Description

Base integrated with coil, production process thereof and voice coil motor

Technical Field

The invention relates to a base integrated with a coil, a production process thereof and the technical field of a voice coil motor, in particular to a base for the field of electronic equipment, a production process thereof and a voice coil motor.

Background

A conventional base and voice coil motor having a coil generally include a base, a metal circuit injection-molded in the base, an electronic component welded to the metal circuit, a coil formed by winding or mounted and assembled, and a driving element such as a magnetic structure interacting with the coil. Generally, an assembler of the voice coil motor needs to electrically assemble the basic components, in order to match the layout and installation requirements of various components, the layout difficulty of each component is generally high, and some additional assembly space needs to be reserved for the adapting component, such as a Flexible Printed Circuit (FPC) requiring an integrated IC or a coil, at least a portion of a vertical space needs to be reserved, and an assembly space for the integrated IC or the coil and the FPC needs to be designed.

For example, a voice coil motor generally adopts a Flexible Printed Circuit (FPC) surface assembly process to dispose a coil on a Flexible circuit board and solder the coil to a metal circuit in a base to achieve a circuit connection function. For example, patent application No. CN209134273U discloses a connection structure for a voice coil motor, which includes an injection-molded part and a flexible circuit board (FPC). The injection molding has a plurality of in proper order encircle to connect the formation the lateral wall of cavity, one of them seted up on the lateral wall link up in the location chamber of cavity, flexible circuit board FPC with have the location chamber the lateral wall laminating, FPC subsides dress or the integration of winding have IC and coil to reach the effect that the circuit switched on.

Also, as disclosed in the patent application with publication number CN108989511A, a base and a voice coil motor having electronic components are disclosed, wherein the electronic components are integrated on a vertical surface of plastic, and a subsequently mounted coil is also mounted on the vertical surface of plastic, and the subsequent mounting needs to be performed by SMT (surface Mount technology), and since the surface mounted by SMT mounting requires that one side of the surface is open, the coil is difficult to wind or Mount, and the requirement for the position design of the coil is very high. Therefore, it is difficult to automate the Integrated Circuit (IC) or coil on the vertical plane, and complicated manual operations are required, which results in low efficiency and poor quality stability. When the IC or the coil is integrated on the base located on the horizontal plane, only one IC or coil can be assembled, and the automation efficiency of the assembly is very low. And SMT pastes the dress equipment on the present market all is that a processing base, does not have the batch nature to handle.

Above problem concentrate on when taking place in current voice coil motor manufacturer production voice coil motor, need purchase spare part outward, again to components and parts such as flexible circuit board/shell fragment and carry out the location equipment, location, processing and assembly process are complicated, and operating space is limited, causes the bad of spare part easily, and then arouses that overall cost is too high. Meanwhile, when the purchased parts are regenerated, the combination condition is not considered, and the problem of combination space design is ignored, so that some installation positions need to be reserved when the voice coil motor is designed, space waste is caused, and the structure of the product cannot be compact and miniaturized. And because the original coil generally needs to be integrated with a metal circuit in the base on an independent FPC, the FPC is thin in thickness, fragile and high in cost, the difficulty is high when a coil needs to be wound or mounted on the FPC, badness is easily caused, the number of turns of the wound coil and the thickness of the coil can be influenced by the thickness of the FPC, the size of the current of the coil is further influenced, and the loss of the circuit is increased. In addition, the coil is wound or attached on an independent FPC, and since the FPC is flexible, when the electronic device falls, the voice coil motor having the coil fixed to the FPC easily fails as a whole due to weak integration strength of itself.

Therefore, it is necessary to provide a new base and a new vcm having a coil and a manufacturing method thereof to overcome the above-mentioned drawbacks.

Hereinafter, the base 100, the vcm 1000 having the base 100 and the manufacturing method thereof according to the present invention will be described with reference to fig. 1 to 13.

The present invention relates to a Voice Coil Motor (VCM) 1000, which is an important component for focusing and anti-shake of a camera. The main principle of the voice coil motor is that in a permanent magnetic field, the extension position of the spring piece is controlled by changing the direct current of a coil in the motor, so that the lens is driven to move up and down. The mobile phone camera widely uses the voice coil motor to realize the automatic focusing function, and the position of the lens can be adjusted through the voice coil motor to present clear images. The voice coil motor 1000 includes an outer casing 101, a magnetic element 104, a lens 103, a holder 106 for carrying the lens 103, and a base 100 integrated with a coil 5 interacting with the magnetic element 104. The magnetic element 104, the lens 103 and the bracket 106 carrying the lens 103 are referred to as a movable module. In the present invention, the coil 5 is integrated with the base 100, and thus the movable module and the coil can move in various directions, so as to realize various functions of the voice coil motor 1000.

The closed-loop voice coil motor is internally provided with a bearing Hall sensor in a drive IC, wherein the sensor belongs to a position sensor and can measure the magnetic flux (Gaussian value) in a magnetic field so as to judge the position of an object; the closed-loop voice coil motor utilizes the sensor to determine the magnitude of the current required to be applied, which is equivalent to the closed-loop control of more negative feedback, so that the lens can move more accurately each time, the times of the lens moving back and forth can be reduced, and the focusing speed is improved. The linearity of the open-loop voice coil motor depends on the change of the magnetic thrust of the coil and the automatic focusing magnetic element on different strokes and the change caused by the nonlinearity of the elastic sheet; the closed-loop voice coil motor is completely dependent on the configuration of the Hall sensor and the Hall magnetic element and the linearity compensation of the drive IC.
