Detailed Implementation

[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0021] like Figure 1 and Figure 3 As shown, an installation and positioning tool for an RGV trolley reader includes: a bracket 1, on which a reader positioning block 2 is mounted, and on which a first positioning surface 3 is mounted; a first adjusting bolt 4 and a second adjusting bolt 5 are mounted on the bracket 1, the adjustment directions of the first adjusting bolt 4 and the second adjusting bolt 5 being perpendicular to each other. The bracket 1 is a U-shaped frame, and a waist-shaped hole 11 is provided on one side wall of the bracket 1. A third adjusting bolt 12 passes through the reader positioning block 2 and the waist-shaped hole 11 and is locked in place by a nut, used for fixing and vertically adjusting the reader positioning block 2. The bracket 1 slides on a guide rail 6, and the second adjusting bolt 5 passes through the other side wall of the bracket 1 and contacts the guide rail 6, used for adjusting the position of the reader positioning block 2 relative to the QR code strip 7 on the guide rail 6. An adjusting plate 10 is provided on the bracket 1, and the adjusting plate 10 is provided with the first adjusting bolt 4 for adjusting the distance between the bracket 1 and the RGV trolley wheel frame 8. It also includes a second positioning surface 9, which cooperates with the first positioning surface 3 to position the reader. The second positioning surface 9 and the first positioning surface 3 are arranged perpendicularly to each other. The first adjusting bolt 4, the second adjusting bolt 5, and the third adjusting bolt 12 are perpendicular to each other in their respective directions. There are at least two of the first adjusting bolt 4, the second adjusting bolt 5, and the third adjusting bolt 12. The first adjusting bolt 4, the second adjusting bolt 5, and the oblong hole 11 are all provided with graduations. The ends of the first adjusting bolt 12 and the second adjusting bolt 42 are provided with buffer layers.

[0022] The support frame 1 adopts a U-shaped frame structure, with oblong holes 11 and adjusting bolt holes on both side walls. As the basic support structure of the entire positioning tool, it supports components such as the reader positioning block 2 and adjusting bolts. The U-shaped design provides stable mechanical support, ensuring that the tool does not deform during positioning. The oblong hole 11 on one side wall, in conjunction with the third adjusting bolt 12, enables vertical adjustment of the reader positioning block 2. The adjusting bolt hole on the other side wall is used to install the second adjusting bolt 5, adjusting the horizontal distance between the reader and the QR code strip 7 on the guide rail 6. The U-shaped structure ensures the rigidity of the tool, reducing positioning deviations caused by external forces. The combination of the oblong holes and adjusting bolts allows for a wider vertical adjustment range and greater adaptability. It provides a stable platform for the installation and adjustment of other components. The reader positioning block 2 is connected to the support frame 1, with a first positioning surface 3 and a second positioning surface 9 on its surface. The first positioning surface 3 and the second positioning surface 9 contact the reader, achieving precise positioning of the reader. The first positioning surface 3 and the second positioning surface 9 are perpendicular to each other, forming a rectangular coordinate system, ensuring the accurate position of the reader in two vertical directions. The third adjusting bolt 12 passes through the reader dock positioning block 2 and the oblong hole 11, achieving vertical fixation and adjustment. The design of two vertical positioning surfaces precisely limits the installation position of the reader dock in the plane, avoiding positioning errors caused by a single reference point in traditional installation. The adjustable vertical position adapts to the height differences of different reader dock models or installation environments. The first positioning surface 3 is located on the reader dock positioning block 2 and has a planar structure. As one of the main positioning surfaces of the reader dock, it fits with the corresponding surface of the reader dock to determine the position of the reader dock in one direction. It cooperates with the second positioning surface 9 to form orthogonal positioning, ensuring the accurate position of the reader dock in two vertical directions. The planar positioning surface design provides a larger contact area, reducing positioning instability caused by insufficient contact points. In conjunction with the second positioning surface 9, it achieves precise positioning of the reader dock in a two-dimensional plane, improving installation accuracy. The first adjusting bolt 4 passes through the adjusting plate 10 of the bracket 1, with a buffer layer at the end. It adjusts the distance between the bracket 1 and the RGV trolley wheel frame 7 to ensure the accurate relative position of the reader dock and the wheel frame. The adjustment direction is perpendicular to the second adjusting bolt 5 and the third adjusting bolt 12, forming a three-dimensional adjustment system. The buffer layer reduces wear on the contact surface during adjustment, protecting components. The three-dimensional adjustment system allows for fine-tuning of the reader's installation position in three orthogonal directions, adapting to