Description

Technical Field

[0001] This application relates to the field of glass processing technology, and more specifically to a glass forming system. Background Technology

[0002] Glass parts can be processed and shaped into specific glass products to give them a particular appearance, a pleasant tactile feel, and scratch resistance. Typically, during the processing, after the glass part is placed in a mold, it undergoes several processing steps inside the mold, including preheating, shaping, and annealing. Throughout these steps, the glass part remains within the mold; the mold must participate in all processing steps, and inert gas must be supplied to protect the mold and extend its lifespan. Therefore, the glass processing involves a large number of molds, resulting in a significant consumption of inert gas for mold protection and higher processing costs. Utility Model Content

[0003] In order to at least solve the above-mentioned technical problems, the present application provides a glass forming system.

[0004] The forming system provided in this application is used for glass processing. The forming system includes a preheating device, a forming device, and an annealing device. A preheating device is used to preheat the initial glass component to a first temperature. The forming device includes a mounting plate, a first mold, a second mold, and a force-applying mechanism. The mounting plate has multiple stations, including a loading station, a forming station, and a unloading station. Each of the multiple stations corresponds to at least one pair of the first mold and the second mold. The first mold is mounted on the mounting plate and can rotate with the mounting plate to switch to different stations. The second mold corresponding to the loading station can move relative to the corresponding first mold to open or close to load the glass component. The second mold corresponding to the unloading station can move relative to the corresponding first mold to open to remove the glass component or close the mold. The force-applying mechanism is correspondingly arranged to the forming station and is used to drive the second mold corresponding to the forming station to form the glass component together with the first mold. Wherein: the first mold and the second mold corresponding to the loading station are used to jointly house and heat the preheated glass part to a second temperature, and after heating, at least the first mold rotates with the mounting plate to the forming station; the force application mechanism is also used to drive the second mold corresponding to the forming station to cooperate with the first mold to form the glass part at the second temperature; after forming, the mounting plate is also used to rotate, and at least drive the first mold on the forming station to rotate to the unloading station. The annealing device is used to receive the formed glass part taken from the first mold on the unloading station, and to perform annealing treatment on the formed glass part to obtain a glass product.

[0005] In the forming system of this application, a preheating device, a forming device, and an annealing device sequentially process an initial glass part to obtain a glass product. Specifically, the preheating device first preheats the initial glass part to a first temperature. The preheated glass part is placed in a first mold at the loading station and, after being heated to a second temperature, rotates with a mounting plate to the forming station for forming. After forming, the mounting plate rotates the formed glass part, which is placed in the first mold at the forming station, to the unloading station. The annealing device anneales the formed glass part removed from the first mold at the unloading station to obtain the glass product. Therefore, in the above glass processing and forming process, molds are used more often during the operation of the forming device, the number of molds used is relatively small, and the processing cost is low.

[0013] Glass parts can be processed and shaped into glass products of specific forms, giving them a particular appearance, good tactile feel, and scratch resistance. Typically, during the processing and forming process, after the glass part is placed in a mold, it undergoes several processing steps sequentially: preheating, forming, and annealing. Throughout these steps, the glass part remains within the mold; the mold must participate in all processing steps, and inert gas must be supplied to protect the mold and extend its lifespan. Therefore, the number of molds used in glass processing is relatively large, resulting in a significant consumption of inert gas for mold protection and high processing costs. To address this issue, this application provides a forming system 100 (e.g., Figure 1 and Figure 2 (As shown).

[0014] Please refer to Figures 1 to 5 The forming system 100 provided in this application is used for glass processing. The forming system 100 includes a preheating device 10, a forming device 30, and an annealing device 50.

[0015] The preheating device 10 is used to preheat the initial glass piece to a first temperature. The forming device 30 includes a mounting plate 31, a first mold 33, a second mold 34, and a force application mechanism 35.

[0016] The mounting plate 31 has multiple workstations, including a loading station 311, a forming station 313, and a unloading station 315. Each of the multiple workstations corresponds to at least one pair of first molds 33 and second molds 34. The first molds 33 are mounted on the mounting plate 31 and can rotate with the mounting plate 31 to switch to different workstations. The second mold 34 corresponding to the loading station 311 can move relative to the corresponding first mold 33 to open or close the mold to load the glass part. The second mold 34 corresponding to the unloading station 315 can move relative to the corresponding first mold 33 to open the mold to remove the glass part or close the mold. A force-applying mechanism 35 is correspondingly provided with the forming station 313. The force-applying mechanism 35 is used to drive the second mold 34 corresponding to the forming station 313 to form the glass part together with the first mold 33. Wherein: the first mold 33 and the second mold 34 corresponding to the loading station 311 are used to jointly house and heat the preheated glass part to a second temperature. After heating, at least the first mold 33 rotates with the mounting plate 31 to the forming station 313, where the second temperature is greater than the first temperature. The force application mechanism 35 is also used to drive the second mold 34 corresponding to the forming station 313 to cooperate with the first mold 33 to form the glass part at the second temperature. After forming, the mounting plate 31 is also used to rotate, and at least drive the first mold 33 on the forming station 313 to rotate to the unloading station 315. The annealing device 50 is used to receive the formed glass part taken from the first mold 33 on the unloading station 315 and perform annealing treatment on the formed glass part to obtain the glass product.

[0017] Specifically, in the above embodiments, the forming system 100 is an apparatus for performing a processing and forming step on a substrate to process the substrate into a specific shape. The substrate can be a semi-finished product or raw material in any step of machining, and the material of the substrate can be, but is not limited to, metal, glass, plastic, and rubber. The forming system 100 in this application is used to process glass parts so that the glass parts are processed and formed into glass products of a specific shape. At this time, the glass product processed and formed by the forming apparatus 30 has a specific appearance, good tactile feel, and scratch resistance.

[0018] Because glass is an amorphous solid at room temperature, it possesses high hardness but is also quite brittle. Therefore, the processing and shaping of glass parts must be carried out at a specific temperature. The preheating device 10 is used to preheat the initial glass part to a temperature close to its softening point, in order to facilitate subsequent processing and shaping steps. The softening point temperature of glass is the critical temperature at which glass transitions from a hard solid (elastic body) to a viscous liquid (viscous fluid). The softening point temperature is a specific temperature at which the glass begins to undergo measurable deformation or flow under its own gravity. The first temperature is a preset temperature close to the softening point temperature of the glass part. The first temperature can be any value within a temperature range close to the softening point temperature of the glass part, including a specific temperature range or a specific temperature value. When the temperature of the glass part is at the first temperature, the glass part approaches a viscous liquid state, the preheating purpose is achieved, and the glass part can be transferred to the next process. Therefore, the glass piece preheated to the first temperature can be transferred to the forming device 30 for subsequent processing steps, and since the temperature of the glass piece is already high, the heating time of the glass piece in the subsequent processing steps can be greatly shortened.

[0019] The forming device 30 is used to form a preheated glass part into a specific shape. The mounting plate 31 is a structure in the forming device 30 that can rotate and drive at least the first mold 33 to change position. The mounting plate drive 32 is a structure used to drive the mounting plate 31 to rotate. The mounting plate drive 32 can be, but is not limited to, a servo motor, a stepper motor, or a direct drive motor (DD motor). The mounting plate 31 is connected to the mounting plate drive 32 and rotates under the drive of the mounting plate drive 32 to drive the first mold 33 located on the mounting plate 31 to rotate. The mounting plate 31 has multiple stations, including a loading station 311 for receiving the preheated glass part, a forming station 313 for processing and forming the glass part, and a unloading station 315 where the glass part remains before being transferred to the annealing device 50 after forming. The first mold 33 is a mold used to hold the glass part. The second mold 34 is a mold used to cooperate with the first mold 33 to perform operations on the glass part. The shapes of the first mold 33 and the second mold 34 correspond to the specific form that the glass part will eventually be processed into. Each station is provided with at least one pair of first mold 33 and second mold 34, wherein at least the first mold 33 and the glass part it carries can rotate with the mounting plate 31 and switch to different stations to perform different processing and forming steps.

[0020] In the loading station 311 for receiving preheated glass parts, the second mold 34 corresponding to the loading station 311 can move relative to the corresponding first mold 33 to open or close, so as to load the preheated glass parts. In the unloading station 315 for holding the formed glass parts, the second mold 34 corresponding to the unloading station 315 can move relative to the corresponding first mold 33 to open, so as to remove the formed glass parts, and the second mold 34 corresponding to the unloading station 315 can move relative to the corresponding first mold 33 to close.

[0021] The force-applying mechanism 35 is a component used to drive the second mold 34 corresponding to the forming station 313. In the forming apparatus 30, the force-applying mechanism 35 is positioned corresponding to the forming station 313. The force-applying mechanism 35 can apply a force to the second mold 34 corresponding to the forming station 313, so that the second mold 34 changes the force between itself and the corresponding first mold 33 under the drive of the force-applying mechanism 35. At this time, the first mold 33 and the second mold 34 can form the glass piece housed therein through the aforementioned force. It should be noted that the force-applying mechanism 35 may or may not be connected to the second mold 34, as long as the force-applying mechanism 35 can apply a force to the second mold 34.

[0022] After the initial glass component is preheated to a first temperature, it is transferred to the forming device 30 for subsequent processing and forming steps. Specifically, the first mold 33 at the loading station 311 receives and places the preheated glass component, and the second mold 34 corresponding to the loading station 311 moves relative to the corresponding first mold 33 to jointly accommodate the preheated glass component. At this time, the first mold 33 and the second mold 34 corresponding to the loading station 311 are used together to heat the preheated glass component to a second temperature. The second temperature is a preset temperature suitable for processing and forming the glass component. The second temperature can be any value within the suitable temperature range for pressing the glass component, including a specific temperature range or a specific temperature value. It can be understood that the second temperature is greater than the first temperature. Compared to the temperature of the glass component at the first temperature, the glass component is softer and more suitable for processing and forming when its temperature is at the second temperature.

[0023] In some embodiments, the first mold 33 and the second mold 34 have a heating function to heat the glass part. In other embodiments, the first mold 33 and the second mold 34 do not have a heating function, and the first mold 33 and the second mold 34 are heated indirectly by external heating devices (the first action 37 and the second action 38 mentioned below).

[0024] Further, after the glass part is heated to the second temperature, the first mold 33 located at least at the loading station 311 and the glass part at the second temperature it carries are driven by the mounting plate 31 to the forming station 313 for processing and forming. At this time, the second mold 34 corresponding to the forming station 313 is driven by the force application mechanism 35 to close with the first mold 33 at the corresponding forming station 313 and apply force to the first mold 33. At this time, the second mold 34 corresponding to the forming station 313 and the first mold 33 at the forming station 313 form the glass part at the second temperature contained therein. The shape of the formed glass part is determined by the shape of the inner contour after the second mold 34 corresponding to the forming station 313 and the first mold 33 at the forming station 313 are closed. After the glass part is formed, the mounting plate 31 also drives the first mold 33 at least at the forming station 313 and the formed glass part located in the first mold 33 to rotate to the unloading station 315.

[0025] The annealing apparatus 50 is used to slowly cool the formed glass part to eliminate internal stress and improve its stability. After the formed glass part in the first mold 33 located at the unloading station 315 is transferred to the annealing apparatus 50, the first mold 33 at the unloading station 315 is unloaded, i.e., not carrying a glass part. After the mounting plate 31 rotates the first mold 33 at the unloading station 315 to the loading station 311, the first mold 33 can be used again to receive and carry the preheated glass part, thus achieving at least the cyclical use of the first mold 33. After annealing by the annealing apparatus 50, the formed glass part becomes a glass product with a specific shape. The glass product can be an intermediate product that continues to participate in or undergo other processing steps; the glass product can also be a final product that can be directly installed on an end product, and this application does not limit this. It is understood that in the process of the initial glass part being processed into a glass product through the above processing steps, the processing steps performed in the forming device 30 in most cases require the use of molds (second mold 34 and first mold 33). Therefore, the forming device 30 of this application uses a small number of molds.

[0026] In the forming system 100 of this application, the preheating device 10, the forming device 30, and the annealing device 50 sequentially process the initial glass part to obtain a glass product. Specifically, the preheating device 10 first preheats the initial glass part to a first temperature. The preheated glass part is placed in the first mold 33 on the loading station 311, and after being heated to a second temperature, it rotates with the mounting plate 31 to the forming station 313 for forming. After forming is completed, the mounting plate 31 drives the formed glass part placed in the first mold 33 on the forming station 313 to the unloading station 315. The annealing device 50 anneales the formed glass part removed from the first mold 33 on the unloading station 315 to obtain a glass product. Therefore, in the above glass processing and forming process, molds are used more often during the operation of the forming device 30, the number of molds used is small, and the processing cost is low.

[0027] The first embodiment of this application is described below.

[0028] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the molding apparatus 30 further includes a loading tray 36, which is spaced apart from the mounting tray 31, and a force-applying mechanism 35 is disposed on the loading tray 36. Each pair of first molds 33 and second molds 34 is disposed on the mounting tray 31, and in the mold-closed state, the second mold 34 is supported on the first mold 33. The force-applying mechanism 35 is used to generate a force on the second mold 34 to increase or decrease the force between the first mold 33 and the second mold 34.

[0029] Specifically, the loading tray 36 is a structure in the molding apparatus 30 used to load the force-applying mechanism 35 and other structures. The loading tray 36 is opposite to and spaced apart from the mounting tray 31, and the first mold 33 and the second mold 34 are both disposed in the space opposite to them. The force-applying mechanism 35 is connected to the loading tray 36 and is also opposite to the mounting tray 31. At least a portion of the force-applying mechanism 35 is movable relative to the loading tray 36. The connection between the force-applying mechanism 35 and the loading tray 36 can be a detachable connection or a non-detachable connection. Detachable connections include, but are not limited to, one or more combinations of methods such as screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of methods such as gluing, welding, and sintering. The following definitions of detachable and non-detachable connections will not be elaborated further.

