Memory card rotary disk and processing method thereof

Abstract

A memory card rotary disk and its processing method are disclosed, wherein the memory card turntable comprises a turntable main body, the turntable main body is provided with a plurality of receivinggrooves for receiving smart cards along the circumferential direction, one end of each receiving groove is an opening for allowing in and out of the card, the opening is located on the outer cylindrical surface of the turntable, the other end of each receiving groove extends toward the inside of the turntable, one or more guide partitions for guiding and separating the card as it enters and exitsthe receiving groove are provided on the inner side of each receiving groove, The guide partition partitions the opening of the receiving slot into at least two card inlets and outlets, each card inlet and outlet and a space in which the card inlet and outlet extend in the receiving slot form a card storage slot for a smart card. The structure of the memory card rotary disk is ingenious, which cangreatly reduce the processing difficulty of the memory card rotary disk and improve the processing efficiency, so the memory card rotary disk has the advantages of convenient processing and good useeffect.

Description

technical field [0001] The invention relates to a smart card receiving machine, in particular to a card storage turntable and a processing method thereof. Background technique [0002] The smart card receiving machine is a self-service card receiving device, which is equipped with a card bucket and a card storage turntable. Before use, the staff will first store multiple smart cards that have completed personalized processing into the card hopper, and then the system will automatically store multiple smart cards in the card hopper into multiple card slots in the card storage carousel in turn ; When in use, the user only needs to place personal credentials such as an ID card in the identification area on the card receiving machine, and the system can automatically read the user's identity information and transfer the smart card corresponding to the user from the storage card carousel. Take it out, thereby realizing the user's self-service card collection. [0003] Among the...

AI Technical Summary

Problems solved by technology

[0004] In the design, on the one hand, in order to increase the card holding capacity of the card storage carousel, the thickness of the wall between the card slots is usually reduced as much as possible, so that the card storage carousel can distribute more card slots in the circumferential direction , but because the thickness of the smart card is small (usually 1mm), when the thickness of the wall between the card slots is set to be similar to the thickness of the smart card, it will cause great difficulty in processing the card slots. Specifically, (1) when using When the milling cutter is used for milling, since the width of the slot is about 1mm, the diameter of the milling cutter must be less than or equal to 1mm. When using a 1mm milling cutter for milling, on the one hand, the milling feed is small and the feed speed is relatively fast. slow, resulting in low processing efficiency and high cost of the turntable. On the other hand, when the feed rate is large or the feed speed is fast, it is easy to cause the phenomenon of knife breakage; (2) when the storage card turntable is manufactured by casting At the same time, due to the small width of the card slot and the airtight arrangement on the storage card turntable, it is difficult to open the mold and the cost is extremely high; And cracking occurs; and the groove width of 1mm will reduce the fluidity during pouring, so that cracks, bubbles and other problems will appear in the deposit card turntable after pouring, reducing the pass rate and performance of the product
