Description
Technical field
The present invention relates to earphone manufacturing technology field, particularly relate to a kind of foaming earphone covers production technology.
Background technology
The user of phone, Voice & Video player and other mobile devices selects earphone for the consideration of the aspect such as convenience, privacy more and more.The form of earphone is varied, classifies according to its transducing mode, mainly contains moving-coil mode, dynamic iron mode, electrostatic and electromagnetic type; Classify from separating type, semi open model and closed can be divided into; Then have ear type, ear suspension type, In-Ear and wear-type from wearing formal classification, general ear type and In-Ear due to its structure comparison small and exquisite, so Application comparison is extensive.
PlayGear Stealth and In-Ear Headphones all have as lower part, the size of this part is confirmed as being inserted in duct at least partly, although these earphones can provide in some cases and preferably show, but be difficult to reach reliable and comfortable installation for some users, this is because the ear shape of the user of each wear headphones is different, so cannot design according to the ear shape of single individual and manufacture earphone, at this moment in order to eliminate this defect, a lot of earphone all can overlap an earphone covers in the fabrication process on that a part of earphone pleasant, earphone covers generally adopts sponge or rubber to make, the different demands of difformity ear to earphone are made up by the performance of the elastically deformable of sponge or rubber.
As shown in Figure 1, the production process of conventional earphone cover:
First: the raw material A material and the B material that manufacture earphone covers enter batch mixing reactor 03 respectively by the first hopper 01 and the second hopper 02, fully mix in batch mixer 03;
Second: flow in the some die holes 06 on mould 05 in batch mixing reactor 03 after mixing by efferent duct, mould 05 is arranged on the rotating disk 04 of rotation, when mould 05 is just to efferent duct, rotating disk 04 stops operating, until all filled mixed material in all die holes 06 on mould 05;
3rd: on efferent duct, transducer is set, after all being filled mixed material in all die holes 06 on one of them mould 05, transducer by Signal transmissions to the controller of rotating disk 04, control rotating disk 04 to rotate, when another mould 05 is just to efferent duct, transducer then by Signal transmissions to the controller of rotating disk 04, make it stop operating;
4th: the mould 05 filling mixed material enters baking box 07 successively to carry out toasting and foaming;
5th: after the mould 05 toasted is sent baking box 07, the whole mould 05 of manipulator 08 is utilized to move on to Cutting platform 09, and the shaping earphone plug in mould 05 is poured out, then vacant mould 05 is sent back on rotating disk 04 by manipulator 08, carries out work next time;
6th: on Cutting platform 09, utilize sponge cutting machine to be split by the some earphone covers linked together;
7th: the earphone covers after segmentation is screened, then packs, deliver.
Adopt manufacture foaming earphone covers in this way and have following shortcoming:
1, earphone covers forming die structure is complicated, and manufacture difficulty, die cost is high;
2, because mould size is larger, so baking box also arranges huger, the cost of baking box is caused to increase, simultaneously because mould is arranged on panoramic table, the bake region of baking box will be caused like this not make full use of, to make the energy-output ratio of baking box large, loss is many, can not meet the energy-saving and emission-reduction plan of national requirements;
3, mould is provided with several die holes, finished product easily links together during fabrication, so just need to split with sponge cutting machine, be easy to during segmentation cause earphone covers to become substandard products or waste product, production qualification rate is made to reduce like this, too increase the operation of subsequent sort qualified product simultaneously, make manufacturing cost increase further;
The cost of the earphone covers 4, produced according to this production method is high, with φ 8/ φ 12 × 15mm, thickness is the open circles taper foaming earphone covers of 2mm is example, and often producing an about cost of this earphone covers is one yuan, so just make the cost of whole earphone improve, affect follow-up earphone and sell.
Summary of the invention
The object of the invention is to solve the problem, a kind of foaming earphone covers production technology is provided, it has that manufacturing equipment is simple, manufacturing process is few, mould structure is simple and long service life, product one-shot forming and the advantage that Forming Quality is good, production cost is low and energy resource consumption is low.
