Description

A spliced ​​air-floating platform and inkjet printing equipment for display panel processing

Technical field

[0001] The present application relates to the technical field of display panel processing, and in particular to a spliced ​​air floating platform and inkjet printing equipment for display panel processing. [Background Technology]

[0002] Inkjet printing technology has been widely used in many traditional fields. In recent years, it has also been gradually applied to flexible devices such as OLED, RFID, and thin-film solar cells. Flexible electronics manufacturing processes that combine flexible electronics with inkjet printing are gaining more attention.

[0003] When printing on flexible panels, the use of air flotation conveying technology for contactless transport of glass can effectively avoid scratches on the panel and reduce defects caused by printing.

[0004] When processing large-size panels, such as the 1500 x 1850 mm panels produced on the G6 production line, the required air flotation platform must be sized to support the large panels. Large air flotation platforms require guaranteed flatness on their air outlet surfaces to ensure the flatness of the panels supported by the platform and maintain accurate printing.

[0005] In the prior art, large-scale air flotation platforms are typically constructed using multiple layers of large aluminum plates with air holes and flow channels placed between them to form a monolithic air flotation platform. However, this monolithic air flotation platform requires specialized design, and the air flotation height of each area on the platform cannot be adjusted individually. Furthermore, because aluminum plates are easily deformed, it is difficult to machine large-scale surfaces that meet the required precision for air flotation. This necessitates the use of a large array of adjustment screws to locally deform the aluminum plates to adjust the flatness of the air flotation working surface. This adjustment method is time-consuming and labor-intensive, and the effectiveness of the adjustment cannot be guaranteed.

[0006] Some other approaches utilize larger marble slabs as the main body of the air flotation platform, with air holes machined into the marble to support the large-scale air flotation platform. While marble can be machined into a highly precise surface, this requires sufficient thickness, which makes the air flotation platform heavy and hinders its usability. Furthermore, marble platforms are not suitable for complex air hole structures, making it difficult to ensure effective air flotation conveying.

[0007] Therefore, there is a need for an air flotation platform that can be freely designed, easily adjusted, easily ensures the accuracy of the air flotation surface, and has adjustable air flotation partitions to meet the needs of high-precision air flotation transportation of large-sized substrates.

[0008] [Summary of the invention]

[0009] The embodiments of the present application provide a spliced ​​air flotation platform and inkjet printing equipment for display panel processing, so as to solve the technical problems in the related art that the flatness of the air outlet surface of the air flotation platform made of a whole marble slab is difficult to ensure, and the flatness of the subsequent air outlet surface cannot be adjusted, which affects the printing processing quality of the panel.

[0010] In a first aspect, a spliced ​​air flotation platform for display panel processing is provided, comprising a mounting platform and a plurality of air flotation modules, wherein the plurality of air flotation modules are evenly mounted on a top surface of the mounting platform, with installation gaps left between adjacent air flotation modules, and a plurality of height adjustment mechanisms, wherein the height adjustment mechanisms include:

[0011] A fixing block, each of the air flotation modules is fixed with a plurality of the fixing blocks, the plurality of fixing blocks fixed to the air flotation modules are dispersedly arranged, the fixing blocks are fixed to the sides of the air flotation modules, and some of the fixing blocks are located in the installation gap;

[0012] An adjusting screw is vertically inserted into the fixing block and is threadedly connected to the fixing block, and the adjusting screw is rotatably connected to the mounting platform; wherein,

[0013] The height of the fixed block relative to the mounting platform is changed by rotating the adjusting screw, so as to adjust the height of the air flotation module relative to the mounting platform.

