Description

TECHNICAL FIELD

[0002] The motor stator includes the core, the wire slot in the core is arranged and the coil winding embedded in the wire slot. Therefore, in the stator processing process, the enameled wire needs to be wound first through the winding machine, the coil winding is formed, then the coil winding is transferred to the mold head of the coil embedding machine, and the coil winding is embedded into the wire slot on the core through the mold head.

[0003] The prior art provides the winding machine, which is provided with a plurality of winding molds corresponding to the number of coil windings to be wound according to the needs, and each winding mold forms a certain drop in the vertical direction, thereby facilitating the winding of the winding machine. After winding, there is a certain height difference between each coil winding in the vertical direction.

[0004] The mold head of the coil embedding machine is provided with a plurality of wire mold top blocks for the coil winding to be inserted, and the wire mold top blocks form a through slot for the coil winding to be inserted. The plurality of wire mold top blocks form a cylinder, and the cylinder can be inserted into the through hole in the middle of the core, so as to embed the coil winding inserted into the wire mold top block into the wire slot of the core. The winding mold of the prior art provides a wire stripping method: the coil winding part of the winding mold is sunk into the mold head, and then the coil winding is pushed into the wire mold top block by the center cylinder, so as to achieve the effect of wire stripping.

[0005] In the wire stripping method provided by the prior art, the height of the wire mold top block on the mold head of the coil embedding machine is required to be greater than the sum of the heights of all winding molds, so that all coil windings can be embedded into the mold head. However, with the development of motor products, such as new energy motor and other thick wire diameter low stacking thickness stator products gradually increase. When stripping the coil winding of the new motor stator, the wire mold top block with excessive height is prone to have insufficient strength of the mold head. Therefore, in order to cope with this trend, the mold head of the coil embedding machine needs to be lowered in height to increase the structural strength. However, the wire stripping method provided by the prior art determines that the height of the mold head to be lowered is limited, and the optimization effect on the structural strength is limited. UTILITY MODEL CONTENTS

[0007] The multi-section wire winding machine provided by the embodiment of the present application comprises a winding machine rack, at least two groups of winding die sets arranged on the winding machine rack, each group of winding die sets comprising a driving assembly, a winding die and a temporary locking mechanism, the winding die being connected to the driving assembly, the driving assembly driving the winding die to move up and down relative to the winding machine rack, and enabling different winding dies to be staggered in up and down positions, and the temporary locking mechanism being used to temporarily lock the winding die in the up and down staggered positions during winding, and enabling the winding die to return to the same height by sequentially unlocking the temporary locking mechanism during unwinding.

[0008] The multi-section wire winding machine provided by the embodiment of the present application improves the winding die set of the winding machine, the winding die set has a driving mechanism and a temporary locking mechanism, the driving mechanism can drive the winding die to move downward and temporarily lock when reaching a certain position, thereby enabling the driven winding die to protrude other winding dies, facilitating the winding of the enameled wire. After a group of coil windings is wound, the winding die of the next group of winding die sets is driven to protrude more than the winding die of the previous group, forming up and down stagger and being position-locked by the temporary locking mechanism, facilitating the winding of the next group of coil windings. The multi-section wire winding machine provided by the present application provides a new way for subsequent unwinding, thereby enabling the height of the wire die top block on the die head to be reduced during unwinding, thereby improving the strength of the die head.

[0010] The multi-section wire winding and unwinding system provided by the embodiment can segmentally wind the coil winding on the winding mold and temporarily lock the position. After winding the coil winding on all winding molds, the whole winding machine frame is placed above the mold machine head of the coil embedding machine and is driven to move downward. When the winding mold of the last winding mold group contacts the mold machine head, the coil winding is embedded on the wire mold top block. At this time, the temporary locking mechanism is unlocked, so that the winding mold of the last winding mold group can move upward relative to the winding machine frame under the driving of the winding machine frame until the winding mold of the next winding mold group contacts the mold machine head, the temporary locking mechanism is unlocked, and the process of the previous winding mold group is repeated. Until the coil winding on all winding molds is embedded on the wire mold top block of the mold machine head. Through the above improvement, the height of the wire mold top block on the mold machine head only needs to be slightly higher than the height of one of the winding molds, so that the whole unwinding process can be realized without being higher than the sum of the heights of all winding molds.

[0031] The embodiments of the present application will be described in detail below in combination with the drawings.

[0032] AsFigures 1 to 5 As shown, the embodiment of the present application provides a multi-section wire winding and unwinding system, which comprises a multi-section wire winding machine 1 and a coil embedding machine 2.

