Description

Technical Field

[0001] The utility model relates to the technical field of microphone production equipment, in particular to a polarization device for 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 polarization device 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 polarization device for microphone components, comprising a frame, on which a polarization device is mounted, the polarization device comprising a horizontally arranged turntable, a plurality of workstations being arranged at equal intervals around the turntable, each of the workstations being provided with a material placement tool, the material placement tool being provided with a plurality of material placement slots; a feeding device connected to the material placement tool being provided at one of the workstations, a polarization electrode assembly being provided at a workstation downstream of the feeding device, the polarization electrode assembly comprising polarization electrodes corresponding to the material placement slots, and a unloading assembly being provided at a workstation downstream of the polarization electrode assembly.

[0006] There are two polarized electrode assemblies, and the two polarized electrode assemblies are respectively arranged at two adjacent workstations.

[0007] Wherein, the polarized electrode assembly includes polarized electrodes that can slide in the up and down and front and back directions under the drive of a power device.

[0008] Among them, the polarization electrode is installed on the electrode mounting plate, and the electrode mounting plate is driven by the electrode transverse movement cylinder to slide and be installed on the electrode lifting mounting plate. The electrode lifting mounting plate is connected to the piston rod of the electrode lifting cylinder, and the electrode lifting cylinder is installed on the electrode assembly base.

[0009] Among them, the material placement groove includes a material placement part and a discharge claw insertion part that are communicated with each other. The material placement part is located at the edge position of the material placement tooling and is open.

[0010] Among them, the discharge assembly includes a discharge claw that can slide in the up and down and front and back directions under the drive of a power device. The number of discharge claws is the same as the number of material placement grooves.

[0011] Among them, the discharge claw is installed on a discharge claw mounting plate. The discharge claw mounting plate is driven by a discharge transverse translation cylinder to be slidably installed on a discharge claw lifting mounting plate. The discharge claw lifting mounting plate is connected to the piston rod of a discharge claw lifting cylinder. The discharge claw lifting cylinder is installed on a discharge assembly base.

[0012] Among them, the feeding device includes a linear feeder that is connected to the material placement tooling. The discharge end of the linear feeder is provided with linear feeding channels that are the same in number as and correspondingly connected to the material placement grooves. The feeding end of the linear feeder is connected to a vibrating bowl.

[0013] Among them, a linear discharger that is connected to the material placement tooling is installed at the station where the discharge assembly is located.

[0014] Among them, the machine frame includes a framework. The top of the framework is provided with a mounting platform. The polarization device is installed on the mounting platform. The bottom of the framework is installed with adjusting feet and universal wheels.

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

[0016] Since the polarization device for the microphone component of the present utility model includes a frame, a polarization device is installed on the frame. The polarization device includes a horizontally arranged turntable, and a plurality of workstations are equidistantly arranged on the periphery of the turntable. A material placement tooling is arranged at each workstation, and a plurality of material placement slots are arranged on the material placement tooling; a feeding device connected to the material placement tooling is arranged at one of the workstations, a polarization electrode assembly is arranged at the workstation downstream of the feeding device, the polarization electrode assembly includes a polarization electrode corresponding to the material placement slot, and a discharging assembly is arranged at the workstation downstream of the polarization electrode assembly. In the present utility model, the material is sent into the material placement slot of the material placement tooling through the feeding device, and one material is placed in one material placement slot. Then the turntable rotates once to transfer the material placement tooling with the material to the next workstation. The polarization electrode in the electrode polarization assembly at the next workstation polarizes the material in the material placement slot. Since the polarization electrode corresponds to the material one by one during polarization, it is ensured that the polarization electric field received by each material is the same, that is, the polarization voltage received by each material is consistent. Therefore, the polarization consistency of each material is good, and further the consistency of the microphone is good and the qualified rate is high.

[0017] In summary, the polarization device for the microphone component of the present utility model solves the technical problems such as poor polarization consistency in the prior art. The materials polarized by the polarization device for the microphone component of the present utility model have good consistency, and further the produced microphones have good consistency and high qualified 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 As shown, a polarization device for a microphone component includes a frame 10 and a polarization device 20 installed on the frame 10.

[0025] like Figure 1 As shown, the rack 10 includes a frame 12 with a mounting platform 18 at its top. Adjustable feet 14 and universal wheels 16 are mounted at its bottom. The adjustable feet 14 adjust the height and balance of the polarization device when it is fixed, while the universal wheels 16 facilitate transport of the polarization device. The frame 12 houses the controller for the polarization device (not shown). A vertical pole is mounted on the mounting platform 18, and an operating screen 40 is mounted on the pole. The operating screen 40 is in communication with the controller and is used by workers to control the operation of the polarization device.

