Crystal blank automatic grinding and polishing system and its left and right transfer mechanism

Abstract

The invention discloses a lateral transfer mechanism for an automatic crystal blank grinding and polishing system. The lateral transfer mechanism comprises a plurality of transfer manipulators for pushing fixtures between adjacent positions and a track which extends laterally and linearly, the track is erected on a feeding and blanking machine, a grinding and polishing machine and a butt joint machine, the plurality of transfer manipulators move along the track under the drive of a transfer driving device, fixture seats which are arranged on the feeding and blanking machine, the grinding and polishing machine and the butt joint machine and used for installation of fixtures are laterally arranged in rows along fixture length directions, and the plurality of transfer manipulators push the fixtures along the fixture length directions to slide between laterally adjacent fixtures. The invention further discloses the automatic crystal blank grinding and polishing system using the lateral transfer mechanism. According to the automatic crystal blank grinding and polishing system and the lateral transfer mechanism thereof, the structure is reasonable, actions are simple, the cost is low, the operation is reliable, and the machining efficiency and the reliability of the whole automatic grinding and polishing system are further improved.

Description

technical field [0001] The invention belongs to the field of grinding and polishing processing of crystal products, and relates to an automatic grinding and polishing system for crystal blanks for automatic grinding and polishing processing of crystal blanks, in particular to a left-right transfer mechanism therein. 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; at least one lower hemis...

Problems solved by technology

[0005] Publication No. CN102366914A discloses a kind of automatic cycle double-clamp jewelry polishing machine in the patent literature, the upper hemisphere grinding and polishing (front grinding and polishing) and the lower hemisphere grinding and polishing (back grinding and polishing) of the crystal blank are performed in the same processing cycle ( That is, the fixture circulation cycle), wherein the fixture seats on each station are arranged in parallel to the left and right along the length direction of the fixture (especially the grinding and polishing station), so that when the left and right transfer mechanism transfers the fixture between the stations, it needs to be extended first. Lift the fixture from the fixture seat of one station and then step over the fixture seat mechanism on the corresponding station, and then send it down and place it on the fixture seat of another station. Cumbersome, prone to failure and high cost

Moreover, the docking bracket (i.e. the adapter assembly part) and the waiting bracket (i.e. the clamp reset assembly part) are both 180 ° rotating structures in its docking mechanism, so there are the following problems: one, because the heating tube in the docking mechanism is generally High-frequency heating tubes or gas flame-throwing tubes are used, so the general heating tubes need to be connected with high-frequency generating equipment or gas supply equipment, etc., and the heating tubes should be installed between the two docking fixtures (seats), that is, installed on the above-mentioned In the adapter assembly, frequent rotations in a wide range of 180 degrees will complicate the connection structure between the heating tube and high-frequency generating equipment or gas supply equipment, and affect the service life; secondly, in order to free up the rotation space of the adapter assembly, The wire brushes and powder discs used for cleaning the upper fixtures and dipping and gluing are set far away from the adapter assembly. Their moving strokes are long and take up a lot of time; Powder gluing and 180-degree rotation are carried out successively, which takes up a lot of time, so that the transfer (docking) station takes longer, the waiting time of other grinding and polishing station mechanisms is prolonged, and the docking efficiency is low. Processing efficiency of automatic cycle

[0007] But the above-mentioned structure is that the fixture seats on each station are arranged parallel to the left and right along the length direction of the fixture (especially the grinding and polishing station), so that when the left and right transfer mechanism transfers the fixture between the stations, it needs to be stretched down from one station to the other. Lift the fixture on the fixture seat of the station, and then step over the fixture seat mechanism on the corresponding station, and then send it down and place it on the fixture seat of another station. Such a left-right transfer mechanism is complicated in structure, cumbersome and easy Faulty and costly

In its docking mechanism, the first front and rear transfer mechanism needs to transfer the belt clamp from the docking bracket to the conversion bracket, 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 material on the conversion bracket The jig with glue 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.
