Description

Technical Field

[0001] This utility model relates to the field of medical storage equipment, specifically a cold storage for automatic reagent storage and retrieval. Background Technology

[0002] Currently, reagent storage and retrieval in hospital cold storage facilities primarily rely on manual operation, resulting in low efficiency and inefficient management. Staff must spend extended periods searching for reagents in low-temperature environments, which is not only time-consuming and labor-intensive but also prone to errors due to the cold conditions, increasing their workload. Furthermore, frequent opening and closing of the cold storage doors causes temperature fluctuations, affecting the storage stability of reagents, especially temperature-sensitive biochemical reagents and vaccines, which may become ineffective due to temperature changes, leading to unnecessary waste. Manual management also relies on paper records or simple electronic ledgers, which are prone to omissions or delays in information updates, further exacerbating the chaos in reagent management. Manual operation also faces numerous challenges in reagent identification and storage. Due to the wide variety of reagents and similar packaging, staff easily confuse reagent names, specifications, or expiration dates, leading to misplacement or incorrect retrieval. This not only increases the time cost of subsequent searching and reorganization but may also affect test results due to the misuse of expired or incorrect reagents, even posing medical safety hazards. Therefore, there is an urgent need for a cold storage facility for automated reagent storage and retrieval to improve reagent access efficiency and storage safety. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cold storage for automatic reagent storage and retrieval, comprising an insulated wall, a shelf fixedly installed within the insulated wall, multiple lifting components fixedly connected to the shelf, the multiple lifting components being arranged on the left and right sides, and two conveying components fixedly installed within the insulated wall, the conveying components including a left conveying line and a right conveying line, both the left and right conveying lines being able to convey boxes with filling / empty boxes, the right conveying line being used for conveying empty boxes, the conveying components being located at the bottom of the shelf, and an RFID detection compartment fixedly connected to the conveying components located at the front side of the shelf, the shelf being fixedly connected to two left and right translational components, a robotic arm module being provided at the center of the front side of the shelf, multiple cold storage boxes being positioned and stored on the shelf, and a stacking mechanism being fixedly connected to the center of the shelf. The machine has a shelf fixedly connected to a 3D camera aligned vertically with the external container during output. The 3D camera simultaneously acquires multiple reagent images and their three-dimensional positions. When the external container containing reagents is moved to the RFID detection chamber by the conveying component, the RFID detection chamber automatically detects the reagents inside. The external control screen displays the reagent type and quantity. After the delivery personnel confirm, the container is released. The lifting component moves the external container to the height of the translation component. The stacker crane moves the external container onto the translation component, which then moves it to the left side of the robotic arm module. The 3D camera determines multiple reagent images and their three-dimensional positions, and the robotic arm module uses the vacuum nozzle to classify the reagents in the external container. The stacker crane consists of two upper and lower stacking limit slide rails fixedly connected to the rack.

The stacker crane is equipped with stacker forks, which are fixedly connected to a fourth motor and a fifth motor. The stacker forks contain fork plates. The stacker crane is located between two rows of racks and can move linearly in three directions. The stacker forks can move left and right, and the fourth motor drives a gear meshing with the second rack, causing the stacker forks to move up and down. The fifth motor drives multiple sets of gears and racks, causing the fork plates to move left and right, achieving three-way movement of the fork plates. This allows the stacker crane to lift external material boxes or storage boxes and move them to any storage location on the racks.

