Device for detecting insulating property of vacuum coating nano-film layer of mobile phone rear cover

Abstract

The invention discloses a device for detecting the insulating property of a vacuum coating nano film layer of a mobile phone rear cover. The device includes a main controller, a supplied material conveying device which is used for conveying supplied materials of the vacuum coating mobile phone rear cover, a supplied material sensing and positioning device is used for sensing supplied materials ofthe rear cover of the vacuum coating mobile phone and positioning the supplied materials of the rear cover of the vacuum coating mobile phone, an automatic resistance measuring device which is used for measuring the resistance value of the positioned supplied material nano-film layer of the rear cover of the vacuum coating mobile phone; a laser coding device which is used for coding product identification codes on the edge of the vacuum coating mobile phone rear cover incoming material with qualified insulation performance; and a supplied material rear surface film coating device which performs film coating on the back surface of the rear cover supplied material of the vacuum coating mobile phone of which the insulating property is detected as qualified and comprises a printed product identification code and the rear cover supplied material of the vacuum coating mobile phone of which the insulating performance is detected as qualified; the device has the advantages that the vacuum coating mobile phone rear cover incoming material resistance value can be automatically measured so as to evaluate the insulation performance, manpower is saved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a device for detecting the insulation performance of a vacuum-coated nano-film layer on the back cover of a mobile phone. Background technique [0002] In the prior art, for the vacuum-coated mobile phone back cover made of plastic material, acrylic material or PC material, the mobile phone antenna needs to be embedded in advance because of its appearance, so in order not to affect the signal strength of the mobile phone antenna, it needs to be made of corresponding materials. The back cover of the mobile phone after vacuum coating has good insulation performance, and the main index for judging the insulation performance of the back cover of the mobile phone after vacuum coating made of the corresponding material is to measure its resistance value. When it is 4000 ohms, it is judged that its insulation performance is good. [0003] At the present stage, the measurem...

Problems solved by technology

[0003] At the present stage, the measurement of the resistance value of the back cover of the mobile phone after vacuum coating made of the corresponding material is generally carried out manually through the resistance value measuring instrument one by one. In this way, it will waste manpower and increase manual labor. cost, and makes it impossible to effectively increase the measurement speed and speed up the measurement cycle. At the same time, it is easy to touch or scratch the vacuum-coated mobile phone back cover made of the corresponding material during manual measurement, which makes additional defective products, and, in the resistance After the resistance value is measured, it is also necessary to coat the back of the back cover of the mobile phone after vacuum coating made of the corresponding material that the resistance value has been measured to protect it from being damaged or scratched by foreign objects, and the traditional coating process is also It is done manually, which also wastes manpower, increases labor costs, and makes lamination inefficient
