For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0034] In one embodiment of the present utility model, referring to Figures 1-4 , a glass heating and cracking mechanism is provided, including a frame 100.
[0035] Among them, referring to Figures 1-4 , at least one heating and cracking device 200 is provided on the frame 100. A cracking table 300 is provided on the heating and cracking device 200. A blanking hole 310 penetrating up and down is formed on the cracking table 300. The cracking table 300 is used to carry the glass 400 after laser cutting. The surface of the glass 400 is divided into an inner glass block 410 and an outer glass block 420 along the cutting line 430. The heating and cracking device 200 is used to heat the outer glass block 420. The blanking hole 310 is used for the inner glass block 410 to be discharged after being separated from the outer glass block 420.
[0036] Compared with the prior art, at least one of the above one or more technical solutions in the glass heating and cracking mechanism provided by the embodiments of the present utility model has the following technical effects:
[0037] Referring to Figures 1-4 , during processing, the glass 400 after laser cutting is placed on the cracking table 300, so that the inner glass block 410 of the glass 400 is aligned with the blanking hole 310. The heating and cracking device 200 works to generate heat, and the heat is conducted to the outer glass block 420 of the glass 400 through the cracking table 300, thereby heating the outer glass block 420. The outer glass block 420 rapidly heats up. Under the tensile force generated by thermal expansion, the outer glass block 420 cracks along the cutting line 430 with the inner glass block 410, so that the inner glass block 410 and the outer glass block 420 are completely separated, and the inner glass block 410 is discharged from the blanking hole 310.
[0038] In addition, in the prior art, the hot water spray method is to spray hot water on the upper surface of the glass. Since the heat conduction coefficient of the glass 400 is low, the heat in the hot water is transferred from the upper surface of the glass to the lower surface of the glass, resulting in the temperature of the lower surface of the glass being much lower than that of the upper surface of the glass, and the gap formed by cracking along the cutting line 430 at the lower surface of the glass 400 is narrow. The narrow gap is not conducive to the separation of the inner glass block 410 and the outer glass block 420. Therefore, in this application, the heat is transferred from the lower surface of the outer glass block 420 to the outer glass block 420 from bottom to top through the splitting table 300. The lower surface of the outer glass block 420 is directly heated and has a higher temperature, so that the gap formed by cracking along the cutting line 430 at the lower surface of the glass 400 is wider. The wider gap helps the inner glass block 410 and the outer glass block 420 to be separated and fall quickly, with a high separation success rate and high efficiency.
[0039] Further, referring to Figures 2-4 , the heating and splitting device 200 includes a heating base 210 and a plurality of heating tubes 220 disposed in the heating base 210. Preferably, the plurality of heating tubes 220 are uniformly arranged in the heating base 210. The splitting table 300 is disposed on the heating base 210, and the heating base 210 is provided with a clearance hole 212 for avoiding the blanking hole 310. During processing, the plurality of heating tubes 220 work simultaneously to generate heat, making the heating base 210 and the splitting table 300 uniformly heat up. The splitting table 300 uniformly conducts the heat to the outer glass block 420 of the glass 400, thereby heating the outer glass block 420. Compared with the prior art method of heating the glass 400 by hot water spray, the above method of heating the outer glass block 420 is more stable and the heat is more uniform, making the outer glass block 420 uniformly heated, with good separation integrity and a high separation success rate.
[0040] Among them, referring to Figure 2 and Figure 3 , the heating base 210 and the splitting table 300 can be an integral structure or a combined structure, which is not limited herein.
[0041] Further, referring to Figure 2 and Figure 3 , a plurality of mounting holes 211 are provided on the peripheral side walls of the heating base 210, and each heating tube 220 is respectively mounted in a mounting hole 211. Among them, the heating tube 220 can be fixedly mounted in the mounting hole 211 by means of bonding or clamping, etc., which is convenient for installing the heating tube 220. Preferably, the mounting holes 211 are horizontally arranged on the heating base 210, that is, the heating tubes 220 are horizontally mounted on the heating base 210, so that the plurality of heating tubes 220 can make the heating base 210 and the splitting table 300 heat up quickly during operation, and the heating effect is good.
[0042] Further, referring to Figure 2 and Figure 3, the multiple heating tubes 220 are divided into multiple groups, and two adjacent groups of heating tubes 220 are arranged at different heights on the heating base 210 and cross each other, avoiding conflicts in the installation of the two groups of heating tubes 220 and having a compact structure.
[0043] Among them, referring to Figure 3 , the heating tube 220 can be an electric heating tube or an electric heating wire, which is not limited herein.
[0044] Among them, the shapes of the inner glass block 410 and the outer glass block 420 on the glass 400 referred to in this application can be of any shape, depending on actual production requirements.
[0045] Furthermore, referring to Figure 2 and Figure 3 , the heating and splitting device 200 further includes a temperature sensor 230. The temperature sensor 230 is arranged on the heating base 210 and is used to detect the temperature of the heating base 210, so that the temperature of the heating base 210 is at a set temperature, avoiding the temperature of the heating base 210 being too high or too low and having a reliable structure. Among them, the temperature sensor 230 is a mature existing technology, and its structure and working principle will not be elaborated herein.
