Description

Technical Field

[0001] The invention relates to the technical field of glass hot bending and forming, in particular to a hot bending machine for processing and forming a 3D vehicle-mounted display curved glass cover plate. Background Art

[0002] As the trends of electric, intelligent, and internet-based vehicles are increasingly penetrating the automotive market, the demand for automotive 3D cover glass is growing rapidly. In the processing of curved cover glass, 2D glass is generally hot-bent to form a 3D curved glass product.

[0003] The existing Chinese patent application with publication number CN116040925A discloses a precision hot bending machine for continuous hot bending of curved glass cover plates. The conveyor belt is driven by a first servo motor installed on the side of the bracket. The first robot arm is used to place the lower mold on the conveyor belt and place the glass cover plate raw material on the corresponding lower mold. The PLC controller controls the piston rod of the cylinder to extend so that the baffle is used to block the transmission of the lower mold; the PLC controller controls the hydraulic cylinder on the top of the hot bending box to control the upper mold to descend; the CDD industrial camera is used to detect the position of the lower mold, the loading of the glass cover plate raw material of the present invention and the unloading work efficiency after hot bending forming; through the setting of the CDD industrial camera, the position of the lower mold can be accurately located, thereby driving the upper mold to move to just above the lower mold, which is conducive to the next step of realizing accurate mold closing of the upper mold and the lower mold; the preset holding time ensures the holding time of the upper mold on the lower mold, which is conducive to ensuring the quality of hot bending forming of the glass cover plate raw material.

[0004] However, the hot bending machine has the following defects when used:

[0005] 1. When the existing heat bending machine is actually used, it is necessary to first put the straight glass cover into the corresponding graphite mold, and then put the graphite mold into the heat bending equipment for heating and pressing. After the pressing is completed, the pressed 3D curved glass product can be taken out. In this process, a single heat bending machine can only press the straight glass cover in a single mold, and it is necessary to wait during the pressing process. The overall heat bending efficiency is not high, and it is difficult to achieve more efficient long-term cycle processing, which in turn affects the entire processing production line;

[0006] 2. Existing hot bending machines often have large and small edges and warped edges during actual use. This is because the hot bending process parameters of the hot bending machine are set unreasonably, which is mainly manifested in uneven temperature and insufficient preheating. Once the temperature is not uniform, the thickness of the glass will be different, and the radius of curvature will also be affected, which will lead to a decrease in the final yield of the glass cover, which not only affects the production and processing costs of the entire manufacturer, but also affects the overall production and processing progress, which is not conducive to long-term stable operation.

[0041] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0042] 1. In the hot bending machine for processing and forming the curved glass cover plate of the 3D vehicle display, the upper mold assembly will rotate to the top of the next adjacent lower mold assembly each time the first driving assembly is started and closed, and the previous lower mold assembly that originally cooperated with the upper mold assembly for hot bending is in a "neutral" state after completing the hot bending work. At this time, the hot bent part can be reserved for cooling and cooled, and the cooled hot bent part can be taken and the new cover plate to be processed can be placed, realizing a processing logic. After the next group of lower mold assemblies complete the hot pressing, the upper mold assembly will return to the original station, realizing a processing logic again. In this reciprocating cycle, the cover plate on the equipment platform can be cyclically processed-cooled-taken-placed, making the processing logic of the entire processing equipment stronger, more conducive to long-term cyclic processing, and with a more professional processing level;

[0043] 2. In the hot bending machine for processing and forming the 3D vehicle-mounted display curved glass cover plate, when the upper mold body and the lower mold body correspond to each other up and down, the first magnet provided will drive the spring to stretch under the magnetic effect of the second magnet and the first magnet will be stuck in the second groove, so that after the upper mold body and the lower mold body are attached to each other, the two will have a better attachment effect and will not be laterally offset, which is more conducive to the hot bending of the cover plate and improves the quality of the final product;

[0044] 3. In the hot bending machine for processing and forming the curved glass cover plate of the 3D vehicle display, when the second motor is started by the external controller, the second motor can drive the first rotating rod connected thereto to rotate, thereby causing the first gear on the first rotating rod to rotate. Since the first gear is meshed with the second gear, when the second gear rotates, the remaining first gears will also rotate, thereby causing the plurality of second rotating rods to drive the threaded rods to rotate synchronously, so that the plurality of threaded blocks can drive the plurality of upper mold assemblies to rise or fall synchronously. On the one hand, only one second motor can be used to realize the common lifting of the plurality of upper mold assemblies, which is conducive to saving power resources, and the overall control is more uniform, which is convenient for management and control and subsequent adjustment. On the other hand, through the meshing between the first gear and the second gear, the threaded connection between the threaded rod and the threaded block not only makes the lifting distance of the entire upper mold assembly more accurate, but also has a self-locking structure after the upper mold assembly is stopped, so that the overall use is more stable, which is more conducive to subsequent hot bending processing and improves the processing effect.

