Problems solved by technology

[0002] The current usage of SIM cards is very large, with over 100 million pieces used in the civil communication industry each year. Traditional SIM cards are packaged with a chip on a card base. Customers only need to break off the small card after purchasing the SIM card. , inserted into the mobile phone for use, and the rest of the card base is discarded, so the utilization rate of the card base is not high, causing a lot of waste. At the same time, a large number of domestic and foreign customers in modern society have a demand for multi-chip SIM cards. Starting from this, we propose to package multiple chips on the base of a SIM card while reducing the occupancy rate of the device on the site

Embodiment Construction

[0034] The present invention will be further described below according to the accompanying drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.

[0035] Such as figure 1 with figure 2 Shown, a kind of SIM card manufacturing method of one, two, four chips comprises the following manufacturing steps:

[0036] S1: SIM card slot milling process; including a large slot milling station and two small slot milling stations, the SIM card is transported from the conveyor line to the large slot milling station, and the SIM card is milled into a large slot. After the slot is processed, it enters the large slot cleaning station. The large slot cleaning station cleans the large slot with a brush. After the large slot cleaning is completed, the SIM card is transported to two small slot milling stations, and the SIM card is milled in two small slots. Groove treatment, after the two small grooves are finished, enter the small groove cleani...

Abstract

The invention discloses a one-chip, two-chip and four-chip SIM card manufacturing method, and the method comprises the following steps: S1, SIM card groove milling flow; S2: chip packaging flow; S3: index dial corner conveying cooling flow; S4, SIM card punching flow. The method enables the installation length of the whole conveying line to be smaller through the corner conveying of an index dial,and achieves the cooling of a card welded with a chip through the rotation of the index dial, thereby reducing the cooling segment of the conveying line. Moreover, the method also achieves the cornerconveying and cooling of cards. SIM card manufacturing equipment is used for the manufacturing of different types of cards. The method is simple in manufacturing process, is convenient, is high in efficiency, achieves the multiple purposes, and reduces the installation of equipment.

Description

technical field [0001] The invention relates to the manufacture of SIM cards, in particular to a method for making SIM cards with one, two or four chips. Background technique [0002] The current usage of SIM cards is very large, with over 100 million pieces used in the civil communication industry each year. Traditional SIM cards are packaged with a chip on a card base. Customers only need to break off the small card after purchasing the SIM card. , inserted into the mobile phone for use, and the rest of the card base is discarded, so the utilization rate of the card base is not high, causing a lot of waste. At the same time, a large number of domestic and foreign customers in modern society have a demand for multi-chip SIM cards. Starting from this, we propose to package multiple chips on the card base of a SIM card while reducing the occupancy rate of the device on the site. Contents of the invention [0003] The purpose of the present invention is to provide a kind of...
