[0025] like Figure 1 As shown in the embodiment, a positioning control device for installing small-sized displays includes: a base plate 1, an XYZR axis displacement platform 2, an electric suction cup 7, and a mounting platform 5. The base plate 1 is placed at the bottom of the device; the XYZR axis displacement platform 2 is mounted on the base plate 1; the electric suction cup 7 is mounted on the XYZR axis displacement platform 2; and the mounting platform 5 is placed at the top of the device. The base plate 1, as the fundamental support component of the entire positioning control device, possesses high strength and stability to ensure the stability of the device during operation. The XYZR axis displacement platform 2 has precise movement capabilities in three linear directions (X, Y, Z axes) and one rotational direction (R axis), and can flexibly adjust the position and angle of the electric suction cup 7 according to actual installation requirements. The electric suction cup 7, through its strong suction force, can firmly adhere to the small-sized display screen, ensuring that the display screen will not shift or fall during installation. The mounting platform 5 provides a precise installation reference surface for the small-sized display screen, enabling the display screen to be accurately installed in the designated position, achieving a high-precision positioning and installation effect.

[0026] like Figure 1 As shown, in some embodiments of this utility model, the base plate 1 and the mounting platform 5 are connected by a column 3. The column 3 is made of high-strength material, has good load-bearing capacity and deformation resistance, and can stably support the mounting platform 5, ensuring that the mounting platform 5 remains horizontal during equipment operation and will not tilt or shake due to force, thereby further ensuring the accuracy and stability of the installation of small-sized display screens.

[0027] like Figure 1As shown, in some embodiments of this utility model, the base plate 1 and / or the mounting platform 5 are rectangular, and the columns 3 comprise four sets, respectively disposed at the four corners of the base plate 1 and / or the mounting platform 5. This design layout makes the structure of the entire positioning control device more stable. The four sets of columns 3 are evenly distributed at the four corners, effectively dispersing and bearing forces from all directions, further enhancing the device's resistance to deformation and shaking. Furthermore, this openwork design on all four sides allows the operator to conveniently operate from any angle without obstruction or obstruction, greatly improving ease of use and flexibility.

[0028] like Figure 1 As shown, in some embodiments of this utility model, the bottom of the column 3 is fixedly connected to the base plate 1, the top of the column 3 is connected to the mounting platform 5 by locking screws 6, and a disc spring 4 is provided between the top of the column 3 and the mounting platform 5. The disc spring 4 is located between the column 3 and the mounting platform 5. When compressed, its height decreases until it is fully compressed; when the compression is relieved, its height increases until it is fully restored. The locking screw 6 has a rotating handle, which can be rotated to adjust the tightness or looseness of the locking screw 6, thereby indirectly adjusting the compression degree of the disc spring 4. That is, tightening the locking screw 6 increases the compression degree of the disc spring 4 until it is fully compressed; loosening the locking screw 6 decreases the compression degree of the disc spring 4 until it is completely uncompressed. This adjusts the height of the mounting platform 5 at the disc spring 4. By adjusting the tightness or looseness of the four locking screws 6, the orientation of the mounting surface of the small-sized display on the mounting platform 5 can be adjusted, achieving parallelism control of the installation.

[0029] like Figure 1 As shown, in some embodiments of this utility model, the degrees of freedom of the XYZR axis displacement platform 2 include displacement along the X, Y, and Z axes and 360° rotation along the Z axis. The XYZR axis displacement platform 2 is a commercially available mature component, equipped with a micrometer, which can be manually adjusted as needed to achieve high-precision displacement along the X, Y, and Z axes and 360° rotation along the Z axis of the workpiece mounted on this platform.

[0030] like Figure 1 As shown, in some embodiments of this utility model, the electric suction cup 7 has a suction cup mounting plate 8 at its bottom, and the XYZR axis displacement platform 2 has an adapter plate 9 that matches the suction cup mounting plate 8. The suction cup mounting plate 8 and the adapter plate 9 are connected by screws. The function of the suction cup mounting plate 8 and the adapter plate 9 is to solve the problem that the electric suction cup 7 and the XYZR axis displacement platform 2 cannot be directly installed due to incompatible mounting interfaces, and to provide a mounting adapter.

[0031] like Figure 1As shown, in some embodiments of this utility model, an installation window is provided on the mounting platform 5 corresponding to the suction cup position of the electric suction cup 7. The size of the installation window is adapted to the display area of ​​the display screen, ensuring that the electric suction cup 7 can be installed accurately and securely through this window. At the same time, the edges of the installation window are finely polished, smooth and burr-free, avoiding scratches or other damage to the electric suction cup 7 or the display screen during installation, ensuring the safety and reliability of the entire installation process.

[0032] like Figure 1 As shown, in some embodiments of this utility model, the mounting platform 5 is provided with a positioning structure. This positioning structure can be a positioning hole, which is set at a specific position on the mounting platform 5. Through the precise matching of the display panel with the positioning hole, the display panel can be quickly and accurately positioned to the predetermined position on the mounting platform 5, greatly improving installation efficiency and accuracy, and reducing errors and adjustment time caused by inaccurate positioning during installation.

[0033] In use, first place the device on the working platform of the 2D image measuring instrument, turn on the instrument and keep it in the ready-to-work state. First, place the panel of the small-sized display (such as an airborne digital image source) to be installed on the mounting platform 5, aligning the display panel with the installation window, and tighten the positioning holes with the mounting screws to achieve precise positioning. Then, use the 2D image measuring instrument to measure the window center coordinates (X, Y directions) of the aforementioned small-sized display panel. Next, place the display screen with protective glass (the display screen is already bonded to the protective glass) into the installation area of ​​the aforementioned display panel. Manually raise the height of the XYZR axis displacement platform 2 (Z direction) so that the suction nozzle of the electric suction cup 7 contacts the protective glass of the display screen, and turn on the electrical switch. Use the vacuum environment created by suction to hold the protective glass of the display screen. Turn on the power to the display screen and light it up. Use the 2D image measuring instrument to measure the display center coordinates (X, Y directions) of the display screen. Based on the previously measured window center coordinates of the display panel and the display center coordinates of the display screen... The XYZR axis displacement platform 2 is manually adjusted along the X and Y directions to ensure that the center coordinates of the display screen coincide with or meet the tolerance requirements of the window center coordinates of the display panel, thus completing the X and Y direction positioning of the display screen installation. A two-dimensional image measuring instrument is used to measure the parallelism between the display image surface of the display screen and the display mounting surface on the mounting platform 5. Based on the measurement results, the tightness or looseness of the four locking screws 6 is manually adjusted, and the parallelism value between the display image surface and the display mounting surface is simultaneously measured using the two-dimensional image measuring instrument. Continuous adjustments and corrections are made to ensure that the display image surface and the display mounting surface are parallel or that the parallelism meets the tolerance requirements, thus completing the parallelism control of the display screen installation. The distance between the display image surface of the display screen and the display mounting surface on the mounting platform 5 is measured using the two-dimensional image measuring instrument. Based on the measurement results, the XYZR axis displacement platform 2 is manually adjusted along the Z direction to ensure that the distance between the display image surface and the display mounting surface meets the requirements, thus completing the Z direction positioning of the display screen installation. The roll angle between the center line of the display screen and the center line of the display panel opening is measured using a two-dimensional image measuring instrument. Based on the measurement results, the XYZR axis displacement platform 2 is manually rotated along the Z axis to ensure that the roll angle between the center line of the display screen and the center line of the display panel opening meets the requirements, thus completing the roll angle control of the display screen installation.