[0045] 4. In the hot bending machine for processing and forming the 3D vehicle-mounted display curved glass cover plate, the air heating tube is arranged to heat the inside of the arc box. At the same time, under the action of the first connecting hose and the second connecting hose, the inside of the first arc cavity and the second arc cavity both have a certain amount of heat, so that the temperature of the cover plate is always guaranteed when the upper mold body and the lower mold body are connected to each other, which is convenient for better hot bending. At the same time, when the second rotating rod rotates, the meshing of the third gear and the fourth gear will cause the second rotating shaft to rotate synchronously, and then the fan blades will rotate. The rotation of the fan blades can stir the internal air of the arc box, so that the temperature inside the first arc cavity and the second arc cavity is more uniform, which is more conducive to the insulation of the cover plate. The power source of the second rotating shaft is provided by the second motor on the second rotating rod. Therefore, there is no need to add an additional power structure, which further saves power resources and responds to the energy-saving and environmental protection concept.

[0073] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0074] See also Figure 1-Figure 17 , a hot bending machine for processing and forming a curved glass cover plate for a 3D vehicle display, comprising an equipment platform 1, and a plurality of legs are arranged at the bottom of the equipment platform 1, the cross section of the equipment platform 1 is a perfect circular structure, and the above-mentioned hot bending machine for processing and forming a curved glass cover plate for a 3D vehicle display further comprises a lower mold assembly 2, a first rotating shaft 4, an upper mold assembly 3, a first driving assembly 5 and a second driving assembly 6; wherein,

[0075] There are several lower mold assemblies 2, and several lower mold assemblies 2 are arranged at equal intervals on the top of the equipment platform 1 along the circumferential direction of the equipment platform 1. The first rotating shaft 4 is vertically arranged at the center of the top of the equipment platform 1, and the first rotating shaft 4 is rotatably connected to the equipment platform 1. There are several upper mold assemblies 3, and several upper mold assemblies 3 are arranged at equal intervals on the outside of the first rotating shaft 4 along the circumferential direction of the equipment platform 1, and the number of upper mold assemblies 3 is half the number of lower mold assemblies 2. The first driving assembly 5 is arranged on the top of the equipment platform 1, and the first driving assembly 5 is used to drive the first rotating shaft 4 and several upper mold assemblies 3 to rotate with the central axis of the first rotating shaft 4 as the rotation axis. The single rotation degree of the first rotating shaft 4 and several upper mold assemblies 3 is x degrees, and x=36 / the total number of lower mold assemblies 2. The second driving assembly 6 is arranged on the first rotating shaft 4, and the second driving assembly 6 is used to drive the upper mold assembly 3 to rise or fall.

[0076] In this embodiment, the number of upper mold assemblies 3 is three, and the number of lower mold assemblies 2 is six. Specifically, in summary, when in use, according to Figure 1-Figure 3 It can be seen that, since the three upper mold assemblies 3 correspond to only three of the lower mold assemblies 2 one by one, when the 3D vehicle display curved glass cover is bent each time, only three of the cover plates will be bent by the upper mold assembly 3, which makes:

[0077] When the first drive component 5 is started and closed each time, the upper mold component 3 will rotate to the top of the next adjacent lower mold component 2, and the previous lower mold component 2 that was originally matched with the upper mold component 3 for hot bending is in an "neutral" state after completing the hot bending work. At this time, it is possible to reserve cooling time for the hot-bent part and cool it, and to take the cooled hot-bent part and place the new cover plate to be processed, thereby realizing a processing logic. After the next group of lower mold components 2 completes the hot pressing, the upper mold component 3 will return to the original workstation and realize a processing logic again. In this reciprocating cycle, the cover plate on the equipment platform 1 can be cyclically processed-cooled-taken-placed, so that the processing logic of the entire processing equipment is stronger, more conducive to long-term cyclic processing, and has a more professional processing level.

[0078] Furthermore, the lower mold assembly 2 includes a lower mold body 21 fixed on the top of the equipment platform 1, and a lower mold cavity 22 is opened on the top of the lower mold body 21, and the upper mold assembly 3 includes a connecting plate 31 slidably arranged on the outside of the first rotating shaft 4, and a support plate 32 is fixed at equal intervals on the outer edge of the connecting plate 31, and the bottom of the end of the support plate 32 is connected to a connecting plate 33, and the bottom of the connecting plate 33 is provided with an upper mold body 34 that cooperates with the lower mold cavity 22. When in use, after placing the cover plate to be processed into the interior of the lower mold cavity 22, the second driving assembly 6 can be used to drive the upper mold body 34 to descend, and then the cover plate to be processed in the lower mold cavity 22 is hot bent. Before this, the cover plate to be processed can be heated by the previous heating process, so that the cover plate can be hot bent after the upper mold body 34 and the lower mold cavity 22 cooperate to form a 3D vehicle-mounted display curved glass cover plate.