[0030] The first mold 33 and the second mold 34, which cooperate with each other, form a pair. In this embodiment, each pair of cooperating first molds 33 and second molds 34 is disposed on the mounting plate 31. The first mold 33 is disposed on and connected to the mounting plate 31. The second mold 34, in the closed state, is supported on the first mold 33. In the open state, the second mold 34 is spaced apart from the corresponding first mold 33. It can be understood that during the molding process, the first mold 33 can always be closed with the second mold 34 and rotate together with the glass component housed therein, following the rotation of the mounting plate 31. The force-applying mechanism 35 can exert a force on the second mold 34. When the first mold 33 and the second mold 34 are closed and the second mold 34 is supported by the first mold 33, the force exerted by the force-applying mechanism 35 on the second mold 34 can change the force between the first mold 33 and the second mold 34, so as to increase or decrease the force between the first mold 33 and the second mold 34. This changes the force exerted by the first mold 33 and the second mold 34 on the glass mold housed between the first mold 33 and the second mold 34, so as to process and shape the glass mold.

[0031] Therefore, in the forming apparatus 30 of this application, the force application mechanism 35 provided on the loading plate 36 can change the force between the first mold 33 and the second mold 34 by applying force to the second mold 34, thereby realizing the processing and forming of the glass part. The stress state of the glass part during the processing and forming process is controllable, the processing and forming steps of the glass part are set more reasonably, the glass part can be efficiently formed into a specific shape while not easily broken, and the yield of the generated glass products is high.

[0032] Please refer to Figure 1 , Figure 3 and Figure 4In some embodiments, the molding system 100 has a processing sequence, and the molding station 313 includes a pressing station 3131 and a holding station 3133. In the rotational direction of the mounting plate 31 rotating from the loading station 311 to the unloading station 315, the pressing station 3131 and the holding station 3133 are arranged sequentially along the processing sequence. The force application mechanism 35 corresponding to the pressing station 3131 and the force application mechanism 35 corresponding to the holding station 3133 can each be independently controlled. Specifically: when the glass piece at the second temperature enters the pressing station 3131, the force application mechanism 35 corresponding to the pressing station 3131 applies a force to the second mold 34, causing the second mold 34 to abut against the corresponding first mold 33, thereby pressing the glass piece at the second temperature; after pressing is completed, the force application mechanism 35 corresponding to the pressing station 3131 is moved to separate from the second mold 34; the mounting plate 31 is also used to rotate, driving the first mold 33 and the second mold 34 on the pressing station 3131. The mold 34 rotates together to the pressure holding station 3133; the force applying mechanism 35 corresponding to the pressure holding station 3133 is used to apply force to the second mold 34 so that the second mold 34 holds against the corresponding first mold 33, thereby holding the pressed glass part under pressure; after the pressure holding is completed, the force applying mechanism 35 corresponding to the pressure holding station 3133 is used to move to separate from the second mold 34; the mounting plate 31 is also used to rotate and drive the first mold 33 and the second mold 34 on the pressure holding station 3133 to rotate to the unloading station 315.

[0033] Specifically, the processing sequence of the forming system 100 refers to the order in which the forming system 100 performs each processing step in the process of processing an initial glass part into a glass product. For example, the processing sequence could be: preheating, pressing, holding pressure, and annealing. The pressing station 3131 is a station for pressing the glass part to initially shape it and expel internal gases. The holding pressure station 3133 is a station for completing the product shaping and stress management (e.g., stress relief) under precisely controlled temperature and pressure. During the entire processing and forming process of an initial glass part in the forming apparatus 30, the glass part rotates from the loading station 311 to the unloading station 315 in the first mold 33 and the second mold 34, following the mounting plate 31. In this rotational direction, pressing and holding pressure are performed sequentially. Therefore, when the pressing station 3131 and the holding pressure station 3133 are arranged sequentially along the processing order, the pressing station 3131 is located upstream of the holding pressure station 3133. Thus, the glass part passes through the loading station 311, the pressing station 3131, the holding pressure station 3133, and the unloading station 315 in sequence. Furthermore, in order to perform the orderly processing and forming steps, the process by which the force-applying mechanism 35 corresponding to the pressing station 3131 applies force to the second mold 34, and the process by which the force-applying mechanism 35 corresponding to the holding pressure station 3133 applies force to the second mold 34, can be controlled independently without affecting each other.

[0034] After the glass component is heated to a second temperature, the first mold 33, the corresponding second mold 34, and the glass component at the second temperature, located at the loading station 311, are moved by the mounting plate 31 to the pressing station 3131 for pressing. At this time, the force application mechanism 35 corresponding to the pressing station 3131 applies a force to the second mold 34, causing the second mold 34 to abut against the first mold 33 at the corresponding pressing station 3131, increasing the force between the first mold 33 and the second mold 34 to a first pressing force. At this time, the second mold 34 corresponding to the pressing station 3131 and the first mold 33 at the pressing station 3131 press the glass component at the second temperature, and the shape of the pressed glass component is determined by the shape of the inner contour after the second mold 34 corresponding to the pressing station 3131 and the first mold 33 at the pressing station 3131 are closed. At least one of the second mold 34 and the first mold 33 heats the glass piece during the pressing process to keep it near a second temperature, thus preventing breakage during pressing. After pressing, the force-applying mechanism 35 moves relative to and separates from the second mold 34, reducing the force between the second mold 34 and the first mold 33. The mounting plate 31 also drives the first mold 33, the corresponding second mold 34, and the pressed glass piece housed within them on the pressing station 3131 to rotate to the pressure-holding station 3133.

[0035] On the one hand, because the glass part is extruded and formed under high speed and pressure at the pressing station 3131, its internal structure is forcibly twisted, generating huge internal stress. Therefore, after pressing, the pressed glass part needs a pressurized slow cooling environment, that is, it needs to be held under pressure at the holding pressure station 3133. Under the constraint of the holding pressure, the glass molecules have enough time to slowly rearrange and relax, thereby eliminating these internal stresses. On the other hand, the glass shrinks when it cools from a softened state. If the pressure is released and the glass is removed immediately after pressing, the shrinkage rate and degree of different parts of the product may be different, causing it to deviate from the ideal shape designed by the mold and deform such as warping and bending. The holding pressure (even if it is smaller than the pressing pressure) acts like a "mold shackle", which can tightly bind the glass part and force it to shrink according to the precision cavity of the mold, thereby obtaining a final product with accurate dimensions and stable shape. During the holding pressure process, the second mold 34 and the first mold 33 can always maintain a constant relative position or move relative to each other. This application places the pressing and holding pressure processes on pressing station 3131 and holding pressure station 3133 respectively, which can improve production efficiency. Specifically, the holding pressure process takes tens of seconds or even minutes, while the pressing process may only take a few seconds. This application adopts a multi-station design of mounting plate 31. While a glass part is under holding pressure for a long time at holding pressure station 3133, pressing station 3131 is already processing the next glass part. This realizes production line automation, avoids 100% waiting time in the molding system, and greatly improves production capacity.

[0036] After the glass component is pressed, the first mold 33, the corresponding second mold 34, and the pressed glass component housed therein, located at the pressing station 3131, are moved by the mounting plate 31 to the holding pressure station 3133 for holding pressure. At this time, the force application mechanism 35 corresponding to the holding pressure station 3133 applies a force to the second mold 34, causing the second mold 34 to abut against the first mold 33 at the corresponding holding pressure station 3133, increasing the force between the first mold 33 and the second mold 34 to the first holding pressure. At this time, the second mold 34 corresponding to the holding pressure station 3133 and the first mold 33 at the holding pressure station 3133 hold pressure on the pressed glass component housed therein, allowing the glass component to maintain its shape well after holding pressure. The relationship between the first holding pressure and the first pressing force depends on the material and shape of the glass component and the target shape of the resulting glass product, i.e., it is set according to specific circumstances. This application takes a thin-walled glass product after molding as an example. In this case, the first holding pressure is less than or equal to the first pressing force to avoid excessive deformation of the glass part caused by the holding pressure process. At least one of the second mold 34 and the first mold 33 heats the glass part during the holding pressure process to slowly reduce the temperature of the glass part and prevent the glass part from breaking during the holding pressure process. After the holding pressure of the glass part is completed, the force application mechanism 35 moves relative to the second mold 34 and separates from the second mold 34, and the force between the second mold 34 and the first mold 33 is reduced. The mounting plate 31 also drives the first mold 33, the corresponding second mold 34, and the glass part after holding pressure and housed in them on the holding pressure station 3133 to rotate to the unloading station 315.

[0037] Therefore, in the forming system 100 of this application, the forming station 313 includes a pressing station 3131 for pressing and a pressure holding station 3133 for holding pressure. The glass part at the second temperature is first pressed in the pressing station 3131 to initially form the glass part. After pressing, the glass part is driven by the mounting plate 31 to the pressure holding station 3133 for holding pressure, and at this time the temperature of the glass part initially decreases. The processing and forming steps of the glass part are set reasonably, and the glass part can be efficiently formed into a specific shape while not easily breaking, resulting in a high yield of the generated glass products.

[0038] Please refer to Figure 1 , Figures 3 to 5In some embodiments, the molding system 100 has a processing sequence, and the molding station 313 includes a first pressing station 31311, a second pressing station 31313, a first pressure holding station 31331, and a second pressure holding station 31333. In the rotational direction of the mounting plate 31 as it rotates from the loading station 311 to the unloading station 315, the first pressing station 31311, the second pressing station 31313, the first pressure holding station 31331, and the second pressure holding station 31333 are arranged sequentially along the processing sequence. The force application mechanism 35 corresponding to the first pressing station 31311, the second pressing station 31313, the first pressure holding station 31331, and the second pressure holding station 31333 can each be independently controlled. Specifically: when the glass piece at the second temperature enters the first pressing station 31311, the force-applying mechanism 35 corresponding to the first pressing station 31311 applies a force to the second mold 34, causing the second mold 34 to abut against the corresponding first mold 33, thereby performing the first pressing on the glass piece at the second temperature; after the first pressing is completed, the force-applying mechanism 35 corresponding to the first pressing station 31311 moves to separate from the second mold 34; the mounting plate 31 is also used to rotate and drive the first mold 33 on the first pressing station 31311. 3. The first mold 34 and the second mold 34 rotate together to the second pressing station 31313. The force application mechanism 35 corresponding to the second pressing station 31313 applies force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby performing a second pressing on the glass part after the first pressing. After the second pressing is completed, the force application mechanism 35 corresponding to the second pressing station 31313 moves to separate from the second mold 34. The mounting plate 31 is also used to rotate and drive the first mold 33 and the second mold 34 on the second pressing station 31313. 4. They rotate together to the first pressure holding station 31331; the force applying mechanism 35 corresponding to the first pressure holding station 31331 is used to apply force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby performing the first pressure holding on the second pressed glass part; after the first pressure holding is completed, the force applying mechanism 35 corresponding to the first pressure holding station 31331 is used to move to separate from the second mold 34; the mounting plate 31 is also used to rotate, and drive the first mold 33 and the second mold 34 on the first pressure holding station 31331 to rotate together to the first pressure holding station 31331. The second pressure holding station 31333; the force applying mechanism 35 corresponding to the second pressure holding station 31333 is used to apply force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby performing a second pressure holding on the glass part after the first pressure holding; after the second pressure holding is completed, the force applying mechanism 35 corresponding to the second pressure holding station 31333 is used to move to separate from the second mold 34; the mounting plate 31 is also used to rotate and drive the first mold 33 and the second mold 34 on the second pressure holding station 31333 to rotate together to the unloading station 315.

[0039] Specifically, the first pressing station 31311 is for preliminary pressing of the glass part to pre-form it and perform basic venting. The second pressing station 31313 is for further pressing of the glass part to achieve final shaping and fine venting. The first pressure holding station 31331 is for preliminary pressure holding of the pressed glass part to achieve preliminary stress relief at high temperature. The second pressure holding station 31333 is for further pressure holding of the glass part after the first pressure holding to achieve final shaping and complete elimination of residual stress. During the process of completing all the processing and forming steps in the forming device 30, the glass part rotates from the loading station 311 to the unloading station 315 in the first mold 33 and the second mold 34, following the mounting plate 31. In this rotation direction, the glass part passes through the loading station 311, the first pressing station 31311, the second pressing station 31313, the first pressure holding station 31331, the second pressure holding station 31333, and the unloading station 315 in sequence.

[0040] This application uses this embodiment as an example for illustration. Please refer to the following: Figure 1 and combined Figure 5 .exist Figure 5 In (a), the black cuboid represents the preheated glass part. The time when the preheated glass part is transferred to the first mold 33 on the loading station 311 is taken as the reference time. A is the first mold 33 and the second mold 34 corresponding to the loading station 311 at this time. B is the first mold 33 and the second mold 34 corresponding to the first pressing station 31311 at this time. C is the first mold 33 and the second mold 34 corresponding to the second pressing station 31313 at this time. D is the first mold 33 and the second mold 34 corresponding to the first holding station 31331 at this time. E is the first mold 33 and the second mold 34 corresponding to the second holding station 31333 at this time. F is the first mold 33 and the second mold 34 corresponding to the unloading station 315 at this time. Figure 5 (a) indicates that the first mold 33 and the second mold 34 on the loading station 311 are used to hold and heat the preheated glass piece and heat it to a second temperature.

