Abstract
The present invention relates to a manual cam base for finally testing a liquid crystal display module (LCM), which is used for testing the qualified rate of a flexible printed board on the LCM. The present invention is mainly composed of a base, a platform, a positioning part, a guide mechanism, a test element provided with a plurality of conducting terminals and a cam transmission mechanism, wherein an object to be testes is fixed in the positioning part, and the transmission mechanism is driven for driving the test element to reciprocate up and down. When the test element downwards presses the test end of the object to be tested, one-to-one complete and precise contact is formed between the conducting terminals and the test end. The present invention can effectively test the qualified rate of the object to be tested and can also reduce erroneous judgment and erroneous PIN phenomena.
Description
Technical field
The present invention relates to the manual cam pedestal of a kind of LCD module (LCM) final test, especially refer to that the test lead on a kind of flexible printed wiring board (FPC) interface that makes conducting end and LCM by manual operation accurately aims at the test pedestal that also contacts fully, to dwindle the tolerance clearance of tool and FPC test lead, guarantee its test position, avoid wrong PIN phenomenon.
Background technology
Soft/flexible print wiring board (Flexible Printed Circuit Board; Be called for short FPC) be printed circuit board (PCB) (Printed Circuit Board; Abbreviation PCB) product the most complicated in, that purposes is maximum, because of it possesses pliability, can utilize space size and shape to carry out the three-dimensional space three-dimensional wiring, make that product meets gently, thin, short, little requirement, therefore be widely used on the electronic products such as notebook computer, mobile phone, LCD, hard disk, printer, camera and automobile.
Known, tradition has following several as the described structure of Taiwan patent gazette in order to the testing apparatus of test flexible printed wiring board:
1. " probe test method and probe unit " (See Attachment 1) of No. the 379365th, Taiwan patent gazette Announcement Number, disclosed and a kind ofly risen towards the probe terminal, thereby tested having a medical check-up is contacted with on the probe terminal to test the device of this tested qualification rate of having a medical check-up by mounting table.
2. a kind of probe testing device of disclosing of " probe testing device and forming method thereof " (seeing Appendix two) of No. the 357265th, Taiwan patent gazette Announcement Number, comprise a substrate, one dielectric film, deflection extends on the first surface of substrate, this dielectric film has a first surface and contacts with the first surface of this substrate to form an area of space, be defined between the first surface of the first surface of this substrate and this dielectric film, make this dielectric film of part can enter this space; And a probe pattern, extend on the second surface of dielectric film, make probe form pattern, form test card by the probe that utilizes projection on the dielectric film whereby.
3. the testing apparatus that disclosed of " crossbar type probe tester " (seeing Appendix three) of No. the 497718th, Taiwan patent gazette Announcement Number, this device includes one first probe, one second probe, a cross bar and two probes, whether touch this connector and pass on signal by this cross bar, allow this tool judge the set connector of circuit board under test and whether install mistake by the lead of this second probe.
4. " elastic force probe wireless test device floats " (the seeing Appendix four) of No. the 368602nd, Taiwan patent gazette Announcement Number testing apparatus of being disclosed, comprise a device pedestal, there be fixing probe card, a top board to be parallel to probe card haply and fixation, and one probe keep the sheet fixation below probe card, the test probe of stretching, extension by this probe card also stretched by this probe keep sheet, in order to allow the circuit under testing on test probe and the printed circuit board (PCB) linearly aim at.
5. " combined tester probe improved structure " (seeing Appendix five) of No. the 378756th, Taiwan patent gazette Announcement Number, this probe structure is made up of probe and probe sleeve, it is characterized in that: this probe head end is made as the specification of multiple different-diameter size, tail end then all is made as the Plug Division of single specification, can plant in the probe sleeve in this Plug Division; And portion is provided with spring in the probe sleeve, this spring tail end directly is connected conducting with the electric wire head end, and the probe sleeve is fixed its tail end clamping after being placed on the spring cylindrical, and this wire terminations is made as copper rod, and these copper rods can directly be planted on the winding displacement of circuit test machine.
Though above-mentioned testing apparatus can be tested the conducting qualification rate of the test lead on the flexible printed wiring board, the FPC contraposition is difficult for when final test, and the phenomenon of easy wrong PIN, causes the puzzlement of test, and waste man-hour and cost.
Summary of the invention
Main purpose of the present invention is to solve above-mentioned defective, avoids the existence of defective, and the present invention changes traditional test mode with probe test, and dwindles the tolerance clearance of tool and FPC test lead, guarantees its test position.
Another object of the present invention is to replace the hand active grab with cam drive, and the FPC that uses when replacing traditional test with probe, avoids the phenomenon of FPC to dislocation PIN.
A further object of the present invention is to provide a kind of pedestal, and this pedestal is with manual operation, and simple and convenient, contraposition fast can be avoided again influencing production capacity because of the action that repeats increases the activity duration.
Another purpose of the present invention, it is universal to be that it is designed to, and can do similar in the future product and apply mechanically.
For achieving the above object, the manual cam pedestal of LCD module of the present invention (LCM) final test, in order to flexible printed wiring board (the Flexible PrintedCircuit on the test LCM, FPC) qualification rate, mainly by a pedestal, one platform, one location division, one guide mechanism, one testing element and a cam drive that is provided with a plurality of conducting end constitutes, whereby, thing to be tested is fixed in the location division, drive transmission device pumps to drive testing element, when testing element down is pressed on the test lead of thing to be tested, to form between conducting end and the test lead and reach accurate the contact one to one fully, but the qualification rate of this thing to be tested of Validity Test reduces False Rate and wrong PIN phenomenon.
