When the card performs a card storing task, one end of the card is contacted with the guide separating piece of the inlet and the outlet, and then enters the card storing groove under the guide action of the guide separating piece of the inlet and the outlet, so that the card storing task is completed; when the card needs to be taken out, the related card taking piece applies an outward pulling force to the card, and the card is taken out. Although the guide is only present in the guide partition section of the card tray, it functions as a guide and support for the cards, since it is capable of separating the cards on the one hand, and thus functions as the groove wall of the original accommodating groove on the other hand. In view of the processing difficulty, (1) when the card storage turntable is processed by adopting a milling method, the guide part and the non-guide part (the non-guide part is communicated with each other and occupies most of the accommodating grooves) can be processed respectively, wherein when the non-guide part is processed, only one large accommodating groove is required to be milled in the processing, and the size of the large accommodating groove is far larger than that of the small accommodating groove, specifically, when a guide partition piece is arranged in one large accommodating groove and divides the accommodating groove into two small accommodating grooves, the size of the accommodating groove is the size of two 1mm accommodating grooves plus the size of one 1mm groove wall, namely, the size is about 3mm; when a large accommodating groove is internally provided with two guide separating pieces to separate the accommodating groove into three clamping grooves, the size of the accommodating groove is three clamping grooves with the size of 1mm plus the size of two groove walls with the size of 1mm, namely, the size is about 5mm, when milling is carried out on the accommodating groove with the size of 5mm, a milling cutter with the size of 5mm is adopted instead of the original milling cutter with the size of 1mm, and compared with the milling cutter with the size of 1mm, the milling cutter with the size of 5mm is greatly improved due to the multiplication of the feeding amount and the feeding speed of the cutter during processing, and the phenomenon of cutter breakage rarely occurs, so that the processing efficiency is high and the processing effect is good; the guide part is continued to be milled by a milling cutter with the length of 1mm, and the time consumption is low because the part has a short groove length (most of the memory card groove is concentrated on the extension section part of the containing groove).
In summary, the card storage turntable in the scheme has the unique structural structure, so that the processing difficulty is greatly reduced, the processing speed is obviously improved, and the card storage turntable has extremely important significance for the production and the manufacture of products.
(2) When the grinding tool injection molding mode is adopted to produce and manufacture the memory card turntable, the difficulty in processing the memory card groove is greatly reduced due to the arrangement of the guide separating piece, so that on one hand, when the grinding tool of the memory card turntable is subjected to die opening, the die opening difficulty is greatly reduced, and the die opening cost is also greatly reduced; on the other hand, when the grinding tool is subjected to injection molding, because the groove width of the accommodating groove is large (the working principle of the milling process can know that the width of the accommodating groove is 3mm or more), when pouring and filling are performed, the liquid fluidity can be increased, so that the filling rate can be increased, the problem that the card storage turntable after injection molding cannot be insufficient in filling, cracked, bubble and the like can be solved, the turntable after injection molding has the advantages of high precision and good quality, and because the interval between the male die and the female die in the die is increased, the cracking is not easy to occur due to accidental collision.

1. According to the card storage turntable, the large accommodating groove is divided into the small card storage grooves by additionally arranging the guide separating pieces at the inner sides of the inlet and the outlet of the accommodating groove, so that only one large accommodating groove is needed to be washed out during processing, and as the groove width of the large accommodating groove is three times or more than that of the small accommodating groove, milling can be performed by adopting a milling cutter with a larger diameter, and compared with the milling cutter with a smaller diameter, the feeding amount and the feeding speed of the milling cutter during processing are multiplied, so that the milling efficiency is greatly improved, and the phenomenon of cutter breakage is less caused, so that the milling efficiency is high and the milling effect is good.
2. When the grinding tool injection molding mode is adopted to produce and manufacture the memory card rotating disc, on one hand, when the grinding tool of the memory card rotating disc is subjected to die opening, the die opening difficulty is greatly reduced, and the die opening cost is also greatly reduced; on the other hand, when the grinding tool is subjected to injection molding, because the groove width of the accommodating groove is large (the working principle of the milling process can know that the width of the accommodating groove is 3mm or more), when pouring and filling are performed, the liquid fluidity can be increased, so that the filling rate can be increased, the problem that the card storage turntable after injection molding cannot be insufficient in filling, cracked, bubble and the like can be solved, the turntable after injection molding has the advantages of high precision and good quality, and because the interval between the male die and the female die in the die is increased, the cracking is not easy to occur due to accidental collision.
3. The guide separating piece is additionally arranged, so that the difficulty in processing the card storage groove is greatly reduced, conditions are created for processing double-sided grooves of the turntable, and after the double-sided processing is carried out on two end surfaces of the turntable, the large turntable can be formed by combining the turntable with other turntables, so that the card storage capacity of the turntable can be greatly increased, and the whole turntable has the advantage of compact structure.

When in use, the tooth grooves 8 are meshed with the card supporting belt 10, and the rotation of the turntable is realized in a mode of driving the tooth belts to rotate through the driving mechanism, so that the normal card storing and taking task can be carried out. The advantage of this setting lies in, for the mode that drives the connecting axle through the motor and rotates and then drive carousel pivoted, this transmission mode through tooth area tooth's socket 8 on the one hand can save the axial space of the neck card machine that the memory card carousel corresponds for the overall arrangement of neck card machine can be reasonable, on the other hand, because between tooth's socket 8 and the memory card slot 5 one-to-one, consequently whenever the tooth of tooth area moves from tooth's socket 8 to another tooth's socket 8 adjacent, the memory card carousel rotates the angle of a memory card slot 5 promptly, the card import and export 4 on the neck card machine is cut from the alignment of last memory card slot 5 to the alignment of next memory card slot 5, thereby accomplish the switching task between two adjacent memory card slots 5 on the memory card carousel after, and this switching has the advantage of precision height.
