Description

Technical Field

[0001] The utility model relates to the technical field of ultra-thin glass processing, in particular to an ultra-thin glass hot drawing and thinning machine. Background Art

[0002] Ultra-thin glass refers to glass with a thickness of 0.1-1.1mm. It has the advantages of high light transmittance, smooth surface, high hardness, good chemical stability, and a wide range of applications. It is widely used in the electronics industry, especially the information industry. At present, the industry mainly uses the float process to process ultra-thin glass. Specifically, the molten glass liquid is continuously flowed from the melting furnace into a milling groove filled with protective gas (N2 and H2) so that the glass liquid floats on the surface of the metal tin liquid. After flattening and polishing, it forms a glass with uniform thickness and two parallel and flat surfaces. However, the above float process can only be used to produce glass with a thickness of 0.55-25mm. For ultra-thin glass with a thickness of less than 0.55mm, mechanical processing or chemical etching is required to further thin the glass sheet. Mechanical thinning methods include flat grinding and CNC carving. Chemical etching mainly uses hydrofluoric acid to corrode and thin the glass surface. When the above methods are used to further thin the glass, most of the material on the glass surface needs to be removed to obtain the ultra-thin glass of the required thickness, which will cause a large amount of material waste and increase the production cost of ultra-thin glass.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Please combine Figure 1-5The utility model discloses an ultra-thin glass hot drawing and thinning machine 10 with less material waste and low production cost. The ultra-thin glass hot drawing and thinning machine 10 includes an equipment frame 100, a feeding component 200, a softening heater 300, a rolling component 400, a tempering heater 500 and a controller 600. The inner cavity of the equipment frame 100 is provided with a softening zone 110, a rolling zone 120, a tempering zone 130 and a cooling zone 140 connected in sequence from top to bottom. A feed port (not shown) connected to the softening zone 110 is opened on the upper top surface or side surface of the equipment frame 100, and a discharge port 150 connected to the cooling zone 140 is opened on the lower bottom surface or side surface of the equipment frame 100. The feed assembly 200 includes at least one pair of feed rollers located outside the equipment frame 100 and corresponding to the feed port. Each pair of feed rollers includes a first roller 210 and a second roller 220, which are positioned opposite each other and rotatably mounted on the outer wall of the equipment frame 100. A first passage 230 is formed between the first roller 210 and the second roller 220 for passing the glass sheet 20 to be thinned. The width of the first passage 230 (the width of the gap between the first roller 210 and the second roller 220) is the same as the thickness of the glass sheet 20 to be thinned. The feed assembly 200 also includes a first motor 240 fixed to the outer wall of the equipment frame 100 and used to drive the at least one first roller 210 to rotate. The softening heater 300 is housed within the softening zone 110 and fixedly connected to the inner wall of the equipment frame 100. A first heating chamber 310 is provided within the softening heater 300 for primary heating of the glass sheet 20. The softening heater 300 is provided with a first heating inlet 320 communicating with the first heating chamber 310 and the first connecting passage 230, and a first heating outlet 330 adjacent to the calendering zone 120 and communicating with the first heating chamber 310. The calendering assembly 400 includes at least one pair of calendering rollers housed within the calendering zone 120. Each pair of calendering rollers includes a third roller 410 and a fourth roller 420 disposed opposite each other and rotatably mounted on the inner wall of the equipment frame 100. A second connecting passage 430 is formed between the third roller 410 and the fourth roller 420, communicating with the first heating outlet 330. The width of the second connecting passage 430 (the width of the gap between the third roller 410 and the fourth roller 420) is equal to the target thickness of the glass sheet 20 after thinning. The rolling assembly 400 also includes a second motor 440 fixed to the inner wall of the equipment frame 100 and configured to rotate the at least one third roller 410. A tempering heater 500 is housed within the tempering zone 130 and fixedly connected to the inner wall of the equipment frame 100. The tempering heater 500 includes a second heating chamber 510 for secondary heating the glass sheet 20. The tempering heater 500 also includes a second heating inlet 520 communicating with the second heating chamber 510 and the second through-channel 430, and a second heating outlet 530 communicating with the cooling zone 140 and the second heating chamber 510.The controller 600 is located outside the equipment frame 100 and is fixedly connected to the equipment frame 100. The controller 600 is electrically connected to the softening heater 300, the tempering heater 500, the first motor 240 and the second motor 440 to control the operation of the entire machine.

