Description

Technical Field

[0001] This invention relates to the field of inspection room technology, specifically to an OLED glass production inspection room. Background Technology

[0002] In the production and processing of OLED (Organic Light Emitting Diode) glass, the inspection process is a core link in ensuring product yield and final display performance. After undergoing multiple precision processes such as coating, photolithography, and etching, the glass substrate may develop defects such as tiny cracks, particle contamination, scratches, or uneven film layers. If these defects are not accurately identified in the early stages, they will directly lead to the waste of materials in subsequent module segments and may even affect the lifespan and image quality consistency of the finished display panel. Therefore, in the quality control system of OLED glass manufacturing, efficient defect detection plays the role of a "gatekeeper."

[0003] However, high-precision optical inspection equipment is extremely sensitive to the external environment, especially airborne dust particles. When particles land on the glass surface or float in the inspection optical path, they are easily misidentified by the inspection system as defects in the glass itself, resulting in a large number of false positive reports and seriously interfering with normal quality judgment. Conversely, real defects may also be obscured by dust, causing missed detections. To solve this problem, the industry generally sets up independent "inspection rooms" within the larger workshop environment. The core function of this small environment is to isolate the airflow from the external workshop and provide a continuous and stable laminar flow of clean air through active filtration, ensuring that the inspection equipment operates in a local clean area of, for example, ISO 5 level or even better.

[0004] Currently, common small-scale testing rooms typically use modular aluminum profiles to construct the main frame, offering advantages such as light weight and easy assembly. The top area houses fan filter units (FFUs) and matching pre-filters / high-efficiency filters, while the sides utilize transparent plastic curtains for flexible enclosure. This facilitates observation and material handling by operators and maintains positive pressure to some extent, preventing the intrusion of dirty air from the outside. However, in long-term actual operation, this traditional structure has gradually revealed key defects. First, due to cost control or insufficient initial design experience, the FFUs are often sparsely arranged, resulting in gaps in air supply or an overall air exchange rate that fails to meet the requirements of high cleanliness levels. Insufficient airflow coverage prevents the airflow from forming an effective unidirectional vertical laminar flow. Clean airflow becomes turbulent due to interference from indoor heat sources and obstacles before reaching the equipment height, reducing the actual particle flushing and replacement efficiency. Long-term monitoring shows that the dust particle concentration inside the testing room remains high, even failing to consistently reach the designed cleanliness level. Second, in pursuit of overall compactness or to reduce the occupation of beams and columns above, the reserved maintenance space at the top is severely insufficient. When it's necessary to replace the motor, impeller, or HEPA filter inside the FFU (Fan Filter Unit), maintenance personnel often have difficulty entering or can only work in a prone position. This not only makes the maintenance process extremely cumbersome, time-consuming, and labor-intensive, but also increases safety risks. Sometimes, to complete a single maintenance, it is even necessary to suspend the entire inspection line, significantly impacting continuous production.

[0005] To address this, we have developed a new type of OLED glass production and inspection room. Summary of the Invention

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an OLED glass production inspection room that solves the problems of poor filtration and high dust particle levels found in existing devices during use.

[0007] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: an OLED glass production inspection room, including two side supports, a supporting steel frame is fixedly connected between the two side supports, and a plurality of first assembly slots extending to the bottom are evenly opened on the top of the supporting steel frame, and blind plates are fixedly connected to the inner surfaces of the plurality of first assembly slots. The top of the supporting steel frame is evenly provided with several second assembly slots that extend to the bottom, and filters are fixedly connected to the inner surfaces of the several second assembly slots. Each of the filters is provided with an FFU directly above it, and the FFU is fixedly connected to the top of the supporting steel frame.

[0008] Preferably, the distance between the top of the supporting steel frame and the top of the two side supports is 450-550mm.

[0009] Through the above technical solution, this spacing range can ensure that the air outlet of the FFU is kept close to the production equipment below, so that the filtered clean air can quickly reach the surface of the equipment and reduce the re-attachment of dust along the way. It can also provide maintenance personnel with sufficient operating space to facilitate maintenance of the FFU from the top of the supporting steel frame.

[0010] Preferably, a number of the first assembly slots are arranged in two rows, and a number of the second assembly slots are also arranged in two rows, with the two rows of second assembly slots located between the two rows of first assembly slots.

[0011] With the above technical solution, the two rows of second assembly slots are centrally arranged in the middle of the supporting steel frame. The filters fixed inside them and the FFU form a central centralized air supply area, while the blind plates fixed in the two rows of first assembly slots on both sides achieve reliable sealing, so that clean air accurately covers the core area of ​​the bottom equipment.

[0012] Preferably, the spacing between two adjacent FFUs is 30-50 mm.

[0013] Through the above technical solution, the compact spacing allows multiple FFUs to form a dense matrix on the top of the supporting steel frame, with no large gaps in the air supply coverage. This avoids insufficient airflow or filtration dead zones caused by sparse FFU arrangement, significantly enhances the circulating filtration intensity per unit area, and thus more effectively reduces the concentration of dust particles in the testing room.

[0014] Preferably, the two side supports are fixed to the supporting steel frame by welding.

[0015] The above technical solution eliminates the risk of gaps and loosening through welding, making the overall structure more stable and reliable.

[0016] Preferably, both side supports and the supporting steel frame are made of steel.

[0017] Through the above technical solutions, steel materials ensure sufficient structural strength and rigidity, and are not easily deformed during long-term use.

[0018] Preferably, several of the first and second assembly slots are square slots.

[0019] The above technical solution makes the square channel easy to process and position, matches well with the rectangular shape of the blind plate and filter, and makes installation more convenient.