[0041] After the glass component is heated to the second temperature, the first mold 33, the corresponding second mold 34, and the glass component at the second temperature, located at the loading station 311, are moved by the mounting plate 31 to the first pressing station 31311 for first pressing. Figure 5As shown in (b). At this time, the force-applying mechanism 35 corresponding to the first pressing station 31311 applies a force to the second mold 34, causing the second mold 34 to abut against the first mold 33 on the corresponding first pressing station 31311, and the force between the first mold 33 and the second mold 34 increases to a first sub-pressing force. At this time, the second mold 34 corresponding to the first pressing station 31311 and the first mold 33 on the first pressing station 31311 press the glass piece housed therein at the second temperature, and the shape of the glass piece after the first pressing is initially defined by the shape of the inner contour of the second mold 34 corresponding to the first pressing station 31311 and the first mold 33 on the first pressing station 31311 after mold closing. At least one of the second mold 34 and the first mold 33 heats the glass piece during the first pressing to keep the glass piece near the second temperature, so as to avoid the glass piece breaking during the first pressing. After the first pressing of the glass component is completed, the glass component is pre-formed and roughly degassed. Then, the force application mechanism 35 moves relative to the second mold 34 and separates from the second mold 34, reducing the force between the second mold 34 and the first mold 33. The mounting plate 31 also drives the first mold 33, the corresponding second mold 34, and the first pressed glass component housed in the first pressing station 31311 to rotate to the second pressing station 31313.

[0042] After the glass component is first pressed, the first mold 33, the corresponding second mold 34, and the first pressed glass component housed therein, located at the first pressing station 31311, are moved by the mounting plate 31 to the second pressing station 31313 for a second pressing. Figure 5As shown in (c). At this time, the force-applying mechanism 35 corresponding to the second pressing station 31313 applies a force to the second mold 34, causing the second mold 34 to abut against the first mold 33 on the corresponding second pressing station 31313, and the force between the first mold 33 and the second mold 34 increases to a second sub-pressing force. At this time, the second mold 34 corresponding to the second pressing station 31313 and the first mold 33 on the second pressing station 31313 press the glass piece housed therein, and the shape of the glass piece after the second pressing is ultimately determined by the shape of the inner contour of the second mold 34 corresponding to the second pressing station 31313 and the first mold 33 on the second pressing station 31313 after mold closing. At least one of the second mold 34 and the first mold 33 heats the glass piece during the second pressing to keep the glass piece near the second temperature, so as to avoid the glass piece from breaking during the second pressing. The relationship between the second pressing force and the first pressing force depends on the material and shape of the glass part and the target shape of the resulting glass product; that is, it is set according to the specific circumstances. This application takes a thin-walled glass product as an example. In this case, the second pressing force is less than or equal to the first pressing force to achieve final shaping and fine air removal of the glass part. After the second pressing of the glass part is completed, the force-applying mechanism 35 moves relative to the second mold 34 and separates from it, reducing the force between the second mold 34 and the first mold 33. The mounting plate 31 is also used to drive the first mold 33, the corresponding second mold 34, and the second-pressed glass part housed in the second pressing station 31313 to rotate to the first pressure-holding station 31331.

[0043] After the glass component is pressed a second time, the first mold 33, the corresponding second mold 34, and the second pressed glass component housed therein, located at the second pressing station 31313, are moved by the mounting plate 31 to the first pressure holding station 31331 for first pressure holding. Figure 5As shown in (d). At this time, the force-applying mechanism 35 corresponding to the first pressure-holding station 31331 applies a force to the second mold 34, so that the second mold 34 abuts against the first mold 33 on the corresponding first pressure-holding station 31331, and the force between the first mold 33 and the second mold 34 increases to the first sub-pressure holding force. At this time, the second mold 34 corresponding to the first pressure-holding station 31331 and the first mold 33 on the first pressure-holding station 31331 perform the first pressure holding on the second pressed glass piece housed therein. At least one of the second mold 34 and the first mold 33 heats the glass piece during the first pressure holding to prevent the glass piece from breaking due to deformation during the first pressure holding. The relationship between the second sub-pressure holding force and the first sub-pressure holding force depends on the material and shape of the glass piece and the target shape of the obtained glass product, that is, it is set according to the specific situation. Taking the formed glass product as a thin-walled shape as an example, the first sub-pressure holding force is less than or equal to the second sub-pressure holding force, so as to avoid over-forming of the glass piece while initially eliminating stress. After the first pressure holding of the glass component is completed, the stress on the glass component is initially eliminated. Then, the force application mechanism 35 moves relative to the second mold 34 and separates from the second mold 34, reducing the force between the second mold 34 and the first mold 33. The mounting plate 31 also drives the first mold 33, the corresponding second mold 34, and the glass component containing the first pressure holding at the first pressure holding station 31331 to rotate to the second pressure holding station 31333.

[0044] After the glass component is subjected to the first pressure holding, the first mold 33, the corresponding second mold 34, and the glass component housed therein, located at the first pressure holding station 31331, are moved by the mounting plate 31 to the second pressure holding station 31333 for the second pressure holding. Figure 5As shown in (e). At this time, the force-applying mechanism 35 corresponding to the second holding pressure station 31333 applies a force to the second mold 34, so that the second mold 34 abuts against the first mold 33 on the corresponding second holding pressure station 31333, and the force between the first mold 33 and the second mold 34 increases to the second sub-holding pressure. At this time, the second mold 34 corresponding to the second holding pressure station 31333 and the first mold 33 on the second holding pressure station 31333 perform a second holding pressure on the second pressed glass piece housed therein. At least one of the second mold 34 and the first mold 33 heats the glass piece during the second holding pressure, so that the temperature of the glass piece decreases slowly to avoid breakage of the glass piece during the second holding pressure process. The relationship between the second sub-holding pressure and the first sub-holding pressure depends on the material and shape of the glass piece and the target shape of the obtained glass product, that is, it is set according to the specific situation. Taking the formed glass product as a thin-walled shape as an example, the second sub-holding pressure is approximately equal to the first sub-holding pressure, so that the glass piece is finally shaped and residual stress is completely eliminated. After the second pressure holding of the glass component is completed, the temperature of the glass component decreases. Then, the force application mechanism 35 moves relative to and separates from the second mold 34, reducing the force between the second mold 34 and the first mold 33. The mounting plate 31 is also used to drive the first mold 33, the corresponding second mold 34, and the glass component housed in the second pressure holding station 31333 after the second pressure holding to rotate to the unloading station 315, as shown below. Figure 5 As shown in (f).

[0045] Therefore, in the forming system 100 of this application, the forming station 313 includes a first pressing station 31311 for initial pressing, a second pressing station 31313 for further pressing, a first holding station 31331 for initial holding pressure, and a second holding station 31333 for further holding pressure. The glass part at the second temperature is first pressed into shape at the first pressing station 31311 and the second pressing station 31313. After the second pressing, the glass part is sequentially driven by the mounting plate 31 to the first holding station 31331 and the second holding station 31333 to better eliminate internal stress, and at this time the temperature of the glass part initially decreases. The processing and forming steps of the glass part are set more reasonably, and the glass part can be efficiently formed into a specific shape while not easily breaking, resulting in a high yield of the generated glass products.

[0046] The above is at least part of the content of the first embodiment of this application. The second embodiment of this application is described below.

[0047] Please refer to Figure 1 , Figure 3 and Figure 4In some embodiments, the molding apparatus 30 further includes a loading tray 36, which is spaced apart from the mounting tray 31. A force-applying mechanism 35 is disposed on the loading tray 36 and connected to the second mold 34. The force-applying mechanism 35 applies a force to the second mold 34 to increase the force between the first mold 33 and the second mold 34, or to decrease the force between the first mold 33 and the second mold 34.

[0048] Specifically, the loading tray 36 is a structure in the molding apparatus 30 used to load components such as the force-applying mechanism 35. The loading tray 36 is opposite to and spaced apart from the mounting tray 31, and both the first mold 33 and the second mold 34 are disposed in the space opposite to them. The force-applying mechanism 35 is connected to the loading tray 36 and is also opposite to the mounting tray 31. The force-applying mechanism 35 is movably connected to the loading tray 36 so that at least a portion of the force-applying mechanism 35 can move relative to the loading tray 36. The connection between the force-applying mechanism 35 and the loading tray 36 can be either detachable or non-detachable.

[0049] The first mold 33 and the second mold 34 cooperate with each other as a pair. In this embodiment, in each pair of cooperating first molds 33 and second molds 34, the first mold 33 is disposed on and connected to the mounting plate 31, and the second mold 34 is connected to the force-applying mechanism 35 and can move up and down relative to the mounting plate 31 under the drive of the force-applying mechanism 35 to move closer to or away from the corresponding first mold 33. It can be understood that during the molding process, the force-applying mechanism 35 drives the second mold 34 to move, so that the first mold 33 and the second mold 34 are closed, and only the first mold 33 and the glass part it carries rotate with the mounting plate 31. The force-applying mechanism 35 exerts a force on the second mold 34 through its connection with the second mold 34, and the force exerted by the force-applying mechanism 35 on the second mold 34 can change the force between the first mold 33 and the second mold 34, so as to increase or decrease the force between the first mold 33 and the second mold 34, thereby changing the force exerted by the first mold 33 and the second mold 34 on the glass mold housed between the first mold 33 and the second mold 34, so as to process and shape the glass mold.

[0050] Therefore, in the forming apparatus 30 of this application, the force application mechanism 35 provided on the loading plate 36 can change the force between the first mold 33 and the second mold 34 by applying force to the second mold 34, thereby realizing the processing and forming of the glass part. The stress state of the glass part during the processing and forming process is controllable, the processing and forming steps of the glass part are set more reasonably, the glass part can be efficiently formed into a specific shape while not easily broken, and the yield of the generated glass products is high.

[0051] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the molding system 100 has a processing sequence, and the molding station 313 includes a pressing station 3131 and a holding station 3133. The pressing station 3131 and the holding station 3133 are arranged sequentially along the processing sequence in the rotation direction of the mounting plate 31 from the loading station 311 to the unloading station 315. The force application mechanism 35 corresponding to the pressing station 3131 and the force application mechanism 35 corresponding to the holding station 3133 can each be independently controlled. Specifically: when the glass piece at the second temperature enters the pressing station 3131, the force application mechanism 35 corresponding to the pressing station 3131 applies a force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby pressing the glass piece at the second temperature; after pressing is completed, the force application mechanism 35 corresponding to the pressing station 3131 drives the second mold 34 away from and disengages from the corresponding first mold 33; the mounting plate 31 is also used to rotate and drive the first mold 33 on the pressing station 3131... The mold 33 rotates to the pressure holding station 3133; the force applying mechanism 35 corresponding to the pressure holding station 3133 is used to apply force to the second mold 34 so that the second mold 34 holds against the corresponding first mold 33, thereby holding the pressed glass part under pressure; after the pressure holding is completed, the force applying mechanism 35 corresponding to the pressure holding station 3133 is used to drive the second mold 34 away from and disengage from the corresponding first mold 33; the mounting plate 31 is also used to rotate and drive the first mold 33 on the pressure holding station 3133 to rotate to the unloading station 315.

[0052] The processing sequence of the forming system 100 refers to the order in which the forming system 100 performs each processing step in the process of processing an initial glass part into a glass product. For example, the processing sequence could be: preheating, pressing, holding pressure, and annealing. The pressing station 3131 is the station for pressing the glass part to initially shape it and expel internal gases. The holding pressure station 3133 is the station for completing the product shaping and stress management under precisely controlled temperature and pressure. During the entire processing and forming process of an initial glass part in the forming apparatus 30, the glass part rotates from the loading station 311 to the unloading station 315 in the first mold 33 along with the mounting plate 31. In this rotational direction, pressing and holding pressure are performed sequentially. Therefore, when the pressing station 3131 and the holding pressure station 3133 are arranged sequentially along the processing order, the pressing station 3131 is located upstream of the holding pressure station 3133. Thus, the glass part passes through the loading station 311, the pressing station 3131, the holding pressure station 3133, and the unloading station 315 in sequence. Furthermore, in order to perform the orderly processing and forming steps, the process by which the force-applying mechanism 35 corresponding to the pressing station 3131 applies force to the second mold 34 and the process by which the force-applying mechanism 35 corresponding to the holding pressure station 3133 applies force to the second mold 34 can be independently controlled without affecting each other.

[0053] After the glass component is heated to a second temperature, the first mold 33 located at the loading station 311 and the glass component at the second temperature are moved by the mounting plate 31 to the pressing station 3131 for pressing. At this time, the force application mechanism 35 corresponding to the pressing station 3131 applies a force to the second mold 34, causing the second mold 34 to come into contact with the first mold 33 at the corresponding pressing station 3131, increasing the force between the first mold 33 and the second mold 34 to a first pressing force. At this time, the second mold 34 corresponding to the pressing station 3131 and the first mold 33 at the pressing station 3131 press the glass component at the second temperature contained therein. The shape of the pressed glass component is determined by the shape of the inner contour after the second mold 34 corresponding to the pressing station 3131 and the first mold 33 at the pressing station 3131 are closed. At least one of the second mold 34 and the first mold 33 heats the glass component during the pressing process to keep the glass component near the second temperature, thereby preventing the glass component from breaking during the pressing process. After the glass piece is pressed, the force application mechanism 35 drives the second mold 34 to move and separate from the first mold 33. The mounting plate 31 also drives the first mold 33 on the pressing station 3131 and the pressed glass piece located in the first mold 33 to rotate to the pressure holding station 3133.

[0054] After the glass component is pressed, the first mold 33 located at the pressing station 3131 and the pressed glass component it carries are moved by the mounting plate 31 to the holding pressure station 3133 for holding pressure. At this time, the force application mechanism 35 corresponding to the holding pressure station 3133 applies a force to the second mold 34, causing the second mold 34 to come into contact with the first mold 33 at the corresponding holding pressure station 3133, increasing the force between the first mold 33 and the second mold 34 to the first holding pressure. At this time, the second mold 34 corresponding to the holding pressure station 3133 and the first mold 33 at the holding pressure station 3133 hold pressure on the pressed glass component housed therein, and the glass component can maintain its shape well after holding pressure. The relationship between the first holding pressure and the first pressing force depends on the material and shape of the glass component and the target shape of the resulting glass product, i.e., it is set according to the specific situation. This application takes a thin-walled glass product after forming as an example, in which case the first holding pressure is less than or equal to the first pressing force to avoid excessive deformation of the glass component caused by the holding pressure process. At least one of the second mold 34 and the first mold 33 heats the glass component during the pressure holding process to slowly lower its temperature and prevent breakage. After the pressure holding of the glass component is completed, the force application mechanism 35 moves the second mold 34 and separates it from the first mold 33. The mounting plate 31 also drives the first mold 33 on the pressure holding station 3133 and the pressure-held glass component located in the first mold 33 to rotate to the unloading station 315.

