Technical Field

[0001] The utility model relates to the technical field of projection screens, in particular to an automatic ironing device for holes in a screen. Background Art

[0002] With the advancement of technology and people's increasing requirements for audio-visual experience, projection screens are increasingly used in various conferences, teaching, home theaters and other occasions. In order to solve the problem of ensuring the sound transmission performance of the screen, screen manufacturers have been committed to reducing the size of the sound transmission holes in recent years, so as to maximize the light reflection performance and imaging clarity of the screen while ensuring the sound transmission performance. However, simply reducing the size of the hole is not enough to solve all problems, and the alignment accuracy of the sound transmission hole is also crucial.

[0003] In the production process of projection screens, the screen is usually spliced ​​from multiple small-sized substrates. In order to ensure the integrity and quality of the picture, the holes between these substrates need to be accurately aligned and ironed. However, the existing production methods mostly rely on manual operations for hole alignment and ironing, which is inefficient and prone to errors. Therefore, an automatic screen hole alignment and ironing device is now needed to solve the above problems. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] See also Figure 1-4The utility model provides a technical solution: an automatic screen hole ironing device, comprising a support component 1, a lifting and pressing component 2 and an ironing device 3. The support component 1 comprises a support base 11, four groups of limit fixing blocks 12 are fixed on the upper end of the support base 11, and a substrate 4 to be ironed is placed between the four groups of limit fixing blocks 12. The upper end of the support component 1 is equipped with a lifting and pressing component 2, and the lower end of the lifting and pressing component 2 is equipped with an ironing device 3. The ironing device 3 is perpendicular to the substrate 4 to be ironed. The support base 11 carries all the components to ensure the stability and reliability of the device. The four groups of limit fixing blocks 12 form a frame to accurately position the substrate in the frame to prevent the substrate from moving or offsetting during the ironing process, thereby ensuring the accurate alignment of the hole positions. The lifting and pressing component 2 is installed at the upper end of the support component 1, and its main function is to control the movement of the ironing device 3. The function of the ironing device 3 is to perform the ironing operation.

[0019] The upper end of the limiting and fixing block 12 is in the form of an inclined surface, and the design of the inclined surface makes it easier for the substrate 4 to be ironed to slide into the space between the limiting and fixing blocks 12 when placed.

[0020] A support bracket 13 is fixed to the upper end of the support base 11, and the lifting and pressing assembly 2 includes a linear slide rail 21, which is fixed to the side of the support bracket 13. The linear slide rail 21 is fixed to the side of the support bracket 13 to ensure the stability of the ironing device 3 during the lifting process.

[0021] Two sets of sliders 22 are slidably mounted on the linear slide rail 21 . The two sets of sliders 22 are fixedly mounted on the right side of the ironing device 3 . The sliders 22 provide stable support for the ironing device 3 and effectively prevent it from shaking back and forth during operation.

[0022] A lifting cylinder 23 is installed at the upper end of the support bracket 13, and a lifting base 25 is provided at the lower end of the lifting cylinder 23. The lifting base 25 is fixedly installed on the upper end of the ironing device 3. The lifting cylinder 23 provides a stable and reliable lifting power source for the lifting movement of the ironing device 3.

[0023] Guide rods 24 are arranged on both sides of the lifting cylinder 23. The guide rods 24 are movably mounted on the upper end of the support bracket 13. The lower ends of the guide rods 24 are fixed to the lifting base 25. The function of the guide rods 24 is to prevent the lifting base 25 and the ironing device 3 from shaking left and right during the lifting process.

[0024] As an embodiment of the utility model: when the automatic ironing device for screen hole alignment is used, the substrate 4 to be ironed is first placed between the four groups of limit fixing blocks 12. Since the upper ends of the limit fixing blocks 12 are designed with inclined surfaces, the substrate can more easily slide into the space between the fixing blocks to achieve fast and accurate positioning; the support base 11 serves as the basis of the entire device and carries all components; the lifting cylinder 23 serves as a power source to drive the lifting base 25 and the ironing device 3 fixed thereon to perform lifting movements, and the setting of the guide rod 24 ensures the stability of the lifting base 25 and the ironing device 3 during the lifting process. The two sets of sliders 22 drive the ironing device 3 to move up and down along a predetermined trajectory under the guidance of the linear slide rail 21; when the ironing device 3 descends to a position perpendicular to the substrate 4 to be ironed, the ironing operation begins, and the ironing device 3 uses its internal heating element to heat and iron the substrate to achieve fixation and alignment of the substrate; during the whole process, due to the synergistic effect of the lifting and pressing assembly 2 and the supporting assembly 1, the lateral force on the substrate is reduced by vertical pressing, thereby avoiding the problem of substrate movement and hole misalignment that may be caused during flat ironing.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