[0079] In addition, first grooves 23 are provided at the four corners of the top of the lower mold body 21, and the inner bottom end of the first groove 23 is connected to a spring 24, the top of the spring 24 is connected to a first magnet 25, and second grooves 35 corresponding to and aligned with the first grooves 23 are opened at the four corners of the bottom of the upper mold body 34, and the inner top of the second groove 35 is provided with a second magnet 36 corresponding to the first magnet 25, and the opposite surfaces of the first magnet 25 and the second magnet 36 are magnetically attracted to each other; when the upper mold body 34 and the lower mold body 21 correspond to each other up and down, the first magnet 25 set under the magnetic action of the second magnet 36 will drive the spring 24 to stretch and the first magnet 25 will be stuck in the inside of the second groove 35, so that after the upper mold body 34 and the lower mold body 21 are fitted together, the two have a better fitting effect, and the two will not be laterally offset, which is more conducive to the hot bending processing of the cover plate and improves the quality of the final product.

[0080] Furthermore, in this embodiment, an upper chamber 11 is provided inside the equipment platform 1, and the first driving assembly 5 includes a first mounting frame 51, a first rotating rod 52, an active disk 53, a first motor 54, a passive disk 55, a slot 551, a chassis 56 and a driving rod 57, wherein the first mounting frame 51 is fixedly mounted on the top of the equipment platform 1, and the first rotating rod 52 is vertically rotatably connected to the middle of the first mounting frame 51, the first motor 54 is mounted on the top of the first mounting frame 51, and the output end of the first motor 54 is connected to the first rotating rod 52. The active disk 53 is fixed to the bottom end of the first rotating rod 52, and the side of the active disk 53 has a first arc surface 531 and a second arc surface 532, the chassis 56 is fixed to the bottom of the active disk 53, and the driving rod 57 is fixed to the top of the chassis 56, and the passive disk 55 is fixed to the bottom end of the first rotating shaft 4, the card slot 551 is opened on the passive disk 55, and the number of the card slot 551 is the same as the number of the lower mold assembly 2, the driving rod 57 cooperates with the card slot 551, and the side of the passive disk 55 has a third arc surface 553.

[0081] When the first motor 54 is started by an external controller, the first motor 54 will drive the first rotating rod 52 to rotate, thereby causing the active disk 53, the chassis 56 and the driving rod 57 to rotate. When the driving rod 57 rotates, it cooperates with the slot 551, and the first curved surface 531, the second curved surface 532 and the third curved surface 553 cooperate with each other, thereby completing the driving of the passive disk 55 and the first rotating shaft 4. Since the number of the slots 551 is the same as the number of the lower mold assembly 2, when the active disk 53 rotates one circle, the passive disk 55 and the first rotating shaft 4 will rotate one-sixth of a circle, thereby allowing the upper mold assembly 3 to rotate at a precise angle. Similarly, the same is true when the first motor 54 drives the active disk 53 to return and rotate.

[0082] Furthermore, in the present embodiment, the second driving assembly 6 includes a bottom plate 61, a top plate 62, a second rotating rod 63, a threaded rod 64 and a threaded block 65, wherein the bottom plate 61 and the top plate 62 are respectively fixed to the bottom and top ends of the outside of the first rotating shaft 4, the number of the second rotating rod 63, the threaded rod 64 and the threaded block 65 is the same as the number of the upper mold assembly 3, and the second rotating rod 63 vertically penetrates the top plate 62 and is rotatably connected to the top plate 62, the top end of the threaded rod 64 is connected to the top end of the second rotating rod 63, and the bottom end of the threaded rod 64 is rotatably connected to the bottom plate 61, the threaded block 65 is threadedly connected to the outside of the threaded rod 64, and the outside of the threaded block 65 penetrates the bracket plate 32 and is fixed to the bracket plate 32.

[0083] At the same time, the second driving assembly 6 also includes a first gear 66, a second gear 67, a second mounting bracket 68 and a second motor 69, wherein the number of the first gears 66 is the same as the number of the first rotating rods 52, and the first gears 66 are sleeved on the outside of each first rotating rod 52 one by one, the second gear 67 is rotatably connected to the center of the top of the top plate 62, and the second gear 67 is meshed with the first gear 66, the second mounting bracket 68 is installed on the top of the top plate 62, the second motor 69 is installed on the top of the second mounting bracket 68, and the output end of the second motor 69 is connected to the top of one of the second rotating rods 63.