[0020] Preferably, all of the aforementioned blind plates are made of steel plates.

[0021] Through the above technical solutions, blind flanges made of steel plates have good rigidity and high flatness.

[0022] Preferably, the four outer walls of the plurality of blind plates are respectively sealed and fixed to the four inner walls of the adjacent first assembly groove.

[0023] The above technical solution eliminates the air leakage gaps around the blind plate by sealing and fixing on all four sides, further improving the airtightness.

[0024] Preferably, all of the FFUs are fixedly connected to the top of the supporting steel frame.

[0025] The above technical solution simplifies the assembly structure by directly fixing the connection and ensures accurate alignment between the FFU and the filter below.

[0026] (III) Beneficial Effects This invention provides an OLED glass production inspection room. It has the following beneficial effects: This OLED glass production and inspection room forms a vertically aligned air supply channel by fixing blind plates in the first assembly slot, filters in the second assembly slot, and FFUs directly above the top of the supporting steel frame. At the same time, the blind plates enclose the non-air supply area, effectively avoiding leakage of unfiltered air and cross-contamination of clean airflow. Compared with the problems of sparse FFU arrangement and poor filtration effect in the background technology, it significantly reduces the concentration of dust particles in the inspection room and improves the cleanliness of the environment.

[0027] This OLED glass production and inspection room simplifies the top structure by directly fixing the FFUs to the top of the supporting steel frame and ensuring that each FFU corresponds one-to-one with the filter below, eliminating the need for an additional intermediate supporting frame. At the same time, since the FFUs are located above the supporting steel frame, it provides maintenance personnel with space to operate directly from the top, solving the shortcomings of the original technology where insufficient top reserved space led to cumbersome FFU maintenance and difficult operation, thus improving the convenience and safety of maintenance.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides an OLED glass production inspection room, including two side supports 1, and a supporting steel frame 4 is fixedly connected between the two side supports 1. The distance between the top of the supporting steel frame 4 and the top of the two side supports 1 is 450-550mm. The supporting steel frame 4 is a grid-shaped rigid frame welded from rectangular steel pipes. It is horizontally arranged between the two side supports 1 and fixedly connected to the side supports 1 by welding to form an integral frame.

[0032] The top of the supporting steel frame 4 is evenly provided with several first assembly slots 5 extending to the bottom. The inner surfaces of the first assembly slots 5 are all fixedly connected with blind plates 3. The blind plates 3 are made of stainless steel or galvanized steel plates with a thickness of 1.5-3mm and their shape matches the first assembly slots 5. The edges of the blind plates 3 are fixedly connected to the inner surfaces of the first assembly slots 5 by sealant, rivets or screws, and sealing gaskets are provided at the connection. The top of the supporting steel frame 4 is evenly provided with several second assembly slots 7 extending to the bottom. The inner surfaces of the second assembly slots 7 are all fixedly connected with filters 6. The first assembly slots 5 are arranged in two rows, and the second assembly slots 7 are also arranged in two rows, with the two rows of second assembly slots 7 located between the two rows of first assembly slots 5. The outer edge of the filter 6 is tightly fitted to the inner surface of the second assembly slot 7 by sealing strips or sealant and fixed by clamping parts or screws. The first assembly slots 5 and the second assembly slots 7 are all square slots.

[0033] Several filters 6 are equipped with FFU2 directly above them, and FFU2 is fixedly connected to the top of the supporting steel frame 4. The distance between two adjacent FFU2 is 30-50mm. FFU2 is a fan filter unit, which integrates a centrifugal fan, a pre-filter and control circuit. The outer shell is made of aluminum zinc plate or stainless steel plate. The lower air outlet of each FFU2 is directly opposite and tightly connected to the upper air inlet of the corresponding filter 6. FFU2 is directly fixed to the top surface of the supporting steel frame 4 by screws or clips, and a sealing gasket is provided between its bottom and the supporting steel frame 4.

[0034] Working principle: When all FFU2s are turned on, the fans inside the FFU2s start running, drawing in air from above the testing room and blowing it downwards. The air first passes through the primary filtration unit of the FFU2, removing most of the suspended particles.

[0035] The air then continues to flow downwards, directly into the filter 6, which is fixedly connected to the supporting steel frame 4. The filter 6 performs high-efficiency secondary filtration of the air, further intercepting micron-sized dust particles. The clean air, after double filtration, flows evenly from the bottom of the filter 6, covering the entire interior space of the inspection room, especially the glass production equipment area directly below, thus creating a localized clean environment.

[0036] In the remaining area supporting the steel frame 4, a blind flange 3 is fixed in the first assembly slot 5. The blind flange 3 completely seals the slots where the filter 6 is not installed, preventing untreated air from leaking directly downwards from these locations, and also preventing filtered clean air from mixing with dirty air, ensuring orderly airflow and good sealing.

[0037] Because the distance between the top of the supporting steel frame 4 and the top of the two side supports 1 is 500mm, meaning the entire top is lowered by 500mm, the distance between the air outlet of FFU2 and the production equipment below is significantly shortened. The filtered air reaches the equipment surface via a shorter path, reducing its travel in open spaces and effectively reducing the risk of airborne dust particles being re-entrained.

[0038] Multiple FFU2 units are spaced 30-50mm apart, and their arrangement has been centrally adjusted to completely cover the bottom equipment area. This dense layout enhances the airflow and circulation frequency per unit area, improving overall filtration efficiency. Simultaneously, with the supporting steel frame 4 lowered, ample operating space is created between its top and the inspection room ceiling. Workers can stand on top of the supporting steel frame 4 to perform routine inspections, maintenance, or replacements of the FFU2s without having to crawl, ensuring both convenience and safety during maintenance.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
