Description

Technical Field

[0001] The utility model relates to the technical field of screen storage, in particular to a screen storage and shipping trolley. Background Art

[0002] In precision manufacturing fields such as printing, electronics, and semiconductors, screen cleanliness is directly related to product quality. Traditional handling exposes screens to airborne contamination from dust, particles, and harmful gases, compromising precision and lifespan. While manual dust control measures such as covering with dust sheets and regular cleaning are widely used, their effectiveness is limited and they can easily become new sources of contamination. Existing carts equipped with cleaning devices, such as negative pressure systems, can effectively improve screen cleanliness, but their relatively high cost increases operating costs. They are also limited in their ability to remove airborne dust, particles, and harmful gases, and cannot fully guarantee screen cleanliness during prolonged, frequent use. Sealed cart designs, while effectively shielding against external contaminants, can also make them difficult to maneuver and operate, limiting their potential applications. While some removable dust covers are convenient, improper operation or inadequate sealing can compromise their cleaning effectiveness.

[0003] Therefore, in order to correct the above-mentioned defect, we have proposed a screen storage and shipping trolley. Summary of the Invention

[0004] The technical problem solved by the utility model is to provide a screen storage and shipping trolley.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a screen storage and shipping trolley, comprising a trolley with a carriage installed on it, a purification system installed on the top of the carriage, baffles equidistantly provided on the inner top and bottom of the carriage, a screen being sandwiched between every two adjacent baffles, the purification system comprising a filter installed on the top of the carriage and communicating with the interior of the carriage, the top of the filter being connected to an AC-FFU.

[0006] Furthermore, a smooth strip is fixed between the two baffles.

[0007] Furthermore, the inlet end between the two baffles is in a flared shape.

[0008] Furthermore, the baffle is made of Teflon material.

[0009] Furthermore, the feed end of the carriage is open.

[0010] Compared with the existing technology, the beneficial effects of the present invention are: the present invention improves the cleanliness of the screen, reduces costs, enhances convenience and flexibility, and broadens the scope of application through the purification system composed of filters and AC-FFU, and combines physical isolation and air purification to provide an efficient, convenient and economical clean protection solution for the screen, and uses high-efficiency filters to ensure that the air cleanliness inside the cart reaches high standards. The device body and key components adopt a modular design, which is easy to disassemble, replace and maintain, reducing maintenance costs and improving equipment reliability. The design is simple and modular, which is easy to disassemble and repair; it reduces the maintenance cost and time of the device; the cart is easy to move and operate, and can adapt to different scenarios and needs.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The utility model provides a technical solution:

[0018] See also Figure 1-3 A screen storage and shipping trolley includes a trolley 1, on which is mounted a carriage 2 made of stainless steel to ensure safety during screen transportation. A purification system consisting of a filter 3 and an AC-FFU 4 is installed on the top of the carriage 2. The top uses a mature fan filter unit, namely FFU. FFU is a self-powered, modular terminal air supply device with filtering effect. The fan inhales air from the top of the FFU and filters it through HEPA. The filtered clean air is evenly delivered on the entire air outlet surface at a wind speed of 0.45m / s±20%, ensuring a clean and stable environment inside the trolley.

[0019] Secondly, the feeding end of the carriage 2 is open, that is, the carriage 2 is designed to be semi-closed, and the feeding port is not closed, which is convenient for transportation.

[0020] In addition, wear-resistant Teflon bars 6 are equidistantly provided on the inner top and bottom of the carriage 2. A screen is placed between every two adjacent bars 6, so that the screens are placed in order without interfering with each other. A smooth bar 5 is fixed between the two bars 6, that is, two symmetrical fluid bars 5 are in contact with the upper and lower ends of the screen respectively. The smooth bar 5 is used to generate rolling friction and reduce metal chips.

[0021] During loading, in order to facilitate the placement of the screen between the two baffles 6 , the inlet end between the two baffles 6 is expanded, that is, the inlet is enlarged.

[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
