[0022] It should be noted that the terms "first," "second," etc. (if applicable) in the specification of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of utility models consistent with some aspects of this application.

[0023] Barcode or QR code readers, as key devices for reading barcodes or QR codes, are widely used in product tracking, production control, and automatic identification. Barcode reader mounting brackets in related technologies generally support linear adjustment in three directions: X-axis (left-right), Y-axis (front-back), and Z-axis (up-down). This adjustment method ensures that the reader can move to the optimal reading position both horizontally and vertically.

[0024] However, even with linear adjustment capabilities in these three directions, difficulties in reading or a decrease in recognition rate may still occur in complex and varied real-world application scenarios, such as barcode placement, poor lighting conditions, or limited installation space. This is mainly because the range and flexibility of linear adjustment are insufficient to fully cover all possible installation and reading needs.

[0025] This utility model provides a multi-directional adjustable barcode reader mounting bracket, thereby expanding the adjustment angles of the barcode reader. See also Figure 1 , Figure 1This utility model provides a structural schematic diagram of a multi-directional adjustable barcode reader mounting bracket. The multi-directional adjustable barcode reader mounting bracket includes: a fixed base 1 and an adjustment structure; the fixed base 1 supports the structure of the multi-directional adjustable barcode reader mounting bracket other than the fixed base 1; the adjustment structure includes at least one of a first rotation structure, a second rotation structure, or a third rotation structure 4. The first rotation structure drives the barcode reader to rotate in a first plane, the second rotation structure drives the barcode reader to rotate in a second plane, and the third rotation structure 4 drives the barcode reader to rotate in a third plane. The first plane is a plane perpendicular to the transmission plane of the transmission structure 8 matched with the barcode reader and parallel to the transmission direction of the transmission structure 8; the second plane is a plane parallel to the transmission plane; and the third plane is a plane perpendicular to the transmission plane and perpendicular to the transmission direction.

[0026] Combination Figure 1 The diagram shows a structural schematic of a multi-directional adjustable barcode reader mounting bracket. Figure 2 The diagram shows a disassembled structure of a multi-directional adjustable barcode reader mounting bracket. The fixed base 1 is the foundation of the entire bracket, responsible for supporting and securing all structural components except itself. The fixed base 1 is designed to be robust and durable to ensure the stability and reliability of the entire bracket system. Optionally, the fixed base 1 may be made of various materials and structural forms to adapt to different installation environments and load requirements. For example, it may be made of metal, possessing sufficient strength and rigidity to support the barcode reader and its adjustment structure. The fixed base 1 is mounted on the transmission structure 8.

[0027] The adjustment structure is the core part of the multi-directional adjustable barcode reader mounting bracket, including at least one of the first rotating structure, the second rotating structure, and the third rotating structure 4. These rotating structures together realize the rotational adjustment of the barcode reader on multiple planes.

[0028] The first rotating structure drives the barcode reader to rotate on a first plane. The first plane is defined as a plane perpendicular to the transport plane of the transport structure 8 matched with the barcode reader and parallel to the transport direction. That is, through the first rotating structure, the barcode reader can be tilted along the length of the conveyor belt to accommodate barcode reading needs at different tilt angles. The first rotating structure may employ a rotating shaft, bearing, or other rotating mechanism to achieve smooth rotation of the barcode reader. Furthermore, a locking mechanism may be provided to ensure that the barcode reader remains stable after being adjusted to the desired position. For example, the first rotating unit 6 can rotate along direction A via the first sliding shaft 5.

[0029] The second rotating structure is used to drive the barcode reader to rotate on a second plane. The second plane is defined as a plane parallel to the transmission plane. That is, through the second rotating structure, the barcode reader can be rotated and adjusted in the horizontal plane to adapt to barcode reading requirements in different directions. The design of the second rotating structure may be similar to the first rotating structure, but the direction and position of the rotation axis will differ. Similarly, a locking mechanism may be provided to ensure the stability of the barcode reader. The second rotating unit 3 can rotate along the C direction via the second sliding shaft 2.

[0030] The third rotating structure 4 is used to rotate the barcode reader on a third plane. The third plane is defined as a plane perpendicular to both the transmission plane and the transmission direction. In other words, through the third rotating structure 4, the barcode reader can be tilted up and down within the vertical plane. It should be noted that... Figure 1 and Figure 2 The third rotational structure 4 in the text is presented in the form of a non-rotational structure, that is to say Figure 1 and Figure 2 The third rotational structure can only achieve linear sliding; please refer to the subsequent related explanations. For the specific structure of the third rotational structure that can achieve rotational function, please refer to the first or second rotational structure.

