Description

Technical Field

[0001] The present invention relates to the field of motor stator winding processing, and in particular to multi-segment wire winding equipment and a system. Background Art

[0002] The motor stator includes an iron core, wire slots arranged in the iron core, and coil windings embedded in the wire slots. Therefore, during the stator manufacturing process, the enameled wire needs to be wound by a winding machine to form a coil winding, and then the coil winding is transferred to the mold head of the coil embedding machine, and the coil winding is embedded into the wire slots on the iron core through the mold head.

[0003] The winding machine provided by the prior art is provided with a plurality of winding molds corresponding to the number of coil windings to be wound, and each winding mold forms a certain height difference in the vertical direction, so as to facilitate the winding of the winding machine. After the winding is completed, there is a certain height difference between each coil winding in the vertical direction.

[0004] The coil embedding machine mold head is provided with a plurality of wire mold top blocks for inserting the coil winding, and through grooves are formed between the wire mold top blocks for inserting the coil winding. A plurality of wire mold top blocks are surrounded to form a cylinder, and the cylinder can be inserted into the through hole in the middle of the iron core, so that the coil winding inserted on the wire mold top block can be embedded in the iron core wire groove. The winding mold de-wire method provided by the prior art is: the coil winding part of the winding mold is sunk into the mold head, and then the central cylinder pushes the coil winding into the wire mold top block to achieve the de-wire effect.

[0005] In the coil winding de-wire method provided by the prior art, it is required that the height of the wire die top block on the mold head of the coil embedding machine is greater than the sum of the heights of all winding molds, so that all coil windings can be easily embedded in the mold head. However, with the development of motor products, stator products with thick wire diameter and low stacking thickness, such as new energy motors, are gradually increasing. When de-wireing the stator of this new motor, the problem of insufficient strength of the mold head is prone to occur when the height of the wire die top block is too large. Therefore, in order to cope with this trend, the coil embedding machine mold head needs to be lowered in height to increase its strength. However, the winding de-wire method provided by the prior art determines that the height to which the mold head needs to be lowered is limited, and its optimization effect on the structural strength is limited. Summary of the invention

[0006] In view of the problem that in the existing stator processing process, the height of the mold head needs to be lowered to enhance its structural strength, the embodiment of the present application provides a multi-segment wire winding machine, and a winding system formed by using the multi-segment wire winding machine and the mold head with the height lowered, so that the height of the wire mold top block of the mold head can be no lower than the height of the winding mold, and does not need to reach the sum of the heights of all winding molds.

[0007] The multi-segment wire winding machine provided in the embodiment of the present application includes: a winding machine frame, at least two groups of winding module groups arranged on the winding machine frame, each group of winding module groups includes a driving component, a winding mold and a temporary locking mechanism, the winding mold is connected to the driving component, the driving component drives the winding mold to move up and down relative to the winding machine frame, and allows different winding molds to be misaligned in the upper and lower positions, the temporary locking mechanism is used to temporarily lock the winding mold in the upper and lower misaligned positions when winding, and when the wire is off-line, the winding mold can be returned to the same height by unlocking the temporary locking mechanism in sequence.

[0008] The multi-segment wire winding machine provided in the embodiment of the present application improves the winding die set of the winding machine, and 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 it after reaching a certain position, so that the driven winding die protrudes from other winding die sets, which is convenient for the winding of the enameled wire. When one group of coil windings is completed, the next group of winding die sets drives the winding die to protrude more than the previous group of winding die sets, forming an upper and lower misalignment and locking the position through a temporary locking mechanism, which is convenient for the winding of the next group of coil windings. The multi-segment wire winding machine provided in the present application provides a new way for subsequent decoupling, so that the height of the wire die top block on the mold head can be reduced when decoupling, thereby improving the strength of the mold head.

[0009] Based on the same purpose, an embodiment of the present application provides a multi-segment wire winding and de-wireing system, including the multi-segment wire winding machine as described above, and also including a coil embedding machine, the coil embedding machine is provided with a mold head, the mold head includes a plurality of wire mold top blocks, the plurality of wire mold top blocks are arranged in a ring shape to form a hollow cylinder, and through grooves for interlacing common coil windings are provided between the wire mold top blocks. Assuming the height of the wire mold top block is h1, and the height of the winding mold is h2, then h2≤h1≤1.5h2 is satisfied.

[0010] The multi-segment wire winding and de-wire system provided in this embodiment can wind the coil windings on the winding molds in sections and temporarily lock their positions by improving the structure of the multi-segment wire winding machine. After the coil windings are wound on all the winding molds, the entire winding machine frame is placed above the coil embedding machine mold head, and the entire winding machine frame is driven to move downward. When the winding molds of the bottom group of winding mold groups contact the mold head, their coil windings will be inserted into the wire mold top block. At this time, the temporary locking mechanism is unlocked, so that the winding molds of the bottom group of winding mold groups can move upward relative to the winding machine frame under the drive of the winding machine frame, until the winding molds of the next group of winding mold groups contact the mold head, and the temporary locking mechanism thereon is unlocked, and the process of the previous group of winding molds is repeated. Until the coil windings on all winding molds are embedded in the wire mold top block on the mold head. Through the above improvements, the height of the wire die top block on the die head only needs to be slightly higher than the height of one group of winding dies to achieve the entire wire removal process, and does not need to be higher than the sum of the heights of all winding dies. In this way, the height of the wire die top block on the die head is greatly reduced, which can enhance its structural strength, meet the existing thick wire diameter, low stacking motor stator production requirements, and reduce its production cost.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 5As shown, an embodiment of the present application provides a multi-segment wire winding and de-winding system, including a multi-segment wire winding machine 1 and a coil embedding machine 2.

