Description

Technical Field

[0001] The utility model relates to the technical field of microphone production equipment, in particular to a polarizing machine for electret microphone components. Background Art

[0002] An electret microphone includes a housing, within which are mounted components such as a diaphragm, a back plate, and a copper ring and insulating ring that form a three-component assembly with the back plate. During the microphone production process, the diaphragm, back plate, or three-component assembly must be polarized to impart polarity, thereby forming a variable capacitor. The current method for polarizing the diaphragm, back plate, or three-component assembly is to first fill a disk with the material to be polarized, and then place it in a polarizing electric field for polarization. This polarization method results in different positions of the materials in the disk, and thus in different positions in the polarizing electric field. As a result, the polarization voltages applied during polarization are also different, resulting in poor consistency in the polarized materials. This, in turn, leads to inconsistent performance, poor consistency, and a low pass rate for the microphones produced. Utility Model Content

[0003] In view of the above defects, the purpose of the present invention is to provide a polarizing machine for microphone components, which can polarize materials with good consistency, thereby making the produced microphones have good consistency and high pass rate.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A polarizing machine for microphone components comprises a frame on which a plurality of polarizing lines are mounted. The polarizing lines comprise a vibration plate, a conveyor belt, and a material receiving plate sequentially arranged along the direction of material movement. A polarizing electric field capable of polarizing the material on the conveyor belt is arranged above the conveyor belt.

[0006] Wherein, a first material channel is connected between the vibration plate and the conveyor belt, and the width of the first material channel is only enough for a single material to pass through.

[0007] Wherein, a second material channel is connected between the conveyor belt and the receiving tray.

[0008] Wherein, a baffle plate for guiding the material to the second material channel is provided on the conveyor belt at the position connected with the second material channel.

[0009] Wherein, two polarization lines are arranged side by side, and the two polarization lines share one receiving tray.

[0010] Wherein, the polarization electric field includes a medium-voltage electrode arranged above the conveyor belt, and a high-voltage electrode arranged above the medium-voltage electrode.

[0011] The medium voltage electrode is a horizontally arranged long ring structure, and the high voltage electrode is arranged directly above the ring center of the medium voltage electrode and corresponds to the conveyor belt.

[0012] Among them, two lower electrode pillars are provided on each side of the two conveyor belts, and the two medium-voltage electrodes are respectively arranged on the lower electrode pillars on both sides of the corresponding conveyor belts. Two upper electrode pillars are provided on the two sides away from each other, and the two opposite upper electrode pillars are connected with electrode beams, and the two high-voltage electrodes are fixed on the two electrode beams.

[0013] The rack includes a cabinet, a mounting platform is provided above the cabinet, the polarization line is installed on the mounting platform, and an operation screen is installed on one side of the mounting platform.

[0014] Wherein, the bottom of the cabinet is installed with adjusting feet and universal wheels.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] Since the polarization machine for microphone components of the present invention includes a frame, a plurality of polarization lines are installed on the frame, and the polarization lines include a vibration plate, a conveyor belt and a receiving plate arranged in sequence along the direction of material movement; a polarization electric field capable of polarizing the material on the conveyor belt is arranged above the conveyor belt. In the present invention, the material is fed by the vibration plate, and the vibration plate will send the material to the conveyor belt one by one, so that the material is arranged in a row on the conveyor belt and enters the polarization electric field. As the conveyor belt moves, the material moves from one end of the polarization electric field to the other end, and polarization is completed during this movement. Since the position of each material when passing through the polarization electric field is the same, the voltage it receives in the polarization electric field is consistent, so the polarization consistency of each material is good, which makes the microphone consistent and the qualified rate high.

[0017] In summary, the polarization machine for microphone components of the present invention solves technical problems such as poor polarization consistency of microphone components in the prior art. The material polarized by the polarization machine for microphone components of the present invention has good consistency, thereby making the produced microphones have good consistency and a high pass rate.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The directions mentioned in this specification are based on the directions shown in the drawings and only represent relative positions, not absolute positions.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown together, a polarizer for a microphone component includes a frame 10 and a plurality of polarization lines 20 installed on the frame 10.