[0033] The multi-section wire winding machine 1 provided by the embodiment of the present application comprises a winding machine rack 10, at least two groups of winding mold groups 11 arranged on the winding machine rack, each group of winding mold groups comprising a driving assembly, a winding mold and a temporary locking mechanism, the winding mold being connected to the driving assembly, the driving assembly driving the winding mold to move up and down relative to the winding machine rack 10, and enabling different winding molds to be staggered in up and down positions, and the temporary locking mechanism being used to temporarily lock the winding mold in the up and down staggered positions during winding, and through sequentially unlocking the temporary locking mechanism, the winding mold can return to the same height during unwinding.

[0034] The coil embedding machine 2 provided by the example of the present application is provided with a mold head 21, the mold head 21 comprising a plurality of wire mold top blocks 211, the plurality of wire mold top blocks 211 being arranged in a ring shape to form a hollow column, the wire mold top blocks 211 being provided with through grooves 212 for inserting common coil windings, the height of the wire mold top block being h1, the height of the winding mold being h2, and h2≤h1≤1.5h2 being satisfied.

[0035] The multi-section wire winding and unwinding system provided by the embodiment of the present application improves the multi-section wire winding machine and the coil embedding machine respectively. Among them, the multi-section wire winding machine improves the winding mold group of the winding machine, the winding mold group has a driving mechanism and a temporary locking mechanism, the driving mechanism can drive the winding mold to move downward and temporarily lock after reaching a certain position, so that the driven winding mold protrudes from other winding molds, facilitating the winding of the enameled wire. The following describes the action principle of the multi-section wire winding and unwinding system provided by the present application. As shown in the figure, Figure 1As shown, the following explanation uses a three-unit winding module as an example. First, the first winding module winds the coil winding. Specifically, the first winding mold 116-1 extends out and is locked in position by a temporary locking mechanism. Then, a predetermined number of turns of coil winding is wound on the first winding mold 116-1. After the first coil winding is completed, the second winding mold 116-2 extends out, protruding from the first winding mold 116-1 in a vertically offset manner. Its position is locked again by a temporary locking mechanism. Then, a predetermined number of turns of coil winding is wound on the second winding mold 116-2. Finally, the third winding mold 116-3 extends out, protruding from the second winding mold 116-2 in a vertically offset manner. Its position is locked again by a temporary locking mechanism. Then, a predetermined number of turns of coil winding is wound on the third winding mold 116-3. After all the winding molds have been wound with coil windings, the entire winding machine frame is placed above the coil embedding machine mold head, and the entire winding machine frame is driven downwards. When the winding die of the last winding module (i.e., the third winding die 116-3) contacts the die head 21, its coil winding will be fitted onto the die top block 211. At this time, the temporary locking mechanism unlocks, allowing the winding die of the last winding module to move upward relative to the winding machine frame under the drive of the winding machine frame, until the winding die of the next winding module contacts the die head, at which point the temporary locking mechanism on it unlocks, and the process of the previous winding module is repeated. This continues until the coil windings on all winding dies are embedded into the die top block on the die head, such as... Figure 4 As shown, at this point, all the winding dies are on the same horizontal plane. Thanks to the improvements to the multi-segment winding machine, the die head of the coil embedding machine has also been improved, with the height of its die top block being significantly reduced compared to the original die head.

[0036] In the case of a traditional multi-segment winding machine with three winding modules, the wire removal method requires the height of the wire mold top block to be at least the sum of the heights of the three winding dies. That is, if the height of one winding die is h2 and the height of the wire mold top block is h1, then h1 must be at least 3h2. However, with the improvement described above, the height of the wire mold top block on the die head only needs to be at least the height of one of the winding dies; that is, h1 only needs to be at least h2 to complete the entire wire removal process. This significantly reduces the height of the wire mold top block on the die head, enhancing its structural strength and meeting the current requirements for manufacturing stators for large-diameter, low-stack motors.

[0037] The technical scheme provided by the application focuses on providing a new winding and unwinding mode, that is, temporarily fixing the position of a winding mold and winding the coil winding, then temporarily locking the position of a second winding mold and winding the coil winding, and winding the coil winding on all winding molds. The unwinding is opposite, starting from the winding mold where the coil winding is wound last, unlocking the position, and then locking the position of the winding mold after all winding molds are unwound. The stator winding and unwinding mode based on this implementation mode is the technical scheme protected by the application, and is not limited to the specific implementation mode provided by the application.

[0038] The implementation mode of the winding mold group, the driving mechanism, the winding mold, and the temporary locking mechanism provided by the application can include various modes, such as motor driving and pin locking.
