Description

Technical Field

[0001] The present invention relates to the field of intelligent storage technology, and in particular to an intelligent standard product storage management cabinet. Background Art

[0002] The intelligent standard product storage and management cabinet is a device that integrates advanced technology. It is used to store and manage standard products efficiently and safely, achieve precise control, real-time monitoring and convenient management of standard products, ensure that standard products are stored in the best environment, and prevent deterioration or failure. Users can perform access operations through the touch screen or remote operation interface. The system will automatically record the time, quantity and other information of each access for easy traceability and management. The intelligent standard product storage and management cabinet also has an alarm function. When the environmental parameters are abnormal or the storage conditions are not up to standard, an alarm will be issued in time to ensure the safety and reliability of the standard products.

[0003] A Chinese patent with publication number CN220333743U discloses a three-dimensional lifting intelligent storage cabinet, including a cabinet body and a base. A delivery port is opened on the surface of the cabinet body, an operation panel is fixedly arranged on the surface of the cabinet body near the delivery port, and a buffer slope is fixedly arranged at the lower end of the cabinet body. The third motor rotates to drive the first screw rod to rotate, thereby driving the sliding block to move horizontally, and then the first motor rotates to drive the first gear to rotate, so that the second screw rod rotates, so that the lifting platform can be adjusted to the same position as the rolling component that needs to pick up the goods, and the conveyor belt is started to push the goods out, which can prevent the user from being injured when the user wants to store and access heavier goods on the high shelves due to the heavy goods falling.

[0004] During the storage process of the three-dimensional lifting intelligent storage cabinet of the above-mentioned patent, the materials stored inside the beam are not completely wrapped inside the device, and the front end of the beam is exposed. The failure to achieve complete wrapping will result in the inability to independently and accurately control the temperature. Only one temperature adjustment can be achieved in an intelligent storage cabinet. During the storage process, the storage and retrieval frequencies of different stored items are different. It is inefficient to simply place different items one by one and then frequently take out a certain item. Summary of the invention

DETAILED DESCRIPTION

[0048] The present invention is further described below in conjunction with specific embodiments.

[0049] Example 1: Figure 1 As shown, the intelligent standard product storage management cabinet of this embodiment includes a shell 1, and an entrance 4 is provided in the middle of the front end of the shell 1, through which items can be taken out and placed, and an operation screen 5 is provided on one side of the front end of the shell 1, through which the device can be operated, and the system built into the operation screen 5 can also realize the storage of intelligent items;

[0050] Among them, Figure 5 and Figure 6 As shown, the interior of the housing 1 is laterally distributed with a first area 20, a second area 21 and a third area 22. The three areas are spaced at different distances from the entrance 4. Different distances correspond to different usage frequencies. The first area 20 for storing materials with high usage frequency is close to the entrance 4, and the third area 22 for storing materials with low usage frequency is far away from the entrance 4. Fixed frames 13 are arranged on both sides of the interior of the second area 21 and the third area 22, and a fixed frame 13 is arranged on the other side of the interior of the first area 20. A movable mechanical clamping arm 19 is arranged in the middle of the interior of the housing 1. The mechanical clamping arm 19 can slide laterally in the middle of the housing 1 to take out different materials stored in the first area 20, the second area 21 and the third area 22.

[0051] A mechanical clamping arm is mentioned in the Chinese patent with the announcement number CN221271198U. The mechanical clamping arm in the present application is the same as the mechanical clamping arm in the Chinese patent with the announcement number CN221271198U, and has the same function. Moreover, the technical problem to be solved by the present application has nothing to do with the clamping method and the external structure of the mechanical clamping arm. Therefore, in the present application, the mechanical clamping arm 19 is not described too much. A slide rail is provided at the upper end of the inner part of the housing 1. Both sides of the mechanical clamping arm 19 are embedded in the inner part of the slide rail and can slide horizontally in the middle of the housing 1 and approach the first area 20, the second area 21 and the third area 22.

