Embodiment 1

[0041] A brand-new VCM motor coil straight-wound base structure, including a base 7 formed by injection molding, and four straight-wound columns 75 corresponding to the four permanent magnets 5 in the VCM motor are arranged on the base 7 near the four corners. The coils 71 connected to each other are respectively arranged on the straight winding columns 75, and the copper wires connected between two adjacent coils 71 are in contact with the contacts 72 preset on the base 7 and located on both sides of the coils 71 respectively. The copper wires between the coils 71 are fixed by the fixed ribs 74 fixedly arranged on the base 7 .

[0042] The working principle of this embodiment is not substantially different from the working principle of the existing VCM motor, only the installation method of the base and the coil is changed, so that the technical effect can be changed through the change of the structure. In this embodiment, the coil 71 is positioned and installed by using the ...

Embodiment 2

[0046] On the basis of Example 1, further in conjunction with the attached Figure 4 In the structure shown, the fixed ribs 74 are arranged in parallel and in pairs, and are located in the middle of two adjacent coils 71 . The above-mentioned structure is used to respectively fix two adjacent coils, and at the same time, it is beneficial to the subsequent coil division. The two free ends of the divided copper wires are fixed by the fixing ribs 74 without any influence on the coils. , and is not affected by external force. There is no fixed sequence between the segmentation process and the welding process, which is more convenient to operate. The contact 72 always corresponds to the position of the copper wire, which greatly reduces the difficulty of welding, improves the accuracy of welding and one-time sexual success rate.

Embodiment 3

[0048] On the basis of the structure of Embodiment 1 or 2, in order to solve the problem that there are two free copper wire ends fixed when the integrated coil 71 is installed, the integrated coil 71 after installation is relative to the base 7. The positions of the copper wires between the two adjacent coils 71 are determined, so that during subsequent welding, the positions of the copper wires and the contacts 72 are determined, reducing the difficulty of welding, such as Figure 5 As shown: a terminal 76 for fixing the free ends of the two copper wires of the coil 71 is arranged between any pair of fixed ribs 74 arranged in parallel. There is a gap in between. Since the four coils 71 are an integral structure connected to each other before installation, the two coils 71 at the head and tail respectively have a free copper wire end. In order to further facilitate installation and welding, a terminal post 76 is provided on the base 7 for winding Fix the two free copper wire...

Abstract

The invention discloses a brand-new VCM motor coil straight winding base structure. The structure comprises a base formed through injection molding. Four straight winding columns corresponding to fourpermanent magnets in a VCM motor are arranged at positions, close to four corners, of the base. The four straight winding columns are provided with coils which are connected with one another, copperwires connected between every two adjacent coils make contact with contacts which are arranged on the base in advance and located on two sides of the coils respectively, and the copper wires between every two adjacent coils are fixed through fixing ribs fixedly arranged on the base. Problems of tedious assembling efficiency, high labor cost, low efficiency, low reliability and the like of the VCMmotor which always puzzles the industry are solved.

Description

technical field [0001] The invention relates to the field of VCM motors, in particular to a VCM motor base, and in particular to a brand-new VCM motor coil directly wound base structure. Background technique [0002] The VCM motor is an important part for camera focusing and anti-shake. Because the working principle is similar to that of a speaker, it is also named as a voice coil motor in the industry. The main principle of the voice coil motor is to control the stretching position of the spring leaf by changing the DC current of the inner coil of the motor in a permanent magnetic field, thereby driving the up and down movement. Mobile phone cameras widely use VCM to realize the auto-focus function, through which the position of the lens can be adjusted to present a clear image. [0003] Although the existing voice coil motors have different product structures or names based on different production designers, they generally include the following components: the outer shel...
