Description

Technical Field

[0001] This utility model relates to a microphone soft kit fitting fixture, belonging to the field of microphone assembly technology. Background Technology

[0002] There are many types of handheld microphones, one of which is... Figure 1 As shown, the front end of the microphone 16 is MIC17, and the rear end is a silicone soft sleeve 18. Flexible wires 19 are soldered to the positive and negative terminals at the bottom of MIC17. This type of microphone 16 is installed at the corresponding mounting position on the microphone frame 20. The microphone 16 is fixed to the microphone frame 20 using methods such as adhesive application, interference fit, and anti-tamper locking.

[0003] like Figure 2 As shown, when the microphone 16 and the microphone frame 20 use an interference fit and anti-tamper bayonet structure, the assembly of such products is quite difficult. The difficulty lies in the fact that the silicone soft sleeve 18 has an upper and lower structure. The upper part covers the MIC 17, and because the MIC 17 is protected, this area cannot be subjected to compressive force. The lower part is solid soft silicone, which has a certain degree of rebound when compressed. The upper and lower parts are connected by a narrow silicone strip. The structural strength of the connection part is weak, and it is very easy to change when subjected to compressive or tensile force. This connection part also cannot be subjected to compressive or tensile force.

[0004] During assembly, employees can only hold the lower part of the silicone soft sleeve 18 by hand and insert it into the corresponding mounting hole in the microphone frame 20, then use a pressure rod to forcefully press it into the microphone frame 20. This installation method has the following shortcomings:

[0005] 1. High workload for employees;

[0006] 2. The silicone soft rubber sleeve 18 has a certain degree of elasticity, which may cause the lower part of the silicone soft rubber sleeve 18 to be improperly assembled due to the elasticity.

[0007] 3. The MIC17 is easily bumped or knocked.

[0008] 4. The assembly efficiency is not high. Summary of the Invention

[0009] The purpose of this utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a microphone soft sleeve fitting fixture to achieve multiple pressure on the silicone soft sleeve, solve the problem of silicone soft sleeve rebound, and achieve high product assembly quality.

[0010] The purpose of this utility model is achieved through the following technical measures: a microphone soft kit fitting fixture, including a middle frame positioning support base, a middle frame contour positioning base is provided at the center of the middle frame positioning support base, two linear bearings are respectively provided on the middle frame positioning support bases on both sides of the middle frame contour positioning base, guide shafts are slidably connected in the four linear bearings, a pressure head fixing plate is fixedly connected to the upper end of the four guide shafts, a pressure head extension block is provided at the center below the pressure head fixing plate, and a contour pressure head is fixedly connected to the lower end of the pressure head extension block.

[0011] As a further improvement to the above technical solution:

[0012] The lower ends of the four guide shafts are each fixedly connected with a second limiting ring.

[0013] Compression springs are provided on one of the guide shafts and on the guide shaft located diagonally opposite it.

[0014] The other two guide shafts are each fixedly connected with a first limiting ring.

[0015] The lower part of the mid-frame contour positioning seat is provided with a back plate, and side plates are provided on both sides of the back plate.

[0016] The back plate is evenly provided with several sets of suction nozzle components.

[0017] The suction nozzle component includes a countersunk hole on the back plate, and a circular through hole is provided in the center of the countersunk hole.

[0018] The circular through-hole connects to the negative pressure air passage.

[0019] The countersunk hole is elongated.

[0020] The contouring pressure head is located directly above the contouring positioning seat of the middle frame.

[0021] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are:

[0022] 1. Use a high-hardness metal material to make a contouring indenter, press down on the upper surface of the lower part of the silicone soft sleeve, and use the compressibility of the spring to achieve multiple presses on the silicone soft sleeve, thus solving the problem of the silicone soft sleeve's rebound.

[0023] 2. Using upper and lower limit rings can ensure the consistency of the downward displacement of the contouring indenter and guarantee the quality of product assembly;

[0024] 3. Using guide shafts and linear bearings ensures consistent directional guidance when the contouring indenter presses down, thus guaranteeing assembly quality;

[0025] 4. Use negative pressure suction to fix the microphone frame in place.

Detailed Implementation

[0033] 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.

[0034] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Example

[0036] like Figure 3 As shown, a microphone soft kit includes a middle frame positioning support 1, a middle frame contour positioning seat 10 at the center of the middle frame positioning support 1, a back plate 12 at the bottom of the middle frame contour positioning seat 10, side plates 11 on both sides of the back plate 12, and a plurality of suction nozzle components 9 evenly arranged on the back plate 12. The suction nozzle component 9 includes a countersunk hole 13 on the back plate 12. The countersunk hole 13 is elongated and has a circular through hole 14 at its center. The circular through hole 14 is connected to a negative pressure air passage. The suction nozzle component 9 adsorbs the middle frame under negative pressure, and the middle frame is firmly positioned by the middle frame contour positioning seat 10 and the suction nozzle component 9.

[0037] Two linear bearings 2 are respectively provided on the middle frame positioning support seats 1 on both sides of the middle frame contour positioning seat 10. Guide shafts 4 are slidably connected in the four linear bearings 2. The upper ends of the four guide shafts 4 are fixedly connected to the pressure head fixing plate 6. The pressure head extension block 7 is provided at the center below the pressure head fixing plate 6. The lower end of the pressure head extension block 7 is fixedly connected to the contour pressure head 8. The contour pressure head 8 is located directly above the middle frame contour positioning seat 10. Compression springs 5 ​​are respectively provided on one of the guide shafts 4 and the guide shaft 4 located diagonally thereon. First limiting rings 3 are fixedly connected to the other two guide shafts 4. Second limiting rings 15 are fixedly connected to the lower ends of the four guide shafts 4.

[0038] When the second limiting ring 15 abuts against the bottom end of the linear bearing 2, there is a gap between the first limiting ring 3 and the linear bearing 2 below. The adjustment of the first limiting ring 3 and the second limiting ring 15 satisfies the following state:

[0039] A. As Figure 4 As shown, the pre-assembled microphone 16 is placed on the middle frame positioning support 1 and fixed. At this time, the upper end face of the second limiting ring 15 is attached to the lower end face of the linear bearing 2 located above. The purpose is to prevent the contouring pressure head 8 from being lifted too high under the action of the compression spring 5, which would cause the contouring pressure head 8 to pull the microphone 16 upward too much.

[0040] B, such as Figure 5As shown, the assembled microphone 16 and microphone frame 20 are placed on the frame positioning support 1, and the microphone 16 is assembled with the contouring head 8. Then, the contouring head 8 is pressed down to press the silicone soft sleeve 18 of the microphone 16. At this time, the lower end face of the first limiting ring 3 is adjusted to be in contact with and fastened to the upper end face of the linear bearing 2. The function is to limit the downward displacement of the contouring head 8 and prevent the contouring head 8 from over-pressing the microphone 16.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