[0055] Therefore, in the forming system 100 of this application, the forming station 313 includes a pressing station 3131 for pressing and a pressure holding station 3133 for holding pressure. The glass part at the second temperature is first pressed in the pressing station 3131 to initially form the glass part. After pressing, the glass part is driven by the mounting plate 31 to the pressure holding station 3133 for holding pressure, and at this time the temperature of the glass part initially decreases. The processing and forming steps of the glass part are set reasonably, and the glass part can be efficiently formed into a specific shape while not easily breaking, resulting in a high yield of the generated glass products.

[0056] Please refer to Figure 1 , Figures 3 to 5In some embodiments, the molding system 100 has a processing sequence, and the molding station 313 includes a first pressing station 31311, a second pressing station 31313, a first holding pressure station 31331, and a second holding pressure station 31333. In the rotational direction in which the first mold 33 follows the mounting plate 31 from the loading station 311 to the unloading station 315, the first pressing station 31311, the second pressing station 31313, the first holding pressure station 31331, and the second holding pressure station 31333 are arranged sequentially along the processing sequence. The force application mechanism 35 corresponding to the first pressing station 31311, the second pressing station 31313, the first holding pressure station 31331, and the second holding pressure station 31333 can each be independently controlled. Specifically: when the glass piece at the second temperature enters the first pressing station 31311, the force-applying mechanism 35 corresponding to the first pressing station 31311 applies a force to the second mold 34, causing the second mold 34 to abut against the corresponding first mold 33, thereby performing the first pressing on the glass piece at the second temperature; after the first pressing is completed, the force-applying mechanism 35 corresponding to the first pressing station 31311 drives the second mold 34 away from and disengages from the corresponding first mold 33; the mounting plate 31 is also used to rotate and drive the first pressing station 31 The first mold 33 on 311 rotates to the second pressing station 31313; the force-applying mechanism 35 corresponding to the second pressing station 31313 applies force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby performing a second pressing on the glass part after the first pressing; after the second pressing is completed, the force-applying mechanism 35 corresponding to the second pressing station 31313 drives the second mold 34 away from and disengages from the corresponding first mold 33; the mounting plate 31 is also used to rotate and drive the first mold 33 on the second pressing station 31313 to rotate. A mold 33 rotates to the first pressure holding station 31331; the force applying mechanism 35 corresponding to the first pressure holding station 31331 applies force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby performing the first pressure holding on the second pressed glass piece; after the first pressure holding is completed, the force applying mechanism 35 corresponding to the first pressure holding station 31331 drives the second mold 34 away from and disengages from the corresponding first mold 33; the mounting plate 31 is also used to rotate and drive the first mold 33 on the first pressure holding station 31331. Rotate to the second pressure holding station 31333; the force applying mechanism 35 corresponding to the second pressure holding station 31333 is used to apply force to the second mold 34 so that the second mold 34 abuts against the corresponding first mold 33, thereby performing a second pressure holding on the glass part after the first pressure holding; after the second pressure holding is completed, the force applying mechanism 35 corresponding to the second pressure holding station 31333 is used to drive the second mold 34 away from and disengage from the corresponding first mold 33; the mounting plate 31 is also used to rotate and drive the first mold 33 on the second pressure holding station 31333 to rotate to unload.

[0057] Specifically, the first pressing station 31311 is for preliminary pressing of the glass part to pre-form it and perform basic venting. The second pressing station 31313 is for further pressing of the glass part to achieve final shaping and fine venting. The first pressure holding station 31331 is for preliminary pressure holding of the pressed glass part to achieve preliminary stress relief at high temperature. The second pressure holding station 31333 is for further pressure holding of the glass part after the first pressure holding to achieve final shaping and complete elimination of residual stress. During the process of completing all the processing and forming steps in the forming device 30, the glass part rotates from the loading station 311 to the unloading station 315 in the first mold 33 and the second mold 34, following the mounting plate 31. In this rotation direction, the glass part passes through the loading station 311, the first pressing station 31311, the second pressing station 31313, the first pressure holding station 31331, the second pressure holding station 31333, and the unloading station 315 in sequence.

[0058] This application uses this embodiment as an example for illustration. Please refer to the following: Figure 1 and combined Figure 5 .exist Figure 5 In (a), the black cuboid represents the preheated glass part. The reference time is the moment when the preheated glass part is transferred to the first mold 33 on the loading station 311. A is the first mold 33 corresponding to the loading station 311 at this moment, B is the first mold 33 corresponding to the first pressing station 31311 at this moment, C is the first mold 33 corresponding to the second pressing station 31313 at this moment, D is the first mold 33 corresponding to the first holding station 31331 at this moment, E is the first mold 33 corresponding to the second holding station 31333 at this moment, and F is the first mold 33 corresponding to the unloading station 315 at this moment. Figure 5 (a) indicates that the first mold 33 and the second mold 34 on the loading station 311 are used to hold and heat the preheated glass piece and heat it to a second temperature.

[0059] After the glass component is heated to the second temperature, the first mold 33 located at the loading station 311 and the glass component under the second temperature are driven by the mounting plate 31 to the first pressing station 31311 for the first pressing, as follows. Figure 5As shown in (b). At this time, the force-applying mechanism 35 corresponding to the first pressing station 31311 applies a force to the second mold 34, causing the second mold 34 to come into contact with the first mold 33 on the corresponding first pressing station 31311, and the force between the first mold 33 and the second mold 34 increases to the first sub-pressing force. At this time, the second mold 34 corresponding to the first pressing station 31311 and the first mold 33 on the first pressing station 31311 press the glass piece contained therein, and the shape of the glass piece after the first pressing is initially defined by the shape of the inner contour of the second mold 34 corresponding to the first pressing station 31311 and the first mold 33 on the first pressing station 31311 after mold closing. At least one of the second mold 34 and the first mold 33 heats the glass piece during the first pressing to keep the glass piece near the second temperature to avoid breakage of the glass piece during the first pressing. After the first pressing of the glass component is completed, the glass component is pre-formed and roughly degassed by the initial pressing. Then, the force application mechanism 35 drives the second mold 34 to move and separate from the first mold 33. The mounting plate 31 also drives the first mold 33 on the first pressing station 31311 and the first pressed glass component located in the first mold 33 to rotate to the second pressing station 31313.

[0060] After the glass component is first pressed, the first mold 33 located at the first pressing station 31311 and the first pressed glass component it carries are moved by the mounting plate 31 to the second pressing station 31313 for a second pressing. Figure 5As shown in (c). At this time, the force-applying mechanism 35 corresponding to the second pressing station 31313 applies a force to the second mold 34, causing the second mold 34 to come into contact with the first mold 33 on the corresponding second pressing station 31313. The force between the first mold 33 and the second mold 34 increases to a second pressing force. At this time, the second mold 34 corresponding to the second pressing station 31313 and the first mold 33 on the second pressing station 31313 press the glass piece housed therein at the second temperature. The shape of the glass piece after the second pressing is ultimately determined by the shape of the inner contour of the second mold 34 corresponding to the second pressing station 31313 and the first mold 33 on the second pressing station 31313 after mold closing. At least one of the second mold 34 and the first mold 33 heats the glass piece during the second pressing to keep the glass piece near the second temperature, so as to avoid the glass piece breaking during the second pressing. The relationship between the second pressing force and the first pressing force depends on the material and shape of the glass part and the target shape of the resulting glass product; that is, it is set according to the specific circumstances. This application takes a thin-walled glass product as an example, where the second pressing force is less than or equal to the first pressing force to achieve final shaping and fine air removal of the glass part. After the second pressing of the glass part is completed, the force-applying mechanism 35 drives the second mold 34 to move and separate from the first mold 33. The mounting plate 31 is also used to drive the first mold 33 on the second pressing station 31313 and the second-pressed glass part located in the first mold 33 to rotate to the first pressure-holding station 31331.

[0061] After the glass component is pressed a second time, the first mold 33 located at the second pressing station 31313 and the second pressed glass component it carries are moved by the mounting plate 31 to the first pressure holding station 31331 for first pressure holding. Figure 5As shown in (d). At this time, the force-applying mechanism 35 corresponding to the first pressure-holding station 31331 applies a force to the second mold 34, causing the second mold 34 to come into contact with the first mold 33 on the corresponding first pressure-holding station 31331, and the force between the first mold 33 and the second mold 34 increases to the first sub-pressure holding force. At this time, the second mold 34 corresponding to the first pressure-holding station 31331 and the first mold 33 on the first pressure-holding station 31331 perform the first pressure holding on the second pressed glass piece housed therein. At least one of the second mold 34 and the first mold 33 heats the glass piece during the first pressure holding to prevent the glass piece from breaking due to deformation during the first pressure holding. The relationship between the second sub-pressure holding force and the first sub-pressure holding force depends on the material and shape of the glass piece and the target shape of the obtained glass product, i.e., it is set according to the specific situation. This application takes a thin-walled glass product after molding as an example. At this time, the first sub-pressure holding force is less than or equal to the second sub-pressure holding force to avoid over-molding of the glass piece while initially eliminating stress. After the first pressure holding of the glass component is completed, the stress on the glass component is initially eliminated. Then, the force application mechanism 35 drives the second mold 34 to move and separate from the first mold 33. The mounting plate 31 also drives the first mold 33 on the first pressure holding station 31331 and the glass component located in the first mold 33 after the first pressure holding to rotate to the second pressure holding station 31333.

[0062] After the glass component is subjected to the first pressure holding, the first mold 33 located at the first pressure holding station 31331 and the glass component it carries after the first pressure holding are moved by the mounting plate 31 to the second pressure holding station 31333 for the second pressure holding. Figure 5As shown in (e). At this time, the force-applying mechanism 35 corresponding to the second holding pressure station 31333 applies a force to the second mold 34, causing the second mold 34 to come into contact with the first mold 33 on the corresponding second holding pressure station 31333. The force between the first mold 33 and the second mold 34 increases to the second sub-holding pressure. At this time, the second mold 34 corresponding to the second holding pressure station 31333 and the first mold 33 on the second holding pressure station 31333 perform a second holding pressure on the second pressed glass piece housed therein. At least one of the second mold 34 and the first mold 33 heats the glass piece during the second holding pressure, so that the temperature of the glass piece decreases slowly to avoid breakage of the glass piece during the second holding pressure process. The relationship between the second sub-holding pressure and the first sub-holding pressure depends on the material and shape of the glass piece and the target shape of the obtained glass product, i.e., it is set according to the specific situation. Taking the formed glass product as a thin-walled shape as an example, the second sub-holding pressure is approximately equal to the first sub-holding pressure, so that the glass piece is finally shaped and residual stress is completely eliminated. After the second pressure holding of the glass component is completed, the temperature of the glass component decreases. Then, the force application mechanism 35 drives the second mold 34 to move and separate from the first mold 33. The mounting plate 31 is also used to drive the first mold 33 on the second pressure holding station 31333 and the second-pressure-held glass component located in the first mold 33 to rotate to the unloading station 315, such as... Figure 5 As shown in (f).

[0063] Therefore, in the forming system 100 of this application, the forming station 313 includes a first pressing station 31311 for initial pressing, a second pressing station 31313 for further pressing, a first holding station 31331 for initial holding pressure, and a second holding station 31333 for further holding pressure. The glass part at the second temperature is first pressed into shape at the first pressing station 31311 and the second pressing station 31313. After the second pressing, the glass part is sequentially driven by the mounting plate 31 to the first holding station 31331 and the second holding station 31333 to better eliminate internal stress, and at this time the temperature of the glass part initially decreases. The processing and forming steps of the glass part are set more reasonably, and the glass part can be efficiently formed into a specific shape while not easily breaking, resulting in a high yield of the generated glass products.

[0064] The above is at least a part of the content of the second embodiment of this application.

[0065] Please refer to Figure 1 , Figures 3 to 5In some embodiments, the deformation of the glass component at the second temperature caused by the first pressing is greater than the deformation of the glass component after the first pressing caused by the second pressing. Specifically, since the first pressing station 31311 is used to initially press the glass component to preliminary shaping, and the second pressing station 31313 is used to further press the glass component to final shaping, the pressing process of the glass component is more reasonable when the deformation of the glass component at the second temperature caused by the first pressing is greater than the deformation of the glass component after the first pressing caused by the second pressing. The glass component is already close to the final required specific shape after the first pressing, and the second pressing ensures that the glass component is accurately pressed to the specific shape. Therefore, the glass component after the (second) pressing is pressed to the specific shape more accurately, resulting in better quality and a higher yield rate for the subsequently produced glass products.

[0066] It is understood that in order to ensure the smooth and undamaged formation (pressing, pressure holding) of the glass parts, the first mold 33 and / or the second mold 34 need to heat the glass parts at each forming station 313. Here, we will use the temperature of the first mold 33 when at least the first mold 33 heats the glass parts as an example. If the second mold 34 also heats the glass parts, the temperature of the second mold 34 is as follows. It should be noted that the temperature of the second mold 34 at each station can be the same as or different from the temperature of the first mold 33. This application does not impose any restrictions on this. However, the temperature of the second mold 34 cannot produce technical effects that contradict those of the first mold 33. For example, if the first mold 33 has a sixth temperature at the second pressure holding station 31333, and this sixth temperature is greater than or equal to the annealing point temperature of the glass parts but less than the softening point temperature of the glass parts, the temperature of the second mold 34 cannot deviate from the technical effects achieved by the temperature range of the first mold 33. In this case, the second mold 34 can also adopt the aforementioned temperature range, or adopt other temperature ranges that do not affect the technical effects achieved by the temperature range of the first mold 33.

[0067] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first mold 33 has a third temperature when it is at the first pressing station 31311. The third temperature is greater than or equal to the softening point temperature of the glass and less than the crystallization temperature of the glass.

