Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone linear motors, and in particular to a rotating shaft assembly for correcting the upper housing. Background Art

[0002] The upper housing is an important component of a mobile phone linear motor, and it can cooperate with the lower housing to protect the motor. The upper housing is mostly a cylindrical cover structure, which has a receiving cavity for accommodating the mover (leaf spring, vibrator, magnetic conductive sleeve and magnetic steel) and the stator (FPC (flexible printed circuit board) flexible wiring piece and coil), and a receiving opening communicating with the receiving cavity is provided at the bottom end. The lower housing mostly includes a disc-shaped housing, and a connecting piece extending radially outward is provided on the side wall of the housing. The housing can cover the receiving opening. To improve the connection stability between the upper housing and the lower housing, a plurality of outwardly extending housing protrusions are usually provided on the side wall of the lower housing, and a housing notch that can cooperate with the connecting piece and the housing protrusions is provided at the receiving opening of the upper housing.

[0003] When assembling a mobile phone linear motor, usually the mover and the lower housing assembly are assembled first, and then the upper housing is assembled on the aforementioned semi-finished product. In this way, the housing notch on the upper housing needs to be located at a specific circumferential position so as to match the connecting piece and each housing protrusion on the lower housing. At present, it is mostly adjusted manually to adjust the circumferential position of the upper housing and then transferred to the next working station. It can be seen that such an operation with a low degree of automation will not only increase the labor intensity of the operator, but also greatly affect the assembly efficiency. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above problems of the prior art, and provide a rotating shaft assembly for correcting the upper housing, which can accurately correct the circumferential position of the upper housing. In this way, the workload of the operator can be effectively reduced and the production efficiency can be improved.

[0005] The purpose of the present invention is mainly achieved through the following technical solutions:

[0006] The rotating shaft assembly for correcting the upper housing includes a movable rod and a rotating sleeve sleeved on the periphery of the movable rod;

[0007] An inner positioning member is provided on the movable rod, and an inner elastic member is provided between the bottom end of the inner positioning member and the top end of the rotating sleeve;

[0008] The top end of the movable rod is connected through an inner upper connecting member with an inner correction sleeve that can rotate relative to the movable rod;

[0009] An outer correction sleeve that rotates synchronously with the rotating sleeve is sleeved on the rotating sleeve. A plurality of correction strips protruding above the outer correction sleeve are provided on the outer correction sleeve, and the plurality of correction strips are located on the periphery of the inner correction sleeve;

[0010] The middle part of the rotating sleeve is provided with an outwardly protruding external positioning piece, and an external elastic piece is arranged between the top end of the external positioning piece and the bottom end of the external correction sleeve;

[0011] The outer elastic member is used to support the outer correction sleeve and enable the outer correction sleeve to move up and down relative to the rotating sleeve;

[0012] The inner elastic member is used to support the movable rod, so that: the inner correction sleeve and the outer correction sleeve are arranged at a distance, and the movable rod can move up and down relative to the rotating sleeve.

[0013] In the present invention, the number and position of the correction strips should correspond to the shell notches of the upper shell, the outer diameter of the inner correction sleeve should be adapted to the inner diameter of the upper shell, and when the upper shell is sleeved on the inner correction sleeve, the shell notches can be inserted and matched with the corresponding correction strips. When the present invention is applied, the rotating sleeve can be rotatably connected to the correction support seat through the bearing, so that the correction support seat can support the rotating sleeve, and the rotating sleeve can also rotate.

[0014] When correction work is required, the upper housing to be corrected is moved to the inner correction sleeve by the manipulator, and the upper housing is moved down so that its accommodating cavity is set on the inner correction sleeve. Since the circumferential position of the upper housing is randomly placed, at this time, each housing notch is very likely to be staggered with each correction strip in the circumferential direction. At this time, the downward external force of the upper housing is continued to be maintained, so that: the outer correction sleeve can compress the outer elastic part to move downward. Then apply a rotating external force to the rotating sleeve to make it rotate. At this time, the outer correction sleeve will rotate with the rotating sleeve. Under the action of the downward external force, the upper housing will rotate relative to the outer correction sleeve. When the correction strip of the outer correction sleeve moves to the position corresponding to the housing notch, the outer correction sleeve will move up under the action of the outer elastic part. At this time, the correction strip will be inserted into the housing notch. At this time, the downward external force is released, and the upper housing will rotate with the outer correction sleeve until it reaches a specific circumferential position, that is, the correction work before the upper housing is loaded is completed. Finally, the corrected upper casing is directly taken out by the robot and entered into the next process.

