Description

TECHNICAL FIELD

[0001] The utility model relates to the motor field, specifically, especially, it is a kind of positive and negative straight winding bobbin, motor, camera and electronic equipment. BACKGROUND

[0002] In precision electronic products such as mobile phone camera module, voice coil motor (VCM) as the important component of driving focusing, its winding process directly determines the advantages and disadvantages of motor performance and cost level.Current VCM winding mode on the market is mainly divided into side winding and straight winding two ways, both have their own merits, but also face their own limitations and challenges.

[0003] Side winding process is usually applied to VCM motor, although it can meet the miniaturization demand of product in certain specific circumstances, but its shortcomings are also obvious.First, since the coil needs to be wound on the side, the process flow is more complicated, which affects the production efficiency and increases the production and material cost per unit product.

[0004] Compared with the side, straight winding is more intuitive and simple in operation, however, its biggest shortcoming is that only single current direction can be formed, which means that in the complex application scene requiring bidirectional current driving, such as realizing lens fast focusing or reverse movement function, the traditional straight winding is insufficient.This limitation of winding mode restricts the function expansion of VCM motor, and cannot meet the diversified demand of motor performance of high-end smart phones and other products. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides a kind of positive and negative straight winding bobbin, motor, camera and electronic equipment, and wire rack body is equipped with multiple interval distribution winding slot, cleverly set commutating post between adjacent two slots, change winding direction, realize the current direction of coil wound in adjacent winding slot opposite each other, by reasonably assembling magnet, so that the direction of ampere force generated by all winding slots after coil energization is consistent, to realize bidirectional current driving.

[0006] The utility model aims to realize the following technical scheme:

[0007] A kind of positive and negative straight winding bobbin, including wire rack body, winding slot set in wire rack body and commutating post set in wire rack body, the coil is wound in the winding slot, the winding slot has multiple, multiple winding slots are interval distribution, there is gap between adjacent two winding slots, the commutating post is set in the gap, the current direction of coil wound in two adjacent winding slots is opposite each other after passing through commutating post.

[0008] The wire frame body is equipped with a plurality of spaced-apart winding grooves, and by skillfully arranging a reversing column between two adjacent grooves, a coil is wound in each winding groove. When the number of turns of the winding in a winding groove reaches the required number, the wire is wound in the reversing column to change the winding direction. Only a slight rotation of the jig clamping the wire frame body is needed, and no complex switching action is required to change from clockwise to counterclockwise or vice versa. This greatly simplifies the operation process, greatly shortens the production time, improves the winding speed and continuity, and through reasonable assembly of the magnet, the directions of the ampere forces generated by all the winding grooves are consistent when the coil is energized, thereby realizing bidirectional current driving.

[0009] To meet the needs of more diverse coil configurations, the winding frame supports the construction of double-layer or even multi-layer winding grooves. When the demand for ampere force is not met, the number of winding groove layers can be increased to expand the capacity of the coil, thereby meeting the needs of designers and providing engineers with greater design freedom, suitable for a wider range of electronic devices and application scenarios.

[0010] Compared with the traditional side winding method, the forward and reverse straight winding process does not require complex reversing process and does not need to prevent the winding from exceeding the predetermined height, significantly reducing the invalid working hours during winding, achieving a leap in automation, greatly reducing the manual intervention required for a single product, and significantly improving the output per unit of time.

[0011] Preferably, the winding groove is dug around the wire frame body.

[0012] The winding grooves are arranged in a ring along the side wall of the wire frame body, and the winding grooves and the wire frame body form an integral whole, reducing the need for additional supports or accessories and reducing material costs.

[0013] Preferably, the reversing column is provided with a receiving groove for accommodating the coil.

[0014] The design of the receiving groove aims to provide precise guidance and firm fixation for the coil. When the coil is wound around the reversing column, it can smoothly reverse and turn into the next winding groove without twisting or loosening. By adding a receiving groove to the reversing column, the coil can be better managed during winding, avoiding the coil from falling off the top of the reversing column due to external factors after completing the turning around the reversing column, thereby improving the stability of the product. The presence of the receiving groove gives the reversing column higher stability, allowing the same device to adapt to different types and specifications of coil winding requirements. Whether it is a wire of different thickness or a complex winding pattern, it can be handled with ease. This high adaptability allows the enterprise to make adjustments faster when facing changes in market demand, and to cope with diversified order challenges.

[0015] Preferably, the two adjacent winding grooves are parallel to each other.

