Cable blind sample manufacturing device and method for testing

Abstract

The invention discloses a cable blind sample manufacturing device for testing. The device comprises an automatic pay-off part, an identification position detection part, a spraying part and an automatic take-up part, wherein the automatic pay-off part and the automatic take-up part are driven by a motor, and a to-be-tested cable keeps certain tension between the automatic pay-off part and the automatic take-up part; the identification position detection part is arranged between the automatic pay-off part and the automatic take-up part and used for detecting the starting point and the end pointof a detection identifier; the spraying part starts spraying or stops spraying according to a detection result of the identification position detection part. According to the device, a blind sample of an outer cable sample can be manufactured efficiently at low cost, the labor resource cost is reduced, the situation that manually manufactured blind samples are not sufficiently sprayed or even missing spraying occurs is eliminated, and the phenomenon that quality of the blind samples is not uniform due to the fact that a manual manufacturing technology is uncontrollable is eliminated; meanwhile, winding of the sample with the manufactured blind sample can be standard and meets testing requirements.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a device and method for making blind cable samples for testing. Background technique [0002] At present, the confidentiality requirements of testing work are getting higher and higher. In order to ensure fairness in many testing tasks, it is necessary to smear the logo on the surface of the cable to be tested before starting the test, and prepare a blind sample before starting the testing work. The length of the cable samples to be tested generally ranges from tens of meters to hundreds of meters, and each meter will have a mark. Traditionally, the method of manual smearing is used to find the mark one by one meter, and use a marker pen or other tools to smear the mark. It is labor-intensive, and the smearing effect cannot fully meet the requirements of blind samples. Insufficient smearing or even missed coatings often occur, which cannot meet the confidentiality requirements; ...

The length of the cable samples to be tested generally ranges from tens of meters to hundreds of meters, and each meter will have a mark. Traditionally, the method of manual smearing is used to find the mark one by one meter, and use a marker pen or other tools to smear the mark. It is labor-intensive, and the smearing effect cannot fully meet the requirements of blind samples. Insufficient smearing or even missed coatings often occur, which cannot meet the confidentiality requirements; Afterwards, there may be coiled confusion or even knotting, which will seriously affect the test efficiency and even cause serious deviations in the test results.