[0014] In some embodiments, the height adjustment mechanism further includes a locking assembly, wherein the locking assembly includes:

[0015] A plurality of locking blocks, each of which is movably connected to the fixed block, and a clamping space for the adjusting screw to pass through is reserved between the locking blocks, the adjusting screw passes through the clamping space, and the locking blocks include a matching inclined surface;

[0016] A plurality of locking screws, each of the locking screws corresponds to a plurality of locking blocks, the locking screws vertically pass through the fixing block and are threadedly connected to the fixing block, and the locking screws include a pushing inclined surface; wherein,

[0017] As the locking screw descends, the pushing inclined surface pushes the matching inclined surface, so that the locking block is pressed against the circumferential side surface of the adjusting screw.

[0018] In some embodiments, a locking groove is formed on a side surface of the locking block, a groove wall of the locking groove fits with a side surface of the adjusting screw, and the locking groove is pressed against the side surface of the adjusting screw.

[0019] In some embodiments, a through receiving groove is formed on a side surface of the fixing block, and the plurality of locking blocks are located in the receiving groove.

[0020] In some embodiments, a connecting strip is provided at the bottom end of the locking block, and the locking block is connected to the fixing block via the connecting strip; wherein,

[0021] As the locking screw pushes the locking block, the connecting strip is deformed to support the movement of the locking block and press against the adjusting screw.

[0022] In some embodiments, the height adjustment mechanism also includes a connecting bolt, the adjusting screw is provided with a penetrating countersunk hole along its center line, the connecting bolt is passed through the adjusting screw through the countersunk hole, and the connecting bolt is threadedly connected to the mounting platform, and the head of the connecting bolt is tightly pressed against the step surface of the countersunk hole.

[0023] In some embodiments, the air flotation module includes:

[0024] a mounting plate, the height adjustment mechanism being connected to a side surface of the mounting plate;

[0025] A plurality of air floating blocks are evenly fixed on the mounting plate, and the air outlet surfaces of the plurality of air floating blocks are in the same plane.

[0026] In some embodiments, the spliced ​​air-floating platform for display panel processing further includes a shielding component, wherein the shielding component includes a plurality of shielding bars;

[0027] The air flotation blocks are in the shape of long strips. In the length and width directions of the air flotation blocks, multiple air flotation blocks are evenly spaced. The shielding strips are fixed to the mounting platform and / or the mounting plate, and are used to shield the gaps between adjacent air flotation blocks.

[0028] In some embodiments, the mounting plate comprises a marble plate.

[0029] The beneficial effects of the technical solution provided by this application include:

[0030] The present invention provides a spliced ​​air flotation platform for display panel processing. Because the platform is composed of multiple air flotation modules, each module has a relatively small outlet surface, making it easier to control the flatness of the outlet surface during processing. Smaller modules are also less likely to deform and affect the flatness of their outlet surfaces. Furthermore, the modules can be adjusted in height using height adjustment mechanisms. When the modules are mounted on a mounting platform, the outlet surfaces can be adjusted to a horizontal position using the multiple height adjustment mechanisms. The height adjustment mechanisms can also be used to align the outlet surfaces of multiple modules, ensuring the flatness of the outlet surface of the spliced ​​platform. Even if the outlet surfaces of different modules subsequently vary in height or angle, the height adjustment mechanisms can still be used to align the outlet surfaces of the modules, ensuring the flatness of the display panel while on the platform and improving the processing quality of the display panel.

[0031] In addition, only an installation gap is left between adjacent air flotation modules, and the support gap caused by adjacent air flotation modules is small. The distribution density of the air flotation modules is large, so the air outlet distribution density of the air flotation platform is large, and there is no large air-out area on the air flotation platform, so that the supporting force applied to the display panel is more uniform. When the display panel is on the air flotation platform, the various parts of the display panel are evenly stressed, and the flatness of the display panel is better, thereby improving the accuracy of the inkjet printing processing of the display panel and improving the printing quality of the display panel.

[0032] Due to the setting of the installation gap between the flotation modules, it is convenient to accommodate the height adjustment mechanism. After multiple flotation modules are installed on the mounting table, the height of the fixed block can still be adjusted by extending the tool into the installation gap in the vertical direction to operate the adjustment screw, which supports the adjustment of the flatness and height of the air outlet surface of the flotation module, making it convenient to adjust multiple air flotation modules to a state where the air outlet surfaces are in the same plane.

