Recovery device for detecting second-hand memory cards

Abstract

The invention discloses a recovery device for detecting second-hand memory cards. The recovery device comprises a box body, a recovery cavity with an upward opening is formed in the box body, advancing wheel cavities which are symmetrical about the symmetry center of the recovery cavity in the front-back mode are formed in the front side part and the rear side part of the recovery cavity in a communicating mode. The left side part of the recovery cavity communicates with an advancing cavity, the left side of the advancing cavity communicates with a front-back through selecting cavity, the upper side part of the selecting cavity communicates with a pressing wheel cavity, and the left side part and the right side part of the pressing wheel cavity communicate with descending cavities which are symmetrical about the symmetry center of the pressing wheel cavity in a left-right mode. According to the recovery device, golden fingers of the second-hand memory cards are polished to remove the oxide layers on the surfaces, the quality of the memory cards is detected through power-on connection, and therefore the memory cards can be selected, the memory card recovery efficiency can be improved, the memory card failure detected due to the oxide layers of the golden fingers can be prevented, and the detection capability of the memory cards is improved.

Description

technical field [0001] The invention relates to the field of memory cards, in particular to a recovery device for detecting second-hand memory cards. Background technique [0002] Memory card is an independent storage medium used in mobile phones, digital cameras, portable computers and other digital products; second-hand memory cards are very popular in the market, and compared with new memory cards, they are cheaper and more popular with consumers , but in the process of recycling second-hand memory cards, due to the large amount of recycling, the efficiency of memory card detection is low, and some memory cards have an oxide layer on the surface of the gold finger, which will also make the memory card invalid, thereby reducing the recovery The economic benefits of the process, and the efficiency of manual detection is low, and it is time-consuming and labor-intensive, which is easy to cause unnecessary losses. A recovery device for detecting second-hand memory cards descr...
