An upper storage compartment, a middle storage compartment, and a lower storage compartment are arranged in the accommodation opening from top to bottom.

[0004] However, in the prior art, there is a lack of means for limiting the stored materials, and it is still impossible to move for picking and placing materials, there is no corresponding material control, the picking and placing time of materials cannot be recorded, and material control cannot be guaranteed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a trolley cabinet device for intelligent storage and positioning of materials, so as to solve the problems existing in the prior art.

[0006] The purpose of the utility model is achieved as follows: A trolley cabinet device for intelligent storage and positioning of materials, comprising:

[0007] A movable cabinet body, on the inner sidewall of which several spaced-apart supporting pieces are fixed from top to bottom. The supporting pieces form storage positions for storing materials. The supporting pieces are inclined downward based on the entrance side. Several RFID sensing modules are also fixed on the inner sidewall of the cabinet body, corresponding one by one to the supporting pieces. The RFID sensing modules are used to read the RFID tag information on the materials and identify whether the materials are placed in the storage positions;

[0008] A power distribution control bin, which is fixedly connected to the cabinet body and internally provided with an electric control unit. The RFID sensing modules are electrically connected to the electric control unit;

Detailed Embodiments

[0021] The following will combine the attached drawings in the embodiments of the present utility model Figure 1-7, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1-3 shown, a trolley cabinet device for intelligent storage and positioning of materials is proposed. It is applicable to the semiconductor field and is used to store materials with RFID tag information. The materials involved are wafer boxes with RFID tag information, and there are wafers in the wafer boxes. The device includes:

[0023] A movable cabinet 1, with rollers installed at its bottom, which is equivalent to a small trolley. A number of supporting pieces 10 for materials are fixedly arranged on the inner side wall of the cabinet 1 at intervals from top to bottom. The supporting pieces 10 form storage positions for storing materials. A number of RFID sensing modules 9 that are in one-to-one correspondence with the supporting pieces 10 are also fixedly arranged on the inner side wall of the cabinet 1. The RFID sensing modules 9 are used to read the RFID tag information on the materials and identify whether the materials are placed in the storage positions;

[0024] A power distribution control bin 6, which is fixedly connected to the cabinet 1 and internally provided with an electric control unit and a gateway unit. The RFID sensing module 9 is electrically connected to the electric control unit;

[0025] A display 8 for displaying material storage information, which is electrically connected to the electric control unit and is installed on the upper side of the cabinet 1.

[0026] Among them, one side of the above-mentioned cabinet 1 is set as an opening and faces the entrance side of the supporting piece 10. A cabinet door 2 for opening and closing the opening is rotatably connected to the cabinet 1.

[0027] As Figure 6 shown, the supporting piece 10 is inclined downward by 5° based on the entrance side, or other appropriate angles. After the materials are placed on the supporting piece 10, the materials will slide in the direction of the inside of the cabinet 1 to the low-end position of the supporting piece 10. The inclined supporting piece 10 combined with the position-limiting function of the cabinet door 2 can prevent the materials from sliding forward or even sliding out of the cabinet 1 during the pushing process. And, the above-mentioned RFID sensing module 9 is at the lowest position of the supporting piece 10. When placing the materials, the materials are placed on the supporting piece 10, and the materials slide in the direction of the inside of the cabinet 1 to the low-end position of the supporting piece 10, which can make the RFID tag on the materials form an induction with the RFID sensing module 9. The electric control unit processes the induction signal of the RFID sensing module 9 and finally outputs it to the display 8. The display 8 is used to display the storage status information of the storage position and update the storage information in a timely manner. The storage information will be synchronized and uploaded to the network system in a timely manner for the convenience of the operators to check in a timely manner.

[0028] The working process or principle is described as follows:

[0029] I. Taking out materials

[0030] 1. The operator takes out materials from the designated trolley cabinet device;

[0031] 2. The RFID sensing module 9 at the taking-out position is triggered and reads the card;

[0032] 3. The ID information of the trolley cabinet device, the taking-out position information, and the RFID tag information of the material box are transmitted to the material management system of the computer;

[0033] 4. The system saves and updates the material information system, sends data to the display 8 of the trolley cabinet device, and the display 8 shows the material position information of the current trolley cabinet device.

