However, in the process of making such "super-large-sized and super-large-curved vehicle-mounted 3D curved glass", due to its large size, it is impossible to use traditional small-sized glass hot forming equipment for production, because traditional small-sized glass hot forming equipment uses a certain pressure on the upper and lower molds to squeeze the glass to achieve glass forming, but when hot bending large-sized and large-curved glass, it is usually pre-formed to obtain semi-finished glass, and then shaped.

[0046] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0047] The lifting mechanism, glass forming device and glass hot bending equipment according to the present application are described below with reference to the accompanying drawings.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting mechanism of the present application includes a frame 10, a mounting base 20 and a plurality of telescopic arms 40; wherein, the plurality of telescopic arms 40 are distributed corresponding to the corners of the mounting base 20; the fixed end of each telescopic arm 40 is detachably connected to the frame 10, and the movable end of each telescopic arm 40 is connected to an angle adjustment structure capable of multi-angle adjustment, and the ends of part or all of the angle adjustment structures are also connected to a cross guide rail assembly 50; the cross guide rail assembly 50 is connected to the corresponding corners; the angle adjustment structure not equipped with a cross guide rail assembly 50 is directly connected to the corresponding corner.

[0049] Among them, each telescopic arm 40 can move in the height direction to adjust the position of the mounting seat 20 in the height direction; the cross rail assembly 50 can adjust the position of the mounting seat 20 in the horizontal plane, and the angle adjustment structure can fine-tune the spatial angle of the mounting seat 20. When the lifting mechanism of the present application is used to adjust the position of the mounting seat 20, the multi-angle lifting and lowering adjustment of the four corners of the mounting seat 20 can be achieved through the cooperation of the angle adjustment structure, the telescopic arm 40 and the cross rail assembly 50. In the glass forming process, the mounting seat 20 drives the adjustment of the position of the shaping upper mold 60 in the height direction, so as to ensure the mold closing accuracy of the shaping upper mold 60 and the hollow lower mold, thereby improving the fitting accuracy of the shaping upper mold 60 and the spherical semi-finished glass.

[0050] In some embodiments, the movable end of one telescopic arm 40 is connected to the corresponding corner portion via an angle adjustment structure, and the movable ends of the remaining telescopic arms 40 are connected to the corresponding corner portions via a cross rail assembly 50 .

[0051] At one corner, the mounting base 20 is directly connected via the angle adjustment structure, and the mounting base 20 can be directly adjusted to a large angle or a small angle by the angle adjustment structure. At the other three corners, the angle adjustment structure is connected to the mounting base 20 via the cross rail assembly 50, so that the mounting base 20 can be fine-tuned in a small range in the x and y linear directions, and the mounting base 20 can be adjusted to a large angle or a small angle at the same time.

[0052] In some embodiments, each telescopic arm 40 includes a linear drive assembly and a lifting connection seat 41, and the lifting connection seat 41 is connected to the moving end of the linear drive assembly and is suitable for forming a telescopic end. When the moving end of the linear drive assembly moves in the height direction, it can drive the lifting connection seat 41 to move, thereby realizing the telescopic movement of the entire telescopic arm 40 in the height direction, so as to facilitate the height direction position adjustment of the mounting seat 20.

[0053] In some embodiments, the angle adjustment structure includes a lifting hinge seat 30 , one side of the lifting hinge seat 30 is connected to the mounting seat 20 or the cross rail assembly 50 , and the other side is hinged to the bottom end of the lifting connection seat 41 .

[0054] Among them, Figure 5 As shown, the lifting hinge seat 30 includes a fisheye joint 31, a hinge seat shaft 32, a hinge seat retaining spring 33 and a hinge seat base 34. The fisheye joint 31 can realize a large-scale rotation adjustment with the hinge seat shaft 32 as the axis, and can realize a small-scale angular movement with the floating connecting ball (i.e., the "fisheye") inside the fisheye joint 31 as the sphere center.

