Description

Technical Field

[0001] The present application relates to the technical field of vacuum drying, and particularly relates to a thimble module, a support assembly and a vacuum drying system. Background Art

[0002] In the existing manufacturing processes of OLED devices or QLED devices, an inkjet printing process has been adopted. Among them, some functional materials can be processed by inkjet printing. For example, functional materials such as a hole injection layer (HIL), a hole transport layer (HTL), and an emissive layer material (EML) can be processed by inkjet printing, and other functional layers that can be inkjet printed are equally applicable. That is, for the existing pixel pits, the functional layer material ink is injected into the pixel pits by inkjet printing.

[0003] Regarding various influencing factors of the efficiency of OLED devices, the film forming uniformity of each functional layer material is a very important consideration. Generally, a vacuum drying device is used to dry and form a film on a substrate.

[0004] In related technologies, in some vacuum drying devices, a combination of a thimble assembly and a carrier plate is adopted. The thimble assembly includes a thimble plate and a plurality of thimbles. The plurality of thimbles are fixed on the thimble plate. The thimbles pass through the carrier plate, and the carrier plate or the thimble plate can be lifted and lowered. The substrate is supported at multiple points by the plurality of thimbles, so that the substrate is suspended above the carrier plate, and it is convenient to lift the substrate from below. When the substrate is dried, the carrier plate rises relative to the thimbles, and the carrier plate is used to support the substrate. In some vacuum drying devices, a plurality of thimbles are directly used to support the substrate at multiple points to facilitate lifting the substrate from below the substrate.

[0005] However, when using the combination of the thimble assembly and the carrier plate to support the substrate, since the number of thimbles is large and all need to pass through the carrier plate, there is an easy deviation between the positions of the thimbles and the positions of the openings on the carrier plate, and some thimbles cannot pass through the carrier plate. In addition, when only a plurality of thimbles are used to support the substrate, the thimbles are likely to support the printing area on the substrate, which is likely to cause a mura phenomenon and have an adverse effect on the film forming quality of the substrate surface. Summary of the Utility Model

Specific embodiments

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0039] The embodiment of the present application provides an ejector pin module, a support assembly, and a vacuum drying system. The needle body in the ejector pin module can slide freely relative to the base on the support surface along with the adjusting seat and is fixed on the base under the action of magnetic force. Thus, the position of the needle body can be conveniently adjusted, facilitating the synchronous penetration of multiple needle bodies through the carrier plate. Also, by adjusting the position of the needle body, the printing area of the substrate can be avoided to support the substrate, ensuring the film-forming quality of the substrate. The present application solves the technical problems in the related art that there are deviations between the positions of some ejector pins and the openings of the carrier plate, making it difficult to penetrate the carrier plate, and that some ejector pins are prone to supporting the printing area of the substrate, which is likely to have an adverse impact on the film-forming quality of the substrate surface.

[0040] Refer to Figure 1 and Figure 2, a thimble module, comprising a base 1, an adjusting seat 2 and a needle body 3. The needle body 3 is connected to the adjusting seat 2, and the adjusting seat 2 is slidably disposed on the base 1 and magnetically connected to the base 1, so as to realize the arbitrary adjustment of the position of the needle body 3 relative to the base 1, and under the action of magnetic force, the adjusting seat 2 and the needle body 3 are arbitrarily fixed at any position on the base 1.

[0041] Among them, the base 1 is used to be installed on an external plate body or a frame body, and the bases 1 of multiple thimble modules can be pre-installed on the external plate body or the frame body to provide an installation position for the adjusting seat 2 and the needle body 3.

[0042] Refer to Figures 1-3 , the base 1 includes a supporting surface 1a. In this embodiment, the supporting surface 1a is the top surface of the base 1. The adjusting seat 2 is placed on the supporting surface 1a, and the adjusting seat 2 is slidably disposed on the supporting surface 1a, and the adjusting seat 2 can slide to any position on the supporting surface 1a. The adjusting seat 2 is magnetically connected to the base 1, and under the action of magnetic force, the adjusting seat 2 is fixed at any position on the supporting surface 1a.

[0043] Refer to Figures 1-3 , the needle body 3 is rod-shaped, and the needle body 3 is installed on the adjusting seat 2, that is, the needle body 3 can slide arbitrarily on the supporting surface 1a along with the adjusting seat 2, and can be fixed at any position on the supporting surface 1a. In this embodiment, the needle body 3 is arranged perpendicular to the supporting surface 1a, and the needle body 3 is used to support the substrate.