[0068] Specifically, when the glass part at the second temperature is moved from the first mold 33 at the loading station 311 to the first pressing station 31311, the first mold 33 needs to maintain heating on the glass part it carries to ensure that the glass part can be pressed without breaking. The third temperature is the temperature value of the first mold 33 at the first pressing station 31311. The third temperature can be any value within the range of mold temperatures corresponding to the suitable pressing temperature of the glass part, including a specific temperature range or a specific temperature value. Since the glass part is in direct contact with the first mold 33 and heat transfer occurs, the temperature of the first mold 33 will directly affect the temperature of the glass part, and thus affect the effect of the first pressing.

[0069] When the third temperature is greater than or equal to the softening point of the glass, the glass can be heated by the first mold 33 and maintained in a relatively soft state to ensure that the first pressing can proceed normally. At the same time, the third temperature is lower than the crystallization temperature of the glass to avoid overheating of the glass and crystallization, which could lead to at least one of the following problems: reduced transparency, reduced mechanical strength, or decreased thermal stability.

[0070] Therefore, when the third temperature is greater than or equal to the softening point temperature of the glass and less than the crystallization temperature of the glass, the temperature of the glass in the first pressing is reasonably controlled. The glass can be pressed smoothly without crystallization and becoming a defective product, resulting in a high yield of the generated glass products.

[0071] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first mold 33 has a fourth temperature when it is at the second pressing station 31313. The fourth temperature is greater than or equal to the softening point temperature of the glass and less than the crystallization temperature of the glass.

[0072] Specifically, when the first pressed glass piece is moved from the first mold 33 at the first pressing station 31311 to the second pressing station 31313, the first mold 33 needs to maintain heating on the glass piece it carries to ensure that the glass piece can be pressed without breaking. The fourth temperature is the temperature value of the first mold 33 when it is at the second pressing station 31313. The fourth temperature can be any value within the range of mold temperatures corresponding to the suitable pressing temperature of the glass piece. Since the glass piece is in direct contact with the first mold 33 and heat transfer occurs, the temperature of the first mold 33 will directly affect the temperature of the glass piece, and thus affect the effect of the second pressing.

[0073] When the fourth temperature is greater than or equal to the softening point of the glass, the glass can be heated by the first mold 33 and maintained in a relatively soft state to ensure that the second pressing can proceed normally. At the same time, the fourth temperature is lower than the crystallization temperature of the glass to avoid overheating of the glass and crystallization, which could lead to at least one of the following problems: reduced transparency, reduced mechanical strength, or decreased thermal stability.

[0074] Therefore, when the fourth temperature is greater than or equal to the softening point temperature of the glass and less than the crystallization temperature of the glass, the temperature control of the glass in the second pressing is relatively reasonable. The glass can be pressed smoothly without crystallization and becoming a defective product, resulting in a high yield of the generated glass products.

[0075] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first mold 33 has a fifth temperature when it is in the first holding pressure station 31331. The fifth temperature is greater than or equal to the softening point temperature of the glass and less than the crystallization temperature of the glass.

[0076] Specifically, when the glass part after the second pressing is moved from the first mold 33 on the second pressing station 31313 to the first pressure holding station 31331, the first mold 33 needs to maintain heating on the glass part it carries so that the glass part can deform and maintain a specific shape. The fifth temperature is the temperature value of the first mold 33 when it is on the first pressure holding station 31331. The fifth temperature can be any value within the range of mold temperatures corresponding to the suitable pressure holding temperature of the glass part. Since the glass part is in direct contact with the first mold 33 and heat transfer occurs, the temperature of the first mold 33 will directly affect the temperature of the glass part, and thus affect the effect of the first pressure holding.

[0077] When the fifth temperature is greater than or equal to the softening point of the glass, the glass can be heated by the first mold 33 and maintained in a relatively soft state to ensure that the first pressure holding can proceed normally. At the same time, the fifth temperature is lower than the crystallization temperature of the glass to avoid the glass being overheated and crystallizing, which could lead to at least one of the following problems: reduced transparency, reduced mechanical strength, or decreased thermal stability.

[0078] Therefore, when the fifth temperature is greater than or equal to the softening point temperature of the glass and less than the crystallization temperature of the glass, the temperature of the glass in the first holding pressure is reasonably controlled. The glass can smoothly undergo the first holding pressure without crystallization and becoming a defective product, resulting in a high yield of the generated glass products.

[0079] Please refer to Figure 1 , Figures 3 to 5In some embodiments, the first mold 33 has a sixth temperature when it is in the second pressure holding station 31333. The sixth temperature is greater than or equal to the annealing point temperature of the glass and less than the softening point temperature of the glass.

[0080] Specifically, when the glass component under first pressure is moved from the first mold 33 at the first pressure holding station 31331 to the second pressure holding station 31333, the first mold 33 needs to maintain heating on the glass component it carries so that the glass component can cool down slowly and maintain a specific shape, and the subsequent annealing process can proceed well. The sixth temperature is the temperature value of the first mold 33 when it is at the second pressure holding station 31333. The sixth temperature can be any value within the range of mold temperatures corresponding to the temperature at which the glass component can cool down slowly. Since the glass component is in direct contact with the first mold 33 and heat transfer occurs, the temperature of the first mold 33 will directly affect the temperature of the glass component, and thus affect the effect of the second pressure holding.

[0081] The annealing point temperature of glass is a specific temperature at which internal stress can be effectively eliminated within minutes. When the sixth temperature is greater than or equal to the annealing point temperature of the glass, the cooling process proceeds more slowly, preventing the glass from breaking due to sudden cooling, and allowing the second holding pressure to proceed normally. Simultaneously, the sixth temperature is lower than the softening point temperature of the glass to prevent deformation that could cause it to deviate from its intended shape and become a defective product.

[0082] Therefore, when the sixth temperature is greater than or equal to the annealing temperature of the glass part, but less than the softening temperature of the glass part, the temperature control of the glass part in the second holding pressure is relatively reasonable. The glass part can smoothly undergo the second holding pressure without deforming and becoming a defective product, resulting in a high yield of the generated glass products.

[0083] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first mold 33 has a seventh temperature when it is at the unloading station 315. The seventh temperature is greater than or equal to the annealing point temperature of the glass and less than the softening point temperature of the glass.

[0084] Specifically, when the glass part under second pressure is moved from the first mold 33 at the second pressure station 31333 to the unloading station 315, the first mold 33 needs to maintain heating on the glass part it carries so that the glass part can cool down slowly, allowing the formed glass part to be smoothly transferred to the annealing device 50. The seventh temperature is the temperature value of the first mold 33 when it is at the unloading station 315. The seventh temperature can be any value within the range of mold temperatures corresponding to the temperature at which the glass part can cool down slowly. Since the glass part is in direct contact with the first mold 33 and heat transfer occurs, the temperature of the first mold 33 will directly affect the temperature of the glass part.

[0085] When the seventh temperature is greater than or equal to the annealing point temperature of the glass, the cooling process of the glass proceeds more slowly, preventing the glass from breaking due to sudden cooling. At the same time, the seventh temperature is lower than the softening point temperature of the glass to prevent the glass from deforming and deviating from its specific shape during the transfer to the annealing apparatus 50, thus avoiding it becoming a defective product.

[0086] Therefore, when the seventh temperature is greater than or equal to the annealing point temperature of the glass part, but less than the softening point temperature of the glass part, the temperature of the glass part at the unloading station 315 is reasonably controlled, and the glass part can be smoothly transferred to the annealing device 50 without deformation and becoming a defective product, resulting in a high yield of the generated glass products.

[0087] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first temperature is lower than the softening point temperature of the glass, and the second temperature is greater than or equal to the softening point temperature and lower than the crystallization temperature of the glass.

[0088] Specifically, in the above embodiment, the initial glass piece is sequentially heated to a first temperature and a second temperature at the preheating device 10 and the loading station 311, with the first temperature being lower than the second temperature. Since the first temperature is lower than the softening point of the glass piece, it is preheated but has not yet softened. Therefore, the preheated glass piece will not deform and break or become a defective product during its transfer to the forming device 30, allowing subsequent processing steps to proceed normally. Furthermore, because the glass piece is already at a relatively high temperature, the heating time for the glass piece in subsequent processing steps can be significantly shortened.

[0089] The preheated glass part is transferred from the preheating device 10 to the first mold 33 on the loading station 311 for subsequent forming steps. Furthermore, the crystallization temperature of glass is the temperature at which glass begins to precipitate crystals from its amorphous solid state. Glass crystallization leads to a series of problems such as reduced transparency, reduced mechanical strength, and decreased thermal stability. The first mold 33 and the second mold 34 need to heat the preheated glass part to a second temperature. When the second temperature is greater than or equal to the softening point temperature, the glass part is heated by the first mold 33 and the second mold 34 until it softens, at which point the glass can be processed and formed. Simultaneously, the second temperature is lower than the crystallization temperature of the glass part to avoid at least one of the problems of reduced transparency, reduced mechanical strength, and decreased thermal stability caused by glass crystallization.

[0090] Therefore, when the first temperature is lower than the softening point of the glass and the second temperature is greater than or equal to the softening point but lower than the crystallization temperature, the heating process of the glass is more reasonable. The initial glass is heated to a high temperature by the preheating device 10 without softening. The preheated glass does not deform during transfer to the forming device 30, allowing subsequent processing steps to proceed normally, and effectively shortening the heating time in these steps. The preheated glass is further heated to the second temperature so that it can undergo the forming process without crystallization, thus avoiding becoming a defective product. In summary, the forming device 30's settings for the glass forming steps are reasonable, resulting in a high yield rate for the generated glass products.

[0091] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the molding apparatus 30 further includes a first actuating element 37 and a second actuating element 38. The first actuating element 37 is disposed on at least one of the mounting plate 31 and the first mold 33, with each first mold 33 corresponding to one first actuating element 37. The first actuating element 37 is used to heat the corresponding first mold 33. Each second mold 34 is correspondingly provided with one second actuating element 38, which is used to heat the corresponding second mold 34. At least one of the second mold 34 and the first mold 33 is a graphite mold, a metal mold, or a ceramic mold.

[0092] Specifically, the first actuating element 37 is a structure used to control the temperature of the first mold 33. The number and arrangement of the first actuating elements 37 are the same as the number and arrangement of the first molds 33, so that each first actuating element 37 corresponds to one first mold 33 and controls the temperature of the first mold 33, thereby heating the first mold 33 and heating the glass piece. The second actuating element 38 is a structure used to control the temperature of the second mold 34. The number and arrangement of the second actuating elements 38 are the same as the number and arrangement of the second molds 34, so that each second actuating element 38 corresponds to one second mold 34 and controls the temperature of the second mold 34, thereby heating the second mold 34 and heating the glass piece.

[0093] At least one of the second mold 34 and the first mold 33 is a graphite mold, a metal mold or a ceramic mold. Because graphite has many advantages such as high temperature resistance, self-lubrication (easy demolding), uniform heat conduction, easy processing and chemical inertness, graphite molds, metal molds or ceramic molds can better meet the requirements of high temperature processing and forming of glass parts. At this time, the glass products produced are of high quality and have a high yield rate.

[0094] The forming apparatus 30 of this application controls the temperature of the first mold 33 through the first action 37 and controls the temperature of the second mold 34 through the second action 38, so that the forming apparatus 30 can accurately control the temperature of the glass part through the second mold 34 and the first mold 33, the glass part processing and forming steps can be carried out in an orderly and normal manner, and the yield of the generated glass products is high.

[0095] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first action 37 and the second action 38 are used to generate an alternating magnetic field by passing electricity, so that eddy currents are formed inside the first mold 33 and the second mold 34 to generate heat and raise the temperature.

[0096] Specifically, the first actuating element 37 generates an alternating magnetic field when energized, causing eddy currents to form inside the corresponding first mold 33, which then heats up under the influence of these eddy currents. The second actuating element 38 generates an alternating magnetic field when energized, causing eddy currents to form inside the corresponding second mold 34, which then heats up under the influence of these eddy currents. At this time, both the first mold 33 and the second mold 34 heat up rapidly, allowing both sides of the glass piece to be heated quickly and evenly.

[0097] At this time, the second action element 38 and the first action element 37 can be magnetic induction coils. The current conducted in the second action element 38 and the first action element 37 can be medium frequency alternating current or high frequency alternating current. When the magnitude of the current is different, the strength of the alternating magnetic field and the strength of the eddy current are different. Therefore, by controlling the magnitude of the current, the temperature of the first mold 33 and the second mold 34 at each station can be controlled.

[0098] In the molding apparatus 30 of this application, the first action 37 controls the temperature of the first mold 33 by electromagnetic induction, and the second action 38 controls the temperature of the second mold 34 by electromagnetic induction, so that the molding apparatus 30 can accurately control the temperature of the glass part through the second mold 34 and the first mold 33, the glass part processing and molding steps can be carried out in an orderly and normal manner, and the yield of the generated glass products is high.

[0099] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, the first action member 37 and the second action member 38 are used to generate heat by passing electricity and radiating heat to the first mold 33 and the second mold 34, so as to raise the temperature of the first mold 33 and the second mold 34.

[0100] Specifically, in the above embodiments, the first actuating element 37 can be one or more of the following electrothermal elements: a heating rod, a heating wire, or a heating film. When the first actuating element 37 is energized, it generates heat. When the first actuating element 37 is in direct contact with the first mold 33, it can directly radiate heat to the first mold 33 and control the temperature of the first mold 33, thereby raising the temperature of the first mold 33 and heating the glass piece. When the first actuating element 37 is not in contact with the first mold 33, it can directly radiate heat to the first mold 33 through air or by acting as a heat-conducting structure, and control the temperature of the first mold 33, thereby raising the temperature of the first mold 33 and heating the glass piece.