[0055] On the mounting seat 20, the three corners connected to the linear drive assembly can be fine-tuned in the x and y linear directions, adjusted in a large angle with the capstan shaft 32 as the axis, and adjusted in a small angle with the floating connection ball inside the fisheye joint 31 as the ball center. The other connection angle can be adjusted in a large angle with the capstan shaft 32 as the axis, and adjusted in a small angle with the floating connection ball inside the fisheye joint 31 as the ball center. Through the above adjustment method, the horizontality of the mounting seat 20 can be adjusted.

[0056] In some embodiments, the linear drive assembly includes a support seat 42, a slide rail 43, a rotating screw 44 and a rotating drive member 45, the support seat 42 is installed on the frame 10; the slide rail 43 is configured on the support seat 42 along the telescopic direction of the telescopic arm 40; the rotating screw 44 is rotatably set in the slide rail 43; the rotating drive member 45 is set on the support seat 42 and is drivingly connected to the rotating screw 44; the lifting connecting seat 41 is slidably connected to the slide rail 43 and is threadedly connected to the rotating screw 44.

[0057] The rotary drive member 45 is preferably a rotary motor, and the driving end of the rotary motor is connected to the end of the rotary screw 44. When the rotary motor is turned on, the rotary motor can drive the rotary screw 44 to rotate. When the rotary screw 44 rotates, the rotary screw 44 drives the lifting connection seat 41 to slide along the slide rail 43 in the height direction. Since the bottom end of the lifting connection seat 41 is connected to the lifting hinge seat 30, the position adjustment of the mounting seat 20 in the height direction can be indirectly driven.

[0058] In addition, if Figure 4 As shown, the cross rail assembly 50 includes:

[0059] The first guide rail 51 is provided with a first slider 53 slidably disposed along the length direction;

[0060] A second guide rail 52 is stacked and cross-arranged with the first guide rail 51, and a second slider 54 is slidably disposed on the second guide rail 52 along the length direction; and

[0061] The connecting seat 55 is disposed between the first guide rail 51 and the second slider 54 . The lower end surface of the first guide rail 51 is fixedly connected to the connecting seat 55 , and the upper end surface of the second slider 54 is fixedly connected to the lower surface of the connecting seat 55 .

[0062] The upper surface of the first slider 53 is fixedly connected to the bottom of the hinge seat base 34, the first guide rail 51 is fixed to the upper surface of the connection seat 55, the second slider 54 is fixed to the lower surface of the connection seat 55, and the second guide rail 52 is fixed to the mounting seat 20. When the lifting hinge seat 30 rotates relative to the bottom end of the lifting connection seat 41, the first slider 53 can be driven to slide along the first guide rail 51, and the second slider 54 can be driven to slide along the second guide rail 52. Since the first guide rail 51 and the second guide rail 52 extend in the x and y directions respectively, the position adjustment of the mounting seat 20 in the x and y directions is realized.

[0063] like Figure 1 As shown, the present application also proposes a glass forming device, which cooperates with the hollow lower mold of the glass hot bending equipment, and the glass forming device includes:

[0064] A shaping upper mold 60, the bottom surface of which is a convex spherical surface and can be adapted to absorb the spherical semi-finished glass on the hollow lower mold;

[0065] A heating mechanism is located in the shaping upper die 60 and heats the shaping upper die 60;

[0066] A lifting mechanism as described above;

[0067] The shaping upper die 60 is installed on the mounting seat 20 of the lifting mechanism, and the shaping upper die 60 and the telescopic arm 40 of the lifting mechanism are distributed on both sides of the mounting seat 20 of the lifting mechanism.

[0068] The shaping upper die 60 is connected to the telescopic arm lifting drive on the lifting mechanism, so that the mold parallelism between the shaping upper die 60 and the hollow lower die can be adjusted.