[0027] During operation of the ultra-thin glass hot-drawing and thinning machine 10, an operator inserts the glass sheet 20 to be thinned into the first passage 230 between the first roller 210 and the second roller 220 and activates the first motor 240, the softening heater 300, the second motor 440, and the tempering heater 500. The first motor 240 drives the first roller 210 to roll relative to the glass sheet 20. The rolling friction between the first roller 210 and the glass sheet 20 drives the glass sheet 20 toward the softening zone 110. During this process, the second roller 220, under the influence of the glass sheet 20, rolls synchronously with the first roller 210, thereby jointly driving the movement of the glass sheet 20. The glass sheet 20 enters the first heating chamber 310 through the first heating inlet 320 of the softening heater 300 and is heated and softened within the first heating chamber 310. The softened glass sheet 20 enters the rolling zone 120 through the first heating outlet 330 and is inserted into the second connecting channel 430 between the third roller 410 and the fourth roller 420. Because the second motor 440 drives the third roller 410 to rotate, and the width of the second connecting channel 430 is the same as the target thickness of the glass sheet 20 after thinning, the third roller 410 drives the softened glass sheet 20 further toward the tempering zone 130. Simultaneously, the fourth roller 420 rolls relative to the glass sheet 20 under the influence of the glass sheet 20. In this way, the third roller 410 and the fourth roller 420 jointly drive the glass sheet 20 to move, and the third roller 410 and the fourth roller 420 also work together to squeeze the softened glass sheet 20, thereby rolling the glass sheet 20 and reducing its thickness. Driven by the third roller 410 and the fourth roller 420, the thinned glass sheet 20 enters the tempering zone 130 and enters the second heating chamber 510 through the second heating inlet 520 for tempering heating. The tempered glass sheet 20 then enters the cooling zone 140 through the second heating outlet 530, where it is cooled and discharged. Depending on the cooling speed required for the ultra-thin glass, a corresponding cooling device may be provided in the cooling zone 140 to achieve rapid cooling of the ultra-thin glass. For example, a fan may be provided in the cooling zone 140 to accelerate the cooling of the ultra-thin glass. Alternatively, the ultra-thin glass may be allowed to cool naturally at room temperature in the cooling zone 140. It should be noted that tempering the thinned glass sheet 20 eliminates internal stress in the glass sheet 20, thereby improving the mechanical strength of the ultra-thin glass. In this embodiment, the heating temperature of the softening heater 300 is 900°C, the heating temperature of the tempering heater 500 is 600°C, and the ultra-thin glass hot drawing and thinning machine 10 can thin the incoming glass sheet 20 with a thickness of 3-6 mm to 0.15-0.3 mm. Its operating speed can reach 6-12 m / min, thereby improving the processing efficiency of ultra-thin glass.

[0028] The above-mentioned ultra-thin glass hot-drawing and thinning machine 10 thins the glass sheet 20 to a preset thickness by preheating and softening the glass sheet 20 and then rolling it. The thinned glass sheet 20 is then tempered and heated to enhance the glass strength, thereby obtaining ultra-thin glass with mechanical strength that meets the requirements of use. During the processing, the thickness of the glass sheet 20 is thinned while its length is increased. The overall volume of the glass sheet 20 remains unchanged, and there is no material waste. This can avoid the problem of glass material loss caused by mechanical thinning or chemical etching, thereby reducing the production cost of ultra-thin glass.

[0029] The equipment frame 100 is used to support the remaining components and provides a work area for thinning the glass sheet 20. In this embodiment, the top surface of the equipment frame 100 is provided with a material inlet, and the lower side surface of the equipment frame 100 is provided with a material outlet 150, so that material can be loaded from the top of the equipment frame 100 and discharged from the lower side of the equipment frame 100. When the ultra-thin glass hot-drawing and thinning machine 10 is mounted on an external bracket, material can also be loaded from the upper side of the equipment frame 100 and discharged from the bottom of the equipment frame 100. In one embodiment, the equipment frame 100 includes a frame 160 forming a receiving cavity therein, and a first partition 170, a second partition 180, and a third partition 190 disposed within the receiving cavity and fixedly connected to the frame 160. The bottom of the frame 160 is provided with support legs 161 to elevate the bottom of the frame 160 to facilitate the removal of ultra-thin glass or to provide a corresponding glass transfer mechanism to prevent the ultra-thin glass from falling and being damaged during delivery. The first partition 170, the second partition 180 and the third partition 190 are arranged in parallel from top to bottom in the receiving chamber to separate the receiving chamber into a softening zone 110, a calendering zone 120, a tempering zone 130 and a cooling zone 140. The top surface of the frame 160 is provided with a feed port, the lower side surface of the frame 160 is provided with a discharge port 150, the feed roller is rotatably mounted on the top surface of the outer wall of the frame 160, the softening heater 300 is fixed on the first partition 170, the calendering roller is rotatably mounted on the second partition 180, and the tempering heater 500 is fixed on the third partition. The first partition plate 170 is provided with a first through-hole located directly below the first heating outlet 330, the second partition plate 180 is provided with a second through-hole located directly below the second connecting channel 430, and the third partition plate 190 is provided with a third through-hole located directly below the second heating outlet 530. The center of the first through-hole, the center of the second through-hole, and the center of the third through-hole are connected by a straight line extending in the vertical direction. This prevents the glass sheet 20 from colliding with the frame 160 or the partition plate during transportation, thereby reducing damage to the glass sheet 20 and lowering the product defect rate. Furthermore, in this embodiment, the softening zone 110, the rolling zone 120, the tempering zone 130, and the cooling zone 140 are arranged in sequence from top to bottom in the vertical direction. During the transportation of the glass sheet 20, the gravity of the glass sheet 20 provides auxiliary power for glass movement and rolling deformation, thereby reducing the difficulty of the glass sheet 20 thinning operation.