[0052] In addition, if Figure 2 and Figure 3 As shown, in order to store the materials stored in the first area 20, the second area 21 and the third area 22 independently and protect the stored materials, a storage rack 17 is arranged inside the fixed frame 13 toward the middle position of the housing 1, the outside of the storage rack 17 is slidably connected with the inside of the fixed frame 13, and rollers 15 are arranged at the four corners of the lower end of the storage rack 17. The rollers 15 are driven to rotate and drive the storage rack 17 to actively extend out of the fixed frame 13 laterally, and the extension of the corresponding storage rack 17 can be matched with the clamping of the mechanical clamping arm 19 to realize the removal and placement of the materials;

[0053] During the actual storage process, different materials will be stored in the first area 20, the second area 21 and the third area 22. Different storage materials require different ambient temperatures during the storage process. Space is reserved on the other side of the first area 20 for placing two longitudinally distributed cooling devices 8. A three-way air valve 10 is sealed on one side of the outside of the fixed frame 13. The upper and lower ends of the three-way air valve 10 corresponding to all fixed frames 13 are connected by pipes 9. The two pipes 9 are respectively connected to the air outlet positions of the two cooling devices 8. After the mist mixture generated by the cooling device 8 is blown by the fan, the mist mixture is directly sent into the fixed frame 13 by the pipe 9. Different temperatures can be transmitted to different positions through the two cooling devices 8 and the two pipes 9 to meet different material storage requirements.

[0054] The cooling device 8 sucks in and compresses the low-temperature and low-pressure gaseous refrigerant through the compressor inside the cooling device 8, so that its temperature and pressure rise sharply to form a high-temperature and high-pressure gas. The high-temperature and high-pressure refrigerant enters the condenser and is forced to dissipate heat through the fan. The refrigerant gradually liquefies and releases heat to the outside air. In the present application, the heat is actively discharged through the mesh port on the other side of the front end of the shell 1. The liquid refrigerant flows through the expansion valve. Due to the sudden reduction in cross-sectional area, the pressure drops suddenly. Part of the liquid refrigerant is converted into a low-temperature and low-pressure mist mixture. After the mist mixture is transmitted to the inside of the fixed frame 13 through the pipeline 9, the mist mixture flows in the fixed frame 13 and contacts the heat in the gas inside the fixed frame 13. After that, it is completely vaporized and the temperature inside the fixed frame 13 is reduced;

[0055] The refrigerant is compressed by a compressor and condensed, and throttled after condensation, and the mist mixture is controlled by the intensity of throttling, and the mist mixture is controlled to control the cooling intensity, and then the mist mixture is transmitted to the cooling position. This cooling method is a conventional technology and is common knowledge. In addition, the present application does not invent the cooling method of the cooling device 8, but only improves the cooling area, so there is no excessive description of the internal structure of the cooling device 8.

[0056] In order to facilitate the adjustment of the temperature in the fixing frame 13, Figure 4 and Figure 7 As shown, an electronic valve 12 is provided between the pipeline 9 and the three-way gas valve 10. The transmission of the low-temperature gas can be limited by closing the electronic valve 12. After the two different temperatures are transmitted inside the pipeline 9 through the two cooling devices 8, the temperature that finally enters the fixed frame 13 is adjusted by opening the electronic valve 12.

[0057] Among them, a sheet-shaped second baffle 16 is provided at the middle position of the storage rack 17 toward the housing 1, and the storage rack 17 is welded and fixed to the second baffle 16. After the storage rack 17 is completely stored in the fixed frame 13, the second baffle 16 will completely fit the outside of the fixed frame 13, so that a relatively air-free environment is formed inside the fixed frame 13, so that the low-temperature gas flowing in from the three-way gas valve 10 can be retained in the corresponding fixed frame 13, and the low-temperature gas is restricted, so that the gas temperatures inside two adjacent fixed frames 13 can be prevented from affecting each other;

[0058] In order to allow the low temperature transmitted from the three-way gas valve 10 to the inside of the fixed frame 13 to be fully and efficiently distributed inside the fixed frame 13, a concave connecting groove 14 is longitudinally arranged inside the storage rack 17 toward the position of the three-way gas valve 10. The concave connecting groove 14 allows the gas to fully flow into different positions inside the fixed frame 13;

