[0033] This utility model provides a Class 100 cleanroom 100, which can be used to assemble display optical units and to package assembly requirements and effects.
[0034] Reference Figs. 1-2 The Class 100 cleanroom 100 provided in this embodiment includes a cleanroom body 10, a first FFU (Fan Filter Unit) 20, a return air duct 40, and an operating table 60. The cleanroom body 10 has a working area 11 with an opening. The first FFU 20 is located in the cleanroom body 10, and the air outlet of the first FFU 20 is located in the working area 11. The air outlet of the return air duct 40 is connected to the air inlet of the first FFU 20, and the air inlet of the return air duct 40 is located at the opening of the working area 11. The operating table 60 is located in the working area 11 and is used to provide an operating surface for the operator.
[0035] Specifically, the cleanroom body 10 is generally a three-dimensional structure and forms at least one work area 11. One side of the work area 11 has an opening that allows the operator's hand to enter the work area 11 to perform assembly operations. Apart from the opening, the other sides of the work area 11 are relatively sealed.
[0036] The first FFU 20 is installed on the cleanroom, and its outlet is approximately located on the side of the cleanroom body 10 opposite to the opening of the work area 11, allowing air to be blown towards the opening. The inlet of the return air duct 40 is located at the opening of the work area 11, and its outlet is connected to the inlet of the first FFU 20. When the first FFU 20 is working, return air pressure is generated at the inlet of the return air duct 40, drawing air from the work area 11 into the first FFU 20. After being purified by the first FFU 20, the air is blown into the work area 11 from the outlet, and then returns to the first FFU 20 for purification through the inlet, thus forming a self-purification cycle.
[0037] The control panel 60 is located in the work area 11, and allows the operator to extend their hands into the work area 11 through the opening of the work area 11 and perform operations on the control panel 60.
[0038] The above-mentioned technical solution of this utility model sets up a cleanroom main body 10, an operating table 60 located inside the cleanroom, and a first FFU 20 that forms a self-purifying cycle with the cleanroom main body 10 through a return air duct 40. When the operator needs to perform work, the first FFU 20 can be activated, and return air pressure is generated at the air inlet of the return air duct 40 to draw air from the work area 11 into the first FFU 20. After being purified by the first FFU 20, the air is blown into the work area 11 from the air outlet, and then returns to the first FFU 20 for purification through the air inlet. This forms a self-purifying cycle, thereby achieving self-purification of the air in the work area 11, realizing a Class 100 cleanroom working environment, which meets the requirements of display optical unit assembly operations. Furthermore, the Class 100 cleanroom 100 in this embodiment has a simple structure and relatively small size, resulting in low construction and maintenance costs. At the same time, the Class 100 cleanroom 100 in this embodiment can reduce the difficulty of production management and help improve assembly quality.
[0039] In one specific embodiment of this utility model, an operating room 12 is formed inside the main body 10 of the cleanroom. The operating room 12 is connected to the work area 11 through an opening and is used to provide movement space for the operators.
[0040] Specifically, the operating room 12 is located on the side of the work area 11 with an opening, and the two are connected by the opening, thus forming a movement space that allows operators to sit, stand, and walk within it. Operators can then sit in the operating room 12 to perform assembly work. Simultaneously, the cleanroom main body 10 has an openable and closable door or curtain corresponding to the operating room 12. This allows operators to enter the operating room 12 while also isolating it from the outside environment, thereby reducing the impact of the external environment on the cleanroom main body 10 and improving the cleanliness within the cleanroom main body 10.
[0041] In one specific embodiment of this utility model, a second FFU 30 is also included. The second FFU 30 is disposed at the top of the operating room 12 and is adapted to supply clean air to the operating room 12. Specifically, the air inlet of the second FFU 30 is located outside the cleanroom main body 10, while the air outlet is located inside the operating room 12, and is adapted to blow air downwards from the top of the operating room 12. This not only replenishes the operating room 12 with fresh air, but also prevents operators from carrying away foreign objects during movement, thereby reducing the impact on the environment of the work area 11.
[0042] In one specific embodiment of this utility model, it further includes two return air slots 50, both of which are connected to the air inlet. One return air slot 50 is disposed at the top of the opening, and the other return air slot 50 is disposed at the bottom of the opening, with the inlets of the two return air slots 50 being arranged opposite each other.
[0043] Specifically, the return air duct 50 is strip-shaped and is located on the upper and lower sides of the opening with the inlets facing each other. Correspondingly, there are two return air ducts 40, which are located on the upper and lower sides of the work area 11, and the inlets of the two return air ducts 40 are respectively connected to the outlets of the two return air ducts 50.
