Crystal blank automatic grinding and polishing system and its docking mechanism

Abstract

A docking mechanism comprises a docking rack. A docking position, a switching position and a powder pick-up position are disposed on the docking rack. The docking position and the switching position are disposed in a column in a front-and-back manner, and the docking position and the powder pick-up position are disposed in a row in a left-and-right manner. A docking support is fixedly mounted at the docking position. A docking assembly is disposed on the docking support. A switching support is disposed at the switching position, and the switching support rotates around a horizontal shaft. A powder pick-up support is disposed at the powder pick-up position, and the powder pick-up support rotates around a horizontal shaft. The powder pick-up support and the docking support are disposed in a gantry manner. A left transfer mechanical arm and a right transfer mechanical arm are disposed below the powder pick-up support and the docking support. A front transfer mechanical arm and a rear transfer mechanical arm are disposed on the docking support. Also disclosed is a crystal blank automatic polishing system using the docking mechanism. According to the technical solution, docking accuracy and the degree of bonding firmness of a crystal blank can be ensured, a docking station is proper in structure, docking efficiency is improved, and the machining efficiency of the whole automatic polishing system is improved.

Description

technical field [0001] The invention belongs to the field of grinding and polishing of crystal products, and relates to an automatic grinding and polishing system for crystal blanks for automatic grinding and polishing of crystal blanks, in particular to a docking mechanism for the automatic grinding and polishing system for crystal blanks. Background technique [0002] In the prior art, the automatic grinding and polishing system (grinding and polishing machine) of crystal blanks includes: a feeding station, which is provided with a feeding mechanism capable of fixing the crystal blanks on the fixture; The upper hemisphere grinding station for grinding the hemisphere and at least one upper hemisphere polishing station for polishing the upper hemisphere of the crystal blank; the docking station is provided with the ability to transfer and fix the crystal blank from a fixture to On the other fixture, a docking mechanism capable of exchanging the positions of the two fixtures;...

AI Technical Summary

Problems solved by technology

[0010] The above-mentioned docking mechanism adopts the docking bracket (that is, the transfer component part) and the waiting bracket (that is, the clamp reset component part) are both 180 ° rotation structures, so there are the following problems: First, because the heating tube in the docking mechanism generally adopts high High-frequency heating pipe or gas fire pipe, so the general heating pipe needs to be connected with high-frequency generating equipment or gas supply equipment, etc., and the heating pipe should be installed between the two docking fixtures (seats), that is, installed on the above-mentioned transfer In the component, frequent rotation in a wide range of 180 degrees will complicate the connection structure between the heating tube and the high-frequency generating equipment or gas supply equipment, etc., and also affect the service life; The wire brushes and powder discs for upper fixture cleaning and powder coating are set far away from the adapter assembly. Their moving strokes are long and take up a lot of time; The gluing and 180-degree rotation are carried out successively, which takes up a lot of time, which makes the transfer (docking) station take longer, the waiting time of other grinding and polishing station mechanisms is prolonged, and the docking efficiency is low, which also reduces the efficiency of the entire automatic cycle. Processing efficiency

However, in the above structure, the first front and rear transfer mechanism needs to transfer the tape fixture from the docking bracket to the conversion bracket first, and then wait for the conversion bracket to rotate 180 ° after the upper and lower positions are reversed, and then the first front and rear transfer mechanism will transfer the belt on the conversion bracket The glue jig is sent to the docking bracket. During this process, the first front and rear transfer mechanism reciprocates the jig, and the docking bracket can only be in a waiting state, which increases the waiting time of the machine, so further improvements are needed to increase production efficiency.