[0033] The multi-segment wire winding machine 1 provided in the embodiment of the present application comprises a winding machine frame 10, at least two groups of winding module groups 11 arranged on the winding machine frame, each group of winding module groups comprises a driving component, a winding mold and a temporary locking mechanism, the winding mold is connected to the driving component, the driving component drives the winding mold to move up and down relative to the winding machine frame 10, and allows different winding molds to be misaligned in the upper and lower positions, the temporary locking mechanism is used to temporarily lock the winding mold in the upper and lower misaligned positions during winding, and when the wire is off-line, the winding mold can be returned to the same height by unlocking the temporary locking mechanism in sequence.

[0034] The coil embedding machine 2 provided in the example of the present application is provided with a mold head 21, and the mold head 21 includes a plurality of wire mold top blocks 211, and the plurality of wire mold top blocks 211 are arranged in a ring shape to form a hollow cylinder, and through grooves 212 for interlacing common coil windings are arranged between the wire mold top blocks 211. Assuming that the height of the wire mold top blocks is h1 and the height of the winding mold is h2, then h2≤h1≤1.5h2 is satisfied.

[0035] The winding and de-wireing system for a multi-segment wire winding machine provided in the embodiment of the present application has made improvements to the multi-segment wire winding machine and the coil embedding machine. Among them, the multi-segment wire winding machine improves the winding module of the winding machine, and the winding module has a driving mechanism and a temporary locking mechanism. The driving mechanism can drive the winding module to move downward and temporarily lock it after reaching a certain position, so that the driven winding module protrudes from other winding modules, which is convenient for winding the enameled wire. The working principle of the multi-segment wire winding and de-wireing system provided in the present application is explained as follows. Figure 1As shown, three groups of winding molds are used as an example for explanation. First, the first group of winding molds winds the coil windings. That is, the first winding mold 116-1 is extended, and its position is locked by a temporary locking mechanism, and then the first winding mold 116-1 is wound with a predetermined number of turns of coil windings; after the first group of coil windings are wound, the second winding mold 116-2 is extended to protrude from the first winding mold 116-1 to form an upper and lower misalignment, and its position is locked by a temporary locking mechanism, and then the second winding mold 116-2 is wound with a predetermined number of turns of coil windings; finally, the third winding mold 116-3 is extended to protrude from the second winding mold 116-2 to form an upper and lower misalignment, and its position is locked by a temporary locking mechanism, and then the third winding mold 116-3 is wound with a predetermined number of turns of coil windings. When the coil windings are wound on all winding molds, the entire winding machine frame is placed above the coil embedding machine mold head, and the entire winding machine frame is driven to move downward. When the winding mold of the bottom winding mold group (i.e., the third winding mold 116-3) contacts the mold head 21, its coil winding will be inserted into the wire mold top block 211. At this time, the temporary locking mechanism is unlocked, so that the winding mold of the bottom winding mold group can move upward relative to the winding machine frame under the drive of the winding machine frame, until the winding mold of the next winding mold group contacts the mold head, and the temporary locking mechanism on it is unlocked, and the process of the previous winding mold group is repeated. This continues until the coil windings on all winding molds are embedded in the wire mold top block on the mold head, as shown in FIG. Figure 4 As shown, at this time, all winding dies are on the same horizontal plane. Thanks to the improvement of the multi-segment winding machine, the die head of the coil embedding machine has also been improved, and the height of its wire die top block is greatly reduced compared with the height of the wire die top block in the original die head.

[0036] For example, if the original multi-segment winding machine is equipped with three winding mold groups, its de-wire method requires that the height of the wire mold top block must be at least the height of three winding molds, that is, if the height of one winding mold is set to h2, and the height of the wire mold top block is set to h1, the height of h1 must be at least not less than 3h2. Through the above improvements, the height of the wire mold top block on the mold head only needs to be not less than the height of one of the winding molds, that is, h1 only needs to be not less than h2 to achieve the entire de-wire process. In this way, the height of the wire mold top block on the mold head is greatly reduced, and its structural strength can be enhanced to meet the existing thick wire diameter and low stacking motor stator production requirements.

[0037] The technical solution provided by the present application focuses on providing a new winding and de-winding method, that is, first temporarily fix the position of a winding mold and wind the coil winding, and then temporarily lock the position of the second winding mold and wind the coil winding. Until all winding molds are wound with coil windings. De-winding is the opposite. The winding mold that winds the coil windings last is de-wired, and then its position is unlocked until all winding molds are de-wired, and then the winding molds are locked in position as a whole. The stator winding and de-winding methods based on this implementation method are all technical solutions protected by this application, and are not limited to the specific implementation methods provided by this application.

That is, the clutch device controls the drive shaft to be connected to only one of the wire die slides at a time. At this time, the temporary locking structure of the wire die slide connected to the drive shaft is in an unlocked state, so that it can move up and down under the drive of the cylinder, while the remaining wire die slides are locked by the temporary locking mechanism. After the wire die slide is driven to the specified position, the wire die slide is locked by the temporary locking mechanism to keep its position stationary, the drive shaft of the main cylinder is retracted, and the above process is repeated with other wire die slides through the clutch device to achieve driving all wire die slides to the specified position.