[0046] Preferably, referring to Figure 2 and Figure 3 , the heating base 210 is an aluminum base, and the splitting table 300 is an aluminum plate. Since aluminum is a metal with high thermal conductivity, the aluminum base and the aluminum plate can quickly conduct the heat generated by the heating tube 220 to the outer glass block 420 of the glass 400, thereby quickly heating the outer glass block 420 with high efficiency.
[0047] Furthermore, referring to Figure 2 and Figure 3 , the heating base 210 is fixedly installed on the frame 100 through a plurality of connecting pieces 240. The upper end of the connecting piece 240 is fixedly connected to the heating base 210 through a plurality of screws, and the lower end of the connecting piece 240 is fixedly connected to the frame 100 through a plurality of screws, which is convenient for installation.
[0048] In another embodiment, referring to Figure 1 , the frame 100 is provided with a first positioning member 110 and a second positioning member 120. The first positioning member 110 and the second positioning member 120 are used to respectively abut against two adjacent side walls of the glass 400, so that the glass 400 is positioned and placed on the splitting table 300, and the inner glass block 410 of the glass 400 is aligned with the blanking hole 310, so that the subsequent heating and splitting device 200 can accurately heat the outer glass block 420 of the glass 400. Among them, both the first positioning member 110 and the second positioning member 120 are fixedly installed on the frame 100 through a support frame 130.
[0049] Furthermore, referring to Figure 1, below the blanking hole 310 of the frame 100, there is a blanking guiding groove 320, and the blanking guiding groove 320 is used to guide and collect the inner glass blocks 410 falling from the blanking hole 310 in a specified direction. For example, a collection box is placed at the lower end of the blanking guiding groove 320, so as to collect the inner glass blocks 410 in the collection box for subsequent centralized processing of the inner glass blocks 410.
[0050] Further, the contour shape of the blanking hole 310 is consistent with the contour shape of the inner glass block 410, and the area of the surface of the blanking hole 310 is slightly larger than the area of the inner glass block 410, which helps the inner glass block 410 to quickly fall from the blanking hole 310.
[0051] In another embodiment, above the splitting table 300 of the frame 100, there is a cylinder pressing-down assembly, and the cylinder pressing-down assembly is used to apply pressure to the inner glass block 410. The cylinder pressing-down assembly includes a cylinder and a pressing block. The cylinder is fixedly installed on the frame 100 through a bracket, the telescopic rod of the cylinder is arranged vertically downward, the pressing block is fixedly installed at the lower end of the telescopic rod of the cylinder, and the pressing block is located above the blanking hole 310. During operation, the heating and splitting device 200 works to generate heat, and the heat is conducted to the outer glass block 420 of the glass 400 through the splitting table 300, so that the outer glass block 420 is quickly heated. Under the action of the tensile force generated by thermal expansion, the outer glass block 420 cracks along the cutting line 430 with the inner glass block 410. At the same time, the cylinder drives the pressing block to move downward to press against the upper surface of the inner glass block 410 and apply pressure to the inner glass block 410. Under the dual action of the tensile force generated by thermal expansion and the thrust applied by the cylinder pressing-down assembly, the inner glass block 410 is quickly separated from the outer glass block 420, improving the splitting efficiency.
[0052] In another embodiment, referring to Figure 1 , two heating and splitting devices 200 are symmetrically arranged on the frame 100, and the two heating and splitting devices 200 are respectively used to split two pieces of glass 400, improving the processing efficiency.
[0053] Among them, referring to Figure 1 , the glass heating and splitting mechanism includes an electric control box 500. The heating tube 220 and the temperature sensor 230 of the heating and splitting device 200 are both electrically connected to the electric control box 500 through cables, and the cylinder pressing-down assembly is electrically connected to the electric control box 500. In this embodiment, the electric control box 500 can be set by using a PLC or an integrated chip according to actual production needs. Since the electric control box 500 belongs to a technology that is formed and mature in the prior art, how the electric control box 500 controls the operation of the glass heating and splitting mechanism should be well known and mastered by those skilled in the art. Therefore, the control principle of the present invention will not be elaborated herein.
[0054] In another embodiment, referring to Figure 1 and Figure 5The first positioning member 110 and the second positioning member 120 are both fixedly mounted on a telescopic rod of an electric cylinder 140, and the electric cylinder 140 is horizontally fixedly mounted on the frame 100. One electric cylinder 140 is used to drive the first positioning member 110 to move along the X direction, thereby adjusting the horizontal position of the first positioning member 110 along the X direction, and the other electric cylinder 140 drives the second positioning member 120 to move along the Y direction, thereby adjusting the horizontal position of the second positioning member 120 along the Y direction, so that the first positioning member 110 and the second positioning member 120 can position the glass 400 of different lengths and widths, so that the glass 400 can be accurately placed on the splitting table 300, and the applicability is high.
[0055] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.
[0056] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, its architecture can be flexible and can derive a series of products.
