guide the enameled wire. The pre-reserved wire winding post 39 is located between the wire inlet 6 and the mold base 32. In this embodiment, the pre-reserved wire winding post 39 includes a vertical plate 391 fixed on the base plate 31, and a hinge seat 393 is installed on the vertical plate 391. A support rod 394 in the shape of an inverted V is hinged to the hinge seat 393 via a hinge shaft. A winding post 392 is fixed to the upper surface of the end of the support rod 394 away from the hinge seat 393, and a trigger protrusion 395 is provided on its side. The middle part of the V-shape of the support rod 394 is connected to the vertical plate 391 through a return spring 396, so that when the support rod 394 is not subjected to external force, the winding post 392 is in a lower initial position (second state) under the tension of the return spring 396, and its top end is not higher than the winding plane. When an external force lifts the protruding edge 395 upwards, the support rod 394 rotates around the hinge axis, and the winding post 392 rises, entering the first state, with its top end higher than the winding plane. The step 37 on the mold base 32 provides a space for the winding post 392 in the second state, ensuring it does not interfere with the movement of the mold base 32. The position of the winding post 392 is offset from the winding station in the lateral (left-right) direction. The position of the triggering protruding edge 395 corresponds to the winding station, so that when the winding plate 33 is lifted to the winding station, the first guide block 38 on it will contact the protruding edge 395 during lateral movement and lift it upwards, thereby raising the winding post 392 into the first state.

[0032] The cable coil is labeled 7, and the reserved cable is labeled 70; Working principle and method: Initial state: The enameled wire passes through the inlet 6 and is held by the chuck of the winding spindle 1. All winding plates 33 are in the reset position under the action of the elastic reset member 34, and the end face of the winding seat 35 on them is not higher than the winding plane. The winding post 392 of the reserved winding post 39 is in the second state, located in the step position 37, and the top end is not higher than the winding plane.

[0033] Wind the first (topmost) coil: Positioning: The first cylinder 4 is activated, lifting the mold base 32 so that the winding seat 35 on the uppermost winding plate 33 is aligned with the winding station.

[0034] Ejection and Triggering: The second cylinder 5 actuates, the lifting head presses down, and the uppermost winding plate 33 is ejected laterally. During the ejection process, the first guide block 38 on the winding plate 33 moves along the first guide groove 381 and lifts the protrusion 395 of the reserved winding post 39, causing the support rod 394 to rotate against the tension of the return spring 396, raising the winding post 392 to the first state (above the winding plane).

[0035] Winding and Reserved Connection: The winding spindle 1 starts and winds the wire onto the protruding winding seat 35 to form the first coil. After winding, the winding spindle 1 pulls the enameled wire to and around the high-positioned winding post 392. This section of enameled wire that passes around the winding post 392 becomes the reserved connecting wire between the first and second coils.

[0036] Winding subsequent coils (taking the second coil as an example): Station switching preparation: The first cylinder 4 is activated again, lifting the mold base 32 by one station distance, so that the winding seat 35 of the second (counting from top to bottom) winding plate 33 is aligned with the winding station.

[0037] Switching and Disengagement: The lifting head of the second cylinder 5 pushes out the second winding plate 33. During this process, as the first winding plate 33 begins to return to its original position laterally under the action of the elastic reset member 34, the pressure of its first guide block 38 on the protruding edge 395 disappears. Under the action of the reset spring 396, the support rod 394 drives the winding post 392 to quickly flip downward, switching from the first state back to the second state. At this time, the enameled wire (reserved wire) originally hanging on the winding post 392 is automatically disengaged due to the rapid descent of the winding post 392 (which follows an arc trajectory), which is the core feature of this structure. At the same time, as the mold base 32 moves, the second winding plate 33 reaches the winding station.

[0038] Re-triggering and winding: During the ejection of the second winding plate 33, the first guide block 38 on it will lift the protrusion 395, causing the winding post 392 to rise back to the first state. The winding spindle 1 winds the second winding seat 35. After winding is completed, the enameled wire is again passed around the now-high winding post 392, forming the reserved wire between the second and third coils.

[0039] Repeat the above "execute subsequent winding process" until all coils are wound.

[0040] The beneficial effects of this winding action are: Achieve fully automated pre-formed wire: Through the pre-formed wire winding post that can be linked to the winding plate, the pre-formed wire is automatically hung, shaped and released during the winding process, completely replacing the traditional manual operation, realizing the full automation of pre-formed wire and significantly improving production efficiency.

[0041] Ensuring consistency of reserved lines: Mechanical linkage ensures that the shape, height, and position of reserved lines are consistent each time they are formed, greatly improving the stability and consistency of product quality.

[0042] The structure is ingenious and the linkage is reliable: the state switching of the reserved winding post is directly triggered by the ejection / reset action of the winding plate. The timing of the action is precisely matched with the winding process. No additional sensors or complex control programs are required. The structure is simple and compact and the operation is reliable.

[0043] Adaptable to multi-station continuous winding: The high integration of functions such as mold seat lifting, selective ejection of winding plate, and automatic forming of reserved wire enables efficient and orderly completion of continuous winding of multiple coils with a high degree of automation.

[0044] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