[0059] In order to facilitate the transmission of the low-temperature gas to the interior of the fixed frame 13 again after the storage rack 17 is reset, a connecting pipe 11 is provided in the connecting groove 14 toward the three-way gas valve 10, and the connecting pipe 11 is sealed and connected to the storage rack 17. When the storage rack 17 is reset, the connecting pipe 11 will be embedded in the outside of the gas outlet end of the three-way gas valve 10, and the three-way gas valve 10 will be sealed and connected to the connecting pipe 11. The low-temperature gas can be transmitted again through the connection between the connecting pipe 11 and the three-way gas valve 10.

[0060] To further understand the content of the present invention, please refer to Figure 8 , this embodiment provides the following technical solutions:

[0061] The intelligent standard product storage management cabinet also includes an intelligent storage system composed of a data entry module, a data editing module, a data position recording module, a storage time recording module, a retrieval number recording module, a re-storage interval recording module, a position distribution calculation module and a driving module. The intelligent storage system is built into the operation screen 5;

[0062] Among them: Data entry module: used to manually input item data, bind new items to RFID tags, establish a mapping relationship between RFID tags and item data, enter the corresponding item name, specifications and department in the item data, and replace manual registration with RFID scanning to improve input efficiency;

[0063] Data editing module: used to support the modification of stored item data. It can change the item name, specifications and department corresponding to the stored items, record the modification history, ensure the real-time accuracy of information such as item specifications and responsible persons, and meet the traceability requirements for electronic records;

[0064] Storage time recording module: used to accurately record storage time. The recorded storage time helps the calculation of the subsequent location distribution recording module and improves the accuracy of determining the item placement area. The unit is day. At the same time, the difference between two adjacent storage times can also be recorded and recorded. The calculation can be completed by subtracting the two recorded times and taking the absolute value of the value. The total storage time can also be obtained by adding the storage time of each time.

[0065] Removal times recording module: used to accurately record the number of times taken out. Each legal removal operation triggers the counter. The recorded number of times taken out helps the calculation of the subsequent location distribution recording module and improves the accuracy of determining the item placement area. The unit is times;

[0066] Re-deposit interval recording module: used to record the time difference between two consecutive deposits, remove the erroneous operation records of less than five minutes, and assist in determining the frequency of item use through the re-deposit interval recording module to assist in the calculation of the subsequent location distribution recording module, the unit is day;

[0067] Position distribution calculation module: used to calculate the area where the mechanical gripping arm 19 should place the gripped object by using the data recorded by the storage time recording module, the number of times of taking out the gripping module and the re-storage interval recording module in combination with the formula;

[0068] The formula used for the above calculation is:

[0069]

[0070] in, is the frequency weight coefficient, and its value is fixed at 0.6. is the number of times taken out;

[0071] is the time attenuation coefficient, and its value is fixed at 0.15. The total storage time recorded by the storage time recording module, through The frequency of withdrawal can be calculated;

[0072] is the interval sensitivity coefficient, the value is fixed at 0.25, is the time difference between two consecutive storages, For the storage times, The mean of the re-existence interval can be calculated;

[0073] is the location distribution value, through which the location of the item can be determined;

[0074] In the position distribution calculation module, the region division threshold of the first region 20 is P≥4.2, the region division threshold of the second region 21 is 2.8≤P<4.2, and the region division threshold of the third region 22 is P<2.8. The calculated P value corresponds to the region in which the range is met.

[0075] The calculation is performed by using the formula built into the location distribution calculation module in combination with the data recorded by the storage time recording module, the number of retrieval recording module and the re-storage interval recording module. After the calculation, the data is compared with the area division thresholds corresponding to the first area 20, the second area 21 and the third area 22. If the data is within the area division threshold, then the item corresponding to the data is placed in the area corresponding to the division threshold.