[0069] Specifically, in Figure 1 and Figure 2 Among the four groups of telescopic arms 40 shown: three groups of telescopic arms 40 are connected to the three corners of the mounting seat 20 through three groups of "adjustment mechanisms of the lifting capstan 30 and the cross-guide assembly 50 installed in series", respectively, so that the three corners connected to the linear drive assembly can be fine-tuned in the x and y linear directions, large-scale angular adjustment with the capstan shaft 32 as the axis, and small-scale angular adjustment with the floating connection ball inside the fisheye joint 31 as the ball center. Another group of telescopic arms 40 is directly connected to the last corner of the mounting seat 20 through the lifting capstan 30, so that large-scale angular adjustment with the capstan shaft 32 as the axis, and small-scale angular adjustment with the floating connection ball inside the fisheye joint 31 as the ball center can be performed, thereby realizing that the horizontality of the shaping upper mold 60 can be adjusted based on the heating mechanism during the shaping and heating process of the shaping upper mold 60.

[0070] In addition, it should be noted that when the height direction of the mounting base 20 is adjusted by using the lifting mechanism, there are four lifting modes:

[0071] (1) Rapid lifting (manual / automatic mode)

[0072] When the glass forming device controls the mounting seat 20 to perform long-distance lifting (single lifting stroke exceeds 50mm), the lifting mechanism will adopt the "fast lifting" mode. During the "fast lifting" process, the four rotating motors open the brakes at the same time and run synchronously at the fastest speed; the four sets of telescopic arms 40 start running at the same time and lift synchronously, controlling the mounting seat 20 to reach the specified position at the fastest speed.

[0073] (2) Precision lifting (manual / automatic mode):

[0074] When the glass forming device controls the mounting seat 20 to perform a short-distance lifting (single lifting stroke does not exceed 50mm), the lifting mechanism will adopt the "precision lifting" mode. During the "precision lifting" process, the four rotating motors open the brakes at the same time and run synchronously at a slow speed; the four sets of telescopic arms 40 start running at the same time and lift synchronously, controlling the mounting seat 20 to lift and lower to the specified position at a relatively slow and precise speed.

[0075] (3) Fine-tune the lifting and lowering (manual / automatic mode):

[0076] When the mold is replaced or the machine is used for a long time, if the horizontal parallelism between the mounting base 20 and the hollow lower mold fluctuates, a person is required to manually calibrate the parameters and positions of the telescopic arm 40 in a "fine-tuning lifting" manner through manual mode.

[0077] ① Before fine-tuning the lifting and lowering: First, manually operate and start the four rotating motors at the same time to control the lifting connection seats 41 on the four telescopic arms 40 to "rapidly descend", thereby controlling the four corners of the mounting seat 20 to "rapidly descend"; thereby controlling the shaping upper mold 60 suspended on the mounting seat 20 to "rapidly descend" to a height close to the mold closing with the hollow lower mold and maintain a certain distance. At this time, the height distances between the four corners of the mounting seat 20 and the glass plate placement surface on the hollow lower mold are "height 1", "height 2", "height 3" and "height 4" respectively.

[0078] ②. When fine-tuning the lifting: For the convenience of explanation, the four rotating motors are named rotating motor 1, rotating motor 2, rotating motor 3, and rotating motor 4, and the corresponding telescopic arms 40 are named telescopic arms 40-1, telescopic arms 40-2, telescopic arms 40-3, and telescopic arms 40-4, respectively.

[0079] I. The rotating motor 1 is turned off, the internal brake of the rotating motor is started, and the lifting connection seat 41 of the telescopic arm 40-1 corresponding to the rotating motor 1 is fixed, and the "height 1" remains fixed accordingly.

[0080] II. The rotating motors 2, 3 and 4 start running at the slowest speed, and the internal brakes of the rotating motors are closed. The lifting connection bases 41 on the telescopic arms 40-2, 40-3 and 40-4 are controlled respectively to move a small distance.

[0081] III. Thus, the height distances between the upper left corner, lower left corner, upper right corner, and lower right corner of the mounting seat 20 and the placement surface of the glass plate on the hollow lower mold - "height 2", "height 3", and "height 4" are all moved toward "height 1".

[0082] IV. When the height distances of the upper left corner, lower left corner, upper right corner, and lower right corner of the mounting seat 20 and the placement surface of the upper glass plate of the hollow lower mold - "height 1", "height 2", "height 3", and "height 4" are all equal, the shaping upper mold 60 is parallel to the horizontal placement surface of the upper glass plate of the hollow lower mold.