[0030] The feeding assembly 200 is used to feed the glass sheet 20 to be thinned into the interior of the ultra-thin glass hot-drawing and thinning machine 10; the rolling assembly 400 is used to roll the heated and softened glass sheet 20 to obtain a glass sheet 20 of a specific thickness, thereby thinning the glass sheet 20. Figure 1-5 A first driven wheel 250 is fixed to the end of the first roller 210, and a first driving wheel 260 is fixed to the output shaft of the first motor 240; the first driving wheel 260 and the first driven wheel 250 are both gears, and the first driving wheel 260 and the first driven wheel 250 are meshed for transmission, or the first driving wheel 260 and the first driven wheel 250 are driven by a toothed power transmission belt; or the first driving wheel 260 and the first driven wheel 250 are both pulleys, and the first driving wheel 260 and the first driven wheel 250 are driven by a transmission belt; or the first driving wheel 260 and the first driven wheel 250 are both sprockets, and the first driving wheel 260 and the first driven wheel 250 are driven by a chain. Preferably, in this embodiment, the first driving wheel 260 and the first driven wheel 250 are both pulleys, and the first driving wheel 260 and the first driven wheel 250 are driven by a first transmission belt 270. The feeding assembly 200 also includes a first mounting frame 280. The first mounting frame 280 has a U-shaped structure and is fixed to the top surface of the frame body 160. The first mounting frame 280 includes two first lugs arranged opposite to each other and a first connecting plate fixed to the bottom of the two first lugs. The first connecting plate is fixedly connected to the top surface of the frame body 160. For example, the first connecting plate is screwed to the top surface of the frame body 160 or welded to the top surface of the frame body 160. The first connecting plate and the two first lugs together form a first rotation mounting area. The first roller 210 and the second roller 220 are both accommodated in the first rotation mounting area and are both rotatably connected to the two first lugs. It should be noted that in this embodiment, another first roller 210 is provided above the first roller 210 in the first rotation mounting area and is rotatably connected to the two first lugs. Furthermore, another second roller 220 is provided above the second roller 220 and is rotatably connected to the two first lugs. In other words, the feed assembly 200 actually includes two pairs of feed rollers. By increasing the number of feed rollers, support for the incoming glass sheet 20 can be achieved, thereby preventing the incoming glass sheet 20 from being overloaded and broken. Of course, the number of feed rollers can be further increased as needed, which will not be further explained here.

[0031] Similarly, a second driven wheel 450 is fixed to the end of the third roller 410, and a second driving wheel 460 is fixed to the output shaft of the second motor 440; the second driving wheel 460 and the second driven wheel 450 are both gears, and the second driving wheel 460 and the second driven wheel 450 are meshed for transmission, or the second driving wheel 460 and the second driven wheel 450 are driven by a toothed power transmission belt; or the second driving wheel 460 and the second driven wheel 450 are both pulleys, and the second driving wheel 460 and the second driven wheel 450 are driven by a transmission belt; or the second driving wheel 460 and the second driven wheel 450 are both sprockets, and the second driving wheel 460 and the second driven wheel 450 are driven by a chain. Preferably, in this embodiment, the second driving wheel 460 and the second driven wheel 450 are both pulleys, and the second driving wheel 460 and the second driven wheel 450 are driven by a second transmission belt 470. The calendering assembly 400 also includes a second mounting frame 480, and the second mounting frame 480 is a U-shaped structure and is fixed on the second partition 180. The second mounting frame 480 includes two second lugs arranged opposite to each other and a second connecting plate fixed at the bottom of the two second lugs. The second connecting plate is fixedly connected to the second partition 180. For example, the second connecting plate is screwed to the second partition 180 or welded to the second partition 180. The second connecting plate and the two second lugs together form a second rotation mounting area. The second roller 220 and the second roller 220 are both accommodated in the second rotation mounting area and are both rotatably connected to the two second lugs.