[0101] The second actuating element 38 can be one or a combination of more than one of the following electrothermal elements: a heating rod, a heating wire, or a heating film. When the second actuating element 38 is energized, it generates heat. When the second actuating element 38 is in direct contact with the second mold 34, it can directly radiate heat to the second mold 34 and control its temperature, thereby raising the temperature of the second mold 34 and heating the glass piece. When the second actuating element 38 is not in contact with the second mold 34, it can directly radiate heat to the second mold 34 through air or a heat-conducting structure, and control its temperature, thereby raising the temperature of the second mold 34 and heating the glass piece. The first actuating element 37 and the second actuating element 38 can be the same or different; for example, the first actuating element 37 can be a heating rod, and the second actuating element 38 can be a heating wire.

[0102] In the molding apparatus 30 of this application, the first working element 37 is energized to generate heat and controls the temperature of the first mold 33 through thermal radiation. The second working element 38 is energized to generate heat and controls the temperature of the second mold 34 through thermal radiation. This enables the molding apparatus 30 to accurately control the temperature of the glass part through the second mold 34 and the first mold 33, allowing the glass part processing and molding steps to proceed in an orderly and normal manner, and resulting in a high yield of the generated glass products.

[0103] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 8In some embodiments, the molding apparatus 30 further includes a loading tray 36, a first transfer assembly 391, and a second transfer assembly 393. The loading tray 36 is spaced apart from the mounting tray 31. The first transfer assembly 391 is disposed on the loading tray 36 and corresponds to the loading station 311. The first transfer assembly 391 is used to acquire the second mold 34 corresponding to the loading station 311, so that the second mold 34 moves relative to the corresponding first mold 33 to open or close the mold. The second transfer assembly 393 is disposed on the loading tray 36 and corresponds to the unloading station 315. The second transfer assembly 393 is used to acquire the second mold 34 corresponding to the unloading station 315, so that the second mold 34 moves relative to the corresponding first mold 33 to open or close the mold.

[0104] Specifically, the first transfer assembly 391 is a structure in the forming device 30 used to acquire the second mold 34 corresponding to the loading station 311. The first transfer assembly 391 is connected to the loading tray 36 and is opposite to the mounting tray 31. The connection between the first transfer assembly 391 and the loading tray 36 can be either detachable or non-detachable. The first transfer assembly 391 corresponds to the loading station 311 to easily and quickly acquire the second mold 34 corresponding to the loading station 311. At this time, when the second mold 34 corresponding to the loading station 311 is moved away from the mounting tray 31 by the first transfer assembly 391, the second mold 34 opens away from the corresponding first mold 33, and the preheated glass part can be placed in the first mold 33; when the second mold 34 corresponding to the loading station 311 is moved closer to the mounting tray 31 by the first transfer assembly 391, the second mold 34 closes closer to the corresponding first mold 33, and the preheated glass part can be accommodated in the first mold 33 and the second mold 34 and heated.

[0105] The second transfer assembly 393 is a structure in the forming apparatus 30 used to acquire the second mold 34 corresponding to the unloading station 315. The second transfer assembly 393 is connected to the loading tray 36 and is opposite to the mounting tray 31. The connection between the second transfer assembly 393 and the loading tray 36 can be detachable or non-detachable. The second transfer assembly 393 corresponds to the unloading station 315 to easily and quickly acquire the second mold 34 corresponding to the unloading station 315. At this time, when the second mold 34 corresponding to the unloading station 315 is moved away from the mounting tray 31 by the second transfer assembly 393, the second mold 34 opens away from the corresponding mold 34, and the formed glass part can be taken out from the second mold 34; when the second mold 34 corresponding to the unloading station 315 is moved closer to the mounting tray 31 by the second transfer assembly 393, the second mold 34 closes closer to the corresponding mold 34, and the closed mold 34 can be combined with the first mold 33 to process the next glass part (refer to the first embodiment).

[0106] Therefore, in the molding apparatus 30 of this application, at the loading station 311, the first transfer component 391 can move the second mold 34 relative to the corresponding first mold 33 to open or close the mold; at the unloading station 315, the second transfer component 393 can move the second mold 34 relative to the corresponding first mold 33 to open or close the mold. At this time, the molding apparatus 30 can carry out the processing steps of the glass parts processed in sequence in an orderly manner without interfering with each other. The molding system 100 realizes the production line and greatly improves the production capacity.

[0107] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 8 In some embodiments, the first transfer assembly 391 includes a first drive member 3911 and a first transfer member 3913. The first drive member 3911 is disposed on the loading tray 36. The first transfer member 3913 is connected to the first drive member 3911. The first drive member 3911 is used to drive the first transfer member 3913 to move closer to or away from the mounting tray 31. The first transfer member 3913 is used to acquire the second mold 34 corresponding to the loading station 311.

[0108] Specifically, the first driving component 3911 is a structure in the first transfer assembly 391 used to drive the first transfer component 3913. The first driving component 3911 can be, but is not limited to, a servo motor, a stepper motor, or a direct drive motor (DD motor). The first driving component 3911 is connected to the loading tray 36, and the connection between the first driving component 3911 and the loading tray 36 can be detachable or non-detachable. The first transfer component 3913 is a structure in the first transfer assembly 391 used to directly acquire the second mold 34. For example, the first transfer component 3913 can be a mechanical gripper. The first transfer component 3913 is connected to the first driving component 3911, and the connection between the first transfer component 3913 and the first driving component 3911 can be detachable or non-detachable.

[0109] When the first driving member 3911 drives the first transfer member 3913 closer to the mounting plate 31, the first transfer member 3913 approaches the second mold 34 corresponding to the loading station 311. At this time, the first transfer member 3913 can acquire the second mold 34 corresponding to the loading station 311, so that the second mold 34 can move relative to the corresponding first mold 33 to open or close the mold. Furthermore, the first driving member 3911 can drive the first transfer member 3913 away from the mounting plate 31.

[0110] In the first embodiment, the second mold 34 corresponding to the loading station 311 is initially supported on the corresponding first mold 33, and the initial position of the first transfer member 3913 is spaced relative to the mounting plate 31. The first driving member 3911 first drives the first transfer member 3913 closer to the mounting plate 31, and the first transfer member 3913 approaches and acquires the second mold 34 corresponding to the loading station 311, so that the second mold 34 can move relative to the corresponding first mold 33 to open the mold, so that the preheated glass part can be placed into the first mold 33 on the loading station 311. Then, the first driving member 3911 drives the first transfer member 3913 away from the mounting plate 31, and the first transfer member 3913 moves the acquired second mold 34 corresponding to the loading station 311 away from the corresponding first mold 33. Next, with the preheated glass part placed into the first mold 33 on the loading station 311, the first drive member 3911 drives the first transfer member 3913 closer to the mounting plate 31. The first transfer member 3913 releases the second mold 34 corresponding to the loading station 311, so that the second mold 34 and the first mold 33 close together. Finally, the first drive member 3911 drives the first transfer member 3913 away from the mounting plate 31, and the first transfer member 3913 resets to begin the next preheated glass part processing. It can be understood that at this time, the first mold 33 and the second mold 34 corresponding to the loading station 311 jointly house and heat the preheated glass part to a second temperature, and after heating, they jointly rotate with the mounting plate 31 to the forming station 313 for subsequent processing and forming.

[0111] In the second embodiment, the second mold 34 corresponding to the loading station 311 is initially acquired by the first transfer component 391, and the initial position of the first transfer component 3913 is spaced relative to the mounting plate 31. The first driving component 3911 first drives the first transfer component 3913 closer to the mounting plate 31. The first transfer component 3913 and the second mold 34 acquired by the first transfer component 3913 (i.e., the second mold 34 corresponding to the loading station 311) approach the first mold 33 on the loading station 311, so that the second mold 34 can move relative to the corresponding first mold 33 to close the mold. At this time, the first mold 33 and the second mold 34 corresponding to the loading station 311 jointly accommodate and heat the preheated glass part to the second temperature. After heating is completed, the first driving component 3911 drives the first transfer component 3913 away from the mounting plate 31, and the first transfer component 3913 and the second mold 34 acquired by the first transfer component 3913 reset to perform the next preheated glass part processing process. It is understandable that at this time, the first mold 33 corresponding to the loading station 311 and the glass part under the second temperature will rotate together with the mounting plate 31 to the forming station 313 for subsequent processing and forming.

[0112] Therefore, in the molding apparatus 30 of this application, at the loading station 311, the first transfer member 3913 can move closer to or further away from the mounting plate 31 under the drive of the first driving member 3911, so that when it is close to the mounting plate 31, it can acquire the second mold 34 corresponding to the loading station 311, thereby causing the second mold 34 to move relative to the corresponding first mold 33 to open or close the mold. At this time, the molding apparatus 30 can carry out the processing steps of the glass parts processed sequentially in an orderly manner without interfering with each other, and the molding system 100 realizes the production line, greatly improving the production capacity.

[0113] The structure of the second transfer assembly 393 is basically the same as that of the first transfer assembly 391, and will not be elaborated here. The difference lies in that the second transfer member 3933 in the second transfer assembly 393 is used to acquire the second mold 34 corresponding to the unloading station 315. When the second transfer assembly 393 performs the acquisition, with the second driving member 3931 driving the second transfer member 3933 closer to the mounting plate 31, the second transfer member 3933 approaches the second mold 34 corresponding to the unloading station 315. At this time, the second transfer member 3933 can acquire the second mold 34 corresponding to the unloading station 315, so that the second mold 34 can move relative to the corresponding first mold 33 to open or close the mold. Furthermore, the second driving member 3931 can drive the second transfer member 3933 away from the mounting plate 31.

[0114] Specifically, in the first embodiment, the second mold 34 corresponding to the unloading station 315 is initially supported on the corresponding second mold 34, and the initial position of the second transfer member 3933 is spaced relative to the mounting plate 31. The second driving member 3931 first drives the second transfer member 3933 to approach the mounting plate 31, and the second transfer member 3933 approaches and acquires the second mold 34 corresponding to the unloading station 315, so that the second mold 34 can move relative to the corresponding first mold 33 to open the mold, so that the formed glass part can be taken out from the first mold 33 on the unloading station 315. Then, the second driving member 3931 drives the second transfer member 3933 away from the mounting plate 31, and the second transfer member 3933 moves the acquired second mold 34 corresponding to the unloading station 315 away from the corresponding second mold 34. Next, after the formed glass part is removed from the first mold 33 at the unloading station 315, the second drive member 3931 drives the second transfer member 3933 to approach the mounting plate 31. The second transfer member 3933 releases the second mold 34 corresponding to the unloading station 315, so that the second mold 34 and the first mold 33 close together. Finally, the second drive member 3931 drives the second transfer member 3933 away from the mounting plate 31, and the second transfer member 3933 resets to begin the next preheated glass part processing. It can be understood that at this time, the second mold 34 and the first mold 33 corresponding to the unloading station 315 are empty of glass parts and rotate together with the mounting plate 31 to the loading station 311 for subsequent processing and forming.

[0115] In the second embodiment, the second mold 34 corresponding to the unloading station 315 is initially acquired by the second transfer component 393. The initial position of the second transfer component 3933 is spaced relative to the mounting plate 31, and the second transfer component 3933 and the second mold 34 corresponding to the unloading station 315 acquired by the second transfer component 3933 generally do not move during the processing. However, the second driving component 3931 has the function of driving the second transfer component 3933 to move closer to or away from the mounting plate 31, and the second transfer component 3933 has the function of taking off the second mold 34 corresponding to the unloading station 315. In other embodiments, the second transfer component 393 may use the above functions to control the opening or closing of the first mold 33 and the second mold 34 corresponding to the unloading station 315.

[0116] Similarly, in the second transfer component 393 of this application, at the unloading station 315, the second transfer member 3933 can move closer to or further away from the mounting plate 31 under the drive of the second drive member 3931, so that when it is close to the mounting plate 31, it can acquire the second mold 34 corresponding to the unloading station 315, thereby causing the second mold 34 to move relative to the corresponding first mold 33 to open or close the mold. At this time, the forming device 30 can carry out the processing steps of the glass parts processed in sequence in an orderly manner without interfering with each other. The forming system 100 realizes the production line, greatly improves the production capacity, and the yield rate of the generated glass products is high. It can also enable the first mold 33 and the second mold 34 at each station to cooperate well with each other, avoiding the glass parts from being unable to carry out the processing and forming steps normally at a certain station, resulting in processing and forming stagnation.

[0117] Please refer to Figure 1 and Figure 2 In some embodiments, the molding apparatus 30 includes a first side 301 and a second side 303, which are adjacent to each other. The preheating device 10 is disposed on the first side 301 of the molding apparatus 30, and the annealing device 50 is disposed on the second side 303 of the molding apparatus 30.

[0118] For details, please refer to Figure 1 and Figure 2 Taking the overall shape of the molding device 30 as rectangular as an example, the molding device 30 includes a first side 301, a second side 303, a third side 305, and a fourth side 307 connected end to end. The first side 301 is the side of the molding device 30 opposite to the preheating device 10, and the second side 303 is the side of the molding device 30 opposite to the annealing device 50. It can be understood that the second side 303 is adjacent to the first side 301, not opposite to it. With the molding device 30, preheating device 10, and annealing device 50 arranged in the above orientation, the overall shape of the molding system 100 is "L-shaped," as shown below. Figure 1 and Figure 2 As shown, compared to the molding system 100 arranged in only one direction, the "L-shaped" molding system 100 of this application is arranged in two directions, with a smaller footprint in both directions, making it easier to lay out the molding system 100 on a site.

[0119] Please refer to Figure 1 and Figure 3 In some embodiments, the forming system 100 further includes a first transfer mechanism 70 and a second transfer mechanism 80. The first transfer mechanism 70 is used to remove the preheated glass part from the preheating device 10 and transfer it to the first mold 33 on the loading station 311. The second transfer mechanism 80 is used to remove the formed glass part from the first mold 33 on the unloading station 315 and transfer the formed glass part to the annealing device 50.