[0034] II. Putting back materials

[0035] 1. The operator puts back materials into the designated trolley cabinet device;

[0036] 2. The RFID sensing module 9 at the putting-back position is triggered and reads the card;

[0037] 3. The ID information of the trolley cabinet device, the taking-out position information, and the RFID tag information of the material box are transmitted to the material management system of the computer;

[0038] 4. The system saves and updates the material information system, sends data to the display 8 of the trolley cabinet device, and the display 8 shows the material position information of the current trolley cabinet device.

[0039] From the above working process, it can be seen that the device of this embodiment has the functions of intelligent storage positioning and mobile material taking.

[0040] As Figure 4 , 5 shown, a pair or more pairs of limiting strips 11 for limiting the placement position of materials are fixed on the upper surface of the above-mentioned support piece 10. The limiting strips 11 extend along the material putting-in direction. For each pair of limiting strips 11, the distance between each pair of limiting strips 11 matches the size specification of the corresponding material, and the corresponding material is limited to the position between each pair of limiting strips 11. The two sides of the material can respectively lean against the corresponding two limiting strips 11 movably.

[0041] The number of the above-mentioned limiting strips 11 can be multiple pairs (the number of the limiting strips 11 can be unlimited, and any improvement is within the protection scope of this patent). A pair of limiting strips 11 with a smaller distance is located between a pair of limiting strips 11 with a larger distance, and the outer limiting strips 11 are thicker than the inner limiting strips 11, so as to limit materials of different specifications.

[0042] As Figure 1As shown in the figure, as a structural optimization solution, the above-mentioned power distribution control bin 6 is fixedly connected to the bottom of the cabinet body 1.

[0043] As a preferred anti-static solution, a plurality of conductive casters 7 for rolling and supporting the ground and used to conduct the static electricity generated by friction are rotatably connected to the bottom of the above-mentioned power distribution control bin 6. The conductive casters 7 (and grounding chain) are used to conduct the static electricity generated by friction. The number of the conductive casters 7 is not limited here. By increasing the spacing of the conductive casters 7, the problem of tipping during the pushing process of the trolley cabinet device can be prevented.

[0044] As Figure 1-3 As shown in the figure, as an optimized opening and closing solution, one side of the above-mentioned cabinet door 2 is rotatably connected to the cabinet body 1, and a locking mechanism 4 is installed on the side wall of the cabinet body 1. When the cabinet door 2 is in the closed state, the other side of the cabinet door 2 is locked by the locking mechanism 4. The locking mechanism 4 can be set as a stainless steel buckle (conventional mechanical component). When locking, the stainless steel buckle hooks the hook plate fixed to the other side of the cabinet door 2.

[0045] A door handle 3 is installed on the outer surface of the above-mentioned cabinet door 2 to facilitate the operator to open and close the cabinet door 2.

[0046] In order to facilitate the pushing of the entire cabinet body 1, a trolley handle 5 is fixedly connected to the side wall of the cabinet body 1. The operator can hold the trolley handle 5 to push the cabinet body 1 to move.

[0047] As Figure 7 As shown in the figure, as a project setting solution, a power input interface 12, a network interface 13 and a power control button 14 electrically connected to the electric control unit are provided at corresponding positions of the power distribution control bin 6. The power input interface 12 can be connected to a power supply. The network interface 13 is used to connect to a dedicated network (MES or WMS system) so as to form a storage information interaction relationship with the system. The power control button 14 is used for turning on / off.

[0048] In this embodiment, through network and software control, the intelligent storage positioning and mobile material picking of materials are realized. The display 8 displays the information of each storage location in the cabinet body 1 in real time, and transmits the material picking and placing information to the MES or WMS system in real time. After the network is restored after being disconnected, there is a prompt for the material change alarm, realizing intelligent management of storage and saving management costs.
