Warehousing is mostly a high-capacity storage mode with multi-layer shelves in flat warehouses. With the standardized management of the industry and the convenience of automated storage and retrieval of goods, it is also necessary to inventory the specifications and quantity of the goods in the cargo locations. At present, inventory is generally carried out manually, which is very time-consuming and inefficient; inventory of high-rise cargo locations requires the use of aerial platforms, which is unsafe and manual inventory is prone to errors. Utility Model Content

[0003] The purpose of the utility model is to solve the deficiencies of the prior art and to provide a multi-layer shelf storage visual inventory device which has a simple structure and can efficiently, accurately and safely realize warehouse inventory, and is particularly suitable for inventory on high-rise shelves.

[0004] The technical solution adopted by the utility model is as follows:

[0015] The switching power supply is to supply stable 24V power to the vision disc library mechanism. The voltage of the battery is 48V. The switching power supply converts the 48V voltage into 24V voltage that can be used by the controller, network module, etc. At the same time, because the voltage of the 48V battery will decay as the power decreases, the switching power supply also plays a role in stabilizing the 24V output voltage when the input voltage changes.

[0016] The beneficial effects of the present utility model:

[0017] 1. The present utility model uses a lifting forklift, such as a fork-type AGV or a manual forklift, to fork and lift the vision disc library mechanism to the height of the goods location to be inventoried and drive and inventory in the shelf aisle. The lifting forklift is convenient to obtain; the distance between the vision disc library mechanism and the goods location shelf is measured by a laser distance measuring pen, and the auxiliary QR code recognition device automatically adjusts the appropriate focal length to scan the QR code information on the shelf to obtain the goods location information. At the same time, the depth and visible light camera sends the goods depth point cloud information and the goods RGB visible light picture information to the controller for processing. The inventory data combination of one goods location is completed through data such as the goods location information, the goods specification, and the goods quantity, and the processed information is uploaded in real time through the wireless client to realize the rapid inventory of the goods in the warehouse; the structure of the present utility model is simple, the operation is convenient, the work efficiency is high, the inventory is safe, and the data is accurate and reliable.

[0018] 2. While the laser distance measuring pen measures the distance between the vision disc library mechanism and the goods location shelf, the visible laser point provides a clear relative height reference between the present utility model and the goods location for the forklift driver, which can help the manual ordinary forklift to position.

[0022] Figure 4 It is the top view after Figure 1 the protective cover is opened;

[0023] Figure 5 It is a control schematic diagram of the vision disc library mechanism. Specific implementation manners

[0024] As Figure 1~Figure 3 shown, a multi-layer shelf storage vision disc library device includes a lifting forklift 1 and a vision disc library mechanism 2 provided on the lifting forklift; the lifting forklift, as a handling device and a lifting device, is used to carry the vision disc library mechanism 2, which is not limited to an ordinary manual forklift and an automatic AGV forklift. It can also lift the vision disc library mechanism to the height of the shelf layer to be inventoried by modifying the forklift to be able to lift and travel in the aisle, and details are not elaborated here.

[0025] Referring to Figure 5 , the vision disc library mechanism includes a base 201 for carrying and installing components. The contact surface between the base and the forklift can adopt a channel-shaped design to facilitate the forklift to pick up the base. A bracket 202 installed on the base for installing a two-dimensional code scanning device 203 and a ranging laser pen 204, and a two-dimensional code scanning device 203 installed on the bracket is used to scan the two-dimensional code pasted on the shelf on one side of the inventory to identify the shelf number (a two-dimensional code corresponding to one shelf number is pre-pasted on each shelf layer). The ranging laser pen 204 is used to measure the distance between the vision disc library mechanism and the shelf and send it to the two-dimensional code scanning device 203 to automatically focus to achieve the best recognition effect. In addition, the laser point emitted by the ranging laser pen can assist the forklift driver to judge whether the current fork height meets the recognition height of the vision disc library mechanism. A depth and visible light camera 206 for identifying the position of the tray carrying the goods on the shelf (each storage location is preset with a tray for placing goods), the depth image of the goods on the shelf, and visible light image information, a battery 210, a power switch, a wireless client 211, and a controller 213 are installed on the base;

[0026] Referring to Figure 3~Figure 4 , the two-dimensional code scanning device, the ranging laser pen, and the depth and visible light camera are respectively electrically connected to the controller. The controller is connected to the wireless client 211, and the other end of the wireless client is connected to the upper system.