different installation needs. The buffer layer extends the service life of components and reduces maintenance costs. The second adjusting bolt 5 passes through the other side wall of the bracket 1, contacts the guide rail 6, and has a buffer layer at its end. Adjusting the horizontal distance between the reader's positioning block 2 and the QR code strip 7 on the guide rail 6 ensures the reader can accurately read QR code information. In conjunction with the first adjusting bolt 4 and the third adjusting bolt 12, three-dimensional adjustment is achieved. The buffer layer protects the guide rail surface, preventing scratches or damage during adjustment.Precise horizontal adjustment ensures the optimal reading distance between the reader and the QR code strip, improving the accuracy and stability of information reading. The integrity of the three-dimensional adjustment system allows for omnidirectional adjustment of the reader's installation position, adapting to complex installation environments. The guide rail 6 serves as the track for the RGV trolley, with a QR code strip 7 on its surface. This provides the RGV trolley with a running path, ensuring its movement along the fixed track. The QR code strip 7 acts as a position marker; the reader determines the trolley's position by reading the QR code information. The second adjusting bolt 5 contacts the guide rail, and its position determines the horizontal distance between the reader and the QR code strip. The fixed track design ensures the stability and repeatability of the RGV trolley's operation. The QR code strip provides a precise position reference for the trolley, and combined with the precise positioning of the reader, improves the overall system's positioning accuracy. The QR code strip 7, a strip-shaped marker containing a QR code pattern, is affixed or fixed to the surface of the guide rail 6. Serving as a position marker for the RGV trolley, the reader obtains the trolley's real-time position information by scanning the QR code strip. The accuracy of its position directly affects the installation and positioning of the reader dock, therefore, the horizontal distance between the reader dock and the QR code strip needs to be adjusted using the second adjusting bolt 5. QR code technology provides high-density positional information, enabling the RGV trolley to achieve millimeter-level positioning accuracy. Used in conjunction with positioning tools, this ensures that the reader dock can be accurately aligned with the QR code strip during installation, avoiding misjudgments due to installation deviations. The adjusting plate 10 is fixed to the bracket 1 and has holes for installing the first adjusting bolt 4. Serving as the mounting carrier for the first adjusting bolt 4, the distance between the bracket and the RGV trolley wheel frame 7 is changed by adjusting the position of the bolt. The design of the adjusting plate enhances the structural strength of the bracket and distributes the force on the adjusting bolt. The adjustable spacing design adapts to the size differences of different RGV trolley wheel frames, improving the versatility of the positioning tools. The enhanced structural strength ensures the stability of the bracket during adjustment, preventing deformation or damage caused by uneven force. The second positioning surface 9 is located on the reader dock positioning block 2 and is perpendicular to the first positioning surface 3. As another positioning surface of the reader dock, it forms an orthogonal positioning system together with the first positioning surface 3. The orthogonal positioning system ensures accurate positioning of the reader dock not only in one direction but also precisely constrained in the vertical direction during installation. This eliminates potential rotation or offset during installation, improving accuracy. The combined use of two positioning surfaces provides double constraint on the reader dock's installation position within a two-dimensional plane, further enhancing positioning precision. A long, narrow hole 11 is located on one side wall of the bracket 1. This hole, in conjunction with the third adjusting bolt 12, allows for vertical movement and fixation of the reader dock positioning block 2. The elongated design of the hole allows for free adjustment of the positioning block within a certain range, adapting to installation requirements at different heights. This vertical adjustability enables the positioning tool to adapt to different reader dock models or varying installation environments, improving its flexibility and applicability.The third adjusting bolt, used in conjunction with the third adjusting bolt, enables rapid adjustment and fixation of the positioning block, improving installation efficiency. The third adjusting bolt 12 passes through the reading dock positioning block 2 and the oblong hole 11, and is locked with a nut. Adjusting the vertical height of the reading dock positioning block 2 ensures accurate relative height between the reading dock and the RGV trolley. The oblong hole 11 allows for vertical movement and fixation of the positioning block. The locking nut ensures stable positioning of the adjusted block, preventing loosening during use. Precise vertical adjustment ensures height matching between the reading dock and the trolley, avoiding reading errors or mechanical interference due to height deviations. The quick-locking function improves installation efficiency and reduces time wasted on repeated adjustments.