[0033] In a second aspect, an inkjet printing device is provided, comprising the spliced ​​air floating platform for display panel processing as described above.

[0034] Another embodiment of the present application provides an inkjet printing device. Since the inkjet printing device includes the above-mentioned spliced ​​air flotation platform for display panel processing, the inkjet printing device also has the beneficial effects of the above-mentioned spliced ​​air flotation platform for display panel processing, which will not be repeated here.

[0045] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] The present invention provides a modular air flotation platform and inkjet printing equipment for display panel processing. The modular air flotation platform is constructed from multiple air flotation modules, and the horizontality and flatness of the air outlet surfaces of the modules can be adjusted via a height adjustment mechanism to ensure the flatness of the air flotation platform's outlet surface. This improves the precision and quality of inkjet printing on display panels. This application addresses the technical problem in related art where the flatness of the outlet surface of air flotation platforms fabricated from a single marble slab is difficult to ensure, and the subsequent flatness of the outlet surface cannot be adjusted, thus affecting the quality of inkjet printing on the panel.

[0047] Referring to Figures 1 and 2, a spliced ​​air flotation platform for display panel processing includes a mounting platform 1 and multiple air flotation modules 2. Each of the air flotation modules 2 is mounted on the top surface of the mounting platform 1 and evenly distributed across the top surface. The top surfaces of the air flotation modules 2 serve as the air outlet surface. When the evenly distributed air flotation modules 2 are spliced ​​together to form the air flotation platform, they provide more uniform and comprehensive support for the display panel, ensuring even force on the display panel and improving the flatness of the supported display panel.

[0048] 1 and 2 , further, an installation gap a is left between adjacent air flotation modules 2. Since there is a spacing between the multiple air outlet holes of the air flotation modules 2, by providing the installation gap a between adjacent air flotation modules 2, after the air flotation modules 2 are spliced, the multiple air outlet holes of the multiple air flotation modules 2 can be distributed more evenly. When supporting the display panel, the multiple support points of the display panel are distributed more evenly, thereby improving the flatness of the display panel when supported by the air flotation platform.

[0049] Referring to Figures 1-3, the spliced ​​air flotation platform for display panel processing also includes multiple height adjustment mechanisms 3. Each air flotation module 2 is connected to the mounting platform 1 by multiple height adjustment mechanisms 3. Each air flotation module 2 can adjust the level and height of its outlet surface via the multiple height adjustment mechanisms 3. This allows the outlet surfaces of multiple air flotation modules 2 to be adjusted to a consistent height and maintain the same horizontal plane. Therefore, when the air flotation platform, composed of multiple air flotation modules 2, supports a display panel, the height of each display panel at different locations can be maintained, improving the flatness of the supported display panel.

[0050] Referring to Figures 3-5, the height adjustment mechanism 3 includes a fixed block 31 and an adjustment screw 32. Each flotation module 2 is fixed with multiple fixed blocks 31, and multiple fixed blocks 31 are dispersed on the side of the flotation module 2. Specifically, the fixed blocks 31 are fixed to the flotation module 2 via multiple bolts or screws. The adjustment screw 32 is vertically inserted through the fixed block 31 and is threadedly connected to the fixed block 31. The adjustment screw 32 is rotatably connected to the mounting platform 1. By rotating the adjustment screw 32, the fixed block 31 can be driven to move in the vertical direction to adjust the height of the position where the fixed block 31 is installed in the flotation module 2.

