Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass processing, and in particular to a positioning rack and a glass processing positioning device for glass processing. Background Technology
[0002] Existing laminated glass typically consists of a first layer, a second layer, and a third layer. The first layer is larger than the second layer, the second layer is positioned in the center of the first layer, and the third layer is positioned between the first and second layers. The production process of laminated glass generally involves initial pressing and high-pressure bonding processes to tightly bond the first, second, and third layers together.
[0003] However, in the high-pressure process, after the laminated glass is placed on the high-pressure frame and enters the autoclave, when the autoclave reaches a high temperature and high pressure state, the middle layer (i.e., the third layer) softens. The second layer of glass will slide down along the first layer of glass under its own weight, resulting in an edge overlap difference of about 0mm between the laminated glass and the bottom of the high-pressure frame, while the other edge overlap difference of the laminated glass is greater than 1mm, or even close to 2mm, and there may be a reverse overlap difference at the corner. Utility Model Content
[0004] Therefore, it is necessary to provide a positioning rack for glass processing to solve the problems mentioned in the background art.
[0005] One aspect of this utility model provides a positioning rack for glass processing. The glass comprises a first layer, a third layer, and a second layer stacked sequentially, wherein the area of the first layer is larger than the area of the second layer, and the second layer corresponds to the middle position of the first layer. The positioning rack comprises: a body; teeth, wherein multiple teeth are distributed on the body along a first direction, the first direction being the length direction of the body, and adjacent teeth form a tooth groove, the bottom of which is used to support the glass; wherein the bottom of the tooth groove is provided with a support portion, which supports the second layer and / or the third layer when the glass is placed in the tooth groove.
[0006] In some embodiments, the support portion is a protrusion provided at the bottom of the tooth groove, and the height of the support portion is in the range of 0.55mm to 0.65mm.
[0007] In some embodiments, the support portion is a sloping structure protruding from the bottom of the tooth groove, and the height of the support portion is in the range of 0.55mm to 0.65mm.
[0008] In some embodiments, the horizontal width of the teeth is 9 mm to 10 mm.
[0009] In some embodiments, the tip of the tooth includes a rounded corner with a radius of 2.9 mm to 3.5 mm. A first chamfer and a second chamfer are respectively provided on the front and rear sides of the tip of the tooth.
[0010] In some embodiments, the tilt angle of the sloped structure is in the range of 10° to 15°. The overlap between the first layer and the second layer is in the range of 0.55 mm to 0.65 mm.
[0011] In some embodiments, the side of the positioning rack includes a groove.
[0012] In some embodiments, at least one end of the positioning rack is provided with a through hole.
[0013] In some embodiments, the surface roughness of the positioning rack is less than Ra 3.2.
[0014] Another aspect of this application provides a glass processing positioning device, comprising: the positioning rack and the rack seat described above, wherein the side of the positioning rack includes a groove, and the base includes a protrusion that engages with the groove to fix the positioning rack.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the scope of protection of this utility model.
[0026] Figure 1 This is a schematic diagram of the structure of laminated glass according to some embodiments of the present invention.
[0027] like Figure 1 As shown, the laminated glass 100 may include a first layer 110, a second layer 120, and a third layer 130. The first layer 110 and the second layer 120 are glass, and the third layer 130 is an adhesive layer (e.g., a polyvinyl butyral (PVB) adhesive layer, an SGP adhesive layer, an ethylene-vinyl acetate copolymer (EVA) adhesive layer, etc.).
[0028] In some embodiments, the size of the first layer 110 may be larger than the size of the second layer 120. For example, the length or width of the first layer 110 may be 1 mm to 2 mm greater than the corresponding length or width of the second layer 120, so that there is an overlap difference between the first layer 110 and the second layer 120 of the laminated glass, that is, at the edge of the laminated glass, the size of the first layer 110 (e.g., length and / or width) is greater than the size of the second layer 120.
[0029] During the production of laminated glass 100, it needs to be placed on a positioning rack and fed into a high-pressure (e.g., above 11 Bar) and high-temperature (e.g., above 140°C) environment. In this high-pressure process, the third layer 130 may soften, which may cause the second layer 120 to slide down along the first layer 110, thereby increasing the overlap at the top of the laminated glass 100 (e.g., greater than 1 mm), or even causing anti-overlap at the corners.
[0030] In existing technologies, to avoid large overlap and anti-overlap differences, the laminated glass 100 needs to be manually clamped before being placed in the autoclave, which consumes manpower and resources. When the glass cannot be repaired, the cost of that laminated glass is lost, and financial resources such as materials and electricity are wasted. In addition, clamping can also lead to quality problems such as assembly thickness, Mohr's optics, and regenerated bubbles.
[0031] Figure 2 This is a structural diagram of a positioning rack according to some embodiments of the present invention. Figure 3a This is a front view of the positioning rack according to some embodiments of the present invention. Figure 5 This is a top view of the positioning rack according to some embodiments of the present invention.
