[0025] In the subsequent description, the suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of describing this utility model, and they do not have a specific meaning in themselves. Therefore, "module" and "component" may be used interchangeably.

[0026] See the appendix Figure 1-2, the present utility model discloses a mask during the transmission of battery wafers, which is used to form a relatively sealed (not completely sealed, with gaps for gas to flow out) chamber on the processing production line of battery wafers, so as to introduce dry gas to dry the carrier plate carrying the battery wafers entering the chamber, which can be understood as air-drying treatment. The mask of this application is the relatively sealed chamber here. The mask is rectangular, including a rectangular top plate 2 connected thereto. Usually, the size of the enclosed rectangle is the same as that of the rectangular top plate 2, so that the two can be fully adapted to form a relatively sealed cover. The mask is arranged on the transportation bottom plate. The transportation bottom plate here can be the floor or other components on the production line. In short, it provides a platform. There is a gap between the bottom of the mask and the transportation bottom plate for the gas in the mask to flow out.

[0027] The rectangle of the mask includes two opposite long sides and two opposite short sides. The long sides are the inlet and outlet side plates, and the short sides are the support side plates. It can be understood that the inlet and outlet side plates are for the battery wafers to enter or leave the mask, and the support side plates mainly play a supporting role. It can also be understood that the path formed by the two inlet and outlet side plates is the transportation path of the battery wafers. Specifically, there are transmission ports 3 for the battery wafers to enter and leave the mask on the inlet and outlet side walls. The battery wafers enter the mask from one of the inlet and outlet side plates and exit the mask from the other inlet and outlet side plate.

[0028] There are several ventilation holes 4 on the rectangular top plate 2. The ventilation holes 4 are used to connect to an external gas supply device, and the external gas supply device is used to provide dry gas. The external gas supply device introduces dry gas into the mask through the ventilation holes 4 to dry the carrier plate, and the excess gas in the mask flows out from the gap between the bottom of the mask and the transportation bottom plate.

[0029] The present utility model sets the mask on the processing production line of battery wafers. There are transmission ports 3 for the battery wafers to enter and leave the mask on the inlet and outlet side plates of the mask. The battery wafers enter the mask from the transmission port 3 of one of the inlet and outlet side plates and exit the mask from the transmission port 3 of the other inlet and outlet side plate, so that the battery wafers can freely pass through the mask during the transportation process; furthermore, dry gas is introduced into the mask through the ventilation holes 4 on the mask to dry the carrier plate.

[0030] Preferably, it includes two inlet and outlet side plates and two support side plates. The inlet and outlet side plates and the support side plates are connected by right-angle connectors 5. For the mask with four side plates, it can be assembled into one through several right-angle connectors 5.

[0031] Another preferred embodiment is that a mask can also have multiple side plates. It can be understood that the above four side plates are assembled to form a side wall unit. Some masks can only include one side wall unit, while larger-sized masks can be provided with multiple side wall units. Specifically, multiple inlet / outlet side plates and / or multiple support side plates are connected by connecting plates to splice multiple inlet / outlet side plates and / or splice multiple support side plates, thereby splicing multiple side wall units.

[0032] Preferably, the transmission port 3 is provided at the top of the inlet / outlet side plate, so that the distance between the battery cell and the ventilation hole 4 in the mask is relatively small, which can accelerate the drying efficiency of the battery cell. In an alternative embodiment, the top of the inlet / outlet side plate can be grooved to form the transmission port 3 between it and the rectangular top plate 2, and the transmission port 3 is located at the top of the inlet / outlet side plate. Preferably, both ends of the transmission port 3 extend to the edge of the inlet / outlet side plate, thereby increasing the width of the transmission port 3.

[0033] Generally, other components are provided on the transportation bottom plate. When the mask is installed on the transportation bottom plate, interference will occur with other components. Therefore, preferably, several avoidance holes 6 are provided at the bottom of the support side plate, and the components on the transportation bottom plate are accommodated in the avoidance holes 6 to avoid interference with the mask.

[0034] Further preferably, the avoidance hole 6 is provided with a cover plate, and the cover plate is a push-pull cover plate or a hinge-opening cover plate. The cover plate is used to control the opening degree of the avoidance hole 6. Thus, the size of the avoidance hole can be adjusted according to different components, and it can also be used as an air outlet of the mask as an auxiliary.

[0035] Preferably, several intersecting ribs 7 are provided on the rectangular top plate 2 to form several grid units. The grid units are rectangular, triangular, or polygonal, and are used to strengthen the rectangular top plate 2.

[0036] Further preferably, a ventilation hole 4 is provided in each grid unit; or, not every grid unit is provided with a ventilation hole 4, but all the ventilation holes 4 are evenly distributed on the rectangular top plate 2.

[0037] Preferably, an inwardly protruding convex member 8 is provided on the inner top of..., and convex members 8 are respectively provided on the four sides of.... The rectangular top plate 2 is placed on the convex members 8, thereby cooperating with... to form a relatively sealed chamber. The convex member 8 can be provided at the four corners or in the middle of.... Alternatively, the convex member 8 is a convex block. In addition, the convex member 8 can also be a convex strip. When it is a convex block, multiple convex blocks can be provided on each side wall of... to ensure the stability of the rectangular top plate 2.

[0038] Further preferably, a limiting member protruding inward is provided at the inner top, and the limiting member is arranged on the upper part of the rectangular top plate 2 for restricting the upward movement of the rectangular top plate 2. Optionally, the limiting member can be in the form of a button. When installing the rectangular top plate 2, applying force to the limiting member can press the limiting member into it; when the installation of the rectangular top plate 2 is completed, the limiting member pops out from the inside to limit the rectangular top plate 2.

[0039] It should be noted that the embodiments of the present invention have good implementability and do not impose any form of limitation on the present invention. Any person skilled in the art may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, as long as the content of the technical solution of the present invention is not departed from, any modification, equivalent change or modification made to the above embodiments according to the technical essence of the present invention still falls within the scope of the technical solution of the present invention.