[0051] Referring to Figures 3-5, specifically, the height adjustment mechanism 3 also includes a connecting bolt 34. A countersunk hole is provided on the top surface of the adjusting screw 32 along its centerline. The connecting bolt 34 passes through the countersunk hole and is threadedly connected to the mounting platform 1. The head of the connecting bolt 34 abuts against the stepped surface of the countersunk hole. The adjusting screw 32 can be rotatably connected to the mounting platform 1 via the connecting bolt 34. Before rotating the adjusting screw 32, the abutment between the connecting bolt 34 and the stepped surface of the countersunk hole is first released. After rotating the adjusting screw 32 to adjust the level and height of the air flotation platform, the connecting bolt 34 is tightened so that its head abuts against the stepped surface of the countersunk hole, thereby limiting the rotation of the adjusting screw 32.

[0052] In this configuration, since the air flotation module 2 is fixed with multiple fixing blocks 31 , the height of different positions of the air flotation module 2 can be adjusted by adjusting the height of different fixing blocks 31 , thereby facilitating adjusting the air outlet surface of the air flotation module 2 to be horizontal.

[0053] Referring to Figures 2-5, in this embodiment, the flotation module 2 is arranged in a cubic shape, and multiple flotation modules 2 are spaced apart in the length and width directions of the flotation module 2. In other embodiments, the flotation module 2 can also be cylindrical or have other shapes. In this embodiment, each flotation module 2 is connected to the mounting platform 1 by four height adjustment mechanisms 3, and the four height adjustment mechanisms 3 are distributed in pairs on two opposite sides of the flotation module 2, and the four height adjustment mechanisms 3 are respectively arranged near the four corners of the bottom surface of the flotation module 2. Therefore, by adjusting the height of the four corners of the flotation module 2 respectively through the four height adjustment mechanisms 3, it is easier to adjust the air outlet surface of the flotation module 2 to a horizontal position.

[0054] 3-5 , the fixing block 31 is fixed to the side of the air flotation module 2 , and the fixing block 31 is located in the installation gap a between adjacent air flotation modules 2 , with opposite sides of the fixing block 31 respectively abutting against two adjacent air flotation modules 2 .

[0055] With this arrangement, after multiple air flotation modules 2 are arranged on the mounting platform 1, the height adjustment mechanism 3 is positioned within the mounting gap a as the air flotation modules 2 are joined. To adjust the height and level of the air outlet surfaces of the air flotation modules 2, and to align the outlet surfaces of the multiple air flotation modules 2, the air flotation modules 2 can be adjusted by inserting a tool such as a screw or wrench into the mounting gap a and turning the adjustment screw 32.

[0056] The installation gap a within which the fixing block 31 is located is relatively narrow. However, because the adjustment screw 32 for adjusting the height of the fixing block 31 is vertically inserted through the fixing block 31 and rotates in the horizontal plane, even with a relatively narrow installation gap a, the height of the fixing block 31 can still be easily adjusted, thereby adjusting the levelness and height of the outlet surface of the air flotation module 2.

[0057] 3-5 , in order to facilitate the rotation of the adjusting screw 32 , a slot or a cross slot is provided on the top surface of the adjusting screw 32 to facilitate the rotation of the adjusting screw 32 by a screwdriver.

[0058] The height adjustment mechanism 3 further includes a locking assembly 33 , which includes a plurality of locking blocks 331 and a plurality of locking screws 332 .

[0059] Referring to Figures 3-5 , multiple locking blocks 331 are movably connected to the fixed block 31, and a clamping space is left between the locking blocks 331 for the adjustment screw 32 to pass through. The adjustment screw 32 passes through the clamping space, and the locking blocks 331 include a matching bevel 331c. The matching bevel 331c is arranged at an angle to the horizontal plane.

[0060] 3 to 5 , a plurality of locking screws 332 correspond one to one with a plurality of locking blocks 331. The locking screws 332 are vertically passed through the fixed block 31 and are threadedly connected to the fixed block 31. The locking screws 332 include a pushing bevel 332a. The pushing bevel 332a is arranged to be inclined relative to the horizontal plane. In this embodiment, the locking screw 332 includes a countersunk screw having a truncated cone-shaped head, that is, the circumferential side surface of the head of the countersunk screw is the pushing bevel 332a. In other embodiments, the locking screw 332 includes a truncated cone section, and the circumferential side surface of the truncated cone section is the pushing bevel 332a.

