Damaged mask rejecting device

Abstract

The invention discloses a damaged mask rejecting device applied to a mask production line. The damaged mask rejecting device comprises a detector, a rejector and a controller; the detector comprises acamera installed above the tail end of the mask production line and a backlight source directly facing the camera, and the camera has a downward detection direction perpendicular to a mask conveyingdirection; the rejector comprises a first push plate and a driver, the first push plate is located over the tail end of the mask production line and located in front of the camera in the mask conveying direction, and the driver is in linkage with the first push plate to drive the first push plate to reciprocate up and down at an angle perpendicular to the mask conveying direction; and the controller is connected with the detector and the rejector to receive detection data obtained by shooting of the camera and generate an instruction according to the detection data to control the rejector to execute a corresponding operation. The damaged mask rejecting device can automatically reject unqualified masks and improve the mask production efficiency.

Description

technical field [0001] The invention relates to the technical field of mask production, in particular to a device for removing bad parts of masks. Background technique [0002] Because masks cover the mouth and nose, they can effectively prevent pollutants such as external viruses from entering the body through breathing, and can also prevent the spread of droplets from affecting the health of others. Therefore, masks have gradually become a necessity in people's lives. [0003] Due to the short protection time of existing masks, general medical masks need to be replaced after 4 hours of accumulated use, so the supply demand for masks in the market is very large; and most of the current masks rely on fully automatic mechanized production, mask production machines After debugging, it can produce hundreds or even thousands of masks in one minute, so as to meet market demand. [0004] However, although the use of mask machines to produce masks has greatly improved productivity...

Problems solved by technology

[0004] However, although the use of mask machines to produce masks has greatly improved productivity, the quality inspection work after mask production is still not in place, and a large amount of labor is required to visually inspect the appearance of the masks one by one to check whether the appearance of the masks is damaged, etc. In abnormal situations, if abnormal masks are found, they need to be manually removed. This process seriously reduces the production efficiency of masks, resulting in a large number of masks that cannot be put on the market in time; Unqualified quality, endangering the health and safety of users
