Detailed Description

The application provides a seal card cabinet convenient to take and a working method thereof, and aims to make the purposes, the technical scheme and the effects of the application clearer and more definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The application discloses a seal card rack convenient to take, as shown in the general structure diagram of fig. 1, include a vertical fixed axle 1 of placing, the axle center of a cylindricality gyration subassembly is inserted to fixed axle 1, gyration subassembly includes a rotatory rim plate 6, and through rotatory rim plate 6, accept the drive of an outside actuating source and around fixed axle 1 is rotatory.

The specific structure of the swivel assembly is shown in fig. 2, and is a cylindrical structure formed by a plurality of layers of horizontally arranged carrier plates 2 which are serially fixed by at least one vertically arranged connecting rod 8, wherein the connecting rod 8 is preferably arranged at the outer periphery of the carrier plate 2.

The carrying discs 2 are of disc-shaped structures, a circle of guide rails 3 arranged along the radial direction are uniformly arranged on the carrying discs 2 of each layer along the circumferential direction, and (only part of the guide rails 3 are marked in fig. 1), at most one drawer box 4 is slidingly matched on each guide rail 3, and one seal card 44 is usually stored in one drawer box 4, namely, the two seal cards are in one-to-one correspondence. Of course, in some special cases, for example, where a large company has multiple seal cards 44, all of the seal cards of that company may be stored in one drawer box 4, so long as the search is not affected. The rotating disc 6 is also horizontally arranged and coaxial with the cylindrical structure.

In a preferred embodiment, the cylindrical side of the rotary disk 6 is provided with a toothing 61 which can engage or otherwise cooperate with the drive source, for example an external gear with a power source or an external driving rack ring with a power source, which is driven and rotated as required to rotate the turntable assembly, the drive source preferably being provided by a stepper motor, i.e. a rotary stepper motor is used to drive the rotary disk 6 in rotation via the external gear.

In the embodiment shown in fig. 1 and 2, the swivel assembly is formed of 9 evenly distributed carrier discs 2, while the rotating disc 6 is arranged at the bottom of the swivel assembly, and preferably the bottom of the rotating disc 6 is further provided with a plurality of rollers, so that the swivel assembly is easier to rotate circumferentially. Of course, the rotary wheel 6 may be disposed in any position of the center axis of the swivel assembly in theory, as long as it remains concentric and perpendicular to the center axis.

When the revolving assembly is mounted on the fixed shaft 1, the bearing disc 2 is axisymmetrically arranged around the fixed shaft 1, that is, the circle center of the bearing disc 2 is substantially coincident with the circle center of the fixed shaft 1, and the fit between the fixed shaft hole in the center of the bearing disc 2, into which the fixed shaft is inserted, and the fixed shaft is slightly clearance fit, so that when the revolving assembly rotates circumferentially, the bearing disc 2 can rotate relative to the fixed shaft 1, and the radial displacement between the bearing disc 2 and the fixed shaft is not too large.

On the carrier plate 2, the angle difference between two adjacent guide rails 3 and the rotation step length of the rotation stepping motor should be matched, so that each step of rotation of the rotation stepping motor causes the guide rail 3 to rotate to the position of the next guide rail. Of course, it is also possible to set up as: each fixed few rotations of the rotary stepper motor result in a rotation of the rail 3 to the position of the next rail.

The correspondence between the seal card and the drawer box 4 storing the seal card is already input into a control system of the seal card cabinet when the seal card is put into the drawer box 4, so that when a certain seal card needs to be searched, only the information of the seal card needs to be searched is input into the control system, the control system can automatically search a database storing the information, find the number of the drawer box 4 storing the seal card, and further determine the position of the drawer box 4. The number of the drawer box 4 can be directly corresponding to the number of layers of the bearing disc 2 where the drawer box is positioned and the number of the guide rail 3 where the drawer box is positioned one by one.

For example, a certain drawer box 4 is located on the 5 th guide rail of the fourth layer of carrying disc, the number of the drawer box 4 can be coded into 0405, and when the seal card is stored in an operation mode, the seal card of a certain mechanism AAA is placed in the drawer box 4, and the corresponding relation information such as the AAA-0405 word can be stored in the database. Thus, when the operator inputs the information of the seal card to be searched through the terminal 7 of the control system, preferably a touch screen arranged on the seal card cabinet, the control system automatically searches the database in the control system and reads the position of the drawer box where the seal card of the mechanism AAA to be searched is located is 0405, namely, the seal card is identified to be located in the drawer box on the 5 th guide rail of the fourth layer bearing disc.

In the invention, referring to fig. 5-7, the seal card 44 is provided with an RFID electronic tag 45, an RFID radio frequency antenna 11 is arranged above each layer of carrying disc 2 on the frame of the cabinet, the RFID radio frequency antenna 11 faces the moving path of the drawer box 4 along with the rotation of the carrying disc 2, when the carrying disc 2 rotates, the seal card 44 rotates together with the drawer box 4, and the RFID radio frequency antenna 11 of each layer receives the information of the RFID electronic tag 45 of the seal card 44 in the drawer box 4 at any time. The frame of the cabinet is also provided with a reader-writer 10, for example, a four-channel ultrahigh frequency reader-writer, the RFID radio frequency antenna 11 of each layer feeds information on the received seal card 44 back to the reader-writer 10, and the reader-writer 10 recognizes the information on the seal card 44 and reads and writes the information, so that the flowing condition of all the seal cards 44 in the whole cabinet can be monitored in real time, and an automatic checking function is realized.

At the same time, a push-pull mechanism 5 is arranged above the carrying tray 4 of each layer. The push-pull mechanism 5 is preferably arranged in a central position of the carrier plate 4, for example in the embodiment of fig. 1, the push-pull mechanism 5 is fixedly arranged on the stationary shaft 1.
