Description

Technical Field

[0001] The utility model relates to the technical field of automated logistics warehousing systems, in particular to a pallet position detection device. Background Art

[0002] In modern logistics and warehousing systems, pallets are a commonly used tool for handling goods, and their accurate placement in designated locations is crucial to improving work efficiency.

[0003] In the existing technology, the positioning of the pallet usually relies on technologies such as mechanical limit or photoelectric sensor, but these technologies have certain limitations. For example, the mechanical limit is easily affected by wear and tear, and the photoelectric sensor may make misjudgments due to changes in ambient light. Therefore, there is an urgent need for a stable and reliable pallet positioning detection device. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides a pallet position detection device, which aims to detect whether the pallet is correctly inserted into the mother slot position by means of a magnetic sensor, so as to achieve fast, accurate and stable pallet positioning.

[0005] The above invention objectives of the present application are achieved through the following technical solutions:

[0006] A magnetic element, which is disposed on the tray and is used to emit a magnetic field;

[0007] A magnetic sensor, which is disposed on the external positioning mechanism and is used to sense a magnetic field and continuously emit a sensing signal;

[0008] A sensing system, the sensing system is used to receive the sensing signal of the magnetic sensor;

[0009] A control system, the control system being control-connected to the sensing system;

[0010] The sensing system compares the sensing signal with a preset threshold value and feeds back the comparison result to the control system to determine whether the tray is correctly installed.

[0011] By adopting the above technical solution, when the pallet is stored and installed close to the external positioning mechanism, the magnetic sensor located in the external positioning mechanism can sense the magnetic field emitted by the magnetic element in real time, and continuously send the induction signal to the induction system. When the pallet is correctly installed in the specified position, the induction system will send the induction signal reaching the preset threshold to the control system. The control system can prompt the staff for the correct installation, otherwise it will remind the staff to adjust the position of the pallet. Compared with traditional mechanical limit or photoelectric sensor technologies, the induction coordination between the magnetic element and the magnetic sensor can provide a stable and reliable pallet position detection function, which is not easily affected by mechanical wear or changes in ambient light, and has a simple and practical structure.

[0012] In a preferred example, the present application may be further configured as follows: the sensing system includes a signal processor, and the magnetic sensor inputs the generated sensing signal into the signal processor.

[0013] By adopting the above technical solution, the signal processor can filter, amplify, digitize, extract features and other operations on the sensing signal sent by the magnetic sensor, and feed the results back to the control system.

[0014] In a preferred example, the present application can be further configured as follows: the pallet position detection device also includes a mounting member and a card holder, the mounting member is arranged on one side of the pallet, the magnetic element is installed at the bottom of the mounting member, the card holder is arranged on the external positioning mechanism, and the magnetic sensor is arranged on the top of the card holder.

[0015] By adopting the above technical solution, setting the mounting parts and the holder, it is possible to adapt to the installation conditions of various trays and external positioning mechanisms, and at the same time provide installation positions for magnetic elements and magnetic sensors.

[0016] In a preferred example, the present application can be further configured as follows: the mounting member is detachably fixedly connected to the tray by means of a threaded connection, and the holder is detachably fixedly connected to the external positioning mechanism by means of a threaded connection.

[0017] By adopting the above technical solution and using a threaded connection method, it is convenient for workers to install the detection device on trays of different specifications and different external positioning mechanisms.

[0018] In a preferred example, the present application can be further configured as follows: a female groove is provided at the bottom of the mounting member, the magnetic element is installed inside the female groove, a male groove is provided on the socket, the magnetic sensor is arranged inside the male groove, and the specifications of the male groove and the female groove are matched.

[0019] By adopting the above technical solution and setting up male and female groove structures with matching specifications, it is possible to facilitate technicians to install the tray, and provide space between the magnetic element and the magnetic sensor to avoid accidental touch, thereby improving the safety of tray installation.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. When the pallet is stored and installed close to the external positioning mechanism, the magnetic sensor located in the external positioning mechanism can sense the magnetic field emitted by the magnetic element in real time, and continuously send the induction signal to the induction system. When the pallet is correctly installed in the specified position, the induction system will send the induction signal reaching the preset threshold to the control system. The control system can prompt the staff to install it correctly, otherwise it will remind the staff to adjust the position of the pallet. Compared with traditional mechanical limit or photoelectric sensor technologies, the induction coordination between the magnetic element and the magnetic sensor can provide a stable and reliable pallet position detection function, which is not easily affected by mechanical wear or changes in ambient light, and has a simple and practical structure.

[0022] 2. The signal processor can filter, amplify, digitize, extract features, and perform other operations on the sensing signals sent by the magnetic sensor, and feed the results back to the control system.

[0023] 3. By setting up male and female groove structures with matching specifications, it is convenient for technicians to install the tray, and provide space between the magnetic element and the magnetic sensor to avoid accidental touch and improve the safety of tray installation.

[0032] It should be noted that, in the present embodiment, the magnetic element 1 is made of magnetic material so that the magnetic element 1 and the magnetic sensor 2 can realize the induction and detection process through the action of the magnetic field.
