Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, and in particular to hot pressing equipment and a method for processing a vehicle-mounted glass cover plate. Background Art

[0002] Glass is used to block wind and transmit light. After certain special treatments, the glass has better performance. Among them, the use of automotive glass is more common. Automotive glass includes glass cover plates, car windows, etc. When processing automotive glass cover plates, the glass is first heated, and then the heated glass is transported to the hot pressing equipment for hot pressing treatment.

[0003] The existing hot pressing equipment for glass uses a hot press. After the heated glass enters the hot press, it is conveyed to the mold of the hot press through a conveyor chain. The glass is flat as a whole. After being heated at high temperature, due to thermal expansion, the outer edge of the glass has a slight expansion and warping shape. Since the mold at the bottom is the shape of the bent glass, the hot press acts downward on the surface of the heated glass and bends it along the mold. The first force received by the heated glass is on the bent part of the glass, which can easily cause the outer edge of the glass to warp. During the initial heating, the glass has already slightly expanded and warped, which can easily cause uneven pressure on the outer side of the glass and the mold, and the heat on the glass cannot be dissipated in time. The existing hot pressing equipment directly and completely acts on the glass, which can easily cause the glass to crack during hot pressing. For this reason, we propose a hot pressing equipment and method for processing automotive glass cover panels. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-11 The present invention provides a technical solution: a hot pressing device for processing vehicle-mounted glass cover plates, which is designed to include a hot pressing box body 1 and a conveyor chain 2. The hot pressing box body 1 is provided with a material guide slope 11, and the hot pressing box body 1 is provided with a visual window 12. The conveyor chain 2 is an existing chain design, and its front end is connected to the glass heating furnace, and the rear end is connected to the glass cooling and placement area. The entire conveyor chain 2 is not fully drawn in the accompanying drawings. A hot pressing tank body 21 is provided at one end of the conveyor chain 2 in the hot pressing box body 1, and a hot pressing module is provided at the hot pressing tank body 21. The hot pressing module includes an upper module 3 and a lower module 4. The upper module 3 and the lower module 4 are bendable and deformable. The design of the hot pressing tank body 21 is conducive to providing space for the upper module 3 and the lower module 4 to be released when bending and deforming.

[0037] The design of lower module 4 is as shown in the attached Figure 5 and attached Figure 6 As shown in the figure, it includes multiple lower mold rollers 41 with the same height as the conveying rollers of the conveyor chain 2. The lower mold rollers 41 are of a cylindrical structure as a whole. Therefore, after the glass enters the hot press box 1 through the conveyor chain 2, it is continuously rolled in. A positioning camera 5 is provided in the middle part of the lower mold group 4. When the glass is conveyed to the middle position, the positioning camera 5 detects the center line position of the glass, which means that the glass is completely conveyed to the lower mold roller 41.

[0038] The two ends of the lower mold roller 41 are equipped with lower mounting plates 42, and the two adjacent lower mounting plates 42 are connected by hinge plates 43. Two groups of stabilizing bracket groups are installed on the lower mounting plates 42, and the stabilizing bracket groups are symmetrically distributed about the positioning camera 5. The stabilizing bracket group includes a connecting rod 46, and the two ends of the connecting rod 46 are connected to the lower mounting plate 42. The lower mounting plate 42 is provided with a strip groove 47. The two ends of the connecting rod 46 are respectively connected to a strip plate 48, and the strip plate 48 is connected to a slide column 49 that slides in the strip groove 47. In this way, after the glass is completely transported to the lower mold roller 41, it is opened from the middle position of the lower mold group 4 to both sides, and the slide column 49 slides along the strip groove 47, thereby allowing the adjacent lower mounting plates 42 to rotate and adjust the angle at the connection position of the hinge plate 43. The hinge plates 43 are designed as arc segments and are staggered and stacked with each other, so that the angle of a single lower mold roller 41 can be adjusted until the lower mold group 4 is bent into the shape required for the glass, as shown in the attached figure. Figure 5 As shown in , the bending deformation of the lower mold 4 is stopped. At this time, the upper mold 3 needs to bend and deform, and press down to the upper position of the glass. Through the cooperation of the upper mold 3 and the lower mold 4, the glass is hot-pressed and bent.