[0076] For example, the storage time recording module records that the total storage time of the item is 7 days, the retrieval times recording module records that the item is retrieved 21 times, and the storage time recording module records that the difference between two consecutive storage times is 2 days. Substitute the data into the formula From the calculation, we know that , and 2.32 meets the area division threshold of the third area 22, which is P < 2.8. Then, through the position distribution calculation module, when the item is placed for the 22nd time, it should be placed in the third area 22 away from the entrance 4;

[0077] For example, the storage time recording module records the total storage time of the item as 1 day, the retrieval times recording module records the retrieval times of the item as 10 times, and the storage time recording module records the difference between two consecutive storage times as 0.1 day. Substitute the data into the formula From the calculation, we know that , and 6.25 meets the area division threshold of the first area 20, which is P ≥ 4.2. Then, through the position distribution calculation module, it is calculated that when the item is placed for the 11th time, it should be placed in the first area 20 near the entrance 4;

[0078] When T>30 days, the decay rate slows down to avoid excessive punishment of short-term storage items, while the exponential function To achieve rapid decay, when G < 1 day, it is called frequent use of the item, giving it high added value;

[0079] Driving module: used to drive the mechanical gripping arm 19 to grab the items. When storing items, the data calculated by the position distribution calculation module is used to confirm in which area the items should be placed, and the items are grabbed by the mechanical gripping arm 19 and placed in the corresponding area. When taking out the items, according to the data recorded in the data position recording module, the mechanical gripping arm 19 is directly moved to the corresponding area to take out the corresponding stored items.

[0080] Data position recording module: It is used to record the data calculated by the position distribution calculation module after the driving module drives the mechanical clamping arm 19 to place the items, so as to facilitate the subsequent retrieval, improve the retrieval efficiency, and improve the speed and stability of the operation of the entire intelligent standard product storage management cabinet.

[0082] In order to continuously monitor the temperature inside the fixed frame 13, a first temperature sensor 18 is arranged on one side of the second baffle 16, and a temperature display screen 2 is arranged between the entrance and exit 4 and the operation screen 5. The temperature monitored by the first temperature sensor 18 can be displayed through the temperature display screen 2. An alarm light 3 is arranged on one side of the upper end of the temperature display screen 2. When the temperature monitored by the first temperature sensor 18 does not match the set range, an alarm is issued through the alarm light 3.

[0083] In order to reduce the influence of the external environment temperature on the temperature in the fixed frame 13 during the process of opening the entrance and exit 4, a second temperature sensor is provided on the outer side of the housing 1 near the entrance and exit 4, the operation screen 5 has a built-in control module, the first temperature sensor 18 and the second temperature sensor are electrically connected to the control module respectively, the cooling device 8 is electrically connected to the control module, and a temperature display screen 2 is provided between the entrance and exit 4 and the operation screen 5, and the temperature display screen 2 is used to display the cabinet temperature detected by the first temperature sensor 18 and the ambient temperature detected by the second temperature sensor;

[0084] Within a preset time interval, historical access data of stored items is analyzed to determine the estimated number of times the entrance and exit 4 is opened within the preset time interval; those skilled in the art can adjust the interval length of the preset time interval according to actual needs.

[0085] When the estimated opening times of the entrance and exit 4 within the preset time is less than the preset opening times threshold, it means that the number of accesses to the stored items within the preset time interval is small, and it is judged that the impact of the opening of the entrance and exit 4 on the temperature inside the cabinet can be ignored, then the fixed frame 13 is temperature-controlled based on the estimated recommended temperature; the preset opening times threshold is set by technical personnel in this field according to actual needs, the estimated recommended temperature is the middle temperature of the recommended temperature range, and the recommended temperature range is the storage temperature range of the stored items.

