[0032] This utility model discloses a blue film taping machine, which includes an automatic crystal ring changing mechanism 100 as described above, and realizes automatic crystal ring changing operation through the automatic crystal ring changing mechanism 100.

[0033] The specific working process of the automatic crystal ring changing mechanism and blue film taping machine of this utility model is as follows: When it is necessary to load the crystal ring 40, the transverse drive mechanism 32 drives the crystal ring clamping mechanism 34 to move to the side of the lifting rack assembly 10. The crystal ring clamping mechanism 34 clamps the crystal ring 40 on the loading position of the rack body 13. Then, the transverse drive mechanism 32 drives the crystal ring clamping mechanism 34 to transfer the clamped crystal ring 40 between the fixed pressure plate 242 and the movable pressure plate 243. Then, the transverse drive mechanism 32 drives the crystal ring clamping mechanism 34 to reset to the initial position. At the same time, the second lifting drive structure drives the movable pressure plate 243 to move closer to the fixed pressure plate 242, thereby clamping the crystal ring 40 set between the two. Then, the X-axis motion drive mechanism 21 and the Y-axis motion drive mechanism 22 cooperate to transfer the pressure plate mechanism 24 holding the crystal ring 40 to the die bonding station for die bonding, thereby realizing the loading operation of the crystal ring 40. When the crystal ring 40 needs to be unloaded, the X-axis motion drive mechanism 21 and the Y-axis motion drive mechanism 22 work together to reset the crystal ring 40, which has been die-bonded on the pressure plate mechanism 24, to its initial position. Then, the second lifting drive structure drives the movable pressure plate 243 to move away from the fixed pressure plate 242, while the lateral drive mechanism 32 drives the crystal ring clamping mechanism 34 to move and transfer the crystal ring 40, which has been die-bonded between the fixed pressure plate 242 and the movable pressure plate 243, to the material rack body 13, thereby completing the unloading operation of the crystal ring 40. Then, the first lifting drive mechanism 11 drives the material rack body 13 to move upward by a distance, and the new crystal ring 40 moves to the loading position of the material rack body 13. This cycle is repeated to complete the automatic crystal ring changing operation.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