[0061] With this arrangement, by rotating the locking screw 332, the locking screw 332 moves vertically relative to the fixed block 31. As the locking screw 332 descends, the pushing inclined surface 332a pushes the matching inclined surface 331c, pushing the locking block 331, thereby causing the locking block 331 to abut against the circumferential side of the adjusting screw 32. By rotating multiple locking screws 332, multiple locking blocks 331 abut against the side of the adjusting screw 32, thereby clamping the adjusting screw 32 and limiting its rotation.

[0062] In this embodiment, the air flotation platform is used to support the display panel during inkjet printing. The flatness of the display panel must be maintained during printing, ensuring the droplet landing accuracy during inkjet printing. This improves inkjet printing performance and enables high-resolution display panel printing.

[0063] By adjusting the air flotation modules 2 by coordinating the screws 32 and the fixing blocks 31, the air flotation platform, composed of multiple air flotation modules 2, can achieve a flatness of 5-10 microns on the outlet surface. This means the height difference between the highest and lowest points of the outlet surface is 5-10 microns. This ensures the flatness of the display panel when supporting it, enabling high-precision printing.

[0064] Due to the setting of the locking assembly 33, after the adjustment of the flotation module 2 is completed, the adjusting screw 32 is locked by the locking assembly 33, thereby limiting the rotation of the adjusting screw 32, preventing the adjusting screw 32 from rotating due to external factors such as vibration, ensuring that the flotation module 2 is in a stable position, and ensuring the flatness of the outlet surface of the flotation platform.

[0065] Furthermore, since the locking screw 332 is vertically inserted into the fixed block 31, it is convenient to extend the locking screw 332 into the installation gap a. By operating the locking screw 332 in the vertical direction, the adjusting screw 32 can be locked. This allows the adjusting screw 32 to be locked within the narrow installation gap a, providing an operational method for locking the adjusting screw 32. In addition, when locking the adjusting screw 32, it is achieved by clamping the adjusting screw 32. Therefore, when locking the adjusting screw 32, the adjusting screw 32 will not rotate, and thus the height of the flotation module 2 will not change. This makes it easier to ensure the flatness of the outlet surface of the flotation platform formed by splicing multiple flotation modules 2.

[0066] 3-5 , in this embodiment, the locking assembly 33 includes two locking blocks 331 and two locking screws 332 . The adjusting screw 32 can be firmly clamped by the two locking blocks 331 , and the fixing of the adjusting screw 32 can be completed by only operating the two locking screws 332 . The structure of the height adjustment mechanism 3 also facilitates the operation of locking the adjusting screw 32 .

[0067] 4-6 , preferably, a locking groove 331a is formed on the side of the locking block 331. The groove wall of the locking groove 331a mates with the side of the adjusting screw 32, and the locking groove 331a is tightly pressed against the side of the adjusting screw 32. Specifically, the locking groove 331a is arranged in an arc-shaped groove. When the locking block 331 is pressed against the adjusting screw 32, the provision of the locking groove 331a increases the contact area between the locking block 331 and the adjusting screw 32, thereby increasing the friction between the locking block 331 and the adjusting screw 32 and improving the locking stability of the adjusting screw 32.

[0068] Furthermore, a through-receiving slot is formed on the side of the fixing block 31, and the multiple locking blocks 331 are all located within the receiving slot. By providing the receiving slot, the locking blocks 331 are integrated into the fixing block 31, thereby improving the integration of the locking blocks 331 and the fixing block 31, reducing the size of the height adjustment mechanism 3, and facilitating the placement of the height adjustment mechanism 3 within the installation gap a.

[0069] 4-6 , a connecting strip 331 b is further provided at the bottom end of the locking block 331, and the locking block 331 is fixedly connected to the fixing block 31 via the connecting strip 331 b. As the locking screw 332 pushes the locking block 331, the connecting strip 331 b deforms to support the movement of the locking block 331 and tighten against the adjusting screw 32.

