[0009] To explain the technical content, the achieved purposes and effects of the present application in detail, the following will be explained in combination with the embodiments and the accompanying drawings.

[0010] ​In related technologies, the initial pressing of glass laminations mainly employs two methods: vacuuming with rings and extrusion degassing. However, these two methods cannot be applied to the production of extra-large sunroof glass, sunroof glass with notches, glass with large overlap between inner and outer panes, and sunroof products with ambient lighting EVA films. Therefore, there is an urgent need to develop an initial pressing device capable of producing extra-large sunroof products with large notches and large overlaps, achieving high output and high quality. To solve the above technical problems, this invention provides a glass bag-type vacuum initial pressing device, which can control the sealing and opening of the vacuum bag, and perform vacuuming after sealing, thereby realizing the production of sunroof products.

[0011] This application uses the production of automotive sunroof glass as an example to introduce the structure and usage of the glass bag-type vacuum pre-pressing device. The glass bag-type vacuum pre-pressing device provided in this application is not only suitable for automotive sunroof glass production, but also for the production of other glass products, specifically: Please refer to Figure 1 and Figure 2 A glass bag type vacuum initial pressure device includes: a main transmission device 1, which is equipped with a conveying assembly 11; such as Figure 12 and Figure 13 As shown, each transmission node of the conveying assembly 11 is equipped with a bracket 2 and a transmission vacuum component assembly 3; a vacuum bag 7 is provided on the bracket 2. Please refer to... Figure 6 and Figure 7 In this embodiment, the vacuum bag 7 is provided with a buckle 72, which is connected to the bracket 2. The vacuum transfer component 3 docks with the vacuum bag 7 to perform vacuuming. The valve switch component 4 is provided at the front end and the rear end of the conveying component 11 along the conveying direction. The valve switch component 4 at the front end is used to control the vacuum transfer component 3 to start vacuuming. The valve switch component 4 at the rear end is used to control the vacuum transfer component 3 to stop vacuuming. The bag opening device 5 is provided at the front end and the rear end of the conveying component 11. The bag opening device 5 at the front end is used to close the seal of the vacuum bag 7 before vacuuming is started. The bag opening device 5 at the rear end is used to open the seal of the vacuum bag 7 after vacuuming is stopped. By setting up a conveying assembly 11, and setting a set of brackets 2 and a conveying vacuum component assembly 3 at each conveying node of the conveying assembly 11, the brackets 2 are used to place vacuum bags 7 to realize the conveying of vacuum bags 7, and cooperate with the bag opening device 5 to realize the sealing or opening operation of vacuum bags 7. After the vacuum bag 7 is sealed at the front end of the conveying assembly 11, the valve switch assembly 4 controls the conveying vacuum component assembly 3 to evacuate the vacuum bag 7; after the valve switch assembly 4 controls the conveying vacuum component assembly 3 to stop evacuating the vacuum bag 7 at the rear end of the conveying assembly 11, the bag opening device 5 opens the vacuum bag 7 to unload the prepared glass, thereby realizing the production of skylight products.

By arranging multiple sets of translation mechanisms 6 in the conveying direction and arranging the valve switch assembly 4 on the translation mechanism 6, when the vacuum value of the vacuum bag 7 is detected to decrease during the conveying process, the valve switch assembly 4 on the translation mechanism 6 can be controlled to move synchronously with the conveying assembly 11, while the conveying vacuum component assembly 3 is controlled, thereby vacuumizing the vacuum bag 7 to effectively prevent the vacuum value from decreasing; and resetting after the vacuumizing operation is completed. The segmented multi-point docking suction can make the vacuum degree of the whole line in a relatively uniform state, and the vacuum value difference caused by the distance of the vacuum tap is small.

As Figure 3 , Figure 4 and Figure 13As shown, after the movable end of the pressing member 41 moves towards the conveying assembly 11, the vacuum docking component 43 as a whole moves towards the conveying assembly 11, and the vacuum docking component 43 is moved in the x direction or the y direction through the self-adaptive adjusting member 42, so that the positioning member 431 is aligned and positioned with the positioning column 31, the vacuum switch 432 is connected with the vacuum connector 32, and the valve rotating member 433 is connected with the vacuum valve 33; after the vacuum switch 432 is connected with the vacuum connector 32, the elastic mechanism inside the vacuum connector 32 is automatically opened after being pressed by the vacuum switch 432, and at the same time, the vacuum valve 33 is rotated by the valve rotating member 433, so that the transmission vacuum component assembly 3 is connected with the vacuum bag 7, the vacuum channel is completely opened, and the vacuum bag 7 is operated by the vacuum docking component 43; at the same time, when the vacuum operation is completed, the vacuum valve 33 will be closed, so that the transmission vacuum component assembly 3 has a self-sealing effect, which can effectively prevent the vacuum from being lowered in the non-docking state.

[0015] Please refer to Figures 5 to 7 In some embodiments, the bag opening device 5 comprises a bag hook 51, a vertical moving mechanism 52, and a horizontal moving mechanism 53; the horizontal moving mechanism 53 is movably arranged on one side of the vertical moving mechanism 52; the bag hook 51 is movably arranged on the side of the horizontal moving mechanism 53 away from the vertical moving mechanism 52.
