How To Write The Technological Process Of Horn Production

Hardware: first you need to purchase raw material, 4 big basin (aluminum, iron material), washers, T iron, magnet, and then the three major software: voice coil, drum paper, elastic wave, there are some small accessories: terminals, screws, washers, dust-proof net, dust cap, brocade silk, tin line, glue (washers with glue, plastic magnetic circuit AB glue, elastic wave, drum paper edge glue, rubber damping, center AB glue, plastic dust cap, rubber gasket, dust cap reinforcing glue, etc.) production process: first step: to connect the terminals and basin (note: terminal left is right, red is black, width is narrower) the second step: Preparing rubber glue wind batch screw connects the washers and basin, the third step: prepare T iron, magnet, AB glue, glue magnetic gauge before and even good pot rack in the department of China, made to T AB glue (a uniform mixing ratio) on the T iron play glue the magnet and set into the magnet location gauge, the rotating magnet with magnets and T iron connection edge glue a week with no break glue no gap for the standard, after waiting for AB glue dry remove rules called magnet AB glue and set on the pot rack positioning rules and then put on basin rotating weeks washers connected to the magnet edge glue a week with no break glue no gap for the standard, the magnetic circuit is ready. Step 3: after magnetic circuit such as glue dry remove positioning rules, prepare glue machine, glue, voice coil, elastic wave and sound drum paper, washer, gauge, voice coil positioning platform, digital caliper, etc., will first note trap into the corresponding rules and caliper to locate the position height = (voice coil picture - washers thickness) present 2 ", and then play Boeing circles glue, and then set a voice coil connection on the elastic wave into T iron column and move in the wave of the fully bonded (the voice coil must be put in place can't skew) then call elastic wave and voice coil joint center AB glue, then processed drum paper sets into the voice coil and gently press, brocade silk to aim at terminals. Then put AB glue in the center of the joint between drum paper and voice coil. (precautions for central glue: mix AB glue evenly, do not have too much glue, and the overflow and leakage of glue will produce rubbing ring.) press the edge of drum paper gently with a fixture to make it overflow and then type and dry. Step 3: Pull out sound rules after the glue is completely dry, prepare soldering iron, tweezers, wire cutters, magnetizing machine, glue machine, glue, dust cap, tin wire, audio equipment, measuring the voice coil wire winding on the brocade silk, lead can't jump too tight, the drum of paper on the back of the brocade silk with tweezers to pick up the empty wear into the terminal, the voice coil with los iron wire and brocade silk welding, solder joint to full brightness can't virtual false welding leakage welding, welding with wire cutters will be redundant lead kam silk cut, then buckle the speaker put through the terminal hole kam silk straightening, shearing reserved 8-12 mm, will be reserved kam silk back helps the brocade silk have certain radian terminal hole when the vibration drum paper, Then the brocade silk wire and terminal welding spot requirements are the same as above, prepare the magnetizing machine to connect the wire and adjust the voltage to the horn to rush the magnetism, charge the magnetic horn into the test room to test then prepare glue, glue machine, dust cap finally is typesetting dry. Now the product is basically finished, but there are special requirements for the horn also need to drum paper brush layer of glue, such as: waterproof glue: drum paper cloth edge soft glue, dust cap reinforcing glue and so on.