[0070] It should be noted that the gap between the locking block 331 and the adjusting screw 32 is small. Preferably, the gap between the locking block 331 and the adjusting screw 32 is 0.3-1 mm. Only a small deformation of the connecting strip 331b is required to achieve the locking block 331 being pressed against the adjusting screw 32.

[0071] In this embodiment, the locking block 331 and the fixing block 31 are integrally formed, and grooves are cut on the side of the block workpiece to form the locking block 331 and the fixing block 31 .

[0072] In other embodiments, the two locking blocks 331 are slidably arranged on the fixed block 31 through a guide rail and guide groove structure, and the locking screw 332 is used to push the locking block 331 to slide, so that the locking block 331 is pressed against the adjusting screw 32 to lock the adjusting screw 32.

[0073] 1-3 , the air flotation module 2 further includes a mounting plate 21 and a plurality of air flotation blocks 22. A height adjustment mechanism 3 is connected to the side of the mounting plate 21. The plurality of air flotation blocks 22 are evenly fixed to the mounting plate 21, with their air outlet surfaces coplanar.

[0074] Referring to Figures 1-3, in this embodiment, the mounting plate 21 is a square plate, with a plurality of air flotation blocks 22 mounted on its top surface. The air flotation blocks 22 are also square blocks. Three or four air flotation blocks 22 are mounted on each mounting plate 21, and the plurality of air flotation blocks 22 are spaced apart along the width of the air flotation blocks 22.

[0075] With this arrangement, since the flotation module 2 is further assembled from multiple flotation blocks 22, the flatness of the outlet surface of each individual flotation block 22 is easier to control. Furthermore, small-sized flotation blocks 22 are less likely to deform and affect the flatness of their outlet surfaces. Therefore, the outlet surface flatness of the flotation module 2 assembled from multiple flotation blocks 22 is more precise and less likely to change later. The outlet surface flatness of the flotation platform assembled from multiple flotation modules 2 is also higher, resulting in a smoother display panel when supported, improving the accuracy of inkjet printing on the display panel.

[0076] In this embodiment, the air flotation blocks 22 are secured to the mounting plate 21 via multiple bolts. Due to manufacturing tolerances, the heights of each air flotation block 22 may vary. When assembling the air flotation module 2, air flotation blocks 22 with a height difference of 0-5 microns are selected to ensure the flatness of the air outlet surface of the air flotation module 2.

[0077] This arrangement allows multiple flotation blocks 22 of varying heights to be assembled into flotation modules 2. This not only effectively utilizes the flotation blocks 22 but also improves the flatness of the outlet surfaces of the flotation modules 2. Even if each flotation module 2 subsequently has a different height, the height adjustment mechanism 3 can be used to align the outlet surfaces of the assembled flotation modules 2, ensuring the flatness of the outlet surface of the flotation platform.

[0078] In this embodiment, after multiple air flotation modules 2 are assembled into an air flotation platform, multiple air flotation blocks 22 are arranged along the length and width directions of the air flotation blocks 22. Therefore, the multiple air outlet holes of the air flotation platform are regularly and evenly distributed. When supporting the display panel, the force points of the display panel are more uniform, and the display panel can be fully covered, which makes the support for the display panel more stable, ensuring that the display panel is more flat when supported by the air flotation platform.

[0079] In addition, the multiple air flotation blocks 22 can be independently controlled, and the support flatness of the air flotation platform assembled from the multiple air flotation modules 2 can be adjusted by varying the air supply pressure, thereby improving the stability of the display panel support.

[0080] In this embodiment, mounting plate 21 comprises a marble slab. This arrangement prevents deformation of mounting plate 21 due to temperature fluctuations, and also ensures surface flatness. Once air flotation block 22 is assembled on mounting platform 1, deformation of mounting plate 21 is unlikely to affect the height and levelness of the air outlet surface of air flotation block 22. This ensures high-precision flatness of the air outlet surface of the air flotation platform over a long period of time.

