Technical Field
The invention belongs to the field of equipment for mask production, and particularly relates to a mask batch temporary storage device and a mask turnover system.
Background
At present, with the high popularization of automation, the production line of the mask (made of glass material) also starts to move to automation and no humanization, and the automatic robot carries and transmits the mask in the whole process. However, in a series of production processes, the time required for completing one mask operation in some processes is short, and the time required for completing one mask operation in some processes is relatively long, which results in product accumulation in some processes. At present, the major processes are long in bottleneck in the cleaning process, the time required by the cleaning process is long (one mask needs about 3 hours), and one mask needs to be cleaned at least twice, and some masks need more, so that products in the cleaning process are accumulated, the blockage of the previous process is caused, and the machine time of equipment in the previous process is wasted. Moreover, when the quantity of orders is large or urgent orders are inserted, if the accumulated products are not processed, the subsequent urgent orders cannot be carried out, so that the ordered delivery cannot be carried out, the loss is brought to customers, and the bad influence is brought to the image of the department.
There are two approaches to solve this problem: firstly, the number of cleaning machines is increased, and the relative cost is increased; another method is to manually take out the accumulated products and temporarily put the products into a box, so that when the machine is released, the products can be made a way for the production of urgent orders, but the method has the defects that a person can dirty the products in the process of lifting the mask plate, the cleaning difficulty is increased, and the risk of falling is caused.
