Description

A microphone head welding tool

technical field

The utility model relates to a welding tool, in particular to a microphone welding tool. the

Background technique

The microphone is an energy conversion device that converts sound signals into electrical signals. It is a device that is exactly the opposite of the speaker. It is the two terminals of the sound equipment. The microphone is the input and the speaker is the output. Microphone is also known as microphone, microphone, microphone, microphone and so on. The microphone production process includes assembly, sorting, final welding, and packaging. The overall microphone is a cylindrical structure, which can be divided into various series according to different diameters, such as φ3 series, φ4 series, φ4.5 series, etc. The height of different types of microphones is also different, there are 3mm, 3.2mm, 4.0mm, 4.5mm and other sizes, there are solder joints on the PCB board on the upper side of the microphone, and enameled wires need to be welded on the solder joints, so a row of holes matching the diameter of the microphone is often drilled on the strip metal block. Then put the microphone in and position it before welding. Since there are many types of microphones, they are produced according to the needs of manufacturers in many cases, usually in small batches. Ordinary welding tools are completely based on the diameter of the microphone. And highly specially designed, there is almost no possibility of general use, so in the face of a wide variety of microphones, it is necessary to design and develop a lot of welding tools to meet the demand, the cost is very high, especially for small batch production, still cannot avoid manufacturing tooling , which is very inconvenient; at the same time, due to the gap between the microphone and the welding tool, the precision of the hole on the welding tool is very high. Some microphones will inevitably be squeezed when the cylindrical shell is processed, which will cause the roundness to change. The microphone head is put into the gap fit hole on the welding tool. After welding, the microphone head is difficult to take out naturally. It needs to be pushed out by the ejector rod. The back of the microphone head is equipped with a sound hole and a dustproof cloth. When the microphone is used, it will seriously affect the quality of the microphone, resulting in defective products. the

One side of the block is provided with a row of V-shaped lower notches corresponding to the V-shaped upper notch, and a spring is also arranged between the movable clamping block and the stopper. When the movable clamping block is in contact with one side of the fixed clamping block, the opening of the V-shaped upper notch and the opening of the V-shaped lower notch are just aligned to form a rectangular hole. block end, then put the microphone into the V-shaped upper gap, adjust the direction, and then loosen the movable clamping block, and under the action of the spring, the movable clamping block moves along the guide bar to the end of the fixed clamping block, V The V-shaped notch just clamps the other side of the microphone, the V-shaped upper notch and the V-shaped lower notch work together to clamp the microphone, and then perform welding. After welding, remove the movable clamping block, and the welded microphone can be It is easy to take out. When the diameter of the microphone changes, the V-shaped upper notch and the V-shaped lower notch can automatically adjust the positioning according to the diameter of the inserted microphone, clamp the microphone, and then weld it. This kind of tooling is easy to use and has strong universal performance. , can effectively maintain the welding quality of the microphone head.

As a preference, the contact part between the movable clamping block and the spring is provided with a spring limit hole, the contact part between the stopper and the spring is provided with a spring compression hole, and the contact part between the movable clamping block and the stopper is provided with a spring compression hole. A clamping block and a clamping joint that can be clamped to each other are respectively provided. Put one end of the spring into the spring compression hole, and the other end into the spring limit hole. The spring is not easy to bend and pop out after being compressed. Install the snap connector on the baffle and the snap block on the movable clamping plate. When in use, You only need to move the clamping block to snap into the clamping joint and then clamp the limit position, and then you can conveniently put the microphone into the V-shaped lower gap, so that when the microphone is inserted, the movable clamping block will not move again. It moves under the action of the spring and interferes with the installation of the microphone. After the microphone is installed, press the button on the clamping connector, the clamping connector and the clamping block are automatically disengaged, and the movable clamping block moves to clamp the microphone, which is very convenient to use. the

Preferably, a positioning hole is provided on the fixed clamping block, and a positioning pin is provided in the positioning hole, and the two ends of the fixed clamping block are bolted to the bottom plate. The bolt connection is easy to disassemble, and the positioning holes and positioning pins ensure that the position is accurate when reinstalling after disassembly. the

Preferably, the fixed clamping block includes a plurality of fixed clamping pieces, each of which has the same shape and is superimposed on each other to form the fixed clamping block. Due to the different heights of different types of microphones, when welding enameled wires, the fixed clamping piece plays a role in supporting and positioning the enameled wire, so the fixed clamping piece can be adjusted by increasing or decreasing the number of fixed clamping pieces according to the height of the microphone. The thickness is very convenient to use, the versatility is strong, no separate manufacturing mold is required, and the cost is low. the

Preferably, a fixing seat is connected to the bottom surface of the bottom plate, and the section of the fixing seat is wedge-shaped, wherein the end with a small thickness is close to the end of the fixed clamping block, and the end with a large thickness is close to the end of the stopper. The wedge-shaped fixing seat makes the upper side of the bottom plate inclined after the tool is placed on the workbench. When the microphone is installed in the V-shaped upper gap, as long as the position is basically corresponding, the microphone will automatically enter the V-shaped along the slope. In the upper gap, the installation of the microphone is more convenient. the

Preferably, both the fixed clamping block and the movable clamping block are made of copper. The copper material is not easy to rust, and its texture is soft, and its hardness is lower than that of the shell of the microphone, so when clamping the microphone, the clamp will not be deformed, thereby improving the welding quality. the

Therefore, the utility model has the beneficial effects of being convenient to use, strong in general performance, and capable of effectively maintaining the welding quality of the microphone. the