[0081] Referring to Figures 1, 7, and 8, the spliced ​​air-floating platform for display panel processing further includes a shielding assembly 4, which includes a plurality of shielding strips 41. Some shielding strips 41 are fixed to the mounting platform 1, while others are fixed to the mounting platform 1 and the mounting plate 21. The shielding strips 41 are used to block gaps between adjacent air-floating blocks 22.

[0082] This arrangement allows the shielding strips 41 to block the gaps between the air flotation blocks 22. This prevents airflow from entering the gaps between the air flotation blocks 22 when supporting the display panel, reducing airflow turbulence and improving the stability of the display panel support. Furthermore, blocking the gaps between the air flotation blocks 22 prevents debris from entering the gaps, thus maintaining a clean air flotation platform.

[0083] Referring to Figures 1, 7, and 8, the shielding assembly 4 specifically includes a plurality of connecting rods 42 and a plurality of connecting blocks 43. The connecting rods 42 and connecting blocks 43 are positioned in the gaps between the air flotation blocks 22. Some connecting rods 42 are bolted to the mounting platform 1; others are bolted to the connecting blocks 43. The connecting blocks 43 are also bolted to the sides of the mounting plate 21. The shielding strip 41 is then bolted to the connecting rods 42, completing the installation of the shielding strip 41.

[0084] In this embodiment, when determining the spacing between the air floating blocks 22, the shielding strips 41 can be placed between adjacent air floating blocks 22, and the opposite side surfaces of the shielding strips 41 are respectively in contact with the two air floating blocks 22 to determine the gap width between the air floating blocks 22, thereby facilitating the determination of the installation position of the air floating blocks 22.

[0085] The present invention provides a spliced ​​air flotation platform for display panel processing. Because the platform is composed of multiple air flotation modules 2, each air flotation module 2 has a relatively small outlet surface, making it easier to control the flatness of the outlet surface during processing. Smaller air flotation modules 2 are also less likely to deform and affect the flatness of their outlet surfaces. Furthermore, the air flotation modules 2 can be adjusted in height via height adjustment mechanisms 3. When the air flotation modules 2 are mounted on a mounting platform 1, the outlet surfaces of the air flotation modules 2 can be adjusted to a horizontal position via the multiple height adjustment mechanisms 3. The height adjustment mechanisms 3 can also be used to align the outlet surfaces of multiple air flotation modules 2, thereby ensuring the flatness of the outlet surface of the spliced ​​air flotation platform. Even if the outlet surfaces of different air flotation modules 2 subsequently vary in height or angle, the height adjustment mechanisms 3 can still ensure that the outlet surfaces of the multiple air flotation modules 2 are aligned, ensuring the flatness of the display panel while on the platform and improving the processing quality of the display panel.

[0086] In addition, only an installation gap a is left between adjacent air flotation modules 2, and the support gap formed between adjacent air flotation modules 2 is small. The distribution density of the air flotation modules 2 is large, so the air outlet distribution density of the air flotation platform is large, and there is no large air-out area on the air flotation platform, so that the supporting force applied to the display panel is more uniform. When the display panel is on the air flotation platform, the force on each part of the display panel is uniform, and the flatness of the display panel is better, thereby improving the accuracy of the inkjet printing processing of the display panel and improving the printing quality of the display panel.

[0087] Due to the setting of the installation gap a between the flotation modules 2, it is convenient to accommodate the height adjustment mechanism 3. After multiple flotation modules 2 are installed on the mounting platform 1, the height of the fixing block 31 can still be adjusted by extending a tool into the installation gap a in the vertical direction to operate the adjustment screw 32, thereby supporting the adjustment of the flatness and height of the air outlet surface of the air flotation module 2, making it convenient to adjust multiple air flotation modules 2 to a state where the air outlet surfaces are in the same plane.