[0031] The multi-directional adjustable barcode reader mounting bracket, through its complex adjustment structure, enables precise adjustment of the barcode reader across multiple planes. This enhances the reader's flexibility and adaptability, improving the accuracy and efficiency of barcode reading. Whether in complex production line environments or under space-constrained installation conditions, the bracket provides the optimal reading position and angle for the barcode reader.

[0032] In one possible implementation, the adjustment structure includes a first rotation structure; the first rotation structure includes a first rotation unit 6 and a first sliding shaft 5, the first sliding shaft 5 being perpendicular to a first plane, and the first rotation unit 6 being used to drive the barcode reader to rotate around the first sliding shaft 5 as the rotation center in the first plane.

[0033] In this embodiment, the adjustment structure is simplified to include only a first rotating structure. The first rotating structure is the key component for enabling the reader to rotate and adjust on a first plane. It combines the characteristics of rotation and sliding to ensure that the reader can be smoothly and accurately adjusted to the required rotation angle.

[0034] The first sliding shaft 5 is the fulcrum for the reader's rotation and is perpendicular to the first plane. The reader will rotate around this axis within the first plane. The design of the first sliding shaft 5 needs to be sufficiently robust to support the weight of the reader and ensure smooth rotation. In addition, the design of the sliding shaft also needs to consider ease of installation and disassembly for maintenance and replacement.

[0035] The first rotating unit 6 is the power source that drives the barcode reader to rotate around the first sliding shaft 5. Rotation may be achieved using a motor, a manual knob, or other drive mechanism. The design of the first rotating unit 6 needs to ensure the accuracy and stability of the rotation. For example, the motor may need to be equipped with an encoder to monitor the rotation angle in real time to ensure that the barcode reader can accurately adjust to the required rotation position. The manual knob may need to be designed with reasonable torque and damping for easy operation and to prevent damage. The first rotating unit 6 is bolted to the first sliding shaft 5, and a connecting bracket (first connecting plate) is provided at its end for mounting the barcode reader protective box 7.

[0036] In one possible implementation, the adjustment structure further includes a second rotation structure; the second rotation structure includes a second rotation unit 3 and a second sliding shaft 2, the first end of the second sliding shaft 2 is connected to the fixed base 1, the second sliding shaft 2 is perpendicular to the transmission plane, and the second rotation unit 3 is used to drive the code reader to rotate around the second sliding shaft 2 as the rotation center in the second plane.

[0037] In this embodiment, the adjustment structure is expanded to include a first rotating structure and a second rotating structure. These two rotating structures work together to achieve precise adjustment of the reader across multiple planes.

[0038] The second rotating structure is a key component for enabling the reader to rotate and adjust on the second plane. Similar to the first rotating structure, it combines the characteristics of rotation and sliding, but the plane and direction of rotation are different.

[0039] The second sliding shaft 2 serves as the fulcrum for the reader's rotation on the second plane. Perpendicular to the transmission plane, this means the reader will rotate horizontally around this axis. The design of the second sliding shaft 2 also needs to be sufficiently robust to support the weight of the reader and ensure smooth rotation. Bearings or other rotating mechanisms similar to those used on the first sliding shaft 5 may be employed to reduce friction and wear. Furthermore, the design of the sliding shaft must consider the connection method and installation accuracy with the fixed base 1 to ensure the accuracy and stability of the rotation. The first end of the second sliding shaft 2 is connected to the fixed base 1, ensuring the stability and reliability of the entire rotating structure. The connection method may employ bolts, welding, or other fastening mechanisms, depending on the application requirements and installation environment.

[0040] The second rotating unit 3 is the power source that drives the barcode reader to rotate around the second sliding shaft 2. Similar to the first rotating unit 6, it may use a motor, a manual knob, or other drive mechanism to achieve the rotation. The design of the second rotating unit 3 also needs to ensure the accuracy and stability of the rotation. The motor may need to be equipped with an encoder to monitor the rotation angle in real time, and the manual knob needs to be designed with reasonable torque and damping for easy operation.

[0041] For example, the second shaft rotation unit 3 is fixed on the second sliding shaft 2 by a bidirectional tightening device (second tightening device), and the end is provided with a second connecting plate 32 which is connected to the third rotating structure 4 by bolts.

