Description

Technical Field

[0001] This utility model relates to the technical field of warehousing and transportation systems, and in particular to a four-way shuttle system with QR code positioning. Background Technology

[0002] The four-way shuttle system is a widely used logistics system in automated warehouses (AS / RS). It mainly consists of guide rails, four-way shuttles, and positioning devices. The guide rails form the primary frame structure, allowing the four-way shuttles to move in multiple directions along them and achieve their designated positions during movement using the positioning devices. Accurate positioning of the four-way shuttles is crucial for improving inventory management efficiency and reducing operational errors in AS / RS management.

[0003] Existing positioning methods for four-way shuttles typically involve using QR code labels and industrial cameras. This involves attaching QR codes to the upper surface of the track and mounting industrial cameras on the four-way shuttle. When the shuttle passes the corresponding location, the industrial camera scans the QR code to obtain positioning information.

[0004] In the above solution, on the one hand, since the four-way shuttle needs to move in multiple directions, the camera shooting angle needs to be adjusted for the QR codes pasted in different positions, which can easily lead to shooting errors. On the other hand, the surface of the QR code pasted on the upper end of the track is prone to dust accumulation or wear by the four-way shuttle, which can easily lead to unclear shooting and affect positioning accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a four-way shuttle system with QR code positioning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A four-way shuttle system with QR code positioning includes a guide rail frame, a four-way shuttle, and several QR code components.

[0008] The guide rail frame has a track surface and a non-track surface;

[0009] The four-way shuttle includes a main body, a drive unit and a QR code camera mounted on the main body. The drive unit can drive the main body to translate on the track surface, and the QR code camera can scan the scanning surfaces of different QR code components during the translation process.

[0010] Several of the QR code components are arranged along the translational direction of the four-way shuttle and are installed on the non-track surface;

[0011] The scanning surface of the QR code component forms a preset angle A with the vertical plane, and the value of A is within the range of 0°≤A≤45°.

[0012] Preferably, the guide rail frame includes a plurality of first guide rail frames and a plurality of second guide rail frames;

[0013] The first guide rail frame and the second guide rail frame are connected perpendicularly to each other to form several empty areas;

[0014] Each of the empty areas is provided with at least two QR code components, one of which is disposed on the first guide rail and the other of which is disposed on the second guide rail;

[0015] The QR code camera includes a first QR code camera and a second QR code camera, with the first QR code camera and the second QR code camera respectively facing the two QR code components.

[0016] Preferably, the QR code component includes a mounting plate and a QR code label;

[0017] The QR code label is affixed to the side of the mounting plate facing the QR code camera.

[0018] Preferably, a plurality of QR code labels are provided along the translational direction of the four-way shuttle.

[0019] Preferably, the QR code on the QR code label includes coordinate information.

[0020] Preferably, the QR code camera is located at the bottom of the main body.

[0021] Preferably, the driving unit is provided in several groups to drive the main body to translate in different directions;

[0022] Each drive unit includes several wheels, with at least two wheels symmetrically arranged about the QR code camera.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model provides a four-way shuttle system with QR code positioning. By installing the QR code component on the non-track surface of the guide rail frame, the installation of the QR code component can avoid affecting the stable operation of the four-way shuttle. At the same time, it can also prevent the scanning surface of the QR code component from being scratched during the movement of the four-way shuttle, thereby avoiding affecting the accurate positioning of the four-way shuttle.

[0025] Furthermore, setting the scanning surface of the QR code component at a preset angle with the vertical plane serves two purposes. First, it allows the QR code camera to align with the scanning surface of the QR code component, facilitating scanning to obtain the positioning information of the four-way shuttle. Second, it prevents dust accumulation on the scanning surface of the QR code component from affecting clarity, ensuring that the QR code camera can clearly scan the scanning surface of the QR code component.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] See Figures 1 to 4 This utility model provides a four-way shuttle system for QR code positioning, including a guide rail frame 1, a four-way shuttle 2, and several QR code components 3; wherein, the guide rail frame 1 has a track surface 101 and a non-track surface 102; the four-way shuttle 2 includes a main body 21, and a drive unit 22 and a QR code camera 23 mounted on the main body 21. The drive unit 22 can drive the main body 21 to translate on the track surface 101, and the QR code camera 23 can scan the scanning surface 301 of different QR code components 3 during the translation process; several QR code components 3 are arranged along the translation direction of the four-way shuttle 2 and are mounted on the non-track surface 102; the scanning surface 301 of the QR code component 3 forms a preset angle A with the vertical plane, and the preset clamp A can be set to 0°, that is, the scanning surface 301 of the QR code component 3 is parallel to the vertical plane.