[0083] V. Finally, the shaping upper mold 60 and the hollow lower mold are molded together through manually controlled precise lifting, and the fine-tuning lifting is completed.

[0084] ③. After the fine-tuning and lifting is completed: record the data parameters during the fine-tuning and lifting process and save them in the touch screen of the equipment; the saved data parameters can be used to control the lifting mechanism on the glass molding device to automatically fine-tune and lift, and automatically calibrate the mold closing accuracy.

[0085] (4) Fully automatic lifting (fully automatic mode):

[0086] After the fine adjustment of the horizontal parallelism of the shaping upper die 60 and the hollow lower die is completed through fine adjustment of lifting, the equipment enters the fully automatic lifting mode. During the fully automatic lifting process, each lifting movement includes the above three lifting modes - fast lifting, fine adjustment lifting, and precision lifting, and all are fully automatically controlled.

[0087] ① Before fully automatic lifting:

[0088] I. After the shaping upper die 60 is manually suspended and mounted on the mounting base 20, the shaping upper die 60 is "quickly lifted" to the "standby position" by controlling the four sets of telescopic arms 40 through manual operation. Figure 1 The position of the shaping upper mold 60 when the glass sheet is loaded is shown.

[0089] II. Manual mode operation is performed manually to control the four sets of telescopic arms 40 to complete the calibration of the horizontal parallelism between the shaping upper mold 60 and the hollow lower mold through "fine adjustment lifting (manual mode)".

[0090] III. After completing the calibration of horizontal parallelism, a mold closing test is performed. If the shaping upper mold 60 can be closed with the hollow lower mold, the shaping upper mold 60 is controlled to "rapidly lift" to the "standby position" by manual mode operation, and the whole machine enters the "full-automatic lifting" mode.

[0091] ②. When performing fully automatic lifting:

[0092] I. The glass sheet is manually loaded, and the shaping upper mold 60 and the mounting seat 20 are kept in the "standby position".

[0093] II. In the self-weight preforming / shaping upper mold 60 heating process: the preheating and holding furnace moves to the self-weight preforming station, and the upper mold heating furnace moves to the heating position of the shaping upper mold 60; the machine program automatically controls the four sets of telescopic arms 40 to "quickly drop" the shaping upper mold 60 to the heating height position of the heating mechanism, and the heating mechanism starts heating.

[0094] III. After the self-weight preforming / shaping upper mold 60 heating process is completed, the machine program automatically controls the four sets of telescopic arms 40 to "quickly lift" the shaping upper mold 60 to the "standby position".

[0095] IV. In the shaping process: after the preheating and holding furnace moves to the shaping station, the machine program automatically controls the four sets of telescopic arms 40 to "rapidly descend" to a height where the shaping upper mold 60 and the hollow lower mold are close to the mold closing, but maintain a certain distance.

[0096] V. The machine program automatically controls the four sets of telescopic arms 40, so that the shaping upper mold 60 completes the automatically controlled "fine adjustment lifting"; through the automatically controlled "precision descent", the shaping upper mold 60 is molded with the hollow lower mold. During the mold closing process, the vacuum adsorption function of the glass forming device is turned on to provide vacuum adsorption force for the shaping upper mold 60, completing the high-temperature adsorption of the spherical semi-finished glass.

[0097] VI. After the shaping process is completed: the machine program automatically controls the four sets of telescopic arms 40 to make the shaping upper mold 60 and the finished glass or spherical semi-finished glass adsorbed thereon be first "precisely lifted" and separated from the hollow lower mold, and then "quickly lifted" to the "standby position".

[0098] VII. In the temperature compensation process (if there is no such process, the finished glass will be directly transferred to the cooling telescopic line process): the preheating and insulation furnace moves back to the self-weight preforming station, and the upper mold heating furnace moves back to the shaping upper mold 60 heating position; the machine program automatically controls the four sets of telescopic arms 40 to "rapidly descend" the spherical semi-finished glass adsorbed by them to the heating height position of the heating mechanism. The heating mechanism restarts heating to perform temperature compensation on the spherical semi-finished glass.