[0032] like Figure 2 As shown, the positioning rack 200 includes teeth 210 and a body 250. Multiple teeth 210 are distributed on the body 250 along a first direction, which is the length direction of the body 250. Adjacent teeth 210 form a tooth groove 220.
[0033] In some embodiments, such as Figure 5As shown, the width of the lower part 114 of the tooth is greater than the width of the upper part 112, which facilitates the placement of the laminated glass 100 in the tooth groove 220 and prevents the laminated glass 100 from colliding with the tooth 210 and scratching it. In some embodiments, to further reduce the friction between the tooth 210 and the laminated glass 100, the upper part 112 of the tooth is provided with a rounded corner 113. The value of the rounded corner 113 can be set according to actual conditions. For example, the angle of the rounded corner 113 can be set to 47°, and the radius can be set to 2.9mm to 3.5mm. As an example, the radius range of the rounded corner 113 can be set to 2.9mm to 3.5mm, such as specific values of 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, and 3.5mm, as well as any two of the above specific values as endpoints. When the radius of the fillet 113 is less than 2.9 mm, the contact area between the tooth 210 and the laminated glass 100 is small, resulting in excessive pressure. This can easily crush the glass and may even cause the fillet to "bite" into the surface of the laminated glass 100, forming obvious indentations. When the radius of the fillet 113 is greater than 3.5 mm, although the stress is lower, it may lead to an excessively large or unstable contact area between the tooth 210 and the laminated glass 100. Slight, uneven settlement may occur in the contact area, causing changes in the flatness of the laminated glass 100 in that area. Setting the radius of the fillet 113 to 2.9 mm to 3.5 mm provides a sufficiently large and uniform contact surface, which can safely support the laminated glass 100 while minimizing visible support point marks (optical distortion) left on the glass, thus ensuring the optical quality of the laminated glass 100.
[0034] Figure 4 This is a schematic diagram of the teeth according to some embodiments of the present invention. For example... Figure 4 As shown, the upper part 112 of the tooth is provided with a first chamfer 115 and a second chamfer 116 on its front and rear sides, respectively. By providing a rounded corner 113, a first chamfer 115, and a second chamfer 116 at the tip of the tooth 210, it is possible to prevent the laminated glass 100 from colliding with the tooth 210, and at the same time, to prevent sharp corners from causing stress or other defects to the glass. In some embodiments, the surface roughness of the positioning rack 200, especially the surface of the part in contact with the laminated glass 100 (e.g., the tooth 210 and the tooth groove 220), is set to be less than Ra 3.2, thereby facilitating the placement of the laminated glass 100 in the tooth groove 220 while preventing the surface of the tooth 210 from scratching the surface of the laminated glass 100.
[0035] In some embodiments, the width of the tooth 210 can be set to 9 mm to 10 mm. The width of the tooth 210 can be the width of the lower part 114 of the tooth. When the width of the tooth 210 is less than 9 mm, the placement distance of the laminated glass 100 is too small, making it difficult to place the laminated glass 100 stably; when the width of the tooth 210 is set to greater than 10 mm, the number of laminated glass 100 placed decreases, thereby reducing the production efficiency of the laminated glass.
[0036] In some embodiments, a support portion is provided at the bottom of the groove 220. When the laminated glass 100 is placed in the groove 220, the support portion is used to support the second layer 120 and the third layer 130 of the laminated glass 100.
[0037] Figure 3a and Figure 3b This is a front view of the positioning rack according to some embodiments of the present invention. For example... Figure 3a As shown, the supporting portion is a protrusion 222 protruding from the bottom of the groove 220. The size of the protrusion 222 can be determined according to the size of the laminated glass 100. The height of the protrusion 222 can be equal to the desired overlap between the bottom of the first layer 110 and the second layer 120 of the laminated glass 100; for example, the height of the protrusion 222 can be in the range of 0.55 mm to 0.65 mm. The width of the protrusion 222 can be greater than or equal to the sum of the thicknesses of the second layer 120 and the third layer 130 of the laminated glass 100.
[0038] In some embodiments, such as Figure 3b As shown, the supporting part is a convex inclined structure 224 at the bottom of the tooth groove 220, which can prevent the increase of the upper stacking difference during the high temperature and high pressure process of the laminated glass 100, and even the occurrence of reverse stacking difference. In some embodiments, the inclination angle of the inclined structure at the bottom of the tooth groove 220 can be determined according to the following formula (1): , (1) in, This indicates the inclination angle at the bottom of tooth groove 220. This indicates the overlap between the first layer 110 and the second layer 120. This indicates the thickness of the first layer is 110. This indicates the thickness of the second layer is 120, and This indicates the thickness of the third layer, which is 130.