[0037] Of course, in other embodiments, A can also be slightly tilted toward the QR code camera 23 to facilitate scanning by the QR code camera 23. For example, A can be set to 5°, 10°, 15°, 30° or 45°, that is, the value range of A can satisfy: 0°≤A≤45°. The specific setting can be made according to the actual situation.

[0038] It is worth noting that the aforementioned “track surface 101” is the plane in contact with the drive unit 22, while the “non-track surface 102” is the side wall and bottom wall of the guide rail 1 (that is, the plane that does not contact the drive unit 22).

[0039] It is easy to understand that, in the above solution, installing the QR code component 3 on the non-track surface 102 of the guide rail frame 1 can avoid the QR code component 3 from affecting the smooth operation of the four-way shuttle 2. At the same time, it can also prevent the scanning surface 301 of the QR code component 3 from being scratched during the movement of the four-way shuttle 2, thereby avoiding affecting the accurate positioning of the four-way shuttle 2.

[0040] Furthermore, setting the scanning surface 301 of the QR code component 3 at a preset angle with the vertical plane serves two purposes. First, it allows the QR code camera 23 to be aligned with the scanning surface 301 of the QR code component 3, thus facilitating scanning by the QR code camera 23 to obtain the positioning information of the four-way shuttle 2. Second, it prevents dust accumulation on the scanning surface 301 of the QR code component 3 from affecting clarity, thereby ensuring that the QR code camera 23 can clearly scan the scanning surface 301 of the QR code component 3.

[0041] See Figures 2 to 4 The guide rail frame 1 includes several first guide rail frames 11 and several second guide rail frames 12; the first guide rail frames 11 and the second guide rail frames 12 are perpendicularly connected to each other to form several empty areas 4; each empty area 4 is provided with at least two QR code components 3, one QR code component 3 is disposed on the first guide rail frame 11 and the other QR code component 3 is disposed on the second guide rail frame 12; the QR code camera 23 includes a first QR code camera 231 and a second QR code camera 232, the first QR code camera 231 and the second QR code camera 232 are respectively facing the two QR code components 3.

[0042] It is easy to understand that the first guide rail frame 11 and the second guide rail frame 12 are set vertically, thus enabling the four-way shuttle 2 to move on a plane. Each of the first and second guide rail frames 11 and 12 is equipped with a QR code component 3. One QR code component 3 can be scanned by the first QR code camera 231, and the other QR code component 3 can be scanned by the second QR code camera 232, thereby enabling the positioning of the four-way shuttle 2 as it moves in different directions. Compared to using a single QR code camera 23 to scan the QR code components 3 in different directions, this method avoids errors caused by adjusting the scanning angle of a single QR code camera 23, and can also use the positioning information from two directions to jointly locate the position information of the four-way shuttle 2, thus increasing positioning accuracy.

[0043] Furthermore, the QR code component 3 includes a mounting plate 31 and a QR code label 32; the QR code label 32 is affixed to the side of the mounting plate 31 facing the QR code camera 23, so as to facilitate cleaning of the mounting plate 31 during maintenance, and also to facilitate the replacement of the QR code label 32.

[0044] Furthermore, along the translational direction of the four-way shuttle 2, several QR code tags 32 are set, which can effectively extend the positioning field of view, increase the detection range of the QR code tags 32, and increase the positioning accuracy.

[0045] Furthermore, the QR code label 32 is formed using a thermal printer to reduce costs.

[0046] In order for the QR code camera 23 to directly obtain positioning information and complete positioning verification by scanning the QR code label 32, in this embodiment, the QR code on the QR code label 32 includes coordinate information.

[0047] See Figure 3 and Figure 4 The QR code camera 23 is located at the bottom of the main body 21 so that the QR code camera 23 can be better aligned with the QR code component 3, increasing the field of view of the QR code camera 23, thereby increasing the stability and accuracy of positioning.

[0048] Furthermore, the drive unit 22 is provided in several groups to drive the main body 21 to translate in different directions; each drive unit 22 includes several wheels, with at least two wheels symmetrically arranged about the QR code camera 23 to ensure the stability of the QR code camera 23 during movement and to avoid the QR code camera 23 shifting as it moves with the main body 21, thus affecting the detection accuracy.

[0049] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
