Background
In the prior art, an automatic polishing system (polishing machine) for crystal blanks comprises: the feeding station is provided with a feeding mechanism capable of fixing the crystal blank on the clamp; at least one upper hemisphere grinding station for grinding the upper hemisphere of the crystal blank and at least one upper hemisphere polishing station for polishing the upper hemisphere of the crystal blank; the butt joint station is provided with a butt joint mechanism which can transfer and fix the crystal blank onto the other clamp from one clamp and can exchange the positions of the two clamps; at least one lower hemisphere grinding station for grinding the lower hemisphere of the crystal blank and at least one lower hemisphere polishing station for polishing the lower hemisphere of the crystal blank; the blanking station is provided with a blanking mechanism which can detach the crystal blank from the clamp; the grinding mechanism is arranged on each of the upper hemisphere grinding station and the lower hemisphere grinding station, and the polishing mechanism is arranged on each of the upper hemisphere polishing station and the lower hemisphere polishing station. The transfer mechanism for transferring the crystal blanks among the stations is in a mechanical head rotating frame mode, a mechanical arm rotating frame mode and a mechanical arm track mode.
The grinding and polishing process flow of the crystal blank (particularly a standard rhinestone product) is as follows:
feeding (preheating clamp pins comprising empty clamps → dipping powder → bead feeding → bonding) → grinding processing of upper hemisphere → polishing processing of upper hemisphere → butting (preheating clamp pins comprising empty clamps → dipping powder → butting clamp → heating and melting glue for clamp pins of empty clamps to bond crystal blank → heating and glue removing for clamp pins of another clamp → cooling clamp pins to fix bonding) → grinding processing of lower hemisphere → polishing processing of lower hemisphere → blanking (comprising heating and glue removing for clamp → lower bead and cleaning clamp pins). In the process, the butt joint process takes the longest time, the feeding process takes the shortest time, and for the grinding (or polishing) process, a plurality of grinding (or polishing) stations are generally adopted for grinding (or polishing) for a plurality of times in the prior art, so that the grinding (or polishing) process takes the shortest time. How to shorten the time occupied in the butt joint procedure or make the dwell time on each processing station closer through the reasonable distribution of each procedure process, avoid the board latency overlength, improve the machining efficiency of whole automatic grinding and polishing system just is the difficult problem that this trade waited to solve urgently.
Patent document No. CN102366914A discloses an automatic cycle double-clamp ornament grinding and polishing machine, wherein an upper hemisphere grinding and polishing (front grinding and polishing) and a lower hemisphere grinding and polishing (rear grinding and polishing) of a crystal blank are in the same processing cycle (i.e. clamp circulation cycle), wherein clamp seats on each station are arranged in parallel left and right along the length direction of a clamp (especially grinding and polishing stations), so that when a left and right transfer mechanism transfers a clamp between each station, the left and right transfer mechanism needs to stretch down to lift the clamp from the clamp seat of one station, then cross over a clamp seat mechanism on the corresponding station, and then send down to be placed on a clamp seat on the other station, and the left and right transfer mechanism has a complex structure, complicated actions, easy failure and high cost. Moreover, the docking mechanism adopts a 180-degree rotating structure of the docking bracket (namely, the switching component part) and the waiting bracket (namely, the clamp resetting component part), so that the following problems exist: firstly, because the heating pipe in the docking mechanism generally adopts a high-frequency heating pipe or a gas flame-throwing pipe, the heating pipe generally needs to be connected with a high-frequency generating device or a gas supply device, and the heating pipe is installed between two butted clamps (seats), namely, the heating pipe is installed in the adapter assembly, and the frequent rotation of 180 degrees in a large range can cause the connecting structure of the heating pipe and the high-frequency generating device or the gas supply device to be complicated, and the service life is also influenced; secondly, in order to free the rotating space of the switching component, the steel brush and the powder disc used for cleaning the upper clamp and adhering powder and glue are arranged at positions far away from the switching component, and the moving stroke of the steel brush and the powder disc is long and the occupied time is long; thirdly, in the switching assembly, butt joint, powder adhering and gluing and 180-degree rotation are performed in sequence, and much time is occupied, so that the occupied time of a switching (butt joint) station is prolonged, the waiting time of other station mechanisms such as grinding and polishing is prolonged, the butt joint efficiency is low, and the processing efficiency of the whole automatic cycle is reduced.

In the butt joint mechanism, the first front-back transfer mechanism firstly transfers the belt clamp from the butt joint support to the conversion support, then waits for the conversion support to rotate 180 degrees and exchange the up-down position, and then the first front-back transfer mechanism sends the belt clamp on the conversion support to the butt joint support.