[0042] In one possible implementation, the adjustment structure further includes a third rotation structure 4; the third rotation structure 4 includes a third rotation unit and a third sliding shaft, the first end of the third sliding shaft is connected to the second end of the second sliding shaft 2, the third sliding shaft is perpendicular to the second sliding shaft 2, and the third rotation unit is used to drive the code reader to rotate around the third sliding shaft as the rotation center in the third plane.

[0043] In this embodiment, the adjustment structure has been comprehensively expanded, including a first rotation structure, a second rotation structure, and a newly added third rotation structure 4. The three rotation structures work together to achieve precise omnidirectional adjustment of the barcode reader in three-dimensional space.

[0044] The third rotating structure 4 is a key component for enabling the barcode reader to rotate and adjust on the third plane. Similar to the first two rotating structures, it combines rotation and sliding characteristics, but the plane, direction, and fulcrum of rotation are different. The third sliding axis is the fulcrum for the barcode reader's rotation on the third plane. Perpendicular to the second sliding axis 2, this means the barcode reader will rotate around this new axis in a plane perpendicular to both the transmission plane and the transmission direction. The design of the third sliding axis also needs to be sufficiently robust to support the weight of the barcode reader and ensure smooth rotation. Because it is perpendicular to the second sliding axis 2, the design of the sliding axis requires special consideration of spatial layout and installation accuracy to ensure the accuracy and stability of rotation.

[0045] The first end of the third sliding shaft is connected to the second end of the second sliding shaft 2. This connection method ensures the continuity and stability of the entire rotating structure. The connection method may employ precision bearings, connectors, or other fastening mechanisms, depending on the application requirements and installation environment. The third rotating unit is the power source that drives the barcode reader to rotate around the third sliding shaft. Similar to the first and second rotating units 3, the rotation action may be achieved using a motor, manual knob, or other drive mechanism. The third sliding shaft in the third rotating structure has a first clamping pin 41 and a second clamping pin 42 at both ends, which are respectively connected and fixed to the second rotating unit 3 and the first sliding shaft 5.

[0046] It should be noted that the first rotating structure, the second rotating structure, and the third rotating structure 4 can all be set individually or in combination.

[0047] In one possible implementation, the first rotating unit 6 is fixed to the first sliding shaft 5 by a first tightening device. The first rotating unit 6 includes a first connecting plate 61 for mounting a barcode reader.

[0048] The first tightening device is a means for securely fixing the first rotating unit 6 to the first sliding shaft 5. The tightening device may be a bolt, nut, clamp, or other similar fastening mechanism. These devices ensure a tight connection between the first rotating unit 6 and the first sliding shaft 5 by applying appropriate torque, thereby preventing loosening or displacement during rotation. The first rotating unit 6 may be designed with an interface or hole that matches the first sliding shaft 5 so that it can be precisely mounted on the sliding shaft. The first tightening device is then used to secure these components together tightly. This fixing method ensures that the first rotating unit 6 can rotate smoothly and accurately around the first sliding shaft 5.

[0049] The first rotating unit 6 includes a specially designed connecting plate, namely the first connecting plate 61. This connecting plate is used to securely mount the barcode reader onto the first rotating unit 6. The connecting plate may have holes or interfaces that match the bottom of the barcode reader or the mounting bracket to enable precise mounting of the barcode reader.

[0050] In one possible implementation, the second rotating unit 3 is fixed to the second sliding shaft 2 by the second tightening device 31. The second rotating unit 3 includes a second connecting plate 32, which is used to connect the third sliding shaft and the second sliding shaft 2.

[0051] The second tightening device 31 refers to a device used to securely fix the second rotating unit 3 to the second sliding shaft 2. The second tightening device 31 may be a bolt, nut, clamping device or other similar fastening mechanism, which ensures a tight connection between the second rotating unit 3 and the second sliding shaft 2 by applying appropriate torque.

[0052] The second rotating unit 3 includes a specially designed connecting plate, namely the second connecting plate 32. This connecting plate serves to connect the third sliding shaft to the second sliding shaft 2, thereby forming a composite rotating structure. The second connecting plate 32 may have interfaces or holes that match the third sliding shaft and the second sliding shaft 2 to allow for precise connection of the two sliding shafts.

[0053] In one possible implementation, the third rotating unit is connected to the third sliding shaft via the bottom of the third tightening device, and the third rotating unit is connected to the first end of the first sliding shaft 5.

[0054] The third tightening device is a means for securely fixing the third rotating unit to the third sliding shaft. The tightening device may be a bolt, nut, clamp, or other similar fastening mechanism. These devices ensure a tight connection between the third rotating unit and the third sliding shaft by applying appropriate torque, thereby preventing loosening or displacement during rotation.

