Description

Technical Field

[0001] The utility model relates to the field of automation technology, in particular to a radio frequency scanning device. Background Art

[0002] In modern warehouse management systems, accurate and timely knowledge of inventory information is an important means to improve warehouse management efficiency and optimize inventory management. Traditional warehouse management mainly relies on manual inventory counting and data entry, which is not only time-consuming and labor-intensive, but also prone to data errors, resulting in discrepancies between accounts and actuals. This method has become inadequate in the face of increasingly complex and large warehouse management needs.

[0003] At present, radio frequency identification (RFID) technology is widely used in warehouse management as an automatic identification technology. RFID technology can identify target objects and obtain relevant data through radio waves. It has the advantages of fast identification speed, long identification distance, and no need for human intervention. The application of RFID technology in warehouse management can realize automatic identification and information collection of items, greatly improving the efficiency and accuracy of warehouse management.

[0004] However, existing RFID technology still has some limitations in practical applications. For example, RFID scanning equipment usually needs to be carried manually or installed on fixed equipment when moving in the warehouse, which has poor flexibility and makes it difficult to achieve a comprehensive scan of all items on the shelves. In addition, existing RFID scanning equipment can usually only cover one side of the shelf and cannot efficiently collect information about items on both sides of the shelf, resulting in incomplete information collection. Furthermore, the power management and data transmission issues of RFID scanning equipment are also a challenge, especially in large-scale applications. How to effectively charge the equipment and ensure real-time data transmission is an urgent problem to be solved. Utility Model Content

[0037] By installing a charging status indicator light and a signal connection status indicator light on the outer shell of the base body, the operator can intuitively understand the charging status and data connection status of the device; this makes the operating status of the device clear at a glance, making it easy to discover and solve problems in a timely manner and improve work efficiency.

[0038] A base processor is provided on the base body, which can receive and process data collected by the radio frequency scanning device, reduce the burden of the processor of the radio frequency scanning device, and improve the data processing speed and efficiency, especially when processing large amounts of data.

[0039] The base processor transmits data to the main control system through the network cable interface or wireless transmission module, providing a variety of data transmission methods. Operators can choose the most suitable transmission method according to actual needs, thereby improving the flexibility and adaptability of data transmission.

[0040] The base is equipped with a processor, which increases the redundancy of the system.

[0043] The addition of the base processor provides more possibilities for system expansion. In the future, the device functions can be expanded through software upgrades or the addition of modules to adapt to more diverse application scenarios and improve the adaptability and scalability of the system.

[0044] As a preferred technical means: the positioning assembly includes a plurality of first guide wheels, which are respectively located around the upper part of the base body, and the radio frequency scanning device is inserted from top to bottom along the guide wheels until the bottom plane of the radio frequency scanning device is against the top plane of the base body.

[0045] The multiple first guide wheels in the positioning assembly are located around the upper part of the base body, ensuring that the radio frequency scanning device can be smoothly and accurately inserted and positioned from top to bottom, ensuring that the device is stably and reliably connected.

[0046] The design of the first guide wheel makes the installation and removal of the radio frequency scanning device easier and quicker. The operator can complete the insertion and removal of the device without complicated adjustments, which greatly simplifies the operation process of the device.

[0047] The setting of the guide wheel effectively prevents the RF scanning device from being misplaced during the insertion process, ensures the stable placement of the device on the base, avoids problems such as charging and data transmission caused by misplacement, and improves the reliability of device operation.

[0048] Precise guiding and positioning components can reduce friction and collision between the RF scanning device and the base during the plug-in and unplug process, reduce equipment wear, extend equipment life, and reduce maintenance and replacement costs.

[0049] Guided by the guide wheels, the RF scanning device can be smoothly inserted into the base and firmly positioned, ensuring the stability of the equipment during operation and avoiding problems such as work interruption and data loss caused by equipment shaking or displacement.

[0050] As a preferred technical means: the second communication component and the first communication component both include Bluetooth components.

[0051] By including Bluetooth components in both the second communication component and the first communication component, wireless data transmission between the radio frequency scanning device and the base is achieved, which does not require physical connection, simplifies the installation and removal process of the device, and improves the mobility of the device.

[0052] Using Bluetooth for data transmission can reduce the complexity and cost of wiring, eliminate the need for additional cable connections, make the working environment tidier, and reduce the risk of failures caused by cable breakage or poor contact.

[0053] Bluetooth technology has the characteristics of low power consumption, which is suitable for devices that need to run for a long time, extending the battery life of RF scanning devices and bases, and reducing the need for frequent charging.

[0054] Wireless connectivity reduces the use of physical interfaces, thereby reducing the possibility of interface wear and damage, and simplifying equipment maintenance and care.

[0055] Bluetooth technology has good anti-interference capabilities and can provide stable data transmission in complex storage environments, ensuring that the data collected by the RF scanning device can be reliably transmitted to the base.