[0026] like Figure 1 and Figure 2As commonly shown, the polarization device 20 is installed on the installation platform 18. The polarization device 20 includes a horizontally arranged turntable 21, and a plurality of workstations are equidistantly arranged on the circumferential side of the turntable 21. A material placement tooling 22 is arranged at each workstation. In this embodiment, it is preferably that a total of eight workstations are arranged on the circumferential side of the turntable 21, that is, eight material placement toolings 22 are equidistantly installed on the circumferential side of the turntable 21, and these eight material placement toolings 22 rotate with the rotation of the turntable 21. In this embodiment, it is preferably that the turntable 21 is driven by a servo motor (not shown in the figure) to rotate counterclockwise. Each time the turntable 21 rotates through an angle of 45°, the material placement tooling 22 at the previous workstation can be rotated to the next workstation, and its rotation interval time is set according to the polarization required time of the material, which can ensure the polarization effect of the material. For the convenience of description, here the eight workstations are respectively named as the first workstation 260, the second workstation 261, the third workstation 262, the fourth workstation 263, the fifth workstation 264, the sixth workstation 265, the seventh workstation 266, and the eighth workstation 267 in the counterclockwise direction, where: the first workstation 260 is the feeding workstation, and a feeding device connected to the material placement tooling 22 is installed here; the second workstation 261 and the third workstation 262 are the polarization workstations, and polarization electrode assemblies are installed at these two workstations, that is, polarization electrode assemblies are arranged at the workstations downstream of the feeding device; the seventh workstation 266 is the discharging workstation, and a discharging assembly 28 is installed at this workstation, that is, a discharging assembly 28 is arranged at the workstation downstream of the polarization electrode assembly; the remaining fourth workstation 263, fifth workstation 264, sixth workstation 265, and eighth workstation 267 are buffer standby workstations.

[0027] As Figure 1 , Figure 2 and Figure 3As shown together, the material placement tooling 22 is a block structure, on which there are multiple material placement slots 220. In this embodiment, it is preferred that there are four material placement slots 220, but it is not limited to four. The specific number can be set according to the sizes of the turntable 21 and the material placement tooling 22. Four is only an example in this embodiment. In this embodiment, the material placement slots 220 are arranged at the outer edge of the upper surface of the material placement tooling 22, including a material placement portion 2200 located at the edge side of the material placement tooling 22. The material placement portion 2200 is open towards the edge side of the material placement tooling 22. The material placement portion 2200 communicates with a discharge claw insertion portion 2202 towards the inner side of the material placement tooling 22. The material placement portion 2200 is a U-shaped structure, and the discharge claw insertion portion 2202 is a slightly narrower square shape. The material is directly sent into the material placement portion 2200 by the feeding device, and is polarized at the second station 261 and the third station 262 as the turntable 21 rotates. When it rotates to the seventh station 266 after polarization, the discharge claw 282 of the discharge assembly 28 picks out the material from the material placement portion 2200, thus completing the discharging. The empty material placement tooling 22 then rotates to the first station 260 to receive the material conveyed by the feeding device, and so on.

[0028] As Figure 1 and Figure 2 As shown together, the feeding device is installed at the first station 260, and includes a linear feeder 25 and a vibrating bowl 30. The discharge end of the linear feeder 25 is provided with a linear feeding channel 250 that is connected to the material placement slot 220. The number of linear feeding channels 250 is the same as the number of material placement slots 220, and there are four in total, that is, the linear feeder 25 is connected to the material placement tooling 22. The feeding end of the linear feeder 25 is connected to the vibrating bowl 30. The material is vibrated and conveyed from the vibrating bowl 30 onto the linear feeder 25, and passes through the four linear feeding channels 250 one by one in line and is sent into the material placement slot 220. After there is material in all four material placement slots 220, the linear feeder 25 stops working. The turntable 21 rotates 45°, and this material placement tooling 22 rotates to the second station 261. The empty material placement tooling 22 at the original eighth station 267 rotates to the first station 260. The linear feeder 25 starts working again to fill the material placement slots 220 on this material placement tooling 22, and so on to complete the feeding work.

[0029] As Figure 1 and Figure 2As shown together, preferably two polarization electrode assemblies are provided in this embodiment, which are respectively defined as a first polarization electrode assembly 23 and a second polarization electrode assembly 24. The first polarization electrode assembly 23 is installed at the second station 261, and the second polarization electrode assembly 24 is installed at the third station 262. The first polarization electrode assembly 23 and the second polarization electrode assembly 24 have the same structure and work simultaneously. Two polarization electrode assemblies are provided in this embodiment to improve the polarization efficiency. If a polarization electrode assembly is provided only at one station, the polarization time of the material is X minutes, then the rotation interval time of the turntable 21 needs to be X minutes; if a polarization electrode assembly is provided at each of the two stations, the residence time of the material at each station can be halved, and the rotation interval time of the turntable 21 only needs to be X / 2, thus doubling the working efficiency.

