Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as Figure 1-4 As shown, a height testing device according to the present invention includes a cover plate 1, a sliding groove 2, two transmission shafts 5, a sliding block 7, an optical fiber fixing block 10, an optical fiber head 11, a shaft fixing bottom plate 12 and a reference position The fixed plate 13, the cover plate 1 is fixed on the top of the sliding groove 2 by screws, the cavity of the sliding groove 2 is nested with a shaft fixing plate 3, and the counterbore of the shaft fixing plate 3 is nested with a first The spring 4 , the other end of the first spring 4 is pressed against the bottom surface of the cover plate 1 . The cover plate 1 is fixed on the tooling, and when the tooling is pressed down, only the cover plate 1 and the slide groove 2 move along with it, and the other parts only move a little so as to completely contact with the cor...

Abstract

The invention relates to the technical field of height testing of parts on a PCBA (Printed Circuit Board Assembly), and in particular relates to a height testing device; the height testing device comprises a cover plate; the cover plate is fixedly arranged on the top of a sliding groove through a screw; a shaft fixing plate is arranged in the cavity of the sliding groove in an embedding manner; a first spring is arranged between the shaft fixing plate and the cover plate; two transmission shafts and two ends of an optical fibre fixing shaft are respectively fixed on the shaft fixing plate and a shaft fixing bottom plate in an embedding manner; a second spring is also embedded in the transmission shafts; a testing head is fixedly arranged on the bottom head face of a sliding block; the other end of the testing head is sequentially embedded in the shaft fixing bottom plate and a reference position fixing plate at intervals; an optical fibre head is fixedly arranged on an optical fibre fixing block; and a steel disc matched with the optical fibre head is fixedly arranged on one side surface of the sliding block. After the height testing device disclosed by the invention is used, the working efficiency is greatly increased; the measurement time and the measurement error are reduced; and thus, the production cost is further reduced. The height testing device disclosed by the invention has the advantages of being simple in structure, reasonable to set, low in manufacture cost and the like.

Description

technical field [0001] The invention relates to the technical field of height testing of components on a PCBA, in particular to a height testing device. Background technique [0002] PCBA is the abbreviation of Printed Circuit Board + Assembly in English, that is to say, the empty PCB board passes through the SMT upper part, and then goes through the whole process of DIP plug-in, referred to as PCBA. [0003] As we all know, the current method for checking the height of parts on PCBA is: manually use digital calipers to measure the height of parts. Although this method is simple, its disadvantage is that the measurement time is long and the error is large. Therefore, it is necessary to provide a testing tool for checking the height of components on the PCBA. Contents of the invention [0004] The object of the present invention is to provide a height testing device with simple structure, reasonable design and convenient use in view of the defects and deficiencies of the p...