[0056] The use of Bluetooth components allows the RF scanning device to be free from the constraints of cables when moving, allowing operators to operate the equipment more freely, improving work efficiency and flexibility.

[0057] As a preferred technical means: the base body is "concave" in shape, with two upward support seats formed on both sides, the inner sides of the support seats are provided with guide strips parallel to the support seats, and a row of second guide wheels are provided on the top surfaces of the guide strips; the guide strips and the second guide wheels match the bottom of the radio frequency scanning device; a limiting assembly is provided at the rear ends of the two support seats, and the radio frequency scanning device is pushed from front to back along the second guide wheels until the radio frequency scanning device abuts against the limiting assembly.

[0058] The main body of the base is "concave" in shape, with upward support bases formed on both sides, so that the RF scanning device can obtain stable support when inserted into the base, preventing the device from tilting or shaking, and ensuring the stability and reliability of the device on the base.

[0065] The open "concave" structure helps dissipate heat from the equipment, prevents overheating caused by long-term operation of the equipment, and improves the service life and reliability of the equipment.

[0066] As a preferred technical means: the charging connector is a metal conductive sheet arranged on the upper surface of the base body, which is in contact with the conductive piece at the bottom of the radio frequency scanning device to form a power supply channel.

[0067] By setting a metal conductive sheet on the upper surface of the base body and connecting it with the conductive part at the bottom of the RF scanning device, a simple charging channel is formed. The operator only needs to place the RF scanning device on the base to automatically start charging, eliminating the tedious steps of plugging and unplugging the charging cable and simplifying the operation process.

[0068] Since frequent plugging and unplugging operations are eliminated, the contact connection between the metal conductive sheet and the conductive part reduces the risk of mechanical wear and poor contact, reduces the failure rate, and extends the service life of the equipment and the base.

[0069] The stable charging connection reduces charging interruptions and failures caused by poor contact, improves the reliability and stability of device operation, and ensures that the device can be used normally when needed.

[0070] The metal conductive sheet is arranged on the surface of the base body, which does not occupy additional space, making the base design more compact. The design of the metal conductive sheet and the conductive member reduces the exposed electrical contact points, reduces the risk of accidental electric shock, and enhances the safety of the device.

[0071] Beneficial effects:

[0072] Through the multi-antenna configuration design, the RF scanning device can fully collect the RF tag signals of products on the shelves on both sides when moving between shelves, thereby improving the coverage and accuracy of signal collection.

DETAILED DESCRIPTION

[0082] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings of the specification.

[0083] Embodiment 1:

[0084] like Figure 1 A radio frequency scanning device includes a radio frequency scanning device, which includes: a shell 10, a radio frequency antenna 20, a reader / writer, a processor, a power supply component and a first communication component, wherein the processor is communicatively connected to the reader / writer and the first communication component; the radio frequency antenna 20 is implemented as at least two, and the radio frequency antenna 20 is arranged on both sides of the overall structure of the scanning device.

[0085] Figure 1 The housing 10 and the RF antenna 20 are shown in the figure, which contain a reader / writer, a processor, a power supply component and a first communication component. As a feasible implementation method, the processor uses an externally purchased edge gateway, and the first communication component is an externally purchased Bluetooth component. Specifically, a Bluetooth antenna interface 30 is configured on the housing, one end of the Bluetooth antenna interface 30 is connected to the Bluetooth antenna, and the other end is connected to the Bluetooth chip, and the Bluetooth chip is connected to the processor to realize data reception and transmission control.

[0086] There are two solutions for the power supply component, one of which is to take out the charging mode, and then assemble it back into the product after charging. Since the RF scanning device needs to be frequently used during the warehouse inventory operation, it is not convenient to take out the power supply charging mode, and the disassembly and assembly are cumbersome. Therefore, a base charging mode is proposed, such as Example 2.

[0087] The radio frequency scanning device also includes a reader indicator light 40, and the indication content of the reader indicator light 40 includes indicating the normal and abnormal operation status of the reader. The reader indicator light 40 is fixed to the housing, and the light display is exposed to the human eye. As an optional implementation, the reader indicator light includes two, one is a green light, which flashes to indicate that the reader is operating normally, and the other is a red light, which is a normally closed light and lights up when an abnormality occurs.

[0088] A solution for scanning in opposite directions is proposed. Specifically, two radio frequency antennas 20 are implemented and arranged on both sides of the housing. The transmission directions of the radio frequency antennas 20 are opposite. The specific application is that there are several shelves arranged in a warehouse, and the radio frequency scanning device runs in the middle of the shelf. The radio frequency antennas are respectively facing the directions of the shelves on both sides to scan the goods carrying radio frequency tags on the shelves.

[0089] The operation of the radio frequency scanning device in the middle of the shelf can be implemented by manually grabbing the device for scanning, or by carrying the scanning through equipment such as automated robots.

