Carrier for placing mobile phone cover and appearance inspection method of mobile phone cover

Abstract

The invention discloses a carrying tool for carrying mobile phone cover plates.The carrying tool comprises a base plate, grooves used for inserting mobile phones therein are formed in the base plate, in addition, the mobile phone cover plates on the base plate can be scanned through an infrared scanning device, and a microprocessor compares a scanning image of each mobile phone cover plate with a reference image so as to judge whether the corresponding mobile phone cover plate is qualified or not.By means of the carrying tool, the mobile phone cover plates can be prevented from being scratched when being stored, and infrared scanning inspection can be further conducted on the placed mobile phone cover plates, so that unqualified mobile phone cover plates are picked out efficiently.

Description

technical field [0001] The invention relates to a carrier for placing a mobile phone cover plate and a method for detecting the appearance of the mobile phone cover plate. Background technique [0002] After the mobile phone cover is made, the mobile phone cover needs to be stored. At present, the mobile phone cover is generally stored flat in the plastic tray or the mobile phone cover is inserted vertically into the slot and fixed by the support clip. When the cover is stored flat in the plastic tray, glass slag is likely to remain in the plastic tray, so that the glass slag will easily scratch the mobile phone cover; when the mobile phone cover is inserted vertically into the slot and fixed by the support clip, due to the Different batches of mobile phone covers have different shapes and sizes, so for different batches of mobile phone covers, the position of the support clip needs to be adjusted, and if the position of the support clip is not adjusted in place, the support...

[0002] After the mobile phone cover is made, the mobile phone cover needs to be stored. At present, the mobile phone cover is usually stored flat on the plastic tray or the mobile phone cover is inserted vertically into the socket and fixed by the support clip. When the mobile phone is When the cover is stored flat in the plastic tray, glass slag is likely to remain in the plastic tray, so that the glass slag is easy to scratch the mobile phone cover; and when the mobile phone cover is inserted vertically into the socket and fixed by the support clip, due to Different batches of mobile phone covers have different shapes and sizes, so for different batches of mobile phone covers, the position of the support clip needs to be adjusted, and if the position of the support clip is not adjusted properly, the support clip will hold the mobile phone cover The ink on the edge is scratched, and if the OCA optical film is attached to the mobile phone cover, the support clip is easy to crush the OCA optical film, causing air bubbles between the OCA optical film and the mobile phone cover, which will increase the size of the mobile phone cover defective rate

[0003] Moreover, after the mobile phone cover is made, the surface of the mobile phone cover may be damaged or contaminated with foreign matter. If such a mobile phone cover is assembled into a mobile phone, it will affect the display effect of the mobile phone. Therefore, after the mobile phone cover is made , it is necessary to carry out appearance inspection on the mobile phone cover to pick out the mobile phone cover with damage or foreign matter on the surface, so as to avoid the unqualified mobile phone cover from flowing into the mobile phone assembly process; at present, manual visual inspection is generally used to detect Whether the appearance of the mobile phone cover is qualified or not, the detection efficiency is low