[0039] In some embodiments, the thickness of the first layer 110 or the second layer 120 of the laminated glass 100 can be from 1.9 mm to 2.2 mm, for example, 2.0 mm, 2.1 mm, or 2.2 mm. The thickness of the third layer 130 can be from 0.7 mm to 0.9 mm, for example, 0.75 mm, 0.76 mm, 0.80 mm, or 0.81 mm.
[0040] In some embodiments, the desired overlap between the first layer 110 and the second layer 120 can be from 0.55 mm to 0.80 mm, for example, 0.60 mm, 0.65 mm, 0.70 mm, 0.75 mm, 0.80 mm, 0.85 mm, etc. Preferably, the overlap is from 0.55 mm to 0.75 mm. More preferably, the overlap is from 0.55 mm to 0.65 mm.
[0041] According to the above formula (1), the tilt angle can be 10° to 15°, for example, the tilt angle can be 10°, 11°, 12°, 13°, 14°, 15°, etc. Preferably, the tilt angle is 14° to 15°. As an example only, by using multiple pairs (e.g., 15 pairs) of laminated glass 100 with a total thickness of about 6mm placed in a groove horizontal to the bottom, and measuring the stacking difference after entering a high-pressure environment, the stacking difference at the bottom of the laminated glass 100 is 0 or even negative, while the stacking difference at the top is 1.7mm, which is outside the acceptable range. Using multiple pairs (e.g., 30 pairs) of laminated glass 100 with a total thickness of about 6mm placed on a sloped structure with a tilt angle of 14° in the groove, and measuring the stacking difference after entering a high-pressure environment, the stacking difference at the bottom of the laminated glass 100 is 0.60mm to 0.75mm, which meets the requirements, while the stacking difference at the top is also within the acceptable range. Therefore, by using the positioning rack of this utility model, the inclination angle of the inclined surface structure at the bottom of its tooth groove is set to 10° to 15° (especially 14° to 15°), which can effectively prevent stacking defects caused by high pressure and high temperature during the manufacturing process of laminated glass 100.
[0042] In some embodiments, to reduce the cost of machining the positioning rack, the support portion can preferably be configured as a protruding inclined structure at the bottom of the tooth groove 220. In some embodiments, the bottom of the tooth groove may be provided with a support portion of other shapes, as long as it can support the second layer 120 and / or the third layer 130 of the laminated glass 100.
[0043] In some embodiments, the positioning rack 200 can be detachably or fixedly connected to the base 260 via one or more connection methods, thereby fixing the positioning rack 200 to the base 260. Exemplary connection methods may include, but are not limited to, welding connection, key connection, pin connection, interference fit connection, or any combination thereof.
[0044] In some embodiments, the positioning rack 200 may include at least one groove, such as Figure 6 As shown, the side of the positioning rack 200 includes a groove 230.
[0045] Figure 7 This is a schematic diagram of a positioning device according to some embodiments of the present invention.
[0046] like Figure 7 As shown, the positioning device includes a positioning rack 200 and a base 260. The positioning rack 200 includes a groove, for example, the side of the positioning rack 200 includes a groove 230. The base 260 may include a protrusion 252, which can engage with the groove 230 of the positioning rack 200 to prevent the positioning rack 200 from being positioned perpendicular to its axial direction (e.g., ...). Figure 7 Movement occurs in direction A), damaging the laminated glass protected on the positioning rack 200. In some embodiments, the positioning rack 200 and the base 260 can be connected by threaded connection, pin connection, pressure shaft connection, or a combination thereof.
[0047] As an example only, one or more through holes 240 may be provided on the positioning rack 200, such as... Figure 2 and 5 As shown. A hole structure (e.g., through hole, blind hole, etc.) can also be provided at the position of the through hole 240 on the base 260. The through hole 240 on the positioning rack 200 and the hole structure on the base 260 are connected by, for example, pins, screws, bolts, etc., to fix the positioning rack 200 to the base 260.
[0048] In some embodiments, to prevent the positioning rack 200 from being positioned in its axial direction (e.g.) Figure 7 The movement occurs in the direction shown (B). At least one limiting block may be provided on the base 260 near the end of the positioning rack 200 to limit the positioning rack 200.
[0049] Optionally, the positioning rack 200 may include one or more protrusions, and the base 260 may include one or more grooves. The protrusions on the positioning rack 200 can engage with the grooves on the base 260, thereby preventing the positioning rack 200 from being positioned perpendicular to its axial direction (e.g., ...). Figure 7 It moves in direction A).
[0050] In some embodiments, the material of the positioning rack may include materials with high melting point, good toughness, high mechanical strength, and reasonable price. Exemplary positioning rack materials may include polytetrafluoroethylene (PTFE), polyphenylene sulfide (PPS), polyimide, metals (e.g., stainless steel, aluminum alloys, etc.), and ceramics (e.g., alumina ceramics, silicon nitride ceramics, silicon carbide ceramics, etc.). In some embodiments, equal-sized PTFE pieces may be repeatedly pressurized in an autoclave more than five times, and then machined using a machine tool.
[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
