Problems solved by technology

Connect and fix the upper end of the iron core with the pressing block, and flatten the joint to prevent the rotation of the iron core; set the pressing block to drive the pressing block through the second driving mechanism to drive the iron core, and set the second on both sides of the center of the pressing block. The guide shaft is used to ensure that the force and the direction of movement of the iron core are vertically downward during the downward movement driven by the second drive mechanism, which solves the problem of the coaxiality of the iron core and the pressing knife, and prevents the iron core and the pressing knife from The slight deviation of the pressure knife or the iron core will cause wear and tear, which increases its service life and reduces the probability of magnetism being stuck

Embodiment 1

[0064] Such as Figure 1-5 As shown, a high-precision magnet loading device includes a workbench 11, a magnet press-in mechanism 2 installed on the workbench 11, a magnet feeding mechanism 3 arranged on the workbench 11, and a jig arranged below the workbench 11. 41.

[0065] A notch is provided on the workbench 11 to facilitate the replacement of the jig 41 .

[0066] The magnet press-in mechanism 2 includes a gantry frame 21, which is arranged above the center position of the workbench 11, on the gantry frame 21 is provided with a pressing knife assembly that moves up and down intermittently, and the pressing knife assembly includes a vertically arranged and The iron core 233 for absorbing the magnet and the pressure sleeve 224 socketed with the iron core 233, the pressure sleeve 224 includes four pressure strips 2241 evenly distributed on the side wall of the iron core 233 and not attracted to the magnet, and the connection There are four beading bars 2241 and a beading b...

Embodiment 2

[0087] Compared with Embodiment 1, this embodiment differs in the pressing knife assembly, the second driving mechanism and the working method.

[0088] In Embodiment 1, the iron core 233 is installed on the piston rod of the second cylinder 231 through the connector 232, so the rotation of the piston rod will directly cause the iron core 233 to rotate, and it is difficult for the magnet press knife and the guide iron core to ensure both The coaxiality between them will easily cause the wear of the pressing knife or the iron core, reduce the life of the part, and at the same time, it is prone to the phenomenon of magnetism. In order to solve these problems, we designed a stable pressure knife mechanism that can simultaneously ensure the coaxiality of the iron core and the pressure and prevent the iron core from rotating at the working position.

[0089] Such as Figure 12 ~ Figure 13 As shown, the stabilizing knife pressing mechanism includes a lower beam 25 , a second drive ...

Abstract

The invention relates to a stable pressing cutter mechanism, a high-precision magnet loading device and an operating method thereof. The stable pressing cutter mechanism comprises a lower cross beam,a second driving mechanism, a pressing cutter assembly, an iron core and an elastic recovery mechanism, wherein the elastic recovery mechanism comprises second guide shafts and a compression spring, the two second guide shafts are provided with a pressing block in a threaded manner; the upper end of the iron core is fixed on the pressing block after passing through the pressing cutter assembly; and the second driving mechanism is positioned above the pressing block, and the second driving mechanism downwardly drives the pressing block and the iron core to move downwards. According to the stable pressing cutter mechanism, the high-precision magnet loading device and the operating method thereof, the upper end of the iron core is connected and fixed to the pressing block, the joint is flatlymilled so as to prevent rotation of the iron core; the pressing block is arranged and driven by means of the second driving mechanism so as to drive the iron core, the second guide shafts are arranged on two sides of the center of the pressing block to ensure that stress and motion directions of the iron core are vertically downward in the downward moving process driven by means of the second driving mechanism, the coaxiality problem of the iron core and the pressing cutter is solved, the service life of the iron core and the pressing cutter is prolonged, and the probability of occurrence ofthe magnet jamming phenomenon is reduced.

Description

technical field [0001] The invention belongs to the field of VCM automation, and in particular relates to a stable pressing mechanism, a high-precision magnet loading device using the mechanism and a working method thereof. Background technique [0002] VCM (Voice Coil Motor) linear motor, also known as voice coil motor, is a kind of motor. Its main principle 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. In order to drive the up and down movement, for example, in the camera of a smartphone, a VCM linear motor is needed, which can adjust the position of the lens (Lens) to change the focal length, so that the camera can show the clearest state. [0003] The VCM linear motor in the prior art mainly includes a carrier, a coil, a base, a spring piece, and a spacer, and four magnets are respectively embedded in the base. 4 magnets are loaded into the inner side of the base to form ...