[0086] When the estimated opening times of the entrance 4 within the preset time is greater than the preset opening times threshold, the average opening duration of the items accessed in other adjacent times that are the same as the preset time interval is calculated, and the average ambient temperature within the average opening duration is calculated;

[0087] Obtain the real-time cabinet temperature value in the fixed frame 13, and draw the cabinet temperature change curve based on the preset time, calculate the temperature difference between the real-time cabinet temperature value in the fixed frame 13 and the average value of the ambient temperature, and calculate the influence of the temperature difference between the real-time cabinet temperature value in the fixed frame 13 and the average value of the ambient temperature on the curvature of the temperature change curve in the fixed frame 13;

[0088] When the real-time temperature value in the cabinet exceeds the preset temperature threshold or the curvature of the temperature change curve in the fixed frame 13 changes within a unit time beyond the preset temperature change threshold, the control module starts the cooling device 8 and issues an alarm through the alarm light 3.

[0089] The principle and effect of the above technical solution are as follows: by simultaneously monitoring the ambient temperature and the real-time cabinet temperature value in the fixed frame 13, the possible opening times of the entrance and exit 4 within the preset time interval are obtained by analyzing the historical data. If the number of times is small, it can be ignored. If the number of times is large, it is necessary to consider the impact of the opening of the entrance and exit 4 on the temperature in the fixed frame 13. The average opening duration is estimated in advance by referring to the historical data, and the average ambient temperature value within the period is calculated in combination with the current ambient temperature. Generally, the length of the preset time will not be very long, such as 30 minutes, or 1 hour. The ambient temperature change within this preset time will not be particularly large. Therefore, the ambient average temperature value can be used to reflect the ambient temperature situation. By calculating the temperature difference between the average ambient temperature and the real-time cabinet temperature value in the fixed frame 13, the possible impact of the external environment temperature on the temperature in the fixed frame 13 can be grasped. The temperature difference The larger the value is, the greater the impact of opening the entrance and exit 4 on the temperature in the fixed frame 13. By analyzing the impact of the temperature difference between the real-time cabinet temperature value in the fixed frame 13 and the average ambient temperature on the curvature of the temperature change curve in the fixed frame 13, the necessity of adjusting the temperature in the fixed frame 13 can be judged in advance. When this impact is greater, it means that the temperature in the fixed frame 13 may soon reach the preset temperature threshold and needs to be adjusted. Therefore, when the curvature of the temperature change curve in the fixed frame 13 changes more than the preset temperature change threshold per unit time (at this time, the temperature in the fixed frame 13 often has not reached the preset temperature threshold), the cooling device 8 is started, and the temperature in the fixed frame 13 can be adjusted as soon as possible to keep it relatively stable, thereby reducing the impact of the ambient temperature on the temperature in the fixed frame 13 caused by the opening of the entrance and exit 4, realizing more intelligent temperature control, and improving the storage environment and service life of the stored items in the fixed frame 13.

[0090] Example 3: Fig. 9 , Fig.10As shown, one end of the three-way air valve 10 near the connecting pipe 11 is set as a closed end, and connecting holes are symmetrically arranged on the upper and lower sides of one end of the three-way air valve 10 near the connecting pipe 11. A sealing plate 23 is slidably arranged in the connecting hole. The sealing plate 23 is an arc-shaped structure, and a cavity is arranged on the inner side of the sealing plate 23. A rotating shaft 24 is rotatably arranged at the center of the inner wall of the closed end. A torsion spring is sleeved on the rotating shaft 24, one end of the torsion spring is connected to the rotating shaft 24, and the other end of the torsion spring is connected to the inner wall of the closed end. A gear 25 is arranged on the rotating shaft 24, and racks 26 are vertically arranged on the front and rear sides of the gear 25. The rack 26 meshes with the gear 25, and one side of the rack 26 is slidably connected to the inner wall of the closed end up and down. The two racks 26 are symmetrically distributed about the center of the gear 25, and one end of the rack 26 is connected to the inner wall of the sealing plate 23. A connecting component is arranged between the connecting pipe 11 and the three-way air valve 10, and the connecting component includes An annular stopper 27 is provided, the outer wall of the annular stopper 27 is connected to the inner wall of the connecting pipe 11, the inner wall of the annular stopper 27 is adapted to the outer wall of the three-way air valve 10, a sealing cylinder 28 corresponding to the sealing plate 23 is arranged at one end of the annular stopper 27 away from the three-way air valve 10, a piston plate 29 is slidably arranged in the sealing cylinder 28, a piston rod 30 is arranged on the side of the piston plate 29 close to the sealing plate 23, one end of the piston rod 30 extends to the outside of the sealing cylinder 28 and is provided with a contact plate 31, a spring 32 is sleeved on the outside of the piston rod 30, an annular groove is provided on the inner wall of the annular stopper 27, an elastic sealing ring 33 is provided in the annular groove, an air cavity is provided in the elastic sealing ring 33, the air cavity is connected with the end of the sealing cylinder 28 away from the contact plate 31 through an air pipe 34, the air pipe 34 is arranged in the annular stopper 27, and a sealing groove 35 adapted to the elastic sealing ring 33 is provided on the outer wall of the three-way air valve 10.