[0039] The design of upper module 3 is as shown in the attached Figure 7 As shown in the figure, it includes multiple upper mold rollers 31 that cooperate with the lower mold roller 41, and upper mounting plates 32 are installed at both ends of the upper mold roller 31. Two adjacent upper mounting plates 32 are connected by a hinge plate 43. There is a cavity inside the upper mold roller 31, and cooling air holes 33 are provided at the contact point between the upper mold roller 31 and the lower mold roller 41.

[0040] After the upper mold assembly 3 and the lower mold assembly 4 cooperate with each other to form the glass into the desired bending shape, the glass needs to be cooled simultaneously.

[0041] To cool the lower part of the glass, a heat dissipation chamber 44 is opened on the lower mold roller 41, and heat dissipation holes 45 are opened at both ends of the heat dissipation chamber 44. A heat-receiving part 6 is provided in the heat dissipation chamber 44, and the heat-receiving part 6 is heated to discharge the air in the heat dissipation chamber 44 to the heat dissipation holes 45; the heat-receiving part 6 includes a temperature-sensitive arc-shaped piece 61 arranged at the top of the heat dissipation chamber 44, and a group of sliding pieces 62 are provided in the heat dissipation chamber 44, and the two sliding pieces 62 have opposite magnetism, and a spring 63 is connected between the two sliding pieces 62.

[0042] After the bottom of the glass is bent and fits the temperature-sensitive curved piece 61, the temperature between the two sliding pieces 62 increases, and the air pressure between the two increases. When the gas pressure is greater than the magnetic attraction of the two sliding pieces 62, the two sliding pieces 62 slide to both sides, and the air in the heat dissipation chamber 44 is discharged from the heat dissipation holes 45, thereby cooling the glass. After the air is discharged, the tension of the spring 63 increases, causing the two sliding pieces 62 to be pulled back. This is repeated, so that the bottom of the glass can be cooled according to the real-time temperature of the glass during the deformation process.

[0043] For cooling the top of the glass, a power assembly 7 is installed in the hot press box 1 to drive the lower mold 4 and the upper mold 3 to wrap the glass, and a cooling assembly 8 is provided at the hot press box 1 to introduce cold air into the cavity of the upper mold roller 31. The cooling assembly 8 includes a cooling pump body 81 installed on the top of the hot press box 1. The cooling pump body 81 is connected to an output pipe 82, and the output pipe 82 is connected to two centralized pipes 83, and the centralized pipe 83 is connected to a plurality of branch pipes 84, the branch pipes 84 are connected to the cavity of the upper mold roller 31, and the cooling gas is continuously pumped out by the cooling pump body 81. The cooling gas is sequentially divided from the output pipe 82 and the centralized pipe 83 to the plurality of branch pipes 84, and the cooling gas is continuously introduced into the cavity of the upper mold roller 31 by the branch pipes 84, and then the cooling gas is blown out from the cooling air holes 33 to the top of the glass, thereby cooling the top of the glass.

[0044] The bending and deformation of the upper mold assembly 3 and the lower mold assembly 4 into the glass shape is adjusted by using the power assembly 7.

[0045] The power assembly 7 includes a first mounting plate 71 and a second mounting plate 72. The top of the first mounting plate 71 is connected to a mounting bracket 73, and the mounting bracket 73 is connected to the side wall of the hot pressing box body 1. The top of the second mounting plate 72 is connected to a telescopic rod 74, and the telescopic rod 74 is connected to the inner wall of the hot pressing box body 1. The two ends of the first mounting plate 71 are connected to first hydraulic rods 75, and the two first hydraulic rods 75 are respectively connected to the lower mounting plate 42 at the two ends of the lower mold group 4. The two ends of the second mounting plate 72 are connected to second hydraulic rods 76, and the second hydraulic rods 76 are respectively connected to the upper mounting plate 32 at the two ends of the upper mold group 3. The length of the first hydraulic rod 75 is greater than that of the second hydraulic rod 76.