[0044] With such a setting, when it is necessary to pass multiple needle bodies 3 on the thimble plate through the carrier plate, the positions of the corresponding needle bodies 3 can be adjusted, and the moving direction of the needle bodies 3 is not restricted, ensuring that all the needle bodies 3 can be respectively aligned with multiple through holes on the carrier plate one by one, so as to facilitate all the needle bodies 3 to accurately pass through the carrier plate. In addition, since the positions of the needle bodies 3 can be arbitrarily moved on the horizontal plane and fixed at any position, when supporting the substrate by multiple needle bodies 3 at multiple points, due to the flexibility of the positions of the needle bodies 3, the printing area of the substrate can be avoided for support, and the support of substrates with various different printing area distributions can be adapted, ensuring that the needle bodies 3 can avoid the printing area, reducing the possibility of mura, and ensuring the film forming quality on the substrate.

[0045] Refer to Figures 1-3 , specifically, an installation hole 2a is formed on the top surface of the adjusting seat 2, and the needle body 3 passes through the installation hole 2a. A locking hole 2b communicating with the installation hole 2a is formed on the side surface of the adjusting seat 2. The thimble module further includes a locking member 4, the locking member 4 is threadedly disposed through the locking hole 2b, and the locking member 4 abuts against the circumferential side surface of the needle body 3. By tightening the locking member 4, the needle body 3 can be fixed by using the locking member 4 to abut against the needle body 3. In this embodiment, the locking member 4 includes a locking bolt.

[0046] The needle body 3 is inserted into the adjustment seat 2 and fixed by the locking member 4. When the needle body 3 is damaged, the needle body 3 can be quickly replaced. In addition, when the needle body 3 is not needed at some positions, the needle body 3 can be pulled out from the adjustment seat 2.

[0047] Reference Figures 1-3 Further, the needle body 3 includes a fixed section 31 and a movable section 32. The fixed section 31 is inserted into the adjustment seat 2, and the movable section 32 is threadedly connected to the top of the fixed section 31. The movable section 32 is rotated relative to the fixed section 31 to change the height of the top of the movable section 32 relative to the fixed section 31.

[0048] With this arrangement, by adjusting the height of the top of the movable section 32, the height of the top of the needle body 3 of multiple ejector pin modules can be adjusted to be consistent. When multiple ejector pin modules synchronously support the substrate, the support heights of various parts of the substrate are ensured to be consistent, so as to evenly support the substrate, reduce the occurrence of mura, and ensure the film quality.

[0049] Part or all of the structure of at least one of the base 1 and the adjustment base 2 includes magnetic material, so that the adjustment base 2 is magnetically connected to the support surface 1 a of the base 1 .

[0050] Reference Figures 1-3 In this embodiment, the base 1 includes a magnetic block, that is, the base 1 is made of a magnetic material. In this embodiment, the adjustment seat 2 is partially or entirely made of a ferromagnetic material. Preferably, the entire adjustment seat 2 is made of a ferromagnetic material, specifically, stainless steel.

[0051] With this arrangement, after the base 1 is mounted on the external plate or frame, part of the plate or frame becomes magnetic, which facilitates determining the position where the adjustment seat 2 can be installed, so as to facilitate preliminary positioning of the needle body 3 .

[0052] Reference Figure 4 In some embodiments, the base 1 includes a base body 11 and a magnetic sheet 12, and the magnetic sheet 12 and the base body 11 are stacked and fixed. The magnetic sheet 12 and the base body 11 are fixed by bolts or adhesives. The adjustment seat 2 is magnetically connected to the support surface 1a through the magnetic sheet 12. The adjustment seat 2 is partially or entirely made of ferromagnetic material. Preferably, the entire adjustment seat 2 is made of ferromagnetic material, specifically, it can include stainless steel.

[0053] In this way, by integrating the magnetic sheet 12 on the seat body 11 and giving the seat body 11 magnetism, the magnetic connection between the base 1 and the adjustment seat 2 can be achieved.

[0054] Reference Figure 3, in some embodiments, the adjusting base 2 includes a magnetic base, that is, the adjusting base 2 is made of a magnetic material. In this embodiment, part or all of the base 1 is made of a ferromagnetic material. Preferably, the entire base 1 is a ferromagnetic material. Specifically, it may include stainless steel.