The working principle of the invention is as follows:
The card storing rotary table of the present invention can be regarded as dividing a large receiving slot 2 into a plurality of small card storing slots 5 for storing a smart card by adding a guide partition 3 to the inner side of the inlet and outlet of the receiving slot 2, each small card storing slot 5 including a card inlet and outlet 4 and a space in which the card inlet and outlet 4 extends inside the receiving slot 2. When the card 9 performs a card storing task, one end of the card 9 is contacted with the guide separating piece 3 of the inlet and the outlet, and then enters the card storing groove 5 under the guide action of the guide separating piece 3 of the inlet and the outlet, so that the card storing task is completed; when the card 9 needs to be taken out, the card 9 is taken out by exerting an outward pulling force on the card 9 by the relevant card taking member. Although the guide is only provided in the guide partition section of the card tray, it is functionally equivalent to the groove wall of the original storage groove 2 because it is capable of partitioning the card 9 and guiding and supporting the card 9. In view of the processing difficulty, (1) when the card storage turntable is processed by adopting a milling method, the guide part and the non-guide part (the non-guide part is communicated with each other and occupies most of the accommodating groove 2) can be processed respectively, wherein when the non-guide part is processed, only one large accommodating groove 2 is required to be milled in the processing, and the size of the large accommodating groove 2 is far larger than that of the small accommodating groove 5, specifically, when one large accommodating groove 2 is provided with one guide partition piece 3, the accommodating groove 2 is divided into two small accommodating grooves 5 by the guide partition piece 3, and the size of the accommodating groove 2 is the size of the two accommodating grooves 5 with the size of 1mm plus the size of the groove wall with the size of 1mm, namely, the size is about 3mm; when two guide separators 3 are arranged in one large accommodating groove 2 to divide the accommodating groove 2 into three memory card grooves 5, the size of the accommodating groove 2 is three 1mm memory card grooves 5 plus the size of two 1mm groove walls, namely, the size is about 5mm, when milling is carried out on the 5mm accommodating groove 2, a 5mm milling cutter is adopted instead of the original 1mm milling cutter, and compared with the 1mm milling cutter, the 5mm milling cutter has the advantages that the feeding amount and the feeding speed of the cutter are multiplied during processing, so that the milling efficiency is greatly improved, the cutter breakage phenomenon rarely occurs, the processing efficiency is high, and the processing effect is good; the guide part is continued to be milled by a milling cutter with the length of 1mm, and the time consumption is low because the part has a short groove length (most of the memory card groove 5 is concentrated on the extension part of the accommodating groove 2).
In summary, the card storage turntable in the scheme has the unique structural structure, so that the processing difficulty is greatly reduced, the processing speed is obviously improved, and the card storage turntable has extremely important significance for the production and the manufacture of products.
(2) When the grinding tool injection molding mode is adopted to produce and manufacture the memory card turntable, the difficulty in processing the memory card groove 5 is greatly reduced due to the arrangement of the guide partition piece 3, so that on one hand, when the grinding tool of the memory card turntable is subjected to die opening, the die opening difficulty is greatly reduced, and the die opening cost is also greatly reduced; on the other hand, when the grinding tool is injection molded, since the groove width of the accommodating groove 2 is large (as known from the working principle of the milling process, the width of the accommodating groove 2 is 3mm or more), when pouring and filling, the liquid fluidity is increased, so that the filling rate is increased, and the problem of insufficient filling, cracks, bubbles and the like of the card storage turntable after injection molding can be avoided, so that the turntable after injection molding has the advantages of high precision and good quality, and the turntable is not easy to crack due to accidental collision because of the increase of the distance between the male die and the female die in the die.
A processing method of a card storage turntable comprises the following steps:
(1) Taking a square blank, placing the square blank on a milling machine or a numerical control machining center, and clamping and fixing the bottom of the square blank;
(2) Milling a disc boss on the upper part of the square blank by using a milling cutter, wherein the appearance and the size of the disc boss are the same as those of the card storage turntable, and milling a central shaft hole with the same depth as that of the boss in the center of the boss;
(3) After the blank is turned upside down, clamped and fixed, milling a square base above the disc boss at the moment, so as to form a semi-finished product of the card storage turntable;
(4) Then, transferring the processed disc-shaped blank to a gear hobbing machine, clamping and fixing the disc-shaped blank, and milling teeth on the outer circular surface of the disc-shaped blank by using the gear hobbing machine;
(5) Transferring the disc-shaped blank after finishing milling teeth to a milling machine or a numerical control machining center, clamping and fixing the disc-shaped blank in a mode that a pin shaft is matched with a tooth slot 8 on an outer cylindrical surface, and then milling grooves on the end face of a turntable by using a milling cutter, wherein the groove milling task is carried out step by step and comprises the following steps: a. milling grooves on the guide partition piece section of the disc-shaped blank by using a milling cutter with the diameter of 1 mm; b. when the non-guiding partition piece section on the memory card slot is milled, the non-guiding partition piece section comprises a milling slot close to the circle center end and far away from the circular section, wherein a milling cutter of No. 2.5mm is adopted when the non-guiding partition piece section is milled close to the circle center section, and a milling cutter of No. 3mm is adopted when the non-guiding partition piece section is far away from the circular section.
(6) And after finishing the groove milling task, forming the finished product card storage turntable.