[0055] The third rotating unit is designed with an interface or hole that matches the third sliding shaft, allowing for precise installation on the sliding shaft. Then, a third tightening device is used to secure these components together tightly. This connection method ensures that the third rotating unit can rotate smoothly and accurately around the third sliding shaft. The third rotating unit is not only connected to the third sliding shaft but also has some form of connection to the first sliding shaft 5, thereby driving the first sliding shaft 5 to rotate.

[0056] In one possible implementation, the first rotating unit 6 is further configured to slide along the first sliding axis 5 to drive the barcode reader to slide along the direction of the first sliding axis 5; the second rotating unit 3 is further configured to slide along the second sliding axis 2 to drive the barcode reader to slide along the direction of the second sliding axis 2; and the third rotating unit is further configured to slide along the third sliding axis to drive the barcode reader to slide along the direction of the third sliding axis.

[0057] The first rotating unit 6 not only has the ability to rotate around the first sliding axis 5, but also to slide linearly along the direction of the first sliding axis 5. This design allows the barcode reader to maintain rotation around the first sliding axis 5 while also making linear displacement along that axis. To achieve this function, the first rotating unit 6 may incorporate a sliding mechanism, such as a linear guide, slider, or bearing. These mechanisms work closely with the first sliding axis 5 to ensure a smooth and precise sliding process.

[0058] The design principle of the second rotating unit 3 is similar to that of the first rotating unit 6, but it rotates around the second sliding axis 2 and has the function of sliding along this axis. This means that the barcode reader can not only be rotated and adjusted on the second plane, but also be linearly displaced along the direction of the second sliding axis 2. This design further enhances the flexibility of the barcode reader, enabling it to be adjusted in a wider range of spaces. Whether in the vertical or horizontal direction, the barcode reader can easily cope with various complex installation and scanning requirements.

[0059] The third rotating unit also possesses dual functions of rotation and sliding. It rotates around a third sliding axis and can slide along this axis. This design allows the reader to adjust rotation and linear displacement on a third plane, thereby meeting more diverse application requirements. Through the coordinated work of the first, second, and third rotating units, the reader can be adjusted omnidirectionally in three-dimensional space. Whether it is angle, height, or position, optimal configuration can be achieved through precise sliding and rotation.

[0060] Optionally, the sliding shaft in the rotating structure is cylindrical, but it can be designed in other shapes if only linear sliding is required.

[0061] In one possible implementation, the first rotating unit 6 further includes a reader protection box 7, which is used to install the reader to protect it.

[0062] The main purpose of the barcode reader protective box 7 is to provide a safe and stable installation environment for the barcode reader, while protecting it from interference and damage from the external environment. This includes, but is not limited to, preventing contaminants such as dust, moisture, and oil from entering the barcode reader, and reducing damage caused by mechanical impact or vibration.

[0063] Barcode reader protective cases are typically made of robust and durable materials, such as metals (e.g., stainless steel, aluminum alloy) or high-performance plastics. These materials not only possess sufficient strength and rigidity to resist external impacts and vibrations but also provide excellent sealing performance to prevent contaminants from entering. The structural design of the protective case usually takes into account the installation requirements and operating environment of the barcode reader. It may include mounting holes, interfaces, or brackets for securing the barcode reader, as well as a removable cover or door for easy maintenance and replacement of the barcode reader. Furthermore, the interior of the protective case may also contain shock-absorbing pads or cushioning materials to reduce the impact of vibration on the barcode reader.

[0064] Optionally, the barcode reader protective case 7 may be designed with a transparent window to allow observation of the barcode reader's operating status without opening the protective case. This facilitates real-time monitoring of the barcode reader's performance and scanning quality while avoiding direct exposure of the barcode reader to potentially hazardous environments.

[0065] In summary, the technical solution provided by this utility model, through at least one of the first, second, or third rotating structures, drives the barcode reader to rotate within the plane corresponding to the first, second, or third rotating structure, thus enriching the rotation angle of the barcode reader and making it suitable for more production environments. Furthermore, while adding the rotation function, the linear sliding function is still present, providing diverse adjustment methods.

[0066] Those skilled in the art will understand that Figure 1 and Figure 2 The structure shown does not constitute a limitation on the structure of this utility model. It may include more or fewer components than shown, or combine certain components, or use different component arrangements.

[0067] It should be understood that "multiple" as used in this article refers to two or more.
