An automatic assembly mechanism for thin-walled devices

Abstract

The invention relates to the technical field of automatic assembly, and in particular, discloses an automatic assembly mechanism of a thin-wall device. The mechanism comprises a thin-wall piece feeding mechanism, an assembly body feeding mechanism, a thin-wall piece clamping and assembly mechanism and a driving mechanism, wherein the driving mechanism is used for driving the thin-wall piece clamping and assembly mechanism to operate between the thin-wall piece feeding mechanism and the assembly body feeding mechanism. The automatic assembly mechanism of the thin-wall device uses a porous sucker for combining with an air pump to grab thin-wall pieces, wherein each small hole can provide the suction; gaps between the adjacent holes achieve the effect of supporting the thin-wall pieces; as the porous structure guarantees uniform air pressure suffered by the thin-wall pieces during clamping, when the thin-wall pieces are clamped, the deformation of exceeding requirements cannot be generated; and the mechanism guarantees repeated positioning errors of the porous sucker through a three-point laser positioning method.

Description

technical field [0001] The invention relates to the technical field of automatic assembly, in particular to an automatic assembly mechanism for thin-walled devices. Background technique [0002] Voice coil motor, referred to as VCM (Voice Coil Motor), is a high-tech precision product that has emerged in recent years. With its excellent characteristics and small size, it is widely used in high-end mobile phone camera equipment that requires high pixel, high image quality and high precision. Among them, it is the trend of mobile phone camera development in the future. At present, the assembly of VCM is mainly manual, which is not only time-consuming and labor-intensive, but also easily causes accuracy errors. The above-mentioned disadvantages can be avoided by using automatic assembly. However, the thin-walled parts among them have become the difficulty of automatic assembly due to the reasons such as thin and easy to deform, difficult to handle and position. For small thin-w...

Problems solved by technology

At present, the assembly of VCM is mainly manual, which is not only time-consuming and labor-intensive, but also easily causes accuracy errors. Automatic assembly can avoid the above disadvantages

However, the thin-walled parts among them have become the difficulty of automatic assembly due to the reasons such as thin and easy to deform, difficult to handle and position. For small thin-walled parts, there is no effective clamping and clamping method at present. Conventional manipulator clamping method is adopted. It is easy to cause deformation of the reed as a thin-walled part. In addition, thin-walled parts tend to shift during assembly. At present, there is no effective way to prevent the displacement of the reed during assembly.

Based on the above two reasons, it is difficult to realize automatic assembly of voice coil motors. Therefore, it is necessary to design an assembly mechanism suitable for automatic assembly of thin-walled parts to solve the problems faced by the assembly of voice coil motors in the prior art. some deficiencies
