[0050] The working process of this embodiment:

[0051] The fixture transfer assembly 2 runs on the circular track 1 and stops when it reaches the automatic loading station 3. Then the first lifting electric cylinder 34 of the automatic loading station 3 extends upward, and the first fixture top plate 37 contacts and ventilates the fixture lifting plate 23. Under the action of air pressure, the lifting and locking device 210 opens, and the first lifting electric cylinder 34 continues to extend, driving the fixture 212 to move upward. The first opening and closing electric cylinder 38 opens the fixture 212, and the product is then loaded onto the fixture 212. After that, the first lifting electric cylinder 34 retracts, and the fixture 212 descends to the specified position. Then the air pressure is turned off, the lifting and locking device 210 is locked, and the fixture 212 no longer moves. The fixture transfer assembly 2 starts to move to the processing station 5.

[0052] After the jig transfer assembly 2 arrives at the processing station 5, the circular track 1 track change mechanism 12 pushes the jig transfer assembly 2 into the processing station 5, and the second screw module 53 moves upward to drive the second cavity support bracket 52 to lift the lower cavity 21 and the upper cavity 56 to close. The two cavities are separated by the product film material to form an independent chamber. Then the upper and lower chambers are evacuated, and the infrared heating device moves to the predetermined position under the action of the linear module 58. When the production environment reaches the preset value, the electric cylinder 54 will extend, and the third jig top plate 55 will contact the jig lifting plate 23 for ventilation. Under the action of air pressure, the lifting and locking device 210 opens, and the electric cylinder 54 continues to extend, driving the jig 212 to move upward to the fitting position for fitting. After the bonding is completed, the electric cylinder 54 retracts, the fixture 212 descends to the specified position, and then the air pressure is turned off, the lifting locking device 210 is locked, the fixture 212 no longer moves, and the fixture transfer assembly 2 starts to move to the automatic unloading station 4. It should be pointed out that before the fixture transfer assembly 2 moves to the unloading station, the remaining fixture transfer assemblies 2 can all pass through the circular track 1 normally to other stations.

[0053] The fixture transfer assembly 2 stops when it reaches the automatic unloading station 4, and then the first screw module 43 of the automatic unloading station 4 extends upward, the top plate contacts and ventilates the fixture lifting plate 23, and under the action of air pressure, the lifting and locking device 210 opens, the first screw module 43 continues to move upward, driving the fixture 212 to move upward, the second opening and closing electric cylinder 48 opens the fixture 212, and the product is loaded and unloaded from the fixture 212. After that, the second lifting electric cylinder 46 retracts, the fixture 212 descends to the specified position, and then the air pressure is turned off, the lifting and locking device 210 is locked, the fixture 212 no longer moves, and the fixture transfer assembly 2 starts to circulate to the automatic loading station 3.
