Abstract

The method of cleaning deep internal channel of zirconia ceramic contact for raising rate of finished products of zirconia ceramic contact pin products is characterized by that it makes the propgation direction of the ultrasonic wave transmitted by ultrasonic instrument be identical to deep internal channel direction; and the ultrasonic wave used by said invention is pulse ultrasonic wave so as to increase the ultrasonic power of unit area. Said method can smoothly solve the microdust blocking problem of deep internal channel of zirconic ceramic contact pin, and can raise the rate of finished products of said zirconia ceramic contact pin products of 90% from original 65-70%, and can greatly save cleaning cost.

Description

Method for cleaning deep inner pore canal of zirconium oxide ceramic contact pin

Technical field

The present invention relates to the core component zirconium oxide ceramic contact pin of fiber active linker spare, be specifically related to the cleaning method of deep inner pore canal of zirconium oxide ceramic contact pin.

Background technology

Zirconium oxide ceramic contact pin is the core component of fiber active linker spare, and it is determining the quality of the joints of optical fibre.According to designing requirement, the deep inner pore canal diameter of zirconium oxide ceramic contact pin is a micron dimension, and inner duct length is the millimeter magnitude, and the form and position tolerance precision reaches the magnitude of 0.05～0.1 μ m.And in process, unavoidably leave grease and micronic dust in the inner duct.Therefore, the cleaning of deep inner pore canal is a highly difficult technology in the zirconium oxide ceramic contact pin machining process, if clean the quality and the yield rate that thoroughly will not influence product.Except that my institute, can reach three major companies that have only of industrialization in the world now, i.e. KYOCERA, TOTO, ADAMANT, they have the technical skill of oneself on cleaning, hold in close confidence mutually so far.From present known technology, traditional ultrasonic cleaning technology is still adopted in the cleaning of deep inner pore canal of zirconium oxide ceramic contact pin, this conventional clean method is difficult to solve deep inner pore canal of zirconium oxide ceramic contact pin comprehensively and cleans problem, occurring more inner duct micronic dust in the batch cleaning process stops up, thereby influence the yield rate of product, increase production cost of products.

Summary of the invention

Problem based on above-mentioned prior art exists the purpose of this invention is to provide a kind of method for cleaning deep inner pore canal that can improve zirconium oxide ceramic contact pin finished product rate.

The technical scheme of this cleaning method is as follows:

With the zirconium oxide ceramic contact pin homeotropic alignment on orifice plate, and the entrance hole that makes its deep inner pore canal is upwards;

2. the orifice plate that ceramic contact pin will be housed is placed on the shake below of ultrasonic instrument, and the ultrasound wave that shake is sent is consistent with the direction of deep inner pore canal, promptly enters from entrance hole, goes out for one relative with entrance hole, and ultrasonic cleaning is tens of minutes in cleaning fluid; Then with the ultrasonic cleaning tens of minutes in pure water of same method.Used ultrasonic instrument is the modified that Japanese WACo. produces.

3. change continuous ultrasound into impulse ultrasound, increased the ultrasonic power of unit area.

Above-mentioned cleaning program is the inventor through practical studies, gropes to obtain, and can solve deep inner pore canal of zirconium oxide ceramic contact pin micronic dust blockage problem smoothly, and the yield rate that makes product is by original 65～70%, brings up to present 90%.In addition, clean owing to change the continuous ultrasound cleaning into impulse ultrasound, increased the ultrasonic power of unit area, not only increased cleaning performance, and make the life-span of ultrasonic shake prolong one times, cost is cleaned in saving greatly, thereby has reduced production cost.

Fig. 2 is a ceramic contact pin diagrammatic cross-section of the present invention;

Specific implementation method

Method for cleaning deep inner pore canal of zirconium oxide ceramic contact pin concrete steps of the present invention are as follows:

Step 1:, remove carbonated drink with the high-purity air gun of high pressure then with arranging the rinsing in pure water of round-meshed orifice plate on the fluoroplastic plate;

Step 2: on orifice plate, and the entrance hole 3 that makes its deep inner pore canal 2 upwards with zirconium oxide ceramic contact pin 1 homeotropic alignment;

Step 3: the orifice plate that zirconium oxide ceramic contact pin will be housed is placed on the shake below of ultrasonic instrument, the ultrasound wave that shake is sent is consistent with the deep inner pore canal direction, open gearing, shake is put into the accurate cleaning fluid of metal together with the orifice plate that zirconium oxide ceramic contact pin is housed, treat ultrasonic cleaning;

Step 4: set ultrasonic power 1000W, frequency 40KHz/S, the recurrence interval is 6sec, pulse width is 2sec, after above-mentioned data validation, starts Ultrasound Instrument, ultrasonic cleaning 20 minutes;

Step 5: use the same method ultrasonic cleaning number minute in pure water.

Step 6: take out the orifice plate that zirconium oxide ceramic contact pin is housed, in pure water, soaked 5 minutes;

Step 7: the orifice plate of zirconium oxide ceramic contact pin will be housed, put into common Ultrasound Instrument rinse bath, under mobile pure water (resistivity＞5M Ω), ultrasonic rinsing 20 minutes.

Step 8: take out the orifice plate that zirconium oxide ceramic contact pin is housed, blow down the steam of orifice surface earlier with the high-purity air gun of low pressure, use the high-purity air gun of high pressure again, pursue the hole deaeration until all finishing by the ranks order.

Step 9: the orifice plate that zirconium oxide ceramic contact pin will be housed is put into baking oven, under 160 ℃, toasts 40 minutes, cuts off the power supply for taking out after 10 minutes.

Last CCD imaging pick test.