[0046] Two winding motors 77 are connected to the outer wall of the hot press box body 1, and a roller 78 is connected to the output shaft of the winding motor 77. The roller 78 passes through the inner wall of the hot press box body 1. Two winding wheels 79 are connected to the roller 78, and a steel wire rope 791 is wound on the winding wheel 79. The steel wire rope 791 is installed on the upper mounting plate 32 at both ends of the upper module 3.

[0047] At the beginning, the lower mold roller 41 on the lower mold group 4 is at the same height as the roller of the conveyor chain 2. After the glass continues to enter, until the positioning camera 5 detects the center line position of the glass, because the glass is in a plate shape when it is not deformed, the positioning camera 5 completely captures the glass. After the center line of the glass enters the positioning camera 5, the first hydraulic rod 75 and the second hydraulic rod 76 are started at the same time. After the first hydraulic rod 75 contracts, it starts to reel and adjust from the two end positions of the lower mold group 4. The second hydraulic rod 76 also drives the upper mold group 3 to reel and adjust, and the reeling motor 77 starts to rotate, so that the wire rope 791 is released until the upper mold group 3 is attached to the glass surface. The first hydraulic rod 75 and the second hydraulic rod 76 are continuously retracted. This avoids applying pressure to the glass at one time, facilitates the release of the stress after the glass is heated, and is beneficial to the hot pressing of the glass.

[0048] After the hot pressing is completed, the lower mold 4 is provided with a swing chamber 9 at one end of the heat dissipation chamber 44, and a swing groove 91 is opened on the top of the swing chamber 9. A swing motor 92 is installed in the swing chamber 9, and the output shaft of the swing motor 92 is connected to a swing plate 93 passing through the swing groove 91. The swing plate 93 is driven by the swing motor 92 to swing, thereby transporting the glass out of the hot pressing box 1.

[0049] A hot pressing method for processing a vehicle glass cover plate comprises the following steps:

[0050] A: Heat transportation of heated glass: the heated glass is transported to the hot pressing box 1 through the conveyor chain 2.

[0051] B: Glass positioning, positioning camera 5 determines the center position of the glass.

[0052] C: Wrapping the heated glass: the power assembly 7 lifts the lower module 4 and the upper module 3 to wrap the heated glass.

[0053] D: Heat dissipation at the bottom of the glass. The heated element 6 discharges the air in the heat dissipation chamber 44 to the heat dissipation holes 45 to dissipate heat at the bottom of the glass.

[0054] E: Heat dissipation from the top of the glass: the cooling assembly 8 introduces cold air into the cavity of the upper mold roller 31 to dissipate heat from the top of the glass.

[0055] F: After the hot pressing is completed, the power assembly 7 lifts the upper module 3 and the glass is hot pressed into shape.

[0056] The present embodiment provides a hot pressing device and method for processing vehicle-mounted glass cover plates. Compared with the prior art, by providing a bendable upper module and a lower module, after the positioning camera detects the center position of the glass, the upper module and the lower module are driven by the provided power component to wrap the glass and bend it gradually from the center position of the glass to the sides, thereby avoiding the hot pressing deformation force first acting on the position of the glass that expands due to high temperature. The heat dissipation chamber of the lower module is used to receive the heat from the bottom of the glass, and the bottom of the glass is quickly dissipated. The cooling component cools the top position of the glass in the upper module, which is beneficial to corresponding cooling of the top and bottom of the glass during the hot bending process, avoiding the problem of glass cracking caused by untimely heat dissipation during the hot pressing process. The swing chamber provided in the present embodiment is swung by a swing motor, which is beneficial to transporting the glass out after it is formed.