[0055] With such a setting, since the adjusting base 2 is made of a magnetic material, the adjusting base 2 can be flexibly fixed to the external frame, thereby improving the flexibility of the position of the needle body 3.

[0056] Furthermore, the needle body 3 is made of a ferromagnetic material, and the needle body 3 can be magnetically connected to the adjusting base 2, which facilitates the installation and removal of the needle body 3.

[0057] Refer to Figure 5 , in some embodiments, the adjusting base 2 includes a mounting base 21 and a magnetic plate 22. The magnetic plate 22 is mounted on the mounting base 21, and the mounting base 21 is magnetically connected to the supporting surface 1a through the magnetic plate 22. In this embodiment, the magnetic plate 22 is fixed to the bottom surface of the mounting base 21, and the mounting base 21 is connected to the needle body 3. The magnetic plate 22 contacts the supporting surface 1a. In this embodiment, part or all of the base 1 is made of a ferromagnetic material. Preferably, the entire base 1 is a ferromagnetic material. Specifically, it may include stainless steel.

[0058] Specifically, the magnetic plate 22 and the mounting base 21 are fixedly connected by bolts or adhesives.

[0059] With such a setting, by adding a magnetic plate 22 to the mounting base 21, the adjusting base 2 is given magnetism, and the magnetic connection between the adjusting base 2 and the base 1 can be realized.

[0060] Refer to Figure 3 and Figure 6 , in some embodiments, part or all of the adjusting base 2 and the base 1 have magnetism. That is, the adjusting base 2 includes a magnetic base, or the adjusting base 2 includes a mounting base 21 and a magnetic plate 22; the base 1 includes a magnetic block, or the base 1 includes a base body 11 and a magnetic sheet 12.

[0061] With such a setting, since both the adjusting base 2 and the base 1 have magnetism, the magnetic connection between the adjusting base 2 and the base 1 is more firm, and the adjusting base 2 is not likely to slide randomly relative to the base 1, ensuring that the position of the needle body 3 does not change.

[0062] An embodiment of the present application provides a thimble module. Since the adjusting seat 2 is magnetically connected to the supporting surface 1a of the base 1, the adjusting seat 2 and the needle body 3 can be fixed together at various positions on the supporting surface 1a of the base 1 at will, and the positions of the adjusting seat 2 and the needle body 3 can be moved relative to the base 1, and the positions of the adjusting seat 2 and the needle body 3 relative to the base 1 can be fixed under the action of magnetic force, so as to realize the position adjustment and fixation of the adjusting seat 2 and the needle body 3. Therefore, when multiple needle bodies 3 on the thimble plate all pass through the bearing plate, the positions of the corresponding needle bodies 3 can be adjusted, and the moving directions of the needle bodies 3 are not restricted, ensuring that all the needle bodies 3 can be respectively aligned with multiple through holes on the bearing plate one by one, so that it is convenient for all the needle bodies 3 to accurately pass through the bearing plate.

[0063] In addition, since the position of the needle body 3 can be moved freely on the horizontal plane and can be fixed at any position, when the substrate is supported by multiple needle bodies 3 at multiple points, due to the flexibility of the position of the needle body 3, the printing area of the substrate can be avoided for support, and the support of substrates with various different printing area distributions can be adapted, ensuring that the needle body 3 can avoid the printing area, reducing the possibility of mura, and ensuring the film forming quality on the substrate.

[0064] Another embodiment of the present application provides a support assembly, including the thimble module as described above.

[0065] Referring to Figure 7 , the support assembly further includes a support plate 5, and multiple thimble modules A are all installed on the support plate 5. Specifically, according to the shape of the substrate and the position of the printing area on the substrate, multiple thimble modules A are arranged at positions on the support plate 5 that avoid the printing area. When the multiple thimble modules A support the substrate, the printing area is avoided to support the substrate.

[0066] Another embodiment of the present application provides a support assembly. Since the support assembly includes the above-mentioned thimble module, the beneficial effects of the support assembly are the same as those of the above-mentioned thimble module, and will not be repeated here.

[0067] Another embodiment of the present application provides a vacuum drying system, including the thimble module as described above, and / or, the support assembly as described above.