[0030] As Figure 1 and Figure 2 As shown together, since the first polarization electrode assembly 23 and the second polarization electrode assembly 24 have the same structure, the structure of the polarization electrode assembly will be described in detail below only taking the second polarization electrode assembly 24 as an example:

[0031] The second polarization electrode assembly 24 includes an electrode assembly base 247 fixed on the mounting platform 18. An electrode lifting cylinder 245 is vertically installed on the electrode assembly base 247. A horizontally arranged electrode lifting mounting plate 243 is connected to the piston rod of the electrode lifting cylinder 245. An electrode transverse movement cylinder 242 is horizontally installed on the electrode lifting mounting plate 243. The piston rod of the electrode transverse movement cylinder 242 is connected to an electrode mounting plate 241. An electrode guide rail 244 is fixed on the electrode lifting mounting plate 243. The electrode mounting plate 241 is fixed on the slider of the electrode guide rail 244. An electrode limiting member 246 is installed at each end of the electrode lifting mounting plate 243. The two electrode limiting members 246 are arranged oppositely to limit the moving distance of the electrode mounting plate 241. A plurality of polarization electrodes 240 are vertically installed on the lower side of the electrode mounting plate 241. In this embodiment, four polarization electrodes 240 are provided, which is the same as the number of the material placement grooves 220. The four polarization electrodes 240 respectively correspond to the four material placement grooves 220. When the material placement tooling 22 carrying the material rotates to the third working station 262 (the working process at the second working station 261 is the same, and only the working process of the polarization electrode assembly is elaborated in detail here taking the third working station 262 as an example), the piston rod of the electrode transverse movement cylinder 242 extends to drive the electrode mounting plate 241 to slide forward (the direction where the material placement tooling 22 is located), and sends the polarization electrode 240 directly above the material placement groove 220. Then, the piston rod of the electrode lifting cylinder 245 retracts to drive the polarization electrode 240 to slide downward, approaching the material in the material placement groove 220, and polarize the material. After reaching the set polarization time, the piston rod of the electrode lifting cylinder 245 extends to drive the polarization electrode 240 to slide upward. Then, the piston rod of the electrode transverse movement cylinder 242 retracts to drive the electrode mounting plate 241 to slide backward and reset. Thus, the polarization electrode 240 can slide in the vertical and horizontal directions under the drive of the power device to complete the polarization of the material. After the polarization is completed, the turntable 21 rotates to send the polarized material to the next working station, and so on.

[0032] Such as Figure 1 , Figure 2 and Figure 3As shown together, the unloading assembly 28 is installed at the seventh station 266, and includes an unloading assembly base 285 fixed on the installation platform 18. Vertically installed on the unloading assembly base 285 is an unloading claw lifting cylinder (not shown in the figure). Connected to the piston rod of the unloading claw lifting cylinder is a horizontally arranged unloading claw lifting mounting plate 283. Horizontally installed on the unloading claw lifting mounting plate 283 is an unloading transverse cylinder 280. The piston rod of the unloading transverse cylinder 280 is connected to an unloading claw mounting plate 281. Fixed on the unloading claw lifting mounting plate 283 is an unloading claw guide rail 284. The unloading claw mounting plate 281 is fixed on the slider of the unloading claw guide rail 284. At both ends of the unloading claw lifting mounting plate 283, there is an unloading claw limit member 286 installed respectively. The two unloading claw limit members 286 are arranged oppositely to limit the moving distance of the unloading claw mounting plate 281. Installed on the lower side of the unloading claw mounting plate 281 are a plurality of unloading claws 282. In this embodiment, there are four unloading claws 282, which is the same as the number of the material placement grooves 220. The four unloading claws 282 respectively correspond to the four material placement grooves 220. Driven by the two power devices of the unloading claw lifting cylinder and the unloading transverse cylinder 280, the unloading claws 282 can slide in the vertical and front-back directions. Since the installation method and working process of the power device of the unloading assembly 28 are basically the same as those of the power device of the polarization electrode assembly, the working process of the unloading assembly 28 will not be elaborated here. The difference between the two is only that after the unloading claws 282 descend, they will insert into the unloading claw insertion part 2202 of the material placement groove 220, and then the piston rod of the unloading transverse cylinder 280 retracts, driving the unloading claws 282 to slide backward, so as to pick out the material from the material placement groove 220 and complete the unloading.

[0033] As Figure 1 , Figure 2 and Figure 3 As shown together, a linear discharger 27 is also installed at the seventh station 266. The linear discharger 27 is connected to the material placement tooling 22. The material picked out from the material placement groove 220 by the unloading claws 282 will fall onto the linear discharger 27 and be vibrated and conveyed into a material collection tray (not shown in the figure), and then transferred to the next assembly process of the microphone.

[0034] In summary, the materials polarized by the polarization equipment for the microphone component of the present invention have good consistency, thus making the produced microphones have good consistency and high qualification rate.

[0035] The present invention is not limited to the above specific embodiments. Those of ordinary skill in the art starting from the above concepts and making various transformations without creative labor fall within the protection scope of the present invention.
