Description

Technical Field

[0001] This utility model belongs to the field of microphone assembly technology, specifically relating to a microphone diaphragm pad three-piece assembly machine. Background Technology

[0002] An electret microphone consists of two parts: acoustic-to-electric conversion and impedance transformation. The key component of the acoustic-to-electric conversion is the electret diaphragm. It is an extremely thin plastic diaphragm with a thin metal film evaporated onto one side. After being electreted by a high-voltage electric field, opposite charges are deposited on both sides. The metal-coated side of the diaphragm faces outwards and is connected to the metal casing. An electret microphone uses a field-effect transistor for pre-amplification; therefore, an electret microphone requires a certain bias voltage during normal operation, which is generally no greater than 10V.

[0003] However, most current microphone assembly equipment suffers from low automation and excessive reliance on manual labor, resulting in low assembly efficiency and inconsistent product quality. Furthermore, excessive manual labor also increases production costs. Therefore, there is an urgent need for a microphone diaphragm and gasket three-piece assembly machine to solve these problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a microphone diaphragm pad three-piece assembly machine, so as to solve the problem mentioned in the background art that most assembly devices in the current microphone assembly process have low automation and rely too much on manual labor, resulting in low assembly efficiency and inconsistent product quality; in addition, excessive manual work also leads to the problem of increased production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microphone diaphragm pad three-piece assembly machine, comprising a support frame, a conveyor belt, and a feeding structure. Three cylinders are fixedly connected to the top of the support frame, and the conveyor belt is located at the bottom of the cylinders. The feeding structure has three components, each including a feeding hopper. A fixed seat is fixedly connected to the front of the feeding hopper, and a bracket is fixedly connected to the right side of the fixed seat. An electric push rod is fixedly connected to the outer wall of the bracket, and a push plate is fixedly connected to the electric push rod. A mounting frame is fixedly connected to the left side of the fixed seat. Hinge supports are fixedly connected to both the front and rear ends of the bottom of the mounting frame. Hinge supports are rotatably connected to hinge supports, and a baffle is fixedly connected to the outer wall of hinge supports.

[0006] Preferably, the bottom of the feed hopper is fixedly connected to two support legs.

[0007] Preferably, the feed hopper consists of a rear feed hopper and a front feed channel, and the width of the groove of the feed channel is the same as the size of the diaphragm.

[0008] Preferably, a baffle is provided on the front side of the fixing seat, a push plate is slidably connected to the right side of the fixing seat, and sliding grooves are provided on the left and rear sides of the fixing seat.

[0009] Preferably, the left and right sides of the first hinge support are rotatably connected to a rotating shaft, and the rotating shaft is rotatably connected to the left and right ends of the second hinge support.

[0010] Preferably, a torsion spring is fitted on the rotating shaft, one end of the torsion spring is fixedly connected to hinge support one, and the other end of the torsion spring is fixedly connected to hinge support two.

[0011] Preferably, the mounting bracket is located between the cylinder and the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The microphone diaphragm pad three-piece assembly machine is equipped with a feeding hopper, which allows the pads or diaphragms to slide downwards in an orderly manner, thereby improving the feeding speed.

[0014] 2. This microphone diaphragm and pad three-piece assembly machine is equipped with a feeding structure. Activating the electric push rod extends its piston rod, causing the push rod to move a push plate, which in turn pushes the pad into the mounting frame. A baffle prevents the pad from falling. The metal casing is placed on a conveyor belt, which is then activated. When the metal casing reaches below the mounting frame, the conveyor belt stops, and the cylinder is activated, extending its piston rod. The piston rod pushes the pad downwards, causing the torsion spring to deform under pressure. This removes the baffle's restriction on the pad's position, allowing the piston rod to push the pad into the metal casing, thus completing the pad installation. The machine uses three feeding structures to install the metal pad, diaphragm, and plastic pad. This feeding structure allows for the installation of the metal pad, diaphragm, and plastic pad without manual intervention, making it quick, convenient, and efficient, improving production efficiency and ease of use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a microphone diaphragm pad three-piece assembly machine, including a support frame 1, a conveyor belt 2, and a feeding structure 3. The top of the support frame 1 is fixedly connected to three cylinders 11, the conveyor belt 2 is located at the bottom of the cylinders 11, and the feeding structure 3 is provided with three cylinders. The feeding structure 3 includes a feeding hopper 31, a fixed seat 33 is fixedly connected to the front side of the feeding hopper 31, a bracket 34 is fixedly connected to the right side of the fixed seat 33, an electric push rod 35 is fixedly connected to the outer wall of the bracket 34, a push plate 36 is fixedly connected to the electric push rod 35, a mounting frame 37 is fixedly connected to the left side of the fixed seat 33, and hinge support 1 38 is fixedly connected to both the front and rear ends of the bottom of the mounting frame 37. Hinge support 1 38 is rotatably connected to hinge support 2 310, and a baffle 312 is fixedly connected to the outer wall of hinge support 2 310.