[0091] When the three-way air valve 10 is connected to the connecting pipe 11, first align the connecting pipe 11 with the closed end of the three-way air valve 10 and insert it. The air outlet end of the three-way air valve 10 is tapered, and the inner wall of the annular stopper 27 is adapted to the air outlet end of the three-way air valve 10. When the connecting pipe 11 can no longer move, the three-way air valve 10 and the connecting pipe 11 are initially connected. Under the sealing effect of the annular stopper 27, the leakage of the low-temperature gas can be reduced. Then, the low-temperature gas is transmitted to the connecting pipe 11 through the three-way air valve 10. Under the pressure of the low-temperature gas, the two sealing plates 23 slide synchronously toward the outside of the three-way air valve 10, and the low-temperature gas can enter the connecting pipe 11. The low-temperature gas flows out from the side wall of the three-way air valve 10, which can reduce the instantaneous impact of the low-temperature gas on the axial direction of the connecting pipe 11 and improve The reliability of the connection between the connecting pipe 11 and the three-way air valve 10 is improved. As the sealing plate 23 slides outward, the sealing plate 23 pushes the contact plate 31 to move toward the inner wall of the connecting pipe 11. The contact plate 31 drives the piston plate 29 to slide in the sealing cylinder 28 through the piston rod 30, so that the gas in the sealing cylinder 28 flows into the air cavity of the elastic sealing ring 33 through the air pipe 34. The elastic sealing ring 33 expands and fills the sealing groove 35, further improving the sealing performance of the connection between the connecting pipe 11 and the three-way air valve 10, reducing the leakage of low-temperature gas, and facilitating the precise control of the temperature inside the fixed frame 13. The greater the low-temperature gas pressure at the outlet end of the three-way air valve 10, the greater the expansion degree of the elastic sealing ring 33, and the better the sealing performance of the connecting pipe 11 and the three-way air valve 10.

[0092] Working principle: When using the storage management cabinet to store items, the first baffle 6 rotates to expose the entrance and exit 4, and the mechanical gripper arm 19 grabs the items at the entrance and exit 4. During the grabbing process, the intelligent storage system binds the new item to the RFID tag, establishes a mapping relationship between the RFID tag and the item data, records the number of times it is taken out, the storage time, and the time difference between two adjacent deposits, and calculates with the calculation of the position distribution calculation module, and concludes that the item needs to be placed in one of the first area 20, the second area 21 and the third area 22, and the placement area corresponds to the roller at the lower end of the storage rack 17. The wheel 15 rotates and drives the storage rack 17 to be exposed laterally, and the mechanical clamping arm 19 places the items inside the storage rack 17. The rotation of the roller 15 then stores the items and the storage rack 17 into the fixed frame 13, and the cooling device 8 is started. The cooling device 8 transmits the required low-temperature gas to the fixed frame 13 through the pipeline 9. The gas flows into the connecting groove 14 through the connecting pipe 11 and completely fills the storage rack 17. When taking out the items, the storage rack 17 is pushed out by the rotation of the roller 15, so that the mechanical clamping arm 19 can complete the grabbing of the items, and finally the items can be sent to the entrance and exit 4 position.