[0025] like Figure 1 and Figure 3 As shown, the frame 10 includes a cabinet 16, with a mounting platform 18 positioned above the cabinet 16. Adjustable feet 12 and universal wheels 14 are mounted at the four corners of the bottom of the cabinet 16. The adjustable feet 12 adjust the height and balance of the polarization machine when it is stationary, while the universal wheels 14 facilitate transport of the polarization machine. The cabinet 16 can be used to house the polarization machine's controller (not shown). A vertical pole is mounted on one side of the mounting platform 18, on which an operating screen 30 is mounted. The operating screen 30 is in communication with the controller and is used by workers to control the operation of the polarization machine.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the polarization line 20 is mounted on the mounting platform 18. The polarization line 20 comprises a vibrating plate 21, a first material channel 220, a conveyor belt 23, a second material channel 222, and a receiving tray 26, arranged sequentially along the material's travel direction. It also includes a polarization electric field 24, positioned above the conveyor belt 23, capable of polarizing the material on the conveyor belt 23. The materials involved in this embodiment refer to the microphone's diaphragm, back plate, or three components. The specific components that require polarization are determined by the microphone's specifications and production process. The polarization machine of this utility model is applicable to all materials.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown in the figure, the vibration plate 21 is used for feeding. The vibration plate 21 can send the materials one by one to the first material channel 220 through vibration. The first material channel 220 is connected between the vibration plate 21 and the conveyor belt 23. The width of the first material channel 220 is only enough for a single material to pass through, so the materials are lined up one by one and conveyed to the conveyor belt 23. The conveyor belt 23 is driven by the conveyor belt motor 28, thereby driving the materials on the conveyor belt 23 to move from one end of the polarization electric field 24 to the other end. By adjusting the rotation speed of the conveyor belt motor 28, the running speed of the conveyor belt 23 is determined so that the time for the materials on the conveyor belt 23 to move from one end of the polarization electric field 24 to the other end meets the polarization time, thereby completing the polarization of the materials. A second material channel 222 is positioned side by side at the end of the conveyor belt 23, connecting the conveyor belt 23 with a receiving tray 26. A material baffle 224 is positioned at an angle where the conveyor belt 23 meets the second material channel 222. As the conveyor belt 23 advances, the material is automatically transferred from the conveyor belt 23 to the second material channel 222, blocked and guided by the material baffle 224. The end of the second material channel 222 is connected to a receiving tray 26, where the polarized material is ultimately conveyed to the receiving tray 26 and collected for use in microphone assembly.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown together, in this embodiment, two polarization lines 20 are preferably arranged side by side, and these two polarization lines 20 are symmetrically arranged relative to the long axis of the mounting platform 18. The two polarization lines 20 share a receiving tray 26, that is, the ends of the second material channels 222 of the two polarization lines 20 are connected to the same receiving tray 26, and the materials polarized by the two polarization lines 20 are collected by a receiving tray 26.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown together, the polarization electric field 24 includes a medium-voltage electrode 242 disposed above the conveyor belt 23, and a high-voltage electrode 240 disposed above the medium-voltage electrode 242. In this embodiment, the medium-voltage electrode 242 preferably has a horizontally arranged long ring structure, and the high-voltage electrode 240 is disposed directly above the center of the medium-voltage electrode 242, which is also directly above the conveyor belt 23, corresponding to the conveyor belt 23. The high-voltage electrode 240 acts as an accelerating electric field, causing charges to accumulate on the material and completing the polarization of the material, while the medium-voltage electrode 242 acts to fine-tune the electric field.

[0030] like Figure 1 、 Figure 2 and Figure 3As shown together, in this embodiment, two lower electrode pillars 246 are vertically provided on both sides of the two conveyor belts 23, and two medium-voltage electrodes 242 are respectively arranged on the lower electrode pillars 246 on both sides of the corresponding conveyor belts 23. Two upper electrode pillars 244 are respectively provided on the two side edges away from each other of the two medium-voltage electrodes 242, and the two opposite upper electrode pillars 244 are connected to the electrode beams 248, and the two ends of the two high-voltage electrodes 240 are respectively fixed on the two upper electrode beams 248.

[0031] In summary, the electric field of the material of the polarizer used for the microphone component of the present invention during polarization is consistent, and the polarized material has good consistency, thereby ensuring good consistency, stable performance, and high pass rate of the microphone.

[0032] The present invention is not limited to the above-mentioned specific implementation methods. Various modifications made by ordinary technicians in this field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
