Description

Burnishing machine discharges auto-change over device

Technical Field

The application relates to the technical field of polishing machines, in particular to a polishing machine discharge switching device.

Background

The polisher is an electric tool and consists of basic elements such as a base, a polishing disc, a polishing fabric, a polishing cover and a cover.

The utility model relates to an auxiliary device of a polishing machine (one of flat panel display device production equipment), which is used for continuously pouring polishing liquid when a glass substrate is polished, simply washing the glass substrate at the same station after polishing, and sharing a water tank and a discharge pipeline. The polishing solution needs to be recycled, the flushing water is discharged, and the discharge switching device enables the polishing solution to flow into the circulating system during polishing and enables the water used for cleaning to be discharged during cleaning, and the function of the discharge switching device is similar to that of a three-way valve controlled in real time.

Two sets of schemes have been used for the discharge switching device on the polishing machine, one scheme is as follows: the pneumatic control three-way valve is adopted for switching control, and the pneumatic control three-way valve has the advantages that the structure is compact, fluid flows in a closed pipeline, no fluid is splashed out, and the defects that polishing solution is easy to precipitate, precipitates clamp a valve core, the switching action is failed, the failure is difficult to find, the maintenance cost is high, and the operation is abandoned; the scheme that uses now comprises shunt, slip table cylinder and support, and the motion of slip table cylinder drive shunt can stop at two definite positions, and two mouths pass through the hose and connect polishing solution circulation system and drainage system respectively, and the shunt is divided into two chambeies, and during the polishing, the cavity of one side removes to equipment drain pipe below, and polishing solution flows out from the polishing solution discharge port, gets into circulation system, and during the washing, the cavity of opposite side removes to equipment drain pipe below, and washing water flows out from wasing the water discharge port, gets into the sewer system.

Polishing solution and water discharge impulse in a discharge switching device on the existing polishing machine generate flow sputtering, the movement of a flow divider can also generate sputtering, the sputtering falls on a cylinder guide rod and the ground to pollute the environment and the device, and the polishing solution splashes on a cylinder to form deposition of polishing powder to accelerate the abrasion of the cylinder so as to damage the cylinder. The hose connecting the discharge port with the circulation system and the drainage system moves with the diverter at a high frequency and is easy to damage, and mainly because of the structural reason, the sealing is not easy to realize.
