Description

A kind of buzzer test separator

Technical field

The present invention relates to electronic components test equipment manufacturing field, specifically be meant the piezoelectric ceramics buzzer test separator.

Background technology

Piezoelectric ceramics buzzing sheet is the sounding component of being fitted and being constituted by piezoelectric ceramic piece and metal substrate such as copper sheet, have thin thickness, in light weight, pronounce distinctly, characteristics such as anti-electromagnetic interference, low-power consumption; Because it is contactless, thereby noiselessness, reliability height.Be widely used in all kinds of electroacoustic sounding occasions, as communication products, industrial instrumentation, household electrical appliance and alarm: as products such as electronic watch, car horn, sound equipment, communication, remote sensing, calculator, electronic toys.

At present, the testing, sorting work in the piezoelectric ceramics buzzing sheet production process, mainly by manually operating, speed is slow, and efficient is low.And since the workman worked for a long time and be easy to generate fatigue, and people's sense of responsibility problem, go wrong easily during sorting, cause erroneous judgement to product, be about to defective work and be judged to certified products or opposite, will judge product by accident when being assemblied in the complete machine electronic product, greatly influence the reliability of electronic product, even the electronic product of waster appears, cause great quality accident when serious.

According to statistics, more skilled operative employee testing, sorting buzzing sheet when better state can only reach 1500 slices/hour, the testing equipment test speed of existing manufacturer production also has only 3600 slices/hour, and can only carry out testing, sorting to the large-size buzzing sheet of Φ 12-20mm, also can produce certain erroneous judgement, the more little False Rate of specification is high more.Existing testing equipment can't proper testing Φ 12mm following small size buzzing sheet, be that test speed is low, the False Rate height, so use test equipment is considerably less to the producer that the buzzing sheet carries out testing, sorting, greatly hinders the sound development of piezoelectric ceramics buzzing sheet industry.

The applicant entrusts Guangdong Science and Technology Information Inst. to carry out science and technology for " buzzer test separator " on February 22nd, 2010 and looks into newly, the novelty assessment report numbering: 20101199, and date 2010-2-26, the database of being inquired about is as follows:

1, " CSTAD "; 2, " national science and technology achievement storehouse "; 3, " Chinese patent "; 4, " SWIC "; 5, " CDDB "; 6, " china academia meeting paper database ".

Look into new descriptor: piezoelectric ceramics buzzing sheet; Test handler; Magazine; U moulding mixture groove; Test stands.

The innovative point of the applicant's trusting inquirying is with to look into new demand as follows:

1) the load mode that adopts extra quality box alternately to switch is used cylinder to carry out magazine and is switched, and last magazine is single many, the structure of single face breach blowing, is easy to manually change the magazine load.

2) the U moulding mixture groove multi-disc location structure that adopts the bottom to locate, hopper is two cuboid clampings frame modes together, the locating hole of buzzing sheet is a upper guide to, bottom to buzzing sheet bottom and the spacing U type location structure in both sides, and this structure has realized simple multi-disc buzzing sheet blanking and pinpoint function simultaneously.

3) mode of employing skewback guiding waste discharge material, adopt test back certified products and waste product to fall simultaneously, by control waste product station cylinder, promoting skewback makes waste product fall into the waste product storehouse by the skewback guiding, certified products then vertically fall into qualified storehouse, realized that the discharge time is shorter, structure is simpler, the function of better effects if.

4) the accurate test mode that adopts the buzzing sheet to stand and test.

Hold basic identical within the claim of above-mentioned innovative point and present patent application.

Through inquiry, five pieces of relevant documents are arranged:

[1] " design of material Grading System and realization ", author: Wang Pengda, Master's thesis.This paper has studied the design and the realization of material separator detection system and control system.Point out that separator is a kind ofly to utilize photoelectric technology analysis identification material quality, and the high technology equipment that utilizes compressed air that material inferior is rejected, can effectively improve the quality grade of material, improve the automaticity of process technology.

[2] " application of static frequency measurement sorting unit in the piezoelectric ceramics automatic sorting system ", the author: Xu Huajun is published in " communication and the radio and television " second phase in 2003.This paper has studied the application of static frequency measurement sorting unit in the piezoelectric ceramics automatic sorting system, has introduced patent of invention " static frequency measurement sorting unit " and the application in the piezoelectric ceramics automatic sorting system thereof.

[3] " the static frequency measurement method for separating and the device of piezoelectric ceramic piece and device ", inventor: Xu Huajun etc., the patent No.: 011271515,, it discloses the static frequency measurement method for separating and the device of piezoelectric ceramic piece and device, is the core technology of document [2], its frame for movement is simple, adopt software to carry out the test of complete machine, adopt fiber orientation, accurate positioning.

[4] " testing and sorting method and the device of platoon formula electronic device ", inventor: Chen Xiaozheng etc., the patent No.: 2005100387763, a kind of testing and sorting method and device of platoon formula electronic device are disclosed, adopting a plurality of photoelectric sensors and travel switch to carry out multiple spot detects, accurate positioning, fault accuracy of judgement, discrimination height.

[5] " a kind of Test handler ", inventor: Wang Jianming etc., the patent No.: 2008200446120, a kind of Test handler is disclosed, its feed mechanism has two covers material loading assembly arranged side by side mutually at least, testing, sorting mechanism is arranged on the L-shaped test support, can accurate positioning and high-speed, high-precision testing element.

Look into new conclusion: the domestic bibliographical information that Test handler has been arranged, as document [4], [5], especially document [5] is the highest with this authorized item degree of correlation, but the innovative point 1-4 that the piezoelectric ceramics buzzer test separator of this authorized item research is possessed does not all have embodiment in document [5].In above-mentioned range of search, domestic existing part relates to the bibliographical information of this authorized item technical characterstic, but does not see the bibliographical information of the piezoelectric ceramics buzzer test separator that possesses this authorized item technical characterstic simultaneously.