[0023] Furthermore, two support legs 32 are fixedly connected to the bottom of the feed hopper 31.

[0024] Furthermore, the feed hopper 31 consists of a rear feed hopper and a front feed channel, and the width of the groove of the feed channel is the same as the size of the diaphragm. A metal pad is placed in the rightmost feed hopper 31, a diaphragm is placed in the middle feed hopper 31, and a plastic pad is placed in the leftmost feed hopper 31. The pads slide onto the fixed seat 33 through the feed hopper 31. The feed hopper 31 allows the pads or diaphragms to slide downwards in an orderly manner, thereby improving the feeding speed.

[0025] Furthermore, a baffle is provided on the front side of the fixed base 33, a push plate 36 is slidably connected to the right side of the fixed base 33, and sliding grooves are provided on the left and rear sides of the fixed base 33.

[0026] Furthermore, hinge support 38 is rotatably connected to pivot shaft 39 on both the left and right sides. Pivot shaft 39 is rotatably connected to the left and right ends of hinge support 310, allowing hinge support 38 and hinge support 310 to rotate relative to each other.

[0027] Furthermore, a torsion spring 311 is fitted on the rotating shaft 39. One end of the torsion spring 311 is fixedly connected to the hinge support 38, and the other end of the torsion spring 311 is fixedly connected to the hinge support 310. The piston rod pushes the washer downward, causing the torsion spring 311 to be deformed under pressure, so that the baffle 312 no longer restricts the position of the washer.

[0028] Furthermore, the mounting bracket 37 is located between the cylinder 11 and the support bracket 1. The piston rod pushes the gasket inside the mounting bracket 37 into the metal housing, thereby completing the installation of the gasket.

[0029] Working principle:

[0030] In use, place a metal gasket in the rightmost feed hopper 31, a diaphragm in the middle feed hopper 31, and a plastic gasket in the leftmost feed hopper 31. The gaskets slide onto the fixed seat 33 via the feed hoppers 31. The feed hoppers 31 allow the gaskets or diaphragms to slide downwards in an orderly manner, increasing the feeding speed. Activate the electric push rod 35, causing its piston rod to extend and drive the push plate 36 to move. The push plate 36 then pushes the gasket into the mounting frame 37. The baffle 312 prevents the gasket from falling. Place the metal casing on the conveyor belt 2 and activate it, causing the conveyor belt 2 to move the metal casing. When the metal casing reaches the mounting frame 37... When the conveyor belt 2 is stopped, cylinder 11 is activated, causing the piston rod of cylinder 11 to extend. The piston rod pushes the gasket downward, causing the torsion spring 311 to deform under pressure. As a result, the baffle 312 no longer restricts the position of the gasket, and the piston rod pushes the gasket into the metal shell, thus completing the installation of the gasket. The installation of metal gaskets, diaphragms, and plastic gaskets is completed through three feeding structures 3. The installation of metal gaskets, diaphragms, and plastic gaskets can be completed without manual intervention through the feeding structures 3. It is quick and convenient to use, improves production efficiency, and is easy to use. The opening and closing of the conveyor belt 2, electric push rod 35, and cylinder 11 are all controlled by the control panel, and the circuit connection is existing technology, which will not be described in detail.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