[0084] When the second motor 69 is started by the external controller, the second motor 69 can drive the first rotating rod 52 connected thereto to rotate, thereby causing the first gear 66 on the first rotating rod 52 to rotate. Since the first gear 66 is meshed with the second gear 67, when the second gear 67 rotates, the remaining first gears 66 will also rotate, thereby causing multiple second rotating rods 63 to drive the threaded rod 64 to rotate synchronously, so that multiple threaded blocks 65 can drive multiple upper mold assemblies 3 to rise or fall synchronously. On the one hand, only one second motor 69 is used to realize the common lifting and lowering of multiple upper mold assemblies 3, which is conducive to saving power resources, and the overall control is more uniform, which is convenient for management and subsequent adjustment. On the other hand, through the meshing between the first gear 66 and the second gear 67, the threaded connection between the threaded rod 64 and the threaded block 65 not only makes the lifting distance of the entire upper mold assembly 3 more accurate, but also has a self-locking structure after the upper mold assembly 3 is stopped, the overall use is more stable, and it is more conducive to subsequent hot bending processing and improves the processing effect.

[0085] Moreover, in the present embodiment, a toothed groove 311 is provided in the middle of the connecting disk 31, and a toothed bar 41 meshing with the toothed groove 311 is provided on the outside of the first rotating shaft 4, and the length of the toothed bar 41 is the same as the length of the threaded rod 64. The toothed bar 41 cooperates with the toothed groove 311, which can not only satisfy the rotation of the upper mold assembly 3 by the first driving component 5, but also guide the upper mold assembly 3 when the second driving component 6 drives the upper mold assembly 3 to rise and fall, so as to facilitate its movement to be more stable.

[0086] Furthermore, a connecting frame 26 is provided on the side of the lower mold body 21, and a connecting frame 27 is fixed in the middle of the connecting frame 26, one end of the connecting frame 27 close to the lower mold body 21 is fitted with the end surface of the lower mold body 21, and a first contact point 28 is provided on the top of the connecting frame 27, and a second contact point 37 cooperating with the first contact point 28 is provided at the bottom of the bracket plate 32, and a display light 38 is provided on the top of the bracket plate 32, and the first contact point 28, the second contact point 37 and the display light 38 are electrically connected. When the first contact point 28 and the second contact point 37 are in contact with each other, the circuit is connected and the display light 38 is always on. When the first contact point 28 and the second contact point 37 are separated from each other, the circuit is disconnected and the display light 38 is always off, so as to facilitate more intuitive positioning. Once the upper mold assembly 3 corresponds to the lower mold assembly 2 up and down, the display light 38 on the upper mold assembly 3 is not on, it is necessary to detect whether it is not aligned, so as to find the problem in time and ensure the subsequent hot pressing effect.

[0087] At the same time, in this embodiment, an arc box 7 is fixed to the top of the base plate 61, and a plurality of air heating tubes 73 are arranged inside the arc box 7, and a first arc cavity 29 is opened inside the lower mold body 21, and a second arc cavity 39 is opened inside the upper mold body 34, and the ends of the upper mold body 34 and the lower mold body 21 are both connected with a connecting hose 8, and the connecting hose 8 on the lower mold body 21 is connected to the interior of the first arc cavity 29, and the connecting hose 8 on the upper mold body 34 is connected to the interior of the second arc cavity 39, and the other ends of the plurality of connecting hoses 8 are all connected to the interior of the arc box 7. The interior of the arc box 7 is also rotatably connected to a plurality of second rotating shafts 71, and the number of the second rotating shafts 71 is the same as the number of the second rotating rods 63 and is aligned one by one. The top ends of the second rotating shafts 71 penetrate through the top of the arc box 7 and are sleeved with a third gear 74, and the outside of the second rotating shafts 71 is provided with fan blades 72 located inside the arc box 7, and the outside of the second rotating rod 63 is sleeved with a fourth gear 75 meshing with the third gear 74.

[0088] The air heating pipe 73 is arranged to heat the interior of the arc box 7. At the same time, under the action of the first connecting hose 8 and the second connecting hose 8, the interiors of the first arc cavity 29 and the second arc cavity 39 have a certain amount of heat, so that the temperature of the cover plate is always guaranteed when the upper mold body 34 and the lower mold body 21 are connected to each other, which is convenient for better hot bending. At the same time, when the second rotating rod 63 rotates, the engagement of the third gear 74 and the fourth gear 75 will cause the second rotating shaft 71 to rotate synchronously, and then the fan blades 72 will rotate. The rotation of the fan blades 72 can stir the internal air of the arc box 7, so that the temperature inside the first arc cavity 29 and the second arc cavity 39 is more uniform, which is more conducive to the insulation of the cover plate.

[0089] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
