Abstract

The utility model relates to a measurement and junction device of a crystal vibrator characteristic inspector. The measurement and junction device comprises a support and a product pedestal, wherein an electrode plate mounting strip is arranged on the support and is connected with one side of the product pedestal; a junction platform is arranged at the position in level with the electrode plate mounting stripe connected with one side of the product pedestal; an insulating check block is arranged on the electrode plate mounting strip; a plane teeth-shaped metal junction is arranged at the position in level with the insulating check block and at one side of the junction platform opposite to the insulating check block; a measurement loop component is connected with the other side of the junction platform by a connecting line; and a signal line is arranged at the other side of the measurement loop component. In the measurement and junction device, due to the communication form of the teeth-shaped metal junctions and a product, the contact area is enlarged, so that the poor contact can not be caused in the measurement, the error measurement and the false rate can be reduced, the false rate of the DLD (Dark Line Defect) measurement by the original measurement contact form is about 1%, and the false rate after improvement is about 0.3%, therefore, the reject ratio of the testing work can be reduced by 0.7%, thereby reducing the bad loss for enterprises.

Description

Crystal oscillator characteristic check machine is measured contact arrangement

Technical field

The utility model relates to the mensuration contact arrangement in the mechanical field application, especially relates to a kind of mensuration contact arrangement of crystal oscillator characteristic check machine.

Background technology

Crystal oscillator characteristic check machine principle of work is: goods supply unit 21 as shown in Figure 3 moves on the device conveying belt 23 each goods to packaged ticker one by one and continuously from charging tray and places in pedestal; Conveying belt 23 by counterclockwise one by one station move; Each is checked that station 221,222,223,224 is accomplished one by one the inspection of each electrical specification of goods is judged; In classification discharge portion 24, classification is placed in the different goods keeping boxes 241 with defective products with non-defective unit at last.

The second inspection station 222 is to implement crystal oscillator DLD characteristic check and the good station of not judging; The content of DLD inspection is: whether the deviation that crystal oscillator is sent out vibration frequency and resistance of equal value under the inspection different driving power is in claimed range; This characteristic check is well had relatively high expectations to the contact of measuring contact, otherwise the resistance measurement value of equal value under each driving power has error, and it is as shown in Figure 2 that DLD originally measures the contact mode; Moulding cap contact 12 pays goods pin 13 pressures on electrode slice 11 with the action forward of contact platform 4; Analyzer is measured goods 10 through signal wire 9 and mensuration loop assembly 8 and electrode slice 11 and goods pin 13 formation loops, all is the plane because of moulding cap contact 12 with electrode slice 11 front ends; When pin 13 is compressed; Real contact area is likely a point that area is very little, in case reasons such as machine vibration cause loose contact probably, error measurement takes place.

Summary of the invention

In order to overcome above-mentioned defective; The utility model provides a kind of crystal oscillator characteristic check machine to measure contact arrangement; Through changing the form of original electrode slice and goods conducting into form through profile of tooth metallic contact and goods conducting; Increase contact area, made when measuring, not come in contact badly, reduced error measurement and False Rate.

The technical scheme that its technical matters of the utility model solution is taked is: a kind of crystal oscillator characteristic check machine is measured contact arrangement; Comprise support and goods pedestal; The electrode slice mounting bar is installed on the support, and the electrode slice mounting bar is connected with goods pedestal one side, and the electrode slice mounting bar of the side that is connected with the goods pedestal aligns and the contact platform is installed on the mean place; The electrode slice mounting bar is provided with insulating spacer; On one side of the contact platform relative with insulating spacer and the insulating spacer flush planar tooth metallic contact is installed, opposite side is connected with through line and measures the loop assembly, and the opposite side of measuring the loop assembly is equipped with signal wire.

The beneficial effect of the utility model is: through changing the form of original electrode slice and goods conducting into through profile of tooth metallic contact and goods conducting form, change the part of former installing electrodes sheet the block of engineering plastics insulating material into, change the original cap contact of moulding into the profile of tooth metallic contact again; Then with the original signal line with measure the support of loop assembly and move and be installed to contact one side through new making; With contact and mensuration loop assembly conducting, such mensuration way of contact has guaranteed that contact electrode and goods pin have a plurality of contact points, have increased contact area with line; Make when measuring, do not come in contact bad; Reduce error measurement and False Rate, the misinterpretation rate that former mensuration way of contact DLD measures about 1%, improved misinterpretation rate about 0.3%; Can reduce by 0.7% inspection operation fraction defective, for enterprise reduces bad loss.
