Wherein the product pick-up part 11 is implemented by a magnetic chuck or a pneumatic chuck, which is not limited herein.

The whole working process is further explained by taking the film pressing device provided by the invention as an example in the process of manufacturing the shell-shaped tooth appliance:

the first picking assembly picks up the carrier plate and the film carrying the dental model, which are placed in pairs, from the transmission line, and then moves to the second station 3 and the first station 2 under the driving of a driving mechanism (not shown in the figure) of the first picking assembly. When the first picking assembly carries out picking action, the movable workbench 8 is driven by the first driving device to move to a position where the bearing platform 18 is opposite to the second station 3, at the moment, the connecting part 15 at the lower end of the bearing platform is rapidly connected with the second lifting mechanism 13, and when the first picking assembly moves to the main workbench to prepare for placing a dental jaw model bearing disc and a diaphragm, the second lifting mechanism 13 pushes the bearing platform 18 through the matching action of the connecting part 15, the movable limit block 1604, the fixed limit block 1603, the connecting rod 1602 and the like, and pushes the bearing platform 18 to a position where the top plane of the bearing platform 18 is basically level with the upper surface of the main workbench 1. At this time, the first picking assembly receives the placing command, and places the film into the film accommodating cavity on the film guide 14 at the first station 2; the dental model carrier plate is placed at the second station 3 and is placed directly on the carrier table 18 through the second through hole.

After the membrane and the dental model bearing plate are placed, the second lifting mechanism 13 moves to restore to the initial position, the bearing table 18 also moves downwards to the initial position, and the connection relationship between the lifting mechanism fixedly connected to the bearing table and the second lifting mechanism 13 is released. Meanwhile, the film pressing head 402 in the film pressing assembly 4 is driven by the second driving device 401 to move to the first station 2, and is pressed down to press and fix the film in the film accommodating cavity, at this time, the heating device 19 in the movable working assembly is located at the first station 2, the heating element 1902 in the heating device is started, and the film in the accommodating cavity is heated.

After the membrane is heated, the heating device stops working, and the whole movable working assembly moves along the first guide structure guide rail 1701 through the first driving device translation cylinder 1703, so that the bearing table 18 moves to the first station 2; in the process, the connecting part 15 on the lifting mechanism 16 connected below the bearing table 18 is quickly connected with the first lifting mechanism 9, the first lifting mechanism 9 jacks up the bearing table 18, the bearing table moves into the second through hole at the first station 2, the top surface of the bearing table 18 is flush with the upper surface of the main workbench, and the dental jaw model bearing plate loaded on the bearing table is higher than the upper plane of the main workbench. Furthermore, the first lifting mechanism 9 continues to apply pressure to the bearing platform 18 towards one side of the film pressing assembly 4, and the film is tightly pressed on the dental model bearing plate and the dental model under the common pressure of the film pressing assembly 4 and the first lifting mechanism 9; the first lifting mechanism 9 and the film pressing component 4 can simultaneously apply film pressing pressure to the diaphragm, the dental model bearing plate and the dental model, or the first lifting mechanism 9 slightly lags behind the film pressing component 4; then above-mentioned press mold pressure effect need maintain a period to make the press mold operation more abundant, reduce shell form tooth and rectify bubble on the ware and make shell form tooth and rectify the ware and laminate more with the tooth jaw model, improve shell form tooth and rectify the press mold success rate of ware.

After pressure maintaining is completed, the first lifting mechanism 9 enables the plummer 18 to move towards the direction far away from the main workbench 1 along with the first lifting mechanism 9 through the matching of a limit stop structure of a first quick-release part 901 arranged on the first lifting mechanism and a slot structure of a connecting part 15 arranged on a lifting mechanism 16, and enables the plummer 18 to return to the initial position of the plummer at a first station; meanwhile, the second driving device 401 drives the film pressing head 402 to move upwards and away from the first station, the second picking assembly moves to the first station 2, the dental model with the shell-shaped tooth appliance and the dental model bearing plate are grabbed, and then the dental model and the dental model bearing plate are moved to a transmission line, so that the whole film pressing operation is completed.

Furthermore, when the second picking assembly picks up and transports the dental model and the dental model bearing plate with the shell-shaped tooth appliance, the first picking assembly can open the grabbing work of the next group of diaphragms and the dental model and dental model bearing plate, the actions are circulated again, and the film pressing operation is carried out on the transmission line upper dental model.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, it is still within the scope of the present invention if they fall within the scope of the claims of the present invention and their equivalents.