[0099] VIII. After the temperature compensation process is completed: the machine program automatically controls the four sets of telescopic arms 40 to "quickly lift" the shaping upper mold 60 and the finished glass adsorbed thereon to the "standby position".

[0100] IX. In the process of transferring finished glass to the cooling telescopic line: the machine program automatically controls the four sets of telescopic arms 40 to first "rapidly lower" the shaping upper mold 60 and the finished glass adsorbed thereon; the lower surface of the finished curved glass is "rapidly lowered" to a height position where it is about to contact the upper surface of the cooling telescopic line, but still maintains a short distance. Then, the shaping upper mold 60 and the finished glass adsorbed thereon are "precisely lowered" to the lower surface of the finished glass, "precisely lowered" to the "finished glass unloading position" where it fits the upper surface of the cooling telescopic line but does not apply pressure.

[0101] The vacuum adsorption function of the glass forming device is turned off, the vacuum is broken, and the shaping upper mold 60 places the finished glass on the telescopic roller line extending from the cooling telescopic line.

[0102] X. After the finished glass is transferred to the cooling telescopic line, the machine program automatically controls the four telescopic arms 40 to "quickly lift" the shaping upper mold 60 to the "standby position". Then, the telescopic roller line on the cooling telescopic line retracts to its original position.

[0103] Finally, after the finished glass is cooled and discharged, the next round of production and the next round of fully automatic lifting and lowering of the glass forming device are repeated.

[0104] In summary, the present application uses a lifting mechanism to achieve precise adjustment of the mold closing of the hollow lower mold and the shaping upper mold 60, so that the curvature of the final finished curved glass is closer to the target curvature, which is suitable for the production of large-size and ultra-large curvature finished curved glass.

[0105] In some embodiments, the glass forming device also includes multiple counterweight mechanisms 70, multiple sets of telescopic arms 40 are distributed around the periphery of the counterweight mechanism 70, and the counterweight mechanism 70 includes a counterweight cylinder, which is pivotally connected to the hinge base 34 through a hinge shaft 32, and the hinge base 34 is installed on the mounting base 20.

[0106] Since the weight of the mounting seat 20 and the shaping upper die 60 can be up to 3 tons, it is necessary to fill the air inlet of the piston rod of the four counterweight cylinders with compressed air of constant pressure to balance the gravity, thereby reducing the load of the rotating screw 44 on the lifting mechanism and ensuring the service life and lifting accuracy of the rotating screw 44. Among them, the counterweight cylinder adopts a large heavy-duty cylinder to balance the gravity of the mounting seat 20 and the shaping upper die 60 installed at the bottom of the mounting seat 20. In addition, a check valve is also provided on the counterweight cylinder to prevent the counterweight cylinder from causing the internal compressed air to flow back due to the inability to bear the load, and to avoid the relative movement of the piston rod and the cylinder body after overload.

[0107] In some embodiments, a vacuum port is opened on the shaping upper mold 60, and the glass forming device also includes a vacuum condenser and a water channel joint; the vacuum condenser includes an outer tube and an inner tube nested in sequence from the inside to the outside, the inner tube is connected to the vacuum port for vacuum extraction, and cooling circulating water is passed between the outer tube and the inner tube; the water channel joint is installed on the side wall of the outer tube and has an interface for an external water supply system, and the water supply system is used to pass condensed water into the vacuum condenser through the water channel joint.

[0108] Among them, the structural principle of the vacuum condenser is similar to the glass condenser used to prepare distilled water in chemical experiments. It is used to cool the high-temperature gas sucked in by vacuum suction to prevent the high-temperature gas from transferring heat to the vacuum components and vacuum pumps.

[0109] In some embodiments, a glass bending device is also provided, including the glass forming device described above. Since the glass bending device adopts all embodiments of the glass forming device described above, it has all the beneficial effects of the glass forming device described above, which will not be described in detail here.