[0120] Specifically, the first transfer mechanism 70 is used to remove the preheated glass piece from the preheating device 10 and transfer it to the first mold 33 on the loading station 311. The first transfer mechanism 70 can be, but is not limited to, a robotic arm, a transfer robot, or other structure capable of transferring the glass piece. The first transfer mechanism 70 has good high-temperature resistance to prevent the preheated glass piece from burning it. The second transfer mechanism 80 is used to remove the formed glass piece from the first mold 33 on the unloading station 315 and transfer it to the annealing device 50. The second transfer mechanism 80 can be, but is not limited to, a robotic arm, a transfer robot, or other structure capable of transferring the glass piece. The second transfer mechanism 80 has good high-temperature resistance to prevent the formed glass piece from burning it.

[0121] In some embodiments, the first transfer mechanism 70 and the second transfer mechanism 80 can be the same transfer mechanism. In this case, the process of removing the preheated glass part from the preheating device 10 and transferring it to the first mold 33 on the loading station 311 is alternated with the process of removing the formed glass part from the first mold 33 on the unloading station 315 and transferring it to the annealing device 50. In other embodiments, the first transfer mechanism 70 and the second transfer mechanism 80 can be different transfer mechanisms. In this case, the first transfer mechanism 70 and the second transfer mechanism 80 can be the same type of transfer mechanism or different types of transfer mechanisms. The two transfer processes can be performed simultaneously, which can greatly improve the transfer efficiency and thus improve the processing and forming efficiency of the forming system 100.

[0122] Therefore, the forming system 100 of this application takes the preheated glass part out of the preheating device 10 and transfers it to the first mold 33 on the loading station 311 through the first transfer mechanism 70, and takes the formed glass part out of the first mold 33 on the unloading station 315 and transfers it to the annealing device 50 through the second transfer mechanism 80. The glass part processing and forming steps can be carried out in an orderly and normal manner, and the yield and efficiency of the generated glass products are both high.

[0123] Please refer to Figure 1 and Figure 3In some embodiments, the first transfer mechanism 70 includes a suction member 71 and a two-axis rotating arm 73 or a three-axis rotating arm 73 connected to the suction member 71. The suction member 71 is used to suction and release the glass piece. The two-axis rotating arm 73 is used to rotate about the yaw axis and the pitch axis to align the suction member 71 with the preheated glass piece to be removed from the preheating device 10 or with the first mold 33 on the loading station 311. The three-axis rotating arm 73 is used to rotate about the yaw axis, the pitch axis, and the roll axis to align the suction member 71 with the preheated glass piece to be removed from the preheating device 10 or with the first mold 33 on the loading station 311.

[0124] Specifically, the suction member 71 is a structure used to suction and release glass components using negative pressure. At least a portion of the suction member 71 is in contact with the glass component, forming a sealed air cavity. The suction member 71 creates a negative pressure environment in the air cavity by drawing air from it. Therefore, the glass component is adsorbed by the suction member 71 under the influence of external atmospheric pressure. When the negative pressure environment in the air cavity is broken, the negative pressure environment disappears, and the glass component is released by the suction member 71. Movement of the suction member 71 can cause the glass component adsorbed on it to move.

[0125] The two-axis rotating arm 73 is a structure capable of rotating about the yaw and pitch axes to drive the suction member 71 connected to it. The two-axis rotating arm 73 is connected to the suction member 71 at its free end or near the free end. The connection between the two-axis rotating arm 73 and the suction member 71 can be detachable or non-detachable. In some embodiments of this application, the two-axis rotating arm 73 can rotate about the yaw and pitch axes to align the suction member 71 with the preheated glass piece to be removed in the preheating device 10 or with the first mold 33 on the loading station 311. The two-axis rotating arm 73 provides two rotational degrees of freedom for the suction member 71.

[0126] At this time, when the first transfer mechanism 70 is performing the transfer, the two-axis rotating arm 73 can first adjust the rotation of two degrees of freedom to align the suction member 71 with the preheated glass piece to be removed in the preheating device 10; then, the suction member 71 can use negative pressure to suction the preheated glass piece; then, the two-axis rotating arm 73 can again adjust the rotation of two degrees of freedom to align the suction member 71 with the first mold 33 on the loading station 311; finally, the suction member 71 can break the negative pressure environment to release the preheated glass piece, so that it can be accurately placed into the first mold 33 on the loading station 311.

[0127] The three-axis rotary arm 73 is a structure capable of rotating about the yaw axis, pitch axis, and roll axis to drive the suction member 71 connected to it. The three-axis rotary arm 73 is connected to the suction member 71 at or near its free end. The connection between the three-axis rotary arm 73 and the suction member 71 can be detachable or non-detachable. In some embodiments of this application, the three-axis rotary arm 73 can rotate about the yaw axis, pitch axis, and roll axis to align the suction member 71 with the preheated glass piece to be removed in the preheating device 10 or with the first mold 33 on the loading station 311. The three-axis rotary arm 73 provides three rotational degrees of freedom for the suction member 71.

[0128] At this time, when the first transfer mechanism 70 is performing the transfer, the three-axis rotating arm 73 can first adjust the rotation of the three rotational degrees of freedom to align the suction member 71 with the preheated glass piece to be removed in the preheating device 10; then, the suction member 71 can use negative pressure to suction the preheated glass piece; then, the three-axis rotating arm 73 can again adjust the rotation of the three rotational degrees of freedom to align the suction member 71 with the first mold 33 on the loading station 311; finally, the suction member 71 can break the negative pressure environment to release the preheated glass piece, so that it can be accurately placed into the first mold 33 on the loading station 311.

[0129] Therefore, in the first transfer mechanism 70 of this application, the two-axis rotating arm 73 or the three-axis rotating arm 73 is connected to the suction member 71 and provides the suction member 71 with two or three degrees of rotational freedom. This allows the suction member 71 to be more accurately aligned with the preheated glass piece to be removed from the preheating device 10, so as to achieve the suction of the preheated glass piece without causing it to fall. At this time, the glass processing and forming steps can be carried out in an orderly and normal manner, and the yield of the generated glass products is high. It also allows the suction member 71 to be more accurately aligned with the first mold 33 on the loading station 311, so as to avoid the preheated glass piece being unable to be loaded into the first mold 33, resulting in the processing and forming stopping.

[0130] The structure of the second transfer mechanism 80 is basically the same as that of the first transfer mechanism 70, and will not be elaborated here. The difference between the two is that the two-axis rotating arm 73 or the three-axis rotating arm 73 in the second transfer mechanism 80 drives the suction member 71 to align with the glass part in the first mold 33 on the unloading station 315 or with the second carrier 51 in the annealing device 50. When the second transfer mechanism 80 performs the transfer, its two-axis rotating arms 73 can first be adjusted by two rotational degrees of freedom to align the suction component 71 of the second transfer mechanism 80 with the glass component in the first mold 33 on the unloading station 315. Then, the suction component 71 of the second transfer mechanism 80 can use negative pressure to suction the glass component in the first mold 33 on the unloading station 315. Next, the two-axis rotating arms 73 of the second transfer mechanism 80 can again be adjusted by two rotational degrees of freedom to align the suction component 71 with the second carrier 51 in the annealing device 50. Finally, the suction component 71 can break the negative pressure environment to release the adsorbed glass component, allowing it to be accurately placed on the second carrier 51. Similarly, if the second transfer mechanism 80 has a three-axis rotating arm 73, it can rotate with three degrees of freedom. The specific transfer process can be performed accordingly and will not be detailed here.

[0131] Similarly, in the second transfer mechanism 80 of this application, a two-axis rotating arm 73 or a three-axis rotating arm 73 is connected to the suction member 71, providing the suction member 71 with two or three degrees of rotational freedom. This allows the suction member 71 to be more precisely aligned with the glass part in the first mold 33 on the unloading station 315, ensuring that the glass part is picked up from the first mold 33 on the unloading station 315 without falling off. In this case, the glass part processing steps can proceed in an orderly and normal manner, resulting in a high yield rate of the generated glass products. Furthermore, it allows the suction member 71 to be more precisely aligned with the second carrier 51 in the annealing device 50, preventing the glass part from failing to be loaded onto the second carrier 51 and causing processing to stall. In addition, the second transfer mechanism 80 and the first transfer mechanism 70 can also be other mobile mechanisms with transfer functions.

[0132] Please refer to Figure 1 and Figure 3 In some embodiments, at least one of the first transfer mechanism 70 and the second transfer mechanism 80 further includes a heating unit disposed on at least one of the rotating arm 73 and the suction member 71. The heating unit is used to heat the suction member 71 before the suction member 71 picks up the glass piece, so that the temperature of the suction member 71 is close to the temperature of the glass piece.

[0133] Specifically, the heating unit (not shown) is a structure used to heat the suction member 71 so that the suction member 71 transfers heat to the glass piece adsorbed by the suction member 71. In some embodiments, the heating unit is disposed on the rotating arm 73, in which case the electrical connection path of the heating unit is shorter. In other embodiments, the heating unit is disposed on the suction member 71, in which case the temperature of the heating unit can be transferred to the suction member 71 more quickly. In still other embodiments, the heating unit is disposed on both the rotating arm 73 and the suction member 71, in which case the heating unit covers a larger area, generates more heat, and can more thoroughly heat the suction member 71.

[0134] During the process of the suction unit 71 removing the preheated glass part from the preheating device 10 and transferring it to the first mold 33 on the loading station 311, or during the process of the suction unit 71 removing the formed glass part from the first mold 33 on the unloading station 315 and transferring it to the annealing device 50, if the temperature difference between the suction unit 71 and the glass part is too large, the glass part will exchange heat with the suction unit 71 and its temperature will drop. To prevent the glass part from breaking due to a sudden drop in temperature, the heating unit starts heating before the suction unit 71 picks up the glass part. At this time, the suction unit 71 contacts the glass part when its temperature is close to that of the glass part, and the glass part will not break due to cold. Therefore, at least one of the first transfer mechanism 70 and the second transfer mechanism 80 of this application heats the suction unit 71 through the heating unit, which prevents the glass part from breaking due to cold during the transfer process. At this time, the glass part processing and forming steps can be carried out in an orderly and normal manner, and the yield of the generated glass products is high.

[0135] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 In some embodiments, the preheating device 10 includes a first carrier 11, which is made of a different material than the second mold 34. The first carrier 11 is used to load the initial glass piece and can move towards the forming device 30. The preheating device 10 includes at least one preheating zone 101, in which a heating element 12 is disposed to heat the preheating zone 101. When there are multiple preheating zones 101, the multiple preheating zones 101 are sequentially connected in the direction from the preheating device 10 to the forming device 30. The heating elements 12 in different preheating zones 101 can be independently controlled so that the temperature of the initial glass piece on the first carrier 11 gradually increases in the direction from the preheating device 10 to the forming device 30.

[0136] Specifically, the first carrier 11 is the structure in the preheating device 10 used to load the initial glass piece. The material of the first carrier 11 is different from that of at least one of the second mold 34 and the first mold 33. Generally, the first carrier 11 has at least one advantage over at least one of the second mold 34 and the first mold 33: lower cost, easier maintenance, and longer service life. The process of loading the initial glass piece into the first carrier 11 can be performed by a worker or by a third transfer mechanism (not shown), and this application does not limit this. When the initial glass piece is loaded into the first carrier 11, the first carrier 11 moves the initial glass piece toward the forming device 30.

[0137] The preheating zone 101 is the area in the preheating device 10 used to heat the initial glass piece. The heating element 12 is a structure disposed in the preheating zone 101 for heating the preheating zone 101. The heating element 12 may be, but is not limited to, at least one of a heating tube, a resistance heating wire, a silicon carbide rod, an infrared heater, or a quartz heater. The heating element 12 heats the preheating zone 101 so that the glass piece moving towards the forming device 30 within the preheating zone 101 is heated.

[0138] The number of preheating zones 101 can be one, in which case the structure of the preheating device 10 is relatively simple. The number of preheating zones 101 can be multiple, in which case the preheating device 10 can heat the glass piece more precisely. In the direction from the preheating device 10 to the forming device 30, i.e., the direction of movement of the glass piece, multiple preheating zones 101 are connected sequentially, and adjacent preheating zones 101 are interconnected. Each preheating zone 101 is equipped with a heating element 12, and the heating element 12 in each preheating zone 101 is independently controlled, thus the temperature in the preheating zone 101 is independently controlled. As the initial glass piece located on the first carrier 11 moves towards the forming device 30, the initial glass piece follows the first carrier 11, sequentially passing through each preheating zone 101.

[0139] In some embodiments, the initial temperature of the glass component increases linearly with motion, resulting in a relatively gradual temperature rise and uniform preheating with low internal stress. In other embodiments, the initial temperature of the glass component increases gradient with motion, making temperature control in each preheating zone 101 easier. In still other embodiments, the initial temperature of the glass component increases both linearly and gradient with motion; for example, the initial temperature increases rapidly with a gradient in the early stages of heating, and then increases steadily linearly as it approaches the first temperature to ensure that the first temperature is reached. This allows for more flexible preheating of the initial glass component.

[0140] Therefore, the preheating device 10 controls the temperature of the preheating zone 101 through the heating element 12, thereby controlling the initial preheating process of the glass piece. When there are multiple preheating zones 101, the preheating device 10 can gradually increase the temperature of the initial glass piece in the direction from the preheating device 10 to the forming device 30 by independently controlling the heating element 12 in different preheating zones 101. The initial preheating process of the glass piece can achieve accurate temperature control, and the temperature of the preheated glass piece can better meet the needs of the subsequent processing and forming steps. Therefore, the processing and forming steps of the glass piece can proceed in an orderly and normal manner, and the yield of the generated glass products is high.

