Embodiment Construction

[0006] Typical case: each movement detects the input current and the frequency of the current, and if necessary, detects the stop-second function of the movement and the current at stop-second, and detects the pulse characteristics of the output terminal. The number of contacts corresponding to each movement is a detection channel, such as detection of input current, output pulse, and stop seconds terminal. Five instrument contacts are a detection channel, and the stop seconds terminal can be combined. The number of channels of a typical instrument is 6 rows and 12 columns, that is, up to 72 movements can be detected. The movements arranged together are divided into 4 groups according to the number of odd and even rows and columns, namely: odd rows and odd columns are the first group, odd rows and even columns are the second group, even rows and odd columns are the third group, even rows and even columns For the fourth group, the corresponding instrument channels of each group...

Abstract

The invention relates to a timepiece movement tester. The objective of the invention is to solve the problem of fault testing caused by interference of adjacent timepiece movements. According to the technical scheme of the invention, a power source module of an instrument is fixed on a bottom plate of a casing; a signal acquisition module and a computing module are integrated on a PCB; the PCB is inserted in a casing; a display module is fixed on a panel at the front surface of the casing; wiring terminals are fixed on a panel at the back surface of the casing; each wiring terminal is connected with more than two movements; and each movement is corresponding to test channels of one instrument. The timepiece movement tester is characterized in that all test channels of the instrument are divided into four groups; each group of test channels acquires signals independently; acquired signals are temporarily stored; the computing module computes the signals in a centralized manner; and the display module displays test and computing results in a centralized manner.

Description

Technical field: [0001] The invention relates to a watch movement tester. Background technique: [0002] At present, in the detection of watch movements with multi-row and multi-column plates, there is a problem of mutual interference between adjacent movements, which may easily lead to false detection. At present, the multi-channel testers on the market generally start and vibrate all the movements at the same time, and test at the same time. The final test results show a certain proportion of random mistests, and the mistest results include judging bad movements as qualified products. And, a good product is judged as a defective product. Especially when digital instruments are used, the misjudgment rate is relatively high. Invention content: [0003] The purpose of the invention is to solve the problem of mismeasurement caused by adjacent interference of watch movements. [0004] The solution of the present invention is: a watch movement tester, which is composed of a...
