Description

Technical Field

[0001] This utility model relates to the field of microphone welding fixture technology, specifically, to a microphone welding positioning fixture. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. The most common type is the electret condenser microphone. This type of microphone has a cylindrical structure. There are two solder points on the PCB board on the front of the microphone. When using it, one end of the wire needs to be soldered to the solder point first, and then the other end of the wire needs to be soldered to the circuit board. Therefore, a complete microphone consists of two parts: a cylindrical microphone body and a wire.

[0003] According to the search, a high-efficiency microphone welding positioning device was published in China on January 25, 2022, with patent publication number CN215616010U. It is roughly described as including a base, with an installation groove at the center of the top outer wall of the base, and a motor is installed on the bottom inner wall of the installation groove by bolts. A turntable is installed on the output end of the motor by bolts.

[0004] Although the above-mentioned existing technical solutions improve the processing efficiency of microphone welding, the clamping plate is prone to wear on the microphone when unloading the microphone, which reduces the quality of the microphone. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a microphone welding and positioning fixture to solve the problem mentioned in the background technology that the clamping plate easily causes wear on the microphone during unloading, thereby reducing the quality of the microphone.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a microphone welding positioning fixture, comprising a base and multiple clamping plates. The top of the base has a mounting groove, inside which a stepper motor is installed. The output end of the stepper motor passes through the mounting groove and connects to a turntable. The turntable has multiple evenly distributed limiting grooves. The inner sidewalls of the multiple limiting grooves have clearance grooves near the edge of the turntable. The multiple clamping plates are located inside the multiple limiting grooves. A spring is provided between each clamping plate and the clearance groove. A support plate is fixedly connected to the bottom of each clamping plate. The bottom of the turntable has multiple limiting grooves that slidably connect with the support plates. An inclined discharge groove, cooperating with the limiting grooves, is provided at the edge of the top of the base. An active lever, cooperating with the inclined discharge groove, is fixedly connected obliquely to the top of the base.

[0009] By adopting the above technical solution, the microphone is inserted into the limiting groove, and the spring pushes the clamping plate to clamp and fix the microphone, which facilitates welding of the microphone. The stepper motor drives the turntable to rotate regularly, and the turntable drives the microphone, clamping plate and support plate to rotate. When the support plate moves to the position of the inclined discharge chute, the active lever and the passive lever cooperate to push the support plate and clamping plate to move, so that the clamping plate and support plate are away from the microphone. This allows the welded microphone to fall from the limiting groove into the inclined discharge chute, thereby achieving the purpose of discharge and avoiding wear on the microphone during unloading.

[0010] Optionally, the active lever is rotatably connected to a plurality of first rollers that cooperate with the passive lever, and the edges of the plurality of support plates are rotatably connected to a plurality of evenly distributed second rollers, one end of each of the plurality of second rollers being in close contact with the limiting groove.

[0011] By adopting the above technical solution, the first roller is used to reduce the friction between the active lever and the passive lever, and the second roller is used to reduce the friction between the support plate and the limiting groove, thereby improving the smoothness of equipment operation and reducing equipment wear.

[0012] Optionally, a first anti-slip pad is provided on the inner sidewall of each of the multiple clamping plates, and a second anti-slip pad that cooperates with the first anti-slip pad is provided on the inner sidewall of each of the multiple limiting grooves.

[0013] By adopting the above technical solution, the first anti-slip pad and the second anti-slip pad work together to increase the friction between the device and the microphone, thereby reducing the probability of the microphone tilting and improving the stability of the microphone.

[0014] Optionally, each of the clamping plates has a slanted guide fixedly connected to its top end.

[0015] By adopting the above technical solution, the inclined guide is used to facilitate personnel to insert the microphone into the limiting groove, thereby saving manpower.

[0016] Optionally, the bottom end of the turntable is rotatably connected to a plurality of evenly distributed ball bearings, the bottom ends of which are in close contact with the top end of the base.

[0017] By adopting the above technical solution, the ball bearings are used to provide uniform support to the turntable, preventing the turntable from tilting, thereby improving the stability of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This microphone welding and positioning fixture inserts the microphone into a limiting groove, causing a spring to push a clamping plate to hold and fix the microphone, facilitating welding. A stepper motor drives a turntable to rotate regularly, which in turn rotates the microphone, clamping plate, and support plate. When the support plate moves to the position of the inclined discharge chute, the active and passive levers cooperate to push the support plate and clamping plate to move away from the microphone. This allows the welded microphone to fall from the limiting groove into the inclined discharge chute, achieving the purpose of discharge and avoiding wear on the microphone during unloading.