[0044] Optionally, the return air duct 50 can be installed in the work area 11. In this embodiment, the return air duct 50 is installed in the control room 12.
[0045] This embodiment sets up two return air ducts 50, which on the one hand can expand the area of the return air inlet, thereby guiding the return air direction and increasing the coverage area of the clean air blown out by the first FFU 20 in the work area 11, reducing the dust collection dead corners in the work area 11, and thus improving the cleanliness of the work area 11. On the other hand, setting the return air ducts 50 at the opening and setting them opposite each other can also timely suck away foreign objects that are formed and floated in the operating room due to personnel activities from both the top and bottom, preventing foreign objects from entering the work area 11 through the opening, thereby further improving the cleanliness of the work area 11.
[0046] In one specific embodiment of the present invention, at least three sides of the operating table 60 are connected to at least three side walls of the work area 11, and at least one side of the operating table 60 is arranged facing the operating room 12.
[0047] Specifically, the operating table 60 is rectangular and can accommodate 1-2 people, preferably accommodating only one person. The working area 11 is a rectangle with a cross-section approximately the same as the operating table 60, and its sides are arranged around the three adjacent sides of the operating table 60. Correspondingly, the bottom of the working area 11 is located below the operating table 60, and the working area 11 is positioned above the operating table 60. Thus, the working area 11 is a cuboid box-shaped structure with an opening on one side. The three adjacent sides of the operating table 60 are connected and fixed to the side wall of the working area 11, and the other side of the operating table 60 corresponds to the opening of the operating table 60.
[0048] Of course, the operating table 60 can also be formed into other shapes, such as triangles, trapezoids, pentagons, and other polymorphs, which can be adjusted according to operational needs. Correspondingly, the work area 11 can be adjusted according to the shape of the operating table 60.
[0049] In one specific embodiment of this utility model, the operating table 60 includes a perforated metal plate and a base plate located below the perforated metal plate, and a dust collection chamber is formed between the base plate and the perforated metal plate.
[0050] Specifically, the perforated metal plate can be made of perforated stainless steel, perforated aluminum, or perforated aluminum alloy, etc. The height of the perforated metal plate from the ground is approximately 600-1000mm, which can be set according to needs. The base plate is located below the perforated metal plate, and the distance between the base plate and the perforated metal plate is approximately 10-200mm. A dust collection chamber is formed between the base plate and the perforated metal plate. This ensures that foreign objects generated by friction in the work area 11 and carried by operators fall into the dust collection chamber due to gravity or wind. At the same time, the sealed integrated chamber reduces the flow of gas into the work area 11, thereby effectively reducing the entry of foreign objects into the dust collection chamber and not affecting normal clean operations.
[0051] Furthermore, the base plate can be a separately installed board or a board that forms the bottom surface of the work area. The bottom surface of the work area 11 is set close to the operating table 60 and away from the ground. In this way, the bottom of the work area 11 forms a pressure relief vent, thereby reducing the impact of the air pressure inside the cleanroom body 10 caused by the blowing of the first FFU 20 and the second FFU 30, and thus providing a relatively comfortable environment for the operators.
[0052] In one specific embodiment of this utility model, both the first FFU 20 and the second FFU 30 include a connected air supply fan 31 and an air filter 32. The air inlet of the air filter 32 of the first FFU 20 is connected to the air outlet of the return air duct 40, and the air inlet of the air filter 32 of the second FFU 30 is connected to the external environment of the cleanroom body 10. Thus, the air supply fan 31 can be used to drive air circulation, and the air filter 32 is used to purify the flowing air, thereby achieving the air purification requirements.
[0053] In one specific embodiment of this utility model, the cleanroom main body 10 includes profiles 13 and plates 14, with the plates 14 embedded in the frame structure formed by the profiles 13. Specifically, the plates 14 are connected to the frame structure by adhesive, screwing, or snap-fit, and the joints can be sealed by filling with sealant. This embodiment uses a combination of profiles 13 and plates 14 to form the cleanroom main body 10, which improves the structural strength of the cleanroom main body 10 while reducing the construction and maintenance costs of the cleanroom main body 10.
[0054] In one specific embodiment of this utility model, the profile 13 is a stainless steel profile 13, an aluminum profile 13, or an aluminum alloy profile. The sheet 14 is an acrylic sheet, glass, or an anti-static mesh.
[0055] The base plate of the operating table 60 can be made of acrylic sheet, glass, or anti-static mesh, meaning the base plate of the operating table 60 can be made of the same material as the main body 10 of the cleanroom. Of course, in other embodiments, the base plate of the operating table 60 can be made of a different material than the main body 10 of the cleanroom.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