[0032] The softening heater 300 is used to heat and soften the glass sheet 20, thereby making it ductile and facilitating hot drawing and rolling. The tempering heater 500 is used to temper the thinned glass sheet 20 to enhance its mechanical strength. In this embodiment, the softening heater 300 and the tempering heater 500 have the same structure, differing primarily in the temperature at which they heat the glass sheet 20. Both the first heating chamber 310 and the second heating chamber 510 are equipped with a heating mechanism, which can be an electric heating wire or a thick film heater disposed on the inner walls of the first heating chamber 310 and the second heating chamber 510.

[0033] In one embodiment, the ultra-thin glass hot-drawing and thinning machine 10 further includes a material guide and clamping assembly 700 housed within the calendering zone 120. The material guide and clamping assembly 700 includes a first clamping plate 710 and a second clamping plate 720 suspended above the calendering rollers and disposed opposite each other, and a telescopic drive member 730 fixed to the inner wall of the equipment frame 100. A third passage 740 is formed between the first clamping plate 710 and the second clamping plate 720, which communicates with the second passage 430 and the first heating outlet 330 and allows glass to pass through. The telescopic drive member 730 is drivably connected to the first clamping plate 710 and / or the second clamping plate 720 to adjust the width of the third passage 740. Further preferably, the telescopic drive member 730 is an electric push rod, a pneumatic push rod, or a pneumatic clamp; or the telescopic drive member 730 includes a servo motor, a screw drivenly connected to the output shaft of the servo motor and coaxially rotating therewith, and a nut sleeved on the screw and threadedly connected thereto, the nut being drivably connected to the first clamping plate 710 or the second clamping plate 720. Preferably, the telescopic drive member 730 is a pneumatic clamp. By providing the guide and clamping assembly 700, the softened glass sheet 20 can be guided and supported, allowing the softened glass sheet 20 to accurately enter between the third roller 410 and the fourth roller 420 for rolling. This prevents the softened glass sheet 20 from collapsing and deforming during movement, ensuring the normal rolling of the glass sheet 20. By adjusting the width of the third connecting channel 740 through the telescopic drive member 730, the first and second clamping plates 710, 720 can be aligned with the glass sheet 20, achieving pre-rolling of the softened glass. This reduces the thickness of the glass sheet 20 in one step, reducing the difficulty of the glass sheet 20 entering between the third and fourth rollers 410, 420 for secondary rolling and thinning. In addition, in this embodiment, a surface of the first plate 710 located in the third connecting channel 740 and a surface of the second plate 720 located in the third connecting channel 740 are both provided with a high temperature resistant cushion layer to extend the service life of the first plate 710 and the second plate 720.

[0034] The ultra-thin glass hot-drawing and thinning machine 10 also includes a protective cover 800, which is located outside the equipment frame 100 and covers the feed rollers. The protective cover 800 is fixedly connected to the top surface of the equipment frame 100, and a through-hole 810 is formed on the side of the protective cover 800 facing away from the equipment frame 100, which communicates with the inner cavity of the protective cover 800. The protective cover 800 protects the feed assembly 200, preventing damage to the feed assembly 200 from external impacts and thus extending the service life of the feed assembly 200. Similarly, a partition is also provided on the side of the frame 160 to separate the operating area of the ultra-thin glass hot-drawing and thinning machine 10 from the external environment, preventing external objects from impacting or damaging the components within the ultra-thin glass hot-drawing and thinning machine 10. It should be noted that when partitions are provided on the side of the frame 160, at least the partition on one side of the frame 160 is a transparent plate, allowing operators to observe the internal working conditions of the frame 160.

[0035] In one embodiment, the ultra-thin glass hot-drawing and thinning machine 10 further includes a control panel 900, which is fixed to the outer wall of the equipment frame 100 and electrically connected to the controller 600. Thus, an operator can adjust the operating parameters of the first motor 240, the second motor 440, the softening heater 300, and the tempering heater 500 by operating the control panel 900, and simultaneously control the start and stop of the ultra-thin glass hot-drawing and thinning machine 10. Furthermore, the ultra-thin glass hot-drawing and thinning machine 10 further includes an audible and visual alarm 910, which is disposed on the outer side of the equipment frame 100 and electrically connected to the controller 600. The audible and visual alarm 910 is mounted on the control panel 900. When there is a lack of incoming material at the feed assembly 200 or when the ultra-thin glass hot-drawing and thinning machine 10 malfunctions, the controller 600 controls the audible and visual alarm 910 to activate, allowing operators to promptly respond to equipment abnormalities.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily.