[0029] 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.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1-6 A microphone welding positioning fixture includes a base 1 and multiple clamping plates 2. The top of the base 1 has a mounting groove, inside which a stepper motor 3 is installed. The output end of the stepper motor 3 passes through the mounting groove and connects to a turntable 4. The turntable 4 has multiple evenly distributed limiting grooves. The inner sidewalls of the multiple limiting grooves have clearance grooves near the edge of the turntable 4. Multiple clamping plates 2 are located inside the multiple limiting grooves. Springs 5 ​​are provided between each clamping plate 2 and the clearance groove. Support plates 6 are fixedly connected to the bottom ends of each clamping plate 2. Multiple limiting grooves 7 are slidably connected to the bottom end of the turntable 4 and slidably connected to the support plates 6. An inclined discharge groove 8, matching the limiting grooves, is provided at the edge of the top of the base 1. An inclined discharge groove 8 is fixedly connected to the top of the base 1. The active lever 9, which cooperates with the discharge chute 8, and the bottom ends of multiple support plates 6 are all fixedly connected to passive levers 10, which cooperate with the active lever 9. When the microphone is inserted into the limiting groove, the spring 5 pushes the clamping plate 2 to clamp and fix the microphone, so as to facilitate welding of the microphone. The stepper motor 3 drives the turntable 4 to rotate regularly. The turntable 4 drives the microphone, clamping plate 2 and support plate 6 to rotate. When the support plate 6 moves to the position of the inclined discharge chute 8, the active lever 9 cooperates with the passive lever 10 to push the support plate 6 and clamping plate 2 to move, so that the clamping plate 2 and support plate 6 are away from the microphone, so that the welded microphone falls from the limiting groove into the inclined discharge chute 8, thereby achieving the purpose of discharge. This avoids wear on the microphone during unloading.

[0032] Reference Figures 3-7Multiple first rollers 11 that cooperate with the passive lever 10 are rotatably connected to the active lever 9. Multiple evenly distributed second rollers 12 are rotatably connected to the edges of multiple support plates 6. One end of each of the multiple second rollers 12 is in close contact with the limiting groove 7. The first rollers 11 are used to reduce the friction between the active lever 9 and the passive lever 10, and the second rollers 12 are used to reduce the friction between the support plate 6 and the limiting groove 7, thereby improving the smoothness of equipment operation and reducing equipment wear.

[0033] Reference Figure 1 and Figure 2 Each clamping plate 2 has a first anti-slip pad 13 on its inner sidewall, and each limiting groove has a second anti-slip pad 14 on its inner sidewall that cooperates with the first anti-slip pad 13. The first anti-slip pad 13 and the second anti-slip pad 14 cooperate to increase the friction between the device and the microphone, thereby reducing the probability of the microphone deflecting and improving the stability of the microphone.

[0034] Reference Figure 1 and Figure 2 Each of the clamping plates 2 has a fixedly connected inclined guide 15 at its top. The inclined guide 15 is used to facilitate the insertion of the microphone into the limiting groove, thereby saving manpower.

[0035] Reference Figure 6 The bottom of the turntable 4 is rotatably connected to a number of evenly distributed balls 16. The bottom of the balls 16 is in close contact with the top of the base 1. The balls 16 are used to provide even support for the turntable 4 and prevent the turntable 4 from tilting, thereby improving the stability of the equipment.

[0036] It should be further explained that the stepper motor 3 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it and have not improved its structure and function. Its setting method, installation method and electrical connection method can be debugged and operated by those skilled in the art according to the requirements of its instruction manual. It will not be described in detail here. The stepper motor 3 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use requirements to facilitate the operator's operation and control.

[0037] In summary, the working principle and process of this microphone welding positioning fixture are as follows: First, the microphone is inserted into the limiting groove, causing the spring 5 to push the clamping plate 2 to clamp and fix the microphone, facilitating welding. The stepper motor 3 drives the turntable 4 to rotate regularly. The turntable 4 drives the microphone, clamping plate 2, and support plate 6 to rotate. When the support plate 6 moves to the position of the inclined discharge chute 8, the active lever 9 and the passive lever 10 cooperate to push the support plate 6 and clamping plate 2 away from the microphone. This allows the welded microphone to fall from the limiting groove into the inclined discharge chute 8, achieving the purpose of discharging material for unloading. To prevent wear on the microphone, the first roller 11 reduces friction between the active lever 9 and the passive lever 10, and the second roller 12 reduces friction between the support plate 6 and the limiting groove 7, thereby improving the smoothness of equipment operation and reducing equipment wear. The first anti-slip pad 13 and the second anti-slip pad 14 work together to increase friction between the equipment and the microphone, thereby reducing the probability of microphone tilting and improving microphone stability. The inclined guide 15 facilitates the insertion of the microphone into the limiting groove, thereby saving manpower. The ball bearing 16 provides uniform support to the turntable 4, preventing the turntable 4 from tilting, thereby improving equipment stability.

[0038] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