[0090] The radio frequency scanning device also includes a debugging network port 50, which is installed on the housing and used to connect to an external network cable. The debugging network port 50 is connected to the processor for communication. An external computer is used to perform startup debugging, scanning mode debugging or maintenance of the edge gateway.

[0091] Embodiment 2:

[0092] There are many options for the power supply component, one of which is to remove the charging mode, and then assemble it back into the product after charging. Since the RF scanning device needs to be frequently used during the warehouse inventory operation, it is not convenient to remove the power supply charging mode, and the disassembly and assembly are cumbersome. Therefore, a base charging mode is proposed.

[0093] The same points as in the first embodiment are not described in detail, except that:

[0094] like Figure 2 , 3 As shown in FIG. 4 , a radio frequency scanning device further includes a base, on which the radio frequency scanning device disclosed in the first embodiment can be detachably mounted, and the base includes a base body 60, on which the radio frequency scanning device can be detachably mounted; the base body 60 includes the following structure:

[0095] A charging connector 61, which is electrically connected to the bottom of the radio frequency scanning device;

[0096] The charging external connection component 62 is used for connecting to the mains power supply. An air switch 67 is also electrically connected to the charging external connection component.

[0097] The second communication component is communicatively connected with the first communication component and is used for data transmission. When in use, the data collected by the radio frequency scanning device is transmitted to the base through the Bluetooth component. If the first communication component adopts the Bluetooth component as disclosed in the first embodiment, the second communication component is correspondingly implemented as another group of Bluetooth components. The shell of the base body is equipped with a base Bluetooth antenna interface 63 for installing a Bluetooth antenna.

[0098] The third communication component is connected to the external main control system for communication; this embodiment lists a solution as a network cable interface 64.

[0099] The base processor is connected to the second communication component and the third communication component. The data collected by the radio frequency scanning device is transmitted to the base through the second communication component and the third communication component. In this way, when the radio frequency scanning device is taken out for operation, the staff can still transmit data from the base through the network cable interface 64, which is more flexible in the time when the main control system obtains the collected data. Furthermore, the base can also use wireless data transmission to transmit data to the main control system, and configure a corresponding wireless transmission module.

[0100] The positioning component is in contact with the radio frequency scanning device and is used to stably and accurately mount the radio frequency scanning device on the base, at least realizing the functions of charging and fixing.

[0101] The so-called detachable installation can be understood as that, since the radio frequency scanning device needs to be taken out from the base for use, the radio frequency scanning device is fixed on the base body and can be taken out when used.

[0102] The charging connector 61 is implemented as a metal conductive sheet 65 disposed on the upper surface of the base body.

[0103] The base body 60 is a concave structure, and three metal conductive sheets 65 are installed on the upper surface of the protruding structures on both sides of the base body 60. When the RF scanning device is placed on the upper surface, the bottom of the RF scanning device is electrically connected to the metal conductive sheets. Correspondingly, the bottom of the RF scanning device is provided with a coupling structure that cooperates with the metal conductive sheets 65, and the coupling structure is connected to the power supply component of the RF scanning device.

[0104] The housing of the base body is equipped with a base indicator light 66, which indicates the charging status and signal connection status. In this embodiment, a feasible solution is listed, specifically, the indicator light includes a red light, a green light and a blue light. The green light indicates whether the base is connected to the external system (such as the warehouse system) normally, and is a constant light; the blue light indicates whether the base is connected to the radio frequency scanning device normally; the red light is the power light. Among them, the specific content of the indication is different and is adjusted according to the actual situation.

[0105] like Figure 4 The positioning assembly includes a first guide wheel 70 installed around the upper part of the base body, and the overall layout of all the first guide wheels 70 is adapted to the radio frequency scanning device. One of the factors for fixing the radio frequency scanning device by using the first guide wheel as a positioning mechanism is that the first guide wheel can slide to allow the radio frequency scanning device to be smoothly installed downward.

[0106] Embodiment three:

[0107] The same points as the second embodiment are not described in detail, but the difference is that:

[0108] This embodiment provides another positioning component of a radio frequency scanning device, such as Figure 5 The positioning assembly includes two sets of guide bars 80 arranged in parallel, the two sets of guide bars 80 are arranged on both sides of the upper part of the base body, and a row of second guide wheels 81 are arranged on the guide bars; the guide bars and the guide wheels are installed in cooperation with the bottom of the radio frequency scanning device; and the extension end positions of the two guide bars are both provided with limit assemblies 90.

[0109] When in use, the radio frequency scanning device is pushed from one end toward the limiting assembly, and the positioning installation is achieved when it is pushed to contact the limiting assembly 90. A sliding groove is provided at the bottom of the radio frequency scanning device to cooperate with the guide bar and the guide wheel.

[0110] The radio frequency scanning device shown above is a specific embodiment of the present utility model, which has embodied the substantial characteristics and progress of the present utility model. According to actual use needs and under the guidance of the present utility model, equivalent modifications in shape, structure, etc. can be made to the device, which are all within the protection scope of this scheme.
