[0002] This application claims priority to Korean Patent Application No. 10-2023-0160512, filed November 20, 2023, and Korean Patent Application No. 10-2023-0176642, filed December 7, 2023, the entire disclosures of which are incorporated herein by reference.

[0003] The present invention relates to a chamber for storing equipment.

[0004] Recently, with the increasing demand for alternative energy sources, numerous technologies related to solar power generation are being developed. Among the solar panel manufacturing processes used in solar power generation, the process of manufacturing solar cells is a crucial one.

[0005] Solar cells are produced by processing materials like polysilicon into ingots, which are then cut and processed. The resulting cells are then loaded into cassettes for transport to the next manufacturing process.

[0006] The processed cells are loaded into cassettes and undergo various manufacturing processes. Specifically, the processed cells undergo cleaning and drying processes before being introduced into the deposition process. If the cut and processed cells come into contact with moisture in the atmosphere, oxidation can occur. This oxidation can reduce the efficiency of solar power generation.

[0007] Therefore, measures are needed to prevent oxidation on the surface of solar cells until the deposition of various materials on the surface is complete. To achieve this, one option is to create a chamber surrounding the entire perimeter of the equipment that transports the solar cells and fill it with a gas such as nitrogen.

[0008] At this time, these chambers can be very large. Therefore, there is a need to develop chambers that are easy to disassemble and assemble for convenient transport while also preventing gas leakage.

[0009] The object of the present invention is to provide a chamber for storing equipment that is easy to disassemble and assemble while preventing leakage of internal gas.

[0010] In one example, a chamber for storing equipment includes a profile portion including a first profile extending in a left-right direction, a second profile extending in a front-back direction, and a third profile extending in a vertical direction, a connecting portion connected to each end of the first profile, the second profile, and the third profile, a cover portion coupled to the profile portion and covering the profile portion, and a gasket portion disposed between the end of the profile portion and the connecting portion, wherein the gasket portion may have a surface with unevenness.

[0011] In another example, the first profile may be formed to have different lengths in the vertical direction and front-back direction, the second profile may be formed to have different lengths in the vertical direction and left-right direction, and the third profile may be formed to have different lengths in the left-right direction and front-back direction.

[0012] In another example, the front-back length of the first profile may correspond to the left-right length of the second profile, the up-down length of the second profile may correspond to the front-back length of the third profile, and the left-right length of the third profile may correspond to the up-down length of the first profile.

[0013] In another example, the connecting portion may include a connecting portion body and an insertion member penetrating the connecting portion body and the gasket portion and inserted into an end of any one of the first to third profiles.

[0015] In another example, the insertion member includes a catch area disposed inside the connecting body and a protruding area protruding from the catch area toward the profile portion and penetrating through a through hole of the connecting body, wherein the catch area may have a diameter larger than the protruding area.

[0016] In another example, a through hole having a diameter corresponding to the diameter of the engaging area may be formed on a surface facing the surface of the connecting body where the through hole is formed, and the through hole may be formed at a position facing the through hole.

[0017] In another example, when the wall of the connecting body facing the first profile is referred to as the first wall, the connecting part may further include a first fitting projection protruding from the upper and lower ends of the first wall toward the first profile, and the gasket portion may include a first gasket fitted between the first wall and the first profile, and the first gasket may include a first fitting groove that is recessed at a position corresponding to the first fitting projection among the first gasket body and the first gasket body, and in which the first fitting projection is disposed inside.

[0018] In another example, second left and right insertion grooves extending in the front-back direction are formed on the left and right walls of the second profile, third left and right insertion grooves extending in the up-down direction are formed on the left and right walls of the third profile, and when a wall facing the first wall of the connecting body is referred to as a second wall, an L-shaped first groove may be formed on the second wall that is connected to the second left and right insertion groove and the third left and right insertion groove.

[0019] In another example, the equipment storage chamber may further include a first sealing member inserted into the second left and right insertion grooves, the third left and right insertion grooves, and the first groove to seal a space between the second profile, the third profile, the second wall, and the cover portion.

[0020] In another example, the gasket portion may include a gasket body and an auxiliary insert member that protrudes from the gasket body toward the profile portion and is inserted into the profile portion.

[0021] In another example, the auxiliary insert member may be formed in multiple pieces and positioned at a corner of the gasket body.

[0022] In another example, the connecting body may have a vertical length corresponding to the vertical length of the first profile, a left-right length corresponding to the left-right length of the second profile, and a front-back length corresponding to the front-back length of the third profile.

[0045] According to one embodiment of the present invention, a storage chamber for equipment may be a chamber filled with gas to store equipment for transporting solar cells. The gas may be nitrogen, but is not limited thereto. A skilled artisan may appropriately select any gas with low reactivity to prevent oxidation of the solar cells located within.

[0046] In addition, the chamber according to one embodiment of the present invention can be used in various ways to prevent oxidation of objects other than solar cells, if there are objects that require oxidation prevention.

[0047] In this specification, the forward / backward, left / right, and up / down directions are referred to for convenience of explanation and may be orthogonal to each other. However, these directions are determined relative to the arrangement of the equipment storage chambers, and the up / down direction does not necessarily imply a vertical direction.

[0048] The equipment storage chamber may be mounted on the upper side of the pedestal as shown in Fig. 1, or may be placed on the ground.

[0049] The equipment storage chamber may include a profile portion (100), a connection portion (200), a cover portion (300), and a gasket portion (400).