[0016] The adjacent winding grooves are parallel to each other, avoiding the problem that the angle deviation of the ampere force generated by different winding grooves after power-on causes a large difference between the actual resultant force and the expected force, ensuring the uniformity and stability of the structure of the coil, avoiding the crossing and overlapping of the coils, and laying a foundation for the uniform distribution and compact winding of the coils.

[0017] Preferably, the wire hanging column is arranged on the wire rack body, and the starting wire end and the terminal wire end of the coil are fixed on the wire hanging column.

[0018] The wire hanging column provides a reliable fulcrum to ensure the stability of the coil during winding. It tightly holds the starting wire end of the coil, just like an anchor, and can keep the position of the coil stable even in the case of high-speed winding or external disturbance, avoiding the risk of coil disorder caused by wire slipping or wire breakage caused by excessive tension, significantly improving the safety and reliability of coil winding. The addition of the wire hanging column makes the winding operation more convenient. Workers or automated equipment only need to hang one end of the coil on the column to start orderly winding, saving the time for frequent manual fixing and adjustment, greatly facilitating the installation and disassembly of the coil, and reducing the frequency of manual intervention. For automated production lines, this feature is particularly prominent, enabling seamless connection and rapid switching, greatly accelerating the production rhythm.

[0019] Preferably, one or more reversing columns are arranged at the gap between the two adjacent winding grooves.

[0020] The reversing column is ingeniously arranged in the gap between the winding grooves. After the wire is wound in a certain winding groove, it can quickly change direction and smoothly transition to the next winding groove by winding and fixing with the reversing column, forming a smooth and uninterrupted winding path. This design overcomes the problem of manual adjustment or machine stop in traditional winding to change the winding area, greatly simplifying the operation process and improving the winding efficiency. The precise setting of the reversing column can realize the turning of the coil and also ensure the stability of the winding groove of the previous layer, avoiding the problem of loose wire caused by unstable factors and maintaining the consistency of the overall shape and geometric size of the coil. This is crucial for the production of high-quality coils, especially for high-end electronic components that require high precision. By reasonably planning the position of the reversing column in a limited space, the winding rack achieves a compact and efficient layout, making each winding groove fully functional, reducing space waste, and increasing the volume efficiency of the winding rack.

[0021] Preferably, the wire hanging column is located at the bottom of the wire rack body, and the starting wire end of the coil in the winding groove near the wire hanging column is directly fixed on the wire hanging column. After the winding of the wire groove is completed, the wire is fixed by winding around the reversing column and then pulled to the wire hanging column for winding and fixing to end the winding.

[0022] The hanging wire column is located at the bottom of the wire frame and serves as the starting and ending point of winding, which can provide a stable base for the coil. After the wire slot is completely wound, it is first wound on the reversing column and then fixed to the hanging wire column, which injects flexibility into the winding process. The reversing column serves to change direction and acts as a relay point to balance the process of transferring the coil from one winding slot to another, ensuring smooth and efficient movement of the coil, while also avoiding physical damage to the coil during winding.

[0023] Another implementation of the present patent is a motor comprising the forward and reverse straight winding frame as described above.

[0024] Another implementation of the present patent is a camera comprising the motor as described above.

[0025] Another implementation of the present patent is an electronic device comprising the camera as described above.

[0026] The beneficial effects of the present utility model compared to the prior art are:

[0027] The forward and reverse straight winding frame of the present utility model is equipped with multiple spaced winding slots, a reversing column is ingeniously arranged between adjacent two slots, and coils connected in series are wound in each winding slot. When the number of turns of winding in a winding slot reaches the requirement, the wire can be wound in the reversing column to change the winding direction, i.e. only a slight rotation of the jig clamping the wire frame body is needed, and complex switching actions are no longer required, which can change from clockwise to counterclockwise, or vice versa, greatly simplifying the operation process, greatly shortening the production time, improving the winding speed and continuity, and realizing bidirectional current driving.

[0028] To meet the needs of more diversified coil structures, the winding frame supports the construction of double-layer or even multi-layer winding slots, which not only expands the capacity of the coil, but also provides engineers with greater design freedom, suitable for a wider range of electronic devices and application scenarios.

[0029] Compared with the traditional side winding method, the forward and reverse straight winding process significantly reduces the invalid working hours in the winding process, realizes a leap in automation, greatly reduces the manual intervention required for a single product, and significantly improves the output per unit of time.

[0045] In the embodiment, the winding grooves 20 are arranged around the frame body 10.

[0047] In the embodiment, the commutating column 30 is provided with a containing groove 31 for containing the coil.

[0048] The design of the accommodating groove 31 aims to provide precise guidance and firm fixation for the coil. When the coil passes through the reversing column 30, it can smoothly reverse into the next winding groove 20 without twisting or loosening.