[0141] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 9 In some embodiments, the preheating device 10 includes a first conveying assembly 13, a first return assembly 15, a first transfer assembly 17, and a second transfer assembly 19. The first conveying assembly 13 includes a first loading end 131 and a first unloading end 133, which are opposite to each other in the direction from the preheating device 10 to the forming device 30, with the first unloading end 133 being closer to the forming device 30 than the first loading end 131. The first conveying assembly 13 carries a first carrier 11 and transfers the first carrier 11, loaded with an initial glass piece, towards the first unloading end 133. The first return assembly 15 includes a first loading end 151 and a first unloading end 153, which are opposite to each other in the direction from the preheating device 10 to the forming device 30, with the first loading end 151 being closer to the forming device 30 than the first unloading end 153. The first return assembly 15 carries the first carrier 11 and transfers the first carrier 11 after unloading the preheated glass component to the first download end 153. The first transfer assembly 17 is disposed near the first loading end 131 and the first download end 153 and is used to transfer the first carrier 11 on the first download end 153 to the first loading end 131. The second transfer assembly 19 is disposed near the first unloading end 133 and the first loading end 151 and is used to transfer the first carrier 11 on the first unloading end 133 to the first loading end 151.

[0142] Specifically, the first conveying assembly 13 is a structure used to carry the first carrier 11 and convey the first carrier 11, which is loaded with the initial glass piece, to the forming device 30. The first loading end 131 is the end of the first conveying assembly 13 used to load the initial glass piece onto the first carrier 11, and the first unloading end 133 is the end of the first conveying assembly 13 used to transfer the preheated glass piece to the forming device 30 by the first transfer mechanism 70. It can be understood that in the direction from the preheating device 10 to the forming device 30, that is, in the direction of movement of the first carrier 11 loaded with the initial glass piece, the first loading end 131 and the first unloading end 133 are opposite each other, and the first unloading end 133 is closer to the forming device 30 than the first loading end 131.

[0143] The first return assembly 15 is a structure used to carry the first carrier 11 and convey the first carrier 11, after unloading and preheating the glass piece, to the first download end 153. The first loading end 151 is one end of the first return assembly 15 used to receive the first carrier 11, after unloading and preheating the glass piece, and the first download end 153 is one end of the first return assembly 15 used to transfer the first carrier 11, after unloading and preheating the glass piece, to the first feeding end 131 of the first conveying assembly 13. It can be understood that in the direction from the forming device 30 to the preheating device 10, that is, in the opposite direction to the movement direction of the first carrier 11 loaded with the initial glass piece, the first loading end 151 and the first download end 153 are opposite each other, and the first loading end 151 is closer to the forming device 30 than the first download end 153.

[0144] The first transfer assembly 17 is used to transfer the first carrier 11 on the first download end 153 to the first loading end 131. The transferred first carrier 11 is the carrier 11 that has already unloaded the preheated glass component. The transferred first carrier 11 can carry the initial glass component on the first loading end 131, thus enabling the first carrier 11 to be reused. The first transfer assembly 17 is positioned close to both the first loading end 131 and the first download end 153, so that the first transfer assembly 17 can easily and quickly transfer the first carrier 11 from the first download end 153 to the first loading end 131.

[0145] The second transfer assembly 19 is used to transfer the first carrier 11 on the first unloading end 133 to the first loading end 151. At this time, the first carrier 11 being transferred is the first carrier 11 unloaded from the preheated glass component. The transferred first carrier 11 can be conveyed to the first unloading end 153 by the first return assembly 15 to realize the recycling of the first carrier 11. The second transfer assembly 19 is positioned close to both the first unloading end 133 and the first loading end 151 so that the second transfer assembly 19 can easily and quickly transfer the first carrier 11 on the first unloading end 133 to the first loading end 151.

[0146] Therefore, in the molding apparatus 30 of this application, the preheating device 10 realizes the cyclic use of the first carrier 11 through the first conveying component 13, the first return component 15, the first transfer component 17, and the second transfer component 19. The first carrier 11 carries the initial glass piece at the first loading end 131. The first conveying component 13 conveys the first carrier 11 carrying the initial glass piece to the first unloading end 133. The second transfer component 19 transfers the first carrier 11 carrying the unloaded preheated glass piece from the first unloading end 133 to the first loading end 151. The transferred first carrier 11 can be conveyed to the first unloading end 153 by the first return component 15. The first transfer component 17 transfers the first carrier 11 from the first unloading end 153 to the first loading end 131. The transferred first carrier 11 can carry the initial glass piece at the first loading end 131, thereby realizing the cyclic use of the first carrier 11. At this time, the preheating device 10 has a high working efficiency and requires a small number of first carriers 11. The preheating process can be carried out efficiently and orderly so that the glass processing and forming steps can be carried out in an orderly and normal manner, resulting in a high yield of the generated glass products.

[0147] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 In some embodiments, the annealing apparatus 50 includes a second carrier 51, which is made of a different material than the second mold 34. The second carrier 51 is used to load the formed glass piece and can move away from the forming apparatus 30. The annealing apparatus 50 includes at least one annealing region 501, and a heat-insulating member 52 is provided in the annealing region 501 to keep the annealing region 501 warm. When there are multiple annealing regions 501, the multiple annealing regions 501 are connected sequentially in the direction from the forming apparatus 30 to the annealing apparatus 50. The heat-insulating members 52 in different annealing regions 501 can be controlled independently so that the temperature of the formed glass piece on the second carrier 51 gradually decreases in the direction from the forming apparatus 30 to the annealing apparatus 50.

[0148] Specifically, the second carrier 51 is a structure in the annealing apparatus 50 used to load the formed glass piece. The material of the second carrier 51 is different from that of at least one of the second mold 34 and the first mold 33. Generally, the second carrier 51 has at least one advantage over at least one of the second mold 34 and the first mold 33: lower cost, easier maintenance, and longer service life. The process of removing the annealed glass piece from the second carrier 51 can be performed by a worker or by a fourth transfer mechanism (not shown), and this application does not limit this. When the formed glass piece is loaded in the second carrier 51, the second carrier 51 moves the formed glass piece away from the forming apparatus 30.

[0149] Annealing zone 501 is the area in annealing apparatus 50 used to cool the formed glass part. A heat-insulating element 52 is disposed in annealing zone 501 to keep the annealing zone 501 warm, so that the temperature of the formed glass part decreases slowly. The heat-insulating element 52 may be, but is not limited to, at least one of a heating tube, resistance furnace wire, silicon carbide rod, infrared heater, or quartz heater. The heat-insulating element 52 heats annealing zone 501 so that the temperature of the glass part moving towards the forming apparatus 30 within annealing zone 501 can decrease slowly.

[0150] The number of annealing zones 501 can be one, in which case the structure of the annealing device 50 is relatively simple. The number of annealing zones 501 can be multiple, in which case the annealing device 50 can achieve more precise cooling of the glass component. In the direction from the forming device 30 to the annealing device 50, i.e., the direction of movement of the glass component, multiple annealing zones 501 are sequentially connected, and adjacent annealing zones 501 are interconnected. Each annealing zone 501 is equipped with a heat-insulating element 52, and the heat-insulating element 52 in each annealing zone 501 is independently controlled, thus the temperature in each annealing zone 501 is independently controlled. As the formed glass component on the second carrier 51 moves towards the forming device 30, the formed glass component sequentially passes through each annealing zone 501.

[0151] In some embodiments, the temperature of the formed glass part decreases linearly with movement, resulting in a relatively gradual temperature drop and uniform annealing with low internal stress. In other embodiments, the temperature of the formed glass part decreases gradually with movement, making temperature control in each annealing zone 501 easier. In still other embodiments, the temperature of the formed glass part decreases both linearly and gradually with movement. For example, it decreases slowly and linearly in the early stages of cooling to prevent the glass part from cracking due to cold, and then gradually increases to rapidly cool it as it approaches room temperature. This allows for greater flexibility in the annealing process of the formed glass part.

[0152] Therefore, the annealing device 50 controls the temperature of the annealing zone 501 through the heat preservation element 52, thereby controlling the annealing process of the formed glass part. When there are multiple annealing zones 501, the annealing device 50 can gradually reduce the temperature of the formed glass part in the direction from the forming device 30 to the annealing device 50 by independently controlling the heat preservation element 52 in different annealing zones 501. The annealing process of the formed glass part can achieve accurate temperature control, and the annealed glass part will not break and has good performance. Therefore, the glass part processing and forming steps can be carried out in an orderly and normal manner, and the yield of the generated glass products is high.

[0153] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 10 In some embodiments, the annealing apparatus 50 includes a second conveying assembly 53, a second return assembly 55, a third transfer assembly 57, and a fourth transfer assembly 59. The second conveying assembly 53 includes a second loading end 531 and a second unloading end 533, which are opposite to each other in the direction from the annealing apparatus 50 to the forming apparatus 30, with the second loading end 531 being closer to the forming apparatus 30 than the second unloading end 533. The second conveying assembly 53 carries the second carrier 51 and transfers the second carrier 51, loaded with the formed glass piece, towards the second unloading end 533. The second return assembly 55 includes a second loading end 551 and a second unloading end 553, which are opposite to each other in the direction from the annealing apparatus 50 to the forming apparatus 30, with the second unloading end 553 being closer to the forming apparatus 30 than the second loading end 551. The second return assembly 55 carries the second carrier 51 and transfers the second carrier 51, after unloading the glass product, towards the second download end 553. The third transfer assembly 57 is located near the second loading end 531 and the second download end 553 and is used to transfer the second carrier 51 from the second download end 553 to the second loading end 531. The fourth transfer assembly 59 is located near the second unloading end 533 and the second loading end 551 and is used to transfer the second carrier 51 from the second unloading end 533 to the second loading end 551.

[0154] Specifically, the second conveying assembly 53 is a structure used to carry the second carrier 51 and convey the second carrier 51, which is loaded with the formed glass part, to the second unloading end 533. The second loading end 531 is the end of the second conveying assembly 53 used to load the formed glass part onto the second carrier 51, and the second unloading end 533 is the end of the second conveying assembly 53 used to remove the annealed glass product. It can be understood that in the direction from the forming device 30 to the annealing device 50, that is, in the direction of movement of the second carrier 51 loaded with the formed glass part, the second loading end 531 and the second unloading end 533 are opposite each other, and the second loading end 531 is closer to the forming device 30 than the second unloading end 533.

[0155] The second return assembly 55 is a structure used to carry the second carrier 51 and transport the unloaded glass product from the second carrier 51 to the second download end 553. The second loading end 551 is one end of the second return assembly 55 used to receive the unloaded glass product from the second carrier 51, and the second download end 553 is one end of the second return assembly 55 used to transfer the unloaded glass product from the second carrier 51 to the second loading end 531 of the second conveying assembly 53. It can be understood that in the direction from the forming device 30 to the annealing device 50, that is, in the direction of movement of the second carrier 51 loaded with the formed glass part, the second loading end 551 and the second download end 553 are opposite each other, and the second download end 553 is closer to the forming device 30 than the second loading end 551.

[0156] The third transfer assembly 57 is used to transfer the second carrier 51 from the second loading end 553 to the second loading end 531. The transferred second carrier 51 is the same carrier 51 used for unloading glass products. The transferred second carrier 51 can also carry the formed glass parts at the second loading end 531, thus enabling the second carrier 51 to be reused. The third transfer assembly 57 is positioned close to both the second loading end 531 and the second loading end 553, allowing it to easily and quickly transfer the second carrier 51 from the second loading end 553 to the second loading end 531.

[0157] The fourth transfer assembly 59 is used to transfer the second carrier 51 on the second unloading end 533 to the second loading end 551. The transferred second carrier 51 is the carrier 51 used for unloading glass products. The transferred second carrier 51 can be conveyed to the second unloading end 553 by the second return assembly 55, thus enabling the recycling of the second carrier 51. The fourth transfer assembly 59 is positioned close to both the second unloading end 533 and the second loading end 551, allowing it to easily and quickly transfer the second carrier 51 from the second unloading end 533 to the second loading end 551.

[0158] Therefore, in the molding apparatus 30 of this application, the annealing apparatus 50 realizes the cyclic use of the second carrier 51 through the second conveying assembly 53, the second return assembly 55, the third transfer assembly 57 and the fourth transfer assembly 59. The second carrier 51 carries the molded glass part at the second loading end 531. The second conveying assembly 53 conveys the second carrier 51 carrying the molded glass part to the second unloading end 533. The fourth transfer assembly 59 transfers the second carrier 51 unloading the glass product on the second unloading end 533 to the second loading end 551. The transferred second carrier 51 can be conveyed to the second unloading end 553 by the second return assembly 55. The third transfer assembly 57 transfers the second carrier 51 on the second unloading end 553 to the second loading end 531. The transferred second carrier 51 can carry the molded glass part at the second loading end 531, thereby realizing the cyclic use of the second carrier 51. At this time, the annealing device 50 has a high working efficiency and requires fewer second carriers 51. The annealing process can be carried out efficiently and orderly, so that the glass processing and forming steps can be carried out in an orderly and normal manner, and the yield of the generated glass products is high.

[0159] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the molding apparatus 30 further includes a protective component 90 for supplying inert gas to the first mold 33 and the second mold 34.

[0160] Specifically, since the first mold 33 and / or the second mold 34 are graphite molds, metal molds, or ceramic molds, the molding apparatus 30 typically needs to protect these molds to prevent oxidation, which could lead to reduced mold life, affected product quality, or product contamination. The protective component 90 is used to protect the first mold 33 and the second mold 34. The protective component 90 can supply inert gas to the first mold 33 and the second mold 34. The inert gas can be, but is not limited to, at least one of nitrogen, argon, or helium. Therefore, the molding apparatus 30 of this application supplies inert gas to the first mold 33 and the second mold 34 through the protective component 90 to prevent oxidation of the first mold 33 and the second mold 34, thereby avoiding problems such as reduced mold life, affected product quality, or product contamination. In this case, the first mold 33 and the second mold 34 have a longer service life, lower production costs, and a higher yield rate for the produced glass products.

[0161] It is understood that since graphite molds, metal molds or ceramic molds are used more often in the molding device 30 in the molding system 100 of this application, only the protective component 90 needs to be set in the molding device 30 and inert gas needs to be used, while the preheating device 10 and the annealing device 50 do not need to use inert gas. Therefore, the amount of inert gas used in the molding system 100 during the production of glass products is small, and the production cost of glass products is low.

[0162] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0163] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
