Background
Science and technology guides the continuous change of work and life style of human beings and also continuously improves the quality of work and life of people. Certainly, the higher the technological content is, the more precise the production equipment is required, for example, a finishing carving machine is required in the manufacturing process of producing and processing the display screen glass cover plate, and the operations of perforating, slotting, upper and lower one-time chamfering, special-shaped glass accurate cutting, appearance processing, chamfering and the like of the display screen ultrathin glass are realized by adopting a special diamond grinding head and matching with 24000-40000 r/min high-speed rotation. In order to ensure that the edge of glass is not broken or damaged in the process of fine carving, a designed mold needs to be stably and firmly fixed on a table board of a seat to realize continuous mass production of products, the common method at present is to directly adhere the manufactured mold on the table board of a station seat by using strong glue, then a glass substrate is adsorbed on the surface of the mold through vacuum, then a high-speed grinding head is started, the vacuum is released after the fine carving operation of the glass is finished according to a set program, and the glass substrate is replaced to carry out the next operation.
However, because the size of the display screen is not unique, the sizes of the display screen are usually 5.5 inches, 6.2 inches, 6.6 inches, 8 inches, 10 inches, 13.1 inches, 15.6 inches and even larger, and the molds with corresponding sizes need to be replaced when the glass of the display screen panel with different specifications is processed. The die is made of a hard and brittle resin plate and can be cracked or damaged and scrapped in knocking, so that the die is disposable, and the processing cost of the panel glass is directly increased; meanwhile, in order to ensure the machining precision, the table top of the station seat needs to be polished for the second time and leveled, and the production efficiency is directly reduced due to excessive auxiliary time.
Under the strongly competitive market economic environment, the enterprises are the most feasible way to live only by internal excavation, product processing cost reduction and production efficiency improvement, so panel glass processing enterprises are all striving to find methods.