[0005] Preferably, the lifting assembly includes a mounting frame fixedly connected to the shelf, a lead screw module fixedly connected to the mounting frame, a second motor fixedly connected to the lower end face of the lead screw module, an adapter plate fixedly fixed to the lead screw module, a lifting fork fixedly connected to the adapter plate, and multiple limiting plates fixedly connected to the lifting fork. The lifting assembly uses a lead screw structure for lifting, and with the limiting plates around the fork, the position is relatively fixed. Thus, the second motor drives the lead screw module to rotate, thereby moving the lifting fork up and down, realizing the raising and lowering of the external material box and the warehouse storage box. Preferably, the translation component comprises two sets, located at the front end of the shelves on both sides. The translation component includes a mounting plate fixedly connected to the shelf, and two guide rails slidably connected to the mounting plate. A material box placement rack is fixedly connected to the guide rails. The material box placement rack includes two material box positions on each side. The material box holds the external material box and the storage box in the warehouse. The material box positions limit the movement of the external material box and the storage box around its perimeter. The storage box in the warehouse is provided with multiple partition slots for storing different reagents. The shelf is fixedly connected to four first racks located on the lower side of the material box placement rack, and the material box placement rack is fixedly connected to a first motor. The first motor is powered by a first gear. The first gear meshes with the first racks, thereby driving the first gear to rotate and moving the material box placement rack along the first racks to move the external material box and the storage box in the warehouse to the side of the mobile robot for sorting. Preferably, the robotic arm module includes a mounting base fixedly connected to the shelf and a vacuum generating assembly. A mobile robotic arm is fixedly connected to the upper surface of the mounting base. The mobile robotic arm is poweredly connected to a nozzle module, which is poweredly connected to multiple vacuum nozzles. The nozzle module can switch the number of nozzles and the spacing between the nozzles on both sides according to the size of the reagent to stably aspirate reagents of different sizes. The mobile robotic arm uses a six-axis robotic arm to drive the nozzle module, which can be adjusted to six degrees of freedom at the end. Preferably, the insulated wall is provided with two automatic storage doors on the left and right. The automatic storage doors are connected to the conveying assembly at the front and rear. The automatic storage doors can be automatically raised and lowered. When raised, the material box is conveyed through the automatic storage door. After passing through, the storage door is closed. Preferably, a cooling fan is fixedly installed on the top of the insulated wall, and the cooling fan cools the interior of the insulated wall. Preferably, the insulated wall is rotatably connected to two maintenance access doors, one at the front and one at the back, to facilitate staff access. Preferably, the shelf is used for storing material boxes. Each external material box and warehouse storage box has an individual storage location. Each storage location consists of two storage panels fixedly connected to the shelf, located inside the cold storage room. Warehouse storage boxes are placed on the shelf, with partitions set according to the size of individual reagents to restrict the placement of reagents.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates an RFID detection chamber, a lifting component, and a translation component. An external reagent bin, driven by a conveyor component, is moved to the RFID detection chamber for testing. An external control unit records and verifies the type and quantity of reagents. The lifting component moves the external reagent bin upwards, and then a stacker crane moves it directly below a 3D camera. The 3D camera captures the size and placement of the reagent kits, simultaneously acquiring multiple reagent images and their three-dimensional positions. A robotic arm module, in conjunction with a suction nozzle module, places the reagents from the external bin into storage boxes for separate storage. This allows for automatic reagent sorting and warehousing based on online orders, saving manpower and avoiding temperature fluctuations caused by frequent personnel movement. It also accurately tracks reagent quantities and expiration dates, facilitating reagent management.

[0007] This utility model incorporates a stacking limit slide rail, a fork plate, and stacker crane forks. The stacker crane consists of upper and lower stacking limit slide rails. A third motor drives two second synchronous pulleys to rotate via a first synchronous pulley, causing the stacker crane forks to move along the second synchronous belt. A fourth motor drives gears, which in turn drive racks to move the stacker crane forks up and down along the second rack. A fifth motor drives multiple sets of gears and racks to move the fork plate left and right, achieving three-way movement of the fork plate. This allows the stacker crane to support external bins and warehouse storage boxes, enabling them to be moved to any storage location on the rack for convenient storage and retrieval.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Example 1:

[0011] Please see Figure 1-8This utility model provides a technical solution: a cold storage for automatic reagent storage and retrieval, comprising an insulated wall 100, a shelf 104 fixedly installed inside the insulated wall 100, and multiple lifting components 111 fixedly connected to the shelf 104. The lifting components 111 are arranged on the left and right sides, and two conveying components 108 are fixedly installed inside the insulated wall 100. The conveying components 108 include a left conveying line and a right conveying line. Both the left and right conveying lines can be used to convey boxes with fillings / empty boxes, and the right conveying line is used to convey empty boxes. The conveying components 108 are located at the bottom of the shelf 104, and an RFID detection compartment 109 located at the front of the shelf 104 is fixedly connected to the conveying components 108. The shelf 104 is fixedly connected to two left and right translation components 107. A robotic arm module 106 is provided at the center of the front side of the shelf 104. Multiple storage boxes 113 are positioned and stored on the shelf 104, and a stacker crane 105 is fixedly connected to the center of the shelf 104. The shelf 104 is fixedly connected to a 3D camera 145, which is vertically aligned with the external material box 112 during output. The 3D camera 145 simultaneously acquires multiple reagent images and three-dimensional positions. When the external material box 112 containing reagents is moved to the RFID detection chamber 109 by the conveying component 108, the RFID detection chamber 109 automatically detects the reagents in the box. The external control screen displays the reagent type and quantity. After the delivery personnel confirm, the box is released. The lifting component 111 moves the external material box 112 to the height of the translation component 107. The stacker crane 105 moves the external material box 112 onto the translation component 107. The translation component 107 then moves the external material box 112 to the left side of the robotic arm module 106. The 3D camera 145 determines multiple reagent images and three-dimensional positions. The robotic arm module 106 uses the vacuum nozzle 131 to classify the reagents in the external material box 112. The lifting assembly 111 includes a mounting frame 120 fixedly connected to the shelf 104. A lead screw module 121 is fixedly connected to the mounting frame 120. A second motor 122 is fixedly connected to the lower end face of the lead screw module 121. An adapter plate 124 is fixedly fixed on the lead screw module. A lifting fork 125 is fixedly connected to the adapter plate 124. A plurality of limiting plates 126 are fixedly connected to the lifting fork 125. The lifting assembly 111 uses a lead screw structure for lifting. With the help of the limiting plates 126 around the lifting fork 125, the position is relatively fixed. Thus, the second motor 122 drives the lead screw module 121 to rotate, thereby moving the lifting fork 125 up and down, realizing the raising and lowering of the external material box 112. The translation component 107 comprises two sets, located at the front ends of the side shelves respectively. Each translation component 107 includes a mounting plate 115 fixedly connected to the shelf 104. Two guide rails 119 are slidably connected to the mounting plate 115. A material box placement rack 114 is fixedly connected to each guide rail 119. The material box placement rack 114 includes two material box positions on each side. An external material box 112 and a storage box 113 are engaged within each material box. The material box positions limit the movement of the external material box 112 and the storage box 113 around their perimeter. The storage box 113 is provided with multiple dividing slots for differentiated storage. For different reagents, the shelf 104 is fixedly connected to four first racks 116 located under the material box placement rack 114, and the material box placement rack 114 is fixedly connected to a first motor 117. The first motor 117 is powered by a first gear 118, which meshes with the first racks 116. Thus, the first motor 117 drives the first gear 118 to rotate, which in turn drives the material box placement rack 114 to move along the first racks 116, moving the external material box 112 and the warehouse storage box 113 to the side of the mobile robot arm 129 for sorting. The robotic arm module 106 includes a mounting base 127 and a vacuum generating assembly 128 fixedly connected to the shelf 104. A mobile robotic arm 129 is fixedly connected to the upper surface of the mounting base 127. The mobile robotic arm 129 is poweredly connected to a nozzle module 130. The nozzle module 130 is poweredly connected to multiple vacuum nozzles 131. The nozzle module can switch the number of nozzles and the spacing between the nozzles on both sides according to the size of the reagent to stably pick up reagents of different sizes. The mobile robotic arm 129 uses a six-axis robotic arm to drive the nozzle module, which can be adjusted to six degrees of freedom at the end.

[0012] Example 2:

[0013] Please see Figure 1-8 In order to facilitate the movement of the external material box 112 and the warehouse storage box 113 for sorting and storing reagents, a stacker crane fork 110, a fork plate 143 and a coupling 135 are provided. The stacker crane 105 consists of two upper and lower stacking limiting slide rails 132 fixedly connected to the rack 104. Each stacking limiting slide rail 132 is fixedly connected to two left and right second synchronous belts 144. Each stacking limiting slide rail 132 is slidably connected to a sliding connecting plate 133. A column 138 is fixedly connected between the sliding connecting plates 133. A second rack 139 is fixedly connected to the column 138. A third motor 136 is fixedly connected to the lower sliding connecting plate 133. The third motor 136 is powered by a first synchronous pulley 137. The rotation of the first synchronous pulley 137 can drive the coupling 135 to rotate. The coupling 135 is fixedly connected to two upper and lower second synchronous pulleys 134 that mesh with the second synchronous belts 144. The column 138 is fixedly connected to the rack 104. 8. A stacker crane fork 110 is slidably connected vertically. The stacker crane fork 110 is fixedly connected to a fourth motor 140 and a fifth motor 142. The stacker crane fork 110 is provided with a fork plate 143. The stacker crane 105 is located between two rows of shelves and can perform linear movement in three directions. The stacker crane fork 110 can move in both left and right directions. Thus, the fourth motor 140 drives the gear meshing with the second rack 139, which drives the stacker crane fork 110 to move vertically. In conjunction with the fifth motor 142 driving multiple sets of gears and racks, the fork plate 143 moves left and right, realizing the three-way movement of the fork plate 143. This allows the stacker crane fork 110 to lift the external material box 112 or the warehouse storage box 113 and move it to any storage position on the shelf 104. The insulation wall 100 is provided with two automatic storage doors 101 on the left and right. The automatic storage doors 101 are connected to the conveying assembly 108 at the front and rear. The automatic storage doors 101 can be automatically raised and lowered. When raised, the material box is conveyed through the automatic storage door. After passing through, the storage door is closed. A cooling fan 103 is fixedly installed on the top of the insulated wall 100, and the cooling fan 103 cools the interior of the insulated wall 100. The insulated wall 100 is rotatably connected to two maintenance access doors 102 at the front and rear, facilitating staff access. The shelf 104 is used for storing material boxes. Each external material box 112 and the cold storage storage box 113 has an individual storage position. Each storage position consists of two storage plates 146 fixedly connected to the shelf 104 and located inside the cold storage. The cold storage boxes are placed on the shelf, and the shelves are divided according to the size of individual reagents to restrict the position of the reagents.

[0014] Working principle: When receiving an inbound order, the reagents are neatly placed in the external container 112, and the external container 112 is positioned on the left side of the conveying assembly 108 located outside the insulation wall 100. The external control terminal controls the left conveying assembly 108 to move the external container 112 into the RFID detection chamber 109. The RFID detection chamber 109 automatically detects the reagents in the container, and the control terminal screen displays the type and quantity of the reagents. After the delivery personnel confirm, the container is released.

[0015] After the control terminal sends a sorting signal, the external material box 112 is moved to the lifting assembly 111 via the RFID detection bin 109. The second motor 122 is then activated, driving the lead screw module 121 to lift the adapter plate 12 and lifting forks 125, raising the external material box 112 to the height of the translation assembly 107. This, in conjunction with the third motor 136, drives the first synchronous pulley 137 to rotate. The first synchronous pulley 137 drives the coupling 135 to rotate, and the rotation of the lifting forks 125 drives the second synchronous pulley 134 to rotate, causing the stacker crane forks 110 to move back and forth. Furthermore, the fourth motor 140 drives the gear meshing with the second rack 139 to rotate, causing the stacker crane forks 110 to move up and down. In conjunction with the fifth motor 142, a gear set and rack drive the fork plate 143 to move left and right, moving the external material box 112 from the lifting assembly 111 to the translation assembly 107. It can also pick up and deliver the required warehouse storage box 113 from the storage position of the shelf 104 to the translation assembly 107 behind the external material box 112. The size and placement position of the reagent kit are obtained by the 3D camera 145. Preferably, the 3D camera can simultaneously acquire multiple reagent images and three-dimensional positions.

[0016] The mobile robotic arm 129 moves the available vacuum nozzle 131 according to the image and three-dimensional position of the reagent. The mobile robotic arm 129 drives the vacuum nozzle 131 of the nozzle module 130 to the reagent location. The nozzle module 130, in conjunction with the vacuum generating component 128, vacuum adsorbs the reagent through the vacuum nozzle 131 and moves it to the partitioned slot of the storage box 113, realizing partitioned storage. The storage box 113 containing the reagent is moved to the corresponding position on the shelf 104 by the stacker crane 105 for storage. The empty external material box 112 is moved to the right side of the shelf 104 by the stacker crane 105 for standby, or removed for use by the conveyor component 108 on the right side. This realizes automatic sorting and automatic entry and exit of reagents according to the online system orders, saving manpower and avoiding temperature fluctuations caused by frequent personnel entering and exiting. It can accurately count the quantity and expiration of reagents, which is convenient for reagent management.

[0017] The outbound process involves receiving orders, placing the corresponding storage boxes and empty boxes in the warehouse onto the translation component, then having a robotic arm retrieve the corresponding reagents from the storage boxes in the warehouse and place them into an external material box. After the required reagents are sorted, the external material box is sent out through the automatic warehouse door, and the storage boxes in the warehouse return to their corresponding storage locations on the warehouse rack.