[0027] In order to make the inventory more efficient, the base can adopt a rectangular structure, and L-shaped brackets are installed on the diagonals of the base. A QR code scanning device and a ranging laser pen are installed on the L-shaped brackets. The two QR code scanning devices are arranged opposite to each other and face the shelves on both sides of the aisle respectively, so that the goods on the shelves on both sides of the aisle can be counted at the same time.

[0028] Refer to Figure 3~Figure 4 A protective cover 207 is installed on the base, and the battery and power switch, wireless client, and controller are arranged inside the protective cover. An antenna 214 is installed on the side of the protective cover for wireless communication between the warehouse visual disk library device and the upper system.

[0029] A hinge 208 is installed on one side of the protective cover, and a handle 209 is installed on the other side. The protective cover is hinged to the base through the hinge, and the handle 209 is used to lock or open the protective cover.

[0030] It is worth noting that the visual inventory mechanism of the utility model adopts depth and visible light cameras to obtain the combination of depth point cloud data of goods and visible light RGB image data of goods, and classifies and aggregates the appearance styles of goods through visible light RGB images combined with deep learning algorithms. First, deep learning is performed on the appearance styles of various types of goods, and then the visible light RGB images taken during inventory are used for identification, matching and judgment of the specifications of the cargo locations, and the volume of the goods on the pallets in the shelves is calculated in combination with the depth point cloud data. The volume of the missing goods on the cargo location pallet is calculated in combination with the volume of a single cargo and the appearance volume when the pallet is full, thereby counting the number of goods on the cargo location pallet. Among them, the IO signal conversion device, network transmission module, image learning, and training in the controller are existing technologies and will not be repeated here.

[0031] The working principle and working mode of the utility model are as follows:

[0032] When inventory is needed, the upper system sends inventory task information to the automatic AGV, and the automatic AGV drives to the placement point of the visual inventory mechanism to pick up the base. At this time, the battery is automatically connected to power the visual inventory mechanism, and the automatic AGV drives to the starting position of the shelf inventory and automatically rises to the height position of the first layer of the shelf. The automatic AGV starts to drive in the shelf aisle at a certain speed. At this time, the depth camera on the base detects the cargo pallets on both sides of the shelf aisle, that is, the position of the goods on the shelf. The QR code scanning devices on both sides identify the QR code number of the shelf and transmit it to the controller. After the cargo location number is processed by the controller, the processed information is uploaded to the upper system through the wireless client to complete the inventory of the goods. After obtaining all the goods information on the first layer of the shelf in turn, the automatic AGV increases the height to obtain the goods information on the second layer of the shelf and uploads it, completing the inventory of the goods on the entire shelf in turn. The automatic AGV returns to the placement point of the visual inventory mechanism and puts down the visual inventory mechanism. The battery is automatically powered off, and the battery can be charged automatically or manually.

[0033] When a manual ordinary forklift is operated manually, the manual forklift is operated to drive to the placement point of the visual inventory mechanism, the fork-picking mechanism drives to the starting position of the shelf inventory, the key knob switch is turned on to energize the visual inventory mechanism, and the visible infrared light emitted by the infrared laser pen is used to locate the height of the layer of goods that need to be counted. The manually operated forklift starts to drive in the shelf aisle at a certain speed. At this time, the depth camera on the base detects the cargo pallets on both sides of the shelf aisle, that is, the position of the goods on the shelf is located, the QR code scanning device identifies the cargo location information and sends the identified QR code information to the controller, the controller uploads the processed information to the upper system through the wireless client to complete the inventory of goods, and after obtaining the information of all goods on the first shelf in turn, the manual forklift uses the ranging laser pen to locate the height to the second layer of goods and completes the acquisition and upload of the goods information, completing the inventory in the entire warehouse in turn, and the manual forklift returns to the placement point of the visual inventory mechanism, puts down the visual inventory mechanism, turns off the key knob switch, and the battery is powered off. The battery can be charged automatically or manually.