[0015] The inner elastic part can not only support the movable rod, but also enable the inner correction sleeve and the movable rod to move up and down relative to the rotating sleeve, so that the downward external force can be buffered to avoid damage to the upper housing. Through the setting of the inner and upper connecting parts, the inner correction sleeve and the movable rod can rotate independently in the circumferential direction. In this way, when the shell notch and the correction strip are inserted and matched, the outer correction sleeve can easily drive the upper housing to rotate, which can effectively improve the reliability of operation.

[0016] In order to reduce the mutual wear between the inner correction sleeve and the correction strip, further, the inner surface of the correction strip is adapted to the outer surface of the inner correction sleeve.

[0017] A gap may be provided between the inner correction sleeve and the correction strip, but the gap should be smaller than the thickness of the bottom end of the upper housing.

[0018] To improve the stability of the up-and-down movement of the movable rod, further, when the inner elastic member supports the movable rod, the upper end portion and the lower end portion of the movable rod respectively pass through the top opening and the bottom opening of the rotating sleeve;

[0019] The lower end portion of the movable rod is connected with an inner lower connecting member that can rotate relative to the movable rod.

[0020] In the present invention, the inner lower connecting member can be connected to the correction support base, so that the movable rod can be well limited, and its shaking and jitter during operation can be avoided.

[0021] To prevent the movable rod from moving excessively, further, the lower end portion of the movable rod is connected with an up-and-down limiting member.

[0022] Through the cooperation between the up-and-down limiting member and the correction support base, the limit position of the downward movement of the movable rod can be defined.

[0023] Further, an outer connecting member that can rotate relative to the outer positioning member is sleeved on the outer positioning member.

[0024] In the present invention, it can be connected to the correction support base through the outer connecting member.

[0025] To facilitate applying a rotational external force to the rotating sleeve, further, a transmission gear is connected to the rotating sleeve.

[0026] Further, a protective sleeve located between the transmission gear and the outer positioning member is also sleeved on the rotating sleeve.

[0027] To implement the setting of the inner positioning member, further, a positioning annular groove is formed on the movable rod, and the inner positioning member is clamped in the annular groove.

[0028] Further, when the outer elastic member supports the outer correction sleeve, the top end of the outer correction sleeve is located above the top end of the rotating sleeve;

[0029] The lower end portion of the inner elastic member is located within the area surrounded by the outer correction sleeve.

[0030] In the present invention, the outer correction sleeve can limit the inner elastic member to prevent it from moving accidentally during operation.

[0031] Further, a correction annular groove is provided on the inner wall surface of the outer correction sleeve, and the upper end portion of the outer elastic member is located within the area surrounded by the correction annular groove.

[0032] In the present invention, the correction outer groove can limit the outer elastic member to prevent it from moving accidentally during operation.

[0033] The present invention has the following beneficial effects:

[0034] 1. In the present invention, through the setting of the inner correction sleeve, it can be used to support the upper casing; through the setting that the outer correction sleeve can move up and down and rotate, the circumferential position of the upper casing can be accurately corrected. In this way, the workload of the operator can be greatly reduced, and at the same time, the production efficiency can also be improved.

[0035] 2. The inner elastic member can not only support the movable rod, but also enable the inner correction sleeve and the movable rod to move up and down relative to the rotating sleeve. In this way, the downward external force can be buffered to avoid damaging the upper casing.

[0036] 3. Through the setting of the inner upper connecting member, the inner correction sleeve and the movable rod rotate independently in the circumferential direction. In this way, when the notch of the casing is inserted and matched with the correction strip, the outer correction sleeve can easily drive the upper casing to rotate, which can effectively improve the reliability of operation.

[0037] 4. The inner lower connecting member can be connected to the correction support base, so that the movable rod can be well limited, avoiding shaking and jitter during operation.

[0038] 5. In the present invention, the correction outer groove can limit the outer elastic member to prevent it from moving accidentally during operation. BRIEF DESCRIPTION OF THE DRAWINGS
